## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This is a continuation-in-part (CIP) of U.S. application Ser. No. 13/730,820, filed Dec. 28, 2012.


FIELD OF INVENTION
The invention relates generally to an apparatus that includes a canopy, a/k/a an umbrella or parasol. More specifically, but without limitation, embodiments of the invention include a method for manufacturing at least a portion of the apparatus.
BACKGROUND
Canopies can be utilized to shield a user from rain, sun, or other environmental conditions. Known canopies have many disadvantages, however. For instance, fixed canopies often suffer from limited ranges of articulation. They may, for example, only tilt along a single plane. Although patio table stands are common, fixed canopies typically have limited mounting options for other applications. Improved canopy systems and methods for manufacturing them are therefore needed.
SUMMARY OF THE INVENTION
Embodiments of the invention solve one or more of the shortcomings described above by affixing a canopy ball onto a shaft of the canopy, and coupling a double-socket arm between the canopy ball and a mounting ball. The double-socket arm provides a wide range of articulation in multiple planes. This specification also discloses a method for manufacturing at least a portion of the disclosed apparatus.

As illustrated in FIG. 20, a mosquito net 2005 can be connected to the cover 110, for instance by stitching, snaps, zipper or other suitable fastener. Such mosquito netting could be included with any of the canopy systems disclosed herein.
FIG. 21 is a flow diagram of a manufacturing process for at least a portion of a canopy 105, according to an embodiment of the invention. The process may be further understood with reference to FIGS. 22 and 23.
After starting in step 2105, the process square-cuts an end of a shaft 115 in step 2110 to produce a mounting end 2220 of the shaft 115. The shaft 115 has a cavity 305 in communication with the mounting end 2220. Step 2110 may be required, for instance, if the shaft 115 is received with a rough or un-square cut on an end of the shaft 115. In embodiments of the invention, a chop saw or similar saw may be used in step 2110. For instance, step 2110 could be accomplished using an abrasive saw with a 3 inch diameter aluminum oxide abrasive disc, together with a suitable fixture to hold the shaft 115 during cutting.
In step 2115, the process secures a canopy ball to a rod. In the embodiment illustrated in FIG. 22, the canopy ball 120 includes a threaded aperture in a neck 315. In the illustrated embodiment, the rod 310 may be, for example, a stainless steel threaded insert. In this instance, step 2115 includes threading the rod 310 into the canopy ball 120, preferably with the application of Red LoctiteTM or other thread locker.
Next, in step 2120, the process secures an elastic band 2205 to the rod 310. The elastic band 2205 is preferably manufactured from relatively soft rubber. For instance, for a rod 310 with a 3⁄8 inch thread, a suitable elastic band 2205 is an orthodontic elastic band of medium thickness and a 5/16 inch diameter when in a relaxed state. The elastic band 2205 is preferably disposed on the rod 310 proximate to the canopy ball 120 as illustrated in FIG. 22. Distance A is preferably less than 0.5 inch and more preferably approx. 1⁄8 inch. The purpose of the elastic band 2205 is to aid in the alignment of the rod 310 with respect to the shaft 115, which will be discussed further below.
The process then disposes the shaft 115 vertically in step 2125, so that the mounting end 2220 of the shaft 115 is on top. A gluing rack (not shown) may be used to hold the shaft 115 in the desired position.
In step 2130, the process inserts a dam 2210 into the cavity 305 from the mounting end 2220 of the shaft 115. The purpose of the dam 2210 is to restrict the flow of an adhesive (discussed below in step 2135). A 1 inch long cotton roll is a suitable dam 2210 for a wide range of adhesive selections. Step 2130 may include using a ram rod (not shown) to push the dam 2210 down the cavity 305. Preferably, the ram rod includes a stop to position the dam 2210 at a predetermined distance (B+C in FIG. 22) from the mounting end 2220 of the shaft 115. If the ram rod is a threaded rod, locking nuts configured to interfere with the shaft 115 can form a suitable stop.
After the dam 2210 is in place, the process applies a first portion 2215 of adhesive into the cavity 305 and adjacent to the dam 2210 from the mounting end 2220 of the shaft 115 in step 2135. Preferably, the adhesive is a 2-part epoxy. In the case of a 2-part epoxy, a mixing straw (not shown) may be used to dispose the first portion 2215. The mixing straw could be included, for instance, as part of a syringe. Alternatively, the mixing straw could be coupled to a pneumatic pump. The dam 2210 restricts the flow of the first portion 2215 of the adhesive.
Next, in step 2140, the process applies a second portion (not shown) of the adhesive to exposed portions of the rod 310. Preferably, step 2140 includes dipping the rod 310 into a container of adhesive. Alternatively, step 2140 could include, for example, brushing or spraying the second portion of adhesive onto the rod 310. A suitable adhesive for steps 2135 and 2140 is an epoxy that includes Cougeon Brother's Inc. M1007 resin and M2032 hardener with a mix ratio of approx. 1:1 by volume.
As soon as practical after application step 2140, the process inserts the rod 310 into the cavity 305 from the mounting end 2220 of the shaft 115. FIG. 23 is a sectional view through the elastic band 2205 illustrating that, in the final assembly of the canopy ball 120 to the shaft 115, the elastic band 2205 aids in the alignment of the rod 310 with respect to the shaft 115.
The process inverts the assembled shaft 115 (and entire canopy 105) in step 2150. A curing rack (not shown) is preferably used in step 2150 to hold the shaft 115 in a vertical position and retain the rod 310 in the cavity 305. Advantageously, in this inverted position, the elastic band 2205 restricts the gravitational flow of adhesive out of the mounting end 2220 of the shaft 115. The adhesive is cured in step 2155 before the process terminates in step 2160.
Variations to the process flow illustrated in FIG. 21 are possible. For example, step 2110 may not be required if the shaft 115 is received with a suitably square cut on the mounting end 2220 of the shaft 115. Also, the sequence of certain steps illustrated in FIG. 21 and described above can be varied without consequence. For instance, in alternative embodiments, steps 2115 and 2120 could be performed at any point in the flow prior to step 2140. And the order of steps 2125 and 2130 could be reversed.
In conclusion, embodiments of the invention provide, among other things, a canopy with an articulating arm, alternative mounting brackets, and a method for manufacturing a portion of the canopy. Those skilled in the art can readily recognize that numerous variations and substitutions may be made in the invention, its use and its configuration to achieve substantially the same results as achieved by the embodiments described herein. Accordingly, there is no intention to limit the invention to the disclosed exemplary forms. In addition, although references are made to embodiments of the invention, all embodiments disclosed herein need not be separate embodiments. In other words, many of the features disclosed herein can be utilized in combinations not expressly illustrated or described.
