Definitions

  • This invention relates to an improved control mechanism for a window covering. More particularly, this invention relates to an improved control mechanism for controlling the position of control cords in a window covering. Background of the Invention
  • Conventional window coverings come in a variety of styles including Roman shades, Venetian blinds, and cellular shades.
  • the light blocking elements of these window coverings are suspended from a headrail by one or more control cords.
  • These control cords when retracted or extended, raise or lower the portions of the window covering to which they are connected.
  • a control cord is typically secured to a lower portion of a continuous panel that covers the window space. By pulling on the cord, the lower portion of the panel is raised to open the window covering.
  • a control mechanism is typically included with the headrail that enables the user to controllably adjust the opening and closing of the window covering. Examples of such control mechanisms include cord locks, rotatable drums, and the like.
  • the present invention is directed to a novel control mechanism for a window covering for controlling the opening and closing of the window covering.
  • the present invention relates to a control mechanism for a window covering.
  • the window covering can take many forms, but will generally include a headrail, and a light blocking element comprising a plurality of openable rows suspended from the headrail by one or more control cords.
  • Examples of such window coverings include a Roman style shade such as disclosed in co-pending application serial no. 10/427,829, and a Venetian blind such as disclosed in patent application serial no. 10/413,200, which was issued as U.S. Patent No. 6,792,996.
  • the disclosures of each of co-pending application serial no. 10/427,829, and U.S. Patent No. 6,792,996 are hereby incorporated by reference.
  • the control mechanism of the present invention includes a frame which is mountable within a support structure, such as the headrail.
  • the frame includes a first end and a second end, as well as a first abutment stop and a second abutment stop.
  • the first abutment stop is located closer to the first end of the frame than the second abutment stop and the second abutment stop is closer to the second end of the frame than the first abutment stop.
  • a sliding module is also included in the control mechanism.
  • the sliding module is secured with a control cord of the window covering such that the movement of the control cord is synchronous with the movement of the sliding module.
  • the sliding module and the control cord move together as a unit.
  • the sliding module is in moveable engagement with the first surface of the frame and is moveable between a first position and a second position.
  • the movement of the sliding module is also biased toward the first end of the frame.
  • the portion of the control cord exiting the control mechanism at the first end of the frame may be connected to the suspended light blocking elements such that the weight of the light blocking elements pull on the cord, thus biasing the cord and sliding module towards the first end.
  • the first abutment stop limits or arrests the movement of the sliding module towards the first end of the frame.
  • the first abutment stop limits or arrests the movement of the sliding movement towards the first end of the frame when the sliding module reaches the first position.
  • the second abutment stop also limits or arrests the movement of the sliding module toward the first end.
  • the limiting or arresting of the movement towards the first end by the second abutment stop is effected when the sliding module is in the second position.
  • the particular window covering with which the control mechanism may be used can include several different forms.
  • the light blocking element is comprised of a plurality of rows of panels.
  • the panels are narrowed by raising the control cords secured to the lower longitudinal portion of each panel such that the lower longitudinal portion is raised relative to the upper longitudinal portion, and thereby narrowing the rows to create gaps therebetween.
  • the window covering includes a plurality of rows formed of slats.
  • a control cord is secured to a longitudinal portion of each slat at a position distal of the proximal edge of the slat.
  • the control mechanism may also include a further feature.
  • the frame in which the sliding module is mounted may also be designed to be extendable. For example, the lateral end at one side of the head rail where the control cord exits can be extended by the user to fit within the available space of the window frame. An additional length of the control cord may be included so as to allow the adjustment of the frame length without affecting the portion of the control cord mounted with the shade rows.
