Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing door, and more particularly to an opening / closing door for application to a large frontage portion formed in a large building such as a warehouse, a large store or a factory.

[0002]

2. Description of the Related Art Various doors have been proposed and used in the past for opening and closing a large frontal opening of a large building such as a factory. The difference is that the door main body has a very large area to cover the frontage. As a general structure of a door that opens and closes such an opening, firstly, a large door is directly hung and slid horizontally, and secondly, a so-called shutter is used. is there.

Since the sliding door is to be opened by moving it to the front of the wall surface of the building located on both sides of the frontage, it is necessary for the building to have a wall surface about the length of this door. It cannot be used when the frontage is larger than half the length of the building. Further, since this sliding type door is stored along the wall surface, it is completely useless when the frontage is opened. Moreover, when the frontage area becomes large, this sliding door must be very heavy in order to withstand wind pressure, etc., and a considerable amount of force is required to open and close it. It becomes very difficult to open and close because the operation time becomes long and the operation time becomes long.
On the other hand, a shutter type door requires not only a very large space or a device for winding it, but also an opening and closing operation time becomes long as the frontage becomes very large. There is not much merit to use.

Further, it is necessary to be very careful in forming a door for this type of large frontage, since the door itself has a large area, the wind pressure received by it is considerably large. That is. In other words, it is necessary to have a structure that can reliably fix the large-area door when it is closed.
Therefore, the present inventors have variously studied how to configure the door for opening and closing the large frontage of the building while avoiding the above-mentioned problems, and as a result, The invention was completed.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and the problem to be solved is how to solve the problem of a door for opening and closing the frontage of a large building. It will be configured without. And, the purpose of the present invention, when applied to the Oma frontage,
Not only can the opening and closing operations be performed reliably and in a short time, but it can also be securely fixed to the building when it is closed, and the opening and closing door that can also be used as the eaves of the building when opened has a simple structure. To do.

[0006]

Means for Solving the Problems In order to solve the above problems, the means adopted by the present invention will be described with reference to the reference numerals used in the embodiments. An opening / closing door 20 for covering a large frontage portion 11, which has a size to cover the frontage portion 11, and is folded at at least one lateral bending portion 22, and a frontage portion. Rails 2 fixed vertically on both sides of 11 to fix the door body 21 when closed and guide it when opened.
3, a connection support member 24 that rotatably connects the left and right upper ends of the door body 21 to the upper end side of the rail 23, and a moving support member that is connected to the left and right lower ends of the door body 21 and moves vertically on the rail 23. 25 and a drive mechanism 26 for moving the moving support member 25 up and down. When the moving support member 25 is moved upward by operating the drive mechanism 26,
The opening / closing door 20 is characterized in that the door body 21 is also folded at least in two above the frontage portion 11 to form an eaves.

[0007]

The operation of the opening / closing door 20 according to the present invention constructed as above will be described below together with the mode of use thereof. First, when the opening / closing door 20 completely covers the frontage part 11 of the building 10 as shown in FIGS. 1, 3 and 4, both side ends of the opening / closing door 20 are It is firmly held by the rail 23 fixed to the side. That is, as shown in FIG. 4, on the upper end side of the door main body 21, the connection support members 24 integrally provided at the left and right ends of the door main body 21 are firmly attached to the upper end sides of the rails 23, though they are rotatable. On the other hand, on the lower end side of the door main body 21, on the other hand, the moving support members 25 integrally provided on the left and right ends of the door main body 21 are firmly held on the lower end sides of the rails 23, respectively. As a result, the four corners of the door body 21 are firmly held around the frontage part 11 of the building 10. Therefore, even if the door body 21 receives negative pressure due to wind pressure or wind,
The door body 21 maintains a state of being firmly supported by the building 10 side.

In this case, in the opening / closing door 20 according to the second embodiment of the present invention shown in FIGS. 5 to 8, as shown in FIG. 7, the bent portion 22 and the lower end of the door body 21 have a cross section. Since the trusses 27 have a triangular shape, one surface of each of the trusses 27 abuts on the base side at the lower end of the door body 21 and at the bent portion 22 of the door body 21. .. Therefore, when the opening / closing door 20 is in the closed state shown in FIG. 7, the respective trusses 27 are in contact with the other portions, so that the closed state of the entire door main body 21 is firmly held by the respective trusses 27. Is done.

If it is desired to further strengthen the support of the opening / closing door 20 with respect to the building 10, the bent portion 22 is provided.
It suffices to fix the vicinity of both ends to each rail 23 side by another fixing member, and in this case, as the fixing member, one that can be remotely operated by electric power, hydraulic pressure or a wire may be adopted.

When it is desired to release the closed door 20, the drive mechanism 26 is operated by operating a switch 26a provided near the frontage 11 of the building 10, for example.
Drive. In the drive mechanism 26, when the drive member 26c connected to the movement support member 25 is a cord, the drive member 26c is connected to the drive motor 26b.
Each moving member 25 connected to this driving member 26c is moved upward on the rail 23 by pulling up by the rotational driving of the driving member 26c. When the driving member 26c is a screw bolt, the driving member 26c is driven. Motor 26b
The movable support member 25 screwed to the drive member 26c is moved upward. The same applies to a drive mechanism that uses hydraulic pressure and that allows each moving member 25 to move upward on the rail 23. In any case, when the drive mechanism 26 is driven by the switch 26a, the respective movement support members 25 integrated with the door body 21 by the drive member 26c are moved to the respective rails as shown by the chain double-dashed line in FIG. It moves up while being guided by 23. In this case, the door main body 21 is bent by at least one bending portion 22, and the upper end side of the door main body 21 is connected to each of the connection support members 2 by the bending.
It turns at 4.

When each moving support member 25 is moved to the upper end side of each rail 23 by the drive mechanism 26 as described above, as shown in FIG. 2 or FIG. It will be completely released. At this time, the important thing is that the door body 21 of the opening / closing door 20 is folded at the bent portion 22 as shown in FIG. 2, FIG. 4 or FIG. The operation is performed within a short time as compared with the case where the door body 2 is folded or wound.
1 is to form an eaves above the frontage portion 11. Since the rain and snow are blocked by the folded door body 21, it is possible to load and unload cargo under the door body 21 without getting wet.

Further, as described above, the opening operation of the opening / closing door 20 is performed only in front of the frontage part 11 of the building 10, so that the door body 21 when the building 10 itself is opened.
Since there is no need for a space to store the door, even if the frontage portion 11 has a width of ½ or more of the width of the building 10, it does not affect the opening / closing operation of the door body 21.

In the opening / closing door 20 according to the embodiment described below, as shown in FIGS. 4 and 8, the door body 21 has an upper portion with one bent portion 22 as the center. It is divided so that it is slightly larger. As a result, when the door body 21 is folded and opened, as shown in FIG. 4 or FIG.
5 is formed into a triangular shape having one base as a base, and thereby, the support of the door body 21 in the open state with respect to the building 10 side is further strengthened. Further, in the opening / closing door 20 according to the second embodiment, as shown in FIG. 8, there is a truss 27 that can be inserted between the folded door bodies 21, and the truss 27 of the folded door body 21. The interval is kept constant.

Of course, in order to close the opened open / close door 20, the drive of the drive motor 26b of the drive mechanism 26 described above may be reversed. In that case, the state opposite to that described above is required. It goes without saying that the opening / closing door 20 is closed by.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the opening / closing door 20 according to the present invention as described above will be explained according to the embodiments shown in the drawings.
It is as follows. Example 1 FIGS. 1 to 4 show the opening / closing door 20 according to the first example of the present invention.
The opening / closing door 20 is configured such that the door body 21 can be folded in two at a bending portion 22 formed in a horizontal direction at a substantially central portion. In addition, in addition, this door body 2
It is conceivable to fold 1 into four or six, but in that case, the bent portions 22 are formed into three, five, etc., and the building inside these folded portions 22 1
For the one on the 0 side, a movement support member 25 described later is provided.
It is good to integrate each.

It is natural that the door main body 21 has a sufficient area to cover the entire frontage part 11 of the building 10 when completely expanded, but the door main body of the present embodiment. In FIG. 4, in order to prevent the escape of air when the frontage part 11 is closed, the lower end edge of the door body 21 is
A rubber plate 21c is attached as shown in FIG. Also,
In this door body 21, as shown in FIG. 1, necessary windows 21a and doors 21b are integrally formed in the lower portion of the bent portion 22, so that the lighting and the entrance / exit at the time of closing can be achieved. I am able to secure it. Of course, this door body 2
As shown in FIG. 3, 1 is formed by forming a framework by using a steel frame material or the like, and attaching a cover material to the surface of this framework, etc. The rigidity of the door body 21 itself can sufficiently withstand wind pressure and the like.

In the opening / closing door 20 of this embodiment, the connecting support members 24 are integrally provided at the upper left and right portions of the door body 21 described above, and at the lower left and right portions of the door body 21. The movement support member 25 is integrally provided. Each connection support member 24 is a rail 23 in the vertical direction fixed to the side of the building 10 located on the left and right of the frontage portion 11.
Is connected to the upper end of the rail 23, while each movement support member 25 is connected to the drive member 26c in the rail 23.

The drive member 26c constitutes the drive mechanism 26 for opening / closing the opening / closing door 20.
It is driven by a drive motor 26b provided in a part of 0. That is, the drive member 26c may be implemented simply as a cord connected to each moving support member 25, or may be implemented as a screw bolt screwed into each moving support member 25. Therefore, when the drive member 26c is a cord, it is necessary to configure the drive mechanism 26 so as to wind it up.
If c is a screw bolt, it is necessary to configure the drive mechanism 26 to rotate the screw bolt. The drive motor 26b of the drive mechanism 26 may be an electric type or a hydraulic type, and the switch 26a for operating the drive motor 26b is, as shown in FIG. It is provided on the side of the building 10 located near the frontage part 11.
Of course, since each moving support member 25 may be moved up and down with respect to the rail 23, the drive mechanism 26 for moving the rail 23 up and down is of the electric type or the hydraulic type as described above. Alternatively, either mechanical one can be adopted.

Embodiment 2 FIGS. 5 to 8 show an opening / closing door 20 according to a second embodiment of the present invention.
In this opening / closing door 20, the door body 21
The door is substantially the same as the opening / closing door 20 according to the first embodiment described above except that the truss 27 is used as the structural material. Therefore, in this second embodiment, the same members as those of the opening / closing door 20 according to the first embodiment described above are designated by the same reference numerals in FIGS.

In the opening / closing door 20 of the second embodiment,
The trusses 27 as shown in FIG. 6 are used for the important parts, and specifically, these trusses 27 are used in the places as shown in FIGS. 7 and 8. .. That is, first, the pair of trusses 27 are attached to the door body 21.
The left half of FIG. 5 and FIG.
Further, as shown in FIG. 8, the bent portion 22 is configured, and by adopting one truss 27 at the lower end of the door main body 21, it is possible to make contact with the base when the door main body 21 is closed. Is done. Further, one truss 27 is also used on the inner surface side of the door main body 22 which is the upper side of the bent portion 22, and the truss 27 has a space between the door main bodies 21 folded in two as shown in FIG. Is a predetermined value (the height of the truss 27)
It is something that I try to maintain. And these four trusses 27 make the rigidity of the whole door main body 21 sufficient.

In particular, the two trusses 27 for forming the bent portion 22 play an important role when the frontage portion 11 is closed by the opening / closing door 20. That is, as shown in FIG. 7, each truss 27 is formed so that the cross sections thereof both form a right triangle, and one side sandwiching a right angle abuts each other. is there. As a result, the front portion 11 by the opening / closing door 20
When closed, the door body 21 has extremely high rigidity due to the abutment of the trusses 27 forming the bent portion 22 with each other.
