The preparation of technical drawings is facilitated and accelerated in such a way that rounding off instead of using a compass with a template. This is set in such a way that the corresponding rounding

/ is tangent to the two straight lines to be connected. Stencils that are used to draw such roundings are has already been proposed in principle by the applicant himself. However, to ensure that the drawings are correct, i.e. accordingly to be able to implement the standards is in accordance with the present ! • Price increases a special design of such a template

ne revealed. Accordingly, the new essentially consists in that the curves are carried out according to DIN 250, whereby the curves of the Yorzug row with larger or underlined Numbers or other? ^ Ra marked

If the purpose of the template ^{T is} to increase further, provision is made that, in addition to the few small radii, also larger radii in full circular form are cut out of the template area, so that the template can also be used for the border x ^r on numbers and letters can be used. Details can be found in the following description and the drawing. The latter represents an embodiment in plan view.

According to Din 250, the curves a are different Diameters provided, namely the radii of the preferred rows specially marked, which is indicated by larger numbers, underlining, frames, raised markings, etc. can happen. The previously customary very small curves d are recessed in full circular shape. G-raäss the innovation there are also larger roundings b in full circular form recessed so that there are also borders for letters and numbers can be carried out in different sizes without the aid of a compass. The spacing warts c for ink drawing According to the innovation, they are advantageously attached to the writing side, so that when drawing with pencil the stencil lies flat against the drawing surface ^ can; when drawing in ink with the well-known funnel pen or the like. the template is turned over so that the necessary distance between the drawing surface and the template is ensured ν? £ 3? 3τ is.

Claims (3)

Protection claims 1.) Rounding template, characterized in that the Roundings (a) are designed according to DIW 250, the roundings the preferred series with ^ larger or underlined Numbers or in any other form are identified. 2.) Rounding template according to claim 1, characterized by dadur-eh, that apart from very small radii (d) also larger ones Radii (b) (e.g. r - 3 to 8 mm) are recessed in full circular form, so that the template is also used for the border, from Numbers and letters can be used. 3.) Rounding template «after speeches 1-2, marked through the arrangement of elevations (Ab & tandsv / arzen c) the purpose ::; usually provided on the upper (written) side are, so the inverted template advantageous for the use of funnel springs in the manufacture of Indian ink drawings can be used.
