Abstract:
1. A coupling release component for releasabley coupling a shaft of a motor to a further shaft for rotation of the further shaft by the motor shaft comprising: a rotation lock means comprising axially disposed first gripping means for connecting the lock means to the shaft of a motor for inducing rotation of said lock means by said motor, a slip coupling means comprising second gripping means disposed radially outwardly relative to the first gripping means configured to releasabley interlock with a corresponding third gripping means of a further coupling means for connecting the coupling release component to said further shaft for the rotation thereof, and resilient mounting means mounting said second gripping means to said first gripping means so as to be able to exert a radially outward force on the second gripping means so as to radially bias the second gripping means into interlocking engagement with the third gripping means, wherein the second gripping means and the corresponding third gripping means are configured such that when a predetermined rotational force sufficient to overcome the radially outward bias of the resilient mounting means is produced by the motor, the interlocking between the second and third gripping means is released such that the second gripping means slips in relation to the further coupling means.
