PROBLEM TO BE SOLVED: To arbitrarily adjust a load applied to an animal during walking and to train an animal to walk without taking a sinuous course.SOLUTION: The body-weight supported walking machine 1 includes a movable gate-shaped frame 2 provided with wheels 6, a harness 8 for lifting and supporting an animal, a support bar 9 for lifting and supporting the harness 8 by a connection belt 13, and a wire 10 for liftably and lowerably hanging the support bar 9 through the gate-shaped frame 2. The wire 10 makes the support bar 9 liftable and lowerable by lifting and lowering a winding movable pulley 22. An operation handle 26 is operated to turn a screw shaft on its axis, a rack member 32 attached to a bracket of the movable pulley 22 is screwed to a trapezoidal screw thread of the screw shaft, and the harness 8 holding a dog is lifted and lowered to control a body-weight support amount. The body-weight support amount is measured by a body-weight measuring instrument 23 connected to the wire 10 and is accurately set. A traverse correction bar 34 is mounted on both supports 4 and connected to the harness 8 by a connection band to prevent transverse slippage and body twist of dog.COPYRIGHT: (C)2013,JPO&INPIT【課題】歩行時に動物にかかる荷重を任意に調整し、動物を迷走させずに歩行訓練できる。【解決手段】動物用免荷歩行訓練器1は、車輪6を備えて移動可能な門形フレーム2と、動物を吊り上げ支持するハーネス8と、ハーネス8を連結ベルト13によって吊り上げ支持する支持バー9と、支持バー9を門形フレーム2を通して昇降可能に吊り下げるワイヤー10とを備えた。ワイヤー10は巻回する移動プーリ22を昇降させることで支持バー9を昇降可能とした。操作ハンドル26を操作してねじ軸を自転させ、移動プーリ22のブラケットに設けたラック部材22とねじ軸の台形ネジを螺合させて犬を保持したハーネス8を昇降させて免荷量を調整する。免荷量はワイヤー10に接続した免荷量測定器23で測定し、正確に設定する。両支柱4に横移動矯正バー34を取り付け、連結バンドによってハーネス8に連結することで、犬の横ズレや身体の捻れを防止できる。【選択図】図1
