Definitions

  • This invention relates to improvements in lightweight collapsible support structures in the nature of easels, book rests, book ends or similar articles that upon unfolding and erection provide upstanding inclined or substantially vertical support or abutment surfaces for display purposes or for supporting or anchoring articles such as pads, books or similar items.
  • This invention relates to improvements in such collapsible structures but particularly of the nature disclosed in my United States patent No.3,990,669 which issued November 9, 1976 and the Canadian counterpart, Canadian patent No.1,010,008 issued May 10, 1977.
  • the principal object of this invention is to provide an improved, self-sustaining, lightweight collapsible support structure including several hingedly interconnected panels adapted upon being extended from a folded state to assume a substantially independent upright stable configuration presenting a principal surface of generally planar configuration from several panels either inclined or supported substantially vertically for display purposes or as a support abutment surface for pads or books or the like.
  • Still another object is to provide a support structure of minimal components readily unfolded and extended into its stable configuration and vice versa.
  • Still another important object is to provide a support structure which can be produced in several configurations for particular uses each having an overall appearance that is pleasing.
  • Still another object is to provide support structures capable of being fabricated from stiff lightweight sheet materials using fundamental manufacturing steps and apparatus which ensure efficiency in production.
  • the principal feature of this invention resides in providing in a collapsible self-sustaining support structure having a substantial measure of rigidity derived from sheet-like panel portions hingedly interconnected along their common abutting edges to define fold axes for limited swinging movement towards and away from one another, a central panel portion flanked by hingedly interconnected side panel portions which are arranged to be supported in substantially fully extended upstanding side-by-side relation in which the central panel portion has a uniform generally quadrilateral perimetral configuration with its uppermost edge having an extent greater than the extent of its lowermost edge, the central and side panel portions flanking same each presenting hingedly interconnected ledge panel portions along their respective lowermost edges in side-by-side relation with the configuration of the lowermost edges being such that the hingedly interconnected ledge panel portions are foldable in unison into a generally horizontal disposition only when the aforementioned central and side panel portions are in substantially fully extended side-by-side relation.
  • the aforementioned structure provides a relationship of panels whose relative positions can be fixed or secured against displacement through the manipulations outlined and when deposited upon a flat supporting surface is sufficiently rigid and stable so as to support or accommodate articles for display or books or in certain embodiments serve as book ends.
  • Still another feature resides in providing multiple or compound fold axes between the principal central panels and associated side or gusset panels whereby upon collapse and folding of the panel portions one upon the other one section can be received within the other whereby compactness may be readily achieved.
  • Still another feature resides in providing structures of the type indicated which can be cut or struck from a single sheet of suitable material with fold lines defining fold axes inscribed'or impressed therein whereby jointing, bonding or interconnecting of only a minimum number of panel portions is required.
  • the panel portions may take the form of stiff rigid perimetral-inserts encased in suitable plastic sheeting or like material with the respective fold axes of such composite article being defined by several thicknesses of such sheeting formed together by sealing or by stitching or otherwise adhered.
  • the fold axes or hinged interconnections are coincident with the panel portion edges.
  • the fold axes are defined by impressing or inscribing lines in such plastic sheeting in the die cutting operation. This leaves a minimal number of joints to be fabricated by heat sealing or by using appropriate adhesives.
  • Figures 1 to 5 inclusive is preferably derived from a one-piece layout or blank having the configuration illustrated in Figure 4.
  • the blank of Figure 4 includes a centrally located first panel portion 10 flanked by side panel portions 12 and 14 of opposite symmetry, along each of panel portions 10, 12 and 14 are presented integral ledge panel portions 16, 18 and 20 along lowermost edges 22, 24 and 26 respectively.
  • Central panel portion 10 has a uniform generally quadrilateral configuration with uppermost edge 28 thereof having a greater extent than lowermost edge 22 such that side edge formations separating the respective associated central and side panel portions and ledge panel portions generally indicated at 30, 32 are angled convergingly downwardly respectively and are constituted by pairs of impressed or inscribed fold lines indicated at 34a, 34b, 36a and 36b in Figure 4.
  • Hingedly connected along uppermost edge 28 constituted by an impressed or inscribed fold line as indicated in Figure 4 is a second central panel portion 42 adapted to support first mentioned central panel portion 10 in upstanding relation as may be better understood from Figure 2 of the drawings.
  • the hinged connection of the two central panel portions 10 and 42 allows for swinging movement of the central panel 10 with respect to the central panel 42 first forwardly from a next adjacent folded position to an inclined position, and then reversely when the structure is to be collapsed.
  • the preferred embodiment reveals a hinged connection along uppermost edge 28, whereas this connection may be omitted to provide a gap or slot therebetween for the reception of a flap or cover by means of which a pad can be anchored against dislodgement.
  • Central panel 42 is flanked by and hingedly connected to generally triangularly shaped side panel portions or gussets 44 and 46 which present along their respective hypotenuses as at 48 and 50 anchoring panel portions 52 and 54 which are adapted to be secured in abutting relation against the respective rear surfaces side panel portions 12 and 14 as best seen in Figure 2 of the drawings.
  • hinged connections extending along side edges of central panel portion 42 and flanking side panel portions 44 and 46 as indicated generally at 56 and 58 in Figure 4 comprise separated pairs of fold lines in the case of hinge connections 56 as at 60a, 60b, 60c and. 60d and in the case of hinge connection 58 as at 62a, 62b, 62c and 62d.
  • hinged connections 56 and 58 so defined have an extent so as to embrace the enclosed central panel portions 10 and 42 and associated side panel and gussets when the support structure is collapsed as revealed by Figure 3 of the drawings.
  • hinged connections 56 and 58 add stability derived from the assumed column or shaping when the article is extended into the fully erect position revealed by Figure 2.
  • ledge panel portions 16, 18 and 20 can be folded in unison about their common respective edges or fold axes 22, 24 and 26 which secures panel portions 10, 12 and 14 respectively in substantially fully extended coplanar relation against collapse thereby inherently preserving the erect configuration, which structure so defined has a loading capability, and resists deformation when deposited upon a suitable supporting surface.
  • the support structure of Figures 1 to 5 inclusive is intended to carry an opened book supported lowermost on a suitable sponge pad 70 or the like mounted upon ledge panel portions 18 and 20 which sponge pad tends to prevent the cover of the book and pages from closing.
  • Ledge portions 18 and 20 are provided with notches 72 and 74 respectively which notches are adapted to cooperate with notches 76 and 78 respectively presented by side panel portions 12 and 14 in that elastics can be looped around the respective side panel 12 and ledge panel 18 and side panel 14 and ledge panel 20 and anchored in the aforementioned respective notches to hold the leaves or pages from flipping over.
  • Fold axes formations indicated generally at 92 and 94 of Figure 8 separate panel portions 80 from side panel portions 82 and 84 respectively with the uppermost edge 96 of central panel portion 80 constituting a fold axis of perimetral extent greater than the perimetral extent of lowermost edge 98a but provided with a slotted arrangement as at 98b.
  • Lowermost edge 98a defining the fold axis between central panel portion 80 and ledge panel portion 86 in the fully extended disposition is aligned with the fold axes 100 and 102 of ledge panel portions 88 and 90 respectively.
  • Central panel portion 80 is hingedly connected along the unslotted portion of uppermost edge 96 to a second central panel portion 104 flanked by gussets 106 and 108 along hinged connections 110 and 112 respectively in the same manner as described in relation to the embodiment of Figures 1 to 5 exclusive.
  • Gussets 106, 108 present securing panel portions 118 and 120 separated by fold lines 114, 116 respectively which are adapted to be secured to panel portions 82 and 84 respectively of central panel portion 80 as best seen in Figure 7.
  • FIGS 10 to 13 inclusive disclose still another preferred embodiment of the invention.
  • Figure 12 illustrates the layout blank used to fabricate the articles depicted in Figures 10, 11 and 13 and as with the embodiment of Figures 6 to 9 inclusive the layout blank includes a first central panel portion 120 flanked by and hingedly connected to side panel portions 122 and 124 each provided lowermost with ledge panel portions 126, 128 and 130 respectively.
  • the uppermost perimetral edge 150 defines a fold axis along which a second central panel portion 132 is hingedly connected to first central panel portion 120.
  • Central panel portion 132 is also flanked by side panel portions or gussets 134 and 136 carrying outermost connecting panel portions 138, 140 respectively, the fold axes defined by hinge formations 142 and 144 corresponding to those earlier described in connection with the first preferred embodiment of Figures 1 to 5 inclusive at 30 and 32 and the fold axes or hinges indicated at 146 and 148 reflecting a structure similar to those indicated at 56 and 58 of the embodiment of Figures 1 to 5 inclusive.
  • the erect support structure depicted in Figures 10 and 11 is achieved by securing connecting panels 138 and 140 to the rear surfaces of side panel portions 122 and 124 respectively, as best seen in Figure 11. So erected, such structure presents front panel portions 120, 122 and 124 in substantially perpendicular relation to the composite forwardly extending ledge formation comprising ledge portions 126, 128 and 130.
  • the substantially fully extended coplanarity achieved in accordance with the embodiments illustrated among the principal panel portions 10, 12 and 14 of Figure 1, 80, 82 and 84 of Figure 6 and 120, 122 and 124 of Figure 10 is a limit position and provides automatic alignment of the integral fold axes presented by the respective ledge panel portions which are adapted only in such limit position to move in unison to project forwardly and thereby secure the extended disposition of the respective principal panel portions and associated supporting panel portions to lock same against collapse and impart stability when the article support is deposited upon a suitable support surface.
