Definitions
- the present invention relates to a skate with aligned wheels.
- Skates are known which are constituted by a support for an item of footwear from which wings protrude, mutually aligned wheels being pivoted between the wings; the use of these skates is aimed in an increasingly specific manner to the sports practice of speed skating or slalom.
- the skating direction is changed by the athlete by means of the movements of the foot transmitted directly to the skate.
- a sports implement mainly used by skiers for summer training on roads, is also known which is composed of a support for an item of footwear from which a frame protrudes downward and centrally; the ends of two pairs of wheel supporting trucks are independently pivoted to the frame, and the head of a screw is connected to the support.
- the screw is provided with a threaded stem with which a complementarily threaded nut is associated and abuts on the ground-facing surface of a connecting element which is arranged transversely to each pair of trucks.
- a spring is arranged coaxially to the stem.
- the skate When the adjustment of the spring is at its minimum value, i.e. when the spring is not compressed, the skate is adapted to slaloming, however the skate yields in the pushing action and when skating in a straight path, with a considerable deterioration of the athletic performance.
- This condition can allow to improve the use of the implement in the practice of slalom, but this again entails a non-optimum and thus unstable condition during straight paths and thus in the practice of speed skating.
- the adjustment of the spring allows only to vary the condition of use of the implement in the sports practice of slalom.
- One aim of the present invention is to eliminate the problems described above in conventional skates by providing a skate with aligned wheels wherein it is possible for the user to achieve, according to the requirements, optimum maneuverability and ease of execution in the practice of slalom and optimum use in the practice of speed skating.
- Another important object is to provide a skate wherein the maneuverability characteristics can be changed by the user according to specific requirements, such as the type of use or the personal skill level, without affecting the trim of the skate.
- Another important object is to provide a skate with aligned wheels which allows to achieve both a very tight and as uniform as possible curving radius and, in other conditions, a straight path which can be easily controlled.
- Another important object is to provide a skate wherein curving can be achieved easily for the athlete, requiring very little effort.
- Another important object is to provide a skate which is structurally simple and can be obtained with conventional machines and facilities.
- Not least object is to provide a skate which associates with the preceding characteristics that of being reliable and safe in use.
- a skate with aligned wheels comprising a support for an item of footwear from which a frame protrudes downward, an end of at least one pair of wheel supporting trucks being pivoted to said frame, a connecting element protruding below said support, characterized in that at least one member for adjusting the compression of at least one resilient member is associated, so that it can rotate, with said connecting element, which is freely associated with said support at one end, said resilient member interacting with a linking element for said at least one pair of trucks, a means being provided for rotating said connecting element.
- figure 1 is a partially sectional side view of the skate, according to the invention
- figure 2 is a sectional view of the compression adjustment member in the position of maximum stroke allowed to the resilient member
- figure 3 is a view, similar to the preceding one, in the position of minimum stroke for the resilient member
- igure 4 is a front sectional view of the compression adjustment member, according to a further aspect of the invention, in the position of maximum stroke
- figure 5 is a view similar to the preceding one, in the position of minimum stroke
- figure 6 shows a detail of the adjustment member of figures 4-5, in a partially sectioned view
- figures 7 and 8 are top views respectively of the support member and of the adjustment member of figures 4-5.
- a skate according to the invention generally designated by the reference numeral 1, comprises a support 2 for an item of footwear 3.
- a frame 5 protrudes downward, preferably approximately at the median region 4 of the support 2.
- the first ends 6a and 6b of two trucks, designated by the numerals 7a and 7b, are independently pivoted on the frame, and a plurality of wheels 8 is pivoted between the trucks; the wheels are mutually aligned.
- a pair of first seats 11a and lib is arranged, below the support 2, at the heel region 9 and at the tip region
- lib there is a connecting member having a plate, designated by the numerals 12a and 12b which is respectively arranged at each seat 11a, lib and is adapted to rotate.
- the connecting member protrudes below the support 2 between each pair of trucks 7a and 7b in the interspace between two mutually adjacent wheels 8.
- the connecting member is constituted by a screw which has a threaded stem, designated by the numerals 13a and 13b, which is connected to the plate 12a and 12b and has a head, designated by the numerals 14a and 14b, which is provided with adapted notches for the use of tools such as a screwdriver.
- the threaded stems 13a and 13b and the heads 14a and 14b rotate freely within complementarily shaped second seats
- the skate 1 also includes an adjustment member for adjusting at least one resilient member which is preferably constituted by one or more rubber pads or by a spring, designated by the numerals 17a and 17b, which is arranged coaxially to the threaded stems 13a and 13b.
- the adjustment member is constituted by a pair of profiles 18a and 18b which have the shape of an inverted cup and on whose base 19, which is directed toward the support 2, there is a hole 20 which is threaded complementarily with respect to the stems 13a and 13b.
- each profile 18a and 18b are advantageously arranged approximately at right angles to the underlying pair of trucks, and are guided, in their stroke, by adapted wings 22a and 22b which protrudes at right angles to the support 2.
- Each spring 17a and 17b is thus interposed between the bases 19 of the profiles 18a and 18b and the cross-members
- skate 16a and 16b which link each pair of trucks 7a and 7b.
- the use of the skate with aligned wheels is as follows: by acting at the heads 14a and 14b, the user can adjust the extension of the spring 17a and 17b, varying the position of the profiles 18a and 18b with respect to the support 2.
- Actuation of the spring compression adjustment member in fact allows to keep the wheels 8, which are pivoted at the second ends 23a and 23b of each pair of trucks 7a and
- Figures 4-8 show an adjustment member, according to a further aspect of the invention, comprising two springs 117 and wherein like reference numbers denote similar features to those of figures 1-3.
- the connecting member includes a screw 112 connecting a first bush 113 with the support 2.
- First bush 113 is externally threaded and is associated with a second bush 114 having an internal threading.
- Second bush 114 also has a seat 115 for engaging a tool adapted to rotate the bush 113.
- Second bush 114 is associated with a spring presser 121.
- a spring holder 116 is slidingly associated with second bush 114 and springs 117 are arranged between spring holder 116 and spring presser 121.
- the spring load can be adjusted between a position of minimum load (figure 4) and a position of maximum load (figure 5).
- the user can also select all the positions which are intermediate between the two extreme ones, in which the spring is packed and in which the spring is maximally extended, so as to be able to change the maneuverability characteristics of the skate according to specific requirements such as the type of use or the level of skill achieved.
- the user can thus use a skate with aligned wheels which allows to achieve a very tight and uniform curvature radius or an easily controllable straight path.
- skate thus conceived is susceptible to numerous modifications and variations, all of which are within the scope of the inventive concept.
- only one wheel supporting truck might be pivoted to the frame 5, the remaining wheels being articulated directly to the frame 5.
