Definitions
- the invention relates to a pedal boat drive according to the preamble of claim 1. It also relates to a pedal boat equipped with such a pedal boat drive.
- a pedal boat drive with the features of the preamble of claim 1 is known from US Pat. No. 6,165,029, as is a pedal boat equipped with such a drive.
- the previously known pedal boat allows the energy transferred to the drive train to be stored in a flywheel, but is not suitable for a sporty, flexible use.
- Pedal boats are well-known watercraft and serve primarily pleasure.
- the pedal boats are provided with pedal drives which transmit energy generated by means of one or more pedal crank (s) to a propulsion means, usually one or more propellers or paddle wheels.
- the drive transmission takes place directly, ie the force is from the pedal crank (s) by means of a drive train, for. B. a chain drive and / or a propeller shaft, transferred to the propulsion means.
- the forward and backward driving of the pedal boat is controlled by the direction of rotation of the pedal cranks.
- Examples of such pedal boats are known from German utility models DE 298 20 184 UI, DE 81 17 770 UI and DE 84 04 297 UI.
- a pedal boat with a drive in which to support the propulsion, an energy store fed by the pedal drive is arranged in the drive train, from which drive energy can be drawn if necessary, in order to achieve the propulsion with reduced use of force to be able to.
- the drive is still direct here, the direction of travel is determined by the direction of rotation of the crank.
- the pedal boat should behave in the water like a bicycle on land.
- a switching mechanism arranged in the drive train for switching the running direction of the propulsion means constant direction of rotation of the crank allows easy and sporty maneuvering.
- the direction of advance of the propulsion means for example of a propeller, can be changed in the shortest possible time with continuous pedaling of the pedal crank. This helps to considerably shorten the braking distance of a pedal boat provided with such a drive by "thrust reversing" compared to known pedal boats, which is an essential property for fast pedal boats used for sport.
- a simple implementation of such a switching mechanism is obtained if, according to the invention, two flywheels are arranged parallel to one another while leaving an intermediate space, and in the intermediate space a pickup element which can be optionally coupled to the opposing inner surfaces of the flywheels, e.g. B. a roller covered with a rubber jacket is arranged. Depending on which of the insides the pickup element engages, the direction of rotation of the flywheel and thus the pedal crank change its direction of rotation and thus also the direction of advance.
- a single disk can be provided, which has a radial slot in which the pickup element is arranged.
- the switching element can also assume a further, third position in which it does not act on any of the inner sides. This position is then a neutral or idle position.
- the switching mechanism can advantageously be actuated by one or more pneumatic actuators, but other actuating mechanisms, such as. B. cables, conceivable.
- actuating mechanisms such as. B. cables
- a rubber-coated roller as a customer element z.
- the pneumatic actuators can be arranged together with an actuating lever for actuating the same in a closed pneumatic system. So there is no need to provide a pressure supply; simply actuating the actuating lever generates the pressure required in each case and applies it to the actuator to be controlled.
- the choice of a free-running axle with a flywheel also enables the arrangement of a two-stage or multi-stage transmission, preferably in the axle, in the manner of a hub gear known from bicycle technology.
- the pedal boat equipped with a drive according to the invention can be used as a sports device like a bicycle in several driving stages.
- the mass of the flywheel (s) is selected accordingly.
- a boat hull with a double hull (in the manner of a catamaran) is preferred for a sporty and agile pedal boat ride in a pedal boat equipped with the drive according to the invention.
- the pedal boat has a device for receiving a conventional bicycle and integrating it into the drive train.
- a roller can tap the propulsion energy generated by the bicycle at its rear wheel and then transfer it to the flywheel in the further course of the drive train.
- FIGS. 2a and 2b in two schematic side views the section of the pedal boat drive with the flywheel and the take-off element and the subsequent drive train up to the propeller,
- FIGS. 2a and 2b section shown in a schematic view from above
- FIG. 4 shows a view similar to FIG. 3, the pneumatic connection of the changeover actuators with the actuating lever being shown here schematically in a closed circle.
- a pedal boat 1 is shown schematically.
- This has a hull 2, which is formed by a double hull consisting of two hulls 2 connected by a connecting platform 2b.
- a seat shell 3 is fastened on a frame 4 on the connecting platform 2b.
- a drive 10 is arranged along the connection platform 2b.
- This includes a stationary crank 11 with pedals 12.
- a gear 13 is attached to the crank 11, which transmits energy generated by the drive chain 14 running thereon with the crank 11 to another gear 15.
- This is connected to a double flywheel 16 mounted on a free-running axle for power transmission.
- a take-off element in the form of a gu-mantled roller 18 is arranged, which serves to transmit the drive energy to a propeller shaft 19 and from there to a propeller 20.
- an adjusting lever 21 can be recognized, which in serves to switch the direction of advance to be described in more detail later.
- FIGS. 2 - 4 The section of the drive train near the propeller can be seen in FIGS. 2 - 4 can be better recognized and is explained below with the aid of this.
- FIGS. 2a and 2b show two schematic side views of this section.
- the free-running axle on which the double flywheel 16 is mounted is identified by 22.
- Pneumatic actuators 24 connected to the actuating lever 21 can also be seen via pneumatic lines 23. These engage on the cardan shaft 19 connected to the rubber-coated roller 18 in order to be able to adjust this and thus the roller 18 in the intermediate space 17.
- a joint 25 is provided in the cardan shaft 19 so that the propeller 20 does not change its orientation when the cardan shaft 19 is adjusted.
- a transmission gear indicated at 26 and a gear control 27 can also be recognized in FIG. 2b.
- the transmission gear 26 - similar to a gear hub on a bicycle - the transmission ratio of the drive and thus equally a "gear stage" can be selected. As a result, this leads to the possibility of sporty driving and is only due to the free-running axle 22 integrated in the drive train with the double flywheel
- FIGS. 3 and 4 The switching mechanism described above is shown in FIGS. 3 and 4 can be seen better. There is that in the space
- the double flywheel 16 located rubber-coated roller 18 each in a central position in which it does not engage any of the inner surfaces 28a, 28b of the double flywheel 16, and thus an idle position.
- the rubber-coated roller 18 brought into frictional contact with one of the inner surfaces 28a, 28b. This creates a power transmission from the double flywheel 16 to the propeller 20.
- the direction of rotation of the latter changes and thus the direction of rotation of the propeller 20 and ultimately the direction of travel of the pedal boat 1.
- control lever 21 is shown schematically in three positions, forward, idle and reverse.
- the possibility is created for the first time of using a pedal boat not only as a leisure amusement device, but also as a real sports device, similar to a bicycle, for example a mountain bike.
