Description

[Detailed description of the invention] The present invention relates to the structure of a door section in a flexible door, and in particular, the invention relates to a door section structure of a flexible door, and in particular, a flexible door in which the interval between the two leg plates is gradually narrowed on the lower side, and the legs are fitted to each other so as to be slidable up and down. This relates to the structure of the door section.

The door section of this type of swivel door is made by processing the necessary parts such as suspension, operation string through holes, upper and lower door section locking hooks, and hook hooks on a single steel plate, and then bending both legs. It has been proposed to form the door section into a roughly gate-shaped shape, but since the distance between the legs must be different for each door section, the steel plates should be made with different widths depending on the width of the gap between the legs. It is necessary to use a It is difficult to process, difficult to mass produce, and requires the use of a special bender.

In view of the above-mentioned circumstances, the present invention was devised to eliminate these drawbacks, and consists of both leg plates and a separate top plate formed to correspond to the predetermined width of the step. An object of the present invention is to provide a door section structure for a flexible door that allows door sections with different distances between both legs to be easily mass-produced without using a special bender by connecting and fixing the door sections and assembling them. The technical means for this purpose is that the door sections of multiple upper and lower stages are formed in a substantially gate-shaped cross section, and the opposing distance between the leg plates is gradually narrowed toward the lower stages.
In a flexible door configured to be vertically extendable and retractable, each leg plate of each stage is formed with a hook hook at the upper end and a locking hook at the lower end. The door section of the tier includes a fixed part formed by bending the upper part of the leg plate, and a side edge of a top plate that corresponds to the predetermined width of each tier and is approximately the same length as the longitudinal dimension of the leg plate and is formed separately. They are characterized in that they are connected and fixed so that they can be fitted sequentially in the vertical direction.

The structure of the present invention will be explained based on the embodiment shown in the drawings. Reference numeral 1 is a flexible door composed of a plurality of door sections 2 implementing the present invention,
A winding shaft 3 of the flexible door 1 is horizontally mounted within a case 4 fixed to the upper edge of an opening of a building. A motor 5 is interlocked and connected to an intermediate portion of the winding shaft 3, so that the winding shaft 3 can be freely rotated in forward and reverse directions.

As shown in FIG. 5, the door section 2 has a substantially gantry-shaped cross-sectional configuration with left and right leg plates 6 and a top plate 7 connecting the upper edges of the leg plates 6. A locking hook 6a is formed by bending the lower end of the locking hook 6 inward. The locking hook 6a has a support 8b that supports a roller shaft 8a on which the roller 8 is rotatably supported.
are fitted and fixed at a predetermined interval in the longitudinal direction.

On the other hand, on the upper end side of both leg portions 6, there is a horizontal portion 6b bent inward at an acute angle.
A fixing portion 6c is formed vertically bent upward from the corner portion 6d, and a locking hook 6a is provided at the corner portion 6d bent at an acute angle at a position facing the adjacent roller shaft 8a. An engageable hook 6e is cut and raised outward, and is further bent downward.

Fixing parts 7a are formed on both side edges of the top plate 7 and are bent vertically upwards, and are brought into contact with the fixing parts 6c of both leg plates 6 and fixed as appropriate by screwing or stitching. The door section 2 is fixed by means of the structure of the corner portion 6d.
The width tapers at the bottom. Further, the width A of the top plate 7 is made to differ by a predetermined width for each door section 2, and by sequentially changing the facing distance between the leg plates 6 in each door section 2, the width A of the top plate 7 is changed from the wide door section 2 to the narrow door section 2. are sequentially fitted in a vertically slidable manner, and the flexible door 1 is configured to be extendable and retractable by vertically sliding.

As shown in FIG. 3, the widest door section 2a of the door sections 2 is suspended from the case 4 via a hanging wire 9. As shown in FIG. On the other hand, the narrowest door section 2 has a seat plate 10.
A plurality of actuating wires 11, each having one end fixed to the seat plate 10, pass through through holes 7b and 4a formed in the top plate 7 and case 4 of each door section 2, respectively, and are wound. It is wound around a take-up drum 12 provided on the take-up shaft 3. Guide rails 13 are fixed to both ends of the case 4 to guide the movable door 1 up and down.

Incidentally, the lifting and lowering of the universal door 1 is performed by driving the motor 5 by an elevator control mechanism (not shown), but if an obstacle is encountered during the lowering operation of the adjustable door 1, the seat plate 10 detects the obstacle. By providing a sensor, it can be stopped automatically.

Next, the operation of the present invention configured as described above is as follows.
The explanation will be based on the process of assembling the adjustable door 1.
First, in order to form the door section 2, the leg plates 6 and the top plate 7 are formed into a predetermined shape, and then these are connected and fixed. That is, as shown in FIG. 6, the leg plate 6 is formed by bending a locking hook 6a, a horizontal portion 6b, and a fixing portion 6c on a steel plate B using a roll forming machine, a bender, or the like.
A plurality of supports 8b are fitted and fixed to the locking hook 6a so that the adjacent rollers 8 are positioned at a predetermined interval, and then the hooks are attached to the corner portions 6d in alignment with the positions facing the adjacent rollers 8. Attendant 6e
It can be formed by cutting and bending.

On the other hand, the top plate 7 is formed by forming fixing portions 7a using a bender or the like on both side edges of steel plates C whose widths differ by a predetermined width sequentially, and by punching through holes 7b using a press or the like. be able to. Then, the leg plate 6 and the top plate 7 formed in this manner are fixed with appropriate fixing means such as fixing with screws or caulking using a stitching machine with the respective fixing parts 6c and 7a facing each other to form the door section 2. Can be done. Therefore, as in the case where the door section 2 is formed from a single steel plate, the steel plate on which the locking hook 6a, hook catch 6e, etc. are formed is made using a special bender so as not to affect the hook catch 6e, etc. Furthermore, the leg plate 6 does not have to be formed by bending the long leg while changing the bending position, but the leg plate 6 is a mass-produced one that is common to each door section 2. In addition, the top plate 7 is formed by bending the fixing parts 7a on both side edges, but as in the case where the door section 2 is formed from a single steel plate, it is possible to Unlike the one that is bent so as not to affect the hook holder 6e, etc., the fixed part 7 has a short leg on the flat steel plate C.
Since it is only necessary to bend a, it can be formed without using a special bender.

When the door sections 2 formed in this manner are combined, the adjustable door 1 is constructed. In order to lower the adjustable door 1, the motor 5 may be operated, the winding shaft 3 may be rotated, and the operating wire 11 may be rewound. That is, as sequentially shown in FIG. 4, by unwinding the actuating wire 11, the collapsible door 1 is first lowered from the open position where it contacts the case 4 to the position where the hanging wire 9 is stretched and tensioned. do. When the actuation wire 11 is further unwound, the most adjacent lower door section 2 fitted to the uppermost door section 2a is moved, and both side plates 6 of the lower door section 2 are connected to the upper door section 2.
It further descends together with the lower door section 2 while being guided by the rollers 8 of a. When the locking hook 6a of the lower door section 2 is locked with the hook catch 6e of the upper door section 2a, the lower door section 2 is integrally locked with the upper door section 2a. As described above, by rewinding the actuating wire 11, the hook 6e is successively engaged with the locking hook 6a of the door section 2 from the upper stage side to the lower stage side, and the flexible door 1 is lowered and closed. be done.
On the other hand, to open the adjustable door 1, the motor 5 may be rotated in reverse to wind up the operating wire 11.

Here, since the door section 2 of the present invention is formed by fixing the leg plates 6 and the top plate 7, if the top plate 7 is made of a material such as a hard synthetic resin with low thermal conductivity, The adjustable door 1 has a double door type with an air layer in the middle, and can be expected to have excellent heat insulation performance. However, when the top plate 7 is made of a material such as hard synthetic resin,
There is a risk that the fixing part between the top plate 7 and the leg plate 6 may be damaged, or the top plate 7 itself may be damaged, causing an abnormal situation such as the top plate 7 falling off. Since it is provided on the leg plate 6 side rather than on the plate 7 side, even if an abnormal situation occurs in which the top plate 7 falls off, the top plate 7 simply connects both leg plates 6 in a bridging state. Because of this, the door section 2 at the location where the top plate 7 has fallen will not fall and be damaged, and the swivel door 1 will always be held continuously up to the lowest door section 2.

In addition, in the door section 2 of the above embodiment, since the distance between the two leg plates 6 is narrower toward the bottom, the leg plates 6 are connected to the two leg plates 6 of the lower door section 2 when the adjustable door 1 is closed. As a result, the legs are forcibly opened in a substantially parallel manner, and therefore, there is no possibility of a locking error between the locking hook 6a and the hook catcher 6e.

Furthermore, the structure of the fixing portion between both leg plates 6 and the top plate 7 is such that the fixing portions 6c and 7a are vertically shaped as in the above embodiment.
For example, as shown in FIG. 7A, the side edge of the horizontal plane with the fixing part 7a of the top plate 7 as a reinforcing part and the leg plate 6
The horizontal portions 6b of the leg plate 6 may be bent and fixed directly as fixing portions to lower the height.Alternatively, as shown in FIGS. The fixing portion 7a of the top plate 7 may be connected and fixed in various interlock shapes to ensure the connection.

In summary, the present invention has a plurality of upper and lower door sections, each of which has a substantially gate-shaped cross section, and the facing interval between the two leg plates is gradually narrowed toward the bottom.
In a flexible door configured to be vertically extendable and retractable, each leg plate of each stage is formed with a hook hook at the upper end and a locking hook at the lower end. The door section of the tier includes a fixed part formed by bending the upper part of the leg plate, and a side edge of a top plate that corresponds to the predetermined width of each tier and is approximately the same length as the longitudinal dimension of the leg plate and is formed separately. Since they are connected and fixed so that they can be fitted in the vertical direction sequentially, they are each provided with locking means at the top and bottom, and the lower door section is slidably fitted into the upper door section to open and close. Although it is a swivel door, the door section is shaped like a gate.
In particular, since it is formed by both leg plates and a top plate that is separate from the leg plates, the bending position of the single steel plate with hooks etc. formed must be changed one by one using a special bender. However, there is no need to form long legs, the leg plate can be used commonly for all door sections, and a plurality of door sections with different distances between the legs can be easily mass-produced. Moreover, since the top plate can be formed using a different material from the leg plates, for example, if the top plate is made of a material with low thermal conductivity such as hard synthetic resin, it can be made with extremely good heat insulation properties. It can also be a free door. In addition, the hooks are not formed on a separate top plate, but are attached to both leg plates on which locking hooks are formed, so even if an abnormal situation occurs where the top plate falls off, The swivel door does not fall from the falling part of the top plate, and has the advantage of always being maintained continuously up to the lowest door section.
