Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a mosaic suspended interlocking floor. Background Technology

[0002] With the acceleration of urbanization and the improvement of people's living standards, the demand for outdoor activity spaces is growing. Suspended interlocking flooring, due to its performance advantages, has become the preferred material for outdoor sports venues, school playgrounds, and other similar spaces. At the same time, people's pursuit of quality of life and their love for outdoor sports and leisure activities are also driving the continued increase in market demand. Suspended interlocking flooring mainly consists of a baseboard and patterned panels. The patterned panels are made of elastic materials, such as rubber, and are characterized by anti-slip, wear-resistant, and comfortable properties. The patterned panels are arranged in rectangular rows on the upper surface of the baseboard and are detachably connected to it. The existing parquet panels combine a "soft layer" and a "hard layer." The soft layer addresses the issues of "safety and experience" (cushioning, anti-slip, and comfort), avoiding the "hard damage" and "discomfort" of hard materials. The hard layer addresses the issues of "support and stability" (load-bearing capacity, deformation resistance, and durability), avoiding the "easy collapse" and "dimensional instability" of soft materials. The combination of the two forms a "soft on the outside and rigid on the inside" structure, which not only meets the usage needs of different scenarios (sports, children, and leisure), but also takes into account the long-term durability and assembly stability of the floor. This is one of the core design features of the "functional adaptability" of the parquet suspended interlocking floor. However, the Poisson's ratios of the "soft layer" and the "hard layer" differ. The soft layer expands laterally significantly, while the hard layer, due to its high rigidity and limited lateral expansion, exerts a "constraining tensile force" on the soft layer. Without buffer space, the soft layer will be "stretched and deformed" by the hard layer, resulting in localized bulges and wrinkles. Conversely, if the hard layer contracts due to temperature changes while the soft layer contracts less laterally, the "interlayer shrinkage difference" will cause the soft layer to warp, ultimately resulting in an uneven surface. Based on this, this utility model proposes a parquet suspended interlocking floor. Utility Model Content

[0003] The purpose of this invention is to provide a mosaic floating interlocking floor that solves the problem of uneven surface.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model discloses a parquet suspended interlocking floor, including a joist support at the bottom, a surface layer snapped onto the top of the joist support, the surface layer including an integrally formed hard surface layer and a soft surface layer, the soft surface layer being located at the upper end of the hard surface layer; the soft surface layer has a break groove, the bottom of the hard surface layer and the joist support are connected together by a number of snap-fit ​​mechanisms and positioning mechanisms; the hard surface layer has a number of break holes.

[0005] Furthermore, the breaking grooves are distributed in a grid pattern.

[0006] Furthermore, the snap-fit ​​mechanism includes a plurality of positioning slot mechanisms located at the bottom of the main body layer of the keel support, and the bottom of the main body of the rigid surface layer is provided with a snap-fit ​​mechanism that cooperates with the positioning slot mechanisms.

[0007] Furthermore, the positioning slot mechanism includes a plurality of downwardly extending positioning slots formed on the main body layer, with symmetrically arranged locking legs in the positioning slots, the top of the locking legs integrally formed with a limiting shoulder, and a first locking head integrally formed on the slot wall of the positioning slot to cooperate with the limiting shoulder. The buckling mechanism includes a buckle disposed on the lower end face of the surface layer body, and the bottom of the buckle is integrally formed with a second buckle head that cooperates with the limiting shoulder.

[0008] Furthermore, the positioning slot has an opening at the top and an anti-slip base at the bottom.

[0009] Furthermore, the positioning mechanism includes a plurality of enclosing holes formed on the upper end face of the upper main body layer, and an enclosing shaft that cooperates with the enclosing holes is formed on the lower end face of the surface layer main body.

[0010] Furthermore, the hard surface layer and the soft surface layer are integrally formed by a two-color injection molding process.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows: This utility model of interlocking suspended interlocking flooring divides the soft surface layer into multiple relatively independent small pieces by creating interrupted grooves. When subjected to external forces, the smaller size of each piece results in a more uniform stress distribution, reducing stress concentration caused by differences in Poisson's ratio. Simultaneously, the interrupted grooves act as stress release channels. When stress arises between the soft and hard surface layers, it can be released to some extent through the grooves, effectively preventing unevenness caused by stress concentration. Several interrupted holes on the hard surface layer divide it into multiple independent "small units." Stress is blocked by these holes. When the hard surface layer shrinks due to cooling, the holes effectively block and release stress, preventing it from pulling in a single direction and avoiding the surface edge warping. During high-temperature expansion, the holes can also accommodate some of the expansion, reducing arching caused by the surface layer being squeezed inwards. Attached Figure Description

[0014] like Figure 1-4 As shown, a parquet suspended interlocking floor includes a joist support 1 at the bottom, with a surface layer snapped onto the top of the joist support 1. The surface layer includes an integrally formed rigid surface layer 2 and a flexible surface layer 3, with the flexible surface layer 3 located above the rigid surface layer 2. The flexible surface layer 3 has a break groove 301. The bottom of the rigid surface layer 2 and the joist support 1 are connected by several snap-fit ​​and positioning mechanisms. The break groove 301 is distributed in a grid pattern, dividing the flexible surface layer 2 into multiple relatively independent small blocks. This means the lateral expansion force of the entire flexible surface layer is divided into "local expansion forces of individual small units," with each unit's expansion amount being only 1 / 16 to 1 / 25 of the original entire surface. The stress is dispersed within the break groove 301, preventing overall tension.

[0015] The rigid surface layer 2 has several interrupted holes. A continuous rigid surface layer 2 allows stress to be evenly transmitted along the surface, eventually concentrating at the edges or joints. The interrupted holes divide the surface layer into multiple independent "small units," where stress is blocked and dispersed within these small units, preventing large-scale stress concentration and reducing warping / arching forces at the source. When internal stress reaches a certain level, it will preferentially be released at the holes—for example, when the surface layer shrinks due to cooling, the holes effectively block and release stress, preventing it from being stretched in a single direction and avoiding the stress pulling the surface layer edges upwards. During high-temperature expansion, the hole space can also accommodate some of the expansion, reducing arching caused by the surface layer being squeezed inwards.

[0016] The snap-fit ​​mechanism includes several positioning slots located at the bottom of the main body layer 101 of the keel support 1, and a snap-fit ​​mechanism that cooperates with the positioning slots is provided at the bottom of the main body 201 of the rigid surface layer 2. The snap-fit ​​mechanism snaps into the slot mechanism, which improves the connection strength compared to the traditional interference fit and makes it less likely for the surface layer to be pulled out.

[0017] The positioning slot mechanism includes several downwardly extending positioning slots 102 formed on the main body layer 101. The top of each positioning slot 102 is open, and an anti-slip base 107 is installed at the bottom. The positioning slots 102 can be used as support points to avoid the sudden increase in local pressure on the keel support 1 due to concentrated loads on a full-plane surface (such as the impact of a single foot pushing off the ground or a heavy object pressing on a small area), which could lead to problems such as rib breakage or denting of the keel support 1. Multi-point support can more evenly distribute the force on the keel support 1 itself, preventing deformation such as sagging in the middle or warping at the edges due to long-term load-bearing, and maintaining the overall structural rigidity.

[0018] The positioning slot 102 is symmetrically equipped with clamping legs 103. The top of each clamping leg 103 has an integrally formed limiting shoulder 106. The groove wall 104 of the positioning slot 102 has an integrally formed first clamping head 105 that mates with the limiting shoulder 106. The latching mechanism includes a latch 202 installed on the lower end face of the surface layer body 201. The bottom of the latch 202 has an integrally formed second clamping head 203 that mates with the limiting shoulder 106. The latch 202 is pressed downwards into the groove formed in the middle of the clamping leg 103. The first clamping head 105 and the second clamping head 203 cooperate with each other to interlock with the limiting shoulder 106 on the clamping leg 103, achieving mutual locking between the keel support 1 and the surface layer, preventing the latch 202 from disengaging, and improving connection strength.

[0019] The positioning mechanism includes several enclosing holes 108 formed on the upper surface of the upper main body layer 101, and an enclosing shaft 204 that mates with the enclosing holes 108 is formed on the lower surface of the surface layer main body 201. The enclosing holes 108 and the enclosing shaft 204 are interference-fitted. This positioning mechanism effectively ensures the fit between the surface layer and the joists, creating a tight connection between the rigid surface layer 2 and the joist support 1, reducing gaps and looseness between the surface layer and the joists. This tight connection ensures that when the surface layer is subjected to external forces, such as foot traffic or impacts, the force can be effectively transferred to the joists, preventing warping, deformation, or loosening of the surface layer, thus ensuring the flatness and stability of the floor.

[0020] The upper surface of the upper main body layer 101 has several slots 108, and the lower surface of the surface layer 201 has several locking blocks 204 that cooperate with the slots 108. These serve to position and engage the components, ensuring the stability and uniformity of the connection and preventing unevenness.

[0021] The rigid surface layer 2 and the flexible surface layer 3 are integrally molded using a two-color injection molding process, eliminating the need for a rigid adhesive. During the curing process, the molecular structure of the rigid adhesive changes, transforming from a liquid or viscous state to a solid state. This reduces the distance between molecules, generating shrinkage stress. This shrinkage stress accumulates throughout the rigid adhesive layer, increasing the risk of warping and buckling, which in turn leads to surface layer warping or buckling. Producing the rigid surface layer 2 and the flexible surface layer 3 using a two-color injection molding process reduces surface layer damage caused by rigid adhesive shrinkage, extending the lifespan of the flooring.
