Patent number: 6732018Abstract: This invention relates to a retractable and extendable awning and control system for automatically extending and retracting the awning. A front of an awning fabric is attached to a front bar, movably mounted on a wall of a building by retractable arms. A rear of the fabric is unrolled from a roll when the arms move the front bar away from the wall. The awning also features a weather sensor unit on its front bar in wireless communication with an indoor control unit. The weather sensor unit can detect excessive wind, mechanical shocks, sunlight, and rain. In addition, each support bracket on the awning has a screw spindle for adjusting an angle of extension of the awning from the wall with a resilient inner bushing that cushions mechanical shocks to the awning. Adhesive can also be introduced into arm ends after assembly of the arms.Type: GrantFiled: November 18, 2002Date of Patent: May 4, 2004Assignee: Turnils ABInventor: Anne J. Osinga

Publication number: 20030085004Abstract: A method of manufacturing a control cord for use in a covering for architectural openings includes the steps of providing spools of high tensile strength and low abrasion characteristic yarns, tensioning the yarns and winding the yarns under tension on bobbins, placing the bobbins in a braiding apparatus and making an eight-carrier braid from the yarns on the bobbins, and passing the braided cord through a treatment apparatus where a urethane coating is applied to the yarns and heat cured.Type: ApplicationFiled: September 26, 2002Publication date: May 8, 2003Applicant: Turnils ABInventors: Kenneth W. Witherell, Klas Ture Ivarsson

Patent number: 6484069Abstract: This invention relates to a retractable and extendable awning and a control system for automatically extending and retracting the awning. In a retractable fabric awning a front of the awning fabric is attached to a movable front bar, movably mounted at the wall of a building by retractable arms. The rear of the fabric is unrolled from a roll of the fabric on the building wall when the arms move the front bar away from the building. The awning features a weather sensor unit on its front bar. The weather sensor unit can detect excessive wind and mechanical shocks and also sunlight and rain. The sensor is in wireless (via radio frequency) communication with an indoor control unit which can automatically retract the front bar during windy, rainy and/or low sunlight conditions and extend the front bar during calm and sunny conditions.Type: GrantFiled: January 31, 2001Date of Patent: November 19, 2002Assignee: Turnils ABInventor: Anne J.
