A multifunction lock unit is disclosed. The unit is a single, contained unit that includes a base box near an overhead door and a deadbolt in the base box that protrudes into a hole in the overhead door to lock the overhead door. The deadbolt is extendable into the hole and retractable out of the hole. The unit also includes an actuator in the base box coupled to the deadbolt and configured to extend and retract the deadbolt. There is a wireless communication module that can receive a signal from a control unit to extend or retract the deadbolt via the actuator, and send a signal to the motor unit to raise or lower the overhead door. The unit also has a light on the base box for displaying at least two colors of light to show a status of the unit.

A locking mechanism for use with a door structure having a corrugated surface includes a main body having a corrugated surface. The locking mechanism is configured to be adjustable between an unlocked position where the corrugated surface of the main body is not nested relative to the corrugated surface of the door structure and a locked position where the corrugated surface of the main body is nested relative to the corrugated surface of the door structure. The corrugated surface of the main body includes a plurality of engagement surfaces. Each of the engagement surfaces is configured to resist movement and/or deformation of the door structure with respect to a direction of movement of the door structure associated with the door structure being moved from a closed position towards an open position.

A roll up door assembly is mountable in two tracks laterally spaced from one another, each track including a catch, the roll up door assembly including a door sized to be mountable and slidable along the tracks between a closed position and an opened position, the door being a roll up door including a plurality of slats extending between the tracks, one of the slats being a locking slat having an outer surface and an inner surface and defining a passage therethrough between the outer surface and the inner surface. A housing is attached to the outer surface of the locking slat, the housing defining an opening therethrough aligned with the passage. A key cylinder extends through the passage and the opening. A two-point latching assembly has two latches for selectively engaging the catches and is rotatably driven by a rear portion of the key cylinder adjacent the inner surface of the locking slat. A fixing member threadedly engages an outer surface of the key cylinder to secure the key cylinder to the housing, the fixing member being annular and being configured with the housing and the locking slat so that the fixing member has an axial length at least as long as a distance between an inner surface of the housing and the outer surface of the locking slat when the fixing member is positioned to secure the key cylinder to the housing.

A door operating system includes: a handle having: loop shaped gripping portion; an attaching portion defining a slot; structure enclosing the slot, the structure defining fastener holes, wherein the slot is defined by the attaching portion and the structure enclosing the slot; and a door operating lever located in the slot. A method of making a door operating system includes: forming a handle having loop shaped gripping portion and an attaching portion; forming a slot in an attaching portion; enclosing the slot with a structure, the structure defining fastener holes, defining the slot with the attaching portion and the structure enclosing the slot; locating a door operating lever in the slot; and attaching the handle to the operating lever with fasteners located in the fastener holes.

A door and locking system for a rear opening of a long bed trailer, the rear opening having a top edge, a bottom edge and first and second side edges, the door and locking system has a canvas door configured for mounting adjacent to the rear opening of the long bed trailer. The canvas door can move between a closed position in which the canvas door moves to close the rear opening and an open position in which the canvas door moves to open the rear opening. A locking system secured to the edges of the rear opening can move between a locked position, in which the locking system is in locking engagement with the canvas door in the closed position to secure the canvas door against the edges of the rear opening to close the opening for retaining fluidizable product in the long bed trailer and an unlocked position, in which the locking system is free from locking engagement with the canvas door to allow the canvas door to move into the open position.

The invention concerns a lock unit, comprising a lock assembly having a locking element and a drive receiving portion operatively associated with the locking element and a drive unit connected to the lock assembly, the drive unit having a motor and being configured to move the locking element of the lock assembly from a locked position to an unlocked position, the drive unit including a driving element that interfaces with the drive receiving portion of the lock assembly to move the locking element from the locked position to the unlocked position, wherein the drive unit is selectively separable from the lock assembly. The invention facilitates fitment of the lock assembly in position, provides a more compact and secure solution, and assists in regard to maintenance.

An anti-burglar bar (1) for rolling shutters (2) or rolling gates, which are defined by a plurality of horizontal slats (3) associated with a winding roller and are slidable in a first and a second vertical guides (4,5) opposite to one another, comprises electromechanical control means (7) of a first and a second blocking elements (8) and (9), arranged slidingly in a body (11), which engage respectively in a first and a second retention blocks (10) associated with said first and second guides respectively, a first and a second feelers (12) being provided which engage respectively with a first and a second position sensors (13) for transmitting an electric signal, said electric signal activating said electromechanical control means (7) only when said first and second feelers (12) are simultaneously aligned with said first and second position sensors (13) respectively.

An overhead door interlock device provides an electrical signal indication of the locked or unlocked status of an overhead door, and interfaces with control circuitry of the door's opener to allow or disallow operation of the door based on the locked or unlocked status. In one embodiment, a lever is pivotably attached to the doors track, with the lever engaging with a switch mechanism to indicate the locked or unlocked status of the door. A spring mechanism automatically returns the lever to an unlocked position when the door's lock bar is retracted, with the lever mechanically inhibiting locking of the door until the lever is moved by a user.

A lock for overhead roll doors and particularly a retrofit lock that enables both manual and remote wireless locking and unlocking of a roll door. More specifically, a roll door lock having 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.
