ARcHBoLD SAFETY HAT 2 Sheets-Sheet 2 Filed July l, 1959 INVENTOR. @A60/V AFCA/@o Unite States Patent O 3,016,541 SAFETY HAT Ralph L. Archbold, Euclid, Ohio, assigner to White Sewing Machine Corporation, Lakewood, Ohio, a corporation of Delaware Filed July l, 1959, Ser. No. 824,377 8 Claims. (Cl. 2 3) This invention relates to a safety headgear or head protective equipment, and more particularly to an improved harness or cradle attachment adapted to be detachably secured to a hard hatV or helmet and including a sweatband adapted to be replaced without removing the suspensionfrom the hat. g j

Numerous ,types of safety' headgear areavailable today comprising a protective hat provided with a harness for supporting the hat upon the head of a wearer. Some of such prior art devices employ la collarbutton type fastener for securing the harness onto the hat, the buttons having inwardly projecting heads which may exert pressure on the relatively soft or iiexiblerheadband material and against the wearer when the hat isfforced against the headband due to impact from a falling object or a sudden jolt. Also in certain prior art devices the sweatband is sewed or otherwise permanently secured to the headband portion of the harness requiring a new harness or at least the headband portion thereof when it is desired to replace a soiled or damaged sweatband. Replacement of a sweatband in such prior art devices requires detachment and subsequent attachment of the harness relative to the hat which is time consuming.

I have devised a harness, preferably formed of exible material such as a polyethylene plastic, -and comprising inverted generally V-shaped members easily attached to and detached from the hat by locking plugs formed on the outer face of the members which plugs engage holes in the hat lwhereby when the hat is forced against the headband only a relatively broad flat surface of the members contact the headband. The headband is formed of similar plastic material and has integral fingers extending upwardly through openings in the members, the iingers being attached to the upper ends of said members by a drawstring. To achieve stability of the hat relative to the harness certain of said openings -restrain shifting movement of the fingers and other openings permit limited movement of the ngers for adjustment of 'the' headband as desired. The sweatband is detachably secured tothe f headband portion of the harness lby a tongue and groove type arrangement whereby' the sweatband Vmay be attached and removed without ,disconnectingth'e harness from the hat. j l y It is the prime object of headgear of the type covered by this application to protect the individual wearing the hat or helmet from injury due to falling objects and the like. The problem which has confronted designers of this type of headgear is that of retaining the protective `features and, at the same time, providing headgear which is ventilated and comfortable to the wearer `and one wherein the harness may be easily adjusted to fit the head of the wearer. Most harnesses for headgear of the type described support the rigid hat or helmet in spaced relation to the head of the wearer. An acceptable harness should be constructed and arranged so as to permit some limited move-ment of the hat relative to the head of the wearer in response to impact. Certain of the prior art hats include a harness having depending peripherally spaced fingers wherein some of the fingers are connected to the crown of the hat and other fingers are connected to the headband. Such hats are characterized by a large number of separate locking pins extending normal to the head of the wearer for securing the parts in place. In Asuch prior art designs four pins have been used for conice nection with the headband and eight pins for connection to the crown. Such separate fastening pins present a costly problem in assembly and the rigid pins normal to the head of the wearer present a potential source of injury to the, wearer. Accordingly it is an object of my invention to provide a harness which will retain the comfort and safe-ty features of the prior art devices and one wherein no fastening pins normal to the head of the wearer are employed.

Another object of the invention is to provide an improved harness including a sweatband, the harness being adapted Vto be detachably secured to a hard hat or the like, and the sweatband removed from the harness without detaehing the harness from the hat. p

` Another object of theinvention is to Aprovide a harness of the above type which is economical to manufacture.

Another object of -the'invention'is Ito provide a harness 'of the'above type which can be leasily 1adjusted to different head sizes.

Referring to the drawings, the hat 6 is preferably formed of resin-bonded liber glass, although it may be made of metal or fiber. The hat 6 is provided with a series of spaced apertures near the juncture between the hat brim and crown. v The apertures 7 are shaped as best shown in FlG. 8 to receive a corresponding series of interlocking lugs such as 9 and` it? carried by the harness. The harness in its entirety is illustrated in FIG. 2 and comprises a headband indicated in its entirety as at il. The headband element 11 includes four spaced upwardly extending fingers 12, i3, 14 and l5 (FIG. 3). The finger i2 is located adjacent the headband portion i6 which is provided with a slot 17 and a locking button i8.

The upwardly extending finger 15 is located adjacent the other end of the headband which is provided with Va series of openings 20 and a T-shaped lug 21 as best 3 18 is pressed into one of the openings 20 and the headband is then retained in proper head size.

Each of the upwardly extending lingers 12l to 15 is adapted to have connected thereto an inverted V-shaped member. The V-shaped member 24 is assembled on the upwardly extending finger 15 by threading the iinger 15 over the lower bar 25 and under the middle bar 26 and thence upwardly where an opening at the apex of the member 24 is pressed over the pin or button 27. The button 27 may be integrally formed on the member 15, as shown in FIG. 3, or the button 27 may consist of a separate plastic headed fastener which is` apertured transversely as at 2S to receive a drawstring 29.

The harness is preferably molded of polyethylene plastic, although vinyl polymer material and other semirigid plastic material may be employed.

The V-shaped member 34, which is mounted on the linger 14, is similar to the V-shaped member 24 except that the opening between the bar 35 and the middle bar 36 is narrower than the opening whichv receives the iinger in the V-shaped member 24. The lowerend por tions of the member 24 extend outside of the headband 11 and are provided with integrally molded lugs 38 and 39. Each of the lugs 38 and 39 has a width corresponding substantially to the width of the spaced opening 7 in the hat so that the lugs 38` and 39 may be pressed through such opening 7 from the inside of the hat. Each of the lugs 38 and 39 has spaced parallel recesses 38a and 39a to provide a minimum `lug dimension between the recesses, which minimum width portion enters the reduced width portion 7a of the opening 7 in the hat.

The upwardly extending finger 13 of the headband is provided With a similar inverted V-shaped member 44 which is constructed and arranged substantially as the V-shaped member 34. The opening between the lower bar 45 and the middle bar 46 of lthe member 44 is like the opening in member 3-4 so that the finger 13 eXtending upwardly therethrough `is restrained against lateral shifting. The members 24 and 5 4 may shift witha in limits relative to the members 15 and 12 as limited by the Wide slotted openings in the members 24 and S4, respectively.

The linger 12 carried by the headband is provided with an inverted V-shaped member 54. The member 54 is in phantom outline in the illustration in FIG. 2 to per mit a clear showing of the member 44. The member 54 is provided with an opening between the lower crossbar and the middle cross-bar substantially as shown in connection with the V-shaped member 24. The width of the openings in V-

shaped members

24 and 54 allows the fingers 12 and 15 to be repositioned as the headband is adjusted to different sizes. Each of the inverted V- shaped members is provided with lugs such as the lugs 9-10-3839 to enter the openings 7 of the hat.

It will be understood that

members

24 and 54 are at the rear of the hat and that

members

34 and 44 are at the front of the hat. This provides for more flexibility at the rear of the hat and adds to the comfort and safety of the wearer.

The upper ends of the V-shaped

members

24, 34, 44 and 54 are each apertured and connected to their'respective ngers by a button 27, as shown in FIG. 1l. The button 27 is provided with a transverse bore 28- to receive the drawstring 29.

The

members

24, 34, 44 and 54 and their

respective fingers

15, 14, 13 and 12 are also connected by crossmembers 60 and 61. The members 60 and 61 are apertured at each end to receive the buttons 27. The members 60 and 61 along with the drawstring 29' permit an accurate and comfortable adjustment of the head harness as to height, whereas the headband 11 provides for cornfortable adjustment of the headband circumferentially about the wearers head. It will be observed that fingers 13 and 15 connected by l61 form a sort of transverse saddle over the head of the wearer. The lingers 12 and .14 along with 60 form a similar saddle. This double saddle arrangement is independent of the drawstring 29'. The harness height is easily adjusted by tying the drawstring 29 either tightly or loosely as required to lit the wearer. When the drawstring is tightened, the buttons 27 are drawn more closely together to decrease the harness height, and the cross-members 60 and 61, being exible, bow upwards as the distance between the op posed sets of fingers decreases. In this case, the crossmembers 60 and 61 serve to limit the distortion of the quadrilateral formed by drawstring 29, and further serve to insure the connection between the opposed lingers in case the drawstring should break or become untied.

The headband of the harness is provided with a sweatband 70 illustrated in its entirety in FIG. 5. The headband 11 has an integrally molded T-shaped channel 11a formed along the lower edge of the headband. The channel 11a provides a re-entrant T-shaped opening and the sweatband 70 is provided with a T-shaped rib 71 which is received by and frictionally held within the channel 11a. A flange 72 on the rib member 71 is stitched to the leather sweatband 70 as at 73.

It will be understood that the channel 11a is open at each end of the headband 11 so that the T-shaped rib 71 may be inserted through the open end and pulled along until the sweatband completely encircles the headband. When iinally assembled the sweatband 70 is turned upwardly within the headband as shown in FIG. 6.

f Although in the embodiment illustrated of my invention the

members

24 and 54 give greater flexibility at the rear of the hat relative to the harness than is provided by the

members

34 and 44, it Will be understood that all of the V-shaped members may be given greater liexibility relative to the hat by enlarging the slot which receives the headband finger. It will also be understood that the flexibility of the hat relative to the harness may be reduced by reducing the length of the slot at the lower portion of the V-shaped members.

The sweatband 70 may be replaced quickly and easily without removing the harness from the hat; the headband 11 may be adjusted to suit the wearer wi-thout removing the harness from the hat, and the vertical height of the harness may be varied by means of the drawstring 29 without removing the harness from the hat. The connection between the lower portion of the

harness members

24, 34, 44 and 54 and the hat is in the area between the headband and the hat. The members, such as 38 and 39, are integrally formed with the flat material of the V-shaped member so that impact of loads applied to the hat are transmitted through the relatively wide, at sections of the inverted V-shaped members and thence to the headband itself. Vertical loads at the top of the hat are applied to the V-shaped members through the medium of the lugs, such as 38 and 39, so that the V-shaped members are placed in tension and the pull imparted thereto is distributed by the members 60* and 61 and the drawstring 29 to the other portions of the harness. Preferably the lower portion of opposed harness members such as 44 include a slot 4 to receive a chin strap (not shown) for holding the hat on the wearers head.

It will be observed from FIGS. 2, 3 and 4 that the sweatband channel 11a terminates at 11b so as to provide a smooth overlap of the headband 11. The free end of the sweatband 70 is provided with an aperture 18a which is impaled on the fastening button 18 when the headband is in overlapped adjusted position.
