FIELD OF THE INVENTION
[0001]
This invention relates to barbells, and particularly
to those barbells Whose Weight can be altered With the
addition or removal of plates of different Weights.
BACKGROUND OF THE INVENTION
[0002] Barbells are commonly used for various exercises
such as curls, bench presses, and shrugs to build strength and
develop muscle mass. In addition, they are utiliZed in
competitive exercises, such as the snatch and the clean-and
jerk.
calculated.
[0012] According to a further aspect of the present inven
tion, there is provided a set of plates for a barbell, the set
comprising plates having different Weights, Wherein plates
of the same Weight are of the same color Which is a different
from that of at least some plates of different Weights.
[0013] The set may comprise a ?rst group of plates each
being of a ?rst Weight, and a second group of plates each
being of a second Weight, such that the ?rst Weight is a
product of the second Weight and a round factor of ten (such
as 10, 100, 1000, etc.), Wherein the plates of the ?rst and
second group are of the same color.
[0003] Typically, the Weight of a barbell may be adjustable
by the addition or removal of plates having knoWn Weights.
The Weight of each plate is noted on at least one of the faces
thereof. The bar is of a knoWn Weight, Which is typically 20
kg. The plates are typically provided in Weights of 0.5 kg, 1
kg, 1.5 kg, 2 kg, 2.5 kg, 5 kg, 10 kg, 15 kg, 20 kg, and 25
kg. In the US, Where the metric system is not Widely used,
bars and plates of the same Weights are used, either pre
sented in kilograms or in pounds (i.e., a 20 kg. bar is still
provided, but the Weight may be given as 44 lbs.).
[0004] In addition, barbell sets may be purchased for
[0014] For example, the set may comprise plates having
Weights of 50 lbs, 40 lbs, 30 lbs, 20 lbs, 10 lbs, 5 lbs, 4 lbs,
3 lbs, 2 lbs and 1 lb. The plates having Weights of 50 lbs and
5 lbs. are of a ?rst color, the plates having Weights of 40 lbs
and 4 lbs. are of a second color, the plates having Weights of
30 lbs and 3 lbs. are of a third color, the plates having
Weights of 20 lbs and 2 lbs. are all ofa fourth color, and the
plates having Weights of 10 lbs and 1 lb. are all of a ?fth
color. The ?rst, second, third, fourth, and ?fth colors are
different from one another.

DETAILED DESCRIPTION OF EXEMPLARY
EMBODIMENTS
[0027]
As seen in FIG. 1A, there is provided a barbell set,
used to assemble a barbell, such as that illustrated in FIG.
1B. The set comprises a bar 10 having tWo sleeves 16, a
plurality of plates 12 of varying Weights, and tWo collars 14.
When assembled, as seen in FIG. 1B, several of the plates
12 are arranged in tWo sets 18, one set toWard each end of
the bar 12. Each set 18 is retained betWeen a collar 14 and
a sleeve 16. The collar 14 is adapted to be secured to the bar
10 in order to ensure that the plates 12 do not slide about or
off the bar.
[0028] The bar 10 may be of a standard length, such as 6
or 7 feet, and Weighs 45 lbs. It may be straight, or bent,
several examples of Which are illustrated in FIG. 2. Portions
20 of the bar 10 betWeen the sleeves 16 may be knurled, in

It should be noted that the plates may have their
Weights indicated in pounds and/or in kilograms. This may
be advantageous, for example, for the plate having a Weight
of 27.5 lbs, Which is equivalent to 12.5 kg. A standard
order for a user to maintain a tight grip thereon.
Women’s kilogram bar has a mass of 15 kg. The addition of
tWo plates of 12.5 kg (i.e., 27.5 lbs.) to such a bar Will Zero
it to 40 kg.
[0029] Reverting to FIG. 1A, each plate 12 is a standard
plate, and thus comprises a central hole 22 siZed to receive
[0035] The plates 12 may be of varying colors, With plates
12 of different colors being of different colors, and plates of
the bar 10, and an indication 24 of its Weight, on one or both
the same Weight being the same colors. For example, all of
the 20 lb. plates may be green, all of the 30 lb. plates may
be yelloW, all of the 40 lb. plates may be blue, all of the 50
lb. plates may be red, all of the 27.5 lb. plates may be orange,
and all of the 52.5 lb. plates may be purple. This facilitates
sides thereof. The plates 12, according to one embodiment,
are all of the same color, and are provided in Weights of 20
lbs, 30 lbs, 40 lbs, 50 lbs, 27.5 lbs, and 52.5 lbs. In addition,
plates having Weights of 10 lbs, 5 lbs, 4 lbs. 3 lbs, 2 lbs, 1
lb, and 0.5 lbs. may be provided. By using the additional
plates, the Weight of the barbell may be increases in incre
ments of one pound While maintaining an equal Weight on
both groups.
[0030] The plates 12 may be circular or of any other
appropriate shape, such as octagonal or dodecagonal (see
FIGS. 3A and 3B). In addition, handles 26 may be formed
therein (as shoWn in FIG. 3A, but may be provided on a plate
12 according to any embodiment) in the form of holes.
[0031] As illustrated in FIG. 4A, the plates 12 may be of
different diameters corresponding to their Weights, or, as
illustrated in FIG. 4B, they may be of different thicknesses
corresponding to their Weights. Alternatively, a combination
differing diameters and differing thicknesses may exist
expedited choosing of a desired plate.
[0036] When plates of loWer Weights are also provided,
they may be provided in colors Which are different from
those of the heavier plates (i.e., 20 lb, 30 lb, etc.) or the color
scheme may be repeated, With similar colors being used for
plates Which are lighter by a factor of 10 (i.e., the 5 lb. plate
is red like the 50 lb. plate, the 4 lb. plate is blue like the 40
lb. plate, the 3 lb. plate is yelloW like the 30 lb. plate, the 2
lb. plate is green like the 20 lb. plate, and the 0.5 lb. plate
is red like the 5 lb. plate and the 50 lb. plate). In addition,
the 10 lb. plate and the 1 lb. plate are White.
[0037] The color of the plates may be provided by any
means. If the plates are solid metal, a cover made from
rubber, polyurethane, or other suitable material may be
Within a single set (e.g., plates 12 having Weights of 52.5 lbs,
provided. If the plates are made from a material Which can

have the same thickness as the 40 lb. plate, With the diameter
[0038] In addition to use With a barbell, it Will be appre
ciated that the plates 12 as described herein may be used
decreasing With the Weight). In addition, the diameter and
thickness may both vary according to the Weight of the plate.
[0032] In use, any combination of plates 12 may be added
to the bar. HoWever, it is particularly advantageous for a user
to place on the bar either the plates Which Weigh 27.5 lbs or
those Which Weigh 52.5 lbs. In this Way, the Weight of the bar
is Zeroed at 100 or 150 lbs, respectively. The arithmetic
necessary to determine the ?nal Weight of the barbell With
the addition of other plates can be done With relative ease,
since the barbell is Zeroed to a “round” Weight (i.e., a
“roun ” number of pounds).
[0033]
With other Weight-training equipment, such as plate-loaded
machines, such as a shoulder press and a bench press. These
machines are adapted to provide a speci?c exercise, and are
loaded With the same plates used for barbells. Several such
machines are illustrated in FIGS. 5A through 5C as non
limiting examples only.
[0039]
Those skilled in the art to Which this invention
pertains Will readily appreciate that numerous changes,
variations and modi?cations can be made Without departing
from the scope of the invention mutatis mutandis.
In addition to plates 12 having Weights of 27.5 lbs.
and 52.5 lbs, other sets of plates may be used to Zero the bar
at other round numbers, such as 60, 70, etc. Examples of
these additional plates are listed in the Table 1, below.
