Abstract:
A covering of a building opening includes a rail, a first sash having a guiding slot, a second sash hinged with the first sash and having a center of rotation at an end thereof, a pulley assembly, and a restricting assembly. The pulley assembly is movably received in the rail and has a rod. The rod has a protrusion section extending out of the rail, and the protrusion section enters and leaves the guiding slot while the pulley assembly is moving. The restricting assembly has a moving member and a locking base. The moving member is provided on one of the first sash and the second sash, and the locking base is provided on the other. The moving member is moved by the rod and engages the locking base when the rod leaves the guiding slot.
Abstract:
A piece of furniture has an actuating arrangement for a flap of the piece of furniture. An actuating arm arrangement includes a lever arrangement for moving the flap and a main spring that acts in the closing direction (SR) to hold the flap closed. The piece of furniture also has an ejecting device for ejecting the flap in the opening direction (OR) by overpressing the flap in the closing direction (SR). At least one support spring acts in the opening direction (OR) and is separate from the ejecting device, and supports the ejecting motion of the ejecting device. At least in an overpressed closed position (US), the spring forces (A, U) are together greater than the closing force (Z) which acts on the flap and which is provided by the main spring acting in the closing direction (SR).
Abstract:
An item of furniture includes a furniture body, a furniture part which is displaceably received in or on the furniture body, and an ejection device having at least one ejection element for displacing the movable furniture part from a closed position into a first open position. At least one lockable drive device is provided for driving the at least one ejection element. A means is provided for displacing the at least one ejection element beyond the first open position.
Abstract:
The self-closing and opening device (1) particularly of a movable furniture part (103) comprises a fixed guide (8) having a supporting body (2) in which a first slider (3) can slide reversibly along a sliding axis (100) in opposition to and through the action of first elastic means (5), the first slider (3) being engageable with first driving means (106) present on a driving element (6) which slides reversibly in the direction of the sliding axis (100), the supporting body (2) comprising first movement means (4) for movement of the first slider (3) suitable to engage with guide means (12, 13) of the first slider (3), so as to release it from the driving means (106), also provided with a mechanical or elastically yielding stop (9, 120) against which the first slider (3) rests directly or indirectly before it engages with the guide means (12,13) in the first movement means (4) the driving element (6) being then pushed by an ejector (20) generating an initial opening movement of said movable furniture part (103).
Abstract:
The invention relates to an electric door-locking system to be applied to at least one electric door body that is movable in a sliding manner, and includes forwardly and reversely rotatable screws disposed side by side along a direction in which the electric door body slides at the side of a door frame; a cam assembly provided at a predetermined position of the screws to perform a locking function and an unlocking function; and a sliding unit provided with a locking roller resiliently biased in a direction toward the cam assembly and engaging with the cam assembly to perform the locking function, one end of the sliding unit being rotatably connected to the screw and the other end of the sliding unit being connected to the electric door body.
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 opening device for a door (16) of an article of furniture supported oscillatingly with respect to a body of the article of furniture by means of at least a hinge having elastic automatic closing means (14) comprises an expulsion organ (11) for the door (16) and a reloading mechanism of the expulsion organ (11), and is conformed such as to be applicable to a part from between the fixed part or the mobile part of the hinge, the reloading mechanism being operatively connected to one from between the expulsion organ and an element of the hinge which is mobile with respect to the reloading mechanism and being operatively and selectively connectable to another between the expulsion organ and the element of the hinge which is mobile with respect to the reloading mechanism during at least a part of the opening movement of the door (16) such as to cause a reloading movement of the expulsion organ (11).
Abstract:
A hand pulling drive mechanism includes a hand drive device and a shaft connected with the hand drive device. The mechanism further includes a gear pair, a rotation propelling device connected with the shaft, and an eccentric pulling device including a shaft pin placed on the shaft and a torsion jacket pivotally connected to the shaft and rotated relative to the shaft pin. The gear pair includes a drive gear sleeved on the shaft for switching, and a follower gear secured to a motor shaft. The rotation propelling device is connected with the drive gear. The torsion jacket and the drive gear pull the torsion jacket through eccentric rotation of the shaft pin when the shaft is rotated, so that the drive gear moves in an axial direction and the follower drive engages with and disengages from the drive gear.
Abstract:
A powerless helical locking mechanism for a door includes a screw with a variable lead angle connected with a power source, and a self-adaptive nut connected to the door. The helical slot of the screw is divided into a working segment with the helical lead angle greater than the friction angle, a closing segment with the helical lead angle smaller than the friction angle, and a transition segment between the closing and working segments. The power source actuates the screw to rotate bidirectionally.
Abstract:
A lock device includes a cam portion including a stationary-side cam; a rotor including a movable-side cam; a slide groove; a slide projection; an engagement projection; and a lock groove, in which the movable-side cam is disengaged from the stationary-side cam, so that the rotor rotates so as to allow the engagement projection that has been fitted in the lock portion to disengage from the lock portion. The urging device includes a spring, and a sleeve inserted to pass through a lower-side rod portion, positioned between the rotor and the spring, and also restricting a movement of the rod in a sliding direction in a lock position of the lock device (for example, a lock groove and an engagement projection, and the like).
