Definitions

the present invention relates to fastening and adjusting device, particularly for draughtsman compasses.
the draughtsman compasses of the known art are generally constituted by two hinged rods each having a point at its lower end; usually one of the two points can be substituted by a lead holder or a drawing pen, according to the case.
one of the two rods is shorter and a fastening member is hinged at its lower end for the lead holder or drawing pen element.
the fastening member is substantially constituted by a pair of jaws that can be tightened by a screw and by a knurled ring; furthermore, the fastening member is hinged with some friction in order to keep the selected angle during its use.
the fastening member has to be pivoted to the rod in order to vary its angle with respect to the rod because otherwise, when the compass aperture increases, the lead holder or the drawing pen would work at an excessive angle to operate correctly.
the locking of the lead holder or of the drawing pen can be improved, mainly regarding the speed of execution.
Main aim of the present invention is that of providing a fastening device for the lead holder or the drawing pen in a compass, having a rapid and easy operation and furthermore with an improved aperture with respect to the known ones.
an object of the invention is that of providing a device easily manufactured from a productive point of view and hence economically competitive.
a fastening and adjusting device particularly for draughtsman compasses comprising a pair of upwardly hinged rods, characterized in that it comprises a U-shaped element hinged at the lower end of at least one of said rods, said lower end having a substantially curved surface, said U-shaped element defining a cavity between its legs and said surface, a support member being inserted in said cavity and locked against said surface by means of an adjustable abutment member, said support member being adapted to support a lead holder,a drawing pen, a point or similar.
a compass 1 comprises two rods 2 and 3, upwardly hinged to a block 4 having a hand grip 5, in a per se known manner.
a U-shaped element 6 has two legs 7 hinged to the lower end of each of the rods 2, 3 in order to define a cavity 15 between its legs 7 and the surface 10 of the rod end.
a threading 8 is provided on the element 6, partially covering also the legs 7, for a locking ring 9.
a support element can be inserted in the cavity 15 for such elements as a lead holder, a drawing pen a point or similar.
a support element 14 for a point, applied to the lower end of rod 3, is schematically illustrated by dashed lines.
a support element 11 advantageously constituted by a single body comprising a drawing pen 12 juxtaposed to a lead holder 13.
the operation of the device is the following: as the desired aperture of the compass is set, the rings 9 are loosened to allow the U-shaped elements to rotate and to set them at the most suitable angle with respect to the working surface.
the abutment surface 10 of the lower ends of the rods 2 and 3 is a curved surface for easing the continuous locking of the support elements.
An advantage of the invention is that of allowing to incline and lock the end organs by the one easy operation of tightening a ring.
a further advantage of the device according to the invention is that of always ensuring a safe locking that depends on the tightening strength of the ring, which is adjustable at will and therefore does not suffer after some time from the wearing out of hinges or similar, as in the known compasses.
the device according to the invention may have numerous modifications and variations, all within the inventive concept; furthermore, all the details may be substituted with technically equivalent elements.
the materials employed, as well as the dimensions, may be any according to the specific needs and the state of the art.
