DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
Referring to FIGS. 1-6, a bookcase 100 suitable for use as, or conversion to, a table having a work surface is shown. The bookcase 100 includes a substantially cuboidal structure having a top panel 102, four sides 104, 106, 108, 110 extending downwardly from the top panel 102 and defining four vertically extending corners 112, and a bottom or a base 114. As shown, the bookcase 100 includes four corner cabinets 116 arranged along the four corners 112 of the bookcase 100. Each of the corner cabinets 116 is identical in construction and includes a first wall 118, a second wall 120 connected to the first wall 118 and defining a space 122 therebetween. As seen throughout the drawings, the first wall 118 and the second wall 120 are angled with respect to one another, and the first wall 118 and the second wall 120 are adjacent along a respective pair of sides. The first wall 118 and the second wall 120 are angled to extend away from one another. Preferably the first wall 118 and the second wall 120 may be oriented or angled perpendicular to one another. And even more so, the first wall 118 may be parallel to a rear wall 136 of a first adjacent side cabinet 130, while the second wall 120 may be parallel to a rear wall 136 of a second adjacent side cabinet 130. Each corner cabinet 116 includes a plurality of corner shelves 124 arranged inside the space 122 and between the base 114 and the top panel 102. In an embodiment, each corner shelf 124 includes a shape of a sector of a circle and is connected to and supported by the first wall 118 and the second wall 120. It may be appreciated that one of the corner shelves 124 is a bottom shelf 126 which is defined by a portion of the base 114 and is integrally formed with the base 114. Each corner shelf 124 of each of the corner cabinets 116 is engaged or supported via a plurality of shelf pins (not shown). In some embodiments, the bottom shelf 126 may be connected to and supported by the base 114 via a bracket (not shown) connected to the base 114.
The bookcase 100 also includes a plurality of side cabinets 130 which are preferably arranged on four sides 104, 106, 108, 110 of the bookcase 100. Each side cabinet 130 includes a compartment 132 defined between two adjacent corner cabinets 116, and a plurality of side shelves 134 arrayed vertically inside the compartment 132. The side shelves 134 are connected to the first wall 118 of the one corner cabinet 116 and the second wall 120 of the adjacent corner cabinet 116. Further, each side shelf 134 may be connected/engaged with a rear wall 136 of the side the cabinet 130. One of the side shelves 134 is a bottom shelf 135.
In an embodiment, as shown in FIGS. 1 to 3, the side shelves 134 may be removably arranged inside the compartment 132 and may be removed from the compartment 132 when needed. The side shelves 134 may be removed to provide leg space 140 for a user sitting on a chair and using the bookcase 100 as a table.
In another embodiment, as shown in FIGS. 4 and 5, each of the side shelves 134 is pivotally connected to the rear wall 136 of the side cabinet 130 and is adapted to move between a lowered position (shown in FIG. 4) and a stored position (shown in FIG. 5). In the lowered position, the side shelf 134 is arranged substantially horizontally and facilitates positioning or storing of books upon the side shelf 134. In the stored position, the side shelf 134 is arranged substantially parallel to the rear wall 136 and abutting the rear wall 136 to provide the leg space 140 for a person sitting on a chair and using the top panel 102 as the work surface. In an embodiment, the rear wall 136 of each side cabinet 130 extends vertically from the base 114 to the top panel 102 and is arranged inwardly of an outer edge 142 of the top panel 102.
Furthermore, the bookcase 100 includes a plurality of castors 150 connected to the base 114 and supporting the bookcase 100 on a ground surface. The castors 150 allow movement of the bookcase 100 from one location to another. In an embodiment, one or more castor 150 includes a brake to prevent the castor 150 from rolling, and hence preventing the movement of the bookcase 100 on the ground.
As shown in FIGS. 2 and 3, the rear walls 136 of the four cabinets 130 defines a storage compartment 152 therebetween. The storage compartment 152 extends from the base 114 to the top panel 102 and is located centrally within the bookcase 100. The top panel 102 defines an access opening 154 (shown in FIG. 6) of the storage compartment 152. The access opening 154 is located substantially centrally to the top panel 102.
The bookcase 100 is preferably formed by assembling two identical half portions 160, 162, in which two of the rear walls 136, the base 114, and the top panel 102, each are formed by assembling two half panels. In an embodiment, the top panel 102 is a single panel and the bookcase 100 is split into two half portions 160, 162 by removing the top panel 102. Preferably each of the half portions 160, 162 includes three castors 150, two arranged below the bottom shelves 126 of the two corner cabinets 116, and one castor 150 arranged below and substantially centrally to the partition wall 168. Although not shown in the drawings, four castors 150 may be provided, with each castor 150 being positioned near a corner of the half panel. As shown in FIGS. 2 and 3, the storage compartment 152 includes a first storage bin 164 and a second storage bin 166 separated from the first storage bin 164 by a partition wall 168. The partition wall 168 may be formed by two panels 170, 172 abutting each other and extending vertically from the base 114 towards the top panel 102. In the assembly of two half portions 160, 162, the partition wall 168 is arranged substantially centrally to the storage compartment 152. As shown, a first panel 170 of the partition wall 168 is attached to a first half portion 160, while a second panel 172 of the partition wall 168 is attached to a second half portion 162. In some embodiments, the partition wall 168 may be omitted.
Furthermore, the bookcase 100 includes a cover 180 engaged with the top panel 102 and adapted to cover the access opening 154. Preferably, the cover 180 is engaged with the top panel 102 such that an upper surface of the cover 180 is flush and aligned with an upper surface of the top panel 102 when the cover 180 is arranged to cover the access opening 154. The bookcase 100 preferably includes at least one tray 181 (shown in FIG. 6) arranged inside the storage compartment 152 and arranged proximate to the access opening 154 to store various articles. The tray 181 is preferably generally rectangular in shape and has a bottom surface 184, a plurality of walls 185 extending upward therefrom, and an open top that allows free access into the tray 181. The tray 181 also preferably has a lip 186 that is located at a top edge of the walls 185 and the lip 186 extends outwardly therefrom. The lip 186 preferably extends around the perimeter of the top edge of the tray 181. To allow the insertion and positioning of the at least one tray 181 inside the storage compartment 152, the lip 186 can be positioned atop, and supported by, a top edge of the rear walls 136 and the partition wall 168. Furthermore, the top edge of the rear walls 136 and the partition wall 168 may be sufficiently recessed below the top panel 102 (thereby lowering the tray 181 as needed) so that the cover 180 over the access opening 154 is flush with the top panel 102. The storage bins 164, 166 and the trays 181 may also be separated from each other via horizontally arranged panels 183. The tray 181 can be removed from the bookcase 100 and may be carried elsewhere in the room. Also, the bookcase 100 may be used as the table with the cover 180 removed from the bookcase 100 to facilitate an easy access of the items stored inside the tray 181 to a user. In an embodiment, the cover 180 may be positioned covering the access opening 154 to provide extra working space when the top panel 102, and hence the bookcase 100 is being used as the table.
In yet another embodiment, as shown in FIGS. 7-9, each of the side shelves 134 are removable from the side wall 136 of the side cabinet 130 and are adapted to move between a lowered position (shown in FIG. 7) and a stored position (shown in FIG. 9). In the lowered position, the side shelf 134 is arranged substantially horizontally and facilitates positioning or storing of books upon the side shelf 134. In the stored position, the side shelf 134 is arranged substantially parallel to the side wall 136 and adjacent to, but spaced apart from, the side wall 136 to provide the leg space 140 for a person sitting on a chair and using the top panel 102 as the work surface.
According to this embodiment, the rear wall 136 includes a plurality of magnets 188 which are secured to, and preferably flush with, the rear wall 136. Even more preferably, the rear wall 136 includes holes having a shape that is complementary to the magnets 188 so that the magnets 188 can be imbedded or secured therein. Shown in FIG. 8 is an embodiment of the side shelf 134 as depicted in FIGS. 7 and 9. A bottom surface 190 of the side shelf 134 includes spacers 192 which extend outward from the bottom surface 190. The spacers 192 also include holes having a shape that is complementary to the magnets 188 so that the magnets 188 can also be imbedded or secured therein. Alternatively, the magnets 188 can be secured directly to, or imbedded within, the bottom surface 190 of the side shelf 134. Importantly, the magnets 188 in the rear wall 136 align with the magnets 188 in the side shelf 134 so that the side shelf 134 can be secured in place while in the stored position due to the magnets' attractive polarity. The spacers 192 are preferably included because the spacers 192 function to space the side shelf 134 from the rear wall 136. The resulting gap between the rear wall 136 and the side shelf 134 provides a gripping location for a user to secure the side shelf 134 when the side shelf 134 is placed into or removed from the stored position.
In use, a user grasps the side shelf 134 in the lowered position shown in FIG. 7. The user then pivots the side shelf 134 so that the rear edge 192 slides upward along the rear wall 136, while the front edge 184 is angled toward the rear wall 136. The magnets 188 in the side shelf 134 are aligned with the magnets 188 in the rear wall 136, and the side shelf 134 is thereby secured into the stored position. That process is then reversed when a user desires to move the side shelf 136 from the stored position to the lowered position. And as mentioned above, the spacers 192 provide a gap between the side shelf 134 and the rear wall 136 which aids the user in quickly and easily grasping the side shelf 134.
It should be understood that the foregoing description is only illustrative of the aspects of the disclosed embodiments. Various alternatives and modifications can be devised by those skilled in the art without departing from the aspects of the disclosed embodiments. Accordingly, the aspects of the disclosed embodiments are intended to embrace all such alternatives, modifications, and variances that fall within the scope of the appended specification.
