Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door interlocking mechanism.

[0002]

2. Description of the Related Art As a triple-type sliding door interlocking mechanism
The one described in JP-A-196222 is known. This interlocking mechanism is provided with gear rollers that rotate around the vertical axis at the front end and the rear end of the upper end surface of the sliding door located in the middle, and these gear rollers are connected by an endless belt, and each of the sliding doors located on both sides. Is fixed to the endless belt via a fixing tool.

[0003]

When this interlocking mechanism is applied to a double sliding door structure, it is conceivable to configure it as shown in FIG. That is, gear rollers 11 and 12 that rotate around the vertical axis are provided at the front and rear ends of the upper end surface of one sliding door A1, and these gear rollers are connected by an endless belt 13, while the other sliding door A2 is fixed. It is fixed to the endless belt 13 via 14. Then, the endless belt 13 is fixed to the upper frame at a point (indicated by the apex of a triangular mark) substantially opposite to the fastening point.

In such a structure, when the sliding door A2 is moved to the right in the figure from the closed state shown in FIG. 1A, the endless belt 13 rotates counterclockwise in the figure, but one point of the endless belt 13 Since the endless belt 13 is fixed to the upper frame, the sliding door A1 also moves in the same direction as the endless belt 13 rotates. If the moving distances of the sliding doors A1 and A2 at this time are L1 and L2, the relationship of L2 = L1 × 2 is always established. In this way, the door open state shown in FIG. 1C is obtained through the moving state shown in FIG. 1B.

The moving distance of the sliding door door by this sliding door interlocking mechanism is determined by the moving distance of the fixture 14, but the sliding door door A
Since gear rollers 11 and 12 are provided at the front and rear ends of the upper end surface of 1, and it is necessary to avoid interference with these gear rollers, the moving distance of the fixture 14 is greater than the width dimension W1 of the sliding door A1. It has to be quite short. And also the point where the endless belt 13 is fixed to the upper frame,
Depending on the position of the fixture 14, the gear roller 1
In order to avoid interference with 1 and 12, it is necessary to set the distance between the open side gear roller 12 in the closed state and the close side gear roller 11 in the opened state, that is, within the range of the area B in FIG.

Considering the state when the sliding door is opened and closed, the vertical frame a11 on the closing side of the sliding door A1 and the vertical frame a22 on the opening side of the sliding door A2 overlap each other and form a door pocket when the door is closed. Most of the open side vertical frame a12 of the sliding door door A adjacent to C is exposed (FIG. 3 (a)), and when the door is opened, the sliding door doors A1 and A2 are both stored in the door pocket and are left behind. Does not occur (Fig. 3
(B)) is ideal.

However, in order to obtain the ideal closed state of FIG. 3 (a), as shown in FIG. 1 (a) and FIG.
Since the fixing position on the upper frame side to which the endless belt 13 is fixed is located on the opening side with respect to the vertical frame on the door pocket side, the sliding door A1 in the opened state as shown in FIGS. ，
The vertical frames a11 and a21 of A2 project from the upright C toward the opening (FIG. 3 (d)), causing a so-called residual residue, which is unattractive and makes it impossible to effectively use the opening width. turn into.

In order to obtain the ideal door open state of FIG. 3 (b), as shown in FIG. 4, the door pocket is formed to have a large size protruding toward the opening side, and the upper frame to which the endless belt 13 is fixed. The fixed position on the side may be provided in the door pocket, but when this is done, the closed state becomes as shown in FIG. 3A, and most of the vertical frame a12 of the sliding door A1 is hidden in the door pocket (see FIG. c)), which is very unattractive. In order to avoid this, the width dimension of the vertical frame a12 of the sliding door A1 may be formed to be large, but it will be out of the standard of mass production, resulting in an increase in cost.

In addition, while the belt-type interlocking mechanism as described above makes the sliding door door run smoothly, it is difficult to stop because the weight of a plurality of sliding door doors interlocking with each other makes it difficult to stop. When the opening / closing operation is performed, the action of the stopper may be insufficient to cause rebound, or the collision with the vertical frame D may damage the inner surface of the vertical frame.

[0010]

Therefore, the present invention solves the above-mentioned problems, and when the sliding door is closed, the vertical frames of the sliding doors are overlapped with each other and most of the vertical frames of the other sliding door adjacent to the door pocket are exposed. It is an object of the present invention to provide an interlocking mechanism having a novel configuration for preventing the sliding doors from being left in the door pocket when the doors are opened and the sliding doors are all stored.

It is another object of the present invention to provide an interlocking mechanism capable of exhibiting a cushioning function even when the sliding door is opened / closed vigorously and preventing damage and rebound due to a collision with a vertical frame. .

That is, according to the first aspect of the present invention, a pair of gear rollers are provided at the front and rear ends of the upper end surface of one of the sliding doors, the endless belt is wound between these gear rollers, and one point of the endless belt is set first. When the other sliding door is connected to the upper frame by the second connecting means while being connected to the other sliding door by the connecting means, the other point substantially opposite to the one point of the endless belt is moved and moved when the other sliding door is moved. In the sliding door interlocking mechanism in which the endless belt is revolvingly driven via the first connecting means, and thereby the one sliding door door is interlocked via the second connecting means, the second connecting means has an upper frame. A mounting member fixed to the endless belt, a slide member fixed to the endless belt, a slide unit that allows the slide member to slide relative to the mounting member, and a slide member that moves in a direction away from the mounting member. It is characterized by comprising a biasing means for biasing the.

When the sliding door is opened, the sliding member slides in the direction away from the mounting member. Therefore, the urging means for urging the sliding member in the opposite direction acts as a stopper to open the door vigorously. Even in this case, the sliding door does not collide with the opening vertical frame and damage the vertical frame. On the other hand, when the sliding door is closed, the urging means assists the movement of the sliding door in the closing direction, so that it is possible to obtain a good-looking completely closed state in which the vertical frames of the sliding door overlap each other.

According to a second aspect of the present invention, in the sliding door interlocking mechanism according to the first aspect, the mounting member has a fitting portion and a locking member fitting hole provided through the fitting portion, and the slide member has a long hole. The locking member is inserted into the locking member fitting hole and the long hole in a state where the slide member is loosely fitted to the fitting portion and fixed to the upper frame. The locking member fitting hole, the long hole and the locking member Are configured to cooperate with each other to form a slide means.

The state shown in FIG. 9D is obtained through the states in the middle of movement shown in FIGS. 9B and 9C. At this time, sliding doors A1 and A
2 and 2 are completely overlapped with each other, but the vertical frames a11 and A21 project toward the opening side more than the upright C and are not completely housed in the door pocket.

When the force for moving the sliding doors A1 and A2 in the opening direction further acts from this state, as described above, the sliding door A
Since the slide member 17 fixed to 1 is slidable with respect to the mounting member 16 fixed to the upper frame E, the two sliding door doors A1 and A2 move in the state of being completely overlapped to each other in the door pocket. It is completely stored, and the opened state of FIG. 9 (e) is obtained. In this state, the vertical stiles a11 and a21 do not project from the upright C to the opening side, and the sliding door doors A1 and A2 are completely stored in the door pocket. FIG. 3B is obtained. Although the mounting member 16 is illustrated as projecting from the upright C to the opening side in FIG. 9E, the mounting member 16 is fixed along the inner side surface of the upper frame E as described above. Therefore, it is not actually exposed in the opening and does not spoil the appearance.

The moving distance from FIG. 9 (d) to FIG. 9 (e) is equal to the moving distance in the elongated hole 17d of the locking member 18. That is, when the locking member 18 reaches the end of the elongated hole 17d (the right end in FIG. 7), the door open state of FIG. 8E is obtained.

According to this sliding door interlocking mechanism, an ideal closed state (see FIG. 3) is obtained by using the connecting means 15 in which the connecting position between the sliding door A1 and the endless belt 13 is slidable.
(A)) and the door open state (Fig. 3 (b)) can both be achieved, and even when the sliding door door is opened and closed vigorously by stepwise performing the stopper action, the vertical frame causes collision. It has the advantage that damage and bounce can be prevented. That is, when the state of FIG. 9 (d) is passed through the states of FIGS. 9 (a) to 9 (c), the fixing tool 14 engages with the gear roller 12 on the opening side, and further movement is impossible. Here, the stopper action in the first stage is exhibited.

The state change from FIG. 9 (d) to FIG. 9 (e) is performed by the slide member 17 moving relative to the mounting member 16 and entering into the mounting member 16. As described above with reference to FIG. 10 and as shown in FIG. 10, the coil spring 21c of the slide assisting member 21 gives resistance to the movement of the slide member 17 during this period, so that the second stage The stopper action is demonstrated.

The third stopper action is exhibited by the locking member 18 colliding with the end of the elongated hole 17d when the state shown in FIG. 9 (e) is obtained. The locking member 18 is the long hole 1

Can be prevented. Providing a cushioning material at the end of the long hole 17d is also an effective means.

On the contrary, when closing the sliding door doors A1 and A2 from the completely opened state of FIGS. 9 (e) and 10 (b), the front sliding door door A2 is moved leftward in the drawing. By the interlocking mechanism, the sliding door A1 on the back side is interlocked to move in the same direction, and the completely closed state of FIG. 9A is obtained. As described above, the slide assisting member 21 is provided with the coil spring 21d that acts as a biasing unit that moves and biases the slide member 17 in the direction away from the mounting member 16. Therefore, the sliding door A1 is driven by the biasing force of the coil spring. The movement in the closing direction of the

[0033]

According to the present invention, the sliding position of the sliding door and the endless belt can be slid in the belt-type sliding door interlocking mechanism, so that it is difficult to achieve the conventional ideal closed state (Fig. 3 ( a)) and an open state (FIG. 3B) can be obtained, and a sliding door structure with a good appearance can be provided.

Further, according to the sliding door interlocking mechanism of the present invention, when the sliding doors are in the overlapping state, the stopper action of the first step is exerted, and thereafter, the sliding doors are completely placed in the door pocket while being overlapped. The coil spring (biasing means) of the slide assist member exerts the second-stage stopper action until it is stored, and the third-stage stopper action is exhibited when it is completely stored in the door pocket. Thus, since the stepwise stopper action is achieved in this way, damage and rebound due to collision with the vertical frame can be prevented even when the sliding door door is opened and closed forcefully.
