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 head of a flashlight, comprising

a hollow cylindrical body open at each end to receive a flashlight head and having multiple flat sides about an outer periphery thereof;

ribs extending inwardly from an inner periphery of said hollow cylindrical body, an inner extent of said ribs terminating at a surface of rotation approximating an outer surface of a flashlight head to be received in said hollow cylindrical body;

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

2. The cover of claim 1 wherein said inwardly extending flange is circular about its inner periphery and includes a first shoulder on one side thereof to receive a flashlight head, 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, said annular seat providing means displaced from said second shoulder for retaining a lens in said annular seat abutting against said second shoulder.

3. The cover of claim 2 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.

4. The cover of claim 1 wherein said hollow cylindrical body is of substantially uniform wall thickness, said ribs being of varying heights.

5. The cover of claim 1 wherein said multiple flat sides include six wide sides alternating with six narrow sides.

6. A cover for a head of a flashlight, comprising

a hollow cylindrical body open at each end to receive a flashlight head and having multiple flat sides about an outer periphery thereof, said hollow cylindrical body being of substantially uniform wall thickness;

ribs extending inwardly from an inner periphery of said hollow cylindrical body, an inner extent of said ribs terminating at a surface of rotation approximating an outer surface of a flashlight head to be received in said hollow cylindrical body said ribs being of varying heights;

an inwardly extending flange at one end of said hollow cylindrical body to receive an end of a flashlight head positioned in said hollow cylindrical body, said inwardly extending flange being circular about its inner periphery and including a first shoulder on one side thereof to receive a flashlight head, 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, said annular seat providing means displaced from said second shoulder for retaining a lens in said annular seat abutting against said second shoulder.
