Description

本発明は、階段に踏み板に関する。 The present invention relates to a tread on a staircase.

従来、住宅の階段の踏み板には、踏み板本体が木質製のものが使用されている。しかし、最近、汚れなどを防ぐために踏み板本体の表面を化粧シートで覆った踏み板も普及している。（特許文献１を参照）。 Conventionally, a tread board body made of wood is used as a tread board of a staircase in a house. However, recently, a tread board in which the surface of the tread board body is covered with a decorative sheet in order to prevent dirt and the like has become widespread. (See Patent Document 1).

ここで、階段は、多数の踏み板からなっているが、踏み板本体の表面が化粧シートで覆われた踏み板を使用した場合、各踏み板の表面の化粧シートは色も模様も略同様であることが多く、人が階段を上がり下がりする場合に各踏み板の境目がわからないで、踏み誤ることがある。特に、視力が弱くなった高齢者は階段で踏み板を踏み外して怪我をすることがある。 Here, the staircase is composed of a large number of footboards. However, when a footboard whose surface is covered with a decorative sheet is used, the decorative sheet on the surface of each footboard may have substantially the same color and pattern. In many cases, when a person goes up and down stairs, he or she does not know the boundary between each tread board and may make a mistake. In particular, elderly people with weak vision may be injured by stepping off the footboard on the stairs.

踏み外し事故を防ぐ等のために、階段の各踏み板の長手方法中央部に目印を設けた踏み板が開発されている（例えば、特許文献２参照）。
特許２００３-１１９９８４号公報特開２００１−３３６２６２号公報 In order to prevent a stepping accident and the like, a footboard having a mark at the center of the longitudinal direction of each footboard of a staircase has been developed (for example, see Patent Document 2).
Japanese Patent No. 2003-119984 JP 2001-336262 A

しかし、本発明者は、各踏み板の中央部だけに目印を設けるのは不十分だと考えて、長さが各踏み板の長手方向の全長にわたる目印を設けることを試みた。そして、目印として、簡単な構造で目印としても十分に役立つように、各踏み板本体の表面の前側の側端部に沿って溝を形成してみた。しかし、踏み板の表面を化粧シートで覆うと、溝も隠れてしまい、溝が目印としての役目を果たさなくなった。そこで、溝が隠れないように、化粧シートを踏み板本体に貼り付けた後に、カッタなどで化粧シートごと踏み板本体を削って溝を形成したり、化粧シートをその一側端面が踏み板に予め形成された溝の上側の角に合致するように当該シートを張ってみた。こうすることにより、踏み板本体の溝も隠れなくなり、各踏み板の境目もはっきりとわかるようになり、踏み外し事故も防げるかに思えた。 However, the present inventor considered that it is insufficient to provide a mark only in the center portion of each tread board, and attempted to provide a mark whose length covers the entire length in the longitudinal direction of each tread board. And as a mark, it tried to form a groove along the front side edge part of the surface of each tread board main body so that it may serve as a mark sufficiently with a simple structure. However, when the surface of the tread board was covered with a decorative sheet, the groove was also hidden, and the groove no longer served as a landmark. Therefore, after sticking the decorative sheet to the footboard body so that the groove is not hidden, the groove is formed by cutting the footboard body together with the decorative sheet with a cutter or the like, or one end face of the decorative sheet is formed in advance on the footboard The sheet was stretched to match the upper corner of the groove. By doing this, the groove of the tread board itself was not hidden, the boundary between each tread board became clear, and it seemed that accidents caused by stepping off could be prevented.

ここで、踏み板本体に化粧シートを貼った後は、そのままの状態で塗装もしないて実験を続けて行った。しかし、踏み板の化粧シートが、溝の上部の角に合致する側端面から剥がれてしまうという事態が起こった。かかる事態が起こると、見栄えも悪くなるし、剥がれた部分が障害物となって、階段を使う人の足にひっかかって危険である。このような事態が起こらないように、化粧シートを踏み板に貼り付けた後に、当該シートの上から塗装してみた。これにより、塗料が接着剤の役目を果たし、化粧シートが剥がれる事態は生じなくなったが、塗装作業は面倒で手間もかかりコストも嵩むことになった。 Here, after applying the decorative sheet to the main body of the tread board, the experiment was continued without painting as it was. However, a situation occurred in which the decorative sheet of the tread board was peeled off from the side end face that coincided with the upper corner of the groove. When such a situation occurs, it looks bad, and the peeled portion becomes an obstacle, and it is dangerous to catch on the feet of people who use the stairs. In order to prevent such a situation from occurring, after applying the decorative sheet to the tread board, the paint was applied from above the sheet. As a result, the paint serves as an adhesive and the decorative sheet does not peel off. However, the painting work is cumbersome, time-consuming, and expensive.

本発明の目的は、コストを低く抑えることができ、かつ、踏み外し事故も防げる階段の踏み板を提供することにある。 SUMMARY OF THE INVENTION An object of the present invention is to provide a step board for a staircase that can keep costs low and prevent accidents caused by stepping off.

上記目的を達成するために、本発明は、表面の前側の側端部に沿って目印の溝が形成された踏み板本体と、この踏み板本体の表面を覆いかつその一側端面が前記溝の上側の角に合致する化粧シートとを備え、下端部が前記踏み板本体の溝に嵌まり込み上端部に前記化粧シートの側端面を上から覆って押圧可能な鍔部を有する押さえ部材を設けたことを特徴とする構成である。 In order to achieve the above object, the present invention provides a tread plate body in which a groove for a mark is formed along a front side end portion of the surface, and covers the surface of the tread plate body, and its one end surface is an upper side of the groove. And a pressing member having a flange that can be pressed by covering the side end surface of the decorative sheet from above and fitting the lower end into the groove of the footboard body. It is the structure characterized by these.

上記本発明の場合、踏み板本体に化粧ジートを貼り付けた後は塗装しないので、塗装しない分コストも低く抑えることができる。そして、押さえ部材によって化粧シートの剥がれもなくなった。 In the case of the above-mentioned present invention, since the paint is not applied after the makeup sheet is attached to the tread board body, the cost can be kept low by the amount not applied. And the decorative sheet was not peeled off by the pressing member.

本発明によればコストも低く抑えることができ、押さえ部材によって化粧シートの剥がれもなくなった。 According to the present invention, the cost can be kept low, and the decorative sheet is not peeled off by the pressing member.

以下、本発明の実施の形態を図面を参照しながら説明する。 Embodiments of the present invention will be described below with reference to the drawings.

本発明に係る階段の踏み板は、図1〜図４にしめすように、表面の前側の側端部１８に沿って目印の溝１９が形成された踏み板本体１０と、この踏み板本体１０の表面を覆いかつその一側端面（１５ａ，１５ｂ）が溝１９の上側の角（1９ａ，１９ｂ）に合致する化粧シート１５とを備え、下端部２１が踏み板本体１０の溝１９に嵌まり込み上端部２２に化粧シート１５の側端面（１５ａ，１５ｂ）を上から覆って押圧可能な鍔部（２３，２３）を有する押さえ部材２０を設けた構成とされている。 As shown in FIGS. 1 to 4, the step board of the staircase according to the present invention includes a tread board body 10 having a mark groove 19 formed along a side edge 18 on the front side of the surface, and a surface of the tread board body 10. And a decorative sheet 15 having one end face (15a, 15b) that coincides with the upper corner (19a, 19b) of the groove 19 and a lower end portion 21 fitted into the groove 19 of the footboard body 10 and an upper end portion 22 The pressing member 20 having the flanges (23, 23) that can be pressed by covering the side end surfaces (15a, 15b) of the decorative sheet 15 from above is provided.

この実施形態では、踏み板本体１０は、合板１１とＭＤＦ（１２，１２）とから形成されている。化粧シート１５は、シート状のオレフィン材（厚さは０．１６ｍｍ）から形成されている。この実施形態では、化粧シート１５は、図５に示すように、踏み板本体１０の表面に貼り付けられた後に、図６に示すようにカッタ５０で当該シート１５ごと当該踏み板本体１０の表面が所定深さに削られる。この化粧シート１５は、図３に示す短辺方法長さは、踏み板本体１０の短辺方法長さと同じに形成されている。しかし、図７に示すように、その短辺方法長さを踏み板本体１０の短辺方法長さと所定長さだけ長く取り、その端部（１５ａ，１５ｂ）が踏み板本体１０の裏面側に達するようにしてもよい（このような、作業をラッピングという）。このラッピングをすることにより、踏み板本体１０の前側端面が化粧シート１５で隠れることになり、見栄えも一層良くなる。また、階段を使用する人の足が引っかかることも完全に解消される。また、化粧シート１５も端から剥がれるようなことも完全になくなる。なお、この際、化粧シート（１５）を踏み板本体１０に貼り付けた後に、当該シート（１５）をその一側端面が踏み板本体１０に予め形成された溝（１９）の上側の角（１９ａ，１９ｂ）に合うように当該シート（１５）を張ってもよい。 In this embodiment, the footboard body 10 is formed of a plywood 11 and MDF (12, 12). The decorative sheet 15 is formed from a sheet-like olefin material (thickness is 0.16 mm). In this embodiment, the decorative sheet 15 is attached to the surface of the footboard body 10 as shown in FIG. 5, and then the surface of the footboard body 10 together with the sheet 15 is predetermined by the cutter 50 as shown in FIG. 6. Sharpened to depth. The decorative sheet 15 has the short side method length shown in FIG. 3 that is the same as the short side method length of the footboard body 10. However, as shown in FIG. 7, the short side method length is made longer by a predetermined length than the short side method length of the tread board body 10, and the end portions (15 a, 15 b) reach the back side of the tread board body 10. You may do it (this kind of work is called wrapping). By this lapping, the front side end face of the tread board main body 10 is hidden by the decorative sheet 15, and the appearance is further improved. In addition, it is completely eliminated that a person using the stairs gets caught. Further, the decorative sheet 15 is completely prevented from being peeled off from the end. In this case, after the decorative sheet (15) is attached to the footboard body 10, the sheet (15) is attached to the upper corner (19a, 19a, The sheet (15) may be stretched to meet 19b).

また、押さえ部材２０は、軟質系樹脂から形成されており、その下端部２１には当該部材２０が外に抜け出すのを完全に防ぐための返し部（２５，２６）が形成されている。この押さえ部材２０が上記した溝１９の代わりに目印としての役目を果たす。この押さえ部材２０は、化粧シート１５の一側端（１５ａ，１５ｂ）を上から押圧して当該側端（１５ａ，１５ｂ）が剥がれるのを阻止する。この実施例では、その長手方向長さＬ１（図１中では紙面と直角方向、図２（Ａ）では左右方向）は、図４に示す踏み板本体１０の長手方向長さＬ０相当とされている。押さえ部材２０は、化粧シート１５と色相または明暗を違えたほうが目印として特に役立つ。 The pressing member 20 is made of a soft resin, and a return portion (25, 26) for completely preventing the member 20 from slipping out is formed at the lower end portion 21 thereof. The pressing member 20 serves as a mark instead of the groove 19 described above. The pressing member 20 presses one side end (15a, 15b) of the decorative sheet 15 from above to prevent the side end (15a, 15b) from peeling off. In this embodiment, the length L1 in the longitudinal direction (the direction perpendicular to the paper surface in FIG. 1, the left-right direction in FIG. 2A) corresponds to the length L0 in the longitudinal direction of the footboard body 10 shown in FIG. . The pressing member 20 is particularly useful as a mark when the hue or brightness is different from that of the decorative sheet 15.

本踏み板は、上記した構成であるから、踏み板本体１０に化粧ジート１５を貼り付けた後は塗装しないので、塗装しない分コストも低く抑えることができる。そして、押さえ部材２０に簡単な構成である、これによって化粧シート１５の剥がれもなくなった。また、押さえ部材２０が踏み板本体１０の溝１９の目印としての役目を更に補強するので、当本踏み板を使用することにより、各踏み板の境目も一層名作になり踏み外し事故を有効に防止できる。また、押さえ部材２０は、軟質系樹脂で形成されており、滑り止めの効果も期待される。これにより、一段と、各踏み板の踏み外し事故も完全に防止できる。 Since the present footboard has the above-described configuration, it is not painted after the makeup sheet 15 is attached to the footboard body 10, so that the cost can be kept low due to the absence of painting. And the pressing member 20 has a simple configuration, and thus the decorative sheet 15 is not peeled off. Further, since the pressing member 20 further reinforces the role as a mark of the groove 19 of the footboard main body 10, the use of the present footboard makes the border of each footboard more masterpiece and effectively prevents accidents. Further, the pressing member 20 is formed of a soft resin, and an anti-slip effect is also expected. As a result, it is possible to completely prevent accidents where each treadle is stepped off.
