Definitions

  • This invention relates to an improved window covering. More particularly, this invention relates to an improved window covering having the general appearance of a Roman shade but having the ability to provide openings at different intervals.
  • a Roman shade One popular type of window covering is known as a Roman shade.
  • This type of shade consists of a fabric material attached along its top edge to a head rail and gathered at spaced intervals to provide a series of soft folds across the face of the fabric. Consequently, the typical Roman shade has a cascaded or softly pleated appearance.
  • Such Roman shades are constructed so that when they are raised, they gather from the bottom in generally horizontal folds or pleats until the entire shade resides near the top of the window covering. In some versions, the top of the window covering may also be lowered.
  • the shades are operated by pulling on various lines which are used in conjunction with guides attached to the shade.
  • a common method for making a Roman shade is to sew at least two sets of rings or connectors along vertical lines down the back of the fabric material such as is shown in U.S. Pat. No. 1,321,800.
  • a lift cord passes from the head rail through each set of rings and may either be fastened to the bottom edge of the fabric or loop around the bottom edge of the fabric up the front face of the fabric and return to the head rail.
  • each set of connectors is both sewn to the fabric and attached to a cord at spaced apart intervals along the cord. The interval between spacers on each cord may be equal to or less than the distance between the points at which the spacers are attached to the back of the fabric.
  • One drawback to the typical Roman shade is that there is no way to create openings in the overall face of the window covering if one wishes to permit light into a room, such as found in Venetian blinds by tilting the blind slats, without having to raise the bottom, or lower the top of the entire window covering, which undesirably results in a substantial loss of privacy. Therefore, it is desired to provide the ability to, similar to a Venetian blind, open gaps in the shade to allow light to pass, yet maintain a relatively high degree of privacy by not requiring the shade to be raised or lowered.
  • the present invention also overcomes the shortcoming of the prior art by keeping ladder or other raising and adjustment mechanisms from view when the shade is closed.
  • the present invention relates to a decorative covering suitable for use as a window shade.
  • the decorative covering comprises a head rail with at least one securement member and at least a first opening member.
  • the decorative covering also includes rows that are suspended from the head rail, and which are typically hung over a window as a shade.
  • the window covering preferably includes a plurality of securement members and a plurality of opening members suspended from the head rail.
  • the securement members and opening members can take several forms, such as cords, narrow strips of material, a panel, or the like.
  • Each of the plurality of securement members is restrainedly positioned with each of the plurality of rows at a first transverse margin or longitudinal region of the individual rows.
  • Each of the rows also defines a plurality of row portions spaced in a transverse direction.
  • Each of the rows is also connected to at least one opening member at a transverse margin or longitudinal region opposite that of the transverse margin or longitudinal region to which the securement members are restrainedly positioned, and to at least one of the row portions.
  • a vertical adjustment mechanism is operatively connected to each of the opening members, which enables the opening member to be moved to open or close the spaced row portion of the rows restrainedly positioned therewith.
  • a single adjustment mechanism can be operatively connected to all the opening members, or each of a plurality of opening members can be operatively connected only to certain opening members.
  • the securement members are also operatively connected with a vertical adjustment mechanism, and are movable to open or close the plurality of rows.
  • the rows or row portions of the window covering can thereby be opened and closed through individual movement of the opening members or the securement member or a combination of both.
  • the transverse margins or longitudinal portions of the rows are brought closer together to collapse the rows or are urged apart to extend the rows.
  • the opening member is secured to the lower edge of the rows, when the opening member is retracted, the lower edge of each row is raised relative to the upper edge and drawn up behind the front of the row such that openings created in the face of the window covering permit light to pass.
  • Extending the opening member through use of the vertical adjustment mechanism causes the lower edge of each row with which it is connected to lower relative to the upper edge and thereby close the gaps in the face of the window covering.
  • the securement member mechanism may also be extended or retracted through use of a vertical adjustment mechanism such as described above.
  • a vertical adjustment mechanism such as described above.
  • openings in the decorative covering can be controlled by extending and retracting the securement member as well.
  • the securement member can lower the upper edge of the rows to create gaps in the face of the decorative covering.
  • both the securement member and the opening member can be adjusted as desired.
  • either the securement member can be adjusted, or the opening member can be adjusted, or both of the securement and opening members can be adjusted to create openings in the decorative covering.
  • the opening member and the securement member are capable of individual movement.
  • Restrained positioning of the rows with the securement member can be accomplished in several manners including, but not limited to, fixedly securing with adhesive, ultrasonic welding, knitting, tying or the like, or restricting the movement of the row relative to the securement member with a stop or other like restricting member.
  • the movement of the rows can be restricted by stop mechanisms positioned on the securement member.
  • the opening member which also connects the head rail and the rows, may be similarly restrainedly positioned.
  • transverse margin or longitudinal regions to which the securement members are restrainedly positioned preferably are about either the upper and lower edges of the row, which extend across the width of the window shade.
  • the opening member is restrainedly positioned about the opposite transverse margin or longitudinal regions.
  • a rigid securement strip can be used to aid in restrainedly positioning the opening and securement members with the rows. Reinforcing strips can also be included along either or both of the opposed longitudinal regions.
  • Each of the plurality of rows may be comprised of fabric material, such as a single continuous fabric material or a plurality of fabric materials.
  • the panels may also be formed from other materials such as wooden strips or slats.
  • each of the rows includes a plurality of spaced row portions, such as a first and a second side region.
  • the first and second side regions may be of equal size, thereby forming a rectangular shape, or may be of different sizes, so as to form a tapered or substantially triangular shape
  • the rows may also include a stiffened transverse portion, such as by inclusion of a strip member with the first transverse margin, such as a lightweight plastic slat.
  • a bottom rail may also be provided and suspended from the head rail, whereby the plurality of rows are located between the head rail and the bottom rail.
  • the vertical adjustment mechanisms that are operatively connected to the various opening members and, in some embodiments the securement members may be similar to mechanisms commonly found in Venetian blind systems for adjusting the position of cords, such as a worm gear assembly fitted within the head rail and manipulable by an operatively connected wand, whereby turning the wand causes, in this case, the opening member to be retracted.
  • a cord lock assembly can also be utilized with the opening member to raise and lower the opening member.
  • a power driven or remotely controlled vertical adjustment mechanism can also be utilized to retract or extend the opening member.
  • each of the rows defines a plurality of row portions spaced in a transverse direction.
  • each of the plurality of opening members is capable of substantially individually raising or lowering the row portion or row portions to which it is restrainedly position.
  • a particular row may include two row portions, such as including the edges of the row.
  • An opening member is secured to each of these row portions. By raising one of the opening members, the row portion with which it is secured is opened substantially independent of the other row portion. In other words, one side of the row is raised, and the other side is not.
  • each of the rows has a substantially triangular or tapered shape, thereby, defining a major edge portion and a minor edge portion.
  • the direction or orientation of the taper alternate from row to row.
  • the overall window covering created from the combination of similarly sized and shaped triangular rows is rectangular.
  • a pair of opening members are provided.
  • One of the cords extends down one side of the covering and is restrainedly positioned with every other row on a longitudinal portion about the less tapered or broader side region of the row. As mentioned, this less tapered or broader region defines a major edge portion of a row, and the narrower or more tapered side region of the rows defines a minor edge portion.
  • the other opening member cord is positioned down the opposite side and is restrainedly positioned with the other rows about their respective major edge portions.
  • the alternating rows define two sets of rows, namely, those rows facing in one direction are considered a first set of rows and those facing in the opposite direction are considered a second set of rows.
  • Each set of rows may be individually opened or both sets of rows may be opened.
  • the decorative covering provides a unique appearance that is unlike the window covering known in the art, which are typically parallel rows. Instead, the tapered or generally triangularly shaped rows, when raised, form a generally criss-crossing pattern.
