HEADGEAR WITH RETRKCTABLE EYE SHIELD Filed Oct. 27, 1955 2 Sheets-Sheet 2 INVENTOR. J/rc/(sm/ A. 4/150 T/mww United States Patent Oi HEADGEAR WITH RETRACTABLE EYE SHIELD Jackson A. Aileo, Carbondale, Pa., assignor to Leonard P. Frieder, Great Neck, N. Y.

This invention relates to a headgear having a retractable eye shield. It is illustrated herein as applied to a helmet of the type worn by aviators and others engaged in hazardous occupations, and it has particular advantages when used in connection with such helmets. However, in its broadest aspects, the invention has substantial utility in connection with other types of headgear.

It has been proposed to provide a safety helmet or other headgear of generally similar nature, with an eye shield movable between a shielding position in front of the wearers eyes and a retracted position above the crown of the headgear.

An object of the present invention is to provide a headgear of the type described, including a simplified eye shield structure.

Another object is to provide a combined headgear and eye shield structure including improved latch means for holding the eye shield in either of its shielding and retracted positions, and improved means for releasing the shield from the latch means so that it may be quickly and easily moved from one position to the other.

The foregoing objects of the invention are attained in the embodiment of the invention described in detail herein. This embodiment includes an eye shield in the form of a sheet of plastic material bent to form a generally semi-cylindrical central portion and having a pair of integrally formed wings which extend rearwardly along the sides of the headgear. The shield is pivotally mounted on pivot pins which extend through slots in the shield, so that the shield is slidable on the pins as well as being rotatable about the pins. Springs are provided between the pins and the shield, biasing the shield to a latching position in which the pins are at one end of the slots, and the wings engage stop members fastened on the side of the helmet, which sto'p members are effective to prevent rotation of the shield on the pins. By sliding the shield along the pins, the wings can be moved away from one of the stop members, and may thereafter be rotated about the pins to swing the shield from one of its positions to I the other.

Other objects and advantages of the invention will become apparent from a consideration of the following description and claims, taken together with the accompanying drawings.

In the drawings:

In the drawings, there is shown at 1 a safety helmet having a rigid outer shell, This helmet may be of the type described in detail and claimed in the copending application of Leonard P. Frieder and Walter S. Finken, Serial No. 201,904, filed December 21, 1950, entitled, Headgear Structure, now U. S. Patent No. 2,739,309, issued March 27, 1956.

Mounted on the helmet shell 1 is an eye shield generally indicated by the reference numeral 2 and preferably formed from a single sheet of plastic material. The central portion of the shield is generally cylindrical in contour, and terminates at the sides in a pair of integral rearwardly projecting wings 2a. The upper and lower edges of the shield 2, at the central portion thereof, are provided with forwardly projecting tapered flanges 212, whose function is to deflect forwardly air moving off the edges of the shield and thereby to prevent the carrying of particles into the space behind the shield.

Each of the wings 2a is provided with a central elongated slot 2c which extends horizontally when the shield is in the shielding position as shown in Fig. 1.

Mounted on each side of the shell 1 is a pivot pin 3 shown as a bolt held in place on the shell 1 by means of a nut 4. Fixed on the shield 2 is another bolt 5, the bolt 5 being spaced horizontally forward of the pivot pin 3 when the shield is in its shielding position. The bolts 3 and 5 hold spring retainer plates 6 and 7 in place on the shell, the plates 6 and 7 being apertured to receive the ends of a coil spring 8.

A pair of stop members 9 and 10 are attached to the sides of the shell 1 by means of screws 11. The details of the stop members 9 and 10 are best seen in Figs. 4

and 5. As there shown, each of the stop members comprises a body portion through which the screws 11 extend and an upwardly projecting flange 9a or 10a at the upper end of its outer side. The upper ends of the body portions inside the flanges 9a, 10a are rounded, as shown at 12 in Figs. 4 and 5.

Mounted on the shell 1 by any suitable means is another stop member 13, of any suitable construction. Stop member 13 is located somewhat above the upper edge of the wing 2a when the parts are in the positions shown in Fig. 1. The helmet shell 1 is generally hemispherical, as shown in the drawings, and the pivot pins 3 are aligned with the horizontal transverse, i. e., left to right) axis of the hemispherical shell.

Operation The shield is shown in full lines in Fig. 1 in its shielding position. The springs 8 are then effective to bias the shield 2 rearwardly, thereby holding the forward ends of the slots 20 against their respective pins 3.

When it is desired to move the shield from this position to the retracted position shown in full lines in Fig. 3, the shield is first moved forward against the springs 8 from the full line position of Fig. 1 to the dotted line position shown in that figure. This movement carries the lower sides of the wings 2a out of engagement with the rear stop member 9, so that the bolt 2 is then free to pivot upwardly about the pins 3, the direction of movement be ing indicated by the arrow 14 in Fig. 1. As this movement continues, the shield moves to the dotted line position of Fig. 3. When the wearer releases it in that dotted line position, the springs 8 move it downwardly to the full line position of Fig. 3, moving the ends: of the wings 2a into engagement with the stop members 9 and It). The shield is thereby latched in its retracted position. The upward and rearward movement of the shield 2 on its pivot pins is limited by the stops 13 so that the wearer knows when he has moved the shield back far enough so that upon releaseit will drop into the proper position with respect to the stop members 9 and 10.

When it is desired to move the shield from the retracted position to the shielding position of Fig. 1, the operation is just the reverse 'ofthat described. Briefly, the shield is first lifted upwardly to the dotted line position of Fig. 3, and then is rotated forwardly about the pivot pins 3 until it reaches the dotted line position of Fig. 1. The shield is released in that position whereuponthe springs 8. carry it back to the full line position of Fig. 1.

It may be seen that thelatching and latch releasing arrangements shown are very simple and that the latch and latch releasing operations may be carried out easily by one hand of the wearer, and without careful attention to themanipulation of the shield.

Furthermore, the manipulations of the shield are not accompanied by contact between two metallic members. The stop members 9 and 10 are preferably made of plastic material, as is the shield 2 and the helmet shell 1. In certain eye shield and headgear structures of the prior art, metal latching members come into engagement with a substantial impact at each latching or unlatching of the shield. Where the headgear is a rigid shell, such an operation of abutting metal members results in a clashing or clanging of the metal parts which echoes inside the shell and is very distracting to the wearer. By constructing these parts of plastic material as described above, this echoing action is prevented.

Although the eye shield and its latching means are shown as mounted on a rigid shell, they are readily adaptable to mounting on other types of headgear having a relatively soft outer covering. The eye shield 2 of plastic sheet material is readily deformable and adaptable for use with such a head covering.

While I have shown and described a preferred embodiment of my invention, other modifications thereof will readily occur to those skilled in the art and I therefore intend my invention to be limited only by the appended claims.
