The two sliding grooves with a predetermined length have respective axial rods at the outer middle sides thereof. Thereby, the sliding grooves are adjustable along the support frames to adjust tilting angles at the two sides; and thus, elliptical tracks of the pedals are changed to present operations of moving upwards, downwards and flatly.

Description

    FIELD OF THE INVENTION
  • The present invention relates to exercising training machine, and particularly to a treading exercising machine with adjustable elliptical track for tilting at two sides [0001]
  • BACKGROUND OF THE INVENTION
  • A prior art, U.S. Pat. No. 6,146,313 disclosed a cross training exercise device. In that, an exercise device to simulate various types of stepping motions is disclosed. The device comprises a frame having a pivot axis defined thereon, the frame configured to be supported on a floor; a first and second foot link. Each foot link including a first end and a second end; a foot support for receiving the user's feet. The foot support is supported by the first and second foot links, and the foot support having a heel supporting section and toe supporting section. A coupling system is associated with the first end of each foot link for coupling the first end of each foot link to the pivot axis so that the first end of each foot link travels in a closed path relative to the pivot axis. A guide associated with the frame and operative to engage and direct the second ends of the foot links along preselected reciprocating paths of travel as the first ends of the respective foot links travel along their paths of travel, so that when the exercise device is in use and when the second end of one of the foot links travels forwardly from a rearmost position, the heel supporting section of the foot support rising relative to the toe supporting section of the foot support so that the heel portion of the user's foot initially rises at a faster rate than a toe portion thereof and when the second end of the foot link travels rearwardly from a foremost position, the heel supporting section of the foot support lowering relative to the toe supporting, section of the foot support so that the heel portion of the user's foot initially lowers at a faster rate than the toe portion. An elevation system serves for selectively and automatically changing at least one of the elevation and angular orientation of the guide relative to the frame so as to alter the path traveled by the second ends of the first and second links, and to alter the nominal relative orientation of the heel supporting section of the foot support relative to the toe supporting section of the foot support. [0002]
  • However, in this prior art, the traveling paths of the foot supports can not be changed greatly. Even the guide is adjusted to a largest tilt angle and a smallest tilt angle. However, a line by connecting the respective highest supporting point with the respective lowest supporting point is only slightly shifted from the original line with an angle of 10 to 45 degrees. Thereby, the elliptical paths by changing the foot supports only changes slightly. The paths simulated are only finite. Only a flat path or a slightly upward path can be simulated. Thereby, the prior art design has only finite functions which is not satisfied by the users. [0003]
  • SUMMARY OF THE INVENTION
  • Accordingly, the primary object of the present invention is to provide a treading exercising machine with adjustable elliptical track to tilt at two sides thereof. The treading exercise machine has a base. One end of the base having two sides; each side having a respective support frame. [0004]
  • In that, the support frames are pivotally installed with symmetrical sliding grooves. Two sides of another end of the base have respective coaxial cranks. Each crank is pivotally connected to one end of a pedal. Another ends of the two pedals are connected to sliding wheels. The sliding wheels are received in the sliding groove so as to move therein. The two sliding grooves with a predetermined length have respective axial rods at the outer middle sides thereof so that the sliding grooves are pivotally installed to the support frames. [0005]
  • Thereby, the sliding grooves are adjustable along the support frames to adjust tilting angles at the two sides; thus, elliptical tracks of the pedals are changed to present operations of moving upwards, downwards and flatly. [0006]
  • The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing. [0007]
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a schematic view showing the structure of the present invention. [0008]
  • FIG. 2 is an assembled plane view showing the structure of the present invention. [0009]
  • FIG. 3 is a schematic view showing another orientation of FIG. 2. [0010]
  • FIG. 4 is an exploded schematic view of the adjuster according to the present invention.[0011]
  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • Referring to FIGS. [0012] 1 to 3, the treading exercising machine with adjustable elliptical track to tilt at two sides thereof the present invention. The machine has a base 10. One end of the base 10 has two sides. Each side has a respective support frame 11. The support frames 11 are pivotally installed with symmetrical sliding grooves 20. Another end of the base 10 have a coaxial left and a coaxial right cranks 12. The left and right cranks 12 are pivotally connected to one end of a left and a right pedals 30. Another ends of the two pedals 30 are connected to sliding wheels 31. The sliding wheels 31 can be received in the sliding grooves 20 so as to move therein. The two sliding grooves 20 with a predetermined length have respective axial rod 21 at the outer middle sides thereof so that the sliding grooves 20 can be pivotally installed to the support frames 11. Thereby, the sliding grooves 20 are adjustable along the support frames 11 to adjust leftward and rightward tilt angles (referring to FIG. 4). Thus, the elliptical tracks of the pedals 30 are changed to present the operation of moving upwards, downwards and flatly. An angle adjuster is installed between bottoms of the sliding grooves 20 and the base 10 so that the oblique angle of the sliding groove 20 is changeable and can be positioned after adjustment.
  • The angle adjuster [0013] 40 includes an H type frame 41 pivotally installed to the bottoms of the two symmetrical sliding grooves 20. A bottom of the H type frame 41 is pivotal with a push rod 42. Two sides of the push rod 42 have guide holes 421 for being firmly secured to the two guide rods 13 of the base 10. A screw hole 422 is formed at a middle rod of the H type frame. Two opposite inner sides of the support frames 11 are formed with symmetrical guide rods 13. A lifting motor 50 is installed at a predetermined position of the base 10. The screw rod 51 of the lifting motor 50 is screwed into the screw hole 422 of the push rod 42.
  • By above structure, when the lifting motor is actuated, the screw rod [0014] 51 will drive the push rod 42 to move forwards and backwards so as to drive the H type frame 41 pivotally installed to the push rod 42 to move synchronously. Thereby, the oblique angle of the sliding grooves 20 at the upper end of the H type frame 41 is changed leftwards or rightwards. Thus, when the left and right pedals 30 of the two sliding grooves 20 are operated, a different elliptical track is generated. If the sliding groove 20 is adjusted to tilt rightwards (referring to FIG. 2), when the left and right pedals 30 move, an elliptical track for simulating a downward move is generated. If the sliding grooves 20 moves leftwards (referring to FIG. 3), when the left and right pedals 30 move, an elliptical track for simulating an upward move is generated. When the sliding grooves 20 are adjusted to be in horizontal condition, an elliptical track as to move flatly is generated.
  • The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims. [0015]
