Abstract

The present invention relates to a prefabricated mat block having both shock absorption and load distribution functions. The mat is composed of a plurality of shell structure cushioning cells (110) in the upper layer, a middle layer cushioning bridge (210) connecting them, and a lower layer support column (310) that transmits the load to the ground. The load is first absorbed through the cushioning cells and then distributed to the support column via the cushioning bridge, which reduces load concentration and provides a comfortable user experience. In particular, fastening grooves (410) and fastening protrusions (420) are arranged alternately on the outer side to enable easy fastening between blocks, and some support columns are omitted and fastening grooves or fastening protrusions are placed in those positions to simultaneously ensure connectivity and elasticity. In addition, half cushioning bridges (210a), quarter cushioning bridges (210b), half support columns (310a), and quarter support columns (310b) are configured to effectively distribute the load even on the outer edge. This structure allows for safe and hygienic use in various environments, such as bathrooms, kitchens, and outdoors, and is very easy to clean due to its simple assembly and disassembly.

Description

Modular Mat Block for Shock Absorption, Load Distribution, and Interfloor Noise Reduction The present invention relates to a floor mat, and more specifically, to a prefabricated mat block having a load distribution structure and shock absorption function, which is installed on the floor surface of an indoor space to effectively distribute the weight of a user or external load to prevent structural damage caused by load concentration, and simultaneously mitigate the impact and noise generated during walking to reduce inter-floor noise. In particular, the present invention belongs to a technical field in which production and construction are easy and stable support and shock absorption performance can be provided in various environments by modularizing a plurality of cell structures, bridges connecting them, and a bottom support structure. In modern residential and commercial spaces, impacts and loads generated by walking, exercise, and furniture movement are directly transmitted to the floor, frequently leading to structural damage or inter-floor noise issues. Particularly in multi-unit dwellings such as apartment buildings, floor impact noise is transmitted directly to the floor below, becoming a major cause of conflict among residents; consequently, the demand for flooring materials or mats to address this issue is continuously increasing. Traditionally, general cushion mats and soundproofing mats made of elastic materials have been used, but they present the following problems. Mats composed of a single flat structure or simple foam materials struggle to distribute loads evenly and easily deform or degrade in performance when loads are concentrated in specific areas. As the material compresses with repeated use, elasticity decreases and the shape deforms, resulting in a failure to maintain long-term shock absorption performance. Furthermore, due to a lack of structural shock blocking or air-layer-based acoustic insulation designs, they often fail to effectively block noise transmission in practice. Conventional one-piece mats frequently require cutting or custom fabrication to fit the installation space, presenting limitations in terms of ease of installation and flexible applicability. To solve these problems, there is a demand for a load-distributing prefabricated mat configured in a three-layer structure of multiple buffer cells, bridges connecting them, and support columns that distribute the load to the ground, which can be modularized for assembly. The present invention is based on the technical background for responding to this demand. FIG. 1 shows the shape of each component.

The present invention relates to a prefabricated mat block (1000) designed to effectively absorb and disperse external shocks or loads, and in particular to a multi-layered mat designed to provide cushioning, reduce fatigue, and improve durability by gradually transmitting the user's weight through each component when the user's weight is applied to the mat. Looking at the shape and connection structure of a multi-layered prefabricated mat block, which is the core component of the present invention and consists of an upper layer (cushioning cell), a middle layer (cushioning bridge), and a lower layer (support column), the upper layer is a structure composed of a plurality of cushioning cells (110) (hereinafter referred to as 'cell'), and each cushioning cell (110) basically has a three-dimensional body shape. In the present invention, these cushioning cells are not solid structures filled with substance, but are implemented as shell shapes with an open bottom and a certain thickness on the remaining surface. As a result, the inside of the cell remains hollow, and a structure that is lightweight and highly elastic is formed overall. The shell shape not only enhances the ease of the molding process but also simultaneously achieves overall product weight reduction and material savings. When subjected to external impact, the thin, flexible outer structure of the shell undergoes elastic deformation in response to the load, followed by a return to its original shape. This process provides the user with excellent cushioning and elastic recovery, helping to maintain a comfortable and stable user experience, particularly in environments where the foot is used barefoot. Additionally, the cell sidewall (111) of each buffer cell (110) may be designed to have a shape that is narrower at the top and gradually widens towards the bottom, or to have a structure that slopes inward toward the t
