8 Claims.

This invention relates to an improvement in a protective shield and more particularly to a face shield which may be mounted onto the frontal brim of a headgear and disposed at will either in a protective position close to the wearer or in a position in which the shield is completely removed to the underside of the brim.

It is among the objects of this invention to provide a face shield which is inexpensive, which is adaptable to be readily mounted onto a headgear, which is operable to be placed in a position of non-use and unobstruction to a position close to the wearer to afford maximum lateral protection and which can be conveniently and'readily moved from one position to another without requiring assistance or removal of the headgear.

A preferred embodiment of my invention is hereinafter described and is illustrated in the drawing in which:

Fig. 1 is a front face view of the embodiment and illustrates the shield in aprotective position;

Fig. 2 is a top plan view of the embodiment unmounted and in the position illustrated in Fig. 1;

Fig. 3 is a view of the unmounted embodiment in a folded position or the position when the shield is placed in'an unprotective position;

Fig, 4 is an end view thereof;

Fig. 5 is a rear view of the embodiment and its position illustrated in Fig. 1:

the support and engage the brim. This support is composed of two spaced rearward portions 7 I and 8 integral with the main or frontal portion of the support. Connected at the extremities of 5 these rearward portions are hinged members it and H, respectively, onto which is demountably attached a transparent flexible protective Shield 6. This protective shield can be made of any of the plastic materials such as the cellulose deriva- 10 tive materials or the phenolic resin materials or any other material that is sufliciently flexible and is suitably transparent for visibility.

A feature of this invention is that the protective shield l when mounted on to these hinged 16 members l0 and II can be moved from an unprotective or unobstructive position such as illustrated specifically in Fig. 3 and which is referred toas' a folded position in which the shield extends outwardly similarly to the supporti to 20 a protective or downward position and so that the shield is finally disposed closely to the wearer to afford maximum protection. This spacing is closer than can'be accomplished if the face shield were fixed and the headgear and shield slid down onto the head of the wearer. This function is accomplished principally by supporting the hinged members onto the ends of the rearward spaced portions of the support which are forwardly inwardly directed.

Fig. 6 is a sectional view taken along the line 0 lustrated specifically in Fig. 3 and the extent of VIVI of Fig. 5; and

Fig. 7 is a front elevational view of the protective shield. 7

While this invention is described in connection with providing a face-shield, it is to be under- 5 ends of these spaced portions, the engagcable j means attached to each of the hinged members.

stood that this'term is to be construed broadly and is to include any shield that aflords protection to any portion of the face such as eyes and such same construction is to be made when construing the breadth of the appended claims.

The type of shield contemplated is mounted onto a brim l of a headgear 2, which in this instance is illustrated as a protective cap such as a reinforced plastic cap. Should it be desired to apply the shield to a hat not having a rigid 4 brim, it would be necessary to add some means of reinforcement to the brim itself in order to maintain the support of the shield in an outwardly directed or horizontal position.

inward movement is illustrated by the angle A i which is the extent of inward disposition relative to a line transverse to the longitudinal direction of the support of the shield. By so arranging the 5 the central portion of the shield about the nose is bulged outwardly and conforms somewhat to the general contour of the face. This extent of bulge will depend upon the amount of free movement allowed in moving the pins l6 and IT to- The shield 3 includes the protective means or ward each other before engaging the inner extent face shield I and its support 5 which may be of metal or suitable material having sufllcient rigidity and attachable to the underside of the brim l- The support 5 is attached to the brim by means 20a and Zla of apertures 20 and 2|, respectively, provided in the shield and through which the pins pass. Figs. 3 and 5 illustrate this inward movement by the

vertical lines

30 and 3| which of rivets B which pass through the material of indicate this amount of inward movementwh n This mounting is il-- having enlarged heads and attached to.

respectively, are. moved inwardly or in the direction of each other the shield is moved from a horizontal or unobstructive. position to a downward or protective position.

For the purpose of convenience, in mounting the shield the outer extents 20b and lib of these apertures 20 and II, respectively, are enlarged to accommodate the enlarged heads of the pins and through which they can pass readily and for the purpose of holding the shield when the shield is in a flat unobstructive position, such as illustrated inFig. 3, it is advisable to space the larger portions of the apertures greater than the spacing of the pins when the hinge portions are in a similar'position so that the shield must be bulged slightly in order to insert the heads of the pins through the apertures so that when normally positioned the pins extend somewhat into.

the narrow portion of the apertures as illustrated.

The extent of bulge formed when. the shield is moved to a downward protective position will depend also upon the amount of inward disposition of the ends of the rearward portions 1 and 8 of the support 5, that is, the angle A. The greater this inward disposition the more the shield will be bulged outwardly assuming that the same length of apertures is provided in each instance.

In all applications of the invention, the angular disposition of the hinge members provides a "movement which can be utilized in obtaining a bulging action of the shield to conform to the face. Theangular disposition produces a transversemovement of the movable portion of each hinge membertowards the other. The members are appropriately attached to the shield and this transverse movement and consequent pressure is conveyed'to-the shield resulting in a bulge of the central portion. It is not'intended that this invention be limited to the construction wherein the attaching means abuts asurface of the shield. It is recognized that any'arrangement of assembly can be used ,wherein some pressure is exerted against-the shield, such as by the hingemembers being held in engagement with the shield durin movement so that the hinge members press secures the lower extent of the shield when placed in' a. protective position.

-.Anotlier fadvantage of this shield-ls the fact .that-it-can-be readily and conveniently moved from one position-to another and without re-- quiringany assistance or removal of the headgear. Also, by'this close disposition of the shield whenplaeed in protective position, it is effective in affording the maximum of protection the face or eyes such as may be accomplished in the use of goggles which fit closely to the face of the wearer." In order toposition the shield in either of the', two positions, a further feature is provided and consists of a means operative on the hinge to place a slight resistance to movement beyond the desired positions. This is illustrated in Figs. 2, 5 and 6. The central portions Ia and 8a of rearward portions 1 and 8, respectively, are separated from the portions. forming the hinge and they are disposed in engagement with the outer surface of engaged ends I! and 12a of g the hinged portions l0 and I I, respectively; cooperating to form the hinge connection. By making their outer surface of angular cross section, Fig. 6, the tension exerted on a flat surface of the engaged ends and against further turning by the extending portions la and 8a is suflicient to produce a looking or positioning effect of the shield. This function is very useful in the use of the shield because the face shield should beof improving vision, the hinged members can be made of some suitable transparent material such as the cellulose or phenol plastic material.

I have explained the principle and mode of operation of my invention, and have illustrated what I now consider to represent its best embodiment. However, I desire to have it understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically illustrated and described.

I claim:
