  • the easel 10 has a pedestal base portion 11 and a display portion 12, upon which a pad of paper P may be affixed or indicia placed thereon for display to a group of people in a conference or meeting situation.
  • the pedestal base portion 11 has spaced apart feet 13 and upright members 14, which may be bridged by the upper portion thereof defining compartments 15 for holding markers, tape and the like.
  • Legs 18 are arranged and foldable into corresponding grooves 19 on the rear wall 17 of the pedestal base portion 11.
  • a flat display board 20 is on one face of the display portion 12, and is intended to back up a writing pad P or other display.
  • a spring clamp assembly 21 is secured to an upper edge of the display board 20 so that a pad P may be clipped by the spring clamp assembly to the display board 20 for securing the pad P thereon in a way for pages of the pad to be flipped over the top 22 of the board.
  • Lifting handles 23 may be molded into side edges 24 of the display portion 12 for easy and balanced lifting and collapsing of the display portion relative to the pedestal base portion 11.
  • the legs 18 are preferably tubular and U-shaped and have a bottom member 25 bridging upright side members 26 which are pivotally secured to the rear wall 17 of the pedestal base portion 11 by means of upper toggle bracket assemblies 27 through short toggle links 27a, preferably screw mounted to the rear wall and leg.
  • the side leg members 26 also are secured to the rear wall 17 by lower toggle bracket assemblies 28, preferably also screw mounted to the rear wall and leg, through long toggle links 29, which define arcs for moving the legs 18 toward and away from the pedestal base portion 11 during set up and storage of the easel 10, as shown schematically in Figure 15, which depict the movement of the legs from position 1 to position 2, and vice versa, in the direction of the respective arrows, as the leg ends 51 are articulated into and out of the apertures 52, in a manner and for a purpose hereafter discussed.
  • the leg side members 26 have an integral cross member 30 at the connection of the toggle links 29 to provide rigidity of the structure when set up.
  • the rear wall 17 of the pedestal base has several recess and protrusions.
  • Recesses 31 provide handles for carry the easel 10 selectively from either side of the easel when collapsed.
  • Recess 32 provides a handle for carry the easel by the leg cross member 30 in an upright position when collapsed.
  • Recess 33 provides rigidity to the pedestal base portion 11 and includes kiss-offs or stress absorbing wells 33a for absorbing strain during collapse and extension of the display portion relative to the base portion.
  • Bottom Recess 34 may be used for grasping the legs 18 and pulling them out of the leg recesses during set up.
  • Leg cross member protrusions 35 act as guides for properly seating the leg cross member 30 when the legs are closed against the pedestal base portion in the leg recesses 19.
  • a rounded protrusion 36 having an inverted V shaped cross section is arranged across the lower side of the rear wall and reinforces the wall 17.
  • the rear wall 37 is unitary with the front wall forming the display board 20, the rear wall has a plurality of ribs 38 and stress absorbing wells 39, which stiffen and space apart the front display board 20 and rear wall 37 and absorb stress during extension and collapse of the base and display portions 11 and 12, respectively.
  • ribs 38 On each side of and between the ribs 38, are a plurality of ramps 40 which when the easel is assembled preferably have a steeper taper in the direction of the feet 13 and a relatively more shallow taper in the direction of the top of the display board, and below each of these ramps 40 is a stress absorbing well 41.
  • a ledge 43 may be provided on the bottom edge of the display board 20 which can act as a lip for balancing a marker when the easel 10 is in use, and this ledge 43 also interlocks with rounded protrusion 36 on the rear wall 17 of the pedestal base portion 11 when collapsed; and the upper face of the board top 22 has a recess 42 which corresponds to a protrusion 43a on the rear wall 17 of the pedestal base portion 11.
  • the spring clamp assembly 21 is preferably screw mounted to the front wall of the display board 20 and may have posts 44 having free ends over which drilled holes H in the pad are installed, and this assembly preferably comprises an inverted L shaped clamp plate 45 arranged over the face of the board 20 for holding the upper edge of the pad P and a backer strip 46 which has a spring 47 urging the plate 45 over the pad toward the strip 46.
  • the rear wall 37 of the display portion 12 is formed with spaced apart vertically arranged tracks 48 and ridges 49, and the pedestal base portion 11 has inside edge member 50 formed corresponding to and interlocking with the tracks 48 and ridges 49 for sliding the display portion 12 upwardly or downwardly along the inside edge members 50 relative to the display portion 12 for elevating or lower the display portion.
  • the rear wall 37 of the display portion 11 has formed in it two sets of wedge shaped notches, one set arranged near the top 55 and the other set arranged near the bottom 56 of the display portion rear wall 37, each vertically and horizontally aligned, for receiving the leg ends 51, thus locking the display portion relative to the base portion selectively in the table top position shown in Figure 12 (using the top set 55 of notches) or the floor position shown in Figure 13 (using the bottom set 56 of notches).
  • bars 57 may be formed on the front wall 16 of the base portion, above the apertures 52, and corresponding bumps 58 may be formed in the rear wall 37 of the display portion to restrict the movement of the display portion 12 downwardly on the base portion 11 and to help hold the portions in position once adjusted, as shown in Figures 12 and 13.
  • the display portion 12 when the display portion 12 is telescoped downwardly over the base pedestal portion 11 in the manner described, the compartments 15 are closed and covered by the display portion. Thus, materials stored in these compartments may be safely stored, transported and reused when the easel are needed again.
  • easels 10 are stored in the position shown in Figure 2, except the legs 18 are folded against the leg recess 19, laid horizontally stacked one easel upon the next easel, so that they interlock, as described, for stability.
  • the upper easel is removed from the pile, and its display portion 12 may be extended, as shown in Figure 1, if used on a floor, or telescoped, if used on a table, as shown in Figure 2, with the legs folded away from the pedestal base 11 and in interlocked position with the display portion 12, as shown in Figures 12 and 13, respectively.
  • a change from floor mount to table mount, or vice versa may be easily accomplished, by slightly folding the leg ends 51 to clear the notches 55 or 56, moving the board 20 upwardly or downwardly, and re-locking the leg ends into the corresponding notches.
