## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This nonprovisional application claims the benefit of U.S. Provisional Application No. 61/550,931 filed Oct. 25, 2011, and claims priority under 35 U.S.C. 119(a) to Patent Application No. 11186431.0 filed in Europe on Oct. 25, 2011, all of which are hereby expressly incorporated by reference into the present application.


BACKGROUND OF THE INVENTION
The invention is related to a hearing aid retainer accessory for retaining a BTE (behind-the-ear) hearing aid at a user's ear.
In order to operate at best and to prevent damage resulting from falling of the ear and dropping to the ground, a BTE-hearing has to be kept in a safe position at a user's ear. Even so if the user's head moves intensely as is the case doings sport. Another example is a child playing.
US 2007/0217641 A1 discloses a hearing aid protection accessory formed by a flexible sleeve to be wrapped around a housing of a hearing aid, the flexible sleeve to be connected to a users clothing via a clip and a cord. Suitable for preventing the hearing aid from dropping to the ground this arrangement, however, does not allow an adjustment to a user's ear and is likely to entangle with all kinds of obstacles a child may encounter playing. Also the sleeve adds to the thickness of the hearing aid housing rendering it difficult to be placed behind a small ear.
U.S. Pat. Nos. 4,881,616 and 4,702,345 each disclose a hearing aid retainer accessory that is formed by a tube with a respective sleeve connected to each end, both sleeves pulled over the housing of the hearing aid. The arrangement disclosed in U.S. Pat. No. 4,881,616 allows an adjustment to a user ear by moving the sleeves toward or away from each other on the housing of the hearing aid. The degree of adjustment, however, is limited by the longitudinal dimension of the hearing aid housing. The sleeves of both U.S. Pat. No. 4,881,616 and U.S. Pat. No. 4,702,345 add to the thickness of the hearing aid housing, resulting in a discomfort to wear or even the ears protruding, provided they are still in a process of growth. Furthermore, the sleeves are likely to interfere with a control button located at the surface of the hearing aid housing.
U.S. Pat. No. 7,013,018 B2 discloses an adjustable earring for a headset, the earring being connected via a pivotal link to a housing of a speaker included in the headset.
Finally, U.S. Pat. Nos. 4,918,757 and 3,327,807 each disclose an arrangement for retaining a hearing aid at a user's head utilizing a head band. Undesirably each of the arrangements exerts an uncomfortable force to the users head and is rather noticeable.
It is therefore an object of the present invention to provide a hearing aid retainer accessory which avoids the disadvantages of prior art devices and is intuitive and easy to attach, comfortable to wear, free of interference with a hearing aid's control buttons and the specially designed hearing aid geometry, all while retaining a hearing aid at a user's ear safely and stably.
A hearing aid in the scope of the present invention is a BTE-hearing aid or a BTE-like-hearing aid.
SUMMARY OF THE INVENTION
According to a first aspect of the present invention the technical object is achieved by a hearing aid retainer accessory for use with a hearing aid that comprises a battery compartment to be fitted with a battery drawer, wherein the hearing aid retainer accessory comprises a retainer portion with a connection section that is adapted to be engaged with a hearing aid via a battery drawer.
According to a second aspect of the present invention the technical object is achieved by a hearing aid and hearing aid retainer accessory attached thereto. The hearing aid comprises a battery compartment to be fitted with a battery drawer. The hearing aid retainer accessory has a retainer portion with a connection section that is engaged with the hearing aid via a battery drawer.
Engageable or engaged to a hearing aid via a battery drawer, the hearing aid retainer accessory is free of interference with a hearing aid's control buttons and the specially designed hearing aid geometry. Furthermore, the hearing aid retainer accessory is very intuitive and easy to attach to a hearing aid.
It is understood that the embodiments and their advantages described hereafter apply to both the first and the second aspect of the present invention.
In a preferred embodiment, the hearing aid retainer accessory comprises a battery drawer. The battery drawer is adapted to complement a hearing aid's battery compartment. This adds to the easiness of use.
To allow an efficient fabrication and enhanced sturdiness, the retainer portion and the battery drawer can be formed as an integral single piece. In this embodiment the battery drawer constitutes the connection section. The battery drawer can comprise a hinge to be connected to a corresponding hinge pin comprised by a hearing aid's battery compartment, allowing the battery drawer to be swiveled in order to replace its battery.
Alternatively the retainer portion can be releasably connected to the battery drawer. The battery drawer can comprise a coupling means adapted to be connected to a corresponding receiving means comprised by the connection section. The retainer portion is changeable without having to change the battery drawer itself, which is of a particular advantage if the user's ear is still in a process of growth requiring the retainer portion to be changed more often.
In a further alternative embodiment the connection section is adapted to be clicked on a battery drawer as part of a hearing aid. Advantageously the hearing aid retainer accessory can be engaged with a hearing aid via a battery drawer without having to consider changing the battery drawer at all.
In a preferred embodiment the retainer component has a hook-like shape. In light of experience a hook-like shape is especially discreet and comfortable to wear. The retainer component can be configured to be deformable. Provided as a straight elongated portion it can be bent into a desired shape fitting the user's ear geometry best. The retainer element can be spring-like. This has the advantage that the retainer element returns into its original position after having been pushed out for attachment. To provide an especially robust wear for children, the retainer element can be provided a ring going all the way around the ear, the ring being elastic or non-elastic. Alternatively the retainer component can be configured to have a firm shape.
