[0001] The present invention relates to a remote control device for a receiver.
[0002] As is known, many domestic appliances (such as televisions, hi-fi units, video recorders,
etc.) and some machinery for industrial use may be controlled from a distance using
suitable remote controls.
[0003] These, as disclosed by document WO 94/01844 A, normally consist of a box-shaped body
containing all of the circuitry required to generate the signals to be sent to a receiver
which converts the signals into commands. To allow a user to send different commands
to the receiver device, the box-shaped body has a plurality of keys which are connected
to the internal circuit. Therefore, by pressing different keys (even in particular
sequences), the operator can obtain the desired function from the receiver.
[0004] Most remote controls are designed to be easily transported and handled by the user
and, therefore, are small. In particular, known remote controls are made in such a
way that they can be held and operated with just one hand.
[0005] Despite all of the structural devices which have been added in order to provide a
grip which is as secure as possible, anyone in possession of a remote control doubtless
knows how often it slips from the hand and is dropped, or is accidentally bumped,
suffering irreparable damage.
[0006] In order to overcome this type of disadvantage, the prior art teaches the use of
cases made of a deformable material (normally an elastomeric material) in which the
remote control can be inserted, so as to lessen the impact suffered and, as a result,
limit any damage. An example of a hand-held electronic telecommunications device provided
with a removable protective casing is disclosed in US 5,383,091 . A first practical
disadvantage of this type of protective device is the difficulty in adapting it to
fit remote controls of different sizes. Although made of a deformable material, protective
cases do not have a sufficiently low coefficient of elasticity to provide satisfactory
adaptation characteristics, since their shape and dimensions are substantially ready-formed
and, as a result, they can only be used on a limited number of remote controls.
[0007] Moreover, covering the remote control at least partially with a container whose thickness
is certainly not negligible makes the remote control less practical to use, since
both the grip and access to the keys are obstructed.
[0008] In light of this, the aim of the present invention is to provide a remote control
device, in particular for domestic appliances, which is effectively protected from
external bumps and impact.
[0009] Another aim of the present invention is to provide a remote control device, in particular
for domestic appliances, which is practical and easy to handle.
[0010] Another aim of the present invention is to provide a remote control device, in particular
for domestic appliances, with dimensions which are substantially identical to those
of a conventional remote control.
[0011] These and other aims are substantially achieved by a remote control device for a
receiver as described in the claims herein.
[0012] Further characteristics and advantages are more clearly illustrated in the detailed
description of the remote control device in particular for domestic appliances, with
reference to the accompanying drawings, which illustrate a preferred embodiment without
limiting the scope of application, and in which:
- Figure 1 is a perspective view of a device made in accordance with the present invention;
- Figure 2 is an exploded view of the device illustrated in Figure 1;
- Figure 3 is a side view of the device illustrated in Figure 1, according to the arrow
F in Figure 1;
- Figure 4 is a side view of the device illustrated in Figure 1, according to the arrow
G in Figure 1.
[0013] The remote control device according to the present invention is labelled 1 as a whole
in the accompanying drawings.
[0014] The device 1 comprises a case body 2, which is substantially box-shaped (illustrated
in Figure 2), on which a closing plate 5 is securely fixed.
[0015] In particular with reference to Figure 2, the case body 2 has an internal surface
3 which forms a housing 8. Inside said housing 8 there are electronic control means
7, whose function is to generate electromagnetic control signals with which the user
can operate a receiver.
[0016] To protect at least the case body 2 and the circuitry contained inside it from bumps
and dropping, there is a cover element 6 fixed to an outer surface 4 of the case body
2 in such a way that it cannot be removed.
[0017] The cover element 6 is a sheath made of an elastomeric material which surrounds the
case body 2.
[0018] Moreover, in the outer surface 4 of the case body 2 there is a cavity 9 in which
a power unit 10 (basically, the batteries) is inserted, to allow operation of the
electronic control means 7.
[0019] At the cavity 9, the cover element 6 has a through-hole 11, allowing the user access
to the power unit 10 so that, for example, it may be substituted when low.
[0020] In order to effectively protect the power unit 10 as well, the device 1 has a sealing
cover 12 which normally seals the above-mentioned through-hole 11, and which is fixed
close to the hole 11.
[0021] The sealing cover 12 may be removed, allowing access to the power unit 10 if necessary.
[0022] In order to make the device 1 practical and easy to handle, as well as giving it
an attractive appearance, the sealing cover 12 is made in such a way that its shape
substantially matches that of the through-hole 11 in the cover element 6.
[0023] The sealing cover 12 (as is schematically illustrated in Figure 2) normally consists
of a single rigid surface 13.
[0024] Alternatively, this sealing cover may comprise a first layer 13 made of a rigid material,
and a second layer 14 (illustrated with a dashed line), fixed to the first layer 13
and made of an elastomeric material.
[0025] In this alternative embodiment, when the sealing cover 12 is fixed to the rest of
the device 1, at the through-hole 11, the first layer 13 is opposite the power unit
10, whilst the second layer 14 may be an extension of the cover element 6, forming
a single, substantially continuous surface with the above-mentioned cover element
6.
[0026] Advantageously, the cavity 9 is made in the outer surface 4 in such a way that the
power unit 10 is distanced from the surface on which the device 1 rests. This feature
allows improved isolation of the power unit 10 from humidity and, in general, from
harmful substances with which the cover element 6 may come into contact.
[0027] The case body 2 and cover element 6 have an elongated shape and extend substantially
in a direction defined by a longitudinal axis (not illustrated) of the case body 2.
Moreover, to improve both the user's grip and the natural barycentre, the cover element
6 has a curved configuration 6a on the side opposite the case body 2 (see Figure 4).
[0028] Despite this particular shape, a suitable distribution of the weights of the various
parts of the device 1 means that, when the device 1 is placed on a surface in such
a way that it rests on the cover element 6, it maintains a substantially stable, balanced
position.
[0029] The cover element 6 also has a plurality of mouldings 15 (see Figure 3) which extend
transversally relative to the longitudinal axis of the case body 2, and of which at
least three, labelled 15a, 15b and 15c, are contact zones for resting the device 1
on a fixed surface PF.
[0030] In particular, two of these mouldings, 15a and 15b, are located at the ends of the
cover element 6, whilst the third is substantially at the centre of the cover element
6.
[0031] In addition, the sealing cover 12 of the through-hole 11 in the cover element 6 has
a convex shape such that the through-hole remains clear of the fixed surface PF. This
protects the electrical contacts from any liquids or other elements present on the
fixed surface PF, which might damage the circuits in the device 1.
[0032] The control means 7 basically consist of an electronic circuit 16 and a plurality
of elements 17 for operation of the electronic circuit 16.
[0033] The electronic circuit 16 is positioned inside the housing 8, formed by the inner
surface 3 of the case body 2 and is designed to generate electromagnetic signals to
be sent to the receiver (for example, a television).
[0034] The operating elements 17 are normally keys positioned in a plurality of through-holes
18 made in the closing plate 5. In this way, the keys may be reached by the user who,
pressing them, can select which control signals should be transmitted to the receiver.
[0035] In order to make the device 1 even more safe and strong, in an alternative embodiment
illustrated in Figures 3 and 4, the cover element 6 has at least one extending portion
19, extending transversally to the longitudinal axis of the case body 2, that is to
say, parallel with the mouldings 15. The function of said portion 19, which partially
covers the closing plate 5, is to prevent any damage to the device 1 if the device
1 is dropped or bumped on the closing plate 5.
[0036] The present invention has important advantages.
[0037] Firstly, a remote control device for a receiver which is made in accordance with
the present invention is extremely practical and easy to handle, since the addition
of the protective material does not change its dimensions relative to those of a conventional
remote control and does not obstruct user access to the keypad.
[0038] Another advantage lies in the fact that, thanks to suitable shaping of the profile
of the transversal mouldings in the deformable material, it is easier for the user
to grip and much more secure than a conventional remote control, with reduced risks
even for the internal circuits. The risk of dropping the remote control, with consequent
malfunctions, is therefore much reduced.
[0039] It is also important to emphasise that, even from an economic viewpoint, the remote
control device according to the present invention is extremely advantageous since,
with a protective structure like the one described above, the product obtained is
substantially the same price as a conventional remote control, but has the added advantage
of being shock resistant to bumps and less easy to drop.
[0040] A further advantage emerges by observing that a careful distribution of the weights
and shape of the various parts of the device allows the device to remain in a stable,
balanced position when placed with the keys uppermost, despite the fact that the deformable
portion has a curved configuration in the area rested on the surface.
[0041] The invention described can be subject to numerous modifications and variations without
thereby departing from the scope of protection, as defined by the claims. Moreover,
all the details of the invention may be substituted by technically equivalent elements.
