Japanese Patent No. 40467702

  The first treatment finger has a flat spherical kneading ball, but when trying to massage a shoulder massage with a wide area as much as possible, a single kneading ball can only be widened laterally, depending on human fingers The sense of shoulder was different.

  An object of the present invention is to provide a massage unit having a plurality of first treatment fingers and capable of performing a massage massage that is similar to a shoulder massage by a human finger.

In order to solve the above problems, the massage unit of the present invention is
The chassis,
A stagnation motor deployed in the chassis;
A rubbing shaft that is pivotally supported by the chassis and rotated by a rubbing motor, and an oblique shaft that is disposed on the left and right of the main shaft and is inclined with respect to the axis of the main shaft;
An arm part formed with an engagement hole that fits rotatably on the oblique axis, a tip presser that is disposed at the tip of the arm part and massages the affected area of the user, and is formed at the base end of the arm part, A first treatment finger having an angle restricting member that engages with the chassis and restricts the arm portion from rotating integrally with the stagnation shaft;
In a massage unit having
A plurality of first treatment fingers are arranged side by side on the oblique axis.

According to the massage unit of the present invention, the slanted shaft provided to be inclined at the tip of the main shaft of the kneading shaft has a plurality of first treatment fingers.
As the oblique axis is further away from the main shaft, the amount of eccentricity from the main shaft axis increases.
Therefore, when the kneading shaft is rotated, each first treatment finger moves more greatly as the first treatment finger having a larger eccentric amount located at a position away from the main shaft in a direction orthogonal to the axis, and the first treatment finger However, it moves before the first treatment finger with a small amount of eccentricity from the main shaft and moves to the end.
That is, each first treatment finger does not act on the affected area of the user at the same time with the same force, but instead hits the affected area in order from the first treatment finger with the larger amount of eccentricity, and the first treatment finger with the smaller amount of eccentricity hits the affected area. After that, the first treatment finger having a small eccentric amount is first separated from the affected part, and finally the first treatment finger having a large eccentric amount is separated from the affected part.
In addition, since the first treatment finger having a larger amount of eccentricity has a larger swing range, the treatment finger having a larger amount of eccentricity strikes the affected area more strongly.
Accordingly, the treatment force and treatment time applied to the affected area of the user by each first treatment finger are different, and the affected area is massaged with various changes in each first treatment finger, such as a massage by a human hand. Can be applied.

1 and 2 are perspective views of the massage unit (10) of the present invention, and FIG. 3 is a first treatment finger (30) (30a) (30b), a second treatment finger (40) on one side, and a kneading shaft. It is a figure which decomposes | disassembles and shows the edge part of (20).
The massage unit (10) of the present invention includes a plurality of first treatment fingers (30), (30a), (30b) and a second treatment on the left and right of the squeezing shaft (20) rotatably arranged on the chassis (12). It has a finger (40), and by approaching and separating them, the affected part such as the shoulder of the user is sandwiched and massaged.
In the present embodiment, three first treatment fingers are provided (indicated by reference numerals (30), (30a), and (30b)), but the number is not limited to this. Moreover, what is necessary is just to provide a 2nd treatment finger (40) as needed.

  In each figure, in order to make the internal structure of the massage unit (10) easier to understand, the cover, cushion, frame, etc. attached to the outer periphery of the massage unit (10) are removed, but they are actually used. In this case, as shown in FIGS. 9 and 10, a resin cover (60), a cloth cover (61), a cushion, a frame, etc. may be attached as appropriate.

  As shown in FIGS. 1 to 3, the massage unit (10) of the present invention exemplifies a configuration that operates using a kneading motor (14) disposed vertically in the approximate center of the chassis (12) as a drive source. The stagnation motor (14) is connected to a stagnation shaft (20) via a reduction mechanism (15) with gears and the like. 20) can be rotated.

  The stagnation shaft (20) has a straight main shaft (21) connected to the speed reduction mechanism (15) at a substantially central position, and inclined shaft portions (22) attached to both left and right ends of the main shaft (21). ing.

The inclined shaft portion (22) is a member that supports first treatment fingers (30), (30a), and (30b), which will be described later, and as shown in FIG. 4, the tip fitted to the main shaft (21) is cut obliquely. An inclined shaft (25) is connected between the cylindrical mounting members (23) via a flange (24). The attachment member (23) is fixed to the main shaft (21), and the oblique shaft (25) is disposed so as to be inclined with respect to the axis of the main shaft (21). An attachment member (23) is arranged at the tip of the oblique axis (25) so as to be coaxial with the attachment member (23).
The inclination angle of the oblique shaft (25) can be set as appropriate, and the oblique shaft (25) of the inclined shaft portion (22) arranged on both sides of the main shaft (21) projects in the same direction as shown in the figure. It can be attached so that it protrudes in the opposite direction on the left and right.
The mounting members (23) and (23) are supported at both ends by a bearing (13) protruding from the chassis (12).

  As shown in FIGS. 5 and 7, the oblique shaft (25) has a second rod (19) for swinging a second treatment finger (40) described later at a position eccentric from the axis of the oblique shaft (25). A second eccentric cam (27) for reciprocating the second rod (19) is formed.

  A treatment finger that sandwiches the affected area of the user is composed of a pair of upper and lower first treatment fingers (30), (30a), (30b) and a second treatment finger (40) supported by the inclined shaft portion (22). .

The first treatment finger (30), (30a), (30b) has an engagement hole (32) that is rotatably fitted to the oblique axis (25) and protrudes forward as viewed from the chassis (12). (31) and a tip presser (33) formed at the tip of the arm portion (31) and pressing the affected part of the user. Each tip presser (33) is a part that presses the shoulder from the top when massaging the shoulder of the user, and in order to obtain a massage effect similar to a shoulder massage by a person, the finger of each person's hand It is desirable to configure to a width of about.
The first treatment fingers (30), (30a), and (30b) have an engagement hole (32) fitted to the oblique shaft (25) of the inclined shaft portion (22), and the arm portion of the innermost first treatment finger (30a). It is attached to the inclined shaft part (22) so that one side of (31) abuts on the flange (24).

On the base end side of each arm portion (31), an angle restricting projection (36) is provided so as to fit into an angle restricting groove (16) formed in the chassis (12) and form an angle restricting member (17). ing. The angle restricting protrusion (36) prevents the first treatment finger (30) from rotating integrally with the stagnation shaft (20) and fits to the oblique shaft (25) of the inclined shaft portion (22). The arm portion (31) swings in the left-right direction by the rotation of the oblique shaft (25).
Thereby, the left and right first treatment parts (30), (30a), and (30b) can approach and separate in accordance with the rotation of the oblique axis (25) and massage the affected part of the user.

The eccentric amount of the oblique axis (25) increases as the distance from the axis of the main axis (21) increases.
Accordingly, when the eccentric amount of the oblique axis (25) with respect to the main shaft (21) is as shown in FIG. 4, when the stagnation shaft (20) is rotated, the first treatment fingers (30), (30a), (30b) The inner and outer first treatment fingers (30a, 30b) with larger eccentricity located away from the axis (20) in the direction orthogonal to the axis move more, and the inner and outer first treatment fingers with larger eccentricity are larger. The first treatment finger (30a) (30b) moves before the center first treatment finger (30) having a small eccentricity and moves to the end.
That is, the first treatment fingers (30), (30a), and (30b) do not act on the affected area of the user at the same time with the same force, but the inner and outer first treatment fingers (30a) (30a) ( 30b) after hitting the affected area in order, the first first treatment finger (30) with a small amount of eccentricity hits the affected part, and then the first first treatment finger (30) in the middle first leaves the affected area, and finally the inside with a large amount of eccentricity. The outer first treatment fingers (30a) and (30b) are separated from the affected area.
Further, since the swinging range becomes larger as the first treatment finger (30a) (30b) on the inner side and the outer side with a larger eccentric amount becomes larger, the center first of the first treatment finger (30a) (30b) has a smaller eccentric amount. It hits the affected area more strongly than 1 treatment finger (30a).

The movement of the first treatment fingers (30), (30a) and (30b) when the eccentric amount of the oblique axis (25) with respect to the main axis is as shown in FIG. 4 is as described above. For example, the tip of the oblique axis (25) When the side is greatly decentered with respect to the main shaft (21) as compared with the base end side, the outer first treatment finger (30b), the central first treatment finger (30), the inner first treatment finger (30a) ) In this order, and the vertical swing width also increases in this order.
On the contrary, when the base end side of the oblique axis (25) is greatly decentered with respect to the main axis (21) compared to the distal end side, the movement of each first treatment finger (30) (30a) (30b) is as described above. The opposite is true.

  Accordingly, the treatment force and treatment time applied to the affected area of the user by the first treatment fingers (30), (30a), and (30b) are different, and the first treatment fingers (30) (30a) are applied to the affected area. ) (30b) A variety of massage can be given.

  The angle restricting groove (16) with which the angle restricting protrusion (36) forming the angle restricting member (17) is engaged can be formed in the chassis (12). The angle restricting groove (16) extends in a direction parallel to the main shaft (21), and when the opening edge of the groove (16) interferes with each arm portion (31), as shown in the figure, It is desirable to form.

A shaft hole (38) for pivotally supporting a second treatment finger (40), which will be described later, is formed in the arm portion (31) of the central first treatment finger (30) on the tip side of the engagement hole (32). A bracket (37) is projected.
Further, a second guide (39) through which a second rod (19), which will be described later, is slidably fitted, is formed adjacent to the bracket (37).
The second guide (39) is formed such that the groove center is shifted in a parallel direction or a rotational direction with respect to a line connecting the center of the engagement hole (32) and the center of the shaft hole (38).

A second rod (19) whose one end abuts on the second eccentric cam (27) and the other end abuts on a contact (43) of a second treatment finger (40) described later slides on the second guide (39). It fits in. As the second rod (19), a flat plate having a rectangular cross section can be adopted. As shown in FIGS. 5 and 7, when the second rod (19) interferes with another member (for example, a shaft (42) described later). May form a taper at that portion.
When the stagnation shaft (20) is rotated, the rotation of the first treatment part (30) is restricted by the angle restricting member (17). Exercise. At this time, the arm portion (31) rotates coaxially with the engaging hole (32) fitted to the oblique shaft (25), so that the second eccentric cam (27) rotates by the eccentric rotation of the second eccentric cam (27). The second rod (19) in contact with 27) slides back and forth along the second guide (39). The reciprocating sliding movement of the second rod (19) serves as a power source for the swinging movement of the second treatment finger (40) described below.

The second treatment finger (40) is rotatably supported by the central first treatment finger (30).
As shown in FIGS. 1 to 4, the second treatment finger (40) is composed of a member having a length smaller than that of the first treatment finger (30).
The second treatment finger (40) has a recess (41) formed on the outer surface on the base end side, and a shaft (38) that fits into the shaft hole (38) of the arm portion (31) from the side surface of the recess (41). 42) is protruding.
The recess (41) is provided with a contact (43) that comes into contact with the distal end of the second rod (19) toward the proximal end.
The second treatment finger (40) has the shaft (42) fitted in the shaft hole (38) of the bracket (37) and is pivotally supported by the first treatment finger (30), and the contact (43) is the first treatment finger (40). Deployed to abut the tip of the two rods (19).

  The distal end of the second treatment finger (40) constitutes a second stagnation surface (44) facing the distal end pressing member (33) of the central first treatment finger (30). The second massaging surface (44) is a surface that pushes the shoulder from behind when the user's shoulder is squeezed, and the width of the second massaging surface (44) is similar to that of a human shoulder massage. In order to obtain an effect, it is desirable that the thumb is a little wider than the thumb of the hand.

  The second treatment finger (40) is shown in FIG. 5 so that the contact (43) is in close contact with the second rod (19) and the second rod (19) is in close contact with the second eccentric cam (27). Thus, it is desirable to urge the urging means (50) such as a spring toward the side away from the first treatment finger (30). This prevents the second rod (19) from wobbling or falling off, and transmits the eccentric rotation of the second eccentric cam (27) to the second treatment finger (40) through the second rod (19) without play. And it can convert into the rocking | fluctuation motion of a 2nd treatment finger (40).

As shown in FIG. 5 and FIG. 7, the second treatment finger (40) is moved back and forth by the rotation of the second eccentric cam (27). Oscillating movement approaching and moving away from.
When the second eccentric cam (27) rotates eccentrically and the second rod (19) moves in the second guide (39) by the second eccentric cam so as to protrude outward, the second treatment finger ( 40), the contact (43) is pushed out to the second rod (19), but the second treatment finger (40) is pivotally supported by the first treatment finger (30) by the shaft (42). As shown in FIG. 7, it swings around the shaft (42) in the direction approaching the first treatment finger (30).
Conversely, as shown in FIG. 5, when the second eccentric cam (27) further rotates, the second rod (19) follows the second eccentric cam (27) by the biasing force of the biasing means (50). The second treatment finger (40) swings away from the first treatment finger (30).
By repeating the above, the second treatment finger (40) performs a swinging motion that approaches and separates from the first treatment finger (30).

  As for the massage unit (10) having the above-described configuration, as shown in FIG. 10, the user receives the first treatment finger (30) (30a) (30b) on the upper side of the shoulder and the second treatment finger (40) on the back side. When the massage unit (10) is set so that it hits and the stagnation motor (14) is driven, power is transmitted to the stagnation shaft (20) via the speed reduction mechanism (15), and the stagnation shaft (20) rotates. . The stagnation shaft (20) rotates with the oblique shaft (25) provided on the inclined shaft portions (22) at both ends of the main shaft (21) tilted with respect to the main shaft (21), but attached to the oblique shaft (25). The pair of left and right first treatment fingers (30), (30a), and (30b) are prevented from rotating together with the oblique axis (25) by the angle restricting member (17). Swing to the left and right according to the inclination, approach and separate from each other. Thereby, the affected part of a user can receive a press massage.

  Further, since the second eccentric cam (27) is provided at a position eccentric to the oblique axis (25), as shown in FIGS. 5 and 7, the second eccentric cam (27) is moved away from the second guide (39). When the cam (27) is moved, the second rod (19) is retracted, and the second treatment finger (40) in contact with the second rod (19) is moved away from the first treatment finger (30), that is, The first treatment finger (30) (30a) (30b) and the second treatment finger (40) are swung in the opening direction.

  From this state, when the second eccentric cam (27) further rotates and moves in a direction approaching the second guide (39), the second rod (19) advances and the second rod (19) moves to the second treatment finger. By pushing forward (43) of (40), the second treatment finger (40) moves closer to the first treatment finger (30) (30a) (30b) around the axis (42), that is, The first treatment finger (30) (30a) (30b) and the second treatment finger (40) are swung in a direction in which the interval is narrowed.

As described above, the second treatment finger (40) approaches and separates from the first treatment finger (30), (30a), and (30b), so that the affected area of the user is pinched and massaged. This pinching operation includes a first treatment finger (30) (30a) (30b) having a tip pressing member (33) similar to four fingers of a human hand, and a second pinching surface having the same width as the human thumb. Since it is performed by the second treatment finger (40) having (44), it is possible to obtain a feeling as if a person is shouldering.
Further, during the pinching, the first treatment finger (30) (30a) (30b) swings left and right, and the second treatment finger pivotally supported by the first treatment finger (30) (30a) (30b) Since (40) also swings, you can experience a massage like receiving acupressure while picking the shoulder.

Since the first treatment finger (30) is directly supported by the oblique axis (25) without using the swing arm described in the prior art document, most of the force transmitted from the oblique axis (25) is obtained. It can act on the affected area without loss.
Further, since the second treatment finger (40) also receives a swinging force from the second eccentric cam (27) via the second rod (19) that slides, the transmitted force of the second treatment finger (40) is larger than the conventional force. Loss can be suppressed.
In addition, since the second treatment finger (40) also receives a swinging force from the eccentric cam (27) through the rod (19) that slides, the loss of the transmitted force is suppressed as compared with the conventional treatment finger (40). Can do. Moreover, since it is not influenced by the movement of the first treatment finger (30) (30a) (30b), the first treatment finger (30) (30a) (30b) and the second treatment are not affected by the load state. Can be pinched with fingers (40).
Accordingly, the first treatment finger (30) and the second treatment finger (40) do not need to be constructed as in the conventional manner, and can be made of resin or the like, and the first treatment finger (30). The number of parts for moving (30a), (30b) and the second treatment finger (40) can be reduced. Therefore, weight reduction, size reduction, and cost reduction of the massage unit (10) can be achieved.

By appropriately setting the amount of eccentricity of the second eccentric cam (27) to the oblique axis (25), the eccentric angle diameter, etc., the swing range of the second treatment finger (40), that is, the first treatment finger (30) It is also possible to change the pinching width of the pinching (30a) (30b) and the second treatment finger (40) and the timing of pinching.
The outer peripheral shape of the second eccentric cam (27) is circular in this embodiment. However, the second eccentric cam (27) approaches the first treatment finger (30) and the second treatment finger (40) by providing an elliptical shape or providing a straight portion. You can lengthen or shorten the time and provide a variety of massage massage.

As shown in FIGS. 9 and 10, the massage unit (10) of the present invention includes a resin cover (60) on the outer periphery and a cloth cover (61) on the treatment finger portion, and is a pillow-type massage machine. It can be used as or placed on the bed so that the affected part such as the shoulder can be massaged while the user P is lying down. It is also possible to receive a massage on the affected part such as the shoulder while the user P is sitting.
The massage unit (10) of the present invention can be provided on the backrest of a chair type massage machine so as to be movable up and down, and can be massaged from the shoulder of the user to the waist.

FIGS. 11 to 13 show an embodiment in which the second treatment fingers (40), (40), and (40) are arranged on all the first treatment fingers (30), (30a), and (30b), respectively. In addition, the same code | symbol as the said Example represents the same member.
Each first treatment finger (30), (30a), (30b) has a bracket (37) that pivotally supports the second treatment finger (40) and a second guide (39) through which the second rod (19) is slidably inserted. The second eccentric cam (27) is formed in three rows on the oblique line (25) on the extended line of the second guide (39). With such a configuration, the first treatment fingers (30), (30a), and (30b) and the second treatment fingers (40), (40), and (40) can be pinched more widely.

  14 to 16, the first treatment fingers (30), (30a) and (30b) are provided with a tip pressing member (33) swingably disposed on the arm portion (31), and the first treatment fingers (30) and (30a) are arranged. ) (30b) can be bent toward the second treatment finger (40) side in accordance with the rocking motion of (30b).

As shown in FIGS. 16 to 18, each first treatment finger (30), (30a), (30b) has a bracket (34) protruding from the tip of the arm portion (31), and the bracket (34) Is provided with a shaft hole (34a) for pivotally supporting the tip pressing member (33).
Further, a first guide (31a) is formed in the longitudinal direction from the engagement hole (32) to the oblique axis (25) in the arm portion (31) of the first treatment finger (30) (30a) (30b). The first guide (31a) is slidably fitted with a first rod (18) that presses the distal end pressing element (33).

  As shown in the drawing, the first eccentric cam (28) formed eccentrically with respect to the oblique shaft (25) is formed in the oblique shaft (25) portion with which the first rod (18) abuts. . The first rod (18) in contact with the first eccentric cam (28) slides back and forth along the first guide (18) by the eccentric rotation of the first eccentric cam (28). The reciprocating sliding motion of the first rod (18) serves as a power source for the swinging motion of the tip presser (33).

As described above, the tip pressing element (33) is a shaft that fits into the shaft hole (34a) of the bracket (34) provided in the arm part (31) of the first treatment finger (30) (30a) (30b). (Not shown) is formed, and is arranged so as to be swingable with respect to the first treatment fingers (30), (30a) and (30b).
Further, a contact (35) that abuts against the tip of the first rod (18) is provided.

  The tip pusher (33) is the same as in FIG. 5 so that the contact (35) closely contacts the first rod (18) and the first rod (18) contacts the first eccentric cam (28) closely. It is desirable to bias the arm portion (31) by a biasing means such as a spring (reference numeral (50) in FIG. 5). As a result, the tip pusher (33) and the first rod (18) are prevented from wobbling or falling off, and the eccentric rotation of the first eccentric cam (28) is pushed through the first rod (18) without any play. It can be transmitted to the child (33) and converted into a swinging motion of the tip pressing member (33).

When the kneading shaft (20) is rotated, the oblique shaft (25) is rotated, and the first treatment fingers (30), (30a) and (30b) are swung in the same manner as in the above embodiment, and the first treatment finger is rotated. (30) (30a) (30b) and the 2nd treatment finger (40) approach and separate.
At this time, the first eccentric cam (28) with which the first rod (18) is in contact also rotates eccentrically, and the first rod (18) is moved into the first eccentric cam (28) in the first guide (31a). When pushed and moved in the direction protruding outward, the tip pusher (33) is pushed by the contact (35) to the first rod (18), but the tip pusher (33) is pushed by the first treatment finger (30). As shown in FIGS. 15 and 18, it swings in the direction approaching the second treatment finger (40) around the shaft support (34a), as shown in FIGS. To do.
