    Best Mode
  • Hereinafter, a preferred first embodiment of the present invention will be described in detail with reference to the attached drawings.
  • Fig. 1a is a schematic perspective view showing a treadmill A having a virtual walking/running image display device according to a first embodiment of the present invention.
  • As shown in Figs. 1a and 1b, the treadmill A having the virtual walking/running image display device according to the first embodiment of the present invention is configured such that a controller body 300 is installed at the center of the top of a support 110 installed upright on the front portion of a treadmill body 100, and such that a panel monitor 121 for displaying the operating status of the treadmill and a selection panel unit 120 are installed on the controller body 300.
  • The selection panel unit 120 is implemented as a touch panel and has a setting unit 122 composed of a plurality of buttons.
  • As shown in Fig. 2, the controller body 300 includes a main control unit 310 configured to control various types of control units, a data storage unit 380 connected to the main control unit 310 and configured to store information about a plurality of virtual walking/running courses, a speed control unit 340 connected to the main control unit 310 and configured to analyze and convert information about each walking/running course, received from the data storage unit 380, in real time, and transmit signals to a belt drive motor 160 and an incline motor control unit 370, the incline motor control unit 370 connected to the main control unit 310 and configured to control incline motors when an incline mode appears in the virtual walking/running course information, a screen speed control unit 360 connected to the main control unit 310 and configured to output a real-time screen based on the virtual walking/running course information and to control the speed of the output screen, and the selection panel unit 120 provided with the setting unit 122.
  • That is, the selection panel unit 120 is electrically connected to the data storage unit 380 through the main control unit 310.
  • Further, the controller body 300 including the selection panel unit 120 having the panel monitor 121 and the setting unit 122 formed on the top thereof is connected to a video monitor 130, and then a virtual walking/running image display device B is implemented.
  • On the video monitor 130, a fragrance generation unit 130b and a speaker part 130a for generating sounds related to virtual walking/running courses in conjunction with the virtual walking/running courses are installed. The speaker part 130a is installed to output sounds in a wireless manner through earphones (not shown) inserted into the ears of the user. The fragrance generation unit 130b causes negative ions or phytoncide fragrance. As the video monitor 130, a monitor having a size of at least 30 inches must be installed so as to implement walking/running with a sense of realism.
  • In the present embodiment, the video monitor 130 is installed on the top of the support 110, but it may be installed to be supported by a separate stand (not shown) due to the problem of vibration. On the top of the support 110, electric fans 111 may be installed to dry the perspiration of the user or cool off the user.
  • Four incline drive motors 151 are installed at four corners of a running belt 150 on a deck 140, on which the user will stand and run, in the treadmill body 100 of the treadmill A. A driven shaft 150a is installed in the front portion of the running belt 150, and is installed to rotate using a power transmission belt 161 through which the rotary power of the belt drive motor 160 is transferred.
  • Guide handles 142 are installed upright on the front and rear portions of the top of the deck 140 of the treadmill body 100, and photo-sensors 143 are installed on the respective guide handles 142 and are configured such that a front photo-sensor 143 installed on the front guide handles 142 generates a warning sound against the danger of the forward approach of the user and such that a rear photo-sensor 143 senses the danger of the rearward fall of the user on the running belt 150 and generates a warning sound against the danger. Further, emergency stop switches 144 are formed on the front guide handles 142, thus stopping the operation of the running belt 150 in an emergency.
  • Fig. 2 is a configuration diagram showing a relation between the principal components of the treadmill body 100 having a virtual walking/running image display device according to a first embodiment of the present invention, and Fig. 3 is a block diagram showing a relation between the components of the virtual walking/running image display device according to the present invention.
  • A treadmill A having the virtual walking/running image display device is configured such that, when walking/running conditions, such as identification (ID), password, a walking/running course, and season, are entered using the setting unit 122 formed on the selection panel unit 120, and a walking/running start button is turned on, a walking/running information signal for a virtual walking/running course stored in the data storage unit 380 is transferred to the speed control unit 340. The speed control unit 340 analyzes and converts, in real time, information about each walking/running course received from the data storage unit 380, and then controls the belt drive motor 160 and the incline motor control unit 370.
  • The data storage unit 380 stores information about a plurality of virtual walking/running courses in addition to information such as the ID, password, and exercise history of the user, and such virtual walking/running course information includes images of the corresponding course and information about the height, curve, distance, etc. of each section of the corresponding course obtained by a Geographic Information System (GIS). For example, such virtual walking/running course information may be a Chuncheon marathon course, for which an image of a course for walking/running along the lakeside of Uiam Dam is produced with a length of about 4 hours (this is designated as a "Chuncheon full-course marathon stream"). Such a Chuncheon full-course marathon stream is produced to include eight divided sectional streams, each being played for about 30 minutes, and the user may load a desired sectional stream and use it for walking/running exercise. At this time, screen speed may be changed according to the doubled-speed of the video monitor 130 and may run along a marathon course of an hour (at double speed) or of an hour and a half (at 3x speed) by means of exercise taken for 30 minutes.
  • When the received information indicates an inclined or curved section based on the information stored in the data storage unit 380, the speed control unit 340 functions to operate individual incline drive motors 151 by transferring information about the corresponding section to the incline motor control unit 370 using a preset program while functioning to control the speed of the belt drive motor 160 to speed corresponding to the operation speed of the motors 151.
  • That is, the belt drive motor 160 is operated using a program preset to be operated slow on an uphill road and to be operated fast on a downhill road, in proportion to the degree of the inclination.
  • The screen speed control unit 360 analyzes the intensity of input power of the belt drive motor 160, converts the input power intensity into a signal, and controls the speed of the video monitor 130. In this way, the screen speed of the video monitor 130 may be associated with the rotational speed of the belt drive motor 160.
  • Further, the treadmill A having the virtual walking/running image display device has a double speed walking/running function. The double speed walking/running function executed by the image display device B allows the user to enjoy interesting exercise based on various experiences in such a way that, when the user selects the double speed walking/running function using the setting unit 122, the screen speed of the video monitor 130 in the treadmill A is increased by a designated scale factor regardless of the speed of the running belt 150 by the screen speed control unit 360 based on a preset program and then the user may walk/run along a long-distance course for a short period of time. Such a double speed walking/running function is operated using a double speed function used in a typical digital Television (TV) or Digital Versatile Disk (DVD).
  • For example, in the case of a Chuncheon marathon course image played using a double speed walking/running function, when it is desired to run, for 30 minutes, along the first sectional stream and the second sectional stream of a Chuncheon full-course marathon stream produced with a length of 4 hours, if a 2x speed function is selected and walking/running is conducted, the user may view an image corresponding to walking/running along a 1-hour marathon course as a 1-hour image corresponding to the first and second sectional streams has passed, by means of exercising for 30 minutes. Such a double speed walking/running function is implemented to extract only components configuring an-I picture from a specific location of a stream written in a large-capacity storage device with reference to the stored information, and transfer the extracted components to a Moving Picture Experts Group (MPEG) decoder, thus enabling walking/running to be conducted.
  • Fig. 4 is a flowchart showing an embodiment of the present invention.
  • When a user turns on the power of the treadmill A according to the present invention, enters his or her ID and password using the setting unit, selects a walking/running course, and starts walking/running, the data storage unit 380 initiates the generation of a data signal for the selected course. The speed control unit 340 that received the signal analyzes and converts the received signal in real time, and controls the speed of the belt drive motor 160, so that the belt drive motor 160 is operated depending on the controlled speed. The screen speed control unit 360 analyzes and converts an electrical signal from the input unit of the belt drive motor 160, and then controls the screen speed of the video monitor 130.
  • If the signal received from the data storage unit 380 is information about an incline mode related to an inclined section or a hill section, the speed control unit 340 separately transmits the signal to the incline motor control unit 370, and the incline motor control unit 370 analyzes and converts the received signal, and then controls the incline drive motors 151. That is, when a walking/running course is an uphill section, two front incline drive motors 151 are driven to be rotated to the right, so that the running belt 150 is forwardly and upwardly inclined, thus enabling the uphill section to be implemented. Simultaneously, the speed of the belt drive motor 160 is controlled to be low by the speed control unit 340, so that the speed of the running belt 150 becomes low while the screen speed is also controlled to be low by the screen speed control unit 360, thus completing the walking/running conditions of the virtual walking/running course.
  • In contrast, on a downhill road, operation contrary to that of the uphill road is performed, but the speed of the running belt 150 is controlled with the running belt 150 being forwardly and downwardly inclined at an angle close to a horizontal state on the downhill road, in consideration of the characteristics of the treadmill and the safety of the user.
  • Further, in a curved section, the speed control unit 340 transmits curve data received from the data storage unit 380, and the incline motor control unit 370 analyzes and converts the curve data, differently controls the heights of the four incline drive motors 151, and then implements a virtual curved inclined surface on the deck 140.
  • In the case of a right curved section, the running belt 150 is upwardly moved while the right incline drive motors 151 are combined and rotated to the right, so that the left surface of the running belt 150 is raised and the right surface of the running belt 150 is lowered, thus enabling the shape of the right curve to be implemented.
  • Further, even in a section in which an incline and a curve overlap each other, such functions may be combined to implement the section.
  • Furthermore, the present invention may store the ID, password, and personal walking/running history of the user in the data storage unit 380, may divide the entire long-distance course into sections and separately walk/run along the divided sections for respective dates in the case of long-distance course walking/running, and may store and refer to the walking/running history of the user for respective periods, thus enabling the amount of exercise for each person to be managed.
  • In the present invention, the video monitor 130 includes the function of dividing a single screen into two sub-screens 131 and 132 or more sub-screens and simultaneously displaying multiple screens depending on the user's selection, and then provides the function of allowing the user to watch a TV broadcast while viewing a virtual walking/running course image, by means of the function.
  • As described above, although the present invention has been described with reference to the specific preferred embodiment of the present invention, it should be understood that the present invention is not limited to the above embodiment and various modifications and changes can be implemented by those skilled in the art, without departing from the scope and spirit of the invention.
    • Industrial Applicability
  • Since, for a treadmill having a virtual walking/running image display device and a method of driving the treadmill according to the present invention, it is possible to repeatedly produce and execute the same product in normal treadmill manufacturing factories, the present invention may be considered to have industrial applicability.
