Definitions

  • the present invention refers to a supporting base for a lever arm of a clamping device, particularly adapted for application to sports shoes such as for instance ski or snowboard boots or shoes, ice skates, roller skates, mountaineering boots, cycling shoes, motorcycling boots, and the like, as well as a method for making said supporting base for a lever arm.
  • Sports shoes of the above-cited kinds are largely known to usually comprise flaps that are capable of opening out, so as to facilitate the introduction of the foot in the shoe, and being then tightened together by means of at least a clamping device.
  • clamping device is generally based on the principle of a second-class lever, wherein the device comprises a lever arm pivoted about a fulcrum on a supporting base of its own, which is attached on to a first flap of the sports shoe.
  • the coupling of the lever arm to the supporting base thereof is obtained by providing an articulated joint to act as a fulcrum, wherein the lever arm is able to pivot about a fulcrum axis.
  • the lever arm is further pivotally coupled to a connecting rod.
  • This connecting rod is provided with a hook member that is adapted to selectively engage a selection tooth of a rack secured on to a second flap of the sports shoe.
  • a force is imparted to the grip end portion of the lever arm to rotate the lever arm about the fulcrum axis.
  • Such action causes the selection tooth to undergo a tractive force causing the two flaps of the sports shoe to move closer to each other until they eventually are fully tightened together to establish a closed condition of the shoe.
  • the resistance arm axis is positioned closer to the first flap of the sports shoe than the fulcrum axis, and the articulated fulcrum joint is submitted to a fastening torque.
  • the above-described clamping step is followed by a release step of the two flaps of the sports shoe from each other, to thereby completing a utilization cycle of the clamping device.
  • EP 1 922 944 discloses a supporting base for a lever arm comprising a plate, which is roughly rectangular in its horizontal plane, and having two peripheral tabs extending almost perpendicularly from the longitudinal peripheral edges of the plate, such peripheral tabs being provided with a respective bore.
  • Each such peripheral tab is provided with a bridge-like member for connecting to and supporting a further tab, which is also provided with a respective bore and having a shape roughly similar to that of the peripheral tab.
  • the bridge-like member is bent into the shape of a U, so that the inner tab is able to fit in approximately parallel to and spaced from the peripheral tab with the respective bores lying coaxial with each other.
  • Two accommodating receptacles are thus formed, each one being able to receive a respective appendix provided with a bore and protruding from a fulcrum end portion of a lever arm.
  • the bore in each such appendix lies coaxially relative to the bores in the two tabs forming the accommodating receptacle, so as to allow a hinge-like linking member, such as a rivet, a screw or the like, to be inserted therethrough.
  • a hinge-like linking member such as a rivet, a screw or the like
  • Such hinge-like linking member is supported at its end portions by the inner tab and the peripheral tab, respectively, thereby forming a kind of supported beam.
  • such accommodating receptacle is such as to cause the hinge-like linking member to be exposed to deformations, especially in the case of impacts or blows of an accidental nature against the lever arm, since the inner tab is simply resting on the plate and the bridge-like member for supporting and connecting the inner tab to the peripheral tab is of the cantilever type; in other words, a stress of an accidental nature would almost entirely concentrate at the end portion of the hinge-like linking member that is sustained by the peripheral tab.
  • the articulated fulcrum joint is vulnerable to accidental bumps, blows and impacts in substantially the same manner and to the same extent as an articulated fulcrum joint provided with a conventional supporting base having just two tabs, since the sole peripheral tabs are connected to and supported by the plate and, as a result, are capable of taking up and absorbing such accidental bumps and impacts.
  • the above-noted drawback is accompanied by another one basically due to an unbalanced constraint-related reaction of the tabs.
  • shearing and flexural stresses generated during the clamping step, as well as the fastening torque acting in the closed condition are mainly compensated by a constraint of the fixed joint type featured by each peripheral tab, rather than by a constraint of the support type featured by each inner tab.
  • the fatigue strength of the articulated fulcrum joint is comparable to that of a clamping device comprising a lever-arm supporting base provided with just two tabs.
  • Still another drawback derives from the bulkiness of the bridge-like member, which prevents the lever arm from being capable of being fully rotated by 180° during opening.
  • a sheet-metal plate to be used in view of cutting out a blank for the production of a lever-arm supporting base provided with four tabs must of course have a larger surface area than a sheet-metal plate to be used in view of cutting out a blank for the production of a lever-arm supporting base provided with just two tabs, since forming the other two tabs obviously requires additional material to be available.
  • the object of the present invention is to provide a supporting base for the lever arm of a clamping device, in particular for a sports shoe, which is effective in doing away with the drawbacks of prior-art embodiments.
  • a further purpose of the present invention is to provide an accommodating receptacle that is adapted to ensure the same type of support to each one of the end portions of the hinge-like linking member, so that any stress of an accidental nature, as imparted in particular to the lever arm, is able to distribute itself in a substantially equally apportioned manner to the end portions of the hinge-like linking member, to the benefit of a reduction in the risk of deformations.
  • Still another purpose of the present invention is to provide a supporting base for a lever arm, wherein each tab is able to perform basically the same restraining reaction.
  • Yet a further purpose of the present invention is to provide a supporting base which is effective in enabling the lever arm to be moved through a wide rotational arc of substantially 180°, so that the distance from a first selection tooth of the rack to a last selection tooth of the rack is maximized.
  • Yet another purpose of the present invention is to keep using a sheet-metal plate for cutting out a blank for the production of a lever-arm supporting base according to the present invention, which has substantially the same surface area as the sheet-metal plate used in view of cutting out a blank for the production of a conventional lever-arm supporting base provided with just two tabs.
  • a further, equally important purpose of the present invention is to provide a supporting base for the lever arm of a clamping device, in particular for a sports shoe, which is capable of being manufactured at competitive costs using generally and readily available tools and machinery.
  • a supporting base 10 for the lever arm of a clamping device in particular for a sports shoe, according to a preferred embodiment of the present invention comprises a plate 12 and at least three tabs, preferably four tabs 14, 20, 16, 18.
  • Such supporting base 10 for a lever arm may be manufactured by means of any viable sheet-metal forming process starting from a sheet-metal plate 100 under formation of scraps 102, such as for instance a continuous sheet-metal forming process of the progressive-die or similar kind.
  • Such sheet-metal forming process includes a mechanical cutting operation performed by using any suitable technology known in the art, such as for instance using a shearing machine, a laser cutting machine, a water-jet cutting machine, a plasma cutting machine, or the like, and a mechanical bending operation capable of being performed by using any suitable technology known in the art, as well, such as for instance using a bending machine, a punch-and-matrix forming machine, or the like.
  • Such mechanical cutting and bending operations may of course be carried out for forming the tabs 14, 20, 16, 18 and the plate 12 in any suitable order, either in a sequence or in parallel to each other.
  • the sheet-metal plate 100 is cut in so as to reproduce a contoured blank for the supporting base 10 of a lever arm.
  • Such blank has a contour that includes a cut-in profile for forming the plate 12, a first cut-in profile for forming a first tab 14, and a second cut-in profile for forming a second tab 20; in addition, such contour encloses at least one further cut-in profile for forming at least one respective further inner tab therewithin.
  • a polygonal surface may for instance be obtained, whose perimeter is formed by the cut-in profile for forming the plate 12, which may be in any suitable shape whatsoever, as joined to the first cut-in profile for forming the first tab 14 and the second cut-in profile for forming the second tab 20.
  • the first cut-in profile for forming the first tab 14 comprises a first through-bore 30, and the second cut-in profile for forming the second tab 20 comprises a second through-bore 36; moreover, such first and second cut-in profiles stretch out symmetrically relative to an axis X that lies longitudinally on the afore-noted polygonal surface.
  • the third inner cut-in profile for forming the third inner tab 16 includes a third through-bore 32, and the fourth inner cut-in profile for forming the fourth inner tab 18 includes a fourth through-bore 34; furthermore, such third and fourth cut-in profiles are symmetrical relative to the axis X.
  • the first, second, third and fourth cut-in profiles for forming the first, second, third and fourth tabs 14, 20, 16, 18, respectively are moreover arranged so that the first, second, third and fourth through-bores 30, 36, 32, 34 of the first, second, third and fourth tabs 14, 20, 16, 18, respectively, are aligned along an axis Y, which is substantially perpendicular to the axis X, and which lies on the afore-noted polygonal surface.
  • At least one attachment through-bore e.g. a first attachment through-bore 22 and a second attachment through-bore 24, may be formed on the afore-mentioned polygonal surface so as to enable the supporting base 10 for a lever arm to be secured on to a first flap of the sports shoe.
  • first tab 14 there may be formed the first tab 14, the second tab 20, the third inner tab 16, the fourth inner tab 18, as well as borders of the plate 12.
  • the first bending line 2, the second bending line 2', the third inner bending line 1 and the fourth inner bending line 1' are separated from each other and substantially parallel to the axis X; however, this is by no means a constraint to the purposes of the present invention.
  • the plate 12 itself may then be formed, the perimeter of which therefore includes the two first peripheral borders defined by the first bending line 2, the two second peripheral borders defined by the second bending line 2', the third inner peripheral border defined by the third inner bending line 1, the fourth inner peripheral border defined by the fourth inner bending line 1', two fifth inner peripheral borders defined by two respective portions of the third inner cut-in profile for forming the third inner tab 16, two sixth inner peripheral borders defined by two respective portions of the fourth inner cut-in profile for forming the fourth inner tab 18, as well as a seventh peripheral border defined by the cut-in profile for forming the plate 12.
  • Such perimeter confers the plate 12 a substantially rectangular shape featuring a first recess 50 and a second recess 52 provided along the axis Y and symmetrical to each other relative to the axis X.
  • the mechanical cutting and bending operations may be carried out in any suitable order whatsoever, i.e. either in a sequence or in parallel to each other, it may of course occur that the plate 12 is not completely formed at the end of the mechanical bending operation performed on the first, second, third and fourth cut-in profiles for forming the first, second, third and fourth tabs 14, 20, 16, 18, respectively, so that some mechanical operation is still needed for such plate to be completed.
  • the mechanical cutting operation for providing the first, second, third and fourth cut-in profiles for forming the first, second, third and fourth tabs 14, 20, 16, 18 with the respective first, second, third and fourth through-bores 30, 36, 32, 34, respectively is carried out on a shearing machine at the beginning of such continuous forming process.
  • the mechanical bending step of the process may further include a substep, in which there are formed a first bulging portion 30 in the first cut-in profile for forming the first tab 14 and a second bulging portion 40 in the second cut-in profile for forming the second tab 20.
  • the plate 12 may be formed so as to show a slight concavity replicating a surface of the first flap of a sports shoe, in view of allowing the supporting base 10 of the lever arm to be conveniently accommodated and securely attached onto the surface of the first flap of the sports shoe in a manner as largely known in the art, such as for instance through the insertion of usual fastening means, e.g. screws, rivets, or the like, in the first and second attachment through-bores 22, 24, as well as in corresponding bores in the first flap of the sports shoe.
  • fastening means e.g. screws, rivets, or the like
  • a surface area of the sheet-metal plate 100 used to work out the blank corresponding to the development of the supporting base for a lever arm according to the present invention is advantageously kept substantially identical to a surface area of the sheet-metal plate used to work out the blank corresponding to the development of a conventional supporting base for a lever arm provided with just two tabs, since additionally forming the third and fourth inner tabs is done by making use of material of said sheet-metal plate 100, which is contained within the afore-mentioned polygonal surface of the blank forming the supporting base.
  • first, second, third and fourth tabs 14, 20, 16, 18, which may have been formed in the afore-described manner, are arranged substantially perpendicular to the plate 12, which may have been formed in the afore-described manner, with the respective first, second, third and fourth through-bores 30, 36, 32, 34 positioned in a mutually coaxial arrangement.
  • first, second, third and fourth tabs 14, 20, 16, 18 are arranged substantially parallel to each other, since they project from the first, second, third and fourth bending lines 2, 2', 1, 1', respectively, which lie on the sheet-metal plate 100 in a substantially parallel arrangement to the axis X.
  • At least one bending line among the first, second, third and fourth bending lines 2, 2', 1, 1' may be slanting as compared with the other bending lines, so that at least one of the first, second, third and fourth tabs 14, 20, 16, 18 may as a result be slanting as compared with the other tabs.
  • the fourth inner tab 18, which protrudes from the fourth inner peripheral border of the plate 12 defined by the fourth inner bending line 1', and the second tab 20 adjacent thereto, which protrudes from the two second peripheral borders of the plate 12 defined by the second bending line 2', are facing each other with the respective fourth and second through-bores 34, 36 lying in a mutually coaxial arrangement.
  • such pair of tabs consisting of the fourth inner tab 18 and the second tab 20, may form a first fulcrum accommodation 82 capable of sustaining a first hinge-like linking member 88 (see Figure 7 ), such as a rivet, a screw or the like. More exactly, a first end portion of the first hinge-like linking member 88 is sustained by the fourth inner tab 18, whereas a second end portion of the first hinge-like linking member 88 is sustained by the second tab 20 to thereby form a kind of supported beam.
  • a first hinge-like linking member 88 see Figure 7
  • the first fulcrum accommodation 82 advantageously comprises the second recess 52.
  • This second recess 52 lies between the fourth inner tab 18 and the second tab 20 adjacent thereto, along the axis Y.
  • the third inner tab 16 which protrudes in the way of a corner from the inner peripheral border of the plate 12 delineated by the third inner bending line 1, and the first tab 14 adjacent thereto, which protrudes from the two first peripheral borders of the plate 12 defined by the first bending line 2, are facing each other with the respective third and first through-bores 32, 30 lying in a mutually coaxial arrangement.
  • such pair of tabs consisting of the third inner tab 16 and the first tab 14, may form a second fulcrum accommodation 80 capable of sustaining a second hinge-like linking member, such as a rivet, a screw or the like, to thereby form a kind of supported beam.
  • a second hinge-like linking member such as a rivet, a screw or the like
  • the second fulcrum accommodation advantageously comprises the first recess 50.
  • This first recess 50 lies between the third inner tab 16 and the first tab 14 adjacent thereto, along the axis Y.
  • first, second, third and fourth tabs 14, 20, 16, 18 can advantageously ensure a same constraint-related reaction, since each one of them protrudes from at least a respective peripheral border of the plate 12, thereby offering a constraint of the fixed joint type.
  • both the first hinge-like linking member and the second hinge-like linking member can rely on a stable and firm backing on which they rest at both end portions thereof, thereby turning out as being exposed to deformations to a markedly lesser extent.
  • the first through-bore 30 is provided open in a border 92 of the first tab 14 lying opposite to the plate 12
  • the second through-bore 36 is provided open in a border 98 of the second tab 20 lying opposite to the plate 12

  • the fourth through-bore 34 is provided open in a border 96 of the fourth inner tab 18 lying opposite to the plate 12.
  • first, second, third and fourth through-bores 30, 36, 32, 34 of the first, second, third and fourth tabs 14, 20, 16, 18, respectively, are provided in a closed configuration, as this is shown in Figures 3 and 4 .
  • any possible modified embodiments in which the at least one further inner cut-in profile for the formation of at least a further inner tab is formed within the contour of the development of the supporting base 10 for a lever arm according to any pattern or configuration whatsoever, has to be considered as falling within the scope of the present invention.
  • the third and fourth cut-in profiles for forming the third and fourth inner tabs 16, 18, respectively may be arranged inside the contour of the development of the supporting base 10 for a lever arm in a manner differing from the afore-described one.
  • the plate 12 may take a shape differing from the one that has been described and illustrated hereinbefore.
  • the plate 12 may take the shape of an outer rectangle (or other geometrical figure) with at least one inner aperture 120 provided inside said outer rectangle.
  • the perimeter of such inner aperture 120 may comprise two inner peripheral borders defined by two respective cut-in profiles extending substantially parallel to the axis Y, and two inner peripheral borders defined by two respective inner bending lines 1,1'.
  • the first and second tabs 14, 20 are formed from the first and second cut-in profiles (mechanical cutting operation) and the first and second bending lines 2, 2' (mechanical bending operation), respectively.
  • the first tab 14 protrudes from the peripheral border of the plate 12 (outer rectangle), which is defined by the first bending line 2
  • the second tab 20 protrudes from the peripheral border of the plate 12 (outer rectangle), which is defined by the second bending line 2'.
  • the third and fourth inner tabs 16, 18 are formed from the third and fourth cut-in profiles (mechanical cutting operation) and the third and fourth bending lines 1,1' (mechanical bending operation), respectively.
  • the third inner tab 16 protrudes from the inner peripheral border of the inner aperture 120, which is defined by the third inner bending line 1
  • the fourth tab 18 protrudes from the inner peripheral border of the inner aperture 120, which is defined by the fourth inner bending line 1'.
  • first, second, third and fourth bending lines 2, 2', 1, 1' are preferably separated from and substantially parallel to each other.
  • a clamping device in particular for a sports shoe, according to the present invention comprises the supporting base 10 for a lever arm, a lever arm 60, a connecting rod 72 and a pin 70.
  • the lever arm 60 comprises a grip end portion 87 and a first fulcrum appendix 64, a second fulcrum appendix 62, a first insertion through-bore 74 and a second, preferably blind bore 76.
  • the first and second fulcrum appendices 64, 62 are given a hooked shape, although this shall not be regarded as a limitation to the purposes of the present invention, and both of them are arranged in a position lying opposite to the grip end portion 87.
  • the connecting rod 72 is in turn provided with a through-bore 75 and a hook member arranged so as to be able to selectively engage a selection tooth of a rack attached on to a second flap of the sports shoe (not shown).
  • the coupling of the lever arm 60 with the related supporting base 10 is done by means of an articulated fulcrum joint.
  • This articulated fulcrum joint is formed by pivotally connecting the first fulcrum appendix 64 with the first fulcrum accommodation 82 and the second fulcrum appendix 62 with the second fulcrum accommodation 80.
  • This is practically done by inserting the first hinge-like linking member 88 in the second through-bore 36, the hooked portion of the first fulcrum appendix 64 and the fourth through-bore 34, and inserting the second hinge-like linking member in the first through-bore 30, the hooked portion of the second fulcrum appendix 62 and the third through-bore 32, respectively.
  • the lever arm 60 is hinged on to the supporting base 10 and, as a result, is able to pivot about a same (coaxial) axis of the first, second, third and fourth through-bores 30, 36, 32, 34, which shall be hereinafter referred to as the fulcrum axis.
  • lever arm 60 is pivotally coupled to the connecting rod 72 by inserting the pin 70 in the first insertion through-bore 74 of the lever arm, in the through-bore 75 of the connecting rod and in the second blind bore 76 of the lever arm.
  • the pin 70 is interchangeable and may not need being clinched by heading, hammering or the like.
  • the pin 70 is fixed to the lever arm 60 by having it screwed thereto, although any other suitable fixing solution may be used.
  • the pin 70 might in fact be knurled on its outer surface and be fixed to the lever arm 60 by force-fit kind of attachment.
  • the pin 70 does not extend fully through the lever arm 60, but remains rather locked in position inside the second blind bore 76 of the lever arm. Therefore, a side of the lever arm 60 comprising the second blind bore 76 may be formed to show a smaller thickness than a side of the lever arm 60 comprising the first insertion through-bore 74. Furthermore, the pin 70 may be solely visible from the side of the lever arm 60 that comprises the first insertion through-bore 74.
  • FIG. 7 Shown in Figure 7 is the clamping device in a closed condition thereof, so as to better illustrate some further advantages of the preferred embodiment of the present invention.
  • the articulated fulcrum joint comprises the supporting base 10, in which the first, second, third and fourth tabs 14, 20, 16, 18 are formed so as to have a reduced height as measured from the plate 12.
  • first, second, third and fourth tabs 14, 20, 16, 18, and namely from the borders thereof lying opposite to the plate 12 some material has been removed in order to open up the respective bores 30, 36, 32, 34, without however affecting the proper functionality of any of such bores.
  • first and second fulcrum appendices 64, 62 which are made in a crooked shape, orientate a first and a second open portion 86, 84 thereof in a direction facing away from the plate 12, so that they do not extend beyond the edges of the reduced-height first, second, third and fourth tabs 14, 20, 16, 18.
  • the clamping device when in the closed condition, the clamping device turns is rather low in its profile, extending very close to the surface of the sports shoe where it is attached to.
  • the second and first recesses 52, 50 allow the first and second appendices 64, 62, respectively, to move much closer to the first flap of the sports shoe than this would be possible in the case of a plate 12 that is on the contrary solid in the corresponding points. This may well be appreciated to be effective in further contributing to a low, flat profile of the clamping device in the closed condition.
  • Figure 8 shows the clamping device in a released condition so as to better illustrate the advantage deriving from the wide turning arc, substantially 180°, along which the lever arm can be rotated, since this practically allows to obtain a very large distance from a first selection tooth to a last selection tooth of the rack.
  • a supporting base 10 for the lever arm of a clamping device in particular for a sports shoe, which is effective in ensuring a greater fatigue strength and a greater resilience of the articulated fulcrum joint as compared to the teachings of the prior art, so that the number of utilization cycles of the clamping device is increased.
  • both the first fulcrum accommodation 82 and the second fulcrum accommodation 80 of the supporting base 10 for a lever arm are such as to ensure a same kind and extent of support to each of the end portions of the respective hinge-like linking member, since such fulcrum accommodations 82, 80 is formed by two respective tabs protruding from respective peripheral borders of the plate 12, thereby providing a respective constraint of the fixed joint type.
  • each tab of the first fulcrum accommodation 82 and each tab of the second fulcrum accommodation 80 are capable of ensuring the same constraint-related reaction, for instance through properly sizing the length of the peripheral edge wherefrom the tab protrudes.
  • the supporting base 10 for a lever arm allows the lever arm 60 to be rotated along a wide turning arc, substantially 180°, since the supporting base 10 is free of any obstacle along a trajectory of the lever arm 60.
  • the surface area of the sheet-metal plate 100 used to obtain a blank for forming the supporting base 10 for a lever arm is kept substantially unchanged as compared with the surface area of the sheet-metal plate used to obtain a blank for forming a conventional supporting base for a lever arm provided with just two tabs, so that there is no increase in the cost of the material involved for manufacturing the supporting base 10 for a lever arm according to the present invention.
