Description

  The present invention relates to an elevator three-way frame device that constitutes an elevator hall entrance / exit.

The three-way frame device that is provided at the elevator hall and forms the entrance / exit is manufactured in accordance with specifications such as the depth dimension, material, and paint color of the three-way frame when an elevator is ordered. However, at the time of installing the three-sided frame at the construction site, the specification size on the construction side at the time of ordering and the actual size are slightly different, or the error exceeds the allowable range, and it is necessary to change the depth dimension of the three-sided frame Sometimes occurs.
In the conventional three-way frame device for an elevator, the left and right side frames and the upper frame of the three-way frame are configured so as not to expand and contract, that is, a panel having a certain frame width dimension (see, for example, Patent Document 1).
Such a conventional general three-way frame device for an elevator is configured as shown in FIGS. In the figure, 10 is an elevator floor, 11 is a building wall, 12 is a conventional three-way frame, 13 is a hall door, 14 is a hall indicator, and 15 is a hallway center line. For example, taking the left and right side frames 12 of a three-sided frame as an example, the depth of the three-sided frame is the specification at the time of elevator order by bending a single plate of metal on the front side, side, and hoistway side folding surface. Manufactured with a three-way frame dimension W based on.

JP 2003-40567 A

The conventional three-way frame device for an elevator has the following problems because the left and right side frames and the upper frame of the three-way frame are configured by a structure that cannot be expanded and contracted, that is, a panel having a certain frame width dimension. When an architectural error occurs in the building finish surface, when the three-way frame is installed, the upper frame, the left and right side frame finding surface and the building finishing surface have different steps from the specifications, thereby deteriorating the appearance. This is because the frame width dimension is determined first, so that the error of the finished building surface cannot be absorbed. In addition, when the frame width dimensions differ for floors, the design and production must be performed correspondingly, and the lot effect is reduced. In addition, the width dimension depends on the finish and structure on the construction side, so the specification decision is slow and the production period is pressed. In addition, when the frame width is slightly changed due to the change, the left and right side frames and the upper frame of the three-way frame are remanufactured. In addition, when a part of the frame panel is damaged, the entire frame panel is remanufactured, and the cost for renovation is large. Further, when the frame width dimension is large, a large amount of space is required at the time of transportation and at the installation site.
In addition, as shown in FIGS. 10 and 11, when the three-side frame is manufactured with a depth dimension W (fixed dimension), when the three-side frame is installed at the construction site, the specification dimensions and the actual dimensions at the time of receiving the order are Is slightly different, or if the error exceeds the allowable range and the depth dimension of the three-sided frame changes, the three-sided frame cannot be handled.

  The present invention was made to solve the above-described problems.At the time of installing the three-sided frame at the construction site, the specification dimensions on the construction side at the time of ordering and the actual dimensions are slightly different or there is an error. It is an object of the present invention to provide an elevator three-way frame device that can easily cope with a case where the allowable range is exceeded.

In the elevator three-way frame device according to the present invention, the upper frame of the three-way frame, which is provided in the elevator hall and forms a landing doorway, is composed of a plurality of upper frame panels that are extendable in the front-rear direction, and the front-rear direction. A left and right side frame of a three-sided frame composed of a plurality of left and right side frame panels that can be expanded and contracted, and the upper frame of the three-sided frame has a front upper frame panel that has a U-shaped section and a U-shaped section. Consists of a rear upper frame panel, and a central upper frame base panel having a U-shaped cross section provided between the rear rear side of the front upper frame panel and the rear front side of the rear upper frame panel In addition, the front upper frame panel and the rear upper frame panel are configured to be movable in the front-rear direction with respect to the central upper frame base panel, and the left and right side frames of the three-way frame have a U-shaped cross section before Left and right side frame panels and rear left and right side frame panels with a U-shaped cross section And a central left and right side frame base panel having a U-shaped cross section provided between the back side of the rear side of the front left and right side frame panel and the back side of the rear side of the left and right side frame panel. The front left and right side frame panels and the rear left and right side frame panels are configured to be movable in the front-rear direction with respect to the center left and right side frame base panel. One end of each Z-shaped reinforcement is fixed to the center of the back surface of the frame panel, and the other end of each Z-shaped reinforcement is fastened to the front and rear end portions of the center-side upper frame base panel via a slot. One end of the Z-shaped reinforcement is fixed to the center of the rear surface of the front left and right side frame panel and the center of the rear surface of the rear left and right side frame panel, respectively, and the other end of the Z-shaped reinforcement is the center side left and right side frame base panel Monodea the relative front and rear ends are attached is fastened via a long hole .

  According to this invention, when installing the three-way frame at the construction site, it is possible to easily cope with the case where the specification dimensions on the building side at the time of receiving an order are slightly different from the actual dimensions or the error exceeds the allowable range. There is an effect that can be.
