Therefore, by adjusting the tilt angle of the lift frame relative to the up and down yaw of the base, the trajectory of the pedal can be changed to strengthen the leg muscles of different parts, and the lift frame and the slope adjusting device are The space configuration between the two can effectively achieve the purpose of simplifying the structure and reducing the manufacturing cost.
In the pedal hoisting mechanism provided by the present invention, the lifting frame has two sliding tubes, a fixing base, and a pivoting tube, the two sliding tubes are located on the left and right sides of the base, and the fixing seat is fixed to the The front end of the two sliding tubes is pivotally connected to the top end of the bracket, and the pivoting tube is connected to the rear end of the two sliding tubes and pivotally connected to the base at both ends thereof.
In the pedal hoisting mechanism provided by the present invention, the driving rod has a screw and a sleeve, and one end of the screw is connected to the driving source, and can be rotated by the driving source, and the sleeve is screwed to The screw is pivotally connected to the bracket, and is driven by the screw to be displaced along the axial direction of the screw to drive the bracket, thereby achieving the effect of changing the length of the driving rod.
In the pedal hoisting mechanism provided by the present invention, the bracket has a main rod body, an axle, and two rollers, and the main rod body is pivotally connected to the front end of the lifting frame and the rear end of the driving rod, and the axle connection At the bottom end of the main rod body, the two rollers are rotatably disposed at two ends of the axle shaft for abutting against the support surface to increase structural stability.
For a detailed description of the structure, features, and advantages of the present invention, a preferred embodiment is illustrated and described in conjunction with the following drawings.
Referring to the first drawing, in order to apply the elliptical machine 10 of a preferred embodiment of the present invention, the elliptical machine 10 shown in the drawing comprises a frame 12, a flywheel set 14, two pedal sets 16, and two grips 18, Since the elliptical machine 10 is a conventional technique, the structural relationship and the operation flow between the aforementioned elements will not be described herein. Referring to the second figure, the pedal lift mechanism 20 of the preferred embodiment of the present invention includes a base 30, a lift frame 40, and a pitch adjustment device 50.
The base 30 is mounted on a support surface G (such as the ground) for fixing the frame 12 of the elliptical machine 10.
The lift frame 40 has two sliding tubes 42, a fixing base 44, and a pivoting tube 46. The two sliding tubes 42 are located on the left and right sides of the base 30 for mounting the pedal group 16 thereon; the fixing base 44 is fixed at the front ends of the two sliding tubes 42 at two ends thereof; the pivoting tube 46 is connected to the two sliding tubes The L-shaped lug 32 of one of the bases 30 is pivotally connected to the rear end of the tube 42 and at both ends thereof. Thereby, the position of the lift frame 40 after installation is higher than that of the base 30, as shown in the fourth figure.
Referring to Figures 4 and 5, the tilt adjustment device 50 has a drive source 60, a drive rod 70, and a bracket 80, wherein the drive source 60 is fixed to the base 30 and between the front end of the lift frame 40. The driving rod 70 has a screw 72 and a sleeve 74. One end of the screw 72 is connected to the driving source 60, and can be rotated by the driving source 60. The sleeve 74 is screwed to the screw 72 and can be received by the screw 72. The screw 72 is driven to be displaced along the axial direction of the screw 72; the bracket 80 has a main rod body 82, an axle 84, and two rollers 86, wherein the top end of the main rod 82 is pivotally connected to the lift frame 40. At the front end of the sliding tube 42, the middle portion of the main rod body 82 is pivotally connected to the rear end of the sleeve 74 of the driving rod 70; the wheel shaft 84 is connected to the bottom end of the main rod body 82; the two rollers 86 are rotatably disposed on the two sides of the wheel shaft 84. The end is used to abut the support surface G to increase the stability of the structure.
When the user wants to change the movement track of the pedal set 16, the drive source 60 is first activated to drive the screw 72 of the drive rod 70 to rotate in place, and then the sleeve 74 of the drive rod 70 is driven by the screw 72 to push the support back. The frame 80 forces the bracket 80 to stably move backward by the sliding of the rollers 86 along the support surface G, and simultaneously pushes the lift frame 40 during the movement, so that the sliding tube 42 of the lift frame 40 is pivoted The axis of the nozzle 46 is pivoted upwardly to form a predetermined angle with the support surface G, as shown in FIGS. 5 and 6, so that the pedal group 16 rises with the sliding tube 42 of the lift frame 40. By changing the tilt angle, the pedal group 16 can be yawed back and forth along different motion trajectories when subjected to the user's pedaling force, so as to achieve the purpose of training the leg muscles of different parts.
In summary, the pedal hoisting mechanism 20 of the present invention designs the slope adjusting device 50 and the lift frame 40 in a front-rear manner, and can omit unnecessary components and is not easily limited by space to achieve a simplified structure. The assembly is convenient, and the manufacturing cost is reduced. In use, the pedal group 16 can also be adjusted to an appropriate tilt angle according to the user's needs, so as to train the muscles of a specific part.
