As shown in FIG. 1, the bumper mat assembly 100 for infant and toddler education according to the present invention includes at least a pair of combination plates, and basically includes an upper mat unit 10 as a plate mat, (50).

The upper mat unit 10 and the bottom mat unit 50 are used as mats that can be spread in a mutually plane manner and when they are spread in a plane with the same length in the connected plane, .

As in the various embodiments described below, the upper mat unit 10 constitutes the upper body or receiving portion of the structure as a game hall, and the bottom mat unit 50 is used as a bottom body or an insert of the structure.

The upper mat unit 10 and the bottom mat unit 50 are made of a variety of synthetic resin materials such as synthetic rubber, synthetic rubber, rigid high-density sponge, and relatively rigid foamed resin material, Thereby preventing injury.

2A, the plate material constituting the upper mat unit 10 and the bottom mat unit 50 may be a plate material in which the connecting band portion H is thermally bonded between the units to expose them so as to form a fold line,

As shown in Fig. 2B, which is an enlarged view of E in Fig. 1, synthetic water support such as vinyl paper or the like which encapsulates the elastic sheet P in its inside is used for prevention of injury of infants, increase of aesthetic appearance, It is preferable to make the outer shell K of the elastic plate P and finish it with a zipper (not shown) or the like to accommodate the elastic plate P and replace the inner elastic plate P if necessary.

The fold line F, which is the fold line of the upper mat unit 10 and the bottom mat unit 50, can be joined and bonded to the outer casing C constituting the other side flap.

Therefore, the plate-like structure adopted in the upper mat unit 10 and the bottom mat unit 50 of the present invention is not particularly limited,

(1) Exposed ordinary elastic material such as synthetic rubber, rigid high-density sponge, and relatively rigid foamed resin material are exposed and joined on one side of the folded line F by thermal compression or the like .

(2) As shown in part A of Fig. 1, for the purpose of preventing frictional injuries of infants and young children, increasing aesthetic appearance, cleaning water, etc., a synthetic resin paper such as vinyl paper in the form of wrapping an elastic plate material P therein, The upper plate 10 and the bottom plate 10 are integrally formed with each other so that the elastic plate P can be received and replaced if necessary with the zipper The connecting wire F which is the folding line of the mat unit 50 may be any of those formed by connecting with the outer casing C of the other side member.

It is preferable that the elastic plate member P or the cover member C that constitutes the upper mat unit 10 and the bottom mat unit 50 or the cover member C to be exposed is divided into various primary colors in order to induce curiosity of infants and young children Do.

Although the upper mat unit 10 and the bottom mat unit 50 are described as being one in the following description of the constitution, it is needless to say that two or more flaps can be constituted when elastic buffering is further demanded.

The upper mat unit 10 and the bottom mat unit 50, which are based on such an elastic plate, are configured to be folded in order to form various kinds of play or play bodies to be described later, As shown in the figure, the bottom mat unit 50 has a length corresponding to the purpose described below and extends leftward (rightward) with respect to the center bottom main plate 51 of the rectangular member, 52 and the first-second flap 53 on both sides with the connecting wire F at the center as a reference.

The connecting wire F may be constituted by a string or a thermocompression bonding, a stiffening connecting line of the casing C or the like so as to be connected to one side of the thickness t of the mat along this line as described above.

The first main flap 51 and the first 1-1 flap 52, the first 1-1 flap 52 and the first 1-2 flap 53 are provided so as not to give an unnecessary elastic force at the time of formation of the structure to be described later The connecting wires F are provided on mutually opposite surfaces so that a right angle is formed when the connecting wires F are folded to form a desired structure.

The widths c1 and c2 of the first-first flap 52 and the first-second flap 53 connected to the bottom main plate 51 are set so as to absorb the thickness t of the mat, It is preferable to form one flap 52 longer than the inner first flap 53 by the thickness t of the mat. This is because the two flaps, which are exemplarily foldable, The second-1 flap 55 and the second-2 flap 56 are also connected to the right (left) side of the bottom mat unit 50.

The widths c3 and c4 of the second-1 flap 55 and the second 2 flap 56 are set to be equal to the widths c1 and c2 of the first 1-1 flap 52 and the first 1-2 flap 53, Preferably larger than the widths c1 and c2 of the first 1-1 flap 52 and the 1-2 flap 53 by about 6t. However, it is not always necessary to set such a standard, And can be variably set within the range of technical thought in the range.

The width c4 of the second-2 flap 56 is formed to be longer than the width c3 of the second-1 flap 55 by about 4t.
