Description:
JUMPING MACHINE FOR ROPE-SKIPPING Technical Field The present invention relates generally to an apparatus for substitute jumping exercise for jumping rope, and more particularly to an apparatus for substitute jumping exercise for jumping rope that is operated to allow users to exercise using a light beam instead of a rope in the same manner as a jump rope.

Background Art A conventional jump rope includes two handles, and a rope that connects the two handles and connected to the two handles to be rotated.

The jump rope allows users to exercise in such a way that the users rotate handles thereof and jump the jump rope to prevent their legs from being caught by the jump rope. Although jumping rope using the jump rope is advantageous in that it does not require an excessive space and is useful to physical training, it is difficult to jump rope in houses having low ceilings and lamps due to the rope rotating higher than the height of users. Additionally, vibrations generated during jumping rope may cause noise pollution indoors, so jumping rope is usually performed outdoors. Accordingly, the conventional jump rope is limited in that it is difficult to use the jump rope indoors.

Additionally, the environments for jumping rope are limited in that many outdoor spaces are paved with cement or asphalt. Accordingly, the intensity of the impact exerted on the knees and joints of users is high, thus doing harm to the body.

<Description of reference numerals of principal elements> 100 : apparatus for substitute jumping exercise 110 : frame 120: jumping board structure 140: rotating beam projecting unit 150 : control panel 160 : sound output unit 180 : main control unit 200: handle unit

Best Mode for Carrying Out the Invention An apparatus for substitute jumping exercise for jumping rope according to a preferred embodiment of the present invention is described in detail with reference to the accompanying drawings below.

FIG. 1 is a perspective view of the apparatus for substitute jumping exercise for jumping rope according to the preferred embodiment of the present invention.

With reference to the drawing, the apparatus for substitute jumping exercise for jumping rope 100 includes a stepping body and a rotating beam projecting unit 140 attached to the stepping body. Reference numerals 150 and 200 designate a control panel and handle units, respectively.

The stepping body includes a frame 110 and a jumping board structure 120 disposed to be fitted into the frame 110. Reference numeral 113 designates support rods that are mounted on the frame 110 to support the control panel 150 at a height that can provide information and convenience of manipulation to a user in a standing state. Of course, the control panel 150 may be provided separately from the frame 110, and may be adapted to communicate with a main control unit 180 (will be described later; see FIG. 6) in a wireless manner.

The jumping board structure 120 preferably includes a shock absorbing body to reduce shock when a user jumps.

More preferably, the jumping board structure 120 is fabricated to be lifted and lowered so that the user easily performs jumps while easily detecting the rhythm of jump exercise.

Referring to FIG. 2 showing the jumping board structure 120 according to the preferred embodiment of the present invention, the jumping board structure 120 is constructed so that a base body 121, a shock absorbing body 122, an upper body 123, a jump detecting unit 124 and a closing layer 125 are sequentially stacked one on top of another.

The base body 121 is rotatably mounted on the frame 110 through the use of hinges 127.

The shock absorbing body 122 is made of material having a high shock absorbing capacity, such as porous material, for example, sponges or springs.

The upper body 123 is interposed between the shock absorbing body 122 and the jump detecting unit 124 to distribute the weight of the user across the shock absorbing body 122.

The jump detecting unit 124 can be implemented in various manners to detect the number and times of jumps of the user who performs jumping exercise on the jumping board structure 120.

Referring to FIG. 3 in which an example of the jump detecting unit 124 is shown, the jump detecting unit 124 includes a first conductive plate 124c, an insulating plate 124b and a second conductive plate 124a.

The first conductive plate 124c is provided with a plurality of touch pads 124cl that are connected to each other by conductive material to be downwardly moved by pressure from the above.

The insulating plate 124a is made of insulating material, and is provided with a plurality of holes 124bl at positions corresponding to those of the touch pads 124cl to pass the touch pads 124c1 of the first conductive plate 124c therethrough.

The second conductive plate 124a is made of conductive material, and disposed below the insulating plate 124cl. The first conductive plate 124c and the second conductive plate 124a are connected to a circuit that is designed to output a corresponding signal depending upon whether the touch pads 124cl are brought into contact with the second conductive plate 124a through the holes 124bl of the insulating plate 124b.

When the user stands on and is supported by the jumping board structure 120, the first and second conductive plates 124c and 124a are electrically connected to each other and the jump detecting unit 124 outputs a signal corresponding to a source voltage Vcc. When the user jumps and is separated

from the jumping board structure 120, the first and second conductive plates 124c and 124a are electrically separated from each other and the jump detecting unit 124 outputs an open signal. A combination of the first and second conductive plates 124c and 124a is equivalent to a switch element, and the circuit may be constructed in different manners, including the manner in which a high signal and a low signal are selectively output depending upon whether the first and second conductive plates 124c and 124a are brought into contact with each other. The construction of these circuits are disclosed on a textbook level, so a detailed description thereof is omitted.

The closing layer 125 is made of appropriate material in consideration of the appearance and protection of the jump detecting unit 124. Preferably, the closing layer 125 is made of rubber that has shock-absorbing and insulating capacities.

The jumping board drive unit that is a means for lifting and lowering the jumping board structure 120 can be implemented in various manners.

As an example, the jumping board drive unit 130 includes an eccentric cam 131 and a driving power source that drives the eccentric cam 131.

The eccentric cam 131 supports the lower surface of the jumping board structure 120 at a position spaced apart from the hinge 127 of the jumping board structure 120, and is disposed to have eccentricity and be rotated.

The eccentric cam 131 is connected to the motor 134 through gears to be rotated in conjunction with the rotation of the motor (134). Reference numeral 132 designates a first gear formed on the rotating shaft of the eccentric cam, and reference numeral 133 designates an intermediate gear that intermediates between a gear formed on the rotating shaft of the motor and a first gear (132).. Further, reference numeral 111 designates a stopper that limits the distance of the lowering of the jumping board structure 120.

Of course, the means for lifting and lowering the jumping board structure 120 may employ various manners, such as a telescopic piston manner, besides the cam drive manner.

The rotating beam projecting unit 140 can be mounted on a side of the stepping body, or on the rear surface of the control panel 150 (not shown). The rotating beam projecting unit 140 includes a light source and a beam rotating means for rotating a beam projected from the light source. The rotating light beam generated by the rotating beam projecting unit (140) provides the same visual impression as a rotating jump rope.

Preferably, the rotating beam projecting unit 140 prevents the light beam from reaching the user's eyes and limits the projecting angles of the rotating light beam to a certain range of angles, that is, the visible angles of the user.

To this end, the casing of the rotating beam projecting unit 140 is provided with a light transmitting window 140a that is formed to be suitable for the limited projecting angles. The remaining portion of the casing of the rotating beam projecting unit 140 excepting for the light transmitting window 140a is formed to block the light.

Various light sources, such as a light-emitting diode, a laser diode, a halogen lamp, may be used as the light source. Of course, the light source may be implemented so that one or more light sources are arrayed to project a converged or diverged light beam.

A beam rotating means of the rotating beam projecting unit 140 may be implemented in various manners.

For a first embodiment, the beam rotating means may be implemented in the manner of rotating the light source. As an example of this case, as shown in FIG. 4, the rotating beam projecting unit 140 includes a light source 141a, a source support 141b on which the light source 141a is supported, and a motor 145 connected to the source support 141b to rotate the source support 141b. When the rotating shaft 146 of the motor 145 is fixedly connected to the source support 141b on which the light source 141 a is mounted, the light source 141 a is rotated in conjunction with the rotating movement of the motor 145.

In this case, a battery mounting structure of a flashlight can be applied to the source support 141b so that batteries are accommodated in the source support

141 b and power can be supplied to the light source 141 a.

In the case where power is adapted to be supplied from the outside differently from the above-described case, outside power lines 148b are configured to supply power to the light source 141a regardless of the rotation of the source support 141b. As an example of this case, as shown in FIG. 4, two ring-shaped terminals 142 electrically separated from each other and connected to the terminals of the light source 141a are formed around a cylindrical terminal unit 142 extending around the rotating shaft 146b by a certain length, and power supply intermediate terminals 148a connected to the outside power lines 148b are disposed to come in contact with the ring-shaped terminals 143 and 144. The power supply intermediate terminals 148a are formed of steel conducting plates to have tension in the direction of pressing the ring-shaped terminals 143 and 144, or of brush-type terminals in which a plurality of stands made of elastic conducting material are tied into bundles to be electrically conducted to each other. Reference numeral 149 designates a support plate that is used to secure the power supply intermediate terminals 148a to the casing.

Meanwhile, a second example of the rotating beam projecting unit 140 may be implemented by a fixedly mounted light source (not shown) and a rotating and reflecting mirror (not shown). In this case, the rotating and reflecting mirror is mounted so that the projecting angle is gradually changed by the rotation of the driving power source such as a motor (not shown).

Referring to FIG. 1, the handle units 200 are gripped to increase the impression of actual jumping rope.

The handle units 200 each include a handle part extending by a length sufficient to be gripped by the user and a rotating part rotatably connected to one end of the handle part.

The rotating part is formed to have a weight to such a degree that the user feels the weight that is felt by the user when the user rotates a conventional jump rope including a rope. Preferably, as shown in FIG. 5, a relatively heavy weight 204 is contained in the rotating part 203 perpendicularly and rotatably

connected to the handle part 201 at a position offset from a rotating center.

A rotation detecting means for detecting the rotation of the rotating part 203 is preferably mounted on the rotating part 200. The rotating detecting means may be implemented in various contact and non-contact manners.

For example, as shown in FIG. 5, the rotation detecting means may be implemented by employing an interfering protrusion 231 and an interference detecting sensor 232 positioned to be interfered with by the interfering protrusion 231. In this drawing, reference numeral 220 designates a printed circuit board of a rotating rod control unit that wirelessly transmits a rotation detecting signal corresponding to a signal output from the interference detecting sensor. In this case, reference numerals 231 and 232 designate rotation number detecting units.

Alternatively, the rotation detecting means may be implemented by installing a light-emitting element and a light receiving element at a side of the rotating part 200 offset from the center of rotation of the rotating part 200 and at a corresponding side of the handle part 201. Of course, the rotation detecting means may be implemented in various manners.

A key input unit and a display unit are integrated in the control panel 150 and the rotating beam injecting unit is attached to the rear surface of the control panel 150, which will be described in detail.

The control block diagram of the apparatus for substitute jumping exercise for jumping rope is illustrated in FIG. 6.

Elements having the same functions as elements shown in the above- described drawings are denoted by the same reference numerals.

Referring to the above-described drawings, the control system of the apparatus for substitute jumping exercise for jumping rope includes a main control unit 180, a control panel 150, a receiving unit 170 and a sound output unit 160.

In the case where the control panel 150 is fabricated in a wireless manner, a transmitting unit (not shown) besides the receiving unit 170 is additionally connected to the main control unit 180.

A variety of keys are provided on the key input unit 150 of the control panel 150 to set exercise conditions.

An example of the key input unit 151 is described with reference to FIG.

7.

Referring to FIG. 7, the key input unit 151 includes an exercise time setting key 151 a, a level setting key 151b, a target jump number setting key 151c, an up/down key 15 Id and 15 1 e, a power on/off key 15 If, a reset key 151g and a start/stop key 151 h.

The exercise time setting key 151a is used to set exercise time. The adjustment of time is performed using the up/down key 15 Id and 15 ive.

The level setting key 151b is used when one level is selected in the case where the rotational speeds of a light beam are divided into 10 stages and these stages are provided for selection. The adjustment of a level is performed using the up/down key.

The target jump number setting key 151c is used to select the target number of jumps for exercise.

The up/down keys 151d and 151e are used to adjust exercise time, a level and the target number of jumps.

The reset key 151g is used to reset previously set exercise conditions when the user resumes exercise.

Although mounted on the sides of the control panel 150 and not shown, the control panel 150 further includes a sound output unit on/off key, a rotating beam projecting unit on/off key and a mode selecting key.

The sound output unit on/off key is provided to be used when the output of sound is not desired, and the rotating beam projecting unit on/off key is provided to be used when the projection of a light beam is not desired.

The mode selecting key is the key that is used to select one from a plurality of modes.

Preferably, the apparatus of the present invention supports a first mode in which, when erroneous jumps are generated, that is, the jump timing of the user

does not coincide with a set rotational speed, the rotational speed of the light beam, the lifting and lowering speed of the stepping body or the flickering speed of a sequential light-emitting display unit (will be described) is automatically adjusted in conformity with the exercise speed of the user, a second mode in which the function of automatically adjusting the rotational speed in conformity with the exercise speed of the user is excluded from the functions of the first mode and the apparatus is operated according to exercise conditions set by the user, and a third mode in which only accumulated times and the number of jumps are counted if a start button is pushed according to exercise conditions set as a default.

At the time of manipulating a stop button or ending exercise depending upon set exercise conditions, the calculated numbers of correct jumps and erroneous jumps are displayed on the display unit 153.

The display unit 153 displays various information under the control of the main control unit 180.

Referring to FIG. 7 in which a preferred embodiment of the display unit 153 is enlarged, the display unit 153 includes display windows 153a and 153b displaying characters or numbers and a sequential light-emitting display unit 153c.

The upper one 153a of a plurality of display windows 153a and 153b displays exercise results or other information, and the lower one 153b displays exercise conditions set by the user while being divided to correspond to the positions of keys.

Reference numeral 153d is a lamp for indicating the display of the number of correct jumps when the number of correct jumps is displayed on the display window 153a, and reference numeral 153e is a lamp for indicating the display of the number of erroneous jumps.

The sequential light-emitting display unit 153c performs a function similar to that of the rotating beam projecting unit 140, and is operated so that light-emitting devices arranged in lines from the upper end thereof to the lower

end thereof are sequentially lit or flickered in patterns, which are preset to correspond to rotational speeds, according to rotational speeds under the control of the main control unit 180. The sequential light-emitting display unit 153c provides a visual impression in which the user seems to rotate a jump rope using light sequentially lit in the direction of the line of light-emitting devices.

Accordingly, the sequential light-emitting display unit 153c allows the user to exercise even when the operation of the rotating beam projecting unit 140 is stopped.

The sound output unit 160 is designed to output stored various sounds under the control of the main control unit 180.

Preferably, the sound output unit 160 is operated to provide the effect sounds of jumping rope under the control of the main control unit 180.

Accordingly, whenever the light beam is rotated, a sound generated when the jump rope collides with a floor while being rotated and a wind sound generated when the jump rope is rotated are output.

Further, the main control unit 180 is designed to control the sound output unit 190 to output an alarm when an erroneous jump is detected.

The receiving unit 170 outputs a rotation detecting signal received from the handle units 200 to the main control unit 180.

The rotational number detecting means 230 of the handle units 200 is a rotation detecting means that has been described through FIG. 5. When the rotation detecting signal is received by the rotation number detecting unit 230, the rotating rod control unit 220 outputs a signal corresponding to a rotation detecting signal.

The main control unit 180 controls the elements depending upon set exercise conditions and/or modes in response to a key input signal selected by the key input unit 141, determines whether jumps are erroneous based on signals detected by the jump detecting unit 124 and/or rotation signals output from the handle units 200, and displays determination results on the display unit 153.

For example, the main control unit 180 determines that a jump is correct

if the detected speed of the jump coincides with the rotational speed of the light beam, and determines that a jump is erroneous if the difference therebetween exceeds a preset error range.

Further, the main control unit 180 displays processed results corresponding to a selected mode when exercise terminates. For example, in the case where a second mode is set, the main control unit 180 displays the total number of jumps, the number of correct jumps obtained by subtracting the number of erroneous jumps from the total number of jumps, and the number of erroneous jumps on the display unit 153.

The determination of an erroneous jump is programmed to determine exercise conditions using part or all of conditions, such as the detection of a jump, the rotation angle of the rotating beam, the position of the jumping board drive unit and the generation of a rotation signal in the handle units. To this end, although not shown in the drawing, the apparatus may further include a sensor for detecting the position of the jumping board drive unit and a sensor for detecting the projection angle of the rotating beam.

Industrial Applicability As described above, the present invention provides an apparatus for substitute jumping exercise for jumping rope, which allows users to exercise indoors in the same manner as a jump rope by adjusting exercise timing using the rotation of a light beam, thus increasing opportunities to exercise by reducing a spatial limit and attracting interest in exercise.
