A pivotal axle 36 is pivotally connected and fixed onto the pivotal board 23 of the baseboard 21, and an end of the pivotal axle 36 has a quarterly circular eccentric protruding pillar 361 such that the quarterly circular protruding pillar 361 is embedded into an axle hole 352 of the transmission disc semicircular (as shown in FIG. 3A), and a poking rod 341 of the transmission disc driving module 34 is latched to a serrated groove 351 of the transmission disc 35, and another end of the pivotal axle 36 has an eccentric axle rod 362, such that the eccentric axle rod 362 can be extended correspondingly into the guide slot 16 of the guide pin base 15 of the link board 13.
An adjusting mechanism 40 pre-installs a program and a circuit for controlling and driving, and the adjusting mechanism 40 has a motor 41 installed at a side of the baseboard 21 and latched and connected by an axle rod 411 of the decelerating mechanism 412 and a horizontal screw rod 42, and another end of the horizontal screw rod 42 is pivotally connected to the pivotal board 24.
A back-and-forth slide and swing module 50 is pivotally connected by a plurality of board stands, and the first slide base 51 is comprised of front and rear frames 52 and a middle board module 53, and both left and right sides of the front and rear frames 52 separately have a rail 521. The first slide base 51 is pivotally connected to the rails 521 on the front and rear frames 52 through two corresponding pivotal bases 22 of the left-and-right swing module baseboard 21 for pivotally installing the first slide base 51 on the left-and-right swing module 20, and embedding two sideboards 531 of the middle board 53 into the latch grooves 541 on both sides of a driving member 54, and sheathing the driving member 54 on a screw rod 42 of an adjusting mechanism 40. The top of the first slide base 51 is connected to a pivotal connecting point 562 of a second slide base 55 through a board stand, and the second slide base 55 is comprised of a slide and swing rail stand 56, and both left and right sides of the slide and swing rail stand 56 also have a rail 561 separately. A swing stand 57 is a rectangular frame having a support board 571 extended from the bottom of the periphery of the swing stand 57 for pivotally connecting each support board 571 to the second slide base 55 and each rail 561 of the slide and swing rail stand 56. A driving member 37 is pivotally connected to a pivotal connecting position 572 on the right side proximate to two support boards 571 of the driving mechanism 30, and the driving member 37 is a rectangular member with an end having an axial hole 371 pivotally connected to the support board 571 and a pivotal connecting position 572 of the slide base rail 561, and another end having a pivotal hole 372 for passing and fixing the transmission shaft 33.
Referring-to FIG. 4A for a side view of the original status of a training apparatus A of the present invention, if the motor 31 of the driving mechanism 30 is driven by the decelerating mechanism 32 to rotate the transmission shaft 33 clockwise, the driving member 37 is rotated to drive the second slide base 55 and the swing stand 57 to slide back and forth and swing up and down. If the transmission shaft 33 drives the driving member 37 to deflect to the position of Point a (as shown in FIG. 4B), then the second slide base 55 and the swing stand 57 will slide and swing to a titled position with the front side lower than the rear side. If the driving member 37 is deflected to the position of Point b (as shown in FIG. 4C), the second slide base 55 and the swing stand 57 will slide and swing back to its horizontal position. The driving member 37 continues to deflect to the position of Point c (as shown in FIG. 4D), the second slide base 55 and the swing stand 57 will slide and swing to a tilted position with the front side higher than the rear side. If the driving member 37 continues its rotation and returns to the position of the original point o (as shown in FIG. 4A), then the second slide base 55 and the swing stand 57 will slide and swing back to their original positions at the same time. With the aforementioned slide and swing movements, the second slide base 55 and the swing stand 57 simultaneously produce slide and swing movements with respect to the base module 10.
Referring to FIGS. 5A˜5C for schematic views of left and right tilted movements of a training apparatus A, the motor 31 is driven by the decelerating mechanism 32 to rotate the transmission shaft 33 and the transmission disc driving module 34, and the transmission disc 35 is driven to rotate. Since the number of poking rods 341 of the transmission disc driving module and the number of serrated groove 351 of the transmission disc are installed in the ratio of 1:2, therefore the transmission disc 35 will turn one round when the transmission disc driving module 34 turns two rounds (or the motor 31 is driven by the decelerating mechanism 32 to rotate the transmission shaft 33 for two rounds), such that the eccentric protruding pillar 361 pivotally connected to the semicircular axle hole 352 of the transmission disc 35 will drive the axle rod 362 of the pivotal axle 36 to rotate in the transversal guide slot 16 of the guide pin base 15, so as to drive the guide pin base 15 to turn pivotally, and the baseboard 21 is pulled and the pivotal connecting point of the connecting board 12 of the base module 10 is used as a center to produce left and right tilted swings.
Referring to FIGS. 6A˜6D for top views of a training apparatus of the present invention, if the transmission shaft 33 turns one round clockwise, the swing stand 57 will slide and swing towards the left corner of the original position with respect to the pivotal connection of the left-and-right swing module 20 (not shown in the figure) and the base module 10, and then the swing stand 57 will slide and swing back to the original position. If the transmission shaft 33 turns another round clockwise, the swing stand 57 will slide and swing towards the right corner with respect to the left-and-right swing module 20 and the base module 10, and then will slide and swing to the original position. If the motor 31 is driven by the decelerating mechanism 32 to turn the transmission shaft 33 counterclockwise, the transmission disc 35 will turn 90 degrees counterclockwise, such that the quarterly circular eccentric protruding pillar 361 of the transmission shaft 33 can be embedded and latched into another side of the semicircular axle hole 352 of the transmission disc 35 (as shown in FIG. 3B), and the wall of the semicircular axle hole 352 of the transmission disc 35 is pressed to rotate the eccentric protruding pillar 361. If the transmission shaft 33 turns one round clockwise, the swing stand 57 will slide and swing to the original position towards the left rear corner of the pivotal connection of the left-and-right swing module 20 and the base module 10, and then will slide and swing back to the original position (as shown in FIG. 6). If the transmission shaft 33 turns one round counterclockwise, the swing stand 57 will slide and swing towards the right rear corner with respect to the left-and-right swing module 20 and the base module 10, and finally will swing and slide back to the original position (as shown in FIG. 6D), so as to form a multidirectional balance training apparatus A for slide and swing exercises. Referring to FIGS. 7A and 7B for schematic views of movements of a balance training apparatus for slide and swing exercises in accordance with the present invention, and FIG. 8 for a flow chart of movements of a balance training apparatus for slide and swing exercises in accordance with the present invention, the method comprises the following steps:
(a) using an exercise apparatus A driven by a driving mechanism 30 installed on the exercise apparatus A for training a human body;
(b) pre-installing a program and a circuit in the exercise apparatus A, such that the motor 31 of the driving mechanism 30 drives the transmission shaft 33 to rotate counterclockwise, while driving a second slide base 55 and a swing stand 57 of a back-and-forth slide and swing module 50 to swing back and forth or up and down with respect to a base module 10; or working together with an adjusting mechanism to adjust the back-and-forth slide and swing module 50 to displace horizontally on the baseboard of the base module to change the swinging amplitude of the back-and-forth slide and the swing module;
(c) setting the driving mechanism 30 to simultaneously rotate the transmission disc driving module 34 and drive the transmission disc 35 and its pivotally connected eccentric protruding pillar 361 to link the guide pin base 15, and also pull a baseboard 21 of the left-and-right swing module 20 and use the pivotal connecting point of the base module 10 as a center to produce left, right and tilted swings; so as to form a multidirectional balance training apparatus A for slide and swing exercises.
Referring to FIGS. 9A and 9B, the driving member 54 is fixed onto a middle board module 53 of the first slide base 51, such that the driving member 54 can be operated by the motor 41 of the adjusting mechanism 40 and driven by the decelerating mechanism 412 to rotate the screw rod 42, and the driving member 54 can be displaced back and forth on the screw rod 42 to displace the first and second slide bases 51, 55 with respect to the baseboard 21. Since the swing stand 57 is pivotally connected to the driving mechanism 30, therefore the swing stand 57 will not be driven by the driving member 54 to displace. Referring to FIGS. 10A and 10B, it is known from the principle of lever that if a fulcrum is situated at the center, both front and rear ends of the rod are maintained in equilibrium; if the first and second slide bases 51, 55 are shifted to an appropriate distance to the rear or the position of the pivotal connecting point 562 (which is the fulcrum) is shifted to a position 562′ that approaches the pivotal connecting position 572 of the driving mechanism 30 and the swing stand 57, the rear rod section at the fulcrum 562′ of the second slide base 55 will become longer, and the front rod section at the fulcrum 562′ of the second slide base 55 will become shorter. If the driving mechanism 30 drives the front shorter rod section to swing to a swing distance d1 at a swing angle α1, the longer rear rod section will pivotally turn and swing with an angle β1 to produce a larger swing distance d2. On the other hand, if the first and second slide bases 51, 55 are adjusted to displace to an appropriate distance backward, the front rod section at the fulcrum 562′ of the second slide base 55 will become longer and the rear rod section will become shorter. If the driving mechanism 30 drives the long rod section to swing with an angle α2, the swing distance is equal to d1, and the swing angle of the short rod section will pivotally turn or rotate with a small angle β2 only, so as to decrease the amplitude, and the deflected distance is equal to d3 to define an adjusting mechanism 40 capable of adjusting the swing amplitude.
Referring to FIG. 11 for a first preferred embodiment of the present invention, an external casing base 60 is disposed on the exercise apparatus A, and a saddle seat 61 is formed on the external casing base 60 and provided for a user to ride and used for simulating horseback riding. Referring to FIG. 12 for a second preferred embodiment of the present invention, the exercise apparatus A installs an external casing base 62, and a platform 63 formed on the external casing base 62 for a user to stand on the platform 63 for conducting a balance training and simulating slides and swings in different directions, so as to enhance the function, effect and fun of the exercise.
Referring to FIG. 13 for a third preferred embodiment of the present invention, the driving mechanism 30 has a rectangular board 373 disposed on the backside of a pivotal hole 372 of a driving member 37 at an end without the transmission disc driving module 34, such that the corner can precisely cover the position of ¼ of a circle of the pivotal hole 372, and the transmission shaft 33 has an eccentric protruding pillar 331 with ¼ of a circle-protruded from an end corresponding to the pivotal hole 372 of the driving member for embedding the eccentric protruding pillar 331 of the transmission shaft 33 into the pivotal hole 372, so that the lateral plane 3311 of the eccentric protruding pillar 331 is aligned evenly with the lateral side 3731 at the corner of the board member 373 into a plane (as shown in FIG. 14A), and the top of the back-and-forth slide and swing module 50 has two parallel swing stands 58, 58′. Referring to FIGS. 15A and 15B, poking rods 341 of the transmission disc driving module and serrated grooves 351 of the transmission disc are installed with the ratio of 1:2, such that if the transmission disc driving module 34 turns two rounds, the transmission disc 35 will turn exactly one round. The driving mechanism 30 is operated, so that the swing stands 58, 58′ can produce back-and-forth slides and up-and-down and left-and-right titled swings. If the transmission shaft 33 rotates one round clockwise, the two swing stands 58, 58′ will be parallel and swing and slide towards the front left corner with respect to the baseboard 21 (not shown in the figure) and the base module 10, and then return to the original positions. If the transmission shaft 33 further rotates one round clockwise, the swing stands 58, 58′ will be parallel and swing and slide towards the front right corner with respect to the baseboard 21 and the base module 10 and then return to the original position. Referring to FIG. 14B, if the transmission shaft 33 rotates counterclockwise, the eccentric protruding pillar 331 of the transmission shaft 33 will rotate 180 degrees along a pivotal hole of the driving member 37, and then the lateral plane 3311 of the eccentric protruding pillar 331 will press precisely on a plane 3731 at a corner of the rectangular member 373 to pivotally turn the driving member to 180 degrees by the transmission shaft 33 (as shown in FIG. 14C) and displace the swing stand 58′ accordingly and parallelly with the front and rear of another swing stand 58. If the transmission shaft 33 rotates a round counterclockwise and operates together with the driving mechanism 3 as shown in FIGS. 15C and 15D, the swing stand 58 will slide and swing to the right rear corner and the swing stand 58′ will slide and swing to the right front corner, and the two swing stands 58, 58′ will be alternately intersected, and then returned to their original position. If the transmission shaft 33 further rotates one round clockwise, the swing stand 58 will slide and swing towards the rear left corner and the swing stand 58′ will slide and swing towards the front left corner and then the two swing stands 58, 58′ will be alternately intersected, and then returned to their original positions.
Referring to FIGS. 16A and 16B for front views of movements of two swing stands 58, 58′ intersected with each other, and FIG. 17 for a schematic view of a slide and swing exercise apparatus having two swing stands 58, 58′ in accordance with the present invention, the apparatus is applied as a snow skiing balance training apparatus B for performing a snow skiing and balance training with fun.
The transmission disc driving module 34 and the transmission disc 35 could be a gear mechanism, a belt pulley mechanism or other driving mechanism.
