Definitions

  • the present invention relates to an automatic press-­button of a perfected type.
  • press-­button is meant a two-component cluster, specifically male and female, respectively endowed with a protrusion and with a cavity or opening, in which the protrusion engages and disengages with respect to said cavity by exerting a pressure or a traction on the component bearing the protrusion.
  • the two components are normally in metal and are individually fixed by sewing or riveting to cloth edges which are to be mutually buttoned.
  • a first problem related to such automatic press-­buttons, and which intervenes especially in case of fixing by sewing, is that said sewing operation entails greater time and labour expense in the industrial production of clothing.
  • a further disadvantage which automatic press-buttons of the known type may present derives from the fact that they are endowed on the outside with a surface which is smooth and suitable for receiving drawings, inscriptions, signs and the like, so that in this case the problem is posed of aligning appropriately the heads relative to a common direction, especially relative to the employment in an automatic machine for the assembly of the male and female components and for their fixing to the cloth.
  • the main object of this invention is to eliminate such problems and inconveniences, while keeping the functionality of the automatic press-button unchanged.
  • an important object of the invention is to produce an automatic press-button the head of which may be aligned according to a direction shared with the other buttons even by means of modern automatic fitting machines.
  • an automatic press-button of the kind which comprises a male component endowed with a protrusion an a female component endowed with a receptacle in which said protrusion penetrates in an extractible manner, the latter being elastically compressible transversely or radially, characterized in that said male and female components are formed of disk-like elements, each provided with said protrusion and said cavity or opening, each disk-like element being provided with a plurality of through holes or openings, each of said disk-like elements being coupled to a head or closing element, from which a plurality of pointed stems protrudes, which stems are suitable for being introduced in said through holes of said disk-­like elements, said pointed stems having such a length as to protrude of a preset amount from the opposite surface of said disk-like elements so as to be able to be cold-headed, locking together the disk-like element and the head with interposed an edge of cloth or of any other material to be buttoned, each element
  • said receptacle is an opening, surrounded towards the proximate head by a frame protruding towards the head itself, said receptacle being endowed with retention means, such as notches and the like, in order to prevent the respective rotation of the male and of the female component.
  • Figs. 1 and 4 illustrate two heads which are respectively identical with the exception of the fact that one of them is endowed with a central opening.
  • Said head which is indicated with reference 10, is composed of a disk 11, provided, if required, with a central opening 12. From the lower surface of the disk 11 four pointed stems 13 protrude, with the subsequently described purpose, which are angularly equidistant.
  • the female component of the button which is formed by the subsequently described coupling of the elements illustrated in figs. 1 and 2, furthermore comprises the disk-like element 14, provided with a central opening 15 and with four through holes 16, said through holes having such a diameter as to receive the pointed stems 13 of the bottom 10.
  • the through holes produced in the disk-like element are provided with an increase in diameter towards the base 17 of the disk-like element, that is to say, towards the surface which is not oriented towards the head 10.
  • the excess plastic material finds a location in the section having an enlarged diameter, and contributes to the safe securing of the head 10 to the disk-like element 14.
  • the disk-­like element is tapered towards the outer edge, thus making easier the opening operation of the automatic press-button.
  • the opening 15 is surrounded by a frame 18, which has the function of guiding and orientating the button in the coupling and cloth-fixing machine and of aiding in the securing of the female component to the cloth 19 (as illustrated in Fig. 5), which is deflected towards the interior of the remaining cavity, after the coupling and the securing to the cloth, between the head 10 and the disk-like element 14.
  • the opening 15 made in the disk-like element 14 is provided with an internal ridge 20, which represents the actual press-buttoning neck with the subsequently described male component.
  • a plurality of notches 21 is provided, radially protruding from the internal surface of the opening itself and angularly equidistant.
  • Said notches are, as an example, in number of six and 60 degrees apart.
  • the male component again comprises a head 10, this time illustrated with the external part devoid of a central opening, and a disk-­like element 22, which is endowed with a notching similar to that of the disk-like element 14 and provided for the same purpose.
  • the through holes 23 are provided, suitable for receiving the pointed stems 13, in the same manner as already described for the other disk-like element 14 and with the same widening of the through holes 16.
  • the protrusion 25 protrudes, which is axially divided by a cut 26 into two halves, so as to allow for the elastic compression in the radial direction when said protrusion is to pass through opening 15 and in particular through the diameter of the ridge 20 during the buttoning and unbuttoning phase of the button.
  • a frame 28 protrudes, having the same function as the protruding frame 18 of the disk-like element 14.
  • the two halves 29 and 30 in which the protrusion 25 is divided by cut 26 compose sectors of a circle with non-­coinciding centres, and become part of the same circle only during a radial compression phase.
  • the outer surface 35 of the heads 10 is easily suitable for receiving a figure or an inscription, so that there is the requirement of a common reference point or orientation element, so that in an automatic machine for the fixing of the buttons, said buttons are orientated and then fixed to the edges of the cloth with an appropriate orientation.
  • a shaped element 32 protrudes, which can be engaged by a mechanical positioning finger, suitable for rotating the head 10 around its axis so as to always bring it to a preset position of the shaped element 32, and therefore with a preset orientation of the drawing or inscription with which the surface 35 of said head is endowed.
  • a shaped hollow 33 can be provided, having the same function.
  • a shallow part 34 can be formed.
