A hinge device for the rotatable movement of a closing element, such as a door, a window, a shutter or the like, between a closing position and an opening position, includes a fixed element anchorable to a stationary support structure; a movable element anchorable to the closing element so that the movable element rotates around a first longitudinal axis between a first opening position and a second closing position; a plunger that is operatively coupled to the movable element by a coupling system configured so that along a first section of the sliding of a connecting shaft, the plunger does not slide, thereby allowing a free rotation of the movable element, and along a second section of the sliding of the connecting shaft, the plunger slides integrally joined with the connecting shaft, thereby controlling the rotation of the movable element.

A gate assembly is formed from a gate attached by hinges to a jamb. A pair of L-shaped brackets are attached to the outer sides of the jamb. The brackets are in turn attached to a pair of gate posts in a barrier. Bolt holes formed in the header section of the jamb receive removable eye bolts that may be used as hoisting points as the jamb is being positioned within a barrier. To maintain the shape of the jamb during such positioning, a removable sill section is included in the base of the jamb. The first upright section of the jamb defines an unobstructed internal channel bounded by input and output portals. A cable may pass though the channel and into the gate by way of the output portal. Window openings in the gate may be fitted with removable window panels containing pickets and infill material. Dual gates may be positioned within an enlarged jamb, and a removable mullion post positioned between the gates and supported by the jamb.

A hinge for the rotatable movement of a door or a similar closing element anchored to a wall or to a similar stationary support includes a fixed element adapted to be coupled to the wall or similar stationary support and a movable element adapted to be coupled to the door or similar closing element. The fixed and movable elements are coupled to mutually rotate around a first longitudinal axis between an open position and a closed position. The hinge further includes a hydraulic duct with a calibrated passage for s working fluid and an adjustment system acting thereon to control the movement of the door or similar closing element.

A liquid sealed damper includes: an attachment portion attached to a peripheral portion of an opening of a vehicle or an opening and closing member for covering the opening; a contact portion to which an external force is input; an insulator configured to isolate vibration and connect the attachment portion and the contact portion; a main liquid chamber in which working liquid is sealed; an auxiliary liquid chamber having a wall portion formed of a diaphragm; and an orifice passage formed in the partition member and communicating with the main liquid chamber and the auxiliary liquid chamber. The partition member has a substantially circular surface forming a wall portion of the main liquid chamber. An opening portion at one end of the orifice passage is formed in the circular surface. The opening portion is formed to extend from an outer edge portion to a central portion of the circular surface.

First (3) and second (5) elements are mutually connected by a hinge pin (7). A transmission element (44) is interposed between the second element (5) and a cradle (53) end and includes elastic means (27) having an end connected to the cradle (53) end opposite to transmission element (44). An elongated first box member (41) contains, at least partially, the transmission element (44), the connected cradle (53) and the elastic means (27) whose end opposite to the cradle (53) is fixed to the first box member (41) transmitting the elastic closing force of the elastic means (27) to the second element (5). The cradle (53) contains a damper (57), each end of which has a respective transverse pin (58) whose ends slide in respective slots (54) formed in the cradle (53) and in respective slots (42) formed in the first box member (41).

An example door closer includes a casing and a pinion rotatably mounted to the casing. The pinion is operable to rotate through a plurality of movement zones, and the door closer is configured to exert forces on the pinion as the pinion moves through the plurality of movement zones. The door closer further includes a plurality of adjustment mechanisms, each operable to adjust the force exerted on the pinion as the pinion travels through a corresponding movement zone. The casing is provided with indicia that correlate each of the adjustment mechanisms to the corresponding movement zone.

To provide an opening and closing device for opening and closing body having a rotation torque controlling module and a torque peak adjusting module, solution was sought by an opened and closed body and the opening and closing body which comprises an attaching part, an opening and closing part rotatably attached to the attaching part via a hinge shaft, a rotation torque controlling module for controlling a rotation torque of the opening and closing part, a torque peak adjusting module for adjusting a torque peak of the opening and closing part at the time of its opening and closing movement.
