Definitions

  • This invention concerns the connection of a shell-like front plate together with a locking plate. Both parts are made of hard plastic and are manufactured by means of a mass-production process like injection moulding and they can be used as an identification carrier or button
  • This production method has the disadvantage that socalled " Click-in-rims", when ejecting from the mould, cannot be applied when using hard plastic material.
  • hard plastics have little or no elasticity through which the flexible rim of the click-in connection either becomes extremely vulnerable or can hardly or not at all be realised.
  • the locking plate (1) has a number of swellings (2) around the circumference.
  • the size measured over the swellings (2) is larger than the receiving opening (3) in the front plate (4).
  • This opening (3) in the front plate (4) is provided with a roughened surface at the cylindrical part (5), preferably by means of sparkerosion. As soon as the locking plate (1) is being pressed into the front plate (4) the following occurs.
  • connection avoids the locking plate (1) from turning in the front plate (4).
  • the locking plate (1) can be equipped with slots (6) by means of which safety-pins f.e. can be attached. Between the front plate (4) and the locking plate (1) an interjacent element (7) can be locked in.
  • the mecanical connection is not limited to round elements only.

Abstract

Une liaison mécanique entre deux éléments en plastique (une plaque frontale et une plaque de fermeture) réalisée par des renflements (2) situés autour du bord de la plaque de fermeture et par une surface rugueuse (5) située dans la plaque frontale. La plaque de fermeture est prévue (6) pour faciliter le montage d'une épingle de sûreté. Un espace libre est ménagé pour un élément (7) disposé entre la plaque frontale et la plaque de fermeture.
