Description

Technical Field

[0001] This disclosure relates to a body care device, and more specifically to a body care device capable of providing massage by physically stimulating the body of a seated user. Background Technology

[0002] In recent years, with the aging of society, people of all ages have become increasingly aware of healthcare, health maintenance, and health promotion. As a result, many people are utilizing facilities such as medical facilities or sports clubs to manage, maintain, or improve their health.

[0003] In addition to maintaining or improving health and physical fitness, many people also try to relieve fatigue and stress. For this purpose, various body care devices, such as massage devices, have been developed and are widely used in daily life.

[0004] Massage is a medical adjunct therapy that involves using hands or specialized equipment to push, knead, press, pull, tap, or move the body to improve blood circulation and relieve fatigue. Devices that perform massage using mechanical equipment are called massage devices, and various mechanical components are used in massage devices for effective massage.

[0005] Regarding body care devices that use mechanical equipment for massage, Korean Patent No. 10-2496485 (hereinafter referred to as "Prior Art Document 1") discloses a detachable air stretching massage device for assisting in the correct posture of the legs, pelvis and waist.

[0006] Specifically, a main component is disclosed having: a massage space recessed from above in a downward direction; a central component selectively and removably assembled to the main component and configured to divide the massage space into two sub-spaces; an airbag device disposed at the main component and configured to inflate into the massage space upon receiving a control signal; and a buffer device disposed at the central component.

[0007] However, the body care device in prior art document 1 has the following problems: it only provides massage by compressing the user's legs from the left and right sides through simple operation, and the massage is limited to the location where the air bag is installed. In other words, the body care device in prior art document 1 has the following limitations: it does not change the area to be massaged, and it only uses air pressure to perform the massage.

[0008] Korean Utility Model Application Publication No. 20-2023-0002125 (hereinafter referred to as "Prior Art Document 2") discloses a multifunctional massager.

[0009] Specifically, a foot massage device is disclosed, which includes two sets of foot massage components installed in a first housing to provide foot massage and two slots arranged side by side in a second housing to receive the user's legs, and each slot has a massage air bag disposed therein.

[0010] However, the body care device in prior art document 2 also has the following problems: it only provides massage by compressing the user's legs from the left and right sides through simple operation, and the massage is limited to the location where the air bag is installed. That is to say, the body care device in prior art document 2 has the following limitations: the user must move the massager himself to change the area to be massaged, and the massage is performed using only air pressure.

[0011] As mentioned above, body care devices that use mechanical equipment for massage have issues that need to be addressed in order to achieve a more suitable structure in terms of both effective massage and ease of use.

[0012] However, traditional body care devices have limitations in fully addressing these issues. Summary of the Invention

Detailed Implementation

[0036] The preferred embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. In describing this disclosure, detailed descriptions may be omitted when it is determined that a detailed description of the relevant known art unnecessarily obscures the essential points of this disclosure.

[0037] In the embodiments of this disclosure, the X, Y, and Z directions can be orthogonal to each other. Both the X and Y directions can be parallel to the horizontal direction, while the Z direction can be parallel to the vertical direction. When the X direction is parallel to the left-right direction, the Y direction can be parallel to the front-back direction. When the X direction is parallel to the front-back direction, the Y direction can be parallel to the left-right direction.

[0038] Figure 1 This is a perspective view showing a body care device 1000 according to an embodiment of the present disclosure. Figure 2 and Figure 3 It is shown Figure 1 A view showing the operation of the body care device 1000. Figure 4 This is a view showing the ball joint portion 600 driven along the ball guide groove portion 500 in the body care device 1000 according to an embodiment of the present disclosure. Figure 5 This is a view showing the tilting cam portion 300 and the massage arm portion 400 connected to the main rod portion 200 in a body care device 1000 according to an embodiment of the present disclosure. Figure 6 This is a more detailed view of the portion in which the cam cover 410 and the ball joint portion 600 are connected to each other in a body care device 1000 according to an embodiment of the present disclosure. Figures 7 to 9 This is a view showing how the components in the body care device 1000 according to an embodiment of the present disclosure are driven by the rotation of the main rod 200.

[0039] The body care device 1000 according to an embodiment of the present disclosure includes a base portion 100, a main rod portion 200, an inclined cam portion 300, a massage arm portion 400, a ball guide groove portion 500, and a ball joint portion 600.

[0040] The base portion 100 is the main body of the body care device 1000 according to this embodiment, and the main rod portion 200, the tilting cam portion 300, the massage arm portion 400, the ball guide groove portion 500 and the ball joint portion 600 can all be driven while their positions and arrangements change relative to the base portion 100.

[0041] The base portion 100 can be part of a massage device (such as a massage chair). Furthermore, the base portion 100 can be formed independently to minimize relative movement.

[0042] Therefore, the user can move the area to be massaged to the base 100 and drive the remaining components to massage the area.

[0043] The main rod portion 200 is a portion that is installed to be able to rotate around the rod rotation axis 201 in the lateral direction of the base portion 100, and can be rotated around the axis by the rotational force generated by the driver 700.

[0044] The tilting cam portion 300 is configured such that the main rod portion 200 extends through and connects to a cross section of the tilting cam portion 300 that is not parallel to an imaginary line orthogonal to the rod rotation axis 201, thereby rotating together with the main rod portion 200.

[0045] Specifically, the main rod portion 200 can extend through and connect to the plate-shaped cross-section of the inclined cam portion 300. Therefore, the inclined cam portion 300 can be connected to the main rod portion 200 so as to protrude from the outer peripheral surface of the main rod portion 200.

[0046] In particular, the plate-shaped cross section of the inclined cam portion 300 can be configured to be non-parallel to an imaginary line orthogonal to the rod rotation axis 201.

[0047] In other words, when the inclined cam portion 300 connected to the main rod portion 200 is viewed from the front, the plate-shaped cross-section of the inclined cam portion 300 can be set at an angle (or tilted) instead of being vertical. In addition, even when the inclined cam portion 300 connected to the main rod portion 200 is viewed from above, the plate-shaped cross-section of the inclined cam portion 300 can be set at an angle (or tilted) instead of being vertical.

[0048] Therefore, when the main rod 200 rotates around the axis, the tilting cam 300 can rotate at an angle.

[0049] For example, such as Figure 7 As shown, the tilting cam portion 300 can be configured such that the portion located above the main rod portion 200 is positioned further to the right than the portion located below the main rod portion. Simultaneously, the tilting cam portion 300 can be configured such that its section on the left side is more forward-oriented than its section on the right side.

[0050] like Figure 8 and Figure 9 As shown, the tilting cam 300 can be modified so that, depending on the rotation of the main rod 200, the portion of the tilting cam 300 positioned above the main rod 200 is positioned further to the left than the portion positioned below the main rod. Simultaneously, the tilting cam 300 can be modified so that its right-side section is more forward-oriented than its left-side section.

[0051] The massage arm 400 is connected to the tilt cam 300 and is constrained to not make any other displacement except to rotate with the tilt cam 300, and can be driven to a position corresponding to the tilt cam 300 according to the drive of the tilt cam 300.

[0052] The ball guide groove 500 is a portion continuously formed in the base portion 100 in the transverse direction and can be used as a track along which the ball joint portion 600 can reciprocate in the transverse direction.

[0053] The ball joint portion 600 is configured such that one rod-shaped end 601 is connected to the massage arm portion 400 and its other spherical end 602 is inserted into the ball guide groove portion 500, and can allow the massage arm portion 400 to reciprocate in the lateral direction while restricting its rotation.

[0054] In the above structure, the tilting cam 300 can rotate at an angle / tilt when the main rod 200 rotates about its axis. When the tilting cam 300 rotates, it not only drives the massage arm 400 in the left-right direction with limited rotation, but also generates relative displacement between its upper and lower parts.

[0055] In other words, the massage arm 400 can be driven by a wave-like motion from top to bottom.

[0056] Therefore, the massage arm 400 can be driven in a similar way to a human hand, because only a certain part of it does not move back and forth, but the massage arm 400 moves back and forth from top to bottom.

[0057] Thus, in the body care device 1000 according to the embodiments of the present disclosure, the massage arm 400 is connected to the inclined cam 300 which is angled / tiltedly disposed on the main rod 200. Therefore, when the inclined cam 300 rotates, it not only drives the massage arm 400 in the left and right directions, but also generates a relative displacement between its upper and lower parts, thereby achieving an experience similar to hand kneading, which can further improve the massage effect.

[0058] In the body care device 1000 according to an embodiment of the present disclosure, the massage arm 400 may include a cam cover 410 and a massage body 420.

[0059] The cam cover 410 is the part that covers the tilt cam portion 300 and allows the tilt cam portion 300 to rotate therein when sliding, and can transmit motion other than the rotation of the cam cover 410 to the massage arm portion 400.

[0060] In this case, separate bearing structures can be provided at the points where the cam cover 410 and the inclined cam portion 300 contact each other.

[0061] The massage body 420 is a portion mounted on the end of the cam cover 410 to extend in the longitudinal direction, and can apply physical stimulation to the area to be massaged due to the movement of the inclined cam portion 300 transmitted to the cam cover 410.

[0062] Specifically, since the massage body 420 is installed to extend in the longitudinal direction, it can come into contact with the area to be massaged to a certain extent. Therefore, when the massage body 420 is activated, a certain range of the area to be massaged can be massaged.

[0063] Therefore, in the body care device 1000 according to the embodiments of the present disclosure, since the massage arm 400 includes a cam cover 410 and a massage body 420, physical stimulation can be effectively applied within a certain range of the area to be massaged.

[0064] In the body care device 1000 according to an embodiment of the present disclosure, tilting cam portions 300 may be provided in pairs on the main rod portion 200. In this case, massage arm portions 400 may be provided on each tilting cam portion 300.

[0065] In other words, when one main rod 200 rotates around its axis, a pair of tilting cams 300 connected to it can also rotate. The massage arm 400 provided on each tilting cam 300 can also be driven.

[0066] Therefore, in the body care device 1000 according to the embodiments of the present disclosure, since a pair of massage arms 400 are driven together when one main rod 200 rotates, physical stimulation can be applied to the area to be massaged from both sides simultaneously.

[0067] In the body care device 1000 according to an embodiment of the present disclosure, a pair of inclined cam portions 300 may be symmetrically arranged on the main rod portion 200.

[0068] In other words, when one main rod 200 rotates around an axis, the pair of inclined cams 300 connected to it can rotate symmetrically. The massage arms 400, which are respectively provided on the inclined cams 300, can also be driven symmetrically.

[0069] Therefore, when the area to be massaged is located between a pair of massage arms 400, symmetrical physical stimulation can be applied to both sides of the area, resulting in a more effective massage.

[0070] Therefore, in the body care device 1000 according to the embodiments of the present disclosure, a pair of massage arms 400 driven together are driven in a symmetrical state, and thus more effective physical stimulation can be applied to both sides of the area to be massaged.

[0071] In the body care device 1000 according to an embodiment of the present disclosure, the massage arm 400 may further include a guide bushing 430, which is mounted on the portion of the cam cover 410 connected to the ball joint 600, such that the insertion depth of one end 601 of the ball joint 600 is variable.

[0072] As described above, the ball joint portion 600 can reciprocate in the lateral direction when the tilting cam portion 300 rotates. However, if the ball guide groove portion 500 into which the ball joint portion 600 is inserted is formed linearly in the lateral direction, the distance between the massage arm portion 400 and the ball guide groove portion 500 may be partially different from each other, making it difficult to reciprocate the ball joint portion 600.

[0073] Therefore, it is possible to form the ball guide groove 500 in an arc shape rather than a linear shape so that the ball joint 600 can perform smooth reciprocating motion. However, if the ball joint 600 is inserted into the arc-shaped ball guide groove 500, the massage arm 400 may also be driven in an arc shape to some extent, which may be undesirable.

[0074] Therefore, when the distances between the massage arm portion 400 and the ball guide groove portion 500 are partially different from each other, the insertion depth of one end 601 of the ball connector portion 600 can be adjusted by means of... Figure 6 The variation of the guide bushing 430 shown ensures that the reciprocating motion of the ball joint 600 is not hindered even though the ball guide groove 500 is formed linearly in the lateral direction.

[0075] Therefore, in the body care device 1000 according to the embodiments of the present disclosure, the insertion depth of one end 601 of the ball joint 600 is variable by means of the guide bushing 430 installed in the cam cover 410, so that the ball joint 600 can be smoothly driven even if the ball guide groove 500 is formed linearly.

[0076] In the body care device 1000 according to an embodiment of the present disclosure, the inner diameter of the guide bushing 430 may correspond to the outer diameter of one end 601 of the ball joint portion 600.

[0077] As described above, when one end 601 of the ball joint 600 is inserted into the guide bushing 430, it may be desirable to restrict the displacement of the ball joint 600 other than the displacement in the longitudinal direction.

[0078] In other words, it may be desirable that one end 601 of the ball joint 600 moves only in the longitudinal direction within the guide bushing 430, and that the gap between the guide bushing 430 and one end 601 of the ball joint 600 is minimized in other directions.

[0079] Therefore, in the body care device 1000 according to the embodiments of the present disclosure, the outer diameter of one end 601 of the ball joint portion 600 and the inner diameter of the guide bushing 430 correspond to each other, thereby allowing the ball joint portion 601 inserted into the guide bushing 430 to be effectively driven only in the longitudinal direction.

[0080] Figure 10This is a view showing the rack 101 and pinion 401 in a body care device 1000 according to an embodiment of the present disclosure.

[0081] In the body care device 1000 according to an embodiment of the present disclosure, the massage arm 400 can move upward and downward relative to the base 100 in the longitudinal direction.

[0082] In other words, such as Figures 1 to 3 As shown, the massage arm 400 can move up and down in the longitudinal direction to massage the area to be massaged at different heights.

[0083] For example, the massage arm 400 can move up and down in the longitudinal direction to massage the user's calves and thighs.

[0084] Thus, in the body care device 1000 according to the embodiments of the present disclosure, the massage arm 400 can move up and down in the longitudinal direction of the base 100, thereby making it easier to automatically change and massage the area to be massaged.

[0085] In the body care device 1000 according to an embodiment of the present disclosure, the base portion 100 may have a rack 101 mounted thereon in the longitudinal direction. In this case, the massage arm portion 400 may have a pinion 401 that can engage with the rack 101.

[0086] Therefore, as Figure 10 As shown, when the pinion 401 rotates, the rack 101 can move up and down along the pinion 401, and the massage arm 400 connected to the pinion 401 can move up and down in the longitudinal direction of the base 100.

[0087] Therefore, in the body care device 1000 according to the embodiments of the present disclosure, the rack 101 is mounted at the base portion 100 and the pinion 401 is mounted at the massage arm portion 400, thereby the massage arm portion 400 can move up and down more accurately and stably.

[0088] The body care device 1000 according to an embodiment of the present disclosure may further include a driver 700 configured to rotate the main rod 200 about the rod rotation axis 201. In this case, the driver 700 can utilize the rotation of the main rod 200 to rotate the pinion 401.

[0089] Here, the driver 700 may include a drive motor and a drive gear.

[0090] In other words, such as Figure 10As shown, a driver 700 can be connected to the main rod 200 and the pinion 401, so that the main rod 200 and the pinion 401 can rotate together by the rotational force transmitted by the driver 700.

[0091] Therefore, a simpler structure can be provided than one in which the individual drive 700 is respectively located at the main rod 200 and the pinion 401.

[0092] Therefore, in the body care device 1000 according to the embodiments of the present disclosure, the main rod 200 and the pinion 401 rotate together by a driver 700, thereby further simplifying the overall structure by minimizing the number of drivers 700.

[0093] Meanwhile, in the body care device 1000 according to this embodiment, the driver 700, which is separate from the pinion 401, drives the main rod 200 only as needed, thereby enabling massage to be performed without the massage arm 400 moving up or down.

[0094] In the body care device 1000 according to an embodiment of the present disclosure, the massage arm 400 may further include an elastomer 440, which is mounted on the outer surface of the massage body 420 to be elastically deformable.

[0095] When a massage is performed with the massage arm 400 in contact with the user's area to be massaged, there is a concern that the massage arm may cause pain to the user due to issues such as pressure being concentrated on specific areas.

[0096] Therefore, it may be desirable to mount the elastomer 440 on the outer surface of the massage body 420 so as to properly distribute pressure when pressure is concentrated on a particular part.

[0097] Thus, in the body care device 1000 according to the embodiments of the present disclosure, an elastically deformable elastomer 440 is mounted on the outer surface of the massage body 420 of the massage arm 400, thereby cushioning to some extent the pressure inappropriately applied to the area to be massaged.

[0098] In the body care device 1000 according to an embodiment of the present disclosure, the elastomer 440 may include an air bag 441 having an adjustable air injection level.

[0099] When a massage is performed with the massage arm 440 in contact with the user's area to be massaged, some users may feel that the applied pressure is too strong, while others may feel that the applied pressure is too weak.

[0100] Since users may have different sensations about pressure intensity even when performing a massage at the same pressure, it may be desirable to allow each user to adjust the inflation level of the safety airbag 441 mounted on the outer surface of the massage body 420.

[0101] Therefore, in the body care device 1000 according to an embodiment of the present disclosure, the elastomer 440 includes an air bag 441, thereby adjusting the pressure applied to the area to be massaged by adjusting the air pressure.

[0102] In the body care device 1000 according to an embodiment of the present disclosure, an elastomer 440 may be mounted on the outer surface of the massage body 420 to form an uneven / rough surface.

[0103] As mentioned above, the elastomer 440 can be installed to provide some cushioning against pressure that is inappropriately applied to the area to be massaged, but for more effective pressure cushioning, sufficient space needs to be ensured for the elastomer 440 to elastically deform.

[0104] Therefore, it may be desirable to form an elastomer 440 that is in direct contact with the user's area to be massaged, so as to have an uneven (rough) structure, thereby ensuring sufficient space for the elastomer 440 to deform under pressure.

[0105] Thus, in the body care device 1000 according to the embodiments of the present disclosure, the outer surface of the massage body 420 on which the elastomer 440 is mounted is uneven, thereby ensuring additional space for the elastomer 440 to deform under pressure.

[0106] Figure 11 and Figure 12 This is a more detailed view of the portion in which the massage body 420 and the cam cover 410 are connected to each other in a body care device 1000 according to an embodiment of the present disclosure.

[0107] In the body care device 1000 according to an embodiment of the present disclosure, the massage body 420 can be hingedly connected to the end of the cam cover 410. That is, as Figure 11 and Figure 12 As shown, the massage body 420 can be hingedly rotated at the end of the cam cover 410.

[0108] When a massage is performed with the massage arm 400 in contact with the user's area to be massaged, some users with thinner legs may receive the massage without difficulty, but other users with thicker legs may find it difficult to use the massage arm 400.

[0109] Therefore, it may be desirable to allow the massage arm 400 to pivot and be positioned appropriately according to each user's body characteristics, thereby allowing a wider range of users to receive a massage without difficulty.

[0110] Therefore, in the body care device 1000 according to the embodiments of the present disclosure, the massage body 420 is hinged to the end of the cam cover 410, so that when a user with different body characteristics receives a massage, the placement of the massage arm 400 can be adjusted to correspond to the area to be massaged for each user.

[0111] In the body care device 1000 according to an embodiment of the present disclosure, the massage arm 400 may further include a torsion spring 450 disposed at the portion where the massage body 420 is connected to the end of the cam cover 410.

[0112] As described above, even if the massage arm 400 is hinged and properly positioned according to each user's body characteristics, users with thinner legs may feel a weaker massage intensity due to the relatively large amount of empty space. Conversely, users with thicker legs may feel a stronger massage intensity due to the relatively small amount of empty space.

[0113] Therefore, the torsion spring 450 can be provided at the connection between the massage body 420 and the cam cover 410, and due to the stiffness of the torsion spring 450, additional pressure can be applied to users with thinner legs. In addition, for users with thicker legs, the massage intensity can be appropriately limited by preventing the massage arm 400 from excessively hinged rotation through the torsion spring 450.

[0114] Therefore, in the body care device 1000 according to the embodiments of the present disclosure, the hinge rotation of the massage body 420 can be appropriately adjusted by the torsion spring 450, so that the massage arm 400 can appropriately contact the area to be massaged of each user when massaging users with different body characteristics.

[0115] While the foregoing has been given by way of illustrative examples in this disclosure, all such modifications and other alterations that are obvious to those skilled in the art are considered to fall within the broad scope and range of this disclosure as set forth herein. Therefore, such modifications or variations should not be considered as departing from the spirit or scope of this disclosure, and this disclosure is intended to cover modifications and variations of the invention as long as they fall within the scope of the appended claims and their equivalents.

[0116] Industrial applicability

[0117] According to at least one embodiment of this disclosure, the massage arm is connected to an inclined cam portion that is inclinedly disposed on the main rod portion. Therefore, when the inclined cam portion is rotated, the massage arm is not only driven in the left and right direction, but also a relative displacement of its upper and lower parts is generated, thereby achieving an experience similar to human hand kneading, which can further improve the massage effect.

[0118] Furthermore, according to at least one embodiment of this disclosure, since the massage arm includes a cam cover and a massage body, physical stimulation can be effectively applied within a certain range of the area to be massaged.

[0119] Furthermore, according to at least one embodiment of this disclosure, since a pair of massage arms are driven together when one main rod rotates, physical stimulation can be applied to the area to be massaged from both sides simultaneously.

[0120] Furthermore, according to at least one embodiment of this disclosure, a pair of massage arms driven together are driven in a symmetrical manner, thus allowing for more effective physical stimulation to be applied to both sides of the area to be massaged.

[0121] Furthermore, according to at least one embodiment of this disclosure, the insertion depth of one end of the ball joint is variable by a guide bushing installed in the cam cover, thereby allowing the ball joint to be smoothly driven even if the ball guide groove is formed linearly.

[0122] Furthermore, according to at least one embodiment of this disclosure, the outer diameter of one end of the ball joint and the inner diameter of the guide bushing correspond to each other, thereby one end of the ball joint inserted into the guide bushing can be effectively driven only in the longitudinal direction.

[0123] Furthermore, according to at least one embodiment of this disclosure, the massage arm can move upward and downward in the longitudinal direction of the base, thereby automatically changing and more conveniently massaging the area to be massaged.

[0124] Furthermore, according to at least one embodiment of this disclosure, a rack is mounted at the base portion and a pinion is mounted at the massage arm portion, thereby allowing the massage arm portion to move up and down more precisely and stably.

[0125] Furthermore, according to at least one embodiment of this disclosure, the main shaft and the pinion rotate together via a single driver, thereby further simplifying the overall structure by minimizing the number of drivers.

[0126] Furthermore, according to at least one embodiment of the present invention, an elastically deformable elastomer is mounted on the outer surface of the massage body of the massage arm, thereby enabling it to buffer, to a certain extent, the pressure inappropriately applied to the area to be massaged.

[0127] Furthermore, according to at least one embodiment of this disclosure, the elastomer includes an air bag, thereby adjusting the pressure applied to the area to be massaged by adjusting the air pressure.

[0128] Furthermore, according to at least one embodiment of this disclosure, the outer surface of the massage body on which the elastomer is mounted is uneven, thereby ensuring additional space for the elastomer to deform under pressure.

[0129] Furthermore, according to at least one embodiment of this disclosure, the massage body is hinged to the end of the cam cover, thereby allowing the placement of the massage arm to be adjusted to correspond to the massage area of ​​each user when a user with different body characteristics receives a massage.

[0130] Furthermore, according to at least one embodiment of this disclosure, the hinge rotation of the massage body can be appropriately adjusted by a torsion spring, thereby allowing the massage arm to appropriately contact the area to be massaged for each user when performing a massage on users with different body characteristics.
