Abstract

Abstract Interconnecting means for the transition piece or auricle mounting unit of a behind-the-ear hearing aid and the nozzle of the hearing aid comprising radial lugs on the nozzle of the hearing aid and radial recesses in the tubular passage of the transition piece or auricle mounting unit wherein the elastomeric construction of the auricle mounting unit permits a relatively low application force to apply the auricle mounting unit to the nozzle of the hearing aid and interengage the radial lugs of the nozzle with the recesses of the passage in the auricle mounting unit while nevertheless a higher retention force is achieved requiring a greater force to remove the auricle mounting unit thereby providing protection against accidental separation of the nozzle and while nevertheless providing protection against accidental misuse by permitting the elastomeric auricle mounting unit to deform and slip off the lugs in the case of application of force in excess of a predetermined force.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 93 words
A behind-the-ear hearing aid comprising: a hearing aid body, a nozzle extending from one end of said hearing aid body, an auricle mounting unit having a passage therethrough, radial lugs extending from said nozzle, corresponding radial lugs in said passage of said auricle mounting unit adjacent an end of said passage and said unit, said auricle mounting unit and the internal wall of the passage thereof being elastically deformable, said radial lugs engaging when said auricle mounting unit is placed onto said nozzle and toward the said end of said hearing aid body.
Claim 2
Dependent Claim 93 words
A behind-the-ear hearing aid comprising: a hearing aid body, a nozzle extending from one end of said hearing aid body, an auricle mounting unit having a passage therethrough, radial lugs extending from said nozzle, corresponding radial lugs in said passage of said auricle mounting unit adjacent an end of said passage and said unit, said auricle mounting unit and the internal wall of the passage thereof being elastically deformable, said radial lugs engaging when said auricle mounting unit is placed onto said nozzle and toward the said end of said hearing aid body.
Claim 3
Dependent Claim 38 words
The hearing aid of claim 1 wherein, said end of said auricle mounting unit and said end of said hearing aid body meet and form a continuous unit when said auricle mounting unit is secured on said nozzle.
Claim 4
Dependent Claim 47 words
The hearing aid of claim 2, wherein, said hearing aid body is curved and said auricle mounting unit is curved on an extension of the curve of the hearing aid body forming a continuous unit having a continuous curve adapted to hang together on a human ear.
Claim 5
Dependent Claim 36 words
The hearing aid of claim 3 in which the end of the auricle mounting unit opposite the end thereof connected to the hearing aid body is provided with means for receiving and securing a tube thereto.
Claim 6
Dependent Claim 20 words
The hearing aid of claim 1 wherein an acoustic seal is effected by the face-to-face abutment of the transition piece.
Claim 7
Dependent Claim 24 words
The hearing aid of claim 1 wherein an acoustic seal is effected by diametral interference of the hearing aid nozzle and the transition piece.
Claim 8
Dependent Claim 106 words
The hearing aid of claim 1, wherein each said radial lug in said passage of said auricle mounting unit extends only partially around the circumference of said passage, thereby defining gaps about said passage circumference between neighboring said radial lugs in said passage; said radial lugs extending from said nozzle being oriented about the periphery of said nozzle so as to be alignable with said gaps between said radial lugs in said passage, whereby said radial lugs extending from said nozzle can be moved into and through said passage past said radial lugs in said passage when said auricle mounting unit is placed onto said nozzle.
Claim 9
Dependent Claim 24 words
The hearing aid of claim 1, wherein said radial lugs extending from said nozzle and said radial lugs in said passage are elastically deformable.
