3,047,876 Patented Aug. 7, 1962 ice FIG. 14 is a perspective view illustrating one kind of protective lface piece or the like which supported by the adjustable head piece.
Referring first to FIGS. l, 2 and 8, one lform of the `adjustable head piece of this invention is generally designated at 10. It includes an elongated molded synthetic plastic strip 11 which is preferably injection molded from a high impact synthetic plastic material, such as high Itensile strength nylon or modied polyethylene or the like. As shown more clearly in FIG. 8, the synthetic plastic strip 11 includes an elongated and upwardly curved central section 12 and elongated and downwardly curved end sections 15, the end sections 15 being downwardly offset from the central section 12 as illustrated at 16. This elongated strip 11 is bent into a substantially circular head band with the downwardly offset sections 15 overlapping. The central section 12 of the strip forms a front portions 13 and side portions 14 of the head band. The overlapping end sections 15 of the strip form a downwardly oliset rear portion of the head lband. Because the cent-ral section 13 of the strip is upwardly curved, lthe front portion 13 of the head band slants rearwardly to fit against the `forehead of the wearer when the strip is =bent into the circular shead band. This rearward slanting of the front portion of the head band causes the head band to fit flat against the forehead of the wearer, thereby providing maximum contact area and maximum comfort to the wearer. Because the end sections 15 of the strip are curved downwardly, they also slant rearwardly when they are overlapped to `form the rear portion of the head band. They also lit flat against the lower rear of the head of the wearer to provide maximum comfort. Because the overlapping end sections of Athe strip are oiset downwardly with respect to the central section of the strip they lie below the usual bump on the rear of the head of the wearer and this also adds greatly to the comfort afforded By reason of the upward and downward curvatures in the molded strip and the downward offsetting of the overlapping end sections a good `and comfortable fit to the head of the wearer is at all times assured.
The overlapping end sections 15 of the head band are eachprovided with a slot 17. One of the slots 17 having teeth 18 extending upwardly from the bottom edge therei of and the other slot 17 having teeth 18 extending downwardly from the upper edge thereof. The teeth 18 in the slots 17 `are preferably of the rounded type. The overlapping ends 15 of the strip are received in a molded synthetic plastic sleeve 20, this sleeve preferably being molded from nylon, modiiied polyethylene or the like. The sleeve 20 is rectangular in cross sectional configuration and internally is somewhat wider than the width of the overlapping end sections 15 of the strip as is illustrated r, more clearly in FIGS. 3 to 6. The sleeve 20 is preferably curved so as -to conform to the shape of the lower rear of the head of the wearer.
The front wall of the sleeve 20 is centrally provided with a square hole 21 4and the rear wall thereof is centrally provided with `a round hole 22. A rivet 23 extends through the sleeve 20 and it is provided with a square head 24 which is arranged in the square hole 21 in the sleeve. The other end of the rivet 23 extends outwardly through the round hole Z2. A washer 25 is carried by the rivet 23 `and it is `arranged between the front wall of the sleeve 20 `and the overlapping ends 15 of strip. A knob member 26 is also carried by the rivet 23 and it comprises -a knob portion 27, which is arranged rearwardly from the sleeve 20, and la gear 28 which extends through the round hole 22 and into the slots 17 in the overlapping ends 15 of the strip. The knob member is also molded from a suitable high impact synthetic plastic material. The inner end of the gear 2S lies `adjacent to the washer 25 and it is held 3 in place :by peening over the rear end of `the rivet 23 as illustrated at 34. The gear 2S is provided with rounded teeth 29 which 29 which mesh with the rounded teeth 18 in the slots 17 of the overlapping sections i4 of the strip 11.
Interposed between the rear wall of the sleeve 2% and the knob 27 is a spring detent Imember 3). This spring detent member 30 is provided with a pair of projections 31 which are received in holes in the rear wall of the sleeve 20, Ithe projections 31 and the holes preventing rotation of the spring detent member 3@ with respect to the sleeve 20. The spring detent member 30 is also provided with detent projections 32 which are selectively received in detent notches 33 in the knob 27. The detent projections 32 and the detent notches 33 operate to maintain the knob member 26 in whatever positions to which the knob member is adjusted.
By rotating the knob 27, the gear Zit is rotated and the teeth 29 thereof cooperate with the teeth l in the overlapping ends l5 to adjust the circumference of the head band so as to t the same to the head of the wearer. When the head band is adjusted to the desired position, it is maintained in that position by the detent means 30 cooperating with the knob 27. When the head band is tightened to a predetermined extent about the head of the wearer, the rounded teeth 29 on `the gear 28 cooperate with the rounded teeth 18 in the slots 17 `to expand the slots 17 so as to allow the teeth 28 to slip with respect to the teeth 1S. As a result the head band cannot be tightened too tightly and stripping of the gear teeth 29 and 13 is entirely prevented. By reason of this construction, the gear teeth 29 and 18 not only operate as an adjusting means for the head band but also operate as a clutch means to prevent tightening the band too much and to prevent stripping of the gear teeth.
In the molding of the synthetic plastic strip ll, the side portions -14 of lthe head band are thickened as indicated at 35 and are provided with upwardly and forwardly facing pockets 36, as shown more clearly in FIGS. 9 to l2. The outer edges of the pockets 36 are provided with upwardly extending tabs 37 and the outer walls of the pockets 36 have rivets 38 secured therein adjacent the tabs 37. A second synthetic plastic strip 39 has its ends received within the pockets 36, this strip 39 forming a cross Kband for the adjustable head piece. The ends of the strip 3S? are provided with a plurality of spaced apart holes di) which are adapted to selectively receive the pins 38. The pins 38 cooperate with the holes 4d in the cross band 39 for pivotally securing the cross band 39 at desired depths within the pockets 36. By manipula-ting the tabs 37, the insertion of the pins 38 in the selected holes 4t? is greatly facilitated. The pockets 36, in addition to receiving and concealing the ends of the cross band 39, also operate to limit the extent of pivotal movement of the cross band 39 and preferably the, pivotal movement is limited between a forward position as illustrated in FIG. l and a substantially vertical position as illustrated in FIG. 2. This limiting of theposition of the cross band `between these positions also adds greatly to the comfort afforded by the adjustable head piece. The cross band 39, as illustrated in jPiG. 7, may be made wider at its center than at its ends, as illustrated at el, so as to provide a large area `for contact with the top of the head. This adds still further to the comfort of the adjustable head piece when worn.
As shown more clearly in FIGS. 9 to 14, supporting means for supporting a protective face piece are also integrally molded on the side portions 14- of the head band, one form of such supporting means 4being illustrated in FIGS. 9 and l0 and other forms being illustrated in FIGS. 11 and l2 and 13. ln FIGS. 9 and 10a member d5 is integrally molded on the side portions 14 of the head band. This member 45 includes a pair of outwardly facing diverging legs 46 and also a cam projection 47 arranged therebetween and therebelow. The pair of outwardly facing diverging legs are adapted to receive a pair of diverging and opposed inwardly facing legs Si) formed on a clip 49 whichin turn is provided with a cam recess 5l. When the legs 5@ of the clip are rcmovably received over the legs t6 on the member d5, the cam recess 5l engages over Ithe cam projection 47 for maintaining the clip i9 on the member 45, the resiliency of the thermoplastic member 4S permitting this operation. The clip `t9 may be carried by any suitable protective face piece and in this connection the clip may be pivotally secured at 55 to a bracket 56 carrying the protective face piece or the like, such as a face shield having a brow portion S7 and a shield portion 58 as illustrated in FIG. 14. Other types of protective face pieces may be so supported, such as welding shields, goggles or the like.
in FIG. 11 the clip 49 with its legs 50 is secured by rivets 52 to a bracket 53, the rivets also securing in place a spring cam 54 on the clip 49. When the legs 59 of the clip 49 are removably received over the legs de of the member 45, a cam recess on the spring cam Sd engages over the cam projection 47 for maintaining the clip de on the member 45. Here, the bracket 53 connects the clip t? to any suitable protective face piece, as in FGS. l() and 14.
Another type of supporting means is illustrated in FIGS. l2 and 13. Here a member e@ is integrally molded on the thickened portion of the side portions 14 of the head band, the member `Sti providing an upwardly facing slot 6d. A clip 62 is removably received in the slot el and is provided with a pair of ribs 63 engageable on each edge of the slot 61 for releasably retaining the clip 62 in the slot 6d. The clip 62 may also support a protective face piece in the same manner as discussed above in connection with FIGS. 9 and l0.
While for purposes of illustration several forms of this invention have been disclosed, other forms thereof may become apparent to those skilled in the art upon reference to this disclosure and, therefore, this invention should be limited only by the scope of the appended claims.
