Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door body suspension device for 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 in the front-back direction, this load is concentrated on the outer guide groove parts on the upper and lower sides of the inner slide rail and the groove fitting part of the ball. 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 lock pin of the door can be released by swinging back and forth around the axis. However, even if this is done, as a result of the fact that the axial diameter of the locking pin and the horizontal inner diameter of the locking hook and the hanging metal fitting are the same, when this causes the door body to swing back and forth, The locking pin, the locking hook, and the door-side hanging metal fitting are twisted to generate a large sliding resistance, which acts as a load in the direction to remove the inner slide rail, and still exerts a sufficient retaining function. The reality is that you cannot do it.

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a door body that constitutes a self-closing hanging door provided at a doorway or a passage of a building.
Is stored in a door pocket 3 provided inside a room on one side of the opening from a closed position where the opening is closed in a state of being hung on a slide type suspension rail 2 provided below the opening. It is provided so that it can be moved left and right until the storage position where the opening is opened.

Here, the slide type suspension rail 2 is integrally mounted on the side of the body, and the outer slide rail 4 in which upward and downward inward guide groove portions 4a and 4b are formed and the door body 1 are supported, An inner slide rail 5 in which upward and downward outward guide groove portions 5a, 5b are formed, and a plurality of balls 6 rotatably interposed between the respective facing guide groove portions 4a, 5a and 4b, 5b, A retainer 7 that supports the balls 6 in a line at a predetermined interval. Then, the movement of the retainer 7 with respect to the outer slide rail 4 and the movement of the inner slide rail 5 with respect to the retainer 7 are simultaneously performed by the rolling of the balls 6, whereby the movement of the inner slide rail 5 with respect to the outer slide rail 4 is performed. Is configured.

A rail receiving member 8 is fixed to the outer slide rail 4 with a screw 4c via a reinforcing member 4d, and the rail receiving member 8 is attached to a frame member 9 integrally provided on the upper body. Although the suspension rail 2 is fixed to the body side by fixing, the mounting piece 8a protruding from the upper edge portion of the rail receiving member 8 is provided with a long hole 8b which is long in the vertical direction. The frame member 9 includes a frame receiving member 8
A supporting piece 9a for supporting the lower surface of the rail is bent, and the rail receiving member 8 is vertically positioned with respect to the frame member 9 by adjusting the screw 9c in and out of a screw hole 9b formed in the supporting piece 9a. Adjust, and adjust in this way, then screw 8
The elongated rail 8b of the attachment piece 8a and the screw hole of the frame member 9 are tightened in a penetrating manner by c, so that the suspension rail 2 is attached to the frame member 9 in a vertically adjusted position. There is.

On the other hand, the rail side hanging metal fitting 10 is fixed to the inner slide rail 5 through the screw 10a.
The rail-side suspension rail 10 has a frame member 9 at the upper end edge.
An upper piece 10b is formed which is bent in a substantially L shape toward the side (rearward) and has a front end edge extended to the vicinity of the rear surface position of the suspension rail 2, and the suspension rail 2 is loosely fitted from the front. It is provided in the state to do. Furthermore, the rail side suspension rail 1
A hook portion 10c having a substantially U-shape is formed at the lower left and right lower ends of 0 to project downward. On the other hand, the door body 1
A door body side hanging metal fitting 11 is integrally provided on the upper surface of the door body corresponding to the hook portion 10c, and the pair of left and right hanging pieces 11a constituting the door body side hanging metal fitting 11 has a long length in the vertical direction. Each of the holes 11b is formed, and the locking pin 12 is supported in a state of penetrating the elongated holes 11b, and is retained by the retaining pin 12a from the elongated hole 11b. Then, the hook portion 10c of the rail-side hanging metal fitting 10 is locked to the locking pin 12 from below, so that the door body 1 is hung on the inner slide rail 5.

Here, the relationship between the hook portion 10c of the rail-side hanging metal fitting 10 and the locking pin 12 is set as follows. That is, the hook portion 1 formed in a substantially U shape
The inner diameter in the horizontal direction at 0c is set to be larger than the outer diameter of the locking pin 12, and the hook portion 10c
Are set so that their contact areas are small when they abut against the locking pin 12 from below and are locked. Further, in the present embodiment, the elongated hole 11b of the hanging piece 11a of the door-side hanging metal fitting 11 on which the locking pin 12 is supported.
The inner diameter in the horizontal direction is also set to be larger than the outer diameter of the locking pin 12, so that when the door 1 is suspended, the elongated hole 11b is located above the locking pin 12. The contact areas are set to be small when they abut each other. Reference numeral 20 is a self-closing device, 21 is a piston cylinder for shock absorbing when closed, and 22 and 23 are holding devices provided for shock absorbing when opening and starting and stopping the closing operation. Further, 24 is a retaining member provided on the upper surface of the door body 1.

In the embodiment of the present invention constructed as described above, the door body 1 is opened and closed while being suspended by the slide type suspension rail 2. In this embodiment, the door body 1 is opened and closed. When the door body 1 swings back and forth due to a load acting in the swinging direction, the rail-side hanging metal fitting 10
Since the inner diameter of the hook portion 10c of the door is larger than the outer diameter of the locking pin and the contact area with the locking pin 12 is small, the door body 1 swings in the front-back direction with the locking pin 12 as the axis. When moving, the sliding resistance between the locking pin 12 and the hook portion 10c becomes small. Therefore, even if the door body 1 is rocked by a load in the front-rear direction, the locking pin 12 smoothly rocks the inner surface of the hook portion 10c, so that It is possible to prevent applying a load in the front-back direction. As a result, the inner slide rail 5 is prevented from falling off without being concentrated on the groove fitting portions of the balls 6 and the outward guide groove portions 5a and 5b of the inner slide rail 5, which is highly reliable. Can be

Moreover, in this one, the locking pin 1
Since the contact area between the door 2 and the door-side hanging metal fitting 11 is also small, it swings when the locking pin 12 is rotated together with the door-body-side hanging metal fitting 11 which is rocked by the rocking of the door body 1. It is also prevented from moving and smoothly swings, whereby it is possible to more effectively prevent a load in the front-rear direction from acting on the rail-side suspension fitting 10.

Of course, the present invention is not limited to the above-mentioned first embodiment, and in short, the back and forth swing of the door body swings the rail-side hanging metal fitting through the locking pin. It is sufficient that the locking pin 12 and the hook portion are reversed from each other as in the second embodiment shown in FIG. A through hole 13b having a diameter larger than the diameter is formed, and the locking pin 12 is supported in the through hole 13b so as not to be pulled out.
It is also possible to form a hook portion 14a having an inner diameter larger than the outer diameter of the locking pin 12 and to lock the hook portion 14a to the locking pin 12 from above. However, the same effect as the first embodiment can be obtained. Further, as in the third embodiment shown in FIG. 5, the locking pin 15a may be integrally formed on the rail-side lifting metal fitting 15 instead of supporting the locking pin through the through hole provided in the hanging metal fitting. Well, by locking the hook portion 16a formed on the door-side suspension rail 16 to the locking pin 15a and having an inner diameter dimensioned larger than the outer diameter of the locking pin 12 from above, Although the same effect as that of the above-described embodiment can be obtained, in this case, the number of parts can be reduced and the mounting work can be simplified. Further, as in the fourth embodiment shown in FIG. 6, hanging pieces 17a and 18a are formed on the rail-side and door-side hanging metal fittings 17 and 18, respectively, and the locking pin 12 is attached to each hanging piece 17a and 18a. The same effect can be obtained by forming through holes 17b and 18b having an inner diameter larger than the outer diameter and allowing the locking pin 12 to pass through these hanging pieces 17a and 18a in a removable manner.

[0014]

In summary, since the present invention is constructed as described above, the locking pin for connecting and supporting the hanging rail and the door body is the locking hook of the hanging metal fitting for locking this. Since the outer diameter is smaller than the inner diameter of the locking hole, the contact area between the locking hook or locking hole and the locking pin is small, and the door body swings under the load in the front-back direction. In addition, the sliding resistance of the locking pin with respect to the locking hook or the locking hole is reduced, so that the locking pin can be swung smoothly. As a result, the back-and-forth swing of the door body is prevented from acting on the inner slide rail as a load, and the inner slide rail can be prevented from falling off, which makes it highly reliable.
