Description

IMPROVED HEAD-SET TELEPHONE DEVICE AND METHOD The invention generally relates to telephone devices and methods, and in particular, the invention relates to head set type telephone devices and methods there for.
In the past, various telephone devices were developed for the ease and use of the subscriber.
Generally speaking, many of these various telephone devices were developed for use with electrical type telephone cords connected to a hand-held unit that a person used for both speaking and listening purposes.
In recent times remote type telephone devices were developed which did not use electrical type telephone cords connected to the hand-held unit. These remote type (cordless) telephone devices were developed for both conventional telephone systems and for cellular telephone systems.
One problem with these prior art telephone devices is that one hand of the user is fully occupied with holding the hand-held unit for speaking and listening purposes.
Accordingly, there was a need to provide head-set type telephone devices that were reliable and capable of use for either conventional or remote telephone systems.
Therefore, it is an object of this invention to provide improved head-set type telephone devices and methods therefor.
It is a further object of this invention to provide improved head-set type telephone devices and methods therefore which can be used with either remote (cordless) or cord type telephone systems.
It is a still further object of this invention to provide improved head-set type telephone devices and methods therefor which have means associated therewith to insure more reliable gripping action on a person's head.
It is still another object of this invention to provide improved head-set type telephone devices and methods which have unique mechanical means associated therewith to facilitate both coupling to telephone cradles and provide better gripping action on a person's head.
According to the present invention, various telephone devices are provided. One telephone device comprises a cradle and a headset. The headset has a center housing with a chamber. This housing has first and second ear speakers and first and second retractable means with respective outer ends fixedly connected respectively to the first and second speakers and with respective inner ends slidable connected to the center housing for disposition in the chamber when retracted.
According to another embodiment of the present invention, an improved headset telephone device is provided. The headset has a two-piece housing that resembles a conventional telephone handset when the headset is retracted, with one piece containing the ear speaker and the opposite piece containing the microphone. The headset may be used in its retracted state as a standard hand-held telephone handset. The device is extended by mechanically (not electrically) separating the two pieces of the headset housing, which separation causes retractable means to extend from each piece of the housing to form a headset.
According to a third embodiment of the invention, an additional ear speaker is provided on the piece of the housing where the microphone is located. The ear speaker on the piece where the microphone is located always functions as a speaker. The ear speaker on the other piece of the housing functions as a speaker when the headset is retracted. Extending the headset by separating the two pieces of the housing of the headset causes connections to the ear speaker farthest from the microphone to be broken thereby causing this ear speaker to not function as a speaker when the headset is used in its extended position.
The foregoing and other objects, features and advantages will be apparent from the following description of the preferred embodiment of the invention as illustrated in the accompanying drawings.

As shown in Figures 1,2,3,4,5, and 6, a first embodiment of a telephone device headset 11 in accordance with this invention is provided. Headset 11 (Figure 1) may be connected with a cord to a base telephone unit, or may be a remote or cordless type headset for use by a subscriber away from the base telephone unit. The headset 11 is shown in its retracted position in Figure 1. The base telephone unit and the electronic components for the headset 11 are not shown because they are known.
As shown in Figure 1, headset 11 is a headset which can be used in a home or office or for cellular type applications or systems. Headset 11 has a two-piece housing comprising housing pieces 13 and 14.
Housing piece 14 contains an ear speaker (not shown) beneath the ear piece 17, which is used to listen to the telephone. Housing piece 13 contains a microphone (not shown) located under the mouthpiece 15 in the housing 13, and a voice tube 16. Figure 1 shows the voice tube 16 in a movable, retractable configuration, but voice tube 16 may have other configurations within the scope of the present invention. Voice tube 16 may use the microphone located under the mouthpiece 15, or may have a separate microphone which may be located within the housing 13 or at any point along the length of the voice tube 16. In addition, voice tube 16 may also be used as an antenna for cordless phone applications.
Figure 3 shows the extension of the two housing pieces 13 and 14 to form a headset which can be worn on a person's head. With the headset 11 in its retracted position 3A, the user places one hand on the housing piece 13, the other hand on housing piece 14, and pulls the two housing pieces 13 and 14 apart, which separation reveals the retractable means which connect the two housing pieces 13 and 14. Once extended to position 3B, the headset may be placed on the user's head for hand-free use of the headset, as shown in Figure 2.
Figure 4 is a cross-sectional view of Figure 3 taken along line 4-4 and shows the outline of the housing and the retractable means 18 and 19.
Retractable means 18 and 19 are comprised of a center enclosure which houses stainless steel bars of substantially rectangular cross-section, which have an inwardly-biased spring action to provide reliable gripping of the headset 11 (Figure 1) to the head of the user 12 (Figure 2). These bars slide into and out of the center enclosure of the retractable means, providing the extending and retracting action. These stainless steel bars may also be used as antennae for cordless or cellular phone applications.
Figure 5 shows the retractable means 18 and 19 of Figure 4 in more detail. Retractable means 18 includes a bar portion 20 and a track 21. Retractable means 19 is of similar construction, and includes a bar portion 22 and a track 23. As can be seen from Figure 5, the two tracks 21 and 23 are overlapping, allowing the bars 20 and 22 to overlap when the headset 11 is in its retracted position, as shown in Figure 1. These two overlapping tracks 21 and 23 form the central enclosure portion 26 of the retractable means, as shown in Figure 2. The bars 20 and 22 have respective stops 24 and 25 to prevent the bars 20 and 22 from completely disengaging the tracks 21 and 23 of the central enclosure portion 26 of the retractable means 18 and 19.
The headset 11 has features to assure a comfortable fit and reliable gripping action on the user's head. Figure 6 shows in more detail how the housing piece 14 pivots on the bar portion 20 of the retractable means 18 shown in Figure 4. The point 27 where the bar 20 attaches to the housing 14 is a movable pivot, which allows the surface of the ear piece 17 to move as shown to accommodate different shapes of the heads of users. Although not shown, tongue 22 attaches to housing 13 in the same manner.
The inwardly biasing action of the retractable means 18 and 19 causes both housing pieces 13 and 14 to pivot to a position flat against the user's ears, giving greater comfort to the user and a more sure grip on the head of the user.
As shown in Figures 7,8,9, and 10, a second embodiment of the present invention is provided. All features of this second embodiment that correspond to like features in the first embodiment are numbered with the same numerals used in the description of the first embodiment with the addition of the suffix "A". In addition, the features and operation of this second embodiment of the invention are similar to those detailed in the explanation of the first embodiment, with the exceptions described hereafter.
Housing piece 13A, in addition to the microphone and voice tube explained in the first embodiment, also contains an ear speaker 29 located under the mouthpiece 15A in housing 13A. This ear speaker 29 is connected to the ear speaker 28 in housing 14A by way of wires 31, which pass through connectors 32 where the two housings 13A and 14A meet (see Figure 7).
Connectors 32 have pin portions 33 and socket portions 34, as shown in Figure 10. By extending the headset, pin portions 33 are separated from socket portions 34 of connectors 32, thereby breaking the connection to the ear speaker 28 located in housing 14A, making ear speaker 28 inoperable while the headset lIA is in an extended position.
Figure 8 shows a side view of the headset llA shown in Figure 7 in its retracted position. Once the headset llA is extended as shown in Figure 9, the headset 11A may be placed on the user's head for hand-free use of the headset llA, as shown in Figure 2.
As shown in Figures lOb, 11 and 12 another embodiment of a telephone device lOB in accordance with this invention is provided.
