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.

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
