Adjustable footrest for a child's bicycle

Abstract

This utility model provides an adjustable pedal for a children's bicycle, relating to the field of pedal adjustment technology. As shown in the figure, this utility model features multiple anti-slip protrusions on the contact surface in the middle of the foot, and contact components that allow for axial rotation adjustment to fit the foot on both sides of the middle. During practice riding, the user's forefoot and heel flatten the rubber base plates at both ends. When the pedal rotates to a specified angle and the forefoot pedals hard, the heel is in a corresponding airborne state. Therefore, the rear foot contact rubber base plate is lifted up by the bottom fixed elastic adjustment component, thus fitting the entire heel. Since beginners tend to exert force with their heel when the pedal rotates upward, the front foot contact rubber base plate will similarly spring up to support the forefoot, further protecting the child's foot contact safety.

Description

Technical Field

[0001] This utility model relates to the field of pedal adjustment technology, and in particular to an adjustable pedal for a children's bicycle. Background Technology

[0002] As the primary tool for young children to learn to ride, children's bicycles need to be designed to suit the rapid physical development of children. The pedals, as the core component that comes into direct contact with the feet, are particularly important for their adaptability. Traditional children's bicycle pedals are mostly designed with fixed size and position, and the pedal length, installation angle, and distance from the frame are not adjustable. This has gradually revealed obvious limitations in actual use. With parents paying more attention to children's sports and health and the development of humanized design for children's products, the market demand for pedal designs that can adapt to children's growth pace and meet their individual needs is becoming increasingly urgent. Against this background, adjustable pedals for children's bicycles have emerged.

[0003] However, existing bicycle pedals are often designed with a flat surface. When children first learn to ride a bicycle, their feet do not have enough contact area with the bicycle. As a result, their feet often slip off the pedals during the rotation process. On the one hand, children may be afraid of this sudden situation and develop a dislike for learning. On the other hand, the pedals continue to rotate when the child's feet slip off, which can cause secondary injury to the child's feet.

[0004] Therefore, we provide a children's bicycle with adjustable pedals to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable pedal for a children's bicycle, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable pedal for a children's bicycle, comprising a pedal fixing bracket and a foot contact and following adjustment mechanism, wherein the foot contact and following adjustment mechanism is provided on one side of the pedal fixing bracket;

[0007] The foot-fitting and following adjustment mechanism includes a rotary support positioning component, a central bearing type foot pedal rotary component, a shaft rotation adjustment type fitting component, and a fixed elastic adjustment component. The rotary support positioning component is provided on one side of the foot pedal fixed bracket. The central bearing type foot pedal rotary component is provided on the surface of the rotary support positioning component. The shaft rotation adjustment type fitting component is provided on one side of the central bearing type foot pedal rotary component. The fixed elastic adjustment component is provided on the inner side of the central bearing type foot pedal rotary component.

[0008] Preferably, the rotating support positioning assembly includes a hollow fixed base, a hollow fixed support rod, and a threaded rod. The hollow fixed base is welded and fixed to one side of the foot pedal fixing bracket, the hollow fixed support rod is fixedly connected to the inner side of the hollow fixed base, and the threaded rod is threaded to one side of the hollow fixed support rod.

[0009] Preferably, the center bearing type foot pedal rotating assembly includes an inner bearing sleeved center rod, a welded foot pedal bracket, anti-slip protrusions, and a preset slot. The inner bearing sleeved center rod is rotatably sleeved on the surface of the hollow fixed support rod. Welded foot pedal brackets are welded and fixed on both sides of the inner bearing sleeved center rod. Anti-slip protrusions are adhered to the top of the welded foot pedal bracket. A sufficiently deep preset slot is opened at the front end of the welded foot pedal bracket.

[0010] Preferably, the axial rotation adjustable fitting assembly includes a fixed clamping plate, an axial rotation sleeve rod, and forefoot and heel fitting rubber sole plates. The fixed clamping plate is fixedly connected to one side of the top of the pre-cut groove. The axial rotation sleeve rod is sleeved on the surface of the fixed clamping plate. The forefoot and heel fitting rubber sole plates are welded and fixed to one side of the axial rotation sleeve rod.

[0011] Preferably, the fixed elastic adjustment assembly includes a fixed support base plate, a damping telescopic strut, and an elastic sleeve spring. The bottom of the pre-cut slot is fixedly connected to the fixed support base plate, the upper end of the fixed support base plate is movably connected to the damping telescopic strut, the outer side of the damping telescopic strut is sleeved with an elastic sleeve spring, and the upper end of the damping telescopic strut is fixedly connected to the bottom of the rubber sole plate that fits the forefoot and heel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] As shown in the figure, this invention features a foot-fitting adjustment mechanism. Multiple anti-slip protrusions are provided on the fitting surface in the middle of the foot, and fitting components with adjustable axial rotation are installed on both sides of the middle section. During cycling practice, the user's forefoot and heel flatten the rubber base plates at both ends. When the pedal rotates to a specified angle and the forefoot pedals hard, the heel is in a corresponding airborne state. Therefore, the rear foot-fitting rubber base plate, through the limitation of the bottom fixed elastic adjustment component, lifts up the entire foot-fitting rubber base plate, thus fitting the entire heel. Furthermore, since beginners often use their heel to exert force when the pedal rotates upwards, the front foot-fitting rubber base plate will similarly spring up to support the forefoot, further protecting the child's foot-fitting safety.
