Description

[Detailed description of the invention] "Industrial application field" This invention relates to a flat type sliding door in which a draw mechanism operates so that the glass surface of each sliding sash becomes the same when the window is closed.

"Background of the invention" Generally, sliding doors have steps on the glass surface. For this reason, when a surrounding object is reflected and reflected on the glass surface, the image is distorted due to a step between the glass surface of the outdoor sliding door and the glass surface of the indoor side, which is not preferable from the viewpoint of beauty. Particularly when the whole building is covered with glass, the tendency is strong because the whole building is seen as a mirror.

In the case of a building window, if the windows are cleaned by a machine, it is advantageous that the glass surface is uniform, so that the structure of the cleaning machine can be simplified. For this reason, flat sliding doors are used.

2. Description of the Related Art Various types of flat-type sliding doors, particularly a pulling mechanism, have been devised and put into practical use.

As an example, there are a structure shown in FIG. 11 and a structure shown in FIG.

The pulling mechanism shown in FIG. 11 is proposed by Japanese Utility Model Application Laid-Open No. 61-91969. Rails 2A and 2B are formed on the indoor side of the window frame 1 and these rails 2A and 2B The rails 2A and 2B are curved to the outside, and the sliding door 3 is drawn to the outside of the room by the curvature of the rails 2A and 2B.

In this structure, the door wheel 5 can be freely rotated about the vertical axis 6, and changes the direction of the door wheel 5 following the curve of the rail 2A so that the falling door accident does not occur.
Is guided in the outdoor direction.

On the other hand, the drawing mechanism shown in FIG. 12 is the drawing mechanism proposed in Japanese Utility Model Publication No. 60-37987.

This pulling mechanism is a rail 2 formed on the lower frame and the upper frame.
A and 2B are formed in a straight line.
And the lower lever 3B is provided with a turning lever 7 that can turn in the horizontal direction.
The pivoting free end of the pivoting lever 7 is provided with a door wheel 5 and the pivoting free end of the lever 7 on the upper frame side is provided with a projection 8 which engages with a rail 2B formed on the upper frame. By extruding the sliding door 3 in the outdoor direction, the rotating lever 7 rotates to move the sliding door 3 in the outdoor direction, and the sliding door 3 becomes flush with the surface of the other sliding door 4.

[Problems to be Solved by the Invention] In the conventional flat sliding door, the structure of a metal fitting interposed between the shoji 3 and the door roller 5 is complicated and large-scale.

In addition, in order to store the supporting brackets, the apparent dimensions of the overlapping frames must be increased in the case of FIG. 10 and the apparent dimensions of the upper and lower frames 3A and 3B must be increased in the case of FIG. Design is significantly impaired.

Further, the metal fittings interposed between the shoji 3 and the door wheel 5 must have the same complicated function as the weight of the shoji, and in particular, a pulling means for moving the shoji 3 toward the outside and inside the room at the window closing position. The drawback is that the pulling means must be costly in order to impart durability to the pulling means because of the excessive force applied to the pulling means.

A first object of the present invention is to provide a durable flat sliding door which is simple and durable against indoor and outdoor movements at a window position of a shoji.

A second object of the present invention is to provide a flat sliding door with a reduced size and a good appearance.

[Means for Solving the Problems] In the present invention, the rail supporting the inner shoji has a movable rail structure capable of moving in the indoor and outdoor directions, and a structure capable of moving the shoji in the indoor and outdoor directions on the movable rail. It is characterized by the following point.

According to the structure of the present invention, the rail provided on the window frame has a movable rail structure as a structure for moving the shoji in the indoor direction and the outdoor direction, thereby making it unnecessary to accommodate the movable mechanism in the shoji. .

Therefore, it is not necessary to make the pillar of the shoji thick, and the shoji can be made small.

Furthermore, by using a movable rail structure, the structure of a portion for moving the shoji in the indoor direction and the outdoor direction can be simplified. Therefore, an advantage that a durable flat sliding door can be obtained is obtained.

"Embodiment" Figs. 1 to 10 show an embodiment of the present invention.

In FIG. 3, reference numeral 10 denotes a window frame, 20 denotes an inner shoji, and 30 denotes an outer shoji. The window frame 10 includes an upper frame 10A, a lower frame 10B, and a vertical frame 10C.

In this example, a case is shown in which both the inner sash 20 and the outer sash 30 are double sliding windows that can be pulled. For this reason, the lower frame 10B has the first
As shown in the figure, a fixed rail 11A for inner shoji and a rail 12 for outer shoji are provided.

The outer sash rail 12 is formed over the entire lower frame 10B, while the inner sash fixed rail 11A is formed in a half area of the lower frame 10B. That is, as shown in FIG. 2, a fixed rail 11A for the inner sash is formed in the left half, and the movable rail 13 shown in FIG. 1 is provided in the other half. Also upper frame 10
A is also provided with a fixed rail 11B and a movable rail 14 for a shoji.

In this manner, the sash 30 can be moved over the entire range of the window frame 10 by the sash rail 12. In addition, inner shoji 20
Also, when the movable rails 13 and 14 are in the posture shown in FIG. 1, the entire range of the window frame 10 can be moved.

When the inner sash 20 is at a position facing the movable rails 13 and 14, the inner sash 20 can move from the indoor side to the outdoor side and vice versa by the movement of the movable rails 13 and 14.

The upper end of the movable rail 14 is pivotally supported at the upper end with respect to the window frame 10, and the lower end rotates in an arc. For this reason, the upper door roller 21 is supported by the support tool 22 so that it can be moved up and down in the vertical direction. In this example, the spring 22A receives a repulsive force from the support 22 and is elastically pressed against the movable rail 14.

On the other hand, the lower movable rail 13 is a movable rail in this invention.
An arc surface 13A is formed at the lower end of 13 and this arc surface 13A is
The upper end of the movable rail 13 is swingably supported by rolling on a plane 10BB provided on B.

The curvature of the arc surface 13A is selected to be an arc centered on the upper end of the movable rail 13. By selecting this circular arc, the upper end of the movable rail 13 moves horizontally without moving up and down. As a result, the inner sash 20 moves horizontally without moving up and down when moving in the expected direction, and the energy required for the movement can be reduced.

In other words, when the inner shoji 20 moves in the expected direction and moves up and down due to the structure of the support mechanism, energy for moving the weight of the shoji up and down is required. As a result, the resistance when moving the shoji is increased. For this reason, an unreasonable force is applied to the pulling means described later, but this invention solves this drawback and allows the shoji to be moved in the anticipated direction with a small force.

In this example, a curved plate 13B constituting an arcuate surface 13A provided at the lower end of the movable rail 13 is inserted into a cylindrical portion 15 formed on a lower frame 10B, and the curved plate 13B is supported by the cylindrical portion 15, thereby moving the movable rail 13. This shows a case where it is swingably supported.
