[0001]

BACKGROUND OF THE INVENTION The present invention relates to an upper runner attaching / detaching mechanism for a sliding door used in a house or the like, and more particularly, a sliding door which is moved by a traveling wheel in a runner passage formed in a rail above the sliding door as the sliding door is opened and closed. The present invention relates to a device for detaching an upper runner from a suspension door upper rail.

[0002]

2. Description of the Related Art An upper runner of a sliding door used in a house or the like is composed of a runner main body formed in a substantially box shape and a runner main body formed to move horizontally in a runner passage formed in an upper rail of the hanging door. It is composed of a traveling wheel that is supported and a suspension shaft that extends downward from the runner body to fix the suspension door.

In order to open and close the suspension door, the suspension door is fixed to a suspension shaft suspended from the runner body of the upper runner, and the upper runner passes through a runner passage formed on the upper rail as the suspension door opens and closes. It is configured to move in the opening and closing direction. . A passage notch having an opening in the downward direction is formed at an end of the hanging door upper rail on the wall side, and a resin stopper is fastened and fixed to the passage notch. The wall-side end surface of the runner body of the runner is brought into contact with the runner to restrict excessive movement of the hanging door in the opening and closing direction.

[0004] When it is necessary to replace the upper runner, first, the stopper made of a resin material which is fastened and fixed to the cutout portion of the passage is released and the stopper is removed, and the cutout portion of the upper runner is removed. Free space for
Then, the fixing of the suspension shaft of the upper runner and the suspension sliding door is released, and the runner body is moved to this empty space position. Then, after the upper runner is taken out from the empty space, a new upper runner is put in, the hanging door is fixed, and the stopper is tightened and fixed again.

Therefore, in order to attach and detach the upper runner, it is inevitable that the entire length of the passage cutout portion must be longer than the entire length of the runner main body. Considering this, the total length of the passage cutout had to be very long.

[0006]

However, when the entire length of the passage notch is increased in this way, it is necessary to increase the size of the stopper that is fastened and fixed to the passage notch. As a result, since the upper runner cannot be moved to the vicinity of the wall by the stopper, the upper runner cannot be fixed to the end of the hanging door for the hanging door to be moved to the wall.

[0007] Therefore, not only is it difficult to stabilize the hanging door itself, but also it is difficult to support the upper runner on the structural material in the vertical direction of the hanging door. Therefore, the upper runner attaching / detaching mechanism of the present invention improves the shape of the upper end portion of the runner body so that the upper runner can be attached to and detached from the passage notch even if the entire length of the passage notch is shortened. While shortening the total length of the notch and the size of the stopper,
This stabilizes the suspension door during use and facilitates the support of the suspension door on the upper runner.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, an upper runner attaching / detaching mechanism of a sliding door according to the present invention is provided in a horizontal direction by running wheels which horizontally support a runner passage formed in a hanging door upper rail. An upper runner attaching / detaching mechanism for detaching an upper runner of a hanging door movable in a direction from a notch formed in a lower end of a wall of an upper rail of the hanging door and having a downward opening. Is formed from a runner body, a traveling wheel pivotally supported by the runner body, and a suspension shaft suspended downward from the runner body to fix the suspension door, and at both upper ends in the movement direction of the runner body, A substantially arc-shaped curved surface portion close to the radius of the traveling wheel attached to the runner body is formed, and the curved surface portion formed at the upper end on the wall side of the runner body follows the vertical wall surface located at the end of the upper sliding door rail. Up Tilt the horizontal axis of the runner, characterized by being formed as a top runner can be desorbed from the passage notch while changing the inclination angle of the horizontal axis.

[0009]

When replacing the upper runner, first, the stopper fixed to the wall-side passage notch of the suspension door upper rail is removed to make the passage notch an empty space, and the upper runner is moved to this empty space position. At this time, the fixing with the hanging door is released as in the conventional case.

Then, the horizontal axis of the upper runner is tilted so that the substantially arc-shaped curved surface formed at the upper end of the upper runner on the wall side of the runner main body follows the vertical wall surface located at the end of the upper sliding door upper rail. The upper runner is removed from the empty space while gradually changing the inclination angle of the horizontal axis. It should be noted that if the suspension shaft is suspended from the runner body and tilted, it can be more easily removed.

In the present invention, since the upper end of the runner main body on the wall side is formed in a substantially arc-shaped curved surface portion close to the radius of the traveling wheel, the inclination of the horizontal axis of the upper runner can be reduced while being attached to the wall. It is possible to tilt the upper runner while changing it. After taking out the upper runner in this way, a new upper runner may be mounted again in the reverse procedure.

Since such detachment is possible, the upper runner can be detached from an empty space (passage notch) having a shorter overall length than the overall length of the runner body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the upper runner attaching / detaching mechanism of the present invention will be described with reference to the drawings. FIG. 1 is a partial cross-sectional side view showing a use state of the upper runner, and FIG.
FIG. 3 is a vertical partial cross-sectional view of the upper runner, and FIG. 3 is a partial cross-sectional side view showing an operating state of the upper runner during attachment and detachment.

The upper runner 10 includes a runner body 11 and
The running wheels 12 and 12 supported on the runner body 11
And a suspension shaft 13 that extends downward from the runner body 11 to fix the suspension door 1. Here, the runner main body 11 is formed in a band plate shape, and has a pair of running wheels 12, 12 on both sides thereof in the front-rear direction. The runner main body 11 has substantially arc-shaped curved surface portions 15 near the radius of the traveling wheels 12 mounted on the runner main body 11 at both upper end portions 14 in the moving direction of the runner main body 11. is there. The following description will be made with the wall surface 40 side of the runner body 11 as the wall side end surface 16 and the opposite wall surface 40 side as the opposite wall side end surface 18.

A fixing mechanism 19 (not shown in detail) is fixed to the suspension shaft 13, and the suspension door 1 is fixed via the fixing mechanism 19. On the other hand, the upper rail 20 for running such a runner main body 11 is formed in a dovetail shape with a cross-sectional shape opening downward. Specifically, the ceiling plate 2
2 and vertical plates 25, 2 suspended from both sides of the ceiling plate.
5 and horizontal rail plates 21 and 21 projecting from the lower ends of the vertical plates 25 and 25 so as to face each other. At the wall-side end of the upper rail 20, both vertical plates 25, 25 and horizontal rail plates 21, 21 are cut out with a shorter width than the runner body 11 to form a passage cutout 23. I have.

In addition, a resin stopper 30 also serving as an impact buffer is detachably fixed to the passage notch 23. Since the stopper 30 is fixed to the passage notch 23 such that one side thereof is in contact with the wall surface 40, the wall-side end surface 16 of the runner body 11 of the upper runner 10 abuts on the opposite wall surface 40 side of the stopper 30. Thus, the movement of the upper runner 10 is stopped, and the opening and closing movement of the hanging door 1 is stopped.

The notch 23 and the stopper 30
In the above embodiment, the total length of the upper runner is formed to be 52 when the total length of the passage notch 23 is 40. Next, attachment / detachment / replacement of the upper runner 10 in the above embodiment will be described. When it is necessary to attach / detach / replace the upper runner 10, first, the upper rail 20
The stopper 30 fixed to the passage notch 23 at the wall side end of the upper rail 20 is removed, and an empty space having a downward opening at the end of the upper rail 20 appears.

Next, a suspension shaft 13 of the upper runner 10;
After releasing the fixing between the fixing mechanism 19 and the suspension door 1 (not shown in detail), the upper runner 10 is moved to the empty space position formed in the passage notch 23 at the end of the upper rail 20, and the wall side of the runner main body 11 is moved. The end surface 16 is brought into contact with the wall surface 40. Then, as shown in FIG. 3, the horizontal axis of the upper runner 10 is tilted so that the substantially arc-shaped curved surface portion 15 formed on the wall-side upper end portion 14 of the runner body 11 of the upper runner 10 follows the wall surface 40. The upper runner 10 is detached from an empty space while changing the inclination angle of the horizontal axis.

At this time, the wall-side upper end 14 of the runner main body 11 has a substantially arc-shaped curved surface portion 15 close to the radius of the traveling wheel 12.
First, the curved surface portion 15 on the side of the wall-side end surface 16 abuts on the wall surface 40 with which the wall-side end surface 16 of the runner body 11 abuts with the inclination of the runner body 11. Then, the inclination of the runner body 11 is gradually increased so that the curved surface portion 15 follows the wall surface 40, and the inclination of the horizontal axis of the upper runner 10 is changed.

On the other hand, as the upper runner 10 inclines, the opposite side of the upper runner 10 is lifted, and the runner body 1 is lifted.
The running wheel 12 protruding from the opposite side of the upper end face 17 of the first runner abuts on the upper surface of the upper rail 20 which is the ceiling surface 22 of the runner passage 24, and is formed on the opposite side end face 18 of the runner body 11. The curved surface portion 15 abuts on the ceiling surface 22 to change the inclination of the horizontal axis of the upper runner 10 and incline the upper runner 10 in a rotating manner.

If the suspension shaft 13 hanging from the runner body 11 is tilted, it can be more easily attached and detached. Since the attachment / detachment becomes possible, when the total length of the passage notch 23 is 40, the runner body 1
It was confirmed that even if the total length of 1 was 52, the replacement of the upper runner 10 did not cause any inconvenience.

After the old upper runner 10 is taken out, the new upper runner 10 is mounted again in the reverse order, and the suspension door 1 is fixed to the suspension shaft 13 of the upper runner 10 via the fixing mechanism 19, and the passage is removed. When the stopper 30 is fixed again to the notch 23, the replacement of the upper runner 10 is completed. In the present embodiment described above, the runner body 1 of the upper runner 10
Assuming that the total length of 1 is 52, the total length of the passage cutout 23 is 40, but this ratio can be changed as appropriate according to the implementation. In this case, if the entire length of the passage cutout portion 23 is close to the entire length of the runner body 11, when the upper runner 10 is detached, the wall side end surface 1 of the runner body 11
The upper runner 10 can be taken out in an inclined state with some margin without contacting the upper runner 6 with the wall surface 40.

In this embodiment, the arcuate curved surfaces 15, 15 are formed at both upper end portions 14, 14 of the runner main body 11. However, depending on the type of the hanging door 1, one upper end of the runner main body 11 may be provided. The curved surface portion 15 may be formed only in the portion 14. In addition, the arc of the curved surface portion 15 can be appropriately selected within a range close to the radius of the traveling wheel 12 axially attached to the runner main body 11, and the entire shape of the runner main body 11 not described in the above embodiment is also appropriately selected. Can decide.

[0024]

As described above, according to the upper runner attaching / detaching mechanism of the suspension door of the present invention, by improving the shape of the upper end portion of the runner body, the passage notch can be cut even if the entire length of the passage notch is kept short. The upper runner can be attached to and detached from the upper part, the length of the passage cutout part and the size of the stopper can be shortened, and the suspension door can be stabilized during use and the suspension door can be easily supported by the upper runner. .
