Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to bookcases and, in
particular, to an extendable bookcase that, when extended by the
attachment of one or more bookcase extension sections, appears to
be a single bookcase. Such extendable bookcases can be used
anywhere that modular bookcases are used as well as anywhere that
single bookcases are used. The modularity of the bookcase sections
of the instant invention facilitates their construction, shipping,
handling, and installation. A corner section may also be
included.
[0003] In its simplest form, the instant invention is an extendable
bookcase comprising a basic bookcase section and a removable
pilaster. Once the removable pilaster has been removed from the
basic bookcase section, a first bookcase extension section may be
attached to basic bookcase section. The removable pilaster may then
be attached to the first bookcase extension, thereby giving the
combined basic bookcase section and the first bookcase extension
section the appearance of a single, continuous, built-in bookcase
having two sections.
[0004] Any number of additional bookcase extension sections, each
such section attached to another such section, may be added to the
first bookcase extension section. Each bookcase extension section
has a pilaster fixedly attached at one side of each such bookcase
extension section. The opposite side of each such bookcase
extension section is configured to receive either (a) the removable
pilaster, (b) a joining pilaster of the next-attached bookcase
extension section, or (c) a joining pilaster of a corner
section.
[0005] The corner section is configured to attach to (a) the basic
bookcase section, (b) any bookcase extension section or (c) any
other corner section.
[0006] As used in this specification, application and claims, the
term "bookcase" is defined as a structure having two
vertically-oriented pieces in a side-by-side configuration and
means for directly or indirectly connecting the vertically-oriented
pieces to one another. As defined herein, a "bookcase" includes,
but is not limited to, two such vertically-oriented pieces that
have at least one of the following items located between such
vertically-oriented pieces: a shelf, a drawer, a cabinet, a door, a
bin, a joining member or joining members, a sliding member or
sliding members, a complete or partial covering or a complete or
partial panel. As used in this specification, application and
claims, the definition of the term "bookcase" includes, but is not
limited to, show cases, trophy cases, display cases, gun cases,
file cases, storage cases, safe cases, cabinets, lockers, and any
combination of any of the foregoing. "Bookcases" as defined herein
may also have or include, among other things, file storage
(legal/letter), glass and/or wood doors, lighting, hidden
compartments, (e.g., behind carvings), a bar, wine racks, glass
racks, gun storage, and electronics, (e.g., docking and/or charging
stations), "Bookcases" as defined above may be made in whole or in
part from any material including, but not limited to, one or more
of the following materials: wood, glass, metal, plastic, and any
manufactured product that includes any wood, glass, metal or
plastic.
[0007] 2. Description of the Related Art
[0008] Multiple-section bookcases that have been built as one
single, continuous bookcase are usually constructed as either a
two-section bookcase having a vertical column midway between each
end of the bookcase or a three-section bookcase having two such
vertical columns evenly spaced between the ends of the bookcase.
The extra width of the two-section bookcase and the three-section
bookcase results in corresponding extra weight and bulk. This extra
weight and bulk makes each two-section and three-section bookcase
relatively difficult to handle during shipment and
installation.
[0009] A multiple-section bookcase that has the appearance of being
one continuous bookcase after installation is disclosed in U.S.
Pat. No. 351,354 ("Bangs"). In its Figures, Bangs shows a
two-section bookcase comprising bookcase sections A and B where
section A has a pilaster on the left end and no pilaster on the
right end. Section B has a pilaster on the right end and a pilaster
C on the left end that is configured so that half of pilaster C
overlaps section B and is the other half of pilaster C overlaps
section A. When sections A and B are attached to one another as
disclosed in Bangs, they collectively have the appearance of one
continuous bookcase.
[0010] However, among other differences with respect to the instant
invention, Bangs does not have or disclose any removable pilaster
or any corner section. The instant invention also does not have or
require any bracket to attach the bookcase sections to one another.
Bangs, on the other hand, requires, discloses and claims such a
bracket.
[0011] Unlike Bangs, the presence of a removable pilaster in the
instant invention allows the instant invention to be embodied in a
single-section, extendable bookcase having a pilaster at each end.
The invention disclosed in Bangs, however, cannot be embodied in a
single bookcase section A or bookcase section B. Neither bookcase
section A nor bookcase section B of Bangs is a complete bookcase by
itself Instead, both bookcase sections A and B are required to be
present to embody the invention disclosed in Bangs.
SUMMARY OF THE INVENTION
[0012] The present invention is a an extendable bookcase comprising
a basic bookcase section having a fixed pilaster on one side and a
removable pilaster on the opposite side. The side with the fixed
pilaster is the pilaster side and, opposite thereto, is a receiving
side. A fixed pilaster is fixed to the pilaster side. The removable
pilaster is attachable to the receiving side.
[0013] A bookcase extension section is attachable to the basic
bookcase section. The bookcase extension section comprises a
joining pilaster side and, opposite thereto, a receiving side. The
bookcase extension section may be attached to the receiving side of
the basic bookcase section after the removable pilaster has been
removed. When a bookcase extension section is attached to the basic
bookcase section, the removable pilaster may then be attached to
the receiving side of the bookcase extension section. In this
manner, the basic bookcase section and the bookcase extension
section are joined together such that they appear to be one
bookcase instead of two bookcases. Any number of bookcase extension
sections may be added by removing the removable pilaster, attaching
the bookcase extension section(s), and attaching the removable
pilaster to the last-attached bookcase extension section.
[0014] To accommodate corners, a corner section is provided. When
the corner section is attached to the basic bookcase section and
the bookcase extension section(s), the appearance is one of being a
single, continuous bookcase that wraps around a corner. The corner
section is angled or curved to conform to a corner. The corner
section comprises a joining pilaster side and a receiving side. The
joining pilaster side of the corner section is attachable to the
receiving side of (a) the basic bookcase section, (b) a bookcase
extension section or (c) another corner section. The receiving side
of the corner section is attachable to (a) the joining pilaster
side of a bookcase extension section, (b) another corner section or
(c) a removable pilaster.
[0015] Any number or combination of bookcase extension sections and
corner sections may be attached to (a) the basic bookcase section,
(b) a bookcase extension section or (c) a corner section. The
removable pilaster may then be attached to the last-attached
component whether that last-attached component is a bookcase
extension section or a corner section.
[0016] The basic bookcase section, each bookcase extension section,
and each corner section can each be made in practically any width.
The corner section can be made to conform to practically any corner
or curve.

DESCRIPTION OF PREFERRED EMBODIMENT
[0029] The invention will now be described with reference to the
embodiments shown in FIGS. 1 through 11.
One-Section Embodiment
[0030] In its simplest form, the instant invention is a
single-section, extendable bookcase 10. An example of one such
single-section embodiment is shown in FIG. 1. An extendable
bookcase 10 comprises a basic bookcase section 11 and a removable
pilaster 12. As shown in FIG. 2, the basic bookcase section 11
comprises a pilaster side 13 and, opposite thereto, a receiving
side 14. A fixed pilaster 15 is fixedly attached to the pilaster
side 13. The receiving side 14 is configured to attachably receive
a removable pilaster 12. Removable pilaster 12 comprises a
removable receiving side 16 and an outer side 17. As shown in FIGS.
2 and 4, the removable receiving side 16 has four bolt holes 18a,
18b, 18c, and 18d positioned to align with four corresponding
threaded bolt holes 19a, 19b, 19c, and 19d located in the removable
receiving side 16. The particular embodiment shown in FIGS. 1
through 11 includes shelves 20a, 20b, 20c, and 20d, drawer 21,
crown molding 22, upper waist molding 32, lower waist molding 23,
and base molding 24.
[0031] In a single-section embodiment, the extendable bookcase 10
comprises basic bookcase section 11 and removable pilaster 12.
Removable pilaster 12 is attached to basic bookcase section 11 by
first positioning removable pilaster 12 so that its threaded bolt
holes 19a, 19b, 19c, and 19d align with the bolt holes 18a, 18b,
18c, and 18d in the removable receiving side 16. A bolt 25 is then
inserted through each bolt hole 18a, 18b, 18c, and 18d of the
receiving side 14 of the basic bookcase section 11 and then
threaded into each respective threaded bolt hole 19a, 19b, 19c, and
19d in the removable receiving side 16 of the removable pilaster
12. Each bolt 25 is then tightened until the removable pilaster 12
is drawn into fixed contact with the receiving side 14.
[0032] Pilaster 15 and removable pilaster 12 may have practically
any outer appearance. For example, the outer appearance of pilaster
15 and removable pilaster 12 could range from something flat,
unadorned and featureless to something like the crown molding 22,
upper waist molding 32, lower waist molding 23, and base molding 24
shown in FIG. 2 to something more ornate. The use of molding can
contribute to a seamless appearance so that multiple sections is
collectively have the appearance of being a single, continuous,
built-in-place bookcase. For example, as can be seen in FIG. 4, the
basic bookcase section 11 has a 45 degree vertical planar surface
in its crown molding 49, a 45 degree vertical planar surface in its
lower waist molding 57, and a 45 degree vertical planar surface in
its base molding 58. These 45 degree vertical planar surfaces abut
and are overlapped by, and congruent with, 45 degree vertical
planar surfaces in, respectively, the crown molding 22, lower waist
molding 23, and base molding 24 of the removable pilaster 12. This
overlapping abutment tends to cover the juncture where the
removable receiving side 16 of the removable pilaster 12 abuts the
receiving side 14 of the basic bookcase section 11. Although the
planar surfaces of each pair of overlapping moldings, i.e., 22
overlapping 49, 23 overlapping 57, and 24 overlapping 58, are each
shown to abut one another at 45 degrees and to each be vertically
oriented, the angle of each such abutment surface could instead be
an angle other than 45 degrees and the plane in which each such
abutment surface exists could be other than vertical.
[0033] The bolt 25 can be any type of bolt including, but not
limited to, a hex head bolt, an allen head bolt or a slotted pan
head bolt. In a preferred embodiment, the bolt 25 is an allen head
bolt, the head of which resides in a countersink hole in the
receiving side 14 when it is fastened to the removable pilaster 12.
The invention, however, is not limited to attachment by bolt 25.
Any attachment that fixedly holds one section or component to
another section or component is within the scope of the invention.
The threaded bolt holes 19a, 19b, 19c, and 19d typically extend
only through the removable receiving side 16 and do not extend at
all into the outer side 17 so that the outer side 17 maintains a
finished appearance. The bolts 25 are sufficiently short so as to
reach full tightness without contacting outer side 17.
Two-Section Embodiment
No Corner Section
[0034] An example of a two-section embodiment that does not have a
corner section is shown in FIG. 4. That particular two-section
embodiment comprises a basic bookcase section 11, a first bookcase
extension section 26, and a removable pilaster 12. The first
bookcase extension section 26 further comprises first joining
pilaster side 27 and, opposite thereto, a first receiving side 28,
and a first joining pilaster 29 fixedly attached to the first
joining pilaster side 27. First joining pilaster side 27 has
threaded bolt holes 30a, 30b, 30c, and 30d.
[0035] First bookcase extension section 26 is attached to basic
bookcase section 11 by first positioning first bookcase extension
section 26 so that its threaded bolt holes 30a, 30b, 30c, and 30d
in its first joining pilaster side 27 align with the bolt holes
18a, 18b, 18c, and 18d in the receiving side 14 of the basic
bookcase section 11. A bolt 25 is then inserted through each bolt
hole 18a, 18b, 18c, and 18d of the receiving side 14 and then
threaded into each respective threaded bolt hole 30a, 30b, 30c, and
30d in the first joining pilaster side 27. Each bolt 25 is then
tightened until the first joining pilaster side 27 is drawn into
fixed contact with the receiving side 14.
[0036] Removable pilaster 12 is attached to first receiving side 28
of first bookcase extension section 26 by first positioning
removable pilaster 12 so that its threaded bolt holes 19a, 19b,
19c, and 19d align with the bolt holes 31a, 31b, 31c, and 31d in
the first receiving side 28. A bolt 25 is then inserted through
each bolt hole 31a, 31b, 31c, and 31d of the first receiving side
28 and then threaded into each respective threaded bolt hole 19a,
19b, 19c, and 19d in the removable receiving side 16 of removable
pilaster 12. Each bolt 25 is then tightened until the removable
receiving side 16 of the removable pilaster 12 is drawn into fixed
contact with the first receiving side 28.
[0037] The particular embodiment of first bookcase extension
section 26 shown in FIG. 4 includes first crown molding 45, first
upper waist molding 46, first lower waist molding 47, and first
base molding 48.
[0038] First joining pilaster 29 may have practically any outer
appearance. For example, the outer appearance of first joining
pilaster 29 could range from something flat, unadorned and
featureless to something like the first crown molding 45, first
upper waist molding 46, first lower waist molding 47, and first
base molding 48 shown in FIG. 4 to something more ornate. The use
of molding can contribute to a seamless appearance so that multiple
sections collectively have the appearance of being a single,
continuous, built-in-place bookcase. For example, as can be seen in
FIG. 4, the basic bookcase section 11 has a 45 degree vertical
planar surface in its crown molding 49, a 45 degree vertical planar
surface in its lower waist molding 57, and a 45 degree vertical
planar surface in its base molding 58. These 45 degree vertical
planar surfaces abut and are overlapped by and congruent with, 45
degree vertical planar surfaces in, respectively, the first crown
molding 45, first lower waist molding 47, and first base molding 48
of the first joining pilaster 29. This overlapping abutment tends
to cover the juncture where the first joining pilaster side 27
abuts the receiving side 14 of the basic bookcase section 11.
Although the planar surfaces of each pair of overlapping moldings,
i.e., 45 overlapping 49, 47 overlapping 57, and 48 overlapping 58,
are each shown to abut one another at 45 degrees and to each be
vertically oriented, the angle of each such abutment surface could
instead be an angle other than 45 degrees and the plane in which
each such abutment surface exists could be other than vertical.
Three-or-More-Section Embodiment
No Corner Section
[0039] An example of a three-section embodiment that does not have
a corner section is shown in FIG. 3. That particular three-section
embodiment comprises a basic bookcase section 11, a first bookcase
extension section 26, a second bookcase extension section 40, and a
removable pilaster 12. The second bookcase extension section 40
further comprises second joining pilaster side 41 and, opposite
thereto, a second receiving side 42, and a second joining pilaster
43 fixedly attached to the second joining pilaster side 41. Second
joining pilaster side 41 has threaded bolt holes 44a, 44b, 44c, and
44d.
[0040] Second bookcase extension section 40 is attached to first
bookcase extension section 26 by first positioning second bookcase
extension section 40 so that its threaded bolt holes 44a, 44b, 44c,
and 44d in its second joining pilaster side 41 align with the bolt
holes 31a, 31b, 31c, and 31d in the first receiving side 28 of the
first bookcase extension section 26 shown in FIG. 4. A bolt 25 is
then inserted through each bolt hole 31a, 31b, 31c, and 31d of the
first receiving side 28 and then threaded into each respective
threaded bolt hole 44a, 44b, 44c, and 44d in the second joining
pilaster side 41. Each bolt 25 is then tightened until the second
joining pilaster side 41 is drawn into fixed contact with the first
receiving side 28.
[0041] Removable pilaster 12 is attached to second receiving side
42 of second bookcase extension section 40 by first positioning
removable pilaster 12 so that its threaded bolt holes 19a, 19b,
19c, and 19d align with the bolt holes 44a, 44b, 44c, and 44d in
the second receiving side 42. A bolt 25 is then inserted through
each bolt hole 44a, 44b, 44c, and 44d of the second receiving side
42 and then threaded into each respective threaded bolt hole 19a,
19b, 19c, and 19d in the removable pilaster 12 as shown in FIG. 2.
Each bolt 25 is then tightened until the removable pilaster 12 is
drawn into fixed contact with the second receiving side 42.
[0042] In an embodiment have four or more sections, e.g., a basic
bookcase section 11 and three or more bookcase extension sections
26, 40, 60, 70 and no corner section 50, each successive bookcase
extension section is attached to one another in the same manner as
described above for attaching second bookcase extension section 40
to first bookcase extension section 26. After the desired number of
bookcase extension sections is attached in this manner, the
removable pilaster 12 is attached to the last-attached bookcase
extension section in the same manner that the removable pilaster
was attached to the second bookcase extension section 40.
Corner Section Embodiment
[0043] An example of an embodiment of the instant invention that
includes a corner section is shown in FIGS. 8, 9, 10, and 11. In
its simplest form, a an embodiment of the instant invention that
includes a corner section comprises a basic bookcase section 11, a
corner section 50, and a removable pilaster 12. The corner section
50 further comprises a joining pilaster side 51, a receiving side
52 oriented across therefrom, and a joining pilaster 53 fixedly
attached to the joining pilaster side 51. Joining pilaster side 51
has threaded bolt holes 54a and 54b. Receiving side 52 has bolt
holes 55a and 55b.
[0044] Corner section 50 is attached to basic bookcase section 11
by first positioning corner section 50 so that its threaded bolt
holes 54a and 54b in its joining pilaster side 51 align with the
bolt holes 18a and 18b in the receiving side 14 of the basic
bookcase section 11 in a manner similar to that shown in FIG. 4. A
bolt 25 is then inserted through each bolt hole 18a and 18b of the
receiving side 14 and then threaded into each respective threaded
bolt hole 54a and 54b in the joining pilaster side 51. Each bolt 25
is then tightened until the joining pilaster side 51 is drawn into
fixed contact with the receiving side 14.
[0045] Removable pilaster 12 is attached to receiving side 52 of
corner section 50 by first positioning removable pilaster 12 so
that its threaded bolt holes 19a and 19b align with the bolt holes
55a and 55b in the receiving side 52. A bolt 25 is then inserted
through each bolt hole 55a and 55b of the receiving side 52 and
then threaded into each respective threaded bolt hole 19a and 19b
in the removable pilaster 12. Each bolt 25 is then tightened until
the removable receiving side 16 of the removable pilaster 12 is
drawn into fixed contact with the receiving side 52.
[0046] The particular corner section shown in FIGS. 8, 9, 10, and
11 includes corner crown molding 80, corner upper waist molding 82,
corner lower waist molding 83, and corner base molding 84.
[0047] Joining pilaster 53 may have practically any outer
appearance. For example, the outer appearance of joining pilaster
53 could range from something flat, unadorned and featureless to
something like the corner crown molding 80, corner upper waist
molding 82, corner lower waist molding 83, and corner base molding
84 shown in FIG. 11 to something more ornate. The use of molding
can contribute to a seamless appearance so that multiple sections
collectively have the appearance of being a single, continuous,
built-in-place bookcase. For example, as can be seen in FIG. 4, the
basic bookcase section 11 has a 45 degree vertical planar surface
in its crown molding 49, a 45 degree vertical planar surface in its
lower waist molding 57, and a 45 degree vertical planar surface in
its base molding 58. These 45 degree vertical planar surfaces abut
and are overlapped by, and congruent with, 45 degree vertical
planar surfaces in, respectively, the corner crown molding 80, the
corner lower waist molding 83, and the corner base molding 84 of
the joining pilaster 53. This overlapping abutment tends to cover
the juncture where the joining pilaster side 53 of the corner
section 50 abuts the receiving side 14 of the basic bookcase
section 11. Although the planar surfaces of each pair of
overlapping moldings, i.e., 80 overlapping 49, 83 overlapping 57,
and 84 overlapping 58, are each shown to abut one another at 45
degrees and to each be vertically oriented, the angle of each such
abutment surface could instead be an angle other than 45 degrees
and the plane in which each such abutment surface exists could be
other than vertical.
[0048] As indicated in FIGS. 8, 9, 10, and 11, bookcase extension
sections 26, 40 can be attached to basic bookcase section 11 before
attaching the corner section 50 to the last such attached bookcase
extension section. As also indicated in FIGS. 8, 9, 10, and 11,
bookcase extension sections 60, 70 can be attached to the receiving
side 52 of the corner section 50 before attaching the removable
pilaster 12 to the last such attached bookcase extension section
70.
[0049] In addition to the particular embodiment shown in FIGS. 8,
9, 10, and 11, other embodiments of the instant invention may
include a basic bookcase section 11 attached to one bookcase
extension section 26 or, alternatively, to any number or bookcase
extension sections 26, 40, 60, 70, et seq. Still other embodiments
of the instant invention may include a basic bookcase section 11
attached to one corner section 50 or, alternatively, to any number
of corner sections 50, et seq. Two additional embodiments of the
instant invention are (1) a basic bookcase section 11 attached to a
bookcase extension section 26 which, in turn, is attached to a
corner section 50 and (2) a basic bookcase section 11 attached to a
corner section 50 which, in turn, is attached to a bookcase
extension section 26. Still other embodiments of the instant
invention may include a basic bookcase section 11 attached to one
or more bookcase extension sections 26 et seq. in combination with
one or more corner sections 50 et seq. In all of the foregoing
embodiments, the removable pilaster 12 may then be attached to the
last-attached component whether that last-attached component is a
bookcase extension section or a corner section.
[0050] The corner section 50 can be made having any angle necessary
to conform to any corner. The corner section 50 can also be made in
a convex or concave curved manner to conform to any rounded
corners. The corner section 50 can also be made to accommodate
corners greater than 90 degrees such as, for example, a 270 degree
corner.
[0051] A ladder rail may be added to the extendable bookcase to
provide a stable support for a ladder.
[0052] Although all of the embodiments shown in FIGS. 1-11 have a
pilaster fixed on the left-hand side of each section and a
receiving side on the right-hand side of each section, the
extendable bookcase also includes embodiments having a pilaster
fixed on the right-hand side of each section and the left-hand side
being the receiving side.
[0053] While the foregoing detailed description sets forth a number
of embodiments of an extendable bookcase in accordance with the
present invention, the above description is illustrative only and
not limiting of the disclosed invention.
