Abstract
A training device includes a pair of limb encircling cuffs with an elastic band therebetween. On each cuff is a buckle for releasably attaching one end of the tension band thereto. Each buckle includes a frame with a slidable latch therein, the latch having a locking post movable between a first seated and a second unseated position. A ring fastener at the end of the band encircles the seat such that movement of the post to its seated position extends the post through the ring. Movement of the post to the seated position is provided by expansion of a spring as previously compressed by the unseated latch.
Claims14
In an exercise device presenting a pair of cuffs adapted for encircling a selected limb of a user's body and a resistance band extending between the cuffs, the improvement comprising a device for releasable attachment of an end of the resistance band to one of the cuffs, said device comprising:
- a frame for attachment to the cuff, said frame including spaced-apart first and second walls;
- at least one track in said frame extending between said first and second walls;
- a spring having first and second ends, said first end attached to said first wall of said frame;
- a seat in said second wall of said frame;
- a latch having first and second walls with at least one wall extending therebetween,
- said at least one wall in said latch adapted for slidable movement along said at least one track in said frame;
- a post extending from said first latch wall, said post adapted for seating within said frame seat;
- said second end of said spring bearing against said latch, an expansion of said spring sliding said latch in a first direction wherein said post is in said frame seat;
- a slidable movement of said latch along said at least one track moving said latch in a second direction displacing said post from said seat and compressing said spring;
- a fastener at an end of the band, said fastener positioned about said seat upon said displacing of said post from said aperture, an expansion of said spring urging said latch into said first direction and said post through said fastener and into said seat, whereby to connect said respective end of said band about said post.
For use with an exercise device presenting a pair of cuffs adapted for encircling selected limbs of a user's body and a resistance band extending between the cuffs, the improvement comprising a buckle on each cuff for releasable attachment of an end of the resistance band thereto, each said buckle comprising:
- a frame for attachment to the cuff;
- a tongue within said frame and movable between a first normal and a second position relative to said frame;
- means in said frame for defining a course of movement for said tongue between said normal first position and said second position;
- means in said frame for urging said tongue into said first normal position;
- a seat in said frame;
- a post on said tongue, said post in said seat at said first normal position and free of said seat at said second position;
- a fastener at an end of the band, each fastener configured for extension of said post therethrough at said tongue first normal position, a movement of said tongue from said normal position to said second position displacing said post from said fastener, whereby to release the end of the band from said buckle.
