Description

Folding umbrella with adjustable umbrella surface

technical field

The invention relates to a folding umbrella with an adjustable umbrella surface, which belongs to the technical field of umbrella design.

Background technique

The use of folding umbrellas is very common throughout the country. It is small and exquisite, easy to place and easy to carry, and is very popular among people. However, compared with straight umbrellas, the ribs are not strong and the wind resistance is poor. Folding umbrellas with small umbrellas have poor rain-shielding ability and cannot cope with the situation where there are many people and few umbrellas; while folding umbrellas with large umbrellas are subject to strong winds, the skeleton is easy to fold back, resulting in a short service life. Occasionally, between the large umbrella surfaces, the umbrella surface and other people are also prone to collisions, causing unnecessary losses.

Aiming at the design of the folding umbrella structure, through the search and analysis of the China National Knowledge Network, China Intellectual Property Network and other literature databases, it is roughly summarized as follows: Fully automatic opening and closing folding umbrella: hold the elastic shell tightly with one hand to open the umbrella, and press the closing button with one hand to close the umbrella. The automatic device is composed of a spring, a rack, a gear, and an umbrella handle sleeve. The gear and rack control the up and down movement of the umbrella handle sleeve to realize the unfolding and closing of the umbrella surface. This kind of umbrella can be opened and closed with one hand, with good hand feeling and more convenient use. A new type of folding umbrella based on the modification of the umbrella surface: the general circular umbrella surface is changed to an octagonal umbrella surface, and the umbrella handle is composed of two-stage hollow octagonal metal rods, which correspond to the umbrella surface and avoid the opposition between the skeleton and the umbrella surface turn. This type of umbrella improves the rain-shielding effect and enhances the wind-resistant performance. Drying-type folding umbrella: the umbrella handle includes a bearing sleeve handle, a screw screw mechanism, a double-ended spiral sleeve and a handle connected together from top to bottom. By normal stretching by hand, the linear motion of the umbrella handle is transformed into the rapid rotation of the umbrella surface, so as to achieve the purpose of quickly drying the water stains on the umbrella surface, but the operation is complicated during the whole use process and the umbrella structure is complicated and easy to be damaged. Reverse inner folding umbrella: the umbrella rib is folded as a whole: the rain cloth and the inner umbrella cloth are set up, and it is opened normally when it rains, and the rain cloth is used to resist the wind and rain. , the rain cloth reaches the inside to prevent the rainwater from hitting other people, but the angle at which the ribs can be turned is too large, and it is easy to fold back when the wind is strong. Elastic reflex rib: the outermost rib is set as an elastic rib that folds inward. When the umbrella touches something else, the outermost rib can be elastically folded inward, preventing the umbrella from damaging something or others . However, when the front of the umbrella faces the wind, it is easy to fold the elastic outer frame inwards, reducing the rain-shielding area. Variable size folding umbrella: one end of the rib of the umbrella handle is set on the handle and can move axially along the handle, the other end is connected to the rib of the umbrella cloth, the second-level umbrella is arranged on the periphery of the first-level umbrella cloth, and the second-level The ribs of the umbrella cloth can be folded along the direction of the ribs of the first-level umbrella cloth, and the edges of the second-level umbrella cloth are connected to the free ends of the ribs of the second-level umbrella cloth. When the umbrella is deployed at the first level, it can be used by one person, and after the umbrella is deployed at the second level, it can be used by multiple people. Folding umbrella that is easy to arrange: the umbrella surface is connected with the umbrella frame, there is a groove at the top of the umbrella, the groove is made of magnet blocks, and the umbrella head at the end of the umbrella frame is made of metal material. When using the umbrella, you can use the magnet in the groove of the umbrella top to attract the umbrella head at the metal end of the umbrella frame, and then you can organize the umbrella surface. A folding umbrella whose diameter can be reduced by changing the structure of the umbrella frame: the bending part is bent toward the direction of the inner main bone, so that the sub-main bone is connected to the side of the inner main bone, so that after the umbrella structure is folded , the sub-main rib and the inner main rib are dislocated so as to effectively reduce the diameter of the umbrella rib structure. Folding umbrella that changes the angle of the outer pole to collect rainwater: the umbrella handle includes an upper umbrella handle, a lower umbrella handle and a sleeve for the middle pole of the umbrella handle, the upper umbrella handle is inserted into the upper end of the sleeve of the middle pole of the umbrella handle, and the lower umbrella handle is inserted into the umbrella handle The lower end of the middle rod casing and the outer support rod of the umbrella rib are horizontally inclined at a certain angle, which effectively solves the problems of wet, slippery and messy ground caused by the accumulated water on the umbrella surface flowing to the ground in rainy days. A foldable umbrella that is easy to fold: an umbrella pole, an upper umbrella nest fixed on the top of the umbrella pole, a lower umbrella nest slidably installed on the umbrella pole, a first rib hinged with the upper umbrella nest, a second umbrella hinged with the first rib Umbrella ribs, the lower umbrella ribs hinged between the lower umbrella nest and the first umbrella rib, the auxiliary ribs hinged between the second umbrella rib and the lower umbrella nest ribs, wherein the first umbrella rib, the second umbrella rib The umbrella ribs, the lower umbrella nest support ribs and the auxiliary umbrella ribs constitute a four-bar linkage mechanism, and the lower umbrella nest support ribs are provided with a pivot. When installing the folding umbrella with this structure, it is only necessary to hang the umbrella retracting spring on the hook of the auxiliary umbrella frame, which is convenient for the installation and disassembly of the umbrella retracting spring.

Summary: At present, there are few folding umbrellas that involve the adjustable surface of the umbrella, and most of the folding umbrellas are folded outward when they are folded, and they are easy to fold back when they are reversed and encounter wind.

Detailed ways

The technical solution of the present invention will be described in more detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the overall structure of the folding umbrella of the present invention is: comprising an umbrella pole 10, the umbrella pole 10 is connected with the sliding pair of the first sleeve 9, and it is characterized in that several A first umbrella rib 11, the umbrella pole 10 is provided with a first hinge 1 and a second hinge 2 in sequence from top to bottom, the first hinge 1 is hinged to the second rib 14, and the second hinge 2 is connected to the second rib 14. The third rib 13 is hinged, the second rib 14 and the third rib 13 are hinged through the fourth hinge 4 , and the first rib 11 and the third rib are hinged through the third hinge 3 . Fig. 2 is a partially enlarged view of the double hinge system in the secondary deployment mechanism. Its specific structure is: the end of the third rib 13 is also hinged with the fourth rib 15 through the fifth hinge 5, and the fourth rib 15 and the fifth rib 16 are hinged through the seventh hinge 8; The end of the second rib 14 is connected with the sliding pair of the second sleeve 6, and the fifth rib 16 is hinged with the sixth hinge 7 on the second sleeve 6 through the sixth rib 17. The function of the double hinge system formed by the hinge 7 and the seventh hinge 8 is to realize the inward folding and unfolding of the fifth rib 16 through the double action of the fourth rib 15 and the double hinge system. The umbrella pole 10 is respectively provided with a primary deployment control hole 18 and a secondary deployment control hole 19 . When the first sleeve 9 slides to the position of the primary expansion control hole 18, the primary expansion of the umbrella is realized, and when the first sleeve 9 slides to the position of the secondary expansion control hole 19, the secondary expansion of the umbrella is realized.

The action principle of the first-level deployment state of the device of the present invention is shown in Figure 3. When the first sleeve 9 slides upward along the umbrella pole 10 to the position of the first-level deployment control hole 18, the first sleeve 9 pushes the first umbrella rib 11 toward The outer side is unfolded, and at the same time, with the help of the third hinge 3, the first rib 11 further pushes the third rib 13 to expand upward, and then with the help of the fourth hinge 4, the third rib 13 further pushes the second rib 14 upward Outward stretching realizes the first-level unfolding of the folding umbrella. In this process, because the second umbrella rib 14 is longer than the third umbrella rib 13, the end part of the third umbrella rib 13 gradually extends into the second sleeve 6 during the unfolding process, until it touches the bottom of the second sleeve 6 At this time, the fourth rib 15 and the fifth rib 16 still keep their original positions. Now the umbrella surface has a small area because of the inward folding of the fifth umbrella rib 16, and the wind resistance is also small, so it is suitable for single use when the wind is strong.

The action principle of the second-stage unfolded state of the device of the present invention is shown in FIG. At the same time, the first sleeve 9 pushes the first umbrella rib 11 and drives the third umbrella rib 13 to further expand upwards, and then with the help of the fifth hinge 5, the third umbrella rib 13 then drives the fourth umbrella rib 15 to expand upwards. At the same time, because the second rib 14 has withstood the bottom of the second sleeve 6 and remains still, so under the action of the double hinge system, the fourth rib 15 drives the fifth rib 16 outward through the sixth rib 17. Expand, and finally realize the secondary expansion of the folding umbrella. At this time, the area of the umbrella surface is large, and the umbrella surface is protected by the dual support and protection of the first-level and second-level expansion ribs, which greatly improves its bending resistance when it is subjected to reverse wind.
