The hooking member 12 is made of nylon yarn and other materials, and is roughly wavy, including a base plate 22 and a plurality of hook lines 24. The base plate 22 is formed with a plurality of first recesses 26, each of which is hooked. 24 is a wire body with a hook-shaped end, protruding from the base plate 22 and the bottom side of each first recess 26 . Of course, the hooking member 12 can also be molded with plastic and other materials to form the base plate 22 and the plurality of hooking lines 24 .

The first foam member 14 is made by foaming elastic foam materials such as natural rubber NR, and is pasted on the top side of the substrate 22 and each first recess 26. It is roughly wavy and includes a flat plate 28 and A plurality of second indentations 30 , the flat plate 28 corresponds to the substrate 22 , and each of the second indentations 30 corresponds to each of the first indentations 26 .

Each of the second foaming parts 16 is respectively arranged in the interior of each of the second recesses 30 in a complementary shape, and is made of elastic foaming material such as natural rubber NR, and its hardness is lower than that of the first foaming part 14. (The expansion ratio of each of the second foaming parts 16 is higher than that of the first foaming parts 14, and its hardness can be lower than that of the first foaming parts 14. For example, each of the second foaming parts 16 utilizes natural rubber NR 10-20 times of foaming, the first foam member 14 utilizes natural rubber NR to foam 1-2 times).

Thereby, each of the second foaming parts 16 is lighter than the first foaming part 14 except that the hardness is lower than that of the first foaming part 14 (under the same volume, the elastic material with high expansion ratio is lighter in weight), so If the composition of the first foaming part 14 and each second foaming part 16 is regarded as an elastic layer, the weight of the pad body 10 of the present invention can be relatively fully utilized to form the pad body of the elastic layer by hard foaming parts. lighter.

Secondly, the pad body 10 of the present invention can be used as a protective pad body for the carpet. As shown in FIG. First, each hook line 24 of the hooking member 12 can hook the fluff 2 on the surface of the carpet 1, so that the pad body 10 can be fixed on the surface of the carpet 1, which can prevent the carpet 1 from being stained or accidentally damaged during construction and handling. The carpet not only effectively protects the carpet, but also provides better bearing capacity.

In particular, each of the

aforementioned pads

10, 40, 50, 60, 70 can be used for yoga mats or ground laying parts (such as conventional wooden floors, etc.):

As shown in Figure 7, when each of the

mat bodies

10, 40, 50, 60, 70 is used for a yoga mat 80, the yoga mat 80 includes a bottom pad 82, and the bottom pad 82 includes a ground sheet 84, which has an anti-slip effect, can be made of foaming materials such as NR, TPE, SBR or EVA, and can be laid on the ground. The top side of the ground sheet 84 is combined with a plurality of loops 86, which are made of nylon wire and other materials, for one or more of the

pads

10, 40, 50, 60, 70 (wherein, the

surface materials

62, 72 of the

pads

60, 70 can be made of the same or different rubber sheets or plastic sheets or braided sheet)

hook lines

24,58 hooked, so that the

mat body

10,40,50,60,70 can be fixed on the top side of the bottom pad 82 to become the yoga mat 80. Thereby, when the yoga mat 80 is used for a long time and wears out, the

mat body

mat body

10, 40, 50, 60, 70 of the yoga mat 80 in advance to obtain better and safer yoga movement effects.

And when the

mat body

60,70 is applied to the ground laying parts, its composition is generally the same as the yoga mat 80, the difference is that the bottom pad 82 is stuck on the ground, and the

surface material

62, 72 can be one of sheet materials such as rubber sheet or plastic sheet (NR, PU, TPE, EVA or PVC etc.), wood chip, bamboo chip, weaving sheet or the carpet sheet of surface tool nap. When the

surface materials

62, 72 of the

pad body

60, 70 use wood chips, the ground laying part becomes a wooden floor; Laying pieces become carpets. And, when wanting to change this ground laying part or change part of the ground laying part, only need to change the

cushion body

60, 70 that uses different

material surface material

62, 72, or change part of the

cushion body

60, 70, and the replacement action is very convenient.

The soft foam material is foamed to form the foam material of each second foam member 16, which is natural Foaming materials such as rubber NR are generally in the form of a ball, and an appropriate amount of compound that can react with water to generate gas is added to the material. The compound is isocyanate (ISOCYANATE), etc. When water is added, it can produce a chemical reaction to generate carbon dioxide. The compound and The amount of water used can be adjusted flexibly, mainly because the expansion ratio of the soft foamed material is greater than that of the hard foamed material when the soft foamed material is foamed and molded by subsequent heating. The change of the water consumption can control the amount of carbon dioxide produced and obtain different foaming degrees. soft foam material.

The second step of the manufacturing method 100 is to attach the hooking member and the rigid foam material 120: the hard foam material is pasted in such a way that each of the second recesses 30 corresponds to each of the first recesses 26. on the top side of the hooking piece 12.
