Description

【０００１】
【発明の属する技術分野】
本発明は、床見切りに関するものであり、詳しくは、フローリングの小口やカーペットの縁などの床表面材の端部を覆うための床見切りに関するものである。
【０００２】
【従来の技術】
周知の通り、床見切りは、フローリングの小口、じゅうたんやカーペットの縁などの床表面材の端部を覆い、他の床材などとの縁を切るための長尺物の建築部材である。図４は、従来の床見切りの形状を示す図であり、長手方向に直交する断面図である。
【０００３】
図４に示す様に、従来の床見切りは、例えば、上面に１組の立上り片（５１）が突設され且つ床下地（９）に固定される受け材（５）と、下面に１組の溝（６１）が設けられ且つこれらの溝（６１）に立上り片（５１）を相対的に挿入することにより受け材（５）に組み付けられる見切り材（６）とから構成され、見切り材（６）の組付けにより鍔（６４）によって床表面材（８）の端部を押え付ける様になされている。そして、外れ防止の観点から、受け材（５）の各立上り片（５１）の上端部には膨出部（５３）が設けられ、見切り材（６）の各溝（６１）の奥端部には膨出部（５３）が嵌合する凹部（６３）が設けられる。
【０００４】
【発明が解決しようとする課題】
ところで、従来の床見切りは、受け材に見切り材を組み付けようとした場合、見切り材の溝に対して受け材の立上り片が予めきつく嵌合する様に形成されているため、ハンマーによって見切り材に衝撃を与える等して立上り片と溝とを強制的に嵌合させなければならず、施工性に欠けると言う問題がある。更に、上記の様に見切り材が取付け難い反面、施工後は、受け材の立上り片および見切り材の溝が塑性変形しているため、受け材から見切り材が比較的外れ易く、また、室内の内装変更の際などに一旦受け材から見切り材を取り外した場合には、受け材の立上り片と見切り材の溝との強い嵌合が得られないため、再使用できないと言う問題がある。
【０００５】
本発明は、上記の実情に鑑みなされたものであり、その目的は、立上り片が突設された受け材と、前記の各立上り片を相対的に挿入する溝が設けられた見切り材とから成る嵌合方式の床見切りであって、施工性に優れ、施工後は受け材から見切り材が外れ難く、しかも、繰り返して使用することが出来る改良された床見切りを提供することにある。
【０００６】
【課題を解決するための手段】
上記の課題を解決するため、本発明の床見切りは、上面に１組の立上り片がレール状に突設され且つ床に固定される長尺物の受け材と、下面に１組の溝が設けられ且つこれらの溝に前記各立上り片を相対的に挿入することにより前記受け材に組み付けられる長尺物の見切り材とから成る床見切りであって、前記見切り材の各溝の開口部の外側の角部には面取りが施され、かつ、前記見切り材の各溝の最小幅が前記受け材の各立上り片の最大厚さよりも大きく設定され、しかも、前記受け材の各立上り片は互いに基端側から先端側に向かうに従い漸次離間する傾斜状態に設けられ、かつ、これら立上り片の各外側の壁面には段差をつけて膨出部が設けられ、前記見切り材の各溝は互いに開口側から奥端側に向かうに従い漸次離間する傾斜状態に設けられ、かつ、これら溝の各外側の内壁面には前記膨出部が嵌合する凹部が備えられていることを特徴とする。
【０００７】
すなわち、上記の床見切りにおいては、見切り材の溝に受け材の立上り片を相対的に挿入して組み付けるにあたり、見切り材の溝の開口部の外側の角部における面取り構造は、挿入される受け材の立上り片を見切り材の溝の内部へ案内する様に機能し、また、見切り材の溝の最小幅を受け材の立上り片の最大厚さよりも大きく設定した構造は、見切り材の溝に対する受け材の立上り片の円滑な挿入を可能にする。そして、受け材の立上り片および見切り材の溝の傾斜構造、ならびに、立上り片の外側の壁面の膨出部と溝の外側の内壁面の凹部との嵌合構造は、受け材に見切り材を組み付けた場合、立上り片の溝からの垂直方向の抜けを規制し、受け材と見切り材との高い結合力を維持する。
【０００８】
【発明の実施の形態】
本発明に係る床見切りの一実施形態を図面に基づいて説明する。図１は、本発明に係る床見切りの受け材および見切り材の形状を示す図であり、長手方向に直交する断面図である。図２は、本発明に係る床見切りの受け材と見切り材の組付け操作における部位の挙動を示す上記と同様の断面図であり、図３は、本発明に係る床見切りの組付後の状態を示す上記と同様の断面図である。
【０００９】
本発明の床見切りは、フローリングの小口、じゅうたんやカーペットの縁などの床表面材の端部を覆う建築部材であり、図１に示す様に、床表面材（８）の端部に沿って床下地（９）等の床に敷設される。図に例示した床見切りは、１枚の床表面材（８）の端部を処理するためのいわゆる掃出し用の見切りである。
【００１０】
本発明の床見切りは、図１に示す様に、上面に１組の立上り片（３）がレール状に突設され且つ床に固定される長尺物の受け材（１）と、下面に１組の溝（４）が設けられ且つこれらの溝（４）に立上り片（３）を相対的に挿入することにより受け材（１）に組み付けられる長尺物の見切り材（２）とから構成される。受け材（１）及び見切り材（２）は、処理すべき床表面材（８）の小口の長さに応じて、１本を必要な長さに切断したり、複数本を連続的に並べて使用される。
【００１１】
受け材（１）は、これに見切り材（２）を組み付ける際に後述する立上り片（３）を弾性変形させるため、通常はポリアミド６、ポリアミド６−６、ポリアミドイミド等のポリアミド系樹脂、ポリエチレン、ポリプロピレン、エチレン−プロピレン共重合体などのポリオレフィン系樹脂、ポリスチレン、ＡＢＳ等のスチレン系樹脂、ポリエチレンテレフタレート、ポリブチレンテレフタレート等のポリエステル系樹脂、ポリ塩化ビニル、ポリウレタン等の合成樹脂によって構成される。一方、見切り材（２）は、受け材（１）と同様の樹脂材料によって構成されてもよく、また、木質材料や金属材料によって構成されてもよい。合成樹脂によって構成する場合、通常、受け材（１）及び見切り材（２）は一体的に押出成形される。
【００１２】
受け材（１）は、略帯状の本体の表面に２枚の立上り片（３）が一体的に設けられた構造を備え、帯状本体の幅方向（図面の左右方向）の中央には、長さ方向に一定の間隔で複数のネジ挿通孔（１１）が設けられており、受け材（１）は、ネジ挿通孔（１１）に挿通したネジ（７）によって床下地（９）に固定される様になされている。
【００１３】
本発明においては、見切り材（２）の溝（４）に受け材（１）の立上り片（３）を嵌合させた後は立上り片（３）の溝（４）からの抜けを確実に防止するため、すなわち、見切り材（２）の外れを確実に防止するため、受け材（１）の各立上り片（３）は、互いに基端側から先端側に向かうに従い漸次離間する傾斜状態に設けられる。換言すれば、２つの立上り片（３）は、断面視した場合、逆ハ字状に傾斜した状態に設けられる。
【００１４】
また、各立上り片（３）の仮想垂線に対する傾斜角度（θ）は、５〜３０°に設定されるのが好ましい。傾斜角度（θ）を上記の範囲に設定する理由は次の通りである。すなわち、傾斜角度（θ）を５°よりも小さくした場合には、立上り片（３）の僅かな変形で当該立上り片が見切り材（２）の溝（４）から外れ易く、また、傾斜角度（θ）を３０°よりも大きくした場合には、立上り片（３）を溝（４）に挿入する際、立上り片（３）を一層大きく変形させなければならず、施工性を損なう。なお、図１においては、便宜上、一方の立上り片（３）の傾斜角度（θ）だけを示している。
【００１５】
更に、受け材（１）の各立上り片（３）の外側の壁面、すなわち、受け材（１）の幅方向の外側に面する各立上り片（３）の壁面には、段差（３２）をつけて膨出部（３１）が設けられる。具体的には、各立上り片（３）の上部は、部分的に段差を設けて厚肉に形成される。通常、膨出部（３１）は、立上り片（３）の他の薄肉部の厚さの１０〜５０％だけ薄肉部よりも厚く形成される。
【００１６】
また、受け材（１）の各立上り片（３）の上端部の外側の角部には面取りが施されているのが好ましい。具体的には、立上り片（３）の上端部、すなわち、上記の膨出部（３１）の上部に面取部（３３）が設けられる。立上り片（３）の上端部に面取部（３３）が設けられている場合には、溝（４）に立上り片（３）を挿入する際に後述する見切り材（２）の面取部（４３）に接触させることにより、溝（４）に対してより一層円滑に立上り片（３）を挿入できる。
【００１７】
他方、見切り材（２）は、縦断面を例えば略五角形状に形成されたバー状の本体の底面に２本の溝（４）が設けられた構造を備えており、バー状本体の長手方向（図面において紙面に垂直な方向）に沿った一方の上端角部には、床表面材（８）の小口部分を被覆し且つ押え付ける鍔（２１）が張出されており、また、鍔（２１）と反対側の長手方向に沿った一辺部は、床表面材（８）と床下地（９）との段差を解消して引っ掛かりを防止するため、傾斜した掃出し面（２２）として形成されている。
【００１８】
本発明においては、見切り材（２）の溝（４）に受け材（１）の立上り片（３）を嵌合させる際の施工性を一層高めるため、見切り材（２）の各溝（４）の開口部の外側の角部には面取りが施される。すなわち、見切り材（２）の下面と各溝（４）の外側の内壁面（見切り材（２）の幅方向の外側に位置する溝（４）の内壁面）との角部には、面取部（４３）が設けられる。斯かる面取部（４３）の面の幅は、受け材（１）に見切り材（２）を上方から被せた場合に各立上り片（３）の先端が同時に当接するに足る大きさとされる。
【００１９】
しかも、見切り材（２）の溝（４）に受け材（１）の立上り片（３）を円滑に挿入するため、見切り材（２）の各溝（４）の最小幅（ｗ）は、受け材（１）の各立上り片（３）の最大厚さ（ｔ）よりも大きく設定される。具体的には、溝（４）の最小幅（ｗ）、すなわち、後述する凹部（４１）及び前述の面取部（４３）を除く溝（４）の幅は、立上り片（３）の最大厚さ（ｔ）、すなわち、前述の膨出部（３１）の厚さの１０５〜２００％、好ましくは１１０〜１５０％に設定される。なお、図１においては、便宜上、一方の溝（４）及び立上り片（３）についてのみ上記の最小幅（ｗ）及び最大厚さ（ｔ）を示している。
【００２０】
また、本発明においては、前述の様に、見切り材（２）の溝（４）からの受け材（１）の立上り片（３）の抜けを確実に防止するため、見切り材（２）の各溝（４）は、上記の立上り片（３）の場合と同様に、互いに開口側から奥端側に向かうに従い漸次離間する傾斜状態に設けられる。換言すれば、２つの溝（４）は、断面視した場合、立上り片（３）と同様に逆ハ字状に傾斜した状態に設けられる。そして、好ましくは、各溝（４）の傾斜角度（θ）は、立上り片（３）におけるのと同様に５〜３０°に設定される。
【００２１】
更に、上記の見切り材（２）の各溝（４）の外側の内壁面、すなわち、見切り材（２）の幅方向の外側に位置する各溝（４）の内壁面には、受け材（１）の立上り片（３）の膨出部（３１）が嵌合する凹部（４１）が備えられている。換言すれば、各溝（４）の上記の内壁面には、段差（４２）をつけて凹部（４１）が設けられる。なお、図示する様に、溝（４）の奥端部の外側の角部（凹部（４１）の上部）は、立上り片（３）の面取部（３３）が係合する様に面取りが施されてもよい。
【００２２】
本発明の床見切りを施工する場合には、先ず、図１に示す様に、床表面材（８）の小口に沿わせて床下地（９）に受け材（１）を固定する。次いで、図２に示す様に、上方から見切り材（２）を受け材（１）に被せて下方に押え付ける。その場合、受け材（１）と見切り材（２）を略平行に保持して見切り材（２）を垂直に押え付けてもよいが、例えば、図２に示す様に、見切り材（２）を僅かに傾け、受け材（１）の一方の立上り片（３）の先端部だけを先に見切り材（２）の一方の溝（４）に若干挿入した後、見切り材（２）を水平方向へずらすことにより一方の立上り片（３）を幾分変形させ、そして、他方の立上り片（３）を他方の溝（４）に略一致させて見切り材（２）を押え付けてもよい。
【００２３】
上記の様に、見切り材（２）の溝（４）に受け材（１）の立上り片（３）を相対的に挿入して組み付けるにあたり、見切り材（２）の溝（４）の開口部の外側の角部における面取り構造は、挿入される受け材（１）の立上り片（３）を見切り材（２）の溝（４）の内部へ案内する様に機能し、また、見切り材（２）の溝（４）の最小幅（ｗ）を受け材（１）の立上り片（３）の最大厚さ（ｔ）よりも大きく設定した構造は、溝（４）に対する立上り片（３）の円滑な挿入を可能にする。
【００２４】
換言すれば、本発明の床見切りは、ハンマー等の道具を使用することなく、手先だけの極めて簡単な押込み操作で見切り材（２）の各溝（４）に対して受け材（１）の各立上り片（３）をそれぞれ嵌合させることが出来、その結果、図３に示す様に、受け材（１）に対して見切り材（２）を組み付けて一体化することが出来る。そして、見切り材（２）によって床表面材（８）の小口を覆うと共に床表面材（８）の縁部を鍔（２１）によって押さえることが出来る。
【００２５】
更に、本発明の床見切りにおいては、図３に示す状態に受け材（１）に見切り材（２）を組み付けた場合、受け材（１）の立上り片（３）及び見切り材（２）の溝（４）の傾斜構造、ならびに、立上り片（３）の外側の壁面の膨出部（３１）と溝（４）の外側の内壁面の凹部（４１）との嵌合構造は、立上り片（３）の溝（４）からの垂直方向の抜けを規制し、受け材（１）と見切り材（２）との高い結合力を維持する。従って、見切り材（２）が受け材（１）に一旦組み付けられた後は、外部から不測の力が加わった場合でも、見切り材（２）が容易に外れる虞がない。
【００２６】
また、室内の内装変更などを行う場合、組み付けた見切り材（２）は、図２に示す操作とは逆の操作によって、受け材（１）から取り外すことが出来る。具体的には、見切り材（２）を水平方向へ加圧し、一方の立上り片（３）を幾分変形させて見切り材（２）をずらすことにより、他方の立上り片（３）の膨出部（３１）と溝（４）の凹部（４１）との嵌合を解除した後、見切り材（２）を若干上方へ回動させる様にして持上げることにより、見切り材（２）の各溝（４）から受け材（１）の各立上り片（３）を相対的に引き出すことが出来、見切り材（２）を取り外すことが出来る。
【００２７】
そして、本発明の床見切りにおいては、上記の様に、一旦組み付けた見切り材（２）を受け材（１）から取り外した場合でも、再使用する際に受け材（１）と見切り材（２）の結合機能が損なわれることがない。すなわち、取付や取外しによって立上り片（３）や溝（４）の一部が塑性変形したとしても、上記の傾斜構造および嵌合構造が、受け材（１）に見切り材（２）を再び組み付けた場合に上記の様に高い結合力を発揮するため、見切り材（２）が容易に外れる虞がない。従って、本発明の床見切りは、繰り返して使用することが出来る。
【００２８】
なお、本発明において、見切り材（２）の形状は適宜に設計することが出来、例えば、鍔（２１）と同様の鍔が上端の左右角部に張出された形状に設計することも出来る。斯かる見切り材は、種類の異なる床表面材の端部間の隙間などの処理に使用される。また、受け材（１）の立上り片（３）における膨出部（３１）及び段差（３２）、ならびに、見切り材（２）の溝（４）における凹部（４１）及び段差（４２）は、種々の形状に設計でき、そして、それぞれ複数設けることも出来る。
【００２９】
【発明の効果】
以上説明した様に、本発明の床見切りによれば、見切り材の溝の開口部における面取り構造、および、見切り材の溝の最小幅を受け材の立上り片の最大厚さよりも大きく設定した構造により、極めて簡単な押込み操作で受け材に見切り材を組み付けることが出来、また、受け材の立上り片および見切り材の溝の傾斜構造、ならびに、立上り片の膨出部と溝の凹部との嵌合構造により、施工後における見切り材の外れを有効に防止することが出来、そして、繰り返して使用することが出来る。

[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of a floor parting device according to the present invention will be described with reference to the drawings. Drawing 1 is a figure showing the shape of the receiving material of floor parting and the parting material of the present invention, and is a sectional view perpendicular to the longitudinal direction. FIG. 2 is a cross-sectional view similar to the above, showing the behavior of the part in the assembling operation of the receiving member and the parting material of the floor parting according to the present invention, and FIG. It is sectional drawing similar to the above which shows a state.
[0009]
The floor parting device of the present invention is a building member that covers an edge of a floor surface material such as a floor of a flooring, a carpet or an edge of a carpet, and along the edge of the floor surface material (8) as shown in FIG. It is laid on a floor such as a floor base (9). The floor parting illustrated in the figure is a so-called sweeping parting for treating the end of one floor surface material (8).
[0010]
As shown in FIG. 1, the floor parting device of the present invention has a set of rising pieces (3) protruding in a rail shape on the upper surface and receiving a long object (1) fixed to the floor, and a lower surface on the lower surface. A set of grooves (4) is provided, and a long parting material (2) assembled to the receiving member (1) by relatively inserting the rising pieces (3) into these grooves (4). Be composed. The receiving material (1) and the parting material (2) may be cut into a required length or a plurality of them may be continuously arranged according to the length of the edge of the floor surface material (8) to be treated. used.
[0011]
The receiving material (1) is usually made of a polyamide resin such as polyamide 6, polyamide 6-6, polyamide imide or the like, or polyethylene, in order to elastically deform a rising piece (3) described later when the parting material (2) is assembled to the receiving material (1). , Polyolefin resins such as polypropylene and ethylene-propylene copolymer, styrene resins such as polystyrene and ABS, polyester resins such as polyethylene terephthalate and polybutylene terephthalate, and synthetic resins such as polyvinyl chloride and polyurethane. On the other hand, the parting material (2) may be made of the same resin material as the receiving material (1), or may be made of a woody material or a metal material. When made of a synthetic resin, the receiving material (1) and the parting material (2) are usually extruded integrally.
[0012]
The receiving member (1) has a structure in which two rising pieces (3) are integrally provided on the surface of a substantially band-shaped main body, and a long part is provided at the center of the band-shaped main body in the width direction (left-right direction in the drawing). A plurality of screw insertion holes (11) are provided at regular intervals in the vertical direction, and the receiving member (1) is fixed to the floor substrate (9) by screws (7) inserted into the screw insertion holes (11). It is made to be.
[0013]
In the present invention, after the rising piece (3) of the receiving material (1) is fitted into the groove (4) of the parting material (2), the rising piece (3) is securely removed from the groove (4). In order to prevent it, that is, to surely prevent the parting material (2) from coming off, the rising pieces (3) of the receiving material (1) are in an inclined state in which the rising pieces (3) gradually separate from each other from the base end to the tip end. Provided. In other words, the two rising pieces (3) are provided in a state of being inclined in an inverted C shape when viewed in cross section.
[0014]
Further, it is preferable that the inclination angle (θ) of each rising piece (3) with respect to the virtual perpendicular is set to 5 to 30 °. The reason for setting the inclination angle (θ) in the above range is as follows. That is, when the inclination angle (θ) is set to be smaller than 5 °, the rising piece (3) is easily deviated from the groove (4) of the parting material (2) due to slight deformation of the rising piece (3). When (θ) is larger than 30 °, when the rising piece (3) is inserted into the groove (4), the rising piece (3) must be further greatly deformed, which impairs workability. In FIG. 1, only the inclination angle (θ) of one rising piece (3) is shown for convenience.
[0015]

Furthermore, a receiving material (the inner wall surface of each groove (4) located outside the width direction of the parting material (2), that is, the inner wall surface of each groove (4) located outside the groove (4) of the parting material (2). There is provided a concave portion (41) into which the bulging portion (31) of the rising piece (3) of 1) is fitted. In other words, a recess (41) is provided on the inner wall surface of each groove (4) with a step (42). As shown in the figure, the outer corners (upper portions of the recesses (41)) of the inner ends of the grooves (4) are chamfered so that the chamfers (33) of the rising pieces (3) engage. May be applied.
[0022]
When constructing the floor parting of the present invention, first, as shown in FIG. 1, the receiving material (1) is fixed to the floor base (9) along the fore edge of the floor surface material (8). Next, as shown in FIG. 2, the parting material (2) is placed on the receiving material (1) from above and pressed down. In this case, the receiving material (1) and the parting material (2) may be held substantially parallel to each other, and the parting material (2) may be pressed vertically. For example, as shown in FIG. 2, the parting material (2) Is slightly tilted, and only the tip of one rising piece (3) of the receiving material (1) is slightly inserted into one groove (4) of the parting material (2) first, and then the parting material (2) is leveled. By displacing in the direction, one rising piece (3) may be slightly deformed, and the other rising piece (3) may be substantially aligned with the other groove (4) to press the parting material (2). .
[0023]
As described above, when the rising piece (3) of the receiving material (1) is relatively inserted into the groove (4) of the parting material (2) and assembled, the opening of the groove (4) of the parting material (2). The chamfering structure at the outer corner of the cut-off material (1) functions to guide the rising piece (3) of the receiving material (1) to be inserted into the groove (4) of the cut-off material (2). The structure in which the minimum width (w) of the groove (4) in (2) is set to be larger than the maximum thickness (t) of the rising piece (3) of the receiving material (1) corresponds to the rising piece (3) for the groove (4). Allows for smooth insertion.
[0024]
In other words, the floor parting device according to the present invention does not use a tool such as a hammer, and allows the receiving member (1) to be inserted into each groove (4) of the parting material (2) by a very simple pushing operation using only a hand. Each of the rising pieces (3) can be fitted to each other, and as a result, as shown in FIG. 3, the parting-off member (2) can be attached to the receiving member (1) to be integrated. The edge of the floor surface material (8) can be covered by the flange (21) and the edge of the floor surface material (8) can be covered by the parting material (2).
[0025]
Further, in the floor parting of the present invention, when the parting material (2) is assembled to the receiving material (1) in the state shown in FIG. 3, the rising piece (3) of the receiving material (1) and the parting material (2) are used. The inclined structure of the groove (4) and the fitting structure of the bulging portion (31) on the outer wall surface of the rising piece (3) and the concave portion (41) on the inner wall surface outside the groove (4) are formed by a rising piece. (3) The removal of the vertical direction from the groove (4) is restricted, and a high bonding force between the receiving material (1) and the parting material (2) is maintained. Therefore, once the parting-off member (2) is once assembled to the receiving member (1), there is no possibility that the parting-off member (2) is easily detached even when an unexpected force is applied from the outside.
[0026]
When the interior of the room is changed, the assembled parting member (2) can be removed from the receiving member (1) by an operation reverse to the operation shown in FIG. Specifically, the parting member (2) is pressurized in the horizontal direction, the one rising piece (3) is slightly deformed to shift the parting material (2), and the other rising piece (3) swells. After releasing the engagement between the part (31) and the concave portion (41) of the groove (4), the parting-off member (2) is lifted up by rotating it slightly upward to thereby obtain each parting-off member (2). Each rising piece (3) of the receiving material (1) can be relatively pulled out from the groove (4), and the parting-off material (2) can be removed.
[0027]
In the floor parting of the present invention, as described above, even if the parting-off material (2) once assembled is removed from the receiving part (1), the receiving part (1) and the parting-off part (2) can be reused. ) Is not impaired. That is, even if a part of the rising piece (3) or the groove (4) is plastically deformed by attachment or detachment, the above-described inclined structure and fitting structure re-assemble the parting material (2) to the receiving material (1). In this case, since the high bonding force is exhibited as described above, there is no possibility that the parting material (2) comes off easily. Therefore, the floor parting of the present invention can be used repeatedly.
[0028]
In the present invention, the shape of the parting-off member (2) can be appropriately designed, and for example, a flange similar to the flange (21) can be designed to protrude at the left and right corners of the upper end. . Such a parting material is used for processing such as a gap between the ends of different types of floor surface materials. The bulging portion (31) and the step (32) in the rising piece (3) of the receiving material (1), and the concave portion (41) and the step (42) in the groove (4) of the parting material (2) are: It can be designed in various shapes, and a plurality of each can be provided.
