  • Latch needle with a fixed spring
    Patent number: 6510714
    Abstract: A latch needle (1) has a leaf spring (8, 8′) that is associated with the latch (4), that is disposed in the sawslot (3) and is held in corresponding bearing seats (14, 15) at the narrow sides or end walls (11, 12) defining the sawslot 3. Each bearing seat (14, 15) has a support surface (18) for the respective end of the spring, and at least one counterpart surface (21), with the respective end (16, 17) of the leaf spring (8) extending between these two surfaces and being held there. The axial or longitudinal play of the leaf spring (8, 8′) is so small that the leaf spring (8, 8′) cannot fall out of the space between the support surface (18) and the counterpart surface (21), even when it is deflected to a considerable extent. The leaf spring (8, 8′) is therefore held securely in the sawslot (3).
