Description

[Detailed description of the invention] <Industrial field of application> The invention is a folding door in which the front and rear parts of each door body protrude evenly to the left and right around the rail, and the folding door can be folded according to the direction of movement of the door. This invention relates to a telescoping folding door that can be smoothly opened and closed by a horizontally rotatable door wheel that moves forward and backward and rotates on a rail.

<Prior Art> Most conventional folding doors such as gates are of a type in which the door body 1 is folded to one side of the rail 2, as shown in FIG. If the doors are folded to both sides, the door rollers will be located in the center of each door body, and the doors will not operate smoothly until they reach a certain angle when they are opened or closed, creating resistance. Therefore, the door of the type that can be folded to one side as shown in the figure has the advantage that the protruding parts of the door body bend and extend without creating any resistance at the hinge fittings 3, so that opening and closing is not very difficult.

<Problems that the invention seeks to solve> By the way, conventional folding doors that fold to one side tend to be unstable because the center of gravity is shifted to one side, which causes the door body to swing or fold quickly when activated. The problem was that the entire door protruded only on one side, which required a corresponding amount of space.

<Means for Solving the Problems> The present invention has been developed in view of the above-mentioned prior art, namely, a plurality of door bodies 1 are connected via hinge fittings 2, and each door body 1 is provided at the lower end in the middle. fixed money 3
The slide ring 6 is engaged with the rail 1 at the lower end of the slide ring 6.
The mounting bracket 9 of the door wheel 10 that connects to the top of the door wheel 1 is rotatably supported, and the rear end of the support 12 whose tip is pivoted to the rear of the end door body 1 is attached to the bracket 14 attached to the fixed column 13. It is an object of the present invention to provide a telescoping folding door which does not suffer from the disadvantages mentioned above due to its pivoting structure.

<Function> Figure 1 shows the folding door in a closed state.
Since each door body 1 is flush, the whole body is extended in a straight line, and the door body at the tip faces the fixing post 16 at the end and is fixed with a drop rod 15.

To open the door from this state, first pull up the drop bar, then lightly press a part of the door body to bend it and open the tip of the door body toward the fixed pillar 13. Then, the entire folding door is folded in a zigzag shape around the rail 11 as shown in the second figure. At this time, since the mounting bracket 9 is rotatable, the door wheel 10 rolls on the rail 11 depending on the orientation of the door body 1, but in particular, the sliding bracket 9, which pivotally supports the mounting bracket 9, responds to the movement of the door body. As it moves along the fixing metal 3, the fulcrum moves, and therefore, there is no resistance against each door body, and together with the bending of the hinge metal fitting 2, each door body bends in a direction perpendicular to the rail. As the door is folded, the support 12 pivotally connected to the end door also bends around the support 14 and overlaps with the door, so that the entire structure contracts in parallel and the door is completely opened (see FIG. 3).

To close the door, the tip door body is pulled out and run on the rail 11 toward the fixed pillar 16 at the end, contrary to the above. Then, the door body 1 sequentially extends, but at this time, the movement of the sliding metal 6 avoids the resistance of the door body from trying to push it up in the diagonal direction, so it runs smoothly and finally as shown in the first figure. completely closed.

<Example> In the figure, four door bodies 1... are upper and lower hinge fittings 2
They are connected to each other so that they can bend and expand, and a horizontally long fixing metal 3 is fixed to the lower end of the center of each door body. A horizontal shaft 4 is provided protruding from the left and right sides of the center portion of the fixed metal 3, and a rotary wheel 5 is mounted on the left and right lower ends of the front and rear parts. A horizontally elongated sliding metal 6 with a concave side face faces the fixed metal 3 from below, and the horizontal shaft 4 of the fixed metal engages with long holes 7 bored on the left and right sides of the sliding metal 6, and the rotary wheel 5 slides. It is in contact with the inner bottom surface 6a of the moving metal. In addition, a mounting bracket 9 with an inverted concave side surface is rotatably provided on a shaft 8 protruding from the central lower end of the sliding bracket 6, and two door rollers 10, which are mounted on this mounting bracket, roll into contact with the rail 11. ing.

Therefore, on the back side of the end door body 11, there is a 1/4th of the door width at a position corresponding to 1/4th of the door width from the end of the door body.
A supporting body 12 having a long length is pivoted at two places, upper and lower, and the rear end of the supporting body 12 is attached to a receiving plate 1 attached to a fixed column 13.
It is pivoted to 4. That is, the engagement alloy 17 fixed to the back side of the door body and the tip of the support body 12 are engaged in a hinge shape, the rear end of the support body and the receiver 14 are also engaged in a hinge shape, and the support body 12 is engaged with the support body 12 in a hinge shape. It opens and closes in response to the movement of the An elastic stopper 18 is fixed to the rear end of the back side of the terminal door body 1, and when the door is closed (extended), it engages with the upper surface of the support 12 to suppress the movement of the door and also to open the door. It is designed to automatically detach from the support body 12 when the case is reached.

FIG. 1 shows the door in its fully closed state. At this time, the front door body 1 faces the rear end fixing column 16 and the drop bar 15 protrudes downward and is fixed, and the rear end door body 1 has the stopper 18 as a support. 12, so that the entire folding door is fixedly extended. From this state, when the drop bar 15 is pulled up and the tip door body is lightly pushed in the bending direction, the hinge fittings 2 act to bend the entire folding door substantially uniformly, and the stopper 18 is moved away from the support body 12 by momentum. Then, when the tip door body 1 is further pushed open, the folding door is folded around the rail 11 with the left and right sides protruding evenly, but at this time, each door body 1
... produces an effect of trying to stretch in the direction of bending. In other words, when the door wheel 10 in the center is in the fixed position, the door does not open smoothly due to the tension between the door bodies, but the sliding door engaged with the fixing metal 3 attached to the lower end of the door body does not open smoothly. The moving ring 6 moves forward and backward parallel to the door body by the rotation of the rotary wheel 5 made of a fixed metal while the elongated hole 7 plays along the shaft 4. Therefore, the door wheel 10 located below the sliding ring 6 moves forward and backward in parallel with the door body. It can move forward and backward according to the movement, and therefore, the resistance of the door body 1 is eliminated and the entire door is quickly folded by the door roller rolling on the rail (see 2). Finally, as shown in the third figure, the entire door is folded up substantially at right angles to the rail, and the support body 12 is also positioned parallel to the end door body 1, so that the door contracts and becomes fully open.

When closing the door, the front door body 1 is pulled out and moved toward the end fixed post 16, and the door roller 10 rolls on the rail 11, and the door body 1 is extended via the hinge fittings 2 in the reverse order to the above, and the support body 12 is positioned behind the straight end door body 1, so that the gate opening is neatly closed by the door body.

<Effect of invention> The present invention exhibits the following unique effects.

(1) Since the door roller can move forward and backward together with the sliding metal, even if the door body generates tension-like resistance when bending or extending, the resistance is avoided by moving the door roller position and the door operates smoothly. Therefore, opening and closing operations can be performed smoothly, and when a part of the door body is bent, the whole door is bent at the same time, so that folding can be done quickly.

(2) Since the door roller running on the rail is located in the middle of each door body, the folded door body protrudes evenly to the left and right sides of the rail, resulting in an extra protrusion on only one side. There is no fear, and since the center of gravity of the door body does not shift to one side, there is no shaking or tilting when opening and closing, so there is a sense of stability.

(3) Since the folded door bodies are arranged parallel to each other in an overlapping manner and are located perpendicular to the rail, a wide opening is secured on the rail, allowing for plenty of room for cars, etc. to pass through.

(4) It can be used not only as a folding gate or partition door, but also as a hanging door by providing an upper rail.
