Abstract

A battery storage compartment for selectively storing cylindrical batteries, such as dry cell batteries, or another battery of the type having a non-cylindrical end and a length different from that of said cylindrical batteries, such as a rechargeable battery. The battery storage compartment comprises a compartment member, spring means secured to one end wall of the compartment member, electrically conductive means located at the opposite end wall of the compartment and an abutment member attached to the compartment member at a location intermediate the opposite end walls and projecting from the bottom of the compartment member. The abutment member has cutout portions to accommodate the cylindrical dry cell batteries and spaced ribs which project toward the opposite end wall of the compartment member. When a rechargeable battery is placed in the storage compartment it is situated between the abutment member and the spring means.

Claims

1. A battery storage compartment for selectively storing cylindrical batteries or another battery of the type having a non-cylindrical end and a length different from that of said cylindrical batteries, said battery storage compartment comprising:

a compartment member having first and second opposite end walls and a bottom portion interposed therebetween;

electrically conductive spring means secured to said first end wall and extending toward said second end wall;

electrically conductive means located at said second end wall; and

an abutment member attached to said compartment member projecting from said bottom portion at a location intermediate said first and second end walls and extending in a direction parallel thereto, said abutment member having a cutout portion therein and spaced rib members extending toward said second end wall;

said cylindrical batteries, when stored, fitting within the cutout portions of said abutment member and between said spaced rib members in electrical contact with said spring means, said cylindrical batteries being urged by said spring means toward said electrically conductive means;

said another battery, when stored, having its non-cylindrical end supported by said abutment means and its other end electrically connected to said spring means, said another battery being urged by said spring means and toward said abutment means.

2. A battery storage compartment according to claim 1, wherein said abutment member is integrally formed with the bottom of said compartment member.

3. A battery storage compartment according to claim 1, wherein the cutout portion in said abutment member defines at least one arcuate opening substantially conforming with the external circumference of cylindrical batteries stored in said storage compartment.

4. A battery storage compartment according to claim 3, wherein said compartment member accommodates the storage of at least two parallel rows of cylindrical batteries, and said abutment member has two of said arcuate openings therethrough for conforming to the external circumferences of said cylindrical batteries stored therein in said rows to permit said batteries to pass through said openings without interference.

5. A battery storage compartment according to claim 4, wherein said rib member is attached to said abutment member between the arcuate openings therein and extends parallel to the axes of the cylindrical batteries stored in said compartment member.

6. A battery storage compartment according to claim 5 wherein the distance between said first and second end walls is substantially equal to the axial length of an integral number of cylindrical batteries and the distance between said first end wall and said abutment member is substantially equal to the length of said another battery, the cutout portion of said abutment member being smaller than the end dimension of said another battery to permit said another battery to be supported between said abutment member and said first end wall.

7. A battery storage compartment according to claim 6, wherein said abutment member is integrally formed with said bottom of said compartment member.

8. A battery storage compartment according to claim 6 wherein said cylindrical batteries are dry cell batteries and said another battery is a rechargeable battery pack.

9. A battery storage compartment according to claim 1 wherein said electrically conductive means includes conductive terminals for contacting said cylindrical batteries, when stored, and a terminal member for making an electrical connection to said another battery, when stored.

10. A battery storage compartment according to claim 1 which further comprises means attached to said first end wall for retaining said cylindrical batteries or said another battery within said compartment member.
