Abstract
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
