Abstract

In the modernization of a hall display device, the number of cables connected to operating equipment may increase since the shape and the number of pushbuttons, indicators and the like are changed. In this case, it is necessary to further process a hole at the worksite for passing the cables in accordance with the number of cables, which makes the work complicated. In the present invention, a frame having an opening in the center is fixed to a hall wall, and a front plate having operating equipment is fixed in a way as to cover the opening on the hall side of the frame. A back plate having a hole for passing cables is detachably fixed in a way as to cover the opening on the elevator hoistway side.

First claim

What is claimed is:

1 . A hall operation panel for an elevator, comprising:
a frame that includes a pair of side plates and top and bottom plates each connecting ends of the side plates, thereby forming an opening, and is to be fixed to a hall wall, a size of the opening of the frame on the hall side being equal to a size of the opening of the frame on the elevator hoistway side; a front plate including operating equipment and to be fixed to the frame in a way as to cover a hall side of the opening of the frame; and a back plate having a wiring hole for passing a cable for the operating equipment to an elevator hoistway side and to be detachably fixed to the frame in a way as to cover the elevator hoistway side of the opening of the frame, wherein a position of the back plate to be fixed to the frame can be adjusted in a front-back direction of the frame while the back plate remains fixed to the frame.

2 . The hall operation panel for an elevator according to claim 1 , wherein the back plate includes fixing portions to be fixed to the top and bottom plates and a back face plate connecting the fixing portions and is formed to have a C-shaped cross section.

3 . A hall operation panel for an elevator, comprising:
a frame that includes a pair of side plates and top and bottom plates each connecting ends of the side plates, thereby forming an opening, and is to be fixed to a hall wall, a size of the opening of the frame on the hall side being equal to a size of the opening of the frame on the elevator hoistway side; a front plate including operating equipment and to be fixed to the frame in a way as to cover a hall side of the opening of the frame; and a back plate having a wiring hole for passing a cable for the operating equipment to an elevator hoistway side and to be detachably fixed to the frame in a way as to cover the elevator hoistway side of the opening of the frame, wherein the back plate is formed of three planar regions, the three planar regions include a first planar region through which the wiring hole passes, a second planar region that is perpendicular to the first planar region and has holes through which first attachment bolts are configured to pass to detachably fix the back plate to the top plate, and a third planar region that is perpendicular to the first planar region and parallel to the second planar region and has holes through which second attachment bolts are configured to pass to detachably fix the back plate to the bottom plate.
