DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of assembling an interlocking folding door used for opening and closing a front opening of a storage space in furniture such as a clothes wardrobe and a closet.

[0002]

2. Description of the Related Art The interlocking folding door is shown in FIGS.
(A) As shown in the schematic diagram of (B), a plurality of door pairs a,
b, c, and the door pair a, b, c is a pair of doors d,
d ′ are connected by a folding hinge e so that they can be folded with their back surfaces facing each other,
Opposite ends of each two adjacent door pairs a and b, and b and c are connected by a common center hinge f so that the surfaces of the doors d 'and d can be folded in a state where they face each other. Outer door d in two door pairs a, c of
The center hinge f and the side hinge g are connected by a side hinge g such that the center hinge f and the side hinge g can be freely opened and closed.
(Not shown) engages both vertical and horizontal rollers (not shown) with upper and lower guide rails i and j attached to a top plate and a base plate of a door mounting body h such as furniture. By being guided so as to be able to run freely along the guide rails i and j, it is configured so that it can be opened and closed in an integrated manner.

Conventionally, a side hinge and a center hinge integrally formed with a hinge body also serving as a traveling body have been used for assembling the interlocking folding door. In addition, in the case of the interlocking folding door of the above type, since the hinge main body (traveling body) cannot be retrofitted to the guide rail i due to the structure,
With the hinge main body engaged with the guide rail i in advance, the guide rail i is fixed to the door mounting body h, and then the door is assembled.

[0004]

However, in the conventional interlocking folding door assembling method using the side hinge and the center hinge formed integrally with the hinge main body, the recess formed on the back surface of the hanging end of the door is not provided. After fitting the socket in place,
This is fixed to the door by screwing, but during that time, the door must be supported at a predetermined position, and the work is complicated and the workability is poor, so much labor and time are required. Not only does it take
The mounting position was likely to be out of order, and it was difficult to obtain the mounting accuracy of the door.

Further, the connection between the hanging side and the symmetrical end of two adjacent doors is performed in an open state in which both doors are folded. In this case, a gap between the two doors when closing is required.
Since it cannot be set larger than a certain size, it is not possible to use an embedded type hinge with a socket that can provide a large connection strength, and it must rely on an imposition type hinge with a small connection strength, and as a result There is also a problem that assembling large and heavy interlocking folding doors such as closet furniture is not suitable in terms of strength.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the related art, and allows a plurality of doors to be attached one by one by a one-touch operation, so that assembly can be simplified and speeded up. And an assembling method of the interlocking folding door.

[0007]

In order to achieve the above object, the present invention comprises a plurality of door pairs, wherein the doors of each door pair are pivotally connected to each other, and the doors of two adjacent door pairs are connected to each other. While being pivotally attached to a common center hinge, the outer doors of the door pairs at the left and right ends are pivotally attached to side hinges, and the center hinge and side hinge are attached to the upper and lower guide rails of the door mounting body. In the method of assembling an interlocking folding door that is engaged and guided so as to be able to run freely, a plurality of side hinges and a center hinge that can be inserted and connected with the traveling body and the hinge body, and
A pair of sockets and a plurality of folding hinges that can be connected by inserting a hinge body are prepared, and the upper guide rail is engaged with the upper guide rail while the upper running body of the side hinge and the center hinge is engaged with the door mounting body. The lower guide rail is fixed to the base plate of the door mounting body, and the lower traveling body of the side hinge and the center hinge is mounted on the top guide plate, while each door has its hanging side end. The side hinge and the upper and lower hinge bodies of the center hinge are fixed to the upper and lower parts of the unit via sockets, and the folding hinge sockets are provided at the upper and lower ends of the ends that are symmetrical with the hanging side. Are fixed, and the respective doors are one by one, and the upper and lower hinge bodies thereof are connected to the side-hinge and the upper and lower traveling bodies of the center hinge. A method of assembling an interlocking folding door, wherein two adjacent doors are connected and hung by inserting the hinge body into a pair of sockets fixed to the two doors so as to be foldably connected. Trying to provide.

[0008]

A plurality of side hinges and a center hinge formed so that the traveling body and the hinge body can be connected by insertion, and a plurality of folding hinges formed such that a pair of sockets and the hinge body can be connected by insertion. First, the traveling bodies of the two side hinges are engaged with the upper guide rail, and a required number of traveling bodies of the upper center hinge are engaged between the two traveling bodies. The guide rail is fixed to the top plate of the door mounting body such as a cabinet by screws or the like.

On the other hand, the lower guide rail is fixed to the base plate of the door mounting body by screws or the like, and then the traveling body at the two lower side hinges and the traveling body between the two traveling bodies.
The traveling bodies at the required plurality of lower center hinges are respectively placed.

[0010] Of the plurality of doors, sockets are fitted and screwed into recesses previously formed in the upper and lower portions of the rear surface of the hanging side end of the doors at the left and right ends. Each hinge body of the side hinge is fixed. On the other hand, each door located between the two doors is located in a recess previously formed in the upper and lower portions of the back surface of the hanging side end portion, and a socket is fitted and screwed, Thus, the hinge bodies of the center hinge are fixed respectively. Further, the sockets of the folding hinges are screwed into the recesses which are located on the back surface of the ends which are symmetrical with the hanging side of the doors and which are previously recessed at the upper and lower portions. To fix.

[0011] Next, the door is held, and the upper hinge body and the lower hinge body are inserted into the upper running body and the lower running body engaged with the upper guide rail, respectively, and are connected to each other. To suspend the door.
In addition, the doors can be suspended one by one and in any order.

When all the doors are attached to the upper and lower guide rails in this way, the two adjacent doors are fixed to the two doors in advance in a folded open state with their backs facing each other. By inserting and connecting the hinge main body to the pair of sockets, the plurality of doors can be integrally assembled to the attachment body so as to be able to open and close in an integrated manner.
