    The invention relates to a tail lift with a warning mark and a warning mark for a tail lift in a motor vehicle.
    [0002] Tail lifts for motor vehicles comprise a lifting and slewing mechanism which can be mounted on the motor vehicle by connection components and which can be driven by a motor, in particular hydraulically. Tail lifts for motor vehicles comprise a platform which can be raised and lowered by the lifting and swiveling mechanism and which can be held in a selected position in particular in all swiveling positions. The platform can be pivoted from a horizontal pivot position to a vertical pivot position in which it closes the load space of the motor vehicle or is positioned behind a door that closes the load space, in particular when it is raised to the level of a load space of the motor vehicle. The platform is reversely pivotable from the vertical pivot position to the horizontal pivot position. Foldable platforms can also be stowed horizontally under a loading area of the cargo space.
    A drive is provided for the lifting and swiveling mechanism. The drive can be controlled with an electrical or electronic control device, by means of which the lifting, lowering and pivoting of the platform or platform parts can be controlled.
    For tail lifts, warning markings are prescribed that are attached to the platform and must act in the different pivot positions of the platform with respect to the motor vehicle to the rear.
    EP 1398214 A1 discloses a warning marker and a device for automatically fixing this warning marker for a tail lift of the type described at the beginning. This device for automatically fixing the warning marking on a platform of a tail lift comprises a permanent magnet embedded in the platform. The permanent magnet automatically locks the warning marking in every position of the platform parallel to the platform. For this purpose, a ferromagnetic metal strip is arranged transversely at the lower end of the warning marking.
    However, with such a fixation, an undesired detachment of the warning mark in the vertical pivoting position due to inflation can occur due to the wind in the area of the warning marking. This causes the warning marker to move while driving. This leads to increased wear.
    To avoid unwanted detachment, EP 1398214 A1 discloses on the one hand a fixation only with magnetic force, on the other hand EP 1398214 A1 suggests holding the warning mark in a holding area in addition to the permanent magnet and the metal strip by means of a positive fit of a hook.
    EP 1398214 A1 also discloses that when the platform is opened, the effect of the permanent magnet is influenced by an electrical demagnetization device, for example an additional electromagnet, in such a way that the magnetic metal strip is released and the warning marker is pivoted out of its holding position by gravity becomes.
    With this arrangement, a desired detachment when pivoting the platform from the vertical pivot position into the horizontal pivot position is possible. In addition, unwanted detachment of the warning marking in the vertical pivoting position by inflation can be prevented.
    Disclosure of the invention
    [0010] It is desirable to further improve such an arrangement.
    This is achieved by a tail lift and a warning marking for a tail lift for a motor vehicle according to the independent claims.
    With regard to the warning marking for the tail lift, it is provided that the tail lift has a platform, the platform being pivotable at least between a vertical and a horizontal pivot position with respect to the motor vehicle, the warning marking comprising a fastening means for permanent magnetic adhesion or for adhesion by form-fitting or by adhesion to the platform with an adhesive force that is sufficient for the adherence of at least part of the warning marker in at least one pivoting position of the platform that is different from the vertical pivoting position, the warning marker being designed such that the adherence of the part of the warning marker is released by a weight of the warning mark without manual loosening of the adhesion and without supply of energy in at least one other pivoting position of the platform different from the vertical pivoting position. The adhesive force and the weight are defined by a selection of the geometry and a dimensioning of the material properties of the warning markings and the fastening means within the framework of legal requirements for warning markings so that the warning markings can be securely fixed when the platform is closed and the limp warning marking can be reliably peeled off when the Platform is possible. For example, the warning marking is limp in sections and interacts with the fastening means for a peeling effect. A prerequisite for the peeling effect is that the adhesive force acting in the area of the fastening means counteracts the weight force on a joining surface between a surface of the fastening means and a complementary surface on the platform. A limp part of the warning marking peels off due to its own weight or due to an additional weight that acts on the limp part, if a weight component of the weight, which acts perpendicular to the joining surface and against the adhesive force, exceeds the maximum adhesive force that the fastening means in Applying the area of the limp part. By pivoting the platform out of the vertical pivoting position, the weight force component changes until the weight force component in the area of the limp part exceeds this maximum adhesive force. As a result of the peeling process, this part becomes detached and intensifies the peeling effect in other parts that are still attached. This enables continuous peeling. In the case of a conventional warning mark, additional weights can be attached that adjust the weight accordingly. Further additional weight for a part that is still adhering is created during the detachment process due to parts of the warning marking that have already been detached.
    A permanent magnet generated adhesive force acts in the direction of the polarization of the permanent magnet. The polarization of the permanent magnet is chosen perpendicular to the joining surface, so that a maximum adhesive force is achieved when the surfaces are arranged parallel to one another. When peeling off, the angle of the surfaces to one another also changes in the detached area, so that the adhesive force is no longer maximum. This weakens the adhesive force and increases the peeling effect.
    A pulling force acting like an additional weight on the part arises when the fastening means is not arranged over the entire surface of the warning mark. When pivoting the platform from the vertical pivoting position, a rope line is formed. The force of gravity causes the weight of the warning marking to develop a tensile force on the fastening areas of the warning marking in the direction of action of the warning marking. A force component of the tensile force perpendicular to the joining surface counteracts the adhesive force and increases the peeling effect.
    [0015] An adhesive force in the range from 0.5 N / cm 2 to 1 N / cm 2 is preferably provided. As a result of this adhesive force, a warning marking made of a tarpaulin material or flexible plastic fabric is held particularly reliably on the one hand in the vertical pivoting position of the platform and, on the other hand, particularly reliably by gravity when the platform is moved from the vertical pivoting position towards the horizontal pivoting position, i.e. replaced without external energy supply.
    [0016] The fastening means preferably comprises a permanent magnetic film or a ferritic film. The film enables a particularly suitable structure for a flexible warning marking made of layers that comprise the tarpaulin material or the flexible plastic fabric on the one hand and the film on the other. A thickness between 0.5 mm and 0.7 mm, in particular 0.6 mm, is particularly suitable for the permanent magnetic film.
    The fastening means preferably comprises one side of a Velcro fastener for a form fit with an adhesive force in the range from 0.5 N / cm 2 to 1 N / cm 2. The Velcro fastener also enables a very suitable structure of the warning mark.
    Preferably, the fastening means has sections which differ from one another with regard to their maximum adhesive force. A section that has a lower maximum adhesive force than another section peels off earlier. As a result, the peeling process begins in a definable area of the warning marking. Such a warning marking on the one hand prevents unwanted detachment due to inflation at the points with full adhesive force and enables a desired detachment at the points with reduced adhesive force even with smaller opening angles of the platform. As a result, the warning marking is adapted on the one hand to the rear geometry of the vehicle and the resulting turbulence, and on the other hand, the warning marking is peeled off starting at the points with reduced adhesive force.
    A weight, in particular between 90 g and 110 g, in particular 100 g, is preferably arranged on the warning marking, in particular in an area of reduced maximum adhesive force. This additional weight facilitates the desired peeling in defined areas.
    The warning marking preferably has a surface on which the fastening means is arranged, the fastening means being arranged only in a partial area of the surface. In this way, the full adhesive force can be achieved at the points that are critical with regard to undesired detachment due to inflation, for example on the lateral edges of the warning marking, without impairing the desired detachment.
    Preferably, the warning marking has an in particular rectangular surface, the fastening means comprising at least two parts which are arranged on the surface, in particular mirror-symmetrically to a plane of symmetry which is arranged perpendicular to the surface. This represents a particularly favorable design for warning markings, since these parts can be manufactured particularly efficiently.
    Preferably, the warning marker comprises a surface with a portion for permanent attachment to the platform, wherein the attachment means on the surface extends at least outside the portion for the permanent attachment and tapers towards the portion for the permanent attachment. Additional fastening is not absolutely necessary in the section in which the warning mark is permanently held.
    A tail lift has a platform, the platform being pivotable at least between a vertical and a horizontal pivot position with respect to the motor vehicle, and a fastening means for permanent magnetic adhesion or for adhesion by form-fitting or by adhesion of such a warning mark to the platform an adhesive force that is sufficient for the adherence of at least part of the warning marking in at least one pivot position of the platform different from the vertical pivoting position, the fastening means being designed such that the adherence of the portion of the warning marking is effected by a weight of the warning marking without manual loosening of the Adhesion and is detachable without energy supply in at least one other pivoting position of the platform different from the vertical pivoting position. In this way, the safety effect is achieved in all swivel positions without the need for energy or intervention by the driver.
    Preferably, the fastening means is arranged on the platform and designed so that the warning marking is at least partially detached when a pivot angle of the platform relative to the vertical pivot direction is less than or equal to 25 °. With such an arrangement, the effect of the warning marking is achieved particularly well.
    Preferably, the fastening means is designed to be permanent magnet at least in sections, the warning marking comprising ferritic material at least in a section of the warning marking that is complementary to the fastening means. It is more advantageous to attach the ferritic film to the warning marking, since it can be easily replaced when worn, regardless of a magnet on the platform.
    The fastening means is preferably of ferritic design, at least in sections, a permanent magnetic film being arranged on the warning marking at least in a section of the warning marking which is complementary to the fastening means. This makes it possible to keep the warning markings on platforms of different materials safely.
    The fastening means preferably comprises one side of a Velcro fastener, a side of the Velcro fastener that is complementary thereto being arranged on the warning marker at least in a section of the warning marker that is complementary to the fastening means. This makes it possible to hold the warning marking securely in the vertical pivoting position and to achieve a desired peeling if the use of ferritic or permanent magnetic material is undesirable or not permitted.
    The fastening means is preferably designed for an adhesive force in the range from 0.5 N / cm 2 to 1 N / cm 2. For a reliable detachment of the warning marking from the platform, a larger weight component has to be applied to overcome this adhesive force when the platform is lowered. This can be shown particularly well by a warning marking made of layers that comprise a tarpaulin material or a flexible plastic fabric. A thickness between 0.5 mm and 0.7 mm, in particular 0.6 mm, is particularly suitable for the permanent magnetic film.
    Preferably, the fastening means has sections which differ from one another with regard to their maximum adhesive force. This makes it easier to peel off the warning mark in the sections with reduced adhesive force.
    The platform preferably has a surface on which the fastening means is arranged, the fastening means being arranged only in a partial area of the surface. This makes it easier to peel off the warning marking in the sections in which no fastening means are provided.
    The platform preferably has an in particular rectangular surface, the fastening means comprising at least two parts which are arranged on the surface, in particular mirror-symmetrical to a plane of symmetry which is arranged perpendicular to the surface. This makes it possible to manufacture the fastening means particularly inexpensively.
    Preferably, the platform comprises a surface with a portion for permanent attachment of the warning mark to the platform, the attachment means on the surface extending at least outside of the portion for the permanent attachment and tapers towards the portion for the permanent attachment. No fasteners are required in the permanent fastening section. This enables material savings.

    FIG. 1 shows schematic parts of a warning marking 100 in a side view. The warning marking 100 comprises a carrier 102, which in the example comprises a tarpaulin material or a flexible plastic fabric. In the example, a reflective or retroreflective surface 104, in particular striped red and white, is arranged on the carrier 102. In the example, the surface 104 extends flat, in particular in a rectangular shape with dimensions of 250 mm × 400 mm. In the example, the carrier 102 extends on one of its sides, in particular in a rectangular manner, beyond the surface 104. In the example, the carrier 102 comprises on this side an in particular rectangular first section 106 of the warning marking 100, to which the warning marking 100 can be permanently attached. A fastening means 110 is arranged on a rear side of the carrier 102 at least in a second section 108 different from the first section 106. In the example, the second section 108 extends in a rectangular manner on the rear side of the carrier 102. The geometry and dimensions of the warning marking 100 can also be selected differently, for example depending on legal regulations.
    In FIG. 2, a side view of a holder 202 for permanent attachment of the warning marker 100 to a platform 204 is shown. The platform 204 is arranged on a tail lift 206, for example. In the example, the tail lift can be arranged at the rear of a motor vehicle. The example shows a platform that can be stowed vertically at a rear end of a truck. It can be a foldable platform that can be stowed horizontally under a truck. The warning marking 100 can be permanently attached to the holder 202 on the platform 204. The holder 202 can also deploy.
    FIG. 3 shows a schematic representation of parts of the tail lift 206 with the warning mark 100 in a horizontal pivoting position of the tail lift 206. The representation of FIG. 3 is a view from behind of the platform 204 of a tail lift 206 arranged at the rear of the motor vehicle.
    The warning marking 100 is arranged in the example so that it acts at least to the rear with respect to the motor vehicle both in the vertical pivot position and in the horizontal pivot position.
    If the warning marker 100 comprises a foldable platform which can be folded up and stowed horizontally, it can be provided that the platform comprises a pivotable part or the pivotable part is that from a horizontal pivoted position in which the platform can be stowed via a vertical pivot position is unfolded into a horizontal pivot position. In this case, the warning marking is arranged on one side of the pivotable part of the platform such that the warning marking acts to the rear when it is unfolded, at least from the vertical pivoting position.
    Figure 4 shows a schematic representation of a side view of parts of the tail lift 206 with the warning mark 100. Figure 4 shows the warning mark 100 in a first pivot position of the platform 204 different from the vertical pivot position and from the horizontal pivot position at a first point in time the warning mark 100 peels off. The warning marker 100 is permanently attached to the platform 204 with the holder 202. The warning marking 100 is still in contact with the platform 204 in a first area 402. In the first area 402, the holding force is sufficient for the warning marking 100 to adhere to the platform 204. The warning marking 100 is not in contact with the platform 204 in a second area 404 Platform 204. The contact does not have to be established directly with the platform 204 itself, but can, for example, via an intermediate layer arranged on the platform 204, such as, for example an advertising slide.
    FIG. 5 shows a schematic representation of parts of the tail lift with the warning marking 100 in the same pivoting position of the platform 204 at a second point in time, which is after the first point in time. The warning marking 100 is peeled off at the second point in time and is only attached to the platform 204 with the holder 202. The warning marking 100 is no longer in contact with the platform 204. The holder 202 can be designed such that the warning marking 100 is only in contact with the platform 204 in the area in which the holder 202 places the warning marking 100 on the platform 204 attached.
    The platform 204 of the tail lift 206 can be raised and lowered by a lifting and pivoting mechanism. The platform 204 can thus be pivoted at least between a vertical and a horizontal pivot position with respect to the motor vehicle.
    At least one warning marker 100 is arranged on the platform 204 so that the warning marker 100 acts to the rear with respect to the motor vehicle. In principle, such warning markings 100 can also be arranged in such a way that they act laterally or diagonally with respect to the motor vehicle in a pivot position different from the vertical pivot position.
    [0043] In one aspect, the fastening means 110 is designed to be permanently magnetic at least in sections. In one aspect illustrated in Figures 2, 4 and 5, the platform 204 comprises ferromagnetic material. In this aspect, a magnetic adhesive force generated by the fastening means 110 has an attractive effect in the vicinity of the platform 204 and keeps the warning marking 100 in contact with the platform 204 at least in the vertical pivoting position. When moving from the vertical pivoting position towards the horizontal pivoting position, gravity acts on the warning marking 100. The warning marking 100 is limp. The weight of the warning marking 100 and the adhesive force caused by the permanently magnetically designed fastening means 110 are coordinated with one another in such a way that the warning marking 100 is reliably detached, as shown in FIGS. 4 and 5 for two exemplary points in time. For example, the maximum adhesive force of the fastening means 110 and the dead weight of the warning marking 100 are selected such that the dead weight causes a weight force component perpendicular to a joining surface between the fastening means 110 and the platform 204, which is sufficient from a certain pivoting angle to overcome the maximum adhesive force. when the platform is moved from the vertical pivot position towards the horizontal pivot position.
    FIG. 6 shows another aspect in which a fastening means 602 is arranged on the platform 204. This fastening means 602 comprises, for example, a ferritic film arranged in the area of the warning marking 100. The platform 204 need not be ferromagnetic in this aspect. For example, a platform 204 made of aluminum is used.
    Instead of the permanent magnetic means described, or in addition to this, the fastening means 110 can also comprise one side of a Velcro fastener. In this aspect, a complementary side of the Velcro fastener is arranged on the platform 204 as a fastening means 602. The Velcro fastener is an example of a form-fitting adhesion with which the same effect can be achieved.
    In the example, the fastening means 110 and the fastening means 602 preferably together have an adhesive force in the range from 0.5 N / cm 2 to 1 N / cm, regardless of whether they are permanent magnetic, form-fitting or adhesive means 2> on. This adhesive force is particularly well suited for warning markings 100 that are designed in accordance with German road traffic regulations.
    FIG. 7 schematically shows further aspects of such a warning marking 100 in a rear view.
    The warning marking 100 has the first section 106, which can be fastened by the holder 202 to the platform 204 of the tail lift. The holder 202 can hold the warning marking 110 in the shape of a welt.
    The warning marking 100 has the fastening means 110 at least in the second section 108 of the warning marking 100 which is different from the first section 106. The fastening means 110 is designed to interact with the platform 204 or with the further fastening means 602 arranged on the platform 204, the warning marking 100 at least in a pivoting position different from the vertical pivoting position of the platform 204 with respect to the motor vehicle, at least in sections, by an adhesive force on the platform 204 adheres.
    In the example, the warning marking 110 is rectangular. The warning marking 100 has a rectangular area in the example. Other geometric shapes, for example a triangular surface, are also possible. The fastening means 110 is arranged flat on the surface of the warning marking 110, at least in the second section 108. In one aspect, the fastening means 110 is only arranged in a partial area of the surface. The fastening means 110 can also be arranged over the entire surface.
    In the example, the fastening means 110 comprises two parts which are arranged on the surface. Several parts can also be provided. The two parts in the example are mirror-symmetrical to a plane of symmetry that is perpendicular to the surface.
    In one aspect in which the surface includes the first portion 106 for permanent attachment to the platform 204, the fastener 110 is disposed on the surface at least outside of the first portion 106 and tapers toward the first portion 106.
    In the example, the fastening means 110 comprises a first permanent magnetic film 702 and a second permanent magnetic film 704. The first film 702 is designed as a five-sided straight prism in the example. In the example, the second film 704 is designed symmetrically to it as a five-sided straight prism. Deviations from the exactly symmetrical shape can also be provided.
    FIG. 8 shows a schematic representation of parts of a differently shaped fastening means 800 which can be arranged on the platform 204 or on the warning marking. In the example, this fastening means 800 is H-shaped and has two separate identical parts 802. Regardless of the specific shape, this fastening means 800 is permanently magnetic or ferritic or designed as one side of a Velcro fastener.
    FIG. 9 shows a schematic representation of an arrangement of the parts 802 for this fastening means 800. These parts 802 can be produced, for example, from a sheet-like raw material in a particularly material-saving manner, since the outer contours can be produced from the raw material with little waste. The fastening means described can also be designed in one piece.
    With regard to the area of the warning marking 100, the effective area on which the fastening means described is arranged is reduced due to the outer contours of the geometric shape. Instead of changing the effective area, it can be provided that a degree of magnetization or adhesion of the fastening means 110 is designed to be decreasing. Instead of using the holder 202, the magnetization in the first section 106 can be selected to be so strong that the warning marking 100 cannot become detached there by its own weight, regardless of the pivot position.
    In addition, a weight 706 can be provided in the second section 108 of the warning marking 110, in particular on a side of the second section 110 facing away from the first section 106. The weight 706 in the example is between 90g and 110g. The weight is preferably 100 g. The weight 706 can be designed like the holder 202. In particular, the weight 706 can receive the warning marking 110 in the form of a welt or be attached to the warning marking 110 as a strip.
    The weight 706 can itself be designed to be permanent magnet. In this case, the additional magnetic adhesive force contributed by the weight 706 is also taken into account in the design of the other parameters of the warning marking 100.
    In one aspect it can be provided that the fastening means 110 or the further fastening means 602 is arranged and designed on the platform 204 so that the warning marking 100 is at least partially detached when the pivot angle of the platform 204 relative to the vertical pivot direction is less than or is equal to 25 °.
    In one aspect, the fastening means 602 is designed to be permanently magnetic at least in sections, the warning marking 100 comprising ferritic material at least in a section of the platform 204 that is complementary to the fastening means 602.
    In one aspect, the fastening means 602 is at least partially ferritic. In this aspect, a permanently magnetic film is arranged on the warning marking 100 at least in a section of the warning marking 100 that is complementary to the fastening means 602.
    In one aspect, the fastening means 602 is a side of a Velcro fastener, a side of the Velcro fastener being arranged on the warning marking 100 at least in a section of the warning marking 100 that is complementary to the fastening means 110.
    In one aspect, the fastening means 602 has sections which differ from one another with regard to their maximum adhesive force.
    In one aspect, the platform 204 has a surface on which the fastener 602 is disposed. In this aspect, the fastening means 602 is only arranged in a partial area of the surface.
    It can be provided to arrange the fastening means 110 or the further fastening means 602 on the side of the second section 110 facing away from the first section 106, that a section without fastening means is arranged between the fastening means and the holder 202. When pivoting out of the vertical pivoting position, the warning marking 100 in this case causes a pulling force on the cable which also acts on the fastening means and facilitates peeling off in this area.
    In this way, the adhesion is released without manually releasing the adhesion and without a supply of energy, in particular without an energy supply that influences the adhesive force itself.
