Abstract

A zipper actuating device includes a first handle configured to provide an actuating force to actuate a zipper handle with a first distal end; a second distal end; and an aperture located near the first distal end configured to slide over a zipper pull tab; a second handle configured to provide a counter force to actuate the zipper with a first distal end; and a second distal end. The counter force allows the actuating force to be transferred to a bottom of the zipper handle which moves a zipper apparatus in a parallel direction to the actuating force to a set of zipper threads.

Claims (20)

1 . A zipper actuating device configured to releasably engage with a zipper having a pull tab, the zipper actuating device comprising:

a first handle having:

a first distal end;

a second distal end; and

an aperture provided on and through the first distal end, and the aperture is sized to fit the pull tab therethrough;

a second handle configured to provide a stabilizing counter force having:

a first distal end; and

a second distal end;

wherein the pull tab is sandwiched between the first handle and the second handle and passes through the aperture while in a locked position;

a flexible cord;

a fastener configured to connect the upper and lower handle to the flexible cord;

wherein the zipper actuating device is configured to allow a user to easily pull the flexible cord in an upward direction to close a zipper;

a hinge configured to connect the first handle to the second handle, the flexible cord is connected to the hinge; and

a spring connected to the hinge, the first handle, and the second handle.

2 . The zipper actuating device of claim 1 , further comprising:

a casing connecting the flexible cord to the first handle;

a spring located inside the casing;

a button located on an outside surface of the casing configured to allow the first handle to move and attach to a zipper pull tab;
