Abstract

The present invention relates to a massage device, as one embodiment of the present invention, comprising: a first frame comprising a massage module; a second frame coupled to the first frame so as to be movable with respect to the first frame; a drive unit located in the first frame and providing a drive force to the second frame; and a link unit located between the second frame and the drive unit and configured to move the second frame based on a driving force of the drive unit.

Description

Technical Field

[0001] The present invention relates to a massage device including an expandable support portion, and more particularly, to a massage device including an expandable support portion, wherein when a first frame and a second frame overlap each other, the second frame rotates and expands with the first frame as a reference. Background Art

[0002] Massage or Tuina refers to a medical auxiliary therapy that applies various forms of mechanical stimulation to parts of the body by kneading, acupressure, stretching, tapping or moving the body, thereby adjusting the body changes of the massage recipient, promoting blood circulation and relieving fatigue of the massage recipient.

[0003] As the demand for massage increases, the need for deployable massage devices or equipment that provide manual massage functions has also grown for both economic and time-sensitive reasons. Specifically, as the need for massage to relieve muscle tension, fatigue, and stress grows, various deployable massage devices that offer both time- and cost-effective solutions have been introduced. Any tool, device, or apparatus that mechanically massages without a masseur is considered a deployable massage device.

[0004] In recent years, expandable massage devices have also been manufactured into bed-type devices, which allow users to receive massages while lying down. Such bed-type expandable massage devices provide massages by moving the massage module and stimulating the waist and back of the lying user.

[0005] On the other hand, existing expandable bed-type massagers have the disadvantage of being bulky because they require a length at least equal to the user's height. While conventional expandable massagers address this issue by providing a manually foldable structure corresponding to the leg section, this still presents the inconvenience of having to manually adjust the leg section each time a massage is performed.

[0006] In addition, the massage module that directly provides massage moves in direct or indirect contact with the user's body, and thus may get stuck in the user's body during movement. If the massage module is forcibly moved in this case, it may cause damage to the user's body.

[0007] Therefore, there is a need to develop an expandable massage device that can reduce the volume, provide massage to the user safely, and further provide massage to the user more effectively. Summary of the Invention

[0077] Figure 1 FIG. 1 is a diagram showing an example of use of the deployable massage device 100 according to an embodiment of the present invention. Figure 2 Is used to illustrate Figure 1 1 is a diagram illustrating an example of driving the deployable massage device 100.

[0078] refer to Figure 1 and Figure 2 , the expandable massage device 100 according to an embodiment of the present invention may include a first frame 110 and a massage module 200 .

[0079] The first frame 110 may constitute the overall appearance of the deployable massage device 100. The massage module 200 may be configured in the deployable massage device 100 to provide massage to the user's body.

[0080] The first frame 110 may be box-shaped as a whole, for example, in the shape of furniture such as a bed or a sofa.

[0081] The first frame 110 may include an upper surface on which the user can lie and support the user's upper body (eg, from the user's head to the buttocks). For example, the user may lie on the upper surface of the first frame 110 with his back against it to receive a massage.

[0082] The first frame 110 may have a space inside. For example, the first frame 110 may be in the shape of a bed from the outside, and may have a space inside. To this end, the first frame 110 may be configured with a frame portion 112 (see FIG. 1 ) that constitutes the overall shape of the first frame 110. Figure 6 ), and at least one plate can be configured with the frame portion 112 as a reference to form the first frame 110.

[0083] The end of the first frame 110 away from the second frame 120 may include a bent portion 400 (see FIG. Figure 7 The bending portion 400 may be located at the other end of the first frame 110 , and the end of the support portion of the first frame 110 may have a curvature in the height direction so as to have a predetermined angle in the height direction of the first frame 110 , or may protrude from the upper end of the first frame 110 at a predetermined angle.

[0084] The bending portion 400 may include any shape with the first frame 110 as a reference and the distal end thereof protruding at a predetermined angle, so that the massage module 200 can smoothly massage the neck of the user.

[0085] The massage module 200 may be disposed inside a cushion covering the upper surface of the first frame 110. For example, the massage module 200 may be disposed in a space provided inside the cushion of the first frame 110.

[0086] The massage module 200 may move in at least one of a length direction of the first frame 110 and a height direction of the first frame 110 and massage at least a portion of a user's body.

[0087] The massage module 200 can directly or indirectly contact the user's body and provide massage for the user. In addition, the massage module 200 can provide massage by pressing the user's body or applying vibration to the user's body.

[0088] For example, the massage module 200 may move in contact with the user's body and press the user's body to provide acupressure massage.

[0089] Alternatively, the massage module 200 may include a vibration motor to provide a vibration massage to the user's body. Alternatively, the massage module 200 may move up and down at a predetermined position to provide a percussion massage.

[0090] However, the massage modes provided by the massage module 200 are not limited thereto.

[0091] The upper surface of the first frame 110 may be formed with a massage groove such that at least a portion of the massage module 200 is exposed.

[0092] As an embodiment, the massage groove may be formed along the length direction of the first frame 110 in the height direction of the user.

[0093] The massage module 200 may be disposed inside the first frame 110 , and at least a portion thereof may be exposed to the outside via a massage groove formed on an upper surface thereof.

[0094] At least a portion of the massage module 200 may be exposed to the outside through the massage groove and directly or indirectly contact the user's body to provide massage.

[0095] Here, the massage module 200 directly contacts the user's body and provides massage, which means that the deployable massage device 100 does not include a separate member covering the massage groove, so that the massage module 200 provides massage in a state of directly contacting the user's body.

[0096] Furthermore, the fact that the massage module 200 indirectly contacts the user's body and provides massage means that the deployable massage device 100 includes a separate member covering the massage groove. Specifically, this means that a separate member covering the massage groove is positioned between the massage module 200 and the user's body. Thus, the massage module 200 can press or vibrate the additional member covering the massage groove, and this pressure or vibration can be transmitted to the user's body. In this case, the separate member covering the massage groove can be made of, but is not limited to, fabric, leather, synthetic resin, or synthetic leather.

[0097] The massage module 200 can move along the length of the massage groove within the first frame 110. For example, the massage module 200 can move along the massage groove while massaging the user's body. In this case, the massage module 200 can move along the curved portion 400, massaging the user's neck while in close proximity.

[0098] Therefore, the massage module 200 can provide massage for multiple parts of the user's body. Specifically, the massage module 200 can move from near the user's neck to the user's waist and provide massage for the user's body.

[0099] As an embodiment, the deployable massage device 100 may include a second frame 120 disposed on one side of the first frame 110 and supporting the user's lower body (eg, at least a portion of the user's legs).

[0100] The second frame 120 may support the leg portion that is not supported by the first frame 110 in a state in which the user lies on the upper surface of the first frame 110 .

[0101] The second frame 120 may at least partially overlap with the first frame 110 and maintain a retracted state. When a driving force of the driving unit is applied, the second frame 120 may move along the length direction of the first frame 110 and expand.

[0102] In other words, the second frame 120 can be a covering portion whose lower portion overlaps with the upper surface of the first frame 110 to protect (or cover) the upper surface of the first frame 110, or it can be a supporting portion that is arranged on one side of the first frame 110 and extended along the length direction of the first frame 110 to support the lower body of the user.

[0103] The expandable massage device 100 according to the present invention may further include a control unit. The control unit can control the operation of the expandable massage device 100. The control unit can be implemented by a single processor or multiple processors. When the control unit is implemented by multiple processors, at least some of the multiple processors can be located at physically separated locations. Furthermore, the control unit is not limited to this and can be implemented in various ways.

[0104] For example, the control unit may correspond to one or more processors. A processor may be implemented by a plurality of logic gate arrays, or may be implemented by a combination of a general-purpose microprocessor and a memory storing a program executable by the microprocessor. Furthermore, those skilled in the art will appreciate that other forms of hardware may also be used for implementation.

[0105] According to one embodiment, the control unit can control the movement of the deployable massage device 100. For example, the control unit can control the deployment of the second frame 120. Furthermore, the control unit can control the movement of the massage module 200. Specifically, the control unit can control the movement of the massage module 200 along the user's height and adjust the height of the massage module 200. Furthermore, the control unit can control the intensity and heating temperature of the massage provided to the user by the massage module 200.

[0106] In addition, the deployable massage device 100 may include a plurality of actuators, and the control unit may control the movement of the deployable massage device 100 by controlling the operations of the plurality of actuators.

[0107] Figure 3 FIG. 2 is a diagram showing a massage module 200 according to an embodiment of the present invention. Figure 4 yes Figure 3 Schematic exploded perspective view of .

[0108] Reference Figure 3 and Figure 4 According to an embodiment of the present invention, a massage module 200 may include at least one of a massage portion 210, a tilting portion 220, a height adjustment portion 230, and a moving portion 240. The massage portion 210 may be a device for massaging the user's body. For example, the massage portion 210 may provide vibration massage, acupressure massage, percussion massage, etc. to the user's body.

[0109] The tilting portion 220 may be a device disposed at one side of the massage portion 210 and used to connect the massage portion 210 and the height adjustment portion 230 .

[0110] The height adjustment portion 230 may be a device connected to the tilting portion 220 and used to adjust the height of the massage portion 210 .

[0111] For example, the height adjustment portion 230 may be connected to the inclined portion 220, and the inclined portion 220 may be connected to the massage portion 210. Therefore, the height adjustment portion 230 may simultaneously adjust the height of the massage portion 210 by adjusting the height of the inclined portion 220.

[0112] In this way, the height of the massage part 210 can be adjusted according to the user's body and provide massage to the user's body.

[0113] Furthermore, the height of the massage portion 210 may be adjusted according to the intensity of the massage to be provided, thereby providing massages of different intensities to the user's body.

[0114] The movable portion 240 may be a device for moving the massage module 200. For example, the movable portion 240 may include a space for accommodating the height adjustment portion 230. In this case, the height adjustment portion 230 may be connected to the inclined portion 220, which in turn may be connected to the massage portion 210. Thus, the movable portion 240 can move the massage portion 210, the inclined portion 220, and the height adjustment portion 230 by moving the accommodated height adjustment portion 230. In other words, the movable portion 240 can move the entire massage module 200.

[0115] Figure 5 It shows Figure 4 FIG. 210 of the massage part.

[0116] Referring to the drawings, the massage part 210 may include at least one of a module base 211 , massage balls 212 , side covers 213 , and a top cover 214 .

[0117] The module base 211 may constitute the entire framework of the massage portion 210. The module base 211 may include a space for accommodating massage balls 212. As described below, the massage portion 210 may include at least one massage ball 212, and the module base 211 may include a space for accommodating massage balls corresponding to the number of massage balls 212 provided.

[0118] The side covers 213 may be provided on both sides of the module base 211. Specifically, the massage balls 212 may roll along the user's body as described below, and the member serving as the axis of rotation of the massage balls 212 may be fixed by the side covers 213. Thus, the rotation axis of the massage balls 212 may be prevented from being separated from the massage part 210.

[0119] Although not shown in the figure, the massage part 210 may further include a vibration motor. The vibration motor may generate vibrations. The vibration motor may transmit the generated vibrations to the massage balls 212. The massage balls 212 may transmit the vibrations to the user's body to provide vibration massage.

[0120] As an embodiment, the massage ball 212 may further include a heating component.

[0121] The heating member can generate heat by receiving electricity. The heating member can be a device for transferring heat to the massage ball 212. For example, the heating member can transfer heat generated by a heating element to the massage ball 212. As one embodiment, the heating element can be disposed within the heating member. The massage ball 212 can transfer heat by contacting the user's body, providing the user with a warm compress massage.

[0122] Figure 6 1 is a perspective view showing a deployable massage device 100 according to an embodiment of the present invention.

[0123] As shown in the figure, a massage device 100 according to one embodiment of the present invention includes: a first frame 110, which serves as the main body of the massage device 100; a second frame 120, which is movable in the longitudinal direction relative to the first frame 110; a driving unit 500, which is disposed on the first frame 110 and provides driving force to the second frame 120; and a link unit 300, which is located between the second frame 120 and the driving unit 500 and moves the second frame 120 according to the driving force of the driving unit 500. The first frame 110 is a structure that includes the massage module 200 and is supported on the ground.

[0124] The driving unit 500 is located at the lower end of the first frame 110 and includes a link unit 300 located between the first frame 110 and the second frame 120. The link unit 300 can be coupled to the driving unit 500 and rotate in response to the longitudinal drive of the driving unit 500, thereby moving the second frame 120 along the longitudinal direction of the first frame 110. As one embodiment of the present invention, the driving unit 500 can be composed of a linear actuator that performs longitudinal movement and can be controlled by the control unit to expand or contract.

[0125] The drive unit 500 is coupled to the hinge portion 115 of the first frame 110. In other words, the hinge portion 115 can be located on the first frame 110 and coupled to the drive unit 500. More preferably, the drive unit 500 is located between the first frame 110 and the ground and on the frame portion 112. The hinge portion 115 allows the extended end of the drive unit 500 to have a predetermined angle in the vertical direction relative to the ground. Specifically, the drive unit 500 is located at the lower end of the first frame 110 and coupled to the hinge portion 115 via the hinge shaft 115a, such that the drive unit 500 is arranged (or coupled) to be movable in the vertical direction.

[0126] Further, the hinge part 115 rotates in the height direction corresponding to the rotation of the first link 310 coupled to the driving part 500 so that the driving part 500 has a predetermined angle.

[0127] In one embodiment, the drive unit 500 comprises a linear actuator and applies a longitudinal driving force to the link unit 300. Furthermore, the linear actuator drive unit 500 is positioned on the first frame 110 via the hinge axis 115a of the hinge unit 115. When the linear actuator is deployed, the drive unit 500 rotates downward relative to the hinge unit 115, causing the lower end of the first link 310 coupled to the drive unit 500 to contact the ground and rotate relative to the frame unit 112. Furthermore, when the drive unit 500 is fully deployed or fully retracted, the drive unit 500 is coupled to the hinge unit 115 so that the drive unit 500 rises at a predetermined angle corresponding to the rotation radius of the first link 310.

[0128] The first frame 110 includes a support portion 111 for installing the massage module 200, a frame portion 112 covering the support portion 111, and upper and lower frame portions 113 provided on the frame portion 112 in the height direction and coupled to the link unit 300. A pad including the massage module 200 may be provided in the support portion 111.

[0129] Furthermore, the frame portion 112 forms the skeleton of the first frame 110. Upper and lower frame portions 113 are arranged in the height direction of at least one of the frame portions 112 and may be provided with the rotation axis portion of the link unit 300. More preferably, the upper and lower frame portions 113 are coupled to the support portion 111 and the frame portion 112 of the first frame 110 and are arranged in the height direction. The rotation axis of the second link 320 may be provided in the upper and lower frame portions 113, wherein the second frame 120 is coupled to one end of the second link 320. Furthermore, the upper and lower frame portions 113 coupled to the second link 320 may include a guide groove 114, allowing one end of the second link 320 to move along the length direction of the upper and lower frame portions 113. In other words, the guide groove 114, into which at least a portion of the second link 320 is inserted, is located in the upper and lower frame portions 113.

[0130] When at least a portion of the second link 320 rotates about one end of the second link 320 located within the guide slot 114, the one end of the second link 320 moves along the guide slot 114, thereby reducing the height movement of the second frame 120 coupled to the other end of the second link 320. More preferably, the one end of the second link 320 inserted into the guide slot 114 is provided with a third shaft 321, and the other end of the second link 320 coupled to the second frame 120 is provided with a fourth shaft 322. Furthermore, the other end of the second link 320 can rotate about the third shaft 321, and the third shaft 321 can move in the height direction along the inside of the guide slot 114.

[0131] The second frame 120 is held in a coupled state with the first frame 110 by the link unit 300 , and rotates and moves along the length direction of the first frame 110 . The second frame 120 includes a rotating portion 122 at one end thereof facing the ground.

[0132] Furthermore, a roller portion 121 is included, which is located on the first frame 110 and in an area where the first frame 110 and the second frame 120 face each other. The guide portion 116 of the second frame 120 is guided in its longitudinal direction by the roller portion 121, which is located at the end of the first frame 110 where the second frame 120 is deployed. More preferably, the guide portion 116 is located at the deployed end of the second frame 120, corresponding to the roller portion 121, and is arranged at a position opposite the roller portion 121 when the second frame 120 moves in a height direction relative to the ground.

[0133] The guide portion 116 may have a predetermined curvature and constitute an end opposite to the roller portion 121 , and may guide the movement of the second frame 120 opposite to the roller portion 121 when the second frame 120 is unfolded or retracted along the upper surface of the first frame 110 .

[0134] According to one embodiment of the present invention, the guide portion 116 is connected to the upper surface of the roller portion 121 when the second frame 120 is unfolded from a retracted state, and the length direction position of the guide portion 116 can be set in a manner such that the roller portion 121 is opposite to the inclined surface of the guide portion 116 at the position where the rotating portion 122 is connected to the ground.

[0135] On the contrary, when the unfolded second frame 120 is folded on the upper surface of the first frame 110, one end of the second frame 120 connected to the second connecting rod 320 at the fourth axis 322 rises along the height direction of the first frame 110, and when the rotating part 122 is separated from the ground, the inclined side of the guide part 116 switches to a position connected to the roller part 121.

[0136] More specifically, when third shaft 321 at one end of second link 320 moves to a position adjacent to the lower end of guide slot 114, fourth shaft 322 at the other end of second link 320, coupled to second frame 120, moves downward. This allows the length and shape of guide portion 116 to be determined in accordance with the timing of interference between first frame 110 and second frame 120. Furthermore, in the present invention, guide portion 116 can be switched to a position where it engages roller portion 121 at the moment when rotating portion 122 separates from the ground.

[0137] The positional relationship between the guide portion 116 and the roller portion 121 can minimize the height change of the second frame 120 in the vertical direction during driving and the interference of the first frame 110 relative to the second frame 120 when the rotating portion 122 is separated from the ground.

[0138] In addition, the roller portion 121 can be composed of at least one roller, so that even when the driving force of the driving portion 500 is applied when the guide portion 116 is connected to the first frame 110, the second frame 120 can be easily moved in both directions in the length direction.

[0139] The connecting rod unit 300 includes a first connecting rod 310 and a second connecting rod 320, wherein the first connecting rod 310 is located between the driving part 500 and the frame part 112, and is combined with the driving part 500 and rotates with the frame part 112 as a reference. The rotation center axis of the second connecting rod 320 is provided in the upper and lower frame parts 113, and the second connecting rod 320 is located between the second frame 120 and the guide groove 114.

[0140] The first link 310 is coupled to an area adjacent to one end of the second link 320 located inside the guide groove 114 and is rotatably coupled with the frame portion 112. Furthermore, the coupling point between the first link 310 and the second link 320 may be adjacent to one end of the second link 320 located inside the guide groove 114.

[0141] The rotational force applied to the second link 320 is provided by the driving unit 500, and one end of the first link 310 coupled to the driving unit 500 moves in the longitudinal direction. The end coupled to the first link 310 and the second link 320 integrally moves in the longitudinal direction by an amount corresponding to the movement of the driving unit 500. As a result, the second frame 120 coupled to the second link 320 rotates and expands in the longitudinal direction of the first frame 110.

[0142] More preferably, in response to the rotation of the second link 320 about the third axis 321, the end of the second frame 120 adjacent to the first frame 110 rotates upward and then expands toward the area opposite the end of the first frame 110. That is, in response to the rotation of the second link 320, the fourth axis 322 of the second frame 120 coupled to the second link 320 can move in a rotational direction about the third axis 321, which is located at one end of the insertion guide groove 114 of the second link 320.

[0143] In addition, the first link 310 is connected to the inner side of the first frame 110 , and the second link 320 is combined with the outer side of the first link 310 . One end of the second link 320 may be located on the second frame 120 .

[0144] In this way, the width of the first link 310 is smaller than the width of the second frame 120 , and the second link 320 extends along the width direction and is located between the first link 310 and the second frame 120 .

[0145] Furthermore, the width of the area where the second link 320 is coupled to the first link 310 is relatively smaller than the width of the second link 320 coupled to the second frame 120. More preferably, the second link 320 can be coupled to the second frame 120 in a bent state along both sides in the width direction, based on the coupling point with the first link 310.

[0146] In another embodiment of the present invention, the width of the first frame 110 is relatively greater than the width of the second frame 120. Furthermore, the rotation center axis of the first link 310 is located on the inner side surface of the first frame 110, and the second link 320 is adjacent to the outer side surface of the first link 310 and located between the first link 310 and the second frame 120. In other words, the second frame 120 is coupled to the inner side surface of the first frame 110 via a link unit, and the second link 320 is located between the outer side surface of the first link 310 coupled to the inner side surface of the first frame 110 and the second frame 120.

[0147] Figure 7 A deployable massage device 100 including a second frame 120 retracted on an upper surface of a first frame 110 is shown as an embodiment of the present invention. Figure 8 The expandable massage device 100 is shown in a state where the driving part 500 is expanded and the second frame 120 is expanded along the first frame 110 .

[0148] like Figure 7 As shown, when the driving portion 500 is provided in a form of being contracted in the length direction, the second frame 120 is configured to wrap at least a portion of the upper surface of the first frame 110 .

[0149] When the drive unit 500 is retracted, the second shaft 312 at one end of the first connecting rod 310 is positioned adjacent to the drive unit 500, and the fourth shaft 322 of the second connecting rod 320, coupled to the second frame 120, is positioned adjacent to the upper surface of the first frame 110. Thus, the second frame 120 is configured to at least partially overlap the upper surface of the first frame 110. Furthermore, when the second frame 120 is positioned on the upper surface of the first frame 110, the flat area of ​​the guide portion 116 contacts the roller portion 121.

[0150] When the driving unit 500 is deployed, the first link 310, coupled to the driving unit 500 via the second shaft 312, is coupled to the second link 320 via the coupling shaft 323 and moves integrally with the driving unit 500. In this case, one end of the first link 310, including the second shaft 312 coupled to the driving unit 500, rotates about the first shaft 311 located on the frame portion 112, and the second frame 120 moves in the deployed length direction.

[0151] According to an embodiment of the present invention, the second frame 120 can be retracted or extended along the inner side of the first frame 110, and the width of the first frame 110 is configured to be relatively larger than the width of the second frame 120. Furthermore, the link unit 300 can be at least partially located between the first frame 110 and the second frame 120.

[0152] In addition, the other end of the second connecting rod 320, including the fourth shaft 322 connected to the second frame 120, rotates with the third shaft 321 as a reference, so that the second frame 120 moves in the longitudinal direction along the end of the first frame 110, and the third shaft 321 is located at one end of the second connecting rod 320 located on the inner side of the guide groove 114.

[0153] Furthermore, when the second frame 120 is located at the highest point (or the highest point (or the largest point) in the height direction of the first frame 110) as the link unit 300 rotates (e.g., the second link 320 rotates), the end of the second link 320 including the third axis 321 is located at the lower end of the guide groove 114 and abuts the lower end of the guide groove 114. In other words, as the end of the second link 320 including the third axis 321 moves up and down along the guide groove 114, the height of the second frame 120 protruding in the height direction of the first frame 110 can be kept relatively low as the second link 320 rotates. In other words, the third axis 321, which serves as the rotational center axis of the second link 320, can move along the guide groove 114 in the height direction of the first frame 110.

[0154] That is, in response to the movement of the driving unit 500, one end of the first link 310 including the second shaft 312 rotates and moves relative to the first shaft 311 located on the first frame 110. Furthermore, the coupling shaft 323 located between the first shaft 311 and the second shaft 312 of the first link 310 moves integrally along the length direction of the first frame 110 in response to the movement of the second shaft 312.

[0155] In addition, in the second link 320 connected to the first link 310 through the coupling shaft 323, the other end of the second link 320 rotates and moves with reference to the third axis 321 located inside the guide groove 114 and movable along the height direction, and the other end of the second link 320 includes a fourth axis 322 connecting the second link 320 and the second frame 120.

[0156] In addition, the other end of the first link 310 having the second shaft 312 is coupled to the extended end of the driving unit 500. When the first link 310 rotates about the first shaft 311, the height of the other end of the first link 310 changes correspondingly to the upward and downward tilt of the driving unit 500 about the hinge shaft 115a.

[0157] Further, the third shaft 321 at one end of the second link 320 moves downward along the length direction of the first link 310 along with the coupling shaft 323 to a position adjacent to the lower end of the guiding groove 114. Therefore, the fourth shaft 322 of the second link 320 coupled to the second frame 120 can be set at a position relatively lower in height than the state where the rotating shaft of the second link 320 rotates.

[0158] When the second frame 120 passes the highest point and continues to unfold, as Figure 8 shown, the other end of the second link 320 switches to a position adjacent to the end in the length direction of the first frame 110, and the second frame 120 remains in a state of unfolding along the outer side surface of the end of the first frame 110.

[0159] In an embodiment of the present invention, the first link 310 includes a second shaft 312 coupled to the driving part 500 and is configured in a "C" shape with both side surfaces extending upward. Further, the links extending to both sides of the first link 310 are combined such that the link coupled to the driving part 500 can rotate with respect to the frame part 112 as a reference. When the driving part 500 contracts, the area coupled to the driving part 500 rotates with respect to the both side surfaces coupled to the frame part 112 so as to move to a position adjacent to the driving part 500. Further, the second link 320 coupled to the first link 310 is configured such that the other end coupled to the second link 320 rotates to a position adjacent to the upper surface of the first frame 110 with respect to the guiding groove 114 of the upper and lower frame parts 113 as a reference.

[0160] On the contrary, when the driving part 500 unfolds, with respect to the both side surfaces of the first link 310, the lower end rotates and moves in the direction in which the second frame 120 unfolds, and the second link 320 coupled to the first link 310 also moves integrally in the same direction. In this case, the second link 320 rotates with the end coupled to the guiding groove 114 as a center, and the other end coupled to the second frame 120 rotates with respect to the center. Further, the position of the end of the second link 320 located inside the guiding groove 114 can correspond to the change in height of the rotation of the second link 320.

[0161] Therefore, the rotation center axis of the second link 320 can move along the guiding groove 114. More preferably, when the second frame 120 is at the highest point along the upper surface of the first frame 110, the third shaft 321 serving as the rotation center axis of the second link 320 can be in contact with the lower end of the guiding groove 114.

[0162] Furthermore, in response to the extension or contraction of the drive unit 500, the roller portion 121 located at the end of the first frame 110 is configured to oppose the guide portion 116 formed at the end of the second frame 120. For example, when the second frame 120 is deployed, the rotating portion 122 located at the lower end of the second frame 120 rotates, causing the second frame 120 to move along the ground. The rotational force of the roller portion 121 opposing the guide portion 116 located on the back of the second frame 120 allows the second frame 120 to deploy along the length of the first frame 110. In other words, the rotating portion 122 can be located on the second frame 120, causing the second frame 120 to move along the ground.

[0163] In this way, the control unit can control the length of the driving unit 500 coupled to the first link 310 to expand or contract, and expand the second frame 120 located on the upper surface of the first frame 110 along the length direction of the first frame 110 .

[0164] Figure 9 A link unit 300 including a first groove 324 located in a second link 320 is shown as an embodiment of the present invention.

[0165] One end of the second connecting rod 320, including the third axis 321, is located inside the guide slot 114 provided in the upper and lower frame portions 113. The other end of the second connecting rod 320, including the fourth axis 322, rotates integrally with the second frame 120 about the third axis 321. Therefore, the second frame 120 receives the driving force from the driving unit 500, causing it to move along the length of the first frame 110. Furthermore, when the second frame 120 is at its highest point relative to the height of the upper surface of the first frame 110, the third axis 321 of the second connecting rod 320, located within the guide slot 114, moves to a position where it connects with the lower end of the guide slot 114, thereby lowering the height of the second frame 120's highest point.

[0166] Furthermore, the other end of the second link 320 may include a first slot 324 formed at a location where it is coupled to the second frame 120. The fourth shaft 322, which rotationally couples the second link 320 to the second frame 120, is configured to slide along the first slot 324 of the second link 320 in the lengthwise direction of the second link 320. In other words, the first slot 324 is located in the second link 320, and the fourth shaft 322, which couples the second frame 120 and the second link 320, is coupled to the first slot 324 and can move along the lengthwise direction of the second link 320.

[0167] Therefore, when the first link 310 receives a driving force and the other end of the second link 320, which is coupled to the second frame 120, reaches its highest point in the height direction, one end of the second link 320 shifts to a position where it contacts the lower end of the guide slot 114, thereby lowering the maximum height of the second link 320. Furthermore, the fourth shaft 322, which couples the second link 320 to the second frame 120, can slide along the first slot 324 along the length of the second frame 120. In other words, when the second frame 120 moves in the height direction, the second link 320 moves downward along the guide slot 114, and simultaneously, the second frame 120 can move downward along the first slot 324 of the second link 320.

[0168] In this way, the present invention may include a first groove 324 located at the second connecting rod 320 and a guide groove 114 for setting the third axis of the second connecting rod 320, so that even when the second connecting rod 320 is unfolded corresponding to the length direction of the driving part 500, the height of the highest point of the second frame 120 can be relatively lowered.

[0169] Figures 10 to 12 A deployable massage device 100 including a single link unit 300 is shown as another embodiment of the present invention.

[0170] like Figure 10 , the second frame 120 is shown as being retracted on the upper surface of the first frame 110. In another embodiment, a single link structure is included to switch the deployed state of the driving portion 500 to the retracted state of the second frame 120.

[0171] Specifically, the driving unit 500 coupled to the first frame 110 via the hinge 115 is coupled to the second frame 120 via a link unit 300 comprised of a single link located on the upper and lower frame portions 113. The link unit 300, comprised of a single link, includes one end coupled to the driving unit 500 and the other end coupled to the second frame 120 via a sub-link 330. Both ends rotate with respect to the upper and lower frame portions 113.

[0172] The secondary link 330 is located between one end of the first link 310 and the second frame 120 and includes a first secondary shaft 333 that moves along a third slot 332 located in the first frame 110. Furthermore, the secondary link 330 includes a second secondary shaft 334 located at one end coupled to the second frame 120.

[0173] The third slot 332 is provided in the longitudinal direction of the first frame 110. More preferably, the first secondary shaft 333 is rotatably coupled to the upper end of the first link 310 and is disposed within the third slot 332 in a manner that restricts movement in the height direction. Therefore, the end of the secondary link 330 provided with the first secondary shaft 333 can only move in the longitudinal direction along the third slot 332 of the first frame 110.

[0174] Furthermore, when the driving unit 500 is extended, the second frame 120 is moved to a position at least partially overlapping the upper surface of the first frame 110 through the link unit 300. That is, when the driving unit 500 is deployed, the second frame 120 is located on the upper surface of the first frame 110.

[0175] The first link 310 rotates around a first shaft 311 located on the upper and lower frame parts 113 , and a first sub-shaft 333 located at one end of the sub-link 330 slides along a second groove 331 provided in the longitudinal direction of the first link 310 .

[0176] Then, if Figure 11 As shown, when the driving unit 500 begins to retract, the lower end of the first link 310 rotates around the first axis 311 of the upper and lower frame parts 113 via the second axis 312. Furthermore, the upper end of the first link 310 coupled to the auxiliary link 330 rotates toward the direction in which the second frame 120 expands.

[0177] The ends of the secondary link 330 are respectively coupled to one end of the second frame 120 and the upper end of the first link 310, and both ends are freely rotatable. Furthermore, in response to the contraction driving force of the drive unit 500, the secondary link 330 coupled to the end of the second frame 120 can maintain the end of the second frame 120 at the same or relatively lower position than the end of the link unit 300, even when the end of the link unit 300 is at its highest point. More preferably, the first secondary shaft 333 of the secondary link 330, which is arranged to be inserted into the inside of the second groove 331 in the first link 310, is constrained by the third groove 332 and maintained at the same height. In response to the height-direction rotation of the upper end of the first link 310, the first secondary shaft 333 can slide and move into the inside of the second groove 331.

[0178] In addition, if Figure 12 As shown, when the second frame 120 is unfolded, the secondary link 330 extends downward from the end of the second link 320 in the height direction so as to maintain the same height as the pad located on the upper surface of the support portion 111 .

[0179] That is, the sub-link 330 is coupled to the end of the first link 310 through the first sub-shaft 333 , so that the height of the second frame 120 can be changed relative to the end of the first link 310 .

[0180] Figures 13 and 14 A structure of a second frame 120 inserted into and ejected from the first frame 110 is shown as another embodiment of the present invention.

[0181] In the illustrated embodiment, the first frame 110 is hollow, and one end of the first frame 110 that exits the second frame 120 is open. The driving unit 500 is located inside the hollow of the first frame 110 and is configured to extend and retract along the length direction.

[0182] Furthermore, a bracket 600 is included, which is located between the drive unit 500 and the second frame 120 and moves integrally with the drive unit 500 along the length of the hollow interior of the first frame 110. The bracket 600 includes at least two connecting rods coupled to the second frame 120, and the bracket 600 moves along a guide rail formed in the hollow interior of the first frame 110. Furthermore, the connecting rods located between the second frame 120 and the bracket 600 move along an expansion slot 700 formed in the hollow side of the first frame 110. As the second frame 120 is ejected, the second frame 120 rotates and rises in height relative to the bracket 600.

[0183] More preferably, two connecting rods are provided between the bracket 600 and the second frame 120, and the connecting rod at the upper end may include a protrusion that is inserted into the inner side of the expansion groove 700. Therefore, the connecting rod including the protrusion moves along the bent expansion groove 700 in response to the longitudinal movement of the bracket 600, so that the connecting rod can rotate, causing the second frame 120 to rise.

[0184] The protrusion is located between the bracket 600 and the second frame 120. When the protrusion moves along the inside of the expansion groove 700, the end connected to the second frame 120 rotates in the upward direction relative to the bracket 600. In addition, in response to the rotation of the connecting rod including the protrusion, the other adjacent connecting rod can rotate integrally in the upward direction of the second frame 120 and be supported.

[0185] The expansion slot 700 is formed along the length direction. In addition, the expansion slot 700 includes an inclined area with a predetermined angle in the height direction in the area adjacent to the hollow open end. When the protrusion moves along the inclined area, the other end of the connecting rod including the protrusion can rotate upward with the bracket 600 as a reference. That is, as the other end of the connecting rod connected to the second frame 120 rotates upward, the second frame 120 can rise horizontally in the height direction compared to the stowed state. More preferably, the expansion slot 700 is formed so that after the second frame 120 protrudes from the hollow open area, the protrusion enters the inclined area, thereby causing the second frame 120 protruding from the outside of the first frame 110 to rise in the height direction.

[0186] In this way, the connecting rod including the protrusion is located between the bracket 600 and the second frame 120 and can move along the expansion groove 700 formed on the inner side surface of the hollow of the first frame 110. In addition, when the second frame 120 protrudes from the outer side of the hollow of the first frame 110, the protrusion moves along the inclined area of ​​the expansion groove 700, causing the connecting rod coupled to the second frame 120 to rotate with the bracket 600 as a reference. As a result, the second frame 120 can move upward in the height direction to substantially correspond to the upper surface of the first frame 110.
