Definitions

  • Writing apparatus has a great concern with the revolution of human civilization. It helps to let human history be transmitted from generation to generation. In the modern time, writing apparatus has become a requisite in our daily life. We may frequently need to use a writing apparatus to write or to draw.
  • a writing apparatus (1) is comprised of a pen-holder, a pen socket (12), a pusher means (13) and a lead (14).
  • the pen-holder (11) is a hollow cylinder having a vertical groove (111) set at one side to pierce through the side wall.
  • the pen socket (12) is a circular cone connected with the pen-holder (11) at one end, having a guide hole (121) set at the middle to pierce therethrough so as to provide a passage for passing therethrough of the lead (14).
  • the pusher means (13) is a short column comprising a curved wing portion (131) and having an outer diameter slightly bigger than the inner diameter of the pen-holder (11) such that when it is set in the pen-holder (11) it will be tightly retained inside the pen-holder (11) with the wing portion (131) stopped against the inner side wall of the pen-holder (11).
  • the pusher means (13) also comprises a push end (132) arranged in a thickness equal to the width of the vertical groove (111) of the pen-holder (11), which push end (132) is to be set to slide along the vertical groove (111).
  • the lead (14) is an elongated material set in the reducing hole (133) of the pusher means (13).
  • the lead (14) may be a pencil lead or a refill or a crayon.
  • the pusher means (13) When is use, the pusher means (13) is inserted into the pen-­holder (11), after the lead (14) is set in the reducing hole (133) of the pusher means (13), to let the outer surface be firmly retained by the inner wall surface of the pen-holder (11) and to let the push end (132) be retained in the vertical groove (111).
  • the pusher means (13) When the pusher means (13) is pushed toward the pen socket (12), the lead (14) will protrude beyond the pen socket (12) for writing.
  • the writing apparatus is comprised of a pen-holder (21), a pen socket (22), a pusher means (23), and a lead (24).
  • the pusher means (23) has an I-shaped cross section, and is comprised of a seat (231) and a push end (232), wherein the seat (231) which is comprising a pierced hole (233) is set side the pen-holder (21), and the push end (232) is set outside the pen-holder (21), so as to let the seat (231) and the push end (232) firmly retain the side wall of the pen-holder (21) and to let the vertical groove (211) of the pen-holder (21) firmly retain the neck portion of the pusher means (23) between the seat (231) and the push end (232), that is, the pusher means (23) is set to slide along the vertical groove (211) to push the lead (24) to protrude beyond the pen socket (22) for writing or to pull up the lead (24) to receive inside the pen-holder (21).
  • Figure 5 illustrates the third embodiment of the present invention which is comprised of a pen-holder (31), a pen socket (32), a plurality of pusher means (33) and a plurality of leads (34).
  • the pen-holder (31) is an elongated rod comprised of a solid central rod (311) having a plurality of radial wing bars (312) to define a plurality of vertical grooves (313) disposed thereamong and arranged in number equal to the number of the wing bars (312).
  • the pen-holder (31) is also having a reduced bottom end for easy connection with the pen socket (32).
  • the pen socket (32) is a cone body having a guide hole piercing through axial center for passing therethrough of the lead (34).
  • the bigger end of the pen socket (32) is properly arranged to match with the reduced bottom end of the pen-holder (31), such that the pen-holder (31) may be set in the pen socket (32) or screwed up with the pen socket (32) by means of screw joint.
  • the pusher means (33) includes a seat (331) having a push end (332) vertically extending upward and a tapered hole (333) made at the center for setting therein of the lead (34), wherein the tapered hole (333) may be completely piercing through the pusher means (33) or it may be blocked up at the middle part.
  • the tapered hole (333) is properly arranged to incline inward to facilitate setting therein of the lead (34).
  • the lead (34) is a writing element, which may be a pencil lead or ball pen refill or crayon or any other elongated writing element, of which the outer diameter is properly arranged to match with the hole (333) of the pusher means (33).
  • Figures 8 and 9 illustrate the fourth embodiment of the present invention, which is most suitable for use to match with fragile leads, such as pencil lead or crayon.
  • the pen socket (42), as shown in Figure 8 is having several holes (421) made thereon to aim at the vertical grooves for passing therethrough of the respective leads (44), that is, the number of holes (421) is equal to the number of vertical grooves,
  • the writing apparatus includes a single lead pen socket and a multi-lead pen socket respectively set at both ends of the pen-holder.
  • the writing apparatus may have a single lead pen socket respectively set at both ends or the writing apparatus may be equipped with multi-lead pen sockets at both ends.
  • the pen-holder (51) is respectively connected with a pen socket (52) at both ends.
  • the pusher means (53) has a hole (533) respectively made at both ends for setting therein of a lead (54) respectively, so as to allow one pusher means (53) control two leads (54) to slide along a vertical groove (513). Further, one vertical groove (513) may be matched with two pusher means (53) letting the pusher means (53) separately control a respective lead (54).
  • the pusher means (53) is firmly positioned by means of the friction force between the pusher means (53) with the two lateral walls of the associated vertical groove (513).
  • the pusher means (53) may be arranged to clamp down on the inner and outer walls of the associated wing bar (512) to become firmly positioned by means of the friction force between the pusher means (53) and the wing bar (512).
  • eraser or some other related accessories may be attached to the pusher means for specific application.
  • a clip or pen cap may be attached to the pen-­holder to make the structure become convenient to carry with oneself.
  • the pen-holder may be made of transparent material for easy identification of the writing elements contained therein.
