    [0002] Safety cap for fuel tank in vehicles.
    [0003]
    [0004] Object of the invention
    [0005]
    [0006] The invention is intended to prevent theft or unwanted extraction of fuel in a motor vehicle, such that when the safety cap of the invention is housed in the inlet of a fuel tank, this cap is fully secured without the possibility of Extraction, by means of a mechanism comprising articulated flat bars or profiles and an endless screw, which mechanically secure the assembly to the tank from its interior, in addition the cap of the invention has a lock and safety plates that prevent access to the cited mechanism, preventing possible theft of fuel.
    [0007]
    [0008] The safety cap for fuel tank in vehicles of the invention is comprised of a cover, a mechanism, a safety lock, safety plates, a bushing, a chain and mechanical actuation means, such that a safety key and a crank.
    [0009]
    [0010] The field of application of the invention is comprised within the mechanics sector, specifically in the internal combustion engine plugs in large tonnage motor vehicles.
    [0011]
    [0012] Background of the invention
    [0013]
    [0014] At present, fuel thefts have become an added cost for transport companies and freelancers, so it is necessary for vehicles to incorporate anti-theft systems in their tanks. Given this situation, all that is left is knowledge and prevention. Self-protection is the basic action that any professional driver must take along the route and even the entrepreneur himself, when the driver of his trucks is not fully trusted. For this, it is advisable to mount in the tanks devices that prevent or warn of the transfer of fuel, in addition to using the supervised rest areas during the regulatory stops.
    [0015]
    [0016] Therefore, there are many records related to different types of security plugs or anti-theft plugs, intended for the protection of fuel in tanks of large tonnage vehicles such as trucks, vans, buses or similar.
    [0017]
    [0018] Among the records found, we highlight the utility model ES0022845U entitled "Cap for the fuel tank of cars, which prevents the furtive extraction of the liquid" where a type of cap consisting primarily of an extension or tubular body is disclosed, with vertical slits on its lateral surfaces and that it is closed in its lower part, in such a way that the assembly allows the entrance of liquid into the tank, but that makes it impossible to introduce a tube or similar, by which the liquid can be extracted from the interior of the deposit.This record currently in the public domain has been the basis of different security plugs for deposits that are currently on the market, in which the configuration on the lateral surfaces of the tubular bodies has been modified, specifically in their slits or side walls through which fuel enters through sections d specially designed for the flow inlet, but that makes it impossible or difficult to exit through them.
    [0019]
    [0020] Unlike the safety cap object of the present invention, the safety plugs as described need a previous installation in the inlet port of the tank to be protected, However, with this safety cap, this installation is unnecessary because the cap as a whole can be easily inserted and removed every time a user needs to refuel, however once the cap is secured in the tank inlet , it becomes physically unfeasible to access inside the tank since the assembly is fully mechanically secured by gripping its mechanism below the internal cavity of the tank mouth. Thus, when the safety cap of the invention tries to be forced, it rotates on its own axis, but in no case allows its extraction from the mouth, which is nonexistent in the aforementioned registry. Therefore, we consider that with the safety cap object of the present invention provides improvements and structural and technical differences different from what is known in this sector.
    [0021]
    [0022] Another record to highlight is the utility model ES0237626U entitled "Cap for fuel tank of motor vehicles" in which a cap is disclosed that internally has an eccentric pivot that serves to mount a plate that rotates eccentrically around said pivot, which acts as a locking bolt for the cap and also has a cylindrical projection through which a diametral bar protrudes through two windows, which serves as a bar for fixing the cap to the mouth of the fuel tank. The difference between this register and the cap The object of the invention is fundamentally structural and functional, that is, structural because the safety cap of the present invention is constituted by a mechanism formed by metal profiles or bars articulated with each other that are actuated by the mechanical actuation on a screw without purpose, which is totally different from the one presented in the aforementioned record; and functional because the resistance to the extraction or violation offered by the safety cap of the invention, substantially improves to that presented by the indicated rectangular registration plate, since the aforementioned registration plate only offers resistance at a point on the edge of the mouth of the container, while in the lid of the invention this resistance is present in each and every one of the points of the cap of the cap against the inlet mouth of the tank. The cap of the invention also has a bushing located around the neck of the tank that prevents breakage of the mouth of said tank in case of theft, thus protecting the internal mechanism of the cap; and it also has a safety plate, located on a lock, which by means of a seal prevents access to the mechanism preventing the removal of the safety plug, even to the drivers themselves, all in a totally different way and improved to what is known so far In this sector. In addition, it is convenient to note that the cap of the invention grips the mouth of the tank both externally and internally, while in the case of the register indicated above ES0237626U, this grip or attachment is only possible from the inside.
    [0023]
    [0024] Therefore, the safety cap of the present invention provides differential improvements, compared to conventional fuel tank caps in motor vehicles, by means of a different and improved structural configuration than that presented in the caps known to date. These differences make the cap of the invention more resistant and safe against possible theft or unwanted manipulation; In addition, another consequence of the structural difference of its mechanism is that the cap of the invention can be adapted to any height of the neck of the mouth of a tank, in a totally different way than the safety caps currently known, which have a fixed grip height. Thus, and according to the above, with the safety cap object of the invention goes a step further in the sector of the plugs for internal combustion engines, since, through a certain configuration, a type of plug is obtained of different security, improving what is known so far in this sector.
    [0025]
    [0026] Next, a detailed description of the invention is completed that completes these general ideas introduced at this point.
    [0027] Description of the invention
    [0028]
    [0029] The safety cap for fuel tank in vehicles of the invention is comprised of a cover, a mechanism, a safety lock, safety plates, a bushing, a chain and mechanical actuation means, such as a safety key and a crank; in such a way that the mechanism is internally attached to the lid, the security lock is housed inside the lid body, the safety plates are located on the lid protecting the lock, the bushing is located around the neck of the mouth of the tank and the chain is fixed at one end of the mechanism.
    [0030] The safety cap of the invention is constituted by rigid elements, preferably metallic and structurally configured so that all the parts that compose it, except the upper face of the lid, are introduced into the cavity of the inlet mouth of any fuel tank of a motor vehicle. So, when the cap of the invention is located inside the mouth of a tank, the mechanism that composes it is activated by means of a crank that rotates an endless screw that jointly moves flat profiles or bars, that mechanically strengthens the mechanism of the cap inside the tank, without the possibility of extraction.
    [0031]
    [0032] The lid is the upper part of the safety cap, and is formed by a body that has a flat circular surface, whose perimeter has a diameter greater than the mouth of the tank; while inferiorly it has a cylindrical surface, whose perimeter is of a smaller diameter than the mouth of the tank. It is emphasized that, in the aforementioned flat circular surface, specifically in its lower contour, there is a perimeter cavity that is in direct contact with the surface of the tank mouth, which is the surface where the grip between the cap and the mouth occurs of the deposit. In the central part of the lid there is also a recess where a security lock is housed. Another detail of the invention is that, on both sides of said cover, it has fixed plates where a mechanism is attached.
    [0033]
    [0034] This mechanism is made up of rigid flat profiles or bars articulated with each other, so that an endless screw, which is housed in a through hole that has the central hole of the lid, acts as a driving element. The bars are positioned symmetrically to the central axis of the lid and two of them are symmetrically attached to the lid by each of the plates, previously cited. The worm that coincides with the central axis of the cover is conveniently secured to it by a stop nut or the like. This worm is the means by which the mechanism is activated, that is, the bars articulate jointly to the rotation of the worm by means of a feed nut or mobile nut with fins. In this way the worm, which is accessible with a crank through the cavity of the lid, rotates on its axis and transmits the vertical movement to the mobile nut, which in turn transmits its movement to the articulated bars in their fins. It is noted that the worm is accessible by means of the crank cited when a safety lock, described below, has not been introduced on the cover.
    [0035]
    [0036] Therefore, when the movement of the said mobile nut is down, the bars that make up the mechanism open under the inner walls of the tank mouth, so that the ends of at least two flat bars protrude through the mouth inside the tank, the assembly being secured or held internally to the mouth. In this way, the assembly is axially secured without the possibility of extraction, but at the same time it allows the assembly to rotate on its own axis. Similarly, when a twist is made on the worm in the opposite direction to that described, the movable nut rises in such a way that the bars that move in solidarity with the vertical movement of the nut fold over themselves, no longer protruding below from the inner mouth of the tank and the safety cap assembly of the invention can be removed from the mouth.
    [0037] It is noted that, in order to externally reinforce the neck of the tank mouth, additionally the cap of the invention incorporates a bushing that is located externally to the neck of the tank. This bushing protects the entire outer perimeter of the neck of the mouth, preventing the neck of the tank from being forced or bent with some type of tool. Between the bushing and the neck of the tank there is a clearance that allows the free rotation of this protection. The inclusion of this bushing means that the set has an additional security element not present in the existing caps in the market.
    [0038]
    [0039] Another detail of the invention is that at the end preferably of one of these bars, a metal chain is fixed that prevents the assembly of the safety cap of the invention from being lost or lost when it is removed from the tank, for example, in refueling. or similar.
    [0040]
    [0041] Once the mechanism is conveniently adjusted both internally and externally in the mouth of the tank, in the central recess of the previously mentioned lid, a safety lock is housed. This security lock is cylindrical and its dimensions are such that once it is housed inside the aforementioned recess, the clearances between them are non-existent. It should be noted that a tab protrudes at a midpoint of this lock, which is housed in an internal hollow of the hole itself. This tab is operated by means of a security key.
    [0042]
    [0043] This lock is protected superiorly by plates that allow the introduction of a seal through them, thus preventing unwanted removal of the plug. Both plates are located on the upper body of the lid, such that one of them rotates eccentrically on the face seen of the lock through a rivet-type hole; while the other sheet is fixed on the surface of the cover by welding or the like. The two plates have a through hole in their vertical bodies, so that when both are facing each other, these holes coincide at the same point by which a strap or seal can be introduced that prevents the opening of the lock and therefore the extraction of the tank cap. The inclusion of these elements has the technical advantage of having a second security element against theft or unwanted openings.
    [0044]
    [0045] Therefore, when the safety cap as a whole is housed in the inlet mouth of a fuel tank, this cap is fully attached to the mouth of the tank both externally and internally, without the possibility of extraction. Therefore, the cap of the invention is mechanically secured in the mouth of the tank without the possibility of extraction, the rotation of the assembly being possible on its own axis, whereby the tank is completely closed while avoiding unwanted opening manipulations.
    [0046]
    [0047] In order to complete the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part thereof, where the following has been represented as an illustrative and non-limiting nature:

    [0063]
    [0064] Description of the drawings
    [0065]
    [0066] As shown in Figure 1 and Figure 2, the safety cap (1) of the invention is housed inside the mouth (21) of a fuel tank (2), such that all parts of the safety plug (1) except its upper face, corresponding to the upper face of a lid (12), are embedded inside the tank (2).
    [0067]
    [0068] Therefore, when the safety plug (1) as a whole is housed in the inlet mouth (21) of a fuel tank (2), this plug (1) is fully seized to the mouth (21) of the tank (2) both internally and externally, with no possibility of extraction. Thus, as shown in Figures 1 and 2, the safety plug (1) is mechanically secured in the mouth (21) of the tank (2) from its inside, by means of a mechanism (13) formed by bars (131) flat; and from the outside, by means of a cover (12) that superiorly fastens the assembly to the mouth (21) of the tank (2), in addition to a bushing (15) located perimeter between the cover (12) and the tank ( two). So the cap (1) is completely immobilized on the surface of the mouth (21) of the aforementioned tank (2), which is completely closed.
    [0069]
    [0070] On the other hand, Figure 3 and Figure 4 show the different parts that make up the safety plug (1) of the invention, which comprises a cover (12), a mechanism (13) attached inferiorly to the cover (12), a security lock (14) housed inside the body of the cover (12), safety plates (16) located on the cover (12) protecting the lock (14), a bushing (15) located around the neck of the mouth (21) of the tank (2), a chain (17), and mechanical actuation means, such that, a safety key and a crank (not shown) acting respectively on the lock (14) of Safety and mechanism (13).
    [0071]
    [0072] The safety cap (1) of the invention is rigid, preferably metallic and is housed inside the mouth (21) of a fuel tank (2), such that all parts of the safety cap (1), except for its upper face corresponding to the lid (12), they are inserted into the tank (2).
    [0073]
    [0074] As detailed in Figure 5, Figure 6 and Figure 7, the cover (12) is the upper part of the safety plug (1), and is formed by a body that has a flat circular surface superiorly whose perimeter has a diameter upper than the mouth (21) of the tank (2); while inferiorly it has a cylindrical surface, whose perimeter is of a smaller diameter than the mouth of the tank (2). Stressing that, in the aforementioned flat circular surface, specifically in its lower contour, there is a perimeter cavity (121) that is in direct contact with the surface of the mouth (21) of the reservoir (2), which is the surface where it is produced the grip between the cap (1) and the mouth (21) of the tank (2). In the central part of the lid (12) there is also a recess (122) where a security lock (14) is housed. Another detail of the invention is that on both sides of said cover (12), it has fixed on both sides plates (123) where a mechanism (13) is attached.
    [0075]
    [0076] In figure 3 and in figure 4 it is shown how this mechanism (13) is formed by rigid flat profiles or bars (131) articulated with each other, such that an endless screw (132), which is housed in a through hole that has the central hole (122) of the cover (1), it acts as a driving element. The bars (131) are positioned symmetrically to the central axis of the cover (12) and two of them are symmetrically connected to the cover (12) by each of the plates (123), previously cited. The worm screw (132) that coincides in position with the central axis of the cover (12) and is also secured to it by means of a stop nut or the like. This worm (132) is the means by which the mechanism (13) is activated, that is, the bars (131) jointly and severally articulate the rotation of the worm (132) by means of a mobile nut (133) with fins In such a way that the worm screw (132), which is superiorly accessible by mechanical means with a crank through the recess (122) of the cover (12), rotates on its axis and transmits the vertical movement to the nut mobile (133), which in turn transmits its movement to the bars (131) articulated in its fins.
    [0077]
    [0078] Therefore, as shown in the position shown in Figure 3, when the movement of the said mobile nut (133) is down, the bars (131) that make up the mechanism are deployed or open under the internal walls of the mouth (21) of the tank (2), in such a way that the ends of two flat bars (131) protrude through the internal mouth (21) of the tank (2), the assembly being secured or held internally to the mouth (21) . In this way, the assembly is axially secured without the possibility of extraction, while allowing the assembly to rotate on its own axis.
    [0079]
    [0080] Similarly, Figure 4 represents the folding of the bars (131) of the mechanism (13) when a twist is made on the worm (132) in the opposite direction to that described previously. In this case, when the worm (132) rotates on the worm, the mobile nut (133) ascends in such a way that the bars (131) that move in solidarity with the vertical movement of the nut, fold over themselves leaving from protruding below the internal mouth (21) of the tank (2) and the assembly of the safety cap (1) of the invention can be removed from the mouth (21).
    [0081]
    [0082] It is noted that to externally reinforce the neck of the mouth (21) of the tank (2), additionally the cap (1) of the invention incorporates a sleeve (15) around the neck of the tank that protects the entire outer perimeter of the mouth ( twenty-one). Between the bushing (15) and the neck of the tank (2) there is a clearance that allows the free rotation of this protection.
    [0083]
    [0084] Another detail of the invention is that, at one end, preferably of one of these flat profiles or bars (131), the cover (1) has a metal chain (15) fixed that prevents the safety plug assembly (1) from being lose or lose when this plug (1) is removed from the tank (2).
    [0085]
    [0086] Once the mechanism (13) is conveniently adjusted in the mouth (21) of the tank (2), in the central recess (122) of the cover (12) previously mentioned, a safety lock (14) is housed. This security lock (14) is cylindrical and its dimensions are such that once it is housed in the aforementioned recess (122), the clearances between them are nonexistent. It is noted that, at a midpoint of this lock (14), a flange (141) protrudes, which is housed in an internal hollow of the cavity (122), this flange (144) being actuated superiorly by means of a security key (not shown).
    [0087]
    [0088] This lock (14) is protected superiorly by plates (16) that allow the introduction of a seal through them, thus preventing unwanted extraction of the cap (1). Both plates (16) are located on the upper body of the cover (1), such that one of them rotates through an eccentric hole (161) on the exposed face of the lock (14), while the other is fixed on the surface of the cover (1) by welding or the like. Thus, as shown in Figure 8, the two plates (16) have in their vertical bodies a through hole (162), such that when both are facing, these holes coincide on the same axis by which a strap or seal can be introduced, which prevents the separation between both plates (16) and therefore the opening of the lock (14) which is located inferiorly.
    [0089]
    [0090] Therefore, when the safety plug (1) as a whole is housed in the inlet mouth (21) of a fuel tank (2), this plug (1) is fully seized to the mouth (21) both inside as externally, without the possibility of extraction and its rotation being possible on its own axis, the tank (2) being completely closed at all times.
