The invention relates to biotransport engineering, mainly to velotron, namely the design of a Bicycle with a pedal-and-rod drive with adjustable torque.

Famous bike with Dobby node and the saddle, United pipe and fixed through the holes and screw respectively anthropometry for lack of adjustment of the driving torque.

Closest to the proposed to the technical essence is the bike "Maxi". It consists of RAM and installed it wheels, steering and pedal-and-rod drive, extension rods which corresponds to the length of the longitudinal groove on the lower end of the seat tube or guide Dobby unit, which moves along the seatpost tube by means of a control device of a cable connected to a guide or pipe connecting the guide with a rack saddle and fixed in the rear sector podshadley pipe control device. Lack of bike "Maxi" is the inconvenience of operation for the rear location of the control device and over the trunk of the bike in the tourist layout. In addition to the inconvenience of using the space needed to move the lever device may be filled with the contents of the trunk, and impede the movement of the control lever. In addition, the availability of moving parts connecting rod external influences may affect the stability of their health. The elongation of rods is limited anthropometric data biker long legs.

The purpose of the invention to improve the convenience of operation vne limits increasing the length of the rods.

This is achieved through a forward location of the device that controls the position of the saddle and Dobby unit on a horizontal pipe with simultaneous moves them in opposite directions on the seatpost tube, so that the distance between the top point of the saddle and the bottom of the exact trajectory of the pedals under the maximum torque increases from a condition of preservation of its compliance with anthropometric data of the cyclist, however, a counter movement Dobby unit and seat at the same time, creates the possibility of increased elongation of a rod.

The essence of the invention lies in the fact that the cyclist "Maxi-1", containing mounted on the frame of the wheel, wheels, braking system and pedal-and-rod drive rods of adjustable length, provided with a guide Dobby unit and stand seat installed in the oval seatpost tube enables simultaneous move it in opposite directions, which guide and rack are connected to the ends of the control cable, the median part of which is withdrawn through the hole in the seat tube and connected with a control device installed on a horizontal pipe frame, and when the volume of the lower branch of the control cable is in contact with the upper generatrix diametrically support in the seatpost tube, and the upper branch is in contact with the support on this lower sector and its guide Dobby unit is connected with the lower end of the bar saddles additional managing cable in contact with the upper generatrix (sector) of a support mounted in the longitudinal groove of the rack saddle and mounted on the seatpost tube.

The case of each rod bike "Maxi-1" consists of connected with the cylinder, the guide part forming a cavity for placing an extension cord, equipped with a Central longitudinal hole to accommodate the bolt of the latch with the locking element on the inner end and the hole for the pedal shaft on the outer end of at least one of the shelves housing the connecting rod is equipped with virturally on the inner surface to accommodate the end of the locking element in the working position and at least one side of the strip is provided with a longitudinal groove for limiting movement of his screw mounted in the hole of the corresponding side of the body.

Seatpost tube of circular cross section of the frame of the bike "Maxi-1" in addition to the longitudinal groove at the front of the saddle is provided with a longitudinal diametrical groove on its lower end and on the guide Dobby knots who her bike "Maxi-1" can be accomplished with a single control rope with subsequent contacting him after fastening the end, for example, at the lower end of the bar saddle: with the upper side of the latch seat, with the lower side of a support at the upper end of the guide Dobby unit, then from the top sector support output cable holes and securing it on the control unit and laying of the end of the rope through the hole around the underside of the support hole and the upper side of the lock (support) saddle rack with fixing it on the lower end of the support saddle.

In Fig. 1 shows a Bicycle "Maxi-1", side view; Fig.2 a longitudinal section of the seat tube with a control cable; Fig.3, 4 section a-a and b-B in Fig.2; Fig.5 rod bike "Maxi-1", in Fig.6,7 a view along arrow a (to the stopper fixing device) in direction of arrow 5 in Fig.5 (to connect the pedal with rod fixing means).

The bike consists of a frame with a front wheel 2 and the wheel 3. Driven sprocket wheel 4 is connected by means of the tension of the chain 4 with a leading asterisk 5 on the axis of the Dobby unit, a guide which is installed in the seat tube 6 oval cross-section with the possibility of moving it, as the front seat 7 Fig.3, 4. On the horizontal tube of the frame 1 is fitted on the drive seat and the guide 8. On the th biggest move around the front 7 of the saddle (Fig.2). Front seat 7 is provided with a longitudinal groove 10 in which is installed a bearing 11 mounted in the seat tube 6, with the top of this pillar contacts the upper branch 12 of the control cable, extracted through the hole in the pipe 6 and is fixed to the actuator 8, the contacting it with the bottom side of a support 13. With the top of this pillar contacts the lower branch 14 of the control cable, the lower end of which is secured to the upper end of the guide 9. At each end of the axis of the Dobby unit has a connecting rod consisting of connected to the head 15 (Fig.5) of the housing 16 holds the extension 17, provided with a longitudinal hole for the fixing of the rod 18. On one end of the fixed stop 19 (Fig.5, 6), on the other made the hole 20 to the axis of the pedal, and to the end of this strip is made wepreserve 21, on the shelves of the housing of the connecting rod to the stopper 19 has wireservice 22 and on one side of the extension performed a longitudinal groove 23 to accommodate the end of the limiting move it to screw mounted in the housing bore (not shown).

The bike works as follows. Driven and managed by it in a known manner by means of pedaling Shatunova Dobby site is located in the lower position with the extension 17 in the housing 16, the trajectory of the pedals (conventionally depicted by thin lines in Fig.5) is carried out by a small circle (shown dot-dash in Fig. 1), and the saddle is at the upper position and the distance between the top point of the saddle and the bottom point of the trajectory of the pedals 1 and maximum corresponds to the anthropometric data of the cyclist (the length of the legs). In the transition movement on the inclined section of the route is on the rise cyclist moves the pen drive 8 around its axis by 180about(Fig.1), resulting in the lower branch 14 of the control cable, moving on the support 13, raises the guide 9 Dobby node and the node with the pedal in the upper position (dashed line in Fig.2) and the actuator 8 is fixed in position, for example, by means of a ratchet device (not shown). The upper branch 12 will weaken and hour 7 falls down under its own weight of the cyclist. Then the cyclist in turn sets the rod in a vertical position and by expanding the foot pedal 90abouton the rod, and with it the latch 19 is also on the 90aboutand all it will frezerovok 22 of the housing 16, and the extension 17 will have the opportunity to move around the body until it stops restrictive of Vinitaly to the stop screw in the end of the groove 23 and the alignment of the stopper 19 frezerovok 22 on the outer end of the casing and turn the pedals in the opposite direction of extension is recorded from the moving body, because the ends of the stopper will be included in wepreserve and lock the extension in its extended position. After that, the cyclist cranks the axis of the Dobby unit 180aboutand sets the second connecting rod in a vertical position and in this way puts the extension it locks in its extended position and continues pedaling in a known manner, during which the pedals move in a large circle, which significantly increases torque, providing overcoming lift at high speed and facilitate pedaling.

After climbing cyclist shorter rods in the reverse order and fix the extension in a shortened position, relieves the saddle from its weight, expands the pen drive 8 in the opposite direction. The upper branch 12 of the cable is stretched and moving around the pole 11, it pushes the rack 7 of the saddle and the saddle in the upper position, and vacated the lower branch 14 extends under its own weight Dobby node is lowered into the lower position, after which the cyclist pedalium around the circumference of the small diameter. The base distance between the top point of the saddle and the bottom point of the trajectory of the pedals l l 2l

Technical and economic efficiency of the bike "Maxi-1" is to improve operational properties by private execution mechanism of fixing rods reliability.

Together with the operational capability of the bike improved because of the oncoming movement of the saddle and Dobby unit that creates the possibility of redistribution of the base distance in the direction of greater elongation of the rod.
