DETAILED DESCRIPTION OF THE DRAWINGS
Referring now in detail to the drawings for the purpose of illustrating preferred embodiments, different views of a hearing aid device 2 is illustrated in FIG. 1.
FIG. 1a) illustrates a schematically side view of a behind-the-ear (BTE) hearing aid device 2. FIG. 1b) illustrates a close up side view of the hearing aid device 2 shown in FIG. 1a).
The hearing aid device 2 comprises a housing 4 and a hook 8 that is attached to the distal end of the housing 4. It is important to underline that the illustration of the hearing aid device 2 is simplified for illustration purposes. Accordingly, a number of the standard elements such as the amplifier, speaker and microphone of the hearing aid device 2 are not shown in any of the drawings.
A battery drawer 24 is hinged to the housing 4. The battery drawer 24 comprises a battery compartment 12 shaped to receive and store a cylindrical battery (not shown). The battery drawer 24 comprises a battery door 6 provided with three transversal indentations 18 in its outer surface constituting a finger engagement portion 26. The indentations 18 are intended to provide an enhanced grip or traction when engaged by a finger of a user. Accordingly, the indentations 18 makes the finger engagement portion 26 easier to use for the user of the hearing aid device 2.
The battery drawer 24 has a body portion 38 that is basically flat (the surface has a slightly circular arced cross-section). The battery drawer 24 comprises a nail grip member 28 that includes the most distal portion of the finger engagement portion 26. The nail grip member 28 protrudes from the body portion 38. The user of the hearing aid may open the battery drawer 24 by placing a nail under the nail grip member 28 and forcing the battery drawer 24 to open. The battery drawer 24 is rotably mounted to the housing 4 by means of two shafts 14 that are received in corresponding bores within the battery drawer 24.
A spring 16 is fixed to the inside surface of the housing 4. The spring 16 is configured to provide a force that causes a clockwise rotation of the battery drawer 24, i.e. pivot the battery drawer 24 at the shafts 14. The force provided by the spring 16 can be used to push back the battery drawer 24, when the battery drawer 24 has to be opened (e.g. for battery replacement).
The battery drawer 24 comprises a pin member 20 that is rotably arranged in a corresponding channel 10 provided in the housing 4. The pin member 20 has a longitudinal axis X, while the channel 10 has a longitudinal axis Y that extends parallel to the longitudinal axis X of the channel 10.
The pin member 20 is shaped as a rod that is attached to a slightly curved base member 34 that is provided with a head 36 protruding from the distal end of the basically plate-shaped base member 34 (see FIG. 3b for a more detailed view).
The housing 4 has a groove 32 configured to receive the nail grip member 28 of the battery drawer 24. The geometry of the groove 32 fits the geometry of the nail grip member 28 of the battery drawer 24.
The battery drawer 24 has a built-in on/off function. A change between an “on-state” and an “off-state”, respectively, is established by changing the position of the battery drawer 24 relative to the housing 4.
FIG. 2a) illustrates a schematic close-up view of a hearing aid device 2. The hearing aid device 2 corresponds to the one shown in FIG. 1. In the illustrated configuration the hearing aid device 2 is in an “off-state”. The top surface of the finger engagement portion 26 is in this state positioned at a distance d3 above the top surface 44 of the housing 4.
In the figure it is seen that when the battery door 6 is at least partly open, the distance between the nail grip member 28 and the top surface 44 of the housing 4 is h. It may be preferred that h is at least 1 mm, so that the nail grip member 28 may be opened by using a nail.
FIG. 2b) and FIG. 2c) illustrates schematically close-up views of the hearing aid device 2 shown in FIG. 2a). The finger engagement portion 26 has been pushed towards the central portion of the housing 4. The top surface of the finger engagement portion 26 in this state is positioned at a distance of d2 above the top surface 44 of the housing 4 in FIG. 2b) and in a distance d3 above the top surface 44 of the housing 4 in FIG. 2c). When comparing FIG. 2a), FIG. 2b) and FIG. 2c) it can be seen, that d3 is larger than d2 and that d2 is larger than d1.
In FIG. 2a) the head 36 of the base member 34 is arranged in the lowest portion of the engagement portion 40 and engages a cam surface 42. As long as the position of the finger engagement portion 26 is unchanged, the hearing aid device 2 will be maintained in the “off-state”. Cam surface 42 is shaped as a cam member provided in the engagement surface by recessing a part of the surface 40.
However, in FIG. 2b) the finger engagement portion 26 has been pushed down, i.e. closer to the housing, and has been arranged in an “on-state”. It may be seen that the head 36 (indicated with a dotted line) of the base member 34 is in contact with cam surface 42 and positioned in the central region the engagement portion 40.
In FIG. 2c) the finger engagement portion 26 has been pushed further down and into the housing 4. In this position, the spring 16 will provide a force that will force the finger engagement portion 26 to be moved upwards. In this manner it is possible to shift between the “off-state” (shown in FIG. 2a) and the “on-state” (shown in FIG. 2b) simply by pushing the finger engagement portion 26.
In FIG. 2b) and FIG. 2c) the nail gripping member 28 has been completely received by the groove 32 in the housing 4. Accordingly, the battery door 6 cannot be opened. By pushing or pressing the finger engagement portion 26 the spring 16 will push the finger engagement portion 26 back to a position corresponding to the one shown in FIG. 2a).
In FIG. 2c) the head 36 of the base member 34 is arranged in the uppermost portion of the engagement portion 40.
Even though it is not shown, there may be provide any suitable type of switch (e.g. an electrical switch) configured to turn the hearing aid device 2 on or off when the finger engagement portion 26 is arranged in the configuration as illustrated in FIG. 2a), FIG. 2b) or FIG. 2c).
Thus, the finger engagement portion 26 functions as on/off button. At the same finger engagement portion 26 is adapted to be used to open the battery door 6 in order to replace the battery.
When the position of the finger engagement portion 26, and thereby the battery drawer, is changed, the head 36 of the base member 34 is moved due to the mechanical engagement between the finger engagement portion 26 and the head 36. When the position of the head 36 of the base member 34 is changed, the pin member 20 rotates about its longitudinal axis X (see FIG. 1b). Thus, the motion of the finger engagement portion 26 will cause rotation of the pin member 20 arranged in the channel 10 (see FIG. 1b).
It is important to underline that the “on-state” and the “off-state” may be chosen differently, so that the hearing aid device 2 is turned on when the finger engagement portion 26 is arranged as illustrated in FIG. 2a) and so that the hearing aid device 2 is turned off when the finger engagement portion 26 is arranged as illustrated in FIG. 2b) or in FIG. 2c).
The spring 16 may be made in any suitable material e.g. plastic or metal. The spring ensures that the correct and required force is applied to the battery drawer 24 during operation. In the “off-state”-position the hearing aid device 2 shuts down, and at the same time, a nail grip member 28 appears for easy opening of the battery door 6.
The head 36 of the base member 34 ensures that the battery drawer 24 can only move within a predefined range of motion. The range of motion of the head 36 defines or limits the range of motion of the battery drawer 24. Pushing the finger engagement portion 26 releases the battery drawer 24 from its position in the “on-state” and causes the battery drawer 24 to slide into the position of the “off-state”.
FIG. 3a) illustrates a side view of a battery drawer 24 of a hearing aid device 2. The battery drawer 24 constitutes a battery door 6 and comprises a battery compartment 12 configured to receive a cylindrical battery. The battery compartment 12 may be configured to hold a battery of the 312-type, or other types of batteries. The battery drawer 24 comprises a finger engagement portion 26 having a distal portion that constitute a nail grip member 28 protruding from a basically flat body portion 38. A bore 22 is provided in the body of the battery drawer 24. The bore 22 is intended to receive a shaft member so that the battery drawer 24 can be rotably mounted to the housing of a hearing aid device 2. The battery drawer 24 may then pivot around or at the shaft-bore interface.
Next to the battery drawer 24, a spring 16 is arranged. The spring 16 is configured to push against the battery drawer 24 to pivot or turn the battery drawer 24 in a direction away from the housing when the battery is released from the “on-state” (see FIG. 2).
An engagement portion 40 is provided in the battery drawer 24 adjacent to the body portion 28. A cam surface 42 is provided in the engagement portion 40. The mechanical engagement between the cam surface 42 and the head 36 of the base member 34 caused by movement of the finger engagement portion 26 is responsible of the motion (rotation) of the pin member 20 that takes place during operation of the finger engagement portion 26.
FIG. 3b) illustrates a perspective view of a pin member 20 and base member 34. The pin member 20 and the base member 34 constitute a one-piece body. A head 36 protrudes from the base member 34. In fact, the pin member 20, the base member 34 and the head 36 constitute a one-piece body.
FIG. 3c) illustrates a schematically perspective view of a pin member 20 and base member 34 that are mechanically engaged within the engagement portion 40 of a battery drawer 24. In FIG. 3c) the cam surface 42 is partly visible. The head 36 of the base member 34 is positioned at the cam surface 42 so that the battery drawer would be in a closed state or position. The cam surface 42 includes two turning points, at the bends at either side of the head 36, and when the head 36 is at the opposite end of the cam surface 42, the battery drawer would be in an open state or position. In use the head 36 will travel clockwise in the cam surface 42.
The battery drawer 24 comprises a finger engagement portion 26 and when mounted in a hearing aid device 2 the battery drawer 24 constitutes a battery door 6. The pin member 20 shown in FIG. 3b) is arranged in the engagement portion 40 of the battery drawer 24. It can be seen that the motion of the battery drawer 24 relative to the base member 34 will cause the movement of the base 34 and a corresponding rotation of the pin member 20.
FIG. 4 illustrates an exploded view of a hearing aid device 2. The hearing aid device 2 comprises a housing 4 and a hook 8 attached to the distal portion of the housing 4.
The hearing aid device 2 moreover comprises a battery drawer 24 configured to be received by the housing 4 of the hearing aid device 2. The battery drawer 24 comprises a battery compartment 12 that is adapted to receive and contain a battery (not shown). A bore 22 is provided in the battery drawer 24. The bore 22 is intended to receive a shaft member, so that the battery drawer 24 can be rotably mounted to the housing 4 of the hearing aid device 2.
A spring 16 is arranged next to the battery drawer 24. A pin member 20 attached to the base member 34 having a head 36 protruding from the base member is arranged next to the battery drawer 24. The battery drawer 24 comprises an engagement portion 40 configured to receive the head 36 of the base member 34.
FIG. 5 illustrates a perspective view of a hearing aid device 2. The hearing aid device 2 comprises a housing 4 and a hook 8 fixed to its distal end. An opening 46 is provided in the housing 4. A battery drawer 24 is rotably mounted to the housing 4 by means of shaft members (not shown) engaging corresponding bores 22. The battery drawer 24 constitutes a battery door 6 and is provided with a finger engagement portion 26.
It is easy to open the battery door 6 using the finger engagement portion 26, e.g. in order to replace battery or simply to turn on or off the hearing aid device 2.
