Description

  The present invention relates to an elevator car operation panel equipped with a switch box having a cover that opens and closes the entire surface in the lateral direction by rotation of a hinge.

  An upper panel that mounts a push button, a switch box that houses a maintenance switch, a lower panel that is installed under the switch box, and an upper panel, a switch box, and a lower panel that are arranged in pairs at both ends, In an elevator car operation panel composed of a reinforcing plate that integrates these, and a case that houses the integrated upper panel, switch box, and lower panel, the switch box must be closed during normal elevator use. There is a need for a switch box cover that can be maintained and opened when the switch inside the switch box is operated. In the elevator car operation panel, in order to improve its design, it is desirable that the switch box cover has a structure that can be fully opened and closed to reduce the number of notch lines appearing on the surface of the car operation panel.

  For example, the switch box includes a switch box cover, an upper hinge and a lower hinge for rotating the switch box cover, and a cover lock for keeping the switch box cover closed. In the switch box configured as described above, the rotation axis side of the switch box cover, that is, the axis side formed by connecting the upper hinge and the lower hinge enters the switch box in accordance with the opening operation of the switch box cover. . At this time, the rotating shaft side of the reinforcing plate is cut so that the switch box cover and the reinforcing plate do not interfere with each other. Further, during normal use of the elevator, the cover lock is locked to the cover plate so that the switch box cover is kept closed. On the other hand, when opening the switch box cover, the cover lock is operated with a key to release the engagement with the cover plate. Note that if the cover lock is loosely locked on the cover plate, the switch box cover will rattle. In order to prevent this, it is necessary to set the cover lock to the cover plate relatively tightly. There are the following switch boxes for an elevator car operation panel (see, for example, Patent Document 1).
