Described herein are systems, methods, devices, and other techniques for implementing smart windows, smart home systems that include smart windows, and user devices and applications for control thereof. A smart window, or photovoltaic window, may include a photovoltaic configured to generate electrical power from incident light onto the photovoltaic window, store the electrical power, and send the electrical power to an electronics package or various electrical loads including a wireless communication system, sensors, or window functions. The photovoltaic window may communicate with various smart home system devices such as hub devices and user devices, which may include the reception of control data at the photovoltaic window and the transmission of sensor data captured by the window sensors.

An emergency response cabinet including a housing and a front door. The housing having opposing side walls, a bottom wall, a top wall and a rear wall cooperating to define a receiving cavity therein and a front opening. The receiving cavity being configured to receive at least one piece of protective equipment. The front door is connected to the housing and moveable between a closed position and an open position. In the closed position the front door extends over the receiving cavity of the housing. In the open position the receiving cavity is unobstructed by the front door.

The present disclosure relates to a field of door/window hardware accessories, in particular to a door/window pulley, a pulley device, and a door/window. The present disclosure provides a bearing and an anti-deformation metal ring that can be in contact with a track, the anti-deformation metal ring uses its own rigidity to effectively avoid generating indentation, and the door/window pulley is also difficult to be pressed to cause deformation. Moreover, an inner part of an injection molded body is disposed between the bearing and the anti-deformation metal ring, which not only well transfers pressure bore by the anti-deformation metal ring when load-bearing to the bearing, but also restores the anti-deformation metal ring after slight deformation by giving an outward elastic support to the anti-deformation metal ring using elasticity of the injection molded body.

A sash includes a stile, the stile defining a first flange and a second flange, a locking slot defined extending through the first flange; and a sash guide, the sash guide defining a first guide leg and a second guide leg, the first guide leg defining a locking tab, the locking tab extending through the locking slot.

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 fenestration assembly comprises a frame having a first jamb and a second jamb parallel to and spaced from the first jamb; a movable sash movably mounted to the frame; a fixed sash fixedly attached to the frame; a plurality of clips coupling the fixed sash to the frame; and an adhesive connector securing an outer face of the fixed sash to the frame.

A sash includes a stile, the stile defining a first flange and a second flange, a locking slot defined extending through the first flange; and a sash guide, the sash guide defining a first guide leg and a second guide leg, the first guide leg defining a locking tab, the locking tab extending through the locking slot.

The present disclosure describes various embodiments of a concealed or hidden door closer that is installed in a drip cap of a door assembly. In some embodiments, the door frame and door closer components are configured to allow the door assembly to be readily installed as either a left or a right hand hinged door.

The invention relates to a vertical sliding element including an element frame and a sash which can be moved in the vertical direction relative to the element frame. In the closed position of the sash, one fitting chamber each is formed in the intermediate spaces which are laterally limited by mutually facing side faces of the sash and the element frame. Each fitting chamber is provided with a guide rail and guide elements guided in the guide rail. The sash is connected to the guide elements via a scissors' arrangement having a plurality of parking scissors. The scissors arrangement is designed for parallel parking of the sash in a partially open position, in which the sash is positioned in front of an opening in the element frame, seen in the horizontal direction, and wherein the guide elements are designed to move the sash parked in parallel in the vertical direction by moving the guide elements in the guide rails.

A fenestration assembly comprises a frame having a first jamb and a second jamb parallel to and spaced from the first jamb; a movable sash movably mounted to the frame; a fixed sash fixedly attached to the frame; a plurality of clips coupling the fixed sash to the frame; and an adhesive connector securing an outer face of the fixed sash to the frame.
