INVENTOR. EIQIVIEL A 4N4- HEARING AID CONTROL MOUNTING This invention relates to apparatus for mounting ,the main control elementof a hearing aid within a surface plate of the unit such'that the control may be removed for proper servicing thereof but providing structure which will prevent the inadvertent removal or breakage of the control knob by the user. The device basically consists of a mounting ring element receivable into a surface of the hearing aid having a switch receiving area defined therein wherein a portion of the mounting element will be, provided with an upstanding protective ring circumsoribing the switch knob to prevent persons from accidentally pulling the control knob from the switch while still permitting proper operation of the switch.
During the last several years the refinement of hearing aids has resulted in what is now known as the in-the-ear aid which consists of a complete .energizeable package insertable into the canal and outer car which requires no external wiring and the like. These units are basically completely enclosed and contain their own b'attery source of power. Naturally with any device aid in hearing it is necessary to control the amplification of the device and certainly to conserve on the energy of the'battery source it' is desireable to provide an an on-off mechanism for deenergization of the aid when notin use. On
the in-the-ear aids this control is usually a-single control element having an external control knob for operation by the user and the normal method of providing these control switches in the aids is to directly glue or otherwise adhere the switch to an aperture in the aid..This switch locating is usually accomplished with the aid of adhesivesand should service be required it is often necessary to completely destroy the aid in order to service an inoperative switch.v
Another difficulty with "glued in" switches is their protrusion from the surface of the aid. This protrusion is undesirable as very often the user will grasp the knob and being able to place his fingernails thereunder often tears the knob from the switch, thereby requiring replacement of the entire switch.
it is therefore an object of applicant's invention to provide a mounting structure for control switches on hearing aids and the like wherein the use of adhesives is eliminated while retaining the switch in proper position-on the aid and allowing proper removal thereof only when required for servicing and the like. o I I It is a further object of applicants' invention. to provide a protective device for the control knob of a-hearingaid control switch which'will prevent the user from grasping the entire knob but permitting the user to properly turn, the switch and operate the hearing aid device. i w
It is still a further object of ap'plic'a'nts device to provide a structure which will permit ease of mounting and removal of control switches for hearing aids and the like.
These and other objects and advantages of my invention will more fully appear from the following description made in connection with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the several views, and in which:
FIG. 1 is a side elevation of an in-tl 1e-ear hearing aid embodying the concepts of applicants invention; r
FIG. 2 is an elevation of the device viewed from the exposed side when mounted in the ear; Y
FIG. 3 is a vertical section take taken substantially along 'line 3-3 of FIG. 2 illustrating the switch mounting portion of the hearing aid;
FIG. 4 is a top plan view of the switch mounting portion of the device; and
FIG. 5 is a bottom plan of the mounting device.
In accordance with the accompanying drawings, the hearing aid generally designated illustrating an in-the-ear construction is generally well known in the art and includes a frontal portion 11 thereof receivable into the outer ear canal and defining a cavity therein which contains the electrocircuitry required for the operation of theaid. A rear closure plate 12 is provided-to close the cavity and this plate 12 is often directly adhered to a rcarmost surface of the cavity 11. such that the unit is basically sealed. 7
. i the electrical circuit within the aid. In the form shown five of As illustrated the control section generally designated. 13 is arranged on and within the plate 12 halving a mounting ring structure 14 and a control switch designated generally 15 with a control knob 16 thereof extending outward from the plate 12 and the actually switch body 17 arranged within the ring 14. In this manner the control knob 16 is accessible to the user but as illustrated in FIG. 3 the control knob 16 is recessed within the control knob mounting-ring 14 to basically prevent anyone from grasping the control knob 16 or inserting something therebehind to pry'the same from the switch 15. This prying could be the result of a person grasping the knob and having his fingernails reach therebehind and the recession of the knob 16 within ring 14 will prevent this.
In the form shown the mounting ring includes a generally cylindrical body portion 18 defining a cylindrical longitudinally extending cavity 19 therein. The length of this cavity '19 is controlled by an inwardly projecting ring 20 at the lowermost end of the housing 18 and within this ring 20 a plurality of spaced radially outwardly extending slots 21 are provided. The total longitudinal length of the mounting member 14 is designed to coincide with the thickness of the plate 12 and at the uppermost end of housing 18 an outwardly extending ring 22 is provided having alower shoulder 23 to abut with the upper surface of the plate 12. This outward extending ring 22 is of slightly greater inner diameter than. the 22a diameter of the longitudinal passage 11! of the housing 18 such that the knob portion 16 of the switch 15 which'is slightly larger than the switch body portion 17 is free to rotate within the confines of the inner circumference 22a of the ring 22. The length of the cavity 19 is also controlled such thatthe switch portion 17 will bottom against the inwardly extending ring 20 with the knob portion 16 thereof arranged in slightly longitudinally spaced relation from an uppermost shoulder 24 of ring 14 which shoulder 24 extends to the inner circumference 22a of the ring 22. With thisarrangement thecontrol knob portion 16 of the switch 15 isfree to rotate through its various positions without binding or rubbing on any of the portions of the mounting ring 14. While such rotation is permitted it is also il lustrated that the height of the ring 22 is -such that it is spaced slightly above the bottom surface of the control knob 16 such that it is not normallypossible to insert anything behind the control knob 16 unless removal isabsolutely desireable.
The dimensions between the circumference of the control ring 14 and the switch 15 are such that an interference fit is provided and for this purpose the ring may most desirably be formed of a resilient material. In this manner a dual interference fit is provided which will hold the ring 14 within the plate 12 and will hold the switch body" 17 within the internal cavity]? of the switch mountingring 14. This, of course,.is
necessary to prevent the switch from falling from the aid and to hold the switch body 17 against rotation when the knob 16 is turned. 1
Normally the switch provided with the in-the-ear" aids include a plurality of contacts 25 extending from the bottom thereof. The aforementioned slots 21 provided at the bottom most portion of the housing 18 extending radially outwardly into the ring 20 are designed to specifically receive these contacts and allow them to be connected to the proper portions of such slots are provided. but it should be obvious that any number of slots to match the number of contacts on the switch would be provided.
As should be obvious this particular type of construction permits an ease of assembly for mounting control switches in hearing aids as compared to previous methods wherein a flat bottom hold was bored partially through. the plate 12 and a outwardly from theplate 12 to an undesirable height. Further,
in this type of construction soldering of the contacts is simplified as all soldering may be done away from the plate 12 with assembly completed after soldering as compared with the old method wherein the switch had to be inserted into the plate 12 properly glued therein and soldering done thereafter.
It should be obvious that applicant has provided a new and unique hearing aid control mounting method and structure which permits simplicity of assembly of the control portions for hearing aids while insuring that the control knob of the control portion is properly depressed within the structure to prevent its being torn from the structure while still permitting ease of operation for the user.
It will, of course, be understood that various changes may be made in the form, details, arrangements and proportion of parts without departing from the scope of the invention, which generally stated consists in the matter set forth in the appended claims.
