Abstract

The device comprises a spherical element (1) with a prismatic surface reflector at the front to be inserted into the heel area of the shoe (1.9). The sphere (1) is attached to the lower end of a stick serving as a handle and fitted with a laser generator. A spring loaded telescopic bar is attached to the lower side of the sphere (1), leading to the front of the shoe and used for keeping the shoe in a stretched-out position. The laser beam (1.10) is reflected by the inner surface at the front of the shoe, the result transmitted (12) to a computer (11) and converted into millimeters.

Description

Es ist bekannt, dass der Innenraum von Schuhen, wenn überhaupt, mittels mechanischen Messhilfen wie Lineale zu vermessen. Die genauen Innenmaße von Schuhen sind jedoch für die exakte Größenermittlung und dem genauen Anpassen an den menschlichen Fuß, überaus wichtig. Die von den Herstellern ausgezeichneten Schuhmodelle entsprechen weder einem Standart noch sind sie genau. Die zusätzlich, durch den Herstellungsprozess entstehenden maßlichen Tolerenzen und damit die abweichenden Größenangaben erschweren den Anpassprozess beim Schuhkauf im Fachhandel oder ähnlichem damit ganz erheblich.It is known that the interior of shoes, if any, using mechanical measuring aids such as rulers to measure. The exact inside dimensions of shoes are however for the exact size determination and the exact adaptation to the human foot, very important. The from the manufacturers excellent shoe models are neither standard nor they are exactly. The additional, through the manufacturing process resulting dimensional tolerances and thus the different sizes complicate the fitting process when buying shoes in stores or similar with it quite considerably.

Der Erfindung liegt die Aufgabe zu Grunde, diese vorhandenen Mängel bei der Vermessung des Innenraums von Schuhen zu beheben und somit eine genaue genormte Zuordnung der Schuhgrößen zu erreichen.Of the Invention is based on the object of these existing deficiencies the measurement of the interior of shoes to fix and thus an accurate standardized assignment of shoe sizes to achieve.

Die Aufgabe wurde wie folgt gelöst:
Um menschliche Messfehler weitest gehend auszuschließen, wird die Messung durch den Einsatz von Laserstrahlen vorgenommen.The task was solved as follows:
In order to exclude human measurement errors as far as possible, the measurement is made by the use of laser beams.

Der Lasersensor kann sich genau in der Längsachse des Mess-Strahles befinden oder um besser mit dem Messgerät in den Innenraum von Schuhen kommen zu können, durch ein Oberflächenverspiegeltes Prisma das in einem Winkel von ca. 80–95 Grad zur Längsachse des Mess-Strahles am Messgerät angebracht ist, vorgenommen werden.Of the Laser sensor can be exactly in the longitudinal axis of the measuring beam or better with the meter in the interior of shoes to be able to come through a surface mirrored Prism that at an angle of about 80-95 degrees to the longitudinal axis of the measuring beam on the measuring device appropriate to be made.

Dabei ist es sehr wichtig, dass das Messgerät zum einen exakt im ausgebuchteten Bereich der Schuhferse und zum anderen an der längsten Stelle der Schuhspitze positioniert wird. Dazu ist das Messgerät so konstruiert das es diesen Anforderungen genüge leistet. Die Kugel 1.8, die zum einen die Aufnahme des Oberflächenverspiegeltes Prismas sowie den Haltestab 1.7 und den sich selbst anpassenden Grundkörper 1.2 gewährleistet rastet durch ihre Formgebung genau in der Kugelferse der Schuhe ein. Der spezielle Aufsatz 1.3 an der vorderen Spitze des Messgerätes 1 presst das Material des Schuhes zusammen und spannt es gleichzeitig in Längsrichtung, das ist von größter Wichtigkeit wie nur so eine genaue Längsmessung möglich ist. Im Anschluss wird die Lasermessung ausgelöst in dem der Lasersensor den Laserstrahl über den Spiegel (Oberflächenverspiegeltes Prisma) ad die zu vermessende Stelle des Schuhes (Schuhspitze) sendet. Die durch die Zurücksendung des Laserstrahles an das Lasermessgerät übertragenen Daten werden in ein Millimetermaß umgewandelt, dieses wird entweder im Lasermessgerät selbst oder in einen mit Kabel oder Infrarotschnittstelle verbundenen Computer in Schuhgrößen (EU, UK, US, MP) umgerechnet und am Bildschirm angezeigt bezw. in ein speziell dafür vorgesehenes Computerprogramm eingelesen und können dann weiterverarbeitet werden.It is very important that the measuring device is positioned on the one hand exactly in the notched area of the heel of the shoe and on the other hand on the longest point of the toe. For this purpose, the measuring device is designed so that it meets these requirements. The ball 1.8 , on the one hand, the recording of the surface-mirrored prism and the retaining bar 1.7 and the self-adjusting body 1.2 guaranteed by its shape snaps exactly in the ball heel of the shoes. The special attachment 1.3 at the front tip of the meter 1 squeezes the material of the shoe together and simultaneously strains it in the longitudinal direction, which is of the utmost importance as only such an accurate longitudinal measurement is possible. Subsequently, the laser measurement is triggered in which the laser sensor sends the laser beam over the mirror (surface-mirrored prism) ad to the point to be measured of the shoe (shoe tip). The transmitted by the return of the laser beam to the laser measuring device data are converted to a millimeter measure, this is converted either in the laser measuring device itself or in a computer connected with cable or infrared interface computer in shoe sizes (EU, UK, US, MP) and displayed on the screen BEZW. read into a specially designed computer program and can then be further processed.

Durch eine spezielle Anordnung des Oberflächenverspiegeltes Prismas im Schuh selbst, können auch andere Werte wie zum Beispiel die Breite des Schuhes ermittelt werden.By a special arrangement of the surface mirrored prism in the Shoe yourself, too other values such as the width of the shoe can be determined.
