BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower frame structure for a bathroom sliding door.

[0002]

2. Description of the Related Art When a bathroom sliding door is attached to a bathroom doorway, a rail is provided on a lower frame of the bathroom sliding door to support a lower runner of the bathroom sliding door so that the runner can run freely. When I got in and out, I was worried that my feet would fall on the rails.

[0003] Therefore, conventionally, the rail portion is composed of a plurality of cages, the lower runner of the bathroom sliding door is slidably fitted in the gap between the cages, and the upper surface of the cage is flush with the lower frame. In order to prevent the lower frame from having a step, it has been proposed.

[0004]

However, in the case where rail grooves are formed by means of a cage to prevent a step from being formed in the lower frame, the width of the flat surface portion of the lower frame is reduced, and the inside of the bathroom is reduced. There is a problem that hot water easily flows out of the lower frame to the floor of the dressing room. The present invention has been made in view of the above conventional example, and has a flat bottom portion of a lower frame that is widened to prevent water from flowing out to the undressing room side, and to facilitate entry and exit of the bathroom. It is an object to provide a structure.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a lower frame of a bathroom sliding door 1 between a rail groove for supporting the bathroom sliding door 1 so as to be able to move freely and a floor on the undressing room B side. 9
In the lower frame structure of the bathroom sliding door in which the bathroom sliding door 1 is arranged, the bathroom sliding door 1 is located on the bathroom A side and the bathroom sliding door 2
And a lower runner 11 vertically suspended from the lower end center 2a side of the bathroom side sliding door 2 is slidably inserted into the first rail groove 5 located on the bathroom A side. A lower runner 12 suspended from a position 3b shifted from the lower end center 3a of the room-side sliding door 3 toward the bathroom A is inserted into the second rail groove 6 located on the undressing room B side so as to be able to run freely.
The end of the lower frame 9 on the bathroom A side is hung downward to form the side wall surface 6a of the second rail groove 6 on the undressing room B side, and the undressing room side is located above the flat surface portion 6a of the lower frame 9. The sliding door 3 is arranged, and by having such a configuration, the second rail groove 6 can be arranged closer to the lower side of the bathroom side sliding door 2, and the flat surface portion 9 a of the lower frame 9.
Can be formed to be wide, so that water can be prevented from flowing out to the undressing room B side beyond the lower frame 9 as much as possible, and the foot can be placed on the wide flat surface portion 9a to make the bathroom larger. A comes in and out easily.

Preferably, the flat surface portion 9a of the lower frame 9 is gently inclined toward the bathroom A. In this case, water on the flat surface portion 9a of the lower frame 9 flows into the bathroom A, Even though the flat surface portion 9a is formed wide, it is possible to prevent water from collecting on the flat surface portion 9a. In addition, a water return packing 13 arranged in the second rail groove 6 is mounted in the vertical direction of the hanging portion 9b of the lower frame 9 constituting the side wall surface 6a of the second rail groove 6 on the undressing room B side. Mounting portion 14 is provided, and a lower portion of the hanging portion 9b below the packing mounting portion 14 is protruded from the side wall surface 6b of the second rail groove 6 on the bathroom A side to prevent water intrusion. In this case, it is possible to prevent the outflow of the blow-up water from the bottom to the top by the return packing 13, and at the same time, the momentum of the water from below is weakened by the step portion 15, and the return packing 13 is formed. Water can be hardly reached, and the backflow of water can be reliably prevented.
