PUSH BUTTON PANEL FOR NAUTICAL ELECTRO-MECHANISM

DESCRIPTION

Technical field of the invention

The present invention generally relates to the technical field of nautical equipment. Pi? in particular, the invention relates to a push-button panel with double control switch for a nautical electro-mechanism.

State of the art prior to the invention

Various electromechanisms are installed on board pleasure boats, yachts, ships and the like, which are used to effortlessly perform tensioning maneuvers of ropes or ropes.

For example, motorized electro-mechanisms are available, which require, for their operation, an electric power supply and an actuation button that can be controlled by the crew. This category includes motorized winches, motorized capstans, motorized windlasses and motorized cleats, i.e. devices that are operated by a motor, typically positioned below deck, to wind the rope or rope so as to stretch it to the desired tension.

The activation button of the motorized electro-mechanisms listed above ? typically pedal, ie the type suitable to be operated with the foot, and typically provides a fixed structure in which? the circuitry is housed, permanently linked to the boat or to the relative electro-mechanism to be controlled, and a corresponding mobile structure, which can be moved or deformed by the user, comprising the electric switch which closes/opens the electric circuit. The foot switch? it is also sealed to prevent infiltration of water or humidity? which would oxidize the circuitry.

However, the pedal switches traditionally used in the nautical sector have the following drawbacks.

The circuitry traditionally installed on a known pedal pushbutton provides that the pushbutton manages only one direction of rotation. It is in fact a device of the on/off type, in the sense that, when the button is pressed with the foot, the motor of the motorized electro-mechanism rotates so as to stretch the rope or rope, and, once the tension has been reached desired, the rotation of the motor is stopped by lifting the foot from the pedal.

It follows that, with pedal push buttons of the known type, it is not It is possible to control the two directions of rotation of the drive motor of a nautical electro-mechanism, for example a motorized winch. Therefore, if you want to rotate the motorized winch in the opposite direction to that of tensioning the rope or rope, i.e. to loosen or release the rope or rope, ? it is necessary to provide a second pedal button, typically provided in the immediate vicinity of the tensioning button.

There? ? naturally disadvantageous, as it lengthens and complicates the installation times of the motorized electro-mechanisms on the boat.

Summary of the invention

The main purpose of the present invention ? therefore that of making available a push-button panel for applications in the nautical sector, ie a control push-button panel for motorized or in any case electrically powered nautical electro-mechanisms, which solves the drawback of traditional push-buttons in a simple and effective way.

Pi? in particular, main purpose of the present invention ? that of making available a push-button control for a nautical electro-mechanism configured to allow the user to rotate the electro-mechanism in both directions of rotation according to need.

Yet another object of the present invention? that of making available a control push-button panel for nautical electro-mechanisms configured in such a way as to receive the lowest possible input voltage, regardless of the supply voltage.

Yet another object of the present invention? that of making available a control push-button panel for a nautical electro-mechanism configured in such a way as to prevent a possible short circuit in the event of a fault, incorrect use of the push-button panel and/or infiltration of water into the drive motor of the nautical electro-mechanism to be controlled .

Not the last purpose of the present invention ? that of making available a control push-button panel for a nautical electro-mechanism, which can be produced in times and at lower costs than those for the production of wall frames in traditional plastic material. These and other objects, which will appear better in the following of the present description, are achieved by a control push-button for a nautical electro-mechanism according to the independent claim 1. Preferred characteristics of the control push-button for a nautical electro-mechanism are set forth in the dependent claims from 2 at 10.

The invention therefore relates to a push button control panel for a nautical electro-mechanism comprising a housing, a unit? of electronic control, of electrical connection of the button panel to the nautical electro-mechanism to be commanded, and actuation means of the nautical electro-mechanism positioned inside the housing and in electrical connection with the unit? of electronic control.

The button panel? characterized in that the actuation means comprise a first and a second push-button switch, each configured to actuate the nautical electro-mechanism according to a respective direction of rotation, and in that in the housing ? obtained a dividing septum between the first and the second button switch.

Thanks to this combination of characteristics, and in particular thanks to the fact of providing two push-button switches suitably separated from each other, ? Is it possible to obtain a push-button panel with integrated dual commands, i.e. able to allow the user to rotate, reliably and without the possibility? of error, the electro-mechanism rotates in both directions according to need. In particular, the presence of a partition between the first and second push-button switch advantageously facilitates the user in activating the desired push-button switch.

Detailed description of preferred embodiments of the invention

With reference to Figures 1 to 4, a control push-button panel for a nautical electro-mechanism according to a preferred embodiment of the present invention is illustrated.

The push-button panel, indicated in general with the reference number 100, comprises a housing 20 and means 30 for the electric actuation of a nautical electro-mechanism which the push-button panel 100 is? intended to command, positioned inside the housing 20.

The housing 20 comprises a base 21, which can be connected, permanently or removable, to an external structure, typically the deck of a boat, and a cover 22 coupled above the base 21 and movable, with respect to the base 21, between a condition closure of the housing 20 (cf. Figure 1), in which ? access to the electric actuation means 30 is prevented, and a condition of opening of the housing 20 (see Figure 2), in which a user has access to the electric actuation means 30 positioned inside the housing 20. In the form of the embodiment illustrated in Figures 1 to 4, the lid 22 is pivoted to the base 21 by means of a hinge 23. Of course ? It is possible to provide alternative coupling means between the base 21 and the lid 22, such as interlocking coupling means, for example by providing the lid 22 with elastic tabs which engage in corresponding seats formed in the base 21.

The lid 22 preferably has a tab 24, protruding frontally from the lid 22, and which, when gripped by the user, facilitates the opening and closing of the housing 20. The base 21 and the lid 22 of the housing 20 are preferably made in stainless steel.

The electric actuation means 30 comprise a first push-button switch 31 and a second push-button switch 32, preferably of the pedal type.

Each pushbutton switch 31 and 32 ? configured to operate the nautical electro-mechanism according to a respective direction of rotation. By way of example, and assuming that the nautical electromechanism is a motorized winch, the first push-button switch 31 of the push-button panel 100 is? configured to rotate the motorized winch according to a first direction of rotation, cos? to obtain the tension of a rope or rope, while the second button switch 32 ? configured to rotate the motorized winch according to a second direction of rotation, opposite to the first, thus obtaining the slack of the rope or rope. Of course, and in a completely equivalent way, the first pushbutton switch can? be operated to slacken the rope or rope and the second push button switch can? be operated to tension the rope or rope.

As shown in greater detail in Figure 4, each push-button switch 31 and 32 comprises a respective pair of electrical contacts 33 and 34, each pair being fixed on a flat element 25 so as to project above it. The electric contacts 33 and 34 are preferably made of copper and the base element, preferably of plastic material, is coupled to the base 21 of the housing 20.

In the base 21, preferably in correspondence with each pair of electric contacts 33 and 34, holes 26 are also made for the passage of a respective conduit 27 for housing electric wires (not shown) connecting each pair of electric contacts 33 and 34 to a?unit? electronic control unit 50 (see Figure 7), preferably positioned below deck, for electrical connection of the push-button panel 100 to a motor M (see Figure 7) for operating the nautical electro-mechanism to be controlled with the push-button panel 100. The unit? electronic control 50 will come? described in greater detail below with reference to Figure 7. The conduits 27 for the passage below the deck of the electric wires of the push-button switches 31 and 32 extend from the flat element 25, on the opposite side to that of the fixing of the pairs of electric contacts 33 and 34.

Each button switch 31 and 32 also comprises a respective cap 35 and 36, made of water-resistant plastic material, for example rubber or silicone, arranged over the respective pair of electric contacts 33 and 34. The caps 35 and 36 represent the collapsible portion of each push button switch 31 and 32.

Inside each shell 35 and 36 ? a respective element for closing/opening the electric contacts 33 and 34 is provided. In the embodiment illustrated in Figures 1 to 4, the elements for closing/opening the electric contacts consist of metal washers 37 and 38, each fixed, for example fitted, at an internal upper surface of the respective cap 35 and 36. Each washer 37 and 38 therefore has a free or uncovered surface 37a and 38a facing the respective electric contacts 33 and 34 and suitably distanced from them from the domed shape of the respective cap 35 and 36. The distance between the free or uncovered surface 37a and 38a of the washer 37 and 38 and the respective electric contacts 33 and 34 ? further guaranteed by a return spring 39 and 40, placed between the electric contacts 33 and 34 and the respective washer 37 and 38. In particular, each return spring 37 and 38 contributes to guaranteeing that, in rest or idle condition of the pushbutton switches 31 and 32, the uncovered surface 37a and 38a of the washers is suitably spaced from the respective electrical contacts 33 and 34, so as to avoid unwanted activation of the respective pushbutton switch 31 and 32. Inside the base 21 of the ?bay 20 ? furthermore provided is a dividing partition 28 of the push-button switches 31 and 32, which arises, between the two push-button switches, from a flat support 29. The flat support 29 is preferably arranged in the base 21, below the flat element 25 supporting the electric contacts 33 and 34, and extends between the two conduits 27 for housing electric wires outgoing from the electric contacts 33 and 34. The partition 28 between the two push-button switches 31 and 32, advantageously assists the user in activating the desired push-button switch. Preferably, the dividing septum 28 ? coated with a layer 41 of water-resistant plastic material, the same as that in which the caps 35 and 36 are made, the layer 41 being connected to the caps in correspondence with the flat element 25 supporting the electric contacts 33 and 34 of the switches push button 31 and 32.

Preferably, the caps 35 and 36 and the coating layer 41 of the partition 28 of the push-button switches 31 and 32 are made in one piece, thus acting as a water and moisture-tight sealing element. for the respective electric contacts 33 and 34. Above the dividing septum 28, in particular in correspondence with the covering layer 41, if it were provided, ? a seat 42 is obtained for the interlocking reception of a tooth 22a protruding from an upper inner surface of the cover 22 of the housing 20. The interlocking coupling between the tooth 22a and the respective reception seat 42 allows, advantageously, to keep the lid 22 coupled to the base 21, in the closed condition of the housing 20.

With reference to Figures 5 and 6, a push-button control panel for a nautical electromechanism according to an alternative embodiment of the present invention is illustrated. The push-button panel, indicated in general with the reference number 1100, differs from the push-button panel 100, described above and illustrated in Figures 1 to 4, due to the different configuration of the push-button switches, more in particular due to the different positioning of the electrical contacts and of the respective activation or closure washer of the button switch.

The push-button panel 1100 therefore comprises a housing 120 and means 130 for electric actuation of a nautical electro-mechanism, positioned inside the housing 120. The housing 120 comprises a base 121 and a cover 122 coupled above the base 121, preferably pivoted to the base by means of a hinge 123, and movable, with respect to the base 121, between a closed position of the housing 120 and an open position of the housing 120.

The lid 122 preferably has a tab 124, protruding frontally from the lid 122, and which, when gripped by the user, facilitates the opening and closing of the housing 120.

Preferably the base 121 and the lid 122 of the housing 120 are made of stainless steel.

The electric actuation means 130 comprises a first pushbutton switch 131 and a second pushbutton switch 132, each configured to operate the nautical electro-mechanism according to a respective direction of rotation.

Each push-button switch 131 and 132 comprises a respective magnetic attraction electric contact 133 and 134, which, instead of project above from a flat element coupled to the base of the housing, as in the case of the push-button panel 100, ? incorporated in the flat element 125. In particular, each electric contact with magnetic attraction 133 and 134 is made up of a pair of plates in magnetic material.

From the base 121, preferably in correspondence with each electric contact with magnetic attraction 133 and 134, respective ducts 127 extend, which project downwards from the flat element 125 and have the same function as the ducts 27 previously described with reference to the push-button panel 100.

Each push-button switch 131 and 132 also comprises a respective cap 135 and 136, made of water-resistant plastic material, for example rubber or silicone, arranged above the respective pair of magnetic attraction electric contacts 133 and 134.

Inside the base 121 of the housing 120 ? furthermore, a dividing partition of the push-button switches 131 and 132 is provided, which is entirely similar to that described with reference to the button panel 100 described above with reference to Figures 1 to 4 and which therefore will not be? further described here.

Superior to the dividing septum ? an interlocking reception seat of a tooth 122a protruding from an upper inner surface of the cover 122 of the housing 120 is obtained. The interlocking coupling between the tooth 122a and the respective reception seat advantageously allows the cover 122 to be kept coupled to the base 121, in the closed condition of the housing 120.

Inside each shell 135 and 136? a respective closing/opening element of the magnetic attraction electric contact 133 and 134 is provided. In the embodiment illustrated in Figures 5 and 6, the closing/opening elements of the magnetic attraction electric contacts 133 and 134 consist of magnetic washers 137 and 138, in the form of permanent magnets. Each magnetic washer 137 and 138, instead? have a free or uncovered surface facing the respective electric contacts, as in the case of the washers 37 and 38 of the button panel 100, ? incorporated in the respective cap 135 and 136.

Also in this embodiment, the distance between each magnetic washer 137 and 138, incorporated in the respective cap 135 and 136, and the respective magnetic attraction electric contacts 133 and 134, incorporated in the flat element 125, is? determined, in addition to the dome shape of the cap, by a respective return spring 139 and 140, interposed between the respective electric contact with magnetic attraction 133 and 134 and the respective magnetic washer 137 and 138.

In particular, and how will it come? described in detail below, upon pressing the pushbutton switch 131 and 132, each magnetic washer 137 and 138 moves into proximity of the respective electric contact with magnetic attraction 133 and 134, which is subjected to a magnetic field. Due to the effect of the magnetic field, polarities are generated in the blades of the contacts 133 and 134 opposing sides, causing an attractive force which causes the plates to flex against each other, thus making an electrical contact. When the influence of the external magnetic field ceases, i.e. when the magnetic washers 135 and 136 move away from the respective contact due to the effect of the return spring 139 and 140, the plates separate with consequent opening of the contact and restoration of the initial situation (at rest ). Since the electrical contacts and the washers do not have uncovered faces, but are incorporated, respectively, in the caps and in the flat element, they are advantageously further protected from corrosion or oxidation which may occur, particularly in a marine environment, and which could compromise durability and functionality? of push button switches.

With reference to Figure 7, it shows in detail the wiring diagram of the unit? of electronic control 50 of the button panel 100, 1100 according to the invention.

The unit of electronic control 50 comprises a DC-DC converter 54, connected between an electric power source 55 and the input of the first 31, 131 and of the second push-button switch 32, 132. The DC-DC converter 51 allows to supply input to the push-button panel 100, 1100 the lowest possible voltage, preferably 12V in direct current, regardless of the supply voltage, which can? vary between 10V to 48V DC. There? advantageously avoids the presence of high currents in the electric wires, thus reducing the risk of fire in the event of a short circuit and at the same time allowing the use of small section electric wires, with obvious savings both in terms of space and economic terms.

The output of the first pushbutton switch 31, 131 ? connected to the input of a first relay? and the output of the second button switch 32, 132 ? connected to the input of a second relay? 52. Each relay? 51 and 52 ? connected to the power source 54 and to the actuation motor M of the nautical electro-mechanism to be controlled with the push-button panel 100, 1100. More? in particular, the first and second rel? 51 and 52 comprise a respective electromagnet 56 and 57, consisting of a coil of electrical conductor wire, generally of copper, wound around a core of ferromagnetic material, and a moving contact 58 and 59 actuated by the electromagnet 56 and 57.

The first and second relays, 51 and 52, are connected electrically to each other in such a way that, in the event that the user presses both the push button switches 31, 131 and 32, 132, inadvertently or due to a failure in the push-button panel, a short circuit is not generated. The relays? 51 and 52 are also electrically connected to each other and in such a way that, in rest conditions, the electromagnets 56 and 57 and the motor M are at the lowest electric potential. low. There? in order to reduce the pi? possible effects of corrosion due to any galvanic currents that can be generated in a humid or saline environment as pu? be the marine environment. Furthermore, being the motor M at the electric potential pi? low, in the event of a prolonged stop of the nautical electromechanism, a possible infiltration of water into the motor M would not cause any short circuit.

Will I come the operation of the push-button panel according to the present invention has now been described.

Assume, by way of example, that a user wishes to use the above-described push-button panel 100, 1100 to control a motorized winch installed on a boat in order to stretch a rope or rope.

First, the user lifts the closing lid 22, 122 so as to have access to the pushbutton switches 31, 131 and 32, 132 and presses the first pushbutton switch 31, 131 with his foot, thus to rotate the motorized winch at a first speed? of rotation. Following the pressure exerted, and with particular reference to the pushbutton panel 100, the silicone cap 35 of the first pushbutton switch 31 collapses and the return spring 39 compresses until the uncovered surface 37a of the metal washer 37 fixed in the cap abuts against the electric contacts 33 protruding from the flat element 25, closing the switch. Instead, in the case of the push-button panel 1100, following the pressure exerted, the silicone cap 135 of the first push-button switch 131 collapses and the return spring 139 compresses until the magnetic washer 137 incorporated in the cap moves close to the of the magnetic attraction electric contact 133 incorporated in the flat element 125, causing the attraction of the blades and the consequent closure of the switch.

In particular, when each magnetic washer 137 and 138 is in the vicinity? of the respective magnetic attraction electric contact 133 and 134, the latter is subjected to a magnetic field. Due to the effect of the magnetic field, polarities are generated in the blades of the contacts 133 and 134 opposing sides, causing an attractive force which causes the plates to flex against each other, thus making electrical contact. When the influence of the external magnetic field ceases, i.e. when the magnetic washers 135 and 136 move away from the respective contact due to the effect of the return spring 139 and 140, the plates separate with consequent opening of the contact and restoration of the initial situation (at rest ).

The closure of the first button switch 31, 131 causes the passage of electric current inside the coil of the electromagnet 56 and the consequent closure of the mobile contact 58. The closure of the mobile contact 58 of the first relay? 51 causes, in turn, the feeding of the motor M, with consequent rotation of the winch in the first direction of rotation, tensioning of the rope or rope.

When the user lifts his foot from the first push-button switch 31, 131, due to the return action of the spring 39, the washer 37 separates from the electric contacts 33, and the magnetic washer 137 moves away from the magnetic contact 133, with consequent cessation of the magnetic field and separation of the plates. The switch opens, thus interrupting the rotation of the motorized winch in the first direction of rotation.

Assume now that the user wishes, still using the push-button panel 100, 1100, to operate the motorized winch in order to slacken the rope or rope.

Again, the user lifts the closing lid 22, 122 so as to have access to the pushbutton switches 31, 131 and 32, 132 and presses the second pushbutton switch 32, 132 with his foot, thus to rotate the motorized winch in a second direction of rotation, opposite to the first.

Following the pressure exerted, and with particular reference to the push-button panel 100, the silicone cap 36 of the second push-button switch 32 collapses and the return spring 40 compresses until the uncovered surface 38a of the metal washer 38 fixed in the cap abuts against the electric contacts 34 protruding from the flat element 25, closing the switch.

Instead, in the case of the push-button panel 1100, following the pressure exerted, the silicone cap 136 of the second push-button switch 132 collapses and the return spring 140 compresses until the magnetic washer 138 incorporated in the cap moves close to the of the electric contact with magnetic attraction 134 incorporated in the flat element 125, causing the reciprocal attraction between the plates due to the effect of the magnetic field generated, thus closing the switch.

The closure of the second push-button switch 32, 132 causes the passage of electric current inside the coil of the electromagnet 56 and the consequent closure of the mobile contact 59. The closure of the mobile contact 59 of the second relay? 52 causes, in turn, the feeding of the motor M, with consequent rotation of the winch in the second direction of rotation and loosening of the rope or rope.

When the user lifts his foot from the second push-button switch 32, 132, due to the return action of the spring 40, the washer 38 separates from the electric contacts 34? in the case of the button panel 100 - and the magnetic washer 138 moves away from the magnetic attraction electric contact 134 ? in the case of the push-button panel 1100 - by opening the switch and thus interrupting the rotation of the motorized winch in the second direction of rotation.

If the user inadvertently presses both push-button switches 31, 131 and 32, 132 at the same time, the power supply to the relays is cut off. 51 and 52 preventing a short circuit. The button panel what? obtained ? therefore equipped with intrinsic self-protection. In particular, the simultaneous activation of both the push-button switches 31, 131 and 32, 132 causes an idle condition of the push-button panel 100, such that the simultaneous activation of both the push-button switches ? equivalent to the non-activation of the same.

From the description given, the characteristics of the push-button panel of the present invention are evident, so as the relative advantages are evident.

? Finally, it is clear that the push-button panel is cos? conceived ? susceptible to numerous modifications and variations; moreover, all the details can be replaced by technically equivalent elements.
