DETAILED DESCRIPTION OF THE 1PREFERRED EMBODIME1~TT
Referring to FIG. l, a storage rack is shown comprising a
pivot shaft 40, a plurality of trays 10;20;30., and ~ plurality of flat
accessories boxes 12;22;32 mounted in the trays 10;20;30. The
trays 10;20;30 each have a plurality of knuckles 11;21;31
respectively pivotally coupled to the pivot shaft 40 such that the
trays 10;20;30 are arranged in a stack and can be turned about the
pivot shaft 40 together or respectively relative to one another.
Positioning structure (not shown is provided between the pivot

shaft 40 and the knuckles 11;21;31 such that the trays 10;20;30 can
be respectively positioned in the desired angular position after
having been turned about the pivot shaft 40. The flat accessories
boxes 12;22;32 have different sizes, i.e., a tray 10;20;30 can carry
one big-size flat accessories box 12 (see FIG. 2), two medium-size
flat accessories boxes 22 (see FIG. 7), or four small-size flat
accessories boxes 32 6;see FIG. 8).
Referring to FGS. 2~6, each tray 10:;20;30 has at least two
locating blocks 50 upwardly disposed at the top and arranged at
right angles; each flat accessories box 12;22;32 has a plurality of
recessed bottom locating holes 51 corresponding to the locating
blocks 50 at the tray 10;20;30. Because the trays 10;20;30 and the
flat accessories boxes 12;22;32 are molded from plastics, the
locating blocks 50 are springy, and the recessed bottom locating
holes 51 are slightly expansible. When put the flat accessories
boxes 12;22;32 in the trays 10;20;30, the respective locating
blocks 50 are respectively press-fitted into the respective recessed
bottom locating holes 51, thereby causing the flat accessories
boxes 12;22;32 to be respectively firmly secured to the trays
10;20;30. The friction force between the respective flat accessories
boxes 12;22;32 and ~~he respective trays 10i;20;30 is sufficient to
firmly secure the into the respective recessed bottom locating holes
51, thereby causing the flat accessories boxes 12;22;32 to the trays

CA 02451537 2003-12-24
10;20;30, and the flat accessories boxes 12;22;32 do not fall from
the trays 10;20;30 when turning the trays 10;20;30 about the pivot
shaft 40.
Referring to FIGS. 2, 7, and 8, each tray 10;20;30 has two
oval through holes 13;23;33 symmetrically disposed near two
opposite lateral sides. The user can insert a finger through the oval
through holes 13;23933 to push the flat accessories boxes 12;22;32
upwardly away from the trays 10;20;30 in direction reversed to the
bonding direction between the locating blocks 50 and the recessed
bottom locating holes S1. Therefore, the recessed bottom locating
holes 51 can be smoothly disengaged from the locating blocks 50
without damaging the locating blocks 50.
Referring to FIG. 7, the tray 20 carrying two medium-size
flat accessories boxes 22 is seen after opening of the tray 10
carrying one big-size flat accessories box 12 from the other trays.
The medium-size flat accessories boxes 22 are about one half of the
size of one big-size flat accessor ies box 12. :Every medium-size flat
accessories box 22 lsas a plurality of bottom locating holes 51
disposed adjacent to three of the four sides thereof and connected
to corresponding locating blocks SO at the tray 20.
Referring to FIG. 8, the tray 30 carrying four small-size flat
accessories boxes 32 is seen after opening of the tray 10 carrying
one big-size flat accessories box 12 with th.c tray 20 carrying two

CA 02451537 2003-12-24
medium-size flat accessories boxes 22. The small-size flat
accessories boxes 32 are about one half of the size of one
medium-size flat accessories box 22. Every small-size flat
accessories box 32 has a plurality of recessed bottom locating holes
51 disposed adjacent to two of the four sides thereof and connected
to corresponding locating blocks 50 at the tray 30.
Referring to FIG. 9, one medium-size flat accessories box
22 and two small-size flat accessories boxes 32 can be carried in
one tray 20. By means of the recessed bottom locating holes 51 at
the flat accessories boxes 12;22;32 and the iocating blocks 50 at
the trays 10;20;30, the flat accessories boxes i<2;22;32 can
detachably and selectively set in the trays 10;20;30.
A prototype of storage rack has been constructed with the
features of the annexed drawings of FIGS. 1~9. 'The storage rack
functions smoothly to provide all of the features discussed earlier.
Although particular embodiments of the invention have
been described in detail for purposes of illustration, various
modifications and enhancements xnay be made without departing
from the spirit and scope of the invention. Accordingly, the
invention is not to be limited except as by the appended claims.
