This invention relates to an improved shield.
One object of the invention is to provide a shield having a shield element comprising a single arcuate transparent sheet which will effectively protect the face of the wearer from in- Jury from flying particles.
Another object of the invention is to provide a shield wherein improved hinge structure is utilized for mounting the shield element for swinging movement on the frame employed, so that said shield element may be conveniently moved into and out of shielding position.
A further object of the invention is to provide a shield which will be extremely durable and light in weight and which will be highly eificient in use.
With the above and other objects in view, reference is now had to the accompanying drawings, wherein:
Figure 1 is a perspective view of our improved shield, showing the shield element in lowered position,
Figure 2 is a vertical sectional view of the shield, with the shield element in lowered position, said shield being shown, in dotted lines, in raised position,
Figure 3 is a transverse sectional view of the shield,
Figure 4 is an enlarged detail sectional view on the line 4-4 of Figure 1 looking in the direction indicated by the arrows,
Figure 5 is a detail plan view of the adjusting means employed,
Figure 6 is an enlarged detail sectional view on the line 6-4 of Figure 5,
Figure 7 is an enlarged detail sectional view on the line ll of Figure 5, and
Figure 8 is an enlarged detail sectional view on the line 8-8 of Figure 3.
Referring now more particularly to the drawings, wherein similar reference numerals designate like parts throughout the views, the numeral I indicates in general the frame of our improved shield. The frame I includes a substantially circular head band 2 having free end portions 3 and 4 which are disposed at the rear of the frame I. As best seen in Figure 5, the free end portions 3 and 4 are adjustably connected by means of a strap 5, which strap has one end portion secured to the portion 4 and the other end extending in overlying relation to the portion 3. The strap 5 is formed with a longitudinal slot 6 which extends throughout substantially half its length. The strap 5 extends through a clip 1, carried on the portion 3 swinging relation.
of the band 2, and said strap also has extending through the slot 8 thereof a clamping bolt 8 on which is screwed a wing nut 9. A washer ID is carried between the wing nut and the surface of the strap 5,. In order to provide a reinforcement for the strap 5 beneath the washer In, a plate I l is used, and this plate is held in place on the portion 3 of the strap 2 by means of rivets l2. It will be seen that the clip I retains the strap 5 connected to the portion 3 at all times and that, by tightening the wing nut 9, the strap 5 may be held in an adjusted position at any point along the slot 6. The band 2 may thus be adjusted to suit various head sizes.
Connected to the band 2 and extending diametrically thereof is a transverse head-piece l3 which will, of course, fit over the top of the head. The piece i3 is formed of such material as to insure comfortable wearing of the frame. The head-piece I3 is held at its opposite end to diametrical portions oi. the hand 2 by means of rivets l4 and IS.
The rivets l4 and i5, as will be seen clearly in Figures 1, 3 and 4 of the drawings, also secure U-shaped hinge pieces I8 and l! to the frame I. The U-shaped hinge pieces l6 and i! are formed of resilient metal and serve the purpose of hingedly and resiliently connecting the shield element frame, indicated at l8, to the frame I. The shield element frame, as will be seen in Figures 1 and 3, is substantially semicircular in top plan. This frame [8 is formed of fiber, metal, or other suitable material. The opposite corresponding ends of the frame i8 are hingedly and resiliently connected with the outer legs of the hinge pieces [6 and i! by bolts I 9 and 20. More specifically, said bolts extend through the outer legs of the hinge pieces [6 and i1, through the opposite corresponding ends of the shield element frame it, and through enlarged openings in the shield element, to be hereinafter described. Nuts 2| and 22 are car ried on the end of each bolt and firmly lock said bolt, together with the other elements, in Disposed between the inner faces of the corresponding ends of the frame [8 and the outer legs of the pieces l6 and I! are pairs of spring washers 23, and mounted between the outer surfaces of the ends of the frame l8 and the nuts 2| are pairs of spring washers 24. The pairs of washers 23 and 24, together with the U-shaped hinge pieces 16 and I1, will provide a resilient connection between the shield element frame l8 and the frame i.
Mounted on the shield element frame I 8 is an arcuate transparent shield element 25 which is preferably formed from heavy celluloid, although it will be readily understood this shield element may be made from any transparent bendable material. The shield element 25 has a straight upper marginal portion 26 which is secured to the frame I8 by means of screws 21. The shield element 25 also is formed with a curved edge 28 which extends throughout the major portion of the periphery of said shield element. As hereinbefore described and shown particularly in Figure 4, the shield element is formed with openings 29 through which the bolt 20 and nuts 2i and 22 extend. The shield element 25 is of sumcient length so that, when in lowered position, it will completely cover the face of the wearer and protect it from flying particles of metal or other material.
In order to cushion the head of the wearer, we provide a sweat band or cushion 30 which extends about the inner surface of the band 2 throughout substantially half its circumference. The band is removably held in place by means of a plurality of mating straps 3| having snaps 32 connected therewith. It should be understood that the use of the band 30 is not entirely necessary and that any other substitute therefor may be employed, as desired. The band 30 will, of course, be of soft material so as to prevent abrasion of the head of the wearer by the band 2.
It is believed that the manner of using our improved shield will be thoroughly understood. However, a short statement is not thought to be out of place. The device is placed on the head with the band surrounding the forehead and temple and the strap l3 over the top of the head. In this position, the shield element 25 will be, in lowered position, disposed before the eyes and face of the wearer. In this position, any particles coming from the front or either side will be prevented from reaching the head and face. When it is de is of transparent bendable material and which pieces I6 and i1 and the bolts 20 providing the necessary pivots. The shield element 25 may be removed from the shield element frame i8 merely by removing the bolts 27. The entire shield ele ment and frame may be removed from the frame or head-piece i by removing the bolts 2i and 22, and the spring washers 24.
Attention is particularly directed to the fact that we employ a one-piece shield element which may be readily replaced when necessary. It is also desired to call attention to the fact that the entire shield is light in weightand extremely durable in construction.
Having thus described the invention, what is claimed as new is:
1. In a shield, a frame having a band and a head-piece, U-shaped hinge pieces, means connecting the head-piece with ends of each of the hinge pieces at diametrical points of the band, a shield element frame, bolts, spring washers on the bolts and resiliently connecting said bolts with the shield element frame, and a shield element carried by said shield element frame, said shield element and shield element frame being movable on the bolts and hinge pieces from lowered operative position to raised inoperative position.
2. A shield as recited in claim 1, wherein said shield element comprises a single piece of transparent material arcuate in cross section, said shield element having a straight marginal portion and a curved periphery, and means removably connecting the straight marginal portion with the shield element frame, said shield element frame reinforcing the shield element.
