Title (EN) PUSHCART
(FR) CHARIOT
(JA) 台車
Abstract:
(EN) The pushcart (1) has multiple casters installed on the bottom surface of a loading platform (10). At least one of the multiple casters is a universal caster (30) capable of swiveling with respect to the loading platform (10) so as to change the traveling direction of the pushcart (1). The universal caster (30) is attached to an attachment surface (45) disposed between a traveling surface (F), on which a wheel of the universal caster (30) travels, and the bottom surface of the loading platform (10). The wheel of the universal caster (30) is lifted from the traveling surface (F) by a lifting mechanism (60). When the wheel is lifted from the traveling surface (F) by the lifting mechanism (60), the attachment surface (45) is changed by a posture changing mechanism (42) from a parallel position parallel to the bottom surface of the loading platform (10) to a tilted position tilted with respect to the loading platform (10). The tilted position of the attachment surface (45) is retained by a retaining mechanism (46, 52) and is released by a releasing mechanism (18).
(FR) L'invention concerne un chariot (1) comportant de multiples roulettes installées sur la surface inférieure d'une plate-forme de chargement (10). Au moins l'une des multiples roulettes est une roulette universelle (30) apte à pivoter par rapport à la plate-forme de chargement (10) de façon à modifier la direction de déplacement du chariot (1). La roulette universelle (30) est fixée à une surface de fixation (45) disposée entre une surface de déplacement (F), sur laquelle se déplace une roue de la roulette universelle (30), et la surface inférieure de la plate-forme de chargement (10). La roue de la roulette universelle (30) est soulevée de la surface de déplacement (F) par un mécanisme de levage (60). Lorsque la roue est soulevée de la surface de déplacement (F) par le mécanisme de levage (60), la surface de fixation (45) est modifiée par un mécanisme de changement de position (42) d'une position parallèle, parallèle à la surface inférieure de la plate-forme de chargement (10), à une position inclinée, inclinée par rapport à la plate-forme de chargement (10). La position inclinée de la surface de fixation (45) est maintenue par un mécanisme de retenue (46, 52) et est libérée par un mécanisme de libération (18).
(JA) 台車(1)は、荷台(10)下面に設けられる複数のキャスターを有する。複数のキャスターの少なくとも1つは、台車(1)の進行方向を変更するように荷台(10)に対して旋回可能な自在キャスター(30)である。自在キャスター(30)は、自在キャスター(30)の車輪が走行する走行面(F)と荷台(10)の下面との間に設けられた取付面(45)に取付けられる。自在キャスター(30)の車輪は、昇降機構(60)によって走行面(F)から持ち上げられる。昇降機構(60)が車輪を走行面(F)から持ち上げる際に、取付面(45)が姿勢変更機構(42)によって荷台(10)下面と並行である並行位置から荷台(10)下面に対して傾斜した傾斜位置へ変更される。取付面(45)の傾斜位置が保持機構(46,52)によって保持され、解除機構(18)によって解除される。
