[0103] The rack gear (1211) may be provided in a facing manner on the body frame (1200). The massage module may move along the rack gear (1211). For example, the massage module may include a gear that meshes with the rack gear (1211), and the massage module may move upward or downward by rotating the gear by an actuator provided in the massage module.

[0104] The rack gear (1211) may be made of a metal material or a plastic material. For example, the rack gear (1211) may be made of, but is not limited to, iron, steel, an alloy, reinforced plastic, melamine resin, phenol resin, etc.

[0105] According to one embodiment of the present disclosure, the seat frame (1250) and the back frame (1210) are formed as separate frames, and their respective ends can be arranged adjacent to each other. Since the seat frame (1250) and the back frame (1210) are formed as separate frames and are movably coupled to each other, the angle between the seat frame (1250) and the back frame (1210) can be easily adjusted. The movement of the back frame (1210) corresponds to the movement of the back portion (1000a), and the movement of the seat frame (1250) corresponds to the movement of the seat portion (1000b).

[0106] The back frame (1210) forms the skeleton of the back (1000a) and may include a rack gear support frame (1220) extending in the longitudinal direction while supporting the rack gear (1211).

[0107] The seat frame (1250) supports the back frame (1210) and is placed on top of the base frame (1300). The seat frame (1250) forms the skeleton of the seat portion (1000b), which is the part where the user sits. The seat frame (1250) is installed by being connected to the back frame (1210).

[0108] The back frame (1210) can be rotatably connected to the base frame (1300) and / or the seat frame (1250). The back frame (1210) can be converted to allow the massage device (100) to implement a sitting position and a lying position.

[0109] Additionally, the seat frame (1250) can be rotatably connected to the base frame (1300) and / or the back frame (1210). Accordingly, the angle between the back frame (1210) and the seat frame (1250) can be adjusted when the massage device (100) switches between sitting mode and reclining mode.

[0110] The arm massage unit (3000) is positioned on the side of the body massage unit (1000).

[0113] Hereinafter, the terms arm massage unit (3000), support unit (3200), and arm massage provider unit (3100) will be used representatively to describe the configuration, except when it is necessary to explain the first arm massage unit (3000a) and the second arm massage unit (3000b) separately.

[0114] FIG. 5 is a drawing showing the connection relationship of actuators for adjusting the seat angle, back angle, and leg angle in a massage device according to one embodiment of the present invention.

[0115] The seat angle can be defined as the angle that the seat frame makes with respect to the ground, the back angle can be defined as the angle that the back frame makes with respect to the ground, and the leg angle can be defined as the angle that the leg massage part makes with respect to the ground.

[0116] Figures 5 (a), (b), and (c) show a seat angle actuator, an isometric angle actuator, and a leg angle actuator, respectively.

[0117] A massage device (100) according to one embodiment of the present disclosure includes a plurality of actuators to provide various massage modes and / or stretching modes.

[0118] A massage device (100) according to one embodiment of the present disclosure may include a sliding actuator (1610) for controlling sliding of the massage device (100) (see FIG. 3).

[0119] A sliding actuator (1610) is installed between the base frame (1300) and the floor base frame (1380) to control the forward and backward movement of the body massage part. One end of the sliding actuator (1610) is connected to the base frame (1300), and the other end is connected to the floor base frame (1380).

[0120] A massage device (100) according to one embodiment of the present disclosure may include a seat angle actuator (1620) to adjust the angle of the seat portion (1000b).

[0121] Referring to (a) of FIG. 5, a seat angle actuator (1620) can be connected between a base frame (1300) and a seat frame (1250). One end of the seat angle actuator (1620) is connected to the base frame (1300), and the other end is connected to the seat frame (1250). The seat angle actuator (1620) can adjust the angle at which the seat frame (1250) and the seat portion (1000b) supported by the seat frame (1250) are tilted by moving the seat frame (1250) in a forward and backward direction with respect to the base frame (1300).

[0122] A massage device (100) according to one embodiment of the present disclosure may include an isometric actuator (1630) to adjust the angle of the back (1000a).

[0123] Referring to (b) of FIG. 5, a conformal angle actuator (1630) can be connected between a seat frame (1250) and a back frame (1210). One end of the conformal angle actuator (1630) is connected to the seat frame (1250), and the other end is connected to the back frame (1210). The conformal angle actuator (1630) can adjust the angle of the back frame (1210) and the back portion (1000a) supported by the back frame (121) by moving the back frame (1210) in the forward and backward direction with respect to the seat frame (1250).

[0124] A massage device (100) according to one embodiment of the present disclosure may include a leg angle actuator (1640) to adjust the angle of a leg massage unit (2000).

[0125] Referring to (c) of FIG. 5, a leg angle actuator (1640) may be provided between the seat frame (1250) and the leg massage unit (2000).

[0126] One end of the leg angle actuator (1640) is connected to the seat frame (1250), and the other end is connected to the leg angle adjustment unit (2110). The leg angle adjustment unit (2110) may have a top end hingedly connected to the base frame (1300) and a wheel at the other end that contacts the rear of the leg massage unit (2000).

[0127] When the leg angle actuator (1640) extends, the leg angle adjustment unit (2110) rotates upward around the hinge connection, and the wheel at the other end pushes up the leg massage unit (2000). When the leg angle actuator (1640) contracts, the leg angle adjustment unit (2110) rotates downward, and the leg massage unit (2000) descends while in contact with the leg angle adjustment unit (2110). In this way, the leg angle actuator (1640) moves the leg angle adjustment unit (2110) to rotate the leg massage unit (2000) in the up-and-down direction, thereby adjusting the angle of the Dara massage unit (2000).

[0128] The massage device according to the present invention does not exclude that one end of the leg angle actuator (1640) is connected to the base frame (1300). However, in the case where the leg angle actuator (1640) is provided between the seat frame (1250) and the leg angle adjustment unit (2110) according to one embodiment of the present disclosure, the angle of the leg massage unit (2000) is adjusted by adding the adjusted angle of the seat frame (1250) and the angle adjusted by the actuation of the leg angle adjustment unit (2110), so that it is easy to increase the angle at which the leg massage unit (2000) is lifted when the posture is changed to the reclining mode.

[0129] In an embodiment in which the leg massage unit (2000) includes a first leg massage unit (2000a) and a second leg massage unit (2000b) that are physically separated and operate independently, a leg angle actuator (1640) is provided for each of the first leg massage unit (2000a) and the second leg massage unit (2000b) and is individually controlled.

[0130] According to one embodiment of the present disclosure, each actuator, including a sliding actuator (1610), a seat angle actuator (1620), a conformal angle actuator (1630), and a leg angle actuator (1640), is controlled by a control unit (300). For example, the control unit (300) can control the sliding, seat angle, conformal angle, and leg angle of the massage device by controlling the actuators.

[0131] According to one embodiment of the present disclosure, each actuator is provided with an encoder capable of detecting the number of rotations and speed of the motor, so that the extension / contraction length, speed, etc. of the actuator can be controlled by the control unit (300) to suit various modes of the massage device (100) and the user's body.

[0132] FIG. 6 is a drawing showing an example of posture change of a massage device according to the present invention.

[0133] According to one embodiment of the present invention, the massage device (100) can be posture-converted to implement a sitting mode (left) and a reclining mode (right).

[0134] A massage device (100) according to one embodiment of the present disclosure can individually adjust the seat angle, back angle, and leg angle to set angles to perform a specific massage mode and a specific stretching mode.

[0135] For example, the massage device (100) can slide forward. Before the massage device (100) changes its posture to the reclining mode, the massage device (100) can slide forward to prevent the massage device (100) from colliding with a structure at the rear.

[0136] Additionally, the massage device (100) can perform movements in which the seat angle, back angle, and leg angle are adjusted simultaneously, sequentially, or with a time delay to perform a specific stretching mode.

[0137] According to one embodiment of the present disclosure, when the massage device (100) changes its posture from a sitting mode to a reclining mode, the back frame (1210) supports the back (1000a) and is laid down toward the ground, the seat frame (1250) supports the seat (1000b) and is lifted relative to the ground, and the leg massage unit (2000) is lifted relative to the ground.

[0138] Additionally, in the arm massage unit (3000), the arm massage providing unit (3100) moves in an inclined direction backward with respect to the support unit (3200).

[0139] In the present disclosure, the direction forward or backward is based on the direction shown in Fig. 6.

[0140] FIG. 7 is a drawing showing the structure and operation for independent movement of an arm massage unit of a massage device according to one embodiment of the present invention, FIG. 8 is a drawing showing the inner side of an arm massage providing unit, FIG. 9 is a partially exploded perspective view of the arm massage unit shown in FIG. 7, and FIG. 10 is a component drawing of an arm massage unit driving module.

[0141] The arm massage unit (3000) is provided on the side of the body massage unit (1000). The arm massage unit (3000) is provided to fix the user's arm and / or provide a massage.

[0142] The arm massage unit (3000) includes a support unit (3200), an arm massage providing unit (3100), and an arm massage unit driving module (3300).

[0143] The arm massage provision unit (3100) is positioned on the upper side of the support unit (3200) and is movably supported.

[0144] The arm massage unit drive module (3300) provides a moving force that enables the arm massage provider (3100) to move independently with respect to the support unit (3200).

[0145] Referring to FIG. 6, the position of the arm massage provider (3100) in the sitting mode (left) of the massage device (100) is referred to as the first position, and the position of the arm massage provider (3100) in the reclining mode (right) of the massage device (100) is referred to as the second position. The second position is a position in which the arm massage provider (3100) is inclined so that the position of the arm massage provider (3100) is lowered while moving rearward compared to the first position. In this way, the arm massage provider (3100) can be inclined downwardly moved from the first position to the second position with respect to the support member (3200).

[0146] An arm receiving groove (3110) is formed in the arm massage providing unit (3100) for inserting the user's arm (see FIG. 8). An air cell (3112) is provided in the arm receiving groove (3110) for fixing the user's arm. The arm receiving groove (3110) is formed as a 'ㄷ' shaped groove that opens toward the inner side (3130) of the arm massage providing unit (3100). The air cell (3112) can be inflated by the air supply unit to fix the user's arm or provide a massage by repeatedly expanding and contracting.

[0147] An interference prevention groove (3101) may be formed on the rear side of the inner surface (3103) of the arm massage provision unit (3100). The interference prevention groove (3101) is formed to prevent interference between the arm massage provision unit (3100) and the back (1000a) when the massage device (100) switches to a reclining mode and the back (1000a) is laid down and / or when the arm massage provision unit (3100) moves with respect to the support unit (3200).

[0148] The support member (3200) can be fixed to the side of the base frame (1300).

[0149] The upper surface (3210) of the support portion (3200) is formed as a downwardly inclined surface that slopes downward toward the rear, and the lower surface (3107) of the arm massage provider portion (3100) is formed to be inclined corresponding to the downwardly inclined upper surface (3210). The arm massage provider portion (3100) moves inclined along the downwardly inclined upper surface (3210) of the support portion.

[0150] The arm massage unit drive module (3300) movably supports the arm massage provider (3100) relative to the support unit (3200) and provides moving force.

[0151] The arm massage unit drive module (3300) may include at least some or all of the arm massage unit actuator (3320), the support plate (3310), the guide rail (3330), and the guide block (3340).

[0152] According to the present disclosure, an arm massage actuator (3320) is connected to a support member (3200) at one end and to an arm massage provider (3100) at the other end. As the arm massage provider actuator (3320) expands, the arm massage provider (3100) can move relative to the support member (3200). The arm massage provider actuator (3320) provides a moving force that directly moves the arm massage provider (3100) relative to the support member (3200).

[0153] In order for the movement of the arm massage provider (3100) to be performed along a movement path parallel to the stretching direction of the arm massage provider actuator (3320), the arm massage provider actuator (3320) may be connected parallel to the movement direction of the arm massage provider (3100), for example, the inclined movement direction.

[0154] According to one embodiment of the present disclosure, the arm massage actuator (3320) is disposed inside the arm massage providing unit (3100).

[0155] The arm massage actuator (3320) is disposed inside one of the arm massage provider (3100) and the supporter (3200), and is connected to the other of the arm massage provider (3100) and the supporter (3200) via the support plate (3310). Through this, the arm massage actuator (3320) can be connected to both the arm massage provider (3100) and the supporter (3200).

[0156] The support plate (3310) supports the movement of the arm massage providing unit (3100) relative to the support unit (3200) by physically connecting an arm massage providing unit actuator (3320) disposed inside one of the arm massage providing unit (3100) and the support unit (3200) to the other of the arm massage providing unit (3100) and the support unit (3200) that are positioned apart from each other.

[0157] According to one embodiment of the present disclosure, the support plate (3310) may include a lower portion (3311) fixed to the support portion (3200), and an upper portion (3312) extending upward from the lower portion (3311) and positioned inside the arm massage providing portion (3100).

[0158] The arm massage actuator (3320) is positioned adjacent to the lower surface (3107) inside the arm massage providing unit (3100) and has one side connected to the support plate (3310). The other side of the arm massage actuator (3320) is connected to the arm massage providing unit (3100).

[0159] According to one embodiment of the present disclosure, the lower portion (3311) of the support plate (3310) is illustrated as being fixed to the interior of the support member (3200), but is not limited thereto. For example, it may be a portion fixed to the upper surface (3210) of the support member (3200).

[0160] The support plate (3310) extends through the second through hole (3212) formed on the upper surface (3210) of the support portion (3200) and the first through hole (3107a) formed on the lower surface (3107) of the arm massage provider (3100). The first through hole (3107a) formed on the lower surface (3107) of the arm massage provider (3100) forms a path along which the arm massage provider (3100) moves relative to the support plate (3310), and thus extends in the longitudinal direction with a sufficient length so that the support plate (3310) does not interfere with the arm massage provider (3100).

[0161] According to one embodiment of the present disclosure, the lower part (3311) of the support plate (3310) can be extended and fixed into the interior of the support part (3200). The lower frame (3204) is fixed to the body of the support part (3200), i.e., the lower body (3202) formed as an injection molded material, and the lower part (3311) of the support plate (3310) is fixed to the lower frame (3204). This configuration can help assemble the arm massage part (3000), including assembling the support plate (3310), and the support plate (3310) to support the load of the arm massage providing part (3100).

[0162] The upper portion (3312) of the support plate (3310) can be supported to be relatively movable on the arm massage provider (3100). According to one embodiment of the present disclosure, the support plate (3310) can be supported to be relatively movable on the arm massage provider (3100), specifically, the guide rail (3330).

[0163] One end of the arm massage actuator (3320) can be fixed to the support plate (3310). A first bracket (3315) to which one end of the arm massage actuator (3320) is connected is provided on one side of the upper portion (3312) of the support plate (3310).

[0164] The arm massage actuator (3320) is extended and arranged at an angle parallel to the movement path of the arm massage provider (3100), and the other end of the arm massage provider actuator (3320) is fixed to the arm massage provider (3100). The arm massage provider (3100) has an upper frame (3104) fixed to a body formed of an injection molded material, i.e., an upper body (3102), and the other end of the arm massage provider actuator (3320) is fixed to the upper frame (3104). The upper frame (3104) is provided with a second bracket (3105) to which the other end of the arm massage provider actuator (3320) is connected.

[0165] When the arm massage actuator (3320) operates, the load (3323) is withdrawn, and the arm massage actuator (3320) extends with respect to the support plate (3310) to which one end is fixed, and the other end of the arm massage actuator (3320) fixed to the second bracket (3105) pulls the arm massage provider (3100). This provides a moving force for the arm massage provider (3000) to tilt. Accordingly, the arm massage provider (3100) can tilt along the extension direction of the arm massage provider actuator (3320). Since the support plate (3310) is fixed to the support portion (3200), the arm massage provider (3100) moves with respect to the support portion (3200).

[0166] According to one embodiment of the present disclosure, a guide rail (3330) is disposed on an arm massage providing unit (3100) and is connected to one side of an arm massage providing unit actuator (3320) so as to be relatively movable. The guide rail (3330) guides the relative movement of the arm massage providing unit (3100) with respect to the support unit (3200).

[0167] The guide rail (3330) is extended and fixed adjacent to the first through hole (3107a) of the lower surface (3107) inside the arm massage providing unit (3100). The guide rail (3330) is arranged parallel to the extension direction of the arm massage providing unit actuator (3320) and the movement direction of the arm massage providing unit (3100).

[0168] The second bracket (3105) to which the other end of the arm massage actuator (3320) is coupled is positioned at the rear side of the guide rail (3330) and spaced apart from the guide rail (3330).

[0169] Since one side of the arm massage actuator is connected to the guide rail (3330) so as to be relatively movable, for example, when the arm massage actuator (3320) extends, the other side of the arm massage actuator (3320) moves in a direction in which the length increases with respect to one side, and the arm massage providing unit (3100) moves together with the guide rail (3330) with respect to one side of the arm massage actuator (3320).

[0170] According to one embodiment of the present disclosure, one side of the arm massage actuator (3320) is connected to the guide rail (3330) via the support plate (3310). However, the present invention is not limited thereto, and for example, the support plate (3310) may be fixed to a body located on one side of the arm massage actuator (3320), and the other end of the arm massage actuator (3320) may be directly connected to the guide rail (3330) so as to be relatively movable.

[0171] Referring to the drawing, an embodiment is described in which one side of the arm massage actuator (3320) is connected to a guide rail (3330) via a support plate (3310).

[0172] One side of the arm massage actuator (3320) is placed on one surface of the upper part (3312) of the support plate (3310), and one end is connected by the first bracket (3315). The guide rail (3330) is placed on the other surface of the support plate (3310).

[0173] A guide block (3340) is coupled to the other surface of the support plate (3310) facing the guide rail (3330).

[0174] A guide block (3340) coupled to a support plate (3310) guides the movement of a guide rail (3330). To this end, the guide block (3340) is fitted such that the guide rail (3330) can move relative to it. Accordingly, the guide rail (3330) can move while being supported by the guide block (3340).

[0175] The guide block (3340) is formed to be fitted into the rail projections (3331) protruding from the upper and lower portions of the guide rail (3330) toward the support plate (3310). The guide block (3340) is formed by the upper guide block and the lower guide block forming one guide block unit.

[0176] The guide block (3340) can be formed in a form in which an upper guide block and a lower guide block are connected to be fitted to the upper and lower parts of the guide rail (3330), in which case one guide block (3340) forms one guide block unit.

[0177] When the guide blocks are formed separately to form upper and lower guide blocks, it is advantageous to place the guide blocks (3340) according to the design of the guide rail (3330) and assembly is easy. The guide blocks (3340) can be fixed to the other surface of the support plate (3310) with a fastening member.

[0178] According to one embodiment of the present disclosure, one or more guide block units are arranged on a guide rail and spaced apart from each other along the length of the guide rail.

[0179] Referring to Fig. 10, it can be seen that four guide blocks (3340) form two guide block units and are spaced apart along the length direction of the guide rail (3330). When at least two guide block units are provided, it can be advantageous in preventing shaking by maintaining the support plate (3310) and the guide rail (3330) parallel to each other even when a lateral load is applied to the arm massage provider (3100).

[0180] In addition, since the guide block (3340) is fitted into the guide rail (3330), the arm massage providing unit (3100) to which the guide rail (3330) is coupled can be stably supported by the support plate (3310) and the support unit (3200) to which the support plate (3310) is fixed.

[0181] According to one embodiment of the present disclosure, when the arm massage actuator (3320) is extended by the motor driving the load (3323) in the arm massage actuator (3320), the guide rail (3330) moves while supporting the arm massage provider (3100). The guide rail (3330) moves while being supported by the guide block (3340) of the support plate (3310). That is, when the arm massage actuator (3320) is extended, the guide rail (3330) moves, guiding the movement of the arm massage provider (3100).

[0182] The arm massage actuator (3320) is controlled by the control unit (300). In addition, the arm massage actuator (3320) may be equipped with an encoder that detects the rotation of the motor. Accordingly, the control unit (300) can detect and control the extension and contraction length, speed, etc. of the arm massage actuator (3320).

[0183] The movement of the arm massage provider (3100) is determined by the extension direction of the arm massage provider actuator (3320) and the extension direction of the guide rail (3330), and the arm massage provider (3100) can be supported by the connection between the guide rail (3330) and the support plate (3310). Since the support plate (3310) supports the load of the arm massage provider (3100), the load can be distributed even when the support member (3200) does not directly contact the arm massage provider (3100), or even when it does directly contact the arm massage provider (3100). Accordingly, the load of the arm massage provider (3100) is fully applied between the upper surface (3210) of the support member (3200) and the lower surface (3107) of the arm massage provider (3100), and noise and appearance damage can be minimized compared to a case where the movement is guided by direct contact.

[0184] The arm massage unit (3000) according to the present invention includes a first arm massage unit (3000a) arranged on one side of the body massage unit and a second arm massage unit (3000b) arranged on the other side of the body massage unit (see FIG. 3).

[0185] The movement of the first arm massage providing unit (3100a) relative to the first support unit (3200a) in the first arm massage unit (3000a) and the movement of the second arm massage providing unit (3100b) relative to the second support unit (3200b) in the second arm massage unit (3000b) are performed by arm massage unit drive modules, e.g., arm massage unit actuators, provided in each of the first arm massage unit (3000a) and the second arm massage unit (3000b), and thus move independently of each other. Accordingly, the first arm massage providing unit (3100a) and the second arm massage providing unit (3100b) can move in opposite movement directions or move at different movement distances to perform specific operations in the stretching mode or the massage mode.

[0186] The independent behavior, i.e., movement control, of the arm massage providing unit (3100) according to the present invention enables the performance of various massage modes or stretching modes.

[0187] The movement of the arm massage providing unit (3100) with respect to the support unit (3200) is individually performed by an arm massage providing unit drive module (3300), for example, an arm massage providing unit actuator (3320), which movably connects the support unit (3200) and the arm massage providing unit (3100). In addition, the arm massage providing unit (3100) is not mechanically connected to the back unit (1000a), the seat unit (1000b), and the leg massage providing unit (2000) because its movement is restricted. For example, the arm massage providing unit (3100) may be formed so as to be movably connected to the support unit (3200) and not directly connected to the back unit (1000a), the seat unit (1000b), and the leg massage providing unit (2000). Accordingly, the movement of the arm massage providing unit (3100) in the arm massage unit (3000) can be performed individually, regardless of the angle adjustment of the back (1000a) by the isometric actuator (1630), i.e., isometric angle adjustment, the angle adjustment of the seat unit (1000b) by the seat angle actuator (1620), i.e., seat angle adjustment, and the leg angle adjustment by the leg angle actuator (1640).

[0188] Accordingly, as an example of an action in the stretching mode, the air cell (3112) of the arm receiving groove (3110) can expand to secure the user's arm. In this state, when the back (1000a) rotates backward and downward while changing the posture to the reclining mode, the user's arm can remain fixed in the arm receiving groove (3110). As a result, the user's back is separated from the back (1000a) and the arm is pulled. This enables an arm stretching action.

[0189] After the arm stretching motion has been performed for a predetermined period of time, the arm massage provider (3100) moves backward and downward with respect to the support provider (3200), i.e., the arm massage provider (3100) moves from the first position to the second position, so that the user's back can be leaned against the back portion (1000a) again. In the reclining mode of the back portion (1000a), the user's shoulders are lowered, so that the user's arms move to a lower position in addition to the backward movement, resulting in an overall comfortable position.

[0190] According to the present invention, the arm massage actuator (3320) moves independently without being mechanically constrained by leg angle adjustment, back seat angle, and / or seat angle adjustment, so the above-described operation is possible.

[0191] In addition, according to one embodiment of the present disclosure, the movement of the arm massage providing unit (3100) with respect to the support unit (3200) can operate independently to implement various operation modes in conjunction with the length and angle adjustment movements of the first leg massage unit (2000a) and the second leg massage unit (2000b). For example, when implementing a walking mode in which the first leg massage unit (2000a) and the second leg massage unit (2000b) of the leg massage unit (2000) are adjusted in length to different degrees and the leg angles to different degrees, the first arm massage providing unit (3100a) and the second arm massage providing unit (3100b) can individually move in conjunction with the movements of the first leg massage unit (2000a) and the second leg massage unit (2000b) to implement an operation more suitable for the walking mode.

[0192] Fig. 11 is a drawing for explaining the sensor part of the arm massage part of the massage device according to the present invention.

[0193] According to one embodiment of the present disclosure, the arm massage providing unit (3100) of the arm massage unit (3000) may be provided with sensors (3401, 3402, 3403) to prevent safety accidents caused by the operation of the arm massage providing unit (3100) or another part of the massage device (100), such as the operation of the body massage unit (1000).

[0194] When the arm massage providing unit (3100) moves relative to the body massage providing unit (1000), a trapping accident may occur between the arm massage providing unit (3100) and the body massage providing unit (1000) and / or the support unit (3200). A trapping accident may occur when an object such as the user's body or clothing becomes trapped between the arm massage providing unit (3100) and another part.

[0195] Additionally, when the arm massage providing unit (3100) of the arm massage unit (3000) moves backward, a collision accident with the arm massage providing unit (3100) may occur.

[0196] To detect this, sensors are placed on at least one or all of the back (3106), the lower surface (3107), and the front surface (3108) of the arm massage provider (3100).

[0197] According to one embodiment of the present disclosure, the sensor may be an electrostatic sensor.

[0198] A first sensor (3401) is positioned on the inside of the upper body (3102) at the rear (3106) of the arm massage provider (3100). The first sensor (3401) may be formed as an electrostatic sensor as a contact detection sensor that detects contact with an object to prevent collision accidents.

[0199] The first sensor (3401) is extended in a folded form corresponding to the rib so as not to interfere with the rib for reinforcing the upper body (3102), and can be placed in contact with the rear surface (3106) of the arm massage providing unit (3100) on the inside of the upper body (3102). Despite the formation of the rib for reinforcing the arm massage providing unit (3100), it is possible for the first sensor (3401) to be placed in contact with the inner surface of the rear surface (3106).

[0200] The first sensor (3401) detects contact with an object at the rear (3106) of the arm massage providing unit (3100) to prevent accidents caused by collisions. When the arm massage providing unit (3100) moves downward relative to the support unit (3200), if an object is present in that area, the first sensor (3401) detects static electricity on the object, and the massage device (100) can stop operation and output a warning sound.

[0201] The second sensor (3402) is arranged to detect an object being caught between the inclined surface forming the lower surface (3107) on the rear side of the arm massage provider (3100) and the inclined surface forming the upper surface of the support portion (3200). The second sensor (3402) may be formed as an electrostatic sensor. The second sensor (3402) is arranged in contact with the lower surface (3107) on the inner side of the upper body (3102) of the arm massage provider (3100). The second sensor (3402) may be arranged on the rear part of the lower surface (3107) of the arm massage provider (3100). When the arm massage provider (3100) moves downwardly with respect to the support portion (3200), the sensor detects an object being caught between the inclined surface of the arm massage provider (3100) and the support portion (3200) along the movement path of the arm massage provider (3100). The second sensor (3402) may be extended in a folded form corresponding to the rib so as not to interfere with the rib for reinforcing the upper body (3102), similar to the first sensor (3401). Accordingly, even though the rib for reinforcing is formed on the lower surface (3107) of the arm massage provider (3100), it is possible for the second sensor (3402) to be placed in contact with the inner side of the lower surface (3107).

[0202] The third sensor (3403) is arranged to detect an object being caught between the inclined surface forming the lower surface (3107) on the front side of the arm massage provider (3100) and the inclined surface forming the upper surface of the support portion (3200). The third sensor (3403) may be formed as an electrostatic sensor. The third sensor (3403) is arranged in contact with the lower side of the front surface (3108) inside the upper body (3102) of the arm massage provider (3100). When the arm massage provider (3100) moves upwardly with respect to the support portion (3200), the third sensor detects an object being caught between the inclined surface of the arm massage provider (3100) and the support portion (3200) along the movement path of the arm massage provider (3100).

[0203] FIG. 12 is a drawing for explaining a joint between an arm massage unit and a body massage unit in a massage device according to the present invention, and FIG. 13 is a drawing for explaining a joint structure and assembly method of the joint unit illustrated in FIG. 12, wherein (a) of FIG. 12 illustrates a front joint unit, (b) of FIG. 12 illustrates a middle joint unit, and (c) of FIG. 12 illustrates a rear joint unit.

[0204] According to one embodiment of the present disclosure, the arm massage unit (3000) is positioned on the side of the body massage unit (1000) in such a way that the support unit (3200) is coupled to the side of the frame of the body massage unit (1000). The frame of the body massage unit (1000) may be a base frame (1300).

[0205] The joint between the support member (3200) and the body massage member (1000), for example, the base frame (1300), includes a front joint member (P1, P2), a middle joint member (P3), and a rear joint member (P4).

[0206] Referring to (a) of FIG. 12 and FIG. 13, the front joints (P1, P2) are formed on the front side of the base frame (1300).

[0207] The base frame (1300) has a connecting frame (1302) on the front side, and the connecting frame (1302) extends upward. The connecting frame (1302) can form a side of the frame of the body massage unit (1000).

[0208] First and second fasteners (1303, 1304) protrude from the front side of the frame of the body massage unit (1000), for example, the base frame (1300). The first fastener (1303) forms a front joint (P1) and is formed to protrude forward from the upper portion of the joint frame (1302). The second fastener (1304) forms a front joint (P2) and is formed to protrude forward and spaced apart from the lower side of the first fastener (1303).

[0209] On the inner surface (3203) of the support member (3200), fastening holes for bolt fastening are formed corresponding to the positions of the first and second fastening holes (1303, 1304). The bolts are fastened in a state where the first and second fastening holes (1303, 1034) and the fastening holes are aligned, and assembly of the front joints (P1, P2) is performed.

[0210] Since the front joint (P1, P2) is exposed to the outside from the front side of the massage device (100), bolt fastening can be easily performed.

[0211] Referring to (b) of FIG. 12 and FIG. 13, the intermediate joint (P3) can be formed in the middle side of the frame of the body massage unit (1000), for example, the base frame (1300).

[0212] A first insertion bracket (1310) is provided on a support axis frame (1320) formed on a side of a frame of a body massage unit (1000), for example, on a side middle portion of a base frame (1300), toward an inner surface (3203) of a support unit (3200). Correspondingly, a coupling protrusion (3205) protrudes from the middle portion of the inner surface (3203) of the support unit (3200).

[0213] The first insertion bracket (1310) provided on the support shaft frame (1320) has a first coupling groove (1311) with an open upper end. The opening of the first coupling groove (1311) is tapered so that the opening becomes wider as it goes toward the upper end. Both side surfaces of the first insertion bracket (1310) are bent toward the support shaft frame (1320) of the base frame (1300). As a result, the first insertion bracket (1310) is formed in a pocket shape in which the outer end of the coupling protrusion (3205) formed on the middle portion of the inner surface of the support portion (3200) is received therein.

[0214] The coupling protrusion (3205) is formed to protrude in the middle of the inner surface of the support member (3200) corresponding to the first insertion bracket (1310) and is inserted into the first coupling groove (1311).

[0215] The engaging projection (3205) forms a concave valley portion (3205a) at the portion that is fitted into the first engaging groove (1311). Therefore, when the engaging projection (3205) is placed in the opening of the first engaging groove (1311) of the first insertion bracket (1310), the engaging projection (3205) is guided to the first engaging groove (1311), and the valley portion (3205a) engages the inside of the first engaging groove (1311).

[0216] Referring to (c) of FIG. 12 and FIG. 13, the rear joint (P4) is formed adjacent to the intermediate joint (P3) and lower on the rear side than the intermediate joint (P3).

[0217] The rear joint (P4) is formed toward the rear from the middle of the inner surface (3203) of the base frame (1300) and the support (3200) of the body massage unit (1000), and is referred to as the rear joint (P4) because a tool is inserted from the rear of the massage device (100) to perform the final fixing.

[0218] The rear coupling portion (P4) includes a fastening member (1315) and a second insertion bracket (3206) to which the fastening member (1315) is coupled.

[0219] A rear fastening hole (1322) is formed on the lower rear side of the support axis frame (1320) of the frame of the body massage unit (1000), for example, the base frame (1300), and a fastening member (1315) is coupled to the rear fastening hole (1322).

[0220] The fastening member (1315) may include a fastening portion (1315a), an expanding portion (1315b), and a head (1315c). The fastening portion (1315a) is screw-fastened to the rear fastening hole (1322).

[0221] The fastening member (1315) has a first fastening depth in which the fastening portion (1315a) is loosely fastened to the rear fastening hole (1322), and a second fastening depth in which the fastening portion (1315a) is tightened to the rear fastening hole (1322).

[0222] A second insertion bracket (3206) protrudes from the middle of the inner surface (3203) of the support portion (3200) and below the rear side of the coupling protrusion (3205). The second insertion bracket (3206) protrudes so as to extend across the inner surface (3203) of the support portion (3200) and has a second coupling groove (3206a) into which a fastening member (1315) is inserted.

[0223] The second coupling groove (3206a) of the second insertion bracket (3206) is formed with a different opening direction compared to the first coupling groove (1311) of the first insertion bracket (1310). The first coupling groove (1311) of the first insertion bracket (1310) is opened upward, and the second coupling groove (3206a) of the second insertion bracket (3206) is opened downward.

[0224] The opening of the second coupling groove (3206a) of the second insertion bracket (3206) is formed so that the coupling portion (1315a) of the coupling member (1315) is guided toward the inside of the second coupling groove (3206a). The inner groove of the second coupling groove (3206a) is formed to correspond to the expanded portion (1315b) of the coupling member (1315).

[0225] When the fastening member (1315) is loosely assembled to the first fastening depth, the fastening portion (1315a) is inserted into the inner groove of the second coupling groove (3206a) of the second insertion bracket (3206) and is loosely assembled. Thereafter, when the fastening member (1315) is tightened to the second fastening depth, the expanded portion (1315b) of the fastening member (1315) can be firmly fixed by digging into the inner groove of the second coupling groove (3206a).

[0226] To this end, a chamfer may be formed between the expanding portion (1315b) and the fastening portion (1315a) of the fastening member (1315) so as to gradually increase in diameter. Accordingly, when the fastening member (1315) is tightened from a first fastening depth state in which it is loosely pre-assembled, it becomes a second fastening depth state, and the rear joint portion (P4) is firmly fastened and shaken can be prevented.

[0227] Below, the assembly method of the support part (3200) and base frame (1300) of the arm massage part (3000) is described.

[0228] In the massage device (100), the arm massage part (3000) is fixed to the side of the body massage part (1000). With the seat part (1000b) and the back part (1000a) assembled to the upper part of the base frame (1300), the support part (3200) can be fixed to the base frame (1300).

[0229] The P4 point, which is the rear joint, is covered by the support member (3200) and the body massage member (1000), making assembly difficult using a simple bolt fastening method. Visual confirmation of the fastening position is difficult, and alignment of the fastening position is not easy, which increases the difficulty of assembly.

[0230] According to one embodiment of the present disclosure, first, a fastening member (1315) is loosely pre-assembled into a rear fastening hole (1322) of a support shaft frame (1320) at point P4, which is a rear joint.

[0231] Afterwards, the fitting assembly of the first insertion bracket (1310) and the coupling protrusion (3205) at the intermediate joint point P3, and the fitting assembly of the second insertion bracket (3206) and the fastening member (1315) at the rear joint point P4 are performed.

[0232] At point P4, which is the rear joint, the joint position is aligned by fitting the joint member (1315) into the second joint groove (3206a) of the second insertion bracket (3206). Thereafter, fixation can be achieved at point P4 by tightening the joint member (1315) using a long tool from the rear of the massage device (100). At this time, the expanded portion (1315b) of the joint member (1315) can be firmly joined by being pressed into the second joint groove (3206a) of the second insertion bracket (3206).

[0233] Since the head (1315c) of the fastening member (1315) of the rear joint faces the rear of the massage device (100), assembly at the rear joint (P4) is completed with a simple tightening operation using a long tool.

[0234] Afterwards, bolts are fastened through the first and second fastening holes (1303, 1304) of the base frame (1300) at the front joint points P1 and P2 to fix the support part (3200) and the front part of the base frame (1300).

[0235] According to one embodiment of the present disclosure, the assembly of the second insertion bracket (3206) and the fastening member (1315) at the rear joint point P4 is performed while being guided by the fitting of the first insertion bracket (1310) and the fastening projection (3205) at the intermediate joint point P3, so that the setting of the fastening position at the rear joint point P4, i.e., the fitting of the fastening member (1315) and the second insertion bracket (3206), is relatively easy.

[0236] In addition, at point P4, which is a rear joint that is difficult to assemble, the load due to the support member (3200) is distributed rather than concentrated on the fastening member (1315), so that tightening of the fastening member (1315) is possible, and thus tightening using a tool can be performed relatively easily.

[0237] According to the embodiment of the present invention, the structure of the arm massage unit in which the arm massage providing unit moves incliningly with respect to the support unit in the combined structure of the base frame and the arm massage unit is not limited, and can also be applied to the arm massage unit in which the arm massage providing unit and the support unit are fixed with respect to each other.

[0238] Although the embodiments of the present disclosure have been described in more detail with reference to the attached drawings, the present disclosure is not necessarily limited to these embodiments, and various modifications may be implemented without departing from the technical spirit of the present disclosure. Therefore, the embodiments disclosed in the present disclosure are not intended to limit the technical spirit of the present disclosure, but to explain it, and the scope of the technical spirit of the present disclosure is not limited by these embodiments. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive. The protection scope of the present disclosure should be interpreted by the claims, and all technical ideas within a scope equivalent thereto should be interpreted as being included in the scope of rights of the present disclosure.
