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 stop device of this type, it is generally practiced to stop an end face of a sliding door by abutting it against a vertical frame of an opening at a closed position of 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 conventional system in which the end surface of the sliding door is brought into contact with the vertical frame of the opening and stopped, the sliding door may bounce at the time of closing and a gap may be formed in the closed end surface. In some cases, the middle sliding door may not have an abutting vertical frame. Further, in the above-mentioned conventional method of stopping the door roller by contacting it with the end surface of the groove of the guide rail, it is troublesome to make an adjustment to position the end surface of the sliding door at an accurate closed position when the door roller stops, and when the door roller stops However, there is also a problem that it is easy to get on the upper part of the groove end portion. In order to solve the above-mentioned problem, a stopper pin is planted on a guide rail extension that is continuous with the end portion of the guide rail, and a stop block that is fixed to the stopper pin is fixed to the lower end surface of the sliding door body. A device has been proposed.

[0004]

[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.

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.

[0006]

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).
Is mounted on the sliding door body (3) and the sliding door body (3) is opened and closed by rolling the door roller (1) along the guide rail (5) provided on the threshold (4). In a sliding door stopping device in which the stopper member (6) provided at the end of (5) stops the sliding door body (3), the stopper member (6) is a guide continuous to the end portion of the guide rail. The rail extension part (6B) is provided, and the abutting part (6C) continuously protruding from the sill (4) is integrally formed with the guide rail extension part (6B) to project. 2) includes a pocket (2A) that receives the abutting portion (6C) when the sliding door is closed, and a stop portion (2) facing the abutting portion (6C) on the inner wall of the pocket (2A).
B) is formed.

[0007]

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.

[0008]

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 axially supported by a door roller housing 2 having an inverted U-shaped cross section, and the door roller housing 2 is provided inside an inverted L-shaped notch 3A formed on the back side of the lower corner of the sliding end of the sliding door body 3. The flange portion 2C on the outer periphery of the back surface of the door roller housing 2 is attached and fixed to the back surface of the sliding door body 3 by the screw fixing means 9. Further, a guide rail 5 having a V-shaped groove 5A is provided so as to be embedded in the sill 4, and a stopper member 6 formed by integral molding of plastic is arranged at its end in a continuous manner. There is. This stopper member 6 is a V-shaped groove end portion 6 which is continuous with the groove 5A and constitutes the end wall surface of the groove 5A.
The guide rail extension 6B has an end face A, and the abutment portion 6C is formed integrally with the guide rail extension so as to continuously project from the guide rail extension 6B. The abutting portion 6C has a concave hole 6D on the upper surface. Further, in this stopper member 6, the guide rail extension 6B is provided with a first attaching tool 7-1 with a screw, and the recessed hole 6D portion of the abutting portion 6C is provided with a second attaching tool 7-2 with a screw. It is fixed to the threshold 4. Further, the door roller housing 2 is located at a lower corner thereof, and when the sliding door is closed, the contact portion 6 of the stopper member 6 is provided.
It has an inverted L-shaped notched pocket 2A that receives C and is integrally provided with it by integrally molding, and an abutting portion 6 is provided on the inner wall of the pocket 2A.
A stop portion 2B facing the C is formed, and a sheet-shaped shock absorbing member 8 is attached thereto.

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 vicinity of the guide rail extension 6B on the stopper member 6 side, The stop portion 2B of the door roller housing 2 collides with the abutting portion 6C of the stopper member 6 and the sliding door body 3 stops at the closed position. At the time of the collision, the stopper member 6
Is longer than the guide rail 5 in the collision direction, and the sill 4 is formed by the front and rear first and second attachments 7-1 and 7-2.
Since it is fixed to, the impact at the time of collision is effectively absorbed by the deformation of the concave hole 6D and the like.

[0010]

The present invention has been described in detail above, and the stopper member is provided with the guide rail extension portion which is continuous with the end portion of the guide rail, and has the abutting portion which continuously projects onto the sill. Since the structure is formed integrally with the guide rail extension, the stopper member can be attached to the sill with sufficient strength, and will not wobble, distort the protruding position, or bend even after long-term use. Structurally robust and safe. Further, the door roller housing integrally includes a pocket portion that receives the impact portion when the sliding door is closed, and a stop portion that faces the impact portion is formed on the inner wall of the pocket portion. Since it is integrated, the number of parts is small, and it can be attached in a single operation, and the work is efficient.
