Pedastal closure assembly having snag-free lock
View Patent ↗A quarter turn slide lock assembly having a base, a cover, a slider, a rotator, springs and washers. The base includes a channel for the slider to move between extended and retracted positions. The slider includes internal and exterior cam follower surfaces. The rotator has a hex head for 90° rotation by a special tool and a cam arm for engaging the internal cam follower surface of the slider. The external cam follower surface is biased by an abutting surface on an object to be locked and the springs bias the slider in an opposite direction to an interference fit with the object. The base includes a smooth, slanted outer surface to avoid snags and the washers reinforce the slide lock so that rivets used to attach the slide lock to an object to be locked are strongly secured. The cover snap fits to the base for a simple and reliable slide lock assembly.

a base connected to an interior portion of a dome of said pedestal closure, said base having a channel formed therein and an outer surface free of sharp edges;
a slider mounted in said channel of said base and movable along said channel between an extended position and a retracted position;
a rotator mounted to said base and connected to said slider for moving said slider to its retracted position;
drainage ports in communication with said channel; and
a biasing element mounted between said base and said slider for pushing said slider to said extended position.
2. The assembly as claimed in claim 1 wherein:
said slider includes a cam follower wall and a cam follower surface for engaging said rotator.
3. The assembly as claimed in claim 1 wherein:
said rotator includes a body and an arm, said arm for acting as a cam when said body is rotated.
4. The assembly as claimed in claim 1 wherein:
said outer surface includes a smooth, slanted surface.
5. The assembly as claimed in claim 1 wherein:
said base includes an opening for receiving said rotator and a side wall; and said slider includes an elongated slot for receiving said rotator and an abutment wall.
6. The assembly as claimed in claim 5 including:
a cover, said cover having an opening for said rotator.
7. The assembly as claimed in claim 6 wherein:
said cover includes a snap arm for engaging said base; and said base includes a snap arm receiving opening.
8. The assembly as claimed in claim 7 wherein:
said biasing element is a compression spring mounted between said side wall of said base and said abutment wall of said slider.
9. The assembly of claim 1 wherein the outer surface includes a plurality of slanted surfaces.
10. The assembly of claim 9 wherein the plurality of slanted surfaces includes an upper surface and a lower surface.
11. The assembly of claim 10 wherein the plurality of slanted surfaces further includes at least two side walls.
12. The assembly of claim 11 wherein the outer surface further includes at least one rounded intersection.
13. The assembly of claim 12 wherein the outer surface further includes at least one rounded corner.
14. A pedestal closure assembly comprising:
a dome having a lower portion, an assembly base, and a lock, the lock including an interior portion positioned on an interior portion of the dome and adjacent cables when the cables are installed in the pedestal closure assembly, wherein the dome is configured to slide onto the assembly base, wherein said interior portion of the lock includes a snag-free lock base housing additional lock parts for securing the dome to the assembly base, and wherein the snag-free lock base is free of sharp edges so as to avoid snagging the cables when the dome is removed from or installed on the assembly base with the cables installed in the pedestal closure assembly.
15. The pedestal closure assembly of claim 14 wherein the snag-free lock base includes a plurality of slanted surfaces.
16. The pedestal closure assembly of claim 15 wherein the plurality of slanted surfaces includes an upper surface and a lower surface.
17. The pedestal closure assembly of claim 16 wherein the plurality of slanted surfaces further includes at least two side walls.
18. The pedestal closure assembly of claim 17 wherein the snag-free lock base further includes at least one rounded intersection.
19. The pedestal closure assembly of claim 18 wherein the snag-free lock base further includes at least one rounded corner.
20. The pedestal closure assembly of claim 14 further comprising a mounting plate for supporting cables.
21. The pedestal closure assembly of claim 20 wherein the snag-free lock base is positioned in close proximity to the mounting plate when the dome is removed from or installed on the assembly base.
22. The pedestal closure assembly of claim 21 wherein the lock is positioned on the lower portion of the dome.
