Description

Technical Field

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

[0002] Gateball is an outdoor ball game played on a lawn using mallets to hit a ball through iron ring gates. It originated in France. A game typically involves two teams of five players each. Points are scored by hitting the ball through the gates and touching it. The first team to reach a maximum score of 25 points within 30 minutes wins. The modern standard court is rectangular, with six iron ring gates and one marker, and wooden clubs are used. Gateball improves coordination, flexibility, and reaction time. Hitting the ball requires hand-foot coordination, and movement demands quick reflexes. It also enhances cardiovascular function and promotes blood circulation.

[0003] Artificial turf used for gateball courts has specific technical requirements. The grass fibers must be soft, comfortable, and wear-resistant, often using curved fibers to increase friction with the feet during play and improve safety. In existing technology, modular artificial turf is primarily assembled by interlocking. To enhance the strength of the joints, some are glued together. However, in actual use, due to adhesive aging, the joints are prone to warping, affecting both usability and aesthetics. Furthermore, existing artificial turf for gateball courts often uses rubber granules to improve slip resistance and wear resistance. However, in practice, excessive use of freely movable rubber granules can increase ball friction, causing problems. Therefore, there is room for technological improvement. Utility Model Content

[0004] This invention aims to solve the problems mentioned above, such as the tendency for artificial turf joints to curl up due to adhesive aging, and the increased friction of the ball caused by excessive filling of freely movable rubber granules. The invention provides a hot-melt type artificial turf for gateball 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 gateball courts, including a base layer; characterized in that: a splicing structure is provided between adjacent base layers, the splicing structure including a splicing strip one provided on the front side and left side of the base layer near the lower end, and a splicing strip two provided on the rear side and right side of the base layer near the upper end;

[0006] An installation layer is bonded to the base layer, and a grass fiber limiting structure is provided between the installation layer and the base layer; the grass fiber limiting structure includes hollow truncated cones arranged on the base layer, and a through groove corresponding to the hollow truncated cones on the base layer; the hollow truncated cones are made of rubber and have an installation hole at their upper end; the installation layer has a through hole that can accommodate the hollow truncated cones.

[0007] The mounting hole is provided with a grass fiber assembly, which includes an outer sleeve, an inner sleeve fixed to the upper end of the outer sleeve, bent grass fibers on the inner sleeve, and upright grass fibers on the outer sleeve and along the outer periphery of the inner sleeve.

[0008] A waterproof base fabric is provided beneath the base layer.

[0009] Furthermore, the bottom surface of the second splicing strip is uniformly arranged with limiting blocks, and the first splicing strip is provided with limiting grooves that can accommodate the corresponding limiting blocks.

[0010] Furthermore, the through hole is located at the middle of the outer side of the hollow frustum and is in contact with it by compression.

[0011] Furthermore, the outer surface of the outer sleeve is bonded to the mounting hole.

[0012] Furthermore, the height of the upright grass fibers is less than that of the bent grass fibers.

[0013] Furthermore, the lower end of the outer sleeve extends sequentially to form mounting holes, a through groove in the base layer, and is bonded to the waterproof backing fabric.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] With the connecting strips one and two that come with the base fabric, as well as the corresponding limiting blocks and limiting grooves, adjacent base fabrics can be quickly spliced ​​together, limiting each other and preventing edge curling or rolling, thus reducing maintenance difficulty.

[0016] The grass fibers consist of taller, bent grass fibers located in the middle and shorter, upright grass fibers located around the perimeter. The bent grass fibers are used to increase friction and increase the contact area, while the upright grass fibers ensure the overall structural strength of the grass fibers and reduce the possibility of the grass fibers collapsing.

[0017] A hollow frustum made of rubber is used instead of a rubber ball. This provides friction during movement and reduces the impact of a large number of freely rolling rubber balls on the ball's rolling motion. Based on this, through holes and mounting layers are used to support and restrict the hollow frustum, preventing it from breaking after long-term use and affecting its support for the grass fibers.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Example 1, in conjunction with Appendix Figure 1 , 3 4. A type of hot-melt artificial turf for gateball courts, comprising a base layer 1; a splicing structure is provided between adjacent base layers 1, specifically, the splicing structure includes a splicing strip 1 2 provided on the front side and left side of the base layer 1 near the lower end, and a splicing strip 2 3 provided on the rear side and right side of the base layer 1 near the upper end; the thickness of splicing strip 1 2 and splicing strip 2 3 is half that of the base layer 1, which reduces the discomfort underfoot caused by height difference after splicing;

[0026] Based on the above structure, the bottom surface of splicing strip 2 3 is evenly arranged with limiting blocks 4, and splicing strip 1 2 is provided with limiting grooves 5 that can accommodate the corresponding limiting blocks 4; the limiting blocks 4 and limiting grooves 5 can improve the stability of splicing splicing strip 1 2 and splicing strip 2 3, making them less likely to separate.

[0027] Combined with appendix Figure 1 , 2 3, 4. An installation layer 6 is bonded to the base layer 1, and a grass fiber limiting structure is provided between the installation layer 6 and the base layer 1. Specifically, the grass fiber limiting structure includes hollow frustums 7 arranged on the base layer 1, and through grooves corresponding to the hollow frustums 7 on the base layer 1 to facilitate the extension of grass fibers. The hollow frustums 7 are made of rubber, and their upper ends are provided with installation holes 8. By using the hollow frustums 7 instead of rubber balls, on the one hand, friction is provided during movement, and on the other hand, the influence of a large number of freely rolling rubber balls on the rolling of the ball during movement is reduced. At the same time, it can also provide fixation and support for the grass fibers. The installation layer 6 is provided with through holes 9 that can accommodate the hollow frustums 7. The through holes 9 are located at the middle of the outer side of the hollow frustums 7 and are in pressure contact with them. Through the installation layer 6 and several through holes 9, support can be formed on the outer side of the hollow frustums 7 to prevent the hollow frustums 7 from cracking or being damaged under long-term pressure and trampling.

[0028] Combined with appendix Figure 1 , 25. A grass fiber assembly is provided in the mounting hole 8. Specifically, the grass fiber assembly includes an outer sleeve 10, the outer side of which is bonded to the mounting hole 8 to ensure the overall firmness of the grass fiber assembly. An inner sleeve 11 is fixed to the upper end of the outer sleeve 10. The inner sleeve 11 is provided with bent grass fibers 12, and the outer sleeve 10 is provided with upright grass fibers 13 along the outer periphery of the inner sleeve 11. The height of the upright grass fibers 13 is less than that of the bent grass fibers 12. Thus, the higher bent grass fibers 12 contact the feet first, which can increase the contact area, improve friction, and make it less likely to slip. The lower upright grass fibers 13 ensure the overall structural strength of the grass fiber and reduce the possibility of the grass fiber collapsing under stress.

[0029] In addition, a waterproof backing fabric 14 is provided under the base layer 1; the lower end of the outer sleeve 10 extends out the mounting hole 8 and the through groove of the base layer 1 in sequence and is bonded to the waterproof backing fabric 14; it is fixed by hot melt composite adhesive technology to improve the firmness of the bond between the grass fibers and the waterproof backing fabric 14, and the waterproof performance can prevent the lawn from bulging due to water absorption and evaporation of ground air; a polyethylene film can be attached to the bottom surface of the waterproof backing fabric 14 to improve the waterproof performance on the basis of hot melt adhesive.

[0030] 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.
