A hinge arrangement having a first hinge part and having a second hinge part, which are connected to one another such that they can pivot, a first hinge pin being formed on the first hinge part, on which a first hinge sleeve is pivotably mounted, which forms a first sliding bearing with the first hinge pin, a dimensionally stable support part being connected to the first hinge sleeve. A first axial protrusion is formed on a first axial end face of the first hinge pin, which engages in an arcuate first groove of the first hinge sleeve, wherein a circumferential first side wall of the first groove together with the first axial end face and an inner side of an end cover fixed at the end of the first hinge sleeve delimits a working space which is filled with a damping fluid for damping a relative movement of the first axial protrusion with respect to the first groove.

It is described herein a venting apparatus for an opening in a roof. The venting apparatus for an opening in a roof may comprise a structural frame, an adapter, a mount, a hinge, and a latch. The adapter may comprise a frame adapter section, a lip extending inwardly from a portion of the frame adapter section inner surface, and a protrusion extending upwardly from the lip. The frame adapter section may be configured to fit around an outer surface of the structural frame while the mount may be configured to fit around an outer surface of the protrusion. The latch may be configured to receive a signal from a device when the device detects the presence of smoke within the building to cause the latch to change from a latch closed position to a latch opened position.

A structure for assisting with opening and closing of a lower door includes a lower door having an upper end configured to be rotated open with respect to a bottom surface of a vehicle body, and a rotary unit configured to be fixed to the bottom surface of the vehicle body and configured to rotate in opposite directions to assist with opening and closing of the lower door.

A hinge is provided with two elements pivotally connected together for relative rotational movement about a hinge axis. The hinge has a spring formed of bent wire. The spring is mounted on one of the elements and a mechanism causes it to apply a biassing force between the two elements over at least part of their relative rotational movement. The biassing force is transmitted via a finger on the spring. A spreader is arranged to fit over the finger for engagement with the other element. The spreader extends continuously over the finger and engages substantially the whole of the finger.

A pivot hinge includes a spring housing with a central tube, a spring assembly, an upper mounting plate, and a lower mounting plate. The bottom end includes a knurled outer surface. A stop cam is positioned about the knurled outer surface and has an inner surface that conform to the knurled outer surface so that it may be positioned in a plurality of rotatable positions relative to the central tube. The stop cam also has an exterior surface which includes a detent. The different rotational positions of the stop cam upon the knurled outer surface changes the relative position of the detent in relationship to the central tube. A cam follower assembly is coupled to the lower mounting plate and has a cam follower plate with a cam follower that rides upon the stop cam and engages the detent recess to hold the door in an open position.

A pivot hinge includes a spring housing with a central tube, a spring assembly, an upper mounting plate, and a lower mounting plate. A pivot pin is positioned within the central tube and is coupled to a torsion spring. A top end of the pivot pin is received within a central channel of a spring bushing. The spring bushing has a cylindrical main portion and a undulating ridge forming three radially positioned high areas or tongues and three radially positioned low areas, troughs or grooves. The grooves are configured to receive or mesh with interior steps in the central tube to prevent relative rotation between the spring bushing and the central tube Each tongue also includes a spring mounting recess therein. The top end of the cylindrical main portion extends through and is journalled within the top opening of the central tube.

A hinge including: a first leaf assembly accommodating a portion of a first panel having a first cut-out section, the first leaf assembly including a first insert component which is tight fittingly receivable within the first cut-out section; a second leaf assembly, hingedly coupled to the first leaf assembly, for accommodating a portion of a second panel having a second cut-out section; one or more biasing components to bias the hinge toward a closed position; and a dampener to slow movement of the first and second leaf assemblies to the closed position, a first portion of the dampener is located within the first insert component and a second portion is configured to at least partially retract within the first insert component when coming into contact with the second leaf assembly during movement, a second portion of the dampener extends and retracts along an axis coplanar with the first panel.

A vehicle console assembly includes a body that defines a cutout. The cut out includes a contact surface. A lid is operably coupled to the body and includes a connector that defines an engagement member. The lid is operable between a raised position, a lowered position, and an intermediate engaging position therebetween defined by a predefined opening angle. The engagement member is space-apart from the context surface when the lid is in the lowered position and engages the contact surface when the lid is in the intermediate engaging position. A biasing member is disposed proximate the connector. A hinge pin extends through the cutout, the biasing member, and the engagement member.

A hinge including: a first leaf assembly accommodating a portion of a first panel having a first cut-out section, the first leaf assembly including a first insert component which is tight fittingly receivable within the first cut-out section; a second leaf assembly, hingedly coupled to the first leaf assembly, for accommodating a portion of a second panel having a second cut-out section; a spring operatively coupled to the first and second leaf assemblies to bias the hinge to move from an open position to a closed position; and a dampener to dampen movement of the hinge from the open position to the closed position, wherein said longitudinal dampener axis is disposed between and substantially parallel with planes defined by respective opposing faces of the first panel.

An aircraft panel system including a first panel, having a hinged coupling configured to couple the first panel to an aircraft structure, a second panel disposed adjacent to the first panel such that the first panel and the second panel together form cabin surface of an aircraft, and a latch mechanism configured to releasably couple the second panel to the aircraft structure, where the first panel is configured to pivot about the hinged coupling from a latched position to an actuation position to actuate the latch mechanism and cause a release of the second panel from the latch mechanism.
