    "6. The timepiece according to claim 3, wherein the arm forms a wall of the mortise, the remainder of the mortise being formed in the component and the tenon being formed in the part.",
    "7. The timepiece according to claim 2, wherein the arm is formed in the part.",
    "8. The timepiece according to claim 7, wherein the arm also forms the tenon, the mortise being formed in the component.",
    "9. The timepiece according to claim 7, wherein the arm comprises the mortise, the tenon being formed in the component.",
    "10. The timepiece according to claim 7, wherein the arm forms a wall of the mortise, the remainder of the mortise being formed in the part and the tenon being formed in the component.",
    "11. The timepiece according to claim 1, wherein the part is integral with an arbour configured to rotatably mount an assembly comprising the part and the component.",
    "12. A timepiece comprising a system for assembling a part in an aperture of a component, the system for assembling comprising a system for securing the component and the part to each other on a same plane, the system for securing comprising at least one pawl device configured to lock the component and the at least one pawl device such that, once the component and the at least one pawl device are locked, the component and the part are locked in a final assembled configuration and rotate substantially integral with each other along the same plane to prevent relative movement between the component and the part, wherein the locking of the component and the part prevents the component and the part from slipping relative to one another in all directions once the component and the at least one pawl device are locked, wherein the system for securing does not comprise a clutch mechanism, and wherein, once the component and the part are locked, the component and the part are unable to be unlocked without destroying the system.",
    "13. The timepiece according to claim 12, wherein the at least one pawl device is further configured to lock the component to the part to prevent bidirectional relative rotational movement between the component and the part along the same plane.",
    "14. The timepiece according to claim 12, wherein each of said at least one pawl device comprises an elastic arm forming at least one pawl, the at least one pawl locking a mortise and tenon type assembly to prevent bidirectional relative rotational movement between the component and the part along the same plane.",
    "15. The timepiece according to claim 14, wherein the elastic arm is formed in the component.",
    "16. The timepiece according to claim 15, wherein the elastic arm also forms a tenon, a mortise being formed in the part.",
    "17. The timepiece according to claim 15, wherein the elastic arm includes a mortise, the tenon being formed in the part.",
    "18. The timepiece according to claim 15, wherein the elastic arm forms a wall of a mortise, the remainder of the mortise being formed in the component and a tenon being formed in the part.",
    "19. The timepiece according to claim 14, wherein the elastic arm is formed in the part.",
    "20. The timepiece according to claim 19, wherein the elastic arm also forms a tenon, a mortise being formed in the component.",
    "21. A timepiece comprising a system for assembling a part in an aperture of a component, the system for assembling comprising a system for securing the component and the part to each other in a same plane, the system for securing comprising at least one pawl device configured to lock the component and the part such that, once the component and the part are locked, the component and the part are locked in a final assembled configuration and move integrally with each other, wherein the locking of the component and the part prevents the component and the part from slipping relative to one another in all directions once the component and the part are locked, wherein the system for securing does not comprise a clutch mechanism, wherein the part has at least one stop and at least one mortise and at least one ramp connecting the at least one stop with the at least one mortise and the component has the at least one pawl and a tenon on each of the at least one pawl, and wherein the part and the component are rotatable relative to one another until the tenon of the component is stopped by the stop of the part and then they rotate together, and wherein the part and the component are rotatable relative to one another until the tenon of the component is locked in the mortise of the part to move integrally with each other."

  "description_excerpt": "This application claims priority from European Patent Application No. 11152202.5 filed Jan. 26, 2011, the entire disclosure of which is incorporated herein by reference.\n\nThe invention relates to a pawl lock assembly system and more specifically an assembly system of this type allowing the use of fragile material, i.e. which has no usable plastic domain.\n\nCurrent assemblies including a component made of fragile material such as silicon are generally secured by bonding. This type of operation requires extremely delicate application which makes it expensive.\n\nIt is an object of the present invention to overcome all or part of the aforementioned drawbacks, by providing a securing system that does not increase the thickness of the respective members and can be applied to fragile materials.\n\nThe invention therefore relates to a system of assembling a part in the aperture of a component, characterized in that it includes a system of securing the part and the component to each other which includes at least one pawl device intended to make the part and the component move integrally with each other.\n\nThe invention thus advantageously allows two elements to be secured to each other in the same plane, i.e. without any increase in the thickness of the elements, and without any plastic deformation which could, depending upon the nature of the materials, potentially be destructive.\n\nIn accordance with other advantageous features of the invention:\n\nFinally, the invention relates to a timepiece, characterized in that it includes an assembly system according to any of the preceding variants.",
