Device for determining the horizontal and vertical lines and for indicating the inclination of a surface from the horizontal using a gravity weight

The invention represents an alternative to the conventional spirit level. The display by spirit levels in the middle and on one side of the spirit level is replaced by a display device in the invention. This represents a great simplification compared to the spirit level and enables a more precise reading of the values to be determined for the horizontal and vertical lines as well as an exact angle measurement. Otherwise, the invention does not overlap with other inventions (P 27 26 486.4 + DE 28 39 + G 76 33 93^·9) which are based on similar tasks but are completely different in their implementation.

The display device consists of the rotor (4), the housing (1) and the liquid damping.

The rotor (4) consists of a closed flat cylinder (8), the axle bore (io), an axle (9), a gravity body (5)» the pressure compensation pad (6) and the nozzle (7). The closed cylinder (4, 8) consists of a light, non-transparent plastic with flow bores and a flat-sided axle bore (óó) through which a brass axle (9) is guided so that the cylinder (rotor) (4 _t 8) can carry out a gravity movement. In the rotor (4) itself there is a heavy metal weight (5}

The rotor is firmly supported and has two mounting holes (7). A flexible hose is guided onto this as a pressure compensation part (6). A total of twelve raised indicator plates (k) are attached to the housing (8); they are offset in positions γ - 3° to ⁹ °. The starting point is the TDC point. According to the laws of gravity, the rotor (k) rotates in any upright position due to the weight (5) so that the markings δ indicate the horizontal and vertical positions.

The housing (1) consists of a Plexiglas ring (2) and two glass disks ( '}) which are fitted laterally into the ring (2) to form a closed body in cylinder shape (1). Twelve marking pins (12), four on the Plexiglas ring inside and four each on the two glass disks (3) inside in the position γ - 36o, each offset by 90, are attached in such a way that when they correspond with the markings (13) on the rotor (k) the position is horizontal or vertical. In the center of the sliding disks (3) there is a hole (11) inside which serves to accommodate the rotor spindle (9). To dampen the pendulum movement of the rotor (k) , the rotor (k) and housing (1) are filled with a liquid, preferably commercially available antifreeze, until there is no air. This results in εγ. a predetermined breaking point (i3) at the filling and ventilation opening after closing.

For the main use, the display device is adjusted into a setting scale leg (14) and inserted in a shock-absorbing manner. The corresponding windows (16) in the leg allow readings from both sides in the finished setting scale leg (i4). To determine any angle, the device is integrated into an angle setter in a larger version than above and with fine graduations all around (360/5 ) on the housing (1). Adjustment and fastening in any stationary workpiece, regardless of material and size, with coarse or fine graduations depending on the area of application, is possible.
