Description
- This application is a continuation-in-part of U.S. patent application Ser. No. 11/082,385, filed on Mar. 17, 2005.
- 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, and which is extendable to accommodate a variety of widths of window spaces.
- Conventional window coverings come in a variety of styles including Roman shades, Venetian blinds, and cellular shades. Typically, 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. For example, with a Roman shade, 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 is particularly suited to be adjustable to accommodate window spaces of differing widths.
- 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 Ser. No. 10/427,829, and a Venetian blind such as disclosed in patent application Ser. No. 10/413,200, which was issued as U.S. Pat. No. 6,792,996. The disclosures of each of co-pending application Ser. No. 10/427,829, and U.S. Pat. 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. In other words, 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. For example, 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. In particular, 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. However, 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.
- As discussed, the particular window covering with which the control mechanism may be used can include several different forms. For example, in the Roman style shade of co-pending patent application Ser. No. 10/427,829, 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. In the Venetian type blind of U.S. Pat. No. 6,792,996, 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. By raising the control cord, the slats are pivoted to open.
- 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.

Shown in the drawings and described hereinbelow in detail are preferred embodiments of the invention. It is to be understood, however, that the present disclosure is an exemplification of the principles of the invention and does not limit the invention to the illustrated embodiments.
- An example of a window covering with which the control mechanism of the present invention is suitable is shown in
FIGS. 1 and 2 . As shown, window covering 100 includes aheadrail 102, a plurality ofrows 104, and acontrol cord 106 that is secured to lowerlongitudinal portions 108 of therows 104. Thecontrol cord 106 extends through anopening 110 in theheadrail 102, and through a control mechanism, which is discussed in greater detail below. The plurality ofrows 104 are suspended from theheadrail 102 by thecontrol cord 106 which is suspended from theheadrail 102 through hole 105. The plurality ofrows 104 are further suspended from theheadrail 102 by asecurement cord 112. - The particular example of an embodiment of a window covering with which the control mechanism of the present invention is suitable for use shown here is disclosed in co-pending application Ser. No. 10/427,829, which as discussed above is incorporated by reference. The
control cord 106 is an opening member, which is secured to the lowerlongitudinal portions 108 of the rows. Thecontrol cord 106 may be secured to the lowerlongitudinal portion 108 through any means known in the art, but it is preferred that the lowerlongitudinal portion 108 include ananchor member 109 secured therewith. Thecontrol cord 106 includes a plurality ofloops 111 through which theanchor member 109 is guided. The narrowing of the rows of the window covering is accomplished by decreasing the distance between the upper and lower longitudinal portions of the rows by raising the openingmember control cord 106. - Referring to
FIGS. 3, 3A and 4, an embodiment of the control mechanism is shown. Thecontrol mechanism 200 is shown in a first position. Thecontrol mechanism 200 includes aframe 202 which is mounted in the headrail (not shown). Thecontrol mechanism 200 may be permanently mounted or replaceably mounted in the headrail. Replaceable control mechanisms enable a person to replace broken or otherwise defective control mechanisms, or to exchange a control mechanism for a particular type of window covering with a different control mechanism. Theframe 202 includes afirst end 206 and asecond end 208, as well as a first abutment stop, such aspinch roller 210 and a second abutment stop, such asarm member 212. Also included near thefirst end 206 is asecond pinch roller 214. - A sliding
module 216 is secured with acontrol cord 218 of the window covering. In this embodiment, aresilient latch member 220 is utilized to secure thecord 218 with the slidingmodule 216, however, any method of securing thecord 218 with the slidingmodule 216 can be used. In any case, the movement of thecontrol cord 218 is intended to be synchronous with the movement of the slidingmodule 216. In other words, the slidingmodule 216 and thecontrol cord 218 preferably move together as a unit. - Some of the details of the sliding module are explained with reference to
FIG. 3A and 3B . The slidingmodule 216 includesrail members 217, a pair ofcatches 219, and atrack 224. The pair ofcatches 219 are engaged with the latch member 220 (FIG. 3 ) and secure thelatch member 220 to the slidingmodule 216. The pair ofrail members 217, when the slidingmodule 216 is engaged with theframe 202 axially guide the sliding module along theframe 202. Thetrack 224 is suitable for guiding the movement of thearm member 212, which is pivotally secured at afixed end 223, and includes a roundeddistal end 226. In this embodiment, thetrack 224 is formed integrally with the slidingmodule 216. However, it is possible that the track could be formed on theframe 202 itself. - The sliding
module 216 is in sliding engagement with thefirst surface 222 of theframe 202 and is moveable between the first position shown inFIG. 3 and the second position shown inFIG. 4 . The slidingmodule 216, if not otherwise engaged, is biased to move towards thefirst end 206 of theframe 202. In this example, thecontrol cord 218 is connected to the various rows of a window covering as described above such that the weight of the rows pulls on thecord 218 and urges thecord 218 and slidingmodule 216 towards thefirst end 206 until it reaches the first position, such as shown inFIG. 3 . In this first position, the movement of the slidingmodule 216 towards thefirst end 206 is limited or arrested by the interaction ofpinch roller 210 andpinch roller 214.Cord 218 is further secured betweenpinch rollers module 216 is in this first position, thecontrol cord 218 is extended such that the various light blocking elements, such as the plurality ofrows 104 inFIGS. 1 and 2 , are closed. - By exerting a pulling force as indicated by force arrow F1 on the
control cord 218, the sliding module is urged away from thefirst end 206 of theframe 202 and towards thesecond end 208 such as shown inFIG. 4 . By moving the slidingmodule 216 towards thesecond end 208, the control cord raises the various light blocking elements such that they open to permit light to pass through the window covering. As the pulling force indicated by force arrow F1 is released, the slidingmodule 216 again moves toward thefirst end 206. However, rather than moving back to thefirst end 206, the movement of the sliding module is arrested by a second abutment stop, such asarm member 212. In particular, the roundeddistal end 226 engages ahub 228. Thus, thecontrol module 200 is held in the second position such that the various light blocking elements of the window covering are maintained in an open position. - A more detailed explanation of the interaction between the sliding
module 216 and thearm member 212 as the slidingmodule 216 moves from the first position to the second position and back to the first position is explained with reference toFIGS. 5 through 8 . - Shown in
FIG. 5 is a bottom partial view of the slidingmodule 216 and thepivotal arm member 212 of the frame having a roundeddistal end 226 and afixed end 223 when the slidingmodule 216 is in the first position. Referring toFIG. 6 , when a force such as pulling force indicated by force arrow F1 is exerted on cord 218 (FIG. 4 ) the sliding module moves towards the second end, such as indicated by direction arrow A. The roundeddistal end 226 ofarm member 212 is guided along thetrack 224 until it reaches a firstconcave portion 230 oftrack 224. Thearm member 212 pivots slightly as thedistal end 226 is guided along the firstconcave portion 230 such thatdistal end 226 is at least partially aligned withhub 228. - Referring to
FIG. 7 , as the pulling force is released, the slidingmodule 216, which as discussed is biased to move towards the first end of the frame, moves as indicated by direction arrow B. Roundeddistal end 226 is then preferably with theconcave portion 232 ofhub 228, and thereby limits or arrests the movement of the slidingmodule 216 towards the first end. As discussed, as thearm member 212 is guided along the firstconcave portion 230 oftrack 224, it pivots such than when the pulling force is released, the roundeddistal end 226 is at least partially aligned with theconcave portion 232 ofhub 228. Thus, when as the slidingmodule 216 moves towards the first end, the roundeddistal end 226 is captured within theconcave portion 232 ofhub 228. As discussed above, when the sliding module is in this second position, the light blocking elements of the window covering connected to the control cord are maintained in an open position. - To release the sliding
module 216 from thearm member 212 so the sliding module can be moved from the second position to the first position, and more particularly in this embodiment, to disengage roundeddistal end 226 fromhub 228, a user again exerts a pulling force oncord 218. Accordingly, the sliding module again moves as indicated by direction arrow A towards the second end of the frame. Referring toFIG. 8 , acusp portion 234 of thetrack 224 is positioned relative to theconcave portion 232 ofhub 228 such that the roundeddistal end 226 of thearm member 212 is guided into a secondconcave portion 236 of thetrack 224 and so the roundeddistal end 226 clearshub 228. As the slidingmodule 216 is again moved towards the first position, the roundeddistal end 226 ofarm member 212 is guided alongtrack 224 and returns to the first position as shown inFIG. 5 . - Thus far the control mechanism has been described as designed for controlling the raising and lowering of a single control cord. In some situations, the control mechanism may be provided in a headrail as a unit including a pair of sliding modules, such as shown in
FIGS. 9 and 10 . Acontrol mechanism 300 is mounted withinheadrail 301 and comprises asingle frame 302 that includes a pair of slidingmodules 316 and 317. Of the slidingmodules 316 and 317 are independently operable to control the raising or lowering of the cord secured thereto. This cord can be any positioning cord in a window covering. For example, reference is made to the window covering disclosed in co-pending application Ser. No. 10/914,579 filed on Aug. 9, 2004, and which is hereby incorporated by reference. In this embodiment a control cord, such as openingmember 318, is secured with the plurality ofrows 304 at lowerlongitudinal regions 320. Openingmember 318 is also secured with sliding module 316. Asecurement member 319 is secured with the plurality ofrows 304 at upperlongitudinal regions 322, and is also secured with slidingmodule 317. The plurality ofrows 304 may therefore be narrowed by either loweringsecurement member 319, by raisingopening member 318, or some combination of the two that results in the narrowing of the rows. - Another embodiment of a window covering with which the control mechanism of the present invention may be used is shown in
FIG. 11 , which depicts a row of a Venetian blind type window covering. This Venetian blind type window covering is described in detail in U.S. Pat. No. 6,792,996, which is incorporated herein by reference. The light blocking elements of the Venetian blind type window covering comprises a plurality of rows of slats, such asslat 400. The slat comprises a firstlongitudinal portion 412 at a edge portion of therow 400, and a secondlongitudinal portion 426 formed within the main portion of thepanel 410. Each of thelongitudinal portions cords control cord 402 is restrainedly positioned with thelongitudinal portion 412 by engaginganchor member 406 withcontrol cord 402 by passing theanchor member 406 through aloop 408 formed therein.Control cord 404 is operatively connected with the secondlongitudinal portion 426 by engaging afastener module 430 therewith, and engaging thefastener module 430 with ananchor member 416 throughopening 414.Control cord 404 is secured with a control module (not shown) such as discussed above. - An additional feature of the present invention is discussed below. Since many window spaces come in nonstandard widths, it is desired to provide the ability to prepare stock widths of head rails that may be adjusted to fit a window space. The present invention provides for a frame that is extendable. Referring to
FIGS. 12 and 13 , thelateral end 500 of theframe 502 at one side of thehead rail 504, such as where the control cord (not shown) exits, can be extended relative to thehead rail 504 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. - One embodiment of this feature of the present invention is discussed with reference to
FIGS. 14-17 . Acontrol mechanism 600 includes aframe 602 which is mounted in thehead rail 604. Theframe 602 defines a track including acentral portion 608 and marginal portions 610 paralleling thecentral portion 608. In this example, a single slidingmodule 612 is included. Preferably formed along the marginal portions 610 are matched series of detent members, such asslots resilient latch member 620. Referring toFIG. 16 ,latch member 620 includes apush member 622, a pair of engagingfingers tab 628. Referring toFIG. 15 , and more particularly toFIG. 15A , thetab 628 is secured withhead rail 604 withinslot 630 formed therein. The distance between the twoengaging fingers central portion 608 between the marginal portions 610. The engagingfingers detents 618 to lock the position of thecontrol mechanism 600 relative to thehead rail 604. Thelatch member 620 extends upwardly throughcentral portion 608. - To change the position of the
control mechanism 600 and extend the overall width of thehead rail 604 and theframe 602 ofcontrol mechanism 600, the user pushes downward on thepush member 622, which causes thelatch member 620 to deflect and consequently disengage the engagingfingers detents 618. The user then can slide thecontrol mechanism 600 to retract or extend theframe 602 from thehead rail 604, such as shown inFIG. 17 byarrow 632. Once the desired position of thecontrol mechanism 600 is reached, the user releases thelatch member 620. Thelatch member 620 resiliently recovers its initial position, and the engagingfingers control mechanism 600. - Another embodiment of the present invention is discussed with respect to
FIGS. 18-21 .Control mechanism 700 again includes aframe 702 which is mounted in ahead rail 704.Head rail 704 defines ahole 706. The bottom surface of the frame includes a series of regulartransversal indentations 710. Acentral portion 712 bisects the series of indentation and forms a gap. When theframe 702 is mounted within thehead rail 704, thehole 706 through the bottom surface of thehead rail 704 is aligned with thecentral portion 712. A latch member, such as screw-bolt fastener 714 passes throughcentral portion 712 and is adapted to engagehole 706. Atoothed washer 715 which is adapted to be seated withinindentations 710 is also provided as part of the latch member.Toothed washer 715 is pressed against theindentation 710 when screw-bolt fastener 714 engageshole 706, thereby fixedly securing the relative positions of theframe 702 and thehead rail 704. Releasing the screw-bolt fastener 714 disengages thetoothed washer 715 from theindentation 710 such that the relative position of theframe 702 and thehead rail 704 can be adjusted as indicated byarrow 720. - Yet another embodiment of the present invention is described with respect to
FIGS. 22-25 .Control mechanism 800 includes a frame 802 which is mounted in ahead rail 804.Head rail 804 defines a plurality of holes orslots 806. As an alternative to holes or slots as detents, indentations may be used. A latch member, such as astop rod 808, which includes acompressive spring 810, is positioned withinrecess 812 in frame 802. Thedistal end 814 ofstop rod 808 is adapted to engage holes orslots 806.Spring 810, which abutsflange 815 ofrecess 812, is biased to urgestop rod 808 downward to engage a hole orslot 806. To adjust the position of the frame 802 ofcontrol mechanism 800 relative to thehead rail 804, the user pulls up thestop rod 808 as indicated by arrow 816, and disengagesdistal end 814 from hole orslot 806. The relative position of thehead rail 804 and the frame 802 can then be adjusted as indicated by arrow 818. Once the desired position of thecontrol mechanism 800 is reached, the user releases thestop rod 808 such thatspring 810 urges thestop rod 808 to engage another of the holes orslot 806. - As an alternative, a plurality of latch members and a single detent member can be utilized. For example, a series of stop rods may be provided that engage a single hole or slot. As another alternative, a combination of a plurality of latch member and a plurality of detent members may be used.
- With any of the embodiments, in order to install a window covering, the width of the window space is measured. In any of the manners discussed above, the overall width of the head rail and the portion of the frame extending from the side edge of the head rail is made to fit within the width of the particular window space. The fit need not be exact, but can be approximated by the spacing of the latch members, detent members, or both. The head rail is then mounted within the window space.
- The foregoing descriptions are to be taken as illustrative, but not limiting. Still other variants within the spirit and scope of the present invention will readily present themselves to those skilled in the art.
