Definitions

• the invention relates to a collapsible warning triangle for motor vehicles with three elongated edge strips made of plastic, the sides of the unfolded triangle being formed on the flat side with a preferably reflective signal color, at least one of them in both of them End regions by a hinge formed as a film hinge is each connected to one of the other edge strips, and to a base provided on the lower edge strip which forms the hypotensive element of the unfolded triangle, the edge strips connected by film hinges in each case at their ends are closed off by a straight mitred edge, the angle of which is included with the outer edge of the associated edge strip is approximately equal to half the angle of the angle which is included by the outer edges of two edge strips which meet when the warning triangle is unfolded.
• Warning triangles can be handled easily, quickly and safely. To save space, they should generally be foldable.
• a warning triangle of the type mentioned is known, the cathets of which are already connected in one piece to the hypotenuse via hinge sections, so that the warning triangle can be folded in a zigzag shape.
• special means must be provided that can be brought into engagement with the frame parts and hold the parts in their triangular shape. This can be, for example, locking pins or
• the catheters must be stably connectable. Especially in the case of using push buttons or locking pins, this means that it is often difficult to loosen this connection when the triangle is folded together.
• the invention is therefore based on the object of providing a legally compliant, easily manageable, foldable warning triangle for motor vehicles, which can be produced at significantly lower cost.
• this object is achieved according to the invention in that the edge strips all connect the miter edges that meet each other
• Film hinges are connected in an articulated manner, and that the edge strip forming the hypotenuse of the triangle in turn is centered by a separating cut running at right angles to its boundary edges in two edge lines which are in turn pivotally connected by at least one film hinge. half is divided.
• An advantage of the invention is that the production of the main component, ie the actual warning triangle, is possible as an integral part in the injection molding process, which eliminates the need to install the edge strips. Nevertheless, the warning triangle can be folded up to a small format in a simple manner, in that on the one hand the edge strip halves of the lower edge strip forming the hypotenuse are folded in the middle and at the same time the edge strips forming the cathets are pivoted along the film hinges.
• the edge strips halves of the lower edge strip can each be connected via a separate film hinge to an elongated base strip crossing the lower edge strip in the unfolded state at right angles, on the opposite flat sides of which the edge strip half can be folded when the triangle is folded up.
• This base can be designed so that it forms a base for the warning triangle and that an additional base can be dispensed with.
• it can also be designed as a shorter support strip and fastened on a separate, for example metallic, base crossing the hypotenuse of the unfolded triangle.
• This support bar then represents a connecting piece between the hypotenuse and the base.
• the support bar provided with latching means is locked on the stand in such a way that the unfolded warning triangle and the support bar come upright and perpendicular to one another on the stand.
• support feet are advantageously molded onto the outer ends of the edge strips forming the hypotenuse, which support the unfolded triangle at its outer corners.
• the pedestal is advantageously designed so that it extends in the direction of the edge strips of the folded warning triangle, so that the particularly compact shape of the collapsed warning triangle is retained when a separate pedestal is additionally provided.
• the base can consist of an elongated metal part, for example a straight hollow profile piece.
• the base is made of an elongated one Metal part, for example a flat steel, the end sections of which are bent in the direction away from the edge strips of the triangle, that is to say in the direction of the bottom.
• the height of these end sections is advantageously dimensioned such that it is equal to the height of the support feet molded onto the ends of the edge strip forming the hypotenuse of the triangle.
• the triangle is supported in a cross shape at four points on the ground.
• the support feet molded onto the hypotenuse can have recesses which laterally encompass the base in the folded state of the warning triangle.

• Randieist halves are connected to the marginal ridges forming the cathete by film hinges, but are otherwise separated from one another or the standing ridge by separating cuts.
• the edge strip halves of the edge strips can be folded back on themselves along their longitudinal central axis, as a result of which the warning triangle in the folded state has a width which is only equal to half the width of the edge strips in the opened state.
• the film hinges are each provided in the area of the flat sides of the edge strips connected to one another and / or the standing or support strips, which are folded onto one another when the triangle is folded together.
• edge strips divided into edge strip strips along their central longitudinal axis

• the edge strips are each subdivided into at least two edge strip strips with differently colored surfaces, of which at least one of the edge strip strips each has the prescribed reflecting signal color.
• the reflective edge strip strips additionally have fluorescent properties is particularly advantageous. This means that one is illuminated only briefly by the headlights of a passing motor vehicle or a traffic light
• Warning triangle remains on and can then fulfill its warning function even if it is not illuminated directly.
• the different coloring of the edge strip strips can be produced by spraying with correspondingly differently colored plastic starting materials in the two-color spraying process known per se.
• the edge strips can also be produced in a single color, in which case the different coloring of the edge strip strips is produced by subsequently applying a correspondingly colored coating.
• the subsequently applied colored coating can either be a set or hardened layer, for example a lacquer layer, applied in liquid or pasty form, or it is formed by a material strip applied to the respective edge strip.

• the course of the film hinges 20 is not placed exactly on the bisector of the angle, but instead is offset somewhat at an angle. Then, in order to unfold the triangle, a certain elastic deformation of the edge strips is additionally required, which the warning triangle first tries to fold back when unfolding, but then - as it unfolds slightly compared to the unfolded position - snaps over a dead center position, so to speak, and the warning triangle elastically in the unfolded position holds.
