Abstract

An illuminated combination pad lock that illuminates in response to pressing in the combination dial or raising the shackle although still in the locked position. The illumination ceases in response to release of the combination dial or the shackle.

Claims

1. An illuminated padlock device, comprising:

a casing;

a combination dial that is rotatable about an axis of rotation;

a shackle secured within the casing and having a U-shaped portion out of the casing while the shackle is in a locked position, the shackle having play while in the locked position so as the U-shaped portion and the casing are pulled in opposite directions by an amount of the play, more of the shackle is out of the casing;

a light source secured to one of the casing and the combination dial and directed to shine light to illuminate designations on the combination dial; and

a switch secured to one of the casing and the combination dial and being responsive to relative movement of the combination dial with respect to the casing to trigger activation of the light source.

2. A device as in claim 1, the combination dial being constructed of a material selected from a group consisting of translucent plastic and transparent plastic.
