It is assumed that it has a concave groove line shape in a letter shape, and receives the shutter body lower end under the concave groove condition and alternately arranges it between the panels of the shutter body. In the shutter main body side end portion, one side wall upper portion is cut away at the shutter main body side end, and each of the alternately arranged escape hinge frames of the alternate regions arranged alternately at the upper cut portion is sequentially released. In order to prevent the lower frame from protruding above the floor surface, the lower frame is installed by embedding it in the floor surface so as to be flush with the lower frame. The digging space is formed by digging into the floor in a concave shape according to the size of the cutout.

[Problems to be Solved by the Invention] In this case, since the horizontal pull shutter is located at the cutout portion, it can be folded and opened, and the concave groove can be extended and closed, and the lower end of the shutter body can be received in the concave groove. It is possible to shut off the inside and outside by
Therefore, a horizontal pulling shutter with excellent blocking performance can be obtained, but on the other hand, in order to enable the running hinge frame to be retained and released and the hinge frame to be released and released in the upper and lower steps of the concave groove, There is a strong tendency for the depth of the recessed groove to become deep, and because the lower frame is embedded flush with the floor surface, there is the problem that foreign matter and dust easily enter it, and its cleaning is complicated. However, since it is necessary to form a digging space by partially digging the floor surface when installing, not only is the installation work complicated, but the step due to digging may damage the appearance. However, there is a problem that the part is constantly easily dead-spaced.

The present invention has been made in view of the above circumstances, and the problem to be solved by the present invention is to secure the above-mentioned internal and external blocking properties as much as possible, while eliminating these problems and allowing foreign matter and dust to enter. The purpose is to provide a lower frame for a horizontal shutter that prevents it as much as possible and that can be easily cleaned even if it enters.

[Means for solving the problem]

Therefore, in the present invention, the engaging and holding of the upper and lower running hinge frames and the releasing and releasing of the escape hinge frame are performed in the front and rear planes. Therefore, for the former, for the latter of the lower frame substrate longitudinal length, for the latter. By using a pair of parallel raised ridges with the shutter main body side end removed, and the recessed groove between these ridges to receive and fit the lower end of the shutter body, the internal and external cutoff property is reduced as much as possible. Of the shutter, the prevention of foreign matter and dust from entering as much as possible, the ease of cleaning, and the elimination of the dug space. One of the alternate running hinges is provided so that the lower end of the traveling hinge frame is always engaged and held, and the full length ridges are provided along the entire length in the longitudinal direction of the lower frame substrate, and the other of the alternate alternate escapes. Release the lower end of the hinge frame one by one to escape As described above, an end-removing ridge formed by removing the end of the lower frame substrate on the side where the shutter body is suspended is provided in parallel with the full-length ridge, and the lower end of each panel of the shutter body is received and fitted. As described above, the present invention relates to a lower frame of a horizontal pulling shutter, which is characterized by comprising the above-mentioned full-length raised ridges and concave grooved ridges which are concavely arranged between the end-removed raised ridges, which is the gist of the invention. Is the means of.

〔Example〕

The present invention will be described more specifically with reference to the drawings showing the following embodiments. 1 is a horizontal pull shutter, 2 is a shutter body, 3 is a panel of the shutter body 2, and 5a is an alternate between the panels 3 of the shutter body 2. One of the traveling hinge frames arranged on the other side, 5b the other escape hinge frame on the other side, 10 a suspension frame on the shutter body 2 suspension side, 11 a shutter frame on the front side of the shutter body 2 and 20 an upper frame. Frame, 30 is vertical frame, 40 is these upper frame 20, vertical frame
The lower frame is a shutter frame of the horizontal pull shutter 1 together with 30.

The lower frame 40 of the horizontal pulling shutter 1 has the entire length in the longitudinal direction of the lower frame substrate 41 so that the lower ends of the traveling hinge frames 5a, which are alternately arranged between the panels 3 of the shutter body 2, are always engaged and held. The entire length of the ridges 42 that are bulged over the entire length, and the lower end of the lower frame substrate 41 on the side where the shutter main body 2 is suspended so that the lower end of each of the other alternating escape hinge frames 5b alternately arranged is released. An end-removing ridge 43 that is cut away and arranged in parallel with the full-length ridge 42, and the full-length ridge 42 and the end ridge so that the lower ends of the panels 3 of the shutter body 2 are received and fitted. It is provided with a concave groove 47 arranged to be recessed between the raised ridges 43.

In this example, the lower frame substrate 41 is made of stainless steel with its upper surface horizontal and bent in a U-shaped cross section, and the full length raised ridges 42 and the end-removed raised ridges 43 are both hollow square pipe shapes. As a separate product made of stainless steel, the lower frame substrate 41
By being fixed to the horizontal upper surface with a screw 44 from the lower surface side, the lower frame substrate 41 is provided so as to be raised.

At this time, the full-length ridges 42 of this example are arranged on the lower frame substrate 41 so as to divide the inside and the outside, for example, the height of 2 cm or less is set to extend over the entire length of the lower frame substrate 41. The end-removed ridge 43 substantially corresponds to the total dimension of the end of the shutter main body 2 on the hanging side, which is equal to the width of the two panels 3 in the shutter main body 2 and the folding margin width of the shutter main body 2. Along the length, a cut-out portion 45 is formed by this, and the cut-out portion 45 is formed in parallel with the full-length ridge 42 so as to form a positional relationship with the front-rear plane.
It has the following height, and the concave groove 47 of this example
Is a slightly larger depth width between the full length ridges 42 and the edge-removed ridges 43, for example, having a depth of 2 cm or less. It communicates with each other and is open to this.

Further, in the lower frame 40 of this embodiment, the lower end of the traveling hinge frame 5a of the shutter main body 2 is always engaged and held by the synthetic resin slide piece 12 having the downward grooves 14 respectively disposed at the lower ends of the traveling hinge frame 5a. The full length ridges 42 are slidably fitted in the downward grooves 14 of the slide pieces 12 through the above-mentioned slides so as to be slidable in the longitudinal direction. By attaching the shutter main body 2, the above-mentioned usual engagement hold is obtained and maintained. Further, the release escape of the lower end of the escape hinge frame 5b of the shutter main body 2 is performed through the synthetic resin slide pieces 13 similarly having the downward grooves 14 respectively arranged at the lower ends of the escape long frame 5b, and the downward grooves 14 are similarly provided. This is done by fittingly engaging the end-removed raised ridge 43 with the end-removed raised ridge 43 and sliding the end-removed raised ridge 43 in the longitudinal direction. Since it is formed, the slide escape is performed by releasing the engagement at the cutout portion 45 by releasing the engagement.

At this time, the receiving fitting of the recessed groove 47 at the lower end of each panel 3 in the shutter body 2 is about 5 to 6 mm from the upper end in this example, and the lower frame of each panel 3 itself is in the receiving shape. Therefore, by sequentially sliding each panel 3 of the shutter main body 2 into the receiving portion 45, the receiving and fitting are sequentially received and released. Especially, at the time of releasing, the hinge frames 5a and 5b are rotated. Then, the lower frame 40 is folded at right angles.

As a result, the shutter body 2 of the horizontal pulling shutter 1 folds and opens the absent portion 45 like a folding door pocket, opens the shutter frame, and allows the lower frame 40 to enter and exit, and vice versa. The extension of the shutter frame is closed by the operation of.

Since the lower frame 40 is generally embedded and installed so that the horizontal lower frame substrate 41 is flush with the floor surface, when the shutter body 2 is folded and opened, the lower frame 40 is exposed, but the concave groove 47 is formed. Is not so deep, and is located between the full-length raised ridges 42 and the end-removed raised ridges 43, so that foreign matter and dust can be prevented from entering as much as possible, while brushes, brushes, etc. Since the part to be removed can be swept out by the cleaning, the cleaning thereof is easy, and the height of the raised ridges 42 and 43 is not so high, so that it is possible to prevent stumbling to the pedestal as it goes in and out. It is suitable for access to and from the floor. Further, when the shutter main body 2 is extended and closed, the lower end of the panel 3 of the shutter main body 2 is received and fitted in series in the concave groove 47 in which the full length ridge 42 extending over the entire length of the lower frame 40 exists on one of the inner and outer sides. While the inside and outside are blocked to a considerable extent and airtightness is obtained, it is possible to prevent light leakage and the like, and it is possible to secure the blocking property as much as possible.

In the figure, 4 is a vertical frame of the panel 3 that forms the hinge 6 together with the traveling hinge frame 5a and the escape hinge frame 5b, 7 is a handle provided on these hinge frames 5a and 5b, and 8 is each traveling hinge frame 5a. Traveling hinge frame 5a for supporting the shutter main body 2 protruding above on the upper frame 20 and supporting it, 9 is a door roller for traveling, 9 is a deflection stopper wheel installed on the upper end of each escape hinge frame 5b, and 15 and 16 are slide pieces 12, 13. A fixed rivet and a fixing screw, 21 is a housing portion for rolling the door roller 8 in the upper frame 20, 22 is a channel member for rolling contact with the anti-sway wheel 9 in the upper frame 20, and 23 is a side wall cutout of the upper frame 20 over its entire length. After being formed into a shape, the cutout portion 45 is installed leaving the same length as that in the lower frame 40, and the attached side wall is installed and fixed so as to block the remainder, and 46 is an end cutout. The end piece members installed at the tip of the removal side are shown respectively.

Although the illustrated example is as described above, the lower frame should be constructed by integrally molding the lower frame substrate, the full-length ridges and the ridges with no edges at the end for extrusion processing. ，
