Abstract

An exercise apparatus includes a compact resistance unit that houses a pneumatic cylinder. The cylinder is connected to a pulley wheel that moves at least toward the cylinder. A main cable extends about a portion of the pulley wheel. One end of the main cable is fixed to the unit housing and the other end is attached to a pulley block of a block-and-tackle mechanism. A user cable extends through the block-and-tackle mechanism and is connected to a handle. The pneumatic cylinder resists movement of the handle away from the unit.

Claims

1. An exercise station comprising:

a housing including a pneumatic resistance assembly;

a pair of adjustable arms supported by the housing, the arms being disposed on opposite sides of the housing and extending outward from the housing;

a pair of user interfaces, each user interface being movable between a retracted position and an extended position;

a hinge assembly between each arm and the housing so as to allow at least vertical movement of the arm relative to the housing;

a locking mechanism, the locking mechanism allowing a user to releasably select a vertical position of the arm relative to the housing; and

a cable.

2. The exercise station of claim 1, wherein the cable includes a first cable end and a second cable end, the second cable end being connect to one of the pair of user interfaces and the first cable end being connected to the other one of the pair of user interfaces.

3. The exercise station of claim 1 additionally comprising a block-and-tackle mechanism, the cable being attached to the block-and-tackle mechanism.

4. The exercise station of claim 1, wherein each arm has a tubular structure through which the cable passes.

5. The exercise station of claim 1, wherein the hinge assembly includes an inner pulley over which the cable runs.

6. The exercise station of claim 1, wherein each hinge assembly includes a bracket and a lug, the lug being selectively secured relative to the bracket.

7. The exercise station of claim 6, wherein the bracket is disposed on the housing and the lug is disposed on the arm.

8. The exercise station of claim 7, wherein the bracket includes at least two bracket plates, at least a portion of the lug being disposed between the at least two bracket plates.

9. The exercise station of claim 8, wherein the locking mechanism includes a plurality of holes and a dowel, at least a portion of the dowel engaging with one of the plurality of holes when the arm is in the selected vertical position with respect to the housing.

10. The exercise station of claim 9, wherein the plurality of holes are disposed in one of the at least two brackets.

11. The exercise station of claim 10 further comprising a knob, the knob controlling movement of the dowel.

12. The exercise station of claim 11 further comprising a support bracket, the support bracket being fixed to the lug and contacting the knob when the dowel is engaged with the selected one of the plurality of holes.

13. The exercise station of claim 11 further comprising a spring, the spring being disposed so as to bias the dowel to move into the selected one of the plurality of holes.

14. The exercise station of claim 11, wherein one of the plurality of holes is disposed in the bracket so as to allow the arm to be positioned to extend straight down when the dowel is engaged with the hole.

15. The exercise station of claim 11, wherein one of the plurality of holes is disposed in the bracket so as to allow the arm to be positioned to extend straight up when the dowel is engaged with the hole.

16. The exercise station of claim 11, wherein the plurality of holes are spaced in an arcuate pattern along an outer edge of the one of the at least two brackets.

17. The exercising station of claim 11, wherein the pneumatic resistance assembly includes a pneumatic actuator pivotally connected to the housing.

18. The exercise station of claim 17, wherein the pneumatic actuator is arranged to resist movement of the user interfaces toward the extended position.

19. An exercise station comprising:

a frame;

a pneumatic resistance secured to the frame;

a pulley system;

an adjustable arm extending outward from the frame;

a user interface being movable between a retracted position and an extended position;

a hinge between the arm and the frame; and

a locking mechanism for releasably selecting a position of the arm relative to the frame.

20. An exercise apparatus comprising:

a frame;

a pneumatic actuator having a cylinder and a piston rod that extends from the cylinder along a stroke axis, the pneumatic actuator being disposed on the frame;

a pulley wheel rotatably connected to the piston rod;

an adjustable arm extending outward from the frame;

a movable user interface;

a hinge between the arm and the frame;

a locking mechanism for releasably selecting a position of the arm relative to the frame; and

a cable.

21. The exercise apparatus of claim 20, wherein the piston rod is connected to the pulley wheel at a location offset from a center of the pulley wheel.
