DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door device for furniture and the like, and is provided along a guide groove such as a sliding door and a shutter door for opening and closing the front of various furniture such as a bookstore and a storage room, or a bellows type door for a partition. The present invention relates to a device for smoothly closing various sliding doors that are slid and guided.

[0002]

2. Description of the Related Art Generally, when two sliding doors are closed by abutting their leading end surfaces against each other, for example, see Japanese Patent Application Laid-Open No. 3-23992.
As described in the publication, a stopper fitting for regulating the closing position of the two sliding doors is used, but at the time of closing the door, a contact piece provided on the sliding door collides with the stopper fitting,
Inconveniences such as generation of impact noise and rebound of the sliding door from the closed position to the open side are likely to occur.

In the case of a type in which the sliding door is closed by contacting the end face of an opening of furniture or the like with a stopper, a stopper is not usually used. Tends to occur.

As a countermeasure for this, Japanese Patent Application Laid-Open No. 8-189
In Japanese Patent Publication No. 266, a sliding stud which is slidably and slidably fitted in a guide groove is protruded from a lower end of a front end surface of a shutter door, and is fitted between opposed inner walls of the guide groove in the guide groove. A stopper member having a barrier portion to be fitted and a resilient contact piece extending from the barrier portion along the guide groove is fixed, and when the shutter door reaches the closed position, the sliding stud is moved to the side of the resilient contact piece. A shutter door device is disclosed in which a sliding stud is sandwiched between an elastic contact piece and one inner wall of a guide groove.

[0005]

Although the shutter door device is effective for preventing the generation of impact noise and rebound, it is necessary to provide an elastic contact piece on the stopper member. In order to provide a function, it is necessary to reduce the thickness of the elastic contact piece. In addition, since the elastic contact piece is exposed in the guide groove, there is a possibility that the elastic contact piece may be damaged due to mischief or the like.

According to the present invention, furniture which prevents the occurrence of impact noise and rebound when the sliding door reaches the closed position, enables smooth opening and closing of the sliding door, and prevents exposure of easily breakable members. It is an object of the present invention to provide a sliding door device in such as.

[0007]

According to the present invention, the above-mentioned problem is solved as follows. (1) An elastically deformable slider having a substantially inverted V-shape when viewed from the side and having flanges as sliding surfaces at both lower ends is provided on the lower surface of the leading end of a sliding door which is slidably guided along a guide groove in furniture or the like. A holding portion having a narrow portion capable of deforming the slider and a wide portion capable of continuously releasing the deformation of the slider is provided near the position where the tip of the sliding door stops in the mounting and guide groove. .

(2) In the above item (1), the narrow portion and the holding portion are formed in the guide groove by a stopper member mounted in the guide groove.

FIG. 1 is a perspective view showing an embodiment in which the sliding door device of the present invention is applied to furniture, and FIG.
3 is a perspective view of the slider (2) in FIG. 1, and FIG. 3 is a perspective view of the slider (2) in FIG.

[0010] A guide groove (4) provided in the lower front part of the furniture body
A plurality of slides (5) are attached to the lower surface of the left and right sliding doors (3) (the left one is not shown) which is slid along the sliding door (3). ) Slides in the guide groove (4), whereby the sliding door (3) is guided along the guide groove (4).

An elastically deformable slider (2) is attached to the lower surface of the leading end of the sliding door (3). Slider (2)
Is formed by connecting flange pieces (2b) (2b) as sliding surfaces to both front and rear lower ends of a substantially inverted V-shaped main body (2a) in side view, and the opening width of the inverted V-shaped main body (2a) (L) can be elastically deformed in a direction to expand or contract. The slider (2) is generally formed of a synthetic resin or metal.

FIG. 4 is an enlarged perspective view of the dashed line circle (A) in FIG. The slider (2) is mounted by fitting the main body (2a) into a mounting recess (6) provided on the lower surface of the leading end of the sliding door (3).

Collar pieces (2b) (2b) at the front and rear lower ends of the slider (2)
Is located outside and below the mounting recess (6), and the lower surface thereof is
It functions as a slide surface.

A stopper member (1) is provided in the guide groove (4) near the position where the tip of the sliding door (3) stops when the sliding door (3) is closed.

The stopper member (1) has a substantially T-shape facing forward as viewed in plan, and as shown in FIG. 2, a thin piece (1b) (1b) extending perpendicularly to both sides from the rear end of the main body (1a). And each thin piece
(1b) and a thick end (1c) provided at the tip.

The length of the main body (1a) in the front-rear direction is the guide groove.
The stopper member (1) is almost equal to the width of (4)
(4) When the screw (7) is fixed by inserting the screw (7) into the mounting hole (1d) formed in the main body (1a) by contacting the rear wall (4a) with the main body (1a)
Is in contact with the front wall (4b) of the guide groove (4).

FIG. 5 is a plan view for explaining the interaction between the slider (2) and the stopper member (1) in the sliding door device of the present invention, and the sliding door (3) is omitted.

As shown in FIG. 5A, both the thick end (1c) of the stopper member (1) fixed in the guide groove (4) and the front wall (4a) of the guide groove (4). As a result, a narrow portion (M) in which the front and rear widths of the guide groove (4) are narrowed is formed, and the thin portion (1b) of the stopper member (1) and the guide groove (4) are successively formed.
A wide portion (N) wider than the narrow portion (M) is formed by both of the front walls (4b).

To close the sliding door (3), slide the sliding door (3) in FIG.
(a) is slid along the guide groove (4) in the direction indicated by the arrow, and the slider (2) attached to the lower surface of the leading end of the sliding door (3) is
When approaching the stopper member (1), as shown in FIG. 5 (b), the slider (2) moves the thick end of the stopper member (1).
Contact (1c).

The thick end (1c) and the front wall of the guide groove (4)
The dimension of the narrow part (M) between (4a) and
The dimension (W) between the ends of the flange pieces (2b) and (2a) before and after (2) is set to be smaller.

Therefore, as shown in FIG. 5 (c), when the slider (2) passes through the narrow portion (M), it is elastically deformed and the ends of the two flange pieces (2b) (2a) are deformed. The width between the parts is small and the narrow part
The dimensions (W ₁ ) are almost equal to the dimensions of (M)
Pass (M).

In order to elastically deform the slider (2), a corresponding load is required, and by the reaction of this load,
A stopper function acts on the sliding door (3) via the slider (2). Due to this stopper action, the moving speed of the sliding door (3) when closing the sliding door (3) is reduced.

Next, the slider (2) is fitted into the wide portion (N) as shown in FIG. 5 (d).

The dimension of the wide portion (N) is almost the same as or slightly smaller than the dimension (W) between the ends of the flange pieces (2b) and (2a) of the slider (2) in the free state. Therefore, the slider (2) is moved to the wide portion while the elastic deformation is almost restored.
The movement is restricted in (N), and the sliding door (3) is kept closed.

When the slider (2) passes through the narrow portion (M), the magnitude of the load required for elastically deforming the slider (2) depends on the thickness of the top of the slider (2) and the thickness of the slider (2). An appropriate design can be made by selecting the material to be used.

Usually, the magnitude of the load is set to such a value that the slider (2) stops naturally when the slider (2) passes through the narrow portion (M) and reaches the wide portion (N). It is desirable to design it.

Further, even after the slider (2) reaches the inside of the wide portion (N), the size of the wide portion (N) is adjusted in order to allow a certain stopper function.
It is also recommended that the dimension (W ₂ ) be slightly smaller than the dimension (W) between the ends of both flange pieces (2 a) and (2 a) in a state where (2) is not elastically deformed.

If the inertia of the sliding door (3) is large and the slider (2) does not stop naturally in the wide portion (N), the side surface of the main body (1a) of the stopper member (1) serves as a stopper. Acts to stop the sliding door (3).

At this time, the slider (2) is a stopper member
Due to the recoil that collided with the side surface of the main body (1a) of (1) or the recoil that collided with the tips of the sliding doors (3) located on both sides of the stopper member (1), the slider (2) caused the narrow portion to move.
Attempts to rebound beyond (M), but normally no load is applied to the slider (2) to give elastic deformation beyond the narrow portion (M), so that rebound is prevented.

On the other hand, when the sliding door (3) is moved again in the opening direction, the slider (2) is elastically deformed, and the narrow portion (M) is deformed.
And the door can be easily opened.

It is needless to say that the slider (2) having the same configuration and operation as described above is also provided for the left sliding door (not shown).

[0032] A shock absorbing member (8) is provided on the tip end surface of each sliding door (3).
By adding the above, it is possible to reduce the impact sound when the leading end surfaces of the opposing sliding doors (3) meet, and to reduce the recoil at the time of joining between the leading end surfaces.

FIG. 6 shows another embodiment of a stopper member (1). This stopper member (1) is used in a case where the tip of a sliding door abuts on one end of an opening of furniture to close the door. This corresponds to the one shown in FIG. 2 in which one thin piece (16) and one thick end (1c) are cut off.

The slider (2) in the embodiment described above
Of the stopper member (1) is constituted by a thin piece portion (1b) of the stopper member (1), a front surface of the main body portion (1a), and one wall surface of the guide groove (4).

However, in the case of a type in which the tip of the door is closed by contacting the end face of the opening of the furniture with the stopper member,
The body part (1a) of (1) is not always necessary, and the thin piece part (1b)
Of the guide groove and one wall of the guide groove (4)
The holding portion of (2) may be formed.

[0036]

According to the present invention, the following effects can be obtained. (1) According to the first aspect of the present invention, it is possible to prevent an impact sound and a rebound when the sliding door reaches the closed position, and to smoothly open and close the sliding door. In addition, since the movable thin member that is easily damaged such as elastic deformation is not exposed to the outside, there is no risk of being damaged by mischief or the like.

(2) According to the second aspect of the present invention, the narrow portion for preventing the primary stopper function and the rebound and the wide portion constituting the holding portion of the slider when the sliding door is closed are easily formed. can do.
