Definitions

• the present invention relates to a shoe of the in-line wheel type constituting Dar a chassis on an upper plate of which is fixed the sole of a shoe and comprising a lower longitudinal part on which the wheels are arranged.
• This type of skate is intended for the training of skaters on ice outside the rink, but also for any sportsman wishing to maintain or improve on hard paved, cemented ground, etc. the techniques used in sliding sports such as downhill skiing, cross-country skiing, ice skating, etc.
• This is how the practice of this sport includes a motor or propulsive phase by causing the skate to diverge towards the outside and taking lateral support on the wheels thus inclined in the manner of a shift, then a sliding phase is effected by repositioning the wheels perpendicularly to the ground
• the invention relates to a shoe of the in-line wheel type constituted by a chassis on an upper plate of which is capable of being fixed a shoe and comprising a longitudinal lower part on which the wheels are arranged, characterized in that at minus one of the wheels central units is arranged on an independent support connected with respect to the chassis by means of removable fixing means and in that means are provided for adjusting the height of the running surface of said wheel relative to the running surface of the wheels. end on the ground, so as to constitute an intermediate rolling zone of variable height with respect to the rolling plane of the end wheels.
• the invention therefore makes it possible to obtain a versatile skate only by changing or adjusting the central wheels with respect to the end wheels, and therefore without requiring a change of the complete running gear.
• the present invention also relates to the characteristics which will emerge during the description which follows and which should be considered in isolation and according to all their possible technical combinations. This description given by way of nonlimiting example will make it easier to understand how the invention can be implemented, with reference to the attached schematic drawing in which:
• FIG. 1 is a side view of an inline skate and an associated shoe, according to a first embodiment of the support, in a first "anti-rockering" or “fitness” position,
• FIG. 2 is a side view of the skate of FIG. 1 but in a second "rockenng" position
• FIG. 3 is a side view of an inline skate and an associated shoe, according to a second embodiment of the support in a first "anti-rocke ⁇ ng" or “fitness” position,
• FIG. 4 is a side view of the skate according to FIG. 3 but in a second "rockenng" position
• FIG. 5 is a side view of an inline skate and an associated shoe, according to a third embodiment of the support, in a "street aggressive" position,
• FIG. 6 is a side view of an inline skate according to a fourth embodiment of the support in a first "anti-rocke ⁇ ng" position
• FIGS. 1 and 2 are side views of the skate of Figure 6 in a second position called "rockenng".
• the shoe 1 shown in FIGS. 1 and 2 consists of a frame 5 on an upper plate 4, of which is able to be fixed a shoe 2.
• the shoe is with four wheels 6, 6A, 6B - it could have more of them - and the central wheels 6A and 6B are arranged on an independent support 11 connected with respect to the chassis 5 by means of removable fixing means 13, 15, and having means for adjusting the height of said wheels 6A, 6B, with respect to the running surface "P" of the end wheels 6 on the ground “S", so as to constitute an intermediate rolling zone allowing the skater to modify, as he pleases, his support points according to the type of skating to be practiced.
• the independent support 11 is constituted by two flanges 14 interconnected by two axes 12A, 12B, corresponding to the two axes of rotation of the two central wheels 6A, 6B.
• the support 11 has an asymmetrical shape with respect to a longitudinal axis XX 'on which are arranged the axes 12A, 12B, of the two wheels 6A, 6B, so that its 180 ° reversal on itself around this axis and / or in a vertical plane causes a change in height of said wheels 6A, 6B, relative to the rolling plane "P" of the end wheels 6, namely an uplift or as the case may be a lowering of these relative to said plane "P", according to a value "a” equal to the difference between the distance "b", which separates the lower edge 14b of the support 11 and its longitudinal axis XX ', and the distance "ç" separating its upper edge 14a from the same axi
• the support 11 comprises, near one end of the upper edge 14a, and near an opposite end of the lower edge 14b, an indexing projection 16, 17, able to cooperate round in turn depending on the chosen position, with a corresponding single housing 18 formed in a lower part 5a of the chassis 5, so that after a reversal of the support by 180 ° in a vertical plane, or around the axis XX ' , one of the projections 16 or 17 cooperates with the single housing 18 for perfect alignment of the longitudinal axis of the support with that of the chassis.
• other indexing means can be provided.
• the support 11 is ellipsoidal in shape, each of the upper 14a or lower 14b edges of which is capable of cooperating with the corresponding lower part 5a of the chassis 5, depending on its position.
• a reversal of the support only around its axis XX ' would require the provision of an additional associated housing 18 to receive the projection 17 or 16 as appropriate.
• the sucport 11 A essentially differs from the previous support 11 in that it is produced from a rectangular element also asymmetrical on the longitudinal sides of which recesses have been made 19 , 20, of different depths, so that the longitudinal axis XX ′ passing through the axes OO ′ of the central wheels is disposed asymmetrically with respect to the upper 14Aa and lower 14Ab edges of said support 11 A.
• the support 11 B is formed by an element carrying two wheels 6C, 6D, arranged on the same longitudinal axis XX 'as the wheels end 6, but of a smaller diameter "d” so as to cause the detachment of these wheels 6C, 6D, relative to the rolling plane "P" of said end wheels 6 to facilitate obstacle clearance and sliding on metal barriers.
• the value of the separation "a” will depend on the difference in diameter between the central and end wheels.
• the detachment could also be modified for example by interposing a washer between the chassis 5 and the support 11B at the level of the fixing means 15.
• the spacing "H" of the vertical axes ZZ 'of the central wheels 6C, 6D is provided so as to stretch and bring these wheels 6C, 6D closer to the end wheels 6, this center distance " H "being at least greater than the center distance” J "of each of the end wheels 6 and of an adjacent central wheel 6C or 6D.
• the removable fixing means of the independent supports 11, 11A, 11B, of the central wheels 6A, 6B - 6C, 6D consist of a screw 15 passing through it axially and screwing into a corresponding threaded hole 13 of the chassis 5.
• the support 11 D differs from the previous supports 11 and 11A in that the upper edge 14Da represents two projections 24, of the same height, but arranged asymmetrically with respect to the means fixing 15 and able to cooperate with two series of associated notches 34, 35 respectively, of different height to obtain the height adjustment of the support 11D.
• the support 11 in a first position, shown in Figure 6, the support 11 is positioned so that the projections 24 are housed inside the notches 34 which have substantially the same depth as these projections.
• the support 11D is "raised” to the maximum with respect to the chassis 5 and the axes of the central wheels 6A, 6B, are carried by an axis XX 'coincident with the axis YY' passing through the axes 12 end wheels 6.
• a single projection 24 could be provided instead of two.
• the advantage of such an embodiment is that it suffices to loosen the screw 15 by a value at least equal to "a”, and to rotate the support 11 D by 180 ° around a vertical axis, so that its projection (s) engages in the other series of notches 34 or 35 as the case may be, to modify the height of the wheels, without having to remove the screw 15, even to return the support 11 D on itself.
