Abstract

An apparatus for treating or training individuals while doing exercises permits a large range of motion while at the same time providing resistance. A hollow spherical housing having a spool and a cord inside is mounted within a support frame which permits the housing to rotate 360 degrees about a central z-axis and further about 120 degrees about the x-axis and the y-axis when the cord contacts the frame. A tension dial permits adjusting the tension applied to the spool to provide resistance as a user pulls the cord from the housing. When the user releases the force on the cord the cord is retracted onto the spool. The base of the support frame has opposing locking lugs which engage keyways in a co-operating socket which can be mounted on a variety of surfaces such as walls, doors and straps for attachment to a wrist or ankle or other body part.

Claims

1. An apparatus for performing exercises with resistance comprising:

a tensile member;

a reel assembly for repeatedly deploying and retracting the tensile member thereon;

a substantially spherical housing for rotatably supporting the reel assembly therein; and

a support for rotatably supporting the housing therein, the support having;

a ring encircling the housing between an equator of the housing and the tensile member so as to retain the housing in the support, the ring supporting the housing for rotation therein;

a base spaced from the ring on an opposing side of the equator from the tensile member for rotationally supporting the housing between the ring and the base; and

two or more arcuate span members from connecting between the base and the ring;

wherein the support has a z-axis extending therethrough, the substantially spherical housing being supported therein for rotation substantially 360 degrees about the z-axis, the housing being further rotational about an x-axis and a y-axis, rotation being limited about the x and y-axes by interference contact of at least the tensile member with the ring.

2. The apparatus of claim 1 wherein the base further comprises bearings supported in the base between the housing and the base for rotation of the housing thereon.

3. The apparatus of claim 1 wherein the ring further comprises bearings supported therein between the housing and the ring for rotation of the housing thereon.

4. The apparatus of claim 1 wherein the housing is rotatable about 120 degrees about the y-axis.

5. The apparatus of claim 1 wherein the housing is hollow, the reel assembly further comprising:

a spool for releasably retaining the tensile member thereon;

means for tensioning the spool for adjusting a tension applied thereon, altering resistance to unwinding the tensile member from the spool; and

means for mounting the reel assembly in the housing.

6. The apparatus of claim 5 further comprising:

a tension dial mounted on an exterior of the housing and connected to the means for tensioning in the housing for remotely adjusting the tension applied to the spool.

7. The apparatus of claim 5 wherein the means for mounting the reel assembly in the hollow housing is a bracket.

8. The apparatus of claim 5 wherein the means for tensioning comprises:

a tape adjustably acting on the spool;

means for indexing connected to a band using means for biasing; and

a gear connected between a tension dial and the means for indexing, wherein when the tension dial is rotated the gear engages the means for indexing for adjusting the tension of the band acting on the spool for increasing or decreasing friction between the band and a portion of the spool so as to increase or decrease the tension applied thereto.

9. The apparatus of claim 8 wherein the means for tensioning further comprises:

a tubular flange extending outwardly from the spool;

a tension ring having a toothed inner surface for engaging the tubular flange and a channeled outer surface for engaging the tape; and

a clutch releasably connected between the toothed inner surface of the tension ring and the tubular flange for permitting co-rotation of the spool and the tension ring when the spool is rotated to release the tensile member and to release the spool for independent rotation when the spool is rotated in an opposite direction for retraction of the tensile member thereon.

10. The apparatus of claim 9 wherein the clutch comprises:

two or more stops moveably mounted in the tubular flange, each stop having an angled engagement face for engaging the toothed inner surface when the spool is rotated to release the tensile member and for releasing the spool therefrom when the spool is rotated in the opposite direction; and

two or more springs, each spring mounted beneath a stop for biasing each stop outwardly from the tubular flange for engagement with the toothed inner surface of the tension ring.

11. The apparatus of claim 8 wherein the means for indexing is a toothed slider mounted in a slot on a stationary bracket, the toothed slider being connected to the tape by a spring.

12. The apparatus of claim 8 wherein the gear is mounted on a shaft, the shaft being connected to the tension dial so as to cause the gear to rotate in engagement with the means for indexing when the tension dial is rotated.

13. The apparatus of claim 1 further comprising a retraction assembly, the retraction assembly comprising:

means for biasing connected to a spool; and

means for connecting the means for biasing to the housing;

wherein when force is applied to the tensile member and the spool is rotated to release the tensile member therefrom, the means for biasing is caused to store energy; and

when the force is released from the tensile member, the means for biasing releases the stored energy causing the spool to move in an opposite direction for retracting the tensile member onto the spool.

14. The apparatus of claim 13 wherein the means for biasing is a spring, wherein the means for connecting is a non-rotating support connecting a first end of the spring to a stationary bracket, and wherein a second end of the spring is connected to the spool, the spring storing energy when wound tightly thereon as the spool is rotated to release the tensile member and releasing energy to return to an original shape causing the spool to rotate in the opposite direction for retracting the tensile member.

15. The apparatus of claim 14 wherein the co-operating socket is adapted to be mounted on a door bracket.

16. The apparatus of claim 14 wherein the co-operating socket is adapted to be mounted on a mounting plate.

17. The apparatus of claim 14 wherein the co-operating socket is adapted to be mounted on a strap.

18. The apparatus of claim 1 wherein an end of the tensile member is adapted for connection to a sleeve for engagement with a grip end of a handheld sport apparatus.

19. The apparatus of claim 1 further comprising a mounting apparatus for mounting the apparatus to a plurality of surfaces.

20. The apparatus of claim 19 wherein in the mounting apparatus further comprises two or more opposing locking lugs extending radially outward from the base and adapted for engaging opposing keyways in a co-operating socket, the co-operating socket being mountable to a plurality of surfaces for engagement of the apparatus therewith.
