This application claims priority to and the benefit of the patent application titled “A windproof foldable canopy tent”, application number 2023201493852, filed in the China National Intellectual Property Administration on Feb. 8, 2023. The specification of the above-referenced patent application is incorporated herein by reference in its entirety.
The present invention, in general, relates to outdoor articles, and in particular, relates to a windproof foldable canopy tent.
Double-ceiling foldable canopy tents comprise two ceilings, that is, an upper ceiling and a lower ceiling. The area of the upper ceiling is usually smaller than the area of the lower ceiling. A sunroof is reserved at corresponding positions of the lower ceiling and the upper ceiling, so that a ventilation channel is formed between the two ceilings for better ventilation in the foldable canopy tent. However, in a conventional double-ceiling foldable canopy tent, the ventilation channel is fixed and cannot be adjusted according to a wind force. When the wind force is too strong, wind resistance is substantially high, causing instability of the foldable canopy tent.
To overcome the above-recited problem in a conventional foldable canopy tent, the present invention provides a windproof foldable canopy tent.
The windproof foldable canopy tent comprises a tent frame assembly, a ceiling assembly, an upper tarpaulin, and a lower tarpaulin. The ceiling assembly is arranged on the tent frame assembly. The ceiling assembly comprises a tent top plate, multiple foldable arm mechanisms annularly distributed about a periphery of the tent top plate, and multiple elastic supporting rods correspondingly arranged on the foldable arm mechanisms. A distal end of each of the foldable arm mechanisms, away from the tent top plate, is mounted to the tent frame assembly. The upper tarpaulin and the lower tarpaulin are disposed on the ceiling assembly. The lower tarpaulin is supported and connected to the foldable arm mechanisms. The upper tarpaulin is supported and connected to the elastic supporting rods. The elastic supporting rods are configured to tension the upper tarpaulin firmly. When a wind force is substantially larger than the tensioning force, the elastic supporting rods bend and warp to enlarge a ventilation channel defined between the upper tarpaulin and the lower tarpaulin.
In an embodiment, the elastic supporting rods are made of glass fiber or carbon fiber.
In an embodiment, a distal end of each of the elastic supporting rods, away from the tent top plate, is connected to a corner of the upper tarpaulin.
In an embodiment, each of the foldable arm mechanisms comprises a tent top rod rotatably connected to the tent top plate. Each of the elastic supporting rods is arranged on the tent top rod of a corresponding one of the foldable arm mechanisms.
In an embodiment, the tent top rod is mounted to a corresponding one of the elastic supporting rods using a fixing bracket.
In an embodiment, the fixing bracket comprises a tent rod fixing hole and an elastic rod fixing hole. The tent rod fixing hole is connected to the tent top rod. The elastic rod fixing hole is connected to the corresponding one of the elastic supporting rods.
In an embodiment, each of the foldable arm mechanisms further comprises a tent frame rod and an auxiliary rod. A first end of the tent frame rod is rotatably connected to the tent top rod, and a second end of the tent frame rod is rotatably connected to an upper end of a supporting leg of the tent frame assembly. A first end of the auxiliary rod is rotatably connected to the tent frame rod, and a second end of the auxiliary rod is rotatably connected to a sliding sleeve. The sliding sleeve is mounted on the supporting leg of the tent frame assembly to slide up and down the supporting leg.
In an embodiment, the number of the foldable arm mechanisms and the elastic supporting rods is both four. In an embodiment, projections of the upper tarpaulin and the lower tarpaulin on a horizontal plane are both rectangular.
In the present invention, the elastic supporting rods are used for mounting and tensioning the upper tarpaulin. Under normal conditions, the elastic supporting rods press the upper tarpaulin tightly. When the wind force is larger than the tensioning force, the elastic supporting rods bend and warp to open the upper tarpaulin, thereby forming a ventilation channel, which reduces wind resistance and increases the stability of the foldable canopy tent. In addition, the elastic supporting rods tension the upper tarpaulin and prevent the upper tarpaulin from ponding.

In the description of the present invention, it is understood that the terms “one end”, “the other end”, “upper”, “horizontal”, “center”, “end”, etc., relating to an orientation or a positional relationship are in line with the orientations or the positional relationships shown in the drawings. Such terms are used herein merely to provide an easy or simplified description of the present invention, rather than indicating or implying that a device or an element must have a specific orientation, or be constructed and operated in a specific orientation, and shall not be understood as a limitation of the present invention.
The present invention is further described with the attached drawings as follows.
Disclosed herein is a windproof foldable canopy tent 100 comprising a tent frame assembly 1, a ceiling assembly 2, a lower tarpaulin 5, and an upper tarpaulin 3 as shown in -shaped structure, with a sunroof opened in the middle. The lower tarpaulin 5 is supported and connected to the four middle foldable arm mechanisms 20. In an embodiment, a projection of the upper tarpaulin 3 on a horizontal plane is a square. In another embodiment, the projections of the upper tarpaulin 3 and the lower tarpaulin 5 on a horizontal plane are rectangular. The upper tarpaulin 3 is supported and connected to the four elastic supporting rods 21. The elastic supporting rods 21 are configured to tension the upper tarpaulin 3 firmly. When a wind force is substantially larger than the tensioning force, the elastic supporting rods 21 bend and warp to enlarge a ventilation channel 4 defined between the upper tarpaulin 3 and the lower tarpaulin 5 shown in
When the elastic supporting rods 21 are not upwarping, the size of the ventilation channel 4 depends on a proximity between the upper tarpaulin 3 and the lower tarpaulin 5. When the upper tarpaulin 3 abuts against the lower tarpaulin 5 tightly, the ventilation channel 4 is almost closed. The proximity between the upper tarpaulin 3 and the lower tarpaulin 5 can be adjusted as required.
The center 3a of the upper tarpaulin 3 shown in
In an embodiment, each of the elastic supporting rods 21 is a glass fiber rod. In another embodiment, each of the elastic supporting rods 21 is a carbon fiber rod or another elastic rod.
In the present invention, the elastic supporting rods 21 are used for mounting and tensioning the upper tarpaulin 3. Under normal conditions, the elastic supporting rods 21 press the upper tarpaulin 3 tightly. When the wind force is larger than the tensioning force, the elastic supporting rods 21 bend and warp to open the upper tarpaulin 3, thereby forming the ventilation channel 4, which reduces wind resistance and increases the stability of the foldable canopy tent 100. In addition, the elastic supporting rods 21 tension the upper tarpaulin 3 and prevent the upper tarpaulin 3 from ponding.
The windproof foldable canopy tent 100 in an extended state and a folded state without the upper tarpaulin 3 and the lower tarpaulin 5 is shown in
As shown in
It should be understood that the number and the distribution of the supporting legs 11 in the tent frame assembly 1 of the windproof foldable canopy tent 100 can be adjusted as required; accordingly, the number and the distribution of the lateral foldable arm mechanisms 13, the middle foldable arm mechanisms 20, and the elastic supporting rods 21 as well as the shape of the upper tarpaulin 3 and the lower tarpaulin 5 can be adjusted as required.
It shall be noted that the above embodiments have been provided only for illustrating the technical scheme of the present invention and not to limit the present invention. Although the present invention has been detailed with reference to the above embodiments, those ordinarily skilled in the art should understand that they can still modify the technical scheme recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; however, such modifications or replacements do not separate the essence of technical schemes from the substance and scope of the technical scheme provided by the embodiments of the present invention.
