You will find here a lot of patents
free suggestions to expand the bicycles world with accessories.
So that for example also an all-weather
property can be offered relatively cheaply.
are particularly directed at the bicycle
and parts manufacturers
1.) The strenght is to be found in serenity
However, a classic "upright position" requires us a somewhat
wearisome, forward curved seat and work; And recumbent bikes position their rider to near over the asphalt.
A high oblique backrest provides e.g. an optimal supportive lean on seating
position; Active kicking becomes powerful, efficient and at the same time more relaxed.
When lean on sitting, an anatomical support is provided, with
ergonomically optimized pedaling. It makes cycling much more relaxed and safer. The back rest is about 20 cm further back to place. The handles of the steering rod are also brought
closer to the driver; And so resembles its location of an "Easy Rider" on a Harley.
Other advantages of sitting comfortably:
* You have a not so front-wheel-heavy center of gravity and does not crash over the handlebar during an impact.
* With a safety belt, a real higher safety is achieved. It is anchored on the shell support, which is
especially stiff at the edge.
* The large back rest protects the head area, the shoulders and the hip as far as possible in case of an
* These arrangements prevent a fall out of the structurally given range.
2.) fahrRAD gear - rocking instead of cranking
All pedal-lever approaches of the past were too cumbersome or not at all gear-shiftable; And all were directly on the rear wheel axle carried. No one had
the market enough enthusiastically and so was not one of lasting success**.
However, a "Rocking lever drive" can on every bike pedal axle be Combined with a only 6 Pcs. Gear shifting.
It is equipped with a freewheel and is mounted on the pedal axle. The eye
of the freewheel bearing and the axle ends are thus furthermore form-fitting components. As usual, the lever arms are secured with screws.
The chainring remains fixedly connected to the pedal axis but has no
direct contact with the right lever. Instead of the crank, the chain rim is driven here by two lever arms to its usual driving power. Furthermore, the levers are put into a rocking
connection by means of a deflection roller (under the seat) and by means of a nylon cable.
On each of the levers there is a pedal-mounted sliding
sleeve. Together they provide the pedal function of the lever arms.
For the gear selection, the sliding sleeves are pressed away from the
foot pedal (by means of discs, arches or the like located on the outside of the pedal) against a leaf spring tension. The now freely selectable engagement to a
clutch relief (made of shafts, teeth;
or grit and rubber for stepless operation) which is formed between the lever arm and sliding sleeve, this simple and robust gear shifting results.
Against unwanted displacements, the mentioned arched spring keeps the
selected gear pressed on the clutch relief.
This spring is in each case placed across from the pedals, in the 2 mm
clearance between the lever arm*** and the sliding sleeve.
The advantages of this circuit are:
* The "Rockinger" replaces a rear wheel gear and is sufficient as
a full-fledged gear shift. The optional combination with a 3-speed chainring makes sense.
* In the case of 5 - 7 lever
arms gear - optionally three times through the chainrings - this circuit provides an optimal spread ratio - for both mountain and downhill driving.
* There is no need for a rear wheel gear and the associated Gear shifting on the
handlebars - these are quite a several parts!
* In the rear wheel finds a
free-wheeling and optionally a e-motor place, which is not loaded the chain.
* This device has only 350 g of sliding sleeve weight. It also does not
cause a 2/3-idle with otherwise usual circling leg movement.
* Provides a continuous, direct and highly efficient pedal
conversion of the footwork as required; Therefore also higher attainable tempi. Short rocking intervals are maintained as required.
* A Rockinger is easier to learn than the traditional crank handle.
* It can be easily practiced and physically well
* Both lever arms can also be removed; This allows the change of a defective freewheel.
* The whole is inexpensive to produce. And there is a need for replacement of the pedals axle ball bearings.
* The search for the desired translation ratio is solved constructively
with only a few parts.
* And, the free leg selects its course; therefore is also no rocking interruption.
One-wheel for two-forces
A optionally lever arm extended beyond the axis point, provides an advanced pedal mechanism for a second driver.
The bicycle frame is only slightly stretched, If necessary, the second saddle is clicked on the bicycle frame, and a second pair
of sliding sleeves with their pedals is clicked (the stearing grips are let into the
front back rest frame). These attachments can easily stay at home during single exits.
In the paired operation, the cyclist participates only in the opposite
riding rhythm - and each exit becomes a harmonious and perfect work placement. Both have their free choice of course.
This opens up the development and market performance with a new,
creative lightweight construction Tandem-fahrRAD! The frame is the result of respective designer-creation of a bicycle manufacturer.
4.) Oh, my ass
Another innovation, also useful for conventional bicycles, is presented
here: Especially in longer journeys, conventional
saddles are quite uncomfortable. A saddle can also be formed from two oblong, good-fit thighs / buttocks, which are mounted side by side on one axle. These carry out the
bouncing pedal movement of the driver. Such a "saddle pad" increases comfort for both men and women thanks to its noticeable relief in the sensitive step
5.) In case of heat and rain
Who likes to ride a bike in the rain, snowfall or high heat? Hardly anyone!
The fact is that our city, cargo and travel bikes only offer high
driving comfort every day if they can protect us from rain or direct sunshine.
An attachable canopy could encourage the car to leave the car more often
in the garage - to ride on a bike - see below.
A horizontal weather protection roof protects against
sun and rain. On the other hand, it also supplies the bulk of the drive power as a photovoltaic film on the aluminum roof frame or as roll blinds.
The electricity generated on the roof is fed into the solar battery
integrated into the fahrRAD frame - in tube. These 150W PV films **** harvest all day, even in diffuse weather conditions, daylight. The approximately 1.1 m²
roof creates sufficient energy for a medium travel distance.
The lightweight, removable awning is wind-slippery; In a
longer test phase, I drove this one easily, even with strong winds, because even changing winds actually run flat. Also for conventional bicycles such a roof (behind the saddle-ankle or
on the handlebar clickable) would be interesting.
The four roof corners conceal the blinkers of a turn-off
indicator. The lights fed from the battery should be supplemented by a brake light because of the dangers in today's traffic density. A dawn
sensor could take over the reliable on / off switching of night lighting.
A wind- and visibly transparent net-store protects
against rain as well as against too strong sun. It is used by
Velcro fastened to the roof frame. The store has sewn a lead band at the
bottom hem and is about 55 cm deep enough. The approx. 60 x 180 cm roof can be moved forward about 60 cm in the rain and granted, that everything remains in the dry.
For sporty cyclists, this top can also be enjoyed without an electric
drive (covered with perlon instead of PV foil, weighs only about 700g) *****.
6.) Hand Protection
In order to avoid common microtraumata in the wrist, a
cylindrical, elastomeric tube-plug connection could be provided for the shock-relief, in the steering grips and their transitions to the steering bracket. This
stiff-elastic bridge could be differentiated on the weight of a person to be available, respectively, different deeply.
7.) The small cargo
The area behind the oblique backrest provides plenty of storage space for
luggage, e.g. also one - two children place. Also conceivable would be a light, removable and lockable stretch-mesh basket with a full-length folding lid, which can be
pushed with a light hand after the purchase like a travel bag on four castors. This basket can also be made of light pasture, as a practical 4 wheel
The children 's seats would also be fastened with a
click fastener; They may have side wheels under the seat and a guide bracket that can be pulled out of the back part. Such a child seat would become a stroller after the
With a special frame, fahrRAD could be designed
as a cargo wheel with a low-lying and generous loading area. Also conceivable is a three-lane variant (possibly with attachable support wheels raised in
By means of a (PV) rain cover, the transport goods fixed with
quick-clamping straps are optimally protected.
8.) Tire & wheel - Airless tire?
