DETAILED DESCRIPTION
[0038] Representative embodiments according to the inventive subject matter are shown in
[0039] The inventive subject matter is directed to a detachable frontal helmet extension for an item of protective headgear, such as visors or faceguards used on helmets. Examples include visors as used on helmets for off-road sports, such as motocross helmets or downhill bicycling helmets, or faceguards as used on football, hockey, and baseball helmets.
[0040] The visor attaches to a front portion of the helmet, and is generally centered along a midline of the helmet. As used herein, the visor is a distinct structure that couples to the helmet and that extends from the front of the helmet to create a shade or shield to help protect the eyes and face of a wearer from objects and sun or light glare. The detachable visor system includes an attachment system that includes magnetic elements and complementary elements that are magnetically attracted to the magnetic elements, e.g., another magnetic or a ferromagnetic material, such as iron or iron alloys. The strength of the magnetic elements is adapted to balance securely coupling the visor to the helmet during ordinary use of the helmet with the ability to release the visor from the helmet upon impact of the visor with a surface, such as the ground or other hard surface. One or more of the magnetic elements may be disposed along a midline of the helmet or in a generally central area of the visor and helmet. In some embodiments, the attachment system may include a position adjustment mechanism having spaced ridges with integral magnetic elements, allowing for incremental adjustments based on ridge spacing.
[0041]
[0042] Visor 4 has a broad surface that extends laterally across helmet 2. It also extends forward from helmet 2 in a direction that is generally parallel to a horizontal plane, e.g., the ground when in use or top of a user's head. In some embodiments, the visor may pivot around the sides of the helmet at an angle relative to a horizontal plane and the angle may range, for example, anywhere between 90 degrees to +270 degrees relative to a horizontal plane of the helmet. In further embodiments, the visor may be adjustable within a limited range along the upper front side of the helmet, for example, at an angle ranging between 45 and +45 degrees relative to a horizontal plane.
[0043] The attachment system magnetically and detachably connects the visor to the helmet via magnetic elements positioned on the shell and complementary elements located on the visor, or vice versa. The elements may be arranged along various locations on the helmet/visor contact area. In some embodiments, these elements may be arranged in an alternating pattern of permanent magnets and metal inserts on the shell and on the visor, for example as illustrated in
[0044] In other embodiments, the attachment system may include a single strip of magnetic material with complementary interacting elements mounted along the visor/helmet contact area. For example, the visor shown in
[0045] In further embodiments, the visor may be attached to the shell at various locations along the visor/shell contact area and by any number of contact points of magnetic elements.
[0046] In the embodiments shown in
[0047]
[0048] In the embodiment shown, outer shell 26 and inner surface 6 of visor 4 have complementary shapes to keep the visor in place. The attachment system effectively couples visor 4 to helmet 2 based on the complementary contoured shapes of helmet 2 and visor 4 and the magnetic force of magnetic elements 24 and complementary elements 30. In contrast to the existing systems, there is no need for additional coupling features that would require openings in the outer shell of the helmet or that would interfere with aerodynamic features.
[0049]
[0050]
[0051] The attachment system may include any type of magnetic fasteners. The fasteners may include first and second parts containing surfaces of magnetic material. For example, the first part may contain a magnetic material that may be attracted to a permanent magnet in the second part. The magnets and metal inserts may have a button shape, as shown, or an annular shape, or any other shape. The materials used in the attachment system are materials or objects that produce a magnetic field. This magnetic field creates a force that pulls on other ferromagnetic materials like iron and attracts or repels other magnets. The materials may be permanent magnet or materials that can be magnetized, such as ferromagnetic materials. Examples include iron, nickel, cobalt, some alloys of rare earth metals such as neodymium magnets and samarium-cobalt magnets, and some naturally occurring minerals such as lodestone. The elements used in the attachment system are selected based on the overall strength of a magnet. Other examples of magnetic elements that may be used are ceramic magnets and alnico magnets. In some embodiments, injection molded magnets may be used. These magnets are a composite of various types of resin and magnetic powders, allowing parts of complex shapes to be manufactured by injection molding. The physical and magnetic properties of the product depend on the raw materials, but are generally lower in magnetic strength and resemble plastics in their physical properties. In some embodiments, flexible magnets may be used, using a flexible resin or binder such as vinyl, and produced in flat strips, shapes or sheets. These magnets are lower in magnetic strength but can be very flexible, depending on the binder used.
[0052] The complementary elements may include a magnetically attractive material, such as a metal. Suitable materials include iron, nickel, cobalt, steel, stainless steel, or any other suitable metal or metal alloy.
[0053] The magnetic elements and complementary elements are selected to allow the visor to be firmly fixed in place during ordinary use of the helmet. Ordinary use refers to any use of the helmet that is ordinary or common use for the sport or applications in which the helmet is used. For example, a motocross helmet's ordinary use includes use of the helmet associated with driving the motorcycle and withstanding shocks and vibrations. Upon impact with a surface, for example during a crash and contact of the visor with a ground surface or an obstacle, a strong force causes the contact elements to release and allow the visor to break away from the helmet. Impact severity requirements vary widely across helmet types and even across standards prepared for the same helmet type.
[0054] Optionally, the attachment system may include an adjustment mechanism allowing for vertical adjustment of the visor along the helmet, for example to allow a rider to adjust the visor according to the sun conditions. The adjustment mechanism allows for incremental adjustments of the visor relative to the helmet. In some embodiments, the adjustment mechanism may be integrated with magnetic elements of the attachment system.
[0055]
[0056] Another example of an adjustment mechanism is shown in
[0057] In other embodiments, the adjustment mechanism could be a mechanism separate from the magnetic attachment system, for example, conventional mechanical fasteners that hold the visor in position in a releasable engagement that does not interfere with release of the visor upon impact, or a quick release system of plastic interlocking elements. Other embodiments may have an adjustment mechanism that is slideably adjustable. In further embodiments, the adjustment mechanism may comprise a plurality of spaced apart magnetic elements along a vertical line.
[0058] The inventive subject matter allows for a visor to break away of the helmet in a manner that is safer than that of prior art systems because the visor detaches on impact and does not dig into the ground, as prior art visors would. Additionally, the helmet maintains a sleek, aerodynamic finish as the visor attaches without the use of exterior clips or fixtures. It also may allow for adjustability or replacement of the visor.
[0059] The inventive subject matter is further directed to a method for making an attachment system and protective headgear by forming an outer shell and a visor. The inner surface of the visor is shaped to complement a portion of the outer shell which may be a molded material or a composite construction. An attachment system is formed by mounting magnetic elements on the outer shell and complementary elements on the inner surface of the visor at corresponding locations. The magnetic elements are selected based on magnetic properties that are adapted to magnetically attract the complementary elements and that hold the visor in the desired position on the outer shell. The magnetic strength and contoured shapes of visor and helmet hold the visor in place during ordinary use of the headgear, and allow the visor to be released from the headgear upon impact of the visor with a rigid surface.
[0060]
[0061] As shown in
[0062] As shown in
[0063] According to an example embodiment, the first coupling element 124, the second coupling element 134, and/or the third coupling element 144 are configured to couple the visor 100 to the helmet 2 with a breakaway connection. In some embodiments, the first coupling element 124, the second coupling element 134, and/or the third coupling element 144 are or include a magnetically attractive material and the contact point 34, the contact point 36, and/or the contact point 38 include magnets. In some embodiments, the first coupling element 124, the second coupling element 134, and/or the third coupling element 144 are or include magnets and the contact point 34, the contact point 36, and/or the contact point 38 include a magnetically attractive material. In some embodiments, the first coupling element 124, the second coupling element 134, and/or the third coupling element 144 are or include one or more magnets and the contact point 34, the contact point 36, and/or the contact point 38 are or include one or more magnets. In some embodiments, the first coupling element 124, the second coupling element 134, and/or the third coupling element 144 are or include another type of coupling element that releasably couples the visor 100 to the helmet 2 with a breakaway connection (e.g., a snap fit element, a clip, hook and loop fastener, etc.). In some embodiments, the first coupling element 124, the second coupling element 134, and/or the third coupling element 144 are or include another type of coupling that more rigidly secures the visor 100 to the helmet 2 (e.g., screws, rivets, adhesive, etc.).
[0064] In some embodiments, the third coupling element 144 includes an array of coupling elements (e.g., similar to the adjustment mechanism 40, the adjustment mechanism 60, etc.). The array of coupling elements may facilitate toolless pivotal adjustment of an angle at which the visor 100 extends from the helmet 2. In such embodiments, the visor 100 may thereby be capable of selectively pivoting about an axis, shown as pivot axis 190, that extends between the first coupling element 124 and the second coupling element 134. In some embodiments, the contact point 36 includes an array of coupling elements that may facilitate toolless pivotal adjustment of an angle at which the visor 100 extends from the helmet 2.
[0065] The central support 140 can include a first extension, shown as first flange 146, extending from a first side (e.g., a left side, etc.) of the central interface 142, rearward of the trailing edge 114 of the bill 110, and a second extension, shown as second flange 148, extending from an opposing second side (e.g., a right side, etc.) of the central interface 142, rearward of the trailing edge 114 of the bill 110. The first flange 146 can define a first surface, shown as first interfacing surface 150, and the second flange 148 can define a second surface, shown as second interfacing surface 152. According to an example embodiment, the first interfacing surface 150 and the second interfacing surface 152 are configured (e.g., shaped, positioned, etc.) to at least partially engage the central location 14 at the front 16 of the helmet 2 when the visor 100 is coupled to the helmet 2.
[0066] As shown in at least
[0067] The first fin 160 can define a first surface, shown as third interfacing surface 162, and the second fin 170 can define as second surface, shown as fourth interfacing surface 172. As shown in
[0068] In some embodiments, the first platform 80 and/or the second platform 82 are structured as protrusions having a surface (e.g., a flat surface, a curved surface, etc.) that extends from the shell 26. The surface of each of the protrusions may be shaped to correspond with the third interfacing surface 162 of the first fin 160 and/or the fourth interfacing surface 172 of the second fin 170. In some embodiments, the first platform 80 and/or the second platform 82 are structured as recesses defined by the shell 26. The recesses may be shaped (e.g., have a flat surface, a curved surface, etc.) to correspond with the third interfacing surface 162 of the first fin 160 and/or the fourth interfacing surface 172 of the second fin 170.
[0069] In some embodiments, (i) the third interfacing surface 162 includes a fourth coupling element and the fourth interfacing surface 172 includes a fifth coupling element and (ii) the first platform 80 and the second platform 82 include corresponding coupling elements. In such embodiments, the visor 100 may not include the third coupling element 144 and/or the central support 140. In some embodiments, the visor 100 includes two central supports 140, one positioned on each side of the midline 180.
[0070] In some embodiments, the helmet extension is additionally or alternatively configured as a rear helmet extension. By way of example, the rear helmet extension may be or include a detachable vent, a detachable rear fin, and/or still another type of detachable helmet accessory configured to couple to the sides and/or rear of the helmet 2. The rear helmet extension may be configured to increase or improve the aerodynamics of the helmet 2. For example, the helmet 2 may include coupling elements (e.g., metal inserts, magnets, clips, similar to the contact points 34, 36, and 38, etc.) variously positioned about the rear and/or sides of the shell 26 of the helmet 2. The rear helmet extension may include corresponding coupling elements (e.g., magnets, metal inserts, clips, similar to the coupling elements 124, 134, 144, etc.) that interface with the coupling elements on the rear and/or sides of the helmet 2 to facilitate coupling the rear helmet extension thereto with a breakaway connection. The rear helmet extension may thereby releasably couple to the helmet 2 such that under sufficient loading, the rear helmet extension detaches from the helmet 2 (e.g., to prevent torsion of the wearer's head and/or neck during an impact with the ground, etc.).
