Description
1~ 1321008 IMPROVEMENTS RELATING TO TEL~PHONE HANDS~TS
BACKGROUND OF THE INVENTION
_ The present invention relates to the provision of a telephone handset of ergonomic design.
The functionality of the modern telephone is far greater than the original devices and the telephone of today is even more refined than those of a just a few years ago.
The past decade has seen a major advance in design technology, creating telephones which are easier to use and capable of a multiplicity of functions. Included among these innovations are: a hand free function which allows conversations through the use of an internal loudpeaker, on-hook dialing, abbreviated dialing, memory functions, ~ -minor calculating/computing functions, automatic trans~er of calls, LED readouts. All these are embodiments which rely in part on the inbuilt mechanics of the telephone unit itself, a modern internal technology which is also augmented by the capabilities of the PABX - the Private Automatic Branch Exchange.
In stark contrast to functionality, and considering that the design of the telephone has undergone dramatic cosmetic modifications, the visual and ergonomic theory of the handset has remained basically static and its inherent theoretical approach unaltered since circa 1893 when the ear and mouth pieces were first joined into one unit.
Although the telephone, given that it normally consists of a base control unit and accompanying handset, has been modernised in form, it remains basically identical in intent as when originally conceived. Apart from more modern designs the only palpable advance in exterior appear-ance has been the introduction of a push button keypad.
This has now replaced the rotary dialler, though even this embodiment is a relatively recent innovation considering the long history of the telephone. Until recently, the design of the telephone handset has followed the constraints which were originally placed upon its form, by the technology which existed at the time it was first manufactured.
~3210~8 Decades ago the microphone and speaker units were bulky and thus the handset containing both was equally cumbersome. Today, both microphone and speaker technologies have drastically improved and each device is now minute in comparison to its predecessor which has led to smaller, more compact handsets in flagrant disregard for the ergonomic function of the unit. Emphasis has been placed on miniatur-ising the handset, of forming it about the face of a user or moulding a more comfortable grip instead of addressing the ergonomic deficiencies inherent from the earliest manifest-ation of the handpiece. There is a basic, hitherto unseen, theoretical flaw in all known embodiments of the telephone handset. There is little or no evidence that telephone designers have considered the overall ergonomics of the product and appear to have made the mistake of concentrating on the hand and face whilst ignoring the total interaction of head, hand, wrist, arm and shoulder.
Therefore any claimed ergonimic capability has been partial at best. Such ergonomic oversights have resulted in the continued production of telephone handsets whose basic design tenet remains theoretically flawed.
Unfortunately, such technical progress has created handset/base products which are conceived by those of a technical or engineering background - scientific expertise which is then transformed into products which seemingly ignore the "human factor ergonomics" intrinsic in this field of communication, or by designers with no "long term"
knowledge of how the product is actually used.
With regard to the human interaction factor, many obvious examples exist regarding the lack of environmental consideration; thorough examination of design philosophy or ergonomic practicality: dialling mechanisms which are far too small for ease of use, handsets which are so compact as to be uncomfortable, facilities too varied and too complicated for most to bother with, limited choice of colour and no supplied alternatives to personalise product, use by the handicapped mostly ignored, phone boxes which are noisy.
The major function of the telephone is to perform a clear means of communication, however the substandard performance of the product in noisy environments as now exists, is patently inadequate. It is also a major objective that the telephone is comfortable to use even in long telephone conversations.
In my earlier international patent application No. W087/07798 published in 1987 I had disclosed an ergonomic .
telephone having a handset inter alia, having a speaker portion shaped or constructed to rest against the cheek bone or skull of the user and having a handle portion located to minimise muscular stress in the body of the handset user.
SUMMARY OF THE INVENTION
It is a principle objective to provide a telephone handset designed for use in a variety of positions allowing natural positioning of the hand, wrist, upper arm and shoulder in comfort yet maximising the performance of the handset.
In use, as specifically designed, the conventional handset requires the user to position the grip portion, and thus the hand, between his/her ear and mouth which raises the arm up and away from the body whilst also creating a lateral twisting motion of the wrist. Complex anatomical interactions are involved in performing the seemingly simple task of holding a telephone handset. The shoulder, upper and lower arm, the wrist and the hand must all be engaged then remain stressed to hold the conventional telephone in the position the handset was designed to retain to maintain and maximise efficiency of useage of the handset.
Thus the present invention sets out to provide a design which minimises the energy required in lifting, holding and replacing the handset, while reducing the anatomical stress needed to retain the optimum technical po6ition. Obvious advantages stem from improved design particularly in long conversations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
In each of the series of the figures the mouth piece and handle piece 10 and 11 are indicated by common reference numerals and can be considered to have a similar construction. The different embodiments relate in most instances to the provision of a flexing or pivotal ear piece in accordance with the inventive concept.
With reference to figures 1 and 2, the handle 10 has mounted at one end a microphone 11 and at its other end an ear piece 15 wh$ch is resiliently or flexibly mounted at 16 to the hand portion 10.
The ear piece 15 has a face engaging portion 12 which may be flexible in the area at or near its end to 8moothly engage the users face adjacent his ear.
The ear piece 15 incorporates a speaker 14 and a cap member 13 which may be replaceable and is preferably of soft foam material. The cap members 13 may be easily replaceable and if desired may be produced in various colours.
132~0~
In use the hand piece engages the users face in the vicinity of the ear on the cheek bone and the ear piece may flex about point 16 in order that the surface of the cap easily aligns with the users ear in use.
With reference to figures 3 and 4, the hand piece may be of conventional construction including hand portion 10, mouth piece 11, with an ear piece 15a.
On the ear piece l5a, a cap member 17 is slidably mounted on the ear piece 15 and attached to the handle piece by a flexible member 18. The arrangement is such that when the hand piece is in use the cap member 17 engages with the users ear and flexes about the connection member 18 to align itself with the users ear.
With reference to figures 5 and 6, these figures show different embodiments of cap members 19 and 21. With reference to figure 5 the cap member 19 is mounted on ear piece 24 in slidable relationship under the influence of a bias spring 20 such that the cap member moves relative to the ear piece 24 under the pressure of application to a users ear to substantially align itself with the users ear in a comfortable position.
With reference to figure 6 the cap member 21 is slidably mounted on an ear piece 23 and incorportes a concertina portion 22 allowing flexibility of movement of the cap member 21 to align itself with the users ear in use.
With reference to figures 7 and 8 the hand piece 10 and microphone portion ll incorporate a movable microphone mounted upon arm 25 pivotally connected to one end of the handle portion 10 at 26. The ear piece 15 is otherwise manufactured in similar manner to that shown in figure 1 incorporating a cheek bone rest portion 12 and cap member 14.
The arrangement is such that the ear piece and microphone member can pivot about pivot point 26 so that the microphone remains adjacent the users mouth whilst the cap member is aligned with the users ear.
In other words the microphone or ear piece remains aligned with the ear independantly of the movement or disposition of the handle portion.
With reference to Figures 9, 9A and 9B, there is shown a handset 30 including a microphone portion 31, a pivot connection 32 and speaker or ear piece portion 33.
Figures 9A and 9B show in more detail two embodiments of the pivotal connection between the ear piece 33 and the body of the handset 30.
With reference to Figure 9A, the pivotal connection 32 includes a shaft 34 mounted on shoulders 36 connected to the speaker portion 33.
The speaker portion 33 includes a further shaft 35 extending perpendicularly to shaft 34. This enables the speaker portion to rotate about two pivot points to allow universal movement of the ear piece relative to the body 30.
With reference to Figure 9B, the ear piece 33 is mounted upon a shaft 37 mounted in slots 39 in the body of the handpiece.
The shaft is biased by a compression spring 38 to a stable position in the slots 39 but is sufficiently pliable to allow movement of the ear piece 33 to align itself substantially with the line of a user's ear in use.
Referring to Figure 10, there is shown a handpiece 40 having a housing slot 41 in which an ear piece and microphone 42,43 are mounted in pivotal fashion about a pivot point 44 in the housing.
The ear piece 42 includes a soft pad 43 for contact with the ear of a user. The pivot point 44 allows pivotal movement of the ear piece and pad 42,43 and concurrently wlth any movement of the ear piece the microphone portion 41 and associated arm 41a as shown in phantom outline also is moved to maintain the position of the micrphone relative to the mouth of the user whilst aligning the pad on the piece with the ear of the user.
The microphone portion 41, ear piece 42 and arm 41a are removable from the body 40 and can be utilised as a separate headphone set as shown in Figure 11~.
