DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a front view illustrating a first embodiment of the present invention, FIG. 2 is a side view thereof, and FIG. 3 is a front view of a unit slat used in the first embodiment. FIG. 4 is an illustrative view showing a part of the hinge portion of the first embodiment in an enlarged manner. FIG. 5 is an essential part illustrative view showing an enlargement of a hinge portion of the shutter shown in FIG. FIG. 6 is an illustrative view showing a bending state in the rail of the shutter of the first embodiment.
[0013]
The shutter 10 is used, for example, as a cover for industrial machines such as machine tools, inspection apparatuses, and experimental apparatuses, household machines, and storage rooms and storages in automatic warehouses. A plurality of slats 12 are connected by a hinge portion 14 so as to be bent. The slat 12 of the first embodiment is a strip-shaped flat plate formed of a material such as a light-transmitting plastic. Therefore, it becomes easy to look inside the shutter 10 from outside the shutter 10. In addition, the shape of the slat 12 is formed in an appropriate size and shape according to the opening / closing port to be attached.
[0014]
The hinge portion 14 according to the first embodiment includes a plurality of annular members 16 each having an annular opening portion having a substantially C-shaped cross section, and an elongated round pipe-like continuous binding member 24 that continuously connects the annular members 16. As shown in FIG. 3, the plurality of annular members 16 are fixed to the edges of the long sides of the slats 12 facing each other in a staggered positional relationship. The annular member 16 is formed to be long at the center portion of the slat 12 and short at the end portion. By comprising in this way, the intensity | strength with respect to the bending in the thickness direction of the slat 12 can be improved. The annular member 16 of the first embodiment is formed of a metal such as aluminum or a synthetic resin.
[0015]
As shown in FIG. 4, an engaging portion 18 having a substantially U-shaped cross section is integrally formed on the outer wall portion of the annular member 16. In the engaging portion 18, the edge portions of one slat 12 facing each other are fitted. A protrusion 20 that protrudes in the thickness direction of the slat 12 is formed on the inner wall of the engaging portion 18. The engaging portion 18 and the slat 12 of the annular member 16 are fixed by, for example, ultrasonic welding, high frequency welding, or an adhesive.
[0016]
As shown in FIG. 5, a cover that covers the gap between the slat 12 and the annular member 16 is formed on the outer wall portion facing the other slat 12 of the annular member 16 fixed to one of the slats 12 facing each other. The part 22 is integrally formed. This cover part 22 also acts as a stopper for limiting the rotation of the hinge part 14. In the example shown in FIG. 5, when one slat 12 and the other slat 12 facing each other are arranged so as to extend on the same straight line, the cover portion 22 abuts on the edge of the other slat 12. The rotation of the hinge part 14 is restricted. In other words, the hinge portion 14 shown in FIG. 5 can change the angle of one slat 12 with respect to the other slat 12 within the range of 0 ° to 180 ° by the action of the cover portion 22. Further, as shown in FIG. 6, the cover portion 22 abuts on the inner wall of the guide rail and acts as a brake that stops inadvertent movement of the shutter 10. In addition, when one slat 12 and the other slat 12 are opened as much as possible, when the cover portion 22 abuts on the edge of the other slat 12, the cover between the two does not become 180 °. The portion 22 may be formed. In that case, when the shutter 10 is slid into the guide rail, which will be described later, the friction between the inner wall of the guide rail and the shutter 10 increases, so that a braking action that stops the shutter 10 from sliding freely is provided. It will increase further.
[0017]
The slats 12 facing each other are arranged such that the rings of the plurality of annular members 16 provided alternately communicate from one end to the other end of the slats 12. The plurality of annular members 16 are inserted with a long and narrow round pipe-shaped continuous binding member 24 from one end to the other end of the slat 12. As a result, the slats 12 facing each other are connected to each other so as to be bent at the hinge portion 14. Moreover, since this annular member 16 is provided with a notch, it is possible to absorb a dimensional error. In addition, the continuous binding member 24 of 1st Example is formed, for example with stainless steel.
[0018]
Further, in the shutter 10 of the first embodiment, as shown in FIG. 6, a line passing through the center of the thickness of each slat 12 extends between the centers of the rings of the annular member 16 disposed on both sides of the short side of the slat 12. The engaging portion 18 and the cover portion 22 are formed so as to be disposed outside the shutter 12 with respect to the connecting line. This is because, as shown in FIG. 6, when the shutter 10 is bent, it is bent with a smaller radius.
[0019]
Furthermore, as indicated by broken lines in FIG. 5, end caps 26 are fitted to both ends of the slat 12 in the width direction. Furthermore, as indicated by broken lines in FIG. 5, end caps 26 are fitted to both ends of the slat 12 in the width direction. The end cap 26 includes a circular umbrella portion 26 a having a diameter larger than the diameters of both ends of the hinge portion 14, and the outer periphery of the umbrella portion 26 a is provided to slide on the inner surface of the guide rail 28. Thereby, opening and closing of the shutter 10 can be performed smoothly.
[0020]

Arranged and configured. The end portions of the H-shaped body 38 and the T-shaped body 40 are abutted with each other, and the connecting small piece 42 is brought into contact with the back surface portion, and is fixedly connected by screwing or welding. With such a structure, the guide rail 28 can be fixed to the housing 30 without causing an obstacle such as a tip of a screw to protrude from the track portion in the guide rail 28.
[0022]
As shown in FIG. 1, the shutter 10 is provided with a handle 44 for the user to put on the front of the slat 12 disposed at the lowermost end. Further, a brake portion is provided on the slat 12 at the lower end of the shutter 10 shown in FIG. The brake portion 46 is formed so as to be constantly biased from the slat 12 toward the inner wall of the guide rail 28. This urging is performed by using the elastic restoring force of the synthetic resin body itself constituting the brake portion 46 or a leaf spring. When opening and closing the shutter 10, the shutter 10 can be slid up and down by applying a predetermined force against the urging force of the brake portion 46. When the hand is released from the shutter 10 during opening and closing, the brake portion 46 is pressed against the inner wall of the guide rail 28 by the urging force, so that the shutter 10 stops against its own weight during opening and closing.
