Embodiments generally relate to hinge mechanisms. Many of the hinge mechanism embodiments may be used in foldable furniture. The foldable furniture may be a foldable seat or table. The hinge mechanism may include a central cylinder with a body defining a hinge axis. The central cylinder may have rotate channel(s) transverse to the hinge axis and locking channels extending axially from the rotate channel(s). Collar(s) may couple with the central cylinder and may include pin(s) that protrude inwardly into the rotate channel(s) and locking channel(s) of the central cylinder. In some embodiments, an intermediate cylinder may be disposed between the central cylinder and the collar(s). The intermediate cylinder may have slots corresponding to the rotate channel(s) of the central cylinder. When pin(s) and locking channel(s) are aligned, the central lock cylinder may move axially to lock the collars in a desired angular position (e.g., a deployed or folded configuration).

A hinged mechanism includes: panels; and hinges connecting respective pairs of the panels to each other in a closed loop so that the hinged mechanism is non-planar, wherein at least one of the hinges is a rolling-contact hinge. All of the hinges can be rolling-contact hinges. The closed-loop hinged mechanism can comprise at least four hinges, each of the at least four hinges being a sole connection between a respective adjacent pair of the panels. A cross section of rolling surfaces of the rolling-contact hinge can be circular. A cross section of rolling surfaces of the rolling-contact hinge can be non-circular.

The present embodiments relate to a hinge for use in a mobile toilet having a toilet bowl, a toilet seat, and a toilet lid, wherein the toilet seat and the toilet lid each are swivel-mounted to the toilet bowl by the hinge and have a common pivot axis. Furthermore, the present embodiments relate to a damping device for retrofitting a hinge. The present embodiments also relate to a mobile toilet. In particular, the present embodiments relate to the problem to allow an easy retrofitting of a hinge and mobile toilets, respectively. This problem is in particular solved with the initially described hinge that in accordance with the present embodiments has at least one receiving area that is formed to receive at least one damping device for damping the swivel motion of the toilet seat or the toilet lid about the pivot axis.

An intelligent hinge determines motions of a swinging door. The hinge has an accelerometer secured to a leaf of the hinge. As the door swings, the leaf also rotates and the accelerometer determines an acceleration value. A velocity of the swinging door may be determined from the acceleration value. An initial, instantaneous, and final angular position of the door may also be determined from the acceleration value.

A storage compartment comprising a housing, a lid, a lid damper, a storage tray, and a tray damper. The lid damper pivotally couples the lid to the housing about a pivot axis such that the lid is moveable between an open position and closed position. The tray damper pivotally couples the storage tray to housing about the pivot axis such that the storage tray is moveable between a lowered position and a raised position independent of the lid.

A door assembly for selectively interlocking opposing doors each pivotably mounted at a hinge side thereof to a door frame so as to both open and close in the same direction includes a door handle assembly mounted to one door at a latch side thereof opposite the hinge side and carrying a first plurality of magnets, and another door handle assembly mounted to the other door at a latch side thereof opposite the hinge side and carrying a second plurality of magnets. The door handle assemblies are arranged relative to each other with the first and second pluralities of magnets aligned such each aligned pair of the first and second pluralities of magnets have opposite magnetic polarities, and the aligned first and second pluralities of magnets magnetically couple to each other as the door handle assemblies are brought into contact with each other.

A single-axis hinge includes a base, a movable plate, a limiting block, a rotating shaft and a stand set. The base includes a first shaft mounting hole, a stand drive shaft mounting hole and a path. The movable plate is formed with a second shaft mounting hole and a limiting notch. The limiting block is installed in the path. The rotating shaft passes through the first and second shaft mounting holes and includes a driving block and a first cam. An edge of the driving block is formed with a transmission teeth portion not completely surround the edge. The stand set includes a stand drive shaft disposed in the stand drive shaft mounting hole, and a support stand driven by the stand drive shaft. The stand drive shaft includes a gear and a second cam formed with a positioning notch.

For a vehicle with at least one removable hardtop roof panel and a fixed hardtop rear rooftop, a hinge is provided that attaches to the removable panel(s) and the rear rooftop. In the case of the Jeep® Freedom Top®, both removable panels are attached to the rear fixed portion of the roof using the hinge, enabling the removable panels to be flipped over the rear of the roof.

A hinged mechanism includes: panels; and hinges connecting respective pairs of the panels to each other in a closed loop so that the hinged mechanism is non-planar, wherein at least one of the hinges is a rolling-contact hinge. All of the hinges can be rolling-contact hinges. The closed-loop hinged mechanism can comprise at least four hinges, each of the at least four hinges being a sole connection between a respective adjacent pair of the panels. A cross section of rolling surfaces of the rolling-contact hinge can be circular. A cross section of rolling surfaces of the rolling-contact hinge can be non-circular.

An overtravel hinge for a sliding door of a vehicle. The overtravel hinge expands from a collapsed condition, to a partially deployed condition, and to a fully deployed condition. The hinge includes a four bar linkage utilizing an arm to control movement of the overtravel hinge between the collapsed condition and the fully deployed condition. The overtravel hinge, in one embodiment, is used to modify or retrofit a known original equipment manufacturer vehicle.
