Abstract

The invention relates to a method for the reversible marking of points of impact which is characterised in that a heat-sensitive substance is used which changes colour owing to the conversion of kinetic energy into thermal energy in the event of impact by solid bodies. The method according to the invention is advantageously used to mark pitches for ball games, tennis courts, machine part impact points and the like.

Description

Die Erfindung betrifft ein Verfahren zur reversiblen Markierung von Impaktstellen.The invention relates to a Process for the reversible labeling of Impact points.

Es ist im Sport, beispielsweise beim Tennis, oft ein Problem, auf Teppichböden, Estrich, Asphalt, Grasnarbe, Kies oder dergleichen, den Auftreffpunkt, die Im­ paktstelle, eines Balles korrekt zu bestimmen.It's in sports, like tennis, often a problem on carpets, screed, Asphalt, turf, gravel or the like, the point of impact, the Im paktstelle to correctly determine a ball.

Dadurch ist es unmöglich, festzustellen, ob ein Ball im Aus getroffen war oder noch "gut" war.This makes it impossible to determine whether a Ball was hit in the out or was still "good".

Dieses Problem tritt auch in Hallen auf, wo ebenfalls der beispielsweise auf Sandplätzen wichtige Ball-Abdruck fehlt.This problem also occurs in halls where also that, for example, on clay courts important ball imprint is missing.

Es besteht somit Bedarf an einer Methode, den Auftreffpunkt von Bällen zu markieren, wobei diese Markierung nach kurzer Zeit wieder ver­ schwinden soll, um Verwechslungen mit späteren Auftreffern zu vermeiden.There is therefore a need for a method that Mark the point of impact of balls, whereby Ver this mark again after a short time should disappear to avoid confusion with later ones Avoid hits.

Diese Aufgabe wird erfindungsgemäß dadurch ge­ löst, daß eine thermosensitive Substanz verwendet wird.This object is thereby ge solves that a thermosensitive substance is used.

Besondere Ausführungsformen der Erfindung sind dadurch gekennzeichnet,
daß die thermosensitive Substanz durch die beim Aufprall fester Körper aus kinetischer Energie entstehende thermische Energie zur Farbänderung angeregt wird,
daß die thermosensitive Substanz unter Energie­ abgabe in den (farblosen) Grundzustand zurück­ kehrt,
daß als thermosensitive Substanz eine Verbindung mit mindestens zwei, gegebenenfalls konjugierten Doppel­ bindungen und/oder gegebenenfalls einem ladungsbe­ hafteten π-Elektronensystem, die mindestens ein Heteroatom mindestens einer Heteroatomart enthält, und zur Aufnahme thermischer und/oder Schockwellen­ und/oder elektromagnetischer Energie sowie zur Wieder-Ab­ gabe elektromagnetischer Strahlung im sichtbaren Bereich geeignet ist, verwendet wird,
daß eine thermosensitive Substanz, gegebenenfalls als Lösung in einem flüchtigen Lösungsmittel, im zu über­ wachenden Bereich aufgebracht wird.Particular embodiments of the invention are characterized in that
that the thermosensitive substance is stimulated to change color by the thermal energy arising from kinetic energy when solid bodies impact,
that the thermosensitive substance returns to the (colorless) ground state while releasing energy,
that as a thermosensitive substance a compound with at least two, optionally conjugated double bonds and / or optionally a charge-adhering π- electron system, which contains at least one heteroatom of at least one type of heteroatom, and for the absorption of thermal and / or shock waves and / or electromagnetic energy and for re-use -If electromagnetic radiation is suitable in the visible range is used,
that a thermosensitive substance, optionally as a solution in a volatile solvent, is applied in the area to be monitored.

Beansprucht wird weiterhin die Verwendung des erfin­ dungsgemäßen Verfahrens zur Markierung von Ballspiel- Plätzen, Tennis-Courts, Maschinenteil-Auftreffpunkten und dergleichen.The use of the inventor is still claimed method according to the invention for marking ball game Courts, tennis courts, machine-part impact points and the same.

Das Verfahren gemäß vorliegender Erfindung gestattet es mit sprunghaft gestiegener Präzision, auch ver­ glichen mit Ballabdrücken auf Sandplätzen, die Auf­ treffstelle von Bällen bei Ballspielen für einen kurzen Zeitraum präzise zu erkennen.The method according to the present invention allows it with leaps and bounds of precision, also ver equalized with ballprints on clay courts meeting point of balls at ball games for one short period of time.

Die Flüchtigkeit der Markierung vermeidet Verwirrungen und überwindet weitgehend die Verwechslungsgefahr beim Auftreffen mehrerer Bälle innerhalb eines kurzen Zeitraums hintereinander. The volatility of the marker avoids confusion and largely overcomes the risk of confusion when hitting multiple balls within a short one Period in a row.  

Die Aufbringung der erfindungsgemäß verwendeten Substanz ist beispielsweise durch Sprühen mit einer Sprühdose, durch Aufstreichen mit einem Pinsel oder dergleichen möglich. Dabei ist die Substanz in der Regel in einem geeigneten flüchtigen, umweltfreundlichen Lösungsmittel oder Lösungsmittelgemisch gelöst. Es ist auch möglich die Substanz in Pulverform, gegebenfalls gemischt mit inerten Füllstoffen, und/oder die Adsorptions- bzw. Emmisions-Wellenlänge verschiebenden Substanzen aufzutragen, zu verstreuen oder zu versprühen.The application of those used according to the invention Substance is, for example, by spraying with a Aerosol can, by brushing or the like possible. The substance is in the Usually in a suitable volatile, environmentally friendly Solvent or solvent mixture dissolved. It is also possible to use the substance in powder form, optionally mixed with inert fillers, and / or the adsorption or emission wavelength apply shifting substances, scatter or to spray.

Das Verfahren zur reversiblen Markierung von Impakt­ stellen findet auch Anwendung im industriellen Bereich. So gestattet die reversible Markierung beispielsweise die präzise Beobachtung der Auftreff- bzw. Zusammen­ treffstelle von Maschinenteilen, Kolben, Kugel und dergleichen. Aufgrund der Farbigkeit der Auftreff- bzw. Berührungsstelle ist darüberhinaus eine Filmkontrolle entsprechender Vorgänge möglich.The process for reversibly marking impact places are also used in the industrial sector. For example, the reversible marking allows the precise observation of the impact or together where machine parts, pistons, balls and the like. Due to the color of the impact or The point of contact is also a film inspection corresponding operations possible.

Demzufolge findet das erfindungsgemäße Verfahren vor­ teilhafterweise Anwendung in Maschinenbau, Gerätebau, Fahrzeugbau und dergleichen.Accordingly, the method according to the invention is found partly used in mechanical engineering, device construction, Vehicle construction and the like.
