Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sliding door device for furniture and the like, and various sliding guides along a guide groove such as a sliding door and a shutter door for opening and closing various furniture such as a library and a storage, or a bellows type door for a partition. The present invention relates to a device that smoothly closes a sliding door.
[0002]
[Prior art]
In general, when closing the doors by abutting the front end surfaces of the two sliding doors, a stopper fitting for restricting the closing position of the two sliding doors is used, as described in, for example, JP-A-3-23992. However, when the door is closed, an abutment piece provided on the sliding door collides with the stopper fitting, and an impact sound is generated or the sliding door easily rebounds from the closed position to the open side.
[0003]
In addition, when the sliding door has a front end surface that abuts against the end face of an opening of furniture or the like and closes the door, a stopper metal fitting is usually not used, and when the door is closed, an impact sound and rebound are likely to occur. .
[0004]
As a countermeasure for this, Japanese Patent Application Laid-Open No. 8-189266 discloses a sliding hook that slidably fits in the guide groove at the lower end of the front end surface of the shutter door. When a stopper member having a barrier portion fitted between opposing inner walls of the guide groove and an elastic contact piece extending from the barrier portion along the guide groove is fixed, and the shutter door reaches the closed position A shutter door device is disclosed in which a sliding rod is brought into elastic contact with the side surface of the elastic contact piece, and the sliding contact is held between the elastic contact piece and one inner wall of the guide groove.
[0005]
[Problems to be solved by the invention]
The shutter door device is effective in preventing the occurrence of impact noise and rebound, but it is necessary to provide a resilient contact piece on the stopper member. In order to provide the elastic function of this resilient contact piece, It is necessary to reduce the thickness of the piece. In addition, since this elastic contact piece is exposed in the guide groove, it may be damaged by mischief or the like.
[0006]
The present invention prevents sliding noise and rebound from occurring when the sliding door reaches the closed position, smoothly opens and closes the sliding door, and prevents a breakable member from being exposed. An object is to provide an apparatus.
[0007]

A holding portion having a narrow portion that can be deformed and a wide portion that can continuously release the deformation of the slider is provided.
[0008]
(2) In the above section (1), the narrow portion and the holding portion are formed in the guide groove by the stopper member attached in the guide groove.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a perspective view showing an embodiment when the sliding door device of the present invention is applied to furniture, FIG. 2 is a perspective view of a stopper member (1) in FIG. 1, and FIG. 3 is a slider (2) in FIG. FIG.
[0010]
On the lower surface of the left and right sliding doors (3) (not shown on the left side) that are slidably guided along guide grooves (4) provided in the lower front of the furniture body, a plurality of sliders ( 5) is attached, and when the slider (5) slides in the guide groove (4), the sliding door (3) is guided along the guide groove (4).
[0011]
An elastically deformable slider (2) is attached to the lower surface of the tip of the sliding door (3).
The slider (2) is formed by connecting flanges (2b) (2b) as slide surfaces to both front and rear lower ends of a substantially inverted V-shaped body (2a) in side view, and an inverted V-shaped body (2a). ) Can be elastically deformed in the direction in which the opening width (L) increases or decreases. The slider (2) is generally formed of synthetic resin or metal.
[0012]
FIG. 4 is an enlarged perspective view in a dashed-dotted line circle (A) in FIG.
The slider (2) is attached by fitting the main body (2a) into a mounting recess (6) provided on the lower surface of the front end of the sliding door (3).
[0013]
As shown in FIG. 4, the front and rear lower end pieces (2 b) and (2 b) of the slider (2) are extended outwardly perpendicular to the sliding direction of the sliding door ( 3 ). It is located on the outer lower side of (6), and its lower surface functions as a slide surface.
[0014]
A stopper member (1) is provided near the position where the tip of the sliding door (3) stops in the guide groove (4) when the sliding door (3) is closed.
[0015]
The stopper member (1) has a substantially forward T-shape in plan view, and, as shown in FIG. 2, thin piece portions (1b) (1b) extending from the rear end of the main body portion (1a) to both sides at right angles, It consists of a thick end (1c) provided at the tip of the thin piece (1b).
[0016]
The length of the main body portion (1a) in the front-rear direction is substantially equal to the width of the guide groove (4), and the stopper member (1) is brought into contact with the rear wall (4a) of the guide groove (4) so that the main body portion (1a When the screw (7) is inserted and fixed in the mounting hole (1d) drilled in), the front end of the main body (1a) comes into contact with the front wall (4b) of the guide groove (4). .
[0017]
FIG. 5 is a plan view for explaining the mutual action of the slider (2) and the stopper member (1) in the sliding door device of the present invention, in which the sliding door (3) is omitted.
[0018]
As shown in FIG. 5 (a), the guide is provided by 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). A narrow portion (M) in which the front and rear width of the groove (4) is narrowed is formed, and subsequently, the thin piece (1b) of the stopper member (1) and the front wall (4b) of the guide groove (4) ) Forms a wide portion (N) wider than the narrow portion (M).
[0019]
To close the sliding door (3), the sliding door (3) is slid along the guide groove (4) in the direction indicated by the arrow in FIG. However, when approaching the stopper member (1), as shown in FIG. 5 (b), the slider (2) contacts the thick end (1c) of the stopper member (1).
[0020]
Note that the width of the narrow portion (M) between the thick end (1c) and the front wall (4a) of the guide groove (4) is the flange (2b) (2a) before and after the slider (2). It is determined to be smaller than the dimension (W) between the end portions.
[0021]
Therefore, as shown in FIG. 5 (c), the slider (2) is elastically deformed when passing through the narrow portion (M) and is dimensioned between the end portions of the two flange pieces (2b) (2a). , And has a dimension (W ₁ ) substantially equal to the dimension of the narrow part (M) and passes through the narrow part (M).
[0022]
In order to elastically deform the slider (2), a corresponding load is required. Due to the reaction of this load, a stopper acts on the sliding door (3) via the slider (2).
By this stopper action, the moving speed of the sliding door (3) when closing the sliding door (3) is weakened.
[0023]
Next, the slider (2) is fitted into the wide portion (N) as shown in FIG. 5 (d).
[0024]
The dimension of the wide part (N) is substantially the same as or slightly smaller than the dimension (W) between the ends of the flanges (2b) and (2a) of the slider (2) in the free state.
Therefore, the slider (2) is restrained from moving within the wide portion (N) with the elastic deformation substantially restored, and the sliding door (3) is held closed.
[0025]
When the slider (2) passes through the narrow portion (M), the amount of load required to elastically deform the slider (2) depends on the thickness of the top of the slider (2) and the material used. It is possible to design appropriately by selecting.
[0026]
Usually, the magnitude of the load is designed so that the slider (2) passes through the narrow part (M) and reaches the wide part (N) so that it naturally stops. It is desirable.
[0027]
Further, after the slider (2) reaches the wide part (N), the dimension of the wide part (N) is set so that the slider (2) is not elastically deformed in order to act to a certain degree of stopper function. It is also recommended that the dimension (W ₂ ) be slightly smaller than the dimension (W) between the ends of the two flanges (2a) (2a).
[0028]
If the inertia of the sliding door (3) is large and the slider (2) does not stop spontaneously in the wide part (N), the side surface of the main body part (1a) of the stopper member (1) acts as a stopper, Stop the sliding door (3).
[0029]
At this time, the slider (2) collides with the side surface of the main body (1a) of the stopper member (1), or the reaction between the tips of the sliding doors (3) located on both sides of the stopper member (1) collides with each other. The slider (2) tries to rebound beyond the narrow part (M). Usually, the slider (2) is subjected to a load that gives elastic deformation exceeding the narrow part (M). Therefore, rebound is prevented.
[0030]
On the other hand, when the sliding door (3) is moved again in the opening direction, the slider (2) is elastically deformed, passes through the narrow portion (M), and can be easily opened.
[0031]
It goes without saying that a slider (2) having the same configuration and operation as described above is also provided for the left sliding door (not shown).
[0032]
By attaching an impact mitigating member (8) to the front end surface of each sliding door (3), it is possible to reduce the impact sound when the front end surfaces of the opposing sliding doors (3) collide with each other. The reaction at the time of collision can be reduced.
[0033]
FIG. 6 shows another embodiment of the stopper member (1), and this stopper member (1) is used in the case of a type in which the front end of the sliding door abuts against one end of the opening of the furniture to close the door. 2, this corresponds to one of the thin piece (16) and the thick end (1c) cut out.
[0034]
The holding part of the slider (2) in the above-described embodiment is composed of the thin piece part (1b) of the stopper member (1) and the front surface of the main body part (1a) and one wall surface of the guide groove (4). Has been.
[0035]
However, in the case of a type in which the front end of the door is in contact with the end face of the opening of the furniture and the door is closed, the main body portion (1a) of the stopper member (1) is not necessarily required, and the front surface of the thin piece portion (1b) The holding portion of the slider (2) may be formed by the one wall surface of the guide groove (4).
[0036]
【The invention's effect】
According to the present invention, the following effects can be achieved.
(1) According to the invention described in claim 1, it is possible to prevent the generation of impact sound and rebound when the sliding door reaches the closed position, and to smoothly open and close the sliding door.
Further, since the movable and easily damaged thin member such as elastic deformation is not exposed to the outside, there is no possibility of being damaged due to mischief or the like.
[0037]
(2) According to the invention described in claim 2, it is possible to easily form the narrow portion that prevents the primary stopper action and rebound, and the wide portion that constitutes the holding portion of the slider when the sliding door is closed. it can.
