Description

  The present invention relates to a bathroom door.

  Patent Document 1 discloses that an opening / closing valve and a cover material are provided at an opening of a frame of a bathroom door. In the bathroom door of this patent document 1, the on-off valve and the cover material are integrated, and the on-off valve is swingably supported by the cover material, and the on-off valve and the cover material extend over the entire left and right direction of the opening of the frame. It is arranged.

JP 2010-222846 A

  However, in the technique of Patent Document 1, since the cover material and the support portion of the on-off valve are integrated, the cover material is arranged over the entire left and right direction of the opening of the frame. When deformed due to aging, the support portion of the on-off valve is also deformed, making it difficult for the on-off valve to open or close. In particular, when a cover material is provided over the entire left and right direction of the opening, the cover material is likely to bend due to its own weight, and the cover material may be deformed.

  Then, this invention aims at provision of the bathroom door which can hold | maintain a ventilation function even when a cover material deform | transforms.

The invention according to claim 1 includes an opening provided in the frame, a plurality of ventilation units, and a cover material, each ventilation unit including an opening / closing valve and a support that supports the opening / closing valve in a swingable manner. And end caps provided on the left and right sides of the support, respectively, are detachably attached to the opening of the frame, and the cover material is attached to the bathroom side of the ventilation unit at the opening of the frame, The ventilation unit is a bathroom door characterized in that the end caps are arranged next to each other and the adjacent end caps are detachably engaged with each other.
In the present invention, the frame includes a shoji fold.

According to the first aspect of the present invention, since the cover material and the support for the on-off valve are separated from each other, the opening and closing of the on-off valve is not hindered even if the cover material is deformed. Can be held.
Since a plurality of ventilation units are provided in the left and right direction of the opening of the frame or bag, ventilation is performed on the left and right of the opening compared to the case where one ventilation unit is provided over the entire left and right direction of the opening. Even when is biased, one of the on-off valves can be opened and closed smoothly.
Since there are multiple ventilation units, even if the friction between the on-off valve and the support increases due to dust or the like and the on-off valve of one vent unit cannot be opened or closed, Ventilation can be secured.
Since one ventilation unit can be used in common for bathroom doors of various widths and the width of other ventilation units can be adjusted, the same type of ventilation unit can be used in common.
