Definitions

  • the invention relates to rivet removal tool.
  • Retail refrigeration units often comprise ticket rails affixed to the customer-facing edges of the shelves thereof, in order that product and pricing information can be provided to the customer.
  • These ticket rails are often formed from a strip of metal which is riveted onto the customer-facing edge of the shelf.
  • a spacer washer is often placed between the ticket rail and the edge of the shelf, in order to create a fixing point which will hold a shelf edge riser.
  • Shelf edge risers are typically made of a transparent material (e.g. Perspex), with channels cut into them to enable them to be slotted over fixing points on the customer-facing edge of the shelf, for example the spacer washer of a ticket rail fixing point.
  • Removal of the ticket rails is often required in order to refurbish a refrigerator and, more recently, in order to fix air guiding products to the shelf.
  • the present invention provides a rivet removal tool, comprising: a first plate and a second plate disposed in a parallel facing orientation; and a separation mechanism adapted to move the second plate relative to the first plate such that a distance between a face of the second plate and an opposing face of the first plate is varied while the parallel facing orientation of the plates is maintained, wherein the first and second plates comprise corresponding slots extending from a first edge of each plate in a direction towards a second, opposing edge of the plate.
  • the first and second plates can receive the shaft of a rivet by insertion of the shaft into the slots.
  • At least one of the slots may have a diameter which is less than the diameter of the head of the rivet, so that the shaft is receivable into the slot while the underside of the rivet head contacts an outer face of the plate (the inner face of each plate being that which faces towards the other plate, and the outer face of each plate being that which faces away from the other plate).
  • the outer face of one plate contacts the underside of the rivet head, and the outer face of the other plate contacts the shelf edge. Increasing the distance between the plates therefore acts to pull the rivet out of its fixing hole in the shelf edge, thus removing the need to drill the rivet out.
  • the rivet attaches a structure such as a ticket rail to the front edge of the shelf
  • the outer face of one plate contacts the ticket strip and the outer face of the other plate contacts the shelf edge.
  • Increasing the distance between the plates therefore acts to pull the ticket rail away from the shelf edge, and thus pull the rivet out of its fixing hole in the shelf edge.
  • the present invention spreads the loading evenly across the outer face of the plate which sits flat against the shelf edge, therefore reducing the likelihood of bending and damaging the shelf edge (as could happen with a crow-bar or pry-bar, which would exert pivoting pressure to one side of the rivet and in a small area on the face of the shelf).
  • the separation mechanism comprises a screw thread coupled to the first plate, wherein the screw thread is coupled to the second plate by way of a corresponding thread, the first and second plates being adapted so as to prevent rotation of the second plate relative to the first plate upon operation of the screw thread.
  • the first plate comprises a first shaft extending from the outer face thereof
  • the second plate comprises a second shaft extending from the inner face thereof.
  • the first plate comprises a through-hole connecting an inner surface of the first shaft with the inner surface of the first plate.
  • the second shaft is slidably received into the first shaft, and the second and first shafts are adapted so as to prevent rotation of the second shaft relative to the first shaft, e.g. by way of a protrusion on the inner surface of the first shaft which is receivable into a corresponding channel extending in a longitudinal direction along the outer surface of the second shaft (or vice versa), or by virtue of the inner surface of the first shaft and the outer surface of the second shaft having corresponding polygonal cross-sections (e.g.
  • a male screw thread may be receivable into the first and second shafts, wherein the inner surface of the second shaft comprises a corresponding female screw thread for receiving the male screw thread.
  • the male screw thread is coupled to the first shaft such that longitudinal movement of the male screw thread relative to the first shaft is prevented, e.g. by way of a protrusion on the inner surface of the first shaft which is receivable into a corresponding channel extending around a circumference of the male screw thread (or vice versa). Rotation of the male screw thread thus causes the second shaft to move in a longitudinal direction relative to the first shaft, and thus causes the distance between the inner face of the second plate and the inner face of the first plate to be varied.
  • the screw thread may comprise a connector which is adapted to receive a ratchet (also known as a ratcheting socket wrench).
  • a ratchet also known as a ratcheting socket wrench
  • the screw thread may be a screw thread of a hex-headed screw, the head of which can receive a hexagonal ratchet.

  • the connector may be adapted to receive a driver bit of a drill or screwdriver.
  • the drill or screwdriver may be an electric drill or electric screwdriver.
  • the drill or screwdriver may be a mechanical drill or mechanical screwdriver. In the case of a mechanical screwdriver, the driver bit may be a tip of the screwdriver.

  • the separation mechanism comprises the pin, the track and the pivot.
  • the first plate may comprise a first shaft extending from the outer face thereof, and the second plate may comprise a second shaft extending from the inner face thereof.
