Description

[Detailed description of the invention] This invention relates to a folding door device in which a folding door that can be folded and extended is attached to a rail so that it can be opened and closed.In detail, the invention has a simplified structure in which the folding door is brought into contact with a doorstop in an extended state. related to technology.

In general, for bi-folding doors, 2
It is formed by connecting two doors with hinges so that they can be folded and expanded. For reasons of appearance, when the folding door is in its extended state, one side of the door and one side of the hinge are made substantially flush with each other. This folding door is attached to the rail so that it can be opened and closed, but in order to prevent it from moving further to one side when the folding door is extended and the opening is closed, a door stop is attached to the rail so that it extends in the longitudinal direction of the rail. will be provided. However, if one side of the door and hinge is in contact with the door stop when the folding door is extended, then when the folding door is opened or closed, when the two doors rotate, the edge of the door will come into contact with the door stop, causing the door to open and close. cause trouble. For this reason, the dimensional relationship between the door or hinge and the door stop is set so that when the folding door is in the extended state, there is a gap between one side of the door or hinge and the door stop in the left and right direction for approximately the entire length. A part of the door stop has a protruding contact portion that comes into contact with the doorstop. Conventionally, a special member has been attached to form this abutted portion, which has the disadvantage of requiring an extra member.

The present invention has been developed in view of these shortcomings, and its purpose is to effectively utilize a part of the latch that holds the folding door in an extended state to form a contact area, which is different from the conventional method. To provide a folding door device whose structure can be simplified without requiring any extra members.

In other words, the present invention pivots the two doors 1, 1 so that they can be folded and expanded by a hinge 2 that is arranged between the two doors 1, 1 so as to span the vertical direction of the doors 1, 1. One side of door 1, 1 and hinge 2
The folding door 11 is configured such that the folding door 11 is substantially flush with one side of the rail 8, and both ends of the folding door 11 in the left and right direction are attached to the rail 8, and the runner 3 at at least one end of the folding door 11 is attached to the rail of the rail 8. A latch box 5 is attached to the longitudinal end of the hinge 2 so as to protrude from one side of the hinge 2, and a latch 7 that moves in and out of the rail groove 4 in conjunction with an operating tool 6 is provided. A part of the latch box 5 protruding from one side of the hinge 2 is used as an abutted part 10 that comes into contact with a door stop 9 provided in the longitudinal direction of the rail 8.
This invention relates to a folding door device in which mohair 23 is provided over the entire length of the doorstop 9, and by configuring it in this way, the above object can be achieved.

Embodiments of the present invention will be described in detail below with reference to the drawings.

11 is a folding door, two doors 1,
1 is pivotally connected to the door 1 by a hinge 2 extending in the vertical direction of the doors 1, 1 so as to be foldable and extensible. This folding door 11 is configured such that one side of the doors 1 and one side of the hinge 2 are substantially flush with each other. Runners 3 are provided at the upper and lower ends of both left and right ends of the folding door 11, respectively, and the runners 3 are inserted into the rail grooves 4 of the upper and lower rails 8, so that the folding door 11 can be opened and closed in the opening between the upper and lower rails 8. It is installed on. In this embodiment, the runner 3 on one end of the left and right is fixed so that it cannot run, and the runner 3 on the other side is made to be able to run freely, and the runner 3 that can run freely is fixed to the rail groove 3. By running the door 11, the folding door 11 can be folded and opened, and can be closed when it is extended. Although such a folding door 11 is used in a bathroom or the like, it can also be used in other places.

The pivot structure between the hinge 2 and the doors 1, 1 is shown in Figure 6.
As shown in Fig. 7, the aluminum receiving semi-cylindrical shaft part 13 is inserted into the receiving half-cylindrical shaft part 12 of the hinge 2 made of aluminum from the longitudinal direction of the door 1, and is attached to the receiving half-cylindrical shaft part 13 of the aluminum hinge. It has been inserted. Such a pivot structure can be modified in various ways.

A latch box 5 made of synthetic resin is attached to the upper end of the hinge 2 in the longitudinal direction. A latch 7 is provided within the latch box 5 so as to be able to move upwardly and downwardly. The latch 7 is urged upwardly by a spring 14. A grip portion 15 is provided at the upper and lower intermediate portions of the hinge 2, and above the grip portion 15, an operating tool 6 is configured to be operable to change the vertical position within the range of the elongated hole 17. The operating tool 6 and the latch 7 are connected by a metal connecting pipe 18. By putting a finger on the grip part 15 and pushing down the operating tool 6 with the thumb, the latch 7 is pulled into the latch box 5 against the spring 14, so that the folding door 11 can be opened and closed. In the closed state, when the finger is removed from the operating tool 6, the latch 7 is pushed into the rail groove 4 of the rail 8 by the spring 14, preventing the folding door from being opened unexpectedly when the folding door 11 is in the extended state. It can be done so that there are no problems.

A lock operating tool 19 is also provided below the grip portion 15 so as to be able to freely change its vertical position. Lock operation tool 1
9 can be maintained in its vertical operation position by a spring 20. A lower lock body 22 is connected to the lock operation tool 19 by a connecting rod 21, and by operating the lock operation tool 19, the lower lock body 22 is dropped into the rail groove 4 of the lower rail 8 to open the folding door. 11 is made so that the outside surface cannot be seen and cannot be opened. That is, the lock operating tool 19 is provided on one side of the folding door 11 on the inside (the side on the indoor side of the bathroom).

As mentioned above, the latch box 5 is attached to the hinge 2 so that a portion protrudes from one side of the hinge 2 which is substantially flush with the doors 1 (the one side that will be the indoor side when installed in a bathroom). . A portion of the latch box 5 that protrudes from one side of the hinge 2 serves as an abutted portion 10 that abuts against a doorstop 9 provided on the rail 8 over substantially its entire length. As shown in FIG. 3, mohair 23 is pasted on the door stop 9 to prevent damage to the latch box 5 made of synthetic resin.
Moreover, it is designed to prevent collision noise from occurring.

In summary, the present invention is a door stop in which a latch box is attached to the longitudinal end of the hinge so as to protrude from one side of the hinge, and the part of the latch box that protrudes from one side of the hinge is provided along the longitudinal direction of the rail. Since the abutting part is made to abut, it is possible to form a abutting part that protrudes from one side of the door or hinge with the latch box that is naturally attached to provide the latch without having to attach an extra member as in the conventional case. It has the advantage of simplifying the door stop structure.Moreover, the latch can move in and out of the rail groove, and the inner surface of the latch box is the abutting part that comes into contact with the rail door stop. Since the mohair is provided over the entire length, there is an advantage that the inner surface of the latch box can be used as the contact area of the rail against the doorstop, and the mohair can be brought into airtight contact with the entire length of the folding door to maintain airtightness. .
