PROBLEM TO BE SOLVED: To develop a movement structure for cats in which cats habits are used, and even a human life space can be harmonized, while solving problems of exercise shortage of an indoor domestic cat and environmental construction capable of promoting health.SOLUTION: A movement structure 1 for cats is made in combination of multiple kinds of stylized members. The movement structure 1 for cats comprises at least one kind of hollow member becoming a framework for development and extension in the vertical and horizontal directions, the members that are frame members 2 provided with connections capable of being fit to each member at both ends, connecting members 3 for enabling extension to the horizontal direction by loosely fitting or fitting to the frame members 2, connecting fitting auxiliary members 4 for stabilizing the fitting places in the frame members 2 and the connecting members 3, and plane-shaped step members 5 installed by loosely fitting to the frame members 2 and serving as the footing of the cats.SELECTED DRAWING: Figure 20COPYRIGHT: (C)2018,JPO&INPIT【課題】ネコの習性を利用し,室内飼い猫の運動不足の解消と健康増進しうる環境の構築を課題としながら,かつ,人間の生活空間にも調和しうるネコ用運動構造体等の開発を課題とする。【解決手段】ネコ用運動構造体1は,定型化された複数種の部材を組み合わせて作製される。当該ネコ用運動構造体1は,鉛直方向ならびに水平方向に展開・伸長するための骨組みとなる少なくとも1種類の中空状の部材であって,両端部に各部材と嵌合可能な接続部が設けられたフレーム部材2と,フレーム部材2に遊嵌ないし嵌合することにより,水平方向への伸長を可能にするための連結用部材3と,フレーム部材2ならびに連結用部材3において,嵌合箇所を安定化させるための連結嵌合補助部材4と,フレーム部材2に遊嵌することにより設置され,平面形状でネコの足場となるステップ部材5と,を含んでいる。【選択図】図20
