A Guide to the Parts of a Patio Umbrella

February 5, 2011 by in garden design with Comments Off

I’m consistently surprised with just how few people out there actually know what all the different parts of a patio umbrella are, and just what they’re for. This makes it really difficult to communicate with them about different aspects of various styles or reviews of new upcoming products. If you fall into this category, it may be to your benefit to learn more soon. After all, you wouldn’t want to be with a salesperson who’s talking over your head about an expensive product that you’re considering.

FinialThe word finial describes the decorative top of the umbrella. This is there purely for aesthetics, and doesn’t determine any functionality whatsoever.

CanopyThis refers to the upper part of the patio umbrella and encompasses the umbrella fabric, any wind vents, and rib pockets, each of which has a specific function.

Wind VentsWind vents are critical components of the patio umbrella and ensure that it works correctly. They’re the little openings at the top of the canopy, and they serve two functions. basically, they let air flow through the umbrella instead of getting caught underneath. This ensures that the whole patio umbrella doesn’t simply blow away. In addition, this makes sure that heat doesn’t get trapped in the umbrella. Remember, hot air rises, so having vents at the top means it can keep rising away from you, letting you feel cool and shaded.

FabricThe fabric used for the canopy will play a large role in determining just how effective it is at keeping out the sun’s rays. In addition, different fabrics protect colors more strongly than others. These days, most fabrics for patio umbrellas are made from synthetic fibers to provide good protection from the elements and durability.

RibsThere are two kinds of ribs in your typical patio umbrella – center ribs and outside ribs. The center ribs are what extend from the umbrella pole, specifically from the hub. The outside ribs run along the fabric itself and ensure that the umbrella keeps its shape when extended. The ribs are most often made from the same material as the pole, but sometimes are replaced by fiberglass for high wind resistance.

Hub and RunnerThe hub is where the ribs attach to the pole. Its function is to slide up and down the central pole when the umbrella is extended or contracted. Because the center ribs are attached to this piece, moving the hub will open or close the umbrella. The runner is the device which pushes the hub and forces it to move.

TiltTilt functionality isn’t included in every patio umbrella, but if yours has one its likely right underneath the hub and runner. This will change the tilt of the umbrella so that you can better direct it to ward off the sun.

CrankAt the center of the central pole is a device for opening and closing the patio umbrella. This is typically a turnable crank, especially on aluminum models. On wooden models you may find a pulley and rope setup instead, but it serves the same function.

Central PoleThe central pole is what holds the entire patio umbrella together. This can be made of either wood or aluminum. Wood has a more classic look, but is less durable and strong than its metal counterpart. Choosing the right material for you depends on your specific setup and patio design. Aluminum can always be finished in different colors to match your chosen style.

BaseThe base (or stand) is at the bottom of the umbrella and is the most critical functional component of the entire thing. Choosing the right base is critical because of weight concerns. If the base is too light, the patio umbrella could fall during a strong gust of wind, or even under its own weight. Always err on the heavier side when choosing a base.
