Abstract

The movement and position detector contains a sphere (4, 6) with an electrically conducting surface. The sphere always adopts a position on a system carrier (1, 5) dictated by equilibrium of the forces acting upon it. The spehre short circuits conducting paths (3) on the system carrier, the paths having different potentials, as it rolls over them. The deformation of the paths is evaluated by a circuit to determine the magnitudes and directions of the forces acting on the sphere for further signal processing. USE/ADVANTAGE - Detection of forces and their directions in three-dimentional space. The forces acting on a sphere are measured using a simple mechanical arrangement requiring minimal space.

Description

Die Erfindung betrifft einen Bewegungs- und Lagedetektor zur Erfassung von Kräften bezüglich ihrer Stärke und Richtung, welche auf einen Körper einwirken.The invention relates to a movement and position detector for Detection of forces regarding their strength and direction, which act on a body.

Bekannte Detektoren benötigen dazu eine aufwendige Mechanik mit entsprechender Störanfälligkeit.Known detectors also require complex mechanics corresponding susceptibility to failure.

Der Erfindung liegt die Aufgabe zugrunde, mit einfachen mechani schen Mitteln unter minimaler Raumforderung eine Krafteinwirkung auf eine Kugel (4, 6, 11, 13) und deren Richtung festzustellen.The invention has for its object to determine a simple mechanical means with minimal space requirements force on a ball ( 4 , 6 , 11 , 13 ) and their direction.

Auf dem Systemträger (1, 5, 8, 12) befinden sich elektrisch leitende Bahnen, auf welchem eine Kugel (4, 6, 11, 13) mit elektrisch leitender Oberfläche rollt und durch einen Kugelkäfig (2, 7, 9, 14) umschlossen wird. Der Systemträger kann eine zur Kugel hin ebene (Bild 1) oder gewölbte (Bild 2) oder unterschied lich strukturierte, je nach den zu messenden Ereignissen und auslösenden Situationen entsprechend beschaffene Form besitzen. Die Konfiguration der elektrisch leitenden Bahnen (3, 10) und die Form des Kugelkäfigs (2, 7, 9, 14) wird bestimmt durch die Anforderungen an den Detektor bezüglich der Art und der Ansprech empfindlichkeit und Genauigkeit der Messung. Die elektrisch leitenden Bahnen können ein wechselweise unterschiedliches elek trisches Potential besitzen, welches durch die darüberrollende Kugel kurzgeschlossen wird. Eine Positionsänderung der Kugel (4, 6, 11, 13) in Bezug zu dem Systemträger (1, 5, 8, 12) durch Krafteinwirkung auf dieselbe vermittels Magnetismus, Gravitation, Zentrifugalkraft oder eine Lageänderung des Systemträgers gegen über der Kugel kann somit durch Öffnen und Schließen entsprechen der Abschnitte der elektrisch leitenden Bahnen (3, 10) in Quantität und Qualität durch eine nachgeschaltete elektronische Auswertung registriert werden.There are electrically conductive tracks on the system carrier ( 1 , 5 , 8 , 12 ), on which a ball ( 4 , 6 , 11 , 13 ) with an electrically conductive surface rolls and is enclosed by a ball cage ( 2 , 7 , 9 , 14 ) becomes. The system carrier can have a shape that is level with the sphere ( Fig. 1) or curved ( Fig. 2) or structured differently, depending on the events to be measured and the triggering situations. The configuration of the electrically conductive tracks ( 3 , 10 ) and the shape of the ball cage ( 2 , 7 , 9 , 14 ) is determined by the requirements placed on the detector with regard to the type and response sensitivity and accuracy of the measurement. The electrically conductive tracks can have an alternately different electrical potential, which is short-circuited by the ball rolling over them. A change in position of the ball ( 4 , 6 , 11 , 13 ) in relation to the system carrier ( 1 , 5 , 8 , 12 ) by applying force to it by means of magnetism, gravitation, centrifugal force or a change in position of the system carrier relative to the ball can thus be opened and closing correspond to the sections of the electrically conductive tracks ( 3 , 10 ) in quantity and quality are registered by a subsequent electronic evaluation.

Claims

Movement and position detector for the electronic detection of forces and their direction in three-dimensional space, characterized in that a ball with an electrically conductive surface ( 4 , 6 , 11 , 13 ) on a system carrier provided with electrically conductive tracks ( 3 , 10 ) 1 , 5 , 8 , 12 ) with any shape determined by the type of measurement, always takes the position that results from the balancing of the forces acting on the ball. As a result, different electrical potentials of adjacent conductive tracks of the system carrier are short-circuited through the electrically conductive surface of the ball by the ball rolling over the conductive tracks when the position changes. Due to the shape of the electrically conductive tracks, a downstream electronic evaluation can deduce the magnitude of this force acting on the ball and its direction and make the result accessible for further processing.
