Description
FIELD OF THE INVENTION
[0001] The present invention relates to the field of weighted
footwear, and in particular, relates to a weight system for use on
a skate.
BACKGROUND OF THE INVENTION
[0002] Exercising weights for various types of footwear, and in
particular, various types of skates, have been previously
described. For example, various weighted skate devices have been
described in Canadian patent publication Nos. 2088617 and 2217759.
Further, additional weighted footwear has also been described in
U.S. Pat. Nos. 3,582,067, 3,901,524, and more recently, US Patent
Publication No. 2004/0259666. These documents all provide systems
and devices for attaching weights to the legs or footwear worn by
an athlete. This use of athletic training devices which are capable
of having or including additional weights, attached to either a
participant or their athletic equipment during a training session,
is well known. These devices are commonly used during practice
sessions as the athletes simulate the movements and activities they
will employ during competition. By practicing with additional
weight, an athlete develops strength, speed and endurance as their
body works to overcome the additional weight. In addition,
practicing with these devices creates an added sense of quickness
and confidence in an athlete when the weight is removed during a
game situation. As such, these devices assist in developing the
athlete's strength, stamina, speed, or overall conditioning.
[0003] With particular reference to footwear, and skates in
particular, the purpose of mounting additional weights on ice
skates is to improve the performance of skaters, either
professional or ordinary skaters, who wish to improve their
performances while skating. Prior art devices include ankle weights
to be wrapped around the ankles of the athlete, weights adapted to
be strapped on to, or attached to, a skate, or flexible weighted
tapes or bindings that can be wrapped around various portions of
the skate.
[0004] However, traditional ankle weights are not particularly well
suited for use on a skate since they tend to be held too far up the
leg since the boot of the skate interferes with a lower location of
the ankle weight.
[0005] Further, the various weights used and described in the prior
art devices, for attachment to the skate, all typically locate the
weight at a location away from the ankle and/or away from the point
of rotation of the foot in the normal movement of the foot. This
leads to excessive weight being located in a position where it does
not assist in developing leg strength, but requires overuse of the
ankle and foot muscles and tendons in order to move and/or
compensate for the poorly distributed weight. This excessive
weighting can lead to strained muscles, tendinitis, or other
injuries related to the foot or ankle. Further, the poorly
positioned weighting of the skate can affect the skater's balance,
skating motion, or affect the skater's normal agility or
flexibility.
[0006] As such, to overcome these difficulties, it would be
advantageous to provide a weight system for a foot or footwear, and
in particular, a skate, that could be better positioned, with
respect to the user's ankle position.
SUMMARY OF THE INVENTION
[0007] Accordingly, it is a principal advantage of the present
invention to provide a weight to a skate in order to require a
greater performance from the legs of the skaters within a shorter
period of time.
[0008] It is a further advantage of the present invention to
provide a system wherein the weights are securely attached to the
skates in order to ensure that they will not move during any
regular exercise of the skater.
[0009] A still further advantage of the present invention is to
provide a securing means which will make the device easily
installed or removed from the ice skates so that a skater may
install or remove it quickly before a hockey game, an artistic
performance or a mere exercise practice.
[0010] It is a still further advantage of the present invention to
provide a weight system wherein the weights are located in a
position that will not unduly interfere with the skater's nature
balance, flexibility or skating motion.
[0011] A yet still further advantage of the present invention is to
provide a weight system wherein the weights are located in a
position wherein excessive strain on the muscles and tendons of the
ankle joint is eliminated or otherwise ameliorated.
[0012] An even further advantage of the present invention is to
provide a weight system wherein weights can be easily added or
removed from the system, and wherein the weight on each side of the
ankle can be adjusted or balanced.
[0013] The advantages set out hereinabove, as well as other objects
and goals inherent thereto, are at least partially or fully
provided by the foot weight system of the present invention, as set
out herein below.
[0014] Accordingly, in one aspect, the present invention provides a
foot weight device for adding weight to the foot of a user,
comprising a retaining system for attaching the foot weight device
to the foot or footwear of a user, one or a plurality of preferably
removable weights for use in the foot weight device, and one or a
plurality of weight receiving pockets, attached to said retaining
system, for receiving and holding said weights, wherein said weight
receiving pockets are positioned on said retaining system so as to
be located, in use, immediately adjacent to, or centered on, the
ankle of a user.
[0015] In particular, the weight receiving pockets are preferably
positioned so as to be immediately adjacent to either the lateral
or medial malleolus portions of the ankle. Still more preferably,
weights are positioned adjacent to both the lateral and medial
malleolus portions so that a balanced amount of weight is applied
to sides of the ankle.
[0016] It is to be noted that the ankle is primarily a "hinged"
joint capable of moving the foot in two primary directions; away
from the body (plantar flexion), and toward the body
(dorsiflexion). It is formed by the meeting of three bones. The end
of the shin bone of the leg (tibia) and a small bone in the leg
(fibula) meet a large bone in the foot, called the talus, to form
the ankle. The end of the shin bone (tibia) forms the inner portion
of the ankle, while the end of the fibula forms the outer portion
of the ankle. The hard bony knobs on each side of the ankle are
called the malleoli, with the outside of the ankle being the
lateral malleolus, and the inner portion of the ankle being the
medial malleolus.
[0017] In essence, the foot rotates around the ankle through a line
between the lateral and medial malleolus. As such, ensuring that
the weights of the weight system of the present invention are held
immediately adjacent to, or centered on, the lateral and/or medical
malleolus, ensures that there is little or no interference with the
normal rotation and movement of the foot. As such, the weights of
the present invention, provide a solid workout of the user's legs,
without excessive force being applied to the user's ankles.
[0018] In an alternative embodiment, the weight receiving pockets
can be integrally formed in the footwear, and thus eliminate the
need for straps or a form to hold the weight receiving pockets in
place. As such, in a further aspect, the present invention also
provides weighted footwear comprising footwear, one or a plurality
of integral weight receiving pockets attached to said footwear for
receiving and holding one or a plurality of weights, and one or a
plurality of weights for insertion into said weight receiving
pockets, and, wherein said weight receiving pockets are positioned
on said footwear so as to be located immediately adjacent to, or
centered on, the ankle of a user.
DETAILED DESCRIPTION OF THE INVENTION
[0019] In the present application, the term "foot weight" or
"weight system" is used to refer to a weight that is preferably
positioned on footwear. This can include a variety of different
types of skates, including, for example, ice skates, hockey skates,
figure skates, speed skates, in-line roller skates, roller skates,
or other similar devices such as roller blades, or the like.
However, the skilled artisan will be aware that the footwear weight
system of the present invention can be used in a wide variety of
other footwear applications, including for example, running shoes,
training shoes, track shoes, skiis, cross-country skiis, or the
like.
[0020] Further, while the present application is described
hereinbelow with particular reference to the skate industry, and in
particular, the hockey skate industry, the skilled artisan would be
well aware that the present invention is equally applicable for use
in other types of footwear.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0029] The novel features which are believed to be characteristic
of the present invention, as to its structure, organization, use
and method of operation, together with further objectives and
advantages thereof, will be better understood from the following
drawings in which a presently preferred embodiment of the invention
will now be illustrated by way of example only. In the drawings,
like reference numerals depict like elements.
[0030] It is expressly understood, however, that the drawings are
for the purpose of illustration and description only and are not
intended as a definition of the limits of the invention.
[0031] Referring to FIGS. 1 to 4, a foot weight device 10 is shown
attached to a skate 12, in FIGS. 1 and 2, and shown separately
without the skate in FIGS. 3 and 4.
[0032] Skate 12 comprises a boot section 14 on which is mounted a
skate blade 16. Device 10 has an outer shell, generally shown as
11, which is adapted to be fitted around the ankle section of boot
14, and extend across the front of the user's foot.
[0033] Weight device 10 has a strap 20 which extends from a first
end 22 of device 10, through a D-ring 24 located on a second end 26
of device 10, and then attached, by a Velcro.TM. fastener 21 to the
first end 22. As such, device 10 is held in position on the skate
boot 14.
[0034] On each side of device 10, as shown in FIG. 1, there is a
weight receiving pocket 30, which is adapted to receive one or more
weights 60. Each of pockets 30 have an optional cover 32, which are
held in place by additional Velcro fasteners 31. As best seen in
FIG. 4, each weight receiving pocket 30 is separated into three
compartments 34 so as to receive up to three weights. A suitable
weight 60, is shown in FIG. 6, which is adapted so as to fit within
any one of compartments 34.
[0035] An optional additional strap 40 is attached to device 10,
and is adapted to pass under boot 14, above skate blade 16, through
D-rink 41, and back, in order to hold device 10 in place, using
Velcro fasteners 33.
[0036] Details of the construction of device 10 are shown in FIG. 5
in which device 10 from FIGS. 1 to 4 is laid flat. The various
components from FIGS. 1 to 4 can be seen, including D-ring 41
through which strap 40 passes and then returns to attach to a
further Velcro fastener 33. One of pockets 30 is shown in an open
position so that the three weights 60, in the three compartments
34, can be seen.
[0037] Weights 60 can be manufactured from any suitable material.
However, a solid weight (as opposed to loosely packed or granular
materials such as sand, iron shot or the like) is preferred. Most
preferably, the weight is a steel bar which has been coated with a
plastic material, such as a vinyl coating which has been applied by
dipping the weight in a plastisol coating material, in order to
prevent rusting or corrosion of the steel component.
[0038] Typically, each weight 60 will weight approximately 0.5
pounds (229 gram) to 1 pound (458 g) each. With a total of six
compartments per foot, the total weight will be approximately 3 to
6 pounds (1.374 to 2.748 kg). The number of weight compartments 34
and the weight of weight 60 can vary so as to preferably provide a
total weight on each foot of between 100 g and 3 kg, and more
preferably, between 300 and 2.5 kg.
[0039] The number of compartments 34 per foot is preferably between
1 and 5, and most preferably, between 2 and 4. Each weight can be
essentially identical in size, shape and weight, and has a weight
between 25 and 600 g, and more preferably, between 200 and 500 g.
However, different weight sizes and shapes might also be used, and
compartments 34 can vary in size and shape to hold different weight
sizes.
[0040] Preferred suitable weights are vinyl coated steel bars
having a length of 10 cm, a width of 2.5 cm, and a depth of 1.25
cm, and having a weight of 0.5 pounds (229 gram). A larger weight
would have a length of 10 cm, a width of 2.5 cm, and a depth of 2.5
cm, and having a weight of 1 pounds (458 gram). Compartments 34 are
preferably sized so as to receive either the 0.5 (229 g) or 1 pound
(458 g) weights.
[0041] Weight device 10 is preferably constructed primarily of a
strong outer shell suitable for use in the present application.
Preferred materials include ballistic nylon, cordura nylon,
neoprene, cotton, cotton mix, polyester, polyester mix, leather, or
rubber coated latex materials. Most preferably, the outer shell is
made of ballistic nylon.
[0042] The straps can be made from any suitable material, but
preferably are nylon straps. The straps are preferably held in
place by looping the strap through a D-ring, and using Velcro
fasteners to hold the end of the strap in place. Using, this
system, device 10 can be custom fitted to the user. However, other
fasteners such as buckles, hooks, buttons, clasps or the like,
might also be used.
[0043] The D-rings can be made of plastic or metal, or the like,
and are sized so as to receive the straps utilized. The straps are
preferably between 2.5 and 5 cm in width, and the D-rings are sized
so as to receive these straps.
[0044] The weight device 10 is particularly suited for use on a
skate, and in particular a hockey skate. However, device 10 can be
fitted to other types of skates or footwear, as described
hereinabove.
[0045] In FIG. 7, a shoe 100 is shown which integrally incorporates
the weight receiving pockets 102, and thus eliminates the need for
straps to hold the weight receiving pockets in place. Otherwise,
however, the weight system when used for shoe 100 is essentially
identical to the weight system described in respect of FIGS. 1 to
6.
[0046] Thus, it is apparent that there has been provided, in
accordance with the present invention, a foot weight device for use
on footwear, which fully satisfies the goals, objects, and
advantages set forth hereinbefore. Therefore, having described
specific embodiments of the present invention, it will be
understood that alternatives, modifications and variations thereof
may be suggested to those skilled in the art, and that it is
intended that the present specification embrace all such
alternatives, modifications and variations as fall within the scope
of the appended claims.
[0047] Additionally, for clarity and unless otherwise stated, the
word "comprise" and variations of the word such as "comprising" and
"comprises", when used in the description and claims of the present
specification, is not intended to exclude other additives,
components, integers or steps.
[0048] Moreover, the words "substantially" or "essentially", when
used with an adjective or adverb is intended to enhance the scope
of the particular characteristic; e.g., substantially planar is
intended to mean planar, nearly planar and/or exhibiting
characteristics associated with a planar element.
[0049] Further, use of the terms "he", "him", or "his", is not
intended to be specifically directed to persons of the masculine
gender, and could easily be read as "she", "her", or "hers",
respectively.
[0050] Also, while this discussion has addressed prior art known to
the inventor, it is not an admission that all art discussed is
citable against the present application.
