Abstract

Spoiler screen on vehicles, such as bicycles, Stroller wheelchairs and the like, characterized in that it is horizontal in the front area attached, spanned an oval and at the same time aerodynamic shape, approximately Hemisphere shape, receives and by reducing aerodynamic drag the energy required when driving as well as the protection for Improved people from the weather and insects.

Description

The The invention relates to a collapsible, removable, horizontal to be fastened spoiler screen for the protection of cyclists, occupants of Strollers, wheelchairs, Ambulance chairs, etc. against wind, rain, insects and serves to improve the aerodynamics.

panels and wind protection devices for Cycles or baby carriages are sufficient known. They are mainly because of the complicated Operation, the weak design, the weight and last but not least little enforced because of the purchase price.

task It is the object of the present invention to provide a low cost, easy to install, Foldable and removable front panel, speak "spoiler screen" for vehicles to accomplish.

Just young mothers Jogging or skating these days and pushing briskly an occupied Stroller in front of him, with the toddler, especially in the cooler season, with barely protected Face exposed to the unfavorable weather.

By the good aerodynamics of the spoiler screen due to its oval shape, - he comes very close to the hemisphere shape the effort required to push the stroller or when moving a bicycle etc. noticeable lower.

To For this purpose, a spoiler screen with i. d. R. 70 cm diameter detachably fastened in the front area of the bicycle or stroller, that he spanned as a shield against the wind or rain from works in the front. This stretching works like an umbrella, only now in a horizontal position, in which a slider on the center bar is pushed forward until it snaps or exceeds a pressure point, thereby the predominantly transparent covering over the clamping struts to get in shape.

The to be protected Person experiences adequate coverage, as the spoiler screen in height, tilt and distance with simple mechanical means, such as rails, clamps, brackets etc. manually and without tools either on the handlebars, moving together, or rigidly fitted and attached to the stroller or bicycle frame can be.

It has been proven by experiments that the cyclist in the Practice still over The opened spoiler should be able to see the slipstream best possible exploit. Nevertheless, the view remains on the road and the Traffic in front of him received unrestricted.

Around the design and the aerodynamics for higher Speeds improve as well as a tipping over the spoiler screen with tailwind To avoid is a ring on the handlebar end facing the Central pole attached. When mounting with the slider in the direction of travel 2 opposite strut ends automatically become attached via suspended thin fishing lines pulled inside so that the spoiler screen, viewed from the front, more an oval, instead of round shape corresponds. This inside and pulling backwards at the same time and is reached by the end of the 2 struts concerned on each spoiler side by two fishing lines a so-called deflection guided, united Change direction to find yourself in the back of the ring where they are are attached.

The Deflector is above the crown, but inside the fabric, so attached to the front end of the center bar so that each an end with hole over The crown on the left and one end on the right about 10 cm laterally survive and point to the back.

By the forward movement of the slider and the associated swinging the main struts up to the full form of the screen, the strings are left and right automatically cocked that she, through the diverter guided, the corresponding main struts inward a certain amount and pull down. If the spoiler screen is folded, by pushing the slider backwards against the direction of travel, loosen the deflected fishing lines and leave a complete Merging to, taking the cords remain ordered within the spoiler.

The Oval shape with down-drawn corresponding struts can also by another embodiment be achieved.

at a 2nd version Clamping the spoiler and pulling it in at the same time the authoritative 4 aspiration over the slider. When pushing forward are 2 parallel fishing lines, the in each case 2 matching main struts left and right together connect, pulled inwards and at the same time on the deflection on the Crown slightly lighter because of a double pull rope of the same material overtaken to the front. The respective Zugseil is about the deflection with the 2 matching struts firmly connected, the end of a Pulling rope on the left strut, the other on the right Strut bar is attached.

If the spoiler screen is folded, in which the slide is moved backwards, wan at the same time the tension struts to the rear and thereby pull the traction cables over the deflector forward, thereby ensuring that the fishing lines remain within the fabric.

at a third form of training is a 2nd slide behind the main slide provided on the center bar of the spoiler screen, with at least 4 Joint struts is connected. Articulated struts therefore, because these struts in the middle of a joint with stop own. Each one Ends of the articulated struts are over a joint connected to the 2nd slide, the other ends are turn over a joint with the outer ends the main struts in connection.

Of the Spoiler screen is spanned by the main slide forward is pushed until it engages in the end position or exceeds a pressure point.

Of the 2nd slide is pushed and locked in a predetermined End position, which is slightly shorter selected 4 joint struts the 4 end points of the relevant main struts slightly after pull inside.

latching mechanisms for the Sleds are known from the umbrella industry.

You choose the 4 hinged struts a bit longer, so the 4 endpoints of the relevant main struts do not diminish inside but pressed outwards. Of the Spoiler is now a little bigger, but also so the oval shape, with appropriate rotation and attachment, be achieved.

One Stop at the joints limits the opening angle, so that the joint struts when pushing forward in the end position engage and thus one rigid connection result. The joints must be centered in the struts lie.

The Merging the spoiler shield allows the joints to remain and remain tidied up with this movement under the clothing.

A 4th embodiment deviates from the 3rd to the effect that to reach the oval shape only the main slide alone forward, be pushed in the direction of travel must be where it locks into place or after a pressure point in the end position remains. A second slider is not available.

At least 4 articulated struts with the centrally located joints are on the slide stored in the same 4 pivot points of the main struts, which after Outside depressed or to be pulled inwards, depending on the selected length of the Rigid struts.

As in the third embodiment are the same joint stops in the middle of the struts also necessary here.

By to the rear Moving the slider against the direction of travel, the Spoiler be merged, with the main struts as usual move towards the center pole and the joint struts at the same time buckle at the joint.

Around a flutter of the spoiler edge zones at higher speeds Avoid, the covering may be on the outer edge of main strut to main strut get a slightly round, concave cut and / or the relevant Main struts outward or inside because of the desired show oval shape, approx. 1-2 cm shorter or just designed longer become. This should be as possible wrinkle-free and thus streamlined Lead form, where also unequal size Covering fields can not be excluded.

It is appropriate, the Spoilerschirm, as already mentioned, with a transparent plastic film, which can also be colored, too Respectively. One possible Airtight fabric covering, with individual fields that are transparent are imaginable. To vibrate during cycling or the Pushing a pushchair to stop, must the spoiler screen a certain stability, but still have a low weight. Try in this direction resulted in a weight for a spoiler of 70 cm diameter of less than 500 grams.

Of the Cyclist may not in any way in his freedom of movement be impaired in the safe handling of the bicycle, and that the ability to drive, in particular the functional ability the front lighting must be fully maintained. In extreme crosswinds or other occasions is the spoiler during of driving easily with one hand and just as easily aufzuspannen again.

Does that drive Vehicle in front of the wind, which means that tailwind prevails, so can the spoiler can be used as a spinnaker and thus a relieved progress enable.

imaginable is also the use of spoiler as an advertising medium to so that the already existing, general attention of road users and at the same time the safety of the cyclist by being seen to increase.

Around a possible Prevent theft, the spoiler can easily dismantled and z. B. be taken in a garden. Likewise is the use nothing as an umbrella.

at the description of the above should be understood that the present invention is not limited to the described embodiments limited but any other modification, substitution or addition is structural to be possible can, without departing from the spirit and scope of the claims.
