Title: Spiral belt buckle in round material - with material wound over rectangular or square cross-section
Inventor: KURSCHILGEN FRANZ
IPC: A44B11/02
Filed: 1975-10-04
Abstract: The spiral belt buckle is in round material which is wound with approximately a 1 1/4 turn over a rectangular or square cross-section. The winding spacing between the two freely emerging shanks is shaped to draw in a belt. Specifically, instead of the square or rectangular basic profile of the spiral winding, a polygon or a circle or an oval or an ellipse is used as the basic profile. In practical installations, the end of the belt works against a torsion spring.

Title: Sliding clasp fastener end closure - has half sections which mate together and form a free tunnel zone for the slide
Inventor: ZOELLINGER BERNHARD GEORG
IPC: A44B19/36
Filed: 1977-04-01
Abstract: In a sliding claps fastener, where there is a manual closure at the end to join and separate the ends of the carrier bands, there is a tunne-shaped free space to take the slide.
