Leaktight frame for a window and a mechanical assembly provided with such a frame

1. A leaktight frame for a window and suitable for securing said window to a carrier structure, wherein the frame includes

removable distinct first and second U-shaped sealing gaskets with leaktight channel sections having continuous inner surfaces orthogonal to their length respectively suitable for being arranged on a first periphery of said window and on a second periphery of said carrier structure,

said frame being provided with removable holder means distinct from the first and second gaskets for clamping said first and second gaskets onto the window and the carrier structure, the holder means holding the first periphery in the first gasket and the second periphery in the second gasket;

wherein said first and second U-shaped gaskets each define a receiver groove, a first receiver groove of the first gasket receiving a first periphery of said window and a second receiver groove of the second gasket receiving a second periphery of said carrier structure.

2. A frame according to claim 1 , wherein said holder means comprise first and second clamping means that co-operate mutually in reversible manner to clamp firstly said first gasket to said window, and secondly said second gasket to said carrier structure.

3. A frame according to claim 2 , wherein said first and second clamping means are paired.

4. A frame according to claim 2 , wherein each clamping means is provided with a rigid web and with associated fastener means, including a first web and first fastener means for the first clamping means, and a second web and second fastener means for the second clamping means, said first fastener means cooperating with said second fastener means so that the holder means clamp firstly said first gasket to said window and secondly said second gasket to said carrier structure.

5. A frame according to claim 4 , wherein each of the clamping means comprises a single piece.

6. A frame according to claim 4 , wherein each of the fastener means is secured in said associated web.

7. A frame according to claim 4 , wherein the fastener means and the associated web comprise respectively first and second materials (MAT 1 , MAT 2 ) that are different.

8. A frame according to claim 4 , wherein each of the fastener means has a U-shaped section so as to present a base and two side branches, said base of the fastener means being secured to the associated web.

9. A frame according to claim 8 , wherein said branches are provided with retaining means, the first retaining means of the first fastener means co-operating with the second retaining means of the second fastener means to secure the first clamping means reversibly to the second clamping means.

10. A frame according to claim 1 , including disconnection means attached to the removable holder means for disconnecting the holder means.

11. A frame according to claim 10 , wherein said holder means include first and second clamping means, said disconnection means being provided with at least one traction means arranged on said first and/or second clamping means.

12. A frame according to claim 11 , wherein said traction means are connected to a zone of weakness of said first and/or second clamping means.

13. A mechanical assembly provided with a window and a carrier structure suitable for receiving said window, said mechanical assembly comprising a leaktight frame between a first periphery of said window and a second periphery of the carrier structure, wherein said frame includes

removable distinct first and second U-shaped sealing gaskets with leaktight channel sections having continuous inner surfaces orthogonal to their length respectively suitable for being arranged on a first periphery of said window and on a second periphery of said carrier structure,

said frame being provided with removable holder means distinct from the first and second gaskets for clamping said first and second gaskets onto the window and the carrier structure, the holder means holding the first periphery in the first gasket and the second periphery in the second gasket,

wherein said first gasket has a channel-section defining a first receiver groove, the first periphery of the window penetrating part of the way into the first receiver groove of the first gasket.

14. A mechanical assembly according to claim 13 , wherein said first and second gaskets project from the holder means.

15. A mechanical assembly according to claim 13 , wherein said second gasket has a channel-section defining a second receiver groove, the second periphery of the carrier structure penetrating part of the way into the second receiver groove of the second gasket.

16. A leaktight frame for a window that secures the window to a carrier structure, wherein the frame includes

first and second sealing gaskets with leaktight channel sections having continuous inner surfaces orthogonal to their length respectively arranged on a first periphery of said window and on a second periphery of said carrier structure,

removable holder means distinct from the first and second sealing gaskets for clamping said first and second gaskets onto the window and the carrier structure, the removable holder means holding the first periphery in the first gasket and the second periphery in the second gasket, thereby creating a leaktight seal between the window and the carrier structure,

wherein said first and second gaskets have a channel-section defining a receiver groove, a first receiver groove of the first gasket receiving a first periphery of said window and a second receiver groove of the second gasket receiving a second periphery of said carrier structure.
