ABSTRACT:
A window operator handle foldable between an operable position for manual pivoting and a storage position, including a body with a manually graspable portion at one end and a recess in the other end, and a base including a longitudinal cylindrical portion having a central bore extending completely through the base. The handle body recess is defined by side walls spaced a selected width, a top wall, and a wall at one end oriented substantially parallel to the operator drive shaft when the handle is in the operable position, with the base cylindrical portion having an outer diameter slightly less than the selected width. An operator drive shaft is securable in the base bore so that the an outer end of the drive shaft is substantially adjacent the handle body when the handle is in a storage position. The handle base is secured for pivoting relative to the handle body about an axis substantially orthogonal to longitudinal whereby in the storage position the base is substantially within the handle body recess. The body top wall serves as a stop for pivoting of the base relative to the body when the handle is pivoted to the storage position and the body end wall serves as a stop for pivoting of the base relative to the body when the handle is pivoted to the operable position. A detent on the handle base is sharply tapered at one end, with the detent itself being narrower than the recess selected width by a selected amount. A detent spring has two legs connected at one end by a spring base secured at the other end of the handle body. In an unbiased position, the other ends of the spring legs are spaced apart less than the width of the detent, with those leg ends having a total width which is less than the selected amount and engaging the detent tapered end when the handle is in the operable position.
