Folding window operator handle

A handle securable to a window operator drive shaft for selectively manually pivoting said operator drive shaft, said handle being foldable between an operable position for manual pivoting and a storage position, said handle comprising:

• a handle body having two ends with a manually graspable portion at one end and a recess in its other end, said recess being defined by body side walls spaced a selected width, a body top wall, and a body end wall at said other body end oriented substantially parallel to the operator drive shaft when the handle is in the operable position;
• a handle base including a cylindrical portion extending in a longitudinal direction and having an outer diameter slightly less than said selected width;
• means for securing a window operator drive shaft in said cylindrical portion;
• means secured to one side of the cylindrical portion for securing the handle base for pivoting relative to the handle body about an axis substantially orthogonal to said longitudinal direction, said body top wall serving as a stop for pivoting of the base relative to the body when the handle is pivoted to the storage position and said wall at one end serving as a stop for pivoting of the base relative to the body when the handle is pivoted to the operable position;
• a detent releasably securing said handle base relative to said handle body when said handle is in its operable position and when said handle is in its storage position.

A handle securable to a window operator drive shaft for selectively manually pivoting said operator drive shaft, said handle being foldable between an operable position for manual pivoting and a storage position, said handle comprising:

• a handle body having two ends with a manually graspable portion at one end and a recess in its other end, said recess being defined by body side walls spaced a selected width, a body top wall, and an end wall at one recess end oriented substantially parallel to the operator drive shaft when the handle is in the operable position;
• a handle base including a cylindrical portion extending in a longitudinal direction and having an outer diameter slightly less than said selected width;
• means for securing a window operator drive shaft in said cylindrical portion;
• means secured to one side of the cylindrical portion for securing the handle base for pivoting relative to the handle body about an axis substantially orthogonal to said longitudinal direction, said body top wall serving as a stop for pivoting of the base relative to the body when the handle is pivoted to the storage position and said wall at one end serving as a stop for pivoting of the base relative to the body when the handle is pivoted to the operable position;
• a detent releasably securing said handle base relative to said handle body when said handle is in either its operable position or its storage position, wherein said detent comprises:
• a detent portion secured to one of the body or base at an end of the recess opposite the one recess end, said detent portion being narrower than the recess selected width by a selected amount and having a tapered end;
• a detent spring fixed to the other of the body or base, said spring having an engaging portion having a width less than said selected amount and engaging said detent portion tapered end when the handle is in the operable position;
• and
• means for biasing said engaging portion of said spring around said detent portion tapered end when the handle is manually biased from its operable position toward its storage position.

A handle securable to a window operator drive shaft for selectively manually pivoting said operator drive shaft, said handle being foldable between an operable position for manual pivoting and a storage position, said handle comprising:

• a handle body having two ends with a manually graspable portion at one end and a recess in its other end, said recess being defined by body side walls spaced a selected width, a body top wall, and an end wall at one recess end oriented substantially parallel to the operator drive shaft when the handle is in the operable position;
• a handle base including a cylindrical portion extending in a longitudinal direction and having an outer diameter slightly less than said selected width;
• means for securing a window operator drive shaft in said cylindrical portion;
• means secured to one side of the cylindrical portion for securing the handle base for pivoting relative to the handle body about an axis substantially orthogonal to said longitudinal direction, said body top wall serving as a stop for pivoting of the base relative to the body when the handle is pivoted to the storage position and said wall at one end serving as a stop for pivoting of the base relative to the body when the handle is pivoted to the operable position;
• and
• a detent releasably securing said handle base relative to said handle body when said handle is in its operable position or its storage position, wherein said detent includes
• a detent portion secured to one of the body or base at an end of the recess opposite the one recess end, said detent portion being narrower than the recess selected width by a selected amount and having a tapered end,
• a detent spring fixed to the other of the body or base, said spring having an engaging portion having a width less than said selected amount and engaging said detent portion abutting end when the handle is in the operable position,
• means defining a taper between the engaging portion of the spring and said detent portion abutting end whereby said taper means causes the engaging portion of the spring to spread clear of the abutting end when said handle is firmly biased from its operable position to its storage position, and
• means for biasing said engaging portion of said spring around said detent portion tapered end when the handle is manually biased from its operable position toward its storage position.

A handle securable to a drive shaft of a window operator for selectively manually pivoting said operator drive shaft, said handle being foldable between an operable position for manual pivoting and a storage position, said handle comprising:

• a handle body with a manually graspable portion at one end and a recess of a selected width in said other end;
• a handle base including
• a main body portion having a width slightly less than said selected width, one end of said main body portion having a drive shaft bore completely therethrough and the other end having a pivot bore therethrough substantially orthogonal to said drive shaft bore, and
• a detent on said main body portion one end, said detent being narrower than the selected width by a selected amount and having a tapered end;
• means for securing a window operator drive shaft in said base drive shaft bore;
• means for pivotally securing the handle body to the handle base main body portion pivot bore whereby in said storage position said base is substantially within said handle body recess;
• a generally U-shaped detent spring having two legs connected at one end by a spring base,
• the other ends of said legs in an unbiased spring position spaced apart less than the width of the detent, and
• the other ends of each of said legs having a total width which is less than the selected amount;
• and
• means for securing said spring at its base in said handle body recess with said leg other ends abutting the detent tapered end when the handle is in its operable position.
