Abstract
(EN) The present invention provides an inclination-adjustable cart apparatus comprising: a loading plate on which an object is loaded; a frame supported and fixed to one side of the loading plate and having a handle on the top side thereof so that same may be gripped by a hand; and wheels installed at the front and rear of the lower part of the loading plate so as to guide the movement thereof, wherein the wheels are divided into a front wheel part and a rear wheel part, and the front wheel part and the rear wheel part may be simultaneously lifted/lowered by means of a wheel shaft or a support plate, wherein the wheel shaft or the support plate is coupled to the bottom end of a lifting/lowering means, and the top end part of the lifting/lowering means is coupled to the bottom surface of the loading plate, wherein the lifting/lowering means is driven by a control part which is provided with a gyro sensor, and thus the loading plate may always be maintained in a horizontal state, regardless of a slope of a ground surface. The effect of the present invention is that the gyro sensor is provided to the cart so as to measure a slope, and by using same, the shaft heights of the front wheels and the rear wheels may be adjusted according to a slope of a road, and thus the cart loading plate for loading and transporting an object may always be maintained in a horizontal state, regardless of the slope of the road, and thus the present invention is very useful in that the object may be stably or conveniently transported without being separated from the cart loading plate, i.e., a cargo box.
(FR) La présente invention concerne un appareil de chariot à inclinaison réglable comprenant : une plaque de chargement sur laquelle est chargé un objet; un cadre supporté et fixé à un côté de la plaque de chargement et ayant une poignée sur son côté supérieur de telle sorte qu'il peut être saisi par une main; et des roues installées à l'avant et à l'arrière de la partie inférieure de la plaque de chargement de façon à guider leur mouvement, les roues étant divisées en une partie de roues avant et en une partie de roues arrière, et la partie de roues avant et la partie de roues arrière pouvant être simultanément soulevées/abaissées au moyen d'un essieu ou d'une plaque de support, l'essieu ou la plaque de support étant couplé(e) à l'extrémité inférieure d'un moyen de levage/abaissement, et la partie d'extrémité supérieure du moyen de levage/abaissement est couplée à la surface inférieure de la plaque de chargement, le moyen de levage/abaissement étant entraîné par une partie de commande qui est pourvue d'un capteur gyroscopique, et la plaque de chargement pouvant ainsi toujours être maintenue à l'horizontale, quelle que soit la pente d'une surface de sol. L'effet de la présente invention est que le capteur gyroscopique est disposé sur le chariot de façon à mesurer une pente, et à l'aide de celui-ci, les hauteurs d'essieu des roues avant et des roues arrière peuvent être ajustées en fonction de la pente d'une route, et ainsi la plaque de chargement de chariot pour charger et transporter un objet peut toujours être maintenue à l'horizontale, quelle que soit la pente de la route, et ainsi la présente invention est très utile en ce que l'objet peut être transporté de façon stable ou pratique sans être séparé de la plaque de chargement de chariot, c'est-à-dire, une caisse.
(KO) 본 발명은 물건이 적재되는 적재판과, 상기 적재판의 일측에 지지고정되며 상측에 손으로 잡을 수 있도록 하는 손잡이가 구비된 프레임과, 상기 적재판의 하부 전후방에 장착되어서 이동을 안내하는 바퀴로 이루어지되, 상기 바퀴는 전방 바퀴부와 후방 바퀴부로 나누고 상기 전방 바퀴부와 후방 바퀴부는 바퀴축 또는 지지판에 의해 동에 승하강 가능토록 하는 카트장치에 있어서, 상기 바퀴축 또는 지지판은 승하강수단의 하단에 결합되도록 하고,승하강수단의 상단부는 적재판의 저면에 결합되도록 하되, 상기 승하강수단은 자이로센서를 구비하는 제어부에 의해 구동되어 적재판이 지면의 경사와는 상관없이 항상 수평상태를 유지할 수 있도록 구성되는 경사 조절가능한 카트장치를 제공하기 위한 것으로, 본 발명의 효과로는 카트에 자이로센서로 장착하여 경사도를 측정하고 이를 이용해 앞바퀴와 뒷바퀴의 축의 높낮이를 도로의 경사에 맞춰 조절함으로써 물건을 적재하여 실어나르는 카트의 적재판이 도로의 경사에 상관없이 항상 수평을 유지할 수 있도록 하여 카트 적재판, 즉 적재함으로부터 물건의 이탈됨 없이 안정적으로, 또 편리하게 물건을 나를 수 있는 매우 유용한 발명인 것이다.
