  • Patent number: 5636417
    Abstract: A curtain hook comprises a plastic strip (41) and an I-section (42, 43, 44) which is integral therewith and in which the flange (42) facing the strip is provided with at least one sawtooth profile (48), while the other flange (43) is a guide for a runner (45) which grips around it, and to which a hook-shaped element (46) is connected. The runner has at least one projection (47) which engages in the sawtooth profile (48) in order to prevent the runner from being moved in a certain direction, while movement of the runner in the opposite direction is still possible. In order to simplify sewing of the curtain hook into a curtain pleat by machine, the abovementioned other flange (43) of the I-section is narrower than a flange (42) facing the strip.
