Patent number: 10428580Abstract: A roller blind system, comprising a roller blind having a roller shaft through which a central rod extends and to which a flexible sheet member is attached. The roller blind is provided with two bracket connectors arranged for releasable coupling to mounting brackets. The roller blind is spring operated and comprises a tension spring fixedly connected to the central rod and to the roller shaft and a tension adjusting mechanism for adjusting the tension of the tension spring. The tension adjusting mechanism comprises an adjusting wheel and an adjusting spring for adjusting the rotational position of the central rod, a first bush part arranged on the adjusting wheel for pushing the adjusting spring in a relaxed configuration and a second bush part connected to the central rod for pushing the adjusting spring in a tightened configuration.Type: GrantFiled: October 27, 2016Date of Patent: October 1, 2019Assignee: Coulisse B.V.Inventors: Ruben Hubert Jan de Vries, Bastiaan Franciscus Klein Tuente, Thomas Johan Maria Ter Haar

Patent number: 9452663Abstract: The present invention discloses a shading device includes a screen, a shaft portion having a lock portion to be locked, a biasing mechanism, a locking member that is engaged at a lock position with the lock portion, and a housing in which the end portion of the shaft portion is inserted. The housing has a sliding guide portion in which the locking member is slid. The sliding guide portion is capable of guiding the locking member in a direction passing through the lock position and a lock release position, and has a lock position engagement portion for stopping the locking member from sliding at the lock position. The locking member includes a slide engagement portion that engages with the lock position engagement portion at the lock position and an operating portion that can be flexed to release the slide engagement portion from the lock position engagement portion.Type: GrantFiled: July 2, 2015Date of Patent: September 27, 2016Assignees: HAYASHI TELEMPU Co., Ltd., NIFCO INC.Inventors: Keisuke Watanabe, Toshiya Nishiura, Yoshihiro Tsuchimoto, Naofumi Yagame

Patent number: 7082983Abstract: A window shade component group which includes a window shade supporting windup shaft with bearing devices for rotatably supporting opposite ends of the windup shaft. At least one of the bearing devices is provided with a blocking device, which is effective for maintaining a spring drive of the windup shaft in the wound position after assembly of the windup shaft. Following installation of the window shade component group in a motor vehicle or appropriate housing, the blocking device is releasable as an incident to actuation of the windup shaft.Type: GrantFiled: December 27, 2002Date of Patent: August 1, 2006Assignee: BOS GmbH & Co. KGInventors: Abdoul Coulibaly, Bouaziz Belibel, Christoph Binder
