[0102] The fixed wheel 3120 can be formed from a gear with gear teeth formed on its outer peripheral surface.

[0103] The swing frame 3200 is coupled to and supported on the support shaft 3110, allowing it to rotate horizontally relative to the seat frame.

[0104] The swing frame 3200 includes a support shaft connection portion 3210 connected to the support shaft 3110. The support shaft connection portion 3210 is formed as a hole for the support shaft 3110 to be inserted.

[0105] According to one embodiment of this disclosure, the support shaft 3110 can be non-rotatably fixed to the support shaft frame 1260. The swing frame 3200 can rotate with respect to the support shaft connection portion 3210 connected to the fixed support shaft 3110. At this time, a bearing 3212 can be disposed in the hole forming the support shaft connection portion 3210.

[0106] The swing frame 3200 is provided with a connecting bracket 3220, and the leg massage unit 2000 is connected to the connecting bracket 3220 at a position opposite to the support shaft connecting part 3210. The connecting brackets 3220 are arranged in pairs, spaced apart from each other, on the front surface 3202 of the swing frame 3200, and the leg massage unit rotation shaft 2010, protruding from both sides of the leg massage unit 2000, is rotatably inserted into and supported in the connecting bracket 3220. The connecting bracket 3220 is configured such that its upper surface is detachable relative to its lower surface to facilitate the assembly of the leg massage unit 2000. When the vertical rotation of the leg massage unit 2000 is adjusted by the leg angle adjustment part 3500, the leg massage unit rotation shaft 2010 rotates relative to the connecting bracket 3220, simultaneously achieving vertical rotation of the leg massage unit 2000.

[0107] The swing drive unit 3300 provides driving force to make the leg massage unit 2000 rotate horizontally with reference to the support shaft 3110. Figure 4 The state of the swing frame 3200 with the upper surface removed is shown to illustrate the configuration of the swing drive unit 3300.

[0108] According to one embodiment of this disclosure, a swing drive unit 3300 is disposed on a swing frame 3200. The swing drive unit 3300 includes a swing drive motor 3310 and a worm gear 3320.

[0109] The swing drive motor 3310 provides driving force so that the swing frame 3200 can rotate horizontally relative to the support shaft 3110 in a state supporting the leg massage part 2000.

[0110] The swing drive unit 3300 is disposed in the space 3230 formed inside the swing frame 3200. The swing frame 3200 includes the space 3230 between the main body formed by the front surface 3202, the upper surface, and the lower surface 3204.

[0111] A swing drive motor 3310 is disposed on the lower surface 3204 of the swing frame 3200. One side of the swing drive motor 3310 is fixed to the motor fixing clamp 3235. A worm gear 3320 is connected to the motor shaft of the swing drive motor 3310. A worm gear shaft 3311 connected to the motor shaft is provided on the worm gear 3320, and the other side is rotatably fixed to the shaft fixing clamp 3236.

[0112] The worm gear 3320 is connected to guide the swing frame 3200 to move relative to the fixed wheel 3120 when the swing drive motor 3310 rotates.

[0113] The worm gear 3320 and the fixed gear 3120 are arranged in an alternating manner so that the worm gear 3320 is configured to mesh with a gear formed on the outer peripheral surface of the fixed gear 3120.

[0114] The support shaft 3110 and the fixed wheel 3120 are configured in a fixed state, so when the worm gear 3320 rotates by the oscillating drive motor 3310, the oscillating frame 3200, which is connected to the oscillating drive unit 3300 including the worm gear 3320, rotates in the horizontal direction under the guidance of the fixed wheel 3120.

[0115] Since the rotation of the swing drive motor 3310 is converted into the rotation of the swing frame 3200 relative to the support shaft 3110 by the swing adjustment unit 3100, the leg massage unit 2000 attached to the swing frame 3200 can rotate in the horizontal direction along the left and right directions.

[0116] The rotation of the swing drive motor 3310 is controlled by the control unit, and the forward and reverse rotation of the swing drive motor 3310 is converted into the left and right rotation of the leg massage unit 2000. In order to accurately control the rotation of the swing drive motor 3310 and to sense the rotation of the swing drive motor 3310, sensors such as encoders can be installed.

[0117] According to one embodiment of this disclosure, when the swing drive unit 3300 is disposed on the swing frame 3200, it is relatively advantageous for the space utilization of the seat frame 1250, which is equipped with various components. In addition, since the swing drive unit 3300 is integrally integrated with the swing frame 3200 and modularized, that is, forming an assembled unit component, the assembly process can be simplified and easily completed when assembling the massage device.

[0118] According to the swing adjustment part of the leg massage part connecting device of this utility model, by realizing various movements such as the user's legs opening together and rotating together in one direction and rotating together in the other direction, the massage device can provide various stretching modes, etc.

[0119] Figure 5 This is a perspective view of the leg angle adjustment part according to an embodiment of the present invention. Figure 6 It is shown Figure 5 A perspective view of a portion of the housing cut open from the gearbox of the leg angle adjustment section.

[0120] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 According to one embodiment of the present disclosure, the leg angle adjustment unit 3500 is configured to cause the leg massage unit 2000 to rotate in the up-down direction.

[0121] The leg angle adjustment unit 3500 includes at least one of the following: an angle adjustment unit frame 3600, a leg rotation motor 3732, and a leg support unit 3800. The leg rotation motor 3732 may be provided in the form of a gearbox 3700.

[0122] According to one embodiment of this disclosure, the angle adjustment frame 3600 can be fixed to the swing frame 3200 of the swing adjustment unit 3100. The angle adjustment frame 3600 can be positioned in a state where it is fixed and suspended below the lower surface 3204 of the swing frame 3200.

[0123] The angle adjustment frame 3600 can be formed from a plate and / or frame rods, and a gearbox configuration space 3670 can be formed therein. For example, the angle adjustment frame 3600 may include a plate forming an upper surface 3612 and a lower surface 3614, and a vertical frame rod 3616 disposed at the corner between the upper surface 3612 and the lower surface 3614. The space between the upper surface 3612 and the lower surface 3614 forms the gearbox configuration space 3670. However, the present invention is not limited to the structure of the angle adjustment frame described above.

[0124] A leg rotation motor 3732 is provided in the angle adjustment frame 3600 to provide driving force for the leg massage unit 2000 to rotate in the up and down direction.

[0125] According to one embodiment of the present disclosure, the leg rotation motor 3732 is modularized into a gearbox 3700 and configured in a modular form in the angle adjustment frame 3600.

[0126] The gearbox 3700 includes a housing 3710, a leg rotation motor 3732, and a gear section, the gear section being provided with a plurality of gears that drive the angle adjustment rotation shaft 3760 by slowing down the rotation of the leg rotation motor 3732.

[0127] The housing 3710 houses the leg rotation motor 3732, the first gear section 3730, the second gear section 3740, and the third gear section 3750.

[0128] The first gear portion 3730 includes a first worm gear 3734 connected to the motor shaft of the leg rotation motor 3732. The first gear portion 3730 is configured to extend upward toward the leg rotation motor 3732.

[0129] The portion of the housing 3710 that houses the leg rotation motor 3732 and the first gear portion 3730 forms the first housing portion 3713.

[0130] The second gear section 3740 includes a worm wheel 3742 that meshes with the first worm 3734 and a second worm 3744 coaxially coupled to the worm wheel 3742. In the gearbox configuration space 3670, the second gear section 3740 is configured to intersect with the first gear section 3730 and extend in the front-rear direction.

[0131] The worm gear 3742 and the second worm 3744 form a reduction ratio to reduce the rotational speed transmitted to the worm gear 3742 and output it to the output gear 3752.

[0132] The portion of the housing 3710 that houses the second gear portion 3740 forms the second housing portion 3714.

[0133] The third gear section 3750 includes an output gear 3752 that meshes with the second worm gear 3744. The output gear 3752 is connected to the angle adjustment rotating shaft 3760. The third gear section 3750 is disposed in the gearbox configuration space 3670 in front of the first gear section 3730 and the leg rotary motor 3732, and is configured to extend in the left-right direction.

[0134] The portion of housing 3710 that houses the third gear 3750 forms the third housing portion 3715. The angle adjustment rotation shaft 3760 extends outward through the housing 3710, that is, through the third housing portion 3715.

[0135] The gearbox 3700 can convert the rotation of the leg rotation motor 3732 into the high torque required for the rotation of the leg massage unit 2000.

[0136] Within the gearbox mounting space 3670, the upper and lower ends of the first housing portion 3713 are fixed to the angle adjustment frame 3600. Specifically, the upper end of the first housing portion 3713 is fixed to the upper surface 3612 of the angle adjustment frame, and the lower end is fixed to the lower surface 3614 of the angle adjustment frame. Furthermore, a pair of clamps 3620 are fixed on the lower surface 3614 of the angle adjustment frame 3600 to support both ends of the angle adjustment rotating shaft 3760, enabling it to rotate. As described above, the gearbox 3700 can be easily assembled with the angle adjustment frame 3600.

[0137] According to one embodiment of the gearbox 3700 of this disclosure, the leg rotation motor and gears can be compactly arranged within the gearbox configuration space 3670 within the angle adjustment unit frame 3600. The leg angle adjustment unit 3500 can be modularized and assembled into the massage device as a single component assembled in a modular form.

[0138] The rotation of the leg rotation motor 3732 is controlled by a control unit, and the forward and reverse rotation of the leg rotation motor 3732 causes the leg support unit 3800 to rotate up and down. To accurately control the rotation of the leg rotation motor 3732 and to sense the rotation of the leg rotation motor 3732, sensors such as encoders can be installed. This allows adjustment of the angle of the leg massage unit 2000.

[0139] The leg support 3800 includes an angle adjustment bracket 3810 and a moving wheel 3820, which are fixed to the connecting end of the angle adjustment rotation shaft 3760.

[0140] The angle adjustment bracket 3810 branches off from one side to both sides to form connecting ends that are fixed to the angle adjustment rotation shaft 3760 on both sides. The other end of the angle adjustment bracket 3810 is connected to a movable wheel 3820 that contacts the back of the leg massage unit 2000.

[0141] When the leg support 3800 rotates upwards due to the rotation of the leg rotation motor 3732, the leg support 3800 pushes upwards and lifts the back of the leg massage unit 2000, causing the leg massage unit 2000 to rotate upwards around the leg massage rotation axis. When the leg rotation motor 3732 rotates in the opposite direction to cause the leg support 3800 to rotate downwards, the leg massage unit 2000 rotates downwards under load while supported by the leg support 3800.

[0142] Figure 7 The image shows a state in which the leg massage unit is rotated upward (i.e., lifted) by the leg angle adjustment unit in a massage device according to an embodiment of the present invention.

[0143] According to one embodiment of the present invention, the leg angle adjustment part 3500 can be configured as a modular leg angle adjustment part 3500 supported on the main frame 1100 (e.g., seat frame 1250). The mechanical connection of the leg angle adjustment part 3500 can be completed simply by assembling the angle adjustment part frame 3600 fixed in front of the seat frame 1250.

[0144] When the rotation angle of the leg massage unit 2000 is adjusted in the vertical direction by rotating the leg support 3800, interference with other components disposed within the seat frame 1250 and / or base frame 1300 is minimized or does not occur. Therefore, as Figure 7 As shown, the leg massage unit 2000 can have an increased range of angle adjustment.

[0145] Furthermore, since the output of the leg rotation motor 3732 can make the angular velocity of the leg massage unit 2000 greater than that of the actuator, the movement of the leg massage unit 2000 of the massage device can be controlled more quickly.

[0146] In known massage devices, a retractable actuator is arranged in the base frame or seat frame, and the leg massage unit 2000 is rotated by the extension and retraction of the actuator, thereby performing angle adjustment of the leg massage unit. To increase the rotation angle of the leg massage unit 2000, an actuator with a long extension length is required, as well as an actuator that prevents interference with other components within the base frame or seat frame. Due to spatial constraints for accommodating the actuator and interference between the actuator and the seat frame and / or the base frame, there are limitations in increasing the rotation angle of the leg massage unit. For example, in known configurations where the actuator extends, it is not easy to rotate the leg massage unit 2000 upwards. Figure 7 The degree indicated.

[0147] On the other hand, in recent years, massage devices have been evolving to incorporate various functions, thus making it difficult to find sufficient space within the base frame or seat frame to house components that perform these functions. However, as with this invention, when the leg angle adjustment unit is positioned outside the main frame, space can be ensured within the base frame or seat frame for assembling other components.

[0148] According to another embodiment of the present disclosure, the connecting device for the leg massager can include a leg angle adjustment unit 3500 without the need for a swing adjustment unit 3100.

[0149] The angle adjustment frame 3600 can be directly connected to the seat frame 1250, or fixed to a seat frame extension extending from the seat frame 1250. For example, the swing adjustment unit described in conjunction with an embodiment of the present invention can correspond to the seat frame extension.

[0150] According to another embodiment of this disclosure, a leg angle adjustment part 3500 may be provided for an integrated leg massage part 2000 formed by integrally combining one leg massage part 2001 and the other leg massage part 2002. The leg angle adjustment part 3500 is provided for the integrated leg massage part 2000, and the leg support part 3800 pushes and lifts the back of the integrated leg massage part 2000 so that the integrated leg massage part 2000 can rotate upward.

[0151] Furthermore, a leg angle adjustment unit 3500 is provided for the leg massage unit 2000, which can operate independently for one leg massage unit 2001 and the other leg massage unit 2002. In this case, a leg angle adjustment unit 3500 for one leg massage unit 2001 and a leg angle adjustment unit 3500 for the other leg massage unit 2002 are provided, and the vertical rotation angle of one leg massage unit 2001 and the other leg massage unit 2002 can be adjusted independently.

[0152] Figures 8A to 8C This is a diagram illustrating the operation of the leg massage section of the leg massage section connecting device according to the present invention.

[0153] Figure 8A The initial position of the leg massage unit 2000 in the massage device is shown. One leg massage unit 2001 and the other leg massage unit 2002 are connected in a manner that allows them to operate independently, and a leg massage unit connecting device 3000 is provided, which is provided with a swing adjustment unit 3100 and a leg angle adjustment unit 3500 corresponding to the one leg massage unit 2001 and the other leg massage unit 2002, respectively.

[0154] Figure 8B The illustration shows that one leg massage unit 2001 and the other leg massage unit 2002 are adjusted from their initial positions to rotate upwards, i.e., adjusted to a raised state, and both leg massage units 2001 and 2002 swing and rotate outwards in a spaced-apart direction. This movement of the leg massage units 2001 and 2002 simultaneously raises the user's leg and opens both legs. At this time, the upward and outward rotation angles of the leg massage units 2001 and 2002 can be different.

[0155] Figure 8C The diagram shows a leg massage unit 2001 on one side and a leg massage unit 2002 on the other side swinging and rotating to one side. The leg massage units 2001 and 2002 can perform a leg swinging motion pattern that repeatedly moves to one side and to the other side. At this time, the leg massage units 2001 and 2002 can perform the swinging motion while raised upwards.

[0156] like Figures 8A to 8C As shown, in the massage device according to the present invention, the leg massage part can realize various movements, therefore, the massage device can provide various stretching modes and massage modes.
