Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door structure in which a plurality of sliding doors are opened or closed independently or in conjunction with each other.

[0002]

2. Description of the Related Art As shown in FIGS. 7 and 8, the area of an opening 14 at the time of opening is made as large as possible, or
In order to make it easy to take out the articles stored in the center of the opening 14, the opening 14 such as a bookshelf or a storage room has three sliding doors 56,
It may be closed at 58,60.

At the right end of the left sliding door 56, a stopper 6 is provided.
2 are provided and move along a guide groove 64 formed on the back side of the middle sliding door 58. A stopper 66 is also provided on the front side of the middle sliding door 58, and a guide groove 68 formed on the back side of the right sliding door 60.
Move along.

In the above configuration, as shown in FIG. 8, when the sliding doors 56, 58, and 60 are opened (three sheets are overlapped) and the sliding door 60 is pulled rightward, as shown in FIG. The left end 68A of the guide groove 68 hits the stopper 66, and the sliding door 58 is moved until the left end 64A of the guide groove 64 hits the stopper 62, so that the opening 14 can be closed as shown in FIG. I have. As described above, by moving one sliding door in the closing direction or the opening direction, the other sliding door moves in conjunction with each other to open and close the opening 14.

However, for example, when the sliding door 60 is vigorously closed rightward and stopped, as shown in FIG. 11, the middle sliding door 58 moves rightward due to the inertial force, and accordingly, the sliding door 56 also moves rightward. Attracted in the direction. For this reason,
A gap is formed between the column 10 and the sliding door 56, and the opening 14 cannot be completely closed. Also, when the stopper closes vigorously, a collision sound is generated when the stopper collides with the end of the guide groove, which deteriorates the indoor environment.

[0006]

In view of the above facts, the present invention prevents another sliding door from moving due to inertial force even if the sliding door is closed vigorously, and reduces a collision sound when the sliding door is opened and closed. That is the task.

[0007]

According to the first aspect of the present invention, a plurality of sliding doors are moved independently or in conjunction with each other to open and close an opening.

A stopper is provided at the end of one of the overlapping sliding doors, and when the other sliding door moves in the closing direction, a holding means provided on the other sliding door hits the stopper and swings in the forward direction. Move. Thereby, the holding means holds the stopper, and one of the sliding doors is pulled in the closing direction. In addition, since the holding means holds the stopper while swinging and absorbing the collision energy, the collision sound at the time of opening and closing can be reduced. In addition, by forming the stopper and the holding means with nylon, the effect of reducing the collision noise is further enhanced.

Here, when the other sliding door is vigorously closed and stopped, one of the sliding doors further attempts to move in the closing direction due to the inertial force. However, the holding means does not swing and the stopper is still held. Sliding door also stops with the other sliding door.

According to the second aspect of the present invention, the holding means includes:
It consists of a holder pivotally supported by the other sliding door and urged to swing in the opposite direction by a spring.

The contact portion of the holder is located on the movement locus of the stopper, and when hitting the stopper, swings the holder in the forward direction. When the contact portion comes into contact with the stopper, the hook portion of the holder moves on the movement locus of the stopper, and holds the stopper between the contact portion and the stopper. Thereby, one sliding door and the other sliding door move integrally.

Further, the hook portion is bent and does not escape from the movement locus of the stopper unless a force greater than the inertia force in the closing direction of one of the sliding doors is received through the stopper. Therefore, even if the other sliding door is vigorously closed, one sliding door moves together with the other sliding door.

Further, if the other sliding door is forcibly pulled in the opening direction by hand, the hook is bent and escapes from the movement locus of the stopper, so that the other sliding door is overlapped with the one sliding door to open the opening. it can.

According to the third aspect of the present invention, when the contact portion comes into contact with the stopper and the stopper is held by the contact portion and the hook, the long groove formed in the stopper is engaged with the claw provided at the tip of the hook. Locked. Thereby, the holding state of the stopper can be reliably maintained.

According to the fourth aspect of the present invention, when the contact portion comes into contact with the stopper and the stopper is held by the contact portion and the hook, the magnetic material attached to the stopper is attracted to the magnet provided on the hook. Is done. Thereby, the holding state of the stopper can be reliably maintained.

[0016]

1 and 2, a sliding door structure according to the present invention is used for triple sliding doors 16, 18, and 20 for opening and closing an opening 14 between a pillar 10 and a pillar 12. FIG. One embodiment is shown. Although a holder and a stopper, which will be described later, have the same structure, different reference numerals are given for convenience of explaining the movement of the sliding door.

On the back surfaces of the sliding doors 18, 20, guide grooves 22, 24 extending in the lateral direction are formed. A block-shaped stopper 26 fixed to the surface of the sliding door 16 with a screw 25 is provided in the guide groove 22.
A block-like stopper 28 fixed to the surface of the sliding door 18 with a screw 25 is slidably inserted into 4.

On the side surfaces of the stoppers 26 and 28, elongated grooves 30 and 32 formed at acute angles extend in the vertical direction. These long grooves 30 and 32 are provided with holders 34 and 3 described later.
6 are locked to the claws 34B, 36B.

On the other hand, the left ends of the guide grooves 22 and 24 are recessed to form a storage section 40 in which the bracket 38 is stored. A mounting piece 42 projects up and down from the bracket 38, and the mounting piece 42 is fixed to the bottom surface of the storage section 40 with a screw 44.

The leg 38A of the bracket 38 has a shaft hole 4
6 are formed. The shaft hole 46 has a pin 48 projecting from the U-shaped holder 34 or 36 in a plan view.
Are supported so that the holders 34 and 36 can swing.

The pin 48 has a torsion spring 50
Is wound, and the holders 34 and 36 are urged to swing in the forward direction (clockwise). At this time, the plate portions 34C and 36C constituting the holders 34 and 36 hit the bottom surface of the storage unit 40, and the holders 34 and 36 are stopped.

Further, the contact portions 34 of the holders 34, 36
D and 36D are located on the movement trajectories of the stoppers 26 and 28 in the free state, respectively.
The hooks 34A, 36A rising from 36C are retracted from the movement locus of the stoppers 26, 28.

The hooks 34A, 36A are
6D, a holding portion for holding the stoppers 26 and 28 is formed. The hooks 34A and 36A are thin, and the claw 3 protruding toward the contact portions 34D and 36D is provided at the tip.
4B and 36B are provided. Then, the force greater than the inertia force of the sliding door (the force to open the sliding door by hand) is applied to the claws 34B and 36B.
, The hooks 34A, 36A are elastically deformed and further elastically deformed to escape from the movement locus of the stoppers 26, 28.

Next, the operation of the triple sliding door according to this embodiment will be described. As shown in FIG. 2, from the state where the sliding doors 16, 18, and 20 are opened (a state where three sliding doors are overlapped), the sliding door 20
3 is pulled toward the column 12 (rightward), as shown in FIG. 3, the contact portion 36 </ b> D of the holder 36 hits the stopper 28, and swings the holder 36 in the opposite direction (counterclockwise).
B enters the long groove 32 of the stopper 28, and holds the stopper 28 with the contact portion 36D and the hook portion 36A. Thereby, the sliding door 18 and the sliding door 20 move integrally.

When the sliding door 20 is further pulled from this state, the right end face of the sliding door 20 hits the pillar 12 and stops as shown in FIG. At this time, the stopper 26 is
4, the width of the sliding door 18 is determined so that the claw 34 </ b> B is engaged with the long groove 30. As a result, the stopper 28 is held by the holder 36, and the stopper 26 is held by the holder 34.
6, 18, and 20 form a series and close the opening 14.

Assuming that the sliding door 20 is vigorously closed rightward until it hits the pillar 12, the middle sliding door 18 moves rightward due to inertial force as shown in FIG. It is drawn to the right.

However, since the stoppers 26, 28 are held by the holders 34, 36 from both sides, the hooks 36A are slightly bent, and a gap may be instantaneously formed between the sliding door 16 and the pillar 10. However, it does not come off.
Therefore, the opening 14 is formed by the three sliding doors 16, 18, and 20.
Can be completely closed.

Further, in this embodiment, a claw is provided to lock the stopper. However, as shown in FIG.
A magnet plate 52 may be provided inside A, 36A, and a sheet metal 54 may be attached to the stoppers 26, 28, and the stoppers 26, 28 may be locked by magnetic force.

In this embodiment, three sliding doors are described. However, four or five sliding doors may be used, and the present invention can be used when there are a plurality of sliding doors. The stopper and the holder are made of 66 nylon, and are designed so that a collision sound is not generated when they collide with each other.

[0030]

According to the present invention, the other sliding doors do not move due to the inertial force even if the sliding door is vigorously closed. Therefore, there is no gap between the sliding door and the pillar. Further, it is possible to reduce the collision sound when the sliding door is opened and closed.
