Description

CONTAINER FOR HANDLED DEVICE FOR REMOTE CONTROL AND RELATED KIT AND DEVICES.

TECHNICAL SCOPE OF THE INVENTION

The present invention pertains to the technical field of the production of control devices for the remote control of apparatuses.

In particular, this invention relates to the construction of a case for control devices used for the remote opening and/or closing of doors and gates and a mounting kit for said case.

The present invention also relates to a control device comprising said casing and a mounting kit for said device.

DESCRIPTION OF THE STATE OF THE ART

According to the prior art, control devices for the remote control of apparatuses, commonly known as remote controls, essentially consist of an electronic device that makes it possible to send signals to another device located at a distance, also known as remote-controlled device.

Control devices have different fields of application, such as their use to open and close doors and gates, at home to control television equipment or hi-fi systems, or even for the control of split air conditioning systems, lighting, control of the rolling/unrolling of awnings, the opening/closing of motor vehicles, etc.

The control device is able to generate the appropriate coded electromagnetic signals, normally signals modulated at a particular frequency selected within a predetermined range.

The control device is normally pocket-size, that is, a size which allows it to be easily transported.

The size of the control device essentially depends on the number of buttons it has.

Depending on the type of remote-controlled device, in fact, the control device is normally equipped with one or more buttons that when activated send different coded signals, which correspond to different and specific actions, such as in the case of an automatic gate, where a first button is used to open the gate and a second button is used to close it.

Most of the control devices to achieve this transmission use lighted diodes, or LEDs, which emit signals in the form of infrared light at a predetermined wavelength. In other cases, radio waves are used instead, in which case they are commonly called radio remote controls. The construction of the control devices of the known type normally involves the use of a container comprising a casing made up of two plastic half-shells able to be connected to each other by means of screws or a snap-lock, inside which a circuit board to generate the aforementioned coded signals is placed. Electronic devices are properly powered by means of one or more batteries also housed inside the casing.

The circuit board has one or more electrical switches, or micro-switches, that are activated by special actuator elements or buttons. On one side said buttons are placed in contact with these switches and on the other they are placed in suitable openings in the casing, thus protruding towards the inside so as to be easily operated by the fingers of the user.

The buttons are kept in place in their respective openings of the casing, within which they can move in the required stroke range to activate the electrical switches with which they interact.

A drawback posed by the control devices of the known type is the laboriousness of maintenance interventions, especially when it is necessary to replace the battery. In fact, the case must be opened to remove the discharged battery and replace it with a new one. During said operations, and during the opening of the case, the buttons can come out of their respective housings provided in the case and fall, with the risk of their possible loss. In addition, the subsequent closing phase of the case performed by coupling the two halves requires the repositioning of the buttons inside their respective housings and keeping them in place during the process. This operation is very laborious, especially when there are multiple buttons.

Another drawback posed by the control devices of the known type lies in their reduced versatility. In fact, a control device is associated with a pre-established remote-controlled device and each key is associated with a predefined function. When it is necessary to change this configuration, that is, if the user wishes to associate additional remote-controlled devices with the same control device or to have more buttons with different functions, it is necessary to use additional or new control devices with a suitable number of buttons to perform all functions. The main object of the present invention is therefore to resolve such problems. In particular, one object of the present invention is to provide a control device for the remote control of apparatuses in which maintenance and installation operations are simplified. Another object of the invention is to provide a control device for the remote control of apparatuses that is easily adaptable to configurations that are different from the basic configuration, with no need to replace it completely.

Another object of the invention is to provide a control device for the remote control of apparatuses that has lower production costs than the known control devices.

SUMMARY OF THE INVENTION

The present invention is based on the general consideration that it is possible to simplify the maintenance operations of a control device for the remote control of apparatuses by arranging the actuator elements outside the casing of the device and keeping them in position through a cover which can be externally connected to the casing.

According to another embodiment, the present invention relates to a pocket-sized device comprising means for generating control signals to control a remote apparatus that are housed in a case constructed as indicated above.

Advantageously, the opening and closing of the casing for maintenance and installation of the pocket-sized device are simplified.

The means for generating control signals preferably comprise at least one switch that can be operated by said at least one actuator element.

The device preferably comprises at least one light emitting element and at least one diffuser element for the light emitted by said light emitting element.

The operation of the switch by means of the actuator element is visually perceived through the light emitted by said light emitting element, light that is advantageously diffused by the diffuser element.

The device is preferably a control device for opening and closing gates.

According to a further embodiment, the present invention relates to a mounting kit of a pocket-sized case comprising a casing suited to house means for generating control signals to control a remote apparatus, said case comprising at least one actuator element the operation of which is suited to have effect on said control signal generating means, said kit comprising two or more cover elements that can be externally connected to said casing and wherein the actuator element is placed between said casing and one of said cover elements when connected to said casing.

DETAILED DESCRIPTION OF THE INVENTION

Although the present invention is described below with reference to embodiments represented in the drawings, the present invention is not limited to the embodiments described below and shown in the drawings. On the contrary, the embodiments described and represented herein clarify some aspects of the present invention, the scope of which is defined in the claims.

The present invention has proved particularly advantageous when applied to control devices for the remote-controlled opening and closing of electrical gates. It should, however, be pointed out that the present invention is not limited to control devices for the remote-controlled opening and closing of electrical gates. On the contrary, the present invention can be conveniently applied to all control devices for remote control equipped with buttons for sending control signals to remote devices suited to be remotely controlled, such as, for example, televisions or hi-fi apparatuses, split air conditioning systems, automated awnings and blinds, cars, etc.

With reference to Figures 1 to 7, a control device 1 is described according to a first preferred embodiment of the invention.

The control device 1, hereinafter referred to as control for simplicity, is in particular a control for opening and closing an electric gate, the latter not shown in the figures, which will be equipped with an appropriate device suited to receive the signals emitted by the control 1.

The control 1 is equipped, in this regard, with two buttons 2 and 3, button 2 suited to be operated to send a signal for opening the gate and button 3 suited to be operated to send a signal for closing the gate.

The control 1 comprises a case 40 consisting of a casing 4 made up of a first half- shell 5 and a second half-shell 6 that can be connected to each other by means of a fixing screw 7. The head 7a of the fixing screw 7a is housed in a special housing 8 made in the first half-shell 5 and engages in a threaded hole 9 obtained in a cylindrical element 10 of the second half-shell 6, as shown in Figure 5.

In variant embodiments, the union of the first half-shell 5 to the second half-shell 6 can be achieved with different fixing means, such as suitable elastic fins made in one of the two half-shells that snap into special seats provided in the other half-shell.

Between the first half-shell 5 and the second half-shell 6 there is a circuit board 12 supporting the electronic components 13 for the management and generation of coded signals to control the gate, in particular the two opening and closing signals.

For this purpose, and in a position aligned with the aforementioned activation buttons 2 and 3, there are two microswitches 14 and 15 on the circuit board 12. The closure of said two microswitches 14 and 15, through the operation of the two respective buttons 2 and 3, is detected by the electronic components 13, which provide for the generation of a corresponding modulated signal sent by an emission device comprising, for example, an antenna. On the circuit board 12 there is also a LED light 16.

Therefore, when the modulated opening or closing signal is sent out, the LED light 16 turns on at the same time, which enables the visual detection of the effective activation of the corresponding microswitch 14 or 15. In addition to the two microswitches 14 and 15, on the circuit board 12 there are two other microswitches 114 and 115, the function of which will be better specified later on in the description.

To amplify the light emitted by the LED 16, a diffuser element 17 is provided which collects and amplifies the light emitted by the LED 16 to channel it toward an opening 18 made in the second half-shell 6.

The diffuser element 17 is advantageously made up of a transparent plastic body, preferably made of ABS.

As can be seen in Figures 4 and 5, the diffuser element 17 has a substantially prismatic shape and is housed in a seat 78 with matching shape obtained inside the second half-shell 6. The diffuser element 17 has a protruding portion in the shape of a tooth, best seen in the cross-section detail of Figure 7, consisting of an inclined surface 19a and a flat surface 19b. The inclined surface 19a favours the introduction and installation of the diffuser element 17 in the seat 78 through insertion and pressure, while the flat surface 19b provides a stop surface against a counteracting surface 78a of the seat 78 which prevents said diffuser element 17 from coming out.

On the electronic circuit board 12, as shown in Figure 5, there is also a housing 20 for a battery, the latter not shown in the figure, which feeds the electronic part 13 of the control 1.

The second half-shell 6 has four circular through openings 21, 22, 23 and 24 made at the level of the four microswitches 14, 15, 114 and 115.

On the surface 6a toward the outside of the second half-shell 6 at the level of said circular openings 21, 22, 23 and 24 there are respective housings 25, 26, 27 and 28 for the activation buttons 2, 3, in the present case said buttons being only two. The housings 25, 26, 27, 28 are formed by a lowered area with respect to the outer surface 6a and have holes 29 suited to receive corresponding pins 30 protruding from the buttons 2, 3. When the buttons 2, 3 are positioned in the respective housing 25, 26 in the second half-shell 6, the insertion of the pins 30 through the holes 29 enables the correct positioning and alignment of the buttons 2, 3 in the housing.

Each button 2, 3 has a portion facing the outside 2a, 3a with a substantially circular shape upon which the user pushes with his/her fingers, and a portion facing the inside 2b, 3b, visible in Figure 5 and suited to be placed in contact with the area where the microswitches 14 and 15 operate. Said portions 2a, 3a, 2b, 3b are substantially rigid and are supported by an elastic base portion 31 which joins the two buttons 2, 3. The elastic portions 31 enables the movement of each button 2, 3 when it is activated and favours its return to the rest position when it is released. The elastic return function is also favoured by the contact with the micros witches 14, 15 which themselves tend to return elastically to the rest position after their activation.

A cover element 32 is externally connected to the casing 4, and in particular to the second half-shell 6, at the level of the buttons 2, 3.

In particular, the cover element 32 has two circular through openings 33, 34 designed to house the respective push portions 2a, 3a, of the buttons 2 and 3. Peripherally the cover element 32 has elastic fins 32a, three in number, equipped with teeth that are suited to snap into their respective housings 6b provided in the second half-shell 6.

A protruding element 35 of the cover element 32 fits into a corresponding hole 6c of the second half-shell 6 in order to achieve the correct positioning of the cover element 32 on the second half-shell 6.

The cover element 32 can therefore be easily connected to the second half-shell 6, as well as easily disconnected from it, and is housed in the second half-shell 6 in a recessed area with matching shape such that when the cover element 32 is connected with the half-shell 6, as is best shown for example in Figure 1, externally it is substantially at the same level.

Finally, on the casing 4 there is a through-hole 37, made up by the respective portions of through hole 37a and 37b made in the two half-shells 5 and 6 for the insertion of a possible control-carrying element.

The design of the cover element 32 that is removably connected to the half-shell 6 so as to house the two buttons 2, 3 enables the maintenance operations of the control 1 to be made easier.

In fact, with reference to Figure 7, when the user wishes to open the control 1 to perform maintenance, which could consist, for example, in the replacement of the battery or the replacement or repair of the electronic circuit board 12, the fixing screw 7 is loosened and the first half-shell 5 is separated from the second half-shell 6. In carrying out this operation, no element of the control 1 comes off, in particular the buttons 2 and 3 are permanently confined between the cover element 32 and the second half-shell 6. Upon completion of the maintenance operations, it will be sufficient to simply reconnect the first half-shell 5 to the second half-shell 6 by means of the fixing screw 7, without any concern for the buttons, as occurs in the case of controls belonging to the known art.

Conversely, if maintenance is required on the buttons 2, 3, for example to replace or clean them, it will be sufficient to simply disconnect the cover element 32 from the second half-shell 6 with no need to open the control 1 completely, that is, with no need to detach the first half-shell 5 from the second half-shell 6. Therefore, in this case, maintenance operations are easier compared to those required by the controls of the prior art.

Further, this embodiment enables interventions on the control 1 in order to adapt it to individual aesthetic needs, given that the cover element with a specific aesthetic characteristic can be replaced with another with a different aesthetic appearance, for example, a different colour.

The two half-shells 5 and 6 are preferably made of a plastic material and obtained by moulding.

Thus the embodiment described herein, with the particular configuration of the various components starting with the electronic circuit board 12, the use of the diffuser element 17 which is applied by means of a snap-lock to the second half- shell 6, the buttons 2, 3 connected with the housings 25, 26, to the cover element 32 connected by means of a snap-lock to the second half-shell 6, determines for the two half-shells 5 and 6 a geometric shape that is advantageously devoid of undercuts, which simplifies the moulding operations thanks to simplified movements of the moulds. This leads to contained mould production costs and shorter production times for the half-shells 5, 6.

As described above, the control 1 includes the use of two buttons 2 and 3 which, in this particular case, cause, respectively, the opening and the closing of a gate activated by the respective microswitch 14 and 15. In this embodiment, therefore, the two microswitches 114 and 115 described are not used and indeed there is no button to activate them.

Nonetheless, the presence of the four microswitches 14, 15, 114, 115 enable the control 1 to be made modular, as it is possible to easily increase its functions through some simple operations which will be explained below in the description of the variant embodiment of the invention shown in Figures 8 to 12. This embodiment differs, in fact, from the first embodiment described with reference to Figures 1 to 7, as it includes two additional buttons 52, 53 with substantially the same shape, namely mirror-like, as the first two buttons 2, 3, and as the cover element 72 is provided with four circular through openings 33, 34, 63, 64, instead of two, suited to house the push portions 2a, 3a, 52a, 53a of the four buttons 2, 3, 52, 53.

The addition of the two buttons 52, 53 in a control device of the type described here, that is, for a gate remote control, can, for example, enable the use of the same control 1 to open two different gates, or a fence gate and a garage door, or in any case two separate remote-controlled systems or apparatuses.

Alternatively, the addition of the two buttons 52, 53 enables further functions to be added for controlling the same gate, in addition to the opening and closing functions, for example a STOP opening/closing command and a RESTART opening/closing command.

Therefore, the two buttons 52, 53, and the corresponding microswitches 114, 115 may activate the same opening and closing functions as the first two buttons 2 and 3 and their respective switches 14, 15, or even perform different functions. It is clear from the above that to switch from a 2-function 2-button control of the type described with reference to the first embodiment in Figures 1 to 7 to a 4- function 4-button control of the type described with reference to the second embodiment in Figures 8 to 12 it is sufficient to simply add the pair of buttons 52, 53 and replace the cover element 32 having only two openings 33, 34, with a cover element 72 with four openings 34, 34, 63, 64.

With regard to the management of the signals emitted after the activation of the additional buttons 52, 53, according to the invention the electronic components 13 can be already designed so as to detect the possible use of one of the four microswitches 14, 15, 114, 115 with no need to reprogram the electronic component 13 itself.

While the embodiments described above are provided with four switches, it is clear that other variant embodiments may include a different number of microswitches suitably placed on the circuit board 12. The desired final configuration for the control 1 according to the desired arrangement is then implemented with simple operations to add/remove buttons and replace the cover element with one equipped with an adequate number of openings corresponding to the number of buttons to be used. For example, a control can be provided which is suited to house one or more pairs of on-off buttons to control corresponding household apparatuses, such as lights, electric shutters, split air conditioning systems, or a pair of on-off buttons for alarms, which can be particularly useful in an automated home.

Figures 13 and 14 show a variant embodiment of the control device 1 described with reference to Figures 7 to 12, differing from the latter owing to the fact that the cover element 82 does not have through openings at the level of the four buttons 2, 3, 52 and 53, but rather it has four areas 83, 84, 85, 86 equipped with an elastically yielding membrane suited in any case to allow the buttons 2, 3, 52, 53 below to be pushed.

Said membrane can be a separate element applied to the second half-case, or be built in during the production phase of the cover element 82, for example during the moulding process using different co-moulded materials.

Said elastic membrane provides greater air-tightness compared to the embodiments described above.

In the previously described embodiments of the present invention, the buttons are all connected to the second half-case and are therefore placed on the same side of the casing. However, in other variant embodiments, the microswitches can be placed on opposite sides of the circuit board, so that the respective buttons and cover elements are positioned on both sides of the casing.

Moreover, additional or replacement elastic thrust elements may be included, such as helical springs that act on the buttons to keep them in the rest position and make them return to said position once they have been pushed.

Therefore, it has been demonstrated that the present invention achieves the set objects. In particular, it makes it possible to provide a control device where maintenance operations are simplified compared to the control devices of known type.

While the present invention has been described with reference to the particular embodiments represented in the figures, it should be noted that the present invention is not limited to the particular embodiments shown and described herein; on the contrary, further variant embodiments are within the scope of the present invention defined in the claims.
