Abstract:
Disclosed herein is an automatic closing apparatus for a sliding apparatus. The sliding apparatus comprises a fixed rail, a movable rail, and the automatic closing apparatus. The automatic closing apparatus includes a body, a slider, a housing, a damping unit, and an elastic body. The body is provided on the fixed rail and has an actuating space therein. The body includes: a guide wall that is provided in the actuating space and includes a curved guide part and a linear guide part; and a receiving space formed adjacent to the curved guide part. The slider is locked to or unlocked from a locking member of the movable rail and slides in an open or close direction under guide of the guide wall. The housing is coupled to the body. The damping unit is installed in the housing. The elastic body is fastened to the housing and the slider.
Abstract:
A door closer with an electric motor-assisted closing feature, that may generate its own power to assist in closing, and controls the speed of opening and closing of the door during generation is disclosed. Embodiments of the present disclosure are realized by a motorized door closer that electrically creates a latch boost force for a closing door. The door closer includes a motor disposed to operatively connect to a door so that the door will moved toward closed when the motor moves, and a position sensor to determine a position of the door. A processor is programmed to exert a closing force on the door in the latch boost region or when it otherwise detects that a motor assist is needed.
Abstract:
A snap hinge with damped closure is provided, including a first articulated quadrilateral and a second articulated quadrilateral which share a first lever and a second lever and are provided respectively with a plate for coupling to a first element and with a plate for fixing to a second element. The hinge is movable alternately between an open configuration and a closed configuration, in which the plates have different arrangements with respect to each other. At least one damping element is interposed at least between the first quadrilateral and the coupling plate or between the second quadrilateral and the fixing plate for damped transition from the open configuration to the closed configuration or vice versa.
Abstract:
A device for sliding door leaves with co-planar closure, particularly for furniture and the like, including a bracket system for connection to each one of the door leaves and with which a first pair of wheels is associated in a lower region.The device includes a second pair of wheels which are, together with the first pair of wheels, slideably engaged with the head respectively of a first guide and of a second guide which are T-shaped in cross-section, arc-shaped in plan view and the stem of which protrudes from the top of the piece of furniture.
Abstract:
A movable body assist device includes a contact receiving body provided in one of a support body or a movable body relatively moving to the support body; a base body supported on a rail provided in one of the support body or the movable body relatively moving to the support body; a hanging wheel including a base provided in the other of the support body or the movable body and a roller supported in the base, and rotatably moving inside the rail, and suspending the other of the support body or the movable body movably on the rail; a contact body formed to swing in a first direction relative to the base body, and formed to engage with and disengage from the contact receiving body; an urging mechanism urging the contact body; and a connection portion connecting the base body to swing relative to the base of the hanging wheel.
Abstract:
The present disclosure relates to a sliding door arrangement with an attenuation and retraction device facilitating soft-closing of a sliding door. The arrangement includes an attenuation and retraction device, which may be placed in the extension of a rail guiding and retaining the door, and a pin that extends from the door and interacts with the attenuation and retraction device. The pin may optionally be locked in a retracted position during mounting of the door in order to protect the pin from damage resulting from excessive side forces.
Abstract:
A power boost assembly is disclosed that can be used with a door actuator, such as a door closer. The power boost assembly is structured to store an energy during a first movement of a door and release the stored energy during a second movement of the door. In one form the power boost assembly can be structured as a module that can be added to an existing door and door closer installation. In one form the power boost assembly is used to increase a closing force imparted to a door to ensure a latching event.
Abstract:
A door closer has a housing for connection to a door and a drive spindle (10) coupled to the door. As the door moves the spindle (10) and housing (11) rotate relative to one another. The relative movement is translated by a piston and cam mechanism (21, 22) into a force that is used to separate a pair of magnets (28). The magnetic attraction of the magnet pairs (28) serves as a force to resist opening of the door and biases the door from an open to a closed position. At least one first magnet is coupled to the drive member and at least one second magnet (32) coupled to the housing. The magnets are arranged in the housing with their opposite poles facing one another such that there is a magnetic force of attraction between them. At least one further biasing spring (36) may be provided to provide a biasing force after the magnetic force has diminished by separation of the magnets.
Abstract:
A folding façade or folding awning arrangement includes at least two façade or awning elements, wherein a first façade or awning element is fixed on a building so that it can pivot about an axis, and wherein a second façade or awning element is pivotally held about a second displaceable axis and can be displaced along guides by means of a drive member, and wherein further a first collapsing edge of the first façade or awning element is pivotally connected to a second collapsing edge of the second façade and awning element to form a collapsing joint and can be moved in a manner released from the guides, collapsing transversely to the façade. The arrangement further includes at least one collapsible/fold-out and/or locking means. Safe operation is achieved in that at least one pivoting actuating element is provided in the form of a collapsing/fold-out, pulling/drawing, and/or locking means.
Abstract:
An adjustable snap-acting hinge is provided. The hinge includes a first articulated quadrilateral and a second articulated quadrilateral, which can move on a working plane and share a first lever and a second lever and are provided respectively with a plate for coupling to a first element and with a plate for fixing to a second element. A contrast element is associated with the coupling plate and can be arranged in at least one position for use, which lies between a first position in which the contrast element is arranged at a maximum distance from the point of the first lever, and a second position in which the contrast element is arranged at a minimum distance from the point of the first lever. The hinge also includes locking means for keeping the contrast element in the position for use.
