DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower frame of a bathroom door without a step on an upper surface and a watertight structure between the lower frame and the bathroom door.

[0002]

2. Description of the Related Art In order to prevent a danger of falling between a bathroom and a dressing room, a step on an upper surface of a lower frame is eliminated, and a level at an upper end of the lower frame is undressed from a floor surface of the bathroom. If it is aligned with the floor level of the room, the airtight material laid at the lower end of the bathroom door will not be able to adhere to the upper surface of the lower frame from the bathroom side. The airtight material housed at the lower end of the door can be lifted up and down to adhere to the upper surface of the lower frame from above, but in a bathroom, the amount of water sprayed on the lower frame is large, so the airtight material closely adheres to the upper surface of the lower frame from above. Anxiety remains in a watertight structure.

In Japanese Unexamined Patent Publication No. Hei 8-218748, each of the sliding doors of the folding door is supported by gravity hinges so that the airtight material is brought into close contact with the opening side of the folding door when the folding door is closed. The watertight effect is the same as that of Mitsuto 3002107 because it is in close contact with the flat upper surface of the frame.

In the case of a folding door, a groove is formed in the lower frame for a guide for guiding the opening and closing of the sliding door on the door end side. In Japanese Patent Application Laid-Open No. 8-218748, the lower frame is an integral type. Because
When used as a bathroom door, it is difficult to remove water or dust that accumulates inside the groove.

In view of the above background, the present invention proposes a lower frame and a watertight structure of a bathroom door with good cleaning work while ensuring watertightness of the lower frame.

[0006]

According to the first aspect of the present invention, the lower frame is located on the bathroom side with a groove in the expected direction between the lower frame body whose upper portion is located on the undressing room side and the upper portion of the lower frame body. By dividing the lower frame into two parts, the lower frame attachment being detachable from the lower frame main body, the workability of cleaning the lower frame is enhanced, and the dust accumulated in the groove is easily removed. The lower frame attachment has an upper speculative piece located at the same level as the upper part of the lower frame main body and a find piece that extends in parallel from the lower side in the speculative direction,
A drain hole for draining water collected in the groove into the bathroom is formed in each of the find pieces.

Further, the lower frame is divided into a lower frame main body and a lower frame attachment with the groove interposed therebetween. Since the material can be brought into close contact with the upper portion of the lower frame main body and the upper portion of the lower frame attachment from the bathroom side toward the dressing room side, the water from the bathroom can be reduced as compared with the case where the airtight material collides with the upper surface of the lower frame from above. The effect of preventing intrusion into the dressing room side is improved.

According to the second aspect, the lower frame attachment is engaged with the lower frame main body in the prospective direction, and the state is detachably inserted between the lower frame main body and the lower frame attachment so that the lower frame attachment is in the prospective direction. By holding with the connecting block that restrains movement, the lower frame attachment
Ensures stability when connected to the lower frame body.

In this case, since the lower frame attachment is attached to the lower frame main body by engagement, the work of attaching and detaching the lower frame attachment is simplified, and the connecting block can be freely attached to and detached from the lower frame attachment. The ease of cleaning the main body and the lower frame attachment is maintained.

According to a third aspect of the present invention, the length of the lower frame attachment is made shorter than the length of the lower frame body, and the hinge for supporting the bathroom door is sandwiched between the lower frame attachment and the vertical frame. The work is simplified, and the workability of cleaning the lower frame is ensured even when the hinge is installed on the lower frame.

Since the hinge is sandwiched between the lower frame attachment and the vertical frame, it is not necessary to drill a hole in the lower frame body for attaching the hinge, and watertightness at the hinge portion of the lower frame body is eliminated. A decline in sex is avoided.

In the fourth aspect, the airtight material at the lower end of the bathroom door is laid in parallel in the expected direction, so that the airtight material on the undressing room side is placed above the lower frame main body when the bathroom door is closed. The material is brought into close contact with the upper part of the lower frame attachment from the bathroom side to the undressing room side to increase the water tightness between the bathroom door and the lower frame.

[0013] In this case, the airtight material on the bathroom side discharges water to the bathroom side, and the airtight material on the undressing room side discharges water exceeding the airtight material on the bathroom side into the groove.
