Description

Technical field

BACKGROUND OF THE INVENTION The present invention relates to the construction of a multifunctional measuring instrument for the mechanical measurement of length, angles, perpendicularity or circle drawing and intended for use by carpenters, carpenters, glaziers, painters, bricklayers or other craftsmen, workshop or home maintenance work. .

BACKGROUND OF THE INVENTION

At present, various rulers, protractors, tibs, or multi-purpose jigs are used to measure the length, angle, or perpendicularity of surfaces, which allow measurements to be made with greater or less accuracy. They are both single-purpose and multi-purpose gauges made of various materials, such as wood, metals and their alloys or plastics, by means of which the user can determine the required dimension with greater or lesser comfort.

Among other solutions is known patent CZ 279 352, which solves the construction of a universal protractor, which consists of a semicircular protractor disc, whose diameter is flipped to a fixed protractor arm and to the center is connected to the second protractor arm with a reading index. It is a more complex measuring mechanism for measuring angles only and not for making them, and is equipped with two additional parallelograms to move the measuring arms away from the protractor. Its disadvantage is that it allows to measure only internal angles in the range of 0 ° to 180 °, while angles 0 ° and 180 ° and angles close to them from constructional

-2 • · · · · · · · · cannot be changed. A solution according to GB 2 352 039 for a two-dimensional measuring device at the same time is also known. It is a jig consisting of two rulers of rectangular cross section with a central longitudinal bore formed and connected to each other by a joint, which is equipped with a protractor disc. Both rulers can be adjusted to measure not only the angle between the two arms but also their length. The disadvantage of this solution is that the base surfaces of the rulers are not in one plane, the fixture is intended only for measurement and not also for creating angles and the tightening central joint is not equipped with any indexing device for jumping the rulers to selected angles.

The object of the published patent application US 2003/0074800 is the construction of a slide-out ruler with fixation of the position of the ejected part. It is based on a double-sided ruler, which is provided with a T-groove on the underside for guiding a narrower ruler of rectangular cross-section. This inner ruler can be pulled out of the basic ruler by a certain step, the size of which is determined by the distance of the holes created in the basic ruler. The pull-out ruler is then fixed in the selected position by a spring pin that fits into the holes of the basic ruler. The disadvantage of this solution is the fact that it serves only for simple extension of the measuring scale of the basic ruler and, moreover, the reading scale does not lie in line with the scale of the basic ruler, which affects the accuracy of the measurement. It is also known to provide a protractor in conjunction with a folding rule according to DE 195 34 059, which relates to a special purpose accessory which enables the measurement of angles by means of a folding rule with the possibility of arresting the desired angle. The disadvantage of this construction is that the angle joint swivel joint is not equipped with any indexing device for the angular adjustment step.

The common disadvantage of all known solutions is that they do not allow complex use, ie after a simple operative adjustment or replacement of components, measure the length, angles, perpendicularity of the surfaces or create angles or draw circles, while guaranteeing the accuracy of performed tasks.
