Description

Now 60 years after the end of the war, the entire outdoor leisure area has become at a technically and economically significant level field of activity developed.

On The area of cycling and canoeing / kayaking is also available already quite a few product developments, the technical finesse Hard to beat are. As an example, let me just mention some very innovative recumbent and Faltbootentwicklung referenced in the price segment between 2,000 to 4,000 euros in the market claim.

You want Today, both in the field of cycling, as well as on the Area of canoe / kayak sports for natural recreational sporty actuate, that's what the market offers for Each one of the two areas offers sophisticated vehicles for a combination of cycling and water walking offers the current state of the art however, only those listed below and in the opinion of the Writer's unsatisfactory solutions at:

1. Use of folding bike and folding boat:

It are single-seat folding boats of short design, in a backpack are stowable and thus are also carried on or on the bike.

Disadvantage:

• - The entrainment of the folding bike during waterwalking is already problematic insofar as that the wheel is not under, even in the folded state, but only stowable on deck, resulting in a less favorable center of gravity and an elevated one wind susceptibility at sea.
• - The entrainment The folding boat stowed in a backpack during the bike wandering throws that Problem on that for the remaining, on a hiking trip with feeding Luggage items like z. B. sleeping bag, tent, food is no longer sufficient transport capacity is available.

2. Use of bicycle trailers:

in this connection is the complete folding boat or parts thereof by means of a trailer on Bike carried.

Disadvantage:

• - Next The bike must then also the trailer in or on the folding boat be stowed.

An interesting solution for this is in the German Patent No. 1 147 864 from dr. med. Rolf Weitemeyer showed, after which bicycle and trailer are installed in the folding boat.

To View of the author of the design effort appears here However, to be so substantial that this as a reason for the apparently non-existent dissemination of the principle can.

3. Use pedal-driven amphibious Vehicles:

Here is an example of the German patent application DE 44 10 813 A1 to be received by Günter Gellerer:
It is an "... amphibious three-wheeled land and pedal-operated watercraft whose self-supporting body is designed as a hull."

by virtue of the design of the construction shown there as a "pure" amphibious vehicle, d. H. The change from water to land operation can be without significant Vehicle modifications are made, the following arise listed serious

Disadvantage:

• - Due the immutable Hull shape must be a compromise between land vehicle and watercraft chosen what happens in muscle-powered vehicles, in particular for longer Rafting on the water quickly to the limit of reasonableness leads (more serious Disadvantage compared to the kayak).
• - With the three-wheeler is also a serious disadvantage compared to the bicycle given as known both rolling and aerodynamic drag increase.
• - The Remain the three wheels generated in the water during the water ride another, unacceptable for a motor vehicle high water resistance.
• - To the previously listed, high driving resistance generating disadvantages then comes the fact that a paddle wheel was chosen, which compared to the propeller drive, but also in comparison has an unfavorable efficiency for simple paddle drive, not noiseless is mobile (impaired Nature experience) and the danger of weeding. such Vehicles can neither seriously nor for exercise of cycling, still considered to be exercising kayaking.

Of the listed below Invention is therefore based on the following problem: It is a practicable solution created for it be cycling and canoeing / kayaking without the help of To connect motor vehicles with each other.

This Problem is solved by the features listed in the claims 1 to 9 solved. It It is achieved that you can relax with the vehicle either in the country or on the water and coping with each other Category usual, daily Distances (boat trips about 20 km, cycling about 100 km) on ergonomically efficient way of moving and doing so, as for hiking necessary, also the corresponding baggage volume streamlined and weatherproof within of the hull.

When Another advantageous application of the invention is that in claim 8 listed feature considered that by an appropriate interior design the possibility can be created, the vehicle for overnight accommodation as well Tunnel tent to use. It can thus take on a separate Tent, thereby reducing the weight to be carried and also and dismantling time is saved.

Furthermore it is with wheels standing vehicle possible, also to camp on very uneven or wet ground.

Two embodiments are in 1 and 2 shown:
1 shows the execution as a folding kayak and 2 as a canoe, and in each case in the converted to fully-enclosed recumbent variant.

For the conversion of the still floating canoe or kayak in a fully-sleeved Recumbent bike requires the following conversion steps:

By canoe:

• 1. Opening the wheel wells ( 1 ) ( 3 ) by removing the bottom-side closure lid ( 2 ), in which case water in the wheel well rises to the height of the waterline.
• 2. Retrieve the two (20 '') wheels ( 3 ) from their flat stowage positions in the bow and stern of the boat and mounting derselbigen in the flooded wheel wells.
• 3. On a shallow bank, the canoe can be rolled out of the water, even when loaded. 7 ) prevent overturning.
• 4. The drive chain is placed (on the rear wheel) on the pinion and brought the pedal device into functional readiness.
• 5. The z. B. made of elastic spring band steel cover struts ( 4 ), the fabric top ( 5 ) is placed over it and tied at the Süllrand like a spray cover.
• 6. The last step is to attach the driver's hood ( 6 ) ( 1 u. 2 ) (made of thin Plexiglas), which has almost the same shape as the bow or stern of the canoe and therefore can be accommodated there during the water hiking space-saving.
• 7. Immediately after driving off with the vehicle now converted to a recumbent, the two side stands ( 7 ) ( 3 u. 4 ) raised manually.

At the kayak:

• Here you must first remove the covers ( 8th ) ( 4 ) can be opened completely, so that you can get from the boat to the two wheel wells.
• The further procedure otherwise corresponds in principle to the canoe, with the difference that the full panel does not result as in the canoe by a separate, attached hood, but in that the deck of the kayak of two initially superimposed shells ( 8th ), which can be used by setting up and mutual fixation to a "roofing" ( 4 ).

At the folding kayak

• When folding kayak, the design principle of the full fairing for the Recumbent bikes are considered as a mixture of the principles of canoeing and the fixed-boat kayak become: the two over each other lying Decksschalen there consist of two interlocked Wooden lattices, which also swung apart and become a kind Roof can be raised.
• As in 5 it can be seen that the upper frame segments are made in two parts, these two parts ( 9 ) (hereinafter referred to as boomerangs) lie exactly behind one another during kayaking. The deckstick (s) ( 10 ) are divided into two parts in length, and of each boomerang half, one half of the cover half is "taken along" when unfolded.The covering of the grid roof then erected takes place, as in the case of the canoe, by means of a fabric top.
• Naturally should this design principle when folding kayak not necessarily implemented but it could also on two non-interlocked, fabric-covered and one above the other lying deck shells used become.

Finally, it should be pointed briefly to the importance of good aerodynamics in cycling. In case of unfavorable aerodynamics (at appropriate speed) be already up to 80% of the drive power can only be used to overcome the air resistance. The main reason for the superiority of the recumbent compared to the classic bicycle with diamond frame is due to the significantly lower air resistance of the recumbent bike.

The present invention leads now forcibly to another significant improvement anyway already comparatively good aerodynamics of the recumbent thereby, that by the entrainment of the Canoe / kayak hull a streamlined full fairing almost natural becomes.

This Advantage along with the positive effect that not only the leg muscles when pedaling on land, but also arm, chest and abdominal muscles be claimed when paddling at sea, let the invention as one for long hiking trips predestined Sports equipment appear.
