Description

  TECHNICAL FIELD The present invention relates to the technical field of arcuate door devices for booths built at the entrances and exits of partitioned booths (rooms) such as toilet booths and shower booths.

Today, a so-called arcuate door device that opens and closes an entrance / exit by sliding an arcuate door along an arc trajectory as a door device to be built at the entrance / exit of a partitioned booth such as a toilet booth is proposed. Has been. As such an arc-shaped door device, conventionally, an entrance / exit is formed between the front panel side of the door front side and the door bottom side arranged at the front part of the booth, and the entrance / exit is slid to open / close. An arc-shaped door body and an arc-shaped suspension rail that is arranged so as to extend from the upper part of the doorway to the upper part of the booth and guide the opening and closing slide movement of the door body in a state of suspending the door body. The thing is known (for example, refer patent document 1).
By the way, in the structure configured to open and close the entrance / exit with an arcuate door suspended by an arcuate suspension rail as in Patent Document 1, a guide member for opening and closing the lower part of the door is provided. Otherwise, when the door is opened and closed, the lower part of the door may swing and a smooth opening and closing operation may not be performed. In particular, when the door is opened and closed vigorously, centrifugal force acts on the door and the lower part of the door is greatly shaken outward (front side, outer diameter side), thereby hindering a smooth opening and closing operation.
On the other hand, in a sliding door device using a normal flat door, a guide groove is provided at the lower part of the door, and a guide body that engages with the guide groove is provided on the housing side, so that the door can be opened and closed. Accordingly, the guide body moves in the guide groove relative to each other to suppress the shake of the lower portion of the door. Therefore, in the arc-shaped door device, it is also proposed to provide such a guide groove and a guide body to suppress the swing of the lower part of the door body. In this case, the opening / closing movement locus of the door body is an arc shape. Therefore, if only one guide body is provided, there is a problem that the guide body does not work effectively with respect to the shake of the door body in the radial direction, and the function of suppressing the shake of the lower part of the door body is inferior. .
Therefore, the inner and outer rails are provided at the lower part of the arc-shaped door, and the first and second rollers that are in pressure contact with the inner and outer rails on the door side are provided on the booth inner surface of the front wall on the door bottom side of the doorway. The technique (for example, refer patent document 2) which provided and suppressed the horizontal shake of the lower part of a door body is proposed. In this case, since the two guide bodies of the first and second rollers are provided, the function of suppressing the shake of the lower part of the door body is improved as compared with the case where only one guide body is provided. Can be planned.

By the way, the centrifugal force that acts on the door when opening and closing the arc-shaped door acts as described above to swing the lower part of the door outward, but the lower part of the door is outward. The centrifugal force to be shaken is received by a guide body that is provided with a guide body that engages with the lower part of the door as in Patent Document 2. In this case, in the thing of patent document 2, since the 1st and 2nd roller used as a guide body is constituted so that it may press-contact with the rail inside and outside on the door side, only the 1st roller contacted to the inner rail, The centrifugal force that shakes the lower part of the door body outward will be received. However, if there is only one place where the centrifugal force is received in this way, the door body is distorted around the place receiving the centrifugal force, and the distortion acts as a brake to open and close the door body smoothly. The problem that cannot be done.
Furthermore, when providing a guide body that engages with the lower part of the door body like the first and second rollers of Patent Document 2, the guide body is engaged with the door body side in both the closed state and the open state of the door body. Although it is necessary to provide in the position to perform, in the thing of patent document 2, both the 1st and 2nd rollers are provided in the booth inner surface of the door bottom side front wall part. For this reason, in order to prevent the engagement between the first and second rollers and the inner and outer rails on the door side even in the closed state, the remaining part of the closed door body (the door body is drawn into the booth in the closed state). It is necessary to set the length of the portion) longer than the amount of the engagement. However, if the left part of the closed door is set longer, the left and right width of the door will be increased accordingly, and the space in the booth in the closed state will be reduced, and the cost will increase. There are problems to be solved by the present invention.
