DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS
Certain terminology is used herein for convenience only and is not to be taken as a limitation on the present invention. Further, in the drawings, the same reference numerals are employed for designating the same elements.
FIG. 1 depicts an awning assembly 100 for mounting to a support structure. Awning assemblies herein may be mounted to a wide range of support structures such as a vertical surface (e.g., a wall of a building, a wall of a mobile unit, a doorway or the like). In further examples, the support surface may comprise surfaces other than vertical surfaces (e.g., a ceiling, roof structure, etc.) or other support surfaces. In the illustrated example, the awning assembly 100 is shown mounted to a support structure 600 comprising a vertical wall of a recreational vehicle although other support structures may be provided in further examples. Awning assemblies herein may be used to shelter an area from falling debris, weather (e.g., sun, precipitation) and/or may be incorporated as part of an enclosure to inhibit contact with pests such as mosquitoes or the like.
The illustrated awning assembly 100 incorporates a variety of aspects of the present invention that may be used individually or in combination with one another. For instance, as shown, the awning assembly 100 can comprise at least one arm assembly 110 including a first segment 120 and a second segment 130 pivotally connected to the first segment. The first and second segments can comprise similar or different constructions with similar or different lengths depending on the particular application. As shown, the segments 120, 130 comprise linear segments although it is contemplated that the segments may be curved or have other shapes in different examples.
The second segment 130 can be pivotally connected to the first segment 120 in a wide variety of ways. For example, as shown in FIGS. 8, 10, 12 and 16, a pivot structure can be provided with a first pivot member 122 attached to the first segment 120 and a second pivot member 124 attached to the second segment 130. In some examples, there is no elevational angle between the first and second segment 120, 130. Alternatively, as shown in FIGS. 10 and 16, the first and second pivot member 122, 124 may be designed to provide an elevational angle between the first and second segments 120, 130. If provided, the elevational angle can comprise a wide range of angles depending on the particular application. For instance, an elevational angle between the first and second segments 120, 130 of from greater than 0° to approximately 45° can be provided. In further examples, an elevational angle between the first and second segments 120, 130 of from greater than 3° to approximately 20° can be provided. In still further examples, an elevational angle between the first and second segments 120, 130 of about 5° or about 12° can be provided. While optional, providing an elevational angle between the first and second segments may be desirable to help position a sheet of flexible awing material 102 above portions of the first and second segments as shown in FIG. 1.
The at least one arm assembly 110 can further include a biasing member 140 extending between portions of the first and second segments 120, 130. In some examples, the first and second segments 120, 130 are configured to pivot relative to one another between an open orientation (see FIGS. 8 and 10) with the biasing member 140 being exposed and a closed orientation (see FIG. 9) with the biasing member being substantially hidden within an area defined by the first and second segments 120, 130. The area that hides the biasing member 140 in the closed orientation can be defined entirely by one of the first or second segment with the other of the first and second segment acting as a cover for the area. Alternatively, as shown, the area that hides the biasing member 140 in the closed orientation can be defined by portions of the first and second segment. Moreover, the first segment, second segment, and/or the biasing member 140 may be configured to facilitate the closed orientation illustrated in FIG. 9. For example, as shown in FIGS. 8 and 9, the second segment 130 may include a male lip portion 132 configured to fit within an interior area or a female groove of the first segment 120 to allow an enhanced fit between the segments in the closed orientation. In further examples, the biasing member 140 may include an alignment structure 142 configured to align the biasing member 140 within the first segment 120 as the first and second segments are moved between the open orientation and the closed orientation. The alignment structure 142, for example, can comprise a ring of material configured to extend around the biasing member 140 to provide a thickness of material on the sides of the biasing member that face interior surfaces of the first segment 120. As the first and second segments are moved to the closed orientation, the ring of material will tend to align the biasing member 140 within the interior area of the first segment 120.
The biasing member 140 can comprise a wide range devices configured to bias the first and second segments 120, 130 to the open or closed orientation. In the illustrated example, the biasing member 140 is configured to bias the first and second segments 120, 130 to the open orientation although it is contemplated that further examples may include a biasing member that biases the first and second segments to the closed orientation. Furthermore, the biasing member may be constructed from a wide range of devices. For example, the biasing member can comprise a coil spring or other biasing mechanism. In the illustrated example, the biasing member 140 comprises a gas spring with a first end 140a attached to a portion of the first segment 120 and a second end 140b attached to a portion of the second segment 130.
A wide range of structures may be used to attach the ends of the biasing member 140 to the respective segments. For example, as shown in FIG. 15, the first end 140a of the biasing member 140 may be attached to the first segment 120 by a first attachment bracket 144. Likewise, as shown in FIG. 16, the second end 140b of the biasing member 140 may be attached to the second segment 130 by a second attachment bracket 146. The attachment brackets 144, 146 can be adjustably attached to the respective first and second segments 120, 130. For example, the brackets may be attached at alternative locations along the length of the respective segments to allow an appropriate precompression of the biasing member 140 depending on the particular application.
In examples of the present invention, the arm assembly 110 can be attached between the support structure 600 and a lead rail 220. As shown in FIGS. 4-7, an arm mount assembly 148 may be used to mount the arm assembly 110 to a back cover 400 which may be, in turn, attached to the support structure 600. As shown in FIGS. 6 and 7, the arm mount assembly 148 may comprise a mounting bracket 150 configured to mount to a support structure. As shown, the mounting bracket 150 is configured to mount indirectly to the support structure 600 by way of the back cover 400. Although not shown, it is contemplated that the mounting bracket may also be configured to mount directly to the support structure.
The arm mount assembly 148 can also include a link member 160 pivotally attached between the arm assembly 110 and the mounting bracket 150. As shown, the arm assembly 110 is configured to pivot with respect to the link member 160 about a first pivot axis 170 and the link member is configured to pivot with respect to the mounting bracket about a second pivot axis 180. Although not required, as shown, the first and second axis 170, 180 may be substantially perpendicular with respect to one another. As shown in FIG. 6, a pivot device 162 may be attached to a first end portion 112 of the arm assembly 110 such that the arm assembly may pivot with respect to the link member about the first pivot axis 170. As further illustrated in FIG. 6, the link member 160 may be pivotally attached to the mounting bracket 150 by way of a pivot bolt 152 extending through a bore of the mounting bracket 150 and link member 160 at attached by way of a nut 154 at the end of the pivot bolt 152.
As further illustrated in FIGS. 6 and 7, the mounting bracket 150 may be provided with a mounting shim 156 configured to fit within a lower portion 158a of a groove 158 of the mounting bracket 150. A pair of set mounting screws 157a, 157b are configured to press against the mounting shim 152 to attach the mounting bracket 150 to the back cover 400. As is apparent in FIG. 7, to mount the mounting bracket 150 to the back cover 400, the groove 158 of the mounting bracket 150 may be inserted over a tongue portion 402 of the back cover 400. Next, the mounting shim 156 may be inserted in the lower portion 158a of the groove 158 to provide an interlock between the mounting bracket 150 and the back cover 400. Next the mounting screws 157a, 157b can be tightened to attach the mounting bracket 150 to the back cover 400.
The arm mount assembly 148 can also include a structure configured to limit a rotation of the link member 160 with respect to the mounting bracket 150 about the second pivot axis 180. For example, as shown in FIGS. 6 and 7, a stop device 210, such as the illustrated stop screw, may be threaded through a bore 164 in the link member 160 to act against a shoulder 155 of the mounting bracket 150. As shown in FIG. 7, the stop device 210 can limit a clockwise pivot 182 of the arm assembly 110 about the second pivot axis 180 due to the weight of the arm assembly and structures supported by the arm assembly.
Still further, the arm mount assembly 148 can include a biasing member 202 further configured to resist rotation of the link member 160 with respect to the mounting bracket 150 about the second pivot axis 180. An insert portion 204a of a bearing pin 204 may be inserted into an end portion 202a of the biasing member 202. The end portion 202a, together with the bearing pin 204, may then be inserted in a bore (not shown) in the back of the link member 160. As shown in FIG. 7, the biasing member 202 presses against the back cover 400 below the second pivot axis 180. Referencing FIG. 7, it will therefore be appreciated that the biasing member 202 is configured to provide a reactive moment force in a counterclockwise direction about the second pivot axis 180 to counter the tendency of the pivot link to rotate about the second pivot axis 180 in the clockwise direction 182 due to the weight of the arm assembly 110 and structures supported by the arm assembly. The biasing member 202 can comprise a wide range of structures. As shown, the biasing member 202 can comprise a compression spring although it is contemplated that a resilient piece of rubber, leaf spring, or other biasing mechanism may be used in further examples. In still further examples, an adjustment device 200, such as the illustrated adjustment screw, may be provided and configured to adjust the compression of the biasing member 202. As shown, the adjustment device 200 may be threaded through a bore 166 and thereafter tightened to press against the bearing head 204b to increase the reactive moment force or loosened to decrease the reactive moment force. Providing an adjustment device 200 may therefore allow a user to fine tune the awning assembly 100 to accommodate different environments, or to adjust the device to accommodate different loads.
As mentioned previously, the arm assembly 110 may be attached between the support structure 600 and the lead rail 220. As discussed above, the arm mount assembly 148 may be used to mount the first end portion 112 of the arm assembly 110 to the support structure 600 by way of the back cover 400. In one example, as shown in FIGS. 4, 8, 10, 13 and 17, a lead rail pivot bracket 222 may be used to pivotally attach a second end portion 114 of the arm assembly 110 to the lead rail 220.
As shown in FIG. 4, the awning assembly 100 can further include a roller tube 410 for mounting with respect to the back cover 400. A top cover 420 can be placed over the back cover 400 in order to house the roller tube 410 and sheet of flexible awning material 102 that may be selectively rolled onto the roller tube 410. A motor may be housed within the roller tube with electrical contacts 412 extending from the roller tube 410 to connect with a control mechanism to control the deployment and retraction of the awning assembly 100. As shown in FIG. 3, the sheet of flexible awning material 102 is shown exploded from the remaining portions of the awning assembly. One end of the awning material 102 may be attached to the roller tube 410 while the other end of the awning material 102 may be engaged with a portion of the lead rail 220. Once attached to the lead rail 220, a pair of lead rail end brackets 224a, 224b may be used to secure the corresponding end of the awning material 102 with respect to the lead rail 220. As shown in FIG. 5, the back cover 400 may also be provided with one or more optional bumpers 404 configured to interact with each arm assembly 110 when the arm assembly is in a closed orientation. In the closed orientation, a surface of the first segment 120 will contact the bumper member 404 to help position the first segment 120 with respect to the back cover 400. Optional foam material members 406 may also be provided to help prevent scratching of the arm assembly 110 in the closed orientation.
In certain applications, the at least one arm assembly 110 of the awning assembly 100 may have a single arm assembly. As shown, it is also possible for the at least one arm assembly 110 to comprise two arm assemblies 110a, 110b although three or more arm assemblies may be incorporated in further examples. Providing two arm assemblies may be desirable to provide support at each end of a lead rail 220. Although the arm assemblies may be different from one another, the illustrated arm assemblies may be designed as substantial mirror images of one another.
If a plurality of arm assemblies are provided, they may be arranged in a wide variety of orientations. For example, as apparent in FIG. 3, the pivot connection between the first segment 120 and the second segment 130 of each arm assembly 110a, 110b will be closer together in the closed orientation than in the open orientation. Arranging the first and second arm assemblies 110a, 110b in this manner may be beneficial to allow appropriate spacing of the arm assemblies to provide support at each end of the lead rail 220 in the open orientation while also allowing the arm assemblies to fold in a compact manner when the arm assemblies are positioned in the closed orientation.
The awning assembly 100 may also be provided with one or more support legs attached to the lead rail 220 to provide supplemental support for the lead rail 220 when the arm assembly 110 is positioned in the open orientation. In one example, the support legs can be configured to engage a ground surface underneath the lead rail. In further examples, the support legs may be pivoted back to engage with the support structure 600. The support legs may be attached to the lead rail in a pivoting manner and may be designed to fold up into the lead rail in a stowed position. A pivot assembly 500 may be used to facilitate movement of the support leg from a deployed position to a stowed position.
The pivot assembly 500 can comprise a wide range of configurations to permit the first support leg 230 to be pivotally connected to the lead rail 220 such that the first support leg 230 can pivot to the stowed position with respect to the lead rail 220. FIGS. 20-24 illustrate aspects of one example of a pivot assembly 500 incorporating aspects of the present invention. As shown, the pivot assembly 500 can include a pivot bracket 510 that can include apertures 512 to attach the pivot bracket 510 to the lead rail 220. Rather than apertures, the pivot bracket 510 may be simply tack welded, glued, or otherwise connected to the lead rail 220. The pivot assembly 500 can also include a pivot arm 520 pivotally attached to the first support leg 230 to permit the first support leg 230 to pivot about a first axis 522 in a first direction. The pivot assembly 500 can further include a pivot link 530 pivotally attaching the pivot arm 520 to the pivot bracket 510. The pivot arm 520 can be configured to pivot with respect to the pivot link 530 about the second axis 532 extending in a second direction that is substantially perpendicular to the first direction. The pivot link 530 can still be further configured to pivot with respect to the pivot bracket 510 about a third axis 534 extending in a third direction that is substantially perpendicular to the first direction 522 and the second direction 532. In further examples, the pivot assembly 500 can include a first stop member 536 configured to limit the extent to which the pivot link 530 can pivot with respect to the pivot bracket 510. In addition or alternatively, the pivot assembly 500 can further include a second stop member 524 configured to limit the extent to which the pivot arm 520 can pivot with respect to the pivot link 530.
The pivot assembly 500 can be arranged in a wide variety of ways to achieve the structural relationships described above. For example, the pivot bracket 510 can include a mounting portion 514, an interface portion 516 and a neck 518 joining the mounting portion 514 and the interface portion 516. As shown in FIG. 24, the interface portion 516 can include a pivot bore 517 with an extension 515 configured to interfere with the first stop member 536 to resist rotation about the third pivot axis 534.
The pivot link 530 can also include a pivot pin 535 extending from the top surface of the pivot link 530 along the third pivot axis 534. The pivot pin 535, together with the first stop member 536 can be inserted within the pivot bore 517 of the pivot bracket 510 and fastened in place. Indeed, as shown in FIGS. 20 and 21, a washer 546 may be placed over a top surface of the interface portion 516. Next, a fastener 548 may be inserted through the washer 546, through an aperture in the top surface of the interface portion 516 and threaded into an interior threaded bore 535a of the pivot pin 535. Once attached together, as shown in FIG. 24, the first stop member 536 of the pivot link 530 is configured to interact with the extension 515 of the mounting bracket 510 to limit the extent to which the pivot link 530 can pivot with respect to the pivot bracket 510.
The pivot assembly 500 can also include a second stop member 524 configured to limit the extent to which the pivot arm 520 can pivot with respect to the pivot link 530. Although the first and second stop members 536, 524 are illustrated together, further examples of the pivot assembly 500 may only include the first stop member 536 or may only include the second stop member 524. As further shown in FIG. 21, the pivot arm 520 can include a pivot pin 525 extending from the side of the pivot arm 520 along the second pivot axis 532. The pivot pin 525, together with the second stop member 524 can be inserted within the pivot bore 538 defined in the pivot link 530 and fastened in place. Indeed, as shown in FIGS. 20 and 21, a washer 550 may be placed over a side surface of the pivot link 530. Next, a fastener 552 may be inserted through the washer 550, through an aperture in the side surface of the pivot link 530 and threaded into an interior threaded bore 525a of the pivot pin 525. Once attached together, as shown in FIG. 23, the second stop member 524 of the pivot arm 520 is configured to travel within the slot 540a and interact with first and second shoulders 542a, 544a to limit the extent to which the pivot arm 520 can pivot with respect to the pivot link 530 about the second pivot axis 532.
Although not shown, in an alternate configuration, the pivot pin 525 of the pivot arm 520 may be inserted through an aperture in the opposite side surface of the pivot line 530 to provide a pivot assembly 500 that may be mounted to an opposite end of the lead rail 220. Once attached together, with reference to FIG. 22, the second stop member 524 of the pivot arm 520 would be configured to travel within a second arcuate slot 540b and interact with first and second shoulders 542b, 544b of the second arcuate slot 540b to limit the extent to which the pivot arm 520 can pivot with respect to the pivot link 530 about the second pivot axis 532. Thus, the second arcuate slot 540b allows alternate mounting of the pivot arm 520 between opposite sides of the pivot link 530 to allow the pivot assembly 500 to be assembled as a right or left side pivot assembly.
Use of the pivot assembly 500 to assist in pivoting the first support leg 230 from the deployed position to the stowed position will now be described with reference to FIG. 18. In order to stow the first support leg 230, a user may first pivot the first support leg 230 about a first axis 522 along pivot arrow R1 by approximately 90° along pivot arrow R. A stop may be incorporated to limit the extent to which the first support leg 230 pivots along pivot arrow R1.
Next, the user may rotate the first support leg 230 about a second axis 532 along pivot arrow R2. A user will be prevented from rotating the first support leg 230 in a direction opposite to pivot arrow R2 by an interaction between the second stop member 524 and the second shoulder 544a. As the user rotates the first support leg 230 about the second axis 532 in the R2 direction, the second stop member 524 travels within the arcuate slot 540a until the second stop member 524 engages the first shoulder 542a to limit the extent to which the pivot arm 520 may pivot with respect to the pivot link 530. In one example, the second stop member 524 provides at least about a 90° limit to which the pivot arm 520 can pivot with respect to the pivot link 530. In a further example, the second stop member 524 provides about a 90° limit to which the pivot arm 520 can pivot with respect to the pivot link 530.
Finally, the user may rotate the first support leg 230 about a third axis 534 along pivot arrow R3. A user will be prevented from rotating the first support leg 230 in a direction opposite to pivot arrow R3 by an interaction between the first stop member 536 and the extension 515 As the user rotates the first support leg 230 about the third axis 534 in the R3 direction, the first stop member 536 travels within the pivot bore 517 until the first support leg 230 engages the back of the lead rail 220. Thus, the first stop member 536 together with the lead rail 220 provides a limit to which the pivot link 530 can pivot with respect to the pivot bracket 510. In one example, the first stop member 536 together with the lead rail 220 provides at least about a 90° limit to which the pivot link 530 can pivot with respect to the pivot bracket 510. In a further example, the first stop member 536 together with the lead rail 220 provides about a 90° limit to which the pivot link 530 can pivot with respect to the pivot bracket 510. After pivoting about the third pivot axis 534, the first support leg 230 is stowed within an interior area of the lead rail 220.
In accordance with further examples of the present invention, the awning assembly 100 may include a second support leg 330 in addition to the previously mentioned first support leg 230. As shown in FIGS. 19 and 26, each support leg 230, 330 can include a first segment 240, 340 configured to be attached to the lead rail 220, for instance, with the above mentioned pivot assembly 500. The process of mounting the pivot assembly 500 to the first segment is illustrated with respect to the first segment 340 illustrated in FIG. 27 wherein it is apparent that a similar or identical mounting process may apply for the first segment 240. As shown in FIG. 27, an end cap 348 may be mounted the first segment 340, for example, by way of a rivet 349 or other fastening structure. A pivot pin 502 may then be used to pivotally attach the pivot assembly 500 to the end cap 348.
Each support leg 230, 330 can further include a second segment 250, 350 attached to the first segment 240, 340, and a locking device 260, 360 configured to selectively lock the second segment 250, 350 with respect to the first segment 240, 340 in a selected one of a plurality of alternate relative positions to allow the support legs 230, 330 to be selectively locked in one of a plurality of predetermined incremental lengths. Allowing each of the support legs 230, 330 to be incrementally locked can be beneficial to allow each support leg 230, 330 to obtain an identical length which may prove difficult to achieve with infinitely adjustable support legs.
The first segment, second segment and/or locking device may comprise a wide range of structures to achieve incremental length adjustment. Moreover, different or substantially similar structural arrangements between the support legs may be provided to achieve incremental length adjustment. As shown, for example, each first segment 240, 340 can include an elongated slot 242, 342 with a slot width (w), and a plurality of enlarged openings 244, 344 spaced in series along the slot 242, 342 and in communication with the slot 242, 342. As shown, the enlarged openings 244, 344 each include a dimension (d) that is greater than the slot width (w). FIG. 28 illustrates and exploded view of one example of a locking device 360. Only one locking device will be described since it is understood that the locking device 360 of the second support leg can be similar or identical to the locking device 260 of the first support leg. With reference to FIG. 28, the locking device 360 can include a pull member 361 with a handle 368, a stop-element 362 attached to the handle 368 and a device link 366 extending from the stop element 362. The stop element 362 can have a shape corresponding to the shape of the enlarged openings 344 of the first segment 340 and the device link 366 can be configured to extend through the slot 342 of the first segment 340. A biasing member 364 can be configured to urge the stop element 362 into a locking position. To assemble the pull member 361 to the second segment 350, the device link 366 is inserted through an aperture 352 of the second segment 350. The biasing member 364, such as a compression coil spring, may then be inserted over the device link 366 and precompressed. A press washer 365 can then be inserted over the device link 366 and a fastener 367, such as a clip, can be received within a groove in the end of the device link 366 to maintain the biasing member 364 in a precompressed condition. Therefore, it will be appreciated, that the biasing member 364 will be effective to bias the pull member 361 towards the second segment 350.
Referencing FIG. 26, the second segment 350 may be telescopingly received within the first segment 340. A locking element 354 may then be attached to an end 341 of the first segment 340 to prevent removal of the second segment 350 from telescoping engagement with the first segment 340. In order to adjust the length of the second support leg 330, the handle 368 may be pulled outward against the bias of the biasing member 364 such that the stop element 362 is pulled out of engagement with an enlarged opening 344. The user continues to pull the handle 368 outward and telescopingly adjusts the second segment 350 with respect to the first segment 340. As the segments 340, 350 are moved relative to one another, the device link 366 freely travels within the elongated slot 342. Once the user obtains a length within the desired range, the handle is released. The biasing member 364 then pulls the pull member such that the stop element 362 is urged against an outside of the slot 342 or within one of the enlarged openings 344. If the stop element is urged against the outside of the slot 342 the user then makes a slight adjustment of the relative position between the segments until the stop element 362 is aligned with an enlarged opening 344. Once aligned, the biasing member 364 automatically pulls the stop element 362 into the enlarged opening 344 to lock the second support leg 330 at the selected incremental length. A similar procedure may also be carried out with the first support leg 230 such that identical lengths may be achieved.
As shown in FIGS. 26, 28 and 29, the second support leg 330 can also include a third segment 370 a biasing member 380 configured to bias the third segment 370 to an extended position with respect to the second segment 350. As shown in FIG. 29, a mounting bracket 382 may be attached to a first end 381a of the biasing member 380 and a second end 381b of the biasing member 380 may be attached to an end of the third segment 370. The mounting bracket 382, together with the first end 381a of the biasing member 380 may then be inserted within the second segment 350. A fastener 384, such as a rivet, may then be used to attach the mounting bracket 382 to the second segment 350. The biasing member can comprise a wide range of devices. As illustrated, the biasing member 380 comprises a gas spring although other devices may be used in further examples.
FIGS. 30-32 illustrate another example of a second and third segment 450, 470. A biasing member 480 is provided that comprises a compression spring 482 mounted about a rod 484. The biasing member 480 is configured to bias the third segment 470 to an extended position with respect to the second segment 450. As shown in FIGS. 31 and 32, a mounting bracket 486 may be attached to a first end 481a of the biasing member 480 and a second end 481b of the biasing member 480 may be attached trapped within the third segment 470. For example, a cross member 488 may be received within a lateral slot in the end of the third segment 470 and a pair of screws 490a, 490b may trap the cross member 488 within the third segment 470. As shown in FIG. 31, the mounting bracket 486 may be inserted into an interior area of the second segment 450 and fastened to the second segment 450, for example, with a rivet 492 or other fastener.
A method of using the support legs 230, 330 will be described with respect to FIGS. 2A and 2B. As previously described, the first and second support legs both provide for incremental adjustment such that the length of each leg may be set at substantially identical lengths to provide a substantially level lead rail 220 as shown in FIG. 2A. Moreover, the second support leg 330 can include the third segment 370 and biasing member 380. The second support leg 330 allows the awning assembly to be incrementally adjusted as well as provide for a shed function if a predetermined weight (W) is experienced. As shown in FIG. 2B, if a predetermined weight (W) is positioned on a portion of the flexible awning material 102, the biasing member 380 is configured to permit movement of the third segment 370 with respect to the second segment 350 to shed weight from the awning material 102 after which the biasing member 380 again biases the third segment 370 to the extended position with respect to the second segment 350.
Operation of the awning assembly 100 will be described. From a fully retracted position, a user may operate a control to begin deployment of the awning assembly 100. During deployment, the arm assemblies 110a, 110b force the lead rail 220 to begin moving away from the back cover 400 wherein the flexible awning material 102 begins to unroll from the roller tube 410. The motor within the roller tube 410 can act as a braking mechanism during deployment to prevent the arm assemblies 110a, 110b from extending the lead rail 220 too quickly. A limit switch can be activated to indicate the fully deployed position wherein the motor prevents further movement of the lead rail 220 with respect to the back cover 400. Once deployed, each support leg 230, 330 may be deployed from the lead rail 220 and pivoted down. The foot of each support leg can be engaged with a ground surface or the foot can be attached to a side of the support structure 600. The 368 handle of each locking device 260, 360 may be pulled to release the stop element 362 from the respective enlarged opening 344 to adjust the overall length of the support legs. Once the desired length is achieved, the pull handle 368 may be released to allow the stop element 362 to be pulled back into the appropriate enlarged opening 344.
In order to retract the awning assembly 100, the support legs 230, 330 are pivoted back up and stored with respect to the lead rail 220. Next, a user interfaces with a control to cause the motor within the roller tube 410 to begin rolling the awning material 102 back on the roller tube 410. As the roller tube 410 pulls on the awning material 102, the lead rail 220 begins moving back towards the back cover 400 against the bias of the arm assemblies 110a, 110b. A triggering mechanism can be provided to turn off the motor once the fully retracted position is achieved. The triggering mechanism may comprise, for example, a limit switch or a controlled response to a predetermined change in voltage or current supplying electricity to the motor due to an overload condition of the motor.
From the above description of the invention, those skilled in the art will perceive improvements, changes and modifications. Such improvements, changes and modifications within the skill of the art are intended to be covered by the appended claims.
