DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door structure of a unit bus, and more particularly to a door structure in which a lower frame of a door frame and a lower stile of a door body are devised.

[0002]

2. Description of the Related Art A conventional unit bus door structure is shown in FIG.
As shown in FIG. 4 and FIG. 4, a washing place 101 and a bathtub place 102 are formed on the floor pan 100, and the bathtub place 10 is formed.
2, a bathtub 103 is installed, and a door 200 is mounted on a predetermined side of the washing place 101. The floor pan 100 is supported at a predetermined height on a floor slab 105 by support legs 104, and a lower frame 201 of a door frame is installed on one side of the washing room 101. This lower frame 201 is the outer frame 2 on the outside of the bathroom.
The lower frame 201 is integrally formed with the lower side of the lower frame 201, and the lower frame 201 is provided one step lower than the outer frame 202. It is supposed to. Also,
Barrier-free design with an entrance step of 20 mm or less. As another conventional example, there is also known an example in which a lower frame 201 as shown in FIG. 5 is used and the shape of the seal member 204 is changed.

[0003]

In the conventional structure on the lower side of the door, if hot water overflows when entering the bathtub 103, the overflowing water overflows into the washing place 101 and the lower frame 20 does not.
When trying to escape from the outside, only the seal member 204 functions to prevent leakage to the outside. In addition, because of the barrier-free design in which the entrance and exit steps are reduced to 20 mm or less, when the bathtub 103 is filled with hot water, the amount of hot water that overflows the washing area 101 is sufficient to leak out of the seal member 204. Thus, it was not possible to sufficiently prevent leakage with the seal member 204 alone.

Accordingly, an object of the present invention is to provide a door structure of a unit bath which can prevent overflow water from leaking out of a bathroom even in a barrier-free design in which a step height is reduced.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a door frame lower frame on a predetermined side of a unit bath washing area, and a lower stile of the door body closes the door body. In a door structure of a unit bath which sometimes comes into contact with a seal member provided on a lower frame, a standing wall formed by bending downward from one side of a lower side of an outer frame fixed to the outside of the bathroom, and A lower frame is constituted by an inclined wall which is inclined so as to gradually descend toward the bathroom, and an extending portion which is stepped down by one step from the inclined wall and extends toward the bathroom, and an outer frame is provided outside the bathroom of the lower stile. An engaging ridge is provided at a position higher than one lower side of the lower side, a seal member having an upper end portion engaging with the engaging ridge is attached to the upright wall, and the door is closed on the bathroom side lower surface of the lower stile. Packing material whose lower end contacts the step One in which mounted as hanging.

[0006]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an enlarged cross section of a lower structure of a door. A lower frame 3 is provided on a predetermined side of a washing place 1A of a floor pan 1 of a unit bath via a sealing material 2, and a door body 4 is provided. The lower stile 5 contacts the seal member 6 provided on the lower frame 3 when the door body 4 is closed, so that the sealing property is maintained at the contact point. An upright wall 3A formed by bending downward from one side of a lower side 7A of the outer frame 7 fixed to the outside of the bathroom; an inclined wall 3B inclined so as to gradually descend from the lower end of the upright wall 3A toward the bathroom; The lower frame 3 is composed of an extension 3D that is lowered by one step from the inclined wall 3B by a step 3C and extends toward the bathroom. An engagement ridge 5A is provided on the outside of the bathroom of the lower stile 5 at a position higher than one side of the lower side 7A of the outer frame 7. The upper end of the seal member 6 is engaged with the engagement ridge 5A when the door body 4 is closed. Further, the lower stile 5 is attached to the lower surface of the bathroom side of the bathroom so as to suspend the packing material 8 whose lower end contacts the step 3C when the door is closed.

FIG. 2 is a cross section showing the outer frame 7 and the lower frame 3.
A groove 30 for attaching the lower end of the seal member 6 is formed in the upright wall 3A. In addition, the upper side of the step portion 3C that is in contact with the lower end side of the packing material 8 is formed so as to slightly protrude toward the bathroom.

[0009] The bath is filled with hot water in a bathtub, and the hot water overflows into the washing area 1A, that is, FIG.
In this case, even if the water level of the hot water that has overflowed beyond the position where the engagement ridge 5A and the upper end of the seal member 6 are engaged is high, the hot water that has overflown is removed by the packing material 8 at the step 3C. At 1, it is prevented that the hot water overflows out of the bathroom, that is, in the left hand direction, and the hot water overflowing from this seal portion enters the space formed by the lower stile 5 and the lower frame 3, and further engages with the seal member 6. Since there is an engagement point of the abutment ridge 5A, the pressure of the overflowing hot water is insufficient to further overflow the seal location to the outside, and the overflow is being drained from the drain hole of the washing place 1A. Will not leave.

The outer frame 7, the lower frame 3, and the lower stile 5 are formed of a material such as an aluminum alloy, and the seal member 6 and the packing material 8 are preferably made of vinyl chloride, silicon, or the like. The door frame is formed by integrally forming an outer frame 7 on a frame body surrounding the door body 4 with a vertical frame (not shown) and an upper frame (not shown) on both sides of the lower frame 3. ing.

[0011]

As described above, according to the present invention, an upright wall bent downward from one side of a lower side of an outer frame of a door frame fixed to the outside of the bathroom, and a lower end of the upright wall to the bathroom. The lower frame is composed of an inclined wall inclined so as to gradually descend toward the bathroom, and an extending portion extending one step downward from the inclined wall to the bathroom side, and the lower side of the outer frame on the exterior side of the bathroom in the lower stile. An engaging ridge is provided at a position higher than one side of
A seal member having an upper end portion that engages with the engaging ridge is attached to the upright wall, and a packing material is attached to the lower surface of the lower stools on the bathroom side so that the lower end side thereof comes into contact with the step portion when the door is closed. The height from the seal point where the material comes into contact with the step to the seal point where the upper end of the seal member engages with the engaging ridge can be sufficiently high, and therefore a barrier-free design with a small step difference at the entrance and exit is used. Even if the hot water overflows from the sealing portion made of the packing material, it can be prevented from overflowing from the portion engaging with the engaging ridge of the seal member.
