  • Patent number: 8453708
    Abstract: In order to facilitate mounting of a roller blind one end of the roller blind tube is fitted with a spring-loaded insert (M). To prevent this from being pushed back a grub screw may be used, but it requires tools and precise alignment. According to the invention a releasable pawl-and-ratchet structure (2, 4) is provided in the end plug (1). The release is obtained by rotating the holder (5) of the pawls (2), whereby they are directed into axial grooves (3 or 3?).

  • Patent number: 6615897
    Abstract: An apparatus for winding a spring on a shaft, such as for counterbalancing a roll-up door, includes a housing that carries a transmission which is positionable over the shaft. The transmission is configured to be coupled via a connector to one end of the spring, while the other end of the spring is fixed to the shaft. Rotation of the transmission results in a turning of the connector and a winding and/or elongation of the spring.

  • Patent number: 6079475
    Abstract: A security screen with a main frame having radial sections which interconnect with radial sections of a subframe when the screen is closed to strengthen the screen and increase its resistance to displacement due to sustained or impact loads. Brackets attached to the radial sections of the main frame have pins aligned to fit into holes in the radial sections of the subframe when the screen is closed. The brackets and pins serve to prevent the radial section of the main frame from bending inward under a force applied to the screen cloth by effectively combining the strength and rigidity of the main frame and subframe. Thus, the force required to displace the screen cloth a given distance is increased. The increase in strength and rigidity is accomplished without increasing the dimensions of the screen or its supporting structure. Also, the brackets serve to inhibit the security screen from being pried open. Other means to interconnect sections of the main frame and subframe are disclosed.

  • Patent number: 5915448
    Abstract: A curtain bottom tensioning assembly comprised primarily of a resilient member extending across the bottom of the door. The resilient member is directly or indirectly coupled to a guide extension extending beyond the leading edge of the door and engaging vertical guide members to guide the door in a vertical plane. The guide extensions also engage the vertical guide members to restrict the guide extensions from moving horizontally toward the curtain. The coupling between these horizontally restricted guide extensions and the resilient member places a tension on the resilient member. The resilient member is thus stretched across the bottom of the door or curtain, and serves as a bottom bar that also substantially conforms to or deflects around an obstruction, thus preventing or minimizing damage to the door, the bottom bar and the obstruction.
