An exemplary door closer includes a body, a regulation screw, and an indicator. The body includes a surface and a cavity extending from the surface into the body, and the cavity includes an internal threading. The regulation screw is mounted in the cavity and includes an external threading engaged with the internal threading. The indicator is engaged with the regulation screw and positioned at least partially within the cavity. The indicator is positioned to project beyond the surface when the regulation screw is withdrawn to a reference position relative to the body.

A hydraulically damped actuator closes a hinged closure system. The actuator includes an energy storing mechanism that stores energy when the closure system is being opened and restores the energy to effect closure of the closure system. A hydraulic damping mechanism damps the closing movement of the closure system. The actuator further includes a tubular cylinder barrel with first and a second ends and a rotatable shaft with first and a second extremities. The shaft extends through the tubular cylinder barrel. Both extremities of the shaft are available to be connected with a mechanical connector that transfers rotation of the closure system to the shaft, which allows the actuator to be mounted in two opposing orientations depending on the handedness of the closure system.

Certain embodiments relate to an adjustment indicator mechanism for a door closer including a tubular portion and an adjustment screw mounted to the tubular portion. A housing is configured for mounting to the door closer, and includes a channel and indicia adjacent the channel, each of the indicia corresponding to a respective size of the door closer. An adjustment transmission includes a first component configured for coupling with the adjustment screw. An indicator transmission is engaged with the adjustment transmission and mounted in the housing. An indicator is movably mounted to the housing such that a portion of the indicator is visible via the channel. The indicator is engaged with the indicator transmission such that movement of the indicator transmission causes the indicator to selectively align with the indicia to thereby indicate the current size of the door closer.

An exemplary armature assembly is configured for use with a door closer comprising a pinion, and generally includes a first arm configured for rotational coupling with the pinion, a second arm pivotably coupled to the first arm at a pivot joint, and a hold-open mechanism. The hold-open mechanism generally includes a clutch having a decoupling and a coupling state, and an electromechanical driver operable to transition the clutch between the coupling state and the decoupling state. With the clutch in the decoupling state, a first torque is operable to cause relative pivoting of the arms. With the clutch in the coupling state, the first torque is inoperable to cause relative pivoting of the arms, and a second torque greater than the first torque is operable to cause relative pivoting of the arms.

A method for controlling a door, comprising the steps of storing energy during a manual opening of a door, sensing an object within a doorway, selectively applying a force derived from the stored energy, to close the door, based on the sensing of an object in the doorway. The closure is preferably controlled by an electronic control. A door closing device comprising an energy storage device for storing energy during door opening and releasing the stored energy to subsequently close the door, a damping system for damping a closure of the door, a sensor for detecting an object within a doorway, having an output, a controllable device for selectively restraining the energy storage device from closing the door, and a control system for controlling the controllable device based on the output.

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.

Mechanism for opening of a flap door of an item of furniture, including a part extensible telescopically under the action of a spring, hinged to a lateral side of an item of furniture and acting on a door by way of a thrust fulcrum, wherein a unit is provided, apt to move continuously the thrust fulcrum during the phases of opening and closure of the door.

This disclosure is generally directed to a hydraulic door closer, and more specifically is directed to a hydraulic storm or screen door closer that has a fluid overflow chamber providing fluid volume and pressure control for both expanded and contracted fluid at different temperatures. The disclosed hydraulic door closer comprises a fluid overflow chamber adapted to hold sufficient fluid to maintain required operating fluid or oil levels at different temperatures, and to ensure proper closer performance under both extreme high and low temperature conditions.
