The present invention relates to a snap button for garments/clothing, in particular for fastening and / or buttoning of clothing. More in detail, the present invention refers to a snap button, also known by the term automatic button for mechanically connecting two flaps, normally of a suit, for example a sports suit.
Therefore, the present invention finds advantageous use in the technical sector of the production and marketing of small parts, in particular metal, and of devices and accessories in the clothing sector, and more generally in the technical sector of the production and marketing of clothes, and clothing.
Many different types of buttons are known in the technical sector of reference, and in particular the snap buttons are known, also known in technical jargon as automatic buttons.
These snap buttons are devices capable of mechanically joining two free flaps of a suit, normally of sportswear, such as for example two front flaps of a jacket, for example of a gym suit.
The snap button of the known type comprises a female body, intended to be mechanically fixed to a first free edge of the aforementioned suit, and a male body, intended to be mechanically fixed to a second free edge of the dress, to be joined with the first flap for buttoning and closing said dress or garment.
More in detail, the male body of the known type snap button is configured to be mechanically coupled in a removable manner with the female body of the button itself, in order to mechanically connect the respective flaps of the garment to join them together. The female body defines a housing seat configured to receive a protruding element of the male body and lock the latter in a removable manner. For this purpose, the female body comprises an elastically yielding element that is movable during the insertion of the protruding element into the housing seat to assume a locking configuration, in which the elastically yielding element blocks the protruding element in the housing seat itself. Normally, the elastically yielding element of the female body of the snap button of the known type comprises an elastically yielding annular element, such as for example an elastic washer, i.e. a truncated annular element to allow its elastic expansion. In this way, the elastically yielding annular element is movable between a retracted configuration, in which it defines a first internal diameter, and an expanded configuration, in which it defines a second internal diameter in May of the first internal diameter.
Conveniently, the elastically yielding annular element is equipped with an internal diameter less than or equal to the overall dimensions of the protruding element of the male body, and configured to be intercepted by the latter during the insertion of the protruding element itself, to expand elastically the annular body, from the retracted configuration to the dilated configuration, to then return elastically to the retracted configuration when the protruding element is completely inserted in the housing seat. In this way, the retracted configuration coincides with the locking configuration when the protruding element of the male body is completely inserted inside the housing seat of the female body.
The elastically yielding annular element is arranged around an access mouth of the housing seat, held inside a special annular groove.
The annular groove located at the access mouth of the housing seat normally has larger internal dimensions than those of the elastically yielding element, in order to allow the latter to expand between the retracted configuration and the dilated configuration.
Female bodies for a snap button for clothing according to the preamble of claim 1 are described in documents
However, the snap button of the known type briefly described up to now has proved to be not free from drawbacks in practice.
The main drawback lies in the fact that the elastically yielding element housed in the annular groove defines a mechanical play with the internal walls of the latter. This mechanical play results in the fact that, with the snap button open, or with the flaps of the garment separated, the elastically yielding element hits the walls of the annular groove, generating an annoying rattle.
The jingle generated by the known type of snap button is unpleasant for the user and in fact makes this type of button unusable in fine clothing, relegating its usability to sportswear only, for which the tolerance to such noises is generally greater.
The object of the present invention is to propose a snap button for garments which allows to obviate, at least in part, the drawbacks of the aforementioned prior art.
A further purpose of the invention is to provide a snap button for clothing that is silent even when open, i.e. when the garment is held with the flaps separated from each other. A further purpose of the invention is to provide a snap button for clothing that is structurally completely reliable.
A further purpose of the invention is to provide a snap button for clothing that is functionally completely reliable.
A further purpose of the present invention is to provide a snap button for clothing which is simple and economical to make.
A further purpose of the present invention is to provide a snap button for clothing which is economically advantageous.
A further purpose of the present invention is to provide a snap button for garments which can be easily manufactured on an industrial level.
A further purpose of the invention is to provide a snap button for garments that can be colored and / or customized.
A further purpose of the invention is to provide a snap button for garments that is suitable for any type of garment.
A further purpose of the present invention is to provide a snap button for garments which is an alternative and / or an improvement with respect to traditional solutions. Another purpose of the present invention is to propose a snap button for garments which has an alternative and / or improved configuration, both in terms of construction and in terms of function, with respect to traditional solutions.
All these purposes, are achieved, according to the invention, with a female body for a snap button for garments according to claim 1.

Conveniently, the female body 2 of the button 1 is intended to be mechanically bonded to a first flap of a garment (not illustrated in the attached figures) and the male body 4 is designed to be mechanically bonded to a second flap of the garment to be mechanically connected to the first flap by means of the button 1 according to the invention.
For this purpose, the female body 2 comprises a side wall 14 which laterally delimits the housing seat 3 and is designed externally to be mechanically associated with the fabric of the aforementioned first flap of the garment.
The female body 2 comprises elastic retaining means 6 arranged in correspondence with said access mouth 20 of said female body 2, configured to detachably retain said protruding element 5 in said closed position and comprising at least one elastically yielding element 7 housed in a groove 8 formed in correspondence with said access mouth 20 and configured to intercept said protruding element 5 of said male body 4 in its movement between said closed position and said open position.
Conveniently, said female element 2 comprises at least one abutment wall 9 which delimits said groove 8 and abuts said elastically yielding element 7 to prevent the movements of said elastically yielding element along said direction of development X.
In this way, the elastically yielding element 7 of the elastic retaining means 6 normally remains in abutment against the abutment wall 9, preventing it from moving parallel to the direction of development X and obviating the risk that, striking against the internal walls of the groove 8 , you generate unwanted noises.
Therefore, the snap button according to the invention allows to prevent the movements parallel to the development direction X of the elastically yielding element 7 but allows its expanding movement inside the groove 8 to allow its movement from the retracted configuration to that expanded.
Advantageously, the groove 8 remains defined inside an annular shoulder 15 provided substantially at the first end 2'of the female body 2. Preferably, the annular shoulder 15 in which the annular groove 8 remains defined protrudes radially with respect to the direction of development. X with respect to the side wall 14 of the female body 2. Conveniently, the annular shoulder 15 develops radially starting from the side wall 14 with a support crown 16 intended to be placed against the fabric of the flap on which the female body 2 of the snap button 1 according to the invention will be applied. Advantageously, the elastically yielding element 7 is movable between a retracted configuration, in which it abuts against said abutment wall 9 of said groove 8, and an enlarged configuration, in which said elastically yielding element 7 is pushed into said groove 8 by said protruding element 5 of said male body 4 radially with respect to said development direction X.
More in detail, the elastically yielding element 7 has an annular shape, is housed inside the groove 8, and is preferably made of metal material. Conveniently, the elastically yielding element 7 is equipped with a separation section 17, designed to define a continuity separation section of the annular development of the elastically yielding element 7 itself.
This separation section 17 advantageously allows the widening of the elastically yielding element 7 in its movement between the retracted configuration and the enlarged configuration, inside the groove 8.
Advantageously, said protruding element 5 of said male body 4 extends between a first free end 5', equipped with a first transverse dimension, and a second end 5'. Conveniently, said protruding element 5 is equipped with at least a narrow section 18 interposed between said first end 5'and said second end 5' with a smaller transverse dimension compared to said first dimension.
Preferably, in accordance with the embodiment illustrated in the attached figures, the protruding body 5 has a substantially frusto-conical shape.
Advantageously, the male body 4 comprises a shoulder 21 protruding radially from the second end 5" of the protruding element 5. The shoulder 21 preferably has a substantially annular shape and is configured to abut against an upper wall 22 of the female body 2, in correspondence of the first end 2'of the latter, with the male body in its closed position. Advantageously, the elastically yielding element 7 internally defines a passage opening for said protruding element 5, in which said passage opening extends, with said elastically yielding element 7 in retracted configuration, less than or equal to said first bulk of said first free end 5'of said protruding element 5.
In this way, during the movement of the male body along the direction of development X to pass from the open to the closed position, the protruding element 5 passes through the access mouth 20 and intercepts an internal portion of the elastically yielding element 7, protruding from the groove 8, and forces the movement of the elastically yielding element 7 from its narrow configuration to the enlarged one.
Subsequently, continuing the movement of the male body 4 along the direction of development X, the protruding element 5 occupies the housing seat 3 and the elastically yielding element 7 of the elastic holding means 6 slides along the protruding element 5 until it reaches the narrow section 18 of the latter, elastically returning from the enlarged configuration to the narrow configuration, elastically locking the protruding element 5 inside the housing seat 3 and therefore mechanically connecting in a removable manner the male body and the female body of the button according to the invention. Conveniently, said elastically yielding element 7 is mechanically locked around said protruding element 5 in correspondence with said narrow section 18 with said male body 4 in the closed position.
Advantageously, said female body 2 comprises an annular bottom wall 10, which delimits said groove 8 and extends around the direction of development X.
Furthermore, the female body 2 is conveniently provided with an annular opening 11 opposite said annular bottom wall 10 crossed by said elastically yielding element 7 in a retracted configuration.
Preferably, said abutment wall 9 delimits said annular gap 11 with an annular edge thereof. Advantageously, as clearly visible in the attached figures, the abutment wall 9 is inclined and at least partially opposed to said bottom wall 10, delimiting said annular opening 11 with an annular edge thereof and receiving the abutment said elastically yielding element 7 in a retracted configuration.

Preferably, the abutment wall 9 is at least one folded edge of the shoulder 15 of the female body 2. In particular, the female body 2 is made in a single body, for example by punching, in metallic material, and the shoulder 15 is made by bending of a single circular side flap.
Advantageously, the annular opening 11 has an amplitude, parallel to the direction of development X, smaller than the size of the elastically yielding element 7, to block the latter in abutment against the abutment wall 9.
For this purpose, the diameter of the circle that remains defined internally in the annular gap 11 is preferably greater than the diameter that remains defined internally to the elastically yielding element 7 in its retracted configuration. In this way, the elastically yielding element 7 protrudes for at least a portion of it from the annular opening 11, configured to be intercepted by the protruding element 5 of the male body 4. Advantageously, said female body 2 comprises two abutment walls 9, provided with two corresponding annular edges which define each other said annular gap 11.
Preferably, the female body 2 comprises a first abutment wall 9 which substantially defines the access mouth 20 to the housing seat 3 and an abutment wall 9 internal to the housing seat 3 itself.

In this way, the groove 8 allows the resiliently compliant element to expand from retracted configuration to expanded configuration. Advantageously, the cross section of the elastically yielding element is to be understood as made along a plane of section passing through the direction of development X of the female body 2.
Conveniently, the cross section of the elastically yielding element 7 defines a restricted portion, which faces the abutment walls 9.
More in detail, the restricted portion of the cross section of the elastically yielding element 7 is equipped with at least one inclined wall and preferably two inclined walls.
More clearly, said cross section of said elastically yielding element 7 defines at least one inclined wall with respect to said transverse direction Y, configured to abut against said abutment wall 9 with said elastically yielding element 7 in retracted position.
In accordance with the preferred embodiment illustrated in the attached figures, the cross section of the elastically yielding element 7 is equipped with two distinct inclined walls, which develop at an angle with respect to the transverse axis Y approaching each other towards the direction of development X.
In other words, said cross section of said elastically yielding element 7 has a substantially drop shape, or has a substantially ogival shape, with a narrow portion facing the at least one abutment wall 9.
In accordance with a second embodiment of the present invention illustrated in the attached
In accordance with this second embodiment, the annular shoulder 15 which internally defines the groove 8 for the elastically yielding element 7 is made of two half-shells, in which the first half-shell 15'is preferably made in a single body with the side wall 14, in particular by bending, and the second half-shell is applied to the first half-shell and mechanically bonded to the latter by means of fixing, for example by welding or by interlocking. In this way, the second half-shell can be made in any desired shape, not being subject to the limitation of forming by bending. For example, the second half-shell can be made of a different material than the first half-shell and / or have a different and / or more expensive color than that of the first half-shell.
