Description

[Technical field]

[0001] The present invention relates to the technical field of tents, and more particularly to a dome tent frame. [Background technology]

[0002] Tents are essential when doing outdoor activities, and they not only protect people from wind, rain, sunlight, and insects such as mosquitoes, but also provide outdoor enthusiasts with a relatively comfortable place to rest. When choosing a tent product, consumers consider the convenience of setting up as an important factor. However, existing products often tend to emphasize portability and neglect the convenience of setting up, so the products are carried as small pieces and assembled on site when used, and in that case, a task of assembling many poles and connectors to finally configure the tent frame occurs, which is not only time-consuming and laborious, but also prone to errors. Patent Document 1 discloses an insert-type assembly tent that has a simple structure overall, is stable without loosening of the frame, but requires on-site assembly when used, making it inconvenient to set up.

[0003] [Patent Document 1] China Utility Model No. 218881798 Summary of the Invention [Problem to be solved by the invention]

[0004] Some of the conventional tent products have been designed to be portable, but they are not convenient to set up and require on-site assembly, which is not only time-consuming and labor-intensive, but also prone to errors. In order to overcome these shortcomings, the present invention provides a dome tent frame with an optimized structure that is easy to set up. [Means for solving the problem]

[0005] The technical solution of the present invention is as follows: A dome-shaped tent frame includes a central head, a plurality of central connecting poles arranged radially around the central head and hingedly connected to the central head, a plurality of side cross poles and a plurality of vertical poles, the side cross poles are connected to the central connecting pole and the vertical poles via branch connectors, the central connecting pole is hingedly connected to the branch connectors, and the side cross poles and the vertical poles are also hingedly connected to the branch connectors. The central connecting pole is connected to the central head to form a tent roof. The pole members such as the central connecting pole, the side cross poles and the vertical poles form a ground support structure and a reinforcing structure via the branch connectors, and are connected to the tent roof to form a complete dome-shaped tent frame. The central head and branch connectors are connecting nodes for pole members such as the central connecting pole, side horizontal poles, and vertical poles, and each pole member is hingedly connected to the connecting nodes so that it can be folded. Therefore, the dome tent frame of the present invention not only allows the connection between the members to be completed at the time of shipment, but also allows for easy folding and no need for removal, making it highly portable. It can also be easily unfolded when in use, eliminating the need for on-site assembly and making it easy to set up.

[0006] Preferably, the branch connector includes a connector body provided with at least three pole joints, which are hingedly connected to the connector body. The pole joints are used to connect pole members such as a central connecting pole, a side horizontal pole, and a vertical pole, and are hingedly connected to the connector body to realize the hinge connection between the pole members and the branch connector.

[0007] Preferably, a torsion spring is further provided between the pole joint and the connector body. By providing the torsion spring, it is possible to assist the pole members in spontaneously unfolding when setting up the tent, making it easier to set up.

[0008] Preferably, an upper central head is further connected to the top of the central head, to which a number of awning lifting poles are hingedly connected. This technical means is applied to a tent with a skylight, and the upper central head and the awning lifting poles form a skylight framework, to which a tent sheet is attached to form the tent awning. The opening degree of the skylight can be adjusted in cooperation with the skylight of the tent, thereby adjusting the lighting and ventilation inside the tent.

[0009] Preferably, the branch connector includes a side head and a corner head, the side horizontal pole is connected to the central connecting pole via the side head, and the side horizontal pole is connected to the vertical pole via the corner head. The side head is a connecting node between the side horizontal pole and the central connecting pole, and the side horizontal poles are connected to each other via the side head to form the horizontal side of the outer contour of the tent, which is further connected to the central connecting pole to form a T-shaped structure. Also, the side horizontal poles are connected to each other via the corner head to form the corner of the outer contour of the tent, which is further connected to the vertical pole to form a ground support structure. A stable framework is formed by combining and connecting various pole members and various branch connectors.

[0010] Preferably, the dome tent frame of the present invention further includes a canopy pole connected to the branch connector via a canopy pole joint. The canopy pole is for supporting the canopy of the tent, and the shade area can be changed by changing the elevation and depression angles of the canopy pole.

[0011] Preferably, the branch connector is provided with a canopy pole rotation shaft and a canopy pole joint socket into which the canopy pole joint can be inserted along the axial direction, and the canopy pole joint is provided with a rounded rectangular shaft hole into which the canopy pole rotation shaft is inserted. The combination of the rounded rectangular shaft hole and the canopy pole rotation shaft allows the canopy pole joint to move along the long axis of the rounded rectangular shaft hole, and when inserted into the canopy pole socket, it is locked and cannot rotate. On the other hand, when removed from the canopy pole socket, the canopy pole joint becomes rotatable together with the canopy pole.

[0012] Preferably, the vertical poles are of a segment structure, and the segments are fitted together to connect the vertical poles and locked together by the segment locking members. The vertical poles of the segment structure can be folded without disassembly, and when setting up the tent, it is only necessary to pull the segments to unfold them, improving portability and operability.

[0013] Preferably, straps are connected between the lower ends of the vertical poles. By restraining the vertical poles with the straps after the tent is deployed, the outward deployment of the vertical poles is suppressed, and the stability of the tent is improved. Effect of the Invention

[0014] The beneficial effect of this invention is to improve the convenience of tent setup. The dome tent frame of this invention can be easily folded and does not need to be disassembled, and is highly portable because the components can be completely connected before shipping. It can also be simply unfolded when in use, so no on-site assembly is required and setup is easy. [Brief description of the drawings]

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Example 1

[0018] As shown in Fig. 1, Fig. 3 to Fig. 7, the dome tent frame includes a central head 1 and four central connecting poles 2 arranged radially around the central head 1 and hinged to the central head 1. The central head 1 is composed of an integrally formed head base and connecting plates, and four central connecting pole joints 16, and the connecting plates are fixed vertically to the head base, and there are four of them arranged in a cross shape. One end of the central connecting pole joints 16 is a hinge portion, and the other end is a central connecting pole socket. The hinge portion is U-shaped, and the U-shaped opening is fitted to the connecting plate and passed through a nut-equipped bolt as a rotation axis, so that the four central connecting pole joints 16 are hinged to the four connecting plates of the central head 1 one by one, arranged in a cross shape. A central head torsion spring is provided between the central head 1 and the central connecting pole joint 16 to generate a repulsive force between the central head 1 and the central connecting pole joint 16, thereby providing the central connecting pole 2 with a force to deploy spontaneously.

[0019] The dome tent frame of the present invention further includes eight side horizontal poles 3 and four vertical poles 4. The side horizontal poles 3 are connected to the central connecting pole 2 and the vertical poles 4 via a branch connector, the central connecting pole 2 is hinged to the branch connector, and the side horizontal poles 3 and the vertical poles 4 are also hinged to the branch connector. The branch connector includes a side head 5 and a corner head 6. The side horizontal poles 3 are connected to the central connecting pole 2 via the side head 5 and to the vertical poles 4 via the corner heads 6. The branch connector has a connector body 7 to which a pole joint 8 is hinged, and the pole joint 8 has one end which is a hinge portion and the other end which is a pole member socket. The connector body 7 of the side head 5 is a housing structure having a casing and a cap, and the cap is fixed to the casing by a screw. A one-side axle base is integrally provided on the inside of the cap and the inside of the casing, and one axle base is formed by combining the two one-side axle bases. The axle base has an insertion groove into which the ball joint 8 can be inserted, and the axle base is provided with a rotating shaft that passes through the insertion groove. The hinge part of the ball joint 8 has an axis hole that fits the rotating shaft, and the rotating shaft passes through the axis hole, so that the ball joint 8 is hinged to the connector body 7. Three ball joints 8 arranged in a T-shape are hinged to the side head 5. Two of the ball joints 8 form an angle of 180°, and one side horizontal pole 3 is inserted into each of them. The other ball joint 8 is perpendicular to the two ball joints 8 described above, and a central connecting pole 2 is inserted into each of them. A torsion spring 9 fitted to the above-mentioned rotating shaft is further provided between the ball joint 8 and the connector body 7. The torsion spring 9 generates a repulsive force between the ball joint 8 and the connector body 7, and gives the ball joint 8 a force to deploy spontaneously. The connector body 7 of the corner head 6 includes a base plate having three integrally formed vertical plates forming a Y shape, and three pole joints 8 are connected to the corner head 6 .Unlike the pole joints 8 on the side head 5, the hinge parts of the pole joints 8 on the corner head 6 are U-shaped, and the U-shaped openings are fitted to the vertical plates and penetrated by bolts as rotation axes, so that the three pole joints 8 are hinged to the three vertical plates of the connector body 7 one by one, arranged in a Y shape. Two of the three pole joints 8 forming a Y shape form an angle of 90° between them, and a side horizontal pole 3 is inserted into both of them. A vertical pole 4 is inserted into the other pole joint 8. The angle between the pole joint 8 into which the vertical pole 4 is inserted and the two pole joints 8 into which the side horizontal poles 3 are inserted are both 135°.

[0020] The vertical pole 4 has a segment structure formed by connecting two segments, a vertical pole first segment 21 and a vertical pole second segment 22, respectively. The vertical pole first segment 21 is connected to the corner head 6, the vertical pole second segment 22 is in contact with the ground, and the vertical pole first segment 21 is fitted into the vertical pole second segment 22 and locked by the segment lock member 13. The vertical pole first segment 21 and the vertical pole second segment 22 are pipe members having an elliptical cross section. Two adjacent through holes are provided in the pipe wall of the vertical pole second segment 22. A pop-up block core provided with an elastically expandable pop-up block 19 is tightly fitted inside the end of the vertical pole first segment 21. The pop-up block 19 is exposed from one window on the pipe wall of the vertical pole first segment 21 and is located on the same side as the above-mentioned through hole. The pop-out block 19 can be exposed from one of the through holes located near the lower end between the vertical pole second segments 22 as the vertical pole first segment 21 and the vertical pole second segment 22 slide relative to each other in the axial direction. The other through hole always corresponds to the sealed outer peripheral surface of the vertical pole first segment 21, and a friction block 20 is embedded in the other through hole. The friction block 20 does not escape from the through hole because its position is restricted by the inner edge of the through hole. The segment lock member 13 is cylindrical, and is provided with a button 17 that penetrates the cylindrical wall of the segment lock member 13 in the radial direction and a cam lock plate 18 that is hinged to the segment lock member 13. The segment lock member 13 is fitted to the outside of the vertical pole second segment 22 and is positioned on the vertical pole second segment 22 by a short screw. The button 17 always corresponds to the pop-out block 19, and the cam lock plate 18 always corresponds to the friction block 20.When the first vertical pole segment 21 and the second vertical pole segment 22 slide relatively in the axial direction, the above-mentioned pop-up block 19 overlaps with the above-mentioned through hole near the lower end between the second vertical pole segments 22, and when the pop-up block 19 pops out and is exposed from the through hole, the first vertical pole segment 21 and the second vertical pole segment 22 are locked to each other, and the relative separation between the first vertical pole segment 21 and the second vertical pole segment 22 reaches its limit. At this time, when the cam lock plate 18 is tightened, the apex of the cam of the cam lock plate 18 presses the friction block 20, so that the friction force between the first vertical pole segment 21 and the second vertical pole segment 22 increases, and together with the locking effect of the pop-up block 19, the first vertical pole segment 21 and the second vertical pole segment 22 are locked to each other. When it is necessary to fold the vertical pole 4 for storage, the cam lock plate 18 is loosened and the button 17 is pressed, whereby the pop-out block 19 is pushed back into the inside of the vertical pole first segment 21 by the button 17, thereby removing the obstacle to relative movement between the vertical pole first segment 21 and the vertical pole second segment 22, and the pressure of the cam lock plate 18 against the friction block 20 is removed, thereby reducing the friction force between the vertical pole first segment 21 and the vertical pole second segment 22, thereby releasing the lock between the vertical pole first segment 21 and the vertical pole second segment 22, making it possible to fold and store the vertical pole.

[0021] A strap stator 23 to which the strap 14 is connected is fitted to the lower end of the vertical pole 4, and by connecting the strap 14 between them, all the vertical poles 4 are restrained, thereby preventing the vertical poles 4 from deploying outward and increasing the stability of the tent.

[0022] The central connecting pole 2 is connected through the central head 1 to form the tent roof. The central connecting pole 2, the side horizontal poles 3, the vertical poles 4, and other pole members are connected to each other through branch connectors to form a ground support structure and a reinforcing structure, and are further connected to the tent roof to form a complete dome-shaped tent frame. When storing the dome-shaped tent frame of the present invention, all the pivotable rod members are pivoted to a folded state and tied and fixed with ropes, so that the dome-shaped tent frame can be kept in a folded state. On the other hand, when unfolding, the rope is released, and the elastic force of each corresponding torsion spring is acting, so that only a small force is required to unfold each pivotable pole member to completely push out the tent frame, and the area occupied by the fully unfolded tent frame on the ground is a square.

[0023] Example 2

[0024] As shown in FIG. 2 and FIG. 8 to FIG. 12, an upper central head 10 is further connected to the top of the central head 1, to which four awning lifting poles 11 are hingedly connected. The upper central head 10 includes an upper central head base plate and an awning lifting pole joint, and a hinge base having four joint slots is integrally provided on the upper surface of the central head base plate. The awning lifting pole joint has a hinge portion at one end and a lifting pole socket at the other end into which the awning lifting pole 11 is inserted. Axle holes are provided in both the joint slot and the hinge portion, the hinge portion of the awning lifting pole joint is inserted into the joint slot, a bolt is passed through the joint slot and the axial hole of the hinge portion, and a lock nut is provided on the exposed end of the bolt. The upper central head 10 and the central head 1 are fixed by a center bolt that passes through them and a nut for the center bolt, and thus the upper central head 10 and the central head 1 are arranged coaxially vertically. Four pole joints 8 are connected to the corner head 6, and the hinge parts of three of the pole joints 8 are U-shaped. The U-shaped openings are fitted to the vertical plates and penetrated by bolts as rotation axes, so that the three pole joints 8 are hinged to the three vertical plates of the connector body 7 one by one, arranged in a Y shape. Two of the three pole joints 8 forming a Y shape form an angle of 90° between them, and a side horizontal pole 3 is inserted into both of them. A vertical pole 4 is inserted into the other pole joint 8. The angle between the pole joint 8 into which the vertical pole 4 is inserted and the two pole joints 8 into which the side horizontal poles 3 are inserted is both 135°. A canopy pole joint 15 into which a canopy pole 12 is inserted is further provided on the upper surface of the pole joint 8 into which the vertical pole 4 is inserted, and the canopy pole 12 is also connected to the corner head 6. The canopy poles 12 are for supporting the canopy portion of the tent, and the sunshade area can be changed by changing the elevation / depression angle of the canopy poles 12. The rest is the same as in the first embodiment.

[0025] The upper central head 10 and the central head 1 form a double structure. The dome-shaped tent frame according to the present invention has an opening at the top of the tent to which the tent sheet is attached. The awning lifting pole 11 on the upper central head 10 forms an awning that covers the skylight when the tent sheet is attached. The inclination of the awning lifting pole 11 can be changed by adjusting the lock nut on the hinge base bolt on the central head base plate, thereby adjusting the lighting and ventilation of the skylight.

[0026] Example 3

[0027] As shown in Figures 13 to 15, the pole joint 8 into which the vertical pole 4 of the branch connector is inserted is provided with a canopy pole rotation shaft and a canopy pole socket 24 into which the canopy pole joint 15 can be axially inserted. The canopy pole joint 15 is provided with a rounded rectangular shaft hole 25 into which the canopy pole rotation shaft is inserted. The rest is the same as in Example 2.

[0028] By combining the rounded rectangular shaft hole 25 with the canopy pole rotation shaft, the canopy pole joint 15 can move along the long axis of the rounded rectangular shaft hole 25 to change the distance between the end point of the canopy pole joint 15 and the rotation shaft. When the canopy pole joint 15 is pivoted to the limit position and the outside of the canopy pole joint 15 abuts against the inner wall of the canopy pole socket 24, if the canopy pole joint 15 is pushed axially into the canopy pole socket 24 and the canopy pole rotation shaft reaches the distal end of the rounded rectangular shaft hole 25, the ends of the canopy pole joint 15 abut against the inner walls on both sides of the canopy pole socket 24, and sufficient rotation space is not secured, so the canopy pole joint 15 or the canopy pole 12 inserted therein is locked and cannot rotate. On the other hand, since there is a gap between the end of the canopy pole joint 15 extracted from the canopy pole socket 24 and the inner wall of the canopy pole socket 24, the canopy pole joint 15 is able to rotate together with the canopy pole 12. The rest is the same as in the second embodiment.
