Description

TECHNICAL FIELD The present invention relates to a door device for opening and closing an entrance of an elevator.

[Prior Art] Figs. 2 to 4 show, for example, Japanese Patent Application No. 63-
FIG. 2 is a view showing a conventional elevator door device shown in the specification of the specification and drawings, FIG. 2 is a front view of a landing door as seen from a hoistway, and FIG. 3 is a sectional view taken along line III-III of FIG. , 4th
The figure is an enlarged perspective view of a main part.

In the figure, (1) is a wall of a building, (2) is a hole which is provided in the wall (1) and communicates with a hoistway, (3) is a three-sided frame which is arranged on the inner wall of the hole (2) and forms an entrance and exit, (4 ) Is a landing door arranged on the hoistway side (front side in FIG. 2) of the three-sided frame (3),
(5) is a door hanger whose horizontal cross section is formed in a U shape, and on both sides of its lower part, a long hole (5a) along the front-rear direction of the landing door (4) is provided as a fine movement adjustment mechanism in the front-rear direction. Has been. (6) is an upper reinforcement member fixed to the upper end of the landing door (4), the inner surface (6a) of which is provided with an internal thread (6b), and both side surfaces of the door hanger (5) are provided with an upper reinforcement member (6). It is in contact with the inner surface (6a) of 6). (7) is a bolt screwed into the female screw (6b) of the upper reinforcing member (6) through the long hole (5a) of the door hanger (5), and (8) is a hanger roller attached to the upper part of the door hanger (5). 9) is a hanger case fixed to the upper wall (1) of the three-way frame (3), (10) is a door rail fixed to the hanger case (9) and guiding the horizontal hanger roller (8), and (11) is A guide leg (13) is fastened by a bolt (14), which is a lower reinforcing member laterally fixed to the lower part of the back surface of the front plate (12) of the hall door (4). (15) is a sill laid on the floor of the hall, and (16) is a steel scale for measuring the clearance between the hall door (4) and the three-sided frame (3).

The conventional elevator door device is configured as described above, and when the landing door (4) is suspended on the door rail (10) by the door hanger (5) and the hanger roller (8) and driven by a driving machine (not shown), The hanger roller (8) rolls on the door rail (10), and the hall door (4) opens and closes the doorway. At this time, the landing door (4)
The lower end of is guided by the guide legs (13) to the threshold (15).

Then, when installing the landing door (4), measure the Chilean dimensions (dimensions such as the space between the landing door (4) and the three-sided frame (3), the space between the landing doors (4), etc.) with a steel scale (16), etc. Then, after finely adjusting the door hanger (5) in the front-back direction using the elongated hole (5a) to determine the position of the landing door (4),
Tighten the bolt (7).

[Problems to be Solved by the Invention] In the conventional elevator door device as described above, since the position of the landing door (4) is adjusted by the elongated hole (5a) of the door hanger (5), the dust The dimensions must be adjusted while looking at the steel scale (16), and mutual adjustment of the landing door (4) is performed by inserting an adjustment piece between the door hanger (5) and the upper reinforcement (6). However, there is a problem in that it requires three-dimensional adjustment and the installation work time becomes long.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an elevator door installation apparatus that enables the hall door dust size to be adjusted without using a steel scale or the like.

[Means for Solving the Problem] The elevator door installation apparatus according to the present invention is one in which a block gauge is detachably mounted between a three-way frame and a landing door.

[Operation] In the present invention, since the block gauge is detachably mounted between the three-way frame and the hall door, the relative dimensions of the hall door during installation are adjusted by the block gauge, and the fine adjustment mechanism of the hall door is used. It is determined.

[Embodiment] FIG. 1 is a view showing an embodiment of the present invention.
It is a view corresponding to a cross section taken along line III-III, and portions similar to those of the conventional device are denoted by the same reference numerals. 2 and 4 are also used in this embodiment.

In the figure, (21A) and (21B) are block gauges that are attracted to the hoistway side surface of the three-sided frame (3) and are made of magnets having a predetermined dust size, and are attached to the outer surface of the front plate (12) of the landing door (4). The surface that comes into contact with the surface plate (12) is cured so as not to damage it.

In the elevator door installation device configured as described above, when adjusting the dust size of the landing door (4) during installation, the block gauges (21A) (21B) (21B) are provided on the hoistway side surface of the three-way frame (3). ) Is adsorbed and the landing door (4) is pressed against it, and the door hanger (5) and bolt (7)
Fix the landing door (4). With this, the relative dimensions of the three-way frame (3) and the landing door (4) are accurately determined.

Next, an adjusting piece is inserted between the door hanger (5) and the upper reinforcing member (6) to adjust the building of the landing doors (4) to each other. And when the adjustment of the landing door (4) is completed,
Block gauges (21A) and (21B) are removed.

[Effect of the Invention] As described above, in the present invention, since the block gauge is detachably mounted between the three-way frame and the landing door, the relative dimensions of the landing door at the time of installation are adjusted by the block gauge, and there is no three-dimensional adjustment. Only one-dimensional adjustment is required, and there is an effect that the working time can be shortened without using a steel scale or the like.

[Brief description of drawings]

FIG. 1 is a diagram showing an embodiment of an elevator door installation device according to the present invention. FIG. 2 is a sectional view taken along line III-III of FIG. 2, and FIGS. 2 to 4 show conventional elevator door devices. Fig. 2 is a front view of the landing door seen from the hoistway.
