JP2001003631A - Mechanism for preventing swing of overhang door - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a swing prevention mechanism of a simple structure which stably holds the lower part of an overhang door to prevent its lateral swing, thus permitting smooth travel, and maintaining a closed attitude achieved by the door. SOLUTION: In an overhang door A hung on an upper fixed rail 2 via a traveling element 3 in such a way as to freely travel, a roller 5 resiliently pressed against a lower floor face by means of a spring at all times is mounted at the lower end of the door plate 1 of the overhang door in such a way as to be capable of rotational movement along the advancing direction of the overhang door, and at least the outer peripheral grounding face part of the roller 5 is formed from a material with great friction resistance, such as rubber.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing door swing preventing mechanism for preventing a swing of a lower portion of a swing door from right and left and compensating for stable running.

[0002]

2. Description of the Related Art In general, a hanging door is unstable because it has a free lower portion and lacks stability in the left-right direction (the thickness direction of the door). In particular, when the hanging door is in the closed position, the free lower portion of the door swings easily and is dangerous when carelessly leaning against the door plate surface.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention is to provide a swing which can hold a lower portion of a hanging door with good stability, prevent swinging in the left and right direction, and can maintain a smooth running and a stable closing posture by the door. The main purpose is to provide a prevention mechanism with a simple structure.

[0004]

In order to achieve the above object, the present invention takes the following technical measures. That is, in the swing door swing prevention mechanism according to the present invention, in the hanging door A which is hung freely on the upper fixed rail 2 via the running body 3, the floor surface is always lower by the elastic machine 4. B
A rotating roller 5 elastically pressed against the sliding door is attached to the lower end of the door plate 1 of the hanging door so as to be rotatable along the direction of travel of the hanging door. Of a material having a large frictional resistance.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS It is preferable that the outer peripheral ground contact surface of the rotary roller 5 is made as large as possible so that a large frictional resistance is generated with respect to a side slip perpendicular to the direction of rotation.
Further, it is preferable that the grounding surface portion is made of natural rubber, synthetic rubber, or an elastic resin material.

Although the number of the rotating rollers 5 attached to the lower surface of the door plate 1 is not limited, it can be used, for example, by attaching it to one end portion or both end portions of the door plate 1 or three places at both ends and an intermediate portion.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below based on an embodiment shown in the drawings. In FIGS. 1 to 3, reference numeral A denotes a hanging door according to the present invention, which is hung on a rail 2 fixed to an upper frame or the like of a fitting so as to be able to run in a linear direction via running bodies 3 and 3. I have. In the present invention, a rotating roller 5 constantly elastically pressed against a floor B below by a spring 4 such as a spring can be rotated on the lower surface of the door plate 1 of the hanging door along the traveling direction of the hanging door. Attached to.

[0008] The outer peripheral ground contact surface of the rotary roller 5 is set to be as large as possible so that a large frictional resistance is generated with respect to a side slip perpendicular to the rotational traveling direction. Further, the grounding surface portion 5a of the rotating roller 5 is formed of natural rubber, synthetic rubber, or an elastic resin material. In this embodiment, only the outer peripheral surface portion of the rotating roller 5 is formed of an elastic material, but the entire rotating roller 5 may be formed of a male material. Further, it is preferable to form a tread on the outer peripheral surface of the rotating roller as shown in the figure in order to accumulate the frictional resistance in the lateral direction.

In the above embodiment, the rotating roller 5 is pivotally supported on the case 6 by the pin 7 as a fulcrum.
The case 6 is embedded in the door plate 1 and fixed with fixing screws 9, and the rotary roller 5 is always elastically moved downward. Any configuration may be used as long as it has a pressing structure. For example, as shown in FIG. And the case 16 can be formed so as to be embedded and fixed in the door plate 1.

In the above embodiment, as shown in detail in FIG. 3, a rotating roller 5 is attached to one end of the lower surface of the door plate 1, and a guide pin 12 projects from the floor to the other end, and is formed on the lower surface of the door plate. 13, the rotary roller 5 is slidably engaged. Alternatively, as shown in FIG. 4, the rotating roller 5 may be attached to both ends of the lower surface of the door plate, or three places of both ends and an intermediate portion. Good.

With the above-described structure, the door plate 1
2 can be effectively prevented from sliding in the lateral direction perpendicular to the direction of travel of the door plate as shown by the imaginary line in FIG. In addition, when the door plate 1 advances in the linear direction, the rotating roller 5 also rotates with the movement of the door plate, so that the door plate 1 can run smoothly.

Although the embodiments which are considered to be representative of the present invention have been described above, the present invention is not necessarily limited to only the structures of the embodiments, but has the constitutional requirements of the present invention and the object of the present invention. Is achieved, and the present invention can be implemented with appropriate modifications within a range in which the following effects can be obtained.

[0013]

As described above in detail, according to the present invention, it is possible to effectively prevent the swinging of the hanging door in the left-right direction by a simple mechanism, to achieve smooth running, and to stably hold the closing posture by the door. There is an effect that can be done.
