DETAILED DESCRIPTION

Disclosed is a retractable awning comprising: a slotted track; a webbing disposed in the slotted track; a cover attached to the webbing and disposed on the slotted track; a first roller disposed at a first end of the slotted track and connected to a first end of the webbing; a second roller disposed at a second opposite end of the slotted track and connected to a second end of the webbing; and a bracket, the bracket disposed over the first roller and comprising a guide roller which contacts the cover when the retractable awing is in a deployed position between the first roller and a first end of the slotted track.

The slotted track may have a slotted cross-section as shown in FIG. 1A or 1B, and may have any suitable length, wherein the length may be selected based on the desired dimensions of the awning. The slotted track of FIG. 1A may be mounted on a third portion. As shown in FIG. 1A, the slotted track may have an overall width W₁, a slot width W₂, and inner width W₃, an overall height H₁, and an inner height H₂. The inner height H₂ may be constant or may be varied. For example, the inner height may increase from an outer edge of the slotted track to the slot edge. The overall width W₁ may be 6 millimeters (mm) to 110 mm, 10 mm to 100 mm, or 15 mm to 80 mm. The slot width W₂ may be 2 mm to 25 mm, 4 mm to 20 mm, or 6 mm to 15 mm. The inner width W₃ may be 4 mm to 100 mm, 6 mm to 90 mm, or 8 mm to 80 mm. The overall height H₁ may be 10 mm to 100 mm, 15 mm to 90 mm, or 20 mm to 80 mm. The inner height H₂ may be 8 mm to 90 mm, 15 mm to 80 mm, or 20 mm to 70 mm.

As illustrated in FIG. 1B, the slotted track may comprise a first portion 150 and a second portion 160, each of which independently may have a C shape or an L shape as illustrated in FIG. 1B and in FIG. 5. A third portion 170 may be disposed between the first portion and the second portion. The first portion 150 and the second portion 160 may be connected as a single track piece while allowing for the slot opening and the third portion 170 may be disposed therein the single track piece. In order to accommodate the webbing, a webbing gap 155 may be located in between the first portion and the third portion and also between the second portion and the third portion. The first portion and the second portion may each independently have a width W₄ and a height H₃, wherein the width W₄ may be 10 mm to 250 mm, 20 mm to 200 mm, or 30 mm to 150 mm, and wherein the height H₃ may be 10 mm to 250 mm, 20 mm to 200 mm, or 30 mm to 150 mm. The third portion 170 may have any suitable size, and may be selected to have any suitable dimensions.

The slotted track may comprise any suitable material, and may comprise a metal (such as aluminum, steel, or a corrosion resistant steel) a synthetic polymeric material (such as polypropylene, polyethylene, a polyamide such as nylon, polycarbonate, acrylic, polyethylene terephthalate), wood, or a combination thereof. The first portion, the second portion, and the third portion may each independently comprise any suitable material, and may comprise a metal (such as aluminum, steel, or a corrosion resistant steel) a synthetic polymeric material (such as polypropylene, polyethylene, a polyamide such as nylon, polycarbonate, acrylic, polyethylene terephthalate), wood, or a combination thereof. For example, the first and second portions may comprise a metal and the third portion may comprise wood or a synthetic polymeric material.

The webbing is selected to fit within the slotted track. The webbing may have a width of 3 mm to 90 mm, 5 mm to 85 mm, 10 mm to 80 mm, or 20 mm to 70 mm, and may have a thickness of 1 mm to 5 mm, 1.5 mm to 4.5 mm, 2 mm to 4 mm, or 3 mm. The webbing may comprise a polyamide such as nylon, polypropylene, polyester, or a combination thereof.

The cover comprises any suitable material, and may comprise an olefin such as polyester or polypropylene, cotton, rayon, a polyamide such as nylon, acrylic, polyethylene terephthalate, polyurethane, vinyl, or a combination thereof. The cover is connected to the webbing in a direction parallel to the length of the slotted track so that the webbing may ride within the slotted track while the cover rides on the slotted track. The cover may be attached to the webbing with thread, an electro-seal, a weld such as a heat weld, an adhesive weld, a sonic weld, or a combination thereof. A sewn connection is specifically mentioned. The cover, when in a deployed configuration, is on the slotted track.

It has been surprisingly discovered that certain combinations of webbing and slotted track dimensions provide improved performance. Slotted tracks having a larger slot width W₂ are best used with a webbing having a greater latitudinal stiffness, and webbing having less latitudinal stiffness may be used if a slotted track having a narrower slot width W₂ is provided. A suitable combination of webbing and slotted track may be defined based on a pull test, in which a 0.1 meter (m) section of webbing is connected to a cover, the webbing disposed in the slot and the cover on the slotted track, and the cover pulled in a direction perpendicular to the slot until the webbing is pulled through the slot. It has been discovered that use of a webbing and slot combination in which the webbing is retained within the slot when the cover is pulled with a force, F, of 30 newtons (N) force perpendicular to the slot provides improved results. In an embodiment, the webbing and slot combination provides a pull resistance of 30 N to 200 N, 40 N to 150 N, or 50 N to 125 N, when determined by pulling a cover attached to a 0.1 m section of webbing in a direction perpendicular to the slot until the webbing is pulled through the slot. An illustration of a pull test is illustrated in FIG. 2A, which shows a section of webbing 210 sewn to a cover 220 and the webbing inserted into a slotted track 230, and FIG. 2B, which is a schematic diagram of an embodiment of a section of webbing 210 sewn into a cover 220 by thread 215 and inserted into a slotted track 230. As shown in FIG. 2B, the webbing is located within the slot of the slotted track and is attached to the cover to 220. In the pull test, load, F, is added to the cover until the webbing pulls out of the track.

The retractable awning comprises a first roller 310 disposed in a first end of the slotted track, and a second roller 320 disposed at a second opposite end of the slotted track, as shown in FIG. 3. An end of the first roller 310 is shown in further detail in FIG. 4, and an end of the second roller 320 is shown in further detail in FIG. 5. When in a retracted configuration, the first roller 310 holds the rolled cover. When the awning is deployed, the second roller takes up the webbing, which is connected to the cover, to pull the cover over the slotted track. A motor may be connected to one or both of the first roller 310 and the second roller 320. In an embodiment, a first motor connected to the first roller 310 and a second motor is connected to the second roller 320. The first motor and the second motor may be controlled by a controller so that they operate in synchrony. Also, the controller may operate the first motor and the second motor so that a suitable tension is maintained on the webbing.

In order to maintain a tension of the webbing, one or both of the first roller 310 and the second roller 320 may each independently be raised relative to a height of the slotted track. The webbing in the slotted track and the webbing between a guide and a roller may be at a rolling angle of 0 to 60°, or 20 to 50°. In order to achieve the rolling angle, one or both of the first roller 310 and the second roller 320 may mounted on an adjustable mount 810, for example, as illustrated in FIG. 4 and FIG. 5.

Depending on the desired width of the awning, a plurality of slotted tracks may be provided. For example, shown in FIG. 3 is a first outer slotted track 230 and an opposite second outer slotted track 236. Also provided are inner slotted tracks 232 and 234 disposed between the first outer slotted track 230 and the second outer slotted track 236. The number of slotted tracks may be 2 to 50, 3 to 45, 4 to 40, or 5 to 30.

The slotted track may have an angled leading edge 250, for example, as illustrated in FIG. 10. The angled leading edge 250 may help guide the cover leading edge 222 to the upper surface of the slotted track 230. The angle's leading edge may be at an edge angle of 5 to 85°, or 20 to 50° relative to the upper surface of the slotted track.

Also disclosed is a bracket 610 to guide the webbing where the webbing enters the track, as shown in FIG. 3 and FIG. 4. As shown in FIG. 3, the bracket may comprise a first outer bracket 610, a second outer bracket 616, and inner brackets 612 and 614. In an embodiment, a bracket is disposed on each slotted track. An alternative bracket, for wall mounting, is shown in FIG. 6.

Each bracket may comprise a guide roller 740. The guide roller is disposed on the cover and on the webbing, so as to guide the webbing into and out of the slotted track. It has been discovered that by angling the guide roller or by utilizing a slanted guide roller on the outer brackets towards an outer edge of the awning, departure of the webbing from the slotted track is avoided and wrinkles in the cover are reduced. An angled guide roller 742 is shown in FIG. 4 and a slanted guide roller 744 is shown in FIG. 9. In an embodiment, the angled guide roller is angled away from the center of the retractable awning. For example, the angled guide roller may be angled at an angle of 2° to 45°, 4° to 35°, or 6° to 25° relative to an upper surface of the slotted track. The upper surface of the slotted track 230 may conform to the surface of the angled guide roller as is illustrated in FIG. 9. The slanted guide roller 744 may have a large roller end with a maximum diameter and a small roller end with a minimum diameter, wherein the small roller end may be facing away from a center of the cover and towards an outer edge of the cover.

Also provided, as shown in FIG. 5, is a webbing guide 510 between the slotted track and the second roller. The guide guides the webbing between the slotted track and the second roller. The webbing guide may be aligned with, for example, parallel to a surface of the webbing. Alternatively, a bracket 610, as shown in FIG. 6, may be used instead of the webbing guide 510, or a combination of the guide and the bracket may be used. In an embodiment, the bracket over the second roller 320 may comprise an outer bracket on either side of a middle bracket, wherein brackets over the second roller are as disclosed for the first outer bracket 610, the second outer bracket 616, and the middle brackets 612 and 614.

In addition, disclosed is a shield 910, for example, as shown in FIG. 7. The shield may be disposed in between two brackets as illustrated in FIG. 7 or may be disposed on a bracket or brackets to protect the one or both of the roller and the bracket. The shield may provide improved ornamental appearance. A shield edge may be at an angle relative to the first roller to direct any debris to an outer edge and potentially off of the cover. In addition, a brush 920, for example, as shown in FIG. 8 may be provided to sweep away any debris which may be on the cover to keep debris from being entrained within the rolled up cover. The brush may be disposed in between two brackets as illustrated in FIG. 8 or may be disposed on a bracket or brackets to protect the one or both of the roller and the bracket. A brush edge may be at an angle relative to the first roller to direct any debris to an outer edge and potentially off of the cover.

Also disclosed is a retractable awning system, the system comprising: a first retractable awning; a second retractable awning disposed adjacent to the first retractable awning; and a membrane connecting a cover of the first retractable awning to a cover of the second retractable awning, wherein each of the first retractable awning and the second retractable awning each comprise a slotted track, a webbing disposed in the slotted track, a cover attached to the webbing and disposed on the slotted track, a first roller disposed at a first end of the slotted track and connected to a first end of the webbing, a second roller disposed at a second opposite end of the slotted track and connected to a second end of the webbing, and a bracket, the bracket disposed over the first roller and comprising a guide roller which contacts the cover when the retractable awing is in a deployed position between the first roller and the first end of the slotted track.

The membrane may comprise any suitable material and may comprise, for example, an olefin (such as polyester or polypropylene), cotton, rayon, a polyamide (such as nylon), an acrylic, polyethylene terephthalate, a polyurethane, a vinyl, or a combination thereof. The membrane may be connected to the adjacent covers to provide a seamless and leakproof transition between adjacent covers.

Also disclosed is a method of deploying an awning, the method comprising: providing a retractable awning comprising a slotted track, a webbing disposed in the slotted track, a cover attached to the webbing and disposed on the slotted track, a first roller disposed at a first end of the slotted track and connected to a first end of the webbing, a second roller disposed at a second opposite end of the slotted track and connected to a second end of the webbing, and a bracket, the bracket disposed over the first roller and comprising a guide roller which contacts the cover when the retractable awing is in a deployed position between the first roller and a first end of the slotted track; and turning the second roller to unwind the cover and deploy the awning. The first and second rollers may each individually be turned by any suitable means, such as a handcrank or a motor, for example. Use of electric motors disposed within each roller is specifically mentioned. The motors may be controlled by a controller, which directs the first motor and the second motor to turn the first roller and the second roller to deploy the awning. In an embodiment, the controller maintains a suitable tension on the webbing while the awning is being deployed and retracted. The controller may be actuated by a switch, enabling a user to automatically deploy or retract the awning as desired.
