Each of the parallel posts (3, 5) has a hollow interior (19, 23), and at least one of the first and second posts being movable toward and away with respect to the other. The retractable and extendable screen member (7) has first and second pairs of opposite parallel edges and is mounted between the first and second parallel posts (3, 5) at its first pair of parallel edges. The first flexible guide member (9; 109) extends along one edge of the second pair of parallel edges of the screen member (7) and between the first and second posts (3, 5) for retaining the one edge of the screen member (7). The first and second parallel posts (3, 5) each include a base profile part (69; 169) and an auxiliary profile part (71; 171) defining the hollow interior (19, 23) therebetween for slidably receiving the first flexible guide member (9). Optionally the auxiliary profile part (71; 171) is mountable to the base profile part (69; 169) in a selected one of two different positions in which it is connectable to the base profile.

Greenhouse comprising a roof construction, wherein the roof construction comprises a slanting upper surface, a first framework that defines a roof opening, and a rectangular ventilation window that covers the roof opening, wherein the ventilation window comprises a panel and a second framework along at least a distal front edge and two parallel side edges of the panel, wherein the greenhouse comprises a netting system to prevent passage of insects through the ventilation passage, wherein the netting system comprises an insect netting that covers the ventilation passage and that is pleated in a bellow configuration to collapse in a stacked manner, and a guiding provision for the insect netting, wherein the guiding provision comprises an elongate guiding bow between the first framework and second framework that extends along the insect netting, wherein the insect netting is slidably connected with the elongate bow.

The invention provides an attractive, easy to install, window screen that can fit the open window space adjacent to a window-mounted air conditioner for any nominally-sized window.

A fenestration system includes one or more of a light modulation controller or ventilation modulation controller. The light modulation controller is in communication with at least one light modulation element of a fenestration assembly having a frame and a panel. The light modulation controller includes a light prescription module configured to provide a specified light prescription for the building interior. A lighting difference module is configured to determine a prescription difference between the specified light prescription and ambient light. A dynamic light module of the light modulation controller operates the at least one light modulation element according to the prescription difference. The ventilation modulation controller is in communication with at least one operator configured to open and close the panel. A ventilation prescription module provides a specified ventilation prescription for the building interior, and a dynamic ventilation module implements panel closing and opening according to the specified ventilation prescription.

A screen assembly for a fenestration unit having a frame and a window sash, the screen assembly including a screen assembly frame having a first side member, a second side member, and an upper member, and a screen housing extending between the first side member and the second side member of the screen assembly, the screen housing having a first housing member and a second housing member, wherein the housing forms a screen retention space between the first and second housing members when the screen assembly is in a closed position, a screen positioned between the first and second housing members when the screen assembly is in the closed position, the pleated screen including a first end coupled to the first housing member and a second end coupled to the second housing member, and a catch element extending from the housing and configured to be coupled to the window sash.

An attachment assembly is provided for coupling a portable barricade to an overhead door, including a clamp, the clamp having a first surface and a second surface, the second surface facing the overhead door, a fastener passing through a clamp opening of the clamp and through an opening of the overhead door, a coupling member operably engaged with the fastener, and a biasing element positioned between the second surface of the clamp and the overhead door, wherein, when the coupling member is actuated in a first direction, the biasing element is compressed, shortening a distance between the clamp and the overhead door.

A screen system for use with a sliding panel of a window or door is used to screen an opening as the sliding panel or door is opened. The screen is attached to the edge of the sliding panel adjacent the opening, and is wound onto a spindle. The spindle is rotatably mounted adjacent the screen opening around which the screen is wound so that the screen can be unwound from or wound onto the spindle. A cord is connected between the sliding panel and the spindle pulley via an idler pulley. In this arrangement the spindle is caused to rotate so as to wind the screen back onto the spindle as the sliding panel is slid towards the closed position. While the screen is wound off the spindle, the cord is wound onto the spindle pulley and vice versa. As the A tension adjustment arrangement can also be provided that is configured to adjust the tension in the cable as the screen is wound and unwound from the spindle due to the change in diameter of the cord around the spindle pulley.

A window frame assembly has a built-in foldable screen, having a body, the body having at least a first frame part and a second frame part; the first frame part has at least a first end surface and a second end surface; the second end surface is fixedly connected to the second frame part; the first end surface is provided with a protruded guiding convex part; the guiding convex part is provided with a line receiving groove; and two sides of the line receiving groove are respectively provided with a concave part. The above structure has the benefits of enabling the guiding convex part located on the transverse frame in the foldable screen module to be re-assembled on the structure of the window frame assembly, thus reducing the number of foldable screen module components, and also improving the convenience of assembling the foldable screen module in the window.

A wire drawing tightness controller for an easily detachable and foldable screen, comprising: a connecting member, a wire drawing control device, a first connecting unit and a second connecting unit, wherein the connecting member is provided on a window frame, the wire drawing control device is provided with at least a control unit, and the first connecting unit and the second connecting unit are arranged between the connecting member and the wire drawing control device. By means of the arrangement of the first connecting unit and the second connecting unit, the wire drawing control device can be conveniently connected to the connecting member, and can also be easily separated from the connecting member, thereby enhancing the convenience of assembling a foldable screen.
