Patented Dec. 26, 1950 CLIP FOR HEARING AID CASES Elroy W. Born, Minneapolis, Minn., assignor to The Maico Company, Incorporated, Minneapolis, Minn., a corporation of Minnesota Application January 10, 1949, Serial No. 70,032

2 Claims.

My invention relates generally to spring clips and, more specifically, to means for securing hearing aid casings and the like to a pocket or other portion of a wearers garment.

The primary object of my invention is the provision of highly efficient and yet inexpensive means for securing hearing aid casings and the like to the pocket or other portion of the garment of the wearer.

Another highly important object of my invention is the provision of means, whereby fastening means may be quickly and inexpensively secured to and removed from a hearing aid casing or the like without the use of any special tools.

The above and still further objects of my invention will become apparent from the following detailed specification, appended claims, and attached drawings.

Referring to the drawings, wherein like characters indicate like parts throughout the several views:

Fig. 1 is a fragmentary view in front elevation, illustrating the use of my novel clip in securing the hearing aid casing to the pocket of a garment;

Fig. 2 is a view in side elevation of a hearing aid casing with my novel clip applied thereto, some parts broken away and some parts shown in section;

Fig. 3 is an enlarged fragmentary detail as seen from the line 3-3 of Fig. 2; and

Fig. 4 is a view in perspective of one of the casing sections of a hearing aid casing, one of the clips of my invention applied thereto and one removed therefrom.

Referring with greater particularity to the drawings, the numeral l indicates, in its entirety, a casing for hearing aids or the like comprising front and rear shell-like sections 2 and 3 respectively, as shown, the front section 2 being provided with a lip or flange 4 which is telescopically received within the peripheral edge portion or lip 5 of the rear section 3.

One of the sections, preferably and as shown, the front section 2, is provided, in its opposite side walls 6 and l, with notches 8 which extend inwardly from the edges thereof toward the front wall 9. The casing sections 2 and 3 are preferably formed from plastic or other molded material and in any event are provided with recesses IS on the interior of the side walls 6 and l which extend downwardly from the notches 8.

The numeral ll indicates, in their entireties, generally U-shaped spring clips which, preferably and as shown, are each provided with one relatively long leg I2 and one relatively short leg i3. The relatively short leg l3, intermediate its extreme ends, is provided with an angular portion it which, as shown, is adapted to extend transversely through one of the notches 8. De-

pending from the portions it are foot portions it which are of a size to be snugly received within the recesses I 0.

When it is desired to apply the clips II to the casing I, the sections 2 and 3 are separated and the clips 5 l are applied to the front section 2 by inserting the angular section ll; laterally into the notches 8 so that the feet !5 come to rest within the recesses I0. It will be seen that, when the spring clips H are thus positioned, the longer legs I2 make frictional engagement with the exterior of the side walls '6 and I below the lower end of the feet l5. It will be obvious that, when the rear casing section 3 is applied as shown in Fig. 2, so as to close the notches 8, the spring clips II are retained within the notches 8 against accidental removal. In fact, removal can be accomplished only by separation of the sections 2 and 3. It wil be understood that the casing sections 2 and 3 may be locked together by means not shown, such means forming no part of the instant invention.

It will be seen, by reference particularly to Figs. 1 and 2, that spring clips II are locked in close proximity to the top of the casing I so that the greater part of the weight of the hearing aid lies below the clips II. The clips ll thus located permit insertion of the hearing aid casing I into a pocket indicated at :1: in Fig. 1 to substantially the entire depth thereof, with the legs 52 of clips 5! engaging the wall of the pocket :1: to prevent the hearing aid from accidentally fallin outwardly therefrom.

While I have shown a preferred embodiment of the invention, it will be understood that the same is capable of modification without departure from the spirit and scope of the invention as defined in the claims.

What I claim is:

1. In a device of the class described, cooperating front and rear casing sections, one of said sections being provided with a notch in one side wall thereof, a recess on the interior of said wall adjacent the edge thereof extending downwardly from said notch, and a generally U- shaped spring clip, one leg of said clip being provided with an angular portion intermediate its ends adapted to extend through the notch in said casing section, and an offset foot receiv- 3 4 able in said recess, the other leg of said clip REFERENCES CITED friitfionauy engaging the exterior Wan of said The following references are of record in the Sec file of this patent:
