Definitions

  • the present invention relates to a rotary-cam ball-point pen in which a refill pen point can be pushed out of the head member of the ball-point pen against the elasticity of an elastic body by knocking the rear end of the ball-point pen.
  • the ball-point pen can be maintained with the pen point pushed out of the head member of the ball-point pen, by a rotary-cam engaging a cam body.
  • the pen point can be withdrawn into the head member of the ball-point pen by the elasticity of the elastic body by releasing the engagement of the rotary-cam with the cam body.
  • a conventional rotary-cam ball-point pen has an outer sleeve, a rotary-cam mechanism comprised of a cam body provided on the inside of the outer sleeve, a rotary-cam engaging the cam body, and a cam bar engaging the rotary-cam.
  • a refill being a rear portion is loaded backward by a spring provided between the head member screwed on the forward end of the outer sleeve and a spring bearing formed on the refill so that the rear portion of the refill is forced into the rotary-cam.
  • a rotary-cam ball-point pen having an outer sleeve, a rotary-cam mechanism comprised of a cam body provided on the inside of the outer sleeve, a rotary-cam engaging the cam body, and a cam bar engaging the rotary-cam.
  • a refill has a rear portion loaded backward by an elastic body being inserted into the rotary-cam, wherein the cam bar has a structure with flexibility in which the cam bar can be distorted inward by applying a radial force.
  • a rotary-cam ball-point pen has the above-mentioned structure, when the rotary-cam mechanism and refill are set in the outer sleeve, the rotary-cam mechanism and refill are inserted from the forward end of the outer sleeve in a state where the rear portion of the refill is inserted into the rotary-cam, an elastic body is put on the forward portion of the refill, and the head member is screwed on the forward end of the outer sleeve by which the rotary-cam, the refill, the elastic body and the head member are set up.
  • the cam bar is inserted into the outer sleeve from the rear end of the outer sleeve, while the cam bar is deformed inward by the elasticity of the cam bar, which elasticity enables the projections of the cam bar to get over the rear portion of the cam body into grooves of the cam body by which the attachment of the cam bar to the cam body is made.
  • the number of parts is decreased, and less time is required for assembly of parts.
  • the cam body may be provided with a guide, which guides the projections of the cam bar.
  • the guide guides the projections of the cam body.
  • the cam bar may be formed with slits or cuts.
  • the slits or cuts give flexibility to the cam body so that the cam bar can deform inward by applying a radial force to get over the rear portion of the cam body and go into the grooves of the cam body.
  • a rotary-cam ball-point pen according to the present invention comprises outer sleeve 1, and cam mechanism 5 comprised of cam body 2 provided on the inside of the rear part of outer sleeve 1, Rotary-cam 3 engages cam body 2 and cam bar 4 engages rotary cam 3, and refill 7.
  • Cam body 2 may be formed integrally with outer sleeve 1 or cam body 2 may be attached to the inside of outer sleeve 1 by a force fit, adhesion, or screwing.
  • Spring 6 is provided between spring bearing 14 on refill 7 with its rear end is inserted in to rotary cam 3 and head member 13 removably screwed on the forward end of outer sleeve 1. The attachment of head member 13 to outer sleeve 1 is made by insertion, engagement, or screwing.
  • Cam bar 4 has a structure with flexibility in which the cam bar can be distorted inward by applying a radial force.
  • the number of projections 84 of cam bar 4 equals the number of grooves 9 of cam body 2, for example 9, but usually less than 6, or for example 2(Figs 3(a) and (b) ). Pairs of projections are diametrically opposed.
  • the number of projections 163 of rotary cam 3 is 3 in this case(Figs. 3(a) and (b) ).
  • cam faces 174 of cam bar 4 engage cam face 183 of rotation cam 3, and projections 84 of cam bar 4 and projections 163 of rotary-cam 3 are inserted into grooves 9 of cam body 2. Further, the engagement of cam face 183 of rotary cam 3 with cam face 192 of cam body 2, and the insertion of projections 163 of rotary-cam 3 into grooves 9 of cam body 2 are alternatively made.
  • Reference number 21 designates a clip formed integrally with cam bar 4.
  • Fig. 2 illustrates in vertical section an important part of a second embodiment which has the same structure as the first embodiment, in which headed cam body 2 is attached to the inside of the rear end of outer sleeve 1 by screwing.
  • cam bar 4 When pen point 20 of refill 7 is drawn into head member 13 of outer sleeve 1, the rear end of cam bar 4 is knocked releasing cam faces 183 of rotary cam 3 from cam faces 192 of cam body 2. Thereafter projections 163 of rotary cam 3 and projections 84 of cam bar 4 are inserted into grooves 9 of cam body 2 while refill 7 is moved backward drawing pen point 20 of refill 7 into head member 13.
  • cam bar 4 is inserted into outer sleeve 1 from the rear side, it is possible to form a clip 21 from the integral part of cam bar 4 (Fig . 1), or a decoration having a size larger than the outside diameter, or a knocking cap.
  • cam body 2 may be provided with guide 10 as shown in Fig. 4, which guides projections 84 of cam bar 4 so that the projections are easily inserted into grooves 9 of cam body 2.
  • cam bar may be formed with slit 11(Fig. 3(a) ), or cut 12( Figs. 5 and 6), which facilitates cam bar 4 deforming inward to get over rear portion 15 of cam body 2 to enter into grooves 9 of cam body 2 .
  • Slits 11 may be slits having one side open.
