Definitions

  • the invention relates to a reversible ball for snap fasteners of sheet material, consisting of one spherical part and one in each Ball part insertable plastic molding on both sides of the surface material, the spherical parts and the molded plastic parts are each identical and each plastic molded part has a flange for contact with the Underside of the ball part and a shaft for insertion into the ball part and the ball parts can be inserted into a rivet hole in the shafts Rivets can be connected to each other and to the surface material.
  • Reversible balls designed in this way for snap fasteners known with a plastic molded part inserted into the ball part.
  • Such Reversible balls are particularly suitable for attachment to waterproof Surface material used because the plastic molded part inserted into the ball part in the riveted state the passage of water through the Should prevent rivet connection. It happens with these known turning balls however, again and again that when riveting between the plastic molding and form cavities on the inside of the spherical part, so that despite Use of a water-impermeable surface material through the water Rivet connection from the outside in to the garment or the like can reach.
  • the invention has for its object to provide a turning ball for pushbuttons that is completely waterproof in the riveted state and beyond also holds the required stripping forces stand.
  • the outer surface of the shaft of each plastic molded part is substantially adapted to the inner shape of a spherical part, the shaft is extended out of the spherical part via the flange and the rivet is designed as a hollow rivet open at both ends .
  • a reversible ball designed according to this technical teaching has the advantage that the plastic molding due to its design adaptation to the Inner shape of the ball part inserted almost self-sealing into the ball part can be made without voids between the plastic molding and the Remain inside the sphere.
  • the sealing effect of the plastic molding is further increased by the fact that the hollow rivet is designed as open at its ends Rivet inside the spherical parts by flanging extending radially Rivet heads, which additionally counteracts the plastic molded parts press the inside surfaces of the balls.
  • the extension of the shaft of the plastic molded parts beyond the flange provides an additional seal between the surface material and the turning ball and on the other hand it provides a guide to start the rivet shaft when riveting the two spherical parts with the surface material
  • the rivet hole has of the shaft at its free end lying inside the spherical part recessed paragraph on which to accommodate the when riveting the ball parts resulting rivet head is used.
  • a circumferential groove extends on the free end. Based on these Material reduction in the area of the circumferential groove indicates the surface material end of the shaft facing some flexibility, which the overpressure described above is prevented.
  • a circumferential, bulge-like bulge is formed on the rivet shaft of the rivet.
  • This bulge formed from the wall material of the hollow rivet facilitates the formation of indentations and protuberances when riveting on both sides of the bulge, which on the one hand means that when riveting necessary length compensation is effected and on the other hand in the area of protrusions forming the plastic molded part additionally sealing is pressed against the inner surface of the ball.
  • the on both sides of the Bulging portions of the rivet shank are of different lengths.
  • a turning ball essentially of two ball parts 1, two Plastic molded parts 2, which are used in the spherical parts 1, and a rivet 3 for connecting the two with the plastic molded parts 2 Ball parts 1.
  • Fig. 1a to Fig. 1c is the assembly of a spherical part 1 with a plastic molded part 2 shown.
  • the ball part 1 consists of a flange 1a and a Ball head 1b, which for receiving in the (not shown) eyelet one Push button serves.
  • the plastic molding 2 shown in Fig. 1b which to form a watertight connection - as shown in Fig. 1c - Is inserted into the ball part 1, has a flange 2a, a shaft 2b and a rivet hole 2c for receiving the rivet 3.
  • a transverse surface 2d closing the rivet hole 2c is arranged in the rivet hole 2c.
  • the outer surface of the Shaft 2b essentially the inner shape of the spherical part 1 - in particular in Area of transition from flange 1a to ball head 1b - adapted. On in this way it becomes almost a self-sealing seal between the molded plastic part 2 and spherical part 1 ensures that there are no voids between form the plastic molded part 2 and the inside of the spherical part 1, through which water could pass through the riveted joint.
  • FIG. 2a to 2c show the connection of one with a plastic molded part 2 provided ball part 1 with a rivet 3.
  • the rivet 3 shown in Fig. 2a is designed as a hollow rivet open at both ends, which is approximately in the middle of the Rivet shaft 3a has a circumferential, bulge-like bulge 3b.
  • To the Riveting the rivet 3 with the ball part 1 rivets 3 into the rivet hole 2 of the molded plastic part 2 and then in the interior of the spherical part 1 pressed. In this riveting process, the rivet 3 pierces the transverse surface 2d and becomes so when it hits the inner surface of the ball head 1b flanged that a rivet head 3c forms.
  • the rivet hole 2c has at its free, in Inside the ball part 1 lying end a recessed paragraph 2e on.
  • the depth of this recessed paragraph 2e is dimensioned so that on the one hand the formation of the rivet head 3c by the material of the Shaft 2b is not hindered, but on the other hand enough shaft material in the area of the rivet head 3c it remains that the rivet head 3c which forms Shafts 2b sealingly presses against the inner surface of the ball head 1b.
  • Fig. 3 shows a turning ball shortly before riveting.
  • Surface material 4 for example a water-impermeable fabric
  • a ball part 1 with a plastic molded part 2 inserted therein is arranged, which are connected to each other and to the surface material 4 via the rivet 3 should be.
  • the free end of the rivet shaft 3a pressed against the sheet material 4 so that it presses into the rivet hole 2c and bears against the transverse surface 2d closing the rivet hole 2c.
  • the transverse surface 2d has the task of passing the surface material 2 through Press with the end of the rivet shaft 3a when piercing the sheet material 4 with the rivet shaft 3a to prevent it from sliding back.
  • Fig. 4 shows a reversible ball connected to a surface material.
  • the two spherical parts 1 with the plastic molded parts arranged therein 2 firmly and waterproof connected via the rivet 3.
  • the riveted State are formed in both ball heads 1b rivet heads 3c, on the one hand the watertight pressing of the molded plastic part 2 onto the inner surface ensure the spherical part 1 and on the other hand ensure that the Reversible ball withstands the pull-out forces required when loosening the Turning ball occur from the (not shown) eyelet of a push button.
