Description

The utility model relates to structural elements of vehicles, in particular to children’s sledges and wheelchairs, and is designed to move children along the snowy surface of the earth and asphalt, as well as in public buildings and structures. This utility model is designed to effectively solve the problem of using a vehicle in a city.

Sleds with a mechanism for retractable wheeled chassis are known from the prior art, characterized in that they comprise a supporting platform with skids and struts of a wheeled chassis fixed to it with a mechanism of retractable wheels consisting of a rotary pedal mounted on a leading chassis of the chassis, connected by at least one traction with a driven landing gear (RU 125154, 02.27.2013, IPC V62V 13/18).

The disadvantages of this device are the large weight and increased vibration when driving in wheel mode.

As a prototype, the sliding wheel chassis of the Universi SU-12 vehicle for the transportation of children, which is produced by VELON LLC (applicant), was selected. Said retractable wheeled chassis comprises a chassis axle mounted on the vehicle, on which hinges are located, on each of which two wheel struts are fixed, between which the wheel is fixed by means of a wheel axis passing through openings located at the ends of the wheel struts made of steel strip. The inner struts of the left and right wheels are interconnected by a jumper, to which the link of the wheel output mechanism is attached via a hinge. As axles, special M8 bolts are used, fixed with nuts with retaining rings (http://velon-d.ru/%d1%83%d0%bd%d0%b8%d0%b2%d0%b5%d1%80%d1 % 81% d0% b0% d0% bd% d0% b8-% d1% 81% d1% 83-12 /).

The disadvantages of this device are the large weight and high complexity of manufacturing.

The problem to which the proposed utility model is directed is to create a design of a retractable wheeled chassis of a vehicle for transporting children, which would eliminate the above disadvantages.

The technical problem solved by the creation of the claimed utility model consists in creating a retractable wheeled chassis of a vehicle for transporting children with less weight and less laborious manufacture.

The technical result achieved by the implementation of the presented utility model is to reduce weight and reduce the complexity of manufacturing.

The technical result is achieved in a retractable wheeled chassis of a vehicle for transporting children, containing a chassis axis fixed to the vehicle, on which hinges are located, to which the wheel struts are connected, interconnected by a jumper to which the traction of the wheel output mechanism is attached. Each wheel strut is made in the form of a curved rod, the horizontal part of which is the axis of the wheel on which the wheel is mounted.

The essence of the utility model is illustrated by the drawing, which shows a front view of a retractable wheeled chassis of a vehicle for transporting children.

Accepted designations:

1 - the axis of the chassis;

2 - hinge;

3 - a rack of a wheel;

4 - jumper;

5 - traction of the output mechanism of the wheels;

6 - wheel axis;

7 - wheel.

The retractable wheeled chassis of the vehicle for transporting children contains a chassis axis 1 mounted on the vehicle, on which hinges 2 are located, to which the wheel racks 3 are connected, interconnected by a jumper 4 to which the traction of the wheel output mechanism 5 is attached. Each wheel strut 3 is made in the form of a curved rod, the horizontal part of which is the axis of the wheel 6, on which the wheel 7 is mounted.

Execution example

The axis of the chassis 1 is made of a thin-walled steel pipe with a diameter of 16 mm. Hinges 2 are made of pipe: diameter 20 mm, length 35 mm. The jumper 4 is made of a thin-walled pipe with a diameter of 16 mm. The thrust of the output mechanism of the wheels 5 is made of a flat-oval pipe 30 × 15 × 1.0 mm or from a profile pipe of a square section 20 × 20 mm Wheel racks 3 and wheel axles 6 are a single part, which is made of a calibrated steel bar with a diameter of 8 mm, bent at an angle of about 90 degrees at the transition from the wheel strut 3 to the axis of the wheel 6. Wheels 7 are made of 150 mm diameter plastic with tires from EVA material.

Claims (1)

A retractable wheeled chassis of a vehicle for transporting children, comprising a chassis axis fixed to the vehicle, on which hinges are located, to which the wheel struts are connected, connected by a jumper to which the traction of the wheel output mechanism is attached, each wheel strut is made in the form of a curved rod, the horizontal part of which is the axis of the wheel on which the wheel is mounted.
