DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom door, and more particularly to a bathroom door provided with a retractable water stop plate on the floor below the door.

[0002]

2. Description of the Related Art The floor of a bathroom washing area is generally one step lower than the floor of a dressing room so that hot water does not leak to the dressing room side because bathers wear hot water to wash their bodies. Or a sill frame of sufficient height was provided between them.

[0003] However, if there is such a step at the entrance of the bathroom, it is inconvenient and dangerous for an elderly person or a person who has difficulty walking to enter and exit because of taking a bath.
Bathroom units having a sufficient drainage function by a combination of a sliding door or a triple sliding door and a drainage tub are commercially available (particularly not shown).

[0004]

However, since the door of the bathroom unit as described above is a sliding door or a triple sliding door, a space with an opening width for drawing in the door is required, and a sufficient margin in area is required. In the bathrooms, dressing rooms and washrooms of general houses, which are relatively difficult to take, the degree of freedom in designing the floor plan was low and it was inconvenient.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and it is possible to reduce the step at the lower part of the door when the door is opened and closed and to close the door in the relatively small space. Sometimes, the purpose is to provide bathroom door means having a sufficient water leakage prevention function to the dressing room side.

[0006]

For this reason, in the present invention, a single-opening door provided between a bathroom and a dressing room and a door frame thereof are provided, and a drain groove is provided below a lower frame of the door frame.
A water blocking plate pivotally supported on both sides of the lower frame over the opening width of the door frame and having a curved cross section continuous from the middle of the depth of the drainage groove to the upper surface of the bathroom floor, and a lower end of the door; A water shut-off plate driving means for abutting on the water shut-off plate and rotating the water shut-off plate upward together with the rotation of the door in the closing direction on a door rotating shaft that is vertically installed and fixed to the door. Thus, the above object is achieved.

[0007]

With the above-described door structure, when the door is opened, the water stop plate is lowered by its own weight into the drainage ditch so that the upper edge of the water stop plate is on the bathroom floor surface, and the lower portion of the door is substantially closed. When the door is closed, the water stop plate is slidably driven by the water stop plate drive arm rotating together with the door rotation shaft, and the water stop plate is rotated around the water stop plate rotation axis. The door pivots upward to close the lower end of the door to the undressing room side, thereby preventing water leakage from the bathroom side.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments.
FIGS. 3 (e) and 3 (f) are perspective views of two examples of the bathroom door according to the present invention. The front side represents the undressing room side, and the opposite side represents the bathroom side. 1 (a) and 1 (b) and FIG.
(C) and (d) show a detailed vertical sectional view and a plan view of a circle A (common to (e) and (f)) in FIG. 3 in the door open state and the closed state, respectively.

(Structure) In FIG. 3, reference numeral 1 denotes a one-piece type, and 2 denotes a two-fold type single-sided door, which opens and closes toward a bathroom centering on a rotation shaft 4 of one upper and lower frame portion of a door frame 3 respectively. obtain.

In FIG. 1, reference numeral 5 denotes a floor of a dressing room, and reference numeral 6 denotes a floor of a bathroom having no steps. Drainage grooves 7 are formed in the lower portion of the lower frame of the door frame 3, and the openings thereof are laid on the part of the bathroom floor surface and on the extensions thereof, respectively, with slats 8 a and 8.

A drain groove 7 extends over both sides of the lower frame of the door frame 3.
A water stop plate 9 having a substantially 1/4 arc-shaped cross section extending from the middle depth to the bathroom floor 6 is pivotally supported on both sides of the lower frame by a rotating shaft 10 via an arm 11, and A smooth sliding edge 9a having a rounded shape at the lower end side of the / 4 arc-shaped cross section
However, a strip-shaped stopper edge 9b is formed on the upper end side,
When the door 1/2 (hereinafter, only 1) is opened, the water stop plate 9 hangs down by its own weight, and the stopper edge 9b is locked on substantially the same plane as the glass 8.

On the other hand, a door rotating shaft 4 is erected and fixed on the lower surface of the door 1, and a lower end is pivotally supported on a bottom portion of the drain groove 7, and a lever-shaped water stop plate driving arm is provided on the upper portion thereof. 12 is fixed at the position shown in the figure, and is configured to rotate simultaneously with the door 1.

(Operation) Next, an operation when the door is closed will be described with reference to FIG. When the door 1 is rotated to close the door 1, as shown in FIG.
Also rotates in the direction of the dotted line arrow, abuts against the sliding edge 9a of the water stop plate 9, and rotates upward while rotating while pushing up while sliding, as shown in FIG. When the stopper edge 9b abuts on the side of the undressing room of the door 1 to close the gap at the lower part of the door 1 and prevent water from leaking from the bathroom side, when the door 1 is opened again, the water stop plate 9 As a result, it hangs down inside the drain groove 7, and the step is eliminated.

The means for driving the water stop plate 9 in the vertical direction in this embodiment is not limited to the drive arm 12 alone.
Other methods are acceptable.

[0015]

As described above, according to the present invention,
A water-stop plate mechanism that protrudes and retracts from the lower part of the door frame in conjunction with the rotation of the one-sided door prevents water leakage from the bathroom side to the dressing room side when the door is closed, and is necessary for elderly people etc. In this case, it is possible to eliminate the step between the two chambers when the door is opened.
