Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a center pillar of a building shutter.

[Background Art] In a building shutter provided at a building entrance with a wide opening, the entrance is opened and closed by a plurality of shutter curtains, and a joint of the shutter curtain is guided by a removable center pillar. .

Conventionally, a common center pillar is manufactured by bending a steel plate or combining it.For a large shutter that requires strength, an auxiliary member with a U-shaped cross section over the entire length of the center pillar is used. In addition, a combination was installed.

[Problem to be Solved by the Invention] The conventional center pillar described above is based on functions and has not been given much design consideration. For this reason, it has not sufficiently responded to the demands of customers who place importance on designs such as shops.

In view of such circumstances, the present invention aims to provide a center pillar having a high design value without impairing the function and strength as the center pillar.

Means for Solving the Problems According to the present invention, a pair of shutter curtain guide grooves are formed on the left and right, and one opening groove of one of the guide grooves and another guide groove located symmetrically with the opening edge. The opening edge of the groove is connected to a cylinder, a substantially half-split cylindrical outer plate having a shape obtained by dividing a cylindrical body such as a polygonal tube along the axis, and the both guide grooves on the side opposite to the outer plate. A main pillar in which a side fitting groove is formed on the opening edge and a central fitting groove extending in the longitudinal direction between the two guide grooves on the side opposite to the outer plate portion, and a lacking portion of the outer plate portion. In addition to the outer plate portion, a cylindrical body such as a cylinder and a polygonal cylinder is substantially completed together with an outer plate portion, and a central portion has a reinforcing cover formed with a rib extending in a longitudinal direction, and both side edges of the reinforcing cover are on the side. The center pillar main body is formed by fitting in the fitting groove, and the tip of the rib is fitted in the center fitting groove. It is.

[Operation] For the accessories required for the center pillar, the reinforcing cover is removed and attached to the main pillar, and after attaching the accessory, the reinforcing cover is fitted to the main pillar. The middle pillar body composed of the main pillar and the reinforcing cover has a hollow cylindrical shape, and is lightweight and has high strength.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

The main body 1 is a main pillar 2 which is a pultruded product such as an aluminum material.
And the reinforcing cover 3. In addition, as shown in the cross section of FIG. 1, the center column main body 1 has a substantially circular cross section.

 The main column 2 will be described.

Guide grooves 5, 5 into which the ends of the shutter curtain 4 are fitted are formed symmetrically, and the bottoms of the guide grooves 5, 5 are connected by a connecting portion 6. A closed section is formed by the bottoms of the guide grooves 5, 5 and the connecting portion 6.

Inside the opening edge of the guide groove 5, a seal groove 7 for fitting a seal material (not shown) such as dust and rainwater is formed.

Opening edges on one side of the guide grooves 5, 5 are connected by the half-cylindrical outer plate portion 8 obtained by dividing a cylinder along an axis, thereby forming a substantially half-moon-shaped closed cross section. The center of the guide groove 5 is eccentric in the direction away from the outer plate 8 with respect to the center of the curved surface of the outer plate 8. Further, both side edges of the side wall portion 9 on the side opposite to the outer plate portion of the guide groove 5 project, and a center fitting groove 10 is formed by the center side edge portion and the connecting portion 6. A side fitting groove 11 that opens laterally is formed between the portion and the outside of the opening edge of the guide groove 5.

 Next, the reinforcing cover 3 will be described.

A cover portion 12 having an arc-shaped cross section that forms a circle with the outer plate portion 8.
Rib 13 extending toward the center of the curved surface is formed at the center of
At the tip of the rib 13, a flange portion 14 that fits into the central fitting groove 10 is formed.

Further, a pair of tongue pieces 15 and 16 that can be fitted in the side fitting grooves 11 are formed on both side edges of the cover portion 12.

A latch receiving plate 17 having an L-shaped cross section is provided inside the two guide grooves 5, 5 at a required height.

On one surface of the latch receiving plate 17, a plurality of engaging holes 18 are formed at a required pitch as shown in FIG. The surface of the latch receiving plate 17 on which the engaging hole 18 is formed is positioned on the bottom surface of the guide groove 5, and the other surface is fixed to the side wall portion 9 by a required means such as a rivet.

As shown in FIG. 5, a latch bar 19 provided in the shutter receiving plate 17 so as to be able to enter and exit in the width direction is disengaged from the latch receiving plate 17.

As shown in FIGS. 3 and 4, the reinforcing cover 3 has a cut-off lower end, and the cut-off portion has a central pillar main body 1.
A fixing tool 20 for fixing the lower end of the base to the floor is attached.

The fixture 20 includes a U-shaped pin 21 that fits into and disengages from a hole (not shown) in the floor, and a box 22 that slidably supports the pin 21. It is fixed to the side wall 9 of the main body 2.

Hereinafter, the procedure of assembling the center pillar, and attaching and removing the center pillar will be described.

The latch receiving plate 17 is fixed without the reinforcing cover 3 attached. Next, the flange portion 14 of the reinforcing cover 3
Into the central fitting groove 10 and the two pairs of tongue pieces 15 and 16 on both sides into the side fitting grooves 11, respectively, and slide the reinforcing cover 3 in the axial direction, so that the main pillar 2 and the auxiliary cover 3 Are integrated.

After assembling the main column 2 and the reinforcing cover 3,
Is fixed to the main column 2 to complete the assembly of the center column.

To attach the middle pillar, insert the upper end into the shutter body side, make it vertical, and then fit the pin 21 into the hole in the floor. In addition, the removal of the center pillar may be performed in the reverse order of the installation.

Further, since the center of the shutter curtain is displaced from the center of the center post when the center post is attached, the restriction on fitting is reduced.

In the above embodiment, the shape formed by the outer plate portion 8 and the cover portion 12 is circular. However, it is needless to say that the shape may be a polygon having four or more squares.

[Effects of the Invention] As described above, according to the present invention, the following excellent effects are exhibited.

(I) Since the external appearance has a shape of a column, etc. and is also made of a drawn material, the appearance is excellent.

(Ii) Since the cross-sectional shape is a substantially hollow cylindrical shape, it is lightweight and has high strength.

(Iii) The center pillar main body has a two-part structure. In particular, the reinforcing cover covers screws, rivets and the like for fixing the latch receiving plate and the like, functions as a decorative cover, and improves the design of the center pillar.

(Iv) Since the reinforcing cover has a rib at the center, the reinforcing effect is high, and the mounting of the reinforcing cover to the main pillar can be performed only by fitting both ends and the tip of the rib into the fitting groove formed in the main pillar. Workability is good because no fastening means such as rivets and screws are used.
