CROSS-REFERENCES TO RELATED APPLICATIONS
[0001] This application claims the priority of Patent Application
Serial No. FR 11/02481, filed on 8 Aug. 2011, pursuant to 35 U.S.C
119(a)-(d), the content of which is incorporated herein by
reference in its entirety as if fully set forth herein.
TECHNICAL FIELD OF THE INVENTION
[0002] The invention relates to a unit composed of helmet and
protective eye mask, the unit comprising [0003] a shell-shaped
helmet cap comprising a fastening system, and [0004] an eye
protection element which, in a position of use, is placed in front
of the wearer's face so as to form the (eye protection) mask.
PRIOR ART
[0005] A unit of the generic type composed of helmet and protective
eye mask is known from WO 2005/070359 A1. The protective eye mask
is securable to the helmet in front of the wearer's face. To this
end, the shape of the protective eye mask is adapted to a
corresponding opening of the helmet. The protective eye mask is
often quite difficult to operate.
[0006] A unit composed of helmet and an eye protection element is
known from US 2006/268220 A1.
[0007] U.S. Pat. No. 6,174,058 B1 discloses an arrangement composed
of a cap and a pair of protective goggles connectable thereto.
[0008] An arrangement comprising a helmet and an eye protection
element is known from subsequently published patent no. EP 2 435
729 A1. Helmet and eye protection element are magnetically
connectable to each other.
[0009] For certain outdoor sports activities, in the industry or on
construction sites, it is known to combine a helmet with a pair of
goggles for protecting the head and the eyes. In order to achieve
an optimum degree of protection, it must be ensured that a perfect
contact is provided between the helmet and the eye protection
element.
[0010] A first prior-art type of helmet is provided with a
transparent visor that is pivotably attached to the front side of
the helmet. A visor of this type is part of the helmet so a person
wearing the helmet is able to move the visor from an active
position of use to an inactive position out of his/her field of
vision by a simple movement of his/her hand. In the position of
use, the distance between visor and face is not adjustable, and the
visor needs to be shaped in such a way as to be adapted to the
rounded profile of the front side of the helmet cap. If the visor
is visible on the front side of the helmet even in the inactive
position, the visor is exposed to influences and scratches that
result in premature wear and, consequently, reduced vision.
Furthermore, if provided with a visible visor, the helmet cannot be
equipped with an additional shield. Such a helmet of the generic
type is for instance known from DE 29 18 587 A1.
[0011] There are also helmets comprising integrated flip-down
visors which are retractable into a gap inside the helmet cap wall
when not in use. The structure of a helmet of this type is however
complicated and the production thereof is very expensive. A helmet
of this type is for instance known from DE 20 2011 101 138 U1.
[0012] A second prior-art type of helmet comprises an eye
protection element which is not integrated into the helmet cap but
forms an individual part. A prior art helmet-goggles combination of
this type is for instance disclosed in DE 10 2004 005 757 A1. The
eye protection element is secured to the helmet by means of an
elastic band that runs around the rear part of the helmet cap or
the wearer's head. An elastic band of this type has the following
disadvantages: [0013] a high contact pressure is exerted on the
face as a result of the elastic force, resulting in excess sweating
and reduced comfort; [0014] when the wearer tries to move the eye
protection element to the inactive position on the upper rounded
part of the helmet cap, the eye protection element may slide back
and fall to the ground, causing the eye protection element to be
damaged; [0015] when the eye protection element is reattached in
the position of use, it is not always possible to find one's
preferred position that was used before, thus requiring additional
adjustment; [0016] the field of vision is limited and insufficient;
[0017] a fastening device must be provided on the back of the
helmet.
Object of the Invention
[0018] An object of the invention is to provide a unit composed of
protective helmet and protective mask (=protective goggles) which
allows the eye protection element to be attached quickly in such a
way as to ensure a good surface-to-surface contact with the face
without excess pressure so that the eye protection element is
easily removable for storing or cleaning.
[0019] The unit composed of protective helmet and protective mask
is characterized in that the upper edge of the eye protection
element is in close contact with the profile of the lower edge on
the front part of the helmet cap, and that a magnetic device is
arranged on both edges for securing the eye protection element to
the helmet cap, wherein the magnetic device comprises a first
series of permanent magnets which are rigidly connected to one of
the two edges and interact, by magnetic attraction, with
complementary elements provided on the opposite edge.
[0020] This ensures that the goggles are securely attached to the
lower edge of the helmet cap so as to prevent draft and--if the
goggles comprise tinted lenses--sunlight from passing through the
goggles. The magnetic connection device, which replaces the
conventional elastic band used for fastening, allows larger goggles
to be used having a very large field of vision.
[0021] The contact pressure exerted on the face by the goggles is
less strong than the contact pressure exerted by conventional
goggles comprising an elastic band, which provides for better
wearing comfort and prevents excess sweating.
[0022] The front magnetic connection area between the two
respective edges comprises means for orienting the tilt of the
goggles in order to adjust the contact with the face. The tilting
means are preferably disposed centrally in the front connection
area, comprising snap-in members and complementary notches for
positioning the goggles so as to allow an adjustment movement about
a tilt axis.
[0023] The eye protection element is preferably configured as
goggles, screen, mask, visor or the like.
[0024] The expression "first series" preferably refers to a first
arrangement.
[0025] "Complementary" elements are elements which are able to
interact, by magnetic attraction, with the permanent magnets
serving as counter elements.
[0026] The complementary magnetic elements may either be formed of
ferromagnetic parts or of a second series of permanent magnets
having a polarity that is opposite to that of the magnets of the
first series.
[0027] The expression "second series" preferably refers to a second
arrangement.
[0028] "Complementary" notches are preferably notches which are
able to interact with the snap-in members.
[0029] According to another embodiment of the invention, the
permanent magnets of the lower edge are disposed in grooves via an
elastic spring system.
[0030] Flexible connection means are advantageously arranged
between the helmet and the goggles to prevent the goggles from
getting lost when not in use.
[0031] The embodiment in which the eye protection element is
fixable, by means of the magnetic device, relative to the helmet
cap in a number of vertical positions on the helmet cap provides a
particularly simple and effective way of adapting the eye
protection element to the wearer's head.
[0032] In a favourable embodiment, the helmet cap comprises an
insert that is provided with the helmet-side part of the magnetic
device, the vertical position of the insert being variable relative
to the other components of the helmet cap. This insert is
preferably guided for displacement along the shell of the helmet
cap between a lower position and an upper position. Preferably, it
is guided for displacement inside the shell.
[0033] The at least one pivot joint arranged between the goggles
and the helmet cap for pivoting the goggles between a position of
use and a storage position is preferably provided with exactly one
pivot joint lever. This pivot joint lever is articulated to the
goggles, preferably to an adjustment member of the goggles, and the
helmet cap. According to an alternative embodiment, the at least
one pivot joint has two pivot joint levers which are in turn
articulated to each other. One of the pivot joint levers is in turn
articulated to the goggles while the other pivot joint lever is
articulated to the helmet cap.
[0034] The at least one face pressure spring element for pressing
the goggles to the wearer's face is preferably arranged between the
goggles and the helmet cap. In a favourable embodiment, the at
least one face pressure spring element is configured as a helical
spring, a coil spring, a torsion bar spring or the like.
[0035] The embodiment which is configured in such a way that in
order to adjust the tilt of the goggles, the upper edge extends
along a pivotably mounted adjustment member of the goggles, the
adjustment member being provided with the goggles-side part of the
magnetic device, provides a particularly secure and simple way of
pivoting the goggles for particularly easy and simple adjustment of
the goggles to the wearer's face. It is advantageous if the
adjustment member is pivotably mounted to the goggles frame of the
goggles or to the upper part of the actual goggles. Alternatively,
the at least one face pressure spring element is arranged between
the adjustment member of the goggles and the remaining part of the
goggles.
[0036] It is advantageous if the adjustment member is securable to
the helmet cap by means of first and second positive locking
members providing an additional positive fit when in the position
of use.
[0037] In a favourable embodiment, the first and second positive
locking members, which in each case interact in pairs, are
configured in such a way that when they are in engagement, the
adjustment member cannot be moved downwardly in the direction of
the upper member of the goggles frame or of the goggles. It is
advantageous if the adjustment member is removable from the helmet
cap only by a forward pivoting movement.
[0038] It is advantageous if the adjustment member is removable
both from the goggles frame or the upper part of the actual goggles
and from the helmet cap.

DETAILED DESCRIPTION OF THE INVENTION
[0056] In the Figures, a unit designated by reference numeral 10
and composed of helmet and protective mask (=protective goggles) is
formed by a shell-shaped helmet cap 11 which is formed so as to
surround the wearer's head and by an eye protection element 12
which is configured so as to be placed in front of the face to
protect the eyes against wind, humidity, cold and sunshine.
[0057] The helmet cap 11 is formed by a rigid shell of a
shock-proof plastic material, in particular of a thermoplastic
material such as ABS, PC, PVC or PET, and a lower shell of a
shock-absorbing material such as EPS, EPP . . . . The helmet cap 11
is provided with a conventional fastening system 13 composed of a
chin strap 13a and a buckle (not shown).
[0058] According to the Figures, the eye protection element 12 of
the goggles is a transparent screen of a low thickness, tinted or
non-tinted, which covers the entire face in the vicinity of the
eyes. It may also have the profile of a pair of goggles (not shown)
comprising a pair of screens or lenses arranged in front of the
eyes. The transparent material of the eye protection element 12 is
extremely shock-proof and preferably unbreakable.
[0059] In the position of use, the eye protection element 12 of the
goggles is secured to the helmet by means of a magnetic device 14
comprising a permanent magnet 15 (FIG. 2).
[0060] Flexible connection means allow the goggles to be secured to
the helmet cap 11, thus preventing the goggles from getting lost
when they are no longer in the position of use on the helmet. These
connection means 16 may consist of a drawstring 17, wherein one end
of which is fastened to the goggles basis while the opposite end
thereof interacts with a roll-up device 18 inside the helmet cap
11, in particular in an area near the wearer's ear. Naturally, any
other retaining band may be used, made for instance of an elastic
or non-elastic material with or without roll-up device.
[0061] The magnetic device 14 according to FIG. 2 consists of a
first row/series of permanent magnets 15 which are arranged at a
distance from one another along the lower edge 19 on the front side
of the helmet cap 11 and interact with complementary elements 20 on
the upper edge 21 of the eye protection element 21 by magnetic
attraction.
[0062] These complementary elements 20 may be configured as
follows: [0063] as ferromagnetic elements which are attracted by
the magnetic field of the permanent magnets 15 when the goggles are
moved closer in the direction of the lower edge 19 of the helmet
cap 11. It is conceivable as well for the permanent magnets 15
along edge 19 to be interchanged with the complementary elements 20
along edge 21. [0064] as a second row/series of permanent magnets
the polarity of which is opposite to that of the first row, the
opposite poles resulting in an increased magnetic attraction and
centring effect.
[0065] The pole surfaces of the permanent magnets 15 and the
contact surfaces of the complementary elements 20 they come into
contact with are preferably plane for optimized attraction.
[0066] The upper edge 21 of the eye protection element 12 is
exactly adapted to the shape of the lower edge 19 of the front part
of the helmet to prevent gaps in the magnetic connection area. As a
result, the goggles are securely fastened to the lower edge 19 of
the helmet cap 11 while ensuring a good protection against draft
and, if it is a pair of goggles comprising tinted lenses, against
sunlight.
[0067] In the embodiment as shown in FIGS. 3 and 4, the front
magnetic connection area is formed between the two respective edges
19 and 21 of the helmet and of the goggles to allow the eye
protection element 12 of the goggles to be tilted in the direction
of arrow F. In this manner, the contact with the face can be
optimally adjusted, regardless of the shape of the wearer's
face.
[0068] The central area of the lower edge 19 has a concave or
convex shape and comprises positioning snap-in members 22 for
adjusting the tilt of the goggles about the tilt axis XX'. The
upper edge 21 of the goggles is preferably provided with notches 23
which interact with one of the snap-in members 22 in a selected
position of tilt. In this central area, a permanent magnet 15 may
be inserted opposite a complementary magnetic element 20. Two other
lateral areas are disposed next to the central area, comprising
permanent magnets 15 and complementary magnetic elements 20 for
retaining the goggles by applying a slight amount of pressure on
the face.
[0069] Furthermore, the peripheral inner wall of the goggles is
coated with a foam layer 24 that ensures a pleasant and close
contact with the face.
[0070] In the embodiment according to FIG. 2, particular permanent
magnets 15 are accommodated in the lateral areas in grooves 25 of
the lower edge of the helmet via a spring 26 or another elastic
system. This increases the range of tilt adjustment while the
pressure applied on the face remains the same.
[0071] Since no elastic belt is provided for fastening, a larger
pair of goggles can be used that has a very large field of
vision.
[0072] The goggles are put on and off as follows:
[0073] In order to put the goggles on, it is sufficient to move the
eye protection element 12 into the vicinity of the lower edge 19 of
the helmet cap 11. The magnetic attraction exerted by the permanent
magnets on the complementary magnetic elements 20 causes the
goggles to abut against the lower edge 19. This results in a stable
surface-to-surface contact with the face so that a good protection
of the eyes against wind, humidity, cold and--if the lenses are
tinted--against sunlight is achieved. Furthermore, the possibility
of adjusting the tilt of the goggles provides for better wearing
comfort. Contact pressure is less strong than that exerted by
conventional goggles comprising an elastic band, which provides for
better wearing comfort and prevents excess sweating.
[0074] In order to take off the goggles, the goggles are slightly
pivoted upwardly in a bottom-to-top movement, causing the
complementary elements 20 to be separated from the permanent
magnets 15 at oblique angles. As a result, a gap in the shape of a
dihedron is obtained which causes the magnetic attractive forces to
be greatly reduced, resulting in a quick separation of the
complementary elements 20.
[0075] If the goggles are in the separated position (FIG. 5), the
provided drawstring 17 of the connection means 16 ensures that:
[0076] the goggles may dangle from the helmet along the front side
of the upper part of the body and cannot get lost; [0077] the
goggles are easily accessible for cleaning; [0078] they may be
stored underneath the jacket for protection.
[0079] The drawstring 17 may have two different lengths, one
shorter length in a position of use of the goggles and another full
length when the goggles are not in use (inactive position).
[0080] The following is a description, with reference to FIGS. 6 to
9, of another embodiment of the invention. In contrast to the
previous embodiment, the unit composed of helmet and goggles
according to this embodiment comprises an adapter-like adjustment
member 27 that is configured in the manner of a web or a bracket.
The adjustment member 27 is a component of the eye protection
element 12. It has an elongated shape, extending--when
mounted--above an upper rim 28 of the actual goggles or of a
goggles frame of the goggles. The upper edge 21 of the goggles
extends along the adjustment member 27.
[0081] The adjustment member 27 has two opposite ends 29. Each end
29 of the adjustment member 27 is provided with at least one
complementary element 20. Alternatively, the complementary elements
20 are provided at a distance from the ends 29 of the adjustment
member 27. It is advantageous if the shape of the adjustment member
27 is substantially adapted to the respective shape of the upper
rim 28 of the goggles.
[0082] A first positive locking means 30 is arranged between the
two complementary elements 20 on top of the adjustment member 27 of
the goggles which positive locking means 30 is configured as a
retainer that is upwardly open in the direction of the edge 19.
When mounted, the first positive locking means 30 is rearwardly
open in the direction of the inner space of the helmet cap 11. It
is advantageous if the first positive locking means 30 is arranged
centrally between the complementary elements 20.
[0083] The adjustment member 27 is further provided with two first
pivot bearing members 31. It is advantageous if the first pivot
bearing members 31 are provided between the complementary elements
20 or opposite the first positive locking means 30. According to
FIGS. 8 and 9, the first pivot bearing members 31 are configured as
bearing retainers. In a favourable embodiment, the first pivot
bearing members 31 are arranged on the lower side of the adjustment
member 27.
[0084] Two second pivot bearing members (not shown) are provided on
the upper rim 28 of the goggles or on top of the goggles frame. The
second pivot bearing members are complementary to the first pivot
bearing members 31. They are in each case formed by aligned pivots
which define the tilt axis XX' and extend in the width direction of
the goggles.
[0085] When the adjustment member 27 is mounted, the first and
second pivot bearing members 31 combine in pairs to form respective
pivot bearings each providing an articulated connection. The
goggles are thus pivotable to the front and to the back about the
tilt axis XX'.
[0086] The lower edge 19 of the front side of the helmet cap 11 is
provided with a second, helmet-side positive locking means 32 which
is complementary to the first positive locking means 30. According
to FIG. 8, the second positive locking means 32 is configured as a
pin that is arranged between the permanent magnets 15. It protrudes
downwardly from the lower edge 19.
[0087] When the permanent magnets 15 are in magnetic interaction
with the complementary elements 20, the first and second positive
locking means 30, 32 are in a positive locking engagement as well,
thus providing an additional way of securing the adjustment member
27 to the helmet cap 11. The positive locking means 30, 32 are
arranged and configured in such a way as to be engageable with each
other automatically when the permanent magnets 15 and the
complementary elements 20 are moved towards each other.
[0088] The first and second positive locking means 30, 32
interacting in pairs are configured in such a way that when they
are in engagement, the adjustment member 27 cannot be removed from
the helmet cap 11 in a downward direction towards the upper part of
the goggles frame or the goggles rim 28. The adjustment member 27
is only removable from the helmet cap when pivoted forward. The
first positive locking means 30 is backwardly open. It is
configured in the manner of a keyhole. The second positive locking
means 32 is furthermore provided with an outwardly open retaining
groove 33 which extends along at least a portion of its peripheral
region and which is positively engaged by a corresponding web of
the first positive locking means 30 when the first and second
positive locking means 30, 32 are in a positive locking engagement.
It is advantageous if the first positive locking means 30 is
provided with projections that can be overcome, the projections
preventing the adjustment member 27 from being undesirably pivoted
away from the second positive locking means 32.
[0089] According to an alternative embodiment, the first and second
positive locking means 30, 32 are interchanged with each other.
According to an alternative embodiment, the first and second pivot
bearing members 31 are interchanged with each other.
[0090] According to FIG. 10, at least one face pressure spring
element 32 is arranged on at least one of the adjustment member
pivot bearings. The at least one face pressure spring element 34 is
arranged on the at least one first and/or second pivot bearing
member 31 so as to press the goggles 12 against the face of the
wearer when the unit composed of helmet and goggles is in use.
[0091] According to FIG. 11, the adjustment member 27 is
furthermore latched with the goggles. The at least one first and/or
second pivot bearing member 31 is provided with corresponding latch
elements 34a and/or counter latch elements 34b, respectively.
Alternatively, the at least one first and/or second pivot bearing
member 31 is allocated to corresponding latch elements 34a or
counter latch elements 34b, respectively.
[0092] According to FIG. 12, the helmet cap 11 comprises an insert
35 that is guided on the shell of the helmet cap 11 for
displacement between an upper position and a lower position. The
insert 35 is manually operable from outside via a handle 36. The
permanent magnets 15 are arranged on the insert 35. The permanent
magnets 15 are thus height-adjustable.
[0093] The complementary elements 20 are arranged on the goggles
and interact with the height-adjustable permanent magnets 15. The
complementary elements 20 may be arranged on the adjustment member
27 or directly on the goggles frame or the goggles rim 28,
respectively. The height adjustability of the permanent magnets 15
ensures that the goggles are height-adjustable relative to the
helmet cap 11 as well. The higher the position of the permanent
magnets 15, the higher the position of the goggles. The lower the
position of the permanent magnets 15, the lower the position of the
goggles.
[0094] According to FIGS. 13 to 15, the ends of the adjustment
member 27 are in each case provided with a pivotably mounted pivot
joint lever 37. The pivot joint levers 37 are furthermore pivotably
mounted to the goggles frame. Alternatively, they are pivotably
mounted to the goggles and to the helmet cap 11. The pivot joint
levers 37 combine with the allocated pivot points to form pivot
joints. The pivot joint levers 37 ensure a guided displacement of
the goggles from their position of use into their upper storage
position. In the storage position, the actual goggles are
physically separated from their adjustment member 27 which remains
in magnetic connection with the lower edge 19 of the helmet cap
11.
[0095] In FIG. 13, the goggles are in their position of use. They
adjoin the front lower end of the helmet cap 11 and are
magnetically secured thereto via the magnetic device 14. The pivot
joint levers 37 are in a first position. When the goggles are
displaced from their position of use into their upper storage
position, the pivot joint levers 37 are pivoted as well. When they
are pivoted into the storage position, the goggles are also moved
forward by the pivot joint levers 37. In the storage position, the
goggles abut against the outer front side of the helmet cap 11. The
pivot joint levers 37 are then in a second position. As mentioned
at the outset, the goggles may be replaced by a screen, visor a
mask or the like.
[0096] According to FIG. 16, each side of the goggles is provided
with a pivot joint in the form of an elbow joint. Each pivot joint
has a first and second pivot joint lever 38, 39 which are in turn
articulated to each other. The first pivot joint levers 38 are
articulated to the helmet cap 11. The second pivot joint levers 39
are articulated to the goggles.
[0097] In FIG. 16, the goggles are shown in their position of use
in which they are magnetically secured to the helmet cap 11 by
means of the magnetic device 14 and abut against the lower front
side of the helmet cap 11. When the goggles are pivoted to their
storage position, the goggles are also displaced forward relative
to the helmet cap 11. In the storage position, the goggles are
arranged adjacent to the outer front side of the helmet cap 11.
When the goggles are pivoted, the position or orientation of the
pivot joint levers 38, 39 changes as well. As mentioned at the
outset, the goggles may be replaced by a screen, visor, a mask or
the like.
