Definitions

  • the invention relates to a bicycle-like two-wheel vehicle with chain drive to the rear wheel, a saddle and a front fork rotatably mounted on the frame and connected to a handlebar.
  • the frame parts of bicycles are welded or screwed to each other and to the struts of the rear wheel fork.
  • the drive takes place in a known manner by means of foot force via pedals connected to the driving sprocket.
  • the saddle and the front fork bearing are fixed relative to each other and to the frame.
  • the invention has for its object to provide a particularly suitable as a toy or training device vehicle of the type mentioned, on which the driver executes a very harmonious riding movement covering the entire body, while the weight shift taking place in two phases for driving the driving sprocket over 36o 0 is used.
  • the frame consists of four articulated parts, of which the upper frame part carries the saddle, the front frame part the front fork and the lower frame part the rear wheel and the driving sprocket of the chain drive, on the front or lower frame part Footrests are attached and a connecting rod articulated on both sides is arranged between the upper frame part and a crank which is connected in a rotationally fixed manner to the driving sprocket.
  • the axis of the driving sprocket while driving makes a circular motion around the lower joint of the connecting rod.
  • the axis of the driving sprocket is pressed down with respect to the connecting rod joint, while in the other drive phase, by shifting weight to the saddle and transferring the Weight force over the rear on the lower frame part acting as a two-armed lever, the axis of the driving sprocket with respect to the lower joint of the connecting rod is raised again.
  • the aforementioned forces are further supported by pulling on the handlebar during the first phase and forward pressure on the handlebar during the second phase.
  • the rotation of the axis of the driving sprocket around the lower joint of the connecting rod not only generates the tensile force in the chain required to drive the rear wheel, but also causes the saddle to oscillate up and down via the connecting rod and the other parts of the frame which are connected to one another in an articulated manner, an opposite movement of the footrests and a pivoting movement of the handlebar in the direction of travel. These movements give the driver the impression of riding.
  • the articulation points of the front frame part, the connecting rod and the rear frame part are each adjustable on the upper frame part. This results in different strokes and, depending on the location of these joints Seen the extent of one revolution of the driving sprocket, different torque curves.
  • the driver therefore has the power to set a preferred drive characteristic himself.
  • the saddle is also attached to the upper frame part so as to be adjustable in the longitudinal direction.
  • the driving sprocket is preferably connected to two rectilinear and equally long crank arms, which in turn are articulated with two parallel connecting rods. In this way, significantly lower tilting forces occur in the bearing of the driving sprocket than normally with a bicycle. Because of the more even bearing load, simpler and cheaper bearings, e.g. Bushings made of polyamide or another plastic can be used. Such simple bearings are also suitable for other joints of the frame.
  • a preferred embodiment of the invention provides a peder mechanism acting between the connecting rod and a frame part , which preferably consists of an articulated with the rear frame part or the connecting rod and with the respective other of these two parts via at least one spring rod.
  • the new device By jacking up the new device, it can also be used as a so-called home trainer, for the sake of simplicity, the rear wheel by a swing pusher and the front wheel by a rolling, sliding or articulated support supporting the front frame part tion can be replaced.
  • the vehicle shown as an embodiment in Fig. 1 corresponds to a normal bicycle with respect to the wheels 1 0 , 12, the front fork 14 and the handlebar 16.
  • the saddle 18 and the chain drive consisting of a front driving sprocket 2 0, a sitting on the axis of the rear wheel driven sprocket 22 and a chain 24, are commercial parts.
  • normal bicycle accessories such as mudguards,
  • 1 sprocket 48 is rotatably connected to both sides of the bearing 46 as shown in FIG. 1. Both cranks extend from the bearing 46 in the same direction and are of the same length. Each crank 48 is connected to a connecting rod 52 via a joint So attached at its free end, which acts on the upper end via a joint 54 on the upper frame part 26.
  • the joints 36 and 54 are attached to the upper frame part 26 by means of clamps 56 and 58 in the example, so that they can be adjusted along the tube which forms the upper frame part 26.
  • the saddle 18 is likewise adjustable along the upper frame part.
  • the joint 28 is also adjustable by means of a clamp 62.
  • Height-adjustable footrests 60 are attached to the front frame part 3o in the lower region.
  • the bearing 46 of the driving sprocket 2o together with the front frame part 3o is pressed down with respect to the lower joint 5o of the connecting rod 52.
  • the bearing is then raised 46 with respect to the knuckle 5 0 again when the driver verlagert.und in the next movement phase of its weight more on the saddle while on the rear frame part 32 of the lower frame portion 34 at about its support the rear wheel axle 4o with reference to the drawing against the
  • the upper frame part 26 can have a length of 85 cm and the front frame part 30 between the joints 28 and 38 can have a length of 60 cm.
  • the connecting rods 52 are 38 cm in the example, the cranks 48 are 12 cm, the struts of the rear frame part 32 are 40 cm and the struts of the lower frame part 34 are between the joint 38 and the rear wheel axis 40 mm and in the rear section 44 18 cm long .
  • the distances between the joints on the upper frame part 26 can e.g. be adjusted so that the distance between the joints 28 and 54 50 cm and the distance between the joints 54 and 36 is 25 cm.
  • the joints 42 and 50 contain ball bearings, while the joints 28, 36, 38 and 54 are designed according to FIGS. 3a, b. This will be discussed further below.
  • the embodiment according to FIG. 2 corresponds essentially to the embodiment according to FIG. 1 with regard to the upper frame part 26 and the front frame part 3o.
  • the lower frame part 34, 44 is a single connected part, because the two Side parts are united behind the rear wheel by a web part connecting them.
  • This construction gives the frame greater rigidity and allows, instead of 2 joints 42 with ball bearings, a single joint with a plastic bushing according to FIG. 3a to be used.
  • the longer length of the rear part 44 of the lower frame part 34 compared to FIG. 1 leads to a greater drive torque in the movement phase where the weight rests on the saddle.
  • this also includes an improvement in the lever transmission effective when driving, as in the arrangement of the bearing of the driving sprocket 20 in front of the joint 38, as shown in FIG. 2.
  • the vehicle according to FIG. 2 has the following dimensions: the rear part 44 of the lower frame part 34 is 38 cm, the cranks 48 are 17 cm, the connecting rods 52 are 46 cm and the other frame parts as long as indicated above for Fig. 1.
  • the struts B 1, B 2 are connected by bolts 7. 0, which is fixedly connected through holes in the struts B 1, B 2 extend and are screwed into a central threaded bore in the bolt 68 thereto.
  • the lever mechanism formed by the articulated frame, the cranks 48 and the connecting rods 52 has two dead positions which must be overcome during each revolution of the chain wheel 2o during normal travel. This is not a problem if the rear sprocket 22 is non-rotatably connected to the rear wheel 12, but requires special precautions if it is desired to do so while driving, e.g. downhill to stop the up and down movement of the saddle, but continue to roll with the vehicle. Below are two possible solutions to this problem using F'ig. 4 explained. Fig. 2 then shows yet another proposal.
  • the embodiment according to FIG. 4 uses a friction clutch 76 and 78 consisting of two interacting friction disks, which during normal driving the drag torque from the hub of the rear wheel 12, designated 72, of which only spokes 74 are indicated in FIG. 4, to the chain wheel 22 - in a vehicle with an open gear shift, the chain wheel 22 is replaced by a block of, for example, 3 or 5 differently sized chain wheels -
  • the friction between the two friction disks 78 and 78 need not be great in order to overcome the above-mentioned dead positions. 78 inside then against other slip when the rider so desires and for this purpose shifts his weight opposite to the movement phase of the saddle and the pedals, for example in a phase where he should actually let his weight act on the saddle, the footrests are loaded.
  • a releasable clutch can also be used.
  • the pressure on the friction disks 76, 78 can be changed while driving, for example by firmly connecting the nut 84 to a lever 85 on which a Bowden cable to be actuated by the driver engages.
  • the pulling wire of the Bowden cable acts in the loosening direction of rotation on the lever 85 and the nut 84, while in the opposite direction of rotation, i.e.
  • FIG. 2 contains a normal freewheel hub with coaster brake.
  • the hub can optionally also include a three-speed gearbox.
  • a normal freewheel hub without coaster brake with or without gear shift of any design can be used. Since normal freewheel hubs only develop a minimal drag torque, which is not sufficient to overcome the aforementioned dead positions, FIG. 2 shows a construction which solves the problem of dead positions in a different way. This is based on the fact that the distance between two specific points on the one hand on the rear frame part 32 and on the other hand on the connecting rod 52 is small in the dead position in which the saddle is in its highest position and is large in that dead position. in which the saddle has the lowest position. If, under these conditions, a rod designated by 86 in FIG.
  • Kiemmschelier are replaced by welded joint parts, such as shown in Fig. 3 a.
  • An essentially U-shaped, elastic bracket is provided as the lamp holder, which is attached directly behind the position of the lent rod with its one leg to part 26 and below the other leg to part 30.
