Comparison Doppler 74566 vs Doppler 74367N1

The presence in the design of the umbrella of reinforced elements and additional parts that provide protection from strong winds. Note that the essence of such protection is not so much the prevention of eversion, but the ability to withstand bad weather without breaking. In other words, most storm umbrellas can easily turn inside out, but they endure this trouble without any consequences and easily return to normal working shape. And the wind directed from the outside, they resist much better than ordinary ones. Therefore, if you often have to be outside during heavy rains with strong winds, it makes sense to pay attention to models with this function.

The material from which the umbrella's ribs are made. It may differ from the frame material (see the corresponding section), which is why this parameter is listed separately.

— Steel. One of the most common materials for ribs. Modern umbrellas may use different grades of steel, varying in price and quality; typically, this aspect directly correlates with the umbrella's price category. However, in any case, this material is quite strong, flexible, reliable, and durable, and is relatively inexpensive. The main disadvantage of steel is its comparatively large weight.

— Aluminum. Compared to steel, aluminum is distinguished by a lower weight on the one hand, and relatively low strength on the other. Consequently, it is relatively rare, mainly found in children's umbrellas and budget "adult" models.

— Fiberglass. Fiberglass ribs combine high flexibility, corrosion resistance, and cold resistance: in strong winds, such ribs spring back and restore the canopy shape without a "bend memory," and do not become brittle in freezing temperatures. This has led to their popularity in storm and golf umbrellas, as well as urban walking canes prioritizing wind resistance. In comparison: with steel, fiberglass is noticeably lighter and does not rust, but falls short in "edge stiffness" and is more likely to break than bend under critical impact; with aluminum, i...t excels in elasticity and resistance to inverting, avoiding permanent folds, although it might be slightly heavier at equal stiffness; relative to carbon fiber, fiberglass is more ductile and "tougher" against impact, cheaper and thicker at the same level of stiffness, while carbon is lighter and stiffer for premium storm models but more expensive and breaks "on snap," without warning deformations.

— Carbon Fiber. Carbon fiber ribs have the maximum stiffness-to-weight ratio: the canopy maintains its shape better in gusty winds, "flutters" less and returns to its original position more quickly with a compact rib diameter. The material is resistant to corrosion but requires high-quality resin and protective lacquer for UV resistance and micro-crack prevention at the joints. This solution is found in premium storm and golf umbrellas, as well as ultra-light travel models, where minimal weight and precise geometry are important. Compared to fiberglass, carbon fiber is noticeably lighter and stiffer at the same thickness, providing better wind resistance and sharper edge shape, but is less ductile and breaks without warning bends when overloaded, also being more expensive; fiberglass is more elastic, tolerates frequent inversions and targeted impacts better, though with a slight loss of "sharp" stiffness.

The diameter of the umbrella dome when unfolded. The larger the diameter of the dome, the more reliably it will protect you from rain and the easier it will be to place one more person under the umbrella. On the other hand, a wide umbrella can be uncomfortable in tight spaces — for example, in the flow of pedestrians on a busy street — and when folded it will take up more space. Therefore, it does not always make sense to choose the largest of the available options.

The minimum diameter for an "adult" umbrella (see "Destination") is considered to be about 80 cm. Most models are in the range of 90 – 110 cm — this provides a good degree of protection with ease of movement. And in the largest modern products, the diameter of the dome can reach 150 cm.

The length of the umbrella when folded. For the decomposed one, this parameter is not specified, because is not critical, but when transporting a closed umbrella, it is the length that is the most important dimension.

The length of cane umbrellas (see "Type") is, by definition, the same when open or closed; most often it is 60 – 90% of the dome diameter (see above). But folding models of the same diameter can vary markedly in length, and here the choice depends on the situation: on the one hand, more compact umbrellas are more convenient to carry, on the other hand, they are less reliable and more complex in design, and also cost more.

— Plastic. As a material for umbrella handles, plastic is very practical: it has a low price, is resistant to moisture, and its strength, although lower than that of metals, is quite sufficient in this case, especially since there are many varieties of this material on the market, including number and are very durable. It is also worth noting the low thermal conductivity of plastic — it does not "cool" the hand in cool weather. Similar handles are used in umbrellas of all price categories.

— Tree. Wood, like plastic, does not conduct heat well and does not cool the hand, while many consider it more pleasant to the touch; Yes, and this material looks quite stylish. At the same time, wooden handles are somewhat more expensive, and their quality noticeably depends on the price category of the umbrella (although in a cheap product, the frame is more likely to break than the handle).

— Skin. In this case, of course, we are talking about a handle made of hard material (usually wood or plastic, see above), covered with genuine leather. Such a coating gives the pen a rich and solid appearance and well emphasizes the image of the owner — after all, leather is quite expensive. Of the practical disadvantages of this option, it is worth noting the exactingness of care — otherwise the material may lose its presentation.

— Metal....Metal handles are usually an integral extension of the central rod. They are very durable, besides they look stylish, but they tend to "cool" the hand and slip out of it — therefore they are rarely used, mainly in designer models.

— EVA foam. Handles in the form of a solid base (usually the same material as the frame), covered with a layer of ethylene vinyl acetate (EVA) foam. This coating is pleasant to the touch, does not slip in the hand and provides a secure hold. At the same time, for a number of reasons, this option is found mainly in premium models.

— Hook. The characteristic curved handle allows you to hang the umbrella on any suitable device - the back of a chair, a clothes hanger, etc. In addition, it is quite secure when held and provides a stylish appearance with a hint of traditional classics. On the other hand, a hook makes the entire product more bulky and inconvenient to transport - therefore, it is found mainly among canes (see “Type”), where the main inconvenience is due to the size of the umbrella itself and depends little on the shape of the handle. Also, some believe that “hooks” are more likely to get lost than models with other types of handles; and this opinion is not without foundation - for example, there is a high probability of forgetting about such an umbrella hung by the handle in an inconspicuous place.

- Direct. An elongated handle of a cylindrical (or close to it) shape; in some models it may be slightly bent - for example, to imitate the knob of a cane. Very comfortable to hold, but not as secure as a hook and less compact than a round one.

- Round. This category includes handles that are close in shape to either a ball or a very short cylinder (the height of which is comparable to the diameter). This option is the most compact and is considered optimal for folding umbrellas(see “Type”), created with ease of portability in mind. On the o...ther hand, in terms of reliability and ease of holding, round handles are inferior to the types described above; This is partly compensated for by the wrist strap provided in many similar models.

- C-shaped. A rather unusual type of handle is in the form of a loop with a small slot resembling the letter C. The slot is provided so that the umbrella can be hung on a rope or other similar device. In any case, this form provides two advantages over more traditional options. Firstly, it provides more grip options - you can grab the bottom of the loop, the side, between them, etc. Secondly, it allows you to free your hands when holding an open umbrella: the C-shaped handle can be put on the wrist, and The central rod should be rested on the shoulder; as a result, the hand will be free. On the other hand, this type of handle is quite bulky and expensive; It is because of this that they have not gained much popularity.

The type of clasp installed on the umbrella strap.

We are talking about a strap that tightly secures the dome in the closed position. Most often, Velcro or a button is used as a fastener, and in some models a button is used. Here is a description of each option:

- Velcro. The most popular type of fastener these days. Velcro is inexpensive, extremely compact (in particular, it does not protrude above the strap, unlike buttons), and is also easy to use - so they can be found in all price categories of umbrellas. The main disadvantage of such devices is that as they wear out, their effectiveness drops noticeably - to the point that at one point the Velcro stops holding it at all. However, the service life of such fasteners is still usually quite long, and worn-out Velcro can be replaced without any problems or costs in a workshop or even on your own.

- Button. The clasp is in the form of a characteristic metal button, like clothing buttons. Such devices are much more reliable and durable than Velcro, but they are more expensive and somewhat less convenient: unfastening the button requires a certain amount of force, and fastening it also requires greater precision. In addition, not all users like the part that noticeably protrudes from the strap when the umbrella is closed. In light of this, buttons are used much less often than Velcro, and mainly in models of the middle and to...p price categories (with rare exceptions).

- Button. An ordinary button that, when fastened, is threaded into a loop. From a practical point of view, such fasteners are noticeably inferior to Velcro and buttons - they are not as reliable, and they are not particularly convenient. Therefore, buttons can be found extremely rarely in our time - in individual cane umbrellas in the “retro” style, where such a fastener is used primarily as a characteristic design element.

Total weight of the umbrella.

All other things being equal, lighter umbrellas are more convenient to carry (both in the open and closed positions). On the other hand, such products are less reliable and/or more expensive than relatively heavy models of similar design and size. We also note that in some cases, significant weight can be an advantage. For example, in a strong wind, a massive umbrella does not “tear from your hands” as much, and when released, it does not fly as far as a lighter one.
