Definitions
- the invention relates to a compass with a first Leg that carries a centering needle and one on the shaft second leg is articulated, which is a drawing element wearing, the first or the second leg one Handle part for drawing.
- Known circles comprise two legs.
- One of these Leg has a centering tip at its lower end or the like, the other leg has on his lower end of a lead mine cradle or for a common writing instrument, such as a pencil, Pens etc. on.
- the two legs open up their upper ends in a compass head assembly, which as top part an at least almost cylindrical shape Grip part for the user includes.
- Such handle parts are usually provided with a border. Due to the Compass head assemblies have a pleasant handling enforced, in which the axis of the handle part in the Bisectors between the axes of the two Compass leg is guided with a straight guide.
- the object of the invention is the head assembly of a Compasses with a handle for drawing like this execute that good handling and Operational reliability achieved and a complicated and Straight guidance of the handle part, which is susceptible to repair, is unnecessary becomes.
- first leg with its joint for storage on the second leg in a longitudinal slot in the shaft of the second leg arranged, the longitudinal slot preferably with small spreads the first leg embraces and stabilizes the torsional stiffness acts between the legs.
- a tapered transition part between the handle part and the the leg supporting it advantageously has a surface on which by rotating a circular line or a a similar flat line segment is created around an axis, which is in the plane of the circular line at a distance of the convex side of which is a part of a near the axis Is torus.
- the essentially rotationally symmetrical surface of the The area of the handle part can be that of a part of a Rotational ellipsoids with slightly different ones Be semi-axles.
- the second leg advantageously has means for receiving and fixation of interchangeable writing utensils, such as Pencil, pen or the like as Drawing element.
- interchangeable writing utensils such as Pencil, pen or the like as Drawing element.
- the advantages achieved with the invention include Property of the sphere-like area of the handle part, especially in the case of a targeted to a leg inclined approach axis, even when pulling one Circular line between thumb and forefinger without any problems pass on if the figure axis of this area their situation changes.
- the tapered transition part between Handle part and compass leg serves as Orientation guide for the tip of the index finger.
- a compass shown schematically in FIGS. 1 and 3 comprises a first leg 1, which is known per se Kind of a centering needle 2 to put on and fix the Circle in the center of the circle to be drawn.
- the leg 1 is at its head end, i.e. with his the Centering needle 2 opposite end in one Longitudinal slot 3 of a second leg 4 by means of a Bearing screw 5 articulated, as the detail of FIG. 2 in more detail shows.
- the longitudinal slot 3 is in the leg 4 in the form of a central flat groove on the side facing the leg 1 formed and extends from the bearing screw 5 to to an angled point 6 of the leg 4.
- the Longitudinal slot 3 and the shaft 7 of the leg 1 are so dimensioned that the longitudinal slot 3 in particular small spreads of the compass at least with the shaft 7 part of the slot length and stabilizing the torsional stiffness between the legs works.
- the bearing screw 5 produces a U-shaped slotted profile of the leg 4 an axial pressure on the shaft 7, so a suitable one due to the resulting friction Friction torque between legs 1 and 4 adjustable given is.
- the second leg 4 carries one at its lower end Opening 8 and a clamping screw 9 for receiving and Fixation of interchangeable writing utensils 10, such as Pencil, pen or the like as Drawing element.
- the second Leg 4 rigidly connected to a handle part 11, which an area 12 with an axis 13 includes rotationally symmetrical surface.
- the diameter of the area 12 increases from a maximum value along the axis 13 up and down like a ball.
- the surface of the Area 12 essentially as part of a Rotational ellipsoids with slightly different ones Semi-axes executed, with deviations from this area through corrugations or similar designs Improvement of the grip are given.
- transition part 14 is provided between the handle part 11 and the second one carrying it Leg 4 .
- the surface of the transition part 14 is closer to the axis Part of a torus, so it is geometric generated by rotating a circular line or the like flat line segment around the axis 13, the axis 13 in the plane of the circular line at a distance from it convex side.
- the surface of the spherical area is advantageous 12 of the handle part 11 in a manner known per se Corrugations or depressions similar in effect or Provide increases to improve ease of use. For the same reason, this surface is one Made of material that is high Coefficient of friction to the skin on the fingers of one Has user person.
- the thickness of the handle part 11, i.e. is the maximum diameter of the area 12 expedient in the range of the thickness of the fingers of a user person chosen. If, as usual, when drawing this Handle part 11 rolls between your thumb and index finger the thickness of the handle part is smaller than that of the Index finger tip, preferably a thickness equal to 11 mm proven advantageous. With this roll it allows tapered transition part 14 an unimpeded operation.
- Fig. 1 and 3 show on the first leg 1 a widened handle 15.
- the lower part 16 corresponds to the handle part 15 of the second leg 4 adapted.
- the thigh 4, which carries the drawing element 10, and the Handle parts 11 and 15 are preferably made of plastic manufactured, e.g. B. from acetal resin with the trade name Delrin 100 from DUPONT, made of polyamide with the trade name Zytel from DUPONT, or made of polyester with the trade name Valox from General Electric.
