DETAILED DESCRIPTION OF THE INVENTION

Reference is now made to the Drawings wherein like reference characters denote like or similar parts throughout the various Figures. Referring now to FIG. 1, a perspective view of an awning assembly in accordance with an embodiment of the present invention is illustrated. The awning assembly 10 illustrated in FIG. 1 includes a frame assembly comprised of a first support leg 12a and a second support leg 12b attached to and supporting a horizontal truss brace 14. Although not required, a first curved truss brace 15a and a second curved truss brace 15b may be further attached between the first support leg 12a and the horizontal truss brace 14, and the second support leg 12b and the second curved truss brace 15b, respectively, to provide additional support. A first base plate 16a may be attached to the first support leg 12a and a second base plate 16b may be attached to the second support leg 12b in order to provide increased stability to the awning assembly 10. In one embodiment, the first base plate 16a can further be provided with mounting holes in order to facilitate the mounting of the awning assembly 10 to a mounting surface. The awning assembly 10 further includes a roller tube assembly 18 having a roller tube 20 attached to a top surface of the horizontal truss brace 14. In an alternate embodiment of the present invention, the roller tube 20 can be attached to the first support leg 12a and the second support leg 12b, and the horizontal truss brace 14 can be eliminated.

A first glide rail 22a and a second glide rail 22b are attached to an inner side of and extend along a portion of the vertical length of the first support leg 12a and the second support leg 12b, respectively. The first glide rail 22a is adapted to allow a first glide block 24a to slide along the first glide rail 22a, and the second glide rail 22b is adapted to allow a second glide block 24b to slide along the second glide rail 22b. These glide rails can be integral to the support legs or made as a separate piece. Alternately, the guide rails may be in the form of a grooved arrangement within the support legs.

In this embodiment, the awning assembly 10 further includes a first glide block ribbon 25a having a first end attached to the first glide block 24a and a second end attached to the roller tube 20. In a substantially similar manner, the awning assembly 10 further includes a second glide block ribbon 25b having a first end attached to the second glide block 24b and a second end attached to the roller tube 20. The first glide block 24a and the second glide block 24b in combination/cooperation with each other and the first glide block ribbon 25a and the second glide block ribbon 25b serve as a raising lowering mechanism. It should be understood that other raising/lowering mechanisms may be used to raise and lower the first glide block 24a and the second glide block 24b instead of the first glide block ribbon 25a and the second glide block ribbon 25b used in this embodiment. Other raising/lowering mechanisms that may be used to raise and lower the first glide block 24a and the second glide block 24b could include, for example, the use of tapes, cords, chains, screw drives, either alone or in combination, or the like.

The awning assembly 10 further includes a first end of a first front arm 26a and a first end of a first rear arm 28a attached to opposing sides of the first glide block 24a via hinged attachment points. A first end of a second front arm 26b and a first end of a second rear arm 28b are attached to opposing sides of the second glide block 24b via hinged attachment points. A second end of the first front arm 26a and a second end of the second front arm 26b are attached to opposite ends of a front bar 30a, ideally in a semi or completely rigid manner. In a substantially similar manner, a second end of the first rear arm 28a and a second end of the second rear arm 28b are attached to opposite ends of a rear bar 30b, ideally in a rigid manner. Although they may be hinged at one or more of their endpoints, the first front arm 26a, the second front arm 26b, the first rear arm 28a, and the second rear arm 28b are preferably constructed in such a manner that they are rigid (i.e. not hinged) along their entire length. This eliminates a potential point of failure of conventional awning arms that may have one or more articulations positioned in or along their length.

The front bar 30a and rear bar 30b may additionally be provide with slots for the attachment of a front valance 33a and rear valance 33b, respectively. The awning assembly 10 further includes a front canopy material 32a, comprised of a flexible material such as fabric or plastic, having a first end attached to the front bar 30a and a second end attached to the roller tube 20. In a substantially similar manner, the awning assembly 10 includes a rear canopy material 32b having a first end attached to the rear bar 30b and a second end attached to the roller tube 20. The front canopy material 32a and rear canopy material 32b are adapted to provide protection against sunlight, rain, etc. when in a deployed configuration as illustrated in FIG. 1.

Referring now to FIG. 2, a plan view of the frame assembly of the awning assembly 10 of FIG. 1 is illustrated.

Referring now to FIG. 3A, an embodiment of the roller tube 20 of FIG. 1 is illustrated. The roller tube 20 includes a mechanism for attaching of the front canopy material 32a to the roller tube 20, ideally this can be a first slot 21 extending along the length of the roller tube 20 for attachment of the front canopy material 32a and the rear canopy material 32b. The roller tube 20 is adapted to allow the front canopy material 32a and the rear canopy material 32b to be wound and unwound around the roller tube 20 at a single point of attachment.

Referring now to FIG. 3B, another embodiment of the roller tube 20 of FIG. 1 is illustrated. The roller tube 20 includes a mechanism for attaching of the front canopy material 32a to the roller tube 20, ideally this can be a first slot 21 extending along the length of the roller tube 20. The roller tube 20 further includes a includes a mechanism for attaching of the rear canopy material 32b to the roller tube 20, ideally this can be a second slot 23 extending along the length of the roller tube 20. The roller tube 20 is adapted to allow the front canopy material 32a and the rear canopy material to be wound and unwound around the roller tube 20 at attachment points on opposing sides of the roller tube 20. Although slot arrangement(s) are shown in FIGS. 3A and 3B, other attachment methods could be employed.

Referring now to FIG. 3C, an alternate embodiment of the roller tube assembly 18 of FIG. 1. The roller tube assembly 18 of FIG. 3C includes two counter rotating rollers consisting of a first counter-rotating roller tube 35a and a second counter-rotating roller tube 35b. In this embodiment the front canopy material 32a is attached to the first counter-rotating roller tube 35a, and the rear canopy material 32b is attached to the second counter-rotating roller tube 35b. Accordingly, during extension and retract of the front canopy material 32a and the rear canopy material 32b, the first counter-rotating roller tube 35a and the second counter-rotating roller tube 35b rotate in directions counter to each other. Additionally, in yet another embodiment, the two rollers need not be counter-rotating.

Referring now to FIG. 4, an embodiment of the front bar 30a of FIG. 1 is illustrated. The front bar 30a includes a front arm slot 40a for attachment of the first front arm 26a and the second front arm 26b. The front bar 30a further includes at least one of a first slot 42a, and second slot 44a, and a third slot 46a for selective attachment of the front canopy material 32a and the front valence 33a. For example, in one embodiment, the front canopy material 32a may be attached to the front bar 30a at the third slot 46a, and the front valence 33a may be attached to either one of the first slot 42a or the second slot 44a in accordance with whether it is desired to have a portion of the front bar 30a visible or covered by the front valence 33a. It should be understood that the rear bar 30b of the present invention can be constructed in a manner that is substantially similar to that of the front bar 30a.

It should be understood that other configurations of the front bar 30a and rear bar 30b could used. Although a slot arrangement for the attachment of the front canopy material 32a and/or front valence 33a is shown in FIG. 4, other attachment methods could be employed. For example, an alternate embodiment of the front bar 30a can be used such that the front canopy material 32a and the front valence 33a are attached to the front bar 30a using fasteners and/or adhesive material.

Referring now to FIGS. 5A-5C, a front view, a side view, and a top view, respectively of an embodiment of the first glide block 24a of FIG. 1 is illustrated. The first glide block 24a may be constructed of a hollow steel tube 50a having a substantially rectangular cross section. The first glide block 24a further includes, for example, a steel pipe 52a attached to an inner surface of and oriented along an axis extending from a top to a bottom of the hollow steel tube 50a. The first glide block 24a further includes, for example, a fiberglass pipe 54a in contact with an inner surface of the steel pipe 52a in order to allow the first glide block 24a to slide along the first glide rail 22a. In one embodiment of the first glide block 24a one or more bolts can be used in order to secure the attachment of the steel pipe 52a to the inner surface of the follow steel tube 50a. The second glide block 24b may be constructed in a substantially similar manner to that of the first glide block 24a.

Referring now to FIG. 6A-6C, the awning assembly 10 of FIG. 1 is illustrated in various stages of deployment. The awning assembly 10 operates such that as the roller tube 20 is rotated so as to deploy the canopy, each of the first glide block ribbon 25a and second glide block ribbon 25b, used as an exemplary raising/lowering mechanism, are wound around the roller tube 20, resulting in the first slide block 24a and second glide block 24b being pulled in an upward direction along the first glide rail 22a and the second glide rail 22b, respectively. Simultaneous with the winding of the first glide block ribbon 25a and second glide block ribbon 25b around the roller tube 20, the front canopy material 32a and rear canopy material 32b are unwound from the roller tube 20. A hinged movement of the first front bar 26a and second front arm 26b as the first glide block 24a and second glide block 24b move upward results in the outward movement of the front bar 30a thereby deploying the front canopy material 32a into its fully extended position. In one embodiment of the present invention, the hinged attachment of the first front arm 26a and the second front arm 26b to the first glide block 24a and the second glide block 24b may optionally be spring loaded such that outward pressure is placed upon the first front arm 26a and the second front arm 26b to facilitate the extension of the front canopy material 32a.

In addition, as each of the first glide block 24a and second glide block 24b are pulled upward, the hinged movement of the first rear arm 28a and second rear arm 28b results in the outward movement of the rear bar 30b thereby deploying the rear canopy material 32b into its fully extended position. In one embodiment of the present invention, the hinged attachment of the first rear arm 28a and the second rear arm 28b to the first glide block 24a and the second glide block 24b may be optionally spring loaded such that outward pressure is placed upon the first rear arm 28a and the second rear arm 28b to facilitate the extension of the rear canopy material 32b. The extension of the front canopy material 32a and the rear canopy material 32b results in the formation of a protective canopy.

When it is desired to return the awning assembly to its fully retracted position, the roller tube 20 is rotated in a counter direction to that of extension. As the roller tube 20 is rotated in the counter direction, the front canopy material 32a and the rear canopy material 32b are wound around the roller tube 20. In addition, the first glide block ribbon 25a and the second glide block ribbon 25b are unwound from the roller tube 20 as the roller tube 20 is rotated in the counter direction, resulting in the downward movement of the first glide block 24a and the second glide block 24b along the first glide rail 22a and the second glide rail 22b, respectively.

A variety of suitable mechanisms may be used to rotate the roller tube 20 in order to facilitate the retraction and extension of the awning assembly 10. For example, a hand crank located along an outer surface of one of the first support leg 12a and the second support leg 12b having a worm gear attachment to the roller tube assembly 18 may be used such that a user may rotate the hand crank in alternate directions in order to extend or retract the awning assembly. In another example, a electric motor can be used to rotate the roller tube 20 in opposing directions in order to alternately extend and retract the awning assembly 10. These mechanisms can be linked to the raising/lowering mechanisms or can be independent of them.

Referring now to FIG. 6A, a side view of the awning assembly 10 of FIG. 1 is illustrated in a fully retracted position. In the fully retracted position of the awning assembly 10, the first glide block 24a is positioned at the lowest point of its movement along the first glide rail 22a and the first glide block ribbon 25a is substantially unwound from the roller tube 20. The first front arm 26a and first rear arm 28a are folded into an upright position, and the front canopy material 32a and rear canopy material 32b are substantially wound on the roller tube 20.
