Definitions

  • FIGS. 2OA and 2OB are schematic views of the release and locking levers of the locking mechanism of the work station of FIG. 15 in the locked and unlocked conditions, respectively.
  • the amount of lift force necessary to move the movable part 14 is a function of the tension of the extension springs 22, which acts a counter weight for the movable part 14. If the tension force of the extension springs 22 is increased, less lifting force will be necessary to move the movable part 14 along its vertical range of motion along the fixed column 12. If the tension force of the extension springs 22 is decreased, more lifting force will be necessary to move the movable part 14 along its vertical range of motion along the fixed column 12.
  • the plunger 82 slides within a hole 88 of the movable part 14 (and within any corresponding holes in the work surface and/or mounting platform if necessary) so that the plunger may have access to the plurality of holes 80 in the fixed column.
  • the plunger may also be spring-loaded so that the natural position of the plunger is to protrude through the hole 88 of the movable part and into one of the plurality of holes 80 in the fixed column.
  • Each of the holes 80 in the fixed column 12 may correspond with a vertical location in which the movable part and work surface can be locked in placed.
  • a user presses the release lever 84, which actuates the cable 86 by pulling on it.
  • the cable 86 is strung within the work surface and/or mounting platform so that when the release lever 84 pulls on the cable 84, the cable 84 pulls the plunger 82 out of the holes 80 against the force of the spring.
  • the movable part 14 and its attached work surface 16 is now permitted to slide in a vertical direction along the fixed column (i.e., the moving position).
  • the lift force adjuster 220 may comprise at least one extension spring 222, preferably two, mounted on the fixed column by an adjustable bracket 224 at a first end, as seen in FIG. 17A, and attached to a movable bracket 226 at a second end, as seen in FIG. 17B.
  • a cable 258 is attached to the movable part 214 at one end and attached to the movable bracket 226 at the other.
  • the cable 258 is also fed through or engaged with an upper pulley 256, a middle pulley 260, an intermediate pulley 261 and two bottom pulleys 262.
  • the stationary component 228 also includes a retainer body 254, wherein the upper pulley 256 is rotatably attached to the retainer body 254 of the adjustable bracket 224 as seen in FIG. 18A.
  • the cable 258 is engaged with the upper pulley 56.
  • the cable 258 then engages the upper pulley 256, and is lead downward towards the movable part 14 as best seen in FIG. 17B.
  • the cable may be attached to the movable part 214 by a screw, a rivet, or other suitable mechanism.
  • the movable part or shuttle 214 moves within a vertical range of motion along the fixed column 212, for example, the movable part 214 may translate up and down within a range of about 16 inches. Of course, any suitable distance is contemplated within the invention.
  • the motion of the movable part 14 is fixed by bearings and rails, as described in relation to FIGS. 5 and 7A-7B. There are sets of fixed and floating bearings attached to the movable part that slide within square rails that are incorporated into the fixed column 212.
  • the locking lever 304 is made to pivot through the use of a release lever 308 and a cable 310.
  • the cable 310 is attached to the release lever 308 at one end and to a proximate end 316 of the locking lever 304 (the end upon which the second protrusions are not mounted) at the other end.
  • the release lever 308, in turn, feds through a hole 314 in the mounting platform 274 and/or the work surface 216.
  • the release lever 308 is spring-loaded such that the release lever 308 is configured to be pushing inward (toward the left in FIG. 20A) so that the proximate end 316 of the locking lever is moved to the left.
  • the distal end 318 of the locking lever is swung to the right, thus causing the second protrusions to engage with a portion of the first protrusions, as seen in FIGS. 19A and 2OA.
  • the locking lever holds the mounting platform 274 and the work surface 216 as the mounting platform 274 and/or the work surface abut against the locking lever 308 due to the locking lever's protrusion through the hole 314.
  • the entire work station including the lift mechanism can be made with conventional manufacturing methods such as extrusions, sheet metal forming/bending, etc., as well as with standard materials, such as metal, plastic, and/or the like.

Abstract

Le poste de travail de l'invention peut comprendre un mécanisme de levage comprenant: une colonne fixe et une pièce mobile qui se déplace dans une plage de mouvement verticale, le long de la colonne fixe; et une surface de travail fixée à la pièce mobile. Le poste de travail peut comporter: un dispositif de réglage de la force de levage qui règle la force de levage à un niveau nécessaire pour déplacer la pièce mobile dans la plage de mouvement verticale; un indicateur de la force de levage qui indique le niveau de la force de levage fixé par le dispositif de réglage de la force de levage; et/ou une ou plusieurs premières protubérances installées sur la colonne fixe, et un mécanisme de verrouillage présentant plusieurs secondes protubérances articulées en rotation à la pièce mobile pour s'apparier à une partie des premières protubérances.
