JP-A-11-299570

However, when both the vertical rotation and expansion / contraction of the leg placement part are to be realized, there arises a problem that the leg placement part hits the floor.
For example, if the leg placement part is extended in a state where the leg placement part is turned downward and turned downward, the tip of the leg placement part may hit the floor.
Further, when the leg placement unit is rotated downward with the leg placement unit extended, the leg placement unit may hit the floor.

Despite such problems, conventionally, it has not been possible to detect whether or not the leg placement unit has hit the floor.
It is an object of the reference invention to detect whether or not the leg placement unit is in contact with the floor surface.
An object of this invention is to prevent that a leg mounting part contacts a floor surface.

The present invention provides a chair body having a seat part, a leg placing part that is provided on the front side of the seat part and capable of vertically rotating and extending and retracting, and at least the chair body and the leg placing part. In a massage machine provided with any one of the massage units, an angle detection sensor that detects an angle of the leg placement unit, and a control unit that controls the operation of the leg placement unit, The control unit controls an extension operation of the leg placement unit based on a detection result of the angle detection sensor .
In addition, when the angle detection sensor detects that the angle of the leg placement unit is downward, the control unit preferably performs control for restricting the extension of the leg placement unit.

Moreover, it is preferable that the said control part performs control which contracts the said leg mounting part during the downward rotation of the said leg mounting part.
In addition, the apparatus further includes an up / down rotation drive device that rotates the leg placement unit up and down, and an expansion / contraction drive device that drives the leg placement unit to extend and contract, and the control unit includes the up / down rotation drive device and the It is preferable that the leg mounting portion is contracted while the leg mounting portion is rotated downward by controlling the telescopic driving device.
Further, the control unit controls so that the lowering operation and the contracting operation of the leg mounting unit are performed at the same time, so that the tip of the leg mounting unit is along the floor surface. It is preferable to descend while shrinking.

The reference invention includes a chair body having a seat part, a leg placing part that is provided on the front side of the seat part and capable of vertically rotating and extending and retracting, and at least the chair body and the leg placing part. The massage machine provided with the massage part provided in either one WHEREIN: The said leg mounting part is provided with the floor detection sensor which detects whether it is in contact with the floor surface.
According to the reference invention, the floor detection sensor can detect whether or not the leg placement unit is in contact with the floor.
In the massage machine, the leg placement unit is expanded during the upward rotation of the leg placement unit, or the leg placement unit is contracted during the downward rotation of the leg placement unit. Are preferred. In this case, since the vertical rotation and expansion / contraction are performed simultaneously, the operation becomes efficient. In addition, even if the vertical rotation and expansion / contraction are performed simultaneously, the floor detection sensor can detect whether or not the leg placement unit is in contact with the floor surface. it can.
Moreover, it is preferable that the said massaging machine stops the expansion | extension of the said leg mounting part, if it detects that the said floor detection sensor is contacting the floor surface during the expansion | extension of the said leg mounting part. In this case, since the extension automatically stops when the leg placement unit hits the floor during extension, the leg placement unit can be prevented from being damaged.

  Further, when the massage machine detects that the floor detection sensor is in contact with the floor surface during the downward rotation of the leg placement portion, the leg placement portion rotates downward while contracting. Preferably there is. In this case, even if the leg placement portion hits the floor during the downward rotation, the leg placement portion contracts so as to allow further downward rotation, so that a smooth downward rotation can be realized.

  In addition, when the massage machine detects that the floor detection sensor is in contact with the floor surface during extension while the leg placement unit is rotating upward, the leg support unit suppresses extension of the leg placement unit. It is preferable that the mounting portion is pivoted upward. In this case, when the leg placement portion hits the floor during the upward rotation and extension, the extension of the leg placement portion is suppressed, so that a smooth upward rotation can be realized.

  Also, a chair body having a seat part, a leg placement part which is provided on the front side of the seat part and can perform an expansion / contraction operation, and a massage provided on at least one of the chair body and the leg placement part In the massage machine, the leg placement portion includes a sole contact portion with which the sole of the user abuts, and the sole contact portion is in contact with the sole. A foot detection sensor for detecting whether the foot contact portion is in contact with the sole during the contraction operation of the leg placement portion. It is preferable that the position of the sole contact portion is adjusted by stopping the contraction of the portion. In this case, since the leg placement portion contracts until the sole contact portion comes into contact with the sole, the position adjustment of the sole contact portion can be easily and appropriately adjusted.

  In addition, it is preferable that the position adjustment is performed by automatically contracting the leg placement part after the leg placement part is rotated upward or downward. Even for the same user, the position of the appropriate foot contact portion changes depending on the vertical position of the leg placement portion. The position adjustment should be performed by automatically contracting the leg placement unit after the leg placement unit has been rotated upward or downward. Each time the mounting portion is rotated up and down, the sole contact portion is automatically adjusted to an appropriate position.

  In addition, when the position adjustment is performed (for example, after the leg placement portion is turned upward or downward), when the sole is already in contact with the sole contact portion, It is preferable to perform the position adjustment by contracting the leg placement portion after the leg placement portion is once extended and the sole contact portion is separated from the sole. In this case, when the position adjustment is performed, even if the sole is already in contact with the sole contact portion, the leg placement portion is temporarily extended, so that the position adjustment can be reliably performed. Further, when the leg placement portion is once extended, it is preferable to stop the extension when detecting that the floor surface detection sensor is in contact with the floor surface during the extension. This can prevent the floor from damaging the floor.

  Moreover, it is preferable that the leg placement unit includes a wheel for rolling contact with the floor surface. In this case, the contact between the leg placement unit and the floor surface becomes smooth.

The air cell 13 is arrange | positioned so that a press massage may be performed to a user's buttocks and thigh.

The leg placement unit main body 50 includes a plurality of (two in the illustrated example) leg holding members 51 on which the legs of the user (here, “legs” include “legs” ahead of the ankles). 52 are arranged in the length direction of the leg. In the following, the leg holding member closer to the seat part 3 is referred to as a first leg holding member 51, and the leg holding member farther from the seat part 3 is referred to as a second leg holding member 52.
The first leg holding member 51 is placed on the vicinity of the calf of the user's leg. And. That is, the first leg holding member 51 is formed in a U-shaped cross section so that both legs can be inserted between the left and right side surfaces 51b and 51b.

  The second leg holding member 52 is for placing the foot of the user, and includes a bottom surface portion 52a on which the heel (and ankle) and the side surface portion 52b are erected from both left and right sides of the bottom surface portion 52a. 52b and a sole contact portion 52c erected from the distal end side of the bottom surface portion 52a. In addition, the left and right central position 52a-1 of the bottom surface portion 52a is a protruding portion that is divided into left and right sides, and the left and right feet of the user are placed on the left and right sides of the protruding portion 52a-1. Thus, the sole of the user can come into contact with the sole contact portion 52c with the foot placed.

  In addition, the sole contact portion 52c is provided with a sole detection sensor 53 that detects whether or not the foot of the user is in contact with the sole contact portion 52c. The sole detection sensor 53 is configured as a planar switch. The switch is turned on when the sole hits the sole contact portion 53, and the switch is turned off when the sole is separated.

  The sole detection sensor 53 is arranged so as to detect whether or not the heel vicinity of the sole (the rear side of the sole) is in contact with the sole contact portion 52c. In other words, the sole detection sensor 53 is disposed at a position near the bottom surface portion 52a of the sole contact portion 52c, and more reliably than when disposed at a position for detecting the toe side of the sole. It is possible to detect whether or not the soles are in contact.

  The leg placement part 5 is provided with a massage part 14, and the massage part 14 of the leg placement part 5 expands and contracts by supply and discharge of air, and an air cell for massage that applies pressure massage to the user. It is constituted by. The air cell 14 is disposed on the bottom surface portion 51a and the side surface portion 51b of the first foot holding member 51 and the bottom surface portion 52a, the side surface portion 52b, and the sole contact portion 52c of the second holding member. Can be massaged. In addition, the massage part 14 of the sole contact part 52c is disposed closer to the toe side than the sole detection sensor 53, and massage is performed on the toe side, which is the terminal side of the body, to increase blood flow promotion. A massage effect is obtained. In addition, an overlap between the massage part 14 and the sole detection sensor 53 is avoided, and a suitable arrangement of the massage part 14 and the sole detection sensor 53 in the sole contact part 52c is realized.

  The support device 6 that supports the leg placement unit main body 50 is configured to be extendable in the length direction of the legs of the user. That is, the support device 6 includes a device base 61 attached to the front end of the seat portion 3 so as to be rotatable up and down, and a slide member 62 attached to the device base 61 so as to be slidable in the length direction of the user. 63, and by sliding the slide members 62, 63 with respect to the device base 61, the support device 6 can be expanded and contracted to change its length. That is, the support device 6 can be extended from the contracted state as shown in FIG. 1 as shown in FIG.

  In the present embodiment, two (plural) slide members 62 and 63 are provided, and the first slide member 62 slidably attached to the apparatus base 61 and slidable with respect to the first slide member 62. And a second slide member 63 attached to the. The slide members 62 and 63 are configured to slide in association with each other with respect to the apparatus base 61 by a link mechanism or the like (not shown) and to be positioned at an arbitrary position. The slide members 62 and 63 are driven to extend and contract by an expansion / contraction drive device (not shown in FIGS. 1 and 2) such as an electric motor and a screw feed mechanism provided on the apparatus base 61.

  The first leg holding member 51 is supported by the first slide member 62 so as to slide together with the first slide member 62. The second leg holding member 52 is supported by the second slide member 63 so as to slide together with the second slide member 63. Accordingly, the slide members 62 and 63 move from the contracted state as shown in FIG. 1 in the length direction of the legs of the user by the telescopic drive device, move away from the seat portion 3 as shown in FIG. The mounting portion 5 can be in an extended state.

  The leg placing portion 5 includes wheels 54 and 54 on both left and right sides of the tip portion. The wheel 54 is provided at the distal end portion of the second slide member 63 (support device 6) so as to roll and come into contact with the floor surface when the leg placement portion 5 is inclined downward or downward. The wheels 54 are arranged on both the left and right sides of the second slide member 63. Even if the tip of the leg mounting part 5 hits the floor surface when the leg mounting part 5 is inclined downward or downward, it can be prevented that the wheel 54 actually touches the floor surface and the floor surface is damaged, The front end portion of the leg placing portion 5 can move smoothly along the floor surface.

  Also, as shown in FIG. 4, a floor detection sensor 55 for detecting whether or not it is in contact with the floor surface F is provided at the distal end portion of the second slide member 63 of the leg placement portion 5. . This floor detection sensor 55 is urged by a urging member (spring) 55a so as to protrude forward from the wheel 54 when the tip of the leg placement portion 5 is not in contact with the floor surface F. And a limit switch 55c that is turned off when the detection body 55b is in contact with the floor surface F and moves backward when the detection body 55b is not in contact with the floor surface F. I have.

  Therefore, when the leg placing part 5 is downward and the tip part is in contact with the floor surface F as shown in FIG. 4A, or when the leg placing part 5 is inclined forward and downward as shown in FIG. 4B. Even if it is extended to the extent that it is in contact with the floor surface F, the floor detection sensor 55 is turned ON, and the tip of the leg rest portion 5 is in contact with the floor surface F as shown in FIG. If not, the floor detection sensor 55 is turned off.

  FIG. 5 shows a control block in the massage machine 1. The massage machine 1 includes a reclining drive device 71 for the backrest portion 3, a vertical rotation drive device 18 for the leg placement portion 5, and a telescopic drive for the leg placement portion 5. A control unit 73 that controls the device 72 is provided. The control unit 73 also performs control for automatic position adjustment (described later) of the leg placement unit 5. For these controls, the control unit 73 is also given detection results of the sole detection sensor 53 and the floor detection sensor 55. An operating device 74 for operating each driving device 18, 71, 72 is also connected to the control unit 73. The operation device 74 includes a “foot slide extend” button 74 a for performing an extension operation of the leg placement unit (footrest) 5, a “foot slide contraction” button 74 b for performing a contraction operation of the leg placement unit 5, legs A “footrest raising” button 74c for performing an upward rotation operation of the mounting portion 5, a “footrest lowering” button 74d for performing a downward rotation operation of the leg mounting portion 5, and a raising operation of the backrest portion 2. "Reclining" button 74e, and "Reclining" button 74f for performing a tilting operation of the backrest 2 are provided. Although not shown, the operation device 74 is also provided with buttons for operating the massage units 10, 13, and 14.

  FIG. 6 shows an operation flowchart when the leg placement unit 5 is extended. When the “foot slide extension” button 74a of the operation device 74 is operated and turned on (step S11), the leg placement unit 5 is extended unless the floor detection sensor 55 is turned on (step S12) (step S13). ). The leg placement unit 5 is extended until the extension limit (position in FIG. 2) is not reached (step S14) until the button 74a is turned off (step S15). Even if the button 74a is not turned OFF, when the leg placement unit 5 reaches the extension limit (step S14), the extension operation stops (step S16). Here, the state where the button 74a is pressed is ON, the state where the finger is released from the button 74a is OFF, and the same applies to the other buttons.

  The massage machine 1 is provided with an angle detection sensor (not shown) for detecting the angle of the leg placement unit 5, and the extension operation of the leg placement unit 5 is controlled based on the detection result of the angle detection sensor. May be. Specifically, even if the floor detection sensor 55 is not turned on, if the angle of the leg placement unit 5 is substantially downward, the leg placement unit 5 hits the floor without being extended. May be prevented in advance.

  When the leg detection unit 55 is turned on while the tip of the leg placement unit 5 is in contact with the floor during the extension operation of the leg placement unit 5 (step S12), the extension operation is interrupted (step S15). If the button 74a is turned off while the extension operation is interrupted, the extension operation is completed, or if the floor detection sensor 55 is turned off by rotating the leg rest 5 during the extension operation, the extension operation is resumed. Performed (step S15).

  FIG. 7 shows an operation flowchart when the leg placement unit 5 is contracted (shortened). When the “foot slide contraction” button 74b of the operation device 74 is operated and turned on (step S21), the leg placing unit 5 contracts and becomes shorter. (Step S22). The contraction operation is continued while the button 74b is turned on unless the contraction limit of the leg rest 5 is reached (step S23), and the contraction operation is stopped when the button 74b is turned off (step S24). Also, when the contraction limit is reached during the contraction operation (step S23), the contraction operation stops (step S25).

  8 and 9 show a flowchart in the case of causing the leg placement unit 5 to rotate upward (upward). When the “lift footrest” button 74c of the operation device 74 is operated to turn it on (step S301), the leg placing unit 5 is raised (step S302) and the leg placing unit 5 is extended (step S306). If the leg placement part 5 does not extend when the leg placement part 5 is raised, the sole contact part 52c presses the sole of the user, but in this embodiment, the leg back placement part 5 Is lifted while extending, and the sole contact portion 52 moves away from the sole, so that the sole contact portion 52 is prevented from pushing the sole during the rise.

  In principle, the leg placement unit 5 is raised and extended until the button 74c is turned off (step S309). However, when the upper limit of the leg rest 5 is reached during the ascending (step S303), the ascending operation is stopped (step S304). Further, when the floor detection sensor 55 is turned ON during extension, the extension operation is interrupted (extension operation is skipped) until the leg placement unit 5 is raised and the floor detection sensor 55 is turned OFF, and extension is suppressed. (Step S305). In other words, during the initial rising period, the leg placing portion 5 rises while the wheel 54 at the tip thereof extends while rolling along the floor surface. If the leg placement unit 5 reaches the extension limit during extension (step S307), the extension operation stops (step S308).

  If the angle of the leg placement unit 5 is substantially downward (in the initial state of the ascending operation), the leg placement unit 5 immediately hits the floor surface without being extended. This may be prevented.

When the button 74c is turned off (step S309), the leg placement unit 5 stops the ascending operation at an arbitrary ascending position or ascending limit position (step S310). As shown in FIG. 9, the automatic position adjustment of the leg placement unit 5 is subsequently performed. For this automatic position adjustment, first, the foot contact portion 52c is treated on the condition that the leg placement portion 5 is not in contact with the floor surface (the floor detection sensor 55 is not ON) (step S311). A process of determining whether or not the person is away from the sole of the foot (step S312) is performed.
When the sole contact portion 52c is separated from the sole (when the sole detection sensor 53 is OFF) (the extension operation is stopped if the extension operation is performed, and then the contraction operation is performed) (step S313). ).

  When the leg placing portion 5 contracts and the sole contact portion 52c contacts the sole (the sole detection sensor 53 is turned on) (step S314), the contraction operation stops (step S316), and the sole The position of the contact portion 52c is adjusted to be in a state where the contact portion 52c is exactly fitted to the sole. The contraction operation is also stopped when the leg placing unit 5 reaches the contraction limit (step S315).

  In the determination process (step S312), when it is determined that the sole contact portion 52c is in contact with the sole (the sole detection sensor 53 is ON), the contraction operation is immediately performed for position adjustment. Instead, the foot contact portion 52c is once extended to release the sole (step S317), and then the contraction operation is performed (step S313). Therefore, when the position is adjusted, a state in which the sole contact portion 52 and the sole are separated can be obtained with certainty, and the contraction operation can be performed reliably. Since the position adjustment is always performed by a contraction operation, an operation suitable for position adjustment is obtained.

  Even when the expansion limit is reached during the expansion operation in step S317 (step S318), the contraction operation is started (step S313). In step S311, the contraction operation is also started when it is determined that the floor detection sensor 55 is ON (step S313).

The position at which the sole contact portion 52c fits the sole changes depending on the vertical position of the leg placing portion 5. However, as described above, after the vertical position of the leg placing portion 5 is determined, the sole is retracted by the contraction operation. By adjusting the position of the abutment portion 52 so as to match the sole of the foot, the position of the second leg holding member 52 is exactly aligned with the position of the foot of the user, and the second leg holding member 52 The massage unit 14 can reliably massage the feet. In particular, massage on the soles is appropriate.
In addition, in the present embodiment, the leg holding members 51 and 52 move in conjunction with each other (if the movement amount of the second leg holding member 52 is large, the movement amount of the first leg holding member 51 is large, and the second leg holding member 52 is moved). If the movement amount of the first leg holding member 51 is small, the movement amount of the first leg holding member 51 is also small). Therefore, the first leg holding member 51 that massages the calf's vicinity is also treated with the leg length or knee bending angle. Depending on the position of the calf, the position of the calf is adjusted so that it can be properly massaged.

  10 and 11 show a flowchart when the leg placement unit 5 is rotated downward (downward movement). When the “footrest lowering” button 74d of the operation device 74 is operated and turned on (step S401), the leg placing unit 5 is lowered (step S402).

  In principle, the lowering (and contraction) of the leg rest 5 is performed until the button 74d is turned off (step S411). When the lowering limit of the mounting portion 5 is reached during the lowering (step S403), the lowering operation is stopped (step S404).

  The leg placement unit 5 that is being lowered does not contract unless the leg placement unit 5 is in contact with the floor surface (steps S406 and S407), but the floor detection sensor 55 is turned on by lowering and contacting the floor surface. Then (step S407), a contraction operation is performed (step S408). That is, the lowering operation and the contracting operation are performed at the same time, and the tip (wheel 54) of the leg placing portion 5 is lowered while contracting along the floor surface. During the contraction operation (step S406), the contraction operation step S408 is continuously executed. When the contraction limit is reached (step S409), the contraction operation is stopped (step S410), and the button 74d is turned off. Until it becomes, it will be in a standby state in a contracted state (steps S405 and S411).

  When the button 74c is turned OFF (step S411), the leg placement unit 5 stops the lowering operation at an arbitrary lowering position or lowering limit position (step S412). Subsequently, automatic position adjustment of the leg placement unit 5 is performed. This automatic position adjustment is the same as the automatic position adjustment after ascending shown in FIG. 9. Steps S413 to S420 shown in FIG. 11 correspond to steps S311 to S318 shown in FIG. To do.

  In the present embodiment, the leg placement unit 5 is automatically adjusted in position in the longitudinal direction of the leg after the leg placement unit 5 is raised or lowered, and is positioned at that position. The position adjustment (contraction operation) is not performed even if the sole is simply separated from the sole contact portion 52c after the leg placement portion 5 is positioned. Therefore, unnecessary contraction of the leg mounting portion 5 is prevented, and convenience is ensured. Note that the position determined by the position adjustment process of the leg placement unit 5 does not have to be a position where the sole contact part 52c is exactly in contact with the sole, but a position slightly separated from the sole than the position. Alternatively, the fine adjustment may be performed so that the position where the sole contact portion 52c presses the sole is slightly deviated from the exact contact position.

When the “reclining” button 74e of the operation device 74 is pressed, the backrest 2 rises and the lowering operation of the leg rest 5 is performed in synchronization. The lowering operation here is the same as the lowering operation shown in FIGS. 10 and 11 (automatic position adjustment is also performed), and thus description thereof is omitted.
When the “reclined tilt” button 74f of the operation device 74 is pressed, the backrest 2 rises and the ascending operation of the leg rest 5 is performed in synchronization. The ascending operation here is the same as the ascending operation shown in FIGS. 8 and 9 (automatic position adjustment is also performed), and thus description thereof is omitted.

  The present invention is not limited to the above embodiment. For example, the leg placement part 5 is not limited to a structure comprising a plurality of leg holding members, and may be one in which one leg holding member moves so as to approach and separate from the seat part. Further, the floor detection sensor and the sole detection sensor are not limited to those exemplified in the embodiment, but may be sensors using other methods.

According to the reference invention , the floor detection sensor can detect whether or not the leg placement unit is in contact with the floor.
