Definitions

  • the present invention relates to a particular type of ejector applicable to drawers for furniture and the like basically consisting of two elements that are slideable in relation to one another, one inside the other. Said elements that are slideable within one another being moved by a spring through possible compression or traction. The movement thereof being controlled by a "cam” provided with a protruding pawl that slides in a suitable groove obtained in the internal slideable element and applied within a housing cavity made on the external slideable element.
  • ejection or shock absorbing systems are known above all for opening and closing drawers, they are made of an extensive plurality of pieces and have significant constructional complication.
  • An example of this are the various types of system consisting of electric motors that eject the drawers for a few centimetres in a known and complex manner, complex inasmuch as these systems need to be connected to the main power supply, the use of motors and reduction gears for said motors, the installation thereof, which is also very complex, and the consequent reliable operating reliability. Equally, the ejection stroke is short and not always effective from the point of view of extracting the drawer.
  • the object of the present invention is therefore to surmount the aforesaid known drawbacks and this is achieved through the present ejector that is the object of the present invention.
  • the ejector 1 consists of a tubular element, preferably with a square external section 11, which contains inside itself a second parallelpipedon element 12 with a square section of dimensions that are suitable for introducing it longitudinally inside the aforesaid tubular element 11.
  • the importance of the housing cavity 121 is due to the fact that it can be considered to be divisible into two zones, i.e. a first hollow zone that definitively makes the ejector stroke and will be due to the rectilinear portion 121a thereof and behind the second hollow zone 121b that makes all the locking and release points of the cam 14.
  • the two portions 121a and 121b together make the cavity 121, as indicated above.
  • FIG 3 there is shown the conformation of the "cam” 14, which is formed of a circular part 141, to which a rectilinear portion 142 is joined at the part opposite which a short portion leads away that is orthogonal 143 to the rectilinear portion (142) that engages in the housing cavity 121 of the parallelpipedon element 12 as disclosed below.
  • FIG 4 Before embarking on a complete description of the ejector with traction or compression spring and of the operation thereof reference is made to figure 4 in which the various movement steps are shown, which are moreover known, of the cam 14 with the portion 143 thereof within the cavity 121 of the parallelpipedon element 12, which are divided into 8 steps.
  • step 2 Starting from the position that corresponds to step 1, in which the ejector keeps the possible drawer in the closed position, to the other step 2 that is obtained after brief pressure on the drawer that transmits the short movement to the ejector and moves the cam 14 and the portion thereof 143 to a first unhooking position of the portion 143 from the anchoring provided in the housing cavity 121 (portion 121b).
  • step 3 After determining, in step 2, the unhooking of the portion 143 of the cam 14 the step 3 is passed through in which said portion 143 will slide for a further short portion (121b), and will then pass to step 4, in which the portion 143 will start to slide within a portion of fairly long horizontal housing cavity (portion 121a), the length of which will be equal to about the ejection length that will be determined in step 5.
  • step 5 At the end of the step 5 the drawer is expelled completely for the entire length of the ejector.
  • step 6 In order to obtain the closing of the drawers, there is a change from step 5 to step 6 in which it is seen that the portion 143 of the "cam” 14 will travel back along the path made for the entire horizontal portion 121a of the cavity of the parallelpipedon element 12, then step 7 is embarked upon, in which the portion 143 of the "cam” 14 will start to rise within the portion 121b of the cavity 121 along a suitably tilted plane at the end of which the step 8 is obtained that enables position 1 of step 1 to be returned to, i.e. closing of the drawer.
  • a hand is schematised that approaches and rests on the front portion of the drawer C and moves the element 12 of the ejector 1 for a few tenths of a millimetre in order to apply thereto moderate pressure that will move the portion 143 of the "cam" 14 inside the housing cavity 121 (portion 121b) to a position in which by releasing the drawer, i.e. by removing the pressure from the front of the drawer, the latter will start to exit, i.e. the extraction of said drawer (step 2) will commence.
  • position 3 shows the hand that moves away and the element 12 (step 3) will start to slide in a first short portion (portion 121b), controlled by the portion 143 of the cam 14 that slides in the housing cavity 121 (portion 121b) of the element 12 and thus in the consequent position.
  • position 4 and 5 steps 4 and 5
  • the element 12 will start to slide within the tubular element 11 to the end of the housing cavity 121 (portion 121a) of the element 12, and the drawer C will then be ejected completely,
  • the joining or detaching element between the drawer and the ejector may consist of a magnet Ma as in the illustrated figures or of elastic hooking systems of known type that are illustrated and not numbered in the attached figures.
  • the length of the ejection stroke of the drawer or of any element to which the ejector is applied is made and due to the cavity part 121a of the cavity 121 and it will be this (121a) that by varying the length thereof will vary the ejection length.
  • Figures 6 and 8 show that the ejector 1 "will work" with a traction spring M1, said application system will be less “thin” than the previous one, but shorter and with the same operating principle will achieve a greater ejector stroke than the compression ejector.
  • the aforesaid system thus enables ejectors 1 to be made with limited costs through the use of a smaller number of pieces, with consequent significantly lower manpower costs, in addition, the ejectors thus made will be of significantly reduced dimensions and be applicable to positions and to solutions where traditional ejectors cannot be used.
  • the main and significant final advantage is a significant increase in the ejection stroke, which is not obtained with conventional ejectors as the space that is obtainable from the cam is limited.
