Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present application is a National Stage Application of
PCT International Application No. PCT/FR2010/051535 (tiled on Jul.
21, 2010), under 35 USC. .sctn.371, which claims priority to French
Patent Application No. 0957853 (filed on Nov. 6, 2009), which are
each hereby incorporated by reference in their respective
entireties.
FIELD OF THE INVENTION
[0002] The present invention relates to an antiskid overshoe
intended to be secured reversibly to a shoe.
BACKGROUND OF THE INVENTION
[0003] Walking, let alone running, on slippery surfaces, is always
a perilous affair. To this end, various solutions have been put
forward to obviate the risk of slipping inadvertently which may
lead to the person falling over.
[0004] Among these solutions, shoes have been proposed that have a
sole defining a certain number of cleats, such as snow boots. This
type of shoe is relatively heavy and cumbersome, and is intended
for the sole purpose of walking on slippery surfaces.
[0005] A proposal has also been made to add cleat systems that use
thongs and other belts looping around the ankle and the top of the
foot. Here too, these systems are both relatively heavy and
relatively expensive.
[0006] In neither case is running conceivable.
[0007] There is a growing need for systems to be available that can
be added straightforwardly to a shoe, and are lighter in weight,
while endowing it with the requisite antiskid properties,
particularly on snow and ice.
[0008] Such is the object of this invention.
SUMMARY OF THE INVENTION
[0009] To this end, the invention relates to an antiskid overshoe
suitable for being reversibly secured to a shoe, whatever type of
shoe is involved.
[0010] This antiskid overshoe consists of a net made of a textile
material, and in this instance, consists of cords produced by
knitting, said cords in turn being assembled together by knitting,
so as to define the meshes of the net suitable for forming
cleats.
[0011] Additionally, both ends of the net are encapsulated in a
strap, each defining a closed loop.
[0012] Lastly, it includes an elastic cord, passing through the
meshes defined at the two side edges of the net, as well as through
the two loops defined by the straps.
[0013] Thus, because of the elastic nature of the cord, the
resulting inventive shoe is easily positioned on a shoe, and the
cleats defined by the meshes of the net, constitute effective means
for countering the risks of slipping,
[0014] Incidentally, because of the nature of the net and the
particular lightness thereof, neither walking nor even running is
affected by this overshoe.
[0015] In accordance with one advantageous feature of the
invention, the overshoe is also provided with an additional loop
suitable for stretching over the top of the user's foot after the
overshoe is put in place, and optimising the actual securement of
the overshoe on the user's shoe.
[0016] To advantage, the net is made of polyester or polyamide (or
PP/PE), possibly coated with polyurethane and generally with
elastomer, suitable for optimising the antiskid characteristics of
the overshoe.
[0017] Additionally, the net may be provided with clasps or clips,
positioned either at the junction of the cords defining the meshes
of the net, or at any point on said cords, in the interests of
optimising the anti-slip characteristics on hard surfaces, such as
ice or black ice. These clasps are made of metal or plastic, or
even thermoplastic material.
BRIEF DESCRIPTION OF THE DRAWINGS
[0018] The manner in which the invention may be implemented, and
the resulting advantages, will become clearer from the following
embodiment example, given for information purposes and
non-restrictively, supported by the appended figures.
[0019] FIG. 1 illustrates a diagrammatic perspective view of the
overshoe in accordance with the invention, set in place on a
shoe.
[0020] FIG. 2 illustrate a diagrammatic view of the elastic cord
employed in the inventive shoe provided with its two straps, front
and rear respectively.
[0021] FIG. 3 illustrates a diagrammatic view showing the net
constituting the overshoe, shown fiat, and provided with its front
and rear straps.
DETAILED DESCRIPTION OF EMBODIMENTS
[0022] In FIG. 1 the antiskid overshoe in accordance with the
invention has thus been illustrated set in place on a shoe. It will
be noted that the shoe in this instance is a totally conventional
shoe, in this instance a sports shoe, exactly as permitted by the
inventive overshoe.
[0023] In accordance with the invention, this overshoe basically
consists of a net 1 made of a textile material and defining a
certain number of meshes 10, the meshes 10 being intended to form
cleats, suitable for providing the requisite adhesion on a slippery
surface and in particular on snow.
[0024] Thus, the meshes 10 form so many projections, the typical
height of which relative to the sole of the shoe is roughly between
3 and 8 turn.
[0025] In accordance with the invention, this net 1 is formed by
knitting cords 16, in turn obtained by knitting.
[0026] In accordance with the invention, the operation of knitting
the cords 16, and the net 1 itself, is performed simultaneously,
for example, on knitting machines of the MULLER type or the like,
and to be more specific on a GWM double bed square section knitting
machine or on a RD3/MT3 single bed round section knitting
machine.
[0027] The cords 16 are produced, as already stated, by knitting
and each comprise a plurality of strands, for example, from one to
ten. The required diameter of each cord 16, and therefore,
consequently the height of the cleats, is obtained by knitting and
tightening the strands to each other.
[0028] These cords 16 are made of polyester or polyamide. A
combination is sought of high mechanical strength, good adhesion
properties, and to advantage a certain abrasion resistance.
[0029] During the knitting operation, meshes 10 are formed, of
substantially standardised dimensions, for example 40.times.40 mm
which, when the net in question is set in place on the shoe, have a
square or diamond shape.
[0030] The front 12 and rear 11 ends respectively of the net are
each encapsulated in a front 3 and rear 4 strap respectively, the
straps 3, 4 being sewn edge to edge to prevent delamination of the
net 1, in other words to ensure the stability of the net 1 over
time.
[0031] These straps 3, 4 are, for example, made of polypropylene or
polyester and each define a loop 7 and 6 respectively, for passing
through an elastic cord 2, which continues its way in the meshes 14
and 15 respectively on both side edges of the net 1.
[0032] In so doing, the elastic cord 2, because of its elasticity,
secures the overshoe to the shoe.
[0033] In the interests of optimising this securement, and in
particular when the overshoe is intended to be set in place on a
sports shoe for sport on snow or mud for example, the securement is
optimised by means of a strap or loop 8, one end of which is
secured to one of the side strands of the elastic cord 2, and the
other end of which is wound around the other side strand of the
cord 2, and is pulled down onto the strap and secured reversibly
thereto, for example, by means of a loop and hook system 9 (such as
Velcro.RTM. for example).
[0034] In accordance with one advantageous feature of the
invention, the net is also provided with clasps or clips 13,
arranged, for example, in junction zones of the cords 16 forming
the meshes 10, this location not, however, being mandatory. These
clasps or clips 13, of metal, for example (stainless steel or
galvanised steel), are intended to partially penetrate into a hard
material, such as ice, in order to optimise the antiskid properties
of the overshoe.
[0035] Lastly, and in order to facilitate setting the overshoe in
place on the shoe, the rear strap 4 is provided with a loop-forming
tab 5, allowing one of the user's fingers to pass through so as to
promote the insertion of the overshoe on the shoe.
[0036] It is easily understood that because of the very
considerable lightness of the overshoe, it does not affect walking
or running, something which was not achievable with known prior art
devices.
[0037] Incidentally, the cleats defined by the meshes of the net
promote the adhesion of the shoe thus covered with the overshoe,
and particularly on snow, with no need to provide specific
components or devices as described in the prior art such as
detachable cleats.
[0038] Lastly, it is easy to understand how extremely
straightforward it is to set the inventive overshoe in place, since
the shoe has merely to be inserted into the rear zone of the
overshoe, defining in the zone where the rear strap engages with
the net, a housing provided to this end, and by means of the
elastic cords and the tab 5, the rear part of the overshoe is
positioned correctly on the shoe.
[0039] Although embodiments have been described herein, it should
be understood that numerous other modifications and embodiments can
be devised by those skilled in the art that will fall within the
spirit and scope of the principles of this disclosure. More
particularly, various variations and modifications are possible in
the component parts and/or arrangements of the subject combination
arrangement within the scope of the disclosure, the drawings and
the appended claims. In addition to variations and modifications in
the component parts and/or arrangements, alternative uses will also
be apparent to those skilled in the art.
