The embodiments herein provide a secure package delivery and pick-up system. The system comprises a security door with several collapsible storage compartments for accommodating packages meant for delivery or pick-up. The size of the compartments are configured to accommodate packages of different sizes and weights. The system enables secure delivery and return pick-up of packages at unmanned location by using security measures such as electronic key generation, biometric identification, RFID, video cameras. The user is facilitated to monitor the delivery and pick-up activity remotely through a mobile application downloaded on the computing device. The system is easy to install and provides protection of the packages form theft or damages due to weather conditions. The system enables user to share secure electronic keys with other users for a predetermined duration for accessing the building through the secure door and for usage of the storage compartments.

A secure package delivery and pick-up system includes a security door having a frame, and one or more collapsible storage compartments affixed to the frame. The collapsible storage compartments are configured for accommodating packages. An electronic unit is mounted on the frame, and is configured for electronically controlling an operation for the collapsible storage compartments. A security device is connected to the security door and receives images of a physical object from a first camera, receives an indication from at least one security tether indicating movement of the at least one physical object, and provides an alert based on the indication of movement of the at least one physical object.

In one embodiment, a system, comprising: a damper assembly, the damper assembly comprising: a structural member; at least one door pivotably coupled to the structural member; a clip connected to the damper assembly and comprising plural spring end constraining segments; a spring comprising a first end and a second end, wherein at least the first end comprises a hook, the spring coupled at the first end to one of the plural spring end constraining segments and at the second end fixably coupled to the damper assembly, the clip configured to accept a hookable connection to the spring at any one of the plural spring end constraining segments, each of the plural spring end constraining segments constraining movement of the hook, when connected thereto, during opening and closing of the at least one door, wherein the spring is at a first tension when hooked to the one of the plural spring end constraining segments and at a second tension when hooked to another of the plural spring end constraining segments.

A smart entryway includes an entrance door assembly configured to allow users (e.g., residents) to enter and exit a first space (e.g., a residence) and a storage assembly configured to allow secondary users (e.g., deliverymen) in a second space (e.g., a porch) to store items for later retrieval by the users. A portion of the storage assembly may be optionally refrigerated or heated. A security assembly is provided between the entrance door assembly and the storage assembly. The security assembly includes an authentication device to authenticate users and secondary users and a locking device to unlock the storage assembly and the entrance door assembly upon authentication. The locking device is provided behind the authentication device and concealed from the second space. When a first door of the storage assembly accessible from the first space is opened, a second door of the storage assembly accessible from the second space is locked.

A latch assembly for mounting in an opening of a door and for releasably latching the door to a door frame. The latch assembly includes a housing that is mountable to the opening of the door. A lever is rotatably coupled to the housing between a deployed position and a retracted position. A lock plug is rotatably mounted within the housing, the lock plug having one end for receiving either a tool or key, and an opposite end having an engagement surface. A latching member is movably coupled to the housing, and is engaged with both the rotatable lock plug and the lever in the retracted position of the lever. A torsion spring biases the lock plug back to a starting position after the lock plug is rotated from the starting position using the tool or the key.

An access opening closure device is provided for enabling passage of food or medication into a confined space without providing direct access from within the confined space to outside of the confined space. The device includes a housing assembly including a body and a cover, and a slide assembly including an access door and a frame. The body defines a receptacle and first and second openings. The housing assembly is pivotally coupled to the slide assembly and is movable from an operative position to a stowed, non-operative position.

A panel assembly includes a panel mounting frame; a panel cover; and a hinge configured to connect the panel cover to the panel mounting frame. The hinge includes a hinge plate; a first pivot shaft disposed on a first side of the hinge plate and configured to be pivotally connected to the panel mounting frame; and a second pivot shaft disposed on a second side of the hinge plate and configured to be pivotally connected to the panel cover. The panel assembly also includes an elastic element configured to drive the hinge plate to rotate and disposed between the panel mounting frame and the hinge plate. The elastic element is in a compressed state when the panel cover is in a closed state relative to the panel mounting frame.
