Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a fixing device for a central pillar for a shutter, which is installed at a wide entrance/exit of a building and is opened/closed.

[Conventional technology]

Conventionally, in order to fix the middle pillar for a shutter, the middle pillar A is installed vertically between the upper magsa and the floor as shown in Fig. 7, and at this time, it is guided to the guide case B attached to the lower part of the middle pillar A. It is known that the tip of a gate-shaped drop lever C is inserted and fixed into a saucer D provided at the bottom.

[Problem that the invention attempts to solve]

When the drop rod C is dropped into the lower tray D and fixed by the upper magsa part and the drop rod C as in the conventional method of fixing the center column, the shutter receives strong winds during typhoons or gusts, and the shutter receives wind pressure. The middle pillar is pushed, and the middle pillar also bends due to this shutter, and the lower part of the middle pillar is warped and pushed, and the wind pressure of swinging back is repeated, and as a result, the drop rod inserted into the lower saucer comes off from the saucer. , the shutters were thrown into a frenzy due to the wind, and were eventually destroyed in pieces.
It was dangerous and could lead to personal injury.

[Means for solving problems]

In view of such circumstances, the present invention is an idea to eliminate this problem.In a shutter center column that is installed vertically with the upper end on the magsa part and the lower end on the floor, the lower side of the shutter center column is installed vertically. In this case, the case that guides the drop rod is installed vertically with a mounting plate, and this case mounting plate is bent in the horizontal direction at a position that extends downward and slightly protrudes from the bottom of the center column. In the bent overhang piece, an insertion hole for the drop lever is bored opposite to the drop lever, and furthermore, a cover plate is provided in the lower floor part facing the drop lever, and the same insertion hole as the insertion hole is bored in the upper part. A shutter characterized in that a slideable saucer is provided, and the projecting piece is positioned below the cover plate, so that the drop rod can be inserted into and removed from the insertion hole of the cover plate and the insertion hole of the projecting piece. The present invention provides a middle pillar fixing device for use.

〔Example〕

Next, an embodiment of the shutter center column fixing device according to the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a middle pillar used for the shutter, and this middle pillar 1 is installed vertically between the magsa part and the floor surface, and a case on the lower side of the middle pillar guides a drop rod 2 whose central part is bent into a gate shape. 3 is installed vertically. Further, the mounting plate 4 of the case 3 extends downward, and this extending piece 4a is a stepped part that engages with a positioning protrusion 6 of a saucer 5, which will be described later, provided on the floor W at the bottom of the drop lever 2. A stop portion 4b and an overhang piece 4c that is bent and overhangs laterally at a position slightly projecting downward from the lower end of the middle pillar 1 are integrally provided.

A horizontally elongated insertion hole 7 into which the tip end of the drop rod 2 is inserted is bored in the lower part of the overhang piece 4c opposite to the drop rod 2.

The saucer 5 is box-shaped and has an opening 8 in a part of its upper surface, and a positioning protrusion 6 for the center column 1 is provided on the edge of the opening 8. Further, guide grooves 9 are provided on both sides of the opening 8, and a sliding cover plate 10 is fitted into the guide grooves 9 so that the opening 8 can be opened.

A horizontally long insertion hole 11 is bored in the cover plate 10 at a position corresponding to the drop lever 2 in the closed position, and when the drop lever 2 is pushed down, the case 3 is inserted through the insertion hole 11 drilled in the cover plate 10, It is inserted into a horizontally long insertion hole 7 made in the overhanging piece 4c from the mounting plate 4.

Further, the saucer 5 is provided with the above-mentioned protrusion 6, and the middle pillar 1
It is designed to determine the position of the

[Effect]

The present invention has the above-mentioned configuration, and a saucer 5 is provided on the floor W, and a cover plate 10 of the opening 8 at the top of the saucer 5 is provided.
When the middle pillar 1 is positioned by sliding the opening 8 and fitting the protrusion 6 provided on the saucer 5 between the lower end of the middle pillar 1 and the locking part 4b, the extension piece 4a integrated with the case 3 The overhanging piece 4c comes to be located inside the saucer 5. After the center column 1 is positioned in this way, the cover plate 10 of the opening 8 is closed until it hits the extension piece 4a, and the drop lever 2 guided by the case 3 is pushed down along the case 3, and the drop lever is closed. The lower end of 2 is inserted through the insertion hole 11 formed in the cover plate 10 and into the insertion hole 7 formed in the inner projecting piece 4c, and is locked therein.
Therefore, the drop lever 2 is locked by the cover plate 10 and the overhanging piece 4c, and even if wind pressure is applied, the drop lever 2 will not float up on the cover plate 10 and come off.

Moreover, when removing the center pillar 1, the above described operation may be performed in reverse.

〔effect〕

In the present invention, as described above, a case for guiding the drop rod is attached to the lower side of the middle pillar, and this case is integrally provided with a projecting piece bent laterally with a hole for inserting the drop rod in the lower part. This center column fixing device for shutters consists of a saucer with a slideable cover plate with an insertion hole in the upper part on the lower floor facing the drop rod, so that it can be used even in strong winds. However, the center pillar is firmly fixed by pushing down the drop rod into the insertion hole cut into the cover plate of the saucer and the insertion hole drilled in the overhanging piece, so even if it is subjected to wind pressure, the drop rod will not hold the cover. There is no risk of it floating up on the board and coming off, which helps prevent accidents.
