  • Patent number: 6725620
    Abstract: A sealing mold arrangement includes at least an elongated mold strip adapted for mounting to an attachment corner edge of a panel frame such as a door and window frame. The elongated mold strip has an elongated first and second attachment surfaces and an alignment corner edge formed at a common line-edge where the first attachment surface meets the second attachment surface. Each of the first and second attachment surfaces has a longitudinally extended positioning guider sharp edge, a longitudinal attachment groove transversally extended from the positioning guider sharp edge towards an inner portion of the respective first and second attachment surfaces, and an edge gap surface transversally and inclinedly extended from the positioning guider sharp edge to the distal side edge of the respective first and second attachment surface to form an edge gap.

  • Patent number: 6401790
    Abstract: A magnetic dual glasses window structure includes a window blind, provided between two panes of glass, including tilt cords for supporting a plurality of slats and an operating system which includes a shaft attached to the tilt cords and a magnetic actuating device. The magnetic actuating device includes an actuating cord movably and encirclingly attaching to two end portions of the shaft, a pair of resilient elements attached to the actuating cord respectively for applying an urging force against the actuating cord, a magnetic seat connecting between the two resilient elements and positioned adjacent an inner surface of one of the panes of glass, and a magnetic slider positioned adjacent an outer surface of the pane of glass for magnetically driving the magnetic seat to move. Therefore, by sliding the magnetic slider, the actuating cord drives the shaft to rotate for controlling the tilt angle of each of the slats.
