Description




FIELD OF THE INVENTION




The present invention relates generally to headset assemblies and, more particularly, to a headset assembly having improved ergonomics.




BACKGROUND OF THE INVENTION




Headset assemblies are frequently used in a wide variety of applications and across a broad range of industries. For example, in the fast food industry, one or more employees at drive-through fast food restaurants typically wear a headset assembly to receive orders from patrons in the drive-through lane. Similarly, in the banking industry, tellers at banks having drive-through lanes may wear headset assemblies to communicate with customers. In the retail industry, headsets are commonly used by stockroom and other employees to communicate with one another within a large area, such as a department store or a warehouse.




A typical headset assembly includes a headband and an electronics housing. The headband typically consists of one single-rate leaf spring having only one unstressed width, but which is flexed to fit different sized heads. The electronics housing is typically attached to one end of the headband and usually includes an earphone speaker, a microphone boom, and the electronic circuitry necessary to operate the earphone and microphone. While being commonplace in today's society, conventional headsets are extremely uncomfortable and inconvenient to use.




SUMMARY OF THE INVENTION




Generally the present invention relates to a headset assembly having increased comfort and convenience of use. In accordance with one embodiment of the invention, a headset assembly is provided which includes a first headpiece pivotally coupled to a second flexible headpiece. The headset assembly further includes means for limiting the pivotal movement of the flexible headpiece with respect to the first headpiece. This allows the tension of the headset assembly to be suitable adjusted to the head size of the wearer.




In accordance with another embodiment of the invention, a headset assembly which includes a headband and an electronics housing pivotally coupled to the headpiece is provided. The pivotal coupling of the electronics housing with respect to the headband allows the electronics housing to be swung away from a user's ear and provides additional comfort to the user.




In accordance with yet another embodiment of the invention, there is provided a headset assembly having an electronics housing removably coupled to a headband. The electronics housing may, for example, be removably coupled between a headband and a cap of a user. The headset assembly may include a clip member for removably coupling the headband to the electronics housing.

DETAILED DESCRIPTION OF THE DRAWINGS




The present invention generally relates to headset assemblies having one or more ergonomic features which increase the comfort and convenience of the headset assembly for a user. An appreciation of various aspects and features of the invention will be gained through a discussion of an exemplary embodiment. While the exemplary embodiment illustrates a headset assembly which incorporates a number of these features, the present invention is not so limited. Headset assemblies including any one or combination of the features are intended to be covered by the present invention.




FIGS.


1


and


2


A-


2


B are perspective and cross-sectional views of an exemplary headset assembly in accordance with one embodiment of the invention. The headset assembly


100


includes a headband


110


and an electronics housing


120


. The electronics housing


120


generally encloses headset electronics, such as a circuit board, battery, etc. Mounted on the housing may, for example, be an earphone speaker


128


, a microphone boom


126


, and a touchpad


124


for operating the headset electronics. As should be appreciated, the earphone speaker


128


and microphone boom


126


are typically pivotally mounted to the housing


120


to facilitate comfortable positioning. Inwardly facing pads


130


formed, for example, from a polyethylene foam, may be mounted on the headset assembly


100


. As will be discussed more fully below, a battery


900


is provided on the housing


120


as well.




As noted above, the exemplary headset assembly


100


illustrates a number of features which enhance the convenience and comfort for a user. The exemplary headband


110


advantageously allows a user to adjust the unstressed width of the headband. The headband


110


generally includes two headpieces


112


and


114


, pivotally connected to one another, and a mechanism for limiting the pivotal movement of the headpieces so that the unstressed width of the headband


110


may be adjusted. At least one of the headpieces is relatively flexible so as to provide tension against the head of a user and thereby hold the headset in place.




In the illustrated embodiment, the two headpieces


112


and


114


include a relatively flexible headpiece


114


and a relatively rigid support headpiece


112


. The support headpiece


112


generally provides a supporting structure against which the flexible headpiece


114


may bend so as to provide the desired head tension to keep the headset in place. The headpieces


112


and


114


may be made of a number of different materials. For example, the flexible headpiece


114


may be formed from a flexible plastic while the support headpiece


112


may be formed from a relatively more rigid plastic material. One suitable plastic is Nylon, for example.




The flexible headpiece


114


is pivotally coupled to the support headpiece


112


near the end of the support headpiece


112


using a pin


117


. However the invention is not so limited. The pivotally connection may be formed in other manners. For example, the two headpieces


112


and


114


may be integrally formed with a relatively thin portion forming an integral hinge between the two headpieces.




In the exemplary embodiment, the mechanism for limiting the pivotal movement of the flexible headpiece


114


with respect to the support headpiece


112


includes a tab


162


slidably mounted on a portion


164


of the support headpiece


112


, as best shown in FIG.


2


B. In general, as the tab


162


is moved outwardly and inwardly, the unstressed width of the headband increases and decreases, respectively. In this manner, the unstressed width of the headband


110


may be appropriately adjusted to comfortably fit a user's head.




As best shown in

FIGS. 2A and 2B

, the tab


162


includes a surface


166


which engages the flexible headpiece


114


to both limit the pivotal movement of the flexible headpiece


114


as well as provide a structure against which the flexible headpiece


114


may flex or bend to provide head tension. The flexible headpiece


114


can be pivotally moved until it contacts the surface


166


at which point further movement of the flexible headpiece


114


results in the creation of a tensile force from the headpiece


114


.




As best illustrated in

FIG. 2B

, the exemplary tab


162


includes an upper portion


165


and a lower portion


167


, mounted to the extended portion


164


of the support headpiece


112


using a pin


169


. The tab


162


includes a set of groves


168




a


which mate with a set of groves


168


b on a surface of the headpiece portion


164


for setting the position of the tab


162


(and the width of the headband


100


). A leaf spring


169


may be provided to bias the grove sets


168




a


and


168




b


against one another. The leaf spring bias generally allows the tab to be readily repositioned yet prevents the tab from slipping on the headpiece portion


164


when pressure from the flexible headpiece is applied.




It should be appreciated that the tab


162


is provided by way of example only. A wide variety of other structures and mechanisms may be used to limit the pivotal movement of the flexible headpiece


114


. For example, a mechanism having a surface which is moved in a different plane than that of tab surface


166


may be used. Moreover, the present invention is not limited to three or any other fixed number of unstressed widths.




As illustrated in

FIGS. 3-5

, in the exemplary embodiment, the tab


162


is configured to allow pivotal movement of the flexible headpiece


114


to three different widths. More particularly,

FIG. 3

illustrates the tab


162


at an inner most position, which allows the flexible headpiece to pivotally move outward to an unstressed width W


1


. This provides the narrowest headband unstressed width and would be suitable for users having smaller head sizes.

FIG. 4

shows the tab


162


at an intermediate position, which allows the flexible headpiece


114


to pivotally move to an unstressed width W


2


. This provides an intermediate headband unstressed width and would be suitable for slightly larger head sizes. Finally,

FIG. 5

depicts tab


162


at an outermost position, which allows the flexible headpiece to be pivotally moved to an unstressed width W


3


. This provides the widest headband unstressed width W


3


for accommodating larger head sizes. The three unstressed widths W


1


, W


2


, and W


3


for the flexible headpiece


114


may be suitable selected to cover the broadest range of head sizes.




In operation, a user slides the tab


162


to a position which provides a desired unstressed headband width. Typically the unstressed width is slightly narrower than the user's head. The user then spreads the headband beyond its unstressed width by flexing the flexible headpiece


114


and slips the headband over his/her head. The tension provided by the stressed headband holds the headset in place.




The unstressed width of the above-described headband can advantageously be adjusted for various head sizes. Conventional headbands, as noted above, have only one unstressed width. With these conventional headbands, smaller heads are subject to less tension than larger heads. This often results in excessive tension on larger heads causing discomfort and too little tension on smaller heads making the headset prone to movement. The above headband alleviates these problems and allows users with different sized heads to receive more comparable head tension.




As best illustrated in FIGS.


2


A and


6


-


7


, the illustrated headset assembly


100


further provides an electronics housing which may be readily removed from the headband


110


and, for example, attached to a hat of a user. The hat may, for example, be a baseball cap, a visor, and so forth. In the illustrated embodiment, an exemplary clip member


140


, is provided to facilitate the interchangeability of the electronics housing


120


between a hat and a headband. While, the invention is not so limited, the clip member


140


may, for example, be made of a substantially rigid plastic material, such as Nylon.




The exemplary clip member


140


includes an upper portion


141


for attaching the clip member to the headband and hat, and a lower portion


148


to which the electronics housing


120


may be coupled. The clip member upper portion


141


includes two arms


142


and


144


which form a slot


146


therebetween. To attach the clip member


140


with the headband


110


, a portion


118


of the support headpiece


112


is slidably received by the slot


146


of the clip member


140


. The two arms


142


and


144


may be biased against one another with sufficient force to allow the clip member


140


to be slidably moved with respect to the support headpiece


112


while retaining the clip member


140


at a desired position with respect to the support headpiece


112


under normal conditions. The clip member arms may be formed separately or from one integral molding.




As best shown in

FIG. 2A

, the received portion


118


of the support headpiece


112


may be recessed with respect to an outer surface


119


of the support headpiece


112


. The recess may be sufficiently deep to allow the outer surfaces


143


and


149


of the clip member arms


142


and


144


to be relatively flush with the outer surface


119


of the support headpiece


112


. To secure the clip member


140


to the headband


110


, the support headpiece


112


may include a tab which engages an opening in the clip member


140


. The tab may be depressed for removing the clip member


140


from the headband


110


. In an alternate embodiment, a depressable button may be provided on the clip member to secure the clip member


140


to the headband


110


. The button may be depressed as the clip member


140


is slid downwardly against the headband to allow the clip member to be removed from the headband


110


.




The clip member upper portion


141


may also be used to attach the electronics housing to a hat. For example, the clip member


140


may attach to a hat by slidably receiving a hat between the clip member arms


142


and


144


. In an alternate embodiment, best illustrated in

FIGS. 7A-7D

, an adapter


700


is provided to attach the clip member


140


to a hat. The exemplary adapter


700


generally includes two legs


702


and


704


, which are typically biased toward one another. The leg


704


includes an upper flange


706


having a slot


710


(as best shown in

FIG. 7B

) and a lower flange


708


. To attach the adapter


700


to the clip member


140


, the slot


710


receives clip member arm


142


. The adapter


700


is slid down the arm


142


until the lower flange


708


clips beneath the pad


130


. A hat is attached to the adapter by sliding it between the adapter arms


702


and


704


. The cap adapter


700


may, for example, be formed from a stainless steel.




The above described clip member advantageously allows the electronics housing to be interchangeably connected to a headband and a hat. The exemplary clip member is illustrative only. The present invention is not so limited. For example, a clip member having only one leg which is received by a slot formed by the headband may be used to facilitate interchanging of an electronics housing. In this embodiment, a hat adapter could be employed to attach the clip member to a hat.




As illustrated in

FIG. 8

, the exemplary headset assembly


100


further includes an electronics housing


120


which may be pivoted away from a user's ear. Generally the electronic housing


120


is pivotally coupled to the headband


110


using a hinge


110


. The hinge


180


may, for example, include a variable friction pivot pin having a friction suitably selected to sufficiently hold electronic package


120


away from the user's ear while still allowing the electronics package


120


to be readily pivoted. This allows for the electronic package


120


to be positioned against the user's ear during periods of use and swung away from the user's ear during periods of nonuse or as desired to increase the comfort of the user.




In the exemplary embodiment, the electronics housing


120


is pivotally coupled with the headband


110


via the clip member


140


. In particular, the electronics housing


120


is pivotally coupled with the clip member


140


, for example, at the clip member extending portion


148


. The clip member


140


is in turn attached to the headband


110


, as discussed above. This allows the electronics housing


120


to be swung away from the user's ear when it is attached to a hat as well as a headband.




As best illustrated in

FIGS. 2 and 9

, the exemplary electronics housing


120


further includes a battery


900


. A portion of the battery


900


may lie outside of the electronics housing when attached, as best shown in FIG.


2


. For example, a portion of the battery


900


may occupy the space between the speaker


128


and the electronics housing


120


. By attaching the battery


900


to the electronics housing


120


, the need for wiring between one end of the headset


100


and the electronics housing


120


is eliminated. In addition, the housing


120


may be detached from the headband


110


and used for communication. By disposing the battery


900


between the housing


120


and the speaker


128


, otherwise unoccupied space is used and the width of the housing


120


may be reduced while still providing sufficient power for the electronics in the housing


120


.




The battery


900


may be attached to the electronics housing


120


in a number of different manners. In the exemplary embodiment, the battery


900


is slidably received by a slot


902


in the electronics housing


120


, as best illustrated in FIG.


9


. For securing the battery


900


in the slot


902


, the received portion of the battery


900


and the slot


902


may have shapes or structural features which mate together to retain the battery


900


. For example, the slot


902


may include flanges


904


, on each side of the slot


902


, which mate with corresponding recesses


906


on the battery


900


. In the exemplary embodiment, a portion of a lower region of the battery


900


extends beyond an upper region of the battery


900


to form the battery recesses


906


. A latch


908


may further be provided to secure the battery


900


in the axial direction of the slot


902


. The latch


908


may, for example, be a spring loaded latch which is disposed upward while the battery


900


is inserted and which moves downward to engage a notch


910


in the battery


900


when the battery is fully inserted. To remove the battery


900


, the latch


908


may be biased upwardly.
