Description

Body care devices

[0001] The present invention relates to a body care device, and more particularly, to a body care device that can provide a massage by physically stimulating a user's body.

[0002] With the recent aging of society, awareness of health management, health maintenance, and health promotion is increasing across all age groups. Consequently, many people are utilizing facilities such as medical facilities or sports clubs to manage, maintain, or improve their health.

[0003] Additionally, many people are striving to recover from fatigue and relieve stress, just as they are striving to maintain or improve their health and fitness. To this end, various body care devices, such as massagers, have been developed and are widely used in everyday life.

[0004] Massage is a medical auxiliary therapy that promotes blood circulation and relieves fatigue by using hands or special tools to stroke, knead, press, pull, tap, or move the body. Massage equipment is a mechanical device that performs massage, and various mechanical elements are incorporated into massage equipment to ensure effective results.

[0005] In relation to a body care device that performs massage using the mechanical device described above, Korean Patent Publication No. 10-2023-0061714 (hereinafter referred to as “prior document”) discloses a occipital massage device.

[0006] Specifically, the present invention discloses a housing in which the user's back of the head is supported by being seated on at least a portion of the upper surface, a pressurizing unit that raises and lowers at least a portion of the housing and pressurizes the user's back of the head with a preset pressure or pattern, and a lifting and lowering control unit that is provided inside the receiving space and is connected to the pressing unit and expands at least a portion of the housing through a separate electrical signal and controls the lifting and lowering of the pressing unit.

[0007] However, the body care device of the prior literature has a problem in that it only allows simple up-and-down movements, so the stretching direction is limited and it may put a strain on the user's neck when the device is at its highest height.

[0008] In addition, the body care device of the prior literature has a limitation in that it is impossible to provide smooth continuous motion that gives the feeling of an actual massage because the device stops when the height of the device is at its maximum and minimum.

[0009] As described above, a body care device that performs massage by a mechanical device has a problem that must be solved in order to have a more appropriate structure in terms of effective massage and convenience of use.

[0010] However, conventional body care devices have limitations in that they cannot adequately solve these problems.

[0011] The present invention aims to solve the above problems of a body care device that provides massage by physically stimulating a user's body.

[0012] Specifically, the present invention aims to provide a body care device that can further enhance the massage effect by making the configuration that physically stimulates the user's body actuated in a manner similar to the movement of a human hand.

[0013] In addition, the present invention aims to provide a body care device having a relatively simple structure for physically stimulating a user's body, thereby making it easier to manufacture and maintain.

[0014] In addition, the present invention aims to provide a body care device that enables an optimal massage reflecting the characteristics of the user by enabling a component that comes into direct contact with the user's body to be elastically deformable.

[0015]

[0016] The technical problems to be achieved in the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0017] In order to achieve the above or other purposes, a body care device according to one aspect of the present invention is configured such that a massage unit for physically stimulating a user's body is structured to be driven similarly to the movement of a human hand. Specifically, the rotational force of the driving unit is transmitted to the massage unit through an eccentric shaft unit, a first link unit, a rod unit, a second link unit, and a fixed shaft unit, so that when the driving unit is operated, the massage unit is driven two-dimensionally and is driven without stopping when the height is maximum or minimum.

[0018] In addition, a body care device according to one aspect of the present invention may have an auxiliary link portion that connects a driving rotation shaft and an eccentric shaft portion.

[0019] In addition, a body care device according to one aspect of the present invention may have a driving unit coupled to one end of an eccentric shaft, and a support plate supporting the other end of the eccentric shaft.

[0020] In addition, a body care device according to one aspect of the present invention may connect an eccentric shaft portion and a load portion with a plurality of first link portions.

[0021] In addition, a body care device according to one aspect of the present invention can connect a load portion and a fixed shaft portion with a plurality of second link portions.

[0022] In addition, a body care device according to one aspect of the present invention may have a load unit coupled to both sides of a massage unit.

[0023] In addition, a body care device according to one aspect of the present invention is configured such that the massage unit, which physically stimulates the user's body, has a relatively simple structure. Specifically, the massage unit is configured such that the drive unit is installed separately from the massage unit, without a drive unit being installed therein.

[0024] In addition, a body care device according to one aspect of the present invention may have a shape in which the upper surface of the massage part is partially sunken.

[0025] In addition, a body care device according to one aspect of the present invention is configured such that the upper surface of the massage unit, which comes into direct contact with the user's body, is formed of an elastically deformable structure. Specifically, an elastically deformable elastic body is configured to be installed on the upper surface of the massage unit.

[0026] Additionally, a body care device according to one aspect of the present invention may have an elastic body formed as an airbag.

[0027]

[0028] The means for solving the technical problems to be solved by the present invention are not limited to the means for solving the problems mentioned above, and other means for solving the problems not mentioned will be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0035]

[0036] Fig. 1 is a perspective view showing a body care device (1000) according to one embodiment of the present invention. Fig. 2 is a drawing showing a state in which a driving unit (200) is installed in the body care device (1000) shown in Fig. 1. Fig. 3 is a drawing showing a state in which the upper surface of a massage unit (800) is removed in the body care device (1000) according to one embodiment of the present invention. Figs. 4 to 6 are drawings showing the driving of each component according to the operation of the driving unit (200) in the body care device (1000) according to one embodiment of the present invention.

[0037] A body care device (1000) according to one embodiment of the present invention includes a base portion (100), a driving portion (200), an eccentric shaft portion (300), a first link portion (400), a load portion (500), a second link portion (600), a fixed shaft portion (700), and a massage portion (800).

[0038] The base part (100) is a part that forms the main body of the body care device (1000) according to the present embodiment, and the driving part (200), the eccentric shaft part (300), the first link part (400), the load part (500), the second link part (600), the fixed shaft part (700), and the massage part (800) can all be driven while changing their positions and arrangements based on the base part (100).

[0039] This base part (100) may be a part of a massage device such as a massage chair. In addition, the base part (100) may be formed independently and may be a part in which relative movement is minimized.

[0040] Accordingly, the user can massage the area to be massaged by operating the remaining components while bringing the area to be massaged close to the base (100).

[0041] The driving unit (200) is a unit that provides rotational force centered on the driving rotation shaft (201) along the transverse direction of the base unit (100), and can generate rotational force to rotate the driving rotation shaft (201) about its axis.

[0042] Here, the driving unit (200) may include a driving motor and a driving gear, etc.

[0043] The eccentric shaft portion (300) is arranged to have a longitudinal direction parallel to the driving rotation shaft (201) along the transverse direction of the base portion (100) and is a portion that rotates eccentrically when the driving portion (200) is operated.

[0044] That is, when the drive rotation shaft (201) rotates, the eccentric shaft (300) arranged parallel to the drive rotation shaft (201) can rotate along a circular path centered on the drive rotation shaft (201).

[0045] The first link portion (400) is a portion formed such that one end (401) is connected to the eccentric shaft portion (300) and extends in a direction intersecting the longitudinal direction of the eccentric shaft portion (300).

[0046] That is, the driving force transmitted by the eccentric rotation of the eccentric shaft portion (300) can be converted into a driving force in a direction intersecting the longitudinal direction of the eccentric shaft portion (300) by the first link portion (400).

[0047] The load section (500) is arranged to have a longitudinal direction parallel to the driving rotation axis (201) along the transverse direction of the base section (100) and is a section connected to the other end (402) of the first link section (400).

[0048] That is, the load section (500) can be driven by being constrained to the driving path of the other end (402) of the first link section (400) while maintaining a longitudinal direction parallel to the driving rotation shaft (201).

[0049] The second link portion (600) is a portion formed such that one end (601) is connected to the load portion (500) and extends in a direction intersecting the length direction of the load portion (500).

[0050] That is, the driving force of the load section (500) can be converted into a driving force in a direction intersecting the longitudinal direction of the load section (500) by the second link section (600).

[0051] The fixed shaft portion (700) is arranged to have a longitudinal direction parallel to the driving rotation shaft (201) along the transverse direction of the base portion (100), so that displacement other than the axis rotation is limited and is a portion connected to the other end (602) of the second link portion (600).

[0052] That is, as the fixed shaft part (700) is restricted from displacement other than axial rotation in the base part (100), the other end (602) of the second link part (600) connected to the fixed shaft part (700) can also be restricted from displacement other than rotation.

[0053] Accordingly, the driving force transmitted by the operation of the driving unit (200) can change the position and arrangement of each of the eccentric shaft unit (300), the first link unit (400), the load unit (500), and the second link unit (600) between the driving rotation shaft (201) and the fixed shaft unit (700).

[0054] In particular, as illustrated in FIGS. 4 to 6, when the driving unit (200) is operated, the load unit (500) may experience displacement in the Z direction as well as displacement in the Y direction. That is, the load unit (500) may experience two-dimensional displacement.

[0055] In addition, since the drive rotation shaft (201) rotates continuously when the drive unit (200) is in operation, the load unit (500) can also continuously move without stopping at a specific position.

[0056] The massage part (800) is installed to protrude along the longitudinal direction of the base part (100) and is a part that is coupled to the load part (500) so as to be restricted from displacement of the load part (500). Depending on the operation of the load part (500) as described above, the massage part (800) can be driven in a configuration corresponding to the load part (500).

[0057] That is, the massage unit (800) can be driven two-dimensionally, rather than one-dimensionally, allowing only simple up-and-down movements. In addition, the massage unit (800) can be driven continuously without stopping when the height is at its maximum or minimum.

[0058] In this way, the body care device (1000) according to one embodiment of the present invention transmits the rotational force of the driving unit (200) to the massage unit (800) through the eccentric shaft unit (300), the first link unit (400), the load unit (500), the second link unit (600), and the fixed shaft unit (700), so that when the driving unit (200) operates, the massage unit (800) is driven two-dimensionally and is driven without stopping when the height is at its maximum and minimum, so that driving similar to kneading by a human hand is implemented, and the massage effect can be further improved.

[0059] A body care device (1000) according to one embodiment of the present invention may further include an auxiliary link part (900) having one end (901) connected to the driving rotation shaft (201) and the other end (902) connected to the eccentric shaft part (300).

[0060] That is, the auxiliary link portion (900) is formed to extend in a direction intersecting the longitudinal direction of the eccentric shaft portion (300) so as to connect the driving rotation shaft (201) and the eccentric shaft portion (300).

[0061] Accordingly, the axial rotational force of the driving rotation shaft (201) is transmitted to the eccentric shaft (300) through the auxiliary link (900), so that the eccentric rotation of the eccentric shaft (300) can be smoothly achieved.

[0062] In this way, in the body care device (1000) according to one embodiment of the present invention, since the auxiliary link (900) connects the driving rotation shaft (201) and the eccentric shaft (300), the rotational force of the driving unit (200) can be effectively converted into eccentric rotation of the eccentric shaft (300).

[0063] In a body care device (1000) according to one embodiment of the present invention, a driving unit (200) may be coupled to one end (301) of an eccentric shaft unit (300) to provide rotational force. In this case, the base unit (100) may include a support plate (110) that supports the other end (302) of the eccentric shaft unit (300) to limit displacement of the eccentric shaft unit (300) other than eccentric rotation.

[0064] That is, the driving unit (200) may be coupled to one end (301) of the eccentric shaft unit (300) and may be arranged biasedly on one side of the eccentric shaft unit (300). In this case, the arrangement of the driving unit (200) may be relatively free, but there is a concern that the driving force may not be evenly transmitted along the entire length of the eccentric shaft unit (300).

[0065] Accordingly, by supporting the other end (302) of the eccentric shaft portion (300) through the support plate (110) installed on the base portion (100), unnecessary displacement of the portion of the eccentric shaft portion (300) to which the driving portion (200) is not coupled can be limited, while the eccentric shaft portion (300) can be driven stably as a whole.

[0066] In this way, the body care device (1000) according to one embodiment of the present invention has a driving unit (200) coupled to one end (301) of an eccentric shaft unit (300), and a support plate (110) supports the other end (302) of the eccentric shaft unit (300), so that even if the driving unit (200) is arranged to be biased toward one side of the eccentric shaft unit (300), the eccentric shaft unit (300) can be stably rotated.

[0067] In a body care device (1000) according to one embodiment of the present invention, the first link portion (400) can connect the eccentric shaft portion (300) and the load portion (500) at multiple points.

[0068] That is, the first link portion (400) is formed in multiple pieces, and each first link portion (400) can connect the eccentric shaft portion (300) and the load portion (500). In this case, each first link portion (400) may be connected to each other and formed as one piece.

[0069] Since both the eccentric shaft portion (300) and the load portion (500) are formed in a shape extending along the longitudinal direction, there is a concern that if the first link portion (400) is connected at only one point, an imbalance may occur around that point.

[0070] Accordingly, the eccentric shaft portion (300) and the load portion (500) can be connected by the first link portion (400) at multiple points to prevent the occurrence of an imbalance such as the above.

[0071] In this way, the body care device (1000) according to one embodiment of the present invention connects the eccentric shaft portion (300) and the load portion (500) with a plurality of first link portions (400), so that the driving force between the eccentric shaft portion (300) and the load portion (500) can be stably transmitted.

[0072] In a body care device (1000) according to one embodiment of the present invention, the second link portion (600) can connect the load portion (500) and the fixed shaft portion (700) at multiple points.

[0073] That is, the second link portion (600) is formed in multiple pieces, and each second link portion (600) can connect the load portion (500) and the fixed shaft portion (700). In this case, each second link portion (600) may be connected to each other and formed as one piece.

[0074] Since both the load section (500) and the fixed shaft section (700) are formed in a shape extending along the longitudinal direction, there is a concern that if the second link section (600) is connected at only one point, an imbalance may occur around that point.

[0075] Accordingly, the load section (500) and the fixed shaft section (700) can be connected by the second link section (600) at multiple points to prevent the occurrence of an imbalance such as the above.

[0076] In this way, the body care device (1000) according to one embodiment of the present invention connects the load portion (500) and the fixed shaft portion (700) with a plurality of second link portions (600), so that the driving force between the load portion (500) and the fixed shaft portion (700) can be stably transmitted.

[0077] In a body care device (1000) according to one embodiment of the present invention, the load portion (500) can be coupled to both sides of the massage portion (800). That is, both sides of the massage portion (800) can be coupled to each end of the load portion (500).

[0078] The massage part (800) may also be formed in a shape that extends along the transverse direction of the base part (100) to a certain extent, and it is necessary to maintain a stable bonding state by connecting both ends of the load part (500) to each of the two sides of the massage part (800).

[0079] In particular, as described above, since the massage unit (800) performs two-dimensional driving when the driving unit (200) is operated, thereby improving the massage effect, it may be desirable to limit unnecessary displacement other than this two-dimensional driving.

[0080] In this way, since the body care device (1000) according to one embodiment of the present invention has the load portion (500) coupled to both sides of the massage portion (800), unnecessary displacement other than the two-dimensional driving of the massage portion (800) can be limited.

[0081] In a body care device (1000) according to one embodiment of the present invention, the driving unit (200) may be installed outside the massage unit (800).

[0082] That is, the driving unit (200) is not installed within the massage unit (800), but is installed in a separate space outside the massage unit, and the driving force of the driving unit (200) can be transmitted to the driving rotation shaft (201) through a driving gear or the like.

[0083] Accordingly, it is possible to freely place other components other than the driving unit (200) in the internal space of the massage unit (800), and maintenance of the driving unit (200) can be performed smoothly without disassembling the massage unit (800).

[0084] In this way, the body care device (1000) according to one embodiment of the present invention is structured so that the driving unit (200) is not installed in the massage unit (800) but is installed separately from the massage unit (800), so that the structure of the massage unit (800) can be further simplified, and the manufacturing and maintenance of the massage unit (800) can be easily achieved.

[0085] In a body care device (1000) according to one embodiment of the present invention, a portion of the upper surface of the massage unit (800) may be formed to be sunken.

[0086] The two-dimensional driving of the massage unit (800) as described above may be more appropriate for massaging the neck area of ​​the user's body. That is, the user may operate the driving unit (200) while keeping the neck area in contact with the upper surface of the massage unit (800) to provide a massage.

[0087] In this case, it may be desirable to form a portion of the upper surface of the massage part (800) to be sunken to correspond to the curved shape of the neck area, thereby maximizing the contact area between the upper surface of the massage part (800) and the user's neck area.

[0088] In this way, the body care device (1000) according to one embodiment of the present invention has a shape in which the upper surface of the massage part (800) is partially sunken, so that the upper surface of the massage part (800) can more effectively come into contact with the user's neck area.

[0089] In a body care device (1000) according to one embodiment of the present invention, an elastic body (810) that can be elastically deformed may be installed on the upper surface of the massage unit (800).

[0090] When the massage part (800) comes into contact with the user's massage target area and a massage is performed, there is a concern that pain may be caused to the user due to problems such as pressure being concentrated on a specific area.

[0091] Therefore, it may be desirable to install an elastic body (810) on the upper surface of the massage part (800) to appropriately distribute the pressure when pressure is concentrated on a specific part.

[0092] In this way, the body care device (1000) according to one embodiment of the present invention can partially buffer pressure inappropriately applied to the massage target area since the elastically deformable elastic body (810) is installed on the upper surface of the massage part (800).

[0093] In a body care device (1000) according to one embodiment of the present invention, the elastic body (810) may be formed as an air bag (811) capable of controlling the degree of air injection.

[0094] When a massage is performed by contacting the massage part (800) on the user's massage target area, some users may feel that the pressure applied is too strong, and other users may feel that the pressure applied is too weak.

[0095] In this way, even when a massage is performed with the same pressure, the feeling of pressure intensity may differ depending on the characteristics of each user, so it may be desirable to have each user adjust the amount of air injected into the air bag (811) installed on the upper surface of the massage unit (800).

[0096] In this way, the body care device (1000) according to one embodiment of the present invention can control the pressure applied to the massage target area by controlling the air pressure since the elastic body (810) is formed of an air bag (811).

[0097]
