Abstract: A spirit level has a hollow profile member as the spirit level body and at least one bubble level with a bubble level holder. The bubble level holder is mounted moveably in the spirit level body, and the bubble level holder has an opening into which a fixing element can be introduced through a wall of the spirit level body. The fixing elements prevents a displacement of the bubble level holder parallel to the longitudinal axis of the spirit level body, and allows a movement of the bubble level holder normal to a measurement surface of the spirit level body.

Abstract: A level device for a spirit level includes a level device body, and a substantially cylindrical cavity formed by an inside wall of the level device body. The cavity has a longitudinal axis and serves to accommodate a liquid, and the level device body is arranged in a carrier body. The carrier body includes two transparent covers for closing the carrier body and preferably includes a casing body which is preferably in the form of a circular ring. An outside wall of the level device body has a curved region with a curvature in the longitudinal direction relative to the longitudinal axis of the cavity, by which a magnifying glass effect can be achieved when viewing a marker body which can be arranged in the cavity.

Abstract: A device includes a vial for a spirit level. The vial has at least a first and a second region, and the second region directly adjoins the first region. A marker body is provided in the vial, and the marker body in a leveled condition of the vial is disposed in the first region. One of the at least two regions is darkened and thereby the marker body is partially visible outside the leveled condition of the vial.

Abstract: A spirit level includes a profile body having a recess, a vial disposed in the recess of the profile body, and an evening-out part. A step is formed between the vial and the profile body on a side face of the profile body, and the evening-out part covers the step and spans the recess of the profile body. The evening-out part is flush with the side face of the profile body, and may have a magnifier effect.

Abstract: Spirit level with at least one vial disposed in a recess of a profile body of the spirit level, which [vial] is optionally provided with a cover, wherein between the vial or the cover and the profile body on at least one side face of the profile body a step is formed, wherein an evening-out part is provided which evens out the step between the vial, or the vial with cover, and the profile body to all bordering side faces of the profile body.

Abstract: An airlessly sealed vial includes an interior cavity filled with at least one liquid. At least one sealing cap is provided, which seals closed an opening into the interior cavity. The vial also includes means associated with the sealing cap and/or the interior cavity for changing the volumetric liquid containing capacity of the interior cavity in accordance with volumetric changes in the liquid contained in the vial. The means may be a moveable or flexible wall at least partly defining the interior cavity and/or a compressible member included in the interior cavity.

Abstract: A level has a level body made of a hollow profiled section having a bottom wall whose underside forms a measuring surface and further having a top wall and sidewalls, the sidewalls connecting the bottom wall and the top wall. The level body has a window opening for receiving a horizontal vial for horizontal measurement. A securing device for mounting the horizontal vial within the level body is provided. The securing device has a vial holder, in which the horizontal vial is secured, and at least one clamping part that is movable relative to the vial holder for clamping the securing device in the level body. In the mounted state of the securing device, the at least one clamping part is supported on an inner side of the top wall and the vial holder is pressed against an inner side of the bottom wall.

Abstract: A cross laser device for installing plate- or board-shaped floor covering elements on a flat substrate includes a housing which can be positioned on the substrate by feet, and at least one first and one second laser disposed within the housing, by which first and second laser beams emerging through first and second front light exits of the housing can be generated for the formation of first and second marking lines on the substrate, which marking lines intersect at right angles at an intersection point spaced apart from the light exits. An underside of the housing is spaced apart from the substrate such that first and second clearance zones beneath the housing extend continuously from first and second side edges of the housing up to first and second vertical planes, respectively, the first and second laser beams being located in the first and second vertical planes, respectively.
