[Prior art]

 The structure of a well-known one-footed scooter, as shown in FIGS. 1 and 2, is mostly composed of a frame 10 and wheels 20, and the braking device is provided after the frame 10 as shown in FIG. At the end, one connecting piece 101 is provided between the connecting piece 101 and an appropriate portion of the connecting piece 101, and a braking plate 102 covering the wheel 20 is circumscribed. By stepping, a friction is generated between a part of the inner end surface of the brake plate 102 and the wheel 20 to generate a braking effect. However, in such a known structure (FIG. 2), when the brake plate 102 is stepped on, the brake plate 102 starts to bend from the connection piece 102 because the connecting piece 101 belongs to a rigid structure and does not have any elasticity. However, friction is generated only slightly between the rear portion and the wheels 20, that is, since the main working portion of the brake plate 102 is only the rear portion, a braking effect cannot be generated for the entire brake plate 102, In addition to waste of material costs, if mud adheres to the radial end surfaces of the wheels 20, or if the road surface is downhill, the braking effect is further reduced and the user is in danger. This was a drawback of the well-known single-foot scooter braking structure.

[Problems to be solved by the invention]

 The main object of the present invention is to provide a kind of single-footed scooter with a step-type safety braking structure, which has an elastic pedal connected to wheels at the rear of a vehicle body frame, and has a pedal. A connecting projection projecting below one end of the brake plate is provided, a braking plate is pivotally connected to the connecting projection, and a connecting portion connected to the connecting projection of the pedal on each of the front and rear sides of the upper end of the braking plate. An active part is provided between the active part and the pedal, and elastic means is provided between the active part and the pedal, so that the single-footed scooter can generate a two-stage safety braking, and has a special effect of easily cleaning dirt on wheels. It shall be a braking structure.

[0004]

[Means for Solving the Problems]

 According to the first aspect of the present invention, an elastic pedal is connected to a wheel at a rear portion of the vehicle body frame, and a connecting protrusion protruding below one end of the pedal is provided, and the connecting protrusion is braked. A plate is pivotally connected, a connecting portion and an active portion are provided on both sides of the upper end of the brake plate before and after the connecting protrusion of the pedal, and elastic means is provided between the active portion and the pedal. It has a step type safety braking structure for a one-footed scooter. According to a second aspect of the present invention, there is provided a step-type safety braking structure for a one-footed scooter according to the first aspect, wherein the pedal has a substantially arc-shaped structure. According to a third aspect of the present invention, there is provided a step-type safety braking structure for a one-footed scooter according to the first aspect, wherein a groove is formed on the inner end surface of the braking plate so as to be recessed upward toward the plate body. I have.

[Embodiment of the invention]

 As shown in FIGS. 3 and 4, the main structure of the present invention is provided at the rear of the frame 30 between the wheel 40 and an elastic pedal 301. An arcuate structure is provided, and a connection protrusion 302 is provided at an appropriate position below one end of the pedal 301, and a brake plate 303 is connected by the connection protrusion 302. An articulating part 304 and an active part 305 are provided, which are pivotally connected to the articulating convex part 302 of the pedal 301, and elastic means 306 is provided between the active part 305 and the pedal 301. Thus, the one-legged scooter of the present invention is provided. A step-type safety braking structure is provided.

As shown in FIGS. 5 and 6, when the operator steps on the pedal 301 in the first step, the connecting part 304 at the front part of the brake plate 303 is applied through the connecting convex part 302 at the front end of the pedal 301. At this time, the connecting projection 302 at the rear stage of the pedal 301 is provided with the elastic means 306 and the external force applied to the pedal 301 is not yet greater than the elasticity of the elastic means 306. 302 still has the support of the elastic means 306 and is located at the upper end of the active part 305 of the brake plate 303, and the rear part of the brake plate 303 is not in contact with the wheels 40, so that it has a buffer function.) The front part of the brake plate 303 first compresses the wheels 40 to form friction, providing the braking effect of the first step, and performs slight deceleration and braking. In addition, the front part of the brake plate 303 and the pressure and friction of the wheel 40 simultaneously provide another effect that the front part of the brake plate 303 simultaneously removes dirt attached to the wheel 40. When the operator of the one-footed scooter fully depresses the pedal 301, the pedal 301 passes through the connecting projection 302 at the subsequent stage, pressurizes the lower end of the active portion 305 of the brake plate 303, and indirectly applies the brake plate 303. The inner end surface of the scooter according to the present invention can be stepped down, even when traveling downhill or on a muddy road, by completely contacting the inner end surface of the vehicle with the radial end surface of the wheel 40. Due to the braking structure, an extremely excellent braking effect can be achieved.

Further, a design of a protruding ring 41 is provided on a radial end face of some of the wheels 40, and a groove 307 compatible with the protruding ring 41 of the wheel 40 is formed on an inner end face of the brake plate 303 ( Thus, the braking effect of the braking plate 303 can be effectively increased.

[Effect of the invention]

 Taken together, the single-foot scooter's step-type safety braking structure of the present invention provides a two-stage safe braking of the one-foot scooter, and also offers a special effect that makes it easy to clean the wheels from dirt. It has the nature and inventiveness, and it completely meets the requirements for utility model registration. It should be noted that any modification or alteration of details that can be made based on the above description belongs to the claims of the present invention.
