Description

Connector for attaching a button to a fabric backing

The innovation concerns eluent connectors for fastening a button on a fabric backing; it is marked by a flexible piece of thread with a known sequence of locking teeth that is attached to a End of a needle point and at the other end a known closure piece with a through opening and having locking means for the piece of thread.

The innovation differs from known connectors with a piece of thread and a locking piece, such as those used for holding together cable harnesses, primarily in that one end of the piece of thread has a needle tip which enables a material to be pierced. The new connector also differs in its dimensions, especially in the very small thickness of the piece of thread: Only these decisive changes make it possible to use the connector, which is known in principle, for attaching buttons to fabric supports * Ba 1 Sur / 11/14/1979 *

Dae Fadenetüek is preferably made of a very flexible plastic and can have locking teeth along its entire length) these can have a substantially sawtooth profile in the longitudinal direction of the Fadenstüekes or simply be formed as spherical thickenings. Zweokmttßigerwejse then 1st the first section of Fädenstüokes of the closure member without locking teeth ausgebildetj When sewn button, this smooth Fadenstüok on the outside of the knob so that the impression of a normal sewing state "

Fadenetüek and pin portion may be integrally formed "with the needle tip may go bed also made of a harder material than the Fadenetüek $ itself in the latter case, the needle tip stoffsohlüsslg with the piece of yarn connected.

The needle tip can, however, also be designed as a special metal part and connected to the thread piece in a form-fitting manner be; this can be done by opening the tip of the needle projecting end of the thread piece be thickened. This embodiment has the advantage that a Injury with the needle point is hardly possible, so that you have the free, piece protruding from the end end does not necessarily need to cut off the piece of thread »

In a preferred embodiment of the innovation, the thread piece and the closure piece are made in one piece from plastic be trained. The opening of the closure piece for the piece of thread has preferential locking means Γ have resilient flanks that spring into the incision between two successive locking teeth; the dimensions and elastic forces are so dimensioned that the piece of thread can be pulled out

the passage opening is only possible with the application of force is how §ie with normal use of the button never occurs. So if you have a borrowed fastening want to connect with a reliable bracket, the locking teeth will have a sawtooth profile give steep trailing edges.

An embodiment of the innovation is explained with reference to the figures, they show - each in an enlarged view Representation - i

Pig. 1 a longitudinal view of the new connector, Fig. 2 is a plan view of the Versehlußätüek the connector (in the direction of arrow II in Fig. 1) and

Fig. 3 shows the connection between a button and a Fabric underlay with a connector in accordance with the innovation.

The thread piece of the connector is denoted by 1 and here has sawtooth-shaped locking teeth 11 in the longitudinal profile. At one end, the piece of thread merges into a needle point 2; at the other end, it has a closure piece 3 with a passage opening 31.

Between this locking piece 3 and the end of the locking teeth 11, the thread piece has an area 12 free of locking teeth.

To attach the button 5 to the St off pad 4 the connector with the needle point 2 through the fabric backing encountered, the locking piece 3 at the same time serves as a stop that prevents the connector from being pulled through the fabric. After threading the button 5, the needle point 2 is again pierced through the fabric base 4 and then through the passage

opening 351 out in the Versehlußstüek. The connector is then tightened, with the locking teeth stretching the passage opening 31 through this until the button 5 only has the game required for use, the connection in cross section al has approximately the appearance shown in FIG. 3. On the button surface, only the section 12 free of locking teeth can be seen, which - with the appropriate coloring - can hardly be seen from an ordinary thread differs.

The part protruding beyond the locking piece 3 of the piece of thread 1 is separated after about two locking teeth.
