[0027] The present invention will be well understood and its advantages will also emerge in the light of the description which follows, given solely by way of non-limiting example and made with reference to the appended figures, in which identical reference signs correspond to structurally and / or functionally identical or similar elements. Brief description of the figures

[0028] The invention will be described below in more detail with the aid of the appended drawings, given as non-limiting examples, in which: THE Figures 1A to 1C illustrate an embodiment of a fixing and / or extraction system (100) for a dial (190) in a fixing position (101), and The Figures 2A-2Cdisclose an embodiment of a fixing and / or extraction system (100) for a dial (190) in an extraction position (102). Detailed description of the invention

[0029] The present invention allows, despite a limited space available, access to certain parts that are difficult to access.

[0030] The present invention is in the form of a system 100 fixing and / or extraction for a dial 190, preferably a dial 190. This system includes a holding surface 111 and an extraction surface 112. These are the surfaces that will allow the dial to be held against a support 195 or extract from the support 195.

[0031] In fact, the dial 190 can be placed on the support 195 and preferably on a first side 196 of the support 195 just like the moving organ 110.Depending on the embodiments, the support 195 may comprise a second surface or a second face, in particular opposite the first surface, on which the movable member 110 can be arranged so that the dial 190 and the moving organ 110 maintain each other on both sides of the support 195.

[0032] As shown in the Figures 1A and 1B , the dial 190 includes a holding portion 191 configured to bring the dial 190 against the support 195 and / or an extraction portion 192 configured to move the dial away 190 of the support 195.

[0033] The system 100 may include a moving part 110 configured to move or be moved between a fixing position 101 and an extraction position 102. This mobile organ 110 can take the form of a seesaw110 configured to pivot about a pivot axis 115 between the fixing position 101 and the extraction position 102. On this same moving organ 110 can or can be the holding surface 111 and / or the extraction surface 112. Indeed, according to an embodiment shown in the Figures 1A-2C , the moving organ 110 may include a holding arm 116 and an extraction arm 117 on which the holding surface 111 and the extraction surface 112 are arranged respectively so that the holding arm 116 and the extraction arm 117 allow the dial to be held and extracted 190.

[0034] This holding surface 111 may be opposite the extraction surface 112, preferably, the normal to the holding surface 111is parallel and / or coaxial to the normal of the extraction surface 112 so that it can hold and / or extract the dial 190 respectively when the moving organ 110 moves between the two positions and preferably between the fixing position 101 and the extraction position 102.

[0035] Preferably, and as can be observed on the Figures 1A-2C , the holding surface 111 can be configured to fit the holding portion 191 and the extraction surface 112 can be configured to fit the extraction portion 192.

[0036] This holding surface 111 is configured to cooperate with the holding portion 191 so as to bring the dial 190 against the support 195 when the moving organ 110 moves or is moved between the fixing position 101and the extraction position 102, which makes it possible to fix the dial 190 through the moving organ 110 to the support 195 and preferably on the first side 196 of the support 195. In fact, when the moving organ 110 moves or is moved from the extraction position 102 to the fixing position 101, the holding surface 111 comes into contact with the holding portion 191 and plate or preferably brings the dial 190 against the support 195, as can be seen on the Figures 1A and 1B . This allows the user to bring the dial 190 through the moving organ 110 against the support 195, without having to assemble or reassemble the peripheral parts necessary to maintain the movement.

[0037] The extraction surface 112,as for it, is configured to cooperate with the extraction portion 192 so as to move the dial away 190 of the support 195 when the moving organ 110 moves or is moved between the fixing position 101 and the extraction position 102, which allows the dial to be moved away 190. In fact, when the moving organ 110 moves or is moved from the fixing position 101 to the extraction position 102, the extraction surface 112 comes into contact with the extraction portion 192 and pushes or preferably moves the dial away 190 of the support 195, as can be seen on the Figures 2A And 2B This allows the user to move the dial away 190 through the moving organ 110 without having to disassemble other parts that would be linked to the movement.

[0038] As mentioned earlier, the moving organ 110 can take the form of a seesaw 110 pivoting around the pivot axis 115 between the fixing position 101 and the extraction position 102. This pivoting is induced by a movable stop 118 which allows the movement of the moving part 110 between the fixing position 101 and the extraction position 102.

[0039] Indeed, as the example shown on the Figures 1A And 2A Or 1B And 2B , the movable stop 118, represented in an oblong shape, includes a center of rotation around which the movable stop 118 can rotate. In addition, there is a rounded proximal end so as to be close to the periphery of the support 195and close to the center of rotation, and a distal end distant from the center of rotation and configured to be in contact with the movable member 110 and to move the moving part 110 between the fixing position 101 and the extraction position 102 and preferably the fixing position 101 to the extraction position 102.

[0040] The movement of the moving part 110, from the extraction position 102 to the fixing position 101, may not be realized when the movable stop 118 returns to its main position which corresponds to the fixation position 101 for the moving organ 110 due to the possible frictional force exerted by the support on the moving part 110. This is why the system 100 may include a reminder element 119,according to the embodiments, capable of elastically deforming and being configured to move the movable member 110 between the fixing position 101 and the extraction position 102 and preferably to move the moving part 110 from the extraction position 102 to the fixing position 101 so as to place the movable member in the holding position, i.e. the fixing position 101.

[0041] This reminder element 119 can be housed totally or partially in the moving part 110 or, according to one embodiment, the movable member 110 may include a groove 109 configured to fully or partially accommodate the recall element 119 so as to reduce the bulk volume of the recall element 119 in the system 100 fixing and / or extraction.
