Press-stud fastening that can be adjusted on a support layer

Abstract

Known adjustable press-stud fastenings ( 10 ) consist of at least two complementary press-stud parts, namely a male and female part ( 11, 12 ), which can be snapped together for producing a connection. At least one press-stud part ( 11 ) is attached to a support layer ( 19 ) using a connecting piece ( 21 ). The other press-stud part ( 12 ) can likewise be connected to a support layer ( 20 ) using a connecting piece ( 21 ), or can be connected directly thereto ( 20 ). The adjustable press-stud fastening ( 10 ) allows the support layers ( 19, 20 ) to be superimposed, by the connection of the male part ( 11 ) to the female part ( 12 ). Said superimposition can be modified by the adjustable press-stud fastening ( 10 ). The connecting piece ( 21 ) must be capable of adapting to its support layer ( 19 ) in order for the press-stud fastening ( 10 ) to be additionally used for articles of clothing, such as jackets, trousers etc. In addition, the invention aims to provide a simple and secure adjustment of the press-stud fastening ( 10 ). To achieve said aims, the connecting piece ( 21 ) consists of a flexible material, enabling it to follow a deformation of the support layer ( 19 ) and complementary locking means are provided in the connecting piece ( 21 ) and in an indirectly positioned press-stud part ( 11 ), enabling a permanent, secure positioning of the press stud part ( 11 ) onto the connecting part ( 21 ). In addition, said press-stud fastening ( 10 ) should consist of a small number of parts that are simple to produce.
