Abstract

A battery adapter device for providing flexibility in the choice of batteries for powering electrical and electronic devices. The battery adapter device includes a container member having a size which is adapted to be generally equivalent to a larger conventional cell battery and being adapted to replace the larger cell battery in devices energized with larger cell batteries; and also includes a support assembly for supporting a conventional AA battery in the container member.

Claims

1. A battery adapter device for permitting a first size battery having a relatively smaller diameter to replace a second size battery having a relatively larger diameter in an electrical device, said device comprising:

a container member having a diameter size which is substantially equal to the diameter of the second size battery;

a supporting means for supporting a battery of the first size battery in an interior of said container member;

wherein said container member has a pair of end walls for each positioning adjacent to contacts of the electrical device, and a side wall extending between said end walls, an opening being formed in said side wall thereof, said opening extending substantially a length of said container between said end walls for permitting removal and reinstallation in said container member while said container member is positioned in the electrical device for accessing said supporting means such that the battery is accessible when positioned in said supporting means and said container is positioned in an electrical device.

2. A battery adapter device as described in claim 1, wherein said container member is a substantially cylindrical member having a negative terminal contact member securely disposed at one of said end walls thereof.

3. A battery adapter device as described in claim 2, wherein said negative terminal contact member is securely attached to a second said end wall of said container member and has a main portion and a battery contact portion extending from a top side of said main portion and extending in said container member and being adapted to be in contact with a battery removably disposed in said container member, said battery contact portion having a circumferentially-extending groove disposed in a wall thereof.

4. A battery adapter device as described in claim 3, wherein said second end wall has a hole centrally disposed therethrough, an edge forming said hole being located in said circumferentially-extending groove to securely retain said negative terminal contact member.

5. A battery adapter device as described in claim 4, wherein said second end wall has a recessed portion which is adapted to receive said main portion of said negative terminal contact member, said main portion of said negative terminal contact member being essentially flush with said second end wall of said container member.

6. A battery adapter device as described in claim 5, wherein said container member has a positive terminal contact member securely disposed at another end of said container member.

7. A battery adapter device as described in claim 6, wherein said supporting means includes an inner compartment defined by a cylindrical side wall which is securely disposed in said container member and being securely attached to said ends of said container member, said cylindrical side wall having an opening therethrough, said opening in said cylindrical side wall being in alignment with the opening in the container member, said inner compartment being adapted to removably receive the first size battery.

8. A battery adapter device as described in claim 7, wherein said positive terminal contact member is securely attached to a first said end wall of said container member and has a main portion, a boss-like portion centrally disposed upon extending from a top side of said main portion, and a battery contact portion extending from a bottom side of said main portion and extending in said inner compartment, said battery contact portion having a circumferentially-extending groove disposed in a wall thereof.

9. A battery adapter device as described in claim 8, wherein said container member has a first end wall having a hole centrally disposed therein, an edge of said hole of said first end wall being received in said circumferentially-extending groove of said positive terminal contact member for securely retaining said positive terminal contact member.

10. A battery adapter device as described in claim 5, wherein said supporting means includes a bore extending in said container member through a first end wall thereof and forming an inner compartment which is adapted to receive the battery therein, said battery contact portion of said negative terminal contact member being disposed in said inner compartment.

11. A battery adapter device for permitting a first size battery having a relatively smaller diameter to replace a second size battery having a relatively larger diameter in an electrical device, said device comprising:

a container member having a diameter size which is substantially equal to the diameter of the second size battery, said container member being a substantially cylindrical member having a negative terminal contact member securely disposed at one of said end walls thereof, said negative terminal contact member being securely attached to a second said end wall of said container member and having a main portion and a battery contact portion extending from a top side of said main portion and extending in said container member and being adapted to be in contact with a battery removably disposed in said container member, said battery contact portion having a circumferentially-extending groove disposed in a wall thereof, said second end wall having a hole centrally disposed therethrough, an edge forming said hole being located in said circumferentially-extending groove to securely retain said negative terminal contact member, said second end wall having a recessed portion being adapted to receive said main portion of said negative terminal contact member, said main portion of said negative terminal contact member being essentially flush with said second end wall of said container member, said container member having a positive terminal contact member securely disposed at another end of said container member;

a supporting means for supporting a battery of the first size battery in an interior of said container member, said supporting means including an inner compartment defined by a cylindrical side wall which is securely disposed in said container member and being securely attached to said ends of said container member, said cylindrical side wall having an opening therethrough;

said container member having a pair of end walls each for positioning adjacent to contacts of the electrical device, and a side wall extending between said end walls, an opening being formed in said side wall thereof, said opening extending substantially a length of said container between said end walls for permitting removal and reinstallation in said container member while said container member is positioned in the electrical device for accessing said supporting means such that the battery is accessible when positioned in said supporting means and said container is positioned in an electrical device, said opening in said cylindrical side wall being in alignment with the opening in the container member, said inner compartment being adapted to removably receive the first size battery;

said positive terminal contact member being securely attached to a first said end wall of said container member and having a main portion, a boss-like portion centrally disposed upon and extending from a top side of said main portion, and a battery contact portion extending from a bottom side of said main portion and extending in said inner compartment, said battery contact portion having a circumferentially-extending groove disposed in a wall thereof; and

said container member having a first end wall having a hole centrally disposed therein, an edge of said hole of said first end wall being received in said circumferentially-extending groove of said positive terminal contact member for securely retaining said positive terminal contact member.
