Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a folding door used for installation furniture or a room partition.

[0002]

[Prior art]

 Due to the effective use of the room and the increase in storage capacity, a large amount of stationary furniture has been used, where part of the room is dressed in clothes or a cupboard. Since the fixed furniture has a large entrance and exit, if you use a so-called "double door" that uses two doors, one door will become large, and when you open the door you will not only hit the objects around the fixed furniture but also the female. It is difficult for children and children to handle.

Therefore, recently, many folding doors have been widely used that can open the entrance without opening the door wide. The folding door is made by connecting multiple doors with hinges, so that when the folding door is opened, the connecting portion is folded like a bye.

[0006] Further, folding doors may be used for dividing a large room to increase the number of rooms, or for partitioning a large room into small rooms so that a small number of people can easily use it.

In a conventional folding door, a plurality of doors are connected by a hinge, a traveling roller is attached to the upper or lower portion of the door, and the traveling rollers travel on rails laid on a duck or a sill. ing.

Since a traveling roller attached to a recent folding door has good traveling properties, the folding door can be easily opened and closed without applying a large force.

As the hinge installed on the folding door, when the door is closed, that is, when a plurality of doors are all in a flat state, a spring is biased in the closing direction so that the hinge is completely flat. There is. In such folding doors with hinges, even if the folding doors are not applied with force until they are completely closed, when they are about to close, the spring force causes the multiple doors to completely close and become flat. .

[0008]

[Problems to be solved by the device]

 By the way, in the folding door, when the door is opened, the connecting part comes out forward and you can see the side of the door. And when closing the doors, the sides of the two doors close like scissors. Therefore, when the folding door is closed, if a finger is placed on the connecting portion, it may be pinched between the side surfaces of the two doors to be closed like scissors. In particular, a folding door equipped with a spring-biased hinge moves quickly before closing and closes before the finger can be pulled out, resulting in an accident of pinching the finger.

Further, when the folding door is used as a partition of the room, the conventional folding door leaks the light of the adjacent room, which reduces the effect of partitioning.

An object of the present invention is to provide a folding door that does not have fingers caught when it is closed and does not leak the light of the adjacent room even when it is used as a partition.

[0011]

[Means for Solving the Problems]

 The present inventors have completed the present invention by paying attention to the fact that if there are inclusions at the connecting portions of a plurality of folding doors, the inclusions can prevent the intrusion of fingers and the inclusions can block the light. .

According to the present invention, in a folding door in which a plurality of doors are connected by a hinge, it is difficult for a finger to enter the connected portion of the plurality of doors, or the plurality of doors come into contact with the fingers before they are completely closed. It is a folding door characterized by being installed between the side faces of a plurality of doors that are connected to each other by a shield that makes it possible to detect when the door is closed.

The shield used in the present invention includes a bellows at a connecting portion of a plurality of doors for preventing fingers from being caught when the folding door is closed, or a spring-loaded projecting piece at the connecting portion. It is like placing it and retracting it when the folding door closes.

[0014]

[Action]

 The bellows has narrow creases, so it is difficult for fingers to enter between the folds. When the folding door is closed, the spring-loaded projection piece hits the finger in a half-closed state, and therefore, there is a danger of pulling the finger out of the connecting portion. Furthermore, if the bellows and the protruding pieces are connected in series, they block the light and prevent it from leaking to the next room.

[0015]

【Example】

 The present invention will be described below with reference to the drawings. 1 to 4 show a folding door according to a first embodiment of the present invention, and FIGS. 5 to 8 show a folding door according to a second embodiment of the present invention.

First, the folding door of the first embodiment will be described. In the folding door, two doors 1 and 2 are connected by a hinge 3. A roller (not shown) is installed on the upper or lower part of the folding door, and the roller runs on rails laid on the fixed furniture or shelves or sills of the shelves to facilitate opening and closing of the folding door.

In the first embodiment shown in FIGS. 1 to 4, a bellows 6 is installed as a shield between the side surfaces 4 and 5 of two doors 1 and 2 connected by a hinge 3. It is desirable that the vertical length of the bellows 6 be substantially the same as the height of the door. This is to prevent the fingers of the person who opens and closes the folding door from being caught in any part of the bellows, and it is better to block the entire connecting part as much as possible to prevent the light of the adjacent room from leaking. Because.

The bellows 6 is provided with mounting portions 7, 7 on both sides. A wedge-shaped fixing piece 8 having a step is formed on the attachment portion on the side opposite to the bellows portion.

The bellows 6 is for attaching each mounting portion to the side surface of each door. To attach the bellows-shaped fixing piece formed, a groove into which the fixing piece 8 can be inserted is formed on the side surfaces 4, 5 of the door. Then, the fixing piece is inserted into the groove and fitted and fixed. Since the fixing piece has a wedge shape with steps, it prevents the steps from coming off after being inserted into the groove. To attach the bellows mounting portion to the door, the mounting portion may be directly attached to the side surface of the door with a screw or an adhesive instead of the wedge-shaped fixing piece.

FIG. 3 shows a state in which the folding door of the first embodiment is completely opened, and the two doors 1 and 2 are parallel with their wide faces facing each other. In this state, the bellows 6 installed between the side surfaces of the two doors are spread like a fan-shaped fan with the bent portions being widened. At this time, since the concave portion formed by each bent portion of the bellows is widened, the finger can be easily taken out even when the finger is inserted between the bellows.

2 and 4 show a state in which the folding door of the first embodiment is being closed, and the two doors 1 and 2 are at an angle of about 90 degrees. In the bellows 6 installed between the side surfaces of the two doors, the space between the bent portions is smaller than that in the fully opened state in FIG. In this state, the fingers do not enter, so even if the folding door is closed, the fingers will not get caught. Also, even if you try to close the folding door with your finger in the recessed part in the state where the bent part in Fig. 3 is wide, you can see that your finger is caught in the middle of this step, and you notice the danger here. You will pull out your finger.

FIG. 1 shows a state in which the folding door of the first embodiment is completely closed, and the two doors 1 and 2 are flat. At this time, the bellows 6 installed between the side surfaces of the door has a very narrow gap between the folded and bent portions, but before this state is reached, the fingers placed here are removed as described above. ing. If you don't want the light in the next room to leak when the folding door is closed, you can set the length of the bellows to be approximately the same as the height of the door.

In the second embodiment of the present invention, two folding doors 1, 2 are connected by a hinge 3, and a spring is attached as a shield between the side surfaces 4, 5 of the two folding doors 1, 2. A biased protruding piece 9 is installed. The protruding piece 9 is installed on the side surface 4 of the one door 1.

As shown in FIG. 8, the projecting piece 9 is composed of a main body 10, a tongue portion 11, and a leaf spring 12.

The main body 10 has a long box shape. A vertical notch 13 is formed at the center of one side of the body 10, and flanges 14 and 14 are formed on both sides of the notch 13. A plurality of retainers 15 ... Are formed on both outer sides of the main body.

The tongue portion 11 has a T-shaped cross section, and the width of the upper side thereof is slightly narrower than the lateral width of the hollow portion of the main body so that the tongue portion 11 can easily slide in the hollow portion.

The leaf spring 12 has a wavy shape, a length that is substantially the same as the body 10, and a width that is slightly smaller than the hollow portion of the body.

In the protruding piece 9, the central piece of the tongue portion 11 projects into the hollow portion of the main body 10 from the notch 13 of the main body, and the tongue portion 11 is inserted so that the upper side is inside the hollow portion. Then, the leaf spring 12 is inserted between the upper side of the tongue portion 11 and the bottom surface of the main body. The leaf spring 12 biases the tongue portion 11 so as to push it constantly.

The protrusion piece 9 assembled in this manner is attached to the door by engraving a rectangular groove substantially the same as the main body on the side surface 4 of one door 1 and embedding the main body 10 in the groove. It is a thing. Then, since the retainers 15 are formed on both sides of the main body 10, they cannot be easily removed after the main body is embedded.

FIGS. 6 and 7 show a state in which the folding door of the second embodiment is being closed, and the two doors 1 and 2 are at an angle of about 90 degrees. At this time, the tongue portion 11 of the protruding piece 9 installed on the side surface 4 of the one door 1 is projected to the foremost portion by the leaf spring 12, and the distance between the tip of the tongue portion and the side surface 5 of the other door 2 becomes narrow. There is. During this period, the fingers are inserted, but in this state, the tongue 11 touches the tongue 11 even if the finger is placed between them, and therefore the person senses danger and pulls out the finger from here. Like

FIG. 5 shows a state in which the folding door of the second embodiment is completely closed, and the two doors 1 and 2 are flat. At this time, since the tip of the tongue portion 11 is in contact with the side surface 5 of the one door 2, when used as a partition, the light is not blocked by the tongue portion and leaks to the adjacent room.
