DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to FIGS. 1-6, the present invention features a shade system 100 for providing shade. The system 100 comprises a main shaft 110 having a first end 111 and a second end 112. The second end 112 is adapted to engage a hitch receiver 201 on a truck or other vehicle. The second end 112 can be secured to the hitch receiver 201 via a second locking mechanism 118a (e.g., a hitch lock pin or other appropriate mechanism).
The main shaft 110 is generally hollow. A telescopic arm 120 (the inner end 121) is telescopically received in the first end 111 of the main shaft 110. The telescopic arm 120 can be secured in a particular desired position via a first locking mechanism 118b (e.g., a lock pin or other appropriate mechanism).
A vertical shaft 130 extends upwardly from the telescopic arm 120 (e.g., at or near the outer end 122). In some embodiments, the vertical shaft 130 is at an angle, e.g., about 90 degrees, with respect to the telescopic arm 120.
An umbrella holder 140 is disposed on the top end 131 of the vertical shaft 130. The umbrella holder 140 is adapted to receive an umbrella shaft 150. Umbrella shafts of umbrellas 101 are well known to one of ordinary skill in the art. The umbrella shaft 150 can slide upwardly and downwardly through the umbrella holder 140. When a desired height of the umbrella shaft 150 is achieved, the umbrella holder 140 can secure the umbrella shaft 150 in place via an umbrella locking mechanism 160. Such locking mechanisms are well known to one of ordinary skill in the art.
As shown in FIG. 5, in some embodiments, the umbrella 101 may comprise a tilt pivot 104, allowing it to pivot to an appropriate position. Such tilt pivots 104 are well known to one of ordinary skill in the art. As shown in FIG. 6, in some embodiments, the umbrella 101 comprises one or more lights 108 (e.g., disposed on the umbrella shaft 150). In some embodiments, the lights 108 are light emitting diodes (LEDs). In some embodiments, the lights 108 are adjustable. In some embodiments, the umbrella 101 comprises a crank 106 for raising or lowering the umbrella canopy. Such cranks are well known to one of ordinary skill in the art. In some embodiments, the system 100 further comprises cup holders. In some embodiments, the lights 108 can be operatively connected to the vehicle's electrical system.
The main shaft 110 is divided into a first half 210 and a second half 220, the first half 210 comprising the first end 111 and the second half 220 comprising the second end 112. The first half 210 and the second half 220 are connected via a pivot component 230. The pivot component 230 allows the first half 210 to pivot to the first side and to the second side with respect to the second half 220 (e.g., see FIG. 2).
A barrier bar 250 extends outwardly to the first side and to the second side of the main shaft 110 at the pivot component 230. For example, the barrier bar 250 extends outwardly from the main shaft 110 at the pivot component 220 such that the barrier bar 250 is generally perpendicularly to the second half 220 of the main shaft 110. As viewed from the top (with the main shaft 110 not pivoted), the system 100 appears to have a plus-sign shape. The barrier bar 250 is adapted to prevent the first half 210 of the main shaft 110 from pivoting too far to the first side or the second side.
Extending downwardly from the main shaft 110 (at the pivot component 230 region) is a flange 260. Disposed on the flange 260 is a hitch ball 270. Hitch balls are well known to one of ordinary skill in the art. The flange 260 and hitch ball 270 provide the user a means of towing a trailer or other item in a standard manner.
In some embodiments, a first gusset 280a is disposed between the main shaft 110 or pivot component 230 and the flange 260. In some embodiments, a second gusset 280b is disposed between the vertical shaft 130 and the telescopic arm 120.
The system 100 of the present invention may be constructed in a variety of sizes, shapes, styles, and designs.
As used herein, the term “about” refers to plus or minus 10% of the referenced number. For example, an embodiment wherein the main shaft 110 is about 5 feet in length includes a main shaft 110 that is between 4.5 and 5.5 feet in length.
