Description:
DESCRIPTION

DEVICE FOR POSITIONING STUDS FOR CYCLING SHOES.

Technical field

This invention relates to a device for positioning studs for cycling shoes. Notoriously in the cycling sector, with reference in particular to professional cycling, the positioning of the studs on the sole of cycling shoes is considered to be a very important operation, as it determines the position of the axis of the pedal of the bicycle relative to the foot of the cyclist, on which depends the degree of comfort and the optimisation of performance levels.

The foot of the cyclist is in fact the part of the body which transmits the work perfumed by the muscles of the lower limb to the pedal, and this action is mediated by the shoe and by the respective stud, housed on the sole. Therefore, an inadequate positioning of the foot relative to the axis of the pedal determines a dispersion of energy and, frequently, the occurrence of functional overloading of the ankle and knee joints.

Background art

Currently, in to determine the position of the stud on the sole of the shoe, manufacturers of cycling shoes provide spreadsheets in which, depending on the size of the shoe, the distance from the toe of the shoe is indicated, that is to say, from the end of the front portion of the shoe, which localises on the sole the coupling position of the stud.

The known reference spreadsheets are based on respective types of cycling shoes, so the coupling position of the stud indicated in them might not correspond at all to the most suitable position for the cyclist, considering the anatomical and anthropometric structure of the foot. Scientific research has in fact shown that feet of equal length may have different lengths and different inclinations of the axis passing through the metatarsal heads. This particular difference requires a greater attention to the coupling position of the foot to the pedal, that is, to the positioning of the axis of the pedal relative to the foot.

Disclosure of the invention

The need is frequently felt of providing a device for positioning studs for cycling shoes, comprising means for retaining the shoe configured to be fitted by a respective cycling shoe in such a way as to position it with the respective sole facing upwards. The retaining means comprise a rear end surface configured to at least partly abut with the rear portion of the seat of the foot of the shoe designed to house the heel. The device comprises means for indicating the coupling position of a stud on the sole of the shoe relative to the above-mentioned rear end surface of the retaining means. Advantageously, the device according to this invention defines the position for coupling the stud on the sole of the cycling shoe relative to a fixed reference corresponding to the foot of the individual, in particular to the end surface of the heel, and not with respect to the shoe, as mentioned above for the prior art.

Further features and advantages of the invention are more apparent in the detailed description below, with reference to a preferred, non-limiting, embodiment of a device for positioning studs for cycling shoes as illustrated in the accompanying drawings, in which:

- Figure 1 illustrates schematic perspective view of a device for positioning studs for cycling shoes according to this invention, in a non-operating position;

- Figure 2 illustrates a further perspective view of the device of Figure 1 according to a possible operating position;

- Figure 3 illustrates the device of Figure 1 during the positioning and the assembly of the stud on the sole of the shoe in a respective coupling position; - Figure 3a shows a further schematic perspective view of a detail of Figure 3.

Detailed description of preferred embodiments of the invention

With reference to the accompanying drawings, the numeral 1 denotes a device for positioning studs for cycling shoes.

The device 1 comprises means 2 for retaining a cycling shoe 3 configured to be fitted by the shoe 3, as illustrated schematically in Figure 3.

The retaining means 2 are configured in such a way as to position the shoe 3 with the sole 4 facing upwards.

Advantageously, the retaining means 2 have the shape comparable to a shoe model, an instrument known in the shoe wear technical sector.

The retaining means 2 have at least a rear end surface 5 configured to abut with part of the rear portion of the seat of the foot of the shoe 3.

The retaining means 2 have at least a front end surface 6 configured to abut with part of the front portion of the seat of the foot of the shoe 3.

The retaining means 2 have a top surface 7 designed to make contact at least partly with the seat of the foot of the shoe 3.

The top surface 7 is substantially flat.

Preferably, the top surface 7 is positioned substantially according to a horizontal plane.

The retaining means 2 comprise a first and a second side surface 8a and 8b each of which is joined to the rear end surface 5 and/or to the front end surface 6 and to the top surface 7, defining respective sides 8.

The first and second lateral surfaces 8a and 8b are designed to make contact with respective lateral portions of the seat of the foot of the shoe 3. Preferably, the retaining means 2 have a bottom surface 9 designed to make contact with the top surface of the seat of the foot of the shoe 3. The bottom surface 9 is joined to the top surface 7 and to the first and second lateral surfaces 8a and 8b.

The retaining means 2 comprise at least a first body 30, relatively fixed, and at least a second body 31 movable relative to the first body 30.

The first body 30 has at least the above-mentioned rear end surface 5. The first body 30 has the above-mentioned rear end surface 5, at least part of the top surface 7 and at least part of the sides 8 of the retaining means 2.

The first body 30 has a shape similar to a heel of the foot.

More specifically, the rear end surface 5 of the first body 30 simulates the end of the heel of the foot.

The second body 31 has at least the above-mentioned front end surface 6.

The second body 31 has the above-mentioned front end surface 6, at least part of the top surface 7, at least part of the sides 8 and the bottom surface 9 of the retaining means 2.

In other words, considering together the first and the second body 30 and 31 they have shape similar to an overturned foot.

In practice, once the shoe 3 is fitted on the retaining means 2, the first body 30 and the second body 31 are designed to be inserted in the seat of the foot of the shoe 3 respectively at the rear and front portion of the seat of the foot of the shoe 3.

According to this invention, the second body 31 is movable towards and away from the first body 30.

In this way, the positioning of the second body 31 relative to the first body 30 determines the longitudinal dimensions of the retaining means 2.

The longitudinal size of the retaining means 2 defines the measurement of the shod of the shoe 3.

Preferably, the positioning of the second body 31 relative to the first body 30 allows the shod of the shoe 3 to be defined, which is variable within a numerical range of from 36 to 46, included, according to the European measuring system.

In order to tension the shoe 3 once it has been fitted on the retaining means 2, the device 1 comprises elastic means 10 acting on the second body 31 of the retaining means 2.

The elastic means 10 are configured to oppose the movement of the second body 31 towards the first body 30.

In other words, the elastic means 10 are active in moving away the second body 31 from the first body 30.

The elastic means 10 may be, by way of example, in the form of a helical spring or elasticised cord.

In order to fit the shoe 3 on the retaining means 2, the second body 31 is moved toward the first body 30, opposing the elastic means 10, as schematically illustrated in Figure 1 .

Once the shoe 3 is fitted on the retaining means 2, the second body 31 is drawn by the elastic means 10 away from the first body 30, as schematically illustrated in Figure 2, until it comes into contact with the front portion the housing of the seat of the foot of the shoe 3, placing the shoe 3 under tension.

The device 1 comprises an element 1 1 for supporting the retaining means 2.

Preferably, the supporting element 1 1 is a bar, in particular with a rectangular or quadrangular cross section.

The device 1 comprises means 13 for connecting the first body 30 of the retaining means 2 to the supporting element 1 1 .

The connecting means 13 are connected to the supporting element 1 1 . The device 1 comprises means 14 for connecting the second body 31 to the supporting element 1 1 .

The connection means 14 of the second body 31 comprise a coupling element 12 slidably connected to the supporting element 1 1 .

The supporting element 1 1 defines a sliding guide of the second body 31 by means of the coupling means 12.

The coupling element 12 wraps around the supporting element 1 1 with clearance, to slide along it.

Preferably, the coupling element 12 comprises a first and second body connected to each other by means of a lead nut and screw type coupling. According to this invention, the device 1 comprises means 15 for indicating the coupling position of the stud 35 on the sole 4 of the shoe 3 fitted on the retaining means 2.

The indicator means 15 define the coupling position of the stud 35 relative to the rear end surface 5 of the retaining means 2.

The indicator means 15 are movable along a direction parallel to the retaining means 2, towards and away from an origin or fixed reference corresponding to the above-mentioned rear end surface 5 of the retaining means 2.

More specifically, the device 1 comprises a graduated reference scale 16 for positioning the indicator means 15 relative to the above-mentioned origin or fixed reference.

The graduated scale is preferably in centimetres, with details in millimetres.

The indicator means 15 are movable along the graduated scale 16.

The device 1 comprises means 19 for fixing the indicator means 15 in a respective position, relative to the fixed reference, in particular along the graduated scale and 16.

The fixed origin or reference of the graduated scale and 16 corresponds to the rear end surface 5 of the retaining means 2.

In order to display the coupling position of the stud 35 on the sole 4 of the shoe 3, the indicator means 15 comprise an emitter 17 of at least one laser beam 18 as reference of coupling position of the stud 35.

The reference position of the indicator means 15, in particular of the laser beam 18, is located on the portion of sole 4 positioned on the second body 31 of the retaining means 2.

The indicator means 15 comprise a tower 28 on the top of which is positioned the laser emitter 18.

It should be noted that laser emitter 18 is positioned at a height greater than the retaining means 2. The device 1 comprises a element 20 for supporting the indicator means 15.

The emitter 17 of the laser beam 18 is positioned along a direction parallel with the longitudinal extension of the supporting element 20.

In this way, the laser beam 18 is positioned at right angles to the supporting element 20.

More generally speaking, the reference position of the indicator means 15 is at right angles to the longitudinal extension of the supporting element 20.

Preferably, the supporting element 20 is a bar, in particular with a rectangular or quadrangular cross section.

The device 1 comprises means 26 for connecting the indicator means 15 to the supporting element 20.

The connecting means 26 are slidably connected to the supporting element 20 which defines a guide for sliding of the indicator means 15.

Preferably, the connecting means 26 comprise a slide 27 slidable on the supporting element 20, in particular a dovetail slide 27.

The above-mentioned means 19 for fixing the position of the indicator means 15 lock the sliding of the slider 27 along the supporting element 20. Preferably, the fastening means 19 comprise a grub screw which can be operated by means of a handle.

The slide 27 has a window 29 for detecting the distance, along the graduated scale 16, of the indicator means 15 relative to the fixed reference.

The support elements 1 1 and 20 of the retaining means 2 and the indicator means 15 are positioned parallel to each other.

The supporting elements 1 1 and 20 of the retaining means 2 and the indicator means 15 are connected by respective crosspieces 22, in particular a pair of crosspieces 22, positioned parallel to each other.

It should be noted that the elastic means 10 are preferably connected to one of the crosspieces 22. Preferably, the crosspieces have a shorter length than the supporting elements 1 1 and 20.

The supporting elements 1 1 and 20 and the crosspieces 22 give the device 1 a rectangular shape.

Advantageously, the supporting elements 1 1 and 20 and the crosspieces 22 give stability and rigidity to the device 1 .

The crosspieces 22 comprise respective supporting feet 32, in particular adjustable in height.

A further aspect of this invention is that it comprises at least one angular orientating device 23 of the coupling position of the stud 35 on the sole 4 of the shoe 3.

The angular orienting device 23 is configured to incline the stud 35 relative to a reference position or origin, in particular relative to the coupling position defined by the indicator means 15.

The angular orientating device 23 comprises an angular reference system 33, the reference position or origin of which corresponds with the coupling position of the stud 35 to the bicycle pedal.

With reference to the coupling position of the stud 35 indicated by the indicator means 15, in particular by the laser beam 18, the angular orienting device 23 is positioned in such a way that the reference position or origin of the reference system 33 of the angular orienting device 23 corresponds to the reference of the indicator means 15.

The reference system 33 of the angular orienting device 23 is a graduated sexagesimal scale.

Preferably, angular orienting device 23 has the shape of a disc.

The angular orientating device 23 has a respective seat 24 for housing and retaining a respective stud 35.

Preferably, the housing seat 24 is configured as a function of the shape of the stud 35.

More specifically, the shape of the housing seat 24 is such that, once the stud 35 is inserted in the housing seat 24, the reference line for coupling the stud 35 to the pedal corresponds with the reference position or origin of the reference system 33.

Advantageously, this technical feature is valid for a plurality of models of studs 35.

Advantageously, the seat 24 is a through seat to allow, on the one hand, positioning of the stud 35 in contact with the sole 4 of the shoe 3 and, on the other hand, acting directly on it for assembling it on the sole 4 of the shoe 3.

The angular orientating device 23 comprises, at one of its faces 23a, a raised edge 36 configured to define a supporting surface of the angular orientating device 23 on the sole 4 of the shoe 3, as illustrated in Figure 3a.

Preferably, the raised edge 36 extends around the perimeter of the seat

24 which houses and retains the stud 35.

For ease of use, the device 1 comprises one or more seats 34 for housing the angular orientating device 23, in particular positioned at one of the crosspieces 22 for connecting the supporting elements 1 1 and 20.

In use, the operator positions the indicator means 15 along the graduated scale 16 at a predetermined distance from the origin or fixed reference of the graduated scale 16, corresponding to the rear end surface 5 of the retaining means 2.

After reaching the desired distance along the graduated scale 16, the operator fixes the position of the indicator means 15, in particular acting on the fixing means 19.

It should be noted that the distance for positioning the indicator means 15 relative to the fixed reference of the graduated scale and 16 may be determined in several ways, such as, for example, measuring the foot of the cyclist in an analogue or digital manner.

Advantageously, the laser beam 18 defines visually the coupling position of the stud 35 on the sole 4 of the shoe 3 of the indicator means 15.

Subsequently, the operator positions the angular orienting device 23, which preferably already has in the relative seat 24 the respective stud 35, on the sole 4 of the shoe 3.

Advantageously, the raised edge 36 makes it possible to define a regular supporting surface on the sole 4 of the shoe 3.

More specifically, the operator positions angular orienting device 23 in such a way that the origin of the reference system 33 of the angular orienting device 23 coincides with the reference position defined by the indicator means 15, in particular by the laser beam 18.

In this way, the coupling position of the stud 35 to the pedal of the bicycle coincides with the reference position defined by the indicator means 15, in particular by the laser beam 18.

If it is not necessary to make any inclination to the coupling position of the stud 35 relative to the origin of the reference system 33 of the angular orienting device 23, the operator assembles the stud 35 directly on the sole 4 of the shoe 3, acting through the seat 24, in the coupling position indicated by the indicator means 15.

If it is necessary to make a certain inclination of the coupling position of the stud 35 relative to the origin of the reference system 33 of the angular orienting device 23, the operator rotates the angular orienting device 23, clockwise or anticlockwise, as a function of the graduated scale of the reference system 33, thereby positioning the stud 35 according to desired orientation, as schematically indicated in Figure 3.

At this point, the operator assembles the stud 35 on the sole 4 of the shoe 3 acting directly on it through the seat 24 of the angular orientating device 23.

Once the stud 35 is assembled on the sole 4 of the shoe 3, the operator withdraws the angular orienting device 23 from the sole 4 of the shoe 3 and the shoe 3 from the retaining means 2.

The invention described brings important advantages.

Compared with the prior art, the means 15 for indicating the coupling position of the stud 35 have as fixed reference the rear end surface 5 of the retaining means 2 which simulate the end of the heel of the foot.

Thanks to the angular orienting device 23 it is possible to position the stud 35 according to a predetermined inclination relative to the reference of the indicator means 15, complying with the natural spatial orientation of the foot, that is to say, its three-dimensional orientation.

This allows all the lower limb to move in a plane where the relative joints are aligned, completely eliminating torsional strains and parasitic forces which can result in annoying problems for the joints.

Further, since the retaining means 2 are configured for positioning the shoe 3 with the sole 4 facing upwards, the operator, having positioned the stud 35 according to the indicator means 15 and the angular orienting device 23, may assemble them directly on the sole 4 of the shoe 3.

In this sense, the device 1 may be defined as a workbench, since the operator can position the stud 35 on the sole 3 of the shoe 4 and assemble it without withdrawing the shoe 3 from the retaining means 2.
