Description
This invention relates generally to new and useful improvements in
protective arm pad devices, especially for use in sports. The
invention was made having in mind particularly providing protection
for lacrosse players, but is of more general application in
connection with sports involving bodily contact.
BACKGROUND OF THE INVENTION
In many athletic sports, players are subjected to body contact
either with other players or with game equipment, such as lacrosse
sticks. The prior art has provided various kinds of arm protective
devices which may be used in such sports. Examples are to be found
in the patents to Sotherlin U.S. Pat. No. 3,322,118 and Enicks U.S.
Pat. No. 3,446,880, which disclose arm protective devices intended
to protect the wearer's elbow and portions of the wearer's biceps
and forearm. The Sotherlin patent discloses a rubber pad for
protecting the elbow point. The Enicks patent discloses a pad
formed of plastisol provided with an outer skin. Various arm
protective devices including some comprising a plurality of parts
have been proposed in the prior art. The prior art arm protective
devices known to the applicants are believed not to have all that
is desired from the standpoint of a balancing of the factors of
light weight, ample protection of the biceps, forearm and elbow,
resilience and flexibilty, and adaptation to being fitted to an
individual wearer's arm, from the standpoints of providing
protection, comfort or feeling to the wearer, and minimum
interference with free arm movement.
SUMMARY OF THE INVENTION
The present invention seeks to provide an arm protecting device
having improved qualities as to weight, protection of the biceps,
forearm and elbow, resilience and flexibility, allowing relatively
free arm movement, and ease of fitting to the individual wearer's
arm. A general object of the invention is to provide such an
improved arm protective device comprising a flexible, resilient,
cushioning pad which is so contoured or shaped as to be capable of
being wrapped around a wearer's arm and fitted with considerable
individuality respectively to the biceps, forearm and elbow.
Another object of the invention is to provide an arm protective
device including a flexible pad which may be flattened out
relatively in a non-use position and which includes an elbow
portion intervening between and connecting a forearm portion and a
biceps portion, the pad having two longitudinally spaced parts
between the elbow portion and the biceps and forearm portions,
respectively, which are of less lateral extent than the biceps and
forearm portions, the pad parts of less lateral extent contributing
to the capability of the biceps, forearm, and elbow portions being
shaped individually to the arm.
Further objects of the invention will be apparent from a reading of
the following description, the claims, and the accompanying
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings:
FIG. 1 is a perspective view of an arm protective device embodying
the invention, shown formed substantially as it would be when
applied to the arm of a wearer;
FIG. 2 is a plan view of a pad which is part of the device, shown

arm, bent at the elbow.
DETAILED DESCRIPTION
The embodiment shown in the drawings for illustrating a preferred
form of invention comprises a unitary pad P of flexible resilient
material which may be deformed from its relatively flattened-out,
non-use condition shown in FIG. 2 to the relatively wrapped-around
positions shown in FIG. 4 and 5 in use as applied to a wearer's
arm, and means, generally designated SM1, SM2, SM3, SM4 and SM5,
for shaping the pad to conform substantially to the wearer's
arm.
The pad P comprises a relatively thick body or core C of flexible,
resilient, cushion material and a relatively thin coating or skin S
(indicated in FIG. 3) which is preferably relatively smooth as
compared to the material of the core C were it not covered by the
skin S. A presently preferred material C comprises a closed cell
rubber, and the skin S may comprise closed cell polyvinyl chloride
material the cells of which are more closed than those of the core
C. The skin may be applied to the core by dipping the latter in the
skin material, the skin thereafter being cured to provide a smooth
surface for the pad. The core C desirably has a compression
deflection of 4-8 p.s.i. (ASTM D-1056-68), a density range (PCF)
average 5-10, a water absorption range up to 10% maximum by weight,
a compression set of 50% (average) in a test sample one-half inch
thick compressed 22 hours at 70.degree.F. with a recovery of 15-25%
in 24 hours. Linear shrinkage is a maximum of 5% when aged 7 days
at 158.degree.F. The aforesaid properties are retained under
relatively sustained temperature exposure from 20.degree.F. to
130.degree.F. and under intermittent short exposure to
200.degree.F. A suitable and presently preferred material is closed
cell rubber R-310-V dip coated with vinyl SBE-41-42, a polyvinyl
chloride, provided by Rubatex Corporation Division of Groendryk
Manufacturing Company, Incorporated, of Buchanan, Virginia.
Dimensions of the pad may vary according to different arm sizes. In
a typical pad, the thickness is one-half inch and the maximum
longitudinal dimension is approximately 17 inches. Generally, the
same thickness may be employed for pads of somewhat different
lengths.
Referring particularly to FIG. 2 which shows the pad P in its
flattened non-use condition, the pad comprises three main portions
longitudinally generally in line with each other, namely a biceps
portion BP, a forearm portion FP and an elbow portion EP, all
formed integrally and of lateral and longitudinal extents
sufficient partially to encompass a wearer's arm. The flattened-out
pad P is contoured in outline to enable the biceps portion BP, the
forearm portion FP and the elbow portion EP to be shaped in place
separately to a wearer's biceps, forearm and elbow, respectively.
The elbow portion EP is constituted by a main or central part EP1
and two ears EP2 and EP3 of modified triangular shape projecting
outwardly from the central part EP1, the ear EP2 being longer than,
that is it extends laterally outwardly more than, the ear EP3. The
biceps portion has two lateral edge parts or portions BP1 and BP2.
The forearm portion FP is shown as and may usually be substantially
a mirror image of the biceps portion BP.
The elbow portion generally designated EP intervenes between the
biceps portion BP and the forearm portion FP, and the ears EP2 and
EP3 extend oppositely outwardly from the laterally opposite sides
of the central part EP1 of the elbow portion EP.
Relief spaces R1, R1 in the periphery of the pad intervene between
the ear EP2 and the laterally extending side parts BP1 and FP1 of
the biceps portion BP and the forearm portion FP, respectively. The
relief spaces R1 facilitate separate or more or less individual
shaping of the laterally extending parts BP1 and FP1 and the ear
EP2 to different portions of a wearer's arm when applied. Thus,
each part BP1 and FP1 and the ear EP2 may be deformed differently
from the deforming of the other two of these parts according to the
configuration of the wearer's arm and the wearer's individual
preference as to fit, having regard both to comfort and to
secureness in place.
Along the other longitudinal side and in the periphery of the pad
are relief spaces R2, R2 between the ear EP3 and lateral side edge
parts BP2 and FP2 of the biceps portion BP and the forearm portion
FP, respectively. The ear EP3 is somewhat shorter laterally and
more narrow longitudinally of the pad than the ear EP2. The relief
spaces R2 are convergingly narrower from the outer end of the ear
EP3 toward the central part EP1 of the elbow portion EP and
terminate in roots RO which are wider than the narrowmost parts of
these relief spaces. The wider roots cause more efficient
distribution of stress in the pad material when the parts BP2 and
FP2 and the ear EP3 are curved or otherwise formed to different
extents when being applied to a wearer's arm, thus inhibiting
splitting or other failure of the pad material adjacent the relief
spaces R2, R2.
As may be seen in FIG. 2, the pad P, formed as outlined above,
includes two longitudinally spaced pad parts (unnumbered) which are
located between and merge with the elbow portion EP and the biceps
and forearm portions BP and FP, respectively, these pad parts being
of less lateral extents than the biceps portion EP, the forearm
portion FP and the elbow portion EP considered in it entirety as
including the central part EP1 and the ears EP2 and EP3. These two
pad parts of less lateral extents contribute to the ease of shaping
the portions BP, FP and EP to fit the wearer's arm.
As shown in FIG. 2, center lines CL of the biceps portion BP and
the forearm portion FP intersect within the central part EP1 of the
elbow portion EP at an obtuse angle a.
Reference will now be made to the shaping and securing of the pad
portions BP, FP and EP to the wearer's arm. Desirably, separate
shaping and securing means are provided for use in connection with
the pad portions BP, FP and EP. In the form shown separate straps
SM1-SM5, which advantageously may be elastic, are provided.
The pad biceps portion BP is formed with four slits, two 10 being
near the free end of the portion BP, and the other two 11 being
adjacent the merging of the portion BP with the elbow portion EP.
The elastic straps SM1 and SM2 are threaded through the slits 10
and 11, respectively, and extend across that face of the pad which
is to be positioned next to the wearer's arm. The straps SM1 and
SM2 are looped from the opposite face of the pad with their ends
being closed adjustably by double ring type buckles or fasteners 12
of a known kind. Both rings of each fastener 12 are attached at 13
to one of the associated strap ends, the other strap end being
passed through both rings and returned to extend under one only of
the pair of rings. The length of the looped straps may thus be
adjusted by manipulation of the strap free ends in the rings in a
well known manner. In this way, the biceps portion BP may be shaped
readily to conform to the wearer's biceps.
The forearm portion FP is formed with slits 10 and 11 positioned
relatively to the portion FP similarly to the positioning of the
slits 10 and 11 in the biceps portion BP. The straps SM4 and SM5
are extended through the slits 11 and 10, respectively, and are
arranged in loop form similarly to the straps SM1 and SM2 as
described above, again double ring fasteners 12 being provided.
The securing strap SM3 for the elbow portion EP does not pass
completely around the pad so as itself to constitute a complete
loop. Instead, it extends across and spaced from that face of the
pad which is to be next to the wearer's arm, and its ends extend
only against the edge portions of the opposite face of the pad and
thence through slits 14, 14 shown in FIG. 1. The ends of the strap
SM3 are formed in the shape of a T. To insert the strap SM3 in the
slits 14, either one of the T-shaped ends is flexed to align the
cross of the T with the slit 14, enabling the strap to be inserted
through both slits and placed in the position shown in FIG. 1. The
initially inserted T-end of the strap is then restored to the
transverse position shown in FIG. 1 so that the strap SM3 is
relatively permanently attached to the ear portions EP2 and EP3 of
the elbow portion EP.
To apply the arm protective device to a wearer's arm, the straps
SM1, SM2, SM4 and SM5 with discontinuous ends may be loosened. The
wearer's arm is then extended lengthwise through the looped straps
SM1, SM2, SM4 and SM5 and between the strap SM3 and the elbow
portion EP. Then the straps SM1, SM2, SM4 and SM5 are adjusted so
as to conform the biceps portion BP and the forearm portion FP to
the wearer's biceps and forearm, respectively. If desired, the
straps held in loop form by the buckles 12, or some of those
straps, may be disconnected by the buckles so as to assist in
applying the pad to the wearer's arm.
The pad P is shown provided with ventilating holes V. The pad core
C may be die cut to its outline and to form the slits 10, 11 and 14
and the holes V, and the skin S then applied as described above to
cover the walls of the slits and the ventilating holes as well as
the core surfaces.
As stated above, a typical pad of one-half inch thickness has a
maximum longitudinal dimension of approximately 17 inches. In such
a pad, the maximum transverse width of either or both of the biceps
portion BP and the forearm portion FP is approximately 61/2 inches,
and the tip-to-tip transverse width of the elbow portion is
approximately 91/2 inches. In larger or smaller pads, the
dimensions would be substantially in the same proportions.
A device according to the invention is light and readily adjusted
to the individual wearer, both from the standpoint of comfort of
fit and the standpoint of providing good protection against blows
which may be encountered in sports, particularly in sports
involving contact such as lacrosse. At the same time, the pad is so
conformable to the wearer's arm as to protect a maximum area of the
arm with a minimum of interference with free arm action. Thus, the
reduced lateral extent of the central part EP1 of the elbow portion
EP taken in connection with the reduced areas of the ears EP2 and
EP3 minimizes interference with bending of the wearer's elbow while
at the same time providing the necessary protection of the elbow
point. In the illustrative embodiment, the pad is symmetrical from
end-to-end. By having it substantially symmetrical, it is equally
applicable to a right or a left arm by being reversed
end-to-end.
The arm protective device shown embodies the invention in a
preferred form, but the disclosure is intended to be illustrative
rather than definitive.
