Description
- 1. Field of the Invention
- 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.
- 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.
- 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.
- The corner section is configured to attach to (a) the basic bookcase section, (b) any bookcase extension section or (c) any other corner section.
- 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.
- 2. Description of the Related Art
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.

FIGS. 1 through 11 . - In its simplest form, the instant invention is a single-section,
extendable bookcase 10. An example of one such single-section embodiment is shown inFIG. 1 . Anextendable bookcase 10 comprises abasic bookcase section 11 and aremovable pilaster 12. As shown inFIG. 2 , thebasic bookcase section 11 comprises apilaster side 13 and, opposite thereto, a receivingside 14. A fixedpilaster 15 is fixedly attached to thepilaster side 13. The receivingside 14 is configured to attachably receive aremovable pilaster 12.Removable pilaster 12 comprises a removable receivingside 16 and anouter side 17. As shown inFIGS. 2 and 4 , the removable receivingside 16 has fourbolt holes side 16. The particular embodiment shown inFIGS. 1 through 11 includesshelves drawer 21,crown molding 22,upper waist molding 32,lower waist molding 23, andbase molding 24. - In a single-section embodiment, the
extendable bookcase 10 comprisesbasic bookcase section 11 andremovable pilaster 12.Removable pilaster 12 is attached tobasic bookcase section 11 by first positioningremovable pilaster 12 so that its threaded bolt holes 19 a, 19 b, 19 c, and 19 d align with the bolt holes 18 a, 18 b, 18 c, and 18 d in the removable receivingside 16. Abolt 25 is then inserted through eachbolt hole side 14 of thebasic bookcase section 11 and then threaded into each respective threadedbolt hole side 16 of theremovable pilaster 12. Eachbolt 25 is then tightened until theremovable pilaster 12 is drawn into fixed contact with the receivingside 14. -
Pilaster 15 andremovable pilaster 12 may have practically any outer appearance. For example, the outer appearance ofpilaster 15 andremovable pilaster 12 could range from something flat, unadorned and featureless to something like thecrown molding 22,upper waist molding 32,lower waist molding 23, andbase molding 24 shown inFIG. 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 inFIG. 4 , thebasic bookcase section 11 has a 45 degree vertical planar surface in itscrown molding 49, a 45 degree vertical planar surface in itslower waist molding 57, and a 45 degree vertical planar surface in itsbase molding 58. These 45 degree vertical planar surfaces abut and are overlapped by, and congruent with, 45 degree vertical planar surfaces in, respectively, thecrown molding 22,lower waist molding 23, andbase molding 24 of theremovable pilaster 12. This overlapping abutment tends to cover the juncture where the removable receivingside 16 of theremovable pilaster 12 abuts the receivingside 14 of thebasic 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. - 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, thebolt 25 is an allen head bolt, the head of which resides in a countersink hole in the receivingside 14 when it is fastened to theremovable pilaster 12. The invention, however, is not limited to attachment bybolt 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 19 a, 19 b, 19 c, and 19 d typically extend only through the removable receivingside 16 and do not extend at all into theouter side 17 so that theouter side 17 maintains a finished appearance. Thebolts 25 are sufficiently short so as to reach full tightness without contactingouter side 17. - 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 abasic bookcase section 11, a firstbookcase extension section 26, and aremovable pilaster 12. The firstbookcase extension section 26 further comprises first joiningpilaster side 27 and, opposite thereto, a first receivingside 28, and a first joiningpilaster 29 fixedly attached to the first joiningpilaster side 27. First joiningpilaster side 27 has threaded bolt holes 30 a, 30 b, 30 c, and 30 d. - First
bookcase extension section 26 is attached tobasic bookcase section 11 by first positioning firstbookcase extension section 26 so that its threaded bolt holes 30 a, 30 b, 30 c, and 30 d in its first joiningpilaster side 27 align with the bolt holes 18 a, 18 b, 18 c, and 18 d in the receivingside 14 of thebasic bookcase section 11. Abolt 25 is then inserted through eachbolt hole side 14 and then threaded into each respective threadedbolt hole pilaster side 27. Eachbolt 25 is then tightened until the first joiningpilaster side 27 is drawn into fixed contact with the receivingside 14. -
Removable pilaster 12 is attached to first receivingside 28 of firstbookcase extension section 26 by first positioningremovable pilaster 12 so that its threaded bolt holes 19 a, 19 b, 19 c, and 19 d align with the bolt holes 31 a, 31 b, 31 c, and 31 d in the first receivingside 28. Abolt 25 is then inserted through eachbolt hole side 28 and then threaded into each respective threadedbolt hole side 16 ofremovable pilaster 12. Eachbolt 25 is then tightened until the removable receivingside 16 of theremovable pilaster 12 is drawn into fixed contact with the first receivingside 28. - The particular embodiment of first

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 inFIG. 4 , thebasic bookcase section 11 has a 45 degree vertical planar surface in itscrown molding 49, a 45 degree vertical planar surface in itslower waist molding 57, and a 45 degree vertical planar surface in itsbase molding 58. These 45 degree vertical planar surfaces abut and are overlapped by and congruent with, 45 degree vertical planar surfaces in, respectively, thefirst crown molding 45, first lower waist molding 47, andfirst base molding 48 of the first joiningpilaster 29. This overlapping abutment tends to cover the juncture where the first joiningpilaster side 27 abuts the receivingside 14 of thebasic 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. - 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 abasic bookcase section 11, a firstbookcase extension section 26, a secondbookcase extension section 40, and aremovable pilaster 12. The secondbookcase extension section 40 further comprises second joiningpilaster side 41 and, opposite thereto, a second receivingside 42, and a second joiningpilaster 43 fixedly attached to the second joiningpilaster side 41. Second joiningpilaster side 41 has threaded bolt holes 44 a, 44 b, 44 c, and 44 d. - Second

Abolt 25 is then inserted through eachbolt hole side 28 and then threaded into each respective threadedbolt hole pilaster side 41. Eachbolt 25 is then tightened until the second joiningpilaster side 41 is drawn into fixed contact with the first receivingside 28. -
Removable pilaster 12 is attached to second receivingside 42 of secondbookcase extension section 40 by first positioningremovable pilaster 12 so that its threaded bolt holes 19 a, 19 b, 19 c, and 19 d align with the bolt holes 44 a, 44 b, 44 c, and 44 d in the second receivingside 42. Abolt 25 is then inserted through eachbolt hole side 42 and then threaded into each respective threadedbolt hole removable pilaster 12 as shown inFIG. 2 . Eachbolt 25 is then tightened until theremovable pilaster 12 is drawn into fixed contact with the second receivingside 42. - In an embodiment have four or more sections, e.g., a
basic bookcase section 11 and three or morebookcase extension sections corner section 50, each successive bookcase extension section is attached to one another in the same manner as described above for attaching secondbookcase extension section 40 to firstbookcase extension section 26. After the desired number of bookcase extension sections is attached in this manner, theremovable pilaster 12 is attached to the last-attached bookcase extension section in the same manner that the removable pilaster was attached to the secondbookcase extension section 40. - 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 abasic bookcase section 11, acorner section 50, and aremovable pilaster 12. Thecorner section 50 further comprises a joiningpilaster side 51, a receivingside 52 oriented across therefrom, and a joiningpilaster 53 fixedly attached to the joiningpilaster side 51. Joiningpilaster side 51 has threaded bolt holes 54 a and 54 b. Receivingside 52 has bolt holes 55 a and 55 b. -
Corner section 50 is attached tobasic bookcase section 11 by firstpositioning corner section 50 so that its threaded bolt holes 54 a and 54 b in its joiningpilaster side 51 align with the bolt holes 18 a and 18 b in the receivingside 14 of thebasic bookcase section 11 in a manner similar to that shown inFIG. 4 . Abolt 25 is then inserted through eachbolt hole side 14 and then threaded into each respective threadedbolt hole 54 a and 54 b in the joiningpilaster side 51. Eachbolt 25 is then tightened until the joiningpilaster side 51 is drawn into fixed contact with the receivingside 14. -
Removable pilaster 12 is attached to receivingside 52 ofcorner section 50 by first positioningremovable pilaster 12 so that its threaded bolt holes 19 a and 19 b align with the bolt holes 55 a and 55 b in the receivingside 52.
