Definitions

  • This invention relates to lightweight collapsible support structures and more particularly to those structures that include book covers or ring binders as integral parts thereof for displaying the contents thereof or serving as an easel or other similar purpose.
  • This invention relates to improvements in such collapsible structures but particularly of the nature disclosed in my US-A-3,990,669 which issued November 9, 1976 and the Canadian counterpart, CA-A-1,010,008 issued May 10, 1977.
  • My US-A-3,990,669 discloses a lightweight collapsible support structure such as a book support and cover which comprises four panels which are so hingedly connected together that the structure may upon being unfolded extend into a self-sustaining predetermined configuration in which the structure can sit upon a flat surface and present three forwardly facing inclined panels.
  • the structure may be compactly folded up when collapsed for storage or for carrying.
  • US-E-21,371 discloses a portable displayer of the easel binder type which, when unfolded, can be placed on a flat surface to provide a front inclined display board, which is supported by a rear oppositely inclined support board connected to the front board along the top edge.
  • the two boards together provide an inverted "V" formation when unfolded and are prevented from assuming too great an angle with one another by means of flexible tapes interconnecting the two boards.
  • the principal object of this invention is to provide an improved selfsustaining lightweight collapsible support structure for a book cover or binder which is integrally associated therewith so that it is adapted, if desired, upon the book cover or binder being extended from a closed or folded position to a substantially fully extended open position to be supported upon a suitable surface in inclined erect stable configuration in order that its contents can be readily displayed or the cover used as an inclined working surface or easel.
  • Another important object is to provide a collapsible support structure of relative simplicity easily manipulated from its compact state into the independently erect stable configuration.
  • Still another object is to provide a collapsible support structure which in the fully extended position can be releasably locked in place to preserve its stability.
  • Still another important object is to provide a cover or binder with support structure disposed therebelow thereby providing for ready viewing of the contents thereof or presenting a clear work surface and avoiding interference with enclosed pages or work sheets or the like when folded up.
  • Still another very important object is to provide a support structure capable of being fabricated from low cost lightweight material using basic manufacturing steps and available apparatus requiring low labour content so as to ensure efficiency of production and reduce costs of manufacture.
  • a collapsible support structure comprising a cover formation including a stiff central panel portion of generally uniform quadrilateral perimetral configuration arranged so as to present upper, lower and side edges and a pair of stiff side panel portions flanking said central panel portion and hingedly connected thereto along opposite side edges for swinging movement from a fully closed position with side panel portions in opposed relation to a substantially fully extended open position in side-by-side co- planar relation with said stiff central panel portion and reversely; and means for supporting said cover formation in inclined relation from below with said aforementioned side panel portions disposed in said substantially fully extended open position, said supporting means including a stiff central strut means having upper, lower and side edges hingedly interconnected adjacent its upper edge to said central panel portion to swing from a position there-against to a position in which its lower edge is remote from said central panel portion, and shiftable stiff side struts means extending between each said side panel portion of said cover and said central strut means, characterized in that each said side strut
  • One embodiment of the invention resides in providing a cover, suitable as a book cover or as a binder.
  • the collapsible structure through manipulation closely embraces the book cover when closed and can assume an extended erect stable configuration locked against collapse when the cover is fully opened.
  • a book or binder may include an integral collapsible supporting structure but one of substantial strength so as to better resist deformation or collapse in the fully erect disposition.
  • each flanking side panel of the cover formation include an elongated slot formation of selected configuration so as to present a channel formation with corresponding locking pockets at the remote ends thereof follower members presented by respective shiftable side strut formations throughout the range of relative movement of the components with the locking pockets and cooperating follower members being adapted to secure the components against dislodgment not only in the fully extended position but in the fully folded position so as to ensure uniform displacement and avoid distortion in use.
  • Still another embodiment resides in providing support structures which can be derived from substantially rigid sheetlike panels having a reproducible perimetral configuration so that they can be struck from flattened sheets of material in a conventional die cutting or stamping operation and in which fold axes can be simultaneously impressed or scored to define the several hinge connections.
  • FIG. 2 to 5 inclusive of the drawings takes the form of a ring binder formation 12 provided with a collapsible support structure indicated generally at 14, the components of same being integral and derived from a blank or layout 16 illustrated in Figure 1.
  • the blank or layout 16 is struck from a suitable sheet of stiff plastic, for example, polyethylene of a selected thickness so as to ensure stability of the structure.
  • the layout 16 includes a first central panel portion 18 separated from flanking side panel portions 20, 22 by fold axes indicated by broken lines 24, 26 which are provided either by compressing the plastic sheet linearly during the die cutting operation or by inscribing the layout with suitable knife edges in another step.
  • Elongated slots 28, 30 extend through side panel portions 20, 22 in a somewhat diagonal direction said slots 28, 30 having in the preferred embodiment opposite symmetry and each terminating at their remote ends in anchoring pockets 28a, 28b and 30a, 30b respectively for a purpose to be explained.
  • Two side strut formations 36, 38 flank central strut 34 and are separated therefrom by impressed or inscribed fold axes 40, 42 which are parallel and in the preferred embodiment illustrated in the drawings slightly more widely separated than parallel fold axes 24, 26 separating side panel portions 20, 22 from central panel portion 18.
  • Strut formations 36, 38 include gusset panel portions 44, 46 respectively which prevent reinforcing panel portions 48, 50 being separated from gusset panel portions 44, 46 by impressed or inscribed fold axes 52, 54.
  • fold axes 52, 54 extend diagonally from the intersection of respective fold axes 40, 42 and fold axis 32 whereby as best seen in Figure 3 reinforcing panel portions 48, 50 can abut the rear surfaces of side panel portions 20, 22 in the disposition illustrated.
  • Reinforcing panel portions 48, 50 are each provided with openings therethrough as at 56, 58 respectively in which follower pins 60, 62 are adapted to be anchored, as illustrated in Figures 2 to 5 inclusive.
  • Follower pins 60, 62 include head portions 60a, 62a, respectively and suitably dimensioned shank portions 60b and 62b respectively which shank portions are adapted to be disposed within elongated slots 28, 30 for sliding movement therealong and secured against withdrawal therefrom by means of locking washers 64, 66 respectively fitted over and suitably secured to the ends of shank portions 60b, 62b remote from the head portions 60a, 62a in a manner so as to closely draw washers 64, 66 against the forward surfaces of side panel portions 20, 22.
  • follower pins 60, 62 register within anchoring pockets 28a, 30a respectively of slots 28, 30 when the supporting structure 14 is collapsed against the rear surfaces of central and flanking panel portions 18, 20, 22 of ring binder 12 as shown in Figure 2.
  • follower pins 60, 62 can register within locking pockets 28b, 30b respectively of slots 28, 30 when the supporting structure 14 is in the fully erect extended position and depends rearwardly below the inclined central and flanking panel portions 18, 20, 22 of ring binder 12 as revealed particularly by Figure 3 and Figure 5 of the drawings.
  • flanking side panel portions 20, 22 and flanking side strut formations 36, 38 are held against separation by the follower pins 60, 62 registered within upper locating pockets 28a, 30a, of elongated slots 28, 30.
  • the fold axes 24, 26 of ring binder formation 12 and the fold axes 40, 42 of collapsible support structure 14 are substantially coterminous in the disposition shown in Figure 2 so that the composite article moves as a unit towards the fully closed or folded position.
  • the composite folded article can be treated simply as a binder and handled in the usual manner.
  • Supporting structure 14 illustrated in Figure 3 is shown fully extended having been displaced rearwardly by opening wide ring binder 12 to bring flanking side panel portions 20, 22 into side-by-side co-planar relation with central panel portion 18.
  • Such movement swings central strut 34 rearwardly downwardly about fold axis 32 to present its lowermost edge 67 to a supporting surface 68 of a desk 80 revealed by Figure 5 and draws associated flanking side strut formations 36, 38 with it likewise presenting their lowermost edges 69, 70 respectively to surface 68.
  • the composite article illustrated exposes the contents of the ring binder 12 for examination or for viewing in the style of an easel or presents a work or display surface for any suitable purpose.
  • the conventional three-ring structure 76 of binder 12 in the several Figures 2 to 5 inclusive is optional but desirable where the structure is used as a notebook, since the pages when turned tend to lie flat against the inclined surfaces presented by the coplanar panel portions 18, 20, 22.
  • Removal of the three-ring structure 76 provides an extended flat surface for the mounting of drawings or for the displaying of products and the like.
  • This arrangement dictates controlled movement of the components so that whether the support structure 14 is seized and moved either into the collapsed or extended position the associated binder formation 12 is correspondingly displaced. Likewise, if the binder formation 12 is displaced the support structure 14 is correspondingly altered.
  • slots 28, 30 are selected in the preferred embodiment so that they are as widely separated as possible which tends to afford maximum resistance of the erected article to deformation or collapse. Moreover, the strength of the composite article can be enhanced through the selection of more rigid or thicker sheet material for the integral panel portions.
  • the inclination of the binder panel portions 18, 20, 22 in the fully extended disposition of Figures 3, 4 and 5 can be altered by adjusting the relative dimensions of the respective front panel portions 18, 20, 22 of binder formation 12 and central strut 34 of the support structure 14 as by extending central strut 34 and associated flanking side strut formations 36, 38 for example, to achieve a more upright disposition and vice versa.
