Abstract

PROBLEM TO BE SOLVED: To stop a main body at an optional position by arranging a stopper in the opening direction at the position where the main body is moved on a rail, shaft-fitting and suspending the stopper in the direction along the travel of the main body, and bringing the side edge of the stopper into contact with the upper face of the rail. SOLUTION: When a main body 1 is set to the closed state, a stopper 4 is set to the inclined state to the backward direction of the main body 1. When the traveling force is applied in the opening direction to the main body 1, the stopper 4 is rotated centering on a shaft-fitting section 5 by the friction with a rail 2, and it is traveled in the opening direction in the inclined state to the forward direction of the main body 1. Since the stopper 4 is inclined to the forward direction, its travel is stopped by the friction with the rail 2 when the force in the opening direction is released, and the opened state of the main body 1 is maintained. When force is applied in the closing direction, the stopper 4 is rotated by the friction with the rail 2 into the inclined state to the backward direction of the main body 1, and the stopper 4 is traveled in the closing direction to close an opening section. The travel of the main body 1 in the closing direction can be automatically stopped.

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a free stopper for a self-closing sliding door which can stop a sliding door having a function of automatically closing at any position.

[0002]

2. Description of the Related Art Generally, there is a sliding door having a function of automatically running in a closing direction when left in an open state in order to always obtain a closed state. However, even with a sliding door having such a function, there may be a situation where it is desired to stop the door in the open state. In this situation, some obstacle in the sliding door was used to prevent the movement in the self-closing direction. Is normal.

By the way, such a self-closing prevention method has the disadvantage that the work of each time is complicated and the sliding door is automatically closed due to the removal of the obstacle.

[0004] Therefore, conventionally, it has been found that a rail is mounted on a rail on which a sliding door travels, and a device for elastically pressing a stopper to stop it at an arbitrary position is incorporated into the rail, but the mechanism and structure are complicated and expensive. Not only when the door is stopped, but also when the sliding door is closed as well as when the door is stopped in the open state, it is necessary to operate the stopper each time, which is extremely troublesome.

For this reason, the advent of a free stopper that has a simple mechanism and structure, can be manufactured at low cost, and is easy to open and close the sliding door is desired. An eccentric roller is mounted on the rail on which the sliding door travels by the force of a spring. Although a method of elastic pressure was considered, elastic pressure operation is indispensable to elastically press the eccentric roller to the traveling rail, and when the sliding door is moved in the closing direction, rotation of the eccentric roller causes the traveling rail to move. It required a complicated mechanism and structure to automatically release the elastic pressure of the eccentric roller, and it was inevitably more expensive than the conventional product.

[0006]

The problems to be solved are not only the mechanism and structure of the conventional apparatus are complicated and expensive, but also the operation for stopping at an arbitrary position or the stop state is required. The operation for releasing and the complicated mechanism for releasing were essential.

DISCLOSURE OF THE INVENTION The present invention relates to a sliding door main body which is automatically closed by running a rail in a closing direction from an opened state, and a sliding door above a rail or an auxiliary rail parallel to the rail. A stopper having a large friction coefficient and having a lower edge and at least one side edge formed in an arc shape at a location that moves together with the main body is arranged with the arc shape of the side edge in the opening side direction of the sliding door body, and the sliding door. The main body is hung so as to be swingable in the direction along which the main body travels, and the stopper is slanted with respect to the upper surface of the rail or the auxiliary rail so that the arcuate side edge is in contact.

The stopper may have a teardrop shape or a fan shape in which the diameter of the lower half is formed to be large and symmetrical.

A rail with which the stopper contacts in an inclined manner,
Alternatively, it is preferable that the auxiliary rail is provided with a gap or a concave portion that brings the stopper into a vertical state when the sliding door body is closed.

Further, there is also a configuration in which the stopper is hung on a support body that moves up and down with respect to the sliding door body and holds its position by the operation of an operating portion provided on the sliding door body.

[0011]

The stopper is formed such that the length from the shaft mounting portion to the lower edge portion is longer than the length from the shaft mounting portion to the rail or the upper surface of the auxiliary rail provided in parallel with the rail. , It is normal to contact the rail or the upper surface of the auxiliary rail in a state inclining in the direction opposite to the running of the sliding door body, and when the sliding door body is closed, the stopper is the rearward direction of the sliding door body. It is in a state of tilting to (Fig. 6, Fig. 10, first operation).

From this state, when a force is applied to the sliding door body to move it in the opening direction, the stopper rotates about the shaft attachment portion against the elasticity of the stopper due to the friction with the rail or the auxiliary rail (see FIG. 7). , FIG. 11, second operation), and the state in which the stopper is inclined in the direction opposite to the traveling of the sliding door body, that is, the front direction of the sliding door body (FIG. 8,
In FIG. 12, third operation), the sliding door body runs in the opening direction in this state.

When the force in the opening direction is released, the sliding door body automatically starts running in the closing direction.
Since the stopper is inclined in the front direction, which is the traveling direction of the sliding door body, the sliding door body is stopped from traveling due to friction with the rail or the auxiliary rail (FIG. 9, FIG. 13, fourth operation). The body remains open.

In order to close the sliding door main body from the opened state, a force in the closing direction is applied to the sliding door main body to resist the elasticity of the stopper stopped by the friction with the rail or the auxiliary rail, and the shaft is attached. Rotate around the part, the direction opposite to the running of the sliding door body, that is,
With the stopper tilted to the rear of the sliding door body,
With the stopper kept in this state, the sliding door body travels in the closing direction to close the opening (FIG. 6, FIG. 1).
0, first operation).

Further, when the rail or the auxiliary rail is provided with a gap or a recess in which the stopper is in a vertical state when the sliding door body is closed, the stopper automatically hangs down in the gap or the recess. This is the case (states shown in FIGS. 2 and 4).

Further, when the stopper is suspended from a support body which is vertically movable with respect to the sliding door body, the support body may be operated up and down to operate an operation portion for holding the position. It is possible to contact and separate the stopper rail or auxiliary rail.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 is a sliding door main body, which is suspended on a rail 2 inclined toward a closing side end mounted above an opening and automatically closed. It is structured to be.

Reference numeral 3 denotes a support body which is arranged above the rail 2 and is attached to a portion which moves together with the sliding door body 1. The support body 3 is made of an elastic material such as rubber or has a spring or the like. A stopper 4 having a large friction coefficient, which is provided with elasticity by being incorporated therein, is pivotally mounted 5 so as to be swingable in the direction along which the sliding door body 1 travels, and contacts the upper surface of the rail 2 in an inclined manner. Since it is suspended, the stopper 4 has a lower edge and a semicircular shape in which at least one side edge is formed in an arc shape, or a crescent shape, and the length from the shaft attachment portion to the lower edge portion is the axis. The length is longer than the length from the attachment portion to the rail or the upper surface of the auxiliary rail provided in parallel with the rail.

Since the stopper 4 has a structure in which the lower edge and at least one side edge are formed in an arc shape, FIG.
Alternatively, as shown in FIG. 13, the lower half may be formed to have a large diameter and have a bilaterally symmetrical tear drop shape or a fan shape. At this time, the mounting direction of the stopper 4 is not limited.

The stopper 4 is arranged near the closing side end of the sliding door main body 1 and is provided between the closing side end of the rail 2 and the closing side vertical frame of the opening when the sliding door main body 1 is closed. A gap or a recess 6 is provided so that 4 is in a vertical state.

FIGS. 4 and 5 show another embodiment, in which an auxiliary rail 2a is provided in parallel with the rail 2 and is formed of an elastic material such as rubber on the upper surface of the auxiliary rail 2a. Alternatively, a stopper 4 provided with elasticity by incorporating a spring or the like is hung so as to contact in an inclined shape.

The hanging position of the stopper 4 in contact with the auxiliary rail 2a may be any position as long as it is within the traveling range of the sliding door body 1, and the stopper 4 is in a vertical state when the sliding door body 1 is closed. The gap or the formation of the recess 6 is also determined by the position of the stopper 4, and is provided independently of the wheels that run the sliding door body 1.

A support 3 having a stopper 4 pivotally mounted on a pivot 5 is attached to the sliding door main body 1 so as to be movable up and down. The holding operation unit 7 is attached to the sliding door body 1.

In the illustrated embodiment, the rail 2 is mounted above the opening to form the hanging door system in which the sliding door body 1 is suspended, but the invention is not limited to the hanging door.
Further, although the automatic closing mechanism of the sliding door body 1 is obtained by arranging the rails 2 in an inclined shape, it is not always necessary to adopt this method.

Further, although both the rail 2 and the auxiliary rail 2a are arranged above the opening, the rail 2 is arranged below the opening and the auxiliary rail 2a is arranged above the opening. May be

[0026]

As described above, according to the present invention, the elastic stopper having the lower edge and at least one side edge formed in an arc shape is arranged with the arc shape of the side edge in the opening side direction of the sliding door main body.
And, since it is pivotally attached so as to be swingable in the direction along the rail and is suspended, and is in contact with the upper surface of the rail or an auxiliary rail provided in parallel with the rail in an inclined manner,
When the sliding door main body travels, the stopper is inclined in a direction opposite to the direction in which the sliding door main body travels, and there is no obstacle to traveling.

The stopper 4 may have a bilaterally symmetrical teardrop shape or a fan shape. At this time, since the attaching direction of the stopper 4 is not limited, the construction work can be easily performed. .

To open the sliding door body, simply release the force in the opening direction with respect to the sliding door body. At this time, the stopper is inclined in the same direction as the sliding door body travels. The friction with the rail, the rail, or the auxiliary rail causes the sliding door body to automatically stop traveling in the closing direction.

Moreover, since the rail or the auxiliary rail is brought into contact with the upper surface of the rail, the weight of the sliding door body causes friction with the rail or the auxiliary rail.
Alternatively, no complicated stopper pressing structure using a spring on the auxiliary rail is required.

At this time, in order to run the sliding door body from the open state and the closed state, the sliding door body may be run against the elasticity of the stopper, and no special releasing mechanism or releasing operation is required. .

Further, when the rail or the auxiliary rail is provided with a gap in which the stopper is in a vertical state when the sliding door body is closed, or in the case of a recess, when the sliding door body is closed, the stopper is a gap due to its own weight, Alternatively, it does not need to rotate about the shaft attachment portion against the elasticity of the stopper when starting to run in the opening direction of the sliding door body, and the opening operation of the sliding door body can be smoothly performed without resistance. Of.

Further, the stopper can be moved up and down with respect to the main body of the sliding door, and by attaching an operation portion for vertically operating and holding the position, the stopper can be brought into and out of contact with the rail or the auxiliary rail. According to it, you can select the stop function in the open state of the sliding door body, and in the detached state the function of the stopper is released,
The sliding door body does not stop in the open state, and the automatic closing function is used.
