Title: Operating system for collapsible covering for architectural openings

Description:
CROSS REFERENCE TO RELATED APPLICATION  
      The present application claims the benefit under 35 U.S.C. § 119(e) to U.S. Provisional Patent Application No. 60/737,166 (“the &#39;166 application”), which was filed on Nov. 16, 2005, and entitled Operating System for Collapsible Covering for Architectural Openings.” The &#39;166 application is incorporated by reference into the present application in its entirety. 
    
    
     BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      The present invention relates generally to operating systems for coverings for architectural openings and more specifically to an operating system for a vertically movable collapsible shade which is counterbalanced so as to be removably positionable at any location between fully extended and retracted positions. The system is modular and can be manually or electrically operated.  
      2. Description of the Relevant Art  
      Coverings for architectural openings have been in use for many years with some coverings being static and typically more decorative while others are retractable so as to perform both an aesthetic and functional role. Retractable coverings can be vertically movable or horizontally movable between extended and retracted positions relative to the architectural opening. In the case of vertically movable retractable coverings, the weight of the shade becomes a factor and, accordingly, counterbalanced systems have been developed so that the shade is easily movable between extended and retracted positions and will remain in any selected position therebetween. Motor driven coverings have also been developed and are particularly useful with remote architectural openings which are not easily accessible and therefore manual operation of the covering becomes a problem.  
      Improvements in operating systems for retractable coverings for architectural openings are continually being made and it is to provide such an improvement that the present invention has been developed.  
     SUMMARY OF THE INVENTION  
      The present invention relates to a control system for a vertically movable, collapsible covering for architectural openings. The system includes a top rail connected to the framework around the architectural opening with mounting brackets, a bottom rail containing the operative components of the operating system, a collapsible shade or fabric extending between the top and bottom rails, and a plurality of lift cords anchored at their upper ends to the top rail and to the operating system within the bottom rail at their lower ends.  
      The operating system includes a wrap spool for each lift cord and a system for rotating the wrap spools in a predetermined direction so as to cause the lift cords to be wrapped on the wrap spools when the covering is retracted. The spools can be rotated either by coil springs or by an electric motor with the coil springs or motor being modular units and interchangeable. The coil springs or the electric motor provide assistance in counterbalancing the covering so that it can be removably positioned at any location between fully extended and retracted positions. A plurality of guide pins are also provided in the bottom rail and form a part of the operating system with the lift cords being passed in selected circuitous paths around the guide pins to establish selected frictional resistance to movement of the shade so that the counterbalancing of the shade can be regulated depending upon the size and, therefore, the weight of the shade.  
      While the operating system could be used with any vertically movable shade, it is described in connection with a collapsible fabric that extends between the top rail and the bottom rail and extends across the architectural opening when the covering is extended but can be retracted into a neat stack adjacent the top rail when the covering is fully retracted.  
      Other aspects, features and details of the present invention can be more completely understood by reference to the following detailed description of a preferred embodiment, taken in conjunction with the drawings and from the appended claims.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
      A retractable shade or cover  40  incorporating the operating system of the present invention is show in  FIG. 1  to include a top rail  42  supported by mounting brackets  44 , a bottom rail  46  housing the operating system of the invention, and a collapsible fabric  48  extending between the top and bottom rails. While the collapsible fabric could be any one of numerous designs, for purposes of the present disclosure, it is probably seen best in  FIGS. 1, 5B ,  7 , and  8  to include a flexible support structure  50  of sheer fabric, support cords or the like suspended from the top rail  42  and to which is attached at vertically spaced locations along horizontal lines of attachment a plurality of semi-rigid transversely arcuate vanes  52 . The semi-rigid vanes are alternately attached to the support structure on opposite faces of the support structure and along a top edge of the vane so as to hang freely downwardly from their connection to the support structure on opposite sides of the support structure.  FIGS. 1 and 7  show the collapsible fabric  48  extended while  FIGS. 2 and 8  show the fabric collapsed in adjacent relationship with the top rail  42  of the covering. In the retracted position, the support structure is gathered adjacent the top rail in a manner to be described later and the vanes are nested relative to each other on front and back sides of the bottom rail  46 . A fabric of the type herein disclosed is described in more detail in copending U.S. application Ser. No. 10/581,872, filed Jun. 5, 2006, which application is the Section 371(c) filing of PCT International Application No. PCT/US2004/043043, which is of common ownership with the present application and herein incorporated by reference. A plurality of lift cords  54  extend from the top rail to the bottom rail and are utilized to raise the bottom rail relative to the top rail when retracting the covering. The top end of each lift cord is attached to the top rail while the bottom end is attached to the operating system as will be described in detail hereafter.  
      The top rail  42  is probably best seen in  FIGS. 7, 8 ,  11  and  12  to comprise an extruded body having a downwardly concave arcuate top wall  56 , a downwardly convex arcuate bottom wall  58 , a forwardly opening slot  60  in a front wall adjacent the top of the top rail, a downwardly opening slot  62  in the bottom wall, a rearwardly opening slot  64  between a C-shaped groove  66  at the top of the slot and an upwardly projecting lip  68  at the bottom. The slots and grooves in the top rail serve a function to be described hereafter and the top rail is adapted to be mounted on the mounting brackets  44 . End caps  69  are inserted into the open ends of the top rail.  
      The slot  64  on the rear side of the top rail is adapted to receive a removable component  70  of each mounting bracket  44  so that the top rail can be suspended from the mounting bracket in a forwardly projecting position. Of course, any desired number of mounting brackets can be utilized and connected to the top rail at horizontally spaced locations as shown for example in  FIGS. 1 and 5 B. The mounting bracket, as best seen in  FIGS. 11-14 , has a base  72  and the removable component  70 . The base is generally L-shaped having a vertical leg  74  with openings  76  for receipt of fasteners (not shown) to secure the base to a vertical surface (not shown) of the framework around an architectural opening and a forwardly projecting horizontal leg  78  defining a forwardly opening horizontal slot  80  between a top wall  82  of the horizontal leg and a pair of shoulders  84 . A cross bar  86  with a lower bevel surface  88  bridges the space between the shoulders. The top wall  82  also has openings  90  therethrough for the receipt of fasteners so the mounting bracket can be secured to a horizontal surface of a framework rather than a vertical surface.  
      The removable component  70  of the mounting bracket  44  has a vertical plate  92  along its front edge with a beaded upper edge  94  adapted to be slid into the C-shaped groove  66  of the top rail  42  with the lower edge of the plate being received behind the lip  68  of the rearwardly facing slot  64  of the top rail. In this manner, the removable component is slidably but positively secured to the top rail at any location along the length of the top rail. The removable component is made of a semi-rigid material such as a suitable plastic and includes an upper horizontal plate  96  adapted to be received in the horizontal slot  80  of the base and a flexible lower arm  98  having a bevel surface  100  adapted to engage the bevel surface  88  of the cross bar  86  in the base so that the flexible lower arm can be flexed as seen in  FIG. 12  when the removable component is inserted into or removed from the base. Once the removable component is fully inserted into the base, the bevel surface  100  of the lower arm catches behind the cross bar  86  to releasably connect the removable component to the base. Of course, to remove the removable component from the base, the lower arm is simply pulled or flexed downwardly and the removable component slid forwardly out of the slot.  
      As best seen in  FIGS. 7 and 8 , the forwardly opening slot  60  on the front wall of the top rail  42  is adapted to receive a retention bar  102  around which the support structure  50  for the fabric in the covering is wrapped. The retention bar thereby holds the support structure in the slot  60  so that the collapsible fabric is suspended from the top rail. As will be appreciated, the uppermost vane  52  on the support structure hangs forwardly and thereby blocks most of the top rail from a front view while the remainder of the fabric hangs substantially vertically beneath the top rail.  
      As best seen in  FIGS. 5B and 7 , a protective guard  104  of a rigid or semi-rigid material such as plastic is suspended from the C-shaped groove  66  in the rear wall of the top rail  42  and is notched at  106  as seen in  FIG. 5B  so as not to inhibit connection of the top rail to the mounting brackets. The protective guard is arcuate in nature and extends downwardly from the top rail so as to prevent damage to the fabric  48  when fully retracted as the fabric might otherwise engage the framework for the architectural opening, the mounting bracket or the like.  
      As mentioned previously, the lift cords  54  are provided at spaced intervals along the length of the top rail  42  and the number of lift cords are dependent upon the width of the covering and the consequent weight of the fabric. Each lift cord is anchored in the downwardly opening slot  62  of the top rail as best illustrated in  FIGS. 9 and 10 . The connection system is identical to that disclosed in detail in applicant&#39;s aforenoted copending U.S. application Ser. No. 10/581,872, filed Jun. 5, 2006, which application is the Section 371(c) filing of PCT International Application No. PCT/US2004/043043, which has previously been incorporated by reference. Pivotal lock fingers  108  are slid into the downwardly opening slot in the top rail and the fingers are adapted to be pivoted about the end  110  thereof received in the slot. A lift cord is wrapped about the pivotal end  110  when the finger extends vertically downwardly as shown in  FIG. 9  but when the finger is pivoted up into a horizontal position within the downwardly opening slot, the lift cord is pinched between the finger and a wall of the downwardly opening slot to positively anchor the lift cord. Of course, the length of the lift cord, which will ultimately determine the disposition of the covering can be easily adjusted through use of the lock fingers.  
      The bottom rail  46  includes an extrusion  112  with the extrusion being of the type described in detail in applicant&#39;s aforenoted copending U.S. application Ser. No. 10/581,872, filed Jun. 5, 2006, which application is the Section 371(c) filing of PCT International Application No. PCT/US2004/043043, which was previously incorporated by reference. The extrusion is made of a semi-rigid material which has some flexure but will yieldingly retain its primary configuration probably seen best in  FIGS. 19-22 . The extrusion includes a horizontal base  114  having upwardly convergent forward and rearward plates  116  defining an open groove  118  in the top of the extrusion and downwardly depending legs  120  with the legs having confronting concave surfaces  122  at their lower ends. A space  124  is defined between the legs for receipt of components to be described hereafter.  
      The components for the operating system of the invention are suspended from the extrusion  112  and confined within an outer cover  126  of the bottom rail as shown in  FIG. 18  that simulates two confronting vanes of the collapsible fabric. The extrusion and outer cover with end caps  128  and a handle  130  for movement of the covering constitute the bottom rail  46  or a dummy vane at the bottom of the covering. The components of the operative system suspended from the extrusion  112  within the bottom rail or dummy vane are designed to control the lift cords  54  so that the effective length of the lift cords can be shortened or lengthened depending upon the desired position of the shade. The components in the dummy vane are designed to counterbalance the weight of the covering  40  so that it can be removably positioned at any location between fully extended and retracted positions. As best seen in  FIG. 4A , the operating components suspended from the extrusion include a plurality of guide pins  132  on mounting supports  134  with the mounting supports being pivotally suspended from the depending legs  120  of the extrusion and a spring-controlled cord gathering system  136  which is mounted at or near the longitudinal center of the extrusion.  
      Looking first at the cord gathering system  136 , as best shown in  FIG. 4B , it will be seen to have two horizontally disposed wrap spools  138  which are generally cylindrical having a non-circular axial passage  140  therethrough for receipt of a complementary non-circular drive shaft  142 . The drive shaft is operatively connected to a modular spring unit  144  ( FIG. 4C ) having a constant tension spring  146  mounted so as to not only counterbalance the weight of the covering, but also to bias the drive shaft  142  in a direction that would cause the lift cords  54  to wrap around the wrap spools  138 .  
      The wrap spools  138  and drive shaft  142  are confined within a two-piece gathering system housing  148  shown in  FIG. 6  which has two arcuate chambers  150  in which the wrap spools are disposed. The chambers are also defined by vertical walls  152  having arcuate notches  154  therein for rotative support of the drive shaft. The lower edges of the housing halves  156  have connectors for releasably securing the two halves together while the upper edges have confronting flanges  158  with one flange having a plurality of projecting hooks  160  and the opposite half having complementary catches  161  so that when the upper halves are positioned in confronting engagement, the hooks  160  are received on the catches to releasably hold the halves in confronting relationship with the closed chambers  150  for rotative support of the wrap spools  138 . The upper flange  163  on each half has an outwardly directed horizontal bead  162  so that when the halves are in confronting relationship, the flange  163  can be inserted into the space  124  between the depending legs of the extrusion as possibly seen best in  FIG. 18  with the beads  162  on the flanges projecting outwardly into the confronting concave lower ends  122  of the depending legs so that the housing is slidably and releasably suspended from the extrusion  112 . As also seen in  FIG. 18  each housing half  156  has a raised finger  165  (one longer than the other) in a gap in the associated flange  163  so that, a fastener  164  can be passed through the raised fingers to draw them together whereby they engage and pinch the depending legs  120  therebetween to positively position the housing  148  on the extrusion  112  to prevent the housing from sliding along the protrusion. The housing serves as a ballast and can be positively positioned at any desired location along the length of the extrusion. The positioning of the housing thereby allows an adjustment in the covering to assure the covering will hang smoothly with the bottom rail  46  disposed horizontally.  
      As best appreciated by reference to  FIGS. 5A and 6 , the drive shaft  142  protrudes from the left end of the housing  148  and receives a connector  166  having a socket  168  configured to receive for unitary rotation the end of the drive shaft and a square stub shaft  172  projecting from its opposite end. The connector thereby rotates with the drive shaft and the square stub shaft is adapted to be received in the modular spring unit  144  so as to coil and uncoil the spring  146  depending upon the direction of rotation of the drive shaft. The coil spring unit is a conventional unit and is of the type also described in applicant&#39;s U.S. Pat. No. 7,063,122 B2, which is hereby incorporated by reference.  
      A horizontal space  170  is defined between the upper flanges  163  of the housing halves  156  when they are connected and a pair of horizontal pins  172  ( FIG. 4B ) extend between the halves so as to bridge the space between the flanges. The pins  172  are vertically aligned with one end of an associated wrap spool  138  and as will be described hereafter, a lift cord  54  is adapted to be passed around the pin  172  and downwardly onto the associated wrap spool. The pins  172  are aligned with the left end of each wrap spool and it can be seen that the main body  174  of each wrap spool is generally cylindrical except at its left end  176  where it is frustoconical in configuration defining a sloped outer surface converging to the right and into the cylindrical surface of the wrap spool. As possibly best appreciated by reference to  FIGS. 4A and 4B , as lift cord is fed to an associated spool and the spool is rotated in a wrapping direction, the cord is wrapped at a relatively large diameter and each additional wrap forces a previous wrap down the sloped frustoconical surface  176  into a smaller diameter and therefore a looser wrap on the wrap spool so that cord can be wrapped and forced to the right with each successive wrap without entanglement of the cord. Of course, when the wrap spools are rotated in an unwrapping direction, the lift cord is removed therefrom in a reverse direction.  
      Before the lift cord  54  is passed into the housing for the wrap spools, however, it is passed through the guide pin mounting support or structure  134  where the lift cord is passed in a predetermined possibly circuitous path around a predetermined number of the guide pins  132  which provide frictional resistance to sliding movement of an associated lift cord  54 . With reference to  FIGS. 4A, 4B ,  6 , and  15 , it will be seen that each mounting structure also has two halves  178  which are interconnectable in face-to-face relationship and are generally of T-shaped configuration. A plurality of guide pins  132  are anchored in one of the T-halves  178  so as to project toward the opposite T-half where it is received in a complementary recess (not seen) so that the pins  132  bridge the space between the T-halves. Connection pins  180  are positioned at each end along the top edge of the horizontal leg  182  of one T-half and these pins serve to connect the top edge of each T-half to the other. The T-shaped support structures  134  are made of a semi-rigid material such as plastic which has some flexure so even though they are secured together along their top edge, the bottom or vertical legs  184  of the T-halves can be separated for purposes of threading a lift cord through the mounting structure.  
      At one end of the horizontal leg  182  of a T-half  178  and on an outside face thereof, a generally hemispherical bead  186  is provided which is adapted to be pivotally inserted into the space  124  between the depending legs  120  of the extrusion  112  so as to be within the confronting concave lower edges  122  of the depending legs. This connection allows the T-shaped mounting support  134  to be pivoted between the positions of  FIGS. 4A and 4B  for a purpose to be described later. At the opposite end of the horizontal leg  182  of each T-shaped half is a pivotal finger  188  having a bead  190  formed near its top and a finger gripping portion  192  at its bottom. The bead at its top is also adapted to be received in the space  124  between the depending legs of the extrusion as seen in  FIG. 20  so as to project into the space between the curved confronting concave portions of the legs but by squeezing the fingers toward each other, the beads on the fingers can be removed from the space between the depending legs as seen in  FIG. 21 .  
      With reference to  FIGS. 4A and 4B , it can be seen that each lift cord  54  extends vertically through a hole  194  in the horizontal base  114  of the extrusion  112  for sliding movement therethrough. The hole and thus the lift cord is aligned with one end of a mounting structure  134  adjacent the pivotal hemispherical bead  186 . The lift cord enters the space between the T-shaped halves through an opening  196  defined between two vertically directed semi-cylindrical bodies  198  best seen in  FIG. 6  with that opening being aligned with one of the guide pins  132  formed on the T-shaped support structure. As will be appreciated from the description hereafter, any number of guide pins  132  can be provided depending upon the height and width and thus the weight of the covering  40  but a first embodiment is shown in  FIGS. 4A, 4B ,  6  and  15  wherein there are a pair of horizontally spaced guide pins on the horizontal leg  182  of the mounting structure  134  and a pair of guide pins on the vertical leg  184  of the mounting structure. The lift cord can be passed around these guide pins in various manners such as shown in  FIG. 4A  or  4 B. Obviously, the more pins the lift cord passes around the more frictional resistance there is to the sliding passage of a lift cord through the mounting structure thus giving more assistance to controlling the weight of the shade so that it can be counterbalanced and removably positioned at any location between fully extended and fully retracted positions.  
       FIG. 16  shows a second embodiment wherein there are three vertically aligned guide pins  132  in the vertical leg  184  with  FIG. 17  showing still a further embodiment where there are seven vertically aligned pins  132  in the vertical leg with each of the alternative embodiments having the two horizontally spaced guide pins  132  in the horizontal leg  182 .  
      As mentioned previously, the T-shaped mounting structures  134  are pivotally suspended from the extrusion  112  to facilitate threading of a lift cord  54  through the mounting structure. It has been found to be convenient to pivot the end of the horizontal  182  leg having the pivotal finger  188  thereon downwardly to provide adequate spacing from the extrusion so an operator can easily thread the lift cord through the T-shaped mounting structure. Once it has been threaded, it can be pivoted from the threading position of  FIG. 4B  to the operative position of  FIG. 4A  and snapped in place as described previously.  
      In operation of the covering, with the lift cords  54  threaded as illustrated in either  FIG. 4A  or  FIG. 4B , it will be appreciated that when the covering is moved from the fully retracted position of  FIG. 2  to the fully extended position of  FIG. 1 , the lift cords are caused to be unwrapped from their associated wrap spools  138  and rotation of the wrap spools condition the operatively connected coil springs  146  to maintain a bias on the wrap spools in an opposite direction. The coil springs thus have a role in supporting the shade at any position between the fully extended and retracted positions but the friction of the lift cords as they pass around the guide pins  132  further helps in supporting the shade at any location. The guide pins provide a fine tuning system for regulating the amount of support provided by the mounting system depending upon the weight of the shade which is normally determined by the height and width of the shade.  
      As mentioned previously, the extrusion  112  supports an outer plastic shield or body  126  of a configuration simulating a pair of confronting vanes of the collapsible fabric so as to form the bottom rail or dummy vane. Such an arrangement is also shown and described in detail in the afore-mentioned copending U.S. application Ser. No. 10/581,872, filed Jun. 5, 2006, which application is the Section 371(c) filing of PCT International Application No. PCT/US2004/043043. The top edge of the shield  126  has barbs  200  ( FIG. 8 ) adapted to be supported on shoulders  202  defined on the outer surface of each depending leg  120  of the extrusion  112  and the upper edges of the sides of the protective cover are inserted into a space between the flared side walls  116  of the extrusion and the depending legs  120 .  
      With reference to  FIG. 5A , the end caps  128  are of the same cross-sectional configuration as the protective cover  126  and can be inserted into the open ends of the cover. The end caps have inwardly protruding pins  204  received in the open ends of the extrusion  112  to further secure and support the protective body. The handle  130  is attached to the bottom edge of the protective cover at the longitudinal center thereof with the handle having a bottom generally circular plate-like portion  206  of a predetermined thickness for example 1/16 of an inch and two upwardly flared ears  208  between which the protective body can be inserted. Openings  210  extend through the protective body for receipt of connector pins  212  on the ears so that the handle is positively secured to the protective body and in a position to raise or lower the dummy vane  46  and thus the extrusion  112 . The thickness of the bottom plate of the handle establishes a predetermined spacing between the dummy vane and a window sill for example so that the spacing is uniform when the covering is fully extended.  
      From the above, it will be appreciated that an operating system for a retractable vertically movable covering for architectural openings has been described which reliably allows the shade to be removably positioned at any location between a fully retracted position adjacent the top rail and a fully extended position wherein the fabric extends across an architectural opening.  
      An alternative motorized embodiment of the covering is shown in  FIGS. 23-35 . As can be appreciated by reference to  FIG. 23 , the structural components of the shade are identical to that previously described with the only modification being in the fact that a solar powered motor  214  is used to operate the shade rather than being operated through the lift handle and coil springs. As will be described in more detail hereafter, the motorized embodiment of the invention utilizes solar cells for generating DC current which is delivered through appropriate circuitry to a motor for driving the drive shaft of the wrap spools in lieu of the springs of the first described embodiment.  
      With reference to  FIGS. 24 and 24 A, a conventional strip  216  of solar cells is laid either across the sill  218  ( FIG. 24A ) for the architectural opening or if there is a glass panel  220  or the like in the opening, the strip of solar cells can be attached to that panel as shown in  FIG. 24 . As possibly best seen in  FIG. 26 , the output from the strip of solar cells is fed through electrical wiring  222  into an induction housing  224  having a control circuit  226  ( FIG. 29 ). The induction housing is seen anchored to the frame for the architectural opening and includes a cradle  228  in which the dummy vane  46  can be seated. There is an induction housing  224  at both sides of the architectural opening so as to receive and cradle both ends of the dummy vane.  
      With reference to  FIG. 29 , the induction housing  224  includes the control circuit  226  for converting the DC current to AC current which is transmitted through a circuit board  230  to an AC transmitting circuit  232  which induces the AC current into a receiving circuit board  234  disposed within the dummy vane  46  at the bottom of the cover. The receiving circuit board  234  converts the AC current it receives back to DC current which is transmitted through appropriate wiring  236  ( FIG. 28 ) to battery packs  238  in opposite ends of the dummy vane. Each battery pack, as possibly best appreciated by reference to  FIGS. 34 and 35 , receives four rechargeable batteries  240  with the DC current received at each battery pack being used to recharge the batteries. The battery packs are suspended from the extrusion  112 . DC current from the battery packs is transmitted via appropriate wiring  242  to a control circuit board  244  mounted on a motor housing  244  as best viewed in  FIGS. 32 and 33 . The control circuit board is electrically connected to the motor  214  positioned within the motor housing for energizing and de-energizing the motor. The motor is held within the motor housing by a cap  250 .  
      The motor housing  246  has a mounting plate  252  which not only supports the control circuit board  244  but also rotatably supports a gear  254  forming a transmission so that the rotational speed from the output of the motor is appropriately geared down through a predetermined mechanical advantage for output through a gear shaft  256 . The gear and the motor housing are mounted in a motor mount  258  with the gear being rotatably seated in a bearing within the motor mount and drivingly engaged with the square stub shaft  172  on the connector  166  described previously. It therefore will be appreciated that solar energy absorbed by the solar cells is transmitted to the motor for selective rotation of the drive shaft which drives the wrap spools  138  in either desired direction.  
      The housing  148  for the wrap spools  138  has flexible attachment fingers  260  that releasably grip the motor mount  258  or the spring unit  144 , as the case may be, so that the system is modularized and can be converted between a manually operated system as described in connection with the first embodiment and a motorized system.  
      The handle  262  mounted on the bottom edge of the dummy vane  46  in the motorized embodiment is shown best in  FIGS. 25-27 ,  30  and  31  to again have a base  264  and a pair of upstanding ears  266  which are connected to the dummy vane with support pins  268 . The base in the motorized embodiment, however, has a raised forward edge  270  having a pair of openings  272  for receipt of a push button switch  274  and an infrared sensor  276 . Wiring from the push button switch and infrared sensor pass to the electric motor  214  as seen in  FIG. 28 . The push button switch can be depressed manually to cause the motor to run in either direction to raise or lower the covering. The infrared sensor can be used to cooperate with a remote controller that also drives the motor in one direction or the other depending upon the direction of movement desired for the covering.  
      Pursuant to the above, it will be appreciated the operating system for the collapsible covering is seen to be modularized so that it can be manually operated or motor driven either by a touch of a finger or remotely. In either event, the control system is all mounted in the dummy vane at the lower end of the covering so that no headrail is required for the covering.  
      Although the present invention has been described with a certain degree of particularity, it is understood the present disclosure has been made by way of example and changes in detail or structure may be made without departing from the spirit of the invention as defined in the appended claims.
