Description

Impact-resistant and shock-proof structure

This case is about an impact-resistant and shock-proof structure, specifically a floor mat structure used to prevent subsidence, vibration and noise during exercise.

In recent years, sports or fitness have become popular. People who love sports or fitness may engage in intense exercise at home or in the gym, or use fitness equipment to keep fit. However, intense running and jumping can cause floor vibrations or noise, affecting the peace of neighbors (especially those living downstairs). On the other hand, when using fitness equipment to strengthen your body, the fitness equipment may also cause the floor to vibrate or produce noise. Especially during weight training, after lifting the barbell, you usually let it go when it is a certain distance from the floor, causing the barbell to fall freely. The ground directly hits the floor, causing great vibrations and noise on the floor. This phenomenon will not only damage the floor, but also seriously affect the peace of neighbors. Therefore, buffer materials need to be laid on the floor to reduce noise and floor vibration. Commonly used shock-absorbing materials in the industry include rubber floor mats, high-density foam, honeycomb deconstructed floor mats, etc. However, these shock-absorbing materials are too soft, so when the athlete's feet step on them, the shock-absorbing materials will sink, thus affecting the smooth progress of the movement. On the other hand, when the barbell falls freely on the shock-absorbing material, the shock-absorbing material sinks deeper and still cannot completely eliminate the vibration and noise caused by the barbell hitting the floor. In order to solve the above-mentioned problems of subsidence, vibration, noise, etc., an impact-resistant and shock-proof structure that is both rigid and flexible is needed, and this structure can be easily and conveniently installed in various situations.

Therefore, one of the purposes of this case is to provide an impact-resistant and shock-proof structure that makes little noise and vibration when it is impacted, and is not easy to break. Therefore, this case provides an impact-resistant and shock-proof structure, which includes in the vertical direction: the first shock-absorbing layer is composed of multiple pieces of shock-absorbing materials that are separated from each other and arranged at intervals; the second shock-absorbing layer is composed of multiple pieces of shock-absorbing materials that are separated from each other and arranged at intervals. The material is composed of or composed of a whole piece of shock-absorbing material, so that each piece of the plurality of shock-absorbing materials constituting the second shock-absorbing layer or the whole piece of shock-absorbing material is in the upright direction and the first shock-absorbing layer constituting the At least two of the plurality of shock-absorbing materials at least partially overlap; and at least two buffer layers are respectively provided above and below the first shock-absorbing layer and the second shock-absorbing layer. Each layer of the buffer layers is composed of an entire piece. Made of cushioning material. Preferably, the impact-resistant and shock-proof structure further includes a third shock-absorbing layer, which is composed of a whole piece of shock-absorbing material and is disposed below the second shock-absorbing layer. Preferably, the impact-resistant and shock-proof structure further includes sound-insulating cotton, which is disposed in the gaps between the multiple pieces of shock-absorbing materials. Preferably, the impact-resistant and shock-proof structure further includes a mesh layer disposed below the third shock-absorbing layer. Preferably, the lower surface of the mesh layer is in close contact with one of the buffer layers. Preferably, the impact-resistant and shock-proof structure further includes a base layer, which is the bottom layer of the impact-resistant and shock-proof structure and has the function of supporting or stabilizing. Preferably, the upper surface of each shock-absorbing layer is in close contact with one of the buffer layers. Preferably, the material of each shock-absorbing layer is selected from the group consisting of rigid shock-absorbing materials such as wood, metal, fiberboard, composite materials, hard rubber, and plastic rubber. Each shock-absorbing layer can be made of the same material, or it can be Use different materials. Preferably, the material of each buffer layer can be selected from the group consisting of rubber, resin, foam materials, polymers, glass wool, polyester cotton, foam, cork, plastic, composite materials and other elastic buffer materials. Group, each buffer layer can use the same material or different materials. Preferably, the layers are adhered and fixed by adhesive. The advantages of this case compared to the prior art have been described above for each of the purposes. Those familiar with this technology can better understand other benefits and other purposes of this case as defined in the claims after reading the description.

The foregoing and other technical contents, features and functions of this case will be clearly understood in the following detailed description with reference to the drawings and preferred embodiments. As shown in Figures 1 and 2, the first preferred embodiment of the impact-resistant and shock-proof structure 100 of this case may include, in the vertical direction V, sequentially or non-sequentially: a first buffer layer 1, a first shock-absorbing layer 2, a second Buffer layer 3, second shock-absorbing layer 4, third buffer layer 5, third shock-absorbing layer 6, mesh layer 7, fourth buffer layer 8, and base layer 9. Adhesive can be optionally used between each adjacent layer to adhere and fix it. In the following, the term “buffer layer” may generally refer to all or one of the first to fourth buffer layers 1 to 8 . The term "shock-absorbing layer" can generally refer to all or one of the first shock-absorbing layer 2 to the third shock-absorbing layer 6 . The material of each buffer layer can be selected from the group consisting of rubber, resin, foam materials, polymers, glass wool, polyester cotton, foam, cork, plastic, composite materials and other elastic buffer materials. The materials of each buffer layer may be the same or different. The material of each shock-absorbing layer can be selected from the group consisting of rigid shock-absorbing materials such as wood, metal, fiberboard, composite materials, hard rubber, and plastic rubber. The materials of each shock-absorbing layer may be the same or different. When a certain shock-absorbing layer is made of a material with higher strength, the thickness of this layer will be thinner, and the overall thickness of the impact-resistant and shock-proof structure 100 will also be thinner. The first buffer layer 1 is a large piece of complete buffer material (such as foam), which is used to directly contact the impact source or force source [such as the human body or fitness equipment (such as barbells)] to initially absorb the impact force. The first shock-absorbing layer 2 is made of a plurality of separate plate-shaped shock-absorbing materials (such as wooden boards) arranged in a matrix shape with small spacing. The gaps between each piece of shock-absorbing material can be selectively filled or adhered with sound-insulating cotton (not shown) to reduce the volume generated when the plate-shaped shock-absorbing material is impacted. Each piece of shock-absorbing material can be adhered to the first buffer layer 1 and/or the second buffer layer 3 to maintain a fixed distance between each piece of shock-absorbing material. When the impact force is transmitted from the first buffer layer 1 to one of the plate-shaped shock-absorbing materials of the first shock-absorbing layer 2, this small piece of plate-shaped shock-absorbing material can change its posture (for example, one end tilts downward and the other end rises), instead of It is bent by the impact force, so compared with a large complete piece of shock-absorbing material that is difficult to change its posture, the small piece of plate-shaped shock-absorbing material in this embodiment is less likely to break. The second buffer layer 3 is similar to the first buffer layer 1 and is composed of a large piece of complete buffer material, which is used to slightly disperse the impact force of the first shock-absorbing layer 2 in a small area to the entire second buffer layer 3 in a large area. The materials of the second buffer layer 3 and the first buffer layer 1 may be the same or different. The second shock-absorbing layer 4 is composed of a plurality of separate plate-shaped shock-absorbing materials (for example, metal plates) 41 arranged in a matrix shape with small spacing. The gaps between each plate-shaped shock-absorbing material 41 can be filled or adhered with sound insulation cotton 42 to reduce the sound volume generated when the plate is impacted. Each piece of shock-absorbing material 41 can also be adhered to the second buffer layer 3 and/or the third buffer layer 5 to maintain a fixed distance between each piece of shock-absorbing material 41 . It is worth special attention that: as shown in Figure 3, each plate-shaped shock-absorbing material 41 of the second shock-absorbing layer 4 is disposed at the intersection of four adjacent shock-absorbing materials of the first shock-absorbing layer 2, and preferably the first shock-absorbing layer 4 The intersection point of the cross-shaped gaps between the four adjacent pieces of shock-absorbing materials on layer 2 is located at the center point of a piece of shock-absorbing material 41 of the second shock-absorbing layer 4; in other words, a piece of shock-absorbing material 41 of the second shock-absorbing layer 4 is in the vertical direction V Aim at the center of the plane formed by four adjacent pieces of shock-absorbing materials of the first shock-absorbing layer 2. The above-mentioned arrangement of the relative positions of the first shock-absorbing layer 2 and the second shock-absorbing layer 4 is because one piece of shock-absorbing material 41 of the second shock-absorbing layer 4 and four pieces of shock-absorbing materials of the first shock-absorbing layer 2 partially overlap, so the first shock-absorbing layer 2 can be The impact force borne by a piece of shock-absorbing material in layer 2 is dispersed to the four pieces of shock-absorbing material 41 in the second shock-absorbing layer 4, so that the force-bearing area changes from small to large. Therefore, on the one hand, the stressed shock-absorbing material is not easy to break, and on the other hand, the force can be reduced. The volume produced by the impact. In another embodiment, a piece of shock-absorbing material of the second shock-absorbing layer 4 is disposed between two adjacent pieces (as shown in Figure 5) or six adjacent pieces (as shown in Figure 4) of the first shock-absorbing layer 2. The central position of the composed plane. In another embodiment, the second shock-absorbing layer 4 can be a large piece of complete shock-absorbing material, and this large piece of complete shock-absorbing material overlaps at least partially with all the small pieces of shock-absorbing material in the first shock-absorbing layer 2 . The third buffer layer 5 is similar to the second buffer layer 3 and is composed of a large piece of complete buffer material, which redistributes the impact force of the small area of the second shock-absorbing layer 4 to the entire third buffer layer 5 of a large area. The materials of the first, second and third buffer layers may be the same or different. The third shock-absorbing layer 6 can be composed of a large piece of complete shock-absorbing material (such as wood), which redistributes the impact force transmitted from the second shock-absorbing layer 4 and the third buffer layer 5 to the entire piece of shock-absorbing material, so that the impact force per unit area is The impact force endured becomes smaller, so the third shock-absorbing layer 6 will not be partially broken. On the other hand, because the third shock-absorbing layer 6 is a large piece of complete shock-absorbing material, compared with the small pieces of shock-absorbing material in the first shock-absorbing layer 2 and the second shock-absorbing layer 4, the third shock-absorbing layer 6 is less likely to change when it is stressed. posture, so there will be no significant sagging. The mesh layer 7 is, for example, a nylon mesh, which is used to reinforce the third shock-absorbing layer 6 so that the third shock-absorbing layer 6 is not easily damaged and spread out. The fourth buffer layer 8 is similar to the third buffer layer 5 and is composed of a large piece of complete buffer material for absorbing the entire impact force transmitted from the third shock-absorbing layer 6 . The materials of the first, second, third and fourth buffer layers may be the same or different. The base layer 9 may be, for example, expanded polyethylene (EPE). ), which is padded under the fourth buffer layer 8 as the bottom layer of the impact-resistant and shock-proof structure 100. When the impact point is located at the edge area of the first buffer layer 1, there may not necessarily be the shock-absorbing material 41 of the second shock-absorbing layer 4 directly below the edge area, so the eight layers of materials mentioned above may be slightly displaced in the horizontal direction. However, because foam cloth is harder than foam and has high toughness, it can be used to stably support the eight layers of materials mentioned above. In other embodiments, the base layer 9 may also be omitted. Other embodiments When the second shock-absorbing layer 4 is a large piece of complete shock-absorbing material, the third shock-absorbing layer 4 and the fourth buffer layer 8 can be omitted, or even the mesh layer 7 can be omitted. At this time, the second shock-absorbing layer 4 also has the function of the third shock-absorbing layer 6, which is "less likely to change its posture when receiving force, so it will not sink significantly", and the third buffer layer 5 has the "absorption function" similar to that of the fourth buffer layer. The entire surface impact force transmitted from the second shock-absorbing layer 4" function. When the second shock-absorbing layer 4 includes a plurality of small plate-shaped shock-absorbing materials 41, the positions of the second shock-absorbing layer 4 and the first shock-absorbing layer 2 can be interchanged. However, if the second shock-absorbing layer 4 is composed of a whole piece of large shock-absorbing material, the positions of the second shock-absorbing layer 4 and the first shock-absorbing layer 2 cannot be interchanged. If the third shock-absorbing layer 6 is a wooden board, in order to prevent the wooden board from spreading when it breaks, the mesh layer 7 needs to be used together. If the third shock-absorbing layer 6 is a metal plate, there is no need to use the mesh layer 7 because the metal plate will not spread out when broken. effect In this case, at least one shock-absorbing layer is composed of multiple plate-shaped rigid shock-absorbing materials arranged at intervals, and the place where the impact source (such as the human body or sports equipment) hits the shock-absorbing layer is usually just a point or a small area, so it only hits the On a small piece of plate-like shock-absorbing material of the shock-absorbing layer or on the adjacent area of two adjacent small pieces of plate-like shock-absorbing material. At this time, because the area of the plate-shaped shock-absorbing material or the two adjacent plate-shaped shock-absorbing materials is small, its posture can be easily changed, for example, one end can sink and the other end can move up. The piece of plate-shaped shock-absorbing material or the two adjacent pieces of plate-shaped shock-absorbing material itself is not bent or deformed, so it is not easy to break. On the other hand, if the shock-absorbing layer is a large piece of rigid shock-absorbing material, when the impact source hits a point in the shock-absorbing layer, the large piece of rigid shock-absorbing material will not easily change its posture, so that the impact point will move relative to the surrounding area. Bending deformation occurs in the area, which easily causes the shock-absorbing layer to rupture. Furthermore, in this case, a buffer layer and another shock-absorbing layer are provided below the shock-absorbing layer composed of multiple small pieces of shock-absorbing materials, allowing the large impact force suffered by the upper layer of small shock-absorbing materials to be dispersed to a larger area below. layer, the impact force per unit area of the lower layer is greatly reduced, so the lower layer has less noise and is not easy to break. Especially when the other shock-absorbing layer is also composed of multiple small pieces of shock-absorbing material, because one small piece of shock-absorbing material of the upper shock-absorbing layer is arranged adjacent to two/four/six pieces of small shock-absorbing materials of the lower shock-absorbing layer The central area of the shock-absorbing layer below, so on the one hand, the adjacent two/four/six pieces of small shock-absorbing materials on the lower shock-absorbing layer can easily change their posture and are not easy to break; The large impact force is dispersed to the adjacent two/four/six pieces of smaller shock-absorbing materials on the lower shock-absorbing layer. The stress-bearing area becomes larger, and the impact force per unit area becomes smaller, so the vibration and noise become smaller. Use status The above-mentioned impact-resistant and earthquake-proof structure 100 can be laid layer by layer on the floor or in places that need to be earthquake-proof. In addition, as shown in Figure 6 , the impact-resistant and shock-proof structure 100 of this case can additionally include a hollow U-shaped shell 10 with an opening on one side, for the above-mentioned layers of materials to be laid layer by layer in the shell 10 to facilitate the installation of the shell 10 Move and place materials where needed with each layer of materials. To sum up the above, the impact-resistant and shock-proof structure 100 of this case can indeed achieve the purpose of this case because at least one shock-absorbing layer is composed of multiple small pieces of shock-absorbing materials, and multiple layers of buffer layers and shock-absorbing layers are stacked alternately. However, the above are only preferred embodiments of this case, and should not be used to limit the scope of implementation of this case. That is, any simple equivalent changes and modifications made based on the scope of the patent application and the content of the specification in this case should still be included in the scope of the application. Within the scope covered by the patent in this case.
