Description

  The present invention relates to a chair type massage machine having a leg placement unit and a rotation position detector of the leg placement unit.

2. Description of the Related Art Conventionally, in a chair with a massage function having a leg placement portion, a chair that can move the leg placement portion is known in order to achieve compactness or space saving when not in use.
In JP-A-9-266933, as shown in FIG. 20, a seat body 121 having a massage body (bag body) 120 driven by a driving means 120 and a backrest portion 122, and the seat body 123, And a leg mounting base 125 connected to the part 121 by a connecting member 124, and when the leg mounting base 125 is used, it is disposed in front of the seat part 121 with one side face facing upward, and when not in use, the one side face side Describes a chair-type massage machine that is placed on the seat with the seat facing the seat 121. This chair type massage machine is provided with detecting means 126 for detecting that one side surface of the leg mounting table 125 is opposed to the seating surface of the seat 121 on either the chair body 123 or the leg mounting table 125. Based on the detection by the detecting means 126, the driving means is in a non-driving state.
As shown in FIGS. 21 to 22, the detection means 126 is a micro switch 129 provided with a weight 128 movably provided in the housing 127 and a contact point that contacts or separates by pressing or releasing the pressing by the weight 128. When the one side surface of the leg mounting table 125 is opposed to the seat surface of the seat portion 121, the contact point is not in contact with each other, whereby the driving means is brought into a non-driven state. Thus, in the chair type massage machine described in Japanese Patent Laid-Open No. 9-266933, the massage body does not operate in a state in which the leg placement table is placed on the seat, and thus the erroneous use of the chair type massage machine can be prevented. The effect that can be obtained.

  Further, as shown in FIG. 23, Japanese Patent Laid-Open No. 2001-299849 discloses a seat portion 100 that can be placed directly on a placement surface such as a floor or a tatami mat, and a reclining mechanism at the rear end of the seat portion 100. And a seat chair type massage machine including a backrest portion 101 that accommodates a massage mechanism portion is disclosed, and an upper seat / leg rest portion 102 is provided at a front end portion of the seat portion 100. The upper seat / leg rest portion 102 is configured to overlap the seat portion 101 when reversed to the backrest portion 101 side.

  Furthermore, Japanese Patent Laid-Open No. 7-39571 discloses a chair type massage machine that can receive a massage in a seated state as shown in FIGS. 24 to 25. The main body is composed of a seat portion 110 for sitting, a backrest 111 attached to one end portion of the seat portion 110 so that it can be tilted up and down, and an ottoman 112 attached to the other end portion of the seat portion so that it can be pulled out. In addition, there are described a manual type in which the raising and lowering of the backrest 111 and an operation of putting in and out the ottoman 112 connected to the link mechanism 114 attached to the frame 113 are manually performed, and an electric type in which the backrest 111 is electrically operated. .

However, the detection means 126 in the massage machine described in Japanese Patent Application Laid-Open No. 9-266933 is configured to press the retractable protrusion 129a provided on the microswitch 129 via the action piece 129b when the weight 128 moves. Therefore, the minute rotation of the leg mounting table 125 cannot be detected. That is, even when an excessive load is applied to the leg mounting table 125 from above when the leg mounting table 125 is in a predetermined posture state (normal state) at the front position of the seat 121, Japanese Patent Application Laid-Open No. 9-266933. In the detection means 126 in the massage machine described in the publication, the microswitch 129 cannot be turned off because the contact remains closed until the leg mounting table 125 is slightly rotated. Therefore, the massaging operation cannot be stopped in spite of an abnormal state in which the leg mounting table 125 receives an excessive load.
Further, in the massage machine described in Japanese Patent Laid-Open No. 2001-299849, the leg rest can only be grounded to the floor, and the leg rest cannot be held in a state separated from the floor. For this reason, the seating surface has to be lowered, and it is difficult to sit down, and the entire bottom surface of the leg rest is in contact with the floor, so even if the leg rest has a massage function, the massage effect on the legs is insufficient It is. Furthermore, the massage machine described in Japanese Patent Laid-Open No. 7-39571 can support the ottoman from below with a link mechanism or the like and hold the ottoman away from the floor surface. If an excessive load is applied from above such as sitting on the top, the link mechanism holding the ottoman may be damaged.

The present invention has been made in order to solve such a problem of the prior art, and can reliably detect a slight rotation of the leg placement portion (base) from a predetermined posture position. The first object of the present invention is to provide a chair type massage machine capable of reliably stopping the operation of the massage function and a rotation position detector for the leg rest when the part is located outside the predetermined normal position. .
Moreover, even when an unexpected excessive load is applied to the leg rest (ottoman) held in a state of being separated from the floor surface, the mechanism portion holding the leg rest can be prevented from being damaged. The second object is to provide a chair type massage machine that can be used.

And a fixed body 45 provided on the side end). The movable body 43, the coil spring 44, and the fixed body 45 are provided in a casing 46 fixed to the leg placement unit 10, and only the fixed body 45 is fixed to the casing 46. . Further, a guide shaft 47 protruding from the side surface of the moving body 43 is inserted into a guide groove 48 formed in the casing 46 so that the moving body 43 can move smoothly.

  The shape of the moving body 43 is not particularly limited in the present invention, but in the present embodiment, it has a substantially box shape, and can be in surface contact with the side surface 40a of the support arm 40 at its tip. An engagement surface 43a and a rotation surface 43b following the engagement surface 43a are formed. The rotating surface 43b is formed of a curved surface that is convex on the side of the support arm 40 in a state where the leg placement unit 10 is held in a predetermined posture. In addition, at the boundary between the engagement surface 43a and the rotation surface 43b, the leg placement unit 10 may be in line contact with the side surface of the support arm 40 when the leg placement unit 10 rotates under a load larger than a predetermined load. A rotation edge 43c is formed.

  The engagement surface 43a abuts on the side surface 40a of the support arm 40 and plays a role of defining a predetermined posture of the leg placement portion 10 at the front position of the seat base portion 1 (see FIG. 4). In this state, when a load exceeding a predetermined load is applied to the leg placement unit 10 due to an accidental person sitting on the leg placement unit 10, the moving body 43 is applied to the side surface 40 a of the support arm 40. When pressed, the coil spring 44 is compressed by the moving body 43. At that time, first, an upper end (upper end in FIGS. 4 to 5) 43d of the engagement surface 43a is separated from the side surface 40a of the support arm 40, and then the moving body 43 starts from the rotation edge 43c. The coil spring 44 is compressed by being pressed by the side surface 40a of the support arm 40 while being in line contact with the side surface 40a of the support arm 40. As described above, in the present invention, the leg mounting portion 10 is made rotatable so that the support arm 40 and the like are not damaged by an excessive load acting on the leg mounting portion 10. And when the said load is lost, the leg mounting part 10 will return to an initial state naturally with the elasticity of the coil spring 44. FIG. In the present embodiment, by appropriately selecting the elasticity and length of the coil spring 44 and the shape of the moving body 43, specifically, the inclination angle of the engaging surface 43a that makes surface contact with the side surface of the support arm 40, The leg placing part 10 can be held at a desired angle. Also, the load for starting the rotation (the predetermined load in the claims) can be adjusted by appropriately selecting the elasticity and length of the coil spring 44, and damage to the support arm 40 and the like can be prevented. It can be surely prevented.

  In the present embodiment, a curved surface that is convex on the support arm 40 side is adopted as the rotation surface 43b, and the leg placement unit 10 can be smoothly rotated. In the invention, the shape is not particularly limited. For example, the surface may be a surface having a plurality of flat surfaces with a small width and a curved surface as a whole. Furthermore, when the installation position of the chair type massage machine C is fixed or the like, the degree to which the leg placement unit 10 is rotated to the maximum is constant (the tip of the rotated leg placement unit 10 is the chair type massage machine C). In the case where the rotation of the leg placement unit 10 is stopped by hitting the floor surface of the installation place, a plane following the engagement surface 43a may be adopted as the rotation surface 43b. In this case, the inclination angle of the flat surface with respect to the engagement surface 43 a can be set so that the flat surface comes into contact with the side surface of the support arm 40 at the same time that the tip of the leg placement portion 10 hits the floor surface. In addition, when a flat surface is adopted as the rotation surface 43b, the chair-type massage machine C is placed in a state in which the rotation of the leg placement unit 10 is allowed even after the flat surface comes into contact with the side surface of the support arm 40. Care must be taken because the support arm 40 and the like may be damaged when a load is applied to the leg placement unit 10.

  Moreover, in this Embodiment, as shown in FIGS. 6-7, although two coil springs are used with respect to one attitude | position control mechanism 30, the number of coil springs may be one, There may be three or more, and when the leg resting portion 10 is held in a predetermined posture at the front position of the seat base portion 1 and the load acting on the leg resting portion 10 is removed, the leg resting portion 10 is removed. The number and the length are not particularly limited in the present invention as long as the elasticity that can return the mounting portion 10 to the predetermined posture is obtained. As the biasing means, an actuator such as an air cylinder or a hydraulic cylinder can be used instead of the coil spring.

  In the embodiment according to the chair type massage machine of the first invention in the present invention and the rotation position detector of the leg mounting portion of the second invention, the rotation position detector for detecting the rotation position of the leg mounting portion 10. (Hereinafter, also simply referred to as a detector), the rotation position of the leg placement unit 10 is detected by this detector, and when the leg placement unit 10 is not at the predetermined rotation position, the massage of the chair type massage machine C is performed. The function is stopped. 8 to 10 show an example of such a detector, and in the present embodiment, the detector 60 is near the rear end of the leg placement portion 10 (near the connection portion with the seat base portion 1). Reference). The detector 60 can be rotated by its own weight around a Hall IC 63 that is a magnetic sensor mounted on a substrate 62 disposed in the case 61 and a shaft 64 that protrudes from the case 61. And a magnet portion 65 which is a rotating body attached to the shaft 64.

  The case 61 is made of, for example, a synthetic resin such as ABS, nylon, polypropylene, or polyethylene, and the shaft 64 projects from an inner wall surface thereof. The magnet portion 65 has a substantially box shape as a whole, and is made of a synthetic resin such as ABS, nylon, polypropylene, polyethylene or the like, similar to the case 61. A magnet 66 made of a ferrite magnet, a rare earth magnet, or the like is embedded in the magnet portion 65, and the magnetic flux density applied to the Hall element in the Hall IC 63 by the magnet 66 varies depending on the position of the magnet 66. Using this, it is detected whether or not the leg placement unit 10 is in a predetermined rotation position, that is, whether or not the Hall IC 63 and the magnet 66 are in a predetermined positional relationship. The case 61 and the magnet portion 65 can be made of a metal such as aluminum.

  FIG. 8 shows the detector 60 in a state in which the leg placement unit 10 is folded on the seat base unit 1, and since the magnet 66 and the Hall IC 63 are in a positional relationship apart from each other, the switch is in an off state. Become. At this time, the massage function of the chair type massage machine C cannot be operated. On the other hand, when the leg placement portion 10 is rotated around the rotation fulcrum and positioned at the front position of the seat base portion 1, the case 61 provided with the Hall IC 63 is rotated by approximately 180 °. (The magnet portion 65 rotates about the shaft 64 so that the side opposite to the shaft-supported side always faces downward (vertically downward) by its own weight. See FIG. 9). At this time, since the magnet 66 and the Hall IC 63 are opposed to each other and are in the closest positional relationship, the switch is turned on. In this state, the massage function of the chair type massage machine C can be activated by operating the remote controller body 50.

  Further, in the state where the massage operation shown in FIG. 9 is possible, if a load exceeding a predetermined load such as a person sitting on the leg placement unit 10 by mistake acts on the leg placement unit 10, the leg placement unit 10. Rotating around the pivot fulcrum prevents damage to the support arm 40, but the case 61 in which the Hall IC 63 is disposed also rotates with this rotation, as shown in FIG. In addition, since the Hall IC 63 is separated from the magnet 66, the magnetic flux density of the Hall element changes and the switch is turned off. Therefore, even if the massage function is activated at this time, the switch is turned off by the detector 60, so that the massage function is immediately stopped. The position of the detector 60 is not particularly limited in the present invention as long as the detector 60 is provided on the leg placement unit 10, and the detector 60 is not limited to the vicinity of the connecting portion with the seat base unit 1. It can be fixed at a desired position such as near the tip, in the center, or on both sides. Moreover, not only one but two or more can be provided.

  Furthermore, in the present embodiment, a magnetic sensor is employed as the detector, but other detectors such as a limit switch, an optical sensor, and an angle sensor can also be used. For example, when using an optical sensor, as shown in FIG. 11, a light emitting element 68 is provided at a location where the Hall IC 63 is disposed in FIG. 8, and a light receiving element (on the inner surface of the case 61 facing the light emitting element 68 ( (Not shown) may be provided. In this case, when the leg placement part 10 is overlapped on the seat base part 1 (FIG. 11), the switch is turned off, and when the leg placement part 10 comes to a predetermined position in front of the seat base part 1 (FIG. 12), It can be set so that the shield (rotating body) 67 that can rotate under its own weight is switched on as a result of blocking light. In the case of an angle sensor, the massage function can be controlled to be turned on / off by being installed on the rotation shaft of the leg placement unit 10 and detecting the rotation angle of the leg placement unit 10.

  The rotating portion 56 is supported by the lower base 54 by fitting a shaft portion 56 a projecting from one end thereof into a hole formed in the lower base 54. In addition, three ribs 56b are formed at equal intervals along the axial direction on the peripheral wall of the rotating portion 56, and a slope 56c is formed at the tip of the rib 56b. The guide portion 57 has a substantially short cylindrical shape as a whole, and is composed of three pieces of guide bodies 57a arranged at equal intervals in the circumferential direction. A passage having a width through which the rib 56b can pass is formed between the adjacent guide bodies 57a, and the lower end of each guide body 57a is formed in a saw blade shape.

An operating shaft 58 that pushes down the rotating portion 56 protrudes from the bottom surface of the upper base 53, and a protruding portion 58 a at the tip of the operating shaft 58 is slidable in a recess formed on the upper surface of the rotating portion 56. Has been inserted. In addition, six mountain-shaped protrusions 58 b are formed at regular intervals on the tip of the operation shaft 58.

FIG. 17 is an explanatory view of the vicinity of the lower portion of the casing when the remote control main body 50 is pushed up, and the lower base 54 is urged upward by the coil spring 55. At this time, the rib 56b of the rotating portion 56 is located in the passage between the guide bodies 57a. In this state, as shown in FIG. 13, the end of the remote control main body 50 slightly protrudes from the opening of the casing 51, so that the user can grab this end and take out the remote control main body 50 from the casing 51. it can.
On the other hand, when the remote controller main body 50 is accommodated in the casing 51 after use, when the remote controller main body 50 is inserted into the casing 51 and the end of the remote controller main body 50 is pushed in, the slope of the mountain-shaped protrusion 58b of the operation shaft 58 is The rotating portion 56 is pushed downward by coming into contact with the inclined surface of the tip of the rib 56b. When the tip of the rib 56b reaches the lower end of the passage, the rotating portion 56 is rotated clockwise (clockwise as viewed from the opening side of the casing) by the inclined surface of the tip of the rib 56b being guided by the inclined surface of the mountain-shaped protrusion 58b. ). Then, the rib 56b is guided by the inclined surface of the saw blade portion of the guide body 57a and locked to the retracted portion of the saw blade portion, so that the upper base 53 is disposed at the lower position. In this state, since the remote controller main body 50 is almost housed in the casing 51, the armrest portion 6 has no protrusions and has a very clean appearance.

  In the chair type massage machine C according to the third aspect of the present invention, as described above, an excessive load acting on the leg placement unit 10 is applied to the support arm and the like when the leg placement unit 10 rotates. However, for safety, it is preferable to stop the massage function when the leg placement unit 10 is rotated. For this purpose, detection means such as a limit switch, an optical sensor, or a magnetic sensor for detecting the rotation of the leg mounting unit 10 can be provided in the vicinity of the rotation fulcrum of the leg mounting unit 10. And it is preferable to comprise so that the control part (not shown) of the chair C may stop the drive of a massage part in response to the signal from this detection means.

  In the above-described embodiment, the case has been described in which the leg placement unit 10 folded on the seat base unit 1 is disposed in front of the seat base unit 1 by rotation. The present invention can be applied to the case where the leg placement portion 10 is disposed below the front end of the seat base portion 1 when the leg placement portion 10 is not used. . FIG. 19 shows a partially broken side view of the vicinity of the front end of the seat base in such a case. In FIG. 19, the configuration shown by the same reference numerals as in FIG. 3 is the same as that in FIG. The leg placement part 10 is arranged in a state of being folded below the front end of the seat base part 1 when not in use. Then, using an air cell, an air cylinder, or the like (not shown), the leg placement unit 10 is rotated to a position in front of the seat base unit 1 and separated from the floor surface. At this time, the engaging surface 43a of the moving body 43 abuts on the side surface 40b at the tip of the support arm 40, and the leg placement unit 10 is held in a predetermined posture. Even if a load larger than a predetermined load acts upward on the leg placement unit 10 such as trying to move the chair type massage machine C with the leg placement unit 10 in this posture, the leg placement unit 10 does not Since it can also rotate upwards, the connection part of the said leg mounting part 10 and the seat base part 1 is not damaged.

As shown in FIG. 15, the chair type massage machine C includes a control unit for driving motors, heaters, electromagnetic valves, and pumps built in the chair type massage machine C. Controls the driving of the motors and the like based on input signals from the remote controller main body 50 and signals from various sensors, limit switches, and rotation position detectors.

  First, when the main power supply is turned on, the microcomputer including the control unit is initialized (step S1). Next, after various settings (for example, settings such as mode setting by a jumper, frequency setting, etc.) are performed (step S2), chattering is removed in consideration of the leg placement portion being shaken by a spring (step S3). ). The chattering is removed by reading the rotational position detector at predetermined time intervals (for example, 5 msec), and when the same value is read a predetermined number of times, for example, three times continuously, the value is read by the rotational position detector. The initial state value is determined (step S4).

  Next, when a predetermined time (for example, 5 msec) elapses after the determination of the initial state value of the rotational position detector, the rotational position detector is read again in order to improve the reliability, and the chair type is based on the value. The current shape of the massage machine C is determined (steps S5 to S6). That is, whether the leg placement part is in a predetermined position in front of the seat base part (is a state where it can be used as a massage machine, for example, the switch is on (High) as shown in FIG. 9), Alternatively, it is determined whether the leg placement portion is folded on the seat base portion (a state where it can be used as a sofa or a chair, for example, the switch is off as shown in FIG. 8). .

  And if it is judged that it is a sofa shape, in the remote control main body 50, only commands such as power off (return) (command for returning from emergency stop), emergency stop, heater ON / OFF, and reclining UP / DOWN are possible. Shoulder position adjustment, foot reclining UP / DOWN, air flip strength (how to raise the plate when the plate is raised by air cell) and automatic / manual massage The command of setting becomes impossible. On the other hand, if the shape is determined to be a massage machine shape, not only operations that can be performed in the sofa shape, but also commands that are impossible in the sofa shape, such as the shoulder position adjustment, are possible.
