Description

Technical Field

[0001] This utility model relates to a body care device, and more specifically to a body care device capable of providing massage through physical stimulation of the user's body.

[0002] Priority information

[0003] Korean Patent Application No.: 10-2024-0090403 (2024-07-09) Background Technology

[0004] In recent years, with the increasing aging of society, people of all ages, regardless of gender, are becoming more aware of the importance of health management, maintenance, and improvement. As a result, more and more people are utilizing medical facilities or other amenities such as sports clubs to manage, maintain, or enhance their health.

[0005] Furthermore, just as much as maintaining or improving health and physical strength, many people are simultaneously striving to recover from fatigue or eliminate stress. To this end, various body care devices, such as massage tools, have been developed and are widely used in daily life.

[0006] Massage is a type of adjunctive medical therapy that uses hands or special tools to sweep, knead, press, pull, pat, or move the body to promote blood circulation and relieve fatigue. Instruments that perform massage through mechanical devices are called massage tools, and various mechanical elements are used in massage tools to ensure effective massage.

[0007] Regarding the body care device that performs massage through a mechanical device as described above, Korean Patent No. 10-2496485 (hereinafter referred to as "Prior Document 1") discloses a detachable air stretching massage device that helps with the correct posture of the legs, pelvis, and waist.

[0008] Specifically, a body care device is disclosed, comprising: a main component having a massage space recessed from the upper side to the lower side; a central component assembled to be selectively detachable from the main component and dividing the massage space into two sub-spaces; an airbag device disposed on the main component and receiving a control signal to expand into the massage space; and a cushioning device disposed on the central component.

[0009] However, the body care device in existing document 1 has the following problem: it can only provide a massage with a simple action of tightening the user's legs from the left and right, and the massage is limited to the location where the airbag is set. That is, the limitation of the body care device in existing document 1 is that it cannot change the massage area and only uses air pressure for massage.

[0010] In addition, Korean Utility Model Publication No. 20-2023-0002125 (hereinafter referred to as "Prior Document 2") discloses a multifunctional massager.

[0011] Specifically, a body care device is disclosed, comprising: a foot massager including two sets of foot massage components disposed within a first housing to provide foot massage; and slots, two of which are arranged side by side within a second housing to accommodate the user's legs, wherein massage airbags are disposed within the slots.

[0012] However, the body care device in existing document 2 also has the following problem: it can only provide a massage with a simple action of tightening the user's legs from the left and right, and the massage is limited to the location where the airbag is set. That is, the limitation of the body care device in existing document 2 is that in order to change the massage area, the user needs to move the massager himself, and the massage is only performed using air pressure.

[0013] As mentioned above, in the case of body care devices that perform massage through mechanical means, there are issues that must be addressed in order to create a more suitable structure in terms of both effective massage and ease of use.

[0014] However, existing body care devices have limitations in adequately addressing this issue. Utility Model Content

[0061] Figure 1 This is a perspective view showing a body care device 1000 provided in one embodiment of the present invention. Figure 2 and Figure 3 It is shown illustratively. Figure 1 The diagram shows the working state of the body care device 1000. Figure 4 This is a diagram showing the spherical connector portion 600 driven along the ball guide groove portion 500 in a body care device 1000 provided in an embodiment of the present invention. Figure 5 This is a diagram showing the angular cam portion 300 and the massage arm portion 400 that are combined with the main rod portion 200 in a body care device 1000 provided in an embodiment of the present invention. Figure 6 This is a more detailed illustration of the portion where the cam cover 410 and the ball joint portion 600 are joined in a body care device 1000 provided in one embodiment of the present invention. Figures 7 to 9 This is an illustrative diagram showing how the various structures in a body care device 1000 provided in one embodiment of the present invention are driven as the main rod 200 rotates.

[0062] One embodiment of the present invention provides a body care device 1000 including a base portion 100, a main rod portion 200, an angled cam portion 300, a massage arm portion 400, a ball guide groove portion 500, and a ball joint portion 600.

[0063] The base portion 100 is the main body of the body care device 1000 provided in this embodiment. The main rod portion 200, the angled cam portion 300, the massage arm portion 400, the ball guide groove portion 500, and the ball joint portion 600 can all be driven to change position and configuration based on the base portion 100.

[0064] This 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.

[0065] Therefore, the user can drive the rest of the structure while bringing the massage target area close to the base 100, thereby achieving massage of that area.

[0066] The main rod 200 is configured to rotate about the rod rotation axis 201 that is transverse to the base 100, and can rotate by the rotational force generated by the drive unit 700.

[0067] The cam portion 300 is a portion that is connected to the main rod portion 200 in such a way that its cross section is not parallel to the virtual line and is penetrated by the main rod portion 200 and rotates together with the main rod portion 200. The virtual line is orthogonal to the rod rotation axis 201.

[0068] Specifically, the angular cam portion 300 can be combined with the main rod portion 200 in such a way that a plate-shaped cross section is penetrated by the main rod portion 200. Therefore, it can be combined into a shape in which the angular cam portion 300 protrudes from the outer peripheral surface of the main rod portion 200.

[0069] In particular, the plate-shaped cross section of the cam portion 300 can be configured as a virtual line that is not parallel to the axis of rotation of the rod 201.

[0070] That is, when viewing the angled cam portion 300 in its combined state with the main rod portion 200 from the main view, the angled cam portion 300 can be configured with an inclined plate-like cross-section instead of a vertical state. Furthermore, when viewing the angled cam portion 300 in its combined state with the main rod portion 200 from the top view, the angled cam portion 300 can also be configured with an inclined plate-like cross-section instead of a vertical state.

[0071] Therefore, when the main rod 200 rotates, the cam 300 can rotate at an angle.

[0072] For example, such as Figure 7 As shown, the portion of the angular cam portion 300 located at the upper part of the main rod portion 200 can be positioned to the right of the portion located at the lower part. Simultaneously, the position of the angular cam portion 300 can be configured such that the cross-section located on the left side faces the front more than the cross-section located on the right side.

[0073] In addition, such as Figure 8 and Figure 9 As shown, with the rotation of the main rod 200, the deflection cam 300 can be changed so that the portion disposed on the upper part of the main rod 200 is positioned to the left of the portion disposed on the lower part. At the same time, the deflection cam 300 can be changed so that the cross-section disposed on the right side faces the front more than the cross-section disposed on the left side.

[0074] The massage arm 400 is a part that is connected to the angle cam 300 in a manner constrained by the displacement of the angle cam 300 other than rotation, and can be driven in a configuration corresponding to the angle cam 300 as described above.

[0075] The ball guide groove 500 is a portion formed continuously in the transverse direction on the base portion 100, and can perform the function of a guide rail that enables the ball joint portion 600 to reciprocate in the transverse direction.

[0076] The spherical connector 600 is the part in which the other spherical end 602 is inserted into the ball guide groove 500 while the rod-shaped end 601 is combined with the massage arm 400, thus restricting the rotation of the massage arm 400 and enabling the massage arm 400 to reciprocate in the lateral direction.

[0077] According to the structure described above, when the main rod 200 rotates, the angular cam 300 can rotate at an angle. When this angular cam 300 rotates, the massage arm 400 can not only be driven in the left and right directions in a rotationally restricted state, but its upper and lower parts can also undergo relative displacement.

[0078] That is, the massage arm 400 can be driven from top to bottom along a wave-shaped movement path.

[0079] Therefore, the massage arm 400 does not only move back and forth in a specific part, but moves back and forth sequentially from top to bottom. From this point of view, it can achieve a driving force similar to the kneading of a human hand.

[0080] As described above, in a body care device 1000 provided in one embodiment of the present invention, the massage arm 400 is combined with the angular cam 300 disposed at an angle on the main rod 200. When the angular cam 300 rotates, the massage arm 400 is not only driven in the left and right direction, but its upper and lower parts also undergo relative displacement. Therefore, it can achieve a drive similar to the kneading of a human hand, further improving the massage effect.

[0081] In one embodiment of the present invention, the body care device 1000 may include a massage arm 400 and a massage body 420.

[0082] The cam cover 410 is a part that covers the angled cam portion 300 and can rotate in a manner that allows the angled cam portion 300 to slide inside. The massage arm portion 40 can receive the movement of the cam cover 410 other than rotation.

[0083] In this case, a separate bearing structure or the like may be provided at the part where the cam cover 410 contacts the cam section 300.

[0084] The massage body 420 is a portion that extends longitudinally from the end of the cam cover 410. The cam cover 410 can also apply physical stimulation generated by kneading drive to the massage target area through the movement of the angled cam portion 300 transmitted from it.

[0085] In particular, the massage body 420 extends longitudinally, thus enabling it to contact a certain area of ​​the massage target. Therefore, when the massage body 420 is activated, it can massage a certain area of ​​the massage target.

[0086] As described above, in a body care device 1000 provided in one embodiment of the present invention, the massage arm 400 includes a cam cover 410 and a massage body 420, thus enabling effective physical stimulation to a certain range of massage target areas.

[0087] In one embodiment of the present invention, the body care device 1000 may have a pair of angular cam portions 300 disposed on the main rod portion 200. In this case, the massage arm portion 400 may be disposed on each angular cam portion 300.

[0088] That is, when one main rod 200 rotates, the pair of angled cams 300 connected to it can rotate together. In addition, the massage arm 400, which is respectively disposed on each angled cam 300, can also be driven together.

[0089] As described above, in the body care device 1000 provided in one embodiment of the present invention, when a main rod 200 rotates, a pair of massage arms 400 are driven together, so that physical stimulation can be applied to the massage target area from both sides simultaneously.

[0090] In one embodiment of the present invention, a body care device 1000 is provided, in which a pair of angular cam portions 300 can be arranged symmetrically on the main rod portion 200.

[0091] That is, when one main rod 200 rotates, the pair of angled cams 300 coupled to it can rotate in a symmetrical manner. In addition, the massage arm 400 respectively disposed on each angled cam 300 can also be driven in a symmetrical manner.

[0092] Therefore, when the massage target is positioned between a pair of massage arms 400, symmetrical physical stimulation can be applied from both sides of the target, thereby achieving a more effective massage.

[0093] As described above, in the body care device 1000 provided in one embodiment of the present invention, a pair of massage arms 400 driven together are driven in a symmetrical manner, thus enabling more effective physical stimulation to be applied to both sides of the massage target area.

[0094] In one embodiment of the present invention, the body care device 1000 may further include a guide bushing 430, which is disposed at the portion of the cam cover 410 that engages with the ball joint portion 600 to change the insertion depth of one end 601 of the ball joint portion 600.

[0095] As described above, when the cam portion 300 rotates, the ball joint portion 600 can reciprocate laterally. However, when the ball guide groove portion 500 for inserting into the ball joint portion 600 is formed in a straight line shape laterally, the ball joint portion 600 may be difficult to reciprocate because the interval between the massage arm portion 400 and the ball guide groove portion 500 is partially different from each other.

[0096] Therefore, in order to make the ball joint 600 reciprocate smoothly, it is advisable to form the ball guide groove 500 into an arc shape instead of a straight shape. However, when the ball joint 600 is inserted into such an arc-shaped ball guide groove 500, a certain part of the massage arm 400 is also driven into an arc shape, which may not be preferred.

[0097] Therefore, when the intervals between the massage arm portion 400 and the ball guide groove portion 500 are somewhat different from each other, such as Figure 6 As shown, by changing the insertion depth of one end 601 of the ball joint 600 by the guide bushing 430, even if the ball guide groove 500 is formed into a straight shape in the transverse direction, it is possible to avoid hindering the reciprocating motion of the ball joint 600.

[0098] As described above, in the body care device 1000 provided in one embodiment of the present invention, the depth to which one end 601 of the ball joint portion 600 is inserted is changed by the guide bushing 430 provided on the cam cover 410, so that even if the ball guide groove portion 500 is formed in a straight shape, the ball joint portion 600 can be smoothly driven.

[0099] In one embodiment of the present invention, the body care device 1000 may have an inner diameter of guide bushing 430 that corresponds to the outer diameter of one end 601 of ball joint portion 600.

[0100] As described above, when one end 601 of the ball joint portion 600 is inserted into the guide bushing 430, displacement of the ball joint portion 600 other than in the length direction can be preferably restricted.

[0101] That is, it is preferable to allow one end 601 of the ball joint portion 600 to move only along the length direction within the guide bushing 430, while minimizing the clearance between the guide bushing 430 and one end 601 of the ball joint portion 600 in other directions.

[0102] As described above, in the body care device 1000 provided in one embodiment of the present invention, the outer diameter of one end 601 of the ball joint portion 600 corresponds to the inner diameter of the guide bushing 430, so that one end 601 of the ball joint portion 600 inserted into the guide bushing 430 can be effectively driven only in the length direction.

[0103] Figure 10 This is a diagram showing the rack 101 and pinion 401 in a body care device 1000 provided in one embodiment of the present invention.

[0104] In one embodiment of the present invention, the body care device 1000 is configured to be able to move up and down relative to the base portion 100 along the longitudinal direction.

[0105] That is, such as Figures 1 to 3 As shown, the massage arm 400 can move up and down longitudinally while massaging the massage target at different heights.

[0106] For example, not only the user's calves, but also the thighs can be massaged by the massage arm 400 moving up and down longitudinally.

[0107] As described above, in the body care device 1000 provided in one embodiment of the present invention, the massage arm 400 is configured to be able to move up and down longitudinally along the base 100, thus enabling the massage target area to be changed automatically for more convenient massage.

[0108] In one embodiment of the present invention, the body care device 1000 may have a rack 101 arranged longitudinally on the base portion 100. In this case, the massage arm portion 400 may be provided with a pinion 401 capable of meshing with the rack 101.

[0109] Therefore, as Figure 10 As shown, when the pinion 401 rotates, the rack 101 can rise and fall together with the pinion 401, and the massage arm 400 coupled with the pinion 401 can rise and fall along the longitudinal direction of the base 100.

[0110] As described above, in a body care device 1000 provided in one embodiment of the present invention, a rack 101 is provided in the base portion 100 and a pinion 401 is provided in the massage arm portion 400, thereby enabling the massage arm portion 400 to rise and fall more precisely and stably.

[0111] One embodiment of the present invention provides a body care device 1000 that may further include a drive unit 700, which causes the main rod 200 to rotate about the rod rotation axis 201. In this case, the drive unit 700 may be configured to cause the pinion 401 to rotate together with the rotation of the main rod 200.

[0112] Here, the drive unit 700 may include a drive motor and drive gears, etc.

[0113] That is, such as Figure 10 As shown, a drive unit 700 can be connected to both 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 from the drive unit 700.

[0114] Therefore, compared to the structure in which separate drive units 700 are provided in the main rod 200 and the pinion 401, a simplified structure can be constructed.

[0115] As described above, in the body care device 1000 provided in one embodiment of the present invention, the rotation of the main rod 200 and the rotation of the pinion 401 are simultaneously achieved by a single drive unit 700, thus the overall structure can be further simplified by minimizing the number of drive units 700.

[0116] On the other hand, in the body care device 1000 provided in this embodiment, it can also be configured as needed to drive only the main rod 200 by the drive unit 700 which is separate from the pinion 401, so that massage can be performed when the massage arm 400 is not raised or lowered.

[0117] In one embodiment of the present invention, the body care device 1000 may further include an elastic body 440, which is disposed on the outer surface of the massage body 420 and is capable of elastic deformation.

[0118] When a massage is performed by the massage arm 400 in contact with the user's massage target area, pain may be caused to the user due to problems such as pressure being concentrated in a specific area.

[0119] Therefore, it is preferable to provide an elastomer 440 on the outer surface of the massage body 420 to appropriately disperse pressure when pressure is concentrated in a specific area.

[0120] As described above, in a body care device 1000 provided in one embodiment of the present invention, an elastic body 440 capable of elastic deformation is provided on the outer surface of the massage body 420 of the massage arm 400, thereby buffering a portion of the pressure inappropriately applied to the massage target area.

[0121] In one embodiment of the present invention, the body care device 1000 may be composed of an airbag 441 that can adjust the degree of air injection.

[0122] When the massage arm 400 is in contact with the user's massage target area to perform a massage, some users may feel that the applied pressure is too strong, while others may feel that the applied pressure is too weak.

[0123] In this way, even when performing a massage with the same pressure, the user will have different feelings about the pressure intensity depending on their characteristics. From this point of view, it is preferable that each user can use the massage while adjusting the air injection level of the airbag 441 located on the outer surface of the massage body 420.

[0124] As described above, in the body care device 1000 provided in one embodiment of the present invention, the elastomer 440 is composed of an airbag 441, so the pressure applied to the massage target can be adjusted by adjusting the air pressure.

[0125] In a body care device 1000 provided in one embodiment of the present invention, the elastomer 440 may be configured to have a concave-convex surface formed on the outer surface of the massage body 420.

[0126] As mentioned above, an elastomer 440 can be provided to cushion a portion of the pressure that is inappropriately applied to the massage target area. However, in order to cushion the pressure more effectively, it is necessary to ensure that such an elastomer 440 has sufficient space to elastically deform.

[0127] Therefore, it is preferable to form the elastomer 440, which is in direct contact with the user's massage target area, into a concave-convex structure to ensure that the elastomer 440 has sufficient space to deform under pressure.

[0128] As described above, in a body care device 1000 provided in one embodiment of the present invention, the outer surface of the massage body 420 provided with the elastomer 440 is composed of a concave-convex surface, thus ensuring additional space for the elastomer 440 to be deformed under pressure.

[0129] Figure 11 and Figure 12 This is a more detailed diagram showing the portion of the body care device 1000 provided in one embodiment of the present invention where the massage body 420 is joined to the cam cover 410.

[0130] In one embodiment of the body care device 1000 provided by this utility model, the massage body 420 can be hinged to the end of the cam cover 410. That is, as Figure 11 and Figure 12 As shown, the massage body 420 can be hinged to rotate at the end of the cam cover 410.

[0131] When the massage arm 400 is in contact with the user's massage target area to perform a massage, some users have thinner legs and may not feel any burden when using it, but other users have thicker legs and may not be compatible with the configuration of the massage arm 400.

[0132] Therefore, the massage arm 400 can preferably be hinged to rotate according to the body characteristics of each user to achieve an appropriate configuration, thereby enabling more types of users to receive massage without any burden.

[0133] As described above, in the body care device 1000 provided in one embodiment of the present invention, a massage body 420 is hinged to the end of the cam cover 410. Therefore, when massaging users with different body characteristics, the configuration of the massage arm 400 can be adjusted according to the massage target area of ​​each user.

[0134] In one embodiment of the present invention, the body care device 1000 may further include a torsion spring 450, which is disposed at the end of the massage body 420 and the cam cover 410.

[0135] As described above, even if the massage arm 400 is hinged and rotated to achieve an appropriate configuration according to each user's body characteristics, users with thinner legs may experience a weaker massage intensity due to the relatively larger gap between them. Conversely, users with thicker legs may experience a stronger massage intensity due to the relatively smaller gap between them.

[0136] Therefore, by introducing a torsion spring 450 at the joint between the massage body 420 and the cam cover 410, additional pressure corresponding to the rigidity of the torsion spring 450 can be applied to users with thinner legs. Furthermore, for users with thicker legs, the massage intensity can be appropriately limited to prevent the massage arm 400 from excessively rotating due to the torsion spring 450.

[0137] As described above, the body care device 1000 provided in one embodiment of the present invention appropriately adjusts the hinge rotation of the massage body 420 by means of a torsion spring 450, so that when massaging users with different body characteristics, the massage arm 400 can be appropriately contacted with the massage target area of ​​each user.

[0138] The specific embodiments of this utility model have been described and illustrated above. However, this utility model is not limited to the described embodiments. It will be obvious to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of this utility model. Therefore, such modifications or variations should not be understood separately from the technical concept or viewpoint of this utility model, and the modified embodiments should fall within the scope of the claims of this utility model.
