For example, each second foam part 16 is made of natural rubber NR. Foamed 10-20 times, the first foamed part 14 is foamed 1-2 times using natural rubber NR).

In this way, each second foam member 16 has a lower hardness than the first foam member 14 and is also lighter in weight than the first foam member 14 (under the same volume, an elastic material with a high expansion ratio is lighter). Therefore, , if the composition of the first foam part 14 and each second foam part 16 is regarded as an elastic layer, the weight of the cushion body 10 of the present invention can be higher than that of a cushion body that completely uses hard foam parts to form the elastic layer. Light.

Secondly, the pad 10 of the present invention can be used as a protective pad for carpets. As shown in the second figure, the pad 10 is directly placed on the carpet 1 with the hooking parts 12 facing downwards. In this way, each of the hooking parts 12 The hook line 24 can hook the pile 2 on the surface of the carpet 1, so that the pad body 10 is fixed on the surface of the carpet 1, which can prevent the carpet 1 from being stained or the carpet from being accidentally damaged during construction or transportation.

In addition, since there are a plurality of hook lines 24 on the bottom side of the mat body 10, it can also be used as a scrubbing tool. For example, the mat body 10 can be stepped on and each hook line 24 can be used to scrub the dirty floor at home.

As shown in the third figure, it is the cushion body 40 of the second preferred embodiment of the present invention. Its structure is generally the same as the aforementioned cushion body 10. The same components use the same symbols. The difference is that the hooking part 12 is It is attached to the top side of the first and second foam parts 14 and 16, and each hook line 24 protrudes upward.

As shown in the fourth figure, it is the cushion body 50 of the third preferred embodiment of the present invention. Its structure is generally the same as the aforementioned cushion body 10. The difference is that its hooking member 52 does not have the aforementioned first recess. 26, a plurality of openings 56 are provided through the base plate 54, and each second recess 30 of the first foam member 14 protrudes to the bottom side of the base plate 54 through each opening 56, and the hooking member 52 Each hook line 58 protrudes from the bottom end of each second recess 30 .

In addition, as shown in the fifth and sixth figures, they are the cushion bodies 60 and 70 of the fourth and fifth preferred embodiments of the present invention. The compositions of the two are generally the same as the aforementioned cushion bodies 10 and 50. The differences are The cushion bodies 60 and 70 further include one surface material 62 and 72 respectively. Each surface material 62 and 72 is respectively attached to the top side of the first foam part 14 and can be a rubber sheet or a plastic sheet (NR, NR, 72). PU, TPE, EVA or PVC, etc.), wood chips, bamboo chips, woven sheets or carpet sheets with a velvety surface.

In particular, the above-mentioned mat bodies 10, 40, 50, 60, 70 can be respectively used for yoga mats or floor coverings (such as conventional wooden floors, etc.):

As shown in the seventh figure, when each of the mat bodies 10, 40, 50, 60, and 70 is used for a yoga mat 80, the yoga mat 80 includes a bottom pad 82, and the bottom pad 82 includes a floor-mounted pad. The piece 84 has an anti-slip effect and can be made of foam materials such as NR, TPE, SBR or EVA for laying on the ground. The top side of the floor piece 84 is combined with a plurality of loops 86, which are made of nylon wire, etc. Made of woven material, it can be used for one or more of the pad bodies 10, 40, 50, 60, 70 (wherein, the surface materials 62, 72 of the pad bodies 60, 70 can be made of the same or different rubber sheets or plastic sheets or The hook lines 24 and 58 of the woven sheet are hooked together, so that the mat body 10, 40, 50, 60, 70 can be fixed on the top side of the bottom mat 82 to become the yoga mat 80. Therefore, when the yoga mat 80 is worn over time, the mat bodies 10, 40, 50, 60, and 70 can be directly replaced (when using one mat body 10, 40, 50, 60, and 70). By replacing the bottom pad 82, the worn parts of the pads 10, 40, 50, 60, and 70 can also be replaced individually (when multiple pads 10, 40, 50, 60, and 70 are used), thereby achieving economical and environmentally friendly effects, and The yoga mat 80 can also use a plurality of mat bodies 60 and 70 with different surface materials 62 and 72 materials, so that the yoga mat 80 can produce different anti-slip effects in different parts and is very flexible in use. For example, it can be used for yoga exercises. The user selects and adjusts each pad body 10, 40, 50, 60, 70 of the yoga mat 80 in advance according to different yoga postures to obtain better and safer yoga exercise effects.

When the mats 60 and 70 are used as floor paving parts, their structure is basically the same as the yoga mat 80. The difference is that the bottom mat 82 is adhered to the ground, and the surface materials 62 and 72 of the mats 60 and 70 are It can be one of rubber sheets or plastic sheets (NR, PU, TPE, EVA or PVC, etc.), wood chips, bamboo chips, woven sheets or carpet sheets with velvet surfaces. When the surface materials 62 and 72 of the cushion body 60 and 70 are used When wood chips are used, the floor covering becomes a wooden floor. When the surface materials 62 and 72 of the mats 60 and 70 are carpet sheets with piles on the surface, the floor covering becomes a carpet. Moreover, when you want to replace the floor paving parts or change part of the floor paving parts, you only need to replace the pad bodies 60 and 70 using surface materials 62 and 72 of different materials, or change part of the pad bodies 60 and 70. The replacement operation is very convenient.

As can be seen from the above, as shown in the eighth figure, the present invention further provides a method 100 for manufacturing the cushion body 10. The first step is to prepare the hooking member 110 and the foam material 110: prepare the hooking member 12, a hard hair Foam material and a soft foam material. Each first recess 26 is preformed on the hooking member 12. The hard foam material is foamed to form the first foam member 14 and is selected from natural rubber. Elastic foaming materials such as NR, nitrile rubber (NBR), styrene-butadiene rubber (SBR), polyurethane PU, TPU, TPE, EVA or PVC are added with foaming agents, accelerators and other foaming auxiliaries. A conventional tablet extruder presses the tablet into a plate shape and then extrudes to form each of the second recesses 30. The soft foam material is foamed to form the second foam parts 16, and is made of natural rubber NR or the like. Foam material is generally in the shape of a ball. An appropriate amount of a compound that can react with water to produce gas is added to the material. This compound is isocyanate (ISOCYANATE), etc. When water is added, a chemical reaction can occur to produce carbon dioxide. The amount of this compound and water used It can be flexibly adjusted, mainly because the foaming ratio of the soft foam material is greater than that of the hard foam material during subsequent heating and foaming. Changing the amount of water can control the amount of carbon dioxide produced, and obtain soft foam materials with different foaming degrees.

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

The third step of the manufacturing method 100 is a water foaming treatment 130: disassemble the soft foam material into a plurality of pieces and stuff them into each second recess 30 of the hard foam material, and add water to each second recess. The soft foam material within 30 years old causes chemical reactions of the compounds in the soft foam material to produce a large number of bubbles and form a group-shaped soft foam material with a large number of bubbles, which is called water foaming or water foaming (not water foaming). Heated foam molding).

The final step of the manufacturing method 100 is heating forming 140: the attached hooking piece 12, the hard foam material and the soft foam material are input into an oven for heating, so that the hard and soft foam materials can be foamed and connected with the hook. The parts 12 are bonded together (the foaming ratio of the soft foam material is about 10-20 times, which is higher than 1-2 times of the hard foam material), and the pad body 10 can be obtained after cooling.

In addition, as shown in Figure 9, the present invention also provides a manufacturing method 200 of the cushion body 60. The steps are generally the same as the manufacturing method 100. The difference is that the water foaming step 130 and the heating forming step 140 are different. It includes a step of attaching the surface material 210: the surface material 62 is attached to the surface of each of the hard and soft foam materials to prepare the cushion body 60 with the surface material 62.

Furthermore, by changing the hooking part 12 in the step of preparing the hooking part and the foam material 110 in the manufacturing method 100 of the present invention to the hooking part 52, the pad body 50 can be made. The pad body 70 can be made by changing the hooking part 12 in the step of preparing the hooking part and the foam material 110 in the manufacturing method 200 of the present invention to the hooking part 52.

In summary, the present invention provides a mat body, a manufacturing method thereof, a yoga mat using the mat body, and a floor paving member, which are made possible through the cooperation of the hooking members, the first foaming members, and the second foaming members. , can reduce the weight of the pad body and can be fixed on the carpet surface to prevent construction workers from stepping on the carpet and contaminating the carpet or accidentally carrying items. If the carpet is damaged carefully, it can also be used as a floor scrubbing tool by stepping on it. In addition, it can also be used as a component of yoga mats and floor paving parts, which has great practical value. The reason is that the present invention does meet the requirements for an invention patent and is in accordance with the law. Make an application.
