Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a hanging door type sliding door generally called a flat sliding door, that is, when the sliding door is in a closed state, both the left and right sliding doors are on the same plane, and when either one of the sliding doors is opened, the other sliding door is opened. This relates to a flat sliding door that moves to the back side of the sliding door.
The main purpose of this invention is to provide a flat sliding door that can be reliably and smoothly opened and closed using a unique and simple mechanism that has never been seen before.

The details of the present invention will be described below based on an embodiment shown in the drawings.

In Figures 1 to 4, number 1 is a long main rail with a straight central part and curved ends IA and IB diagonally in front of the furniture, which is the top plate of the furniture frame A. It is attached to the front downward direction of 2. Historically, a pair of auxiliary rails 3.3 are provided that extend obliquely forward from the middle portion of the main rail in a diagonally forward direction, and each of the auxiliary rails 3.
．． 3 and the main rail 1 are each provided with a switching joint 4.4.

Reference number 5.5' is a sliding door, which is provided with a first sliding body 7A and a second sliding body 7B via hanging hook members 6.6 on both ends of the upper end surface thereof. ing. When these left and right gravitational forces 5.5' are in the flat state and in the closed position, the first sliding body 7A is slidably fitted into the curved ends IA and 1B of the main rail, respectively. Furthermore, the second sliding bodies 7B are respectively fitted into the dedicated auxiliary rails 3.3.

Then, the switching joynode 4.4 beams p- and ("
It is formed into an abbreviated shape by arms 4A and 4B, and is rotatably provided by a pivot 1PII14C. When the left and right sliding doors are closed, the first door 4A is placed in a position where it closes its exit (-1) and passes through the main door (1). When the sliding door 5 is opened, the second sliding body 7B on the auxiliary rail 3 crosses the main rail 1 together with the main rail 1 and switches to the position where it blocks the main rail, and at the same time the second arm 4B crosses the auxiliary rail 37. It is designed to be placed in position.

In the configuration of ``-'', the left and right sliding doors are 5.5 in Figure 1.
' is in a closed state with a flat fl attitude. From this state, when the sliding door 5 on the gold stone side is pulled in the opening direction, that is, to the left, the first arm 4A of the switching joint 4 is pushed and rotated by the movement of the second sliding body 7B of the sliding door, and crosses the main rail 1. and switch to the position where the eye main rail is blocked. At the same time, the second arm 4B is positioned to cross over the auxiliary rail 3.

Then, the first and second sliding bodies 7A, 7B of the sliding door 5 both slide on the main rail, and the right sliding door 5 moves to the back side of the left sliding door 5' as shown by the chain line in the figure. You can also open the door.

Also, when closing this right side sliding door 5, the second sliding body 7B
is transferred to the auxiliary rail 3 via the first arm 4A of the switching joint, and at the same time comes into contact with the second arm 4B to push and rotate it, returning it to the state shown in Figure 1, that is, the main rail penetration position. be.

As described above, the present invention includes a main rail and an auxiliary rail fixed to a furniture frame, and a switching joint that automatically switches between the main rail and the auxiliary rail as the sliding body moves, and The second sliding body placed on the auxiliary rail in the closed position shifts from the auxiliary rail to the main rail when the sliding door is opened, and conversely, when the sliding door is closed, the second sliding body switches from the main rail to the auxiliary rail via the switching joint. Therefore, for example, the rail itself, which is conventionally provided, is divided into sections I- for the right sliding door and the left sliding door, and these rails are alternately phased via a link mechanism. The structure is significantly simpler than that of a structure that is configured to swing and displace as shown in FIG.

It may also be composed of

Also, in the above embodiment, only the upper piece of each sliding door was suspended and moved one step, but it would be more stable if the tip end of the sliding door was formed to be guided by a suitable guide, for example, a track formed by fitting concave and convex grooves. It would be possible to obtain a good running operation.

Claims (1)

[Claims] A main rail which is fixed to a furniture frame and whose middle part is straight and whose ends are bent toward the front of the furniture, and a switching joint from the middle part of the main rail toward the front of the furniture. ,
3゜It consists of a first sliding body and a second sliding body attached to both ends of the upper or lower end face of a pair of left and right sliding doors, and in the closed position of the left and right sliding doors, the first sliding body is attached to the bent part of the main rail. The second sliding body is slidably fitted into the auxiliary rail. Further, the switching joint is located in a position where the left and right sliding doors are closed, closing the outlet of the auxiliary rail and penetrating the main rail, and when opening either of the sliding doors, the joint marked ff1J is assisted by the movement of the second sliding body. It is configured to switch to a position where the connection between the rail and the main rail is achieved, and when the second sliding body moves from the main rail to the auxiliary rail when closing the sliding door, this movement causes the joint to flat sliding door configured to close the exit of the auxiliary rail and return to the position where it passes through the main rail.
