Abstract

A molded thermal plastic accessory cover attaching to the head assembly of a flashlight provides inwardly extending ribs to seat on the flashlight and to provide shock absorbing characteristics. A seat is provided for an auxiliary lens and the outside of the cover includes flat surfaces to inhibit rolling of the assembled cover and flashlight.

Claims

1. A cover for a flashlight, comprising

a hollow body open at each end to receive at least a portion of a flashlight therein and having an outer surface with multiple surface portions, which portions are not outwardly convex and an inner side within the hollow body;

elements extending inwardly from said inner side and being mutually displaced, said elements terminating at a surface of rotation approximating an outer surface of a portion of a flashlight to be received in said hollow body.

2. The cover of claim 7 further comprising

an inwardly extending flange at one end of said hollow body to receive an end of a flashlight positioned in said hollow body.

3. The cover of claim 2 wherein said inwardly extending flange is circular about its inner periphery and includes a first shoulder on one side thereof to receive a flashlight, a second shoulder extending inwardly from said first shoulder and an annular seat extending from a first end at said first shoulder to a second end at said second shoulder.

4. The cover of claim 3 wherein said annular seat includes means displaced from said second shoulder for retaining a lens in said annular seat abutting against said second shoulder.

5. The cover of claim 4 wherein said means for retaining a lens in said annular seat includes retainers extending inwardly from said annular seat and displaced from said second shoulder.

6. The cover of claim 1 wherein said hollow body is of substantially uniform wall thickness, said elements being of varying heights.

7. The cover of claim 6 wherein said hollow body and said elements are integrally formed.
