Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a horizontally drawn pipe shutter that is installed in an opening in a building.

[Problems to be solved by the prior art and the invention] Generally, there are cases where a storage space is provided only on the side of an opening in a building rather than above the opening.
For such openings, a so-called horizontal shutter is used, which opens and closes the shutter in the horizontal direction.
For this reason, horizontally drawn pipe shutters are also used in stores, etc., in which the outside of the shop window is surrounded by pipe shutters so that the store can be seen from the outside even after the store has closed. However, since the above-mentioned horizontal pulling type pipe shutters have not yet been widely used and standardized, parts have been manufactured and assembled in factories each time an order is received.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a horizontal pulling type pipe shutter that can eliminate these drawbacks. In a horizontally drawn pipe shutter, which is constructed by connecting a plurality of vertically arranged pipes in a lattice shape using connecting links, the upper and lower ends of a pair of adjacent left and right pipes have swings at both left and right ends. The left and right corresponding ends of the upper roller bracket and the lower roller bracket, each equipped with a stop roller, are attached to connect the upper and lower ends of adjacent pipes in a bridge-like manner, and the left and right anti-sway rollers of the lower roller bracket are also installed. It is characterized in that a running roller is rotatably provided between the two.

With this configuration, the present invention can be easily manufactured using a conventional lightweight pipe type shutter or the like.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawing, numeral 1 is a shutter curtain of a horizontally drawn pipe shutter, and numerals 2 and 3 are upper and lower guide rails having a substantially U-shaped cross section. The shutter curtain 1 has a plurality of core metals 5a arranged vertically in parallel, each having a length corresponding to the height of the opening.
Pipes 5 of predetermined dimensions and connecting links 6 are inserted alternately into the lattice to form a connection. For example, the connection between the connecting links 6 is one piece as shown in Fig. 2.
Two pieces and one piece are installed alternately. In order to prevent the connecting link 6 and the pipe 5 from slipping down during opening and closing movement of the shutter curtain 1, the pipe 5 is fixed to the core bar 5a by suitable fixing means such as rivets. Reference numeral 7 denotes a vertical bar attached to the opening side of the shutter curtain 1, and the vertical bar 7 is provided with a handle 7a for opening and closing. Shutter curtain 1
The winding side of the winding shaft 11 is vertically rotatably supported in the center of the storage case 4 through a hanging base 10.
is fixed. The winding shaft 11 is equipped with a spring or the like that biases it in the winding direction. Reference numeral 12 denotes a rotary disk integrated with the winding shaft 11, so that the shutter curtain 1 wound on the winding shaft 11 is placed and guided on the spiral guide groove 12a of the rotary disk 12. It's getting old.

Further, 8 is an upper roller bracket, and 9 is a lower roller bracket, and the upper and lower roller brackets 8 and 9 each have two short tubes 8a and 9a, and a connecting rod 8.
b, 9b and steady rest rollers 8c, 9c. The inner and outer diameters of the short tubes 8a and 9a are set to the same dimensions as the pipe 5, and the two short tubes 8a and 9a are separated by connecting rods 8b and 9b at intervals of the same size as the hole pitch p of the link 6. are connected as one body. Further, the anti-sway rollers 8c, 9c are rotatably mounted on the outside of the short tubes 8a, 9a (in the direction of the upper and lower ends of the pipe 5).
Further, inside the center of the lower connecting rod 9b, a running roller 9d with a horizontal axis is rotatably provided.
As shown in FIG. 2, the upper and lower roller brackets 8 and 9 are inserted from the upper and lower ends of the two adjacent pipe cores 5a, and fixed to the cores 5a at the short tubes 8a and 9a using appropriate fixing means such as rivets. In this way, the upper and lower ends of the adjacent pipes 5 are connected by the upper and lower roller brackets 8 and 9 in a bridge-like manner.

In the embodiment of the present invention constructed as described above, when opening the opening from a state where it is fully closed by the built-in shutter curtain 1, first remove the lock (not shown) and then open the shutter curtain vertically. When the handle 7a provided on the crosspiece 7 is held and pulled toward the storage case 4 side, the shutter curtain 1 is moved toward the storage case 4 side by rotating the running roller 9d together with the biasing force built into the winding shaft 11. start. At this time, to prevent the pipes 5 and roller brackets 8, 9 at the upper and lower ends of the shutter curtain 1 from rubbing within the guide rails 2, 3, the anti-sway rollers 8c, 9c contact the inner walls of the upper and lower guide rails 2, 3, respectively, and rotate. The guide is designed to keep frictional resistance as low as possible. Inside the storage case 4, the running roller 9d of the shutter curtain 1 to be wound up first rolls into the spiral guide groove 12a provided on the rotating disk 12, and the shutter curtain 1 is rolled up on the rotating disk 12 integrated with the winding shaft 11. While supporting the own weight of the tar curtain 1, it becomes easy to be wound up, and is rotated and wound onto the winding shaft 11. When closing the shutter curtain 1, hold the handle 7.
If you pull it out of the storage case 4 by holding the handle a, the traveling rollers will rotate while being guided by the upper and lower guide rails 2 and 3, and it will be fully closed.

As described above, the present invention makes it possible to provide a horizontally drawn type pipe shutter by an extremely simple process of simply providing roller brackets 8 and 9 on the upper and lower sides of the shutter curtain 1.

[Operations and Effects] In short, the present invention is constructed as described above, so a roller bracket having anti-sway rollers at both left and right ends is manufactured to match the pipe pitch, and by using the roller bracket, By connecting the upper and lower ends of adjacent pipes in a bridge-like manner, it is possible to easily incorporate a horizontally drawn pipe shutter using a conventional shutter curtain. Further, since the upper roller bracket can be used without the traveling rollers of the lower roller bracket, it is possible to standardize the roller bracket, and the number of parts can be reduced, thereby improving the efficiency of inventory management.
