Description
TECHNICAL FIELD

The presently disclosed subject matter relates generally to a walking stick that can be used in a variety of outdoor environments. Advantageously, the disclosed walking stick includes a plurality of spring-activated feet that allow the user to easily traverse a wide variety of terrains.


BACKGROUND

Walking sticks are widely used to assist hikers, the elderly, people with ambulatory problems, and the disabled to more safely and securely walk or stand. Most conventional walking sticks include an elongated body with a ground-engaging foot at one end, and a handle for grasping at an opposite end. A user grips the handle of the walking stick when standing or walking, so that force applied by the user against the handle is transmitted to the ground. However, conventional walking sticks have numerous drawbacks. For example, the feet of typical walking sticks are small and make poor contact when striking the ground at an angle. In addition, the design of typical walking stick feet does not allow adequate traction, increasing the possibility for slipping and falling. Further, many walking sticks are unable to effectively distribute the dynamic forces created between the stick and the ground surface. Lastly, when walking through mud and similar hazards, conventional walking sticks are ineffective at pulling the user's feet out of the mud. Rather, they require a large pulling force that can be damaging to the user's knees and hips. It would therefore be beneficial to provide a walking stick with improved shock absorbing and stability characteristics that allows a user to traverse a wide variety of terrains (including mud) easily and effectively.


SUMMARY

In some embodiments, the presently disclosed subject matter is directed to a walking stick comprising a body that includes a first end and an opposed second end, with a length therebetween. The walking stick includes a central support positioned at the second end of the body; the central support defined by a plurality of spring-loaded feet. Each foot comprises a first end attached to an outer edge of the central support and an opposed second end distally positioned from the first end. Each foot also includes a top face and an opposed bottom face, wherein the bottom face includes a hinge. The first end of each foot has a width that is less than the width of the second end. Each foot is configured to flex in an upward or downward direction at the hinge, above and below the central support in response to pressure. Each foot is further configured to flex independently of the other feet.


In some embodiments, the first body end comprises a grip.

Upon reading the following description in light of the accompanying drawing figures, those skilled in the art will understand the concepts of the disclosure and will recognize applications of these concepts not particularly addressed herein. It should be understood that these concepts and applications fall within the scope of the disclosure and the accompanying claims.


The presently disclosed subject matter is generally directed to a versatile walking stick that can be used in a wide variety of environments, including (but not limited to) swamps and wetlands. The term “walking stick” generally refers to any device that can be used to aid walking and/or provide postural support and stability. Walking sticks can be useful for a variety of purposes, such as a support when moving uphill and as a brake when moving downhill. Walking sticks can also be useful as a balance point when crossing streams, swamps, or other rough terrain. FIG. 1 illustrates one embodiment of disclosed walking stick 5 comprising first end 10, opposed second end 15, and body 20 that spans the distance between the two ends. The second end 15 of the walking stick includes two or more feet 25 that extend outwards from central support 45. Advantageously, spring actuated feet 25 are configured to fold under tension when pulled in an upward direction (e.g., out of mud or any other tacky material), as described in detail below. Once freed from the mud, the feet spring upwards and provide a wide surface area that allows a user to easily move through the terrain.


As noted above, walking stick 5 includes first end 10 that can be used to grip or maneuver the device. Thus, a user may grasp the walking stick at or near the first end while walking or performing other tasks, as shown in FIG. 2a. In some embodiments, the walking stick can include grip 30 configured at or near first end 10 that provides added comfort to the user, as shown in FIG. 2b. The grip can have any desired configuration and is not limited to the embodiment shown in the Figures. The optional grip can be constructed from any suitable material, such as (but not limited to) rubber, foam, plastic, fabric, or combinations thereof.


Body 20 spans the distance between first and second ends 10, 15 of the disclosed walking stick, as shown in FIG. 3a. Body 20 can have any suitable length 35, such as about 3-6 feet (e.g., at least/no more than about 3, 3.5, 4, 4.5, 5, 5.5, or 6 feet). However, it should be appreciated that the length of the body is not limited and can be greater or less than the disclosed range. The term “length” refers to the longest straight-line distance between first and second ends 10, 15 of the walking stick.


In some embodiments, body 20 can telescope to provide a variable length. The term “telescoping” refers to two or more parts of the walking stick that are coupled together lengthwise, with one part entering, sliding, or passing within the other part. Thus, in some embodiments, body 20 can include first and second telescoping regions 20a and 20b. As shown in FIGS. 3b and 3c, at least a portion of first region 20a is configured to pass within the interior of second region 20b such that the overall length 35 of the body can be adjusted (e.g., to allow users of varying heights to use walking stick 5). Thus, the external diameter of the first region is less than the inner diameter of the second region. The telescoping feature can be accomplished using any mechanism. For example, in some embodiments, one region of body 20 can include one or more spring-loaded pins 21 that are positioned in openings 22 of an adjacent region, as shown in FIGS. 3d and 3e. However, it should be appreciated that any element can be used to optionally adjust the length of body 20, such as removable regions and the like.


Body 20 can have any desired cross-sectional shape, such as (but not limited to) circular, oval, square, rectangular, triangular, pentagonal, hexagonal, octagonal, and the like. In some embodiments, the body can be hollow (e.g., cylindrical), but can also be solid without a central opening in other embodiments.


Body 20 can have any suitable diameter 40 that allows a user to grasp the walking stick easily and comfortably. The term “diameter” refers to the longest straight line distance that passes through the center in a cross-sectional segment, as shown in FIGS. 4a and 4b. In some embodiments, diameter 40 can be about 1-3 inches (e.g., at least/no more than about 1, 1.5, 2, 2.5, or 3 inches). However, it should be appreciated that the diameter of the walking stick is not limited to the range given above. In some embodiments, the diameter of the walking stick is uniform along the length of the body.


In other embodiments, the diameter of the walking stick can vary. For example, the diameter of the walking stick can be greater towards second end 15 to provide additional support and stability to the device, as shown in FIG. 5a. Alternatively or in addition, the first end of the walking stick can have an increased diameter to provide for easier grasping by the user, as shown in FIG. 5b.


The walking stick body can be constructed from any desired material, such as (but not limited to) metal (e.g., stainless steel, aluminum), wood, plastic, carbon fiber composites, laminates, and the like.


Body 20 can vary aesthetically and can be stained, matte, or glossy in some embodiments. A metal body can be anodized, painted, or powder coated in any desired color. Further, the body can include any suitable pattern (e.g., stripes, camouflage, and the like).


The disclosed walking stick 5 also includes a plurality of feet 25 positioned at first end 10. The term “foot” refers to any supportive element that can move in response to pressure. One embodiment of feet 25 is illustrated in FIGS. 6a and 6b. As shown, each foot is attached to central support 45 that cooperates with second end 15 of the walking stick. In some embodiments, the support is permanently or releasably attached to second end 15 using welding, adhesive, magnets, brackets, screws, bolts, fasteners, and the like. Any connective element can be used, such as (but not limited to) central bore 51 configured to receive a bolt or screw and allows the support and feet to attach to the second end of base 20.


Each foot 25 attaches to the central support via hinge 50 that allows each foot to move independently of the other feet, as shown in FIGS. 6d-6d. The term “hinge” refers to any structure that allows rotation about an axis (such as a spring). Feet 25 can rotate above and below the horizontal (H) at an angle 26 of about 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, or 75 degrees, as shown in FIGS. 6e and 6f. Each foot can therefore flex as the user applies force against the ground or as the user pulls the walking stick from the suction of a muddy terrain.


In some embodiments, each foot extends radially outward from the central support in a symmetrical arrangement (e.g., each foot is equally spaced from one another). In other embodiments, the feet can be grouped or non-uniformly positioned about the central support.


Feet 25 can have any suitable shape. As shown in FIG. 7a, each foot includes first end 55 that is attached to the central support and opposed second end 60. The second end can have a width that is greater than the length of the first end, allowing for a larger surface area when moving the walking stick through mud and other rough terrain. To this end, first end 55 includes first width 65 of about 0.5-2 inches (e.g., at least/no more than about 0.5, 1, 1.5, or 2 inches) in some embodiments and second end 60 includes second width 70 of about 1.5-5 inches (e.g., at least/no more than about 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, or 5 inches) in some embodiments. The term “width” refers to the distance between side edges 75. The large width of the second end of each foot can help prevent the walking stick from sinking in the mud by providing a larger surface area.


Each foot also includes top surface 76 and opposed bottom surface 77 (that faces and contacts the ground), as shown in FIG. 7b. In some embodiments, all or a portion of bottom foot surface 77 is textured to reduce mud adhesion to the foot. The term “textured” includes any of a wide variety of non-smooth elements, such as ridges, bumps, indentations, and the like. One example of a textured bottom surface of a foot is illustrated in FIG. 7c (wherein the bottom surface includes a series of raised bumps 78).


Alternatively or in addition, the bottom surface of each foot can include coating 81 that reduces adhesion of mud, water, and the like to the foot, as shown in FIG. 7d. The coating can include any suitable material, such as (but not limited to) rubber, silicone, hydrophobic material, nanocoating, polymeric material, and the like.


Each foot includes length 80 (e.g., the distance between the first and second ends 55, 60). Length 80 can be about 3-10 inches or more (e.g., at least/no more than about 3, 4, 5, 6, 7, 8, 9, or 10 inches). Each foot also includes thickness 79 of about 0.1-1 inch (e.g., at least/no more than about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, or 1 inch), as shown in FIG. 7b. The term “thickness” refers to the distance between top and bottom surfaces 76, 77 of the foot. It should be appreciated that the thickness of each foot is not limited and can be configured greater or less than the range given above.


In some embodiments, each foot can include extending point 80 configured at second end 60 that increases the surface area of the foot, as shown in FIG. 4e. The unique ridged shape further resists suction by the terrain (e.g., mud) and allows a user to maneuver the stick more easily within and from a muddy surface.


Feet 25 can be constructed from any suitable material, such as (but not limited to) metal, wood, plastic, carbon fiber, and the like.


Walking stick 5 can include any number of feet 25, such as about 3-5 or more. The feet can be uniformly positioned about the outer circumference of the central support, as noted above.


In use, walking stick 5 can be used in a variety of environments, such as during hunting, hiking, and the like. The distinctive shape of each foot (e.g., with a widened or ridged second end) increases the surface area of the feet, allowing the user to exert more pressure and thereby maneuver more easily through the terrain. The spring actuated feet 25 of the walking stick fold under tension when pulled in an upward direction (e.g., out of mud or any other tacky material), as illustrated in FIG. 8a. Once freed from the mud, the feet spring upwards and provide a wide surface area that allows a user to easily move through the terrain, as shown in FIG. 8b.


Thus, the spring-actuated feet of walking stick 5 includes first and second configurations. The first, expanded configuration of FIG. 8b provides a maximum foot surface area that allows a user to easily move through rough terrain, such as mud. Thus, when the walking stick feet as pressed into the mud, pressure exerted by the user on the handle presses the feet into the mud in the expanded configuration. The expanded configuration ensures that the surface area of the feet can support a significant amount of user force (weight) and prevents the stick from sinking significantly further into the mud.


The second, folded configuration allows a user to easily remove the walking stick feet from a muddy surface. Specifically, as the mud holds the feet of the walking stick (due to suction), the feet flex downward, allowing the remainder of the walking stick to be removed from the mud. As a result, the user has leverage to more easily remove the remainder of the walking stick from the mud. Once removed, the feet spring back to the first expanded configuration, as shown in FIG. 8c.


In addition to use with muddy areas, the disclosed walking stick allows a user to traverse uneven terrain more easily. As illustrated in FIG. 9, when moving uphill or downhill, one or more of the spring-loaded feet of walking stick 5 can flex and adjust, providing additional shock absorption and flexibility to the user. Thus, each foot can move independently relative to the other feet in response to a rise or dip in the terrain. As a result, the feet can swing to a suitable angle and allow the user to stand on sloped ground to provide greater user support. Once the walking stick is lifted from the ground, each foot returns to the first, expanded configuration until contact is made with the ground again. As a result, the stick can resists slippage even under unfavorable road conditions (rainy and uneven terrain).


Walking stick 5 provides many advantages over conventional walking sticks. For example, the disclosed walking stick can be easily used by a wide variety of consumers, including children and the elderly.


The unique foot configuration prevents the walking stick from sinking into mud or other soft surfaces.


Walking stick 5 resists slippage and exhibits excellent shock absorbing properties when contacted with a variety of terrains, including uneven surfaces and mud.


The disclosed walking stick is durable and can be effectively used long term for many years.


As described above, although preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
