Definitions

  • the present invention relates generally to safety systems for coverings for architectural openings and more particularly to a system for confining lift cords used in retractable coverings for architectural openings so that they cannot form loops in which children or infants can catch a body part thereby causing injury.
  • retractable coverings for architectural openings such as windows, doors, archways and the like, have become commonplace and assume numerous variations for both functional and aesthetic purposes.
  • Such retractable coverings typically include a headrail, in which the working components for the covering are primarily confined, a bottom rail extending parallel to the headrail, and some form of shade material which might be fabric or other manipulative structure such as found in Venetian blinds for example, interconnecting the headrail and bottom rail.
  • the shade material is movable with the bottom rail between extended and retracted positions relative to the headrail.
  • the fabric or other material is extended away from the headrail or retracted toward the headrail so it can be accumulated either adjacent to or within the headrail.
  • Systems for operating such retractable coverings can assume various forms such as pull cords that hang from one or both ends of the headrail.
  • the pull cords may assume a closed loop or hang linearly.
  • the covering is operated remotely with electronics and a motor mounted within the headrail avoiding the need for such pull cords.

  • DETAILED DESCRIPTION OF THE INVENTION Referring first to FIGS. 1-4, an example of a retractable covering for an architectural opening in which the protector of the present invention would find an application is illustrated. It should be appreciated, the covering shown in FIGS. 1-4 is used for illustrative purposes only while there are many retractable coverings which could find use for the system of the present invention. This system would find use in most any retractable covering wherein exposed lift cords are utilized for reciprocally moving a bottom rail toward and away from a headrail for the covering.
  • FIG. 1 shows a retractable covering 22 from the front and it will there be seen the covering includes a headrail 24 in which a significant portion of the control system for the covering is concealed, a bottom rail 26, and a flexible shade material 28 in the form of a fabric extending between the headrail and the bottom rail.
  • the fabric has a rear sheet 30, seen best in FIGS. 2-4, which extends continuously from the headrail to the bottom rail and includes rearwardly directed vertically spaced and horizontally extending pleats 32.
  • a front sheet 34 of the fabric is connected as with adhesive, stitching, or the like, to the rear sheet along vertically spaced horizontal lines of connection 36 with a droop or loops of the front sheet being established between each line of connection due to the fact that the amount of material on the front sheet between the lines of connection is greater than the spacing between the lines of connection.
  • the covering as best appreciated by reference to FIG. 1 , therefore resembles a Roman shade.
  • a plurality of guide rings 40 are secured as with threads, adhesive, or the like to each pleat 32 on the rear sheet 30 to define vertical columns of the guide rings.
  • the vertical alignment of the guide rings in each column provides a passage for vertically extending lift cords 42, which are anchored at their lower end to the bottom rail 26 and at their top end in the headrail 24 to a roller (not seen) or other system whereby the lift cords can be retracted into the headrail to shorten their effective length thereby raising the bottom rail as desired.
  • a roller not seen
  • unrolling the lift cords from the roller allows the effective length thereof to be extended and consequently the bottom rail to be lowered when the covering is moved from a retracted position with the bottom rail adjacent to the headrail to an extended position as shown in FIGS. 1-3.
  • the lift cords form part of the control system for the covering and are raised and lowered with a pull cord 44 in a conventional manner.
  • a conventional pull cord lock (not seen) permits the pull cord to be releasably positioned at any desired position to releasably secure the covering in a partially extended or retracted position.
  • the fabric 28 is gathered between the bottom rail and the headrail with FIG. 4 showing a partial gathering thereof.
  • FIG. 4 is primarily included to illustrate how a loop 46 of lift cord can be formed off the rear of such a covering with the loop being large enough to encapsulate a body part of an infant or child.
  • the loop can be intentionally or unintentionally formed by grabbing a lift cord 42 and pulling it laterally, which thereby causes the bottom rail 26 to elevate, as a loop of significant size is formed. It is a loop 46 of this size in a lift cord which can be avoided through the present invention as will be explained hereafter.
  • FIGS. 5-9 a first embodiment of a system for preventing an enlarged loop as shown in FIG. 4 from being intentionally or inadvertently formed in a lift cord 42 is illustrated.
  • the essence of the invention resides in providing a flexible, non-extensible protector 48 associated with each lift cord with the protector being secured to the fabric 28 at vertically spaced locations and with the spacing of such locations being insufficient to form a loop in the protector of sufficient size to cause damage to an infant or child.
  • the protector in turn is operatively associated with a lift cord so that a loop could also not be formed in the lift cord of a size sufficient to cause injury to a child or infant.
  • the protector 48 is a miniturized cord ladder.
  • Cord ladders are commonly used in Venetian blinds (not shown) to support, raise and tilt horizontal slats in the blind.
  • the cord ladder 48 has a pair of substantially vertically extending elongated flexible side runs 50, which are interconnected by substantially horizontally extending flexible rungs 52, at locations spaced along the length of the side runs.
  • the runs and rungs are all formed from flexible cord-like material establishing an open ladder-type element that is elongated and can extend from a connection in the headrail 24 of the covering to a connection to the bottom rail 26 while having a lift cord 42 (FIG. 6) woven in and out of the rungs thereof while being partially exposed.
  • each guide ring 40 secured to a pleat 32 in the rear sheet 30 of the fabric 28 is inserted through a space 54 in the cord ladder or protector 48 between adjacent rungs 52 and the longitudinal side runs 50 with that space being slightly smaller than the diameter of a guide ring in a neutral orientation.
  • the flexibility of the runs and rungs allow the cord ladder to be stretched over a guide ring and into a position in which the cord ladder is not easily removed from a guide ring.
  • the guide rings therefore hold the cord ladder in position at each location of a guide ring and therefore secure it to the fabric at those locations.
  • the cord ladder is attached to the guide rings so that it extends in a non-looped orientation between guide rings when the covering is extended whereby a fixed length of cord ladder is established between each guide ring. That fixed length of the cord ladder is sufficient to allow the fabric for the covering to be fully extended as shown, for example, in FIG. 5.
  • the cord ladder 48 is also positioned relative to an associated lift cord 42 so that the lift cord is slideably woven in and out of the rungs 52 (FIG. 6) with the lift cord extending behind one rung and in front of the next adjacent rungs.
  • the lift cords are each positively and operatively connected to the cord ladder with the cord ladder being similarly operatively connected to the fabric 28 via the connection with the guide rings 40.
  • the rungs of the ladder above and below the ring would retain the ladder adjacent to the ring by the interference of the lift cord which is routed through the ring.
  • the lift cords also pass slidably through each guide ring so they are held in closely adjacent relationship to the fabric for reliable operation of the covering.
  • FIG. 7 is a side view showing the relationship of the front 34 and rear 32 sheets of the fabric, the guide rings 40, the cord ladders 48 and the lift cord 42 as seen in isometric in FIG. 6.
  • a loop 56 has been formed in a lift cord 42 as well as the protector cord ladder 48 in which it is confined off the rear face of the fabric 28.
  • the size of the loop 56 will be limited to the spacing of the adjacent guide rings 40 and the length of cord ladder 48 extending therebetween.
  • the length of cord ladder extending between adjacent guide rings is fixed so that the loop 56 formed, as shown in FIG. 8, has a maximum predetermined size which is known to be smaller than that which would be necessary to endanger a child or infant by encapsulating a body part.
  • the loop is shown in greater detail in the enlarged isometric of FIG. 9.
  • the fixed length of the cord ladder between adjacent guide rings only permits the relatively small loop 56 to be formed which elevates the bottom rail 26 a small distance but cannot elevate the bottom rail any greater distance, such as shown in FIG. 4, due to the operative relationship between the cord ladder, the guide rings and the lift cord.
  • FIGS. 10-12 A second embodiment of a protector in accordance with the present invention is shown in FIGS. 10-12.
  • the protector 60 is in the form of an elongated flexible base cord 62 having a plurality of flexible loops of cord 64 or the like formed thereon with the loops of cord being equally spaced along the length of the base cord so as to define an open structure.
  • a somewhat resilient clip 66 is positioned on the main cord which might be fixed to the main cord in any predetermined way such as by crimping, adhesive, molding or the like.
  • Each clip has an elongated sleeve 68 for receiving the base cord and a C-shaped clasp 70 extending laterally from the sleeve adapted to releasably grip a guide ring 40.
  • the C- shaped clasp has a circular passage 72 therethrough which is slightly larger than a transverse section through a portion of a guide ring while an open neck entry 74 into the passage has a dimension slightly smaller than the cross-section of a guide ring which permits the guide ring to be forced therethrough due to the resiliency of the material from which the clasp is made.
  • each guide ring is therefore connected to a clip which is positively positioned along the length of the protector cord 60 so that the protector cord cannot move to any significant degree relative to a guide ring.
  • a fixed length of protector cord substantially equivalent to the spacing between adjacent guide rings on the fabric, is therefore established between each guide ring similarly to the fixed length of cord ladder in the embodiment of FIGS. 5-9.
  • a lift cord 42 associated with a protector cord is slideably threaded through the cord loops 64 formed off the base cord 62 so that the lift cord is slideably confined to the base cord but partially exposed along its length.
  • the size of a loop that could be formed in the protector cord and the lift cord operatively associated therewith is of a limited size and of a size that is predetermined so that any such loop could not encapture a body part of a child or infant and therefore causes harm.
  • FIGS. 1 A third embodiment of the present invention is shown in FIGS.
  • the protector 76 is an elongated flexible tape or ribbon which could be of any suitable materials such as fabric, flexible plastic, a rubberized material or the like.
  • the tape or ribbon 76 as seen best in FIG. 14 is elongated and thin in dimension so as to be flexible and will readily buckle transversely when the covering is moved from an extended to a retracted position.
  • the tape is secured within the headrail 24 at a top end and to the bottom rail 26 at a bottom end and has a plurality of equally spaced, vertically aligned circular apertures or openings 78 therethrough which are interspersed at periodic intervals with elongated vertical slots 80.
  • the elongated slots are adapted to receive a guide ring 40 when the guide ring is twisted into a vertical orientation and when the guide ring resumes its neutral position, which is non vertical, the ring releasably secures the tape to the rear side of the fabric 28.
  • the lift cord 42 is threaded through the tape as illustrated in FIGS. 13 and 15 so as to be partially exposed and so that it will slide longitudinally of the tape.
  • the lift cord When the effective length of the lift cord is shortened to raise the covering from an extended to a retracted position, the lift cord of course raises the bottom rail toward the headrail causing the fabric and the protector tape to gather therebetween.
  • the protector due to the fact that the protector is secured to the fabric at spaced locations identified by the guide rings, the length of the protector between adjacent guide rings is fixed. It would, therefore, be very difficult for a loop to be formed in the lift cord greater than that permitted by the fixed length of tape between adjacent guide rings. In this manner, a loop cannot be made large enough to encapsulate a body part of an infant or child.
  • the protector 82 in the fourth embodiment comprises an elongated spirally woven open sheath formed from a plurality of nylon or other fibers or cords 83 which constrict in transverse cross section when stretched longitudinally or transversely as in a well known "Chinese finger cuff'.
  • the sheath surrounds a lift cord 42 as shown in FIG. 17 while leaving it exposed and includes a plurality of somewhat resilient C-clips 66 of the type shown in the embodiment of FIGS. 10-12.
  • Each sleeve 68 of a C-clip is secured in position along the length of the lift cord and sheath with adhesive, crimping, molding, or in any other suitable manner.
  • Each C-clip has a C-shaped clasp 70 having a circular passage 72 therethrough adapted to receive a guide ring 40 with an open neck 74 communicating with the circular passage that is slightly smaller than the transverse cross section of a guide ring so that the guide ring can be snapped into the clasp due to its resiliency.
  • the lift cord with the sheath surrounding it along its entire length can be threaded through the guide rings with the C-clips being attached to an associated guide ring thereby defining a fixed length of sheath between adjacent guide rings.
  • the lift cord is axially slidable within the sheath to move the bottom rail toward or away from the headrail and when the bottom rail is being moved toward the headrail, the sheath is collapsed (FIGS. 19 and 20) along each segment between C-clips thereby even expanding in transverse cross section to permit easy sliding movement of the lift cord therethrough.
  • FIGS. 21 and 22 A fifth embodiment of a protector in accordance with the present invention is shown in FIGS. 21 and 22.
  • This embodiment 86 of the protector is shown in FIG. 21 incorporated into a covering of the type shown in FIGS. 1-4 and, accordingly, like parts of the covering have been given like reference numerals.
  • the protector 86 itself is simply an elongated flexible cord of the type used in coverings for architectural openings as pull cords, lift cords or the like, but has been woven in a unique manner to define open pockets or gaps 88 sized to permit a guide ring 40 to be snuggly fitted therethrough to secure the protector to the fabric 28 for the covering.
  • the protector can be seen to be an elongated flexible cord which is unitary at spaced locations 90 along the length of the protector and then is bifurcated into two parallel legs 92 between adjacent unitary segments.
  • the cord is bifurcated, it forms the open pocket or gap 88 through which the guide ring can be inserted by orienting the guide ring vertically and then when the guide ring resumes its neutral more horizontal disposition, it locks the protector 86 to the fabric.
  • the protector thereby becomes secured to the fabric at spaced locations corresponding to the locations of the guide rings on the fabric so that a fixed length of the protector extends between guide rings as in the prior embodiments.
  • the lift cord 42 is then woven through the gaps in the protector so that it is exposed and slides axially relative to the protector, but as in the prior embodiments, the protector prevents loops larger than a predetermined size from being formed in the lift cord either intentionally or inadvertently due to the fact that the protector, to which the lift cord is operatively associated, is of a fixed length between guide rings with that fixed length being insufficient to form a loop larger than the predetermined size.
  • FIGS. 23 and 24 A sixth embodiment of the protector in accordance with the present invention is shown in FIGS. 23 and 24.
  • This embodiment 90 of the protector is shown in FIG. 23 incorporated into a covering of the type shown in FIGS. 1-4 and accordingly, like parts of the covering have been given like reference numerals.
  • the protector 90 itself is comprised of a pair of flexible main cords 92 of the type that might be conventionally used as lift cords or pull cords in a covering for architectural openings with the cords being positioned in spaced parallel side-by-side relationship and being integrated or tied together at longitudinally spaced locations by loose stitching with cross cords 94 of a similar material to the main cords but being of approximately half the diameter of the main cords.
  • the cross cords which tie the main cords together, extend transversely, as by sewing, from one main cord to the opposite main cord and then back in reversing directions similar to shoe lacing with both ends of the cross cords being secured to one or both of the main cords.
  • Elongated zones of stitching 96 extending between the main cords are spaced from adjacent zones of stitching so that longitudinally-extending spaces 98 between the main cords are defined between the stitched zones 96.
  • the stitched zones may be approximately the same length as the longitudinal spaces 98 between the zones defining an open structured protector.
  • the cross cords obviously are flexible so they can reverse directions, due to their short lengths between the main cords, they resist buckling and therefore maintain a predetermined spacing between the main cords. Also, where the cross cords pass through a main cord, they resist sliding movement due to friction so they stay in position while holding the predetermined spacing between the main cords.
  • the protector 90 is attached to the covering 22 for the architectural opening by inserting the guide rings described previously on the back of the covering through one of the longitudinal spaces in the protector so that the protector is removably positioned on the rear side of the covering. Between guide rings there is a plurality of the longitudinally spaced spaces so that the lift cord, which is conventionally passed through the guide rings, is openly woven through the longitudinal spaces as best seen in FIG. 25 thereby openly confining the lift cord between rings to prevent large loops in the lift cord from being formed.
  • the protector of the present invention has been described in association with a fabric having guide rings attached to the fabric which can be used to connect the protector to the fabric. It should be appreciated the protector can be attached to the fabric or other covering in any suitable fashion. For example, if the covering had a plurality of horizontally oriented vertically spaced rigid slats or battens, clips or brackets could be secured to the slats or battens to which the protector could be connected.

Abstract

Un système destiné à être intégré dans un revêtement rétractable comprend un cordon de levage flexible s'étendant d'une traverse supérieure à une traverse inférieure. Le système inclut une protection flexible d'une longueur identique à celle d'un cordon de levage associé, le cordon de levage étant relié fonctionnellement à cette protection. Celle-ci est elle-même reliée à un tissu s'étendant entre la traverse supérieure et la traverse inférieure en des points espacés prédéterminés, de telle sorte que toute boucle de la protection susceptible de se former soit limitée par l'espace entre les points auxquels la protection est reliée au tissu. La taille maximale d'une boucle ainsi formée dans la protection et donc du cordon de levage associé à celle-ci est insuffisante pour englober une partie du corps d'un enfant ou d'un bébé.
