OBJECT OF THE INVENTION
[0001] The present specification relates to an application for a patent of invention concerning a new arrangement for regulating multidirectional movements of the studs incorporated in sports footwear, particularly sports footwear used in football, rugby, etc., the obvious purpose of which is to place the studs themselves in suitable points of the sole of the footwear in such a way that as a result thereof an adaptation of same is achieved to the characteristics of the sportsman and to the conditions of the ground where the competition takes place.
FIELD OF THE INVENTION
[0002] This invention is applicable within the industry devoted to the manufacturing of sports footwear.
BACKGROUND OF THE INVENTION
[0003] As far as the applicant knows, nowadays there is different types of footwear, generally used to practice specific sports, such as football or rugby competitions, etc., that inexcusably require the use of footwear provided with studs.
[0004] Those studs are located on the sole of the footwear according to a general location criterion, and particularly in very special cases they are located in a specific way in accordance with the physical features of the sportsman himself.
[0005] In order to fix these studs, reinforcing areas have been provided on the underside of the sole, in which they are driven, screwed or adjusted, and once the studs have been located and fixed, they cannot be mobilized in a simplified manner.
[0006] The steps for locating the studs in a specific way require the use of the services of a specialist.
[0007] The obvious solution for the present existing problem would be that the studs were able to be located unidirectionally or multidirectionally without requiring the intervention of a specialist, and at the same time they could be mobilized in accordancde with the features of the ground where the competition takes place or according to specific conditions of the player.
[0008] However, so far we are not aware of the existence of an invention provided with the features which have been pointed out as suitable.
DESCRIPTION OF THE INVENTION
[0009] The new arrangement for regulating multidirectional movements of the studs incorporated in sports footwear as proposed by the invention constitutes an obvious innovation in itself within their application field, since the use of this new arrangement will allow the users of this type of footwear to be able to locate the studs of their footwear in a proper form consistent with their needs or particularities, both multidirectionally and unidirectionally.
[0010] More specifically, the new arrangement for regulating multidirectional movements of the studs incorporated in sports footwear which is the subject matter of the invention consists in using a female part having a quadrangular shape, as seen in a plan view, made of a metallic material, which is provided in the central area of one of its major faces with an internally hollow emergent projection in the manner of a hollow cylinder.
[0011] Such female part will emerge from the lower side of the footwear, and once the same is held in a circular part, as seen in a plan view, provided with a central quadrangular opening, it will allow a stud provided with a threaded or non-threaded cylindrical protuberance to be set in place, whereby - on account of the mobilization caused by the body of the female part in the central opening of the holding part - it is made possible for the located studs to be positioned at a proper angularity consistent with the desired features, spaced apart in a greater or smaller extent or as considered convenient in accordance with the created possibilities due to the central opening of the holding part that enables a multidirectional mobility of the studs.
[0012] The invention also allows the female part itself to be located on the sole and, with the aid of two complementary side parts, to regulate the forward or backward movements of the stud itself, which will emerge from the underside of the footwear and will be assisted in locating and fixing it by means of the holding part which, in both cases provided with an emergent bolt and an upper surface substantially broader than the area of adaptation to the ground, vill prevent the mobility of the stud once the same has been adjusted on fixing it to the surface of the sole.
[0013] Apart from the fact that the footwear sole has the corresponding substantially elongated opening in which the stud slides in a bidirectional movement, the invention also allows the stud to be implemented on fixing it with an upper part located on the female part and its complementary side parts, and a lower part located on the interface with the footwear sole, provided with a central bore through which the rod of the female part will come out and will enable the corresponding screwing of the stud itself, the latter being able to optionally be formed without the emergent bolt and use a central bore in its upper portion with a greater diameter in which the rod of the female part will be screwed.
[0014] Obviously, a multidirectionally acting part can be placed in the slots existing on the footwear sole, the consequence thereof being that the stud can be provided with a lateral and angular mobility instead of a bidirectional mobility as in the previous case. In another embodiment the invention can be provided - in cooperation with the plan circular part having a rectangular opening - with an outer part attached to the surface of the footwear sole which has a cross-like slit, whereby it is made possible for the stud located on the central area to be oriented both forwardly and backwardly, or else rightwardly and letfwardly.
[0015] The invention is further implemented, if desired, by incorporating a plan circular part in the fixing area on the footwear, said part being provided with a central bore through which the upper rod of the stud enters, whereby the connection of all parts forming the connection area is consequently stiffened.
[0016] Finally, it should be noted that the invention allows the footwear sole to be provided with multidirectionally or bidirectionally fixing areas, which can be either all of them multidirectional or all of them bidirectional.
[0017] Obviously, the soles used for this type of anchorages are specifically shaped as far as the inclusion of the openings or bores is concerned, the same being able to be made in any sole considered as convenient and complying with the adaptation regulations.

PREFERRED EMBODIMENTS OF THE INVENTION
[0019] As shown in the above figures, it can be seen that the new arrangement for regulating multidirectional movements of the studs incorporated in sports footwear according to the invention consists of a metal part 4 having a plan rectangular shape, from which - namely from one of its major faces - an internally threaded or non-threaded, hollow cylindrical projection 3 emerges, which is adapted to enable the attachment of a bolt 2 stemming from the upper face of a stud 1 usable in sports footwear.
[0020] In figure 1 it is seen how the above described two parts are complemented with a part 5 which is circular in a plan view and has in its central area a quadrangular opening 5' adapted to enable the mobilization of the bolt 3 inside the opening 5', the female part 4 being held on the upper portion of the part 5 and the stud 1 being located inside the cylindrical projection 3 in accordance with the previous location of the female part 4 inside the opening 5'.
[0021] Obviously, the upper area of the stud 1 holds the footwear sole on the underside thereof and is consequently inmobilized.
[0022] In a second embodiment represented in figure 2, the stud 1 along with its threaded bolt 2' is incorporated inside the protuberance or cylindrical projection 3 of the female part 4, the action of the female part 4 being assisted or complemented by means of two side parts 6 and 6' which allow the stud to be mobilized when the same is located on the footwear sole.
[0023] As can be seen in figure 3, this second embodiment is implemented in accordance with the presence of a longitudinal opening 8' found in a reinforcemente 8 of the footwear sole, said opening forming on the upper side a recess inside which the female part 4 is inserted with the cylindrical rod 3 emerging, the female part being held or supported on the upper side by means of the two complementary fixing parts 6 and 6' acting as stops on sliding, while on the underside a part 9 is provided, which has a central bore 9' serving as an element that immobilizes the stud 1' and - in cooperation with the rod 2 - is engaged into the cylinder 3, whereby the elements shaped as the female part 4 and the stud 1' are suitably fixed, said part 9 having the function of keeping the anchorage clean and being preferably made of nylon.
[0024] Figura 4 shows how the invention can be constituted in a third embodiment using a shape and implementation of parts corresponding to the multidirectional embodiment, similar to the bidirectional one, since in this embodiment shown in said figure 4 the invention is implemented by means of an upper reinforcing area 10 located on the upper side of the circular part 4 provided with the quadrangular bore or opening 5', whereby this part - on incorporating the female part 4 from which the rod 3 will emerge - makes consequently possible for said rod to be inserted through a central opening 11' provided in a part 11 which, as seen in a plan view, is circular in shape and assumes a cross form, the rod 3 being consequently allowed to be located both to the right and to the left, or else in both a forward and rearward direction.
[0025] In order to keep the anchoring part clean, a circular part 12 is located, preferably made of nylon and provided with a central bore 12', whereby the threaded bolt 2' originated from the stud 1 can consequently be incorporated inside the cylindrical body 3 and in this way the whole set of parts is suitably positioned.
[0026] The part 11 is incorporated in the sole 20 of the footwear as shown in figure 5, but said sole 20 can also incorporate, as shown in figure 6, the embodiment formed by the parts 8 provided with their corresponding longitudinal openings 8' through which the rods 3 will emerge, and consequently it will allow the studs 1 to be located bidirectionally.
[0027] In figure 7 it can be seen how the sole 20', similar to the sole 20 represented in figure 6, has an inner area for locating the female part 4 and the side parts 6 and 6', the rod 3 emerging outwardly and the threaded protuberance 2' of the stud 1 being located inside the same.
[0028] In figure 8 it is seen the location of the studs 1 on a sole 20' that allows said studs to be located bidirectionally.
[0029] In figure 9 it is seen how the studs 1 emerge from the lower area of the sole 20' and are suitably located.
[0030] In figure 10 it is seen how the emergent openings, through which the female parts slide, appear on the inner side.
[0031] It is not considered necessary to make this description any longer so that anyone skilled in the art can understand the scope of the invention and the advantages derived from same.
