Definitions

  • This invention relates to a suspension device and, more particularly, relates to a suspension device system and to a method for suspending articles, signs and ceiling-tile rails.
  • U.S. Patent No. 6,394,873 issued May 28, 2002 describes a ceiling suspension device including a magnet anchor having a steel split ring for suspension of a rod by a string or wire.
  • U.S. Patent No. 6,422,622 issued July 23, 2002 describes an installation and removal device for installing and removing magnet anchors from magnetic ceiling structures such as ceiling-tile rails for the support of a ceiling sign by rings carried by the magnet anchors.
  • Double hook wire devices are commonly used to hang signs straight and level. However, such devices are limited in length and have to be used in multiple, or adjusted to length by screw clamps. Beaded, jack or plastic chains in combination with links or "S" hooks can be used to adjustably hang signs. However, S hooks can be easily dislodged.
  • the suspension device of the invention comprises a loop line including a pair of side by side cords of equal length and knots equispaced along said cords for joining the cords together and defining loops between the knots.
  • the cords are limp monofilament with knots tied or are string or thin rope made of several strands braided, twisted or woven together and the knots for joining the cords together are formed by interlacing, braiding or looping the cords.
  • the strands are selected from at least one of polymer, polyester or metal wire fibres.
  • the loop line has a proximal end terminating at a knot and a distal end terminating in a knot, the proximal end of the loop line is wrapped around or inserted in a hole in the item, the distal end is passed through a loop formed in the loop line at the knot at the proximal end to form a hitch attached to the item, and the loop line is hung from a knot formed in the loop line at the distal end.
  • the system the invention for supporting a sign or ceiling-tile rail from ceiling supports comprises a plurality of loop lines, each loop line comprising a pair of side by side cords joined together by knots at equal intervals along their length to form a plurality of equispaced loops along the length, said loop line having a lower proximal end and an upper distal end, whereby the lower proximal end of the loop line can be inserted through an opening in a sign or ceiling-tile rail to be suspended, and the upper distal end passed through a loop formed at the lower proximal end of the length to form a hitch attached to the sign or ceiling-tile rail, and the upper distal end of the loop line of an equivalent number of loops can be attached to the ceiling support.
  • each loop line comprising a pair of side by side cords join together by knots at equal intervals along their length to form a plurality of equispaced knots defining equispaced loops along their length, said loop lines having a lower proximal end and an upper distal end, comprising inserting the lower proximal end of the loop line through a sign opening, passing the distal end of the loop line through a loop at the lower proximal end to form a hitch attached to the sign, and attaching a loop at the upper distal end of the loop line at an equal number of knots counted from the lower distal ends to ceiling attachment means, whereby the sign hangs level.
  • the loop line or string ladder 10 illustrated in Figure 1 comprises a pair of strings or cords 12, 14 joined at equal intervals by knots 16.
  • cords 12, 14 is a limp monofilament or is braided, twisted or woven preferably by braiding from a polymer fibre such as polyester fibres. It may be desired, for increase of tensile strength, to incorporate metal fibres such as thin stainless steel fibres into the braided, twisted or woven construction.
  • the cords 12, 14 are joined together at equal intervals along the in length by knots 16, as part of the braiding or weaving process, to form a string of loops. Alternatively, the cords can be tied to form equispaced knots 16.
  • knots 16 should be braided, woven or tied in a manner whereby the knots are upset from and stand out from the loop line such that the knots can be easily felt by the user during installation and use of the loop line.
  • the lower proximal end of loop line 10 terminating at knot 16 a is inserted through grommet 20 formed in a corner of sign 22 and the distal end of string ladder 10 passed through the loop formed between knot 16 a and the adjacent knot 16 and drawn tight to form a "hitch".
  • a hitch is desirable in that it is easily formed to secure itself and can be readily removed for re-use by retracting the line through the loop.
  • a first loop line 10 is attached to corner 24 of sign 25 through grommet 20 in by a hitch the manner illustrated in Figure 2 .
  • a loop 26 at the upper distal end of string ladder 10 formed by upper knot 16 b is attached to ceiling support or attachment means such as a split ring 30 connected to a magnet anchor 32 such as described in U.S. Patents No. 6,394,873 and No. 6,422,622 , incorporated herein by reference.
  • a second loop line 10 a is attached to an opposite corner 35 of sign 25 and a number of knots 16 equal to the number of knots in loop line 10 counted from lower proximal end knot 16 a to distal end knot 16 b for attachment of split ring 30 of magnet anchor 32 to the loop 26 formed by knot 16 b .
  • the two loop lines from knot 16 a to knot 16 b are the same length and, since it is not necessary to tie knots, the sign hangs level.
  • the sign can then be easily installed by lifting the magnet anchors 32 by means of the installation pole described in U.S. Patent 6,422,622 .
  • Figure 4 illustrates a ceiling-tile rail 50 attached level to a ceiling for installation of a drop ceiling.
  • a plurality of loop lines 10 are passed through spaced-apart holes 52 in rail 50 and the distal ends 54 passed through loops 56 at the proximal end, as described with reference to Figures 2 and 3 .
  • An equal number of knots 58 are counted to a loop at the distal end 54 of each line for hanging of the loop on a securing means such as a ceiling hook 60. Since no knots need to be tied, the rails will hang level.
  • Figure 5 shows a hammer 70 exemplary of a tool, hung from a hook 71 on a wall or ceiling.
  • the proximal end 72 of the loop line 74 having a plurality of equispaced knots 82 is wrapped around the hammer head 76, or through a hole 78 in the handle, and the distal end 80 passed through the loop formed by knot 82 at the proximal end of the line to secure the hammer by a hitch.
  • the loop line is hung on a loop at the opposite distal end formed by knot 82 a .
