Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a door guide shoe that guides the opening and closing of an elevator door.

[Conventional technology]

A conventional door guide shoe will be explained with reference to FIGS. 1 and 2. FIG. 1 is a front view of the door, and FIG. 2 is a side view of the main part of FIG. 1.

In the figure, reference numeral 1 designates an elevator door, which is suspended from a door rail 3 by a hanging wheel 2, and whose lower end is guided by a door guide shoe 4 into a groove 6 in a sill 5, opening and closing from side to side. The door guide shoe 4 consists of a shoe 8 made of a non-metallic material such as polyurethane fixed to a mounting bracket 7 having a square cross section by baking or adhesive. Fixed at the bottom edge.

By the way, the shoe 8 opens the threshold 5 every time the door 1 is opened or closed.
Since the shoe 8 slides in the groove 6 of the door, it is prone to wear, and wear causes the door 1 to rattle and generate noise, so it is necessary to replace the shoe 8 periodically. However, in the conventional door guide shoe 4, since the shoe 8 is fixed to the mounting bracket 7, there is a problem in that the mounting bracket 7, which does not need to be replaced, must also be replaced.

In order to solve this problem, a door guide shoe as shown in FIG. 3, which is a sectional view taken along line A--A in FIG. 2, has been proposed.

In this conventional example, the mounting bracket 7 is provided with a hole 7a, and the shoe 8 is provided with a recess and a protrusion at positions corresponding to the hole 7a. The structure is such that the parts fit together. According to this configuration, since the shoe 8 can be easily attached to and removed from the mounting bracket 7, only the shoe 8 can be easily replaced.

[The problem that the idea aims to solve]

However, in the conventional guide show mentioned above, door 1
The mounting bracket 7 of the shoe 8 opens and closes when the
Sand, dirt, etc. got into the abutting end (section B in FIG. 3), and the shoe 8 sometimes peeled off from the mounting bracket 7. If the shoe 8 separates from the mounting bracket 7, the shoe 8 will hit the side surface of the groove 6, making it difficult to open and close the door 1 and causing a malfunction.

The present invention has been made for the purpose of solving the above-mentioned conventional drawbacks.

[Means and actions for solving the problem]

The present invention has an approximately L shape having a head and side parts.
The shape of the shoe is such that a pair of shoes covers the entire side surface of the mounting bracket, and the contact area between the shoes is not in the direction of movement of the door (opening/closing direction). This prevents sand, dirt, etc. from entering between the bracket and the bracket, and prevents the shoe from peeling off from the mounting bracket.

〔Example〕

An embodiment of the present invention will be described based on the drawings.
FIG. 4 shows the shoe 10 according to the present invention attached to the mounting bracket 7, and is a view corresponding to FIG. 3. Further, FIG. 5 is a perspective view of the shoe 10. The shoe 10 according to the present invention has a substantially L-shape having a side portion 10a and a head portion 10b.
A covers a side surface 7b of the mounting bracket 7 in a direction parallel to the advancing direction of the door 1, and a concave portion 11 and a convex portion 12 are provided at positions corresponding to the hole portions 7a. Also, the head 10b is connected to the door 1 of the mounting bracket 7.
covers the side surface 7c in the advancing direction of the
1 has a length equal to twice the width W2 of the side portion 10a plus the width W3 of the mounting bracket 7.

In this embodiment, as shown in FIG.
Since the abutting portions of the two are substantially perpendicular to the advancing direction of the door 1, foreign matter such as sand and dirt cannot enter, and therefore the shoe 10 can be prevented from peeling off from the mounting bracket 7. . In this embodiment, the concave portion 11 is placed close to the head 10b, and the convex portion 12 is placed far away, but this may be reversed.

FIG. 6 shows another embodiment of the present invention, in which the end of the head 10b is extended and a facing part 10c facing the side part 10a is provided, and this facing part 10c and the side part The end portion of the mounting bracket 7 is sandwiched between the recessed portion 10d formed by the mounting bracket 10a.

[Effect of idea]

As explained above, the shoe according to the present invention is approximately L-shaped having a side part and a head, and since the part where the shoes come into contact with each other is perpendicular to the direction in which the door advances, sand, dirt, etc. Since the intrusion of foreign matter can be prevented, the shoe can be prevented from peeling off from the mounting bracket.
