Abstract

The utility model relates to wheel supports for preventing bicycles from falling, belonging to attached support wheel supports of bicycles, composed of two wheel supports and four universal wheels, wherein, two wheel supports are respectively arranged on both sides of a rear wheel of a bicycle and fixed on an upper bar of a rear fork of the bicycle. Each of the wheel supports is provided with two universal wheels, height between the universal wheels and ground surface is 2 centimeters, so the universal wheels do not play a role in the straight running of the bicycle, and the speed of the bicycle is not affected; but the utility model can limberly play a role in the sloping during the turning of the bicycle.

Description

Bicycle falls not wheel carrier

The utility model relates to a kind of bicycle and falls not wheel carrier, belongs to the additional wheel carrier of bicycle.

Now the children that sell on the market are equipped with two steamboats with not falling the trailing wheel both sides of bicycle, and this car is unlikely on general road surface and falls down, but when sharply turning travelled on the very ways face of ice is arranged, the child's bicycle of this structure still can be fallen down.

The purpose of this utility model is to provide at the technical matters of above-mentioned existence a kind of and still is unlikely the bicycle of falling down and falls and do not fall wheel carrier having to travel on the very ways face of ice.

The purpose of this utility model by following technical proposals in advance to realize:

It is made up of two wheel carriers and four cardan wheels.Wherein, two wheel carriers are installed in the both sides of bicycle rear respectively, are fixed on the upper boom of back fork of bicycle with clamping plate and Luo silk, and cardan wheel on two is installed on each wheel carrier, and cardan wheel is 2 centimetres apart from floor level.Cardan wheel is inoperative during the bicycle straight-line travelling, does not influence the speed of car, and bicycle changes when tilting and can play a supportive role neatly.

The utility model has the advantages that when sudden stop or sharply turning and can not fall down that the people rides and can not fall down on the snowy very sliding road surface that ice arranged again.Even in night, when not seeing very sliding road surface, also can normally feel at ease to travel.This kind car not only can guarantee personal safety, and is not subjected to the hardship of tumble injury, but also can eliminate because of being afraid of to fall down the nervous caused fatigue that causes.This kind car is particularly suitable for weak the elderly and middle and elementary school student of short and small stature is ridden usefulness.Needn't get off to stand when needing parking because of red light at the parting of the ways and wait when riding with this kind car.When before car, meeting obstacles such as people, car, can stagnation of movement or go slowly with walking speed, and the walking of needn't getting off, thereby can reduce fatigue.To such an extent as to this car is specially adapted to unskilledly by bike can people by bike not ride usefulness.

Fig. 1 is the utility model structural representation

Fig. 2 is installed in bicycle rear both sides scheme drawing for the utility model

Fig. 3 is the utility model principle of work scheme drawing

Describe the utility model in detail below in conjunction with accompanying drawing:

As shown in Figure 1, 2, it is made up of two wheel carriers 1 and four cardan wheels 2, two wheel carriers 1 are installed in trailing wheel 5 both sides of bicycle respectively, be fixed on clamping plate 3 and Luo silk 7 on the upper boom 4 of back fork of bicycle, by the front and back being aligned two cardan wheels 2 are installed on each wheel carrier 1, cardan wheel 2 is about 2 centimetres apart from ground 6 height.

Principle of work of the present utility model as shown in Figure 3,8 is bicycle front-wheel touchdown point, 9 is the bicycle rear touchdown point, 11,10 is left side " Tumbler shelf " touchdown point, 12,13 is right side " Tumbler shelf " touchdown point, A is that the center of gravity on the left side is pointed to point, and B is that the center of gravity on the right is pointed to point, and C, D use the not left side of falling the bicycle and right side steamboat touchdown point for children.When bicycle was static, above the people rode over, when the formed deviation of gravity center of people and Che supported the bottom surface of gravity, bicycle will be fallen down.When bicycle is advanced forward, because the very sliding cyclist of causing in road surface tilts to the left or to the right, center of gravity will depart from A place or B place this moment, for children's usefulness bicycle, will fall down because deviation of gravity center supporting heavy triangle of forces bottom surface.And the bicycle that " Tumbler shelf " is housed can not be fallen down, because center of gravity does not depart from the pentagonal bottom surface of support gravity, this bottom surface has comprised the triangle bottom surface, and big more many than it.The bicycle that " Tumbler shelf " obviously be housed than children with do not fall bicycle want stability and safety many.

Claims

1, a kind of bicycle falls not wheel carrier, it is characterized in that it is made up of two wheel carriers and four cardan wheels, two wheel carriers are installed in the both sides of bicycle rear respectively, be fixed on the upper boom of back fork of bicycle with clamping plate and Luo silk, two cardan wheels are installed on each wheel carrier, and cardan wheel is 2 centimetres apart from floor level.
