ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to the field of devices for fixing and removing seats used to fasten studs under the sole of a boot, for example a sports boot such as a football boot.
Boots may be provided with two types of seat. A first type is fixed, embedded in the material forming the sole of the boot. A second type may be removed and replaced, being fastened from the inside of the boot. It is understood that the fixing or removal of such bases from the inside of a boot, which is a location to which there is poor access, is a difficult operation. With this type of seat, the sole is pierced through its entire thickness with a number of holes corresponding to the number of studs which it is desired to fit. The operator, during manufacture of the boot or during the changing of a seat, takes a seat and arranges it, from the inside of the boot, in the hole for which it is intended. The operator then exerts a force on the seat in order to secure it to the sole, by causing spikes in the seat to penetrate the material of the sole and so that the upper face of the seat is flush with the surface of the sole so as not to make the boot uncomfortable to wear. The operator then screws in a stud from underneath the sole.
During removal of the seat, firstly the stud is unscrewed, the seat being secured in rotation with the sole by means of its spikes, and then pulls out the seat before fitting a new one.
The French patent published under no. 2 720 967 discloses a pincer with two articulated branches, one side serving as handle and the other side serving as jaws for fixing and removing the seats. The jaws are able to receive a removable pin for the removal of seats and accessories which make it possible to screw in and to unscrew the various types of studs. A pincer provided for screwing in/unscrewing two types of studs thus comprises four components in total. Moreover, during fixing or removal of seats, the boot is placed between the jaws of the pincer and the top or vamp of the boot is also gripped between the said jaws. This pincer operates satisfactorily, but it is bulky and relatively cumbersome to use and is thus not suited to being placed in a garment pocket. The pincer comprises four components in total, three of which are small, which presents a risk of loss, for example on a football pitch.
SUMMARY OF THE INVENTION
The object of the invention is to remedy the drawbacks of the aforesaid pincer and to propose a device for fixing and removing seats which is compact, lightweight and reduces the risk of components being lost.
The fixing and removal device, according to the invention, is provided for boot stud seats. The seats are intended for fitting from above a boot sole and for receiving studs screwed in from underneath the sole. The device comprises a first portion forming a handle provided with a means for fixing seats on a first face and a second portion forming a handle provided with a means for removing seats from a first face. The first face of the first portion is capable of being fitted into a second face of the second portion and the first face of the second portion is capable of being fitted into a second face of the first portion. A device which can be used for fixing and removing seats by means of two components of substantially identical dimensions, which reduces the risk of the components being lost, is thus made available.
In one embodiment of the invention, the two portions fitted into each other are the length of a user's hand. The device is easily stored in a garment pocket.
Advantageously, the fixing means comprises a planar bearing surface projecting with respect to the first face of the first portion and a threaded pin projecting with respect to the said planar bearing surface. It is thus possible to fix a seat by forcing it into the material of the sole by means of a pulling force obtained by screwing the threaded pin into the seat while bearing on the underside of the sole. This avoids the vamp being crushed.
In one embodiment of the invention, the planar bearing surface has a hexagonal shape.
In one embodiment of the invention, the removal means comprises a cylindrical bar projecting with respect to the first face of the second portion. Removal is achieved by inserting the cylindrical bar into the hole provided for the stud and by exerting a pushing force on the device.
In one embodiment of the invention, the second face of the first portion comprises a first means for screwing in/unscrewing studs and the second face of the second portion is provided with a second means for screwing in/unscrewing studs. The device is thus capable of being adapted to two different types of studs while comprising only two components.
Preferably, the first face of the first portion and the first face of the second portion are capable of being fitted together. The device thus offers no roughness.
The threaded pin of the first face of the first portion may project inside a hole provided in the bar of the first face of the second portion and the said bar is able to project into a hole provided between the threaded pin and the planar bearing surface of the first face of the first portion and the said planar bearing surface is able to project into a hollow provided around the bar, in a first face of the second portion.
In one embodiment of the invention, the second face of the first portion has a hexagonal shape provided in order to fit into a hollow of corresponding shape of the first face of the second portion. The two portions are thereby secured in terms of rotation.
The first face of the first portion can comprise a protuberance of hexagonal shape provided in order to fit into a hollow of adapted shape of the second face of the second portion. In this case also, the two portions are secured in terms of rotation.
Produced in this way, there are three fitting options for the device, the first for fixing seats, the second for removing seats and the third for the instantaneous change from one type of stud to another, there being, in all three cases, axial securing by fitting and securing in terms of rotation on account of complementarity of shapes between the two portions.
