A trampoline with high-efficiency cushioning effect

Abstract

The present invention provides a trampoline with a high-efficiency buffering effect, belonging to the technical field of trampolines. The invention comprises: supporting legs; a protective mechanism; and a fixing mechanism. The trampoline with a high-efficiency buffering effect proposed by the invention is based on an existing trampoline, and a buffering mechanism is added that can absorb a certain amount of the downward force generated by a person jumping. The downward force generated by the person jumping is used to circulate air in the buffering mechanism into the protective mechanism, so that the protective cushion in the protective mechanism changes from a vertical state to a horizontal state and expands under the action of the gas. When a person accidentally jumps to the outside of the trampoline, the horizontally expanded protective cushion provides a sufficient foothold for the person, so that the person falls on the protective cushion. At this time, the horizontally expanded protective cushion absorbs the downward force generated by the person, so that the person lands relatively smoothly, thereby achieving good buffering of the downward force when the person jumps out of the trampoline, and providing effective protection for the person.

Description

Technical Field

[0001] The present invention relates to the field of trampolines, and in particular to a trampoline with a high-efficiency buffering effect. Background Art

[0002] A standard trampoline frame is made of metal, measuring 5.05 meters long, 2.91 meters wide, and 1.15 meters high. The net is 4.26 meters long, 2.13 meters wide, and has 112 springs. The surface is made of nylon or a similar material, only six millimeters thick. A large, thick mat sits on each side of the trampoline, providing landing pads for the riders. A jumping area, marked with red lines, measures two meters by one meter. For many years, jumping on a trampoline has been enjoyed as a fun and recreational activity by people of all ages. However, traditionally, it was only used by those who could maintain their balance. Recent research indicates that even minimal trampoline jumping can have significant health benefits, helping to develop balance, aerobic fitness, motor skills, and muscle strength. It can also boost the immune system, improve cell repair, and increase oxygen supply to tissues, among other health benefits.

[0003] However, when teenagers and children are playing on the trampoline, they may fall off the trampoline due to negligence, resulting in various injuries to the teenagers and children. However, existing trampolines cannot effectively alleviate the above situation. Although some trampolines have safety ropes, there is still a possibility that the teenagers and children will hit the vertical poles connected to the safety ropes during the jumping process, causing injuries to the teenagers and children. In addition, there are currently trampolines without safety ropes. Therefore, more attention should be paid to the protection of teenagers and children.

[0004] How to invent a trampoline with efficient cushioning effect to improve these problems has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] In order to make up for the above shortcomings, the present invention provides a trampoline with a high-efficiency cushioning effect, aiming to improve the problem that existing trampolines without safety ropes cannot effectively cushion the impact force of teenagers when they jump out of the trampoline and land on the ground.

[0006] The present invention is achieved in that:

[0007] The present invention provides a trampoline with high-efficiency cushioning effect, comprising:

[0008] The supporting legs are fixedly connected to a fixing frame at the top, and the opposite sides of the supporting legs are fixedly connected to a filling and buffering mechanism, which is used to absorb the downward force generated by jumping and convert it into power for the filling and buffering mechanism;

[0009] A protection mechanism, which is installed at the output end of the charging and buffering mechanism, is arranged between the legs, and gradually opens outward when the charging and buffering mechanism is in operation;

[0010] The fixing mechanism is installed between the supporting leg and the protection mechanism and is used to connect the supporting leg and the protection mechanism.

[0011] By adopting the above technical solution, when a person jumps, the cushioning mechanism absorbs the force generated by the person's jumping, and at the same time, the protective mechanism is inflated, so that the protective mechanism can become horizontal and expand, so that if the person is careless when jumping, the protective mechanism can effectively protect the person. In addition, when the protective mechanism needs to be replaced after long-term use, it can be quickly replaced through the fixing mechanism, which reduces the burden on the person.

[0012] Preferably, a protective ring is installed on the top of the fixed frame, the inner side wall of the fixed frame is fixedly connected to a connecting cloth, the opposite sides of the connecting cloth are slidingly connected to an elastic net, and the outer side wall of the elastic net is fixedly connected to a connecting spring.

[0013] By adopting the above technical solution and setting the protective ring, when a person jumps and lands on the position of the fixed frame, the protective ring can absorb the force generated when the person falls on the fixed frame to a certain extent, preventing the person from directly hitting the hard part of the fixed frame and causing harm to the person, thereby protecting the person. Moreover, by setting the connecting cloth, when the person jumps and lands on the connecting spring, the connecting spring can be prevented from causing further harm to the person, thereby further providing good protection for the person.

[0014] Preferably, the inflation / debuffering mechanism includes an airbag cushion, a push rod, a return spring, an air chamber, an air inlet and a fixing rod; the bottom of the airbag cushion is fixedly connected to the top of the push rod, the middle outer wall of the push rod is slidingly connected to the middle position of the top of the air chamber, the bottom outer wall of the push rod is slidingly connected to the inner wall of the air chamber and fits each other, the return spring is sleeved on the outer wall of the push rod, the top of the return spring is fixedly connected to the bottom of the top of the push rod, the bottom of the return spring is fixedly connected to the top of the air chamber, the air inlet is opened in the middle position of the bottom of the inner wall of the air chamber and passes through the bottom of the air chamber, and one end of the fixing rod is fixedly connected to the bottom position of the outer wall of the air chamber.

[0015] By adopting the above technical solution, the downward force generated by the person's jumping can be absorbed to a certain extent, and the downward force generated by the person's jumping is used to make the charging and buffering mechanism circulate and inflate the protective mechanism, so that the protective pad in the protective mechanism changes from a vertical state to a horizontal state and expands under the action of the gas. When a person jumps to the periphery of the trampoline due to negligence, the horizontally expanded protective pad will provide enough footholds for the person, so that the person falls on the protective pad. At this time, the protective pad in the horizontally expanded state will absorb the downward force generated by the person, so that the person lands more smoothly, thereby achieving good buffering of the downward force when the person jumps out of the trampoline, and providing effective protection for the person.

[0016] Preferably, the protection mechanism includes an inflation tube, a connecting rod, a protective pad and an exhaust hole; one end of the inflation tube is plugged into the middle position of one side of the connecting rod, the side of the connecting rod away from the inflation tube is fixedly connected to one end of the protective pad, the exhaust holes are opened on both sides of the end of the protective pad away from the connecting rod, and the inflation tube is connected to the protective pad.

[0017] By adopting the above technical solution, the protective pad is set to be L-shaped. When a person falls onto the protective pad, the protective pad will bend downward. At this time, under the action of the L-shaped protective pad, the person will not slide to the ground, causing friction on the skin exposed to the environment and causing skin breakage, thereby reducing damage to the person.

[0018] Preferably, the fixing mechanism includes a plug ring, a plug connector, a rotating rod, a knob and a fixing plate; the inner wall of the plug ring fits with the outer wall of the plug connector and slides with each other, the outer wall of the rotating rod is rotatably connected to the plug connector, and the rotating rod passes through the plug connector, the knob is fixedly connected to one end of the rotating rod, the end of the rotating rod away from the knob is fixedly connected to the middle position of the fixing plate, and the side of the fixing plate close to the rotating rod fits with the outer wall of the plug ring.

[0019] By adopting the above technical solution, when the protection mechanism needs to be used for a long time and the protection pad needs to be replaced due to corrosion from sunlight and rain, the knob in the fixing mechanism is turned to rotate the rotating rod, and then the fixing plate can be passed through the plug-in ring. At this time, the inflation tube and the connecting rod that are plugged into each other are separated, and the protection pad in the protection mechanism can be replaced, thereby ensuring that the protection pad has a good protection function, so that the trampoline can provide good protection for people.

[0020] Preferably, the legs are arranged in a circular array along the central axis of the fixed frame, one end of the connecting spring away from the elastic net is fixedly connected to the inner side wall of the fixed frame, and the connecting springs are arranged in a circular array along the central axis of the elastic net.

[0021] Preferably, the fixing rods are arranged in a ring array along the central axis of the air chamber, and one end of the fixing rods away from the air chamber is fixedly connected to the outer side wall of the support leg.

[0022] Preferably, the inflation tubes are arranged in a ring array along the central axis of the fixing frame, the connecting rods are arranged in a ring array along the central axis of the fixing frame, and the connecting rods are arranged between the supporting legs.

[0023] Preferably, one end of the plug ring is fixedly connected to the outer side wall of the leg, and the end of the plug connector is fixedly connected to the end of the connecting rod.

[0024] Preferably, the end of the inflation tube away from the connecting rod is fixedly connected to the outer wall of the air chamber, the inflation tube is communicated with the air chamber, and the inflation tube is installed on the outer wall of the air chamber near the bottom, and the airbag cushion is located in the middle of the bottom of the elastic net.

[0025] The beneficial effects of the present invention are:

[0026] 1. The trampoline with a high-efficiency cushioning effect proposed by the present invention adds a cushioning mechanism that can absorb the downward force generated by people jumping on the basis of the existing trampoline. The cushioning mechanism uses the downward force generated by people jumping to circulate air into the protection mechanism, so that the protective cushion in the protection mechanism changes from a vertical state to a horizontal state and expands under the action of the gas. When a person jumps to the periphery of the trampoline due to negligence, the protective cushion in the horizontal state will provide a sufficient foothold for the person, so that the person falls on the protective cushion. At this time, the protective cushion in the horizontal state will absorb the downward force generated by the person, so that the person lands more smoothly, thereby achieving good cushioning of the downward force when the person jumps out of the trampoline and providing effective protection for the person.

[0027] 2. The trampoline with a highly efficient cushioning effect proposed by the present invention has a protective mechanism that needs to be replaced when the protective pad is corroded by sunlight and rainwater after long-term use. By turning the knob in the fixing mechanism to rotate the rotating rod, the fixing plate can be passed through the plug-in ring. At this time, the inflatable tube and the connecting rod that are plugged into each other are separated, and the protective pad in the protective mechanism can be replaced, thereby ensuring that the protective pad has a good protective function, so that the trampoline can provide good protection for people.

[0038] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0039] Example

[0040] Reference Figure 1-8 , a trampoline with high-efficiency cushioning effect, comprising:

[0041] The support leg 1 has a fixed frame 2 fixedly connected to the top of the support leg 1, and a charging and braking mechanism 7 fixedly connected to the opposite side of the support leg 1. The charging and braking mechanism 7 is used to absorb the downward force generated by jumping and convert it into power for the charging and braking mechanism 7;

[0042] The protection mechanism 8 is installed at the output end of the charging and buffering mechanism 7. The protection mechanism 8 is set between the legs 1, and the protection mechanism 8 gradually opens outward when the charging and buffering mechanism 7 is working;

[0043] The fixing mechanism 9 is installed between the supporting leg 1 and the protection mechanism 8 and is used to connect the supporting leg 1 and the protection mechanism 8.

[0044] It should be noted that, through the arrangement of the above-mentioned structure, when a person jumps, the cushioning mechanism 7 absorbs the force generated by the person's jumping, and at the same time, the protective mechanism 8 is inflated, so that the protective mechanism 8 can become horizontal and expand, so that if the person is careless when jumping, the protective mechanism 8 can effectively protect the person. In addition, when the protective mechanism 8 needs to be replaced after long-term use, the protective mechanism 8 can be quickly replaced through the fixing mechanism 9, thereby reducing the burden on the person.

[0045] Furthermore, a protective ring 3 is installed on the top of the fixed frame 2, the inner wall of the fixed frame 2 is fixedly connected to a connecting cloth 4, the opposite sides of the connecting cloth 4 are slidingly connected to an elastic net 5, and the outer wall of the elastic net 5 is fixedly connected to a connecting spring 6.

[0046] It should be noted that, through the provision of the protective ring 3, when a person jumps and falls on the location of the fixed frame 2, the protective ring 3 can absorb to a certain extent the force generated when the person falls on the fixed frame 2, preventing the person from directly colliding with the hard part of the fixed frame 2 and causing harm to the person, thereby protecting the person. Moreover, through the provision of the connecting cloth 4, when the person jumps and lands on the connecting spring 6, it can prevent the connecting spring 6 from causing further injury to the person, thereby further providing good protection for the person.

[0047] Reference Figure 5 and Figure 8 As a further solution of the present invention, the charging and braking mechanism 7 includes an airbag cushion 71, a push rod 72, a return spring 73, an air chamber 74, an air inlet 75 and a fixing rod 76; the bottom of the airbag cushion 71 is fixedly connected to the top of the push rod 72, the middle outer wall of the push rod 72 is slidingly connected to the middle position of the top of the air chamber 74, the bottom outer wall of the push rod 72 is slidingly connected to the inner wall of the air chamber 74 and fits each other, the return spring 73 is sleeved on the outer wall of the push rod 72, the top of the return spring 73 is fixedly connected to the bottom of the top of the push rod 72, the bottom of the return spring 73 is fixedly connected to the top of the air chamber 74, the air inlet 75 is opened in the middle position of the bottom of the inner wall of the air chamber 74 and passes through the bottom of the air chamber 74, and one end of the fixing rod 76 is fixedly connected to the bottom position of the outer wall of the air chamber 74.

[0048] It should be noted that, through the arrangement of the above-mentioned structure, the downward force generated by the jumping of the person can be absorbed to a certain extent, and the downward force generated by the jumping of the person is used to make the charging and buffering mechanism 7 circulate and inflate into the protective mechanism 8, so that the protective pad 83 in the protective mechanism 8 changes from a vertical state to a horizontal state and expands under the action of the gas. When a person jumps to the periphery of the trampoline due to negligence, the horizontally expanded protective pad 83 will provide the person with enough footholds, so that the person falls on the protective pad 83. At this time, the protective pad 83 in the horizontally expanded state will absorb the downward force generated by the person, so that the person lands more smoothly, thereby achieving a good buffering of the downward force when the person jumps out of the trampoline, and providing effective protection for the person.

[0049] Reference Figure 8 As a further solution of the present invention, the protection mechanism 8 includes an inflation tube 81, a connecting rod 82, a protective pad 83 and an exhaust hole 84; one end of the inflation tube 81 is plugged into the middle position of one side of the connecting rod 82, and the side of the connecting rod 82 away from the inflation tube 81 is fixedly connected to one end of the protective pad 83, and the exhaust holes 84 are opened on both sides of the end of the protective pad 83 away from the connecting rod 82, and the inflation tube 81 is connected to the protective pad 83.

[0050] It should be noted that a one-way valve is provided in the inflation tube 81, so that the gas in the air chamber 74 can only enter the protective pad 83 through the inflation tube 81, and the gas in the protective pad 83 will not re-enter the air chamber 74 through the inflation tube 81. The protective pad 83 is configured to be L-shaped. When a person falls onto the protective pad 83, the protective pad 83 will bend downward. At this time, under the action of the L-shaped protective pad 83, the person will not slide to the ground, causing friction on the skin exposed to the environment and causing skin breakage, thereby reducing damage to the person.

[0051] Furthermore, it should be noted that the initial position of the protective mat 83 is vertical rather than horizontal. On the one hand, this is to prevent inconvenience to people who are climbing onto the trampoline. On the other hand, if the protective mat 83 is initially vertical, it should be in an expanded state. However, the long-term expansion of the protective mat 83 will cause its elasticity to decrease, similar to the elastic force of an elastic spring that is in a stretched state for a long time. Furthermore, if the protective mat 83 is initially horizontal, the trampoline will occupy a large area, causing great inconvenience to people who are walking on it.

[0052] In addition, it should be noted that when a person jumps on the trampoline for a long time and no accidents occur, the inflation mechanism 7 will still inflate air into the protection mechanism 8. Although the protection pad 83 is in a horizontally expanded state, the protection pad 83 will not burst due to the setting of the exhaust hole 84, and the exhaust volume of the exhaust hole 84 is less than the inflation volume of the inflation tube 81.

[0053] Reference Figure 8 As a further solution of the present invention, the fixing mechanism 9 includes a plug ring 91, a plug connector 92, a rotating rod 93, a knob 94 and a fixing plate 95; the inner side wall of the plug ring 91 fits with the outer side wall of the plug connector 92 and slides with each other, the outer side wall of the rotating rod 93 is rotatably connected to the plug connector 92, and the rotating rod 93 passes through the plug connector 92, the knob 94 is fixedly connected to one end of the rotating rod 93, and the end of the rotating rod 93 away from the knob 94 is fixedly connected to the middle position of the fixing plate 95, and the side of the fixing plate 95 close to the rotating rod 93 fits with the outer side wall of the plug ring 91.

[0054] It should be noted that when the protection mechanism 8 needs to be used for a long time and the protection pad 83 needs to be replaced due to corrosion from sunlight and rain, the knob 94 in the fixing mechanism 9 is turned to rotate the rotating rod 93, and then the fixing plate 95 can pass through the plug-in ring 91, and at this time the inflatable tube 81 and the connecting rod 82 that are plugged into each other are separated, and the protection pad 83 in the protection mechanism 8 can be replaced, thereby ensuring that the protection pad 83 has a good protection function, so that the trampoline can provide good protection for personnel.

[0055] On the basis of the above scheme, the legs 1 are arranged in a circular array along the central axis of the fixed frame 2, and the end of the connecting spring 6 away from the elastic net 5 is fixedly connected to the inner wall of the fixed frame 2, and the connecting spring 6 is arranged in a circular array along the central axis of the elastic net 5.

[0056] On the basis of the above solution, the fixing rods 76 are arranged in a circular array along the central axis of the air chamber 74 , and one end of the fixing rods 76 away from the air chamber 74 is fixedly connected to the outer side wall of the support leg 1 .

[0057] On the basis of the above solution, the inflation tubes 81 are arranged in a circular array along the central axis of the fixed frame 2 , the connecting rods 82 are arranged in a circular array along the central axis of the fixed frame 2 , and the connecting rods 82 are arranged between the legs 1 .

[0058] On the basis of the above solution, one end of the plug ring 91 is fixedly connected to the outer side wall of the leg 1 , and the end of the plug connector 92 is fixedly connected to the end of the connecting rod 82 .

[0059] Based on the above scheme, the end of the inflation tube 81 away from the connecting rod 82 is fixedly connected to the outer wall of the air chamber 74, the inflation tube 81 is connected to the air chamber 74, and the inflation tube 81 is installed on the outer wall of the air chamber 74 near the bottom position, and the airbag cushion 71 is located in the bottom middle position of the elastic net 5.

[0060] The working principle of this trampoline with high-efficiency cushioning effect:

[0061] The initial state of the protective pad 83 is vertical. When in use, the legs 1 need to be placed on a stable ground, and then a person can step onto the trampoline and stand on top of the elastic net 5, and then the person can jump;

[0062] When a person jumps on the elastic net 5, the airbag cushion 71 is pressed downward. The elastic net 5, the connecting spring 6 and the airbag cushion 71 absorb the force generated by the jumping. When the airbag cushion 71 is squeezed, the push rod 72 is pressed downward, causing the return spring 73 to compress, further absorbing the downward force. The downward movement of the push rod 72 causes the gas in the air chamber 74 to be input into the protective cushion 83 through the inflation tube 81.

[0063] Reference Figure 1 and Figure 7 When a person jumps away from the elastic net 5, the push rod 72 moves upward under the action of the compressed return spring 73, so that the air chamber 74 draws external air into the air chamber 74 through the air inlet 75, and this process repeats until the protective pad 83 changes from a vertical state to a horizontal expansion state.

[0064] In addition, it should be noted that when the person's initial jumping state deviates, since the height of the person's jump is relatively low, even if they fall outside the trampoline, it will not cause significant harm to the person;

[0065] When the protective pad 83 changes from a vertical state to a horizontally expanded state, the gas in the gas chamber 74 will still enter the protective pad 83 through the inflation tube 81. However, at this time, the excess gas can be discharged through the exhaust hole 84, and the protective pad 83 will not burst. At this time, if a person accidentally jumps outside the trampoline, the horizontally expanded protective pad 83 will provide a sufficient foothold for the person, so that the person falls on the protective pad 83. At this time, the protective pad 83 in the horizontally expanded state will absorb the downward force generated by the person, so that the person lands more smoothly. In addition, since the protective pad 83 is set in an L-shape, the L-shaped protective pad 83 will bend downward when the person falls on the protective pad 83. At this time, under the action of the L-shaped protective pad 83, the person will not slide to the ground, causing the person's exposed skin to rub against the environment and cause skin breakage, thereby reducing the injury to the person.

[0066] When the protective pad 83 is used for a long time and needs to be replaced due to the corrosion of sunlight and rain, the knob 94 in the fixing mechanism 9 is turned to rotate the rotating rod 93, and then the fixing plate 95 can pass through the plug ring 91. At this time, the inflation tube 81 and the connecting rod 82 that are plugged into each other are separated, and the protective pad 83 in the protection mechanism 8 can be replaced, thereby ensuring that the protective pad 83 has a good protective function, so that the trampoline can provide good protection for people.

[0067] After jumping for a while, people can return to the ground from the trampoline. At this time, the gas in the protective mat 83 will be naturally discharged through the exhaust holes 84, so that the protective mat 83 can be changed from a horizontal state to a vertical state again, thereby reducing the floor space of the trampoline.

[0068] It should be noted that the exhaust hole 84 can only discharge the gas in the protective pad 83 to the outside, while the setting of the air inlet hole 75 can only allow external gas to enter the air chamber 74.

[0069] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
