Abstract

PURPOSE:To enable a sliding door to be smoothly slid even if each groove of a doorsill and a lintel is worn out, and a lintel central part is bent by dint of load of a beam or the like or a rail is deformed otherwise, by attaching a door roller and a projection to an upper end face, and making them shiftable up and down. CONSTITUTION:The lower part of a ring plate spring 3 is attached to an upper end face, and a turning shaft 21 of a door roller 2 is set up in an upper part of this spring 3. When the door roller 2 is depressed, it is moved downward by dint of resilience of the spring 3, and when this pressing force is relaxed, it is moved upward and restored to the original state. Next, the door roller 2 is fitted in a rail 4 of a doorsill 4 and a door roller 5 in a rail 61 of a doorsill 6 at the lower end face, respectively. In this case, if these rails 41, 61 are bent to some extent due to use in a long period of time, and the central part of the doorsill is sagged downward due to load of a ceiling and suchlike, the door roller 2 goes up or down according to bending and sagging owing to the resilience of the spring 3. With this constitution, smooth sliding is made performable, and these door rollers 2, 5 are ensured on the rails 41 and 61, thus trouble is reducible.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door mounting structure.

[0002]

2. Description of the Related Art Conventionally, the sliding door mounting structure is based on the fact that it is based on Japanese Utility Model Publication No. 56.
As described in Japanese Patent No. 51182, it is attached so as to slide between a sill and a kamoi.

There are various mounting structures for the sliding upper end of the sliding door and the sliding lower end of the sliding door for the sliding door.

For example, as shown in FIG. 6, a kamoi 10
2 and the sill 101 are grooved, and convex portions 105 and 106 are provided on the upper end surface 103 and the lower end surface 104 of the sliding door, respectively.
Reference numerals 5 and 106 are the structures fitted in the grooves of the Kamoi 102 and the sill 101, and the convex portions 105, 10
When 6 slides, the sliding door slides.

As another method, as shown in FIG.
Rails 118 and 11 on the Kamoi 112 and the sill 111 respectively
7 is provided, and door wheels 115 and 116 are attached to the upper end surface 113 and the lower end surface 114 of the sliding door, and both door wheels 115 and 116 are fitted in their respective rails 118 and 117. The sliding door slides when the rails 105 and 106 slide on the rails 118 and 117.

[0006]

However, each of such sliding doors has its own problems. That is, a groove is carved in the sill and the kamoi, and a convex portion is provided on the upper end surface and the lower end surface of the sliding door, and the structure in which the convex portion is fitted into the groove of the sill or the kamoi is long-term use. When the projections and grooves are worn away, the sliding door does not slide smoothly, and when the wear becomes large, the sliding door comes off. In addition, the central portion of the Kamoi may bend downward due to the load of the ceiling, beams, etc., and the sliding door may not slide smoothly.

In the structure in which door rollers are attached to the lower end surface and the upper end surface of the sliding door and the door rollers are fitted on the rails of the sill or the Kamoi,
Grooves and ridges are less likely to wear, but rails may become uneven during long-term use, and the center of the Kamoi may bend downwards due to the load of the ceiling and beams, resulting in a smooth sliding door. I can't slip. Further, there is a problem that the door roller is easily removed.

As a result of various studies made by the present inventors on these problems, it was found that such problems can be solved by improving the structure of the upper end surface of the sliding door. Therefore, an object of the present invention is to provide a sliding door mounting structure that does not cause the above problems.
That is, it is to provide a sliding door mounting structure in which the sliding door slides smoothly and the door roller does not easily come off the rail.

[0009]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and to achieve the above objects, and has a sliding door mounting structure in which a sliding door is mounted so as to slide between a sill and a kamoi. In the above, the sliding door comprises a sliding door main body and a protrusion attached to the upper end surface of the sliding door main body so as to be movable in the vertical direction, and a groove is provided on the lower surface of the kamoi. The sliding door is slidably attached to the Kamoi.

The protrusion in the present invention is attached to the upper end surface of the sliding door body so as to be movable in the vertical direction.
In order to attach the protrusion so that it can move in the vertical direction in this way, a small piece that becomes the protrusion may be supported by an elastic body such as rubber or a spring to form the protrusion, or the protrusion itself may be manufactured using rubber or a spring. Good. In particular, if the protrusion is a leaf spring, it is easy and convenient to manufacture. Further, the mounting position of this projection may be directly mounted on the upper end surface of the sliding door body, or a convex portion may be provided on the upper end surface of the sliding door body and mounted on the upper end surface of this convex portion.

In the present invention, it is convenient to attach a rail instead of the groove provided in the Kamoi and attach a door roller instead of the protrusion attached to the sliding door because the sliding door easily slides. At this time, the door roller attached to the upper end surface of the sliding door may be attached so that the upper end surface of the door roller can move in the vertical direction.

As described above, there are various methods for attaching the upper end surface of the door roller so that the upper end surface can be moved in the vertical direction. The main methods will be described below. That is, there is a method in which a rubber tire is attached to the surface of the door roller so that the surface of the door roller moves vertically.

There is also a method in which the rotary shaft of the door roller is supported by an elastic body such as a spring or rubber and attached to the upper end of the sliding door. There is also a method in which a plate is attached to the upper end of the sliding door with an elastic body such as a spring or rubber, and the door roller is attached to the plate.

However, the structure in which the rotary shaft of the door roller is attached to the upper end portion of the sliding door via the spring is the simplest and has less troubles, which is preferable. The spring may be a spiral spring or a plate spring.

[0015]

In the method of mounting the sliding door according to the present invention, the upper end surface of the sliding door has a protrusion mounted so as to be movable in the vertical direction, and since the protrusion is fitted in the groove provided in the duck, the groove is worn. Also, even if the center of the Kamoi bends downward due to the load of the ceiling or beams, the projection moves vertically due to this wear and deflection, so the sliding door slides smoothly. ..

In addition, a rail is attached instead of the groove of the Kamoi,
If you install a door roller instead of the protrusion on the upper end surface of the sliding door and attach it so that the tip surface of this door roller can move vertically, the rail will be deformed and the center part of the kamoi will move downward due to the load such as the ceiling. Even if the door is bent, the front end surface of the door roller moves in the vertical direction, so that the sliding door slides smoothly and the door roller does not come off the rail.

If the rotary shaft of this door roller is attached to the upper end surface of the sliding door via a spring, the structure is simple and the number of failures is reduced.
