A brake arrangement, for a retractable screen arrangement in which the a screen roller applies a retraction force to the screen and brake arrangement, includes a brake arrangement, for providing a braking force between the brake arrangement and a track which guides the brake arrangement, to resist retraction. The brake arrangement provides a brake member with a friction surface for contacting the bearing surface; a brake member support for supporting the brake member; and a forcing arrangement for forcing the friction surface against the bearing surface. The forcing arrangement includes a biasing arrangement for biasing the friction surface onto the bearing surface, and a force-increasing arrangement for increasing the force with which the friction surface engages the bearing surface. The force increasing arrangement converts a frictional force between the friction surface and the track into additional contact pressure force of the friction surface onto the guide track.

The present invention relates to a system for guiding a flexible curtain for at least partially closing an opening.

The system has a pleated net run by ropes that begin from the same side of the retention case, cross the net and continue upwards to all upper fixed horizontal guide, and are fastened at the upper part of the system. This invention uses wire rope which has one edge fastened at the upper truck, passes horizontally above the net, then parses through the pulley at the upper part of the sliding case, follows a vertical course towards the second pulley at the lower part of the sliding guide, crosses the lower fixed horizontal guide and is fastened on the lower part of the vertical fixed side guide. In case of a system with two or more leaves, this invention uses a ropes' central end component, tension adjusters and a ropes' run component.

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.

The present invention relates to a kit (3) for a frame, in particular for a frame of an insect protective device, with a first preassembled frame unit (1) and a second preassembled frame unit (2), wherein the two frame units (1, 2) in each case have a first free profile strip (1.1, 2.1), a second free profile strip (1.2, 2.2), and a connecting device (1.3, 2.3) having at least one further profile strip (1.3a, 1.3b, 2.3a, 2.3b). The invention also relates to profile connectors (5) for such a kit (3).

An insect net with emergency deployment structured to be retrofit onto the roof of the cab of the typical construction or agricultural equipment vehicle. The system includes a cylindrical insect net that may be compressed into a closed deployment box positioned on the underside of the vehicle cab roof. A deployment cord is positioned adjacent the operator where it may be readily accessed and pulled to open the doors of the deployment box to allow the cylindrical net to drop (under the influence of a ring of small weights) to surround the operator within the cab. The system is structured to be re-used by replacing the cylindrical net back into the deployment box and refitting the deployment cord with pull pin to hold the deployable components within the box for subsequent use.

An extendible barricade including a housing having a first panel located within the housing that is extendable from the housing, a second panel located within the housing that is extendible from the housing, wherein the housing is releasably attached to an overhead door by means of an attachment assembly. Furthermore, an associated method is also provided.

The present invention relates to a frame comprising at least two first frame struts (1.1, 1.2) and at least two second frame struts (2.1, 2.2), wherein⋅the two first frame struts (1.1, 1.2) and/or the two second frame struts (2.1, 2.2) are of invariable length, ⋅the first frame struts (1.1, 1.2) are connected at their ends in each case to a second frame strut (2.1, 2.2) and the second frame struts (2.1, 2.2) are connected at their ends in each case to a first frame strut (1.1, 1.2), and —the first frame struts (1.1, 1.2) and the second frame struts (2.1, 2.2) are arranged at a right angle with respect to one another in a frame plane in an assembled position.

A porch screen assembly for inhibiting insects from entering a porch includes a track that is mountable to an exterior of a porch has the track extending over an opening in the porch. A plurality of rollers each rollably engages the track and a plurality of hangers is each engaged to a respective one of the rollers. A plurality of curtains is each suspended from respective ones of the plurality of hangers thereby facilitating each of the curtains to be aligned with the opening in the porch. A plurality of weights is each coupled to a respective one of the curtains to inhibit the curtains from being blown about by the wind.

The present invention relates to a frame for an insect protection device for use with a building opening, comprising at least two vertical frame struts (1.1, 1.2), at least two horizontal frame struts (2.1, 2.2), and profile connectors (5.1, 5.2, 6.1, 6.2) in each case comprising at least one first connecting arm (7) and one second connecting arm (8), characterised in that each profile connector (5.1, 5.2, 6.1, 6.2) has a rotational joint (11) between the connecting arms (7, 8) having at least one axis of rotation (9, 10), such that in an initial position the vertical frame struts (1.1, 1.2) and the horizontal frame struts (2.1, 2.2) are oriented parallel to one another and that, by pivoting the frame struts (1.1, 1.2, 2.1, 2.2) relative to one another about the axes of rotation (9, 10) of the rotational joints (11) of the profile connectors (5.1, 5.2, 6.1, 6.2) connecting together two respective frame struts, the frame is able to be transferred into an assembly position in which the horizontal frame struts (2.1, 2.2) and the vertical frame struts (1.1, 1.2) are arranged in a frame plane at a right angle to one another.
