Abstract

A door securing device that can be secured and removed from a door easily and quickly and can be collapsed into a small unit for transport if desired. The door securing device comprises a base member, a brace member, and a projecting lip coupled to the door by way of an elastic member coupled to a door handle. The base member includes a projecting lip for engagement with the bottom of the door. A door handle hook being pivotally coupled to a telescoping shaft containing the elastic member therein, the hook being coupled to the door handle and the telescoping shaft extended under elastic bias such that the lip is positioned against the bottom of the door. The elastic bias securely holds the lip against the bottom of the door, and thus the door securing device to the door. The hook and shaft are pivotally coupled such that the shaft is positioned substantially parallel with the door. The door securing device remains on the door when in the locked or unlocked position. The brace member is pivotally mounted to the base member and is positional from an up position to allow free movement of the door and a down position to restrict movement of the door. In the down position, the brace member contacts the floor with a resilient foot that provides a gripping action to the brace member to prevent sliding on the floor. When the brace member is engaged with the floor, an opening force on the door will cause the brace member to pivot about the base member causing a force acting on the brace member about the foot which grips the floor and applies a force to the base member to cause forceful upward pressure on the bottom of the door. This upward pressure causes the door to be jammed against the door hinges and/or the doorframe preventing the opening of the door.

Dependent claims

A door securing device that resists the opening of an inwardly-swinging door, the door having an inner surface, an outer surface, a bottom surface, and a door handle having a stem, the stem coupled to the inner surface, the door being disposed above the floor, the door securing device comprising:

a head member having an engagement hook adapted to hang from the stem of the door handle;
a telescoping shaft being extendable and contractible in length, the shaft having a spring-bias that provides a restoring force when the telescoping shaft is in an extended position, the shaft having a shaft first end and a shaft second end, the head member coupled to the shaft first end;
a base member having a top, a bottom, a front and a back, the shaft second end coupled to the top, the bottom having a lip extending rearward a designated distance and in abutment with the door bottom directly below the door handle and the back in abutment with the door inner surface, the base member coupled to the door by the spring bias acting on the head member and the base member;
and
a brace member comprising an elongated leg having a pivot end and a foot end, the pivot end pivotally coupled with the front of the base member, and the foot end adapted for gripping engagement with the floor, the leg pivotally positional between an up position wherein the foot end does not engage the floor and a down position wherein the foot end engages the floor.

A door securing device that resists the opening of a swing-in door, the door having an inner surface, an outer surface, a bottom surface, a hinged edge, and an outer edge opposite the hinged edge, the door being disposed above the floor, the door securing device comprising:

a channel structure having a first and second side in parallel relationship and a third side between and perpendicular to the first and second sides defining a channel, the channel slideably received on a portion of the door proximal the door bottom surface wherein the first and second parallel sides and perpendicular side are adjacent the inner and outer surfaces and outer edge, respectively, the first parallel side further comprising a threaded aperture;
a screw clamp having a threaded shaft, a knob and a push plate, the threaded shaft threadably advanced in the threaded aperture, the threaded shaft having a first end and a second end, the first end coupled to the knob and the second end coupled to the push plate, the push plate positioned between the door inner surface and the first parallel side, the clamp adapted to advance the pressure plate against the door inner surface as the knob is turned to removably secure the channel structure to the door;
a base member having a bottom, a front and a back, the back coupled to the first parallel side, the bottom having a lip extending rearward a designated distance and in abutment with the door bottom;
and
a brace member comprising an elongated leg having a pivot end and a foot end, the pivot end pivotally coupled with the base member, the foot end adapted for gripping engagement with the floor, the leg pivotally positional between an up position wherein the foot end does not engage the floor and a down position wherein the foot end engages the floor.

2 more elements

A securement device comprising:

a door defining a door opening in a door frame consisting of side and top segments and said door having opposing side edges and opposing bottom and top edges, said door mounted for pivotal opening at one side edge to a side segment of said frame and with said bottom edge of the door slidably moving along and in close proximity to a floor underlying the door;
a bracket secured to the door adjacent the bottom edge and proximal to the opposite side edge;
an elongate brace member pivotally mounted to the bracket at one end and having a foot portion at the other end, said brace member pivotal in a vertical plane between a raised position adjacent the door and a lowered position with the foot portion engaging the floor, said elongate brace member and foot portion angularly configured when in the lowered position whereby the foot portion engages the floor and pivotal movement of the door toward the foot portion results in lifting of the door and binding of the door within said door frame to prevent opening of the door.
