Definitions

  • the present invention relates to a shelf support system which is suitable for assembly by amateurs or professionals in order to support a shelf on a wall or similar vertical support surface by means of a horizontal shelf support arm which extends from the wall or similar vertical support surface at right angles and engages with a vertically extending support bar fixable to the wall or similar vertical support surface.
  • the shelf support arm can be moved .into an infinitely variable number of positions up and down the vertically extending support bar.
  • the invention is an improvement over various systems on the market, which consist of two or more vertically disposed wall bars which are perforated along their length with one or more lines of slits.
  • Two or more shelf support arms are used for supporting the shelf.
  • Each shelf support arm has hook-shaped extensions which engage in the parallel slits in one wall bar so that the shelf support arm is held horizontal and at right angles to the wall.
  • This known type of shelf support system is difficult to align, since each of the wall bars must be affixed to the wall so that the supporting slits are in precise horizontal alignment, an adjustment not easy for the average D.I.Y. practitioner.
  • Such perforated bars have the further disadvantage that the support arms can only be adjusted from slit to slit in steps.
  • the shelf cannot easily be adjusted by less than the interval between successive slits.
  • the slit bar is not elegant in appearance, and the slits tend to gather dust, which is a disadvantage in" the home or office.
  • a shelf support system comprising a shelf support arm adapted to be mounted horizontally and a support- bar adapted to be disposed vertically and means for mounting the support bar to a vertical wall or other support surface, sliding means enabling the arm to slide up and down the support bar and retaining means to secure the support arm to the support bar at any desired position, the retaining means including a resiliently expandable member held by the support arm so as to be frictionally engageable with the support bar by operation of actuating means to expand the resiliently expandable member towards the support bar.
  • the resiliently expandable member may take the form of a deformable but resilient plug with an aperture therein to receive a screw or bolt whereby with progressive insertion of the screw or bolt into the aperture the plug is caused to expand towards the support bar to a sufficient extent as to secure the support arm in a desired position.
  • the said aperture may be in the form of a slit.
  • the resiliently expandable member is held in a recess in the support arm.
  • the screw or bolt may be insertable into the plug aperture from above downwards into the plug in the support arm or the screw or bolt may be insertable into the plug aperture in a lateral or oblique direction.
  • one end of the support arm terminates as a channel section to slidingly engage the ends of the cross members of a generally "T"- shaped sectioned support bar.
  • the support bar may have cross-sections of various shapes but desirably the shape of the end of the support arm adapted to engage the support bar will be shaped in a corresponding manner.
  • the support bar may be formed by extrusion.
  • the support bar may be provided with holes therein to enable it to be screwed or bolted to a vertical support wall.

  • the plug 6 has a slit 9 typically extending for three quarters of its height, and a recess 11 to accept the head of a screw 10.
  • the plug 6 with the slit 9 in its unexpanded state as seen in Figure 5 slides easily into its housing in the support arm 1.
  • ⁇ " ? ⁇ en a suitable screw 10 is screwed into the slit 9, the slit 9 becomes widened and the plug 6 expands into a configuration as shown in Figure 6.
  • Figure 2 shows that the plug 6 in its expanded position presses against the wall-mountable support bar 5 and simultaneously draws the inside faces of the internal flanges 3 against the rear faces of the lugs 4.
