Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a central pillar device for a shutter that uses a hanger rail in a shutter with a wide frontage.

[Conventional technology]

Generally, the upper part of the central pillar used in a shutter was fitted into the lintel, and the lower part was fixed to the floor with a drop rod. In addition, when using a guide rail, as shown in Figs. 4 and 5, a rail a is arranged in a straight line along the lintel, and rollers b and b that roll on this rail a are supported pivotably. hanging rod c
When the center column d is suspended and stored on the wall e, the center column d can be rotated by 90 degrees, and the guide section f is extended under the lintel at the set position of the center column. The middle pillar d, which has moved along the rail a, is held between the guide parts f so as not to rotate, and the middle pillar d is then moved along the rail a.
It is also known that the lower part of the barrel is locked with a drop rod.

[Problem that the invention attempts to solve]

In the former known method, the center column is carried and fitted each time. Therefore, it is troublesome to attach or remove the inner column, and it is difficult to carry the inner column because it is heavy.

In addition, the latter has the disadvantage that the guide portion is provided in a protruding manner at the bottom of the lintel, resulting in an unsightly appearance.

[Means for solving problems]

The present invention was created in order to eliminate these problems in view of the above-mentioned circumstances. It has a guide box for guiding the drop lever, and has a middle pillar for shutter at its lower end, which is provided with an extension member that is connected to the drop lever and slidably fitted thereinto so as to be retractable. In this position, the upper end of the middle pillar can be rotated down from the ceiling level, and in the set position of the middle pillar, a hanger rail with a straight part and a tapered part is installed at the shutter intake so that the upper end of the middle pillar cannot rotate. are arranged along the lintel, using rails for easy transportation, omitting the guide part of the middle pillar, and providing an extension member that can be retracted from the lower end of the middle pillar, spoiling the appearance. The purpose is to ensure that there are no

〔Example〕

Next, an embodiment of a shutter center column device using a hanger rail according to the present invention will be described in detail with reference to the accompanying drawings.

Reference numeral 1 denotes a lintel provided at the upper end of the opening, through which the shutter is raised and lowered. When the opening is wide, a middle post 2 is used, and the middle post 2 is fixed at the central set position, with its upper end positioned at the shutter intake opening of the lintel 1 and its lower part positioned on the floor. Moreover, the middle pillar 2 is a hanging rod 5 which is suspended by a hanger rail 4 arranged inside a case 3 provided at the back along the lintel part 1.
The upper part is attached via an L-shaped metal fitting 6.

The hanger rail 4 is in a straight line at the storage position of the middle pillar on the wall, and the upper end of the middle pillar 2 descends from the shutter inlet of the lintel 1, and can rotate 90 degrees under the ceiling 7. At the set position of the pillar 2, a tapered part 8 is provided to raise the upper part of the middle pillar 2 so that it fits into the shutter intake opening of the lintel part 1.

The suspension rod 5, which suspends the upper part of the center column 2 via an L-shaped metal fitting 6, has rollers 9, 9 that roll along the hanger rail 4 pivotally supported on the upper part, and has a screw on the lower part. A screw is installed to adjust the vertical position of the middle pillar 2.

The control center column 2 is provided with a distraction member 2a slidably fitted to the chain 2 on the lower side, and this distraction member 2a cooperates by fitting a connecting piece 2b into a guide groove 10 provided from the bottom in the overlapped portion of the center column 2. It is designed to move. Further, a guide box 12 for the drop rod 11 bent in a shape is attached to the lower part of the middle pillar 2, and a connecting member 13 attached to the extension member 2a is attached to the lower side of the drop rod 11.
The distal end of the distraction member 2a extends from the lower end of the distraction member 2a. It is made to slide and appear.

In addition, 14 in the figure is a stopper.

[action, effect]

The present invention has the above-mentioned configuration, and the middle pillar 2 whose upper side is suspended along the hanger rail 4 via the suspension rod is
To move the middle post 2 toward the wall after opening the shutter, pull up the drop rod 11 to remove it from the locking tray 15, push the extension member 2a into the middle post 2, and then move it along the hanger rail 4. Move to the storage position. In this storage position, the upper end of the middle pillar 2 is located at the bottom of the ceiling and can be rotated. When rotated 90 degrees, the middle pillar 2 becomes parallel to the wall and can be stored and opened. The section can be used widely.

Also, when closing the shutter, the middle pillar 2, which is stored against the wall, is pulled out from the storage position, and
When the middle pillar 2 is rotated 90 degrees and then moved toward the center along the hanger rail 4, the hanger rail 4 moves from the straight part to the tapered part 8, and while passing through the tapered part 8, the upper end of the middle pillar 2 It moves sequentially while fitting into the shutter intake opening of the lintel part 1, and when the hanging rod 5 hits the stopper 14 provided at the set position of the middle pillar 2, the middle pillar 2 becomes the set position, and the lower part of the middle pillar 2 is moved. The extension member 2a slidably fitted into the middle pillar 2 is pushed out downward through the drop rod 11 provided on the center column 2, and the tip of the drop rod 11 extending from the lower edge of the distraction member 2a is connected to the stopper provided on the floor. It fits into the catch plate 15 and is locked.

As described above, in the present invention, the middle pillar for the shutter, which moves along the lintel while being suspended from the suspension rod, has a guide box on the lower side for guiding the drop rod, and furthermore, the lower end part has a guide box for guiding the drop rod. An extension member that is connected to and cooperates with the drop rod is provided by sliding, and when the middle pillar is in the storage position on the wall side, the upper end can be lowered from the ceiling and rotated, and when the middle pillar is in the set position, the upper end of the middle pillar can be rotated. A hanger rail having a straight and tapered part that fits into the shutter intake opening of the lintel part and prevents rotation is arranged along the lintel part, and the center column and the extension member are extended along the hanger rail. Since the center column can be stored or set by being moved and retracted, the center column can be easily transported using rails, and the guide section that conventionally protrudes downward from the lintel section is no longer required. Even if the central pillar has the above-mentioned distraction member, there is an effect that the appearance does not deteriorate.
