A rotatable handle that is securable to a drive shaft of a casement window to thereby actuate said casement window, said rotatable handle being moveable between a stowed position and an operating position, said operating position being a position suited to actuate said casement window through rotation of said handle, said handle comprising:

• a body housing, said body housing comprising one or more walls that form a cavity;
• said body housing having a first end and a second end;
• an assembly body, said assembly body comprising one or more walls to form a cavity;
• said assembly body having a first end and a second end;
• said one or more walls permitting said assembly body to be mounted within said body housing;
• a pivotal member, said pivotal member comprising an opening in a bottom of said pivotal member for receiving a casement window drive shaft;
• said pivotal member being pivotally mounted within said assembly body cavity, proximate to said first end;
• said pivotal member further comprising a protrusion that protrudes outward from a first side of said pivotal member;
• a sliding member, said sliding member being slidably mounted within said cavity of said assembly body, between said pivotal member and said second end of said assembly body;
• said sliding member comprising a convex surface adjacent to a concave surface to create an apex, said convex surface transitioning into an end surface, said end surface comprising a recess;
• a spring means, said spring means biasing said sliding member relative to said assembly body to maintain contact between said sliding member and said pivotal member;
• and
• wherein when said rotatable handle is in said stowed position, said recess in said biased sliding member engages said protrusion of said pivotal member, said rotating handle thereby remaining in said stowed position until being pivoted into said operating position;
• and
• wherein when said rotatable handle is pivoted from said stowed position towards said operating position, said sliding member pivots relative to said pivotal member causing said recess to disengage from said protrusion;
• said convex surface of said pivotal member thereafter contacting said protrusion until said apex contacts said protrusion;
• said convex surface of said sliding member then being biased to contact a top surface of said pivotal member while in said operating position;
• both said biasing, and said apex of said sliding member co-acting with said protrusion of said pivotal member, serving to maintain said rotating handle in said operating position until said handle is pivoted back into said stowed position.

A rotatable handle that is securable to a drive shaft of a casement window to thereby actuate said casement window, said rotatable handle being moveable between a stowed position and an operating position, said operating position being a position usable to actuate said casement window through rotation of said handle, said handle comprising:

• an assembly body, said assembly body comprising one or more walls to form a cavity;

• said rotating handle remaining in said stowed position until being pivoted into said operating position;
• and
• wherein when said rotatable handle is pivoted from said stowed position towards said operating position, said sliding member pivots relative to said pivotal member with said convex surface contacting said protrusion until said apex passes over said protrusion;
• said convex surface of said sliding member being biased to contact a top surface of said pivotal member while in said operating position;
• said rotating handle being maintained in said operating position until said handle is deliberately pivoted back to said stowed position, said handle being maintained in said operating position by said biasing and by said apex of said sliding member co-acting with said protrusion of said pivotal member.
