Manually-operated implement suitable for cleaning flat surfaces, especially glass sheets

Abstract From the Canadian patent

The invention relates to a hand implement for cleaning flat surfaces, especially glass. The implement comprises a holder for a replaceable sponge and a wiper blade. A handle is attached to the casing via two superposed joints which allow the handle to be tilted and laterally adjusted relative to the holder. Locking mechanisms are provided to hold the handle in the desired tilted and laterally adjusted position, the locking being releasable by pressure on the handle against a spring. The implement allows the handle to be firmly retained in the desired position but, permits the handle to be adjusted using one hand when, desired.
