Description

[Detailed description of the invention] This invention is a movable center pillar device that is installed in the middle of a shutter curtain when the shutter curtain is lowered in a shutter in which two or more shutter curtains are installed at the frontage of a building such as an entrance. This is related to.

The movable center column in a shutter can be moved between the standing position and the storage position using a hanger rail, but conventional movable center columns are movably suspended from a single hanger rail. Because I am doing
During its movement, the middle pillar may rotate carelessly using the suspension part as a fulcrum or swing back and forth. There were drawbacks such as the need for operations such as corrections, which were not easy to perform.

The present invention aims to eliminate the drawbacks in view of the conventional situation as described above.
A movable middle pillar device for a shutter in which a hanger roller attached to the upper part of the middle pillar is rolled and movably hung on a hanger rail provided along the shutter curtain storage opening of the shutter case. A pair of front and rear pillars are provided in parallel with the storage opening, and the middle pillar is divided into an upper side including the front and rear hanging parts above it, and a lower side. By configuring the lower part to be able to pivot 90 degrees in the horizontal direction as a rotational fulcrum, the middle column suspended from the front and rear pair of hanger rails can be moved while always maintaining a predetermined direction. When the shutter curtain is opened, the middle pillar can be pivoted horizontally by 90 degrees to allow it to be stored neatly along the wall or pillar surface. The movable center column device is equipped with a latch mechanism and its engagement detection mechanism, and when the center column is erected, it can be easily and reliably erected by simply moving the center column to the upright position. The present invention aims to provide a movable center column device.

The structure of the present invention will be explained with reference to an embodiment shown in the drawings. 1 is a shutter case, 2 and 2 are shutter curtains, and 3 is a central pillar, and the central pillar 3 is movable. be. Reference numerals 4 and 4 denote a pair of front and rear hanger rails, and the front and rear pair of hanger rails 4, 4 are provided along the shutter curtain storage opening 5 of the shutter case 1 in front and rear thereof, and are connected to the middle pillar 3. is movably suspended from a pair of front and rear hanger rails 4, 4 by means of hanging wheels 6, 6. That is, reference numerals 7, 7 are suspension plates of the middle pillar 3, and the suspension wheels 6, 6 are attached to the suspension plates 7, 7 by bolts 8, 8. As shown in FIG. 4, the middle pillar 3 is divided into an upper part 12 and a lower part 9 at its upper parting line 3', and the lower part 9 is connected to its upper part 12 through a power hinge 10 and a partner hinge 11. It is connected so that it can pivot 90 degrees in the horizontal direction. The power hinge 10 is configured so that the lower part 9 of the middle pillar 3 is elastically biased in the same direction as the upper part 12, and can be locked in that position when pivoted 90 degrees. It is something.

An angle member 1 is attached to one suspension plate 7 of the middle pillar 3.
The upper latch 13 is attached via the upper latch 3a, and a latch receiver 14 with which the upper latch 13 engages is provided at the upright position of the middle pillar 3, protruding from the micro switch box 14a. Reference numeral 15 denotes a locking/disengaging chain for the upper latch 13. By pulling the locking/disengaging chain 15 downward, the upper latch 13 can be disengaged from the latch receiver 14. 16 is a micro switch, and the micro switch 16 is connected to the latch receiver 1.
4, and detects when the upper latch 13 is engaged with the latch receiver 14.

The micro switch 16 is linked to the shutter's electric opening/closing mechanism (not shown), and is connected to the middle pillar 3.
It may be configured such that the electric opening/closing mechanism does not operate unless the upright installation is confirmed.

In the structure as described above, when the shutter curtains 2, 2 are lowered, the middle pillar 3 is erected at a predetermined position in advance. When the upper latch 13 of the middle pillar 3 is guided by the
is engaged with the latch receiver 14, and at the same time the micro switch 16 is operated to close the upper latch 13 and the latch receiver 14.
The engagement with the center pillar 3 is confirmed, and the middle pillar 3 is fixed in that position. In the case where the micro switch 16 and the electric opening/closing mechanism are interlocked, the shutter curtains 2, 2 cannot be lowered unless the center pillar 3 is confirmed to be erect, so safety is ensured at that time.
On the other hand, when the shutter curtains 2, 2 are opened, the middle pillar 3 is guided by the pair of front and rear hanger rails 4, 4 and moved to the storage position, and the lower part 9 is turned 90 degrees at that position. The middle pillar 3 can be stored neatly along the wall surface or pillar surface.

By the way, since the middle pillar 3, which is erected and stored as described above, is suspended from the pair of front and rear hanger rails 4, 4, the middle pillar 3 is suspended during reciprocating between the standing position and the storage position. It will not accidentally rotate horizontally or sway back and forth. Therefore, when erecting the middle pillar 3, it is only necessary to move it to the erecting position, and there is no need to perform operations such as direction correction, and the middle pillar 3 can be erected easily and reliably. Can be done.

In short, the present invention is a shutter that is movably suspended by rolling a hanger roller attached to the upper part of the middle column on a hanger rail provided along the shutter curtain storage opening of the shutter case. In the movable middle pillar device, a pair of hanger rails are provided in front and back in parallel with the storage opening, and the middle pillar is divided into an upper part and a lower part, which include the front and rear hanging parts. The upper part is used as a rotation fulcrum, and the lower part is pivotable horizontally by 90 degrees.
The center column suspended from a pair of front and rear hanger rails can be moved while always maintaining a predetermined direction.
When opening the shutter curtain, leave the upper part of the middle pillar with the hanging part in the same position, and pivot only the lower part horizontally by 90 degrees to turn the middle pillar, allowing it to touch the wall or the wall. The movable center column device not only can be stored neatly along the column surface, but also has a latch mechanism and its engagement detection mechanism on the top of the center column. This has very useful practical effects, such as being able to easily and reliably set it upright simply by moving it to the upright position.
