In all cases, the distance is determined by measuring the transit time of a pulse emitted by the handheld device, which is reflected on the appropriate object and is received again by the handheld device.
Bei einem bekannten, handgehaltenen Entfernungsmeßgerät (DE 196 52 438 C2) ist ein linienförmiger Meßanschlag von der Längskante der spitzwinklig zulaufenden Rückseite des Gehäuses gebildet, wobei der Übergangsbereich von der Gehäuseober- und -unterfläche zu der Längskante geradlinig oder bogenförmig gekrümmt ist. Der mittlere Teil dieser Längskante, einschließlich des zugehörigen Übergangsbereichs zur Gehäuseober- und -unterfläche, ist um eine zur Meßrichtung parallele Drehachse drehbar ausgebildet, so daß er um einen beliebigen Drehwinkel gegenüber den beiden äußeren, feststehenden Teile der Längskante verdreht werden kann. Fluchten der mittlere und die beiden äußeren Teile der Längskante miteinander, so kann das Entfemungsmeßgerät rückseitig mit dieser Längskante, beispielsweise mit einer von zwei "Wänden gebildeten Eckenlinie, in Anschlag gebracht werden und so beispielsweise die Diagonale eines Raums gemessen werden. Da die Längskante in der Bezugsebene für die Entfemungs- oder Abstandsmessung liegt, ist der vom Entfemungsmeßgerät im Display angezeigte Wert die tatsächliche Entfernung der Eckenlinie zum angemessenen Objekt, beispielsweise zu der diagonal gegenüberliegenden Eckenlinie des Raums. Soll andererseits das Entfemungsmeßgerät für Messungen von objektzugewandten Flächen, wie z.B. Wände, Decken, Böden, aus verwendet werden, so ist der mittlere Bereich der Längskante, einschließlich des zugehörigen Übergangsbereichs um einen beliebigen Drehwinkel, z.B. um ca. 90°, zu drehen. Da die Drehachse parallel zur Meßrichtung ausgerichtet ist, befinden sich die um den Drehwinkel gegeneinander verdrehten Teile der Längskante stets in einer senkrechten Ebene zu der Meßlichtung. Somit ist die Meßrichtung stabil im rechten Winkel zu einer ebenen Anlagefläche ausgerichtet, und es wird die Entfernung von der Anschlagfläche zu dem angemessenen Objekt bestimmt. Das vom Entfemungsmeßgerät angezeigte Ergebnis entspricht exakt der Entfernung bzw. dem Abstand der gewählten Anschlagfläche zu dem angemessenen Objekt, ohne daß es einer Umrechnung oder einer Umschaltung im'Entfernungsmeßgerät bedarf.In a known, hand-held distance measuring device (DE 196 52 438 C2), a linear measuring stop is formed from the longitudinal edge of the rear side of the housing tapering at an acute angle, the transition region from the upper and lower surfaces of the housing to the longitudinal edge being curved in a straight line or in an arc. The middle part of this longitudinal edge, including the associated transition area to the housing upper and lower surfaces, is designed to be rotatable about an axis of rotation parallel to the measuring direction, so that it can be rotated by an arbitrary angle of rotation relative to the two outer, fixed parts of the longitudinal edge. If the middle and the two outer parts of the longitudinal edge are aligned with one another, the distance measuring device can be brought into abutment with this longitudinal edge on the back, for example with a corner line formed by two " walls, and thus, for example, the diagonal of a room can be measured. Since the longitudinal edge in the The reference plane for the distance or distance measurement lies, the value indicated by the distance measuring device in the display is the actual distance of the corner line to the appropriate object, for example to the diagonally opposite one Corner line of the room. If, on the other hand, the distance measuring device is to be used for measurements from surfaces facing objects, such as walls, ceilings, floors, the central area of the longitudinal edge, including the associated transition area, must be rotated by any angle of rotation, eg by approximately 90 °. Since the axis of rotation is aligned parallel to the direction of measurement, the parts of the longitudinal edge which are rotated relative to one another by the angle of rotation are always in a plane perpendicular to the measurement clearing. Thus, the measuring direction is stably oriented at right angles to a flat contact surface, and the distance from the stop surface to the appropriate object is determined. The displayed result from Entfemungsmeßgerät corresponds exactly to the distance or the distance of the selected abutment surface adequate to the object without the need for a conversion or a change in the 'distance measuring.
Bei einem ebenfalls bekannten Entfemungsmeßgerät (DE 198 04 051 AI) ist auf den linienförmigen Meßanschlag zur Anlage an einer Referenzlinie, z. B. die Eckenlinie zwischen zwei Wänden, verzichtet, und ein flächiger Meßanschlag ist auf der ebenen Rückwand des Gehäuses ausgebildet. Für den Fall, daß ausgehend von einer Außenkante gemessen werden soll, die Anlagekante für das Entfemungsmeßgerät also von dem anzumessenden Objekt abgewandt ist, ist ein weiterer Anschlag vorgesehen, der auf der Innenseite einer am Gehäuse schwenkbar gelagerten Schwenkldappe ausgebildet ist. Die Schwenlddappe ist bei Nichtgebrauch des weiteren Meßanschlags auf die Unterseite des Gehäuses aufgeklappt und kann zur Aktivierung des weiteren Meßanschlags um 90° vom Gehäuse abgeschwenkt werden. In dieser Schwenkstellung der Schwenklappe ist der weiteren Meßanschlag dem anzumessenden Objekt zugewandt und liegt in der Bezugsebene für die Entfernungsmessung, so daß nach Anlegen des weiteren Meßanschlags an die Außenkante und Auslösen des Meßvorgangs der im Display angezeigte Entfernungswert der tatsächliche Abstand des angemessenen Objekts von der Anlegekante ist. Vorteile der ErfindungIn a also known distance measuring device (DE 198 04 051 AI) is on the linear measuring stop for contact with a reference line, for. B. the corner line between two walls, waived, and a flat measuring stop is formed on the flat rear wall of the housing. In the event that measurements are to be taken starting from an outer edge, that is to say the contact edge for the distance measuring device is facing away from the object to be measured, a further stop is provided which is formed on the inside of a swivel flap which is pivotably mounted on the housing. When the additional measuring stop is not in use, the Schwenlddappe is opened onto the underside of the housing and can be swiveled 90 ° away from the housing to activate the further measuring stop. In this swivel position of the swivel flap, the further measuring stop faces the object to be measured and lies in the reference plane for the distance measurement, so that after the further measuring stop has been placed on the outer edge and the measuring process has been triggered, the distance value shown on the display shows the actual distance of the appropriate object from the contact edge is.

Gemäß einer vorteilhaften Ausführungsform der Erfindung weist der Schwenlckeil eine Grundstellung, die so festgelegt ist, daß der zweite Meßanschlag in der Bezugsebene liegt, und eine Einschwenkstellung auf, in welcher er vollständig in das Gehäuse eingeschwenkt ist. In der Grundstellung ist der Schwenkkeil am Gehäuse lösbar verriegelt. Durch diese Festlegung der Grundstellung des Schwenkkeils ist das Handgerät für die Hauptanwendung, nämlich die Distanzmessung von einer dem anzumessenden Objekt zugekehrten Anlagefläche aus, permanent eingestellt. Für die anderen Meßaufgaben muß der jeweils benötigte Meßanschlag nur noch durch einen einzigen Handgriff aktiviert werden, nämlich durch Abschwenken der Schwenkklappe von dem in seiner Grundstellung sich befindlichen Schwenlckeil zum Aktivieren des dritten Meßanschlags und durch Einschwenken des in seiner Grundstellung sich befindlichen Schwenkkeils in das Gehäuse zum Aktivieren des ersten Meßanschlags.According to an advantageous embodiment of the invention, the pivoting wedge has a basic position, which is determined such that the second measuring stop lies in the reference plane, and a pivoting-in position, in which it is pivoted completely into the housing. In the basic position, the swivel wedge is on Detachably locked housing. This definition of the basic position of the swivel wedge means that the hand-held device is permanently set for the main application, namely the distance measurement from a contact surface facing the object to be measured. For the other measuring tasks, the measuring stop required in each case only has to be activated by a single handle, namely by pivoting the pivoting flap away from the pivoting wedge in its basic position to activate the third measuring stop and by pivoting the pivoting wedge in its basic position into the housing Activate the first measurement stop.
