Description
TECHNICAL FIELD
[0001] The present invention generally relates to a re-positionable
retention system that could be used to install in the internal
surface of face-shields, for example in motorcycle helmet's visors,
several type of devices.
BACKGROUND ART
[0002] During the last years there was a real proliferation in type
and the number of devices capable to facilitate and enhance the
visibility when driving with visor-equipped helmets. Such devices,
usually having the shape and features suitable for a wide
compatibility, (so-called "universal" models), are generally
installed inside the visor using very tenacious adhesive materials
that never allow the repositioning, or using mechanical systems
(ex. Pinlock, Pat. CA2640581) that need irreversible operations
like drilling the visor itself.
[0003] In the case of screens or devices that employ tenacious or
"permanent" adhesive materials, a particular care is required
during the installation phase. These screens, when removed, suffer
such alterations of their own features that they cannot be utilized
afterwards.
[0004] In the case of screens or devices that employ mechanical
retention systems, as it's needed to permanently modify the visor,
for example by drilling it, then the functionality of the visor
itself results often to be compromised when utilized in its
original configuration.
[0005] It's not therefore known, in the background art related to
face-shields, a retention system that could allow the detachment
and replacement of screens and devices without altering or
modifying their own features or the ones of the face-shield onto
which they are applied.
DISCLOSURE OF THE INVENTION
[0006] It is therefore a technical duty of the present invention to
counter above mentioned lacks and to satisfy hinted needs providing
a system that could allow the detachment and replacement of screens
and devices accessory to visors without altering or modifying their
own features or the ones of the face-shield onto which they are
applied.
[0007] In this technical duty's field, it is another object of the
present invention to preserve the visor itself and the accessory
screens from damages and/or premature replacements.
[0008] It is yet another object of the present invention to improve
the usability of such type of screens that can be this way employed
only when effectively needed and that can be therefore moved
between different helmets' visors. The above mentioned duties and
scopes are reached by the present retention system of the type that
can be used to install, in the internal surface of face-shields
(7), a variety of devices, like for example screens working as
solar filters, anti-glare screens, antifog screens, anti-scratch
screens or different types of screens or devices. This system can
be created exploiting the characteristics of some materials. The
system comprises a gasket glued to the screen near his own edges.
Such a gasket can be built using several materials like, for
example, closed cells acrylic foam layers (like Very High Bond, VHB
of 3M), or with a closed cells cross-linked polyethylene (like PEX
or XLPE of Sekisui Alveo), or closed cells polyurethane foam, or
other similar materials, with the possibility of adding adhesive
layers of different composition.
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Further details will ensue more clear and evident from the
detailed description of some embodiments that are preferred, but
not exclusive, of a removable retention system according to the
invention, instanced as a sample in the attached drawings, in
which:
[0010] FIG. 1 visually represents, in a schematic prospective view,
a retention system, according to the invention, applicable on a
protective helmet's visor.
[0011] FIG. 2 visually represents, in a schematic prospective view,
a retention system according to the invention, applicable on a
protective helmet's visor, comprising a single gasket.
[0012] FIG. 3 visually represents, in a schematic prospective view,
a retention system according to the invention, applicable on a
protective helmet's visor, comprising a multi-layered gasket.
BEST MODE FOR CARRYING OUT THE INVENTION
[0013] The description of some examples of embodiment follows here:
[0014] In case there is the purpose of building a gasket (2) (FIG.
2) of closed cells acrylic foam, for example using VHB (Very High
Bond) of 3M, it's to consider that is being employed a material
having high surface energy and intrinsic adhesive features, that is
self-conformable and that can enhance the contact between surfaces;
it's so possible to proceed as follows. Step 1) Treat one of the
two contact surfaces (4) (FIG. 2) of the gasket with solvent or
chemical compounds that can attenuate the adhesive power, like for
example the product "Leva Etichette" of Talken Color or other
products with the same utilizing features. After the treatment the
surface will offer a weak tenacity adhesion that will allow the
screen removal, but that will be enough to keep the screen itself
or other devices into the intended position (FIG. 2) and to allow
its use during the common conditions of employ. Step-2) Apply the
gasket letting the untreated surface (5) sticks to the screen (6)
(FIG. 2). Step-3) Apply the screen to the visor (10) letting the
treated surface (4) stick to the internal surface of visor (7)
(FIG. 2). The increment of efficiency of such system is promoted by
treating the involved surfaces (4)(7) with isopropyl alcohol based
solution and/or other analogous compounds. To reach this scope, the
suggested compounds are those suitable for cleaning surfaces having
optical features and those suitable for enhancing adhesive features
of acrylic foams that have been previously treated with the
solvents and chemical compounds described into "Step-1)". The
treatment with isopropyl alcohol based solution is the system's
main maintenance method, as it allows to recover the adhesive
features that tend to decrease after installing/uninstalling
repeated operations; however, any type of solving compound or
preparation that never releases excessive residuals after his
happened evaporation can be used as an alternative to isopropyl
alcohol based solution. [0015] In case there is the purpose of
building a gasket (2) (FIG. 3) of polyethylene or polyurethane
closed cells, it's to mind that said material has no intrinsic
adhesive features, so it's necessary to proceed as follows. Step-1)
Treat the contact surface (5) (FIG. 3) of the gasket (2) adding a
strong tenacity adhesive layer, like for example an FT126 Avery
Dennison acrylic adhesive or other adhesives having similar
physical features. Treat the surface (4) (FIG. 3) of the gasket
adding a re-positionable weak tenacity adhesive foam, like for
example an FT130 Avery Dennison acrylic removable adhesive or other
adhesives having similar physical features. Step-2) Apply onto the
re-positionable adhesive layer a second double-side adhesive
re-positionable gasket (3). Step-3) Apply the gasket letting the
side treated with strong tenacity adhesive (5) (FIG. 3) stick to
the surface (6) of the screen (1). Step-4) Apply the screen to the
visor letting the double-side adhesive re-positionable gasket (3)
to the visor (1) (FIG. 3). When this system will start suffering
the loss of efficiency of the re-positionable adhesive, due to the
repeated installation and removals of the so built screen, it will
be possible to restore it just substituting the double-side
adhesive re-positionable gasket (3). [0016] It constitutes a
further possible embodiment of the presented system the one in
which the second gasket (3) (FIG. 3) has a layer of strong tenacity
adhesive in the side that face the visor (10). In this case the
gasket (3) remains anchored to the visor (10) and the screen
becomes removable between the gasket (2) and the second gasket (3).
In this embodiment the gasket (2) (FIG. 3) can be built using
polyethylene, polyurethane or acrylic closed cells foam.
[0017] The gasket's adhesive effect is promoted by further factors
listed here: [0018] The motorcycle and driving helmet's visors
generally have a bended shape and semi-rigid type (10) (FIG. 1), as
they are mainly produced by injection moulding or laminated
material thermoforming. The screens that are utilized with the
visors generally have flat shape and flexible type (1) (FIG. 1), as
they are mainly produced cutting laminated material. These features
create a bending differential that give off a tension that can
promote the efficiency of the gasket's adhesive features between
the two considered elements (the screen and the visors). [0019] The
closed cells structure of the material of which it was decided to
build the gasket (2) can completely seal the cavity (8) that is
being created between the visor (10) and the screen (1) (FIG. 2,
FIG. 3). This feature, added to above mentioned tensions, those
created from the bending differential between the visor (10) and
the screen (1), generates a depression inside the cavity promoting
the gasket's (2) adhesion features.
