  First, in the case of the prior art that receives a load from the auxiliary treatment element, in order to obtain a soft touch feeling, it is necessary to increase the contact area to the user, and a wide roller or a roller having a large diameter is required. For this reason, there exists a problem that the whole surrounding component including the treatment arm will become large. On the other hand, in the case of the prior art that receives a load on the support surface of the support frame, the support surface is fixed and does not follow movement in the front-rear direction of the treatment element (strength movement), so even in the strong mode in which the treatment element protrudes forward, There is a problem that the user receives the user on the support surface and cannot obtain a strong massage effect.

  An object of the present invention is to provide a chair type massage machine that can obtain a sufficient massage effect in the strong mode and can perform massage with a soft hit feeling in the weak mode without using a large-scale configuration. is there.

  The chair-type massage machine of the present invention has a treatment mechanism built in the backrest, and the treatment arm provided at the front end of the treatment-type arm massages the back of the user as the treatment arm swings. In the machine, the treatment mechanism is disposed below the treatment element and a strength switching mechanism capable of adjusting a massage intensity by changing a protrusion amount of the treatment element, and when the treatment element is retracted, And a support member that supports the substantially flat surface.

  According to the above configuration, the treatment mechanism is built in the backrest, and the pair of left and right treatment arms in the treatment mechanism swings in the width, front and rear, and up and down directions, so that the treatment element provided at the substantially distal end is treated. In a chair-type massage machine that performs treatment such as fir or tapping on the back of a person, the treatment mechanism is capable of adjusting the massage intensity by changing the amount of protrusion of the treatment element from the treatment mechanism, that is, the backrest. A switching mechanism is provided, and a support member that performs a retreat operation in conjunction with the advance / retreat operation of the treatment element is provided below the treatment element, and not only in the treatment element in the weak mode in which the treatment element is retracted. The back of the user is supported by the substantially flat surface of the support member.

  Therefore, since the support member moves backward in conjunction with the protrusion of the treatment element, the amount of strength can be increased, and in the strong mode, only the treatment element can be brought into contact with the back of the user to perform a strong massage. In particular, a large massage effect can be obtained from the shoulder to the neck of the user. On the other hand, without using a large-scale configuration such as a large-diameter roller, in the weak mode, massage can be performed with a soft touch feeling between the treatment element and the substantially planar support surface of the support member.

  Further, in the chair type massage machine of the present invention, the treatment arm is formed in a substantially U shape in a side view, and a substantially central portion thereof is swingably supported, and the treatment element is disposed at one end and the treatment element is disposed at the other end. The support members are respectively attached, and the strength switching mechanism adjusts the massage strength by swinging the treatment arm, and the treatment element side of the treatment arm is in a strong mode substantially perpendicular to the backrest surface. The treatment element protrudes from the backrest surface and the support member is retracted, and the line connecting the treatment element and the support member is in a weak mode in which the treatment element side of the treatment arm is substantially parallel to the backrest surface. It is characterized by being substantially parallel to the backrest surface.

  According to the above configuration, the support member retreats in a seesaw manner in conjunction with the protrusion of the treatment element, and the support surface of the treatment element and the support member is in substantially the same position in the weak mode, so there is no sense of incongruity due to a step, Massage can be performed with a soft touch.

  Furthermore, in the chair type massage machine of the present invention, the support member has a winding surface that is continuous with the substantially flat surface and is formed so as to wind the other end side of the treatment arm. It is characterized in that the treatment arm is formed in a cylindrical surface whose distance from the lower frame of the treatment mechanism is substantially constant with respect to the swing of the treatment arm.

  According to the above configuration, when the treatment element is attached to one end of the generally U-shaped treatment arm that swings as described above and the support member is attached to the other end, the support member is placed on the user side. When the treatment arm swings to switch from the weak mode that comes out to the strong mode that retreats, the support member is a plate-like member attached to the other end of the treatment arm. A foreign object may be sandwiched between the support member and the cylindrical member, and a cylindrical winding surface that is continuous from the substantially flat surface is formed on the support member. The distance between the winding surface and the lower frame is substantially constant, and the foreign object can be prevented from being caught.

  In the chair type massage machine of the present invention, an end edge portion of the substantially planar support member is chamfered in a curved shape.

  According to said structure, a softer massage can be implement | achieved, without making a user feel the local contact | feeling feeling by an edge.

  Furthermore, in the chair type massage machine of the present invention, the support member functions as a thermal unit that can give thermal stimulation to the user.

  According to said structure, it functions as a thermal part which can give a thermal stimulus to a treatment person by incorporating a heater in the said supporting member.

  Therefore, a treatment operation can be performed while giving a thermal stimulus to the user, and effective treatment can be performed by promoting blood circulation.

  Moreover, in the chair type massage machine of the present invention, the treatment element and the support member are formed to have substantially the same width, and the support member functions as a heating part that can give a thermal stimulus to the user. And

  According to said structure, the thermal stimulation by a support member and the treatment by a treatment element can be switched and given to substantially the same site | part by switching of massage intensity | strength.

  Furthermore, in the chair type massage machine of the present invention, the heating part has a built-in electric heater, and heating is started when the main power is turned on.

  According to said structure, thermal stimulation can be started rapidly (time until thermal stimulation is started can be shortened).

  As described above, the chair type massage machine of the present invention has a treatment mechanism built in the backrest, and the pair of left and right treatment arms in the treatment mechanism swings in the width, front and rear, and up and down directions. In a chair type massage machine in which the treatment element provided performs treatment such as fir action and tapping action on the back of the user, the intensity switching that allows the massage mechanism to adjust the massage intensity by changing the protruding amount of the treatment element It is provided with a mechanism, and a support member that performs a retreat operation in conjunction with the advance / retreat operation of the treatment element is provided below the treatment element, in the weak mode in which the treatment element is retracted, not only the treatment element, The back of the user is supported by a substantially flat surface of the support member.

  Therefore, the support member moves backward in conjunction with the protrusion of the treatment element, so that the amount of strength can be increased. In the strong mode, only the treatment element can be brought into contact with the back of the user to perform a strong massage. On the other hand, without using a large-scale configuration such as a large-diameter roller, in the weak mode, massage can be performed with a soft touch feeling between the treatment element and the substantially planar support surface of the support member.

  FIG. 1 is a perspective view of a chair type massage machine 21 according to an embodiment of the present invention, and FIG. 2 is a side view thereof. This massage machine 21 includes a seat portion 22 on which a user sits, a backrest portion 25 incorporating a treatment mechanism 24 including a treatment element 23 to be described later for performing upper body massage, an arm rest portion 26, and a lower leg portion And a leg holder 27 including an airbag for performing massage. There are some configurations such as an operation panel that are partially omitted.

  3 to 8 are views for explaining the treatment mechanism 24 in detail. FIG. 3 is a perspective view of the treatment mechanism 24 as seen from the front side. FIG. 4 is a perspective view of the treatment mechanism 24 as seen from the back side. FIG. 5 is a side view, FIG. 6 is a front view, FIG. 7 is a perspective view of the internal treatment element assembly 28 taken out, and FIG. 8 is a side view thereof. In addition, although the said treatment element 23 is comprised by left-right pair, in these figures, in order to make it easy to see, only the right treatment element is shown and the left treatment element comprised symmetrically is abbreviate | omitted.

  A pair of left and right drive shafts 32 and a guide shaft 33 protrude from the body frame 31 of the treatment mechanism 24, and slide in a guide groove (not shown) laid in the backrest portion 25. The treatment mechanism 24 can be moved up and down. Further, a gear 35 meshing with a rack rail (not shown) laid in the backrest portion 25 is attached to the drive shaft 32, and a motor (in the drawing, mounted on the right side portion of the main body frame 31). The worm and the gear housed in the gear box 39 are rotated and transmitted to the gear 35 through the drive shaft 32, and the treatment mechanism 24 is moved up and down in the backrest 25. It can be moved up and down in the direction to adjust the height and stretch the back.

  The treatment element assembly 28 is accommodated in the main body frame 31, and when the motor 36 provided on the side portion of the main body frame 31 rotates, the driving force is transmitted via a gear mechanism (not shown). Then, the treatment element assembly 28, which is transmitted to the gear 37 and supported by the main body frame 31 so as to be swingable around the shaft 38, swings. The treatment element 23 is pivotally supported at one end of a treatment arm 41 which is formed of a fir ball having an elastic surface and is formed in a substantially U shape in a side view.

  On the other hand, the substantially U-shaped treatment arm 41 has a portion 41a on the treatment element 23 side and a portion 41b on the support member 42 side connected by a nodal point 41c so that the treatment arm 41 can be opened and closed freely. When the motor 44 mounted on the child assembly 28 is rotated, the eccentric shaft 40 having a phase difference of 180 ° on the left and right is rotated like a crankshaft via a gear (not shown) and the link 48 attached thereto is connected to the treatment 48. The part 41a of the arm 41 is swung on the side opposite to the treatment element 23, thereby performing a tatting operation. In addition, when the motor 34 mounted on the lower part of the main body frame 31 is rotated, the width of the pair of left and right treatment arms 41 is changed in synchronization with each other via a gear or a clutch mechanism (not shown). As a result, the treatment element 23 performs a fir operation on the user.

  In the massage machine 1 configured as described above, it should be noted that in the present embodiment, the other end of the treatment arm 41 and below the treatment element 23 are made of resin or the like, and the back of the user. The support member 42 that supports the substantially flat surface 42a is attached. Then, as the treatment arm 41 swings about the shaft 38 in the substantially central portion, as shown in FIGS. 3A and 5A, the portion 41a on the treatment element 23 side of the treatment arm 41 is moved. As shown in FIGS. 3 (b) and 5 (b), the massage strength can be adjusted by standing up substantially vertically from a state substantially parallel to the backrest 25, and the motor 36, gear mechanism The shaft 38 and the like constitute an intensity switching mechanism.

  In this way, the support member 42 is retracted in a seesaw manner in conjunction with the protrusion of the treatment element 23, so that the amount of strength can be increased compared to the case where the support member 42 is fixed. As a result, in the strong mode in which the treatment element 23 protrudes and the portion 41a of the treatment arm 41 is substantially perpendicular to the backrest portion 25, only the treatment element 23 can be brought into contact with the back of the user to perform a highly stimulating massage. In particular, a large massage effect can be obtained from the shoulder to the neck of the user.

  On the other hand, in the weak mode in which the treatment element 23 is retracted and the portion 41a of the treatment arm 41 is substantially parallel to the backrest 25, the treatment element 23 and the support member 42 are both in contact with the back of the user. Since the support surfaces of the treatment element 23 and the support member 42 are substantially in the same position (the line 43 connecting them is substantially parallel to the backrest portion 25), there is no sense of incongruity due to a step, and a soft (slow stimulation) contact feeling Can be treated. Further, when the treatment mechanism 24 is moved up and down by height adjustment or the like, the local support of the treatment element 23 may cause pain, whereas the support member 42 adds support on the substantially flat surface 42a. Thus, such a problem can be suppressed. Furthermore, since the support member 42 is not in a roller shape, the contact area for supporting the user can be increased without increasing the size of the components.

  Also, it should be noted that the support member 42 is a winding surface that is continuous with the substantially flat surface 42a and is wound around the lower side of the generally U-shaped treatment arm 41 as shown in an enlarged view in FIG. 42b, and the winding surface 42b is formed in a cylindrical surface such that the distance W1 to the lower frame 31a of the treatment mechanism 24 is substantially constant with respect to the swing of the treatment arm 41. This is because the treatment element 23 is attached to one end of the generally U-shaped treatment arm 41 that swings as described above, and the support member 42 is attached to the other end when the support member 42 is attached to the other end. When the treatment arm 41 swings in order to switch from the weak mode appearing to the reverse to the strong mode, as shown by a support member 42 'in FIG. This is because there is a possibility that the foreign object 44 may be sandwiched between 42y and the lower frame 31a.

  Therefore, a cylindrical winding surface 42b continuous from the substantially flat surface 42a is formed on the support member 42, and the distance W1 between the winding surface 42b and the lower frame 31a when the support member 42 moves backward is made substantially constant. Thus, the foreign object can be prevented from being caught.

  Further, it should be noted that the edge portion in the left-right direction of the support member 42 is chamfered in a curved shape (R = 15 to 20 mm) as indicated by reference numeral R in FIG. This makes it possible to realize a softer massage without causing the user to feel a local hit feeling due to the edge.

  It should also be noted that the support member 42 has a built-in thermal part 51 that can give a thermal stimulus to the user. For example, as shown in FIG. 9, the heating portion 51 is screwed and fixed to the opening 42 c formed in the substantially flat surface 42 a of the support member 42 made of resin or the like with screws 45. The heating portion 51 is formed by attaching an electric heater 52 to a bracket 53 made of a metal having good thermal conductivity, and the flange portion of the bracket 53 is screwed and fixed to the support member 42 by the screw 45.

  Therefore, a treatment operation can be performed while giving a thermal stimulus to the user, and effective treatment can be performed by promoting blood circulation. Further, as shown in FIGS. 3 (a) and 5 (a), a thermal stimulus is given to the user in a weak mode in which the treatment element 23 is retracted, as shown in FIGS. 3 (b) and 5 (b). It is possible to prevent the thermal stimulus from being applied in the strong mode in which the treatment element 23 is protruded. Accordingly, it is possible to promptly switch the treatment operation of giving or not giving a thermal stimulus, such as performing a thermal stimulus to the user in the initial stage and then performing a treatment without the heat.

  Furthermore, as shown in FIG. 6, by forming the treatment element 23 and the support member 42 to have substantially the same widths W2 and W3, the support member 42 is provided at substantially the same site by switching the massage strength as described above. It is possible to switch between the thermal stimulation by and the treatment by the treatment element 23.

The changing reclining mechanism 69 is driven to enable a massage operation. The massage mechanism 68 and the reclining mechanism 69 include a switch element that operates in response to a control signal from the main body side control circuit 64, and receives a voltage from the commercial power source or a voltage obtained by appropriately rectifying and stepping down the voltage. The switch element is ON / OFF controlled and applied to the motors 34, 36, 44, thereby performing the massage operation as described above.

  The operation state of each part during the massage is detected by various sensors 71 to 74, and the main body side control circuit 64 displays the progress state or abnormality of the massage on the display unit 67 via the operation unit side control circuit 65. To do. The sensor 71 detects the treatment element (fir ball) 23, that is, the vertical position of the treatment mechanism 24, the sensor 72 detects the width position of the treatment element 23, and the sensor 73 detects the strength position of the treatment element 23 (see FIG. ) And FIG. 3B, and the swing angle of the treatment arm 41 as shown in FIGS. 5A and 5B), and the sensor 74 detects the rotational speed of the treatment element 23. The detection result is fed back to the control of the motors 34, 36, 44 and the like, and the massage operation as described above becomes possible according to a predetermined course menu.
