Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is an improvement of the sleeve-missing roll shutter, and more specifically, the narrow-width armor part of the sleeve-missing roll shutter is smoothly and reliably attached to the lower guide rail without derailing. The present invention relates to a sleeveless roll shutter equipped with a narrow armor door guide mechanism that can enter and close an opening of a building, and is particularly suitable for use as a mechanism of an electric shutter.

[Conventional technology and technical problems to be solved]

Conventionally, when opening and closing the entrances and exits of factories and large stores with roll shutters, there are places where the crane traveling beam is installed for the entrance and exit of employees after business hours, or in factories equipped with traveling cranes. To avoid it and block it,
Arrange a sleeveless roll shutter that has a narrow armored door with the lower part narrowed by removing the sleeve part, and attach "diving door", "sleeve door", "beam", etc. to the missing sleeve part. There is (jijin book building "building materials, construction method handbook" tenth
Page 85: See Figure 19.6.6 and lines 5-6).

However, in such a conventional sleeveless roll shutter, it is possible to manufacture the narrow shutter door so that it can be accurately guided by guiding it to the guide rails discontinuously arranged below. It is extremely difficult, and I have not heard about the practical example of the sleeveless roll shutter of the type that both sleeves are cut off, I have not heard it yet, at best, cut out only one sleeve, and the guide rail on one side is continued to the lower end, We only know what should be called a "semi-sleeveless roll shutter" of the type in which the swing of the lower end of the narrow width door is controlled.

The present invention has been made in view of the fact that the conventional sleeve-missing roll shutter is insufficient in function as described above, and not only the one-sleeve-cutting type but also the two-sleeve-cutting type sleeve-missing rolls. It is a technical object to provide an effective narrow-width shutter door guide mechanism that can positively and smoothly open and close the shutter.

[Means adopted for solving the problem]

Means adopted by the present inventor to solve the above technical problems will be described below with reference to the accompanying drawings.

That is, the present invention comprises a winding shaft 1 horizontally rotatably mounted in a shutter box 11 attached along a lintel () of a building opening; the winding shaft 1 can be wound and unwound freely. A sleeveless roll shutter 2 which is a connecting member for the installed slats S, S, and is provided with a narrow width sliding door portion 22 in which at least one sleeve portion of the full width sliding door portion 21 is notched and a lower portion is narrowed.
And upper guide rails 4 and 4 which are disposed on the side pillars P and P on both sides of the opening and which regulate the both side edges of the full-width armor door portion 21 above the sleeveless roller shutter 2 in a slidable state. A bottom bar 3 whose lower surface has a contour capable of abutting along the floor below the lintel and which is connected to the lowermost slat S ′ of the narrow armor door 22; , A frame-shaped bar member that is loosely fitted so as to be movable up and down, both ends of which are linked to the upper guide rails 4, 4 in a slidable manner, and the member itself is the sleeveless roll. When the shutter 2 is wound up and the bottom bar 3 is lifted, the guide bar 5 is engaged with the bottom bar 3 and can be lifted together with the bottom bar 3. The guide bar 4 protrudes from the vicinity of the lower ends of the guide rails 4, 4 toward the inside of the opening. Sleeves 6 and 6; Introductory part that opens at the upper edge of this sleeve Entry members 8.8 projecting from the lower surface of the guide bar 5 so as to be able to enter facing the introduction member, and the narrow width armor part 22 along the inside of the sleeve part 6. By adopting the guide mechanism means having as its basic elements the lower guide rails 9 and 9 standing upright on the lower side edges of both sides, the technical bottleneck of the conventional sleeveless roll shutter is broken, and the above technical problems are satisfied. We have realized a product that is sufficient to do so.
