ANTI-BACKLASH RACK AND PINION GEAR IN TRIPLE SLIDING DOOR SYSTEM
To prevent the occurrence of backlash and to prevent the wear of either one of rack or pinion teeth without the need for forming a groove on either one of the rack or pinion teeth.SOLUTION: There are provided a first opening/closing door disposed on the upper frame side as an automatic door mounting frame, a second opening/closing door disposed next to the first opening/closing door on the side away from the upper frame, a second rail and a second suspension fitting structure which enable the second opening/closing door to open and close freely in the extention direction, and a rack and pinion gear structure which interlocks the first opening/closing door and the second opening/closing door. The rack and pinion gear structure consists of an upper rack gear, a lower rack gear, and a pinion gear. Between an upper rack gear fixing portion for fixing the upper rack gear and a lower rack gear fixing portion of the lower rack gear fixing base for fixing the lower rack gear, an elastic member is provided to press-contact the upper rack gear fixing portion and the lower rack gear fixing portion.SELECTED DRAWING: Figure 5
【課題】ラックまたはピニオンのいずれか一方の歯群に筋溝加工を施す必要がなく、バックラッシュの発生を防止し、ラックまたはピニオンのいずれか一方の歯群が摩耗するのを防止することのできるようにする。【解決手段】自動ドア取付枠としての上枠の側に配置される第一開閉ドアと、上枠から離れる側の第一開閉ドアの隣に配置される第二開閉ドアと、第二開閉ドアを延在方向に開閉動自在にする第二レール及び第二吊り金具構造部と、第一開閉ドア及び前記第二開閉ドアを連動させるラック・ピニオンギア構造部とを備え、ラック・ピニオンギア構造を上側ラックギアと、下側ラックギアと、ピニオンギアで構成し、上側ラックギアを固定する上側ラックギア固定部と、下側ラックギアを固定する下側ラックギア固定ベースの下側ラックギア固定部との間に、上側ラックギア固定部と下側ラックギア固定部とに圧接するように弾性部材を設ける。【選択図】図５
