Heating radiator anchor bolt - has tubular expanding member without steps forming abutment for head at free end

摘要

The anchor bolt secures a heating radiator in position, having a tubular clamping member inserted in a wall drilling and slotted at the inner end, which is expanding by a screwed bolt. A holding head fits in the annular space between the bolt and the outer end of the member to prevent radial movement of the bolt, being gripped when the latter is tightened between its head and an annular abutment on the member. The portion of the head protruding from the member has a groove at right angles to the bolt, in which the radiator is supported. - The tubular member (22) has no stepped portions, and the abutment for the head (24) is formed by its free end face. The head has a boss (23) turning in the forward end of the annular space, while its outer part bears against the member end and is eccentric to the boss, protruding radially beyond the member in one direction only.(1,2/2)
