Definitions

  • This invention relates to a tape or ribbon cartridge and, more particularly, to a preassembled brake but­ton/spring assembly for such a cartridge which facili­tates overall assembly of the cartridge and promotes proper alignment of the spring therein.
  • Ribbon cartridges known in the art as "Segoma” cartrid­ges, include a single, circular ribbon spool biasly oriented within a square catridge.
  • the cartridge has an opening in the periphery to allow the ribbon on the spool to be withdrawn from the cartridge.
  • the spool includes a hub which, in the assembled car­tridge, surrounds a circular brake button biasly mount­ ed in the cartridge by a coil spring.
  • the brake button is intended to "brake” or prevent rotation of the spool, except when desired. That is, the coil spring normally biases the brake button against the hub to interlock corresponding, respective teeth and “brake” the spool. Only when the brake button is pushed back into the car­tridge against the force of the spring via, e.g., the external drive means, can the hub be rotated and the ribbon dispensed.
  • the spring is loosely mounted on a projection formed on the second half of the cartridge. Then, the brake button is loosely mounted on the coil spring, the hub is loosely mounted on the brake button and the first half of the cartridge is mated to the second half.
  • a cartridge having a preas­sembled brake button/spring assembly including a brake button with a set of tabs formed radially on the under­side thereof. These tabs direct, center and contain one end of the spring relative to the brake button during assembly, thus preventing the spring from falling off or becoming misaligned in the cartridge during assembly and use, and ensuring proper operation of the brake button by the external drive means.
  • the brake button includes a cross-shaped recess for receiving a corres­pondingly shaped projection formed on the second half of the cartridge. This configuration facilitates automated mounting of the brake button and prevents binding of the brake button during mounting or use.
  • FIG . 1 illustrates a conventional "Segoma" type cartridge indicated generally by reference numeral 10. Such a car­tridge is also shown and described in U.S. Patent No. 4,383,660, issued to RICHARD et al.
  • the cartridge 10 includes a first half 11 and a second half 13. Each half 11, 13 has an opening 12 in the peri­phery thereof to allow the ribbon or tape 14 wound on a spool 16 to be withdrawn from the cartridge 10 via a leader 18, as known in the art.
  • the spool 16 includes both a hub 17 and a planar flange 19 formed integrally thereof. There is also an opening 20 in the first car­tridge half 11 which allows an external drive means (not shown) access to the hub 17 to rotate the hub 17 during operation and supply the tape 14.
  • the brake button 24 includes a circular disk 27, a first upper projection 29 and a second, substantially rectan­ gular lower projection 31.
  • the second, lower projection 31 includes a corresponding rectangular recess 33 which, during assembly of the cartridge 10, is mounted on a si­milarly sized rectangular projection 26 formed on the second half 13 of the cartridge 10.
  • the brake button 24 is biasly mounted within the car­tridge 10 via a coil spring 28.
  • a first end 30 of the spring 28 abuts the underside 25 of the brake button 24 and the second end of the spring 32 abuts the second half 13 of the cartridge 10 to normally bias both the brake button 24 and the spool 16 resting thereon in the direct­ion of the first half 11 of the cartridge 10.
  • the conventional brake button/spring assembly does not prevent the spring from falling out of the cartridge during assembly. It is also very possible for the spring 28 to become oriented off-center of the brake button 24 during assembly or use. Further, due to the misalignment of the spring, the brake button 24 might be improperly installed and effectively disengaged, which disadvantageously allows dispensing of the ribbon when the cartridge 10 is not coupled to the external drive means. In addition, the misaligned spring 28 may inter­fere with proper coupling of the external drive means with the brake button 24.
  • the present invention overcomes these drawbacks, as will now be described in relation to the preferred embodiments of the present invention shown in FIGS 2-4, by providing means for ensuring positive, concentric mounting of the spring relative to the brake button.
  • the cartridge 55 of the present in­vention generally includes a spool 56 and a brake but­ton/spring assembly 57 located between first and second halves 58 and 59, respectively, of the cartridge 55.
  • the brake button 60 is substantially circular and gene­rally includes a substantially flat disk 61, an upper projection 63 and a lower projection 65.
  • the brake button 60 also includes a means 70 for fixedly retaining a spring 62 thereon during assembly of the cartridge 55.
  • a means 70 for fixedly retaining a spring 62 thereon during assembly of the cartridge 55 By fixedly it is meant that the spring 62 is attached to the brake button 60 and will not fall off thereof, even though the spring 62 may be able to par­tially rotate about its axis while mounted in the retain­ing means 70.
  • Retaining means 70 is formed to extend from the underside 71 of the brake button 60.
  • the retaining means 70 preferably includes an abutting surface 67 which is angled relative to the disk 61 and a retaining surface 68 thereunder parallel to the disc 61.
  • the retaining means 70 is two opposing bosses or tabs 70 ⁇ integrally molded to be equally, radially, spaced about the under­side 71 of the brake button 60.
  • the brake button/spring assembly 57 also includes a coil spring 62 having a first end 64 and a second end 66.
  • the first end 64 can be fixed to the underside 71 of the brake button 60 by screwing or snapping, whereas the se­cond end 66 of the spring 62 is a free end.
  • the retaining means 70 receives the first end 64 of the spring 62 to maintain the spring 62 in the desired position, i.e., on center with the brake button 60, as illustrated by the coincident axes "X" of the brake button 60 and the spring 62, shown in FIG. 3.
  • the lower projection 65 of the brake button 60 is preferively a cross-shape and includes a corresponding cross-­shaped recess 73 formed therein, which receives in slid­ing relation a cross-shaped projection 75 formed on the second half 59 of the cartridge 55.
  • a cross-­shape is the equivalent of four, substantially columnar projections extending from the second half 59 of the cartridge 55.
  • the combination of the cross-shaped recess 73 and projection 75 leads to less binding therebetween during assembly and operation of the brake button 60.
  • this configuration facilitates assembly by mak­ing the machine's task of mounting the brake button 60 on the second half 59 of the cartridge 55 easier.
  • FIGS. 3 and 4 The methods for assembling the brake button/spring assembly 57 and overall cartridge 55 according to the present invention are also illustrated by FIGS. 3 and 4.
  • the first end 64 of the spring 62 can be pushed down against the abutting surface 67 of the retaining means 70 as indicated by arrows "A" in FIG. 4.
  • the first end 64 necessarily expands an extent great enough to pass over the edge 69 of the retaining means 70 and returns to its original shape under the retaining means 70, i.e., within an annular channel 72, and against the retaining surface 68.
  • the spring 62 can be placed against the underside 71 of the brake button 60 and screwed on, i.e., turned until the first end 64 is caught under the retaining means 70.
  • the retaining means 70 requires only minimal modifications to the structure of the cartridge. 55.
  • the retaining means 70 does not otherwise interfere with assembly or operation of the cartridge 55.
  • the retaining means 70 al­lows positive seating of the spring 62 relative to brake button 60 once assembled.
  • the easy snapping or screwing assembly of the spring and brake button can be easily reversed, if desired. In this manner, if either the spring or injection molded brake button is defective, the parts can be separated, the defective part scrapped and the non-defective part reused.
  • the means for mounting the brake button 60 relative to the second half 59 of the cartridge 55 further facilitates assembly and prevents binding and wobbling of the centered brake but­ton 60.
