Description

[Detailed description of the device]

【０００１】［産業上の利用分野］階段等の連続した段差や、連続しない段差での、特に段差の下段から上段へ、重量物や多量の物の運搬に効率化が可能となる。また、車椅子に当考案を用いれば、段差の下段から上段への移動に、スロープは不要となる。[Industrial field of application] It becomes possible to efficiently carry heavy or large amounts of objects in continuous steps such as stairs or in discontinuous steps, particularly from the lower step to the upper step. Further, if the present invention is applied to a wheelchair, a slope is not required for moving from a lower step to an upper step.

【０００２】［従来の技術］最も代表的なものが、動力を用いたキャタピラー方式であり、動力を用いないものとしては、段差の下段から上段への移動に、車輪を複数個組み合わせて一組とした脚一対のみを接地させ、段差の上段方向からカートを引き上げる方式である。[Prior Art] The most typical one is a caterpillar system that uses power. As a system that does not use dynamic power, a plurality of wheels are combined to move from a lower step to an upper step of a step. In this method, only one pair of legs is grounded and the cart is pulled up from the upper direction of the step.

【０００３】［考案が解決しようとする課題］動力によらず、段差よりも大きな径の車輪を用いず、重量物や多量の物を、特に段差の下段から上段に平面上の移動と同等の効率で達成しうること。[Problems to be Solved by the Invention] It is equivalent to moving a heavy object or a large amount of objects, in particular, from a lower stage to an upper stage of a step on a plane without relying on power and without using a wheel having a diameter larger than the step. Can be achieved with the efficiency of.

【０００４】［課題を解決するための手段］請求項１における回転板の進行方向にある副輪が、段差の垂直面に当たった時、梶棒を押し下げ、続いて、梶棒を進行方向に押すことで、脚に組みつけた、主輪と回転板の軸が、接地している副輪の軸を中心に、段差の上段方向に向けた円運動を起こし、主輪を段差の上段に乗せる。垂直移動を弧移動に変えることで、効率的に段差を通過する。[Means for Solving the Problem] When the auxiliary wheel in the traveling direction of the rotating plate in claim 1 hits the vertical surface of the step, the clerk is pushed down, and subsequently the clerk is pushed in the traveling direction. Then, the shaft of the main wheel and rotating plate mounted on the leg makes a circular motion toward the upper step of the step centering on the axis of the auxiliary wheel that is in contact with the ground, and puts the main wheel on the upper step of the step. By changing vertical movement into arc movement, it efficiently passes through the steps.

【０００５】［作用］平面でのカートによる、重量物や多量の物の運搬と同程度の効率で、階段等連続した段差や、単独の段差を、段差よりも大きな径の車輪を用いることなく、特に下段から上段へ運搬又移動が可能となる。[Operation] With the same level of efficiency as carrying a heavy object or a large amount of a flat cart, a continuous step such as stairs or a single step can be performed without using a wheel having a diameter larger than the step. Especially, it can be transported or moved from the lower stage to the upper stage.

【０００６】［実施例］階段や段差のある床面で、重量物や多量の物を運搬するカート。スロープの設けられていない段差を移動しうる車椅子。[Embodiment] A cart for carrying heavy or large amounts of goods on stairs or floors with steps. A wheelchair that can move on steps without slopes.

【０００７】［考案の効果］カートによる重量物や、多量の物の運搬において、特に段差の下段から上段に平面移動の場合とほぼ同等の効率が得られ、また、車輪の直径と、越えうる段差に相互関係はなくなる。[Advantages of the Invention] When carrying a heavy load or a large amount of load with a cart, the efficiency is almost the same as in the case of plane movement from the lower stage to the upper stage of the step, and the diameter of the wheel and There is no interrelationship between the uneven steps.
