Tricycle

 

(57) Abstract:

The invention relates to vehicles, in particular for transformable rental. The tricycle can be transformed in two-wheeled and back. Convertible Bicycle includes a frame and front axle. Mounted on the frame rear wheel drive and the saddle. Front axle carries two pivot forks with forks and wheels. One of the wheels associated with the wheel. The second wheel is rotated around the vertical axis of the fork. Plug connection connects the front axle to the frame and allows replacement of the bridge. The same plug connection connects one of the pillars of the forks with the front axle. This bearing plugs can be installed instead of the bridge. The proposed solution allows to adapt the bike to different road conditions. 4 Il.

The invention relates to velotron and is aimed at expanding the operational capabilities of the bike.

The bike as individual vehicles and sports equipment sometimes becomes useless due to its inherent instability. It is difficult and dangerous to ride a bike on icy roads. Can't use many of Invalidy the capabilities of the bike can be extended with the introduction of its third wheel. There are many known designs tricycles. These include the rental trailer with a sidecar bikes with two rear wheels and a Bicycle with two front wheels, including those in which the front axle is rigidly connected with the frame, and turn only forks with wheels.

It is known device disclosed in the patent US 4277078 A, 07.07.81, B 62 K 5/02, in which the front end of the Bicycle frame at the location remote to the fork of the front wheel set front axle, comprising a transverse beam that carries two pivot forks with forks and wheels associated with the wheel mechanism capable of transmitting plugs torque from the steering wheel.

The closest analogue of the claimed invention is the device according to patent RU 2026228 C1, 10.01.95, B 62 K 9/00, where disclosed convertible Bicycle comprising a frame and a front axle carrying two pivot forks with forks and wheels associated with the wheel mechanism capable of transmitting plugs torque from the steering and front axle connected to the frame detachable connection, allow for replacement of the bridge support the fork with the fork and front wheel to convert the tricycle in du swivel forks with forks and wheels, one of which is connected with the driving mechanism capable of transfer plug torque from the steering and front axle connected to the frame detachable connection, allow for replacement of the bridge for converting a tricycle to a two-wheeled, characterized in that one of the pillars of forks associated with the bridge in the same plug connection to be installed instead of the bridge, and the second wheel is made with the possibility of rotation around the vertical axis of the fork.

The list of drawings. Fig.1 is a top view of a tricycle. Fig.2 is a top view of a tricycle. Fig.3 - bearing fork with a fork, wheel and rudder. Fig. 4 - the bridge (view from the side of the docking station; supports plug rotated to the vertical position).

Tricycle contains: 1) a frame 1 with a rear wheel 5, the actuator 6 and seat 7; 2) support 9 of the fork with the fork 12, the wheel 10; 3) bridge 3 with the second plug 12, the wheel 10, the wheel 11 and the steering trapezoid 13.

Frame 1 bridge 3 bridge 3 with the support 9 of the plug are connected to two identical plug connection 4. There are two options for Assembly.

To build a two-wheeled bike bearing 9 of the fork with the fork and wheel shown in Fig. 3, are mounted directly to the frame 1, and the wheel 11 is installed in the bridge 3, the bridge is attached instead to the frame and the wheel associated with the second fork of the bridge over the steering trapezoid 13.

Drive, wheels, forks, handlebars and saddle are not different from mass-produced.

In the first embodiment Assembly axle on one fork and one wheel remains unused, and the second variant used all parts of the kit.

The transformation of the two-wheeled bike tricycle and tricycle in two very simple and does not require any professional skills.

The design allows you to quickly adapt the bike to different road conditions, in particular for driving on icy roads. Removing front axle, you can get the bike to store in accommodations even through a very narrow door, which represents an additional advantage of the design.

Convertible Bicycle comprising a frame and a front axle carrying two pivot forks with forks and wheels, one of which is connected with a driving mechanism capable of transfer plug torque from the steering and front axle connected to the frame detachable connection, allow for replacement of the bridge for converting a tricycle in duckles the place of the bridge, and the second wheel is made with the possibility of rotation around the vertical axis of the fork.

FIELD: transport engineering.

SUBSTANCE: invention is designed for converting standard bicycle into tricycle by fastening car instead of front fork. Connecting device 3 of car 1 has upper and lower parts with axle tilter relative to bicycle frame 8 to provide tilting of bicycle frame 8 to side of cornering. Connecting device 3 consists of upper and lower brackets on car 1. Plate fastened to frame 8 through hole for passing front fork of bicycle is hinge-connected with upper bracket of connecting device 3. Tube consisting of two parts connected by two cover plates enclosing tilted tube of bicycle frame 8 is hinge-connected with lower bracket. Tube is secured in its rear part by two cover plates in unit of under-saddle intersection of tubes of bicycle frame 8. Wheels of car are mounted on cantilever axle. Synchronous operation of caliper brakes of car wheels is provided by tensioning of cable, common for two brakes, and passing along steering tube of car skeleton. When brakes are used as parking brakes, cable is tensioned and put on hooks on said tube. Sides of car are made of gauze. Hinged front board can be fixed in horizontal position. Car is provided with seat for passengers, which can be used as tent for covering loads, or as sail.

EFFECT: increased load carrying capacity of car, possibility of use with any bicycle without its modification.
