Abstract

An adapter for mounting a face shield on a hard hat self-centers and aligns itself with respect to the hard hat brim. An arcuate main body has an arcuate guard portion that extends over the hard hat brim. A central retention tab engages the front edge of the hard hat brim. Opposing guide channels engage the side edges of the hard hat brim and limit rotation of the main body with respect to the hard hat. Cantilever springs within the guide channels engage the side edges of the hard hat brim to self-center the brim with respect to the main body. A retention member extending around the back of the hard hat secures the main body to the hard hat. A face shield mounting bracket is pivotally mounted to the main body portion and supports a face shield. A clutching mechanism helps control the orientation of the face shield.

Description

BACKGROUND
• The present disclosure relates to a hard hat adapter that allows a user to releasably mount a face shield on a hard hat.
• Current head gear products are generally hard hat specific, meaning they do not universally fit a variety of different size and shape hard hats. Often, a user must acquire a specific hard hat adapter that is configured for mounting a face shield on a specific hard hat.
SUMMARY OF THE DISCLOSURE
• The present disclosure relates to an improved adapter for mounting a face shield to a hard hat where the adapter universally fits to most hard hats. The adapter includes a pivot that allows the user to pivot the face shield to a lowered position in front of the user's face and to pivot the face shield to a raised position away from the user's face. The hard hat adapter is self-centering and self-aligning with respect to the hard hat.
• A universal hard hat adapter is provided for mounting a face shield on plurality of commonly used hard hats. The present hard hat adapter includes a main body that is configured for mounting on a hard hat. The main body is substantially arcuate to generally follow the curvature of commonly used hard hat brims, and has a first end and a second end. The hard hat adapter further includes an arcuate guard portion that extends inwardly from the main body and is configured to extend over the brim of the hard hat when the hard hat adapter is mounted on the hard hat. In this regard, the arcuate guard portion overlaps with the brim so that the arcuate guard portion and the brim cooperate to substantially prevent debris from falling between the main body and the brim of the hard hat on which the adapter is mounted.
• To secure the hard hat adapter to a hard hat and to help align the hard hat adapter on the hard hat, a central retention tab extends from a lower surface of the main body. The central retention tab is configured and arranged to engage a forward edge of the brim of the hard hat. The adapter further includes opposing inwardly facing guide channels that extend inwardly from a lower surface of the main body. The guide channels receive the hard hat brim between upper and lower guide channel surfaces, and further limit rotation of the main body with respect to the hard hat when the hard hat adapter is mounted on a hard hat.
• To center the hard hat adapter on the hard hat, the adapter includes opposing cantilever springs secured within the opposing guide channels of the hard hat adapter. Each cantilever spring has a free moving end that engages a side edge of the brim of the hard hat and centers the brim relative to the adapter.
• To further secure the hard hat adapter to the hard hat, a retention member is provided. In the exemplary embodiment, the retention member is preferably a spring, such as a coil spring, that has a first end secured to a first end of the main body and a second end secured to a second end of the main body. The coil spring can be extended around the rear of the hard hat, to maintain sufficiently firm engagement of the hard hat adapter with the hard hat. Other retention members are possible. For example, the retention member could be other types of springs, an elastic band, or a clip.
• The hard hat adapter further includes a pivoting face shield mounting bracket that supports a face shield in front of a user's face when a user is wearing the hard hat and adapter. The face shield is removably mounted on the mounting bracket to permit replacement of the face shield when needed. The face shield mounting bracket is rotatably coupled to the main body, and is pivotable with respect to the main body. More specifically, the face shield mounting bracket can be pivoted between a lowered orientation (“down” position) where the face shield is positioned in front of the user's face, and a raised orientation (“up” position) where the face shield is positioned up and away from the user's face.
• The hard hat adapter still further includes a clutching mechanism that rotatably or pivotably couples the mounting bracket to the main body. The clutching mechanism includes a plurality of angularly spaced interlocking detents that enables the mounting bracket to be conditionally stable in various orientations with respect to the main body. This allows the mounting bracket to be releasably fixed in the lowered orientation or the raised orientation, as well as a plurality of additional angular positions, until the user causes the mounting bracket to move. The clutching mechanism may be made of metal or another material.
• The face shield mounting bracket and the main body are configured so that there is no gap between the face shield mounting bracket and the main body when the face shield mounting bracket is in the lowered orientation and the hard hat adapter is viewed from above. This substantially prevents debris from falling between the face shield mounting bracket and the main body of the hard hat adapter. The face shield mounting bracket preferably has an upper mounting bracket portion that extends over a part of the main body when the mounting bracket is in the lowered position. This helps to ensure that there is no gap between the upper mounting bracket and the main body.
• The hard hat adapter can be provided to a user with a face shield mounted on the hard hat adapter. Alternatively, the hard hat adapter can be provided to a user without a face shield, allowing a user to attach a face shield to the hard hat adapter according to the user's preferences.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENT
• Referring now to the drawings, an exemplary embodiment of the hard hat adapter of the present disclosure is illustrated and generally indicated at10 inFIGS. 1-8. As will hereinafter be more fully described, the instanthard hat adapter10 allows a user to selectively mount aface shield12 to ahard hat14 which may have a range of dimensions.
• Thehard hat adapter10 of the present disclosure has an arcuatemain body16 that is secured to thehard hat14 and has a faceshield mounting bracket18 rotatably coupled to themain body16 for supporting theface shield12. Acentral mounting tab20 and opposingguide channels22A,22B on themain body16 of thehard hat adapter10 facilitate alignment of thehard hat adapter10 with thehard hat14, so that theface shield12 secured to thehard hat adapter10 is positioned substantially in front of a user's face when the user wears thehard hat14. Cantileversprings24A,24B on thehard hat adapter10 engage thebrim26 of thehard hat14 and facilitate alignment and centering of thehard hat adapter10 with respect to thehard hat14.
• Themain body16 of thehard hat adapter10 is substantially arcuate having a first end that is configured to extend to one side of thehard hat14, and a second end that is configured to extend to a second side of thehard hat14. This is best seen inFIGS. 2 and 3, where theadapter10 has been mounted on thehard hat14.
• To substantially or entirely prevent debris from falling between themain body16 and thebrim26 of thehard hat14, anarcuate guard portion28 formed on themain body16 extends inwardly from themain body16.FIGS. 2 and 3 show how thearcuate guard portion28 extends sufficiently horizontally inwardly so that thehard hat brim26 is underneath thearcuate guard portion28 from a point on the left side of thehard hat14, around the front of thehard hat14, and to a point on the right side of thehard hat14. Thearcuate guard portion28 does not need to follow a specific contour of a forward edge of abrim26 of ahard hat14 because thearcuate guard portion28 is configured to extend over the forward edge of thebrim26 of thehard hat14.
• Referring toFIGS. 3 and 4, the forward edge of thebrim26 of thehard hat14 is received in thecentral mounting tab20 that extends from a lower surface of theguard portion28. Thecentral mounting tab20 is configured and arranged to engage a forward edge of thebrim26 of a typical hard hat so that thecentral mounting tab20 limits movement of themain body16 with respect to thehard hat14. Thecentral mounting tab20 has a horizontally extending portion that has an upper surface that is below thehard hat brim26. Thearcuate guard portion28 of themain body16 has a lower surface that is above thehard hat brim26. Together these surfaces limit the movement of thehard hat14 with respect to themain body16 of thehard hat adapter10.
• Referring now toFIGS. 4-7B, the adapter further includes inwardly facing opposingguide channels22A,22B which extend inwardly from a lower surface of themain body16. Eachguide channel22A,22B receives a side edge portion of the hard hat brim26 to limit rotation of thehard hat adapter10 with respect to thehard hat14.
• To center thehard hat adapter10 on thehard hat14, theadapter10 includes opposing cantilever springs24A,24B secured within theguide channels22A,22B and extending inwardly from themain body16 so that, when the user mounts thehard hat adapter10 to ahard hat14, thehard hat adapter10 automatically centers itself with respect to thehard hat14. Eachcantilever spring24A,24B has an anchor end that is secured to a wall of therespective guide channel22A,22B and a free moving end extending inwardly from the guide channel that engages the side edge of the hard hat brim. The free moving end of eachcantilever spring24A,24B frictionally engages and centers thebrim26 of thehard hat14 with respect to themain body16. The deflection of the cantilever springs24A,24B is determined by the outer width of thehard hat brim26. Narrowerhard hats14 will cause the cantilever springs24A,24B to deflect less, and widerhard hats14 will cause the cantilever springs24A,24B to deflect more. The left and right cantilever springs24a,24B are configured to have substantially identical force-deflection characteristics. When thehard hat adapter10 is mounted on ahard hat14, the forces on the left and right cantilever springs24A,24B will substantially balance, so that the left andright springs24A,24B are deflected substantially the same amount, and thehard hat14 is therefore substantially centered with respect to thehard hat adapter10.
• To mount thehard hat adapter10 on thehard hat14, a user simply slides thehard hat14 into thecentral mounting tab20 of themain body16, so the forward edge of thehard hat brim26 is entirely under thearcuate guard portion28 and captured in theretention tab20, and then secures aretention member30 around the rear of thehard hat14. Theretention member30 of the exemplary embodiment is illustrated as a coil spring having first and second ends, which are respectively secured to first and second ends of themain body16. Theretention member30 extends around the rear of thehard hat14 to maintain thebrim26 of thehard hat14 in secure engagement with thecentral mounting tab20. While acoil spring30 is illustrated, other types of retention members, such as other springs, elastic bands or clips, are contemplated without departing from the scope of the present disclosure.
• As best illustrated inFIGS. 7A and 7B, the hard hat adapter has a faceshield mounting bracket18 that is capable of supporting aface shield12 in front of thehard hat14 to protect the face of a user wearing thehard hat14. The faceshield mounting bracket18 is arcuate in shape and is pivotably coupled to the main body by aclutch mechanism32. The rotatableclutch mechanism32 allows the faceshield mounting bracket18 to be pivoted back and forth between a lowered orientation (FIGS. 1-3,7A) and a raised orientation (FIG. 7B). The faceshield mounting bracket18 and themain body16 are configured and arranged so there is no gap between the faceshield mounting bracket18 and themain body16. In this regard, thebracket18 includes an inwardly extendingflange portion34 which extends over theguard portion28. This is evident when thehard hat adapter10 is viewed from above (FIG. 2) and the faceshield mounting bracket18 is in the lowered orientation (FIGS. 1-5 and7A). Theflange34 overlaps theguard portion28 and substantially prevents debris from falling between the faceshield mounting bracket18 and themain body16.FIGS. 5 and 7A best show how there is no gap between themain body16 and the mountingbracket18 when the mountingbracket18 is in the lowered orientation and viewed from above or below.
• The faceshield mounting bracket18 is pivotably coupled to the main body by a clutchingmechanism32 having a plurality of angularly spaced interlocking detents36 (seeFIG. 8). The clutchingmechanism32 thus allows the mounting bracket to be fixed in more than one position relative to themain body16. This allows a user to rotate the mountingbracket18 up or down to a desired orientation with respect to themain body16, and leave it in that orientation.FIGS. 7A and 7B show thebracket18 in a lowered orientation and a raised orientation, respectively. When the user desires to move the mountingbracket18 to a specific orientation, the user simply applies a force to the mountingbracket18 to overcome the frictional force of the clutchingmechanism32. The clutchingmechanism32 is preferably made of metal, but other materials are within the scope of the present disclosure.
• Theface shield12 is removably mounted on the hard hat adapter by conventional knowninterfitting mounting components38 so that theface shield12 is interchangeable and replaceable by the user.
• While there is shown and described herein certain specific structure embodying the hard hat adapter, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claims.
