Description

[Detailed description of the invention] This invention takes a two-panel folding door as one unit and connects and integrates multiple units to create a four-panel folding door,
This invention relates to a connecting device for a multi-panel folding door such as a six-panel type.

In general, a two-panel folding door has two vertically elongated door plates connected at their mutually adjacent ends so that they can be overlapped by a hinge, and the unconnected end of one door plate is pivoted at the corner position of the opening for installation. A guide member is attached to the non-connected end of the other door plate so that the guide member slides or rolls on a roller by fitting into guide rails arranged above and below the opening.

On the other hand, by connecting the two folding doors mentioned above, you can create a four-fold or six-fold door.
When converting to a multi-folding door such as a single-piece type, it is conceivable to connect the side edges of the door panels with hinges. However, in such a configuration, the pivot point for the guide rail of each door plate is located at a position away from the mounting surface with respect to the mutual rotation center of the connected door plates, and when the folding door is opened and closed, the above-mentioned connection The three rotation points of the parts interfere with each other and do not operate smoothly.
Another drawback is that it takes time and effort to attach the hinges. Therefore, a folding door with a dedicated structure for each number of door panels is usually used.

The present invention was developed to solve the above-mentioned drawbacks, and it allows a two-panel folding door to be used as a structural unit of a four-panel or six-panel multi-panel folding door without any problems, and the connection operation is extremely simple. It provides equipment.

Hereinafter, the present invention will be explained based on illustrated embodiments.

In the figure, reference numeral 1 denotes a folding door fitted between guide rails 3a and 3b disposed at the upper and lower edges of an opening 2, and is made up of four vertically elongated door plates 4 arranged in parallel in the horizontal direction. Each door plate 4 has square tubular upper and lower frames 5a, 5.
b and the left and right frames 6a, 6b are connected in a four-periphery frame shape,
A cushion material 7 is inserted on the front side of the mounting plate 8.
are stretched across a peripheral plate 9 having a substantially U-shaped cross section. Thus, the two adjacent door panels 4a, 4b and 4c, 4d are connected so that they can be folded over each other at three points on the upper, middle, and lower back sides of each other at the hinges 14. It consists of units A and B. Each of the guide rails 3a and 3b has a guide groove 10 open to the opposite side, and a pivot hole 1 is formed at the upper and lower opposite positions at the end of the door plate 4a.
1a is fitted into the guide groove 10, the bolt 12a and the square nut with claw 12
It is fixed by screwing with b. Furthermore, as shown in FIG. 7, at the end of the upper guide rail 3a on the door plate 4d side, a stopper 13 is provided with a buffer pin 13b which is biased toward the projecting side by a built-in spring 13a and is horizontally removable. It is fitted into the groove 10.

At vertically opposing positions on the side ends of the door plate 4a, there is an upper pivot pin 15 in the form of a round shaft, which is movable in the vertical direction via two mounting plates 14 each fixed to the upper and lower frames 5a and 5b. and a fixed bolt-shaped lower pivot pin 1
6 are attached so as to vertically penetrate through the upper and lower frames 5a and 5b, respectively. The upper pivot pin 15 is
The tip 15a is biased in the direction of upward protrusion by a coil spring 18 installed between a spring stop ring 17a fixed to the circumferential surface and the lower mounting plate 14, and a stop ring fixed to the lower circumferential surface. 17b
The limit position is set by the contact between the lower guide plate 14 and the bottom surface of the lower guide plate 14. Further, the lower pivot pin 16 is screwed into a nut 19 fixed to the upper mounting plate 14, and by adjusting the screwing position, the amount of downward protrusion of the tip 16a can be arbitrarily set. Thus, the tips 15a, 16a of both pivot pins 15, 16 are fitted into the pivot holes 11a of the bearing members 11 fixed to the guide rails 3a, 3b, respectively, so that the door plate 4a is pivoted to the guide rails 3a, 3b. be supported.

On the other hand, as shown in FIG.
An upper guide member 20 and a lower guide member 21 are respectively attached to vertically opposing positions on the adjacent end portions of. The upper guide member 20 has a bolt portion 2
A U-shaped plate 20b is attached to the top end of 0a so as to be rotatable in the circumferential direction, and this U-shaped plate 20b rotates the double-wheeled roller 20c.
It is fixed by screwing nuts 20d, 20d from both upper and lower sides to a bolt part 20 that passes through the upper frame 5a vertically, and the height can be adjusted by changing the screwing position. It is. The roller 20c of this upper guide member 20 is positioned within the guide groove 10 of the upper guide rail 3a. Similarly to the lower pivot pin 15, the lower guide member 21 connects the lower guide rail 3b to the lower end of a bolt portion 21a that passes through the lower frame 5b via two mounting plates 14 fixed to the lower frame 5b. A slide roller 21b is attached to fit into the guide groove 10. This lower guide member is designed to adjust the height of the slide roller 21b by changing the screwing position of the nut 19 fixed to the mounting plate 14 and the bolt member 21a.

In Fig. 3, especially Fig. 4, 22 is the door plate 4.
b, 4c are pivotally connected in the upper and lower positions, and there are through holes 22a and 4c bored at both ends thereof.
Both upper guide members 20, 20 inserted through 22b
The U-shaped plates 20b and 20b of the lower guide members 21 and the slide rollers 21b of the lower guide members 21, which are similarly inserted into the through holes 22a and 22b, are respectively installed. Note that these connecting plates 22 are connected to bolt-shaped upper and lower guide members 20, 2.
In order to rotatably fit into the guide member 1, the bolt part of each guide member is crushed to form a columnar shape, or the through hole of each connecting plate is fitted into the cylindrical part which is the non-bolt part and pivotably supported. do.

On the other hand, as shown in FIG. 7, an upper guide member 23 with a slide roller 23b attached to the upper end of the bolt part 23a is provided at a vertically opposing position at the side end of the door plate 4d, and as shown in FIG. , 4c and the lower guide member 21 having the same configuration as the lower guide member 21 in the upper and lower frames 5a, 5b in the same manner as described above.
is fixed. The slide roller 23b of the upper guide member 23 is in elastic contact with the stopper 13 when the folding door 1 is closed.

In the four-panel type folding door 1 having the above configuration, from the closed state in which all the door panels 4 are arranged in a plane as shown by the solid line in FIG. , upper and lower guide members 20,2
1 and 23 move along the guide rails 3a and 3b, and along with this movement, the door plate 4 is rotated so as to protrude forward at the joint by the hinge 14, and finally the door plate 4 moves toward the opening. It becomes an open state in which one corner of 2 is polymerized. Therefore, in the opening/closing operation of the folding door 1, the door plates 4 of the two-panel folding door unit A and unit B are not directly connected to each other, and the upper and lower guide members 2
Since the door plates 4b and 4c are connected through the connecting plate 22 at the connecting portions 0 and 21, the door plates 4b and 4c can rotate without interfering with each other at the connecting portion, and the opening and closing operations can be performed extremely smoothly.

Although the above embodiment shows a four-panel folding door 1, multiple-panel folding doors such as a six-panel, eight-panel, etc. A door can be configured. In addition, in the above embodiment, the folding door load is distributed to the upper guide members 20, 20 using rolling rollers and is borne by the upper guide rail 3a. However, the lower guide member is equipped with rolling rollers. The folding door load is reduced by using the lower guide rail 3b.
Alternatively, if the load is small, the load may be borne only by the upper and lower pivot pins 15 and 16. Therefore, the upper and lower guide rails 3a, 3b of each guide member
The structure of the engaging portion can be changed in various ways depending on the degree of load and the type of load. Furthermore, the connecting plate 22
The shape and the installation position for each guide member can also be changed in various ways.

As described above, the folding door connecting device according to the present invention uses two door panels that are pivoted so as to be superimposed as one unit, and by connecting these plurality of panels, four panels according to the installation opening can be used. Since it can be made into a multi-panel type folding door, such as a multi-panel type or six-panel type, there is no need to prepare a dedicated folding door for each different number of door panels, and parts manufacturing and assembly costs are significantly reduced. However, one unit of two-panel folding door is just 2
Can be used as a single folding door. In addition, the two-panel folding door unit is interconnected via a connecting plate installed between the guide members that fit into the upper and lower guide rails, and the door plates are not directly connected to each other by hinges, etc., so the folding door can be opened and closed. At times, adjacent door panels at the connecting portion rotate independently without interfering with each other, allowing for smooth opening and closing. Furthermore, the connection work is much easier than when the door plates are directly connected to each other by hinges or the like.
