Description

Technical Field

[0001] This invention relates to a training device, and more particularly to a safe basic cycling skills trainer. Background Technology

[0002] Currently, the bicycle industry lacks specialized training equipment for skill riding; conventional training utilizes full-size stunt bikes.

[0003] 1) The entire stunt car is heavy.

[0004] 2) Training requires constant cycling, which consumes physical strength and has low training effectiveness.

[0005] 3) Specific training venues are required.

[0006] 4) The probability of crashing increases when training skills and movements.

[0007] Existing methods of using a full-size bicycle for skill training are problematic. The weight of the bicycle, combined with the act of riding, places a significant strain on the trainee's physical strength, increasing the likelihood of falls and injuries. Furthermore, it requires a specific training area, increasing limitations and reducing training efficiency. Summary of the Invention

[0008] To overcome the above shortcomings, the present invention provides a basic cycling skills trainer that has low requirements for training venues, basically avoids injuries to trainees during training, provides necessary safety guarantees, eliminates the limitation of training venues, and improves training efficiency.

The seat tube is inserted into the vertical tube. An elastic slit is formed on the upper side wall of the vertical tube, and a clamp is fitted on the outer circumference of the vertical tube. The clamp can press the outer circumference of the vertical tube to make the vertical tube clamp the seat tube.

[0011] As a further improvement of the present invention, at least one set of foot pedal bushings are fixedly provided at intervals on the left and right side walls of the frame body, and a connecting shaft is provided on the foot pedal, which is axially stopped and inserted into the foot pedal bushing.

[0012] As a further improvement of the present invention, three foot pedal bushings are fixedly provided at intervals on the frame body. The three foot pedal bushings are a first foot pedal bushing and a second foot pedal bushing symmetrically located on the front and rear sides of the seat, and a third foot pedal bushing adjacent to the seat.

[0013] As a further improvement of the present invention, a balance wheel bushing is fixedly installed at the rear end of the frame body, the balance wheel bushing and the frame body form a T-shaped structure, and the shafts of the two balance wheels are fixedly inserted into the two ends of the balance wheel bushing.

[0014] As a further improvement of the present invention, a safety support rod is also fixedly provided at the rear end of the frame. The safety support rod extends perpendicularly to the axis of the balance wheel and extends a certain distance beyond the outer surface of the two balance wheels. The end of the safety support rod facing away from the frame body can contact the ground when a set tilt angle is set.

[0015] As a further improvement of the present invention, a safety support sleeve is fixedly provided on the inner side of the rear end of the vehicle frame, and a safety support rod is inserted into the safety support sleeve. At least one threaded hole is provided on the outer circumferential wall of the safety support sleeve, and a fastening screw is movably screwed into the threaded hole.

[0026] Example: A basic cycling skills trainer includes a frame body 2, a shock-absorbing fork 7, a handlebar assembly 15, pedals 9, a seat 14, and balance wheels 13. With the actual usage direction as the reference, a head tube 1 is fixedly installed at the front end of the frame body 2. The upper end of the shock-absorbing fork 7 is axially stopped and rotatable in the circumferential direction, inserted into the head tube 1. An elastic element 10 made of elastic material is fixedly installed at the lower end of the shock-absorbing fork 7. The pivot of the handlebar assembly 15 is coaxially fixedly connected to the upper end of the shock-absorbing fork 7. The seat 14 is fixedly installed on the middle part of the frame body 2. At least two balance wheels 13 are rotatable and installed on the left and right sides of the rear end of the frame body 2. At least two pedals 9 are axially stopped and installed on the left and right sides of the middle and rear part of the frame body 2. This cycling skills trainer is used for training techniques such as lifting the bike and jumping while cycling. During training, the trainee sits on the seat 14 or stands on the pedals 9, grasps the left and right handlebars on the handlebar assembly 15 with both hands, and selects two pedals 9 to pedal as needed. The trainee lifts the left and right handlebars on the handlebar assembly 15, causing the entire frame to tilt around the balance wheel 13. When the front of the frame is suspended in the air for a certain period of time and then falls back to its original position, the elastic element 10 at the lower end of the shock-absorbing fork 7 contacts the ground, which plays a buffering role and prevents hard contact, thus protecting the trainee from injury due to the impact. The above actions simulate the special riding state during cycling. After the trainee becomes proficient on the trainer, they can then use a bicycle for skill training, which can effectively reduce the probability of falling and prevent the trainee from getting injured. The frame body 2 can be integrally formed or welded from tubing. The frame body 2 is best composed of a tilted front section and a horizontal rear section, which is similar to a bicycle frame and has high strength, making it less prone to deformation during training.

[0027] A riser tube 3 is fixedly installed in the middle of the frame body 2, and a seat tube 14 is fixedly installed on the seat 14. The seat tube 14 is inserted into the riser tube 3. An elastic slot is formed on the upper side wall of the riser tube 3, and a clamp is fitted around the outer circumference of the riser tube 3. The clamp can press the outer circumference of the riser tube 3 to clamp the seat tube 14. This structure allows for adjustment of the seat 14 height as needed. Ideally, an eccentric handle is provided on the clamp, which can be rotated to tighten or loosen the clamp for easy adjustment.

[0028] At least one set of foot pedal sleeves 4 are fixedly provided at intervals on the left and right side walls of the frame body 2. The foot pedal 9 is provided with a connecting shaft, and the connecting shaft on the foot pedal 9 is axially stopped and inserted into the foot pedal sleeve 4. The pedal axle sleeve 4 is preferably in sets of 2 to 4, but can also be in sets of 1 or more. The above structure is used to assemble the pedal 9. Multiple sets of pedal axle sleeves 4 are used to adjust the distance between the pedal 9 and the seat, which can meet the needs of trainees of different heights. During training, different trainees can adjust the pedal distance according to their own habits and choose different positions of the pedal 9 to simulate the position of the pedal 9 in actual conditions. The pedal axle sleeve 4 has an internal thread structure on its inner side, and the connecting shaft on the pedal 9 has an external thread structure. The connecting shaft on the pedal 9 is threadedly connected to the internal thread structure of the pedal axle sleeve 4. This structure can realize the quick installation and removal of the pedal 9 and can adjust the angle of the pedal 9 to realize riding simulation. The connecting shaft of the pedal 9 can also be fixedly inserted into the pedal axle sleeve 4, or the pedal axle sleeve 4 can be extended directly to form the pedal 9.

[0029] Three foot pedal sleeves 4 are fixedly installed at intervals on the frame body 2. The three foot pedal sleeves 4 are the first foot pedal sleeve 4 and the second foot pedal sleeve 4, which are symmetrically located on the front and rear sides of the seat 14, and the third foot pedal sleeve 4, which is close to the seat 14.

[0030] A balance wheel bushing 5 is fixedly installed at the rear end of the frame body 2, forming a T-shaped structure with the frame body 2. The axles of two balance wheels 13 are fixedly inserted into both ends of the balance wheel bushing 5. This structure is used to assemble the balance wheels 13. The two balance wheels 13 and the shock-absorbing fork 7 form a stable support plane. The two balance wheels 13 are symmetrically located on both sides of the frame body 2, which can help the trainee maintain balance during training, conduct safe training, and improve training efficiency. The outer circumference of the balance wheel 13 is optimally covered with rubber, which can effectively absorb vibrations during training. The balance wheel bushing 5 has an internal thread structure, and the axle of the balance wheel 13 has an external thread structure. The axle of the balance wheel 13 is fixedly connected to the balance wheel bushing 5 by the thread. This structure facilitates installation. The balance wheel 13 can also be finely adjusted for symmetry during installation. In addition to using a threaded structure for installation and positioning, two balance wheels 13 can share a rotating shaft. The rotating shaft is connected to a nut, which is tightly pressed against the two ends of the balance wheel bushing 5. Then, the balance wheel 13 can be rotatably mounted on the rotating shaft of the balance wheel 13. In addition, the rotating shaft of the balance wheel 13 can also be axially stopped and positioned with the balance wheel bushing 5 using other connection methods. This is an equivalent replacement structure that can be easily conceived by those skilled in the art based on this patent and is within the scope of protection of this patent.

[0031] A safety support rod 11 is also fixedly installed at the rear end of the frame. The safety support rod 11 extends perpendicularly to the axis of the balance wheel 13, and extends a certain distance beyond the outer circumference of the two balance wheels 13. The end of the safety support rod 11 facing away from the frame body 2 can contact the ground when tilted at a set angle. The safety support rod 11 at the rear end of the frame body 2 is designed to help trainees prevent the front wheel from being lifted beyond its limit, thus assisting them in completing skill training and reducing the probability of a crash.

[0032] A safety support sleeve 6 is fixedly installed on the inner side of the rear end of the frame. A safety support rod 11 is inserted into the safety support sleeve 6. At least one threaded hole 12 is provided on the outer circumferential wall of the safety support sleeve 6. A fastening screw is movably screwed into the threaded hole 12, and the end of the fastening screw can tightly abut against the outer circumferential surface of the safety support rod 11. The main frame tail tube, the safety support sleeve 6, and the safety support rod 11 form a three-tube coaxial fastening structure. This structure can realize the adjustment of the length of the safety support rod 11 extending out of the rear end of the main frame 2, thereby limiting different lifting heights. In addition to the above-mentioned length adjustment structure, the safety support rod 11 and the safety support sleeve 6 can also be directly connected by a threaded connection.

[0033] The elastic element 10 at the lower end of the shock-absorbing fork 7 is an elastic pad fixedly installed at the lower end of the shock-absorbing fork 7 or an elastic rubber wheel hinged to the lower end of the shock-absorbing fork 7.

[0034] The shock-absorbing fork 7 includes a vertical tube 71, a sleeve 72, a fork leg 73, and a fastening inner plug 74. The sleeve 72 is fixedly installed on the upper end of the fork leg 73 and is fixedly sleeved on the outer side of the lower end of the vertical tube 71. The upper end of the vertical tube 71 is inserted into the head tube 1, and the upper end of the sleeve 72 is tightly against the lower end surface of the head tube 1. The pivot of the handlebar assembly 15 is fixedly inserted into the inner side of the upper end of the vertical tube 71. A fastening nut is also provided. The fastening nut is screwed onto the outer side of the upper end of the vertical tube 71 and is tightly against the upper end surface of the head tube 1. The fastening inner plug 74 is coaxially fixed to the lower end of the fork leg 73. The elastic element 10 is detachably fixedly installed on the lower end of the fastening inner plug 74. The above structure makes the elastic element 10 a quick-disassembly structure. This single shock-absorbing fork 7 has a simple and lightweight structure, which effectively reduces the weight of the entire fork, reduces the manufacturing process of the fork, and lowers the manufacturing cost of the fork. The elastic element 10 is preferably made of car-grade high-elasticity cushioning pad, which can perfectly absorb the impact force during training, reduce muscle fatigue, and improve training efficiency.

[0035] When assembling this invention, first install the shock-absorbing front fork 7 with elastic element 10 inside the head tube 1 of the frame body 2, and then install the pedals 9, balance wheel 13, and safety support rod into the pedal axle sleeve 4, balance wheel axle sleeve 5, and safety support sleeve 6 of the frame body 2, respectively. The assembly is convenient, the entire trainer is small in size, light in weight, and simple in structure. It can be used for training in any place, and can quickly master the requirements of skill riding, thereby improving the training efficiency of skill riding.
