[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a sliding door stopping device such as furniture, which is mounted on a guide rail terminal for guiding a door roller and stops the sliding door.

[0002]

2. Description of the Related Art As a conventional stopping device of this type, at the door closing position of a sliding door, the end face of the sliding door is abutted against a vertical frame of an opening to stop the sliding door. Further, it is also attempted to bring the door roller into contact with the end surface of the groove of the guide rail to stop it. However, in the method of stopping the end surface of the conventional sliding door by abutting against the vertical frame of the opening, the sliding door may bounce at the time of closing, resulting in a gap in the closed end surface. The sliding door may not have a vertical frame to abut. Further, in the method of stopping the conventional door roller by contacting the terminal end surface of the groove of the guide rail,
There is also a problem that it is troublesome to set up the end face of the sliding door at an accurate closed position when the door roller stops, and the door roller easily rides on the upper part of the groove end portion when the door roller stops. In order to solve the above problems, a stopper pin is planted on a guide rail extension that is continuous with the end portion of the guide rail,
There has been proposed a stopping device in which a stopper block and a stopper block, which is provided in contact with a stopper pin, are fixed to the lower end surface of a sliding door body.

[0003]

[Problems to be Solved by the Invention] However, in the above-mentioned proposed technique, there is a problem that the stopper pin wobbles and is structurally weak due to the impact of the sliding door due to long-term use. The stop block must be fixed and provided, and there is a problem that the work is troublesome and the number of parts increases.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and is a sliding door stop device that can always stop a sliding door at an accurate stop position and that is easy to install and adjust. An object of the present invention is to provide a sliding door stop device that is structurally robust and easy to install.

[0005]

Therefore, in the sliding door stop device of the present invention, as is apparent from the illustrated embodiment, the door roller housing (2) pivotally supporting the door roller (1).
The sliding door body (3) and the sliding door body (3) is opened and closed by rolling the door roller (1) in the groove (5A) of the guide rail (5) provided on the sill (4). At this time, with the stopper member (6) provided at the end of the guide rail (5),
In the sliding door stopping device adapted to stop the sliding door body (3), the stopper member (6) has a guide rail extension (6) continuous with the end portion of the guide rail (5).
B), and the guide rail extension (6B) has a groove (5
The abutting portion (6C) forming the terminal wall portion of (A) is integrally formed, and the door roller housing (2) projects into the groove (5A), and when the sliding door is closed, the abutting portion (6C) is formed. The stop portion (2B) that abuts against 6C) is formed so as to project from the lower end side surface portion (2A).

[0006]

Therefore, in such a structure, the stopper member (6) can be attached to the sill (4) and the sliding door body (3) at an accurate position with sufficient strength, and the sliding door body (3) can be attached. When closed, the stopper portion (2B) of the door roller housing collides with the abutting portion (6C) of the stopper member,
The sliding door body (3) stops in the correct closed position. Further, since the abutting portion (6C) of the stopper member is located in the guide rail extension portion (6B) in the groove (5A), it does not project upward, so when passing through a threshold,
There is no fear of hindering it.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the illustrated embodiments. The door roller 1 shown here is pivotally supported by a door roller housing 2 having an inverted U-shaped cross section, and the door roller housing 2 is mounted on the sliding end of a sliding door body 3 with its flange portion fixed by screw fixing means 8. ing. Further, a guide rail 5 having a groove 5A is provided so as to be embedded in the sill 4, and a stopper member 6 is arranged at the end of the guide rail 5 so as to be connected to the sill 4. It is attached at 7. This stopper member 6 constitutes a guide rail extension 6B having a groove end portion 6A continuous with the groove 5A and an end wall portion of the groove 5A integrally formed continuously with the guide rail extension. It is composed of a contact portion 6C. Also, the door roller housing 2 is
It is located on the lower end side face 2A and projects into the groove 5A,
When the sliding door is closed, the stop portion 2B that abuts the abutting portion 6C of the stopper member 6 is integrally formed to project. In addition,
In the above-described embodiment, since the stop portions 2B are formed on both side surfaces of the lower end of the door roller housing 2, either one of them may be used when attaching to the sliding door body 3, so that versatility as a door roller component can be sufficiently exhibited. The number of parts can be reduced.

With such a structure, when the door roller 1 rolls in the groove 5A to open and close the sliding door body 3, the door roller 1 reaches the guide rail extension 6B on the stopper member side, and the stopper member. Since the stop portion 2B of the door roller housing 2 collides against the collision portion 6C of 6, the impact force is not applied to the door roller 1 itself. Also, the abutting portion 6C of the stopper member
Since it is at the end of the guide rail extension B, it does not project upward, so there is no danger of it being obstructed when passing through a sill.

[0009]

The present invention has been described in detail above, and the stopper member has a guide rail extension continuous with the end portion of the guide rail, and the guide rail extension has a groove on the guide rail. Since the abutment part that constitutes the terminal wall part is integrally formed, the stopper member can be attached to the sill with sufficient strength, and its position does not change even if it is used for a long time. Structurally robust and safe. Further, the door roller housing is formed with a stop portion protruding into the groove and protruding against the lower end side surface so as to contact the contact portion when the sliding door is closed, and the door roller housing and the stop portion are integrated. Therefore, the number of parts is small, and the installation can be performed in a single operation, and the work is efficient. Further, since the abutting portion 6C of the stopper member is located in the guide rail extension 6B in the groove 5A, it does not project upward, so there is no danger of it being obstructed when passing through a sill. There is an effect.
