1. Field of the Invention
The present invention generally relates to a vehicle window interior shade assembly. More specifically, the present invention relates to a vehicle window interior shade assembly that includes two shades moveable from opposite sides of a window that mate together at approximately a central portion of the window thereby covering the window blocking sunlight and visibility.
2. Background Information
Most vehicles are provided with windows that are for the pleasure and comfort of passengers, and not specifically for driving visibility. Such windows typically allow sunlight to stream into the vehicle whether or not the passenger desires such light. Also some vehicles, such as vans and SUVs (sports utility vehicles) are provided with sunroofs or glass panels (windows) in the roof of the vehicle. In sunroofs, a slidable rigid panel is occasionally provided in the roof structure in order to provide shade and selectively cover the sunroof to block bright sunlight. However, such rigid panels require space between a headliner and roof structure of the vehicle, or are removable and require storage space elsewhere within the vehicle. Two examples of vehicles having a sunroof with a retractable window covering are disclosed in U.S. Pat. No. 6,682,133 and U.S. Pat. No. 6,899,380. Moreover, there are many aftermarket shade assemblies that are installable on vehicle windows to selectively block the sunlight. In particular, sun shades are available for covering windshields in order to keep the vehicle cool in bright sunlight conditions and protect portions of the dashboard and seats. Some examples of such windshield covers are disclosed in U.S. Pat. No. 5,101,878, U.S. Pat. No. 5,884,731 and U.S. Pat. No. 6,267,431. However, such shade assemblies are not typically intended for use while driving the vehicle. Also some of these shade assemblies are temporarily installed units that mount on a portion of the vehicle.
In view of the above, it will be apparent to those skilled in the art from this disclosure that there exists a need for an improved shade assembly that provides shade for vehicle windows and sunroofs in order to block bright sunlight. This invention addresses this need in the art as well as other needs, which will become apparent to those skilled in the art from this disclosure.
It has been discovered that it is often desirable to use a pair of oppositely retractable shades in order to block light through a window or sunroof. It has also been discovered that it is beneficial to have portions of the two shades contacting or overlaping one another when in a closed position.
One object of the present invention is to provide a vehicle window interior shade assembly with trim members that mate with one another in order to completely block passage of light through two shades covering a single window opening.
Another object of the present invention is to provide an attractive trim member that provides strength and rigidity to a leading edge of a shade and adds to the functionality of the shade.
Accordingly, in one aspect of the present invention, a vehicle window interior shade assembly includes a vehicle shade support structure, a first shade, a second shade, and a trim member. The vehicle shade support structure is configured for installation adjacent to a window opening. The first shade and second shades are movably coupled to the vehicle shade support structure to move between respective retracted positions and extended positions. The trim member is coupled to a first leading edge portion of the first shade and includes an elongated recess configured to releasably receive a second leading edge portion of the second shade to form a continuous shade structure when the first and second shades are in both in their extended positions.
These and other objects, features, aspects and advantages of the present invention will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses preferred embodiments of the present invention.
Referring now to the attached drawings which form a part of this original disclosure:
Selected embodiments of the present invention will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments of the present invention are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
Referring initially to
Each interior shade assembly 12 includes a support structure 13, a first rollup 14 and a second rollup 15. As described in greater detail below, the first and second rollups 14 and 15 are each supported by the support structure 13 to move between respective retracted or open positions and respective extended or closed positions. Further, the first and second rollups 14 and 15 are configured to interact with one another when in their respective closed positions to completely cover the window 11 thereby blocking light from shining therethrough. Specifically, each of the first and second rollups 14 and 15 includes a first shade 16, a second shade 18, a trim member 20 attached to a free end of the first shade 16 and a reinforcement member 22 attached to a free end of the second shade 18. As described in greater detail below, the trim member 20 and the reinforcement member 22 overlap or mate when the first and second rollups 14 and 15 are in their closed positions. Consequently, when in their closed positions, the first and second shades 16 and 18 together with the trim member 20 and the reinforcement member 22 of each of the first and second rollups 14 and 15 completely cover the windows 11 to block all light that would otherwise shine through the windows 11.
With specific reference to
The support structure 13 supports and confines movement of the first and second rollups 14 and 15 as the first and second rollups 14 and 15 are retracted into and pulled out of the take-up mechanisms 32. Specifically, one end (not shown) of the first shade 16 of the first rollup 14 is fixed to a conventional spring loaded spindle (not shown) within one of the take-up mechanisms 32. Similarly, one end (not shown) of the second shade 18 of the second rollup 15 is fixed to a conventional spring loaded spindle (not shown) within the other of the take-up mechanisms 32. The take-up mechanisms 32 are conventional structures that are well known, and thus, will not be discussed and/or illustrated in further detail herein. The rails 30 and the take-up mechanisms 32 are configured for installation to the vehicle 10 adjacent to the window 11 in a conventional manner, such as fasteners or clips. The cables C, the pulleys P and the motors 34 generally define a control mechanism for independently operating the first and second rollups 14 and 15 such that the trim member 20 and the reinforcement member 22 of each of the first and second shades 16 and 18 move independently from their open or retracted positions (
The rails 30 are preferably made of extruded aluminum or other rigid material. The rails 30 preferably have a U-shaped cross-section, as shown in
The take-up mechanisms 32 preferably operate as conventional shade retraction mechanisms that include the above mentioned spring biased spindle or shaft (not shown) about which the first and second shades 16 and 18 of the first and second rollups 14 and 15 are wound when in the retracted position. When pulled out of the take-up mechanisms 32 to their respective extended positions the first and second shades 16 and 18 of the first and second rollups 14 and 15 wind off the spindle or shaft as it rotates against the biasing of the spring (not shown). The biasing of the spring in each of the take-up mechanisms 32 urges the spindle or shaft to wind in a conventional manner drawing the first and second shades 16 and 18 about the spindle or shaft back into their respective one of the take-up mechanism 32.
The first and second rollups 14 and 15 are drawn to their extended or closed positions by respective ones of the motors 34 and corresponding ones of the cables C in the first embodiment. The cables C extend around corresponding pulleys P and connect to respective ends of the trim member 20 and the reinforcement member 22. Connections of the cables C to the trim member 20 and the reinforcement member 22 are described in greater detail below in the description of the trim member 20 and reinforcement member 22. The spring biasing arrangements in the take-up mechanisms 32 cause the first and second shades 16 and 18 of the first and second rollups 14 and 15 to retract when tension on the cables C is released by the motor 34 in a conventional manner.
It should be understood from the drawings and description herein, that the support structure 13 of the interior shade assembly 12 can have any of a variety of configurations. For example, in the depicted embodiment, two motors 34 control opening and closing (retracting and extending) of the first and second rollups 14 and 15. Specifically, one of the motors 34 controls the extending and retracting movement of the first rollup 14 and the other of the motors 34 independently controls the extending and retracting movement of the second rollup 15. Alternatively, a single motor 34 can used to control synchronous opening and closing of the first and second rollups 14 and 15. Further, in yet another configuration, the motor(s) 34, the pulleys P and the cables C can be eliminated and the first and second rollups 14 and 15 can be manually extended and retracted. In manually operated configuration, the spring biasing of the take-up mechanisms 32 is sufficient to draw the first and second shades 16 and 18 of the first and second rollups 14 and 15 onto the take-up mechanisms 32, but only when the first and second shades 16 and 18 are manually moved to the open or retracted positions.
The first and second rollups 14 and 15 are now described in greater detail below with specific reference to
As mentioned above, the second rollup 15 basically includes the second shade 18 and the reinforcement member 22. The second rollup 15 is also configured to move between the open position (
The first and second shades 16 and 18 are preferably made at least partially of a flat, flexible sheet-like material, such as textile or fabric, canvas, plastic or similar polymer material. The first and second shades 16 and 18 can be a single material or may be laminated materials. The first and second shades 16 and 18 include the side edges 36 (shown in
With specific reference to
The support portion 50 is preferably formed of a generally rigid or stiff material. The support portion 50 extends at least a width of the first shade 16 and further extends between the rails 30, as indicated in
The guide portion 52 basically includes an elongated recess 60 configured to releasably receive the leading end portion 28 of the second shade 18 to form a continuous shading cover when the first and second shades are in both in their extended positions (
The attachment portion 54 is defined on a side of the trim member 20 opposite from the guide portion 52. The attachment portion 54 basically includes an attachment groove 70. The attachment groove 70 preferably has cylindrical shape that extends lengthwise through the trim member 20 and a narrow slit 72 that extends lengthwise along the trim member 20. The first shade 16 extends through the narrow slit 72.
A retainer bar 74 is disposed within the cylindrically shaped attachment groove 70. The retainer bar 74 can be made of a plastic material, polymer material, metal material or any other suitable material for retaining the first shade 16 within the attachment portion 54 of the trim member 20. Further, the leading end portion 26 of the first shade 16 extends at least partially around the retainer bar 74. The first shade 16 is fixed within the attachment groove 70 of the attachment portion 54 of the trim member 20 by any of a variety of ways. For example, the leading end portion 26 of the first shade 16 can be wrapped around the retainer bar 74 and the retainer bar 74 can be force fitted within the attachment groove 70. In other words, friction retains the first shade 16 in the attachment groove 70 of the attachment portion 54 of the trim member 20. Alternatively, the leading end portion 26 of the first shade 16 can be fixed by adhesives to the retainer bar 74. Further, leading end portion 26 of the first shade 16 can be stapled or otherwise fixedly attached to the retainer bar 74.
As shown in
With reference to
The leading end portion 28 of the second shade 18 is at least partially wrapped around the reinforcement member 22. The leading end portion 28 of the second shade 18 can be fixed by adhesives to reinforcement member 22. Alternatively, the leading end portion 28 of the second shade 18 can be stapled or otherwise fixedly attached to the retainer bar 74.
The reinforcement member 22 is preferably made of a plastic or polymer material, but can alternatively be made of a metal material. The reinforcement member 22 is dimensioned to easily slide in and out of the recess 60 of the guide portion 52 of the trim member 20. Specifically, the reinforcement member 22 is dimensioned to have the same height or slightly smaller than the height of the recess 60. Each lateral end of the reinforcement member 22 includes side end projections 78, as shown in

The trim member 120 includes a support portion 150, a guide portion 152 and an attachment portion 154. The support portion 150 and the attachment portion 154 are generally the same as in the first embodiment. For instance, the attachment portion 154 is configured to retain the first shade 16 as in the first embodiment, and the guide portion 152 has a recess 160 that mates with the leading end portion 28 of the second shade 18 and the reinforcement member 22. Further, the trim member 120 and the first shade 16 are supported for movement along the rail 30, as in the first embodiment.
However, the guide portion 152 is configured differently from the first embodiment. Specifically, the guide portion 152 includes a pair of guide lips 166 and 168 either side of the recess 160 to guide the leading end portion 28 of the second shade 18 into the recess 160. The guide lips 166 and 168 are formed with diverging surfaces 180 and 182 that diverge in a direction extending away from the recess 160. The surface 180 is concaved relative to the lip 166 and the surface 182 is concaved relative to the lip 168. However, it should be understood from the drawings and the description that the surfaces 180 and 182 can diverge and yet be flat or slightly convex. The purpose of the surfaces 180 and 182 is to help guide the reinforcement member 22 attached to the second shade 18 of the second rollup 15 into the recess 160. With the diverging shape of the surfaces 180 and 182, any misalignment or off-centered positioning of the second rollup 15 with respect to the recess 160 is easily corrected, as indicated in phantom in
