The invention relates to a three-dimensional adjustable hardware system. According to the invention, at least one of the hardware bodies (18) comprises at least one guide pin (28) for the purpose of adjusting the hardware system (10) in the z-direction and the housing, in which the at least hardware body is arranged, comprises at least one threaded pin (30, 32), wherein the guide pin (28) and thereby the hardware body (18) are moved relative to the housing in the z-direction when the threaded pin (30) is rotated. For the purpose of adjusting the hardware system in the x-direction at least one of the hardware bodies (16) accommodates at least one adjusting pin (34), which can be moved along the y-axis located in the xy-plane, and at least one surface (36, 38) of the adjusting pin (34) which is inclined with respect to the y-axis interacts with at least one sliding pin (40, 42), the movement of which along the x-axis located in the xy-plane being restricted by the housing (12) accommodating the at least one hardware body (16), and so the hardware body (16) can be moved relative to the housing (12) in the x-direction by adjusting the adjustment pin (34). For the purpose of adjusting the hardware system in the y-direction at least one housing (14) and the hardware body (18) arranged in said housing have at least one sliding guide (44) extending along the y-axis, along which the hardware body can be moved relative to the housing (14) in the y-direction.

A hinge has two housings adapted to be recessed in a door frame and a door edge and a link assembly extending between the housings and having ends pivoted in the housings. A vertically shiftable support body in one of the housings has a row of teeth extending horizontally in a first direction. A bearing block sitting on the support body forms a pivot for the respective end of the link assembly. A screw extending through the bearing block and threaded into the support body is tightenable to bear on and fix the bearing block on the support body. A gear captured in the seat of the bearing block meshes with the row of teeth and is rotatable to shift the bearing block on the support body in the first horizontal direction in an untightened condition of the screw.

Device for the closing and/or opening of a leaf, to be applied to a concealed hinge comprising two bodies articulated to each other through at least a pair of articulation arms and connectable respectively to a leaf and to a fixed structure, the device being intended to be associated with one of the two bodies of the hinge, the device including: a translating element engageable to/with an articulation arm of the hinge, at least one mobile group configured to cooperate with the translating element and which is mobile with respect to an element/structure which can be mechanically fixed to the hinge body to which the device is to be associated; elastic means acting on the mobile group to cause the movement of the mobile group and the translating element;
the translating element, the at least one mobile group and the elastic means are configured and reciprocally arranged.

A hinge for recessed installation between a door frame and a door panel has first and second housings adapted for recessing in the door frame and an edge of the door panel, a pair of links having ends pivoted in the housings and pivoted together about a vertical axis extending in a vertical direction perpendicular to mutually perpendicular first and second horizontal directions, and two supports in the second housing in which the respective ends of the links are pivoted. Respective adjusting screws extend in the second horizontal direction and are braced between the supports and the second housing such that rotation of each adjusting screws shifts the respective support in the second housing in the second horizontal direction. Respective pairs of guide faces spaced apart in the direction flank each of the supports.

A hinge for recessed installation between a door frame and a door panel that has first and second housings adapted for recessing in the door frame and an edge of the door panel, a pair of links having ends pivoted in the housings and pivoted together about a vertical axis extending in a vertical direction perpendicular to mutually perpendicular first and second horizontal directions, and two supports in the second housing in which the respective ends of the links are pivoted. A vertical connector body to which the supports are fixed is limitedly vertically movable in the first housing along with the supports and links. Respective pairs of guide faces on the connector body spaced apart in the vertical direction flank each of the supports.

A hydraulic hinge comprising a fixed element anchorable to a stationary support structure and a movable element anchorable to a dosing element. The fixed and movable elements are mutually coupled in such a way that the latter rotates with respect to the former about a first longitudinal axis between an open position and a closed position. One of the fixed element and the movable elements includes at least one working chamber defining a second longitudinal axis, which comprises at least one portion which includes: a plunger member sliding along the second axis and a working fluid to hydraulically dampen the movement of the movable element. The plunger member is mutually connected with one of the fixed element and the movable element so that the rotation of the latter corresponds to the sliding of the former and vice-versa.

A hinged flip cover mechanism of toilet seat cover, includes a main body, a toilet seat cover, and a hinge module. The toilet seat cover is connected to the main body via the hinge module. The hinge module comprises a first hinge crank and a second hinge crank, the first end of the first hinge crank is slidably coupled to the rear portion of the toilet seat cover, the second end of the first hinge crank is rotatably connected to the main body; the first end of the second hinge crank is slidably coupled to the main body, the second end of the second hinge crank is rotatably connected to the rear portion of the toilet seat cover; the central portions of the first hinge crank and the second hinge crank are pivoted to each other.

A vehicle door hinge apparatus including a door link having one end pivotably and slidably connected to a vehicle body side and the other end hinged to a door side, a vehicle body link having one end pivotably and slidably connected to the door side and the other end hinged to the vehicle body side, a door link guide provided on the vehicle body side and configured to guide sliding of the one end of the door link, and a vehicle body link guide provided on the door side and configured to guide sliding of the one end of the vehicle body link. The door link and the vehicle body link intersect each other, an intersection point of the two links is hinged, and the door link and the vehicle body link perform, when the door is opened, a scissors motion around the hinged intersection point.

Disclosed is a door hinge, comprising: a fixed body that is provided with a first connecting shaft and a second connecting shaft along the lengthwise direction therein; a linkage assembly of which both ends are respectively hinged to the fixed body and a movable body; the movable body that is provided with a sliding block capable of sliding along the depth direction of the movable body therein, one end of the sliding block being hinged to one end of the linkage assembly, and a straight track surface and an inclined track surface inclined towards the interior of the sliding block being provided at one side of the sliding block; and a self-closing mechanism that is provided on the side of interior of the movable body close to the straight track surface, has a telescopic structure, and has one end abutting against the side surface of the sliding bock.
