Abstract:
A door closer or operator includes a pivoting pinion on the door closer housing for transmitting door motion, and a cam connected thereto. A connecting member extends along a spring and engages the peripheral edge of the cam. Rotation of the cam causes a change in length of the portion of the connecting member between the position tangent to the cam peripheral edge and the spring second end to expand or compress the spring, resulting in a force transmitted along a longitudinal axis of the connecting member as a result of spring deflection. The cam peripheral edge has a profile with a varying radial distance between the cam axis and the connecting member at the position tangent to the cam peripheral edge such that the radial distance is changed as the spring expands or compresses to maintain a desired constant torque about the axis of the cam and pinion.
Abstract:
An assembly for opening/closing doors including at least a first wing, a second wing and a mechanism adapted to move the wings from a closing position wherein they lie in a vertical plane, to an opening position wherein they are arranged facing each other and lying onto parallel and substantially horizontal planes, and vice versa. The passage from the closing position to the opening position and vice versa occurs through a synchronized and simultaneous rotary-translating motion of the wings. The mechanism includes first and second kinematic arrangements respectively adapted to move the first and second wings, the kinematic arrangements being separate and distinct, kinematically connected through a mechanism for synchronizing and changing the transmission ratio to impart a differential trajectory to the synchronized motion of the first wing with respect to the second wing during closing and opening.
Abstract:
Presented herein is a novel sliding door system that that enables adjustment of at least two sliding doors relative to each other such that surfaces of the sliding doors create a substantially flush surface a support onto which the sliding door mechanism is mounted. The system includes at least one inner and outer sliding door slidably coupled to corresponding guide rails. The guide rail that is coupled to the outer sliding door is selectably moveable by a sliding door mechanism between a first and a second position. In the first position, a user can slide outer and inner sliding doors along said guide rails, whereas in the second position, a surface of the outer sliding door is substantially flush with a surface of said inner sliding door.
Abstract:
Self-closing device for sliding doors of the type comprising at least one sliding leaf (2) which is hung from an upper profile (3). Said device (1) comprises a drive belt (10) configured to be joined to the sliding leaf (2); a closing pulley (20), provided with elastic means (30), which is arranged on a first rotation axis (4) integral to the upper profile (3) and which engages with a first end (11) of the drive belt (10); and a brake pulley (40), provided with stopping means (50), which is arranged on a second rotation axis (5) integral to the upper profile (3) and which engages with a second end (12) of the drive belt (10) opposite to the first end (11), thus the rotation movement of both pulleys (20, 40) being connected by the drive belt (10).

Abstract:
The present invention relates to an assembly for opening/closing doors comprising at least a first wing (10), a second wing (20) and a mechanism (100) adapted to move said wings (10, 20) from a closing position wherein they lie superimposed on a same substantially vertical plane, to an opening position wherein they are arranged facing each other and lying onto parallel and substantially horizontal planes, and vice versa; the passage from said closing position to said opening position and vice versa occurs through a synchronized and simultaneous rotary-translating motion of the wings (10, 20). In particular, said mechanism (100) comprises a first and a second kinematic arrangement (1 10, 120) respectively adapted to move said first wing (10) and said second wing (20), said kinematic arrangements (1 10, 120) being separate and distinct, kinematically connected through means (200) for synchronizing and changing the transmission ratio to impart a differential trajectory to the synchronized motion of said first wing (10) with respect to the second wing (20) in the passage from said closing position to said opening position and vice versa.
Abstract:
A system of ejecting a sliding door of a closet, comprising a plurality of ejection assemblies and a connecting mechanism, which connects one assembly to the other. Each ejection assembly comprises a rail and a slidable member configured to slide along the rail, where the rail engages with a frame of the closet. The connecting mechanism allows synchronizing the ejection force applied upon the door at different locations of the door, by connecting the ejection assemblies through the connecting mechanism. This configuration allows ejecting and retrieving of the door outwardly and inwardly by sliding the slidable member of each assembly along the rail.

PROBLEM TO BE SOLVED: To prevent, in a drive unit 10 driving each of first and second driven members (sunroof and shade) provided in an opening formed in a fixed roof of a vehicle via first and second geared cables 8 and 9 respectively, the first or second driven member intercepted with power transmission from a motor 18 from moving due to impact when a vehicle collision occurs in a selective transmission state for selectively transmitting the power of the motor 18 to only one of the first and second driven members while switching between a state for transmitting the power of the motor 18 to both of the first and second driven members and the selective transmission state.SOLUTION: An output path of a motor 18 is divided into two parts, namely, first and second output shafts 22 and 42. Further, a drive unit includes first and second electromagnetic clutches 24 and 44 switching connection/interception of first and second pinion gears 23 and 43 in relation to the first and second output shafts 22 and 42. When intercepting each of the clutches 24 and 44, each of the pinion gears 23 and 43 is non-rotatably fixed to a frame 3.
