The sensor bracket 1510 can be provided to support the sensor 1520. The sensor bracket 1510 can be coupled to a leg connection frame 1131b. For example, the sensor bracket 1510 can be welded to the leg connection frame 1131b or coupled by a separate fastening device. A method of coupling the sensor bracket 1510 to the leg connection frame 1131b can be replaced with various methods commonly used in the technical field to which the present invention belongs.
The sensor bracket 1510 may include a protrusion part 1511 and a curved part 1512. The protrusion part 1511 has one side which can be coupled to the leg connection frame 1131b and the other side which can protrude forward. The curved part 1512 can be curved downward from the protruding end of the protrusion part 1511. Therefore, the sensor bracket 1510 can be overall in a “L” shape. The curved part 1512 may have a sensor coupling hole 1512a.
The sensor 1520 can be coupled to the sensor bracket 1510. For example, the sensor 1520 can be coupled to the curved part 1512 of the sensor bracket 1510. In this case, at least a portion of the sensor 1520 can be configured to penetrate the sensor coupling hole 1512a of the sensor bracket. Therefore, at least a portion of the sensor 1520 can protrude forward from the curved part 1512.
The sensor 1520 can detect contact with the pressure plate 1540. For example, when an external force is applied to the pressure plate 1540 to rotate the pressure plate 1540, the pressure plate 1540 can come into contact with the sensor 1520. When the sensor 1520 comes into contact with the pressure plate 1540, the sensor 1520 can transmit the corresponding information to the control unit 1400. Upon receiving the information on the contact between the pressure plate 1540 and the sensor 1520, the control unit 1400 can control the operation of at least one of the first leg massage unit 1310 and the second leg massage unit 1330. Additionally, the control unit 1400 can activate the alarm unit to emit a warning signal to the user.

For example, the sensor 1520 may include a sensor housing 1521, a contact portion 1522 that is provided in the sensor housing 1521 to detect contact with the pressure plate 1540, a fastening portion 1523 for coupling to the sensor bracket 1510, and an electrode terminal 1524 for electrical connection to the external device.
The contact portion 1522 can slide inward in the sensor housing 1521 when pressure is applied by the pressure plate 1540. Accordingly, a separate elastic member that applies elastic force to the contact portion 1522 can be provided inside the sensor housing 1521. When the contact portion 1522 receives pressure and slides inward in the sensor housing 1521, the sensor 1520 can transmit a signal to the control unit 1400, so the control unit 1400 can control the operation of at least one of the first leg massage unit 1310 and the second leg massage unit 1330 or emit a warning signal to the user through the alarm unit.
The fastening portion 1523 can be provided for coupling with the sensor bracket 1510. The fastening portion 1523 can be made of a material with elastic force and can be inserted into the sensor coupling hole 1512a formed in the sensor bracket 1510 when the sensor 1520 is coupled. To facilitate insertion into the sensor coupling hole 1512a, the fastening portion 1523 may include inclined surfaces. The inclined surface can be configured such that the distance between the sensor housing 1521 and the sensor 1520 increases from the rear to the front while one end is fixed to the sensor housing 1521. Additionally, a flat surface can be provided on the other end of the inclined surface to facilitate contact with the sensor coupling hole 1521a. The flat surface can come into contact with the inner side of the sensor coupling hole 1521a. The fastening portion 1523 can be folded towards the sensor housing 1521 when gripped by the user. Therefore, when the sensor 1520 needs to be separated, the user can grip the fastening portion 1523 and detach the sensor 1520 from the sensor bracket 1510.
Meanwhile, the sensor 1520 can be replaced with various sensors commonly used in the technical field to which the present invention belongs, which can detect the rotation or contact of the pressure plate 1540. For example, the sensor 1520 can be equipped with at least one of a pressure sensor, an infrared sensor, an LED sensor, a touch sensor, or an electrode sensor.
The center support brackets 1530 can be arranged on both sides of the sensor bracket 1510. The center support bracket 1530 can be made separately from or integrally with the sensor bracket 1510. Alternatively, the center support bracket 1530 and the sensor bracket 1510 can be separately made and then combined using a method such as welding. The method of combining the center support bracket 1530 and the sensor bracket 1510 can be replaced with various methods commonly used in the technical field to which the present invention belongs. The center support bracket 1530 can be connected to the pressure plate 1540 in a rotatable manner. The sensor bracket 1510 may include a center fixing member 1531 and a center rotating member 1532.
The center fixing member 1531 can include, for example, a base part 1531c and side parts 1531d protruding upwards from both sides of the base part 1531c. The base part 1531c and side parts 1531d can be formed by a single member being bent. However, it is also possible to separately manufacture the base part 1531c and the side parts 1531d and combine them together.
The base part 1531c can form the lower surface of the center fixing member 1531. The base part 1531c may include at least one stopper 1531e. The stopper 1531e can restrict an angle at which the pressure plate 1540 rotates in the direction away from the sensor 1520. The stopper 1531e can protrude downward through the base part 1531c. When a single stopper 1531e is provided, the stopper can be positioned in the central area of the base part 1531c, and when multiple stoppers are provided, the stoppers may be arranged in at least one of the central area and both side area of the base part 1531c.
The positions and structures of the stoppers 1531e may be varied to limit the rotational angle of the pressure plate 1540. For example, it is also possible to mount the stopper 1531e to the lower surface of the base part 1531c and cause the entire stopper 1531e to protrude downward from the base part 1531c. Additionally, it is also possible to integrally manufacture the stopper 1531e with the base part 1531c. Furthermore, it is also possible to equip the stopper 1531e on the pressure plate 1540.
The side parts 1531d may include leg connection frame insertion grooves 1531d-1. The leg connection frame 1131b can be inserted and coupled to the leg connection frame insertion grooves 1531d-1. The leg connection frame insertion grooves 1531d-1 can be configured with one end of the side part 1531d facing the leg connection frame 1131b being cut off. The inner side of the leg connection frame insertion grooves 1531d-1 may have a shape matching the outer side of the leg connection frame 1131b. When the leg connection frame 1131b is inserted into the leg connection frame insertion grooves 1531d-1, the contacting portion between the side part 1531d and the leg connection frame 1131b can be welded. However, the method of combining the side part 1531d and the leg connection frame 1131b can be replaced with methods commonly used in the technical field to which the present invention belongs.
The side part 1531d can include a center rotating member insertion hole 1531d-2. The center rotating member 1532 can be hinge-coupled and rotatably coupled to the center rotating member insertion hole 1531d-2. The center rotating member insertion hole 1531d-2 can be provided at various positions on the upper portion of the side part 1531d to allow rotation of the center rotating member 1532.
The side part 1531d may include a pressure plate insertion hole 1531d-3. One side of the pressure plate insertion hole 1531d-3 can be hinge-coupled to allow rotation of the pressure plate 1540. The pressure plate insertion hole 1531d-3 can be provided at various positions on the side part 1531d to allow contact between the sensor 1520 and the pressure plate 1540 when the other side of the pressure plate 1540 rotates upward or downward (see
One of the side parts 1531d protruding from both sides of the base part 1531c may include a fixed piece 1531d-4 bent towards the other side part 1531d. However, it is also possible to separately manufacture fixed pieces 1531d-4 and combine the fixed pieces to both side parts 1531d. When the center rotating member 1532 rotates and contacts the fixed piece 1531d-4, the end of the center rotating member 1532 and the fixed piece 1531d-4 can be secured by a fastening member.
The side part 1531d may include a center bushing receiving groove 1531d-5. The center bushings 1311 and 1321 can be rotatably fitted into the center bushing receiving groove 1531d-5. The center bushing receiving groove 1531d-5 may, for example, be formed by cutting the upper end of the side part 1531d.
The center rotating member 1532 can be hinge-coupled to the side part 1531d to be rotatable. The center rotating member 1532 may include a center bushing fixing groove 1532d. When the center rotating member 1532 rotates and is secured to the fixed piece 1531d-4 of the side part 1531d, the center bushing fixing groove 1532d can support the center bushings 1311 and 1321 together with the center bushing receiving groove 1531d-5.
The pressure plate 1540 can be hinge-coupled to the center support bracket 1530 to be rotatable. The pressure plate 1540 may include an elastic member 1541. The elastic member 1541 can apply elastic force to the pressure plate 1540 to rotate the free end of the pressure plate 1540 away from the sensor 1520. The elastic member 1541 can be made of various materials that can provide elastic force to the pressure plate 1540. For example, the elastic member 1541 may be a torsion spring. When the elastic member 1541 is a torsion spring, both ends of the torsion spring can contact at least one of the pressure plate 1540 and the center support bracket 1530 when the pressure plate 1540 rotates.
The elastic member 1541 can prevent the pressure plate 1540 from rotating when the user's body or other objects are not caught between the leg massage unit 1300 and between the leg massage unit 1300 and the body massage unit 1100.
The pressure plate 1540 can rotate and come into contact with the sensor 1520. For example, when an external force greater than the elastic force of the elastic member 1541 is applied to the pressure plate 1540, the pressure plate 1540 can rotate and come into contact with the sensor 1520.

In addition, it is possible to prevent equipment malfunction and damage that may occur when objects other than the user's body are caught between the leg massage unit 1300 or between the leg massage unit 1300 and the body massage unit 1100.
Hereinafter, referring to
On one side facing the second leg massage unit 1330 of the first leg massage unit 1310, a light emitting sensor 1310a may be provided. On one side facing the first leg massage unit 1310 of the second leg massage unit 1330, a light receiving sensor 1330a that receives a signal transmitted from the light emitting sensor 1310a may be provided. It is also possible that a light emitting sensor is provided on the second leg massage unit 1330 and a light receiving sensor is provided on the first leg massage unit 1310. However, for the convenience of explanation, it is assumed that the first leg massage unit 1310 is equipped with a light emitting sensor 1310a and the second leg massage unit 1330 is equipped with a light receiving sensor 1330a in the following description.
When the first leg massage unit 1310 and the second leg massage unit 1330 are aligned, in other words, when the first leg massage unit 1310 and the second leg massage unit 1330 are arranged parallel in the width direction, a signal transmitted from the light emitting sensor 1310a can be received by the light receiving sensor 1330a.
When the signal from the light emitting sensor 1310a is received by the light receiving sensor 1330a, the control unit 1400 can determine that the first leg massage unit 1310 and the second leg massage unit 1330 are in an aligned state. If the signal from the light emitting sensor 1310a is not received by the light receiving sensor 1330a, the control unit 1400 can determine that the first leg massage unit 1310 and the second leg massage unit 1330 are not aligned and are in a crossed state.
The first leg massage unit 1310 and the second leg massage unit 1330 may have encoders. The encoder can measure at least one of the rotational speed (angular velocity) and the rotation amount of the first leg massage unit 1310 and the second leg massage unit 1330 and transmit the measured information to the control unit 1400.
The control unit 1400 can control the alignment of the first leg massage unit 1310 and the second leg massage unit 1330 based on at least one of the signals received from the light receiving sensor 1330a and the information received from the encoder.
The user can operate the first leg massage unit 1310 and the second leg massage unit 1330 to simultaneously ascend or descend. The first leg massage unit 1310 and the second leg massage unit 1330 can ascend or descend to a predetermined target coordinate under the control of the control unit 1400. The target coordinate can represent the rotational angular displacement of the first leg massage unit 1310 and the second leg massage unit 1330.
When the first leg massage unit 1310 and the second leg massage unit 1330 rise or descend simultaneously, the control unit 1400 can determine whether the signal from the light emitting sensor 1310a is received/sensed by the light receiving sensor 1330a.
(Route 1-1): When the light receiving sensor 1330a receives a signal, the control unit 1400 can maintain the ascending or descending speed of the first leg massage unit 1310 and the second leg massage unit 1330. The control unit 1400 can continuously/periodically determine whether the signal from the light emitting sensor 1310a is received/sensed by the light receiving sensor 1330a until the first leg massage unit 1310 and the second leg massage unit 1330 reach the target coordinate. While the signal reception is maintained by the light receiving sensor 1330a, the control unit 1400 can maintain the ascending or descending speed of the first leg massage unit 1310 and the second leg massage unit 1330. When the first leg massage unit 1310 and the second leg massage unit 1330 reach the target coordinate, the control unit 1400 can stop the ascending or descending operation of the first leg massage unit 1310 and the second leg massage unit 1330.
(Route 1-2): If the light receiving sensor 1330a does not receive the signal from the light emitting sensor 1310a before the first leg massage unit 1310 and the second leg massage unit 1330 reach the target coordinate, the control unit 1400 can decelerate the speed of either the first leg massage unit 1310 or the second leg massage unit 1330. Subsequently, the control unit 1400 can determine whether the distance between the first leg massage unit 1310 and the second leg massage unit 1330 is decreasing. The control unit 1400 can compare the rotation angles of the first leg massage unit 1310 and the second leg massage unit 1330 based on the information received from the encoder, and determine whether an angle (or difference in encoder values or spacing between encoders) between the first and second leg massage units (1310, 1330) is decreasing, thereby determining whether the distance between the first leg massage unit 1310 and the second leg massage unit 1330 is decreasing.
When the angle is decreased, the control unit 1400 can determine that the distance between the first leg massage unit 1310 and the second leg massage unit 1330 is decreasing. When the angle is increased, the control unit 1400 can determine that the distance between the first leg massage unit 1310 and the second leg massage unit 1330 is increasing.
(Route 1-2-1): When the control unit 1400 determines that the distance between the first leg massage unit 1310 and the second leg massage unit 1330 is decreasing, the control unit 1400 can maintain the speed of the first leg massage unit 1310 and the second leg massage unit 1330 until the light receiving sensor 1330a receives a signal. For example, if the speed of the first leg massage unit 1310 has been decelerated, the control unit 1400 can maintain the decelerated speed of the first leg massage unit 1310 and the speed of the second leg massage unit 1330 until the light receiving sensor 1330a receives a signal. Conversely, if the speed of the second leg massage unit 1330 has been decelerated, the control unit 1400 can maintain the decelerated speed of the second leg massage unit 1330 and the speed of the first leg massage unit 1310 until the light receiving sensor 1330a receives a signal.
When the light receiving sensor 1330a receives a signal, the control unit 1400 can synchronize the speed of the first leg massage unit 1310 and the speed of the second leg massage unit 1330. For example, the control unit 1400 can equalize the speeds of the first and second leg massage units 1310 and 1330 to the preset/initial speed or adjust them to the final speed of the combined first and second leg massage units 1310 and 1330. In the latter case, specifically, if the speed of the first leg massage unit 1310 has been decelerated, the control unit 1400 can adjust the speed of the second leg massage unit 1330 to match the deceleration speed of the first leg massage unit 1310. Similarly, if the speed of the second leg massage unit 1330 has been decelerated, the control unit 1400 can adjust the speed of the first leg massage unit 1310 to match the deceleration speed of the second leg massage unit 1330.
When the first leg massage unit 1310 and the second leg massage unit 1330 reach the target coordinate, the control unit 1400 can stop the upward or downward movement of both the first leg massage unit 1310 and the second leg massage unit 1330.
(Route 1-2-2): If the control unit 1400 determines that the distance between the first leg massage unit 1310 and the second leg massage unit 1330 is increasing, the control unit 1400 can accelerate (or return to the original speed) one of the first leg massage unit 1310 and the second leg massage unit 1330 with a decreased rotational speed and decelerate the other. Subsequently, the control unit 1400 can again determine whether the distance between the first leg massage unit 1310 and the second leg massage unit 1330 is decreasing. If it is determined that the distance is decreasing, the subsequent operations are the same as those described in “Route 1-2-1”.
The first leg massage unit 1310 and the second leg massage unit 1330 can simultaneously move upward or downward by user manipulation. The first leg massage unit 1310 and the second leg massage unit 1330 can be raised or lowered to predetermined target coordinates by the control unit 1400. When the first leg massage unit 1310 and the second leg massage unit 1330 are simultaneously raised or lowered, the control unit 1400 can determine whether the signal from the light emitting sensor 1310a is received by the light receiving sensor 1330a.
(Route 2-1): If the light receiving sensor 1330a receives a signal, the control unit 1400 can maintain the upward or downward speed of the first leg massage unit 1310 and the second leg massage unit 1330. The control unit 1400 can continuously determine whether the light receiving sensor 1330a receives the signal until the first leg massage unit 1310 and the second leg massage unit 1330 reach the target coordinates. While the signal reception is maintained at the light receiving sensor 1330a, the control unit 1400 can maintain the upward or downward speed of the first leg massage unit 1310 and the second leg massage unit 1330. When the first leg massage unit 1310 and the second leg massage unit 1330 reach the target coordinates, the control unit 1400 can stop the upward or downward movement of the first leg massage unit 1310 and the second leg massage unit 1330.
(Route 2-2): If the light receiving sensor 1330a does not receive the signal from the light emitting sensor 1310a before the first leg massage unit 1310 and the second leg massage unit 1330 reach the target coordinates, the control unit 1400 can decelerate the speed of any one of the first leg massage unit 1310 and the second leg massage unit 1330. Subsequently, the control unit 1400 can determine whether there is a decrease in the distance between the first leg massage unit 1310 and the second leg massage unit 1330.
(Route 2-2-1): If the control unit 1400 determines that the distance between the first leg massage unit 1310 and the second leg massage unit 1330 is decreasing, the control unit 1400 can maintain the speed of the first leg massage unit 1310 and the second leg massage unit 1330. Subsequently, the control unit 1400 can determine whether either the first leg massage unit 1310 or the second leg massage unit 1330 has reached the target coordinates.
(Route 2-2-1-1): If the control unit 1400 determines that either the first leg massage unit 1310 or the second leg massage unit 1330 has reached the target coordinates, the control unit 1400 can stop the one that has reached the target coordinates and continue to raise or lower the other one. Subsequently, the control unit 1400 can raise or lower the other one until the light receiving sensor 1330a receives the signal from the light emitting sensor 1310a. Thereafter, when a signal from the light emitting sensor 1310a is received by the light receiving sensor 1330a, the control unit 1400 can stop the operation of the other one
(Route 2-2-1-2): If the control unit 1400 determines that any one of the first leg massage unit 1310 and the second leg massage unit 1330 has not reached the target coordinates, the control unit 1400 can determine whether a signal from the light emitting sensor 1310a of the light receiving sensor 1330a is received.
(Route 2-2-1-2-1): When the light receiving sensor 1330a receives a signal, the control unit 1400 can align the speeds of the first leg massage unit 1310 and the second leg massage unit 1330. For example, the control unit 1400 can align the speeds of the first and second leg massage units 1310 and 1330 to the pre-set/initial speed or match them with the final speed of the second or first leg massage unit 1330 or 1310. In the latter case, if the speed of the first leg massage unit 1310 is decelerated, the control unit can adjust the speed of the second leg massage unit 1330 to the deceleration speed of the first leg massage unit 1310, and if the speed of the second leg massage unit 1330 is decelerated, the control unit 1400 can adjust the speed of the first leg massage unit 1310 to the deceleration speed of the second leg massage unit 1330. When the first leg massage unit 1310 and the second leg massage unit 1330 reach the target coordinates, the control unit 1400 can stop the upward or downward movement of the first leg massage unit 1310 and the second leg massage unit 1330.
(Route 2-2-1-2-2): If the light receiving sensor 1330a does not receive a signal, the control unit 1400 can perform the operation described in ‘Route 2-2-1’.
(Route 2-2-2): If the control unit 1400 determines that the distance between the first leg massage unit 1310 and the second leg massage unit 1330 is increasing, the control unit 1400 can increase the speed of one unit whose rotational speed has decreased, among the first leg massage unit 1310 and the second leg massage unit 1330, and decrease the speed of the other unit. Subsequently, the control unit 1400 can again determine whether there is a decrease in the distance between the first leg massage unit 1310 and the second leg massage unit 1330, and if a decrease is determined, the subsequent operation is the same as ‘Route 2-2-1’.
Although not described in
In one embodiment, the control unit 1400 can set/tune the speed of the adjusted leg massage unit to the base speed during alignment. More specifically, if the speed of the first or second leg massage unit 1310 or 1330 is decelerated or increased from the first speed to the second speed during alignment, the control unit can tune/set the base speed of the first or second leg massage unit 1310 or 1330 to the second speed.
Alternatively, in another embodiment, the control unit 1400 can collect the speed adjustment results of the leg massage units and tune the speeds of the two leg massage units based on the collected results. More specifically, after performing alignment operations of the first or second leg massage unit 1310 or 1330n times, the control unit can collect the results of n times of performances and calculate the average adjustment speed value of the first or second leg massage unit 1310 or 1330. Using the calculated average adjustment speed value, the control unit 1400 can tune the base speed of the first or second leg massage unit 1310 or 1330. As the n value is higher, the alignment accuracy is increased, but the n value is lower, the alignment accuracy is decreased.
Once the speed tuning/setting is performed, the first and second leg massage units 1310 and 1330 will ascend or descend with the tuned/set speed as the base speed in subsequent massage operations. The tuning/setting operations can be repeated multiple times during the massage process, and continuous tuning/setting will result in a continuous reduction in the speed difference between the first and second leg massage units 1310 and 1330.
The first leg massage unit 1310 and the second leg massage unit 1330 can be arranged in a crossed state. The crossed state refers to a configuration where the first and second leg massage units 1310 and 1330 are offset in the width direction (for example, one of the first or second leg massage units 1310 and 1330 is ascending while the other is descending). In this state, the light receiving sensor 1330a does not receive the signal from the light emitting sensor 1310a.
The control unit 1400 can stop any one of the first and second leg massage unit 1310 and 1330 that reaches the target coordinates (e.g., the top, bottom, or center coordinates of the leg massage unit 1300) if one of the first and second leg massage unit 1310 and 1330 descends towards the target coordinates while the other continues to ascend towards the same target coordinates.
Subsequently, the control unit 1400 can continue to ascend or descend the other unit that has not reached the target coordinates until the light receiving sensor 1330a receives the signal from the light emitting sensor 1310a. When the light receiving sensor 1330a receives the signal from the light emitting sensor 1310a, the control unit 1400 can stop the movement of the other unit.
With this embodiment, the two leg massage units in the crossed state can be aligned.
As described above, the control unit 1400 of the massage apparatus 1000 according to an embodiment of the present invention can adjust the alignment state of the first leg massage unit 1310 and the second leg massage unit 1330 through the alignment sensor units 1310a and 1330b, thereby providing an effect of aligning the first and second leg massage units.
Although the present invention has been described with reference to exemplary embodiments along with the accompanying drawings, it should be understood that this is merely exemplary and not intended to limit the present invention. Furthermore, it is evident to those skilled in the art that various modifications and variations can be made within the scope of the technical concept of the present invention without departing from the scope thereof.
Additionally, the configuration and functions of the massage apparatus in this specification can be expanded and applied to various (wearable) healthcare devices capable of providing healthcare functions (e.g., massage functions, biometric signal measurement functions, etc.). Therefore, the term ‘massage apparatus’ in this specification can be replaced with ‘(wearable) healthcare device’ as well.
