In a invisible hidden door hinge (1), a first connecting body (2a) and a second connecting body (2b) are connected together by an articulation device (3) which allows the relative movement between a condition of opening and a closed condition in which the first (2a) and the second (2b) connecting body define a seat in which the articulation device (3) is enclosed. At least one of the connection bodies (2a, 2b) comprises a support structure (4a, 4b) in which, for a position adjustment, at least one movable body (5a, 5b) is housed which is shaped from a respective single metal sheet in a single concave piece having concavity defined by a bottom (52a, 52b) and by side walls (53a, 53b) that realize a continuous peripheral edge of the bottom (52a, 52b), joined to the bottom (52a, 52b) without interruption of the material of which said respective single metal sheet consists of and surrounding the bottom (52a, 52b) on at least three consecutive sides.

A concealed hinge for a turn-tilt window with a fixed frame and leaf includes of a pair of scissors with a first arm and second arm, that are connected by a central hinge and which are hingeably connected by a first end to a mounting slat that is intended to be mounted on the frame, and have a hinge at a second end for coupling to the leaf. The first arm is connected by its first end to the mounting slat with a fixed frame hinge with a peg fastened to the mounting slat and the second arm is connected by its first end to the mounting slat by a shiftable frame hinge with a peg that is shiftably affixed in a guide slot of the mounting slat, whereby in the closed situation of the scissors, the mounting slat serves as a support for the tilting movement of these scissors.

An electronic device and a hinge assembly thereof are provided. The hinge assembly includes a first and a second fixed block, a first and a second polyline rod, a damper rod and a fastener. The first fixed block has a first and a second end, the second fixed block has a third and a fourth end, and the first polyline rod has a fifth and a sixth end, wherein the fifth end is connected to the second end, and the sixth end is connected to the fourth end. The second polyline rod has a seventh connected to the fourth end, and an eighth end, connected to the second end and the sixth end. The damper rod is slidably disposed on the first fixed block, the fastener is fixed to the first fixed block, and a distal end of the damper rod is fastened into the fastener.

A hinge has first and second leaf assemblies pivoted on each other and a link assembly interconnecting the first and second leaf assemblies. At least one of the first and second leaf assemblies has upper and lower mounts forming a cavity in which a respective end of the link assembly is pivoted, and at least one of the mounts of the one leaf assembly is formed with a recess opening into the cavity. According to the invention a body of foaming fire-protection material is provided in the recess so that when heated the body expands and fills the cavity with fire-protective foam.

The present invention provides a hinge structure, which comprises a first pivoting assembly, a second pivoting assembly and a first bracket. The first pivoting assembly comprises multiple first piston components, multiple first pivoting arms and a first sliding shaft. Each of the first pivoting arms has a first elastic slot. A diameter of the first sliding shaft is greater than an aperture of the first elastic slot so as to generate a first torque. The first bracket has multiple first grooves separated from each other, and the first piston components are respectively disposed in the first grooves. When the first pivoting assembly pivots relative to the second pivoting assembly to an angle, the first grooves respectively press the first piston components so as to generate a second torque.

A parallel hinge (10) for holding an opening member in a frame. The hinge (10) includes a first arm (11) connected between a fixed pivot (16) mountable on one of the member and frame and a movable pivot (17) mountable on the other of member and frame. The hinge (10) includes a second arm (12) connected between a fixed pivot (18) mountable on the other of the member and frame and a movable pivot (19) mountable on the one of the member and frame. The arms (11, 12) being pivotally connected (13) intermediate their ends to allow a scissor action. One of the arms (12) has two portions (14, 15) such that one portion lies above the other arm at the intermediate pivot and the other portion lies below, such that on closing the arms can overlie one another. Each of the portions (14, 15) of the arm (12) has a first end mountable on one of the member and frame, and a second opposed end providing a load transfer member (22, 23) extending beyond the intermediate pivot (13). The load transfer member (22, 23) of each portion is engaged with the other portion in order to distribute the load uniformly across at least a portion of the arm (12).

The hinge (10) is intended for a roof window having a frame and a sash, and has a frame hinge part (100) and a sash hinge part (200) configured to assume an angle relative to the frame hinge part (100). Each hinge part (100, 200) has a base plate (110, 210) with a guide track (112, 212) and a link (120, 220), the links (120, 220) being connected to each other at a bearing axle (123). Each link (120, 220) has a first hinged joint (121, 221) to the respective base plate (110, 210) and a sliding joint (122, 222) slidably received in the guide track (212, 112) in the base plate (210, 110) of the other hinge part (200, 100). A pick-up element (130, 230) is connected to the base plate (110, 210) in a second hinged joint (131, 231) and is biased by a spring (140, 240) to act on the sliding joint (222, 122) in the guide track (112, 212), for instance within a predefined angle interval.
