A window assembly for installing in a window opening of a building. The window assembly comprises a window sash pivotally mounted in a window frame such that the window sash can be pivoted between a closed position in the window frame and an open position. When the window sash is in the closed position in the window frame, the window frame and window sash have a flush exterior interface and a flush interior interface, between the window frame and window sash.

The present application relates to an opening and closing mechanism and a train having the same. The opening and closing mechanism comprise a driving device, a locking device and a support arm; the driving device is connected to the locking device to drive the locking device to rotate; a first end of the locking device is rotatably mounted on a baseplate; a sliding groove in which a second end of the locking device is slidably located is formed on the support arm; a first end of the support arm is rotatably mounted on the baseplate; a second end of the support arm is connected to a fairing; the driving device drives the locking device to rotate, the locking device drives the support arm to rotate by the sliding groove, so that the support arm opens or closes the fairing.

A sliding operator handle includes an actuatable brake providing at least one braking position in which the actuatable brake is configured to contact a track and restrict sliding motion of the track mount along the track and at least one sliding position in which the actuatable brake is configured to reduce contact with the track and allow sliding motion of the track mount along the track, and a handle pivotably coupled to the track mount. The handle is configured to receive a manual input force to slide the track mount in either direction along the track, and being further configured to actuate the actuatable brake in response to the manual input force. The handle includes a neutral position corresponding to the at least one braking position of the actuatable brake and actuation positions to allow sliding motion of the track mount along the track in response to manual input forces.

The present invention relates to the field of mechanical manufacturing technology, relating to a locking device. The locking device comprise a casing with a first end and a second end; a hole is formed on the first end, and the second end has an opening; a rod is provided within the casing; and a fastener is provided on the end portion of the rod outside the casing; a raised member located outside the casing is provided at a second end portion of the rod, the raised member having a diameter greater than a diameter of the opening and a gap being formed between the raised member and the casing; a spring is sleeved on the rod, and a first shaft is provided at the second end portion. An opening and closing mechanism having the locking device is further provided for the opening or closing of a fairing.

A casement window opening control device including a sash sub-assembly and a frame sub-assembly. The device is self-locating by aligning the bottom end of each sub-assembly with physical features of the window. This saves time and effort in installation by not requiring any measurements to ensure that an engaging feature of the limiting arm of the device is aligned with an engaging feature of the frame sub-assembly so that the device properly reengages upon closing of the sash after release. Also, operation of the release of the travel limiting arm is intuitive, requiring only pressing in on a latch button and sliding it upwardly to effect release.

The invention discloses an anti-theft window which is convenient for emergency escape of middle and high-rises, and includes a wall. The wall is provided with a housing space. There is a lower window sill, the rear end surface of the lower window sill is fixed on the wall body, the upper end surface of the window is fixed with a left-right symmetrical retaining wall, and an anti-theft window is provided between the retaining walls. The device and the locking device can detachably and stably install the window frame on the front side of the window, which can ensure the safety of the personnel inside the room. Secondly, in the event of an emergency, the window frame is detachable to facilitate outdoor personnel to enter the room for rescue, and the window frame It can be used as a flat board, and people in the room can ride on the window frame and land on the ground through fire protection ropes to escape.

A secondary window system installable within a primary window frame that includes a top horizontal member, a bottom horizontal member spaced from the top horizontal member, and first and second side members, the secondary window system including a top channel member attachable to and extending along at least a portion of the top horizontal member of the primary window frame, a secondary window frame comprising a header, a sill spaced from the header, first and second side jambs spaced from each other and extending from the header to the sill, and a secondary window opening defined by the secondary window frame, a top channel retainer engageable with the header of the secondary window frame, and at least one hanger engageable with the top channel member and the top channel retainer, wherein the secondary window frame is rotatably moveable relative to the primary window frame about the at least one hanger.

A fenestration unit comprising a frame having a center, a sash coupled to the frame, an interior pane coupled to the sash, a spacer coupled to the interior pane, an exterior pane coupled to the sash and the spacer, the exterior pane including an inward-facing surface, and a peripheral shield disposed on the inward-facing surface of the exterior pane such that, when viewed at direct angle, the peripheral shield hides the spacer, the sash, and at least part of the frame.

A structural member for a window comprising two extrusions spaced apart and coupled to each other using an insulating coupler extending at least 40 mm apart to form the structural member and hinder thermal bridging. A stiffener extends inside the structural member between the extrusions to stiffen the structural member and comprises two spaced apart ends engaged with the two extrusions, respectively. The two ends are coupled to each other using an insulating stiffener coupler to support the stiffener and hinder thermal bridging. A method of forming a thermally broken structural member.

A door system including a primary door molding attachable to a primary door frame, the primary door molding including a first vertical member and a first hinge member extending from the first vertical member. One of a horizontal member from which the first vertical member downwardly extends and the first vertical member includes a first rotatably engageable element, and the first hinge member includes a second rotatably engageable element vertically spaced from the first rotatably engageable element.
