Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower frame structure of a partition door in a general house or the like, and in particular, to a lower frame of a partition frame such as a sliding door, a folding door and a hinged door provided between a bathroom and a dressing room. It relates to the frame structure.

[0002]

2. Description of the Related Art A lower frame of a door frame provided at an opening between a bathroom and a dressing room is located above the floor of the dressing room in order to prevent hot water used in a washing room in the bathroom from overflowing to the side of the dressing room. Is also a bit high.

However, at the entrance of the bathroom for the physically handicapped, a shallow groove 91 near the entrance is provided so that a severely disabled person can easily enter and exit the bathroom with a wheelchair when taking a bath.
And a deep groove 92 near the washing place is provided over the entire length of the entrance, a pair of right and left hanging walls 94 are provided on the upper surface of the shallow groove 91 on the lower surface of the inclined piece 93, and a guide rail is provided on the upper surface. Are formed at equal intervals, and the upper edges thereof are fixed so as to be substantially flush with the floor surfaces of the undressing room 96 and the washing place 97. A hole 98 is formed, and hot and cold water that has entered between the ridges 95 flows through the through hole 98 on the upper surface of the inclined piece 93 and is discharged toward the deep groove portion 92 (FIG. 11). reference).

[0004] A lower frame 101 in an opening frame provided in an opening between a bathroom and a dressing room, which is another prior art, has an auxiliary lower frame 102 on the upper side of the lower frame 101 and an inner edge 103 on the bathroom side. , Rising pieces 104 are formed between them, and horizontal planes 105, 1 of substantially the same height
The space formed between the rising piece 104 and the portion of the lower frame 101 rising toward the interior edge 103 is a drain groove 107 for draining water.

A drain hole 108 is provided below the auxiliary lower frame 102, and a drain hole 109 is also provided below the rising piece 104. Therefore, even when a person passes over the lower frame with a wet body and water drips, the water dripping on the upper surface of the lower frame 101 flows down into the guide groove 110 or the drain groove 107 and quickly passes through the drain holes 108 and 109. It flows out to the bathroom side (see FIG. 12).

However, in the conventional drainage structure of the lower frame forming the opening frame, when a large amount of overflow water or the like from the bathtub is generated in the bathroom in the bathroom, there is a possibility that the water will flow backward from the drainage hole of the lower frame of the fitting. In addition, when this fitting lower frame is used in a living room or the like provided with a balcony, there is a possibility that rainwater may enter the living room from the drain hole in the case of rain accompanied by a cross wind.
