Description
TECHNICAL FIELD
The present invention relates generally to a detachable face plate for use with automotive electronic components and more particularly to a detachable face plate with improved functionality.
BACKGROUND ART
Modern automotive electronic components have increased sophistication and cost. The loss of such components due to theft is an ongoing concern for both consumers and automotive component designers. Theft of accessories such as stereo components, remote communication components, and a variety of other electronic components has prompted design changes to such components in order to incorporate anti-theft systems.
One known anti-theft system is the use of detachable face plates on electronic components. Detachable face plates allow the consumer to remove the control portion of a component (commonly an automotive stereo systems) without removing the entire component. This provides anti-theft protection in several ways. The removal of the face plate gives the appearance to potential criminals that the component is not present in the automobile. In addition, theft of the component without the detachable face plate often renders the component worthless.
Although the use of a detachable face plate is known to provide valuable anti-theft properties to electronic components, it can also create disadvantages. One known disadvantage involves the removal of the face plate from the electronic component. Often, detachable face plates are detached from their underlying components through the use of an eject button. Without special design considerations, however, the face plate can often fall away from the underlying component during the removal process. This can have the undesired effect of requiring the use of two hands to remove the face plate. Often the tendency to fall away from the main component can be further exacerbated if the vehicle is positioned on an incline.
Often, in order to prevent the face plate from falling off the component during the removal process, the component is designed with multiple-piece retaining mechanisms. These mechanisms are undesirable since they can increase the cost of the electronic component. In addition, the design of multi-piece retaining mechanisms can increase the incidents of failure for the electronic component. This can have the undesirable characteristic of increasing repair costs and decreasing customer satisfaction.
It would therefore be highly desirable to have a detachable face plate that would prevent the face plate from falling away from the component during removal, would allow for one hand operation during removal, would not result in increased construction or warranty costs, and would operate even while the vehicle is on an incline.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an automotive electronic component with a detachable face plate with improved functionality.
It is a further object of the present invention to provide an automotive electronic component with a detachable face plate that allows for one hand operation without increased construction or warranty costs.
In accordance with the objects of this invention, an automotive electronic component with a detachable face plate is provided. The automotive electronic component includes a base component. The automotive electronic component further includes a face plate which is detachable from the base component. A cantilever element is positioned on either the base component or the face plate. A rib element is positioned on the other of the base component or the face plate. During removal of the face plate from the base component, the rib element engages the cantilever element and prevents the complete disengagement of the face plate from the base component until an additional force is applied to the face plate. This allows one handed removal of the face plate from the base component.
Other objects and features of the present invention will become apparent when viewed in light of the detailed description of the preferred embodiment when taken in conjunction with the attached drawings and appended claims.
BRIEF DESCRIPTION OF DRAWINGS
FIG. 1
is an illustration of an automotive electronic component in accordance with the present invention;
FIG. 2
is a cross-sectional illustration of an automotive electronic component as shown in
FIG. 1
; and
FIG. 3
is a cross-sectional illustration of an automotive electronic component as shown in
FIG. 1
illustrating the partial disengagement of the face plate from the base component.
DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
Referring now to
FIG. 1
, which is an illustration of an automotive electronic component
10
in accordance with the present invention. The automotive electronic component
10
is illustrated as an automotive stereo system. In alternate embodiments, however, the automotive electronic component
10
can be a wide variety of automotive electronic components including, but not limited to, automotive communication packages such as On-star, global positioning systems, or automotive information systems.
The automotive electronic component
10
includes a base component
12
and a face plate
14
. The face plate
14
is detachable from the base component
12
to provide anti-theft protection for the automotive electronic component
10
. In one embodiment, the base component
12
contains the majority of the functional circuitry for the automotive electronic component
10
, while the face plate
14
contains the display
13
and controls
15
. In alternate embodiments, however, the circuitry and controls may be distributed between the two elements in a variety of fashions. The use of such detachable face plates
14
and base components
12
are well known in the art.
Referring now to FIG.
2
. The automotive electronic component
10
further includes a cantilever element
16
and a rib element
18
. In one embodiment, the cantilever element
16
is positioned on the base component
12
and the rib element
18
is positioned on the face plate
14
. In alternate embodiments, however, the cantilever element
16
can be positioned on the face plate
14
and then the rib element
18
will be respectively positioned on the base component
12
. The rib element
18
and the cantilever element
16
can be molded directly into the face plate
14
and the base component
12
, respectively, to further reduce manufacturing cost and complexity. The cantilever element
16
and the rib element
18
are positioned such that when the consumer initiates the removal of the face plate
14
from the base component
12
, the rib element
18
engages the cantilever element
16
and prevents complete detachment of the face plate
14
from the base component
12
until an additional force is applied to the face plate
12
(see FIG.
3
). Although the rib element
18
and the cantilever element
16
are illustrated in a particular shape, it should be understood that a wide variety of shapes are contemplated.
In this fashion, the consumer can activate any of a variety of releasing mechanisms (not shown) well known in the prior art, and yet the face plate
14
will not completely disengage from the base component
12
until an additional force is applied. This facilitates one hand operation by the consumer. Furthermore, the present invention will function even when the automobile is positioned at a variety of angles, such as on a sharp incline. In addition, the use of the cantilever element
