    Detailed description of the invention
    First the method for producing an anti-skid stud comprising a supporting part 1 and a stud 25 pin 2 that is partly arranged in a blind hole 3 in the supporting part 1 and some variants and embodiments of the method will be described in greater detail.
    The method comprises providing a supporting part 1 that is made of elastic or of elastically deformable material such as of polymer and that has a blind hole 3.
    The method comprises providing a stud pin 2 having a proximal end 4 and a distal end 5. 30 The stud pin 2 can be made of or comprise hard material such as metal, and comprises preferably, but not necessarily, hard metal such as tungsten carbide and/or other carbides.
    The stud pin 2 that is provided comprises a protruding grip section 6 and an insertion section 7 having at least one first holding section 16. In the embodiments illustrated in figures 1 to 40 and in figures 45 to 52, the insertion section 7 of the stud pin 2 has one first holding section 16 35 and in the eleventh embodiment illustrated in figures 41 to 44, the insertion section 7 of the stud pin 2 has two first holding sections 16.
    The blind hole 3 of the supporting part 1 that is provided has a bottom 15 and a second holding section 17. The second holding section 17 has a smallest cross-section A that is smaller
    20185176 PRH 26 -02- 2018 than a largest cross section B of the first holding section 16 of the insertion section 7 of the stud pin 2 that is provided.
    The method comprises providing at least one of i) the insertion section 7 of the stud pin 2 with a first tapering section 9 that tapers for example in a beveled and/or rounded manner toward 5 the distal end 5 of the stud pin 2, and ii) a mouth 18 of the blind hole 3 of the supporting part 1 with a beveled and/or rounded edge. In the embodiment illustrated in figures 1 to 4, a first tapering section 9 is provided, but the mouth 18 of the blind hole 3 is not provided with a beveled and/or rounded edge. In the embodiment illustrated in figures 13 to 18, no first tapering section is provided, but the mouth 18 of the blind hole 3 is provided with a beveled edge 3. In the other 10 embodiments, a first tapering section 9 is provided, and the mouth 18 of the blind hole 3 is provided with a beveled and/or rounded edge
    The method comprises pressing the insertion section 7 of the stud pin 2 into the blind hole 3 of the supporting part 1 with the distal end 5 of the stud pin 2 leading the insertion section 7 of the stud pin 2 so that said largest cross section B of the first holding section 16 of the stud pin 2 at 15 least partly passes said smallest cross-section A of the second holding section 17 of the blind hole 3 of the supporting part 1. Because the supporting part 1 is made of elastic or elastically deformable material, the largest cross section B of the first holding section 16 of the stud pin 2 can at least partly pass the smallest cross-section A of the second holding section 17 of the blind hole 3 of the supporting part 1.
    A purpose of the first holding section 16 of the stud pin 2 and of the second holding section of the blind hole 3 of the supporting part 1 to retain the stud pin 2 in the blind hole 3 of the supporting part 1.
    A purpose of the first tapering section 9 of the insertion section 7 of the stud pin 2 and/or of the beveled or rounded edge of the mouth 18 of the blind hole 3 of the supporting part 1 is to 25 enable pressing of the stud pin 2 into the blind hole 3 of the supporting part 1.
    The insertion section 7 of the stud pin 2 can be provided with a first holding section 16 in the form of a first enlargement (nor marked with a reference numeral), as is the case in the embodiments shown in the figures and the blind hole 3 of the supporting part 1 can be provided with a second holding section 17 in the form of a second enlargement (nor marked with a reference 30 numeral), as is the case in the first to ninth embodiment illustrated in figures 1 to 36 and in the thirteenth embodiment illustrated in figures 49 to 52. In such cases, pressing of the insertion section 7 of the stud pin 2 into the blind hole 2 of the supporting part 1 causes the largest cross section B of the first holding section 16 of the stud pin 2 to pass the smallest cross-section A of the second holding section 17 of the blind hole 3 of the supporting part 1.
    Alternatively, the insertion section 7 of the stud pin 2 can be provided with a first holding section 16 in the form of a first enlargement (nor marked with a reference numeral), as is the case in the embodiments shown in the figures and the cross-section of the blind hole 3 of the supporting part 1 can be essentially the same throughout the blind hole 3 of the supporting part 1, as is the
    20185176 PRH 26 -02- 2018 case in the tenth to twelfth embodiment illustrated in figures 37 to 48. In such cases, pressing of the insertion section 7 of the stud pin 2 into the blind hole 2 of the supporting part 1 causes the largest cross section B of the first holding section 16 of the stud pin 2 to only partly pass the smallest cross-section A of the second holding section 17 of the blind hole 3 of the supporting part 5 1. Because the supporting part 1 is made of elastic or elastically deformable material, the first holding section 16 of the insertion section 7 of the stud pin 2 will cause an enlargement in the blind hole 3 of the supporting part 1.
    The first holding section 16 of the insertion section 7 of the stud pin 2 that is provided can have a second tapering section 8 that tapers towards the proximal end 4 of the stud pin 2, as is the 10 case in the embodiments illustrated in figures 1 to 32 and in figures 45 to 52.
    Alternatively, the insertion section 7 of the stud pin 2 that is provided can between the first holding section 16 and the protruding grip section 6 comprise a top section 12, which cross section is essentially the same throughout the top section as illustrated in the embodiments illustrated in figures 33 to 40.
    The form and the dimensions of at least a part of the blind hole 3 of the supporting part 1 that is provided corresponds preferably, but not necessarily, essentially to the form and to the dimensions of at least a part of the insertion section 7 of the stud pin 2. This provides for a tight fit between the insertion section 7 of the stud pin 2 and the blind hole 3 of the supporting part 1, which extends the service-life of the anti-skid stud, because the stud pin 2 is well-retained in the 20 supporting part 1.
    The method can comprise pressing the insertion section 7 of the stud pin 2 into the blind hole 3 of the supporting part 1 with the distal end 5 leading the stud pin 2 until the distal end 5 of the stud pin 2 abuts the bottom 15 of the blind hole 3 and until the protruding grip section 6 of the stud pin 2 is located outside the blind hole 3, as in the embodiments illustrated in figures 1 to 48. 25 An advantage of this is that the stud pin 2 is then prevented from sinking deeper into the blind hole 3 of the supporting part 1.
    Alternatively, the method can comprise pressing the insertion section 7 of the stud pin 2 into the blind hole 3 of the supporting part 1 with the distal end 5 leading the stud pin 2 until the distal end 5 of the stud pin 2 is at a distance from the bottom 15 of the blind hole 3 and until the 30 protruding grip section 6 of the stud pin 2 is located outside the blind hole 3, as in the thirteenth embodiment illustrated in figures 49 to 52. In such case the first holding section 16 of the insertion section 7 of the stud pin 2 can together with the second holding section 17 of the blind hole 3 of the supporting part 1 be configured to prevent the stud pin 2 from sinking deeper into the blind hole 3 of the supporting part 1. An advantage of this embodiment is that the length of the stud pin 35 2 has then a smaller impact on the length of the protruding grip section 6 of the stud pin 2.
    In the method, the second section 9 of the insertion section 7 can extend directly from the distal end 5 in the stud pin 2 that is provided, as in the embodiments shown in figures 1 to 48.
    In the method, the stud pin 2 that is provided can comprise a leading section 10 between
    20185176 PRH 26 -02- 2018 the first tapering section 9 of the first holding section 16 of the insertion section 7 of the stud pin 2 and the distal end 5 of the stud pin 2, provided that the stud pin 2 is provided with such first tapering section 9, as in the thirteenth embodiment shown in figures 49 to 52.
    In the method, the stud pin 2 that is provided can comprise a middle section 11 between 5 the first tapering section 9 of the first holding section 16 of the insertion section 7 and the second tapering section 8 of the first holding section 16 of the insertion section 7, provided that the stud pin 2 comprises such first tapering section 9 and such second tapering section 8, as in the eight embodiment shown in figures 29 to 32.
    In the method, the stud pin 2 that is provided can comprise a top section 12 between the 10 second tapering section 8 of the insertion section 7 and the protruding grip section 6, provided that the stud pin 2 comprises such second tapering section 8, as in the seventh embodiment shown in figured 25 to 28.
    In the method, the second tapering section 8 of the insertion section 7 can extend directly from the protruding grip section 6 of the stud pin 2 that is provided, provided that the stud pin 2 15 comprises such second tapering section 8, as in the embodiments shown in figures 1 to 24,.
    The optional second tapering section 8 of the first holding section 16 of the insertion section 7 of the stud pin 2 can be in the form of a first truncated cone, and the optional first tapering section 9 of the first holding section 16 of the insertion section 7 of the stud pin 2 can be in the form of a second truncated cone.
    The insertion section 7 of the stud pin 2 that is provided can have a form enabling inserting the stud pin 2 only in one position into the blind hole 3 of the supporting part 1.
    The method can comprise providing the second holding section 17 of the blind hole 3 of the supporting part 1 with an undercut recess (not marked with a reference numeral), wherein the first holding section 16 of the insertion section 7 of the stud pin 2 is configured to latch into the 25 undercut recess of the second holding section 17 of the blind hole 3 of the supporting part 1 when pressing the insertion section 7 of the stud pin 2 into the blind hole 3 of the supporting part 1. An advantage of this is that is then easy to press the stud pin 2 into a correct position blind hole 3 in the supporting part 1.
    The method can comprise providing the supporting part 1 with a top flange 13 and with a 30 bottom flange 14. This enhances keeping of the anti-skid stud in a tire, when the anti-skid stud is mounted in a recess in a tire.
    The supporting body can comprise a ridge or a tooth or a spline on the outer surface of the supporting body. Additionally or alternatively, the supporting part 1 can have an outer form diverging from the form of a solid of revolution An advantage of this is that the anti-skid stud is 35 prevented from rotating a recess of the tire when mounted in a recess in a tire and the anti-skid stud is kept in a predetermined rotational position with respect to the tire. This also allows to insert the anti-skid stud into a recess in a tire with a machine in a predetermined position and promotes also retaining of the anti-skid stud in a tire.
    20185176 PRH 26 -02- 2018
    The method can comprise heating at least one of the supporting part 1 and the stud pin 2 prior pressing the insertion section 7 of the stud pin 2 into the blind hole 3 of the supporting part
    1. An advantage of this is that it is then easier to press the stud pin 2 into the blind hole 3, because the supporting part 1 softens and can better yield during the pressing.
    Next the anti-skid stud comprising a supporting part 1 and a stud pin 2 that is partly arranged in a blind hole 3 in the supporting part 1 and some variants and embodiments of the antiskid stud will be described in greater detail.
    The anti-skid stud comprises a supporting part 1 that is made of elastic or of elastically deformable material such as of polymer and that has a blind hole 3, and a stud pin 2 having a 10 proximal end 4 and a distal end 5. The stud pin 2 can be made of or comprise hard material such as metal, and comprises preferably, but not necessarily, hard metal such as tungsten carbide and/or other carbides.
    The stud pin 2 comprises a protruding grip section 6 and an insertion section 7 having at least one first holding section 16. In the embodiments illustrated in figures 1 to 40 and in figures 15 45 to 52, the insertion section 7 of the stud pin 2 has one first holding section 16 and in the eleventh embodiment illustrated in figures 41 to 44, the insertion section 7 of the stud pin 2 has two first holding sections 16.
    The blind hole 3 of the supporting part 1 has a bottom 15 and a second holding section 17 having a smallest cross-section A that is smaller than a largest cross section B of the first holding 20 section 16 of the insertion section 7 of the stud pin 2.
    At least one of the insertion section 7 of the stud pin 2 is provided with a first tapering section 9 that tapers for example in a beveled and/or rounded manner toward the distal end 5 of the stud pin 2 and a mouth 18 of the blind hole 3 of the supporting part 1 is provided with a beveled and/or rounded edge. In the embodiment illustrated in figures 1 to 4, a first tapering section 9 is 25 provided, but the mouth 18 of the blind hole 3 is not provided with a beveled and/or rounded edge.
    In the embodiment illustrated in figures 13 to 18, no first tapering section is provided, but the mouth 18 of the blind hole 3 is provided with a beveled edge 3. In the other embodiments, a first tapering section 9 is provided, and the mouth 18 of the blind hole 3 is provided with a beveled and/or rounded edge
    Said insertion section 7 of the stud pin 2 is retained in the blind hole 3 of the supporting part 1 by a form-fit and/or press-fit connection between the insertion section 7 of the stud pin 2 and the blind hole 3 of the supporting part 1. A form-fit and press-fit connection is achieved by providing the blind hole 3 of the supporting part 1 and the insertion section 7 of the stud pin 2 with an at least partly matching design and by making the dimensions of the blind hole 3 of the 35 supporting part 1 smaller than the dimensions of the insertion section 16 of the stud pin.
    Said largest cross section B of the first holding section 16 of the insertion section 7 of the stud pin 2 is arranged between the bottom 15 of the blind hole 3 of the supporting part 1 and said smallest cross-section A of the second holding section 17 of the blind hole 3 of the supporting part
    20185176 PRH 26 -02- 2018
    1.
    A purpose of the first holding section 16 of the stud pin 2 and of the second holding section 17 of the blind hole 3 of the supporting part 1 to retain the stud pin 2 in the blind hole 3 of the supporting part 1.
    A purpose of the first section 9 of the insertion section 7 of the stud pin 2 or of the beveled or rounded edge of the mouth 18 of the blind hole 3 of the supporting part 1 is to enable pressing of the stud pin 2 into the blind hole 3 of the supporting part 1, when manufacturing the anti-skid stud.
    The insertion section 7 of the stud pin 2 can be provided with a first holding section 16 in 10 the form of a first enlargement (nor marked with a reference numeral), as is the case in the embodiments shown in the figures and the blind hole 3 of the supporting part 1 can be provided with a second holding section 17 in the form of a second enlargement (nor marked with a reference numeral), as is the case in the first to ninth embodiment illustrated in figures 1 to 36 and in the thirteenth embodiment illustrated in figures 49 to 52. In such cases, the largest cross section B of 15 the first holding section 16 of the stud pin 2 is between the smallest cross-section A of the second holding section 17 of the blind hole 3 of the supporting part 1 and the bottom 15 of the blind hole 3 of the supporting part 1 in the anti-skid stud.
    Alternatively, the insertion section 7 of the stud pin 2 can be provided with a first holding section 16 in the form of a first enlargement (nor marked with a reference numeral), as is the case 20 in the embodiments shown in the figures and the cross-section of the blind hole 3 of the supporting part 1 can be essentially the same throughout the blind hole 3 of the supporting part 1, as is the case in the tenth to twelfth embodiment illustrated in figures 37 to 48. In such cases, the largest cross section B of the first holding section 16 of the stud pin 2 can be considered to be at the smallest cross-section A of the second holding section 17 of the blind hole 3 of the supporting part 25 1. Because the supporting part 1 is made of elastic or elastically deformable material, the first holding section 16 of the insertion section 7 of the stud pin 2 will however cause an enlargement in the blind hole 3 of the supporting part 1.
    The first holding section 16 of the insertion section 7 of the stud pin 2 can have a second tapering section 8 that tapers towards the proximal end 4 of the stud pin 2, as in the embodiments 30 illustrated in figures 1 to 32 and in figures 45 to 52.
    Alternatively, the insertion section 7 of the stud pin 2 can between the first holding section 16 and the protruding grip section 6 comprise a top section 12, which cross section is essentially the same throughout the top section as illustrated in the embodiments illustrated in figures 33 to 4O.The form and the dimensions of at least a part of the blind hole 3 of the supporting part 1 35 corresponding preferably, but not necessarily, essentially to the form and to the dimensions of at least a part of the insertion section 7 of the stud pin 2.
    The distal end 5 of the stud pin 2 can abut the bottom 15 of the blind hole 3 of the supporting part 1 so that the protruding grip section 6 of the stud pin 2 is located outside the blind hole 3 of
    20185176 PRH 26 -02- 2018 the supporting part 1, as in the embodiments illustrated in figures 1 to 48.
    Alternatively, the distal end 5 of the stud pin 2 can be located at a distance from the bottom 15 of the blind hole 3 of the supporting part 1 so that the protruding grip section 6 of the stud pin 2 is located outside the blind hole 3 of the supporting part 1, as in the embodiment illustrated in 5 figures 49 to 52.
    The stud pin 2 can comprise a leading section 10 between the first tapering section 9 of the first holding section 16 of the insertion section 7 of the stud pin 2 and the distal end 5 of the stud pin 2, provided that the stud pin 2 is provided with such first tapering section 9, as in the thirteenth embodiment shown in figures 49 to 52.
    The stud pin 2 can comprise a middle section 11 between the first tapering section 9 of the first holding section 16 of the insertion section 7 and the second tapering section 8 of the first holding section 16 of the insertion section 7, provided that the stud pin 2 comprises such first tapering section 9 and such second tapering section 8, as in the eight embodiment shown in figures 29 to 32.
    The stud pin 2 can comprise a top section 12 between the second tapering section 8 of the insertion section 7 and the protruding grip section 6, provided that the stud pin 2 comprises such second tapering section 8, as in the seventh embodiment shown in figured 25 to 28.
    The second tapering section 8 of the insertion section 7 can extend directly from the protruding grip section 6 of the stud pin 2 that is provided, provided that the stud pin 2 comprises 20 such second tapering section 8, as in the embodiments shown in figures 1 to 24 and 29 to 32 and 45 to 52.
    The optional second tapering section 8 of the first holding section 16 of the insertion section 7 of the stud pin 2 can be in the form of a first truncated cone, and the optional first tapering section 9 of the first holding section 16 of the insertion section 7 of the stud pin 2 can be in the form of a 25 second truncated cone.
    The insertion section 7 of the stud pin 2 can have a form diverging from the form of a solid of revolution, and the protruding grip section 6 of the stud pin 2 can have a form diverging from the form of a solid of revolution. An advantage of this is that the stud pin 2 is prevented from rotating in the blind hole 3 and the stud pin 2 is kept in a predetermined rotational position with 30 respect to the blind hole 3.
    Alternatively, the insertion section 7 of the stud pin 2 can have the form of a solid of revolution, and the protruding grip section 6 of the stud pin 2 can have the form of a solid of revolution.
    The blind hole 3 of the supporting part 1 can be provided with an undercut recess, and the 35 first holding section 16 of the insertion section 7 of the stud pin 2 can be latched into the undercut recess in the blind hole 3 of the supporting part 1. An advantage of this is that is then easy to press the stud pin 2 into a correct position blind hole 3 in the supporting part 1.
    The supporting part 1 can be provided with a top flange 13 and with a bottom flange 14.
    This enhances keeping of the anti-skid stud in a tire, then the anti-skid stud is mounted in a recess in a tire.
    The supporting body can comprise a ridge or a tooth or a spline on the outer surface of the supporting body. Additionally or alternatively, the supporting part 1 can have an outer form 5 diverging from the form of a solid of revolution An advantage of this is that the anti-skid stud is prevented from rotating a recess of the tire when mounted in a recess in a tire and the anti-skid stud is kept in a predetermined rotational position with respect to the tire.
    It is apparent to a person skilled in the art that as technology advanced, the basic idea of the invention can be implemented in various ways. The invention and its embodiments are 10 therefore not restricted to the above examples, but they may vary within the scope of the claims.
