Description

Technical Field

[0001] The present invention relates to the technical field of sports equipment, and in particular to a method for quickly storing a foldable trampoline. Background Art

[0002] Trampolines are becoming increasingly popular as a recreational sport. They are widely used in homes and amusement parks, but existing trampolines are complex to install and difficult to store. Some trampolines only partially fold, especially those with nets. Due to their large size, they cannot be folded, requiring repeated disassembly and assembly, which is time-consuming and labor-intensive.

[0003] At the same time, when the trampoline frame and the jumping cloth are folded as a whole, the spring between the frame and the jumping cloth will pre-tighten the frame, which may easily cause harm to people during folding. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a method for quickly storing a foldable trampoline.

[0005] The present invention provides a method for quickly storing a trampoline, comprising the following steps:

[0006] S1. Storage of fence:

[0007] Remove the seine and fold it for storage;

[0008] S2, guardrail folding:

[0009] Pull the outer sleeve at the bottom of the guardrail rod to rotate the guardrail rod toward the jumping cloth until it rotates to the upper surface of the jumping cloth;

[0010] S3, releasing the pre-tightening force of the trampoline frame;

[0011] Lift the release frame on the short frame on one side of the trampoline frame, and simultaneously lift the side of the trampoline cloth connected to the release frame. The release frame and the springs of the other short frame of the trampoline frame opposite to the release frame return to their natural lengths, and the preload force of the springs is released.

[0012] S4, Leg folding:

[0013] Unlock the legs and rotate and fold the legs toward the middle of the trampoline frame until they reach the bottom of the trampoline frame;

[0052] The terms "first," "second," and "third" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," or "third" may explicitly or implicitly include one or more of such features.

[0053] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0054] As attached Figure 1-4 As shown, the rapid storage method of the trampoline of the present invention is applicable to the trampoline having the following structure:

[0055] First, the guardrail of this embodiment includes:

[0056] A guardrail body 10, wherein a folding portion 11 extends downward from the bottom of the guardrail body 10;

[0057] A fixing seat 21 is fixed on the trampoline frame 20, and a docking portion 211 is provided above the fixing seat 21;

[0058] in,

[0059] Two opposing clamping portions 212 are provided at the top of the docking portion 211, and a receiving groove 213 that can accommodate the folding portion 11 is formed in the middle of the two clamping portions 212. The folding portion 11 is connected to the clamping portion 212 by a connecting shaft 214, and the folding portion 11 rotates in the receiving groove 213 with the connecting shaft 214 as the rotating shaft. A locking piece 12 is provided on the outside of the folding portion 11 and the docking portion 211. When the folding portion 11 is erected, the locking piece 12 limits the rotation of the folding piece 11; when the folding portion 11 is horizontally arranged, the guardrail rod body 10 is in a folded state, and the locking piece 12 limits the rotation of the folding piece 11.

[0060] like Figure 2 As shown, the locking member 12 includes

[0061] The outer sleeve 121 is sleeved on the outside of the folding portion 11 and the docking portion 211;

[0062] The spring 122, which is a compression spring in this embodiment, is located inside the outer sleeve 121 and is sleeved on the outside of the folding portion 11 and the docking portion 211.

[0063] like Figure 4 As shown, the bottom of the outer sleeve 121 is provided with an annular limiting portion 1211 extending inwardly; when the guardrail is folded, the outer sleeve 121 is pulled upward to the top of the clamping portion 212, and the limiting effect of the outer sleeve 121 on the folding portion 11 and the docking portion 211 disappears. The folding portion 11 is rotated toward the side opening of the accommodating groove 213 to be placed horizontally, and the outer sleeve 121 is released. The spring 122 is in a compressed state, and the annular limiting portion 1211 is pressed by the spring 122 and rests on the fixing seat 21. , the guardrail is folded and locked; when the guardrail is in use, the guardrail rod body 10 is pulled to rotate in the opposite direction to the erected state, and the spring 122 returns to its initial state. Since the spring 122 in this embodiment is a compression spring, the annular limiting portion 1211 is subjected to the downward pressure of the spring 122, so that the outer sleeve 121 is located on the outside of the folding portion 11 and the docking portion 211, and the connecting shaft 214 is located in the outer sleeve 121, so that the folding portion 11 is in a vertical state, ensuring that the guardrail rod body 10 will not fall over after being erected.

[0064] like Figure 2 As shown, the outer diameter of the folding portion 11 is smaller than the outer diameter of the guardrail body 10, and a limiting ring 111 is also provided on the folding portion 11. The spring 122 is located between the limiting ring 111 and the annular limiting portion 1211 of the outer sleeve 121. The annular limiting portion 1211 is subjected to the pressure of the spring 122, so the outer sleeve 121 is always under the pressure of the spring 122 and does not require additional force.

[0065] Continue to see Figure 2 A plug-in plate 112 is provided at the bottom of the folding portion 11, and a through hole 113 is opened on the plug-in plate 112. Second through holes 2121 are provided at corresponding positions of the two clamping portions 212. The plug-in plate 112 is arranged in the accommodating groove 213. The connecting shaft 214 passes through the second through hole 2121 of the clamping portion 212 on one side, the through hole 113 of the plug-in plate 112, and the second through hole 2121 of the clamping portion 212 on the other side. The folding portion 11 can rotate in the accommodating groove 213.

[0066] The accommodating groove 213 includes an upper opening 2131 and at least one side opening 2132. In this embodiment, the accommodating groove 213 has two side openings 2132, one side opening 2132 is arranged close to the inner side of the trampoline frame 20, and the other side opening 2132 is arranged close to the outer side of the trampoline frame 20, so that when the guardrail bar body 10 is folded, it rotates from the upper opening 2131 of the accommodating groove 213 to the side opening 2132 located on the inner side. The folded guardrail bar body 10 is located on the inner side of the trampoline frame 20 and does not occupy additional space.

[0067] The inner diameter of the outer sleeve 121 is matched with the outer diameter of the limiting ring 111 so that the outer sleeve 121 can move up and down. During this process, the outer sleeve 121 is always under the pressure of the spring 122.

[0068] Secondly, in order to prevent the trampoline's jumping cloth from rebounding, the trampoline installation needs to have a certain pre-tightening force. Since there are multiple springs in a trampoline, the frame is always in a tightening state. When folding under pre-tightening force, the frame will fold quickly during the folding process, causing people to lose control and injure others. Therefore, the trampoline frame of this embodiment, as shown in the attached Figure 5-Figure 7 Shown, including:

[0069] The trampoline frame 20 is a rectangular frame structure formed by two long frames 22 and two short frames 23, with a storage space formed inside. The long frames 22 are foldable.

[0070] The edge of the jumping cloth 30 is fixed to the frame by a spring 50;

[0071] A release mechanism is provided on the short frame 23 on one side, which can release the pre-tightening force generated by the spring 50 on the trampoline frame 20. The release mechanism includes:

[0072] The release frame 24 is a U-shaped frame structure, which is disposed above a short frame 23 and a portion of the two long frames 22 of the trampoline frame 20. The ends of the release frame 24 are hinged to the two long frames 22 of the trampoline frame 20 so that the release frame 24 can rotate about a hinge point 27.

[0073] There are two telescopic cylinders 25, which are symmetrically arranged on both sides of the release frame 24. The telescopic cylinders 25 tilt when extended. They include a cylinder barrel and a piston rod. The cylinder barrel is fixed on the inner side of the long frame 22 of the trampoline frame 20, and the piston rod is fixed to the bottom end of the release frame 24. The telescopic cylinders 25 are used to control the rotation rate of the release frame 24;

[0074] One end of the spring 50 located at the release frame 24 is connected to the trampoline cloth 30, and the other end is connected to the release frame 24, and the remaining elastic parts are connected to the trampoline frame 20; when the trampoline frame 20 is lifted upward around the hinge point 26, the telescopic cylinder 25 controls the release frame 24 to slowly lift up at a certain rate to avoid injury. The trampoline cloth 30 is bent to a certain extent, and the spring 50 returns to its natural length. The pre-tightening force of the spring 50 on the trampoline frame 20 disappears, and then the long frame 22 of the trampoline frame 20 is folded in half.

[0075] In this embodiment, when the trampoline frame is folded, the release frame 24 can release the preload force generated by the spring 50. At the same time, the setting of the telescopic cylinder 25 can control the rotation speed of the release frame 24, which saves time and effort, improves the safety of the trampoline frame folding, and avoids harm to the user.

[0076] like Figure 7 As shown, the release frame 24 includes a first link 241, a second link 242, and a third link 243. The first link 241 is parallel to the third link 243, the second link 242 is perpendicular to the first link 241 and the third link 243, and the second link 242 connects the ends of the first link 241 and the third link 243 close to the short side 23. The second link 242 is arranged above the short side 23 of the trampoline frame 20, and the first link 241 and the third link 243 are respectively arranged above the two long sides 22 of the trampoline frame 20.

[0077] During the use of the trampoline, in order to ensure the firmness of the connection between the release frame 24 and the trampoline frame 20 and improve safety, a locking mechanism is provided on the short frame 23 of the trampoline frame 20. Figures 8-10 As shown, the locking mechanism 26 includes:

[0078] The fixing member 261 has an inverted U-shaped structure in this embodiment and includes a first fixing plate 2611 and a second fixing plate 2612 arranged vertically and parallel to each other. The top ends of the first fixing plate 2611 and the second fixing plate 2612 are connected by a connecting cross plate 2613, which is fixed to the bottom of the short frame 23 by bolts. The first fixing plate 2611 has a fixing hole 2614, and the second fixing plate 2612 has a guide hole 2615.

[0079] A connecting rod 262, one end of which is fixed to the first fixing plate 2611, and the other end of which is provided with a locking tongue 263, which can slide back and forth along the connecting rod 262;

[0080] The locking compression spring 264 is passed through the connecting rod 262, one end of which is a movable end and the other end is fixed to the locking tongue 263; under the outward elastic pressure of the locking compression spring 264, the locking tongue 263 can pass through the guide hole 2615 on the second fixing plate 2612.

[0081] In order to make the locking and contact locking of the release frame 24 and the trampoline frame 20 easy to operate, as Figure 7 As shown, a rotating locking plate 2421 of a rectangular plate structure is provided on the inner side of the second connecting rod 242. The rotating locking plate 2421 extends downward perpendicular to the second connecting rod 242. A rectangular locking hole 2422 is opened on the rotating locking plate 2421, and the locking tongue 263 passes through the locking hole 2422 to lock the release frame 24.

[0082] In this embodiment, the upright projection of the locking tongue 263 is shaped like a right-angled trapezoid. A horizontal guide groove (not shown) extending inwardly along its length is defined at one end of the locking tongue 263, adjacent to the locking compression spring 264. When the locking tongue 263 moves, the other end of the connecting rod 262 slides within the guide groove. A downwardly extending, inclined guide surface 2631 is provided at one end of the locking tongue 263, adjacent to the second fixing plate 2612. When the rotating locking plate 2421 moves downward, the guide surface 2631 is subjected to downward pressure, causing the locking tongue 263 to move backward along the connecting rod 262. When the rotating locking plate 2421 moves into contact with the locking tongue 263 in the locking hole 2422, the locking tongue 263 is no longer subjected to pressure. Under the thrust of the locking compression spring 264, the locking tongue 263 extends out of the locking hole 2422, locking the release frame 24 with the short frame 23 of the trampoline frame 20.

[0083] Continue to see Figure 8 A handle 2632 is also provided at one end of the lock tongue 263 close to the locking compression spring 264. In this embodiment, the handle 2632 is a plate-like structure extending horizontally on both sides with the rear end of the lock tongue 263 facing parallel to the first fixed plate 2611. When the handle 2632 is pushed toward the first fixed plate 2611, the locking compression spring 264 is compressed, the lock tongue 263 disengages from the locking hole 2422, and the release frame 24 rotates upward. The telescopic cylinder 25 controls the rotation rate of the release frame 25.

[0084] In this embodiment, the legs 40 are connected to the trampoline frame 20 via a locking and folding mechanism 60;

[0085] Among them, such as Figure 11 As shown, the locking and folding mechanism 60 includes:

[0086] The first connecting member 61 is fixed to the bottom of the trampoline frame 20 to form an open receiving space 611;

[0087] The locking safety member is rotatably arranged in the accommodation space 611, including

[0088] The lock catch 62 is rotatably fixed in the accommodating space 611. A first connecting portion 621 is extended outward from one end of the lock catch 62. A spring 63 is provided between the first connecting portion 621 and the interior of the first connecting member 61. A locking hook portion 622 is provided at one end of the lock catch 62 opposite the first connecting portion 621. A pressing portion 623 is further provided below the first connecting portion 621.

[0089] The locking ring 41 is fixed to one side above the support leg 40, the locking hook portion 622 cooperates with the locking ring 41, the spring 63 is extended, and the locking hook portion 622 is pulled upward by the spring 63. At this time, the support leg 40 is tilted under the action of the tension, and the lock buckle 621, the support leg 40 and the top plate of the first connecting member 61 form a triangular support structure. The support leg 40 is tilted and locked to support the trampoline frame 20; the pressing portion 623 is pressed down, the locking hook portion 622 rotates out of the locking ring 41, and the support leg 40 rotates and folds to the other side.

[0090] The legs 40 of this embodiment are easy to fold. When the trampoline is in use, the locking safety member 60 can prevent the potential danger caused by the rebound of the legs 40. After folding, the legs 40 are not subjected to stress, ensuring safe folding and easy storage, thus solving the problem of large space occupation and difficult storage after the user returns home.

[0091] The first connecting member 61 is an inverted U-shaped structure. Both sides of the first connecting member 61 are parallel to the length direction of the trampoline frame 20. When the legs 40 are folded, they rotate toward the inner side of the trampoline away from the short frame 23 of the trampoline frame 20.

[0092] like Figure 12 As shown, a connecting plate 612 is obliquely provided in the accommodating space 611 of the first connecting member 61 , a second connecting portion 6121 extends from the upper end of the connecting plate 612 , and the first connecting portion 621 and the second connecting portion 6121 are connected via a spring 63 .

[0093] A through hole 624 is formed in the middle of the lock buckle 62 , and first mounting holes 613 are provided at corresponding positions on both sides of the first connecting member 61 . The lock buckle 62 is mounted inside the first connecting member 61 through a first rotating shaft 64 , and the lock buckle 62 can rotate around the first rotating shaft 64 .

[0094] The locking hook portion 622 is a "C"-shaped structure. The locking hook portion 622 hooks the locking ring 41. After the leg 40 is tilted to one side and locked, the lock buckle 621, the leg 40 and the top plate of the first connecting member 61 form a triangular support structure. The locking hook portion 622 is separated from the locking ring 41, and the leg 40 rotates in the opposite direction to the bottom of the trampoline frame to complete the folding of the leg. Figure 13 shown.

[0095] In this embodiment, the leg 40 is a U-shaped structure with a width equal to the width of the trampoline frame 20. The two endpoints of the leg 40 span the width of the trampoline and are connected to the two long sides of the trampoline frame 20. Specifically, a pivoting connector 42 is provided at the endpoint of the leg 40. The pivoting connector 42 has a second through hole 43 formed therein. Second mounting holes 614 are also provided on both sides of the first connecting member 61. The leg 40 is mounted to the first connecting member 61 via a second rotating shaft 65.

[0096] The above-mentioned method for quickly storing the trampoline includes the following steps:

[0097] S1. Storage of fence:

[0098] Remove the seine and fold it for storage;

[0099] S2, guardrail folding:

[0100] When the outer sleeve 12 is pulled upward to move above the clamping portion 212, the outer sleeve 12 is always located at the outer side of the folding portion 11 and the docking portion 211 under the downward pressure of the spring 122, and the connecting shaft 214 is located in the outer sleeve 121, so that the folding portion 11 is in a vertical state, ensuring that the guardrail body 10 will not fall after it is erected;

[0101] S3, releasing the pre-tightening force of the trampoline frame;

[0102] First, push the handle 2632 toward the first fixing plate 2611, the locking compression spring 264 is compressed, the locking tongue 263 disengages from the locking hole 2422, and the release frame 24 is lifted upward, releasing the spring preload. After letting go, the locking tongue 263 automatically rebounds to its original position. Since the spring has a preload in the initial state, the trampoline of this embodiment will have a pulling force of about 700N at the moment the release frame 24 is lifted, which will instantly pull up the release frame 24. At this time, the two telescopic cylinders 25 can slow down the rebound speed. The pulling force of the telescopic cylinder 25 is 200N, which can offset part of the pulling force. In this way, the movement speed of the release frame 24 can be slowed down until the preload on the short frame 23 and the release frame 24 is released and the piston rod of the telescopic cylinder 25 reaches its maximum position.

[0103] S4, Leg folding:

[0104] By manually pressing the pressing portion 623 of the lock buckle, the C-shaped opening of the lock hook portion 622 disengages the locking ring 41, and the spring 63 is in a natural state. The legs 40 rotate in the opposite direction until they are rotated to the bottom of the trampoline frame 20, completing the folding of the legs. After folding, the legs 40 are no longer subjected to force, thus avoiding potential safety risks.

[0105] S5. Fold the trampoline frame in half:

[0106] A rotating hinge is provided in the middle of the long frame 22. The rotating joint includes two hinged rotating members 221. The side of the rotating member 221 is an inverted U-shaped structure with a wide top and a narrow bottom. The hinge point is located at the bottom. The two midpoint ends of the long frame 22 are respectively fixed inside the two rotating members 221. When the trampoline frame 20 is placed horizontally, the two rotating members are opened downward.

[0107] When folding, the long frame 22 of the trampoline frame 20 is folded in half, and one of the rotating parts 221 rotates downward around the hinge point. After folding, the legs 40 are located on the inner side and the guardrails are located on the outer side. Figure 15 shown.

[0108] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
