Definitions

  • the present invention relates to a mainly plastic lock for refrigeration appliances in accordance with the introduction to the main claim. It relates in particular to a lock for horizontal freezers.
  • Conventional vertical freezers present locks enabling the lid to be opened by a person possessing the relative key.
  • the locks currently installed on such freezers are of the cylinder type and substantially of metal construction.
  • plastic locks have been used in certain applications, such as computer disk containers, compact disk containers or liquid soap containers.
  • An object of the present invention is to provide a lock mainly of plastic construction for use with horizontal freezers, as an alternative to those of the known art.
  • a further object of the present invention is to provide a lock for horizontal freezers which is able to withstand at least a "banal" break-in attempt.
  • It comprises a support 2 which can be fixed to the lid of a conventional horizontal freezer by holes 3.
  • a projection 4 provided with a cylindrical through hole 5.
  • the hole 5 presents a first groove 6 and a second groove 7 which are disposed axially along the inner surface 5a of the hole 5 and extend radially from the hole 5. Said grooves 6, 7 are spaced apart by 90° on a circumferential arc having the hole 5 as centre.
  • Housed in the hole 5 there is a cylinder 8, well visible in Figure 5. It presents a surface in the form of a cylindrical sector 8a, which when the cylinder 8 is rotating slides along an inner surface 5a of the hole 5.
  • a portion 10 of square cross-section from which a U-shaped portion 11 extends.
  • the portion 10 of square cross-section is intended to receive an aperture 12a of similar shape, provided in a hook-shaped element or hook 12.
  • the aperture 12a and portion 10 of square cross-section render the cylinder 8 and hook 12 torsionally rigid.
  • the cylinder 8 is inserted into the hole 5, its collar or flange 8c abutting against the projection 4.
  • the cylinder 8 is axially secured to the hook element 12 by a fixing washer 13. This fixing method axially blocks the cylinder 8 within the hole 5.
  • the hook 12 cooperates conventionally with a pin (not shown) to lock the freezer lid.
  • the interior of the cylinder 8 presents a passageway 19 which opens in a side thereof of substantially square cross-section (see Figure 3), through which the key 9 is inserted, the use of which is clarified hereinafter.
  • the rocker element 15 presents a shaped profile 20 which by cooperating with a corresponding shaped profile 21 of the key 9 (comprising shoulders 21A defining a recess 21 B into which the profile 20 penetrates), centres the rocker element relative to the key 9 when this latter is inserted into the passageway 19.
  • the key 9 presents, in addition to the profile 21 corresponding to the profile 20 of the rocker element, a seat 23 enabling the rocker element 15 to move towards the key and substantially to receive it with the tooth 18 disengaged from the groove 6, 7.
  • the key 9, cylinder 8, support 2, fixing washer 13 and hook 12 are made of ABS.
  • the tooth 18 can be provide integral with the hole 5, while the groove 6, 7 can be provided in the rocker element 15.
