Definitions

  • This invention relates to multi-pencils and, in particular, to a one-hand operated multi-pencil for dispensing extrudable, cartridge contained drawing materials.
  • an "axial line” means a center line which extends from a center 38 of an exit aperture 24 of a barrel 16 to a center 40 of an upper end 34 of a main body 18.
  • An “axial direction” means a direction along the axial line in a forward or upward direction and in an aft or downward direction, where “downward” or “aft” corresponds to a direction from the center 40 of the upper end 34 of the main body 18 towards the center 38 of the exit aperture 24 of the barrel 16 and “upward” or “forward” corresponds to a direction from the center 38 of the exit aperture 24 towards the center 40 of the upper end 34 of the main body 18.
  • the barrel 16 and the main body 18 are interconnected by means of a generally cylindrical mid-body 20. Disposed within the mid-body 20 is a main body biasing spring 36, which biases the main body 18 away from the barrel 16 in an axial direction.
  • the engaging sleeve 212 is a hollow, cylindrical element having an aft end 300 and a forward end 302.
  • the aft end 300 features engagement features 282 that engage via a press fit with the engagement features 280 of the movable sleeve 220.
  • the forward end 302 includes a socket 216 with engagement features that engage with the flexible fingers 202 of the operating rod 48.
  • the pushing rod 228 is a cylindrical rod having a main body portion 310 having a forward end 307, an outside diameter 274 and an aft portion 306 having an outside diameter 312 and an end pad 308.
  • pushing rod 228 is made from a metallic material.
  • the pushing piston 230 is a cylindrical component having an aft cup portion 314 and a forward cup portion 316.
  • the aft cup portion 314 serves to engage an end of the drawing material 14.
  • the forward cup portion 416 engages the aft portion 306 of the pushing rod 228.
  • the operation of the cartridge assembly 210 to cause the drawing material 14 to be extruded from the cartridge assembly 210 is as follows. With reference to Fig. 1 , the cartridge assembly 210 is shown at rest within the barrel 16.
  • axial downward movement of the locked-in-place slide member 46 causes the engaging sleeve 212, via the operating rod 48, to move downwardly inside the spring retainer 224. Because the engaging sleeve 212 is fixed to the movable sleeve 220, the movable sleeve 220 also moves downwardly or aft, as well. The movable sleeve 220 holds the material pushing rod 228 in place by friction. Therefore, the material pushing rod 228 also moves downwardly and through the pushing rod support portion 272 of the material holder 222. The pushing piston 230 being connected to the material pushing rod 228 also moves downwardly through the material holder 222, thereby advancing the drawing material 14 within the material holder 222 and out the open aft end 252 of the material holder 222.
  • the tapered, hollow, cylindrical sleeve 232 moves aft or downwardly as well, as it is engaged with and rides along with the movable sleeve 220.
  • the tapered, hollow cylindrical sleeve 232 moves downwardly or aft until the lip 328 of the sleeve 232 abuts the cylindrical stop surface 328 of the material holder 222.
  • the main body biasing spring 36 drives the main body 18 upwardly or forward.
  • the biasing spring 226 of the cartridge assembly 210 drives the engaging sleeve 212 and the connected movable sleeve 220 upwardly or forward relative to the spring retainer 224 and connected material holder 222.
  • the movable sleeve 220 being disengaged from the material pushing rod 228 moves upwards or forward over the material pushing rod 228, while the material pushing rod 228 remains stationary.
  • the slide member 46 includes an upper (forward) portion 110 and the operating rod 48.
  • the upper (forward) portion 110 includes a finger tab 112, a striker 114, guides 116, catches 136, a spring abutment surface 124, and a disengagement member 118.
  • the disengagement member 118 features a rear angled surface 120 and two mutually opposed side, angled surfaces 122.
  • the main body includes the lower (aft) cylindrical portion 28 and the upper (forward) portion 30.
  • the upper (forward) portion 30 includes four slots 44 spaced equidistant about the perimeter of the main body 18.
  • Each slot 44 has a first end wall 130 and a second end wall 132.
  • Located within each slot 44 is an upper pair of angled upper surfaces 128 and a pair of lower ledges 126 (see Fig. 12 ).
  • the lower ledges 126 extend from side walls 134 of the slot 44 and which run in an axial direction partially along the length of the slot 44.
  • the lower ledges 126 terminate forward of the second end wall 132 of the slot 44 at ledge end point 152.
  • the upper angled surfaces 128 and lower ledges 126 form a guide channel 134.
