OBJECT OF THE INVENTION
[0001] The present invention refers to an improved mobile device for a cradle which takes
profit of the recent developments in electroluminescence to obtain a mobile device
more durable and practical in its use.
BACKGROUND TO THE INVENTION
[0002] Mobile devices for cradles are already known since a certain time, being aimed at
stimulating the cognitive development of babies. Basically, the mobile devices for
cradles known so far are formed by a projector which casts varying images on the roof
of the room in which the baby is kept or alternatively, on a screen forming part of
the mechanism of the mobile device. Some mobile devices are known which may have a
structure from which various plastic or woven material figures hang down, which movement
is aimed at amusing the baby apart from generating varying shadows thanks to the projector.
Apart from the visual stimulation, many mobile devices currently known comprise a
device emitting melodies adapted to the projected images.
[0003] However, these mobile devices still have some drawbacks due to the great number of
moving parts which are necessary for its manufacture, as for example the plastic or
woven material figures representing small horses, different types of fish, stars,
etc. to be projected onto the roof, the parts which constitute the projector itself
and the parts of the mechanism to move the projector or said figures. This high amount
of components is not only the reason for the undesirable frequency of disturbances
in the current mobile devices for cradles but they also are the reason for additional
hindrances during the transport, assembly and disassembly of said mobile devices.
[0004] As a consequence, there is still the need of a mobile device for a cradle which solves
the above stated drawbacks.
DESCRIPTION OF THE INVENTION
[0005] The present invention solves the above stated problems thanks to a new improved mobile
device for a cradle using electroluminescent devices such as LEDs, OLEDs, AMOLEDs
and/or electroluminescent printing (to be named "electroluminescent devices" in the
following) assembled on a cover portion which is installed above the cradle to form
illuminated figures to improve the cognitive development of the baby. The electroluminescent
devices are connected to a small processing means which will contain multiple illumination
programmes. This configuration of the mobile device for a cradle completely prevents
the use of mobile parts, which means a longer service life and permits a much faster
manufacture.
[0006] Accordingly, the mobile device of the invention has a cover connected to support
means adapted to hold said cover above a baby laying on the cradle. The cover has
incorporated a plurality of electroluminescent devices implemented on a thin film.
These electroluminescent devices form different figures on the cover as for example,
figures representing horses, different type of fish, stars and in general any figure
of an object or animal which might be enjoyable and/or illustrative for a baby. In
its turn, the electroluminescent devices are connected to a driving unit which permits
to illuminate the figures they make up with different colours according to preestablished
illumination programmes. Preferably, the mobile device for a cradle according to the
invention comprises as well an on/off switch.
[0007] Thus, for example in the case that the electroluminescent devices form figures corresponding
to different kinds of fish and corals, different fish forms could be illuminated alternatively
with different colours, creating an impression of movement or bringing about blinking
effects, variations in the intensity, etc. Alternatively, if the scene is formed by
the moon and the stars, adequately programming the electroluminescent devices it would
be possible to obtain that the moon may represent its different phases and that the
stars show intermittent flickering.
[0008] Any expert in the matter will easily imagine other examples of scenes for children
which could be shown in movement using the electroluminescent devices fully integrated
on the cover and therefore will not be described in more detail.
[0009] Additionally, it is possible to add to the mobile device of the invention some plastic
or woven material figures hanging from the cover, which will have some natural movement
due to the displacement of the cradle and to the action of air, thus completing the
effects created by the figures formed by the electroluminescent devices.
[0010] According to a preferred embodiment of the invention, the mobile device comprises
as well sound reproduction means connected to the processing means, including optionally
a MP3 device. Thus, different melodies or tunes could be reproduced as well as any
other accompanying sound in function of the combination of colours obtained by the
electroluminescent devices.
[0011] On the other hand, it will be understood that the processing means could be implemented
by any element capable of controlling the electroluminescent devices and eventually
the sound reproduction means. However, it is preferable that the processing means
be selected among: a microcontroller, a microprocessor, a CPU, a DSP, a FPGA or an
ASIC.
[0012] On the other hand, the support means holding the cover above the baby in the cradle
may adopt different executions although in this description two particular embodiments
will be described.
[0013] In a first preferred embodiment of the support means, these comprise at least a clamping
mechanism arranged to engage the bars of a side of the cradle. The clamping mechanism
could be formed, as will be shown in more detail later on, by a couple of parallel
plates which are capable of getting close or separating from each other by driving
a winged nut or wheel, having adequate dimensions for engaging two consecutive bars
of one of the side of the cradle. It will be sufficient in this situation to arrange
the clamping mechanism between two of the bars, pressing both plates until these will
be firmly seated on said bars. Although it could be sufficient with only one clamping
mechanism, in a preferred embodiment of the invention two clamping mechanisms will
be used for its engagement to the bars of two opposed sides of the cradle thus obtaining
a higher stability.
[0014] In a second preferred embodiment of the support means, these will comprise a curved
tube contained in a plane which is substantially parallel to the cover that, when
sitting on an horizontal surface, permits to hold said cover above the head of a baby.
In this second embodiment of the support means, these do not engage the cradle but
they engage the curved tube to support the cover above the head of the baby, to permit
its use out of the cradle. This permits furthermore to use the mobile device of the
invention out of the cradle, for instance, in the case that the baby is laying on
a carpet or fitted carpet.

PREFERRED EMBODIMENT OF THE INVENTION
[0016] An example of the invention in connection with the annexed drawings will be explained
in the following. Particularly, figures 1 a and 1b show respective examples of mobile
devices (1) for a cradle according to the invention in which the support means (3,
3') are respectively formed by two clamping means (3) and one unique clamping means
(3). It is to be seen from both figures that the mobile device (1) is comprised of
a cover web (2) supported by clamping means (3). The cover (2) has integrated a plurality
of electroluminescent devices such as LEDs, OLEDs, AMOLEDs and/or electroluminescent
printings (not individually shown in the drawings) forming infantile figures (4) consisting
in fish representations in the example of figure 1a and stars in the example of figure
1 b. The example of figure 1b has as well a set of figures (6) hanging from the cover
(2) consisting in stars in this particular case.
[0017] Figures 1 a and 1 b show as well the processing means (5) which in this examples
is incorporated with the sound reproduction means and the clamping mechanisms (3),
both being located in an internal side when the mobile devices (1) are secured to
a cradle (1) as shown in figures 2a and 2b. Optionally, there is the possibility to
incorporate a MP3 device to broaden the selection of melodies.
[0018] Figure 3 shows in a greater detail a clamping means (3) as those used in the mobile
devices (1) of figures 1 a and 1 b. In this case, it may be observed that each clamping
means (3) is formed by one pair of parallel plates (3b) which are capable of getting
closer to one another or of being separated by the use of a winged nut (3a). Thus,
to secure a mobile device (1) of the invention to a cradle (100), it will be sufficient
to locate the one or various clamping means (3) between two consecutive bars of a
cradle, rotating the winged nut (3a) until the plates (3b) are well seated against
said bars. As mentioned above, the sound reproduction means, integrated in this case
in the processing means (5), are located on an internal side of the cradle (100) in
order that the baby may be capable to listen to the tunes without need to use an excessively
high volume of reproduction.
[0019] At last, figure 4 shows another example of the mobile device (1) according to the
invention in which the support means (3, 3') are formed by a bar (3') curved to adopt
a U form, contained in a plane substantially parallel to cover (2). It is to be clearly
appreciated that said mobile device (1) could be used to entertain a baby laying on
a carpet or similar as it is not required anything else but an horizontal surface
to be placed on.
