PROBLEM TO BE SOLVED: To provide an anti-swing structure for a top-railed sliding door, which positively constrains both lower ends of the sliding door in a traveling direction even when the top-railed sliding door is closed, and can efficiently prevent swinging and looseness of the sliding door in a width direction. SOLUTION: The anti-swing structure is arranged at a butt portion between a butt end face of the top-railed sliding door and a rebate vertically carved in a longitudinal frame. The anti-swing structure is constituted of a projecting portion, a lever, and an anti-swing member. The projecting portion moves to and fro by butting on the butt end face of the top-railed sliding door or separation from the same, and by a function of a compression spring. The lever is rockably supported by a pivotal shaft. The anti-swing member is slidably supported by a support member in an axial direction. The anti-swing structure is formed by rotatably pin-connecting the projecting portion and the anti-swing member to both ends of the lever.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing-prevention structure for an upper-hanging sliding door, which prevents run-out and rattling in the thickness direction of the upper-hanging sliding door.

[0002]

2. Description of the Related Art An upper hanging sliding door requires almost no sweeping area of a door plate such as a hinged door, does not generate a dead space, and has a flat floor surface without the need to provide a sill or rail on the floor. Its advantages are being re-recognized from the point that it is possible to provide a barrier-free living environment, such as being able to use a wheelchair.

[0003] However, as shown in FIG.
The lower end is free because it is suspended via a connecting rod on a runner 2 that supports a rotatable wheel on a rail 4 fixed to the Kamoi 3 and the swinging in the thickness direction of the sliding door is free. It is easy to cause rattling. As shown in FIG. 3, a guide groove 7 extending in the sliding door traveling direction is provided at the lower end of the upper hanging sliding door 1 in order to prevent such swinging of the upper hanging sliding door, and a lower guide 6 slidingly contacting the guide groove 7 is provided. Is provided.

[0004]

However, in the case where the swing of the upper hanging sliding door 1 in the thickness direction is prevented by the lower guide 6, if the upper hanging sliding door 1 is closed, only one end in the sliding door traveling direction is provided. Although the lower guide 6 prevents the swing in the sliding door thickness direction, the other end that abuts on the vertical frame 5 is free and swings in the sliding door thickness direction.

As means for solving such a problem, Japanese Patent Application Laid-Open No. 9-268834 proposes that a projection to be fitted into a guide groove at the lower end of an upper hanging sliding door is provided in a concave groove of a vertical frame. However, in the case of this prior art, from the viewpoint that the projection does not become a bottleneck for the safety of traffic and from the viewpoint of designability, the projection length must be within the depth of the groove formed in the vertical frame. The tip of the projection is tapered from the necessity of fitting the projection into the guide groove at the lower end of the upper hanging sliding door that swings in the thickness direction of the sliding door. It is difficult to secure a projection fitting depth sufficient to sufficiently prevent the protrusion. To solve this, the depth of the groove must be increased by using an extremely thick vertical frame, but there is a problem that construction costs are increased.

The present invention solves the above-mentioned problems in the prior art, and reliably restrains the lower portions at both ends in the running direction of the sliding door even in a state in which the upper hanging sliding door is closed, and effectively prevents deflection and rattling in the thickness direction of the sliding door. It is an object of the present invention to provide a swing prevention structure in an upper hanging sliding door.

[0007]

SUMMARY OF THE INVENTION The present invention for solving the above-mentioned problems is directed to an abutting portion between an opening of a hanging door and a door door which is engraved on a vertical frame so as to extend vertically. A projecting portion which moves forward and backward by the action of a compression spring, and a contact / separation of the wooden surface of the upper hanging sliding door; a lever pivotally supported by a pivot; and a support member slidably supported in the axial direction. The gist of the present invention is to provide a vibration preventing device comprising a vibration-preventing member, wherein the projection and the vibration-preventing member are rotatably pin-connected to both ends of the lever.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described based on preferred embodiments.

[0009]

According to the present invention, since the present invention has the above-described configuration, even when the upper hanging sliding door is in the closed state, the lower portions at both ends in the sliding door traveling direction are securely restrained to effectively prevent swinging and rattling in the sliding door thickness direction. can do.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on one embodiment. FIG. 1 is a perspective view showing a run-out preventing structure in an upper hanging sliding door of the present invention. FIG. 2 is a front view showing a main part of the shake prevention device.

1 and 2, reference numeral 11 denotes an upper hanging sliding door, 15 denotes a vertical frame, 16 denotes a door slot, and 17 denotes a guide groove, which extends at the lower end of the upper hanging sliding door 11 in the sliding door traveling direction. It is carved so that it does. The guide 6 shown in FIG. 3 is slidably fitted in the guide groove 17, and
The lower end of the other end of the upper hanging door 11 is restrained so as not to swing in the thickness direction of the sliding door when the door 1 is opened or closed or when the sliding door is closed.
Numeral 18 is the opening of the sliding door.

Numeral 19 denotes a steadying member, and when the opening 18 of the hanging door 11 comes into contact with the projection 20 of the steadying device and pushes it in, the lever 21 swings out and projects into the guide groove 17. Insert. The steady member 19 is supported by the support member 26 and is displaceable only in the axial direction. The cross-sectional shape of the steadying member 19 may be circular or square, but if it is circular, it is supported by a bearing (support member 26) having a hollow circular cross section.

The tip of the steadying member 19 which fits into the guide groove 17 has a tapered or semi-circular cross section so that the hanging door 11 can be securely fitted even if it swings in the thickness direction of the sliding door. Alternatively, the shape is preferably elliptical.

The anti-sway member 19 is provided with a pin 25, which is fitted into an elongated hole 24 formed at one end of the lever 21, and which is pivoted about the pivot 23 by the lever 21. The steady member 19 is displaced in the left-right direction as viewed in FIG.

The other end of the lever 21 is rotatably fitted to a pin 22 provided on the projection 20 via a long hole 24 ', and the projection 20 has a horizontal direction as viewed in FIG. , The lever 21 swings about the pivot 23 as the center of rotation.

The cross-sectional shape of the projection 20 may be square or circular, but in this embodiment, it has a circular cross-section. The protruding portion 20 is also supported by a supporting member (bearing or the like) 28 and can be displaced only in the axial direction. A compression spring 27 is in contact with the other end of the projection 20, and when the upper hanging sliding door 11 travels and the cut edge 18 pushes the projection 20 in the axial direction, the compression spring 27 contracts and simultaneously the projection 20 Pin 2 of
2 and the long hole 24 'of the lever 21 are fitted and connected to each other.
1 is swung counterclockwise as viewed in FIG.
The anti-sway member 19 is displaced to the right as viewed in FIG. 2 through the mating connection between the elongated hole 24 and the pin 25 at the other end, whereby the anti-sway member 19 is inserted into the guide groove 17 at the lower end of the upper suspension sliding door 11. It fits in and suppresses runout in the sliding door thickness direction.

When the leading edge sliding door 11 is moved from the closed state to move the wooden edge 18 away from the door frame 16 of the vertical frame 15, the compression spring 27 is actuated to move the projection 20 rightward as viewed in FIG. And return to the original position. As a result, the lever 21 swings clockwise as shown in FIG. 2 about the pivot 23 as the center of rotation, and retreats the anti-sway member 19 to the left.

If a plurality of holes are formed in the center of the lever 21 in the longitudinal direction to fit the pivot 23, the pivot 23 and the pin 2
2 and the distance between the pin 25 and thereby the stroke of the protrusion 20 and the
Stroke ratio can be changed. Thereby, for example, the stroke of the steady rest member 19 per displacement amount of the projection 20 is increased, and the guide groove 17 of the upper hanging sliding door 11 is increased.
It is possible to increase the amount of fitting of the steady rest member 19 into the slidable member.

By increasing the stroke of the anti-sway member 19 to increase the amount of fitting into the guide groove 17 and retreating the anti-sway member 19, the anti-sway member is moved inward from the surface of the vertical frame 15. 19 can be positioned, and when the hanging door 11 is opened, the traffic of residents and the like can be made safe and the appearance can be made good. On the other hand, when the steadying member 19 projects, the tip of the steadying member 19 can be fitted into the guide groove 17 far beyond the surface of the vertical frame 15.

[0020]

Since the present invention is constructed and operated as described above, even when the upper hanging sliding door is in the closed state, the lower portions at both ends in the running direction of the sliding door are securely restrained, and the thickness of the sliding door in the thickness direction is reduced. It is possible to prevent runout and rattling.
In addition, the stroke of the steady rest member is set as an amount that is a fitting depth to the guide groove enough to reliably prevent the swing in the thickness direction of the upper hanging sliding door.When the steady rest member is retracted, the stroke is smaller than the vertical frame surface. Because it can be positioned inside, it is possible to ensure the safety of traffic when the upper hanging sliding door is opened and to make the appearance good.
