CYCLING APPARATUS

Technical Field

[1] The present invention is regarding the sporting apparatus for cycling exercise with pedaling of the bicycles, stepping exercise and/or elliptical exercise in oval that is similar to walking. In general, the sporting apparatus is equipped with left crank, right crank and pedals on the one end of the crank; main body that is placed on the horizontal plane (or ground) where left and right crank swivel is formed; the other end of the crank that works as the swivel to the crank swivel, the other end of each of the left and right crank that is connected for the circular movement in mutual inter- working of the left and right crank and the saddle that is equipped to the top of the apparatus with the necessity.

[2] With the structure of the cycling apparatus, a user acquires the effect of pedaling the cycle with circular movement of right and left feet following the exterior track of circling movement for the left and right crank. Background Art

[3] The present invention is regarding the sporting apparatus for cycling exercise with pedaling of the bicycles, stepping exercise and/or elliptical exercise in oval that is similar to walking. In general, the sporting apparatus is equipped with left crank, right crank and pedals on the one end of the crank; main body that is placed on the horizontal plane (or ground) where left and right crank swivel is formed; the other end of the crank that works as the swivel to the crank swivel, the other end of each of the left and right crank that is connected for the circular movement in mutual inter- working of the left and right crank and the saddle that is equipped to the top of the apparatus with the necessity.

[4] With the structure of the cycling apparatus, a user acquires the effect of pedaling the cycle with circular movement of right and left feet following the exterior track of circling movement for the left and right crank.

[5] However, the track only allows the exercise of legs in the direction of top, bottom, front and back without exercise in upper body of a user. Therefore, user only develops the limited muscles; feels the boredom with exercise for just legs. Disclosure of Invention

Technical Problem

[6] Accordingly, the present invention intend to provide an apparatus which can double effect of the exercise because body of the user moves left and right with the indoor cycling exercise and stepping exercise; stimulate new muscles; overcome a boredom in

simple cycling exercise with the movement in direction of left and right. Technical Solution

[7] The present invention is for crank axis, the rotating axis of the cycling exercise, to make axial rotations having a tilt (tilt not horizontal or vertical) against the horizontal plane to allow not only the cycling exercise but also the exercise in that body of user moves left and right.

Advantageous Effects

[8] According to the present invention, effect of the exercise doubles since body of the user moves left and right with the indoor cycling exercise, stepping exercise and/or elliptical exercise; new muscles are stimulated; boredom in simple cycling exercise is relieved with the movement in direction of left and right.

Best Mode for Carrying Out the Invention [16] In reference to FIG. 1 or FIG. 3, the present invention is structured with main body

(10); the main body that is structured with supporting frame (11), left crank swivel (12,

12L) and right crank swivel (12, 12R) and it is either placed on horizontal plane or supported with fixation on certain structure. [17] It is desirable for left crank (20, 20L) and right crank (20, 20R): the one end (21,

2 IR, 21L) of the crank (20) to work as swivel making a rotation with a tilt against the horizontal plane to the crank swivel (12, 12L, 12R) and the tilt shall make left crank

(20L) and right crank (20R) to be mutual V type (including reverse V type) with axial bond of exterior of the crank swivel toward the top. [18] Material Linkage (30); the material linkage is processed for the one end of the left crank (20, 20L) and the right crank (20, 20R) to rotate with mutual refraction, the

material linkage can work as refracting material (31) such as wire that mutually connects the one end of the left crank and the right crank and also shall work as universal joint, namely the material joint (32).

[19] Left pedal (40, 40L) and right pedal (40, 40R): the pedal (40) works as swivel rotating with a tilt against the other end (22, 22L, 22R) of the crank thus the tilt allows the pedal (40) to be horizontal when the crank rotates based on the titled axial bond after the axial bond with the other end of the crank to distance it to the lower part of the pedal as it moves from the exterior (41, 4 IL, 41R) to the interior (42, 42L, 42R) of the pedal.

[20] At the moment, user may be seated and do exercise by holding the handle part with attachment of saddle (50) and/or handle part (60) to the main body (10) as presented in FIG. 4.

[21] In addition, the provision of pedaling exercise in stepper type as FIG. 5 presenting the previous stepping exercise is available with the crank (20) and at least 1 pair of the refracting element (30) front and back; axial bond of the other end (22) of the crank in same method as above toward front and back (4OF, 40B) of the pedal (40), namely in longitudinal direction.

[22] As FIG. 6 presents the structure that allows the exercise containing the walking exercise in oval previously called as elliptical, it is equipped with the movement swivel (12) in front and/or back of the main body (10); equipped with the left handle stem (70, 70L) and right handle stem (70, 70R): handle (71) on top of the handle stem (70), makes middle of the handle stem to bond (72) to the movement swivel and bottom of the handle stem to bond (73) to the front (40F) or back (40B) of the pedal. Each of the bonds may be the axial bond with the rotating axis or refracting bond using the refracting materials to adapt to the movement of the pedal (40).

[23] Bond (72) in the middle of the movement swivel (12) in FIG. 7A and FIG. 7B is placed of pipe (72') and works as swivel (72Ax) from the movement swivel (12) to allow front and back movement at exterior of the pipe and adaptation to the front and back movement, cycling rotation movement of the pedal (40) and conversion of direction with movement toward left and right by the tilt are available with the pivot bond (72Pv) inserting the handle stem (70) to its inside.

[24] Also, the bond (72) with the pedal (40) and the handle stem (70) in FIG. 7A and

FIG. 7C may perform circular movement to the left and right by adding the axial bond (72Ax) available of front and back movement and pivot band (73Pv) with same method presented in the FIG. 7B. At the moment, bearing (Br) can be used and the bearing also may be used in all axial bonds.

Mode for the Invention

[26] The present invention is structured with main body (10); the main body that is structured with supporting frame (11), left crank swivel (12, 12L) and right crank swivel (12, 12R) and it is either placed on horizontal plane or supported with fixation on certain structure.

[27] It is desirable for left crank (20, 20L) and right crank (20, 20R): the one end (21,

2 IR, 21L) of the crank (20) to work as swivel making a rotation with a tilt against the horizontal plane to the crank swivel (12, 12L, 12R) and the tilt shall make left crank (20L) and right crank (20R) to be mutual V type (including reverse V type) with axial bond of exterior of the crank swivel toward the top.

[28] Material Linkage (30); the material linkage is processed for the one end of the left crank (20, 20L) and the right crank (20, 20R) to rotate with mutual refraction, the material linkage can work as refracting material (31) such as wire that mutually connects the one end of the left crank and the right crank and also shall work as universal joint, namely the material joint (32).

[29] Left pedal (40, 40L) and right pedal (40, 40R): the pedal (40) works as swivel rotating with a tilt against the other end (22, 22L, 22R) of the crank thus the tilt allows the pedal (40) to be horizontal when the crank rotates based on the titled axial bond after the axial bond with the other end of the crank to distance it to the lower part of the pedal as it moves from the exterior (41, 4 IL, 41R) to the interior (42, 42L, 42R) of the pedal.

[30] At the moment, user may be seated and do exercise by holding the handle part with attachment of saddle (50) and/or handle part (60) to the main body (10) as presented in FIG. 4. Industrial Applicability

[31] According to the present invention, effect of the exercise doubles since body of the user moves left and right with the indoor cycling exercise, stepping exercise and/or elliptical exercise; new muscles are stimulated; boredom in simple cycling exercise is relieved with the movement in direction of left and right.
