Abstract

A portable compressor of the tire in which an electrically powered compressor is housed in a case. The case having a hinged plug capable of being connected to and having fixed thereto by the connection a portable light fitting. The light fitting having permanently attached to it a length of electrical cord with a plug for temporary attachment to the cigar lighter of a vehicle to draw power from the vehicle'"'"'s electrical system. The light fitting including an outlet socket to which the hinged plug can be connected for electrical connection of the electrically powered compressor and for fixing and supporting the light fitting on the case. The hinging of the plug allowing it and the light fitting when attached to it to be folded flat to the case for storage, and the light fitting to be upstanding from the case to illuminate the region of the case. When the light fitting is removed from the plug, however, it can be used as a portable light fitting independent of the case.

Claims

1. A portable compressor of the type comprising:

an electrically powered compressor,

an air hose for the compressor,

a case housing said compressor and air hose,

a portable light fixture comprising a hand-held portion and a head portion housing the light, said hand-held portion including an outlet socket,

a length of electrical cords permanently attached to said light fixture, said length having a free end,

an electrical plug attached to said free end of said cord for connection to the electrical system of a vehicle to draw power therefrom, and

a hinged arm attached to said case and capable of folding flat within the case when the case is to be shut and being upstanding to support said portable light fixture, said hinged arm having a free end comprising an electrical plug capable of being received in said socket of the portable light fixture both to fix and support said light fixture on the end of said arm and to electrically connect said light fixture to said case.

2. A portable compressor according to claim 1 in which said electrical plugs each comprise a cylindrical shaped insulating body, a front end of said body, a resiliently depressible central contact at said front end constituting a first electrical contact, and a resiliently depressible side contact extending substantially radially out from said body to constitute a second electrical contact.

3. A portable compressor according to claim 1 in which said case is of rectangular parallelopiped shape, said compressor being permanently fitted with said case and said hinged arm being capable of being laid flat when said case is to be shut, said case having a hinged lid to protect said compressor when not in use.

4. A portable compressor of the type comprising:

an electrically powered compressor,

an air hose for the compressor,

a case housing said compressor and air hose,

a portable light fixture comprising a hand-held portion and a head portion housing the light, said hand-held portion including an outlet socket,

a length of electrical cords permanently attached to said light fixture, said length having a free end,

an electrical plug attached to said free end of said cord for connection to the electrical system of a vehicle to draw power therefrom, and

a hinged arm attached to said case and capable of folding flat within the case when the case is to be shut and being upstanding to support said portable light fixture, said hinged arm having a free end comprising an electrical plug capable of being received in said socket of the portable light fixture both to fix and support said light fixture on the end of said arm and to electrically connect said light fixture to said case,

an additional length of electrical cord wherein one end contains a socket configured to receive the plug on the end of the arm hinged to the case, and the other end contains a plug receivable in the socket of the hand-held portion of the portable light so that the light can be used remotely from the compressor while the compressor is still powered.

5. A portable compressor according to claim 4 wherein the hinged arm consists essentially of the electrical plug and a pair of integrally formed fingers receivable in complementary bearings formed in the case, the fingers and bearings cooperating to securely mount the socket to the case while permitting the socket to pivot in one direction.

6. A portable compressor according to claim 4 in which said head of said light is hinged to said hand-held portion of said light.
