Definitions

  • the present invention relates to an improved method for makung baskets for freezer appliances, particularly for domestic deep-freeze appliances of the upright or cupboard type.
  • baskets of this type are substantially composed of a lower and an upper peripheral frame, both made of metal rods, and groups of mutually intersecting wires of suitable configuration extending between said frames.
  • the manufacture of such baskets usually starts with the formation of two groups of mutually intersecting parallel wires which are welded to each other so as to form a grid, with the wires projecting beyond at least three sides thereof by a certain length.
  • the bottom frame is subsequently welded to the thus formed grid, whereupon the projecting portions of the wires are bent upwards so as to form respective sidewalls of the basket.
  • This bending step has to be carried out with considerable precision, because the upper peripheral frame consisting of a suitably pre-formed metal rod and closed by welding the ends of the rod together, has to be welded to the free ends of the bent wires.
  • the basket is subsequently subjected to a plastic-coating treatment. This treatment is carried out in an automatic manner, employing a tunnel installation operating on the dip- coating principle. As generally acknowledged, such installations should be utilized in the most efficient manner for achieving economical operation on an industrial scale.
  • this object is attained by a method for making baskets for freezer appliances, in which at least two groups of mutually intersecting metal wires are welded to each other so as to form a planar grid, with the wires projecting beyond at least three sides of the grid by a certain length, a respective metal rod member being subsequently welded to the ends of the wires on each side of the grid beyond which the wires project.
  • the projecting wires are subsequently bent out of the plane of the grid so that the ends of the metal rod members cooperate with one another to form an upper peripheral frame of the basket, the latter being subjected to a per se known plastic coating treatment prior to the bending of the projecting wires.
  • the manufacture of a basket for a freezer appliance starts with providing two groups of metal wires 6 and 7 having a diameter of for instance 2.3 mm and a predetermined length.
  • the wires of the two groups 6 and 7 are arranged in a per se known manner so as to intersect one another, and subsequently welded to each other to form a planar grid generally indicated at 8, with the wires 6, 7 projecting beyond respective sides of grid 8.
  • a respective metal rod member 9 having a diameter of for instance 5.3 mm is then welded to the ends of wires 6, 7 on each side (at least threesides) of grid 8 beyond which wires 6 and 7, respectively, project.
  • rod members 9 extend substantially parallel to respective sides of grid 8 and have predetermined lengths selected in view of the desired dimensions of the upper frame of the finished basket.
  • a conventional peripheral bottom frame 10 is welded to grid 8, in particular to wires 6 thereof, as shown in fig. 3.
  • Frame 10 is formed in one piece of a metal rod similar to that employed for rod memebrs 9.
  • wires 7 are preferably retainedat a small spacing from frame 10 in a per se known manner.
  • the ends of rod memebrs 9 are suitably formed for instance as shown in figs. 3 to 5 in a manner enabling them to cooperate with one another for forming an upper peripheral frame of the finished basket in a manner to be described.
  • the basket which is still of substantially planar configuration, is subjected to a conventional plastic coating treatment, with the advantage that the respective equipment is utilized in an optimum manner as compared to the known method in which the plastic coating treatment takes place with the basket already in a three-dimensional configuration.
  • wires 6 are bent by an angle of about 90° adjacent bottom frame 10, while wires 7 are formed with a double bend inwards of bottom frame 10 and thereabove, so that two opposite sides 11 of bottom frame 10 are left free to slide between opposite guides (not shown) of the freezer appliance for which the basket is intended. It is to be noted that experiments have shown that the bending operation does not in any manner affect the plastic coating of the basket.
  • angular clamping members 12 are preferably of inverted U-shaped cross-sectional form provided with longitudinally extending ribs 13 for resiliently engaging the contacting end portions of two adjacent rod members 9.
  • connection of rod members 9 may of course be accomplished in a different manner as required. In the same manner the method described may be modified within the scope of the appended claims.
  • the method according to the invention is particularly efficient and versatile for employ on an industrial scale, as - in addition to the already noted advantages - the various steps can be carried out at differetn times and places.
  • the baskets may for instance be advantageously stored and/or shipped to their destination subsequent to the plastic coating treatment, i.e. in a state of reduced volume, to be readily finished at their destination in the manner described.
