また、本体または移動体の一方に取り付けられるケース、前記ケースに摺動自在に配されたスライダー、前記スライダーに枢支されてケース対応部に係止する待機姿勢と前記係止を解除する引込姿勢とに切り換えられるラッチ、及び付勢手段を有する引込ユニットと、前記本体または移動体の他方に取り付けられて前記ラッチを待機姿勢から引込姿勢に切り換え、または引込姿勢から待機姿勢に切り換える作動部材とを備え、前記ラッチが待機姿勢から引込姿勢に切り換えられると、前記付勢手段に蓄積されていた付勢力により、前記移動体を、前記作動部材を介して本体側の第1位置から第2位置へ移動可能にする摺動補助装置であって、前記ラッチと前記スライダーとの摺接面に設けられて、前記ラッチが前記スライダーに対して枢支部を支点として回動されるときに抵抗ないしは摩擦力として働く抵抗付与部を備えることを特徴とする摺動補助装置。
また、上記(2)の摺動補助装置において、前記抵抗付与部は、前記ラッチ及び前記スライダーの少なくとも一方の摺接面に設けられた凸部または凹凸部からなる構成である。
また、前記移動体の付勢力で移動される速度を制動するピストン式の制動手段5を有し、前記スライダー又は前記ケースに設けられて前記制動手段の構成部材を仮止めする仮止め部材、及び前記スライダー又は前記ケースに係合されることで前記制動手段の構成部材を本止めする取付部材を備えることを特徴とする摺動補助装置。
なお、この摺動補助装置は、ピストン式制動手段の構成部材のうち、特に径小となるピストンロッドの固定構造に好適であり、ピストンロッドを一旦仮止めした状態から、スライダー又はケースに対する取付部材の係合操作により本止めする。
本実施形態に係る摺動補助装置は、本体7または引戸や扉などの移動体(以下、扉Aの例で説明する)の一方に取り付けられる引込ユニット6と、本体7または扉Aの他方に取り付けられる突起体8とを備える。なお、扉Aは、摺動補助装置の取付対象である移動体の一例であり、突起体8は、本発明における作動部材の一例である。また、本例では、引込ユニット6を本体7に取り付け、突起体8を扉Aに取り付けた場合を示すが、引込ユニット6を扉Aに取り付け、突起体8を本体7に取り付けることも可能である。また、引込ユニット6及び突起体8の構成は、取り付けられる移動体や引き込み作動設定により次の3種類に大別される。
引込ユニット6のケース1は、細長い略直方体形状の部品であり、下面11と両側面12と左右の端部13aで区画された内部空間10を有し、内部空間10の上側には開口が設けられている。また、上記開口は、カバー15で覆われている。また、ケース1における内部空間10の左右には、ケース1を本体7へ取り付けるための取付部10aが設けられている。また、端部13aは、ケース1の長手方向における端部13よりも外側で内部空間10を区画しており、この端部13aの内面にコイルスプリング3の延長部3bが当接する。下面11には、幅方向の中間部に長手方向に沿って形成されたガイド孔11aと、ガイド孔11aの両縁部よりも一段低く形成されているガイド部11bとが設けられている。ガイド溝11cは、一方の側面12の内側に沿って形成された浅い凹状の溝であり、スライダー2A,2B及びコイルスプリング3の一部を位置決めする。ガイド溝11dは、制動手段5としてピストンダンパを構成しているシリンダー50をケース1内で摺動し易くする凹部である。符号11eは、ラッチ4の下面に設けられた凸部48と嵌合するガイド溝である。
突起体8は、本発明における作動部材の一例であり、移動体の一例である扉Aに対し付勢力を介して出没自在、つまり負荷を受けると付勢力に抗して突出量を減じる構成である。本例は、本出願人の先願である日本国特許出願公開第2011-001781号公報に記載されているものであり、扉Aの上端部に取り付けられるケース8aと、ケース8a上に突出して扉Aを固定側ガイドレールに沿って案内するガイド軸8bと、ガイド軸8bをケース8aの幅方向に移動調整する調整機構として、ケース8aに設けられた横穴8cに配置されて外部から回動操作可能な調整用部材8dと、調整用部材8dの回動によりケース8a内を進退してガイド軸8bを幅方向に移動調整する不図示の調整部材などを有している。勿論、突起体8としては、これに限られず、例えば、日本国特許出願公開第2007-107301号公報に開示されているガイド軸構成又はそれに類似する構成でもよい。
以上の各部材は、例えば、以下のように組み立てられる。すなわち、まず、各ラッチ4をスライダー2A,2Bに枢支した後、スライダー2A,2B同士を制動手段5であるピストン式ダンパー及びコイルスプリング3を介して連結する。次に、それらをケース1に組み入れ、かつケース1にカバー15を取り付けることで引込ユニット6となる。
次に、図11(a)および図11(b)に示す扉Aに適用した場合の要部作動について説明する。
B)上記規制手段9は、支軸側の径大頭部41bを支持溝27の段差27a、或いは、支持溝37の段差37aに受け止めることにより、スライダー2A,2Bに対するラッチ4の正常な姿勢を確実に保つ。
D)しかも、上記枢支構造では、ラッチ4の待機姿勢において、そのラッチ4を枢支しているスライダー2Aがケース空間部10を区画している端部13aに対し付勢手段3の延長部3bが当接しているので、スライダー2Aが振動や衝撃を受けても延長部3bが振動ないしは衝撃吸入作用により影響を受けに難くなっている。
F)ラッチ4の枢支構造では、ラッチ4が待機姿勢から作動部材である突起体8を介して引込姿勢に切り換えられるときに発生する切換音を、上記したDカットやHカットの形状によりラッチが低速回動されるようにして低減できるようにする。
