Abstract

A modular faceplate assembly having a faceplate and at least one modular panel received and supported within a frontal opening in the faceplate and releasably secured to the faceplate by concealed latches hingedly connected to the modular panel rearward of the faceplate for flexure between latching and releasing positions relative to keepers carried by the faceplate and resiliently biased to said latching positions. When the latches are in latching positions latch operators carried by the latches form closures for latch operating apertures opening through the frontal surface of the faceplate assembly. Cam surfaces on the latch operators facilitate operation of the latches to release the panel from the faceplate in response to insertion of an operating tool into the latch operating apertures.

Claims

1. In a faceplate assembly including a faceplate member having a frontal opening, at least one modular insert member received and supported within the frontal opening, and latching means for releasably retaining the at least one modular insert member in assembly with the faceplate member within the frontal opening, the latching means including a concealed latch carried by the at least one insert member and a keeper carried by the faceplate member, the latch being movable between latching and releasing positions relative to the keeper, the modular insert having a forwardly open latch operating aperture for operating access to the latch, the improvement comprising a latch operator carried by said latch, said latch operator cooperating with said modular insert within said latch operating aperture to form a closure for said latch operating aperture, said latch operator being disposed within and entirely closing said latch operating aperture when said latch is in its latching position.

2. In the faceplate assembly as set forth in claim 1 the further improvement wherein said faceplate assembly defines a rearwardly open recess communicating with said latch operating aperture and said latch operator is at least partially disposed within said recess in said releasing position.

3. In the faceplate assembly as set forth in claim 2 wherein the latch operating aperture is defined by a notch in a peripheral edge of said at least one modular insert member the further improvement wherein said recess is defined by said at least one modular insert member.

4. In the faceplate assembly as set forth in claim 1 the further improvement including camming means for moving said latch from said latching position to said releasing position in response to insertion of a latch releasing tool into said latch operating aperture.

5. In the faceplate assembly as set forth in claim 4 the further improvement wherein said camming means comprises a cam surface on said latch operator.

6. In the faceplate assembly as set forth in claim 5 the further improvement wherein said cam surface is defined by a generally forwardly facing surface on said latch operator inclined rearwardly and in a direction opposite the direction of movement of said latch from said latching position to said releasing position.

7. In the faceplate assembly as set forth in claim 1 wherein the faceplate assembly includes mounting means for supporting said at least one modular insert member within said frontal opening the further improvement wherein said mounting means comprises said latching means.

8. In the faceplate assembly as set forth in claim 7 the further improvement wherein said latch operator is disposed forward of said mounting means when said latch is in said latching position.

9. In the faceplate assembly as set forth in claim 8 wherein said mounting means includes a flange on the faceplate member extending into the frontal opening and said latch is carried by said at least one modular insert member the further improvement wherein said at least one modular insert member has a recess therein communicating with said latch operating aperture and said latch operator is at least partially disposed within said recess when said latch operator is in said releasing position.

10. In the faceplate assembly as set forth in claim 8 the further improvement wherein said latch is supported on said at least one modular insert member for hinged flexure relative to said one modular insert member between said latching and releasing positions.

11. In a faceplate assembly including a faceplate having a frontal opening, a modular insert received and supported within the frontal opening, and latching means including a keeper on the faceplate an a latch supported on the modular insert for hinged flexure between latching and releasing positions relative to the keeper for releasably retaining the modular insert in assembly with the faceplate within the frontal opening, the latch being resiliently biased toward and to its latching position, the faceplate assembly having a forwardly open latch operating aperture partially defined by a notch in the modular insert for operating access to the latch member, the improvement comprising a latch operator carried by said latch, said latch operator forming a closure for said latch operating aperture, said latch operator maintaining said latch operating aperture in a substantially entirely closed condition when said latch is in its latching position.

12. In the faceplate assembly as set forth in claim 11 the further improvement wherein said modular insert defines a rearwardly open recess communicating with said latch operating aperture and said latch operator is at least partially disposed within said recess in said releasing position.

13. In the faceplate assembly as set forth in claim 12 the further improvement wherein said notch opens outwardly through a peripheral edge of said modular insert.

14. In the faceplate assembly as set forth in claim 11 the further improvement including camming means for moving said latch from said latching position to said releasing position in response to insertion of a latch releasing tool into said latch operating aperture.

15. In the faceplate assembly as set forth in claim 14 the further improvement wherein said camming means comprises a cam surface on said latch operator.

16. In the faceplate assembly as set forth in claim 15 the further improvement wherein said cam surface is defined by a generally forwardly facing surface on said latch operator inclined rearwardly and in a direction opposite the direction of movement of said latch member from said latching position to said releasing position.

17. In the faceplate assembly as set forth in claim 11 the further improvement wherein said faceplate and said modular insert are made from resilient non-metallic plastic material.

18. In the faceplate assembly as set forth in claim 17 the further improvement wherein the said faceplate and said modular insert member are of identical color.
