Definitions
- the present invention refers to an in-line roller-skate, in particular a racing skate, provided with wheels featuring an oversized diameter.
- Racing-type in-line roller-skates as they are currently used to competitive purposes, are generally provided with wheels having standard-sized diameters of either 80 mm or 84 mm, depending on the characteristics of the skate and the particular needs of the user, while the connection of the sole of the footwear to the chassis of the skate takes place with a pre-defined centre-to-centre distance of 165 mm.
- second wheel the wheel situated immediately behind the front wheel
- Such a contrivance is necessary in order to be able to keep the height of the chassis in relation to the rolling plane within acceptable limits: in correspondence of the place in which said second wheel is accommodated, in fact, the chassis must also be capable of accommodating in its interior the screws or the rivets for the connection of the toe of the footwear to the same chassis.
- an important purpose of the present invention is to provide a skate with oversize-diameter wheels, which has such features as high stability, high leading and running precision and speed, while keeping the height of the chassis in relation to the rolling plane substantially unaltered.
- Another purpose of the present invention is to provide an in-line roller-skate, in which the footwear and chassis assembly has a greater torsional rigidity.
- a further, equally important purpose of the present invention is to provide an in-line roller-skate at competitive costs, which is in addition capable of being manufactured with the use of existing techniques and tools.
- FIG. 1 is a side elevational view of a racing roller-skate with oversize-diameter in-line wheels according to the prior art
- FIG. 2 is a side elevational view, similar to the one appearing in FIG. 1 , of a racing roller-skate with oversize-diameter in-line wheels according to the present invention.
- the reference numeral 1 is used there to generally indicate a racing skate with oversize-diameter in-line wheels according to the prior art; this skate 1 comprises a footwear 2 , which is provided with a sole 3 featuring binding points 5 and 6 for attachment to the chassis 4 , which are provided in the heel-piece zone and in the metatarsal area of the foot, respectively.
- the connection of the footwear 2 with the chassis 4 is carried out by means of such known fastening means 7 as screws or rivets.
- Rotatably associated to the chassis 4 are three larger-diameter wheels 8 , generally with a diameter sized to 100 mm, and a wheel 9 , or second wheel, having a standard diameter (i.e. 80 mm or 84 mm) and positioned behind the front wheel.
- the second wheel 9 in order to be able to keep the height H of the chassis 4 unchanged in relation to the rolling plane 10 , the second wheel 9 must have a smaller diameter than the remaining wheels of the skate, so as to allow for the accommodation, inside the chassis 4 , of the fastening means 7 needed to secure the footwear 2 to the same chassis 4 in correspondence of the second binding point 6 .
- This prior-art solution entails the drawbacks that have already been elucidated earlier in the introductory part of this description.
- FIG. 2 illustrates a racing roller-skate with oversize-diameter in-line wheels according to the present invention.
- the skate 101 comprises a footwear 102 provided with a sole 103 , which feature at least two binding points 105 and 111 for attachment to the chassis 104 ; the first of such binding point 105 is positioned in the heel-piece zone of the sole, whereas the second binding point 111 is positioned in proximity of the toe zone of the foot, approximately in the area in which the juncture of the toes lies.
- the connection of the footwear 102 with the chassis 104 is carried out by means of such known fastening means 107 as screws or rivets.
- the second binding point 111 i.e.
- the front one turns therefore out as being situated at a greater distance from the first binding point 105 , i.e. the rear one, as compared with the prior-art solution.
- the centre-to-centre distance between the first binding point 105 and the second binding point 111 is comprised between 170 mm and 210 mm, or shows an increase comprised between 3% and 27% over currently used centre-to-centre distance values; a preferred value for such a centre-to-centre distance is 195 mm.
- the chassis 104 is capable of accommodating a train of wheels 108 comprising solely oversize-diameter wheels, while at the same time accommodating the fastening means 107 for the footwear 102 in its interior, wherein the height H of the front zone of the chassis 104 in relation to the sliding plane 110 is kept unaltered.
- the chassis 104 is capable of accommodating a train of wheels 108 comprising solely oversize-diameter wheels, while at the same time accommodating the fastening means 107 for the footwear 102 in its interior, wherein the height H of the front zone of the chassis 104 in relation to the sliding plane 110 is kept unaltered.
- four wheels 108 having an oversized diameter, advantageously a diameter of 100 mm, in an in-line arrangement. It will be readily appreciated, however, that skates according to the present invention can equally well be provided with in-line arrangements of even five wheels.
- the skate provided with a chassis of an unaltered height H in relation to the sliding plane, and supporting a complete train of unvaryingly oversize-diameter wheels, enables high performance levels to be obtained, while at the same time keeping the height of the centre of gravity of the skater unaltered.
- the skate according to the present invention has characteristics of high stability, high leading and running precision, as well as increased speed thanks to the greater propelling power deriving, among other things, from a lower loss of energy due to vibrations and instability of the skate.
- Such an improvement of the performance level of the skate is also due to a greater torsional rigidity of the footwear-chassis assembly, which are in fact assembled together with a greater arm owing to the increased centre-to-centre distance between the binding points joining the two parts together.
- Such a feature also contributes to a faster response of the skate to leading commands during running, and is effective in reducing vibrations coming from the chassis.
- skate may of course be the subject of a number of modifications and variants, also in connection with different applications, without departing from the scope of the present invention.
- materials used to manufacture the skate of the present invention, as well as the shapes and the sizing of the individual component parts thereof, may each time be selected so as to more appropriately meet the particular requirements or suit the particular application, again without departing from the scope of the present invention.
