Abstract
A modular display unit that may be assembled without tools and without attachment hardware includes two or more shelves having spaced-apart elongate apertures, and two or more pairs of upright members. Each of the pairs of upright members extend through two or more of the elongate apertures. The upright members may include notches or other features that are configured to engage the associated shelf. One or more wedges extend through the elongate apertures between each of the pairs of upright members, and urge the upright members against the shelf. Optionally, one or more dowels slidably engage apertures in the shelves to provide a back support for display items. The shelves may optionally include a longitudinal groove along an upper surface to support display items such as compact and/or digital video disk cases.
Description
- Display units, including, for example, bookshelves, picture display cases, display units for digital media disks, knick-knacks, and the like, are considered an essential furnishing in many homes. The modular display units are typically an aesthetic fixture in the home.
- Often it is desirable to have a display unit that covers a significant portion of a wall, for example. However, a user may desire to change the location or configuration of a display unit, for example, when remodeling or repositioning furnishings in a room, to accommodate new items, or simply to change the aesthetics in a room.
- It can be difficult, however to find a display unit that is suitably sized and shaped for a particular room or location in a room. It can also be difficult or impossible to move a particular large display unit into a particular room.
- Of course, many self-assembleable display units are available, wherein a user can bring a disassembled unit to the desired location and assemble it in place. Typically, such self-assembleable display units are put together with attachment hardware such as screws, nails, glues, brackets, and the like, and are intended to be assembled in a single, specific configuration. Particular tools may be required to assembly the unit, and the process may be difficult and time consuming. Such display units may be difficult or virtually impossible to disassemble and reassemble, for example, if it is desired to relocate it to a different room or building.
- Moreover, many users may not like the aesthetic appearance of a display unit that is held together with conventional hardware.
- There is a need for a modular display unit that may be assembled without tools, that does not require attachment hardware. It would further be advantageous to have a modular display unit that may be assembled in different configurations.
- This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This summary is not intended to identify key features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
- A modular display unit, such as a book shelf or the like, that may be assembled without tools, and may, for example, comprise a single material type such as wood, is disclosed and includes a plurality of upright supports that engage a plurality of shelves through apertures formed in the shelves. Wedges, or other biasing members, are inserted into the shelf apertures to bias the associated upright support against associated shelf. In an exemplary embodiment, the entire unit comprises wood, and may be assembled, disassembled, and reassembled, perhaps in a large number of different configurations, without the use of any tools.
- In a particular embodiment, the plurality of upright supports are configured as a pair of spaced-apart, upright members, and the wedges are disposed in the corresponding apertures between the pair of upright members.
- In a particular embodiment, the plurality of upright supports each define a wedge-shaped protrusion that is positioned to extend into one of the plurality of shelf apertures when the modular display unit is assembled, and the wedges slidably engage the wedge-shaped protrusion.
- In another particular embodiment, the wedges comprise pairs of wedges, and the plurality of pairs of wedges cooperatively bias the associated upright support against the plurality of shelves.
- In a particular embodiment, the upright supports have notches, for example, rectangular or rounded notches, that are configured to engage one of the plurality of shelves when the modular display unit is assembled.
- In particular embodiments, the plurality of upright supports are of differing lengths, and/or the shelves have differing lengths.
- In a particular embodiment, the shelves further comprise a plurality of apertures, and a plurality of dowels are provided that frictionally engage the shelf apertures.
- The foregoing aspects and many of the attendant advantages of this invention will become more readily appreciated as the same become better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:

upright members 11 are inserted into therectangular aperture 17 of thelower shelf 13, with thenotches 15 oriented outwardly. Theupright members 11 are positioned such that thelower notches 15 are aligned with thelower shelf 13, and are then pushed outwardly so that thenotches 15 slidably engage thelower shelf 13. One or more additional shelves, in this case theupper shelf 13′, may then be similarly positioned to engage theupright members 11 in spaced relation to thelower shelf 13. A first single taperedwedge 23 is inserted into therectangular aperture 17, positioned between theupright members 11 with the relatively widefirst end 37 oriented downwardly. A second single taperedwedge 23 is slidably inserted into the sameelongate aperture 17, such that theangled side 43 of the firstsingle taper wedge 23 slidably engages theangled side 43 of the secondsingle taper wedge 23, as illustrated in the detail assembly view ofFIG. 4 . Before the first andsecond wedges 23 are fully secured, a second pair ofsingle taper wedges 23 are positioned in like manner between theupright members 11 in the correspondingrectangular aperture 17 in thesecond shelf 13′. For each of the pairs ofwedges 23, urging the twosingle taper wedges 23 in opposite directions, as indicate by the arrows inFIG. 4 , will urge theupright members 11 apart, such that thenotches 15 securely engage the correspondingshelves 13. - It will be appreciated that if more than two
shelves wedges 23 may not be required at each shelf position. The pairs of tapered wedges may be provided betweenupright members 11 at any two vertical locations wherein the rigidity of theupright members 11 is sufficient to ensure all of the shelves will suitably engage theupright members 11. - Similarly, a second pair of
upright members 11 may then be positioned in the otherrectangular aperture 17 of theshelves single taper wedges 23 inserted between theupright members 11 to secure the second pair ofupright members 11 to thelower shelf 13. If theoptional dowels 25 are desired, one ormore dowels 25 are inserted into thecircular apertures 19 in theshelf 13 and positioned to slidably engage thecircular apertures 19 in the lower andupper shelves module display unit 100 with thesingle taper wedges 23 loosely installed, such that theunit 100 retains some flexibility, and when all of the components are in position, then securely engage thewedges 23 to urge theupright members 11 outwardly with some force, such that the assembledunit 100 becomes very stable and relatively rigid. - It will now be appreciated that with very few components, and without any tools or attachment hardware, the
modular display unit 100 can be easily assembled to erect the very stable unit shown inFIG. 1 . - The components of the
modular display unit 100 may be formed from any suitable material, either natural or man made. In a current embodiment the components are formed from wood, providing an attractive, all-wood display unit with no fittings, glue, nail, screws or other hardware required. -
FIG. 5 is a perspective view of a second embodiment of amodular display unit 110 in accordance with the present invention. The second embodiment shares many of the features of themodular display unit 100 described above and shown inFIG. 1 , and such common details will not be repeated, for brevity. - In the
modular display unit 110,upright members 53 include an integral angled portion, and onedouble taper wedge 53 is provided between the upright members 51 (in each of therectangular slots 17 in theshelves 13′). Refer now also toFIG. 6A , which shows anupright member 51 in isolation, andFIG. 6B , which shows adouble taper wedge 53 in isolation. Theupright member 51 includes spacednotches 55 along one long edge that are sized and shaped to engage theshelves 13′, as described above. In this embodiment, theupright member 51 also includes a wedge-shapedprotrusion 52 located generally opposite each of thenotches 55. - The
double taper wedge 53 is generally trapezoidal in shape with oppositelong sides 56 tapering inwardly from awide end 57 towards anarrow end 58. Of course, the double taper wedge may be shaped differently, for example, in a triangular or diamond shape, with curved end edges, or the like. The shape of thedouble taper wedge 53 is designed to be complementary to the wedge-shapedprotrusions 52 of theupright members 51. - Referring now again to
FIG. 5 , during assembly one of thedouble taper wedges 53 is inserted between the wedge-shapedprotrusions 52 of theupright members 51 at each of the locations shown. It will be appreciated that this second embodiment has the advantage of requiring fewer total pieces and is therefore easier to assembly. Also, when assembled as shown inFIG. 5 , thedouble taper wedges 53 cannot be disengaged from the assembled unit by a downward force. -
FIG. 9 is a perspective view of a third embodiment of amodular display unit 120 in accordance with the present invention. This third embodiment shares many of the features of themodular display unit 110 described above and shown inFIG. 5 , and such common details will not be repeated, for brevity. - The
modular display unit 120 includesupright members 51 that may be generally the same as the correspondingupright members 51 shown inFIG. 5 , wherein the width of theupright members 51 is only slightly less than the width of therectangular apertures 17 in theshelves 13′ (for example, theupright members 51 may be dimensioned wider, therectangular apertures 17 may be shorter, etc.). - In this embodiment, a
single upright member 51 extends through eachrectangular aperture 17 in theshelves 13′. Theupright members 51 are formed with wedge-shapedprotrusions 52 as described above and shown inFIG. 6A . Asingle taper wedge 23 is used to lock theupright members 11 with theshelves 13′, as discussed above. - The
modular display units FIGS. 1 , 5 and 9 respectively are relatively simple, and comprise components wherein each of the different component types is identically sized (i.e., theupright members 11 are identical, theshelves shelves rectangular slots 17. Similarly, theupright members notches -
FIG. 7A illustrates a front view of amodular display unit 120 in accordance with the present invention, which includes ashort shelf 13A, four intermediate-length shelves 13B, and a long shelf 13C. Theshelves upright members 11A (only front member visible for all upright members), a first pair of intermediate-lengthupright members 11B, a second pair of intermediate-lengthupright members 11C, and a pair oflong upright members 11D. In this embodiment, theintermediate length shelves 13B have three spaced rectangular apertures (not visible), and the long shelf 13C has four rectangular apertures. Thelong upright members 11D, for example, will have six notches for engaging the shelves. Of course, not visible in the front view ofFIG. 7A are the wedge members (23 or 53) that are disposed between corresponding upright members, as described above. - In this embodiment, the
modular display unit 120 may be provided with additional support, for example, by attachment to a wall, placement in a corner to abut a wall (e.g., to the right inFIG. 7A ), or the like. It will be appreciated that the wedge members (e.g., 23 or 53) produce a very secure assembly wherein the shelves and upright members tightly engage. - A front view of another assembled
modular display unit 130 in accordance with the present invention is shown inFIG. 7B , and comprises fourlong shelves 13D and fourshort shelves 13D, with four pairs oflong upright members 11D, and two pairs of shortupright members 11A. It will be appreciated by comparingFIG. 7A with 7B, which use some of the same components, that with a relatively small number of different sized components a huge variety of modular display units may be constructed. - The upright members described above have generally rectangular notches that are sized to slidably receive a corresponding shelf. However, it will be appreciated by persons of skill in the art that the wedge members produce an outward force on the upright members, such that the upright members may be firmly biased against the corresponding shelf. The magnitude of the biasing force is controllable by the user when assembling the unit. Therefore, it is not necessary that the notches be rectangular, or that they closely conform to the shape of the shelf.
-
FIGS. 8A-8E illustrate alternative upright members that may be used in accordance with the present invention. InFIG. 8A anupright member 111A definesnotches 115A that are generally arcuate, with a relatively flat center portion. For example, the flat center portion of thenotch 115A may have a vertical dimension that closely approximates the width of theshelf 13, to precisely locate theshelf 13. - In
FIG. 8B theupright member 111B comprises notches that each define alip 115B that theshelf 13 may abut against in the assembled display unit. The edges of theupright member 111B above thelips 115B may be angled such that the upper andlower lips 115B are vertically aligned. - In
FIG. 8C theupright member 111C comprises a more than twosemicircular notches 115C. Thesemicircular notches 115C are relatively easy to fabricate, and may be aesthetically more pleasing. The greater number ofnotches 115C may be provided in any of the embodiments, and provides the user with more options for placement of theshelves 13 and/or the option to use more than twoshelves 13. -
FIG. 8D illustrates anupright member 111D similar to 111C, but with muchshallower notches 115D. Because theupright members 111D are biased against theshelves 13 with thesingle taper wedges 23, the notches do not require great depth. The idea here is to provide a surface that engages the shelves that will improve the frictional grip between theupright member 115D and the shelf apertures 17 (relative to an upright member having a smooth edge, e.g.,FIG. 8F ). -
FIG. 8E illustrates anupright member 111E wherein a plurality of protrusions are formed on the outer edge of theupright member 111E.FIG. 6F illustrates anupright member 111F without notches in theupright member 111F. In this embodiment theshelves 13 may be prevented from moving vertically after assembly by frictional forces between theupright member 111F and theshelves 13. - It will be appreciated that any of the upright members shown in
FIGS. 8A-8F may alternatively be formed with angled protrusions similar to that shown inFIG. 6A , for use with thedouble taper wedge 53. - While illustrative embodiments have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.
