A retrofit blind assembly for a doorlight. The assembly includes a frame, a transparent panel, and a blind snap-fitted to the frame. The blind actuator includes gears and a toothed belt for positive, non-slip actuation. A pair of blind guides are mounted on the opposite sides of the frame to receive and guide the opposite ends of the blind. The mounting system includes a pair of brackets that can be secured between the doorlight and the door and upon which the assembly can be hung. The mounting system also includes a pair of movable catches on the lower portion of the frame snap that can be locked behind the doorlight to secure the lower end of the assembly.
Description




BACKGROUND OF THE INVENTION




The present invention relates to window blind assemblies and, more particularly, to a blind assembly particularly well adapted for mounting over doorlights.




Window units incorporating blinds are well known in the prior art. These units include two panes of glass an a blind assembly sandwiched between the two panes. The blind assemblies include mechanisms both for raising and lowering the blinds and for tilting the blind slats. The units include slides or knobs or handles coupled to the mechanisms and accessible from the outside of the unit. When a window unit is especially designed or adapted for installation in a door, the unit is referred to as a doorlight.




Because it is difficult, time-consuming and costly to replace existing doorlights with doorlights having integral blinds, retrofit assemblies have been developed for retrofitting blinds over doorlights. These retrofit assemblies include a frame that supports both a pane of glass and a blind assembly. The frame is attached over the frame of the existing doorlight such that the blind assembly is sandwiched between the pane of the assembly and the existing doorlight. Screws are typically used to attach the assembly to the doorlight and/or the door. One particularly good example of a retrofit assembly is illustrated in U.S. Pat. No. 5,996,668 issued Aug. 14, 1998 to DeBlock et al.




Retrofit units are superior to the simple attachment of a blind assembly first because the retrofit units protect the blinds from wear and tear and encase the cords of the blind assembly. Freely hanging cords can be a hazard to children and pets. Second, the retrofit unit confines the blind and prevents the blind from swinging into the door as the door is opened and closed or during high winds, thus preventing damage to the blind and the door. Finally, the encased window blind is more aesthetically pleasing than a traditionally hung window blind; and the encased blind requires cleaning less frequently, if ever.




Despite the advantages of these systems, there is room for improvement. First, the cords in the units can become tangled if the blind is permitted to free fall within the unit and/or if the unit is inverted (e.g. prior to or during installation). Second, the mechanism of the units often are visible along the sides or edges, contributing to an unsightly appearance. Third, the units require a considerable amount of time to install. Fourth, the fasteners for the units leave permanent marks (e.g. holes) in the face of the door, which are unsightly if the retrofit unit is removed. Fifth, stocking of units of blinds having different colors creates a significant inventory issue. Sixth, replacing a blind in a unit is extremely difficult, if not impossible. This can be a problem if a consumer wishes to change the color of the blind assembly or if a defective blind must be replaced. A consumer usually replaces the entire unit if they wish to change the color of the blind.




SUMMARY OF THE INVENTION




The present invention overcomes the noted problems by providing a an improved retrofit doorlight blind assembly having several novel features.




In a first aspect of the invention, the operator mechanism for the raise/lower feature includes gears and a toothed drive belt to ensure positive engagement of the drive mechanism. More particularly, a first gear drives the blind operator rod; a second gear provides an idler, and the toothed belt is looped around the two gears to provide the driving mechanism.




In a second aspect of the invention, the frame includes multipurpose blind guides. First, the guides have a C-shaped section that surrounds the edges of the blind to guide the blind during raising and lowering. Second, the guides secured the glass panel within the frame. Third, the guides hide the mechanism from view. And, fourth, the guides reinforce the frame.




In a third aspect of the invention, the assembly includes an improved mounting system for mounting the retrofit assembly over a doorlight. More specifically, the mounting system includes a top bracket that is secured behind the top of the doorlight frame on which the assembly is easily hung. The system also include latches that lock behind a lower portion of the doorlight frame to secure the bottom of the assembly.




In a fourth aspect of the invention, the blind snap-fits into the assembly frame so that the blind is easily attached to and detached from the frame. Specifically, the blind assembly includes a catch that snaps into a slot on the header. This feature reduces inventory, because assemblies can be made to order by snapping any one of a plurality of blinds (e.g. having a desired feature such as color) into a common frame. This feature also facilitates subsequent changes to the assembly, such as replacing a blind having one feature with a blind have a different feature.




In a fifth aspect of the invention, the blind actuator rod includes an improved technique for securing the actuator cords. More specifically, small barrels are mounted transversely in the rod; and the actuator cords are secured within the barrels. This technique eliminates the prior art need to glue the cords to the barrel, with the attendant manufacturing difficulties and costs.




These and other objects, advantages, and features of the invention will be more readily understood and appreciated by reference to the detailed description of the preferred embodiment and the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




A blind assembly according to a preferred embodiment of this invention is illustrated in

FIGS. 1-3

and generally designated


10


.




I. Structure




The assembly


10


includes a window pane


12


, a frame


20


, a set of blinds


22


, a tilt control mechanism


24


, and a height control mechanism


26


. The assembly


10


is described for installation over a door D and doorlight L. However, the assembly


10


may be installed over other, various window types.




The frame


20


is preferably molded of plastic, although other materials, such as wood or metal, may be used. The frame


20


includes top and bottom sides


28


and


30


and left and right sides


32


and


34


. The sides


28


,


30


,


32


, and


34


meet at right angles and form a rectangle, although the frame


20


may include a larger or smaller number of sides and form other shapes, such as a triangle or octagon. A pane opening


36


is defined in the center of the frame


20


. Although the frame will be described with reference to a rectangular pane opening


36


, and accordingly a rectangular window pane


12


, it is to be understood that the opening can be of essentially any shape, such as oval or triangular.




Each of the bottom, left and right sides


30


,


32


, and


34


of the frame


20


includes a rib


40


, extending along its length. As shown in

FIG. 5

, the rib


40


is a substantially rectangular protrusion that extends approximately the length of the pane opening


36


on each side of the frame


20


. The rib


40


is preferably integrally molded as part of the frame


20


, however the rib


40


may be separately formed and attached to the frame


20


by conventional means.




Connected to each rib


40


is a blind guide


42


. Blind guides


42


are preferably molded of plastic, but may be produced of other materials such as metal or plastic. As will be explained below, the blind guides


42


guide the blinds


22


during use and secure the pane


12


to the frame


20


. Further, the blind guides


42


reinforce the frame


20


and prevent viewing of the internal workings of the assembly


10


when the assembly is installed. Each blind guide


42


has a connecting portion


44


and a blind retainer


46


.




The connecting portion


44


is a substantially U-shaped section of each blind guide


42


that defines a cavity, the cavity fitting over a rib


40


of the frame


20


. As shown in

FIG. 5

, the dimensions of the connecting portion


44


are preferably such that there is a close fit between each connecting portion


44


and the corresponding rib


40


. When connected to the rib


40


, a first leg


48


of the connecting portion


44


is in contact with the pane


12


and a second leg


50


of the connecting portion


44


is in contact with the frame


20


. This construction secures the pane


12


to the frame


10


. The connecting portion


44


can be connected to the rib


40


by any conventional means, such as the use of glue or fasteners.




Further, each blind guide


42


includes a blind retainer


46


. The blind retainer is an essentially C-shaped section of the blind guide


42


and is connected to the connecting portion


44


. The width


52


of the blind retainer


46


is approximately equal to the width


54


of the blinds


22


. When connected, the open side of the blind retainer


46


faces the pane


12


of the assembly


10


, providing a channel for the blinds


22


to travel in as they are raised and lowered during use. As with the connecting portion


44


, the blind guide has one leg


56


that contacts the pane


12


of the assembly


10


.




The connecting portion


44


and blind retainer


46


are preferably molded as an integral piece, though the elements can be formed separately and later connected. If molded as an integral piece, the back leg


58


of the blind retainer


46


and the first leg


48


of the connecting portion


44


are preferably molded as a single leg, thus connecting the two sections. If not molded as an integral piece, the back leg


58


of the blind retainer


46


is preferably connected to the first leg


48


of the connecting portion


44


by conventional means, such as the use of glue or other adhesive.




The set of blinds


22


are conventional window blinds and, therefore, will not be described in detail. The blinds include a plurality of slats


64


, preferably manufactured of vinyl or aluminum; of course, other materials such as wood may be used. As discussed above, the blinds


22


, and specifically the ends


66


and


68


of the slats


64


of the blinds


22


, are loosely retained in the blind retainers


46


of the left and right sides


32


and


34


of the frame


20


. A header


70


, as seen in

FIG. 4

, from which the slats


64


are suspended, is fixedly mounted on the top side


28


of the frame


20


. The slats


64


are suspended from conventional lift adjustment and tilt adjustment, or string ladder, tilt cords


74


. The lift cords


72


have first and second ends


75


and


76


; the first ends


75


are threaded through apertures (not shown) defined by the slats


64


and secured to the lowermost slat


77


. The second end


76


of each lift cord


72


is secured within the header


70


. Front and rear tilt cords


78


and


79


extend along the front and rear edges


80


and


82


of the slats


64


. A connector cord (not shown) extends between the front and rear tilt cords


74


and supports each slat


64


. The tops of the tilt cords


74


are secured within the header


70


.




The header


70


is a substantially L-shaped bar that is connected to the top side


28


of the frame such that a ledge is formed along the top edge of the pane


12


. The header


70


can be connected to the frame


20


by any conventional means, such as integrally molding the header


70


as part of the frame


20


or connecting the two using an adhesive. The header


70


includes an attachment leg


106


. The attachment leg


106


is a short protrusion extending at a right angle from the back leg


108


of the header


70


such that the back leg


108


of the header


70


lies flat against the pane


12


and the attachment leg is connected to the interior of the frame


20


. The header


70


further includes a base leg


110


having slots


112


for the connection of the tilt control mechanism


24


and height control mechanism


26


to the frame


20


. Each slot


112


is a substantially rectangular groove in the base leg


110


of the header


70


.




As seen in

FIGS. 4 and 5

, the tilt control mechanism


24


includes a tilt actuator


84


, which is slidably mounted along the left side


32


of the frame


20


. The tilt actuator


84


includes a spine


86


that protrudes from the tilt actuator


84


and fits within a groove


85


present along the left side


32


of the frame. The spine


86


is preferably a substantially rectangular protrusion and the groove


85


is preferably substantially U-shaped, the height of the spine


86


being approximately equal to the depth of the groove


85


. Additionally, the tilt actuator


84


includes a rearward extending connector


88


for connecting to the remainder of the tilt control mechanism


24


, as will be explained in more detail below. The connector


88


extends inwardly from this the groove


85


into the interior of the frame


20


. Preferably, a portion of the edge of the frame is cut away along the groove


85


to facilitate movement of the tilt actuator


84


, the tilt actuator


84


being positioned along this cut-away portion


87


.




The remainder of the tilt control mechanism


24


is located within the interior of the frame


20


and is not visible to the user. The tilt control mechanism


24


further includes a tilt belt


90


attached to the tilt actuator


84


by the connector


88


. The tilt belt


90


wraps around a tilt gear


92


that is affixed to a tilt bar


94


, preferably with screws or adhesive. The tilt belt


90


preferably includes grips


98


that interfit with teeth


100


on the gear to provide a more secure grip between the two. A tilt control gear


93


is essentially identical to the tilt gear


92


and is mounted at the bottom of the frame


20


. The tilt gear


92


and tilt control gear


93


control rotation of the tilt belt


90


during operation of the assembly


10


. The tilt belt


90


is most preferably molded from plastic, although other suitable materials such as rubber and fabric may be used. A portion of the tilt belt


90


optionally consists of a spring


102


, the spring


102


accounting for thermal expansion of the resulting belt. The tilt bar


94


extends lengthwise within the interior of the header


70


and is supported within barrel


114


which snaps into the floor of the header


70


. The front and rear tilt adjustment cords


78


and


79


are secured to the tilt bar


94


.




The tilt gear


92


and tilt control gear


93


are housed within baskets


104


. Each basket


104


includes two side walls


106


and a back wall


108


. Each side wall includes a nesting portion


110


, which is a substantially semicircular ridge along the top edge of the wall. The tilt gear


92


and tilt control gear


93


rest on the nesting portions


110


of the side walls


106


. The back wall


108


connects the basket


104


and is attached to the frame


20


. The back wall


108


can be connected to the frame


20


by any conventional means, such as screwing the back wall


108


onto the frame


20


or attaching the two with an adhesive.




The height control mechanism, or adjuster,


26


includes a height actuator


120


which is slidably mounted on the right side


34


of the frame


20


. The height actuator


120


is essentially identical to the tilt actuator


84


and includes a spine


122


which interfits with a groove


124


on the right side


34


of the frame


20


. As with the tilt control mechanism


24


, the groove


124


preferably includes a cut-away portion to facilitate movement of the height actuator


120


, and thus adjustment of the blinds


22


. The height actuator


120


further includes a connector


126


that connects the height actuator


120


to the height control mechanism


26


.




The connector


126


of the height actuator


120


is attached to a height belt


128


which is wrapped around an adjustment gear


130


and adjustment control gear


131


, which are housed in baskets


104


. The height belt


128


, adjustment gear


130


and adjustment control gear


131


are essentially identical to the tilt belt


90


, tilt gear


92


and tilt control gear


93


, and therefore will not be described in further detail. The height control mechanism


26


further includes an adjustment rod


136


, a threaded rod


138


, and a rod support


140


. The adjustment rod


136


is a substantially circular rod that is connected to the adjustment gear


130


such that when the adjustment gear


130


rotates, the adjustment rod


136


rotates. Optionally, a bar can be used to connect the adjustment gear


130


to the adjustment rod


136


. The adjustment rod


136


, or at least a substantial portion thereof, is hollow and is internally threaded. The adjustment rod includes throughholes


137


through which the second ends


76


of the lift cords


72


are threaded. The first ends of the lift cords


72


are preferably knotted to secure them to the adjustment rod


136


. A cap


139


is also connected to the second end


76


of each lift cord


72


around the knotted portion to further ensure the connection of the lift cords


72


to the adjustment rod


136


.




The threaded rod


138


is a substantially circular rod having threads along substantially its entire the length, the threads of the threaded rod


138


corresponding to the threads of the adjustment rod


136


so that that threaded rod


138


can be screwed into the adjustment rod


136


. One end of the threaded rod


138


is screwed at least partially into the adjustment rod


136


and the opposite end of the threaded rod


138


being rigidly connected to the rod support


140


, such that as the adjustment rod


136


rotates the adjustment rod


136


is screwed onto the threaded rod


138


. The rod support


140


preferably includes a circular portion


142


that houses an end of the threaded rod


138


and prevents the threaded rod


138


from rotating during operation of the assembly


10


. The rod support


140


also preferably includes a clamp


144


that is connected to the header. The clamp


144


is preferably substantially U-shaped and interfits with the base leg


110


of the header


70


to connect the rod support


140


to the header


70


, and thus the frame


20


. Alternatively, the rod support may be connected to the header


70


by other conventional means, such as the use of glue or fasteners.




Each of the adjustment rod


136


and tilt bar


94


extends through barrels


114


, thus connecting the tilt control mechanism


24


and height control mechanism


26


to the barrels


114


. Barrels


114


include catches


116


that interlock with the slots


112


. Each barrel


114


is essentially two

FIG. 8

shaped sections, each section having a large circle


118


beneath a small circle


120


. A base


122


is attached to the bottom of each large circle


118


and extends between the two sections to connect them. A catch


116


is a substantially T-shaped protrusion that extends from the bottom of each base


122


. Each catch


116


is designed to “snap” fit with a slot


112


on the header


70


to connect the tilt control mechanism


24


and height control mechanism


26


to the header


70


.




As can perhaps be best seen in

FIG. 8

, latches


150


are connected along the top side


28


of the frame


20


. Each latch


150


includes a short frame leg


152


connected to the top side


28


of the frame


20


and a door leg


154


that is substantially longer than the frame leg


152


and extends in a direction opposite that of the frame leg


152


. An intermediate leg


156


connects the frame leg


152


and door leg


154


and is preferably perpendicular to them both. There are preferably at least two latches


150


connected along the top side


28


of the frame


20


. Latches


150


can be formed from any materials, but are preferably metal, and can be connected to frame


20


in any conventional manner.




As can be seen in

FIG. 9

, clips


160


are connected along either the bottom side


30


or a lower portion of both the left and right sides


32


,


34


of the frame


20


. Each clip


160


is substantially L-shaped and includes a base leg


164


and an extending leg


166


. Each clip


160


optionally includes a substantially rectangular lip


162


extending perpendicularly from the base leg


164


of the clip


160


. The clips


160


are rotatably connected to the frame


20


such that, if the lip


162


is pulled, the clip


160


rotates. The clips can be connected to the frame by any conventional means, but are preferably connected to the frame


20


with screws.




II. Operation




The assembly


10


is preferably installed over the doorlight of an existing door. However, the assembly


10


may be used in conjunction with any window style or with windows in any type of structure, such as a home or office building.




Before installing the assembly, the blinds


22


must be installed. To install the blinds


22


, the catches


116


of the barrels


114


connected to the tilt control mechanism


24


and the height control mechanism


26


, which in turn are connected to the blinds


22


, are snapped into slots


112


on the header


70


. To change the color of the blinds, the barrels


114


can be detached from the header


70


and new barrels


114


, with new blinds


22


, can be snapped in.




After installing the blinds, the assembly


10


is positioned so that the blinds


22


are sandwiched between the pane


12


and the existing doorlight. To install the assembly


10


on a doorlight, the latches


150


of the assembly


10


are first placed over the existing frame of a doorlight in such a manner as to allow the door leg


154


of each latch


150


to “snap” in between the frame of the existing doorlight and the door. The snapping interaction of the latches


150


and the existing frame provides a secure connection of the assembly to the door.




After connecting the assembly


10


to the door, the clips


160


are rotated such that the extending leg


166


of each clip


160


“snaps” between the frame of the existing doorlight and the door. In this case, the securing of the clips


160


between the doorlight frame and door prevents the assembly


10


from swinging or swaying as the door is opened or closed or during windy conditions.




To raise or lower the blinds


22


, the user grasps the height actuator


120


of the height control mechanism


26


and slides height actuator


120


vertically along the cut away portion


132


of the groove


124


. As the user slides the height actuator


120


down, the height belt


128


is moved downward, thus rotating the adjustment gear


130


and, in turn, the adjustment rod


136


. As the adjustment rod


136


rotates, it is threaded onto the threaded rod


138


and the lift cords


72


are coiled onto the adjustment rod


136


, thus pulling the slats


64


vertically upward. The slats


64


may be raised to any height desired by the user. When the slats


64


are raised to the desired position, the user ceases sliding the height actuator


120


down the track


40


.




To lower the blinds


22


, the user slides the height actuator


120


vertically upward along the groove


124


. As the height belt


128


is pulled upward, the adjustment gear


130


is rotated in the opposite direction, causing the lift cords


72


to unwind from the adjustment rod


136


and lower the slats


54


.




To open the blinds


22


, the user grasps the tilt actuator


84


and slides it along the groove


85


along the left side


32


of the frame


20


to the middle of the left side


32


. As the tilt actuator


84


is moved, the tilt belt


90


is moved causing the tilt gear


92


to rotate. As the tilt gear


92


rotates, the tilt cords


74


are twisted causing the slats


64


to rotate. When the tilt actuator


84


is positioned in the middle of the assembly


10


, the front and rear tilt cords


74


are level, and the connector cords are horizontal. Thus, the slats


64


lie in a horizontal position, and the blinds


22


are opened. To close the blinds


22


, the user slides the tilt actuator


84


to upwards or downwards from the middle position. This causes the tilt gear


92


to rotate, thus rotating the tilt bar


94


and causing the tilt cords


74


to twist. As the tilt cords


74


twist, one edge of the slats


64
