Invention herewith described refers to the three-dimensional numbers for marking used to mark all those objects which, for some reason, need to be sorted, classified and marked. The invention in its basic version consists of the base plate (1) and three-dimensional numbers (20-29) and there are a total of ten. The essence of the invention represent the holes in the base plate (1), whose arrangement is given in advance and this arrangement conforms to the arrangement of connecting elements on the back of the three-dimensional numbers (20-29), so that when assembling, the connecting elements are simply inserted into the holes and then form an assembly by means of bolts without any preliminary work. In the variant I of this invention as an assembly element also appears the support plate (7) that allows the entire system to be mounted on the object of marking in a simple and effective way, using only one bolt. |
