The outside metal fitting M<SB>11</SB>and the elastic seat plate K are arranged on the outside and inside of the blindfold board P, respectively, and the bolts 1 of the outside metal fitting M<SB>11</SB>are inserted into the bolt holes 41, 6 of the blindfold board P and the elastic seat plate K, respectively, so that the outside metal fitting M<SB>11</SB>may be tentatively held to the blindfold board P. On the inside of the fence F, a connecting plate part 4 of an inside metal fitting M<SB>12</SB>having a clamp plate part 3 arranged on the outside of a vertical bar C of the fence F, and the seat plate 2 of the outside metal fitting M<SB>11</SB>are connected to each other by the bolts 1 integrated with the seat plate 2, and by nuts 7, so that the blindfold board P may be mounted on the fence F only by the work from the inside of the fence F. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
