Abstract
Description
Technical Field
[0001] This utility model relates to the field of sunshade technology, and in particular to a windproof sunshade. Background Technology
[0002] In strong winds, the lower surface of a sun umbrella is subjected to significant airflow force due to the wind, causing the entire umbrella to tilt or be blown away, easily leading to damage to the umbrella and injury to people under it. Therefore, how to make sun umbrellas allow airflow to pass through easily in strong winds is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0003] The purpose of this invention is to provide a windproof sunshade that allows airflow to pass through easily in strong winds.
[0004] To achieve the above objectives, this utility model provides the following solution:
[0005] This utility model discloses a windproof sunshade umbrella, including an umbrella canopy, umbrella ribs and umbrella posts. The umbrella ribs include a support rod for supporting the lower surface of the umbrella canopy, and also include an elastic rod.
[0006] The support rod has a separable section that can be separated from the umbrella canopy, the separable section extending from one end away from the umbrella post toward one end closer to the umbrella post;
[0007] The end of the elastic rod near the umbrella column is connected to the support rod or the umbrella column, and the end of the elastic rod away from the umbrella column is connected to the umbrella canopy, so that the elastic force of the elastic rod presses the umbrella canopy against the separable section.
[0008] Preferably, the windproof sunshade umbrella further includes a limiting sleeve, which is connected to the lower surface of the umbrella surface, and the elastic rod passes through the limiting sleeve.
[0009] Preferably, the elastic rod is magnetically attracted to the separable segment.
[0010] Preferably, the separable section is fixed with a magnet; the elastic rod itself is made of ferromagnetic material, and / or the elastic rod is connected to an adsorption element made of ferromagnetic material.
[0011] Preferably, the magnet is embedded in the mounting base, and the mounting base is connected to the separable section.
[0012] Preferably, the mounting base has a first section with a relatively large cross-sectional area and a second section with a relatively small cross-sectional area; the magnet is embedded in the first section, and the second section is inserted into the end of the support rod opposite to the umbrella column.
[0013] Preferably, there is a stepped surface between the first section and the second section, and the stepped surface is in contact with and positioned with the end face of the support rod.
[0014] Preferably, the adsorption element is located directly above the first section.
[0015] Preferably, the elastic rod is located directly above the support rod, and the suction element is located at the end of the elastic rod opposite to the umbrella column.
[0016] Preferably, the umbrella canopy includes multiple annular umbrella layers, with adjacent annular umbrella layers separated by a support member to form a wind gap, and the upper and lower ends of the support member being connected to the two adjacent annular umbrella layers respectively; the end of the elastic rod facing away from the umbrella column is connected to the lowest annular umbrella layer.
[0017] This utility model achieves the following technical advantages compared to related technologies:
[0018] The detachable section of the support pole is not connected to the canopy, so it can only support the canopy and cannot prevent it from moving upwards. When the wind is strong, the edge of the canopy flips up, causing the detachable section of the support pole to separate from the canopy, and the elastic rod bends elastically. At this time, the canopy reduces its windward area by folding itself, thereby reducing the thrust of the airflow on the canopy and achieving a windproof effect.
[0019] As the wind decreases, the elastic rod gradually returns to its original state under its own elastic force. The end of the elastic rod away from the umbrella column pulls the umbrella surface closer to the support rod, causing the umbrella surface to gradually return from a folded state to an unfolded state.
[0020] Therefore, this invention does not completely fix the umbrella canopy to the support pole, but instead makes the support pole have a detachable section to allow the edge of the umbrella canopy to flip up, achieving a windproof effect when the ambient wind force is strong. At the same time, the elastic rod provides elasticity to restore the umbrella canopy, allowing it to quickly recover when the wind force decreases.
[0021] In a preferred embodiment of this invention, the elastic rod and the separable section are magnetically adsorbed. Magnetic adsorption increases the difficulty of bending and deforming the elastic rod, ensuring that the umbrella surface only folds when the wind is strong and not when the wind is weak, thus providing better sunshade and rain protection. Magnetic adsorption also improves the return speed of the elastic rod, allowing it to quickly and accurately return to its initial position after the wind decreases.
[0022] In a preferred embodiment of this invention, the air gap between two adjacent annular umbrella layers allows airflow to flow out radially along the umbrella column, thereby reducing the resistance of the umbrella surface to the airflow. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] The purpose of this invention is to provide a windproof sunshade that allows airflow to pass through easily in strong winds.
[0031] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The connection referred to in this embodiment refers to a fixed connection, including detachable fixed connections (e.g., connections using fasteners such as bolts and nuts) and non-detachable fixed connections (e.g., welding, or bonding with adhesive).
[0032] Reference Figures 1-4 This embodiment provides a windproof sunshade umbrella, including an umbrella canopy 1, umbrella ribs, and umbrella posts. The umbrella ribs include support rods for supporting the lower surface of the umbrella canopy 1. The windproof sunshade umbrella also includes an elastic rod 2.
[0033] The support of the support pole to the umbrella canopy 1 can be direct contact support or indirect support by setting an intermediate component between the two. The cross-sectional shape of the elastic rod 2 can be flexibly selected, such as square, circular, U-shaped or other shapes.
[0034] The strut has a separable section that can be separated from the canopy 1, the separable section extending from one end away from the canopy post to the other end closer to the canopy post.
[0035] The end of the elastic rod 2 near the umbrella column is connected to the support rod or umbrella column, and the end of the elastic rod 2 away from the umbrella column is connected to the umbrella canopy 1, so that the elastic force of the elastic rod 2 presses the umbrella canopy 1 towards the separable section. The connection method of the end of the elastic rod 2 can be flexibly selected, such as fixing by U-shaped buckles, fixing by screws, fixing by sleeves, fixing by binding and other common fixing methods.
[0036] The principle of this windproof and sunshade umbrella is as follows:
[0037] There are no special restrictions on the structure of the umbrella ribs and the connection method between the umbrella ribs and the umbrella column. Any structure known to those skilled in the art can be used, such as the structure of the umbrella ribs and the connection method between the umbrella ribs and the umbrella column corresponding to the Roman umbrella.
[0038] The detachable section of the support rod is not connected to the canopy 1, so it can only support the canopy 1 and cannot prevent it from moving upwards. When the wind is strong, the edge of the canopy 1 flips up, causing the detachable section of the support rod to separate from the canopy 1, and the elastic rod 2 bends elastically. At this time, the canopy 1 reduces its windward area by folding itself, thereby reducing the thrust of the airflow on the canopy 1 and achieving a windproof effect.
[0039] As the wind decreases, the elastic rod 2 gradually recovers under its own elastic force. The end of the elastic rod 2 away from the umbrella column pulls the umbrella surface 1 closer to the support rod, so that the umbrella surface 1 gradually recovers from the folded state to the unfolded state.
[0040] Therefore, in this embodiment, the umbrella canopy 1 is not completely fixed to the support pole. Instead, the support pole has a separable section to allow the edge of the umbrella canopy 1 to flip up, achieving a windproof effect when the ambient wind force is strong. At the same time, the elastic rod 2 provides elasticity to restore the umbrella canopy 1, allowing it to quickly recover when the wind force decreases.
[0041] In some examples, the umbrella column is hollow to reduce overall weight. The umbrella column is telescopic, allowing adjustment of the height of the canopy 1 by changing the length of the column.
[0042] In some examples, the windproof sunshade also includes a retaining sleeve connected to the lower surface of the canopy 1, through which the elastic rod 2 passes.
[0043] The limiting sleeve can be a strip of fabric with a U-shaped or O-shaped cross-section, sewn and fixed to the umbrella surface 1 to provide a channel for the elastic rod 2 to pass through. Therefore, the elastic rod 2 can pull the umbrella surface 1 not only at the end away from the umbrella column, but also at the position of the limiting sleeve.
[0044] When the channel provided by the limiting sleeve is long, it can provide a better covering effect for the elastic rod 2, preventing the elastic rod 2 from piercing the user when it is bent or accidentally broken.
[0045] The limiting sleeve can also be a sleeve, a U-shaped buckle, or other structures, as long as it can provide a channel for the elastic rod 2 to pass through so as to bind the elastic rod 2 to the umbrella surface 1.
[0046] The limiting sleeve can also be two cloth strips with their upper ends connected to the umbrella surface 1. After the lower ends of the two cloth strips are tied together, they form a U-shaped structure through which the elastic rod 2 passes.
[0047] In some examples, the elastic rod 2 is magnetically attached to the separable section. Magnetic attachment increases the difficulty of bending and deforming the elastic rod 2, ensuring that the umbrella canopy 1 only folds when the ambient wind is strong, and does not fold when the ambient wind is weak (e.g., below level three), thus providing better sunshade and rain protection. Magnetic attachment also improves the reset speed of the elastic rod 2, allowing it to quickly and accurately return to its initial position after the wind weakens.
[0048] The magnetic adsorption here can be the adsorption between magnets or the adsorption between a magnet and a ferromagnetic material.
[0049] In some examples, the separable segment is fixed with a magnet. The elastic rod 2 itself is made of ferromagnetic material, and / or, the elastic rod 2 is connected to an adsorption element made of ferromagnetic material.
[0050] When the elastic rod 2 itself is made of magnetic material, its magnetic strength can be controlled by adding ferromagnetic substances. The shape of the adsorption element is preferably a thin sheet, with a thickness generally not exceeding 3 mm, to reduce the overall weight. The adsorption element can be an iron sheet.
[0051] In some examples, the magnet is embedded in the mounting base 3, which is connected to the separable segment.
[0052] Mounting base 3 is preferably made of plastic to reduce overall weight. The recessed mounting method exposes part of the magnet's surface, reducing the weakening of the magnet's magnetic field by mounting base 3.
[0053] In some examples, the mounting base 3 has a first section 31 with a relatively large cross-sectional area and a second section 32 with a relatively small cross-sectional area. A magnet is embedded in the first section 31, and the second section 32 is inserted into the end of the support rod away from the umbrella column.
[0054] The strut is typically made of alloy profile with a hole at its end. The second section 32 is inserted into the hole at the end of the strut to position the mounting base 3. After the second section 32 is inserted into the end of the strut, bolts can be screwed into the strut to tighten the second section 32, improving the fixing effect of the mounting base 3.
[0055] The cross-sectional area of the first section 31 is larger than that of the second section 32, which is used to provide a larger positioning contact surface to contact the adsorption component and prevent the first section 31 from being misaligned with the adsorption component when the elastic rod 2 is reset.
[0056] In some examples, there is a stepped surface 33 between the first segment 31 and the second segment 32, which is positioned in contact with the end face of the strut.
[0057] In some examples, when the edge of the umbrella 1 does not fold upward under the action of wind, the adsorption element is located directly above the first section 31, and the upper surface of the first section 31 is provided with a positioning groove 34 for positioning the adsorption element.
[0058] In some examples, when the edge of the umbrella canopy 1 does not fold upward under the action of wind, the elastic rod 2 is located directly above the support rod, and the suction element is located at the end of the elastic rod 2 away from the umbrella column.
[0059] The number of elastic rods 2 is preferably the same as the number of support rods. For commonly used parasols such as Roman umbrellas, multiple support rods are generally distributed radially around the umbrella pole. The elastic rods 2 are located directly above the support rods, so the multiple elastic rods 2 are also distributed radially.
[0060] As the number of elastic rods 2 increases, the portion of the edge area of the umbrella surface 1 that can be folded upwards increases, thereby minimizing the windward area under strong winds and adapting to winds from different directions.
[0061] In some examples, the canopy 1 includes multiple annular canopy layers 11, with adjacent annular canopy layers 11 separated by a support member 12 to form a wind gap 13. The upper and lower ends of the support member 12 are respectively connected to the two adjacent annular canopy layers 11. The end of the elastic rod 2 facing away from the canopy column is connected to the lowest annular canopy layer 11.
[0062] The lowest annular umbrella layer 11 reduces its windward area by folding upwards. The air gap 13 between two adjacent annular umbrella layers 11 allows airflow to flow out radially along the umbrella column, thereby reducing the resistance of the umbrella surface 1 to the airflow.
[0063] To improve the sunshade and rain protection effect, for two adjacent annular umbrella layers 11, in the top view direction, the outer contour of the upper annular umbrella layer 11 is overlaid on the inner contour of the lower annular umbrella layer 11, that is, the two adjacent annular umbrella layers 11 have annular overlapping area in the top view direction.
[0064] In order to reduce the overall volume, for two adjacent annular umbrella layers 11, in the top view direction, the outer contour of the upper annular umbrella layer 11 is inside the outer contour of the lower annular umbrella layer 11, and the inner contour of the upper annular umbrella layer 11 is inside the inner contour of the lower annular umbrella layer 11.
[0065] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
