  • the present invention relates to a rocking-type exercise device for applying an exercise load to a user sat on a seat by subjecting the seat to rocking movement.
  • rocking-type exercise devices for applying an exercise load to a user sat on a seat by subjecting the seat to rocking movement.
  • the rocking-type exercise devices are simple and convenient exercise machines that can be used by anybody from children to old persons.
  • the rocking-type exercise devices have been spread to rehabilitation-purpose medical institutions and then to general households.
  • One typical prior art example of the rocking-type exercise devices is disclosed in, e.g., Japanese Patent Laid-open Publication No. 2006-149468 .
  • a pressure sensor or the like is provided in at least one of, e.g., the upper surface of the seat, the side surface of the seat (or the saddle flap) and the inside of the stirrup.

  • the present invention provides a rocking-type exercise device capable of accurately leading the user's exercise posture to a target exercise posture.
  • a rocking-type exercise device including:
  • feedback stimulus denotes a stimulus for guiding the user's exercise posture by at least one of a sound, an image, a seat operation amount and a seat operation pattern.
  • feedback stimulus will be used in this sense.

  • step S340 If the user selects the termination of feedback control using a switch not shown (or if YES in step S340), the microcomputer 17 ceases to output the voice as a feedback stimulus and stops the feedback control for guiding the exercise posture by a voice (step S350). In contrast, if the user does not select the termination of feedback control (or if NO in step S340), the flow proceeds to step S400 already described in respect of the foregoing embodiment.
  • the microcomputer 17 ceases to output the feedback stimulus (or the voice). This makes it possible for the user to safely perform an exercise in a favored posture with no overwork, instead of compelling the user to do an exercise at the target value.
  • only one sensor i.e., the pressure sensor ⁇
  • the voice as a feedback stimulus is outputted through the speaker 68 depending on the difference between the detected information and the target value.
  • a plurality of sensors e.g., the pressure sensor ⁇ and the angle sensor ⁇ may be used in outputting the voice as a feedback stimulus through the speaker 68.
  • the microcomputer 17 may output feedback stimuli (e.g., voices) for improving the detected information of the pressure sensor ⁇ as illustrated in Fig. 14 .
  • feedback stimuli e.g., voices
  • the user can accurately take a target exercise posture (corresponding to the target value).
  • a priority order is applied to the respective sensors ⁇ and ⁇ and voices as feedback stimuli are outputted through the speaker 68 in the priority order.
  • the user may be urged to change his or her posture from the state illustrated in Fig. 15A in which the lower half of the user's body (or the legs) is stretched and propped to the state illustrated in Fig. 15B in which the lower half of the user's body (or the legs) is bent.
  • it is necessary to urge the user to reduce the angle of the knees prior to reducing the pinching force of the thighs. If the knee angle is not equal to the target value "small" as shown in Fig.
  • a voice as a feedback stimulus for improving the detected information (or the representative value S n ) of the angle sensor ⁇ is outputted through the speaker 68, thereby urging the user to pay attention to the knee angle.
  • a voice as a feedback stimulus for improving the detected information (or the representative value S n ) of the pressure sensor ⁇ s outputted through the speaker 68.
  • the pressure sensor ⁇ and the angle sensor ⁇ are given a priority order in which to output feedback stimuli (e.g., voices) regardless of the difference between the detected information of the respective sensors and the target value.
  • the feedback data selection table shown in Fig. 16A may be changed to a feedback data selection table illustrated in Fig. 16B , which indicates the voice data containing the emotion-appealing information for encouragement, or a feedback data selection table depicted in Fig. 16C , which indicates the voice data containing the emotion-appealing information for appreciation.
  • Fig. 16B a feedback data selection table depicted in Fig. 16B
  • Fig. 16C which indicates the voice data containing the emotion-appealing information for appreciation.
  • the content of the emotion-appealing information is changed depending on the difference between the target value and the detected information (or the representative value S n ). Use of this configuration helps prevent the feedback stimulus from becoming monotonous, which makes it possible to keep the user motivated.
  • a configuration by which to output a feedback stimulus specifying the names of components making contact with the user's bodily parts may be possible to employ a configuration in which the voice data of "let's lower the stirrup.wav", i.e., a voce record saying "let's lower the stirrup”, is selected when the user's posture is to be changed from the state illustrated in Fig. 17A , in which the legs are stretched, to the state shown in Fig. 17B , in which the shins are oriented vertically downwards.
  • a configuration by which to output a feedback stimulus mentioning the user's bodily parts may be employed.
  • the voice data of "further stretch the knees.wav" illustrated in Fig. 19 i.e., a voice record saying "further stretch the knees" is selected when the user's posture is to be changed from the state illustrated in Fig. 17C , in which the shins are bent, to the state shown in Fig. 17B , in which the knees are stretched to some extent.
  • a configuration by which to select the voice data of "stretch the knees slowly.wav” illustrated in Fig. 20 i.e., a voice record saying "stretch the knees slowly”.
  • the feedback stimulus is outputted in the form of a voice according to the foregoing embodiment, the present invention is not limited thereto.
  • the feedback stimulus may be a sound such as background music or the like rather than the voice.
  • the feedback stimulus may be outputted in the form of an image or the like.
  • control circuit 62 may be conceivable for the control circuit 62 to control the seat rocking mechanism 12 in such a manner as to reduce the operation speed of the seat 13 or to make the rocking operation angle of the seat 13 substantially horizontal, thereby lessening the exercise load. This may be notified to the user by a voice or through the display of an image or the like.
  • the incidental effects is to change the sound volume, sound quality, sound pitch and peak frequency of a voice or background music outputted as a feedback stimulus. It is preferred that the degree of these effects varies with the difference between the target value and the detected information (or the representative value S n ). Use of this configuration helps prevent the feedback stimulus from becoming monotonous, which makes it possible to keep the user highly motivated.
  • the detector units may include, e.g., an image sensor y indicated by a dot line in Fig. 6 .
  • the representative value S n refers to the average value obtained by sampling, for a specified time period, the detected information outputted from the pressure sensor ⁇ .
  • the present invention is not limited thereto.
  • the representative value S n may be a peak value rather than the average value.
  • the seat 13 is operated in such a way as to describe the numeral "8", consequently performing a rocking motion just like horse riding.
  • the present invention is not limited thereto.
  • the values of the threshold and the target and the like are exemplified in the embodiments described above, but the present invention is not limited thereto.
  • the threshold value and the target value and the like may be varied as necessary.
