Description

Technology Field

[0001] The present invention relates to a foam roller capable of adjusting the elasticity of its surface according to the amount of air injected. Background Technology

[0003] Modern people's posture is deteriorating due to excessive smartphone use and prolonged computer work. As a result, an increasing number of enthusiasts are preferring exercises such as Pilates and yoga to correct their posture.

[0004] In particular, Pilates utilizes various tools for exercise, and types of equipment used include foam rollers, gym balls, stretching bands, and circle rings.

[0005] Among these, the foam roller, widely used for stretching, is a rod-shaped device used in rehabilitation and posture correction. It relieves pain through self-myofascial release therapy—that is, full-body stretching and self-massage—and reduces the burden on the spine and muscles by developing core muscles through core exercises.

[0006] Generally, EVA foam rollers are suitable for beginners due to their light and soft sponge material, while EPP foam rollers are suitable for advanced users due to their heavy firmness and hard material. Additionally, textured foam rollers are used to massage specific areas such as the calves, thighs, and back.

[0007] As such, since foam rollers with different materials, elasticity levels, and surface shapes are used depending on the grade or the area of ​​application, purchasing costs for using various types of foam rollers increase. Furthermore, due to the nature of foam rollers—which are long cylindrical in shape and have a large external volume—there are problems such as the need for significant storage space to store multiple foam rollers.

[0008] Furthermore, using a foam roller that does not suit the user's physical condition can actually strain specific body parts, leading to problems such as purchasing a foam roller, leaving it unused, and then buying another one to use.

[0009] As prior art, Published Patent Application No. 10-2023-0029028 discloses a portable foam roller.

[0010] The aforementioned patent uses a cylindrical tube as a body and injects air to use it as a foam roller; however, it is formed in an air-like shape for portable use and cannot be used with a hard surface. Although an outer shell with protrusions can be attached to and detached from the tube, it has the disadvantage of being a simple attachment type and the inability to arbitrarily adjust the elasticity of the protrusions.

[0011] In addition, since the above patent does not have a heating function, it could not provide a hot compress effect. Prior art literature

[0013] Published Patent Application No. 10-2023-0029028 (Portable Air Foam Roller, March 3, 2023) The problem to be solved

[0015] In addition, the present invention provides a foam roller capable of adjusting surface elasticity, which can provide a hot compress effect by being equipped with a heating element and providing a warming function.

[0016] In addition, the present invention provides a foam roller capable of adjusting surface elasticity, which can form air protrusions at intervals set according to the amount of air injected, as well as pressure protrusions. means of solving the problem

[0029] Hereinafter, a foam roller capable of adjusting surface elasticity according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0030] As described above, the foam roller with adjustable surface elasticity according to the present invention is a foam roller that allows a user to arbitrarily adjust the elasticity of the surface, and comprises a cylindrical support body (10) and an air pad (20) provided to surround the circumference of the support body (10).

[0031] The support body (10) is formed hard with a flat surface and is molded with a resin material, etc.

[0032] The support body (10) is formed in a cylindrical shape having a predetermined diameter and length according to the specifications of a standard foam roller.

[0033] The air pad (20) is provided on the periphery, that is, the outer surface, of the support body (10), and a receiving space is formed to accommodate air inside.

[0034] An air inlet (21) is formed on one side of the air pad (20) for injecting air into the internal space.

[0035] The air inlet (21) can be formed in a bidirectional structure, that is, in the form of a bidirectional nozzle that allows both the injection and discharge of air to be freely carried out, and a cap may be provided to block the discharge after the air is injected.

[0036] Additionally, the air inlet (21) can be configured as a unidirectional structure with a barrier formed inside, that is, when air is injected, the barrier opens due to the air injection pressure and air is injected, and when air is not injected and there is no injection pressure, the barrier that was open closes and the discharge of the injected air is blocked.

[0037] At this time, memory foam may be provided inside the air pad (20) for cushioning, and if memory foam is provided, an air passage through which air can pass between the memory foams must be formed.

[0038] The present invention allows the surface elasticity of the air pad to be controlled by adjusting the amount of air injected into the air pad (20).

[0039] For example, when the air injection amount of the air pad (20) is 0%, there is no air in the internal space of the air pad, so it adheres flatly to the support (10), and thus the foam roller is used with the hard surface strength of the support (10).

[0040] And when the air injection amount of the air pad (20) is 100%, it is filled with air and has elasticity in a taut, inflated state. When the air injection amount of the air pad is 70%, the elasticity is reduced compared to when it is 100%, so it has a slightly more cushioned elastic action. When it is 50%, which is lower than 70%, the elasticity is further reduced, so it has a soft, cushioned state.

[0041] Therefore, users can adjust the elasticity to suit them according to the amount of air injected, and since elasticity can be controlled by adjusting the injection amount, it has the advantage that both beginners and experts can use it at a strength suitable for them.

[0042] Here, air protrusions may be formed on the surface of the air pad (20) at set intervals.

[0043] The air protrusions (not shown) can be effective when more than 90% of air is injected into the air pad (20), and a pressure point effect can be provided by the air protrusions.

[0044] Meanwhile, the foam roller of the present invention can be configured to provide a hot compress function.

[0045] Specifically, the support body (10) is formed as a hollow body having a space inside, and a heating means (30) is installed on the outer surface of the support body (10) so as to be positioned between it and an air pad (20).

[0046] The heating means (30) may be configured as a heating wire or a planar heating element that is turned ON by a power supply and generates heat. In this case, it may be configured as a heating wire, but it is preferable to configure it as a planar heating element rather than a heating wire to address volume issues and ensure uniform heat transfer.

[0047] In the case where the heating means is configured as a planar heating element, the planar heating element can be wrapped around the circumference of the support body (10), so it can be configured thinly, and heat can be transferred to the entire surface of the air pad, thereby increasing the hot compress effect.

[0048] For the ON / OFF operation of the heating means, a power button (40) is provided on one side of the support body (10), and a control unit (45) is installed on one side inside the support body (10) to be circuit-connected to the power button (40).

[0049] A battery is installed in the control unit (45) to supply power to the operating power of the control unit as well as to the heating means (30).

[0050] The battery can be a rechargeable battery or a replacement battery. In the case of a rechargeable configuration, a charging port (not shown) for charging is provided on one side of the support body (10) and is circuit-connected to the control unit (45).

[0051] Meanwhile, since the support body constituting the foam roller of the present invention has a disadvantage of not providing a pressure point effect when used because its outer surface is formed flat, it may be configured to provide a pressure point effect.

[0052] In the first embodiment, pressure protrusions (11) may be formed at set intervals on the perimeter surface of the support body (10), and the air pad (20) is provided on the outer surface of the support body with a hole formed therein so that the pressure protrusions are exposed to the outside in the portion where the pressure protrusions (11) are formed.

[0053] Therefore, when all the air injected into the air pad (20) is discharged, the pressure point (11) protrudes outward, allowing the pressure point (11) to be used and providing a pressure point effect through the pressure point.

[0054] In addition, the amount of air injected into the air pad (20) can be adjusted so that the protrusion height of the acupressure protrusion (11) and the surface height of the air pad (20) are the same, making the entire surface exposed to the outside flat. When the entire surface is made flat, it does not produce a separate acupressure effect, so it can be used when acupressure is not needed.

[0055] Additionally, the air pad (20) can be used by injecting air into it as much as possible so that the surface of the air pad protrudes between the acupressure protrusions (11). In this case, an acupressure effect can be provided by the protruding surface of the air pad, and as the protruding part has elasticity due to the characteristics of the air pad, an acupressure effect is provided as an elastic protrusion rather than a hard protrusion.

[0056] As another embodiment providing a pressure point effect, the support body (10) may be formed as a hollow body with a space inside, and a pressure point foam roller (50) formed with a rough surface having a plurality of protrusions formed inside the hollow interior of the support body (10) may be configured to be inserted.

[0057] If the outer diameter of the acupressure foam roller (50) is formed to be slightly smaller than the inner diameter of the hollow support, it can be effectively stored because it does not easily come out while inserted into the internal space of the support, but the acupressure foam roller may come out during use, storage, or transportation.

[0058] To solve this, a locking pin (55) of the above-mentioned pressure foam roller (50) may be provided.

[0059] The locking pin (55) can be configured to form a rail groove (12) on one side of the support body (10) and to allow the user to manually move it in the rail groove (12).

[0060] When using, the locking pin (55) is moved backward in the rail groove (12) to secure space so that the acupressure foam roller (50) can be inserted into the hollow internal space of the support body (10), and then the acupressure foam roller (50) is inserted into the internal space of the support body (10). After inserting the acupressure foam roller (50) into the internal space of the support body (10), the locking pin (55) that was moved backward is moved forward so that it is supported on one side of the acupressure foam roller (50), and thus the withdrawal operation of the acupressure foam roller is blocked by the one side of the acupressure foam roller being supported by the locking pin.

[0061] A handle groove (52) is formed on one side of the acupressure foam roller (50) to allow the acupressure foam roller (50) to be easily pulled out from the support body (10).

[0062] Drawing reference numeral 15 is a partition wall, configured to partition the control unit and the pressure foam roller from each other within the internal space of the support body, and the partition wall may be formed to partition one side of the internal space of the support body entirely or to partition only the edge by protruding a predetermined length.

[0063] According to the present invention configured as described above, the surface elasticity of the foam roller can be adjusted so that it can be used with an elasticity suitable for the user or with different elasticities for each stretching area, thereby making it more convenient to use compared to conventional foam rollers that are monotonous and formed with only one strength, and reducing costs by eliminating the need to purchase multiple foam rollers with different surface strengths.

[0064] In addition, if a heating means is provided, it becomes possible to receive a hot compress along with stretching due to the heating function.

[0065] In addition, if equipped with an acupressure foam roller, both flat and uneven surfaces can be used, allowing for alternating use depending on the area being stretched. Furthermore, since two users can use it simultaneously, it offers excellent convenience. Explanation of the symbols
