This present application relates to a movable tray for use with a mailbox, as well as a kit, to allow an individual to retrofit a mailbox to accommodate the moveable tray of the present invention. The moveable tray of the present invention has a low coefficient of friction and may use a system of rails and channels to allow easy pulling of the moveable tray from the mailbox to retrieve the contents of the mailbox.

A retractable arm device, system, and method with a locking mechanism for preventing items placed in a device or receptacle from getting stuck, damaged, or torn. The retractable arm includes an inner tube, a pawl, and an outer tube surrounding the inner tube. The inner tube slides within the outer tube and the pawl preventing the retractable arm from moving into an extended position under particular conditions. The retractable arm may be placed in a receptacle for items to prevent the door from being reopened before the door is fully closed.

An extendable and resilient mailbox is implemented in which the mailbox can revertibly extend outward to improve accessibility to the mailbox during heavy snowfall. The extendable mailbox is also configured with break-away action which enables the mailbox to laterally move and resiliently revert (or “break away”) to a base position. For example, when a snow plow inadvertently crashes into the extended mailbox, the mailbox will laterally move in the direction of the encounter to reduce the chances of or prevent the mailbox's destruction. Once the snow plow has passed or at least is no longer clashing with the mailbox, the extendable mailbox reverts back to its base position in which it is aligned with the mailbox post.

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.

To improve utilization efficiency of a delivery port and an unmanned aerial vehicle (UAV), a delivery port management system includes obtaining means for obtaining a delivery destination of a package that is transported by a UAV approaching a facility having a plurality of delivery ports and a plurality of delivery destinations, the delivery ports receiving packages, port selecting means for selecting a delivery port to which the UAV delivers the package among the plurality of delivery ports based on the delivery destination of the package after the UAV has departed for the facility, and guiding means for sending information for guiding the UAV to the selected delivery port.

A receiving module is disclosed herein. The receiving module can include a body and a door having a front shield and a rear shield coupled to the front shield at an angle. The body of the receiving module can include installation tabs that can include installation plates. The installation plates can be bent and placed against an installation surface to facilitate installation of the receiving module. The receiving module can be coupled to a container that includes a heating compartment and a cooling compartment to store delivered goods or packages in desirable temperature conditions. The receiving module can be modular and attached to different locations.

An extruded post used to support a sign, mailbox or set of rails, or in a stand-alone mode, with an interior light source to illuminate characters cut out of the wall of the post or rail for identification of a property or to transmit a message. The light source is inserted into the interior of the post or rail. A translucent sheet is placed within the wall of the post or rail and in front of the illumination source. A reflective backing, with a locking aspect, is inserted into the post or rail to reflect light from the light source thru the translucent sheet and thru the cut out characters. Power for the illumination is provided by a solar charged battery placed in a cap on top of the post. A processing unit is placed in line between the power source and the illumination to generate light patterns and effects.

A drone package drop adapter has a first chute section, a second chute section, an inlet, and a shaft. The first chute section has a first ramp and a first drop. The second chute section has a second ramp, a second connector, and a second drop. The first ramp has a plurality of first openings, a first ramp top edge, and a first ramp bottom edge. The first drop has a first drop top edge and a first drop bottom edge. The second ramp has a plurality of second openings, a second ramp top edge, and a second ramp bottom edge. The second connector has a second connector top edge and a second connector bottom edge. The second drop has a second drop top edge and a second drop bottom edge.

A mailbox with a housing, a floor and a receptacle situated on top of a sliding rail assembly affixed to the floor. A first bracket is affixed to the inside surface of the door and connected to a first U-shaped bracket with a downwardly facing open part. The two legs of the first U-shaped bracket are pivotally attached to longitudinal rods extending underneath the mailbox. The distal end of each longitudinal rod is pivotally attached to a second U-shaped bracket with a downwardly facing open part. A first end of a traveling rod extends upwardly from the lateral part of the second U-shaped bracket, and a second end of the traveling rod is attached to a shaft. A wheel bearing is situated on either end of the shaft, and a receiving bracket is attached to the rear wall of the receptacle and configured to receive the wheel bearings and shaft.

An adjustable and lockable mailbox includes a body; a door affixed to a front portion of the body, the door having a mail slot; a platform positioned below the body, the platform providing horizontal movement of the body; a vertical telescopic post attached to the body, the vertical telescopic post providing vertical movement of the body; and a lock mechanism inside the body to secure the door to the body. The mailbox also may include at least one solar panel and/or a battery/electronic box affixed to the body to power the lock mechanism, the platform, and/or the vertical telescopic post. The interior of the body may be watertight when the door is in a closed position. The mailbox may include a camera and/or remote locking.
