Abstract
Apparatus for preventing the opening of a movable closure--such as a pivoted door--from either side thereof. First and second rods are pivotedly mounted together to be folded up for storage or transport, or to be disposed in end-to-end relationship when the apparatus is operative. A third rod slides with respect to the first and second rods and operatively engages the first and second rods to lock them together in end-to-end relationship. A fork for engaging the door knob is provided at one end of the rods, and an engaging member for securely engaging either a carpet or a smooth floor is provided at the other end of the rods. A chain having an enlarged loop at one end and an elongated pin at the other end cooperates with a tubular member formed on the rods to facilitate locking of a pivoted door from the jamb side thereof.
Claims13
Apparatus for preventing the opening of a movable closure comprising first and second elongated rods;
- means for pivotedly mounting said first and second rods for movement from a first position wherein the rods abut in substantially end-to-end relationship to a second position wherein the rods extend substantially parallel to each other;
- means for effecting adjustment of the effective length of at least one of said rods;
- means associated with said first rod for firmly abutting the movable closure;
- means associated with said second rod for engaging a stationary member adjacent the closure to prevent relative movement between the closure and the stationary member;
- and means for selectively locking said first and second rods in the first position thereof;
- said means for selectively locking said first and second rods in the first position thereof comprising a third elongated rod having a latching portion formed as a hook on one end thereof;
- means formed on one of said first and second rods for allowing guided linear movement of said third rod parallel to said one of said first and second rods;
- and latching means formed on the other of said first and second rods for cooperating with said latching portion of said third rod to maintain said third rod latched in a position wherein it extends across said first and second rods in operative engagement with each;
- said latching means comprising means defining an aperture in said other of said first and second rods for receipt of said hook therein.
Apparatus for preventing the opening of a movable closure comprising an elongated substantially rigid member having a first end thereof formed for abutting the closure;
- and means formed on a second end thereof, opposite said first end, for engaging a stationary member adjacent the closure to prevent relative movement between the closure and the stationary member;
- wherein the improvement comprises:
- said means for engaging the stationary member comprising a U-shaped engaging member having two legs, and having first and second substantially parallel faces, the faces having different textures each capable of engaging the stationary member without defacement or destruction of the stationary member;
- and for mounting said engaging member with respect to said elongated member so that the legs of said U-shaped engaging member are on opposite sides of said elongated member and so that said engaging member may pivot from a position wherein said first face engages the stationary member to a position wherein said second face engages the stationary member.
Apparatus for preventing the opening of a pivoted closure, for opening in one direction and abutting a jamb member for stopping movement in the other direction, said apparatus comprising:
- an elongated substantially rigid member;
- and
- means for operatively holding said elongated member between the pivoted closure and a stationary member adjacent either the jamb side or the opening side of the pivoted closure so that the pivoted closure may not move with respect to the stationary member whether said elongated member is disposed on the jamb side or the opening side of the pivoted closure.
