DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting folding door which moves while being guided by two rails and has a reduced overall length at a storage position and can be used for a gate or a shutter.

[0002]

2. Description of the Related Art In addition to sliding doors and double doors, gates include those that expand and contract. As shown in FIG. 9, the telescopic gate generally has a plurality of rectangular frame members 50, each of which has a link member 52 and is connected to each other by a pin. There is a point 54, and the link member 52 expands and contracts like a pantograph, so that the gate as a whole expands and contracts. The lower part of the frame member 50 is provided with a caster 55, and some of them run on the ground as they are, while others run by being guided by rails laid on the ground.

[0003] Such a telescopic gate is extremely unstable when stopped in a half-open state, and may be inclined by the wind or expand and contract by itself. In the first place, the connection structure using the pantograph mechanism has a complicated structure, is easily broken, and is not sufficiently strong, and is installed only in a narrow frontage of about 3 m at most.

[0004] In addition to this, there is a door that is generally called an folding door as a door that expands and contracts. As shown in FIGS. 10A and 10B, a folding door is formed by connecting two or more door plates 56 with a hinge 57 so as to be bent. The door plate 56 is provided and guided by the upper and lower rails 59 so that the door plate 56 can be closed, folded, and opened. Such folding doors are not self-supporting, and cannot be used as gates because rails 59 are always required above the door plate 56, and their applications are limited mainly to bathroom entrances and closet doors.

[0005]

DISCLOSURE OF THE INVENTION The present invention is self-supporting, maintains a stable configuration even in a half-open state, does not wastefully occupy a wide space when the door is released, and has a wide frontage. An object of the present invention is to provide a connecting folding door that can be used for a wide range of applications such as a gate and a shutter.

[0006]

In order to achieve the above object, a connecting folding door according to the present invention forms a folding screen type folding door body by connecting a number of vertically long doors with hinges between long sides thereof. A caster is provided at the lower end surface of the folding door main body, and the caster is guided by two rails installed in parallel along the longitudinal direction of the folding door main body so that the folding door main body moves, and any position in the longitudinal direction of the rail is provided. In addition, the space between the rails is wider than the other parts to provide a storage space for the folding door body, and the folding door body connects every other bent part.
The auxiliary connection member has an auxiliary connection member,
Bent when the rails are in a narrow range
Keep the distance between them constant and reduce the force to move the folding door itself.
It is characterized by being transmitted linearly along the rule .

Since the folding door body is always used while being folded into a folding screen type, it is self-supporting, resistant to external forces such as wind, and can be used for a gate with a wide frontage. The rails need not necessarily be straight as long as they are parallel to each other, and may be arcs. The folding door itself is extendable and contractible, but the degree of expansion and contraction is determined by the interval between the two rails. By increasing the interval, the folding door body shrinks to shorten its length, and conversely, expands when the interval is reduced. The storage space can be at any position in the longitudinal direction of the rail, but it is basically located at the end of the rail.When the gate is opened by moving the folding door to the corner, the folding door shrinks automatically. It is stored compactly. The door may be a plate-like member, or may be a lattice-shaped member made of a shape material such as an aluminum alloy.

In the case of a gate or the like where the height of the folding door main body is not so high, the rails may be provided only below the folding door main body, but two rails and casters are similarly installed above the folding door main body. If so, it can be used for tall items such as garage shutters.

[0009] The folding door main body moves integrally like a sliding door by pushing or pulling the front or rear door by hand. In this case, Orito because the body is a folding screen type, the
As it is, the force propagates zigzag through the inside, and when the folding door body is long and heavy, the hinges and the bases of the casters may be overloaded. According to the present invention, there is provided an auxiliary connecting member.
As a result, the force is transmitted linearly, so that the folding door body can be moved smoothly, and failures can be reduced. The auxiliary connecting member may be a chain or a belt,
It only works when the folding door body is moved in the pulling direction, so it is better to use something like a bar that bends in the middle to act on both pushing and pulling.

1 to 5 show an embodiment used as a gate. The folding door main body 3 is formed by connecting a number of vertically long doors 1 with hinges 2 at left and right side edges, and forming a folding screen. Each door 1 is formed by assembling an aluminum alloy profile. A caster 4 is attached to the lower end of each door 1 at the same position toward the end. The caster 4 is a free caster with no eccentricity that can swing its head. When the arrangement of the casters 4 of the folding door body 3 is viewed as a whole, the casters 4 are arranged on two parallel straight lines.

On the ground, a guide 2 for guiding the casters 4 is provided.
The rails 5, 5 are laid in parallel. The rail 5 is provided with a groove that is somewhat wider than the width of the wheels of the casters 4. Further, as shown in FIG. 1, the rails 5 are provided with non- parallel portions 10 in the shape of a letter "C" to increase the distance between the rails at the left end in the figure. When the folding door body 3 passes through the non- parallel portion 10, the angle of the bent portion by the hinge 2 changes, and the entire length expands and contracts. The place where the interval between the rails 5 and 5 is widened serves as a storage space for the folding door main body. Here, the folding door main body is stored compactly with the bent portion tightly bent. In the illustrated example, the non- parallel portion 10 changes the distance between the rails by bending both the rails 5 and 5,
Only one of the rails 5 may be bent.

The above is the basic configuration of the connecting folding door of the present invention. Next, additional mechanisms will be described. The folding door body 3 moves on the rails 5 and 5 while being folded in a folding screen shape by pushing and pulling by hand. At that time, the propagation of force is made linearly, For the purpose of encouraging smooth movement, as shown in FIGS. 1, 2, and 5, every other bent portion of the folding door body 3 is connected by a stick 6. The strut 6 connects the two connecting arms 11a, 11b with pins 12, and can swing the ends of the arms 11a, 11b in the horizontal plane through the brackets 13, 13 on the side edges of the doors 1, 1. It is pivotally supported. The strut 6 is connected to the upper connecting arm 11 so that the strut 6 does not bend outward from the state where it is completely extended.
A stopper 14 is provided on the edge of a. When the folding door body 3 is in the closed position, the tension bar 6 is stretched straight and stretched to maintain the shape of the folding door body 3, and is folded inward when in the open position, that is, in the storage space. .

When the gate is opened (when the state is shifted from the state shown in FIG. 1B to the state shown in FIG. 1A), when the folding door main body 3 passes through the non- parallel portion 10, the above-mentioned strut rod 6 is released. I need to break it. Therefore, the pin 12 connecting the connecting arms 11a and 11b is extended downward to support the roller 15 at the tip, and the inclined guide 16 is installed on the ground, and the roller 15 hits the inclined guide 16 and is pushed away. As a result, the strut 6 is automatically broken.

FIG. 6 shows another embodiment. In this embodiment, the belt 8 is passed horizontally in the longitudinal direction while passing through a guide 7 provided at a bent portion of the folding door main body 3, and the leading end is positioned at the top. The belt 8 is fixed to the door 1, and the belt 8 is wound by a winding device 9 installed in a storage space of the folding door body 3.
The gate can be opened automatically. The take-up device 9 includes a motor 17 and a take-up reel 18. When an operation button 19 is pressed, the motor 17 is activated, the take-up reel 18 rotates, the belt 8 is taken up, and the folding door body 3 is drawn. The gate is manually closed.

The guide is hinged 2 as shown in FIGS.
Of the door 1 and two sub-rollers 22, 22 protruding laterally from the side end surface of the door 1 so that the bent portion has a fixed angle. When opened, as shown in FIG. 7 (a), the belt 8 is sandwiched between the three rollers 21, 22, 22 and locked, and when the bent portion is closed, as shown in FIG. Since the rollers 22 are separated from the main roller 21, the belt 8 is in a free state. By having this mechanism, the belt 8 works in the same manner as the above-described strut 6, and the force is efficiently transmitted through the belt 8, so that the gate can be opened and closed smoothly.

Although the drawings only show the form of a gate provided with a rail only below the folding door main body, if a rail is provided on the folding door main body and guided in the same manner, it can be widely used as a shutter for a garage or the like. Can also be used for openings.
