Abstract

Disclosed is a fixture plate comprising a back plate defined by a member extending in a widthwise (W) direction and a height-wise (H) direction, a plurality of support arms including a first support arm and a second support arm connecting proximate a bottom edge of the back plate and spaced in the widthwise direction by a distance W 1 , each of the plurality of support arms comprising a compound profile defining a pivot section and a support section the pivot section extending arcuately downward along the height-wise direction to a first distal end, the support section comprising a first portion forming a support base, the support base extending perpendicularly away from the back plate to a second distal end, and a second portion that forms a hook portion, the hook portion extending upwardly along the height-wise direction to a third distal end to from a free end of the support section.

First claim

What is claimed is:

1. A fixture plate, comprising,
a back plate defined by a member extending in a widthwise direction and a height-wise direction;
a plurality of support arms including a first support arm and a second support arm connecting proximate a bottom edge of the back plate and spaced in the widthwise direction by a distance W 1 ,
wherein each of the plurality of support arms comprises a compound profile defining a pivot section and a support section,
wherein the pivot section extends arcuately downward along the height-wise direction to a first distal end, and
wherein the support section comprises:
a first portion forming a support base, the support base extending perpendicularly away from the back plate to a second distal end, and
a second portion that forms a hook portion, the hook portion extending upwardly along the height-wise direction to a third distal end to from a free end of the support section; and

a plurality of sets of securing hooks including a height-wise lower set of securing hooks, the height-wise lower set of securing hooks including a first securing hook and a second securing hook widthwise aligned with the corresponding plurality of support arms and spaced height-wise by a distance H 1 above the plurality of support arms,
wherein the plurality of sets of securing hooks includes a height-wise upper set of securing hooks, the height-wise upper set of securing hooks including a third securing hook and a fourth securing hook widthwise aligned with the corresponding plurality of support arms and spaced height-wise by a distance H 2 above the plurality of support arms, wherein H 2 is greater than H 1 .

2. The fixture plate of claim 1 , comprising a service orifice for extending one or more electrical service wires through the fixture plate, the service orifice being located widthwise intermediate the plurality of support arms and height-wise proximate the height-wise lower set of securing hooks.

3. The fixture plate of claim 2 , comprising a grounding connector located widthwise intermediate the plurality of support arms, and height-wise proximate the plurality of support arms and above the service orifice.

4. The fixture plate of claim 3 , comprising a plurality of connector slots including a height-wise lower plurality of connector slots, the height-wise lower plurality of connector slots including a first connector slot and a second connector slot, the height-wise lower plurality of connector slots being widthwise symmetrically distributed between the plurality of support arms and height-wise intermediate the plurality of support arms and the height-wise lower set of securing hooks.

5. The fixture plate of claim 4 , wherein the plurality of connector slots includes a height-wise upper connector slot widthwise intermediate the plurality of support arms and height-wise proximate the height-wise upper set of securing hooks.

6. The fixture plate of claim 5 , comprising a support bracket, widthwise intermediate the plurality of support arms and height wise proximate the support base of the support section of the plurality of support arms.

7. The fixture plate of claim 6 , wherein the support bracket contains a notch for receiving a connector.

8. A housing supported by the fixture plate of claim 7 , the housing comprising a back surface with a plurality of sets of slots, including:
a plurality of sets of support arm slots including a first set of support arm slots and a second set of support arm slots, the plurality of sets of support arm slots being widthwise spaced on the back surface for pivotally engaging the corresponding plurality of support arms of the fixture plate.

9. The housing of claim 8 , wherein each set of support arm slots includes:
a plurality of slot openings including a first slot opening and a second slot opening, the plurality of slot openings being height-wise adjacent, the first slot opening being height-wise below the second slot opening with a first cavity formed therebetween within the housing,
wherein a surface portion, between the plurality of slot openings, forms a pivot support brace.

10. The housing of claim 9 , wherein when the housing pivoted away from the fixture plate,
the plurality of support arms engages the corresponding plurality of sets of support arm slots so that the pivot section extends into the first slot opening, the support base of the support section is against the pivot support brace, and the hook portion of the support section extends through the second slot opening to restrain motion of the housing that is perpendicular to the back plate, and
a bottom edge of the back surface of the housing is against the bottom edge of the fixture plate and the back surface of the housing is substantially perpendicular to the back plate of the fixture plate,
whereby the housing is supported by the fixture plate and the housing is prevented from pivoting further away from the from the fixture plate.

11. The housing of claim 10 , wherein the plurality of sets of slots includes
a plurality of sets of securing slots including a lower set of securing slots and an upper set of securing slots, the plurality of sets of securing slots being height-wise spaced on the back surface for pivotally receiving the corresponding plurality of sets of securing hooks of the fixture plate.

12. The housing of claim 11 , comprising a second cavity which may be a service cavity for pivotally enclosing the service orifice, a grounding connector and the height-wise lower plurality of connector slots and the support bracket of the fixture plate.

13. The housing of claim 12 , wherein the service cavity includes a bottom surface that includes a connector slot opening through which connector extends to engage the notch in the support bracket of the fixture plate.

14. The housing of claim 13 , wherein the service cavity includes a front surface and a top surface, at least one of which having a service aperture for receiving the one or more electrical service wires from the service orifice in the fixture plate.

15. The housing of claim 8 , comprising an upper slot for pivotally engaging the height-wise upper connector slot of the fixture plate.

16. The housing of claim 8 , wherein the housing is plastic.

17. The housing of claim 8 , wherein the housing encloses therein a controller for an elevator.

18. The fixture plate of claim 1 , wherein the fixture plate is metal.
