Description

The present invention relates to the technical field of an arcuate door device for a booth to be built at the entrance / exit of a partitioned (partitioned) booth (room) such as a toilet booth or a shower booth.

Today, as a door device to be built at the doorway of a partitioned booth such as a toilet booth, a so-called arc-shaped door device that opens and closes the doorway by sliding the arc-shaped door body along the arc trajectory is proposed. Has been done. Conventionally, as such an arcuate door device, an entrance / exit is formed between both front panel bodies on the door end side and the door end side arranged in the front part of the booth, and the entrance / exit is slid to open and close. It is composed of an arc-shaped door body and an arc-shaped suspension rail that is arranged from the upper part of the doorway to the upper part of the booth and guides the opening / closing slide movement of the door body while the door body is suspended. Is known (see, for example, Patent Document 1).
By the way, in the case of the arc-shaped door body suspended by the arc-shaped suspension rail as in Patent Document 1 in which the doorway is opened and closed, a guide member for opening and closing the lower part of the door body is provided. Otherwise, there is a risk that the lower part of the door will shake when the door is opened and closed, and smooth opening and closing operations will not be possible. In particular, when the door body is opened and closed vigorously, centrifugal force acts on the door body and the lower part of the door body swings greatly to the outer side (front side, outer diameter side), which hinders smooth opening and closing operation.
On the other hand, in a sliding door device using a normal flat door body, a guide groove is provided in the lower part of the door body, while a guide body engaged with the guide groove is provided on the skeleton side to open and close the door body. Along with this, it is generally performed that the guide body moves relative to the guide groove to suppress the runout of the lower part of the door body. Therefore, it is proposed that the arc-shaped door device also provides such a guide groove and a guide body to suppress the runout of the lower part of the door body, but in this case, the opening / closing movement locus of the door body is arcuate. Therefore, if only one guide body is provided, the guide body does not work effectively against the radial runout of the door body, and there is a problem that the function of suppressing the runout of the lower part of the door body is inferior. ..
Therefore, while the inner and outer rails are provided at the lower part of the arc-shaped door body, the first and second rollers that are in pressure contact with the inner and outer rails on the door body side are provided on the inner side surface of the booth on the front wall portion on the door tail side of the doorway. A technique has been proposed in which the lower part of the door body is provided to suppress lateral vibration (see, for example, Patent Document 2). In this product, since two guide bodies of the first and second rollers are provided, the function of suppressing the runout 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, as described above, the centrifugal force acting on the door body when the arc-shaped door body is opened and closed acts to swing the lower part of the door body outward, but the lower part of the door body is moved outward. The centrifugal force to be shaken is received by the guide body provided with the guide body engaged with the lower part of the door body as in Patent Document 2. In this case, in Patent Document 2, since the first and second rollers serving as guide bodies are configured to be in pressure contact with the inner and outer rails on the door body side, only the first roller that abuts on the inner rail is used. It will be subjected to centrifugal force that shakes the lower part of the door outward. However, if there is only one place that receives the centrifugal force in this way, the door body is distorted around the place that receives the centrifugal force, and the strain acts as a brake to smoothly open and close the door body. The problem arises that it cannot be done.
Further, when a guide body that engages with the lower part of the door body is provided as in the first and second rollers of Patent Document 2, the guide body engages with the door body side in both the closed state and the open state of the door body. However, in Patent Document 2, both the first and second rollers are provided on the inner side surface of the booth on the front wall portion on the door tail side. For this reason, the leftover portion of the closed door (the door is pulled into the booth in the closed state) so that the engagement between the first and second rollers and the inner and outer rails on the door side is not disengaged even in the closed state. It becomes necessary to set the portion) longer by the amount of the engagement. However, if the leftover part of the closed door is set long, the left-right width of the door becomes longer by that amount, which narrows the space inside the booth when the door is closed and increases the cost. There are problems to be solved by the present invention.

The present invention has been created for the purpose of solving these problems in view of the above circumstances, and the invention of claim 1 is for the front door side and the door tail side arranged in the front part of the booth. It is an arc-shaped door device for a booth for opening and closing the doorway formed between both front panel bodies, and the arc-shaped door device is opened and closed by sliding the doorway, and the doorway and the doorway.
