Abstract
The ball bearing post and quick release system with revolute joint, and its movement limiter makes the use of the jump rope more convenient and safer for the user. The presented solution includes a clevis with a movement limiter in the ball bearing post and a tang in the quick release system joined together with a fastening element, and together forming a revolute joint. The movement limiter prevents movement of the quick release system to the extent that the quick release system cannot move against user's hand, or against the ball bearing housing located at the top of the jump rope handle.

A revolute joint configured to connect a jumping rope cable and a jumping rope handle having a ball bearing in a ball bearing housing, wherein the revolute joint comprises:
- a cable connector configured to detachably receive one end of the jumping rope cable;
- a quick release system configured to release the cable connector;
- a ball bearing post comprising a cylindrical part configured to be attached to the ball bearing inside the ball bearing housing in the jumping rope handle and a substantially U-shaped clevis, sides of which form two fastening members each having a hole to receive a fastening element, and a recess in bottom of the U-shaped clevis;
- a substantially T-shaped movement limiter having a wide upper part and a narrow lower part, and being configured to fit into the U-shaped clevis such that the narrow lower part is supported by a bottom of the recess, and ends of the wide upper part are configured to protrude into two opposite directions outside of space between the fastening members,
- and wherein
- the cable connector is a cylindrical tube having an open first end configured to receive the end of the jump rope cable, and a second end attached to a first end of the quick releases system;
- the quick release system comprising a tang in a second end,
- the tang having a tang opening and the tang configured to fit into the space between the fastening members of the U-shaped clevis above the movement limiter, and being attached between the two fastening members by the fastening element penetrating the holes of the two fastening members and the hole of the tang;
- wherein protruding ends of the movement limiter are configured to limit movement of the quick release system by preventing the quick release system from touching the ball bearing housing.
