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.

A lock includes a pair of spaced apart parallel bolts connected by a plate extending between the bolts. A slot, formed in a hinged structure, such as a gate, extends from a free edge of the structure (an edge opposite a hinged edge) to an end point at a determined distance from the free edge. The plate is received in the slot. Each bolt is located on an opposite side of the hinged structure, when the plate is received in the slot. The slot defines a range of sliding motion of the plate and bolts.

A folding system has a bottom guide rail and a top guide rail. A first folding wing and a second folding wing are supported movably in the bottom guide rail and the top guide rail, respectively. The first folding wing has a vertically extending frame section. A lock fitting is arranged in the vertically extending frame section of the first folding wing and has a vertically slidably supported locking pin. A locking gear is connected to the locking pin and can move the locking pin into and out of one of the bottom and top guide rails. A reinforcement pin is arranged parallel to the locking pin in the vertically extending frame section of the first folding wing. The locking pin and the reinforcement pin are connected to each other such that the reinforcement pin is entrained parallel to the locking pin when the locking gear is actuated.

A safe and user-friendly door, especially for logistics containers, which preferably includes a quadrilateral frame, defining the perimeter for the door. A latch is provided movably to the frame so as to be manipulated between a locking state, in which at least a distal portion of the latch protrudes outside the perimeter, and a released state, in which the distal portion is flush with or inside the perimeter. The frame also preferably includes a diagonal guide, which is configured to guide the latch between the locking state and the released state by allowing deviation of the latch along a path diagonal to the quadrilateral shape of the frame.

A heavy duty lock case is mounted on a door and includes a latch coupled with a door frame for retaining the door in a closed position. An anti-theft latch can be operated to engage with the door frame. The latch cooperates with an anti-pick member to avoid the latch from being picked to disengage from the door frame when the door is in the closed position. When normally operated, an inner operating device or an outer operating device can be operated to disengage the latch from the door frame while disengaging the anti-theft latch from the door frame, permitting easy, convenient opening of the door.

The invention relates to a door lock having an oblique bolt. In the invention, stress of the parts of the oblique bolt susceptible to wear is reduced, wherein they remain functional longer. The oblique bolt consists of slanted surfaces on both sides such that the tip part is narrower at its tip than in the back part of the tip part. The tip part has recesses in its lower part and upper part, which extend from the tip to the back part. Both recesses are open at the end of the tip of the tip part and on the other slanted surface such that the recess of the upper part is open on the opposite slanted surface than the recess of the lower part. Both recesses have a turning piece.

The invention relates to an interactive security and locking system for residential doors, linked to the floor (A), the door (B) and the electrical panel (C) of the dwelling, comprising mechanical means of physical locking, in particular at least one bolt (3), electrical and electronic security means for its opening and closing and means for its management through an application (App) for Android and IOS systems on Smartphone and Smartwatch mobile devices, said App connecting with the closure of security directly (locally) via Bluetooth and GSM and remotely (external server) via Wi-Fi, GPRS and LAN, also implementing means of controlling access to the home, means for connecting auxiliary peripheral elements of security and a security device for opening the door, acting as a self-contained system or as a peripheral unit.

A novel proposition is herein presented for providing a safe and user-friendly door especially for logistics containers. The door includes a quadrilateral frame, which defining the perimeter for the door. A latch is provided movably to the frame so as to be manipulated between a locking state, in which at least a distal portion of the latch protrudes outside said perimeter, and a released state, in which the distal portion is flush with or inside said perimeter. The frame also includes a diagonal guide, which is configured to guide the latch between the locking state and the released state by allowing deviation of the latch along a path diagonal to the quadrilateral shape of the frame.
