Abstract:
In an acceleration and deceleration device which includes at least one energy storage device and a cylinder with at least one piston movably disposed in the cylinder and moved therein by a carrier element and a sliding door including a slidable door panel provided with an acceleration and deceleration device, a second carrier element is provided guiding either the first piston or the second piston for movement in the cylinder so as to control the movement of pistons and of the sliding door near its end positions.
Abstract:
A door closer for a top hung sliding door has a buffer mechanism and a trolley hanger. The buffer mechanism includes a stationary base, a sliding block, a hook, two buffers and two resilient members. The sliding block is slidably mounted on the stationary base. The hook is pivotally mounted on the sliding block. The buffers are mounted on the stationary base and each buffer has a piston rod secured to the sliding block. The resilient members are mounted on the stationary base and each resilient member has one end secured to the sliding block. The trolley hanger has at least one engaging recess selectively engaging the hook. Therefore, the buffers can provide a buffering force and the resilient members can release a resilient force to reduce a moving speed of a door panel.
Abstract:
A damper has at least two damping components which are mounted such that they can move relative to each other during a damping stroke. A damping medium acts between the damping components, and at least one actuating element is operatively connected to the first damping component at least during the damping stroke of the damper. A locking device is arranged between the second damping component and a retaining part. The locking device couples the second damping component fixedly to the retaining part during the damping stroke of the damper. During the return stroke of the damper, the locking device decouples the second damping component from the retaining part so as to realize a freewheeling motion such that, during the return stroke of the damper, the second damping component moves together with the first damping component.
Abstract:
A sliding device (13), guided on the ceiling (3) or under the floor (7) of a cabinet (1) with a rail element (19), which allows a sliding door (15) to be synchronously pulled away from the closet (1) in a parallel manner and then slid. In order to also guide the lower edge of the sliding door (15), the motion of the sliding door can be transmitted from the upper edge of the sliding door to the lower edge by a transmission shaft. No cavities or guide grooves have to be formed on the cabinet (1) or the floor (7), ceiling (9), side walls (3), or partition wall (5) thereof.
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 catcher (2) provided in a door frame H′ for capturing a striker body 1 moved from a near front side F when a door D′ is rotated toward a reference position; a braking device (5); and a linkage device (3) for both are provided. The catcher (2) is provided to be reciprocatingly rotatable between a standby position and a rotated position, captures the striker body (1) at the standby position, and rotates forward to the rotated position. Braking of the braking device (5) is applied to a rotation toward the rotated position of the catcher (2) through the linkage gear member (30).
Abstract:
To obtain a latch device for obtaining a great output load with a small input load.Holding parts (70) are provided on one end of holding members (64), and cam parts (72) are provided on the other end of the holding members (64), with a support part (68) of the holding members (64) as reference, and the cam parts (72) are moved away from each other by way of a rod (74), whereby the holding parts (70) are moved closer to each other. That is, the magnitude of the external force acting on the cam parts (72) can be changed by the movement of the rod (74), and the holding force of the holding parts (70) can therefore be changed with the support part (68) as a fulcrum. In other words, the stroke of the rod (74) and the position of the support part (68) of the holding member (64) are changed, and the distance from the support part (68) to the holding part (70) is made longer than the distance from the support part (68) to the cam parts (72).
Abstract:
A movable member moved forward to a predetermined position can automatically move further forward. The mechanism includes first and second connecting members provided in the movable member and an immovable member. The second connecting member includes a catcher for catching the first connecting member and an urging device for urging the catcher. The catcher is arranged to be able to move or relatively move along a moving direction of the movable member, and held in a waiting position while receiving an urging force by the urging device toward a forward movement direction or backward movement direction of the movable member. When the movable member is moved to the predetermined position, the first connecting member is retained by the catcher of the second connecting member, and upon releasing of retention, the movable member is automatically moved forward to the stopped position by the urging force.
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:
The invention regards to a mechanism for the aligned closure of sliding doors (1-3), in particular for furniture or compartments (V1-V3) with two or more doors, with a sliding door (1, 2 or 3) for each compartment, and where each compartment opens by sliding and overlapping of one door with one of the adjacent doors and closes in alignment with the adjacent doors. The mechanism consists of a single bracket (10) for each door, one end of the bracket (10) being fixed on the door, and its opposite end being equipped with a first sensing bearing (13) to run along a cam guide (70), said bracket (10) being suitable for inclination and transversal movement with a carriage (30), which also allows it to slide along a rail (50) to be positioned on the upper surface of the compartments. The carriage (30) can be adjusted transversally and the bracket (10) can move axially in relation to the carriage (30). An arm (14), one end of which is firmly attached to the bracket (10), while the other end (14a) is equipped with at least a second sensing device having a bearing (15, 15′), can run along an other longitudinal cam guide (60) using the same bracket (10) for inclination and movement.
