Recumbent bicycle with linear drive

FIELD: transport.

SUBSTANCE: bicycle relates to bicycles with backrests and semi recumbent position. Brackets 21 for fastening links 17, 18 is arranged ahead of handlebar 8. Con rods 11, 12 carry pedal posts 24, 25 for high position of pedals 26, 27 to prevent bicyclist lower leg striking against co rods 13, 14 in pedaling. Adjustable clamps 22, 23 allow displacement of posts 24, 25 along con rods 11, 12 to regulate position of pedals 26, 27 to match with bicyclist lengths and, hence, allow fixed position of seat 2.

EFFECT: simplified design, higher speed.

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

Famous racing bike with a linear actuator, comprising a frame with a seat mounted on a front swivel wheel that is installed in the fork with the wheel, mounted in bearings of the frame, and the rear drive wheel sprocket unit freewheel and manaton the shifter. While on the frame in bearings mounted shaft with a leading asterisk, connected by a chain with one of the sprockets of the drive wheel. Shaft with a leading asterisk on its sides provided with two crank-slider mechanisms, cranks which are opposed to each other and to the middle part of each connecting rod crank-slider mechanisms to the outer surface of the attached foot pedal. Each connecting rod crank-slider mechanisms for its end pivotally attached to its stem, located in the guide attached to the frame and that the guide rods are next to each other in the middle seat (http://www.chriskeam.com/2009/08/18/specter-trike-recumbent-racer/).

The disadvantage of this bike are very large dimensions.

Famous bike with a linear actuator consisting of a frame with a seat installed on the front swivel wheel that is installed in the fork with the wheel, mounted in bearings of the frame, and is it the drive wheel sprocket unit freewheel and manaton the shifter. While on the frame in bearings mounted shaft with a leading asterisk, connected by a chain with one of the sprockets of the drive wheel. When this shaft with a leading asterisk on both sides it is provided with two crank-beam mechanisms, cranks which are opposed to each other. To the middle part of each connecting rod crank-beam mechanisms attached to the pedal.

The cranks of the crank-beam mechanisms spaced apart from each other a distance greater than the width of the seat and the pedals are attached to the inner surface of the connecting rods. Thus the axis of the front wheel is made with a through hole, and the shaft connecting the crank-beam mechanisms, passed through this hole. Guides for the ends of rods can be articulated links, each of which one end of the hinge attached to the connecting rod, the other end of the hinge is attached to the bracket attached to the frame behind the front wheel (EN 2400391, Fig, 15).

The disadvantage of this bike is a complicated structure due to the threading shaft through the hub of the front wheel and too long a chain.

The aim of the present invention is to simplify the design and shortening the chain. This goal is achieved by the fact that the bike recumbent with a linear actuator, comprising a frame with a seat, the mouth is fixed on the front swivel wheel, established in the fork with the wheel, mounted in bearings of the frame, and rear wheel sprocket unit freewheel and manaton the shifter on the frame in bearings mounted shaft with a leading asterisk, connected by a chain with one of the sprockets of the drive wheel, the shaft with a leading asterisk on both sides it is provided with two crank-beam mechanisms, cranks which are opposed to each other and to the middle part of each connecting rod crank-beam mechanisms attached to the pedal, with guides for the ends of the connecting rods are articulated links, each of which has one end hinge attached to the rod and at the other end to the bracket attached to the frame. What's new is that the shaft with the leading asterisk is located between the front and rear wheel, next to the front wheel and the pedals are attached to the rods through the rack, for example by clamping, with the bracket attached to the frame over the front wheel and in front of the wheel.

In order that the rods do not interfere with the rotation of the front wheel rods made with l-shaped.

The invention is illustrated by drawings.

Figure 1 depicts the bike recumbent with the linear actuator on the side.

Figure 2 (section a-a in figure 1) depicts the attachment of the right pedal to the crank.

Bike recumbent with the linear actuator includes a frame 1 with the seat is m 2, mounted on the rear drive wheel 3 and the front swivel wheel 4. In the frame 1 in bearings installed plug 5 with the wheel 6 swivel casters 4.

On the frame 1 in a known manner in bearings mounted shaft 7 with a leading asterisk 8 and opposed the established cranks 9 and 10 of the crank-beam mechanisms, the connecting rods 11 and 12 which hinges 13 and 14 are attached to the cranks 9 and 10 and the hinges 15 and 16 attached to the hinge parts 17 and 18 which hinges 19 and 20 attached to the bracket 21 attached to the frame 1 over the front wheel 4 and in front of the wheel. On the rods 11 and 12 are fastened by clamps 22 and 23 rack 24 and 25 with pedals 26 and 27 at the ends. Each clamp 22 and 23 can be clamped by a bolt 28 and nut 29 secures the rack 24 and 25 on the rods 11 and 12 due to friction forces. Moving the rack 24 and 25 along the rods 11 and 12 and clamping them you can adjust them to the length of the legs of the driver. When the seat 2 can not move. The rack 24 and 25 allow to raise the pedals 26 and 27 on the most effective to drive the height and avoid during pedaling stroke of the hinges 13 and 14 on the shank of the driver. All hinges 13, 14, 15, 16, 19 and 20 are equipped with ball bearings.

The rods 11 and 12 is D-shaped, so as not to interfere with the rotation of the front wheel 4. The rear wheel 3 provided with a sprocket unit 30 with the ratchet and manaton the shifter 31. The drive sprocket 8 St. the curtain chain 32 with one of the stars of the block 30. The trajectory described by each pedal, resembles the shape of an egg, a pointed end which is in front and slightly tapered from the top so that the main stroke of the pedals is approximately a straight line. Tests have shown exceptional convenience: pedaling by the trajectory and increased speed.

Running the bike in the following way. The driver pedals 26 and 27 and controls the wheel 6.

Stated the bike has a simple design, short circuit and comfortable and effectively the trajectory of the pedals.
