Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hitting width at an appropriate position for ascending and descending, for example, at a shoulder position or a waist position, when a treatment element moves up and down while performing a hitting operation. The present invention relates to a massage machine that automatically changes and performs a beating operation. [0002] As a conventional massage machine, there is known a massage machine having a width adjusting device capable of adjusting the width of a treatment element. [0003] However, the width adjusting device in the above-mentioned massage machine adjusts the width of the patient to a desired width. Generally, a tapping width is narrow at a waist position and a shoulder position is narrow. However, while it is preferable to increase the tapping width, there is an inconvenience that the tapping width must be manually changed every time the treatment element is moved up and down. Therefore, it is conceivable to provide a position detector for the treatment element in the process of moving the treatment element up and down, and to operate the width adjusting device when the position detector detects the movement of the treatment element. . In that case, the width adjustment of the treatment element is automatically performed, so that the labor for manual operation can be omitted.
However, if the treatment element is moved up and down and the distance between the treatment elements changes frequently every time the treatment element passes through the position detector, the patient may feel uncomfortable. FIG. 6 is a diagram showing a process of changing the width of a treatment element when a position detector is provided at an intermediate position in the process of moving the treatment element up and down. In the drawing, a thick line indicates that the treatment element has a large width, and a thin line indicates that the treatment element has a small width. As is clear from this figure, the width of the treatment element frequently changes every time the treatment element passes through the intermediate position in the elevating process. FIG. 7 shows that the treatment element moves up and down,
It is a figure which shows the progress which the width | variety of a treatment element changes in the case of providing the high position detector and the low position detector which detect movement of a treatment element each time a treatment element passes. In this figure, the treatment element is raised and lowered from the upper end to the lower end in the initial stage, the treatment element is raised and lowered in the middle stage, and the treatment element is raised and lowered in the end stage.
As is clear from this figure, the width of the treatment element changes conveniently in the initial stage, but the width of the treatment element changes frequently in the middle and final stages. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned technical problem, and an object of the present invention is to automatically change a hitting width when a treatment element moves up and down while performing a hitting operation. An object of the present invention is to provide a massage machine that performs an operation and does not change the width of a treatment element more than necessary. A massage machine according to the present invention is a massage machine having a pair of treatment elements that perform at least a tapping operation and move up and down, and are driven by a motor. The width of the treatment element is detected when the treatment element is moved from the high position to the low position by providing a position detector that detects the position of the treatment element during the elevating movement of the treatment element. The width adjustment device operates so as to widen the distance between the treatment elements when the adjustment device operates to reduce the distance between the treatment elements and detects that the treatment element moves from the low position to the high position. It is. With the above construction, when the treatment element moves up and down while performing the beating operation, the beating operation is performed by automatically changing the beating width at an appropriate position for elevating and lowering, for example, at a shoulder position or a waist position. And, the width of the treatment element changes only when the position detector detects that the treatment element moves from the high position to the low position or from the low position to the high position, and the vertical movement at the high position or the low position Since the width of the treatment element does not change only by detecting the vertical movement of the treatment element, the width of the treatment element does not change more than necessary. Preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings. First, the driving section of the massage machine in the present embodiment will be described. The drive unit uses a pair of treatment elements that serve both the kneading operation and the tapping operation, but is not limited to this, and is a drive unit that performs the kneading operation and the tapping operation with separate treatment elements.

A signal is sent so that the drive unit 12 stops or rotates forward, and the drive unit A is controlled to stop moving up or down or start moving from a low position to a high position. When it is detected that the driving unit A has moved along the rack 18 from the low position detector 32 to the high position detector 31, a signal is sent so that the motor 6 rotates in the reverse direction. When the driving unit A reaches the upper limit of the rack 18 after a certain period of time after the high position detector 31 detects the driving unit A, the distance between the children 15a and 15b is automatically widened. According to the selection, a signal is sent so that the motor 12 stops or rotates in the reverse direction, and control is performed so that the elevation of the drive unit A stops or starts moving from the high position to the low position. Therefore, when the drive unit A moves along the rack 18 in the order from the high position detector 31 to the low position detector 32, the distance between the treatment elements 15a and 15b is automatically reduced, and the drive unit A Move along the rack 18 in order from the low position detector 32 to the high position detector 31, the distance between the treatment elements 15a and 15b is automatically increased. FIG. 3 shows the treatment elements 15a, 15a when the driving section A has passed the high position detector 31 and the low position detector 32.

In the middle stage, when the transition from the initial stage to the middle stage occurs, the distance between the treatment elements 15a and 15b only changes in a direction in which the distance increases, and the driving unit A reciprocates only the high position detector 31. The distance between the treatment elements 15a and 15b is not narrowed, and the treatment elements 15a and 15b are positioned above the back of the patient.
Since the tapping massage is performed without change in a state where the interval of 5b is widened, the user does not feel uncomfortable. Further, in the final stage, when the transition from the middle stage to the final period, the distance between the treatment elements 15a and 15b only changes in a narrowing direction, and the driving unit A reciprocates only the low position detector 32. The distance between the treatment elements 15a and 15b does not increase, and the treatment elements 15a and 15b are arranged below the back of the patient.
Since the tapping massage is performed without change in a state where the interval of 15b is narrowed, the user does not feel uncomfortable. When comparing FIG. 3 in the present embodiment with FIG. 7 in the problem to be solved by the present invention, the change in the distance between the treatment elements is small in FIG. 3 and the massage operation is clearly improved. It can be understood that it is. In the above embodiment, the high position detector 31 and the low position detector 32 are provided at the upper and lower two positions of the rack 18 so as to detect the elevation position of the drive unit A.

When the drive unit A detects that the lower limit has been reached, a signal is sent so that the motor 12 stops or rotates forward according to the selection of the patient, and the elevation of the drive unit A stops or from the low position. It is controlled to start moving to a high position. When it is detected that the drive unit A has moved from the low position to the high position, a signal is sent so that the motor 6 rotates in the reverse direction, and the distance between the treatment elements 15a and 15b is automatically increased. When it is detected that the drive unit A has reached the upper limit, a signal is sent so that the motor 12 is stopped or rotated in reverse according to the selection of the patient, and the elevation of the drive unit A is stopped or from a high position. It is controlled to start moving to a low position. Therefore, when it is detected that the drive unit A has moved from the high position to the low position along the rack 18, the distance between the treatment elements 15a and 15b is automatically reduced, and the drive unit A When it is detected that the user has moved from the low position to the high position along
b automatically increases its interval. The present invention is not limited to the above-described embodiment, but includes a wide variety of modifications without departing from the spirit of the present invention.
