Description

Technical Field

[0001] The exercise and fitness mechanism described in the present invention designs a riding toy for children. Background Art

[0002] Currently, there are many existing patents for riding mechanisms, including 200610069830.5, 95234111.5, 02253792.9, and Japanese Patent 10-309379, etc. These patents or other similar patents all have the following defects in structure or driving methods:

[0003] 1. Most existing products use a seat or gravity to press down, forcing the front and rear legs to open, and then through the movement of the body's center of gravity, the gravity acts on the pedals, and the pedals are stepped back to the original position, and then move forward through a one-way wheel. Such a design structure is very complex, which will result in a high manufacturing cost.

[0004] 2. Since there is a seat moving up and down on the back, first of all, there is a lack in bionic design, and furthermore, the rider's movements are not elegant.

[0005] 3. Some designs without seats achieve the purpose of striding and resetting the riding toy by stepping on and off the pedals on the abdomen to shift the center of gravity, which is very difficult to operate.

[0006] 4. In view of the problems existing in the field of the above-mentioned riding toys, the purpose of the present invention is to research and design a brand-new riding and fitness mechanism that combines entertainment and fitness, so as to replace and eliminate similar products with cumbersome designs and high manufacturing costs in this field. Therefore, it is very necessary to overcome the problems existing in the prior art. Summary of the Invention

[0007] In view of the problems existing in the field of the above-mentioned riding toys, the purpose of the present invention is to research and design a brand-new riding and fitness mechanism that combines entertainment and fitness, so as to solve the problems existing in the prior art:

[0008] 1. Complex structure and high manufacturing cost.

[0009] 2. Due to the driving method, the riding operation structure is complex and laborious.

[0010] 3. The bionic design is not beautiful and the rider's posture is not elegant.

[0011] 4. It cannot achieve better fitness exercise and entertainment effects.

[0012] The technical solution of the present invention is realized as follows:

[0013] The cycling fitness mechanism described in the present invention is characterized by comprising: a front body bracket, a handle, a lever arm, a front leg bracket, pedals, a one-way front wheel assembly, a body frame, an intermediate connecting rod, a rear body bracket, rear leg brackets, a one-way rear wheel assembly, a tray, a spring, and a pull rod. A handle is installed on the upper part of the front body bracket of the mechanism, a lever arm is fixedly installed in the middle of the front body bracket, a front leg bracket is installed on the lower part of the front body bracket, pedals are fixedly installed on the front leg bracket, and a one-way front wheel assembly is installed at the bottom end of the front leg bracket; the front end of the body frame is hinged to the middle of the front body bracket of the mechanism, and the rear end of the body frame is hinged to the middle of the rear body bracket of the mechanism; the front end of the intermediate connecting rod is hinged to the end point of the lever arm of the front body bracket, and the rear end of the intermediate connecting rod is hinged to the upper end of the rear body bracket; rear leg brackets are installed on the lower part of the rear body bracket, and a one-way rear wheel assembly is installed at the bottom end of the rear leg brackets; the tray is hinged to the body frame, the spring is fixed above the tray, there is a hole in the middle of the tray, and the bottom end of the pull rod is hinged to the end point of the lever arm of the front body bracket and the front end of the intermediate connecting rod at the same point. The pull rod passes through the hole in the tray and passes through the spring to lock the upper end of the spring. The pull rod applies force to the spring as the lever arm moves.

[0014] There are two front leg brackets described in the present invention. Two pedals are symmetrically and fixedly installed on the front leg brackets, and there are two sets of one-way front wheel assemblies at the lower ends of the front leg brackets.

[0015] There are two rear leg brackets described in the present invention. Two sets of one-way rear wheel assemblies are fixedly installed at the lower ends.

[0016] The one-way front wheel assembly and the one-way rear wheel assembly described in the present invention are composed of a wheel frame and a wheel. The wheel can only move forward and cannot move backward; the wheel is fixedly installed inside the wheel using a one-way bearing to achieve one-way rotation, or it can also achieve one-way rotation through the eccentric wheel principle using a circlip.

[0017] The bottom end of the pull rod described in the present invention is hinged to the front end of the lever arm and the front end of the intermediate connecting rod at the same point. The pull rod passes through the hole in the middle of the tray and also passes through the spring to lock the upper end of the spring. When the lever arm moves downward, it drives the pull rod to apply force to the spring.

[0018] The body frame described in the present invention is hinged to the middle of the rear body bracket of the mechanism, and the rear end of the intermediate connecting rod is hinged to the upper end of the rear body bracket. In this way, the front body bracket and the rear body bracket directly form a symmetric linkage. When the front leg bracket of the front body frame steps forward, through the force applied by the intermediate connecting rod, the rear body bracket rotates around the hinge point with the body frame, and the rear leg brackets move backward.

[0019] When using the present invention:

[0020] 1. The user holds the handle and steps on the pedals as if riding on a horse.

[0021] 2. The first movement during cycling is to pull the handle, just like pulling a horse's reins, while pedaling the pedals. The front body bracket of the mechanism will rotate around the hinge point hinged to the body frame, which means the handle moves closer to the cyclist, and the single forward wheel at the lower end of the front leg bracket rotates forward; at the same time, the end point of the lever arm in the middle of the front body bracket will also rotate downward around this hinge point, driving the pull rod to move downward. The pull rod will continuously apply force to the spring. When reaching the critical point of the maximum spring elasticity, the cyclist can clearly feel the resistance brought by the spring. At this time, the single forward wheel at the lower end of the front leg bracket has advanced one step forward; since the front end point of the lever arm is hinged to the front end of the intermediate connecting rod, the intermediate connecting rod will be pulled by the lever arm. The rear end of the intermediate connecting rod is hinged to the upper end of the rear body bracket, and the upper end of the rear body bracket will also be forced to move forward at the same time. The middle part of the rear body bracket is hinged to the body frame. In this way, the upper and lower ends of the rear body bracket will rotate around this hinge point, and the single rear wheel at the bottom end of the rear leg bracket will move backward. However, the characteristic of the one-way wheel is that it cannot move backward, so it can only stay in place.

[0022] 3. When the cyclist feels the maximum resistance of the spring, use this rebound force to push the handle forward. At this time, the single forward wheel at the lower end of the front leg bracket will rotate in the opposite direction around the hinge point between the body frame and the front body bracket. And the characteristic of the one-way wheel is that it cannot move backward, so the front leg bracket will stay in place together with the single forward wheel; since the handle moves forward, the lever arm will move backward instead. The lever arm will transmit the thrust to the intermediate connecting rod through the hinge point, and the intermediate connecting rod will also conduct the thrust to the upper end of the rear body bracket, causing the upper end of the rear body bracket to move backward. Since the middle part of the rear body bracket is hinged to the body frame, the rear body bracket will rotate around the hinge point, and the single rear wheel at the lower end of the rear leg bracket will move forward around this hinge point. In this way, when the front leg bracket takes a step forward and stops, the rear leg bracket also takes a step forward accordingly.

[0023] 4. Repeat these two movements during cycling, and the present invention will keep moving forward.

[0024] The advantages of the present invention are obvious and mainly manifested in:

[0025] 1. The present invention truly achieves balancing the human body gravity and the spring force skillfully with the simplest connecting rod structure, realizing the functions of such products.

[0026] 2. The structure of the present invention is very simple and the manufacturing cost is extremely low.

[0027] 3. The cycling operation is very in line with the real horse-riding posture, with extremely high vividness.

[0028] The present invention has the characteristics of novel structure, reasonable design, simple processing, low manufacturing cost, etc. It is suitable for various occasions for exercise and has strong entertainment. Batch input into the market will surely produce positive social benefits and significant economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS
