Description

Technical Field

[0001] This utility model relates to body care devices, and more specifically, to body care devices capable of providing massage by physically stimulating the user's body.

[0002] This utility model claims priority to Korean Patent Application KR10-2024-0093012 (July 15, 2024). Background Technology

[0003] Recently, with the aging of society, people of all ages and genders are becoming increasingly aware of the importance of health management, maintenance, and promotion. As a result, many people are using facilities such as medical facilities or gyms to manage, maintain, or promote their health.

[0004] In addition to maintaining or promoting health and physical strength, people also make many efforts to recover from fatigue or relieve stress. As a result, various body care devices, such as massage tools, have been developed and are widely used in daily life.

[0005] Massage is a complementary medical therapy that uses hands or special tools to sweep, knead, press, pull, pat, and move the body to help blood circulation and relieve fatigue. Instruments that perform massage based on mechanical devices are called massage devices, and various mechanical components are used in massage devices to ensure effective massage.

[0006] Regarding a body care device that performs massage via the mechanical means described above, Korean Patent Publication No. 10-2023-0061714 (hereinafter referred to as 'Prior Document') discloses a back-head massage device.

[0007] Specifically, the following components are disclosed: a housing, at least a portion of which rests on and supports the back of the user's head on its upper surface; a pressurizing unit, at least a portion of which moves up and down within the housing and applies pressure to the back of the user's head in a predetermined pressure or pattern; and a lifting adjustment unit, which is disposed inside the storage space and connected to the pressurizing unit, and expands at least a portion of which via an additional electrical signal to adjust the lifting of the pressurizing unit.

[0008] However, existing body care devices can only perform simple lifting and lowering operations, with limited stretching directions. When the device is at its highest height, it may put strain on the user's neck.

[0009] Furthermore, in existing body care devices, the device stops when it is at its highest and lowest height, thus limiting the ability to perform soft, continuous work that provides a sensation similar to an actual massage.

[0010] As mentioned above, in the case of body care devices that perform massage through mechanical means, there are issues that need to be addressed in order to construct a more suitable structure, considering both effective massage and ease of use.

[0011] However, conventional body care devices have not been able to adequately address this issue. Utility Model Content

[0012] The purpose of this invention is to solve the aforementioned problems existing in body care devices that provide massage by physically stimulating the user's body.

[0013] Specifically, the purpose of this utility model is to provide a body care device that uses physical stimulation of the user's body structure to drive movements similar to those of a human hand, thereby further improving the massage effect.

[0014] In addition, the purpose of this invention is to provide a body care device that physically stimulates the user's body in a relatively simple structure, thereby making it easier to manufacture and maintain.

[0015] In addition, the purpose of this utility model is to provide a body care device that allows the structure in direct contact with the user's body to be elastically deformable, thereby enabling the best massage that reflects the user's characteristics.

[0016] The technical problems to be solved by this utility model are not limited to those mentioned above. Those skilled in the art can clearly understand other technical problems not mentioned herein from the following description.

[0017] To achieve the above or other objectives, in one side-mounted body care device of this invention, the massage part that physically stimulates the user's body is configured in a structure driven in a manner similar to the movement of a human hand. Specifically, the rotational force of the drive unit is transmitted to the massage part through an eccentric shaft, a first connecting rod, a rod, a second connecting rod, and a fixed shaft. When the drive unit is in operation, the massage part is not only driven in two dimensions, but is also driven without stopping when the height is at its highest or lowest point.

[0018] This utility model provides a side-mounted body care device, which includes:

[0019] Base section;

[0020] A drive unit that provides rotational force centered on a drive rotation axis, which is formed laterally along the base portion;

[0021] An eccentric shaft portion is arranged laterally along the base portion and has a length direction parallel to the drive rotation shaft, and rotates eccentrically when the drive portion is working.

[0022] The first link portion has one end connected to the eccentric shaft portion and extends in a direction intersecting the length direction of the eccentric shaft portion.

[0023] The rod portion, which is arranged laterally along the base portion and has a length direction parallel to the drive rotation axis, is connected to the other end of the first connecting rod portion.

[0024] The second link portion has one end connected to the aforementioned link portion and extends in a direction intersecting the length direction of the aforementioned link portion;

[0025] A fixed shaft portion, which is arranged laterally along the base portion and has a length direction parallel to the drive rotation shaft, restricts displacement other than shaft rotation, and is connected to the other end of the second linkage portion; and

[0026] The massage part is provided to protrude longitudinally along the base part and is attached to the rod part so as to be limited by the displacement of the rod part.

[0027] In addition, in one side of the body care device of this utility model, the auxiliary connecting rod connects the drive rotation shaft and the eccentric shaft.

[0028] In addition, in one side of the body care device of this utility model, the drive unit is connected to one end of the eccentric shaft, and the other end of the eccentric shaft is supported by a support plate.

[0029] In addition, in one side of the body care device of this utility model, multiple first connecting rods connect the eccentric shaft and the rod.

[0030] In addition, in one side of the body care device of this utility model, multiple second connecting rods connect the rod and the fixed shaft.

[0031] In addition, in one side of the body care device of this utility model, the rod is attached to the two sides of the massage part.

[0032] Furthermore, in one side-mounted body care device of this invention, the massage section that physically stimulates the user's body has a relatively simple structure. Specifically, it is configured such that a drive section is provided independently of the massage section, without a drive section.

[0033] In addition, one side of the body care device of this utility model is formed as a recessed shape on the upper surface of a part of the massage part.

[0034] Furthermore, in one side-mounted body care device of this invention, the upper surface of the massage part, which comes into direct contact with the user's body, is composed of a structure capable of elastic deformation. Specifically, an elastically deformable elastomer is disposed on the upper surface of the massage part.

[0035] In addition, in one side of the body care device of this utility model, the elastomer is composed of an airbag.

[0036] The means by which this utility model solves the technical problem are not limited to the solutions mentioned above. Those skilled in the art can clearly understand from the following description other solutions not mentioned herein.

[0037] The effects of this body care device are described below.

[0038] According to at least one embodiment of the present invention, the rotational force of the drive unit is transmitted to the massage unit through the eccentric shaft, the first connecting rod, the rod, the second connecting rod, and the fixed shaft. Thus, when the drive unit is working, the massage unit can not only be driven in two dimensions, but also be driven without stopping at the highest and lowest heights. Therefore, a drive similar to kneading by human hand is achieved, thereby further improving the massage effect.

[0039] In addition, according to at least one embodiment of the present invention, the auxiliary connecting rod connects the drive rotating shaft and the eccentric shaft, so that the rotational force of the drive part can be effectively converted into the eccentric rotation of the eccentric shaft.

[0040] In addition, according to at least one embodiment of the present invention, a drive unit is attached to one end of the eccentric shaft and the other end of the eccentric shaft is supported by a support plate. Therefore, even if the drive unit is biased towards one side of the eccentric shaft, the eccentric shaft can be rotated stably.

[0041] In addition, according to at least one embodiment of the present invention, a plurality of first connecting rods connect the eccentric shaft and the rod, thereby enabling stable transmission of driving force between the eccentric shaft and the rod.

[0042] Furthermore, according to at least one embodiment of the present invention, a plurality of second connecting rods connect the rod and the fixed shaft, thereby enabling stable transmission of driving force between the rod and the fixed shaft.

[0043] In addition, according to at least one embodiment of the present invention, the rod is attached to two sides of the massage part, thereby limiting unnecessary displacement of the massage part beyond two-dimensional drive.

[0044] Furthermore, according to at least one embodiment of the present invention, the drive unit is configured to be independently provided with the massage unit instead of the massage unit, thereby simplifying the structure of the massage unit and making it easier to manufacture and repair the massage unit.

[0045] In addition, according to at least one embodiment of the present invention, the massage part is formed with a portion of its upper surface recessed, so that the upper surface of the massage part can more effectively contact the user's neck.

[0046] In addition, according to at least one embodiment of the present invention, an elastically deformable elastomer is disposed on the upper surface of the massage part, thereby relieving some of the pressure that is inappropriately applied to the massage target area.

[0047] In addition, according to at least one embodiment of the present invention, the elastomer is composed of an air bladder, so the pressure applied to the massage target can be adjusted by adjusting the air pressure.

[0048] The scope of the invention will be clearly understood from the following detailed description. However, those skilled in the art will understand that various changes and modifications can be made to the invention within its spirit and scope; therefore, the detailed description and specific embodiments, such as preferred embodiments, are merely illustrative.

[0053] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. However, in describing the present invention, well-known functions or structures will be omitted in order to clearly understand the essence of the present invention.

[0054] In the embodiments of this utility model, the X, Y, and Z directions are mutually orthogonal. The X and Y directions are parallel to the horizontal direction, and the Z direction is parallel to the vertical direction. When the X direction is parallel to the left-right direction, the Y direction is parallel to the front-back direction. When the X direction is parallel to the front-back direction, the Y direction is parallel to the left-right direction.

[0055] Figure 1 This is a perspective view showing a body care device 1000 according to an embodiment of the present invention. Figure 2 It is shown illustratively in Figure 1The diagram shows the state in which the drive unit 200 is installed on the body care device 1000. Figure 3 This is a diagram showing the state in which the upper surface of the massage part 800 is removed in a body care device 1000 according to an embodiment of the present invention. Figures 4 to 6 This diagram illustratively illustrates the driving of various structures in a body care device 1000 according to an embodiment of the present invention via the operation of the drive unit 200.

[0056] One embodiment of the present invention, a body care device 1000, includes a base portion 100, a drive portion 200, an eccentric shaft portion 300, a first connecting rod portion 400, a rod portion 500, a second connecting rod portion 600, a fixed shaft portion 700, and a massage portion 800.

[0057] The base portion 100 is the main body of the body care device 1000 in this embodiment. The drive portion 200, eccentric shaft portion 300, first connecting rod portion 400, rod portion 500, second connecting rod portion 600, fixed shaft portion 700 and massage portion 800 are all driven by changing their position and configuration based on the base portion 100.

[0058] Such a base portion 100 can be part of a massage device such as a massage chair. In addition, the base portion 100 is formed independently to minimize relative movement.

[0059] Thus, the user can massage the area by driving the remaining components while bringing the area to be massaged close to the base 100.

[0060] The drive unit 200 provides a rotational force centered on the drive rotation shaft 201 formed laterally along the base portion 100, and generates a rotational force to cause the drive rotation shaft 201 to rotate.

[0061] Here, the drive unit 200 is composed of a drive motor and drive gears, etc.

[0062] The eccentric shaft portion 300 is a portion that is arranged laterally along the base portion 100 and has a length direction parallel to the drive rotation shaft 201, and rotates eccentrically when the drive portion 200 is working.

[0063] That is, when the drive rotation shaft 201 rotates, the eccentric shaft portion 300 arranged side by side with such drive rotation shaft 201 rotates along a circular path centered on drive rotation shaft 201.

[0064] The first link portion 400 is a portion having one end 401 connected to the eccentric shaft portion 300 and extending in a direction intersecting the length direction of the eccentric shaft portion 300.

[0065] That is, the driving force transmitted by the eccentric rotation of the eccentric shaft 300 is converted into a driving force in a direction that intersects the length direction of the eccentric shaft 300 by the first connecting rod 400.

[0066] The rod portion 500 is a portion that is arranged laterally along the base portion 100 and has a length direction parallel to the drive rotation shaft 201 and is connected to the other end 402 of the first connecting rod portion 400.

[0067] That is, while the rod 500 is parallel to the length direction of the drive rotation axis 201, it is driven by the drive path of the other end 402 of the first connecting rod 400.

[0068] The second link portion 600 is a portion having one end 601 connected to the link portion 500 and extending in a direction intersecting the length direction of the link portion 500.

[0069] That is, the driving force of the rod 500 is converted into a driving force in a direction that intersects the length direction of the rod 500 through the second link 600.

[0070] The fixed shaft portion 700 is a portion arranged laterally along the base portion 100, having a length direction parallel to the drive rotation shaft 201, and having displacement other than shaft rotation restricted, and connected to the other end 602 of the second link portion 600.

[0071] That is, as the displacement of the fixed shaft portion 700 on the base portion 100 other than rotation is restricted, the displacement of the other end 602 of the second link portion 600 connected to such fixed shaft portion 700 other than rotation is also restricted.

[0072] Therefore, the driving force transmitted by the operation of the drive unit 200 can change the position and configuration of the eccentric shaft 300, the first connecting rod 400, the rod 500 and the second connecting rod 600 between the drive rotation shaft 201 and the fixed shaft 700.

[0073] In particular, such as Figures 4 to 6 As shown, when the drive unit 200 is working, the rod 500 can undergo displacement in the Y direction and displacement in the Z direction. That is, the rod 500 can undergo two-dimensional displacement.

[0074] Furthermore, when the drive unit 200 is working, the drive rotation shaft 201 rotates continuously, so the rod 500 also undergoes continuous displacement without stopping at a specific position.

[0075] The massage unit 800 is a part that is provided protruding along the longitudinal direction of the base portion 100 and is attached to the rod portion 500 so as to be limited by the displacement of the rod portion 500. It is driven according to the drive of the rod portion 500 as described above, in a configuration corresponding to the rod portion 500.

[0076] That is, the massage unit 800 can be driven in two dimensions, rather than in one dimension, which is a drive that can only perform simple lifting and lowering movements. Furthermore, the massage unit 800 is continuously driven without stopping when it is at its highest and lowest height.

[0077] Thus, in the body care device 1000 of one embodiment of the present invention, the rotational force of the drive unit 200 is transmitted to the massage unit 800 through the eccentric shaft 300, the first connecting rod 400, the rod 500, the second connecting rod 600, and the fixed shaft 700. When the drive unit 200 is working, the massage unit 800 can not only be driven in two dimensions, but also be driven without stopping when the height is at its highest and lowest. Therefore, a drive similar to kneading performed by a human hand is achieved, thereby further improving the massage effect.

[0078] One embodiment of the body care device 1000 of this utility model further includes: an auxiliary connecting rod 900, one end 901 of which is connected to the aforementioned drive rotating shaft 201, and the other end 902 of which is connected to the eccentric shaft 300.

[0079] That is, the auxiliary connecting rod portion 900 extends in a direction that intersects the length direction of the eccentric shaft portion 300, thereby enabling the connection between the drive rotation shaft 201 and the eccentric shaft portion 300.

[0080] Therefore, the rotational force of the drive shaft 201 is transmitted to the eccentric shaft 300 through the auxiliary connecting rod 900, thereby enabling the eccentric rotation of the eccentric shaft 300 to be smoothly achieved.

[0081] Thus, in a body care device 1000 of one embodiment of the present invention, the auxiliary connecting rod 900 connects the drive rotation shaft 201 and the eccentric shaft 300, thereby effectively converting the rotational force of the drive 200 into the eccentric rotation of the eccentric shaft 300.

[0082] In one embodiment of the body care device 1000 of this utility model, the drive unit 200 is coupled to one end 301 of the eccentric shaft portion 300 to provide rotational force. In this case, the base portion 100 includes a support plate 110 that supports the other end 302 of the eccentric shaft portion 300 and restricts displacement of the eccentric shaft portion 300 other than eccentric rotation.

[0083] That is, the drive unit 200 is attached to one end 301 of the eccentric shaft 300 and is positioned biased towards one side of the eccentric shaft 300. In this case, the drive unit 200 can be configured relatively freely, but it may be difficult to transmit the driving force evenly along the entire length of the eccentric shaft 300.

[0084] Therefore, by supporting the other end 302 of the eccentric shaft portion 300 by the support plate 110 provided on the base portion 100, unnecessary displacement of the eccentric shaft portion 300 portion not connected to the drive portion 200 is limited, while the eccentric shaft portion 300 is driven stably as a whole.

[0085] Thus, in a body care device 1000 of one embodiment of the present invention, the drive unit 200 is connected to one end 301 of the eccentric shaft 300 and the other end 302 of the eccentric shaft 300 is supported by the support plate 110. Therefore, even if the drive unit 200 is biased to one side of the eccentric shaft 300, the eccentric shaft 300 can be rotated stably.

[0086] In one embodiment of the body care device 1000 of the present invention, the first connecting rod portion 400 is connected to the eccentric shaft portion 300 and the rod portion 500 at multiple locations.

[0087] That is, multiple first link portions 400 are formed, and each first link portion 400 is connected to the eccentric shaft portion 300 and the rod portion 500. In this case, each first link portion 400 can also be connected to each other to form a single unit.

[0088] Both the eccentric shaft portion 300 and the rod portion 500 are shaped to extend along the length direction. Considering this, if the first connecting rod portion 400 is connected at only one position, an unbalanced state may occur around that position.

[0089] Therefore, the first link 400 connects the eccentric shaft 300 and the rod 500 at multiple locations, thereby preventing the aforementioned imbalance.

[0090] Thus, in a body care device 1000 of one embodiment of the present invention, a plurality of first connecting rods 400 connect the eccentric shaft 300 and the rod 500, thereby enabling stable transmission of driving force between the eccentric shaft 300 and the rod 500.

[0091] In one embodiment of the body care device 1000 of this utility model, the second connecting rod portion 600 connects the rod portion 500 and the fixed shaft portion 700 at multiple locations.

[0092] That is, multiple second link portions 600 are formed, and each second link portion 600 connects the link portion 500 and the fixed shaft portion 700. In this case, the individual second link portions 600 are connected to each other and can be formed as a single unit.

[0093] Both the rod portion 500 and the fixed shaft portion 700 are shaped to extend along the length direction. Considering this, if the second link portion 600 is connected at only one position, an unbalanced state may occur around that position.

[0094] Therefore, the second link 600 connects the link 500 and the fixed shaft 700 at multiple locations, thereby preventing the aforementioned imbalance.

[0095] Thus, in a body care device 1000 of one embodiment of the present invention, a plurality of second connecting rods 600 connect the rod 500 and the fixed shaft 700, thereby enabling stable transmission of driving force between the rod 500 and the fixed shaft 700.

[0096] In one embodiment of the body care device 1000 of this utility model, the rod portion 500 is attached to two sides of the massage portion 800. That is, the two ends of the rod portion 500 are respectively attached to the two sides of the massage portion 800.

[0097] The massage part 800 can also be formed in a shape that extends laterally along the base part 100, and the two sides of the massage part 800 are respectively connected to the two ends of the rod part 500 to maintain a stable connection.

[0098] In particular, as described above, when the drive unit 200 is working, the massage unit 800 is driven in two dimensions to improve the massage effect. From this point of view, it is preferable to limit unnecessary displacements beyond such two-dimensional drive.

[0099] Thus, in a body care device 1000 of one embodiment of the present invention, rods 500 are attached to both sides of the massage part 800, thereby limiting unnecessary displacement of the massage part 800 beyond two-dimensional drive.

[0100] In one embodiment of the present invention, the body care device 1000 has a drive unit 200 disposed outside the massage unit 800.

[0101] That is, the drive unit 200 is located in a separate space outside the massage unit, rather than inside the massage unit 800, and the driving force of such a drive unit 200 is transmitted to the drive rotation shaft 201 through drive gears or the like.

[0102] Therefore, other structures besides the drive unit 200 can be freely configured in the internal space of the massage unit 800, and the operation can be carried out smoothly when repairing the drive unit 200 without disassembling the massage unit 800.

[0103] Thus, in one embodiment of the present invention, the body care device 1000 is configured such that the drive unit 200 is not provided in the massage unit 800, but is provided independently of the massage unit 800. Therefore, the structure of the massage unit 800 can be simplified, thereby making it easier to manufacture and maintain the massage unit 800.

[0104] In one embodiment of the body care device 1000 of the present invention, a portion of the upper surface of the massage part 800 is recessed.

[0105] The two-dimensional drive of the massage unit 800 described above is more suitable for massaging the neck of the user's body. That is, the user activates the drive unit 200 to perform a massage while the neck is in contact with the upper surface of the massage unit 800.

[0106] In this case, it is preferable that a portion of the upper surface of the massage part 800 is recessed in accordance with the curved shape of the neck, thereby maximizing the contact area between the upper surface of the massage part 800 and the user's neck.

[0107] Thus, in one embodiment of the present invention, the body care device 1000 is formed with a recessed shape on part of the upper surface of the massage part 800, so that the upper surface of the massage part 800 can make more effective contact with the user's neck.

[0108] In a body care device 1000 according to one embodiment of the present invention, an elastic body 810 capable of elastic deformation is provided on the upper surface of the massage part 800.

[0109] When the massage unit 800 comes into contact with the user's massage target area to perform a massage, the user may experience pain due to issues such as pressure being concentrated in a specific area.

[0110] Therefore, it is preferable to provide an elastomer 810 on the upper surface of the massage part 800 to appropriately disperse pressure when pressure is concentrated in a specific area.

[0111] Thus, in one embodiment of the body care device 1000 of this utility model, an elastic body 810 capable of elastic deformation is disposed on the upper surface of the massage part 800, thereby buffering a portion of the pressure inappropriately applied to the massage target area.

[0112] In one embodiment of the body care device 1000 of this utility model, the elastomer 810 is composed of an airbag 811 that can adjust the degree of air injection.

[0113] When the massage unit 800 comes into contact with the user's massage target area to perform a massage, some users may feel that the applied pressure is too high, while others may feel that the applied pressure is too low.

[0114] Thus, even when performing a massage with the same pressure, the user's perception of the pressure intensity will vary depending on their characteristics. From this perspective, it is preferable to use the massage unit 800 by having each user adjust the air injection level of the airbag 811 located on the upper surface of the massage unit 800.

[0115] Thus, in one embodiment of the body care device 1000 of this utility model, the elastomer 810 is composed of an airbag 811, so the pressure applied to the massage target can be adjusted by adjusting the air pressure.

[0116] The above description and illustrations illustrate specific embodiments of the present invention. However, the present invention is not limited to the embodiments described herein. Those skilled in the art will understand that various modifications and variations can be made to the present invention without departing from its spirit and scope. Therefore, such modifications or variations should not be understood independently of the technical concept or viewpoint of the present invention, and the modified embodiments should fall within the scope of the present invention.
