Description

Technical Field

[0001] The present application relates to the technical field of outdoor equipment, and particularly relates to an air column framework and an inflatable tent. Background Art

[0002] An inflatable tent is a type of tent. It designs a framework based on the principle of structural mechanics, and uses the characteristics of gas pressure to expand an airbag to form a column with a certain rigidity. Through organic combination, it props up the framework of the tent.

[0003] Most of the existing air column frameworks of inflatable tents have problems of complex structures and inconvenient inflation and deflation. The air column frameworks with complex structures mostly have multiple connection points. At the connection points, for example, there may be connecting components such as air pipes made of different materials from the air column framework. The setting of the connecting components not only increases the complexity of the structure of the air column framework, but also, at the connection points, there is a risk of the connecting components falling off. Moreover, the connecting components will also cause an increase in the overall weight of the inflatable tent. Summary of the Invention

[0027] Please refer to Figure 1 , the air column framework 1 of the embodiment of the present application is used to support the tent cloth after inflation, so that the tent is formed.

[0028] The air column framework 1 of this embodiment includes an annular air column 11 and a plurality of leg air columns 12. The air column framework 1 can be made of, for example, a PVC-coated polyester interwoven fabric material. Here, both the annular air column 11 and the leg air columns 12 form columns after being inflated and are flat bags when not inflated. The annular air column 11 and the leg air columns 12 are just names for two components of the air column framework 1 and do not mean that these two components always maintain a columnar shape.

[0029] The annular air column 11 is used to support the tent fabric to form the tent top, and the plurality of leg air columns 12 are used to support the tent fabric to form the accommodation space of the tent; the plurality of leg air columns 12 are evenly distributed along the circumferential direction of the annular air column 11, and one end of each leg air column 12 is respectively communicated with the annular air column 11, and the other end of each leg air column 12 is a closed end; the annular air column 11 and the plurality of leg air columns 12 are integrally formed.

[0030] Specifically, in this embodiment, the annular air column 11 can be, for example, a circular annular air column 11 or a polygonal annular air column 11. As Figure 2 shown, if the annular air column 11 is a polygonal annular air column 11, the number of sides of the polygonal annular air column 11 is equal to the number of leg air columns 12. The polygonal annular air column 11 only needs to ensure that the outer edge contour is a regular polygon, and there is no requirement for the inner hole contour, which can also be a regular polygon or other shapes such as a circle. One leg air column 12 is respectively connected to each vertex of the outer contour of the polygonal annular air column 11.

[0031] As Figure 1As shown, in this embodiment, it is required that the number of the leg air columns 12 is not less than five, for example, it can be six. The more the number, the larger the internal space after the inflatable tent is set up, and it is easier to ensure the stability and reliability of the support structure of the whole inflatable tent. The multiple leg air columns 12 in this embodiment are relatively independently arranged. Only one end of each leg air column 12 is connected to the annular air column 11, and no connecting components are provided between the leg air columns 12 in other parts. The fixation of the leg air columns 12 depends on the combined action of the annular air column 11 and the tent cloth. That is, in addition to the annular air column 11 at the top and the leg air columns 12 arranged around the annular air column 11, the air column framework 1 in this embodiment has no any other components, greatly simplifying the structure and weight of the air column framework 1, and the fewer components of the air column framework 1 are also more convenient for inflating and deflating it, making the setup, disassembly and storage of the inflatable tent faster. The leg air column 12 in this embodiment includes a first support portion 121 and a second support portion 122 which are connected. The included angle between the first support portion 121 and the second support portion 122 is an obtuse angle. One end of the first support portion 121 is communicated with the annular air column 11, and the other end is communicated with the second support portion 122. The first support portion 121 and the annular air column 11 are jointly used to support the tent cloth to form the tent top. The second support portion 122 is used to be perpendicular to the bottom surface of the tent cloth to form the columns of the inflatable tent. The first support portion 121 extends from the top of the second support portion 122 to be connected with the annular air column 11 to form the top of the inflatable tent. The top of the inflatable tent is approximately in an umbrella shape after being set up. A charging and discharging device 2 is provided at the lower part of the second support portion 122 of one of the leg air columns 12, and a pressure relief valve 3 is provided at the same height of the second support portion 122 of another adjacent leg air column 12. The charging and discharging device 2 can include, for example, an inflation port with a one-way valve, an air outlet with a one-way valve, or can also include an air pump. The air pump is used to inflate or exhaust the air column framework 1. When inflating the air column framework 1, the air outlet of the air pump is communicated with the inflation port, and when exhausting the air column framework 1, the air inlet of the air pump is communicated with the air outlet. The pressure relief valve 3 is used to prevent the air column framework 1 from being damaged due to excessive air pressure during inflation. When the air pressure in the air column framework 1 reaches the preset value, the pressure relief valve 3 can automatically relieve the pressure of the air column framework 1.

[0032] An embodiment of the present application further provides an inflatable tent, which includes a tent cloth and the air column framework 1 in the above embodiment. After the air column framework 1 is inflated, it is used to support the tent cloth to make the tent take shape.

[0033] The tent cloth can be made of materials such as Oxford cloth or PVC-coated cloth. Specifically, as Figure 3 shown, the tent cloth includes side tent cloths and a bottom tent cloth (not shown) connected to the side tent cloths. The side tent cloths are used to form the conical top and side walls of the tent, and the bottom tent cloth is used to form the bottom surface of the tent. As Figure 3 and Figure 4As shown, the side awning is composed of a plurality of side cloth units 4 connected in sequence along the circumference of the tent. The number of side cloth units 4 is equal to the number of leg air columns 12. An air column threading pocket 5 is provided at the connection of every two adjacent side cloth units 4. The air column threading pocket 5 is arranged on the inner surface of the side awning for threading the leg air column 12. Both ends of the air column threading pocket 5 are open, and an opening and closing member 51 is provided through the air column threading pocket 5 along the length direction. That is, after the inflatable tent is set up, the cross-section formed by the plurality of side cloth units 4 is a regular polygon shape, and the second support portions 122 of the plurality of leg air columns 12 are located at the vertices of the regular polygon. When the inflatable tent is set up, the position of the leg air column 12 is restricted by the tent cloth, so that the relative position of the air column framework 1 and the tent cloth is fixed. The air column threading belt can be composed of two pieces of cloth. One end of the two pieces of cloth in the width direction is fixedly connected to the tent cloth, and the other end in the width direction is provided with an opening and closing member 51. The opening and closing member 51 is used to connect the two pieces of cloth to form a receiving space for receiving the leg air column 12. The opening and closing member 51 can be, for example, a zipper, a magic tape, a hook or a connecting rope, or any other component that is convenient for connection. After the leg air column 12 is threaded through the air column threading belt, the air column framework 1 is inflated, and then the air column framework 1 can firmly support the tent cloth.

[0034] To make the connection between the air column framework 1 and the tent cloth more firm and reliable, a connection structure (not shown) can also be provided at the bottom of the second support portion 122 of the leg air column 12. The connection structure is used for detachable connection with the bottom awning. The connection structure can be, for example, a magic tape, a snap button or a zipper.

[0035] To facilitate the use of the tent at night, one or more reflective strips (not shown) can also be provided on the outer surface of the side awning to facilitate finding or locating the tent in a dark environment.

[0036] The air column framework and the inflatable tent provided by the embodiments of the present application have a simple overall structure of the air column framework, are easy to inflate and deflate, and have a stable and reliable framework structure. The inflatable tent is easy to set up, disassemble and store, reduces the overall weight of the inflatable tent, and expands the internal accommodation space of the inflatable tent.
