Description
本発明は、床材の改良、詳しくは、浴室等の床に使用した際の防滑性及び水捌けに優れると共に、転倒による怪我の危険や裸足で触れたときの不快な冷感も抑えることができ、しかも、足の皮膚の硬さに近い感触を有する床材に関するものである。 The present invention is an improvement in flooring, and more specifically, it is excellent in slip resistance and water drainage when used on floors such as bathrooms, and can also suppress the risk of injury due to falling and unpleasant cold feeling when touched with bare feet. And it is related with the flooring which has the touch close | similar to the hardness of the skin of a leg | foot.
周知のとおり、一般家庭の住宅の浴室や銭湯等の公衆浴場においては、陶磁器製のタイルを敷き詰めて床面の仕上げを行っていることが多い。しかし、このようなタイル貼りの床は、デザインバリエーションは豊富であるものの、施工時のタイル貼り作業に職人の高度な技巧が求められるため、施工コストが高い。 As is well known, in public bathrooms such as bathrooms and public baths of ordinary households, floors are often finished by laying ceramic tiles. However, although such a tiled floor has abundant design variations, it requires a high level of craftsmanship for the tiled work at the time of construction, so the construction cost is high.
また更に、上記陶磁器製のタイルは表面が硬いため、入浴者が転倒した際に頭や肘、膝等を強く打って怪我をする危険も大きい。加えて、陶磁器製のタイルは熱伝導率も高いため、入浴者がタイル貼りの床上に座ったり、横になったりした際に、冷たいタイルに体温が奪われて不快な冷たさを感じ易い。 Furthermore, since the ceramic tiles have a hard surface, there is a great risk of injury by hitting the head, elbows, knees, etc. when the bather falls. In addition, ceramic tiles have high thermal conductivity, so when a bather sits on a tiled floor or lies down, the cold tiles easily lose their body temperature and feel uncomfortable coldness.
そこで、従来においては、上記浴室の床面に使用する床材として、表面にタイル状の凸部が形成されたプラスチック製の床材も開発されている(特許文献１,２参照)。また、これらの床材に関しては、凸部間にタイル目地状に形成された溝部を利用して、床上に掛けられた水の排出を効率的に行えるようにしている。 Therefore, conventionally, plastic floor materials having tile-shaped convex portions formed on the surface have been developed as floor materials used for the floor surface of the bathroom (see Patent Documents 1 and 2). In addition, regarding these floor materials, the grooves formed in the shape of tile joints between the convex portions are used to efficiently discharge water hung on the floor.
しかしながら、上記文献１に記載された床材においては、凸部上に付着した水滴が周囲の溝部に流れ落ちずにそのまま凸部上に残留し易いという欠点があるため、床材表面に形成する凸部の面積を大きくすればする程、凸部上に残留する水滴の量が多くなって床材の水捌けが悪くなるという問題が生じる。 However, the flooring described in the above-mentioned document 1 has a defect that water droplets adhering to the convex part do not flow down to the surrounding groove part and remain on the convex part as they are. As the area of the portion is increased, the amount of water droplets remaining on the convex portion is increased, resulting in a problem that the floor material is poorly drained.
一方、上記文献２に記載された床材に関しては、凸部上に付着した水滴が溝部に流れ落ちるように凸部を湾曲形状としているが、凸部のサイズを同じ曲率で大きくすると、凸部の厚みが大きくなり過ぎて足や体が触れたときの感触が不快になり易い。また、凸部の曲率を下げると水滴が溝部に流れ落ちる機能が弱まって水捌けが悪化し易い。 On the other hand, regarding the flooring described in the above-mentioned document 2, the convex portion is curved so that water droplets adhering to the convex portion flow down to the groove portion. However, if the size of the convex portion is increased with the same curvature, the convex portion When the thickness becomes too large and the foot or body touches, the touch tends to be uncomfortable. Moreover, if the curvature of a convex part is lowered | hung, the function that a water drop will flow into a groove part will weaken, and a water drop will deteriorate easily.
また他にも、表面に複数のリブ状突起を並べて形成した床材も従来において公知となっているが(特許文献３参照)、この文献３に記載された床材は、横向きのリブ状突起を帯状に並べただけの形状であるため、床材表面にタイル状の模様を形成できない上に、床材を使用する向きも一方向に限定されてしまう。 In addition, a flooring in which a plurality of rib-like protrusions are arranged on the surface is also known in the past (see Patent Document 3). However, the flooring described in this document 3 is a lateral rib-like protrusion. Therefore, the tile-like pattern cannot be formed on the floor material surface, and the direction in which the floor material is used is limited to one direction.
本発明は、従来技術に上記問題があったことに鑑みて為されたものであり、その目的とするところは、浴室等の床に使用した際の防滑性および水捌けに優れると共に、転倒による怪我の危険や触れたときの不快な冷感や感触も抑えることができ、更に人の足の裏の硬さに近く歩き易い上に、表面にタイル状の模様も形成でき、しかも、使用する向きも一方向に限定されない床材を提供することにある。 The present invention has been made in view of the above-mentioned problems in the prior art, and its object is to provide excellent slip resistance and water drainage when used on a floor such as a bathroom, as well as injury due to falling. It is also possible to suppress the unpleasant cold feeling and touch when touched, and it is easy to walk close to the hardness of the sole of a person's foot, and a tiled pattern can be formed on the surface, and the orientation to use Another object is to provide a flooring that is not limited to one direction.
本発明者が上記技術的課題を解決するために採用した手段を、添付図面を参照して説明すれば、次のとおりである。 Means employed by the present inventor for solving the above technical problem will be described with reference to the accompanying drawings.
即ち、本発明は、合成樹脂材料又はエラストマー材料から成る表面層１を有し、かつ、表面層１上に凹凸が形成された床材において、
前記表面層１の凹凸を、格子状に形成された主排水溝11・11…と、この主排水溝11・11…によって仕切られた複数の突起集合部12・12…とから構成すると共に、
前記突起集合部12・12…を、四隅に間隙Ｓ・Ｓ…を有する外枠突起12aと、この外枠突起12a内に形成された中央突起群12bとから構成して、これら外枠突起12aと中央突起群12bの間、及び中央突起群12bの各突起間にそれぞれ副排水溝12cを設けたことにより、
斜めに傾けて(水勾配を設けた状態で)設置した上記床材Ｆ表面が濡れたとき、前記突起集合部12・12…内に付着した水滴Ｗ・Ｗ…が、副排水溝12cを通って主排水溝11・11…に排出されるようにした点に特徴がある。
That is, the present invention has a surface layer 1 made of a synthetic resin material or an elastomer material, and a floor material in which irregularities are formed on the surface layer 1,
The unevenness of the surface layer 1 is composed of main drainage grooves 11, 11 formed in a lattice shape, and a plurality of projection collecting parts 12, 12 partitioned by the main drainage grooves 11, 11.
The projection assembly portions 12, 12... Are constituted by outer frame projections 12a having gaps S, S... At four corners, and a central projection group 12b formed in the outer frame projections 12a, and these outer frame projections 12a. By providing the sub drainage grooves 12c between the projections of the central projection group 12b and between the projections of the central projection group 12b,
When the surface of the floor material F installed obliquely (with a water gradient provided) gets wet, water droplets W · W adhering in the projection collecting portions 12 · 12 ··· pass through the auxiliary drainage grooves 12c. It is characterized in that it is discharged into the main drainage grooves 11.
また、上記表面層１に形成する突起集合部12の中央突起群12bについては、外枠突起12aと同様にリブ状突起を四方に配置した複数の内枠突起Ｎ・Ｎ…を含んで構成すると共に、これらの内枠突起Ｎ・Ｎ…を外枠突起12a内に入れ子状に形成して、外枠突起12a内に対角線方向の間隙Ｓ・Ｓを繋ぐ副排水溝12cを形成することができる。そしてこれにより、突起集合部12における水の侵入・排出ルートを対角線方向の副排水溝12cによって確保することができるため、突起集合部12内の水の排水効果を高めることができる。 Further, the central projection group 12b of the projection assembly portion 12 formed on the surface layer 1 includes a plurality of inner frame projections N, N,... With rib-like projections arranged in four directions, like the outer frame projection 12a. At the same time, these inner frame protrusions N, N,... Can be nested in the outer frame protrusion 12a to form a sub drainage groove 12c that connects the diagonal gaps S, S in the outer frame protrusion 12a. . As a result, the water intrusion / discharge route in the protrusion collecting portion 12 can be secured by the sub drain grooves 12c in the diagonal direction, so that the water draining effect in the protrusion collecting portion 12 can be enhanced.
また更に、本発明では、上記表面層１に形成した突起集合部12において、少なくとも外枠突起12および内枠突起Ｎ・Ｎ…の何れか一方を構成するリブ状突起を、両端から中央にかけて突起幅が大きくなる中太り形状とすることができる。そしてこれにより、リブ状突起が、水滴の流れ落ちる方向に対して垂直に形成されている場合でも、リブ状突起に傾斜が付いているため、水滴がリブ状突起に中央から両端側に流れ易くなる。また、リブ状突起が、水滴の流れ落ちる方向に対して平行に形成されている場合でも、リブ状突起間に形成される副排水溝12cに局部的に幅が狭くなったしぼり部を設けることができるため、オリフィス効果によって水滴の流れ落ちを促進することが可能となる。 Furthermore, in the present invention, in the projection assembly portion 12 formed on the surface layer 1, rib-like projections constituting at least one of the outer frame projections 12 and the inner frame projections N · N are projected from both ends to the center. It can be made into a middle-thick shape with an increased width. As a result, even when the rib-shaped protrusions are formed perpendicular to the direction in which the water droplets flow down, the rib-shaped protrusions are inclined, so that the water droplets easily flow from the center to the both end sides. . Further, even when the rib-like projections are formed in parallel to the direction in which the water droplets flow down, it is possible to provide a constricted portion having a locally narrow width in the auxiliary drainage groove 12c formed between the rib-like projections. Therefore, it is possible to promote the flow-down of water droplets by the orifice effect.
また、本発明においては、各突起集合部12・12…から主排水溝11・11…に大量の水滴が排出された際でも、主排水溝11に沿って水が流れ落ちるように、表面層１の主排水溝11・11…の溝幅を、突起集合部12内の副排水溝12cの溝幅よりも大きく形成することができる。 In the present invention, even when a large amount of water droplets are discharged from the projection collecting portions 12, 12, into the main drain grooves 11, 11, the surface layer 1 so that the water flows down along the main drain grooves 11. The main drain grooves 11, 11... Can be formed larger than the groove width of the sub drain grooves 12c in the projection collecting portion 12.
そしてまた、本発明では、上記副排水溝12cによる排水効果を高めるために、表面層１の各突起集合部12・12…において、外枠突起12aと中央突起群12bを含む突起面積の割合を全体の面積に対して３０〜７０％、好ましくは５０％以下とするのが好ましい。また、上記表面層１に形成した主排水溝11・11…及び副排水溝12cの溝幅についても、水滴の表面張力を壊して水滴の拡張濡れを促進できるように0.1〜5.0mmの範囲で設計するのが好ましい。また、上記表面層１に形成された主排水溝11・11…及び副排水溝12cの溝の深さについても、水滴の拡張濡れを促進できるように0.1〜1.0mmの範囲で設計するのが好ましい。 Further, in the present invention, in order to enhance the drainage effect by the sub drainage groove 12c, the ratio of the projection area including the outer frame projection 12a and the central projection group 12b in each projection assembly portion 12, 12. The total area is 30 to 70%, preferably 50% or less. In addition, the groove widths of the main drain grooves 11, 11... And the sub drain grooves 12c formed in the surface layer 1 are also in the range of 0.1 to 5.0 mm so that the surface tension of the water droplets can be broken to promote the expanded wetting of the water droplets. It is preferable to design. Further, the depths of the main drain grooves 11, 11... And the sub drain grooves 12c formed in the surface layer 1 are designed in the range of 0.1 to 1.0 mm so as to promote the expansion wetness of water droplets. preferable.
他方また、本発明においては、表面層１のクッション効果及び滑り止め効果を高めるために、表面層１の材料に、軟質塩化ビニル樹脂、オレフィン系エラストマー、スチレン系エラストマー、ポリエステル系エラストマー、或いはポリアミド系エラストマー材料を採用することができる。そして更に、床材のクッション効果を高めるために、上記表面層１の裏側に発泡樹脂材料から成るクッション層２を形成することもできる。 On the other hand, in the present invention, in order to enhance the cushioning effect and anti-slip effect of the surface layer 1, the material of the surface layer 1 includes soft vinyl chloride resin, olefin elastomer, styrene elastomer, polyester elastomer, or polyamide resin. Elastomeric materials can be employed. Further, in order to enhance the cushioning effect of the flooring material, a cushion layer 2 made of a foamed resin material can be formed on the back side of the surface layer 1.
本発明では、水勾配床に用いられる床材の表面の凹凸部を、タイル目地状に形成した主排水溝と、この主排水溝によって区切られた複数の突起集合部とから構成すると共に、突起集合部を、四隅に間隙を有する外枠突起と、その内側の突起群とから構成したことにより、突起集合部に付着した水滴を、突起集合部内の副排水溝によって拡張させて、周囲の水滴と集合一体化させることで大きな水滴に成長させ易くなる。 In the present invention, the uneven portion on the surface of the flooring material used for the water gradient floor is composed of a main drainage groove formed in a tile joint shape, and a plurality of projection aggregate portions separated by the main drainage groove, and a projection Since the collecting portion is composed of the outer frame projections having gaps at the four corners and the inner projection group, the water droplets adhering to the projection collecting portion are expanded by the sub drainage grooves in the projection collecting portion, and the surrounding water droplets are expanded. It becomes easy to grow into large water droplets by gathering together.
そして更に、上記突起集合部内で成長させた水滴は、外枠突起の下側の間隙から主排水溝に排出することができるため、突起集合部の面積を大きく設計する場合でも、床材の良好な水捌けを維持することができる。また、突起集合部内に付着した水滴の量が少ない場合でも、外枠突起の上側の間隙から突起集合部内に侵入した主排水溝の水によって、突起集合部内の水滴を集合一体化させることができる。 Furthermore, since the water droplets grown in the projection assembly part can be discharged to the main drainage groove from the lower gap of the outer frame projection, the flooring material is good even when the area of the projection assembly part is designed to be large. Can maintain a good water drain. Further, even when the amount of water droplets adhering to the protrusion collecting portion is small, the water droplets in the protrusion collecting portion can be integrated and integrated by the water in the main drainage groove that has entered the protrusion collecting portion from the gap above the outer frame protrusion. .
また更に、本発明の床材では、表面に突起集合部を設けることによって滑り止め効果を得られるだけでなく、床材表面にタイル状の模様を形成することもできる。加えて、本発明においては、床材の表面層を比較的柔軟で熱伝導性の低い合成樹脂材料またはエラストマー材料から作製しているため、ユニットバスの床板に貼り付けた際に人の足の裏に似た硬さになり、転倒時の怪我の危険や触れたときの不快な冷感も軽減することができる。 Furthermore, in the floor material of the present invention, not only an anti-slip effect can be obtained by providing a protrusion assembly portion on the surface, but also a tile-like pattern can be formed on the floor material surface. In addition, in the present invention, the surface layer of the flooring material is made of a synthetic resin material or an elastomer material that is relatively flexible and has low thermal conductivity. It has a hardness similar to that of the back, reducing the risk of injury when falling and the unpleasant feeling of cold when touched.
しかも、本発明では、上記突起集合部の面積を大きく設計する場合でも、突起の厚みを大きくする必要がないため、突起集合部によって床面の感触が不快になることもない。そしてまた、本発明の床材では、突起集合部の外枠突起の四隅に間隙を設けているため、床材の使用方向が不要に限定されることもない。 Moreover, in the present invention, even when the area of the protrusion assembly portion is designed to be large, it is not necessary to increase the thickness of the protrusion. Moreover, in the floor material of the present invention, since the gaps are provided at the four corners of the outer frame protrusions of the protrusion assembly portion, the use direction of the floor material is not unnecessarily limited.
したがって、本発明により、浴室等の床材に使用した際の歩き易さ及び安全性に優れる上に、床面のデザイン自由度も高く、しかも、従来の床材と比較して水捌け性能の改善も図れる水勾配床用の床材を提供できることから、本発明の実用的価値は頗る高い。 Therefore, according to the present invention, it is excellent in ease of walking and safety when used in flooring materials such as bathrooms, and also has a high degree of freedom in designing the floor surface, and further improved in water draining performance compared to conventional flooring materials. Therefore, the practical value of the present invention is very high.
