B60J1/2025—Roller blinds powered, e.g. by electric, hydraulic or pneumatic actuators with flexible actuating elements connected to the draw bar for pulling only, e.g. cords, wires or cables

A motorized mechanism for actuating motion within a housing of a window shade arrangement having first and second window shades for controlling the amount of light admitted through a window. The motorized mechanism comprises a first rail assembly movable in the housing and connected to a first end of the first window shade and a first end of the second window shade, a second rail assembly movable in the housing and connected to a second end of the second window shade, a second end of the first window shade being fixed to the housing, said first and second window shades being adapted to be extended and compressed relative to the window in accordance with motion within the housing of at least one of said first and second rail assemblies. A first cable is looped between a motor-driven first pulley and a second pulley along a first path. A second cable is looped between a motor-driven third pulley and a fourth pulley along a second path. Corresponding ends at one side of said first and second rail assemblies are in said first path, with only one of said first and second rail assemblies being connected to the first cable, and corresponding ends at the other side of said first and second rail assemblies being in said second path, with only the other one of said first and second rail assemblies being connected to the second cable.

Despite its many advantages, some room exists for attaining further improvements in this product. For example, the aircraft window has a porthole through which light enters the cabin. In addition to the window shade being movable up and down by a drive assembly to control the amount of light being blocked, its width is sized to be wider than that of the porthole by a certain lateral spacing so that the side edge of the window shade extends laterally past the porthole in order to block incoming light. If the lateral extension of the window shade beyond the porthole is small, some light will bleed around the side of the window shade. Thus, it is desirable to make the window shade as wide as possible relative to the porthole. However, since the width of the shell (Wshell) for the window assembly is a given dimension for each aircraft, the width of the window shade (Wshade) is limited by the width of the vertical drive channel (Wdc) through which the drive assembly moves (Wshade=Wshell−2Wdc). The wider is this drive channel, the narrower must be the window shade. Thus, one area for potential improvement is to make this drive channel of motorized window shade mechanism as disclosed in U.S. Pat. No. 6,186,211 narrower.

One embodiment disclosed in U.S. Pat. No. 6,186,211 has two window shades that can be selectively moved into position to block light. One window shade can be translucent while the other is opaque. Each shade has its own motorized drive mechanism. Both motorized drive mechanisms must fit within the small confines of an aircraft window. To accomplish this, the motorized window shade mechanisms as disclosed in U.S. Pat. No. 6,186,211 had the motors inserted in the rail attached to the bottom edge of the shade. Since the motors moved along with the rail as the shade was extended and compressed, a flexible conductive ribbon functioning as a power cable and moving with the motors was required to energize the motors. This cable required its own space in the drive channel within which to travel with the motors. It is desirable to eliminate the need for this cable and for the space it requires. In fact, this is one way for making the drive channel narrower. Also, installing the motors in the rail imposes severe size limitations on the motor, which makes it more difficult to find a suitable motor in terms of size, performance and price. Such an arrangement also makes the rail large, thereby increasing the stack height of the shade assembly, which is undesirable.

Furthermore, motorized window shades can experience motion even though they should be stationary while the drive motor is inactive, i.e. uncommanded motion. Such uncommanded motion can occur due to such factors as the weight of the shade and/or the compression pressure of the shade while the motor is deactivated. It is desirable to eliminate such uncommanded motion. SUMMARY OF THE INVENTION

These and other objects are attained in accordance with one aspect of the present invention directed to a motorized mechanism for operating a window shade for controlling the amount of light admitted through a window.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 9 is an exploded view corresponding to the window assembly as shown in FIG. 8, except that motorized drive mechanism 15 is not shown in section but rather in a side view.

Although window 1 can be any type of window set in any environment, the present invention is disclosed with particular applicability to an aircraft window. As shown in FIGS. 4 and 9, an aircraft window is typically contoured to fit the curvature of the particular aircraft body into which it will be installed. Window 1 has an inner pane 9 and an outer pane 11. A motorized drive mechanism 15 (see FIGS. 4, 5 and 9) is provided for operating window shades 5 and 7. Mechanism 15 is placed in shell 17 and is kept in place by a panel 19 which is attached to the shell. Inner pane 9 is secured by retainer 21 which is snap-fit into a slot (not shown) in panel 19. Outer pane 11 is secured by retainer 23 which is snap-fit onto a flange of shell 17. Thus, shades 5 and 7 are positioned within the interior space of the window between panes 9 and 11.

Shades 5 and 7 and some associated drive mechanism components are shown in FIG. 10. The shades are shown in their fully compressed form. At the bottom of shade 5 is a rail 25 which is comprised of a top cap 27, a bottom cap 29, and a channel 31. Caps 27 and 29 are configured so that they can be snap-fit onto channel 31 to secure them in place. Cap 27 is slipped through the bottom pleat of shade 5, and then it is snap-fit onto channel 31. This way the pleat is attached to rail 25. Thus, as rail 25 is moved, its movement produces extension or compression of shade 5. Cap 29 is decorative and is used to finish off the appearance of the window shade rail aesthetically.

An axle, or shaft, 33 is configured to be inserted into the through-hole in channel 31. As best shown in FIG. 3, the ends of axle 33 protrude from channel 31 so that they can carry gears 35 and 37. Gear 35, while positioned inside carrier 36, slides onto the end of axle 33 that has flat 39 on it. As the end of axle 33 passes through opening 34 in boss 34 a(see FIGS. 3, 5, 7 and 10) of carrier 36 to reach gear 35, carrier 36 is simultaneously mounted onto axle 33 along with gear 35. Gear 35 has a corresponding flat 41 so that it is locked to rotate together with the axle. Similarly, gear 37, while positioned inside carrier 38, is lockably mounted onto the other end of axle 33 so as to be rotatable therewith. For reasons that will become apparent below, gear 37 is a driven gear, and gear 35 is a passive gear. As gear 37 is driven, its movement will cooperate with rack 43 in shell 17 (described in detail below with respect to FIGS. 6 and 7) to move rail 25 up and down to compress and expand shade 5. Since passive gear 35 is coupled to driven gear 37 by axle 33, the two gears will turn together to produce smooth motion of rail 25 along the window without any twisting of the rail or binding of the gears on the rack that might otherwise occur.

Axle 53 is configured to be inserted into the through-hole in channel 51. The ends of axle 53 protrude from channel 51 so that they can carry gears 55 and 57. Gear 55, while positioned inside carrier 56, slides onto the end of axle 53 that has flat 59 on it. Gear 55 has a corresponding flat 61 so that both are locked to rotate together. Similarly, gear 57, while positioned inside carrier 58, is lockably mounted onto the other end of axle 53 so as to be rotatable therewith. For reasons that will become apparent below, gear 55 is a driven gear, and gear 57 is a passive gear. As gear 55 is driven, its movement will cooperate with rack 43 in shell 17 to move rail 45 up and down to compress and expand shades 5 and 7. Since passive gear 57 is coupled to driven gear 55 by axle 53, the two gears will turn together to produce the same smooth motion of rail 45 achieved for rail 25.

Turning now to FIG. 5, it shows motorized drive mechanism 15 along with shades 5 and 7. Rail 25 is shown along with carriers 36 and 38 mounted to the ends of axle 33 housed within rail 25. Similarly, rail 45 is shown with carriers 56 and 58 mounted to the ends of axle 53 housed within rail 45. Passing through carriers 36 and 58 is a loop of a Synchromesh cable 63 that cooperates with motor driven pulley 65 as part of a Synchromesh Cable Drive. Such a drive is available from Stock Drive Products. Synchromesh cable 63 has a straight center section made of a core bundle of braided stainless steel wires encased in a nylon jacket. Wound spirally around the nylon jacket is another section made of a core bundle of braided stainless steel wires encased in a polyurethane jacket. When the Synchromesh cable is placed on the pulley 65, the spirally wound cable section fits within and engages specially sized and configured helical grooves in the pulley, so that rotation of the pulley produces linear motion of the cable.

Cable 63 is stretched between the motor driven pulley 65 and cable tensioning assembly 67 (discussed in detail below with respect to FIGS. 11 and 12). A cable guard 105 (described below in detail in connection with FIGS. 13-15) is mounted adjoining cable 63 and pulley 65. Motor 69 turns pulley 65. Since cable 63 is meshed with the grooves in pulley 65, rotation of pulley 65 produces corresponding linear motion of cable 63.

Carrier 56 is a driven carrier because it is fixed to and driven by cable 63. As shown in FIG. 10, carrier 56 has a hole 71 in its end wall 73. (A good view of hole 71 is shown in FIG. 3 with respect to driven carrier 38). This hole 71 goes completely through carrier 38 to a similar opening (not shown) in the opposite end wall. Cable 63 is inserted through one of these openings and exits through the other one to pass completely through carrier 38. Cable 63 is affixed to carrier 56 by a set screw (not shown) inserted into tapped hole 74 (see carrier 38 in FIG. 3). Cable 63 then continues to carrier 36 which is a passive carrier because it is not affixed to cable 63. Instead, carrier 36 has an elongated channel 75 passing completely therethrough from one end to the other. Cable 63 runs freely through channel 75. Channel 75 can be curved, as is visible in FIG. 10, for example, to match the arc followed by cable 63.

In operation, motor 69 is used to extend and compress shade 7. As motor 69 is controlled to turn in a particular direction, depending on whether extension or compression of shade 7 is desired, and for a specific number of turns, depending on how much movement of shade 7 is desired, it drives pulley 65. In turn, rotation of pulley 65 generates linear motion of cable 63. Since carrier 56 is attached to cable 63, they both move together. As carrier 56 moves, and because its associated gear 55 is in mesh with rack 43, the gear 55 will turn along with axle 53. Rotation of axle 53 will cause rotation of gear 57 at the opposite end of the axle. Since gear 57 is in mesh with rack 43, both ends of rail 45 will move synchronously and smoothly to position the shade as desired. Thus, due to the cable 63 being fixed to driven carrier 56 but not to passive carrier 36, motor 69 drives only shade 7 and not shade 5.

Similarly, at the other side of the window shade assembly, cable 63 ais stretched between the motor driven pulley 65 aand cable tensioning assembly. Motor 69 aturns pulley 65 a. Since cable 63 ais meshed with the grooves in pulley 65 a, rotation of pulley 65 aproduces corresponding linear motion of cable 63 a. Cable 63 ais affixed to driven carrier 38. Cable 63 athen continues to passive carrier 58 which has the same structure as passive carrier 36. Passive carrier 58 is not affixed to cable 63 a. Cable 63 aruns freely through carrier 58.

In operation, motor 69 ais used to extend and compress shade 5. As motor 69 ais controlled to turn in a particular direction, depending on whether extension or compression of shade 5 is desired, and for a specific number of turns, depending on how much movement of shade 5 is desired, it drives pulley 65 a. In turn, rotation of pulley 65 agenerates linear motion of cable 63 a. Since carrier 38 is attached to cable 63 a, they both move together. As carrier 38 moves, and because its associated gear 37 is in mesh with rack 43, the gear 37 will turn along with axle 33. Rotation of axle 33 will cause rotation of gear 35 at the opposite end of the axle. Since gear 35 is in mesh with rack 43, both ends of rail 25 will move synchronously and smoothly to position the shade as desired. Thus, due to the cable 63 abeing fixed to driven carrier 38 but not to passive carrier 58, motor 69 adrives only shade 5 and not shade 7.

The motorized drive mechanism 15 is secured within window assembly 1 by retainers 77 and 77 a(which are mirror images of each other) at the side edges of shell 17, as shown in FIG. 4. FIGS. 6 and 7 illustrate the retainers in greater detail. Retainer 77 ahas a slot 79 notched into its side. Slot 79 is defined by front wall 81 and rear wall 83. Rack 43 is embedded into the front wall 81 to face slot 79. Carrier 38 rides within slot 79 and gear 37 meshes with rack 43. Cable 63 ais also visible in these drawings, as is boss 34 awith its opening 34 to receive axle 33.

Window assembly 1 also includes a manual override assembly 111 shown in FIGS. 16 and 17. This feature is provided so that the window shades can be operated even under conditions when electrical power is lost. Motor 69 has a hex-shaped drive shaft 113. Drive shaft 113 mounted in the housing comprised of lower housing 114 aand upper housing 114 b. Drive shaft 113 turns output shaft 115 via manual override assembly 111. Output shaft 115 has its pulley driving end drivingly coupled to pulley 65. The other end of output shaft 115 is also hex-shaped. Coupler 123 is slidably mounted on the hex-shaped ends of shafts 113 and 115 which adjoin each other. Spring 125 is under compression between shoulder 127 on the coupler and shoulder 129 on the bottom housing. Thus, spring 125 biases coupler 123 into its coupling position. In this position of coupler 123, rotation of motor drive shaft 113 will be transmitted to pulley 65 via shaft 115.

The manual override assembly 111 includes a vertical shaft 117 with a bevel gear 119 at its end which is in mesh with bevel gear 121 on output shaft 115. The top of shaft 117 has an opening 150 (see FIG. 18) that is shaped to receive a tool (not shown) that can be inserted and then used to manually turn shaft 117. As shaft 117 and, along with it, bevel gear 119 are turned, bevel gear 121 can turn shaft 115. However, as long as shafts 113 and 115 are coupled to each other, manual rotation of shaft 115 is prevented by motor 69. To avoid this hindrance, a slidable cover 131 is provided. The flared sides 152 of cover 131 slide on rails 154 and the upper surface 155 of upper housing 114 b. As can be appreciated from FIG. 18, the straight bottom edge 156 of flared side 152 engages under rail 154, while the top 158 rides on surface 155.

Cover 131 has a bottom skirt 133 that has a half-opening 135 through which shaft 115 passes. The wall of skirt 133 that defines opening 135 bears against coupler 123. As shown in FIGS. 16 and 17, cover 131 is in its static, rest position as spring 125 presses coupler to the right, and coupler 125 likewise presses the skirt to the right. Cover 131 has an upwardly extending wall 137 that can serve as a finger catch. Cover 131 can be moved manually to the left by hooking a finger against wall 137 and pushing against the force exerted by spring 125. This uncovers opening 150 in shaft 117 so that the turning tool can be inserted into it. With the tool in the opening, the cover 131 is prevented from returning to its rest position under the influence of spring 125. Thus, cover 131 stays in its displaced position until the turning tool is removed.

As cover 131 is moved to its displaced position, skirt 133 forces coupler 123 to slide off output shaft 115, thereby de-coupling shafts 113 and 115 from each other. This frees output shaft 115 to turn under turning forces applied by shaft 117 and gears 119, 121 without interference from motor 69.

Although the motorized drive mechanism 15 is disclosed as being motor actuated, the rest of mechanism 15 without the motors can also be highly useful. Motors 69 and 69 acan be replaced by a manual drive arrangement. It could be similar to the manual override assembly 111 as disclosed herein that would function as a permanent drive rather than as an override. However, other manually driven arrangements could also be applied to turn pulley 65 and move cable 63 so as to create linear motion for extending and compressing the shades.
