Definitions

  • the present invention relates to a closing device for sports footwear, in particular for ski-boots.
  • the invention also relates to a method for manufacturing said closing device.
  • a rack is mounted on one flap, and a lever on the other flap, said lever consisting of an arm and a forked lug able to engage with the teeth of the rack so as to ensure closing of the boot.
  • Steps have also been taken to develop the design of the closing lever.
  • Magnesium and silicon are the main components in an alloy. Other important components are copper, which plays a part in the ageing process, and manganese and chromium (only in the case of the 6005 A series) for control of recrystallization.
  • These categories of alloys have a high degree of hot deformability and may have an increased mechanical strength following suitable heat treatment which causes the formation of hardening phases which are homogeneously dispersed in the aluminium matrix.
  • These alloys may be used to obtain fasteners which are characterized by an average surface hardness of 60 HB (maximum 80 HB) and an average tensile breakage strength of 170 N/mm 2 (maximum 270 N/mm 2 ).
  • ski-boots which are characterized by closing levers which have increasingly smaller thicknesses and weight, while the mechanical properties of these alloys are such that it is not possible to reduce the thicknesses beyond a certain limit in order to guarantee their strength.
  • the object of the present invention is to provide a closing device which, at thicknesses smaller than those obtained with conventional aluminium alloys, has mechanical properties which are at least equivalent, if not superior to those of the known devices.
  • one object of the present invention is to provide a closing device which has, for the same thicknesses and cross-sections, a greater tensile strength than the devices obtained using conventional aluminium alloys.
  • a further object of the present invention is to provide a method for manufacturing closing devices according to the present invention which is able to reduce the manufacturing time and costs.
  • a device for closing sports footwear is indicated in its entirety by 10.
  • the closing device 10 comprises a rack 20 and a lever 40 suitable for engaging with the rack 20 in at least one position.
  • the lever 40 by means of the fixing means 90, is permanently connected to a first flap of the footwear (not shown).
  • the rack element 20 comprises a toothed portion 22 and a flat portion 24 which terminates in a widened extension 26.
  • Said rack element 20 can be fixed to a second flap of the footwear (not shown) by means of known fixing means, for example a rivet which engages inside a through-hole 28 formed in the extension 26 of the flat portion 24.
  • the lever 40 consists of a lever arm 50 and a forked lug 60 which are connected together by means of a tie-piece 70.
  • Said arm 50 which is substantially U-shaped, has a slightly curved profile in order to adapt better to the underlying upper or leg-piece of the boot. It is composed of a central body 52 and two wings 54 and 56 between which an opening 58 with parallel sides is formed. This opening 58 extends longitudinally along most of the length of the profile 50.
  • a first hole 57 and a second hole 59 ( Fig. 4 ), which have the same diameter and are coaxial with each other, are formed in the end part of the two wings 54 and 56.
  • a further pair of holes, 51 and 53 which have the same diameter and are coaxial with each other, are positioned approximately midway between the ends of the opening 58.
  • the forked lug 60 which is also substantially U-shaped and slightly curved, is composed of a central body 62 and two prongs 64 and 66 between which an opening 68 with parallel sides is formed. This opening 68 extends longitudinally along most of the length of the forked lug 60.
  • a first hole 67 and a second hole 69 which have the same diameter and are coaxial with each other ( Fig. 4 ), are formed in the end part of the two prongs 64 and 66.
  • a cylindrical shaped pin 82 is arranged inside the holes 67 and 69 and is able to engage, when the device 10 is closed, with a recess in the toothed portion 22 of the rack element 20.
  • a first hole 61 and a second hole 63 ( Fig. 4 ), which have the same diameter and are coaxial with each other, are formed in the forked lug 60 at the end diametrically opposite to the end where the pin 82 is fixed, a cylindrical pin 84 being arranged in said holes.
  • the tie-piece 70 has the function of connecting together the lever arm 50 and the forked lug 60.
  • Said tie-piece consists of a threaded sleeve 72 and an adjusting pin 74.
  • the threaded sleeve 72 which has a parallelepiped shape, is designed to be positioned inside the opening 58 of the lever arm 50 and has, about midway along its axial length, a transverse hole 77.
  • the adjusting pin 74 has a first externally threaded end 75 by means of which it may be screwed or unscrewed into/from the threaded sleeve 72, and a second end 76, where the through-hole 78 is formed. Said end 76 is intended to be seated inside a recess 79 formed in the end of the forked lug 60 with the holes 61 and 63.
  • the cylindrical pin 84 is designed to engage, not only with the first hole 61 and the second hole 63, but also with the hole 78, connecting together the tie-piece 70 and the forked lug 60.
  • the tie-piece 70 is in turn connected to the lever arm 50 via the cylindrical pin 86.
  • This cylindrical pin 86 engages with the first hole 51, the hole 77 and the second hole 53.
  • lever arm 50 and forked lug 60 via the tie-piece 70 allows the user the possibility of adjusting the length of the lever 40 by screwing or unscrewing the adjusting pin 74 into the sleeve 72 and at the same time rotating the forked lug 60 with respect to the lever arm 50, making it easier to perform the operations of closing and opening the device 10.
  • a bracket 90 with a substantially rectangular shape and curved profile is fixed in a known manner, for example by means of rivets, via the through-holes 92 and 94 to the flap of the shoe or boot which is situated opposite to that on which the rack 20 is fixed.
  • This bracket 90 has, along the two longer sides, two tapered flanges 96 and 98 which extend at right-angles to the plane of the bracket itself.
  • Two holes 97 and 99, which have the same diameter and are coaxial with each other, are provided on these two flanges.
  • a first cylindrical pin 87 engages inside the first hole 97 of the bracket and the first hole 57 of the lever arm.
  • a second cylindrical pin 89 engages inside the second hole 99 of the bracket and the second hole 59 of the lever arm.
  • the lever 40 By means of the pins 87 and 89 the lever 40 is fixed to a flap of the shoe or boot opposite to that where the rack 20 is situated.
  • the lever 40 which is able to rotate about the axis coinciding with the axes of the two pins 87 and 89, may be easily fixed by the user to the rack 20.
  • a spring 100 is provided between the lever arm 50 and the bracket 90 and allows the device 10 to be kept in the closed position once the lever 40 has been fixed to the rack 20.
  • the connection between lever 40 and rack 20 may in fact be released only by overcoming the opposing force exerted by the spring 100.
  • aluminium alloys of the 6000 series are normally used for the production of closing levers for ski-boots.
  • Aluminium alloys of the 7000 series such as the alloy 7003, are also known.
  • the main characteristic component in this alloy is zinc.
  • the alloy also contains magnesium and copper, which have a significant effect on the ageing process, and chromium and manganese, which affect the recrystallization process.
  • the present invention therefore relates to the components of a closing device 40 such as the lever arm 50, forked lug 60 and rack 20 which are made of 7000 series, in particular 7003 series, aluminium alloy. It has in fact been found that it is possible to manufacture levers which, for the same mechanical strength, are thinner than those which are conventionally available in commerce or which, for the same resistant cross-section, are able to withstand higher stresses without the risk of breakage or deformation.
  • the present invention also relates to an innovative method for manufacturing these closing levers.
  • the known method for machining the lever arm 50 envisages firstly the extrusion, through a suitably shaped die, of an aluminium billet which is made of a 6000 series alloy.
  • This extruded bar 50a which may have a length also of several metres, has a width equal to the width of the finished component 50 which is to be obtained.
  • the hinging pins 86, 87 and 89 of the lever arm 50 described above will be arranged inside these holes.
  • the extruded bars 50a are then machined automatically by means of milling cutters 110.
  • These tools 110 which perform stock-removal machining operations, allow the finished component 50 to be cut from the extruded bar 50a. Once the finished component 50 has been cut, the milling cutters 110 cause feeding of the extruded bar 50a by the amount needed to perform cutting of the next component.
  • the components thus obtained may be already finished or, if required, may undergo further machining operations such as blanking, bending and coining.
  • the present invention relates to a method for manufacturing the individual components of a closing device 10, which are made of a 7000 series aluminium alloy, said method not involving the use of the milling/sawing operations described above.
  • the semifinished parts obtained by means of extrusion of a 7000 series aluminium alloy may be blanked, bent and coined in a single operation using special dies 120 (see Figure 6 ).
  • the reference number 50b ( Fig. 6 ) denotes the semifinished part from which a lever arm 50 is subsequently obtained
  • 60b Fig. 10
  • the reference number 50b denotes the semifinished part from which a forked lug 60 is subsequently obtained.
  • the rack 20 is made by means of a method which is similar to that performed for the lever arm 50 and the forked lug 60.
  • the manufacture of the semifinished parts 50b, 60b is performed in a manner which is substantially identical to that described for the known method for manufacturing closing levers.
  • the semifinshed part 50b, 60b obtained by means of extrusion is positioned on the blanking press (not shown).
  • the dies 120 which reproduce the profile and the shape of the component which must be produced, are formed by a bottom shell 123 and a top shell 122.
  • the bottom shell 123 during the stamping/blanking operation remains stationary, while the top shell 122 performs an alternating movement in a direction Fp which is perpendicular to the working plane of the blanking press.
  • the top shell 122 coming into contact with the bottom shell 123, deforms the part of the semifinished article 50b, 60b which is situated between the two shells 123, 122 and causes blanking and separation of the finished product 50, 60 from the semifinished part 50b, 60b.
  • the components to be machined are lubricated with suitable oils in order to facilitate machining and prevent the stamped/blanked components from getting stuck inside the die 120.
  • the finished component 50, 60 is not only blanked, but, if required and obviously if the die 120 is suitably shaped, may also be bent and shaped.
  • lever arms which have a perimetral profile s which is shaped with curved lines or obtain eyelets 152 in the region of the central body 52 of the lever arm.
  • Said eyelets 152 may have both a weight-reducing function and aesthetic function for the finished component.
  • the working time needed to perform the blanking operation by means of the die 120 is decidedly shorter, also in the case of simple components for which shaping is not required, compared to the working time needed to perform the milling operations using the known milling cutters 110.
  • moulds 120 a further advantage of the use of the moulds 120 consists in the fact that there is a significant reduction in the amount of waste material.
  • the amount of raw material used is, however, also reduced in the case where it is required to produce components which have an external profile without a concave or convex form.
  • the component 50, 60 thus obtained is bored so as to form the holes for receiving the various hinging pins.
  • This treatment step consists in carrying out conventional T5 and T6 heat treatment operations on the individual components.
  • T5 heat treatment consists in heating to the extrusion temperature followed by artificial ageing, while T6 heat treatment consists in solution tempering followed by artificial ageing.
  • Test data are provided below solely by way of a non-limiting illustration of the present invention, these data clearly showing how use of the 7000 series alloys is advantageous compared to the conventional 6000 series alloys.
  • levers 40 are made using the same extrusion die.
  • the first lever referred to below as L1
  • L1 is made using the aluminium alloy 6005A and is subject, once the machining operations have been completed, to T6 heat treatment.
  • the second lever referred to below as L2
  • L2 is made using the aluminium alloy 7003 and is subject, once the machining operations have been completed, to T6 heat treatment.
  • the resistant cross-section referred to is the cross-section of the forked lug along the centre plane.
  • This cross-section has a resistant surface area of 70 mm 2 .
  • the tests were used to determine firstly the load at which the forked lug 60 of the lever L1 starts to deform (yield point with flattening of the curvature) and then the load at which complete elongation of said forked lug 60 occurred, with values close to breakage.
  • Table 1 Tensile test carried out on fasteners having the same resistant cross-section (Example 1) Load(N) L1 L2 1300 initial yielding of forked lug (yield point) no structural yielding 1630 complete elongation of forked lug (breakage) no structural yielding 1890 --- starting yielding of forked lug (yield point) 2280 --- complete elongation of forked lug (breakage)
  • L1 fastener with 6005A T6 alloy components - resistant cross-section 70 mm 2
  • L2 fastener with 7003 T6 alloy components - resistant cross-section 70 mm 2
  • the resistant cross-section referred to is the cross-section of the forked lug 60 along the centre plane and, in the table shown below, this cross-section will be defined as being "critical".
  • the aim of these tests is to check how much the resistant cross-section of L1 must be increased compared to the similar cross-section of L2 in order to withstand the same yield point load T.
  • the device according to the present invention has features which provide an advantageous solution to the problems and drawbacks of the devices according to the prior art.
