Abstract
The disclosed collapsible bookcase has generally rigid planar rear and side panels, and first couplings provided between them operable to pivot the side panels approximately 270 degrees between a collapsed condition with the side panels closely adjacent and generally parallel to the rear side of the rear panel and a set-up condition with the side panels angled normal to and forwardly away from the front side of the rear panels. Generally rigid planar shelves are pivoted by second couplings between the rear ends of the shelves and the rear panels operable to pivot the shelves approximately 90 degrees between a collapsed condition having the shelves adjacent and generally parallel to the front side of the rear panel and a set-up condition extended between the end panels and at different vertical spacings from one another. Supports between the end panels and shelves hold them in the set-up condition.
Description
- Bookcases commonly have peripheral structural components rigidly connected together end-to-end, with a transversely extended rear structural components connected to the peripheral components at their rear edges. Vertically spaced shelve components are supported by the peripheral and/or rear components, frequently being adjustable to different vertical separations. However, the rigidly connected peripheral and rear structural components define a bookcase having a bulky hollowed out shape, making it difficult for transfer or storage even though it may not be heavy.
- An object of this invention is to provide a collapsible bookcase fabricated from separate generally planar peripheral, rear and shelf components, with couplings on the components pivoting them together for being shifted between a rigid set-up bookcase condition and a collapsed condition where the components are compactly arranged for easy transfer or storage.
- Another object of this invention is to provide a bookcase according to the previous object where each planar component and its couplings are integrally made of injection molded plastic, allowing for quick and easy component assembly and pivotal movement between the set-up and collapsed conditions.
- One feature of the invention provides that the bookcase side peripheral components are pivotally connected at their rear edges to the side edges of the rear peripheral component, and are in the set-up condition projected forwardly and generally normal to the rear component and are pivoted approximately 270 degrees therefrom to the collapsed condition disposed generally parallel to and adjacent the rear face of the rear component.
- Another feature of the invention provides that the bookcase shelve components are pivotally connected to the rear component at vertically spaced locations, and in the set-up bookcase condition are projected forwardly and generally normal to the rear component and are pivoted approximately 90 degrees therefrom to the collapsed bookcase condition disposed generally parallel to and adjacent the front face of the rear component.
- Another feature of the invention provides a bookcase design that allow several like bookcases to be stacked vertically on top of one another so as to become laterally interlocked for forming a composite bookcase having the cumulative shelf total and vertical shelf separations of the separate bookcases.
- These and other objects and features of this invention can be more fully understood and appreciated after reviewing the following specification, including as a part thereof the accompanying drawings, wherein:
-
FIG. 1 is a front elevational view of the improved bookcase, shown in the opened or set-up position; -
FIG. 2 is a top plan view of the bookcase, showing also in phantom the side peripheral panels in the collapsed position against the rear side of the back peripheral panel; -
FIG. 3A is a sectional view as seen generally from lines 3-3 inFIG. 1 , showing also in phantom the shelf components in the collapsed position against the front side of the back panel; -
FIG. 3B is side elevational view of the bookcase in the collapsed position, with the shelf components against the front side of the back panel and the side panels against the rear side of the back panel; -

FIG. 8 is an elevational view as seen generally from lines 8-8 inFIG. 7 . - The
bookcase 10, as illustrated in the set-up condition inFIGS. 1, 2 and 3A, has separate components comprised of a verticalrear panel 12,vertical side panels rear panel 12, and upper andlower shelves rear panel 12 and laterally between the spacedside panels bottoms 19 of the side and rear panels lie along a common plane normal to these panels, whereupon thebookcase 10 can upstand vertically from any flat horizontal surface, such as a floor, desk top or the like. Thetop sides 18 of theshelves - The disclosed
bookcase 10 hascouplings shelf components 12 and 14-17 relative to one another, while allowing them to be shifted between the set-up condition ofFIGS. 1, 2 and 3A and a collapsed condition ofFIG. 3B , and has supports 40 that interlock and hold the components in the set-up condition.FIGS. 2 and 3 A also show in phantom the side panels and shelves, respectively, in the collapsed conditions. - Each
coupling - More specifically, three axially separated
couplings 20 pivot each shelf to therear panel 12, allowing approximately 90 degrees shelf rotation (see arcs 21 inFIG. 3A ) between the set-up and collapsed conditions, with shelfrear edge 26 forwardly spaced from rearpanel front side 22. Thecouplings 20 of the twoshelves lower shelf 17, so that the collapsed shelves lie parallel to therear panel 12 and coplanar with one another, with each shelftop side 18 generally flat against the rearpanel front side 22. Thecouplings 20 for theupper shelf 17 further might be located to have the collapsed upper shelffront edge 23 line up even with or below the rearpanel top edge 24. - Also, three axially separated
couplings 30 pivot theside panels rear panel 12, allowing side panel rotation of approximately 270 degrees (seearcs 31 inFIGS. 2, 7 ) to shift between the set-up and collapsed conditions. In the collapsed condition (FIG. 2 in phantom, andFIG. 7 ), theside panels rear panel 12 and coplanar with each other, with the sidepanel front edges 32 being laterally spaced apart and each side panelouter side 33 substantially against the rearpanel back side 34. Thetop edges side panels bottom edges 19 of these panels. - The supports 40 (
FIGS. 4, 5 , 6) project inwardly from each side panel to vertically underlie and support each shelf in the set-up condition, whereas theshelf side edges 37 otherwise might be spaced inwardly from the side panelinner sides 38. - The collapsed
shelves side panels rear sides rear panel 12, to have the collapsed bookcase 10 (seeFIG. 3B ) compact compared to the set-up bookcase (seeFIG. 3A ), with an overall thickness only slightly more than the cumulative thickness of thestacked components 12, 14-17. This makes the compact collapsedbookcase 10 particularly suited for convenient transfer or storage. -
FIGS. 1, 2 , 3A and 3B show thecomponents 12 and 14-17 without details, appearing generally as solid and planar. As a preferred embodiment will have each panel or shelf component injection molded of durable plastic, with the couplings and support being integral therewith, more detailed panel, coupling and support constructions are illustrated inFIGS. 4-8 . - Thus, each panel and shelf component might have a main generally planar portion interrupted by spaced interior openings, with flanges angled off of the main planar portion at its perimeter edge and at the edges of its interior openings, to add load carrying capacity and resistance against bending.
- Specifically, the
rear panel 12 might have mainplanar portion 45 interrupted byinterior openings 46, withperimeter flange 47 and openingflanges 48 formed off of the main planar portion. Eachside panel planar portion 50 interrupted byinterior openings 51, withperimeter flange 52 and openingflanges 53 formed off of themain portion 50. Eachshelf planar portion 55 interrupted byinterior openings 56, withperimeter flange 57 and openingflanges 58 formed off of themain portion 55. The shelves can be identical, while the side panels are mirror or right and left hand images of one another. - Each
coupling 20 might have itssocket 62 formed on the shelf, closely adjacent therear side 26, and itsshaft 63 formed on the rear panel forwardly of therear front side 22. Thesocket 62 opens downwardly from the shelf underside suited to overlieshaft 63, for carrying load on the set-up shelf. Eachshelf socket 62 can be supported bywebs 64 extended rearwardly from therear perimeter flange 57, while eachrear panel shaft 63 can be supported bywebs 65 extended forwardly from the rear panel mainplanar portion 45. Theexterior shelf flange 57 is irregularly tracked forwardly of the shelf to center thesocket 62 within the regular shelf bounds. Proper center spacings of the socket below the shelfupper side 18 and the shaft forwardly from the rear panel front side allow theupper side 18 of the collapsed shelf to lie substantially flat against the rearpanel front side 22. - Each
coupling 30 might have itssocket 72 formed on the side panel, opening toward the side panel outward side, and itsshaft 73 formed on the rear panel. Thesocket 72 thus overlies theshaft 73 for withstanding sideways separating forces away from the rear panel. Eachside panel socket 72 can be supported by webs 74 extended rearwardly from therear perimeter flange 52, while eachrear panel shaft 73 can be supported by theexterior flange 47 centered along the rear panelrear side 34, theflange 47 being irregularly tracked inwardly to form space for receiving the side panel socket. With the socket and pin centers on the planes defined along the side panelouter side 33 and the rear panelrear side 22, the side panel outwardside 33 can lie generally flat against the rear panelrear side 22 when the bookcase is collapsed or closed. - Each
support 40 can include a tubular flange 76 inwardly formed from the end panelplanar portion 50, with an underlying reinforcingweb 77 therebetween. Thesupport 40 might comprise ledge 78 inwardly projecting beyond the side panelinner side 38, suited to underlie and supportshelf perimeter flange 57 in the set-up condition. Anupstanding ledge lip 79 spaced from side panel inner side 38 a distance slightly exceeding the thickness of the shelf perimeter flange can engage and laterally contain each set-up side panel relative to thesupport 40. - The disclosed bookcase has only two shelves, but contours on the bottom and top edges of the side and rear panels allow the stable stacking of like bookcases for forming a four or even six shelf bookcases.
FIGS. 4 and 6 show two stackedbookcases 10, 10A, interlocked by centeredlongitudinal rib 81 upstanding from the top of each side and rear panel and laterally spacededge ribs 83 projected downwardly from the panel bottom edges. - While specific structures have been disclosed, modifications could be made to the bookcase without departing from the inventive spirit. Consequently, the invention is to be defined by the scope of the following claims.
