Abstract
Description
[0001] The invention belongs to the technical field of parasols and relates specifically to the umbrella structure of an outdoor parasol.
[0002] Parasols are ubiquitous in people's daily lives, serving as protection from the sun or rain and being essential equipment for leisure activities at home or while camping. They can provide welcome shade on hot summer days, which is why they are commonly found in outdoor cafes, rest areas, meadows, parks, and along the coast.
[0003] This type of canopy is larger than that of ordinary umbrellas. The diameter of the canopy is generally larger, and the volume of the canopy body is also relatively large. It can provide a large area for sun protection, so the frame, which provides structural support for the canopy, must be sufficiently long. The frame of a conventional parasol is fixed, so the overall length after use is at least equal to the length of the frame, and the space required is relatively large. This is especially true if the canopy area is 3 m². 2 If the folded length exceeds 1.5 m, it is usually greater than 1.5 m. 2 This leads to relatively cumbersome storage, which is not conducive to transport by car. Furthermore, the packaging and transport operations also require a larger packaging volume, resulting in higher packaging and transport costs.
[0004] The object of the invention is to provide an umbrella structure that is reasonable and simple in structure, easy to fold and store, reduces volume and lowers transport costs.
[0005] The present invention aims to achieve the following: A canopy surface structure of an outdoor parasol comprising an upper canopy section, a lower canopy section, a frame, and a support pole, wherein one end of the frame is rotatably attached to the upper canopy section, wherein one end of the support pole is rotatably attached to the lower canopy section, and wherein the other end of the support pole is rotatably connected to the central end of the frame, wherein the canopy surface can be controlled to fold or open by driving the lower canopy section away from or near the upper canopy section by external force, wherein the cross-section of the frame is an oval structure and comprises a long frame, a short frame, and an elastic connecting device, wherein the long frame and the short frame are each hollow structures, and wherein one end of the short frame has a shrinkable section that extends conveniently into the long frame.wherein the short umbrella frame is always connected to the long umbrella frame by the elastic connecting device, wherein the elastic connecting device comprises a support torsion spring and an elastic rope, wherein the long umbrella frame and the short umbrella frame are provided with a support torsion spring, wherein both ends of the elastic rope are connected to the support torsion spring in the long umbrella frame and the short umbrella frame, respectively.
[0006] In the umbrella structure of the outdoor parasol described above, the support torsion spring comprises two support columns and an elastic ring, with each of the two support columns being connected to the elastic ring, and the two support columns being inclined towards each other.
[0007] In the umbrella structure of the outdoor parasol described above, the ends of the two support columns always lie against the inner wall of the long umbrella frame and the inner wall of the short umbrella frame under the elastic effect of the elastic ring.
[0008] In the umbrella structure of the outdoor parasol described above, plugs are provided at both ends of the umbrella frame and the support pole.
[0009] In the umbrella structure of the outdoor parasol described above, the shrinking part of the short umbrella frame has a play adjustment with the inner wall of the long umbrella frame.
[0010] In the umbrella structure of the outdoor parasol described above, the ratio of the length of the short umbrella frame to the length of the long umbrella frame is 1:2.
[0011] In the umbrella structure of the outdoor parasol described above, the length of the shrinking part of the short umbrella frame is between 1 / 9 and 1 / 10 of the length of the short umbrella frame.
[0012] The outstanding and advantageous technical effects of this invention compared to the prior art are:
[0013] The umbrella frame of the umbrella surface structure of the invention consists of a long umbrella frame and a short umbrella frame. The long and short umbrella frames are connected by an elastic connecting device, and one end of the short umbrella frame is provided with a shrinkable section that can be inserted into the long umbrella frame. When it needs to be folded, the shrinkable section of the short umbrella frame is simply pulled out of the long umbrella frame, which shortens the length of the umbrella frame, facilitates transport, and reduces transport costs. Fig. Figure 1 is a schematic representation of the structure of the invention. Fig. Figure 2 is a cross-sectional view of the umbrella frame of the invention. Fig. Figure 3 is a schematic representation of the structure of the upper canopy part, the lower canopy part, the canopy frame and the support pole of the invention. Fig. Figure 4 is an enlarged view at A of the invention. Fig. Figure 5 is a structural schematic representation of the short umbrella frame of the invention.
