The present invention relates to an active male element for an improved pression button.
The invention also relates to a pression button including the inventive active male element.
The field of the invention is that of the pression buttons conventionally used for mutually attaching two flaps, for example of a garments or other article in general, said garment or article being made of a fabric, paper, plastic material, preferably in a sheet form.
The above pression buttons usually comprise a male portion to be attached to a first flap to be coupled, and a female portion, rigid or integral with the other flap.
Each button portion is in turn constituted by an active element, forming the male/female component of the button, and by a clamping element for clamping the active element on the fabric, paper or the like flap.
In particular, the pression button male component active element comprises a contoured or shaped body, made by plastically deforming a sheet element, and including a peripheral annular groove, designed for clamping therein an elastic element of the button female portion.
The above prior pression buttons have the drawback that their annular groove is undesirably deformed under load, as the pression button male portion is applied to the fabric flat.
Thus, the pression button coupling and releasing force undesirably changes, thereby in turn preventing a proper operation of the pression button.
To the above drawbacks, the disadvantage is further added that, because of its comparatively large size, the male portion constitutes an anti-aesthetic component of the fabric the pression button is applied to.
The document
Thus, the main object of the present invention is to provide such a pression button active male element overcoming the above drawbacks occurring as the active male element is applied to its supporting fabric flap.
Within the scope of the above mentioned aim, a main object of the invention is to provide such an active male element and related pression button which do not have the antiaesthetic effects affecting like prior art pression buttons.
According to one aspect of the present invention, the above aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by the active male element and pression button as claimed in the accompanying claims.
Preferred embodiments of the invention are disclosed in the dependent claims.
With respect to prior pression buttons, the inventive button has the advantage that its active male portion preserves its designed dimensions, and is not negatively affected by the operating effort exerted for applying the active male portion on the fabric flap.
Moreover, the inventive pression button has the advantage of a pleasant aesthetic aspect, owing to its small size and the very simple and essential pattern of the exposed to the view pression button active male portion section.
The above mentioned and further objects, advantages and features of the invention will become more apparent hereinafter from the following detailed disclosure of a preferred embodiment of the active male element and pression button according to the present invention as shown, by way of a non limitative but indicative example, in the accompanying drawings, where:
A prior art pression button, generally indicated by 1 in
In turn, the female portion 2 comprises a clamping element 6 and an active female element 7, whereas the male portion 3 comprises a clamping element 8 and an active male element 9.
In operation, a projection 10 of the active male element 9 will be fitted in a seat 11 of the active female element 7.
In clamping the male element 3 to the fabric flap 5, the connection of the male clamping element 8 made in the active male element 9, may deform an annular or ring groove 12 formed outside of said projection 10.
Thus, the clamping of said projection 10 in said seat 11 is changed, with a consequent variation of the pression button 1 releasing load.
In order to overcome the above drawback, the pression button 13 according to the present invention, shown in
More specifically, said active male element 14 comprises an active male element head 15 and an active male element stem 16, said head 15 comprising a peripheral annular groove 17 for engagement in said active female element 7 seat 11.
Moreover, in the under-head portion of the element 4, a second groove 18, for engaging therein the corresponding fabric flap 5, by pressing on the male clamping element 19, is provided.
According to the present invention, said clamping male element 19 comprises moreover a contoured or shaped annular body 20 including an outward turned portion 21 for engaging in said groove 18 of the active male element 14.
Said male clamping element 19, in turn, further comprises a cap element 22 assembled on the head 23 of the contoured annular body 20.
As is clearly shown by the detail of
In particular, owing to a comparatively large extension of this portion 24, due to the arch contour of the outward turned part 21-groove 18 connection, a very efficient anchoring of the button 13 male portion 3 to the fabric flap 5, even if an active male element 14 including a small size head 15 is used is achieved.
