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 movably coupled with the first frame as a reference; a guide rail portion located on the first frame and guiding a movement path of the second frame; and a driving part which provides driving force to the second frame so as to enable the second frame to move along the guide rail part.

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 with high time and cost-effectiveness have been introduced. Any tool, device, or apparatus that mechanically provides massage 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, safely provide massage to the user's body, and further can provide massage to the user's body more effectively. Summary of the Invention

[0073] Hereinafter, embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings.

[0074] Figure 1 FIG. 1 is a diagram illustrating 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 FIG. 1 is a diagram illustrating an example of driving the deployable massage device 100 .

[0075] Reference 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 .

[0076] 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.

[0077] 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.

[0078] The first frame 110 may include an upper surface on which a user can lie. For example, the user may lie on the upper surface of the first frame 110 to receive a massage.

[0079] 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.

[0080] The end of the first frame 110 away from the second frame 120 may include a bent portion 400 (see FIG. Figure 8 The bending portion 400 may be located on 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.

[0081] 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.

[0082] 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.

[0083] The massage module 200 may move in at least one direction of a length direction of the first frame 110 and a height direction of the first frame 100 and massage at least a portion of a user's body.

[0084] The massage module 200 can directly or indirectly contact the user's body to 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.

[0085] 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.

[0086] 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.

[0087] However, the massage modes provided by the massage module 200 are not limited thereto.

[0088] 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.

[0089] 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.

[0090] The massage module 200 may be disposed inside the support portion of the first frame 110 , and at least a portion thereof may be exposed to the outside through a massage groove formed on the upper surface.

[0091] 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.

[0092] 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.

[0093] 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 separate 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.

[0094] 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.

[0095] 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.

[0096] 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).

[0097] The second frame 120 may support the leg portion that is not supported by the first frame 110 when the user lies on the upper surface of the first frame 110 .

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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 types of hardware may also be used for implementation.

[0102] 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.

[0103] 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 movement of the plurality of actuators.

[0104] 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 .

[0105] 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.

[0106] 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 .

[0107] 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 .

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] Figure 5 It shows Figure 4 FIG. 210 of the massage part.

[0113] Referring to the drawings, the massage part 210 may include at least one of a module base 211 , massage balls 212 , a side cover 213 , and an upper cover 214 .

[0114] 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.

[0115] 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.

[0116] 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.

[0117] As an embodiment, the massage ball 212 may further include a heating component.

[0118] 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 inside the heating member. The massage ball 212 can transfer heat by contacting the user's body, providing the user with a warm compress massage.

[0119] Figure 6 A perspective view of a deployable massage device 100 according to an embodiment of the present invention is shown.

[0120] As shown in the figure, the 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 can move along the length direction based on the first frame 110; a guide rail portion 700 (refer to Figure 7 ), located in the first frame 110 and used to guide the movement path of the second frame 120; and / or the driving unit 500, providing a driving force to the second frame 120 so that the second frame 120 moves along the guide rail portion 700. The first frame 110 is a structure including the massage module 200 and supported on the ground.

[0121] The driving part 500 is located at the lower end of the first frame 110 and includes a connecting rod unit 300 located between the first frame 110 and the second frame 120. The connecting rod unit 300 can be combined with the driving part 500 and rotated corresponding to the drive of the driving part 500 in the longitudinal direction, so that the second frame 120 moves along the longitudinal direction of the first frame 110. As an embodiment of the present invention, the driving part 500 can be composed of an actuator or a motor that performs longitudinal movement. Further, the actuator includes a bracket 600 that moves along the guide rail part 700 described later in the longitudinal direction of the guide rail part 700, and is configured to transmit a driving force to the guide rail part 700 through a controller. The guide rail part 700 may have a screw rod structure, and when the motor applies a driving force, the bracket 600 combined with the guide rail part 700 having the screw rod structure can reciprocate along the longitudinal direction of the guide rail part 700. That is, when the driving force of the driving part 500 is applied, the screw rod structure rotates, and the bracket 600 may move along the guide rail part 700 corresponding to the rotation of the guide rail part 700 of the screw rod structure.

[0122] In other words, the link unit 300 is coupled to the bracket 600 that moves along the guide rail portion 700 and transmits a driving force to the second frame 120 to move the second frame 120 along the length direction of the first frame 110 .

[0123] The guide rail portion 700 is configured to be coupled to the hinge portion 115 of the first frame 110. More preferably, the drive unit 500 is positioned between the first frame 110 and the ground, and the hinge axis 115a of the hinge portion 115 allows one end of the guide rail portion 700 to have a predetermined vertical angle relative to the ground. Specifically, the guide rail portion 700 is positioned at the lower end of the first frame 110 and coupled to the hinge portion 115 via the hinge axis 115a, allowing the drive unit 500 to be arranged (or coupled) to move vertically.

[0124] Furthermore, the first link 310 is coupled to the bracket 600 that moves in the longitudinal direction along the guide rail 700, and the hinge 115 is rotatable in the height direction, so that the driving unit 500 has a predetermined angle corresponding to the vertical movement of the driving unit 500 and the guide rail 700. The hinge 115 is located on the first frame 110 and coupled to the guide rail 700 via a hinge shaft 115a.

[0125] As one embodiment, the drive unit 500, comprising an actuator or motor coupled to the guide rail 700, is positioned on the first frame 110 via a hinge 115. When the actuator is deployed or the motor is driven, the bracket 600, located on the guide rail 700, moves longitudinally along the guide rail 700. Furthermore, the drive unit 500 rotates downward relative to the hinge 115, so that the lower end of the first link 310 coupled to the bracket 600 is adjacent to the ground and can rotate relative to the frame 112. Furthermore, when the drive unit 500 fully deploys or retracts the bracket 600, the drive unit 500 can rotate relative to the hinge axis 115a, causing the drive unit 500 to rise by a predetermined angle corresponding to the rotation radius of the first link 310.

[0126] 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.

[0127] Furthermore, the frame portion 112 constitutes the skeleton of the first frame 110. Upper and lower frame portions 113 are provided in the height direction of at least one of the frame portions 112, and the rotation axis portion of the connecting rod unit 300 may be located on the upper and lower frame portions 113. More preferably, the upper and lower frame portions 113 may be coupled between the support portion 111 of the first frame 110 and the frame portion 112 and disposed in the height direction. Furthermore, the upper and lower frame portions 113 may be provided with a rotation center axis for the second connecting rod 320, wherein the second frame 120 is coupled to one end of the second connecting rod 320. Furthermore, the upper and lower frame portions 113 coupled to the second connecting rod 320 may include a guide groove 114, allowing one end of the second connecting rod 320 to move along the length direction of the upper and lower frame portions 113. That is, the guide groove 114, into which at least a portion of the second connecting rod 320 is inserted, may be located on the upper and lower frame portions 113.

[0128] The second link 320 is configured to rotate with one end located within the guide slot 114 formed of an elongated hole as a reference, thereby reducing the height movement of the second frame 120 coupled to the other end of the second link 320. The guide slot 114 may include a rail shape configured to enable the second link 320 to slide within the upper and lower frame portions 113. More preferably, the guide slot 114 is configured to be integrally formed with the upper and lower frame portions 113, allowing the rotation axis of the second link 320 to slide along the guide slot 114. The rotation axis of the second link 320 is located within the upper and lower frame portions 113, and when the first link 310 moves along the bracket 600, the rotation axis of the second link 320 changes.

[0129] The second frame 120 is connected to the first frame 110 via the link unit 300 and rotates and moves along the length of the first frame 110. The second frame 120 includes a rotating portion 122 at one end thereof, which is opposite to the ground. Furthermore, the rotating portion 122 is positioned on the second frame 120 and moves the second frame 120 along the ground. The rotating portion 122 may be in the form of rollers for guiding the movement of the second frame 120.

[0130] In addition, a roller portion 121 is included, which is located on the first frame 110 and located in a region where the first frame 110 and the second frame 120 face each other. For example, the roller portion 121 may be located at one end of the first frame 110 where the second frame 120 is unfolded.

[0131] The guide portion 116 of the second frame 120 can be configured to be guided to move in the length direction by the roller portion 121 provided on the first frame 110. Furthermore, the guide portion 116 is located at one end of the second frame 120 and is provided corresponding to the roller portion 121. The guide portion 116 can be arranged at a position opposite to the roller portion 121 when the second frame 120 moves in the height direction of the ground.

[0132] The guide portion 116 has a predetermined curvature and one end thereof faces the roller portion 121 , and can guide the movement of the second frame 120 facing the roller portion 121 when the second frame 120 is unfolded or retracted on the upper surface of the first frame 110 .

[0133] As an embodiment of the present invention, the guide portion 116 contacts the upper surface of the roller portion 121 when the second frame 120 is unfolded from a retracted state, and the longitudinal position of the guide portion 116 is set in a position where the rotating portion 122 contacts the ground so that the roller portion 121 and the inclined surface of the guide portion 116 are opposite to each other.

[0134] On the contrary, when the unfolded second frame 120 is retracted on the upper surface of the first frame 110, one end of the second frame 120 connected to the second connecting rod 320 on 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.

[0135] More specifically, when third shaft 321 at one end of second link 320 moves toward 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 interfaces with roller portion 121 at the moment when rotating portion 122 is separated from the ground.

[0136] 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 with the second frame 120 when the rotating portion 122 is separated from the ground.

[0137] 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.

[0138] The link unit 300 includes a first link 310 and a second link 320. The first link 310 is coupled to the bracket 600 located on the guide rail portion 700 and rotates relative to the frame portion 112. The second link 320 is coupled to the first link 310 and is located between the second frame 120 and the upper and lower frame portions 113 (e.g., the guide groove 114). The second link can be configured to rotate relative to the upper and lower frame portions 113.

[0139] 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 to the frame portion 112. Furthermore, the coupling point between the first link 310 and the second link 320 may be located adjacent to one end of the second link 320 located inside the guide groove 114. Furthermore, the first link 310 may be rotatably coupled to a rotating bracket 112a protruding from the upper end of the frame portion 112, with the first axis 311 as a reference. Furthermore, the end of the first link 310 coupled to the frame portion 112 may be positioned relatively higher than the third axis 321, which couples the second link 320 to the upper and lower frame portions 113.

[0140] The rotational force applied to the second link 320 is applied by the bracket 600 moving along the guide rail portion 700. The second shaft 312 of the first link 310 coupled to the bracket 600 moves in the longitudinal direction, and the coupling shaft 323 coupling the first link 310 and the second link 320 moves in accordance with the amount of movement of the bracket 600. As a result, the second frame 120 coupled to the second link 320 rotates and expands along the longitudinal direction of the first frame 110.

[0141] More preferably, in response to the second link 320 rotating about the third axis 321, the second frame 120 coupled to the fourth axis 322 of the second link 320 rotates and moves in the height direction at one end adjacent to the first frame 110, and then expands toward the area opposite the distal end of the first frame 110. In other words, 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 the direction of rotation about the third axis 321 located at one end of the insertion guide groove 114 of the second link 320.

[0142] As an embodiment of the present invention, the first frame 110 is relatively wider than the second frame 120. Furthermore, the rotation center axis of the first connecting rod 310 is located on the inner side of the first frame 110, and the second connecting rod 320 is adjacent to the outer side of the first connecting rod 310 and is located between the first connecting rod 310 and the second frame 120.

[0143] In other words, the second frame 120 is coupled to the inner side of the first frame 110 through the link unit 300 , and the second link 320 may be located between the outer side of the first link 310 coupled to the inner side of the first frame 110 and the second frame 120 .

[0144] Figure 7 The connection relationship of the driving unit 500 as one embodiment of the present invention is shown.

[0145] The drive unit 500 is located on the frame portion 112 of the first frame 110, which is close to the ground. Furthermore, the drive unit 500 is coupled to the frame portion 112 via the hinge portion 115, allowing the guide rail portion 700 to be spaced apart vertically by a predetermined angle. In the guide rail portion 700, when the lower end of the first link 310 moves toward the ground relative to the hinge axis 115a of the hinge portion 115, the drive unit 500 can move downward. When the lower end of the first link 310 is fully extended or retracted, the drive unit 500 can move upward.

[0146] Furthermore, the hinge portion 115 may include a hinge bracket located on the frame portion 112 of the first frame 110, and a hinge shaft 115a into which at least a portion of the driving portion 500 or the guide rail portion 700 is inserted and integrated. Thus, the driving portion 500 or the guide rail portion 700 can rotate vertically at a predetermined angle relative to the hinge bracket, which is integrated with the hinge shaft 115a. Consequently, when the bracket 600 coupled to the first link 310 moves along the guide rail portion 700, the guide rail portion 700 can tilt relative to the hinge bracket.

[0147] The front end of the driving unit 500 includes a guide rail portion 700 formed along the length of the first frame 110. The guide rail portion 700 includes a bracket 600 that slides along the guide rail portion 700 in response to the longitudinal drive of the driving unit 500. The bracket 600 is rotatably coupled to the lower end of the first connecting rod 310, allowing the first connecting rod 310 and the bracket 600 to move integrally. The guide rail portion 700 is configured to have a spiral rod structure, and the bracket 600 can move in the longitudinal direction along the guide rail portion 700 of the spiral rod structure.

[0148] In another embodiment of the present invention, the bracket 600 is inserted into and fixed in the inner side of the groove 710 located on both sides of the guide rail portion 700, and receives the longitudinal driving force of the driving portion 500 to move the guide rail portion 700 along the groove 710 in the longitudinal direction.

[0149] In addition, the bracket 600 is coupled to one end of the first link 310 so that the coupled end can move integrally. The upper end of the first link 310 is rotatably coupled to the first frame 110, and the first link 310 moves integrally along the length direction in response to the movement of the bracket 600.

[0150] Figures 8 to 10 The massage device 100 is shown as an embodiment of the present invention in which the second frame 120 is moved from a stowed state along the length direction of the first frame 110 .

[0151] first, Figure 8 The deployable massage device 100 is shown with the second frame 120 in a retracted state.

[0152] When the bracket 600 is positioned adjacent to the driving unit 500 on the guide rail 700, the second frame 120 is positioned such that at least a portion of the upper surface of the first frame 110 faces the back surface of the second frame 120. Furthermore, the first link 310 coupled to the bracket 600 moves integrally with the bracket 600 to a position adjacent to the driving unit 500.

[0153] In the retracted state, at least a portion of the second frame 120 is positioned opposite the upper surface of the first frame 110, and the rotating portion 122 is located at the end of the second frame 120, spaced apart from the ground. Furthermore, the width of the second frame 120 is smaller than that of the first frame 110. In the retracted state, the second frame 120 is positioned adjacent to the inner side of the first frame 110. That is, when the bracket 600 is located at the end of the guide rail portion 700 adjacent to the driving portion 500, the second frame 120 is located on the upper surface of the first frame 110.

[0154] Thereafter, when the driving force of the driving portion 500 is applied to the bracket 600 (for example, when the bracket 600 is located at the end of the guide rail portion spaced apart from the driving portion 500), as shown in FIG. Figure 9 As shown, the second frame 120 is spaced apart from the upper surface of the first frame 110 and is expanded (or moved) in the length direction of the first frame 110 .

[0155] The bracket 600 moves along the guide rail 700 in response to the driving of the driving unit 500. Furthermore, when the lower end of the first link 310 coupled to the bracket 600 moves downward, the driving unit 500 and the guide rail 700 can be integrally tilted downward with respect to the hinge shaft 115a.

[0156] Furthermore, the other end of the second link 320 is coupled to the front end of the second frame 120 via a fourth axis 322. The second link 320 rotates about the third axis 321, thereby integrally rotating and moving along the upper surface of the first frame 110. More preferably, when the first link 310, the second link 320, and the upper and lower frame portions 113 overlap, the end of the second frame 120 coupled to the second link 320 can be located at the highest point. That is, when the second frame 120 is at its highest point in the height direction as the link unit rotates, the end of the second link 320 including the third axis 321 is located at the lower end of the guide slot 114.

[0157] Furthermore, when the first link 310 and the second link 320 overlap in the height direction in a manner consistent with the upper and lower frame portions 113, one end of the second link 320 switches to a position where it contacts the inner lower end of the guide groove 114. Therefore, the second frame 120 coupled to the other end of the second link 320 can provide a protrusion having a height substantially the same as that of the frame portion 112.

[0158] The outer side surface of the first link 310 and the inner side surface of the second link 320 are combined with each other, and the end of the second link 320 is combined with the second frame 120, so that the first link 310 and the second link 320 can be switched to a position overlapping with the upper and lower frame parts 113 on the side.

[0159] That is, one end of the first link 310 including the second shaft 312 rotates and moves with respect to the first shaft 311 located on the rotating bracket 112a in response to the movement of the bracket 600. Furthermore, the coupling shaft 323, which is located between the first shaft 311 and the second shaft 312 of the first link 310 and coupled to the second link 320, moves along the length direction of the first frame 110 in response to the movement of the bracket 600.

[0160] 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 including the fourth shaft 322 rotates and moves with reference to the third shaft 321 that can move along the height direction inside the guide groove 114, wherein the fourth shaft 322 is coupled to the second link 320 and the second frame 120.

[0161] Furthermore, the other end of the first link 310 provided with the second shaft 312 is coupled to the bracket 600. When the first link 310 rotates about the first shaft 311, the height of the other end of the first link 310 can change in accordance with the vertical tilt of the guide rail 700 about the hinge shaft 115a.

[0162] Furthermore, the third shaft 321 located at one end of the second link 320 moves to a position adjacent to the lower end of the guide groove 114 when the coupling shaft 323 moves downward in the longitudinal direction along the first link 310. Therefore, the height of the fourth shaft 322 of the second link 320 coupled to the second frame 120 can be lower than the height when the second link 320 is rotated with the rotation axis of the second link 320 fixed.

[0163] Then, Figure 10 The deployable massage device 100 is shown with the second frame 120 in the deployed state.

[0164] When the driving force of the driving unit 500 is applied, causing the bracket 600 to expand in the longitudinal direction along the guide rail portion 700, one end of the first link 310, including the second shaft 312, coupled to the bracket 600, rotates around the first shaft 311 coupled to the other end of the frame portion. More preferably, the first link 310 is coupled to a rotating bracket 112a protruding from the upper end of the frame portion 112, and the first shaft 311 may be provided therein.

[0165] Furthermore, the second link 320 coupled to the first link 310 integrally moves along the lengthwise direction of the bracket 600. More preferably, the first link 310 is adjacent to one end of the second link 320 located inside the guide slot 114 and rotatably coupled thereto. The second link 320 moves in accordance with the lengthwise direction of the first link 310, while the other end of the second link 320 coupled to the second frame 120 rotates relative to the one end of the second link 320 located inside the guide slot 114. More specifically, the coupling shaft 323 coupling the first link 310 and the second link 320 is driven by the driving force of the driving unit 500 and moves along the lengthwise direction of the first frame 110. The fourth shaft 322 coupling the second link 320 and the second frame 120 is located adjacent to the distal end of the first frame 110.

[0166] In addition, when the second frame 120 moves along the upper surface of the first frame 110 from the retracted state, the second link 320 including the coupling shaft 323 moves downward in the height direction of the first frame 110 while performing a lengthwise movement. In addition, one end of the second link 320 including the third shaft 321 moves downward in the height direction.

[0167] Furthermore, when the second frame 120 is switched to the expanded state at the end of the first frame 110 along the upper surface of the first frame 110, the second link 320 including the coupling shaft 323 moves upward in the height direction while performing a lengthwise movement. In addition, one end of the second link 320 including the third shaft 321 moves upward in the height direction.

[0168] Therefore, the fourth shaft 322 of the second link 320 coupled to the second frame 120 moves along the upper surface of the first frame 110 in an elliptical shape.

[0169] Furthermore, the guide groove 114 is formed as a long hole in the vertical direction on the upper and lower frame parts 113, so that the height direction position of the third axis 321 of the second link 320 can be changed. Figure 9 As shown, when the second frame 120 is at the highest point, the third shaft 321 of the second link 320 located in the guide groove 114 is switched to a position opposite to the lower end of the guide groove 114 .

[0170] Then, if Figure 10 As shown, when the second frame 120 is unfolded, the third axis 321 of the second link 320 is located at a neutral position of the guide groove 114 (a position not adjacent to both ends of the guide groove 114) or a position adjacent to the upper end. More preferably, as Figure 8 and Figure 10 As shown, one end of the second link 320 is disposed inside the guide groove 114 at the same height when the second frame 120 is retracted or the second frame 120 is fully extended.

[0171] In contrast, when the second frame 120 performs the lengthwise movement, one end of the second link 320 may be switched to a state adjacent to the lower end of the guide groove 114. Figure 9 As shown, when moving in the length direction along the first frame 110 , the second frame 120 may move with a relatively low height compared to the length of the second link 320 .

[0172] In summary, when the second frame 120 moves in the longitudinal direction, it rotates about the end of the second link 320 containing the third axis 321. Furthermore, the end of the second link 320 containing the third axis 321 moves downward in the height direction of the first frame 110 in response to the rotation of the first link 310, and then rises again. That is, during the deployment of the second frame 120, the third axis 321, which serves as the rotational axis of the second link 320, is configured so that its position can change in the height direction of the first frame 110.

[0173] Figures 11 to 12 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.

[0174] In the illustrated embodiment, the first frame 110 is hollow inside, and one end thereof is open for ejecting the second frame 120. The driving unit 500 is located inside the hollow of the first frame 110 and is extendable along the length direction.

[0175] Furthermore, the first frame 110 includes a bracket 600, 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 along the length of 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 side surface of the hollow interior 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.

[0176] More preferably, two connecting rods are provided between the bracket 600 and the second frame 120. The connecting rod at the upper end may include a protrusion that is inserted into the inner side of the expansion groove 700. Thus, the connecting rod including the protrusion moves along the curved expansion groove 700 in response to the longitudinal movement of the bracket 600, thereby rotating the connecting rod and causing the second frame 120 to rise. The expansion groove 700 may include an upwardly curved portion located adjacent to the opening along the longitudinal direction of the inner side of the first frame 110 through which the second frame 120 is ejected.

[0177] 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 support it.

[0178] The expansion groove 700 is formed in the length direction. Furthermore, the expansion groove 700 includes an inclined area with a predetermined angle in the height direction in an area adjacent to one end of the hollow opening. 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 coupled to the second frame 120 rotates upward, the second frame 120 can be relatively horizontally raised in the height direction compared to the retracted state. More preferably, after the second frame 120 is discharged from the hollow opening area, the expansion groove 700 is formed so that 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.

[0179] Thus, 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 is ejected from the outer side of the hollow of the first frame 110, the protrusion moves in the inclined area of ​​the expansion groove 700, thereby rotating the connecting rod connected to the second frame 120 with respect to the bracket 600. As a result, the second frame 120 can be moved upward in the height direction to substantially correspond to the upper surface of the first frame 110.

[0180] The above detailed description is an example of the present invention.
