Description

Detailed Description of the Invention 3. Detailed Description of the Invention (Field of Industrial Application) The present invention relates in particular to a vertical folding shutter installed at the opening of a building such as a store.

(Background Art) In recent years, so-called pipe shutters have been widely used in shops and the like due to their good design and transparency when the shutters are closed. However, the shutters, including the pipe shutters, that partition the upper and lower spaces are configured such that one end is fixed to a winding drum installed above, and the shutters are sequentially rolled up by rotation of the drum. Therefore, the winding width becomes extremely large, and the shutter box that houses and fixes the winding drum becomes abnormally bulky, and this bulky shutter box is sometimes installed protruding inside or outside the pipe shutter installation location. This could have been avoided, but it remained a problem.

And, although pipe shutters are superior in terms of design, their designs are uniform.

Although it is especially suitable for unifying the appearance of a neighborhood, its structure does not allow it to meet the demands for diversification of design.

(Purpose of the Invention) The present invention provides a structure that allows the pipe shutter to be seen through from the outside by using horizontal bars at predetermined intervals, as well as the uniformity of the design of the pipe shutter, and the use of the lint-removal drum/Yano Turbonox. To provide a vertically folding shutter which eliminates the drawbacks, allows for various designs, and reduces the storage space when storing a yanotar.

(Structure of the Invention) In accordance with the above object, the present invention forms a vertically folding shutter body on a vertical plane by connecting each horizontal bar with a link that also serves as a partition of an arbitrary shape, and has a predetermined shape on the upper and lower end bars. The structure of the present invention is such that the shutter can be folded and stored only by the left and right guide rails extending over the shutter opening frame. A vertically foldable shutter body is formed by combining the shutters with partition links of arbitrary shapes that can be stored in the horizontal rails, and the shutter body is installed by being guided up and down between the left and right vertical guide rails, The left and right guide rails are extended above the shutter opening frame to a length that is approximately equal to or longer than the folded width of the shutter body, and a retractable hanging wire or chain is housed within these left and right vertical guide rails. It is fixed to the left and right ends of the lower end crosspiece, and each horizontal crosspiece is sequentially stacked and folded as a reference for the lower end crosspiece by winding a hanging wire or chain, and the upper and lower end crosspieces are attached to the upper end, lower end, or The gist of this is a vertically folding shutter that is characterized by a receiving restriction in the vicinity.

In the figure, 15 indicates a ceiling material, and 16 indicates a concrete-finished floor.

The licks 9 in the shutter main body 2 that can be folded in this way are themselves connected to the shutter main body 2.
Also serves as a partition. When using this link (or it may be used as a link device), in addition to the R-shaped link, if the shutter body can be vertically folded, such as by connecting one horizontal bar link, it is possible to use a design element. As such, it is desirable to position this link so that the overall design of the main body is improved. Of course, at this time, depending on the vertical folding link connection, the middle crosspiece can be installed or omitted, and the horizontal crosspiece itself can also be curved, for example, in a wavy manner as a design element.

Also, a hanging chain can be used instead of the hanging wire, and the hanging wire and the hanging chain can be used.

If it is fixed to the bottom crosspiece, in addition to winding at the top, it can also be wound at the bottom, making it possible to reciprocate between the upper and lower rotating shafts, making the lifting and lowering of the bottom crosspiece and horizontal crossbeam more stable. It is.

Further, the left and right vertical guide rails 3.3 may be integrally formed up to above the shutter shield, or may be connected with an extension member near the shutter shield.

On the other hand, the receiving regulation of the lower end beam may not be done directly on the /Yanotar shield, but may be done by protruding pieces protruding from the vertical guide rail in the opposite direction near the upper and lower parts thereof. This can be done arbitrarily when it is necessary to adjust the appearance of the shutter to fit in with the ceiling or the closed height of the shutter body.

Although the present embodiment has been constructed as described above, the present invention can be implemented in various ways as long as it does not go against the gist of the invention, and the specific structure of each component is not limited to the above.

(Effect of the invention) The present invention shunts the left and right vertical guide rails.

The vertical guide rail extends above the shutter shield so that the vertically foldable /yanota body is guided up and down, and at this time, the links can be housed within each horizontal bar of the shutter body, so / The folding width of the Yanota unit can be made extremely small, and the Nyanota unit can be stored vertically in the narrow attic space above the Nyanota shield, while the shutter horizontal beam does not need to be rolled up. It is no longer necessary to do this, and the fit and appearance of the building opening can be greatly improved. In addition, since the shutter main body uses a link that also serves as a partition in an arbitrary shape, the design of the shutter main body can be diversified into various types depending on the link shape and link installation state, improving the uniformity of the design of the pipe shaft. , can retain its transparency benefits.

On the other hand, since the upper and lower end beams are received and regulated by the shutter shield or its vicinity, the structure of the Nyatta body is simplified, and
When closed, the upper end crosspiece supports the hanging load of the shutter body, so the load on the upper end crosspiece can be distributed to the vertical guide rail or building structural materials. Further, the lower end crosspiece can be easily stored near the ceiling when the shutter body is opened.

Furthermore, since the shutter body is lifted and lowered by winding a hanging wire or chain, and this hanging wire or chain is fixed to the lower end crosspiece, the structure can be simplified and trouble-free lifting operation can be achieved over a long period of time. .

As described above, the present invention can secure the advantages of the conventional pipe yanter, eliminate its disadvantages, widen the variety of designs, and achieve stable shutter function without failure.
