The invention discloses a folding and unfolding mechanism. The folding and unfolding mechanism is mounted between an upper panel and a lower panel which are hinged, and is used for folding and unfolding the upper panel and the lower panel, and for overturning for 0-180 degrees between the upper panel and the lower panel; wherein the folding and unfolding mechanism comprises a four-connecting-rod assembly, a pushrod assembly and an auxiliary connecting rod assembly; the auxiliary connecting rod assembly comprises a first auxiliary connecting rod and a second auxiliary connecting rod, wherein one end of the first auxiliary connecting rod is hinged to one end of the second auxiliary connecting rod; the other end of the first auxiliary connecting rod is hinged to the lower panel; and the other end of the second auxiliary connecting rod is fixedly connected with a fourth connecting rod. The invention provides a mechanism, mounted between an upper panel and a lower panel which are hinged together, for folding and unfolding the upper panel and the lower panel, and for overturning for 0-180 degrees between the upper panel and the lower panel.

A dual function door acts as both a pocket door and a hinged swinging door. A first door panel is hingedly attached to a wall for swinging. A first header rail is attached to the top of the first door panel while a second header rail is attached to an appropriate surface at the same height as the first header rail. A second door panel has rollers that slide within the first header rail. The first door panel is positionable so that the first header rail and the second header rail align allowing the second door panel to also slide within the second header rail. The two header rails can be locked in the aligned position.

A door latch assembly includes a housing, an inside and outside handle operably coupled with the housing, and a latch plunger. A latch cam is operably coupled with the inside and outside handles, and the latch cam further includes a crank arm slidably disposed against an inclined surface of a plunger leg operably coupled to the latch plunger. A biasing member urges the latch plunger to an extended position, wherein rotation of the inside or outside door latch handle in a first direction rotates the crank arm of the latch cam and displaces the plunger leg of the latch plunger and the latch plunger to a retracted position against the urging of the biasing member.

An emergency exit door assembly for a vehicle. The door assembly can include a door panel that is movably coupled to the wall of the vehicle. The door panel can have an inner surface and an outer surface. The door panel can be configured for selective movement between a closed position and an open position in which an opening within the wall is exposed. A headboard component can be incorporated into the door panel, and a bed pedestal within the vehicle can be positioned in proximity to the headboard component when the door panel is in a closed position.

A door latch assembly includes a housing, an inside and outside handle operably coupled with the housing, and a latch plunger. A latch cam is operably coupled with the inside and outside handles, and the latch cam further includes a crank arm slidably disposed against an inclined surface of an offset plunger leg operably coupled to the latch plunger. A biasing member urges the latch plunger to an extended position, wherein rotation of the inside or outside door latch handle in a first direction rotates the crank arm of the latch cam and displaces the plunger leg of the latch plunger and the latch plunger to a retracted position against the urging of the biasing member.

A method for controlling a motor vehicle locking mechanism and to a motor vehicle locking mechanism, in particular a motor vehicle door lock, comprising a control unit, at least one electric drive that can be controlled by the control unit, and at least one illuminant that can be associated with the locking mechanism, the illuminant being controllable in accordance with a status of the locking mechanism and/or of a vehicle component accommodating the locking mechanism, said status being detectable by the control unit, the illuminant being integrated into a switching circuit of the electric drive.

A motorized door assembly for a vehicle includes a housing having a housing body, a housing opening extending into a housing cavity, a door coupled to the housing and rotatable with respect to the housing about a pivot axis, a motor with a motor head fixed to the housing and a motor adapter rotatably coupled to the motor head about a rotation axis that is different than the pivot axis, and an arm coupled to the door and the motor. The housing cavity secures a component therein. The door conceals the housing cavity in a door closed position and reveals the housing cavity in a door open position.

The invention discloses a folding and unfolding mechanism. The folding and unfolding mechanism is mounted between an upper panel and a lower panel which are hinged, and is used for folding and unfolding the upper panel and the lower panel, and for overturning for 0-180 degrees between the upper panel and the lower panel; wherein the folding and unfolding mechanism comprises a four-connecting-rod assembly, a pushrod assembly and an auxiliary connecting rod assembly; the auxiliary connecting rod assembly comprises a first auxiliary connecting rod and a second auxiliary connecting rod, wherein one end of the first auxiliary connecting rod is hinged to one end of the second auxiliary connecting rod; the other end of the first auxiliary connecting rod is hinged to the lower panel; and the other end of the second auxiliary connecting rod is fixedly connected with a fourth connecting rod. The invention provides a mechanism, mounted between an upper panel and a lower panel which are hinged together, for folding and unfolding the upper panel and the lower panel, and for overturning for 0-180 degrees between the upper panel and the lower panel.

A recreational vehicle includes a body with an entryway to an interior of the recreational vehicle. A first door is coupled to the body via a first hinge and rotatable around a horizontal axis. A second door is coupled to the body via a second hinge and rotatable around a vertical axis.

A two door system for recreational vehicles or camper style trailers is disclosed including an interior door with a self-closing access panel for reaching a locking mechanism of an exterior door. The access panel provides a user the ability to reach and manipulate the latching mechanism of the exterior door from the interior of the vehicle even when the interior door is closed. A biasing member is disclosed that maintains the access panel in a closed position whenever an adequate opening force is not present. The access panel may take on a number of configurations and may be designed as a retrofit for existing door systems or as an original component. In a configuration, a vertically sliding movable panel portion may be provided, which defaults to a downward, closed position. In such embodiments, no biasing member may be needed (gravity may be sufficient for the movable panel portion to close).
