CA 02486774 2004-12-07
Field of the invention
This invention relates to inline skates in general but more specifically to a
antiskid device that covers the wheels of inline skates .
Description of the prior art
Ever since inline skates became popular and, to a certain extent, from the
time of the
older roller skates, the problem of using those same skates off track has been
problem. As is well known, afficionados of inline skating use them to go to
some messenger services even use inline skaters to deliver parcels. When comes
time to climb stairs or move around inside office buildings, use public
transit or roll
down steep hills, rolling wheels can be a hazard to both the users and
people. Several inventors have developped devices to cover the wheels of all
types of
roller skates. As usual, some inventors like things heavy, bulky and
impractical with
complex attachment means while others are a bit more practical and provide for
rather uncumbersome and easy to use skate wheel covers.
US patent 4,355,474 shows a flexible sole that can be attached by a skater to

CA 02486774 2004-12-07
roller skates to immobilize the wheels and provide a sole surface for
relatively normal
walking. The sole includes an elongated sheet with releasable mounting members
opposite ends. The mounting members may be attached to the skate in such a
manner that the sheet is drawn tautly over the wheels. The wheels are engaged
an upper surface of the sheet while a bottom surface functions as a relatively
stationary walking surface.
US patent 5,503,433 shows an accessory for a roller skate used for blocking
wheels of roller skates. This device comprises a plurality of elongated
members that
are made of non-slippery material and sized to snugly fit transversely between
two of
the wheels. These members are linked together, preferably by an elastic rope
is forming a closed loop. The device can be secured to the frame of the roller
whenever required by placing each member between two of the wheels to prevent
same from rotating. This device is very advantageous because it is inexpensive
very simple to install on a roller skate. It is also very light in weight and
thereby making it easy to carry.
US patent 5,836,425 shows a flexible molded block for immobilizing the wheels
of an
in-line roller blade skate which is portable and easy to use. The device is a
chock with a cavity in the center which cradles a wheel of an in-line skate
that it is
installed on. The device immobilizes the skate wheel and removes the stress
weight from the skate wheel, axle, and bearings by resting on a frame assembly
of a skate. The wheel chock cavity lip that is produced by using a in-line
roller blade

CA 02486774 2004-12-07
skate wheel when making the molded chock, keeps the chock on the skate,
preventing it from slipping or sliding off. The device is also small, light
weight and
easy to store when not in use.
US patent 4,413,842 shows a skate converter adapted to receive shoe skates
which upon fastening, permits the wearer to walk safely in shopping malls and
buildings where skate bearing persons are generally prohibited. The converter
includes a sole plate and two front and rearwardly spaced apart arcuate
sections all
of which are covered with a treadlike material to easily grip floors and rugs.
US patent 5,513,881 shows a skate guard having front and rear pieces with
slots for
receiving the front and rear portions of a skate runner. A center piece is
connected to the front and rear pieces, and it is formed of a stretchable
material which biases the front and rear pieces toward each other. The center
has a downwardly facing tread surface, and it is stiff enough to keep the
front and
rear pieces substantially longitudinally aligned with each other when the
device is not
on a skate runner. In a gap between the front and rear pieces, the center
piece has a
runner-protecting portion which is no higher than the bottom walls of the
receiving slots, and lies between two vertical longitudinal planes which
include the
sidewalls of the runner-receiving slots.
US patent 5,303,955 shows a roller wheel guard for in-line roller skates, is
formed of
an envelope-shaped body of flexible material such as woven nylon, open at the

CA 02486774 2004-12-07
with a rubbery bottom. The envelope-like body receives the series of aligned
and extends up to just below the boot of the skate. Side panels of the guard
have rear
extensions forming at least one strap to be wrapped tightly around the
wheel or the brake when the guard is installed. A further, vertical strap is
secured to the body and of an adjustable length so as to extend to the top of
the back
edge of the boot, with an attachment such as a clip for securing to the back
of the
boot, thus forming a handle when the guard is in place.
US patent 5,833,270 shows an in-line skate cover comprising a web, formed to
surround the wheels of the skate on a bottom, front and two side portions; and
a tread
on said bottom portion of said web, being provided with a high stiffness to
bowing between adjacent wheels of the skate. The in-line skate has a maximum
cross sectional dimension at a position above the wheels smaller than a cross
sectional dimension through an axis of the wheels, further comprising an
drawstring in a conduit formed on an upper edge of said web, for constricting
upper aperture of said web at said position above the wheels. An elastic strap
provided extending over a rear upper portion bf a hind wheel of the in-line
skate. The
cover has an open rear portion, and easily accommodates skates of differing
The cover is adapted to be held in wrapped condition around an anatomical body
portion, to provide protection andlor support.
US patent 6,481,724 shows an adapter comprising an ice-blade mounted in a
chassis. The blade-chassis is a plastic molding, which fits between the
support rails

CA 02486774 2004-12-07
of an in-line roller skate, and is clamped therebetween by the spindle-rods
that serve
as the spindles of the rollers. The ice-blade resides in a channel in the
the roof of the channel, and of the blade, being clear of, and below, the
spindle rods.
There is a copending application by this inventor for a variation on the
invention of
this instant application which features side panels configured and sized to
engage the side of the wheels up to or near the axle so as to securedly engage
antiskid device to the wheels.
Despite the numerous variations found in the prior art, the problem remains
that users
with long feet require long skate wheel covers which are cumbersome to carry
not in use. Some of the inventions provide for a mere blocking of the wheels
allowing the wheels to stil make contact with the ground. This can prove
ineffectual in
some circumstances when a user applies pressure on one wheel in particular
can occur in instances of climbing stairs when the back or the front wheel of
the skate
makes contact first. If a wheel is not perfectly blocked from rotating, an
accident can
Because of the drawbacks of the prior art, there is a need for an improved
wheel cover device and that includes this inventor's own copending application
is unfortunately not universally usable as not all makes or models of inline
have the same spacing between the wheels and the frame to support the wheels
that it can be too narrow to allow the side panels to fit on some models and
too wide

CA 02486774 2004-12-07
to provide enough of a frictional engagement on other models. That embodiment
work when configured for a specific make or model of inline skates where a
thickness for the side panels would fit.
In view of the foregoing disadvantages inherent in the known devices now
present in
the prior art, the present invention, which will be described subsequently in
detail, is to provide objects and advantages which are:
To provide for an antiskid device for inline skates which is easy to install
It is a second object of this invention to provide for an antiskid device for
inline skates
which can adapt to various wheel diameters as well as wheel spacing.
It is a third object of this invention to provide for an antiskid device for
inline skates
which is foldable onto itself in order to be more compact when not in use.
It is a fourth object of this invention to provide for an antiskid device for
inline skates
which covers the bottom part of all the wheels so that no contact between any
of the
wheels and the ground can occur.

CA 02486774 2004-12-07
To attain these ends, the present invention generally comprises an antiskid
which covers all the inline skate wheels and which can be folded onto itself
so as to
become half as long. In this way, it is much easier to conceal inside a pocket
or a

Fig. 1 Isometric view of the antiskid device installed on an inline skate (in
ghost lines).
Fig. 2 Side view of the antiskid device folded.
Fig. 3 Side view of the antiskid device unfolded.
An inline skate (10) has a pliable yet resillient antiskid device (12)
installed over its
wheels (14, 14', 14"). The antiskid device (12) consists of a pair of wheel
(16, 16'). Each receptacle (16, 16') only cover the bottom part of the wheels
(14, 14',
14"). A first receptacle (16) receives the front wheel (14) and one of the

CA 02486774 2004-12-07
wheels (14") and the other receptacle (16') receives the rear wheel (14') and
the other
middle wheel (14"). The anti skid device (12) consists mainly of a high
friction (hence
antiskid) elastomer means (18) cojoined to and covering a substantially large
part of
the exterior surFace which is a made of a synthetic resin to give it strength
and rigidity.
Two straps (28, 28') are fixedly attached to the antiskid device (12) with one
(28) being wrapped around the front wheel (14) and back down overlapping
itself and
going up in a "V" pattern to terminate at a point on the wheel assembly base
(15) of
the inline skate (10), where it is releasabfy attached by a releasable
means (29), and the other strap (28') doing a similar pattern but around the
wheel (14) and also releasably attached by a releasable attachment means
(29'). The
straps (28, 28') are releasably attached to the assembly base (15) by
attachment means (29, 29') which can be clipping means or preferably hook and
means, although a variety of suitable releasable attachment means can be
to strap around the inline skate (10) all within the scope of the invention.
The "V"
pattern creates a push-pull force which stabilizes the receptacles
(16, 16') so that they are not puNed forwardly, for the receptacle (16) at the
front of
the inline skate (10), or rearwardly, for the receptacle (16') at the rear of
the inline
skate (10).
The straps (28, 28') are themselves fixedly attached to the antiskid device
(12) in a
concave part (19) situated on the underside of the receptacles (16, 16').

CA 02486774 2004-12-07
(16, 16') come in pairs and two of them are needed for a 4 wheel inline skate
Each pair of wheel receptacles (16, 16') is linked to the other by way of a
hinge (26). The hinge (26) is used for folding each pair of receptacles (16,
16') by
rotating them together around the hinge (26) and mating them in clamshell
fashion to
procure a more compact size so as to facilitate carrying of the antiskid
device (12)
when not in use. Tabs (27) from one receptacle (16) interlock with the other
receptacle (16') in order to obtain proper alignment of the two receptacles
(16, 16')
as per Fig. 6 and in order to keep the antiskid device (12) in a closed
the straps (28) are used with one being folded inside the closed configuration
in the
empty space available and the other being wrapped around tightly so as to keep
antiskid device (12) in its closed configuration.
The pliable and resillient nature of the antiskid device (12) allows for
different wheel
(14) diameters to fit by flexing a tongue (30) which is an integral part of
the antiskid
device (12). Indeed, there are different wheel (14) diameters for different
inline skate
(10) models and sometimes, even on a single pair of inline skate (10).
As to the present state of technology, the preferred method of fabrication
consists in a
coninjection of plactic resin covered with a high friction elastomer material.
As to a further discussion of the manner of usage and operation of the present
invention, the same should be apparent from the above description.
Accordingly, no

CA 02486774 2004-12-07
further discussion relating to the manner of usage and operation will be
With respect to the above description then, it is to be realized that the
dimensional relationships for the parts of the invention, to include
variations in size,
materials, shape, form, function and manner of operation, assembly and use,
deemed readily apparent and obvious to one skilled in the art, and all
relationships to those illustrated in the drawings and described in the
specification are
intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles
of the
invention. Further, since numerous modifications and changes will readily
occur to
those skilled in the art, it is not desired to limit the invention to the
exact construction
and operation shown and described, and accordingly, all suitable modifications
equivalents may be resorted to, falling within the scope of the invention.
