Description

Technical Field

[0001] This utility model relates to the field of buffer structures, specifically to a ground buffer structure. Background Technology

[0002] With increasing societal concern for children's play safety, the design and management of outdoor play areas has become a crucial issue. In the past, many play areas were constructed simply by laying gravel on the excavated ground as a cushioning material; however, this approach did not provide truly effective protection and could even introduce additional risks and maintenance costs. Therefore, selecting appropriate play area materials to ensure children's safety during play is of paramount importance.

[0003] The ground paving material is chosen because it is relatively inexpensive and readily available. However, this approach has drawbacks such as a lack of effective cushioning, increased hazard due to gravel spraying, and high maintenance costs.

[0004] While gravel has some looseness, it cannot effectively absorb impact when subjected to force. When children fall from play equipment (such as swings, climbing frames, or slides), the cushioning effect of the gravel layer is extremely limited, which may lead to abrasions, bruises, or even more serious injuries such as fractures.

[0005] Furthermore, when children run, jump, or play in the playground, gravel is often kicked out of the area and even splashes onto the bottom of play equipment, causing the original cushioning layer to thin or disappear. This increases the depth of the play pit, making it easier for children to get injured when they fall in. In addition, gravel scattered outside the playground may also pose a potential danger to children in other play areas or passersby.

[0006] Because the gravel area is 30 to 35 centimeters deep, and the gravel washes away over time, it needs to be replenished regularly to maintain an appropriate cover thickness. However, this not only increases the workload of site management but also incurs additional maintenance costs. In the long run, this approach is relatively uneconomical and does not align with the concept of sustainable development for modern playgrounds. Utility Model Content

[0029] Before this utility model is described in detail, it should be noted that similar components and parts are represented by the same numbers in the following description.

[0030] See Figures 1 to 3 As shown, the first embodiment of this utility model provides a ground buffer structure, which mainly consists of a frame 10 and a plurality of buffer cylinders 20, wherein:

[0031] The frame 10 has a rectangular frame portion 11 and a plurality of through holes 12 disposed within the frame portion 11; in this embodiment, each of the through holes 12 is circular, but not limited thereto; in addition, the frame 10 also has a plurality of reinforcing ribs 13 arranged laterally and longitudinally on the frame portion 11 and located between each of the through holes 12, thereby improving the structural strength of the frame portion 11 and each of the through holes 12; next, refer to Figure 6A and Figure 6BAs shown, the frame 10 also has a plurality of recesses 14 and protrusions 15 provided on the frame portion 11. The recesses 14 of the frame 10 are secured by the protrusions 15 of another frame 10, and the protrusions 15 of the frame 10 are used to secure the recesses 14 of another frame 10. After the recesses 14 and the protrusions 15 are secured to each other, a positioning member 16 can be inserted between the recesses 14 and the protrusions 15, thereby firmly connecting the spliced ​​frames 10.

[0032] Each buffer cylinder 20 is independently disposed on the frame 10, and each has a circular force-receiving ring portion 21, a plurality of buffer ribs 22, and a buffer space 23 defined by the force-receiving ring portion 21 and each of the buffer ribs 22 and communicating with the through hole 12. In this embodiment, each buffer cylinder 20 and the frame 10 are integrally molded from plastic material, but this is not a limitation, and they can also be made of materials such as plastic steel or metal. The following description focuses on a single buffer cylinder 20.

[0033] The force-bearing ring 21 of the buffer cylinder 20 is located above the through hole 12 of the frame 10 and is a distance away from the through hole 12. The force-bearing ring 21 has a circular through hole 211 that communicates with the buffer space 23. In addition, the ring diameter of the force-bearing ring 21 is smaller than the hole diameter of the through hole 12 of the frame 10.

[0034] Each of the buffer ribs 22 of the buffer cylinder 20 is longitudinally arranged between the force-bearing ring portion 21 and the through hole 12, and each has a first end 221 located at the edge of the through hole 12 and a second end 222 located opposite to the first end 221 and located at the force-bearing ring portion 21, and each buffer rib 22 gradually expands outward from the force-bearing ring portion 21 toward the frame 10; in addition, each buffer rib 22 is equally spaced and arranged in a ring around the through hole 12, and every two adjacent buffer ribs 22, the force-bearing ring portion 21 and the edge of the through hole 12 jointly define an opening 24 communicating with the buffer space 23; in this embodiment, the opening 24 is rectangular, but not limited thereto.

[0035] The above describes the configuration of the main components of the first embodiment of this utility model. The usage and effects of this utility model are explained below.

[0036] See also Figure 4As shown, when the gravel area 30 of the outdoor playground is being constructed, a trench 31 is first dug out, then a layer of non-woven fabric 41 is laid in the trench 31, and then the ground buffer structure of this utility model is placed on it, with the frame 10 placed on the bottom surface of the trench 31 and the force-bearing ring 21 of each buffer cylinder 20 adjacent to the opening of the trench 31; then gravel 50 is poured in, so that the gravel 50 is not only located in the ground buffer structure and inside the trench 31, but also inside the buffer space 23 of each buffer cylinder 20. Accordingly, through the design of the force-bearing ring 21, multiple buffer ribs 22, buffer space 23 and opening 24 on the buffer cylinder 20, when the player steps on the gravel area, the stepping force will be resisted by the force-bearing ring 21 and each of the buffer ribs 22, so as to improve the shock absorption capacity; at the same time, the gravel 50 inside and outside each buffer cylinder 20 will be restricted by the structural design of the buffer cylinder 20, thereby stabilizing the gravel 50 in the gravel area 30, effectively maintaining the flatness of the surface of the gravel area 30, improving the buffering effect, reducing gravel spraying, reducing maintenance costs, or improving the safety of the gravel area.

[0037] It is worth mentioning that, because the ground buffer structure of this utility model is embedded in the pit 31 of the gravel area 30, and the frame 10 is positioned below and each buffer cylinder 20 is positioned above, the possibility and danger of digging up hidden objects, such as sharp objects, are effectively reduced. In addition, after the ground buffer structure of this utility model is embedded in the pit 31 of the gravel area 30, the depth of the pit 31 only needs to be slightly greater than the height of the ground buffer structure of this utility model (10 cm), which greatly reduces the required depth of the pit 31 and the amount of gravel 50 required, and relatively significantly reduces the construction cost of the gravel area 30.

[0038] See also Figure 5 As shown, when constructing the gravel area 30, in addition to laying a layer of non-woven fabric 41 in the pit 31, placing the ground buffer structure of this utility model on it, and pouring in gravel 50, another layer of non-woven fabric 42 can be laid on the surface of the gravel layer, and artificial turf 60 or rubber board (EPDM) can be set on the upper non-woven fabric 42 to form another implementation state.

[0039] See Figure 7 As shown, the ground buffer structure provided in the second embodiment of this utility model differs from that in the first embodiment in that:

[0040] In addition to being circular, the force-bearing ring 21 of the buffer cylinder 20 can also be rectangular. At the same time, the through hole 211 of the force-bearing ring 21 and the through hole 12 of the frame 10 can also be rectangular, thus forming another implementation state.

[0041] See Figure 8As shown, the ground buffer structure provided in the third embodiment of this utility model differs from that in the first embodiment in that:

[0042] The frame 10 has a hexagonal frame portion 11, and also has a recessed portion 14 and a protruding portion 15, which can be assembled into the required shape as needed.
