JPH08177301A - Runoff preventive device for inside slide rail in top-railed sliding door - Google Patents

Abstract

PURPOSE: To prevent the runoff of an inside slide rail by interposing a reinforcing member between an outside slide rail and a frame member, and by providing runoff preventive extended sides for preventing the runoff of the inside slide rail with both the upper and lower end peripheral parts of the reinforcing member. CONSTITUTION: In the case where a door body 1 is opened or closed in such a state that it has been suspended by a hanging rail 2, the runoff preventive extended sides 11b, 11c of a reinforcing member 11 detour around an outside slide rail 4 from the upper and lower outsides and are extended to a hanging member fitting surface 5c beyond the corresponding positions of guide grooves 5a, 5b that have been outwardly formed on the upper and lower sides of an inside slide rail 5. Even if a load is applied to the inside slide rail 5 in the direction it is run off from balls 6 by the oscillation or the like of the door body 1, the hanging member fitting surface 5c of the inside slide rail 5 abuts on the runoff preventive extended sides 11b, 11c, so that the falling of the door body 1 can be prevented. Thus, there is no possibility that the inside slide rail 5 is run off and the door body 1 is dropped.

Detailed Description of the Invention

[0001]

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 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 body side are locked by 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 an 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.

[0004]

SUMMARY OF THE INVENTION The present invention was devised with the object of providing an apparatus for preventing the inner slide rail from slipping off in a hanging door that can eliminate these drawbacks in view of the above circumstances. It is supported by a retainer between the inward guide grooves above and below the outer slide rail that is integrally attached to the frame side and the outward guide grooves above and below the inner slide rail that supports the door body. In a hanging door in which the door body is hung openably and closably using a slide-type hanging rail having a ball rotatably interposed therein, the outer slide rail and a frame to which the outer slide rail is attached A reinforcing member is interposed between the upper and lower members, and upper and lower inward guide groove portions of the outer slide rail are detoured from the upper and lower sides at the upper and lower end edges of the reinforcing member. And it is characterized in that a vertical outward guide groove closely opposed to the latch for the extension side of the anti-removal of the inner slide rail to the hanger mounting surface located between the inner slide rail.

According to the present invention, it is possible to prevent the inner slide rail from falling off due to the swinging of the door body in the front-rear direction.

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 rear surface of the outer slide rail 4 is covered with a reinforcing member 11 having a substantially C shape, which will be described later, and the rear surface of the reinforcing member 11 is fixed to the rail receiving member 8 by a screw 4c. By attaching to the frame member 9 on the body side in this state, the suspension rail 2 can be attached to the body side. By the way, the rail receiving member 8 is attached to the frame member 9 by forming a long hole 8b which is long in the up-down direction in the attaching piece 8a protruding from the upper edge portion of the rail receiving member 8. Is formed with a supporting piece 9a for supporting the lower surface of the frame receiving member 8, and a screw 9c is provided in a screw hole 9b formed in the supporting piece 9a.

The suspension rail 2 is configured to be attached to the frame member 9 with its position adjusted in the vertical direction.

By the way, although the present invention is applied to the reinforcing member 11, the reinforcing member 11 is applied to the rear surface of the outer slide rail 5 as described above.
And the upper and lower retaining edges 11b and 11c extending from both upper and lower edges of the reinforcing portion 11a. The retaining edges 11b and 11c are located inside and below the outer slide rail 5, respectively. By attaching the hanging metal fittings provided between the outward guide grooves 5a, 5b by bypassing the outward guide grooves 5a, 5b from above and below and beyond the positions corresponding to the upper and lower outward guide grooves 5a, 5b of the inner slide rail 5. Surface 5c
The inner slide rail 5 has been extended to reach
Is trying to fall off the outer slide rail 4,
The hanging bracket mounting surface 5c of the inner slide rail 5 is dimensioned so as not to come off by coming into contact with the detachment preventing extension sides 11b and 11c. On the other hand, the hanging metal fitting 10 is fixed to the hanging metal fitting surface 5c through the screw 10a, and the upper end of the hanging metal fitting 10 extends beyond the upper anti-slip extension side 11b. On the other hand, it is attached so as to closely face the upper and lower detachment extension sides 11b and 11c. Further, substantially L-shaped fastening portions 10b are provided at the lower left and right lower ends of the hanging metal fitting 10 so as to project downward, and the fastening portions 10b are fastened to the upper surface of the door body 1. The suspension rail 2 and the door 1 are connected with each other. Reference numeral 12 is a self-closing device, 13 is a piston cylinder for shock absorbing when closed, and 14 and 15 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 opened and closed while being suspended by the suspension rail 2. In this case, the reinforcement member 11 is provided with a retaining extension. Since the sides 11b and 11c detour from the upper and lower outer sides of the outer slide rail 4 and extend beyond the upper and lower outward guide grooves 5a and 5b corresponding positions of the inner slide rail 5 to reach the hanging metal fitting mounting surface 5c, Even if a load acts on the inner slide rail 5 to drop from the balls 6 due to swinging of the door body 1 or the like, the hanging metal fitting mounting surface 5c of the inner slide rail 5 contacts the slip-off preventing extension sides 11b and 11c. It will be possible to measure the fallout, and by this,
The inner slide rail 5 does not fall off and the door body 1 does not fall.

Moreover, in this one, the hanging metal fitting 10 is
Since the extension sides 11b and 11c of the reinforcement member 11 for reinforcing the suspension rail 2 are closely opposed to each other,
When a load in the front-rear direction acts and the door body 1 tries to swing in the front-rear direction, the hanging metal fitting 10 is provided with the extension side 1 for preventing the upper and lower detachments.
By contacting with 1b and 11c, further forward and backward swinging is restricted. As a result, the swinging of the door body 1 in the front-rear direction is prevented, the load on the inner slide rail 5 can be reduced, and the outward guide grooves 5a and 5b above and below the inner slide rail 5 can be reduced. The load is not concentrated on the groove fitting part between the ball 6 and the ball 6,
As a result, the inner slide rail 5 is prevented from falling off, and the reliability can be increased.

[0012]

In summary, since the present invention is constructed as described above, the slide type suspension rail is attached to the body side by fixing the outer slide rail to the frame member through the reinforcing member. At the upper and lower edges of this reinforcing member, the outer slide rail is detoured from the upper and lower sides to prevent the slippage from reaching the hanging metal fitting mounting surface formed between the upper and lower outward guide grooves of the inner slide rail. Since the extended side for use is formed, even if there is a swing in the door body and a load acts on the inner slide rail to fall off the ball, the inner slide rail will come in contact with the extended side for preventing slippage and fall off. It is possible to prevent the door body from dropping due to the inner slide rails falling off.
