JOHN L MARCHELLO BY QulQmm w/w) @Qmz ATTORNEYS March 15, 1966 J. MARCHELLO SAFETY HELMET 2 Sheets-Sheet 2 Filed April '7, 1964 so I 32 \P INVENTOR.
JOHN L. MARCHELLO ATTORNEYS United States Patent 3,239,842 SAFETY HELMET John L. Marchello, Ann Arbor, Mich, assignor to Joseph Bnegeleisen Company, Southfield, Mich. Filed Apr. 7, 1964, Ser. No. 358,006 Claims. (Cl. 2-3) This invention relates to a safety helmet and more particularly, visor and ear protector attachments for a safety helmet.
Safety helmets such as of the type shown in the application of Zbikowski, Serial No. 229,573, filed October 10, 1962, now Patent No. 3,137,859, and in the patent to Zbikowski, No. 3,116,490, issued January 7, 1964-, are frequently used by police ofiicers who, at certain times, require some sort of visor to protect their eyes and the front of their faces and also some sort of ear protection. Since such helmets are frequently worn out of doors in the rain, it is desirable to detachably connect such visors and ear protective devices to the helmet in such a manner as to avoid rain leakage and yet to rigidly, although temporarily, secure such devices to the helmet.
Hence, it is an object of this invention to provide a visor construction for a safety helmet which rigidly attaches to the helmet shell and is easily removable therefrom, the connection being completely rain-tight.
In addition, it is an object of this invention to provide an ear protective means to be secured to a safety helmet, which means forms a rigid, rain-tight connection to the helmet and which can be quickly and easily removed when not needed.
These and other objects and advantages of this invention will become apparent upon reading the following description, of which the attached drawings form a part.
In these drawings:
FIG. 1 is an elevational view of a safety helmet with visor and ear protector means secured thereto.
FIG. 2 is a perspective view of the helmet, the visor means and ear protector separated.
FIG. 3 is an enlarged cross-sectional view of the front portion of the helmet with the visor secured thereto, and
FIG. 4 is a view similar to FIG. 3 but with the parts detached and separated.
FIG. 5 is a perspective view of the visor per se.
FIG. 6 is an elevational view, partly in crosssection, showing the ear protector connected to the helmet.
FIG. 7 is an enlarged, cross-section, fragmentary view taken in the direction of arrows 77 of FIG. 6, and
FIG. 8 is a fragmentary view taken in the direction of the arrows 88 of FIG. 6.
The safety helmet 10 is formed of an inverted, rigid, bowl-shaped shell 11 having a lower edge head 12 secured thereto. In addition, a suitable head supporting cradle or suspension and padding means (not illustrated) may be secured within the shell.
The shell is provided with three male snap fastener halves secured to the front portion thereof near its lower edge and in addition, with a pair of U-shaped strap members 14 secured by rivets 15 to the opposite sides of the shell. Connected to the lower end of one of the U-shaped strap members is an elongated strap 16 and connected to the opposite strap member is a buckle 17 secured thereto by a short strap section. Secured to each of the strap members are upper and lower female snap fastener halves 13.
The visor 20 is formed of a sheet of stiff plastic material and has an upper, integral edge strip 21 to which is adhesively secured a thick, resilient plastic ribbon 7.2, which may be formed of a suitable foamed plastic material, such as a waterproof polystyrene or the like (see FIG. 5). Formed in the strip and ribbon are openings 23 and 23a, which are aligned with the studs of the snap fastener halves 13.
To secure the visor to the shell, the openings 23 are aligned with and receive the studs 13 of the snap fastener halves and then a relatively stiff, but bendable plastic band 24, of substantially the same size as the visor strip 21, is arranged upon the outside surface of the visor strip and female snap fastener halves 25, secured to the band, are mated with the male snap fastener halves 13 of the shell. The ribbon 22 is sufficiently thick so as to be compressed considerably between the strip and the shell to thereby conform to the contours and irregularities of the shell and to form a tight, waterproof joint.
For policemen, the band 24 may be made in varying colors to denote rank or type of service, such as gold for an oflicer, silver for a lower ranking officer and black for patrolmen. The bands can be easily discarded and replaced, being inexpensive and easily removed.
To lighten the helmet, the shell is normally so formed as to not cover the ear portion of the wearers head. However, at various times, it is desirable for the police oflicer to have a rigid protective shield around the ears and the back of his neck. Hence, the ear protector 30, as shown in FIG. 1, is mounted upon the shell and may be removed when not needed.
The ear protector is formed of a fiat sheet of relatively thin, stiff but semi-flexible material which will fiex or bend only under considerable pressure, such as the application of about ten pounds by pressing against the sheet with the end of a human thumb, and which is characterized by returning to its initial shape upon release of the pressure. One material suitable for this purpose is that identified as Royalite 20, manufactured by United States Rubber Company, this being a semi-flexible, thermoplastic material of about 0.30" wall thickness.
The entire center portion of the sheet is depressed outwardly to form a dished portion 31 surrounded by an edge band portion 32 which remains in the plane of the sheet. Inserted in the dished portion is a thick, resilient padding strip formed of a resilient plastic material 33 which may be provided, long with the sheet, with openings 34 to transmit sound easily. The padded sheet is so located and is of a size to completely cover the ears and the portion of the wearers head around the back of the head and neck between the ears.
For removably fastening the ear protector to the shell, a vertical strip 36 is secured by rivets 37 to the forward edge band portion 32 at each forward edge of the sheet. These strips are formed of a stiff, slightly flexible plastic material. Their upper edges 38 and 39, respectively, are rearwardly bent and free of securement to the sheet and have male snap fastener halves 40 secured thereto.
In mounting the ear protector, its upper edge band portion is inserted within the helmet shell between the lower edge head 12 and the U-shaped strap members 14. The strap members are arranged between the protector sheet and the upper and lower ends of the vertical strips 36 with snap fastener halves 4t snapped into snap fastener halves 18.
A flexible tab 42 having a snap fastener 43 mounted thereon, is fastened to the rear of the protector at 31a for connection to a corresponding snap fastener half 44 secured to the rear of the shell. After the snap fasteners are connected, strap 16 and buckle 17 are inserted through the slots 41 so that they are arranged on the outside of the ear protector where they then can be fastened together around the chain of the wearer.
This invention may be further developed within the scope of the following claims. Accordingly, it is desired that the foregoing description be read as being merely illustrative of an operative embodiment of this invention and not in a strictly limited sense.
