FACE SHIELD AND ADJUSTABLE HEAD BAND THEREFOR Filed Feb. l5, 1956 (Afl,

FACE SHIELD AND ADBUSTABLE HEAD BAND THEREFOR Robert Malcom, Jr., Chicago, 1li., assigner to Chicago Eye Shield Company, Chicago, lll., a corporation of Illinois y Application February 15, 1956, Serial No. 565,572 11 Ciaims. (Cl. 2 9) The principal object of this invention is to provide an improved face shield and adjustable head band therefor, wherein the transparent face piece may be quickly and readily releasably secured to thev brow piece of the face shield, wherein relative thermal expansion and contraction between the face piece and brow piece is provided even though the two pieces are firmly secured together, wherein the face shield is pivotally mounted on the head band in a simple manner to allow easy manipulation of the face shield, wherein the head band is quicklyv and readily adjusted to t the head of the wearer, and wherein the head band is soft and exible withl no metal parts touching the head of the wearer so as to provide maximum comfort.

' Further objects of this invention reside in the details of construction of the face shield and adjustable headband and in the co-operative relationships between the cornponent parts thereof.

Other objects and advantages of this invention will become apparent to those skilled in the art upon reference to the accompanying specification, claims and drawing in which:

Fig. 1 is a perspective view of the face shield and adjustable head band of this invention applied to the Wearers head.

Fig. 2 is a perspective View of the adjustable head band illustrating the manner of adjusting the same.

l Fig. 3 is a perspective view of a portion of the adjustable head band illustrated in Fig. 2 but showing the same in adjusted position.

Fig. 4 is a horizontal sectional view taken substantially along the line 4 4 of Fig. 3.

Fig. 5 is a vertical sectional view taken substantially along the line 5 5 of Fig. 3.

Fig. 6 is an exploded perspective view of a portion of the head band and face shield illustrating the co-opcrative relationships between the parts thereof. Fig. 7 is a vertical sectional view through the face shield taken substantially along the line 7 7 of Fig. l.

Fig. 8 is a vertical sectional view taken substantially along thel line 8 8 of Fig. l.

. Fig. 9 is a vertical sectional view taken substantially along the line 9 9 of Fig. 1.

The face shield and adjustable head band of this-invention `are generally designated at 10 and 11, respectively.v The face shield 10 includes a curved brow piece 12 having a curved portion at the bottom thereof, the

such as aluminum or the like. Rivets 19 extend through the holes 17 in the brackets 16 and through the brow piece 12 for securing the channel member 13 to the brow piece 12. Intermediate its ends, the inner leg 14 is alsoV provided with a pair of holes through which rivets 20 extend, also for securing the channel member 13 to the brow piece 12. The outer leg 15 of the channel member 13 is provided with holes 21 in alignment with the intermediate rivets 20. A pair of spring members '23 provided with holes 24 are secured in place on the brackets l 16 by the rivets 19, which secure the brackets 16 tothe brow piece `12 being relatively stii and preferably being formed from plastic impregnated paper board or the like.`

brow piece 12, and the outer free ends of the spring members 23 are provided with inwardly facing buttons 25 which, in turn, extend through'the holes 26 in' the outer leg 15 of the channel member. By manipulating the spring members 23, the buttons 25 may be inserted through and drawn from the holes 26. v

A resilient transparent face piece 28, which may take the form of a suitable transparent plastic sheet, has its upper edge closely received inthe channel member 13. The face piece 28 is provided adjacent its ends with a pair of slots 29 which are in alignment with the pair of holes 26 in the outer` leg 15 of the channel member 13. When the buttons-25 on the spring members 23 are inserted through the holes 26 in the channel member 13, they are alsoy snapped through the slots 29 in the tace piece 28 for releasably securing the face piece 28 in place in the channel member 13. By reason of the slots 29 the face piece 28 and the channel member 13 are allowed to expand and contract with respect to each other so that thermal expansion and contraction conditions will not operate to distort or buckle the face piece 2 8. When the face piece 28 isinserted in the channel member 13, it is deformed slightly between the intermediate rivets 20 and the 'aligned holes 21 in the outer leg 15 of the channel member 13, which also operates releasably to secure the face piece 28 in the channel member 13. In this way, the face piece 28 is quickly and'readily releasably secured in the channel member 13 and, hence, to the brow piece 12, and replacement of face piece is readily accomplished.

The adjustable head band ll'includes `an open ended flexible sleeve 32 which is preferably formed of a soft llexible plastic material.V This sleeve 32 has an inner wall 33 and an outer wall 34. The outer wall 34 ofthe sleeve is provided intermediate its ends with a pair of spaced-apart transverse slits 35, these slits dividing the sleeve into a central portion between the slits and side portions between the ends of theisleeve and the slits. An outwardly facing button 36 is secured to the outer wall 34 of the central portion ofthe sleeve between the slits 35. A flexible strap 38, preferably formed of a soft flexible plastic material, extends between the open endsl of the sleeve 32 and has two ends 39 and 4l). The end 39 of the strap 3S is threaded through one side portion of the sleeve 32, through one slit 35, over the outer wall 34 of the central portion of the' sleeve, and through the other slit 35 into the other side portion of the sleeve 32. Inv a like manner the other end 40 of the strap 38 is threaded through said other side portion of the sleeve 32, through said other slit 35, over the outer wall 34 of the central portion of the sleeve, and through said one slit 35 into said one side portion of the sleeve 32. The ends 39 and 4t) of the strap overlap each other and, as illustrated herein, the end 39 of the strap lies inwardly from the end 40 of the strap. The ends 39 and 40 of the strap 38 are each provided with a plurality of longitudinally spaced holes 41, which selectively receive the outwardly facing button 36 carried by the outer wall 34 between the slits 35. By inserting the button 36 through the desired holes 41 in the strap ends 39 kand 40, the

encircling length of the strap 38 is quickly and readily adjusted.

The face shield is pivotally mounted on the adjustable head band 11 and this is accomplished by passing rivets through the outer wall34 of the sleeve 32 adjacent the ends thereof and the holes 18 in the brackets 16.1 Washers 44 and 45 are arranged ontV opposite sides of the vbrackets 16 and are drawn up snugly by the rivets 43 so as to provide a frictional type of pivoting action. By reason of these pivotal connections between the adjustable head band 11 andthe face shield 10, the face shield may be readly'manipulated with respect to the face of the wearer.r Since the adjustable head band 11 is soft and liexible and since there are no metal parts ,which can touch the head of the wearer, the face shield andadjustable head band of this invention may be worn 'with maximum comfort.

While for purposes of illustration, fone form of this invention has 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.
