Description
[0001] This invention falls within the field of personal
protection. More specifically, it relates to a device for
protecting an area of the human body including a joint.
[0002] A particularly preferred field of application of this device
is the protection of an area of the body that comprises a joint
connecting two portions of a limb, such as a knee or elbow. The
device according to the invention can, however, be used equally
well for protecting other portions of the body comprising a joint,
e.g. the shoulder, hip, instep, etc.
[0003] The device according to the invention finds application in
personal protection in all fields, for example, but not
exclusively, in the military, paramilitary, security fields, and
also in the field of sports, of work, or, in general, in any field
where protecting a portion of the body is desired.
[0004] Protective devices, of the kneepad or elbow-pad type, are
known from the prior art, for example intended to enter into the
constitution of military combat clothing. In the most common types
these devices are made of a rigid outer protective cup, formed in
the general shape of a knee or an elbow, lined inside with padding
on a side designed to be placed facing the user's body. These
articles also comprise lateral straps for securing them in place
and keeping them on the body.
[0005] Such kneepads or elbow-pads of the prior art present a
number of drawbacks. In particular, they are not very comfortable
to use and they hamper the user's movements, which for the user,
for example a soldier or civil protection officer in action, may be
disadvantageous.
[0006] This invention aims to remedy the drawbacks of the existing
devices for protecting an area of the human body comprising a
joint, e.g. the knee or elbow, by proposing such a device that is
comfortable to use and that hampers the movements of the person
equipped with it as little as possible.
[0007] To this end, a device is proposed according to this
invention for protecting an area of the human body including a
joint. This device comprises an outer shell made of an elastically
deformable, semi-rigid, material and an inner shock-absorbing
protective element, intended to be placed facing the body. This
device is able to be deformed laterally so as to match the shape of
the body in said area including the joint, and it comprises
retaining means for maintaining same in each given lateral
deformation position, more specifically in each lateral deformation
position which it is possible to impose on it.
[0008] The outer shell and the inner protective element each
comprise a first side and a second, opposite, side. `Inner
protective element` means, in this description, an element to be
placed with its first side, called `inner side`, facing towards the
body. `Outer shell` means that the shell is to be placed away from
the body with respect to the inner protective element. According to
the invention a first side of this outer shell, called `inner`, is
placed facing the second side of the inner element, i.e. the side
of the inner element designed to be fitted facing away from the
body when the device is in use.
[0009] The device according to the invention can advantageously be
shaped laterally, so that it is able to present any lateral
deformation position desired, and thus to adjust to the specific
morphology of any user, by matching the shape of the latter's body
in the area comprising the joint for which protection is desired.
It is noted here that the device according to the invention is
intended to be placed against the user's body in a position wherein
its axis referred to as longitudinal is substantially parallel to
the axis of the portion of the body to be protected, e.g. of a leg
or an arm. Once shaped into this optimal position, the device is
advantageously kept blocked by the retaining means so that, shaped
precisely to match the shape of each individual user's body, it
provides the user with great comfort in use and at the same time a
high level of protection, because of its semi-rigid shell and its
inner shock-absorbing element.
[0010] According to preferred embodiments, the invention also
exhibits the following features, implemented separately or in each
of their technically possible combinations.
[0011] In preferred embodiments of the invention, the device
comprises means of folding along a transverse axis. Preferably, the
device comprises, along a longitudinal axis, a first portion
intended to cover the targeted joint, e.g. the kneecap or the
elbow, and a second portion intended to cover a portion of a limb
next to this joint, e.g. the upper area of the tibia or the
forearm, so as to protect this area when pressed against a hard
surface, e.g. when kneeling or when the elbows are leaning on such
a surface. The first portion and the second portion are
advantageously connected by an area, called `folding area`, for
folding along a transverse axis of the device, intended to be
placed at the flexing area of the joint.
[0012] This folding area advantageously forms a hinge articulating
the first portion and the second portion relative to each other,
along a transverse axis of the device. The hinge thus formed allows
the device to be deformed at the same time as the body of the user
according to the user's movements, in particular the flexion and
extension movements of the joint, continuing to match the shape of
the portion of the body against which it is applied. As a result,
the device according to the invention advantageously does not
hamper the user's movements; on the contrary it follows them so
that it provides optimum protection regardless of the
circumstances, together with great comfort of use.
[0013] Preferably the width of the folding area, measured along a
transverse axis of the device, is less than the width of the first
portion and the second portion. Thus advantageously, the device has
two lateral cut-outs at the folding area. Preferably the folding
area also has sufficient height, measured along a longitudinal axis
of the device, so that the first portion and the second portion
never overlap, even when the device is completely folded on
itself.
[0014] Preferably, the device has an outer contour adapted to the
shape of the limb. In particular, it has generally curved shapes,
so as not to hurt the user, and/or respectively upper and lower
edges that are concave.
[0015] In preferred embodiments of the invention, the retaining
means for maintaining the device in each given lateral deformation
position comprise at least one, preferably a plurality of,
deformable rigid transverse inserts, preferably metallic, secured
to the shell. These inserts can either be assembled on a side of
the shell, preferably on a side, called `inner`, placed facing the
inner protective element, or included in the thickness of the
shell. Their rigidity is both sufficiently low so that they can be
deformed manually and sufficiently high so that, once deformed,
they retain the shape imposed on them for a long time, regardless
of the movements of the user equipped with the device. In the
device's normal configuration of use, the inserts are thus
positioned transversally to the limb, and deformed so as to locally
match the shape of the limb.
[0016] Preferably, the device comprises at least two retaining
inserts placed respectively either side of the folding area. Such a
configuration advantageously makes it possible in particular to
maintain the device firmly against the user's limb in the area
stressed most during movements, around the area where the joint
flexes. This results in significantly increased protection for the
joint area and comfort in use.
[0017] In preferred embodiments of the invention, the device also
comprises an additional insert positioned at its lower edge, so as
to match the shape of the body as closely as possible in this
place. This insert preferably has a lower edge with the same shape
as the lower edge of the outer shell, preferably a concave
edge.
[0018] According to an advantageous feature of the invention, the
shell comprises, on a side called `inner` facing the inner
protective element, a peripheral rim with extra thickness,
advantageously allowing it to be strengthened.
[0019] In preferred embodiments of the invention the shell is
provided on its contour with folding notches. These notches are
preferably arranged in the thicker peripheral rim. Their number and
position on the shell's periphery can vary and are preferably
chosen so as to favor the device's articulation along axes that are
defined in a suitable way to allow optimum freedom of movement for
the user equipped with the device.
[0020] Preferably, the shell comprises at least one, preferably a
plurality of, series of through-slots forming fold lines. These
fold lines are arranged so as to facilitate the user's movements,
preferably in the continuity of the folding notches.
[0021] In preferred embodiments of the invention the shell is also
pierced by a plurality of through holes, called `ventilation
holes`, distributed over its surface, and advantageously favoring
the evacuation of perspiration.
[0022] The shell also preferably comprises, on a side called
`outer`, means of absorbing shocks, especially in the form of
hollow cells, extending from this outer side in the direction
opposite from the inner protective element. These cells can have
any shape, e.g. round, oval, square, triangular, etc.
[0023] Preferably, the outer shell is made in a single piece. The
inner protective element is also preferably made in a single
piece.
[0024] The outer shell and the inner protective element are also
preferably configured and arranged with respect to each other so
that their facing sides substantially coincide with each other via
their outer contour.
[0025] The device complying with one or more of the above features
advantageously offers a high level of protection for the joint and
a portion of an adjacent limb, together with significant comfort in
use, in that it causes little hindrance to the user in movement. It
is also able to be adjusted to the specific morphology of the user,
and to deform itself at the same time as the joint and the adjacent
portion of the limb that it is intended to protect.
[0026] The outer shell and the inner protective element can be
secured to each other by any fastening means standard in itself, it
being understood that this fastening means must not cause any
hindrance or any risk of injury for the user.
[0027] In preferred embodiments of the invention, the device also
comprises means of assembly to a system for fastening on the body,
in particular loops for inserting fastening straps around the
targeted limb.
[0028] The invention will now be described more precisely in the
context of preferred embodiments, that are in no way limiting,
shown in FIGS. 1 to 3, wherein:
[0029] FIG. 1 shows a perspective view of a protective device
according to the invention, seen from the outer shell side;
[0030] FIG. 2 shows a perspective view of the device of FIG. 1,
seen from the inner protective element side;
[0031] and FIG. 3 shows the side called inner of the outer shell of
the device of FIG. 1.
[0032] A device according to the invention for protecting an area
of the human body comprising a joint, for example a knee or an
elbow, also able in particular, but not exclusively, to be
designated by the terms kneepad or elbow-pad, is shown in FIGS. 1
to 3.
[0033] This device comprises an outer shell 10 and an inner
protective element 20, which have substantially identical general
shapes and which are assembled together by their respective sides,
called `inner side` 101 for the outer shell 10, and `outer side`
for the inner protective element 20.
[0034] In the device's normal position of use for protecting a
joint area of the human body, the inner protective element 20 is
intended to be applied by a side called inner 201, visible in FIG.
2, against the joint to be protected, a side called outer 102 of
the outer shell 10 then being positioned on the side away from the
body. The device is also intended to be positioned on the portion
of the body to be protected such that its longitudinal axis X is
substantially parallel to the longitudinal axis of the portion in
question, e.g. to the longitudinal axis of a lower limb, the leg,
or an upper limb, the arm.
[0035] As shown in FIG. 1, the outer shell 10, and also the inner
protective element 20, have generally curved outer contours, with
no protruding angles, so as to not cause a risk of injury for the
user.
[0036] Both the outer shell 10 and the inner protective element 20
comprise two portions extending each to the other along the
longitudinal axis X, of which a first portion, called `upper
portion`, respectively 103, 203, intended to be positioned at the
joint itself, e.g. the kneecap or elbow, and a second portion,
called `lower portion`, respectively 104, 204, intended to be
positioned at a portion of a limb next to this joint, e.g. the
upper portion of the tibia or the forearm.
[0037] These two portions are connected to each other by an area
called `folding area`, respectively 105, 205, which is preferably
formed at the site of two opposite lateral cut-outs in the device.
The width of this folding area 105, 205 is thus preferably smaller
than that of the first and second portions. It is configured so as
to allow the device to be folded along a transverse axis
substantially perpendicular to the longitudinal axis X, and
consequently to allow the relative movements of the first and
second portions with respect to each other.
[0038] The outer shell 10 is made of a semi-rigid elastically
deformable material, so that it is able to be deformed, especially
until a position in which it is able to match the shape of the limb
against which the device is applied. It is in particular made of a
polymer material, preferably compatible with an injection forming
method, preferably based on a thermoplastic polymer, for example a
polyolefin or polyurethane.
[0039] The protective element 20 is preferably in the form of a
foam sheet able to absorb shocks, made of a flexible material, for
example a polyolefin, polyethylene or polypropylene, polyvinyl
chloride, rubber, polyurethane, etc. Its density is preferably
between 30 and 300 kg/m.sup.3. Preferably, on the inner side 201 of
the protective element, this foam is covered by a protective layer,
in particular fabric, which ensures its cohesion during the
device's use.
[0040] In variants of the invention, the inner protective element
20 is formed by superimposing several foam sheets of different
compositions, e.g. a more comfortable foam sheet placed towards its
inner side 201, and a sheet of foam with greater ability to absorb
shocks placed towards its outer side.
[0041] The device according to the invention, comprising this outer
shell 10 and this inner protective element 20, is in particular
able to be deformed laterally, i.e. by folding on itself parallel
to the longitudinal axis X, such that it can advantageously be
deformed so as to adopt a complementary shape to the shape of the
limb against which it is to be applied, whatever the specific
morphology of the user.
[0042] The upper, respectively 106, 206, and lower, respectively
107, 207, edges of the shell 10 and the inner protective element 20
are also preferably slightly concave, so as to be able to follow
the contours of the limb, e.g. leg or arm, against which the device
deformed laterally in this way is applied.
[0043] The outer shell 10 comprises at least one series of
through-slots 108 forming a fold line. Preferably, a fold line 110
transverse to the longitudinal axis X, visible in FIG. 3, is formed
in this way at the folding area 105.
[0044] Other fold lines can be formed in the outer shell 10, so as
to favor its folding along given axes.
[0045] As an example, FIG. 3 shows, in addition to fold line 110, a
cross-fold line 111, positioned in the second lower portion 104,
and two longitudinal fold lines 112, 112', extending over the
entire length of the shell 10 substantially parallel to the
longitudinal axis X, preferably symmetrical with respect to this.
All these fold lines favor the device's preferred articulation
along different predefined axes, and advantageously allow it to be
deformed according to the user's movements, while continuing to
match the shape of its limb thus protected.
[0046] The shell 10 also comprises a peripheral rim 109 with extra
thickness, which strengthens it by making it locally more
rigid.
[0047] At this rim, it is preferably pierced by notches, called
`folding notches` 120, preferably distributed on its contour, which
advantageously favor the shell's folding on itself along given
axes. The number and arrangement of these notches can vary. Notches
120 are preferably positioned in the alignment of each fold line
110, 111, 112, 112'.
[0048] The shell 10 is also preferably pierced by through holes 113
distributed over its surface, which favor the evacuation of
perspiration.
[0049] Cells 114 are formed on the outer side of the shell 10.
These cells advantageously play a role in absorbing shocks exerted
on the shell from the external environment. Their number and shape,
and their position on the shell's surface, can easily be determined
by the person skilled in the art so as to ensure the best
shock-absorbing capability for the shell 10.
[0050] The device also comprises means able to maintain it in each
given lateral deformation position. In the particularly preferred
example of realization shown in FIG. 3, these retaining means
consist of inserts 30, in the form of strips, arranged
transversally to the longitudinal axis X, preferably so as to
extend substantially over the entire width of the device, and
having a rigidity that is both sufficiently low so that they can be
deformed manually and sufficiently high so that they retain the
shape imposed on them under the device's normal conditions of use,
i.e. when it is placed on a limb of the human body, such as the leg
or arm, to protect its joint and the portion of the limb next to
it.
[0051] These strips 30 are preferably made of metal, for example
aluminum.
[0052] Preferably, at least two strips 30 are respectively
positioned either side of the folding area 105, so as to keep the
device in shape in the lateral deformation position imposed on it
either side of the flexing area of the joint, the area where the
most stress is exerted on the device as a result of the user's
movements.
[0053] In the preferred example of realization shown in FIG. 3, a
third strip 30' is positioned near the lower edge 107 of the shell.
It preferably has a lower edge 302' with a concave shape similar to
the shape of this lower edge 107. This strip 30' ensures that the
device's shape is maintained at its lower edge.
[0054] The strips 30, 30' are assembled in the device in an area
where they will not cause any risk of injury for a person wearing
the device, or for a person nearby.
[0055] Preferably, these strips 30, 30' are positioned between the
inner protective element 20 and the outer shell 10, preferably
fixed against the latter's inner side 101. In alternative
embodiments, the strips 30, 30' can be included in the very
thickness of the shell, during the latter's manufacturing process,
for example by an injection molding method.
[0056] The strips 30, 30' can be assembled to the shell 10 by any
means standard in itself.
[0057] Similarly, the inner protective element 20 can be assembled
to the shell 10 by any means standard in itself.
[0058] In the preferred embodiment that is the subject of the
figures, the means of fastening firstly the protective element 20,
and secondly the strips 30, 30', to the shell 10, are the same.
[0059] As shown in FIG. 3, these fastening means comprise a
plurality of fastening studs 115 arranged on the peripheral edge of
the shell, on its inner side 101. Each of these studs is pierced in
its center by a hole 116, inside which can be clipped a lug 117
borne at the end of a tab 118 secured to the shell 10 in an area
close to the cooperating stud 115.
[0060] The protective element 20 is pierced by holes, in areas
arranged facing the studs 115 when the shell 10 and the protective
element 20 are aligned with each other so as to put their outer
contours substantially into alignment.
[0061] The protective element 20 and shell 10 are assembled by
inserting the shell's studs 115 into the cooperating holes in the
protective element 20, then folding the tabs 118 so as to insert
each lug 117 into a hole 116. A solid fastening can then be
achieved, in particular by ultrasonic or high-frequency welding,
gluing, thermal welding, clipping lugs 117 in the holes 116, or by
any other fastening means standard in itself. The length of the
tabs 118 is preferably advantageously fixed so that, when the lugs
117 are clipped in the holes 116, the inner protective element 20
is pressed against the shell 20 by the tabs 118, as shown in FIG.
2, in several areas of its periphery.
[0062] The studs 115 are also preferably positioned so that at
least one pair of studs is respectively aligned on each of the
transverse lines coinciding with the desired position for each
strip 30, 30' along the inner side 101 of the shell. Each strip is
pierced at its opposite ends by a through-opening 301 able to
receive a stud 115.
[0063] Before the protective element 20 is assembled on the shell
10, each strip 30, 30' is positioned against the shell 10, by
inserting a stud 115 into each cooperating opening 301. The
protective element 20 is then in its turn put in place on the studs
115, so that the strips are then held wedged between the shell 10
and the protective element 20. The fastening is then implemented as
described above.
[0064] For its use, the device according to the invention can, for
example, be inserted into a pocket of an item of clothing worn by
the user, in particular a pocket provided for this purpose in an
item of military combat clothing.
[0065] Alternatively it can be fixed directly around the area of
the body to be protected. For this purpose, it is provided with
means of assembly to a system for fastening on the body. In
particular, this system is comprised of fastening straps that are
self-closing, in particular by fastening means such as
self-gripping bands, of the hooks and loops type, or any other
fastening means standard in themselves, such as, for example,
buttons called press-studs. For this purpose, the shell 10 can for
example be fitted with pairs of cooperating lateral loops 121 for
such fastening straps.
[0066] The device according to the invention can advantageously be
delivered as a flat shape, saving space. When a person wishes to
use it, he applies it against the desired portion of his limb, at
the joint, positioning the first portion 103, 203 at the joint
itself, and the second portion 104, 204 at the associated portion
of the limb. He shapes the devices, by deforming it laterally, to
bring it to a position in which it locally matches the shape of his
limb. This operation is easy and quick to carry out. At the end of
this, the device advantageously retains this lateral deformation
position.
[0067] The device held attached against the user's limb offers the
limb effective protection against shocks and external pressure. It
is also comfortable in use since, firstly, it is adjusted to the
specific morphology of the user and, secondly, it is able to be
deformed at the same time as the area of the body against which it
is applied, in particular, but not exclusively, at the flexing area
of the joint, thanks in particular to the presence of the different
fold lines and folding notches provided on the shell 10. In
particular, the device is articulated at the folding area 105, 205,
which allows the relative movements of the first portion and second
portion during flexion and extension movements of the joint.
[0068] The above description clearly illustrates that, through its
various features and their advantages, the present invention
realizes the objectives it set itself. In particular, it provides a
device for protecting an area of the human body including a joint,
which is notably especially suited to a military or paramilitary
use, in that it effectively protects the joint and a portion of an
associated limb while allowing flexion and extension movement and
causing little hindrance to the user's freedom of movement.
