DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that the advantages and features of the present disclosure can be easily understood by those skilled in the art. Hereinafter, it should be noted that the description of these embodiments is used to help understand the present disclosure, but does not constitute a limitation of the present disclosure. In addition, the technical features contained in the various embodiments of the present disclosure described below can be combined with each other as long as they are not mutually inconsistent.

[0022] As shown in Figures 1 to 12, the folding tent of this embodiment has an unfolded state and a folded state, and includes a foldable tent frame body 2, which can be supported independently on the pond surface, and is covered with a cloth cover (not shown) for protection from the sun, wind, rain, etc., and a part of the cloth cover (e.g., an edge part) can be vertically arranged to the side of the tent frame body 2, and this part of the cloth cover is called a surrounding cloth. As shown in Figures 1 and 3 to 5, the tent frame body 2 includes a plurality of leg poles 1 extending in the vertical direction and a canopy connected to the upper part of the leg poles 1, and is supported on the ground via the leg poles 1, and most of the cloth cover covers the canopy. The tent further includes a plurality of eaves poles 3 having inner and outer ends, and the inner ends of the eaves poles 3 are rotatably connected to the leg poles 1, specifically, via pivots. The number and positions of the eaves poles 3 correspond one-to-one to the leg poles 1, that is, the inner end of each eaves pole 3 is rotatably connected to the corresponding leg pole 1, and the above-mentioned surrounding cloth is connected to the outer end of the eaves pole 3, and is supported and opened by the eaves pole 3, so that it can increase the shade area as an awning, and can hang down to the side of the tent as the eaves pole 3 is folded, and can be used as a side surrounding cloth. Each eaves pole 3 has a folded state and an open state, and the outer end of the eaves pole 3 approaches the leg pole 1 when in the folded state, and is shifted a certain distance from the leg pole 1 when in the open state. That is, the eaves pole 3 has a folded state approaching the leg pole 1 and an open state unfolded relative to the leg pole 1. After the eaves pole 3 is unfolded, the surrounding cloth can be spread outward to increase the shade area of ​​the tent. Furthermore, the left eaves pole 3 extends to the left when in the open state, i.e., the outer end of the eaves pole 3 is located to the left of the leg pole 1, and the right eaves pole 3 extends to the right when in the open state, i.e., the outer end of the eaves pole 3 is located to the right of the leg pole 1, thereby supporting and opening the left and right enclosing cloths, increasing the eaves area of ​​the left and right sides of the tent, and increasing the sunshade area on both the left and right sides. When the eaves pole 3 is in the folded state, the enclosing cloth hangs down and is located to the side of the tent.

[0023] The canopy includes a plurality of foldable outer telescopic units 21, which are connected between adjacent leg poles 1. The tent includes a plurality of crossbars 4, which correspond one-to-one in number and position to a plurality of eaves poles 3. As shown in Figs. 7 to 12, each crossbar 4 has a first end rotatably connected to the eaves pole 3 and a second end for detachably connecting to the outer telescopic unit 21. When the eaves pole 3 is in a folded state, the second end of the crossbar 4 is detached from the outer telescopic unit 21, and when the eaves pole 3 is in an open state, the second end of the crossbar 4 is connected to the outer telescopic unit 21. In the process of switching the tent frame body 2 from the unfolded state to the folded state, the second end of the crossbar 4 is detached from the outer telescopic unit 21, and the eaves pole 3 is switched from the open state to the folded state. The second end of the crossbar 4 and the lever of the external telescopic unit 21 use a detachable connection method, and when the external telescopic unit 21 is folded, it can be automatically detached from the external telescopic unit 21 by receiving force from the eaves pole 3. One implementation method is described in detail below.

[0024] In this embodiment, the eaves pole 3 is directly rotatably connected to the leg pole 1 via a pivot, while in some other embodiments, the eaves pole 3 may be indirectly rotatably connected to the leg pole 1 via another member, for example, via a sliding sleeve, a connection cap, etc. on the leg pole 1. The eaves pole 3 may also be detachably connected to the leg pole, for example, by a detachable plug-in connection.

[0025] The outer telescopic unit 21 includes a link 211 that can be rotated downward when the tent frame body 2 is folded, and a slot portion 41 that can be engaged with the link 211 is formed at the second end of the crossbar 4, and the slot portion 41 has a downward slot opening 410 as shown in FIG. 12. The slot formed from the slot portion 41 preferably extends upward from the lower surface of the slot portion 41, and in a cross section perpendicular to the length direction of the link 211 of the slot portion 41, the outline of the slot is approximately an inverted U shape. When the tent frame body 2 is folded, the link 211 rotates downward and disengages from the slot of the slot portion 41, and the connection between the crossbar 4 and the outer telescopic unit 21 is released, which avoids the tent frame body 2 being unable to be folded due to forgetting to fold the eaves pole 3, or the levers of the eaves pole 3 and the tent frame body 2 being damaged. In this embodiment, the eaves poles 3 do not open along the diagonal direction of the tent, but as shown in Figures 3 and 4, each eaves pole 3 extends in the length direction of the first outer telescopic unit 21 (for example, the outer telescopic unit on the front side), that is, in a plan view, the eaves poles 3 are approximately the same as the extension direction of the first outer telescopic unit 21. The crossbar 4 connected to the eaves poles 3 is detachably connected to the second outer telescopic unit 21, and this second outer telescopic unit 21 crosses the first outer telescopic unit 21, for example, the outer telescopic unit on the left side.

[0026] 10b to 12, the link 211 that fits into the crossbar 4 is formed with a positioning bump 211a, and the slot portion 41 has a positioning slot 411 that fits into the positioning bump 211a so that the slot portion 41 restricts the link 211 from sliding in the longitudinal direction. The positioning slot 411 and the slot formed by the slot portion 41 communicate with each other and extend upward from the lower surface of the slot portion 41. In the process of the slot portion 41 engaging with the link 211, the positioning bump 211a enters the positioning slot 411, which has two opposing stopper walls, which are not parallel to the longitudinal direction of the link 211 as a whole, and the positioning bump 211a is located between the two stopper walls, preventing the slot portion 41 from moving the link 211 back and forth. Specifically, the positioning bump 211a comprises a pin, a blind rivet or a rivet fixed to the link 211, and further, the positioning bump 211a is located at a pivotal connection point between the link 211 and another lever (preferably another lever of the eaves frame), and may be a part of a pivot shaft that pivots between the link 211 and another lever, or may be provided on the pivot shaft. In this embodiment, each crossbar 4 is composed of a single rod, but in some other embodiments, the crossbar 4 may be composed of multiple levers.

[0027] The tent further includes a plurality of support rods 5 having a first end and a second end, and the number and positions of the plurality of support rods 5 correspond one-to-one to the eaves poles 3. As shown in FIG. 2b, FIG. 7 to FIG. 12, the first end of each support rod 5 is pivotally connected to the leg pole 1 so as to be rotatable and slidable in the vertical direction, and the second end is pivotally connected to the eaves pole 3. Specifically, the first end of the support rod 5 is pivotally connected to the support base 51, and the support base 51 is connected to the leg pole 1 so as to be slidable in the vertical direction. The support base 51 can preferably be fitted onto the sliding sleeve of the leg pole 1 so as to be slidable in the vertical direction, and the support rod 5 has a lower end pivotally connected to the sliding sleeve and an upper end pivotally connected to the eaves pole 3. An eaves locking mechanism is provided between the support base 51 and the leg pole 1, and when the eaves pole 3 is in an open state, the eaves locking mechanism locks the support base 51 and the leg pole 1. A known structure can be used as the eaves locking mechanism, for example, a movable lock piece (not shown) is provided on the support base 51, a key hole 102 that fits the lock piece is provided on the leg pole 1, and the lock piece is removably inserted into the key hole 102. When in an open state, the lock piece on the support base 51 is inserted into the key hole 102 to lock the eaves pole 3 in an open state and stably unfold it, and when it is necessary to convert to a folded state, the unlock button 52 on the support base 51 is pressed to release the lock piece from the key hole 102, and the support base 51 slides down to the bottom of the leg pole 1, driving the eaves pole 3 to be folded until its outer end and the leg pole 1 approach each other, and at the same time, the first end (lower end) of the support rod 5 also approaches the lower end of the leg pole 1.

[0028] Furthermore, a fixed sheet 30 is provided between the inner end and the outer end of the eaves pole 3, and the fixed sheet 30 is located at approximately the center position of the eaves pole 3. A first end of the crossbar 4 is rotatably connected to the fixed sheet 30 via a first pivot 301, and a second end (upper end) of the support rod 5 is rotatably connected to the fixed sheet 30 via a second pivot 302. When the eaves pole 3 is in the folded state, the angle between the axis of the first pivot 301 and / or the second pivot 302 and the horizontal plane is less than 10 degrees. Specifically, when the eaves pole 3 is in the folded state, the axis of the first pivot 301 and the axis of the second pivot 302 are preferably parallel to the horizontal plane or inclined at only a small angle, and the axis of the pivot connecting the eaves pole 3 and the leg pole 1 is also preferably parallel to the horizontal plane or inclined at only a small angle, so that the eaves pole 3 and the crossbar 4 can automatically drop under the action of their own gravity and hang down beside the leg pole 1. Furthermore, when the eaves pole 3 is in the folded state, the support rod 5 approaches the front or rear side of the eaves pole 3, and when viewed from the front or rear side, the support rod 5 is completely hidden by the eaves pole 3.

[0029] As shown in Fig. 2b and Fig. 7 to Fig. 9, the leg pole 1 includes a leg pole main body 10 extending in the vertical direction, a fixed joint 11 fixed to the upper end of the leg pole main body 10, and a foot pad 12 fixed to the lower end of the leg pole main body 10, and the inner end of the eaves pole 3 is pivotally connected to the fixed joint 11, the support base 51 is slidably fitted to the leg pole main body 10, and a key hole 102 is drilled in the leg pole main body 10. The foot pad 12 is provided with a relatively large contact area that contacts the ground, and the foot pads 12 of some of the leg poles 1 (e.g., the two leg poles 1 on the right side) are provided with rollers 13 for transporting the tent. Unless otherwise specified, the "upper end of the leg pole 1" and the "lower end of the leg pole 1" below refer to the fixed joint 11 and the foot pad 12, respectively. Furthermore, some or all of the foot pads 12 are provided with sockets, and after the tent is folded, a protective bag with an open bottom end can cover the tent, and the bottom end of the protective bag is fixed to the sockets by a connection assembly, for example, by inserting a plug on a connection tape into the socket of the foot pad 12 to fix the protective bag to the tent.

[0030] As shown in Figures 1, 3 to 5, the canopy of this embodiment includes a plurality of foldable outer telescopic units 21 and a plurality of foldable inner telescopic units 22. The outer telescopic units 21 are connected between adjacent leg poles 1, and the number of leg poles 1 is four, so that one outer telescopic unit 21 is provided on each of the four sides of the tent, i.e., the front, rear, left and right. Each outer telescopic unit 21 includes at least one link assembly 210 rotatably connected between adjacent leg poles 1, and each link assembly 210 includes two links 211 that can be deployed or moved toward each other, and the middle parts of the two links 211 are rotatably connected via a third pivot 212, forming a cross-shaped sandwich structure. The upper end of the leg pole 1 (specifically, the fixed joint 11) is pivotally connected to one end of one link 211 of the link assembly 210 adjacent thereto, and the leg pole 1 (specifically, the leg pole main body 10) is further provided with a sliding sleeve 101, which is fitted on the leg pole 1 so as to be slidable in the up-down direction, and which is pivotally connected to one end of the other link 211 of the link assembly 210. When folded, the sliding sleeve 101 slides downward, and the two links 211 of the link assembly 210 approach each other in the lateral direction, bringing the leg poles 1 closer to each other, and reducing the size of the tent in the front-rear and left-right directions, as shown in FIG. 6. Specifically, in this embodiment, each external telescopic unit is composed of three link assemblies 210 which are connected to be rotatable in sequence. The above-mentioned slot portion 41 is preferably detachably connected to the upper end of a link 211 to which the upper end of the leg pole 1 is connected, and the above-mentioned positioning bump 211a is also formed on the upper end of the link 211.

[0031] Each of the inner telescopic units 22 includes a first push rod 222 and a third push rod 221, one end of which is rotatably connected to each other, and the other end of the third push rod 221 is rotatably connected to the upper end of the leg pole 1, and the other end of the first push rod 222 of each inner telescopic unit 22 is rotatably connected to the center lock 23. The center lock 23 includes a top cap 231 and a bottom cap 232 that can be engaged or disengaged with each other, and the other end of the first push rod 222 is rotatably connected to the top cap 231, and each inner telescopic unit 22 includes a second push rod 223, one end of which is rotatably connected to the first push rod 222, and the other end of which is rotatably connected to the bottom cap 232. Each inner telescopic unit 22 is provided with a tilt rod 224, and the upper end of the tilt rod 224 is rotatably connected to the third push rod 221, and the lower end is rotatably connected to the sliding sleeve 101 of the leg pole 1. After the top cap 231 and the bottom cap 232 are engaged, the tent frame body 2 is locked in an unfolded state by the center lock 23, and after the top cap 231 and the bottom cap 232 are disengaged, the inclined rod 224 moves downward together with the sliding sleeve 101, driving the internal telescopic unit 22 to fold, that is, the third push rod 221 and the first push rod 222 rotate downward, so that the inner end of the third push rod 221 and the outer end of the first push rod 222 approach the lower end of the leg pole 1, the upper ends of the top cap 231 and the leg pole 1 approach each other, and the lower end of the second push rod 223 and the bottom cap 232 and the outer end of the first push rod 222 approach each other.

[0032] The tent frame main body 2 further includes a reinforcing rod unit 6 connected between the outer telescopic unit 21 and the center lock 23. Specifically, the reinforcing rod unit 6 includes a third reinforcing rod 621 and a first reinforcing rod 622, one end of which is rotatably connected, and the other end of the third reinforcing rod 621 is rotatably connected to the outer telescopic unit, and the other end of the third reinforcing rod 621 is rotatably connected to the center lock 23, specifically, the top cap 231. The reinforcing rod unit 6 further includes a second reinforcing rod 623, one end of which is rotatably connected to the first reinforcing rod 622, and the other end of which is rotatably connected to the bottom cap 232. In this embodiment, the other end of the third reinforcing rod 621 is rotatably connected to the cross-connection point of the central link assembly 210. Specifically, the other end of the third reinforcing rod 621 is rotatably connected to a pivot seat 624 via a fourth pivot 621a, and the pivot seat 624 is fixedly connected to the third pivot 212, and the axis of the fourth pivot 621a and the axis of the third pivot 212 form an angle greater than 0 and less than 180 degrees, and are preferably perpendicular to each other. The tent of this embodiment has two reinforcing rod units 6, which are provided on the left and right sides of the canopy, respectively.

[0033] Further, in this embodiment, the inner end of each inner telescopic unit 22 and the inner end of the reinforcing rod unit 6 are rotatably connected to the center lock 23 via a connecting mechanism 7, and the connecting mechanism 7 includes a hook pin 70 and a connector (specifically, the upper connector 71 and the lower connector 72 described below) that fit together, and a hook pin groove for accommodating the hook pin 70 is formed in the connector, and the hook pin groove has a slot opening 702 into which the hook pin 71 enters, and the slot opening 702 is arranged to allow the hook pin 70 to enter the hook pin groove in a direction intersecting with its center line. In other words, unlike the conventional screw connection method (where the screw is inserted into the screw hole of the lever roughly along its center line), in this embodiment the hook pin 70 enters the hook pin groove in the connector from the circumferential outside of the connector. Specifically, as shown in Figures 13 to 16b, the connector is a hook-shaped member roughly like a hook, and the hook pin 70 is hooked onto the connector. The top cap 231 and the bottom cap 232 of the center lock 23 each have a plurality of protruding connection parts 233 spaced apart in the circumferential direction, and the top cap 231 and the bottom cap 232 are roughly petal-shaped. A hook pin 70 is formed on the opposing surfaces of two adjacent connection parts 233, and a connector is located between the two adjacent connection parts 233, and each connector and the two hook pins 70 are connected and engaged with each other. The connector comprises a plug body 700 connected to or integrally formed with the inner end of the internal telescopic unit 22 or the reinforcing rod unit 6, and a hook portion 701 that extends by bending. The plug body 700 is specifically inserted into the end of the lever (e.g., the inner end of the first reinforcing rod 622, the inner end of the second reinforcing rod 623, the inner end of the first push rod 222, or the inner end of the second push rod 223) and fastened and connected by a screw. One end of the hook portion 701 and the plug body 700 are fixedly connected or integrally formed, and the space between the hook portion 701 and the plug body 700 is the above-mentioned hook pin groove. A slot opening 702 through which the hook pin 70 enters the hook portion 701 is formed between the other end of the hook portion 701 and the plug body 700.A connecting rib 703 is connected between the other end of the hook portion 701 and the plug body 700, and one slot opening 702 is formed on each of the opposing sides of the connecting rib 703 so that two hanging pins 70 can be inserted therein. The width of the connecting rib 703 is smaller than the distance between a pair of adjacent hanging pins 70, and therefore passes between these two hanging pins 70.

[0034] A hook pin 70 is provided on each of the top cap 231 and the bottom cap 232, and the connector includes an upper connector 71 of the hook pin 70 hooked on the top cap 231, and a lower connector 72 of the hook pin 70 hooked on the bottom cap 232. Both the upper connector 71 and the lower connector 72 have the plug body 700, the hook portion 701, and the slot opening 702 described above, but the difference is simply that the inner wall of the hook portion 701 is slightly different. As shown in Figures 14 and 16a, the slot opening 702 of the upper connector 71 faces upward, and the hook portion 701 of the upper connector 71 has a first inclined inner wall 71a facing the plug body 700, and the first inclined inner wall 71a faces the surface of the plug body 700 and is parallel to each other. 4 and 16b, the slot opening 702 of the lower connector 72 faces upward, the hook portion 701 of the lower connector 72 has a second inclined inner wall 72a facing the plug body 700 and a stopper inner wall 72b facing the hook pin 70 therein, the stopper inner wall 72b is located between the second inclined inner wall 72a and the slot opening 702, the stopper wall is above the hook pin 70 and faces directly to the hook pin 70, specifically, one side of the stopper wall close to the slot opening 702 is lower than one side close to the second inclined inner wall 72a, so that the hook pin 70 slides out from the slot opening 702 of the lower connector 72 during the process of flipping or folding the lever. The hook pin 70 is specifically molded integrally with the top cap 231 and the bottom cap 232.

[0035] Specifically, the inner end of the first push rod 222 of each inner telescopic unit 22 is fixedly provided with one upper connector 71, and the upper connector 71 is hooked to the hook pin 70 of the top cap 231 to be rotatably connected to the top cap 231, and the inner end of the second push rod 223 of each inner telescopic unit 22 is fixedly provided with one lower connector 72, and the lower connector 72 is hooked to the hook pin 70 of the bottom cap 232 to be rotatably connected to the bottom cap 232. The inner end of the first reinforcing rod 622 of each reinforcing rod unit 6 is fixedly provided with one upper connector 71, and the upper connector 71 is hooked to the hook pin 70 of the top cap 231 to be rotatably connected to the top cap 231, and the inner end of the second reinforcing rod 623 of each reinforcing rod unit 6 is fixedly provided with one lower connector 72, and the lower connector 72 is hooked to the hook pin 70 of the bottom cap 232 to be rotatably connected to the bottom cap 232. In particular, the hook pin 70 slides into the connector through the slot opening 702, and then the lever is pulled downward, causing the hook pin 70 to enter the inside of the connector. Due to the weight of the lever and the action of other levers, the connector remains hooked onto the hook pin 70, ensuring effective connections between the internal telescopic unit 22 and the center lock 23, and between the reinforcing rod unit 6 and the center lock 23, and will not come loose during normal use. Compared to conventional screw connection methods, assembly is easier and costs are lower.

[0036] In the tent shown in Figures 1, 2 to 4, the reinforcing rod units 6 are provided only between the outer telescopic units 21 on the left and right sides and the center lock 23. On the other hand, in the tent shown in Figures 17 to 18, the reinforcing rod units 6 are provided between each outer telescopic unit 21 and the center lock 23, the first reinforcing rods 622 of each reinforcing rod unit 6 are connected to the top caps 231 of the center lock 23 via their respective connecting mechanisms, the second reinforcing rods 623 of each reinforcing rod unit 6 are connected to the bottom caps 232 of the center lock 23 via their respective connecting mechanisms, the first push rods 222 of each inner telescopic unit 22 are connected to the top caps 231 of the center lock 23 via their respective connecting mechanisms, and the second push rods 223 of each inner telescopic unit 22 are connected to the bottom caps 232 of the center lock 23 via their respective connecting mechanisms.

[0037] The tent is used as follows: The tent frame body 2 is unfolded, and after unfolding, the top cap 231 and the bottom cap 232 are engaged with each other to stably unfold the tent, as shown in FIG. 1, the eaves pole 3 on one side can be opened as shown in FIG. 3, or the eaves poles 3 on both sides can be opened as shown in FIG. 4 and FIG. 5 according to the needs. The specific process of unfolding the eaves pole 3 is as follows: The eaves pole 3 is lifted, the support base 51 moves upward accordingly, and the second end of the crossbar 4 engages with the positioning bump 211a of the link 211, the eaves locking mechanism is locked, and the eaves pole 3 is stably in its open state. The specific process of folding the eaves pole 3 is as follows: The eaves locking mechanism is unlocked, and the second end of the crossbar 4 is released from the link 211, and the support base 51 slides downward under the action of gravity, and the eaves pole 3 and the crossbar 4 hang down automatically to the side of the leg pole main body 10. When folding the tent, the eaves pole 3 can be folded in advance. If the folding is forgotten, during the folding process of the tent frame body 2, the crossbar 4 can be automatically released from the link 211 due to the pressing action of an external force, specifically, the top cap 231 and the bottom cap 232 are unlocked, the sliding sleeve 101 in the leg pole main body 10 moves downward, and the links 211 of the external telescopic unit 21 rotate toward each other, in particular the link 211 connected to the crossbar 4 rotates downward and comes out of the slot opening 410 in the slot portion 41, and the tent frame body 2 is folded normally.

[0038] After the tent is unfolded, the eaves pole 3 can be flexibly selected to be opened or stowed according to the needs, and the opening and stowage are quick and convenient. The crossbar 4 can reinforce the eaves pole 3 after it is opened, and has good strength. In particular, if the eaves pole 3 is forgotten to be stowed when folding the tent, the second end of the crossbar 4 can be automatically detached from the link 211 of the outer telescopic unit 21 by the action of external force as the outer telescopic unit 21 is folded, so that the eaves pole 3 will not be accidentally broken or the structure of the tent frame body 2 will not be destroyed due to forgetting to stow the eaves pole 3. In addition, if a foldable reinforcing rod unit 6 is provided between the outer telescopic unit 21 and the center lock mechanism 23, the thrust of the outer telescopic unit 21 caused by the crossbar 4 can be offset or reduced at the same time as the tent frame body 2 is unfolded and folded, and the problem of the outer telescopic unit 21 being deformed into a recess due to the thrust of the crossbar 4 can be avoided. The tent frame body 2 can be opened and stowed by locking with the center lock 23.
