Description

BACKGROUND

The embodiments herein relate generally to shades or cover devices used to block sunlight from entering through a vehicle's windshield.

A variety of covers have long been developed to serve as barriers to heat energy and/or to direct exposure to infrared, ultraviolet (“UV”), and visible portions of the solar spectrum. Methods of deploying these covers have likewise been developed to facilitate deployment and increase effectiveness. However, various concerns relating to conventional covers remain in the art.

In automotive settings, for example, inside cover designs are typically deployed manually, thereby requiring the presence of an occupant. Where an occupant is not present, the cover cannot be deployed. As a result, excessive temperature rise (and direct exposure of interior surfaces to solar radiation) in parked vehicles due to solar energy passing through glazing often occur rapidly, resulting at least in an unpleasant situation upon vehicle entry and more rapid degradation of UV sensitive interior materials.

Similarly, outside sunshades that typically overlay an entire glazing region, such as the front or rear windshield of a vehicle, have long been utilized to block the infiltration of radiant heat energy from the sun. Concerns remain here as well, as the manual deployment and stowing of these larger shades take even more time, are inconvenient, and when not in use require significant storage space.

More recently, vehicle covers having automatic deployment mechanisms have also been developed to reduce operation time and operator contributed energy. The electro-mechanical motors involved therewith, however, present their own concerns related to increased weight, volume, cost, noise, and likelihood of failure. Moreover, these types of mechanisms further present concerns related to up-keep, repair and replacement, as well as the establishment of an additional battery load.

As such, there is a need in the industry for a universal automated shade for a vehicle's windshield, which overcomes the limitations of the prior art.

SUMMARY

An automated shade apparatus detachably coupled to a windshield of a vehicle and configured to deploy or retract with enhanced efficiency is provided.

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS

As depicted in FIGS. 1-4, shade apparatus 10 is configured to be secured to windshield 64 of vehicle 62 to block sunlight from entering the interior of the vehicle. Vehicle 62 may be any type of automobile such as a car, bus, truck, or the like, which includes steering wheel 66 and dashboard 68.

In a preferred embodiment, a pair of shade apparatuses 10 is detachably coupled to portions of windshield 64 near the top edge. In one embodiment, a first shade apparatus 10 is secured to a left portion of windshield 64 and a second shade apparatus 10 is secured to a right portion of windshield 64. It shall be appreciated that any alternative number of shade apparatuses may be used instead.

Each shade apparatus 10 generally comprises housing 12, cover 14, belt 20, motor 32, retractable sheet 34 and scissor arms 38. As will be apparent in the following detailed disclosure, scissor arms 38 are operably connected to belt 20, motor 32 and retractable sheet 34. Retractable sheet 34 is rotatably mounted to housing 12 via shaft 36 such as a drum roll, which may be spring-loaded. In one embodiment, shaft 36 is a hollow tube that is configured to roll and dispense retractable sheet 34 as desired. Retractable sheet 34 may be any type of material known in the field such as fabric.

Motor 38 is configured to compress scissor arms 38 to retract retractable sheet 34 as depicted in FIG. 1 or extend scissor arms 38 to deploy retractable sheet 34 as depicted in FIG. 2. In the retracted configuration, windshield 64 is exposed and unobstructed for a driver (not shown). In the deployed configuration, the majority of windshield 64 is covered to block the entrance of sunlight into vehicle 62, including infrared, ultraviolet and visible portions of the solar spectrum.

As depicted in FIGS. 4 and 6, adhesive members 56 are coupled to housing 12 and are configured to detachably couple shade apparatus 10 to windshield 64. In a preferred embodiment, threaded screw 60 is disposed through a wall of housing 12 as depicted in FIG. 7. This permits a user (not shown) to rotatably adjust threaded screw 60 until the tip is in contact with windshield 64. This ensures shade apparatus 10 remains stable when adhered to windshield 64 during its operation. Any gap between shade apparatus 10 and windshield 64 is eliminated since threaded screw 60 contacts the windshield.

As depicted in FIGS. 8-9, housing 12 comprises a compartment configured to store belt 20, belt rollers 18 and belt roller shafts 22. Belt rollers 18 are situated on opposing ends of housing 12. Motor 32 is operably connected to one of the pair of belt rollers 18 and may comprise any mechanical components such as gears as known in the field. Motor 32 is configured to drive belt roller 18 to permit belt 20 to travel around the pair of belt rollers 18 in first direction or a second direction opposite the first direction. Motor 32 may be powered by a power source such as a battery (not shown). In one embodiment, circuit board 58 is disposed within housing 12 and is operably connected to motor 32 as shown in FIG. 6. Circuit board 58 controls the operation of motor 32.

Scissor arms 38 comprise a plurality of arm members pivotably connected to each other by connecting screws at first pivot point 40, second pivot point 42, third pivot point 44 and fourth pivot point 46. The connecting screws at pivot points 40, 42, 44, 46 permit scissor arms 38 to easily extend and collapse as needed. As depicted in FIG. 5, bottom scissor arm pivot points 52, 54 are coupled to the bottom of retractable sheet 34. More specifically, base bracket 48 is coupled to the bottom of retractable sheet 34 and comprises a pair of base bracket slots 50. Bottom scissor arm pivot points 52, 54 are disposed within base brackets slots 50 and are configured to slide horizontally therein as scissor arms 38 extend and collapse.

As depicted in FIGS. 8-9, upper scissor arm pivot points 26, 30 are connected to belt 20 by lower carriage attachment 24 and upper carriage attachment 28. Upper carriage attachment 28 is coupled to upper belt portion 84 and lower carriage attachment 24 is coupled to lower belt portion 86. In one embodiment, carriage attachments 24, 28 may be linear bearings. However, any alternative mechanical fasteners can be used to secure scissor arm pivot points 26, 30 to belt 20. Cover 14 of shade apparatus 10 comprises cover slots 16, which permit upper scissor arm pivot points 26, 30 and carriage attachments 24, 28 to slide horizontally therein as scissor arms 38 extend and collapse.

In operation, shade apparatuses 10 are installed to windshield 64 as shown in FIG. 1. Motor 32 is activated via a switch (not shown) to drive belt 20 in a first direction or a second direction as shown in FIG. 10. When drive belt 20 travels in a first direction, carriage attachments 24, 28 and upper scissor arm pivot points 26, 30 slide horizontally toward each other. This extends scissor arms 38, which deploys retractable sheet 34 as shown in FIGS. 2 and 5. When drive belt 20 travels in a second and opposite direction, carriage attachments 24, 28 and upper scissor arm pivot points 26, 30 slide horizontally away from each other. This collapses scissor arms 38, which retracts retractable sheet 34 as shown in FIG. 1.

As depicted in FIG. 11, operator 72 may control the operation of any number of shade apparatuses 10 via remote control device 70. Remote control device 70 is configured to communicate with circuit board 58 of each shade apparatus 10 to deploy and retract retractable sheet 34 as needed. In an alternative embodiment, operator 72 may control the operation of shade apparatus 10 manually by a switch (not shown) on motor 32.

As depicted in FIG. 12, one or more extension members 74 may be coupled to retractable sheet 34 by any fastening components known in the field. Extension member 74 is preferably a retractable sheet disposed around a shaft such as a drum roll, which is spring-loaded. Extension member 74 may have variable dimensions and is configured to be secured to either the left or right sides of retractable sheet 34. Extension member 74 is beneficial because it covers any additional exposed areas on windshield 64 omitted by retractable sheet 34. Since each extension member 74 is coupled to retractable sheet 34, extension member 74 deploys and retracts when retractable sheet 34 deploys and retracts.

Several design modifications can be made to shade apparatus 10. In an alternative embodiment, retractable shade roller 82 is secured to windshield 64 as shown in FIG. 13. Retractable shade roller 82 is disposed around hollow rod members 76, which can be spring-loaded by spring 80. Alternate DC motor 78 is operably connected to one of hollow rod members 76 and is configured to rotate the rod member in a first direction or a second direction as needed, thereby deploying or retracting retractable shade roller 82 as desired. FIG. 14 depicts retractable shade roller 82 in the deployed position. This alternate configuration of a shade apparatus removes the need for scissor arms 38, and is therefore a more simple design.

It shall be appreciated that the shade apparatuses described herein provide a barrier against the effects of the sun by completely covering a vehicle's windshield or rear windshield to prevent or reduce sunlight from entering and degrading interior components made of fabric, leather or polymers. Further, the shade apparatuses may restrict the generation of heat in the interior of a vehicle, thereby reducing the ambient temperature for efficient functioning of air conditioning, cooler seats and steering wheel, etc., and reduce the “oven” effect in summer and hot weather conditions.

It shall be appreciated that the components of the shade apparatuses described in several embodiments herein may comprise any known materials in the field and be of any color, size and/or dimensions. It shall be appreciated that the components of the shade apparatuses described herein may be manufactured and assembled using any known techniques in the field.

Persons of ordinary skill in the art may appreciate that numerous design configurations may be possible to enjoy the functional benefits of the inventive systems. Thus, given the wide variety of configurations and arrangements of embodiments of the present invention the scope of the invention is reflected by the breadth of the claims below rather than narrowed by the embodiments described above.
