Definitions

  • the present invention relates to an improvement in a tray for supporting notepaper, and in one aspect to a new configuration of a tray for supporting the stack of notepaper to permit dispensing single sheets from a stack of notepaper without separating the stack from the support.
  • the stack of sheet material comprises a plurality of sheets each of which are coated with a narrow band of readily releasable pressure-sensitive adhesive along one edge and the sheets are stacked with the adhesive coated edge of each sheet positioned above each other adhesive coated edge.
  • the band of adhesive ranges between one-quarter and three-quarters of an inch wide.
  • the individual sheets may be readily withdrawn from the stack by peeling the sheet and its adhesive from the next adjacent sheet in the stack.
  • the adhesive is a readily repositionable pressure-sensitive adhesive such that the separated sheet may be attached to another sheet or other receptor surface and readily removed without tearing the fibers of the other sheet or receptor surface upon later separating the sheet.
  • a stack of this notepaper is adapted to be supported on a holder such as is disclosed in U.S.A. Letters Patent No. Des. 273,798 issued May 8, 1984.
  • This particular prior holder had a surface for supporting the stack of sheet material and relied on the adhesive on the surface of the lower sheet of the stack or on an additional strip of adhesive to secure the stack of sheets or pad to the support surface on the holder.
  • the surface would become soiled or the strip of adhesive applied to the holder became contaminated such that the pad was not secure enough to the holder to permit separation of one sheet from the stack without the separating force being sufficient to also separate the entire stack from the holder, particularly as the number of sheets in the stack was depleted. Therefore, improvements in holders for dispensing the pressure-sensitive adhesive coated notepapers from a stack became desirable.
  • the present invention describes an improved notepaper dispenser which affords a support surface for supporting a stack or pad of sheet material and on a surface which permits writing on the notepaper before the same is removed from the stack.
  • the holder of the present invention provides means for holding the bottom sheet in a stack against movement in the plane of the support surface.
  • the holder for the notepaper is provided with abutment means which projects above the plane of the support surface supporting the notepaper to restrict movement of the stack during the separation of the uppermost sheet from the stack and peeling forces from being applied to the band of adhesive on the lowermost sheets.
  • the present invention relates to an improvement in notepaper dispensers and particularly to an improvement in holders for pads of notepaper which comprise sheets held together with a narrow band of pressure sensitive adhesive material.
  • the holder permits the sheets to be dispensed individually and holds a stack of sheets such that the forces imparted to the stack during the separation of the individual sheets will not separate the stack from the holder.
  • Tho holder comprises a frame having o support surface or platen for supporting a stack of sheet material generally in a plane such that the sheets are supported on a generally planar surface and the sheets may be written upon while in the stack.
  • the holder comprises means for holding the lowermost sheet in the stack to restrict movement in the plane of the supporting surface and abutment means are provided to engage an edge of the stack to restrict movement of the stack during the separation of a sheet from the stack.
  • abutment is positioned opposite the edges of the sheets which are secured together.
  • the means which restricts the bottom sheet in the stack against movement in the plane of the support surface may comprise a plate which fits over the lowermost sheet and clamps the sheet to the holder.
  • Such clamping may be afforded by a pivoted platen which frictionally grips the lowermost sheet and may include pins which perforate the lowermost sheet.
  • the clamping action may be afforded by physical forces applied to the lowermost sheet, such as frictional forces applied by weight, by springs, by the use of magnets, or by physically bending the lowermost sheet such that increased forces are needed to release the lowermost sheet from the support surface.
  • the abutment means may be formed on the frame of the holder or may be formed in the clamping plate.
  • the abutment means projects above the plane of the support platen and engages at least a number of the sheets along the front edge of the stack on an edge opposite the edge where the sheets are adhered together.
  • the abutment means restricts movement of the stack with respect to the support platen including lifting or rotational movement.
  • FIG. 1 there is illustrated a dispenser for a stack of notepaper, which dispenser is generally designated by the reference numeral 11 and comprises a main frame 12 which may be molded and formed of joined parts to have an inner cavity 13 which may be filled with a sand or other heavy material to weight the dispenser.
  • the frame 12 has a bottom plate 14, a rear wall 15, opposed side walls 16 and 17, between which extend a generally planar support 20 for a stack of sheet material.
  • the support 20 extends from the front edge 21 of the holder to a generally vertical member 22, which would be at one end of the stack 30 of sheet material and which, at its upper end, connects with the top 23 of the frame 12.
  • the top 23 is shaped to form a cradle for a writing instrument and continues to a well 24 shaped to receive a refill stack of notepaper, paper clips, or the upper surface surrounding the well 24 may support a nameplate, etc.
  • a platen or planar clamping plate 25 which is adapted for clamping the lowermost sheet 26 of a stack of sheets 30 onto the frame 12 of the holder.
  • the plate 25 is adapted to pivot relative to the frame 12 and cooperates with the support 20 to firmly hold the lowermost sheet 26 in a position between the support 20 and the under side of the plate 25 to restrict movement of the sheet 26 with respect to the plane of the support 20.
  • Extending upwardly from the forward end of the plate 25 is an abutment 31 which engages the edge of the lowermost sheets in the stack.
  • the abutment 31 serves to restrict movement of a stack of sheets with respect to the platen 25 and support 20 during separation of the uppermost sheet in the stack.
  • the abutment 31 serves to restrict movement of a stack of sheets with respect to the platen 25 and support 20 during separation of the uppermost sheet in the stack.
  • Figure 3 illustrates in sectional view a stack 30 of sheet material on the dispenser 11 with the lowermost sheet 26 clamped between the platen 25 and the support surface 20.
  • the clamp holds the lower sheet at a position adjacent the edge where the sheets are joined together as illustrated. This restricts a lifting and peeling force to be exerted between the lower sheet and the pad.
  • the pad or stack of sheet material illustrated comprises sheets of notepaper, approximately twenty pound bond paper, with each sheet coated along one edge with a readily repositionable pressure-sensitive adhesive.
  • the adhesive is coated in a band about one-quarter to three quarters of an inch wide.
  • FIGS 4, 5 and 6 illustrate the details of the clamping plate and the support.
  • the main frame 12 is provided at its forward end with a cut-away as illustrated at 34 to leave a narrow resilient finger 35 extending along the lateral edge of the frame 12.
  • a fulcrum member 37 Extending outward from the finger 35 is a fulcrum member 37 which defines the fulcrum for the pivoting clamping plate 25.
  • a stop member 39 which is spaced from the front edge of the frame 12.
  • the platen 25 is formed with depending side members 40 which cover the lateral edges of the frame 12 and the cover members 40 are provided with interior recesses cooperating with the fulcrum members 37 and the stop members 39 affording limited pivotal movement of the plate 25 and positioning of the plate 25.
  • the under surface of the clamping plate 25 may be provided with transversely spaced pointed projections 45 which extend from the under surface of the plate 25 and cooperate with recesses 46 in the support member 20 such that upon insertion of the lowermost sheet 26 in the stack 30 the projections 45 will penetrate the sheet and hold the sheet securely against movement with respect to the support 20.
  • the clamping plate 25 could also be formod with a resilient detent similar to the stop member 39 which would lock in a cooperating recess to frictionally hold the bottom sheet 26 securely between the support 20 and plate 25.
  • the dispenser 11 with the pivoted clamping plate 25 locks the lowermost sheet in position and holds the paper in a predetermined plane with respect to the support 20 and the plate 25 such that the user may write on the sheets of notepaper before separation from the stack down to the very last sheet without encountering an uneven writing surface beneath the next to the last sheet in the stack.
  • FIG. 7 illustrates a dispenser generally designated 51 comprising means defining a frame having means defining a support surface 52. Embedded in the support surface 52 and extending transversely thereof are a pair of permanent magnets 53 and 54 which are bars of a permanent magnetic material.
  • a clamping plate 55 formed of a magnetic material may be inserted between the lowermost sheet 26 of a stack of sheet material and the next adjacent sheet and the magnets 53 and 54 will clamp the sheet against the support 52 with sufficient force to hold the sheet 26 and the stack 30 against movement with respect to the support surface.
  • the magnetic plate 55 is provided with a raised and transversely extending abutment 57 which engages one or more of the sheets in the stack adjacent the front edge of the stack to hold the stack against movement.
  • the end 59 of the plate 55 may be bend downwardly across the width of the plate to position the plate with respect to the front edge 60 of the holder, and position the opposite edge of the plate adjacent the adhesive band of the stack.
  • the dispenser 61 may have a frame formed of wood, stone, or other solid material and shaped to define a support surface 62.
  • the support surface 62 may be formed on a surface recessed between edges 63 and 64 to afford an improved artistic design for supporting the notepaper.
  • the stack 30 of notepaper is positioned within the recessed area and the lowermost sheet in the stack is clamped between a clamping plate member 65 and the support surface 62 as illustrated in Figure 8.
  • the clamping plate 65 as shown more clearly in phantom view in Figure 8 and partially in section appears generally U -shaped comprises an upper support plate 66 that fits over the lowermost sheet in the stack and forms a support or writing surface for the sheet material.
  • the clamping plate 66 has a depending flange portion 68 which has a thickness equal to or slightly greater than the height of the front edge 69 of the holder 61 and has a lower locking plate 70 which fits beneath the holder 61 and the support surface 62 thereof.
  • the clamping plate 67 In operation, as the clamping plate 67 is inserted over the lowermost sheet and moved rearwardly with respect to the recess in the holder 61, the normal resilience of the material forming the clamping plate 67 pinches or binds and frictionally holds the lowermost sheet of the stack firmly on the support 62. The abutment 67 in the meantime engages the front edge of the stack to restrict any rotational movement of the stack with respect to the support plate 65.
  • FIG. 9 A similar embodiment for a notepad holder and dispenser is illustrated in Figure 9.
  • This holder generally designated 71, formed of a solid material and generally wedge shaped, has an upper support surface 72 for supporting the stack 30 of notepaper.
  • a clamping plate for clamping the lowermost sheet in the stack to the holder 71 and in position on the support surface 72 comprises a clamping member 73 comprising a clamping plate 74 adapted to extend over the lowermost sheet in the stack and to support the stack and clamp the lowermost sheet against the support surface 72.
  • Extending upward from and cut from the plate 74 defining the support platen is a bent flange portion 75 defining an abutment member engaging the stack 30 along the lower front edge of the sheet material.
  • the plate 74 is joined to generally U-shaped clamping members including sidewalls 76 which are trapazodial in shape to conform substantially to the shape of the ends 77 of the frame forming the holder 71.
  • side members 76 are connected reversely turned flanges 78 serving to hold the plate 74 to the holder 71 when the support plate is slid up over the frame between lowermost sheet in the stack and the next sheet to a position near the coating of adhesive on the lowermost sheet to clamp the lower sheet in place.
  • Figure 10 shows a further embodiment which comprises a holder for notepaper which is a unitary member without detachable pieces or pivotally joined pieces.
  • the dispenser 81 comprises a frame 82 which may be molded of a suitable material and provided with a support surface 84 for supporting the stack 30 of notepaper.
  • the lowermost sheet 26 is held tightly to the support surface 84 by the sheet being directly sharply back upon itself and then reversely directed again to bind the sheet in a narrow slot 85 defined by generally parallel wall members formed in the support plate 84 at an acute angle to support plate 84 which thus clamps the sheet 26 against vertical movement with respect to the support 84.
  • An abutment 86 is formed at the front edge of the holder and of the support surface 84 to engage the lowermost sheets in the stack to restrict movement of the stack as the result of the lifting and peeling forces applied to remove a sheet from the stack of sheets 30.
  • the lowermost sheet is peeled from the forward edge of the pad and then directed through the slot 85 and drawn forward again to pull the pad down onto the upper edge of the support surface 84.
  • the frictional forces applied against the opposite edges of the bent or folded sheet restricts its movement on the support surface 84.
  • the clamping action applied to the lowermost sheet extends to a position adjacent the adhesive bonded edge of the stack.
  • the edge of the clamping member is thus one quarter of an inch to one inch from the edge of the stack opposite the abutment, when on the support surface.
