Embodiment Construction

[0042] Hereinafter, a tricycle for infants provided with the drive mechanism according to the embodiment of the present invention will be described with reference to appropriate drawings.

[0043] figure 1 It is a perspective view showing the tricycle for infants of this embodiment.

[0044]"The Composition of Children's Tricycle"

[0045] Such as figure 1 As shown, a tricycle for infants (hereinafter referred to as "tricycle") A is equipped with a rotatable handle frame 3 equipped with front wheels 2 on the front side of the vehicle frame 1, and has a rotatable handle frame 3 on the rear side of the vehicle frame 1, respectively. The left and right rear wheels 4.

[0046] Furthermore, the tricycle A is provided with a seat plate 5 at the middle portion of the vehicle frame 1 , and is provided with a push rod 6 behind the seat plate 5 .

[0047] Additionally, if figure 2 As shown, the tricycle A is equipped with a shaft support portion 8 at the lower ends of the handleba...

Abstract

The invention provides a novel driving mechanism improved to switch the relationship between the driving shaft and the front wheel into three steps of fixing, racing and gearing and a tricycle for children having the driving mechanism. The device comprises a driving shaft (9), the shaft is supported at the lower end of a handle frame (3); a front wheel (2) with internal hollow structure assembled into freely turning by the driving shaft (9); a switching mechanism contained in the front wheel (2) and switching the relationship between the driving shaft (9) and the front wheel (2) into each position at three steps of fixing, racing and gearing; and the device is composed by the following modes: when the operation part (33) of the switching mechanism facing to external part from the side of the front wheel (2) is in fixed position, the front wheel (2) is in fixed state relative to the driving shaft (9) and the rotation ratio between the driving shaft (9) and the front wheel is 1:1; when the operation part (33) is in racing position, the front wheel (2) is in racing state relative to the driving shaft (9); when the operating part (33) is in the gearing position, the rotation radio between the driving shaft (9) and the front wheel (2) is changed into deceleration state of 2:1 by the gear box provided between the driving shaft (9) and the front wheel (2).

Description

technical field [0001] The present invention relates to a drive mechanism of a tricycle for infants and a tricycle for infants, and in detail relates to a drive mechanism capable of converting the relationship between a drive shaft and front wheels into three stages of fixed, idling, and variable speed, and a tricycle for infants equipped with the drive mechanism. Background technique [0002] Conventionally, it is well known that a driving mechanism of a tricycle for infants includes a drive shaft rotatably supported on the lower end of the handle frame with pedals attached to both ends via a crank shaft, and a hollow structure rotatably supported by the drive shaft. (Inner hollow shape) front wheel, the above-mentioned drive shaft and the front wheel are in a fixed state (connected state) so that the rotation ratio becomes 1:1. [0003] In recent years, a tricycle for infants equipped with a push rod or a push frame etc. at the rear has been provided. The baby's feet on t...
