Title:
HOSE CLAMP AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2013/118251
Kind Code:
A1
Abstract:
The pinching operation performed on both end parts is facilitated. A hose clamp (H1) is formed by bending a strip-shaped plate material (1) to a ring shape, and the hose clamp (H1) has a first end part (5) having a first pinching operation surface (9) and a second end part (6) having a second pinching operation surface (15). A through hole (7) is formed at a position towards the center in the longitudinal direction of the first pinching operation surface (9). When the plate material (1) is being bent to a ring shape, expanded regions (19) of the second pinching operation surface (15), which are arranged on both side sections with respect to the width direction, are folded at fold edges (20) with respect to the base region (18), whereby the second pinching operation surface (15) is narrowed in the width direction and is made capable of entering the through hole (7) in this state. After the plate material (1) is bent to a ring shape, the expanded regions (19) of the second pinching operation surface (15) are unfolded at the fold edges (20) and completely regain a widened state.
