The wire grid face protector is detachable from the helmet by upwardly pivoting same with respect to the helmet, and by pulling the wire member out of the groove. The transparent shield and the wire grid are quickly removable and securely in place when in a position of use.
Description
HELMET FACE PROTECTOR ATTACHMENT SYSTEM
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 gri.d 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. Patent No. 4,031,564 issued to Wood on June 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.

(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. Patent No. 4,031,564 issued to Wood on June 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.
- 2 -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. Patent 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. Patent No. 4,856,100 issued to Desy et al. on August 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 therefore provides a clip for releasably securing a transparent shield to a wire grid face protector of a helmet, the clip comprising 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 having a guide slot adapted to receive therein an attachment flange of a transparent shield, and an opening in an outer wall of the retaining body configured to receive in abutting engagement a resilient, outwardly inclined tongue of the attachment flange, the transparent shield being disconnectable from the clip by inwardly depressing the tongue in the opening and pulling the tongue from the guide slot.

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
7 -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
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
- 8 -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, the 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, 6A and 6B, a bracket 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.
