Description

[Detailed Description of the Invention] The present invention relates to a shutter, and more specifically, in a shutter body composed of hinged and foldable rectangular flat plates, each rectangular flat plate can be rotated relative to an adjacent rectangular flat plate. This invention relates to a simple horizontally-pulling shutter that can be used as a rudder to form a flat plate, or can be made freely foldable by releasing the non-rotatable state.

2. Description of the Related Art Conventionally, a foldable horizontal shutter is known in which a main body of a shutter, in which the side edges of a rectangular flat plate are hinged, is suspended from a hanger rail attached to the ceiling of a building.

However, since the above-mentioned horizontal sliding shutter has a plurality of rectangular flat plates that are hinged to each other so that they can rotate freely, it tends to move easily during installation and is unstable, especially when used outdoors. This causes problems such as shaking and making noise, and not being able to install it flatly, which damages the appearance.

The present invention is an attempt to solve the above-mentioned difficulties of the conventional horizontal shutter, and its purpose is to make the main body of the horizontal shutter freely foldable and fixed in a flat plate shape. In a foldable horizontal shutter that moves along a hanger rail by hingedly connecting the side edges of a plurality of flat plates, the hinged side is placed at a fixed position from the floor at the bottom of each flat plate. Sleeves are provided horizontally in pairs with their edges sandwiched in between, and each pair of sleeves is provided with a rod-shaped bolt that can be freely connected and detached, and an operating protrusion is provided on this rod-shaped bolt. A slit is provided and the actuating protrusion protrudes from the slit, and an elastic member is fixed to the floor so as to face the locus of the actuating protrusion as the shutter moves. When moving, the actuating protrusion is actuated by an elastic member while sliding in the slit, and after the actuating protrusion comes into contact with the end of the slit, the elastic member is deformed and adjusted so that the actuating protrusion passes through the slit. The purpose is to provide a pull shutter.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

In the drawing, 1 is a shutter body;
is made up of a plurality of rectangular flat plates 2 arranged so as to form a plane, whose side edges are hingedly connected to each other at the back surface by hinges 3, and each rectangular flat plate 2 is rotatable in a fixed direction.

4 is a well-known runner attached to each rectangular flat plate 2 constituting the shutter body 1, and as shown in FIG. It is suspended vertically so that it can rotate freely.

Casters 6a and 6b are selectively attached to the lower end of the rectangular flat plate 2, and slide and rotate on both sides of the lower rail 1, which is a vertical plate laid along the floor of the building on which the shutter body 1 moves. It is attached in an inverted eight-shape slanted position.

Reference numeral 8 denotes a cylindrical sleeve attached to the vicinity of both side edges of the lower end of the back surface of each square plate 2, and is welded in a straight line onto the flange portion 9 formed at the lower end of the back surface of the square plate 2 so that the central axes thereof coincide with each other. ing.

Note that the sleeve 8 is not necessarily cylindrical, and may be square cylindrical.

Reference numeral 10 denotes a guide slit of a predetermined length provided horizontally at the same height on the front surface of the sleeve 8, and is formed by cutting out the side edge side of the rectangular flat plate 2 of the sleeve 8.

Reference numeral 11 denotes a rod-shaped bolt, which is slidably inserted between a pair of sleeves 8 provided on adjacent rectangular flat plates 2.

Reference numeral 12 denotes an operating protrusion fixedly installed slightly closer to one end than the center of the bolt 11, which is connected to the guide slit 1 of the sleeve 8.
The horizontal movement range of the bolt 11 is restricted by the slit 10 and the actuating protrusion 12.

Reference numeral 13 denotes an elastic member made of a coil spring, and its lower end is fixedly supported by a fixing member 14 at a predetermined position on its trajectory so as to come into contact with the operating protrusion 12 that moves as the shutter body 1 moves.

The elastic strength of the elastic member 13 is such that while the actuating protrusion 12 slides within the slit 10 when the shutter body 1 moves, the false protrusion 12 is actuated by the elastic member 13, and the actuating protrusion 12 moves through the slit. After coming into contact with the end of the actuator 10, the elastic member 13 is deformed so that the actuating protrusion 12 can pass through.

Note that the elastic member 13 only needs to be in a position where it can come into contact with the actuating protrusion 12, and may be provided so as to make contact with the actuating protrusion 12 from the side or above.

Further, the guide slit 10 may be provided not only on the front surface of the sleeve 8 but also on the upper surface or the lower surface.

Furthermore, it goes without saying that the elastic member 13 is not limited to a coil spring, and may be any other suitable member such as a plate spring.

The present embodiment is constructed as described above, and as shown in FIGS. 2 and 3, as the shutter main body 1 moves, the operating protrusion 12 fixed to the bolt 11 is located on the passage of the elastic member 13. The bolt 11 slides within the sleeve 8 in a direction opposite to the advancing direction of the shutter main body 1, and stops when the operating protrusion 12 comes into contact with the end of the guide slit 10.

Furthermore, the shutter body 1 resists the elastic force of the elastic member 13.
By moving the bar 11, subsequent bolts 11 can be sequentially moved in the same manner.

The solid line in FIG. 2 represents the connected state, that is, the state in which the bolt 11 is inserted between the opposing pair of sleeves 8 and the adjacent rectangular flat plate 2 cannot be rotated, and the two-dot broken line represents the state in which the shutter body 1 This shows a state in which the bolt 11 is disengaged by the movement of , and the arrow indicates the direction in which the shutter body 1 moves.

Note that the elastic member 13 can be attached at a folded position on the side where the elastic member 13 is attached, for example, when the banger rail 5a of the extended portion of the shutter and the banger rail 5b of the storage portion form a right angle as shown in FIG. The appropriate location is near the front of the curve.

When the shutter main body 1 moves toward the extension section, the bolts 11 become engaged, and when the shutter main body 1 moves toward the storage section, the bolts 11 are disengaged. Place.

In this way, the shutter main body 1 forms an integral plane when it is extended, and when it is stored, the rectangular flat plates 2 forming the shutter main body 1 can rotate in a fixed direction, and the shutter main body 1 forms an integral plane.
can smoothly pass through the bent portion of the non-ger rail 5.

As shown in FIG. 5, the guide slit 10 is provided only on one side of the sleeve 8 and is formed into a long hole, and the actuating projection 12 is moved within this long hole to engage and release the bolt 11. You can do it like this.

In this case, the tip of the operating protrusion 12 and the bolt 11 are
Threads are pre-cut in the designated places of the bolts 11.
It is necessary to adopt a fixing method such as inserting the actuating protrusion 12 into the sleeve 8 and then screwing the actuating protrusion 12 thereon.

In the embodiment described above, the hinge 3 for hinge-coupling the rectangular flat plate 2 is provided on only one side of the shutter body 1 so that the rectangular flat plate 2 can rotate only in a fixed direction. The method is not limited to this, and an accordion-type shutter may be formed by hinge-joining one side edge of the rectangular flat plate 2 at the back and the other side edge at the front.

The explanation of the operation in this case is also omitted because it is the same as that of the above-mentioned embodiment.

In this way, according to the present invention, the rectangular flat plates constituting the shutter body can be integrally fixed in a flat shape by simply moving the shutter without requiring any special operation, and each rectangular The shutter body can be bent by rotating the flat plates, so when it functions as a shutter, it is sturdy and has an excellent appearance, and it also has great effects such as being able to be stored smoothly. .

Although various explanations have been given above with reference to preferred embodiments of the present invention, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is.
