Description

Technical Field

[0001] This invention relates to the field of outdoor umbrella technology, specifically to an umbrella canopy structure and an outdoor umbrella using the same. Background Technology

[0002] Outdoor umbrellas are widely used in scenic squares, commercial streets, riverside walkways, and other scenarios. They typically consist of eight roughly fan-shaped pieces of fabric pieced together to form a nearly circular, enclosed canopy (here, "enclosed" means there is no direct passage between the inner and outer sides of the canopy, not that the canopy is spherically enclosed). However, this canopy structure has significant drawbacks: 1. The sealed umbrella canopy is shaped like a spherical crown. In windy weather, a pressure difference will be formed on the upper and lower sides of the canopy, resulting in the Bernoulli effect. This can easily cause the entire umbrella to overturn, the umbrella ribs to twist and break, etc., resulting in poor stability when used outdoors. 2. Traditional umbrellas only provide basic sunshade and rain protection, and cannot accommodate advertising areas for commercial use, making them unsuitable for the design requirements of integrated commercial umbrellas for selling trendy toys and blind boxes.

[0003] Currently, there are some umbrella structures that can withstand wind, but these windproof umbrellas usually have complex rib structures, resulting in very high overall manufacturing, transportation, and storage costs. Moreover, they cannot be repaired or modified from existing outdoor umbrellas; they can only be upgraded and replaced entirely, which is very costly. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an umbrella structure that offers advantages such as strong wind resistance, good rain and sun protection, and low cost.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an umbrella structure comprising multiple independent, approximately triangular umbrella slats, which are joined together to form an approximately circular umbrella surface. The umbrella slats are characterized by having at least one pressure relief window, and a rainproof eaves are connected to the umbrella slats, with the rainproof eaves covering the pressure relief windows. When the rainproof eaves cover the pressure relief window, an airflow channel is still maintained at the pressure relief window for air to flow between the inside and outside of the umbrella.

[0006] When it is raining, the rainproof eaves cover the pressure relief window to prevent rainwater from entering the umbrella through the pressure relief window.

[0007] Its beneficial effects are as follows: In strong winds, the airflow channel through the pressure relief window balances wind pressure, allowing air to circulate inside and outside the umbrella, effectively counteracting the Bernoulli effect. This enables the umbrella to stably withstand winds of at least force 8, reducing deformation and damage to outdoor umbrellas. Simultaneously, in rainy conditions, the rainproof eaves cover the pressure relief window to prevent rainwater from entering the umbrella. Furthermore, in strong sunlight, the rainproof eaves cover the pressure relief window to prevent intense sunlight from entering the umbrella. The rainproof eaves compensate for the shortcomings of the pressure relief window opening, ensuring that the functions of sunshade, ventilation, and rain protection do not conflict.

[0008] Meanwhile, the umbrella structure of this patent adopts the traditional segmented processing technology of umbrellas, only adding the process of opening windows and setting rainproof eaves, without making significant changes to the original process, resulting in lower production costs.

[0009] Furthermore, the umbrella canopy structure of this patent can be directly used to replace the canopy of traditional outdoor umbrellas, modifying existing outdoor umbrellas to enhance their wind resistance. Even if the canopy is damaged, it can be directly replaced. The overall manufacturing, storage, transportation, and installation costs will be very low.

[0010] In some embodiments, the umbrella slats have two pressure relief windows, namely a first pressure relief window and a second pressure relief window. The first pressure relief window is located near the center of the umbrella surface, and the second pressure relief window is located away from the center of the umbrella surface.

[0011] Its beneficial effect is that the double pressure relief window design allows more airflow to pass through per unit time, thus resisting stronger winds. The double pressure relief window design can adapt to strong winds from more directions, improving stability.

[0012] In some embodiments, both the first and second pressure relief windows are horizontally arranged groove-shaped structures, and the length of the second pressure relief window is greater than the length of the first pressure relief window.

[0013] The beneficial effect is that the force is relatively smaller closer to the center of the umbrella surface and relatively larger further away from the center of the umbrella surface. Therefore, the length of the second pressure relief window is greater than that of the first pressure relief window. More airflow can pass through the second pressure relief window, which is far away from the center of the umbrella surface, thus maintaining the stability of the umbrella.

[0014] In some implementations, the pressure relief window is a horizontally arranged groove-shaped structure, and the rainproof eaves are long strip-shaped structures. The rainproof eaves are connected to the umbrella strips only on one side near the center of the umbrella surface; the other sides of the rainproof eaves are separate from the umbrella strips.

[0015] Its beneficial effect is that the long, strip-shaped rainproof eaves can just cover the horizontally set groove-shaped pressure relief window. Because only one side of the rainproof eaves is connected to the umbrella sheet near the center of the umbrella surface, while the other three sides are separate from the umbrella sheet, the rainproof eaves can be lifted up by the wind when strong winds come, thus facilitating air convection.

[0016] In some implementations, the edges of the pressure relief window are reinforced with locking structures, and the rainproof eaves are made of the same material as the umbrella slats.

[0017] Its beneficial effects include the ability of the seam reinforcement structure to prevent tearing of the umbrella fabric at the pressure relief window. Additionally, a thickened edging can be added to the outer edge of the umbrella slats, thereby improving the fabric's tear resistance and abrasion resistance.

[0018] In some embodiments, the pressure relief window is an approximately semi-circular or approximately semi-elliptical through-hole structure. The pressure relief window includes a horizontal side away from the center of the umbrella surface and an arc-shaped side close to the center of the umbrella surface. The rainproof eaves are connected to the arc-shaped side, and the unfolded area of ​​the rainproof eaves is larger than the area of ​​the pressure relief window. The rainproof eaves are separated from the horizontal side.

[0019] The beneficial effects are that the pressure relief window, with its near-semi-circular or near-elliptical through-hole structure, allows for a larger airflow channel, enabling greater airflow within the same timeframe and thus resisting stronger winds. Simultaneously, because the rainproof eaves are connected to the curved edge and have a large unfolded area, they better cover the pressure relief window during rain, and even in strong, level winds, the eaves will not be blown away from the top of the window. Furthermore, in strong winds, the eaves will be blown up, arching upwards and remaining directly above the pressure relief window, ensuring both the passage of large airflows and preventing rainwater from entering the umbrella through the window.

[0020] In some implementations, the umbrella comprises eight independent, approximately triangular umbrella panels, which are joined together to form an approximately circular umbrella surface.

[0021] Its advantage is that it can be adapted to the modification of most existing outdoor umbrellas.

[0022] In some embodiments, rivet mounting holes are provided on the sides of adjacent umbrella slats for connecting umbrella ribs, and display printing areas for printing advertisements are provided on the umbrella slats.

[0023] Its advantages include the ability to thread rivet holes for attaching straps to the umbrella ribs, enabling assembly or replacement. The display printing area can be used for printing advertisements, including promotional images and text for trendy toy brands and products, and is also suitable for commercial scenarios such as blind box sales in scenic areas.

[0024] The present invention also provides the following technical solution: an outdoor umbrella, comprising side posts, umbrella ribs, cantilever arms and the above-mentioned umbrella canopy structure, the umbrella canopy structure covering and connected to the umbrella ribs, one end of the cantilever arm being connected to the side posts, the other end of the cantilever arm being connected to the umbrella ribs, and the umbrella ribs covered with the umbrella canopy structure being located to the side of the side posts.

[0025] Its beneficial effects are that, after applying this umbrella fabric structure, it can be used in side-post umbrellas. The airflow channel at the pressure relief window can balance wind pressure, allowing air to circulate inside and outside the umbrella surface, thereby effectively counteracting the Bernoulli effect. This allows the umbrella to stably withstand winds of at least level 8, reducing deformation damage to outdoor umbrellas. The rainproof eaves compensate for the defects of the pressure relief window openings, ensuring that the functions of sunshade, ventilation, and rain protection do not conflict. Furthermore, the umbrella surface structure of this patent uses the traditional segmented processing technology for umbrella surfaces, only adding the steps of opening windows and setting rainproof eaves, without significantly changing the original process, resulting in lower production costs. Even if the umbrella fabric is damaged, it can be directly replaced. The overall manufacturing, storage, transportation, and installation costs will be very low.

[0026] The present invention also provides the following technical solution: an outdoor umbrella, comprising a pillar, umbrella ribs and an umbrella canopy structure as described above, the umbrella canopy structure covering and connected to the umbrella ribs, the umbrella ribs covered with the umbrella canopy structure being connected to the top of the pillar, and the pillar being located at the center of the umbrella canopy structure.

[0027] Its beneficial effects are that, after applying this umbrella fabric structure, it can be used in center-pole umbrellas. The airflow channel at the pressure relief window can balance wind pressure, allowing air to circulate inside and outside the umbrella surface, thus effectively counteracting the Bernoulli effect. This enables the umbrella to stably withstand winds of at least level 8, reducing deformation damage to outdoor umbrellas. The rainproof eaves compensate for the defects of the pressure relief window openings, ensuring that sunshade, ventilation, and rain protection functions do not conflict. Furthermore, this patented umbrella fabric structure uses the traditional segmented processing technology for umbrella fabrics, only adding the steps of opening windows and setting rainproof eaves, without significantly changing the original process, resulting in lower production costs. Even if the umbrella fabric is damaged, it can be directly replaced. The overall manufacturing, storage, transportation, and installation costs will be very low. Attached Figure Description

Detailed Implementation

[0029] As shown throughout the drawings, similar reference numerals denote similar or corresponding parts. While illustrative embodiments of this disclosure have been described and illustrated above, it should be understood that these are exemplary embodiments of this disclosure and not to be considered limiting. Additions, deletions, substitutions, and other modifications may be made to this invention without departing from the spirit and scope of this disclosure. Therefore, this disclosure is not limited to the descriptions below.

[0030] In this specification, the terms “including,” “comprising,” “comprising,” etc., shall always refer to a collection of objects, not limited to those specifically listed.

[0031] Figure 1-7 Preferred embodiments according to this disclosure are shown.

[0032] Example 1 like Figure 1 , 2 As shown in Figure 7, an umbrella canopy structure includes multiple independent, approximately triangular umbrella slats 1. These slats 1 are joined together to form an approximately circular umbrella canopy. The structure is characterized by having at least one pressure relief window 2 on each umbrella slat 1, and a rainproof eaves 3 connected to each umbrella slat 1, which covers the pressure relief window 2. When the rainproof eaves 3 cover the pressure relief window 2, the pressure relief window 2 still retains an airflow channel for air to flow between the inside and outside of the umbrella.

[0033] When it is raining, the rainproof eaves 3 cover the pressure relief window to prevent rainwater from entering the umbrella through the pressure relief window.

[0034] In strong winds, the airflow channel at the pressure relief window balances wind pressure, allowing air to circulate between the inside and outside of the umbrella, effectively counteracting the Bernoulli effect. This enables the umbrella to stably withstand winds of at least force 8, reducing deformation and damage. Simultaneously, in rainy conditions, the rainproof eaves 3 cover the pressure relief window to prevent rainwater from entering the umbrella. Furthermore, in strong sunlight, the rainproof eaves 3 cover the pressure relief window to prevent intense sunlight from entering the umbrella. The rainproof eaves 3 compensate for the shortcomings of the pressure relief window opening, ensuring that sunshade, ventilation, and rain protection functions do not conflict.

[0035] The umbrella structure of this patent follows the traditional segmented processing technology of umbrellas, only adding the steps of opening windows and setting rainproof eaves 3. It does not significantly change the original process and has a low production cost.

[0036] Furthermore, the umbrella canopy structure of this patent can be directly used to replace the canopy of traditional outdoor umbrellas, modifying existing outdoor umbrellas to enhance their wind resistance. Even if the canopy is damaged, it can be directly replaced. The overall manufacturing, storage, transportation, and installation costs will be very low.

[0037] like Figure 1 As shown, the umbrella slat 1 has two pressure relief windows, namely the first pressure relief window 21 and the second pressure relief window 22. The first pressure relief window 21 is located near the center of the umbrella surface, and the second pressure relief window 22 is located away from the center of the umbrella surface.

[0038] The double pressure relief window design allows for greater airflow per unit time, thus resisting stronger winds. This design also helps adapt to strong winds from more directions, improving stability.

[0039] The first pressure relief window 21 and the second pressure relief window 22 are both horizontally arranged groove structures, and the length of the second pressure relief window 22 is greater than the length of the first pressure relief window 21.

[0040] Because the force is relatively smaller closer to the center of the umbrella surface and relatively larger further away from the center, the second pressure relief window 22 is longer than the first pressure relief window 21. This allows more airflow to pass through the second pressure relief window 22, which is further away from the center of the umbrella surface, thus maintaining the stability of the umbrella. For example, the first pressure relief window 21 could be 15cm, and the second pressure relief window 22 could be 30cm.

[0041] like Figure 2 As shown in this patent, the pressure relief window is a horizontally arranged groove structure, and the rainproof eaves 3 is a long strip structure. The rainproof eaves 3 is connected to the umbrella sheet 1 only on one side near the center of the umbrella surface; the other sides of the rainproof eaves 3 are separate from the umbrella sheet 1.

[0042] Among them, the long strip-shaped rainproof eaves 3 can just cover the horizontally set groove-shaped pressure relief window. Because only one side of the rainproof eaves 3 near the center of the umbrella surface is connected to the umbrella sheet 1, while the other three sides are separate from the umbrella sheet 1, the rainproof eaves 3 can be lifted by the wind when strong winds come, thus achieving convenient air convection.

[0043] The rainproof eaves 3 should ideally be tilted downwards at an angle of 10° to 20°, with 15° being the most suitable. This allows rainwater to flow outwards along the eaves 3, preventing rainwater from entering the umbrella through the pressure relief window. This tilt also prevents the eaves 3 from being completely rolled up, thus protecting the pressure relief window from rainwater.

[0044] The rainproof eaves 3 and the triangular umbrella slats 1 of this patent are both made of the same material. A locking reinforcement structure 23 is provided at the edge of the pressure relief window, and the rainproof eaves 3 are made of the same material as the umbrella slats.

[0045] The edge-locking reinforcement structure 23 can prevent the umbrella fabric from tearing at the pressure relief window. At the same time, the outer edge of the umbrella slats 1 can be equipped with a thickened edging, thereby improving the tear resistance and abrasion resistance of the umbrella fabric.

[0046] This patent includes eight independent, approximately triangular umbrella panels 1, which are joined together to form an approximately circular umbrella surface. This design can be adapted to most existing outdoor umbrellas. The specific number of panels can be 6, 10, 12, etc., depending on the specific needs. The segmented umbrella panel structure allows for standardized mass production cutting, convenient disassembly and replacement, and reduced production and after-sales maintenance costs.

[0047] The sides of adjacent umbrella panels 1 are provided with rivet mounting holes 5, which are used to connect umbrella ribs 7. The umbrella panels 1 are provided with display printing areas for printing advertisements.

[0048] The rivet assembly hole 5 can be used to thread a strap to connect with the umbrella rib 7, thereby achieving assembly or replacement. The display printing area can be used to print advertisements, such as trendy toy brands and product promotional images and text, and can also be adapted to commercial scenarios such as blind box sales in scenic spots.

[0049] Of course, the umbrella slats of this patent have at least one pressure relief window, but can also have two or three. For example... Figure 7 As shown, there is only one pressure relief window on the umbrella slats. This window can also balance the wind pressure through the airflow channel, allowing air to circulate inside and outside the umbrella surface. This effectively counteracts the Bernoulli effect, enabling the umbrella to withstand at least level 8 gales and reducing deformation damage to outdoor umbrellas.

[0050] Example 2 like Figure 3 , 4 As shown, with Figure 1 , 2The difference in the first embodiment shown is that the pressure relief window in this embodiment is a through-hole structure that is approximately semi-circular or approximately semi-elliptical. The pressure relief window includes a horizontal edge 24 away from the center of the umbrella surface and an arc-shaped edge 25 close to the center of the umbrella surface. The rainproof eaves 3 are connected to the arc-shaped edge 25. The unfolded area of ​​the rainproof eaves 3 is larger than the area of ​​the pressure relief window. The rainproof eaves 3 are separated from the horizontal edge 24.

[0051] like Figure 4 As shown, the pressure relief window, with its approximately semi-circular or semi-elliptical through-hole structure, allows for a larger airflow channel, enabling greater airflow within the same timeframe and thus resisting stronger winds. Simultaneously, because the rainproof eaves 3 are connected to the curved edge 25 and have a large unfolded area, they effectively cover the pressure relief window during rain. Even in strong, level winds, the rainproof eaves 3 will not be blown away from the top of the pressure relief window. Furthermore, in strong winds, the rainproof eaves 3 will be blown up, arching upwards and remaining directly above the pressure relief window, ensuring both the passage of large airflows and preventing rainwater from entering the umbrella through the pressure relief window.

[0052] Of course, pressure relief windows can be horizontally arranged groove structures or through-hole structures that are approximately semi-circular or semi-elliptical, or they can also be circular, square, triangular, or hexagonal structures, as long as ventilation can be achieved inside and outside the canopy.

[0053] Example 3 like Figure 5 As shown, the present invention also provides the following technical solution: an outdoor umbrella with a side post 6, including a side post 6, an umbrella rib 7, a cantilever 8 and an umbrella canopy structure 4 as described above. The umbrella canopy structure 4 is covered and connected to the umbrella rib 7. One end of the cantilever 8 is connected to the side post 6, and the other end of the cantilever 8 is connected to the umbrella rib 7. The umbrella rib 7 covered with the umbrella canopy structure 4 is located to the side of the side post 6.

[0054] This umbrella fabric structure can be applied to side-post umbrellas. The airflow channel at the pressure relief window balances wind pressure, allowing air circulation between the inside and outside of the umbrella surface. This effectively counteracts the Bernoulli effect, enabling the umbrella to stably withstand winds of at least force 8 and reducing deformation damage. The rainproof eaves 3 compensate for the deficiencies of the pressure relief window opening, ensuring that sunshade, ventilation, and rain protection functions do not conflict. Furthermore, this patented umbrella fabric structure utilizes the traditional segmented processing technology, only adding the steps of opening the window and installing the rainproof eaves 3, without significantly altering the original process, resulting in lower production costs. Even if the umbrella fabric is damaged, it can be directly replaced. The overall manufacturing, storage, transportation, and installation costs are very low.

[0055] Example 4 like Figure 6As shown, the present invention also provides the following technical solution: a central pillar type outdoor umbrella, including a pillar 9, umbrella ribs 7 and the umbrella canopy structure 4 as described above, the umbrella canopy structure 4 covering and connected to the umbrella ribs 7, the umbrella ribs 7 covered with the umbrella canopy structure 4 being connected to the upper end of the pillar 9, and the pillar 9 being located at the center of the umbrella canopy structure 4.

[0056] This umbrella fabric structure can be applied to center-pole umbrellas. The airflow channel at the pressure relief window balances wind pressure, allowing air circulation between the inside and outside of the umbrella surface. This effectively counteracts the Bernoulli effect, enabling the umbrella to stably withstand winds of at least force 8 and reducing deformation damage to outdoor umbrellas. The rainproof eaves 3 compensate for the deficiencies of the pressure relief window opening, ensuring that sunshade, ventilation, and rain protection functions do not conflict. Furthermore, this patented umbrella fabric structure utilizes the traditional segmented processing technology, only adding the steps of opening the window and installing the rainproof eaves 3, without significantly altering the original process, resulting in lower production costs. Even if the umbrella fabric is damaged, it can be directly replaced. The overall manufacturing, storage, transportation, and installation costs are very low.

[0057] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.

[0058] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
