5), JOHN 1'? P055 Arromvrrs This invention relates tospectacle-mounted hearing aids, 'and'more specifically relates to the source of power in such hearing aids and the control therefor.

Although there has been a trend in the recent past to miniaturize the several components of such hearing aids, it has been necessary'to provide manual controls of such size as to facilitate ready and easymanipulation thereof. The problem-of providing easily"man ipulatable controls becomes particularly acute when the complete hearing aid unitis mounted in .one of, the temples of the'spectacles; An object of my invention is the provision 'of'a new and; improved{ ternp'lemounted hearing aid control of p simple-and inexpensive ;confstruc'tion and operation;

Another fobjeet of my inventionis to provide a novel" temple-mountedhearingaid-control adapted to be readily and 'easily moved between a pluralityyof"positions by" manual'iirgin --a gainstenga'geablefsurfaces which closely i g followv the ge'neral surface contour-of the" temple and 7 which are nemau-y'aispesedin an out-of the-way position.

is constructed to I contaiml and actually: does contain, the

components and circuitry of a complete hearing aid 'u'nit which includes, in general, a transmitter T, a transistor amplifier A, a receiver R, and a power supply P. The general locationof these major components in one of the portions 14 is shown in Fig. l. The forward end portion 15 'of the rigid member 13' is connected by means of a hinging'structure 16 to the spectacle frame 11.

The rear endportion -17 of the rigid member 13 defines a multi-sided interior'compartment 18 which has closed top and

outer sides

19 and 20 respectively defined by portions integral with the rear portion 17 of rigid member 13, and a closed inner side or cover plate 21 which is seated on shoulder surfaces 22 and which is retained in stationary relation as by

screws

23 and 24. The compartment 18'has a pair of elongate

open sides

25 and 26 which respectively open in downward and rearward or upward directionsand which may be described as lying transversely of the'inner side or cover plate 21 at the rear tip of the temple; The

open sides

25 and 26 of the compartment 18 are disposed at acute angles with-respect to each other.

A swingable battery carrier and switch-operator 27 is provided in thecompartment 18,-and has a cylindrical chamber 28 therein toreceive and carry a substantially cylindrical battery 29-. The carrier 27 has an inner side 27a confined within the compartment 18 and has a pair of elongate andgenerally linear outer sides 27b and 270 which arerespectively disposed at the open sides 25 and 26 'of "the compartment 18 and exteriorally exposed through the .opensides of the compartment. In Fig. 2 it will belseenthat in this form of the-invention, the exposed

sides

27b and 27c of the carrier are oriented at an acute angle with respect toeach other which is slightly larger than the-acute angular relation between the sides I 25"and 2 6of the compartment so that the corresponding side 27 normally projects slightly outwardly beyond the open side26 of the compartment, but in any event the exposed sides 27b and 2700f the carrier generally follow the contour of the rear portion 17 of the rigid member 13.

Means are provided for swingably mounting the carrier 27 in the compartment, and in the form shown, a mounting post 30 is formed integrally with the outer side wall 20 of the compartment and is positioned adjacent the rearwardly projecting corner between the angular open sides 25 fand-26ff Threaded insert 31 is provided in the post 30, and thescrew 23 is' threadably secured in the insert 31 and a smooth neck portion 236: of the screw projects through and swingably mounts the carrier 27 in a suitably provided bearing aperture 27d. It Will be seen that the open side 25 Yet the compartment 18 is of such dimensions as to permit swinging of the entire carrier outwardly therethroughuso as to facilitate replacement of thebattery 29. The-carrier 27 'incorporates a small forwardly projecting lip 27e which-may be manually gripped to assist in outward (counterclockwise in Fig. 2) swinging of the carrier. The top side 19 of the compartment and the carrier 27 have matching and spaced

abutment surfaces

27 f and 19a which engage each other and prevent outward swinging of the'carrier' in a clockwise direction and through the open side 26.

The battery 29 has a substantially cup-shaped housing 32 defining an outer cylindrical terminal surface 33 and the battery also has another terminal surface portion 34 at the bottom thereof.

A generally triangularly shaped recess or cavity 35 is provided in the outer side 20 of the chamber, and spring contacts 3.6 are positioned in the cavity 35 to engage the 36 when the carrier is swung outwardly.

A second spring contact 39 is also mounted on the rib 38 as by a screw 40 and the spring contact 39 is arranged to engage the inner side 27a of the carrier 27 to project through an opening 41 therein for engagement with the terminal surface 33 of the battery. It will be seen that the end of switch contact 39 is substantially V-shaped to provide a detent and camming surfaces to lift the spring contact 39 out of the detent-receiving opening 41 and out of engagement with the battery 29 when the carrier is moved from the position shown in Fig. 2 to the position shown in Fig. 3. A detent-receiving notch 42 is also provided in the inner side 27:: of the carrier to receive the spring contact 39 as seen in Fig. 3 so as to retain the carrier against accidental movement when the carrier has been shifted to disengage the battery from the spring contact 39.

In operation, a battery is normally contained in the chamber 28 as seen in Fig. 4. When the hearing aid contained within the rigid member 13 is to be operated, the carrier 27 is positioned as shown in Fig. 2 so that the contact 39 engages the battery 29. Power is supplied by the battery through the spring contacts 39 and 36 and through the wires 43 to the hearing aid circuitry so as to permit operation of the hearing aid. When the hearing aid is to be turned ofii, the spectacles will most likely, but not necessarily, be removed from the users head. With the thumb and fore finger, the user may easily engage the exposed sides 27b and 270 and the adjacent portions of the rigid member 13 at the rear portion 17 thereof and manipulate the carrier 27 to the position shown in Fig. 3, whereupon, by camming action the spring contact 39 is moved out of engagement with the battery and subsequently, the spring contact 39 drops into the notch 42 to retain the carrier against additional outward swinging.

When the hearing aid is to be rendered operative again, the carrier is again manually manipulated by engaging the side 2711 and urging the carrier back to the position shown in Fig. 2.

The accessibility and ease of manual operation of this control for the hearing aid circuitry is emphasized. Battery 29 may be approximately one-half inch in diameter and therefore, with the carrier 27 being correspondingly proportioned, no trouble at all is encountered by a person in properly engaging and manipulating the carrier to perform the switching operation. It should be further noted that because the manually engageable exposed sides of the carrier follow the general configuration or contour of the tip of the template it is quite unlikely that the carrier or switch operator will be accidentally moved and it is further unlikely that any portions of the carrier will become entangled with a persons hair or the like. The slight rearward projection of the side 270 of the carrier makes shifting of the carrier extremely easy when the hearing aid is to be turned off. When the spring contact 39 drops into the notch 42, the side 270 is substantially parallel with the edges of the inner and

outer sides

21 and 20 respectively so that normally it is quite unlikely that the carrier will be moved further than is necessary.

If the battery 29 is to be replaced, the carrier 27 is swung outwardly beyond the position shown in Fig. 3 and the entire chamber 28 will be disposed outwardly from the open side 25 and the battery may be easily slipped out of the chamber 28 and another battery may be inserted. The carrier 27 will then be swung back into the compartment 18.

It will be seen that I have provided a new and improved hearing aid temple construction wherein the battery and mounting therefor, which are of substantial size and may be easily manually manipulated, are employed as a switch operator. It should further be seen that because of the dual functions of the battery and battery carrier, miniaturization of the general hearing aid construction is facili tated with provision being made for relatively large manually engageable and manipulatable control parts.

It will, of course, be understood that various changes may be made in the form, detail, arrangement and proportion of the parts without departing from the scope of the invention which consists of the matter described herein and set forth in the appended claims.
