  2. Description of the Related Art Conventionally, there is known a chair type massage machine including a seat portion on which a user is seated and an ottoman that holds a leg portion of the user in a seated state (see Patent Document 1). The ottomans of these chair type massage machines have a structure in which a leg portion of a user is fitted in a concave groove formed in the ottoman, and massage is applied to the leg portion using a treatment means such as an airbag. ing. However, the chair type massage machine having the ottoman has a problem that the treatment means of the ottoman cannot be applied to a desired treatment site because the body shape of the user is various.

  Therefore, in the course of reaching the present invention, the present inventors have a connecting support portion that is supported to be pivotable up and down in front of the seat portion, and the ottoman in the direction of the foot of the user with respect to the connecting support portion A chair type massage machine comprising a slide mechanism that is connected in a predetermined sliding direction along the sliding direction and a slide fixing mechanism that fixes the ottoman to the connection support portion with an arbitrary slide amount has been considered. The slide fixing mechanism fixes a fixing member having a large number of locking holes to the ottoman side, and a movable pin that can be protruded and retracted to the connection support portion side. The movable pin is attached to the fixing member. This is a structure that fits into one of the locking holes.

According to the above configuration, the distance between the ottoman and the seat can be freely set according to the body shape of the user, and the ottoman can be reliably fixed at the set distance. However, in the above-described slide fixing mechanism using a movable pin that can be freely retracted, especially when the ottoman is loaded, the movable pin is smoothly inserted and removed from the locking hole of the fixing member to adjust the slide. There was a problem that it was sometimes difficult to do.
JP 2002-238963 A

  The present invention has been invented in view of the above problems, and provides a chair type massage machine capable of fixing an ottoman with an arbitrary slide amount and capable of smoothly and reliably adjusting the slide of the ottoman. This is a problem.

  In order to solve the above-mentioned problems, the chair type massage machine according to the present invention is moved up and down in front of the seat part 2 where the user is seated, the ottoman 6 holding the leg part of the user, and the seat part 2. A connecting support portion 19 that is rotatably supported, a slide mechanism 27 that connects the ottoman 6 to the connecting support portion 19 so as to be able to advance and retreat in a predetermined sliding direction, and the ottoman 6 with an arbitrary slide amount. The slide-type massage machine includes a slide-fixing mechanism 30 that is fixed to the ottoman 6. The slide-fixing mechanism 30 is fixed to the ottoman 6 side, and a plurality of locking grooves 16 are arranged in a row along the sliding direction. A member 17, a stopper 29 which is rotatably installed on the side of the connection support portion 19 and can be fitted in any locking groove 16 of the fixing member 17, and a biasing force which biases the stopper 29 in the fitting direction. They are assumed that was formed by the root 41.

  By using the chair type massage machine having the above-described configuration, the user who is seated on the seat 2 can perform the massage while holding the legs on the ottoman 6, and the connection support 19 can be rotated. It is possible to change the posture of the ottoman 6, or to slide the ottoman 6 via the slide mechanism 27 to change the distance from the seat 2, and to fix the ottoman 6 by the slide amount by the slide fixing mechanism 30. It is. When the sliding amount of the ottoman 6 is changed, the rotary stopper 29 only needs to be put in and out of the locking groove 16 by its rotation, so that the slide adjustment is smoothly performed even when a load is applied to the ottoman 6. Is to be done.

Further, in the chair type massage machine of the present invention, a load applied to the ottoman 6 from the inside of the locking groove 16 toward the sliding direction is applied to the inner surface of the fixing member 17 that contacts the stopper 29 of the locking groove 16. An inclined surface 47 for converting the stopper 29 into a pushing force is formed . Therefore , while the load is small, the ottoman 6 can be fixed by the slide amount, and the slide amount can be changed by automatically releasing the ottoman 6 from being slid only when the load exceeds a certain level.

Furthermore, in the chair type massage machine of the present invention, the locking piece 42 is in the state where the locking piece 42 of the stopper 29 is inserted from the side on the inner surface of the locking groove 16 of the fixing member 17. An inclined surface 47 is formed at a portion where the surface 42b opposite to the seat portion 2 of the first contact portion 2 comes into contact so as to increase the distance from the locking piece 42 as the side opening of the locking groove 16 is approached. The load applied to the ottoman 6 in the sliding direction approaching the seat portion 2 side is converted into a force for pushing the stopper 29 out of the locking groove 16 . Therefore , when the user puts the weight on the tip of the ottoman 6 with the lower end of the ottoman 6 being in contact with the floor, the ottoman 6 is directed toward the sliding direction approaching the seat 2 side. After the stopper 29 is pushed out of the locking groove 16 to release the locking due to the load being applied, the ottoman 6 is inserted into the locking groove 16 at a position close to the seat portion 1 by one step. It becomes. That is, since the ottoman 6 automatically changes the slide amount toward the side approaching the seat 2, the danger that the entire massage machine is lifted and moved around the ground contact point with the floor surface is prevented.

  The chair type massage machine of the present invention has an effect that the ottoman can be fixed with an arbitrary slide amount, and the slide adjustment of the ottoman can be performed smoothly and reliably.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. In FIG. 4, 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 2 sits 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 Changing the posture of the ottoman 6 for holding the lower knee part of the leg part (that is, from the calf part to the sole part) on the massage machine body 1 which is mainly composed of the part 5 and the seat part 2 It is connected so that it can be freely changed and the slide amount can be 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 sitting on the seat 2.

  The ottoman 6 is formed with a pair of left and right concave grooves 9 into which the entire lower knee part of the leg of the user is fitted, and the base end side and the front side of the concave groove 9 extending in the foot tip direction of the leg part. The leg portion of the user is provided so as to be freely accessible through the open portion. Here, the portion formed on the front end side of the concave groove 9 is a groove portion of the sole holding portion 8 into which the sole, the toe, and the ankle portion of the user fit, By driving a treatment means (not shown) such as an air bag arranged on the inner wall of the groove portion, massage is performed on the sole, toe, and ankle portion. A portion of the concave groove 9 closer to the base end side than the groove portion of the sole holding portion 8 is a groove portion of the calf holding portion 7 into which the calf portion of the user is fitted, and the groove of the calf holding portion 7 Massage is applied to the calf portion by driving treatment means (not shown) such as an air bag disposed on the inner wall of the portion. In this example, the calf holding part 7 and the sole holding part 8 are integrated as the ottoman 6 as described above. However, the calf holding part 7 and the sole holding part 8 are separately provided. It may be a formed structure.

  As shown in FIG. 5, the ottoman 6 is connected to the massage machine body 1 via a connection support portion 19 so as to be rotatable and slidable. The connection support portion 19 is supported by the massage machine body 1 so as to be rotatable in the vertical direction at the front position of the seat portion 2 (see the arrow C in the figure), and the ottoman 6 is a predetermined slide along the toe direction. It is connected in such a way that it can move forward and backward. The sliding direction is a direction in which the ottoman 6 moves away from or approaches the seat portion 2 side. Therefore, in the following, the sliding direction away from the seat portion 2 side is particularly referred to as the sliding direction A, and the sliding direction approaching the seat portion 2 side is particularly defined. Let it be the slide direction B.

  FIG. 1 shows a state where the ottoman 6 and the connection support portion 19 connected to the back side thereof are viewed from the connection support portion 19 side. As shown in the figure, the connection support portion 19 includes a pipe 20 extending in the left-right direction, a pair of support plates 22 fixed to both left and right ends of the pipe 20 and having support bearings 21, and extending in the sliding direction from the left and right sides of the pipe 20. The pair of side pipes 23 extending in this manner and the pair of connecting plates 24 fixed so as to be bridged between the left and right side pipes 23 constitute a main body.

  As shown in FIG. 1, the ottoman 6 includes a base pipe 10 that holds the bottom portion of the bottom, a reinforcing pipe 11 that is erected from the base pipe 10 and holds the side wall portions of the concave grooves 9, and a reinforcing pipe. 11 and the sole holding member 13 that holds the portion of the groove 9 that touches the tip of the bottom of the groove 9 and forms a whole frame, and the cover 14 is fitted onto the frame to form the main body. Yes. A slide member 15 extending in the direction of the foot of the leg is fixed to the central portion of the ottoman 6 in the left-right direction. The slide member 15 is slidably fitted to a slide support member 26 (see FIG. 3) fixed to the connection plate 24 of the connection support portion 19 to form a slide mechanism 27.

  Further, a pair of anti-tilt members 18 having a U-shaped cross-section are fixed to the left and right ends of the base pipe 10 of the ottoman 6 so that the opening sides face each other. By being positioned so as to surround the 19 side pipes 23, the ottoman 6 is prevented from tilting in the left-right direction with respect to the connection support portion 19. Further, a pair of left and right coiled tension springs 33 are provided between the connection support portion 19 and the ottoman 6 as urging means for urging the ottoman 6 toward the sliding direction B approaching the seat portion 2 side. Is interposed.

  The connection support portion 19 includes support bearings 21 of support plates 22 provided at the left and right ends of the pipe 20 on the proximal end side, and a support extending in the left-right direction provided at the front position of the seat portion 2 of the massage machine body 1. By fitting the shaft 35 in a freely rotatable manner, a vertical posture in which the tip end side is lowered and substantially perpendicular to the seat surface of the seat portion 2 is lifted, and the tip end side is lifted to be substantially parallel to the seat surface of the seat portion 2. Such a horizontal posture is connected so as to be rotatable in the vertical direction around the support shaft 35. 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.

  The ottoman 6 of this example has a rack-like fixing member that extends in parallel to the slide member 15, that is, in the sliding direction, and has a large number of locking grooves 16 arranged in one side along the sliding direction. The main body of the slide fixing mechanism 30 is formed by providing a stopper 29 that is rotatably installed on the connection support portion 19 so as to be freely fitted in an arbitrary locking groove 16 (FIG. 2). reference). As shown in FIG. 2B, the locking groove 16 has a side opening 16a side wider than the groove bottom 16b side.

  The stopper 29 is rotatably installed around the shaft 40 on the front side of the connecting plate 24 on the distal end side of the pair of connecting plates 24, and an urging spring 41 is connected to one end of the shaft 40. At the other end of the shaft 40, a flat plate-like locking piece 42 (shaded portion in the figure) and a pulling piece 43 project. The locking piece 42 is a portion that is inserted into the locking groove 16 of the fixing member 17 from the side, and the biasing force of the biasing spring 41 that is a tension spring causes the stopper 29 to move in the insertion direction (in the drawing). (B) direction). A wire 44 for pulling the stopper 29 in a direction opposite to the insertion direction (b in the figure) is connected to the pulling piece 43 located adjacent to the locking piece 42, and the seat 2 of the massage machine main body 1 is connected to the pulling piece 43. The wire 44 is provided so as to be pulled by a rearward pulling operation of an adjusting lever 45 disposed between the elbow rest portion 4.

  In addition, the inner surface of each locking groove 16 of the fixing member 17 that is in contact with the flat plate surface 42a facing the seat 2 side of the locking piece 42 in the fitted state is locked in parallel with the flat plate surface 42a. The surface 46 is formed, and the inner surface of each locking groove 16 that is in contact with the flat plate surface 42b facing the side opposite to the seat 2 of the locking piece 42 in the fitted state is opposed to the flat plate surface 42b. An inclined surface 47 inclined by an angle θ is formed. Since the inclined surface 47 is inclined to increase the distance from the locking piece 42 as it approaches the side opening 16a side, a load is applied to the ottoman 6 toward the sliding direction B approaching the seat 2 side. If this is the case, this load is converted into a force that pushes the locking piece 42 laterally out of the locking groove 16 through the inclined surface 47 of the fixing member 17 fixed to the ottoman 6 side, so that the stopper 29 is shown in FIG. By rotating in the middle direction, the locked state with the fixing member 17 is automatically released. The stopper 29 after being released is inserted into the locking groove 16 at a position shifted by one on the foot side of the fixing member 17 while being spring-biased.

  In this example, the locking surface 46 is formed on the inner surface of the locking groove 16 opposite to the inclined surface 47, and the sliding direction A away from the seat 2 side with respect to the ottoman 6. When the load is applied to the stopper 29, the stopper 29 is not automatically unlocked, and the stopper 29 is unlocked only when the load is applied in the sliding direction B approaching the seat 2. Although it is provided in a structure like a so-called ratchet mechanism, a locking piece is also provided on the side of the inner surface of the locking groove 16 facing the inclined surface 47 as well as the inclined surface 47 (that is, the closer to the side opening 16a side). By forming an inclined surface (inclined so as to increase the distance to 42), the stopper 29 is automatically pushed out of the locking groove 16 even when a load is applied in the sliding direction A away from the seat 2 side. You may provide as follows.

  Thus, in the chair type massage machine of the present example having the above-described configuration, the user who is seated on the seat portion 2 of the massage machine main body 1 holds the left and right leg portions of his / her left and right leg portions of the pair of left and right ottomans 6 The groove portions of the calf holding portion 7 formed on the base end side of the ottoman 6 are fitted into the concave grooves 9, and the sole portions are applied to the groove portions of the sole holding portion 8 formed on the distal end side of the ottoman 6. In the state where the calf portion is fitted, the treatment means disposed on the inner wall of the groove portion of the sole holding portion 8 is driven to massage the sole portion, the toe, and the ankle portion, and the calf holding portion 7 The massage means can be massaged by driving the treatment means arranged on the inner wall of the groove portion.

  When the posture of the ottoman 6 is to be changed, the connecting support portion 19 may be rotated in the vertical direction around the support shaft 35 in front of the seat portion 2 of the massage machine body 1. The ottoman 6 can be moved to any posture between a vertical posture and a horizontal posture by rotating the ottoman 6 via the connection support portion 19.

  When the slide position of the ottoman 6 fixed to the connection support portion 19 by the slide fixing mechanism 30 is to be changed, it is inserted into one of the locking grooves 16 of the fixing member 17 as shown in FIG. The locking piece 42 of the stopper 29 is pulled using the adjusting lever 45 and the wire 44 and rotated in the direction B in the drawing, so that the engagement state between the locking piece 42 and the locking groove 16 is released. And after changing the sliding amount of the ottoman 6 with respect to the connection support part 19 via the slide mechanism 27, the adjustment lever 45 is returned and the stopper 29 is rotated by the urging | biasing force of the urging | biasing spring 41 in the a direction in the figure. If the engaging groove 16 is inserted into the engaging groove 16 different from the previously inserted engaging groove 16, the ottoman 6 is fixed to the connection support portion 19 again at the changed slide amount.

  The slide amount is changed as follows. For example, when the user is trying to increase the sliding amount of the ottoman 6 toward the distal end side because of the long body shape below the knee, the user releases the locking by the stopper 29 as described above. Thus, the ottoman 6 may be slid toward the distal end against the tensile force of the tension spring 33 by pushing the sole holding portion 8 toward the distal end with the sole portion. On the other hand, for example, when the user is trying to reduce the sliding amount toward the distal end side of the ottoman 6 because the user has a short body shape below the knee, the user rotates the stopper 29 to release the lock. Then, the ottoman 6 automatically slides toward the side close to the seat portion 2 by the tensile force of the tension spring 33.

  Then, the above-described unlocking of the stopper 29 is performed smoothly because the stopper 29 is a rotary type and the side opening 16a has a wide opening / removal operation. The slide adjustment can be performed smoothly even in the state of applying.

  Here, for example, when the ottoman 6 is largely slid to the front end side and the ottoman 6 is fixed by the slide fixing mechanism 30 and the ottoman 6 is rotated downward via the connection support portion 19 in this state, FIG. As shown in the figure, the tip of the ottoman 6 may be in contact with the floor surface. At this time, if the user puts his / her weight W on the tip of the sole holding part 8 of the ottoman 6, a force to lift the entire massage machine main body 1 around the grounding point P acts. It is dangerous and problematic for the massage machine body 1 to be lifted carelessly in this way, but a large load acts on the ottoman 6 toward the sliding direction B approaching the seat 2 side when lifted. In the chair type massage machine of the present example, the locking piece 42 of the stopper 29 is pushed out from the locking groove 16 as described above by this load, and after the locking is released, the fixing member 17 contracts by one step. It will be inserted into the locking groove 16 at the location. That is, since the sliding amount of the ottoman 6 is automatically changed so as to approach the seat 2, the lifting of the massage machine body 1 is prevented.
