DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interlocking mechanism for a sliding door, and more particularly to a side door having a side door disposed on both sides of an opening and closing opening and a center door disposed at the center of the side door. The present invention relates to an improvement of an interlocking mechanism of a slide door, which moves the door with a double amount of movement with respect to a center door.

[0002]

2. Description of the Related Art Conventionally, a sliding door used as a door for opening and closing an opening has been used in combination of a plurality of doors.

For example, considering a case where a plurality of doors are used in combination at the same opening / closing opening, two sliding doors are used.
Or a structure in which three pieces are combined is general.

In the case of a combination slide door of such a pulling type, when a plurality of doors are used in combination, the opening and closing opening can be opened and closed widely by increasing the number of doors. There has been a problem that the moving distance of the operating person is increased and the operability is deteriorated.

[0005] The applicant has studied diligently and found that when one of the sliding doors is opened and closed, the other doors are also moved in conjunction with each other so that the moving distance of the operator can be reduced. Paying attention, in particular, the width of the side doors arranged on both sides of the opening / closing opening is configured to be half of the width of the center door arranged between these two side doors.
We have developed and applied for an interlocking mechanism that can move at double speed and can move at double speed (Japanese Patent Application Laid-Open No. H10-121848).

That is, the interlocking mechanism is configured as shown in FIGS. 7 and 8, for example. FIG. 7 is a plan view of the slide door provided with the interlocking mechanism, and FIG. 8 is a front view of the slide door provided with the interlocking mechanism.

[0007] The sliding door 030 is composed of a combination of three sheets, and is a double-sided door 032 disposed on both sides of the opening and closing opening.
a, 032b and a center door 031 arranged at the center thereof
The side doors 032a and 032b and the center door 031 are supported by an upper guide of an opening / closing opening (not shown) via a guide roller.

This interlocking mechanism is employed in the sliding door 030, and is composed of a combination of a plurality of links, and is attached to mounting members 035a, 035b fixed to the rear surface ends of the rear surfaces 032a, 032b of the side doors. First links 036a and 036b having one ends pivotally connected thereto,
A second link 039 is pivotally connected to the other ends of the first links 036a and 036b via a shaft member 037 protruding from the back surface of the center door 031.

According to the interlocking mechanism of the sliding door 030 thus configured, one end surface of one side door 032a of the sliding door 030 is brought into contact with the side wall of the opening / closing opening.
When one side door 032b is opened and moved by the distance L in the direction of the arrow in FIG.
In conjunction with the movement of 2b, it moves by L / 2 from the original position.

At this time, the first link 039 is rotated clockwise by opening one side door 032b, but the other side door 032a cannot move.
The shaft member 037 of the first link 039, that is, the center door 031
It moves L / 2 itself.

Then, both end surfaces 031 of the center door 031
The movement of the side door 032b and the center door 031 is stopped when a and 031b come into contact with the mounting members 035a and 035b, respectively.

By adopting such an interlocking mechanism for the slide door, each door can be interlocked when one of the slide doors is opened and closed, so that the moving distance of the operator can be reduced. It has become possible.

The applicant has further developed the above-mentioned interlocking mechanism, which is composed of a combination of a single link, and which is composed of a combination of a plurality of links. It is not necessary to consider the balance between the vertical mounting position of the link with respect to the center of gravity of the sliding door and the sliding resistance of the upper guide, and pay attention to the point that the sliding door can be opened and closed smoothly. The interlocking mechanism of the sliding door of the invention has been completed.

[0014]

That is, according to the present invention, an interlocking mechanism of a slide door in which a side door is moved with a double amount of movement with respect to a center door is provided. An object of the present invention is to provide an interlocking mechanism of a sliding door that can be opened and closed in cooperation with each other in a stable state regardless of an operation position.

[0015]

[0016]

Means for Solving the Problems To solve the above problems,
Therefore, the sliding door interlocking mechanism of the present invention has a side door which is supported by the opening and closing port so as to be slidable and arranged on both sides of the opening and closing section, and a center door which is disposed at the center of the side door. And a slide interlocking mechanism that moves with a double amount of movement with respect to the side door, wherein the interlocking mechanism includes two sets of intersecting links in which intermediate portions intersecting each other are pivotally supported. Each end is pivotally connected to each other, and at least each of the intersecting intermediate portions of the links is slidably engaged with a lateral guide provided on the center door. It is characterized in that two portions at each outer end are slidably engaged with vertical guides provided on the side doors. According to this feature, at least two intersecting intermediate portions of the links are slidably engaged with the lateral guides provided on the center door, and two portions at each outer end of the two sets of intersecting links connected to each other. Are slidably engaged with the vertical guides provided on both side doors, so that when the operator opens and closes the door, at least each of the upper and lower engagement portions is used as a reference for each intermediate portion where the links intersect. Since the door slides evenly in the vertical direction, the door can be opened and closed smoothly without being affected by the position where the operating force is applied by the operator when the door is opened and closed.

It is preferable that the sliding door interlocking mechanism of the present invention is configured so that a portion slidably engaged with the guide is guided in a vertical or horizontal direction by a guide roller. With this configuration, even if the direction of the load acting on the guide changes when the door is opened and closed, the guide roller is used, so that the guide can be moved up and down smoothly.

The sliding door interlocking mechanism of the present invention is preferably such that the guide is embedded flush with the back surface of the center door or both side doors. With this configuration, even if the slide door is provided with an interlocking mechanism by a link mechanism, the guide rollers that are supported by the connecting portion or the pivot portion and the guide that engages with each door are flush with the back surface of each door. , The sliding doors supported so as to be able to slide in a sliding manner can be arranged close to each other.
