Definitions

  • the present invention relates to a swivel tack button, particularly for items of clothing such as jeans or the like, with very simple assembly and application.
  • So-called swivel tack buttons for items of clothing such as jeans or the like are known.
  • the part to be coupled to the buttonhole of the item of clothing is movably associated with the remaining part of the button, which is rigidly fixed to the item of clothing.
  • buttons are generally made of metal and comprise a cup-shaped cap holder, usually termed “shank”, which is provided with a hole at its bottom and is closed in an upward region by the cap, which can be closed completely or be crossed centrally by a hole.
  • the cap holder is associated with a supporting element, usually termed “foot”, which is generally provided with a head that has a circular plan shape and with a stem that is usually cylindrical, protrudes from the head and enters with play the hole formed in the bottom of the cap holder.
  • the button is completed by a fixing element, which is usually shaped like a tack and pierces, by means of its stem, the fabric of the item of clothing and fixes itself in a seat provided for this purpose in the supporting element so as to clamp the fabric between the head of the fixing element and the head of the supporting element in order to rigidly couple the button to the item of clothing.
  • the play between the hole of the cap holder and the stem of the supporting element allows the assembly constituted by the cap holder and by the cap a certain mobility, which facilitates insertion and removal from the buttonhole.
  • Buttons of this kind are generally provided with the supporting element, the cap holder and the cap in a preassembled condition.
  • the stem of the supporting element is generally hollow and open at its ends, and, during the first step of the assembly, which is performed with a machine having dual feeds, one for the supporting elements and one for the cap holders, the end of the stem of the supporting element inserted in the cap holder is inserted and riveted by means of a punch.
  • buttons provided with a closed cap For buttons provided with a closed cap, during the second step of assembly, a riveting element is inserted in the cap holder and such second step of assembly is performed with a machine having three feeds: one for the assemblies constituted by the supporting element and the cap holder, one for the riveting elements, and one for the caps.
  • the riveting element is not present.
  • the stem of the tack that constitutes the fixing element is hollow and is open at one, or sometimes both, of its ends in a manner similar to the supporting element, while in other kinds of button said stem is solid.
  • the connection between the fixing element and the supporting element is generally provided by riveting the end of the tack that passes through the fabric and enters the supporting element.
  • buttons provided with a closed cap The operation of riveting the end of the tack that constitutes the fixing element, in buttons provided with a closed cap, is achieved by adequately forceful pressing of the tack against the riveting element inserted beforehand in the cap holder, whereas in buttons provided with an open cap it is achieved by means of a punch that is inserted through the central opening of the cap and interferes with the end of the tack.
  • buttons provided with a closed cap the presence of the riveting element is often unwanted, since it can damage the cap during tack riveting, i.e., during application of the button to the item of clothing. This damage constitutes a problem, since it alters the manufacturer's mark, which is usually stamped into the cap.
  • buttons of this kind both with a closed cap and with an open cap, have the problem that they produce noise during use of the item of clothing because of the movement of the cap holder with respect to the supporting element.
  • an object of the invention is to provide a swivel tack button that does not require riveting of the fixing element in order to be assembled and associated with the item of clothing.
  • Another object of the invention is to provide a swivel tack button which, if provided with a closed cap, can have a smaller number of components than those required by conventional kinds of swivel tack buttons with closed cap, thus reducing production costs and simplifying the machine for performing the second step of button assembly.
  • Another object of the invention is to provide a swivel tack button which, if provided with an open cap, does not require operations for riveting the fixing element during its application to the item of clothing, thus simplifying the apparatus used for this operation.
  • Another object of the invention is to provide a button that fully meets the aesthetic requirements in the particular field in which it is used.
  • Another object of the invention is to provide a swivel tack button that is not noisy during use. This aim and these and other objects that will become better apparent hereinafter are achieved by a swivel tack button, particularly for items of clothing such as jeans or the like, according to claim 1.
  • Figure 1 is an exploded perspective view of the button according to a first embodiment of the invention
  • Figure 2 is a partially sectional exploded view, taken along an axial plane, of the button according to the invention
  • Figure 3 is an axial sectional view of the button according to the invention in an intermediate assembly condition
  • Figures 4 to 6 illustrate the mobility of the button according to the invention, shown in an axial sectional view and applied to an item of clothing
  • Figure 7 is an axial sectional view of a second embodiment of the button according to the invention.
  • the button according to the invention comprises a cap holder 3 or shank, a supporting element 4 or foot, and a fixing element 5.
  • the cap holder 3 is preferably made of metallic material, for example steel, and has a through hole 6 on its bottom.
  • the top of the cap holder 3 is provided with a rim 7 that is folded outwardly.
  • the supporting element 4 has a head 8 and a stem 9 that is preferably cylindrical and protrudes from one face of the head 8.
  • the head 8 of the supporting element 4 has a circular plan shape and the stem 9 protrudes coaxially with respect to the head 8.
  • the stem 9 can be inserted through the hole 6 of the cap holder 3 and has, along at least one portion of its axial extension, a smaller diameter than the hole 6, so that coupling between the cap holder 3 and the supporting element 4 is a slack coupling that allows the intended mobility of the cap holder 3 with respect to the supporting element 4, shown in Figures 4 to 6 and described in greater detail hereinafter.
  • the button according to the invention can be provided with a closed cap 2, as shown, or with an open cap, depending on the requirements.
  • the cap 2 can be made of metallic material, for example steel, and seamed onto the rim 7 of the cap holder 3, or can be made of synthetic material and be connected in another manner to the cap holder 3.
  • the cap 2 may also be omitted.
  • the cap holder 3 may optionally be made of molded synthetic material.
  • the cap holder 3 can be formed monolithically with the cap 2 or can be connected to a closed or open cap 2 provided separately from the cap holder 3.
  • the supporting element 4 is made of synthetic material, preferably nylonTM, and the stem 9 of the supporting element 4 has, at its opposite end with respect to the head 8, an expansion 10 that has a larger diameter than the hole 6 formed in the bottom of the cap holder 3 in order to achieve retention of the cap holder 3 by the supporting element 4.
  • the fixing element 5 comprises a tack, which can be inserted with interference in a seat 11 provided in the supporting element 4 starting from the head 8 in order to clamp the fabric 12 of the item of clothing, to which the button 1 is to be applied, between the head 13 of the fixing element 5 and the head 8 of the supporting element 4, as shown in Figures 4 to 6.
  • the fixing element 5 can be made of metallic material, for example aluminum or copper alloy, and the end of the stem 14 of the fixing element 5 is preferably pointed so as to facilitate piercing of the fabric 12 by the fixing element 5.
  • the fixing element 5 can also be made of molded synthetic material of suitable strength.
  • the stem 14 of the tack which constitutes the fixing element 5, at least on its portion that can be inserted in the receptacle 11, can be provided with circumferential crests in order to increase cohesion by friction between the tack that constitutes the fixing element 5 and the supporting element 4.
  • the stem 14 of the tack ends with a conical tip 14a, in which the base is directed toward the head 13 and the diameter is slightly larger than the diameter of the remaining part of the stem 14 and the diameter of the receptacle 11 of the supporting element 4 in which the stem
  • the expansion 10 of the supporting element 4 is reinforced and/or increased by means of the engagement of the locking element 5 with the supporting element 4.
  • the expansion 10 of the stem 9 of the supporting element 4 which lies opposite with respect to the head 8, is preferably constituted by an expansion 15, which is provided during the molding of the supporting element 4 and has a larger diameter than the remaining part of the stem 9.
  • the expansion 15 is preferably shaped like a truncated cone, in which the larger flat face is directed toward the head 8.
  • Such larger flat face of the expansion 15 has a larger diameter than the hole 6, so as to define a shoulder that effectively contrasts extraction of the stem 9 from the hole 6 once the stem 9 has been inserted in the cap holder 3.
  • the smaller flat face of the expansion 15 preferably has a diameter that is substantially equal to the diameter of the cylindrical part of the stem 9, i.e., a diameter that is smaller than the diameter of the hole 6, so as to facilitate insertion of the stem 9 through the hole 6.
  • the expansion 15, and optionally part of the cylindrical portion of the stem 9 is divided into at least two parts by a slot 16 that runs along a diametrical plane of the stem 9. These at least two parts, separated by the slot 16, can be cold-shaped elastically or plastically toward or away from the axis of the stem 9 in order to allow the insertion of the stem 9 through the hole 6 and/or to subsequently retain the expansion 15 inside the cap holder 3.
  • the receptacle 9 is provided as a through hole that passes through the entire supporting element 4.
  • the stem 14 of the tack that constitutes the fixing element 5 has a length that reaches, when inserted in the receptacle 11, the region occupied by the slot 16 so as to prevent deformation of the at least two parts into which the expansion 15 is divided towards the axis of the stem 9 and/or so as to cause the elastic or plastic deformation of these at least two parts of the expansion 15 away from the axis of the stem 9 when the fixing element 5 mates with the supporting element 4.
  • the button according to the invention is assembled and applied to an item of clothing as follows.
  • the supporting element 4 is preferably preassembled to the cap holder 3 by inserting the stem 9 through the hole 6.
  • the frustum-like shape of the expansion 15 causes a plastic or elastic flexing of the two parts into which the expansion 15 is divided by means of the slot 16 toward the axis of the stem 9. This flexing allows the expansion 15 to pass through the hole 6.
  • the cap 2, if provided, is then assembled, for example by seaming, to the top of the cap holder 3.
  • the cap holder 3, assembled with the supporting element 4 and the optional cap 2 is then positioned on one side of the fabric 12 of the item of clothing while the fixing element 5 is arranged coaxially to the receptacle 11 on the opposite side of the fabric 12.
  • the fixing element 5 is then pushed with its stem 14 into the seat 11, piercing the fabric 12.
  • the expansion of the end of the stem 9 of the supporting element 4, designated by the reference numeral 10a in this figure, can be achieved by hot or cold plastic deformation of said end of the stem 9 during the assembly of the supporting element 4 to the cap holder 3, or by molding the synthetic material of which the supporting element 4 is made directly during its manufacture by arranging the cap holder 3 in the mold.
  • the expansion 10a is constituted by an enlarged portion that has a larger diameter than the hole 6 and can have various shapes according to the requirements.
  • the button in a second embodiment thereof, has been generally designated by the reference numeral la and the parts of the button that correspond to those already described with reference to the preceding figures have been designated by the same reference numerals.
  • the cap holder 3 can slide along the stem 9 and can oscillate about the axis of the stem 9 with respect to the supporting element 4, achieving the intended mobility for the cap holder 3, as shown in particular in Figures 4 to 6.
  • the retention of the cap holder 3 performed by the expansion 10, 10a is such as to ensure the required strength of the button both during use and during treatments for finishing the item of clothing to which it is applied.
  • the button according to the invention frilly achieves the intended aim, since it can be assembled and applied to the item of clothing more simply than traditional kinds of swivel tack buttons.
  • the particular connection between the supporting element and the fixing element eliminates the operation for riveting the fixing element and does not require the use of a riveting element inside the cap holder even for buttons with a closed cap, thereby achieving considerable savings in production costs and eliminating the danger of cap damage.
  • Another advantage of the button according to the invention is that it has an extremely low noise level with respect to known kinds of swivel tack buttons.
  • the button thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims; all the details may further be replaced with other technically equivalent elements.
  • the materials used, so long as they are compatible with the specific use, as well as the dimensions may be any according to requirements and to the state of the art.
