[24]
Mode for the Invention
[25] The preferred embodiments of the present invention will be described with reference to the accompanying drawings.
[26] Figure 1 is a perspective view illustrating a variable speed training apparatus of a continuous horizontal mechanism according to a first embodiment of the present invention. Figure 2 is a cross sectional view illustrating a variable speed training apparatus of a continuous horizontal mechanism according to a first embodiment of the present invention. Figure 3 is a side view illustrating a variable speed training apparatus of a continuous horizontal mechanism according to a first embodiment of the present invention. Figure 4 is a view illustrating an operation relationship of a variable speed training apparatus of a continuous horizontal mechanism according to a first embodiment of the present invention.
[27] As shown in Figures 1 through 4, the variable speed training apparatus Al of a continuous horizontal mechanism according to a first embodiment of the present invention comprises a frame 1, first and second rotation casings 3a and 3b which are opposed to each other and are installed in both sides of the body frame 1 at slanted angles, and a driving force transfer unit which connect the first and second rotation casings 3a and 3b. [28] As shown in Figure 2, the driving force transfer unit comprises a horizontal shaft 100 horizontally installed in an inner side of the body frame 1, a crank shaft 2 which is installed in the center of the body frame 1, with its end being connected with the horizontal shaft 100 through a connection member 9, a fixing gear 6 which is fixed in the crank shaft 2, a pedal shaft gear 7 connected with the pedals 4a and 4b, and a belt member 8 which connects the fixing gear 6 and the pedal shaft gear 7. [29] The connection member 9 is provided for transferring a rotational force of the horizontal shaft 100 to the crank shaft 2 and is preferably made of a universal joint.
Other types of connection units might be used. [30] As shown in Figure 3, a tensional force adjusting unit 12 is installed in the interiors of the first and second rotation casings 3a and 3b for controlling a rotational speed by means of a frictional contact with the belt member 8. [31] The tensional force adjusting unit 12 comprises an idle roller 10 contacting with the belt member 8, a bracket 110 for axially fixing the idle roller 10, an adjusting bolt 120 integrally formed in an end of the bracket 110, and a spring 11 disposed on an outer side of the adjusting bolt 120.
[32] The operation of the first embodiment Al of the present invention will be described.
[33] When a user steps on the pedals 4a and rotates the same with a certain force, the first rotation casing 3a rotates, and the left pedal shaft gear 7, the belt member 8 and the fixing gear 6 rotate, and the left crank shaft 2 rotates. So, the horizontal shaft 100 connected to a lower end of the left crank shaft 2 rotates. [34] As the right crank shaft 2 rotates, the second rotation casing 3b and the right pedal 4b rotate.
[35] Here, the left and right pedals 4a and 4b maintain a horizontal state all the time.
[36] The tensional force adjusting unit 12 might be adjusted so as to double an exercise effect by increasing an exercise load to the legs. [37] When the adjusting bolt 120 is tightened, the spring 11 is compressed, and the idle roller 10 closely contacts with the belt member 8, so an exercise load might be increased.
[38] So as to decrease the exercise load, it is needed to loosen the adjusting bolt 120.
[39] Figure 5 is a cross sectional view illustrating a variable speed training apparatus of a continuous horizontal mechanism according to a second embodiment of the present invention. [40] As shown in Figure 5, the variable speed training apparatus A2 of a continuous horizontal mechanism according to a second embodiment of the present invention comprises a body frame 1, first and second rotation casings 3a and 3b which are opposed to each other and are installed in both sides of the body frame 1 at a slanted angle and are equipped with pedals 4a and 4b, and a driving force transfer unit which rotatably connects the first and second rotation casings 3a and 3b. [41] The driving force transfer unit comprises first and second crank shafts 21 and 22 of which ends are eccentrically installed in the first and second rotation casings 3a and
3b, and the other ends are equipped with a bevel gear 200a for engagement, fixing gears 6a and 6b which are axially installed in the first and second crank shafts 21 and
22 and are provided in the first and second rotation casings 3a and 3b, a pedal shaft gear 7a connected to the pedals 4a and 4b, and a plurality of driven gears 80 which connect the fixing gears 6a and 6b and the pedal shaft gear 7a. [42] The first crank shaft 21 is further equipped with the tensional force adjusting unit
12a. [43] The tensional force adjusting unit 12a might be installed in the second crank shaft 22, and might be installed in both the first and second crank shafts 21 and 22. [44] The tensional force adjusting unit 12a includes an adjusting bolt 120a thread-engaged to the body frame 1, and a disk 123a which is formed in a rear end of the adjusting bolt
120a and is closely contacted with the first crank shaft 21. [45] The disk 123 a is formed in a semicircular shape while closely contacting with the outer surfaces of the first and second crank shafts 21 and 22.
[46] The operation of the second embodiment of the present invention will be described.
[47] When the user steps on the pedals 4a and 4b and rotates the same for exercise.
[48] When the user rotates the left pedal 4b by applying a load to the same, the first rotation casing 3a rotates, and the left pedal shaft gear 7a, the driven gear 80 and the fixing gear 6a rotate. The first crank shaft 21 of the left side is driven, and the second crank shaft 22 connected with the lower side of the first crank shaft 21 and the bevel gear 200a rotate. [49] As the second crank shaft 22 rotates, the second rotation casing 3b and the right pedal 4b rotate.
[50] Here, the left and right pedals 4a and 4b are in horizontal states all the time.
[51] The tensional force adjusting unit 12a is driven so as to double the exercise effect by increasing a load applied to the legs. [52] When the adjusting bolt 120a is tightened, the disk 123a friction-contacts with the first crank shaft 21, and the rotation is broke, so a lot of force is needed for rotation. [53] So as to decrease the load, the adjusting bolt 120a is loosened.
[54] Figure 6 is a cross sectional view illustrating a variable speed training apparatus of a continuous horizontal mechanism according to a third embodiment of the present invention. [55] As shown in Figure 6, the variable speed training apparatus A3 of a continuous horizontal mechanism according to a third embodiment of the present invention comprises a body frame 1, first and second rotation casings 3a and 3b which are opposed to each other and installed in both sides of the body frame 1 at slanted angles and include pedals 4a and 4b, and a driving force transfer unit for connecting the first and second rotation casings 3a and 3b and rotating the same.
[56] The driving force transfer unit comprises a horizontal shaft 100b which is horizontally installed in an inner side of the body frame 1, crank shafts 21 and 22 which are installed in the inner centers of the first and second rotation casings 3a and 3b with their ends being connected to the horizontal shaft 100b through the connection member 9b, a fixing gear 66b which is axially installed in the crank shafts 21 and 22, a pedal shaft gear 7b connected to the pedals 4a and 4b, a plurality of driven gears 80b which connect the fixing gear 66b and the pedal shaft gear 7b, and a motor apparatus M connected to the horizontal shaft 100b.
[57] The connection member 9b is a universal joint.
[58] A tensional force adjusting unit 12b is further installed in the interior of the first and second rotation casings 3a and 3b so as to adjust the rotation speed by means of a friction contact with the horizontal shaft 100b.
[59] Here, the tensional force adjusting unit 12b includes an adjusting bolt 120b thread- engaged to the body frame 1, and a disk 123b which is formed in a rear end of the adjusting bolt 120b and closely contacts with the horizontal shaft 100b.
[60] A control unit is further provided for selecting a manual mode and an automatic mode by controlling the on and off of the motor apparatus M.
[61] The motor apparatus M comprises a driving motor Ml, a decelerator M5 connected to the driving motor Ml, a driving pulley M2 connected to the decelerator M5, a driven pulley M4 axially engaged to the horizontal shaft 100b, a timing belt M3 which connects the driving pulley M2 and the driven pulley M4, and an electronic clutch M6 which engages or disengages the connection between the decelerator M5 and the driving pulley M2.
[62] The electronic clutch M6 is a known apparatus for switching the on and off of the driving force transfer, its description will be omitted.
[63] The operation of the third embodiment of the present invention will be described.
[64] The control unit is set in a manual mode, and the user steps on the pedals 4a and 4b, and rotates the same for exercise.
[65] When the user applies loads to the left pedal 4a, the first rotation casing 3a rotates, and the left pedal shaft gear 7b, the driven gear 80b and the fixing gear 66b rotate, and the left crank shaft 22 rotates, and the horizontal shaft 100b connected to a lower side of the left crank shaft 22 rotates.
[66] So, as the right crank shaft 222 rotates, the second rotation casing 3b and the right pedal 4b rotate as well. [67] The left and right pedals 4a and 4b are in horizontals states all the time.
[68] So as to double an exercise effect by increasing loads to the legs, it is needed to adjust the tensional force adjusting unit 12b. [69] When the adjusting bolt 120b is tightened, the disk 123 friction-contacts with the horizontal shaft 100b, so the rotation is broke, and more load is needed for rotation. [70] So as to decrease the load, it is needed to loosen the adjusting bolt 120b.
[71] The automatic mode is selected by operating the control unit, and the motor apparatus M is turned on, and the driving motor Ml rotates. [72] When the electronic clutch M6 is turned on, the rotational force of the driving motor
Ml rotates the driving pulley M2 and the timing belt M3 through the decelerator M5, and the driven pulley M4 and the horizontal shaft 100b rotate. [73] When the electronic clutch M6 is turned off, since the rotational force of the driving motor Ml is not applied to the driving pulley M2, the transfer of the rotational force to the horizontal shaft 100b is stopped. [74] The modified embodiment of the present invention will be described with reference to Figure 7. [75] As shown in Figure 7, a base 150 is installed in one side of the body frame 1, and a handle 160 is installed on an upper side of the base 150, and a cradle 170 is installed in the other side of the body frame 1. [76] An elastic unit 180 is installed in a lower side of the base 150, so an up and down twist motion can be obtained. [77] The elastic unit 180 includes a coil spring which connects the body frame 1 and the lower side of the base 150. [78] So, the user pedals the pedals 4a and 4b while holding the handle 160, and the user can perform a twisting motion using the handle while pedaling, so the exercise effect can be doubled. [79]
Industrial Applicability [80] According to the present invention, the crank pedals have the same inclinations, so it is possible to double the exercise effect during the pedaling of the pedals, and a waterproof function is provided, so it can be used in an outdoor. A saddle, a handle, various measurement units, and various exercise mechanism apparatuses can be combined and used. [81] As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
