BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door guide device that can be used for supporting and guiding sliding doors in stationary furniture such as clothes dance and built-in furniture such as a closet.

[0002]

2. Description of the Related Art Generally, in a sliding door guide device for furniture or the like, it is necessary to secure a sliding door opening / closing path on an extension line of the sliding door at the closed position. Therefore, when two sliding doors are used next to each other, the positions of both sliding doors have to be shifted back and forth, so that there is a step between the closed sliding doors. Further, even when one sliding door is used, since the fixed wall is arranged inside the sliding door opening / closing path, there is a step between the closed sliding door and the fixed wall.

Recently, there has been considered a sliding door structure which does not require such steps. That is, as shown in FIG. 1, as a special sliding door structure in which two closed sliding doors or a sliding door and a fixed wall form a flat surface, a telescopic rail unit that supports the sliding door 1 so as to be movable in the opening / closing direction. Two
The end of the sliding door opposite to the opening direction is pivotally mounted horizontally about the vertical support 3 and is supported by the rocking limit stopper mechanism 4 so as to be rockable only within a certain range. A sliding door guide device has been conceived, which is mounted on the frame 5 and is provided with rocking frame position holding means for stabilizing the frame 5 at both ends of the rocking range.

In such a sliding door guide device, when the sliding door 1 at the closing limit position A is opened, the sliding door 1 is first swung together with the swing frame 5 so as to be pulled out toward the front centering on the vertical support shaft 3. Then, the sliding door 1 can be opened horizontally relative to the swing frame 5 by utilizing the extension of the telescopic rail unit 2.

[0005]

In the sliding door guide device as described above, when another sliding door (or fixed wall) 6 is arranged adjacent to the opening direction side of the sliding door 1 in the closed limit position A, The sliding door (or fixed wall) 6 can be arranged so as to be flush with the sliding door 1 in the closing limit position A (of course,
The sliding door 6 is also supported by the same guide device as the sliding door 1), but when the sliding door 1 is opened as described above, the sliding door 1 overlaps the front surface of the other sliding door (or fixed wall) 6. The sliding door 1 (or the fixed wall) 6 is not completely closed to the closing limit position A.
When pushed to the side or when pushed, the telescopic rail unit 2 comes into contact with the surface of the sliding door (or fixed wall) 6,
The surface of this sliding door (or fixed wall) 6 may be damaged. Further, when the sliding door 1 is closed and a pressing force acts on the sliding door (or fixed wall) 6 side, the rail unit 2 in the middle of contraction slides on the surface of the sliding door (or fixed wall) 6 and is similarly damaged. Will be lost.

Further, the sliding door 1 is swung forward together with the swing frame 5, and then the sliding door 1 is opened. However, forgetting to swing the sliding door 1 forward, the sliding door 1 is swiftly opened. If it is attempted to do so, the end surface of the sliding door 1 collides with the end surface of the sliding door (or the fixed wall) 6 and both end surfaces are damaged.

And the pin 2 protruding upward from the lower plate 14b of the fixed frame 14 facing the lower side of the free end of the swing frame 5.
3, and both end extending portions 24a and 24b to the both pins 2
Torsion coil spring 24 loosely fitted and locked to 2, 23
It consists of

Reference numeral 25 denotes a lock mechanism, which is an L-shaped lever 27 having an intermediate bent portion pivotally attached to the upper surface of the free end of the swing frame 5 by a vertical support shaft 26 and downward from the upper plate 14a of the fixed frame 14. One side 2 of the L-shaped lever 27 protrudingly provided
7a, a first stopper 28, and the L-shaped lever 27 is projected downward from the upper plate 14a of the fixed frame 14 at a position where the L-shaped rail 27 is sandwiched between the first stopper 28 and the first stopper 28. A second stopper 29 acting on the first engaging portion 27b formed at the inner end of the L-shaped lever 27, and a torsion coil spring 30 for urging the L-shaped lever 27 to rotate toward the second stopper 29. And an operating tool 31 which is axially supported on the rear surface side of the sliding door 1 and which can be fitted into and removed from the second engaging portion 27c formed at the outer end of the L-shaped lever 27. The operation tool 31 is composed of a vertical shaft roller, and the vertical shaft roller is a vertical support shaft for a pair of upper and lower bearings 11b formed on the mounting plate 11a of the locking piece 11 fixed to the back surface of the sliding door 1. It is pivotally supported.

As shown in FIGS. 2 to 5, the swing frame 5
Is at the inner swing limit position a, that is, when the stop plate 16a of the stopper mechanism 4 is in contact with the supporting horizontal shaft roller 15, the relative positions of the two pins 22 and 23 of the swing frame position holding means 21. As shown in FIG. 4, the positional relationship is such that the pin 22 on the rocking frame 5 side is located inward with respect to the pin 23 on the fixed frame 14 side, so that these pins 22 and 23 are separated from each other. The biasing force of the torsion coil spring 24 that acts so as to
The rocking frame 5 is biased inward so that the stopper plate 16a is pressed against the roller 15, so that the rocking frame 5 is pressed.
Is stably held at the inner swing limit position a.

When the swing frame 5 is in the swing limit position a on the inner side as described above, the sliding door 1 is also in the closing limit position A. At this time, the operating tool 31 on the sliding door 1 side is shown in FIG.
As shown in FIG. 2, the L-shaped lever 27 is engaged with the second engaging portion 27c beyond the tip protruding portion 27d, and the first stopper 2
Reference numeral 8 indicates that the L-shaped lever 27 rotates in the direction of arrow 32 (counterclockwise) shown in FIG. It is blocking. Therefore, even if the sliding door 1 is immediately slid in the opening direction (the direction of arrow 33 in FIG. 2) from such a state, it cannot rotate counterclockwise as described above. The joint 27c prevents the sliding door 1 from opening via the operation tool 31.

As shown in FIG. 6, the sliding door 1 together with the swing frame 5 is swung outward around the vertical support shaft 3 (see FIG. 1), and the swing frame is in the swing limit position a on the inside. 5
When switching to the outer swing limit position b in which the supporting horizontal shaft roller 15 comes into contact with the stop plate 16b of the stopper mechanism 4, as shown in the drawing, the pin 22 on the fixed frame 14 side with respect to the pin 22 on the swing frame 5 side. Is located outside, the biasing force of the torsion coil spring 24, which acts to separate the pins 22 and 23 from each other, oscillates outward so that the stop plate 16b is pressed against the roller 15. Since the moving frame 5 is biased, the swing frame 5 is stably held at the outer swing limit position b.

When the biasing force of the torsion coil spring 24 on the swing frame 5 switches from inward to outward, the pin 23 on the fixed frame 14 side and the swing frame pivotally mounted vertical support shaft 3 (see FIG. 1) are used. It is when the pin 22 on the swing frame 5 side moves from the inner side to the outer side with respect to an imaginary line connecting (see).

When the swing frame 5 swings as described above, the first stopper 28 causes the one side 27 of the L-shaped lever 27.
so as to move relative to the L-shaped lever 27 along a.
One side 27a of the L-shaped lever 27 is formed. Then, as shown in FIG. 6, the first stopper 28 is disengaged from the one side 27a of the L-shaped lever 27 only when the rocking frame 5 reaches the outer rocking limit position b. The length of one side 27a of the lever 27 is set.

Therefore, when the swing frame 5 is at the intermediate position until it reaches the outer swing limit position b, the sliding door 1 cannot be slid with respect to the swing frame 5 in the opening direction indicated by the arrow 33. As described above, the operation tool 31 and the second engaging portion 27c of the L-shaped lever 27 prevent the operation. When the swing frame 5 reaches the outer swing limit position b, the first stopper 28 is disengaged from the one side 27a of the L-shaped lever 27 as described above, and the L-shaped lever 27 causes the spring 3 to move.
Since it can rotate in the direction of arrow 32 (counterclockwise) against the biasing force of 0, the sliding door 1 can be opened in the direction of arrow 33.

That is, when the sliding door 1 is opened, the operation tool 3
1, the L-shaped lever 27 moves in the direction of the arrow 32 against the biasing force of the spring 30, and gets over the tip projection 27d. Then, in this way, the operation tool 31 has the L-shaped lever 27.
7, the L-shaped lever 27 is rotated clockwise by the urging force of the spring 30 as shown in FIG. 7, and the first engaging portion 27b at the inner end thereof is the second stopper. 29 to prevent the swing frame 5 from swinging back inward. That is, the swing frame 5 is automatically fixed at the outer swing limit position b.

The opening movement of the sliding door 1 is carried out by the advancing movement of the intermediate movable rail 10 with respect to the swing frame side fixed rail 7 of the telescopic rail unit 2 and the advancing movement of the sliding door side movable rail 8 with respect to the intermediate movable rail 10. I, sliding door 1
Is supported in a cantilevered manner by the telescopic rail unit 2 extending from the swing frame 5. The sliding door 1 that opens in this manner is a rail that extends the front side of another sliding door (or a fixed wall) 6 that is adjacent to the sliding door 1 in the closing limit position A on the opening direction side as described above. The unit 2 moves without sliding contact with the other sliding door (or the fixed wall) 6. In the open state of the sliding door 1, as described above, the swing frame 5 is automatically fixed by the lock mechanism 25 at the swing limit position b on the outer side, so that the sliding door 1 is pushed in the direction of the arrow 34 shown in FIG. Even when pressure is applied, the sliding door 1 does not swing together with the swing frame 5 in the pressing force acting direction, and the telescopic rail unit 2 does not come into contact with the surface of the another sliding door (or fixed wall) 6. .

When the sliding door 1 is closed with respect to the swing frame 5, the operating tool 31 is engaged with the second stopper 29 and the first engaging portion 27b is engaged with the second stopper 29, as shown in FIG. The L-shaped lever 27 acts on the outer oblique side 27e of the tip protruding portion 27d of the L-shaped lever 27 in the open state and swings the L-shaped lever 27 counterclockwise against the biasing force of the spring 30. When the sliding door 1 has completely reached the closing limit position A after getting over the distal end protruding portion 27d, the operating tool 31 engages with the second engaging portion 27c of the L-shaped lever 27. As a result, the L-shaped lever 27 is in the unlocked state in which the first engaging portion 27b is disengaged from the second stopper 29, as shown by the phantom line in FIG.

When the sliding door 1 is completely closed to the closing limit position A as described above, the swinging frame 5 is allowed to swing inward from the outside swinging limit position b. Can be pushed inward to integrally swing the sliding door 1 and the swing frame 5 around the vertical support shaft 3 to return the swing frame 5 to the inner swing limit position a. . At this time sliding door 1
Is flush with another sliding door (or fixed wall) 6 provided adjacent to the sliding door 1 on the opening direction side. As described above, the swing frame 5 is held at the inner swing limit position a by the biasing force of the spring 24 of the swing frame position holding means 21.

In the above embodiment, the lock mechanism 25 is
Although the function of disabling the opening movement of the sliding door 1 is provided until the swing frame 5 reaches the outer swing limit position b, this function is not essential to the present invention and can be omitted.
