Description
[0001] This Continuation Application is based U.S. application Ser.
No. 16/271,722 filed Feb. 8, 2019 by Torben Skov and Roman Skov,
inventors, for Safety Glasses for a Human User.
BACKGROUND OF THE INVENTION
[0002] The invention relates to safety glasses for a human user,
with at least one lens which has an upper rim assignable to the
user's forehead and a lower rim assignable to a user's cheek, with
at least one nosepiece arranged at the lens and with at least one
protective lip to be supported on the user's face.
[0003] Furthermore, the invention relates to a safety system for a
human user, the safety system having safety glasses and a
respiratory mask which are configured separately and can be handled
separately.
PRIOR ART
[0004] There are already known prior art safety glasses and safety
systems. Safety glasses serve to protect a user's eyes against
dust, chips, liquid, temperature or other products which are, in
particular, produced while a work piece is being machined and which
may be hurled towards the user. Typically, safety glasses have one
lens or two lenses which are made of a transparent material and
have the refractive index of a conventional glass pane and are
therefore not able to impair the user's optics. As a matter of
course, however, safety glasses having lenses with a refractive
index adjusted to the user are also available.
[0005] In order to ensure that the eyes are sufficiently provided
with oxygen while the safety glasses are worn and the lenses are
prevented from becoming steamy, the lenses are usually kept spaced
apart from the user's eyes and face. To achieve this, a nosepiece
is usually provided which is permanently fixed to the lenses and
positions the lenses on the user's nose such that there remains a
distance to the user's eyes and the user's face, respectively.
Since, in this case, the aforementioned products may nevertheless
enter into the vicinity of the user's eyes between the outer rim of
the respective lens and the user's face, it is known to bridge this
distance by means of a protective lip.
[0006] For example, the patent specification EP 2 215 997 B1
discloses safety glasses of the generic type which have a
continuous lens for both of the user's eyes as well as a protective
lip which extends across the entire rim or the outer perimeter of
the lens and thereby covers the area between the user's face and
the lens in its entirety, so that the aforementioned products
cannot enter into the vicinity of the user's eyes. In order to
provide the user with sufficient oxygen nevertheless, the
protective lip has a plurality of openings. Therein, the protective
lip extends from the lateral rim of the lens directly towards the
user's face and therefore essentially projects towards the user at
a right angle with respect to the lens. As a result, the user's
sight is impaired to as small an extent as possible and the space
the safety glasses require on the user's face is minimised. This
ensures both wearing comfort and protective effect.
[0007] In interaction with respiratory masks, however, this may
cause the problem that the space between the safety glasses and the
respiratory mask is not sufficient to ensure that the user can wear
both elements in a convenient/comfortable manner. More
particularly, this may cause that, in use, the respiratory mask and
the safety glasses constantly or temporarily clash with each other.
Apart from impaired convenience for the user, this may result in
the protective lip detaching from the user's face, for example, due
to movements of the safety glasses.
[0008] The invention is therefore based on the object to create
improved safety glasses which, particularly in interaction with a
respiratory mask, improve the user's convenience while they
simultaneously ensure that the user's eyes are protected against
harmful products.
OBJECT OF THE INVENTION
[0009] The object the invention is based on is achieved by safety
glasses having the features of claim 1. These safety glasses are to
advantage in that their beneficial configuration ensures high user
comfort as well as high operational safety and that the integration
of a respiratory mask into the safety system that is formed by the
safety glasses and the respiratory mask is achieved easily and
without any difficulty. The space available on the user's face is
used optimally and dirt particles are reliably prevented from
reaching the user's eyes. To achieve this, it is provided according
to the invention that the protective lip only extends at a lower
rim of the lens from the nosepiece towards at least one lateral rim
of the lens and, in prolongation of the lens, downwards from the
lower rim of the lens to be supported on the user's cheek. Due to
the fact that the protective lip essentially extends only at the
lower rim of the lens, at least the upper rim area of the glasses
is free from the sealing lip and allows an exchange of oxygen
and/or air and prevents the lens from becoming steamy. Due to the
fact that the protective lip, in prolongation of the lens, extends
downwards away from the lower rim of the lens to be supported on
the user's cheek, and does not vertically extend from the lens
directly to the face, as has been customary so far, the resulting
protective lip flatly covers the user's cheek and extends towards
the area where, otherwise, a respiratory mask is arranged. Therein,
the respiratory mask can be optionally placed on the protective
lip, with the result that the protective lip and the respiratory
mask overlap each other and that, firstly, the user's face and eyes
are reliably protected and that, secondly, a reliable support of
the protective lip on the user's face on the one hand, and of the
respiratory mask on the user's face on the other hand, are ensured,
in the latter case with interposition of the protective lip. The
protective lip extends the lens downwards all the way to the user's
cheek, with the result that the user and, more particularly, the
user's eyes are reliably and constantly protected. In addition, the
beneficial configuration of the safety glasses ensures that the
lens can be arranged particularly close to the user's face. Due to
the fact that the protective lip does not extend vertically from
the lens toward the user's face but extends downwards in
prolongation of the lens, the distance between the lens and the
user's face can be minimised. This is, on the one hand, to
advantage in that, for example, an air gap between the user's face
and the lens is minimised in a section that is free from the
protective lip, thus further increasing the user's safety and that,
on the other hand, the risk of collision with a respiratory mask,
possibly used at the same time, is reduced. Since the lens is
arranged close to the user's face, additional space is created for
the respiratory mask, with the result that the user can wear both
the respiratory mask and the safety glasses in a comfortable and
reliable manner.
SUMMARY OF THE INVENTION
[0010] According to a preferred refinement of the invention, it is
provided that the safety glasses only have one continuous lens to
protect both of the user's eyes and that the protective lip only
extends at a lower rim of the lens from the nosepiece towards each
of both lateral rims of the lens. This results in simple and
compact safety glasses which can be produced in a cost-efficient
manner and, since they comprise only a few component parts, ensure
easy handling.
[0011] According to an alternative embodiment of the invention, the
safety glasses have a separate lens for each of the user's eyes,
wherein the nosepiece is connected to both lenses, and each case a
protective lip only extends at a lower rim of each lens from the
nosepiece towards the outer lateral rim of the respective lens. The
safety glasses thus have two protective lips or protective lip
parts each of which extends from the nosepiece to the lateral rim
of the respective lens, i.e., along the lower rim and to the outer
rim of the respective lens. This provides the user with the same
protection and allows achieving the same advantages as described
above. Depending on the production method, the production of the
safety glasses is more cost-efficient because two separate lenses
are provided, and it allows higher flexibility in adjusting the
safety glasses to the user's face.
[0012] According to a preferred embodiment of the invention, the
respective protective lip, i.e., said continuous one with a
continuous lens or the two protective lips or protective lip parts
with two lenses, is configured to be flatly supported on the user's
cheek. This flat support improves the wearing comfort and optimises
the sealing effect. Furthermore, this results in the protective lip
having a large support surface for the respiratory mask.
[0013] In addition, the respective protective lip preferably has a
curvature in its downward extension so that it is flatly supported
on the user's cheek. As a result of the curvature, the shape of the
protective lip is adjusted to the face and allows a comfortable and
reliable, more particularly a sealing contact with the user's
face.
[0014] Preferably, the lens has a convex curvature and the
curvature of the respective protective lip is concave at least in
certain sections. This results in an S-shaped contour of the safety
glasses formed by the lens and the protective lip. This contour
ensures, on the one hand, a beneficial support on the user's face
by means of the protective lip and, on the other hand, a beneficial
protection of the user's eyes.
[0015] In particular, the respective protective lip is formed
integrally with the nosepiece. In the final analysis, this results
in a continuous protective lip for the safety glasses, irrespective
of whether the safety glasses have one lens or two lenses. In the
vicinity of the nose, the protective lip is only interrupted by the
shape of the nosepiece.
[0016] Preferably, the continuous protective lip contributes to
forming the nosepiece. As a result, the nosepiece has a shape which
corresponds to the shape of the protective lip. The beneficial
configuration of the protective lip results in an automatically
advantageous nosepiece which rests on the side facing away from the
user's face. This results in the additional advantage that the
safety glasses can be arranged particularly close to the user's
face. This reduces the distance between the lenses or the lens and,
for example, the user's forehead to a minimum, with the result that
dirt particles are also prevented from penetrating at that point
and, at the same time, an exchange of air is ensured to prevent the
lenses from becoming steamy and/or to provide the eyes with
oxygen.
[0017] Preferably, the nosepiece is, at least essentially, arranged
on the side of the safety glasses facing away from the user's face.
In this case, this is particularly irrespective of whether the
protective lip contributes to forming the nosepiece or whether the
nosepiece is formed integrally with or separately from the
protective lip. This results in the already aforementioned
advantage with respect to the minimised distance between the lens
or the lenses and the user's forehead.
[0018] Furthermore, it is preferably provided that the respective
protective lip is configured such that it can be elastically
deformed. This results in a high wearing comfort and a reliable
seal even in case of different face shapes. Furthermore, the
respective protective lip preferably has a thickness that decreases
towards the end facing away from the lower rim of the lens. As a
result, the protective lip, for example, is tapered and
facilitates, for example, supporting a respiratory mask.
[0019] According to a preferred refinement of the invention, the
respective protective lip has a mask support surface facing away
from the user, wherein a respiratory mask for the user can be
supported on said mask support surface. Due to the mask support
surface, the protective lip, for example, extends farther across
the user's cheek than it would be necessary for the actual sealing
function, This, however, ensures that the respiratory mask can be
reliably supported on the protective lip and that the beneficial
interaction between the respiratory mask and the protective lip is
achieved as has already been illustrated above.
[0020] Preferably, the mask support surface has a sliding surface
in order to enable relative movements between the respiratory mask
and the safety glasses. To achieve this, the sliding surface is
preferably adjusted to the material and/or the surface structure of
the respiratory mask in order to ensure a frictional resistance
that is as low as possible. This ensures that, in use, the safety
glasses are prevented from being displaced in case the respiratory
mask gets out of place. Furthermore, this ensures that a movement
of the respiratory mask does not eliminate the sealing effect
between the safety glasses and the user's face.
[0021] According to a preferred refinement of the invention, the
respective protective lip is, at least essentially, configured
transparent. As a result, the protective lip also extends the lens
in its function, so that the user can look down even through the
protective lip.
[0022] Preferably, the respective protective lip is shaped to fit
to the respective lens, particularly in a substance-to-substance
bond. This ensures an integral formation of the protective lip on
the lens and easy handling as well as simple assembly. This
particularly prevents that the protective lip can be detached from
the lens during use.
[0023] The safety system according to the invention having the
features of claim 15 is characterised by the configuration of the
safety glasses according to the invention. This results in the
already aforementioned advantages. According to a first embodiment,
the respiratory mask and the safety glasses are configured such
that, when being used, the respiratory mask is supported on the
protective tip of the safety glasses at least in certain regions,
wherein the protective lip preferably has the already
aforementioned mask support surface. According to a further
embodiment, the safety glasses and the respiratory mask are
configured to rest on the user's face side by side, with the result
that there will be no overlapping/crossover. As a result, the
safety glasses and the respiratory mask each separately rest
against the user's face in a sealing manner. Due to the beneficial
configuration of the safety glasses, there is enough space
available for the respiratory mask, with the result that the
respiratory mask, if displaced by the user, is prevented from
hitting against the safety glasses and thus from impairing the
sealing effect, and vice versa.
BRIEF DESCRIPTION OF THE DRAWING
[0024] Other advantages and preferred features and feature
combinations particularly result from the above description and
from the claims. The invention will now be illustrated in more
detail below by means of the drawing. In the drawing,
[0025] FIG. 1 is a perspective and simplified view of safety
glasses for a human user,
[0026] FIG. 2 is a first sectional view of the safety glasses of
FIG. 1, and
[0027] FIG. 3 is a second sectional view of the safety glasses of
FIG. 1,
[0028] FIG. 4 is a view of a further embodiment of the safety
glasses with box diagrams representing two separate lenses.
DETAILED DESCRIPTION OF THE INVENTION
[0029] FIG. 1 is a simplified perspective view of safety glasses 1
that are configured to be used by a human user. To achieve this,
the safety glasses 1 have a lens 2 that is configured to cover both
of a user's eyes. The lens 2 thus has two lens sections 3, wherein
each lens section 3 can be assigned to one of the user's eyes.
Between the lens sections 3, the safety glasses 1 have a nosepiece
4 which serves to support the safety glasses 1 on the user's nose
and to position them on the face. The nosepiece 4 will be
illustrated in more detail below. The nosepiece 4 thus rests
centrally at the lens 2. The lens 2 has an upper rim 5 that can be
assigned to a user's forehead, a lower rim 6 that can be assigned
to the user's nose and cheeks, with the nosepiece 4 being assigned
to said lower rim 6, as well as two outer lateral rims 7 connecting
the upper rim 5 to the lower rim 6. In addition, a temple 8
extending backwards from the lens 2 and towards the user's face is
assigned to each of the outer lateral rims 7. The temples 8 are
thus assigned to the rear side 9 of the lens 2.
[0030] Furthermore, the safety glasses 1 have a protective lip 10
that is assigned to the lower rim 6 of the lens 2. According to the
present exemplary embodiment, the protective lip 10 extends almost
across the entire lower rim 6 of the lens 2. Therein, the
protective lip 10, at least essentially, extends across both lens
sections 3 to near the respective lateral rim 7. Depending on the
exemplary embodiment, the remaining distance from the lateral rim 7
can be selected larger or smaller in size, in addition, the
protective lip 10 can also extend to the lateral rim 7 or beyond
the latter if necessary. Due to the fact that the protective lip 10
also extends across the central area of the lens 2, the protective
lip 10 extends across the nosepiece 4. According to the present
exemplary embodiment, the protective lip 10 is configured such that
it forms the nosepiece 4.
[0031] FIG. 2 is a first sectional view of the safety glasses 1 of
FIG. 1 along line A-A. The section thus rims approximately
centrally through a lens section 3. The protective lip 10 is
affixed to the lower rim 6. To achieve this, the protective lip 10
is, in particular, injection-moulded onto the rear side 9 of the
lens 2, with the result that a substance-to-substance bond is
produced between the protective lip 10 and the lens 2. While the
lens 2 itself is configured transparent as is customary, the
protective lip 10 can alternatively be made of a non-transparent
material. According to the present exemplary embodiment, the
protective lip is also made of a transparent material. Optionally,
the protective lip 10 can also be made of a non-transparent
material.
[0032] In particular, the protective lip 10 is configured such that
it is elastically deformable; in its unloaded or
non-deformed/neutral state, however, it has a curvature 11. On the
one hand, the protective lip 10 is curved in its course along the
lens 2 because it extends along the rim 6 on the lens 2. On the
other hand, the curvature 11 of the protective lip 10 extends, as
seen in cross-section, from the lens 2 down to the lower rim 6 of
said lens 2. The protective lip 10 is configured such that it first
follows the course of the lens 2 and finally prolongs the lens 2 at
its lower rim 6. While, according to the present exemplary
embodiment, the lens 2 is convex as seen from above, the protective
lip 10 is concave due to the curvature 11, with the result that the
lens 2 and the protective lip 10 result in an S-shape. Due to its
advantageous design, the protective lip 10 is suitable to be
supported on the user's cheek. In particular, the curvature 11
ensures a comfortable flat support of the protective lip 10 on the
cheek which, on the one hand, ensures a high wearing comfort of the
safety glasses 1 for the user and, on the other hand, a reliable
seal between the lens 2 and the user's face, said seal, for
example, preventing chips from reaching the user's eyes when work
pieces are being machined. The protective lip 10 is configured such
that it is elastically deformable, with the result that it
advantageously adjusts to different face shapes and in any case
provides a comfortable and reliable seal. While, according to the
present exemplary embodiment, the protective lip 10 has a
continuously constant thickness d, it is provided according to a
further exemplary embodiment not presented here that the thickness
d of the protective lip 10 decreases towards the free end 12 facing
away from the lower rim 6 of the lens 2. This increases the
flexibility of the protective lip 10 at its free end and even
further improves the wearing comfort. Due to the filet that the
protective lip 10 extends downwards in prolongation of the lens 2,
the lens 2 furthermore can be arranged particularly close to the
user's face; this ensures that an air gap between the lens and the
user's face is minimised and that, thereby, dust or chips are
prevented from entering into the area between the lens and the
face, and that there is more space available for a respiratory mask
on the user's face, with the result that, in particular, the
respiratory mask and the safety glasses 1 are prevented from
abutting against each other while they are in use and thereby, for
example, from impairing the tightness of the safety glasses 1 or
the respiratory mask on the user's face.
[0033] Furthermore, the protective lip 10 optionally has a mask
support surface 14 on its front side 13 facing away from the user's
face, particularly in the vicinity of the five end 12, wherein a
support rim 15 of a respiratory mask 16 (shown with dashed lines)
can be supported on said mask support surface 14. This allows an
overlapping arrangement of the respiratory mask 16 and the safety
glasses 1, said arrangement, on the one hand, ensuring the reliable
protection of the user's eyes by means of the protective lip 10
and, on the other hand, allowing a relative movement between the
safety glasses 1 and the respiratory mask 16, with the result that
a movement of the safety glasses 1 or the respiratory mask 16
during use does not also result in a movement of the respiratory
mask 16 or the safety glasses 1, respectively. Furthermore, the
seal between the protective lip 10 and the user's face is
maintained even if the respiratory mask is displaced, with the
result that the operational reliability is maximised. The safety
glasses 1 and the respiratory mask 16 therefore form a safety
system 17 for the human user, said safety system 17, on the one
hand, ensuring a high wearing comfort and, on the other hand, high
operational reliability. In case of movements of the face and, more
particularly, the mouth, the respiratory mask 16 also moves where
applicable in order to ensure tight seating. The advantageous
combination with the safety glasses 1 prevents the safety glasses 1
from also being moved or displaced thereby. In particular, the mask
support surface 14 has a low roughness which ensures a low
frictional adhesion between the respiratory mask 16 and the
protective lip 10, with the result that an easy relative movement
is enabled. Therein, the mask support surface 14 can form a section
of the protective lip 10 or its surface that is different from the
remaining protective lip 10. As an alternative, the protective lip
10 as a whole has the same surface properties as on the mask
support surface 14.
[0034] While, according to the present exemplary embodiment, the
protective lip 10 is only affixed to the rear side 9 of the lens 2,
the protective lip 10 is, according to a further exemplary
embodiment which is shown by dashed lines in FIG. 2, applied, more
particularly injection-moulded, both to the rear side 9 and to the
front side facing away from the user, in order to ensure that the
protective lip 10 is reliably held to the lens 2 even in case of
higher loads.
[0035] FIG. 3 is a second sectional view of the safety glasses 1
along Line B-B of FIG. 1 extending through the centre of the lens
2, with the result that the nosepiece is also visible in the
sectional view of FIG. 3.
[0036] In the vicinity of the nosepiece 4, the protective lip
10--due to its concave curvature 11 which optionally is stronger in
the vicinity of the nosepiece 4 than in the vicinity of the lens
sections 3 even in the relaxed state of the protective lip
10--extends almost vertically forward from the lens 2, i.e., away
from the user's face, at least when being in use. As a result, the
protective lip 10 itself forms the nosepiece 4 on its rear side 18
that is facing the user. Additional means for providing a nosepiece
4 are therefore not necessary. On the one hand, the shape of the
protective lip 10 in FIG. 3 can result from placing the safety
glasses 1 onto the user's nose or, on the other hand, be already
provided by the deformation of the protective lip 10, for example,
in order to increase the wearing comfort. As a result, the
nosepiece 4 is, advantageously, configured integrally with the
protective lip 10.
[0037] According to an alternative exemplary embodiment that is not
shown here, the nosepiece 4 can also be configured separately from
the protective lip 10 or from two protective lips 10 each extending
across one of the lens sections 3.
[0038] According to a further exemplary embodiment, it is provided
that the lens sections are each formed by two separate lenses 2,
with the result that one lens 2 is assigned to each of the user's
eyes. In this case, the lenses 2 are then, for example, held
together by the nosepiece 4.
[0039] Due to the fact that the nosepiece 4 extends forward away
from the user's face, the respective lens 2 can be arranged
particularly close to the user's face, with the result that, for
example, the distance between the upper rim 5 of the lens 2 and the
user's forehead is minimised as well, whereby it is ensured that
the user's eyes are protected, for example, against chips at this
point as well.
[0040] The integrated configuration of the protective lip 10 and
the nosepiece 4 results in particularly compact safety glasses 1
that can be produced cost-efficiently and handled easily, said
safety glasses 1 providing the aforementioned advantages,
particularly in the safety system 17 in cooperation with the
respiratory mask 16. Furthermore, the advantageous protective lip
10 allows achieving that the lens 2 as a whole can have a lower
height than has been customary with previous safety glasses which
seek the protection at the lower rim 6 by means of a lens 2 that
extends downwards particularly far. In the case of standard safety
glasses, however, this rim is comfort-restricting and cannot be
flexibly adjusted to the user's face. The present beneficially
configured safety glasses 1 allow providing a variety of users with
comfortable reliable protection by means of only one pair of safe
glasses 1. The narrower lens 2 also increases the space for the
respiratory mask 16 and thereby simplifies combinations of
different respiratory masks.
[0041] FIG. 4 shows a further embodiment of the safety glasses 1.
FIG. 4 is a view of this further embodiment of the safety glasses
with box diagrams representing two separate lenses. In contrast to
the above described embodiment with only one lens 2 that has two
lens sections 3, the lens 2 of FIG. 4 is divided into two separate
lenses, one for each lens section 3.
