Skate with in-line wheels

A skate with in-line wheels, having a first front body, for supporting and locking the front part of the foot, and a second rear body, for supporting and locking at least the heel, the bodies having a first frame and a second frame for supporting a plurality of wheels. The first and second bodies and the first and second supporting frames are rotatably associated to each other to allow better transmission of lateral forces during sports practice.

BACKGROUND OF THE INVENTION 
The present invention relates to a skate with in-line wheels. 
Conventional in-line roller skates comprise a shoe comprising a quarter 
articulated to a shell, which has a rigid sole that is associated, in a 
downward region, with a usually U-shaped support or frame between the 
wings whereof wheels are pivoted. The wheels are thus arranged in line 
with respect to each other. 
These conventional skates have some drawbacks: when skating, and 
particularly during thrusting, difficulties are in fact encountered in 
optimally and completely transferring the thrust imparted by the user, 
thus decreasing the effectiveness of the thrust and the comfort for the 
foot. 
The user in fact tends to transmit forces mainly at the region of the foot 
sole lying below the metatarsal region, but the rigidity of the support 
and of the sole of the shoe instead force him, during thrusting, to fully 
rest the foot sole on the shoe sole, so that the transmitted forces are 
divided between the wheels that are pivoted at the front and the wheels 
that are pivoted at the rear, with a consequent loss of effectiveness in 
thrusting. 
U.S. patent application Ser. No. 08/451,621 filed May 26, 1995 discloses a 
roller skate with improved fit that is constituted by a first front body, 
for resting and locking the front part of the foot, and by a second rear 
body, for resting and locking at least the heel. 
The first body and the second body are transversely rotationally associated 
to each other in a region that lies approximately above the pre-arch 
portion of the foot and in the interspace that lies between a first 
supporting frame and a second supporting frame for one or more wheels 
associated with said frames in a downward region. 
Although this solution allows articulation of the shoe, it nonetheless has 
drawbacks: in fact, the rotation, stability, and overall rigidity of the 
skate are correlated only to the articulation point, which is not 
sufficient for their optimization. 
These drawbacks are increased by the fact that during sports practice the 
skate is subjected, during periods of maximum thrusting, to continuous and 
often violent lateral stresses, as can occur for example when skating 
along a curve or during slalom skating or in particular during so-called 
"side-slip" braking. 
The articulation point must therefore absorb all these applied stresses and 
at the same time ensure the rotation and rigidity of the shoe and good 
stability of the foot; however, these conditions cannot all be met 
simultaneously. 
During skating, the foot is in fact subjected to considerable vibrations 
and lateral stresses that accordingly decrease the user's sensitivity in 
utilization and the lateral stability of the implement. 
The user is also forced to increase the force in order to achieve optimum 
stability of the skate, with consequent tiring during exercise and 
reduction in comfort throughout sports practice. 
SUMMARY OF THE INVENTION 
A principal aim of the present invention is therefore to solve the 
described problems, eliminating the drawbacks of the cited prior art by 
providing a skate that allows the user to transmit forces in an optimum 
manner during thrusting, at the same time allowing a correct anatomical 
movement of the foot. 
Within the scope of this aim, an important object is to provide a skate 
that allows to transmit efforts during thrusting selectively only at the 
front part of the foot, at the same time allowing to achieve optimum 
lateral support of the skate during all phases of sports practice. 
Another object is to provide a skate having increased operating sensitivity 
and comfort, particularly during periods of maximum thrusting. 
Another important object is to provide a skate that allows to achieve the 
necessary assurances of stability for the user throughout sports practice. 
Another object is to provide a skate that can be produced at low costs and 
with conventional machines and equipment. 
This aim, these objects, and others that will become apparent hereinafter 
are achieved by a skate with in-line wheels characterized in that it 
comprises a first member and a second member, at least one of said members 
being adapted to support a plurality of in-line wheels, said first member 
being rotatably associated with said second member.

DESCRIPTION OF THE PREFERRED EMBODIMENTS 
With reference to the above figures, the reference numeral 1 designates a 
skate that is constituted by a first front body 2 that forms the tip 3 of 
a shell 4 that surrounds the front region of the foot and locks it, and 
has an upper longitudinal slot 5. 
A first supporting frame 6 is associated below the first body 2 in the 
particular illustrated embodiment; said frame is substantially U-shaped, 
and at least two first in-line wheels 8 are rotatably associated between 
the first wings 7a and 7b of said frame 6. 
The skate comprises a second rear body 9 that is constituted by a heel cup 
10 that wraps around part of the leg and of the foot up to the vicinity of 
the foot flexing region; a cuff 12 that wraps around the tibial region is 
optionally but not necessarily pivoted laterally to said heel cup at an 
adapted pair of studs 11. 
The second rear body 9 also has a longitudinal front opening 13 for the 
insertion of, for example, a soft innerboot or directly of the user's 
foot; the foot is secured by adapted levers 14 that transversely connect 
the flaps 15a and 15b of the second rear body 9. 
An adapted brake 16 can be associated at the cuff 12 and has a pad 17 that 
interacts with the ground when said cuff is rotated backwards. 
A second supporting frame 18 is associated below the heel region of the 
second body 9; in a transverse cross-section said frame is U-shaped, and 
second in-line wheels 20 are rotatably associated between the second wings 
19a and 19b of said second frame. 
The first body and the second body, as well as the first and second 
supporting frames, are transversely and rotatably associated together, and 
guiding and sliding means are provided on said first and second frames. 
Rotary coupling is allowed by the presence of a plurality of first tabs 21 
that protrude downward and axially with respect to the first body 2, both 
in the interspace lying between the two first wings 7a and 7b of the first 
frame 6 and outside the frame, and by a plurality of second tabs 22, which 
protrude downward and axially at the end of the second body 2 that is 
directed towards the first body 6, both in the interspace lying between 
the second wings 19a and 19b and in a region lying outside them. 
The first and second tabs therefore have a comb-shaped configuration and 
can be arranged adjacent to each other when the first body 2 is joined 
axially to the second body 9. 
Third tabs 23 protrude, at the end of the second body 9 that has the second 
tabs 22, below the second wings 19a and 19b and outside them. 
Adapted first holes 27, second hole 28, third holes 29, fourth holes 30, 
and fifth holes 31 are formed, along the same axis 26, on the first, 
second, and third tabs, as well as on the first ends 24 and on the second 
ends 25 of the first frame 6 and of the second frame 18; all of said holes 
form a seat for a first pivot 32. 
Said first pivot 32 has a head 33 that abuts against one of the third tabs 
23 and a stem that is internally threaded, at the other end, for coupling 
to a complementarily threaded first screw 34 that abuts at the other third 
tab 23. 
The skate furthermore comprises guiding and sliding means provided on the 
first and on the second frames; said means are constituted by a second 
pivot 35 that passes at two sixth holes 36 formed at the ends of the first 
wings 7a and 7b that partially laterally wrap around the corresponding 
ends of the second wings 19a and 19b of the second frame 18. 
The sliding of the first and second ends of the first and second frames is 
allowed by the presence of two adapted slots 37 that are formed on the 
ends of the second wings 19a and 19b; said slots have a curved shape that 
allows the second body 9 to rise from the ground during thrusting, when 
the first wheels 8 are in contact with said ground. 
The two slots 37 are of course formed on the second wings 19a and 19b at 
the sixth holes 36 provided on the first wings 7a and 7b of the first 
frame 6. 
A seventh hole 38 and an eighth hole 39 are advantageously formed, 
respectively on the first wings and on the second wings of the first and 
second frames, so that they are adjacent to the sixth holes 36 and to the 
pair of slots 37; said holes 38 and 39 have the same axis when both the 
first wheels 8 and the second wheels 20 interact with the ground and 
therefore when the skate is in a horizontal condition. 
In this condition it is thus possible, by inserting a pin or pivot in the 
seventh hole 38 and in the eighth hole 39, to lock the sliding of the 
first and second frames, which therefore cannot rotate at the axis 26. 
The first pivot 32 and the second pivot 35 of course act at the interspace 
between a first wheel 8 and a second wheel 20 that are adjacent to each 
other. 
Use of the invention is thus as follows: once the first and second frames 
and the first and second bodies have been associated one another by means 
of the first pivot 32 and the second pivot 35, the skater can achieve 
optimum lateral thrusting, since the second body can rotate, rising from 
the ground, allowing to concentrate the forces on the first wheels 8, 
while lateral forces can still be transmitted by virtue of the partial 
overlap of the first and second wings of the first and second frames; the 
sliding of the second pivot 35 in the slot 37 allows to achieve guided 
lifting of the second frame 18 with respect to the first frame 6. 
It has thus been observed that the invention has achieved the intended aim 
and objects, a skate having been obtained which allows the user to 
transmit forces in an optimum manner during thrusting, at the same time 
allowing a correct anatomical movement of the foot; during thrusting, said 
forces can be selectively concentrated exclusively at the front part of 
the foot, at the same time allowing to achieve optimum lateral containment 
of the skate throughout sports practice. 
The invention is of course susceptible of numerous modifications and 
variations, all of which are within the scope of the same inventive 
concept. 
Thus, for example, FIG. 7 illustrates a second embodiment, in which the 
reference numeral 101 designates a skate constituted by a shell 102 with 
which a quarter, not shown, can be articulated at the malleolar region by 
means of appropriate studs or rivets. 
The shell 102 is constituted by a first body 109a, which is U-shaped in 
transverse cross-section and is constituted by a first flat support 131a, 
from which two lateral shoulders protrude upwardly; said shoulders allow 
to contain the front part of a shoe 130 or the foot at the tip region 105. 
The first body 109a has a first strap 132a the ends whereof are associable 
with the two lateral shoulders; said first strap 132a allows to secure the 
shoe 130 or the foot. 
The shell 102 has a second body 109b, which is constituted by a second flat 
support 131b, from which a heel cup protrudes perimetrically and upwardly 
and is adapted to contain at least the heel region 115 of the shoe 130. 
The second body 109b has a second strap 132b the ends whereof are laterally 
associated with the heel cup; said strap provides securing at the foot 
instep region 133. 
The first and second bodies 109a and 109b can be transversely and rotatably 
associated, at their ends which can be placed adjacent to each other, by 
means of a hinge-like articulation that comprises an adapted screw or a 
connecting pivot 134. 
A first frame 110a and a second frame 110b are associated respectively with 
the first body 109a and with the second body 109b; both frames are 
U-shaped, and at least two first and second wheels 111a and 111b, 114a and 
114b are respectively pivoted between the first and second wings, which 
protrude downwardly, of said frames. 
The center distance of the second wings of the second frame 110b is smaller 
than the center distance of the first wings of the first frame 110a, so as 
to allow the partial insertion and adjacent arrangement of the second 
wings with respect to the first wings on an approximately parallel plane. 
The first frame 110a and the second frame 110b have means 116 for mutual 
guiding and sliding. 
Said means 116 are constituted by a pin 117 that is associated and blended, 
at right angles, with the tips of the first wings of the first frame 110a 
in a region that is intermediate between two of said first and second 
wheels that are adjacent to each other; the first pin 117 slides at a slot 
118 that is formed on the second wings of the second frame 110b that are 
arranged adjacent to the first wings of the first frame 110a. 
The slot 118 is arc-shaped, with its concavity directed at the tip region 
105. 
This solution, too, allows to achieve the intended aim and objects. 
With reference to FIGS. 8-11, the reference numeral 201 designates a skate 
constituted by a shell 202, to which it is possible to articulate a 
quarter 203 associated at the malleolar region by means of appropriate 
studs or rivets. 
The shell 202 is formed monolithically, is preferably made of plastics, and 
has a lower region that forms a sole 204. 
A first frame 206 is associated below the sole 204 in the metatarsal region 
205 and is U-shaped in transverse cross-section; at least one pair of 
first wheels 208a and 208b is pivoted between the first wings 207a and 
207b of said first frame, which protrude towards the ground. 
The first frame 206 has a first base 209 for connecting the first wings 
207a and 207b; said base is perforated, so as to form a seat for the 
positioning of a first tab 210 in said base, and said first tab protrudes 
below the sole 204 in the metatarsal region 205. 
A pair of second tabs 211a and 211b also protrudes below the sole 204 so as 
to lie approximately parallel to the first tab; said second tabs are 
arranged externally with respect to the first wings 207a and 207b of the 
first frame. 
A second frame 213 is associated below the sole 204, approximately at the 
heel region 212; said second frame, too, is U-shaped in transverse 
cross-section, forming a second base 214 for anchoring to the sole 204, 
two second wings 215a and 215b protruding from said second base, at least 
one pair of second wheels 216a and 216b being pivoted between said second 
wings. 
An adapted brake 217 is advantageously associable at the quarter 203 and 
has a pad 218 that interacts with the ground when said cuff is rotated 
backwards. 
A first hole 219 and second holes 220a, 220b are formed, along the same 
axis, respectively at the first tab 210 and at the second tabs 211a and 
211b; said holes accommodate a pivot 221 that also passes at adapted third 
holes 222a and 222b formed at the first wings 207a and 207b of the first 
frame 206 proximate to the first base 209. 
At least one means adapted to limit the oscillation of the second frame 213 
and/or of the shell 202 is interposed between the lower surface of the 
sole 204 and the first base 209; the means is constituted by a flexible 
insert 223 that is preferably rectangular in plan view and has a hole 
which allows the insertion of the first tab 210. 
The second frame 213 has two third tabs 224a and 224b that protrude from 
the second wings 215a and 215b towards the first frame 206 and have such a 
length and size as to be arranged laterally adjacent outside the second 
tabs 211a and 211b that protrude from the sole 204 and the ends of the 
first wings 207a and 207b of the first frame that are adjacent to the 
first base 209. 
Advantageously, the profiles of the first wings and of the pair of third 
tabs have narrower portions that allow to contain the length of the pivot 
221. 
The two third tabs 224a and 224b are slightly curved towards the sole 204, 
and are perforated at the tip in order to be pivoted to the pivot 221. 
The operation of the invention is as follows: during thrusting, which is 
shown schematically in FIG. 10, the skater can lift the second frame 213 
by the presence of the pair of third tabs 224a and 224b, localizing forces 
exclusively at the first frame 206 and therefore at the first wheels 208a 
and 208b. 
Furthermore, use of the particular configuration of the second frame and of 
the pair of third tabs allows to shift the rotation point at the axis of 
the pivot 221 directly below the sole of the shell. 
It has been observed that the invention has achieved the intended aim and 
objects, since it is adapted to transmit forces in an optimum manner 
during thrusting and at the same time allows a correct anatomical movement 
of the foot. 
The presence of the pair of third tabs in fact allows, while having a 
monolithic shell, to lift the second frame, so that the user can transmit 
forces, during thrusting, selectively only at the front part of the foot, 
at the same time allowing to achieve optimum lateral containment and 
rigidity of the entire skate throughout sports practice. 
With reference to FIGS. 12-15, the reference numeral 301 designates a skate 
constituted by a shell 302, whereto it is possible to articulate a quarter 
303 associated at the malleolar region by means of appropriate studs or 
rivets. 
The shell 302 is formed monolithically, is preferably made of plastics, and 
has a lower region that forms a sole 304. 
A first frame 306 is associated below the sole 304 in the metatarsal region 
305 and is U-shaped in transverse cross-section; at least one pair of 
first wheels 308a and 308b is pivoted between the first wings 307a and 
307b of said first frame, which protrude towards the ground. 
The first frame 306 has a first base 309 for interconnecting the first 
wings 307a and 307b; said base is perforated, so as to form a seat for the 
positioning of a first tab 310 in said base, and said first tab protrudes 
below the sole 304 in the metatarsal region 305. 
A pair of second tabs 311a and 311b also protrudes below the sole 304 so as 
to lie approximately parallel to the first tab; said second tabs are 
arranged externally with respect to the first wings 307a and 307b of the 
first frame. 
A second frame 313 is also associated below the sole 304, approximately at 
the heel region 312; said second frame, too, is U-shaped in transverse 
cross-section, forming a second base 314 for anchoring to the sole 304, 
two second wings 315 protruding from said second base; at least one pair 
of second wheels 316a and 316b is pivoted between said second wings. 
An adapted brake 317 is advantageously associable at the quarter 303 and 
has a pad 318 which interacts with the ground when said cuff is rotated 
backwards. 
A first hole 319 and second holes 320a, 320b are formed, along the same 
axis, respectively at the first tab 310 and at the second tabs 311a and 
311b; said holes accommodate a pivot 21 that also passes at adapted third 
holes 322a and 322b formed at the first wings 307a and 307b of the first 
frame 306 proximate to the first base 309. 
At least one means adapted to limit the oscillation of the second frame 313 
and/or of the shell 302 is interposed between the lower surface of the 
sole 304 and the first base 309; said means is constituted by a flexible 
insert 323 which is preferably rectangular in plan view and has a hole 
that allows the insertion of the first tab 310. 
The skate also has a rigid connecting element 324 that is adapted to 
connect the first frame, the second frame, and the shell to one another; 
said connecting element is constituted by two profiles that are L-shaped 
and therefore have respective third wings 325 and fourth wings 326; the 
tips of said wings are pivoted respectively at the pivot 321 and at the 
pivoting axis of the second wheel 316a of the second frame 313 that is 
adjacent to the first frame 306, which is arranged in front. 
Advantageously, the profiles constituting the connecting element are 
arranged outside the first and second frames. 
It is also possible to advantageously provide narrower portions, adapted to 
contain the extension of the pivot 321, at the first frame and at the 
third wings 325. 
The third wings 325 and the fourth wings 326 are thus arranged 
approximately parallel to the first wings 307a and 307b and to the second 
wings 315 of the respective first and second frames, so as to allow mutual 
sliding. 
The elbow of the connecting element 324, which joins the third wing 325 and 
the fourth wing 326, is furthermore arranged approximately at the first 
wheel 308b of the first frame 306 that is adjacent to the second frame 
313, where each profile is pivoted at the first wheel 308b and therefore 
between the first wings 307a and 307b of the first frame 306. 
Additional means for limiting the oscillation of the second frame and/or of 
the shell are constituted by at least one lug 327 that protrudes at least 
from one of the first wings 307a and 307b in a region lying to the rear of 
the perimetric edge of the third wings 325 that is directed towards the 
heel region 312; said lug is arranged so as to abut against the perimetric 
edge of the third wings 325 in the inactive condition in which all the 
wheels rest on the ground. 
The operation of the invention is as follows: during thrusting, which is 
shown schematically in FIG. 14, the skater can lift the second frame 313 
by the presence of the connecting element 324, localizing forces 
exclusively at the first frame 306 and therefore at the first wheels 308a 
and 308b. 
Furthermore, use of the L-shaped profile for the connecting element allows 
to shift the rotation point at the axis of the first wheel of the first 
frame and therefore in a point that is very close to the ground and is 
anatomically favorable for the rotation of the foot during thrusting. 
It has been observed that the invention has achieved the intended aim and 
objects, since it is adapted to transmit forces in an optimum manner 
during thrusting and at the same time allows a correct anatomical movement 
of the foot. 
The connecting element in fact allows, while having a monolithic shell, to 
lift the second frame, so that the user can transmit forces, during 
thrusting, selectively only at the front part of the foot, at the same 
time allowing to achieve optimum lateral containment and rigidity of the 
entire skate throughout sports practice. 
With reference to FIGS. 16-17, the reference numeral 401 designates a skate 
constituted by a shell 402, to which it is possible to articulate a 
quarter 403 that is associated at the malleolar region by means of 
appropriate studs or rivets. 
The shell 402 is formed monolithically, is preferably made of plastics, and 
has a lower region that forms a sole 404. 
The shell 402 has, proximate to the tip region 405, an articulation 406 
constituted by a slit that is formed on an approximately transverse plane 
starting from the vicinity of the sole 404; said slit forms a first flap 
407a and a second lap 407b having such a shape as to allow their partial 
overlap, even in the inactive condition, and particularly the insertion of 
the first flap 407a in the second flap 407b. 
During sports practice, while thrusting and flexing the foot, the mutual 
overlap of the first and second flaps 407a and 407b increases, thus 
facilitating the flexing of the foot. 
The first and second flaps 407a and 407b have, proximate to the sole 404, a 
curved shape that is adapted to form a circular recess 408; said recess 
408 allows to improve the flexibility, and therefore the overlap, of said 
first and second flaps 407a and 407b. 
The articulation 406 forms, for the shell 402, a first front body 409a that 
is arranged at the tip region 405 starting from the flap 407a; said first 
body 409a allows to contain and secure the front part of the foot. 
The articulation 406 also forms a second body 409b which, starting from the 
second flap 407b, allows to contain and secure the rear part of the user's 
foot. 
A first frame 410a is associated in a downward region with the first body 
409a; the transverse cross-section of said frame is U-shaped, and at least 
one pair of first wheels 411a and 411b is pivoted between the first wings 
of said frame, which protrude downwards. 
The first frame 410a is constituted by a first flat base 412a for 
connecting the first wings, which is connected below the sole 404 through 
the interposition of adapted connecting means, such as rivets, that are 
accommodated in a complementarily shaped first seat 413a that is formed on 
the sole 404 that lies below the first body 409a. 
The first wings of the first frame 410a protrude in the opposite direction 
with respect to the tip region 405. 
A second frame 410b is also associated, in a downward region, with the 
second body 409b in the region of the heel 415; said second frame is 
U-shaped in a transverse cross-section, and at least one second pair of 
wheels 414a and 414b is pivoted between its second wings, which protrude 
below a second connecting base 412b. 
The second base 412b is connected to the sole 404 through the interposition 
of adapted connecting means, such as rivets or couplings inserted at a 
complementarily shaped second seat 413b formed on the sole 404 at the heel 
region 415. 
The second base 412b is preferably narrower than the first base 412a, so as 
to allow the partial insertion and adjacent arrangement, along 
approximately parallel planes, of the second wings of the second frame 
410b with respect to the first wings of the first frame 410a. 
The first and second frames 410a and 410b have means 416 for their mutual 
guiding and sliding. 
Said means 416 are constituted by a pivot 417 that is associated and 
blended at right angles with respect to the tins of the first wings of the 
first frame 410a in a region that is intermediate between two of said 
first and second wheels that are adjacent to each other; the first pivot 
417 slides at a slot 418 that is formed on the second wings of the second 
frame 410b that are adjacent to the first wings of the first frame 410a. 
The slot 418 has a curved shape, the concavity whereof is directed at the 
tip region 405. 
The pivot 417 can be arranged at the upper end of the slot 418 if the pair 
of first wheels 411a and 411b and the pair of second wheels 414a and 414b 
rest on the ground, generally designated by the reference numeral 419; 
during thrusting, instead, as shown in FIG. 17, the foot flexes, and the 
second body 409b and therefore the second frame 410b rise, forcing the 
sliding of the pivot 417 inside the slot 418 until it reaches the lower 
end of said slot, which constitutes a stroke limiter. 
Advantageously, the first frame 410a and the second frame 410b have, on 
each one of said first and second wings, respectively a first hole 420a 
and a second hole 420b, which have the same axis in the inactive 
condition, are arranged above the means 416, and allow the insertion of a 
pivot or screw that allows to lock the skate 401 in the horizontal 
condition, so that the pair of first and second wheels 411a and 411b, 414a 
and 414b rest on the ground 419 so as to prevent, according to the user's 
requirements, the rotation of the skate 401. 
A conventional brake 421 is associated with the skate 401 to the rear. 
The operation of the skate is as follows: during thrusting, the flexing of 
the foot and the rise of the rear part thereof is allowed by the 
articulation 406 formed on the shell 402, which is provided by the mutual 
overlap of the first and second flaps 407a and 407b of the first and 
second bodies 409a and 409b. 
The connection of the second body 409b to the second frame 410b allows the 
latter to rise with respect to the ground 419, whereas the sliding of the 
pivot 417 in the slot 418 allows guided lifting. 
It has been observed that the invention has achieved the intended aim and 
objects, said invention being adapted to transmit forces in an optimum 
manner during thrusting, at the same time allowing a correct anatomical 
movement of the foot; the articulation 406 provided on the shell 402 in 
fact allows to flex the foot naturally, producing more thrust for an equal 
physical effort. 
The sliding and guiding means 416 allow to lift the second frame 410b so 
that the user can thus transmit forces, during thrusting, selectively and 
exclusively at the front region of the foot; at the same time, said means 
416 allow to achieve optimum lateral containment and rigidity of the 
entire skate throughout sports practice. 
FIG. 18 illustrates still a further embodiment, in which the numeral 501 
designates a skate constituted by a shell 502. 
The shell 502 is constituted by a first front body 509a, which is arranged 
proximate to the toe region 505 and adapted to surround it, and by a 
separate second rear body 509b, to which a quarter 503 can be articulated. 
The first and second bodies 509a and 509b have, respectively, a first sole 
504a and a second sole 504b which are transversely and rotatably 
associated with each other, at their ends that can be arranged mutually 
adjacent, by means of a hinge-like articulation that comprises an adapted 
transverse connecting screw or pivot 534. 
The first and second bodies 509a and 509b have, respectively, a first flap 
507a and a second flap 507b, which have such a shape as to allow their 
partial overlap, even in the inactive condition, and particularly the 
insertion of the first flap 507a in the second flap 507b. 
A frame 510 is associated below the first body 509a and has a U-shaped 
transverse cross-section; at least one pair of first and second wheels, 
designated respectively by the reference numerals 511a and 511b, 514a and 
514b, is pivoted between the first wings of said frame, which protrude 
downwardly. 
The frame 510 is connected, in a downward region, to the first sole 504a of 
the first body 509a through the interposition of adapted connecting means, 
such as rivets or couplings, that are accommodated in a complementarily 
shaped seat 513 formed on said first sole 504a. 
This solution, too, allows to achieve the intended aim and objects, since 
the second body can rise from the frame during thrusting, which becomes 
localized, i.e., entrusted to the front region. 
The materials and the dimensions constituting the individual components of 
the skate according to the invention may be the most appropriate according 
to the specific requirements.
