Abstract

A spirit level with electrical illumination enables measurements to be made in situations where external illumination is inadequate. The two bubbles are each provided with an internal light source which may consist of a small bulb or light emitting diode. Alternatively, the light source may consist of a single small bulb (12) or light emitting diode. In this case the light is passed to the two bubbles via optical fibres (14,15). The spirit level also contains batteries (10,11) of suitable size and shape and a push button switch (13) or other suitable built-in switching device. The light source or sources may be integrated directly into the spirit level by being sealed in. The light sources need only be illuminated under adverse light conditions.

Description

ELEKTRISCH BELEUCHTETE WASSERWAAGE Die Erfindung betrifft eine Wasserwaage, die elektrisch beleuchtet ist. ELECTRICALLY LIGHTED SPIRIT LEVEL The invention relates to a spirit level, which is electrically illuminated.

Mit Hilfe einer solchen Wasserwaage ist es möglich, bei unzulänglicher Außenbeleuchtung Messungen durchzuführen.With the help of such a spirit level it is possible in case of inadequate Perform outdoor lighting measurements.

Es ist bekannt, daß Wasserwaagen als Hilfsgerät des Bauhandwerkers oder Heimwerkers zum Bestimmen der waagrechten bzw. senkrechten Lage von Kanten und Flächen verwendet werden. Dabei handelt es sich um Stücke aus Hartholz oder Leichtmetall mit parallel abgerichteten Kanten und zwei Ausfräsungen, in die je ein an beiden Enden verschlossenes, mit Ether oder Alkohol gefülltes Glasröhrchen (Libelle) so eingesetzt ist, daß beim Einspielen eines auf der Flüssigkeit schwimmenden Luftbläschens zwischen zwei Markierungen die Kanten der Wasserwaage genau waagerecht bzw. senkrecht verlaufen. It is known that spirit levels are used as an auxiliary device for the builder or do-it-yourselfer to determine the horizontal or vertical position of edges and surfaces are used. These are pieces of hardwood or Light metal with parallel, trimmed edges and two cutouts in each a glass tube closed at both ends and filled with ether or alcohol (Dragonfly) is inserted so that when you import a floating on the liquid Air bubbles between two marks, the edges of the spirit level are exactly horizontal or run vertically.

Die Libellen lassen sich nur bei guten Lichtverhältnissen ablesen.The dragonflies can only be read in good lighting conditions.

Es schien daher wünschenswert, eine Wasserwaage zu entwickeln, die frei von diesem Mangel ist. It therefore seemed desirable to develop a spirit level that is free from this deficiency.

Die Aufgabe wird erfindungsgemäß durch Einbau einer elektrischen Beleuchtung in die Wasserwaage gelöst. Dazu gehört eine interne Stromversorgung aus einer Batterie sowie ein Oruck45chalter (Ein-Aus). Nach Betätigung des Schalters werden die Libellen von einer Lichtquelle angestrahlt und können dann auch bei schwachem Außenlicht mühelos abgelesen werden.The object is achieved according to the invention by installing electrical lighting dissolved in the spirit level. This includes an internal power supply from a battery as well as an Oruck45chalter (on-off). After pressing the switch, the vials are illuminated by a light source and can then also be used in weak outside light can be read effortlessly.

Ausführungsbeispiele der Erfindung werden anhand der schematischen Zeichnung näher erläutert.Embodiments of the invention are based on the schematic Drawing explained in more detail.

Fig. 1 In eine handelsübliche Wasserwaage 1 (aus Teakholz, Aluminium usw.) werden zwei parallelgeschaltete Lämpchen (3,5 V, 0,2 A) 2 und 3 so eingebaut, daß sie auf die beiden Libellen 4 und 5 strahlen. Die Stromversorgung der beiden Birnchen erfolgt durch zwei in einem ebenfalls eingebauten Batteriekasten untergebrachten Monozellen (je 1,5 V) 6 und 7. Der Stromkreis wird durch den Druckschalter 8 geschlossen.Fig. 1 In a commercially available spirit level 1 (made of teak, aluminum etc.) two parallel-connected lamps (3.5 V, 0.2 A) 2 and 3 are installed in such a way that that they shine on the two dragonflies 4 and 5. The power supply for the two Bulbs are made by two housed in a built-in battery box Mono cells (1.5 V each) 6 and 7. The circuit is closed by the pressure switch 8.

Fig. 2 In eine handelsübliche Wasserwaage 9 (aus Teakholz, Aluminium usw.) wird unmittelbar an zwei eingebaute Monozellen (je 1,5 V) 10 und 11 ein Birnchen (3,5 V, 0,2 A) 12 intern angebracht.Fig. 2 In a commercially available spirit level 9 (made of teak, aluminum etc.) a bulb is attached directly to two built-in mono cells (1.5 V each) 10 and 11 (3.5 V, 0.2 A) 12 attached internally.

Das Lämpchen wird mittels des Druckschalters 13 eingeschaltet.The lamp is switched on by means of the pressure switch 13.

Das Licht wird über zwei Glasfasern ( 3 mm) 14 und 15 zu den Libellen 15 und 17 geleitet.The light is sent to the dragonflies via two glass fibers (3 mm) 14 and 15 15 and 17.

Eine so modifizierte, mit Beleuchtung ausgerüstete Wasserwaage hat sich seit einem Jahr im praktischen Betrieb bestens bewährt.Has such a modified spirit level equipped with lighting has proven itself in practical operation for a year.
