DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door stopper installed on a sliding door rail for stopping the sliding door near a vertical frame.

[0002]

2. Description of the Related Art Conventionally, if a sliding door is closed tightly and vigorously, the sliding door rebounds due to a recoil that collides with the vertical frame, and the sliding door cannot be closed properly near the vertical frame. For this reason, a stopper such as a leaf spring is attached to the sliding door rail, and the sliding door is pressed to decelerate and close around the vertical frame. However, since these sliding door stoppers do not have means for adjusting the pressing force against the sliding door, it is difficult to adjust the pressing force after the sliding door is attached to the sliding door rail, and the usability is poor. was there.

[0003]

Means for Solving the Problems To solve the above problems, the inventor of the present invention provides a leaf spring-like sliding door which is attached to the end of the sliding door rail 2 and presses and stops the sliding door 1 body. The stopper 3 has an elastic pressing portion 3a which presses the sliding door 1 and gently bends, and a mounting portion 3b which is bent in a substantially U-shaped cross section from the root of the pressing portion toward the end of the stopper 3. With the mounting part 3b
The invention has invented a stopper for a sliding door in which an adjustment screw hole 5h is formed in the front side plate v, and the adjustment screw hole 5 is inserted through the adjustment screw hole 5h.

[0004]

According to the present invention, a stopper 3 is provided at an end of a sliding door rail 2 to prevent the sliding door 1 from rebounding when the sliding door 1 is pressed to close the sliding door 1, so that a side surface of the sliding door 1 and a vertical frame are provided. 4y is to be properly closed without any gap.

Hereinafter, description will be made with reference to the drawings. In FIG. 1, reference numeral 3 denotes an embodiment of the stopper of the sliding door of the present invention,
It mainly comprises a gently curved pressing portion 3a, a mounting portion 3b having a U-shaped cross section, an adjusting screw 5, and the like. The stopper 3 is made of a metal such as iron, aluminum, stainless steel or the like, an alloy thereof, a synthetic resin such as vinyl chloride or the like, and a material usually used as a raw material of a leaf spring, and according to the colors of the sliding door, the sliding door frame and the sliding door rail 2. It is arbitrarily colored.

The pressing portion 3a is formed to be gently curved, so that not only the portion in contact with the sliding door 1 but also the entire curved pressing portion 3a has elasticity. Then, the topmost portion of the pressing portion 3a is pressed against the sliding door 1 main body, thereby pressing the sliding door 1 and bringing the sliding door 1 to a predetermined position near the vertical frame y.
Is to be stopped. Pressing part 3 in this case
The cross-sectional shape of “a” is a parabolic shape that is tilted to the left,
However, the present invention is not limited to this, and may be provided in a normal parabolic or semicircular shape.

The mounting portion 3b is provided for fixing the stopper 3 to the end of the sliding door rail 2. The mounting portion 3b is bent in a substantially U-shape in cross section. As shown in FIG. 3, an insertion plate u is inserted into the boundary between the groove of the gate and the sliding door rail 2, and the insertion plate u and the front side plate v are connected. The stopper 3 is attached and fixed while holding the sliding door rail 2.

In the embodiment, as shown in FIG.
Has a U-shaped cross section and is the same as the cross section of the sliding door rail 2, but the bent shape may be a U-shape with no corners, or may be appropriately changed according to the shape of the sliding door rail 2. Needless to say. Also, as shown in FIG. 7, the distance between the insertion plate u and the front side plate v is set so as to be tapered toward the end like a hairpin, and the elasticity is imparted to increase the clamping force on the sliding door rail 2. If it is strengthened, the stopper is securely fixed, and the stopper does not wobble at the time of mounting and after the mounting.

The adjusting screw 5 is inserted through an adjusting screw hole 5h formed in the front plate v of the mounting portion 3b.
Further, it is intended to adjust the pressing force of the stopper 3 against the sliding door 1 by changing the vertical height of the pressing portion 3a.

There are two methods for adjusting the pressing force.
The method is as follows. That is, as shown in FIG. 8, an adjustment screw hole 5 having the same diameter as the adjustment screw 5 is formed in the front side plate v.
h, a screw having a flat screw tip is used as the adjusting screw 5, which is inserted only into the front side plate v, and the adjusting screw 5 is brought into pressure contact with the sliding door rail 2. Screw and the front side plate v are fitted, and the adjusting screw 5
The front side plate v and the pressing portion 3a move up and down by the amount of the adjustment screw 5 in the range of the length.

As a second method, as shown in FIG. 9, an adjusting screw hole 5h slightly larger than the diameter of the adjusting screw 5 and smaller than the diameter of the screw head is formed in the front plate v, and a screw hole is further formed in the sliding door rail 2. 5x, the adjusting screw 5 is inserted into both the front plate v and the sliding door rail 2, and the screw head locks the front plate v, and the front plate v and the pressing portion are screwed in by the adjusting screw 5. There is a method of raising and lowering 3a. In the second method, since the adjusting screw 5 is inserted into the sliding door rail 2, the adjusting screw hole of the insertion plate u is inserted into the portion where the adjusting screw 5 is inserted (immediately below the adjusting screw hole 5 x formed in the sliding door rail 2). 5h must be drilled.

However, depending on which of the two methods is adopted, the shape of the mounting portion 3b must be changed. In the case of the first method, it is indispensable that the stopper is attached, the sliding door rail 2 is brought into close contact with the front side plate v as shown in FIG. . Even if the stopper 3 is attached to the sliding door rail 2 in a state where the adjusting screw 5 is not brought into contact with the sliding door rail 2, the screw portion of the adjusting screw 5 will float. This is because the pressing force cannot be adjusted.

On the other hand, in the second method, the surface side plate v is provided with a certain degree of elasticity, and the elasticity is regulated by a screw head.
Since the front side plate v and the pressing portion 3a are moved up and down by the degree of screwing of the adjusting screw 5, it is necessary to leave a certain gap between the front side plate v and the sliding door rail 2, contrary to the first method. become. Next, a method of mounting and adjusting the stopper 3 of the sliding door of the present invention will be described. First, before constructing the opening of the sliding door frames 4x, 4y, the stopper 3 is inserted into the end of the sliding door rail 2, the sliding door rail 2 is fitted into the groove of the Kamoi x, and the sliding door frame is constructed by a usual method. At this time, the position of the stopper is a neutral position between a position where the pressing force is maximized and a position where the pressing force is minimized.

Next, the sliding door 1 is attached to the sliding door frames 4x, 4y. At this time, if the position of the pressing portion 3a is set closer to the sliding door rail 2, the pressing force applied to the sliding door 1 is reduced, and the sliding door frames 4x, 4y are provided. The sliding door 1 can be easily attached to the vehicle.

Then, when the sliding door 1 is actually run,
If the sliding door 1 collides with the vertical frame 4y and rebounds, the adjusting screw 5 is used to adjust the pressing portion 3a closer to the sliding door 1 side, the pressing force on the sliding door 1 is increased, and before the vertical frame 4b rebounds. Adjust so that it stops near 4y.

On the other hand, if the pressing force of the stopper 3 is too strong and the sliding door 1 stops before the vertical frame 4y,
The pressing portion 3a is moved closer to the sliding door rail 2, the pressing force on the sliding door 1 is reduced, and the sliding door 1 is adjusted to stop before rebounding near the vertical frame 4y.

At this time, a screw for fixing the stopper 3 to the sliding door rail 2 is not used. However, if necessary, a fixing screw hole is provided in a mounting portion, or a horizontal hole is provided at an end opposite to the mounting portion of the stopper. An elliptical fixing screw hole for making a necessary escape when pressing the sliding door 1 is provided therein, and the fixing screw is inserted slightly loosely into the sliding door rail so that the sliding door can escape when pressed. Can also be fixed. Further, in the present embodiment, the stopper 3 is provided on the door, but it may be provided on the threshold, and may be provided on the side of the sliding door rail 2 instead of the bottom.

FIG. 10 shows a modification of the stopper of the present invention.
As described above, a horizontal portion may be provided at a position lower than the top of the pressing portion 3a, an adjusting screw hole 5h may be formed in the horizontal portion, and an adjusting screw hole 5x may be formed in the rail 2 to adjust the pressing force. is there. Further, as shown in FIG. 11, two pressing portions 3a are provided, and adjustment screw holes 5 are formed in recesses between the two pressing portions 3a.
h, a modified example in which an adjustment screw hole 5x is formed in the rail 2 and the adjustment screw 5 is inserted through the screw holes 5h and 5x is also conceivable. Then, a fixing screw hole 6h is formed in one end flat surface of the stopper 3, and the fixing screw 6 is inserted through the sliding door rail 2,
Adjust the pressing force.

[0019]

According to the above construction, the stopper 3 is used for the sliding door 1.
By pressing and holding, the sliding door 1 can be prevented from colliding with the sliding door frames 4x, 4y, and even if the sliding door 1 is tightly closed, it can be properly closed in the vicinity of the vertical frame 4y,
And since it can prevent that the sliding door 1 collides with a sliding door frame,
The sliding door 1 and the sliding door frame can be prevented from being damaged. Further, since the stopper 3 is provided with the adjusting screw 5, the pressing force of the stopper 3 against the sliding door 1 can be easily adjusted. Since the stopper 3 presses and holds the sliding door 1 at the time of closing, it is possible to prevent rattling of the sliding door 1 in a strong wind or the like and occurrence of rattling noise due to the rattling.
