Disclosed is a Sleeve Stop Lock that is a portable, removable, non-damaging door lock that can be used to secure almost any inward swinging door from the outside. The apparatus consists of three components: a sleeve, a stop, and a lock. The “sleeve” component fits around the edge of a door. It is installed while a door is open. With the door closed, the “stop” makes contact with the door frame once attached to the sleeve thus preventing the door from swinging inward. The “lock” mechanism then securely binds all of the components together. The combination of these three elements (sleeve, stop and lock) prevent potential intruders (including housekeeping) from entering and invading the privacy of an unoccupied room.

The present invention is directed to a door latching device that can be deployed in emergency situations to lock down a classroom, business, church, home or any other building. The device comprises a backing plate, a hinge body, a jamb hook and a hinge shaft that can pivot, thereby moving the jamb hook from a stored position to a latched position and vice versa. When the device is in a latched position, the device prevents a door from opening. The device can be moved from the stored position to a latched position, and conversely from the latched position to the stored position, with the use of only one hand and without the use of a specialized key.

A device for securing a door including a rotatable handle affixed to the door, a rotatable member affixed to the door, a catch, and a protrusion from the rotatable handle that is configured to lift the member when the member is engaged with the catch and the rotatable handle is rotated. A device for securing a door including a member configured to be rotatably attached to the door, a catch configured to be attached to a wall adjacent to the door and to receive the member, and a protrusion configured to be attached to a handle on the door and to lift the member when the member is in a closed position and the handle is rotated. A method for installing a device for securing a door with a handle, the method including affixing a member to the door so that the member can rotate, affixing a catch to a wall adjacent the door, the catch configured to receive the member, and affixing a protrusion to the handle, the protrusion configured to lift the member when the member is engaged with the catch and the handle is rotated.

A door lock assembly for a door hinged to a door frame, having primarily a two-part lock assembly, including a linear pin or bolt having a first pin end and a second pin end, the second pin end formed with a handle attached and a magnet positioned therearound the second pin end and proximate a junction between the handle and the second pin end and a mounting plate having a first plate end and a second plate end, the plate ends having a one or more mounting holes, the mounting plate having a base or humped body positioned between first plate end and a second plate end, the humped body having a locking aperture positioned crosswise there through the humped body to receive first pin end.

Embodiments of the present application relate to the technical field of daily necessities, and in particular to a lock and a suitcase. The lock comprises: a lock main body, which is provided with an accommodating cavity, an opening, and a first through hole, and the opening and the first through hole both being in communication with the accommodating cavity; an elastic member, one end of which is fixed on the bottom of the accommodating cavity opposite the opening; and a clamping button, which comprises a button main body provided with a groove and a clamping boss obtained by extending from the button main body towards the groove, wherein the button main body is inserted into the accommodating cavity from the opening, the button main body is movable relative to the lock main body, the button main body abuts against the other end of the elastic member, and the clamping boss corresponds to the first through hole. By means of the lock, when a zipper piece on the suitcase presses the clamping button of the lock, a hole in the zipper piece is clamped into the clamping boss, and thus, the zipper piece on the suitcase can be locked.

A locking device intended to prevent opening of a door/doors includes a body, which is capable of being coupled immovably to a door handle and prevents opening of a door/doors. The body is provided with a coupling arrangement adjustable with adjustment elements for locking the handle against an external surface of the door by being propped immovably on a vertical frame member of the door or on a handle of the adjacent door.

A method for retrofitting a roll door lock that enables both manual and remote wireless locking and unlocking of a roll door. More specifically, the retrofitted lock comprises an interior plate with a cylinder lock aperture, a motorhead gear coupled to a motor and rotationally secured within the housing, and a controller functionally coupled to the motor, wherein the controller may be commanded to operate the motor to lock the roll door lock by causing a blocking coupler edge to reduce the diameter of a ball-pin aperture, and unlock the roll door lock by withdrawing the blocking coupler edge.

An inner lock of a door of a container is provided, in which the door of the container includes: a plurality of locking rods installed on an outer side of the door; a handle formed on the locking rods; a retainer which is coupled to the door and on which the handle is seated; and a handle hatch which is rotatably coupled to an upper side of the retainer and binds or releases the handle, and the inner lock includes a rotation shaft passed through the door and extended to an inner side and an outer side of the container; a plate coupled to the rotation shaft extended to the inner side; a lifting member rotatably coupled to the plate; and a locking bar coupled to a lower side of the lifting member to lock or unlock the door by being fixed to or separated from a lower frame, in which the handle hatch is coupled to the rotation shaft extended to the outer side such that the locking bar is manipulated by rotating the rotation shaft from the outer side of the door.

A security reinforcement system for a door assembly having a door frame with first and second spaced-apart vertical structural supports and a door hinged thereto has first- and second-channel base plates respectively mountable to the first and second vertical structural support. Pivotally attached to the first and second base plates, respectively, are first and second opposed pluralities of security arms which rotate from a retracted position to an extended position in which security arms of the opposed pluralities extend toward each other across a portion of the door, reinforcing the door when first and second actuator arms operatively coupled to the first and second pluralities, respectively, are rotated from a vertical position to a horizontal position and are releasably coupled together by a sleeve.

The present invention relates to an installation structure of an auxiliary locking device for a hinged door, and by operating a rotation lever installed on a door frame separately from a generally used security main locking device, the rotating opening side of the hinged door is vertically attached to the door frame in close contact with the door frame at a number of points in the longitudinal direction, and in order to make it easier to fix and maintain such a tight state. More particularly, the present invention is directed to providing new installation structure of the auxiliary locking device of the hinged door capable of preventing the mutual interference of the driving plate and locking piston, even if the longitudinal installation range of the driving plate is overlapped with the operating range of the locking piston constituting the second locking tool.
