The present disclosure relates to an anti-billow awning assembly and connection system, and more particularly, an assembly that secures an awning canopy cover to a structure in a retracted position that includes enhanced safety features over conventional awning systems.
An awning is a welcome addition to a house, recreational vehicle, or other dwelling. The awning typically provides increased enjoyment of an outdoor area surrounding the dwelling. The awning can cast a shaded area that creates an escape from direct sunlight, thereby providing a space in which an occupant of the dwelling may relax. The shaded area created by the awning contributes to the relaxation of the occupant in that there is a perceived decrease in temperature and, thus, generally becomes more comfortable. The awning as well advantageously protects occupants underneath from precipitation.
Known awning structures generally consist of a base that is permanently affixed to the dwelling, and a canopy that is removably attached to the base. Conventional awning structures are discussed in detail further in U.S. Pat. No. 6,971,433 assigned to Carefree/Scott Fetzer Company. U.S. Pat. No. 6,971,433 is incorporated herein by reference in its entirety for all purposes.
While awnings used on a home or recreational vehicle are opened and closed using a manual crank on a motor/switch, the slide-out canopy operates differently. The slide-out canopy is opened and retracted as the slide-out opens outward. Further details of the slide-out canopy operation are discussed in U.S. Pat. No. 7,017,976 assigned to Carefree/Scott Fetzer Company. U.S. Pat. No. 7,017,976 is incorporated herein by reference in its entirety for all purposes.

Now referring to
The awning canopy 26 comprises an inner or proximal edge 28 secured to a support rail 22 and an outer edge 30 secured to a support point 74 of an axle 75, illustrated in
In one example embodiment, the support system 36 may comprise one of two scissors-type arms 38 (that support the awning assembly 20 as shown in
In another example embodiment, such as illustrated in
As will be appreciated, as the roll bar 32 is extended in one or the other direction, such as by the motor, motors, or by the slide-out structure 23 going out from or into the support structure 24, the awning canopy 26 is rolled onto or unrolled from the axle 75 of the roll bar 32, causing the awning assembly 20 to retract or extend, respectively.
The rolling assembly 29, as illustrated in
In the illustrated example embodiment, the track assembly 58 comprises a rotatable connection 59 with the hub 31. For example, the track assembly 58 will not rotate while the hub 31, the roll bar 32, the axle 75, and in some conditions, the lock bearings or sprockets 52 rotate to unspool or spool the awning canopy 26. In an example embodiment, the rotatable connection 59 comprises a shaft 59A rotating through the track assembly 58, the shaft 59A forming a hub axle 59B fixed to the hub 31, and the lock bearing 52, as illustrated in
In the illustrated example embodiment, the rolling assembly 29 is in contact or coupled to, via the roll bar 32 and/or the track assembly 58, with an alignment component 17 at a contact point 15 (see
Responsive to a second force, over a force threshold, being applied to the awning canopy 26 and/or the role bar 32, the rolling assembly 29 is moved in a second direction 13B, along the track 54 via the track assembly 58, away from the alignment component 17. In one example embodiment, the second force is applied in a same direction as the second direction 13B. In another example embodiment, the force threshold comprises a force sufficient to cause the awning canopy 26 to unspool. The force threshold may be selected for by altering the force that the tension component 12 applies. The second force is, for example, generated by gusts of wind, or, such as when the awning assembly 20 is attached to a mobile structure, wind generated based on road dynamics, weather, and/or a speed of the mobile structure.
In the illustrated example embodiment, the lock bearing 52 is coupled to the rolling assembly 29, as illustrated in
The lock bearing 52 comprises a plurality of teeth 16 configured to interact with at least one of a plurality of locks 14 comprised on the end cap 35. In an example embodiment, a first lock 14A and/or a second lock 14B of the plurality of locks 14 comprises a protrusion extending out from the end cap 35. In an example embodiment, the protrusion protrudes at a substantially 90° angle from the end cap 15 toward the lock bearing 52.
Responsive to the second force, over the force threshold, being applied to the awning canopy 26 and/or the role bar 32, the rolling assembly 29 is moved in the second direction 13B, along the track 54 via the track assembly 58, such that at least one of the plurality of teeth 16 interlocks with at least one of the plurality of locks 14. The interlocking of at least one of the plurality of teeth 16 with at least one of the plurality of locks 14 comprises a locked mode of the rolling assembly 29, such as illustrated in
The plurality of teeth 16 and the plurality of locks 14 are configured to be free from interaction when the tension component 12 is maintaining the rolling assembly 29 in an unlocked mode, as illustrated in
The rolling assembly 29 and the lock bearing 52 are present in one of a first end cap 35A, a second end cap 35B, or both. For example, the first end cap 35A houses the rolling assembly 29 and the lock bearing 52, and the second end cap 35B houses a standard hub 31, connected to the roll bar 32. The standard hub 31 merely rotates to spool or unspool the awning canopy 26. In another example embodiment, as illustrated in
In an example embodiment of the locked mode, as illustrated in
During operation, the biasing member 12 biases the rolling assembly 29 to an unlocked condition, and thus, the hub 31, track assembly 58, the axle 59, roller bar 32, lock bearing or sprocket 52, and canopy 26 can rotate in either a first direction or second direction. In this unlocked condition, the hub 31, track assembly 58, the axle 59, roller bar 32, lock bearing or sprocket 52, and canopy 26 can unwind or unspool from the roller bar or be wound or spooled back onto the roller bar 32, either manually or assisted by the motor located within the end caps 35 or on the awning assembly 20.
Under certain operating conditions, forces overcome the biasing member 12, allowing the track wheel assembly 58 of the rolling assembly 29 to translate smoothly to a locked position, and thus, the hub 31, track assembly 58, the axle 59, roller bar 32, lock bearing or sprocket 52, and canopy 26 to a locked position where the canopy cannot unwind or unspool from the roller bar along one of a clockwise or counterclockwise direction. In the locked position, the teeth 16 prevent rotation of the sprocket 52 because they engage a lock 14. In one example embodiment, the lock 14 is includes a ramp in one direction and an abutment in another direction, and the lock and teeth of the sprocket are coplanar. As such, rotation of the sprocket 52 in a first direction causes the teeth to engage the abutment face of the lock, thus preventing rotation of the sprocket 52. While rotation of the sprocket 52 in a second direction, opposite the first direction, the teeth 16 engage the lock 14 ramp, allowing rotation of the sprocket in a the second direction.
In the illustrated example embodiment, the rolling assembly 29 comprising the hub 31, track assembly 58, the axle 59, roller bar 32, lock bearing or sprocket 52, and canopy 26 are all interconnected such at rotation of one member results in the rotation of all other members. Further, the track assembly 58 comprise first and second wheels 56A and 56B, respectively that allow the translation of the roller assembly between a locked and unlocked position via tracks 54 spaced about the wheels in which the track assembly translates by the biasing member 12 or when forces overcome the biasing member.
When the rolling assembly 29 is in the locked position, wind dynamics, bumps, and road conditions advantageously no longer permit the awning canopy 26 from billow or unspool suddenly. Unspooling or billowing during driving may create a hazardous condition prevented by the anti-billow awning assembly 20 as described above. Wind or bumpy road conditions will now drive the roller assembly 29 into the locked condition stopping the unspooling of the awning by the locks preventing rotation in the unspooling direction. When the wind event or bumpy conditions cease, the roller assembly 29 is assisted by gravity and/or the biasing member 12 into a normal operating condition. The current design of the anti-billowing awning further advantageously no longer requires any interface with the wall of the recreational vehicle, eliminates any reliance on proper installation, unlike conventional awnings that require installers to properly adjust bolts to have the correct extension, and the anti-bellow design provides a clean appearance with no external components.
