Description

Technical Field

[0001] The utility model relates to the technical field of rain gear, in particular to an inflatable sunny and rainy umbrella which is convenient to fold and open. Background Art

[0002] At present, the handles and ribs of conventional sun umbrellas and outdoor umbrellas are usually made of materials such as steel wire and plastic to form a relatively stable supporting structure to achieve the function of shielding ultraviolet rays or rain.

[0003] Because it is necessary to ensure that the umbrella has sufficient support strength to protect against strong winds and heavy rains, in the prior art, the structure of an umbrella is generally complicated and has many parts, which results in a large volume and weight, and a high production cost. Although many umbrellas adopt a folding structure, they still take up a large space when folded. Therefore, many people generally do not like to carry umbrellas with them in pursuit of convenience. In addition, when an umbrella is worn out, it is difficult to disassemble it due to its structural design, and it is impossible to complete the garbage sorting and recycling well. It is often abandoned in a garbage dump and incinerated or landfilled as a whole, and has poor environmental performance.

[0004] In the prior art, in addition to conventional umbrella structures, in order to pursue the lightness of umbrellas and save materials, many design ideas for inflatable umbrellas have emerged. For example, Chinese patent CN202222600955.3 discloses a cap-type inflatable umbrella. In this technical solution, although the design idea of ​​using an inflation pipe to support the formation of a cap umbrella body is disclosed, it is not possible to complete the umbrella folding action well. After use, the user generally releases the gas in the umbrella, and then directly squeezes the deflated umbrella body into a ball for storage. This way of folding the umbrella not only lacks aesthetics, but also easily causes the various structures of the umbrella to wrinkle or even be damaged, making it impossible to use it again. It is difficult to obtain consumer recognition. Therefore, it is necessary to develop a simpler and more practical inflatable umbrella. Utility Model Content

[0005] In order to solve the above problems, the utility model provides an inflatable sunny and rainy umbrella which is convenient to fold and open.

[0006] The technical solution adopted by the utility model is: an inflatable umbrella that is easy to fold and support, comprising:

[0007] The umbrella handle is hollow inside and has an inflation head at one end;

[0008] A plurality of branch pipes are installed at one end of the umbrella handle away from the inflation head and are arranged around the circumference of the umbrella handle at intervals. The branch pipes are hollow inside and communicate with the inside of the umbrella handle. The branch pipes are made of flexible material.

[0009] The elastic thin strip is made of elastic material and is fixed on the branch tube along the extension direction of the branch tube. The branch tube and the elastic thin strip together constitute the umbrella rib;

[0010] The umbrella cloth is connected between two adjacent branch pipes;

[0011] The umbrella has a folded state and an opened state. In the folded state, the elastic thin band, the branch tube and the umbrella cloth are all rolled up; in the opened state, the umbrella handle and the branch tube are both inflated, the branch tube is tightened into a columnar pipe, and the elastic thin band and the umbrella cloth are unfolded along the extension direction of the branch tube.

[0012] Several optional methods are also provided below, but they are not intended to be additional limitations on the above-mentioned overall solution, but are merely further supplements or preferences. Under the premise that there are no technical or logical contradictions, each optional method can be combined with the above-mentioned overall solution separately, and multiple optional methods can also be combined.

[0013] Preferably, the elastic thin band is fixedly attached to the inner rolled side of the branch pipe.

[0014] Preferably, a plurality of the branch tubes are evenly spaced apart along the circumference of the umbrella handle.

[0015] Preferably, the umbrella handle is made of a flexible material and is provided with a folding structure along its extension direction. In the folded state, the umbrella handle is folded into a pancake shape, and in the expanded state, the umbrella handle is inflated and expanded into a straight column shape.

[0016] Preferably, the umbrella handle is made of a flexible material, and in the opened state, the umbrella handle is inflated and opened into a straight column shape.

[0017] Preferably, the umbrella handle is made of a hard material, and a telescopic structure for assisting the umbrella handle to extend or contract is provided on the umbrella handle.

[0018] Preferably, an umbrella tail tip is provided at one end of the umbrella handle away from the inflation head, and in the expanded state, the umbrella tail tip is located above the branch tube and the umbrella cloth.

[0019] More preferably, the elastic thin band and the branch tube are of equal length.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] 1. The branch tube is made of flexible material and equipped with an elastic thin belt. When the branch tube is folded, the gas in the branch tube is released, the internal air pressure is reduced, and the elastic thin belt will drive the branch tube to automatically shrink to a state of rolling up around the axis, which can not only quickly drive the umbrella cloth to fold, but also the overall volume after folding is as small as a handful (in the folded state, the umbrella handle can also be folded and compressed, occupying little space). It is very light and very convenient to carry when going out, and can be easily put into a lady's small bag;

[0022] 2. When the umbrella needs to be opened, the air is inflated into the umbrella handle and the branch tube through the inflating head. After the branch tube is inflated, the branch tube, which is one of the components of the umbrella ribs, is in a rolled-up state. As air is continuously pressed into the branch tube, all the possible columnar spaces expand and tend to form a taut and straightened long column. This expansion force drives the elastic thin belt to be straightened along with the branch tube. At this time, the umbrella cloth is also unfolded synchronously, and the umbrella can be opened. After the umbrella is opened, the inflating head is blocked and the overall structure is stable;

[0023] 3. Since only the umbrella handle and branch tube need to be inflated, the amount of air required to open the umbrella is relatively small. As long as the amount of air is not large, it can be quickly opened to become an outdoor umbrella;

[0024] 4. The whole is made of flexible and elastic materials. When the umbrella is old or damaged, it can be simply disassembled and classified for recycling, which is conducive to the reuse of resources and has good environmental protection performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Specific implementation plan: see Figure 1-Figure 7 The utility model is an inflatable umbrella that is easy to fold and support, comprising:

[0039] The umbrella handle 1 is hollow inside and has an inflation head 4 at one end;

[0040] A plurality of branch pipes 2 are installed at one end of the umbrella handle 1 away from the inflation head 4 and are arranged around the circumference of the umbrella handle 1 at intervals. The branch pipes 2 are hollow inside and communicate with the inside of the umbrella handle 1. The branch pipes 2 are made of flexible material.

[0041] The elastic thin strip 3 is made of elastic material and is fixed on the branch tube 2 along the extension direction of the branch tube 2. The branch tube 2 and the elastic thin strip 3 together constitute the umbrella ribs;

[0042] The umbrella cloth 5 is connected between two adjacent branch pipes 2;

[0043] The umbrella has a folded state and an opened state. In the folded state, the elastic thin strip 3, the branch tube 2 and the umbrella cloth 5 are all rolled up; in the opened state, the umbrella handle 1 and the branch tube 2 are inflated, the branch tube 2 is tightened into a columnar pipe, and the elastic thin strip 3 and the umbrella cloth 5 are unfolded along the extension direction of the branch tube 2.

[0044] As a preferred implementation of this embodiment, the elastic thin strip 3 is fixedly attached to the inner rolled side of the branch tube 2. With this design, when the umbrella switches from the open state to the folded state on a sunny day, the elastic thin strip 3 can better drive the branch tube 2 to roll up around the axis.

[0045] In addition, in this embodiment, the elastic thin strip 3 can be selectively set on the inner wall of the branch pipe 2 (of course, it can also be set on the outer wall of the branch pipe 2). This design can, on the one hand, hide the elastic thin strip 3 and improve the aesthetics. On the other hand, the elastic thin strip 3 is not easily damaged and has a longer service life.

[0046] Also, see Figure 4 and Figure 6 It can be seen that in this embodiment, a plurality of branch tubes 2 are evenly spaced apart along the circumference of the umbrella handle 1 .

[0047] In this embodiment, the umbrella handle 1 is made of a flexible material and is provided with a folding structure along its extension direction. In the folded state, the umbrella handle 1 is folded into a pancake shape, and in the opened state, the umbrella handle 1 is inflated and opened into a straight column shape.

[0048] Here, after the umbrella handle 1 is inflated through the inflation head 4, since the umbrella handle 1 adopts a folding structure, please refer to Figure 1-Figure 3 It can be seen that when the air pressure in the umbrella handle 1 increases, it will squeeze the inner wall of the umbrella handle 1, so that the folding structure gradually expands and stretches, until the outside of the umbrella handle 1 becomes smooth. At this time, the umbrella handle 1 is formed into a straight column, which is convenient for users to hold. When the air in the umbrella handle 1 is released, the air pressure in the umbrella handle 1 decreases and cannot support the inner wall of the umbrella handle 1. Since the umbrella handle 1 is made of a flexible material, the umbrella handle 1 can be deformed. At this time, the user can squeeze the umbrella handle 1 with his hands to compress it into a pancake shape, which takes up little space.

[0049] In addition, the umbrella handle 1 can also be made of a flexible material, and in the open state, the umbrella handle 1 is inflated and opened into a straight column. Here, there is no folding structure designed on the umbrella handle 1. When the air in the umbrella handle 1 is released, the umbrella handle 1 can be directly rolled up or folded to complete storage.

[0050] As another preferred implementation manner of this embodiment, the umbrella handle 1 is made of a hard material, and a telescopic structure for assisting the umbrella handle 1 to extend or contract is provided on the umbrella handle 1.

[0051] Here, when the umbrella handle 1 is made of a hard material, such as stainless steel or plastic, a telescopic structure of a conventional umbrella is adopted, which is a prior art and will not be described in detail here.

[0052] In addition, a return spring may also be designed on the umbrella handle 1 to realize the opening and contraction of the umbrella handle 1. This structural design is also a conventional structure and will not be described in detail here.

[0053] See also Figure 4 It can be seen that in this embodiment, an umbrella tail tip 6 is provided at one end of the umbrella handle 1 away from the inflation head 4. In the expanded state, the umbrella tail tip 6 is located above the branch tube 2 and the umbrella cloth 5.

[0054] Here, the tail tip 6 of the umbrella is made of a flexible material. When the umbrella handle 1 and the branch tube 2 are inflated, the tail tip 6 of the umbrella will also be inflated.

[0055] More specifically, in order to better achieve synchronous curling and unfolding of the branch tube 2 and the elastic thin band 3, in the present embodiment, the elastic thin band 3 and the branch tube 2 are of the same length, or substantially of the same length.

[0056] Note that in this embodiment, the elastic thin strip 3 is similar to a coil spring (a type of spring), see Figure 1 It can be seen that when no external force is applied, it has the characteristics of a coil spring - it rolls up around the center, and after being pulled apart by external force and stretched, it can automatically roll back to the original state of curling around the axis, like a tape measure, by the internal force of the microstructure. Since the elastic thin strip 3 and the branch tube 2 are substantially the same length, and are fixed to the inner wall of the branch tube 2 along the extension direction of the branch tube 2, when the elastic thin strip 3 rolls up around the center, the branch tube 2 will also be rolled up with the elastic thin strip 3, and since the umbrella cloth 5 is connected between two adjacent branch tubes 2, it will also drive the umbrella cloth 5 to roll up into a small ball.

[0057] For ease of understanding, the working principles of the parachute opening and closing processes are explained below:

[0058] About the principle of parachute opening process:

[0059] When the umbrella needs to be opened, air is inflated into the umbrella handle 1 through the inflation head 4. Since each branch pipe 2 is connected to the inside of the umbrella handle 1, the branch pipe 2 is also gradually inflated with air. Figure 1-Figure 5 It can be seen that in this process, all the possible dilated cylindrical spaces in the branch tube 2 expand and tend to form a long, taut, straightened column. In addition, since the expansion force of the branch tube 2 fully stretched by the air expansion is greater than the torsional elastic force of the elastic band 3 itself, the elastic band 3 will also be stretched and straightened along with the branch tube 2. Figure 4 When all the umbrella handles 1 are expanded outward to a sufficient extent, the opening of the inflation head 4 is blocked with a cover to prevent the air in the umbrella handles 1 and the branch pipe 2 from leaking out, and the umbrella opening action can be completed.

[0060] About the principle of umbrella folding process:

[0061] When the umbrella needs to be folded, the cover on the inflation head 4 is opened, and the air in the umbrella handle 1 and the branch tube 2 is gradually released from the inflation head 4. The air pressure in the branch tube 2, which was originally expanded into a column due to inflation, gradually decreases. Since the air tube is made of flexible material, the inner wall of the air tube gradually becomes shriveled due to the loss of air pressure support. At this time, the inherent centripetal torsion elastic force of the elastic thin band 3, which is attached to the branch tube 2 after being pulled apart by external force, is the same length as the branch tube 2, and has a spring-like nature, begins to gradually appear. When this torsion force is greater than the air pressure expansion force that supports the branch tube to form a column, the elastic thin band 3 begins to curl around the center and shrink and restore, and drives the shriveled branch tube 2 to curl together. Since the umbrella cloth 5 is connected between two adjacent branch tubes 2, the umbrella cloth 5 will also shrink into a small ball at the same time.

[0062] In addition, when the air in the umbrella handle 1 is released, the air expansion force supporting the umbrella handle 1 into a column weakens and disappears. The user can pat the umbrella handle 1 lightly with his hands, and the umbrella handle 1 can be compressed into a pancake shape through the folding structure, occupying very little space.

[0063] In this way, the opening and closing of the umbrella is completed between the filling and releasing of air in the umbrella handle 1 and the branch pipe 2, which is very convenient to use and carry, and has good environmental protection performance.

[0064] The above description of an inflatable sun umbrella that is easy to fold and support of the utility model is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the inventive concept of the utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the utility model.
