This invention relates to an eyeshield and it has to do more particularly with an attachment for a cap or the like in the form of an eyeshield which can be easily and quickly manipulated to its operative and inoperative positions.

More specifically, the invention is directed to an eyeshield which may be attached to the underside of the bill or brim of a cap or the like for protecting the wearers eyes from the glare of the sun. Although the invention may be applied to most any type of hat or cap, it is particularly useful on caps of participants in sporting events, especially baseball, for instance, where the playing conditions may be such that the shield must be snapped into or out of operative position easily and very quickly.

It is an object of the invention first of all to provide an improved eyeshield for a cap which is simple in its construction and, therefore, economical to make. It is also an object to provide an eyeshield constructed such that it may be readily applied to the usual cap without defacing the cap to any great extent. The shield is adapted to be secured to the bill of a cap and lie adjacent the underside of the bill when not in use so as to be out of the way and not interfere with the wearer's vision.

It is also contemplated to provide a shield which can be quickly and positively snapped to either the operative or inoperative position and retained in either position without resorting to complicated latch mechanisms. This is accomplished by employing over center spring means which controls the pivotal movement of the shield.

Although in the accompanying drawings there are shown several forms of the shield applied to a baseball cap, it will be understood that the invention is applicable to head gear in general and not merely the type of cap shown in thedrawings.

As is shown in Figure 1, the cap is of the usual type having a body portion I!) which fits over the head of the wearer and a curved bill H at the front which projects outwardly and serves to shade the wearers eyes. The shield of this invention is preferably attached to the underside of bill I! by a mounting plate 12 which extends forwardly from adjacent the rear edge of bill I l and which may be firmly attached to the bill as by rivets l3. Plate 12 may be conveniently stamped from sheet metal and is provided with a pair of depending ears l4 near its front end and a second pair of depending ears [5 spaced rearwardly of ears l4. Downwardly turned flanges 18 at each side of plate 12 may be formed to strengthen the plate and prevent it from flexing. At its front end plate [2 is provided with a curved brace ll which extends transversely of the plate and conforms to the arcuate contour of the bill ll. Brace 12 is secured to the bill by means of rivets l8 and serves to maintain the arcuate shape of the bill. At its inner or rear end plate I2 is formed into a downwardly projecting guard 153 which extends more or less parallel to the fore head of the wearer when the cap is adjusted on the wearers head.

vided with a notched-out portion 2i to accommodate the players nose when the shield is in the operative position shown by solid lines in Figure l. The shield is pivoted to plate 12 by means of a hinge plate 22 which may be riveted as at 33 to the central vertical portion of the shield. The upper end of plate 22 is formed into a pair of spaced ears 24 which are pivotally attached to the ears of plate 12 by a pin 25 passing through both pairs of ears.

The actuating mechanism for shield 20 comprises a coiled compression spring 26 which is housed within a tubular casing 21. At one end the tubular casing 2! is pivoted between ears 14 by means of a pin 29 and at the other end the casing is slotted as at 28. A second pin 30 extends across ears 24 on hinge plate 22 and is arranged such that when shield 20 is in the depending operative position, pin 30 lies forwardly of and below pivot pin 25. Pin 35 is slidably retained within the slotted portion 28 of the casing so that spring 26 is at all times compressed between the pins 29 and 30. It will be seen that by arranging pin 30 in this manner spring 2-5 functions as an over center spring. When shield 20 is pivoted from the position shown in Figure -5 to the position shown in Figure 4 pin 30 rotates upwardly about pin 25 and spring 23 is compressed until a point in the movement is reached where pins 25, 39 and 2 9 are all aligned in .a single plane, after which the distance between pins 29 and 30 becomes greater and the spring expands.

In the inoperative position shield abuts against ears I4 and a stop 3| on plate 12' limits the downward pivotal movement of the shield to a substantially vertical operative position as shown in Figures 1 and 4.

The shield may be shifted to the operative or inoperative positions by merely snapping .iteither upwardly or downwardly. When the shield is disposed in the inoperative position shown in Figure 5, spring 26 is above center and urges hinge plate 22 to its uppermost position with the shield 20 lying adjacent the underside of the bill. The shield is retained in this position since spring 26 is arranged tolbe under compression at all times. If it is desired to shift the shield to the depending operative position, it is merely snapped downwardly so that spring 26 assumes a position to the other side of center, that is, .to the position shown in Figure 4 with pin .3il lying below a line through pins and 29. During the first part of this movement pin 30 rotates down wardly and toward pin 29 thereby further compressing spring 25. After spring 25 passes-the center position, however, pin rotates downwardly and away from pin 29 thus allowing spring 26 to expand. The shield is thereby snapped downwardly abruptlyby the spring to the operative position, in which position the upper portion of plate 22 abuts against stop 3| to limit the pivotal movement of the shield to the depending position shown in Figures 1 and 4.

In Figures 7 to 10 there is shown a somewhat different form of operating structure which-results in a similar snap action of the shield to and from the operative position. As in theprevious structure described, a mounting plate 35' is utilized for attaching the shield to the bill of the cap. Adjacent the rear end of plate 35-a pair of depending ears 36 are formedon which'the hinge plate 31 and shield 20 are pivoted as by a pin 38 passing through wing formations 39 at the upper end of the hinge plate. The pivotal movement of the shield to and from the operative positions, shown bysolid lines inFi'gure' 9', is controlled by a spring-loaded leaf member 40 which is secured to mounting plate 35 at its front end. Leaf 49 extends rear-wardly of the bill-0f the cap and is fashioned so as to provide a down- :wardly offset portion 4| which is backed by a 4 spring 42 acting between mounting plate 35 and the upper side of the leaf portion 4|. If leaf 4!] is made sufficiently resilient, spring 42 may be omitted as is shown in Figure 10.

The snap action of this shield is obtained by means of a pin or roller 43 which is mounted between the upper ends of ears 39 and which bears against the spring-loaded leaf member 40. Pin 43 is arranged so that when the shield is in the operative position, the pin lies to the right of pin 38 as viewed in Figure 9 and when the shield is in the inoperative position, indicated by dotted lines in Figure 9, pin 43 is disposed, to the left of pivot 38. A stop 44 is arranged on leaf member 4| so as to engage pin 43 and limit the downward pivotal movement of the shield to the operative position as shown. In the inoperative position the shield abuts against and lies adjacent the underside of the bill of the cap.

The guard 45 fashioned at the rear end of mounting plate 35 may be provided with a rubber cushion 46 for further protection of the player.

It will be appreciated that the operation and action of the shield structure shown in Figures 7 through 10 is quite similar to that previously described. Assuming that the shield is in the folded or inoperative position and is desired to shift it to the operative position, the player merely snaps the shield downwardly and it automatically assumes the position shown in Figure 7. With the shield in the inoperative position pin 43 lies tothe left of pin 33 as shown by dotted lines at 41 and is urged downwardly by leaf member 45, which action assures the retention of the shield in the inoperative position until positively shifted by the player. As the shield is pivoted downwardly by the wearer, spring 42 is further compressed until pin 43 is over center, that, directly above pivot 38. Upon further downward movement of the shield pin 43 shifts to the other side of center position and spring 42 acting through leaf 45 snaps pin 43 downwardly and to the right until it abuts against stop 44 in which position it will be firmly retained by the tension in'spring 42. The action is simply in reverse when the shield is shifted from-the depending to the folded position.
