Definitions

  • the present invention relates to dishwasher racks, and in particular to a device which allows to change the position in height of a rack adjustable at least at two different heights.
  • Prior art devices are generally rather complicated both to manufacture and to operate, with resulting drawbacks of significant cost, poor practicality, great bulkiness and little reliability.
  • An example thereof are the so-called "push-push” type devices, wherein the change of height is achieved by pushing the rack always in the same direction, typically upwards, by means of a mechanism similar to that of knock-on pens. In this case it is easy to operate the device unintentionally while pulling out the rack, with the risk of having the full upper rack falling down on the high crockery arranged in the lower rack.
  • the operation requires the rack to be pulled out completely from the tank and/or is possible only when the rack is empty.
  • the object of the present invention is to provide a device suitable to overcome the above-mentioned drawbacks.
  • a first advantage of the device according to the present invention is its structural simplicity, which positively affects the cost, strength and reliability of the device.
  • a second advantage of the present device is its ease of operation, which allows its use with a single hand even when the rack is full and without having to pull it out completely from the tank.
  • Another advantage of the present device is to prevent the risk of unintentional descent of the rack upon its extraction.
  • the device according to the present invention is made up of three pieces only, namely a guide and support bracket 1, a plate 2 for the coupling to rack C and a latch 3 interposed between bracket 1 and plate 2.
  • bracket 1 consists of a lower elongated support la shaped like an inverted L, on which there are mounted wheels 4 for sliding on guide G, and an upper guide 1b extending vertically at the outer edge of the forward portion of the lower support la.
  • the guide portion 1b is substantially flat, but it is provided in the vertical plane with a small inwards curvature, i.e. towards the rack.
  • Guide 1b also has a vertically extending window 5 and a ramp 6, adjacent and parallel to window 5 on the inner face, ending at the top with a locking tooth 7.
  • Plate 2 is vertically slidably inserted on guide 1b thanks to its C-shaped vertical sides which enclose the vertical sides of guide 1b.
  • stops (not shown in the figures) are provided on the inner face of guide 1b and correspondingly on the outer face of plate 2.
  • the coupling of rack C to plate 2 is achieved through suitable lugs 8 formed on the inner face of plate 2. These lugs 8 are shaped almost as a quarter of a circle so as to receive and retain the horizontal metallic wires which make part of the side of rack C.
  • a seat for latch 3 is formed between the outer face of plate 2 and the inner face of guide 1b, at window 5 and ramp 6.
  • the latch is pivoted onto plate 2 at its upper end 3a, which is suitably shaped so as to snap on a horizontal rod of said plate 2.
  • the lower end 3b of latch 3 abuts on guide 1b and is accessible from the outer face through window 5.
  • the contact of end 3b with the inner face of guide 1b is guaranteed by a small leaf spring 3c, integrally formed on the back of latch 3 and abutting against the outer face of plate 2.
  • Figures 1 and 5 illustrate the "rest" condition with rack C in the lower position. In this condition, plate 2 and the lower end 3b of latch 3 abut on the horizontal surface of the support portion 1a of bracket 1.
  • fig.2 shows how the lifting of rack C takes upwards plate 2 integral therewith and latch 3 pivoted at 3a on said plate 2.
  • the lower end 3b of latch 3 meets ramp 6 and therefore moves inwards thus compressing spring 3c.
  • end 3b reaches the end of ramp 6 (fig.3), the push of spring 3c makes it jump outwards and thus engage the locking tooth 7.
  • plate 2 and therefore rack C are retained in the upper position (fig.6) by the locking tooth 7 which supports latch 3.
  • the present device is located only on the right side of rack C, nothing prevents its use on the left side with a structure which is obviously specular with respect to the above-described structure. It is also possible to provide the rack with a pair of devices, one on each side, so as to give the user the possibility of raising the rack on the right side or on the left side or on both sides.
  • the device may be easily modified so as to provide a plurality of intermediate positions between the lower position and the maximum rise position. In order to achieve this it is sufficient to form a sequence of ramps 6, 6', 6", etc. each ending with a relevant locking tooth 7, 7', 7" etc. In this way latch 3, and therefore the rack, can be locked at various heights without changes to the operation of the device.
