Description

Technical Field

[0001] The present invention belongs to the field of sports equipment, relates to jumping equipment, and particularly relates to a trampoline and an elastic system.

Background Art

[0002] As a sports and entertainment equipment, trampolines are popular among people, especially children and young people. However, due to being too soft and difficult to stand stably, they are not suitable for middle-aged and elderly people. The single-sided diving board for jumping is easy to stand stably, but it is too large and complicated for indoor jumping. In Chinese Patent (Patent Document 1) with Publication No. CN102553128A, a spring-supported rigid flat plate is adopted as a jumping exercise device, but it is limited by the linear characteristics of the compression spring and affects the exercise feeling. In US Patent (Patent Document 2) with Publication No. US4199136A, an elastically bendable semi-rigid thin plate is adopted as an elastic element, but the support problems caused by the rotation of the plate end due to the bending of the thin plate and the shortening of the distance of the plate end cannot be completely solved. Therefore, the lifting and lowering range of the thin plate is limited and friction noise is likely to occur. In US Patent (Patent Document 3) with Publication No. US4037834A similar to the trampoline structure, a jogging platform with a spring structure is disclosed. It uses four-side tension springs to suspend a plywood, and the plywood suspended on the four sides is only used as a pedal platform and cannot be effectively bent. Since it mainly depends on the energy storage by the tension springs, the elastic effect of deeply bending the pedal to effectively store energy cannot be achieved.

[Modes for carrying out the invention]

[0019] The technical solutions in embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments. Clearly, the embodiments described are only a subset of the present invention, not all embodiments. All other embodiments that a person skilled in the art could obtain without creative effort based on the embodiments of the present invention fall within the technical scope of the present invention.

[0020] One of the objectives of the present invention is to provide a new type of trampoline that not only improves the elastic performance of an elastic member by elastically supporting it on both sides, but also solves the problems of the conventional technology in which bending of the elastic member causes both supported ends of the elastic member to rotate, and the horizontal distance between the supported plate ends of the elastic member changes, limiting the range of motion of the elastic member and making it easier for friction noise to occur.

[0021] Another object of the present invention is to provide an elastic system having the above-described trampoline.

[0022] To make the above-mentioned objectives, features, and advantages of the present invention clearer and easier to understand, the present invention will be described in more detail below with reference to the drawings and specific embodiments.

[0023] <Example 1> As shown in Figures 4 and 5, this embodiment provides a trampoline 100, which includes an elastic member 1 and an elastic bracket 2, the elastic member 1 having a first end 11 and a second end 12, the portion of the elastic member 1 located between the first end 11 and the second end 12 being a bending energy storage body, used for placing objects or for a person to stand on, and generally, the elastic member 1 is preferably a rectangular structure or a rectangular structure in its vertical projection, the first end 11 and the second end 12 being the ends located in the longitudinal direction of the elastic member 1, respectively. The elastic bracket 2 includes a vertical support unit 21 and a horizontal support unit 22. The horizontal support unit 22 has two sets of vertical support units 21 spaced apart, and each set of vertical support units 21 is connected to the first end 11 and the second end 12 of the elastic member 1 via connecting units, providing double-sided support and pre-tensioning to the elastic member 1. Preferably, both the first end 11 and the second end 12 of the elastic member 1 are connected to the corresponding vertical support unit 21 via multiple sets of connecting units, so that both the first end 11 and the second end 12 of the elastic member 1 form multi-point connections with the corresponding vertical support unit 21, thereby preventing rotation relative to the elastic bracket 2 when the elastic member 1 is bent and deformed, and improving the stability of the trampoline. Simultaneously, when the elastic member 1 undergoes bending deformation, the tensile action of its first end 11 and second end 12 drives at least one of the vertical support unit 21 and horizontal support unit 22 to undergo elastic bending deformation, applying a symmetrical elastic restoring force to the first end 11 and second end 12 of the elastic member 1, limiting (or "resisting") the change in the horizontal distance between the first end 11 and the second end 12 during the bending deformation of the elastic member 1. When the central part of the elastic member 1 is subjected to a vertical force, it is compressed and bent, and both ends rotate (bend), so the horizontal distance between the ends of the elastic member 1 changes. This is an unavoidable force process during the use of the elastic member 1, and correspondingly, the vertical support unit 21 supporting both ends of the elastic member 1 also changes in accordance with the change in the horizontal distance between the ends of the elastic member 1.However, since at least one of the vertical support units 21 (here referring to two sets of vertical support units 21) and the horizontal support units 22 can generate elastic bending deformation in conjunction with the bending deformation of the elastic member 1, the elastic bracket 2 has a constant elastic energy storage characteristic, and when the horizontal distance between both ends of the elastic member 1 changes, a reaction force can be applied to both ends of the elastic member 1, which can help the central part of the elastic member 1 to quickly return to its original position, thus preventing the elastic member 1 from shifting overall when it is bent under force, and improving the elastic force and support force of the elastic member 1.

[0024] This embodiment significantly improves the overall elastic performance of the trampoline 100 by installing an elastic bracket 2 having elastic energy storage properties to support both ends of the elastic member 1, increasing the range of motion of the elastic member 1, eliminating friction noise generated when the elastic member 1 moves up and down, and simultaneously eliminating the adverse effects on support caused by the bending of the elastic plate, which causes the supported ends of the elastic plate to rotate (the ends to come together) and the horizontal distance between the supported ends of the elastic plate to change. The human body or other loads can perform vertical up and down motion at the center of the elastic member 1 by utilizing the elastic deformation of the elastic member 1 and elastic bracket 2, which is advantageous for sports training, fitness, recreation, and rehabilitation exercises for people of different age groups. As can be seen from the above, this embodiment forms a vertical undulation motion device for an elastic member in which both sides are elastically supported, by supporting both ends of the elastic member 1 with a vertical support unit 21, thereby making full use of the bending elastic energy storage characteristics of the elastic member 1 and the excellent elastic energy storage characteristics of the elastic bracket 2, and improving the adverse effects on the support effect of the elastic member 1 caused by the rotation of the first end 11 and the second end 12 and the change in the horizontal distance between the first end 11 and the second end 12.

[0025] In this embodiment, two sets of vertical support units 21 are symmetrically provided at both ends of the horizontal support unit 22, and the elastic bracket 2 as a whole exhibits a U-shaped elastic bracket structure with higher ends and a slightly lower center, similar to a bed frame structure. In order to ensure the elastic energy storage capacity of the entire elastic bracket 2, it is preferable that both sets of vertical support units 21 and horizontal support units 22 generate elastic bending deformation in conjunction with the bending deformation of the elastic member 1, that is, that the entire elastic bracket 2 can be elastically deformed.

[0026] Furthermore, in this embodiment, the horizontal support unit 22 may be a horizontal elastic support frame consisting of a combination of horizontal elastic support plates 23 or bar frames, and correspondingly, the vertical support unit 21 may be a vertical elastic support frame consisting of a combination of vertical elastic support plates 25 or bar frames. The two structural forms of the horizontal support unit 22 and the two structural forms of the vertical support unit 21 can be combined in any two-to-two combinations. Generally, the horizontal support unit 22 and the vertical support unit 21 adopt the same structural form. For example, the horizontal support unit 22 is a horizontal elastic support plate 23, and in this case, the vertical support unit 21 is a vertical elastic support plate 25. Similarly, if the horizontal support unit 22 is a horizontal elastic support frame consisting of a combination of bar frames, then the vertical support unit 21 is also a vertical elastic support frame consisting of a combination of bar frames. To distinguish between them, the bar frames constituting the horizontal elastic support frame are defined as "horizontal elastic bar frames 24," and the bar frames constituting the vertical elastic support frame are defined as "vertical bar frames 26." The horizontal elastic bar frames 24 and the vertical bar frames 26 may be circular tube structures or rectangular tube structures with a rectangular cross-section.

[0027] The vertical support unit 21 and horizontal support unit 22 described above may be a support plate structure or a support frame structure, and may be manufactured from a metal, engineering plastic, or composite material with a certain degree of elasticity, such as a metal material, glass fiber, or carbon fiber composite material, which has high strength and excellent elastic properties. The cross-sectional structural parameters of the vertical support unit 21 and horizontal support unit 22 should be such that the vertical support unit 21 and horizontal support unit 22 have the required strength, rigidity, and clear elastic properties.

[0028] In practical applications, the vertical support units 21 and horizontal support units 22 may be molded as a single unit, the vertical support units 21 being approximately the same width as the elastic member 1, and the two sets of vertical support units 21 positioned outside the first end 11 and second end 12 of the elastic member 1, resembling a bed head at the same height as the elastic member 1, and capable of being tilted inward at a certain angle. The horizontal support units 22 are similar to the longitudinal beams of a bed frame and are fixedly connected to the vertical support units 21. Alternatively, the vertical support units 21 and horizontal support units 22 may be connected via torsion springs 27 (typically strong torsion springs) or folded leaf springs. The connecting members between the vertical support units 21 and horizontal support units 22 may also be replaced with a series of interchangeable members of different elasticity or sizes to meet the different force and size needs of the trampoline.

[0029] In this embodiment, elastic support legs 3 are further provided, which are located at the bottom of the elastic bracket 2, specifically at or near the bottom of the fixed connection point between the vertical support unit 21 and the horizontal support unit 22. The elastic support legs 3 are in contact with the ground and are similar to bed legs. By supporting the elastic bracket 2, they maintain the necessary distance between the bottom of the horizontal support unit 22 of the elastic bracket 2 and the ground, preventing the horizontal support unit 22 from contacting the ground when it is subjected to force and bent. The elastic support legs 3 can generate elastic bending deformation or vertical elastic deformation by the tensile action of the elastic bracket 2 when the elastic member 1 undergoes bending deformation. As a preferred solution, the elastic support legs 3 may be made of an elastic polymer material, engineering plastic, or metal material, and can withstand a certain degree of bending and relative vertical displacement of the upper and lower ends.

[0030] In this embodiment, the elastic member 1 may be a rectangular elastic plate 13, where both ends in the longitudinal direction of the rectangular elastic plate 13 are a first end 11 and a second end 12, respectively, and the thickness of the rectangular elastic plate 13 is uniform, or the thickness gradually decreases from the center to both ends in the longitudinal direction. Preferably, the aspect ratio of the rectangular elastic plate 13 is greater than 1 and less than 10, and it may be manufactured from a thin sheet of elastic material such as a composite material, a wooden board, or a metal plate, and the thickness dimension is less than one-tenth of the side length dimension. Alternatively, the elastic member 1 is an arched elastic plate, where the vertical projection of the arched elastic plate is rectangular, where both ends in the longitudinal direction of the arched elastic plate are a first end 11 and a second end 12, respectively, and the thickness of the arched elastic plate is uniform, or the thickness gradually decreases from the center to both ends in the longitudinal direction. The ratio of the length of the long side to the length of the short side of the arched elastic plate is preferably greater than 1 and less than 10, and it may be made of an elastic material sheet such as a composite material, a wooden board, or a metal plate, and the thickness dimension is less than one-tenth of the side length dimension. Alternatively, the elastic member 1 includes a rectangular elastic frame 14, and inside the rectangular elastic frame 14 are a plurality of support crossbars 15 which are spaced apart along the longitudinal direction of the rectangular elastic frame 14, and the plurality of support crossbars 15 are parallel and spaced apart and uniformly distributed, and the inside of the rectangular elastic frame 14 is covered with an elastic sheet or elastic fabric 16, and the ends of the rectangular elastic frame 14 in the longitudinal direction are the first end 11 and the second end 12, respectively. The elastic fabric 16 may be woven from load-bearing ropes, nets, or cloths used in trampolines, and it plays the same role as the rectangular elastic plate 13 in supporting the weight of the human body and storing bending elastic energy, and is a new trampoline. The rectangular elastic frame 14 and the support crossbar 15 may both be made of glass fiber composite material, carbon fiber composite material, or metal material, and have a strong deformation energy storage capacity, enabling elastic functions similar to those of an elastic board, although different from conventional trampolines.

[0031] In this embodiment, the connecting units have a swinging function and are used as a set. The first end 11 and the second end 12 of the elastic member 1 are connected to the corresponding vertical support unit 21 via two sets of connecting units. One of the connecting units is one of the hinge connecting member 4, the elastic corner connecting member 5, and the flexible corner connecting member 6. One end of the hinge connecting member 4 is connected to the first end 11 or the second end 12 of the elastic member 1, and the other end of the hinge connecting member 4 is connected to the vertical support unit 21. The first end 11 and the second end 12 of the elastic member 1 are hinged to the corresponding vertical support unit 21 via the hinge connecting member 4. A hinge connection is one in which a certain amount of rotation occurs and separation does not occur. A hinge connection can be realized by a coaxial hinge connection method such as a hole, shaft, bearing, or shaft sleeve. In this embodiment, if the upper end of the vertical support unit 21 on the same side is a horizontally positioned pipe member, one end of the hinge connecting member 4 may be an outer slide sleeve, which forms a shaft-sleeve fitting with this horizontally positioned pipe member.

[0032] The elastic corner connecting member 5 is a polymer elastic member or a metallic elastic member. One end of the elastic corner connecting member 5 is connected to the first end 11 or the second end 12 of the elastic member 1, and the other end of the elastic corner connecting member 5 is connected to the vertical support unit 21. The space between the two ends of the elastic corner connecting member 5 can be elastically deformed by external forces. The polymer elastic member or metallic elastic member may be a leaf spring, a coil spring, or the like.

[0033] The flexible corner connecting member 6 is a connecting chain, connecting rope, or connecting belt. The fixed end of the flexible corner connecting member 6 is directly connected to the vertical support unit 21 or connected to the vertical support unit 21 via a spring. The adjustable end of the flexible corner connecting member 6 passes through the connecting hole of the first end 11 or the second end 12, then folds back to the fixed end and is connected to the fixed end via a buckle 7 or nylon buckle, etc., to adjust the length and looseness of the flexible corner connecting member 6. Specifically, the flexible corner connecting member 6 may be a chain, rope, or belt. The first end 11, the second end 12, and the corresponding vertical support unit 21 are provided with corresponding structures such as suspension rings and suspension fittings, through which the flexible corner connecting member 6 passes and connects. The connection characteristics of the suspension strap and suspension ring are utilized. The flexible corner connecting member 6 is connected to the vertical support unit 21 via a spring, which can further improve and adjust the elastic performance of the trampoline.

[0034] In this specific embodiment, the elastic member 1 is taken as a rectangular elastic plate 13, and at least one of A to E can be used for the rectangular elastic plate 13. A: A flat plate with trapezoidal notches that gradually narrow in width is provided between multiple adjacent traction points at both ends, thereby increasing the elastic deformation width of the rectangular elastic plate 13. B: The surface layer and intermediate layer will be made of a composite panel with different material and structural designs. C: The bottom plate or surface of the rectangular elastic plate 13 is provided with longitudinal reinforcing ribs and strips, and a reinforcing plate is provided in the center (to avoid excessive bending in the center). D: A fabric traction reinforcement net and belt are provided on the bottom plate of the rectangular elastic plate 13. E: A polymer material buffer layer, a woven fabric buffer layer, and a pad are provided on the surface of the rectangular elastic plate 13, either entirely or locally, and a polymer material buffer pad can be provided in the central part of the horizontal support unit 22 as a groundable buffer.

[0035] In this embodiment, a follow-up handrail 9 can be attached to the elastic member 1 or vertical support unit 22 as needed, and a follow-up bench, chair, recliner, saddle seat 8, pedal 10, bed guard, etc. can be attached to the elastic member 1, which is useful for exercise in different postures, physical relaxation, and physical health recovery. A follow-up bed frame can be attached and fixed to the elastic member 1 of the two trampolines 100, or a slightly larger flat plate or other structure can be stacked and installed to experience wave-like undulation. An electronic counter or vibration sensor can be attached to the elastic member 1 and displayed on the follow-up handrail 9, etc., which helps the user to keep track of the number of up-and-down movements. As shown in Figure 14, the trampoline 100 is equipped with a follow-up handrail 9, a saddle seat 8 and pedal 10, which is an application extension of a vertical undulation exercise device of an elastic plate whose entire sides are elastically supported, and which mimics horseback riding.

[0036] The operating principle of the trampoline 100 will be specifically explained below, using as an example that the elastic member 1 in the trampoline 100 is a rectangular elastic plate 13, and that the rectangular elastic plate 13 is attached to the vertical support unit 21 by a flexible corner connecting member 6.

[0037] When the central part of the rectangular elastic plate 13 undulates vertically due to changes in pressure from the human body, the rectangular elastic plate 13 undergoes a bending change, causing the first end 11 and the second end 12 to undergo a constant symmetrical rotational change, and the horizontal distance between the first end 11 and the second end 12 tends to shorten. With the traction of the connecting unit, the distance between the tops of the two sets of vertical support units 21 also tends to shorten, causing the vertical support unit 21 and the horizontal support unit 22 to undergo a corresponding symmetrical elastic bending deformation and accumulate elastic potential energy, while the elastic support leg 3 undergoes a constant deformation. Meanwhile, the central part of the rectangular elastic plate 13 does not undergo a noticeable indentation due to the traction and support of the elastic bracket 2. When the pressure decreases or disappears after rebound, the bending deformation of the rectangular elastic plate 13 decreases or disappears, the corresponding elastic deformation of the elastic bracket 2 decreases or disappears simultaneously, the deformation of the elastic support leg 3 decreases or disappears, the rotation of the first end 11 and the second end 12 tends to recover, and the horizontal distance between the first end 11 and the second end 12 returns to its initial state. Since the mounting position of the elastic support leg 3 is close to the inside and below the bending inflection point of the elastic bracket 2, it is necessary to cause the elastic support leg 3 to exhibit a small displacement tendency when the horizontal support unit 22 bends.

[0038] As can be seen from the above, the trampoline 100 provided by this technical solution fully utilizes the excellent deep bending energy storage and release characteristics of elastic thin plates, and by superimposing the elastic energy storage effect supported by the overall elastic bracket, it provides a vertical elevation exercise device for sports training, fitness, entertainment, physical relaxation, and rehabilitation exercises that offers a superior feel, a large range of motion, low noise, and a small footprint.

[0039] The trampoline 100 proposed by this technical solution employs a precise and effective method to solve the difficult problem of how to support the elastic thin plate when it is subjected to force and bent, and when the supported ends rotate and displace. At the same time, by utilizing the bending deformation of the entire elastic bracket 2 to store energy, the elastic plate luffing motion device is given even better elastic properties.

[0040] <Example 2> This embodiment provides an elastic system, comprising a plurality of trampolines 100 disclosed in Embodiment 1, the plurality of trampolines 100 together supported at the bottom of a bed frame or flat plate. For example, a follow-up bed frame can be attached and fixed to the elastic members 1 of two sets of trampolines 100, or a slightly larger flat plate or other structure can be stacked and installed to experience wave-like undulation.
