Description
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention relates to helmet face protectors and more particularly to attachments for releasably securing a transparent shield to a wire grid face protector, and the wire grid face protector to a helmet.
(b) Description of Prior Art
Protective helmets are used in sports such as hockey to protect the wearers from head injuries caused by impacts.
Face protectors attachable to hockey helmets are known. Such face protectors generally consist of a wire grid which substantially covers the face of the wearer. The grid defines a plurality of apertures sufficiently small to prevent passage of hockey sticks and pucks. A large, elongated sight opening is found in the grid and extends in front of the wearer's eyes not to obstruct the wearer's field of vision. A curved, resilient transparent shield of molded high impact resistant plastic material is generally attached to the grid to cover the sight opening and protect the wearer's eyes without hindering the wearer's field of vision.
Different fastening means have been used to secure wire grids to helmets and to fasten shields to wire grids. For example, U.S. Pat. No. 4,031,564 issued to Wood on Jun. 28, 1977 describes a protective face mask including a resilient transparent shield and a wire grid. The shield is provided with tabs at opposed ends thereof bearing outwardly extending projections, to secure to the wire grid at each end of the elongated sight opening of the grid. The shield is flexed to allow insertion of the tabs into grid receptacles to engage the projections thereon. A mounting plate having bolt holes is also secured to the wire grid by fasteners.
A disadvantage of such an attachment is that the shield can be accidentally dislodged upon impact on a side of the helmet. Another disadvantage is that the wire grid can not be quickly and easily removed from the helmet.
U.S. Pat. No. 4,587,677 issued to Clement on May 13, 1986 describes an attachment system for attaching a face mask having a wire grid to a helmet using a hinge and a snap-fit connection. The hinge has two resilient halves integrally hinged together and having a cavity for receiving a wire of the grid. The hinge is retained in a slot in the forehead region of the helmet by the resilient action of the clip halves. The snap-fit connection consists of two vertical slots integrally formed in either side of the helmet and open at the bottom for receiving tabs vertically extending from either side of the face mask. Each tab has two side portions between which is integrally formed a resilient, angulated, outwardly extending tongue connected to the side portions at the upper corners thereof. The tab is retained in the slot by the outward position of the tongue, and is released therefrom by inwardly pressing on the tongue and by pushing the tab downwardly. However, the face mask does not provide a transparent shield which is detachable from the wire grid.
U.S. Pat. No. 4,856,100 issued to Desy et al. on Aug. 15, 1989 describes a face shield detachably connected to a visor. The visor defines a recess in the lower edge thereof to receive the upper edge of the face shield, and has inwardly extending star-shaped detents integrally molded at either side thereof and a wedge-shaped detent integrally molded at the front thereof to correspond with through-holes in the face shield, to receive and engage the detents.
It would therefore be highly desirable to provide an attachment for connecting a transparent shield to a wire grid that would be resistant to dislodgment, that would be removably attachable to the transparent shield and to the wire grid face protector and that would also render the transparent shield quickly releasable and attachable to and from the wire grid face protector.
It would also be highly desirable to provide an attachment for connecting a wire grid to a helmet that would allow the wire grid to be quickly swung away from the face of the wearer, and which could also be easily and quickly secured and removed from the helmet.
SUMMARY OF THE INVENTION
One feature of the present invention is to provide an attachment for connecting a transparent shield to a wire grid which is resistant to dislodgment and which is removably attachable to the wire grid face protector by quick release connectors.
Another feature of the present invention is to provide an attachment for securing a wire grid to a helmet which allows the wire grid to be quickly swung away from the face of the wearer and which is easily and quickly secured and removed from the helmet.
In accordance with the above-mentioned features, from a broad aspect, the present invention provides a clip for releasably securing a transparent shield to a wire grid face protector. The clip comprises a retaining body adapted to be secured to a wire grid face protector at a predetermined location and on opposed sides of a sight opening formed in the wire grid face protector. The retaining body has a guide slot adapted to receive therein an attachment flange of a transparent shield. An opening is formed in an outer wall of the body and configured to receive in abutting engagement a resilient, outwardly inclined tongue of the attachment flange. The transparent shield is disconnectable from the retaining body and hence the wire grid face protector by inwardly depressing the tongue in the opening and by pulling the tongue out of the slot.
The retaining body may be releasably secured to the wire grid face protector by engaging wire members of the grid in opposed channels defined in opposed edges of the clip.
In accordance with another broad aspect, the present invention also provides a wire grid face protector in combination with the above-described clip for releasably securing a transparent shield over a sight opening formed in the wire grid face protector.
In accordance with a further broad aspect, the present invention provides a bracket for releasably securing a wire grid face protector to the forehead region of a helmet. The bracket comprises a body adapted for securement to the helmet and forming a groove into which a wire member of the wire grid face protector is releasably and frictionally retained. A wire member of the wire grid face protector is disposed at a predetermined location and adapted to snap-fit into the bracket.
In accordance with a still further broad aspect of the present invention, there is provided a transparent shield which is releasably securable to a wire grid face protector. The transparent shield comprises securement means for releasably securing the transparent shield to the wire grid face protector. The securement means is constituted by attachment flanges disposed at opposed ends of the transparent shield and adapted for insertion into a clip which is secured to the wire grid face protector. The flanges have a resilient, outwardly inclined tongue configured to abuttingly engage in an opening of the clip.
The attachment flange and tongue may be integrally formed with the transparent shield.
The tongue extends at an angle outwardly of the plan of the outer surface of the flange to define an abutment edge.
In accordance with a further broad aspect of the present invention, there is provided a helmet comprising such a bracket secured centrally adjacent a top edge of the frontal portion thereof for releasably securing a wire grid face protector thereto.

of the inverted U-shaped wire. The wires
18
are disposed to define a plurality of apertures dimensioned to prevent passage of hockey sticks and pucks to protect the face of the wearer.
Referring now to
FIGS. 6A-6B
, a loop-shaped wire
46
has a rear hook portion
47
and a front securement portion
48
. The loop-shaped wire
46
is bent over the central top portion
35
of the inverted U-shaped wire
32
and welded under the top portion
22
of the peripheral wire
20
in the rear hook portion
47
defining therein an inwardly angled hook relative to the front securement portion
48
. The front securement portion
48
of the loop-shaped wire
46
is in the plan of the wire grid.
Referring now to
FIGS. 1-3
, two clips
14
are disposed at either side of the wire grid
10
, between the side portion
26
of the peripheral wire
20
and the upright portions
34
of the inverted U-shaped wire
32
. Each clip
14
has a body
50
having an outer wall
52
and an inner wall
54
joined by an upper wall
56
, a lower wall
58
and opposed side edges
60
. Each side wall
60
forms a groove
62
adapted to snap-fit to the upright portion
34
of the inverted U-shaped wire
32
and the side portion
26
of the peripheral wire
20
, respectively. The side edge
60
proximal to a vertical plan perpendicularly crossing the center of the wire grid
10
defines a guide slot
64
adjacent the groove
62
and outwardly disposed with respect thereof. Each guide slot
64
receives a flange
66
disposed at either ends of the shield
12
, to releasably secure same thereto, as explained hereinafter. The outer wall
52
of the body
50
defines an opening
65
for abutting engagement by a resilient outwardly inclined tongue
72
of the flange
66
. The opening
65
is sized to allow the wearer to manually inwardly press the tongue
72
therethrough by the use of a finger.
Referring now to
FIGS. 4A-4B
, it can be seen that the ends of the shield
12
are integrally provided with a flange
66
having an inner surface
68
and an outer surface
70
. The flange
66
is adapted to be received snugly but slidably into the guide slot
64
of the clip
14
. The flange
66
is integrally provided with a tongue
72
having its base connected to the flange
66
near the free end thereof. The tongue
72
is molded in an outward angled projection with respect to the flange
66
. A finger
74
is integrally provided at the top of the tongue
72
and extends inwardly of the inner surface
68
of the flange
66
. The transparent shield
12
is molded from an impact resistant plastic material. The finger
74
is configured to engage in a groove formed in the inner wall defining the guide slot
74
.
FIG. 5
shows, in a cross-section, the flange
66
inserted in the clip
14
, and the tongue
72
engaged in the opening
65
.
As the flange
66
is inserted into the guide slot
64
, the tongue
72
is urged inwardly to a position of alignment with the flange
66
by the inner wall of the guide slot
64
. When the end of the flange
66
touches the bottom of the guide slot
64
, the tongue
72
rises by its resilient action to its normal inclined position which provides an abutment between the outer surface of the tongue
72
and the outer wall
52
of the clip
14
.
In order to release the flanges
66
from the clips
14
, wearer merely presses inwardly on the tongues
72
of the respective flanges
66
through the openings
65
, and then pulls the shield
12
in order to pull the tongues
72
through the guide slots
64
. At this point, there is no further interference by the tongue
72
to retain the flange
66
in place in the clip
14
, and the wearer may simply pull the shield
12
out of engagement.
As seen in
FIGS. 1-3
,
6
A and
6

16
secures the wire grid
10
to the helmet
9
. The bracket
16
has a body
80
with two holes at opposed ends thereof for the insertion of fasteners therethrough, to secure the bracket
16
to the forehead region of the helmet
9
. A U-shaped holder
82
extends outwardly from the face of the body
80
and is elongated in the plan at right angle to the page. The holder
82
is of a maximum height to ensure insertion in the loop formed by the ring-shaped wire
46
, as described hereinbefore. The U-shaped elongated holder
82
forms a groove
84
into which snap-fits the top portion
35
of the inverted U-shaped wire
32
of the wire grid
10
.
As shown in
FIGS. 6A-6B
, the groove
84
has a flared entry portion having a shoulder
86
joining a semi-cylindrical cavity
88
which receives the top portion
35
of the inverted U-shaped wire
32
and allows same to easily rotate therein. The flared entry portion and the shoulder
86
allow the wire
35
to be retained in the cavity
88
.
The bracket
16
has the top portion
35
of the inverted U-shaped wire
32
engaged therein. The wire grid
10
pivots with respect to the bracket
16
from a lowered position, corresponding to hook portion
47
