Definitions

  • the invention is directed to a watertight snap fastener part or press fastener part formed of an eyelet part comprising an eyelet body or of a ball part comprising a ball body, each of which has an axial opening, and a cap rivet which is fixable to a flat material, preferably in the form of a breathable or weatherproof or climate membrane, in a watertight manner by riveting, with an elastically deformable sealing element which makes contact at the flat material and is constructed as a molded part, wherein the sealing element, being penetrated by the rivet shank of the cap rivet, has in the assembled state due to the deformation of the rivet shank a press face which is formed in an analogous manner by deformation and which surrounds the axial opening of the press fastener part and, together with a counter-face at the eyelet part or at the ball part, defines the clamping area for the flat material.
  • the sealing element which is formed by an intricately shaped plastic disk and, at the underside of the cap rivet, forms a stationary component part of the latter has a central bore hole which is penetrated by the rivet shank, but which comprises a caplike cover, wherein the rivet shank reaches up to the latter.
  • the eyelet part When riveting with the eyelet part formed in the shape of a bar spring die, the eyelet part, after penetrating the flat material, engages in a front-side annular groove of the sealing element by a socket-like rivet shank receptacle which terminates in an annular edge that is rounded on the radial inside and forms the opening of the eyelet part, wherein the annular groove of the sealing element is coaxial to the rivet shank and adjoins the caplike cover.
  • This annular groove is surrounded concentrically by an annular projection formed integral therewith as a front-side press face.
  • climate membranes of greater dimensions e.g., three-ply laminates or laminates comprising a stronger woven fabric, for example, comprising loden wool.
  • a known construction of a watertight ring loop for footwear in which the rivet shank end which tapers to a point is constructed in a closed manner makes use of a sealing element having a sleeve-shaped portion and an annular disk-shaped portion which extends radially outward following the sleeve-shaped portion.
  • an upper and lower press fastener part (DE 37 42 007 C) which comprises a watertight rivet cap whose shank penetrates through a flat material during pressing and is driven into a plastic part constructed in the form of a spherical part or eyelet part so as to be fixed to this flat material.
  • This fixation method is also not suitable for fixing press fastener parts to thicker flat material.
  • a press fastener connection is known (EP 0 401 574 A) in which the press fastener part formed by a ball part is fixed to the flat material by a cap rivet with a rivet shank which tapers to a point and is constructed in a closed manner, which rivet shank initially penetrates a sealing ring of elastic material before it penetrates the flat material and engages in the interior of a molded sheet-metal body forming the ball part and having a hat-shaped elastic plastic inserted in this molded sheet-metal body.
  • the flat material When the rivet shank is pressed, a widening of the tip area of the rivet shank takes place and the flat material is tensioned in the area between the edge of the hat-shaped elastic plastic and the sealing ring, especially in the area of the outer zone of the hat-shaped molded sheet-metal body and that of the edge of the cap rivet.
  • the flat material undergoes a similar clamping in the construction in which the press fastener part is formed by an eyelet part. In both cases, the holding force by which the flat material is grasped is not sufficient to fix thicker material so securely that there is no risk of tearing out.
  • the press fastener part according to the invention in which this object is met is essentially characterized in that the sealing element comprises a sleeve-like portion followed by a radially outwardly extending annular disk-shaped portion, in that the sleeve-like portion of the sealing element is provided in the region of its free edge with a radially outwardly directed reinforcement forming a circumferentially extending undercut and the latter is provided with a circumferentially extending bevel facilitating assembly, proceeding from the end face of the free edge and facing the annular disk-shaped portion, and in that this sealing element, for purposes of preassembly, can be mounted on the eyelet body forming the eyelet part or on the ball body forming the ball part in such a way that it penetrates the axial opening of the eyelet body or the axial opening of the ball body, respectively, with its sleeve-shaped portion and, when subsequently riveted with the rivet shank of the cap rivet guided through the sleeve-shaped portion, contacts by its
  • the sealing element has, from the outset, to the fullest extent the end shape in the sealing area after placement. Also, when mounted on thicker climate membranes, a fixed hold is ensured even in the event of extensive stresses or loading.
  • a feature that has proven especially favorable consists in that the sealing element is provided in the sleeve-shaped area receiving the rivet shank with a circumferentially extending edge formed by a reduction in diameter, wherein a rounded mouth facilitating the insertion of the rivet shank and flat material leads to this circumferentially extending edge. This edge prevents the flat material, once it has been drawn in, from being pulled back again and assists the dependability of the aimed for water tightness.
  • a construction that has proven especially effective with respect to securing a fixed hold of the flat material in the area of the rivet shank bore hole consists in that the free end of the sleeve-shaped portion of the sealing element is deformed into a position in which it is bent by almost 180° outward and backward while being carried along by the outer end of the rivet shank during pressing accompanied by fixation of the flat material pierced through by the rivet shank.
  • the circumferentially extending bevel proceeding from the end face of the free edge of the sleeve-shaped portion of the sealing element and facing the annular disk-shaped portion is constructed so as to be rounded on the outside.
  • the sleeve-shaped portion of the sealing element is connected with the annular disk-shaped portion by means of a connecting portion which, together with the sleeve-shaped portion, defines a circumferentially extending free groove serving to receive the end of the eyelet shank.
  • a particularly durable fixation of the press fastener part formed by an eyelet part with respect to the flat material results when a radially extending transition area follows the holding area of the eyelet part, which holding area extends coaxial to the sleeve-shaped portion of the sealing element, wherein, after the pressing of the eyelet part with the rivet shank, the transition area supports the annular disk-shaped portion of the sealing element and holds it in position pressing against the underside of the rivet cap accompanied by fixed clamping of the flat material.
  • the press fastener part is formed, on the one hand, of an eyelet part 1 comprising an eyelet body 2 or of an eyelet part 3 comprising an eyelet body 4 or of a ball 5 with a ball body 6 and, on the other hand, of a cap rivet 7 which can be fixed in a watertight manner to a flat material 9, preferably in the form of a climate membrane, with the eyelet part or the ball part by riveting by means of its rivet shank 8.
  • the rivet shank 8 penetrates an axial opening 10 of the eyelet part 1 or 3 or of the ball part 5.
  • a sealing element 11 or 12 is associated with the eyelet part or ball part. This sealing element 11 or 12 contacts the flat material, is elastically deformable and is constructed as a molded article.
  • the sealing element 11, 12 has a sleeve-shaped portion 15 followed by a radially extending, annular disk-shaped portion 16.
  • the sleeve-shaped portion 15 of the sealing element 11 is connected with the annular disk-shaped portion 16 by means of a connecting portion 17 which defines a circumferentially extending free groove 18 with the sleeve-shaped portion 15. It is the function of this groove 18 when the sealing element 11 is mounted with the eyelet part 1 to receive the end 19 of the eyelet body 2, which end 19 is bent inward and backward in a semicircular manner.
  • the sleeve-shaped portion 15 of the sealing element 11 comprises at its free edge 20 a circumferentially extending bevel 21 facing the annular disk-shaped portion 16.
  • this bevel 21 is constructed so as to be rounded on the outside.
  • the sleeve-shaped portion 15 of both constructions of the sealing element 11, 12 according to Figs. 1 and 2 is provided in each instance with a reinforcement which faces radially outward and forms a circumferentially extending undercut 22, wherein the bevel 21 extends toward the reinforcement.
  • the sealing element 11 is provided in the sleeve-shaped portion 15 receiving the rivet shank 8 with a circumferentially extending edge 23 formed by a diameter reduction, wherein a rounded mouth 24 which facilitates the insertion of the rivet shank and flat material during pressing leads to this circumferentially extending edge 23.
  • annular disk-shaped portion 16 directly adjoins the sleeve-shaped portion 15 of the sealing element 12 so as to extend roughly at right angles relative to it.
  • the eyelet part or ball part 1, 3 or 5 terminates in a holding portion 25 which engages behind the undercut 22 of the sleeve-shaped portion at the outer side of the sleeve-shaped portion 15.
  • a radially extending transition area 26 adjoins the holding portion 25 of the eyelet part, which holding portion 25 extends coaxial to the sleeve-shaped portion 15 of the sealing element 12. After the pressing of the eyelet part with the rivet shank 8, this transition area 26 supports the annular disk-shaped portion of the sealing element and holds it so as to be pressed against the underside of the rivet cap while fixedly clamping the flat material 9.
  • a ball part area 27 which is insertable into the eyelet part 3 and cooperates with the latter follows the holding portion 25 of the ball part 5, which holding portion 25 extends coaxial to the sleeve-shaped portion 15 of the sealing element 12. After the pressing of the ball part 5 with the rivet shank 8, this coaxially undulant ball area 27 holds the annular disk-shaped portion 18 of the sealing element 12 in a position pressed against the underside of the rivet cap accompanied by deformation and with fixed clamping of the flat material 9.
