Abstract

PURPOSE:To display a three-dimensional appearance on the surface of an entrance door, and to expand the scope of designing expression, by forming the form of longitudinal section of the entrance door in an uneven form. CONSTITUTION:Since the form of the longitudinal section of the front plate la of an entrance door 1 is made in an uneven form, a three-dimensional feeling is given to the entrance door 1. As a result, the entrance door 1 liable to give a plain and monotonous feeling conventionally increases a grave looking, and gives a novel designing feeling. And the entrance 2a of a three way frame 2 is also formed responding to the form of the longitudinal section of the front plate la, and the entrance door 1 can be opened and closed. And since the gap is even and at the necessary minimum, the appearance is good enough, and furthermore, a hand or a substance can be hardly caught in the gap, and the safety of passengers is secured, consequently.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator door device provided at an entrance/exit, and particularly relates to the design of a landing door.

[Prior Art] As a conventional elevator door device, there is one shown in FIGS. 2 to 4.

Figure 2 is a front view showing a conventional elevator door device;
The figure is a cross-sectional view of FIG. 2, and FIG. 4 is a longitudinal cross-sectional view of FIG. 2.

In the figure, (1) is a landing door provided at the entrance/exit of the landing, and the main body is composed of - - flat plate-shaped top plates (1a). The surface of the top plate (1a) that can be seen from the front is subjected to various surface treatments such as painting, pear-finishing, and finishing, or by changing the quality of the abrasive material to improve its appearance. ing. (2) is a three-sided frame fixed around the entrance/exit of the landing, (3) is the landing floor, and (4) is the landing floor (3).
A sill attached to the side edge of the hoistway (5), (4a) is a guide groove formed in the sill (4), and (6) is a guide projecting downward from the lower end surface of the landing door (1). With a shoe,
It is fitted into the guide groove (4a) of the threshold (4) to guide the opening and closing movement of the landing door (1). (7) is a landing wall, and (8) is a landing button attached to the wall (7). (9) is a hanger plate 1 fixed to the two end faces of the landing door (1), (10) is a guide roller pivotally attached to the hanger plate (9), and (11-) is the doorway of the landing. -1; The guide roller (10) is movably supported by a guide rail installed in the section.

(12) is a hanger poop that covers the hanger play 1-(9), the guide roller (10), and the guide rail (11).

Note that the door (1) is, for example, disclosed in Japanese Unexamined Patent Application Publication No. 1972-1999.
There is also a double-structured structure in which a reinforcing member is interposed between the front plate and the back plate, such as the technology published in Publication No. 6.

Next, the operation of the conventional elevator door device configured as described above will be explained.

When the elevator car (not shown) arrives at the landing, the landing door (1) is opened in conjunction with the elevator car door (not shown).
is opened and closed. At this time, the guide roller (10) provided at the top of the landing door (1-) is connected to the guide rail (11).
The guide shoe (6) provided at the lower end is guided by the guide groove (4a) of the sill (4), thereby stably running.

[Problem to be solved by the invention] The conventional elevator door device is configured as described above,
Since the top plate (1a) of the landing door (1) is formed in a flat shape, the only way to improve the exterior design is to change the grain quality or devise a surface finish. 1- The range of means was narrow and limited.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an elevator door device that can further improve the exterior design by increasing the degree of freedom in designing the exterior design of the hall door.

[Means for Solving the Problems] In the elevator door device according to the present invention, the vertical cross-sectional shape of the landing door is formed into an uneven shape, and the landing door is configured to be used for entering and exiting in a three-sided frame provided around the landing door. The entrance/exit portion is formed to match the vertical cross-sectional shape of the landing door.

[Function] In the present invention, by forming the vertical cross-sectional shape of the landing door into an uneven shape, three-dimensional expression can be made on the surface of the landing door, and the range of design expression can be expanded.

[Example] An embodiment of the present invention will be described below with reference to FIG.

FIG. 1 is a longitudinal sectional view showing an elevator door device according to an embodiment of the present invention. In the drawings, the same reference numerals as in FIGS. 2 to 4 indicate parts that are the same as or correspond to conventional components.

In the figure, (1,) is a landing door, and the vertical cross-sectional shape of the top plate (1a) is formed in an uneven shape.

(2) is a three-sided frame, and an entrance/exit portion (2a) through which the landing door (1-) enters and exits is formed in an uneven shape to match the shape of the top plate (1a) of the landing door (1). In other words, the landing door (
1) is formed so that there is no interference when opening and closing, and the gap between the front plate (1a) of the landing door (1) and the entrance/exit part (2a) is uniform and the minimum necessary size. .

Next, the operation of the elevator door device of this embodiment configured as described in -1- will be explained.

Since the vertical cross-sectional shape of the front plate (1a) of the landing door (1-) is formed in an uneven shape, the landing door jj? (1) gives a three-dimensional effect. Therefore, it is possible to give the hall door (1), which has conventionally tended to be flat and monotonous, an innovative design feeling with added solidity.

In addition, the entrance/exit part (2a) of the three-sided frame (2) is also the landing door (1).
By matching the vertical cross-sectional shape of the top plate (1a), the landing door (1-) can be opened and closed, and the uniform and minimum gap provides a good appearance. Since it is almost impossible to insert hands or objects, the safety of passengers is ensured.

The landing door (1-) can further emphasize the three-dimensional effect by using the shadows of light from the illumination lights, and can also create a different image. and,
A variety of designs can be created by combining the grain quality and surface finish.

Thus, in the elevator door device of the above embodiment, the vertical cross-sectional shape of the hall door (1) is formed into an uneven shape, and the three-sided frame (2) provided around the hall door (1) has the An entrance/exit portion (2a) through which the landing door (2) enters and exits is formed to match the vertical cross-sectional shape of the landing door (1).

Therefore, according to the embodiment described above, it is possible to create a three-dimensional expression on the surface of the landing door (1), thereby increasing the solidity and expanding the range of design expression. This makes it possible to respond to diversifying customer needs.

By the way, the landing door (1) of the above embodiment has one front plate (
1a), when carrying out the present invention, the present invention is not limited to this, and the method using JP-A-H]
It is clear that the present invention can also be applied to a double-structure structure consisting of a front plate and a back plate, as disclosed in Japanese Patent No. 1-97296. In this case, the back plate may be either 5F surface or three-dimensional.

Further, although the vertical cross-sectional shape of the front plate (1a) of the landing door (1) in the above embodiment has unevenness formed in straight lines, the present invention is not limited to this. , a curved line or a combination of a straight line and a curved line.

Effects of the Invention As described above, in the elevator door device of the present invention, the vertical cross-sectional shape of the hall door is formed into an uneven shape, and the hall door is arranged in a three-sided frame provided around the hall door to allow entry and exit. The entrance/exit portion is formed to match the vertical cross-sectional shape of the landing door. Therefore, it is possible to create a three-dimensional expression on the surface of the landing door, increasing its solidity and expanding the range of design expression. This makes it possible to respond to diversifying customer needs.
