Description

  The present invention relates to an elevator hall entrance / exit device, and more particularly to an installation structure of a screen manual closing device in an elevator hall entrance / exit device.

  In the prior art, there has been a simplified manual operation device for releasing a brake in an architectural shutter installed in a building opening or the like by reducing the number of parts of the device (for example, see Patent Document 1). ).

JP-A-9-324590

In a manual operation device for releasing a brake in an architectural shutter according to the prior art, the manual operation device is an operation embedded in a building frame together with a push button type operation switch for opening, stopping and closing the shutter curtain. The structure is arranged in the box, and the part facing the push button of the operation switch is opened to open the window, so that the push operation (the push operation for the brake release operation can be performed).
In other words, the operation box is embedded in the wall of the building, and it is necessary to consider the connection with the wall and the setup for embedding, so that the installation cost increases, the connection of the wire to the manual operation device and its protection However, there is a problem that a new window is required after the push button operation.

A screen manual closing device is fitted and integrated in the vertical frame, which is a component part of a smoke-shielding / flame-proofing screen built-in type three-frame frame equivalent to a shutter curtain in the prior art, and the screen manual closing device and smoke shielding / shielding are integrated. Although it is conceivable to connect the flame screen device with a pipe to protect the manual closing wire from mortar for architectural finishing, etc., this method requires a manufacturing cost because the pipe cannot be manufactured by bending the steel plate in the same manner as the three-side frame manufacturing.
Also, when the three-way frame is assembled and shipped at the factory, the building finish is mortar-less. In such a case, there was a problem that the installation cost was increased such as arranging a new pipe.

  The present invention aims to simplify the installation structure of the manual closing device and to obtain an elevator landing doorway device that can appropriately manufacture a protective cover for the manual closing wire by the same bending process as the frame member and can reduce the cost. To do.

  In the elevator hall entrance / exit device according to the present invention, a screen device for forming smoke shield and flame shield at the elevator hall entrance / exit by being incorporated in a frame member formed by bending a plate-like member and installed at the elevator hall entrance / exit A manual closing device for closing the screen device via a manual closing wire, and formed by bending a plate-like member so as to surround the manual closing wire. A protective cover is provided which extends in between and protects the manual closing wire.

  According to this invention, while simplifying the installation structure about a manual closing device, the protective cover of a manual closing wire can be appropriately manufactured by the bending process similar to a frame member, and the elevator landing doorway apparatus which can suppress cost can be obtained. be able to.
