Description

rail structure of a massage device

[0001] The present invention relates to a rail structure of a massage device, and more specifically, to a rail structure of a massage device capable of smoothly moving a ceramic module on a rail by combining a first rail and a second rail through a first tapered portion provided on a first rail and a second tapered portion provided on a second rail.

[0002] Massage devices are designed to alleviate acute or chronic pain occurring in the muscle and nerve tissues of the spine, and various types of spinal thermal massage devices are being developed recently.

[0003] The massage device can apply pressure to body parts to improve blood circulation or relieve sudden muscle stiffness. Additionally, heat generated by the massage device can apply thermal stimulation to the painful area, thereby improving blood flow to the painful area and alleviating pain.

[0004] The massage device may include a ceramic module equipped with a ceramic element that applies pressure to the user, and a rail on which the ceramic module can move. The ceramic module of the massage device moves along the rail and applies pressure to various points on the body.

[0005] However, such a massage device may have the following problems. The rail provided in the massage device may serve as a path for the ceramic module to move, and the rail may be extended in the longitudinal direction. Additionally, the rail may be curved to allow the ceramic module to move along the curves of the body.

[0006] The rail of the massage device can be manufactured as a single part. However, since the rail of the massage device can be extended in the longitudinal direction and curves can be formed in the rail, it may also be manufactured by combining two rails for ease of manufacturing.

[0007] When manufacturing a rail by combining two rails, if the two rails are simply joined, a gap or ledge may be formed at the point where the two rails are joined. If a gap or ledge is formed at the point where the two rails are joined, vibration may occur in the ceramic module due to the gap or ledge when the ceramic module moves along the rail. Vibrations generated in the ceramic module may be transmitted to the user, and such vibrations may cause discomfort to the user.

[0008] The present invention is intended to solve the aforementioned problems, and more specifically, it relates to a rail structure of a massage device that allows a ceramic module to move smoothly on a rail by combining a first rail and a second rail through a first tapered portion provided on a first rail and a second tapered portion provided on a second rail.

[0016] According to one embodiment, the first-2 rail and the second-2 rail of the rail structure of the massage device are provided with gears, and the ceramic module includes a wheel and a module gear with teeth formed on the outer side, and when the ceramic module moves along the first rail and the second rail, the wheel moves along the first-1 rail and the second-1 rail, and the module gear can move along the gear of the first-2 rail and the gear of the second-2 rail.

[0017] The angle formed at the point where the extension line in the longitudinal direction in which the first rail of the rail structure of the massage device according to one embodiment extends meets the extension line in the diagonal direction in which the first tapered portion extends may be 5 to 20 degrees.

[0018] The angle formed at the point where the extension line in the longitudinal direction in which the first rail of the rail structure of the massage device according to one embodiment extends meets the extension line in the diagonal direction in which the first tapered portion extends may be 5 to 55 degrees.

[0042] The present invention relates to a rail structure of a massage device, and more specifically, to a rail structure of a massage device capable of smoothly moving a ceramic module on a rail by combining a first rail and a second rail through a first tapered portion provided on a first rail and a second tapered portion provided on a second rail. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0043] Referring to FIGS. 1 and 2, a massage device according to an embodiment of the present invention includes a rail structure (100) and a ceramic module (200).

[0044] Referring to FIG. 1, the rail structure (100) is provided in a massage device. A massage device according to an embodiment of the present invention may be provided with a frame (10), and the rail structure (100) extending in the longitudinal direction may be provided on the frame (10).

[0045] Referring to FIG. 2, the ceramic module (200) is equipped with a ceramic (210) that presses against a user, and the ceramic module (200) can move along the rail structure (100). According to an embodiment of the present invention, the ceramic module (200) presses against the user's body while moving along the rail structure (100).

[0046] Referring to FIG. 3, the rail structure (100) according to an embodiment of the present invention includes a first rail (110), a first tapered section (120), a second rail (130), and a second tapered section (140).

[0047] Referring to FIGS. 4 and 5, the first rail (110) extends in the longitudinal direction. The first rail (110) may be a rail on which the ceramic module (200) moves, and the ceramic module (200) moves along the first rail (110) that extends in the longitudinal direction.

[0048] The first tapered portion (120) is formed at one end of the first rail (110), and the first tapered portion (120) can be extended diagonally with respect to the length direction while narrowing in width. Specifically, the first tapered portion (120) can be extended diagonally with respect to the direction in which the first rail (110) extends while narrowing in width on the upper surface.

[0049] According to an embodiment of the present invention, the first tapered portion (120) is provided at one end of the first rail (110), and the first tapered portion (120) can be manufactured integrally with the first rail (110).

[0050] The upper surface of the first rail (110) and the first tapered portion (120) according to an embodiment of the present invention may be a surface that contacts the ceramic module (200) at the first rail (110) and the first tapered portion (120).

[0051] Referring to FIGS. 4 and 5, the second rail (130) is extended in the longitudinal direction. The second rail (130) may be a rail on which the ceramic module (200) moves, and the ceramic module (200) moves along the second rail (130) extended in the longitudinal direction.

[0052] The second tapered portion (140) is formed at the other end of the second rail (130), and the second tapered portion (140) can be extended diagonally with respect to the length direction while narrowing in width. Specifically, the second tapered portion (140) can be extended diagonally with respect to the direction in which the second rail (130) extends while narrowing in width on the upper surface.

[0053] According to an embodiment of the present invention, the second tapered portion (140) is provided at the other end of the second rail (130), and the second tapered portion (140) can be manufactured integrally with the second rail (130).

[0054] The upper surface of the second rail (130) and the second tapered portion (140) according to an embodiment of the present invention may be a surface that contacts the ceramic module (200) at the second rail (130) and the second tapered portion (140).

[0055] According to an embodiment of the present invention, the second rail (130) is manufactured separately from the first rail (110), and the second rail (130) can be coupled to the first rail (110). Referring to FIG. 6, according to an embodiment of the present invention, the first rail (110) and the second rail (130) can be coupled through the first tapered portion (120) and the second tapered portion (140).

[0056] Specifically, when the first rail (110) and the second rail (130) are combined, the side of the first tapered section (120) and the side of the second tapered section (140) may be arranged to face each other.

[0057] When the first rail (110) and the second rail (130) are combined while the side of the first tapered section (120) and the side of the second tapered section (140) are arranged to face each other, the ceramic module (200) moves while coming into contact with the upper surfaces of the first tapered section (120) and the second tapered section (140).

[0058] The rail structure (100) according to an embodiment of the present invention can improve the convenience of rail manufacturing by manufacturing the first rail (110) and the second rail (130) separately. If the length of the rail structure (100) becomes too long, it may be difficult to manufacture the rail structure as a single part. In addition, if a curve is formed in the rail structure (100), it may also be difficult to manufacture the rail structure as a single part.

[0059] According to an embodiment of the present invention, the rail structure (100) can be easily manufactured by separating the first rail (110) and the second rail (130), thereby allowing the rail structure (100) to be extended in the longitudinal direction. Additionally, according to an embodiment of the present invention, the rail structure (100) can be easily formed with a curve in the rail structure (100) by separating the first rail (110) and the second rail (130).

[0060] According to an embodiment of the present invention, when the first rail (110) and the second rail (130) are combined, if the first rail (110) and the second rail (130) are simply combined, vibration may occur in the ceramic module (200) at the point where the first rail (110) and the second rail (130) are combined.

[0061] Specifically, when the first rail (110) and the second rail (130) are combined, if a connecting surface is formed that extends in a direction perpendicular to the direction in which the ceramic module (200) moves, vibration may be generated in the ceramic module (200) by the connecting surface. The vibration generated in the ceramic module (200) may be transmitted to the user, and such vibration may cause discomfort to the user.

[0062] However, the rail structure (100) according to an embodiment of the present invention can minimize vibration in the ceramic module (200) by arranging the first rail (110) and the second rail (130) so that the side of the first tapered portion (120) formed on the first rail (110) and the side of the second tapered portion (140) formed on the second rail (130) face each other.

[0063] Referring to FIG. 7, by arranging the side of the first tapered section (120) and the side of the second tapered section (140) so as to face each other, the first rail (110) and the second rail (130) are joined so that the joining surface where the first rail (110) and the second rail (130) are joined can be extended diagonally with respect to the direction in which the ceramic module (200) moves.

[0064] As the coupling surface where the first rail (110) and the second rail (130) are joined is extended diagonally with respect to the direction in which the ceramic module (200) moves, the vibration generated when the ceramic module (200) moves the coupling surface can be reduced, thereby allowing the ceramic module (200) to move smoothly.

[0065] Referring to FIGS. 4 and 5, a first coupling projection (121) protruding outwardly is provided on the side of the first tapered portion (120), and a second coupling groove (142) carved inwardly is provided on the side of the second tapered portion (140).

[0066] According to an embodiment of the present invention, when the first tapered portion (120) and the second tapered portion (140) come into contact, the first coupling projection (121) can be inserted into the second coupling groove (142), thereby allowing the first tapered portion (120) and the second tapered portion (140) to be firmly coupled.

[0067] Referring to FIGS. 4 and 5, a first coupling groove (122) that is inwardly recessed is provided on the side of the first tapered portion (120), and a second coupling projection (141) that protrudes outwardly is provided on the side of the second tapered portion (140).

[0068] According to an embodiment of the present invention, when the first tapered portion (120) and the second tapered portion (140) come into contact, the second coupling projection (141) can be inserted into the first coupling groove (122), thereby allowing the first tapered portion (120) and the second tapered portion (140) to be firmly coupled.

[0069] Additionally, according to an embodiment of the present invention, the first coupling projection (121) and the first coupling groove (122) may be simultaneously provided on the side of the first tapered portion (120), and the second coupling projection (141) and the second coupling groove (142) may be simultaneously provided on the side of the second tapered portion (140).

[0070] When the first tapered portion (120) and the second tapered portion (140) come into contact, the first coupling projection (121) is inserted into the second coupling groove (142), and the second coupling projection (141) can be inserted into the first coupling groove (122). Through this, the first tapered portion (120) and the second tapered portion (140) can be firmly coupled.

[0071] Referring to FIGS. 8 and 9, the first rail (110) according to an embodiment of the present invention may include a first-1 rail (111) having a first tapered portion (120) formed at one end, and a first-2 rail (112) provided on the side of the first-1 rail (111) and extended with a constant width.

[0072] The first-1 rail (111) may be a rail having the first tapered portion (120) formed at one end. The first-2 rail (112) may be a rail that is provided on the side of the first-1 rail (111) while forming a constant width and extends in a direction parallel to the first-1 rail (111). According to an embodiment of the present invention, the first-1 rail (111) and the first-2 rail (112) may be formed integrally.

[0073] Additionally, the second rail (130) according to an embodiment of the present invention may include a second-1 rail (131) having a second tapered portion (140) formed at one end, and a second-2 rail (132) provided on the side of the second-1 rail (131) and extended with a constant width.

[0074] The above second-1 rail (131) may be a rail having the second tapered portion (140) formed at one end. The above second-2 rail (132) may be a rail that is provided on the side of the second-1 rail (131) while forming a constant width and extends in a direction parallel to the second-1 rail (131). According to an embodiment of the present invention, the second-1 rail (131) and the second-2 rail (132) may be formed integrally.

[0075] Referring to FIGS. 8 and 9, one end of the first-2 rail (112) may be provided with a coupling projection (151) that protrudes outward, and the other end of the second-2 rail (132) may be provided with a coupling groove (152) that is cut inward.

[0076] In addition to the first-1 rail (111) and second-1 rail (131) in which the first tapered portion (120) and the second tapered portion (140) are formed, the rail structure (100) according to an embodiment of the present invention can connect the first-2 rail (112) and the second-2 rail (132), which are extended with a constant width, through the connecting projection (151) and the connecting groove (152).

[0077] Through this, the rail structure (100) according to the embodiment of the present invention can more firmly connect the first rail (110) and the second rail (130).

[0078] In FIGS. 8 and 9, the coupling projection (151) is provided at one end of the first-second rail (112) and the coupling groove (152) is provided at the other end of the second-second rail (132), but it is not limited thereto.

[0079] According to an embodiment of the present invention, one end of the first-2 rail (112) may be provided with an inwardly recessed coupling groove (152), and the other end of the second-2 rail (132) may be provided with a coupling projection (151) that protrudes outward. The first-2 rail (112) and the second-2 rail (132) may be coupled as the coupling projection (151) is inserted into the coupling groove (152).

[0080] Referring to FIGS. 8 and 9, the first-2 rail (112) and the second-2 rail (132) according to an embodiment of the present invention may be equipped with a gear (153). Additionally, referring to FIG. 2, the ceramic module (200) according to an embodiment of the present invention may include a wheel (220) and a module gear (230) having teeth formed on the outer side.

[0081] The wheel (220) is formed in a circular shape, and the wheel (220) may be made of a roller without teeth formed on the outer side. The module gear (230) has teeth formed on the outer side, and the module gear (230) may be made of a gear.

[0082] According to an embodiment of the present invention, when the ceramic module (200) moves along the first rail (110) and the second rail (130), the wheel (220) moves along the first-1 rail (111) and the second-1 rail (131), and the module gear (230) can move along the gear (153) of the first-2 rail (112) and the gear (153) of the second-2 rail (132).

[0083] Referring to FIG. 7, the wheel (220) that does not have a gear formed on its outer side may be affected by the joining surface of the first rail (110) and the second rail (130). Accordingly, the wheel (220) can move along the first-1 rail (111) and the second-1 rail (131) which are joined through the first tapered section (120) and the second tapered section (140).

[0084] Referring to FIG. 9, the module gear (230) has teeth formed on its outer side, and the module gear (230) can move along the gear (153) of the first-second rail (112) and the gear (153) of the second-second rail (132). Since the module gear (230) moves through the gears, it can be unaffected by the coupling surface of the first rail (110) and the second rail (130).

[0085] Accordingly, the coupling projection (151) is provided at one end of the first-2 rail (112) where the first tapered portion (120) is not formed, and the coupling groove (152) is provided at the other end of the second-2 rail (132) where the second tapered portion (140) is not formed, so that the first rail (110) and the second rail (130) can be firmly coupled.

[0086] Referring to FIG. 10, the angle formed at the point where the extension line in the longitudinal direction in which the first rail (110) according to an embodiment of the present invention extends meets the extension line in the diagonal direction in which the first tapered portion (120) extends may be 5 to 20 degrees.

[0087] If the angle formed at the point where the extension line in the longitudinal direction of the first rail (110) and the extension line in the diagonal direction of the first tapered section (120) meet is too large (greater than 20 degrees), the intersection angle of the joint surface formed by the first tapered section (120) and the second tapered section (140) in the direction of movement of the ceramic module (200) increases, and vibration may occur in the ceramic module (200).

[0088] Accordingly, it is preferable that the angle formed at the point where the extension line in the longitudinal direction in which the first rail (110) extends and the extension line in the diagonal direction in which the first tapered portion (120) extends meet is less than 20 degrees.

[0089] The smaller the angle formed at the point where the extension line in the longitudinal direction of the first rail (110) and the extension line in the diagonal direction of the first tapered section (120) meet, the smoother the ceramic module (200) can move.

[0090] However, if the angle formed at the point where the extension line in the longitudinal direction of the first rail (110) and the extension line in the diagonal direction of the first tapered section (120) meet is too small (less than 5 degrees), there is a risk of damage occurring at the end of the first tapered section (120) as the strength at the end of the first tapered section (120) decreases.

[0091] Accordingly, it is preferable that the angle formed at the point where the extension line in the longitudinal direction in which the first rail (110) extends and the extension line in the diagonal direction in which the first tapered portion (120) extends meet is greater than 5 degrees.

[0092] Additionally, referring to FIG. 10, the angle formed at the point where the extension line in the longitudinal direction in which the second rail (130) according to an embodiment of the present invention extends meets the extension line in the diagonal direction in which the second tapered portion (140) extends may be 5 to 20 degrees.

[0093] Referring to FIG. 7, the wheel (220) of the ceramic module (200) that contacts the first rail (110) and the second rail (130) may have a rectangular cross-section. In this case, the angle formed at the point where the extension line in the longitudinal direction of the first rail (110) and the extension line in the diagonal direction of the first tapered section (120) meet may be 5 to 20 degrees, and the angle formed at the point where the extension line in the longitudinal direction of the second rail (130) and the extension line in the diagonal direction of the second tapered section (140) meet may be 5 to 20 degrees.

[0094] However, the wheel (220) of the ceramic module (200) in contact with the first rail (110) and the second rail (130) is not limited to having a rectangular cross-section, and the wheel (220) of the ceramic module (200) may have a square cross-section.

[0095] Referring to FIG. 11, when the cross-section of the wheel (220) of the ceramic module (200) is square, the angle formed at the point where the extension line in the longitudinal direction where the first rail (110) according to the embodiment of the present invention extends meets the extension line in the diagonal direction where the first tapered portion (120) extends may be 5 to 55 degrees.

[0096] When the cross-section of the wheel (220) of the ceramic module (200) is square, the ceramic module (200) can move smoothly along the first tapered section (120) and the second tapered section (140) even when the angle formed at the point where the extension line in the longitudinal direction of the first rail (110) and the extension line in the diagonal direction of the first tapered section (120) meet is 45 degrees.

[0097] However, even in such cases, if the angle formed at the point where the extension line in the longitudinal direction in which the first rail (110) extends and the extension line in the diagonal direction in which the first tapered section (120) extends meet is greater than 55 degrees, the intersection angle of the joint surface formed by the first tapered section (120) and the second tapered section (140) in the direction in which the ceramic module (200) moves increases, and vibration may occur in the ceramic module (200).

[0098] Accordingly, when the cross-section of the wheel (220) of the ceramic module (200) is square, it is preferable that the angle formed at the point where the extension line in the longitudinal direction where the first rail (110) extends and the extension line in the diagonal direction where the first tapered portion (120) extends meet is less than 55 degrees.

[0099] In addition, even if the cross-section of the wheel (220) of the ceramic module (200) is square, if the angle formed at the point where the extension line in the longitudinal direction of the first rail (110) and the extension line in the diagonal direction of the first tapered section (120) meet is too small (less than 5 degrees), there is a risk of damage occurring at the end of the first tapered section (120) as the strength at the end of the first tapered section (120) decreases.

[0100] Accordingly, when the cross-section of the wheel (220) of the ceramic module (200) is square, it is preferable that the angle formed at the point where the extension line in the longitudinal direction where the first rail (110) extends and the extension line in the diagonal direction where the first tapered portion (120) extends meet is greater than 5 degrees.

[0101] In addition, when the cross-section of the wheel (220) of the ceramic module (200) is square, the angle formed at the point where the extension line in the longitudinal direction where the second rail (130) according to the embodiment of the present invention extends meets the extension line in the diagonal direction where the second tapered portion (140) extends may be 5 to 55 degrees.

[0102] The angle formed at the point where the extension line in the longitudinal direction where the first rail (110) is extended according to an embodiment of the present invention meets the extension line in the diagonal direction where the first tapered portion (120) is extended, and the angle formed at the point where the extension line in the longitudinal direction where the second rail (130) is extended meets the extension line in the diagonal direction where the second tapered portion (140) is extended, may be changed in the shape of the wheel (220) of the ceramic module (200).

[0103] Referring to FIGS. 4 and 5, a first step portion (113) may be provided on the side of the point where the first tapered portion (120) starts at one end of the first rail (110) according to an embodiment of the present invention. Additionally, a second step portion (133) may be provided on the side of the point where the second tapered portion (140) starts at the other end of the second rail (130).

[0104] According to an embodiment of the present invention, the first step portion (113) may contact the end of the second tapered portion (140), and the second step portion (133) may contact the end of the first tapered portion (120).

[0105] When the first rail (110) and the second rail (130) are joined through the first tapered section (120) and the second tapered section (140), if the first tapered section (120) and the second tapered section (140) are brought into contact without the first step section (113) and the second step section (133), the ends of the first tapered section (120) and the second tapered section (140) can be exposed to the outside.

[0106] If the ends of the first tapered section (120) and the second tapered section (140) are exposed to the outside, there is a risk that the ends of the first tapered section (120) and the second tapered section (140) will be damaged by the movement of the ceramic module (200).

[0107] To prevent this, a first step portion (113) that contacts the end of the second tapered portion (140) may be provided on the side of the point where the first tapered portion (120) starts at one end of the first rail (110). Additionally, a second step portion (133) that contacts the end of the first tapered portion (120) may be provided on the side of the point where the second tapered portion (140) starts at the other end of the second rail (130).

[0108] Referring to FIG. 6, a first chamfered portion (123) that is chamfered in a round shape may be provided on the upper surface of one end of the first tapered portion (120) according to an embodiment of the present invention. Additionally, a second chamfered portion (143) that is chamfered in a round shape may be provided on the upper surface of the other end of the second tapered portion (140).

[0109] Since the ends of the first tapered section (120) and the second tapered section (140) are thin, their strength may be low. Therefore, to prevent damage to the end of the first tapered section (120), the first chamfered section (123), which is chamfered in a round shape, may be provided on the upper surface of one end of the first tapered section (120). Additionally, the second chamfered section (143), which is chamfered in a round shape, may be provided on the upper surface of the other end of the second tapered section (140).

[0110] The ceramic module (200) according to an embodiment of the present invention may include the wheel (220) that moves along the first rail (110), the first tapered section (120), the second rail (130), and the second tapered section (140).

[0111] Referring to FIG. 7, the length of the first tapered section (120) or the second tapered section (140) according to an embodiment of the present invention may be the same as the length formed when the wheel (220) rotates one full turn. Specifically, the length of the first tapered section (120) or the second tapered section (140) may be the same as the length the wheel (220) travels when the wheel (220) rotates one full turn.

[0112] Here, the length of the first tapered section (120) or the second tapered section (140) may be the length in which the first tapered section (120) or the second tapered section (140) is extended in the longitudinal direction in which the first rail (110) and the second rail (130) are extended.

[0113] Specifically, the length of the first tapered section (120) or the second tapered section (140) may be the horizontal length of the first tapered section (120) or the second tapered section (140) in FIG. 7.

[0114] The length formed when the wheel (220) rotates one full turn may be the length traveled along the first rail (110), the first tapered section (120), the second rail (130), and the second tapered section (140) when the wheel (220) rotates one full turn while moving along the first rail (110), the first tapered section (120), the second rail (130), and the second tapered section (140).

[0115] According to an embodiment of the present invention, the length of the first tapered portion (120) or the second tapered portion (140) may be the same as the length formed when the wheel (220) rotates one full turn.

[0116] Referring to FIG. 7, as the length of the first tapered section (120) or the second tapered section (140) is equal to the length formed when the wheel (220) rotates one full turn, the right end of the wheel (220), the center point of the wheel (220), and the left end of the wheel (220) can move while coming into contact with one side point, the center point, and the other side point of the joining surface of the first tapered section (120) and the second tapered section (130).

[0117] Through this, the wheel (220) of the ceramic module (200) can move smoothly along the joining surface of the first tapered section (120) and the second tapered section (130).

[0118] The rail structure according to the embodiment of the present invention described above has the following effects.

[0119] The rail structure according to an embodiment of the present invention has the advantage of enabling a ceramic module to move smoothly on the rail by combining the first rail and the second rail through a first tapered portion provided on the first rail and a second tapered portion provided on the second rail.

[0120] In addition, the rail structure according to an embodiment of the present invention can improve the convenience of manufacturing by manufacturing the first rail and the second rail separately, and combining the first rail and the second rail while arranging the first tapered portion provided on the first rail and the second tapered portion provided on the second rail so that they face each other.

[0121] In addition, the rail structure according to the embodiment of the present invention has the advantage of being able to extend the rail in the longitudinal direction and easily form a curve in the rail by manufacturing the first rail and the second rail separately.

[0122] In addition, the rail structure according to an embodiment of the present invention has the advantage of being able to firmly fix the first rail and the second rail by coupling the first coupling projection and the first coupling groove provided on the side of the first rail to the second coupling groove and the second coupling projection provided on the side of the second rail.

[0123] In addition, the rail structure according to an embodiment of the present invention has the advantage of being able to firmly fix the first rail and the second rail by separating the first rail and the second rail into a part where the wheel of the ceramic module moves and a part where a gear is provided, and by providing a coupling projection and a coupling groove in the part where the gear is provided to connect the first rail and the second rail.

[0124] As such, the present invention has been described with reference to an embodiment illustrated in the drawings; however, this is merely illustrative, and those skilled in the art will understand that various modifications and variations of the embodiment are possible therefrom. Accordingly, the true scope of technical protection of the present invention should be determined by the technical spirit of the appended claims.
