Abstract

PURPOSE:To prevent the distortion of a door plate by fitting upper and lower reinforcing members to recessed portions formed by bending both end portions of the surface plate of a riding-place door to the back side in a U-shape and installing a longitudinal reinforcing member on the back side between the upper/ lower reinforcing members via a positioning member. CONSTITUTION:Both end portions of the surface plate 3a of a riding-place door 3 are inwardly bent in a U-shape forming recessed portions 3g. Upper and lower reinforcing members 3b, 3c are fitted on the upper end and lower end of both side recessed portions 3g. Then, a longitudinal reinforcing member 3d is installed between the upper and lower reinforcing members 3b, 3c. After carrying out positioning by inserting a positioning member 11 into both recessed places 3e and 3f provided in the defined positions of the reinforcing member 3d and the lower reinforcing member 3c respectively, the longitudinal reinforcing member 3d is bonded to the back side of the surface plate 3a. When the bonding is completed, the positioning member 11 is removed. Thereby, the positioning of the longitudinal positioning member and the removal of the distortion of the surface plate can be easily performed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a door for opening and closing an entrance/exit of an elevator.

[Conventional technology]

Figures 2 and 3 are 9, e.g.
FIG. 2 is a front view of the landing door seen from the hoistway side, and FIG. 3 is a perspective view of the door.

In the diagram, (1) is the wall of the building, (2) is the entrance/exit provided in the wall (1), and (3) is the landing door located on the hoistway side (this side in Figure 2) of the entrance/exit (2). The top plate (3a) is formed by bending both side edges of the two plates, and the upper reinforcing material (3h) is glued to the upper part of the back side of the second plate (3,) and the lower reinforcing material (3h) is glued to the upper part of the back side of the second plate. (3°) and the upper and lower reinforcing members (3,), (3°) are fixed to the back side of the vertical top plate (3,) and are fixed to the back side of the vertical top plate (3,) and the upper and lower reinforcing members (3b), (3
(4) consists of vertical reinforcing members (3d) connected to the landing door (3).
Nga.

(5) is a hanger roller attached to the top of the door hanger (4), (6) is a hanger case fixed to the wall (1) above the doorway (2), and (7) is attached to the hanger case (6). The door rail (8) that is fixed and guides the horizontal hanging roller (5) is the threshold laid on the landing floor, and the door rail (9) is the door rail (9) that guides the horizontal hanging roller (5).
3) - a guide leg fixed to the upper end and guided to the sill (8);

Conventional elevator doors are constructed as shown in 1-1, and the first landing door (3) has a door hanger (4) and a hanger O-5 (5).
When suspended on the door rail (7) and driven by a drive machine (not shown), the hanger roller (5) transfers the door rail (7'), J:, and the first landing door (3) opens the entrance (2). Open and close. At this time, the lower end of the first landing door (3) is guided to the sill (8) by the guide leg (9).

[Problem to be solved by the invention]

Conventional elevator doors like the ones above have two front plates (3a
) The vertical reinforcement (36) on the back side is the upper and lower reinforcement (3,
, ), and (3c), so mutual positioning is difficult, and if warping or twisting occurs in the top plate (3a) and strain relief is performed, one top plate (3,)
There is a problem that it deforms.

This invention was made in order to solve the above-mentioned problems, and an object of the present invention is to provide an elevator door in which the positioning of vertical reinforcement members and the strain relief of the top plate can be easily performed, and the working time can be shortened. shall be.

[Means to solve the problem]

The elevator door according to the present invention has upper and lower reinforcing members and a vertical reinforcing member placed between these reinforcing members fixed to the top plate, the upper end of the vertical reinforcing member is connected to the upper reinforcing member, and the lower end is connected to the upper reinforcing member. It is disposed in a state where it is not connected to the lower reinforcing member, and a recess for inserting two positioning tools is provided in the opposing portion of the vertical reinforcing member and the lower reinforcing member.

[Effect]

In this invention, the vertical reinforcing material and the lower reinforcing material are disposed in a non-connected state, and a recess is provided in the opposing portion of the material, and a positioning tool is fitted into this, so that the vertical reinforcing material is fixed to the top plate. When doing so, positioning is performed by inserting a positioning tool into the recess.

〔Example〕

FIG. 1 is a perspective view of a door showing an embodiment of the present invention.
Components similar to those of the conventional device are designated by the same reference numerals, and FIG. 2 is also used in this embodiment.

In the figure, (3d) is the vertical reinforcement, the lower end of which is not connected to the lower reinforcement (3,), and the vertical reinforcement (3, I
) and the lower reinforcing member (3°) have recesses (3,) and (3t) cut downwards, respectively. (11) is a positioning tool that is fitted into the recesses (3,) and (3r).

In the elevator door configured as above,
When gluing the longitudinal reinforcement (34), the recess (3,).

Insert the positioning tool (11) into (3t). The longitudinal reinforcement (36) is now easily positioned and will not shift until the bonding is completed. Once the adhesion is complete, attach the positioning tool (11
) are removed. In addition, it is possible to easily remove strain caused by warping or twisting of the first top plate (31).

In addition, in the example, the first landing door (3) was explained, but
It is also applicable to cage doors.

〔Effect of the invention〕

As explained above, in this invention, the upper and lower reinforcing members and the vertical reinforcing member are fixed to the top plate 9, the vertical reinforcing member and the lower reinforcing member are in a disconnected state, and a positioning tool is inserted into the opposing part. Since the recess is provided, it is easy to position the vertical reinforcing material and remove strain from the top plate, which has the effect of shortening one working time.
