The subject invention concerns a tool designed to remove such burrs and similar configurations from the ex¬ treme outer end of sport-shoe cleats that are present on said cleats originally and/or form on said cleats through wear.

Sport-shoes intended primarily for football but also for other sports are provided with a number of cleats for the purpose of maintaining and/or increasing the grip of the shoe against the support, such as turf. The cleats wear gradually, whereby undesired burrs form on the ex¬ treme outer cleat ends. When the cleats are completely worn down and/or when harder or softer cleats are desir¬ ed, the cleats mounted on the shoe may be unscrewed and be replaced by new cleats. However, also new cleats could still present burrs that have not been removed during the manufacture.

Attempts made hitherto to remove such burrs by means of e.g. steel brushes or coarse files have not been very successful. Not only is it a time-consuming task to brush or file away the burrs on the cleats, usually amounting so six or more on each shoe, but in addition the removed burrs clog the brushes or files rather rapidly, making it necessary to clean them comparatively often.

The purpose of the subject invention is to provide a tool which is able to rapidly and efficiently and without any risks for clogging remove the burrs in question from sport-shoe cleats.

This purpose is achieved in accordance with the in¬ vention in that the tool has a body with a socket formed therein for reception of a holder on which is mounted a plurality of cutting blades directed essentially radially towards a common central axis, the cutting edges of said

blades extending essentially obliquely axially upwards/ /outwards and arranged to be placed over the extreme outer end of a cleat in order to cut away said burss from the extreme end of the cleat upon rotation of said tool. The invention will be described in closer detail in the following with reference to the accompanying draw¬ ings, illustrating an embodiment of the tool in accor¬ dance with the invention that at present is the preferred one. In the drawing, Fig. 1 illustrates a tool in a perpective view as seen obliquely from above, some parts having been broken away from clearer illustration of components behind, and

Fig. 2 is a lateral and partly broken view of the tool and of a part of a sport-shoe with cleats thereon, in order to illustrate the function of the tool in accor¬ dance with the invention in closer detail.

The tool in accordance with the invention, designa¬ ted generally by reference 1 in the drawing, is primarily designed to remove such burrs 2 or the like from the ex- treme outer end 3 of cleats 4 on sport-shoes 5, one ex¬ ample of which is illustrated in Fig. 2, as are present on said cleats from the beginning, i.e. have not been re¬ moved in connection with the manufacture, and/or gradual¬ ly form on said cleats through wear. Obviously, the tool in accordance with the invention could also be used within other areas where there is a need for removing burss or like structures on tubular or rod-like objects.

In accordance with the preferred embodiment illust- rated in the drawing, the tool 1 comprises a body 6 which is shaped essentially as a rectilinear circular cylinder serving as a gripping means, allowing the tool 1 to be rotated manually, and in order to facilitate the rotation the tool it is preferably formed with a knurled jacket surface. The body 6 could be made from any suitable mate¬ rial, but metal, e.g. light metal or plastics are most suitable in this connection.

At its outer free end the body 6 comprises a socket 7 configured as a recess 8 in which a cutting-blade hol¬ der a to be described in closer detail in the following is secured by means of a suitable fastener 10, in accor- dance with the example shown in the form of a screw.

The socket 7 in the form of a recess 8 serves to re¬ ceive the above-mentioned cutting-blade holder 9 and a number of cutting-blades 12 directed essentially radially towards a common central axis 11 are mounted on the hol- der 9 and preferably they are made from e.g. steel, pre¬ ferably hardened steel. The cutting edges 13 of the bla¬ des 12 in accordance with the embodiment illustrated in the drawings extend essentially obliquely axially upwards/outwards and they are arranged to be placed over the extreme outer end 3 of a cleat 4 made from plastics or rubber possessing suitable characteristics for the in¬ tended purpose, whereby by rotating the tool 1 around the central axis 11 it becomes possible to cut away the burss 2 on the extreme outer end 3 of the cleats 4. More precisely, in accordance with the illustrated embodiment the cutting-blade holder 9 comrpises a plura¬ lity of slits 4 which are directed essentially radially towards the central axis 11 common to all cutting blades, for reception in each slit of one cutting blade 12. The cutting-blade holder 9 is formed with an essentially centrally located depression 15 of a preferably frustro- conical configuration, the wider end of which is turned towards the outer free end of the body 6.

Also the recess 8 formed in the body 6 is configured essentially as a truncated cone widening outwards, tow¬ ards the outer free end of the body, and also the cut¬ ting-blade holder 9 has an external configuration of an essentially matching shape. Intermediate the frustro- conical inner face 16 of the recess 8 and the frustro- conical external face 17 of the cutting-blade holder 9 an annular space or gap 18 is formed.

By designing the slits 14 formed in the cutting- blade holder 9 as through-slits, the edges 13 of the cut¬ ting blades 12 may be positioned inside the depression 15 while their end portions 19 facing away from the edges 13 may project into the annular space 18.

The end portions 19 of the blades 12 projecting into the annular gap 18 are bent in the manner illustrated in the drawing figure and preferably they are doubled in such a manner that when the cutting-blade holder 9 is mounted in position in the recess 8 of the body 6 the end portions 19 are clampingly received inside the gap 18, the cutting blades 12 thus being prevented from moving.

In order to achieve the desired deburring result the number of cutting blades 12 should be at least three, and in accordance with the shown embodiment six blades are provided. Thus, the number of cutting blades could be al¬ lowed to vary freely within rather wide limits. Should one or some cutting blades 12 be worn or be rendered in¬ efficient in some other way they are preferably deta- chably mounted in the cutting-blade holder 9 so as to allow replacement of the blade (s) concerned after loose¬ ning of the fastener 10 and removal of the cutting-blade holder 9 from its recess 8, whereupon the blades may be pulled upwards, dislocating them from its associated slit 14.

The function of the tool described in the aforegoing and illustrated in the drawings should be self-evident and appears clearly from Fig. 2. Prior to the deburring the cleat 4 is configured as illustrated to the left in drawing figure 2 and comprises burrs 2. The latter are removed by applying the tool 1 over the cleat 4 in ques¬ tion and rotating the tool manually over one or a couple of turns. The end result appears from the cleat 4 to the right in the drawing figure 2. Obviously, the invention should not be regarded as limited to the embodiment illustrated in the drawings and

described above but could be modified in many ways within the scope of the claimed protection.
