Definitions

  • the present invention relates to a safety pivot compass for drawing circular arcs or complete circles on a support, this compass comprising two branches articulated at their common ends, one arm being equipped with a safety pivot and the other a pencil or pencil holder.
  • the present invention relates to a compass equipped with a safety pin to avoid the drawbacks mentioned above while ensuring the stability and accuracy of the plot.
  • Mister 60MEZ BARQUERO (FR-A- 1 323 435), soft to facilitate the drawing of circles on the blackboard - such as the inventions of Messrs CHR1STY (US-A-2 074 102) and ZWEIFEL (CH - A - 360 507), either again in order to spare the support as proposed by the invention of
  • the safety pivot compass designed in particular for the safety of the user, brings the following innovations:
  • the present invention retains compass the ergonomic properties of the instrument such that it is currently designed, manufactured and distributed in the public.
  • the invention relates to a compass of the type indicated in the preamble, characterized in that said safety pivot has a rounded end situated at the end of an axis housed in a body and in that said rounded end is partially or entirely covered with a non-slip surface intended to be in contact with said support to define the center of the circle or the arc of a circle to be drawn.
  • the rounded end is partially or entirely spherical. Said rounded end can be movable about its axis, relative to the fixed body of said pivot.
  • the arms of the compass are made in two articulated parts and the two lower parts are connected to a return mechanism arranged to position them along an axis perpendicular to said support.
  • FIG. 1 shows an elevational view of a compass according to the invention
  • FIG. 2 is an enlarged sectional view of the safety pivot object of the invention.
  • the compass (1) consists of two branches (2) and (3), articulated at their common ends in (4). Each branch is terminated by an articulated part (2 ') and (3').
  • a return mechanism here consisting of a rod (10), keeps the lower parts of each branch (2 ') and (3') in a position perpendicular to the support whatever the angle of opening of the compass.
  • One of the branches is equipped with a safety pivot (5) and the other, a mechanical pencil or pencil holder (6).
  • the pivot comprises a fixed body (9) receiving a movable axis (8), itself terminated by a spherical point (7) covered with a non-slip surface (7 ').
  • the present invention is not limited to the embodiment described above; but extends to any variant or modification obvious to those skilled in the art.
  • the safety pivot as described can be adapted to any other drawing instrument rotating around an axis.
