Removable door-locking device

Claim 2

For use with a door that is pivotably mounted in a frame, the door having a latch movable into a cooperating recess in the frame, a removable door-locking device comprising: a pair of adjacent wedges each having an abutment surface and a locking surface that lies at an acute angle to said abutment surface, each of said wedges having a main slot bounded on one side by said locking surface and a secondary slot extending from said main slot toward said abutment surface to permit said connecting means to move toward said abutment surface; a hook having a body portion normal to said abutment surfaces that is at least partially disposed between said wedges and capable of projecting from between said wedges past said abutment surfaces, and at least one end portion extending from said body portion at an angle thereto for insertion in said recess; and connecting means attached to said hook for slidably engaging said locking surfaces; whereby one of said abutment surface can engage the door while the other of said abutment surfaces engages the frame to hold the door in a closed position.

Claim 3

The device of claim 1, wherein said connecting means comprises a pin which extends from said hook, and into said slots.

Claim 4

The device of claim 2, wherein said connecting means further includes retaining means for preventing said pin from being removed from said slots.

Claim 5

For use with a door, and a frame on which the door is hinged that includes a recess for engagement by a latch carried by the door, a removable door locking device comprising: a pair of adjacent wedges each having an abutment surface and having a slot one side of which is formed by a locking surface that lies at an acute angle to the abutment surface, said locking surface defining a series of closely spaced detents, each wedge including a secondary slot that extends from said first-mentioned slot toward said abutment surface to permit movement of said pin toward said abutment surfaces; a hook formed by an elongated metal strip having a flat main body and two end portions bent in opposite directions to form right angles with said main body, said main body being at least partially disposed between said wedges and movable with respect to said wedges; a pin extending from said hook into said slots to engage selected detents on said locking surface; and retaining means for preventing removal of said pin from said slots; whereby one of said end portions can be inserted in the recess of the frame and the positions of said pin relative to said locking surfaces can be adjusted so that the abutment surface of one of said wedges engages the door and the abutment surface of said other wedge engages the frame to hold the door in a closed position.

Claim 6

For use with a door, and a frame on which the door is hinged that includes a recess for engagement by a latch carried by the door, a removable door locking device comprising: a pair of adjacent wedges each having an abutment surface and having a slot one side of which is formed by a locking surface that lies at an acute angle to the abutment surface, said locking surface defining a series of closely spaced detents, each wedge including a secondary slot that extends from said first-mentioned slot toward said abutment surface to permit movement of said pin toward said abutment surfaces; a hook formed by an elongated metal strip having a flat main body and two end portions bent in opposite directions to form right angles with said main body, said main body being at least partially disposed between said wedges and movable with respect to said wedges; a pin extending from said hook into said slots to engage selected detents on said locking surface; and retaining means for preventing removal of said pin from said slots; whereby one of said end portions can be inserted in the recess of the frame and the positions of said pin relative to said locking surfaces can be adjusted so that the abutment surface of one of said wedges engages the door and the abutment surface of said other wedge engages the frame to hold the door in a closed position.
