Dual Straps Suspension Training System

Abstract

A device for adjustably suspending a pair of gymnastic rings or handles is described. The device has a power spring to automatically retract a pair of straps attached to the rings onto a spool. There is a lock mechanism that holds the pair of straps and rings in place at a desired height. A release cord is attached to the lock mechanism to allow for the release of the lock mechanism from below. A strap retrieval cord may optionally be attached to a strap to allow retrieval of the pair of straps from below.

I claim: 
     
         1 . A system for vertically suspending two hand grasped devices from an elevated structure and allowing for variations in a common height of the two hand grasped devices, the two hand grasped devices including exercise rings, the system comprising:
 a device frame having an upper end defining a point of attachment for fixed suspension from the elevated structure;   a spool having a rotation axle, the spool axially supported on the device frame at a position between the upper end and the lower end of the device frame;   a coil power spring fixed to the device frame, the coil power spring axially coupled to the spool;   a pair of straps wound onto the spool, the pair of straps extending from the spool towards the lower end of the device frame and extending from the frame to points of attachment on the two hand grasped devices; and   a lock mechanism supported by and positioned on a portion of the device frame, the lock mechanism alternately fixing and releasing the pair of straps to be wound on the spool or unwound from the spool;   wherein release of the lock mechanism allows the pair of straps to be drawn out from the spool or alternately retracted back onto the spool, wherein setting the lock mechanism prevents the pair of straps from movement therethrough in at least a downward direction, and wherein the coil power spring serves to preference the retraction of the straps back onto the spool after being drawn out from the spool when the lock mechanism is released.   
     
     
         2 . The system of  claim 1  wherein the lock mechanism comprises a pivoting cam device that contacts the pair of straps. 
     
     
         3 . The system of  claim 1  further comprising a lock mechanism pull cord attached at an upper end to the lock mechanism and lose at a lower end to be grasped and pulled by the user to release the lock mechanism. 
     
     
         4 . The system of  claim 3  wherein the lock mechanism is preferenced to return to a set condition when a downward force on the pull cord is relieved. 
     
     
         5 . The system of  claim 1  wherein the lock mechanism acts by making direct frictional contact with the pair of straps. 
     
     
         6 . The system of  claim 1  wherein the lock mechanism acts by making direct contact with the spool to interrupt free rotation of the spool. 
     
     
         7 . The system of  claim 1  wherein the lock mechanism acts by making direct contact with the rotation axel to interrupt free rotation of the axel. 
     
     
         8 . The system of  claim 1  wherein the coil power spring is coaxial with the spool and is positioned adjacent to the spool on the device frame.
