Description

[Detailed description of the invention] This invention is designed to automatically fix and hold the lower end of a door suspended from a ceiling rail and run laterally to prevent the door from opening and swinging. This relates to a device that has been used.

In the existing device of the same kind, when the sliding rod protruding from the side of the door collides with a wall surface etc. and sinks into the door, the floor member provided at the lower end of the door, which is linked to the sliding rod via a link mechanism, descends. Then, it came into pressure contact with the floor.

However, in such conventional devices, the moving distance between the sliding rod and the floor-contacting member is constant, so if the floor surface is uneven, the sliding rod will not completely sink into the door, and as a result, the wall surface There is a drawback that a gap is created between the door and the floor contact member, or even if the sliding rod is completely submerged within the door, the floor contact member does not come into close contact with the floor surface.

The present invention has been made to solve the above-mentioned drawbacks, and will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, a door 1 is suspended from a ceiling rail 2 so that it can move laterally with rollers 3.

At the lower end of the door 1, near both left and right ends of the upper horizontal piece 4a of the lower frame rod 4, which has a U-shaped side surface, there are window holes 5 that are elongated in the left and right direction (the right window hole is not shown). ) is cut out.

On both sides of the right end of the window hole 5 on the upper surface of the horizontal piece 4a,
A pair of front and rear support plates 6, 6 are erected, facing laterally and parallel to each other with a slight interval, and a support shaft 7 is fixed between the upper ends of the surface support plates 6, 6. .

A flooring rod 8 having an approximately H-shaped side surface and having the same length as the frame rod 4 is loosely fitted into the frame rod 4, and pressure contact members 9, 9 made of an elastic material are attached to the lower end of the flooring rod 8. ing.

Near the left end of the horizontal piece 8a of the flooring rod 8 and the window hole 5 of the frame rod 4
A pair of front and rear suspension plates 10.10 are erected below the suspension plates 10, 10, which face laterally and are parallel to each other with an interval narrower than the interval between the support plates 6, 6.

11 is a connecting plate of the frame rod 4 and the ground rod 8, forming a front and rear pair;
Its lower end is pivotally attached to the lower part of the outer surface of the rain support plate 10゜10 with a support shaft 12, and elongated holes 13 and 1 are also bored at the upper end.
3 is engaged with the support shaft 7 of the support plate 6.

14 is a torsion spring having a bifurcated shape, the lower end of which is connected to the support shaft 1.
5 is fixed between the upper ends of the rain support plates 10 and 10, and the upper end is also fixed to the support shaft 7 of the support plate 6.

A device similar to that described above is also provided between near the right end of the frame rod 4 and near the right end of the flooring rod 8, facing in the same direction.

As shown in FIG. 3, the ground rod 8 is normally urged toward the upper left by the spring 14, protrudes from the left side of the door 1, and comes into contact with the lower surface of the horizontal piece 4a of the frame rod 4. are in contact with each other.

As shown in FIG. 4, when the door 1 configured as described above travels to the left and collides with the wall 16, the protruding end of the grounding rod 8 is pushed into the frame rod 4 against the spring 14. It will be done.

The support shaft 15 fixed to the lower end of the spring 14
When moving to the right from the bent portion 14a of 4, the floor contact rod 8 is biased toward the lower left, and descends to the floor surface 17.
The lower end of the door 1 is fixed.

When the door 1 in this state is moved to the right, due to the frictional force between the pressure welding material 9 and the floor surface 17, the floor rod 8 does not slide on the floor surface 17, and only the frame rod 4 moves toward the door 1. At the same time, the bent portion 14 of the spring 14 moves to the right against the spring 14.
a moves to the right from the support shaft 15.

In this way, the ground contact rod 8 is biased upwardly and to the left by the spring 14, resulting in the state shown in FIG. 3.

The linking plate 11 is for guiding the floor contacting rod 8 to smooth its movement, and also for preventing the spring 14 from being damaged.

As is clear from the above description, when the door 1 is closed, the floor rod 8 can move up and down within the range allowed by the elongated hole 13, even after contacting the floor surface 17, while being biased downwardly to the left by the spring 14. Therefore, even if the floor surface 17 is uneven, pressure contact can be made in accordance with the irregularity, and the floor rod 8 cannot completely sink into the door 1, resulting in a gap between it and the wall body 16. Not at all.
