Stand der TechnikState of the art
Die Erfindung betrifft eine Entfernungsmessvorrichtung, insbesondere eine Laserentfernungsmessvorrichtung, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a distance measuring device, in particular a laser distance measuring device, according to the preamble of claim 1.
Bei bekannten Entfernungsmessvorrichtungen umfassen die Mittel zur Entfernungsmessung eine Sendeeinheit und eine Empfangseinheit, wobei von der Sendeeinheit ein Messsignal in Richtung eines Objektes, zu dem die Entfernung bestimmt werden soll, ausgesendet wird. Das an dem Objekt reflektierte Messsignal wird von der Empfangseinheit empfangen, wobei eine Auswerteelektronik, beispielsweise durch eine Laufzeitmessung oder interferometrische Methoden die Ent- fernung zu dem Objekt bestimmt. Es ist bekannt, als Messsignal Laserlicht, Ultraschallwellen oder Radarwellen einzusetzen .In known distance measuring devices, the means for measuring the distance comprise a transmitting unit and a receiving unit, wherein a measuring signal is emitted by the transmitting unit in the direction of an object to which the distance is to be determined. The measuring signal reflected on the object is received by the receiving unit, with evaluation electronics determining the distance to the object, for example by means of transit time measurement or interferometric methods. It is known to use laser light, ultrasonic waves or radar waves as the measurement signal.
Insbesondere um die Messung zu starten oder bestimmte Ein- gaben zu tätigen, weisen bekannte Entfernungsmessvorrichtungen, als Drucktasten ausgebildete Bedienmittel auf. Ferner sind bekannte Entfernungsmessvorrichtungen mit als Display ausgebildeten Anzeigemitteln ausgestattet, um das Messergebnis und/oder über die Bedienmittel getätigte Ein- gaben anzuzeigen. Die Anzeigemittel sowie die Bedienmittel befinden sich in der Regel auf einer Oberseite der Entfernungsmessvorrichtung, die im Wesentlichen rechtwinklig zu einer Stirnseite der Entfernungsmessvorrichtung angeordnet ist, aus der das Messsignal austritt und in der das Messsignal empfangen wird. Da bekannte Entfernungsmessvorrichtungen häufig an stark verschmutzten Orten, insbesondere auf Baustellen, eingesetzt werden, kommt es oft zu einer Verschmutzung und/oder Beschädigung der Anzeigemittel und/oder der Bedienmittel, was wiederum zu einer verkürzten Lebensdauer der Entfernungsmessvorrichtung führt.In particular, in order to start the measurement or to make certain inputs, known distance measuring devices have operating means designed as pushbuttons. Furthermore, known distance measuring devices are provided with display means designed as display in order to display the measurement result and / or inputs made via the operating means. The display means and the operating means are usually located on an upper side of the distance measuring device, which is arranged substantially at right angles to an end face of the distance measuring device is, from which the measuring signal emerges and in which the measuring signal is received. Since known distance measuring devices are frequently used in heavily polluted locations, in particular on construction sites, soiling and / or damage of the display means and / or the operating means often results, which in turn leads to a shortened service life of the distance measuring device.
Offenbarung der Erfindung Technische AufgabeDISCLOSURE OF THE INVENTION Technical Problem
Der Erfindung liegt daher die Aufgabe zugrunde, eine Entfernungsmessvorrichtung vorzuschlagen, bei der die Gefahr einer Beschädigung und/oder Verschmutzung minimiert ist.The invention is therefore based on the object to propose a distance measuring device in which the risk of damage and / or contamination is minimized.
Technische LösungTechnical solution
Diese Aufgabe wird mit einer Entfernungsmessvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiter- bildungen der Erfindung sind in den Unteransprüchen angegeben. In den Rahmen der Erfindung fallen auch sämtliche Kombinationen aus zumindest zwei von in der Beschreibung, den Ansprüchen und/oder den Figuren angegebenen Merkmalen.This object is achieved with a distance measuring device having the features of claim 1. Advantageous developments of the invention are specified in the subclaims. All combinations of at least two features specified in the description, the claims and / or the figures also fall within the scope of the invention.
Der Erfindung liegt der Gedanke zugrunde, der Entfernungsmessvorrichtung einen Schutzdeckel zuzuordnen, mit der die ersten Anzeigemittel und/oder die ersten Bedienmittel, zumindest teilweise, abdeckbar, d. h. schützbar sind. Insbesondere dann, wenn die Entfernungsmessvorrichtung nicht in Gebrauch ist, können die ersten Anzeigemittel und/oder die ersten Bedienmittel mittels des mindestens einen Schutzdeckels zumindest teilweise, vorzugsweise vollständig, abgedeckt werden, sodass eine Verschmutzung der Anzeigemittel und/oder Bedienmittel, insbesondere ein Verkratzen eines Displays oder einer Bedientaste erschwert oder bevorzugt vermieden wird. Je nach Anordnung und/oder Ausbildung eines fakultativen Verstellmechanismus für den Schutzdeckel wird die Bedienbarkeit , insbesondere die Handhabbarkeit bzw. Griffigkeit von durch Miniaturisierungsbestrebungen immer kleiner werdenden Entfernungsmessvorrichtungen verbessert. Bei einer nach dem Konzept der Erfindung ausgebildeten Entfernungsmessvorrichtung muss der Schutzdeckel nicht aus- schließlich eine Schutzfunktion für die ersten Anzeigemittel und/oder die ersten Bedienmittel haben, sondern der Schutzdeckel selbst kann, wie später noch erläutert werden wird, als Träger für Bedienmittel und/oder Anzeigemittel dienen, insbesondere bei Entfernungsmessvorrichtungen, bei denen die Bedienmittel und/oder die Anzeigemittel ansonsten, aufgrund der Miniaturisierungsbestrebungen (Platzmangel) zu klein ausgebildet werden müssten.The invention is based on the idea of assigning the distance measuring device a protective cover, with which the first display means and / or the first operating means, at least partially, can be covered, ie, protected. In particular, when the distance measuring device is not in use, the first display means and / or the first operating means by means of the at least one protective cover at least partially, preferably completely covered so that contamination of the display means and / or operating means, in particular scratching a display or a control button difficult or preferably avoided. Depending on the arrangement and / or formation of an optional adjustment mechanism for the protective cover, the operability, in particular the handling or grip of miniaturization efforts ever smaller distance measuring devices is improved. In a distance measuring device designed according to the concept of the invention, the protective cover need not exclusively have a protective function for the first display means and / or the first operating means, but the protective cover itself can, as will be explained later, as a support for operating means and / or Display means serve, in particular in distance measuring devices, in which the operating means and / or the display means would otherwise have to be made too small due to the miniaturization efforts (lack of space).

Auf die zweiten Anzeigemittel 13 und die zweiten Bedienmittel 14 kann bei Bedarf auch verzichtet werden. Ebenso ist es denkbar die ersten Anzeigemittel 3 und/oder die ersten Bedienmittel 4 zumindest teilweise am Schutzdeckel, insbesondere an der Innenseite 12 des Schutzdeckels 9 anzu- ordnen.As can be seen from Fig. 1, are on an inner side 12 of the protective cover 9, which is opposite to the housing top 5 in the closed state, second display means 13 and second control means 14 are arranged so that the provided by the protective cover 9 surfaces in terms of the realization of optimum operability. If necessary, the second display means 13 and the second operating means 14 can also be dispensed with. Likewise, it is conceivable to arrange the first display means 3 and / or the first operating means 4 at least partially on the protective cover, in particular on the inner side 12 of the protective cover 9.
Wie aus Fig. 2 ersichtlich ist, befinden sich an der der Innenseite 12 gegenüberliegenden Außenseite 15 des Schutzdeckels 9 weitere, dritte Anzeigemittel 16, insbesondere zur Anzeige einer Datums- und/oder einer Uhrzeitinformation. Auf derartige dritte Anzeigemittel 16 kann bei Bedarf verzichtet werden. Das in den Fig. 1 und 2 gezeigte Ausführungsbeispiel kann dahingehend abgewandelt bzw. erweitert werden, dass durch einen fakultativ vorzusehenden Rastme- chanismus der Schutzdeckel 9 in definierten Winkelstellungen relativ zu dem Gehäuse 6 arretierbar ist, um somit den Schutzdeckel 9 als Hilfe bei der Ausrichtung der Entfernungsmessvorrichtung 1 einsetzen zu können.As can be seen from FIG. 2, on the inside 12 opposite outside 15 of the protective cover 9 there are further, third indicating means 16, in particular for displaying a date and / or a time information. On such third display means 16 can be omitted if necessary. The exemplary embodiment shown in FIGS. 1 and 2 can be modified or extended so that the protective cover 9 can be locked in defined angular positions relative to the housing 6 by means of a locking mechanism to be optionally provided, thus providing the protective cover 9 with assistance in alignment to use the distance measuring device 1 can.
In Fig. 3 ist ein weiteres Ausführungsbeispiel einer als Laserentfernungsmessvorrichtung ausgebildeten Entfernungsmessvorrichtung 1 gezeigt. Zu erkennen ist das Gehäuse 6 sowie der relativ zu dem Gehäuse 6 verschiebbar angeordnete Schutzdeckel 9, der in Pfeilrichtungen 17 zwischen einer Öffnungsstellung und einer Schließstellung verstellt werden kann, wobei der Schutzdeckel 9 in der Schließstellung die Gehäuseoberseite 5 mit den aus Fig. 3 nicht zu erkennenden ersten Anzeigemitteln und ersten Bedienmitteln vollständig abdeckt. Zusätzlich können bei Bedarf weitere verschiebbare oder verschwenkbare oder verrastbare Schutzdeckel vorgesehen werden.FIG. 3 shows a further exemplary embodiment of a distance measuring device 1 designed as a laser distance measuring device. Evident is the housing 6 and the relative to the housing 6 slidably disposed Protective cover 9, which can be adjusted in the arrow directions 17 between an open position and a closed position, wherein the protective cover 9 completely covers the housing top 5 in the closed position with the not visible from FIG. 3 first display means and first operating means. In addition, additional sliding or pivoting or latchable protective cover can be provided if necessary.
Alternativ zu der in den Fig. 1 und 2 gezeigten Verschwenk- lösung und der in Fig. 3 gezeugten Verschiebelösung können auch Rastmittel zum Verrasten des Schutzdeckels 9 am Gehäuse 6 vorgesehen werden. Damit ist es möglich, den Deckel durch Aufstecken und Verrasten am Gehäuse 6 festzulegen. As an alternative to the pivoting solution shown in FIGS. 1 and 2 and the displacement solution generated in FIG. 3, latching means for latching the protective cover 9 to the housing 6 can also be provided. This makes it possible to fix the lid by attaching and locking the housing 6.
