Description

Many different spirit levels from different manufacturers are offered on the market for home and craft tools. These spirit levels have different features, ranging from one spirit level vial to three vials to a laser beam. There are also other versions of spirit levels on the market, e.g. in tripods for photo equipment.

This application was based on the task of developing a spirit level for spirit levels }

to develop a level that replaces the three conventional spirit levels ( 0, 45 and *

90 degrees ) as a component to produce an inexpensive spirit level {

Furthermore, the new spirit level should also be able to be installed in hand drills as an optical positioning aid.

The task is solved by placing a liquid (11) in a transparent ball ('10), similar to the "artificial horizon" indicator in an airplane. On the liquid of this new spirit level there is a float (12), in whose

A rod (13) is attached at right angles to the center. On the spherical shell are \

Circular paths in 0.45 and 90 degree positions are applied in the maximum circle diameter, so that a spatial coordinate system is created.

If the scale or hand drill is tilted slightly, the float and rod will visibly move out of the coordinates. However, they can be quickly brought back into alignment with a slight correction.

Figure 1a shows the transparent sphere (10) in which the liquid (11) is located. The liquid (11) carries the float (12), to which the rod (13) is attached in the middle at right angles to the float. The spatial coordinate system is applied to the sphere shell as circular orbits in 0, 45 and 90 degrees.

Figure 1 b shows the bearing from a horizontal position. The system is vertical, so the float (12) and rod (13) are exactly in the coordinate system (14).

Figure 1c shows a bearing from a vertical position. The image shown is when taking a bearing from above and below. The system is also vertical here, so that the rod (13) is in a point-like position and the float (12) is in a circle in the coordinate system (14).

Figure 2 shows the installation of the transparent vial ball (10) in a spirit level.

Figure 3 shows the installation of the transparent spirit level ball (10) in the handle of a hand drill.

Claims (4)

Klaus Rebbe Bodelschwinghweg 19 -1 - 68305 Mannheim Three-dimensional spirit level bubble CLAIMS 1. A three-dimensional spirit level vial characterized by the fact that a float is located in a transparent ball half filled with liquid, which is located exactly in the abscissa axis of the ball and in the middle of which a rod is attached at right angles, which is located exactly in the ordinate axis of the ball and which, when viewed vertically from above and below, can be seen as a point. 2. Three-dimensionally indicating spirit level according to claim 1, characterized in that circular paths in 0, 45 and 90 degree positions are applied to the spherical shell, each at the maximum sphere diameter, which form a spatial coordinate system. 3. Three-dimensionally indicating spirit level vial according to claims 1 and 2, characterized in that when used in a spirit level it replaces the three conventional spirit level vials (O ₁ 45 and 90 degrees). 4. Three-dimensionally indicating spirit level according to one of the preceding claims, characterized in that, due to its possible small size, it can be used in the handle of a hand drill as an optical positioning aid for axially correct drilling in any drilling direction.
