In addition, the upper frame 13 and the lower frame 14 are formed with a guide structure and a groove-like structure for guiding the opening and closing movement of the shoji 2 and fixing and supporting the sleeve portion 3. Details of these are described below. will be described later.

The shoji 2 is a door portion that automatically opens and closes in the automatic door 100 . The shoji 2 may be fitted into the outer frame 1, for example, in a kendo style. The shoji 2 opens and closes by being driven by an engine unit housed inside the frame of the upper frame 13, for example. 1 and 2 show the automatic door 100 with the shoji 2 closed. FIG. 3 shows a state (half-open state) of the automatic door 100 in which the shoji 2 is being opened from the closed state (see FIGS. 1 and 2).

As shown in FIG. 1, the shoji 2 has a rectangular shoji side frame 4 and a rectangular first door panel 21 fitted and fixed in a rectangular ring of the shoji side frame 4 . The first door plate 21 is, for example, a metal plate, a glass plate, or the like. Below, the case where the first door plate 21 is a glass plate is illustrated and demonstrated.

In the automatic door 100, the shoji 2 has the shoji-side frame 4, and the first door plate 21 is fitted into the shoji-side frame 4 so that the shoji 2 can be handled as a unit of member. Even fragile items like plates are easy to handle. As a result, the workability of assembling the automatic door 100 requiring assembly of the shoji 2 and installation at the installation site is enhanced. For example, it is possible to easily perform work such as assembling the shoji 2 in advance at a factory, transporting it to the installation site, and assembling it.

As shown in FIG. 2, when the shoji 2 is in the closed state, the shoji-side frame 4 is a door frame 41 that abuts on the inner surface of the first vertical frame 11 of the outer frame 1 in the facing direction, that is, the left side. , a first interlocking frame 42 that overlaps with the sleeve portion 3 when viewed from the projected direction, a first upper frame 43 that is guided by the upper frame 13 when the shoji 2 opens and closes, and the shoji 2, as shown in FIG. It has a first lower frame 44 guided by the lower frame 14 when opening and closing. The door frame 41, the first meeting frame 42, the first upper frame 43 and the first lower frame 44 are linear frames. The first door plate 21 may be fixed to the shoji-side frame 4 by being fitted into a groove formed in the inner surface of the rectangular ring of the shoji-side frame 4 , for example. 4 shows a cross-sectional view taken along the line IV-IV in FIG. 3, which is a so-called vertical cross-sectional view.

The door frame 41 is a frame extending vertically. The door frame 41 is hidden by the first vertical frame 11 of the outer frame 1 when the shoji 2 is in the closed state, when viewed from the prospective direction. In this embodiment, when the shoji 2 is in the closed state, the door frame 41 is fitted into the first vertical recess 11a and accommodated. It overlaps with the first vertical frame 11 and is hidden by the first vertical frame 11 even when viewed from the back side (outdoor side, outside of the building). As a result, the door frame 41 is supported by the first vertical concave portion 11a of the first vertical frame 11, and the strength of the shoji 2 against the load in the direction of projection is improved. In addition, since the door frame 41 is concealed by the first vertical frame 11, the automatic door 100 has a neat appearance and is improved in design. In addition, since the shoji 2 is automatically opened and closed, there is no particular need to provide a handle for opening and closing the door frame 41, and the door frame 41 is hidden by the first vertical frame 11 and the door is closed. The fact that the front frame 41 is fitted into the first vertical recess 11a and accommodated does not hinder the use of the automatic door 100 at all.

The door frame 41 may be completely fitted into the first vertical recess 11a and completely hidden by the first vertical frame 11 of the outer frame 1, or partly fitted into the first vertical recess 11a and fitted into the first vertical recess 11a. The intricate part may be hidden by the first vertical frame 11 . When the door frame 41 is completely fitted into the first vertical recess 11a and completely hidden by the first vertical frame 11 of the outer frame 1, the depth of the first vertical recess 11a in the viewing direction is The depth should be at least the same as the width of the door frame 41 in the viewing direction, and preferably greater than the width. If the depth in the viewing direction of the first vertical recess 11a exceeds the width in the viewing direction of the door end frame 41, the door end surface of the door end frame 41 may be fitted with a cushioning material such as rubber. Even if there is, the door frame 41 can be completely concealed. Further, even if the door contact surface of the door frame 41 is not fitted with a cushioning material such as rubber, the depth of the first vertical recess 11a in the viewing direction exceeds the width of the door frame 41 in the viewing direction. With the depth, the door frame 41 can be completely concealed and the door contact surface of the door frame 41 and the bottom surface of the first vertical recess 11a can be separated from each other when the shoji 2 is closed. As a result, for example, it is possible to prevent the occurrence of a collision sound when the shoji 2 is closed.

The first meeting frame 42 is a frame member extending vertically. The first meeting frame 42 approaches the second vertical frame 12 of the outer frame 1 when the shoji 2 is opened. In this embodiment, a predetermined gap is ensured between the first meeting frame 42 and the second vertical frame 12 when the shoji 2 is fully opened. This prevents accidents such as pinching fingers.

As shown in FIG. 4, the first upper frame 43 is a frame member extending along the viewing direction. The first upper frame 43 is guided by a groove-shaped guide structure formed in the upper frame 13 of the outer frame 1 to realize the sliding opening and closing of the shoji 2 . In this embodiment, as shown in FIG. 4, a guide frame 13G is formed by folding the lower surface of the front side of the upper frame 13 upward. , the first upper frame 43 is fitted into a guide rail-shaped concave portion. The first upper frame 43 realizes the sliding opening and closing of the shoji 2 by being guided by a guide rail-shaped concave portion formed by the guide frame 13G. In the present embodiment, the first upper frame 43 is in a state of being fitted into and housed in a guide rail-shaped concave portion formed by the guide frame 13G. It is hidden. As a result, the first upper frame 43 is supported by the upper frame 13, and the strength of the shoji 2 against the load in the projection direction is improved. In addition, since the first upper frame 43 is concealed by the upper frame 13, the automatic door 100 has a neat appearance, and the design is improved.

The first upper frame 43 may be completely hidden by the upper frame 13 of the outer frame 1 or may be partially hidden by the upper frame 13 .

The first lower stile 44 is a frame member extending along the viewing direction. The first lower frame 44 is guided by a rail portion 14L having a groove-shaped guide structure formed in the lower frame 14 of the outer frame 1, thereby realizing the sliding opening and closing of the shoji 2. As shown in FIG. For example, a groove 14a extending in the facing direction may be formed in the upper surface of the rail portion 14L. When the door roller of the shoji 2 is arranged on the lower surface of the first lower frame 44, the door roller travels along the groove 14a, so that the shoji 2 is guided by the lower frame 14 at the time of opening and closing. It should be noted that the first lower frame 44 is exposed and visible when viewed from the prospective direction.
