Provided is a hinge device easy to machine and manufacture. A shaft guiding recessed section and a fitting recessed section are formed on a first face of substrate of a hinge device base. As a first position adjusting mechanism, a substrate side guiding section is provided on a bottom face of the shaft guiding recessed section, and a first adjusting shaft is provided between the substrate and a first movable member. A first shaft-side guiding section of the first adjusting shaft engages with the substrate side guiding section by being accommodated in the shaft guiding recessed section, and a first shaft part of the first adjusting shaft rotatably engages with the first movable member. A fitting section is provided in the first movable member, and the fitting section is inserted into the fitting recessed section so as to be able to slide in a first direction.

The invention relates to an aircraft door having a support arm (6) connected to a support forearm (9) by a first pivot connection (7) about a first pivot axis (8), the support forearm (9) being connected to the leaf (5) by a second pivot connection (10) about a second pivot axis (11) parallel to the first pivot axis (8). The support arm (6) is connected to the door frame (4) by two hinges (13, 14) each having a pivot (26, 27) for rotating the support arm (6) about a third pivot axis (12) which is parallel to the first pivot axis (8) and to the second pivot axis (11), this pivot (26, 27) being connected to the door frame (4) by an attachment (22, 23) that is translatably adjustable in two directions (35, 37, 43, 47) orthogonal to one another and orthogonal to the third pivot axis (12).

A displaceable rotating shaft structure and a foldable device having the rotating shaft structure are disclosed. The displaceable rotating shaft structure comprises a support, a rotating shaft, a connecting rod assembly, a guide assembly, and a torsion assembly. The support has a supporting portion. The connecting rod assembly has a first outer end that is rotatably connected to the linking section of the rotating shaft and a second outer end that is pivotally connected to the supporting portion. The guide assembly has a guide rod. The guide rod is configured to displace relative to the supporting portion. When the rotating shaft is rotated, the rotating shaft drives the connecting rod assembly to adjust the angle and the total length of a joint of connecting rods of the connecting rod assembly, a distance between the rotating shaft and the support is changed through the guide assembly.

A hinge is provided, which comprises: at least one hinge pin defining a hinge axis in a first dimension; a hinge leaf; a housing comprising at least one recess for receiving a portion of the hinge leaf; and at least one user adjustable fastener arranged to enable user adjustment of the positioning of the hinge leaf within the at least one recess in a second dimension, wherein the second dimension is orthogonal to the first dimension.

A hinge mounting structure is provided whose appearance can be improved. In a hinge mounting structure including a hinge (1) having a first piece (3) and a second piece (4) that are coupled together via a shaft (2) in such a manner as to be rotatable relative to each other, the first piece (3) being mounted on a side jamb (6), the second piece (4) being mounted on a door (5), the side jamb (6) is provided with a protruding portion (8) protruding forward of a wall surface, and a center (C) of the shaft (2) is placed backward of a front surface line (X) of the protruding portion (8) of the side jamb (6).

A food service cart comprising a removable and adjustable hinge which accommodates for the normal inconsistences that are inherent with the rotational molding process. The hinge comprises a bore which is defined off-center relative to its longitudinal axis, allowing the bore to be selectively adjusted relative to a side panel and a door of the food service cart and provide a proper alignment there between. A plurality of facets disposed on the hinge ensure that it does not further rotate as the door is being rotated relative to the side panel. The food service cart also includes an expandable end table which forms a flush service with a side panel of the cart when in a collapsed or contracted configuration. A plurality of tray supports are disposed in the food service cart along with a flume defined therein which assists in the transfer of heat through the food service cart.

Described are various embodiments for coupling devices for dock installations.

Disclosed is a low profile, adjustable, soft close hinge comprised of a hinge cup pivotally connected to a hinge body via a hinge arm and a hinge link in a four-bar linkage arrangement. A spring biases the hinge to a closed position. The hinge body is adjustably connected to an inner frame with an overlay adjustment screw and depth adjustment cam. The inner frame releasably connects the hinge body to a mounting plate. A stop bracket is adjustably and slidably connected to the hinge body by a cam. The adjustable position of the stop bracket relative to the hinge body determines the point at which the damping functionality of a damper begins during a hinge closing movement. A linkage sub-assembly pivotally connects the damper to the hinge link.

A hinge mountable between a door jamb and an edge of a door panel has a jamb part set in the jamb, and a panel part fixed to the panel. A first link has one end pivoted at a first jamb axis in the jamb part and an opposite end pivoted at a first panel axis in the panel part, and a second link has one end pivoted at a second jamb axis in the jamb part offset from the first jamb axis and an opposite end pivoted at a second panel axis in the panel part. The axes all are substantially parallel and offset horizontally from one another. The two links are not connected directly to one another between their ends. The first and second links are U-shaped in a central section between their ends.

A hinge arrangement includes a first hinge plate assembly including a pivot housing movable about a pivot axis and including a threaded adjustment pin transverse to the pivot axis away from the housing. A second hinge plate assembly includes an adjustment housing, the adjustment housing including a threaded portion. The threaded adjustment pin is threaded into the adjustment housing to connect the first hinge plate assembly to the second hinge plate assembly. Relative rotation between the threaded adjustment pin and the threaded portion of the adjustment housing causes the second hinge plate assembly to move along a length of the threaded adjustment pin, altering a spacing between a mount plate portion of the first hinge plate assembly and a mount plate portion of the second hinge plate assembly. A connection between the pivot housing and the first hinge plate assembly may include a torsional and/or gravity closing bias.
