Definitions

  • Shelving units are movable along guide rails between selected end portions by means of a lever swingably mounted on a side of each unit and having a lower end portion engageable with selected, variably positionable abutments projecting laterally from one of the rails and an upper end portion providing a hand grip for swinging the lever about its pivot to move the unit by a leverage action.
  • the pivot point of the lever is adjustable along the lever to provide variable leverage.
  • the present invention relates to an arrangement for moving each of a number of shelving units and the like on rails between two end positions by means of a lever which is pivotally mounted on a wall of each shelving unit and is swingable between two limit stops.
  • the upper end of the lever is formed as a hand grip and the lower end is designed to cooperate with abutments on one of the rails supporting the units.
  • An object of the present invention is to provide a particularly simple and reliable arrangement whereby a shelving unit is movable through an unlimited distance and at the same time an entire group of units can be set in motion with great ease.
  • a lever is swingably mounted on a side wall of each unit and has a lower end portion engageable with abutments projecting laterally from one of the rails supporting the units and an upper end portion providing a hand grip for swinging the lever about its pivot to move the unit by a leverage action.
  • the arrangement is such that, without any construction changes, it can be adapted to ditlerent leverage requirements.
  • the abutments are so positioned along the rail that the lower end of the lever in both end positions of each shelving unit lies against an abutment.
  • the invention consists in a further reduction of the force required for putting the shelving unit in movement and in a significant improvement of the movement characteristics of the unit in comparison with the rst mentioned arrangement, and in a significantly simpler and more reliable arrangement than by the last mentioned known arrangement. Moreover, there is the important advantage that depressions in the base cannot affect the engagement relationship between the lever and the abutments and that the engagement relationship is determined in the production of the apparatus and is hence independent of the construction and the installation of the shelving units.
  • FIG. 1 is a schematic front view of a number of shelving units
  • FIG. 2 is a front view showing a portion of one unit with a lever mounted thereon
  • FIG. 3 is a section on the line III- III in FIG. 2, and
  • FG. 4 is a cross section of a rail with an abutment shown in the form of a pin.
  • the shelving units 1, 2, 3 and 4 shown in FIG. l are provided with wheels 5 which run on a set of guide rails 6 mounted fast on the floor.
  • Each shelving unit is provided with a lever 7 which is swingable about a shaft 8 mounted on a wall of the unit. Movement of the lever is limited by stop members 9 mounted on the wall of the unit.
  • On one rail 6 there are eight variably positionable laterally projecting pins 11-18. With the shelving units in the positions shown, the respective levers 7 are in engagement with their pins 11, 13, 16 and 18.
  • FIG. 2 A suitable construction of the lever 7 is shown in FIG. 2.
  • the lever consists of two steel tubes 21 and 22, the opposite ends of which are welded together.
  • the upper end of the lever is provided with a hand grip 23.
  • the tubes 21 and 22 run parallel to one another and on this portion a bearing assembly comprising two bearing plates 24 and 25 (FIG. 3) is slidably mounted.
  • the plates 24 and 25 are provided with concave edge portions which embrace the tubes 21, 22 and are so designed that upon being drawn together by means of screws 26, the bearing plates are clamped fast on the ltubes 21, 22 comprising the lever 7.
  • the lever is rotatably supported by a shaft 8 which is fixed on a mounting plate 27 for mounting it on the wall of the shelving unit. Since the shaft 8 is slidable with reference to the lever 7 and canbe fixed in selected position, identical levers can be used for different types of shelving units which require a different leverage force, it being only necessary to position the mounting plate 27 and the bearing plates 24, 25 in proper positionon different types of shelving units.
  • a spring 28 is arranged between the lever and the wall of the shelving unit so as to bias the lever to a vertical position.
  • the lever is swingable out of the vertical position in either direction against spring action. Thereby the risk is avoided that the lever assumes an incorrect position when the shelving unit is moved to its respective limit position without use of the lever.
  • FIG. 4 A cross section of a suitable form of the rail 6 is illustrated in FIG. 4. 1t is shown as comprising a U-shaped iron rail mounted on a support member shown as a wood ledge 29.
  • the pins are cylindrical and are mounted in holes through side portions of the rail 6 and through the ledge 29 and secured by nuts 30.
  • the position of the lower end of the lever 7 is shown in broken lines.
  • a mechanism manually operable to effect movement of said units along said guide rails comprising a lever swingably mounted on each of said units to swing about an axis extending transversely of said guide rails, said lever having a lower end portion adjacent a rail and a manually engageable upper end portion extending up above said axis for manually swinging said lever about said axis, an abutment associated with each said shelving unit cooperative with means extending axially along one of said guide rails for releasably holding individual ones of said abutments in variably selected positions wherein same project laterally from said rail and engage with said lower 4end portions of respective ones of said levers to effect movement of said shelving units along said rails when said levers are swung about their axes.
  • Mechanism according to claim 1 in which said lever is swingably mounted on said unit by means comprising a shaft ixed in selected position on a wall of said unit, bearing means slidably on said lever in a direction lengthwise of said lever and means for securing said bearing means in selected position on said lever, whereby the effective leverage of said lever is selectively varied.
  • Mechanism according to claim 1 comprising spring means for resiliently biasing said lever to a vertical position, said lever being movable in either direction out of said vertical position against the action of said spring means.
  • Mechanism according to claim 1 in which means is provided for limiting the swing of said lever and in which said abutments are positioned on said rail to be in engagement with said lever when said lever is in a limit position and said unit is in an end position.
  • each :aid rail comprises a support member and a rail of inverted U-shape fitting over said support member with side portions on opposite sides of said support members, and in which each of said abutments on at least one rail comprises a pin extending through said side portions and through said support to secure the rail to the support and having an end portion projecting laterally of said rail and engageable by said lever.
