(54) | Dual-operation handle device |
(57) The present invention provides a duel-operation handle device comprising a base with
rotating shafts, and a main operation handle and a coupler mounted on one of said
rotating shafts wherein said main operation handle and coupler are provided with mated
projecting edges so that when said main operation handle is operated to turn around
the rotating shaft, said coupler will be driven by said mated projecting edge to turn
around the rotating shaft. Said duel-operation handle further comprises an ancillary
operation handle which is arranged concentrically with said main operation handle
and is provided with at least one tooth. Said coupler is further provided with at
least one tooth to engage with the tooth of said ancillary operation handle so that
when said ancillary operation handle is operated to turn around the rotating shaft,
said coupler will be driven by said engaging teeth to turn around the rotating shaft.
Said linkage mechanism connected with the coupler can be driven by only operating
the ancillary operation handle, without operating said main operation handle or affecting
the current state of said main operation handle.
