PROBLEM TO BE SOLVED: To provide a roof member at a low cost by applying an existing member.SOLUTION: A pet circle 1A is constituted by connecting by a linear part fastener 3, mutually adjacent longitudinal direction ends 21 of a plurality of sheets of fence members 2 including a frame body 20 comprising right and left vertical rods 22 and upper and lower horizontal rods 23 for connecting both upper and lower ends of the respective vertical rods 22, in first and second linear parts 11a and 11b of a circle body 10A, and also connecting by a corner part fastener 4 in a corner part 12. An opening 19A opening to the upside of the circle body 10A is blocked by laying roof members 7 on top faces of a fan-shaped connection member 41 and a long material 32 in a state of combining two sheets of the roof members 7 comprising a frame body 70 same as the frame body 20 of each of the fence members 2. Each of the roof members 7 is fastened through a detachable fastener 8 to the circle body, and the roof members 7 are supported through a hinge 89 so as to be opened and closed to the other roof member 7 when fixation of one of the roof members 7 by the fastener 8 is released.COPYRIGHT: (C)2014,JPO&INPIT【課題】既存の部材を流用して屋根部材を安価に提供する。【解決手段】左右の縦杆22と各縦杆22の上下両端を連結する上下の横杆23とからなる枠体20を備えた複数枚の柵部材2の互いに隣接し合う左右方向端21同士をサークル本体10Aの第1及び第2直線部11a,11bにおいて直線部用固定具3により連結すると共に角部12において角部用固定具4により連結してペット用サークル1Aを構成する。各柵部材2の枠体20と同一の枠体70よりなる屋根部材7を2枚組み合わせた状態で、扇状連結部材41及び長尺材32の上面に載置し、サークル本体10Aの上方へ開口する開口部19Aを閉塞する。各屋根部材7を、サークル本体に対し脱着自在な固定具8を介して固定するとともに、屋根部材7同士を、そのうちの一方の屋根部材7の固定具8による固定が解除されたときに他方の屋根部材7に対し開閉されるようにヒンジ89を介して支持している。【選択図】図2
