Definitions
- the present invention relates to a cover mounting structure in which a cover member is mounted on the surface of a base, and a cover mounting method for the cover mounting structure.
- a cover member there are some which have a surface protection or antifouling function by attaching a cover member to a portion where scratches or wear marks may occur on the surface of the substrate due to contact or rubbing with other members.
- a desired cover member may be attached and decorated at a site where the appearance of the substrate surface is required, or the cover member attached to the substrate may be replaced for a new tone.
- a steering cover (cover member) made of natural leather, artificial leather, or the like attached to a steering wheel of an automobile (see Patent Documents 1 and 2).
- the end of the cover member is inserted into a groove formed in advance in the base, and the end is bonded within the groove.
- the bonding process of the cover member becomes complicated, and a long processing time is required until the cover member is completely fixed.
- the cover member once attached to the base body cannot be removed from the base body, there is a disadvantage that the cover member cannot be cleaned or replaced.
- the cover member can be easily attached to and detached from the base body by a fastener with a slider provided at the end of the cover member.

Abstract
Description
一方、特許文献2の構成においては、カバー部材の端部に設けられたスライダー付きファスナーにより、カバー部材を基体への取り付け取り外しが容易に行える構成になっている。すなわち、カバー部材を、基体に巻き付けてカバー部材の端部同士をスライダー付きファスナーで接合することで、基体に固定している。これにより、基体表面が簡単にカバー部材で覆われる。
ところが、特許文献2の構成のようなファスナーを用いてカバー部材を基体に取り付ける場合、図17(A)に示すように、ファスナーエレメント215が、基体211を覆うカバー部材213上で露出して、突起部217が形成される。また、図17(B)に示すように、上記したカバー部材213を表裏反転させた場合も同様に、ファスナーエレメント215による突起部217が形成されてしまう。この突起部217は、手で触れた際の異物感や、外観不良を生じさせるため、形成させないことが好ましい。そこで、図17(C)に示すように、基体211に予め形成された凹溝219にファスナーエレメント215を収容して、基体外側に突起させないようにすることが考えられる。
しかし、凹溝219に収容されたファスナーエレメント215は、その周囲にスライダーが通過可能な隙間を設けておく必要がある。そのため、凹溝219は、ファスナーエレメント215の周囲にスライダーを通過させるための余分な隙間空間が形成された、幅広且つ深底の溝となる。このような広幅で深底の凹溝219では、カバー部材213のファスナーエレメント215が定位置で係止されにくい。また、凹溝219よりもファスナーエレメント215が比較的小さいために、カバー部材213が横ずれしやすくなる。

次に、上記したカバー取付構造体100の実際の適用例について説明する。まず、カバー取付構造体を自動車等のステアリングホイールに取り付けられるホイールカバーに適用した例を示す。
ステアリングホイール61は、ボス部63と、ボス部63から径方向に延出されるスポーク部65と、スポーク部65の径方向外側に連結されるリング部67とを有する。
図14は、治具を用いて前述のステアリングホイール61のリング部67にカバー部材73を取り付ける様子を示す説明図である。
治具89は、U字部を有した一対のフレーム93,95を有する。一対のフレーム93,95は、U字部93a,95aの一端側に形成された支軸90で連結され、支軸90を中心とする回転動作によってU字部93a,95aの他端側が開閉される。フレーム93,95は、閉状態において矩形状の環状領域が形成される。この環状領域にリング部67を挟んだ状態で、U字部93a,95aの他端側が図示しないボルト等の締結部材によって閉じられる。
次に、カバー取付構造体の他の適用例を説明する。
上記したカバー取付構造体は、ステアリングホイールに限らず、基体表面をカバー部材で覆う構造体であれば適用可能である。他の適用例として、例えば、次の応用事例が挙げられる。
椅子の座部や背もたれ部を覆う生地の端部等に、本構成のカバー取付構造体を適用することで、椅子の生地を交換可能な構成にできる。この場合、カバー部材である生地を座部や背もたれ部に巻き付けることもできるが、カバー部材の取り付け部位によっては、複数枚のカバー部材を組み合わせて用いる方がよい場合もある。その場合には、図15に示すように、一枚のカバー部材111に設けた一方のエレメント列113を凹溝115に挿入し、他のカバー部材117のエレメント列119と噛合頭部同士を噛合させる。また、他方のエレメント列121を凹溝123に挿入し、他のカバー部材125のエレメント列127と噛合頭部同士を噛合させる。つまり、一枚のカバー部材111の両端における側縁に沿って、ファスナーエレメントを取り付ける。続いて、異なるカバー部材117の側縁に沿って取り付けられたファスナーエレメントを、先ほどのカバー部材111のファスナーエレメントに対して対向して配置し、特定の凹溝115に収容させる。また、異なるカバー部材125の側縁に沿って取り付けられた別のファスナーエレメントが、カバー部材111の別のファスナーエレメントに対向して配置し、先ほどの凹溝115とは異なる位置に備える別の特定の凹溝123に収容される。これにより、一枚のカバー部材111が異なる位置の凹溝115,123に固定され、各カバー部材111,117,125によって基体128の表面が覆われる。換言すれば、同一位置の凹溝115,123には、互いに異なるカバー部材111,117,125のファスナーエレメントがそれぞれ収容される。
例えば、自動車のルーフライニング(カバー部材)においては、天井面に設けたアシストグリップの周辺のライニングが手との接触により汚れることがある。そこで、ルーフ面のアシストグリップ周辺を取り囲む所定の領域を、本構成のカバー取付構造体として、ライニングを交換可能にする。
住宅や店舗をはじめ、駅や病院等の公共施設等、建築物の屋内外の壁面、天井面、床面にも本構成のカバー取付構造体を適用できる。例えば、壁面に設ける壁紙を、壁全体、又は部分的に交換することで、特に汚れが目立つ部位を新調することや、壁面を所望の色、模様、材質の異なるもの等に変更することを自由に行える。カバー部材の交換は、前述の図15,図16に示すカバー部材のように着脱自在としてもよく、一枚又は複数枚のカバー部材により、基体表面の一部又は全体を覆うようにしてもよい。
