Definitions

  • the invention relates to a wooden pencil for painting, writing, drawing or for cosmetic with the features of the preamble of claim 1.
  • a wooden pencil for painting, writing, drawing or for cosmetic with the features of the preamble of claim 1.
  • Such a pin is formed of two half-legs, in each of which a groove extending in the longitudinal direction of the groove is present.
  • the grooves together form a central, a mine receiving cavity.
  • the groove of a shaft half is flanked by two connecting surfaces, which are glued to the connecting surfaces of the other shaft half.
  • the connecting surfaces of each shell half extend in a common plane plane which, at least approximately, intersects the central longitudinal axis of the pencil.
  • the shaft halves have a cross-sectional shape corresponding to a semicircle.
  • the object of the invention is to propose a pen that can be produced with less waste than conventional wooden pencils.
  • each shaft half do not extend completely in a common plane plane. It has surprisingly been found that a pin with such a configuration has a reduced tendency to bend, in particular due to different moisture content of the sheep halves.
  • the sheep halves or the connecting surfaces located there there is a large variety of possible variations. If, as is provided in a preferred embodiment, the sheep halves are colored differently, there are many optical design options for the pointed cone of the pen.
  • leg halves are formed as equal parts, which simplifies the production of pins, since for a given type of pin only uniformly shaped leg halves have to be produced.
  • Fig. 1 is a wooden pin, in the following is spoken simplistic of a pin 1, shown, the shaft 2 is formed in a conventional manner from two separate in the longitudinal direction of the pin or in the direction of the central longitudinal axis 3 of the pin 1 sheep halves 4a, b.
  • the sheep halves consist for example of jelutong, gmelina or cedar wood.
  • the pin 1 has a pointed cone 5 at the latest after the first tip with the aid of a pen tip.
  • each leg half 4a, b is a in the pin longitudinal direction 3 extending groove 6 is introduced.
  • the grooves 6 form in the finished pin 1 a central, a mine 7 receiving cavity 8.
  • the groove 6 is in each case of two extending in the pin longitudinal direction, in plan view Fig. 2 formed substantially rectangular connecting surfaces 9, 10, which are connected to each other in the finished pin 1 by gluing.
  • the sheep halves such as Fig. 3 can be seen, designed so that their connecting surfaces 9, 10 extend in a common plane plane 12, wherein the plane plane 12, the central longitudinal axis 3 of the pin 1 intersects.
  • the shaft halves 4a, b are thus configured here in such a way that they are subdivided into two partial halves 14, 15, which have an identical shape, by means of a plane plane 13 which runs at right angles to the plane plane 12 and intersects the central longitudinal axis 3.
  • the plane 13 thus forms the mirror plane for the part-shank halves 14, 15.
  • Fig. 4 to Fig. 6 are as Fig. 4 to Fig. 6 it can be seen, the sheep halves 4a, b designed differently and in such a way that the connecting surfaces 9, 10 of each of the two leg halves 4a, b do not extend completely in a common plane Plane.
  • the sheep halves are interlinked in a certain way. Due to this configuration of the interconnected leg halves, the stiffness of the pin is increased, so that a bending transversely to the leg halves, ie approximately in the direction of the arrow 16 in Fig. 1 , is difficult.
  • the shape of the connecting surfaces 9, 10 can be designed very differently.
  • the connecting surfaces 9, 10 a first to the mine 7 receiving cavity 8 subsequent surface area 9 ', 10', said surface areas on a common, the central longitudinal axis 3 of the pin 1 intersecting plane plane 12 extend, which brings a manufacturing advantage with it.
  • a surface portion 9 ", 10" which is arranged outside the plane Plane and extends approximately on a circular edge.
  • the partial surfaces 9 ', 9 "and 10', 10" extend over the entire length of the shaft halves 4a, b and point in the plan view according to Fig. 2 a rectangular outline shape.
  • the two partial surfaces 10, 10 ' extend at a distance 18 and parallel to one another.
  • pin run the connecting surfaces 9, 10 of a shaft half 4a, b completely in Plankenen 19. It is here a similar configuration as in the pin of Fig. 4 , It only lacks the surface adjacent to the cavity 8 surface areas, which are arranged in a common plane plane.
  • the Plinkenen 19 also run parallel to each other and have a distance 18.
  • the in Fig. 5 shown pen has no round, but a rather triangular outline shape. Conceivable, of course, are other, for example, hexagonal or oval outline shapes.
  • pin which also has a triangular outline, has a connecting surface 9 of a shaft half 4a, b extending in the direction of the central longitudinal axis 3 of the pin rib 20 and the cooperating with their connecting surface 10 of the other shaft half 4a, b a complementary to the rib 20th gutted gutter 22 on.
  • a particularly noticeable interlocking of the sheep halves here.
  • At the surface of the rib 20 and the bottom of the groove 22 forming surface areas is followed on both sides by a surface area 9 ', 10' and 9 ", 10" with the first-mentioned surface areas extending away from the mine-receiving cavity 8 and extending the latter surface areas to the surface 23 of the sheep halves 4a, b.
  • FIG Fig. 4 For the production of a pin according to the invention, the example of FIG Fig. 4 As shown in the case of the production of conventional wooden pencils, it is assumed that two boards or boards 24a, b are used. In flat sides of the boards to be joined together, grooves 6 are milled in, which extend parallel to one another and are at a distance from each other. The grooves are each made the same and each form a 180 ° segment of the mine 7 receiving cavity 8. In the present between the grooves 6 surface regions 25, the connecting surfaces 9, 10 are formed, for example, milled. In the grooves 6 of the lower panel 24b mines 7 are inserted and then the two panels 24a, b connected by bonding to surface areas 25 and the connecting surfaces 9, 10 with each other.
