Description

The present invention relates to crampons for shoes, in particular

  those used in sports such as rugby and football, in which

  physical contact may occur.

  Sports shoes, for example worn by rugby players, have crampons so that the player can have a good support on the ground on which the game

  As the terrain can be soft, the crampons must

  long enough to allow such a hanging. For this reason, the spikes were made of hard material rather than soft material. Indeed, if the crampons are formed of a soft material such as rubber for example, a player who has them and who

  playing on hard ground tends to present an insta-

  because crampons have a "tipping" effect.

  When using long crampons of hard material on a hard ground that can be not only the ground but also the passage leading from a cloakroom to the field,

  they can wear to the point of presenting tapered edges.

  For example, during a game, if sharp edges of the cleats of a player's shoe come into contact with another player, that player may suffer cuts that

  can have a serious character.

  The invention relates to an improved crampon

for shoes.

  More specifically, the invention relates to a cremation

  footwear comprising: (i) a body of a hard synthetic material, (ii) a device placed at a first

  end of the body and intended for the easy fixing of the crem-

  pon on the shoe and its easy removal and (iii) a

  protective coating of a material that does not practically

  no cut and which has a color different from that of the body, this protective coating being fixed to the

  end face of the body that is furthest away from the

  positive fixation and at least on the part of the wall

  side of the body that is contiguous to the end surface.

  The hard material may be a thermoplastic

  This may be, for example, "nylon" or, alternatively, "nylon" reinforced with fibrous material. The device for attaching the crampon to the shoe placed at a first end of the body may protrude therefrom and may be formed by a narrowed and threaded extension of the body. Alternatively, this device may

  be a bolt or similar member, preferably metal-

  In another variant, the fastening device may be a bolt or the like, with a head around which at least the body is molded.

  also preferably formed of metal, which can be introduced

  in a central bolt housing hole formed in the body, a suitably shaped seat being formed

  at one end of the hole housing the head of this body.

  When the head does not completely occupy the seat, the rest of it can be occupied by the material which causes practically no cut and which facilitates the jamming of the material on the body and avoids the exposure

  of the head when the coating wears out.

  The material which causes practically no cutting may be rubber or a similar material, for example

  nitrile rubber, preferably of the carbon type,

Xyle.

  The part of the body that is adjacent to the extr-

  which has the device for fixing the crampon on the boot may have a configuration such that it can easily be turned, for example by a suitable key,

  to be inserted by screwing into a suitable hole

  tapped into the shoe.

  A crampon according to the invention has the advantages

  following stages: (a) as the body is made of a hard material,

  it may have a length that is suitable both for

soft rain and hard ground,

  (b) as the lower part of at least the cram-

  pon is covered with a material causing virtually no cut, the crampon has very little risk of

  cutting of the body or other injuries to persons

  worn by the crampon, during use and after wear,

  (c) when the matter which does not cause

  In fact, no cut has been used up to the body, this phenomenon

  nomene appears clearly by accidental inspection of

  pon (eg by a referee looking at the crampons before the start of the match and at half-time) as the body of different color is exposed, a worn crampon can then be easily changed and replaced by a new one in

these circumstances.

  Other features and advantages of the

  will be better understood by reading the description

  which will follow examples of embodiment and with reference to the attached drawings in which:

  pon according to a first embodiment of the invention; Figure II of Figure 1; the figure of a complete crampon of the invention; the figure of Figure 3; the figure of a complete crampon the invention; Figure VI of Figure 5; the figure of a complete crampon of the invention; Figure VIII of Figure 7; the figure of a complete crampon of the invention; and 2 is an elevation along the arrow 3 is in a partial sectional elevation the first embodiment 4 is a section along the line IV-IV is in a partial sectional elevation a second embodiment of 6 is an elevation according to the arrow 7 is in a partial sectional elevation a third embodiment 8 is an elevation along the arrow 9 is in a partial sectional elevation a fourth embodiment Figure 10 is an elevation along the arrow

X of Figure 9.

  As shown in Figures 1 to 4, the body

  1 of a crampon according to a first embodiment of the invention.

  vention is made of "Nylon" reinforced with fiberglass, this

  material being thermoplastic so that the body is

  by a suitable molding process In this mode of

  realization, the armed matter is of red color.

  The body has a hole 2 whose lower part

  opens into a seat 3 of square section The upper part

  the hole opens into a circular cavity 4 having a ring of protruding projections 5 which are intended

  to tighten the underside of the sports shoe to-

  which the crampon has to be fixed As shown, the body

  has a flange 6 at its upper end, and an ad-

  7 of hexagonal section, forming a shoulder 8

  at the connection of a lower part 9 of frustoconical shape.

  A device for easy attachment of the crampon on

  the shoe, also allowing easy removal of

  pon, includes a galvanized mild steel bolt 10

  goes up into hole 2 and has a head 11 of square section,

  intended 3 to cooperate with the seat 3.

  A cap 12 having the shape of a thimble

  and formed of carboxylated nitrile rubber, forming a

  protective clothing of the body 1 and intended to cooperate with the ground, is advantageously formed and bonded to the lower end 9 of the body, the upper edge of the cap being in contact with the shoulder 8 Thus, the cap is fixed to the face of the 13 end of the body and the portion 14 of the side wall of the body which is contiguous to this end wall The nitrile rubber is not likely to cause virtually cuts so that, if it hit the skin of 'a player for example during a game of rugby or football, this player is not likely to be hurt by cut, even when the coating is

  This material is also glued to the end face 15

  The small outer part of the seat 3 which is not occupied by the head It contains the

  nitrile rubber as shown in Figure 3.

  During the manufacture of the crampon, the mold

  12 of the cap 12 and its bonding on the body 1 and the bolt 10 are made simultaneously in a suitable mold.

  in which the body and bolt are placed in

  appears. The crampon is screwed into a suitable receiving device (not shown) for example a tapped insert attached to the underside of the sports shoe and is also removed by using a suitable key,

placed on the hexagonal part 7.

  The color of the finished crampon cap is

  so that, after prolonged use of the crem-

  the relatively soft nitrile rubber of the cap wears out to the hard material of the "Nylon" armed with the body 1, this material which is red being very visible in contrast with the dark matter of the cap. This phenomenon indicates that

  the crampon must be replaced immediately.

  As indicated in Figures 5 and 6, the body 21 of the crampon of the second embodiment of the invention is also formed of "nylon" -armed fiberglass and red color As in the first embodiment, the body has a hole 22 whose lower end opens

  in a seat 23 of square section and whose extreme end

  the outer edge opens into a circular cavity 24 having a

  circle of protrusions 25 protruding upwards.

  The body 21 comprises, at its upper end 26, a flange 27 which differs from that of the first embodiment in that it comprises two parallel plates 28,

  The central part of the body also has a general shape.

  truncated cone and a shoulder 31 at the end connection.

  lower mite 32 which also has a frustoconical shape A bolt 33 having a head 34 of square section which cooperates

  with the seat 23, forms the device for fixing the crem-

pon on a shoe.

  A cap 35 having substantially the configuration

  of a dome and made of carboxylated nitrile rubber,

  the protective coating black to be in contact with the body 21 and having the shape of a thimble, is adhered to the lower portion 32 of the body, the upper edge 36 of the cap being disposed against the shoulder 31 Thus, the cap is attached to the lower face 37 of the body and to the portion 38 of the side wall of the body which is contiguous to this end face. The nitrile rubber is also bonded to the end face 39 of the head 34 The small part external seat 23 which is not occupied

  by the head 34 contains nitrile rubber.

  The crampon is manufactured as described for the first embodiment, and it is put in place on the

  shoe and removed from it by means of a suitable wrench.

  nable applied on the two parallel plates 28, 29.

  As in the first embodiment, when the cap 35 is worn up to the body 21, the red-armed "Nylon" of this body is clearly visible

  and indicates that the crampon needs to be replaced.

  Reference is now made to Figures 7 and 8 which

  represent a crampon according to a third embodiment of

  4 having a red body 41 and a black cap 42 formed from the materials already indicated for the first and second embodiments, this spike having no flange at the upper part 43 of the body which has a constant diameter upwards and is connected to the central portion 44 of frustoconical shape This central portion has a shoulder 45 to the connection of its lower portion 46 which also has a frustoconical shape As in the second embodiment, the cap 42 has a substantially domed configuration and it is properly glued to the body 41, its

  upper edge 47 being in contact with the shoulder 45

  upper tremité 43 which has no flange has two parallel plates 48, 49 on which a suitable key can be arranged when mounting the crampon on a shoe or

during his abduction.

  In the fourth embodiment shown in FIGS. 9 and 10, the crampon still has a red body 51 and a black cap 52 formed of the indicated materials.

  for the previous embodiments, the upper part

  The face 58 of the cap 52 which is turned towards the ground is substantially flat. In addition, the seat 59 of square section formed in the body for the housing of the body is provided with a flange and four flats 54, 55, 56, 57. head 60 of the bolt 61 is significantly deeper than in the other embodiments so that a larger amount

  carboxylated nitrile rubber of the cap may be

  feels in the body and can ensure a better bonding of the cap on the body because this collage is made on a larger surface This better bonding gives the cap

  better resistance to forces exerted laterally.

  The housing hole 62 of the bolt 61 comprises, at

  its upper end, three protrusions 63 of triangular profile

  radially inwardly and which are intended to tighten the bolt, this characteristic being

  particularly advantageous when the bolt is initially

  placed in hole 62 and when the hood

  is then glued to the body and the head 64 of the bolt.

  The arrangement of the plates 54 to 57 and the curved parts 65, 66, 67, 68 placed between them avoids that

  edges and thus dangerous are presented by the

tie 53.

  Although, in the embodiments described above with reference to the drawings, the body of all the crampons is formed of "nylon" reinforced with a fibrous material, in other embodiments of the invention, the body

  may be made of unarmed nylon or any other

  a suitable synthetic material having the required hardness and which may if necessary be equipped with a fibrous material such as

  that for example glass fibers.

  Furthermore, although in the embodiments described above in the drawings, the cap is formed of carboxylated nitrile rubber, the invention is not limited to this material because the cap may be formed of any

  other suitable material which does not cause

  tically and of synthetic or natural type.

  In addition, although the embodiments described above with reference to the figures relates to a device for fixing the spikes on the shoe as comprising a bolt having a square section head, in other embodiments, the bolt may have a head any other section'convenable or may include a threaded member of which a portion is knurled or has suitable projections for blocking the organ

on the body of the crampon.

  Of course, various modifications can be made by those skilled in the art to the devices which have just been described as examples only.

  limiting without departing from the scope of the invention.
