Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a skate fitness car, in particular to an improved skate fitness car operated by a user's legs to bring left and right support rods inwardly together or separate the left and right support rods outwardly from each other, or applying forces by both legs to the left and right support rods alternately, or twisting the user's body for sliding the skate fitness car to move forward smoothly, so as to give more fun and more diversified recreational effects of the skate fitness car.
  • 2. Description of the Related Art
  • In a triangular design of a skate fitness car driven by bringing the left and right support rods inwardly together and separating the left and right support rods outwardly from each other alternately, the car body can be slid and moved forward. In FIGS. 1 to 3, a front end of left and right carrier rods 10 is pivotally coupled to a car frame 1 through a pivotal pipe 101, such that the left and right carrier rods 10 can be brought together or separated from each other, and a vertical pipe 20 is pivotally coupled to a front end of the car frame 1, and a handlebar 21 and a front compacting wheel 23 are installed at the top and bottom of the car frame 1 respectively. In addition, a carrier 12 is installed separately to two carrier rods 10, and a rear driving wheel module 30 is installed at a rear end of each carrier rod 10, wherein the rear driving wheel module 30 includes a rear fork 301 for installing a rear driving wheel 302, and an upper end of the rear fork 301 is vertically and pivotally coupled to a rear end of the carrier rod 10 through a pivotal pipe 3011, and the bottom of the rear fork 301 is dragged by a resilient element 303 at the carrier rod 10 through an extended board 3012, such that the rear fork 301 and the rear driving wheel 302 have the resilience force for restoring their positions anytime. When use, a user peddles the carriers 12 with movements of bringing both legs together and separating both legs, such that the two carrier rods 10 can be moved towards each other and away from each other alternately, and the two rear driving wheel modules 30 are swayed accordingly, and the rear driving wheels 302 can be moved forward in an S-shaped path, so as to achieve the effects of driving the car body to move forward and providing a fitness exercise for both legs. When a user operates the carriers 12 to move towards and away from each other by both legs (as shown in FIGS. 2 and 3), the pivotal pipe 3011 pivotally coupled to the rear fork 301 is installed in a perpendicular direction, and thus the position restoring movement cannot be achieved. To make the rear driving wheel module 30 to sway accordingly, a resilient element 303 is provided for a compulsory position restoring movement.
  • Undeniably, the aforementioned skate fitness car can provide users the expected fitness exercise effect when the user is operating and driving the car body to slide forward, but the conventional skate car still has the following drawbacks after a long time of use:
  • 1. Since the left and right support rods are moved towards and away from each other by both legs continuously, therefore both legs will get tired quickly, and such operation is a single operation mode which is suitable for young people but not for children and elderly people, and the target users are limited.
  • 2. In view of the description above, the way of driving the car body to slide totally relies on bringing together and separating the left and right support rods continuously by both legs, which is a single operating mode, and the exercise becomes monotonous and boring soon, and thus users may lose their interest of continuing the exercise.
  • 3. Since the resilient element has a resilience force for restoring the position of the rear driving wheel modules, the resistance of driving the rear driving wheels becomes greater and affects the speed and smoothness of the sliding car body.
  • SUMMARY OF THE INVENTION
  • In view of the shortcomings of the prior art, the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally developed an improved skate fitness car having a rear driving wheel module separately installed to the left and right support rods and pivotally coupled to a vertical pipe, and a link rod pivotally coupled to a rear end of the left and right support rods and disposed between the left and right support rods for automatic swaying and position restoration, such that when the link rod is released, a user can bring together or separate the left and right support rods by both legs, and the left and right rear driving wheels can be rolled forward in an S-shaped path in compliance with a front compacting wheel at the bottom of the vertical pipe to drive the car body to slide, or when the link rod is locked, the user can apply forces to the left and right support rods by both legs or twist the body, such that the left and right rear driving wheels can be rolled forward in an S-shaped path in compliance with the front compacting wheel to drive the car body to slide. In the multiple operating modes, the effects of extending the scope of target users, increasing the range of fitness exercise and enhancing the fin and recreation of the skate fitness car can be achieved. The present invention can also achieve the expected exercise fitness purposes and effects.
  • Another objective of the present invention is to provide an improved skate fitness car, wherein the left and right rear driving wheels are swayed and restored by applying forces through the user's legs or twisting the user's body. With the installation of the front compacting wheel, the speed and smoothness of sliding the car body can be enhanced.
  • A further objective of the present invention is to provide an improved skate fitness car, wherein a pivot and a lock element are installed at a front end proximate to the left and right support rods, such that the vertical pipe can be spread open or folded to achieve the effects of providing a convenient use and saving storage space.
