Abstract
A removable battery handle and battery casing coupling structure wherein the handle is relatively rigid and includes a central portion, and two downwardly depending arms, the distal ends of the arms each including an attachment button which is supported on the inside surface of the distal end by a shaft, the button being received by a keyhole-shaped aperture in the battery casing end wall, which offers resistance as the shaft moves from the lower, larger portion to the upper, smaller portion of the aperture such that when the shaft is disposed in the upper, smaller portion, the handle is locked to the casing.
Claims20
An electric storage battery having a detachable handle, the battery comprising:
- the handle having an elongated central portion and two arms depending from the central portion;
- each arm comprising
- a distal end opposite the central portion,
- a shaft extending from the distal end, the shafts of each arm extending generally toward each other, and
- a button disposed on the shaft;
- and
- a battery casing having end walls;
- each end wall comprising
- a recess, and
- a substantially keyhole shaped aperture opening into the recess;
- the aperture comprising
- a lower portion, the lower portion being large enough to freely receive the button,
- an upper portion, the upper portion being smaller than the button, but larger than the shaft, and
- a restriction between the lower portion and the upper portion disposed such that the restriction prohibits free movement of the shaft between the upper and lower portions, the restriction being smaller than the width of the shaft for all rotational orientations of the shaft in the aperture.
A method of attaching and detaching a substantially U-shaped handle to the end walls of an electric storage battery having a width, the method comprising the steps of:
- moving the ends of the handle apart to a distance greater than the width of the battery;
- placing the ends of the handle adjacent the substantially keyhole shaped apertures in the end walls of the battery, the keyhole shaped apertures having a larger lower portion and a smaller upper portion, each keyhole shaped aperture including a restriction between the upper and lower portions;
- moving buttons supported on shafts extending from the ends of the handle into the lower portions of the apertures in the end walls of the battery, the shafts disposed in the apertures being larger than the corresponding restrictions for all rotations of the shafts in the apertures;
- exerting an upward force on the U-shaped handle;
- advancing the shafts supporting the buttons upward within the apertures to move the shafts into the upper portions of the keyhole shaped apertures and couple the handle to the battery.
