以下、本発明の好適な実施の形態について詳細に説明する。
図１は、本発明に係る防水部材の一実施形態の構成を示す斜視図である。
図１に示すように、本実施形態の防水部材１０は、直交する２本の区画線Ａ，Ｂにより四つに区画され、そのうちの一区画がＬ字状に切り欠かれた切欠き部１２を有する第一のシート部１４と、Ｌ字をなす２直線１６，１８から、それぞれ第一のシート部１４に対して直交して延出し、且つ互いに直角に屈曲して設けられた第二のシート部２０及び第三のシート部２２とが一体に形成されているものである。 Hereinafter, preferred embodiments of the present invention will be described in detail.
FIG. 1 is a perspective view showing a configuration of an embodiment of a waterproof member according to the present invention.
As shown in FIG. 1, the waterproof member 10 of the present embodiment is divided into four parts by two perpendicular dividing lines A and B, one of which is cut out in an L shape. The first sheet part 14 having the L and the two straight lines 16 and 18 having an L-shape extend perpendicular to the first sheet part 14 and bend at right angles to each other. The sheet part 20 and the third sheet part 22 are integrally formed.

具体的には、第一のシート部１４は、正方形状のシートを、対向する端辺２４の略中点同士を結んだ２本の区画線Ａ，Ｂにより四分割し、そのうちの一区画を、直線１６，１８に沿ってＬ字に切り欠くことでＬ字状の切欠き部１２が形成されているものである。
また、第二のシート部２０及び第三のシート部２２は、第一のシート部１４の切欠き部１２をなす一方または他方の直線１６，１８を短辺とし、長辺が第一のシート部１４の端辺２４と同じ長さに形成された長方形状に設けられているものである。 Specifically, the first sheet portion 14 divides a square sheet into four by two dividing lines A and B connecting the substantially midpoints of the opposite end sides 24, and one section thereof is divided. The L-shaped cutout portion 12 is formed by cutting out into an L shape along the straight lines 16 and 18.
In addition, the second sheet portion 20 and the third sheet portion 22 have one or the other straight lines 16 and 18 forming the cutout portion 12 of the first sheet portion 14 as the short side, and the long side is the first sheet. It is provided in a rectangular shape having the same length as the end side 24 of the portion 14.

上記３つのシート部１４，２０，２２が一体に形成された防水部材１０は、軟質合成樹脂シートとして厚さが約０．３mmの軟質塩化ビニルシートからなり、防水部材１０をどの位置においても折り曲げることができるように形成されている。
これにより、三平面がそれぞれ略直交して形成されるあらゆる形状のコーナ部に用いることができ、コーナ部を防水することが可能となる。以下、使用例を図２〜図４により具体的に説明する。 The waterproof member 10 in which the three sheet portions 14, 20, and 22 are integrally formed is a soft vinyl chloride sheet having a thickness of about 0.3 mm as a soft synthetic resin sheet, and the waterproof member 10 is bent at any position. It is formed so that it can be.
Thereby, it can use for the corner part of all the shapes in which three planes are formed substantially orthogonally, respectively, and it becomes possible to waterproof a corner part. Hereinafter, usage examples will be described in detail with reference to FIGS.

図２は、二つの角材２５，２５が直交して接合された部材の入隅部２６と、入隅部２６をなす角材の内側面２８，２８と直交する角材の前面２９とからなる入隅コーナ部３０に防水部材１０を用いた場合の使用例を示す斜視図である。
この場合には、前面２９に第一のシート部１４をあて、入隅部２６に第二及び第三のシート部２０，２２を合わせて、接着剤やテープ等で貼り付けたり、釘等の留め具で留めたりして固定することで入隅コーナ部３０を覆い防水することが可能となる。 FIG. 2 shows an entrance corner composed of an entrance corner portion 26 of a member in which two square members 25, 25 are joined at right angles, and an inside surface 28, 28 of the square member forming the entrance corner portion 26, and a front face 29 of the square material perpendicular to the corner. 4 is a perspective view showing an example of use when a waterproof member 10 is used for a corner portion 30.
In this case, the first sheet portion 14 is applied to the front surface 29 and the second and third sheet portions 20 and 22 are aligned to the corner 26 and are adhered with an adhesive, tape, or the like. The corner portion 30 can be covered and waterproofed by fastening with a fastener and fixing.

図３は、二つの角材２５，２５を直交させて形成される出隅部３４と角材の前面２９により形成される出隅コーナ部３８に防水部材１０を用いた場合の使用例を示す斜視図である。
この場合には、先ず、図３(a)に示すように、出隅部３４をなす角材２５の外側面２７，２７に第二及び第三のシート部２０，２２を合わせる。次に、区画線Ａで第一のシート部１４を折り曲げ（図３(b)）、さらに、第一のシート部１４の重なった部分を区画線Ｂで曲げて（図３(c)）固定することで、簡単に出隅コーナ部３８を覆うことができる。 FIG. 3 is a perspective view showing an example of use in the case where the waterproof member 10 is used in a corner portion 38 formed by a protruding corner portion 34 formed by orthogonally intersecting two square members 25 and 25 and a front surface 29 of the square member. It is.
In this case, first, as shown in FIG. 3A, the second and third sheet portions 20 and 22 are aligned with the outer side surfaces 27 and 27 of the square member 25 forming the protruding corner portion 34. Next, the first sheet portion 14 is bent along the lane marking A (FIG. 3B), and the overlapping portion of the first sheet portion 14 is bent along the lane marking B (FIG. 3C) and fixed. By doing so, the corner portion 38 can be easily covered.

このように、本実施形態の防水部材１０においては、区画線Ａ、区画溝Ｂで折曲自在に設けられていることから、三平面がそれぞれ直交して形成されるコーナ部の形状に合わせて防水部材を被覆することができる。このため、入隅コーナ部用と出隅コーナ部用の防水部材を別々に製造する必要がないことから、少品種多量の製造ができ、防水部材を廉価にすることが可能となる。   Thus, in the waterproof member 10 of this embodiment, since it is provided so that it can be bent by the dividing line A and the dividing groove B, it matches with the shape of the corner part in which three planes are formed orthogonally, respectively. The waterproof member can be coated. For this reason, it is not necessary to separately manufacture the waterproof members for the in-corner corner portion and the outer-corner corner portion, so that it is possible to manufacture a small number of products in large quantities and to make the waterproof member inexpensive.

また、本実施形態の防水部材１０は、図１に示すように、第一のシート部１４の被覆幅（Ｌ字の切欠き部１２をなす直線１６，１８から、この直線１６，１８と対向する第一のシート部１４の端辺２４までの長さ）よりも、第二及び第三のシート部２０，２２の被覆幅（Ｌ字の切欠き部１２をなす直線１６，１８から、この直線１６，１８と対向する第二及び第三のシート部２０，２２の端辺２０ａ，２２ａまでの長さ）の方が長く形成されている。
このため、重点的に防水したい部位に、被覆面積の大きい第二及び第三のシート部２０，２２を合わせることで、防水部材１０を効果的に使用することが可能である。使用例を図４に示す。 Further, as shown in FIG. 1, the waterproof member 10 of the present embodiment is opposed to the straight line 16, 18 from the covering width of the first sheet portion 14 (the straight line 16, 18 forming the L-shaped notch 12). From the straight widths 16 and 18 forming the L-shaped cutout portions 12 to the covering widths of the second and third sheet portions 20 and 22 rather than the length to the end side 24 of the first sheet portion 14 The lengths of the second and third sheet portions 20 and 22 facing the straight lines 16 and 18 (the lengths up to the end sides 20a and 22a) are longer.
For this reason, it is possible to use the waterproof member 10 effectively by combining the second and third sheet portions 20 and 22 having a large covering area with a portion to be waterproofed with priority. An example of use is shown in FIG.

図４は、壁体３１に設けられた開口部３３に窓枠をはめ込む際の、開口部３３角部の入隅部４２と、壁体３１の壁面３６とにより形成される入隅コーナ部４０に、防水部材１０を用いた場合の使用例である。
この場合には、角部４４を重点的に防水したい。このため、図４(a)に示すように、第二及び第三のシート部２０，２２を角部４４に合わせ、図４(b)に示すように、第一のシート部１４の区画線Ａにおいて折り曲げ、壁面３６に沿わせて固定している。
このように、本実施形態の防水部材１０は、第一のシート部１４の被覆面積と、第二及び第三のシート部２０，２２の被覆面積とが異なるように形成され、且つ区画線Ａ，Ｂにおいて屈曲自在に設けられていることから、防水効果を高めるような配置で防水部材を設けることが可能である。 FIG. 4 shows a corner portion 40 formed by the corner portion 42 of the corner portion of the opening portion 33 and the wall surface 36 of the wall portion 31 when the window frame is fitted into the opening portion 33 provided in the wall body 31. Further, it is an example of use when the waterproof member 10 is used.
In this case, the corner 44 is desired to be waterproofed. Therefore, as shown in FIG. 4A, the second and third sheet portions 20 and 22 are aligned with the corner portion 44, and as shown in FIG. 4B, the dividing line of the first sheet portion 14 is obtained. It is bent at A and fixed along the wall surface 36.
Thus, the waterproof member 10 of the present embodiment is formed such that the covered area of the first sheet portion 14 is different from the covered areas of the second and third sheet portions 20 and 22, and the dividing line A , B are provided so as to be freely bent, it is possible to provide the waterproof member in an arrangement that enhances the waterproof effect.

なお、本発明に係る防水部材１０は、上記記載の実施の形態に限定されるものでない。
例えば、本実施形態においては、軟質合成樹脂シートとして塩化ビニルシートを用いているが、これに限定されるものではなく、ポリエチレンシートや軟性ゴムシートなどであっても良い。ただし、厚さが約３．０ｍｍ以上になると折り曲げにくくなることから、シートの厚さは約５０μｍ〜３．０ｍｍであることが好ましい。 The waterproof member 10 according to the present invention is not limited to the embodiment described above.
For example, in this embodiment, a vinyl chloride sheet is used as the soft synthetic resin sheet, but the present invention is not limited to this, and a polyethylene sheet or a soft rubber sheet may be used. However, since it becomes difficult to bend when the thickness is about 3.0 mm or more, the thickness of the sheet is preferably about 50 μm to 3.0 mm.

また、防水部材１０を折り曲げやすくするために、第一のシート部１４の区画線Ａ，Ｂ上に折曲ガイド溝を設けることでも良い。折曲ガイド溝としては、例えば、図５(a)に示すように、第一のシート部１４の一面側の区画線Ａ，Ｂ上に、凹状の折曲ガイド溝５２を形成することでも良いし、図５(ｂ)に示すように、シート部の両面側から凹状の折曲ガイド溝５４，５４を設けることであっても良い。あるいは、図５(c)に示すように、区画線上の屈曲した角部に、凹状の折曲ガイド溝５６を設けることであっても良い。   Moreover, in order to make the waterproof member 10 easy to bend, a bending guide groove may be provided on the partition lines A and B of the first sheet portion 14. As the bending guide groove, for example, as shown in FIG. 5A, a concave bending guide groove 52 may be formed on the partition lines A and B on the one surface side of the first sheet portion 14. However, as shown in FIG. 5B, concave bent guide grooves 54, 54 may be provided from both sides of the sheet portion. Alternatively, as shown in FIG. 5 (c), a concave bent guide groove 56 may be provided at a bent corner on the partition line.

このように、第一のシート部１４に折曲ガイド溝を形成すると、折り曲げ位置が規制されることから、防水部材の取り付け技術がない人でも、簡単且つ確実に防水部材の取り付けを行うことができる。
また、折曲ガイド溝を設けた場合には、厚いシートを用いても折曲ガイド溝により簡単に曲げることができることから、折曲ガイド溝を設けていない場合に比べシートを厚く形成することが可能である。これにより防水効果を高めることが可能となる。 As described above, when the bending guide groove is formed in the first sheet portion 14, the bending position is restricted. Therefore, even a person who does not have a waterproof member mounting technique can easily and reliably attach the waterproof member. it can.
In addition, when the bending guide groove is provided, the sheet can be easily bent by the bending guide groove even when a thick sheet is used. Therefore, the sheet can be formed thicker than when the bending guide groove is not provided. Is possible. As a result, the waterproof effect can be enhanced.

さらに、本発明に係る防水部材１０に軟性合成樹脂材を用いた場合は、単に区画線Ａ，Ｂだけで折曲自在に設けられているだけでなく、例えば、図６に示すように、区画線Ａと区画線Ｂが直交してできる角Ｃ，Ｄ，Ｅを二分割するように交点Ｆから端辺２４まで延出する折曲線Ｇ，Ｈ，Ｉなどにおいても折り曲げることができる。これにより、多様な形状のコーナ部にフィットさせることができるし、また、直角でないコーナ部に使用することも可能である。   Furthermore, when a soft synthetic resin material is used for the waterproof member 10 according to the present invention, the waterproof member 10 is not only provided so as to be foldable only by the dividing lines A and B, but also, for example, as shown in FIG. It is also possible to fold along folding lines G, H, I, etc. extending from the intersection point F to the edge 24 so as to divide the angles C, D, E formed by the line A and the dividing line B perpendicularly. Thereby, it can be made to fit the corner part of various shapes, and it is also possible to use it for the corner part which is not a right angle.

また、本発明にかかる防水部材１０は、防水部材１０全体が軟質合成樹脂材で形成されていることに限定されるものではなく、少なくとも２本の区画線Ａ，Ｂ上において折曲自在に形成されていれば良いものである。すなわち、折り曲げる部分のみを柔らかくしたものであっても良い。
このため、図７に示すように、２本の区画線Ａ，Ｂ上の帯状部分４８のみが軟質合成樹脂材で形成されて折曲自在に設けられ、その他の部分５０が硬質合成樹脂材で形成されていることであっても良い。 Further, the waterproof member 10 according to the present invention is not limited to the entire waterproof member 10 being formed of a soft synthetic resin material, and is formed to be foldable on at least two partition lines A and B. It is good if it is done. That is, only the part to be bent may be softened.
Therefore, as shown in FIG. 7, only the band-like portions 48 on the two lane markings A and B are formed of a soft synthetic resin material and are foldable, and the other portions 50 are made of a hard synthetic resin material. It may be formed.

さらに、本実施形態では、第一のシート部１４として正方形状のシートを切り欠いたものについて説明したが、本発明においてはこれに限定されるものではなく、長方形や多角形、円形などどのような形状のものであっても良い。また、第一のシート部１４を区画する２本の区画線Ａ，Ｂも直交していればどのように配置されていても良い。   Further, in the present embodiment, the first sheet portion 14 has been described with a square sheet cut out. However, the present invention is not limited to this, and is not limited to this, but may be a rectangle, polygon, or circle. It may be of any shape. Further, the two lane markings A and B that divide the first sheet portion 14 may be arranged in any manner as long as they are orthogonal to each other.

本発明に係る防水部材１０は、特に使用用途を限定するものではない。例えば、レンジのフードの内側面や、ベランダ等の手すりの笠木、屋根と屋根の継ぎ目等に用いることが可能である。   The waterproof member 10 according to the present invention does not particularly limit the intended use. For example, it can be used for the inner surface of a range hood, a handrail of a handrail such as a veranda, and a roof-to-roof seam.
