Definitions

  • the present invention relates to hinges used for household appliance doors, and in particular to a braked hinge for a door rotating around a horizontal axis.
  • a dishwasher door Specific reference will be made in the following to a dishwasher door, while it is clear that what is being said is also applicable to other types of household appliances such as ovens, washing machines, etc.
  • a dishwasher door is usually hinged to the machine frame along its bottom side through fixed fulcrum hinges, constructionally simple and particularly reliable, that often also have the function of "balancing" the door by means of slide pads used as brakes.
  • the hinge is able to hold the door at any intermediate position between the closed position and the open position thanks to the friction exerted by said pads against suitable guides.
  • the object of the present invention is to provide a hinge which overcomes said drawbacks. This object is achieved by means of a hinge having the characteristics disclosed in claim 1. Other advantageous features of the present hinge are disclosed in the dependent claims.
  • a first important advantage of the hinge according to the present invention stems from the fact that it can provide the required hold to the door without the need for a separate holding spring. As a consequence, the holding spring mounting step is dispensed with since the function of said spring is integrated into the hinge.
  • a second significant advantage of said hinge is the ease of mounting on the door in that, thanks to the integrated spring, it takes automatically and naturally the correct mounting position.
  • a further great advantage of this hinge is that the slide pads are assembled into the hinge without using rivets or the like, whereby it is possible to use also a soft material having a high friction coefficient without risks of malfunctioning of the hinge. In fact, the operating pressure is distributed over a larger area so as to decrease the specific local pressure.
  • Still another advantage of the present hinge is its structural simplicity, since a lower number of parts assembled through 3 pins only allows for an automatic or semi-automatic assembling, which reduces the manufacturing cost and assures a high reliability.
  • a hinge conventionally includes a first bracket 1, integral with the door, that is pivoted onto a second bracket 2, integral with the structure of the household appliance, through a first pin 3, while a second pin 4 provides the pivoting on bracket 1 of a tie-rod 5, which transmits the door movement to the resilient hold and brake members.
  • the novel aspect of the present hinge resides in the number and arrangement of said resilient members and of the other members cooperating therewith.
  • tie-rod 5 i.e. the end toward the inside of the machine
  • a perpendicular flange 5a in which there is formed a hole 5b suitable to engage a corresponding peg 6a formed on the rear face of a hollow vertical body 6, which is provided with three horizontal spindles 6b on the front face thereof.
  • the group of members 6-10 is housed in a double-guide member 11, provided with slide surfaces 11 a for pads 7 and with a front abutment 11 b for the spring guide 10.
  • Surfaces 11 a are substantially horizontal and preferably slightly converging to the front, as illustrated in figs. 1 and 2.
  • This double guide 11 is also pivoted onto the second bracket 2 through a third pin 12, while the rear abutment that retains members 6-10 within the double guide 11 is flange 5a of tie-rod 5. Moreover, for a greater stability of the hinge, in the side of the pad holder 6, of the spring guide 10 and of the front abutment 11b facing tie-rod 5 there are preferably formed seats suitable to receive said tie-rod 5.
  • the exact shape of the other members such as tie-rod 5 or double guide 1 can be changed if need arises, for example by forming the seats for springs 9 into the double guide 11 and thus dispensing with the spring guide 10.
