BYWMM United States Patent M 3,354,468 NAPE STRAP Charles E. Bowers, Jr., Newtown Square, Pa., assignor to The Fibre-Metal Products Company, Chester, Pa., a corporation of Pennsylvania Filed June 29, 1965, Ser. No. 467,868 Claims. (Cl. 2-3) This invention relates to improvements in hats and caps, and is especially concerned with unique means for retaining hats and caps in position on a wearers head.

While the device of the present invention is primarily concerned with a hat construction or attachment for use with a hat construction of the hard-shell type, such as industrial hard hats, and will be illustrated and described hereinafter with particular reference thereto, it is appreciated that the present invention is capable of many varied applications, all of which are intended to be comprehended herein.

In the customary usage of hard hats, such as have a hard outer shell, a flexible headband in spaced relation within the shell, and suspension means supporting the headband within the shell, as often worn by linemen, miners, and other such workmen, a wide variety of attitudes are assumed by the wearers head, some of which may tend toward inadvertent removal or falling of the hat from the head. A common position assumed by wearers of hard hats resulting in removal or loss of the hat from the wearers head is the simple act of bending over, say to look down, as through a manhole, or otherwise.

Accordingly, it is an important object of the present invention to provide a unique hat construction wherein a flexible back or nape strape is selectively engageable with the lower back of the wearers head or nape, to comfortably and effectively insure retention of the hat on the wearers head.

It is a further object of the present invention to provide an attachment strap of the type described for use in conjunction with conventional hats and caps.

The invention further contemplates the provision of a hat construction or attachment therefor having the advantageous characteristics mentioned in the preceding paragraphs, which is extremely simple in structure, easy to use, durable and reliable throughout a long useful life, and which can be selectively employed with existing hats requiring little or no modification thereof.

Other objects of the present invention will become apparent upon reading the following specification and referring to the accompanying drawings, which form a material part of this disclosure.

The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts, which will be exemplified in the construction hereinafter described, and of which the scope will be indicated by the appended claims.

FIGURE 12 is a transverse sectional view taken generally along the line 1212 of FIGURE 7.

Referring now more particularly to the drawings, and specifically to FIGURES 1 and 2 thereof, a hat is there generally designated 20, and may include a generally semispherical outer shell 21, say of plastic or the like. Interiorly of the shell 21 is secured a suspension harness 22, say of the type disclosed in U.S. Patent No. 3,026,523, or other suitable suspension means. The particular illustrated suspension harness 22 includes a plurality of circumferentially spaced outer legs 23 secured to the inner surface of the shell 21, and an additional plurality of circumferentially spaced inner legs 24 spaced within the shell. A generally annular headband 25 is connected at circumferentially spaced points thereabout to the inner legs 24, and thereby supported spacedly within the shell 21. In use, the suspension or harness 22 seats comfortably on the wearers head, see FIGURE 1, and the headband 25 extends circumferentially about the head to support the shell 21 in spaced relation about the wearers head and the headband 25.

In accordance with the instant invention, a nape strap or attachment, generally designated 30, is of elongate, flexible character and extends generally along the rear or back of the headband 25, with opposite end portions 31 each pivotally connected, as by a button or pin 32 to a respective adjacent side of the headband 25. The strap 30 is thereby mounted for swinging movement between an upper, retracted inoperative position, shown in dotand-dash outline in FIGURE 1, and a lowermost, extended operative position, shown in dashed outline.

The overall configuration and arrangement of strap attachment 30 is best seen in FIGURE 3. The strap may include a generally straight medial portion 34 having its lower edge 35 of outwardly bowed or convex configuration symmetrical about a transverse center line. From opposite ends of the medial portion 34, the strap may extend outwardly and slightly obliquely upwardly, as at intermediate portions 36, and thence outwardly and slightly obliquely downwardly, as by terminal portions 37. In practice, the strap 30 may advantageously be fabricated of flexible, resiliently defiectable material, such as plastic, or other suitable material. On one surface of the medial strap portion 34, the inner surface in its assembled condition, there is advantageously provided a pad 38 of soft, preferably resilient cushioning, such as plastic foam, or the like. The terminal portions 37 of the strap 30 are each provided with a series of thru holes 3" or'apertures 39, each' such' series being" arranged in a row extending longitudinally of the respective terminal portion and oblique to the longitudinal dimension of the strap. An additional thru hole or aperture 40 may be provided in each terminal portion 37 below and out of line with the adjacent series of apertures 39.

As best seen in FIGURES 4, 5 and 6, the strap 30 may advantageously be molded, or otherwise formed with a peripheral head or rib 42 extending entirely about the strap on the outer face thereof. Also, the strap region of each terminal portion 37 formed with the row of apertures 39 may be thickened, as by an interrupted bead or rib 43. The beads or

ribs

42 and 43 afford additional strength and effectively resist rupture without appreciably increasing weight or reducing flexibility. In addition, on the inner surface of the strap 30, surrounding the pad 38 may be a relatively small locating head or ridge 44. The pad 38 is thus more effectively retained in position on the medial strap portion 34 by the retaining action of ridge 44, together with suitable intersurface adhesive.

The headband 25 includes an elongate flexible strap 46, see FIGURE 8, bent to an annular configuration and having overlapping inner and

outer end portions

47 and 48 at the back of the hat. The strip 46 may be covered on its inner side with a sweatband '49 advantageously having a foam lining 50. The sweatband 49 may be secured to the strip 46 by having one longitudinal edge portion 51 of the sweatband folded upward about the lower edge of strip 46 onto the outer surface thereof and secured thereto, as by stitching 52. At spaced locations about the strip 46 there are provided apertures receiving buttons 53 for attachment to the suspension 22. Additional buttons 54 extend through the overlapping

end portions

47 and 48. The buttons-53 and 54 may be similar to conventional collar buttons, including a' shank and endenlargements or heads on opposite ends of the shank.

The pivot members 32-at opposite sides of the headband 25' may be of similar collar-button-type structure, each including a shank 56, an enlarged, relatively large inner head 57, and an enlarged, relatively small outer head 58. The, shank 56 of each button 32 extends through a respective terminal strap portion 37, through a selected one of the apertures 39', and through the-adjacent portion of stI'i-p'46. The inner head 57 lies on the inner side of strip 46 and the outer head 58 on the outer side of terminal strap portion 37. Adjacent to and spaced rearward from each button 32, there is provided extending through the strip 46 an additional button 60,*which may also be of collar-button-type stnucture. As'shownin'FIGURES 7-9, the button 60 passes througb'the' strip 46 and also through aperture 40 of the adjacent terminal strap portion-37, with its end enlargements:onopposite sides of'th'e' strip and terminal strap portion. This is the condition shown in dot-and-dash outline in FIGURE 1, with the strap 30 retained in its retracted'position against swinging movement about the pivots 32. In this condition, the nape strap 30 is located in the spacebetweenthe headband 25 and shell 21. In this inoperative conditionnoextr-a space is required for storage of the strap 30. In the event that relatively frequent swinging movementof'the'st'rap 30 be tween its retracted and extended positions isdesire'd, the use of the buttons 60 may be avoided and the strap swungto its retracted position with thecushion or pad 38frictionally engaging the rear side of'the headband and retaining the nape strap in retracted position. When use of'the nape strap 30 is desired, it is thenonly necessary to pull the strap down to'its comfortable position with the cushion or pad engaging the lower back portion ofthe wearers head.

The effectivelength of the nape strap 30 maybe readily adjusted by insertion of the buttons or pins 32 in' selected apertures 39. For example, in FIGURES 8 and'9' the button 32 passes through one aperture 39 while in FIGURE the button 32. passes through another aperture 39 for longer effective length of the nape strap. Also, while the nonaligned aperture 40 may be employed to positively retain the nape strap 30 in its retracted, nonuse position, as described above, the buttons or pins 60 may be engaged in one of the apertures 39 to hold the nape strap against rotation while in an extended or operative position. This condition is shown in solid lines in FIGURES 1 and 10.

Obviously, with the nape strap 30 swung to its extended position and conformably engaging about the lower back of a wearers head, substantial resistance is provided against removal of the hat by any force having a forward component.

From the foregoing, it is seen that the present invention provides a hat construction or attachment which fully accomplishes its intended objects and is well adapted to meet practical conditions of manufacture, installation and use.

Although the present invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it is understood that certain changes and modifications may be made within the spirit of the invention and scope of the appended claims.
