インドに関する。DETAILED DESCRIPTION OF THE INVENTION In this invention, a light-shielding sheet interposed between two flexible transparent sheets is welded and then peeled off along perforations, and a tiltable light-shielding slat is integrated with each transparent sheet. Concerning blinds that are connected to each other.

いた。Conventionally, blinds, which have been commonly used as a light-blocking device and are hung on daylight windows, are made by connecting a number of printing plates (colored slats) with strings, and adjusting the inclination angle of the printing plates at any time according to the angle of entry of the light. Due to the complicated string mechanism that tilts a large number of printing plates at the same time, problems can occur due to the strings becoming stuck or breaking, and the strings are connected manually during the manufacturing process, making them unsuitable for mass production and costly. However, it has become extremely expensive, making it difficult to use it only in specific areas (commercial facilities, interiors of high-end homes, etc.).

る不備を伴っていた。In addition, a pair of film sheets with transparent parts and light-blocking parts arranged in horizontal stripes can be attached to a winding shaft installed horizontally on the upper rail, and one flexible film sheet can be moved up and down to let in and block light. There is a prior art technique described in Japanese Utility Model Publication No. 48-944062 that attempts to do this, but it requires the trouble of attaching a band-shaped light-shielding part with a foil material to the opposing film sheets, and a separate guide mechanism for sliding the film sheets. The complicated mechanism, such as the installation of a window around the satsushi side, was accompanied by deficiencies that not only spoiled the scenery around the window but also increased costs.

Top, seat width (S) ffi 1 meter or less, generally 3
It consists of a soft transparent vinyl chloride resin film standardized to about 4 different dimensions, and another flexible colored light-shielding sheet 3 is interposed between the transparent sheets 1 and 2 to form a polymerized sheet. , the various parts of each sheet are joined and integrated using high-frequency processing. Specifically, the pre-colored light-shielding sheet 3 is a flexible film sheet that is thinner than the transparent sheet ll 2, and cut holes 5 are arranged in parallel at a predetermined interval A necessary to ensure the blade width. . . 5 is bored, and a release material B is applied in advance to the upper surface 9 and lower back surface 10 in the vicinity of the cut-out hole 5, and between the transparent sheets 1 and 2. A polymer (a laminate of film sheets) consisting of three layers is composed by interposing the three layers.

の当接する部分が帯状に溶着８されることになる。Next, the polymer film sheet in such a state is cut into adjacent bands 6 and 7 by, for example, a high-frequency sewing machine (also called a high-frequency welder), avoiding the cut-out hole 5 on the light-shielding sheet 3 side that can be easily seen from the outside. If these are bonded using a bifurcated pressing mold P having a recess in the center as shown in FIG. The transparent sheet 2 in contact with the upper surface 9 is blocked by the mold release material BK and is not welded, and the adjacent band 6 corresponding to the back surface of the upper surface 9 and the contacting portion of the transparent sheet 1 are welded in a band shape 8. will be done.

）。At the same time, the transparent sheet 1 that comes into contact with the lower back surface 1° near the cut-out hole 5 is blocked by the mold release material B and is not welded, and the transparent sheet 1 that comes into contact with the lower back surface 1° near the cut-out hole 5 is not welded to the neighboring band 7 corresponding to the opposite side of the lower back surface 10. Since the abutting part on the transparent sheet 2 side is welded 8 in a band shape,
Generally, above each cutout hole 5, the transparent sheet 1 is
In the lower part, the transparent sheet 2 is welded to the adjacent bands 6.degree. 7 on the front and back sides of the cut-out hole 5, respectively (FIGS. 7 and 8).

なる。As described above, the front and back neighboring bands 6,
By vibrating the transparent sheets 1.2 to which 7 are welded 8 so as to separate them in different directions, the light-shielding sheet 3 is sequentially peeled off from each cut-out hole 5...5 and separated into individual pieces at a predetermined interval A. As a result, a large number of parallel light-shielding slats 4...4 are formed between the transparent sheets 1.2, and both ends of the light-shielding slats 4 are firmly welded to the transparent sheet side and integrally connected. Therefore, even if the transparent sheet on the front side opposite to the side to which it is attached to the window is moved up and down repeatedly, the light-shielding slat 4 will still be welded at 8 points on the transparent sheet! 7. There is no possibility of leaving. Therefore, the fully open state of the slats when the penetration of light is maximum is as shown in FIG.
is in a state where it is bridged between the transparent sheets 1 and 2 in a substantially S-shape.

容易に分離される好結果を得た。In addition, the cut holes 4 that are bored in the light shielding sheet 3 at a predetermined interval A (which ultimately becomes the width of the light shielding slant 4) are
By making the perforation distance (also called perforation hole) long and making the connection part as small as possible, the cutout hole 4 will not be easily torn when inserted into the transparent sheets I and 2, and after the light shielding sheet 3 is welded and bonded, it will become transparent with a slight force. The most ideal condition is that the sheet should be easily cut when the sheet is pulled up, and in the experiment, the perforation hole was 50 mm, the connection part was 1.5 mm, and the sheet thickness was 0.5 mm. A good result was obtained in which the light-shielding slat 4 was very easily separated from the cut-out hole 4.

ＲＶＣ幾重にも巻回する。The method of manufacturing the blind constructed as above is as follows.
First, a flexible film-like transparent sheet 1.2 (usually a soft transparent vinyl chloride resin film has suitable conditions) cut to match the width of the required window glass is placed between S) and a thin colored light shielding sheet,
- A polymeric film sheet consisting of three layers is formed by sandwiching (interposing in a sandwich-like manner) the sheet 3, and the film is wound into a roll RVC for winding in multiple layers.

遮光シート３には所定の間隔Ａをおいて切取孔５が並列

状に被着して高周波接合を阻止する様にしである。Cut holes 5 are formed in parallel in the light-shielding sheet 3 at a predetermined interval A, and the upper surface 9 and lower back surface 10 near the cut holes 5 are coated with a silicone mold release material Bt- in advance. It is applied in a band shape to prevent high frequency bonding.

溶着される。Therefore, the tripolymerized film sheet in such a state is sequentially pulled out from the take-up roll, and placed on the table of a high-frequency sewing machine as shown in FIG. If high-frequency bonding is attempted in the upper and lower vicinity of the cutout hole 5 using a shaped stamp P, each transparent sheet) 1j
2 and the light-shielding sheet 3, with the cutout hole 5 as the boundary line, the opposite side of the upper surface 9 and the lower back surface 10, that is, the neighboring band 6 is formed above the cutout hole 5, and the neighboring band 7 is formed below the cutout hole 5.
Only the portion that contacts the protruding width P1 of the mold P is welded.

したがって三重合フイルムシートヲ切取孔５の間隔Ａだ
け順次進行させて上述した如き接合を行えば、溶着部分

合されていく。Therefore, if the above-described joining is performed while the triple-polymer film sheet is successively advanced by the distance A between the cutout holes 5, the welded portions will be joined with a predetermined pinch in a staggered manner with the cutout holes 5 as boundaries.

ドを得ることができるものである。After cutting the high-frequency processed film sheet as described above to match the height of the glass window, both transparent sheets 1 and 2 are cut.
By pulling the shading sheets 3 in different directions, the shading sheets 3 are individually peeled off from the respective cutout holes 5...5, and the shading slats 4...4 as shown in FIGS. 7 and 8 are separated from each transparent sheet. 1,
It is possible to obtain a blind made of a completely new synthetic resin film, which is bridged with both ends integrally joined by welding on two sides, and has a refractable light-shielding slat 4 (secondary plate) formed thereon. It is.
