The present invention discloses a mailbox apparatus including: a box for accommodating mail, wherein the box includes: two horizontal tracks, each of the tracks disposed at an inner upper part of an opposite sidewall of the box; and two pins, vertically disposed at the same level, each of the pins horizontally disposed at an entry side to one of the tracks; a door having side grooves in side facets of the door positionally corresponding to the pins, wherein the door adapted to have: an open state in which the door is horizontally disposed at an upper inner side of the box, thereby allowing insertion and extraction of the mail; and a closed state in which the door is vertically disposed. Preferably, the apparatus includes: a spring mechanism for applying force on the door while being inserted into the tracks, thereby retaining the door in position upon placing into the tracks.

An apparatus for physical correspondence recognition and processing in a postal system is described, comprising a housing comprising an opening for receiving physical correspondence, the physical correspondence including a readable element including textual information, and a secure enclosure for storing the physical correspondence, a visual processing and digitizing component, for processing the physical correspondence and the at least one readable element, dimension and weighing component for determining dimensions and weight of the physical correspondence, and a communication component coupled to the housing, for transmitting and receiving recognition and processing information related to the physical correspondence and readable element.

A double cylinder lock is disclosed which includes a first of the cylinders, called a service cylinder, being actuatable by a first key, the second of the cylinders, called a customer cylinder, being actuatable by a second key distinct from the first key, wherein the service cylinder may only be actuated once at most between two actuations of the customer cylinder the lock also including a module for detecting the actuation of the service cylinder.

Present embodiments relate to a revolving mailbox cluster and central package delivery system. More specifically, without limitation, present embodiments relate to a revolving mailbox cluster that includes: substantially circular layers stacked vertically, where a second layer sits atop a first layer, and wherein each substantially circular layers includes: vertically opposed bottom top plates, divider plates perpendicular to the bottom and top plates, and a center ring, where the bottom and top plates, dividers, and center ring define individual mailbox units, each of which has an opening disposed opposite the center ring; a first motor for moving the substantially circular layers vertically; and a second motor for rotating the substantially circular layers.

A lock can include attack-resistant and/or weather-resistant features. Attack-resistant features can include a sacrificial link between a locking mechanism and an external keyway covering an exterior face of the locking mechanism. The sacrificial link can break during a torque attack on the lock such that the full force of the torque attack is not applied to the locking mechanism. Weather-resistant features can include drain openings in one or more housing components external to the locking mechanism to facilitate drainage of liquid matter from the lock before the liquid matter reaches the locking mechanism.

A height-adjusting apparatus for a mobile foundation includes a rod with a threaded portion and a threaded plate, which is retained in an adjustable manner on the threaded portion and has a supporting surface. The height-adjusting apparatus also includes a tube, which has a cavity. The tube comprises at least one wall aperture on an outer side, as a result of which the rod projects into the cavity. Additionally, the height-adjusting apparatus is configured such that the rod can be rotated relative to the tube at least in part about an axis parallel to the longitudinal axis of the tube.
