Definitions

  • the present invention relates to a lever fastening having the characteristics disclosed in the precharacterizing clause of the principal claim.
  • lever fastenings which, in their most common and typical configuration, comprise a base, designed to be fixed to one of the portions to be secured by means of the fastening, and a lever hinged at one of its ends on the base and connected, by means of a tie-rod , to a hook which can engage with a tooth of a rack element, which in turn is fixed to the other portion to be secured.
  • the fastening is closed by engaging the hook in one of the teeth of the rack element and subsequently swinging the lever about its hinge axis, thus moving the tie-rod and the hook and thereby bringing the hook towards the base and thus bringing the two portions towards each other.
  • the problem tackled by the present invention is that of providing a lever fastening which is structurally and functionally designed to overcome the limitations described above with reference to the cited prior art.
  • the number 1 indicates the whole of a lever fastening made according to the present invention.
  • the fastening 1 can be used to bring together, and hold together, two portions 2a and 2b of any kind of article which are at least partially movable with respect to each other.
  • a preferred, but not exclusive, example of an article to which the fastening 1 can advantageously be applied is a boot for skiing, but it can equally well be fitted to other sports footwear, skates or other articles.
  • the fastening 1 comprises a base 3, in which holes 4 are made so that the base 3 can be fixed to the portion 2a, by riveting for example.
  • a first lever 5 is hinged on the base 3 and comprises an operating appendage 6 from which there extend towards the base 3 a pair of prongs 7, hinged on the base 3 at their ends opposite the operating appendage 6, to allow the lever 5 to swing about a first axis X.
  • a second lever 10 On the first lever 5, in a position spaced apart from the axis X, there is hinged a second lever 10, also comprising an operating appendage 11, from which there extends a pair of prongs 12 hinged at their opposite ends on the first lever 5, so that the second lever 10 can swing about a second axis Y, parallel to and spaced apart from the axis X.
  • a pin 13 parallel to the axis Y and spaced apart from it, to which is rotatably fixed a tie-rod 14, which comprises a rod element 15 and a fork element 16 extending from an end of the rod element 15 remote from the second lever 10.
  • a hook 17 consisting of a pin extending parallel to the axes X and Y, this hook being capable of engaging with a rack element 20 fixed to the portion 2b.
  • the first lever 5 can swing about the axis X between a closed position, in which the operating appendage 6 lies on the base 3, and an open position, in which this appendage is located away from the base 3.
  • the second lever 10 can swing about the axis Y between a closed position, in which the operating appendage 11 lies on the first lever 5, and an open position, in which this appendage is located away from the first lever 5.
  • the prongs 12 of the second lever 10 are hinged in such a way that both of them are outside the prongs 7 of the first lever 5. Additionally, recesses 8 are formed in the prongs 7 to receive the pin 13 and a seat 18 is formed on the operating appendage 11 of the second lever 10 to receive the operating appendage 6 of the first lever 5.
  • the first lever 5 is advantageously received in and substantially concealed in the second lever thus limiting the overall dimensions of the fastening 1.
  • the pairs of prongs 7 and 11 are designed in such a way that, when both of the levers 5 and 10 are swung into the closed position, the rod element 15 of the tie-rod 14 is received between the aforesaid pairs of prongs.
  • the operation of the fastening 1 is as follows.
  • the levers 5 and 10 are initially swung to the open position (Fig. 2) and the hook 17 is engaged in a tooth of the rack element 20 (not shown).
  • the fork element 16 is suitably shaped to enclose the rack element 20 without interfering with it.
  • the first lever 5 is then swung into the closed position about the axis X (the sequence is shown in Figures 3 and 4). This swinging movement causes the second lever 10, together with the tie-rod 14 and the hook 17, to move towards the base 3, and consequently causes the two portions 2a and 2b to make a first movement towards each other.
  • the relative positioning of the axes of rotation X and Y and of the pin 13 is such that the swinging of the first lever 5 causes the hook 17 and the base 3 to move towards each other through approximately two centimetres, and the swinging of the second lever 10 causes the hook and the base to move towards each other through approximately three centimetres.
  • the fastening 1 is opened by swinging first the second lever 10 and then the first lever 5 to the open position, after which the hook 17 can be conveniently disengaged from the rack element 20.
  • the fastening 1 advantageously makes it possible to obtain a partially open state in which only the first lever 5 has been swung into the closed position.
  • the securing of the fastening can be partially released, while still maintaining a certain degree of closure.
  • the fastening 100 differs from the fastening 1 described in detail above, in that the second lever 10 is not hinged on the first lever 5 but on the end of the tie-rod 14 opposite the first lever.
  • the second lever 10 is hinged on the free end of the fork element 16 to swing about an axis Z, parallel to the axis X about which the first lever 5 is hinged.
  • the hook 17 extends between the free ends of the prongs 12 of the second lever 10, in a position parallel to the axis Z and spaced apart from it.
  • the second lever 10 is hinged on the fork element 16 in a median position, lying between the hook 17 and the opposing operating appendage 11, and swings about the axis Z between a closed position and an open position, in which the hook 17 is moved towards and away from the base 3 respectively.
  • the tie-rod 14 is connected directly by means of the pin 13 to the first lever 5, in a position parallel to and spaced apart from the axis X.
  • the distance between the prongs 12 of the second lever 10, and the distance between the hook 17 and the opposing operating appendage 11, are such that the rack element 20 can be received between these elements.
  • corresponding recesses 16a are provided in the fork element 16 to receive the prongs 12.
  • the fastening 100 can also be closed or opened by moving the levers 5 and 10 in the reverse order to that described above, thus enabling the securing forces to be divided, as a general rule, in a different way.
  • the fastening is opened by swinging the levers 5 and 10 to the open position, but in this case the order of opening can be chosen by the user.
  • this second embodiment of the invention also offers more freedom in the positioning of the hinges between the tie-rod and the levers, thus providing a more flexible solution in terms of the division of the movement, and therefore the total securing force, between the first and the second lever.
  • the pin 13 immediately behind the axis X, so that the first lever 5 has a lever ratio such that a high securing force can be developed without causing excessive fatigue to the user.
  • most of the total movement of the hook towards the base is provided by the swinging of the second lever 10, in which the distance between the hook 17 and the axis Z is therefore greater.
  • the present invention thus resolves the problem described above in relation to the cited prior art, while offering numerous other advantages, including a greater range of movement of the fastening when the portions to be secured are moved towards each other, or, for the same range of movement, the possibility of achieving the securing with a smaller force.
