Die Erfindung betrifft ein Meßgerät zur Messung sehr kleiner Meßwege mit einem aus mehreren hintereinandergeschalteten mech^mschenJHebeln mit_ekjstP schem~TJeienk bestehenden Hebelgetriebe zum Übertragen" der Meßbewegungen.The invention relates to a measuring device for measuring very small measuring paths with a lever mechanism consisting of several n mechanical levers connected one behind the other with a mechanical lever mechanism for transmitting the measuring movements.
Meßgeräte für kleine Meßlängen bis 5 mm mit einem mechanischen Hebel und elastischem Gelenk sind bekannt. Die mit diesen Geräten erzielba-re Meßgenauigkeit ist jedoch infolge der ungünstigen mechanischen Übersetzung in vielen Fällen nicht ausreichend, so daß noch optische Mittel angeordnet werden müssen. Dadurch werden die Geräte kompliziert und teuer. Ferner wird dadurch die Bauhöhe der Geräte unvorteilhaft vergrößert. Ferner sind Meßgeräte für sehr kleine Meßlängen unter 2 mm bekannt, bei denen zwischen dem mechanischen Hebel und den optischen Mitteln zusätzlich Doppelkreuzfedergelenke als Zwischenübersetzungsmittel eingeschaltet sind, wodurch die kleinen Verstellwege spielfrei vergrößert und auf den am Mittelteil eines Doppelkreuzfedergelenkes sitzenden Drehspiegel übertragen werden. Derartige Anordnungen erfordern jedoch infolge der Vielzahl der empfindlichen und komplizierten Teile eine schwierige und zeitraubende Montage und Justierung. Weiterhin sind zur Messung sehr kleiner Meßwege elektrische, photoelektrische und pneumatische Geräte bekannt, die jedoch neben einer kostspieligen Gebereinrichtung auch noch eine gesonderte Anzeigeapparatur erfordern, wodurch der ganze Aufbau des Gerätes, seine Handhabung und Herstellung nachteilig beeinflußt sind. Alle diese Geräte sind überdies in den meisten Fällen nur für ganz bestimmte Meßzwecke ausgebildet und gestatten ohne kostspieligen Umbau keine universale Anwendung für mehrere verschiedenartige Meßaufgaben.Measuring devices for small measuring lengths up to 5 mm with a mechanical lever and elastic joint are known. The measurement accuracy achievable with these devices is, however, due to the unfavorable mechanical In many cases, the translation is not sufficient, so that optical means are still arranged have to. This makes the devices complicated and expensive. This also increases the overall height of the devices unfavorably enlarged. Furthermore, measuring devices for very small measuring lengths below 2 mm are known at those between the mechanical lever and the optical means additionally have double cross spring joints are switched on as intermediate translation means, whereby the small adjustment paths are enlarged and free of play can be transferred to the rotating mirror located on the middle part of a double cross spring joint. Such However, due to the multitude of delicate and complicated parts, arrangements require one difficult and time-consuming assembly and adjustment. Furthermore, very small measuring paths are used for measuring electrical, photoelectric and pneumatic devices known, but in addition to an expensive transmitter device also require a separate display device, whereby the entire structure of the device, its handling and manufacture are adversely affected. All of these devices are also in the In most cases they are only designed for very specific measuring purposes and do not require expensive modifications no universal application for several different measuring tasks.

Die Erfindung ist an Hand der Zeichnung an einem schematisch dargestellten Ausführungsbeispiel erläutert. The invention is explained with reference to the drawing using a schematically illustrated embodiment.
Mit 1, 2, 3 und 4 sind hintereinandergeschaltete, spielfrei miteinander verbundene Hebel bezeichnet, die als ein einheitliches, leicht und billig herstellbares Stanzteil gefertigt sind, so daß die gelenkigen Verbindungsstellen aus dünnen elastischen Stegen 5, 6, 7, 8, 9 und 10 bestehen. Der durch eine Blattfeder 11 geführte kurze Hebel 1 dient als Tastorgan, während das Abtriebshebelglied 4 für eine direkte Ablesung des Meßweges als Zeiger ausgebildet ist. Infolge der großen Übersetzung der !mechanischen Hebel 1 bis 4 und der spielfreien, von keiner Reibung beeinflußten elastischen Verbindungsstellen 5 bis 10 gestattet ein derartiges Meßgerät die Ausführung sehr genauer direkter Messungen. Es kann als Feintaster für die Messung von sehr kleinen Längen und Dehnungen sowie als Oberflächen-Tastprüfgerät und zur Dickenmessung feinster Folien und für ähnliche MeBaufgaben angewendet werden. 1, 2, 3 and 4 are consecutively connected levers that are connected to one another without play and are manufactured as a uniform, easily and cheaply produced stamped part, so that the articulated connection points are made of thin elastic webs 5, 6, 7, 8, 9 and 10 exist. The short lever 1 guided by a leaf spring 11 serves as a feeler element, while the output lever element 4 is designed as a pointer for direct reading of the measuring path. As a result of the large translation of the mechanical levers 1 to 4 and the backlash-free, elastic connection points 5 to 10 which are not influenced by any friction, such a measuring device enables very precise direct measurements to be carried out. It can be used as a fine probe for the measurement of very small lengths and strains as well as a surface probe tester and for measuring the thickness of the finest foils and for similar measuring tasks.
