BACKGROUND OF THE INVENTION
The present invention relates to a massage machine, and more particularly to a massage machine that massages the back of a human body with a pair of left and right treatment elements.
[0002]
[Prior art]
As a massage machine, it has a pair of left and right treatment elements for massage on the back of the human body, a vertical movement mechanism along the spine direction of the human body of this treatment element, a width drive mechanism for changing the left and right spacing of the treatment elements, and a treatment element There is a massage machine equipped with a strength adjustment mechanism that changes the amount of protrusion of the body toward the human body.
[0003]
In a massage machine that can perform massage in such a wide area, there is a part in the human body that should not apply too much pressure in the massage that will apply pressure to the human body with the treatment element. When the treatment element is located at a position corresponding to the above, there is provided a device that ensures safety by preventing the protrusion amount of the treatment element from being increased.
[0004]
Japanese Patent Application Laid-Open No. 5-31147 discloses a method in which the amount of protrusion of the treatment element is controlled in accordance with the vertical position of the back of the human body so that a massage having the same strength can be obtained at both the shoulder position and the waist. Yes.

JP-A-5-31147 [0006]
[Problems to be solved by the invention]
However, the control of the amount of protrusion of the treatment element and the control according to the vertical position are performed only according to the vertical position along the back muscle direction of the human body, and for this reason, at a certain vertical position to ensure safety. When the amount of protrusion is limited, depending on the spacing of the treatment elements, even if the amount of protrusion is further increased and there is no problem with safety, the restriction of the amount of protrusion is effective. In some cases, the massage effect could not be obtained.
[0007]
The present invention has been made in view of these points, and an object of the present invention is to provide a massage machine that can perform a safe and sufficient massage on a wide range of the back of the human body. .
[0008]
[Means for Solving the Problems]
Thus, the present invention comprises a pair of left and right treatment elements for massaging the back of the human body, a vertical movement mechanism along the back muscle direction of the human body of the treatment element, a width drive mechanism for changing the left and right spacing of the treatment elements, In a massage machine equipped with a strength adjustment mechanism for changing the amount of protrusion of the treatment element toward the human body side, the treatment element by the strength adjustment mechanism according to both the vertical position by the vertical movement mechanism and the left and right distance by the width drive mechanism a control means for limiting the range of adjustment of the amount of projection of the Rutotomoni, range for massage treatment element is in accordance with the lateral spacing at the same vertical position by the restriction of the adjustment range of the projection amount of the control means, it is allowed and adjustment range is large portion of the projection amount, has an adjustment range is small portion of the protrusion amount is allowed, the control means, projecting within the adjustment range which is permitted set for each portion Together allow changes, when the adjustment range of Permitted type of protrusion amount at a specific position when moving to a specific position of the treatment elements is small, the moving the treatment element to the particular position after reducing the amount of protrusion It has characteristics. The protrusion amount is limited not only in the vertical position but also in a state corresponding to the left-right distance (width) of the treatment element.
[0009]
In this case, the control means restricts the amount of protrusion when the upper and lower positions correspond to the neck position of the human body and the pair of treatment elements is 160 mm or less, which improves the massage effect on the shoulder position. Is preferable.
[0010]
The strength adjusting mechanism is preferably driven by a unique driving source different from the vertical movement mechanism or the width driving mechanism.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on an example of an embodiment, and various types of massage machines are provided. The massage machine includes a pair of left and right treatment elements 1 and 1 for massage on the back surface of the human body 2. The vertical movement mechanism 3 along the spine direction of the human body 2 of the treatment elements 1, 1, the width driving mechanism 4 that changes the left-right distance (width) of the treatment elements 1, 1, and the treatment elements 1, 1 to the human body side If it is a massage machine provided with the strength adjustment mechanism 5 which changes protrusion amount, what kind of treatment element 1 and 1 may be provided, and it does not ask the kind of said each mechanism.
[0012]
In such a massage machine, the vertical position sensor S1 for detecting the vertical positions Y0 to Y40 of the treatment elements 1 and 1 in order to enable feedback control of the vertical position, left and right distance and protrusion amount of the treatment elements 1 and 1; The width position sensor S2 for detecting the left-right distance (width) X0-X9 of the treatment elements 1, 1 and the protrusion amount sensor S3 for detecting the protrusion amounts Z0 to Z8 of the treatment elements 1, 1 are further provided. In order to ensure safety, for example, if the vertical position is X0, the rule that defines the restriction that the protrusion amount is limited to the range of Z0 to Z5 out of Z0 to Z8 (the movable range of the treatment element is set) Defined control) is held in the position management table T, and the control means C is driven by the vertical movement mechanism 3 and the width drive mechanism 4 at a specific position in accordance with an instruction input from the user. When moving If the adjustment range in which the protrusion amount at a specific position is allowed is smaller than the protrusion amount of the current treatment element 1, 1 with reference to the above rule, the treatment element 1, 1 is placed at that position after reducing the protrusion amount. Do that.
[0013]
Here, in the massage machine according to the present invention, the rule relating to the restriction of the protrusion amount does not correspond only to the vertical position of the treatment elements 1, 1. It corresponds to both the interval (width). In other words, even if the left and right intervals are different even at the same vertical position, the limit of the protrusion amount may be different. FIG. 1 shows an example of this, and in the range from the upper end Y0 close to the head of the human body to the lower end Y40 on the waist and the width is in the range of X0 to X4, the protruding amount is only in the range of Z0 to Z4. When the vertical position is within the range of Y0 to Y11 or Y37 to Y40 and the width is within the range of X5 to X9, the protrusion amount can be adjusted within the entire adjustable range of Z0 to Z8. Within the range of the positions Y12 to Y36, the treatment elements 1 and 1 cannot be positioned in the range of the widths X5 to X9.
[0014]
In this case, when performing massage on the shoulder, upper back, and lower back, the amount of protrusion is suppressed in the part close to the back muscle, so that too much massage is not applied near the spine, and it protrudes on both sides away from the back muscle. Since the amount limit is zero (no limit), an effective massage can be performed on the shoulder, upper back and both sides of the waist.
[0015]
In addition, in the case where massage is performed on the neck 20 portion of the human body 2 and the case where massage is performed on the upper surface 21 of the shoulder, the treatment elements 1 and 1 are at substantially the same vertical position, although the left and right intervals are different. . In this case, when the distance between the pair of left and right treatment elements 1 and 1 is narrowed in a state where the projection amount is Z8 at maximum in order to enable massage on the upper surface of the shoulder, the treatment elements 1 and 1 move the neck of the human body to the left and right. If you give priority to safety, if you give priority to safety, the conventional massage machine adds a restriction that can not increase the protruding amount in the vertical position, that is, against the upper surface of the shoulder It will be in the state which cannot perform a massage.
[0016]
However, in the massage machine according to the present invention, even when the vertical position corresponds to the upper surface of the neck or shoulder, the protrusion amount is Z0 to Z4 only in the range where the distance between the pair of left and right is 160 mm or less (equivalent to X0 to X2). By limiting to the range, safety is ensured by avoiding the situation where the treatment elements 1 and 1 may pinch the neck, and the protrusion amount is not limited when the distance is larger than the above interval (X3 to X9). Thus, the massage on the upper surface of the shoulder can be effectively performed.
[0017]
When controlling in such a state that the vertical position, the width position, and the protrusion amount are associated with each other, the strength adjustment mechanism 5 that changes at least the protrusion amount of the treatment elements 1 and 1 is the vertical movement mechanism 3 or the width drive mechanism. It is preferably one that can be independently adjusted by being driven by a unique driving source different from 4, that is, one that does not change the protruding amount due to width adjustment or the like. The projection amount can be reliably controlled, and the projection amount adjustment range (maximum value of the projection amount) can be easily increased.
[0018]
【The invention's effect】
As described above, in the present invention, the control means for limiting the adjustment range of the protrusion amount of the treatment element toward the human body by the strength adjustment mechanism according to both the vertical position by the vertical movement mechanism and the left-right distance by the width driving mechanism is provided. In addition, the range for performing massage with the treatment element is allowed to be a portion with a large adjustment range of the allowable protrusion amount even in the same vertical position due to the limitation of the adjustment range of the protrusion amount of the control means, depending on the left and right intervals. The control means allows the protrusion amount to be changed within the allowable adjustment range set for each part and moves the treatment element to a specific position. Sometimes when the adjustment range of the allowable protrusion amount at a specific position is small, an effective massage is obtained while ensuring safety in order to move the treatment element to the specific position after reducing the protrusion amount Range Those which can be broadly.
[0019]
In this case, the control means restricts the amount of protrusion when the vertical position corresponding to the neck position of the human body and the distance between the pair of treatment elements is 160 mm or less, ensuring the safety for the neck and the effect of the massage on the shoulder upper surface position. An improvement can be obtained.
[0020]
Further, if the strength adjustment mechanism is driven by a unique drive source different from the vertical movement mechanism or the width drive mechanism, it becomes easy to increase the adjustment range of the protrusion amount and to reliably control the adjustment range.
