Abstract

A wrist exerciser has a rigid platform to receive a person'"'"'s wrist, and a fabric support to hold the wrist to the rigid platform. A hinged arm is pivoted to the rigid platform and is fixed to the fabric support at the palm of the hand, so that as the hand is moved in the extension direction, the hinged arm moves. A rod is pivoted to the hinged arm so that, as the hinged arm moves, the rod moves proximally of the person'"'"'s arm. A spring resists the motion of the rod, so the exercise is against spring tension. A heated or cooled pad can be placed in the arm support to provide therapy during exercise.

Claims

1. An exercise device for exercising the extensor muscles of the wrist, said exercising device comprising a rigid member adaptable to be fixed to the palmer side of a user'"'"'s wrist, a hinged arm pivotal with respect to said rigid member and extending adjacent to the palm of said user'"'"'s hand, means for fixing said hinged arm to said user'"'"'s hand, and resistance means for resiliently resisting motion of said hinged arm when said user'"'"'s hand is moved to exercise the extensor muscles, and including a flexible arm support fixed to said rigid member and to said hinged arm, said flexible arm support constituting a means for fixing said rigid member to a user'"'"'s wrist and said means for fixing said hinged arm to said user'"'"'s hand.

2. An exercise device as claimed in claim 1, including a thermal treatment means disposed at said palmar side of the user'"'"'s wrist.

3. An exercise device as claimed in claim 2, wherein said thermal treatment means is cooled to provide cryotherapy.

4. An exercise device as claimed in claim 1, wherein said flexible arm support includes a first strap across the back of the user'"'"'s hand, and a second strap proximally of the user'"'"'s wrist.

5. An exercise device as claimed in claim 1, further including a block received on said hinged arm, said block being movable with respect to said hinged arm, said block constituting said means for fixing said hinged arm to said user'"'"'s hand.

6. An exercise device as claimed in claim 5, wherein said block defines an opening therethrough for slidably receiving said hinged arm.

7. An exercise device as claimed in claim 1, wherein said hinged arm is angularly related to said rigid member, further including a rod pivotally fixed to said hinged arm and extending generally parallel to said rigid member, and a spring means fixed with respect to said rigid member for resiliently resisting motion of said rod towards the proximal end of said rod.

8. An exercise device as claimed in claim 7, further including a spring housing having a proximal end pivoted to said rigid member, said spring housing defining a central opening, and a spring received within said central opening, said rod extending through said central opening and said spring, saidproximal end of said spring housing defining a hole for slidably receiving said rod therethrough, and stop means for limiting motion of said rod in the distal direction.

9. An exercise device as claimed in claim 1, further including a flexible arm support fixed to said rigid member and to said hinged arm, said arm support constituting a means for fixing said rigid member to a user'"'"'s wrist and said means for fixing said hinged arm to said user'"'"'s hand, said arm support including a first strap across the back of the user'"'"'s hand and a second strap proximally of the user'"'"'s wrist, thermal treatment means disposed at said palmar side of the wrist, said thermal treatment means being cooled to provide cryotherapy.

10. An exercise device as claimed in claim 1, further including a block received on said hinged arm, said block being movable with respect to said hinged arm, said block constituting said means for fixing said hinged arm to said user'"'"'s hand, said block defining an opening therethrough for slidably receiving said hinged arm, said hinged arm being angularly related to said rigid member, and a rod pivotally fixed to said hinged arm and extending generally parallel to said rigid member, a spring means fixed with respect to said rigid member for resiliently resisting motion of said rod towards the proximal end of said rod, and further including a spring housing having a proximal end pivoted to said rigid member, said spring housing defining a central opening, a spring constituting said spring means received within said central opening, said rod extending through said central opening and said spring, said proximal end of said spring housing defining a hole for slidably receiving said rod therethrough, and stop means for limiting motion of said rod in the distal direction.
