Description

[0001] The invention relates to a cooking appliance with telescopic rails.

[0002] Cooking appliances are known which have a fixed, i.e., stationary, cooking chamber formed with the cooking appliance, in which the food can be placed in or on a cooking utensil and cooked with the cooking chamber closed. Such a cooking appliance can be, for example, an oven, a steamer, a combination oven with a steamer, and the like. Such cooking appliances with a fixed cooking chamber typically have a height of approximately 45 cm along the vertical axis, at least in Germany, although ovens with a height of approximately 60 cm are also common.

[0003] Such cooking appliances with a fixed cooking chamber have in common that they have an outer housing which essentially encloses the cooking appliance on the outside and protects its individual components and elements, as well as making them easier to handle together. Within the cooking appliance, an interior space is formed which represents the cooking chamber and is essentially enclosed by an inner housing, also referred to as a cooking chamber muffle or muffle. Between the inner housing and the outer housing, a housing space is formed as an intermediate space, in which functional elements of the cooking appliance, such as a control system or control unit, an electrical power supply and other components which serve the intended use of the cooking appliance can be arranged. In depth from the front, i.e. viewed from the user's perspective, the outer housing ora panel in the form of a furniture material or in the form of a control panel and the like together with the inner housing closes off the housing space so that the housing space is not accessible to the user.

[0004] The interior of the cooking appliance has a through-opening at the front in depth as an access opening, through which the interior of the cooking appliance is accessible to the user in order to insert cooking utensils into the interior of the cooking appliance as its cooking chamber and to arrange them there, as well as to remove cooking utensils from the interior of the cooking appliance after the food has been cooked. The access opening can be opened by the user by means of a closure element, for example in the form of a door that can be pivoted to the side, a flap that can be pivoted downwards, or the like, in order to access the interior of the cooking appliance, as described above, or to close the interior of the cooking appliance and carry out the cooking operation or process. Such a closure element can be closed or have a viewing window to allow the user a view into the closed interior of the cooking appliance.

[0005] Such cooking appliances with a fixed cooking chamber are usually designed as built-in appliances or as built-in kitchen appliances in order to be arranged with their outer casing in a space-saving manner and at a height that is easily accessible for the user along the vertical axis in kitchen furniture, such as in built-in kitchen cupboards, and to be flush with the surfaces of the other cooking appliances, drawers, doors and the like of the kitchen furniture towards the front of the user with their locking element, if necessary also with their panel (see above), which can improve the visual impression for the user. However, such cooking appliances can also be designed as individual, separate appliances that can be set up and operated, in particular, on a work surface in a kitchen unit. This can simplify flexibility of use as well as procurement and disposal.

[0006] Such cooking appliances with a heatable cooking chamber typically have so-called support grids on the inside of both side walls of the cooking chamber. These are symmetrical and usually removable for cleaning. In the simplest case, the support grids have narrow compartments running parallel to each other along their length or depth. The edges of a baking tray or similar cooking utensil can be slid in and out of these compartments. This allows the baking tray to be positioned at the appropriate height or distance from the floor of the cooking chamber for the cooking process and then removed again.

[0007] To make this more convenient, it is now common practice to attach symmetrical telescopic rails to the two support grids so that the user can pull the front pair of rail elements of a pair of telescopic rails out of the cooking chamber along the longitudinal axis towards themselves, with the two rail elements usually projecting completely beyond the front of the cooking appliance in the area in front of it. The two front rail elements are connected to a pair of rear rail elements of the pair of telescopic rails by means of a pair of middle rail elements, which are fixed to the respective support grid and can usually be removed for cleaning purposes. The user can therefore very conveniently place a baking tray or similar cooking utensil from above onto the extended pair of telescopic rails.Place the front rail elements on the baking tray and then slide the baking tray along the longitudinal axis into the cooking chamber using the telescopic rails. Once the cooking process is complete, pull it out towards you again and remove it from the telescopic rails.

[0008] Telescopic rails are disclosed in the prior art, for example in the documents DE 10 2010 021 283 A1 and EP 4 000 459 A1.

[0009] The support racks are also typically designed to be removable for cleaning purposes. The support racks are typically mounted on the two side walls of the cooking chamber, although support racks are also known that are mounted on the rear wall of the cooking chamber along the longitudinal axis at the rear end of the cooking chamber, as viewed from the user's perspective or relative to the access opening.

[0010] In any case, as the name suggests, the support racks are made of thin bars or wires, usually made of metal, in a grid-like structure. When the support rack is installed, a vertical front wire runs towards the user or the access opening, and a vertical rear wire runs parallel to this wire, facing the rear wall of the cooking chamber. The two vertical wires are permanently connected to one another by several horizontal wires of the support rack. The connection is usually made by soldering or welding. The horizontal wires run parallel and along the vertical axis, equally spaced from one another and at right angles to the two vertical wires. The horizontal wires can also be referred to as level wires.The ends of the two vertical wires can be bent at right angles to the respective side wall of the cooking chamber and designed as a holder to be inserted into openings in the respective side wall of the cooking chamber and held there in a form-fitting manner. The two support grids of a cooking appliance are designed mirror-symmetrically to each other and arranged in the cooking chamber.

[0011] Support grids are known whose vertical wires rest directly against the respective side wall, so that no gap is formed between the side wall and the vertical wire, which would allow a telescopic rail or its rear rail element to grip or enclose it for the purpose of a positive hold on the support grid or its vertical wire. In order to releasably attach the telescopic rails in pairs as a rail system to a pair of such support grids, it is therefore known to clip the telescopic rails or their rear rail elements laterally onto the vertical wires of the support grid, i.e. to hold them there in a spring-elastic, force-fitting manner.

[0012] The disadvantage for the user is that the telescopic rails or their rear rail elements have to be clipped on at least once in the rear area of ​​the cooking chamber, i.e. close to or directly in front of the rear wall of the cooking chamber. However, this area of ​​the cooking chamber can be difficult or inconvenient for the user to reach through the open access opening. Having to apply force along the transverse axis to clip the telescopic rails onto the rear area of ​​the cooking chamber can be particularly difficult or inconvenient for the user. The rear area of ​​the cooking chamber, particularly close to the ceiling, can also be difficult for the user to see, which can make fitting the telescopic rails even more difficult.

[0013] In other words, with these types of cooking appliances that feature telescopic rails that clip onto the side, the user must always work in the rear area of ​​the cooking chamber to secure the rail system. Installing and disassembling the rail systems is particularly cumbersome in this area of ​​the cooking chamber, as visibility and accessibility are significantly restricted due to the design.

[0014] The invention addresses the problem of making it easier for the user to install telescopic rails on side support grids in cooking appliances. In particular, the telescopic rails should be installed as completely as possible in the front area of ​​the support grids, i.e., in the area of ​​the open access opening. In any case, this should be as simple, space-saving, cost-effective, low-maintenance, and / or intuitive as possible. At the very least, an alternative to known cooking appliances of this type should be created.

[0015] According to the invention, this problem is solved by a cooking appliance, a telescopic rail, and a mounting element having the features of the independent claims. Advantageous embodiments and further developments of the invention are set forth in the following dependent claims.

[0016] The invention thus relates to a cooking appliance with a cooking chamber which is designed to receive at least one cooking utensil through an access opening along the longitudinal axis, with a closure element which is designed to close and open the access opening of the cooking chamber from the front, preferably by pivoting by means of a pivoting element, preferably a hinge, and with at least one pair of telescopic rails which are arranged parallel to one another at the same height along the vertical axis in the cooking chamber on a respective receiving grid and are movable along the longitudinal axis through the open access opening out of the cooking chamber.

[0017] The cooking appliance is characterized by a respective holding element which is fixedly connected to the respective telescopic rail, preferably to its rear rail element, wherein each holding element has an arcuate support surface for resting on a longitudinal section of a horizontal wire of the respective receiving grid, wherein each arcuate support surface is designed to hold the holding element movably along the longitudinal axis and positively from above on the longitudinal section of the horizontal wire of the respective receiving grid along the transverse axis and along the vertical axis.

[0018] This allows the user to place the telescopic rail to be mounted on the respective support grid or its rear, fixed rail element in the front area of ​​the cooking chamber, i.e. close to the easily visible and easily accessible open access opening of the cooking chamber, along the vertical axis from above with the curved support surface of the respective holding element onto the horizontal wire of the respective support grid, which usually has a round or cylindrical cross-section. The shape or contour of the curved support surface of the respective holding element can be selected to match the respective support grid or its horizontal wires, in particular as a semicircular contour of the curved support surface of the respective holding element to match the usually round or cylindrical cross-section of the horizontal wires of the respective support grid.

[0019] In any case, the user can easily and conveniently place the telescopic rails to be mounted with their respective mounting elements in the front area of ​​the cooking chamber onto the respective horizontal wire of the support grids and then slide them backwards into the cooking chamber. The respective telescopic rail slides along the longitudinal axis on the respective horizontal wire of the support grids and is held laterally, i.e., along the transverse axis, by the profile or contour of the curved support surface of the respective mounting element on the respective horizontal wire of the respective support grid.

[0020] Once the end of the horizontal wire of the respective support rack or movement is reached, the respective telescopic rail can be fixedly attached to the support rack in the front area of ​​the cooking chamber to secure its position. Additionally or alternatively, the respective telescopic rail can also be attached to the rear area, as described in more detail below.

[0021] According to one aspect of the invention, each support element further comprises a securing web which extends along the longitudinal axis, wherein each securing web is designed to engage behind a respective vertical rear wire of the respective receiving grid along the transverse axis when the respective telescopic rail is guided along the longitudinal axis to the end of the horizontal wire of the respective receiving grid.

[0022] Thus, at the end of the previously described assembly movement, either alone or in addition to securing the rail in the front area of ​​the cooking chamber by means of the securing bar, a hold or fixation along the transverse axis inward toward the cooking chamber can be achieved in order to securely hold the telescopic rail on the horizontal wire of the respective support grid when installed. This can be done in addition to or as an alternative to the positive hold provided by the curved support surface. If necessary, the positive hold provided by the curved support surface can be canceled and "replaced" by engaging behind it using the securing bar, as described in more detail below.

[0023] According to a further aspect of the invention, each support element further comprises a flat support surface with a run-on bevel for resting on a transverse section of the horizontal wire of the respective receiving grid, wherein each run-on bevel is designed to lift the support element along the vertical axis and to detach the arc-shaped support surface from the longitudinal section of the horizontal wire of the respective receiving grid when the respective telescopic rail is guided along the longitudinal axis to the end of the horizontal wire of the respective receiving grid, wherein each flat support surface is designed to then rest along the vertical axis from above on the transverse section of the horizontal wire of the respective receiving grid.

[0024] In this way, the positive hold by means of the curved support surface of the holding element can be released by the holding element itself at the end of the assembly movement. This can be done in this way with holding grids which are bent at the end along the transverse axis towards the side wall, which can be referred to as the transverse section of the horizontal wire of the respective holding grid. The run-on bevel can come into contact with this area of ​​the respective holding grid or its horizontal wire at the end of the assembly movement, as a result of which the curved support surface of the holding element can be lifted or lifted off the horizontal wire of the respective holding grid and thus released or released from the positive hold. Then or.At the same time, as already described, the holding element can be held laterally along the transverse axis by the securing web of the holding element, so that a continuous hold of the holding element on the respective receiving grid can be ensured.

[0025] According to a further aspect of the invention, each securing web is designed to engage behind the respective vertical rear wire of the respective support grid along the transverse axis only when the ramp raises the support element along the vertical axis and releases the curved support surface from the longitudinal section of the horizontal wire of the respective support grid. This can enable a seamless transition from one positive fit by means of the curved support surface of the support element to the other positive fit by means of the securing web of the support element, while simultaneously preventing both positive fit from acting simultaneously, which could lead to mutual interference or blockage.

[0026] According to a further aspect of the invention, each securing bar is further configured to be held in a positive-locking manner along the vertical axis by means of a securing edge located at the top along the vertical axis, directly below one or the transverse section of the horizontal wire of the respective support grid, when the respective telescopic rail is guided along the longitudinal axis to the end of the horizontal wire of the respective support grid. This can lead to a positive-locking hold upwards along the vertical axis when the assembly movement is completed. Thus, a hold can also be achieved in this direction.

[0027] According to a further aspect of the invention, each holding element further comprises a securing arch with a wire receptacle for the respective vertical rear wire of the respective receiving grid, wherein each securing arch is designed to receive the respective vertical rear wire of the respective receiving grid in a form-fitting manner in the wire receptacle along the transverse axis on both sides and along the longitudinal axis facing the access opening when the respective telescopic rail is guided along the longitudinal axis to the end of the horizontal wire of the respective receiving grid.

[0028] Accordingly, in the position at the end of the assembly movement, the vertical rear wire of the respective support grid can be grasped from three sides, which can lead to a corresponding positive, secure hold in these directions.

[0029] According to a further aspect of the invention, each securing web is formed by the side of the respective securing arch facing the side wall of the cooking chamber.

[0030] This can keep the number of elements of the support element low.

[0031] In any case, the support element can be formed in one piece, i.e., integrally, which can minimize manufacturing and assembly costs. In particular, the support element can be manufactured as a sheet metal part, for example, as a stamped part, and then bent accordingly to form the respective elements, as described above.

[0032] The invention also relates to a telescopic rail for use in a cooking appliance as described above. This allows a telescopic rail to be created to implement a cooking appliance as described above and utilize its features and advantages.

[0033] The invention also relates to a mounting element for use with a telescopic rail as described above and / or for use in a cooking appliance as described above. This allows a mounting element to be created for implementing a telescopic rail or a cooking appliance as described above and utilizing its properties and advantages.

[0034] In other words, the invention makes it possible for the rail system to be easily placed on the front of support grilles that are attached to the side wall and whose rear vertical wire is located directly on the side wall. The user can then slide it backwards over the level wire. If the rear holding bracket follows the contour of the level wire, it can be ensured that the wire does not slip off the level wire and the required distance for fixing can be maintained. Because of this guidance over the level wire, the holding bracket can be centered correctly in the rear area and connected to the vertical wire in a form-fitting manner. At the same time, a small bevel on the support surface can be used to raise the holding bracket, which allows it to be fixed not only to the right and left, but also up and down.

[0035] This allows the contour of the level wire to be accommodated, both to serve as a guide and to maintain a specific distance from the side wall of the cooking chamber. By maintaining this distance, the rear retaining bracket can be automatically positioned so that it wraps around the retaining bracket in the rear area and secures it to the right and left. The support surface of the rear retaining bracket can also be designed so that it provides a slight slope in the rear area, raising the retaining bracket to the mounting height. This also ensures secure fastening both upwards and downwards.

[0036] This means the user doesn't have to reach deep into the cooking chamber to attach the rail system in the rear area to the symmetrical rack, which is only attached to the side wall. Instead, they can simply slide it in, and the attachment is automatic. In other words, even with a rack attached to the side wall of the cooking chamber, the user can place the rail system in the front area onto the rack and position it simply by sliding it backwards.

[0037] Of course, disassembling the rail systems is just as convenient in reverse order. This means that the user only needs to work at the front when disassembling the rail system and can easily pull it out. This eliminates the need to reach into the cooking chamber and awkwardly handle the rail system from the rear.

[0038] An embodiment of the invention is shown purely schematically in the drawings and is described in more detail below. It shows Figure 1 is a perspective view of a cooking appliance according to the invention, viewed diagonally from the front and top; Figure 2 is a plan view of a telescopic rail according to the invention with a holding element according to the invention along the longitudinal axis from the rear; Figure 3 is a perspective view of a support grid of the cooking appliance of the Figure 1 with telescopic rail according to the invention in a first assembly step from diagonally front to back; Figure 4 the representation of the Figure 3 as a top view from behind; Figure 5 a perspective view of the receiving grid with telescopic rail according to the invention of the Figure 3 in a second assembly step diagonally from the front and back; Figure 6 a detailed view of the Figure 5 from the side; Figure 7 a perspective view of the receiving grid with telescopic rail according to the invention of the Figure 3in the fully assembled state diagonally from the front and back; Figure 8 a detailed view of the Figure 7 from the side; and Figure 9 the representation of the Figure 7 as a top view from behind.

[0039] The figures above are viewed in Cartesian coordinates. There is a longitudinal axis X, which can also be referred to as depth X or length X. Perpendicular to the longitudinal axis X extends a transverse axis Y, which can also be referred to as width Y. Perpendicular to both the longitudinal axis X and the transverse axis Y extends a vertical axis Z, which can also be referred to as height Z and corresponds to the direction of gravity. The longitudinal axis X and the transverse axis Y together form the horizontal X, Y, which can also be referred to as the horizontal plane X, Y.

[0040] Figure 1 a perspective view of a cooking appliance 1 according to the invention from an angle from the front above.

[0041] A cooking appliance 1 according to the invention is considered using the example of an oven 1. The oven 1 has an outer housing 10, which can also be referred to as the outer housing 10 and which essentially closes off or encloses the oven 1 to the outside. The outer housing 10 closes off along the longitudinal axis X towards the front, i.e. towards the user, in the upper area with a panel 10a. Arranged within the outer housing 10 is an inner housing 11, which can also be referred to as the inner housing 11. The inner housing 11 closes off with the outer housing 10 along the longitudinal axis X to the rear, along the vertical axis Z downwards and upwards, and along the transverse axis Y on both sides, so that an intermediate space (not shown) is formed between the outer housing 10 and the inner housing 11, which intermediate space can also be referred to as the housing space. This intermediate space represents the interior of the oven 1.

[0042] The inner housing 11 also essentially encloses an interior space 12 in which a cooking process can be carried out. For this purpose, corresponding elements (not shown) for heating the interior space 12 are arranged in the intermediate space or in the interior space 12. Accordingly, the interior space 12 can also be referred to as the cooking chamber 12.

[0043] The cooking chamber 12 is accessible to the user from the front along the longitudinal axis X through an access opening 13, which is located below the panel 10a. The access opening 13 can be closed and opened by means of a closure element 14 in the form of a flap 14. For this purpose, the flap 14 is connected to the outer casing 10 of the oven 1 by means of at least one hinge (not shown) so as to be pivotable upwards about the transverse axis Y, so that the flap 14 can be pivoted upwards away from the user to close the access opening 13, and can be pivoted downwards towards the user to release the access opening 13 and to access the cooking chamber 12, see Figure 1 .

[0044] The cooking chamber 12 has a side wall 12a on each side along the transverse axis Y, on each of which a removable support grid 15 is arranged. A telescopic rail 16 is removably attached to each support grid 15 at the same height along the vertical axis Z, which together form a pair of telescopic rails 16. The telescopic rails 16 are each formed in three parts along the longitudinal axis X, such that a front rail element 16c is connected to a rear rail element 16a of the telescopic rail 16 by means of a middle rail element 16b, wherein the rear rail element 16a is held fixedly and removably on the respective support grid 15. The pair of telescopic rails 16 can also be referred to as a rail system 16.

[0045] A cooking utensil, such as a baking tray (not shown), can be placed by the user onto the pair of telescopic rails 16 or their front rail elements 16c in order to be pushed into and pulled out of the cooking chamber 12 along the longitudinal axis X. This can make it easier for the user to insert the baking tray into and remove it from the cooking chamber 12.

[0046] Each support grid 15 has a vertical front wire 15a facing the access opening 13, parallel to which runs a vertical rear wire 15c facing the rear wall (not designated) of the cooking chamber 12. The two vertical wires 15c are connected to one another in a grid-like manner by several horizontal wires 15b, see, for example, Figure 3, wherein the vertical and horizontal wires 15a, 15b, 15c are permanently connected to one another by soldering or welding. The horizontal wires 15b can also be referred to as level wires 15b. The horizontal wires 15b can be individually connected per level, cf. Figures 3 , 5 and 7 , or in pairs, cf. Figure 1 , may be provided. In any case, the horizontal wires 15b are bent at the ends at right angles to the respective side wall 12a of the cooking chamber 12, so that each horizontal wire 15b has a longitudinal section 15ba running along the longitudinal axis X, which at the ends merges into a transverse section 15bb running along the transverse axis Y. A pair of transverse sections 15bb of a horizontal wire 15b of each receiving grid 15 is designed to be comparatively long in order to be connected to the respective side wall 12a of the cooking chamber 12 and thus to hold the receiving grid 12 to the side wall 12a.

[0047] In order to make it easier for the user to mount the telescopic rails 16 on the respective support grid 15, each telescopic rail 16 can have a holding element 17 according to the invention at its end (not designated) facing the rear wall of the cooking chamber 12, which can also be referred to as a rear holding bracket 17. Figure 2 shows a plan view of a corresponding telescopic rail 16 according to the invention with a holding element 17 according to the invention along the longitudinal axis X from behind, ie viewed from the rear wall of the cooking chamber 12.

[0048] Each support element 17 is formed in one piece as a bent sheet metal part and, on the one hand, has a region facing the cooking chamber 12 which is bent towards the side wall 12a of the cooking chamber 12 and which initially forms an arcuate support surface 17a for the longitudinal section 15ba of one of the horizontal wires 15b of the receiving grid 15. Corresponding to the cylindrical contour of the vertical and horizontal wires 15a, 15b, 15c of the receiving grid 15, the arcuate support surface 17a is correspondingly semi-arcated, so that the support element 17 with its arcuate support surface 17a can rest from above on one of the horizontal wires 15b of the receiving grid 15 along the vertical direction Z and can be held laterally along the transverse axis Y. The respective telescopic rail 16 can be guided along the longitudinal axes X by means of the holding element 17 or its curved support surface 17a.

[0049] The curved support surface 17a is followed by a horizontal, flat support surface 17b for the rear transverse section 15bb of the respective horizontal wire 15b along the longitudinal axis X, so that the support element 17 can rest on the respective horizontal wire 15b of the support grid 15. In order to lift the support element 15 together with the telescopic rail 16 and to release it from the positive hold of the curved support surface 17a, the horizontal, flat support surface 17b has a run-on slope 17c or a bevel 17c along the longitudinal axis X facing the rear wall of the cooking chamber 12.

[0050] On the other hand, the support element 17 has a U-shaped securing arc 17d facing the side wall 12a of the cooking chamber 12, which forms a wire receptacle 17e, open along the longitudinal axis X toward the rear wall of the cooking chamber 12, for the respective vertical rear wire 15c of the support grid 15. The open end of the securing arc 17d forms a securing web 17f or a fixation 17f. The upper edge of the securing arc 17d along the vertical direction Z represents a securing edge 17g for the transverse section 15bb of the respective horizontal wire 15b.

[0051] The assembly of one of the two telescopic rails 16 according to the invention of a pair of telescopic rails 16 by means of the mounting element 15 according to the invention can now be carried out as shown in the Figures 3 to 9 shown.

[0052] Figure 3 shows a perspective view of a support grid 15 of the cooking appliance 1 of the Figure 1with telescopic rail 16 according to the invention in a first assembly step diagonally from front to back. Figure 4 shows the representation of the Figure 3 as a top view from behind.

[0053] First, the telescopic rail 16 is placed by the user (not shown) in the front area of ​​the cooking chamber 12 near the open access opening 13 using the curved support surface 17a of the holding element 17 and is then pushed rearward along the longitudinal axis X toward the rear wall of the cooking chamber 12. This area of ​​the cooking chamber 12 can be referred to as the rear area 12b of the cooking chamber 12, cf. Figure 1 This can be done relatively easily, conveniently, and clearly for the user.

[0054] Figure 5 shows a perspective view of the receiving grid 15 with the telescopic rail 16 according to the invention of the Figure 3 in a second assembly step diagonally from front to back. Figure 6 shows a detailed view of the Figure 5from the side.

[0055] If, at the end of the previously described movement, the holding element 17 reaches the respective rear transverse section 15bb of the respective horizontal wire 15b of the receiving grid 15, the respective run-on bevel 17c simultaneously comes into contact with the rear transverse section 15bb, whereby the holding element 17 is lifted and the curved support surface 17a is lifted or detached from the longitudinal section 15ba. Secondly, the securing web 17f of the holding element 17 now engages behind the vertical rear wire 15c of the receiving grid 15, so that from now on, the guidance or support along the transverse axis Y, which until then was provided by the curved support surface 17a, can be taken over by the securing web 17f, cf. Figure 6 .

[0056] Figure 7 shows a perspective view of the receiving grid 15 with the telescopic rail 16 according to the invention of the Figure 3in the fully assembled state diagonally from the front to the back. Figure 8 shows a detailed view of the Figure 7 from the side. Figure 9 shows the representation of the Figure 7 as a top view from behind.

[0057] During the remaining movement along the longitudinal axis X, the holding element 17 slides further with its flat support surface 17b on the rear transverse section 15bb of the horizontal wire 15b of the receiving grid 15 until the vertical rear wire 15c of the receiving grid 15 is completely received in the wire receptacle 17e of the holding element 17 and rests there. The wire receptacle 17e or the securing arch 17d of the holding element 17 thus secures or holds along the transverse axis Y in both directions and along the longitudinal axis X facing the user or the access opening 13, so that the final assembly position now reached can only be canceled by the reverse movement toward the user or the access opening 13.
