This invention relates generally to roll-up awnings, and in particular to awnings used for buildings, travel trailers, or recreational vehicles, and specifically to an awning roller assembly with a self-contained power source and a motor embedded within a roll-up tube for deploying and retracting the awning.
It has long been recognized that roll-up awnings are useful in the recreational vehicle field, as well as for homes and businesses. Such awnings are particularly useful when trailer homes or recreational vehicles are parked at a campsite. While parked, there is a need for a protected area in which users may take cover from the sun or inclement weather. A spring-biased, roll-up awning has long been used in the field.
A roll-up, retractable awning generally comprises either a canopy connected at one edge to the wall of a building or recreational vehicle, and at the opposite edge connected to a roller tube, or a roll-up tube fixed to the side of the wall with the edge of the canopy connected to a horizontal rod connected to support arms. For the fixed roller tube, the support arms may be spring-loaded so that the arms extend the end of the canopy outward when the canopy is deployed. For the non-fixed tube design, the roller tube is typically pivotally supported by extended support arms which are pivotally mounted to the wall. In both designs, in a stowed position, the canopy is rolled about the roller tube and secured to the wall.
In the deployed position, the support arms must not only support the weight of the canopy, but also the weight of other attachments (such as a screen or a valance and perhaps any motors), as well as resist the forces of nature (such as wind and rain).
As described above, retractable awnings may have either a stationary roller tube mounted to the wall, or a roller tube that is extended outward by the support arms. When not deployed, the awning canopy is typically rolled around the tube for storage and, if used on a vehicle, for travel.
Retractable awnings can be manually operated, or they may utilize a motor to make extension and retraction automated and quicker. The motor may positioned on one of the arms, outside the roll tube, or as disclosed in application Ser. No. 10/237,912, filed on or about Nov. 9, 2002, incorporated herein by reference. According to that reference, the motor may be partially or fully inserted into the roll-up tube. This can protect the motor from the elements, and allow a wider awning canopy that might be possible using an arm-mounted motor. Further, an in-the-tube motor can be more aesthetically pleasing to the user.
However, a motor-operated awning requires that power of some sort be provided to the motor. A motor could be electrically powered or hydraulically powered, for example. Hydraulically powered awnings typically require an electrical power supply to drive a compressor. Thus, electrical power is typically necessary for a powered awning of any type.
Because electrical power is necessary for a powered awning, retrofit awnings often require that the wall of the building or vehicle for mounting the awning be penetrated for electrical wires to be installed and connected to the vehicle or building electrical system. This can expose the wall and the interior to the elements and it will destroy the integrity of the wall (especially an issue if the awning is removed). Further, such installation may require excessive installation labor, and leads to potential failure points. Thus, a self-powered awning that need not be connected to the vehicle or building electrical supply would be beneficial.
Further, an awning operated on a vehicle might require the running of a noisy and polluting generator, irritating the user and nearby individuals, or it might require the use of the vehicle's power supply to power the awning, thus running the risk of depleting a vehicle battery. Thus, some other means of powering the awning would be useful to avoid these problems.

The embodiment of
The awning of
The alternative embodiment of
The deployment of the embodiment of
The awnings of either
In the embodiment of
For the embodiment of
For both embodiments, the one or more solar panels 34, each of which likely contain a plurality of solar cells, are positioned so that they can receive sunlight or other ambient light whether or not the awning is deployed. The rechargeable battery 32 may be directly connected to the solar panel(s) 34, or some voltage adapting circuit may be transposed between them to condition the voltage output of the solar panel(s) 34 to be compatible with the rechargeable battery 32. Further, protection circuits may be utilized in order to avoid overcharging the rechargeable battery, or improperly reverse biasing the solar panels.
Also for both embodiments, the rechargeable battery 32, alone or in combination with the solar panel(s) 34, is used to power the motor of the awning 1 for either deploying or retracting the awning, or both. Further, the combination of the rechargeable battery 32 along with the solar panel(s) 34, allows the awning to be retro-fitted to the wall 2 without requiring wiring the awning to an external power supply. Accordingly, the awning can be self-contained and self-powered, reducing installation time and avoiding any need to wire the awning to the building or vehicle power supply, as the case may be. Further, no unsightly or harmful penetration of the wall is necessary for running electrical wires, and thus the awning can be removed from the wall with less damage or other impact to the wall itself.
The primary adaptations for the awning of
A control unit (not shown) can also be provided for either embodiment in order to control the deploying and retracting operations of the awning, by controlling the motor of the drive assembly. The control unit will control the operation of the motor, allowing a user to turn the motor on and off, and control the direction of the motor, thereby deploying and retracting the awning. The control unit could be incorporated into the conduit 35, the battery 32, or be interposed between them. Alternatively, the control unit might be mounted elsewhere, and the control wires routed is some fashion (such as through the conduit 35) to the drive assembly 36.
Alternatively,
During assembly, the motor assembly 50 portion of the drive assembly 36 is at least partially, and can be mostly or fully, inserted into the roll-up tube 10 up to the end support cap 56. The motor assembly 50 is inserted into the roll-up tube 14 at the time of assembly with the end support cap 56 connecting to an end of the roll-up tube 14, providing physical support to the roll-up tube 3. The notches 58 of the disc 52 mate with projections 59, projecting from the interior of the roll-up tubes 14/24. The end support cap 56 connects to, and rotates along with, the roll-up tube 14/24 when the awning is being deployed or retracted.
In the embodiment of
In the embodiment of
The support arm mounting assembly 60 used in the awning of
Upon assembly of the awning, the motor assembly 50 is fully, mostly, or at least partially, inserted into the roll-up tube 14/24 sufficient that the notches 58 of the disc 52 at least partially engage the projections 59 shown on the interior of the roll-up tube 14 (and also on the tube 24, not shown). It is expected that as much of the motor assembly 50 as possible will be inserted into the tube to help protect the motor and for aesthetic reasons. However, it is also expected that circumstances may arise whereby some portion of the motor assembly may remain outside of the tube, such as situations where there is some gap between the roll-up tube assembly and a mounting arm.
By operating the motor in one direction, the awning can thus be made to deploy by causing the roll-up tube to unroll the canopy, whereby the arms will extend the awning and keep the canopy taught. By operating the motor in an opposite direction, the awning can be made to retract by winding the canopy upon the roll-up tube, causing, the awning to be pulled toward the support wall, and thus retracting the awning.
In the embodiment of
Further, manual means of operating the awning may also be provided in case of failure of automatic deploying/retracting means, or if the power supply is drained.
As discussed above, the invention can be used to retrofit an existing awning for automating the deployment and retraction of the awning and/or for embedding much of the motor assembly into the roll-up tube, without requiring the awning to be wired to the vehicle or building electrical system. The invention can also be used for installation on an existing vehicle or building, without requiring connection to the building or vehicle electrical system.
