  • Chain keeper and method of retaining a chain
    Patent number: 7000292
    Abstract: A chain keeper for retaining a chain operatively connected to a driving mechanism of a chain hoist system. The chain keeper has a support bracket and a pair of plates. The support bracket is mountable onto a fixed structure, and has a substantially vertical longitudinal axis, and opposite top and bottom sections. Each plate has top and bottom portions. The plates project from the support bracket and are slanted with respect to the longitudinal axis thereof. The plates converge towards one another towards the bottom section of the support bracket, a slot being defined between peripheral edges of the plates at the bottom section of the support bracket. The slot is shaped and sized to slidably and removably receive therein a segment of the chain for retaining the same from substantial vertical movement along the longitudinal axis of the support bracket.
