Description

Technical Field

[0001] The invention relates to a tent, and more particularly to a tent frame structure. Background Art

[0002] Although there are many shapes of existing outdoor tents, small tents usually adopt gable roofs and arc roofs. In particular, the existing gable roof cone tents generally use only two support rods to support the gable shape, and the tarpaulin is generally fixed to the ground by ground nails to form a polygon. Although the tent of this structure is easy to carry and has a small storage space, it is troublesome to install, and the space cannot be fully utilized. The user cannot stretch when turning around, sitting up, and moving in the tent, and will feel depressed and cramped when staying in the tent.

[0003] Therefore, some tents expand the space by increasing the number of support poles. After the multiple support poles are connected at the top, they spread outward and provide inclined support. However, such a structure will increase the overall weight of the tent and make it inconvenient to carry. Moreover, after the tent is unfolded, the space inside the tent will be divided and partitioned by the support poles, and the user's head will easily hit the support poles when standing in the tent. Summary of the invention

[0004] The object of the present invention is to provide a tent frame structure which has a large space and is convenient for users to move inside the tent.

[0005] To achieve the above object, the solution of the present invention is: A tent frame structure includes two main support poles intersecting and pivotally connected at the top, the two main support poles are unfolded to form a herringbone bracket, the lower end of each main support pole is pivotally connected to at least two extended support poles, the extended support poles extend outside the side of the main support pole and are supported on the ground.

[0006] Furthermore, the bottom surface surrounded by the supporting points at the bottom ends of all the extended support poles is a polygon with four or more sides. After the bottom surface is connected to the top of the main support pole through a flexible fabric, a cone-shaped tent that can stand independently is formed.

[0007] Furthermore, the lower ends of the two main support rods are respectively pivotally connected to two extended support rods, and the bottom surface formed by the supporting points on the ground supported by the bottom ends of the extended support rods and the bottom ends of the main support rods is a hexagon.

[0008] Furthermore, the extended support rod is pivotally connected to the main support rod through a connecting piece, the connecting piece is passed through the main support rod, at least two pivot grooves are provided on the peripheral side of the connecting piece, and the top end of the extended support rod is pivotally connected in the pivot groove.

[0009] Furthermore, the main support rod is a telescopic rod, which is positioned after being stretched, and a main support rod telescopic adjustment button for unlocking the stretched positioning of the main support rod is provided in the main support rod.

[0010] Furthermore, the extended support rod is a telescopic rod, the extended support rod is positioned after being stretched, and an extended support rod telescopic adjustment button for unlocking the stretched positioning of the extended support rod is provided in the extended support rod.

[0011] Furthermore, a top vertical rod extends upward from the pivotal joint at the top ends of the two main support rods.

[0012] Furthermore, the top ends of the two main support rods are pivotally connected to a top connecting piece, and the top vertical rod is connected to the top connecting piece and passes through upward.

[0013] Furthermore, the top vertical rod is movably arranged in the top connecting member and can be positioned after moving up and down. The top connecting member is provided with a top vertical rod telescopic adjustment button which can release the positioning of the top vertical rod.

[0014] After adopting the above scheme, the present invention can have at least the following advantages over the prior art: 1. By arranging an extended support rod at the lower end of the main support rod, the lower end of the tarpaulin matched with the tent frame of the present invention can be stretched out by the extended support rod, the space in the tent is expanded, and the user experience is improved.

[0015] 2. Extending the support pole can also provide a stable standing support for the main support pole, so that the entire tent can stand stably and independently, without the need for additional accessories such as ground nails, reducing the difficulty of assembling the tent.

[0016] 3. The extended support pole is smaller in size and length, and can be folded together with the main support pole, which does not affect the overall tent frame and is easy to carry.

[0017] 4. The extended support pole is located at the lower end of the main support pole. When it is unfolded and used, it will not divide the space inside the tent, and it also reduces the risk of the user's head hitting the support pole when standing in the tent.

DETAILED DESCRIPTION

[0020] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0021] like Figure 1 As shown, the present invention discloses a tent frame structure, which includes two main support poles 1 and a plurality of extended support poles 2. The two main support poles 1 intersect and pivot at the top. After the two main support poles 1 are unfolded, they are tilted and supported and connected at the top, that is, the two main support poles form a herringbone bracket after they are unfolded. At the same time, at least two extended support poles 2 are pivotally connected to the lower end of each main support pole 1, and the extended support poles 2 extend outside the side of the main support pole 1 and are supported on the ground.

[0022] After the extension support poles 2 are added, the bottom surface surrounded by the support points at the bottom of all the extension support poles 2 is a polygon with four or more sides. The bottom surface can be connected to the top of the main support pole 1 through a flexible cloth (tarpaulin) to form a cone-shaped tent that can stand independently. Adding an upper extension support pole 2 on the side of the main support pole 1 can increase the support surface outward, expand the use area of ​​the cone tent, and provide a stable standing support for the main support pole 1.

[0023] See also Figures 1 to 3 , which is the first embodiment of the present invention. In this embodiment, two extended support rods 2 are pivotally connected to the lower ends of the two main support rods 1, and the bottom surface formed by the supporting points of the bottom ends of the extended support rods 2 and the bottom ends of the main support rods 1 supported on the ground is a hexagon.

[0024] In the present embodiment, the bottom surface formed by the supporting points on the ground supported by the bottom ends of the extended support rods 2 and the bottom ends of the main support rods 1 is a hexagon. Therefore, when the tent frame structure of the present embodiment is covered with a tarpaulin (not shown in the figure), the tarpaulin will be supported between the bottom surface and the top end of the tent frame structure to form a complete conical tent with a polygonal bottom. This not only expands the space inside the tent but also enables the entire tent to stand stably and independently. There is no need to set up additional accessories such as ground nails, which reduces the difficulty of assembling the tent and improves the user experience.

[0025] The extended support pole 2 can be arranged at the lower end of the main support pole 1, and the extended support pole 2 can be connected to a position below the middle part of the main support pole 1. The overall volume and length of the extended support pole 2 are relatively small. When the main support pole 1 is folded, it can be folded at the side of the main support pole 1, and cooperate to achieve integrated folding, which will not cause much impact on the folded volume of the tent frame, is easy to carry, and will not divide the space inside the tent when unfolded for use, reducing the risk of the user's head hitting the support pole when standing in the tent.

[0026] See also Figure 4 In this embodiment, the extended support rod 2 is pivotally connected to the main support rod 1 through a connecting member 11, and the connecting member 11 can be inserted and fixed on the main support rod 1. Two pivot grooves 111 are provided around the connecting member 11, and the top end of the extended support rod 2 is pivotally connected in the pivot grooves 111. In other embodiments, the number of the pivot grooves 111 can be set according to the number of extended support rods 2 pivotally connected to the main support rod 1.

[0027] The main support rod 1 is a telescopic rod that can be positioned after being stretched. The main support rod 1 can be a telescopic sleeve structure with two or more sections to meet the support height of the main support rod 1 and can be folded into a small volume. In the telescopic sleeve, one section of the rod and the section of the rod adjacent to it and forming a sleeve connection can be matched by setting a positioning convex particle and a positioning hole (the end of the inner rod is convexly provided with an elastic convex particle, and the end of the outer rod is provided with a positioning hole. After the two are stretched relative to each other, the elastic convex particle bounces into the positioning hole, and the two rods are stretched and positioned). This is a prior art and will not be described in detail here. In this embodiment, the main support rod 1 is a three-section rod, and at the junction of the second section and the third section from top to bottom in the main support rod, a main support rod telescopic adjustment button 12 for unlocking the stretching and positioning of the main support rod 1 is provided to facilitate the telescopic adjustment of the main support rod 1 (convenient for folding). When the button is pressed (for example, by pressing the elastic convex particle to make it retract from the positioning hole), the positioning between the two sections of the rod is released, the telescopic adjustment is achieved, and the two lower sections of the main support rod 1 are retracted; conversely, the retracted rod is pulled outward until the two rods are restored to the locked position (the elastic convex particle protrudes upward into the positioning hole), that is, the length of the main support rod 1 is locked. In this embodiment, the main support rod telescopic adjustment button 12 is set on the connecting member 11, so that the structure of the main support rod 1 is more compact.

[0028] In this embodiment, the extension support rod 2 is a telescopic rod, specifically a two-section rod, and the extension support rod 2 is provided with an extension support rod telescopic adjustment button 21 for unlocking the extension support rod 2 to facilitate the telescopic adjustment (convenient folding) of the extension support rod 2. When the button is pressed, the extension support rod 2 can be released from the extension position, so that the extension support rod 2 can be retracted to a short length.

[0029] Thus, the main support pole 1 and the extension support pole 2 in this embodiment are both telescopic poles with variable lengths. When the tent needs to be folded, the main support pole 1 and the extension support pole 2 can be folded to the shortest length and then stored and carried, which can provide carrying convenience for the user.

[0030] See also Figure 5 In this embodiment, a top vertical rod 3 extends upward from the top pivoting point of the two main support rods 1, so as to increase the height of the top of the tent and increase the usable space in the tent. The top connecting member 31 in this embodiment forms a triangular connecting member, and the top ends of the two main support rods 1 are pivoted to the two sides of the top connecting member 31, and the top ends of the two main support rods 11 are connected to the top connecting member 31 to form a triangular support and can be retracted toward the middle. The top vertical rod 3 is inserted into the top connecting member 31 and passes upward, and a socket (not shown in the figure) with an opening upward can be formed on the top connecting member 31, and the top vertical rod 3 is inserted into the socket.

[0031] See also Figures 6 to 8 , which is the second embodiment of the present invention, the structure and connection relationship of the main support rod 1 and the extended support rod 2 are the same as those of the first embodiment. Fig. 9 The difference between the second embodiment and the first embodiment is that the top vertical rod 3 can be movably inserted into the top connecting member 31 and can be positioned after moving up and down. Furthermore, the top connecting member 3 is also provided with a top vertical rod telescopic adjustment button 311 that can release the top vertical rod 31 from its position, so that the top vertical rod 31 of the positioning support can be retracted to reduce the folding height. The top connecting member 31 in this embodiment is in the shape of a long strip. The pivot grooves on the left and right sides of the top connecting member 31 that open downward can be used to pivot the top ends of the two main support rods 1. A through hole (not shown in the figure) is provided in the middle of the top connecting member 31. The top vertical rod 3 is inserted into the through hole. A hollow plug column section 312 is also provided in the top connecting member 31 above the through hole. The top vertical rod 3 is movably inserted into the plug column section 312, i.e., the through hole. The top vertical rod telescopic adjustment button 311 is connected to the plug column section 312. A positioning hole may be provided in the column section 312, and an elastic convex particle (not shown in the figure) that can be popped out and positioned on the positioning hole may be provided at the bottom of the top vertical rod 3, and the top vertical rod telescopic adjustment button 311 can be pressed to press the elastic convex particle to retract into the positioning hole, so that the top vertical rod 3 is released from the positioning and can be retracted. With the above structure, the height of the top vertical rod 3 can be adjusted by the top vertical rod telescopic adjustment button 311, so that the height of the tent frame is flexible and the folding space can be saved when folding.

[0032] See also Fig.10, which is the third embodiment of the present case. The difference between it and the first and second embodiments mentioned above is that the extended support rods 2 in this embodiment are respectively pivoted at the bottom ends of the main support rods 1, and the main support rods 1 do not directly support the ground. The extended support rods 2 extending outward on both sides support the main support rods 1 at the same time. The bottom ends of the four extended support rods 2 are supported on the ground, and the supporting points form a quadrilateral.

[0033] The above is only an embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
