Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to the operation of a treatment finger of a massage machine, and specifically to a massage machine capable of performing uniform rolling massage.
[0002]
[Prior art]
Conventionally, a chair-type or bed-type massage machine that massages an affected area such as a shoulder or a waist of a user is known. In this type of device, a pair of treatment fingers are provided inside the back contact portion against which the back of the user hits, and the treatment fingers are moved closer to and away from each other by a motor that reciprocates in the lateral direction, thereby pinching the affected area. Or performing a rolling massage on the affected part by moving the treatment finger up and down by a motor that reciprocates in the longitudinal direction of the backrest.
[0003]
[Problems to be solved by the invention]
In a conventional massage machine, when “rolling squeezing / striking massage” is performed in which the treatment finger rolls while squeezing or tapping, the upper and lower necks and waists of the treatment finger are in the middle. Compared to the back part, there was an inconvenience with less massage. Specifically, when the kneading operation is performed once at each of the upper, middle, and lower ends of the rolling, the upper and lower ends can only be masticated once during the rolling reciprocation. In the middle, since the kneading operation is performed twice, massage is reduced at the upper and lower ends which are the switching positions in the rolling direction.
In many cases, the part that the user desires to massage with particular emphasis is the shoulder and the waist. However, in conventional massage machines, these portions often coincide with the switching position in the rolling direction, and thus sufficient massage cannot be applied to these portions while performing rolling. Therefore, since effective massage cannot be performed by rolling massage, it was necessary to massage and hit massage in a fixed position without performing rolling in order to perform massage focused on the shoulder and waist. However, local massage has the disadvantage that it is poor in change and easy to get bored.
[0004]
  The purpose of the present invention is toDuring rolling massage massage or rolling strike massage that rolls while massaged or hitting the treatment finger, at the switching position in the rolling direction,Stop the rolling motion and perform massage or hit massage a predetermined number of times, evenly over the entire rolling range.Rolling massage massage and rolling massageIt is to provide a massage machine that can be performed.
[0005]
[Means for solving problems]
  In order to solve the above problems, a massage machine according to the present invention includes a pair of treatment fingers disposed on a backrest portion of a chair, a bed, etc. on which a user's back hits, and the treatment finger in the longitudinal direction of the backrest portion. The lifting / lowering means for performing a rolling massage on the whole or a part of the waist from the neck of the user and the reciprocating means for applying the massage finger to drive or massage the finger. The massage machine comprises control means electrically connected to the lifting means and the reciprocating means, the control means comprising:During rolling tapping massage or rolling massage massage driven by lifting means and reciprocating means at the same time, at the switching position in the rolling direction,The lifting / lowering operation by the lifting / lowering means is temporarily stopped, massage or hitting massage by the reciprocating means is performed a plurality of times, and then the lifting / lowering operation by the lifting / lowering means is resumed..
[0006]
[Action and effect]
  During rolling tapping massage or rolling massage massage, at the switching position in the rolling directionThe rolling operation is temporarily stopped, and in that state, the kneading or hitting operation is performed a plurality of times. After rolling and hitting a specified number of times, restart the rolling operation.
  TraditionalRolling tapping massage or rolling massage massageIn particular, massage at the upper and lower ends of the rolling range, i.e., at the switching position in the rolling direction, is insufficient, but if the rolling operation is temporarily stopped at the switching position in the rolling direction and massage is performed multiple times, this massage is performed. Can compensate for the lack of massage in the part and is uniform over the entire rolling rangeRolling tapping massage or rolling massage massageCan be performed.
  In addition,In addition to the switching position in the rolling direction, once the treatment finger is lifted and lowered in the rolling transition path, and massage is performed multiple times at that part, sufficient massage is given along the rolling transition path. Can do. In addition, since the massage operation can be varied, the user is not bored with the massage.
[0007]
The reciprocating means can adjust the driving speed of the treatment finger, and the control means can determine the number of times that the reciprocating means squeezes or strikes the massage when the lifting means is temporarily stopped. It may be increased if the driving speed is high.
When the treatment finger is driven at a slow speed, the massage treatment power to the affected area is small, and therefore, effective massage can be performed by increasing the number of times of itching and hitting.
Further, when the treatment finger is driven at a high speed, the massage treatment force on the affected area is also increased, so that a sufficient massage can be obtained even if the number of squeezing and hitting in the same place is reduced.
Thus, according to the driving speed of the treatment finger, it is possible to perform a more effective massage by changing the number of massages and hitting massages when the lifting / lowering operation is temporarily stopped.

The encoder (35) is connected to a control circuit described later.
[0011]
As shown in FIG. 3, the massage unit (28) has a pair of rollers (40) (40) (40) (40) which are fitted in the grooves of the guide rails (22) and (22). A side plate (41) (41) is provided with an upper support rod (43) and a lower support rod (44) for connecting the upper and lower ends of the side plate (41) (41), respectively. The lower support rod (44) includes an elevating member (45) having a screw hole that meshes with the screw shaft (30), and the screw shaft (30) is rotated by driving the elevating motor (32). The massage unit (28) moves up and down along the guide rails (22) and (22) by the screw thrust.
As shown in FIG. 2, the movement limit of the massage unit (28) in the up-and-down direction is detected by limit switches (47) and (48) respectively provided above and below the one guide rail (22). When the massage unit (28) reaches the upper or lower movement limit, the limit switch (47) (48) hits the upper support rod (43) or the lower support rod (44), and the massage unit (28 ) Is detected to reach the limit, and is transmitted to the control circuit (37).
[0012]
A gear box (50) is provided in the approximate center of the upper and lower support rods (43) and (44). The gear box (50) has a stagnation shaft (51) that penetrates in the left-right direction and rotates at a low speed, and passes through the gear box (50) in the left-right direction below the stagnation shaft (51) and rotates at a high speed. It has a hitting shaft (52). Further, a massage shaft (53) for driving these two shafts (51) (52) protrudes from the bottom surface of the gear box (50). A pulley (54) is fitted to the lower end of the massage shaft (53), and the pulley (54) is passed through a pulley (56) and a belt (57) of a massage motor (55) attached to the lower support rod (44). The massage shaft (53) rotates forward or backward by the rotation of the massage motor (55).
The description of the internal structure of the gear box (50) is omitted, but the operation is to rotate only the massaging shaft (51) at a low speed in the direction of arrow A in FIG. 3 when the massage shaft (53) is rotated forward. When the massage shaft (53) is rotated in the reverse direction, the stab shaft (51) does not rotate when the massage shaft (53) is rotated in the reverse direction. Only known ones rotate at a high speed in the direction of arrow B in FIG.
The pulley (54) provided on the massage shaft (53) includes an encoder (not shown), and the number of rotations of the massage shaft (53) is detected. The encoder is electrically connected to a control circuit (37) described later.
[0013]
The stagnation shaft (51) is a shaft located on the upper side of the gear box (50), and both ends (51a) of the shaft protruding from the gear box (50) are bent in the same direction. As shown in FIG. 5, a projecting piece (61) having a magnet (60) therein is formed at one end of the stagnation shaft (51) on the same side as the bending direction of the end. A board (66) including three reed switches (63), (64) and (65) is disposed on the wall surface of the gear box (50) so as to face the rotation transition path of the magnet (60). One reed switch is provided above, behind and below the stagnation shaft. These reed switches (63), (64), and (65) are electrically connected to the control circuit (37). When the upper reed switch (63) detects the magnet (60), the gap between the kneading balls (70) (70), which will be described later, is farthest away, and the lower reed switch (65) detects the magnet (60). When this is done, the distance between the opposing massaging balls is closest. Further, since the kneading shaft (51) rotates in the direction of arrow A in FIG. 3, when the rear reed switch (64) detects the magnet (60), the kneading ball shifts from the separated state to the approaching state. It means that the interval between the kneading balls facing each other is intermediate between approaching and separating.
[0014]
The hitting shaft (52) is a shaft located below the gear box (50), and both ends (52a) of the shaft protruding from the gear box (50) are as shown in FIG. Are eccentric from each other by a distance H. The eccentric directions of the end portions are symmetrical to each other, that is, shifted by 180 °.
[0015]
The treatment fingers (71) (71) are arranged on the left and right of the gear box (50) as shown in FIGS. The treatment finger (71) is a pair of kneading balls (70) attached inward to both ends of a plate-like arm (72) bent substantially in the center in a dogleg shape.
The arm (72) is pivotally supported by the plate-like lever (73) at the bent portion. The base end of the lever (73) is pivotally supported by the end of the stagnation shaft (51) so as to freely rotate. Since the end portion (51a) of the stagnation shaft (51) is bent as described above, the lever (73) is attached while being inclined with respect to the stagnation shaft (51), and when the stagnation shaft (51) rotates. The lever (73) swings from side to side due to the inclination of the end (51a).
A connecting rod (75) is attached to the lower end of the lever (73) via a ball joint (74), and the connecting rod (75) is an eccentric member (76 provided at the end of the hitting shaft (52). ) And is connected to it.
[0016]
In each arm (72), pins (77) and (78) for restricting the swing angle of the arm (72) with respect to the lever (73) are provided so as to protrude vertically. The arm (72) is connected to the lever (73) and the spring (79) at a position below the lower pin (78). The spring (79) always urges the lower part of the arm (72) in the lever direction. Therefore, in the unloaded state, the lower pin (78) is in contact with the lever (73) by the biasing force of the spring (79). When massage is started and the massaging ball (70) is pressed against the user, the massaging ball (70) is swung within the range of oscillation with respect to the lever (73) against the biasing force of the spring (79). It is possible to move.
[0017]
Each operation of the massage machine (10) is performed by a command from an operation unit (not shown). The operation unit has an elevating button that adjusts the height of the massage unit (28) to `` up, down '', a kneading button that starts the kneading operation, a tapping button that starts the tapping operation, and the interval between the kneading balls is `` wide, middle Width adjustment button to adjust to any of ", narrow", speed adjustment button to adjust the speed of kneading operation, hitting operation to any of "fast, medium, slow", operation 1 button to start operation 1 described later, reclining A reclining button for operating the mechanism and a stop button for stopping each operation are provided. The command signal input to the operation unit when the user presses the button is transmitted to the control circuit (37).
[0018]
A circuit serving as a control means for the operation of the massage machine (10) will be described.
FIG. 6 shows a control circuit (37) mainly composed of a microcomputer. The control circuit (37) is disposed at a proper position of the massage machine (10).
The microcomputer (80) includes a massage motor drive circuit (82) for controlling the drive of the massage motor (55), the output value of the encoder (58) disposed on the pulley (54) of the massage shaft (53), and the kneading shaft. A massage detection circuit (83) for receiving an output value from the reed switches (63), (64) and (65) for detecting the rotation angle of (51) is connected.
The massage motor drive circuit (82) includes a PWM circuit (not shown), performs pulse width modulation, adjusts the drive average voltage supplied to the massage motor (55), and rotates the massage motor (55). Can be controlled.
The massage detection circuit (83) measures whether the massage motor (55) is rotating at a predetermined rotation speed by detecting an encoder pulse, and if it is out of the predetermined rotation speed, the massage motor drive circuit (82 ) To adjust the supply voltage. Further, the output values from the reed switches (63), (64) and (65) are received, and the interval between the kneading balls (70) and (70) facing each other is determined.
[0019]
The microcomputer (80) includes a lift motor drive circuit (84) for controlling the drive of the lift motor (32), an output value of the encoder (35) for detecting the rotation speed of the screw shaft (30), and a massage unit (28 ) Is connected to a lift position detection circuit (85) for receiving output values from upper and lower limit switches (47) and (48) for detecting upper and lower limits.
The number of rotations of the screw shaft (30) from the state in which the upper limit switch (47) detects the massage unit (28) is integrated by the lift position detection circuit (85) as an integrated value of the encoder pulse, and the massage unit (28 ) Is measured. The current position of the massage unit (28) can also be measured with reference to both the lower limit switch (48) or the upper and lower limit switches (47) (48).
[0020]
Further, an operation unit I / F circuit (87) that receives an operation signal from the operation unit (86) is connected to the microcomputer (80). As described above, the microcomputer (80) has a number of operation buttons, and command signals from these buttons are transmitted to the microcomputer (80) via the operation unit I / F circuit (87), and various controls are performed. Done.
[0021]
Further, the control circuit (37) is provided with a reclining control circuit (89) for controlling the reclining mechanism (24) and swinging the backrest portion (14). The reclining control circuit (89) is well known and will not be described.
[0022]
Operation explanation
First, the basic operation of the massage machine (10) will be described. In addition, the massage operation | movement of this invention is the operation | movement 1 mentioned later.
When the massage machine (10) is turned on, the initial position of the massage unit (28) is confirmed. This is for determining the amount of movement of the massage unit (28) by integrating or subtracting the number of pulses of the encoder (35) provided on the screw shaft (30). In the present invention, the initial position of the massage unit (28) is set as the upper movement limit position where the massage unit (28) and the upper limit switch (47) hit. Accordingly, the massage unit (28) moves upward until it is detected by the upper limit switch (47). When the upper limit switch (47) detects the massage unit (28), the integrated value of the encoder pulse of the screw shaft (30) is reset.
From this state, each operation of the massage machine (10) can be performed.
[0023]
[Massage unit lifting and lowering]
When the user presses one of the “up” and “down” buttons, the command signal is sent to the control circuit (37) and sent to the microcomputer (80) via the operation unit I / F circuit (87). The signal is input and output to the lift motor drive circuit (84) as an UP signal or a DOWN signal. In response to the signal, the elevating motor (32) rotates in a predetermined direction. The number of rotations of the screw shaft (30) by the lifting motor (32) is counted as an integrated value when the massage unit (28) is moving down, and the massage unit (28) is raised. When the operation is performed, the number of encoder pulses is subtracted from the integrated value. The current position of the massage unit (28) can be determined from the integrated value of the encoder pulse.
The massage unit (28) can move up or down and stop at any position until it is detected by any of the upper and lower limit switches (47) (48).
[0024]
[Mixing motion]
When the user presses the massage button, a command signal is similarly sent to the control circuit (37) and input to the microcomputer (80) via the operation unit I / F circuit (87), and the massage motor drive circuit ( 82) is output as a MSG signal. When the massage motor drive circuit (82) receives the MSG signal, it rotates the massage motor (55) so that the massage shaft (53) rotates forward, and only the massage shaft (51) is moved in the direction of arrow A in FIG. Drive to rotate. Since the lever (73) is pivotally supported with respect to the rotation center of the kneading shaft (51), when the kneading shaft (51) is rotated, the kneading ball (70) is indicated by an arrow C in FIG. As described above, the massaging balls (70) and (70) facing each other perform a reciprocating motion substantially parallel to the left-right direction so that massage is given to the user. At this time, the lower end of the lever (73) is pivotally supported by the eccentric member (76) via the ball joint (74) and the connecting rod (75) so that the tilting movement of the lever (73) is obstructed. There is no.
When the kneading shaft (51) rotates, the reed switches (63), (64), (65) provided in the gear box (50) sequentially detect the magnet (60). When each reed switch detects the magnet (60), the detection signal is transmitted to the massage detection circuit (83). When the upper reed switch (63) detects the magnet (60), a signal (WIDE signal) indicating that the gap between the kneading balls (70) and (70) is in the widest state is sent to the massage detection circuit (83). When the rear reed switch (64) detects the magnet (60), the signal indicating that the gap between the kneading balls (70) and (70) is intermediate (MIDDLE signal), and the lower reed switch (65) When the magnet (60) is detected, a signal (NARROW signal) indicating that the interval between the kneading balls (70) and (70) is in the narrowest state is sequentially transmitted to the massage detection circuit (83).
[0025]
It is also possible to change the interval between the massaging balls (70) and (70) without performing the massaging operation, that is, only to adjust the width. In this case, when the width adjustment button on the operation unit is pressed and either of the kneading ball intervals “wide, medium, narrow” is selected, a MSG signal is transmitted to the massage motor drive circuit (82), and the massage motor (55) is Rotate only the kneading shaft (51). By the rotation of the kneading shaft (51), the interval between the kneading balls (70) and (70) changes, and signals indicating the kneading ball interval are sequentially detected from the reed switches (63), (64) and (65). When a predetermined signal (WIDE signal, MIDDLE signal, or NARROW signal) indicating the kneading ball interval selected by the user is detected, the massage motor drive circuit (82) drives the massage motor (55). Stop and stop the kneading balls (70) (70) from moving. Thereby, the kneading ball interval becomes a desired interval of the user.
In this state, if the massage unit (28) is moved up and down, a rolling massage can be performed, and if a hitting operation is performed, a hitting massage can be performed at a kneading ball interval desired by the user.
[0026]
[Striking motion]
When the user presses the hit button, a command signal is sent to the control circuit (37) and is input to the microcomputer (80) via the operation unit I / F circuit (87), and then to the massage motor drive circuit (82). Output as TAP signal. When receiving the TAP signal, the massage motor drive circuit (82) drives the massage motor (55) so that the massage shaft (53) rotates in the reverse direction, and rotates only the strike shaft (52) in the direction of arrow B in FIG. Drive. The eccentric member (76) is pivotally supported eccentrically with respect to the rotation center of the hitting shaft (52), and the base end of the lever (73) is pivotally supported by the non-rotating stagnation shaft (51). When (52) is rotated, the kneading balls (70) and (70) reciprocate substantially vertically as shown by the arrow D in FIG. 4 to strike and massage the user. When the massage shaft (53) rotates once, the hitting shaft (52) also rotates once and a single hitting operation is performed. That is, the number of encoder pulses from the encoder (58) arranged on the pulley (54) of the massage shaft (53) and the number of hits are set to coincide with each other.
[0027]
In the kneading operation and the hitting operation, the rotation speed of the massage motor (55) can be changed to adjust the operation speed of the kneading balls. The operation speed is adjusted by pressing the speed adjustment button on the operation unit and selecting one of the speeds “fast, medium, slow” by the PWM circuit (not shown) of the massage motor drive circuit (82). ) By adjusting and applying the drive average voltage to. When the rotation speed of the massage motor (55) is adjusted to a desired speed, the speed of the kneading balls (70) (70) operated by the motor (55) changes. Whether the kneading balls (70) (70) are adjusted to the desired speed is determined by measuring the pulse interval of the encoder from the encoder (58) arranged on the pulley (54) of the massage shaft (53). it can.
[0028]
[Operation 1]
The rolling massage operation of the present invention will be described with reference to the timing chart of FIG. 7 and the flowchart of FIG. In the following, rolling tapping massage, that is, massage that strikes with a kneading ball while raising and lowering the massage unit will be described. However, by rotating the rotation direction of the massage motor and changing the tapping action to kneading, rolling A massage massage can be performed as well.
[0029]
Hereinafter, a massage operation in which the number of hits at both ends of the rolling transition path of the massage unit (28) is increased will be described. Here, X is the number of times the treatment finger is struck while the massage unit (28) is moving up and down, and Y is the number of times that the massage unit (28) is struck at both ends of the rolling transition path.
[0030]
First, after the massage unit (28) is moved to a desired height position, the operation 1 button of the operation unit is pressed (step 1), and the operation 1 command signal is transmitted to the control circuit (37).
Upon receiving the command signal, the microcomputer (80) transmits a TAP signal (see FIG. 7) to the massage motor drive circuit (82), drives the massage motor (55), and massages (70) (70) Is driven (step 2).
In this state, the lifting / lowering of the massage unit (28) is stopped.
[0031]
The number of encoder pulses of the massage shaft (53) is counted by the massage detection circuit (83), and when the number of pulses reaches a predetermined value Y (see FIG. 7), it is detected that the hitting operation has been performed a predetermined number of times. Then (step 3), a DOWN signal is transmitted to the lifting motor drive circuit (85) ((1) in FIG. 7), and the lifting motor (32) is driven to lower the massage unit (28) ( Step 4).
Rolling and tapping massage is performed by simultaneously performing tapping and rolling by lowering the massage unit.
[0032]
During the lowering operation of the massage unit, the massage detection circuit (83) counts the number of encoder pulses of the massage shaft (53), and when the number of pulses reaches a predetermined value X (step 5), the lift motor drive circuit (85 ) Is stopped (step 6, FIG. 7 (2)), and the drive of the lifting motor (32) is stopped.
During the descending operation of the massage unit, X hitting operations are performed, and the massage unit (28) reaches the lower limit position of the rolling transition path.
[0033]
The tapping operation is repeated until the number of encoder pulses of the massage shaft (53) reaches a predetermined value Y at the rolling transition path lower limit position of the massage unit (28). When the number of encoder pulses reaches a predetermined value Y (step 7), an UP signal is transmitted to the lift motor drive circuit (85) ((3) in FIG. 7) to raise the massage unit (28) (step 8). .
Ascending operation and hitting operation of the massage unit (28) are performed simultaneously, so that rolling hitting massage in the rising direction is performed.
[0034]
During the ascending operation of the massage unit, the massage detection circuit (83) similarly counts the number of encoder pulses of the massage shaft (53), and when the number of pulses reaches a predetermined value X (step 9, ▲ 4 in FIG. 7). ▼), the transmission of the UP signal by the lift motor drive circuit (85) is stopped (step 10), and the drive of the lift motor (32) is stopped. During the ascending operation of the massage unit, X hitting operations are performed, and the massage unit (28) reaches the upper limit position of the rolling transition path.
[0035]
When the massage unit (28) reaches the rolling transition path upper limit position, the process returns to Step 3.
This cycle is repeated until the stop button is pressed or a stop command by a timer or the like is transmitted.
[0036]
With the rolling hit massage of the present invention, many hits can be performed at the upper limit and lower limit positions of the rolling transition path. Therefore, massage is sufficiently performed even on a portion where the massage is insufficient with the conventional rolling hit massage.
[0037]
In the above rolling hitting massage, the rolling range of the massage unit (28) is determined by the number of hits X, but the rolling range is determined by the number of pulses of the encoder (35) of the screw shaft (30) that moves the massage unit (28) up and down. May be. Also, with the rolling range as the total length of the guide rail (22), continue the lifting and lowering operation while hitting until the upper and lower limit switches (47) and (48) detect the massage unit (28). When the massage unit (28) is detected by the switches (47) and (48), the lifting / lowering can be stopped and the tapping operation can be performed Y times.
[0038]
FIG. 9 shows another embodiment of the present invention. In the middle of rolling descent or ascending transition, the rolling operation is temporarily stopped, the hitting operation is performed at that position, and the rolling descent is performed after a predetermined number of times. Alternatively, the ascending operation is continuously performed.
As shown in FIG. 9, after hitting Y times at the rolling upper limit position, a DOWN signal is transmitted in the same manner as in operation 1, the massage unit is lowered, and X hitting operations are performed during the descent. Then, the transmission of the DOWN signal is stopped, the descent operation of the massage unit is stopped, and the tapping operation is performed Y times at that position. After the hit operation is performed Y times, the massage unit is lowered while performing the hit operation by transmitting the DOWN signal again. This descent and stop is repeated a predetermined number of times to reach the massage unit to the rolling lower limit position. When the massage unit reaches the rolling lower limit position, the hitting operation is performed Y times at the lower limit position, and thereafter, ascending and stopping are repeated in the same manner as when descending, and rolling hitting massage is performed.
According to the present embodiment, sufficient massage can be performed not only in the rolling upper limit and the lower limit position but also in the middle of the rolling transition path, so that a more effective massage can be performed.
In this embodiment, if the number of stabs or hits at the switching position in the rolling direction is increased more than the number of hits when the massage unit is moving up or down, a more uniform massage is performed over the entire rolling range. be able to.
This embodiment can be implemented not only for the hitting operation but also for the rubbing operation.

In the above two embodiments, it is desirable that the number of hits X and Y can be freely set according to the hitting speed of the kneading balls by the massage motor (55). This is because the massage strength, the length of the rolling range for which massage is desired, and the like vary depending on the user.
For example, when the rotational drive speed of the massage motor (55) is “low”, the hitting speed of the kneading balls is slow, so that the hit given to the user is weak. Therefore, an effective massage can be performed by increasing the number of hits Y when the massage unit is stopped to compensate for the lack of massage strength.
In addition, adjusting the number of hits X is effective because the length of the rolling range of the massage unit can be adjusted and massage can be performed within the rolling range according to the user.
