Lockbox systems for securing items in a vehicle. In one embodiment, a hollow rectangular body has an open side which may be closed by a door. One or more L shaped locking members are disposed on the rear of the door adjacent a first longitudinal side. As the door is closed, the members are positioned to reside in locking recesses in a wall of the body, abuttably locking the door at the hinged side. Near a second side of the door, a locking mechanism is disposed that can be actuated to move a locking bolt into a bolt recess to secure the door in the body opening. The rear side surfaces of the door may be beveled to pair against a ridge disposed inside the opening to deter attempts to pry the door open.

A locking apparatus for use in securing a pivotably mounted lid of a refuse container includes a clamp assembly rotatably mounted to the container's handle and having a fork member, an arm coupled to the clamp assembly and in contact with the lid, a ring slidably mounted to the arm and clamp assembly, a mounting bracket coupled to the container's handle and connected to the clamp assembly by at least one spring, the mounting bracket having a base plate and an upper portion of the mounting bracket having at least one bumper, a rod fastener coupled to the base plate and fork member, and a rod member slidably mounted to the rod fastener. The rod member adjusts to permit the clamp assembly and arm to rotate such that the bumper releases the ring from the arm and clamp assembly upon contact, thereby enabling the container's lid to open.

A cooling appliance including a locking mechanism configured to fix the door to the main body at a different position from the latch mechanism, in a state where the door fixed to the main body by the latch mechanism closes the cooking chamber, wherein the locking mechanism provided in the door may include a shaft moved to a fixing position, at which the shaft is coupled to the hinge member, or a releasing position, at which the shaft is released from the coupling state, by a repeated pressing manipulation.

A hinge locking device for a door includes a mounting plate defining an upper plate end and a lower plate end, a plate slot extending into the mounting plate at the lower plate end, the plate slot configured to receive a hinge plate of a door hinge assembly therethrough; a reinforcement gusset affixed to the mounting plate and defining a gusset recess aligned with the plate slot; and a barrel channel defined between the gusset recess and the mounting plate, the plate slot allowing lateral access to the barrel channel, the barrel channel configured to receive a hinge barrel of the door hinge assembly.

A safety gate includes a first column, disposed on a first side of an elevator shaft, a second column, disposed on a second side of the elevator shaft, a first gate panel, and a second gate panel. The first gate panel is coupled to the first column via a first locking hinge. The second gate panel is coupled to the second column via a second locking hinge.
