A combination door guide and protector can be used to safely and easily attach or remove vehicle doors. A set of two guides can be used for each door. Each guide can include a forward curved portion and a second curved portion that extend outwardly away from a body and form a groove. Each guide also includes a crenellated void. A body can connect the two guides and can extend away from each side of the curved portions to provide protection to the vehicle frame and body. The crenellated voids can be placed on top of weldments of hinge pin receivers located on the vehicle body frame. Hinge pin housings on the vehicle door can be slid within the groove until hinge pins on the door engage with the hinge pin receivers. The combination device makes it easier to align the hinge pins with hinge pin receivers.

A security door assembly is disclosed including a hinge assembly having a first hinge plate having at least a first hinge pin receptacle extending from the first hinge plate, and a second hinge plate having at least a second hinge pin receptacle extending from the second hinge plate. A hinge pin is removably received in a longitudinal direction within the first and second hinge pin receptacles such that the first and second hinge plates are pivotal with respect to one another via the hinge pin. The hinge assembly includes a bearing assembly disposed between the hinge pin and one of the first or second hinge pin receptacles, and a retention member removably extending in a first lateral direction into one of the first or second hinge pin receptacles and engaging the hinge pin.

A mortise jig assembly includes a block that is longitudinally elongated. The block has plurality of mortises therein and the block is clamped to a face of a door such that selected ones the mortises is aligned with an edge of the door. A jig panel is provided and the jig panel is positionable against the edge of the door to engage respective ones of the mortises thereby retaining the jig panel at a selected location on the edge of the door. The jig panel has a guide hole therein thereby facilitating the guide hole to be aligned with a preferred location to cut a hinge recess in the edge of the door. A pair of bolts is each extendable through the jig panel and the block for attaching the jig panel to the block.

An eyewear device provides for routing a flexible conductive element or conductor through a hollow interior of a hinge mechanism that connects a temple of the eyewear device to its. The hinge mechanism comprises a pair of hinge pieces that defines a composite conduit through the hinge mechanism, conduit and hence the conductor routed through the passage being hidden or obscured from external view in any operational position of the hinge mechanism.

A hinge assembly for a hood of a vehicle is provided. The hinge assembly includes a body member and a hood member. The hood member is pivotally coupled with the body member through a pivot pin. The hood member or the body member partially wraps around the pivot pin such that the hood member or the body member defines a notch. The hood member or the body member is adapted to disengage from the pivot pin on application of an impact force on the hood member.

Apparatuses, systems, and methods for absorbing energy in a hinge are provided. An apparatus may include a first portion, a second portion coupled to the first portion to move relative to the first portion, and a tab configured relative to the first and second portions to absorb energy imparted to the second portion during a collision. The tab may be bendable via rotation as the second portion moves towards the first portion during the collision. The first portion may be a hinge bracket securable to a vehicle body. The second portion may be a hinge arm securable to a vehicle hood. The tab may be positioned at least partially between the first portion and the second portion for selective interference of the tab with one of the first portion and the second portion.

An embodiment system for illuminating a charging port of an electric vehicle is provided. The charging port is provided in a vehicle body for supplying electrical power to a vehicle driving battery, and the system includes a charging port door configured to open and close the charging port, and a lamp device disposed on the charging port door and configured to illuminate the charging port.

A foldable screen and a shower room are provided. The foldable screen includes a transmission gear mechanism and a plurality of panel bodies arranged in sequence. End portions of two adjacent sides of two adjacent panel bodies enclose to form a mounting opening into which the transmission gear mechanism is installed for realizing folding and unfolding of the plurality of panel bodies. The transmission gear mechanism includes a housing having a receiving cavity therein, the housing being installed in the mounting opening; a first gear located in the receiving cavity and installed on one of the two adjacent panel bodies; and a second gear meshed with the first gear, the second gear being located in the receiving cavity and installed on the other of the two adjacent panel bodies.
