[0001] The present invention relates to an alarm clock and a time warning device associated
thereto.
[0002] A large number of different kinds of alarm clocks is on the market, all having the
common feature of using a sound-signal emission for waking up the user from sleep.
Unfortunately, and with all the negative consequences one can easily guess, it frequently
can happen that the sound doesn't succeed in waking up the user, owing to the fact
that he has got accustomed to the sound emitted by the alarm clock, or that the clock
is not positioned in close proximity to the bed and so the sound reaches the user's
ear with softened intensity.
[0003] Furthermore, it has to be pointed out that the problem often occurs of two or more
people asleep in the same room, having to wake up at different times in the morning.
In this case the sound of the alarm programmed by the user which has to wake up earlier
disturbs the other person's (or persons') sleep, sometimes to the point that a both
sudden and undesired awakening can not be avoided.
[0004] It is an object of the present invention to solve the above mentioned problems, providing
an alarm clock which reduces a lot the risk of not effectively and reliably accomplishing
to his function with respect to known alarm clocks, and succeeds in carrying out said
function towards only one user in a personalised manner, without disturbing other
people asleep in the same room.
[0005] This object has been achieved with the vibrating device alarm clock according to
the present invention, which comprises a driving assembly and a remote vibrating device.
The, driving assembly comprises a clock and a driving signal transmitter timed by
the clock. The vibrating device, placeable in a portion of the bed to wake up a sleeping
person by means of its vibration, comprises a receiving element responsive to the
driving signal, at least one vibrating element electrically connected to the receiving
element and operated thereby in response to the driving signal, and electric feed
means, preferably of a battery type, electrically connected to the at least one vibrating
element and to the receiving element.
[0006] Other features and advantages of the vibrating device alarm clock according to the
present invention will be apparent from the following description of a preferred embodiment,
made purely as an example and implying no limitation, with reference to the accompanying
drawings, in which:
- Figure 1 shows a perspective view of the vibrating device of the alarm clock according
to the present invention;
- Figure 2 shows an exploded perspective view of a vibrating element of the device of
figure 1;
- Figure 3 shows an exploded perspective view of a battery-housing case of the vibrating
element of figure 1.
[0007] With reference to the above figures, the alarm clock according to the present invention
comprises a driving assembly, not shown, with a conventional clock which, when a sharp
time is struck, programmed by the user with a programming procedure that is fully
conventional as well, operates a radio signal transmitter for driving a vibrating
device 1, placed in a remote position.
[0008] The vibrating device, to be placed through a slot suitably formed in the lining inside
a pillow on which the user lays his head while resting, comprises a laminate bar 2,
a little shorter with respect to the length of the pillow. A receiving element 3,
schematically shown in figure 1, responsive to the signal emitted by the driving assembly,
is connected to bar 2 in a central position. Element 3 is provided with a wire antenna,
not shown, placed along bar 2 according to an annular path.
[0009] A vibrating element 4, electrically connected with receiving element 3 by means of
wires, not shown, is fixed to each end of bar 2 and is operated by element 3 in response
to the driving signal.
[0010] With reference in particular to figure 2, in the depicted embodiment each vibrating
element 4 comprises a cylindrical container 5, connected along a directrix with the
respective end of bar 2. Inside container 5 a motor 9 is placed, operating a rotor
6, pivotally supported coaxially to container 5, having a substantially cylindrical
shape but with an incomplete development due to the provision of a plane longitudinal
milling 6a. Rotor 6 is unbalanced owing to milling 6a, so that it generates, when
operated, a vibration which is transmitted via case 5 along laminate bar 2 to device
1 on its whole.
[0011] Battery-housing cases 7, shown in particular in figure 3, are placed near each vibrating
element 4 and house batteries 10 electrically connected to receiving element 3 and
to vibrating elements 4 for their feed. In the depicted embodiment two cases 7 for
each bar end are provided, and they have a cylindrical shape too, being closed by
a respective screw plug 8. Batteries 10 are typically 1.5 Volt ones and advantageously
can be of a rechargeable kind.
[0012] As above said, when the programmed time is struck the driving assembly emits the
signal which is picked up by receiving element 3 and transmitted by it to vibrating
elements 4, triggering off the vibration of device 1. In this way the user, sleeping
with his head on the pillow and so directly contacting the device, wakes up as a consequence
of the vibration.
[0013] The above described embodiment of vibrating device 1, with vibrating element 4 symmetrically
placed at the ends of bar 2, allows an optimal involvement of the pillow, providing
a vibration which is strong enough to wake up the user, whichever part of the pillow
he may be laying his head upon.
[0014] The two elements 4 can be operated simultaneously or alternatively. The second choice
is particularly advantageous to reduce the electric consumption of the device.
[0015] The vibration strength is adjusted by the user acting on the driving assembly, as
a function of his needs and characteristics. In fact, the possibility of increasing
or reducing the rotation speed of rotor 6 is provided, modifying with a simple adjustment
operation the features of the signal emitted by the driving assembly, thus producing
a vibration respectively stronger or weaker.
[0016] The vibration of device 1 can be produced by means of other equivalent systems, as
for example using cam strikers, vibrating plates and so on. Even if according to what
above described the signal emitted by the driving assembly is advantageously a radio
signal, a wire connection can be provided between the driving assembly and the vibrating
device for the direct transmission of an electric signal.
[0017] The material which laminate bar 2 is made of must have both a certain stiffness and
a suitable capability of transmitting vibrations. A material which is particularly
suitable to the purpose is PVC, namely in its form known under the FOREX™ trade mark.
[0018] Though the most advantageous placing of the vibrating device is, as above said, inside
the pillow, it is possible to provide, if preferred by the user, different placings,
e.g. in internal pockets suitably formed in the mattress.
[0019] It will be apparent from the above that the alarm clock according to the present
invention accomplishes his function in a certain and reliable manner. Furthermore,
its function is addressed only to the person who actually has to be woken up, without
disturbing other people asleep in the same room or even in the same bed.
