WEIGHT-CONTROLLED BAG STRAP AND AUTOMATIC SHOULDER STRAP RETRACTION UNIT

Abstract

The invention relates to a weight-controlled bag strap and an automatic shoulder strap retraction unit designed to reduce the sagging of shoulder straps when bags are hung. The unit comprises the main body (10), the connecting piece (20), the movable main bag strap (30) which moves along a vertical movement guide (40) under the weight of the bag (110), the mechanical transmission element (50), the first and second strap retraction arms (60, 70), the strap retaining slots (80), the return spring (90), and the lower movement limiter (100). When the top carrying handle (130) of the bag is placed on the movable main bag strap (30), the weight of the bag moves the main strap downwards. This movement is converted by the mechanical transmission element (50) into the outward and upward opening of the two strap retraction arms (60, 70). In the open position, the strap retaining slots (80) are positioned above the load-bearing level of the movable main bag strap (30), allowing the shoulder straps (120) to be lifted off the ground.When the bag is lifted, the return spring (90) brings the system back to its starting position. The requested publication figure is: Figure 1.
