Description

  The present invention relates to an exercise training apparatus, and more particularly to a stepping machine capable of obtaining a double training exercise effect that allows a user to step and stretch muscles simultaneously.

  In general, an indoor training apparatus often imitates an outdoor motion operation mode so as to obtain outdoor training and a considerable training effect in a limited indoor space for the user. For example, a treadle machine (also called a stepping training device) is a type of exercise that imitates stepping by further matching the pedals that are stepped on both feet to alternate vertical movements by the stepping force of both feet of the user. And the purpose of training can be realized.

  In the conventional well-known stepping machine, the basic configuration is almost the same, and two alternating vertically movable pedals are mainly provided on one base, and the front ends of the two pedals are pivotally attached to the base. The two pedals are connected to the hydraulic cylinders respectively, and the damping action of the hydraulic cylinders causes the two pedals to move up and down relatively alternately and maintain the operation of the pedals in a coordinated manner. It becomes possible to obtain the effects of exercise and training that can mimic stepping.

  However, a similar stepping machine only moves the pedals up and down relative to each other, and the operation method is monotonous, not only boring, but the user always stretches the thigh muscles by stepping on the pedal with great force. The effects of exercise and training acquired are quite finite, so there is room for further improvement.

  The present invention improves the conventional stepping machine structure having only the effect of the above stepping exercise, trains the user to step on the foot, and naturally pulls the muscles on the back of both thighs, The purpose is to provide a treadle machine structure that fully stretches.

  An adjustable stepping machine according to the present invention is an adjustable stepping machine in which two pedals that can be moved up and down alternately are provided on one base, and the base is selectively front side or rear side. A set of legs that can be adjusted in altitude is provided at this point.

  According to the present invention, the one set of leg bodies is composed of two covering blocks pivotally supported on the base, the two covering blocks have substantially the same structure, and each flat covering is divided into two flat cuts. Correspondingly, there are few surfaces, and a shaft hole inclined to one of the flat cut surfaces is provided in the middle line of two corresponding flat cut surfaces. The individual lumps are also pivotally attached to the base by a method in which bolts are inserted through washers, gaskets and shaft holes, and the bolts can be rotated around the shaft.

  According to the present invention, the base has two lever bodies arranged at the front side and the rear side as main support structures, respectively, and the one set of leg bodies has shafts at both ends of one lever body. It is composed of two supported lumps, the structures of the two lumps are substantially the same, and each lump is provided with two flat cut surfaces corresponding to each other. One shaft hole inclined to one of the flat cut surfaces is provided in the middle line. Fixing pieces having a screw hole at the center are provided at both ends of the lever body, and the individual lump is a lever body by tightening the screw hole at the center of the fixing piece by inserting a bolt through a washer, a gasket and a shaft hole. The bolt can be pivoted about the shaft.

  According to the present invention, the two pedals are respectively connected to the hydraulic cylinder, and the two pedals are moved up and down relatively alternately by the damping action of the hydraulic cylinder, and the operation of the pedal is maintained in a coordinated manner.

  According to the present invention, the two pedals are respectively connected to the pneumatic cylinder, and the two pedals are moved up and down relatively alternately by the damping action of the pneumatic cylinder, and the operations of the pedals are maintained in cooperation. The two pedals are connected to the friction pieces, respectively, and the two pedals are moved up and down relatively alternately by the friction action of the friction pieces, and a blocking portion is formed at a place where the two pedals are in contact with the ankles on the rear side. The

  According to the present invention, the one set of leg bodies is composed of two covering blocks pivotally supported on the base, the two covering blocks have substantially the same structure, and each flat covering is divided into two flat cuts. There are two corresponding flat cutting planes, one of which is provided with a shaft hole inclined to the flat cutting plane, and the lump is provided with two different plane cutting planes. A flat pasting side is provided, and the distance between the two flat pasting sides and the shaft hole is smaller than the distance between the two flat cut surfaces and the shaft hole. An anti-sliding groove pattern is provided on a flat cut surface of the lump.

  Compared with the prior art, when the present invention is carried out, a set of legs adjustable on the front side or the rear side of the base of the stepping machine can be selected, and the user can select the base if necessary. When the user performs a stepping motion with a stepping machine, the body naturally tilts forward and maintains the balance of the center of gravity, As well as stretching the back muscles of both thighs, it is possible to simultaneously obtain the effects of training exercises of both stepping and muscle tensioning.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, and the entire operation method will be described.

  As shown in FIG. 1, the overall structure of a stepping machine according to the present invention is provided with two base pedals 10 that can be moved up and down alternately and relatively, and an operator steps on the pedal 20 with both feet. By using the structure, when the operator applies a force, the two pedals 20 are moved up and down relatively alternately, and there is an effect of exercise and training that can imitate the stepping walk for the operator.

  As shown in FIGS. 2 and 3, one set of legs 30 capable of adjusting the altitude is provided on the front side (or rear side) of the base 10. In this embodiment, the base 10 Two lever bodies 11 respectively arranged at the rear side are used as main support structures, and the front ends of the two pedals 20 are pivotally attached to the front lever body 11 of the base 10 and are respectively hydraulic cylinders 12 (or The two pedals 20 are moved up and down relatively alternately by the damping action of the hydraulic cylinder 12 and the operation of the pedals is maintained in a coordinated manner.

  The leg body 30 is composed of two covering blocks 31 (to increase the height) 31 pivotally attached to both ends of one lever body 11, and two covering blocks as shown in FIGS. The structure of 31 is substantially the same, and each flat lump 31 is provided with two flat cut surfaces 311 corresponding to a small number, and the flat cut surface 311 is provided with a fringing prevention groove pattern as a portion in contact with the ground. In addition, one shaft hole 312 is provided in the middle line of two corresponding flat cut surfaces 311, and the shaft hole 312 is inclined to one flat cut surface 311, and the two flat cut surfaces are provided on the litter 31. Two flat application sides 313 different from 311 are provided, and the distance between the two flat application sides 313 and the shaft hole 312 is smaller than the distance between the two flat cutting surfaces 311 and the shaft hole 312.

  When assembling the whole, first, the fixing piece 35 is assembled integrally with the lever body 11 and the bolt 32 is inserted into the washer 33, the gasket 34 and the shaft hole 312 to make the port 32 the center of the fixing piece 35. By tightening the screw holes 351, the lump 31 is pivotally supported at the end of the lever body 11, and the bolt 32 can be rotated about the axis.

  Therefore, the user can adjust the altitude of the leg 30 by rotating the lump 31 according to actual needs. As shown in FIG. The cut surface 311 may be rotated so as to be in a use state in contact with the ground. In this case, the overall height of the leg 30 is held in a state of a small inclination, and the user performs a muscle pulling exercise at a small angle. When the user rotates the lump 31 from the shaft hole 312 so that the long flat cut surface 311 is in contact with the ground, the overall height of the leg 30 is such that the base 10 is moved to the front side. This means that the body is tilted forward and the center of gravity is increased if the user performs a large stepping or muscle pulling exercise with a stepping machine. By maintaining equilibrium It is possible to extend the side of the muscle after both thigh. Furthermore, when the user rotates the lump 31 from the shaft hole 312 to a use state where the shortest flat pasting side 313 contacts the ground, as shown in FIG. Holds the base 10 in a state of approaching the horizontal state, so that the user can perform a normal stepping exercise and can obtain the effects of both stepping and muscle tension training.

  A blocking portion 21 is formed at a position in contact with the ankles on the rear side of the two pedals 20, and the blocking portion 21 is slightly higher than the plane of the pedal 20, and when the user adjusts the stepping machine to the form of muscle tension, As shown in FIG. 6, the blocking action of the blocking portion 21 can prevent both thighs from sliding down.

  Further, as shown in FIG. 8, the two pedals 20 are connected to the friction pieces 13, and the two pedals 20 are moved up and down relatively alternately by the friction action of the friction pieces 13, and the stepping action is performed. It can be maintained in coordination.
