[0001] The subject of the present utility model is a control panel for the automatic and
manual actuation of a window winder, particularly designed to be mounted on motor
vehicles.
[0002] As is known, in motor vehicles which have an electric window winder for the side
windows, there is currently provided a control panel having a push button for raising
and a push button for lowering each window.
[0003] With control panels of the known type the displacement of the windows is only effected
by maintaining the corresponding push button depressed, with the necessity therefore
of actuating the push button itself for several seconds in such a way as to obtain
complete lowering or raising of the window.
[0004] This type of arrangement is particularly inconvenient, above all, for the driver,
who, even if for only a short time, must take his attention away from the driving
operations, with the possible associated problems. Another problem which occurs in
control panels of the known type is constituted by the fact that these latter have
a rather complex and consequently expensive structure.
[0005] The object of the present invention is that of solving the above explained problems
by providing a control panel for automatic and manual actuation of window winders,
suitably designed for motor vehicles, which will give the possibility of manual actuation,
understood as displacement of the window for as long as the corresponding push button
is actuated, and automatic actuation, understood as a single actuation which triggers
an electro magnet or other electrically equivalent component to obtain complete raising
or lowering of the window without the necessity of continuing to actuate the corresponding
push button.
[0006] Within the ambit of the above explained object, a particular object of the invention
is that of providing a control panel which will give the possibility of having a single
push button which allows both the manual actuation and the automatic actuation uniquely
independent on the different pressure which is exerted thereon.
[0007] The present control panel for the control of the window winder is structured in such
a way as to have a simplified assembly and to offer the widest guarantees of reliability
and safety in use.
[0008] The present control panel for window winder control with manual and automatic actuation
is easily obtainable starting from commonly available materials and, moreover, has
a very contained cost.
[0009] The above explained objects, as well as the objects listed and others which will
become more clearly apparent hereinbelow, are achieved according to the invention
by a control panel for automatic and manual actuation of window winders, particularly
for motor vehicles, characterised by the fact that it comprises a box-like body closed
below by a rigid printed circuit and supporting at least one push button for actuating
a manual movable contact and an automatic movable contact, the said push button being
slidable against the action of a first elastic element to carry the said manual movable
contact into contact with the printed circuit and against the action of a second elastic
element, with a greater elastic constant than this first elastic element, to carry
the automatic movable contact into contact with the printed circuit.
[0010] Further characteristics and advantages of the subject of the present utility model
will become more clearly apparent from a study of the description of a preferred,
but not exclusive embodiment of a control panel for the automatic and manual actuation
of the window winder control, particularly for motor vehicles illustrated by way of
indicative, but non-limitative example with the aid of the attached drawings, in which:
Figure 1 schematically shows the control panel according to the invention in perspective
view;
Figure 2 shows the control panel seen in plan;
Figure 3 illustrates the control panel sectioned along the line III-III of Figure
2;
Figure 4 represents the control panel in section, with the manual movable contact
suitably sectioned.
[0011] With reference to the numerical symbols of the said Figures, the control panel for
the automatic and manual actuation of the window winder control, particularly designed
for motor vehicles, which is indicated generally with the reference numeral 1, comprises
an outer box-like casing 2 which can have any suitable shape.
[0012] The box-like casing 2 is closed below by a rigid printed circuit 3 which is fixed
to the box-like body by means of bolts 4 and has its contacts on the inwardly directed
face.
[0013] Push buttons, generally indicated 5, project from the upper face of the box-like
casing 2 and, in the illustrated embodiment, are constituted by the passenger side
raising push button and the passenger side lowering push button.
[0014] The push buttons 5, which preferably have a shaped body with a perimetral flange
6 which engages the inner face of the box-like body 2, are connected to a shaped inner
body 7 which, as will be explained more clearly hereinbelow, effects the actuation
of the contacts.
[0015] In the illustrated example the driver side push buttons are both of automatic actuation,
whilst the passenger side push buttons are of manual actuation.
[0016] Obviously, there is no conceptual change if all the push buttons have the possibility
of automatic actuation.
[0017] The automatic actuation push button has a manual movable contact 10 which is supported
by a resilient rubber diaphragm 11 which, in the region which supports the contact
10, defines a bell-shape part 12 which overlies the printed circuit 3.
[0018] The movable contact 10 is advantageously made of conductive rubber or other similar
material.
[0019] There is also provided, again supported by the rubber diaphragm 11, an automatic
movable contact indicated 20 advantageously disposed spaced from the manual movable
contact 10.
[0020] The shaped body 7 is connected to the diaphragm 11, preferably in the support region
of the manual movable contact 10, by means of a second resilient element which can
be constituted by a spring 30 or other equivalent resilient means which has the peculiarity
of having a greater elastic constant than the first resilient means, constituted by
the diaphragm 11, in its cup-shape portion 12.
[0021] The shaped body 7 further has a pressing projection 31 which is disposed over the
automatic movable contact 20.
[0022] The manual contact 10 has the property of effecting the actuation of the window,
to raise or lower it, for the whole of the time period for which the movable manual
contact 10 is in contact with the printed circuit 3, whilst the automatic contact
20 functions to actuate an electro magnet or other corresponding electrical component,
which activates the electrical supply circuit of the motor for the actuation of the
window winder during the whole of the period of time necessary to effect the complete
raising or lowering movement.
[0023] In the illustrated example, adjacent the automatic actuation push button 5 there
is provided a manual actuation push button 5 which is conceptually analogous, with
the single difference that the key has an inner body 7a which acts directly on the
cup-shape part 12 ` carrying the associated movable manual contact 10.
[0024] For completeness of the description it is appropriate to emphasise that the shaped
body 7 has a projecting tooth 40 which engages with a resilient reinforcing tongue
41.
[0025] This latter serves to make the passage from the actuation of the manual contact to
actuation of the automatic contact sensitive to the touch.
[0026] In practice, by exercising a moderate pressure on the push button 5 the resilient
bias exerted by the cup-shape part 12 is overcome, as illustrated in Figure 4, and
the movable manual contact 10 is carried into contact with the printed circuit 3,
causing actuation of the window for the whole of the time in which the pressure is
exerted.
[0027] At this stage, the tooth 40 comes into contact with the resilient reinforcing tongue
therefore making the pressure to be exerted perceptible to the touch of the utiliser.
[0028] By exerting a further pressure there is caused the compression of the second resilient
element 30 with consequent actuation of the movable automatic contact 20 by the projection
31, by a further downward displacement of the push button 5.
[0029] In these conditions, the window is moved to the end of its path without the necessity
of exerting further pressure on the push button.
[0030] From what has been described hereinabove, it will be - seen how the invention achieves
the proposed objects.
[0031] In particular, with an extremly simple structure there is provided a control panel
which allows manual or automatic actuation to be effected in dependence on the pressure
which is exerted by utilising the presence of two resilient elements having a different
elastic constant from one another in such a way as to obtain two different movements
for the push button with, consequently, two different actuations.
[0032] Further, another important aspect of the invention is constituted by the fact that
the presence of the resilient diaphragm over the printed circuit protects it from
contact with the external environment, thereby avoiding the infiltration of dust or
other elements which could damage and modify the precise action of the contacts.
[0033] The invention, thus conceived, is capable of numerous modifications and variations,
all lying within the ambit of the inventive concept.
[0034] Moreover, all the constructional details can be replaced by other, technically equivalent
elements.
[0035] In practice, any materials may be used, and likewise, any dimensions and contingent
forms according to requirements, as long as they are compatible with the specific
use.
