Problems solved by technology

[0007] A disadvantage of the previously known pull-out or telescopic spirit levels is that the mutually displaceable structural elements, that is to say the base body and the pull-out element, come into contact with each other during the displacement, so that especially in the event of dust or dirt May not give the desired flexibility when depositing in areas where the structural elements are supposed to slide on top of each other (Leichtgängigkeit)

Embodiment Construction

[0049] The characteristic features of the extendable or extendable or telescopic spirit level 10 according to the invention are shown in the figures (where in principle identical elements are marked with the same reference numerals), said features being referred in particular to Image 6 , 7 and 11-13 are self-explanatory and require no further elaboration.

[0050] The spirit level 10 consists of a base body 12 which, in the exemplary embodiment, can be a section of a four-sided hollow profile made of aluminum. The pull-out element 14 is longitudinally displaceable relative to the base body 12 in order to vary the measuring length of the spirit level 10 within a desired range. The pull-out element 14 can likewise be a profiled segment of aluminum whose geometry can be derived from Figure 11 Known self-evidently.

[0051] Furthermore, a spirit level present in the housing 16 is arranged in the base body 12 in a customary manner in order to achieve its alignment with respec...

Abstract

The invention relates to a spirit level (10) comprising a base body (12) with a first measuring base (52) and a A pull-out element (14) displaceable in the longitudinal direction of the base body, wherein the first measuring base and the second measuring base extend at the same level. In order to achieve a low-friction displacement setting, a first sliding element ( 26 ) proceeds from the base body ( 12 ), said first sliding element cooperating locally with a positive fit with the pull-out element ( 14 ) and for The pull-out element is loaded with a force in or approximately along the normal direction of the measuring base (52, 54), and a second sliding element (28) proceeds from the pull-out element, which locally forms a positive fit with the The base bodies cooperate and act on the pull-out element with a force in or approximately in the direction normal to the measuring base.

Description

technical field [0001] The invention relates to a spirit level comprising a base body with a first measuring base and a pulley connected to the base body and displaceable relative to the base body in the longitudinal direction of the base body with a second measuring base. Out of the element, wherein the first measurement bottom and the second measurement bottom extend at the same level. Background technique [0002] A corresponding pull-out or retractable spirit level makes it possible to carry out an orientation over a length which extends beyond the base body or base body. The pull-out element used for this purpose can be a profile element displaceable in the base body, which has a cross-section in cross-section, as specified in DE 196 05 868 A1. A similar design is found in DE 200 22 165 U1. The H profile is used instead of the cross profile. [0003] According to US 2 419 451 A a variable-length spirit level provides that the base body or base body and the pull-out e...
