Abstract

A self-locking divider plate made of flat sheet metal is provided in an electrical box to form separate compartments. The electrical box has several upper and lower front ledges which form aligned slots which in turn, cooperate to receive the divider plate. The side edges of the divider plate has a biased sheared tab which locks the plate in place between the slots upon installation of the plate into the box. These sheared tabs extend outwardly from one of the planar surfaces of the plate. When the plate is inserted into two aligned front slots, the tabs are pushed inwardly toward the planar surface of the plate, and spring back to their normal position when the plate is in its proper position in the box. The tabs engage an inside surface of the ledges when the plate is moved outwardly from the box to prevent its accidental removal. Tangs on the back edge of the plate fit into slots in the back wall of the box, and tangs on a front edge of the plate adjacent to the sheared tabs engage the walls of the slots to position and secure the divider plate within the box.

Claims

1. An electrical box, comprising:

a body formed by a back wall, a top wall, a bottom wall, a first sidewall, a second sidewall, and a partially formed front wall,

said front wall having at least two adjacently spaced-apart ledges extending along said top wall and forming a first slot therebetween, and two adjacently spaced-apart ledges extending along said bottom wall and forming a second slot therebetween, said first slot being aligned with said second slot in a cooperative fashion, and

a removable plate slidable in said cooperating aligned first and second slots of said front wall to form compartments in said electrical box, said plate further including integrally formed self-locking means which are operated by said aligned first and second slots when said plate is slid into said first and second slots to secure said plate in said body.

2. An electrical box of claim 1, wherein said self-locking means of said plate are biasing means located along at least a side edge thereof.

10. An electrical box of claim 2, wherein said biasing means consists of a plurality of integrally formed sheared tabs which are substantially shorter than said side edge to form a recessed area between said sheared tabs and said front wall, and wherein said body further includes retainer means extending into said recessed area and associated with said sheared tabs for preventing said plate from being moved out of said front wall of said body of said electrical box.

11. An electrical box of claim 10, wherein said retainer means include sheared projections formed from said top and bottom walls of said body.

12. An electrical box of claim 2, wherein said biasing means comprises at least one sheared tab which extends parallel to a planar surface of said plate and is off-set therefrom.

13. An electrical box of claim 1, wherein said plate further comprises a front tang located along a front edge thereof and adjacent to said self-locking means;

said front tang formed to be disposed in at least one of said first and second slots of said front wall and to abut against inside surfaces thereof for preventing sideward movement of said front edge of said plate in said body of said electrical box.

14. An electrical box of claim 1, wherein said plate further comprises a rear tang located along a rear edge of said plate, and further comprising an aperture in said back wall of said body for receiving said rear tang of said plate for preventing sideward movement of said rear edge of said plate in said body.

15. An electrical box of claim 1, wherein said plate is a generally flat metal sheet.

3. An electrical box, comprising;

a body formed by a back wall, a top wall, a bottom wall, a first sidewall, a second sidewall, and a partially formed front wall,

said front wall having at least two adjacently spaced-apart ledges extending along said top wall and forming a first slot therebetween, and two adjacently spaced-apart ledges extending along said bottom wall and forming a second slot therebetween, said first slot being aligned with said second slot in a cooperative fashion, and

a removable plate slidable in said cooperating aligned first and second slots of said front wall to form compartments in said electrical box, said plate further including integrally formed self-locking means which are operated by said aligned first and second slots when said plate is slid into said first and second slot to secure said plate in said body, and wherein said self-locking means of said plate are biasing means located along at least a side edge of said plate, said biasing means including at least one integrally formed sheared tab which extends parallel to said side edge of said plate and toward a front longitudinal edge of said plate.

4. An electrical box of claim 3, wherein said at least one integrally formed sheared tab consists of a plurality of integrally formed sheared tabs which are substantially shorter than said side edge to form a recessed area between said sheared tabs and said front wall, and wherein said body further includes retainer means extending into said recessed area and associated with said sheared tabs for preventing said plate from being moved out of said front wall of said body of said electrical box.

5. An electrical box of claim 4, wherein said retainer means include sheared projections formed from said top and bottom walls of said body.

6. An electrical box of claim 3, wherein said at least one sheared tab extends parallel to a planar surface of said plate and is off-set therefrom.

7. An electrical box of claim 3, wherein said plate further comprises a front tang located along a front edge thereof and adjacent to said self-locking means;

said front tang formed to be disposed in at least one of said first and second slots of said front wall and to abut against inside surfaces thereof for preventing sideward movement of said front edge of said plate in said body of said electrical box.

8. An electrical box of claim 3, wherein said plate further comprises a rear tang located along a rear edge of said plate, and further comprising an aperture in said back wall of said body for receiving said rear tang of said plate for preventing sideward movement of said rear edge of said plate in said body.

9. An electrical box of claim 3, wherein said plate is a generally flat metal sheet.

16. An electrical box comprising:

a base wall parametrically bounded by an outer wall extending upwardly therefrom defining a box interior, said outer wall having an upper end;

a front wall disposed on said upper end of said outer wall and partially covering said box interior, said front wall defining at least one pair of aligned slots;

a plate, said plate being slidable within said aligned slots to form compartments in said box, said plate having integrally formed self-locking means for securing said plate in said box, said locking means being operable by said slots upon sliding said plate into said slots.
