Definitions

  • the present invention relates to a roller skate made entirely of plastic, of the type comprising a platform in two front and rear parts telescopically connected to each other, each front and rear platform carrying the axis of rotation of the front and rear wheels, a system for adjusting and locking the two platforms with respect to each other in the desired position, a front shell fixed on the front platform and a rear shell fixed on the rear platform capable of retaining the shoe on the roller skate by means of at least one tightening strap.
  • the object of the present invention is to produce a skate of this type which is inexpensive to manufacture but which nevertheless has all the possibilities of suspension and steering flexibility and the qualities of resistance of current skates and which is also easy to adjust in length.
  • the adjustment and blocking system of the two platforms relative to one another is formed, on the one hand, by a rack formed on a part of a first platform able to extend under the second platform and, on the other hand, by a toothed tongue integral with the second platform and able to be engaged in the rack of the first platform.
  • the tongue is pivotally mounted on the second platform and is able to be engaged in the rack and to be held there by means of a lever forming a cam.
  • the tightening of the roller skate is carried out by means of a single strap and a plate for distributing the tightening force on the instep is provided on the front shell.
  • each roller skate has suspension and damping means.
  • the roller skate according to the invention comprises two front (1) and rear (2) platforms each carrying the axis (3) of rotation of the wheels (5) of the roller skate .
  • Each platform (1,2) is provided with a shell respectively (7,8) forming front and rear toe clips and carrying the fixing strap (9).
  • FIGS. 2 and 3 The shape of the front (1) and rear (2) platforms is shown more particularly in FIGS. 2 and 3.
  • the front platform (1) consists of a longitudinal beam (11) carrying at its front end two bent arms (12,13).
  • the bent arm (12) located outside forms at its free end the hub (12a) carrying the axis (3) of the front wheels (5).
  • this arm (12) The plastic material from which this arm (12) is formed allows a certain bending of the latter creating a suspension effect.
  • This flexing effect of the arm (12) is limited by the arm (13) located inside of it.
  • This arm (13) has, in fact, substantially the same shape as the arm (12) but is more rigid than the latter because it is double and therefore less flexible.
  • This arm (13) has a semi-cylindrical cavity (13a) capable of receiving the part (12a) of the arm (12) forming a hub during bending of the latter.
  • the bent arm (12) also has at its end, on its part (12a) forming a hub, a lug (12b) projecting radially in the horizontal direction.
  • This lug (12b) cooperates with an associated recess (13b) formed at the free end of the arm (13) to allow a certain transverse tilting of the hub part (12a), corresponding to the creation of a steering angle.
  • a braking pad (4) of known type can be fixed on the suspension arm (12) as shown in FIG. 1.
  • the beam (11) of the front platform has, in cross section, substantially the shape of a C (see FIG. 3) delimiting two lateral grooves forming slides (15).
  • This beam (11) also has a central longitudinal cutout (16) extending approximately from its middle to its rear end.
  • An elastic tongue (17) is pivotally mounted at (18) on this beam, and is able to move in its cutout (16).
  • This tongue (17) is provided at its free end with teeth (17a) whose role will be explained below.
  • a lever (19) is also pivotally mounted at (20) at the rear end of the cutout (16).
  • This lever (19) has a part forming a cam (19a) capable of pressing on the end of the tongue (17) and a part (19b) allowing actuation.
  • the rear platform (2) is also formed by a longitudinal beam (21).
  • this beam (21) has at its rear end two bent arms (22,23), the bent arm (22) located outside forming a hub at (22a) and carrying the axis (3) of the rear wheels (5), and the two arms (22,23) forming a suspension whose flexion is limited, on the one hand, by the cavity (23a) of the arm (23) and, on the other hand part, by the stop (24).
  • a lug (22b) of the arm (22) allows, with an associated recess (23b) of the arm (23), a certain transverse tilting of the hub (22a).
  • the beam (21) of this rear platform (2) has, in cross section, the shape of an inverted ⁇ capable of engaging by each of its wings (25) in the slides (15 ) of the front platform (1).
  • the bottom (26) of this ⁇ -shaped beam forms a rack whose teeth correspond to that of the tongue (17).
  • the rack and pinion assembly (26), tongue (17) and lever (19) allows the length of the roller skate to be adjusted.
  • lever (19) can then be easily pivoted upwards by actuating its part (19b), by simply engaging a finger in the cutout (16) and pushing this part (19b) towards the high.
  • the front shell (7) of the roller skate is made up of two parts (27,28).
  • the part (27) of this shell has a base (29), the cross section of which is complementary to that of the platform (1) at its front part and which is capable of being placed thereon by sliding and to be fixed by gluing or the like.
  • the upper part of this shell (7) substantially matches the shape of the end of a shoe.
  • This part (27) further comprises a longitudinal slot (30) barred at its upper end by a transverse edge (30a) of the shell (27).
  • the other part (28) of the front shell is formed of a plate capable of substantially matching the shape of an instep.
  • This plate (28) is provided with a tongue (31) capable of sliding by means of a lug (32) in the slot (30) of the part (27) of the front shell (7).
  • This tongue (31) also has at its free end a flange (33) capable of abutting against the transverse edge (30a) of the shell (27) so as to stop the movement of the plate (28).
  • This plate (28) also has a recess (34) for the passage of the fixing strap (9).
  • the rear shell (8) of the roller skate forms a rear toe clip.
  • this rear shell has a base (35) of cross section complementary to that of the platform (2) at its rear part and which is suitable for being placed thereon. by sliding and to be fixed by gluing.
  • This rear shell (8) has, in addition, two lateral wings (36) able to come on either side of the foot and a rear wing (37) capable of pressing against the rear of the shoe.
  • the roller skate according to the invention can be fixed using a single strap (9), in particular thanks to the plate (28) of the front shell forming a plate distribution and being adjustable relative to the part (27) of this front shell, by its sliding in the slot (30) thereof.
  • Figure 4 shows another embodiment of the shoe according to the invention can be tightened with two strips and not just one as in the previous example.
  • the front and rear platforms are identical to those of the previous example, and will therefore be designated by the same references (1,2), as well as their different parts (suspension , blocking ... etc).
  • This pad therefore differs from the previous example only in the shape of its front (40) and rear (41) shells.
  • the shell (40) has two wings (42) extending on either side of the front platform (1) and a part (43) forming a stop for the shoe.
  • Each wing (42) is provided on its external face with a projecting part (44) capable of receiving the front tightening strap (not shown in the drawing) of the pad.
  • the rear shell (41) also has two wings (45) extending on either side of the rear platform (2) and a part (46) forming a rear stop for the shoe.
  • each wing (45) is provided with a projecting part (47) allowing the passage of the rear tightening strap (not shown in the drawing).
  • the present invention is not limited to the sole embodiments shown here by way of non-limiting example, but embraces, on the contrary, all similar or equivalent embodiments; this is how, for example, the blocking and adjusting system of the length of the shoe could be reversed with respect to the platforms without departing from the scope of the invention.
