Description

BRIEF DESCRIPTION OF THE FIGURES

(1) The invention will be described in more detail below using the appended drawings, given by way of non-limiting examples, wherein:

(2) FIGS. 1A to 1C illustrate an embodiment of a system (100) for fastening and/or extracting a dial (190) in a fastening position (101), and

(3) FIGS. 2A-2C show an embodiment of a system (100) for fastening and/or extracting a dial (190) in an extraction position (102).

DETAILED DESCRIPTION OF THE INVENTION

(4) The present invention allows, despite the limited space available, access to some parts which are difficult to access.

(5) The present invention is in the form of a fastening and or extraction system 100 for a dial 190, preferably of a dial 190. This system comprises a holding surface 111 and an extraction surface 112. It is these surfaces which will allow said dial to be held against a support 195 or extracted from the support 195.

(6) Indeed, the dial 190 can be disposed on the support 195 and preferably on a first face 196 of the support 195 just like the movable organ 110. According to the embodiments, the support 195 may comprise a second surface or a second face, in particular opposite to the first surface, on which the movable organ 110 can be disposed so that the dial 190 and the movable organ 110 hold each other on either side of the support 195.

(7) As shown in FIGS. 1A and 1B, the dial 190 comprises 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 190 away from the support 195.

(8) The system 100 may comprise a movable organ 110 configured to displace or be displaced between a fastening position 101 and an extraction position 102. This movable organ 110 may take the shape of a lever 110 configured to pivot about a pivot axis 116 between the fastening position 101 and the extraction position 102. The holding surface 111 and/or the extraction surface 112 may be located on this same movable organ 110. Indeed, according to one embodiment shown in FIGS. 1A-2C, the movable 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 respectively disposed so that the holding arm 116 and extraction arm 117 allow the holding and extraction of the dial 190.

(9) This holding surface 111 may be facing the extraction surface 112, preferably, the normal to the holding, surface 111 is parallel and/or coaxial to the normal of the extraction surface 112 so that it/they can hold and/or extract the dial 190 respectively when the movable organ 110 displaces between the two positions and preferably between the fastening position 101 and the extraction position 102.

(10) Preferably, and as can be seen in FIGS. 1A-2C, the holding surface can be configured to conform to the holding portion 191 and the extraction surface 112 can be configured to conform to the extraction portion 192.

(11) This holding surface 111 is configured to cooperate with the holding portion 191 so as to bring the dial 190 against the support 196 when the movable organ 110 displaces or is displaced between the fastening position and the extraction position 102, which allows to fasten the dial 190 by means of the movable organ 110 to the support 195 and preferably to the first face 196 of the support 195. Indeed, when the movable organ 110 displaces or is displaced from the extraction position 102 to the fastening position 101, the holding surface 111 contacts, the holding portion 191 and presses or preferably brings the dial 190 against the support 195, as can be seen in FIGS. 1A and 1B. This allows the user to bring the dial 190 by means of the movable organ 110 against the support 195, without having to assemble or reassemble the peripheral parts necessary to hold the movement.

(12) The extraction surface 112, in turn, is configured to cooperate with the extraction portion 192 so as to move the dial 190 away from the support 195 when the movable organ 110 displaces or is displaced between the fastening position 101 and the extraction position 102, which allows the dial 190 to be moved away. Indeed, when the movable organ 110 displaces or is displaced from the fastening position 101 to the extraction, position 102 the extraction surface 112 contacts the extraction portion 192 and pushes or preferably moves away the dial 190 from the support 195, as can be seen in FIGS. 2A and 2B. This allows the user to move the dial 190 away by means of the movable organ 110 without having to disassemble other parts that would be connected to the movement.

(13) As mentioned above, the movable organ 110 can take the shape of a lever 110 pivoting about the pivot axis 115 between the fastening position 101 and the extraction position 102. This pivoting is induced by a movable stop 118 which allows the displacement of the movable organ 110 between the fastening position 101 and the extraction position 102.

(14) Indeed, like the example shown in FIGS. 1A, and 2A or 1B and 2B, the movable stop 118, shown in an oblong shape, comprises a centre of rotation about which the movable stop 118 can rotate. To this is added a proximal end of rounded shape so as to be in the proximity of the periphery of the support 195 and close to the centre of rotation, and a distal end distant from the centre of rotation and configured to be in contact with the movable organ 110 and to displace the movable organ 110 between the fastening position the extraction position 102 and preferably from the fastening position 101 to the extraction position 102.

(15) The displacement of the movable organ 110, from the extraction position 102 to the fastening position 101, may not take place when the movable stop 118 returns to its main position which corresponds to the fastening position 101 for the movable organ 110 due to the possible frictional force exerted by the support on the movable organ 110. This is why the system 100 can comprise a return element 119, according to the embodiments, which can be elastically deformed and being configured to displace the movable organ 110 between the fastening position 101 and the extraction position 102 and preferably to displace the movable organ 110 from the extraction position 102 to the fastening position 101 so as to press the movable organ in the holding position, that is to say the fastening position 101.

(16) This return element 119 may be totally or partially housed in the movable organ 110 or, according to one embodiment, the movable organ 110 may comprise a groove 109 configured to totally or partially house the return element 119 so as to reduce the bulk of the return element 119 in the fastening and/or extraction system 100.
