Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention brings at least two doors into an opening of a cabinet, etc., by abutting each other at their inner ends, thereby closing the doors in a planar manner. The present invention relates to an outset or inset plane closing sliding door device that creates a stacked open door state by moving one door from this state so that it overlaps the front side or back side of the other door.

《Prior art》 Conventional general sliding doors have a step between the doors in the thickness direction of the door, which detracts from the aesthetic appearance, so the above-mentioned flat sliding sliding door is often used. However, due to the structure of the existing door device, unless a gap is provided between the butting ends of both doors, the doors cannot be opened or opened, resulting in stacking of the doors. In use and production, there are cases where it is not possible to open the door, or the opening of the opening door cannot be made large, or it is not possible to open or move the door without chamfering the back surfaces of the butting ends of both doors into an inclined state. However, there are various problems in terms of both top and cost.

Additionally, a sliding device has been disclosed in Japanese Patent Application Laid-Open No. 195975/1983 for the purpose of simplifying the structure of the steady rest when opening and closing the door and maximizing the opening when opening the door. There is.

As shown in FIGS. 12 to 19, this device has two parts on both the left and right doors a and a' at either the upper or lower end of each, and at both the inner and outer ends in the axial direction of the door. guides b and b' are provided, and one guide c is provided at the other end at approximately the center in the door width direction, while an upper wall d and a lower wall e of the door mounting frame are provided.
is provided with runners f and g that engage the guides b, b' and c and guide the doors in the front and back direction in the width direction so that both doors can be freely opened and closed.

In the above device, the runner f is the main runner,
The runner g is used as a steady rest runner, and the main runner f has a straight part f' that moves in the door width direction (lateral direction) and in the front-rear direction so that each door a, a' can be opened and closed freely, and its left and right parts. It is formed by sloped parts f'', f'' at both ends and longitudinal guide parts f'', f'' on both left and right sides of the center part of the straight part f', while the steady rest runner g is It is formed by a straight part g' and inclined parts g'' at both left and right ends thereof, and according to the device, two parts are provided at one end of both the upper and lower ends of both doors a and a'. It is sufficient if the guides b, b' and the main runner f are not provided.
Since it is sufficient to provide one guide c and the above-mentioned simple runner g on the other end side, this type of device can be simplified.

However, in the above device, the main rail f is
2. Whether the guide c is installed on the upper wall d of the door mounting frame as shown in Figures 16 to 16 or the lower wall of the door mounting frame as shown in Figures 17 to 19, the guide c is located approximately at the center of the door in the width direction. For example, in order to open door a', hold the handle h and open the door.
a″ in the direction of the arrow i shown in the figure, FIG.
The door position shown by the solid line in FIG. 19 is ideal, but in reality, as shown in FIG. The inclined axis Y' connects guides b and c in the figure, and guides c and b' in Figure 19, respectively. Therefore, in the case of Figure 16, the lower right end of door a' does not move in the direction of arrow j shown in the figure. In the case of FIG. 19, the upper right end and lower left end of door a' move in the directions of arrows k and k' shown in the figure, and the door a' moves along the vertical axis Y.
The guides b, b', and c are tilted by an arbitrary angle relative to the runners f, g, and the respective straight parts f', g' There are problems such as the door cannot be pulled out, the opening operation of the door is not smooth, and the door closing operation is also not smooth.

<<Problems to be solved by the invention>> The present invention attempts to solve the above-mentioned problems by providing two guide shafts at one end of the upper and lower ends of both the left and right doors, and the other. One guide shaft is provided at each end, and the aforementioned main liner is installed on the upper and lower walls of the door mounting frame so that the left and right doors can be opened and closed by engaging each of the guide shafts. In a door device comprising a main door rail similar to the above-mentioned steady rest liner and a sub-door rail similar to the above-mentioned steady rest liner, one guide shaft at the other end is connected to the outside end in the door width direction of the one end. When the door is opened, the door uses the vertical axis as the rotation axis, so that the door can be closed smoothly. The purpose is to make it possible to do this and to simplify the structure.

《Means for solving the problem》 That is, in the present invention, the left and right doors are provided with two guide shafts at either the upper or lower ends of each, and at the inner and outer ends in the width direction of the door. At the same time, one guide shaft is provided at the other end, and the two guide shafts are engaged with the upper and lower walls of the door mounting frame to adjust the door width so that each door can be opened and closed freely. A main door rail formed of a linear part movable in the forward and backward directions, inclined parts at both left and right ends thereof, and longitudinal guide parts on both left and right sides of the central part of the straight part, and the one guide shaft mentioned above. A sub-door rail formed by a straight part that engages with the straight part and slope parts on both left and right sides of the straight part is arranged side by side,
Both the left and right doors are arranged so that their inner edges are brought together to form a flat closed door state, and one door is opened with the other door overlapped in the thickness direction. In the double-sliding door device, one guide shaft at the other end of the left and right doors is symmetrical with the guide shaft at the outer end in the door width direction at one end, and forms a substantially vertical axis. The above-mentioned problems are solved by arranging the above-mentioned doors so that they can be opened and closed using the above-mentioned vertical axis as a rotation axis.
