考案の詳細な説明Detailed description of the invention
考案が解決しようとする課題Issues that the device is trying to solve
車軸より低くシャーシーを設ける事は出来ず、或る空間を開けなければ路面との摩擦で車は走行もできない。この為、車の床は路面とは並行とならず、車椅子を搭載する場合には、その間の段差を橋渡しする滑り板を設ける必要があった。あるいは、二重床を用い、複雑に折曲がりする腕や伸縮機能を装備して、上部の床が車体よりせり出し、路面へ着地する電動リフトの福祉車両もあるが。この複雑な装備の電動リフトを簡素化し、車体からはみ出ず、勾配もなく、車の床が路面に着地し、車椅子を手軽に搬入できる考案である。The chassis cannot be provided lower than the axle, and the vehicle cannot travel due to friction with the road surface unless a certain space is opened. For this reason, the floor of the car is not parallel to the road surface, and when a wheelchair is mounted, it is necessary to provide a sliding plate that bridges a step between them. Alternatively, there is a welfare vehicle with an electric lift that uses a double floor, is equipped with a complex bending arm and a telescopic function, and the upper floor protrudes from the vehicle body and lands on the road surface. It is a device that simplifies the electric lift of this complicated equipment, does not protrude from the vehicle body, has no slope, the floor of the car lands on the road surface, and can easily carry in a wheelchair.
課題を解決するための手段Means for solving the problem
ディファレンシャルギアが後部まで伸びない前輪駆動車を用いれば、左右の後輪を繋ぐパーツは不要となる。シャーシー以外のパーツの装着を移動する事で、両輪の間に空間も出来る。移動不可能なのは車の脊髄であるシャーシーであるが、このシャーシーの基本構造は、二列の従鉄骨と数本の横鉄骨からなる梯子型である。この梯子型の最後部の梯子段を取り払う。後部荷台に乗せる車椅子の幅は略６０ｃｍで、縦列の鉄骨の間はすり抜けるが、後部梯子段はすり抜けられないから、この段を取り払い、車椅子の面積分の床も切り取る。こうして車椅子が納まるスペースを確保し、この取り払った部分に、可動式の床を新たに設ける。その動力として上下だけに作動する電動モーター駆動油圧式で可動床とシャーシーを接続すれば、自在に路面まで降下し、平行と成って車椅子の搬入も手軽となる。尚、取り払った後部梯子段でシャーシーは弱体構造となるが、その補強は幾らでもある。さらに、バンパーも切り取ることは言うまでもなく、後部ドアーに取り付ける事も出来る。If a front-wheel drive vehicle whose differential gear does not extend to the rear is used, parts for connecting the left and right rear wheels are not required. By moving the mounting of parts other than the chassis, a space can be created between both wheels. What is immovable is the chassis, which is the spinal cord of the car. The basic structure of this chassis is a ladder type consisting of two rows of secondary steel frames and several horizontal steel frames. Remove the last ladder step of this ladder type. The width of the wheelchair on the rear luggage carrier is approximately 60 cm, and it passes through between the columns of steel frames, but the rear ladder step cannot be passed through. Therefore, this step is removed and the floor for the wheelchair area is cut off. In this way, a space for the wheelchair is secured, and a movable floor is newly provided in the removed portion. If the movable floor and the chassis are connected by an electric motor drive hydraulic system that operates only up and down as the power, it will descend freely to the road surface, and it will be parallel, making it easy to carry in a wheelchair. In addition, the chassis becomes a weak structure at the removed rear ladder step, but there are many reinforcements. In addition, the bumper can be attached to the rear door, not to mention cut out.
考案の効果The effect of the invention
トラックのプラットホームが上下して積み下ろしするテールリフトは、１トン級の重量物も簡単に扱えて運送業界でも重宝されている。電動モーター駆動油圧式であるテールリフトが降昇する事で、路面と並行すれば、然程の腕力も体力も必要もなく、介抱者は勿論、車椅子の作動できる軽度の介護人なら、自身で自在に乗り降りも出来る。さらに、福祉機器で車内を占有しない。Tail lifts, which can be loaded and unloaded by truck platforms, can easily handle even one-ton heavy goods and are useful in the transportation industry. The electric motor-driven hydraulic lift lifts and lowers, so there is no need for any arm or physical strength if it is parallel to the road surface. You can get on and off freely. In addition, welfare equipment does not occupy the interior of the vehicle.
