    摘要: This security bar for positioning between a door and the floor has telescopic sections which permit the door to be opened a small distance, corresponding to the degree of telescoping which is permitted, so as to permit a clear gap between the door and its frame, if desired. The sections telescope by virtue of a bolt positioned through holes in one of the sections and a slot in the other section, the length of the slot determining the maximum possible telescoping. A pin can be positioned through additional holes in the first section and through the slot, to restrict the degree of telescoping which is permitted, from the maximum telescoping down to essentially no telescoping at all. The overall length of the bar preferably is adjustable as well.
