Embodiment Construction

[0027] Embodiments of the present invention will be described with reference to the drawings for a double-opening type automatic door device.

[0028] exist figure 1 Among them, the three-sided frame formed by bridging crosspieces 10 at the upper ends of the left and right vertical frames 1 and 2 vertically installed on the floor surface forms an entrance and exit. On the sides of the vertical frames 1 and 2, fixed The doors 3a, 3b and sliding doors 4a, 4b are constructed between the two fixed doors so as to be freely openable and closable toward the fixed door side, respectively. figure 1 It shows that the sliding doors 4a, 4b are in a fully closed state. In the drawings, the near side of the sliding doors 4a, 4b is taken as the outdoor, and the deep side is taken as the indoor.

[0029] The crosspiece 10 in the present invention is a fixed crosspiece 11 straddling the upper ends of the left and right vertical frames 1 and 2 in a fixed state, and a fixed crosspiece 11 connec...

Abstract

The invention provides an automatic door device. According to the conception that a cross piece in an entrance and exit can be divided into a fixed cross piece and movable cross pieces, the movable cross pieces are made light and sliding doors can be opened completely in any of a fully-opened state, a fully-closed state, and a midway-opened state. A cross piece (10) placed on the upper ends of a left longitudinal frame and a right longitudinal frame (1, 2) of an entrance and exit is designed to include a fixed cross piece (11) and bivalve type movable cross pieces (12a, 12b); the movable cross pieces are combined to the lower surface of the fixed cross piece (11) in a manner that the ends on the longitudinal frame sides are supported by shafts and the movable cross pieces can rotate through 90 degrees; fixed doors (3a, 3b) are suspended on the movable cross pieces (12a, 12b), and sliding doors (4a, 4b) are suspended to be able to move along the fixed doors. A drive device (20) used for driving the sliding doors (4a, 4b) to move and an engine unit (21) are arranged in the fixed cross piece (11); power transmission mechanisms (23, 30a, 30b) of the driving force are arranged to straddle the fixed cross piece (11) and the movable cross pieces (12a, 12b) and are in clamped fit with suspension device components (36a, 36b) of the sliding doors.

Description

technical field [0001] The present invention relates to an automatic door device. Specifically, it relates to an automatic door device in which a fixed door and a sliding door are arranged at an entrance and exit, and the sliding door is suspended and erected so as to be movable along the fixed door. The entrance is opened and closed, and if necessary, the fixed door and the sliding door are swung (turned 90 degrees) to fully open the entrance (fully open). Background technique [0002] A conventional automatic door automatically opens and closes a sliding door arranged at an entrance and exit along a fixed door. However, an automatic door device is known that not only performs the opening and closing operation, but also opens and closes the sliding door according to special circumstances, etc. The fully opened sliding door further swings integrally with the fixed door to open a wide entrance (Patent Document 1). [0003] That is, the conventional device of Patent Document ...
