Description

Title of the invention: CONFIGURED FIXING SYSTEM FOR EQUIPING AN ARTICLE AND ASSOCIATED ASSEMBLY AND DISASSEMBLY METHOD TECHNICAL FIELD OF THE INVENTION

[0001] The present invention relates to a fastening system configured to equip an article, in particular leather goods, or textiles, cosmetics or furniture.

[0002] The invention also relates to such an article, in particular leather goods, or textiles, cosmetics or furniture, provided with such a fastening system and at least a first part configured to be mechanically attached to any support using the fastening system.

[0003] The invention also relates to a method of attaching and / or unattaching such an article using such a fastening system. STATE OF THE ART

[0004] We know of articles for example of leather goods, each comprising a first part and a second part mechanically attached to the first part by means of so-called snap buttons, or snap buttons, each provided with a male part attached to the first part and a female part attached to the second part of the article and configured to cooperate with the male part.

[0005] The male part may include a base from which protrudes a pin having an enlarged end portion, while the female part may include a body in which is provided an internal cavity in which protrude spring blades.

[0006] The internal cavity of the body of the female part defines an inlet opening for the enlarged end portion of the pin of the male part and the spring blades are configured so as to admit a stable configuration deployed in the internal cavity and a retracted configuration.

[0007] In particular, when the enlarged end portion of the male part's pin is introduced through the introduction opening into the internal cavity of the female part's body, by the effect of a pressure or push force exerted by a user, the enlarged end portion spreads the leaf springs apart, which move from their deployed configuration to their retracted configuration in which the enlarged end portion can be inserted into the internal cavity.

[0008] Once the enlarged end portion is sufficiently inserted into the internal cavity, the spring blades return to their stable deployed configuration, thus locking the enlarged end portion in the internal cavity and incidentally securing the part male and female part, and therefore the first and second parts of the article.

[0009] The disengagement of the first and second parts of the article is done by reverse movement, by separating the male and female parts. Description of the invention

[0010] The present invention aims to provide a fastening system configured to mechanically attach at least a first part of an article to any support, of a similar kind, and which is particularly simple and convenient both to manufacture and to use.

[0011] The invention thus relates, according to a first aspect, to a fastening system configured to mechanically attach at least a first part of an article, in particular of leather goods, or of textiles, cosmetics or furniture, to any support, the fastening system comprising a male element configured to be attached to one of the first part and the support, and a female element configured to be attached to the other of the support and the first part and to cooperate, by elastic deformation, with the male element when the first part is mechanically attached to the support;the fastening system being characterized in that the female element is formed by a generally flat and elastically deformable pad, which pad is provided with a through orifice defining an entry opening for the male element, and in that the fastening system is configured so that the entry opening is variable, between a minimum value when the pad is not stressed and a maximum value when the pad is stressed by the male element for the purpose of mechanically fastening or unfastening the first part and the support. ;

[0012] In the fastening system according to the invention, the inlet opening for the male part, which is defined by the through orifice of the pellet, is variable by the elastic deformation of the pellet alone.

[0013] In other words, such a fastening system does not require additional deformable parts, such as leaf springs, which are typically required for the female element of a snap fastener.

[0014] Thus, such a fastening system allows the mechanical fastening or unfastening of the first part of the article and the support by a variation of the introduction opening, defined by the through orifice of the pellet, when the pellet is stressed by the male element.

[0015] Preferred, simple, convenient and economical features of the fastening system according to the invention are presented below.

[0016] The through orifice provided in the pellet can be delimited by an internal contour forming a hook edge for the male element.

[0017] The internal contour of the through orifice can be generally circular, oblong or rectangular and the male element can have a head of substantially complementary shape.

[0018] The pellet may be provided with deformation zones around the through orifice.

[0019] The deformation zones can be formed of notches and / or slots extending radially from the through orifice.

[0020] The pellet may have an overall circular outer contour.

[0021] The pellet can come from material with a reinforcing piece of the first part of the article or of the support.

[0022] The female element may comprise several generally flat and elastically deformable pellets arranged adjacently in the first part or in the support, and with their respective through orifices opposite each other.

[0023] The pellets can be separated by a first element of material from the first part or support.

[0024] The male element can be formed by a pin having a head extending outward from the first part or support and configured to be inserted at least partially through the through-hole of the pellet.

[0025] The through orifice provided in the pellet can be delimited by an internal contour forming a gripping edge, and the head of the pin can be provided with a protuberance configured to exert pressure on the pellet around its through orifice to vary the introduction opening and a recess against which the gripping edge rests when the first part is mechanically secured with the support.

[0026] The pawl may be provided with a base on which the head is mechanically secured, with a second element of material from the first part or support which is sandwiched between the head and the base.

[0027] The invention also relates, according to a second aspect, to an article, in particular of leather goods, or of textiles, cosmetics or furniture, comprising a fastening system presented above and at least a first part configured to be attached to any support using the fastening system.

[0028] The invention also relates, according to a third aspect, to a method of attaching a first part of an article, in particular leather goods, or textiles, cosmetics or furniture, to any support, using a fastening system presented above, comprising the step of introducing the male element into the disc through the introduction opening, by stressing the disc by elastic deformation so as to temporarily enlarge its through orifice.

[0029] The invention also relates, according to a fourth aspect, to a method of disabling subjecting a first part of an article, in particular leather goods, or textiles, cosmetics or furniture, to any support, using a fixing system presented above, comprising the step of extracting the male element of the disc through the introduction opening, by elastically deforming the disc so as to temporarily enlarge its through orifice.

[0041] Figures 1 and 2 partially illustrate an article 1, here of leather goods, provided with a first part 2 and a second part 3 forming a support.

[0042] In [Fig.1], the first part 2 and the second part 3 are mechanically fastened together using a fastening system 10, while in [Fig.2], the first part 1 and the second part 2 are at a distance from each other.

[0043] The first part 2 of article 1 is here formed of a first element of material 23 and a second element of material 24 adjacent to and subject to the first element of Material 23.

[0044] The first part 2 has a first external face 21 formed on the first material element 23 and a second external face 22, which is opposite to the first external face 21, and which is formed on the second material element 24.

[0045] The first part 2 further has a first orifice 20 passing through the first material element 23 and the second material element 24 and opening on either side of the first external face 21 and the second external face 22.

[0046] The second part 3 of article 1 is formed here of a single element of material, also called third element of material, and has a third internal face 31 and a third external face 32 opposite to the third internal face 31.

[0047] For the assembly of the first part 2 of article 1 with the second part 3 of article 1, the second external face 22 of the first part 2 is arranged opposite the third internal face 31 of the second part 3, as seen in [Fig.2].

[0048]

[0049] In the illustrated example, the second part 3 is provided here with a second orifice 30, arranged so as to pass through the second part 3 on either side of its third external face 31 and fourth external face 32.

[0050] The fastening system 10 comprises a male element 5 subjected to the second part 3 of article 1, and a female element 4 which is subjected to the first part 2 of article 1 and which is configured to cooperate, by elastic deformation, with the male element 5 when the first part 2 is mechanically subjected to the second part 3 (see below).

[0051] With reference to [Fig.3] to 6, the female element of the fastening system 10 is formed by a generally flat and elastically deformable pellet 4, while the male element of the fastening system 10 is formed by a pin 5.

[0052] In particular, the pellet 4 is provided with a through orifice 40 defining an introduction opening 42 for the pin 5.

[0053] The pellet 4 can be made of metal or of plastic or composite material.

[0054] The fastening system 10 is configured so that the insertion opening 42 is variable, between a minimum value when the pad 4 is not stressed and a maximum value when the pad 4 is stressed by the pin 5 for the purpose of mechanically securing or unsecuring the first part 2 and the second part 3.

[0055] The pellet 4 has an internal contour 41 delimiting the through orifice 40, and an external contour 45 which is here generally circular.

[0056] The internal contour 41 forms a hook edge for the pin 5.

[0057] The internal contour 41 of the through orifice 40 is here globally circular.

[0058] In the illustrated example, the disc 4 is provided with a plurality of de- formation 43 arranged around the orifice passing through 40.

[0059] The deformation zones 43 have slots 44 extending radially from the through orifice 40.

[0060] In other words, the slots 44 extend from the inner contour 41 to the outer contour 45 of the pellet 4.

[0061] In the illustrated example, the pellet 4 has ten slots 44 which are globally and regularly distributed around the through orifice 40.

[0062] These slots 44 allow the deformation of the pellet 4 at the level of its internal contour 41 and thus the variability of the introduction opening 42.

[0063] The pellet 4 is here configured to be sandwiched between the first material element 23 and the second material element 24 of the first part 2 of article 1.

[0064] In particular, the pellet 4 is interposed between a first internal face 25 of the first material element 23 which is opposite its first external face 21, and a second internal face 26 of the second material element 24 which is opposite its second external face 22.

[0065] In other words, the first material element 23 is secured by its first inner face 25 to the second inner face 26 of the second material element 24, with the pellet 4 sandwiched and immobilized in position, with the through orifice 40 of the pellet 4 which is globally arranged opposite the first orifice 20 of the first part 2, or even centered with the first orifice 20.

[0066] It will be noted that the orifice through 40 of the pellet 4 has an internal diameter which is substantially equal to or slightly less than the diameter of the first orifice 20 provided in the first part 2 of article 1.

[0067] In other words, the inner contour 41 of the pellet 4 comes substantially flush or protrudes slightly into the first orifice 20, in particular when the inlet opening 42 is at its minimum value.

[0068] The pellet 4 is thus inserted between the first material element 23 and the second material element 24, without damaging the first material element 23 and / or the second material element 24, and being invisible or almost invisible from outside article 1.

[0069] In addition, the pin 5 here has a base 51 and a head 50 projecting from the base 51.

[0070] The base 51 of the pin 5 has a base 57 and a threaded rod 58 projecting from the base 57.

[0071] The base 57 is configured to be positioned against the third external face 32 of the second part 3 of article 1, with the threaded rod 58 which passes through a second orifice 30 made in the second part 3 and opening on either side of its third external face 32 and third internal face 31.

[0072] The head 50 is configured to be screwed onto the base 51.

[0073] In particular, the head 50 here has a threaded internal cavity 56 opening at a proximal end 49 of the head 50.

[0074] The head 50 is configured to bear, by means of a shoulder 48 provided on the side of its proximal end 49, on the third internal face 31 of the second part 3, with the proximal end 49 which is introduced into the second orifice 30.

[0075] The internally tapped cavity 56 of the head 50 is configured to receive the threaded rod 58 of the base 51 for their mechanical fastening.

[0076] Thus, the pin 5 has its head 50 which extends in projection from the third internal face 31 of the second part 3 of article 1, with the second part 3 of article 1 which is partially sandwiched between the head 50 and the base 51 of the pin 5.

[0077] The head 50 here has a shape substantially complementary to the internal contour 41 of the orifice passing through 40 of the pellet 4, in particular globally circular.

[0078] In the illustrated example, the head 50 has an external contour 54 extending between the proximal end 49 and a distal end 55 opposite the proximal end 49, as well as a recess 53 circumferentially formed on the external contour 54, on the side of the distal end 55.

[0079] The external contour 54 of the head 50 located between the recess 53 and the distal end 55 forms a protuberance of the head 50.

[0080] It will be noted that the protuberance of the head 50 may have a beveled portion in the direction of the distal end 55.

[0081] It will also be noted that the head 50 has an external diameter substantially equal to or less than the first orifice 20 of the first part 2 of article 1 and greater than the internal diameter of the pellet 4, when the introduction opening 42 has its minimum value.

[0082] We will now describe, with reference in particular to figures 5 and 6, the cooperation of the pawl 5 with the pellet 4 and therefore the assembly of the second article 3 with the first article 2.

[0083] The head 50 of the pin 5 is introduced at least partially into the first orifice 20 of the first part 2 and through the introduction opening 42 delimited by the internal contour 41 of the pellet 4, that is to say into the through orifice 40 of this pellet 4.

[0084] In particular, the protuberance defined by the portion of the external contour 54 of the head 50 located between the recess 53 and the distal end 55 exerts stress on the internal contour 41 of the pellet 4 and enlarges the introduction opening 42 by deformation of the pellet 4 at the level of the deformation zones 43.

[0085] In other words, the slots 44 move apart to widen the inlet opening 42 from its minimum value to a value closer to its maximum value, in depending on the diameter of the head 50 and thus allow the distal end 55 of the head 50 to pass through to the recess 53.

[0086] At the level of the recess 53, the internal contour 41 of the pellet 4 is no longer or is less stressed so that the introduction opening 42 narrows until the hook edge of the pellet 4 comes into the recess 53 of the head 50.

[0087] In this configuration, the head 50 of the pin 5 is assembled with the pad 4 and the second article 3 is mechanically secured with the first article 2.

[0088] The mechanical disengagement of the first part 2 with the second part 3 of article 1 is carried out in a reverse movement to that described above, but with a similar effect on the introduction opening 42 of the pellet 4.

[0089] The extraction of the pin 5 through the introduction opening 42 is done by elastically deforming the deformation zones 43 of the pellet 4, with the slots 44 spreading apart to widen the introduction opening 42 from the value corresponding to the diameter of the recess 53 of the head 50 to a value closer to its maximum value, and thus allow the head 50 to emerge from the through orifice 40 and the first orifice 20.

[0090] In the description of the pellet 4, with reference in particular to Figures 3 to 6, the latter has an external contour 45 of a determined external diameter and thickness. The deformation zones 43, and therefore the slots 44 formed in this pellet 4, have dimensions that depend on this determined external diameter and thickness, as well as on the desired minimum and maximum values ​​of the inlet opening 42.

[0091] Fig. 7 shows a pellet 4 which differs from the pellet described above only in that it has an external contour of greater external diameter and also a greater thickness, so that the deformation zones 43 and the slots 44 formed in this pellet 4 can for example be larger.

[0092] Fig. 8 shows a pellet 4 which differs from the pellet described with reference to Figures 3 to 6 only in that it has a larger number of slots 44, in particular sixteen, forming the deformation zones 43.

[0093] Figure 9 illustrates a pellet 46 which differs from the pellet 4 described with reference to Figures 3 to 6 in that the through orifice 40 has an internal contour 41 that is generally rectangular rather than circular. The same is true of the insertion opening, and therefore the head of the pin must also be similar.

[0094] In the pellet 46, the deformation zones 43 have slots 44 which extend from the inner contour 41 to an outer contour, substantially parallel to each other from a respective side of the rectangle formed by the inner contour.

[0095] Figure 10 illustrates a pellet 47 which differs from the pellet 4 described with reference to Figures 3 to 6 in that the deformation zones 43 have, in addition to the slots 44 which extend from the internal contour 41 of the orifice through 40, notches 39 made regularly along the internal contour 41.

[0096] Fig. 11 is a view similar to that of Fig. 2, showing an article 1 with its first part 2 at a distance from its second part 3 and the associated fastening system 10.

[0097] The fastening system 10 differs from that already described with reference to the previous figures, in that it is provided with two pads 4 and two recesses 53 made on the external contour 54 of the head 50 of the pin 50.

[0098] The first part 2 of article 1 comprises an intermediate material element 27 interposed between the first material element 23 and the second material element 24, with one of the pellets 4 which is sandwiched between the first material element 23 and the intermediate material element 27 and the other of the pellets 4 which is sandwiched between the second material element 24 and the intermediate material element 27.

[0099] The two pellets 4 can be identical or different.

[0100] For example, they may have different thicknesses and thus generate two stress forces for the assembly of the first part with the second part, and / or two assembly positions.

[0101] Indeed, the recess 53 closest to the distal end 55 can cooperate with the pad 4 sandwiched between the second material element 24 and the intermediate material element 27, so that the first part 2 and the second part 3 are secured according to a first assembly position.

[0102] In addition, the recess 53 closest to the distal end 55 can cooperate with the pad 4 sandwiched between the first material element 23 and the intermediate material element 27 and the other recess 53, further from the distal end 55, can cooperate with the pad 4 sandwiched between the second material element 24 and the intermediate material element 27, so that the first part 2 and the second part 3 are secured according to a second assembly position, where the head 50 is pushed deeper into the first orifice 20 of the first part 2 of article 1.

[0103] In the fastening system 10 described above, the introduction opening 42, which is defined by the through orifice 40 of the pellet 4, is variable by the elastic deformation of the pellet 4 alone.

[0104] In other words, such a fastening system 10 does not require additional deformable parts, such as leaf springs, which are typically required for the female element of a snap fastener.

[0105] Thus, such a fastening system 10 allows for the mechanical attachment or detachment of the first part 2 of article 1 and of the second part 3 of Article 1 by a variation of the introduction opening 42, defined by the through orifice 40 of the pad 4, when the pad 4 is stressed by the pin 5.

[0106] Variants not illustrated are described below.

[0107] The article may be a jewelry item, or a textile, cosmetics or even furniture rather than a leather goods item.

[0108] The first part of the article may be formed from a single element of material.

[0109] The second part of the article can be formed by several material elements.

[0110] The support may not be formed by a second part of the article, but rather to be distinct from this article.

[0111] The pellet can be made of an elastically deformable material and not have any notch and / or slot, the opening for insertion of the pellet then being variable by the only elastic deformation of its through orifice.

[0112] The pellet can come from material with a reinforcing piece of the first part of the article or of the support.

[0113] The internal contour of the through orifice of the pellet may be oblong or rectangular, or of any other shape.

[0114] The pellet may be provided with a single deformation zone around the through orifice.

[0115] The deformation zones can be formed of notches or a mixture of slots and notches.

[0116] The outer contour of the pellet may be oblong or rectangular, or of any other shape.

[0117] The pad can be configured to be subjected to the second part of the supporting article, rather than the first part, and the pawl is then subjected to the first part rather than the second part of the article.

[0118] The pawn may have an oblong or rectangular head, or any other complementary shape rather than circular.

[0119] The protuberance formed on the head of the pin may have a diameter greater than that of the head of the pin.

[0120] The head and base of the pin can be secured by clipping, crimping, welding or any other suitable assembly rather than by screwing.

[0121] The pawl can be made in one piece and attached to the first or second part of the article by gluing, sewing or any other suitable method of attachment.

[0122] In the illustrated examples, the first orifice 20 is through, but it could be blind, in particular with an additional material element disposed on the first external face and covering the first orifice.

[0123] More generally, the invention is not limited to the examples described and represented.
