Methods and apparatus for using a look on a door lever handle are disclosed. The lock includes a base configured to mount the lock to a door having a lever handle and a lever handle guard pivotally attached to the base, the lever handle guard being pivotable between a locking position and a non-locking position. The lever handle guard is securable in the non-locking position. The lever handle guard includes first and second guard portions arranged to prevent rotation of the lever handle when the lever handle guard is in the locking position. When the lever handle guard is secured in the non-locking position, the first and second guard portions are arranged to permit rotation of the lever handle without contacting the first and second guard portions.

A security device for a trailer door which has a rotatable post for a locking door and a bar member secured to the post, the security device comprising a plate member for securement to a substrate, a cover hingedly connected to the plate member and movable between an open and closed position, a locking device mounted at one end of the cover, the locking device having a housing, a plunger mounted within the housing, the plunger being movable between an extended position and a retracted position, the plunger being spring biased to the extended position, and a deflector extending upwardly from the plate member, the deflector having an aperture formed therein, the plate member being located such that the plunger enters the aperture when the cover is in a closed position.

For a hanging flexible flap having a top and bottom end for reminding a driver, upon exiting, of the vehicle's occupancy for a vehicle having a driver-side door handle including a lever operable for opening the door, deployment, proceeding from a pre-deployment state in which the flap is in a folded-up configuration such that the bottom end is releasably attached to a second interior-side location vertically above a first interior-side location to which the flap is attached and both locations are vertically above the lever and jointly high enough that the flap does not cover the lever along at least most of the lever's length, includes undoing the releasable attachment; and unfolding the flap, or letting it fall, to hang down covering the lever along at least most of the lever's length. Alternatively, pre-deployment may be in a spring-biased rolled-up configuration, with the flap unrollable down to cover the lever.

A hidden-lock door panel for use in a container includes a door panel body, a covering lid, a first lock, and a second lock. The door panel body includes a hidden space. The covering lid is disposed corresponding to the hidden space and slidably connected to the door panel body. The first lock and the second lock are both disposed in the hidden space. The first lock is an electronic lock and is used to control whether the covering lid can be released to slide. The second lock is used to control the door panel body to be unlocked or locked with respect to the container. Accordingly, unknowing persons are prevented from opening or breaking the door lock.

Disclosed is a closure for a door of a shipping container. The closure includes a housing, an outside handle pivotally mounted relative to the housing, an inside handle pivotally mounted relative to the housing, and a catch connected to the inside handle. The closure is configured so that movement of the inside handle between a first position and a second position causes corresponding movement of the catch. A locking mechanism can releasably fix the inside handle relative to the outside handle, such that when in a locked position rotation of the outside handle causes corresponding rotation of the inside handle and when in an unlocked position the inside handle can be rotated independently of the outside handle.

A restrictor having flexible adjustable arms so that it may fit various opening sizes and shapes. The overall shape can be crisscross or spider web design. Attachments such as clips, clamps or other fastening devices can be provided to make attachment to the perimeter of the opening easy.

An alarm for a door is operable to generate an alarm signal when a rotary grip member of the door is rotated to a particular position, such as an unlocked position. The alarm comprises a housing having a strap retainer configured to receive and retain a strap to hold the housing to the rotary grip member. The alarm comprises a tilt switch for switching when the housing is tilted. Control circuitry is interconnected to the tilt switch and to an annunciator and is operable to activate the annunciator dependent on a state of the tilt switch.

A locking doorknob shroud, configured to be placed over a doorknob, padlock, or similar closing mechanism. The shroud is equipped with two halves which interlock together and seal firmly with a latch. A keyhole, present at a junction of the two halves within the latch, is configured to accept a key, which when turns, unlocks the latch. Alternately, or in addition, a padlock may be used to further secure the latch. A spring assembly disposed in communication with at least one hinge enables the two halves to open about the at least one hinge, providing access to the doorknob when permitted.
