Description

Puzzle type mat and puzzle type mat assembly {PUZZLE TYPE MAT AND PUZZLE TYPE MAT ASSEMBLY}

The present invention relates to a mat, and more particularly, to a puzzle-type mat and a puzzle-type mat assembly in which several mats are simply assembled in a horizontal direction to complete a single solid mat.

In general, mats used in homes or gyms are mostly laid out in the form of a single thick flat plate to prevent floor noise or injuries to infants, infants, and children.

Accordingly, a puzzle-type mat that combines and uses several mats in a puzzle-type to cope with various types of floors has emerged. Accordingly, the puzzle-type mat is provided with a groove or protrusion for coupling to one of the puzzle-type mats as in Prior Art Document 1, and is fitted into a complementary groove and protrusion among the other puzzle-type mats to complete the mat assembly. The type of mat is predominantly.

In more detail, in the prior art document 1, in addition to grooves or protrusions for coupling, stepped grooves and stepped protrusions in the vertical direction are provided. However, in the case of using grooves and protrusions formed in the horizontal direction when combining, it is easy to move the mats in the horizontal direction and combine them with each other, but the mats of this structure are separately provided with step grooves and step protrusions in the vertical direction, so that the mating is not possible. There is a problem that is not easy.

In other words, when the step protrusion is bound to the step groove formed in the vertical direction, the coupling force will increase, but it becomes difficult to bind by smoothly sliding each mat in the horizontal direction. Since the separation force in the vertical direction must be applied together with the separation force, it is very difficult to maintain and repair after installation, such as the occurrence of cracks in the center direction of the mat.

Furthermore, prior art document 2 discloses a mat in which grooves and protrusions for coupling are provided in a vertical direction. Therefore, it is inherently impossible to move and combine each mat only in the horizontal direction. Accordingly, there is a need for a puzzle-type mat or a puzzle-type mat assembly that is combined only by moving in the horizontal direction to ensure a solid coupling force while being easily combined.

Hereinafter, a puzzle-type mat and a puzzle-type mat assembly according to an embodiment of the present invention will be described. 1 is a top perspective view of a puzzle-type mat according to an embodiment of the present invention, FIG. 2 is a bottom perspective view of a puzzle-type mat according to an embodiment of the present invention, and FIG. 3 is an enlarged view of area A in FIG. 4 is an enlarged view of area B in FIG. 2, FIG. 5 is an enlarged view of area C in FIG. 2, and FIGS. 6 and 7 show a state in which puzzle-type mats according to an embodiment of the present invention are coupled to each other. It is a bottom perspective view showing.

Referring to the drawings, the puzzle-type mat 1000 according to an embodiment of the present invention comprises an upper surface 10 having a substantially rectangular shape, a lower surface 20 corresponding to the upper surface, and a side surface 30. In the side surface 30, the insertion protrusions 110 and 120 and the upper groove 200 are formed on the lower side. In this case, the insertion protrusions 110 and 120 are fitted into the insertion groove 200 formed in another puzzle-type mat to be fastened to each other.

The upper surface 10 has a quadrangular shape, in which case it has 4 vertices and 4 sides. However, in the puzzle-type mat 1000 according to the present embodiment, two or more insertion protrusions 110 and 120 are formed on one side 30 of the puzzle-type mat, and the insertion protrusion formed at a position relatively far from the vertex 1 The shape of the (first insertion protrusion, 110) and the insertion protrusion (second insertion protrusion, 120) formed at a relatively close position from the vertex (1) are formed differently.

That is, the puzzle-type mat 1000 according to the present embodiment has another adjacent first insertion protrusion 110 and the second insertion protrusion 120 protruding outward from the upper surface at a set thickness in order to maximize the fastening force. It is fastened in the horizontal direction to the insertion groove 200 of the puzzle-type mat, but when the shape of the first insertion protrusion 110 and the second insertion protrusion 120 are the same, it is only possible to combine them in one row or one row as a whole. It is not possible to combine both columns and rows in plural.

In other words, in order for the unit puzzle-type mat 1000 of the puzzle-type mat assembly to form a plurality of columns and rows in a uniform shape, a portion having a vertex where all four puzzle-type mats 1000 meet must not have a protruding part. Therefore, in the second insertion protrusion 120 disposed close to the portion with the vertex, the shape of the vertex side (area B and 4 in FIG. 2) is formed differently from the shape of the opposite side, and the vertex corresponding to the quadrangular shape of the upper surface It is also formed on the lower surface 20 as it is.

In more detail, referring to FIG. 3, the first insertion protrusion 110 includes a first protrusion 130a and a second protrusion 130b. As shown in FIG. 4, the second insertion protrusion 120 is one It is formed to consist of only the first protrusion 130a, and both the first protrusion 130a and the second protrusion 130b are formed on the other side. That is, the shapes of the first insertion protrusion 110 and the second insertion protrusion 120 are formed identically to the outside with respect to the upper surface 10, but are not formed to the inside of the upper surface 10.

Further, it can be seen that from a portion consisting of only the first protrusion 130a on one side to the vertex 1 is formed of a rectangular vertex and a corner corresponding to a quadrangle of the upper surface when referring to region B in FIG. 2. Therefore, another adjacent puzzle-type mat can be combined with each other without interference.

The insertion groove 200 is formed in the inner direction of the upper surface 10 on at least one of the side surfaces 30 of the puzzle-type mat 1000, and for coupling with another puzzle-type mat, the number of insertion protrusions is the same. It is preferably formed. In addition, it is preferable that the depth of the insertion groove 200 is depressed to be the same as the length of the insertion protrusions 110 and 120 protruding outward with respect to the upper surface.

However, referring to FIGS. 2, 3, and 5, it can be seen that the insertion groove 200 is formed by connecting from the side surfaces of the insertion protrusions 110 and 120. That is, in the insertion groove 200, a groove having a shape complementary to the shape of the portion where the insertion protrusions 110 and 120 protrude from the upper surface 10 is formed, so that the protruding portions of the insertion protrusions 110 and 120 are horizontally Will be inserted.

By the way, the first insertion protrusion 110 and the second insertion protrusion 120 are both made including a first protrusion 130a, and the first insertion protrusion 110 further includes a second protrusion 130b. Done. In more detail, the second insertion protrusion 120 includes a first protrusion 130a and a second protrusion 130b on one side, and the other side includes only the first protrusion 130a.

3 to 5, the first protrusion 130a is a first rounding part 131 that first contacts when different puzzle mats are combined, and a first horizontal extending from the first rounding part 131. The portion 133 and a first inclined portion 135 connected to the first horizontal portion 133 and forming an acute angle with the first horizontal portion 133 are included.

The first rounding part 131 is a part that first comes into contact when different puzzle mats are combined. Therefore, it is preferable that it is rounded in order to reduce the friction of entering with another puzzle-type mat. Further, the first horizontal portion 133 is formed by connecting in a direction opposite to the horizontal direction in which the first rounding portion 131 extends in order to perform a role in which the first rounding portion 131 protrudes horizontally.

The first inclined portion 135 is formed to be connected from the horizontal portion, and forms an acute angle with the first horizontal portion 133 in order to facilitate horizontal sliding coupling while adding friction when detaching from another puzzle-type mat.

At this time, the second protrusion 130b is formed in a shape extending from the first protrusion, and both are formed in a shape of origin symmetric with each other. The origin at this time is a point where the first inclined portion 135 and the second inclined portion 135' meet. The second protrusion 130b has a second inclined portion 135' extending in a straight line from the first inclined portion 135, and the first inclined portion 135 and the second inclined portion 135' are extended to the outer surface ( A second horizontal portion 133' that is returned by the length protruding in the X direction of FIG. 5) and a second rounding portion 131' that allows the first rounding portion 131 to be accommodated.

However, referring to FIG. 5 in this case, the height h1 of the first rounding portion or the height h2 of the second rounding portion is formed to be smaller than the sum h3 of the height of the first vertical portion and the height of the second vertical portion. . 6 and 7, when the mat is fastened, the first protrusion 130a enters first, and then the second protrusion 130b enters the insertion groove 200, the height of the first rounding portion (h1). Alternatively, when the height of the second rounding portion (h2) is equal to or greater than the sum of the heights of the first vertical portion and the second vertical portion (h3), the force applied when the puzzle-type mats are fastened to each other in the horizontal direction is remarkable. Increases.

That is, as the acute angle formed on the inclined portions 135 and 135 ′ increases, smooth sliding fastening becomes possible, so the height h1 of the first rounding portion 131 or the height h2 of the second rounding portion 131 ′ is the first It is preferable that it is formed to be smaller than the sum (h3) of the height of the vertical portion and the height of the second vertical portion. At this time, for smoother sliding during fastening, an inclined surface 210 is formed inside the portion corresponding to the upper surface 10 in the insertion groove 200.
