PROBLEM TO BE SOLVED: To obtain a fixing device which can be stably installed by providing a lock for locking a cylinder at the front end a cross bar at the rear part respectively to constitute a connecting base sheet and connecting legs obliquely supporting the standing signboard and support legs and fixing them. SOLUTION: A connecting base sheet 1 is constituted of a sheet plate made of a metallic plate having a specified width, a cylinder 3, and a lock 4. A level difference bent at the front end is formed in the sheet plate. The cylinder 3 is fitted to the front end, and supported in a support piece through a shaft pin so as to be turnable. Further, a thum screw for fixing the leg is fitted. The key can be welded or the sheet itself 2 can be formed in a bent shape. Two connecting base sheets 1 are used in pairs. The legs 9 of the signboard 8 are fitted in the cylinder 3 and lock 4 is engaged with the cross bar 11 of the support legs 10 and fixed to a specified position. In the connecting base sheet 1, only the front end where the cylinder 3 is provided to come in contact with the ground and about half of the weight acts on the support legs 10. In this way, positional shift is eliminated and hence, the signboard can be stably installed and conveniently carried. |
