Bicycle with linear pedaling and rowing

FIELD: transport.

SUBSTANCE: guide frame 1 supports seat 6 arranged on carriage 5 furnished with retainer 41 interacting with one of frame holes 46. Two swing levers 13, 14 with pedals 15, 16 are coupled via bracket 10 to carriage 5. Backrest 8 resting on roller 9 is hinged to seat 6. Seat is varied by varying backrest inclination in locking carriage 5 relative to appropriate hole 46. For rowing, retainer 41 is disengaged from frame 1 to allow pulling steering bar 40 and straightening legs to displace seat 6 on carriage 5. Gear ratio is changed by displacing slide 34 with retainer 35 on bracket 10. Every cable 23, 24 extends from fastener 39 on bracket 10 to run around rollers 36, 37 of slide 34 and rollers 32, 33 of levers 13, 14 to blocks 21, 22 of rear wheel drive 2.

The invention relates to vehicles with a muscular drive and can be used for movement and for training.

Famous bike with a rowing movement with a movable seat "Rowbike", commercially available in the United States, consisting of a frame mounted on the rear drive wheel and the front swivel wheel, fixed on the frame rail on which the carriage seat. Thus to the frame by a hinge attached two shoulders lever, one end of which is fixed arm and the other end is kinematically connected by a chain and sprocket through an overrunning rotation of the drive wheel, and foot rests for mounted on the fork of the front wheel (see www.rowbike.com).

This bike has an awkward running feet and does not allow the additional use of a linear actuator alternate pedaling legs.

The closest prototype is the bike with the movement of rowing, consisting of a frame with a seat mounted on the rear drive wheel and the front swivel wheel, the fork of which is fixed in bearings of the frame, while the frame is provided with two guides, which are to move the carriage stops for the legs, two shoulders swinging lever, one arm of which is in fixed bearings the wheel, the rotation of which through thee is associated with the rotation of the fork of the front wheel, and the other shoulder is kinematically associated with the rotation of the drive wheel through the freewheel, the motion of each carriage is connected with the rotation of the two shoulders of the thrust lever. While the guides are positioned on the sides of the front wheel and attached to the frame hinge with a vertical axis of rotation and can be rotated sideways from the front wheel to the fork of the front wheel attached plate for emphasis rails or sliders when turning the front wheels (see EN 2402451).

However, stated the bike does not allow in addition to rowing to use advanced linear pedaling with various landing.

The aim of the present invention is, in addition to rowing to use a linear actuator pedaling with various landing.

This goal is achieved by the fact that the bike with linear pedaling and rowing consists of a frame with a seat mounted on the rear drive wheel and the front swivel wheel, the fork of which is fixed in bearings of the frame, the steering rotation due to the rotation of the front wheel, stops for the legs, the movement of which is connected with the rotation of the rear wheels via a freewheel, characterized in that the frame has a guide for the carriage seat, to which is pivotally attached to the backrest, based on the roller mounted on the frame, and the carriage C is the group is equipped with a stopper, interacting with one of the holes on the frame, rocker arms, the ends of which are attached to the supports for the legs, and the axis of the hinges swinging levers mounted on a bracket rigidly attached to the carriage with the seat, the movement stops for the legs connected by separate cables with blocks, which through its clutch associated with the rotation of the rear wheel, and the wheel is fixed in the fork of the front wheel.

To change gear ratio of the transmission, the bike makes a difference on the ends of levers fixed rollers, and the bracket is made in the form of a guide for the slide with lock for this guide. The slider attached two rollers and the cable each block around your roller on the end of the lever and its roller on the slide and the bracket in the upper part.

The invention is illustrated by drawings.

Fig 5 is a view of the City on the swinging arm and the slider.

Bike with linear pedaling and rowing consists of a frame 1 mounted on the rear drive wheel 2 and the front swivel wheel 3, the plug 4 which is fixed in bearings of the frame. The frame 1 is made as a guide for the carriage 5 with the seat 6, to which the hinge 7 is attached backrest 8, resting on the roller 9, zakreplennymi frame 1. The carriage 5 is attached to the bracket 10, the end of which is articulated by the axes 11 and 12 attached rocker arms 13 and 14 with supports for the feet in the pedals 15 and 16 at the ends. Driving the rear wheel 2 mounted on bearings 17 on the axis 18, mounted on frame 1. On the hub of the wheel 2 on the sides of it on the bearings 19 and 20 mounted drive units 21 and 22 with wound cables 23 and 24 of Kevlar. Blocks 21 and 22 associated with the rotation of the rear wheels 2 through a clutch 25 and 26 in the form of star wheels. To return the blocks 21 and 22 to its original position when the implement drive movements attached to them small blocks 27 and 28. On a small block 27 is wound the cable 29, which surrounds the tension block 30 and is wound on a small block 28. The stretch of the cable 29 of the tension block 30 is a rubber tourniquet 31 attached to the frame 1.
