[0003] [Patent Document 1] Patent No. 5757016 Summary of the Invention [Problem to be solved by the invention]

[0004] The object of this invention is to provide a center post that can be fixed even if foreign matter accumulates in the filler metal, and a shutter device equipped with this center post. [Means for solving the problem]

[0005] The invention described in claim 1 is a center pillar of a shutter device that has a rod-shaped member that is inserted into a filler metal, and has holes or grooves formed on the outer periphery of the rod-shaped member for scraping out foreign matter that has accumulated in the filler metal.

[0006] The invention described in claim 2 is a center pillar of a shutter device that includes a rod-shaped member that is inserted into the filler metal, and a protrusion is formed on the outer periphery of the rod-shaped member for scraping out foreign matter that has accumulated in the filler metal.

[0007] The invention described in claim 3 is a shutter device equipped with the center pillar described in claim 1 or 2. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a center post that can be fixed even if foreign matter accumulates in the filler metal, and a shutter device equipped with this center post. [Brief explanation of the drawings]

[0009] [Figure 1] 1 is a side view of a center pillar of a shutter device according to an embodiment of the present invention; [Figure 2] 10 is an explanatory diagram showing a cross section of a drop plate provided on the center pillar of the shutter device. FIG. [Figure 3] 10 is an explanatory diagram showing a cross section of a modified example of the drop plate provided on the center post of the shutter device. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0010] Next, the present invention will be described with reference to the accompanying drawings, in which parts not relevant to the description may be omitted.

[0011] As shown in FIG. 1, a shutter device 10 according to an embodiment of the present invention includes a shutter curtain 20, a center post 30, and a metal filler 40. The shutter curtain 20 is made up of multiple slats (not shown) connected in the vertical direction and is provided so that it can be raised and lowered to open and close the opening. Each slat is made of an aluminum alloy or steel plate.

[0012] The center pole 30 is disposed between the two shutter curtains 20 and can guide the raising and lowering of the shutter curtains 20. The center pole 30 is structured so that it can be removed when the shutter curtains 20 are opened.

[0013] The center post 30 has a dropper (an example of a rod-shaped member) 302a on the indoor side. The dropper 302a is a rod-shaped metal fixture that can move up and down in the longitudinal direction of the center post 30.

[0014] The filler metal 40 is a metal member that is embedded in the floor surface and has, for example, a rectangular parallelepiped recess formed therein. The lower end of the drop metal 302a is inserted into this recess, and the center pillar 30 is fixed thereto. In this way, since the filler metal 40 is provided on the floor surface, foreign matter will accumulate in the recess of the filler metal 40 after long-term use of the shutter device 10.

[0015] Next, the drop metal 302a of the center pillar 30 will be described in more detail. A plurality of grooves 304a are formed at the tip of the drop plate 302a at intervals in the longitudinal direction, as shown in Figure 2. Each groove 304a is formed so as to surround the outer periphery of the drop plate 302a. The range in which the multiple grooves 304a are formed is preferably at least the range below the upper surface of the filler metal 40 (the range of the depth of the recess of the filler metal 40 indicated by dimension L) when the drop metal 302a is advanced. Therefore, even if foreign matter accumulates in the recess of the filler metal 40, the foreign matter is scraped out by the action of the groove 304a every time the drop metal 302a is pulled out of the recess.

[0016] Note that the groove 304a may be replaced by a depression (not shown).Furthermore, the dropper 302a may be replaced by a dropper 302b having a protrusion 304b formed thereon for scraping out foreign matter, as shown in FIG.

[0017] Thus, according to the shutter device 10 of this embodiment, a groove 304a is provided at the tip of the drop metal 302a of the center pillar 30, and foreign matter accumulated in the filler metal 40 is scraped out, so that the function of fixing the center pillar 30 is maintained for a long period of time.

[0018] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and all changes in conditions that do not deviate from the gist of the present invention are within the scope of application of the present invention.
