A grass protection mat and a mat assembly having the same are provided. The grass protection mat of the invention includes a body made of polygonal portions, pillars protruded upward from the body, buffer wings protruded upward from the body between the pillars for distributing weights, an outer frame at the periphery of the body, lug members protruded from lower parts of the body and the outer frame. The mat also includes slide-type hooking means laterally protruded for connection of the mats, an opening formed at the inner surface of the outer frame. The mat assembly includes various forms of mat fastening members for connecting the grass protection mats. The invention facilitates connection of the mats and enhances assemblability of the mat assembly, effectively preventing sinking of the mats into the ground, thereby maintaining protection of grass.

1. A grass protection mat system comprising: at least one mat, each mat comprising: a body made of polygonal portions connected to each other, forming spaces for growing grass;pillars integrally protruded upward from the body;an outer frame connecting with the periphery of the body to maintain the shape of the mat;lug members integrally protruded from lower parts of the body and the outer frame;hooking means laterally protruded at the outer frame, for enabling connection of the mat, andan opening formed at the inner surface of the outer frame, for receiving hooking means of an another adjacent mat,wherein the opening of the mat includes a fastening hole formed through an extension plate integrally and laterally formed on a point of the outer frame and disposed inside of the outer frame, in a corresponding position of the hooking means of the another adjacent mat,wherein an opening of an adjacent mat includes a fastening hole formed through an extension plate integrally and laterally formed on a point of an outer frame of the adjacent mat, in a corresponding position of the hooking means of the mat,wherein the hooking means of the mat is of a slide-type mechanism including: bodies laterally protruded from a plurality of regions of the outer frame of the mat and extended downward, each having a cutout perpendicularly formed through a corresponding one of the bodies for resilient operation, andhooks integrally protruded outwardly from both sides of lower parts of the bodies,wherein some of the hooks of the mat are fixedly inserted through, and extend below, the fastening hole of the adjacent mat, and wherein upper surfaces of the some of the hooks are supported by, and in contact with, an underside of the extension plate of the adjacent mat, andwherein the opening of the mat further includes a guiding groove that is formed on the fastening hole of the opening of the mat and enables slide insertion of the hooking means of the another adjacent mat securely into the fastening hole of the opening of the mat, the guiding groove further enables the hook of the hooking means to be moved along to be fastened into the opening. 2. The grass protection mat system according to claim 1, wherein the polygonal portions comprise one selected from a group consisting of rectangle, hexagon and octagon. 3. The grass protection mat system according to claim 1, each mat further comprising buffer wings integrally protruded upward from the body in the space between the pillars. 4. The grass protection mat system according to claim 1, each mat further comprising a sinking prevention means provided in a lower part of the mat to prevent the mat from sinking into the ground. 5. The grass protection mat system according to claim 1, wherein the guiding groove enables the hook of the hooking means to be moved along in a constricted state to be fastened into the opening. 6. The grass protection mat system according to claim 4, wherein the sinking prevention means comprise rounded plates each perpendicularly and integrally formed at a lower part of a corresponding one of reinforcement plates integrally formed between the lug members, to increase sinking prevention effects of the mat by ground contacts of the rounded plates. 7. A grass protection mat comprising: a body made of polygonal portions connected to each other, forming spaces for growing grass;pillars integrally protruded upward from the body;lug members integrally protruded from lower parts of the body and the outer frame; andsinking prevention means provided in a lower part of the mat to prevent the mat from sinking into the ground,wherein the sinking prevention means comprise rounded plates each perpendicularly and integrally formed at a lower part of a corresponding one of reinforcement plates integrally formed with and between two adjacent ones of the lug members, to increase the sinking prevention effects of the mat by ground contacts of the rounded plates,wherein the sinking prevention means further comprise reinforcement ribs, each of the reinforcement ribs integrally formed between a corresponding one of the reinforcement plates and a corresponding one of the rounded plates, the reinforcement ribs disposed perpendicular to the reinforcement plate and the rounded plate,wherein each of the reinforcement plates extends vertically from a lower end part of the lug members to, and is in direct contact with a bottom side of the body, andwherein each of the rounded plates is large enough in size so that each of the rounded plates is in direct contact with two adjacent lug members. 8. The grass protection mat according to claim 7, further comprising: buffer wings integrally protruded upward from the body in the space between the pillars; andan outer frame connecting with the periphery of the body to maintain the shape of the mat. 9. The grass protection mat according to claim 8, further comprising: hooking means laterally protruded at the outer frame, for enabling connection of the mat; andan opening formed at the inner surface of the outer frame, for receiving hooking means of an another adjacent mat. 10. The grass protection mat according to claim 9, wherein the hooking means are of a slide-type mechanism including: bodies laterally protruded from a plurality of regions of the outer frame and extended downward, each having a cutout perpendicularly formed through a corresponding one of the bodies for resilient operation; andhooks integrally protruded outwardly from both sides of lower parts of the bodies to be fixedly inserted into fastening holes of corresponding openings of an adjacent mat. 11. The grass protection mat according to claim 9, wherein the opening includes: a fastening hole formed through an extension plate integrally and laterally formed on a point of the outer frame, in a corresponding position of the hooking means of the another adjacent mat; anda guiding groove that is formed on the fastening hole and enables slide insertion of the hooking means of the another adjacent mat into the fastening hole of the opening. 12. The grass protection mat according to claim 7, wherein the polygonal portions comprise one selected from a group consisting of rectangle, hexagon and octagon. 13. The grass protection mat according to claim 7, wherein round plate that is integrally formed on the each of the reinforcement plates is disposed between the two adjacent lug members. 14. The grass protection mat according to claim 7, wherein each of the reinforcement plates is integrally formed with only one corresponding one of the rounded plates. 15. The grass protection mat according to claim 7, wherein each pair of the lug members is integrally formed with only one corresponding one of the rounded plates.
