Description

[Detailed description of the invention] This invention is a central pillar mounting device for a central pillar that is installed in the middle of a shutter when the shutter curtain is lowered in a shutter in which two or more shutter curtains are installed in the frontage of a building. This is related to.

For shutters with two or more shutter curtains installed at the frontage of a building such as an entrance/exit, a central pillar is erected in the middle when the shutter curtain is lowered, and when the shutter curtain is raised, It is known that the middle pillar is to be removed, and an insertion fitting having an upper end insertion part into which the upper end of the middle pillar is inserted from below is used in the upper part of the opening where the middle pillar is to be erected. .

However, in order to facilitate the insertion of the middle pillar, this upper end insertion part has conventionally been formed larger than the external dimensions of the middle pillar in a part of the opening for raising and lowering the shutter curtain on the bottom of the shutter case. As a result, the erected center pillar moves irregularly, creating a step due to positional shift at the connection between the shutter case and the guide member of the shutter curtain between the shutter case and the middle pillar.
This has caused problems such as preventing the shutter curtain from rising and lowering and causing damage. In addition, when the upper end insertion part of the middle pillar is an opening recessed part that matches the outer shape of the upper end of the middle pillar, when inserting the middle pillar, the corner of the middle pillar will hit the opening edge of the upper end insertion part, and the middle pillar will Not only is it time-consuming to insert, but the upper end of the center pillar may be damaged.

The present invention aims to solve the problems in view of the above-mentioned conventional situation, and is aimed at improving the shutter case of a shutter in which two or more shutter curtains are installed in the frontage of a building. An insertion fitting at the upper end of the middle pillar is provided in the opening for raising and lowering the shutter curtain on the lower surface, and the insertion fitting is folded into a pair of vertical guide plates for guiding the shutter curtain and the lower end of the guide plate. In the case of a horizontal mounting seat that is bent and extends to both sides of the opening, by widening the bending part between the guide plate of the insertion fitting and the mounting seat outward, the outer dimensions of the upper end of the center column can be The large upper end insertion part of the middle pillar is recessed in its lower surface, and the four corners of this upper end insertion part are provided with slopes that protrude inward from the vertical side walls of the upper end insertion part. The downwardly expanding slope of the projection is used as a guide slope for inserting the center column, and the slope connected to the slope and obliquely intersecting the vertical side wall fixes the upper end of the center column. Since the lower surface of the upper end insertion part is formed to be larger than the size of the center column, when the center column is set up, the upper end is guided by the guide slope, making it easy and reliable. In addition, the support surface formed adjacent to the guide slope supports the middle pillar inserted into the upper end insertion part in an immovable state, eliminating the difference in level between it and the guide of the shutter curtain. An object of the present invention is to provide a center pillar mounting device for a shutter, which can smoothly raise and lower the shutter curtain without causing problems, and can prevent damage to the upper ends of the shutter curtain and the center pillar.

To explain the structure of the present invention with reference to an embodiment shown in the drawings, in Fig. 1, 1, 1 is a shutter curtain installed at the frontage of a building, 2, 2 is a left and right guide rail, and 3 is a central pillar. , 4 is a shutter case, and 4a is an opening through which the shutter curtain is raised and lowered. As is well known, the middle pillar 3 has a horizontal cross section roughly in the shape of a square, and includes a guide rail formed by the front and rear side walls and an intermediate partition, so that it can be used when lowering the shutter curtains 1, 1. The shutter curtains 1, 1 are installed upright and removed after the shutter curtains 1, 1 are raised, and the mounting structure of the present invention has the configuration shown in FIGS. 2 to 4.

That is, 7 is an insertion fitting for inserting the upper end of the middle pillar 3, and as is well known, it has an expanded part for guiding the shutter curtains 1, 1 to the guide rail of the middle pillar 3. A pair of guide plates 7a and a mounting seat 7b connected to the lower end of the guide plate 7a and bent horizontally to form flanges on both sides of the opening 4a are bent in series, and these are connected to the intermediate connecting member 7.
It is assembled and formed by c.

In the present invention, the upper end insertion part 5 is formed on the lower surface of the insertion fitting 7 so that the upper end of the middle pillar 3 can be easily inserted. The upper end insertion part 5 is provided with two cut grooves 7d near the outer end of the bent part between the guide plate 7a and the mounting seat 7b, and is wider than the upper end external dimension of the middle pillar 3 in the width direction and the length direction. The center portion, which is slightly larger, is expanded outward to form a vertical side wall 7e and a horizontal upper base 7f.

In the present invention, a portion of the bent side wall 7e of the upper end insertion portion 5 is further processed to provide a protrusion 6. The protrusion 6 is formed by extruding a sloped surface and symmetrically protrudes inwardly from the vertical side wall 7e of the upper end insertion portion 5, and has a substantially pyramidal shape. The downwardly expanding slope of the pyramid serves as a guide slope 6a for inserting the middle pillar 3, and is connected to the upper part of the slope, and the slope diagonally intersecting the side wall 7e is a support for fixing the upper end of the middle pillar 3. It is formed as a surface 6b. Therefore, the middle pillar 3 is guided by the guide slope 6a into the upper end insertion part 5, and its upper end corner is immovably supported by the support surface 6b, and the middle pillar 3 is shown in FIG. As shown, it is erected at the correct position both in the front-back direction and in the left-right direction of the opening 4a. In addition, 7g is a part where a gentle guide slope is similarly formed before and after the upright part of the guide plate 7a of the insertion fitting 7, and this part also allows the shutter curtain 1 to be smoothly inserted into the guide rail of the middle pillar 3. I will guide you to.

Note that the lower end side of the middle pillar 3 is fixed to the floor surface with a drop lever or the like.

In the structure configured as described above, when lowering the shutter curtains 1, 1, the middle pillar 3 is set upright. By inserting it into the recessed part 5 from below and fixing its lower end to the floor surface, the middle pillar 3 is erected vertically and immovably. Therefore, when the shutter curtains 1, 1 are pulled down, the shutter curtains 1, 1 can be guided by the guide rails 2, 2 and the middle pillar 3 and lowered. Also, shutter curtains 1, 1
To remove the middle pillar 3, remove the lock at its lower end, and then pull the upper end diagonally downward from the upper end insertion part 5. The middle pillar 3 will come off, so carry it to an appropriate location. You can store it in.

By the way, when installing the middle pillar 3 upright as described above, when inserting its upper end into the upper end insertion part 5 from below, the corners of the middle pillar 3 should be aligned with the insertion guide slopes 6a of the projections 6 at the four corners. As you are guided upwards, move to center pillar 3.
can be inserted smoothly and reliably. Since the upper end of the inserted middle pillar 3 is closely supported by the support surface 6b of the protrusion 6, the middle pillar 3 is erected in an immovable state, and there is no step between it and the guide plate 7a. . Therefore, the shutter curtains 1, 1 can be raised smoothly and damage to them can be prevented. Furthermore, since the middle pillar 3 can be inserted smoothly as described above, damage to the upper end of the middle pillar 3 can be prevented, and the service life of the middle pillar 3 can be greatly extended. .

In short, the present invention provides a system for shutters that have two or more shutter curtains installed at the frontage of a building.
An insertion fitting is provided at the upper end of the middle pillar in the opening for raising and lowering the shutter curtain on the bottom surface of the shutter case, and the insertion fitting is connected to a pair of vertical guide plates that guide the shutter curtain, and the lower end of the guide plate. and a horizontal mounting seat that extends to both sides of the opening.By widening the bending part between the guide plate of the insertion bracket and the mounting seat outward, the middle pillar can be The upper end insertion part of the middle column, which is larger than the outer dimensions of the upper end, is recessed in its lower surface, and the four corners of this upper end insertion part are made to protrude inward from the vertical side walls of the upper end insertion part. A protrusion is formed by a sloped surface, and the downwardly expanding slope of the protrusion is used as a guide slope for inserting the middle pillar, and is connected to the slope,
Since the slope diagonally intersecting the vertical side wall is formed as a support surface for fixing the upper end of the center column, even though the lower surface of the upper end insertion part is formed larger than the size of the center column, the center column cannot be erected. When installing the curtain, the upper end can be guided by the guide slope for secure and easy insertion.Furthermore, the inserted center column can be supported immovably and there is no difference in level between it and the guide of the shutter curtain. This has an extremely useful practical effect of making it possible to smoothly raise and lower the shutter curtain without causing any problems, and to prevent damage to the upper ends of the shutter curtain and the middle pillar.
