Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pipe shutter that is wound and stored in a spiral shape on a winding shaft.

[Problems to be solved by the prior art and the invention] In general, this type of pipe shutter is often installed in openings such as show windows of department stores and shops because it allows the inside and outside to be seen through.

By the way, a pipe shutter consists of a plurality of pipe bodies arranged in parallel at predetermined intervals, and a plurality of link bodies (connecting fittings) arranged in a direction perpendicular to the pipe bodies. polymerize the ends of adjacent link bodies in the direction perpendicular to
By rotatably inserting the pipe body into the overlapping part, the link bodies adjacent in the perpendicular direction are connected in a series so that they can be wound and stored on the winding shaft in a spiral state bent around the pipe body. It is constructed using shutter curtains connected in a shape. Therefore, although pipe shutters can see inside and outside, they cannot provide decorative or advertising functions to themselves, and therefore cannot satisfy the diverse needs of users.

Therefore, it is proposed to interpose a plate between each pipe body. However, when trying to interpose the plate bodies adjacent to each other on both sides with a pipe body in between, the adjacent plate bodies are similar to the case of link bodies adjacent on both sides with the pipe body in between, When the curtain is unwound from the take-up shaft, it is flat, but when it is wound up on the take-up shaft, it needs to be bent.
For this purpose, a pair of grooves are formed so as to face each other in the pipe bodies on both sides of the adjacent pipe body, and the plate bodies are fitted and supported in these grooves, so that the plate bodies are adjacent to each other on both sides with the pipe body in between. When interposed, the adjacent plate bodies and pipe bodies become fixed, so that they cannot be rolled up and stored.

Therefore, as shown in Japanese Utility Model Application Publication No. 54-132945, grooves formed on both the upper and lower edges of a resin plate are rotatably engaged with the pipe body, thereby making it possible to connect adjacent ones through the pipe body. A system has been devised in which the mating plates can be bent to follow the bending of the link bodies when winding up the curtain, but in this case, the grooves on the plate side fit into the pipe body. Since it is a material, this groove becomes the outermost shell member,
When winding up the curtain, there was a problem in that the groove came into contact with the adjacent shutter curtain and was likely to be damaged.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a pipe shutter that can eliminate these drawbacks. The method is composed of a plurality of pipe bodies arranged in the pipe body and a plurality of link bodies arranged in a direction perpendicular to the pipe bodies, and the ends of the link bodies adjacent in the direction perpendicular to the pipe bodies are overlapped with each other, By rotatably inserting the pipe body into the overlapping part, the link bodies adjacent in the perpendicular direction are connected in a series so that they can be wound and stored on the winding shaft in a spiral state bent around the pipe body. In a pipe shutter using shutter curtains connected in a shape, a pair of concave grooves are formed in each of the pipe bodies so as to face the pipe bodies on both sides of the adjacent pipe bodies, and a pair of grooves are formed in each of the pipe bodies so as to face the pipe bodies on both sides. A plate body is inserted and supported between opposing concave grooves, so that the plate bodies can be inserted adjacent to each other on both sides with the pipe body in between, and each of the concave grooves has a structure in which the shutter curtain is wound up. When rolled up and stored on the shaft, adjacent plates with the pipe body in between can be bent to follow the link body.
It is characterized by providing play for swinging the plate body relative to the pipe body.

With this configuration, the present invention allows the plates to be interposed adjacent to each other on both sides with the pipe body in between, while also allowing the plates to fit into the grooves formed on the pipe body side. It is something.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a pipe shutter that is installed in an opening, and the pipe shutter 1 is wound with a shutter curtain (described later) using a winding shaft (not shown) built into a shutter case 2. The opening can be opened and closed by moving it up and down. 3 is a guide rail.

Reference numeral 4 denotes inner pipes that are arranged in parallel at a predetermined interval in the vertical direction, and 5 is a link body that is arranged facing in the vertical direction perpendicular to the inner pipe 4, and the inner pipe 4 is adjacent to the above-mentioned vertical direction. The link bodies 5 are connected in a series by being rotatably loosely fitted into holes 5a bored in the overlapping ends of the link bodies 5, and thereby the vertically adjacent link bodies 5 are connected to each other in the inner pipe. 4
The winding can be stored on the winding shaft in a spiral state by bending around the inner pipe 4.
An outer pipe 6 is fitted onto the left and right link bodies 5 so as to be positioned between the left and right link bodies 5, thereby forming a double pipe structure and forming the pipe body of the present invention. A groove 6a is formed in each of the outer pipes 6 so as to face the vertically adjacent outer pipes 6, and a groove 5a is also formed in the link body 5.

Further, the overlapping ends of the vertically adjacent link bodies 5 are notched and are fitted so that the left and right end edges of the outer pipe 6 overlap so that they can freely rotate. The outer pipe 6 is configured not to interfere with the link body 5 when the curtain 7 is wound up. By fitting the four peripheral edges of the plate 8 into the grooves 5a and 6a formed in the link body 5 and the outer pipe 6, the left and right movement of the plate body 8 is restricted by the link body 5. In a fixed state, the pipe bodies can be interposed so that they are vertically adjacent to each other with the pipe bodies sandwiched between them. Furthermore, the outer pipe side concave grooves 6a are approximately V-shaped when viewed from the side. The plate bodies 8 are arranged relative to the outer pipe 6 so that the adjacent plate bodies 8 can be bent following the bending of the vertically adjacent link bodies 5 around the inner pipe 4 during curtain winding. It is provided with play that allows it to oscillate.

In the embodiment of the present invention constructed as described above, in order to assemble the shutter curtain 7 of the pipe shutter 1, first, the outer pipe 6 is inserted into the inner pipe 4 through which the link body 5 is inserted, and then After that, the plate body 8 is inserted into the concave groove 5 of the link body 5 and the outer pipe 6.
It can be assembled by repeating the steps of fitting the link body 5 into the inner pipes 4a and 6a, and then inserting the link body 5 into the inner pipe 4 again.

The shutter curtain assembled in this way can have the plates 8 interposed adjacent to each other on both upper and lower sides with the outer pipe 6 in between, and the plates 8 can be completely fitted between each pipe body. For example, it is possible to change the color or translucency of the plate 8,
By changing the material of the plate 8 itself,
Alternatively, by applying a suitable coating to the plate body 8, it is possible to provide a highly variable pipe shutter with desired advertising or decorative functions.

Moreover, in the present invention, the plates 8 can be interposed so that they are vertically adjacent to each other with the pipe body in between, but the upper and lower edges of the plate bodies 8 are inserted into the grooves 6a formed in the outer pipe 6. Since it is installed with some movement play, when the shutter curtain is wound up and stored in a spiral around the winding shaft, the plate bodies 8 that are vertically adjacent to each other with the pipe body in between will move around the inner pipe 4 as the axis. The bending follows the bending of the vertically adjacent link bodies 5, and as a result, the vertically adjacent plate bodies 8 are bent with the pipe body in between, as in the conventional method. Therefore, there is no need to rotatably fit the groove formed on the plate side to the outer periphery of the pipe body, and the pipe body always becomes the outermost shell when being rolled up and stored.
There is no possibility that the plate groove portion is damaged.

Moreover, in this case, since both the left and right sides of the plate 8 are fitted and supported by the grooves 5a on the link body 5 side, it is possible to prevent the plate 8 from moving inadvertently from side to side. This can be prevented by effectively utilizing the link bodies 5 necessary for connecting the pipe bodies, and there is also the advantage that a movement regulating member is not required. However, as shown in FIG. 6, since the link body 9 is plate-shaped, in the case where the groove 5a cannot be formed as in the above embodiment, the bracket 10 can be retrofitted to the plate-shaped link body 9 from the inside and outside using screws 11, etc. It goes without saying that unnecessary lateral movement of the plate body 8 may be restricted by doing so.

Here, it goes without saying that the present invention is not limited to the above-mentioned embodiments, but in short, in the case where plate bodies are interposed adjacent to each other with a pipe body in between,
When bending the adjacent plate bodies following the link body, play is provided in the concave groove formed in the pipe body for inserting the plate bodies to allow the plate bodies to swing, and the adjacent plate bodies are bent together. It is fine as long as it is possible to do so.

[Operations and Effects] In summary, the present invention is constructed as described above, and by inserting plates adjacent to each other on both sides of the pipe body, it is possible to provide the shutter with a variety of decorative functions and advertising. Although the pipe body can be equipped with various functions, the plates adjacent to each other on both sides of the pipe body are attached with swing play in grooves formed in the pipe body. Therefore, when the shutter curtain is wound up and stored in a spiral shape around the winding shaft, the plate bodies adjacent to each other on both sides of the pipe body are bent by the adjacent link bodies that are bent around the pipe body. Since you can follow the pattern and bend it, you can roll it up and store it without any problems. As a result, unlike in the past, it is no longer necessary to bend the adjacent plates on both sides with the pipe body in between, so that a groove formed on the plate side is rotatably fitted around the outer circumference of the pipe body. Therefore, when the tube is rolled up and stored, there is no possibility that the groove portion of the plate fitting outside the pipe body will interfere with each other and cause damage.
