15 Claims, 4 Drawing Figures US Pamm Sept. 23 1975 Sheet 2 of2 3 9%,547
BACKGROUND OF THE INVENTION There are known in the prior art headsets including a pair of earphone assemblies which are supported on a headband extending across the wearers head by means of flexible yokes at the ends of the headband the legs of which yokes carry inwardly extending pins which are adapted to be snapped into recesses formed in the earphone housings releasably to hold the earphone assemblies in position on the headband.
There are also known in the prior art flexible protective helmets with which earcup assemblies may be associated. One form of such a headgear structures is shown and described in US. Pat. No. 3,786,519, issued Ian. 22, I974. The headgear structure shown in the patent includes a flexible relatively close fitting helmet on which a plurality of bodies of impact resistent material are mounted. The helmet is provided with ear openings in which earcup assemblies comprising an integrally molded shell provided with a peripheral channel may be mounted. A salient feature of the headgear structure of the patent is the arrangement by virtue of which earcup assembly sealing means are brought into intimate contact with the wearers head so as to form a seal therewith when the helmet is donned by a wearer. This sealing effect takes place as the helmet is donned even though the chin strap of the helmet is not secured.
It is desirable that a headset earphone assembly of the type first mentioned above be able to be used with the flexible helmet shown in the patent mentioned above. At present there exists no means for attaching such an earcup assembly to the flexible helmet in a rapid, simple and expeditious manner.
l have invented a retainer for releasably securing a headset earphone assembly ofa type shown in the prior art to a flexible protectivehelmet. My retainer permits the headset earphone assembly to be secured to the flexible protective helmet in a rapid and expeditious manner. It is relatively simple and inexpensive to construct.
BRIEF SUMMARY OF THE INVENTION One object of my invention is to provide a retainer for releasably securing a headset earphone assembly of a type known in the prior art to a flexible protective helmet.
Another object of my invention is to provide a retainer for releasably securing a headset earphone assembly to a flexible protective helmet in a rapid and expeditious manner.
Another object of my invention is to provide a headset earphone assembly retainer which is simple in construction and which is inexpensive to manufacture.
Other and further objects of my invention will appear from the following description.
In general my invention contemplates the provision of a retainer for releasably securing a headset earphone assembly of the type having a pair of pin receiving recesses therein to a flexible helmet in which a relatively rigid frame is formed with an outwardly opening peripheral channel adapted releasably to receive a portion of the flexible helmet body surrounding an opening therein adjacent to the ear of a wearer. The frame forms a pair of housings which slidably receive plates for movement inwardly and outwardly of the frame opening which is so shaped that an earphone assembly placed in the frame is oriented with its pin receiving recesses aligned with inwardly directed projections on the plates so that the plates can be moved inwardly to engage the projections in the pin receiving recesses and then be releasably locked in position securely to retain the headset earphone assembly in place on the flexible protective helmet.

FIG. 2 is an end elevation with a part shown in section of the assembly of my retainer and one of the headset earphone assemblies of the type known in the prior art.
FIG. 3 is a fragmentary sectional view of the assembly illustrated in FIG. it taken along the line 33 of FIG. I and drawn on an enlarged scale.
FIG. 4 is a fragmentary sectional view of the assem bly of my retainer and a headset of the prior art taken along the line 4-4! of FIG. 3. 7
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings, a helmet assembly indicated generally by the reference character 10 may include a rigid outer shell 12 provided with a rudimentary visor l4 and an inner flexible protective helmet indicated generally by the reference character 16 of the type shown and described in the patent referred to hereinabove. The helmet 16 includes a fabric webbing 18 formed with a plurality of pockets adapted to receive bodies of impact resistant material, one body 20 of which is illustrated in FIG. I. Respective strips 22 of leather or the like secured along the lower front side portions of the helmet R6, are secured to a pair of fabric lengths 24 by any suitable releasable fasteners, such as snap-fastenersv The lengths 24 in turn are secured to the rigid shell 12 by any suitable means. Each of the strips 22 further carries a second snap-fastener element adapted to receive a complementary element carried by one end of a chin strap 26.
Preferably, the helmet 16 is provided with a nape strap 28 which permits the protective helmet to be drawn closely around the back of the wearers neck. A strip 30 of webbing or the like carries a fastener 32 adapted to be engaged with a fastener element 34 on the body of shell 12 to hold the back of the inner helmet assembly 16 to the rigid outer shell 12. Additional fastening means may be provided to secure the inner helmet 16 to the shell 112.
The inner helmet I6 is formed with respective ear openings 36, surrounded by beaded fabric portions 38.
The structure thus far described is more fully shown 7 and described in the patent referred to hereinabove.
The headset earphone assembly indicated generally by the reference character 40 includes an earcup 41 of relatively rigid synthetic resin forming a housing for an electrical component (not shown) such as an earphone. The earcup 41 carries a sealing assembly 49 comprising soft resilient material adapted to form a seal with the portion of the wearers head around his ear when the helmet I6 is donned so as to prevent extraneous sound from entering the cup. A valve member 42 carried by the earcup may be actuated to uncover an opening to permit the wearer to hear outside sound without removing the helmet.
The assembly includes a pair of pin receptacles indicated generally by the reference characters 44 and 46 positioned at generally oppositely disposed locations around the peripherery of the assembly 40. Each of the receptacles 44 and 46 includes a body 48 received in an opening 50 in a boss 51 on the earcup 41.
Each body 48 is provided with an aligning slot 52 and with a pin receiving recess 54 extending inwardly into the body from the slot 52 at a location generally in the center of the slot.
My retainer includes a frame 56 provided with a peripheral channel 58, having an inner wall 60 and an outer wall 62. I provide the frame 56 with a central opening 64, having a cross-sectional configuration which conforms to the shape of a portion of the outer surface of the assembly 40. Moreover, the outline configuration of the opening 64 is the same as that of the portion of the housing 48 adapted to be received thereby. A step or shoulder 65 in the opening 64 permits the assembly 40 to nest snugly within the opening 64 as illustrated in FIG. 2.
Frame 56 carries a pair of connector assemblies indicated generally by the respective reference character 66 and 68. Each of the connector assemblies includes a housing 70 formed by an outwardly offset portion of the outer wall 62 of the frame 56. Adjacent to each of the connectors 66 and 68, I provide a notch 72 forming a mouth leading from the edge of the opening 64 into the corresponding housing 70. As will be more fully described hereinbelow, when the assembly 40 is placed in the opening 64, each notch 72 receives the outwardly projecting portion of the corresponding body 48 of the receptacle.
A slot 74 in the top of the housing portion receives the shank 76 of a locking fastener, having a head 78. Shank 76 is threaded into a plate 80 disposed within the housing portion 70 for sliding movement inwardly and outwardly of the frame 56. 1 form each plate 80 with a projection or finger 82 extending inwardly of the frame 56.
In use of my retainer to mount a headset earphone assembly to a flexible helmet 16, I first mount respective frames 56 in the ear openings 36 of the helmet 16. This is accomplished by inserting the bead 38 into the channel 58 formed by the flanges or walls 60 and 62. Owing to the somewhat elliptical shape of the openings 36 and the corresponding shape of the frame 56, when this is done the fastener assembly 66 and 68 are generally at those locations at which they should be for proper positioning of the earcup assembly 40 on the helmet 16. It will be readily appreciated, of course, that this operation is performed in such a way that the fastener assembly 66 and 68 are outboard.
Next, in order to assemble one of the units 40 to a frame 56, it is applied to the opening 64 from the inside out. Owing to the corresponding shapes of the opening 64 and of the periphery of the earcup 41 unit 40, as this operation is performed the projecting portions of the bodies 48, will be aligned with the notches or mouths 72, so as to be received therein. It will be appreciated that before the operation the plates 80 are moved outboard to retract the pins or projections 82. Even in the retracted positions of the plate 80, the pins will project inwardly sufiiciently to enter into the guide slots 52 to insured that the pins are accurately aligned with the pin receiving recesses 54.
When the unit 40 is snugly in place in the opening 64 in the frame 56, pins 82 are aligned with recesses 54. In this relative position of the parts, the plates 80 are slid inwardly to cause the pins 82 to enter into the recesses 54. After the pins 82 have been moved into the recesses, each of the knobs 78 is turned to draw the corresponding plate unwardly into the recess formed by the housing 70 in the outer wall 62, so as securely to lock the parts in place. Then when the helmet is donned, owing to the helmet construction pointed out hereinabove, the sealing assembly 49 is brought closely into engagement with the surface of the wearers head about his ear.
It will be seen that l have accomplished the objects of my invention. l have provided a retainer for holding a headset earcup assembly of a type known in a prior art, to the body of a flexible protective helmet. My retainer accomplishes this result in a rapid and expeditious manner. It is relatively simple in construction and is easy to manufacture.
