1. Field of the Invention
The invention relates to protective headgear, and particularly helmets. More specifically, the invention is directed to a chin strap retainers for fitting and positioning protective headgear on a wearer's head.
2. Description of the Prior Art
There are many types of protective headgear which are presently in use for a variety of recreational activities and work-related uses. In order to be effective, headgear must be properly secured to the wearer's head, and a chin strap system is commonly used to provide the required securement. For equestrian and bicycle headgear applications, each side of the headgear usually has two depending chin strap elements, one in front of the wearer's ear and the other behind the ear. Situated below the wearer's ear is a slideable chin strap retainer that gathers the front and rear chin strap elements into a substantially overlapping arrangement that has the appearance of a single strap link (albeit with the thickness of the two overlapping straps). This produces a “Y” shape with the upper legs of the “Y” extending upwardly to the headgear and the lower leg of the “Y” extending downwardly to define the single strap link. The strap links on each side of the headgear extend to corresponding buckle elements that are releasably connectable to each other under the wearer's chin.
The above-mentioned chin strap retainer is sometimes also referred to as a slider, a strap adjustment or a strap divider. Its function is to raise and lower the point at which the strap elements forming the upper legs of the “Y” join together below the ear. This adjustment is important to achieving a comfortable and correct headgear fit. For example, the strap retainer should be low enough to avoid interference with the wearer's ears, but not so low as allow the headgear to shift from side to side. The chin strap retainer also allows the length of the forward and rearward straps to be adjusted independently in order to change the position (angle) of the headgear on the wearer's head.
Although prior art chin strap retainers generally function effectively once they are correctly adjusted, these retainers are often difficult to adjust, are sometimes prone to breakage, and may detract from the decorative features of the headgear. Moreover, it is critical that the chin strap retainers be capable of locking onto the strap elements and that they resist sliding when large downward pull forces are applied to the strap elements. Such forces may be experienced during a crash event. The chin strap retainers must substantially maintain their locked position under such circumstances so that the headgear remains snugly fitted on the wearer's head and does not tilt or roll to a position wherein the wearer's head is partially unprotected. Accordingly, it would be desirable to provide an improved chin strap retainer design.
SUMMARY OF THE INVENTIONIn accordance with the present invention, a chin strap retainer is provided for use with headgear having a pair of chin straps depending from each side thereof. A substantially circular frame of the chin strap retainer defines all open interior region. A primary cross member extends across a central portion of the open interior region and a pair of secondary cross members are disposed on either side of the primary cross member. The frame and the cross members are part of a single integral workpiece. A pair of strap openings are provided between the primary cross member and the secondary cross members. A pair of apertures are provided between said secondary cross members and the flame.
According to exemplary disclosed embodiments, the frame may be formed as a ring member of substantially uniform cross-sectional shape. The open interior region may be substantially circular in shape. The frame may be substantially planar in side view orientation. It may be continuous or noncontinuous. When the frame is formed as a ring member, the secondary cross members may be formed as mutually parallel cylindrical posts having substantially the same cross-sectional size and shape. Alternatively, one or more of the frame, the first secondary cross member or the second secondary cross member may comprise an irregular or non-uniform cross-sectional shape. The chin strap retainer can be made entirely from metal for strength and durability. A cap call be removably attached to the frame. The cap may comprise clips that clip to the frame at the first and second apertures or at other suitable locations.
A headgear may also be provided that includes a forward portion, a rearward portion, two lateral portions, a continuous lower rim and an upper crown, pair of forward and rearward chin straps depending from each of said lateral portions, and a pair of chin strap retainers each slidably retaining one of said chin strap pairs. The chin strap retainers may be constructed in the manner summarized above in the preceding two paragraphs.
A combination chin strap retainer and decorative cap may be further provided. The chin strap retainer may include a substantially circular, substantially planar frame having an open interior region, a primary cross member integral with the frame and extending across a central portion of the open interior region, a first strap opening on a first side of the primary cross member, and a second strap opening on a second side of the primary cross member. The decorative cap may be provided by a substantially circular cap removably or permanently attached to the frame. A removable attachment may be provided by way of clips, at least one of which is flexible.
The foregoing and other features and advantages of the present invention will be apparent from the following more particular description of a preferred embodiment of the invention, as illustrated in the accompanying Drawings, in which:
Turning now to the Drawing, wherein like reference numbers designate like elements in all of the several views,
The headgear 4 includes a strap retention system 20 for attaching the headgear to a wearer's head. The strap retention system 20 includes, on each side of the headgear 4, a forward strap element 22 and a rearward strap element 24 that are mounted to the headgear in conventional fashion. One of the chin strap retainers 2 is used to join the forward and rearward strap elements 22 and 24 on each side of the headgear 4 into a substantially overlapping arrangement that has the appearance of a single strap link 26 (albeit with the thickness of the two overlapping straps). This produces the “Y” shape referred to by way of Background above, with the upper legs of the “Y” (the strap elements 22 and 24) extending upwardly to the headgear 4 and the lower leg of the “Y” extending downwardly to define the single strap link 26. Each strap link 26 connects to a respective buckle element 28 of conventional design that is releasably connectable to its counterpart buckle element under the wearer's chin. As further described by way of background above, the position of the chin strap retainers 2 can be adjusted upwardly and downwardly to raise and lower the point at which the strap elements 22 and 24 join together below the wearer's ear. The chin strap retainer 2 also allows the length of the forward and rearward strap elements 22 and 24 to be adjusted independently in order to change the position (angle) of the headgear 4 on the wearer's head.

The cross member 32 is a primary cross member that preferably extends through the center of the interior region 38. If the frame 30 is a circular ring member, the primary cross member 32 will extend along a diameter the ring member, which will normally be the widest portion of the ring member and of the interior region 38. The primary cross member 32 intersects the frame 30 at two locations 32A and 32B. The cross members 34 and 36 are secondary cross members that are preferably disposed equidistantly from the central cross member 32. If the frame 30 is a circular ring member, the secondary cross members 34 and 36 will extend along equal length chords of the ring member, with the chord length being less than the length of the primary cross member 32. The secondary cross member 34 intersects the frame 30 at two locations 34A and 34B. Similarly, the secondary cross member 36 intersects the frame 30 at two locations 36A and 36B.

The chin strap retainer 2 is fabricated from metal instead of plastic, and thus can be made sufficiently strong to resist breakage or excessive flexing while utilizing structural members that are non-bulky and relatively thin. By controlling the dimensions of these structural members, the chin strap retainer 2 may be optimized to meet or exceed prevailing ASTM retention requirements while in its locked position while still allowing the chin strap retainer to freely slide when pivoted to its position. This optimization consists of selecting the cross-sectional thickness of the cross members 32, 34 and 36, and well as the spacing between the cross members, based on the thickness (and to some extent the width) of the strap elements 22 and 24. By way of example only, consider a circular implementation of the chin strap retainer 2 such as that shown in

If desired, the decorative cap 70 could include additional clips for attachment to the frame 30, such as side clips that respectively engage the inner side 40 of the frame's left end 52 and right end 54. A further alternative would be to provide clips on the decorative cap 70 that releasably engage the outer side 42 of the frame 30 and do not contact the frame's inner side 40. Note that both of these attachment alternatives would allow the apertures 60 and 62 to be eliminated to the extent that no clipping is required on the inner side 40 of the frame's upper and lower ends 48 and 50.
By using any of the foregoing attachment schemes, the decorative cap 70 can be readily mounted on, and dismounted from, the frame 30. This enables manufacturers to provide a variety of decorative caps 70 of unique appearance that wearers can acquire in order to customize their headgear to suit different occasions. Manufacturers can also utilize different decorative caps 70 hearing customized trademarks and logos. Permanently mounted decorative caps could also be used.
Accordingly, a chin strap retainer has been described. The chin strap retainer, by virtue of its design, is durable, easy to operate, and allows decorative elements to be attached to the headgear on which the retainer is used. While various embodiments have been disclosed, it should be apparent that many variations and alternative embodiments would be apparent to those skilled in the art in view of the teachings herein. For example, in alternative constructions of the chin strap retainer 2, the frame 30 could be noncircular in overall shape. Non-circular cross-sectional shapes could also be used for the frame 30 and/or the cross members 32, 34 and 36. Moreover, the cross-sectional size and configuration of any given one of these elements need not be uniform. For example, the cross-section of the frame 3 could be thicker near the cross member 32 and thinner near the cross members 34 and 36, and visa versa. The same is true for the cross members 32, 34 and 36. Whereas the cross member 32 is preferably of uniform cross-sectional size and shape because it engages the strap elements 22 and 24, the cross members 34 and 36 could be of any shape, including irregular shapes of varying cross-sectional size.
It is understood, therefore, that the invention is not to be in any way limited except in accordance with the spirit of the appended claims and their equivalents.
