Ball backlash structure used as toy, has tensile cord whose cord portions are respectively connected to ends of coupling portions which are releasably connected using safety interface

摘要

The structure has a resilient tensile cord (12) whose one end (16) is connected with a ball (10), while other end (18) of tensile cord is connected wrist fusible sleeve (14). The cord portions (12',12'') are respectively connected with the ball and fusible sleeve. The cord portions are respectively connected to ends (20',20'') of coupling portions (22',22'') which are releasably connected using safety interface (24). The ball is made of elastic material such as rubber.
