Claims

[Scope of utility model registration request]

(1) Make insertion holes at one or two arbitrary positions on the bottom surface of the cylindrical rail through which the bolt head passes, provide a slit of the diameter of the bolt continuous from the insertion hole, and provide a slit at the end of the slit. reaches a predetermined position to set a pair of bolts maintained at a constant interval in the longitudinal direction of the lower surface of the rail, and on the other hand, a rail seat with a concave curved surface that is open at the top and comes into contact with the lower surface of the rail is provided at the top of the support. A recess is provided at a point that communicates with the slit end at the predetermined position, a bolt through hole is made in the bottom of the recess, a pair of bolt heads are inserted through the insertion hole in the lower surface of the rail, and the bolt is inserted at the end of the slit on the lower surface of the rail. A column-to-rail coupling device in which a bolt is temporarily fastened with a nut, protrudes from the underside of the rail, is placed on the column by aligning it with a through hole in the column seat, and is tightened with a nut on the bottom surface of the column.

(2) The support and rail coupling device according to claim (1) of the utility model registration claim, wherein the end position of the slit provided on the lower surface of the rail is a predetermined position that maintains an appropriate interval on a straight line in the direction of the pitcher's force. .

(3) The support and rail coupling device according to claim (2), wherein the slits provided on the lower surface of the rail are symmetrical to each other.
