Description

  The present invention relates to a chair type massage machine that includes a leg rest and can treat a calf and a sole.

  2. Description of the Related Art Conventionally, there has been known a chair type massage machine including a seat portion on which a user is seated and a leg rest portion for performing massage on a lower leg portion of the user in a seated state. The leg rest of these chair type massage machines has a structure in which a calf of a user is fitted in a concave groove formed in the leg rest, and massage is applied to the calf by a treatment means such as an air bag. However, there was a problem that massage cannot be given to the soles. Therefore, in order to solve the above problem, a chair type massage machine having a leg rest part composed of a calf holding part for holding the calf's calf and a sole holding part for holding the sole of the user is proposed. (See Patent Document 1), which enables more effective leg massage.

However, the chair type massage machine having the above-mentioned leg rest has the following problems because the body shape of the user is various. That is, for example, when the user has a short body shape below the knee, the sole of the user who is in the sitting state does not reach the sole holding portion of the leg rest, and the sole can be massaged. If the patient has a long body below the knee, the sitting posture with the sole holding the sole is very cramped, and the leg resting part is on the top side. When it is rotated so as to be lifted, there is a problem in that there is a risk that the area around the knee joint of the user is pressed and feels pain and the tendon is damaged.

  This invention is invented in view of the said problem, Comprising: The chair type massage machine which can change the distance from a seat part to a sole holding part smoothly and easily according to a user's body shape is provided. It is an object to do.

In order to solve the above problems, the chair type massage machine according to the present invention holds the seat 2 where the user is seated, the calf holding part 7 that holds the calf of the user, and the sole of the user. The leg rest part 6 having the sole holding part 8, the connection support part 19 that is supported to be pivotable up and down in front of the seat part 2, and the leg support part 6 with respect to the connection support part 19 The slide mechanism 27 that is movably connected in the direction of the toe of the foot, the urging means 32 that is arranged in parallel on the left and right sides and urges the leg rest 6 in the direction approaching the seat 2, and the leg rest 6 are connected. A chair type massage machine comprising a tilt prevention mechanism 31 for preventing tilting beyond a predetermined allowable amount with respect to the support part 19, wherein the connection support part 19 extends from both the left and right sides in a sliding direction. A fixed connection between the pair of side pipes 23 and the left and right side pipes 23 24, and the slide mechanism 27 is slidably fitted to the slide support member 26 fixed to the center of the connection plate 24 of the connection support portion 19 in the left-right direction. The urging means 32 is arranged on both the left and right sides sandwiching the central slide mechanism 27, and the tilt prevention mechanism 31 is connected to the connection support portion 19. The tilt prevention mechanism is formed by the left and right side pipes 23 and the tilt prevention members 18 fixed to the left and right ends of the leg rest 6 so as to surround the left and right side pipes 23 at a predetermined interval. 31 is provided so as to be located on both the left and right sides of the slide mechanism 27 and the biasing means 32 .

  In the chair type massage machine configured as described above, a user who is seated on the seat 2 holds the calf and the sole of the leg on the calf holding part 7 and the sole holding part 8 of the leg rest 6. In addition to being able to perform massage, the posture of the leg rest part 6 is changed by the rotation of the connection support part 19, or the leg rest part 6 is slid by the slide mechanism 27 to be lifted from the seat part 2. The distance to the holding unit 8 can be changed. And by providing the urging means 32, the user pushes the sole holding part 8 against the urging force of the urging means 32 or uses the urging force of the urging means 32. The leg rest 6 can be easily slid by lowering the sole holder 8 and the urging means 32 is arranged in the left and right, so that the left / right balance of the leg rest 6 is good when sliding. Since the load per one urging means 32 can be small, each urging means 32 can be formed thin and the mechanism between the seat 2 and the leg rest 6 can be made compact. .

Here, since the urging means 32 is arranged side by side on both the left and right sides of the center slide mechanism 27, the urging force is exerted on both the left and right sides of the slide mechanism 27 located at the center. The leg rest 6 can be slid smoothly and easily while maintaining a good balance.

Furthermore , in the chair type massage machine according to the present invention , the leg resting part 6 is tilted beyond the predetermined allowable amount with respect to the connection support part 19 on both the left and right sides sandwiching the slide mechanism 27 and the biasing means 32. comprising a tilt prevention mechanism 31 for preventing and sliding mechanism 27 in a central position, situated biasing means 32 on the left and right sides, further since anti-falling mechanism 31 on the left and right sides are structured to position the leg can ensure smooth sliding and prevent the leg rest portion 6 by tilting prevention mechanism 31 of the left and right sides are tilted largely when a large offset load on one of the left and right mounting portion 6 has occurred. In addition, the anti-tilt mechanism 31 is arranged on both the left and right sides sandwiching the slide mechanism 27 and the tension spring 33. In this structure, the distance between the slide mechanism 27 arranged at the center and the anti-tilt mechanisms 31 on both sides is small. Since it is set to the largest value, even if there is a slight variation in the accuracy of the parts constituting the tilt prevention mechanism 31, the variation hardly affects the accuracy of the entire tilt prevention mechanism 31. That is, with the simple structure described above, the leg rest 6 can be slid more smoothly and easily while maintaining a good left / right balance.

  The chair type massage machine of the present invention has an effect that the distance from the seat portion to the sole holding portion can be changed smoothly and easily according to the body shape of the user.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. In FIG. 7, the whole chair type massage machine of an example in embodiment of this invention is shown. The chair type massage machine of this example can be tilted to the rear of the seat 2 so that the user can sit on the seat 2 and the user who is seated on the seat 2 leans his back. The provided backrest part 3, the elbow rest part 4 provided in the right and left both sides of the seat part 2 in order that the user who is seated in the seat part 2 may put an arm, and the support leg which supports each said parts 2-4 A leg rest 6 for holding a lower knee part (that is, from a calf part to a sole part) of a leg part by a user who is seated on the seat part 2 on a massage machine main body 1 mainly composed of a part 5. It is connected so that the posture can be freely changed. In addition, each direction, such as up and down, left and right, and front and rear, used in the text is based on a direction viewed from the side of the user who is seated on the seat 2.

  The leg rest portion 6 of this example has a calf holding portion 7 that holds and holds the calf portion of the leg portion of the user, and a sole that hits and holds the sole portion of the leg portion of the user The holding portion 8 is integrally formed. The leg rest portion 6 is formed with a pair of left and right concave grooves 9 into which the entire lower knee portion of the leg of the user is fitted, and the base end side and the front surface of the concave groove 9 extending in the foot tip direction of the leg portion. The leg portion of the user is provided so as to be freely accessible through the open portion. Here, in this example, the portion formed on the front end side of the concave groove 9 is the groove portion of the sole holding portion 8 into which the sole, the toe, and the ankle portion of the user fit, and the sole holding By driving a treatment means (not shown) such as an air bag arranged on the inner wall of the groove portion of the portion 8, massage is performed on the sole, the toe, and the ankle portion. The portion of the concave groove 9 that is proximal to the groove portion of the sole holding portion 8 is the groove portion of the calf holding portion 7 into which the calf portion of the user is fitted, and the calf holding portion 7 The calf portion is massaged by driving a treatment means (not shown) such as an air bag disposed on the inner wall of the groove portion. In addition, the base end side of the above-mentioned concave groove 9 is a side close to the seat portion 2 among both longitudinal ends of the concave groove 9, and the distal end side of the concave groove 9 is the longitudinal direction of the concave groove 9. It is a side away from the seat part 2 among both ends, and the front side of the concave groove 9 is a side facing forward when the tip of the leg rest part 6 is directed downward.

  As shown in FIG. 1 and the like, the leg mounting portion 6 includes a base pipe 10 that holds the bottom wall portions of both concave grooves 9, and a reinforcement that stands from the base pipe 10 and holds the left and right side wall portions of each concave groove 9. A pipe 11 and a reinforcing plate 12, and a foot holding member 13 that is provided upright from the base pipe 10 and holds a side wall portion on the tip side of each concave groove 9 (that is, a portion where the sole touches in the sole holding portion 8). The main frame is formed by forming a whole frame and fitting the cover 14 on the frame. In this example, by using a sheet metal for the sole holding member 13, it is thin but is strong enough to withstand the load received from the sole portion of the user. Under the limitation, the sole holding portion 8 can be formed thin to secure the length region of the calf holding portion 7.

  At the center portion in the left-right direction of the leg rest portion 6, it extends in the foot tip direction of the leg portion (that is, in the longitudinal direction of the concave groove 9) so as to span between the base pipe 10 and the sole holding member 13. The slide member 15 is fixed. The slide member 15 is slidably fitted in a foot support direction (hereinafter referred to as a slide direction) of a leg portion and a slide support member 26 fixed to a connection support portion 19 to be described later, thereby forming a slide mechanism 27. Is. Further, an adjustment member 17 is fixed to the leg rest 6 so as to extend in parallel to the slide member 15, that is, in the slide direction, and has a large number of fitting holes 16 arranged in the slide direction. The slide fixing mechanism 30 is formed by providing the movable pin 29 of the positioning member 28 fixed to the support portion 19 so as to be fitted into the fitting hole 16. Furthermore, a pair of anti-tilt members 18 having a U-shaped cross section are fixed to the left and right end portions of the leg rest 6 so that the opening sides face each other. The tilt prevention mechanism 31 is formed by surrounding the 19 side pipes 23. The mechanisms 27, 30, 31 will be described in detail again.

  The connection support portion 19 is supported by the massage machine body 1 so as to be vertically movable at a position in front of the seat portion 2 and connects the leg rest portion 6 so as to be able to advance and retreat in the slide direction. By using 19, the leg rest 6 is structured to be connected to the massage machine body 1 so as to be rotatable and slidable. The connection support portion 19 includes a pipe 20 extending in the left-right direction, a support plate 22 that is fixed to both left and right ends of the pipe 20 and has a rotary bearing portion 21 open at one end thereof, and both left and right sides of the pipe 20. A pair of side pipes 23 extending so as to extend in the sliding direction and a pair of connecting plates 24 fixed so as to be bridged between the side pipes 23 on both the left and right sides constitute a main body.

  A resin-made slide support member 26 having a fitting groove 25 extending in the slide direction is fixed to the distal-side connection plate 24 of the pair of connection plates 24 arranged in the slide direction. The bottom portion of the slide member 15 is slidably fitted into the fitting groove 25 of the slide support member 26 so that the leg mounting portion 6 slides in the sliding direction with respect to the connection support portion 19. The slide mechanism 27 is formed so as to be freely reciprocated. Similarly, a positioning member 28 having a movable pin 29 that can be protruded and retracted by a remote operation using a wire (not shown) is fixed to the connecting plate 24 on the distal end side. By providing the movable pin 29 in a protruding state so as to be fitted into any one of the plurality of fitting holes 16 arranged in a row, an arbitrary selected from slide amounts set in a plurality of stages is provided. A slide fixing mechanism 30 for fixing the leg rest 6 with a slide amount is formed.

  Furthermore, a pair of side pipes 23 arranged in parallel at both the left and right ends of the connection support portion 19 and a pair of anti-tilt members 18 fixed to the left and right end portions of the leg rest 6 so as to surround each side pipe 23. The tilt prevention mechanism 31 is formed to prevent the leg rest 6 from tilting with respect to the connection support 19 beyond a predetermined allowable amount. The tilt prevention member 18 is formed slightly larger than the outer shape of the side pipe 23 so as to maintain a predetermined distance from the side pipe 23, and is usually provided so as not to contact the side pipe 23.

  A pair of left and right coiled tension springs 33 are interposed between the connection support part 19 and the leg rest part 6 as a biasing means 32 for biasing the leg rest part 6 in a direction approaching the seat part 2. I am letting. The tension spring 33 is constructed between the pipe 20 located on the proximal end side of the connection support portion 19 and the sole holding member 13 located on the distal end side of the leg mounting portion 6. Since the same thing is arrange | positioned in the symmetrical position of the both right and left sides which pinch | interpose, the left-right balance is maintained and the smooth slide of the leg mounting part 6 is ensured.

  The connection support portion 19 has a rotation shaft extending in the left-right direction provided at the front position of the seat portion 2 of the massage machine body 1 on the rotation bearing portions 21 of the support plates 22 provided at the left and right ends of the base end side (see FIG. (Not shown) is pivotably fitted so that the front end is lowered and substantially perpendicular to the seat surface of the seat 2 and the front end is lifted and substantially parallel to the seat surface of the seat 2. In such a horizontal posture, it is connected so as to be rotatable in the vertical direction around the rotation axis. Although a mechanism for controlling the posture of the connection support portion 19 is not particularly illustrated, it is preferable to use an elastic support means such as a motor or a link driven by air.

  Thus, in the chair type massage machine having the above-described configuration, the user who is seated on the seat portion 2 of the massage machine main body 1 places the lower knee portions of his / her left and right leg portions on the pair of left and right concave grooves 9 of the leg rest portion 6. By fitting each into the inside, the sole portion is applied to the inner bottom surface of the groove portion of the sole holding portion 8 formed on the distal end side of the leg mounting portion 6 to hold the sole portion, The calf part is fitted into the groove part of the calf holding part 7 formed on the end side to hold the calf part, and the treatment means arranged on the inner wall of the groove part of the sole holding part 8 is driven to drive the foot. Massage can be applied to the calf part by driving the treatment means disposed on the inner wall of the groove part of the calf holding part 7 while massaging the back part, the toe, and the ankle part.

  When the posture of the leg rest portion 6 is to be changed, the connection support portion 19 may be rotated in the vertical direction around the rotation shaft arranged in front of the seat portion 2 of the massage machine body 1. By rotating the leg rest part 6 via the connecting support part 19, the leg rest part 6 is lowered so that the front end side is lowered and substantially perpendicular to the seating surface of the seat part 2, and the front end side is lifted up and seated. It can be moved to any posture between a horizontal posture that is substantially parallel to the seating surface of the section 2.

  When the slide position of the leg rest 6 is to be changed, the projecting movable pin 29 that is normally fitted in one of the fitting holes 16 of the adjusting member 17 is first remotely operated. Thus, the positioning member 28 is immersed, and the fitting of the movable pin 29 with the fitting hole 16 is released. And after changing the sliding amount of the leg mounting part 6 with respect to the connection support part 19 via the slide mechanism 27, the movable pin 29 is protruded, and the fitting hole different from the fitting hole 16 previously fitted. 16, and the leg mounting portion 6 may be fixed to the connection support portion 19 again with the changed slide amount.

  The slide amount is changed as follows. That is, for example, when the user is trying to increase the slide amount toward the distal end side of the leg rest 6 because the user has a long body shape below the knee, the user releases the fitting of the movable pin 29. Then, the footrest portion 6 may be slid to the distal end side against the tensile force of the tension spring 33 by pushing the sole portion of the foot that contacts the sole holding portion 8 toward the distal end side. Further, for example, when the user is trying to reduce the sliding amount toward the distal end side of the leg rest portion 6 because the user has a short body shape below the knee, the leg can be removed if the user releases the fitting of the movable pin 29. The mounting portion 6 is slid toward the proximal end side by the tensile force of the tension spring 33, and thus the leg mounting portion 6 can be pulled down to the side approaching the seat portion 2.

  Here, since a pair of tension springs 33 are provided at equal intervals on both the left and right sides sandwiching the slide mechanism 27, the leg rest 6 can be smoothly slid while maintaining the left and right balance. Further, since there are a plurality of tension springs 33, the tension force required for each tension spring 33 can be small, and therefore the tension spring 33 can be set thin. By setting the tension spring 33 arranged in a mechanism for connecting the massage machine body 1 and the leg rest part 6 between the massage machine body 1 and the leg rest part 6, the inside of the concave groove 9 of the leg rest part 6 from the massage machine body 1 is set. Since the distance to the bottom surface can also be set short, it becomes easy for the user to hold the leg portion in the sitting state.

  Even when the balance is maintained by the tension spring 33, if a large unbalanced load is generated on the left or right side of the leg resting portion 6, the leg resting portion 6 is greatly tilted and caught on the slide. However, the leg mounting portion 6 of the present example includes the anti-tilt member 18 that surrounds the side pipes 23 at both the left and right end portions of the connection support portion 19 from the outside with a predetermined interval. Therefore, before the footrest 6 tilts beyond the predetermined allowable amount with respect to the connection support 19, the tilt prevention member 18 hits the side pipe 23 of the connection support 19, so that the slide is caught. The leg mounting part 6 is structured to prevent excessive tilting.

  The tilt prevention member 18 has a structure arranged on both the left and right sides sandwiching the slide mechanism 27 and the tension spring 33. With this structure, the slide mechanism 27 arranged in the center and the tilt prevention members 18 on both sides are arranged. It is possible to set the distance between the largest. As a result, the predetermined distance to be held between the tilt prevention member 18 and the side pipe 23 can also be set to be relatively large, and therefore there is some variation in the component accuracy and mounting accuracy of the tilt prevention member 18. Even if it exists, this dispersion | variation becomes difficult to affect the precision of the whole tilt prevention mechanism 31, and the smooth slide of the legrest part 6 is ensured.

  In the present example, the calf holding part 7 and the sole holding part 8 are integrated as the leg rest part 6, but the calf holding part 7 and the sole holding part 8 are not limited to this. It may be a formed structure. Further, the tension springs 33 may be provided in plural on the left and right instead of one on each of the left and right.
