This patent application claims the benefit and priority of Chinese Patent Application No. 202311321684.0 filed with the China National Intellectual Property Administration on Oct. 12, 2023, the disclosure of which is incorporated by reference herein in its entirety as part of the present application.
The present disclosure belongs to the field of sports equipment, relates to an instrument for bouncing, in particular to a trampoline and an elastic system.
The trampoline, as sports and entertainment equipment, is loved by people, especially children and young people. However, the trampoline is too soft to stand firm, and is not suitable for middle-aged and elderly people. The cantilever springboard for diving is easy to stand firm, but is too huge and complex for indoor jumping. In the Chinese patent with the publication number of CN102553128A, a spring-supported rigid plate, as a jumping exerciser, is limited by the linear characteristics of compression springs and can affect the sense of sports. In the American patent with the publication number of U.S. Pat. No. 4,199,136A, an elastically bendable semi-rigid plate is used as elastic component. However, the supporting problem of plate end turning angles and plate end distance shortening caused by plate bending cannot be completely solved, so that the fluctuating range of the plate can be limited, and friction noise is easily generated. Similar to a trampoline structure, in the American patent with the publication number of U.S. Pat. No. 4,037,834A, disclosed is a jogging platform with a spring structure. Four-sided tension springs are used to hang plywood. The four-sided tensioned plywood just serves as a pedal platform, but cannot be bent effectively, mainly relying on tension springs to store energy, so that the elastic effects of deep bending and effective energy storage of the pedal cannot be achieved.

Apparently, the described embodiments are merely a part rather than all of the embodiments of the present disclosure. Based on the embodiment in the present disclosure, all other embodiments acquired by the ordinary technical staff in the art under the premise of without contributing creative labor belong to the scope protected by the present disclosure.
One of the purposes of the present disclosure is to provide a novel trampoline. Through a bilaterally and elastically supported elastic assembly, the elastic performance of the trampoline can be improved, and the problems of the turning angles at both supported ends of the elastic plate and the change of the horizontal distance between both supported ends of the elastic plate due to the bending of the elastic assembly so as to limit the fluctuating amplitude of the elastic assembly and easily generate the friction noise in the prior art can also be solved.
The other of the purposes of the present disclosure is to further provide an elastic system provided with the trampoline.
To make the foregoing objective, features and advantages of the present disclosure clearer and more comprehensible, the present disclosure is further described in detail below with reference to the attached figures and specific embodiments.
As shown in
In the embodiment, both ends of the elastic assembly 1 are supported by providing the elastic support 2 with elastic energy storage characteristics, so that the overall elastic performance of the trampoline 100 can be improved, the fluctuating amplitude of the elastic assembly 1 is increased, and the friction noise generated when the elastic assembly 1 rises and falls is eliminated. Meanwhile, the adverse effects of the turning angles (both ends are mutually gathered) at both supported ends of the elastic plate and the change of the horizontal distance between both supported ends of the elastic plate due to the bending of the elastic plate on the support are also eliminated. The human body or other loads can move vertically up and down in the middle of the elastic assembly 1 by means of the elastic deformation of the elastic assembly 1 and the elastic support 2, so that the trampoline is beneficial to physical training, body building, entertainment and rehabilitation of people of different ages. Thus, in the embodiment, both ends of the elastic assembly 1 by are supported by the vertical supporting unit 21s, so that a vertical fluctuating movement device with a bilaterally, integrally and elastically supported elastic assembly. The bending elastic energy storage characteristics of the elastic assembly 1 and the excellent elastic energy storage characteristics of the elastic support 2 are fully utilized, and the adverse effects of the turning angles at the first end 11 and the second end 12 and the change of the horizontal distance between the first end 11 and the second end 12 on the support effect of the elastic assembly 1 can be improved.
In the embodiment, two vertical supporting units 21 are symmetrically arranged at both ends of the horizontal supporting unit 22, and the elastic support 2 is of a U-shaped elastic support structure with both high ends and slightly lower middle part. The structure is similar to a bed frame structure. In order to ensure the elastic energy storage capacity of the overall elastic support 2, preferably, the two vertical supporting units 21 and the horizontal supporting unit 22 can be elastically bent and deformed with the bending deformation of the elastic assembly 1, that is, the elastic support 2 can be elastically deformed as a whole.
Further, in the embodiment, the horizontal supporting unit 22 may be a horizontal elastic support plate 23, or a horizontal elastic support frame comprising bar frames. Accordingly, each vertical supporting unit 21 may be a vertical elastic support plate 25, or a vertical elastic support frame comprising bar frames. The two structural forms of the horizontal supporting unit 22 and the two structural forms of the vertical supporting unit 21 can be arbitrarily combined in pairs. Generally, the horizontal supporting unit 22 and the vertical supporting unit 21 are in the same structural form. For example, the horizontal supporting unit 22 is a horizontal elastic support plate 23, and the vertical supporting unit 21 is a vertical elastic support plate 25 at this time. Similarly, when the horizontal supporting unit 22 is a horizontal elastic support frame comprising bar frames, the vertical supporting unit 21 is also a vertical elastic support frame comprising bar frames. For the purpose of distinguishing, bar frames constituting the horizontal elastic support frame are defined as “horizontal elastic bar frames 24” and bar frames constituting the vertical elastic support frame are defined as “vertical bar frames 26”. Each horizontal elastic bar frame 24 and each vertical bar frame 26 may be of circular tube structures or square tube structures with a rectangular cross section.
The vertical supporting unit 21 and the horizontal supporting unit 22 can be made of metals with certain elasticity, engineering plastics or composite materials, such as metal materials with high strength and excellent elastic characteristics, glass fibers or carbon fiber composite materials, whether the unit is a support plate structure or a support frame structure. The cross-sectional structural parameters of the vertical supporting units 21 and the horizontal supporting unit 22 should ensure that the vertical supporting units 21 and the horizontal supporting unit 22 have necessary strength, stiffness and obvious elastic characteristics.
In practical application, the vertical supporting units 21 and the horizontal supporting unit 22 can be integrally formed. The vertical supporting units 21 and the elastic assembly 1 are roughly the same in widths. The two vertical supporting units 21 are separated from the outside of the first end 11 and the second end 12 of the elastic assembly 1, similar to a bed head with the same height as the elastic assembly 1, and can be tilted inward at a certain angle. The horizontal supporting unit 22, similar to a longitudinal beam of the bed frame, is fixed to the vertical supporting unit 21. Alternatively, the vertical supporting units 21 and the horizontal supporting unit 22 are connected through a torsion spring 27 (a strong torsion spring is generally used) or a bending leaf spring. The connectors between the vertical supporting units 21 and the horizontal supporting unit 22 can also be replaced with a series of replaceable components with different elasticity or sizes so as to meet different requirements of force and size for the trampoline.
In the embodiment, elastic legs 3 are further provided. The elastic legs 3 are arranged at the bottom of the elastic support 2, and specifically can be arranged at the bottoms of or adjacent to fixedly connected points of the vertical supporting units 21 and the horizontal supporting unit 22. The elastic legs 3, similar to bed legs, make contact with the ground, and support the elastic support 2, so that the bottoms of the horizontal supporting units 22 of the elastic support 2 keep necessary distance from the ground to avoid the horizontal supporting unit 22 from making contact with the ground when being bent under force. When the elastic assembly 1 is subjected to bending deformation, the elastic legs 3 can be subjected to elastic bending deformation or vertical elastic deformation under the traction effect of the elastic support 2. As a preferred scheme, the elastic legs 3 can be elastic components made of elastic polymer materials, engineering plastics or metal materials, and can bear certain bending and relative vertical displacement of upper and lower ends.
In the embodiment, the elastic assembly 1 is a rectangular elastic flat plate 13. Both ends of the rectangular elastic flat plate 13 in the length direction are the first end 11 and the second end 12 respectively. The thickness of the rectangular elastic flat plate 13 is uniform, or the thickness is gradually reduced from the middle to both ends in the length direction. The length-width ratio of the rectangular elastic flat plate 13 is preferably greater than 1 and less than 10. The rectangular elastic flat plate 13 can be made of elastic thin plates, such as composite materials, wooden boards and metal plates, and the thickness dimension is less than one tenth of the side length dimension. Alternatively, the elastic assembly 1 is an arched elastic plate. The vertical projection of the arched elastic plate is rectangular. Both ends of the arched elastic plate in the length direction are the first end 11 and the second end 12 respectively. The thickness of the arched elastic plate is uniform, or the thickness is gradually reduced from the middle to both ends in the length direction. The length-width ratio of the arched elastic flat plate is preferably greater than 1 and less than 10. The arched elastic flat plate can be made of elastic thin plates, such as composite materials, wooden boards and metal plates, and the thickness dimension is less than one tenth of the side length dimension. Alternatively, the elastic assembly 1 includes a rectangular elastic frame 14. A plurality of supporting crossbars 15 arranged at intervals along a length direction of the rectangular elastic frame 14 are embedded inside the rectangular elastic frame 14. The supporting crossbars 15 are parallel to each other and uniformly distributed at intervals. The rectangular elastic frame 14 is internally covered with an elastic thin plate or elastic fabric 16. Both ends of the rectangular elastic frame 14 in the length direction are the first end 11 and the second end 12 respectively. The elastic fabric 16 woven from load-bearing ropes, nets and cloth used in the trampoline plays the same role as the rectangular elastic flat plate 13 in carrying human body weight and storing energy by bending elasticity, and is a brand-new trampoline. The rectangular elastic frame 14 and the supporting crossbars 15 can be made of glass fiber composite materials, carbon fiber composite materials or metal materials, are high in deformation energy storage capacity, and can realize an elastic function different from the traditional trampoline but similar to the elastic plate.
In the embodiment, the connecting units have a swing function and are used in groups. The first end 11 and the second end 12 of the elastic assembly 1 are respectively connected with the respective vertical supporting units 21 through two connecting units. Any one of the connecting units is one of a hinged connector 4, an elastic corner connector 5 and a flexible corner connector 6.
One end of the hinged connector 4 is connected with the first end 11 or the second end 12 of the elastic assembly 1, the other end of the hinged connector 4 is connected with the corresponding vertical supporting unit 21, the first end 11 or the second end 12 of the elastic assembly 1 are hinged with the corresponding vertical supporting unit 21 through the hinged connector 4. Hinged connection means that a certain turning angle can be formed without separation, and hinged connection can be realized by coaxial hinged connection of holes, shafts, bearings and shaft sleeves. In the embodiment, when horizontally arranged pipe fittings are arranged at the upper ends of the vertical supporting units 21 on the same side, one end of the hinged connector 4 can be provided with an outer sliding sleeve which is in shaft and sleeve fit with the horizontally arranged pipe fittings.
The elastic corner connector 5 is a polymer elastic component or a metal elastic component. One end of the elastic corner connector 5 is connected with the first end 11 or the second end 12 of the elastic assembly 1, and the other end of the elastic corner connector 5 is connected with the corresponding vertical supporting unit 21. Both ends of the elastic corner connector 5 can be elastically deformed by external force. The polymer elastic component or the metal elastic component can be a leaf spring, a coil spring and the like.
The flexible corner connector 6 is a connecting chain, a connecting rope or a connecting belt. A fixed end of the flexible corner connector 6 is directly connected with the corresponding vertical supporting unit 21 or is connected with the corresponding vertical supporting unit 21 through a spring. An adjusting end of the flexible corner connector 6 penetrates a connecting hole of the first end 11 or the second end 12 and then turns over to the fixed end, and is connected with the fixed end through a buckle 7 or a nylon buckle to adjust the length and tightness of the flexible corner connector 6. The flexible corner connector 6 specifically can be a chain, a rope and a belt. The first end 11, the second end 12 and the vertical supporting units 21 are all provided with corresponding lifting rings, lifting buckles and other structures for the flexible corner connector 6 to penetrate and connect. The characteristics of connection through suspenders and lifting rings are utilized. The flexible corner connector 6 is connected with the vertical supporting unit 21 by a spring to further improve and adjust the elastic performance of the trampoline.
In the embodiment, taking the elastic assembly 1 as a rectangular elastic flat plate 13 as an example, the rectangular elastic flat plate 13 can be at least one of A to E:
In the embodiment, a follow-up armrest 9 can be installed on the elastic assembly 1 or the vertical supporting units 22 as required, and a follow-up stool, a chair, a deck chair, a saddle seat 8, a pedal 10, a bed guard can be installed on the elastic assembly 1 to facilitate movement in different postures, body relaxation and health recovery. The follow-up bed frame or a slightly larger plate or other structural bodies can be installed on the elastic assemblies 1 of two trampolines 100 to achieve fluctuating movement experience. The elastic assembly 1 is provided with an electronic counter or a vibration sensor to display on the follow-up armrest 9, so that the number of vertical fluctuating movement is conveniently mastered. As shown in
The operation principle of the trampoline 100 is described in detail below by taking the trampoline as an example in which the elastic assembly 1 is a rectangular elastic flat plate 13 and the rectangular elastic flat plate 13 is installed to the vertical supporting units 21 through the flexible corner connectors 6.
When the middle of the rectangular elastic flat plate 13 fluctuates up and down under the press of human body, the rectangular elastic flat plate 13 is bent, the first end 11 and the second end 12 are turned to change symmetrically. The horizontal distance between the first end 11 and the second end 12 tends to become shorter, and the distance between the tops of the two vertical supporting units 21 also tends to become shorter under the pull of the connecting units. Then, the vertical supporting units 21 and the horizontal supporting unit 22 are subjected to symmetrical elastic bending deformation to gather elastic potential energy, and the elastic legs 3 are deformed accordingly, the middle part of the rectangular elastic flat plate 13 is not subjected to obvious depression under the pull and support of the elastic support 2. When the pressure is decreased or disappears after spring back, the bending deformation of the rectangular elastic flat plate 13 is decreased or disappears, the elastic deformation corresponding to the elastic support 2 is simultaneously decreased or disappears, the deformation of the elastic legs 3 is decreased or disappears, the turning angles of the first end 11 and the second end 12 tend to reset, and the horizontal distance between the first end 11 and the second end 12 returns to an initial state. The elastic legs 3 are installed close to bending inflection points of the elastic support 2, so that the elastic legs 3 have a small displacement tendency when the horizontal supporting unit 22 is bent.
Thus, it can be seen that the trampoline 100 proposed in the technical scheme fully utilizes the excellent deep-bending energy storage and release characteristics of the elastic thin plate and superimposes the elastic energy storage effect supported by the integral elastic support, and provides a vertical undulating movement device for sports training, fitness, entertainment, body relaxation and rehabilitation with excellent body feeling, large fluctuating amplitude, low noise and small land occupation.
The trampoline 100 provided by the technical scheme adopts a correct and effective method to solve the problem of how to support when the elastic thin plate is bent under force so that both supported ends are subjected to turning and displacement. At the same time, energy is stored by the bending deformation of the integral elastic support 2, so that the fluctuating movement device with an elastic plate has better elastic characteristics.
The present disclosure provides an elastic system, including a plurality of trampolines 100 disclosed in the first embodiment. The trampolines 100 are jointly supported at the bottom of a bed frame or a flat plate. For example, the follow-up bed frame or a slightly larger plate or other structural bodies can be installed on the elastic assembly 1 of two trampolines 100 to achieve fluctuating movement experience.
