Description

An arched tent bracket Technical Field

[0001] The utility model relates to the technical field of tents, and more particularly to an arched tent support. Background Art

[0002] In outdoor activities, tents are indispensable equipment. They not only provide shelter from wind and rain, sun and mosquitoes, but also provide a relatively comfortable resting place for outdoor enthusiasts. Whether it is easy to install is a key factor that consumers consider when choosing a tent product. However, existing products often focus on portability and neglect installation convenience, so that the products are carried in the form of bulk parts, and then assembled on site when used. During the assembly, a large number of rods and connectors are assembled together to form a tent frame. This process is time-consuming and labor-intensive, not only troublesome but also prone to errors. The utility model patent with publication number CN218881798U discloses a plug-in assembly tent. Although the overall structure of the tent is simple, the frame is stable and not loose, it still needs to be assembled on site when used, which is inconvenient to install.

[0003] Utility Model Content

[0004] Some existing tent products have sacrificed installation convenience in pursuit of portability and require on-site assembly and construction, which is time-consuming and labor-intensive, not only troublesome but also prone to errors. To overcome these defects, the utility model provides an arched tent bracket with an optimized structure for easy installation.

[0005] The technical solution of the utility model is: an arched tent stand, comprising a central disk and a plurality of central connecting rods, the central connecting rods being radially arranged around the central disk and hingedly connected to the central disk; the arched tent stand also comprising a plurality of side crossbars and a plurality of vertical poles, the side crossbars being connected to the central connecting rod and the vertical poles via bifurcated connectors, the central connecting rod being hingedly connected to the bifurcated connectors, and the side crossbars and vertical poles being hingedly connected to the bifurcated connectors. The central connecting rod is connected via the central disk to form a tent roof, and the central connecting rod, the side crossbars, and the vertical poles are connected to each other via bifurcated connectors to form a ground support structure and reinforcement structure, which are then connected to the tent roof to form a complete arched tent stand. The central disk and the bifurcated connectors serve as connecting nodes for the central connecting rod, the side crossbars, and the vertical poles. Because each rod is hinged and foldable at the connecting nodes, the arched tent stand can be connected to each other at the factory and can be easily folded, without disassembling and having good portability. When in use, it can be unfolded without the need for on-site installation, making it easy to install.

[0006] Preferably, the bifurcated connector includes a connector body having at least three rod joints hingedly connected to the connector body. The rod joints are used to connect rods such as a central connecting rod, side crossbars, and vertical rods. The rod joints are hingedly connected to the connector body, thereby achieving an articulated connection between the rods and the bifurcated connector.

[0007] Preferably, a torsion spring is provided between the rod joint and the connector body. The torsion spring can help the rod to unfold automatically when the tent is erected, making installation easier.

[0008] Preferably, the center pan is further connected to an upper center pan, to which a plurality of roof levers are hingedly connected. This technical solution is suitable for tents with skylights. The upper center pan and roof levers form the roof frame, which, when fitted with a tarpaulin, forms the tent's roof. The upper center pan and roof levers cooperate with the tent's skylight to adjust the skylight's opening, thereby adjusting the lighting and ventilation conditions inside the tent.

[0009] Preferably, the bifurcated connectors include side pan heads and corner pan heads, with the side crossbars connecting to the center connecting bar via the side pan heads, and the side crossbars connecting to the vertical poles via the corner pan heads. The side pan heads serve as the connecting nodes between the side crossbars and the center connecting bar. The side crossbars, when connected to each other via the side pan heads, form the horizontal sides of the tent's outer contour, which are then connected to the center connecting bar to form a T-shaped structure. The side crossbars, when connected to each other via the corner pan heads, form the corners of the tent's outer contour, which are then connected to the vertical poles to form a ground support structure. A stable frame is formed by combining various rods and various bifurcated connectors.

[0010] Preferably, the arched tent support further comprises an eaves rod, which is connected to the bifurcated connector via an eaves rod joint. The eaves rod is used to support the eaves of the tent, and the sunshade area can be changed by changing the elevation angle of the eaves rod.

[0011] Preferably, the bifurcated connector is provided with an eaves rod rotating shaft and an eaves rod joint bayonet into which the eaves rod joint is axially inserted. The eaves rod joint is provided with a waist-shaped shaft hole, into which the eaves rod rotating shaft is inserted. The waist-shaped shaft hole cooperates with the eaves rod rotating shaft to allow the eaves rod joint to move along the long axis of the waist-shaped shaft hole. When inserted into the eaves rod bayonet, the eaves rod joint is locked and cannot rotate. Only when it is removed from the eaves rod bayonet can the eaves rod joint rotate with the eaves rod.

[0012] Preferably, the poles are segmented, with the segments nested and locked together by segment locking members. The segmented poles can be folded without disassembling, and can be stretched and unfolded when setting up the tent, thereby improving portability and ease of operation.

[0013] Preferably, a drawstring is connected between the bottom ends of the vertical poles. When the tent is unfolded, the drawstring restrains the vertical poles, restricting their outward expansion and increasing the stability of the tent.

[0014] The beneficial effects of the utility model are:

[0015] Improve the convenience of tent installation. This arched tent stand can be connected between parts at the factory and easily folded without disassembly, which has good portability. When in use, it can be unfolded without on-site assembly, making it easy to install. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The present invention will be further described below with reference to the specific embodiments of the drawings.

[0033] Example 1:

[0034] As shown in Figures 1, 3, and 7, an arched tent stand comprises a central head 1 and four central connecting rods 2 arranged radially around the central head 1 and hingedly connected to the central head 1. The central head 1 comprises an integrally formed head chassis and connecting plates, as well as four central connecting rod joints 16. The connecting plates are fixed perpendicularly to the head chassis and are arranged in a cross shape. The central connecting rod joints 16 each have a hinged portion at one end and a central connecting rod socket at the other. The hinged portion is U-shaped, snapping onto the connecting plate and pierced by a bolt with a nut, allowing the four central connecting rod joints 16 to be hinged to the four connecting plates of the central head 1 in a corresponding manner and arranged in a cross shape. A central head torsion spring is provided between the central head 1 and the central connecting rod joints 16 to maintain a repulsive force between the central head 1 and the central connecting rod joints 16, thus enabling the central connecting rods 2 to deploy automatically.

[0035] The arched tent stand also includes eight side crossbars 3 and four vertical poles 4. The side crossbars 3 are connected to the central connecting rod 2 and the vertical poles 4 via bifurcated connectors. The central connecting rod 2 is hinged to the bifurcated connectors, and the side crossbars 3 and vertical poles 4 are also hinged to the bifurcated connectors. The bifurcated connectors include side discs 5 and corner discs 6. The side crossbars 3 are connected to the central connecting rod 2 via the side discs 5, and the side crossbars 3 are connected to the vertical poles 4 via the corner discs 6. The bifurcated connectors include a connector body 7, to which a rod joint 8 is hingedly connected. The rod joint 8 has a hinged portion at one end and a rod socket at the other end. The connector body 7 of the side pan head 5 is a box-like structure, comprising an outer shell and a cover. The cover is screwed to the outer shell. Inside the cover and the outer shell, two half-axle seats are integrally formed. The two halves of the seat are joined together to form a single seat. The seat has a slot for accommodating a rod connector 8. A rotating shaft extends through the slot. The hinged portion of the rod connector 8 has an axial hole that fits the rotating shaft. The rotating shaft passes through the hole, allowing the rod connector 8 to be hinged to the connector body 7. Three rod connectors 8 are hingedly connected to the side pan head 5, arranged in a T-shape. Two rod connectors 8 form a 180° angle and each connect to a side crossbar 3. The other rod connector 8 is perpendicular to the first two rod connectors 8 and connects to a central connecting rod 2. A torsion spring 9 is installed between the rod connector 8 and the connector body 7. The torsion spring 9 is sleeved on the rotating shaft and maintains a repulsive force between the rod connector 8 and the connector body 7, enabling the rod connector 8 to deploy automatically. The connecting part body 7 of the angle pan head 6 includes a base plate, on which three vertical plates forming a Y shape are integrally provided. Three rod joints 8 are connected to the angle pan head 6. Unlike the rod joints 8 on the side pan head 5, the hinged portion of the rod joint 8 on the angle pan head 6 is U-shaped. The U-shaped mouth is adapted to be clamped on the vertical plate and penetrated by bolts as a rotating shaft, so that the three rod joints 8 are hinged to the three vertical plates of the connecting part body 7 one by one and distributed in a Y shape. The angle between two of the three rod joints 8 forming the Y shape is 90° and both are connected to the side cross bar 3, and the other rod joint 8 is connected to the vertical bar 4. The angle between the rod joint 8 connected to the vertical bar 4 and the two rod joints 8 connected to the side cross bar 3 is 135°.

[0036] The vertical rod 4 is a segmented structure, consisting of two segments connected together, namely the first vertical rod section 21 and the second vertical rod section 22. The first vertical rod section 21 is connected to the angle plate head 6, and the second vertical rod section 22 contacts the ground. The first vertical rod section 21 is adapted to be inserted into the second vertical rod section 22 and locked by the segment locking piece 13. The first vertical rod section 21 and the second vertical rod section 22 are both pipe fittings with oval cross-sections. Two adjacent through-holes are provided on the wall of the second vertical rod section 22. A spring block 19 core is tightly fitted inside the end of the first vertical rod section 21. The spring block 19 core is provided with an elastically retractable spring block 19. The spring block 19 is exposed from a window in the wall of the first vertical rod section 21 and is located on the same side as the through-hole. As the first vertical rod section 21 and the second vertical rod section 22 push and pull relative axially, the spring block 19 can overlap with the one near the bottom of the second vertical rod section 22 in the through-hole and extend out of the through-hole. The other through-hole always corresponds to the enclosed outer circumference of the first section 21 of the upright. A friction block 20 is embedded in this through-hole, restrained by the inner edge of the through-hole and prevented from disengaging. The segmented locking member 13 is cylindrical and equipped with a button 17 that radially extends through the wall of the segmented locking member 13 and a cam lock plate 18 hingedly connected to the segmented locking member 13. The segmented locking member 13 is sleeved onto the second section 22 of the upright and is positioned there via a short screw. The button 17 always corresponds to the spring block 19, and the cam lock plate 18 always corresponds to the friction block 20. When the first and second sections 21, 22 of the upright pole are pushed and pulled relative to each other axially, when the spring block 19 overlaps with the through hole near the bottom of the second section 22 and the spring block 19 springs up and emerges from the through hole, the first and second sections 21, 22 are locked, and the relative distance between the first and second sections 21, 22 reaches its limit. At this time, the cam lock plate 18 is tightened, and the high point of the cam lock plate 18 presses against the friction block 20, increasing the friction between the first and second sections 21, 22. This, together with the locking effect of the spring block 19, locks the first and second sections 21, 22. If the upright 4 needs to be folded and stowed, the cam lock piece 18 is pulled up and the button 17 is pressed. The button 17 presses the spring block 19 back into the first section 21 of the upright, thereby removing the obstacle to the relative movement between the first section 21 of the upright and the second section 22 of the upright. At the same time, since the cam lock piece 18 removes the pressure on the friction block 20, the friction between the first section 21 of the upright and the second section 22 of the upright is reduced, so that the first section 21 of the upright and the second section 22 of the upright are unlocked and can be folded and stowed.

[0037] The bottom end of the vertical pole 4 is covered with a drawstring fixing piece 23, and the drawstring fixing piece 23 is connected with a drawstring 14. The drawstrings 14 are connected between them to constrain all the vertical poles 4, limit the outward expansion of the vertical poles 4, and increase the stability of the tent.

[0038] A central connecting rod 2 is connected to the tent roof via a central head 1. The central connecting rod 2, side crossbars 3, and vertical poles 4 are interconnected via bifurcated connectors to form a ground support and reinforcement structure, which is then connected to the tent roof to form a complete arched tent frame. When the arched tent frame is folded, all the reversible rods are flipped to a folded position and secured with straps to maintain the folded position. To unfold the arched tent frame, the straps are untied and, with the elastic force of the corresponding torsion springs, a slight application of force unfolds the reversible rods, expanding the tent frame into shape. When fully unfolded, the tent frame occupies a square floor space on the ground.

[0039] Example 2:

[0040] As shown in Figures 2, 8 to 12, the top of the center pan head 1 is also connected to the upper center pan head 10, and four top cover cantilever rods 11 are hinged on the upper center pan head 10. The upper center pan head 10 includes an upper center pan head bottom plate and a top cover cantilever rod joint. A hinge seat is integrally provided on the top surface of the center pan head bottom plate, and four joint slots are provided on the hinge seat. One end of the top cover cantilever rod joint is a hinge part, and the other end is a cantilever rod socket. The top cover cantilever rod 11 is inserted into the cantilever rod socket. Axial holes are provided on the joint slot and the hinge part. The hinge part of the top cover cantilever rod joint is inserted into the joint slot and bolted through the joint slot and the axial hole of the hinge part. The exposed end of the bolt is provided with a locking nut. The upper center pan head 10 and the center pan head 1 are fixed by a central bolt with a nut, so that the upper center pan head 10 and the center pan head 1 are coaxially distributed up and down. The corner pan head 6 is connected to four rod joints 8, three of which have U-shaped hinged portions. The U-shaped openings are adapted to be snapped onto the vertical plates and penetrated by bolts as rotating shafts, so that the three rod joints 8 are hinged to the three vertical plates of the connector body 7 in a one-to-one correspondence and arranged in a Y-shape. Two of the three rod joints 8 forming the Y-shape are at an angle of 90° and are both connected to the side crossbars 3. The other rod joint 8 is connected to the vertical poles 4. The angle between the rod joint 8 connected to the vertical poles 4 and the two rod joints 8 connected to the side crossbars 3 is 135°. The upper surface of the rod joint 8 connected to the vertical poles 4 is also provided with an eaves rod joint 15. The eaves rod 12 is connected to the eaves rod joint 15, so that the eaves rod 12 is also connected to the corner pan head 6. The upper surface of the rod joint 8, which is connected to the vertical pole 4, is also provided with an eaves rod joint 15. The eaves rod 12 is connected to the eaves rod joint 15, so that the eaves rod 12 is also connected to the corner plate head 6. The eaves rod 12 is used to support the eaves of the tent. The sunshade area can be adjusted by changing the elevation angle of the eaves rod 12. The rest of the process is the same as in Example 1.

[0041] The upper center pan 10 forms a double-layer structure with the center pan 1. When the tarp is installed, a skylight is created at the top of the tent. The roof lever 11 on the upper center pan 10 forms a roof cover after the tarp is installed, shielding the skylight. By adjusting the locknut on the hinged bolt on the center pan's base plate, the inclination of the roof lever 11 can be varied, thereby adjusting the light transmission and air flow of the skylight.

[0042] Example 3:

[0043] As shown in Figures 13 to 15 , the rod joint 8 of the bifurcated connector, which is inserted into the vertical rod 4, is provided with an eaves rod rotating shaft and an eaves rod bayonet 24 for axial insertion of the eaves rod joint 15. The eaves rod joint 15 is provided with a waist-shaped shaft hole 25, into which the eaves rod rotating shaft is inserted. The remaining components are the same as those in Example 2.

[0044] The oval-shaped axis hole 25 cooperates with the eaves rod rotation axis, allowing the eaves rod joint 15 to move along the long axis of the oval-shaped axis hole 25, changing the distance between the end point of the eaves rod joint 15 and the rotation axis. When the eaves rod joint 15 is flipped to the extreme position, the outer side of the eaves rod joint 15 abuts against the inner wall of the eaves rod clamping hole 24, and the eaves rod joint 15 is axially pushed into the eaves rod clamping hole 24. The eaves rod rotation axis reaches the far point of the oval-shaped axis hole 25. At this time, the end of the eaves rod joint 15 abuts against the inner walls of the eaves rod clamping hole 24 on both sides, leaving insufficient room for rotation. Therefore, the eaves rod joint 15 and the eaves rod 12 thereon are locked and cannot rotate. After being pulled out of the eaves rod clamping hole 24, a gap is left between the end of the eaves rod joint 15 and the inner wall of the eaves rod clamping hole 24. At this time, the eaves rod joint 15 can rotate with the eaves rod 12. The rest is the same as in Example 2.

[0045] Example 4:

[0046] There are three central connecting rods 2, six side crossbars 3, and three vertical poles 4. When the tent stand is fully unfolded, the area it occupies on the ground is a triangle.

[0047] Example 5:

[0048] There are six central connecting rods 2, twelve side crossbars 3, and six vertical poles 4. When the tent stand is fully unfolded, the area it occupies on the ground is a regular hexagon.

[0049] Example 6:

[0050] The bifurcated connector only includes an angled head 6, to which four rod joints 8 are hingedly connected: the upper rod joint 8 and the lower rod joint 8. The upper rod joint 8 is used to connect to the central connecting rod 2, the lower rod joint 8 is used to connect to the vertical rod 4, and the rod joints 8 on both sides are used to connect to the side crossbars 3. The rest is the same as in Example 1.
