United States Patent 3,422,459 PROTECTIVE HEAD COVERING Charles E. Bowers, Jr., Newtown Square, Pa., assignor to The Fibre-Metal Products Company, Chester, Pa., a corporation of Pennsylvania Filed Dec. 9, 1966, Ser. No. 600,571 US. Cl. 2-3 Int. '01. A421: 3/00; A42c /04 2 Claims ABSTRACT OF THE DISCLOSURE This invention relates generally to protective head coverings.
' As is well known to those versed in the art, protective head coverings may conventionally employ a hard outer shell and a flexible, yieldable inner liner seated on the wearers head and suspending the outer shell in spaced relation with respect to the wearers head. Protection from hazards of flying objects and the like requires that the liner 'be yieldable under impact against the shell for absorbing or cushioning the impact, while comfort to the wearer demands that the head covering afford adequate free flow of air and ventilation. In practice, liners of protective head coverings have heretofore been formed of yieldably distensible sheet material, such as plastic, for absorbing the shock of impact; and further, such liners have substantially completely covered the wearers head to distribute the force of impact with minimum unit pressure. The requisite liner area provided to minimize unit pressure has resulted in decreased liner yieldability and discomfort to the wearer by failure of ventilation to the Wearers head.
Accordingly, it is an important object of the present invention to provide a unique protective-head-covering construction wherein substantial area of liner adequately minimizes unit pressure under impact, while yieldability is increased and comfort is enhanced by more effective ventilation.
It is a further object of the present invention to provide a protective-head-covering structure wherein the shell is more effectively reinforced and rigidified about its peripheral edge, while being provided with effective drainage as of rain water, and the like.
It is still another object of the present invention to provide a protective-head-covering structure having the advantageous characteristics mentioned in the preceding paragraphs, wherein a highly improved detachable connection is afforded between the liner and shell.
It is still a further object of the present invention to provide a protective head covering of the type described which is extremely simple in construction, durable and reliable throughout a long useful life, and which can be economically mass-produced for sale at a reasonable price.
Other objects of the present invention will become apparent upon reading the following specification and referring to the accompanying drawings, which form a material part of this disclosure.
The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts, which will be exemplified in the construction hereinafter described, and of which the scope will be indicated by the appended claims.

FIGURE 11 is a partial elevational view taken generally along the line 1111 of FIGURE 10; and
FIGURE 12 is a partial sectional elevational view taken generally along the line 1212 of FIGURE 10.
Referring now more particularly to the drawings, and specifically to FIGURES 1 and 2 thereof, a protective 'head covering is there generally designated 20, and includes a relatively stiff or hard outer shell 21, and a relatively flexible inner liner 22 in spaced conforming relatiOn within the shell.
More particularly, the shell 21 may be formed in any suitable manner, say molded of plastic, including a concave, downwardly opening dome 25, which may be formed at its lower forward edge with a cap peak 26, if desired. Along the lower rear and side edges of the shell 21 there may extend a trough 27, facing upwardly and opening at its forward ends on opposite sides of the shell. The trough 27 may be defined by an outstanding ledge 28 extending along the lower rear and side edges of the shell, and an upstanding wall 29 along the ledge, spaced outward from the shell. In addition to the rigidifying function of the trough 27, it serves to receive and drain rain water, and the like, in a manner most comfortable to the wearer.
In addition the shell 21 is provided along its lower rear edge, and the adjacent portions of its side edges with a pair of generally parallel, spaced, depending reinforcement members or ribs 30 and 31. The reinforcement member or rib 30 is innermost, and may constitute a depending extension of the shell 25, while the outer reinforcement member or rib 31 may constitute a depending extension of the trough wall 29. By the reinforcement members 30 and 31, additional rigidity and strength is afforded the lower rear and side edge portions of the shell.
Interiorly of the downwardly facing, concave shell 25, at spaced locations about, and adjacent to the lower shell edge, there are provided a plurality of sockets 34. The sockets 34 may advantageously be formed integral with the shell, as smooth enlargements on the internal surface thereof, each having an internal cavity 35 opening downwardly from the respective socket, being bounded on its outer side by the adjacent wall portion of shell 21, and on its inner side by an inner wall 36 of the respective socket 34. The cavity 35 of each socket 34 opens downwardly from the socket; and further, each socket inner wall 36 is formed with a generally vertically extending thru slot 37, also opening downwardly. That is, the slot 37 of each socket 34 opens through its respective inner socket wall 36, affording lateral communication between the cavity 35 of the respective socket 34 and the interior of the shell 21. As best seen in FIGURES 6 and 7, each socekt slot 37 is provided intermediate its upper and lower ends with a reduced region, as defined between a pair of detents or projections 38, for a purpose appearing presently.
The liner 22 is advantageously fabricated of yieldable flexible material, and may be integrally molded of plastic, or otherwise formed of suitable material. The liner 22 may be symmetrical about its longitudinal centerline, and substantially flat in an unflexed condition, so that the partial plan view of FIGURE 9 is complete in detail. It will there be seen that the liner 22 includes a central portion 40, which may have a relatively large central opening 41. Formed in the central liner portion 40 may be a series of radially spaced, annular arrays of thru apertures, say the arrays of apertures 42, 43, 44, 45, 46, 47, 48 and 49. It will be observed that the multiple apertures cover substantially the entire area of the liner 22, so that the liner is substantially reticulate or of openwork configuration.
At circumferentially spaced locations about the liner 22 there are provided a plurality of liner extensions 51, 52, 53, 54, 55 and 56. These extensions may be formed integral with the liner, if desired. Certain of the extensions, say extensions 51, 53, 54 and 56 may be provided on one side with bosses, as at 57, 58, 59 and 60. The boss 60 is best seen in FIGURES -12 as including a projection on one face of liner extension 60, and an enlargement or head 61 on the projection spaced from the liner extension. As best seen in FIGURES 11 and 12, the boss 60 may be of an elongate configuration, essentially similar to that of slot 37, having a reduced medial portion 62, similar to the slot portion between detents 38. Further, the head 61 of boss 60 is configured for conforming engagement in a cavity 35 of socket 34. The several bosses 57, 58 and 59 may be substantially identical to the boss 60.
The remaining liner extensions 52 and 55 may each be provided with a series of spaced apertures, as at 65 and 66, each such series being arranged radially of the liner 22.
In addition, the liner 22 may be formed with a plurality of radially inwardly extending cutouts to facilitate flexure of the liner to its concave configuration of FIG- URES 1 and 2. For example, a cutout 67 may extend radially inwardly from the forward end of liner 22, while a cutout 68 may extend radially inwardly from the rearward end of the liner, both the forward and rearward cutouts terminating short of the central aperture 41. Similarly, a pair of side cutouts 69 may extend radially inwardly from opposite sides of the liner, also terminating short of the central liner aperture.
By reason of the radial cutouts 67, 68 and 69, as well as the liner apertures 41-49, the liner may be readily flexed to assume a concave configuration and disposed in generally conformably spaced relation within the shell 21. In this condition, the several extensions 51, 53, 54 and 56 are arranged adjacent to respective sockets 34 of the shell, and the bosses 57, 58, 59 and 60 are engaged upward into the socket slots 37, extending therethrough, with the boss heads conformably received in the respective adjacent socket cavities 35. This condition is best seen in FIGURES 2 and 3. Also, it will be apparent that the configuration of the bosses 57, 58, 59 and 60, as represented in FIGURES 1012, is such as to snapengage into the respective receiving slots 37, as by snap engagement of the slot detents 38 into the reduced boss region 62. This prevents inadvertent removal of bosses from the receiving slots, while permitting deliberate removal therefrom. Thus, the bosses 576tl serve as means for connecting the liner 22 to the shell 21 in a detachable manner.
Extending circumferentially about the lower region of the concavely configured liner 22, interiorly thereof, is a headband '72. The headband may include a flexible strip 73 bent upon itseil with its ends in overlapping engagement, and carrying along one edge a relatively soft headengaging member 74 folded to lie along the interior of the strip 73. The strip 73 is connected to the several liner extensions 52 and 55, as by a headed button or shank 75. That is, a headed button or shank 75 extends through the strip 73 and is selectively passed through one of the apertures 65, 66 to detachably connect the headband to the liner 22. As will be apparent, the headband is vertically adjustable relative to the liner by insertion of the button 75 through a selected upper or lower extension hole 65, 66. If desired, the headband strip 73 may be circumferentially adjustable to accommodate different head sizes, in the conventional manner.
It will now be understood that the liner 22 provides a suspension structure for the shell 21, with the liner seating on a wearers head serving to suspend the shell in spaced relation over the wearers head. By reason of the multitude of apertures or perforations through the liner 22, the liner is afforded a flexibility for smooth conforming engagement with the wearers head, as well as a yieldability for absorbing impact or shock, and enhanced ventilating characteristics for comfort. As the multitude of apertures 41-49 are located substantially com letely over the entire area of the liner 22, it will be appreciated that there is an effectively even distribution of unit pressure against the wearers head in the event of impact.
From the foregoing, it is seen that the present invention provides a protective head covering which fully accomplishes its intended objects and is well adapted to meet practical conditions of manufacture and use.
Although the present invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it is understood that certain changes and modifications may be made within the spirit of the invention and scope of the appended claims.
