DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interlocking folding door used for opening and closing a front opening of a storage space in furniture such as a clothes wardrobe or a closet, and is capable of running on a guide rail. The present invention relates to a detachable stopper suitable for temporarily stopping a mounted traveling body for mounting a door.

[0002]

2. Description of the Related Art As shown in a schematic front view of FIG. 7, an interlocking folding door includes a plurality of door pairs a, b, and c. The doors d and e are pivotally connected to each other by a folding hinge f # or the like so that the upper and lower ends of each of the doors e and d in the two adjacent door pairs a, b, and b, c are connected to each other. , Which are pivotally attached to the common center traveling body g so as to be freely foldable, and are located at the outer upper ends and the outer lower ends of the outer doors d and e of the left and right door pairs a and c. Are pivotally attached to the side traveling bodies h so as to be freely foldable.

Further, the traveling bodies g and h are located at a front opening j in a door mounting body i such as a cabinet.
The upper and lower guide rails k, k provided side by side along the upper and lower opening edges are engaged so as to be able to run freely, whereby a plurality of door pairs a, b, c are integrally linked, The front opening j can be opened and closed.

By the way, in such an interlocking folding door, each pair of doors a, b, c is previously connected to each of the traveling bodies g, h.
In this state, the traveling bodies g and h are engaged with the guide rail k so as to be able to travel freely, so that the door pair a, b and c can be mounted. However, this is practically impossible when the doors d and e are large and heavy. For this reason, the traveling bodies g and h are previously engaged with the guide rail k, and in this state, the doors d and e of the door pairs a, b and c are directly pivoted to the traveling bodies g and h. The doors a, b, and c are attached by attaching the hinges (not shown) to the doors d and e, and attaching the hinges to the traveling bodies g and h. Like that.

[0005] However, the above-mentioned door mounting means is very troublesome, requires a lot of trouble and time, it is not easy to adjust the mounting position, and there is a danger in the work. An attachment mechanism that connects a body and a hinge by a sliding operation has already been proposed.

In the above-mentioned slide type mounting mechanism, the roller unit of the traveling body and the mounting plate of the hinge on the doors d and e are slid with respect to the length direction of the guide rail. The sliding operation causes the lever to reverse against the urging force of the spring, and further, when the mounting plate is inserted into the roller unit to a predetermined position, at the same time, the lever is The roller is rotated backward by the force, whereby the roller unit is engaged with the engagement concave portion provided in the roller unit, so that each door pair is attached to each traveling body.

[0007] Therefore, when the above-mentioned slide type mounting mechanism is used, the mounting and dismounting of the door pair can be performed easily and quickly as compared with the conventional door pair mounting means. By sliding the hinge in the length direction of the guide rail with respect to the engaged traveling body, the hinge is attached to the traveling body, so that the traveling body unwillingly moves along the guide rail. A stopper for the traveling body needs to be installed on the guide rail so as to be detachable so that the traveling body does not move.

For this reason, a detachable stopper as shown in FIG. 8 has already been proposed for a guide rail in an interlocking folding door. The stopper 1 is composed of a member m for a traveling body (not shown) having a substantially inverted dish shape in cross section, a plate-shaped fixing member n, and a fixing screw o, as shown in the same figure. As described above, the member m and the fixing member n
Are superimposed one on top of the other at the opening rising edges p, p of the guide rail k, and in this state, the two members are fixed with the fixing screws
, And is mounted on the guide rail k so as to be detachable as necessary, so that the stopper function for the traveling body is exerted in a timely manner.

[0009]

However, in the case of the above-mentioned conventional stopper 1, it takes time and effort to attach and detach to and from the guide rail, and it is necessary to engage the guide rail so that it can run freely. If the traveling body of the vehicle hits vigorously, it may come off, and the fixing member n can be formed only to a certain thickness due to the problem of strength. There is a problem that mounting becomes impossible, and furthermore, since at least three parts are required, the manufacturing cost is high.

In view of the above-mentioned problems of the prior art, the present invention preliminarily attaches a traveling body to a guide rail so that the traveling body can travel freely, and in this state, as described above, applies to the traveling body. In order to secure the stationary state of the traveling body when installing and removing the door pair, a stopper that is fixed to the guide rail so that it can be easily attached to and detached from the guide rail easily and quickly. In addition, by effectively utilizing the mounting screws used for mounting the guide rails to the door mounting body such as a cabinet, the traveling body can be securely fixed without disengagement or moving. The goal is to offer something cheap.

[0011]

According to the present invention, in order to achieve the above-mentioned object, the stopper body is formed in a substantially rectangular parallelepiped shape, and its longitudinal dimension is set along the guide rail of the door pair along the longitudinal direction. The width is larger than the width of the opening that has been opened and is set to be substantially equal to the width in the guide rail,
The dimension in the short direction is set to a length that allows the stopper body to be inserted into and removed from the guide rail, and the height dimension is set to be approximately equal to the dimension from the back surface of the top wall of the guide rail to the rising edge of the opening. Further, at both ends in the longitudinal direction, a rotation stopper plate provided with an outward spring property is extended so as to be oriented in the same direction in the circumferential direction. Along with a knob formed to be rotatable within the opening of the guide rail so as to be freely rotatable.

[0012]

The side traveling body and the center traveling body are previously mounted on both upper and lower guide rails of the door mounting body so as to be freely movable. On the other hand, hinges are fixed to the upper end and the lower end of the hanging base of both doors of each door pair by embedding and fixing sockets on the inner surfaces thereof.

In such a state, the mounting plate of each hinge is pushed into the roller unit of each traveling body from one end in the longitudinal direction of the roller unit to one end in the longitudinal direction of the roller unit. Although the hinge is attached to the traveling body, each traveling body is mounted so as to be able to travel on the guide rail, so the stopper according to the present invention is attached to the guide rail as follows. Thus, the stopped state of the traveling body is secured.

Therefore, first, hold the knob, and move the stopper body so that its short direction is immediately below the opening of the guide rail.
Insert it into the guide rail while aligning it so that it is parallel to this. Next, when the stopper body is pivoted about a predetermined axis about its axis by the knob, the rotation stopper plates extending at both ends in the longitudinal direction of the stopper body are moved forward and backward of the guide rail. Abuts on the inner surface of each side wall, but when further rotated in the same direction, the rotation stopper plate is elastically deformed inward against its spring property, whereby the stopper body is rotated by 90 °. Position, that is, the elongate direction is rotated to a position perpendicular to the length direction of the guide rail and stopped.

In this state, the lower surface of the stopper body is
The stopper body is placed on a pair of opening rising edges of the guide rail, and the upper surface of the stopper body abuts or approaches the top wall of the guide rail, and the rotation stopper plate is provided on the inner surface of each side wall of the guide rail by its spring property. By pressing, the stopper body is held at the position described above. From this state, if the stopper is pressed and slid along the length direction of the guide rail, the stopper body comes into contact with the head of the mounting screw of the guide rail with respect to the door-to-mounting body. The stopper is located at a predetermined position in the guide rail, and is held in a fixed state that prevents further pushing, and the traveling body is held at a predetermined position on the guide rail by abutting the traveling body against the stopper. You will get.

Therefore, with respect to the stationary body,
The hinge attached to the door can be quickly, reliably and securely mounted by the sliding operation. Further, when the operation using the stopper is completed, the user can easily remove the stopper from the guide rail simply by holding the knob and rotating by 90 ° from the above-described mounting position. If it is attached to the position as described above, it can be used for attaching another hinge to another traveling body.
