Claims
I claim:
1. A collapsible bookcase comprising a member of cardboard-like
foldable material having a one piece back wall, side walls folded
from the back wall to extend forwardly therefrom, flaps on the
upper and lower edges of the side walls folded therefrom and
extending toward each other, top and bottom walls folded from the
top and bottom edges of the back wall and each in two sections
folded with relation to each other through substantially
180.degree. and extending about and over the outer and inner
surfaces of the said side wall flaps and shelves of a length
substantially the distance between the side walls for resting on
the books contained on the bottom wall and on each shelf above it,
a front wall of substantially the size of the back wall with a flap
of two sections folded upon itself and interleaved with the
sections of the bottom wall.
2. A bookcase as in claim 1 wherein the front wall has a flap at
its upper edge to tuck in below the top wall.
3. A bookcase as in claim 1 wherein a tube of substantially the
entire length of the structure telescopes the structure.
4. A bookcase as in claim 1 wherein a front wall of substantially
the size of the back wall has a flap of two sections folded upon
itself and interleaved between a section of the bottom wall and a
flap of a side wall.
5. A bookcase as in claim 1 wherein a front wall of substantially
the size of the back wall has a flap of two sections folded upon
itself and interleaved between a section of the bottom wall and the
flaps of the side walls.
Description
BACKGROUND OF THE INVENTION
Various knockdown forms of containers such for instance as drawers,
cabinets or the like, have been formed but seldom are these in a
form for containing books either for storage or shipment. To ship
books or transport them from place to place has heretofore been
accomplished by utilizing conventional boxes which would only
accommodate one row of library books at a time. This manner of
shipping is time consuming and does not provide a temporary
bookcase as might be desired.
SUMMARY OF THE INVENTION
A bookcase in the form of a cardboard container having a back wall
with top and bottom walls reinforced by doubling the material on
itself and locking the side walls in place by means of flaps
extending therefrom is provided with shelving resting on the
contained books while a front wall when shipping is desired may
have a two-sectioned bottom to additionally reinforce the bottom
wall and tie the front wall thereto so as to cover the entire open
front of the case. Additionally a tube may be telescoped over the
top of the case for locking all of the parts together and also
reinforcing the package when shipping is desired. Shelves are
provided by resting the shelf upon the books as they are stacked
into the bookcase, the first shelf being positioned after the first
lower row of books is inserted onto the bottom wall by placing a
shelf on this row of books and then continuing to load a row of
books upon this shelf and then position another shelf thereon and
so on until the bookcase is filled.
DESCRIPTION OF THE DRAWINGS
FIG. 1 is a plan view of a blank from which the body part of the
bookcase is folded;
FIG. 2 is a plan view of the front wall;
FIG. 3 is a plan view of one of the shelves;
FIG. 4 is a central sectional view of the bookcase in assembled
position illustrating in dotted lines books which may be located on
the shelves of the bookcase; and
FIG. 5 is a perspective view of the tube which telescopes the
bookcase shelf shown in FIG. 4 when the front wall is swung up into
closed position .
DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to the drawings 10 designates generally a blank from
which the body part of the bookcase is formed. The blank is formed
of cardboard-like material scored along the dotted lines shown to
indicate where the folds occur at various parts of the body. The
vertical back wall is designated generally 11 with score lines at
12 for the folding of the vertical side walls 13 to extend
forwardly from the back wall 11. The side walls 13 are provided at
their ends with flaps 14 at the top of the side walls and 15 at the
bottom of the side walls. These flaps are folded along score line
16, 17 toward each other and overlap at their center portion where
the section of FIG. 4 is taken.
A bottom wall is folded along the score line 20 and is provided in
two sections 21 and 22 with a score 23 between them, and this is
folded to extend along the lower surface of the two folded-in flaps
15 (FIG. 4) and then over the outer edges of these flaps as at 24
and then inwardly as shown in FIG. 4 at 22. A top wall is folded
along the score line 24 and provided with two sections 25 and 26
folded along the score line 27. This top wall embraces the flaps
14, as shown in section in FIG. 4, by first extending over the
upper surface of these flaps 14 and then being folded about the
edge as at 28 with the section 26 extending inwardly to envelop the
two portions or flaps 14. Tabs 29 on the edge of the section 26 may
extend through the slots 29' in the back wall 11 so as to lock this
portion of the top wall in place.
A front wall shown in FIG. 2 is designated generally 30 and
comprises a portion 31 scored as at 32 at its lower edge to provide
a bottom flange having sections 33 and 34 on either side of score
line 35. These lower two sections are interleaved with the sections
22 and 15 of the bottom wall shown in FIG. 4 so as to hold this
front wall in position at its lower edge. Another score line 36
provides a flap 37 which may be tucked in below the section 26 of
the top wall to also hold the upper edge in place.
Books such as shown in dotted lines at 40 may be loaded into the
bookcase on the assembled bottom wall as shown in FIG. 4 and then a
shelf 41 laid on these books and additional books 42 placed in
position when a further shelf 41 may be positioned on these books
42 and additional books 43 positioned and a shelf 41 positioned on
these books and so on until the case is filled.
It will of course be understood that if the bookcase is to be used
in the form shown in FIG. 4 and just described the front wall will
be unnecessary. However, in assembling the books in place it may be
desirable to have some sort of a support as at 45 positioned along
the back wall and in engagement with the bottom wall and the
section 26 of the top wall so as to prevent the top wall section 26
from dropping down in position to interfere with the placing of the
books in the bookcase.
If it is desired to ship the bookcase with the books therein, a
telescoping sheath designated generally 47 of a size to envelop the
bookcase and its front wall as a whole may be provided. Thus there
will be formed a back wall 48 of the sheath, front wall 49 and side
walls 50 which may be formed into a tube and provided with some
sort of adhesive tape or the like 51 to hold the same assembled.
This may be easily slipped over the bookcase shown in FIG. 4 when
the front wall is closed and will be of a size to retain the books
in the bookcase and the front in its closed position.
