Definitions
- the invention relates to a pencil, in particular a soft lead pencil for cosmetic purposes
- Such pins have a sleeve-like shaft with a front and a rear end, a push rod arranged coaxially in the shaft and fixed at one end to the rear end of the shaft in the axial direction, and a lead connected to the free end of the push rod.
- the shaft and the front part are in accordance with Art of a screw mechanism rotatably connected to one another
- the front part can be telescopically inserted into the shaft.
- the front part releases the lead, which is fixed in the axial direction with respect to the shaft.
- Such soft lead pins are described, for example, in US Pat Known soft-lead pencils, the front part also performs a relative rotational movement with respect to the mine when retracting or extending. Because of its often sticky and soft consistency, the mine can stick to the inside of the front part, especially when not used for a long time n retracted the front part, the mine can shear off due to the relative rotation between the front part and the lead
- the object of the invention to improve a pin of the type mentioned in this regard.
- This object is achieved in that the lead is rotatably connected to the push rod. If the lead sticks completely or only in sections to the inner surface of the front part, this does not have a disadvantage, at least when the front part is moved in, since the lead can rotate with the front part due to its rotatable fixation on the push rod. Shearing of the lead is thus prevented.
- An embodiment according to the invention is also expedient in the case of pins in which the front part and shaft non-rotatable are connected to each other and the push rod designed as a screw spindle and interacting with the front part is rotatably mounted in the shaft
- the lead is from the one pointing to the tip of the pen. End of a lead holder held The other end of the lead holder is rotatably fixed to the push rod, the lead holder being connected to the front part in a torque-locking manner.
- the lead is prevented from shearing even with lead masses with a very soft consistency does not take place here via a friction or material connection between the lead and the front part, but preferably by means of a positive connection between the front part and lead holder effective in the direction of rotation.
- the inner surface of the shank-side portion of the lead holder, a circumferential fixing groove available -, ⁇ , is *, in which a arranged at the tip end of the push rod ring projection in the manner of a snap connection engages
- the screw-type connection between the shaft and the front part is designed in such a way that the push rod is rotationally fixed to the shaft
- FIG. 1 shows a longitudinal section of a pin according to the invention
- 2 shows the longitudinal section of a pin according to FIG. 1 with a lead shortened by use and with the front part inserted into the shaft
- FIG. 6 shows the end of the front part of a pin according to the invention which cooperates with the push rods
- the main components of a pin are a sleeve-shaped shaft 1, a sleeve-shaped front part 2, a push rod 3, a lead holder 4 and a lead 5.
- the push rod 3 is an essentially cylindrical part with a extending helically around its central longitudinal axis 6 and forming an external thread.
- the rear end of the shaft 1 is closed by a base 8, while the front end of which is open for receiving the front part 2.
- the end of the shaft 12 facing the shaft base 8 in the assembled state has the push rod 3 a section with a larger diameter, namely a head part 9
- a flange 13 is arranged at a distance from the rear end 12 of the push rod 3 and has two diametrically opposed locking projections 10 on its peripheral surface.
- the locking projections 10 engage in complementarily shaped locking recesses 11 (FIG. 5 ) in the inner surface 14 d
- the shaft 1 is rotatably fixed with respect to the shaft by this embodiment.
- a fixation in the axial direction is brought about by a ring projection 15 arranged at a distance from the flange-like widening and near the end 12, which is radial from an annular surface 14 of the shaft 1 inward projecting fixing projection 16 is engaged on the side facing the flange 13.
- the flange 13 bears against a stop shoulder 21 which faces the pin tip 17 and projects radially inward from the inner surface 14
- the end region of the push rod 3 facing the pin tip 17 has no external thread.
- This end region is in a first region 20 which adjoins the external thread or the screw groove 7 and a subdivided the and extending to the end 18 of the push rod second area.
- the first region 20 has a diameter which corresponds to that of the region of the push rod which is provided with an external thread.
- the second area has a smaller diameter and is used to fasten the lead holder 4.
- the lead holder 4 is essentially a sleeve which, in the assembled state, is pushed with one end onto the second area 23 of the push rod 3. The area 23 is thus encompassed by one end of the lead holder 4 in the assembled state.
- a radially inwardly projecting ring projection 24 is arranged on the inside of the lead holder, which engages in a constriction 19 of the second region 23 in the manner of a snap connection in the assembled state.
- the lead holder is fixed in the axial direction, but is rotatably connected to the push rod 3.
- the lead 5 lies axially and rotationally fixed at one end.
- the lead holder has essentially the same diameter as the region 20.
- Push rod 3 and lead holder 4 are arranged centrally in the shaft, the lead holder 4 partially protruding from the shaft or from the shaft opening 25 arranged at its front end facing away from the shaft bottom 8.
- a hollow cylindrical receiving space 22 for receiving the front part 2 is arranged between the inner surface 14 of the shaft 1 and the outer peripheral surface of the push rod 3 and the lead holder 4.
- the front part lies at least partially in the receiving space 22 and includes the push rod 3, the lead holder 4 and the lead 5, so it is arranged coaxially with these parts.
- the lead holder 4 seen in cross section, has an octagonal outline shape.
- the inner surface 31 of the front part is designed to be complementary, that is to say the lead holder 4 lies in the front part 2 with a positive engagement which is effective in the direction of rotation.
- the end of the front part 2 lying in the shaft 1 or facing the shaft bottom 8 has two diametrically opposed windows 26. These windows are approximately U-shaped and each delimit an axially extending clamping jaw 27, the free end of which points towards the shaft bottom 8 on its inside facing the push rod 3 each have a locking cam 28 which engages in the screw groove 7.
- the front part 2 is in this way motion-coupled to the push rod 3 in the manner of a spindle nut.
- the clamping jaws 27 have a first section 29 and a second section 30 on the the second section 30 then extends on the first section 29 to the free end of the clamping jaws 27.
- the upper side 32 of the sections 30 is chamfered towards the free end of the clamping jaws 27.
- Inner surface 14 of the shaft 1 on The first section 29 has e a smaller wall thickness than the second section 30.
- the end region of the front part 2, which has the clamping jaws 27, merges with an oblique shoulder 34 into a region of larger diameter, the outer circumferential surface of which cooperates with the inner surface 14 of the shaft in the sense of a sliding guide
- a protective cap 35 which may be attached to the shaft 1, is first removed.
- the front part is in a maximally extended position.
- the locking cams 28 are arranged on the tip-side end of the screw groove 7
- the lead 5, which has not yet been used, is so long that it protrudes with a protrusion from the front part 2 , 4) is rotated because the lead holder 4 is rotatably connected on the one hand to the push rod 3 and on the other hand is encased in the direction of rotation 31 with positive engagement on the front part, the lead 5 is also rotated in the direction of rotation 39 is thus prevented
- the locking cams 28 move along the locking groove 7, so that the front part 2 is moved in the retraction direction 40, the shaft 1 and the front part 2 are so long against each other rotates until there is sufficient mine protrusion again.
- the front part 2 can be moved in the direction of insertion 40 until its shaft-side end abuts the head part 9 of the push
- the procedure for assembling a soft lead pin according to the invention is approximately as follows. First the lead holder 4, which is equipped with a lead 5, is pushed onto the push rod. The insertion movement runs in the direction of the central longitudinal axis of the pushing part or lead holder and the lead 4 into the constriction 19 of the push rod 3. Next, the front part 2 is pushed from the pin tip 17 over the lead 5 and finally over the lead holder 4 until the clamping jaws 27 engage with the locking cams 28 in the screw groove 7. i, the part 2 on the lead holder 4, the clamping jaws 27 are deflected radially outward in the direction of the arrows 38. The sections 29 of the clamping jaws with reduced wall thickness act as quasi film hinges This insertion movement ends the flange 13 on the stop surface 21 on the inner
