Abstract

A radio headset allowing a certain rotation of the ear pieces 3 comprises a headband 1 having two support members 11, a pair of adjustable strips 2 each slidably connected with one of the support members 11 and a pair of regulating members 21 each carrying a protrusion 23. A pair of ear pieces 3 each has a housing 31 formed at the upper portion thereof with a chamber 351 having at the top a hole 311 communicating with the chamber and adapted for receiving the L-shaped protrusion 23. The chamber of the housing 31 is covered with a limit plate 33 having a protuberance 331 inserted into the hole 311 of the housing 31 and designed to limit the housing 31 to rotate within a predetermined range. <IMAGE>

Description

SPECIFICATION Adjustable radio headset The present invention relates to an adjustable radio heedset 3r.c an particular to one utilizing the protrusion of the regulating member to cooperate with a protuberance of the limit plate to allow a certain rotation of the ear pieces.

As is well known, the ear pieces of most prior art radio headsets can be adjusted in height but cannot be rotated with respect to the perpendicular plane along the length of the headband However, the ears of everybody are positioned differently and so the headsets cannot satisfactorily adapt to the needs of everybody. Accordingiy, many kinds of different headset constructions have been proposed to allow a certain rotation of the ear pieces of such headsets.

Nevertheless they are relatively expensive to manufacture and do not permit sufficient rotation of the ear pieces.

It is, therefore, an object of the present invention to provide a headset which may obviate and mitigate the above-mentioned drawbacks.

It is the primary object of the present Invention to provide an adjustable radio headset which is Intended to be worn comfortably.

It is another object of the present invention to provide an adjustable radio headset of which the ear pieces can be rotated with respect to the perpendicular plane along the length of the headband by means of the protrusion of the regulating member in association with the protuberance of the limit plate.

It is still another object of the present Invention to provide an adjustable radio headset which is simple in construction.

It is still another object of the present @ Invention to provide an adjustable radio headset which Is compa ratively inexpensive to manufacture.

It isa further object of the present Invention to provide an adjustable radio headset which is easv to assemble.

The above and other oblects and acívantages of the present Invention will appear more fully hereinafter from a consideration of the detaiied description which follows taken together with the accomnanving drawings wherein like numerals refer to like or similar Darts and In whicn FIG. 1 is a perspective view of an 3dlustable radio headset according to a preferred embodiment of the present invention FIG. 2 is an exploded view of the adjustable radio headset; FIG. 3 is an enlarged fragmentary view of the adjustable radio headset; FIG. 4 is a selectional view taken along line A-A of FIG.

3; and FIG. 5 is a fragmentary view showing that the ear pieces have been rotated with respect to the perpen ilicrilar plane along the length of the headband of the adjustable radio headset.

While the present Invention its susceptible of embodiment In various terms. there Is shewn In the drawings and will hereinafter be described a presentiv preferred embed ment of the Invention, with the understanding that the present disclosure is to be considered as an exemplification ofthe invention, and is not intended to limit the invention to the specific embodiment illustrated.

With reference now to the drawings and in particular to FIG. 1 thereof, there is shown an adjustable radio headset embodying the principles of the present invention. As illustrated, the adjustable radio headset comprises a generally inverted U-shaped headband 1 and a pair of ear pieces 3 each attached to the downwardly depending ends of an adjustable strip 2.

The adjustable strip 2 Is slidablyconnected to the headband 1 through a support member 11 which is integral with the headband 1. The downwardly depending ends of the adjustable striD 2 Is provided with a regulating member 21 having a L-shaped protrusion 23 at its bottom.

Referring to FIGS. 2, the ear piece 3 inc!udes a housing 31 formed at the upper portion thereof with a chamber 351 and at the top thereof with a hole 311 communicating with the chamber351 and adapted for receiving the L-shaped protrusion 23. Accordingly, the housing 31 can be rotated with respect to the perpendicular plane along the length of the headband 1.

The chamber 351 of the nousing 31 is covered with a limit plate 33 which has a protuberance 331 inserted into the hole 311 of the housing 31 thereby limiting the housing 31 to rotate within a predetermined range (see FIGS. 3 and 4). The chamber 351 is further provided wite a number of protuberances 32 for supporting the limit plate 33.

Dispose(i within the housing 31 Is a loudspeaker 4 on which there is mounted a cover 34. The cover 34 Is formed with a number of slots 341 for faithfully transmitting the sound from the loudspeaker 4 to the ear of the audience. Further, a cushion 35 generally made of sponge is used to enclose the outer surface of the cover 34.

Accordingly, the ear piece 3 of the adjustable radio neadset according to the present inventiOn can be rotated with respect to the perpendicular p one along the headband 1 so that the present Invention is suitable for individuals even having wide variations in physical characteristics. Moreover, the adjustable radio headset can be reduced in volume therebv facilitating the transportation thereof.

From the foregoing, it will be observed toot numer - ous variations and modifications may be effected without depart ng from the true spirit and sape of the novel concept of the present invention. It will be understood that no limitations wit respect to the specific article lust rated herein Is intended or should be inferred. lt is, of course, Intended to cover ov the appended cia os all sich mod if catic os as fall il wi ti toe scope of the claims.
