Trampoline and elastic system

Abstract

A trampoline (100) and an elastic system. The trampoline (100) comprises: an elastic member (1) having a first end (11) and a second end (12), wherein the portion of the elastic member (1) between the first end (11) and the second end (12) is a curved energy storage body; and an elastic support (2) comprising vertical support units (21) and a horizontal support unit (22), wherein two sets of vertical support units (21) are arranged on the horizontal support unit (22) in a spaced manner, and the two sets of vertical support units (21) are respectively connected to the first end (11) and the second end (12) of the elastic member (1) by means of connecting units for bilateral supporting and pre-tensioning of the elastic member (1). In addition, when the elastic member (1) is bent and deformed, at least one of the vertical support units (21) and the horizontal support unit (22) can be driven to elastically bend and deform, such that a symmetrical elastic restoring force is applied to the first end (11) and the second end (12) of the elastic member (1) to limit a change in the horizontal distance between the first end (11) and the second end (12) during the bending and deformation of the elastic member (1). The trampoline (100) not only improves the elastic performance of the elastic member (1), but also solves the problems that the amplitude of rise and fall of the elastic member (1) is limited and friction noise may easily be generated due to angular rotation at the two supported ends of the elastic member (1) and a change in the horizontal distance between the two supported ends of the elastic member (1) caused by the bending of the elastic member (1).

Description

Trampoline and elastic system Technical Field

[0001] The invention belongs to the field of sports equipment and relates to a jumping device, in particular to a trampoline and an elastic system. Background Art

[0002] Trampolines are popular as sports and entertainment equipment, especially for children and young people. However, they are too soft and difficult to stand on, making them unsuitable for middle-aged and elderly people. Cantilever springboards for diving, while easy to stand on, are too large and complex for indoor jumping. Chinese patent publication number CN102553128A uses a spring-supported rigid flat plate as a jumping exerciser, but this is limited by the linear characteristics of the compression spring, which affects the sense of movement. U.S. patent publication number US4199136A uses elastically bendable semi-rigid thin plates as elastic elements, but because it fails to completely solve the support problems caused by the plate end corners and the shortened distance between the plate ends due to the bending of the thin plate, it limits the plate's rise and fall range and is prone to friction noise. Similar to the trampoline structure, U.S. patent publication number US4037834A discloses a jogging platform with a spring structure, which uses four-sided tension springs to suspend a plywood board. The four-sided suspended plywood board only serves as a pedal platform and cannot be effectively bent. Instead, it relies mainly on the tension springs to store energy, which cannot achieve the elastic effect of deep bending of the pedal to effectively store energy.

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 are within the scope of protection of the present invention.

[0054] One of the purposes of the present invention is to provide a new type of trampoline, which, by elastically supporting the elastic members on both sides, can not only improve the elastic performance of the elastic members, but also solve the problem existing in the prior art that the elastic members bend, causing the supported ends of the elastic members to rotate and the horizontal distance between the supported plate ends of the elastic members to change, thereby limiting the rising and falling range of the elastic members and easily generating friction noise.

[0055] Another object of the present invention is to provide a spring system having the above-mentioned trampoline.

[0056] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] Example 1

[0058] As shown in Figures 4 and 5, this embodiment provides a trampoline 100, including an elastic member 1 and an elastic support 2. The elastic member 1 has a first end 11 and a second end 12. The portion of the elastic member 1 between the first end 11 and the second end 12 is a curved energy storage body used for carrying objects or for a person to stand on. Generally, the elastic member 1 is preferably a rectangular structure or a structure whose vertical projection is a rectangle. The first end 11 and the second end 12 are respectively the two ends of the elastic member 1 in the length direction. The elastic support 2 includes a vertical support unit 21 and a horizontal support unit 22. Two groups of vertical support units 21 are arranged on the horizontal support unit 22 at intervals. The two groups of vertical support units 21 are respectively connected to the first end 11 and the second end 12 of the elastic member 1 through connecting units to provide bilateral support and pre-tensioning for the elastic member 1. Preferably, the first end 11 and the second end 12 of the elastic member 1 are connected to the corresponding vertical support units 21 through multiple groups of connecting units, so that the first end 11 and the second end 12 of the elastic member 1 form multiple points with the corresponding vertical support units 21. The elastic member 1 is connected to the elastic support 2 to prevent it from rotating relative to the elastic support 2 when it is bent and deformed, thereby improving the stability of the trampoline. At the same time, when the elastic member 1 is bent and deformed, under the traction of the first end 11 and the second end 12, it can drive at least one of the vertical support unit 21 and the horizontal support unit 22 to undergo elastic bending deformation, so as to apply a symmetrical elastic restoring force to the first end 11 and the second end 12 of the elastic member 1, thereby limiting (or "resisting") the change in the horizontal distance between the first end 11 and the second end 12 of the elastic member 1 during the bending deformation process. When the middle part of the elastic member 1 is subjected to vertical force, it is compressed and bent, and the two ends are turned (curled), thereby causing the horizontal distance between the two ends of the elastic member 1 to change. This is an inevitable force-bearing process of the elastic member 1 during use. Correspondingly, the vertical support units 21 that support the two ends of the elastic member 1 will also change with the change of the horizontal distance between the two ends of the elastic member 1; however, since at least one of the vertical support units 21 (here refers to two groups of vertical support units 21) and the horizontal support units 22 can elastically bend and deform with the bending deformation of the elastic member 1, the elastic bracket 2 has a certain elastic energy storage characteristic, and can apply a reaction force to the two ends of the elastic member 1 when the horizontal distance between the two ends of the elastic member 1 changes, which can help the middle part of the elastic member 1 to quickly reset, avoid the overall displacement of the elastic member 1 when it is bent under force, and improve the elastic force and supporting force of the elastic member 1.

[0059] This embodiment provides an elastic bracket 2 with elastic energy storage characteristics to support the two ends of the elastic member 1, which can significantly improve the overall elastic performance of the trampoline 100, increase the rising and falling amplitude of the elastic member 1 and eliminate the friction noise generated by the rising and falling of the elastic member 1. At the same time, it can eliminate the adverse effects on the support caused by the bending of the elastic plate, the rotation of the supported ends of the elastic plate (the two ends converge with each other) and the change in the horizontal distance between the supported ends of the elastic plate. The human body or other loads can move vertically up and down in the middle of the elastic member 1 by utilizing the elastic deformation of the elastic member 1 and the elastic bracket 2, which is beneficial to sports training, fitness, entertainment and rehabilitation exercises for people of different age groups. As can be seen from the above, this embodiment supports the two ends of the elastic member 1 through the vertical support unit 21, thereby forming a bilateral integral elastic support vertical undulating motion device for the elastic member, which fully utilizes the bending elastic energy storage characteristics of the elastic member 1 and the excellent elastic energy storage characteristics of the elastic bracket 2, and can improve the adverse effects of the corner rotation between 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 on the supporting effect of the elastic member 1.

[0060] In this embodiment, two sets of vertical support units 21 are symmetrically arranged at either end of the horizontal support unit 22. The elastic support 2 forms a U-shaped elastic support structure with higher ends and a slightly lower center, similar to a bed frame. To ensure the elastic energy storage capacity of the elastic support 2, the two sets of vertical support units 21 and the horizontal support unit 22 are preferably able to elastically bend and deform with the bending deformation of the elastic member 1, that is, the elastic support 2 can be elastically deformed as a whole.

[0061] Furthermore, in this embodiment, the horizontal support unit 22 can be a horizontal elastic support plate 23 or a horizontal elastic support frame composed of a rod frame combination; correspondingly, the vertical support unit 21 can be a vertical elastic support plate 25 or a vertical elastic support frame composed of a rod frame combination. The two structural forms of the above-mentioned horizontal support unit 22 and the two structural forms of the vertical support unit 21 can be combined in any two. 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 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 composed of a rod frame combination, then the vertical support unit 21 is also a vertical elastic support frame composed of a rod frame combination. In order to distinguish them, the rod frame constituting the horizontal elastic support frame is defined as a "horizontal elastic rod frame 24", and the rod frame constituting the vertical elastic support frame is defined as a "vertical rod frame 26". The horizontal elastic rod frame 24 and the vertical rod frame 26 can be a circular tube structure or a square tube structure with a rectangular cross-section.

[0062] The vertical support units 21 and horizontal support units 22, whether in the form of support plates or support frames, can be made of metal, engineering plastics, or composite materials with a certain degree of elasticity, such as high-strength and excellently elastic metal materials, or glass fiber or carbon fiber composite materials. The cross-sectional structural parameters of the vertical support units 21 and horizontal support units 22 should ensure that they possess the necessary strength, rigidity, and significant elastic properties.

[0063] In actual use, the vertical support units 21 and horizontal support units 22 can be integrally formed. The vertical support units 21 are approximately the same width as the elastic member 1. Two sets of vertical support units 21 are located outside the first end 11 and the second end 12 of the elastic member 1, similar to a headboard at the same height as the elastic member 1 and can be tilted inward at a certain angle. The horizontal support units 22 are fixedly connected to the vertical support units 21, similar to the longitudinal beams of the bed frame. Alternatively, the vertical support units 21 and the horizontal support units 22 are connected by torsion springs 27 (typically strong torsion springs) or bent leaf springs. The connecting parts between the vertical support units 21 and the horizontal support units 22 can also be replaced with a series of interchangeable components with different elastic forces or sizes to meet different strength and size requirements of the trampoline.

[0064] In this embodiment, an elastic support foot 3 is further provided. The elastic support foot 3 is disposed at the bottom of the elastic support 2, specifically at or near the connection point between the vertical support unit 21 and the horizontal support unit 22. The elastic support foot 3 contacts the ground, similar to the foot of a bed, and supports the elastic support 2, maintaining a necessary distance between the bottom of the horizontal support unit 22 of the elastic support 2 and the ground, thereby preventing the horizontal support unit 22 from contacting the ground when bending under force. The elastic support foot 3 is capable of elastically bending and deforming or vertically deforming under the traction of the elastic support 2 when the elastic member 1 bends and deforms. As a preferred embodiment, the elastic support foot 3 can be made of an elastic polymer material, engineering plastic, or metal elastic element, capable of withstanding a certain degree of bending and vertical displacement of the upper and lower ends.

[0065] In this embodiment, the elastic member 1 can be a rectangular elastic plate 13, the two ends of the rectangular elastic plate 13 in the longitudinal direction are respectively a first end 11 and a second end 12, the thickness of the rectangular elastic plate 13 is uniform, or the thickness gradually decreases from the middle to the two ends in the longitudinal direction. The aspect ratio of the rectangular elastic plate 13 is preferably greater than 1 and less than 10, and it can be made of a thin plate of elastic material such as a composite material, a wooden plate, a metal plate, etc., and the thickness dimension is less than one tenth of the side length dimension. Alternatively, the elastic member 1 is an arched elastic plate, the vertical projection of the arched elastic plate is a rectangle, the two ends of the arched elastic plate in the longitudinal direction are respectively a first end 11 and a second end 12, the thickness of the arched elastic plate is uniform, or the thickness gradually decreases from the middle to the two ends in the longitudinal direction; the ratio of the long side length to the short side length of the arched elastic plate is preferably greater than 1 and less than 10, and it can be made of a thin plate of elastic material such as a composite material, a wooden plate, a metal plate, etc., 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, embedded within which are multiple support crossbars 15 spaced apart along the length of the rectangular elastic frame 14. The multiple support crossbars 15 are parallel and evenly spaced. The rectangular elastic frame 14 is covered with an elastic sheet or elastic fabric 16, with the longitudinal ends of the rectangular elastic frame 14 being a first end 11 and a second end 12, respectively. The elastic fabric 16 can be woven from load-bearing ropes, netting, or cloth used in trampolines, and performs the same functions as the rectangular elastic plate 13 in bearing the weight of the human body and storing bending elastic energy, thus creating a novel trampoline. Both the rectangular elastic frame 14 and the support crossbars 15 can be made of glass fiber composite materials, carbon fiber composite materials, or metal materials, possessing strong deformation and energy storage capabilities, thus achieving an elastic function similar to that of an elastic plate, unlike that of a traditional trampoline.

[0066] In this embodiment, the connecting units have a swinging function and are used in groups. The first end 11 and the second end 12 of the elastic member 1 are connected to the corresponding vertical support unit 21 through two groups of connecting units respectively; each connecting unit is one of the hinged connector 4, the elastic corner connector 5, and the flexible corner connector 6, wherein:

[0067] One end of the articulated connector 4 is connected to the first end 11 or the second end 12 of the elastic member 1, and the other end of the articulated connector 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 through the articulated connector 4; articulation means that a certain angle of rotation can occur without separation, and the articulation can be achieved by coaxial articulation methods such as holes, shafts, bearings, and sleeves; in this embodiment, when the upper end of the vertical support unit 21 on the same side is a horizontally arranged pipe fitting, one end of the articulated connector 4 can be an outer sliding sleeve, forming an axis and sleeve fit with the horizontally arranged pipe fitting.

[0068] 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 to the first end 11 or the second end 12 of the elastic component 1, and the other end of the elastic corner connector 5 is connected to the vertical support unit 21. The two ends of the elastic corner connector 5 can undergo elastic deformation under external force; the aforementioned polymer elastic component or metal elastic component can be a leaf spring, a coil spring, etc.

[0069] The flexible corner connector 6 is a connecting chain, a connecting rope, or a connecting belt. The fixed end of the flexible corner connector 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 connector 6 passes through the connection hole of the first end 11 or the second end 12, then folds over to the fixed end and connects to the fixed end via a buckle 7 or a nylon buckle, etc., to adjust the length and tightness of the flexible corner connector 6. The flexible corner connector 6 can specifically be a chain, a rope, or a belt. The first end 11, the second end 12, and the corresponding vertical support unit 21 are all provided with corresponding rings, buckles, and other structures for the flexible corner connector 6 to pass through and connect. Utilizing the characteristics of the sling and ring connection, the flexible corner connector 6 is connected to the vertical support unit 21 via a spring, which can further improve and adjust the elastic performance of the trampoline.

[0070] In this specific embodiment, taking the elastic member 1 as a rectangular elastic plate 13 as an example, the rectangular elastic plate 13 can adopt at least one of A to E, wherein:

[0071] A flat plate with a gradually narrowing trapezoidal notch is provided between the adjacent parts of A at both ends to increase the deformation amplitude of the rectangular elastic plate 13 under elastic force;

[0072] B. The surface layer and the middle layer are made of composite panels with different material structures;

[0073] C rectangular elastic plate 13 is partially provided with longitudinal reinforcement ribs and reinforcement strips on the bottom or surface, and a reinforcement plate is provided in the middle (to avoid excessive bending in the middle);

[0074] D rectangular elastic flat plate 13 bottom with fabric pulling reinforcement net, belt

[0075] A polymer material buffer layer, a fabric buffer layer, or a pad is provided on the surface of the E rectangular elastic plate 13 in whole or in part, and a polymer material buffer bottom pad can be provided in the middle of the horizontal support unit 22 as a buffer for possible contact with the ground.

[0076] In this embodiment, a follower armrest 9 can be installed on the elastic member 1 or the vertical support unit 22 as needed. A follower stool, chair, recliner, saddle seat 8, footrest 10, bed guard, etc. can be installed on the elastic member 1 to facilitate different posture exercises, body relaxation, fitness and rehabilitation, etc. A fixed follower bed frame or a slightly larger flat plate or other structure can also be installed on the elastic members 1 of two sets of trampolines 100 to experience the undulating motion. An electronic counter or vibration sensor can also be installed on the elastic member 1, which can be displayed on the follower armrest 9, etc., to help the user understand the number of up and down movements. As shown in Figure 14, the trampoline 100 is equipped with a follower armrest 9, saddle seat 8, and footrest 10. This is an extension of the application of a vertical undulating motion device with bilateral integral elastic support elastic plates, simulating the motion of horseback riding.

[0077] The working principle of the trampoline 100 will be described in detail below by taking the example of the elastic member 1 of the trampoline 100 being a rectangular elastic plate 13 which is mounted on the vertical support unit 21 via the flexible corner connector 6 .

[0078] When the middle of the rectangular elastic plate 13 fluctuates up and down due to the pressure change of the human body, the rectangular elastic plate 13 bends and changes, and the first end 11 and the second end 12 undergo a certain symmetrical angle change. The horizontal distance between the first end 11 and the second end 12 tends to shorten. Under the traction of the connecting unit, the distance between the tops of the two groups of vertical support units 21 also tends to shorten, and the vertical support units 21 and the horizontal support units 22 undergo symmetrical elastic bending deformation, gathering elastic potential energy, and the elastic support legs 3 undergo a certain deformation. However, the middle part of the rectangular elastic plate 13 will not be obviously concave under 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, and the corresponding elastic deformation of the elastic bracket 2 also decreases or disappears, the deformation of the elastic support legs 3 decreases or disappears, the angle of the first end 11 and the second end 12 tends to reset, and the horizontal distance between the first end 11 and the second end 12 returns to its initial state. The installation position of the elastic support leg 3 is close to the inner and lower part of the bending inflection point of the elastic bracket 2, so that the elastic support leg 3 has a smaller displacement tendency when the horizontal support unit 22 bends.

[0079] It can be seen that the trampoline 100 proposed in this technical solution 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 overall elastic bracket, providing people with a vertical undulating motion device for sports training, fitness, entertainment, body relaxation and rehabilitation exercises with excellent physical feel, large rise and fall amplitude, low noise and small space.

[0080] The trampoline 100 proposed in this technical solution adopts a correct and effective method to solve the problem of how to support the elastic thin plate when the two ends supported by it are bent under force and rotated and displaced. At the same time, the bending deformation of the integral elastic bracket 2 is used to generate energy storage, so that the elastic plate undulating motion device has better elastic characteristics.

[0081] Example 2

[0082] This embodiment provides a spring system comprising multiple trampolines 100 as disclosed in the first embodiment. These trampolines 100 are supported on the bottom of a bed frame or a flat plate. For example, a fixed follower bed frame or a slightly larger flat plate or other structure can be attached to the spring elements 1 of two sets of trampolines 100 to create an undulating motion experience.
