Abstract

A bar-shaped lamp having a battery housing in the form of a shaft with a lamp head removably attached at one end and provided with one or more light-emitting diodes. At the other end a reversible foot member can be inserted into the shaft and has a ground spike and an impact tool for breaking automobile glass on opposite sides. When the short tool projects from the shaft, it can be covered by a cap.

Claims (19)

1. A bar-shaped lamp comprising:

an elongated shaft;

a lamp head affixed to one end of said shaft and comprising a plate, a plurality of light-emitting diodes mounted on said plate and a spiral contact spring resiliently engageable with a battery in said shaft;

a reversible elongated foot member receivable in said shaft at an opposite end of said shaft and having at a first end of said foot member an elongated conical spike adapted to be inserted into the ground and at a second end of said foot member a conical impact tool capable of rupturing a vehicle window, said spike and said tool having respective apex angles with the apex angle of said spike being less than the apex angle of said tool, said foot member having a portion between said spike and said tool which is flush with said shaft and adapted to be inserted into said shaft;

a threaded connection replaceably securing said lamp head on said shaft;

a plate, a plurality of light-emitting diodes mounted on said plate and a spiral contact spring resiliently engageable with a battery in said shaft; and

a cap adapted to receive said tool and threaded onto said foot member.

2. The bar shaped lamp defined in claim 1 , further comprising an elongated light-transmitting body affixed to said head and illuminatable thereby.

3. The bar-shaped lamp defined in claim 2 wherein said body is a rod of a light-conducting plastic.

4. The bar-shaped lamp defined in claim 3 wherein said rod is composed of polymethylmethacrylate and is threadedly connected to said shaft.

5. The bar-shaped lamp defined in claim 1 wherein said shaft comprises a battery holder and a compartment dimensioned to receive said spike.

6. A bar-shaped lamp comprising:

an elongated shaft;

a lamp head affixed to one end of said shaft and provided with a light source;

a reversible elongated foot member receivable in said shaft at an opposite end of said shaft and having at a first end of said foot member an elongated spike adapted to be inserted into the ground and at a second end of said foot member an impact tool capable of rupturing a vehicle window, said shaft comprising a battery holder and a compartment dimensioned to receive said spike; and

a cap adapted to receive said tool and threaded onto said foot member.

7. The bar-shaped lamp defined in claim 6 , further comprising an elongated light-transmitting of an acrylic resin body affixed to said head and illuminatable thereby.

8. The bar-shaped lamp defined in claim 7 wherein said lamp head comprises a plate, a plurality of light-emitting diodes mounted on said plate and a spiral contact spring resiliently engageable with a battery in said shaft.

9. The bar-shaped lamp defined in claim 8 wherein said foot member has a portion between said spike and said tool which is flush with said shaft and adapted to be inserted into said shaft.
