Abstract
Description
Technical Field
[0001] This utility model relates to the field of hat technology, and in particular to a hat with an inflatable umbrella. Background Technology
[0002] Currently, the handles and ribs of conventional umbrellas and outdoor umbrellas are usually made of materials such as steel wire and plastic to form a relatively stable support structure, thereby achieving the function of blocking ultraviolet rays or rain.
[0003] Because conventional umbrellas use a lot of materials and have a complex structure, many people prefer convenience and don't like to carry them. Furthermore, once an umbrella is old and worn out, its design makes it difficult to disassemble and recycle, often resulting in it ending up in the trash or being incinerated or landfilled, which is environmentally unfriendly. In pursuit of lightweight and material-saving umbrellas, many inflatable umbrellas have appeared on the market. However, existing inflatable umbrellas don't fold properly, and after use, the air is usually released, and the deflated umbrella is simply squeezed into a ball for storage. This method is not only aesthetically unappealing but also easily causes wrinkles and damage to the umbrella's structure, rendering it unusable and unlikely to gain consumer acceptance.
[0004] To address the aforementioned technical issues, I previously applied for a utility model patent with patent number CN202421084482.9, entitled "An Inflatable Umbrella with Convenient Opening and Closing." This patent discloses how to more easily open and close the inflatable umbrella, preventing wrinkles and damage after folding. However, in practical application, I found that while the inflatable umbrella takes up little space when folded and is convenient for outdoor use, it still requires hand-holding. Since the inflatable umbrella is very light compared to a regular umbrella, many users report feeling awkward, as if holding a ball of air, and prolonged use can be tiring. Furthermore, when folding the umbrella, the handle uses a corrugated tube-like folding structure. After deflation, the user needs to squeeze the handle to compress it into a disc shape, which is cumbersome. Additionally, if there is rain on the handle, the hands are easily wetted. Utility Model Content
[0005] To solve the above problems, this utility model proposes a hat with an inflatable umbrella.
[0006] The technical solution adopted by this utility model is: a hat with an inflatable umbrella, comprising a hat and an inflatable umbrella, wherein the hat includes at least a hat body and a brim connected to each other, and the inflatable umbrella includes:
[0007] The umbrella handle is hollow inside and has a first elastic strip fixedly attached to it in its extending direction. One end of the umbrella handle is fixed to the brim. Several branch tubes are installed at the free end of the umbrella handle and are arranged circumferentially around the free end. The branch tubes are hollow inside and communicate with the inside of the umbrella handle. A second elastic strip is fixedly attached to each branch tube in its extending direction. Both the first and second elastic strips are made of elastic material, and both the branch tubes and the umbrella handle are made of flexible material.
[0008] The umbrella fabric is connected between two adjacent branch pipes;
[0009] An inflation / deflation assembly is located on one side of the umbrella handle;
[0010] The inflatable umbrella has a folded state and an open state. In the folded state, the umbrella handle, the first elastic band, the branch tube, the second elastic band, and the umbrella fabric are all rolled up. In the open state, the umbrella handle and the branch tube are both inflated and taut into cylindrical tubes. The first elastic band is unfolded along the extension direction of the umbrella handle, and the second elastic band and the umbrella fabric are unfolded along the extension direction of the branch tube.
[0011] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.
[0012] Preferably, the first elastic strip is fixedly attached to the inward-curling side of the umbrella handle, and the second elastic strip is fixedly attached to the inward-curling side of the branch tube.
[0013] Preferably, a plurality of the branch pipes are arranged at uniform intervals along the circumference of the free end of the umbrella handle.
[0014] Preferably, the inflation / deflation assembly includes:
[0015] An inflation / deflation tube is attached at one end to the base of the umbrella handle;
[0016] An air nozzle is located at the end of the inflation / deflation tube furthest from the umbrella handle.
[0017] Preferably, at least one of the air inlet / outlet tube and the umbrella handle, and the air nozzle and the air inlet / outlet tube, is a detachable structure.
[0018] Preferably, during the transition from the closed state to the open state, part of the inflation / deflation tube is placed flat above the brim, and the air nozzle extends below the brim following the free end of the inflation / deflation tube, allowing the user to blow air.
[0019] Preferably, at least two branch pipes are provided with support pipes, one end of which is connected to the branch pipe and the other end is closed, and the cap is provided with fasteners for cooperating with and securing the support pipes through.
[0020] Preferably, in the open state, at least two of the plurality of supporting pipes are arranged on opposite sides of the cap body.
[0021] Preferably, the first elastic strip and the umbrella handle are of the same length.
[0022] More preferably, the second elastic strip and the branch tube are of equal length.
[0023] Compared with the prior art, this utility model has the following beneficial effects:
[0024] 1. The umbrella handle and branch tube are made of flexible material, with a first elastic thin strip and a second elastic thin strip. Referring to the blow-drum toy, when the umbrella is closed, the gas in the handle and branch tube is released, the internal air pressure decreases, the first elastic thin strip will cause the umbrella handle to automatically curl up around the axis, and the second elastic thin strip will cause the branch tube to automatically curl up around the axis, and the umbrella fabric will also be closed. When closed, the overall volume is so small that it can be held in one hand, and it will not look obtrusive when placed on top of a hat.
[0025] 2. The inflatable umbrella cleverly combines a hat and an inflatable umbrella. When going outdoors, people usually wear hats to shield themselves from the sun. When they need better sun protection or when it starts to rain, they can inflate the handle and tubes through the inflation / deflation mechanism. As air is continuously pushed into the handle and tubes, which are in a rolled-up state, all the possible cylindrical spaces expand and tend to form a taut and straight long column. This expansion force will cause the first elastic band to straighten along with the handle and the second elastic band to straighten along with the tubes. At the same time, the umbrella fabric also unfolds, thus opening the umbrella. The umbrella can be opened and closed without holding it, freeing up your hands in rainy or sunny conditions. Moreover, because it is an inflatable umbrella, it is very lightweight and will not put any weight on the head.
[0026] 3. Since only the umbrella handle and support tube need to be inflated, the amount of air required to open the umbrella is relatively small. With just a small amount of air, it can be quickly opened into an outdoor umbrella. Attached Figure Description

[0041] For detailed implementation plans, please refer to... Figures 1-7 This utility model is a hat with an inflatable umbrella, including a hat 1 and an inflatable umbrella, wherein the hat 1 includes at least a hat body 11 and a brim 12 connected to each other, and the inflatable umbrella includes:
[0042] The umbrella handle 2 is hollow inside and has a first elastic thin strip 3 fixedly attached to it in its own extending direction. One end of the umbrella handle 2 is fixed to the brim 12.
[0043] Several branch tubes 5 are installed at the free end of the umbrella handle 2 and are arranged around the free end at intervals. The branch tubes 5 are hollow inside and communicate with the inside of the umbrella handle 2. A second elastic thin strip 6 is fixedly attached to the branch tubes 5 in its own extension direction. The first elastic thin strip 3 and the second elastic thin strip 6 are both elastic materials, and the branch tubes 5 and the umbrella handle 2 are both flexible materials.
[0044] The umbrella fabric 7 is connected between two adjacent branch pipes 5;
[0045] The inflation / deflation assembly 4 is located on one side of the umbrella handle 2;
[0046] The inflatable umbrella has a folded state and an open state. In the folded state, the umbrella handle 2, the first elastic band 3, the branch tube 5, the second elastic band 6, and the umbrella fabric 7 are all rolled up. In the open state, the umbrella handle 2 and the branch tube 5 are both inflated, and the umbrella handle 2 and the branch tube 5 are taut into cylindrical tubes. The first elastic band 3 is unfolded along the extension direction of the umbrella handle 2, and the second elastic band 6 and the umbrella fabric 7 are unfolded along the extension direction of the branch tube 5.
[0047] The umbrella handle 2, branch tube 5, first elastic band 3, second elastic band 6, and umbrella fabric 7 described above together constitute an inflatable umbrella. That is to say, when opened, it is equivalent to placing a stable inflatable umbrella above the hat 1. Among them, the branch tube 5 and the second elastic band 6 together constitute the umbrella ribs of the inflatable umbrella.
[0048] Regarding the fixed connection between the umbrella handle 2 and the brim 12, a connecting part can be provided at the lower end of the umbrella handle 2, and this connecting part can be directly sewn to the brim 12. Alternatively, a fixing seat can be provided above the brim 12, and a connecting block can be provided at the lower end of the umbrella handle 2, with the connecting block detachably installed on the fixing seat. The detachable connection structure of the fixing seat and the connecting block can be selected by threaded connection, magnetic connection, or snap-on connection, etc., which are existing technologies and will not be described in detail here.
[0049] When the umbrella handle 2 and the brim 12 are detachably connected, the inflatable umbrella can be removed from the brim 12 when not in use, deflated, folded and stored, covered with a plastic bag, and placed directly into a pocket of clothing or pants, and taken out whenever needed.
[0050] In a preferred embodiment of this invention, the first elastic strip 3 is fixedly attached to the inward-curling side of the umbrella handle 2, and the second elastic strip 6 is fixedly attached to the inward-curling side of the branch tube 5. This design allows the first elastic strip 3 to better drive the umbrella handle 2 to roll around the axis during the transition from the inflatable umbrella's open state to its closed state, and the second elastic strip 6 to better drive the branch tube 5 to roll around the axis.
[0051] In addition, in this embodiment, the first elastic thin strip 3 can be optionally disposed on the inner wall of the umbrella handle 2 (or on the outer wall of the umbrella handle 2), and the second elastic thin strip 6 can be optionally disposed on the inner wall of the branch pipe 5 (or on the outer wall of the branch pipe 5). This design can hide the first elastic thin strip 3 and the second elastic thin strip 6, resulting in better aesthetics. On the other hand, the first elastic thin strip 3 and the second elastic thin strip 6 are not easily damaged and have a longer service life.
[0052] In addition, please see Figure 1 and Figure 6 As can be seen, in this embodiment, several branch pipes 5 are arranged at uniform intervals along the circumference of the free end of the umbrella handle 2.
[0053] Next, please refer to Figure 1 As can be seen, in this embodiment, the inflation / deflation assembly 4 includes:
[0054] The inflation / deflation tube 41 is connected at one end to the base of the umbrella handle 2;
[0055] The air nozzle 42 is located at the end of the inflation / deflation pipe 41 away from the umbrella handle 2.
[0056] Furthermore, in this embodiment, at least one of the following structures is detachable: the inflation / deflation tube 41 and the umbrella handle 2, and the air nozzle 42 and the inflation / deflation tube 41.
[0057] Then, in this embodiment, during the process of switching from the closed state to the open state, part of the inflation / deflation tube 41 is placed flat above the brim 12, and the air nozzle 42 extends below the brim 12 along with the free end of the inflation / deflation tube 41, allowing the user to blow air.
[0058] Regarding the inflation / deflation assembly 4, it can be chosen as a separate accessory. When the inflation / deflation assembly 4 is a separate accessory, it is disassembled and installed onto the umbrella handle 2 as a whole. For example, a plug can be installed at one end of the inflation / deflation tube 41, and a socket can be installed on the umbrella handle 2, with a plug hinged to the socket. When inflation is needed, the plug is opened, and the plug is matched and inserted into the socket, thus assembling the inflation / deflation tube 41 and the umbrella handle 2 (not shown in the figure). At this time, the user can inflate the inside of the umbrella handle 2 through the air nozzle 42. After inflation, if you do not want the inflation / deflation assembly 4 to affect the appearance or the wearing of the hat 1, you can choose to remove the inflation / deflation assembly 4 and reseal the socket with the plug.
[0059] Of course, the above operations generally require removing the hat 1. To make inflation and deflation more convenient and without removing the hat 1, in this embodiment, the inflation / deflation component 4 can be directly fixed to the umbrella handle 2. The air nozzle 42 is provided with a plug. After removing the plug, the inside of the umbrella handle 2 can be inflated through the air nozzle 42. After inflation is completed, the air nozzle 42 is sealed with the plug.
[0060] Regarding the inflation of the valve 42, you can choose to simply blow air in with your mouth, or you can use an air pump or an air compressor. Since only the umbrella handle 2 and the branch tube 5 need to be inflated, the amount of air needed to open the umbrella is relatively small. In general, it is most convenient to inflate the valve 42 directly with your mouth.
[0061] In addition, to ensure the cleanliness and hygiene of the air nozzle 42, in this embodiment, the air nozzle 42 needs to be designed as a detachable movable air nozzle 42. After use, the air nozzle 42 needs to be removed from the inflation / deflation tube 41, soaked in boiling water or cleaned in various food-grade detergents, and then reinstalled back onto the inflation / deflation tube 41.
[0062] Next, please refer to Figure 1 and Figure 2 As can be seen in this embodiment, at least two branch pipes 5 are provided with support pipes 8. One end of the support pipe 8 is connected to the branch pipe 5, and the other end is closed. The cap body 11 is provided with fasteners 13 for cooperating with and fixing the support pipes 8 through which they pass. In the open state, among the plurality of support pipes 8, at least two support pipes 8 are arranged on opposite sides of the cap body 11.
[0063] In this embodiment, the fastener 13 is a buckle, one end of which is fixed to the cap body 11, and the other end is connected to the cap body 11 by a snap fastener or Velcro.
[0064] When the umbrella is in the open position, the air entering the branch tube 5 continues to flow into the support tube 8, tautning it into a straight column. At this point, the user can unfasten the strap, place the support tube 8 inside the strap, and then re-secure the strap to the cap body 11 to complete the fixation of the support tube 8. The design of the support tube 8 enhances the overall structural stability of the inflatable umbrella, thus giving it better wind and rain resistance.
[0065] More specifically, in order to better achieve synchronous retraction and deployment of the umbrella handle 2 and the first elastic thin strip 3, as well as synchronous retraction and deployment of the branch tube 5 and the second elastic thin strip 6, in this embodiment, the first elastic thin strip 3 and the umbrella handle 2 are of equal length, and the second elastic thin strip 6 and the branch tube 5 are of equal length.
[0066] Note that in this embodiment, both the first elastic strip 3 and the second elastic strip 6 are similar to a coil spring (a type of clockwork). Please refer to [link / reference]. Figure 2 As can be seen, when no external force is applied, it has the characteristics of a coil spring—it rolls up around the center, and after being stretched out by an external force, it can automatically roll back to its original coiled state around the axis, just like a measuring tape, based on the principle of "elastic deformation" and the internal forces of its microstructure.
[0067] Since the first elastic band 3 is the same length as the umbrella handle 2 and is fixed to the inner wall of the umbrella handle 2 along its own extension direction, when the first elastic band 3 is rolled up around the center, the umbrella handle 2 will also be rolled up along with the first elastic band 3. Since the second elastic band 6 is approximately the same length as the branch tube 5 and is fixed to the inner wall of the branch tube 5 along its own extension direction, when the second elastic band 6 is rolled up around the center, the branch tube 5 will also be rolled up along with the second elastic band 6. Since the umbrella fabric 7 is connected between two adjacent branch tubes 5, it will also cause the umbrella fabric 7 to curl up into a small ball.
[0068] To make it easier to understand, the working principles of the umbrella opening and closing processes are explained below:
[0069] Explanation of the principle behind the umbrella opening process:
[0070] When the umbrella needs to be opened, air is pumped into the handle 2 via the inflation / deflation assembly 4. Since the branch pipes 5 are connected to the inside of the handle 2, air is also gradually pumped into the branch pipes 5. (Please refer to...) Figures 2-7 As can be seen, during this process, all possible expandable cylindrical spaces in the umbrella handle 2 and branch tube 5 expand, continuously tending to form a taut and straightened long column. Furthermore, because the expansion force of the umbrella handle 2 due to air expansion is greater than the torsional elastic force of the first elastic band 3, and the expansion force of the branch tube 5 due to its full extension is greater than the torsional elastic force of the second elastic band 6, the first elastic band 3 will taut and straighten along with the umbrella handle 2, and the second elastic band 6 will taut and straighten along with the branch tube 5. Please refer to... Figure 4 Once all the umbrella handles 2 have been extended to a sufficient extent, use the plug to seal the opening of the air nozzle 42 or the socket (described in detail above) to prevent air from leaking out of the umbrella handles 2 and the branch tubes 5, thus completing the opening action of the umbrella.
[0071] Explanation of the principle behind the umbrella closing process:
[0072] When the umbrella needs to be closed, open the air valve 42 or the plug on the socket. At this time, the air in the umbrella handle 2 and the branch tube 5 is gradually released from the inflation head. The air pressure in the umbrella handle 2 and the branch tube 5, which were originally expanded into a column shape due to inflation, gradually decreases. Since the umbrella handle 2 and the air tube are made of flexible material, the inner walls of the umbrella handle 2 and the air tube gradually become deflated due to the loss of air pressure support. At this point, the inherent centripetal torsional elasticity of the first elastic thin strip 3, which is attached to the umbrella handle 2 after being pulled open by external force, is the same length as the umbrella handle 2, and has a similar property to a spring. When this torsional force is greater than the air pressure expansion force that supports the roll to form a column, the first elastic thin strip 3 begins to curl back and retract around the center, and drives the umbrella handle 2, which has become shriveled, to curl back as well. Similarly, at this time, the second elastic thin strip 6 begins to curl back and retract around the center, and drives the branch tube 5, which has become shriveled, to curl back as well. Since the umbrella fabric 7 is connected between two adjacent branch tubes 5, the umbrella fabric 7 will also curl back into a small ball at the same time.
[0073] Note that the umbrella handle 2 achieves its curled-back shape through the torsional elasticity of the first elastic band 3, and the branch tube 5 achieves its curled-back shape through the torsional elasticity of the second elastic band 6. In practical applications, the first elastic band 3 can be omitted from the umbrella handle 2, and the second elastic band 6 can be omitted from the branch tube 5; it is sufficient that the material of the umbrella handle 2 or the branch tube 5 itself has a certain automatic curling-back characteristic. For example, the umbrella handle 2 and the branch tube 5 can be made of flexible materials, and after both are heat-pressed into shape, they will have an automatic curling-back function.
[0074] Please see Figure 8When the hat 1 in this embodiment is worn and the inflatable umbrella is opened, the multiple branch tubes 5 located at the rear end extend backward to a certain extent when walking in the rain, forming a cape-like effect. When people walk in the rain, this structure can guide the wind and the umbrella, thereby making the umbrella's support structure more stable and less prone to deformation due to rain or wind.
[0075] The above description of a hat with an inflatable umbrella is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. All equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
