Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a steady rest device for a hanging door that opens and closes in the left-right direction while being suspended from a hanging rail installed on the upper edge of an opening.

[Problems to be solved by the prior art and the invention] In general, some openings such as entrances and exits of buildings are constructed so that the hanging door can be opened and closed in the left and right directions while being suspended from a hanging rail laid on the upper edge of the opening. There is something I did. By the way, in this case, as shown in Figure 9, the hanging door is only suspended at the upper edge, so there is a problem that it inevitably swings back and forth when opening/closing or when it is fanned by the wind. be.

Therefore, as shown in FIG. 8, a concave groove-shaped steady rest is provided on the lower edge of the hanging door, and the steady rest is guided by a steady rest rail laid on the floor or ground.
This was used to prevent the hanging door from swinging. However, in this case, since the steady rest rail is laid on the floor surface, etc., the smoothness of the floor surface etc. is inevitably impaired, and the smooth movement of vehicles such as trolleys should not be allowed to be hindered. There are problems such as mud and pebbles becoming clogged and preventing the door from opening and closing smoothly.

Therefore, as shown in Utility Model Application Publication No. 56-112382,
While a locking rail is integrally provided on the side wall of the frame,
Some hanging doors are provided with a locking receiving member that locks the locking rail so as to be movable in the left and right direction, thereby preventing the hanging door from swinging. However, in this case, when the hanging door is fully closed, the locking receiving member only locks on the locking rail in a small area where the wall surface and the hanging door overlap. As a result, if the overlapping area between the wall and the hanging door is narrow in the fully closed state, it is difficult to provide an effective steady rest function. However, in the former case, the hanging door becomes larger, and in the latter case, the opening width becomes narrower and the function of the opening becomes smaller. There is a problem with the decline.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a steady rest device for a hanging door that can eliminate these drawbacks. In a hanging door configured to open and close in the left and right directions while being suspended from a hanging rail laid on the upper edge of an opening on the side of the body, a locking rail is provided on a wall surface on the side of the body in which the hanging door is housed when the door is opened. At the same time, the hanging door is equipped with a locking receiving member that slides in the left and right direction while being locked to the locking rail to prevent the hanging door from swinging. In the closed state,
The hanging door is characterized by being long in the left and right directions from a protruding position that protrudes in the storage direction from the door end position to a middle part of the hanging door that is closer to the door end than the opening edge. It is something.

With this configuration, the present invention enables reliable steadying without narrowing the opening or widening the horizontal width of the hanging door.

[Example] Next, the present invention will be described based on an example shown in the drawings. In the drawing, reference numeral 1 denotes a frame of a warehouse, etc. A hanging rail 2 is laid on the upper edge of an opening formed in the frame 1, and a hanging roller 4 provided on the upper edge of a hanging door 3 is installed. By rolling on the hanging rail 2, the hanging door 3 can be opened and closed in the left and right directions. The lower half of the wall 5 constituting the frame 1 is formed by stacking concrete blocks, and when covered by the flaw material 6 pasted on the wall 5, it is shaped like a C and becomes female. A locking rail 7 serving as a strip is horizontally installed integrally with a plurality of locking screws 8 in a state where the hanging door side is open. Furthermore, 9
are a plurality of buried screws embedded in the concrete block, into which the locking screws 8 are screwed.

On the other hand, a locking receiving member 10 having a substantially C shape and having a male strip is integrally fixed to the hanging door 3 with a locking screw 11 in a state that opens toward the wall surface 5. The retaining member 10 is loosely fitted into the retaining rail 7 so as to be movable in the left-right direction while being secured against the retaining rail 7 in the front-rear direction. In addition, 12 is a rubber plate provided to close the opening of the lock receiving member 10;
13 is a collar interposed between the lock receiving member 10 and the hanging door 3.

The lock receiving member 10 is formed of a long material that is long in the left-right direction, but in this embodiment, one end is located outside the end edge of the hanging door 3, that is, at the hanging door. It further protrudes toward the storing direction side of the door 3 and is set so that the other end is located at approximately the center position of the hanging door 3. When the hanging door 3 is fully closed, the part of the lock receiving member 10 that protrudes from the end edge of the door is locked to the lock rail 7 by a width L, as shown in FIG. The hanging door 3 is designed to be secured against the steady rest.

In the embodiment of the present invention configured as described above, the hanging door 3 has a lock receiving member 10 that is connected to the lock rail 7.
Since it is locked in a state in which it is locked in the front-back direction, it is prevented from steadying in the front-back direction. However, it has become a wide range of things. In other words, in this case, one end of the lock receiving member 10 protrudes outward from the bottom end of the hanging door 3 and is locked to the lock rail 7 over a wide area. As a result, the lock receiving member 10 receives a strong and reliable locking action in the longitudinal direction even if there is almost no overlap between the hanging door 3 and the wall surface 5.

Moreover, since this locking receiving member 10 is integrally provided with the hanging door 3 so as to reach approximately the center position of the hanging door 3, the locking action on the locking receiving member 10 in the front and rear direction is Since it acts on the central part of the hanging door 3, the steady resting effect in the front and back direction of the hanging door 3 is similar to that of the conventional hanging door and the wall surface 5 that only overlaps with each other. It is effectively avoided that the hanging door 3 is unevenly distributed only on the door end side.As a result, the hanging door 3 has the opening width of the opening as wide as possible to enhance the function of the opening, and Even if the hanging door 3 is miniaturized by reducing the horizontal width as much as possible, the hanging door 3 can be surely prevented from swinging.

Moreover, this structure is even more convenient because it is designed to prevent rainwater from entering the locking rail 7 and the locking receiving member 10.

It should be noted that the present invention is of course not limited to the above-mentioned embodiments, and may be constructed, for example, as in the second embodiment shown in Figs. 5 to 7 or the third embodiment shown in Fig. 10. You can.

That is, in the second embodiment, the lock receiving member 10 is provided on the hanging door 3 so as to be slidable in the left and right direction. Therefore, a long hole 14 is formed in the lock receiving member 10 in the left-right direction, and the collar 13, which is fitted onto the left and right locking screws 11 protruding from the hanging door 3, is secured to the long hole 14. It is meant to be slidably penetrated. And in this one, hanging door 3
When the door moves in the fully closed direction, the collar 13 on the door end side touches the door end side end 14a of the elongated hole 14 and moves together with the lock receiving member 10, and when it moves in the fully open direction, the door end side collar 13 abuts against the door end side end 14a of the elongated hole 14 and moves together with the lock receiving member 10. Collar 13 is long hole 14
It is set to move together with the lock receiving member 10 in a state where it abuts against the door end side end 14b. The opposing interval between the left and right locking screws 11 is set to be shorter than the long hole 14, so that when the hanging door 3 is fully closed, the locking receiving member 10 is As in the case of the example, the hanging door 3 is
The hanging door 3 can be firmly and reliably rested. on the other hand,
When the hanging door 3 is in the fully open state, the lock receiving member 10 slides from the fully closed state and is stored within the left and right width of the hanging door 3, and does not protrude from the door end side.
This eliminates the problem of the locking receiving member protruding from the door end and getting in the way when the door is fully opened, as in the first embodiment in which the locking receiving member was fixed to the hanging door. It has the advantage of being convenient.

Further, in the third embodiment, the lock receiving member 10 is integrally fixed to the hanging door 3, as in the first embodiment, but in this case, the lock receiving member 10 is integrally fixed to the hanging door 3.
Also, the shape of the lock receiving member 10 is changed, and it goes without saying that the present invention can also be implemented in this manner.

[Operation and Effect] In summary, since the present invention is constructed as described above, the hanging door can be rested by the locking rail provided on the wall side and the locking receiving member provided on the hanging door side. However, the locking receiving part is long in the left and right direction, and when the door is fully closed, the part that protrudes from the end of the door toward the storage direction is locked to the locking rail, and the opening is closed. It extends to the middle of the hanging door, which is closer to the door than the edge of the door. As a result,
Even if the overlap between the end of the hanging door and the wall surface is narrow when the hanging door is fully closed, the part of the locking receiving member that protrudes from the end of the door provides a long and reliable retainer against the locking rail. The locking action works all the way to the middle part of the hanging door, and the locking action only works in a narrow area such as the area where the conventional wall surface and hanging door overlap. This prevents the hanging door from becoming unstable, unlike when it works in a state where it is greatly biased, and it is possible to securely and firmly stabilize the hanging door.
