ABSTRACT:
A security bar for preventing uninvited opening of a building door comprising an elongated tubular pole which may be formed from telescoping segments and which has a footpad secured to the lower end thereof and a specially designed head member affixed to the opposite end, the head member having an angled face such that when the plane of that face abuts the planar surface of a door, the pole will be at a predetermined angle to the horizontal. The head also includes an arcuate recess formed inwardly from its top surface for cooperating with a door knob of the lockset used with the door. When the head member straddles the door knob with the angled face thereof resting against the door surface, the pole extends at an angle to the floor acting as a brace to prevent the door from being opened against the device.
