Two-wheel front-wheel ride-on toy

Abstract

To provide a two-front wheel type ride-on toy capable of being safely used in compliance with a wider range of users' physical capabilities.SOLUTION: A two-front wheel type ride-on toy 1 is characterized in that the center of an axle 19 is coupled in an orthogonal direction to a lower end of a steering shaft 18 and wheels 13a and 13b are freely rotatively borne at the ends of the axle. The axle 19 includes a main pipe 20 whose center is coupled in the orthogonal direction to the steering shaft 18, a pair of axle pipes 21 that are connected to the respective ends of the main pipe 20 so that they can freely stretch or contract, and a lock member 22 that locks or unlocks the stretch or contraction of the axle pipes 21 and main pipe 20 at a predetermined position. One ends of the axle pipes 21 are engaged with the end of the main pipe 20 so that they can freely move relatively to each other in an axial direction, and the other ends bear the wheels 13a and 13b respectively. Accordingly, a gap between two front wheels can be altered in order to cope with a wider range of users' physical capabilities.SELECTED DRAWING: Figure 2

Description

[Technical Field]

[0001] The present invention relates to a two-front wheel type ride-on toy in which the axle of the front wheels is adjustable to be extendable and retractable.

[0002] A known example of a two-front-wheel type ride-on toy is that described in Patent Document 1. This ride-on toy is a foot-propelled tricycle in which the center of the axle is connected perpendicularly to the lower end of the steering shaft, and a pair of front wheels without pedals are rotatably supported on both ends of the axle.

[0003] [Patent Document 1] Japanese Patent Publication No. 2021-115917 Summary of the Invention [Problem to be solved by the invention]

[0004] The above-mentioned conventional two-wheel front-wheel ride-on toys have two front wheels so that they are less likely to tip over even when used by children aged 1 to 3 who have low motor skills, and the spacing between the two wheels is fixed in consideration of ease of steering, visual balance, etc. However, since physical abilities vary greatly depending on age and individual, there is a demand for toys with wider or narrower wheel spacing that is suited to individual users. Therefore, an object of the present invention is to provide a two-front-wheel type riding toy that can be used safely and accommodates a wider range of physical abilities of users. [Means for solving the problem]

[0005] In the following description, reference will be made to the reference numerals in the accompanying drawings, but the present invention is not limited thereto. In order to solve the above problems, the front-wheel two-wheel ride-on toy 1 of the present invention has an axle 19 connected at its center perpendicular to the lower end of a steering shaft 18, and wheels 13a, 13b rotatably supported at both ends of the axle 19. The axle 19 comprises a main pipe 20 connected at its center perpendicular to the steering shaft 18, a pair of axle tubes 21 telescopically connected to both ends of the main pipe 20, and a locking member 22 that fixes and releases the telescopic movement of the axle tubes 21 and main pipe 20 at predetermined positions. One end of the axle tube 21 is fitted to the end of the main pipe 20 so as to be relatively movable in the axial direction, and the other end supports wheels 13a, 13b. This allows the distance between the two front wheels to be changed. [Effects of the Invention]

[0006] According to the present invention, by adjusting the front wheel axle 19 to extend or retract, a two-front wheel ride-on toy can be provided that can be used safely and accommodates a wider range of user athletic ability. [Brief explanation of the drawings]

[Figure 2] FIG. 2 is a side view of the two-front-wheel type riding toy of FIG. [Figure 3] FIG. 3 is a cross-sectional view taken along the line III-III in FIG. 2. [Figure 4] FIG. 4 is a partially enlarged view of FIG. 3. [Figure 5] 2 is an exploded perspective view of a portion of the two-front-wheel riding toy of FIG. 1. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0008] An embodiment of the present invention will be described with reference to the drawings. 1 and 2 show an example of a two-front-wheel type riding toy according to the present invention. In this riding toy 1, a handlebar 11, a head tube 12, and two front wheels 13 are supported on the front side of a body frame 10, and a single rear wheel 14 is supported on the rear side.

[0009] The body frame 10 integrally comprises a head tube 12, a cylindrical main frame 15 extending diagonally downward and rearward from the head tube 12, and a back fork 16 that branches off from the rear of the main frame 15 and extends downward at the same inclination as the main frame 15. A rear wheel 14 is supported on the rear end of the back fork 15. A saddle 17 is attached to the upper rear end of the main frame 15.

[0010] A steering shaft 18 extends vertically downward from the center of the handlebars 11, passes through the head tube 12, and has its lower end fixed to the center of a horizontal axle 19. A pair of front wheels 13 are rotatably supported on both ends of the axle 19.

[0011] 3 to 5, the axle 19 comprises a main pipe 20 joined at its center in a direction perpendicular to the steering shaft 18, a pair of axle pipes 21 connected to both ends of the main pipe 20 so as to be freely retractable, and a locking member 22 that fixes and releases the extension and retraction of the main pipe 20 at predetermined positions. The joint between the axle 19 and the steering shaft 18 is covered by an axle cover 26.

[0012] The axle tube 21 is fitted onto the end of the main tube 20 at one end so as to be relatively movable in the axial direction, and supports the front wheel 13 at the other end.

[0013] Locking member 22 is fitted inside main pipe 20 and comprises locking pin 23 which can freely protrude from opening 20a onto the outer periphery of main pipe 20, and spring 24 which biases locking pin 23 in the protruding direction. Spring 24 is made of a roughly U-shaped bent spring, with locking pin 23 fixed to one end and held by holder 25 so as to be fixed inside main pipe 20. Locking pin 23 is positioned at a predetermined position corresponding to opening 20a.

[0014] The axle tube 21 has two through holes 21a, 21b formed at a predetermined distance from each other in the axial direction so that a lock pin 23 protruding from the opening 20a of the main tube 20 can pass through them.

[0015] When the ride-on toy 1 configured as described above is used by a child whose physical abilities are still immature, such as a child who has just started walking, the length of the axle 19 is set to a position where the lock pin 23 engages with the through hole 21a, as shown in Figures 2 and 3, i.e., where the axle 19 is extended, the distance between the pair of front wheels 13 is widened, and the vehicle body is less likely to tip over.

[0016] As the child grows and becomes able to straddle the saddle 17, grip the handlebars 11, and actively kick and steer, the lock pin 23 can be pushed into the through hole 21a, and the axle tube 21 can be pushed into the main tube 20 until the lock pin 23 engages with the through hole 21b, thereby contracting the axle 19. This makes steering easier, and the child can actively operate the toy and have fun playing with it, which contributes to improving the child's motor skills and developing a sense of balance.

[0017] Although an example of a two-front-wheel type ride-on toy has been described above in which the front wheels are two-wheeled and have no pedals and the rear wheel is one-wheeled, the two-front-wheel type ride-on toy to which the present invention is applied is not limited to this. For example, the present invention can also be applied to two-front-wheel type ride-on toys with other configurations, such as a four-wheel type ride-on toy with two front wheels and no pedals and two rear wheels.
