Coupling between shaft element and part

Abstract

 The invention concerns the coupling of a shaft element (1) with a synthetic material part (3). With constructions like sunshades the bones are consisting of shaft elements, in many cases round bars reinforced with glass fibre, on which synthetic material elements like pivots are have to be fixed. For this purpose a slit (2) is made in the bone and a pivot element which is foreseen of an integrated peg (6) where the peg (6) is secured with a locking ring (8).

Description

[0001] The invention concerns the coupling of a shaft element with a synthetic material part. With constructions like sunshades the bones are consisting of shaft elements, in many cases round bars reinforced with glass fibre, on which synthetic material elements like pivots are have to be fixed. In most cases these are labour intensive operations.
The invention concerns a coupling between the bar shaped bone and synthetic material parts like pivot elements. For this purpose a slit is made in the bone and a pivot element which is foreseen of a integrated peg where the peg is secured with a locking ring.

[0002] The invention is explained with the help of the drawing.

Fig. 1 shows the shaft element with slit.

Fig. 2 shows the cross section over the shaft element.

Fig. 3 shows the synthetic element with peg.

Fig. 4 shows the cross section over the synthetic element with peg.

Fig. 5 shows cross section over locking ring.

Fig. 6 shows face of the locking ring.

Fig. 7 shows the cross section over the mounted element.

[0003] In Fig. 1 is (1) the shaft element with slit (2). Slit (2) defines the position where synthetic element (3) is mounted. Synthetic element (3) is foreseen with opening (4) where shaft element (1) fits in. Synthetic element (3) is foreseen of a notch (5) in which the peg (6) which is molded on. Notch (5) is so deep that peg (6) falls into slit (2). Peg (6) has the form of notch (5) and is connected with synthetic material element (3) by a thin part (7) permitting peg (6) to pivot. Around synthetic element (3) fits a locking ring (8). Locking ring (8) is foreseen with notches (9) where cams (10) fit in when locking ring (8) is pushed over synthetic element (3). Locking ring (8) fixes then peg (6) by which synthetic element (3) is fixed to shaft element (1).

Claims

1. Coupling between shaft element and synthetic material element characterised by that the synthetic element (3) is foreseen with a molded-on peg (6) which is fitting in slit (2) of shaft element (1) where peg (6) is locked with locking ring (8).

2. Coupling as per claim 1 characterised by that peg (6) is connected with a thin part (7) to synthetic material element (3).

3. Coupling as per claim 1 and 2 characterised by that locking ring (8) is fixed by cams (10) and notches (9).
