Abstract: A laser device, including a cradle with a laser unit exiting from this, the cradle being connected to a base element, relative to which the cradle can be adjusted in terms of inclination by at least one actuating drive. In order to achieve a secure mounting of the cradle for the laser unit with simple structural means, while at the same time eliminating any play between the mutually tilting parts, it is proposed that the cradle be connected to the base element, first, by a solid joint, and secondly by two adjusting drives, wherein the adjusting drives are arranged with respect to the solid joint so that the lines of connection between lengthwise axis of the solid joint and the adjusting drives subtend a right angle.

Abstract: The invention concerns a spirit level (10) including a base body (11), e.g., in the form of a hollow profile, as well as a bubble level vial (12), formed of a vial body (14) with enclosed cavity (16), preferably of barrel shape, the vial being secured in the base body by means of a holder (28). The cavity contains a liquid (18) with gas bubble (20) floating therein and the vial body has end face regions (32, 36) running transversely to the lengthwise axis of the cavity. In order to achieve a high contrast between the end of the bubble and the liquid, it is proposed that the vial body (14) be joined to the holder (28) by an intimate material connection in the at least one end face region (32, 36) and that the holder and/or the intimate material connection be contrast intensifying in the region of the at least one end face region.

Abstract: The invention relates to a spirit level comprising a spirit level body (10) which is made from a spray-injected thermoplastic material with at least one recess (22) for a spirit level. In order to embody the spirit level body (10) such that it is long but without drawing said body, a reinforcing insert (32) made of fiber-reinforced plastic is injected around inside the spirit level body (10).

Abstract: An arrangement for depicting a linear optical marking on a surface, including a radiation source emitting light, such as laser radiation, as well as a first lens arranged in the beam path having a first and a second surface penetrated by the radiation, of which one surface features a parabolic or elliptical trace at least partially in cross section, formed of curved sections of different radii, the trace extending symmetrically with respect to a plane of symmetry of the lens, along which runs the beam directed in parallel, preferably by means of a second lens. In order to achieve a uniform power distribution along the line, it is proposed that the first surface formed of sections with different radii faces the radiation.

Abstract: A measuring apparatus including a measuring device, such as a laser measuring device with a housing, which is detachably connected to a tripod including a tripod head and emanating therefrom tripod legs which are height-adjustable and can pivot on swivel or pivot joints and which are formed of telescoping inner and outer tubes which can be fixed in a desired position in relation to one another by means of a locking element such as a union nut. At least two of the tripod legs can be put together to form a height-adjustable, clampable supporting rod extending between two boundaries spaced apart from one another.

Abstract: A laser device with a housing which features a beam outlet window (24), particularly a laser device with an electro-optical mechanism for generating a horizontal and/or vertical light beam, where the housing is at least partially enclosed by a protective covering (10). In order to provide secure protection for the beam outlet window without significantly altering the outer dimensions of the housing when the device is not in use, it is proposed that the protective covering (10) be pivotable about an axis that passes through the housing, and that it feature a first section which, depending on the pivot position of the protective covering, covers or exposes the beam outlet window (24).

Abstract: A protective device made of plastic, which is intended as an instrument housing for a measuring instrument. In order to ensure sufficient shock protection, which assures that the protective device is not damaged by hard shocks, the protective device is assembled from a core which is made of thermoplastic material and at least in sections encloses the housing, and a sheathing, which is made particularly of rubber elastic material.

Abstract: The invention concerns a device for projecting a linear optical marking onto at least one boundary of a room, such as floor surface for example, comprising a light source (12) that emits laser radiation along an optical axis (16) as well as a cuboid lens (14) connected in series with the light source, penetrated by the optical axis and reflecting as well as refracting the radiation. To facilitate fanning and reflecting of light originating from the light source through constructively simple means, the invention proposes that provided in the frontal surface (20) is a channel-shaped depression (40) and provided in the rear surface (22) is a projection (24), both of which are geometrically designed and arranged so that the radiation can be totally reflected and that totally reflected radiation striking the depression can be fanned out, where the optical marking runs to both transverse surfaces of the lens.

Abstract: A laser measuring device (50) including a housing (56) with a laser device present therein for generating and projecting at least one laser beam (52, 54), perpendicular to an alignment surface (34) of the housing, or to a mount (14) that is connected to the housing. In order to enable an exceedingly precise alignment of a laser beam to the center point of an opening in a room boundary, such as the floor, without requiring costly adjustment operations, it is proposed that the alignment surface (34) be equipped with at least three synchronously adjustable positioning elements, which lie in a circle, through the center point of which the laser beam (54), which extends perpendicular to the alignment surface (34), or its extension, passes.
