Description

Technical Field

[0001] The utility model relates to outdoor leisure products, and more specifically to a tent frame. Background Art

[0002] As an outdoor product, tents have become a must-have for many people who like to travel, camp, feel the nature and other outdoor leisure activities. At present, tents used for outdoor leisure are diverse in form, including large and small, square and round. The tent is mainly composed of tent cloth and a tent frame for supporting the tent cloth. The tent frame is generally composed of multiple groups of support rods connected to the top rod. The support rod group supports the top rod, and the top rod forms the top support.

[0003] In order to increase the top surface and usable area of ​​the tent, a common tent top is provided with a pivot seat to connect multiple tent top poles, and each top pole is connected to the vertical pole through a connector. Such a tent pole is large in size and weight, and the pivot seat and connector will also increase the cost. In order to make the tent simpler and lighter, there are also one-shaped top tents on the market that use only a cross bar as a top pole, and then add struts at both ends of the top cross bar to form an I-shaped support. Although this structure increases the tent top, the open part of the tent top surface is mainly supported by the struts at both ends. If there is no support in the middle, it will be relatively weak and prone to depression, and it will also compress the top space of the tent. In addition, for the one-shaped top tent, it is common that the two ends of the top pole are connected to two or more struts through a connector, and a plurality of pivot slots for connecting the top pole and the struts are provided on the connector, which increases the cost of components and installation. In addition, the rod forms a torsion structure in the connector, which will also affect the wind resistance of the tent. Utility Model Content

[0040] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0041] Combination Figure 1 or Figure 3As shown, the utility model discloses a tent frame, including at least one set of pole groups, the pole group includes a support assembly and a ceiling assembly, the tent frame can be supported by only a single set of pole groups, after the pole group is assembled, unfolded and connected (such as covered) with a tarpaulin (not shown in the figure), a simple tent can be formed, while the pole group supports the tarpaulin, the unfolded and stretched tarpaulin also has a limiting and shaping effect on the unfolded pole group. The tent frame can also be formed by combining two or more pole groups, the support assembly can form an enclosed peripheral surface, two or more ceiling assemblies cross to form a larger top space, and after the tarpaulin (not shown in the figure) is connected, it is unfolded to form a tent.

[0042] Combination Figure 1 , Figure 2 As shown, it is the first embodiment of the utility model. In this embodiment, the tent frame only includes a set of pole groups to form a simple tent. The pole group includes a support assembly 1 and a ceiling assembly 2. The support assembly 1 and the ceiling assembly 2 are assembled through an X-shaped connector 3 to form a pole group. In this embodiment, the support assembly 1 includes four support rods 11, the ceiling assembly 2 includes two top rods 21, and two connection parts 31 are respectively arranged at the upper end and the lower end of the X-shaped connector 3. In this embodiment, the two connection parts 31 at the upper end of the X-shaped connector 3 form a releasable connection with the two top rods 21, and the two connection parts 31 at the lower end of the X-shaped connector 3 form a releasable connection with two of the four support rods 11; an X-shaped connector 3 is respectively arranged at both ends of the two top rods 21, and one X-shaped connector 3 is arranged with two support rods 11.

[0043] Furthermore, when the support assembly 1 and the ceiling assembly 2 are combined to form a pole group through an X-connector, when the pole group is in the unfolded state, the top support parts of the two top rods 21 are arranged in parallel. The first angle a formed between the two connection parts 31 at the upper end and the two connection parts 31 at the lower end of the X-shaped connector 3 is a fixed value. The fixed value of the first angle a of the X-shaped connector 3 can be set within 30-60°, preferably 45°, which not only ensures the planar support structure of the top, but also reserves the activity space on the surface where the X-shaped connector 3 is located. The position of the X-shaped connector 3 is set at a position close to the top, so that a door can be opened in the side area where the support rod 11 is located to form a connection with the internal space of the tent. In order to better match the support curvature of the top rod 21, a second angle b can be formed between the upper connection part 31 of the X-shaped connector 3 and the lower connection part 31 on the same side and below, and the second angle b forms an obtuse angle.

[0044] The main disassembly and assembly steps of the above tent frame (single-group frame pole group) are as follows: the X-shaped connector 3 is used as the connection structure, divided into two front and rear installation positions, each of which is provided with an X-shaped connector 3, and the two connection positions 31 at the lower end of the X-shaped connector 3 are provided with two support poles 11 in the support assembly 1 to form a ground support structure, and the front and rear two pairs of support poles 11 form four corner supports as the main support of the tent. Among them, the support 11 can form a telescopic sleeve, or it can include a method in which two rods are connected at the middle connection by a movable sleeve and then connected by an elastic pull rope, so that the support poles of the tent are folded to a shorter length. The two connection positions 31 at the upper end of the X-shaped connector 3 are each plugged with two top poles 21, and the two ends of each top pole 21 are installed on the front and rear two X-shaped connectors 3 to form a closed loop, forming a roof support structure, and then a tarpaulin is covered on the outer side of the formed tent frame to form a complete tent.

[0045] In this embodiment, the ceiling assembly 2 is supported by two top rods 21, and there is no cross connection between the two top rods 21. Instead, an independent support structure is formed at the top, and the top is supported by two 21 in a V-shape to form a support plane at the top. In conjunction with the support rods 11, the internal space of the tent is a rectangular activity space, and the activity space at the top of the tent is large.

[0046] In this embodiment, an X-shaped connector is used as the main connecting structure. The connecting portion 31 of the X-shaped connector 3 includes a socket 311. The diameter of the socket 311 is adapted to the rod end diameters of the corresponding support rod 11 and the top rod 21. The support rod 11 and the top rod 21 are assembled in a plug-in manner. The matching structure is simple, and the disassembly and assembly are convenient and quick. The X-shaped connector 3 defines a first angle a and a second angle b, and there is no problem of angle adjustment during assembly. The tent can be put into use after being plugged in. As a manually assembled tent, it has a simple structure, simple component matching, and is more convenient to disassemble and carry.

[0047] In this embodiment, the top rod 21 constituting the ceiling assembly 2 includes a crossbar 211 and two vertical rods 212. The two vertical rods 212 are respectively connected to the two ends of the crossbar 211 through a plug-in 4. The crossbar 211 located in the middle forms the top support part of the top rod 21. The vertical rods 212 and the crossbar 211 form a releasable connection mode of active plugging through the plug-in 4. By arranging the top rod 21 in sections and connecting in three sections, the connection is more stable, and the top rod 21 can be stored in three sections after disassembly, saving storage space.

[0048] Specifically, slots 411 are provided at both ends of the plug-in 4, and the diameter of the slots 411 is adapted to the rod end diameters of the corresponding crossbars 211 and vertical rods 212; the two ends of the plug-in 4 are plugged into the vertical rods 211 and the crossbars 212 through the slots 411. The middle part of the plug-in 4 is bent, and the plug-in 4 may include two connecting sections 41 to form an angle, and the top rod 21 may be bent in the middle part of the plug-in 4 to have an arc. The top rod 21 is a flexible rod, and a flexible rod member may be used, including the crossbar 211 as a flexible rod, to meet the deformation requirements of a certain arc bending during the assembly of the ceiling, and to ensure the support of the top rod 21 between the support rods 11 on both sides. The above-mentioned top rod 21 not only ensures the convenience of assembly, but also meets the arc transition connection between the ceiling assembly 2 and the support assembly 1, and avoids the breakage of the rod member caused by an overly rigid connection. At the same time, the top rod 21 is designed in the form of a middle horizontal rod 212 and two side vertical rods 212. Relative to the round arched top rod, the tent roof support has a certain angle, and the top surface can form a plane support, which can change the shape of the tent roof, making the interior space of the tent more spacious and reducing the sense of spatial oppression compared to the curved top tent.

[0049] Furthermore, in order to facilitate the folding of the tent frame, it is unnecessary to separate the support rod 11 and the top rod 21 from the X-shaped connecting member. The two connection parts at the upper and lower ends of the X-shaped connecting member can be respectively hinged at the middle of the X-shaped connecting member (not shown in the figure), and the support rod 11 and the top rod 21 are respectively fixedly connected to the connection parts. The two top rods and the two support rods connected to the X-shaped connecting member form an X-shaped distribution when the pole group is supported and unfolded. For example, each connection part can form four connecting pieces hinged at the middle of the X-shaped connecting member, the two connecting pieces at the lower end are connected to the two support rods 11 in the upper support assembly 1, and the two connecting pieces at the upper end are connected to the two top rods 21. The support rod 11 and the top rod 21 form a rotatable connection on the X-shaped connecting member. When the pole group is folded, the top rod and the support rod can be directly rotated, and the support rod can be merged and folded together toward the top rod, and finally folded together into a bundle of rods, thereby facilitating the folding of the pole group into a small volume. When the pole assembly is unfolded, the top pole or the support pole connected in the X-connector can be fixed due to the pulling effect of the tent cloth.

[0050] Combination Figure 3 , 4 As shown, it is the second embodiment of the utility model. The difference between this embodiment and the previous embodiment is that the tent frame in this embodiment includes the above-mentioned two groups of pole groups, and the two groups of pole groups are cross-arranged to enclose and form a kind of circular tent. Among them, the top support parts of the ceiling components 2 of the two groups of pole groups will form a cross. Since the support components 1 of each group of pole groups respectively include two pairs of support poles 11 arranged oppositely, a pair of support poles in a pole group is adjacent to a pair of support poles in another pole group. Through the cross-cooperation of the two groups of pole groups, a tent with four groups of support legs is formed, and the tent space is larger.

[0051] Combination Figure 5 , Figure 6 As shown, it is the third embodiment of the utility model. In this embodiment, in order to simplify the top structure of the tent, the tent ceiling assembly 2 directly includes two top rods 21. The two ends of the two top rods 21 in the same pole group are each equipped with an X-shaped connector 3. One X-shaped connector 3 is equipped with two support rods 11. The two ends of each top rod 21 are installed on the front and rear two X-shaped connectors 3 to form a closed loop, forming a roof support structure. The top rod 21 forms a flexible rod to meet the deformation requirements of a certain curvature during the assembly of the ceiling. It is connected between the two X-shaped connectors 3 to form an arc-shaped arch rod to support the top of the tent. The first angle a between the two connecting parts 31 at the upper end of the X-shaped connector 3 and the two connecting parts 31 at the lower end can be set to 45°, and the second angle b between the upper end connecting part 31 of the X-shaped connector 3 and the lower end connecting part 31 on the same side can form an obtuse angle greater than 135°. The tent frame in this embodiment also includes two groups of cross-arranged tents that can be enclosed to form a circular tent, wherein the top poles 21 of the ceiling assemblies 2 of the two groups of poles are cross-arranged.

[0052] Combination Figure 7 , Figure 8 As shown, it is the fourth embodiment of the utility model. The difference between this embodiment and the above embodiments is that in the pole group of the tent frame of this embodiment, the pole group includes a support assembly and a ceiling assembly, each support assembly also includes four support rods 11, and the ceiling assembly includes only one top rod 21. Therefore, the support assembly and the ceiling assembly are assembled through a Y-shaped connector 5 to form a pole group, and the Y-shaped connector 5 is provided with a connection portion 51 at the upper end and two connection portions 51 at the lower end. One connection portion 51 at the upper end of the Y-shaped connector 5 is connected to the top rod 21, and two connection portions 51 at the lower end of the Y-shaped connector 5 are connected to two of the four support rods 11; one Y-shaped connector 5 is configured at each end of the top rod 21, and one Y-shaped connector 5 is configured with two support rods 11.

[0053] In this embodiment, in the Y-shaped connector 5, a connection part at the upper end forms a releasable connection with the top rod 21, and two connection parts at the lower end form a releasable connection with two of the four support rods 11. Each connection part 51 includes a socket 511, and the diameter of the socket 51 is adapted to the rod end diameter of the corresponding support rod 11 and the top rod 21, so as to form a releasable connection for active plugging. The third angle c formed between the two connection parts 51 at the lower end of the Y-shaped connector 5 can be a fixed value, and the fixed value of the third angle c is set within 30-60°, preferably 45°. The top rod 21 forms a flexible rod to meet the deformation requirements of a certain curvature bending during the assembly of the ceiling, and is connected between the two X-shaped connectors 3 to form an arc-shaped arch rod to support the top of the tent. In order to better match the support curvature of the top rod 21, a fourth angle d can be formed between the upper connection part 51 and the lower connection part 51 in the Y-shaped connector 5, and the fourth angle d forms an obtuse angle. Of course, the top rod 21 in this embodiment can also adopt the above-mentioned three-section connection method, which will not be described in detail here.

[0054] In this embodiment, the tent frame also includes two groups of pole groups that are cross-coordinated, and the two top poles 21 of the two groups of pole groups form a cross; the supporting components of each group of pole groups include two pairs of support poles 11 arranged opposite to each other, and a pair of support poles 11 in a pole group is adjacent to a pair of support poles 11 in another pole group, and they are combined to form a tent with four groups of supporting feet, so that the tent space is larger and the tent roof structure is simpler.

[0055] Furthermore, the two connection parts at the lower end of the Y-shaped connecting member can be respectively hinged in the Y-shaped connecting member and located on both sides below the upper connection part (not shown in the figure), and the two connection parts at the lower end form a rotatable connection. The support rod and the top rod are respectively fixedly connected to the connection parts, and a top rod and two support rods connected to the Y-shaped connecting member form a Y-shaped distribution when the rack rod group is supported and unfolded. For example, the top rod can be fixedly connected to the connection part at the upper end of the Y-shaped connecting member, and two connecting pieces are hinged on both sides of the Y-shaped connecting member. The upper ends of the support rods are respectively fixedly connected to the connecting pieces, and the two support rods can rotate relative to each other. When the rack rod group is folded, the two support rods can be directly rotated, combined and folded together or folded upward to one side of the top rod, so as to facilitate the rack rod group to be folded into a small volume. When the rack rod group is unfolded, due to the pulling effect of the tent cloth, the top rod or support rod connected to the Y-shaped connecting member can be fixed.

[0056] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
