An annular track 24 is configured between the two protruding walls 21 and 22 so as to correspond with the processing circuit 104 of the upper cover 1, and furhter provides a hook support for a fastening mount 3, whereby hook clasps 31 are symmetrically configured on an inner edge of the fastening mount 3, and a mount cavity 32 is defined on an upper face of the fastening mount 3. Gaps 321 are defined in the mount cavity, and a hook portion 322 is defined on each edge extremity of the gaps 321, thereby upon mounting a magnetic component 33 in the mount cavity 32, the hook portions 322 securely hook and thereby fasten down the magnetic ocmponent 33, and the hook clasps 31 further hook down the fastening mount 3 to the track 24.
  • [0020]
    After assembling the aforementioned components, and fitting together the upper cover 1 and lower cover 2, the twist disc 100 is thereby constructed. Upon a user standing atop the twist disc 100, twisting of the twist disc is realized by the ball bearings sliding along the slide tracks 102 and 103, thereby achieving effectiveness of twisting exercise. Furthermore, when twisting, sliding past of the magnetic component 33 of the fastening mount realizes a sensor for a magnetic spring switch 121 of the processing circuit 104, and in accordance with signals received from the sensor the processing circuit 104 displays such data as number of twisting motions, time, and so on, on the LCD 17 or vocalizes sound thereof.
  • [0021]

While the user is twisting the twist disc 100, the processing circuit 104 configured on the upper cover 1 slides left and right past the fastening mount 3, thereby the magnetic component 33 configured on the fastening mount 3 induces a response in the magnetic spring switch 121. Subsequently, on each detection of a response in the magnetic spring switch 121, the processing circuit 104 converts the response signal into related data including number of times a twist has occured, time, and so on, and diaplays such data on the L.C.D. 17, thereby allowing the user to clearly view status of a exercise routine.
  • [0023]
    FIG. 7 shows a circuit diagram of a preferred embodiment of the present invention. A microprocessing unit 11, a meter unit 12, a display unit 13, and mode setting buttons 14 and 15 are all configured within the twist disc 100 of the present invention. Among which, the microprocessing unit 11 further comprises a sound circuit 111. The meter unit 12 is constructed to include the magnetic spring switch 121 and a magnet 122. The mode setting buttons 14, 15 are adapted to enable switching between mode settings, whereby when the twist disc 100 is in a twisting motion, the magnetic spring switch 121 of the meter unit 12 senses signals from the twisting motions, and displays data on the display unit 13 disclosing calorific value consumed, time, speed and number of twisting motions. Upon reaching preset data figures, sound or music is transmitted through a sound circuit 111 for broadcasting. Prior to usage, a user can first make a selection with the mode setting button 14, and as long as the selection “normal” is made, when twisting motion occurs on the twist disc 100, each twisting motion of the twist disc 100 will trigger the meter unit 12 to forward a signal to the microprocessing unit 11 to register one twisting motion, and the microprocessing unit 11 will accumulate the number of twisting motions accordingly thereafter. At the same time, the microprocessing unit 11 will commence recording time elapsed once the first twisting motion of the twist disc 1 occurs, and continue to record such until twisting motions of the twist disc 100 ceases. The microprocessing unit 11 will register number of twisting motions and convert this number to a calorific value consumed and speed of the twist disc 100, including outputting the number of twisting motions and time elapsed so as to display such on the display unit 13. Furthermore, the microprocessing unit 11 records aforesaid data figures for use as comparison the next time the twist disc 100 is used, thereby allowing the user to learn whether or not they have made any progress. Moreover, a function is enabled that allows making mode selections of what to record (maximum number of twisting motions, maximum length of time, fastest speed), and accumulation (number of twisting motions, time, calorific value).
  • [0024]
    In addition, during a course of twisting motions on the twist disc 100, when the microprocessing unit 11 reaches a set default number (such as 5 times, 10 times, 20 times . . . ), control is thereby enabled for the sound circuit 111 to output a sound signal corresponding to such default number of twisting motions, therethrough an amplifying circuit amplifies the sound signal, which a speaker 16 thereupon broadcasts. The user can thus know of the present number of twisting motions they have already performed on the twist disc 100.
  • [0025]
    The sound mode setting button 15 can also be set, whereby during a course of twisting motions, when exercise from the twisting motions has reached a preset calorific value consumption, the sound circuit 111 transmits a sound signal, therethrough an amplifying circuit amplifies the sound signal, which the speaker 16 thereupon broadcasts. The user is then informed calorific value consumed is approximately equal to calorific value of what foodstuff, thereby allowing the user to know more specifically effectiveness of their exercise routine.
  • [0026]
    In accordance with speed of twisting motions, computation is carried out regarding extent of the exercise routine. If the exercise routine is too inactive, the sound circuit 111 transmits a sound signal; therethrough an amplifying circuit amplifies the sound signal, which the speaker 16 thereupon broadcasts urging the user on and making fun of the user. If the exercise routine is too intense, the sound circuit 111 transmits a sound signal, therethrough an amplifying circuit amplifies the sound signal, which the speaker 16 thereupon broadcasts warning the user to pay heed to their rigorous exercise. The user is thereby given a sense of intimacy, and a feeling that there is always someone at their side fostering care and attention.
  • [0027]
    In addition, the sound mode setting button 15 can also be set, whereby during a course of twisting motions on the twist disc 11, when the microprocessing unit 11 reaches a set default time (such as 15 seconds, 30 seconds, 45 seconds, 1 minute . . . ), control is thereby enabled for the sound circuit 111 to output a sound signal corresponding to such default time of twisting motions, therethrough an amplifying circuit amplifies the sound signal, which the speaker 16 thereupon broadcasts. The user can thus keep track of exercise time during their exercise routine, and thereby avert problems of under exercise or over exercise.
  • [0028]
    Music can also be broadcasted by switching of a button, allowing listening of music while performing twisting motions on the twist disc 100. Under accompaniment of intense rhythmic music, the more the user twists the more enjoyable the exercise routine becomes, and the more it invites enjoyment, thereby achieving objective of a healthy and fit body.
  • [0029]
    In conclusion, the present invention utilizes the magnetic spring switch 121 in coordination with the magnetic component 33, such that when the twist disc 100 is in usage data related to the exercise routine is displayed, thereby actualizing a design of practicability. It is therefore readily apparent that the present invention is a new and original invention, accordingly a patent application is proposed herein.
  • [0030]
    It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
