[0033] The present application provides a fence comprising a fence frame 10 and a fabric cover, the fabric cover covering the sides and bottom of the fence frame 10. The fence frame 10 constitutes the basic structure of the fence, primarily providing support, and can be made of a durable material (such as metal or hard plastic). The fabric cover can be made of cotton, synthetic gauze, polyethylene (PE), or other materials. The fabric cover, when applied to the fence frame 10, forms a relatively enclosed space suitable for creating a children's play area or a pet activity area. The fabric cover is removable from the fence frame 10, allowing users to replace or clean it as needed to maintain cleanliness and hygiene.

[0034] See also Figure 1 The fence frame 10 includes four side structures arranged along the circumference to form a rectangular structure. Of course, in other embodiments, the side structures can also be three, five, six, etc. The side structures include two transverse struts 100, two vertical struts 200, two diagonal struts 300, and two first connecting rods 410. Among them, adjacent side structures share the vertical struts 200. For example, there are four vertical struts 200, which are arranged at intervals along the circumference of the fence frame 10.

[0035] See also Figure 1 The two transverse struts 100 of each side structure are arranged in the transverse direction, and the distal ends of the two are detachably connected to the upper ends of the two vertical struts 200, and the adjacent ends of the two are rotatably connected relative to each other. The two transverse struts 100 are respectively detached from the upper ends of the two vertical struts 200 and approach each other by rotating downward; the distal ends of the two diagonal struts 300 are respectively arranged to be rotatable relative to the lower ends of the two vertical struts 200, and the adjacent ends of the two are rotatably connected to the intersection of the two transverse struts 100, and the two diagonal struts 300 are respectively approached to each other by rotating upward relative to the lower ends of the two vertical struts 200; the distal ends of the two first connecting rods 410 are respectively arranged to be rotatably connected to the two diagonal struts 300, and the adjacent ends of the two are rotatably connected relative to each other.

[0036] See also Figures 1 to 3 The fence frame 10 of the embodiment of the present application has an expanded state and a folded state, which is convenient for users to use and store. Figure 1In the unfolded state, the vertical struts 200 provide vertical support and, together with the transverse struts 100, support the height and shape of the fence frame 10. The diagonal struts 300, together with the vertical struts 200 and the transverse struts 100, form a triangle, ensuring the relative stability of the vertical struts 200 and the transverse struts 100. The two first connecting rods 410 form a triangle with the two diagonal struts 300, further improving the stability of the two diagonal struts 300 and dispersing the load borne by the diagonal struts 300, thereby improving the bearing capacity of the entire structure. Figure 3 In the collapsed state, the transverse struts 100 rotate downward to move closer together, while the diagonal struts 300 rotate upward to move closer together. The first connecting rods 410 also rotate accordingly to accommodate the collapse of the diagonal struts 300. In this way, the fence frame 10 can be folded into a compact form that is easy to carry and store.

[0037] Furthermore, the fabric cover can cover the inner side of the fence frame 10, with an open upper end and a closed lower end. Specifically, the fabric cover is a rectangular structure that matches the fence frame 10. A sleeve is vertically provided at the corner of the fabric cover, and the sleeve is sleeved on the outer periphery of the vertical support rod 200 to achieve the connection between the fabric cover and the vertical support rod 200. A connecting portion is provided on the upper part of the fabric cover, and the connecting portion is formed by extending the upper part of the fabric cover. The connecting portion and the fabric cover are respectively provided with zippers that cooperate with each other. The upper part of the fabric cover is fixed to the transverse support rod 100 by the connecting portion and the zipper.

[0038] See also Figure 1 In some embodiments, the side structure of the fence frame 10 also includes two second connecting rods 420, each of which has its distal ends pivotally connected to the two transverse struts 100 and its adjacent ends pivotally connected to the intersection of the two first connecting rods 410. Thus, the two second connecting rods 420 and the two transverse struts 100 form a triangle, improving the stability of the two first connecting rods 410 when deployed. The second connecting rods 420 also further distribute the load borne by the fence frame 10, thereby enhancing the stability of the entire structure.

[0039] See also Figure 1Furthermore, when the side structure of the fence frame 10 is in the expanded state, the two first connecting rods 410 are arranged in parallel with the two transverse struts 100. The parallel-arranged first connecting rods 410 and transverse struts 100 form a more stable framework mechanically, which can more effectively disperse and resist external forces, thereby reducing the risk of structural deformation and damage. In contrast, if the first connecting rods 410 and the transverse struts 100 are not parallel, unnecessary torque or shear force will be generated between them, which can easily lead to structural instability. Moreover, arranging the two first connecting rods 410 in parallel with the two transverse struts 100 is conducive to a more even distribution of the load borne by the fence frame 10. When the load is evenly distributed, the stress borne by each component will be reduced, thereby improving the bearing capacity of the entire structure.

[0040] See also Figure 4 In some embodiments, the side structure of the fence frame 10 is defined to have a central axis Z extending in the vertical direction, the transverse struts 100 are defined to have a center point O, and the diagonal struts 300 are defined to have a center point P. Among them, the two transverse struts 100, the two diagonal struts 300, the two vertical struts 200, the two first connecting rods 410, and the two second connecting rods 420 are all symmetrically arranged based on the central axis. In this way, it can be ensured that the fence frame 10 has uniform support and stability in both the horizontal and vertical directions. This symmetrical structure can effectively resist the influence of various external forces and environmental factors, and maintain the shape and stability of the fence frame 10. Moreover, the symmetrically arranged components enable the fence frame 10 to distribute the load more evenly when subjected to force, thereby reducing the stress borne by each component due to the symmetrical distribution, thereby improving the bearing capacity of the entire structure.

[0041] Among them, in the left and right directions of the side structure of the fence frame 10, the distance h1 between the distal ends of the two first connecting rods 410 is less than the distance h2 between the two center points P, and the distance between the distal ends H1 of the two second connecting rods 420 is the same as the distance H2 between the two center points O. The first connecting rod 410 and the second connecting rod 420 are closer to the central axis Z, which means that the lengths of the first connecting rod 410 and the second connecting rod 420 can be relatively short, which not only reduces the amount of material used and reduces manufacturing costs, but also helps to reduce the overall weight of the fence frame 10 and improve the convenience of installation. In addition, the first connecting rod 410 and the second connecting rod 420 are relatively more compact in the side structure, making the central axis Z of the side structure of the fence frame 10 tighter, which helps to enhance the rigidity and stability of the intersection of the two transverse struts 100 and the two diagonal struts 300, so that the fence frame 10 can better resist external loads and deformation and maintain the overall stability and safety of the structure.

[0042] Furthermore, the two first connecting rods 410 are connected to the outer surfaces of the two diagonal bracing rods 300 , and the two second connecting rods 420 are connected to the outer surfaces of the transverse bracing rods 100 and the outer surfaces of the two first connecting rods 410 .

[0043] Please refer to Figure 1 and Figure 8 In some embodiments, the side structure of the fence frame 10 further includes an intermediate connector 500, which is connected to the adjacent ends of the two transverse struts 100 and is rotatably connected relative to the intermediate connector 500. The adjacent ends of the two diagonal struts 300 are also rotatably connected to the intermediate connector 500. The intermediate connector 500 is a straight rod structure with openings at both ends and the bottom. Four connecting points 510 are sequentially arranged along the length of the intermediate connector 500 for connecting the two transverse struts 100 and the two diagonal struts 300. Specifically, the two transverse struts 100 are inserted from both ends of the intermediate connector 500 and rotatably connected to the two connecting points 510 located on the outside. The upper ends of the two diagonal struts 300 are inserted from the bottom of the intermediate connector 500 from two directions and rotatably connected to the two connecting points 510 located in the center.

[0044] See also Figures 1 to 3 In some embodiments, the fence frame 10 further includes an upper corner connector 600 and a lower corner connector 900, wherein four upper corner connectors 600 and four lower corner connectors 900 can be provided, and connect two adjacent side structures together. The distal ends of the transverse struts 100 of the two adjacent side structures share a vertical strut 200 through the upper corner connector 600. The upper corner connector 600 is mounted on the vertical strut 200 and can slide relative to the vertical strut 200 in the height direction. The transverse struts 100 of the two adjacent side structures are rotatably connected to the upper corner connector 600, and the upper corner connector 600 slides on the vertical strut 200 to achieve folding. A lower corner connector 900 is fixed to the lower end of a vertical strut 200, and the lower ends of the diagonal struts 300 of the two adjacent side structures are connected to a vertical strut 200 through the lower corner connector 900, and the lower ends of the diagonal struts 300 of the two adjacent side structures are rotatably connected to the lower corner connector 900 so as to be able to be folded.

[0045] Please refer to Figures 5 to 7The upper corner connector 600 includes a fixing member 610 and a locking member 620. The locking member 620 is detachably connected to the fixing member 610. The fixing member 610 is slidably mounted on the vertical support rod 200. The transverse support rod 100 is detachably connected to the upper end of the vertical support rod 200 via the fixing member 610. The locking member 620 is used to relatively fix the fixing member 610 and the vertical support rod 200 in the deployed state. It is understandable that the fixing member 610 may have a mounting hole 611a, and the vertical support rod 200 is relatively slidably disposed in the mounting hole 611a. The locking member 620 may be a threaded fastener (such as a bolt, screw, etc.). The fixing member 610 may be provided with a bolt hole, and the vertical support rod 200 and the fixing member 610 are fastened together by the threaded fastener. The locking member 620 can also be formed as a buckle structure on the fixing member 610, and the vertical support rod 200 is fixed to the fixing member 610 by the buckle. Here, the present application does not limit the specific form of the fixing member 610 and the locking member 620, and the fixing member 610 and the locking member 620 can be an integral structure or a separate structure.

[0046] See also Figure 9 In some embodiments, the fixing member 610 includes a main body 611 and a positioning portion 612, the main body 611 is provided with a mounting hole 611a, and the outer wall of the main body 611 is provided with a positioning hole 611b connecting the mounting hole 611a and the outside, wherein the vertical support rod 200 is slidably arranged in the mounting hole 611a, and the upper end of the vertical support rod 200 is provided with a accommodating cavity 200a with an upper opening, and the vertical support rod 200 is provided with a fixing hole 200b connecting the accommodating cavity 200a and the outside, wherein the fixing hole 200b is located in the upper area of ​​the vertical support rod 200. When the side structure is in the expanded state, the fixing hole 200b is aligned with the positioning hole 611b. At this time, the locking member 620 is extended from the opening into the accommodating cavity 200a, and the fixing hole 200b and the positioning hole 611b are penetrated to fix the fixing member 610 relative to the vertical support rod 200.

[0047] Specifically, when the fence frame 10 is unfolded, the fixing member 610 is slid upward along the vertical support rod 200. When it slides to the desired position, the locking member 620 is extended from the opening into the accommodating cavity 200a, and the fixing hole 200b, the installation hole 611a and the positioning hole 611b are penetrated to fix the fixing member 610 relative to the vertical support rod 200. In this process, the locking member 620 is completely accommodated in the accommodating cavity 200a, realizing a hidden installation; when the fence frame 10 needs to be folded, the locking member 620 is returned to the accommodating cavity 200a, and the fixing member 610 can be slid downward along the vertical support rod 200.

[0048] See also Figure 7In some embodiments, the locking member 620 includes a locking portion 621 and a first limiting portion 622. The locking portion 621 is configured to extend into the positioning hole 611b to secure the fixing member 610 relative to the vertical support rod 200. The first limiting portion 622 is connected to one side of the locking portion 621 and abuts against the inner wall of the vertical support rod 200. The shape and size of the locking portion 621 can match the positioning hole 611b and the fixing hole 200b to ensure that it can be smoothly inserted into and fixed in the fixing hole 200b and the positioning hole 611b. The first limiting portion 622 abuts against the inner wall of the vertical support rod 200, preventing the locking member 620 from excessively moving or falling out of the positioning hole 611b, thereby enhancing the fixing effect of the locking member 620 on the fixing member 610 and the vertical support rod 200. The first limiting portion 622 may be an annular protrusion arranged around the locking portion 621 , or may be a plurality of protrusions arranged at intervals along the circumference of the locking portion 621 , and this application does not impose any limitation on this.

[0049] In some embodiments, the locking member 620 further includes an elastic portion (not shown), one end of the elastic portion being connected to the first limiting portion 622 and the other end being fixedly connected to the vertical support rod 200. The elastic portion can provide a continuous elastic force to drive the first limiting portion 622 to tightly abut against the inner wall surface of the vertical support rod 200. The connection method between the elastic portion and the vertical support rod 200 includes, but is not limited to, one or more forms such as bonding, welding, clamping, and screwing. Of course, in some embodiments, the locking member 620 may also be provided without an elastic portion. The relative fixation of the locking member 620 and the vertical support rod 200 can be achieved by an interference fit between the locking portion 621 and the fixing hole 200b and / or the positioning hole 611b; or by bonding the limiting portion to the wall of the accommodating cavity 200a.

[0050] It should be noted that the locking member 620 can be an integral structure, in which the locking portion 621, the first limiting portion 622 and the elastic portion are integrally molded. In this example, the elastic portion can be in the form of an elastic arm, an elastic buckle, etc.; of course, the locking member 620 can also be a split structure, which can have two parts, one part molding the locking portion 621 and the first limiting portion 622, and the other part forming the elastic portion, which can be in the form of a spring, a spring sheet, etc.

[0051] In order to facilitate the removal of the locking member 620 from the positioning hole 611b to unlock the fixing member 610 and the vertical support rod 200, please continue to refer to Figure 7In some embodiments, the present application further includes an unlocking member 700. To facilitate installation of the unlocking member 700, the fixing member 610 further includes a positioning portion 612. The positioning portion 612 is connected to the outer wall of the main body 611 and is provided with a fixing groove 612a that communicates with the positioning hole 611b. At least a portion of the unlocking member 700 is installed in the fixing groove 612a and is able to move axially relative to the positioning portion 612. The unlocking member 700 can drive the portion of the locking member 620 located in the fixing groove 612a to retract into the accommodating cavity 200a. When unlocking is required, the user presses to move the unlocking member 700, causing it to contact the locking member 620 and apply a driving force to overcome the friction with the inner wall of the vertical support rod 200 or the elastic force of the elastic portion, thereby retracting it into the accommodating cavity 200a.

[0052] Please refer to Figure 10 In some embodiments, the outer surface of the unlocking member 700 is provided with a hook 730, and the positioning portion 612 is provided with a slot 612b extending in the axial direction. The slot 612b allows the hook 730 to slide. The slot 612b includes a second stop 613 and a third stop 614 spaced apart in the sliding direction. To unlock, the user presses the unlocking member 700, causing it to slide along the slot 612b. During the sliding process, the hook 730 contacts the walls of the slot 612b and is guided to a certain extent. When the hook 730 abuts the third stop 614, the unlocking member 700 can drive the locking member 620 back into the accommodating cavity 200a, and the unlocking member 700 is positioned within the positioning hole 611b. This achieves unlocking while preventing the unlocking member 700 from extending into the accommodating cavity 200a and interfering with the vertical support rod 200. When the locking member 620 is located in the positioning hole 611b, the locking portion 621 drives the unlocking member 700 to move in the opposite direction. The sliding groove 612b is provided with a second limiting portion 613. When the unlocking member 700 is driven by the locking member 620, the hook 730 can abut against the second limiting portion 613, thereby preventing the unlocking member 700 from being separated from the positioning portion 612.

[0053] Please continue reading Figure 10In some embodiments, the unlocking member 700 further includes a base portion 710 and a driving portion 720. The base portion 710 includes an end cover 711 and a cylinder 712. The end cover 711 is connected to one end of the cylinder 712 to form a receiving groove with an opening on one side; the driving portion 720 is connected to the bottom wall of the receiving groove and at least partially extends from the opening to drive the locking member 620; wherein, there is a gap between the inner wall of the cylinder 712 and the driving portion 720, and a hook 730 is provided on the outer wall of the cylinder 712. The gap between the inner wall of the cylinder 712 and the driving part 720 can make the cylinder 712 have a certain deformation ability. With this arrangement, the cylinder 712 can embed the locking member 620 into the fixed groove 612a, and the outer wall surface of the cylinder 712 abuts against the groove wall of the fixed groove 612a, and sliding and limiting are achieved through the fixation of the hook 730 and the slide groove 612b, which can improve the stability of the movement of the unlocking member 700 and protect the unlocking member 700.

[0054] To unlock, the unlocking member 700 is pressed and slid to the appropriate position, causing its driving portion 720 to come into contact with the locking member 620. By applying a driving force, the driving portion 720 overcomes the friction between the locking member 620 and the inner wall of the vertical support rod 200 or the elastic force of the elastic portion, causing it to retract into the accommodating cavity 200a. As the locking member 620 retracts, the unlocking function is achieved.

[0055] Please return to Figure 7 In some embodiments, a plugging head 800 is further included. The plugging head 800 is detachably mounted on the top of the vertical support rod 200 to seal the opening. The plugging head 800 can be cylindrical and have escape holes on both sides. The escape holes can be provided with elastic buckles. The elastic buckles abut against the inner wall of the vertical support rod 200 to secure the plugging head 800 to the top of the vertical support rod 200.

[0056] See also Figure 9 In some embodiments, the fixing member 610 includes a first mounting portion 6111 and a second mounting portion 6112 that are connected and arranged at an angle. A first mounting hole 611a is provided at the corner of the first mounting portion 6111 and the second mounting portion 6112, and a mounting slot 6113 is provided on each of the first mounting portion 6111 and the second mounting portion 6112. The distal end of the transverse brace 100 of the side structure of one adjacent fence frame 10 is rotatably connected to the mounting slot 6113 of the first mounting portion 6111, and the distal end of the transverse brace 100 of the side structure of another adjacent fence frame 10 is rotatably connected to the mounting slot 6113 of the second mounting portion 6112. Exemplarily, the fence frame 10 has four side structures, and the number of upper corner connectors 600 is also four. The extension direction of the first mounting portion 6111 and the extension direction of the third mounting portion are perpendicular.

[0057] The mounting slot 6113 has a first limit position and a second limit position. When the transverse strut 100 is in the first limit position, it is vertical or slightly tilted. When the transverse strut 100 is rotated from the first limit position to the second limit position, it rotates from the vertical or slightly tilted position to the horizontal position. When the fence frame 10 is folded, the two transverse struts 100 are rotated toward the vertical strut 200 and are vertical or slightly tilted. When the fence frame 10 is opened, the two transverse struts 100 are rotated away from the vertical strut 200 and are horizontal.

[0058] See also Figure 11 The lower corner connector 900 includes a first assembly portion 910 and a second assembly portion 920 that are connected and arranged at an angle. An assembly hole 900a is provided at the corner of the first assembly portion 910 and the second assembly portion 920. Both the first assembly portion 910 and the second assembly portion 920 are provided with an assembly groove 900b. The lower end of the vertical strut 200 is inserted into the assembly hole 900a, and the distal end of the diagonal strut 300 of the side structure of one adjacent fence frame 10 is rotatably connected to the assembly groove 900b of the first assembly portion 910. The distal end of the diagonal strut 300 of the side structure of the other adjacent fence frame 10 is rotatably connected to the assembly groove 900b of the second assembly portion 920. Exemplarily, the extension direction of the first mounting portion 6111 is perpendicular to the extension direction of the third mounting portion.

[0059] The assembly slot 900b has a third and fourth limit positions. When the diagonal brace 300 is in the third limit position, it is in a vertical position. When the diagonal brace 300 is rotated from the third limit position to the fourth limit position, it rotates from the vertical position to an inclined position. When the fence frame 10 is folded, the two diagonal braces 300 are rotated toward the vertical brace 200 to assume the vertical position. When the fence frame 10 is opened, the diagonal brace 300 is rotated away from the vertical brace 200 to assume the inclined position.

[0060] See also Figure 12 In some embodiments, the diagonal brace 300 includes a main rod 310 and an assembly 320. One end of the main rod 310 is rotatably connected to the intersection of the two transverse braces 100. The assembly 320 is connected to the end of the main rod 310 away from the transverse braces 100 and is rotatably connected to the lower corner connector 900. The end of the assembly 320 away from the main rod 310 is provided with a curved surface. This facilitates the processing of the diagonal brace 300, and the curved surface allows the diagonal brace 300 to rotate more smoothly and avoid interference.

[0061] The present invention provides a method for folding a fence, comprising the following steps: S01, unlocking the fixing member and the vertical support rod by the locking member, so that the fixing member can slide downward along the vertical support rod; S02. Rotate the transverse strut removed from the upper end of the vertical strut downward, rotate the diagonal strut upward relative to the lower end of the vertical strut, rotate the first connecting rod upward relative to the diagonal strut, and rotate the second connecting rod upward relative to the transverse strut.

[0062] During the folding process, the fabric cover will fold along with the folding of the fence frame. The fence can be folded more conveniently and quickly through the above method.
