Disclosed herein is a fenestration assembly. The assembly includes a movable sash assembly, a first lock counterpart connected to the movable sash assembly, a fixed sash assembly, a second lock counterpart connected to the fixed sash assembly, and a sill configuration. While the fixed sash assembly is mounted to the sill configuration, and while the movable sash assembly is mounted to the sill configuration at a first height, the movable sash assembly is lockable to the fixed sash assembly. While the fixed sash assembly is mounted to the sill configuration, and while the movable sash assembly is mounted to the sill configuration at a second height, the movable sash assembly is lockable to the fixed sash assembly. While there is an absence of locking between the movable and fixed sash assemblies, the movable sash assembly is movable relative to the sill configuration.

Disclosed herein is a roller assembly for a sliding panel, the roller assembly including at least one roller sub-assembly having at least one roller wheel, the roller sub-assembly comprising at least one pivotal arm and a roller wheel rotatably mounted to the arm, wherein one end of the arm is configured for pivotally attachment to the support to permit the arm and roller wheel to pivot relative to the support in a vertical plane and the opposite end of the arm has resilient suspension means configured to allow resilient pivotal movement of said opposite end relative to the support when a force is applied to the roller wheel.

A pivot bar in the nature of a screw with a head and a threaded portion for lateral adjustment at the site of a window installation is provided. A receiver is integrally formed in the bottom rail of a window sash, the receiver defined as a channel sized and shaped to frictionally engage with the threaded portion of the screw to structurally support the pivot bar during use. The pivot bar is rotatably engaged to position the threads within the receiver and laterally adjusted relative to the distance between the window sash and the window jamb such that the screw head mates with the pivot bar shoe associated in the corresponding window jamb, accounting for any measuring variances between the window jamb and the window sash. A method of installing a laterally adjustable pivot bar is also provided.

Power window operators, windows including the power window operators, and methods of using the same are described herein. The power window operators may offer the ability to control the timing and/or speed of the lock/unlock motion relative to the open/close motions of the operator arm of the power window operator and, if provided, a sash being driven by the power window operator.

Described is a hinge for doors or windows comprising: a first fixed body (5) associated with a fixed frame (1) and having a first axis (X1) of fixed articulation and a slot (6) made parallel to the axis (XC) of longitudinal extension of the first fixed body (5); a second movable body (7) connected to a movable sash (2); a first lever (8) having a first end articulated to the first fixed body (5) about the first axis (X1) of fixed articulation, a second end articulated to the second movable body (7), defining a second axis (X2) of articulation, and an intermediate zone; a second lever (9) having a first end articulated inside the slot (6) of the first fixed body (5) to define a third slidable axis (X3) of articulation, a second end articulated to the second movable body (7) defining a fourth axis (X4) of articulation and an intermediate zone; the first (8) and the second (9) levers are articulated to each other in the corresponding intermediate zone to define a fifth axis (X5) of shared articulation; means (10, 11) for adjusting at least one between the first axis (X1) of articulation and the third slidable axis (X3) of articulation along at least a first horizontal axis (XR1) parallel to the axis (XC) of longitudinal extension of the first fixed body (5) or a second horizontal axis (XR2) perpendicular to the axis (XC) of longitudinal extension of the first fixed body (5); the adjustment means (10) comprising a slide (12) positioned on the first fixed body (1) and having a first constraining portion for the first axis (X1) of articulation and a second portion connected to an adjustment axis (X12), parallel to the first axis (X1) of articulation, using a rotary element (13) configured for moving the slide (12), in both directions and along the first horizontal axis (XR1), in such a way as to vary the distance (D) between the adjustment axis (X12) and the first axis (X1) of articulation along the first horizontal axis (XR1), in both directions.

A sash (62) of a window opening up to 180° and capable of tilting is mounted onto a fixedly installed frame profile (63) and houses a pair of superimposing sashes that fit tightly therein when in closure position, i.e. an upper stationary sash (65) and a lower movable-divertible sash (64), each of the sashes (64,65) provided with laterally extending shafts (49) for connection with sash (62), roller wheels (50) provided onto the shafts (49) of sash (64) that roll within a predefined path created by insert guide profile members (19) and diverter guide members (66,68) to alternately bring sash (64) in a position of superimposing sash (65) and a position of alignment with the same. Lifting mechanisms (46) provided with a regulatory screw (84) for adjusting the pretension of a spring component thereof and thereby the force required by the user for moving the sash (64) are installed within the vertically extending sides of the sash (62).

A crank handle assembly for actuating a panel of a fenestration unit relative to a frame includes an arm. The arm is elongate and is configured to be supported at one end by the frame for rotation to actuate the moveable panel relative to the frame. The crank handle assembly also includes a knob that is moveably attached to an opposite end of the arm and that extends therefrom. The knob is supported for movement between an aligned position and a misaligned position relative to the arm. The arm and the knob cooperatively define a crank handle longitudinal axis. The knob, in the aligned position, is aligned with the arm and the crank handle longitudinal axis is straight. The knob, in the misaligned position, is misaligned with the arm, and the crank handle longitudinal axis is nonlinear.

A fenestration unit controller can be used to control automated opening or closing of fenestration units such as windows. The controller can be configured to receive an environment comfort target characteristic for an indoor environment. The indoor environment can include a fenestration unit that can be remotely controlled. The controller can be configured to receive atmospheric status information about the outdoor environment, and information about a solar loading offset for the indoor environment. The controller can determine a difference between the atmospheric status information and the environment comfort target characteristic. The controller can control the fenestration unit, such as to open or close the unit, based on the solar loading offset for the indoor environment and on the determined difference between the atmospheric status information and the environment comfort target characteristic.

A geared motor is provided, including an electric motor, a transmission, a drive shaft and a switching device arranged on the drive shaft. The switching device includes a single housing that is distinct and separate from an electric motor housing and a transmission housing. The switching device also includes a contactless, absolute position-measuring device and an evaluation unit, each provided within the single housing, a gear wheel coupled to the drive shaft, and an output unit. The switching device is coupled to the position-measuring device by a pinion, which rotates about the same rotational axis as the drive shaft.

A window balance system includes a U-shaped channel with a first end and an opposite second end, and a balance element supported within the U-shaped channel. The balance element includes a fixed pulley block coupled to the first end of the U-shaped channel, a movable pulley block movably disposed in the U-shaped channel, and a cord extending between the fixed pulley block and the moveable pulley block. The window balance system includes a locking device coupled to the fixed pulley block and configured to engage with the cord and lock a position of the fixed pulley block with respect to the cord. The window balance system also includes a shoe coupled to the second end of the U-shaped channel. The shoe includes an elongate portion and an enlarged portion such that the shoe is substantially T-shaped, and a chamber configured to receive at least a portion of a pivot bar.
