    [0001] FIELD OF THE INVENTION The field of the invention is that of filter assemblies for filtering a fluid, for example fuel oil, an oil or air, circulating in particular in a motor or hydraulic equipment. 2. Prior Art Filtering assemblies generally comprise a filter body comprising a tank or shell and a lid or head. When using the filter assembly, the filter body is closed, the lid and the tank cooperating together tightly to close the filter body. The filter body is configured to house a filter cartridge. When maintaining the filter assembly, the filter cartridge is generally changed after opening the filter body. To ensure the closure of the filter body during the maintenance operation or during the installation of the filter assembly, an additional locking system of the filter body can be provided to secure the closure of the filter body. and / or to ensure its sealing by reinforcing for example the clamping between the tank and the lid.
    [0002] During a maintenance operation, the locking system is unlocked. A disadvantage of such a locking system is that it can interfere with the working environment of the operator during the maintenance of the filter assembly, and sometimes even the closure of the filter body after maintenance. 3. Objectives of the invention The invention aims to provide a filtering set whose maintenance is fast and secure.
    [0003] In particular, the object of the invention is, according to at least one embodiment, to provide such a filtering assembly which makes it possible to release the working environment of the operator during a maintenance operation. Another object of the invention is, according to at least one embodiment, to provide such a filtering assembly which makes it possible to ensure that, when closing the filter body after a maintenance operation, the locking system is correctly positioned to allow effective locking of the filter body. 4. PRESENTATION OF THE INVENTION In order to solve all or part of these objectives, the invention proposes a filtering assembly for filtering a fluid flowing in particular in a motor or hydraulic equipment, comprising: a filter body comprising a tank and a lid , the filter body being adapted to house a filter cartridge, at least one locking system of the filter body, movable between a locking position and an unlocking position. According to the invention, the filtering assembly comprises means for holding the locking system in the unlocking position. The holding means thus allow the reversible connection of the locking system. Thanks to the invention, there are means for preventing the locking system from interfering with the environment of the operator during a particular maintenance operation or when setting up the filter assembly. Thus, the operator can, thanks to the invention, use the holding means of the locking system for example after unlocking to fix it. Once the maintenance operation or the implementation of the filtering set performed, the operator can for example disengage the locking system holding means after closing the filter body to lock the filter assembly. When setting up or the maintenance operation, the operator will not have been bothered by the locking system or systems. Furthermore, thanks to the invention, when closing the filter body after the maintenance or installation operation, the operator is assured that the locking system will not get stuck in the gap between the tank and lid and impede the closing of the filter body, or even deteriorate the closure of the filter assembly.
    [0004] Advantageously, the holding means are configured to allow the operation of securing or detaching the locking system with the holding means with one hand and without the need for tools.
    [0005] The holding means cooperate for example with the latching system and / or friction, mechanical stop, fixed or removable stop. An advantage of such holding means is to make it possible to secure the locking system easily and also to make it easy to separate it, in particular with one hand and / or without tools.
    [0006] The locking system may comprise at least one actuating member and a locking member. The actuating member, integral with the lid or the tank, for example, is configured to allow the setting in the locking position and the unlocking of the locking element.

DESCRIPTION OF PARTICULAR EMBODIMENTS FIGS. 1 to 3 show a filter assembly 1 for filtering a fluid flowing for example in a motor or hydraulic equipment. The fluid may for example consist of an oil or fuel.
    [0009] The filter assembly 1 comprises a filter body 2 comprising a lid 3 and a tank 4 configured to cooperate together to allow the closure of the body of the filter 2, in particular when using the filter assembly 1, and to allow the opening of the filter body 2 during a maintenance operation for example.
    [0010] The filter body 2 is designed to house a generally removable filter cartridge 35, partially visible in FIG. 3, whose function is to filter the fluid. The filter assembly 1 further comprises at least one locking system 5 of the filter body 2, in particular several locking systems 5, as in the illustrated example where there are five in number. Each locking system 5 is movable between a locking position, visible in Figure 1 and also in Figure 3, and an unlocking position, visible in Figure 2. According to the invention, the filter assembly 1 comprises holding means 8 of the locking system in the unlocking position, as will be described below. In the example illustrated in Figures 3 to 5, the locking system 5 comprises, as visible, an actuating member 6 and a locking member 7 interconnected by a mechanical joint, in this example, by a toggle joint 9 The actuating member 6 is integral in this example of the lid 3, but it could be integral with the tank 4 without departing from the scope of the invention. In this example also, the actuating member 6 is configured to allow tensioning and holding in the locking position of the locking element 7, and conversely the passage in the unlocked position of the locking element 7 The actuating member 6 provides these two functions, in this example, by rotation in a direction and in the opposite direction of the actuating member 6 relative to the locking element 7, as will be explained hereinafter. after. The blocking element 7 is, for its part, configured to be fixed reversibly to the tank (in another example, to the lid) to ensure the locking of the filter body 2.
    [0011] In the example shown, the locking system 5 comprises a wire including metal. In this example, the toggle joint 9 comprises a first fixed axis 10 relative to the cover 3, in this example. The actuating member 6 is at least partially movable relative to this first axis 10. In the example illustrated, an end portion 17 of the actuating member 6 forms this first axis 10. In fact, in this for example, the end portion 17, wire, is fixed on the cover 3 while being rotatable relative to the lid 3. The toggle joint 9 further comprises a second axis 30, parallel in this example to the first axis 10 and formed in this for example by an end portion 31 of the locking element 7. The locking element 7 is rotatable about this second axis 30, while the actuating member 6 is fixed relative to the second axis 30. Indeed, the wire constituting the actuating member 6 forms, around the second axis 30, as illustrated and in this example, a turn 16, in two places of the second axis 30. The two towers 16 form the connection between the actuating member 6 and the blocking member 7. The the locking element 7 also comprises a hooking portion 11 forming a hook in this example, giving the locking element 7 the ability to hook the lid, respectively the bowl, when locking in the use position of the filter assembly 1. The locking element 7 further comprises in this example, a connecting portion 12 consisting in this embodiment in two wire portions 12a and 12b, substantially parallel in this example. The actuating member 6 of the locking system comprises a gripping portion 15 for its manipulation, in rotation in one direction or in a direction opposite to the first axis 10, by an operator. The two towers 16 interconnect the gripping portion 15 and the end portion 17 of the actuating member 6. In this example, the holding means 8, formed on the cover 3, are arranged on both sides. other than one of the wire portions 12, in this case the wire portion 12b, so as to reversibly fix, in this example by friction, the wire portion 12b. In this example also, the gripping portion 15 of the actuating member 6 is narrower than the spacing between the wire portions 12a and 12b, so that the rotation of the locking member 7 relative to the actuating member 6 allows the passage of the locking element 7 from one side to another of the actuating member 6, in particular in the passage between the locking position and the unlocking position, when the blocking element 7 is secured to the holding means 8 after being detached from the tank 4. When the locking system 5 is in the locked position, the locking element 7 is hooked in the example shown in the tank 4, by example in a groove thereof, provided for this purpose. To unlock, the operator rotates the actuating member 6 about the first axis 10 in one direction. Then he picks up the blocking element 7 of the tank 4. The operator then rotates the locking element 7 around the second axis 30 and attaches it to the holding means 8 present on the lid 3, in this example. The operator can then open the filter body and then perform the maintenance operation or implementation of the filter set. The operator closes the filter body 2, without the locking system 5 is an inconvenience of his working environment, thanks to the invention.
    [0012] The operator disengages the locking element 7 from the holding means 8. Then it hooks the locking element 7 to the tank 4, by rotation of the locking element 7 around the second axis 30 and insertion, for example in the groove of the tank 4, the gripping portion 11. The operator puts in tension and blocks the locking element 7 in the locking position in particular by rotation, in an opposite direction, of the actuating member 6 around the first axis 10. FIG. 6 illustrates, in isolation, the holding means 8 on the lid (or the bowl) of the embodiment of FIGS. 4 and 5. FIGS. 7 to 9 show further examples of means holding 8 that can be used. In the example of Figure 7, the holding means 8 are two in number, on the lid 3 or the tank 4, and allow to insert a portion of wire, for example 12a or 12b snap. Indeed, as visible, the holding means 8 comprise latching lugs 20 with a certain elasticity to allow their movement in order to allow snapping, securing and disengaging the locking element 7. In the mode of embodiment of Figure 8, the holding means 8 are two in number, located on the outside of the son portions 12 and for latching the locking element 7 of the locking system 5. It should be noted that each of the means also shown in FIG. 9 is an embodiment in which the holding means 8 are arranged between the portions of threads 12 and allow the locking element to be latched. 7 of the locking system 5. Each holding means 8 comprises in this example a latching lug 20. FIG. 10 shows another example of a locking system 5 in accordance with the invention. including a blocking element 7 shaped, not wire, but plate. The plate has two opposite edges 25, which can be held snap-fit in this example by the holding means 8, two in number in this example, as illustrated. In Figure 9, the actuating member 6 is not visible. Figures 11 and 12 show another embodiment of the invention. In this embodiment of the invention, the locking system is made using metal son. The actuating member 6, in its gripping portion 15, has a width greater than that of the spacing between the son portions 12 of the locking element 7. It should also be noted that in this example the portions 12a and 12b, are not parallel but slightly converge towards the attachment portion 11. In this example, the son portions 12 of the locking element 7 are curved. At least one notch 40, in particular two notches 40 formed in this example on the cover 3 of the filter assembly 1 constitute the holding means 8. FIG. 11 illustrates the locking position in which the attachment portion 11 is fixed to a rim 41 formed in the tank 4. FIG. 12 illustrates the unlocking position with securing of the locking system 5 to the holding means 8, more specifically reversible connection, in particular by friction in this example, of the locking element 7 Another exemplary embodiment of the invention has been illustrated in FIGS. 13 to 16. In this example, the blocking element is in the form of a metal plate with one end forming the attachment part 11 coming from block in a groove 42 of the tank 4 or lid 3. The actuating member 6 comprises a plate forming the gripping portion 15 surrounded by two substantially perpendicular supports 45 to the first and second axes 10 and 30 which pass through them.
    [0013] FIG. 13 shows the locking position. By rotating the actuating member 6 in one direction, the locking member 7 is disengaged from the groove 42 and unhooked. Rotation of the locking element 7 and of the actuating member 6 in the opposite direction makes it possible to arrive in the position illustrated in FIG. 15 and to secure the locking element 7 in the holding means 8, as visible in particular in Figure 16. In this example, the holding means 8 form latching lugs 20. The supports 45 of the actuating member 6 comprise notches 46 for housing the latching lugs 20 means keeping 8.
    [0014] Figures 17 and 18 illustrate another embodiment in which it is the actuating member 6 which is reversibly secured to the holding means 8 formed in this example by notches 50 holding by friction, as visible on the 18, two portions of son 51 of the actuating member 6, the son 51 being formed in a zone connecting the towers 16 to the end portion 17. Figures 19 and 20 illustrate another embodiment of the invention. invention, wherein the locking system 5 is formed in one piece, constituting both the actuating member 6 and the blocking member 7. This locking system 5 is configured to be movable at least by rotation about a single axis 60, during the transition from the locked position to the unlocked position and to be secured to the holding means 8, and vice versa.
    [0015] The invention is not limited to the examples which have just been described. In particular, the number of constituent parts of the locking system may be distinct from one or two without departing from the scope of the invention. In the case of a pivoting of the locking system about two axes, as for example in the case of the mechanical joint comprising a toggle joint, the axes may be parallel to each other, as previously described, or not parallel to each other. The mechanical articulation between the actuating member and the locking element may take place around a single axis. Throughout the description, the terms "comprising one" and "comprising one" should be understood as being synonymous with the terms "comprising at least one" and "comprising at least one", unless the opposite is specified.
