Definitions

  • the present invention relates to a window covering that may be raised without the need to apply a force to either a control mechanism or the window covering itself as the window covering is opened.
  • the present invention relates to a window covering having a control mechanism configured to exert an upward force on the shade element and bottom rail that is of sufficient magnitude to raise the shade element and bottom rail without additional force being applied by the user during raising.
  • Window shades and coverings are found in many applications and used to regulate the amount of light entering a room, and to provide aesthetic appeal to a decor. Such window shades and coverings take many forms, including roller shades, Roman shades, Venetian blinds, and cellular shades.
  • Conventional cellular or pleated shades utilize cord locks or a transmission mechanism to raise, lower and position the window covering in a desired position. With window coverings utilizing a cord lock, cords run up through the folded fabric, across the inside of a head rail and exit through a locking mechanism.
  • Other cellular shades include a transmission mechanism and a continuous loop cord that is pulled by a user to raise and lower the window shade.
  • Roman shades and Venetian blinds also tend to include raising cords that are secured to a lower bar or bottom rail.
  • Cords present the potential hazard of a child getting caught in or strangled by the exposed control cord.
  • Cords also tend to distract from the aesthetics of a window covering in that they extend along the face of the window covering and, when the window shade is opened, must either be wrapped on a hook or just left on the floor.
  • window coverings that utilize cord locks the cords also experience substantial wear due to friction against surfaces as a result of raising and lowering of the window covering.
  • roller shades which operate in the absence of a cord.
  • These roller shades include a wound torsion-spring retraction mechanism in combination with a clutch or locking mechanism mounted with a roller onto which the shade is rolled and collected.
  • a roller shade is pulled down by a user to a desired location, where it is locked in place by the clutch or locking mechanism.
  • the user typically pulls on a bottom rail of the shade, extending the shade sufficiently to disengage the internal clutch or locking mechanism within.
  • the clutch or locking mechanism is disengaged and the user releases the shade, the shade is retracted using the torsion-spring driven retraction mechanism.
  • Known roller shades are only operable with flat shade material which rolls up neatly into a confined location.
  • roller shades are not compatible with other window coverings, such as cellular shades, Venetian blinds, and Roman shades.
  • window coverings such as cellular shades, Venetian blinds, and Roman shades.
  • a similar lifting mechanism is typically unsuitable in cellular shades, Venetian blinds, and Roman shades.
  • the material of the shade element is typically gathered by raising a bottom member, such as a bottom rail, and increasing amounts of weight are gathered on the bottom member as the window covering is raised. The reason for this is that the shade material or shade element increasingly stacks on the bottom rail as the bottom rail rises, which increases the load on the lifting mechanism.
  • variable force springs have been used. Such variable force springs are substantially more complicated in use and manufacture.
  • window covering raising mechanism for window coverings such as Venetian blinds, cellular shades and Roman shades that is self-raising and overcomes the foregoing problems.
  • the present invention relates to a self-raising window covering and a control mechanism for the window covering.
  • the window covering is a self-raising window covering that includes a head rail, a shade element, such as a cellular panel, blind slats, or Roman shade material, a bottom rail, at least one raising cord operatively connected at a first end to the bottom rail, and a control mechanism.
  • the head rail may define an elongated channel wherein the control mechanism is disposed therein.
  • the control mechanism includes a drive axle and a drive unit operatively connected with the drive axle.
  • the drive unit which may be a constant force spring, is adapted to provide a substantially constant rotational force on the drive axle.
  • At least one cord winding assembly is also provided in co-axial relation with the drive axle.
  • the number of cord winding assemblies will be the same as the number of raising cords.
  • one cord winding assembly may be adapted to operate with multiple cords.
  • the cord winding assembly includes at least one winding drum operatively connected to a second end of the raising cord and having a tapered portion.
  • the cord winding assembly also includes a rotatable positioning member for moving the cord winding assembly laterally along the drive axle upon rotation of the positioning member.
  • the positioning member is a threaded tubular member connected to the winding drum.
  • the cord winding assembly is adapted to translate the rotational force on the drive axle to a raising force on the raising cord, wherein the raising force is greater than a total downward force exerted by the shade element and bottom rail throughout the range of opening and closing.
  • the cord winding assembly is rotationally secured with the drive axle by a hub member adapted to engage the cord winding assembly and the drive axle.
  • the hub member may be in a sliding relationship with the tapered portion of the cord winding assembly.
  • a clutch member or locking member is also operatively connected with the axle and adapted to releasably lock the drive axle in a desired position.
  • the clutch member comprises a reciprocator disposed coaxially relative to the drive axle and movable between a released position and a locked position, and a spring member connected to the reciprocator and operable to either tighten or relax the hold of the reciprocator on the drive axle.
  • the reciprocator is configured to cause the spring member to tighten on the drive axle in the locked position for blocking a rotation of the drive axle against the rotational force applied by the drive unit, and cause the spring member to relax the drive axle in the released position to permit a rotation of the drive axle under the rotational force applied by the drive unit
  • FIGURE 1 an embodiment of a self-raising window covering 10 according to the present invention is shown.
  • a head rail 12 defining a channel is provided.
  • a pair of drive units, such as spring units 14 and 16 are coaxially mounted about a drive axle 18.
  • cord winding assemblies 20 and 22 are mounted on drive axle 18.
  • Each of cord winding assemblies 20 and 22 includes a frustoconical winding drum 24 and 26, and a threaded tubular member 32 and 34, respectively.
  • Raising cords 28 and 30, which are shown as wound on winding drums 24 and 26, are secured at an end to the winding drums 24 and 26.
  • a clutch 36 is also provided and co-axially mounted on the drive axle 18.
  • Window covering 10 further includes a shade element, such as cellular shade material 38 and a bottom member, such as bottom rail 40.
  • a shade element such as cellular shade material 38
  • a bottom member such as bottom rail 40.
  • the term "cord” as used may encompass a cord, strip, ribbon, string or any similar flexible elongated elements that are suitable for supporting the suspended shade element, and can be wound or unwound to deploy or retract the shade element.
  • a relatively short length of cord 42 can also be provided so that the user can pull down the window covering and, as will be discussed in further detail, release the clutch so that the window covering will retract itself.
  • the spring unit 14 comprises a spring casing 42, a spring axle 44, a constant force coil spring 46 and a cover 48.
  • the coil spring 46 and the spring axle 44 are secured within the casing 42, which is closed by cover 48.
  • a first end 50 of the coil spring 46 is secured to the spring axle 44, which is coaxially connected to the drive axle 18 ( FIG. 1 ).
  • the coil spring is configured to provide sufficient rotational force to the drive axle 18 and winding drums 24 and 26 to raise the shade element and bottom rail.
  • Other alternative embodiments of spring units are also possible, such as shown in FIGS. 3-6 .
  • a suitable spring unit 114 shown in FIG. 3 may include a coiled spring member 146 having a first end secured with a first spring axle 142 that connects to the drive axle 18 shown in FIG. 1 , and a second end secured with a second spring axle 144 that is offset from the first spring axle 142.
  • the coiled spring 146 in a relaxed position may be initially wound around the second spring axle 144. As the shade element is pulled downward, the coiled spring 146 may stretch out from the second spring axle 144 and progressively wind around the first spring axle 142.
  • This configuration of the spring unit 114 may be suitable when the used coiled spring 146 has a greater length to allow a longer deployment range of the shade element.
  • FIG. 4 illustrates another suitable spring unit 214, which is similar to the embodiment shown in FIG. 3 except that the second end of the coiled spring does not connect to any second spring axle. Instead, the coiled spring 246 winds on itself at its second end, while the first end 252 of the coiled spring 246 connects to a single spring axle 218 connected to the drive axle 18 shown in FIG. 1 .
  • spring unit 314 includes an assembly of two coiled springs 346 and 348 that may be used to provide a greater raising force for the shade element.
  • the first coiled spring 346 has its first end connected to a first spring axle 344
  • the second coiled spring 348 has its first end connected to a second spring axle 345.
  • the second end of the first coiled spring 346 and the second end of the second coiled spring 348 respectively connect to a third spring axle 318 located between the first and second spring axles 344 and 345 and connected to the drive axle 18.
  • the coiled springs 346 and 348 may respectively stretch out from the first and second spring axle 344 and 345 to progressively wind around the third spring axle 318 to apply an increased raising force on the drive axle 18.
  • the shown embodiment is very similar to that shown in FIG. 5 except that the two coiled springs 446 and 448 that wind on the axle 418 connected to the drive axle do not connect with second spring axles.
  • each of the embodiments shown utilizes a spring as the driving mechanism for the drive unit, it should be understood that any suitable mechanism for imparting a rotational force on the drive axle may be utilized.
  • the rotational force exerted upon a drive axle 18 causes the cord winding assemblies 20 and 22 to rotate and translate for winding the cords 28 and 30, which thereby raises the shade element 38 vertically toward the head rail 12. Further details on a preferred embodiment of a cord winding assembly are provided with reference to FIG. 7 .
  • Cord winding assembly 20 is mounted co-axially with the drive axle 18 that passes through a fixed housing comprised of a frame 64 and upper cover 65.
  • the cord winding assembly 20 includes a winding drum 24 and a rotational positioning member, such as threaded tubular member 32, fixedly connected at an end of the winding drum 24.
  • the cord winding assembly 20 is preferably mounted on the drive axle 18 via a hub member, such as adapter 60 that is configured to transmit rotational movement between the drive axle 18 and the cord winding assembly 20 while allowing a relative translation movement therebetween.
  • the adapter 60 may be coaxially mounted inside a central hole of the winding drum 24, and include a through hole for mounting the drive axle 18.
  • a peripheral surface of the adapter 60 may be provided with radial portions that contact with ribs protruding radially inward from the surface of the central hole of the winding drum 24.
  • the threaded tubular member 32 engages with toothed rollers 66, which are rotatably mounted to frame 64 and bracket 68 fixedly secured in head rail 12. Rotational movements thereby can be transferred between the drive axle 18 and the cord winding assembly 20, while smooth relative translations with reduced frictions are permitted therebetween.
  • the engagement via the adapter 60 and the threaded tubular member 32 allows an improved support of the load of the suspended components, e.g. shade element 38 and bottom rail 40.
  • the winding drum 24 is tapered and is preferably frustoconical in shape, and may include striations or grooves to improve gripping of the cord 28 wound on the surface of the winding drum 24.
  • An end of the raising cord (not shown) is secured towards the larger diameter end 62 of the winding drum 24.
  • the cord winding assembly 20 rotates and translates in a direction to wind the raising cord 28, the raising cord is wrapped around increasingly narrower portions of the winding drum 24.
  • FIGS. 8A and 8B the raising operation of the window covering is shown.
  • the shade element 38 When the shade element 38 is fully deployed, as shown in FIG. 8A , the raising cord 28 is fully extended from a wider portion of the winding drum 24.
  • the threaded engagement between the threaded tubular member 32 and rollers 66 causes the rotating cord winding assembly 20 to move laterally within the head rail 12, such that the raising cord winds along the winding drum 24 towards its narrower end.
  • the load on the spring units is now described with reference to one of the spring units.
  • the load on one spring unit 14 is derived with an adequate scale factor from a momentum M on the drive axle 18 that can be approximated by the product between the suspended weight W, including the weight of the bottom rail plus the amount of shade element 38 stacked thereon, and a winding radius R of the winding drum 24.
  • W will increase, and R will decrease because the raising cord 28 winds on increasingly narrower portions of the tapered winding drum 24 that slide with reduced frictions owing to the adapter 60 and threaded tubular member 32 and adapter 60.
  • the load M on one spring unit 14 can be kept at a level that varies slightly and can be overcome by the constant force spring 46 ( FIG. 2 ) to fully raise the bottom rail 40 and shade element 38.
  • the constant force spring 46 FIG. 2
  • a user exerts an approximately constant pulling force regardless of the position in height of the window covering.
  • spring units 14 and 16 of constant force thus can be suitably used to raise a suspended weight charge W that increases as it rises.
  • the shade element itself may have an effect on the total downward force or suspended weight.
  • an inherent upward spring bias to the material may serve to decrease the total downward force. The total contribution of this spring bias varies depending on the degree to which the cellular window covering is extended.
  • the clutch member 36 is provided in order to lock the shade element 38 and bottom rail 40 in a desired position.
  • Clutch member 36 is mounted coaxially with the drive axle 18 and is configured to unlock the drive axle 18 as the user pulls down the bottom rail 40 to stretch the shade element 38, and to lock the drive axle 18 when the user releases the bottom rail 40 at the desired height.
