Technology Field

[0001] The present invention relates to a foldable exercise mat, and more specifically, to a foldable exercise mat whose size can be freely adjusted according to the user's convenience. Background Technology

[0002] With the recent rise in interest in health management, the number of people exercising regularly is increasing, and indoor exercise, which is not restricted by the external environment, is enjoying great popularity.

[0003] Mat exercises are effective for strengthening muscles, improving balance, increasing flexibility, and relieving pain, and can be performed without strain even by those who do not usually exercise or have weak muscles. Furthermore, since mat exercises require no special equipment other than a mat to reduce pressure on specific parts of the body during movements, they have the advantage of being able to be performed not only in dedicated exercise spaces like gyms but also in private spaces such as homes.

[0004] Generally, exercise mats consist of a cushioning material made of foamed natural rubber or synthetic rubber (such as nitrile-butadiene rubber or neoprene) and an outer covering material that encases the cushioning material.

[0005] However, conventional exercise mats are formed by foaming rubber, making them heavy and bulky, which makes them difficult to move. Furthermore, conventional exercise mats cannot be perfectly folded, making them inconvenient to use; moreover, if they are forcibly folded, slippage occurs between the contact surfaces, posing a problem that makes it difficult to ensure stability during exercise movements.

[0006] Therefore, there has been a demand for exercise mats that can be folded or unfolded according to user needs and do not cause interlayer slippage when folded. Prior art literature

[0019] The present invention will be described below with reference to the attached drawings. However, the present invention may be implemented in various different forms and is therefore not limited to the embodiments described herein. Furthermore, in order to clearly explain the present invention in the drawings, parts unrelated to the explanation have been omitted, and similar parts throughout the specification have been given similar reference numerals.

[0020] Throughout the specification, when it is stated that a part is "connected (connected, in contact, combined)" with another part, this includes not only cases where they are "directly connected," but also cases where they are "indirectly connected" with other members interposed between them. Furthermore, when it is stated that a part "includes" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but rather allows for the inclusion of additional components.

[0021] The terms used herein are merely for describing specific embodiments and are not intended to limit the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this specification, terms such as “comprising” or “having” are intended to indicate the presence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.

[0022] FIG. 1 is a plan view of an exercise folding mat (1) according to one embodiment of the present invention, and FIG. 2 is a cross-sectional view of an exercise folding mat (1) according to one embodiment of the present invention.

[0023] An exercise folding mat (1) may include a lower material (10) having a non-slip function against the floor, a cushioning material (20) having a shock-absorbing function, and an upper material (30) having a non-slip function against the body. At this time, the lower material (10), the cushioning material (20), and the upper material (30) may be stacked and bonded in order.

[0024] The lower member (10) may be formed in the shape of a rectangular sheet. Specifically, the lower member (10) may be formed in the shape of a rectangular sheet that is long in one direction, but is not limited thereto.

[0025] The cushioning material (20) may be composed of a plurality of cushioning pads (21) spaced apart from each other. At this time, the cushioning pads (21) may be formed in the shape of circular or square sheets with a width smaller than that of the lower material (10), and may be arranged in rows, columns, or rows and columns.

[0026] The upper member (30) may be formed in the shape of a rectangular sheet. Specifically, the upper member (30) may be formed in the shape of a rectangular sheet that is long in one direction, but is not limited thereto. The upper member (30) may be formed in the same shape as the lower member (10) to correspond to it.

[0027] The lower member (10) and the upper member (30) can implement a non-slip function through pores formed inside. The pores of the lower member (10) and the upper member (30) are formed with different sizes, so the degree of non-slip function of the lower member (10) and the degree of non-slip function of the upper member (30) may be different.

[0028] A portion of the lower member (10) and the upper member (30) may be joined to the cushioning material (20), and the remaining portion may be joined to each other. Specifically, a portion of the lower member (10) and the upper member (30) positioned corresponding to the cushioning pad (21) may be joined to the cushioning pad (21) by facing it with the cushioning pad (21) in between, and the remaining portion of the lower member (10) and the upper member (30) not positioned corresponding to the cushioning pad (21) may be joined to each other by facing it directly. Accordingly, the portion of the exercise folding mat (1) where the cushioning pad (21) is located may be formed as a cushion (C) capable of reducing pressure applied to the user's body or absorbing shock, and the portion where the cushioning pad (21) is not located may be formed as a folding line (L) that is easy to fold.

[0029] As a result, the present invention can be fully folded or unfolded according to the user's needs, and since no slip occurs between contact surfaces even when used in the folded state, safe use is possible.

[0030] FIG. 2 is a cross-sectional view of a foldable exercise mat (1) according to one embodiment of the present invention.

[0031] The cushioning material (20) may be formed thicker than the lower material (10) and the upper material (30). Specifically, the cushioning material (20) may be formed with a thickness of 2 to 20 cm, and the lower material (10) and the upper material (30) may be formed with mutually equal thickness.

[0032] In the present invention, a cushioning material (20) in the shape of a narrower top and wider bottom is shown from the upper surface toward the lower surface, but it is not limited thereto and various shapes can be applied as long as they can reduce pressure applied to the user's body or absorb shock.

[0033] FIG. 3 is a diagram showing the usage state of a foldable exercise mat (1) according to one embodiment of the present invention, illustrating a state in which it is folded into various shapes.

[0034] FIG. 3(a) shows an exercise folding mat (1) folded in half with respect to the center, and FIG. 3(b) shows an exercise folding mat (1) folded twice with both sides overlapping the center.

[0035] In addition to the form shown in Fig. 3, the exercise folding mat (1) can be folded in a vertical direction or folded in a portion multiple times to enhance the cushioning of a specific area.

[0036] In other words, the present invention can be folded into various shapes based on the folding line (L), allowing it to be transformed into a shape suitable for exercise movements or usage spaces.

[0037] FIG. 4 is a plan view of a foldable exercise mat (1') according to another embodiment of the present invention.

[0038] The exercise folding mat (1') according to another embodiment of the present invention differs from the exercise folding mat (1) according to the aforementioned embodiment only in the number and size of the cushioning pads (21), and the other configuration is the same as the first embodiment.

[0039] The cushioning pads (21) can be arranged in an NxM (N, M are natural numbers) array, and their shape and size are not particularly limited. That is, the appearance of the exercise folding mat (1) equipped with cushioning pads (21) arranged in a 3x6 array as shown in FIG. 1 and the exercise folding mat (1') equipped with cushioning pads arranged in a 2x2 array as shown in FIG. 4 are merely examples and can be implemented in various modified ways.

[0040] Meanwhile, the number of cushions (C) and folding lines (L) can be determined according to the number and arrangement of cushioning pads (21).

[0041] FIG. 5 is a scanning electron microscope (SEM) image of a lower non-slip layer (11) according to one embodiment of the present invention, and FIG. 6 is a scanning electron microscope (SEM) image of an upper non-slip layer (31) according to one embodiment of the present invention.

[0042] Below, the lower member (10) and the upper member (30) will be described in detail with reference to FIG. 2.

[0043] The lower member (10) may include a lower non-slip layer (11) formed of a fiber-based wet polyurethane sheet and a lower reinforcing layer (12) formed of a thermoplastic polyurethane sheet on the upper surface of the lower non-slip layer (11).

[0044] The lower non-slip layer (11) can be formed by removing the substrate from a fiber-based wet polyurethane sheet attached to the lower reinforcing layer (12). More specifically, the lower non-slip layer (11) can be formed by removing the substrate after a fiber-based wet polyurethane sheet, formed by solidifying a polyurethane solution applied to a fiber substrate and then immersed in a coagulation liquid, is heat-transferred and pressed with the lower reinforcing layer (12). At this time, the fiber-based wet polyurethane sheet may have a plurality of first pores formed inside through a substitution reaction between dimethylformamide (DMF) of the polyurethane solution and water of the coagulation liquid during the solidification process.

[0045] The lower reinforcing layer (12) can be formed by laminating a thermoplastic polyurethane sheet to a fiber-based wet polyurethane sheet.

[0046] After the lower non-slip layer (11) and the lower reinforcing layer (12) are heat-transfer compressed, the substrate of the fiber-based wet polyurethane sheet can be removed, and subsequently, the lower reinforcing layer (12) can be bonded to the cushioning material (20) and the upper material (30).

[0047] The lower material (10) formed by the above process can maintain the elasticity of the fiber-based wet polyurethane sheet and improve durability, thereby effectively suppressing the problem of tearing or damage during the use of the mat.

[0048] The upper member (30) may include an upper non-slip layer (31) formed of a film-based wet polyurethane sheet and an upper reinforcing layer (32) formed of a thermoplastic polyurethane sheet on the lower surface of the upper non-slip layer (31).

[0049] The upper non-slip layer (31) can be formed by removing the substrate from a film-based wet polyurethane sheet attached to the upper reinforcing layer (32). More specifically, the upper non-slip layer (31) can be formed by removing the substrate after a film-based wet polyurethane sheet, formed by solidifying a polyurethane solution applied to a film substrate and then immersed in a coagulation liquid, is heat-transferred and pressed with the upper reinforcing layer (32). At this time, the film-based wet polyurethane sheet may have a plurality of second pores formed inside through a substitution reaction between dimethylformamide (DMF) of the polyurethane solution and water of the coagulation liquid during the solidification process.

[0050] The upper non-slip layer (31) can be formed to be at least 1.25 times thicker than the lower non-slip layer (11). Accordingly, it is resistant to scratches and does not wear out even with frequent friction with the body, and can absorb physical impact.

[0051] The upper reinforcing layer (32) can be formed by laminating a thermoplastic polyurethane sheet to a fiber-based wet polyurethane sheet.

[0052] After the upper non-slip layer (31) and the upper reinforcing layer (32) are heat-transfer compressed, the substrate of the fiber-based wet polyurethane sheet can be removed, and subsequently, the upper reinforcing layer (32) can be bonded to the cushioning material (20) and the lower material (10).

[0053] The upper material (30) formed by the above process can maintain the elasticity of the film-based wet polyurethane sheet and improve durability, thereby effectively suppressing the problem of tearing or damage during the use of the mat.

[0054] Meanwhile, the first pore may be formed with a larger size than the second pore, and may be fewer in number than the second pore. This is due to differences in the substrate of the wet polyurethane sheet.

[0055] When a first pore is formed by a substitution reaction during the coagulation process of a fiber-based wet polyurethane sheet, dimethylformamide and water pass through the fiber substrate, and compared to a film-based wet polyurethane sheet, the pore size is formed larger and the number of pores can be formed smaller. At this time, the size of the first pore may be 20 to 100 μm.

[0056] On the other hand, when second pores are formed by a substitution reaction during the solidification process of a film-based wet polyurethane sheet, dimethylformamide and water do not pass through the PET film and are substituted as they are, and compared to a fiber-based wet polyurethane sheet, the pore size is formed smaller and the number of pores can be formed in large numbers. At this time, the size of the second pores may be 200 to 900 nm.

[0057] Accordingly, the lower non-slip layer (11) may have good contact characteristics with the floor due to large pores, and the upper non-slip layer (31) may not only have good contact characteristics with the body due to a large number of pores, but also allow for sublimation transfer, enabling various design expressions.

[0058] FIG. 7 is a flowchart illustrating the manufacturing process of a foldable exercise mat (1) according to one embodiment of the present invention.

[0059] An exercise folding mat (1) can be manufactured through a lower material forming step (S10), an upper material forming step (S20), a lower material temporary bonding step (S30), an upper material temporary bonding step (S40), and a final bonding step (S50).

[0060] The lower material formation step (S10) is a step of forming a lower material (10) composed of a lower non-slip layer (11) and a lower reinforcing layer (12) that are mutually laminated and bonded. As the substrate is removed after heat transfer lamination of a fiber-based wet polyurethane sheet and a thermoplastic polyurethane sheet, the lower non-slip layer (11) and the lower reinforcing layer (12) that are mutually laminated and bonded can be formed.

[0061] The upper material formation step (S20) is a step of forming an upper material (30) composed of an upper non-slip layer (31) and an upper reinforcing layer (32) that are mutually laminated and bonded. As the substrate is removed after heat transfer lamination of a film-based wet polyurethane sheet and a thermoplastic polyurethane sheet, the upper non-slip layer (31) and the upper reinforcing layer (32) that are mutually laminated and bonded can be formed.

[0062] The order of the lower material formation step (S10) and the upper material formation step (S20) may be reversed.

[0063] The lower member temporary bonding step (S30) is a step of temporarily bonding the lower member (10) and the cushioning pad (21). The cushioning pad (21) can be temporarily bonded to the upper surface of the lower member (10) placed on the work table in a row, column, or row and column. At this time, the lower member (10) and the cushioning pad (21) can be temporarily bonded by a first bonding means (B1, see FIG. 2), and the first bonding means (B1) can be any one of double-sided tape, adhesive, and bond.

[0064] The upper member temporary bonding step (S40) is a step of temporarily bonding the upper member (30) and the cushioning pad (21). The upper member (30) can be placed over the lower member (10) that has been temporarily bonded to the cushioning pad (21) and can be temporarily bonded to the cushioning pad (21). At this time, the upper member (30) and the cushioning pad (21) can be temporarily bonded by a second bonding means (B2, see FIG. 2), and the second bonding means (B2) can be any one of double-sided tape, adhesive, and bond.

[0065] The final joining step (S50) is a step of joining the lower member (10), the cushioning material (20), and the upper member (30) as a single unit. The lower member (10) and the upper member (30) can be heat-compressed at least once using a heat-pressing press. Accordingly, the lower member (10) and the upper member (30) are joined with the cushioning material (20) in between, so that a cushion (C) can be formed in the part where the cushioning pad (21) is located, and a folding line (L) can be formed in the part where the cushioning pad (21) is not located.

[0066] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will understand that other specific forms can be easily modified without altering the technical spirit or essential features of the present invention. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. For example, each component described as a single unit may be implemented in a distributed manner, and components described as distributed may likewise be implemented in a combined form.
