• VORWERK This patent describes crampons having a cylindrical shape associated with an inclined plane. US-3,577,633: this patent describes spikes in the shape of a pyramid.
• the main object of the invention is to provide spikes having a shape which prevents them from being aggressive in the event of an impact between players and which allows a good grip on all terrains.
• Another object of the invention is to provide a device comprising such cleats which is fixable on the sole of a football, rugby or similar shoe, so as to position the cleats in the best possible way avoiding the risk of injury by shock and allowing the best possible grip on the ground.
• Said first means located on the crampon consist of one or more studs and said second means, located on the sole or the plate consist of an imprint.
• the depth of the imprint corresponds to the thickness of the tongue so that only the crampon is outside the plane formed by the sole or by the plate.
• the imprint receives a closure element of complementary shape, so that the sole or the plate has a flat outer shape without a stud.
• the object of the invention is therefore a studded device which can be fixed on the sole of a football, rugby or similar shoe comprising at least one stud having an oblong shape defining an edge with a curvilinear profile in the direction of the largest dimension. of the crampon, and positioning means intended to position the crampon (s) according to a determined orientation relative to the axis of the sole.

• Figure 14 shows a bottom view of a shoe sole fitted with studs according to the invention.
• the crampons are crampons according to the embodiment without “step” and with “step” to clearly highlight the possible orientation of the studs and the use of studs of different shapes.
• simple studs without “step” are arranged substantially parallel to the outside side of the shoe, while the studs with “step” are arranged perpendicular to the longitudinal axis of the shoe.
• Figure 15 shows a top view of a shoe sole fitted with studs with "step” at the heel and without studs in the remaining part of the sole. This remaining part also highlights the pivot hole which is the blind hole 102 and the tapped holes 106 which allow the stud to be oriented.
• the front view shown in FIG. 1A shows the edge 12 with the convex curvilinear profile of the crampon in the direction of its largest dimension, this profile preferably being composed of two portions of convex curvilinear curves (circular, parabolic or other) joining with a slightly rounded point. This point or apex is necessary to facilitate penetration of the cleat in the ground.
• the spike 10 is narrower in the direction of its small dimension (orthogonal to the larger dimension) as illustrated in FIG. 1B showing a side view of the spike.
• the profile 14 has a rounded top edge.
• the stud has two studs 16 and 18 visible in the figures and in particular in Figure IC showing a bottom view of the stud.
• the pins 16 and 18 are intended to keep the crampon in a fixed position when the device according to the invention is fixed to the shoe.
• any shoe already equipped with tapped holes for placing studs is done as illustrated in Figure 2.
• the sole 20 seen in section has two threaded holes 22 and 24 for screwing two studs.
• a base 26 is fixed to the sole by two screws 28 and 30 which are screwed into the holes 22 and 24.
• the device according to the invention provided with two studs is fixed on the base 26 as follows.
• a support plate 32 preferably made of metal, has two locations at its ends and in alignment with the two tapped holes 22 and 24 of the sole (although this is not an obligation) on which two studs 34 and 36 are screwed by means of screws 38 and 40.
• the studs 34 and 36 have two tapped blind holes illustrated in dotted lines in FIG. 2.
• the support plate 32 could include three or more stud locations, or just one location.
• the plate 32 is in turn screwed onto the base 26 by means of the two screws 42 and 44 which are screwed into the tapped holes 46 and 48 of the base 26 passing through the holes 50 and 52 of the plate 32.
• the sole 20 has bosses where the cleats are placed as is often the case in football or rugby boots. These bosses provide sufficiently long screws despite the reduced thickness of the sole.
• Figure 2 illustrates the attachment of the device according to the invention on existing shoes, it is easy to provide suitable shoes for fixing the device. It suffices to provide for the fixing of the support plate 32 directly on the sole 20 by means of the screws 42 and 44 which are screwed into two tapped holes provided for this purpose. Of course, the base 26 is no longer necessary in this case.
• Figure 3 shows the support plate 32 seen from above with the holes 50 and 52 for the passage of the screws 42 and 44 and the holes 54 and 56 for fixing the studs on the plate. Notches are arranged radially around the fixing holes 54 and 56. When the crampon is positioned on the plate, the pins 16 and 18 penetrate into two opposite notches such as the notches 58 and 60 or 62 and 64 of the left crampon.
• the crampon is prevented from turning and taking a different position than that which it was desired to give to it during the fixing.
• the double pair of notches shown in Figure 3 allows positioning of the stud either with the curvilinear edge disposed longitudinally to the axis of the sole, or transversely.
• the tenon / notch mechanism can be replaced by any other equivalent mechanism allowing positioning of the stud. It is for example possible that it is the crampon which has notches while the tenons are found on the plate.
• the studs 10 which have just been described have the advantage of not being "aggressive" when they are positioned so that the curvilinear profile in the largest dimension of the stud (see FIG. 1A) is disposed longitudinally at the axis of the sole.
• their shape allows a gradual sinking into the ground, unlike the classic crampons which are rather cookie-cutter.
• the fact that they have a large lateral surface allows good attachment of the shoe and prevents frequent skidding with the usual crampons.
• the device according to the invention makes it possible to position the studs on the sole in the best way. This is what was achieved in the example illustrated in Figure 4 where six studs were attached to the sole 70. The two studs on the front 72 were positioned in the longitudinal direction. In this figure 4, the support plates 32 are shown.
• the risk of injury due to contact with the spikes of convex curvilinear shape is significantly reduced compared to the risk incurred with conventional tapered spikes.
• the rear studs 76 were positioned longitudinally for the same reason.
• the two intermediate studs 74 have been positioned transversely in order to exhibit a significant gripping force (due to their lateral surface), especially in the case of wet ground.
• a second embodiment of the invention consists in using studs whose shape is illustrated in FIGS. 5A, 5B and 5C.
• the spike 80 has a general shape corresponding to the shape of the spike 10 of Figures 1A, IB and IC, but it further comprises a "step" 82 whose profile 83 (fig. 5B) is curvilinear convex like profile 81 presented by the crampon in its largest dimension.
• profile 83 fig. 5B
• Such a crampon therefore has the advantage of not being aggressive when it is positioned transversely on the sole in the event of an impact between two players while allowing good grip on the ground.
• FIG. 6 An example of mounting this type of studs is illustrated in FIG. 6.
• the front studs 84, the rear studs 88 and also the intermediate studs 86 are positioned in the same way. This positioning is such that the step of each stud is placed forward in the longitudinal direction of the sole. Because of its convex curvilinear profile, the step of the crampon therefore poses no risk in the event of an impact.
• the studs being arranged transversely on the sole, they have a very high gripping force mainly on wet ground while s' sinking easily into the ground on dry ground.
• the cleat device according to the invention is fixed to the sole using a plate, it is possible to dispense with the plate as illustrated in FIGS. 7A, 7B and 8. Indeed, the crampon
• the 80 with its step 82 has a tongue 90 pierced with a countersunk hole 92 which makes it possible to fix the clamp using a screw screwed into a tapped hole 96 or 98 corresponding to the sole.
• the head of the screw is frustoconical to come to marry the milling of the hole 92.
• the crampon is positioned on the sole by means of a tenon 94 which is placed in a corresponding hole in the sole . The same positioning could also be obtained with a stud molded in the sole and a corresponding hole in the crampon.
• two tapped holes 96 and 98 can be provided in the sole.
• the tapped hole in the sole which is not used is closed by the crampon which prevents the earth from entering it.
• the crampon device according to the invention makes it possible to position the crampons differently during the game, depending on whether the ground which was dry at the start of the game then became wet with rain, or vice versa.
• studs 80 are not limiting. It is possible to operate this variant embodiment with any type of studs 10, 34, 36, 72, 74, 76, etc. In this embodiment well represented in FIG. 9, the sole has an imprint 100.
• This imprint 100 also includes a blind hole 102 and a tapped hole 106.
• the clamp 80 has a shape already shown in Figure 7B for example.
• This 80 has at its base an extension in the form of a tongue 90, in the rear part, and an extension under the form of a step 82, in the front part.
• This characteristic shape is in fact reproduced by the shape of the imprint 100.
• FIG. 10 represents the crampon 80 placed in an imprint 100, as described in FIG. 9. This positioning is well represented in FIG. 11.
• the sports shoe may need not be fitted with any studs.
• the imprints 100 can be eliminated by the installation of a closure element 108 which will be of form completely complementary to the shape of said imprint 100, whether or not it has a blind hole 102, and allowing also the installation of the screw 104. If there is a blind hole 102, the closure element 108 may be provided with a stud 110 cooperating with said hole 102.
• the sole of the sports shoe has ten footprints 100. Six of these footprints 100 are filled with studs 80, while the four footprints 100 remaining are filled by closure elements 108.
• Said first means are intended to be positioned on the existing football soles, using a plate at spacings corresponding to the fixing of the screwed studs of the shoes currently used.
• Said second means are fixed directly to the sole using a single screw and a pin forming a pivot.
• the proposed object of the invention has a sole in which recesses are formed, the depth of these imprints corresponds to the thickness of the tongue, so that only the spike of the chosen shape is outside the plane formed by the sole.
• Another originality of the invention resides in the filling of certain imprints with obturation elements of complementary shape so that at these locations the sole will have a flat outer shape, so the player can modify as desired the number of spikes. , for example depending on the nature of the soil.
• the specific shape of the crampon according to the invention and in particular the edge with a convex curvilinear profile makes it possible to obtain interesting results in particular in terms of kinematics.
• the convex curvilinear shape the width not being limiting, the penetration into the ground is always greater than that of the current tapered crampons, while the convex curvilinear "step" of the crampon facilitates the escape.
• the studs according to the invention allow all possible combinations in terms of the choice of studs according to the invention with or without step, or their orientation relative to the longitudinal axis.
• the frustoconical shapes with circular pyramidal section act like a cookie cutter: these shapes cut the lawn or even push it of its diameter into the ground.
