[0047] [Fig. 1] to 3 partially illustrate an article 1, here leather goods, provided with a first part 2 and a second part 3 forming a support and mechanically secured to the first part 2 using a fixing screw 4.

[0048] Alternatively, the item may be a piece of jewelry, cosmetics, or furniture rather than a piece of leather goods.

[0049] Alternatively, the support may not be formed by a second part of the article, but rather be separate from this article.

[0050] In Figures 1 and 2, the screw 4 is introduced into a first orifice 5 made in the first part 2 and is provided with a head 7 which comes flush with a first external surface 6 of this first part 2.

[0051] As visible in [Fig.2], the first orifice 5 has a diameter slightly larger than the area of ​​the outermost head 7 and which is flush with the first surface external 6, so that a radial clearance 28 is provided for the assembly and disassembly of the screw 4.

[0052] In [Fig. 3], an ornamental element 9, here formed by a precious stone, is affixed to the head 7 of the screw 4 and extends in projection from the external surface 6 of the first part 2.

[0053] The decorative element 9 is mechanically secured to the head 7, for example by gluing or crimping or even welding.

[0054] Alternatively, the decorative element may be a precious metal and / or may be made in one piece with the head of the screw.

[0055] Figures 4 and 5 show the disassembled article 1, with its first part 2 and second part 3 at a distance from each other, the screw 4 as well as an actuating tool 10 for the screw 4.

[0056] In the illustrated example, the first part 2 of the article 1 comprises a first external face 11 defining its first external surface 6, and a first internal face 12 opposite its first external face 11.

[0057] The first orifice 5 is arranged so as to pass through the first part 2 and open out on either side of its first external face 11 and first internal face 12.

[0058] The diameter of the first orifice 5 on the side of the first external face 11 is larger than that on the side of the first internal face 12, so that a bottom wall 13 forming a stop is provided on the side of the first internal face 12.

[0059] The first part 2 of the article 1 here further comprises pins 14 provided projecting from the first internal face 12, substantially around the first orifice 5.

[0060] In the example illustrated, the second part 3, forming the support, has a second external face 15.

[0061] The second part 3 of the article 1 is here provided with a tapped hole 16 opening onto the second external face 15.

[0062] The second part 3 is further provided with mounting orifices 17 substantially around the tapped hole 16 and which open onto the second external face 15.

[0063] The article 1 is here configured so that the first internal face 12 of the first part 2 is intended to be applied against the second external face 15 of the second part 3, with the first orifice 5 which is located opposite the tapped hole 16 and the pins 14 which are intended to be inserted into the mounting orifices 17.

[0064] The screw 4 is provided with a body 8 extending longitudinally projecting from the head 7.

[0065] In the example illustrated, the body 8 has a cylindrical shape and an external surface that is at least partially threaded.

[0066] The head 7 is here provided with an external part 18 and an internal part 19 from which the body 8 projects.

[0067] Thus, the internal part 19 is interposed between the external part 18 and the body 8.

[0068] The actuating tool 10 here comprises a gripping body 20, designed to be grasped directly or indirectly by a user, and a driving body 21 configured to transmit a torque to the fixing screw 4 when the gripping body 20 is rotated.

[0069] In particular, as explained below in more detail, it is the internal part 19 of the head 7 of the screw 4 which is configured to be stressed and driven in rotation by the drive body 10 of the actuating tool 10.

[0070] Figures 6 to 9 show in more detail the fixing screw 4, which extends from the external part 18 of its head to a distal end 30 corresponding to a free end of the at least partially threaded body 8.

[0071] In the example illustrated, the external part 18 of the head 7 has a cylindrical shape and has a first thickness.

[0072] Alternatively, the external part of the head may have a rectangular, hexagonal or triangular shape or any other shape.

[0073] The internal part 19 of the head 7 here has a second thickness which is generally identical to the first thickness.

[0074] Alternatively, the outer portion and the inner portion have different first and second thicknesses.

[0075] The internal part 19 of the head 7 extends here partially and radially beyond the external part 18 of the head 7 and is provided with notches arranged circumferentially, so as to delimit several drive sections 24.

[0076] Two drive sections 24 are thus separated by a space formed by a respective notch.

[0077] In particular, in the example illustrated, the internal part 19 of the head 7 comprises two first notches 22a formed circumferentially and each delimited by a respective first leading edge 23a and a respective second leading edge 23b opposite the respective first leading edge 23a (figures 7 and 8).

[0078] Each first leading edge 23a forms a first drive member configured to be urged and driven in rotation by the actuating tool 10 in a so-called clockwise direction, so as to screw the screw 4; while each second leading edge 23b forms a second drive member configured to be urged and driven in rotation by the actuating tool 10 in a so-called counterclockwise direction, so as to unscrew the screw 4 (see below).

[0079] In other words, each drive section 24 extends between a first leading edge 23a and a second leading edge 23b.

[0080] Figures 10 to 13 show the actuating tool 10 in more detail.

[0081] In the example illustrated, the gripping body 20 and the driving body 21 are separated by a guard-shaped wall 31.

[0082] The drive body 21 is provided with a mounting body 32 projecting from the gripping body 20, with the guard-shaped wall 31 being interposed between the mounting body 32 and the gripping body 20.

[0083] A first through hole 38 is provided radially in the mounting body 32.

[0084] The drive body 21 is further provided with a drive element 33, for example here in the form of a curved sheet metal, and configured to be mounted around the mounting body 32.

[0085] Second through holes 39 are provided in the drive element 33.

[0086] The drive element 33, in the form of a curved sheet, is split and provided at one end with several complementary drive members 35 in the form of an at least partially cylindrical blade, and with a spacing space 37, for example in the form of a window, between two successive complementary drive members 35.

[0087] Each complementary drive member 35 has a first complementary leading edge 41a, here configured to come into contact with a first leading edge 23a of the internal part 19 of the head 7 of the screw 4 to urge and drive the head 7 in rotation in the clockwise direction so as to screw the screw 4, and a second complementary leading edge 41b, here configured to come into contact with a second leading edge 23b of the internal part 19 of the head 7 of the screw 4 to urge and drive the head 7 in rotation in the counterclockwise direction so as to unscrew the screw 4.

[0088] The drive element 33 is configured to provide, between its complementary blade-shaped drive members 35, a receiving cavity 43.

[0089] The drive body 21 is also provided with a retaining ring 34, here cylindrical and configured to be mounted at least partially around the drive element 33.

[0090] Third through holes 40 are provided in the retaining ring 34.

[0091] The drive body 21 is also provided with an assembly member 36, for example here formed by a rivet.

[0092] The actuating tool 10 is configured such that the drive element 33 is mounted around the mounting body 32, with the second through holes 39 facing the first through hole 38 on either side of the mounting body 32, and the retaining ring 34 is partially mounted around the drive element 33, with the third through holes 40 facing the second through holes 39 and facing the first through holes 38 on either side of the mounting body 32; and with the assembly member 36 being mounted through the retaining ring 34, the drive element 33 and the mounting body 32, by the respective first, second and third through holes 38, 39 and 40, for their mechanical securing.

[0093] The actuating tool 10 is further configured so that the complementary members blade-shaped drive elements 35 of the drive element 33 extend projecting from the retaining ring 34, through an opening 42 of the latter.

[0094] Figures 14 to 18 show the mechanical securing of the first part 2 of the article 1 with its second part 3, thanks to the screw 4 which is driven in rotation by the actuating tool 10.

[0095] The first internal face 12 of the first part 2 is in contact with the second external face 15 of the second part 3, with the first orifice 5 which is opposite the tapped hole 16.

[0096] The screw 4 is arranged opposite the first part 2, with its distal end 30 on the side of the partially threaded body 8 which is opposite the first orifice 5.

[0097] The actuating tool 10 is engaged on the head 7 of the fixing screw 4, by means of its complementary drive members 35 which project from the retaining ring 34, leaving the gripping body 20 free of access.

[0098] In this configuration, the internal part 19 of the head 7 which is provided with drive members extending radially beyond the external part 18, is accessible to the actuating tool 10.

[0099] As can be seen in particular in Figures 15 and 16, the external part 18 of the head 7 of the screw 4 is received at least partially in the receiving cavity 43 formed between the complementary drive members 35 in the form of a blade and which project from the retaining ring 34.

[0100] The complementary blade-shaped drive members 35 are received in the first notches 22a formed in the internal part 19 of the head 7 of the fixing screw 4, between the drive sections 24.

[0101] In particular, each first complementary leading edge 41a of the complementary drive members 35 of the actuating tool 10 is opposite a respective first leading edge 23a of the internal part 19 of the head 7 of the screw 4 to urge and drive the head 7 in rotation in the clockwise direction so as to screw the screw 4.

[0102] Furthermore, in this same arrangement, each second complementary leading edge 41b of the complementary drive members 35 is opposite a respective second leading edge 23b of the internal part 19 of the head 7 of the screw 4 to urge and drive the head 7 in rotation in the counterclockwise direction so as to unscrew the screw 4.

[0103] In [Fig. 17], the screw 4 has been introduced through the first orifice 5 and its body 8 has been screwed into the tapped hole 16 thanks to the action of the actuating tool 10 on the head 7 of the screw 4.

[0104] The retaining ring 34 comes substantially against the first external face 11 of the first part 2 and the complementary drive members 35 are at least initially introduced into the radial clearance 28 formed in the first orifice 5 between the head 7 and the first part 2.

[0105] In [Fig. 18], the actuating tool 10 is removed and the first part 2 and the second part 3 are mechanically secured by means of the fixing screw 4, with the external part 18 of the head 7 of the screw 4 which comes flush with the first external surface 6 of this first part 2.

[0106] In this configuration, the drive members of the head 7 of the screw 4 are made invisible or almost invisible.

[0107] Only the external part 18 remains visible, which is devoid of an actuation imprint.

[0108] Figures 19 and 20 show an alternative embodiment of the fixing screw 4, in which the internal part 19 of the head 7 comprises notches which are distinguished from those described above and illustrated in particular in Figures 6 to 9.

[0109] In particular, the internal part 19 of the head 7 here comprises second notches 22b arranged circumferentially and each delimited by a third leading edge 50a, of the same type as the first leading edges described above, and by a curved receding edge 50b opposite the respective third leading edge 50a.

[0110] Each third leading edge 50a forms a first drive member configured to be urged and driven in rotation in the clockwise direction by the actuating tool 10, for example with a complementary drive member as described above, so as to screw the screw 4, and with the curved trailing edge 50b which prevents the drive in rotation in the counterclockwise direction of the head 7 by the actuating tool 10 and thus the unscrewing of the screw 4 and the mechanical unfastening of the first and second parts 2, 3 of the article 1.

[0111] Variants not illustrated are described below.

[0112] The screw head may have a single notch and a single drive section, with first and second leading edges as described above, or with a third leading edge and a trailing edge as described above.

[0113] The head of the screw may comprise more than two notches and therefore more than two driving sections, with a plurality of first and second leading edges as described above, or with a plurality of third leading edges and trailing edges as described above.

[0114] The drive sections may have leading edges with different shapes, and the actuating tool may also have complementary leading edges with different complementary shapes.

[0115] The actuating tool may comprise a drive element directly of material with the gripping body and / or with the mounting body.

[0116] More generally, the invention is not limited to the examples described and represented.
