Definitions
- the present invention relates to a protective helmet, such as a hard hat or fire helmet, with a system allowing for attachment of interchangeable accessories, such as a faceshield or goggles, to the helmet.
- a protective helmet such as a fire helmet or a hard hat, commonly includes a shell and a suspension contained within the shell.
- the shell and suspension cooperate to provide the requisite level of protection.
- the shell of the protective helmet causes any force of impact to be spread across the surface area of the shell.
- the suspension of the protective helmet separates the wearer's head from the shell such that there is an air gap between the shell and the wearer's head that provides for further attenuation of the force of an impact to the shell.
- the shell When an object strikes the shell of the helmet, the shell itself flexes inward and the straps of the suspension will stretch.
- the air gap accommodates the flexing of the shell and stretching of the straps, but, under normal conditions, prevents the wearer's head from contacting the shell of the protective helmet.
- various accessories may be secured to the protective helmet, for example, a faceshield, goggles, or a visor. Such accessories are typically secured to the outer surface of the protective helmet. Most existing systems do not allow for rapid attachment and detachment of such an accessory from the protective helmet. Furthermore, existing systems do not allow various accessories to be attached at a common location on the outer surface of the helmet.
- the present invention is a protective helmet with a system allowing for attachment of interchangeable accessories, such as a faceshield or goggles.
- This system includes interfaces secured to the helmet and capable of receiving various brackets, each bracket being used to secure a different accessory to the protective helmet.
- an interface is secured on either side of the helmet on an inside surface of the helmet.
- Each such interface has a structure that defines a slot for receiving a bracket associated with an accessory that is attached to the helmet.
- each accessory is provided with appropriate brackets for the attachment of that accessory, for example, the faceshield is attached to the helmet with a pair of faceshield brackets and the goggles are attached to the helmet with a distinct pair of goggle brackets.
- each bracket has a mating end that has three prongs, including a center prong which is capable of limited flexing relative to two side prongs.
- Each bracket additionally has a pivot point end that is secured to the accessory.
- the mating end of each bracket associated with the accessory is inserted into a corresponding slot defined by one of the interfaces.
- the bottom edge of the helmet interface contacts a wedge-shaped tab extending from the center prong of the mating end, causing a depression or flexing of the center prong relative to the side prongs.
- the center prong can return from its depressed state, locking the bracket into the interface and securing the accessory to the protective helmet.
- a wearer simply depresses the tab associated with each bracket and withdraws the mating end of each bracket from the slot defined by the respective interface.
- a faceshield is typically designed to pivot about an axis which is located approximately midway between the front and rear of the helmet resulting in an arc of movement of the faceshield that is generally concentric with the wearer's head.
- the location approximately midway between the front and rear of the helmet is too far forward for the attachment of goggles.
- the length of the brackets can be altered for each accessory, ensuring a proper pivot axis for that accessory.
- each faceshield bracket is designed such that the pivotal axis defined by the brackets of the faceshield is approximately midway between the front and rear of the helmet, while the pivot point end of each goggle bracket is more elongated to provide a more rearward pivotal axis for the goggle straps.

Abstract
A protective helmet with a system allowing for attachment of interchangeable accessories includes interfaces secured to the helmet and capable of receiving various pairs of brackets, each pair of brackets being used to secure a different accessory to the protective helmet. Although the interfaces are located at predetermined locations, the brackets are of varying lengths to ensure a proper pivot axis for the chosen accessory.
Description
- This application claims priority to U.S. Provisional Application Serial No. 60/455,792 filed Mar. 19, 2003, the entire disclosure of which is incorporated herein by this reference.
- The present invention relates to a protective helmet, such as a hard hat or fire helmet, with a system allowing for attachment of interchangeable accessories, such as a faceshield or goggles, to the helmet.
- A protective helmet, such as a fire helmet or a hard hat, commonly includes a shell and a suspension contained within the shell. The shell and suspension cooperate to provide the requisite level of protection. Specifically, the shell of the protective helmet causes any force of impact to be spread across the surface area of the shell. The suspension of the protective helmet separates the wearer's head from the shell such that there is an air gap between the shell and the wearer's head that provides for further attenuation of the force of an impact to the shell. When an object strikes the shell of the helmet, the shell itself flexes inward and the straps of the suspension will stretch. The air gap accommodates the flexing of the shell and stretching of the straps, but, under normal conditions, prevents the wearer's head from contacting the shell of the protective helmet.
- Although such “strap” suspension systems are commonly employed in protective helmets, other force attenuation means may also be used. For example, foam or similar padding may be secured to the internal surface of the shell of the protective helmet. The use of such padding is common in the construction of sports-related helmets, such as baseball helmets, football helmets, and bicycle helmets.
- Depending on the application for which the protective helmet is worn, various accessories may be secured to the protective helmet, for example, a faceshield, goggles, or a visor. Such accessories are typically secured to the outer surface of the protective helmet. Most existing systems do not allow for rapid attachment and detachment of such an accessory from the protective helmet. Furthermore, existing systems do not allow various accessories to be attached at a common location on the outer surface of the helmet.
- Accordingly, there remains a need in the art for a protective helmet incorporating a system which satisfactorily addresses the need for rapid attachment and detachment of accessories to and from the helmet. Additionally, there remains a need in the art for a protective helmet incorporating a system which simplifies attachment of such accessories by allowing attachment at a common location on the outer surface of the helmet.
- The present invention is a protective helmet with a system allowing for attachment of interchangeable accessories, such as a faceshield or goggles. This system includes interfaces secured to the helmet and capable of receiving various brackets, each bracket being used to secure a different accessory to the protective helmet.
- In one exemplary embodiment, an interface is secured on either side of the helmet on an inside surface of the helmet. Each such interface has a structure that defines a slot for receiving a bracket associated with an accessory that is attached to the helmet. Accordingly, each accessory is provided with appropriate brackets for the attachment of that accessory, for example, the faceshield is attached to the helmet with a pair of faceshield brackets and the goggles are attached to the helmet with a distinct pair of goggle brackets.
- Regardless of the accessory, each bracket has a mating end that has three prongs, including a center prong which is capable of limited flexing relative to two side prongs. Each bracket additionally has a pivot point end that is secured to the accessory. To secure an accessory to the protective helmet, the mating end of each bracket associated with the accessory is inserted into a corresponding slot defined by one of the interfaces. As the mating end of each bracket is inserted into the slot, the bottom edge of the helmet interface contacts a wedge-shaped tab extending from the center prong of the mating end, causing a depression or flexing of the center prong relative to the side prongs. However, once the tab is through the slot, the center prong can return from its depressed state, locking the bracket into the interface and securing the accessory to the protective helmet. To detach the accessory, a wearer simply depresses the tab associated with each bracket and withdraws the mating end of each bracket from the slot defined by the respective interface.
- It is important to recognize that the ideal attachment location for various accessories sometimes differs. For example, a faceshield is typically designed to pivot about an axis which is located approximately midway between the front and rear of the helmet resulting in an arc of movement of the faceshield that is generally concentric with the wearer's head. However, the location approximately midway between the front and rear of the helmet is too far forward for the attachment of goggles. Accordingly, in the present invention, although the position of the interfaces is fixed relative to the helmet, the length of the brackets can be altered for each accessory, ensuring a proper pivot axis for that accessory. For example, the pivot point end of each faceshield bracket is designed such that the pivotal axis defined by the brackets of the faceshield is approximately midway between the front and rear of the helmet, while the pivot point end of each goggle bracket is more elongated to provide a more rearward pivotal axis for the goggle straps.

- FIG. 8 is a bottom view of a portion of the helmet of FIG. 5, illustrating the attachment of one bracket of the goggles to the protective helmet.
- The present invention is a protective helmet with a system allowing for attachment of interchangeable accessories, such as a faceshield or goggles. This system includes interfaces secured to the helmet and capable of receiving various brackets, each bracket being used to secure a different accessory to the protective helmet.
- Referring first to FIGS. 1 and 5, an exemplary embodiment of the
protective helmet 10 is illustrated, in this case, a fire helmet. FIG. 1 illustrates thehelmet 10 with afaceshield 12 attached thereto using a pair offaceshield brackets faceshield bracket 14′ is shown in FIG. 2), and FIG. 5 illustrates thehelmet 10 withgoggles 16 attached thereto using a pair of goggle brackets 18 (although only one goggle bracket is shown). - Referring now to FIGS. 3 and 8, an
interface 20 is secured to aninside surface 22 of theprotective helmet 10. Although only one side of thehelmet 10 is shown in FIGS. 3 and 8, there is a second interface that is the mirror-image of thefirst interface 20 on the opposite inside surface of thehelmet 10. In this exemplary embodiment, eachinterface 20 includes acrossbar 24 with two substantiallyparallel legs respective legs helmet 10, thereby defining aslot 30 that is interposed between theinner surface 22 of thehelmet 10 and thecrossbar 24 of theinterface 20. In this exemplary embodiment, thelegs crossbar 24 actually extend from and are integral with aninner ring 23 that supports thesuspension 13 of theprotective helmet 10. - Also, although not essential to the present invention, in this exemplary embodiment and as illustrated in FIGS. 3 and 8, there is an additional
structural member 25 that is secured to the upper surface of thecrossbar 24 which is used as an attachment point for a portion of a chinstrap 60 (as illustrated in FIG. 3). Bolts orsimilar fasteners structural member 25, thelegs protective helmet 10 to secure these components relative to one another. - Turning now to the
brackets 14 for attaching thefaceshield 12 to theprotective helmet 10, and with reference to FIG. 4 (in which one bracket is illustrated), thebracket 14 is generally L-shaped and has amating end 32 adapted to be received in theslot 30 defined by one of thehelmet interfaces 20. Themating end 32 of thebracket 14 includes threeprongs center prong 36 being capable of limited flexing or movement relative to the side prongs 38, 40. Additionally, thecenter prong 36 of thebracket 14 has anintegral tab 48, which has a wedge shape, the importance of which will be discussed below. - Referring now to FIGS. 2 and 4, the
faceshield 12 includes twolateral appendages protective helmet 10. Thefaceshield brackets pivot point ends respective appendages pivot point end faceshield 12 and eachbracket - As best illustrated in FIG. 3, to secure the
faceshield 12 to theprotective helmet 10 requires only the insertion of themating end 32 of eachbracket 14 into theslot 30 defined by one of thehelmet interfaces 20. As themating end 32 of eachbracket 14 is inserted into theslot 30, the bottom edge of thehelmet interface 20 contacts the wedge-shapedtab 48 extending from thecenter prong 36 of themating end 32, causing a depression or flexing of thecenter prong 36 relative to the side prongs 38, 40. However, once thetab 48 clears thecrossbar 24 of thehelmet interface 20, thecenter prong 36 can return from its depressed state on the other side of thehelmet interface 20. This action locks thebracket 14 into theinterface 20, thereby securing thefaceshield 12 to theprotective helmet 10 with the back of thetab 48 of thecenter prong 36 resting against the edge of thecrossbar 24 of thehelmet interface 20. - Referring now to FIG. 7, the
brackets 18 for attaching thegoggles 16 to theprotective helmet 10 are also generally L-shaped and have amating end 34 adapted to be received in theslot 30 defined by one of the helmet interfaces 20. Themating end 34 of thebracket 18 includes threeprongs center prong 42 being capable of limited flexing or movement relative to the side prongs 44, 46. Additionally, thecenter prong 42 of thebracket 18 has anintegral tab 50, which has a wedge shape, the importance of which will be discussed below. - As illustrated in FIGS. 5 and 6, the
goggles 16 include twostraps 58, one extending from either side of the goggles 16 (although only one strap is illustrated in the Figures). Each of thegoggle brackets 18 include apivot point end 62 which is secured to one of thestraps 58 by a bolt, rivet or similar fastener. - As best illustrated in FIG. 8, to secure the
goggles 16 to theprotective helmet 10, themating end 34 of eachbracket 18 is inserted into theslot 30 defined by one of the helmet interfaces 20. As themating end 34 of thebracket 18 is inserted into theslot 30, the wedge-shapedtab 50 of thecenter prong 42 is depressed relative to the side prongs 44, 46. Once thetab 50 clears thecrossbar 24 of thehelmet interface 20, thecenter prong 42 returns from its depressed state on the other side of thehelmet interface 20, thereby securing thebracket 18, and thus thegoggles 16, to theprotective helmet 10. - To detach the
faceshield 12 orgoggles 16, a wearer simply depresses the tabs of the associated brackets, and then withdraws the bracket from theslots 30 defined by theinterfaces 20. Such detachment can be easily accomplished even while theprotective helmet 10 is being worn. - It is important to recognize that the ideal attachment location on the
protective helmet 10 for various accessories sometimes differs. For example, one of the challenges in creating a protective helmet with a system allowing for attachment of interchangeable accessories is that the ideal attachment location is different depending on the chosen accessory. For example, afaceshield 12 is typically designed to pivot about an axis which is located approximately midway between the front and rear of thehelmet 10 resulting in an arc of movement of thefaceshield 12 that is generally concentric with the wearer's head. However, the location approximately midway between the front and rear of thehelmet 10 is too far forward for the attachment ofgoggles 16. In this regard, if the distal ends of the goggle straps 58 were attached at this midpoint location on thehelmet 10, there would not be a sufficient distance between the attachment points and thegoggles 16 to allow adjustment of the length of thestraps 58 on each side to permit a comfortable and effective fit for a range of head sizes, or to permit sufficient elongation of thestraps 58 for storage of thegoggles 16 on the front of thehelmet 10 when not in use. Furthermore, when the exemplary system of the present invention is used with aprotective helmet 10 having a brim that is somewhat wider than thegoggles 16, there is a tendency for thestraps 58 to be pulled slightly outward from thegoggles 16 to the attachment point on thehelmet 10. If the attachment point on thehelmet 10 is too close to thegoggles 16, it can cause thegoggles 16 to be stretched outward as thestraps 58 are tightened, preventing thegoggles 16 from sealing securely against the wearer's face, particularly at the ends. However, if the attachment point on thehelmet 10 is distanced to the rear, thestraps 58 can be tightened to allow thegoggles 16 to securely seal against the wearer's face. - The helmet interfaces20 of the exemplary embodiment of the present invention are located approximately midway between the front and rear of the
helmet 10. In this regard, theinterfaces 20 are located at the ideal points for pivotal attachment of the twolateral appendages faceshield 12, approximately midway between the front and rear of thehelmet 10. However, theinterfaces 20 are not located at the ideal points for pivotal attachment of the goggle straps 58. Accordingly, as best illustrated in FIGS. 5 and 6, thepivot point end 62 of eachgoggle bracket 18 is elongated to provide a more rearward pivotal attachment location for eachgoggle strap 58 on thehelmet 10. In this exemplary embodiment, thebrackets 18 move the pivot axis for thegoggles 18 approximately 2.25 inches behind theinterfaces 20. - In summary, both the
faceshield bracket 14 and thegoggle bracket 18 are designed to mate with thehelmet interface 20; however, by using differing lengths of thebrackets protective helmet 10. - Lastly, although a
faceshield 12 andgoggles 16 are shown in the Figures and referred to in this description, the present invention contemplates that the system of the present invention could be used to secure various accessories theprotective helmet 10, with the length of the bracket associated with each such accessory ensuring a proper pivot axis for that accessory. For example, the ideal attachment location for a visor may be a more frontward attachment location on the protective helmet. - It will be obvious to those skilled in the art that further modifications may be made to the embodiments described herein without departing from the spirit and scope of the present invention.
