BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retaining device for an inner slide rail in a hanging door provided at a doorway or a passage of a building.

[0002]

BACKGROUND OF THE INVENTION Generally,
In this kind of hanging door, a plurality of retainers are supported by retainers between the inward guide grooves above and below the outer slide rail and the outward guide grooves above and below the inner slide rail on which the door body is supported. There is one in which the ball is suspended by using a slide-type suspension rail in which the ball is rotatably interposed so that the door can be opened and closed more smoothly than the suspension roller type.

When using such a slide-type suspension rail, it is necessary to connect the inner slide rail and the door body. Regarding such a connection technique, heretofore, in Japanese Utility Model Publication No.
There are known ones disclosed in Japanese Patent Publication No. 1-453 and Japanese Utility Model Publication No. 5-19489. The former one integrally connects an inner slide rail and a door body side hanging metal fitting provided integrally on the door body side. However, in this case, when a load acts in the direction of swinging the door body in the front-rear direction, this load is concentrated on the groove fitting part between the ball and the outward guide groove part above and below the inner slide rail. Become,
There is concern that the inner slide rail may easily fall off, so it cannot be used as it is. On the other hand, in the latter, the locking hook integrally provided on the inner slide rail side and the inverted U-shaped door side hanging metal fitting integrally provided on the door side are locked using the locking pin. By doing so, the door body is configured to be swingable in the front-rear direction with the locking pin as the axis, and thereby the load in the front-rear direction acting on the door body is reduced. The locking pin of the door body is used as an axis to swing back and forth to release the door. However, even with this product, when the door swings back and forth, sliding resistance occurs between the door-side hanging metal fitting, the locking pin, and the locking hook, which acts as a load in the direction to remove the inner slide rail. However, the reality is that it is still unable to exert a sufficient retaining function.

The tip piece 13c of 3b is set so as to fit into the retaining groove 9f of the frame member 9. here,
The tip piece 13c of the retaining piece 13 is formed in a corrugated plate shape that protrudes in the front-rear direction in a state where the tip piece 13c is loosely fitted in the retaining groove 9f.
It is set so that as the strength of c increases, the swing width in the detachment preventing groove 9f becomes smaller. Here, the tip piece 1
Instead of forming the corrugated plate 3c, the tip piece 13c may be provided with a member such as a protrusion or a rubber damper that faces the front-rear direction. Even in this case, the thickness of the tip piece 13c in the front-rear direction is increased. The thickness can be reduced to reduce the swing width. Reference numeral 14 is a self-closing device, 15 is a piston cylinder for shock absorbing when closed, and 16 and 17 are holding devices provided for shock absorbing when opening and starting and stopping the closing operation.

In the embodiment of the present invention constructed as described above, the door body 1 is suspended on a slide type suspension rail 2,
Front and rear guide surfaces 9d and 9e whose upper part is formed on the frame member 9
The opening / closing operation is performed in a state of being guided by the door body 1. In this case, in the door body 1, the tip portion of the tip piece 13c of the retaining piece 13 fixed to the top surface of the door body Groove 9
The opening / closing operation is performed in a state in which it is loosely fitted to f. Therefore, when the door body 1 is subjected to a load in the front-rear direction and is rocked back and forth, the tip piece 13c of the door body 1 comes into contact with the groove side pieces on the front and rear sides of the removal preventing groove 9f. Thus, the swing width of the door 1 in the front-rear direction can be regulated. Moreover, in the present embodiment, since the tip piece 13c is formed in a corrugated plate shape and protrudes in the front-rear direction, the tip piece 1c
It is possible to further reduce the swing width in the retaining groove 9f of 3c.

As described above, the door body 1 includes the retaining piece 1
When 3 is fitted in the retaining groove 9f, the swinging in the front-back direction is restricted, whereby the swinging of the door 1 forwards and backwards causes the door-side hanging metal fitting 11 to the locking pin 12,
The load applied to the inner slide rail 5 via the hook portion 10c and the rail-side hanging metal fitting 10 can be reduced. As a result,
Outer guide grooves 5 above and below the inner slide rail 5
Since the load is not concentrated on the groove fitting portion between the balls 5 and 6 and the inner slide rail 5 is prevented from falling off, the reliability can be improved.

Of course, the present invention is not limited to the above-mentioned first embodiment, and the retaining piece is fitted into a retaining groove formed in the frame member to form a door body. It suffices if the front-rear direction runout can be regulated, and the slip-off preventing projection 18 is not directly provided on the door body 1 as in the second embodiment shown in FIG. 5, but is attached via a mounting bracket 18a. Although various configurations are conceivable, such as the third embodiment shown in FIG. 6 in which the door-side hanging metal fitting 11 is provided with a retaining piece 19 for retaining, the second embodiment has a retaining stopper. A damper 18c is provided on the tip end piece of the piece 18 to cushion the deviation preventing groove 9f and to further reduce the swing width of the deviation preventing projection 18 in the deviation preventing groove 9f. The swing width of the door can be reduced. Further, as shown in a fourth example in FIG. 7 , the rail-side hanging metal fitting is directly attached to the door body. Even with such a door body hanging structure, the rail-side hanging metal fitting is detached. The stopper protrusions 22 and 23 effectively prevent the inner slide rail 5 from coming off.

[0014]

In summary, since the present invention is constructed as described above, the slip-out preventing projection provided on the door body or the door-side hanging metal fitting is fitted in the slip-out preventing groove formed in the frame member. In this way, the swinging width of the door in the front-rear direction can be made small, and as a result, the back-and-forth swinging of the door can be suppressed to a slight amount, which reduces the swing load acting on the inner slide rail. This means that the inner slide rails can be effectively prevented from coming off, and the sliding doors can be opened and closed smoothly, but the rails will not come off and the door will be highly reliable.
