Abstract

PURPOSE: To improve the wearing facility of a communication set by using a U-shaped member of the set that has a loop at its neck side, the bending parts at its chin side and the receivers at its both sides respectively and also making the receiver holders move toward an ear strap. CONSTITUTION: This communication set consists of a U-shaped member 6 which as a loop at its chin side, the holders 1a and 1b which are fixed at both ends of the member 6 and have receivers 2a and 2b, and a microphone 8. Then the webs 4 extend in a temporal bone range and form the 1st parts of the member 6 for both receivers 2a and 2b respectively. That is, the webs 4 first extend in parallel to the planes of ear side faces of the receivers 2a and 2b. Then the parts of the webs 4 which are bent at the chin side of the member 6 are symmetrically tapered toward the lower side and end in an arc shape. In such a constitution, the wearing facility of the communication set is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The invention relates to a set for communication, which is provided with a U-shaped member having at least one receiver and is provided with or without a microphone. Concerning things that have no form.

Conventional technology For use in certain communication ranges, for example in the case of conferences or lectures with simultaneous interpretation, or in the case of relatively short communication times or in the case of communication with many interruptions, special performance is required. Such a handset set must be extremely easy to use, even for users who are usually not very familiar with such aids.

Whether a handset set is suitable for the use case described above depends primarily on whether this handset set is extremely easy to operate and whether this handset set is easy to put on. Depends on.

The handset set known, for example from DE-A-3512347, consists of a headband and two earshell-shaped capsules.

What is generally true for a handset set constructed in this way is that the headband itself is already not very comfortable to wear. Observation has shown how difficult it is for wearers of such handset sets to properly wear the headband. The cause of this discomfort, as it turns out, is based on various human instincts, and therefore the wearer of such a handset set should
The headband can be rotated downward and worn around the neck. When worn in this manner, ie, when the original function of the headband is disabled, the functionality of the entire handset set is also significantly impaired. That is, the holding pressure of the handset set no longer acts on the wearer's head via the headband, but now via the ear capsule and onto the external ear shell, resulting in pressure on this sensitive organ. This makes the wearer want to quickly remove the handset.

These mechanical effects can also be recognized, for example, if the handset set is applied to one ear by hand via only one capsule.

However, in any case, if such a set has a transmitting function, the transmitting function cannot be used unless the set is worn as specified.

Known handset sets constructed to avoid the above-mentioned drawbacks include a U-shaped receiver suspended downwardly on the cervical side.
It is separated from the letter-shaped member and two earplugs. In this case U
The glyph is manufactured from a light material and its preload itself is small. This is because this preload acts fully as specified on the earplug, which exerts a compressive force on the ear canal.

Despite the regularity and precision with which these earplugs are covered with foam material, it is impossible to avoid compression and heat build-up over time; The discomfort caused by the build-up of such components impairs the wearing comfort of known handset sets of this type.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to improve a set/set of the type mentioned at the outset in order to improve its wearing comfort and make it as good as possible, while also making it easy to put on the set. The goal is to provide such a means.

Means for Solving the Problem In order to solve this problem, the present invention provides a configuration in which the U-shaped member is looped on the side of the neck and bent on the side of the chin, so that both open ends of the U-shaped member are looped on the side of the neck and bent on the side of the chin. Part web is 1 each
The ear strap has two receivers, the retainer of which transitions into an ear strap terminating in a free end.

Effects of the Invention The major advantages of the present invention include the following. That is, with the configuration of the present invention, the set can be easily worn, and moreover, the set can always be positioned at an appropriate position with respect to its receiving function and, in some cases, its transmitting function.

Furthermore, this set of receivers does not create a compressive point on the wearer's ear shell, despite the necessary preload by the U-shaped member.

This is because this force is introduced into the ear root or root bone or the anterior ear process via the ear strap integrated into the receiver holder and, in some cases, the cushion integrated therein. The receiver itself is completely unloaded.

In order to minimize the required preload, the U-shaped members of the set, in the installed or expanded state, describe a so-called "tunnel-shaped shape", which is characterized by: ing. That is,
Extending the temporal bone and on the receiver side U lt
[The web forming the first part of the material initially extends parallel to the plane of the ear side of the receiver, and the bent part on the jaw side of the U-shaped member then extends symmetrically downwards. It tapers, then transitions into an arc and ends.

This optimal spread mentioned above is set such that the spacing between the temporal sides of the receiver is 150 mm, which is based on international statistical data and corresponds to the average head size. It is equivalent. Even if the shape of the head is extremely large, if the contour of the U-shaped member is selected in this way,
Its preload in the fitted state increases only minimally, which is due to the optimal course of the shape of the U-shaped part and its soft spring properties from deflection.

Another advantage of the invention is that the set according to the invention can be worn like eyeglasses, regardless of whether the wearer already wears eyeglasses. As a result,
This set is extremely easy to handle, even if the wearer is inexperienced. This familiar donning operation is made even easier by the entry edge of the ear strap providing introductory comfort.

Further advantages of the present invention include the following. The U-shaped part of the set according to the invention has a forwardly directed bend on the jaw side, by means of which
The U-shaped element no longer gets in the way in the neck area and does not create friction points there.

Example The invention will now be described in detail with reference to the drawings.

FIG. 1 generally shows a set with transmitting and receiving functions, that is, a handset set. The handset set comprises a U-shaped member 6 forming a loop on the chin side, a holder 1a, lb fixed to the end of this U-shaped member 6 and provided with a receiver 2a, 2b each, a microphone 8, and a microphone 8. It is empty. The U-shaped member 6 advantageously consists of a thin metal plate surrounded by a soft material. The material surrounding this metal plate also surrounds a cable (not shown) connected to the receiver.

At its ends, the U-shaped elements 6 each have a thin web 4, which serves as a rail for a guide 5 integrated into the holders 1a, 1b. This guide 5 is constructed in such a way that the holding body 1a+lb can be slid along the thin web 4 by hand over a defined length distance over a defined stictive friction. The necessary static friction can be produced, for example, by flat springs that are integrated into the guide 5 and act on the sides of the thin web 4. This slidability influences the length of the U-shaped member 6 so that by this measure the U-shaped member 6
As long as it does not hit the wearer's chin, it can be adapted to a variety of different facial sizes.

In the area of the lower jaw, the U-shaped element 6 is bent forward, that is, away from the neck;
This bent portion has a sufficiently large distance from the wearer's neck.

In the area of this bend, a hinge point 9 is provided, from one of which branches a microphone strap 7 with a microphone formed at its end. This hinge-like arrangement allows an optimal and unhindered positioning of the microphone 8 in front of the lips. The holders 1a, lb each have a receiver 2a, 2b on the side facing the ear, both receivers being located at the hole in the ear shell when the handset set is being worn. The special construction of the ear straps 3a, 3b is shown in FIG.

A cable 10 extends from the U-shaped element 6 and terminates after a defined length in a plug 11, which is a connection to a control device, not shown. A soft cushion 1 is attached to the ear side portion of the holder 1aib, which is arranged in a half-moon shape around the receivers 2a and 2b.
6a, and this cushion is approximately the receiver 2a.
, 2b. This, together with the effects described below, provides optimum comfort when wearing the handset set.

When the handset set is installed, the U-shaped member 6 occupies a "tunnel-shaped shape", which tunnel-shaped shape is located at the hinge point 9.
A thin web 4 extending to the receiver 2a
, 2b is characterized by extending parallel to the plane of the receiving surface on the ear side. of the U-shaped member 6,
The locking portion bent toward the chin from the hinge point tapers inwardly and symmetrically, terminating in an arc that rests against the wearer's chin when the handset set is put on. Moreover, it has a certain distance from the neck due to the bending. This optimum expansion under minimal preload is achieved when the spacing between the receiving surfaces of receivers 2a, 2b is 15
0 mm, and the U-shaped member portion below the hinge point 9 is 5 mm.
It is produced when tapering under an angle of ˜10′. Said arc extends approximately at the level of the Adam's apple. Of course, not all head shapes are the same in terms of their size, especially the width between the ear shells.

These various differences are overcome by the prestressing of the U-shaped element 6, in which case the spring properties of the U-shaped element 6 have an overall softer characteristic. That is, the preload does not increase substantially even with extremely large heads. As a result, the receivers 2a, 2b are transmitted to the wearer's outer ear shell.
crimping is not affected. This is because the introduction of force takes place mainly by the ear straps 3a3b, but not only by the ear straps. This makes it possible to confirm that the receivers 2a, 2b do not apply pressure to the wearer's outer ear shell. The wearing comfort of the handset set as well as the assistance with respect to the force introduction of the preload of the U-shaped member 6 is increased by another measure already mentioned, namely in the form of the cushion 16a. This cushion supplements the holding body la1b in the area of the protruding receivers 2a, 2b on the side of the earshell and thus compensates for the difference in height between the hole in the earshell and the anterior ear projection, and This assists in introducing the force of the preload of the U-shaped member 6, which is taken up by the ear straps 3a3b.

In order to more easily attach the handset set, the ear straps 3a and 3b are attached to the organ side and head side.
Approach edges 17a/17b, 18a/18b, 19a/19
The entry edges 17b and 19a, which in this case are not shown in FIG.
This is the approach edge belonging to 9b.

The embodiment shown in FIG. 2 differs from the embodiment shown in FIG. 1 in that the set shown in FIG. Strictly speaking, it's not a handset set. However, the other configuration corresponds to that of the embodiment shown in FIG.

3 and 4 show the back sides of both holders 1a and lb. One holder 1a has an on/off switch 13 for the corresponding receiver, and the other holder 1b
In contrast, it has a reception operation button I2. With both configurations, one or both receivers 2 a
+2b's reception function can be arbitrarily controlled.
In the figure, the holding body 1a is shown in a bird's-eye view in the holding direction. The freely extending ear strap 3a has an angle X of 7° to 13° with respect to the front receiving surface 15 of the receiver 2a.
in this case the earshell surface 14 of the ear strap 3a remains somewhat concave. In the mirror image profile, the above also applies to the other holder 1b, receiver 2b and ear strap 3b.

FIGS. 6 and 7 show the set shown in FIGS. 1 and 2, respectively, in an installed state.

As can be seen particularly well in the handset set shown in FIG. It is located at the height of the angle. With this configuration, there is an advantage that the microphone strap 7 does not obstruct the wearer's view.

Furthermore, the internal curvature of the microphone strap 7 is kept somewhat concave in accordance with the curvature of the face in this section, so that the microphone strap does not protrude either and is therefore mechanically unobtrusive.

FIG. 6 also shows the location of the ear shell hole 20 and the anterior ear projection 21, which have already been described in various ways.

In this way, the various procedures conditioned by the ear strap, i.e. the bending, the ultimate purpose of the entry edge, can actually be felt when worn.
