Abstract

A light connectable with a key, which light comprises a housing receiving the bulb and battery with which the holding of the key is achieved by a wide surface side fastening of the key handle. The light housing is formed with a shaft and the key handle is able to be pushed into the shaft of the light housing.

Claims

1. A light operating with an incandescent bulb and a battery and adapted to hold a key with a key handle, comprising

a light housing being formed with means for cooperatively receiving the incandescent bulb and the battery,

a plate,

a wide surface of the key handle being fastened planarly on said plate,

said light housing being formed with shaft means for receiving therein said plate with the key handle fastened thereon pushed into said shaft means of the light housing, said shaft means has an opening thickness corresponding to the combined thickness of said plate plus said key handle,

said plate conforming in width to that of said shaft means so that the plate can be pushed complementarily in width into the shaft means,

means for interlocking said plate with the housing in the pushed-in position,

said interlocking means comprises,

said light housing having a wall formed with an opening, and

said plate formed with at least one projection means for the interlocking of said plate with the housing, said projection means snaps resiliently into said opening of said wall of said light housing in the pushed-in position.

2. The light according to claim 1, wherein said projection means is a tongue freely cut-out from said plate.

3. The light according to claim 2, wherein

said light housing forms a rear wall of said shaft means of said light housing,

said plate has an edge abutting against said rear wall of the shaft means of said light housing in the pushed-in position.

4. The light according to claim 3, wherein

said edge is a ledge formed as a bent-off, resilient edge at en end of the plate biasing said tongue non-releaseably lockingly in said opening in the pushed-in position.

5. The light according to the claim 3, wherein

said light housing extends beyond said rear wall of said shaft means into a rear section tapering toward a free end,

a light switch button adapted to be disposed over the battery,

said rear section is formed with a reception recess, said reception recess is said means for receiving the battery as well as the light switch button,

a housing cover is releasably connected to said light housing and engages over the battery and light switch button, said housing cover forms a channel aligned in a central longitudinal plane of said light housing extending up to a mouth of said shaft means and laterally adjacent to said shaft means,

said channel in cooperation with said light housing is said means for receiving the incandescent bulb, said incandescent bulb is held in a substantially complementarily shaped front end area of the channel.

6. The light as set forth in claim 4, wherein

said plate has a flat side on which said key handle is fastened and a contour of said flat side larger than the contour of said key handle, said key handle being fastened completely within the confines of the contour of said flat side, said contour of said flat side of said plate is equal to a corresponding contour of said shaft means such that said plate is completely inserted in said shaft means in said pushed-in position and is non-twistably held therein in said pushed-in position.

7. The light as set forth in claim 6, wherein

said shaft means is formed with a widened step portion, said plate is inserted into said step portion of said shaft means, said step portion is a widest portion of said shaft means.

8. The light as set forth in claim 6, further comprising

a housing cover releaseably snappingly engaging said light housing and covering said opening of said wall of said light housing, said housing cover forms a channel laterally adjacent said shaft means, said channel in cooperation with said light housing is said means for receiving the incandescent bulb, said channel has a front open end adjacent a corresponding front open end of said shaft means, said incandescent bulb is disposed in the front open end of said channel, whereby said tongue can be removed by being pushed inwardly out of said opening to release said interlocking means from interlocking said plate with said light housing when said housing cover is removed from said light housing.

9. The light as set forth in claim 1, wherein

said plate is adhesively connected to said key handle.

10. A light having an incandescent bulb and a battery and adapted to hold a key, comprising

a light housing being formed with means for operatively receiving the incandescent bulb and the battery therein,

means for holding the key in the housing by fastening of the key handle on a wide surface thereof,

said light housing being formed with shaft means for the key handle to be pushed into said shaft means of the light housing,

a plate,

a wide surface of the key handle being fastened on said plate constituting the holding means,

said plate conforming to said shaft means so that the plate can be pushed-in complementarily into the shaft means,

means for interlocking said plate with the housing in the pushed-in position,

said light housing forms a rear wall of said shaft means of said light housing,

said plate has an edge abutting against said rear wall of the shaft means of said light housing in the pushed-in position,

said light housing extends beyond said rear wall of said shaft means into a rear section tapering toward a free end,

a light switch button adapted to be disposed over the battery,

said rear section is formed with a reception recess, said reception recess is said means for receiving the battery and the light switch button,

a housing cover engages over the battery and light switch button, said housing cover forms a channel extending up to a mouth of said shaft means,

said channel is said means for receiving the incandescent bulb, said incandescent bulb is held in a substantially complementarily shaped front end area of the channel,

said cover in a bottom area of an edge of the cover has lateral dove-tail edges, said light housing has dove-tail guides engaging with said dove-tail edges of said cover.
