Description

Technical Field

[0001] The present application relates to the technical field of outdoor tents, and in particular to a tent expansion assembly and a combined tent. Background Art

[0002] Tents are portable shelters commonly used for camping and living in various outdoor activities. They are easy to assemble and disassemble, providing a comfortable resting space outdoors. The basic components of a tent include poles, a tarp, ground pegs, and guy ropes. Poles are typically made of fiberglass tubes or aluminum alloys, while tarps are typically made of rainproof materials such as nylon, canvas, and TC fabric. These materials are both strong and lightweight, ensuring they meet performance requirements for wind and rain protection while reducing the tent's weight.

[0003] Tents are generally placed directly in open-air environments, so the temperature inside the tent is greatly affected by environmental factors. For example, when setting up a tent in hot and humid weather, because the tent tarpaulin is made of nylon, canvas, TC cloth and other rainproof fabrics with average breathability, the air permeability inside the tent is poor. The air inside the tent cannot fully exchange and flow with the space outside the tent, making the tent like a "stew pot". The interior of the tent is stuffy and hot, and the comfort is very poor, which cannot meet the user's comfort requirements. If the user wants to improve the comfort of the tent's interior space, they need to open the tent tarpaulin to increase the connection between the interior of the tent and the external environment. However, after the user opens the tent tarpaulin, mosquitoes and insects outside will fly into the tent and bite the user, which also causes the comfort inside the tent to deteriorate. Summary of the Invention

DETAILED DESCRIPTION

[0031] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, the directions and positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.

[0033] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0034] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0035] Since tents are generally placed directly in an open-air environment, the fabrics of tent tarpaulins are mostly rainproof fabrics such as nylon, canvas, and TC cloth. However, the air permeability of nylon, canvas, and TC cloth layers of rainproof fabrics is relatively average. When users use the tent in hot and humid weather, the air permeability of the tent's interior space is very poor. The air inside the tent cannot exchange with the air flow outside the tent, causing the tent to become a stew pot. The interior space of the tent is stuffy and hot, and the comfort is very poor. If users want to improve the comfort of the tent's interior space, they can only open the tent tarpaulin to connect the interior space of the tent with the outside environment. However, after the tent tarpaulin is opened, mosquitoes in the external environment will fly into the interior space of the tent. The problem of poor air permeability of the tent interior space is solved, but the problem of mosquito bites arises again, making the combined tent very inconvenient to use.

[0036] Based on the above problems, refer to Figure 1-7 In the embodiment shown, the present application provides a tent expansion assembly and a combined tent, wherein the combined tent includes the tent expansion assembly, and thus the tent expansion assembly will not be described separately in the following description.

[0037] The combined tent includes a tent main body 100 and a tent expansion assembly 200. A connecting opening 120 is provided on the side wall of the tent main body 100. The tent expansion assembly 200 includes an expansion main body 210 and several connecting assemblies. The expansion main body 210 includes a breathable portion 220. The area of ​​the breathable portion 220 accounts for not less than 50% of the total area of ​​the expansion main body 210. The air permeability of the breathable portion 220 is better than the air permeability of other areas of the expansion main body 210. The connecting assembly is provided on the expansion main body 210. The connecting assembly is suitable for detachably connecting the expansion main body 210 to the tent main body 100, so that the expansion main body 210 and the tent main body 100 are enclosed to form an expansion space. The expansion main body 2100 is arranged opposite to the connecting opening 120, and then the expansion space is connected to the internal space of the tent main body 100 through the connecting opening 120. The air inside and outside the expansion space can flow out or flow into the expansion space through the breathable portion 220, so that the expansion space has good air permeability. During the use of the combined tent, the expansion space will not become stuffy, thereby improving the comfort of the expansion space.

[0038] Furthermore, the expansion body 210 includes a tarpaulin and a plurality of expansion poles 230. The expansion poles 230 are adapted to support the tarpaulin, thereby dividing the tarpaulin into a front tarpaulin 211 and side tarpaulins 212 located on either side of the front tarpaulin 211. Specifically, the front tarpaulin 211 has support holes with metal rings disposed therein. The top ends of the expansion poles 230 are adapted to be inserted into the metal rings, while the bottom ends of the expansion poles 230 are adapted to abut against the tent's erection surface, thereby providing support for the tarpaulin.

[0039] The ventilation portion 220 is arranged on the front tarpaulin 211 and the side tarpaulin 212. The area ratio of the ventilation portion 220 on the front tarpaulin 211 and the area ratio of the ventilation portion 220 on the side tarpaulin 212 are both not less than 60%. Preferably, the area ratio of the ventilation portion 220 on the front tarpaulin 211 and the area ratio of the ventilation portion 220 on the side tarpaulin 212 are 80% to 95%. The large-area ventilation portion 220 on the front tarpaulin 211 and the side tarpaulin 212 can ensure the air flow exchange between the expansion space and the external environment to the greatest extent, thereby avoiding stuffiness in the expansion space.

[0040] In most cases, the breathable portion 220 can be implemented as a breathable mesh, and the surface of the breathable mesh is provided with countless breathable holes. Air flow can flow into or out of the expansion space through the breathable holes, thereby improving the breathability of the expansion space. In addition, the aperture of the breathable holes is small, and mosquitoes in the external environment cannot pass through the breathable holes into the expansion space, thereby preventing users from being bitten by mosquitoes in the expansion space.

[0041] A first curtain 110 is also provided on the tent body 100. The first curtain 110 is provided on the same side as the communication opening 120. The first curtain 110 includes a main curtain 111 and a secondary curtain 112. The main curtain 111 and the secondary curtain 112 can be implemented as a whole piece of tarpaulin or as two pieces of tarpaulin spliced ​​together. The main curtain 111 is suitable for detachable connection with either the side tarpaulin 212 or the tent body 100. The secondary curtain 112 can be unfolded relative to the main curtain 111 to cover the air permeable portion 220 on the front tarpaulin 211 or folded relative to the main curtain 111 to be folded to one side of the main curtain 111. Specifically, when the expansion body 210 is connected to the tent body 100, the main curtain 111 is connected to the side curtain 212 and is arranged on the top of the front curtain 211 and the side curtain 212. The auxiliary curtain 112 is unfolded relative to the main curtain 111 and is located above the front curtain 211 to cover the air permeable portion 220 on the front curtain 211, and the projection of the front curtain 211 on the horizontal plane coincides with the projection of the auxiliary curtain 112 on the horizontal plane. Of course, the auxiliary curtain 112 can also be folded relative to the main curtain 111 and folded on one side of the main curtain 111; when the expansion body 210 is separated from the tent body 100, the auxiliary curtain 112 is folded relative to the main curtain 111 and folded on one side of the main curtain 111. The main curtain 111 is connected to the tent body 100. Preferably, when the auxiliary curtain 112 is folded relative to the main curtain 111, it is folded on the inner side of the main curtain 111.

[0042] It is worth mentioning that when the auxiliary screen 112 is unfolded relative to the main screen 111 to cover the ventilation portion 220 on the front tarpaulin 211, the auxiliary screen 112 can be supported and unfolded by components such as support rods and wind ropes to cast a shadow on the ventilation portion 220 of the front tarpaulin 211. At this time, the ventilation portion 220 on the front tarpaulin 211 is vertically shielded by the auxiliary screen 112. Due to changes in the angle of sunlight, the shadow of the auxiliary screen 112 on the front tarpaulin 211 will shift, and the horizontal projection of the front tarpaulin 211 and the horizontal projection of the auxiliary screen 112 will coincide, so that the auxiliary screen 112 can cover the ventilation portion 220 on the front tarpaulin 211 for as much time as possible; the auxiliary screen 112 can also naturally hang down on the front tarpaulin 211 to fit the front tarpaulin 211. At this time, the ventilation portion 220 on the front tarpaulin 211 is completely shielded by the auxiliary screen 112.

[0043] In some preferred embodiments, third connectors 130 are provided on the side and / or bottom edge of the auxiliary screen 112, and fourth connectors 180 are provided at corresponding positions on the main screen 111, which are detachably connected to the third connectors 130. Thus, the side and / or bottom edge of the auxiliary screen 112 are detachably connected to the inner side of the main screen 111. The third connectors 130 and the fourth connectors 180 can be implemented as connectors such as Velcro, zippers, and snap fasteners that cooperate with each other. These connectors are quick and easy to install and remove, and can quickly connect and separate the main screen 111 and the auxiliary screen 112.

[0044] The tent body 100 is further provided with a first connecting portion 140, which is arranged on the same side as the first curtain 110 and the communicating opening 120. The first connecting portion 140 can be implemented as a right-angled triangle-shaped tarpaulin. The long right-angled side of the first connecting portion 140 is fixedly connected to the tent body 100, and the hypotenuse of the first connecting portion 140 is suitable for detachably connecting with the main curtain 111 or the side tarpaulin 212. The side tarpaulin 212 includes a side connecting edge 213 and a top connecting edge 214. The connecting assembly includes a first connecting member 300 and a second connecting member 400 that are detachably connected to each other. The first connecting member 300 is arranged on the side connecting edge 213, and the second connecting member 400 is arranged on the top connecting edge 214. Correspondingly, the main curtain 111 is provided with a first connecting member 300, and the first connecting portion 1 A second connecting member 400 is provided on 40. When the expansion main body 210 is connected to the tent main body 100, the main curtain 111 is connected to the top connecting edge 214 of the side tarpaulin 212, and the side connecting edge 213 of the side tarpaulin 212 is connected to the first connecting part 140. At this time, the auxiliary curtain 112 can be folded on the inner side of the main curtain 111 through the cooperation of the third connecting member 130 and the fourth connecting member 180, or it can be unfolded relative to the main curtain 111 to cover the breathable part 220 on the front tarpaulin 211; when the expansion main body 210 is separated from the tent main body 100, the auxiliary curtain 112 is folded on the inner side of the main curtain 111 through the cooperation of the third connecting member 130 and the fourth connecting member 180, and the main curtain 111 is connected to the first connecting part 140 through the cooperation of the first connecting member 300 and the second connecting member 400. Similar to the third connector 130 and the fourth connector 180, the first connector 300 and the second connector 400 can be implemented as interoperable connectors such as hook-and-loop fasteners, zippers, and snap fasteners. Of course, the types of the first connector 300 and the second connector 400 can be different from those of the third connector 130 and the fourth connector 180. For example, the first connector 300 and the second connector 400 can be interoperable zippers, while the third connector 130 and the fourth connector 180 can be hook-and-loop fasteners or snap fasteners. It is worth noting that the placement of the first connector 300 and the fourth connector 180 on the main curtain 111 is not restricted and can be arranged side by side or staggered, as long as the coordination between the first connector 300 and the second connector 400 does not affect the coordination between the fourth connector 180 and the third connector 130.

[0045] In other embodiments, in addition to being connected to the tent body 100 through the first connecting portion 140, the main curtain 111 and the side tarpaulin 212 may also be directly connected to the tent body 100, that is, the second connecting member 400 is directly set on the side wall of the tent body 100. Then, when the expansion body 210 is connected to the tent body 100, the main curtain 111 is connected to the top connecting edge 214 of the side tarpaulin 212 through the cooperation of the first connecting member 300 and the second connecting member 400, and the side connecting edge 213 of the side tarpaulin 212 is connected to the tent body 100 through the cooperation of the first connecting member 300 and the second connecting member 400. When the expansion body 210 is separated from the tent body 100, the auxiliary curtain 112 is folded on the inner side of the main curtain 111 through the cooperation of the third connecting member 130 and the fourth connecting member 180, and the main curtain 111 is connected to the tent body 100 through the cooperation of the first connecting member 300 and the second connecting member 400.

[0046] Furthermore, the front tarpaulin 211 is rectangular, and the side tarpaulins 212 are parallelogram-shaped. When the expansion body 210 is connected to the tent body 100, the front tarpaulin 211 is tilted relative to the tent erection platform. The parallelogram-shaped side tarpaulins 212 allow the side connecting edges 213 to be tilted, allowing them to align with the oblique edges of the first connecting portion 140. Furthermore, the tent expansion assembly 200 utilizes the space created by the outward tilt of the front tarpaulin 211 to increase the size of the expansion space.

[0047] A shade curtain 240 is also provided on the side tarpaulin 212. The shade curtain 240 can be rolled up and folded or laid out flat. When the shade curtain 240 is rolled up and folded, the shade curtain 240 is suitable for revealing the breathable portion 220 on the side tarpaulin 212. When the shade curtain 240 is laid out flat, the shade curtain 240 is suitable for covering the breathable portion 220 on the side tarpaulin 212. Specifically, the top edge of the shade curtain 240 is fixedly connected to the side tarpaulin 212, and the bottom edge of the shade curtain 240 can be rolled up or folded relative to the top edge of the shade curtain 240 or laid flat downward. A fifth connector 241 is provided on the side and / or bottom edge of the shade curtain 240. The side and / or bottom edge of the shade curtain 240 can be detachably connected to the side tarpaulin 212 via the fifth connector 241. When the shade curtain 240 is laid flat, the side and / or bottom edge of the shade curtain 240 abuts against the side tarpaulin 212, completely shielding the air permeable portion 220 on the side tarpaulin 212, preventing rainwater from seeping into the air permeable portion 220 and preventing outsiders from observing the interior of the expanded space through the air permeable portion 220. The fifth connector 241 can be a zipper, Velcro, or other connector.

[0048] The blackout curtain 250 can also be used in conjunction with the auxiliary curtain 112 to meet the needs of users in different environments.

[0049] For example, when the sunlight is strong, the user can spread out the blackout curtain 240 to cover the air permeable portion 220 on the side tarpaulin 212, and use the supporting rods and wind ropes to support and unfold the auxiliary curtain 112 to shade the air permeable portion 220 on the front tarpaulin 211, thereby ensuring the air permeability of the expanded space while preventing direct sunlight from shining into the expanded space.

[0050] When sunlight is weak, the user can roll up and fold the blackout curtain 240 to reveal the ventilation portion 220 on the side tarpaulin 212, and fold the auxiliary tarpaulin 112 inside the main tarpaulin 111 to reveal the ventilation portion 220 on the front tarpaulin 211, so as to achieve optimal ventilation in the expanded space.

[0051] When the user wants a relatively private space, the user can spread out the blackout curtain 240 to cover the breathable portion 220 on the side tarpaulin 212, and let the auxiliary curtain 112 naturally hang down on the front tarpaulin 211 to cover the breathable portion 220 on the front tarpaulin 211. The breathable portions 220 on the front tarpaulin 211 and the side tarpaulin 212 are all covered, and outsiders cannot observe the situation in the expanded space through the breathable portion 220, so that the user can use it when resting at night.

[0052] In addition to being used to connect the expansion space 210 and the internal space of the tent main body 100, the connecting opening 120 can also be used as an opening for entering and exiting the internal space of the tent main body 100 when the tent expansion component 200 is separated from the tent main body 100 and the tent main body 100 is used alone. At this time, the auxiliary curtain 112 is unfolded relative to the main curtain 111, and the main curtain 111 and the auxiliary curtain 112 are supported and unfolded by components such as support rods and wind ropes. The main curtain 111 and the auxiliary curtain 112 after being supported and unfolded can cast a shadow on the connecting opening 120, thereby shading the connecting opening 120 from the sun and rain.

[0053] Of course, in some preferred embodiments, a first entrance and exit is opened along the height direction of the front tarpaulin 211 or between the front tarpaulin 211 and the side tarpaulin 212, and a closing connector 250 capable of opening or closing the first entrance and exit is provided at the edge of the first entrance and exit. The closing connector 250 can be a conventional connector such as a zipper or a snap button. Figure 1 In the illustrated embodiment, the closing connector 250 is implemented as a zipper, and the user can open or close the first entrance and exit by pulling the zipper. After the first entrance and exit is opened, the user can enter and exit the expansion space through the first entrance and exit.

[0054] In some embodiments, a second curtain 150 and a second entrance and exit 170 are further provided on the tent body 100. The second curtain 150 and the second entrance and exit 170 are arranged on the same side. The second curtain 150, the second entrance and exit 170, the first curtain 110, and the connecting opening 120 are on different side walls of the tent body 100. The top edge of the second curtain 150 is fixedly connected to the tent body 100 and is located above the second entrance and exit 170. The tent body 100 is provided with second connecting parts 160 that cooperate with the second curtain 150 on the left and right sides of the second entrance and exit 170. A first connecting member 300 is provided on the side of the second curtain 150, and a second connecting member 400 is provided on the second connecting part 160. Therefore, the side of the second curtain 150 can be detachably connected to the tent body 100 through the cooperation of the first connecting member 300 and the second connecting member 400 to open or close the second entrance and exit 170. When the second entrance and exit 170 is opened, the second curtain 150 is separated from the second connecting part 160, and the second curtain 150 can be supported and unfolded by components such as support rods and wind ropes.
