Exercise device including adjustable, inelastic straps
View Patent ↗An exercise device having many advantageous features is described, including the ability to provide a user selected resistance from nearly zero resistance to the user's full body weight, the ability to easily adjust between exercises and between users, and the ability to balance the device between reconfigurations to provide for ease-of-use. The device includes an inelastic adjustable length member with two arms and a grip at both ends, and a centrally located anchor that provides for a distribution of the length between the arms. In one embodiment, the exercise device is compact and can be removably attached to a door frame. When grabbing each of the grips and uniformly pulling away from the anchor, the arms of the device center on the anchor.

an anchor having a first portion for mounting to a structure and a second portion including a flexible portion to support said elongated member at a position along said length when both of said grips are pulled in a direction away from said anchor, wherein said flexible portion includes a loop, and wherein said elongated member passes through said loop.
2. The exercise device of claim 1 , wherein said first portion is removably attachable to a structure.
3. The exercise device of claim 2 , wherein said structure is a closed door having a door jamb, wherein said anchor includes a strap that is passable between said closed door and said door jamb and where a part of said first portion is not passable between said closed door and said door jamb.
4. The exercise device of claim 3 , wherein the material of said first portion that contacts said structure is softer than said structure, such that said anchor will not scratch said structure.
5. The exercise device of claim 3 , wherein said second portion includes a loop.
6. The exercise device of claim 2 , wherein said structure is a pole, rail, or stanchion, wherein said first portion includes a strap and a tensioning device, wherein said strap has a length sufficiently long to wrap about said structure, and wherein said tensioning device is adapted for tightening said strap about said structure.
7. The exercise device of claim 1 , wherein said first grip and said second grip are hand grips.
8. The exercise device of claim 1 , wherein at least one of said first grip and said second grip is a finger grip.
9. The exercise device of claim 1 , wherein said elongated member includes at least one strap, said mechanism includes at least one cam buckle, such that said length is adjustable according to the length of strap through said cam buckle.
10. The exercise device of claim 9 , said mechanism further including two cam buckles, wherein one of two cam buckles is adjacent to said first grip and wherein the other of said two cam buckles is adjacent to said second grip.
11. The exercise device of claim 1 , wherein said length of said elongated member is adjustable between 6 feet and 12 feet.
12. An adjustable, inelastic exercise device comprising:
an elongated member including at least one inelastic, flat strap, a pair of ends each having a grip and separated by a length, and a mechanism along said length to adjust said length; and
an anchor having a first portion for mounting said device to a structure and a second portion to support said elongated member at a position along said length when both of said pair of ends are pulled in a direction away from said anchor, wherein said second portion includes a flexible loop, and wherein said elongated member passes through said loop.
13. The exercise device of claim 12 , wherein said first portion is removably attachable to a structure.
14. The exercise device of claim 13 , wherein said structure is a closed door having a door jamb, wherein said first portion includes a strap that is passable between said closed door and said door jamb and an enlarged end that is not passable between said closed door and said door jamb.
15. The exercise device of claim 14 , wherein the material of said anchor that contacts said structure is softer than said structure, such that said anchor will not scratch said structure.
16. The exercise device of claim 14 , wherein said second portion includes a loop.
17. The exercise device of claim 13 , wherein said structure is a pole, rail, or stanchion, wherein said first portion includes a tensioning device, wherein said first portion has a length sufficiently long to wrap about said structure, and wherein said tensioning device is adapted for tightening said strap about said structure.
18. The exercise device of claim 12 , wherein said pair of ends is a first end and a second end, wherein said first end includes a first grip and said second end includes a second grip, and wherein said first grip and said second grip are hand grips.
19. The exercise device of claim 12 , wherein said pair of ends is a first end and a second end, wherein said first end includes a first grip and said second end includes a second grip, and wherein at least one of said first grip and said second grip is a finger grip.
20. The exercise device of claim 12 , wherein said length of said elongated member is adjustable between 6 feet and 12 feet.
21. An adjustable, inelastic exercise device comprising:
an elongated member having a pair of ends separated by a length and a mechanism for adjusting said length, said pair of ends including a first end having a first grip and a second end having a second grip, wherein said elongated member includes at least one inelastic, flat strap and said mechanism includes at least one cam buckle, such that said length is adjustable according to the length of strap through said cam buckle; and
an anchor having a first portion including a strap for mounting said device to a structure and a second portion to support said elongated member at a position along said length where, when both of said grips are pulled by a user to support a portion of the user's weight, said second portion exerts a force on said elongated member sufficient to prevent movement of said elongated member, wherein said second portion includes a flexible loop, and wherein said elongated member passes through said flexible loop.
22. The exercise device of claim 21 , wherein said first grip and said second grip are hand grips.
23. The exercise device of claim 21 , wherein at least one of said first grip and said second grip is a finger grip.
24. The exercise device of claim 21 , wherein said mechanism includes at least one cam buckle spaced from one of said grips.
25. The exercise device of claim 21 , wherein said supporting structure is a closed door having a door jamb, wherein said anchor includes a strap that is passable between said closed door and said door jamb and has a first end for slidably supporting said elongated member and a second end that is not passable between said closed door and said door jamb.
26. The exercise device of claim 25 , wherein the material of said anchor second end that contacts said door and said door jamb is softer than either said door or said door jamb, such that said anchor will not scratch said door or said door jamb.
27. The exercise device of claim 25 , wherein said anchor includes a loop for supporting said elongated member.
28. The exercise device of claim 21 , wherein said structure is a pole, rail, or stanchion, wherein said first portion includes a tensioning device, wherein said strap has a length sufficiently long to wrap about said structure, and wherein said tensioning device is adapted for tightening said strap about said structure.
