Description

Technical Field

[0001] This utility model relates to the field of artificial turf technology, specifically to a heat-melting type artificial turf for tennis courts. Background Technology

[0002] Artificial turf is an essential facility in tennis courts, providing cushioning and protection for athletes. In tennis, athletes need to move quickly, stop abruptly, and change direction. These actions generate strong friction and shear forces on the ground. The soles of tennis shoes, especially hard-soled shoes, typically wear down the durable rubber or treads, causing wear and tear on the turf surface over time. Furthermore, the bounce height and speed of the tennis ball are crucial to the fairness of the game; therefore, the turf must be highly durable to prevent uneven surfaces caused by localized wear, which could lead to irregular bounces of the tennis ball and affect the quality of the match.

[0003] In the existing technology, the hot-melt type artificial turf used for tennis courts is produced by a special manufacturing process that tightly bonds grass fibers, base fabric and non-woven fabric together to form a polymer composite. This process improves the integrity and stability of the artificial turf, but due to the high degree of bonding, the overall water-draining effect of the turf is poor and the water-draining space is small, which means there is room for technological improvement. Utility Model Content

[0004] This invention aims to solve the aforementioned technical problems of poor overall water drainage effect and small water drainage space in artificial turf, and provides a heat-melting type artificial turf for tennis courts.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a hot-melt type artificial turf for tennis courts, comprising a bottom layer, a base fabric, a woven layer, and a grass fiber structure; adjacent bottom layers can be spliced ​​together for installation;

[0006] A water-guiding structure is provided between the bottom layer and the base fabric. The water-guiding structure includes several longitudinal hollow rods and several transverse hollow rods. Water inlet holes are arranged on the longitudinal hollow rods and transverse hollow rods. A cross-shaped connector is detachably provided at the intersection of the ends of the longitudinal hollow rods and transverse hollow rods. The connector is hollow inside and its ends are all through.

[0007] The grass fiber structure includes bent grass fibers, and curved grass fibers are wrapped around the outside of the bent grass fibers.

[0008] Furthermore, the bottom layer is provided with anti-slip texture.

[0009] Furthermore, the bottom layer has several serrated inserts on its left and front sides, and serrated slots that can accommodate the inserts on its rear and right sides.

[0010] Furthermore, the inner bottom surface of the connector end is provided with a support rod, the upper end of the support rod is rotatably provided with a limiting strip, and the upper surface of the connector end is provided with a limiting groove I that can accommodate the limiting strip; the ends and upper and lower sides of the longitudinal hollow rod and the transverse hollow rod are provided with limiting groove II that can accommodate the limiting strip.

[0011] Furthermore, a reinforcing plate is provided between the bottom layer and the base fabric, and between the longitudinal hollow rods and the transverse hollow rods. The reinforcing plate is provided with through holes that can accommodate the grass fiber structure.

[0012] Furthermore, the grass fiber structure extends into a woven layer, a base fabric, and a reinforcing plate, and is then heat-melted and shaped.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] Crossing horizontal and vertical hollow rods are added between the base fabric and the bottom layer, and the adjacent turf modules are connected by hollow connectors. This allows water to be stored in the horizontal and vertical hollow rods, which can flow freely when there is a lot of water, making it less likely to accumulate. This has a good water-conducting effect and can reduce the water accumulation under the grass fibers.

[0015] It features serrated inserts and slots, making it difficult for adjacent turf modules to detach under stress, making it suitable for tennis courts and providing strong stability. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Example 1, in conjunction with Appendix Figure 1 A type of hot-melt artificial turf for tennis courts includes a base layer 1, a base fabric 2, a woven layer 3, and a grass fiber structure 4; the base layer 1 has anti-slip textures on the bottom to increase the friction between the base layer 1 and the ground during use, thereby improving anti-slip properties;

[0024] Combined with appendix Figure 1 , 2 The adjacent bottom layer 1 can be spliced ​​and installed; specifically, the left and front sides of the bottom layer 1 are provided with several serrated inserts 5, and the rear and right sides of the bottom layer 1 are provided with serrated slots that can accommodate the inserts 5; through the serrated inserts and slots, the adjacent lawn modules are not easy to detach when subjected to force, which is suitable for tennis courts and has strong stability.

[0025] Combined with appendix Figure 1 , 2 3, 4, 5. A water-guiding structure is provided between the bottom layer 1 and the base fabric 2. Specifically, the water-guiding structure includes several longitudinal hollow rods 6 and several transverse hollow rods 7. Water inlet holes 8 are arranged on the longitudinal hollow rods 6 and transverse hollow rods 7. When rainwater seeps into the interior along the grass fiber structure 4, it will enter the longitudinal hollow rods 6 and transverse hollow rods 7 through the water inlet holes 8. When the water volume is large, it will flow on its own inside the longitudinal hollow rods 6 and transverse hollow rods 7, which can reduce the water accumulated under the grass fiber and prevent athletes from slipping due to insufficient foot friction during use. A cross-shaped connector 9 is detachably provided at the intersection of the ends of the longitudinal hollow rods 6 and transverse hollow rods 7. The connector 9 is hollow inside and its ends are all through.

[0026] Based on the above structure, a support rod 10 is provided on the inner bottom surface of the end of the connector 9, and a limiting strip 11 is rotatably provided on the upper end of the support rod 10. A limiting groove 12 that can accommodate the limiting strip 11 is provided on the upper surface of the end of the connector 9. A limiting groove 2 13 that can accommodate the limiting strip 11 is provided on the end and upper and lower sides of the longitudinal hollow rod 6 and the transverse hollow rod 7. Thus, when connecting the longitudinal hollow rod 6 and the transverse hollow rod 7 through the connector 9, the limiting strip 11 is inserted into the limiting groove 2 13, and then extends out of the corresponding limiting groove 12. After rotation to form a limit, the installation and fixation of the longitudinal hollow rod 6 and the transverse hollow rod 7 can be completed. It is worth mentioning that the length of the support rod 10 should be limited to only be able to pass through the limiting groove 12. Thus, after the limiting strip 11 is rotated, its bottom surface is squeezed and rubbed against the top surface of the connector 9, making it difficult for it to rotate on its own.

[0027] Combined with appendix Figure 3A reinforcing plate 14 is provided between the bottom layer 1 and the base fabric 2, and between the longitudinal hollow rod 6 and the transverse hollow rod 7. The reinforcing plate 14 has through holes 15 that can accommodate the grass fiber structure 4. The reinforcing plate 14 provides additional support and prevents the grass fiber structure 4 from collapsing due to the space between the longitudinal hollow rod 6 and the transverse hollow rod 7. The grass fiber structure 4 extends from the woven layer 3, the base fabric 2, and the reinforcing plate 14 and is heat-fused and shaped.

[0028] In addition, the grass fiber structure 4 includes bent grass fibers, with curved grass fibers wrapped around the outside of the bent grass fibers. Compared with straight grass fibers, the bent grass fibers themselves have more turning points and friction. The curvilinear grass fibers can further increase the friction and provide additional support for the bent grass fibers, making them less prone to collapse.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
