2. Description of the Related Art Conventionally, as disclosed in Japanese Patent Laid-Open No. 10-140947, there is known a water shut-off device for a door which can seal a gap generated under a bathroom door in accordance with its closing operation. . The water stop device for the door is shown in FIGS.

And packing members 46 and 47 for sealing the gap between the lower edge of the door panel 2 and the lower frame portion 3 of the fixed support frame 1. In this case, one packing member 46 is the door panel 2
Is fixed to the lower frame of the fixed support frame 1, and the other packing member 47 is fixed to the lower frame portion 3 of the fixed support frame 1.

In the water shut-off device for the door, the door panel 2 is attached to one side frame of the fixed support frame 1 by a gravity hinge 48.
Since the door panel 2 is attached and supported through the gap, the gap generated below the door panel 2 when the door panel 2 is closed is sealed. That is, when closing the door panel 2, as shown in FIGS.
As shown in FIG. 5, the door panel 2 is lowered by the action of the gravity hinge 48, and the packing members 46 and 47 sandwiched between the lower frame portion 3 of the fixed support frame 1 and the lower frame of the door panel 2 are compressed and elastically deformed. However, as a result, the watertightness between the two is realized. On the contrary, when the door panel 2 is opened, the door panel 2 rises due to the action of the gravity hinge 48 and the frictional resistance due to the compressed packing members 46, 47 decreases, and the door panel 2 can be opened with less resistance. It is possible.

Further, in this case, the lower frame portion 3 of the fixed support frame 1
Has an upper surface continuous with the floor surfaces on both sides thereof, and has a so-called barrier-free structure without steps, which is an effective water shut-off device for the door. That is, in recent years, when the upper surface of the lower frame portion 3 of the fixed support frame 1 is raised and a step is provided between the floor surface on both sides of the lower frame portion 3, there is a risk that the foot may be caught on the step and trip over. To prevent this from happening, it is desired that barriers be eliminated by eliminating steps at the entrance and exit of the bathroom. Here, in particular, a water shut-off device for a door, which can seal a gap generated below the door panel 2 with its closing operation,
This is effective because it does not hinder the opening / closing operation of the door panel 2.

However, in the above-mentioned conventional technique, the packing members 46 and 47 are compressed by the weight of the door panel 2, and the packing members 46 and 47 are compressed by the weight of the door panel 2. There has been a problem that the elastic pressure alone cannot provide a sufficient sealing pressure for maintaining and securing the waterproofness. For example, packing member 4
If the anti-deformation pressure of 6, 47 is small, the packing members 46, 47
Was likely to cause water leakage because it was deformed due to aging, or was deformed due to a large amount of water overflowing from the bathtub or the water pressure of the shower or the like. Further, in order to satisfy the sealing pressure, it is necessary to increase the weight of the door panel 2, and in this case, there is a problem in that it is difficult to open and close the door panel 2 manually.

The present invention has been made in order to solve the above-mentioned problems in the prior art. The problem is to apply a sealing pressure to the gap between the lower edge of the door panel and the lower frame of the fixed support frame. Improves the waterproofness, and
The sealing pressure is to provide a water shut-off device for a door that can be easily obtained with the closing operation of the door panel.

Further, the operation pump 5 is built in the upper part of the vertical frame portion 10 on the side of which the door panel 2 is pivotally supported, and the operation pump 5 is vertically long and has a bellows shape so as to be extendable and contractible in the thickness direction of the door panel 2. Has been formed.
Then, as shown in FIG. 4, one end of the operation pump 5 in the extension and contraction direction is fixed to the inner side surface of the vertical frame portion 10, and the operation piece 11 serving as the interlocking mechanism 6 is attached to the other end thereof to attach the same to the vertical frame portion. It is projected from 10 to the back.

As shown in FIG. 1, a plurality of the operation pieces 11 are arranged in the vertical direction of the operation pump 5, and each operation piece 11 is arranged.
Is a door stop 25 projecting on the inner surface of the side frame portion 12 of the fixed support frame 1.
The pump 5 of the same operation is compressed by being brought into contact with. That is, as shown in FIG. 4, the door panel 2 is closed so as to go through each process in the order of FIGS. Is pushed into the vertical frame portion 10 and the operating pump 5 is elastically deformed and compressed in the thickness direction of the door panel 2 via the operating piece 11. In this case, the handle 7 attached to the vertical frame 10 on the side opposite to the side where the door panel 2 is pivotally fixed.
The door is closed with the action piece 11 at that time.
The operation piece 11 is smoothly pushed into the vertical frame portion 10 because the portion contacted with is formed into an inclined curved surface.

As described above, when the working pump 5 is compressed, the air in the working pump 5 is injected into the packing member 4. The closed tube which becomes the packing member 4 is a bag-shaped member which is made of a flexible and elastic resin material and is expandable and contractible, and is made of, for example, silicone rubber, urethane,
It is made of fluororubber, nylon, polyethylene, polypropylene or the like. Further, the sealing tube serving as the packing member 4 extends from the lower frame portion 9 of the door panel 2 to the lower outer side of both vertical frame portions 10 and is arranged in a substantially U-shape. The packing part 4a and the packing parts 4b on both sides are integrally formed so as to be continuous.

The operating pump 5 and the packing member 4 are connected to each other via a piping 24 with a throttle. At that time, the lower end portion of the operating pump 5 and the upper end portion of one packing portion 4b of the packing member 4 are connected. However, in the vertical frame portion 10 on the side of which the door panel 2 is pivotally supported, they are connected to each other through the pipe 24 with a throttle. In this case, even if the operation pump 5 is compressed, the air does not immediately move to the packing member 4, but the air gradually moves through the piping 24 with a throttle, and the operation pump 5
The air moves to the packing member 4 until the air pressures in the bag and the packing member 4 are in equilibrium with each other (the air pressure in the bag here is in the range of 1.5 to 5 atm). The air is injected smoothly and reliably.

The upper end of the wire 26 is connected to the handle 7 attached to the vertical frame portion 10 on the side opposite to the side where the door panel 2 is axially fixed, and the lower end of the wire 26 is vertically connected. Packing portion 4b of the packing member 4 attached to the frame portion 10

That is, in this case, when the door panel 2 is opened, the air escape hole 27 of the exhaust plug 8 can be easily opened by rotating the handle 7 to open the packing member 4. The air inside is the same as the air escape hole 27.
The packing member 4 is contracted and deformed by its elastic restoring force. In addition, as the door panel 2 is opened, the compressed state of the operation piece 11 of the operation pump 5 is released, and the packing member 4 is contracted and deformed.
And the sliding contact resistance between the fixed support frame 1 and
The door panel 2 can be opened smoothly without resistance.

Further, as shown in FIG. 6A, the fixed support frame 1
The inner peripheral surfaces of the corner inner corners of the lower frame portion 3 and the side frame portion 12 are formed in an R shape, and the gap dimension X between the inner peripheral surface and the outer peripheral surface of the door panel 2 becomes uniform. As a result, the compression allowance of the closed tube serving as the packing member 4 becomes uniform, and the water blocking performance at the corner portion is improved. That is, FIG.
As shown in (b), the lower frame portion 3 and the side frame portion 12 of the fixed support frame 1
If the inner peripheral surface of the inner corner portion of the corner is a right angle, the compression allowance of the sealing tube serving as the packing member 4 is insufficient at the corner portion, and a gap is generated, so that the water stopping performance cannot be ensured. Is solved. If it is difficult to form the inner peripheral surface into an R shape in manufacturing, the inner peripheral surface may be formed in a polygonal shape.

Further, as shown in FIG. 7, a low hardness elastic body 29 is integrally formed on the outer surface of the closed tube which becomes the packing member 4, and the low hardness elastic body 29 is formed into the R-shape fixed support frame 1. It may be adapted to correspond to the inner peripheral surface of the inner corner portion of the corner. In this case, as the low-hardness elastic body 29, a material such as urethane rubber, silicone rubber, or fluororubber having a shear hardness of RA60 or less is used, whereby the fixed support frame 1
Even if a foreign substance having fine irregularities is caught between the door panel 2 and the door panel 2, the watertightness can be maintained without any clearance. Even if the low-hardness elastic body 29 is integrated on the inner peripheral surface side of the inner corner portion of the fixed support frame 1, it is possible to similarly prevent the water-stop performance from being reduced.

Further, as shown in FIG. 8, if the corner portion of the door panel 2 is also formed in the R shape so as to correspond to the inner peripheral surface of the corner inner corner portion of the fixed support frame 1 having the R shape,
A more uniform compression margin is ensured in the closed tube that serves as the packing member 4, and the water blocking performance is further improved. Further, in this case, the sealing pressure is not locally applied to the sealing tube which becomes the packing member 4 at the corner portion of the door panel 2, so that the sealing tube is prevented from being damaged.

Further, as shown in FIG. 9, even if the inner peripheral surfaces of the corner inner corners of the lower frame portion 3 and the side frame portion 12 of the fixed support frame 1 are right-angled, the right inner peripheral surface By integrally forming the substantially triangular corner material 30 corresponding to the above, on the outer surface of the sealed tube serving as the packing member 4, the compression allowance of the sealed tube is ensured uniformly and the sealing pressure is also applied uniformly. As a result, the water stopping property at the corner portion is further improved. In this case, the corner member 30 is made of the same kind of silicone rubber as the closed tube, can be welded to the outer surface of the closed tube, and can be fixed and integrated by two-color molding.

Further, as shown in FIG. 10, even if the inner peripheral surfaces of the inner corners of the lower frame portion 3 and the side frame portion 12 of the fixed support frame 1 are right-angled, a sealed tube serving as the packing member 4 is formed. R
By attaching and fixing the substantially triangular corner material 30 along the outer surface of the shape to the right-angled inner peripheral portion of the fixed support frame 1, the compression allowance of the closed tube is secured uniformly and the closing pressure is also increased. Since the water is evenly applied, the waterproof property at the corner portion is further improved. In this case, even if there is a positional deviation between the fixed support frame 1 and the door panel 2, the sealing pressure is evenly applied, and the waterproofness is further improved. At this time, if the corner material 30 is made of a material having a high hardness such as high hardness silicon rubber, the closed tube serving as the packing member 4 easily maintains its shape, and the waterproofness is secured. Further, when the corner member 30 is attached and fixed to the fixed support frame 1, the connecting piece portion 31 protruding from the corner member 30 is attached to the fixed support frame 1.
It can be easily attached by fitting and welding in the coupling hole 32 formed in.

The sealed tube serving as the packing member 4 may be welded to the lower surface of the lower frame portion 9 of the door panel 2, screwed, or simultaneously fixed and integrated by simultaneous molding. . Further, as the shape of the sealed tube which becomes the packing member 4 and the mounting form thereof, various forms can be adopted as shown in FIG. For example, as shown in FIG. 11 (a), a closed tube having a substantially circular cross-section serving as the packing member 4 may be fixed to the flat lower surface of the lower frame portion 9 of the door panel 2 as it is, but as shown in FIG. 11 (b). As shown, a recess 33 may be formed in the lower surface of the lower frame portion 9 and the same sealing tube may be fixed to the recess 33 by biting into the recess 33. In this case, the sealing tube is stable. It is held and fixed in the state.

Further, as described above, in the form in which the closed tube serving as the packing member 4 is held and fixed in the recess 33 formed in the lower surface of the lower frame portion 9 of the door panel 2, FIG.
As shown in FIG. 2, the closed tube may have a two-layer structure having an inner core layer 34 made of urethane rubber and an outer surface layer 35 made of silicon rubber having RA60 or less and having a low hardness. Further, as shown in FIG. 11 (d), the sealed tubes to be the packing member 4 may be doubly arranged and fixed in parallel.
As shown in (e), a closed tube having a plurality of hollow holes 36 may be used.

Therefore, in the water shut-off device for a door of the embodiment, the packing member 4 is formed of a flexible and expandable / deformable closed tube, and air is injected into the closed tube to expand and deform the packing member 4. Since the operating pump 5 to be operated is connected to the packing member 4 via the piping 24 with a throttle, the packing member 4 is surely expanded and deformed when air is injected by the operating pump 5, and the packing member 4
As a result, a sufficient sealing pressure is applied to the gap between the lower surface of the lower frame portion 9 of the door panel 2 and the upper surface of the lower frame portion 3 of the fixed support frame 1, so that the waterproof performance can be improved by the high sealing pressure.

Moreover, since the operation pump 5 is compressed by the closing operation of the door panel 2 through the interlocking mechanism 6 so that the air is injected into the closed tube, the closing operation of the door panel 2 is performed. Accordingly, the packing member 4 is expanded and deformed, and the sealing pressure can be easily obtained by the packing member 4. That is, by closing the door panel 2, the sealing pressure is maintained high and secured, and the energy saving by human power (power to close the door panel 2) by human power can easily improve the water blocking performance by the high sealing pressure.

Further, in this case, since the closed tube is provided with the exhaust plug 8 which is opened by the turning operation of the handle 7 attached to the door panel 2, when the door panel 2 is opened, By rotating the handle 7 to open the exhaust plug 8 to discharge and remove air from the closed tube, the closing pressure is easily released, and the door panel 2 can be opened smoothly with less resistance. .

Further, in the water shut-off device for a door of the embodiment, since the lower frame portion 9 of the door panel 2 is provided with the sealing tube serving as the packing member 4, the packing member 4 moves together with the door panel 2. Therefore, it does not become an obstacle on the lower frame portion 3 of the fixed support frame 1, and the occurrence of a step on the upper surface of the lower frame portion 3 is prevented. Moreover, since the operation pump 5 is built in the vertical frame portion 10 of the door panel 2, the operation pump 5 is integrated with the door panel 2 together with the packing member 4 so that the operation pump 5 fits neatly and the construction becomes easy. Will be easy to handle.

Further, in this case, since the sealing tube serving as the packing member 4 is extended to the lower outer side of both vertical frame portions 10 of the door panel 2 and arranged in a substantially U-shape, the bathroom-side floor surface 14 Even when the water level of the water that collects above and leaks to the floor surface 15 on the side of the dressing room becomes higher than the lower edge of the door panel 2, the water stopping property is ensured. Moreover, since the operating pump 5 is built in the upper portion of the one vertical frame portion 10, the operating pump 5 can be compactly housed in the upper portion of the vertical frame portion 10 without hindering the extension of the packing member 4.

Further, in the water shut-off device for a door of the embodiment, an operating piece is attached to the vertical frame portion 10 of the door panel 2 as the interlocking mechanism 6.
By projecting 11 and the operation piece 11 slidingly contacting the door stop 25 formed on the side frame portion 12 of the fixed support frame 1 with the closing operation of the door panel 2 and being pushed into the vertical frame portion 10, Since the operating pump 5 is elastically deformed and compressed by the operating piece 11, the operating pump 5 is reliably compressed by the operating piece 11 pushed in with the closing operation of the door panel 2, and the operating pump 5 is compressed. With the packing member 4 which is sufficiently expanded and deformed by 5, a higher sealing pressure can be obtained.

Further, in the water shut-off device for a door of the embodiment, the operation frame 5 is built in the vertical frame portion 10 on the side where the door panel 2 serving as a swing door is pivotally supported, and the vertical frame portion is provided.
Since the operating piece 11 as the interlocking mechanism 6 is provided on the protrusion 10, the door closing force is given by pushing the handle 7 located on the side opposite to the side on which the coaxial support is fixed. Even if the
