Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door water stop member that is attached to a gap around a door to prevent water from entering inside the door, and a door water stop method using the door water stop member.

In recent years, flood damage due to torrential rain has frequently occurred in various parts of Japan. When a water area such as a river overflows, surrounding buildings are flooded, causing great damage. For this reason, in areas where flooding is expected, when a heavy rain flood warning is announced or is expected to be issued, measures are taken to seal gaps in buildings (gaps around doors) with adhesive tape, etc. ing. As a result, even if the surroundings of the building are flooded, the water can be prevented from entering the building.

However, if the adhesive tape pasted on the gap of the door has wrinkles, there is a risk that water will enter through the wrinkled portions. In some cases, the pressure of water entering the wrinkles may cause the adhesive tape to peel off. For this reason, the adhesive tape must be neatly pasted along the door gap without wrinkles, but this work is surprisingly time-consuming. Moreover, when the adhesive tape stuck in the gap is peeled off after the heavy rain flood warning is safely lifted, there is a risk that the paint on the door or wall will be peeled off at this time.

By the way, packings disclosed in Patent Document 1 and Patent Document 2 have been proposed so far for closing the gap around the door. These packings are pre-installed around the door before use.

Japanese Utility Model Laid-Open No. 59-185397 JP-A-2000-130921

However, the packings of Patent Document 1 and Patent Document 2 are both for maintaining the airtightness and sound insulation inside and outside the door, and are not intended for the water pressure when the door is flooded. Therefore, when the door is flooded, water may enter through the gap between the packing and the door or between the packing and the door frame. In order to prevent this, if the packing of Patent Document 1 or Patent Document 2 is made robust, there is a risk that the behavior of the door will be affected, such as making it difficult to open and close the door, and that the appearance of the door will be bad. There is also

Moreover, both the packings of Patent Document 1 and Patent Document 2 are attached in advance around the door. For this reason, it is necessary to prepare the door, door frame, etc. in advance so that the packing can be attached. Therefore, it is difficult to use for existing doors. Furthermore, the packings of Patent Document 1 and Patent Document 2 are attached to inconspicuous places such as doors and door frames, so even if they deteriorate due to aging, they will continue to be used without noticing it. function may not be exhibited. In addition, even if the deterioration can be noticed, it is difficult to remove and install, and replacement requires time and effort.

The present invention was made to solve the above problems, and when flooding is expected, by temporarily attaching it to the gap around the door, it is possible to exhibit a sufficient water stopping function. To provide a waterproof member for a door that can be It is another object of the present invention to provide a door waterproof member that is easy to install and remove. It is another object of the present invention to provide a method for water stopping a door using this door water stopping member.

The above issues are
A water stop member for a door that prevents water from entering the inside of the door even when the outside of the door is flooded by attaching it along a gap around the door,
a belt-shaped water stop part that closes the gap from the outside of the door;
A water stop member for a door, characterized by comprising: a press-fitting convex portion that protrudes from an inner surface of the band-shaped water stop portion and is held in the gap by being press-fitted into the gap from the outside of the door. solved by providing

The door waterproof member of the present invention includes a band-like waterproof part that seals a gap from the outside of the door. When the door is flooded (when the outside of the door is flooded up to the height of the door; the same shall apply hereinafter), this strip-shaped water stop is strong against the door and door frame due to the pressure of the water existing outside the door. It will be in a pressed state. Therefore, when the door is flooded, the strip-like water-stopping portion comes into closer contact with the door, the door frame, etc., and the water-tightness of the door water-stopping member is further enhanced. Therefore, even when the door is flooded, the water stopping function can be fully exhibited.

In addition, the door waterproof member of the present invention is not to be attached to the door or the like in advance, but is temporarily attached to the periphery of the door only when necessary (when flooding is expected, etc.). It is supposed to be used. Therefore, it can be used for existing doors. In addition, the behavior and appearance of the door during normal operation (when the waterproof member for the door is not used) does not deteriorate. Furthermore, even if the door water-stop member has deteriorated due to aging or the like, it can be easily noticed, and the deteriorated door water-stop member can be prevented from being used. Therefore, it is possible to prevent the occurrence of a situation in which the door waterproof member cannot perform its function (the function of preventing water from entering) when the door is flooded. Furthermore, even when the door waterproof member needs to be replaced due to deterioration or the like, the replacement work can be easily performed.

In the door waterproof member of the present invention, the press-fitting protrusion is not particularly limited in its specific structure. It is preferable to have a branch convex portion that protrudes in the width direction of the gap. As a result, the press-fitting projection can be easily elastically deformed and can be easily press-fitted into the gap around the door, and at the same time, can be structured to be difficult to slip out of the gap (easy to be held in the gap).

In the water stop member for a door of the present invention, when the press-fitting protrusion is composed of the body protrusion and the branch protrusion, the main body protrusion may It is preferable to form a cross-sectional triangular shape that narrows from the side toward the tip (the end on the side opposite to the base end). In addition, the branch convex portion is formed to have a triangular cross section that narrows from the base end (the end connected to the main body convex portion) toward the tip (the end opposite to the base end). is also preferred.

In this way, by thickening the base (basal end side) of the press-fitting convex portion while thinning the distal end side of the main convex portion and the branch convex portion, elastic deformation of the main convex portion and the branch convex portion is facilitated. It is possible to impart rigidity to the main body convex portion and the branch convex portion to such an extent that they do not easily fall down while maintaining the rigidity. Therefore, when the press-fitting protrusion is press-fitted into the gap around the door, the press-fitting protrusion can be firmly held in the gap.

In the waterproof member for a door of the present invention, when the press-fitting convex portion is composed of the main convex portion and the branch convex portion, the branch convex portion is arranged at a predetermined interval from the proximal end side to the distal end side of the main convex portion. It is preferable that the branched convex portion at a step closer to the base end side of the main body convex portion has a larger protrusion amount than the branched convex portion at a step closer to the distal end side of the main body convex portion. This makes it easier to press-fit the door waterproof member into the gap around the door. The waterproof door member of the present invention has a longitudinal shape so that it can be arranged along the gap around the door. If only the first few centimeters along the line are press-fitted into the gap, the rest of the section can be press-fitted into the gap simply by pressing the outer surface of the band-shaped water stop portion with a finger.

In the water stop member for a door of the present invention, the press-fit projection may be provided at the widthwise center of the strip-shaped water-stopping portion, but it is also preferable to provide it eccentrically at a location deviated from the widthwise center of the strip-shaped water-stopping portion. . This is because the band-shaped waterproofing part has a width wider than the gap to which it is attached, and is attached to the outer surfaces of both sides of the gap (the door and the door frame) so as to cover the gap from the outside. However, there may not be enough space on both sides of the gap to fit the water stop strip. In this case, there is a risk that the strip-like water-stopping part will interfere with the surrounding parts and float up from the outer surface of the door or the like, allowing water to enter from that part. To prevent a band-like water-stopping part from interfering with surrounding parts by making the shape of a water-stopping member for a door asymmetrical by providing it at a position shifted from the water-stopping member, and devising how to install the water-stopping member for a door. This is because

As described above, the present invention provides a water-stopping member for a door that can exhibit a sufficient water-stopping function by temporarily attaching it to the gap around the door when flooding is expected. becomes possible. Moreover, it is also possible to provide a door waterproof member that is easy to attach and detach. Furthermore, it is also possible to provide a door water stopping method using this door water stopping member.

A preferred embodiment of the waterproof door member of the present invention will be described more specifically with reference to the drawings. Four embodiments (from the first embodiment to the fourth embodiment) will be exemplified below to describe the door waterproof member of the present invention. However, the technical scope of the door waterproof member of the present invention is not limited to these embodiments. The waterproof member for a door of the present invention can be appropriately modified within the scope of the invention.

1. Door Water Stop Member of First Embodiment First, the door water stop member of the first embodiment will be described. 1 to 7 show a door waterproof member 10 according to a first embodiment. 1 is a perspective view of the door water-stopping member 10, FIG. 2 is a front view of the door water-stopping member 10, FIG. 3 is a rear view of the door water-stopping member 10, and FIG. 5 is a right side view of the door waterproof member 10, FIG. 5 is a left side view of the door waterproof member 10, FIG. 6 is a plan view of the door waterproof member 10, and FIG. 2] is a bottom view of the door waterproof member 10. [FIG.

FIG. 8 is a view showing the state of the door 20 to which the door waterproof member 10 is attached, viewed from the outside. As shown in FIG. 8, there is a gap D around the door 20 of the building. The gap D is closed by attaching the same. As a result, even if the outside of the door 20 is flooded due to water damage or the like, the water can be prevented from entering the inside of the door 20 through the gap D, and damage can be minimized. FIG. 9 is a perspective view showing how the door waterproof member 10 is attached to the gap D of the door 20 (the appearance of the outer surface of the door 20). FIG. 10 is a view of a state in which the door waterproof member 10 has been attached to the gap D of the door 20 as viewed from the outside of the door 20. As shown in FIG. FIG. 11 is a cross-sectional view of a state in which the door waterproof member 10 is attached to the gap D of the door 20, cut along a plane perpendicular to the longitudinal direction of the door waterproof member.

Thus, the door waterproof member 10 of the first embodiment is used by temporarily attaching it to the gap D around the door 20 only when it is necessary (when flooding is expected, etc.). It has become. Therefore, it can be used for the existing door 20 as well. Moreover, the behavior and appearance of the door 20 in the normal state (when the door waterproof member is not used) do not deteriorate. Furthermore, even if the door waterproof member 10 deteriorates, it can be easily noticed. Furthermore, even when the door waterproof member 10 needs to be replaced due to deterioration or the like, the replacement work can be easily performed.

The door water stop member 10 of the first embodiment includes a belt-like water stop portion 12 and a press-fit projection 11, as shown in FIG. The door waterproof member 10 has a longitudinal shape (elongated shape) and can be fitted along the gap D ( FIG. 9 ) around the door 20 . The door waterproof member 10 is made of a waterproof elastic material (rubber). The strip-shaped waterproofing portion 12 and the press-fitting convex portion 11 may be separately molded and combined later, but are usually integrally molded (extrusion molding, injection molding, etc.). In the door waterproof member 10 of the first embodiment, the whole including the band-shaped waterproof member 12 and the press-fitting protrusion 11 is integrally molded by extrusion molding.

The length (the length along the longitudinal direction; hereinafter the same) of the door waterproof member 10 is not particularly limited. However, if the door water-stopping member 10 is short, a large number of door water-stopping members 10 are required to water-stop the gap D around one door 20 . When a plurality of door water-stopping members 10 are used to stop water in the gap D, water-stopping at the joints of the door water-stopping members 10 can be separately performed with a waterproof adhesive tape or the like. Preferably, the number of joints of the door waterproof member 10 increases as the number of door waterproof members 10 increases. For this reason, the length of the door waterproof member 10 is preferably 30 cm or longer. The length of the door waterproof member 10 is more preferably 50 cm or longer, more preferably 70 cm or longer.

However, if the door waterproof member 10 is too long, it becomes difficult to handle the door waterproof member 10 . In addition, when the door water-stopping member 10 is stored, it is necessary to bend the door water-stopping member 10 such as by winding the door water-stopping member 10. There is also a possibility that it will become peculiar and it will be difficult to perform the work of attaching the door waterproof member 10 to the gap D. For this reason, the length of the door waterproof member 10 is preferably 300 cm or less. The length of the door waterproof member 10 is more preferably 200 cm or less, more preferably 150 cm or less. In the door waterproof member 10 of the first embodiment, the length of the door waterproof member 10 is set to 100 cm.

The type of rubber used for the door waterproof member 10 is not particularly limited, and conventionally known various rubbers can be selected. Rubbers used for the door waterproof member 10 include natural rubber (NR), isoprene rubber (IR), butadiene rubber (BR), styrene-butadiene rubber (SBR), chloroprene rubber (CR), and butyl rubber. (IIR), acrylonitrile butadiene rubber (NBR), hydrogenated acrylonitrile butadiene rubber (HNBR), norbornene rubber (NOR), ethylene-propylene rubber (EPM), ethylene-propylene-diene rubber (EPDM), acrylic Examples include rubber (ACM), fluororubber (FKM), chlorosulfonated polyethylene (CSM), epichlorohydrin rubber, silicone rubber, and urethane rubber. One type of these rubbers may be used alone, or two or more types may be used. Among these rubbers, the door waterproof member 10 of the first embodiment is molded using ethylene-propylene-diene rubber (EPDM). Ethylene-propylene-diene rubber (EPDM) has the advantages of excellent weather resistance and resistance to deterioration.

As shown in FIG. 1, the strip-shaped water stop portion 12 has a strip-like shape. As shown in FIG. 11, the strip-like waterproof part 12 is a part for covering and blocking the gap D from the outside of the door 20. As shown in FIG. Thereby, even if the outside of the door 20 is flooded, the water can be prevented from entering the inside of the door 20 through the gap D. When the door 20 is flooded (when the outside of the door 20 is flooded), the pressure of the water existing outside the door 20 presses the outer surface of the strip-shaped water stop portion 12 strongly inward (Fig. Arrow A ₁ in 11). Therefore, when the door 20 is flooded, the band-like waterproof part 12 is in a state of being in closer contact with the door 20 and the door frame 40 around it, so that the watertightness of the door waterproof member 10 is further enhanced. becomes.

The width W ₁ (FIG. 11) of the strip-shaped water stop portion 12 is set wider than the width W ₀ of the gap D (FIG. 11). A specific value of the width _W1 of the strip-shaped water stop portion 12 is appropriately determined in consideration of the expected width _W0 of the gap D. When it is assumed that the door waterproof member 10 is attached to a gap D with a narrow width _W0 , the width _W1 of the band-shaped waterproof portion 12 is set to about 10 to 20 mm, and the width _W0 is set to a wide width. When it is assumed that the door waterproof member 10 is attached to the gap D, the width _W1 of the band-shaped waterproof member 12 is set to about 20 to 50 mm. In the door water stop member 10 of the first embodiment, the width _W1 of the band-shaped water stop portion 12 is set to 16 mm. The thickness of the strip-shaped water stop portion 12 (the maximum value if the thickness varies depending on the location; the same shall apply hereinafter) is not particularly limited, but is usually set in the range of 1 to 5 mm. In the door waterproof member 10 of the first embodiment, the thickness of the band-like waterproof portion 12 is set to 1 mm.

As shown in FIG. 1, the press-fitting convex portion 11 is formed on the inner surface of the band-like waterproof portion 12 (as shown in FIG. 11, when the door waterproof member 10 is attached to the gap D from the outside of the door 20). 20 (the same shall apply hereinafter)). The press-fitting protrusions 11 may be provided intermittently along the longitudinal direction of the water stop strip 12 , but are normally provided continuously along the longitudinal direction of the water stop strip 12 . In the door water-stopping member 10 of the first embodiment, the water-stopping strip 12 is continuously provided in the entire section from one end in the longitudinal direction of the water-stopping strip 12 to the other end in the longitudinal direction. As shown in FIG. 11, the press-fitting protrusion 11 is a portion that is held in the gap D by being press-fitted into the gap D from the outside of the door 20 . As a result, the door waterproof member 20 attached along the gap D can be prevented from moving from that position.

The press-fitting protrusion 11 is not particularly limited as long as it can exhibit the above functions. In the door waterproof member 10 of the first embodiment, as shown in FIG. 11, the press-fit projection 11 is composed of a main body projection 11a and a pair of branch projections 11b. The body convex portion 11a is a portion that protrudes in the depth direction of the gap D from the inner surface of the belt-like waterproof portion 12. As shown in FIG. The height _H1 of the main body convex portion 11a is not particularly limited, but is usually 5 to 30 mm, preferably 10 to 20 mm. In the door waterproof member 10 of the first embodiment, the height _H1 of the body protrusion 11a is set to 13 mm.

On the other hand, the branched convex portion 11b is a portion that protrudes in the width direction of the gap D (the direction of the width _W0 ) from both side surfaces of the main convex portion 11a. Each branched convex portion 11b is provided in the opposite direction with the main convex portion 11a interposed therebetween. Although the width W ₂ (FIG. 6) of the portion of the press-fitting protrusion 11 where the branch protrusion 11b is provided is set narrower than the width W ₁ (FIG. 11) of the strip-shaped waterproof portion 12, the width of the gap D It is set wider than W ₀ (FIG. 11). Therefore, when the press-fitting convex portion 11 is press-fitted into the gap D, the branch convex portion 11b is arranged so that the tip side of the branch convex portion 11b faces the front side of the press-fitting direction (outside the door 20) as shown in FIG. 11b is elastically deformed and inclined. As a result, the branch convex portion 11b is elastically stretched in the gap D, and the press-fitting convex portion 11 is held in the gap D. As shown in FIG.

Increasing the volume of the press-fitting projections 11 not only increases the amount of material (rubber, etc.) required for molding the door waterproof member 10, but also makes it difficult for the press-fitting projections 11 to elastically deform. It becomes difficult to press-fit the convex portion 11 into the gap D. In this respect, as described above, the volume of the press-fitting protrusion 11 can be reduced by forming the press-fitting protrusion 11 into a form having the main body protrusion 11a and the branched protrusion 11b. Therefore, not only is the amount of material used for molding the door waterproof member 10 reduced, but also the press-fitting projection 11b is made elastically deformable, making it easier to press-fit the press-fitting projection 11 into the gap D. be able to. For example, as shown in FIG. 9, when attaching the door waterproof member 10 along the gap D around the door 20, the first few centimeters along the longitudinal direction of the door waterproof member 10 If the press-fitting protrusion 11 is firmly press-fitted into the gap D only in the section, the press-fitting protrusion 11 in the remaining section can be press-fitted into the gap D simply by pressing the outer surface of the strip-shaped waterproofing section 12 with a finger. be able to

In addition, the branched convex portion 11b can also function as the second strip-shaped water stop portion 12. As shown in FIG. In other words, even if water enters the area α (FIG. 11) inside the strip-like water stop portion 12, the branched convex portion 11b can prevent the water from entering a deeper position of the gap D. . As shown in FIG. 11, when the press-fitting convex portion 11 is press-fitted into the gap D, the branching convex portion 11b is inclined such that the tip side of the branching convex portion 11b faces the front side of the press-fitting direction (the outside of the door 20). Therefore, when water enters the area α, the pressure of the water presses the branching convex portion 11b against the inner wall of the gap D (the end surface of the door 20 or the end surface of the door frame 40) (Fig. See arrow _A2 in 11). For this reason, the branched convex portion 11b is brought into a state in which it can exhibit higher watertightness.

In the door water stop member 10 of the first embodiment, as shown in FIG. The width is narrowed from the connected end (connected end) side to the distal end side. In addition, each branched convex portion 11b is also formed to have a triangular cross section, and the width increases from the base end (the end connected to the main body convex portion 11a) of each branched convex portion 11b toward the tip side. It is designed to be narrow. As a result, while maintaining the easiness of elastic deformation of the main body projection 11a and the branched projections 11b, the body projections 11a and the branched projections 11b are rigid enough to prevent the body projections 11a and the branched projections 11b from easily collapsing. It can be applied to the branched convex portion 11b.

The door waterproof member 10 of the first embodiment described above is installed along the gap D around the door 20 as shown in FIG. When the length of the door water stop member 10 is insufficient, the door water stop member 10 is added and constructed. Conversely, if the length of the door waterproof member 10 is excessive, the length is adjusted by cutting the excessive portion with a cutter, scissors, or the like. As shown in FIG. 8, the gaps D are present along the four sides of the door 20, and as shown in FIG. shown).

In many cases, the door waterproof member 10 is pushed in a direction perpendicular to the door 20 (see arrow _A3 in FIG. 9), but the edge of the door 20 (particularly, the pivot side of the swing door) An edge member 21 may be attached to the edge). When the door waterproof member 10 is attached to the gap D where the edge member 21 exists, the door waterproof member 10 is pushed in a direction parallel to the door 20 (see arrow _A4 in FIG. 9). .). The joints of the door waterproof member 10, such as the corners of the door 20, are separately attached with a waterproof adhesive tape or the like to stop water. Further, when the door 20 is a hinged door, a hinge 30 is provided at the edge on the pivot side thereof. The door waterproof member 10 cannot be attached to the portion where the hinge 30 exists. For this reason, the portion where the hinge 30 exists is also water-stopped by separately attaching a waterproof adhesive tape or the like.

When all of the above steps are completed, construction of the door waterproof member 10 is completed. In this state, all the gaps D existing around the door 20 are closed by the door waterproof member 10 or the like. Therefore, even if the outside of the door 20 is flooded, the water can be prevented from entering the inside of the door 20. - 特許庁

2. Door Water Stop Member of Second Embodiment Next, a door water stop member 10 of a second embodiment will be described. The door water stop member 10 of the second embodiment will be described with a focus on the structure different from that of the door water stop member 10 (FIGS. 1 to 11) of the first embodiment described above. For the configuration not particularly mentioned in the door water stop member 10 of the second embodiment, the same configuration as that of the door water stop member 10 of the first embodiment can be adopted. FIG. 12 is a view showing the door waterproof member 10 of the second embodiment. FIG. 12(a) shows a perspective view, and FIG. 12(b) shows a plan view.

In the door waterproof member 10 of the first embodiment described above, as shown in FIG. 1 , a pair of branched protrusions 11b facing in opposite directions extend from the same point on the body protrusion 11a from the base end side to the tip end side. It was provided so as to protrude in the lateral direction (the width direction of the gap D). In other words, the branch convex portion 11b has one step. On the other hand, in the door waterproof member 10 of the second embodiment, as shown in FIG. 12, the pair of branched projections 11b facing in opposite directions are arranged in different directions from the base end side to the tip end side of the main body projection 11a. It is provided in two stages in total. In this manner, the branched convex portion 12b can be provided in multiple stages. As a result, the press-fit projection 11 can be held in the gap D more firmly. In addition, even when water enters up to the area α (FIG. 11) inside the strip-like waterproof portion 12, it is possible to make it difficult for the water to break through the gap D.

In addition, in the door waterproof member 10 of the second embodiment, the protrusion amount of the branch protrusion 11b near the base end side of the main protrusion 11a (protrusion amount in the width direction of the gap D) is is set larger than the amount of protrusion of the branched convex portion 11b (the amount of protrusion in the width direction of the gap D) far from the base end side of the . In other words, the protruding amount of the branching protrusions 11 b farther from the strip-shaped water stop portion 12 is set smaller than the protrusion amount of the branching protrusions 11 b closer to the strip-shaped water stop portion 12 . This makes it easier to press-fit the door waterproof member 10 into the gap D around the door 20 even when the branched projections 11b are provided in multiple stages.

Further, in the door waterproof member 10 of the first embodiment described above, as shown in FIG. For this reason, the strip-shaped water stop part 12 is symmetrical when viewed from the main body convex part 11a. The amount of protrusion of the portion protruding to the other side from the main body convex portion 11a in . For this reason, for example, when the door waterproof member 10 is attached to the gap D (FIG. 8) on the lower side of the door 20, the belt-like waterproof member 12 protruding to one side from the main body convex portion 11a may not reach the floor. It was a structure that easily interfered with When the door water stop member 10 is attached to the gap D, if the band-shaped water stop portion 12 interferes with the surroundings, the band-shaped water stop portion 12 at that portion may float, allowing water to enter from that portion. be.

On the other hand, in the door waterproof member 10 of the second embodiment, as shown in FIG. It is set eccentrically. For this reason, the strip-shaped water stop part 12 is asymmetrical when viewed from the main body convex part 11a. is different from that of the portion protruding to the other side from the main body convex portion 11a. Therefore, even when the door water stop member 10 is attached to the gap D on the lower side of the door 20 as described above, the door water stop member 10 is arranged such that the side of the strip-shaped water stop portion 12 with a smaller amount of protrusion is the lower side (floor side). By attaching the water stop member 10, the band-shaped water stop part 12 can be prevented from interfering with the floor.

3. Door Water Stop Member of Third Embodiment Next, a door water stop member 10 of a third embodiment will be described. The door water-stopping member 10 of the third embodiment is similar to the door water-stopping member 10 of the first embodiment (FIGS. 1 to 11) and the door water-stopping member 10 of the second embodiment (FIG. 12). Description will be focused on different configurations. For configurations not particularly mentioned in the door water-stopping member 10 of the third embodiment, the same configurations as those of the door water-stopping member 10 of the first embodiment and the door water-stopping member 10 of the second embodiment may be adopted. can be done. 13A and 13B are diagrams showing a door waterproof member according to a third embodiment. FIG. FIG. 13(a) shows a perspective view, and FIG. 13(b) shows a plan view.

In the door waterproof member 10 of the first embodiment and the second embodiment described above, as shown in FIGS. had configured. On the other hand, in the door waterproof member 10 of the third embodiment, as shown in FIG. 13, the press-fit convex portion 11 is composed of a pair of inclined plate portions 11c. Each inclined plate portion 11c is provided so as to be inclined in the opposite direction from a predetermined position on the inner surface of the strip-like water stop portion 12. As shown in FIG. In this manner, the press-fitting projection 11 can be held in the gap D even when the press-fitting projection 11 is formed of the pair of inclined plate portions 11c. When press-fitting the press-fitting convex portion 11 into the gap D, the pair of inclined plate portions 11c are pinched and closed with fingers or the like. When the press-fitting convex portion 11 enters the gap D, the pair of inclined plate portions 11c are opened to be in a state of being stretched inside the gap D. As shown in FIG.

In the door waterproof member 10 of the third embodiment, the opening angle of the pair of inclined plate portions 11c is not particularly limited. However, when the opening angle of the pair of inclined plate portions 11c is small, it becomes difficult to keep the pair of inclined plate portions 11c in a state of being stretched within the gap D. Therefore, the opening angle of the pair of inclined plate portions 11c is preferably 30° or more. The opening angle of the pair of inclined plate portions 11c is more preferably 45° or more, more preferably 60° or more. However, if the opening angle of the pair of inclined plate portions 11c is too large, it becomes difficult to insert the pair of inclined plate portions 11c into the gap D. Therefore, the opening angle of the pair of inclined plate portions 11c is preferably 150° or less. The opening angle of the pair of inclined plate portions 11c is more preferably 120° or less, more preferably 90° or less. In the door waterproof member 10 of the third embodiment, the opening angle of the pair of inclined plate portions 11c is set to about 72°.

The door waterproof member 10 of the third embodiment can be suitably used when the width W ₀ (FIG. 11) of the gap D is wide. Therefore, in the door water-stopping member 10 of the third embodiment, the width of the strip-shaped water-stopping portion 12 (see width _W1 in FIG. 11) is the same as that of the door water-stopping member 10 of the first and second embodiments. It is set larger than the member 10 .

4. Door Water Stop Member of Fourth Embodiment Next, a door water stop member 10 of a fourth embodiment will be described. The door water stop member 10 of the fourth embodiment will be described by focusing on the configuration different from that of the door water stop member 10 (FIG. 13) of the above-described third embodiment. Regarding configurations not particularly mentioned in the door water-stopping member 10 of the fourth embodiment, the door water-stopping member 10 of the first embodiment, the door water-stopping member 10 of the second embodiment, and the door water-stopping member 10 of the third embodiment. A configuration similar to that of the door waterproof member 10 can be employed. 14A and 14B are diagrams showing a door waterproof member according to a fourth embodiment. FIG. FIG. 14(a) shows a perspective view, and FIG. 14(b) shows a plan view.

In the door water stop member 10 of the third embodiment described above, as shown in FIG. 13, a pair of inclined plate portions 11c constituting the press-fitting convex portion 11 protrude from the center of the belt-shaped water stop portion 12 in the width direction. was set in a state. On the other hand, in the door waterproof member 10 of the fourth embodiment, as shown in FIG. It is provided in a state of protruding from the displaced portion. The reason for doing so is that, in the door waterproof member 10 ( FIG. 12 ) of the second embodiment, the body protrusion 11 a of the press-fit protrusion 11 is shifted from the widthwise center of the band-shaped water stop portion 12 . It is the same as the reason why it is set eccentrically.

5. Uses As described above, the water stop member for a door of the present invention can be suitably used to close the gap around the door. The type of door to which the door waterproof member is attached is not particularly limited. The door waterproof member of the present invention can be used for both hinged doors and sliding doors. Further, the waterproof member for doors of the present invention may be used for doors of general houses, but is preferably used for doors of offices such as warehouses, factories, and stores. Among others, it is suitable for use in metal doors (iron doors, etc.).
