The present invention generally relates to a modular strap-based exercise apparatus and method, and more particularly to an apparatus and method for modularly connecting components of a strap-based exercise device.
The present disclosure generally relates to exercise devices, and in particular to a modular exercise device having one or more inelastic straps that is easily configurable for use in performing different exercises in a wide variety of environments.
Resistance exercise devices enable a user to exercise by providing resistance to the movement of a user's body. For example, a resistance exercise device may employ an individual's own bodyweight or allow a user to work one muscle against another by providing resistance to the movement of the user's arms, legs, or torso. Resistance exercise devices typically include either elastic bands or inelastic straps.
Often, resistance exercise devices are configured to attach to a support structure, such as a door, an attachment point on a ceiling, or a specially constructed metal truss. However, such resistance exercise devices often are incapable of working with a wide variety of structures, and thus different devices must be used with each type of support structure. Further, due to differences in height, weight, and/or strength between different users, it may not be possible for a single user to use a single device for a variety of exercises or for different users to use a single device for the same exercise. Accordingly, resistance exercise devices are generally usable for only a limited number of exercises or in only a limited number of circumstances. This requires users to purchase, maintain, and utilize a wide range of resistance exercise devices to perform multiple exercises or to use with different types of support structures.
There is a need to provide a resistance exercise device that is capable of being used for a complete workout for any user, including adjustments that allow a wide range of stances and exercises, and that provides resistance to the user's motion in a form that is useful for exercising. Further, there is a need for a modular resistance exercise device that offers the strength and reliability required by users, while simultaneously being economical to manufacture and not adversely affecting the size and weight of the device. As such, there is a particular need for an improved apparatus and method for connecting portions of a resistance exercise device (such as, for example, straps) together into a number of different configurations.
The presently described apparatus and method overcome the disadvantages of the prior art by providing a novel resistance exercise system.
In accordance with one embodiment of the presently claimed invention, a modular strap-based exercise device is provided, along with a method for configuring such a device and attaching components thereof.
In accordance with an embodiment of the presently claimed invention, an inelastic exercise device is provided comprising:
an elongated member having a pair of ends separated by a length;
a first loop formed by folding a first portion of said elongated member against a second portion of said elongated member, wherein said second portion of said elongated member is proximate to said first portion of said elongated member;
a second loop formed by folding a third portion of said elongated member against said second portion of said elongated member, wherein the third portion of said elongated member is proximate to said second portion of said elongated member and said second loop is proximate to said first loop;
wherein said second portion of said elongated member is secured to said first portion of said elongated member and said third portion of said elongated member.
The following disclosure as a whole may be best understood by reference to the provided detailed description when read in conjunction with the accompanying drawings, drawing descriptions, abstract, background, field of the disclosure, and associated headings. Identical reference numerals, when found on different figures, identify the same elements or functionally equivalent elements. The elements listed in the abstract are not referenced but nevertheless refer by association to the elements of the detailed description and associated disclosure.
The present disclosure is not limited to the particular details of the apparatus depicted, and other modifications and applications may be contemplated. Further changes may be made in the apparatus, device, or methods without departing from the true spirit and scope of the disclosure herein involved. It is intended, therefore, that the subject matter in this disclosure should be interpreted as illustrative, not in a limiting sense.
For purposes of contrasting various embodiments with the prior art, certain aspects and advantages of these embodiments are described where appropriate herein. Of course, it is to be understood that not necessarily all such aspects or advantages may be achieved in accordance with any particular embodiment. Modifications and variations can be made by one skilled in the art without departing from the spirit and scope of the invention including, but not limited to: the use of inelastic members, which are described herein as straps, that are round or have some other cross-sectional shape, and/or which are formed from two or more members joined together, as by stitching or with an adhesive; or the use of different mechanisms for adjusting the length of inelastic member that are known in the field including, but not limited to, buckles, hooks, or winding the inelastic member about a rigid element. Moreover, any one or more features of any embodiment may be combined with any one or more other features of any other embodiment, without departing from the scope of the invention.
Disclosed herein is a modular exercise device that is configured to be supported by, or that is configured to be easily attached to, a variety of supporting structures in a variety of configurations. The modular exercise device allows a user to perform a large number of exercises by easily adjusting the configuration of the device and the length of various portions of the device so as to provide resistance to the user's body.
In order to better understand the presently disclosed modular resistance exercise device, two exemplary prior art resistance exercise devices are generally described below and with reference to
Exercise device 100 includes an anchor 110 and a pair of elongated members 122, indicated as a first elongated member 122a and a second elongated member 122b, on either side of the anchor, as shown schematically in
As used herein, the noun “grip” encompasses any device that is interlockable with part of the human body, that is, any device that can be connected in such a way that a person can transfer a force to the grip, preferably a force equal to some or all of the person's body weight. As used, the verb “grip” refers to the action of interlocking such a device and a body part. When used in an exercise device, a grip is attached to other elements that permit the force to be transferred to another object, including but not limited to a stationary support, a device that can store or release energy (such as an elastic cord or a spring), or another body part. Grips include devices that can be surrounded by a body part—for example, a flexible loop or a hook—or that a body part can surround—such as an elongated member that can fit within the grasp of a user's hand. In this context, a member that can be gripped, or is grippable, is one that can either surround a body part or be surrounded by a body part and has a size and configuration that permits the transfer of force from the user to the grip. A “hand grip” is a grip that is sized for grasping by the hand, a “foot grip” is a grip that is sized for grasping a foot, and a “finger grip” is a grip that is sized for grasping by one or more of a user's fingers.
Anchor 110 provides support for elongated member 120 while still permitting some amount of movement. Specifically, the interaction of anchor 110 and elongated member 120 allows the elongated member 120 to be positioned on the anchor 110, and may also provide resistance to the movement of the elongated member 120 along the anchor 110. Preferably, the resistance is sufficient so that, under some circumstances, the support prevents movement of elongated member 120 along anchor 110, even where there is some mismatch of forces on the ends of the elongated member 120. In this way exercise device 100 may be used for a variety of exercises, for example by changing the length of elongated member 120, for example, and also provide an exercise device that can provide support for the user while exercising.
One type of support is referred to herein, without limitation, as a “frictional support.” Anchors that provide frictional support include, but are not limited to, an element or portion of an element that can support elongated member 120 during exercising, and over which the elongated member 120 can slide. Resistance to the movement of elongated member 120 over anchor 110 may be determined, in part, by the frictional resistance of the elongated member 120 sliding over the anchor 110. For example, elongated member 120 may be configured to slide along anchor 110 while a user positions him or herself. During exercising, a slight mismatch in the pulling forces on the grips 123 is matched by static friction of the frictional support, and the grips 123 do not move while exercising. That is, the static friction between elongated member 120 and anchor 110 generated by the frictional support is sufficient to permit exercises in which elongated member 120 does not slide through anchor 110 while exercising. Means that provide frictional support include elements or portions of elements that form part of or which are attached to an anchor and which can support an elongated member (that may, for example, include grips) and which can allow the elongated member to slide along the supporting anchor and provide frictional resistance to the motion of the elongated member during exercising.
Anchor 110 is used to provide a fixed anchor point for exercise device 100 and to support a user's weight as it is applied to elongated members 122 as indicated by an arrow F in
In one embodiment, the length L is adjustable over a length that allows for a wide range of exercises. Thus, for example and without limitation, length L can be varied in length from approximately 3 feet to 6 feet. In another embodiment, elongated member 122 has a width of approximately 1.5 inches.
When supported by a structure, such as door D (as shown, for example, in
In an alternative embodiment (not shown), elongated members 122 do not include lengthening mechanisms 135. In this embodiment, elongated members 122 are thus substantially inelastic and have a fixed length L between the pair of grips 123.
With reference to
Anchor 410 includes a substantially inelastic, flexible elongated member 413 having an enlarged first end 411 that is wider than the strap, and a second end at attachment 415. Throughout this disclosure, the terms “substantially inelastic” or “inelastic” are used to refer to an element that does not stretch more than 10% during use. As is understood by one of skill in the art, a degree of elasticity is inherent to most materials, particularly when they experience significant loading. Anchor 410 supports each of a pair of elongated members 422, indicated as elongated members 422a and 422b at attachment 415. Each elongated member 422 has a respective end 421, shown as end 421a and 421b, each forming a loop 425, shown as loop 425a and 425b, to support one of a pair of grips 423, shown as grip 423a and 423b. Each elongated member 422 also includes a pair of lengthening mechanisms 435, shown without limitation, as buckle 435a and 435b. In addition, each elongated member 422 includes a member 429, shown as members 429a and 429b, that is sewn to strap 414 at attachment 415.
As noted previously, anchor 410 includes an inelastic, flexible elongated member 413. In one embodiment, the majority of lengths of anchor 410 and elongated members 422 are formed of materials that include, but are not limited to, straps of a webbing of a natural or synthetic material having strength sufficient to support the weight of a device user. Webbing materials include, but are not limited to, one or more of a nylon, polypropylene or other polymeric fibers. It is to be understood that a single length of flexible material can alternatively comprise two or more pieces that are stitched, glued, or otherwise attached to one another. In various embodiments, the length of elongated member 413 from first end 411 to attachment 415 may range from 1 inch to greater than 17 inches. In certain other embodiments, the length of elongated member 413 from first end 411 to attachment 415 is from 1 to 18 inches. Elongated member 413 has an enlarged first end 411 that is wider than the elongated member, and a second end 417 that is attached to arms 422a and 422b.

In an embodiment, the handgrip assembly comprises a combination grip 520 comprising a tubular hand grip 523, a foot grip 522, and a supporting member 525. In other embodiment, alternative grips, such as grip 123, grip 423, or other configurations of hand grips, foot grips, or finger grips, may also be used in place of combination handgrip 520.
In an embodiment, the hand grip assembly further comprises a member 514 with a respective one of a pair of loops 516a, 516b at either end. In an embodiment, the first loop 516a is movably connected to a lengthening mechanism 512 and the second loop 516b is connected to a strap attachment mechanism 518. As shown, by way of example and not limitation, the lengthening mechanism 512 may be a buckle and the strap attachment mechanism 518 may be a carabiner. A strap restraint 524 may secure the free end of the strap 514 proximate to the first loop 516a. In alternative embodiments, other combinations of lengthening mechanisms and strap attachment mechanisms are used (e.g., two lengthening mechanisms, two strap attachment mechanisms) or one or more of the loops 516a, 516b are left free.
The combination grip 520 is attached to the member 514 via a first embodiment of an infinity loop 502. As shown, the infinity loop 502 comprises a single member 510 formed into three distinct loops—loop 504, loop 506, and loop 508. Loop 504 is configured to attach to strap attachment mechanism 518, while loop 508 is configured to attach to strap lengthening mechanism 512. Loop 506 is configured to support the configuration grip 520 via supporting member 525. In an embodiment, loop 506 serves as a frictional support for supporting member 525, which is movable through loop 506. In another embodiment, loop 506 is fixedly connected to supporting member 525.
In an embodiment, loop 506 is configured to constrain the supporting member 525 such that the supporting member 525 is angled away from a user's arm while the combination grip 520 is in use. As shown in
The stacked portions of the member 510 may be secured together. In an embodiment, stitching is used to join the layers of the member 510 together along lines 602 and 604. In an embodiment, additional stitching may be used to connect the layers of the member 510 together in the area between lines 602 and 604. In an embodiment, the stitching along lines 602, 604 form parallel lines of stitching.
By providing multiple infinity loops 702a and 702b on a single strap 700, the strap 700 may be used with high anchor points by users of varying heights or by a single user to perform a wide variety of exercises (such as pull ups, dips, and muscle ups) without needing to adjust the strap 700. Instead, different attachment points on the strap 700 provided by the infinity loops 702a, 702b may be used in connection with a grip assembly.
Lines of stitching 710 are used to hold various portions of the elongated member 708 together, such as near the loops 708a, 708b where the elongated member 708 doubles back on itself. Similarly, three lines of stitching are used to form each of the infinity loops 702a, 702b. In an embodiment, one or two lines of stitching are used. In an alternative embodiment, four or more lines of stitching are used. As discussed herein, in other embodiments, other mechanisms are used to hold portions of the elongated member 708 together so as to form the loops 708a, 708b and the infinity loops 702a, 702b.
Each infinity loop 702a, 702b comprises a pair of opposite component loops. As shown, infinity loop 702a is formed from component loops 704a, 706a and infinity loop 702b is formed from component loops 704b, 706b. Each of the component loops 704a, 704b, 706a, 706b may be attached to a strap attachment mechanism so as to attach a grip, another strap, or another component of a modular exercise device. In an embodiment, the elongated member is wrapped around a support structure proximate loop 708a and strap attachment mechanism 712 is secured to component loop 706a. In this manner, the strap 700 is secured to the support structure and may be used to perform various exercises. In various embodiments, grips (such as, for example, combination grip 520) are attached to one or more of the component loops 704a, 704b, 706a, 706b or loops 708a, 708b. In an embodiment, a strap length adjustment mechanism is operatively connected to the strap 700 so as to permit a user to adjust the distance between the infinity loops 704, 706 or between the ends of the strap 700.
In an embodiment, attachments to component loops 704a, 704b, 706a, 706b are secured so as to direct force towards the opposite end. In other words, in an embodiment, if a grip is attached to component loop 704a or 704b, loop 708a is secured to a support. Similarly, if a grip is attached to component loop 706a or 706b, loop 708b is secured to a support. In this way, the strength of the strap 700 is maximized and the force on the stitching 710 is minimized. In an alternative embodiment, grips may be attached to component loops 704a, 704b, 706a, 706b regardless of whether loop 708a or 708b is secured to a support, increasing the versatility of the strap 700 and enabling its use in connection with a wide variety of exercises.
In an embodiment, a kit is provided for modularly assembling an exercise device. The kit may include one or more combination grips 500 and straps 700. A user may perform various exercises by either connecting one or more of the combination grips 500 to a support structure 900 directly or by connecting one or more of straps 700 to the support structure 900, and connecting one or more of the combination grips 500 to the straps 700. By way of example, a single strap 700 may be connected to a first combination grip 500 via loop 706 a and a second combination grip 500 via loop 706b. One or more strap length adjustment mechanisms 135 and/or strap attachment mechanisms 518 may be provided in the kit to facilitate flexibility in assembling various permutations of components in the kit. Other configurations of the kit will be clear to one of skill in the art based on the present disclosure.
One of skill in the art will recognize that all the various components identified in this disclosure may be made from any material or combination of materials suitable for the expected structural load and environment, without limitation—metals, composites, engineered plastics, natural or synthetic materials, etc.
Furthermore, while the particular preferred embodiments have been shown and described, it is obvious to those skilled in the art that changes and modifications may be made without departing from the teaching of the disclosure. The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as limitation. The actual scope of the disclosure is intended to be defined in the following claims when viewed in their proper perspective, based on the related art.
