Description

Title of the invention: Hose support for fuel dispenser Technical field to which the invention relates

[01] The present invention relates to a fuel distributor and more particularly a gas distributor for a vehicle of the LPG (Liquefied Petroleum Gas) type.

TECHNOLOGICAL BACKGROUND [02] Such a fuel dispenser comprises a structure in which is housed a fuel distribution circuit connected to a hose equipped with a gun intended to deliver fuel, such as liquefied gas, gas oil or fuel. 'gasoline, in a vehicle tank.

[03] The hose of an LPG gas distributor is connected to a gas distribution circuit via a removable (or brittle) connection.

[04] After a distribution of fuel, it happens that a motorist forgets to unhook the gun from the inlet of a vehicle tank. When the motorist inadvertently leaves with his vehicle, he drives the gun with the hose. The detachable connector disengages to separate into two parts each comprising a valve which closes automatically upon disconnection to prevent pressurized gas (25 bars) from spilling into the atmosphere. The hose of the gas distribution circuit is then disconnected from the fuel distribution circuit. This type of accident is commonly referred to as a “drive-off”. [05] The hose is conventionally hooked to an open upper part of the fuel dispenser by making a loop. This prevents the hose from resting on the ground in a cumbersome manner once the refueling operation has been completed. l [06] Document WO2018 / 097834 describes by way of example a hose support positioned at an upper part of a fuel dispenser formed by a canopy panel. The hose holder supports the hose and includes locking means for easily locking and releasing it when a user pulls on it to obtain a longer hose length when dispensing fuel.

[07] This solution is particularly interesting when it is used by a pump attendant who puts the hose back in the locking means after use.

[08] However, it is not suitable for self-service use, as motorists do not put the hose back in place each time on the locking means.

[09] In addition, this type of solution is not intended to be used as a safety device when a motorist inadvertently leaves with his vehicle while the nozzle of the gun is still hooked to the filling mouth of the fuel tank. vehicle ("drive-off").

[10] To solve this safety problem in the event of a "drive-off", there are solutions such as those of document US2016 / 0238177 disclosing a hose retractor comprising an elastic cord connecting the hose to a mast connected to the fuel distributor.

[11] The rope is connected to the hose via a disconnect means which disconnects when the vehicle leaves with the gun connected to the mouth of the tank.

[12] However, this solution is not ideal as it requires that the disconnection means release the hose before the detachable fitting disconnects to release the hose from the distribution circuit. Otherwise, there is a risk of the end of the hose disconnected from the removable connector being catapulted, posing safety problems for people around the dispenser.

[13] Document US5836361 describes another solution in which a flexible loop is connected to a movable arm in rotation by means of a disconnection means comprising a disc connected to three lugs held in tension against the disc by means of three springs. This solution is also planned so that the hose disconnects from the arm when a vehicle leaves with the gun connected to the reservoir mouth.

[14] However, this solution, which is specifically adapted to this type of mobile arm, is complex because it requires a certain flexibility in space to follow the movement of the arm in all directions and not to disconnect too early. The installation of the hose is also tricky and time-consuming because it is necessary to fine-tune the tension of the three springs.

[15] In addition, all of these solutions are intended for use of the hose outside the fuel dispenser. None of these solutions are suitable for use in a closed, narrow compartment such as a hose storage compartment.

[16] The object of the present invention is to remedy these drawbacks by providing a fuel dispenser comprising a hose support making it possible to release the hose from a fuel dispenser in complete safety when a vehicle leaves with the gun connected to the tank mouth and can be housed in a hose storage compartment.

Object of the invention

[17] The invention relates to a fuel dispenser comprising a structure in which is housed a fuel distribution circuit connected to a hose equipped with a gun intended to deliver fuel to a vehicle tank. The structure comprises an upper portion on which is mounted a hose holder comprising connection means intended to hold the hose blocked and to release it from the hose holder when traction is exerted on the hose.

[18] According to the invention, the connection means comprise a fixed part integral with the upper portion of the structure and a movable part configured to translate relative to the fixed part along the upper portion in a direction of deployment A of the flexible from a locking position of the hose to a release position of the hose when a tensile force exceeding a threshold tensile force is exerted on the hose. [19] The invention thus provides a fuel dispenser comprising a hose support making it possible to release the hose from a fuel dispenser in complete safety when a vehicle leaves with the gun connected to the mouth of the tank.

[20] The flexible hose is thus disconnected from the structure of the distributor before the removable connector disconnects, in a perfectly reproducible manner.

[21] The invention also provides a simple and suitable solution for use in a self-service station.

[22] Preferably, the hose comprises a fastening element. The fixed part and the movable part of the connection means being arranged so as to form at least one retaining housing in which is housed at least part of the fixing element. The movable part is able to translate in the direction of deployment A between the locking position of the hose in which the retaining housing is closed to block the fixing element and the release position of the hose in which the retaining housing is open. to release the fastening element.

[23] According to a possible embodiment, the connection means comprise two retaining housings. The hose attachment element is a rod inserted into a connecting element connected to a nut attached to the hose. The fastening element has two opposite fastening ends, each intended to be housed in one of the two retaining housings.

[24] Advantageously, the fixed and mobile parts have an elongated shape and extend along the upper portion of the structure in the direction of deployment A. The fixed and mobile parts each have two parallel side walls. The connection means comprise sliding means, allowing the movable part to slide along the fixed part.

[25] According to one possible embodiment, the side walls of the fixed part each comprise a groove extending longitudinally along the side walls. Each groove has a closed end and an opening opposite the closed end. Each side wall of the movable part comprises an opening cooperating with a groove of the fixed part to form one of the two retaining housings in which one of the ends is blocked. fixing the fastening element in the flexible locking position. The openings of the movable part are aligned with the openings of the fixed part in the flexible release position.

[26] Advantageously, the connection means comprise elastic means intended to return the movable part of the connection means towards a direction opposite to the direction of deployment A in order to keep the hose in the locking position.

[27] According to one possible embodiment, the elastic means comprise a spring comprising a first end fixed to the upper portion of the structure and a second end fixed to a rear part of the movable part of the connection means.

[28] Preferably, the flexible support comprises tensioning means making it possible to put in tension the elastic means to move the movable part in the direction of deployment A in order to align the openings of the movable part with the grooves of the fixed part to allow the insertion of the fixing element in the two retaining housings during the assembly of the flexible on the connection means of the flexible support.

[29] According to one possible embodiment, the tensioning means comprise a movable screw in rotation having one end connected to the upper portion of the structure and a threaded element fixed to the front part of the movable part. The rotation of the screw in the threaded element causes the movement of the movable part relative to the fixed part.

[30] After unhooking the hose or during the first assembly, the hose can be connected quickly and easily to the hose support thanks to the tensioning means. Installation is completed in just two steps.

[31] It suffices only to screw the threaded element and then insert the fixing element into the two retaining housings of the connection means and the connecting element of the hose nut.

[32] It is not necessary to adjust the tension of the tensioning means which is predefined.

[33] Preferably, the structure comprises a hose storage compartment intended to at least partially house the hose after an operation. fuel distribution. The upper portion of the structure is formed by an upper panel delimiting the flexible storage compartment and on which is mounted at least one flexible support.

[34] The invention provides a compact solution, ideally suited for use in a narrow hose storage compartment of an LPG type fuel dispenser.

[35] In fact, the hose support only allows translation in a direction of deployment A of the hose, that is to say parallel to the side cover panels of the distributor. This prevents movements in other directions which could contribute to friction of the hose against the structure of the distributor when the hose is unhooked and the risk of the hose nut jamming in the edges of the casing panels delimiting the passage. flexible. The unhooking of the hose is thus guided in complete safety in a small space which can include several hose supports. Description of figures

Detailed description of the invention

[44] Figure 1 shows a fuel distributor 1 and more precisely an LPG gas distributor comprising a structure 2 in which is housed a fuel distribution circuit and more particularly gas (not shown).

[45] In this example, the structure 2 of the fuel dispenser 1 comprises a hydraulic compartment 32 integrating the fuel distribution circuit and a hose storage compartment 33 in which the hose 3 is at least partially housed after a distribution operation. in fuel, as shown in Figure 1.

[46] The hose 3 comprises a first end 34 connected to a gun 4 intended to deliver fuel to a vehicle tank.

[47] A second end 35 of the hose 3 is connected to a gas distribution circuit via a removable (or brittle) connector 36. The removable connector 36 includes a valve which closes automatically upon disconnection of the removable connector 36 in the event of a "drive-off" to prevent pressurized gas (25 bars) from spilling into the atmosphere.

[48] The fuel dispenser 1 comprises a hose support 5 positioned at an upper portion 7 of the structure 2. In this example, the upper portion 7 corresponds to an upper panel 7 of the hose storage compartment 33.

[49] The hose storage compartment 33 is also delimited by two side panels 37 (a single side panel is shown for simplicity). The hose storage compartment 33 comprises two flanges 38 defining a passage 39 for the hose 3. [50] The hose support 5 comprises connection (or connection / disconnection) means 6 intended to keep the hose 3 blocked on the hose support 5 in normal use and to release it from the hose support 5 when 'significant traction is exerted on the hose 3, that is to say when a threshold tensile force is reached, exceeding a tensile force intended for normal use of the hose 3, that is to say a traction performed by a user.

[51] Such a threshold tractive force is accidentally reached when a vehicle leaves with the gun still connected to the fuel tank mouth ("drive-off") after a fuel dispensing operation.

[52] According to the invention as illustrated in Figures 2 to 7, the connection means 6 comprise a fixed part 8 integral with the upper portion 7 of the structure 2 and a movable part 9 configured to translate relative to the fixed part 8 along the upper portion 7 following a direction of deployment A of the hose 3 from a blocking position of the hose 3 to a release position of the hose 3 when the threshold tensile force is reached.

[53] The direction of deployment A corresponds to the direction in which the hose 3 is deployed by a user to distribute fuel.

[54] The direction of deployment A is substantially parallel to the side panels 37 of the hose storage compartment 33.

[55] Figures 2, 3 and 5 to 7 show an upper portion 7 comprising two flexible supports 5, only one of which is shown completely for simplicity.

[56] As illustrated in Figure 3, a nut 25 is fixed to the flexible 3 by surrounding the latter. The nut 25 has an oblong or oval shape so as to slide along the structure 2 in the event of the nut 25 being unhooked in order to avoid its blocking. The nut 25 comprises two parts 25a, 25b fixed against each other by tightening the hose 3. The nut 25 is made of polymer.

[57] A connecting element 24 is fixed to the nut 25 by means of a screw 40 and more precisely to an upper part 25a of the nut 25. The connecting element 24 has a cylindrical shape of suitable dimension to engage in the movable part 9. Other shapes are possible.

[58] The connecting element 24 includes a hole 41 allowing the insertion of a fastening element 10. In this example, the fastening element 10 is a rod

10 removable, protruding from the two flat faces 24a, 24b of the connecting element 24.

[59] In general, the fixed part 8 and the movable part 9 of the connection means 6 are arranged so as to form at least one retaining housing

11 in which is housed at least part of the fixing element 10. The retaining housing 11 is in the form of an orifice.

[60] The movable part 9 is able to translate in the direction of deployment A between the locking position of the hose 3 in which the holding housing

11 is closed at its periphery to block the fixing element 10 and the release position of the hose 3 in which the retaining housing 11 is open at its periphery to release the fixing element 10.

[61] In the examples of Figures 1 to 7, the connection means 6 of the hose support 5 comprise two retaining housings 11.

[62] The fastening element 10 has two opposing fastening ends 26a, 26b, each intended to fit into one of the two retaining housings 11.

[63] The fixed 8 and mobile 9 parts are formed of two respective rails 8, 9 extending along the upper portion 7 of the structure 2 in the direction of deployment A. The rails 8, 9 are metal or polymer .

[64] The fixed part 8 comprises two parallel side walls 12. The mobile part 9 comprises two parallel side walls 13 connected by a central wall 42.

[65] The fixed part 8 is formed directly in the upper portion or panel 7 of the structure 2 by cutting the panel and folding two portions to form the two parallel side walls 12.

[66] The movable part 9 is housed in the fixed part 8 so that the side walls 13 of the movable part 9 slide along the parallel side walls

12 of the fixed part 8. [67] The two flat faces 24a, 24b of the connecting element 24 are positioned opposite the side walls 13 of the mobile part 9.

[68] The length of the connecting element 24, that is to say the distance between the two flat faces 24a, 24b, is less than the distance between the two side walls 13 of the mobile part 9.

[69] The connection means 6 comprise sliding means 14,

15 allowing the mobile part 9 to translate and more precisely to slide along and inside the fixed part 8.

[70] The side walls 13 of the movable part 9 slide along the side walls 12 of the fixed part 8.

[71] The side walls 12 of the fixed part 8 each comprise a groove

16 extending longitudinally along the side walls 12 substantially in the direction of deployment A. The two grooves 16 are facing each other.

[72] Each groove 16 has a closed end 17, positioned on the side opposite the gun 4, and an opening 18 opposite the closed end 17.

[73] Each side wall 13 of the movable part 9 comprises an opening 19 cooperating with a groove 16 of the fixed part 8 to form one of the two retaining housings 11 in which is blocked one of the fixing ends 26a, 26b of the fixing element 10 when the hose 3 is in the locking position of the hose 3.

[74] In the release position of the flexible 3, the openings 19 of the movable part 9 are aligned with the openings 18 of the fixed part 8 to allow the fixing element 10 to be released. The two retaining housings 11 are then open. at their periphery.

[75] Figure 4 shows schematically a detailed cross section of the fastening element 10 engaged in the connection means 6 of the hose support 5.

[76] The two fixing ends 26a, 26b of the fixing element 10 each have a groove 43, delimited by two walls 47 forming a stopper allowing the side walls 12 of the fixed part 8 to be locked in the two grooves 16. [77] The two fixing ends 26a, 26b of the fixing element 10 are clamped against an edge 44 delimiting the openings 19 of the movable part 9 and a front edge 45 of the closed end 17 of the fixed part 8, as shown in figure 5.

[78] More specifically, the edge 44 delimiting the openings 19 of the movable part 9 bears against a central and cylindrical part 46 of the fixing element 10.

[79] The connection means 6 comprise elastic means 20 intended to return the movable part 9 to a direction opposite to the direction of deployment A, thanks to a return force opposite to this direction of deployment A, to maintain the flexible 3 in the locked position.

[80] The elastic means 20 are positioned on the side opposite the gun 4.

[81] The elastic means 20 make it possible to keep the fixing element 10 locked against the edge 44 delimiting the openings 19 of the movable part 9 on the one hand and the front edge 45 of the closed end 17 of the fixed part 8 on the other hand.

[82] The return force of the elastic means 20 determines the threshold tensile force to be exceeded so that the movable part 9 moves in the direction of deployment A. This threshold is reached when a vehicle drives the gun and pulls on the hose. . This restoring force is defined so that a user pulling on the hose 3 to use fuel does not reach it.

[83] According to the embodiment of Figures 2 to 7, the elastic means 20 comprise a spring 20 having a first end 21 fixed to the upper portion 7 of the structure 2 and a second end 22 fixed to a rear part 23 of the movable part 9 of the connection means 6 and more precisely on the central wall 42. The rear part 23 is positioned on the side opposite the gun 4.

[84] Other elastic means 20 are possible. Means equivalent to elastic means 20 are also possible such as magnetic retaining means.

[85] The sliding means 14, 15 allowing the movable part 9 to slide and slide in the fixed part 8 and also to limit the stroke of the movable part 9. They also make it possible to keep the movable part 9 integral with the fixed part 8.

[86] The sliding means 14, 15 comprise a first sliding means 14 comprising a slot 48 in the central wall 42 of the movable part 9, as shown in FIG. 6. A washer 49 is fixed to a threaded rod 50 it -even fixed to the upper portion 7 of the structure 2, as shown in FIG. 5. The washer 49 is retained by a nut 51. The threaded rod 50 passes through the slot 48 of the central wall 42 of the movable part 9. The central wall 42 of the movable part 9 can slide between the upper portion 7 of the structure 2 and the washer 49.

[87] The sliding means 14, 15 comprise a second sliding means 15, remote from the first sliding means 14, comprising a transverse rod 52 fixed to the two side walls 12 of the fixed part 8, as shown in FIG. 7.

[88] The second sliding means 15 comprises two recesses 53 formed in the two side walls 13 of the movable part 9.

[89] The transverse rod 52 passes through the two recesses 53 so that the transverse rod 52 slides inside the two recesses 53.

[90] Other variants of sliding means are also possible such as two first sliding means 14 distant.

[91] The flexible support 5 comprises tensioning means 27 making it possible to put in tension the elastic means 20 to move the movable part 9 in the direction of deployment A in order to align the openings 19 of the movable part 9 with the grooves 16 of the fixed part 8 to allow the insertion of the fixing element 10 in the two retaining housings 11 when mounting the hose 3 on the connection means 6 of the hose support 5.

[92] The tensioning means 27 are positioned at a front part 28 of the movable part 9, on the side of the gun 4. The tensioning means 27 comprise a screw 29 movable in rotation and having one end 30 connected to the upper portion 7 of the structure 2 by a tab 54, and a threaded element 31 fixed to the front part 28 of the mobile part 9 by another tab 55. [93] The two tabs 54, 55 are facing one another and include an orifice for the passage of the screw 29.

[94] The rotation of the screw 29 in the threaded element 31 causes the movement of the movable part 9 relative to the fixed part 8.

[95] Other alternatives are possible such as a fixed screw cooperating with a movable threaded rod (not shown).

[96] A cover 56 is provided to hide the tensioning means 27, as illustrated in Figures 3 and 5. The cover 56 comprises a front end 57 folded to be fixed in a simple manner on the transverse rod 52 of the means of sliding 14, 15. A rear wall 58 of the cover 56 is fixed to the tab 54 of the upper portion 7 of the structure 2 by a plastic clip 59 or a screw.

[97] The following describes a method of installing hose 3 on hose support 5.

[98] In the condition of use of the fuel dispenser 1, as illustrated in Figure 2, the screw 29 of the tensioning means 27 is not present. It is screwed into the threaded element 31 for mounting the hose 3 on the hose support 5, during the first installation or after an accidental release of the hose still attached to a vehicle to put a new hose back in place on the hose support. flexible 5.

[99] When mounting the hose 3 on the hose support 5, during the first installation, the screw 29 is introduced into the threaded element 31, as illustrated in figure 6. The movable part 9 has been moved towards the spring 20 because pulled by the latter. The first sliding means 14 blocks the travel of the movable part 9.

[100] As illustrated in Figure 7, the screwing of the screw 29 in the threaded element 31 causes the movement of the movable part 9 in a direction opposite to the spring 20, that is to say in the direction of deployment A, by tensioning the latter, until the openings 19 of the movable part 9 are aligned with the grooves 16 of the fixed part 8.

[101] The transverse rod 52 of the sliding means 14, 15 is introduced into the two recesses 53 of the movable part 9. [102] The following steps are carried out during the first installation of the hose 3 on the hose support 5 or during a repair after unhooking.

[103] The connecting element 24 which is connected to the hose 3 is then inserted into the movable part 9 so as to align its orifice 41 with the openings 19 of the movable part 9 and the grooves 16 of the fixed part 8.

[104] The fixing element 10 is then inserted, by its first end 26a, into the openings 19 of the movable part 9, the grooves 16 of the fixed part 8 and the orifice 41 of the connecting element 24.

[105] The fastener 10 has a first fastening end 26a and a second fastening end 26b of larger diameter than the first fastening end 26a. Thus, the first fixing end 26a has a diameter small enough to allow its insertion into the openings 19 of the movable part 9, the grooves 16 of the fixed part 8 and the orifice 41 of the connecting element 24 during assembly. from the hose 3 to the hose holder 5.

[106] The second fixing end 26b has a larger diameter so that it has a head 60 forming a stop against the outer side of one of the side walls 12 of the fixed part 8, as illustrated in FIG. 4. This makes it possible to prevent the fixing element 10 from coming out of the openings 19 of the movable part 9, of the grooves 16 of the fixed part 8 and of the orifice 41 of the connecting element 24.

[107] By gravity and the weight of the hose 3, the grooves 43 of the fastener 10 are found blocked in the respective grooves 16 of the fixed part 8, the fastener 10 can no longer escape.

[108] The hose 3 is thus fixed to the hose support 5.

[109] The screw 29 of the tensioning means 27 is then unscrewed and removed. The spring 20 exerts a return force on the movable part 9, causing the locking element 10 to lock between the front edge 45 of the closed end 17 of the groove 16 and the edge 44 delimiting the openings 19 of the part. mobile 9. [110] A vehicle moves relative to the fuel distributor 1 generally in a direction B (fig. 1), secant to the direction of deployment A.

[111] When the vehicle carries a pistol 4 still attached to the mouth of its tank, a strong tension is applied to the nut 25 of the hose 3 following the direction of deployment A of the hose 3. When a threshold tensile force is exceeded , that is to say when the tensile force is greater than the return force of the spring 20, the fixing element 10 integral with the nut 25 moves and slides the movable part 9 in the direction of deployment A relative to the fixed part 8.

[112] When the openings 19 of the movable part 9 are aligned with the openings 18 of the fixed part 8, the movable part 9 is in the release position of the hose 3 and the fixing element 10 escapes from these openings 18 , 19, freeing the hose 3 from the hose holder 5.

[113] If the vehicle continues to move away from the fuel dispenser 1, the pulling force exerted on the hose 3 increases and the detachable connector 36 disconnects to release the hose 3 out of the fuel distribution circuit safely.

[114] In the example of Figures 1 to 7, the fuel distributor 1 is an LPG gas distributor comprising a hose storage compartment 33 housing two hoses 3 connected to two separate guns 4 so as to be able to refuel two vehicles of each side of the fuel dispenser 1.

[115] The upper portion 7 of the hose storage compartment 33 then comprises two hose supports 5 arranged close to one another but being offset to prevent the hoses 3 from touching each other.

[116] The movable parts 9 of the two hose supports 5 are arranged to translate in two opposite directions relative to each other in the event that the hose 3 is carried by a vehicle, their direction of deployment A being opposite. These translations in opposite but parallel directions of deployment A make it possible to optimize the space in the hose storage compartment 33 and to avoid friction between the hoses 3.
