BACKGROUND OF THE INVENTION
Technical Field of the Invention

This invention relates generally to relieving stress on the knees when squatting or kneeling and to relieve contact pressure on the knees when kneeling and more particularly to a knee protection system and to a leg protection system.

Description of Related Art

Kneepads are widely used to reduce contact pressure on the knees when a person is kneeling for any length of time. A typical kneepad includes a rigid material outer shell, a cushioning section coupled to the outer shell, straps for wrapping around the leg, and a clips-hook connecting mechanism. When worn, the cushioning section is in contact with the knee and the outer shell is in contact with the surface on which the wearer is kneeling.

Knee savers™ are known to be used by catcher's to reduce stress on the knee and to reduce erosion of cartilage in the knee. In general, a knee saver™ is a plastic covered foam wedge that is attached to a catcher's shin guard straps. When the catcher squats, the back of the thigh and the back of the calf contact the knee saver™, thereby taking stress off of the knee.

It is also known that pants have been designed and manufactured to include “built-in” kneepads. The pants may be designed for hunting, football, military, construction, etc. It is further known that the pants may include a double knee section that has an opening for insertion/extraction of removable kneepads.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is a non-flexed leg diagram of an embodiment of a knee protection system 10 that includes a kneepad 12, a knee relief pad 14, and a coupling mechanism 16. The kneepad 12 may be of a variety of constructions. Examples of a kneepad 12 are described with reference to one or more of FIGS. 7-11. The knee relief pad 14 may be of a variety of constructions. Examples of a knee relief pad 14 are described with reference to one or more of FIGS. 3-6 and FIGS. 41-50. The coupling mechanism 16 may be implemented in a variety of ways. Examples of the coupling mechanism 16 are described with reference to one or more of FIGS. 12-50.

In one or more embodiments, the kneepad 12 and the knee relief pad 14 are secured to the coupling mechanism 16 in one of a variety of ways (e.g., stitching, adhesive, riveting, Velcro™ hook and loop fastener, hook and pile fastener, touch fastener, zipper, snap fastener, clip and fastener, push type retainer, etc.) in desired positions. For instance, the kneepad 12 is positioned with respect to the coupling mechanism 16 such that, when a user wears the knee protection system 10, the kneepad 12 at least partially covers the user's knee to reduce direct contact with a kneeling surface when the user is kneeling.

The knee relief pad 14 is positioned with respect to the coupling mechanism 16 such that, when the user wears the knee protection system 10 and the user is kneeling or in a squat position, the knee relief pad 14 is in contact with the user's thigh and calf. With the knee relief pad 14 is in contact with the user's thigh and calf, the user's knee experiences less stress and, as such, helps to protect knee cartilage from stress-related damage.

FIG. 2 is a flexed leg diagram of the knee protection system 10 of FIG. 1. As shown, the user's leg is flexed (bent to a kneeling position), which places the kneepad 12 in contact with a kneeling surface (e.g., the ground, a floor, concrete slab, etc.). Further, the knee relief pad 14 is in contact with the user's thigh and calf, which reduces the stress on the knee and reduces the risk of cartilage damage. The thickness of the knee relief pad 14 may be varied to vary the angle of the leg when in this position. For example, a thicker knee relief pad 14 decreases the angle of the leg, placing more weight on the knee and less on the foot. As another example, a thinner knee relief pad 14 increases the angle of the leg, distributing weight more equally between the knee and the foot.

FIG. 3 is a side view diagram of an embodiment of a knee relief pad 14 that includes a core and a cover. The core includes one or more solid materials, a liquid holding bladder, and/or a gas holding bladder. The cover may be an integral part of the knee relief pad when it includes a liquid holding bladder or a gas holding bladder or it may be a separate component. When the cover is a separate component, it encases the core and may be constructed from leather, plastic, fabric, etc. Note that a solid material may be one of: gel, rubber, silicon, polyurethane foam, high-density foam, high resilient foam, neoprene foam, and other types of foam, cotton, synthetic materials, etc.

The knee relief pad 14 includes a geometric shape that has a first height (h1), a second height (h2), a length (L1), a first angle (φ1), a second angle (φ2), a thigh cup section 15, and a calf cup section 17. The length of the knee relief pad 14 may be in range of a few inches to over a foot; the second height may be a fraction of inch to 6 inches or more, and the first height may be 1.25 times to 5 times, or more, of the second height. The first and second angles are equated based on the length, the first height, and the second height. For instance, tan (φ)=(h1−h2)/L1, where φ=φ1+φ2. Accordingly, φ1=φ−φ2. As an example, if φ1=φ2, then both angles equal ½ φ. As another example, when φ1=0, then φ=φ2. As yet another example, when φ2=0, then φ=φ1.

The thigh cup 15 is a concaved shape (with respect to a portion of the width (w) of the knee relief pad) on the surface of the knee relief pad that comes into contact with the user's thigh. This is illustrated in the cross section view of FIG. 4. The thigh cup 15 may also have a concaved shape with respect to the length (or a portion thereof) of the knee relief pad 14. In general, the thigh cup 15 is intended to better cradle the thigh when it is in contact with the knee relief pad 14, which improves comfort and constituency of fit.

The calf cup 17 is also of a concaved shape (with respect to a portion of the width (w) of the knee relief pad 14) on the surface of the knee relief pad 14 that comes into contact with the user's calf. This is illustrated in the cross section view of FIG. 4. The calf cup 17 may also have a concaved shape with respect to the length (or a portion thereof) of the knee relief pad. The dimensions of the calf cup 17 may be substantially similar to those of the thigh cup, they may be smaller, they may be bigger, or a combination thereof In general, the calf cup 17 is intended to better cradle the calf when it is in contact with the knee relief pad, which improves comfort and constituency of fit.

If the core of the knee relief pad 14 includes a liquid holding bladder, the bladder may be constructed of a non-porous plastic. The liquid may be water, a gel, an oil, etc. The liquid holding bladder may include multiple compartments, each capable of containing the same or different liquid. As such, the geometric shape of the knee relief pad may be adjusted in accordance with the amount of liquid included in the bladder. Further, the softness or hardness may be adjusted by the amount of liquid used and/or the type of liquid used.

If the core of the knee relief pad 14 includes a gas holding bladder, the bladder may be constructed of a non-porous plastic. The gas may be air or other suitable gases. The geometric shape of the knee relief pad may be adjusted in accordance with the amount of gas included in the bladder. Further, the softness or hardness may be adjusted by the amount of gas used.

FIG. 5 is a side view diagram of another embodiment of a knee relief pad 14 that includes a core and a cover. The knee relief pad 14 of FIG. 5 is similar to the knee relief pad of FIG. 3, with the exception that the thigh and/or calf cups 15 and 17 are of different shape. As shown in FIG. 6, both cups span the width of the knee relief pad.

FIGS. 7-11A illustrate inside, outside, and cross-section views of one or more embodiments of a kneepad 12. In general, a kneepad 12 includes a rigid material shell 18 and further includes one or more of an interior foam 20, an interior high friction coefficient material 22, an exterior anti-skid section 24, and an exterior shock absorbing section 26. The rigid material shell 18 may be comprised of one or more of rubber, plastic, metal, carbon fiber, fiberglass, leather, etc.

The kneepad 12 includes a contact surface 30, side encompassing wings 28, and a top encompassing wing 32 to at least partially encompass the knee area of a person wearing the knee protection system 10. The contact surface 30 has a width (w) and length (L) as shown in FIG. 9, has a horizontal concaved shape as shown in FIG. 11, and has a vertical concaved shape as shown in FIG. 11A. Note that the dimensions for the width and length are determined based on the desired area of protection and may range from a few inches to a foot or more. Further note that in various embodiments of the kneepad 12, one or more of the side encompassing wings 28 and/or the top encompassing wing 32 may be omitted.

The dimensions of the horizontal concave shape of FIG. 11 (arc radius, arc angle, arc width, arc height, arc length, and/or arc apothem) vary depending on the desired aspects of the concaved shape. For instance, for a shallow concaved shape, the arch height may be a less than ½ inch and the arch width corresponds to the interior width of the kneepad. For a more pronounced concaved shape, the arch height may be greater than ½ inch and the arch width may be less than the interior width of the kneepad. Further, the exterior arc of the horizontal concaved shape does not have to parallel the interior arc of the horizontal concaved shape. For instance, the exterior arc may be near flat (e.g., arc height of ¼ inch) and the interior arc may be a more pronounced arc shape (e.g., arc height of 1 inch or more). The thickness of the horizontal concaved shape is depending on the material used (e.g., less than a ¼ inch for plastic, metal, fiberglass, carbon fiber and greater than ¼ for leather). Further, the thickness of the horizontal concaved shape may be uniform or may vary depending on the dimensions for the interior arc and the exterior arc of the horizontal concaved shape.

The dimensions of the vertical concave shape of FIG. 11A (arc radius, arc angle, arc width, arc height, arc length, and/or arc apothem) vary depending on the desired aspects of the concaved shape. For instance, for a shallow concaved shape, the arch height may be a less than ½ inch and the arch width corresponds to the interior width of the kneepad. For a more pronounced concaved shape, the arch height may be greater than ½ inch and the arch width may be less than the interior width of the kneepad. Further, the exterior arc of the vertical concaved shape does not have to parallel the interior arc of the vertical concaved shape. For instance, the exterior arc may be near flat (e.g., arc height of ¼ inch) and the interior arc may be a more pronounced arc shape (e.g., arc height of 1 inch or more). The thickness of the vertical concaved shape is depending on the material used (e.g., less than 1/16 inch to ¼ inch for plastic, metal, fiberglass, carbon fiber and about a ¼ inch or more for leather). Further, the thickness of the vertical concaved shape may be uniform or may vary depending on the dimensions for the interior arc and the exterior arc of the horizontal concaved shape.

Each of the side encompassing wings 28 of FIG. 11 has a thickness (t) and a depth (d) and is coupled to the contact surface. Each of the side encompassing wings 28 may have, from a cross-sectional view, a concaved shape, a square shape, a rectangular shape, an elliptical shape, or other shape. The depth of the side encompassing wings 28 may range from ¼ inch to several inches and the thickness depends on the material used and is comparable to the thickness of the contact surface. The side encompassing wings 28 may be of the same material as the contact surface or of a different material. If of the same material, the side encompassing wings 28 may be molded, casted, or otherwise fabricated as part of the kneepad shell.

The top encompassing wing 32 of FIG. 11A has a thickness (t1) and a depth (d1) and is coupled to the contact surface. The top encompassing wing 32 may have, from a cross-sectional view, a concaved shape, a square shape, a rectangular shape, an elliptical shape, or other shape. The depth of the top encompassing wing may range from ¼ inch to several inches and the thickness depends on the material used and is comparable to the thickness of the contact surface. The top encompassing wing may be of the same material as the contact surface or of a different material.

The foam 20, as shown in FIGS. 7, 8, 11, and 11A is coupled (e.g., glued, snapped, or otherwise adhered to) the contact surface 30 to provide contact pressure relief when the user is kneeling. The foam 20 has a geometric shape that corresponds to the interior of the contact surface 30 and is of a thickness to provide a desired level of contact pressure relief, which may vary depending on the type of foam used. For instance, the foam 20 may be polyurethane foam, high-density foam, high resilient foam, neoprene foam, and/or other type of foam.

The high friction coefficient material 22 covers, or at least partially covers, the foam as shown in FIGS. 7, 8, 11, and 11A. The high friction coefficient material 22 minimizes movement of the kneepad, with respect to the user's knee, when the user is moving. For example, the high friction coefficient material 22 may be a soft rubber having a knobby pattern, a line pattern, a cross-hash pattern, or other pattern, to provide a high friction coefficient interior surface of the kneepad 12 while maintaining a level of comfort of the kneepad.

The anti-skid section 24, as shown in FIG. 9, has a geometric shape that corresponds to the exterior of the contact surface. The anti-skid section 24 may be a pattern integrated into the exterior of the contact surface to improve friction between the kneepad 12 and the surface on which the user is kneeling. Alternatively, the anti-skid section 24 may be a separate component that is adhered to the exterior of the contact surface.

The shock absorbing section 26, as shown in FIG. 10, has a geometric shape that corresponds to the exterior of the contact surface. The shock absorbing section 26 may be a pattern (e.g., ripple, corrugated, accordion, or other) integrated into the exterior of the contact surface 30 to reduce the impact of sudden contact between the kneepad and the surface on which the user is kneeling. Alternatively, the shock absorbing section 26 may be a separate component that is adhered to the exterior of the contact surface.

FIG. 12 is a non-flexed leg diagram of an embodiment of a coupling mechanism 16 of a knee protection system 10. The coupling mechanism 16 includes a series of coupling straps 34, a series of connectors, and one or more eyelets 36. Each of the straps 34 may be cloth, plastic, leather, a synthetic cloth, and/or other material. One end of each strap is attached (e.g., glued, riveted, stitched, stapled, etc.) to the kneepad 12 or the knee relief pad 14. The other end of each strap is attached (e.g., glued, riveted, stitched, stapled, etc.) to a male portion of one of the connectors (e.g., Velcro™, buckle, clip, snap, hook and post, etc.). The female portion of the connectors is attached to the kneepad 12 or the knee relief pad 14.

In an example embodiment, a first coupling strap 34 is attached to one edge of the kneepad 12 near the top of the kneepad 12 and the corresponding female portion of the corresponding connector is coupled to the kneepad 12 on the other edge at the top. A second coupling strap 34 is attached to one edge of the kneepad 12 near the bottom of the kneepad and the corresponding female portion of the corresponding connector is coupled to the kneepad 12 on the other edge at the bottom. The one or more eyelets 36 are attached to the second strap 34 and to the top edge of the knee relief pad 14. A third coupling strap 34 is attached to one edge of the knee relief pad 14 and the corresponding female portion of the corresponding connector is coupled to the knee relief pad 14 on the other edge. Note that each of the straps 34 may be adjustable in length.

For this example embodiment, a user puts on the knee relief pad 14 by positioning the kneepad 12 in a desired position and wraps the first and second straps 34 around the back of the leg to secure the straps via the connectors. The user then wraps the third strap 34 around the front of the leg to secure it via the connector. The user may then adjust the length of one or more of the straps 34 to obtain a desired fit.

FIG. 13 is a non-flexed leg diagram of another embodiment of a coupling mechanism 16 of a knee protection system 10. The coupling mechanism 16 includes a series of coupling straps 34 and a series of connectors (not shown). Each of the straps 34 may be cloth, plastic, leather, a synthetic cloth, and/or other material. One end of each strap 34 is attached to the kneepad 12 or the knee relief pad 14. The other end of each strap 34 is attached to a male portion of one of the connectors. The female portion of the connectors is attached to the kneepad or the knee relief pad.

In an example embodiment, a first coupling strap 34 is attached to one edge of the kneepad 12 near the top of the kneepad 12 and the corresponding female portion of the corresponding connector is coupled to the kneepad 12 on the other edge at the top. A second coupling strap 34 is attached to one edge of the kneepad 12 near the bottom of the kneepad 12 and the corresponding female portion of the corresponding connector is coupled to the kneepad on the other edge at the bottom. The second strap 34 is also attached to the top edge of the knee relief pad 14. This may be done directly or through connecting straps that are attached between the second strap and the knee relief pad 14. A third coupling strap 34 is attached to one edge of the knee relief pad 14 and the corresponding female portion of the corresponding connector is coupled to the knee relief pad on the other edge. Note that each of the straps may be adjustable in length.

For this example embodiment, a user puts on the knee relief system by positioning the kneepad 12 in a desired position and the wraps the first and second straps 34 around the back of the leg to secure the straps via the connectors. The user then wraps the third strap around the front of the leg to secure it via the connector. The user may then adjust the length of one or more of the straps to obtain a desired fit.

FIG. 14 is a diagram of another embodiment of a coupling mechanism 16 of a knee protection system 10. The coupling mechanism 16 includes a flexible and expandable material 38, one or more male securing mechanisms 40, and one or more female securing mechanisms 42. The flexible and expandable material 38 may be spandex, neoprene, elastic knit, anti-micro-biotic fabric, a moisture wicking fabric, and/or another type of fabric. The male and female securing mechanisms 40 and 42 are complimentary components of a securing device, which may be one or more of Velcro™, buckles, clips, snaps, hook and post, eyelet and post, button and button hole, tie, etc.

The dimensions of the flexible and expandable material 38 will vary depending on the size of the user. For example, for a large user (e.g., over six feet tall and a thigh circumference of about twenty-five inches) the width would be about 28-33 inches and the length would be about 12-20 inches. For an even larger user, the width and height would be greater and, for a smaller user, the width and height would be less. The flexible and expandable material 38 may be rectangular in shape, may be a quadrilateral where the top edge is of a greater width than the bottom edge to account for the difference in circumference between the thigh and the calf, or other tampered or custom shape. For example, the flexible and expandable material 38 may have a trapezium shape, a trapezoid shape, or an isosceles trapezoid shape.

The kneepad 12 is adhered (e.g., glued, stapled, sewn, stitched, riveted, velcro'ed, clipped, snapped, etc.) to the flexible and expandable material 38 near the top edge and is centered at about one-quarter the width from the right edge. The knee relief pad 14 is adhered to the flexible and expandable material near the bottom edge and is centered about three-quarter the width from the right edge. The male portion of the securing device(s) is attached (e.g., glued, stapled, sewn, stitched, riveted, etc.) along the left edge and the corresponding female portions is attached along the right edge.

FIG. 15 is a non-flexed leg diagram of the coupling mechanism of the knee protection system 10 of FIG. 14 positioned for securing to the leg. As shown, the knee protection system 10 is positioned such that the approximate vertical mid-line of the flexible and expandable material 38 is aligned with approximately the inside mid-line of the leg. The top of the flexible and expandable material 38 is positioned with respect to the thigh such that the vertical center of the kneepad 12 is at a height corresponding to the vertical center of the knee.

FIG. 16 is a non-flexed inside leg diagram of the coupling mechanism 16 of the knee protection system 10 of FIG. 14 secured to the leg. As shown, when the male portion of the securing device(s) is coupled to the female portion of the securing device(s), the knee protection system 10 is secured to the leg. In this position, the kneepad 12 substantially covers the kneecap and the knee relief pad 14 is positioned on the calf such that, when the user squats or kneels, the knee relief pad 14 is located between the thigh and the calf to relieve stress on the knee. From this view, the inside of the knee protection system 10 is free of components that may rub when the user walks.

FIG. 17 is a non-flexed outside leg diagram of the coupling mechanism of the knee protection system 10 of FIG. 14 secured to the leg. From this view, the securing mechanisms 40 and 42 are on the outside of the user's leg such that they do not interfere with the user's movement.

FIG. 18 is a diagram of another embodiment of a coupling mechanism of a knee protection system 10. The coupling mechanism 16 includes a flexible and expandable material 38, one or more male securing mechanisms 40, and one or more female securing mechanisms 42. The flexible and expandable material 38 may be spandex, neoprene, elastic knit, anti-micro-biotic fabric, a moisture wicking fabric, and/or another type of fabric. The male and female securing mechanisms 40 and 42 are complimentary components of a securing device, which may be one or more of Velcro™, buckles, clips, snaps, hook and post, eyelet and post, button and button hole, tie, etc.

In this example embodiment, the flexible and expandable material 38 has a pattern to provide an upper strap 46, a first gap 44, a second gap 45, and a lower strap 48. The overall dimensions of the flexible and expandable material 38 will vary depending on the size of the user as discussed with reference to FIG. 14. The flexible and expandable material may have an overall exterior shape that is rectangular in shape or may be a quadrilateral where the top edge is of a greater width than the bottom edge to account for the difference in circumference between the thigh and the calf. For example, the flexible and expandable material may have a trapezium shape, a trapezoid shape, or an isosceles trapezoid shape. The shape of the gaps 44 and 45 may be rectangular, round rectangular, quadrilateral, elliptical, or other shape, wherein a purpose of including the gap is to substantially eliminate potential for bunching of the flexible and expandable material 38 behind the knee when the leg is bent.

The kneepad 12 is adhered (e.g., glued, stapled, sewn, stitched, riveted, velcro'ed, clipped, snapped, etc.) to the flexible and expandable material near the top edge between the first and second gaps 44, 45, and is centered at about one-quarter the width from the right edge. The knee relief pad 14 is adhered to the flexible and expandable material 38 near the bottom edge within the lower strap 48 and is centered about three-quarter the width from the right edge. The male portion of the securing device(s) is attached (e.g., glued, stapled, sewn, stitched, riveted, etc.) along the left edge and the corresponding female portions is attached along the right edge to corresponding sections of the upper and lower straps.

FIG. 19 is a non-flexed inside leg diagram of the coupling mechanism 16 of the knee protection system of FIG. 18 secured to the leg. As shown, the gap 44 aligns with the back of the knee such that, when the user squats or kneels, the flexible and expandable material 38 does not bunch up behind the knee.

FIG. 20 is a non-flexed outside leg diagram of the coupling mechanism of the knee protection system 10 of FIG. 18 secured to the leg. From this view, the securing mechanisms 40 and 42 are on the outside of the user's leg such that they do not interfere with the user's movement.

FIGS. 21-24 illustrate front, back, inside, and outside views of another embodiment of a coupling mechanism 16 of a knee protection system 10. The coupling mechanism 16 includes a loose fitting flexible and expandable sleeve 50, a kneepad 12, a knee relief pad 14, tightening straps 34, and securing mechanisms 40 and 42. The loose fitting flexible and expandable sleeve 50 may be spandex, neoprene, elastic knit, anti-micro-biotic fabric, a moisture wicking fabric, and/or another type of fabric. Each securing mechanism 40 and 42 includes complimentary components (e.g., male and female) of a securing device, which may be one or more of Velcro™, buckles, clips, snaps, hook and post, eyelet and post, button and button hole, tie, etc.

The dimensions of the loose fitting flexible and expandable sleeve 50 will vary depending on the size of the user. For example, for a large user (e.g., over six feet tall and a thigh circumference of about twenty-five inches) the circumference would be about 28-33 inches and the length would be about 12-20 inches. For an even larger user, the circumference and height would be greater and, for a smaller user, the circumference and height would be less. The loose fitting flexible and expandable sleeve may be cylindrical in shape or may be tapered cylindrical in shape where the top circumference is greater width than the bottom circumference to account for the difference in circumference between the thigh and the calf. Regardless of its particular shape, the circumference of the sleeve is of a sufficiently large size for it to slip over shoes and/or boots worn by the user and positioned about the low thigh, knee, and upper calf area of the leg.

The kneepad 12, as shown in FIG. 21, is adhered (e.g., glued, stapled, sewn, stitched, riveted, velcro'ed, clipped, snapped, etc.) to the front of the sleeve 50 near the top edge. The knee relief pad 14, as shown in FIG. 22, is adhered to the back of the sleeve 50 near the bottom edge.

Each of the tightening straps 34 may adjustable in length and may be comprised of cloth, plastic, leather, a synthetic cloth, and/or other material. One end of each tightening strap 34, as shown in FIG. 23, is attached (e.g., glued, riveted, stitched, stapled, etc.) to the inside of the sleeve 50. On the other end of each strap 34 is attached (e.g., glued, riveted, stitched, stapled, etc.) a male portion of one of the securing device. The female portion of each securing device, as shown in FIG. 24, is attached (e.g., glued, stapled, sewn, stitched, riveted, etc.) to the outside of the sleeve.

FIG. 25 is a non-flexed inside leg diagram of the coupling mechanism 16 of the knee protection system 10 of FIG. 21 positioned for securing to the leg. As shown, the knee protection system 10 is positioned such that the approximate vertical mid-line of the loose fitting flexible and expandable sleeve is aligned with approximately the inside mid-line of the leg. The top of the sleeve 50 is positioned with respect to the thigh such that the vertical center of the kneepad 12 is at a height corresponding to the vertical center of the knee. The tightening straps 34 are secured on the inside of the sleeve. Alternatively, one or more of the tightening straps may be secured on the outside of the sleeve to provide a counter-force when tightening the straps.

FIG. 26 is a non-flexed outside leg diagram of the coupling mechanism of the knee protection system 10 of FIG. 21 positioned for securing to the leg. From this view, the female portions 42 of the securing devices are on the outside of the sleeve 50 and at an approximate vertical mid-line of the outer leg.

FIG. 27 is a non-flexed inside leg diagram of the coupling mechanism of the knee protection system 10 of FIG. 21 secured to the leg. As shown, when the male portion of the securing device(s) is coupled to the female portion of the securing device(s), the knee protection system is secured to the leg. In this position, the kneepad 12 substantially covers the kneecap and the knee relief pad 14 is positioned on the calf such that, when the user squats or kneels, the knee relief pad 14 is located between the thigh and the calf to relieve stress on the knee. From this view, the inside of the knee protection system 10 is free of components that may rub when the user walks. Alternatively, one or more of the female portions of the securing device may be on the inside of the leg.

FIG. 28 is a non-flexed outside leg diagram of the coupling mechanism of the knee protection system 10 of FIG. 21 secured to the leg. From this view, the securing mechanisms 40 and 42 are on the outside of the user's leg such that they do not interfere with the user's movement.

FIG. 29 is a top view diagram of another embodiment of a coupling mechanism 16 of a knee protection system 10. The coupling mechanism 16 includes a kneepad frame 68, a hinge section 66, two size adjusting mechanisms 62, and a knee relief pad frame 60. The coupling mechanism may further include two pivoting mechanisms 64. Each of the components of the coupling mechanism may be comprised of one or more of plastic, metal, fiberglass, carbon fiber, leather, and/or other type material.

From a top perspective (i.e., looking from the hip to the ankle), the kneepad frame 68 has a similar shape to the vertical cross-sectional view of the kneepad 12 of FIG. 11. The kneepad frame 68 further includes a hinge coupling section 66 and a clasping mechanism coupling section 70. For example, one wing and a corresponding set of knuckles of the hinge may be integrated into the kneepad frame 68 and the other wing and other corresponding set of knuckles are integrated into the pivoting mechanism 64 (if included) or into the size adjusting mechanism 62 (if the pivoting mechanism is excluded). As another example, the kneepad frame 68 includes a surface area to which a wing of a hinge is attached (screwed, nut and bolt, riveted, glued, welded, etc.). For this example, the pivoting mechanism 64 or the size adjusting mechanism 62 includes a corresponding surface area to which the other wing of the hinge is attached.

Foam 20 and/or a high friction coefficient material 22 are attached to the inside of the kneepad frame 68. Also, an anti-skid section 24 and/or shock absorbing section 26 may be attached to the outside of the kneepad frame 68. The attaching of these components to the kneepad frame 68 may be done in a similar manner as they are attached to the kneepad 12 in one or more of FIGS. 7-11A.

Also from the top perspective, the knee relief pad frame 60 has a similar shape to the kneepad frame 68. The knee relief pad frame 60 further includes a size adjusting mechanism coupling section 62. For example, the knee relief pad frame 60 includes a surface area to which the size adjusting mechanism is attached (screwed, nut and bolt, riveted, glued, welded, etc.).

Foam 20 and/or a high friction coefficient material 22 are attached to the inside of the knee relief pad frame 60. The attaching of these components to the knee relief pad frame 60 may be done in a similar manner as they are attached to the kneepad 12 in one or more of FIGS. 7-11A. The knee relief pad 14 is attached to the outside of the knee relief pad frame 60.

The size adjusting mechanism 62 allows for the inner circumference of the knee protection system 10 to be increased or decreased depending the circumference of the user's leg. In an example embodiment, the size adjusting mechanism 62 is comprised of the same material as the kneepad frame and includes a first piece and a second piece, each of which includes a slot, which are aligned. Securing hardware is threaded through both slots and the two pieces are adjusted to a desired length. When the two pieces are set at the desired length, the securing hardware is tightened to hold the two pieces in place.

As another example, the size adjusting mechanism 62 includes two pieces of flexible and expandable material (as previously defined), each piece having attached thereto, at one end, a male or female portion of a securing mechanism (e.g., as discussed with reference to FIG. 14). The other end of one of the pieces is attached to the knee relief pad frame 60; the other end of the other piece is attached to the pivoting mechanism 64 (if included) or the hinge 66 (if the pivoting mechanism is not included). As yet another example, the size adjusting mechanism 62 may be incorporated into the clasping mechanism 70 where the clasping mechanism 70 includes ski boot buckles (on both sides or on just one side). Note that the size adjusting mechanism 62 may further adjust for differences in circumferences of a user's leg, which varies from the thigh to the calf.

The pivoting mechanism 64 allows the positioning of the kneepad frame to pivot with respect to the knee relief pad frame 60. In an example, the pivoting mechanism 64 may be a hinge like device that includes two wings, two buckles (one affixed to each of the wings), and a securing pin. The two buckles are side by side from a top perspective.

The clasping mechanism 70 secures the knee protection system about the leg and may be implemented in a variety of ways. For example, the clasping mechanism may be one or more of ski boot buckles, clips, clasps, buckles, Velcro™, buckle-clips (e.g., backpack clips), etc.

FIG. 30 is a top view diagram of the coupling mechanism 16 of the knee protection system 10 of FIG. 29 in an open position. In this position, the knee protection system may be easily positioned about the leg.

FIG. 31 is a front expanded view diagram of the coupling mechanism of the knee protection system 10 of FIG. 29 in an open position. From this perspective, the kneepad frame 68 has an upside down T shape and the knee relief pad frame 60 has a right side up T shape. In this example, the hinge 66 is shown has a convention hinge having two wings, knuckles, and a pin. Alternatively, the hinge 66 could be a piece of flexible material (e.g., cloth, leather) that allows the for the knee protection system to open and close repeatedly.

FIG. 31A is a cross-sectional view diagram of the knee relief pad frame 60 of the knee protection system of FIG. 29. As shown, the knee relief pad frame 60 has a concaved shape behind the knee relief pad to better cradle the calf. The foam and high friction coefficient material have a corresponding concaved shape.

FIG. 31B is a cross-sectional view diagram of the kneepad frame 68 of the knee protection system of FIG. 29. As shown, the kneepad frame 68 has a concaved shape behind the kneepad to better cradle the knee. The foam and high friction coefficient material have a corresponding concaved shape.

FIG. 32 is another front expanded view diagram of the coupling mechanism 16 of the knee protection system 10 of FIG. 29 in an open position. In this embodiment, the coupling mechanism 16 further includes one or more securing strap pairs 76 to facilitated securing the knee protection system 10 to the leg. At the ends of each securing strap pair 76 are male or female securing mechanisms 78 and 80. As shown, one strap pair 76 is attached to the kneepad frame 68 and the other strap pair 76 is attached to the knee relief pad frame 60.

To further facilitate securing the knee protection system to the leg, the coupling mechanism 16 includes a male clasping mechanism 72 and a female clasping mechanism 74. The male clasping mechanism 72 is coupled to the knee relief pad frame 60 and may be implemented similarly to the male coupling mechanism 40. The female clasping mechanism 74 is coupled to the kneepad frame 68 and may be implemented similarly to the female coupling mechanism 42.

FIG. 33 is a non-flexed inside leg diagram of the knee protection system 10 that includes the coupling mechanism of FIG. 31 secured to the leg.

FIG. 34 is a non-flexed outside leg diagram of the knee protection system that includes the coupling mechanism of FIG. 31 secured to the leg.

FIG. 35 is another non-flexed inside leg diagram of the knee protection system that includes the coupling mechanism of FIG. 32 secured to the leg.

FIG. 36 is another non-flexed outside leg diagram of the knee protection system that includes the coupling mechanism of FIG. 32 secured to the leg.

FIG. 37 is a flexed leg diagram of the knee protection system 10 of FIG. 29. As shown, the user's leg is flexed (bent to a kneeling position), which places the kneepad 12 on contact with a kneeling surface (e.g., the ground, a floor, concrete slab, etc.). Further, the knee relief pad 14 is in contact with the user's thigh and calf, which reduces the stress on the knee and reduces the risk of cartilage damage.

FIG. 38 is another front expanded view diagram of the coupling mechanism 16 of the knee protection system 10 of FIG. 29 in an open position. In this embodiment, the knee relief pad frame 60 is rectangular in shape and the kneepad frame 68 is an elongated inverse T shape. The pivoting mechanisms 64 (if included) and the size adjusting mechanisms 62 have the same length as the knee relief pad frame. The components of this embodiment function and may be constructed in a similar manner as the corresponding components of the embodiment of FIG. 29 with different dimensions.

FIG. 39 is another non-flexed inside leg diagram of the coupling mechanism of the knee protection system of FIG. 29 with the coupling mechanism of FIG. 38 secured to the leg.

FIG. 40 is another non-flexed outside leg diagram of the coupling mechanism of the knee protection system of FIG. 29 with the coupling mechanism of FIG. 38 secured to the leg.

FIGS. 41 and 42 are non-flexed inside and outside leg view diagrams of another embodiment of a knee protection system 10. The knee protection system 10 includes a kneepad 12, a plurality of supporting rods 82, 90, a thigh harness 84, a calf harness 88, securing straps 92, and degree locking pivot mechanisms 86. The supporting rods 82, 90 may be comprised of plastic, wood, steel, fiberglass, carbon fiber, nylon resin, and/or other material that provides structural support and can be shaped to a desired shape. The calf and thigh harnesses 84 and 88 may be comprised of a breathable, flexible, and/or expandable material such as cloth, a mesh, leather, etc. The inside of each of the harnesses 84 and 88 may include a padding material such as foam or like material. The securing straps 92 may be implemented as previously discussed with reference to one or more of FIGS. 12, 13, 23, 24, and 32. The kneepad 12 may be implemented as previously discussed with reference to FIGS. 7-11A. The degree locking pivot mechanism 86 may be a quick set hinge, a bilateral hinge, or some other structure similar to the ones used on adjustable range knee braces or the like.

In this example, the supporting rods include two calf support rods 90 (one on the inside and the other on the outside), two thigh supporting rods 82 (one on the inside and the other on the outside), and two kneepad supporting rods 91 (one of the inside and the other on the outside). The cross-sectional shape of the support rods may be circular, elliptical, rectangular with square or rounded corners, or other shape. The length of the supporting rods may be adjustable to customize the fit for a given user.

On the inside of the leg, as shown in FIG. 41, the calf, the thigh, and the kneepad supporting rods are mechanically coupled to a degree locking pivot mechanism 86. The mechanically coupling includes one or more of screws, nuts and bolts, rivets, welding, adhesive, and/or other means. This also occurs on the outside of the leg as shown in FIG. 42.

The degree locking pivot mechanism 86 allows the leg to easily bend up to a particular degree (e.g., five degrees or more). At this particular degree, the degree locking pivot mechanism 86 locks, preventing the leg from bending any further. When this occurs, the thigh presses into the thigh harness and the calf presses into the calf harness, which supports the leg and reduces stress on the knee.

FIG. 43 is a flexed leg diagram of the knee protection system of FIGS. 41 and 42. In this example, the kneepad 12 is contact with the kneeling surface to reduce contact pressure on the knee. As is also shown in this example, the degree locking pivot mechanisms 86 are locked at a particular angle, which prevents the thigh from directly contacting the calf. As shown, the thigh is resting in the thigh harness and the calf harness is pushing down on the calf In this position, the user's knee experiences less stress and, as such, helps to protect knee cartilage from stress-related damage.

FIGS. 44 and 45 are non-flexed inside and outside leg view diagrams of another embodiment of a knee protection system. The knee protection system 10 includes a kneepad 12, a plurality of supporting rods 82, 90, 91, a thigh flexible and expandable material 94, a calf flexible and expandable material 96, and degree locking pivot mechanisms 86. The supporting rods, the degree locking pivoting mechanisms, and the kneepad may be of similar material and construct as previously described with reference to one or more of FIGS. 41-43.

The calf and thigh flexible and expandable material 9496 may be spandex, neoprene, elastic knit, anti-micro-biotic fabric, a moisture wicking fabric, and/or another type of fabric. One end of each of the calf and thigh flexible and expandable material 9496 is secured to an inside leg supporting rod as shown. On the other end of each of the calf and thigh flexible and expandable material 9496 is attached a male securing mechanism 40. The corresponding female securing mechanism 42 is attached to the securing rods on the outside of the leg. Note that the inside of the calf and thigh flexible and expandable material 9496 may include a padding material such as foam or like material.

In this example, to secure the knee protection system 10 to the leg, the calf and thigh flexible and expandable materials 9496 are wrapped around the calf and thigh, respectively, and secured to the female securing mechanisms. When secured to the leg, the degree locking pivot mechanisms allow the leg to easily bend up to a particular degree (e.g., five degrees or more). At this particular degree, the degree locking pivot mechanism locks, preventing the leg from bending any further. When this occurs, the thigh presses into the thigh flexible and expandable material and the calf presses into the calf flexible and expandable material, which supports the leg and reduces stress on the knee.

FIG. 46 is a flexed leg diagram of the knee protection system 10 of FIGS. 44 and 45. In this example, the kneepad 12 is contact with the kneeling surface to reduce contact pressure on the knee. As is also shown in this example, the degree locking pivot mechanisms 86 are locked at a particular angle, which prevents the thigh from directly contacting the calf. As shown, the thigh is resting in the thigh flexible and expandable material 94 and the calf flexible and expandable material 96 is pushing down on the calf. In this position, the user's knee experiences less stress and, as such, helps to protect knee cartilage from stress-related damage.

FIG. 47 is a non-flexed inside leg view diagram of an embodiment of adjustable knee relief pad 14 positioning of a knee protection system 10. The knee protection system 10 includes a kneepad 12, a coupling mechanism 16, a knee relief pad 14 and an adjustable positioning mechanism 98. The kneepad 12 and the coupling mechanism 16 may be implemented as previously discussed with reference to one or more of the preceding figures.

The adjustable positioning mechanism 98 is attached (e.g., glued, stapled, sewn, stitched, riveted, velcro'ed, clipped, snapped, etc.) to the coupling mechanism 16. The knee relief pad 14 is coupled to the adjustable positioning mechanism 98, which allows the knee relief pad 14 to be positioned on the calf in a variety of places (e.g., closer to the back of the knee, closer to the Achilles tendon, etc.). In one embodiment, the adjustable positioning mechanism 98 includes the male or female portion of a Velcro-type fastener and the other portion is attached to the backside of the knee relief pad 14. In other embodiments, the adjustable positioning mechanism 98 may include clips, snaps, and/or other such types of fasteners. Other examples of the adjustable positioning mechanism are shown in FIGS. 48-50.

FIG. 48 is a diagram of an embodiment of an adjustable knee relief pad positioning mechanism 98 of the knee protection system of FIG. 47. In this example embodiment, the adjustable positioning mechanism 98 comprises a sliding dovetail type system. The pin portion of the sliding dovetail system is attached to the coupling mechanism 16 and the tail portion of the sliding dovetail system is implemented on the backside of the knee relief pad 14. The pin may have a rounded top as shown or other shape where the top is wider than the bottom, with respect to the coupling mechanism.

The fit of the tail portion on the pin portion is tight enough to prevent the knee relief pad 14 from easily falling off but not too tight as to prevent it from being repositioned. When the user is kneeling or squatting, the user compresses the knee relief pad, which further secures it into the desired position along the back of the calf.

FIGS. 49 and 50 are back and side view diagrams of another embodiment of an adjustable knee relief pad positioning mechanism of the knee protection system of FIG. 47. In this example embodiment, the adjustable positioning mechanism 98 includes one or more coupling slides 100102 that are attached to the coupling mechanism. Mating coupling slides 100 are attached to the backside of the knee relief pad 14. The mating coupling slides 100 may have a coupling mechanism at one end to allow for the knee relief pad to be detached from the coupling slides.

When a user wears the knee protection system, the user can adjust the positioning of the knee relief pad 14 by sliding it up (towards the knee) or down (towards the Achilles tendon) via the coupling slides 102, which are attached to the coupling mechanism 16, and mating coupling slides 100. The slides 100102 may be comprised of plastic, rubber, leather, simulated leather, cloth, nylon, and/or other type of material.

FIG. 51 is a non-flexed inside leg view diagram of an embodiment of a leg protection system 11 that includes a kneepad 12, a knee relief pad 14, a foot relief pad 104, and a coupling mechanism 16. The kneepad 12 may be implemented as described with reference to one or more of FIGS. 7-11. The knee relief pad 14 may be implemented as described with reference to one or more of FIGS. 3-6 and FIGS. 41-50. The coupling mechanism 16 may be implemented similarly to the coupling mechanism of FIG. 1, with different dimensions to accommodate the foot relief pad. The foot relief pad 104 may be implemented as will be described with reference to FIGS. 51A and 51B.

In one or more embodiments, the kneepad 12, the knee relief pad 14, and the foot relief pad 104 are secured to the coupling mechanism 16 in one of a variety of ways (e.g., stitching, adhesive, riveting, Velcro™, hook and loop fastener, hook and pile fastener, touch fastener, zipper, snap fastener, clip and fastener, push type retainer, etc.) in desired positions. For instance, the kneepad is positioned with respect to the coupling mechanism such that, when a user wears the leg protection system, the kneepad at least partially covers the user's knee to reduce contact pressure with a kneeling surface when the user is kneeling.

The knee relief pad 14 is positioned with respect to the coupling mechanism 16 such that, when the user wears the knee protection system and the user is kneeling or in a squat position, the knee relief pad is in contact with the user's thigh and calf. With the knee relief pad is in contact with the user's thigh and calf, the user's knee experiences less stress and, as such, helps to protect knee cartilage from stress-related damage.

The foot relief pad 104 is positioned with respect to the coupling mechanism 16 such that, when the user wears the leg protection system and the user is kneeling, the foot relief pad is in contact with the user's shin and/or foot and the kneeling surface. With the foot relief pad 104 is in contact with the user's shin and/or foot and the kneeling surface, the user's foot experiences less stress and, as such, helps reduce fatiguing of the foot and ankle area when the user is kneeling for an extended period of time.

FIG. 51-1 is a non-flexed inside leg view diagram of an embodiment of a leg protection system 11 that includes a kneepad 12, a knee relief pad 14, a foot relief pad 104, and a coupling mechanism 16. In this embodiment, the coupling mechanism 16 includes a combination of a sleeve (upper part around the lower thigh and knee) and a flexible and expandable material that wraps around the lower leg. The upper sleeve includes one or more straps for tightening the leg protection system to the leg. The straps may be similar to the straps of one or more of FIGS. 23-28. The lower wrap includes one or more securing mechanism similar to the ones of one or more of FIGS. 14-20.

FIG. 51A is a side view diagram of an embodiment of a foot relief pad 104 that includes a core and a cover. The core includes one or more solid materials, a liquid holding bladder, and/or a gas holding bladder. The cover may be an integral part of the knee relief pad when it includes a liquid holding bladder or a gas holding bladder or it may be a separate component. When the cover is a separate component, it encases the core and may be constructed from leather, plastic, fabric, etc. Note that a solid material may be one of: gel, rubber, silicon, polyurethane foam, high-density foam, high resilient foam, neoprene foam, and other types of foam, cotton, synthetic materials, etc.

The foot relief pad 104 includes a geometric shape that has a first height (h1), a second height (h2), a length (L1), an angle (φ), a flat surface, and a shin cup section 106. The length of the foot relief pad 104 may be in range of a few inches to over a foot; the second height may be a fraction of inch to 6 inches or more, and the first height may be 1.25 times to 5 times, or more, of the second height. The angle is equated based on the length, the first height, and the second height. For instance, tan (φ)=(h1−h2)/L1.

The shin cup 106 is a concaved shape (with respect to a portion of the width (w) of the foot relief pad) on the surface of the foot relief pad 104 that comes into contact with the user's shin. This is illustrated in the cross section view of FIG. 51B. The shin cup 106 may also have a concaved shape with respect to the length (or a portion thereof) of the foot relief pad 104. In general, the shin cup 106 is intended to better cradle the shin when it is in contact with the foot relief pad, which improves comfort and constituency of fit.

If the core of the foot relief pad 104 includes a liquid holding bladder, the bladder may be constructed of a non-porous plastic. The liquid may be water, a gel, an oil, etc. The liquid holding bladder may include multiple compartments, each capable of containing the same or different liquid. As such, the geometric shape of the foot relief pad 104 may be adjusted in accordance with the amount of liquid included in the bladder. Further, the softness or hardness may be adjusted by the amount of liquid used and/or the type of liquid used.

If the core of the foot relief pad 104 includes a gas holding bladder, the bladder may be constructed of a non-porous plastic. The gas may be air or other suitable gases. The geometric shape of the foot relief pad may be adjusted in accordance with the amount of gas included in the bladder. Further, the softness or hardness may be adjusted by the amount of gas used.

FIG. 52 is a flexed leg diagram of the leg protection system 11 of FIG. 51. As shown, the user's leg is flexed (bent to a kneeling position), which places the kneepad 12 on contact with a kneeling surface (e.g., the ground, a floor, concrete slab, etc.). The knee relief pad 14 is in contact with the user's thigh and calf, which reduces the stress on the knee and reduces the risk of cartilage damage. The foot relief pad 104 is in contact with the user's shin and/or foot and the kneeling surface such that the user's toes have minimal contact with the kneeling surface. In this manner, stress and fatigue of the foot are reduced when the user is kneeling for an extended period of time.

FIG. 53 is a non-flexed inside leg view diagram of another embodiment of a leg protection system 110 that includes an integrated kneepad and foot relief pad 114, a knee relief pad 14, and a coupling mechanism 16. The knee relief pad 14 may be implemented as described with reference to one or more of FIGS. 3-6 and FIGS. 41-50. The coupling mechanism 16 may be implemented similarly to the coupling mechanism of one or more of the previous figures, with dimensions altered to accommodate the integrated kneepad and foot relief pad 114. The integrated kneepad and foot relief pad 114, which includes a kneepad area 112, may be implemented as will be described with reference to FIGS. 53A and 53B.

In one or more embodiments, the integrated kneepad and the foot relief pad 104 and the knee relief pad 14 are secured to the coupling mechanism 16 in one of a variety of ways (e.g., stitching, adhesive, riveting, Velcro™, hook and loop fastener, hook and pile fastener, touch fastener, zipper, snap fastener, clip and fastener, push type retainer, etc.) in desired positions. For instance, the kneepad area 112 of the integrated kneepad and foot relief pad 114 is positioned with respect to the coupling mechanism 16 such that, when a user wears the leg protection system 110, the kneepad area 112 at least partially covers the user's knee to reduce contact pressure with a kneeling surface when the user is kneeling.

The foot relief pad portion of the integrated kneepad and foot relief pad 114 is positioned with respect to the coupling mechanism 16 such that, when the user wears the leg protection system 110 and the user is kneeling, the foot relief pad is in contact with the user's shin and the kneeling surface. With the foot relief pad portion is in contact with the user's shin and the kneeling surface, the user's foot experiences less stress and, as such, helps to fatiguing of the foot and ankle area when the user is kneeling for an extended period of time.

The knee relief pad 14 is positioned with respect to the coupling mechanism such that, when the user wears the knee protection system and the user is kneeling or in a squat position, the knee relief pad is in contact with the user's thigh and calf. With the knee relief pad is in contact with the user's thigh and calf, the user's knee experiences less stress and, as such, helps to protect knee cartilage from stress-related damage.

FIG. 53A is a side view diagram of an embodiment of an integrated kneepad and foot relief pad 14 that includes a core and a cover. The core includes one or more solid materials, a liquid holding bladder, and/or a gas holding bladder. The cover may be an integral part of the knee relief pad when it includes a liquid holding bladder or a gas holding bladder or it may be a separate component. When the cover is a separate component, it encases the core and may be constructed from leather, plastic, fabric, etc. Note that a solid material may be one of: gel, rubber, silicon, polyurethane foam, high-density foam, high resilient foam, neoprene foam, and other types of foam, cotton, synthetic materials, etc.

The integrated kneepad and foot relief pad 114 includes a geometric shape that has a first height (h1), a second height (h2), a third height (h3), a first length (L1), a second length (L2), a third length (L3), a variable length (L_vary), an angle (φ), a flat surface, a shin cup section 118, and a knee cup section 116. The second length, which corresponds to the foot relief pad portion, may be in range of a few inches to over a foot. The third length corresponds to the kneepad portion and may be in the range of a few inches to over a foot. The first, or overall, length is the sum of the second, third, and variable lengths. The variable length will vary depending on the desired lengths for each of the second and third lengths and the target height range of users.

Each of the second and third heights may be a fraction of inch to a few inches. The first height may be 1.25 times to 5 times, or more, of the second height. The angle is equated based on the second length, the first height, and the second height. For instance, tan (φ)=(h1−h2)/L2.

The shin cup 118 is a concaved shape (with respect to a portion of the width (w) of the integrated pad) on the surface of the foot relief pad that comes into contact with the user's shin. This is illustrated in the cross section view of FIG. 53B. The shin cup 118 may also have a concaved shape with respect to the length (or a portion thereof) of the foot relief pad. In general, the shin cup 118 is intended to better cradle the shin when it is in contact with the foot relief pad, which improves comfort and constituency of fit.

The knee cup 116 is a concaved shape as shown in FIG. 53C. The knee cup may further include one or more of an interior foam 20, an interior high friction coefficient material 22, an exterior anti-skid section 24, and/or an exterior shock absorbing section 25.

If the core of the integrated pad 114 includes a liquid holding bladder, the bladder may be constructed of a non-porous plastic. The liquid may be water, a gel, an oil, etc. The liquid holding bladder may include multiple compartments, each capable of containing the same or different liquid. As such, the geometric shape of the integrated pad may be adjusted in accordance with the amount of liquid included in the bladder. Further, the softness or hardness may be adjusted by the amount of liquid used and/or the type of liquid used.

If the core of the integrated pad 114 includes a gas holding bladder, the bladder may be constructed of a non-porous plastic. The gas may be air or other suitable gases. The geometric shape of the integrated pad may be adjusted in accordance with the amount of gas included in the bladder. Further, the softness or hardness may be adjusted by the amount of gas used.

FIG. 54 is a flexed leg diagram of the leg protection system of FIG. 53. As shown, the user's leg is flexed, which places the kneepad area 112 in contact with a kneeling surface. The knee relief pad 14 is in contact with the user's thigh and calf, which reduces the stress on the knee and reduces the risk of cartilage damage. The foot relief pad area of the integrated pad 114 is in contact with the user's shin and/or foot and the kneeling surface such that the user's toes have minimal contact with the kneeling surface. In this manner, stress and fatigue of the foot are reduced when the user is kneeling for an extended period of time. In addition, the kneepad area 112 of the integrated pad 114 is in contact with the kneeling surface to reduce contact pressure on the knee.

FIG. 55 is a non-flexed inside leg view diagram of another embodiment of a catcher's leg protection system 111 that includes a coupling mechanism 16, a knee relief pad 14, a kneepad area 112, above the knee guards 120, a foot guard 122, and an integrated kneepad and foot relief pad 114. The coupling mechanism 16 may be implemented using one or more of the coupling mechanisms discussed herein scaled to cover from the lower thigh to around the ankle. As an example, the coupling mechanism may include a sleeve portion for the lower calf area and one or more flexible and expandable material areas around the knee area (e.g., one above the knee and a second one below the knee).

The exterior of each of the above the knee guards 120, the foot guard 122, and the integrated kneepad and foot relief pad 114 include a hard outer shell to withstand the impact of a baseball traveling at 90 mph or more. For example, the outer shell may be comprised of plastic.

Otherwise, the above the knee guards 120 may be implemented in a similar fashion and one or more of the kneepads discussed herein scaled to wrap around and protect the upper knee area and/or above the knee area. Similarly, the integrated kneepad and foot relief pad 114 may be implemented in a similar fashion and one or more the integrated kneepad and foot relief pads discussed.

The knee relief pad 14, the above the knee guards 120, and the integrated kneepad and foot relief pad 114 are attached to the coupling mechanism using one or more attaching methods as discussed herein. The foot guard 122 is attached to the bottom end of the integrated kneepad and foot relief pad such that the foot relief pad flexes as the foot flexes. Note that the integrated kneepad and foot relief pad may omit the foot relief pad section and have a more conventional catcher's shin guard shape. Further note that a catcher would use a leg protection system on each leg.

FIG. 56 is a flexed leg diagram of the catcher's leg protection system 111 of FIG. 55 with the catcher in a squat position. As shown, the foot guard 122 adjusts its position correspondingly to the position of the foot. As is further shown, the knee relief pad 14 is in contact with the thigh and the calf thereby relieving stress on the knee. Note that the knee relief pad 14 may be attached to the coupling mechanism using an adjustable position mechanism as discussed herein. Further note that the different versions (e.g., longer, more slope, less slope, etc.) may be attached to the coupling mechanism to provide a more custom reduction of stress on the knees. Still further note that the above the knee guards move correspondingly to the movement of the leg to protect the upper knee and/or above the knee area.

FIG. 56A is a flexed leg diagram of the catcher's leg protection system 111 of FIG. 55 with the catcher kneeling on the ground. In this position and if the integrated kneepad and foot relief pad includes the foot relief pad, the foot relief pad takes stress off of the foot.

FIG. 57 is a non-flexed inside leg view diagram of another embodiment of a knee protection system 10 that includes a kneepad 12, a coupling mechanism 16, and a knee relief pad 124. In this example embodiment, the coupling mechanism 16 fits over the thigh and the knee relief pad 124 is positioned on the thigh, which may be in a fixed position or an adjustable position. The coupling mechanism 16 may be implemented using one or more of the coupling mechanisms discussed herein scaled to cover from the thigh and knee areas. Each of the knee relief pad 124 and kneepad 12 are attached to the coupling mechanism using one or more attaching mechanisms and discussed herein or other attaching mechanism. Further, each of the knee relief pad and the kneepad may be implemented using one or more of the corresponding implementations discussion herein.

FIG. 58 is a flexed leg diagram of the knee protection system 10 of FIG. 57. As shown, when the user is kneeling, the kneepad 12 is contact with the ground to relieve contact pressure on the knee. As is further shown, the knee relief pad 124 is in contact with the thigh and the calf to reduce stress on the knee.

FIG. 59 is a diagram of an embodiment of a coupling mechanism 16 of a knee protection system 10 of FIG. 57. The coupling mechanism 16 includes a flexible and expandable material 38, one or more male securing mechanisms 40, and one or more female securing mechanisms 42. The flexible and expandable material 38 may be spandex, neoprene, elastic knit, anti-micro-biotic fabric, a moisture wicking fabric, and/or another type of fabric. The male and female securing mechanisms 40 and 42 are complimentary components of a securing device, which may be one or more of Velcro™, buckles, clips, snaps, hook and post, eyelet and post, button and button hole, tie, etc.

The dimensions of the flexible and expandable material 38 will vary depending on the size of the user. For example, for a large user (e.g., over six feet tall and a thigh circumference of about twenty-five inches) the width would be about 28-33 inches and the length would be about 12-20 inches. For an even larger user, the width and height would be greater and, for a smaller user, the width and height would be less. The flexible and expandable material may be rectangular in shape or may be a quadrilateral where the top edge is of a greater width than the bottom edge to account for the difference in circumference between the upper thigh and the knee. For example, the flexible and expandable material may have a trapezium shape, a trapezoid shape, or an isosceles trapezoid shape.

The kneepad 12 is adhered (e.g., glued, stapled, sewn, stitched, riveted, velcro'ed, clipped, snapped, etc.) to the flexible and expandable material near the bottom edge and is centered at about one-quarter the width from the right edge. The knee relief pad 124 is adhered to the flexible and expandable material near the top edge and is centered about three-quarter the width from the right edge. The male portion of the securing device(s) is attached (e.g., glued, stapled, sewn, stitched, riveted, etc.) along the left edge and the corresponding female portions is attached along the right edge.

FIG. 60 is a diagram of another embodiment of a coupling mechanism 16 of a knee protection system 10 of FIG. 57. The coupling mechanism 16 includes a flexible and expandable material 38, one or more male securing mechanisms 40, and one or more female securing mechanisms 42. The flexible and expandable material 38 may be spandex, neoprene, elastic knit, anti-micro-biotic fabric, a moisture wicking fabric, and/or another type of fabric. The male and female securing mechanisms are complimentary components of a securing device, which may be one or more of Velcro™, buckles, clips, snaps, hook and post, eyelet and post, button and button hole, tie, etc.

In this example embodiment, the flexible and expandable material 38 has a pattern to provide an upper strap 128, a gap 44, and a lower strap 126. The overall dimensions of the flexible and expandable material 38 will vary depending on the size of the user as discussed with reference to FIG. 59. The flexible and expandable material 38 may have an overall exterior shape that is rectangular in shape or may be a quadrilateral where the top edge is of a greater width than the bottom edge to account for the difference in circumference between the thigh and the calf. For example, the flexible and expandable material 38 may have a trapezium shape, a trapezoid shape, or an isosceles trapezoid shape. The shape of the gap 44 may be rectangular, round rectangular, quadrilateral, elliptical, or other shape, wherein a purpose of including the gap is to substantially eliminate potential for bunching of the flexible and expandable material behind the knee.

The kneepad 12 is adhered (e.g., glued, stapled, sewn, stitched, riveted, velcro'ed, clipped, snapped, etc.) to the flexible and expandable material 38 near the bottom edge and is centered at about one-quarter the width from the right edge. The knee relief pad 124 is adhered to the flexible and expandable material 38 near the top edge and is centered about three-quarter the width from the right edge. The male portion of the securing device(s) is attached (e.g., glued, stapled, sewn, stitched, riveted, etc.) along the left edge and the corresponding female portions is attached along the right edge.

FIG. 61 is a diagram of another embodiment of a coupling mechanism 16 of a knee protection system 10 of FIG. 57. From this perspective, the kneepad frame 68 has T shape and the knee relief pad frame 60 has an upside down T shape. In this example, the hinge 66 is shown has a convention hinge having two wings, knuckles, and a pin. Alternatively, the hinge 66 could be a piece of flexible material (e.g., cloth, leather) that allows the for the knee protection system to open and close repeatedly.

FIGS. 62 and 63 are inside and outside view diagrams of another embodiment of a coupling mechanism 16 of a knee protection system of FIG. 57. The coupling mechanism 16 includes a loose fitting flexible and expandable sleeve 50, a kneepad 12, a knee relief pad 14, tightening straps 34, and securing mechanisms 78 and 80. The loose fitting flexible and expandable sleeve may be spandex, neoprene, elastic knit, anti-micro-biotic fabric, a moisture wicking fabric, and/or another type of fabric. Each securing mechanism includes complimentary components (e.g., male and female) of a securing device, which may be one or more of Velcro™, buckles, clips, snaps, hook and post, eyelet and post, button and button hole, tie, etc.

The dimensions of the loose fitting flexible and expandable sleeve 50 will vary depending on the size of the user. For example, for a large user (e.g., over six feet tall and a thigh circumference of about twenty-five inches) the circumference would be about 28-33 inches and the length would be about 12-20 inches. For an even larger user, the circumference and height would be greater and, for a smaller user, the circumference and height would be less. The loose fitting flexible and expandable sleeve may be cylindrical in shape or may be tapered cylindrical in shape where the top circumference is greater width than the bottom circumference to account for the difference in circumference between the upper thigh and the knee area. Regardless of its particular shape, the circumference of the sleeve is of a sufficiently large size for it to slip over shoes and/or boots worn by the user and positioned about the thigh and knee area.

The kneepad 12 is adhered (e.g., glued, stapled, sewn, stitched, riveted, velcro'ed, clipped, snapped, etc.) to the front of the sleeve near the top edge. The knee relief pad 124 is adhered to the back of the sleeve 50 near the bottom edge. Each of the tightening straps 34 may adjustable in length and may be comprised of cloth, plastic, leather, a synthetic cloth, and/or other material. One end of each tightening strap is attached (e.g., glued, riveted, stitched, stapled, etc.) to the inside of the sleeve. On the other end of each strap is attached (e.g., glued, riveted, stitched, stapled, etc.) a male portion of one of the securing device. The female portion of each securing device is attached (e.g., glued, stapled, sewn, stitched, riveted, etc.) to the outside of the sleeve.

FIG. 64 is a non-flexed inside leg view diagram of another embodiment of a leg protection system 11 that includes a kneepad 12, a knee relief pad 124, a foot relief pad 104, and a coupling mechanism 16. The kneepad 12 may be implemented as described with reference to one or more of FIGS. 7-11. The knee relief pad 124 may be implemented as described with reference to one or more of FIGS. 3-6 and FIGS. 41-50. The coupling mechanism 16 may be implemented similarly to the coupling mechanism of FIG. 1, with different dimensions to accommodate the foot relief pad and for the knee relief pad being behind the thigh. The foot relief pad 104 may be implemented as described with reference to FIGS. 51A and 51B.

In one or more embodiments, the kneepad 12, the knee relief pad 124, and the foot relief pad 104 are secured to the coupling mechanism 16 in one of a variety of ways (e.g., stitching, adhesive, riveting, Velcro™, hook and loop fastener, hook and pile fastener, touch fastener, zipper, snap fastener, clip and fastener, push type retainer, etc.) in desired positions. For instance, the kneepad 12 is positioned with respect to the coupling mechanism 16 such that, when a user wears the leg protection system, the kneepad at least partially covers the user's knee to reduce contact pressure with a kneeling surface when the user is kneeling.

The knee relief pad 124 is positioned with respect to the coupling mechanism 16 such that, when the user wears the knee protection system and the user is kneeling or in a squat position, the knee relief pad 124 is in contact with the user's thigh and calf. With the knee relief pad 124 is in contact with the user's thigh and calf, the user's knee experiences less stress and, as such, helps to protect knee cartilage from stress-related damage.

The foot relief pad 104 is positioned with respect to the coupling mechanism 16 such that, when the user wears the leg protection system and the user is kneeling, the foot relief pad is in contact with the user's shin and the kneeling surface. With the foot relief pad 104 is in contact with the user's shin and the kneeling surface, the user's foot experiences less stress and, as such, helps to fatiguing of the foot and ankle area when the user is kneeling for an extended period of time.

FIG. 65 is a non-flexed inside leg view diagram of another embodiment of a knee protection system 10 that includes a kneepad 12, a thigh positioned knee relief pad 124, a calf positioned knee relief pad 14, and a coupling mechanism 16. The kneepad and the coupling mechanism may each be implemented using one or more corresponding embodiments described herein or another type of embodiment.

Each of the knee relief pads 14 and 124 may be implemented as described with reference to one or more of FIGS. 3-6 and FIGS. 41-50. Further, each knee relief pad 14 and 124 is positioned with respect to the coupling mechanism such that, when the user wears the knee protection system and the user is kneeling or in a squat position, the knee relief pads are in contact with each and with the user's thigh and calf. With the knee relief pad is in contact with the user's thigh and calf, the user's knee experiences less stress and, as such, helps to protect knee cartilage from stress-related damage. The thickness and/or angle of each knee relief pad may vary depending on the amount of knee stress relief desired. For example, each knee relief pad may have ½ the thickness and ½ the angle of a single knee relief pad but provide the same amount of knee stress relief. As another example, each knee relief pad may be a different thickness and/or angle than the other.

FIG. 66 is a flexed leg diagram of the knee protection system of FIG. 65. As shown, when the user is kneeling, the kneepad 12 is contact with the ground to relieve contact pressure on the knee. As is further shown, the knee relief pads 14 and 124 are in contact with each other and with the thigh and the calf to reduce stress on the knee.

FIGS. 67-69 are a non-flexed front, side, and rear view diagrams of another embodiment of a knee protection system 10 that includes compression pants 130, kneepads 132, and thigh positioned knee relief pads 134 (one on each leg). The compression pants 130 may be comprised of one or more of spandex, neoprene, elastic knit, anti-micro-biotic fabric, a moisture wicking fabric, and/or another type of fabric. Alternatively, the compression pants 130 may be two compression sleeves that fit around each leg from the upper thigh to about the knee area. With this type of knee protection system, a user may it underneath his or her work pants, sports pants, or other type of pants.

The kneepads 132 are attached to the compression pants using one or more of stitching, adhesive, riveting, Velcro™, hook and loop fastener, hook and pile fastener, touch fastener, zipper, snap fastener, clip and fastener, push type retainer, etc. Further, the kneepad 132 may be implemented as discussed with reference to one or more of FIGS. 7-11A. Alternatively, the kneepads 132 may be implement as discussed as discussed with reference to one or more of FIGS. 7-11A but without the rigid material shell or using a more pliable material than a solid plastic (e.g., an encased gel).

The knee relief pads 134 are attached to the compression pants using one or more of stitching, adhesive, riveting, Velcro™, hook and loop fastener, hook and pile fastener, touch fastener, zipper, snap fastener, clip and fastener, push type retainer, etc. Further, the knee relief pads 134 may be implemented as discussed herein with reference to one or more of the figures.

The pants 140 may be work pants, sports pants, weight lifting pants, etc. Note that if the pants 140 are weight lifting pants, they may further include shin pads at the shin level to protection from a weight lifting bar scrapping the shins. Further note that the kneepads 132, the thigh positioned knee relief pads 134, and the calf positioned knee relief pads 138 are attached to the pants using one or more of stitching, adhesive, riveting, Velcro™, hook and loop fastener, hook and pile fastener, touch fastener, zipper, snap fastener, clip and fastener, push type retainer, etc. Still further note that the pants may omit the thigh positioned knee relief pads 134 or the calf positioned knee relief pads 138.

FIGS. 76 and 77 are a non-flexed front and view diagrams of another embodiment of a knee protection system 10 that includes pants 140, pouches 144 for kneepads, pouches 142 for thigh positioned knee relief pads, and pouches 146 for calf positioned knee relief pads. The pouches 142-146, or pockets, are sized to allow for replaceable kneepads, thigh relief pads, and/or calf relief pads to be inserted and removed. Note that the pants 140 may omit the pouches 142 for the thigh positioned knee relief pads or pouches 146 for the calf positioned knee relief pads.

FIG. 78 is a non-flexed front view diagram of another embodiment of a knee protection system 10 similar to the knee protection system of FIG. 57 with the addition of a detachable sitting stand 150. As such, the knee protection system 10 includes a kneepad 12, a coupling mechanism 16, a knee relief pad 124, and the detachable sitting stand 150. In this example embodiment, the coupling mechanism 16 fits over the thigh and the knee relief pad is positioned on the thigh, which may be in a fixed position or an adjustable position. The coupling mechanism may be implemented using one or more of the coupling mechanisms discussed herein scaled to cover from the thigh and knee areas. Each of the knee relief pad 124 and kneepad 12 is attached to the coupling mechanism 16 using one or more attaching mechanisms and discussed herein or other attaching mechanism. Further, each of the knee relief pad and the kneepad may be implemented using one or more of the corresponding implementations discussion herein.

The detachable sitting stand 150 couples to the knee relief pad 124 and/or to the coupling mechanism 16 to provide further relief on the knees. For example and as shown in FIG. 79, when the user is kneeling, the detachable sitting stand 150 is in contact with the ground and with the knee relief pad 124. FIG. 80 shows a rear view of the detachable sitting stand 150 when the user is kneeling. If the detachable sitting stands 150 are removed, the knee relief pads 124 function as described herein.

As may be used herein, the terms “substantially” and “approximately” provides an industry-accepted tolerance for its corresponding term and/or relativity between items. Such an industry-accepted tolerance ranges from less than one percent to fifty percent and corresponds to, but is not limited to, component values, integrated circuit process variations, temperature variations, rise and fall times, and/or thermal noise. Such relativity between items ranges from a difference of a few percent to magnitude differences. As may also be used herein, the term(s) “configured to”, “operably coupled to”, “coupled to”, and/or “coupling” includes direct coupling between items and/or indirect coupling between items via an intervening item (e.g., an item includes, but is not limited to, a component, an element, a circuit, and/or a module) where, for an example of indirect coupling, the intervening item does not modify the information of a signal but may adjust its current level, voltage level, and/or power level. As may further be used herein, inferred coupling (i.e., where one element is coupled to another element by inference) includes direct and indirect coupling between two items in the same manner as “coupled to”. As may even further be used herein, the term “configured to”, “operable to”, “coupled to”, or “operably coupled to” indicates that an item includes one or more of power connections, input(s), output(s), etc., to perform, when activated, one or more its corresponding functions and may further include inferred coupling to one or more other items. As may still further be used herein, the term “associated with”, includes direct and/or indirect coupling of separate items and/or one item being embedded within another item.

As may be used herein, the term “compares favorably”, indicates that a comparison between two or more items, signals, etc., provides a desired relationship. For example, when the desired relationship is that signal 1 has a greater magnitude than signal 2, a favorable comparison may be achieved when the magnitude of signal 1 is greater than that of signal 2 or when the magnitude of signal 2 is less than that of signal 1. As may be used herein, the term “compares unfavorably”, indicates that a comparison between two or more items, signals, etc., fails to provide the desired relationship.

One or more embodiments have been described above with the aid of method steps illustrating the performance of specified functions and relationships thereof. The boundaries and sequence of these functional building blocks and method steps have been arbitrarily defined herein for convenience of description. Alternate boundaries and sequences can be defined so long as the specified functions and relationships are appropriately performed. Any such alternate boundaries or sequences are thus within the scope and spirit of the claims. Further, the boundaries of these functional building blocks have been arbitrarily defined for convenience of description. Alternate boundaries could be defined as long as the certain significant functions are appropriately performed. Similarly, flow diagram blocks may also have been arbitrarily defined herein to illustrate certain significant functionality.

To the extent used, the flow diagram block boundaries and sequence could have been defined otherwise and still perform the certain significant functionality. Such alternate definitions of both functional building blocks and flow diagram blocks and sequences are thus within the scope and spirit of the claims. One of average skill in the art will also recognize that the functional building blocks, and other illustrative blocks, modules and components herein, can be implemented as illustrated or by discrete components, application specific integrated circuits, processors executing appropriate software and the like or any combination thereof.
