Definitions
- the invention relates to a foldable chair wheel with a streamlined, split and foldable covering.
- the bicycle would need improvement, especially in two areas. These are the speed and the weather protection.
- chair wheels have two main advantages:
- a streamlined hood which is located on a chair wheel, improves the C w value and thereby the speed even further.
- a hood shields wind and rain and thus offers weather protection. This would be the basic idea of all vehicles that are operated with muscle (or with other environmentally friendly energy sources), but are superior to the bicycle in terms of speed and weather protection.
- chair wheels are known in the prior art both without cladding and with full cladding. However, chair wheels have significant design problems: The steered front wheel must either be in front of or behind the circle described by the pedals and feet.
- Indirect steering via a parallelogram mechanism (such as U.S. 690733, FR.863253, AU.103479) eliminates the first problem, lateral swinging.
- the driver has a very uncomfortable feeling that he cannot stay with his hands outstretched (e.g. in the event of a collision),
- a wheel with the handlebar under the seat can be
- the long chair wheels have a better driving quality than the short ones; the better of the two long chair wheel variants, the one with the indirect steering is very cumbersome: approx. 2.3 m long, you cannot take it with you, do not turn in the stairwell.
- the chair bike with the best riding characteristics has almost completely lost the mobility of a normal bike. For that, what it can offer, the speed gain of about 4% is a pretty insignificant advantage.
- the U.S. patent 4198072 proposes a semi-ellipsoidal seat construction that can prevent slipping sideways, but this seat is only suitable for extremely low seat heights. For everyday road traffic, however, a minimum seat height of approx. 40-45 cm is required. The above-mentioned seat is unsuitable for such a seat height. One would sit too deep in such a bowl to be able to lower the legs comfortably when stopping.
- Chain part is covered with a mudguard.
- This solution would be inadequate for a wheelchair wheel that can be pushed along (which is proposed by this application), because part of the long lower and covered chains would very easily get dirty on the legs.
- Another disadvantageous aspect of the drive system of the long chair wheels is the translation.
- a chair bike must at least have the development of a sports bike, approx. 8.5 m, in order to take full advantage of the higher speed, which is made possible by the better aerodynamics. You either need a normal 28 "rear wheel and conventional 52 chainring, or a smaller rear wheel and a disproportionate chainring (eg a 20" wheel needs a 69 chainring). Covering such an oversized chainring and also the upper and lower chain part with a protective device would result in a very bulky construction. This would further worsen the chair wheel, which is already too clumsy.
- the chair wheel is shortened solely by the smaller wheel
- the "Roulandt" chair wheel (see above, line 116) uses a 25 “rear wheel and a 52 chainring and takes an uncomfortably high fit (approx. 70 cm) to an acceptable length, (approx. 1.85 m)
- the Avatar chair (Das Convention, page 144) takes a 40 cm longer length (approx. 2.25 m) to increase the comfortable seat height (approx. 55-60 cm) have where you can lower your legs when stopping without the seat edge pressing into your thigh, as in the previous example.
- the invention is based on the general object of offering a chair wheel that has good steering properties and can be carried along at the same time, has a functional seat and a reasonable chain guard, is almost as short as a conventional bicycle or can be shortened, thanks to better aerodynamics it is faster than an uncovered chair wheel is an unclothed armchair bike, its weather protection does not impair the ability to be pushed along and can easily be made insensitive to cross winds.
- Task 1 is to build an armchair bike, when steered the line of the shoulders basically remains parallel to the line of the handlebar, but the handlebar is at normal bicycle handlebar height.
- Task 2 is to improve the poor balance behavior of the short-wheelbase chair wheels.
- Task 5 is to build a chair that is especially suitable for chair bikes, which makes pressing the whole back against the backrest unnecessary and which prevents slipping sideways without the lower edge of the seat pressing the thigh.
- Task 4 is to use the smallest possible chainring and to bring the lower and upper parallel chain parts as close as possible to each other in order to be able to cover the chainring area with a relatively small chain guard.
- Task 6 is to make the chair bike foldable.
- Task 7 is to separate the two functions of the fairing, aerodynamics and weather protection.
- - aerodynamic parts result in a noticeable improvement in speed, and in a hurry that mainly plays a role in weather protection and has large dimensions that are difficult to handle.
- This part should be foldable and foldable when the weather is nice.
- Task 8 is to make the largest and therefore most side wind sensitive aerodynamic part insensitive to cross winds.
- handlebar shaft is connected to the steerer either by a universal joint, or by a gear, or by Bowden cable, or by two pretensioned wire ropes, or by an open parallelogram mechanism.
- the advantage of this is that the shoulder line and the handlebars basically remain parallel when steering, and the steering process is as automatic as with a bicycle.
- the handlebar at normal bicycle handlebar height has the advantage that the chair wheel can be pushed like a bicycle.
- Task 2 is achieved in that there is a transmission ratio of more than one to one (111) between the steering axle and the fork axle.
- the advantage of this is that a chair wheel that is too “nervous” and “sensitive” because of the short wheelbase is “desensitized”. That means: with a certain twisting of the handlebars, only as much is twisted on the torder wheel as corresponds to the turning circle of a bicycle with the same number of twisting of the handlebars.
- Task 3 is solved in that there is a support behind the cross.
- This prop is made of hard
- Foam or (and) from a firmly stretched webbing and clearly expresses the fabric surface of the backrest in the cross area, (thus following the natural S shape of the spine).
- Task 3 is also solved by combining the following features:
- the armchair is cup-shaped, but only
- the point serves against which you can brace yourself when you pedal hard. This is particularly important when approaching, because you cannot use your own weight as a driving force on the chair wheel.
- the side lifts prevent the driver from slipping sideways in fast corners, but thanks to the straight lower surface, the lower edge of the armchair does not press the thighs when the legs are lowered when stopping.
- the advantage is that a sliding chair wheel in the chainring area can be covered with a relatively small chain guard, because the chainring can be significantly smaller than the normal chainrings thanks to the transmission sprocket and the two parallel chain parts are close to each other.
- Task 6 is solved in that the suspension-ensuring rear wheel is swingable forward.
- the advantage The long and difficult-to-transport chair bike is shortened to a normal bike length and still remains portable and steerable.
- the middle part is an asymmetrical umbrella, which is covered with transparent and tear-resistant plastic film.
- the umbrella is attached to the backrest. When it rains it offers effective weather protection, but when the weather is nice or in the stairwell it can be folded up and does not bother you, so its large dimensions mean that it can no longer be pushed along.
- Task 8 is solved in that the skeleton of the otherwise covered luggage carrier basket has an aerodynamically pointed shape.
- the advantage of this is that the flexible thin plastic sheets can be removed when there is a large side wind to make the chair wheel less sensitive to cross winds. In windless weather, however, the blades can be attached to the aerodynamically shaped frame to achieve a significantly higher speed.
- the recumbent consists of a brazed steel frame, a seat, an aerodynamically shaped luggage rack, a front windshield and an upper umbrella,
- the frame consists of two almost horizontal tubes (1 and 2), white in the direction of travel, which connect the fork head tube (3) to the sprung swing arm (4).
- the straight seat surface (5) is supported on the upper tube (1).
- the seat glue construction (6) and, on the other hand, the aerodynamic luggage carrier basket (7) are attached.
- the handlebar head tube ( ⁇ ) is held at a normal bicycle handlebar height by a support column (9) firmly connected to the frame.
- the handlebar and fork steerer are connected by an Eardan joint.
- the handlebar shaft is mounted in the steering head tube as the fork shaft in the fork tube in the white known per se in bicycle technology.
- the bottom bracket shell can be moved on the lower frame tube in order to adjust the distance to the respective size of the cyclist.
- the bottom bracket shell is with a pipe piece (11) running along the pipe (2) and which has a notch on the inside.
- Tube (2) has the corresponding rail, which prevents the bottom bracket housing from rotating in a plane perpendicular to the direction of travel.
- the tube piece (11) is fixed with a screw (12) after adjustment to tube (2).
- Chain tensioning roller (13) is pressed onto the lower chain guide by a rotating spring that is common in derailleur gears.
- Rear swing arm (4) is connected to the frame by a brass bush (14).
- the ring gear (15) is fastened to the axis of the bush (14) by a ball bearing. Between the top of the swingarm and the frame.
- the seat back (6) consists of fabric that is stretched over the backrest frame.
- the backrest frame is formed from thin tubes, the tubes (17 + 17), which ensure the side inclination, form a triangular construction with the tubes (18 +11 ') running behind them. This triangular structure ensures high stability when the back is pressed firmly against the backrest. (Fig.2).
