Flashing safety device that catches the eye

The invention relates to flashing, reflex-reflecting and eye-catching safety devices with at least a primary rotatable part having means defining a predetermined axis of rotation for the primary rotatable part, and with a holder for the means forming the axis of rotation, so that the primary rotatable part under the action of the wind Can perform rotations »The primary rotatable part has a dimensionally stable body, preferably made of a flat material, essentially all parts of which run parallel to the predetermined axis of rotation. The body is at least on the parts located outside the axis of rotation are profiled, on opposite sides of the body in the form of Pattern a reflective material and a non-reflective (preferably fluorescent) material. Material applied is. The pattern of the reflective material on one side is relative to the pattern on the other side of the same material arranged axially offset. In all cases

309 848/0333

are located at least 50% of the reflex-reflective Patterns on opposite sides of the sheet material covered areas at locations with respect to the axis of rotation do not collapse when viewed while rotating the rotating part. These patterns are therefore related to one another axially offset. The arrangement is made so that essentially all botation speeds occurring in practice of the primary rotatable part around the predetermined axis an observer in reflex-reflecting conditions one gets the impression that the reflective patterns alternately blink or flash. The following are different specially designed rotating bodies and reflective patterns described.

The invention relates to safety warning devices and, in particular, safety devices which act as eye-catchers with patterns of a reflective material.

All safety warning devices according to the invention have the effect that a viewer under reflex-reflecting conditions the The impression is gained as if flashes of light were shining, the effect of the devices according to the invention extending over a full 360 ° extends.

The invention provides a security that is effective even in daylight β warning device with the additional pattern a · fluorescent Materials are used that also act like a blinking light.

In the embodiments of the invention, a dimensionally stable, profiled sheet-like material is applied to a predetermined one Axis aligned so that essentially all parts of this material run essentially parallel to this axis, around which the rotation of the material occurs, which is normally caused by the wind. The flat material is one with patterns reflective material and a non-reflective (e.g. fluorescent material) so that a viewer gains the impression of flashes of light, as will be described in detail later.

Reflex reflective patterns can be made with fluorescent Patterns are combined in the manufacture of security warning devices for vehicles, especially for slow moving vehicles such as bicycles, agricultural vehicles and the like. Such devices can also be used in a stationary manner, on track bodies or on a hill or on one parked vehicle. Furthermore, such warning devices can also be attached to a mast or to a traffic sign. If such warning devices are used in a stationary manner, and if the rotation is to be caused by air currents or winds, then appropriately chosen a location where gusts of wind or air turbulence occur, generally caused by passing vehicles causing the desired rotation. On the other hand, a power drive can also be used for such warning devices provided, although this is not desired and

itself is also not required. The invention is mainly based on the task of acting as an eye-catcher and from Safety warning devices set in revolving wind or a current of air to accomplish.

In order to achieve widespread use of such a safety warning device by young people riding bicycles, a strong desire must be awakened in them to own and show such a device. The invention provides youngsters with an interesting and moving device that is activated while riding a bicycle and that flashes constantly. A driver driving in the dark perceives this flash that attracts his attention. For driving in daylight, fluorescent patterns are preferably provided. The rotation of the device is interesting for young people who ride bicycles and they enjoy it, while motor vehicle drivers are made aware of this in order to protect young people.

of course, there are many designs of such rotating devices become known, some of which are equipped with rotating reflex reflectors. Examples of such devices are disclosed in those listed below

The teachings given in these patent specifications and according to Further suitable reflex-reflecting flat materials and coverings are for the invention of Mutzen.

Reflex reflectors basically have the effect that a light beam falling on them is reflected back in the direction of the light source more or less in the form of a radiating cone with the incident light beam as the axis. The light thrown back in this way is considered to be retroreflected or reflexively reflected, as opposed to a light that is reflected from a reflective flat pool in the form of a mirror or from a polished metal surface. A light beam falling obliquely onto a reflecting surface is reflected back in the opposite direction at the same angle with respect to the vertical.In the case of reflex reflection, the light reflected back is reflected from the surface in the form of a cone with the incident light beam as the axis, even if , the light beam falls on the reflex-reflecting surface at angles that deviate considerably ^{from a right angle (d, h <, 90 0).} It is precisely this feature, combined with the greater amount of light _t that is reflected back to the light source, that forms an important basis for the invention.

Chararteristische beads reflex reflectors consist of a layer of small transparent glass beads or spherical lenses or microspheres, as well as situated below the beads opaque reflective material, preferably reflective, metal flakes or coverings (cf. _o eg, "the teachings contained in said patent specifications which relate to beads Reflex Reflectors]) ,, The light falling into a pearl or ball lens of the pearl layer is refracted and falls on the base of the

reflective material and is broken again when it is returned by the pearl. The light therefore becomes a light source in the light reflected back in the form of a radiant diverging cone.

Eye-catching and attention-grabbing safety devices according to the invention have at least a primary rotatable component, which is preferably set in rotation by the wind »Furthermore, a means is provided, which forms a predetermined axis of rotation about which the primary component is rotated. There is also a bracket for the axis-forming means provided.

In the preferred embodiments of the invention, there is the primary rotatable component made of a dimensionally stable sheet material, the main part or substantially all of the parts in the run essentially parallel to the axis of rotation. This material is preferably profiled, usually from the axis of rotation bent out progressively. The profiling should be present at least in those parts that are outside the predetermined Axis of rotation are located to allow rotation of the component by the wind. On both sides of the flat material patterned areas of a reflective material and a non-reflective material are provided. The patterned area of the retroreflective material on one side is this with respect to the patterned area Material staggered on the other side. Essentially, at least 50% of the surfaces are reflective Patterns on both sides of the sheet material at locations with respect to the axis of rotation that are seen when viewed of the rotating component do not overlap. The patterned areas of the reflective material are on both Sides of the sheet material are arranged axially offset with respect to one another. When rotating the primary component, i.e. of the flat material around the predetermined axis conveys the to a viewer under reflex-reflecting conditions Impression of slitting or blinking caused by the areas of the reflective material on both sides of the flat Material is caused. The fact is particularly important

309848/0333

" ⁷ " ./249204

that the single primary and rotatable component produces a lightning or blinking effect, as seen from the teachings of the prior art Technology is completely different, and also the fact that the arrangement of the staggered patterns in practice a resolution of the returning light by the human eye enables »

The reflective patterns are preferably on both Sides of the flat material are identical to one another, but are arranged offset with respect to one another. The predetermined one continues to run Axis of rotation for the sheet material in general, but not always along a line that is essentially with a Line coincides in the plane of the sheet material. the Offset reflective patterns on both sides of the flat material "preferably extend over." the area of the flat area located on the predetermined axis of rotation Material, which arrangement contributes significantly to that the falling back light can be resolved by the human eye as individual flashes of light.

In various other embodiments of the invention the primary rotatable component consists of a dimensionally stable body with visible surface areas that the body with Distance from the predetermined axis of rotation completely surrounded. On the body are at least two patterned areas of the reflective Material on ink he basic districts of a non-reflective material provided, which.Pattern in with respect to each other both axially and radially on the visible Surface areas are staggered. At least one of the patterns of the reflective material extends in the circumferential direction of the visible surface areas no more than 180 ° around the predetermined axis of rotation. " Preferred embodiments of the rotating body have at least three separate visible surface fairy districts on the are connected obliquely with each other, so that no pattern of the reflective material extends in the circumferential direction extends more than 120 °.

9 shows a schematically drawn cross section through a rotatable part of a sheet material for a safety device according to the invention, wherein the axis of rotation is offset with respect to a line passing through the Plane of the rotatable part runs.

The safety device shown in FIGS. 1 and 2 will first be described. This device has a rotatable component 10, which consists of a dimensionally stable flat material. The expression "dimensionally stable ¹¹ is intended to denote a rigid or semi-rigid or also somewhat flexible material which returns to its original shape after a possible deformation under the action. Such materials are generally relatively rigid. This component 10 is set in rotation by the wind The stub shafts 12 and 13 together form a means 11 which predetermines an axis of rotation about which the component 10 rotates or disk-shaped, the axle pins 12 and 13 can be manufactured in one piece together with the component 10, for example from organic plastics such as polystyrene, polyethylene, polyvinyl chloride or from one of the many known organic plastics and also, if desired, from aluminum or others Metal sheets.

309848/0333

An annular frame forming a closed loop 14, which is provided with a stiffening rib 15, serves as Protection for the rotatable component 10 and takes the axle pins as bearings 12 and 13 on. The axle pins 12 and 13 sit in bearing bushings 16, 17 which are manufactured in one piece with the frame 14. A retaining bracket 18 can be riveted or otherwise fastened to the frame 14, in particular to a reinforced part 19 who, in turn, are attached to a round bar, e.g. »on the handlebar a bicycle or the like can be attached. A similarly designed one acts with the bracket 18 for fastening Bracket 20 together, which two components are held together by screws 21 »It should be noted that the Clamp 18 for attaching the frame 14, for example, to a bicycle handlebar is preferably attached to the frame 14 at a location that is not aligned with the axis of rotation 11 or is located perpendicular to this. The rotatable component 10 therefore rotates about an axis that is inclined to the location of the EL clamp 18 is located, the angle between 0 ° and 90 ° so that the light pattern reflected by the device attached to a bicycle handlebar assumes the desired position.

Now the patterns of reflective material on the device will be described, those on the rotating primary component 10 are provided, which consists essentially of a dimensionally stable sheet material, as already stated. In the case of this flat material, essentially all parts run essentially parallel to the predetermined axis of rotation. This flat material is bent at a distance from the axis of rotation, preferably at the front and rear edges, as shown in FIG. 2. This profile causes a Rotation of the component 10 under the action of the wind, or in other words, catch the oppositely bent edges the air flow, which in turn sets the component 10 in rotation.

The flat material 10 is on one side with a patterned area 22 made of a reflective material provided, which may consist of a flexible and prefabricated film 22 which is attached to the flat part 10 by gluing. As can be seen from Fig.1, the district includes

309848/0333

" ¹⁰ " 2 2 A 9 2 OA

all parts of the surface of the sheet material 10 from the axis & tift up to about a quarter of the axial distance between axle pins 12 and 13. The remaining three quarters of the front of the material 10 are shown in FIG. completely free from reflective material and are not reflective.

The reverse is the reverse of the material 10 according to FIG provided with a pattern of the reflective material 23, which extends over a quarter of the distance from the axle pin 13 to to the axle pin 12 extends. Apart from the two mentioned reflective parts 22 and 23 on opposite sides On the sides of the flat material 10, the remaining parts are not reflective. These remaining parts are appropriate with a covering made of a fluorescent material or of a fluorescent dye, so that they can also be used with Light up daylight. However, these remaining parts are preferably not provided with a covering, nor with one

retroreflective or mirror-like reflective material. If the rotatable disc 10 is made of a metal, that is reflected in a mirror-like manner, so are all of the muse; of the reflective material, preference is given to parts that are not covered coated with a fluorescent dye or with a non-fluorescent but diffusely reflective dye, so that the rotatable disk 10 does not reflect in a mirror-like manner. This measure is intended to be a disorder or disability of the reflective pattern can be avoided, but some but not all of the reflective Viewing from a mirror-like reflective surface in the vicinity of a reflective pattern on the rotating disk 10 would be caused.

As used herein, "viewing under reflective conditions" ¹ * is intended to refer to viewing a safety device at a location radially outside the axis of rotation for the primary rotatable component of the safety device, with the viewer's eyes near a light source, whose light falls on the safety device This applies, for example, to the driver of a motor vehicle whose headlights are switched on.

An important feature of that shown in Figures 1 and 2 Safety device can be seen in the fact that the designated 22 reflex-reflecting district can only be seen once for each complete revolution of the rotatable part 10. That The same applies to the reflex-reflecting district 23

A particularly important feature of the gate direction according to the invention it can be seen that at least $ 50 of the ones covered with your reflective pattern! laugh a * i both sides of the Flat material are located at points with respect to the axis of rotation when looking at the rotating component do not overlap. M.a.W ·, one side of the rotatable component and then looking at the other side, the result is that at least 50 $ of the reflective surface are located on one side in areas that do not reflect reflex j when the component 10 is turned over to view the other side. 3? For practice, sample arrangements are to be made prefer where $ 100 of the pattern on one side is not coincide with the pattern on the other side when the component 10 is turned over. Even if the component ranks three 10 a slight overlap of the patterns occurs, but are in all cases the reflex-reflecting areas axially offset on both sides of the component 10 with respect to each other, i.e. their relative orientation with respect to the .Axis of rotation · These reflex-reflecting areas preferably have a very considerable distance from one another on both sides of the rotatable component 10 in the direction parallel to the axis of rotation Direction with no significant overlap, but with a large, non-reflective space "

The considerable distance in the axial direction or parallel to the axis Direction in conjunction with the fact that the reflex-reflective areas when viewed under reflex-reflective conditions extend over the axis of rotation, and that one complete revolution of the component 10 must occur before each reflex-reflecting area becomes visible again, helps to give the viewer the impression of a flashing or blinking convey and enable the human eye to dissolve in practically every i? alie.

This resolvability is extremely important in contrast to the blurred perception which is the general characteristic of known devices of this type with reflex reflectors of the same type but which are not axially offset with respect to one another on the two sides of a single rotating blade. These previously known devices, in which the rotating body or wing is set in rotation by the wind, and in which the reflex-reflecting areas have an invariable distance from the axis of rotation radially outwards, so that the reflex-reflecting area on one side when viewed with the District coincides on the other side, the movement of this district occurs for an observer over an arc of a circle, whereby both districts become visible during a single complete revolution, and that at the same time. 1, which are arranged offset with respect to one another and extend over the axis of rotation, so to speak an "unfolding ¹¹ , whereby each area is only visible once during a complete rotation of the component 10 and flashes briefly. The marking of a circular arc with each Part of a reflective Bezi Rke, which runs radially outward from the axis of rotation, is essentially avoided or reduced, since in the arrangement according to FIG. 1 the reflex-reflecting areas extend over the axis of rotation. This is in contrast to the blurred impression that reflecting areas covering an arc of a circle give, which are at a distance from the axis of rotation and do not extend beyond the axis of rotation.

Of particular importance is the fact that “as opposed to the impression of a single blink for the observer device according to the invention, the effect of shifting flashes of light is retained, even if the component 10 is more than about 1000 U / mln. This effect is also maintained at all wing speeds up to storms, but that for the Practice out of the question. Perner can the invention Devices, if desired, can also be provided with means which effect a deceleration when the wind speed

309848 / 033.3

approaches the speed of the storm »For this purpose, a small brake in the form of a propeller unit on the axis of rotation · This propeller unit is essentially for the deceleration is ineffective at low speeds. At higher wind speeds, the propeller unit raises the axis of rotation and presses it against the bearing, which delays the rotation. However, this measure is not required

The reflective pattern on one side of the component should preferably be the same as the pattern on the other side. However, the pattern is often reversed on one side with respect to the other. The pattern 22 is therefore essentially the mirror image of the pattern on the other side (23) _a Although circular patterns can be used, "non-circular patterns (or patterns whose circumference is not circular) are largely preferable because The rotation of the device under reflex-reflecting conditions will cause a clearly noticeable return of the lightning flash. Circular patterns, even if. Parts inside are left out to create an image that appears noticeably different, in the case of mirror image reversal, are nevertheless not preferable, since the human The eye is somewhat overstrained with a very rapid rotation of the component 10 when a specially generated design of a non-reflective symbol within the circle is resolved. Under all circumstances, a coating with a reflective material that completely covers the pane is to be avoided as a pattern. e.g. triangles, rectangles, ov ale, crescent moons, stripes, or the like (but preferably not letters or numbers) attract much more attention and do not appear as "light bulbs". Even a relatively large ring can produce favorable results. However, massive disc-shaped Reflexreflaktoren are not preferable ₀ würfeleekenförmige contrast, reflex reflectors can be of different configuration of use, especially when used to produce the pattern with cube corners provided flexible materials.

reflective areas economically provide a variety of patterns. When using these materials insist no difficulties in providing curved or specially designed surfaces with a reflective coating. For example reflective structures with any shape can be produced by applying dye compositions, which are reflective after drying (see «U.S. Patent No. 3,251,704). However, the patterns are preferably generated in such a way that on the rotatable part 10 a pattern is glued or otherwise attached, previously made of a thin and a pearl-like surface having and reflective sheet material has been cut, the use of a material being particularly desirable is that a transparent on an exposed lens structure Cover film bears, as in US Patent No. 2,326,634 (Gebhard), the transparent cover film being attached to the underlay by means of a honeycomb-shaped line pattern forming a plurality of reflective cells.

The most preferred pattern arrangements for offsetting the reflex reflection are made up of areas that adjoin the opposite sides have an axial distance from one another which is at least about one third of the axial distance of the rotatable sheet-like material, the separation distance preferably being longer if a greater fiotation speed is assumed, while all other districts are provided with a fluorescent material covering, der.bei Daylight serves as an eye-catcher and attracts attention. The areas with the fluorescent pattern can also have an axial distance from one another, which is smaller or larger is than the distance of the reflex-reflecting areas from each other.

With the safety device shown in Figo3 an open or U-shaped frame 26 is used as a bearing for a substantially square or rectangular sheet material 27 is used, which is rotatable about a predetermined axis which is determined by the pivot pins 28 and 29. It can

The dimensionally stable flat material 27 is -on the one Side provided with a strip 31 of a reflective material, the edge 33 of which is perpendicular to the axis of rotation at one point which preferably comprises no more than about one third of the distance from the top edge to the bottom edge. On the opposite side of the sheet material 27 is another strip 32 of the reflective material provided, the edge 34 of which comprises approximately one third of the said distance from the lower edge of the sheet material 27. The reflex reflection effect of the construction according to the · Fig. »3 is the same as in the construction according to the Pig »" !.

The device shown in Figo4 can be used as a replacement for A flashing traffic and warning signs are required, however no source of power. A base or mounting plate 36 carries a single axle 35 which is only at one end in the base plate 36 is rotatably mounted. A plurality of components are rotatably mounted on the axis 35 at a distance from one another, namely a first rotatable.es part 37 »a second rotatable part 38 and optionally yet another rotatable part 39 »These rotatable parts are arranged axially offset with respect to one another, so that after of FIG. 4, each rotatable part essentially consists of a dimensionally stable one and curved sheet material, all of which. Parts essentially parallel to the predetermined axis of rotation 35. Furthermore, the first rotatable part 37 is offset from the rotatable part 38 by. The material of the rotatable Part 39 can be arranged offset radially with respect to the rotatable parts 37 and 38, as shown in the lig®4. (If desired, the rotatable parts can be connected to each other at the points on the axis by means of material webs, so that the entire arrangement has the appearance of a screw or helix; however, this is not preferable and poses is merely an aid with which the rotatable parts are given the appearance of a unitary or one-piece arrangement The rotatable parts 37 »38 and 39 are on one side with a pattern 40, 41 and 42 of a reflective material provided in the form of an arrow. As shown in Figo4, is the arrow pattern 40 on the back of part 37,

while the arrows 41 and 42 are on that side of the rotatable Parts 38 and 39 are located, which are visible when looking at the device according to FIG. The arrows are all arranged axially offset with respect to one another and preferably extend over the axis of rotation. The no arrow pattern The supporting side of each rotatable part is completely free of the reflex-reflecting in the embodiment according to FIG Material. The parts 37, 38 and 39 are suitably profiled so that they rotate under the action of the wind. When looking at the device according to Pig · 4 under reflective Conditions gives the viewer the impression that the arrow is running strands along a line and then returns to the starting point so that what appears to be a series of consecutive arrows becomes visible. This arrangement (or an alternating orientation of the arrows or other calibration signs) is particularly useful as a traffic sign, the motorist on a motorway on a road curve or the like indicates. Furthermore, drivers can also be prompted to change roads when a road has been closed is. The construction of Figure 4 is also useful as one Different arrangement for cyclists, where the arrow pattern can be replaced by another pattern.

The device shown in Figure 5 has a closed Loop-forming frame member 43, the two legs of which are attached to a base plate 44. In the one at the top Part of the frame 43 and provided on the base plate 44 bearings, a shaft 45 is rotatably mounted, the two parts of a dimensionally stable flat material 50 and 51, which are arranged at right angles to one another and axially offset on the shaft 45. Each part is curved, and substantially all of the parts of the rotatable parts run parallel to the shaft 45. On the opposite sides of the rotatable members 50 and 51 are patterns of one reflective and one non-reflective Material provided · The rotatable part marked 50 has a triangular striped pattern on one side 49 made of the reflective material, the triangular part of the pattern in the middle not is reflective. As shown in Fig. 5, are

all surfaces of the rotatable direction finders located outside the triangle with a covering made of a non-reflective material Mistake. The triangular reflective pattern labeled 49 is on the back of the rotatable Part 50. It should be noted that the pattern 49 is the inversion of the pattern 48 on the "facing the viewer of FIG. 5" Side of the rotatable part 50, i.e. the triangle is on its tip. The patterns are therefore related to axially offset from one another, and at least 50 $ that of the reflective pattern-covered surface on both sides is located at points with respect to the axis, which is during the rotation of the arrangement do not overlap. Likewise, the second flat material 51 according to FIG. 5 is made up of strips Triangular pattern 46 made of a reflective material 46 on one side, while the back is provided with a corresponding pattern of the reflective material 47 in the form of a triangle. These patterns too on both sides of the sheet material 51 are of the overall shape substantially equal to each other except that the pattern is reversed on one side and therefore another has axial orientation than the pattern on the other side. These rotatable parts 50 and 51 are all outside of the Triangular pattern made of the reflective material, non-reflective and non-reflective surfaces For example, the triangular islands in the middle on both sides of the rotatable parts 50 and 51, preferably with a covering made of a fluorescent material or dye be provided. If desired, they can all be outside of the reflective strip-shaped triangles Surfaces on the components 50 and 51 are covered with a fluorescent material. Preferably, however, the outside the boundaries of the triangles made of the reflective material located surfaces transparent.

If the apex plate 53 and the both-prepared 52 from an organic plastic _t so the hinge 54 can consist of a fait of the plastic. On the other hand, metal hinges or hinges can also be used. An axis 55 in the form of a simple strand or a birgeamen wire with a rotating ring connector 58 hangs down from the apex plate 63. The lower end of the axle string 55 is also rotatably attached at 56. The connecting element 56 is held in place by flexible members 57 which extend substantially horizontally from the legs 52 of the tripod stand. The links 57 limit the spreading of the legs 52. The dimensionally stable and profiled flat material 69 attached to the axis 55 is set in rotation by the wind. The flat material 59 is provided on one side with a triangular pattern consisting of strips of a reflex-reflecting material 60 on a non-reflex-reflecting surface, while on the other side a corresponding reflex-reflecting pattern 61 is provided, the area delimited by the triangles with a covering a fluorescent material can be provided. As shown, the pattern 61 is substantially axially offset with respect to the pattern 60. When the device is viewed under reflex-reflecting conditions, the pattern flashes at two different altitudes.

At the intersections of the ring elements 62 and 63 forming the poles of the arrangement are pivot pins 65 and 66 used, a rotatable part 67 from a flat Store material that is designed in the same way as the rotatable one Part 10 in Figures 1 and 2, and provided on both sides with the areas 68, 69 made of a reflective material is which districts are so staggered in relation to each other There is no overlap when viewed under reflective conditions · The others! laugh of the rotatable part 67 are not reflective "

The 3? Igo8 shows a cross section through a dimensionally stable Body with three separate visible surfaces 70, and 72, which are connected to each other in the shape of a triangle, as shown in FIG. These surface parts surround with Distance an axis of rotation 73. From the body formed by the components 70, 71 and 72 go the wing-like and outwardly curved Approaches 74 on which the wind acts and turns the body. The areas 70, 71 and 72 are essentially parallel to the axis of rotation 73 of the body. The visible areas 70, 71 and 72 are, for example, at locations that are axially offset from one another provided with a star-shaped body made of a reflective material in such a way that no radial overlap on one Side with respect to the other sides occurs when the assembly rotates and viewed under reflective conditions will. In each case, you want at least $ 50 that of the reflective Material-covered area on each part of the visible districts to be located in locations that are accessible to a viewer of the Do not cover the rotating arrangement under reflex-reflecting conditions in the other areas. A single one Reflex-reflecting pattern on a visible side of the body can be 3-on at the point marked 75 and another pattern at the point marked 76. That at the point

be sensitive reflective material in all cross-section Shown to illustrate that only part of the reflective Material can be seen at this point in cross section through the body. At the point marked 72 is no reflex-reflecting material shown, since hypothetically the cross-section of the body shown in FIG the plane located in the middle of the axis runs below the position of the pattern on the side 72.

In principle, visible districts that are by far a Completely surround the axis of rotation, form a cylinder and even a globe or a cone. However, the rotating body will generally formed by individual visible surface areas or planes (or by curved-planar surfaces) that surround are assembled obliquely around an axis.

FIG _e 9 shows a cross-section exhibiting a curved sheet material 77, which serves as the primary (or secondary) portion of a device according to the invention, but with the axis of rotation 78 is arranged offset from the body 77 laterally. In other words, the predetermined rotary axis 78 is not located in the plane of the material 77; however, the material is aligned with this axis in such a way that essentially all parts of the material, despite the curvature, run essentially parallel to the axis of rotation. The flat material 77 is mounted so as to be rotatable about the axis of rotation 78 by means of a mounting member 79. The ¥ ± g _o 9 shows the constructive relationship, which is not preferable, between a rotatable body (such as the sheet material 77) and the axis of rotation for this, equal to the axis 78), the body made of the material 77 for rotation about an axis not needs to be perfectly balanced.

To He rstell the Forrichtung according to the invention can A wide variety of materials are used, with practical Reasons metals and organic plastics are to be preferred, as these materials are economical and without difficulties For example, they can be shaped by fretting, so that the warning and safety devices come in very different designs can be produced »It is only essential that the reflective patterns are arranged according to the description
