The invention relates to a headband. In certain embodiments, the invention relates to an apparatus having an elastic portion allowing the apparatus to fit a wide range of sizes. More particularly, the invention relates to a wide headband and further relates to a crescent-shaped headband.
Many items that are intended to fit on objects of different sizes use elastic to achieve that feat. For example, a headband that is meant to fit many different head sizes may be formed, at least partially, from an elastic material to enable the headband to automatically adjust to different size heads. One property of an elastic material is that it takes an increasing amount of force to stretch the elastic material an increased distance. To maximize wearer comfort and fit for wearers having very different size heads, some headbands include elastic around the entire circumference of the headband such that the headband stretches evenly and exerts even pressure on wearers having different head sizes. However, as the wearer puts the headband on, the circumference of the headband shrinks in the area of the headband in contact with the wearer's hair causing pulling and bunching of the wearer's hair. To prevent pulling and bunching of the wearer's hair, some headbands are formed from a length of inelastic material (e.g., fabric) intended to contact the wearer's hair and a length of elastic material intended to contact the back of the wearer's head. The ends of the inelastic material are attached to the ends of the elastic material to form the headband. This type of headband thus has a limited length of elastic material which will cause the headband to be looser on smaller heads and tighter on larger heads than a headband including elastic material about the entire circumference of the headband. Thus, while the headband can be used on different head sizes, it may be loose and fall off of smaller heads while being tight and uncomfortable on larger heads.
Elastic materials and bands formed partially of elastic material are used in other applications to achieve universal fit. For example, partial elastic materials are used in waistbands, shirt collars, hat sweatbands, masks, and eye patches.
It is further important for a wide headband to fit well and to look aesthetically pleasing on the head of the wearer. For thinner headbands (e.g., with a width of 1 inch or less), there is typically not a problem with the headband conforming to the shape of the head and appearing well-fitting. As headbands get wider (e.g., with a width greater than 1 inch), however, it is more difficult for the headband to conform to the shape of the head and lie flatly on the top of the head. One of the contributing factors to a wide headband fitting well and looking aesthetically pleasing on a wearer's head is the shape and size of the headband. Typically, a wide headband wearer desires a well-fitting headband that conforms to the head. A wide headband wearer also desires to avoid wrinkles and wishes to avoid any part of the headband “bunching up.”Many wide headbands have elastic to pull the headband toward the head and to prevent a loose fit, but while the elastic may be taut, the headband is not taut, causing it to “bunch up” or rise above the top of the head. This “bunching up can result in an ill-fitting headband causing an awkward feeling to the wearer. Wide headband wearers thus need a wide headband that will conform to the shape of the head over the entire surface of the headband.
In one aspect, an expandable joint includes a length of elastic material, a low-friction sleeve, and a headband body, such as a woven or non-woven fabric that forms a tube. The low-friction sleeve covers at least two opposing sides of a portion of the length of elastic material. The length of elastic material is affixed to the low-friction sleeve at a first end of the low-friction sleeve or a point adjacent to the first end of the low-friction sleeve. The length of elastic material extends beyond a second end of the low-friction sleeve opposite the first end of the low-friction sleeve. A fabric formed tube substantially encloses the low-friction sleeve. The low-friction sleeve is affixed to the tube at the first end of the low-friction sleeve or the point adjacent to the first end of the low-friction sleeve, and the length of elastic material extends beyond a first end of the tube.
In another aspect, a band operable to automatically adjust to a size within a range of sizes includes elastic material, a first low-friction sleeve, a second low-friction sleeve, and a tube. The length of elastic material has a first end and a second end. The first low-friction sleeve covers at least two opposing sides of a first portion of the length of elastic material adjacent the first end of the length of elastic material. The length of elastic material is affixed to the first low-friction sleeve at a first end of the first low-friction sleeve or a point adjacent to the first end of the first low-friction sleeve and the first end of the length of elastic material. The second low-friction sleeve covers at least two opposing sides of a second portion of the length of elastic material adjacent the second end of the length of elastic material. The length of elastic material is affixed to the second low-friction sleeve at a first end of the second low-friction sleeve or a point adjacent to the first end of the second low-friction sleeve and the second end of the length of elastic material. The tube has a first end and a second end, and the first and then the second and are not enclosed. The first low-friction sleeve is affixed to the tube adjacent the first end of the tube at the first end of the first low-friction sleeve or the point adjacent to the first end of the first low-friction sleeve. The second low-friction sleeve is affixed to the tube adjacent the second end of the tube at the first end of the second low-friction sleeve or the point adjacent to the first end of the second low-friction sleeve.
In one embodiment, a length of elastic material forms an expandable joint with a fabric to make an item including the expandable joint fit better on objects of different sizes. Unlike the traditional method of sewing the end of the elastic directly to the end of the adjacent fabric, in this embodiment, the elastic is sewn between two pieces of fabric at a point in the fabric away from the end of the fabric, wherein the fabric forms a tube substantially enclosing the length of elastic material. The end of the elastic material is encased in a small, semi-rigid plastic sleeve to prevent the fabric tube from bunching up around the elastic material when the elastic material is stretched. A headband including a pair of these expandable joints feels tighter on smaller heads and looser on larger heads, for a better overall fit than headbands employing the prior art method of sewing the end of the elastic material directly to the end of the adjacent fabric. The better overall fit also makes wearing the headband more comfortable. Although the example given is for headbands, the technology for connecting the elastic can be used in a wide range of items that use elastic to create an item with a universal fit including hat sweatbands, waistbands, shirt collars, etc.
In another aspect, a headband includes a headband body having a length and two ends. The headband body has an inner edge and an outer edge that are separated by a width. The inner edge of the headband body forms a curve and the outer edge of the headband body forms a curve. The curve of the inner edge of the headband body and the curve of the outer edge of the headband body have different radii from one another. The headband body is generally crescent-shaped. The ratio of the radius of the curve of the inner edge to the radius of the curve of the outer edge is greater than about 1 and less than about 6.
In another optional embodiment, a headband includes a headband body having a length and two ends. The headband has an inner edge and an outer edge that are separated by a width. The inner edge of the headband body and the outer edge of the headband body are substantially non-parallel. The headband body has widths at the ends and the center. The ratio of the center width of the headband body to the width at either the first end of the headband body or the second end of the headband body is greater than about 1.
Other embodiments result from a combination of the above embodiments and are further described and claimed below. Yet other embodiments evident from this disclosure will become apparent to the skilled artisan.
