Description

  The present invention relates to an opening / closing device for a double swing type hanging door provided at an entrance of an office or a hospital room.

  A pair of left and right guides are arranged on the space member arranged above the doorway (opening) to the door pocket so that the pair of left and right guides are inclined at the center in the left and right direction of the opening. A side guide wheel is provided in the vicinity of the door side end of the pair of left and right guide means so that the rotation axis thereof is horizontal, A wire is hung around the guide car in a substantially loop shape, and a pair of left and right suspension doors are connected to the wire so that the other suspension door moves in the opposite direction by the movement of one of the suspension doors. In order to remove the slackness of the wire, a slack prevention means comprising a plurality of rotating bodies 1 for bending the cable was provided.

  That is, since the guide means has a low central portion and is provided with a high end in the left-right direction, the suspension door moves upward corresponding to the inclination of the guide means as it opens. Therefore, it is necessary to provide the wire with a slack corresponding to the rising distance of the suspension door. However, simply loosening the wire will cause problems such as the left and right suspension doors not moving quickly when opening and closing, and the wires falling off the side guide wheels when opening and closing the suspension doors. While removing the slack, it responded to changes in the overall length of the wire depending on the ascending and descending positions of the hanging door when opening and closing. For this reason, the structure is complicated, the number of parts is increased, the cost is increased, and the adjustment work of the slack preventing means is complicated.

The left and right wire connection seats 83 and 84 connected to the left and right suspension doors 6 and 6 are parallel to each other, and the inclination angle thereof substantially coincides with the inclination angle of the left and right rail members 5 and 5. The 1 wire 801 is connected to a portion of the wire 801 that is routed from above the left and right side guide wheels 81 and 82.
Accordingly, the left and right suspension doors 6 and 6 gradually move upward with the opening operation, but the second wire 802 and the first wire 801 to which the left and right wire connection seats 83 and 84 are connected are also inclined upward. Therefore, the required length of the entire wire 80 is hardly changed by the upward movement of the left and right hanging doors 6 and 6. Therefore, it is not necessary to give the wire 80 slack beforehand.

However, if the inclination angle of the left and right rail members 5 and 5 is set to be constant and the left and right guide wheels 81 and 82 are set to have a constant diameter, the width dimension of the doorway (the length of the left and right rail members 5 and 5) is set. Correspondingly, the mounting positions of the left and right side guide wheels 81 and 82 also change in the opening and closing direction, so that the angle of inclination of the left and right rail members 5 and 5 and the angle of the intersection of the second wire 802 and the first wire 801 are subtly. Depending on the vertical movement of the left and right suspension doors 6 and 6 accompanying the opening and closing operation, the required total length of the wire 80 will be different between when it is closed and when it is opened. It is possible to adjust within the range of tension when 801 and the second wire 802 are stretched to the left and right guide wheels 81 and 82 (so-called play range).
In addition, in the embodiment, two wires of the first wire 801 and the second wire 802 are used in consideration of easiness when laying them around, but it may be configured by one wire. Needless to say.

  As described in detail above, the present invention relates to an opening / closing device for a double swing type door, in which a wire is hung around a pair of side guide wheels, and a pair of intersecting wires has a predetermined interval. By tilting the pair of side guide wheels in a direction that intersects each other so that they are substantially parallel to each other in the horizontal direction, the structure is simple, the number of parts is low, and it can be manufactured at low cost.
