Description

Technical Field

[0001] The utility model relates to the technical field of trampolines, in particular to a trampoline fabric and a trampoline with improved rebound efficiency. Background Art

[0002] Trampoline, also known as trampoline, refers to a competitive sport in which enthusiasts choose a bed with good elasticity and jump up to perform various movements in the air. It is a competitive sport in which athletes perform acrobatic skills by rebounding from the trampoline. It is a type of gymnastics. Trampoline is known as "aerial ballet". It uses the elastic force of the elastic bed to bounce the human body into the air, and performs various gymnastic movements and somersaults in the air. At present, many places have opened entertaining trampoline venues, and trampoline has gradually become a "net celebrity" entertainment sport. Therefore, the public is paying more and more attention to trampoline.

[0003] At present, there are many patents on trampolines, such as the authorization announcement number CN210933567 U, which discloses a composite high-strength trampoline cloth. The composite high-strength trampoline cloth can play a role of fixing and protection through the socket connection of the hard alloy positioning ring and the positioning column, and is more convenient to install. The waterproof layer and the flame retardant layer of the composite trampoline cloth can play a waterproof role and a flame retardant role respectively. The shock absorbing layer can play a buffering effect, reduce the impact on the human knee, and also enhance the elasticity. The airbag can freely compensate the high elastic mesh layer and play a shock absorbing role. However, the above trampoline cloth is basically suitable for use on higher trampolines. At present, no patents for trampolines specifically for buried planes and low-height trampolines that need to be used in conjunction with ground pits have been retrieved. Because in this application scenario, the position of the trampoline is low and basically forms a closed space with the pit. In this scenario, the wind resistance of the trampoline when vibrating increases, which will directly affect the rebound efficiency of the trampoline. Based on this, the present application discloses a trampoline with improved rebound efficiency to solve the above problems. Utility Model Content

[0004] The utility model overcomes the shortcomings of the prior art and provides a jump cloth with improved rebound efficiency, which has the functions of reducing wind resistance and improving rebound efficiency.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] Furthermore, the size of the exhaust hole is 1 to 5 mm.

[0008] Furthermore, the exhaust hole is formed by clamping two adjacent warp lines and two adjacent weft lines.

[0009] Furthermore, the warp lines and weft lines are both composed of three to eight rows of drawn wires.

[0010] Furthermore, the jump cloth body is made of polypropylene (PP) material.

[0011] Furthermore, the weft lines and the warp lines are woven crosswise up and down.

[0012] The present application seeks to protect a trampoline, comprising the above-mentioned improved jumping cloth with enhanced rebound efficiency; the trampoline comprises a frame, and the edges of the jumping cloth body are connected to the frame via springs.

[0013] Furthermore, the trampoline is an underground flat trampoline; the plane where the frame is located is level with the ground; and the four sides of the frame are overlapped on the four sides of the edge of the pit.

[0029] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0030] like Figures 1 to 7 As shown, a flop fabric with improved rebound efficiency includes a flop fabric body 1 with a sheet structure. The flop fabric body 1 includes warp threads 101 and weft threads 102. The warp threads 101 and weft threads 102 are woven alternately.

[0031] The warp lines 101 and the weft lines 102 are both composed of three to eight rows of drawn wires. The weaving method is flexible and diverse, mainly based on the cross weaving of the warp and weft lines, and can form a variety of weaving structures, which can be organized into

[0032] 3*3 / 3*4 / 3*5 / 3*6 / 3*7 / 3*8 / 4*3 / 4*4 / 4*5 / 4*6 / 4*7 / 4*8 / 5*3 / 5*4 / 5*5 / 5*6 / 5*7 / 5*8 / 6*3 / 6*4 / 6*5 / 6*6 / 6*7 / 6*8 / 7*3 / 7*4 / 7*5 / 7*6 / 7*7 / 7*8 / 8*3 / 8*4 / 8*5 / 8*6 / 8*7 / 8*8 and other different coefficients of weaving methods to meet different usage requirements; combined with the attached figure as an example, Figure 1 It is a jump cloth woven with 4×4. Figure 2 It is a jump cloth woven with 5×3 weave.

[0033] When the jumping cloth body 1 is unfolded, the space is divided into an upper area and a lower area. The advancement of the utility model lies in that the exhaust holes 2 are provided at the connection between the warp lines 101 and the weft lines 102, and the upper area and the lower area are connected by air through the exhaust holes 2; when the jumping cloth body 1 moves up and down, the air between the upper area and the lower area flows freely through the exhaust holes 2, thereby reducing the air resistance to the jumping cloth body 1; the setting of the exhaust holes 2 improves the air circulation, and the reserved exhaust holes 2 are cleverly designed to reduce the air resistance to the jumping cloth body 1, so as to achieve the purpose of improving the rebound efficiency of the trampoline.

[0034] The jump cloth body 1 is made of polypropylene (PP) material, in view of the non-toxicity, odorlessness, and excellent physical properties of polypropylene (PP) material such as strength, hardness and heat resistance.

[0035] Combination Figures 1 to 3 As can be seen, the vent hole 2 is formed by two adjacent warp lines 101 and two adjacent weft lines 102; the size of the vent hole 2 is 1 to 5 mm; Figure 3 It can be seen that the vent hole 2 is square, which can be a rectangular shape or a square shape; therefore, the size of the vent hole 2 mentioned above is 1 to 5 mm, which refers to the side length of the vent hole 2; therefore, in actual weaving, the aperture of the vent hole 2 is diversified and can be organized into

[0036] 1x1 / 1x2 / 1x3 / 1x4 / 1x5 / 2x1 / 2x2 / 2x3 / 2x4 / 2x5 / 3x1 / 3x2 / 3x3 / 3x4 / 3x5 / 4x1 / 4x2 / 4x3 / 4x4 / 4x5 / 5x1 / 5x2 / 5x3 / 5x4 / 5x5mm, but not limited to the above aperture sizes.

[0037] The size design of the above-mentioned exhaust hole 2 is based on the applicant's test. After testing, the applicant found that the optimal size range of the exhaust hole 2 is between 1 and 5 mm. If it exceeds the range of 5 mm, it will violate the safety inspection standards for the use of trampoline. If the size of the exhaust hole 2 is in the range of 0.01 to 0.99 mm, the exhaust speed cannot meet the use requirements of the product. Therefore, we take advantage of the good physical and chemical properties of polypropylene PP material and control the exhaust holes within the size range of 1 to 5 mm through weaving methods. This design not only ensures the exhaust efficiency, but also avoids the problems of loose yarn and hole deformation. For trampolines, exhaust holes 2 of 1 to 5 mm can increase the exhaust speed.

[0038] As another weaving method, the weft lines 102 and the warp lines 101 are woven in an up-and-down cross pattern. Figure 3 As shown, the jump cloth body 1 is made of 7×7 up and down weaving. The so-called up and down weaving refers to Figure 3 The structure has a weft line 102 and a warp line 101 each having 7 drawing wires, 4 of which are exposed on the upper surface of the jump cloth body 1, and the other 3 are exposed on the lower surface of the jump cloth body 1. This weaving method can effectively enhance the bite of each warp and weft line, and further enhance the overall strength of the mesh.

[0039] The utility model also seeks to protect a trampoline, comprising any of the above-mentioned improved trampoline fabrics with enhanced rebound efficiency; the edges of the trampoline fabric body 1 are connected to the frame 3 via springs.

[0040] Figure 5 It is one embodiment of a trampoline. In this embodiment, the trampoline is an underground flat trampoline used in conjunction with a pit. The plane where the frame 3 is located is level with the ground. The periphery of the frame 3 is overlapped with the periphery edge of the pit.

[0041] Figure 6 It is one embodiment of a trampoline. In this embodiment, the trampoline is a short trampoline used in conjunction with a pit. The plane where the frame 3 is located is higher than the ground. The edges of the frame 3 are connected with legs 4. The diameter of the frame 3 is larger than the diameter of the pit, and the legs 4 are located outside the edges of the pit.

[0042] The above two structures are both used in conjunction with the pits. Since the air in the pits is relatively closed, if a conventional jump cloth is used, when the jump cloth moves downward, it will squeeze the air in the pits, forming a large resistance and poor resilience. However, the jump cloth body 1 with exhaust holes 2 in the present application can quickly release the air, effectively reduce the resistance of the jump cloth to the airflow, and maintain a high rebound efficiency.

[0043] Figure 7It is one of the embodiments of a trampoline. In this embodiment, the trampoline is a high trampoline and is not used in conjunction with a pit. The trampoline is supported on flat ground by legs 4 and its application scenario is the same as that of a conventional trampoline. However, since the trampoline body 1 has exhaust holes 2, its rebound efficiency is also higher than that of a conventional trampoline.

[0044] At that time, the exhaust hole 2 not only has an exhaust function, but also has a drainage function, which can make the moisture falling to the surface of the jump cloth body 1 fall down through the exhaust hole 2 and will not accumulate on the surface of the jump cloth body 1.

[0045] like Figure 8 The figure is a schematic diagram of the test method of the trampoline of the embodiment of the utility model, which is a test of the buried flat trampoline; during the test, a ball weighing 75 kg falls freely from a specific height, compresses the trampoline body 1 and rebounds. The highest rebound height of the ball is captured by a camera and measured by a measuring ruler. The test results are as follows:

[0046]

[0047] By testing the rebound effect of trampolines with different apertures, the data show that the use of 2x2mm pore size exhaust holes not only improves the exhaust and drainage performance, but also achieves a higher rebound effect than trampolines with an aperture of 0.8x0.8mm, with an increase of 26-36%.

[0048] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
