This application is directed toward an exercise device. More specifically, it is directed toward an exercise device that provides resistance based on a user's own body weight.
Numerous different types of exercise equipment are used today for weight training and cardiovascular workouts. Some of these exercise devices include heavy machinery and/or fixed large equipment. Other of these devices use one or more attached weights. Still other exercise devices allow a user to use his/her own body weight to serve as the load for training. These weight-free devices, generally referred to as resistance training equipment, often include elastic type bands or cords that provide resistance. Elastic devices, however, typically fail to provide a consistent amount of resistance when stretched to different lengths. These elastic devices also often cause users to perform unnatural movements in order to work on particular muscle groups.
At least one resistance-based exercise device is described in U.S. Pat. No. 7,044,896. This patent describes an anchor connected to two arms, each arm made of an inelastic, flexible material, and including handles at the end of each arm. The device described in the U.S. Pat. No. 7,044,896 patent has been commercialized and used for the TRX® training system. This type of device allows a user's hands or feet, when attached to the handles, to move freely in relation to each other and to move freely in any direction. As such, location of the individual handles of this type of device tends to be unstable. As a result, the amount of strength needed to use this type of equipment is substantial, and people who are not already physically fit or in top physical shape may struggle to perform the suggested exercises for this equipment and/or sustain injuries in performing exercises incorrectly.
Therefore, a resistance-based exercise device that provides greater stability and ease of use is desirable. A resistance-based exercise device that is easily portable is also desirable.
The disclosed embodiments describe an exercise device that provides resistance based on a user's own body weight. The exercise device may be a portable device. The device provides stability that allows people having different abilities, from the novice to the expert, to benefit from a number of resistance-based exercises.
The present disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which various embodiments are shown. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, the size and relative sizes of different elements may be exaggerated for clarity. Like numbers refer to like elements throughout.
The first portion 110 may include a rigid member, such as a bar, for example. In one embodiment, the first portion 110 may be held or engaged by a user when performing exercises. First portion 110 is also referred to herein as a rigid portion or member, engagement portion member, or holding portion or member. In one embodiment, the first portion 110 includes a bar 112 and includes grips 114.
The bar 112 may be a rigid bar, having a strength to support a person's full body weight. The bar 112 may be formed, for example, of one or more materials, including a lightweight metal, fiberglass, wood, and/or other strong and relatively lightweight material. The bar 112 may have a thickness sufficient to allow people having different sized hands to grip the bar (for example, approximately 1-inch diameter). The bar may have a length L1 sufficient to allow people having different heights and different length arms to grip the bar in a variety of positions from less than to greater than shoulder-width apart. For example, a bar 112 in an exercise device for children may have a length L1 of between about 2 feet and about 3 feet. A bar 112 in an exercise device for adults may have a length L1 of between about 3 feet and about 4 feet. In one embodiment, the bar is about 36 inches long. In another embodiment, a shorter bar is used that is about 24 inches long. A shorter bar may be more easily portable.
The grips 114 may be positioned along the bar to serve, for example, as hand grips. The grips 114 may be formed, for example, of a malleable, compressible material, such as foam, or rubber. The grips 114 may provide additional cushioning and comfort to a user gripping the bar to perform exercises. In one embodiment, the grips 114 are permanently affixed to the bar using an adhesive. Alternatively, the grips 114 can be integrally formed as part of the bar 112. In one embodiment, the grips 114 may be formed by the surface of bar 112 having a rough texture, such as by sandblasting, being painted with a paint/sand mixture, and/or being etched or grooved, to increase friction between a user's hands and the bar 112. A similar process may be performed on the outer surface of grips that are adhered to the surface of the bar 112. The grips 114 may be spaced at different locations along the bar to allow a user to use different holds on the bar for different types of exercise. For example, three grips 114 for each hand are shown in
In one embodiment, each grip 114 may entirely surround a lengthwise portion the bar 112. However, these grips 114 need not entirely surround the bar, but may only cover a part of the bar that a user will hold. The grips 114 can have a length sufficient to accommodate a person's hands. For example, in one embodiment, each grip is between about 4 inches and about 6 inches long.
In one embodiment, the sets of grips 114 are positioned to guide a user where to hold the bar when performing different types of exercises. For example, the inner grips can be used to exercise a particular muscle group, and middle and outer grips each to exercise other respective muscle groups. Although separate grips 114 are shown, in certain embodiments, other types of hand position indicators may be used to instruct a user where to place his/her hands for different exercises (e.g., a single grip having markings to indicate where to hold the bar for different exercises). The plurality of hand position indicators allow users to easily change between different types of exercises during a workout routine, and to perform the correct exercises based on the locations of the indicators. For example, a continuous length or the entire surface of bar 112 may be suitable for gripping. The bar 112 may have indicators to denote different gripping locations (which may correspond in location to grips 114), such as use of a particular color to denote a gripping location, alphanumeric indicia to denote different gripping locations, and/or pictures to denote gripping locations associated with different exercises.
Although the bar 112 is shown as a straight bar, it may be bent or curved in a way that still allows a user to perform various exercises, such as those discussed below. In addition, although the bar 112 is shown in
Referring again to
In one embodiment, adjustable elongated member 120 is formed of an inelastic material. This provides additional stabilization. For example, in one embodiment, adjustable elongated member 120 is formed of an inelastic, flexible strap 122 made of a synthetic or natural fiber (e.g., nylon, polypropylene, or other polymeric fibers). The strap 122 may use a material and webbing or other construction to give it sufficient strength to support the weight of a person. Other materials or constructions may be used, however, such as a rope, chain, wire, etc.
In one embodiment, adjustable elongated member 120 includes a single strap 122. The use of a single strap allows for a simple design and manufacturing process and greater ease of adjustment. However, multiple straps connected to each other can be used. In one embodiment, whether single or plural straps are used, the adjustable elongated member 120 can be adjusted in length to provide different sized configurations of the exercise device 100. In one embodiment, a first end 121a of the adjustable elongated member 120 is attached to a first connector (e.g., 140a, described in greater detail below), and a second end 121b of the adjustable elongated member 120 is attached to a second connector (e.g., 141b, described in greater detail below). The first end 121a may be, for example, stitched to form a loop that connects around part of a connector 140a. Alternatively, the first end 121a may be attached in other ways (e.g., via an adhesive, a snap, clasp, or other connector). In one embodiment, the first end 121a is fixedly attached to the connector 140a.
The second end 121b of the adjustable elongated member 120 may pass through the second connector 140b. In one embodiment, a device (e.g., strap 122) that forms the adjustable elongated member 120 may be slidably engaged with the connector to allow the length of the adjustable elongated member 120 (e.g., L2+L3) to be changed.
For example, in one embodiment, a strap 122 forms an adjustable elongated member 120 extending from a first end 121a connected to a first connector 140a to a second end 121b connected to a second connector 140b. A first end of the strap 122 may substantially coincide with a first end 121a of the adjustable elongated member 120 (e.g., strap 122 may be sewn into a loop at its first end to loop through a slot of first connector 140a). A second end 123 of the strap 122 may be attached to an adjustment mechanism 124. The adjustment mechanism 124 may be, for example, a buckle, such as a cam buckle, that in one position may slide along the length of an intermediate portion of strap 122, and in another position, may be locked to hold the adjustment mechanism 124 to a user selected position along the intermediate portion of strap 122. The strap 122 may form a loop between the second end 123 of the strap and the location of the adjustment mechanism 124 attached to the intermediate portion of strap 122 (e.g., the user selected position along the intermediate portion of strap 122 to which the adjustment mechanism 124 may be locked). This loop of strap 122 may slide through a slot of second connector 140b at a point which corresponds to the second end 121b of the adjustable elongated member 120. Although the adjustment mechanism 124 is shown in
Connectors 140a and 140b may include one or more different mechanisms that connect the first portion 110 (e.g., the rigid member) to the second portion 120 (e.g., the adjustable elongated member). For example, as shown in
The joint that forms the connector 140 may also be arranged to provide for a desired amount of friction. Different known materials and constructions may be used to allow for a particular desired range of motion. For example, the ball and socket joint 142 may be formed of one or more materials including metal, plastic, and/or other natural or synthetic materials. Different mechanisms and materials, such as for example a Delrin® seal, may be used to reduce and/or control the friction in the connector 140.
The use of a ball joint or other joint allowing rotation around a central axis of the bar 122, combined with a friction that permits rotating of the bar freely but with some resistance, allows the bar to be rotated about its axis when performing exercises in a controlled manner. This allows the user to maintain the same wrist position during a particular exercise, even though the angle of the exercise device 100 with respect to the user's body may be changing. As a result, injuries or joint pain due to improper gripping or improper wrist or elbow positioning can be reduced.
The loop 144 may be formed of a single part, for example, an opening in a metal structure, that surrounds the device (e.g., strap 122) that forms the adjustable elongated member 120. However, the loop 144 may also be formed of two or more moveable parts that together surround the adjustable elongated member 120 or otherwise hold it in place.
One or both of the connectors 140a and 140b can have a construction such as depicted in
In one embodiment, as discussed previously, one of the connectors (e.g., 140a) is fixedly attached to an end of the adjustable elongated member 120. The end of the adjustable elongated member 120 may include a terminal end of a strap 122 placed through the loop 144 of the first connector 140a, which may be stitched, adhered, bolted, or otherwise closed on itself to attach to first connector 140a. The second connector 140b may be slidably engaged with the strap 122, to allow the strap 122 to freely adjust to change the length of the adjustable elongated member 120.
However, the exercise device 100 may have other configurations. For example, both connections between the strap 122 and the loop 144 (e.g., on each of connectors 140a and 140b at ends 121a and 121b of the adjustable elongated member 120) can be slidably engaged, so that both ends of the adjustable elongated member 120 may be adjusted. Alternatively, the strap 122 can be fixedly attached to the loops 144 at both connectors 140a and 140b (e.g., by a stitched loop of the strap). In such a case, if an adjustable second portion 120 is to be used, it can include other mechanisms for adjusting its length (for example, other than a slidably engaged strap).
Third portion 130 may be an anchor configured to attach to an immobile object. In one embodiment, the anchor may include, for example, one or more flexible members 132, and one or more connection mechanisms 133. The one or more flexible members 132 may include, for example, a strap, cord, or other strong and flexible material. The one or more connection mechanisms 133 may include one or more snaps, clasps, carabiners, or other connectors that can lock in order to fasten the exercise device 100 to an immobile object. The anchor 130 may, for example, include a strap fixedly attached at one end to connector 150 (described in more detail below), and including at another end a connector that can connect to and lock with connector 150. For example, in one embodiment, connector 150 is a D-ring, and the other end connector includes a snap or carabiner that can hook onto the D-ring to securedly attach the anchor 130 to an immobile object. As such, the anchor 130 can be used to attach the exercise device 100 to any sturdy object capable of holding the weight and stress exerted by a user (e.g., part of heavy exercise equipment, a ceiling hook or beam, a tree branch, etc.). Because the exercise device 100 is lightweight and includes a flexible anchor 130, it can be transported easily to and from the gym, within the house, outside to a park, or to other locations so that it can be attached and used virtually anywhere that there is a sturdy object to which it can be affixed.
Exemplary connectors 150 for connecting the adjustable elongated member 120 to the anchor 130 are depicted in
In another embodiment, as shown in
Additional examples of anchors are depicted in
Connector 133 may be, for example, a carabiner, snap clip, or other device. Connector 133 may attach in a locked manner around connector 150, in order to anchor the exercise device 100 to an immobile object. Although not shown, flexible member 132 may include an additional D-ring or other connector fixedly attached to flexible member 132 between connector 150 and connector 133. As such, to attach around immobile objects having different sizes, flexible member 132 can be wrapped around the immobile object and can attach to one of the additional D-ring or the connector 150 for a closer fit. In another embodiment, flexible member 132 can be adjustable to have different lengths, to allow it to wrap around and attach to different-sized objects. In certain embodiments, anchor 130 may have a length between connector 133 and connector 150 sufficient to permit the anchor 130 to surround an immobile object having a thickness between, for example about 1 inch to about 6 inches. For example, the length between connector 133 and 150 may be between 1 and 2 feet (e.g., so that it can surround, for example, a bar or post having a thickness of about 1 inch, a piece of exercise equipment having a thickness of about 2-4 inches, or a tree branch or post having a thickness up to about 6 inches). Alternatively, to connect the anchor 130 to an immobile object, connector 133 can be directly attached to a hook or other connection mechanism on the immobile object. In one embodiment, though not shown, anchor may consist only of a connector 133, such that the connector 133 connects to connector 150 and to a hook or other connection mechanism on the immobile object, and does not include a flexible member 132.
Anchor 130′ may be removably attachable to an adjustable elongated member, such as discussed above. One end of the anchor 130′ is configured to attach to the adjustable elongated member, and the other end of the anchor 130′ is configured to be placed in a doorway to secure the anchor to the doorway. For example, to anchor the exercise device using anchor 130′, a user places the securing member 134′ on the outside of a doorway near where the door meets the top door frame when closed. Then, the flexible member 132′ is positioned over the door and under the door frame, so that it remains between the door and the door frame. The flexible member 132′ is extended to the inside of the doorway, so that the connector 133′ is on the inside of the doorway. The connection point between the flexible member 132′ and the securing member 134′ may be in the middle of the securing member 134′, so that when anchored to a doorway, part of the securing member 134′ rests against the door, and another pert of the securing member 134′ rests against the door frame.
The anchor 130′ may attach to a doorway in the manner described above, thus functioning as a door hook. The connector 133′ can then be attached to a connector on the adjustable elongated member, and exercises can be performed with the exercise device securely supported in the doorway.
Although the connectors 140a, 140b, and 150 are described separately in relation to first portion 110, second portion 120, and third portion 130, the connectors may be considered to be part of the first, second, or third portions 110, 120, or 130. For example, connector 150 may permanently affixed to second portion 120 to make it part of second portion 120, or may be permanently affixed to third portion 130 to make it part of third portion 130 (e.g., it can be considered to be part of an anchor, or part of a flexible support portion). As another example, connectors 140a and 140b may be permanently affixed to the first portion 110 and the second portion 120, or part of each connector (e.g., part of a joint or connection device) can be permanently affixed to the first portion 110 and another part of each connector (e.g., the other part of the joint or connection device) can be permanently affixed to the second portion 120.
Referring back to
Because a rigid member, such as bar 112, is connected between a user's hands when the user grips the bar, the exercise device 100 has a greater stability than devices that have separate freely moving handles for each hand. As a result, the exercise device 100 allows users to perform a range of exercises from easier to more difficult.
As discussed earlier, the exercise device 100 may include an adjustment mechanism 124, such as a buckle. As a result, the lengths L2 and L3, as well as the angles a1 and a2 can be easily adjusted using a single adjustment mechanism. As will be discussed below, the ease at which the length of the support portion 120 can be adjusted, the stability the handling portion 110 provides, the versatility the anchor 130 provides, and the portability of the exercise device 100, each allow the exercise device 100 to be used in a variety of locations and for a variety of exercises. In addition, because of its construction and lack of the need for weights, the entire exercise device 100 can be easily transported (e.g., an exemplary weight of the device is between about 5 and 10 pounds).
Examples of setups for two types of exercises that can be performed with the exercise device 100 are shown in
As shown in
As shown in
As discussed above, by using, for example, a single cam buckle and a slidable connector between the support portion 120 and the anchor 130, adjusting the exercise device 100 needs only a single adjustment, which allows a user to perform a range of exercises for all different body parts and muscle groups in an exercise session.
As shown in example (a), a user performs a pull-type exercise holding the bar about chest height. An underhand grip is shown. This stance can be used, for example, to focus on exercising muscles of the back and shoulders. For example, row-type exercises can be performed. The bar can be raised or lowered (e.g., by changing the angle between the extended exercise device and the ground) for each exercise set to exercise different muscle groups and to change the amount of resistance. For example, a ground-to-extended device angle may range from about 30° to about 45°. The user's body angle can also be adjusted to change the amount of resistance or the muscle groups exercised. The grips used can additionally affect the muscle groups exercised.
As shown in example (b), a user performs a pull-type exercise holding the bar about chest height. An overhand grip is shown, as opposed to the underhand grip depicted in example (a). This stance can be used, for example, to vary the muscle groups exercised in example (a) while performing similar exercises.
As shown in example (c), a user performs a pull-type exercise holding the bar about head height or slightly higher. An underhand grip is shown, though an overhand grip can also be used to exercise a different muscle group. This stance can be used, for example, to focus on exercising muscles of the arms, such as the biceps. In one embodiment, the length of the elongation member may be increased compared to exercises (a) and (b) to allow for a ground-to-extended device angle to be more appropriate for this exercise. For example, a ground-to-extended device angle may range from about 10° to about 20°. The user's body angle can also be adjusted to change the amount of resistance or the muscle groups exercised. The grips used can additionally affect the muscle groups exercised.
As shown in example (d), a user performs a more difficult pull-type exercise by placing the user's feet on a vertical support (e.g., a wall, tree), and holding the exercise device at an angle that is closer to 90° with respect to the ground. For example, a ground-to-extended device angle for these exercises may range from about 60° to about 80°. The length of the elongation member may be increased compared to exercises (a)-(b) and/or (c) to allow the bar to reach closer to the ground for this exercise. An overhand or underhand grip can be used, and the bar can be held near a chest level. A user in this position can perform exercises that are more like pull-ups than in the embodiments shown in examples (a)-(c).
In the examples (a)-(d) described above, for certain exercises, the user holds the bar of the exercise device to remain in substantially the same location while the user performs an exercise set. This is made more easy through the use of the exercise device 100 described herein. For example, because both hands hold a single rigid member and do not move in relation to each other, the user's hands need not exert transverse force toward or away from each other or up and down in relation to each other in order to maintain balance. The user therefore does not need to independently balance each hand when performing exercises using the exercise device 100 described herein.
As shown in example (e), a user performs a push-type exercise holding the bar about chest height. An overhand grip is shown. This stance can be used, for example, to focus on exercising muscles of the chest, arms, and shoulders. For example, push-type exercises can be performed that exercise pectoral muscles. The bar can be raised or lowered (e.g., by changing the angle between the extended exercise device and the ground) for each exercise set to exercise different muscle groups and to change the amount of resistance. For example, a ground-to-extended device angle may range from about 30° to about 45°. The user's body angle can also be adjusted to change the amount of resistance or the muscle groups exercised. The hand grips used can additionally affect the muscle groups exercised.
As shown in example (f), a user performs a push-type exercise holding the bar about head height, or just above head height. An overhand grip is shown, though an underhand grip can also be used to exercise a different muscle group. This stance can be used, for example, to focus on exercising muscles of the arms, such as triceps muscles. It also may be used to exercise the abdominal muscles. The bar can be raised or lowered (e.g., by changing the angle between the extended exercise device and the ground) for each exercise set to exercise different muscle groups and to change the amount of resistance. In these exercises, for example, a ground-to-extended device angle may range from about 0° to about 20°. The user's body angle can also be adjusted to change the amount of resistance or the muscle groups exercised. The hand grips used can additionally affect the muscle groups exercised.
As can be seen from the discussion above, by simply adjusting the length of an elongation member connected between ends of a bar, and adjusting a user's body position, an entire exercise routine can be performed including a number of different exercises, and using different amounts of resistance. By including a bar or other rigid member that allows a user's hands to remain in the same position in relation to each other, the types of exercises that can be performed are generally easier to perform, while still providing for a large range of resistance values. In addition, because the exercise device is easily portable and attachable to different objects, a user can perform an exercise routine at any convenient location.
Holding member 160 may include one or more holding devices, such as a foot strap 162, and/or a handle 164. In addition, holding member may include a plurality of connectors (e.g., 166a and 166b) that connect the holding device(s) to a rigid member (e.g., a bar) of the exercise device 100′.
In one embodiment, foot strap 162 is formed of a strap and a padding attached to the strap. The foot strap 162 may have a size sufficient to hold two feet of a user, either at the back heel or ankle, or at the front ankle. The foot strap 162 may hang from two connection points on the rigid member, and may form a curved shape when hung. The foot strap 162 may have a rectangular or oval shape. For example, in one embodiment, when flat, foot strap 162 is between 12 and 16 inches long, and between 4-5 inches wide. Foot strap may be formed of materials such as polymers, cotton, or other fabrics, and may include padding to better cushion the heel or ankle when used.
Each connector 166a and 166b may include one or more parts to secure the foot strap 162 to the bar. For example, each connector 166a and 166b may include a screw eye 167 affixed to the bar, and a snap 168 connected to the screw eye and to the foot strap 162 (e.g., the snap can be a swivel snap having a loop on one end that connects to the foot strap 162 and a spring snap on the other end that connects to the screw eye). In one embodiment, connectors 166a and 166b are symmetrical about the center of the bar, to allow for precision balancing when using the foot strap 162 and/or the handle 164.
The handle 164 may be formed of similar material as the foot strap 162, and may also include padding for cushioning. Handle 164 may be in the form of a strap. Handle 164 may have a size sufficient to allow a user to hold the handle 164 with one hand, or to place one foot in the handle. For example, it may have a length of about 5-8 inches. The handle 164 may be connected to the foot strap 162 using, for example, stitching, and may be reinforced with additional straps 169a, 169b, that are attached to the foot strap (e.g., via stitching). The handle 164 may also be symmetrical about the center of the foot strap 164 and the bar to allow for balanced exercises.
As shown in example (a) of
As shown in examples (b) and (d) of
In example (d), a user lies with her front facing the floor, and supports her body with her outstretched hands, or optionally with her forearms. The user then places her feet in the foothold 162 by resting the front of her ankles on the foothold. The user may start in a plank position, and may pull her legs toward her chest. For these exercises, the bar may not remain in about the same place throughout the exercise, but may move with the user's feet. A ground-to-extended device angle used for this exercise may begin at about 90°, and may change to about 60° when the user's legs are maximally bent. Although not shown, handle 164 may be used for additional single-leg exercises by a user placing one foot in the handle and performing exercises in that position.
In example (c), a user performs squats while holding onto a bar of the exercise device 100 (or 100′). By using the exercise device 100 for assistance while performing squats, a user can relieve pressure on the knees, and can also maintain the correct squat position. Therefore, exercise device 100 may be used to assist users in particular exercises that require balancing. The device 100 may both serve as a balance, and also serve to reduce the amount of weight or pressure on a user's joints, such as the knees.

It will be understood in this specification that when an element is referred to as being “connected” or “coupled” to or “on” another element, it can be directly connected or coupled to or on the other element or intervening elements may be present. In contrast, when an element is referred to as being “directly connected” or “directly coupled” to another element, there are no intervening elements present.
As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items and may be abbreviated as “/”.
It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. Unless indicated otherwise, these terms are only used to distinguish one element from another. For example, a first connector could be termed a second connector, and, similarly, a second connector could be termed a first connector without departing from the teachings of the disclosure.
As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” or “includes” and/or “including” when used in this specification, specify the presence of stated features, regions, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components, and/or groups thereof.
Embodiments described herein will be described referring to different views by way of ideal schematic views. Accordingly, the exemplary views may be modified depending on manufacturing technologies and/or tolerances. Therefore, the disclosed embodiments are not limited to those shown in the views, but include modifications in configuration formed on the basis of manufacturing processes.

The term “permanently” as used herein is intended to convey a permanence within the context of the device's typical use. Therefore, an attachment may be described as a permanent attachment, even though it can, technically speaking, be detached by breaking a solid structure or cutting a stitched or webbed fabric.
The term “inelastic” as used herein is intended to convey either no elasticity, or an amount of elasticity that is negligible in the context of the objects, materials, and actions being described. For example, a member, such as a strap, described as inelastic and including a webbing made of a polymer may have some amount of minimal elasticity to prevent the strap from breaking when stress is applied, but does not allow for significant stretching when used that would affect the nature of the exercises performed.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and/or the present application, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
