Detailed Implementation

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] Example 1, see Figures 1 to 3 The tent frame shown includes support legs 1 and a top frame 2. The support legs 1 are connected to and support the top frame 2. When the tent frame is in the unfolded state, covering the top frame 2 with a tarpaulin provides shelter, thus forming a tent. The tent frame also includes casters 31 connected to the support legs 1, enabling the tent to move. In this embodiment, the casters 31 are vertically movable and connected to the support legs 1. When the tent does not need to be moved, the casters 31 are driven upwards, moving them away from the bottom of the support legs 1 to avoid affecting the stability of the support legs. When the tent needs to be moved, the casters 31 are driven downwards, facilitating contact between the casters 31 and the ground.

[0033] Specifically, in this embodiment, the bottom of the support leg 1 has a downward-facing support surface 131. The roller 31 has a first state and a second state relative to the support leg 1. In the first state, the roller 31 is higher than the support surface 131, and the bottom of the roller 31 is a first distance from the support surface 131 in the vertical direction. In the first state, the roller 31 is away from the support surface 131 to ensure that the support leg 1 provides stable support. If the roller 31 is in the second state, the bottom of the roller 31 is a second distance from the support surface 131 in the vertical direction, which is less than the first distance. The roller 31 moves closer to the ground, making it easier to move the tent. In some embodiments, when the user moves the tent, the tent is tilted at a certain angle so that the roller 31 contacts the ground. By driving the roller 31 to the second state, it moves downward, and the tent can be moved by tilting it at a small angle. In some preferred embodiments, if the roller 31 is in the second state, at least part of the roller 31 is located below the support surface 131. At this time, the roller 31 contacts the ground, allowing the tent to be moved directly.

[0034] In this embodiment, if roller 31 is in the first state, roller 31 is located at a first height along the axial direction of support leg 1, and roller 31 is at a first circumferential angle around the axis of support leg 1. If roller 31 is in the second state, roller 31 is located at a second height along the axial direction of support leg 1, and roller 31 is at a second circumferential angle around the axis of support leg 1. The first height and the second height are different, and the first circumferential angle and the second circumferential angle are also different; specifically, the first height is greater than the second height. In this embodiment, when roller 31 changes from the first state to the second state, roller 31 moves downward along the axial direction of support leg 1, and roller 31 moves circumferentially along support leg 1, causing the position of roller 31 on the periphery of support leg 1 to change. Thus, roller 31 can move to the outside of support leg 1 when transitioning to the second state, facilitating movement.

[0035] In this embodiment, the tent frame includes at least three support legs 1. When the roller 31 is in the first state, a receiving space is formed between the multiple support legs 1, and the roller 31 is housed within the receiving space. This ensures the neatness of the tent and prevents the roller 31 from protruding outwards and causing interference. Specifically, see [link to documentation]. Figure 1 As shown, the tent frame has a folded state. When the tent frame is in the folded state, multiple support legs 1 are close together, and the top frame 2 is folded between the multiple support legs 1. In this embodiment, the tent frame includes four support legs 1. When the tent frame is in the folded state, the support legs 1 and the top frame 2 are folded together to form a cuboid. When the tent frame is in the folded state and the rollers 31 are in the first state, the rollers 31 are housed between the multiple support legs 1, which ensures the neatness of the structure and shape of the tent frame after folding. See also... Figure 2As shown, if the tent frame is in a folded state and the roller 31 is in the second state, the roller 31 extends to the outside of the cuboid. At this time, tilting the tent frame to one side will allow the roller 31 to contact the ground.

[0036] In this embodiment, see Figure 1 , Figure 2 As shown, the tent frame has multiple support legs 1, including a first support leg and a second support leg. The first and second support legs are spaced apart along a first direction. Both the first and second support legs have rollers 31 at their lower parts. When the rollers 31 are in a second state, the first and second support legs are positioned between the two rollers 31 along the first direction. This design improves the stability of movement. In this embodiment, see [reference needed]. Figure 2 As shown, if the tent frame is in a folded state and the rollers 31 are in the second state, the two rollers 31 are distributed on both sides of the cuboid formed by the support legs 1 and the top frame 2. In other embodiments, the tent frame is provided with more support legs 1, or the lower part of more support legs 1 is provided with rollers 31.

[0037] In this embodiment, the support leg 1 includes a leg rod 11, which extends in the vertical direction. See [reference needed]. Figure 4 As shown, the cross-section of leg 11 is quadrilateral, see [reference]. Figures 11 to 13 As shown, the first state roller 31 and the second state roller 31 are located at two opposite corners of the cross section of the leg 11. When the roller 31 switches between the first state and the second state, it rotates 180 degrees relative to the axis of the supporting leg 1. The first circumferential angle and the second circumferential angle form an angle of 180 degrees.

[0038] In this embodiment, the roller 31 can rotate around the rotation center line and can be connected to the support leg 1 in a vertically movable manner. The rotation center line extends in the vertical direction. Specifically, the rotation center line extends collinearly with or parallel to the axis of the support leg 1.

[0039] In this embodiment, the tent frame includes a wheel seat 32, and a roller 31 is connected to the support leg 1 via the wheel seat 32. Specifically, the roller 31 is rotatably connected to the wheel seat 32 via an axle 311, and the wheel seat 32 is connected to the support leg 1. In this embodiment, the wheel seat 32 can rotate around a rotation center line and is also movably connected to the support leg 1 vertically. If the roller 31 is in the second state, the wheel seat 32 extends laterally to the support leg 1, allowing the roller 31 to extend to the outside of the accommodating space. In other embodiments, the roller 31 is movably connected to the support leg 1 in other ways, for example, the axle 311 is movably connected to the support leg 1, with the roller 31 rotating around the axle 311.

[0040] In this embodiment, the wheel seat 32 is movably connected to the leg pole 11. Specifically, the wheel seat 32 is movably sleeved on the outside of the leg pole 11. Preferably, each support leg 1 includes multiple leg poles 11, which are foldable along their length. For example, the multiple leg poles 11 are slidably telescopically arranged, so that the height of the top frame 2 is adjustable in the unfolded state, and the length of the support leg 1 can be effectively reduced during folding, thereby reducing the volume of the tent frame after folding.

[0041] In this embodiment, one of the wheel seat 32 and the support leg 1 is provided with a spiral groove 321 extending spirally in the vertical direction, and the other of the two is provided with a slider 14. The slider 14 is movably inserted in the spiral groove 321 so that the wheel seat 32 can move relative to the support leg 1 along the spiral groove 321. The cooperation between the spiral groove 321 and the slider 14 provides guidance for the movement of the wheel seat 32 relative to the support leg 1.

[0042] In this embodiment, see Figure 5 , Figure 11 As shown, the wheel seat 32 is provided with a spiral groove 321, and the support leg 1 is provided with a sliding member 14. In this embodiment, the spiral groove 321 extends spirally from top to bottom around the axis of the support leg 1. If the roller 31 is in the first state, see... Figures 5 to 9 As shown, the slider 14 is located at the lower end of the spiral groove 321. If the roller 31 is in the second state, see [reference needed]. Figures 14 to 18 As shown, the slider 14 is located at the upper end of the spiral groove 321.

[0043] In this embodiment, a locking structure is provided between the wheel seat 32 and the support leg 1 to lock the two together. The locking structure includes a lock hole 324 and a locking pin. In this embodiment, the wheel seat 32 is provided with a lock hole 324, and the support leg 1 is provided with a locking pin for engaging with the lock hole 324. Specifically, the locking pin includes a first locking pin 411 and a second locking pin 412 spaced apart in the vertical direction. If the roller 31 is in a first working state, the first locking pin 411 is inserted into the lock hole 324. If the roller 31 is in a second working state, the second locking pin 412 is inserted into the lock hole 324. In this embodiment, see [reference needed]. Figure 4 , Figure 10 and Figure 19 As shown, the first locking pin 411 is located above the second locking pin 412.

[0044] In this embodiment, the first locking pin 411 and the second locking pin 412 are at different angles relative to the axis of the support leg 1. Specifically, in this embodiment, when the roller 31 switches between the first state and the second state, the wheel seat 32 rotates 180 degrees around the rotation center line, and the first locking pin 411 and the second locking pin 412 are distributed at an angle of 180 degrees.

[0045] In this embodiment, the locking structure further includes an elastic element 42, which provides the force required to drive the locking pin toward the lock hole 324. In this embodiment, the elastic element 42 is a U-shaped spring sheet, and the first locking pin 411 and the second locking pin 412 are respectively disposed on the first elastic arm 421 and the second elastic arm 422 of the elastic element 42. In this embodiment, the first locking pin 411, the second locking pin 412, and the elastic element 42 are integrally formed.

[0046] In this embodiment, see Figure 4 , Figure 10 As shown, the elastic element 42 is disposed in the rod cavity of the leg rod 11. The rod wall of the leg rod 11 is provided with a through hole 111. The first locking pin 411 and the second locking pin 412 can extend from the through hole 111 to the outside of the leg rod 11, thereby extending into the locking hole 324 of the wheel seat 32.

[0047] In this embodiment, the locking structure also includes an unlocking component 5, which is movably connected to the wheel seat 32. By driving the unlocking component 5 to move, the locking pin can be pushed out of the lock hole 324, thereby releasing the lock between the wheel seat 32 and the support leg 1. See also Figure 4 , Figure 10 and Figure 19 As shown, in this embodiment, the unlocking component 5 is rotatably connected to the wheel seat 32, and the unlocking operation is completed by driving the unlocking component 5 to rotate. Specifically, the unlocking component 5 includes a connecting part 51 and an unlocking part 52. The connecting part 51 is rotatably connected to the wheel seat 32 around the rotating shaft 53. The lock hole 324 is located on the path of the unlocking part 52 rotating around the rotating shaft 53. The user presses the unlocking part 52, drives the unlocking part 52 to rotate, and pushes the lock pin out of the lock hole 324, thereby realizing unlocking.

[0048] In other embodiments, the support leg 1 is provided with a locking hole, and the wheel seat 32 is provided with a locking pin. Specifically, the support leg 1 is provided with a first locking hole and a second locking hole. The first locking hole is located above the second locking hole in the vertical direction, and the first locking hole and the second locking hole are at different angles relative to the axis of the support leg 1. If the roller 31 is in the first working state, the locking pin is inserted into the first locking hole; if the roller 31 is in the second working state, the locking pin is inserted into the second locking hole. In other embodiments, the support leg 1 and the wheel seat 32 are locked using other methods already existing in the prior art, such as snap-fit ​​mechanisms.

[0049] In this embodiment, the lower part of the leg 11 is provided with a sleeve fitting part 15. The sleeve fitting part 15 includes a plurality of parts surrounding the outside of the leg 11. The outer contour of the cross-section of the plurality of sleeve fitting parts 15 forms a circle, thereby facilitating the wheel seat 32 to be fitted onto the outside and to form a movable connection with the support leg 1. In some embodiments, the plurality of sleeve fitting parts 15 are fixedly connected or integrally formed to form a ring.

[0050] In this embodiment, the bottom of the support leg 1 is provided with a foot 13, which extends horizontally. Specifically, the foot 13 extends laterally to the leg rod 11, and the bottom of the foot 13 has the aforementioned support surface 131. By providing the foot 13, the stability of the support leg 1 can be improved. In this embodiment, the support leg 1 provided with a roller 31 has a sleeve fitting part 15 provided on the top of the foot 13.

[0051] In this embodiment, if the roller 31 is in the first state, see [reference needed]. Figures 5 to 10 As shown, roller 31 is located above base 13. Folding roller 31 above base 13 avoids affecting the support of base 13. If roller 31 is in the second state, see... Figures 14 to 19 As shown, the roller 31 is located horizontally on one side of the base 13, allowing the tent to be moved using the roller 31 in this state. In this embodiment, during the transition of the roller 31 to the second state, the roller 31 moves outward from the base 13 and downward.

[0052] In some embodiments, if roller 31 is in the second state, the bottom of roller 31 is still higher than the bottom of foot 13, or the bottom of roller 31 is level with the bottom of foot 13. To move the tent, it is still necessary to tilt the tent to one side. However, since roller 31 moves downward during the transition to the second state, the tent can be moved by tilting it at a smaller angle. In other embodiments, if roller 31 is in the second state, at least part of roller 31 moves below foot 13, at which point the tent can be moved directly.

[0053] In this embodiment, the bottom of each of the four support legs 1 is provided with a foot 13 to improve the stability of the support. In some embodiments, if the tent frame is in a folded state, multiple feet 13 are connected to each other or multiple feet 13 abut against each other, thereby fixing each support leg 1 together and preventing the support legs 1 from shifting to each other, thus facilitating storage or transfer.

[0054] In this embodiment, if the tent frame is in a folded state, the two base legs 13 can be connected to each other. Specifically, see [link to documentation]. Figures 1 to 3 As shown, one of the two adjacent feet 13 is provided with a first connecting hole 1321 and the other is provided with a second connecting hole 1331. The tent frame includes a connecting pin 611, which can be inserted into the first connecting hole 1321 and the second connecting hole 1331, so that the two feet 13 are connected to each other.

[0055] Specifically, one of the base feet 13 is provided with a first connecting ring 132, which has a first connecting hole 1321; the other base foot 13 is provided with a second connecting ring 133, which has a second connecting hole 1331. When the tent frame is in a folded state, the first connecting hole 1321 and the second connecting hole 1331 are interconnected. In this embodiment, there are two second connecting rings 133 spaced apart. When the tent frame is in a folded state, the first connecting ring 132 is inserted between the two second connecting rings 133.

[0056] In this embodiment, the tent includes a protective cover 6. When the tent frame is folded, the protective cover 6 can cover the top of the tent frame and extend downwards from the top of the tent frame. The protective cover 6 has a connector 61, which can be connected to the support leg 1, the roller 31, or the wheel seat 32 to form a fixed structure. In this embodiment, the connector 61 includes the aforementioned connecting pin 611. The protective cover 6 is connected to the base 13 through the connecting pin 611, which can fix itself while connecting the two bases 13 through the connecting pin 611. Specifically, the connector 61 also includes a connecting strap 612, which connects the main body of the protective cover 6 to the connecting pin 611.

[0057] In this embodiment, the protective cover 6 also includes a handle 62, which is located on the upper part of the protective cover 6, allowing the user to move the tent frame by using the handle 62.

[0058] Example 2, see Figure 20 As shown, the main difference between this embodiment and Embodiment 1 is that in this embodiment, one of the wheel seat 32 and the support leg 1 is provided with a guide groove 322, and the other is provided with a sliding member 14. The guide groove 322 includes a first groove segment 3221 and a second groove segment 3222 that are interconnected. The first groove segment 3221 is an arc extending around the rotation center line, and the second groove segment 3222 extends in the vertical direction. The sliding member 14 is movably inserted in the guide groove 322 so that the wheel seat 32 can move relative to the support leg 1 along the guide groove 322. In this embodiment, the wheel seat 32 is provided with a guide groove 322, and the support leg 1 is provided with a sliding member 14.

[0059] In this embodiment, the lower ends of the first groove segment 3221 and the second groove segment 3222 are interconnected. When driving the roller 31 to transition to the second state, the wheel seat 32 first moves along the first groove segment 3221, causing the roller 31 to rotate relative to the support leg 1 around the rotation center line. Then, the wheel seat 32 drives the roller 31 to move downward. In other embodiments, the upper ends of the first groove segment 3221 and the second groove segment 3222 are interconnected. When driving the roller 31 to transition to the second state, the wheel seat 32 first drives the roller 31 to move downward. Then, the wheel seat 32 moves along the first groove segment 3221, causing the roller 31 to rotate relative to the support leg 1 around the rotation center line.

[0060] Example 3, see Figure 21 As shown, the main difference between this embodiment and Embodiment 2 is that in this embodiment, the guide groove 322 further includes a third groove segment 3223, which extends horizontally. Preferably, the third groove segment 3223 is an arc extending around the rotation center line, and the upper end of the third groove segment 3223 is interconnected with the upper end of the second groove segment 3222. See also Figure 21 As shown, in this embodiment, the first groove segment 3221 and the third groove segment 3223 are located on the same side of the second groove segment 3222, and the guide groove 322 forms a C-shape. In this embodiment, the third groove segment 3223 is shorter than the first groove segment 3221. When the roller 31 transitions from the first state to the second state, the slider 14 moves from the first groove segment 3221 through the second groove segment 3222 and finally into the third groove segment 3223. The upper and lower groove walls of the third groove segment 3223 can restrict the up-and-down movement of the wheel seat 32. In other embodiments, the third groove segment 3223 is longer than the first groove segment 3221. When the roller 31 transitions from the first state to the second state, the slider 14 moves from the third groove segment 3223 through the second groove segment 3222 and finally into the first groove segment 3221. The upper and lower groove walls of the third groove segment 3223 can restrict the up-and-down movement of the wheel seat 32.

[0061] Example 4, see Figure 22 As shown, the main difference between this embodiment and embodiment 3 is that in this embodiment, the first groove segment 3221 and the third groove segment 3223 are located on different sides of the second groove segment 3222, and the guide groove 322 forms a Z-shape. When the roller 31 switches between the first state and the second state, the slider 14 moves along the guide groove 322, thereby moving from the first groove segment 3221 to the third groove segment 3223, or from the third groove segment 3223 to the first groove segment 3221.

[0062] Example 4 differs from the previous examples in that: in this example, the support leg 1 includes a leg rod 11 and a support base 12. The leg rod 11 extends vertically, and the support base 12 is located at the lower end of the leg rod 11. A roller 31 is movably connected to the support base 12, and the support base 12 is detachably connected to the leg rod 11. In this example, the support base 12 and the roller 31 constitute a movable support for the tent. By fixing it to the lower part of the leg rod 11, it provides support and allows for movement of the tent using the roller 31 when needed. Specifically, the support base 12 can be detachably connected to the leg rod 11 using a plug-in or other method.

[0063] Preferably, in this embodiment, the roller 31 also has the first and second states described in the above embodiments. In the first state, the roller 31 is located at a first height along the axial direction of the support base 12, and the roller 31 is at a first axial angle along the axis of the support base 12. In the second state, the roller 31 is located at a second height along the axial direction of the support base 12, and the roller 31 is at a second circumferential angle along the axis of the support base 12. The first height and the second height are different, and the first circumferential angle and the second circumferential angle are different. Specifically, in this embodiment, the roller 31 can both rotate around the rotation center line and move up and down to connect with the support base 12.

[0064] More preferably, the movable support includes a wheel seat 32, which is movably connected to the support base 12. A spiral groove 321 and a sliding member 14, as described in Embodiment 1, can be provided between the wheel seat 32 and the support base 12. For example, the wheel seat 32 is provided with a spiral groove 321, and the support base 12 is provided with a sliding member 14. In other embodiments, a guide groove 322 and a sliding member 14, as described in Embodiment 2 or Embodiment 3, can be provided between the wheel seat 32 and the support base 12. For example, the wheel seat 32 is provided with a guide groove 322, and the support base 12 is provided with a sliding member 14.

[0065] Preferably, the bottom of the support base 12 is provided with a foot 13, which can improve the stability of the movable support. If the roller 31 is in the first state, the roller 31 is located above the foot 13. If the roller 31 is in the second state, the roller 31 is located on one side of the foot 13 in the horizontal direction.

[0066] See Figures 5 to 22 As shown, the leg 11 in the figure can be regarded as a component of the support base 12. Thus, the leg 11, the base 13, and other structures in the figure together constitute the support base 12 of this embodiment. Combined with the roller 31, wheel seat 32, and other structures shown in the figure above, they can be regarded as the movable support of this embodiment. More preferably, the movable support also includes a sleeve fitting part 15, a first connecting ring 132, a second connecting ring 133, and other structures.

[0067] Preferably, a locking structure for locking the support base 12 and the wheel seat 32 is provided, and the locking structure can refer to the locking pin and locking hole in Embodiment 1. Specifically, a locking pin is provided on one of the support base 12 and the wheel seat 32, and a locking hole is provided on the other. The locking structure also includes an elastic element, which can be provided in the manner described in Embodiment 1.

[0068] In summary, the tent frames of all the above embodiments can drive the rollers 31 upward and house them in the accommodating space between the multiple support legs 1 when the tent does not need to be moved, and can drive the rollers 31 downward and move them to the outside of the accommodating space when the tent needs to be moved, so that the user can move the tent more conveniently and more stably.
