Method for manufacturing elastic cushion body and elastic cushion body

The present invention relates to a method for manufacturing a cushion body and a cushion body, and in particular to a method for manufacturing an elastic cushion body and an elastic cushion body.

Elastic mats, such as yoga mats, exercise mats, etc., are commonly used in homes or gyms for users to exercise on them, so as to reduce the reaction force caused by the ground and reduce the discomfort and burden of users.

The conventional elastic cushion body can be made of foam and has a uniform thickness. However, the foamed cushion body has a smooth surface and low friction. When the user changes actions on it, it is easy to slip and fall. In order to solve this problem, some manufacturers additionally glue a pattern layer on the elastic cushion body to increase the friction of the elastic cushion body.

However, the elastic cushion body is elastic and deforms after being used and stretched. Therefore, after long-term use, the texture layer will begin to crack or separate, which may cause damage to the elastic cushion body.

In view of this, how to improve the structural configuration of the elastic cushion body to solve the above-mentioned problems has become the goal of the relevant industry.

As a result, the thinner part of the made elastic cushion body has lower elasticity and rough surface, which can increase the stability of the user's exercise on it. In addition, the thicker part retains better elasticity and friction Due to the feature of low force, the user can select the area to be stepped on or supported according to the action, thereby increasing the versatility of the elastic cushion body.

According to an embodiment of the aforementioned elastic cushion body manufacturing method, in the molding step, the foamed material is cold-pressed or hot-pressed.

According to an embodiment of the aforementioned elastic cushion body manufacturing method, in the molding step, the foamed material can be crushed so that an actual length of the finished elastic cushion body conforms to a predetermined length.

According to another embodiment of the present invention, a method for manufacturing an elastic cushion body is provided, which consists of a foaming step, a molding step, and a cutting step. In the foaming step, a raw material is foamed to form a Foam material; in the molding step, the foam material is molded so that the thickness of at least part of the foam material is smaller than the thickness of the other part to form an elastic cushion; and in the cutting step, the elastic cushion is cut Body so that an actual length of the elastic cushion body meets a preset length.

According to an embodiment of the aforementioned elastic cushion body manufacturing method, in the molding step, the foamed material is cold-pressed or hot-pressed.

Please refer to FIGS. 1 and 2. FIG. 1 shows a block flow diagram of a method 100 for manufacturing an elastic cushion body according to an embodiment of the present invention, and FIG. 2 shows the method 100 for manufacturing an elastic cushion body in FIG. 1 Schematic diagram of the steps. The method 100 for manufacturing an elastic cushion body is composed of a foaming step 110 and a molding step 120. In the foaming step 110, a raw material is foamed to form a foaming material 310; and in the molding step 120 , The plastic foaming material 310 makes the thickness of at least a part of the foaming material 310 smaller than the thickness of the other part to form an elastic cushion body 300.

As a result, the thinner part of the elastic cushion body 300 made has lower elasticity and rough surface, which can increase the stability of the user. In addition, the thicker part retains the more elastic and less frictional parts. Therefore, the user can select the area to be stepped on or supported according to the action, thereby increasing the versatility of the elastic cushion body 300. The details of the method 100 for manufacturing the elastic cushion body will be described in detail later.

In detail, the raw material can be, but not limited to, thermoplastic polyester (TPE), ethylene-vinyl acetate copolymer (EVA), thermoplastic polyurethane (TPU), thermoplastic polyolefin (TPO, such as polyethylene, polyvinyl chloride, etc.), etc. , The raw material is chemically extruded and foamed in the foaming step 110 to be molded into a long plate shape, and then in the molding step 120, a pressing head is used to press on at least a part of the foaming material 310 in a hot or cold pressing manner Molding is performed to reduce the thickness of at least a part of the foam material 310, and the reduction in thickness will reduce the elasticity and the surface will become wrinkled and rough, and then a hard layer region 320 can be formed, and the part that is not hot or cold pressed is For the soft layer area 330. In other words, as shown in Figure 2, in the elastic cushion body 300, the thickness H1 of the hard layer region 320 is smaller than the thickness H2 of the soft layer region 330, and the hard layer region 320 is roughened due to shrinkage, and the friction force is relatively large. It can have the function of allowing the user to move stably, and the soft layer area 330 has the characteristics of good elasticity and low friction, so that the user can choose the area to be stepped on or supported according to the action.

Further, the foaming material 310 can be pressed at intervals through the pressure head, so that the hard layer area 320 and the soft layer area 330 are arranged in a staggered manner, and each hard layer area 320 has a first length D1, and each soft layer area 330 It has a second length D2, and the first length D1 is equal to the second length D2. In other embodiments, the first length and the second length can be configured according to requirements, and are not limited to the above disclosure.

In addition, in the shaping step 120, the foamed material 310 can be crushed to make an actual length of the finished elastic cushion body 300 meet a predetermined length. Since the foam material 310 is extruded into a long plate shape, its actual length may be longer than the preset length. Therefore, the foam material 310 can be directly crushed by hot pressing or cold pressing, so that the actual length can be equal to the preset length. That is, there is no need to cut the foamed material 310 by additional machinery or labor, and the cutting step can be omitted. In addition, the method 100 for manufacturing the elastic cushion body does not need to be laminated to the texture layer, and it also has the advantages of simplifying the manufacturing process and reducing the cost.

Please refer to FIG. 3, where FIG. 3 is a perspective view of an elastic cushion body 300 made by the elastic cushion body manufacturing method 100 of FIG. The layer regions 330 are arranged staggered along an arrangement direction, and the arrangement direction is parallel to the longitudinal direction L1.

Please refer to FIGS. 4 and 5. FIG. 4 shows a block flow diagram of a method 200 for manufacturing an elastic cushion body according to another embodiment of the present invention, and FIG. 5 is a method for manufacturing an elastic cushion body using FIG. 4 A three-dimensional schematic diagram of an elastic cushion body 400 made of 200. The method 200 for manufacturing an elastic cushion body consists of a foaming step 210, a molding step 220, and a cutting step 230. The foaming step 210 and the molding step 220 are similar to the foaming step 110 and the molding step 120 in Figure 1 However, the foam material is not crushed in the shaping step 220, but the elastic cushion body 400 is cut in the cutting step 230 so that an actual length of the elastic cushion body 400 meets a predetermined length.

In the elastic cushion body 400, the arrangement direction of the hard layer area 420 and the soft layer area 430 is perpendicular to the longitudinal direction L1. Therefore, it is not suitable to directly crush the foamed material by cold pressing or hot pressing. Therefore, it can be further cut in the cutting step 230, The elastic cushion body 400 is cut mechanically or manually so that the actual length of the elastic cushion body 400 is equal to the preset length.

In other embodiments, the hard layer area may also be surrounded by the soft layer area, and is not limited to the above disclosure.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone familiar with the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection of the present invention The scope shall be subject to the definition of the attached patent application scope.
