Abstract
A window operator is disclosed. The window operator may be provided with a handle that may be folded from an operable (or extended) position to a stored (or retracted) position. In the window operator, a spring assembly having an integrally formed spring finger operates within a cavity in the body of the handle of the window operator to provide a securing (or positive locking) action at least in an operable position. The spring assembly may also provide a securing action in the stored (or storage) position.
Claims28
A window operator having a handle securable to a window operator drive shaft, the handle moveable from a first position to a second position, the handle comprising:
- a spring assembly configured to engage the window operator drive shaft and the spring assembly having a spring integrally formed with the spring assembly;
- a body assembly having a first end with a manually graspable portion and a second end with a cavity formed to hold the spring assembly;
- and
- a pivot coupling the spring assembly and the body assembly in pivotal relation to each other.
A handle for a window operator, the handle securable to a window operator drive shaft, the handle moveable from a first position to a second position, the handle comprising:
- a spring assembly configured to engage the window operator drive shaft and the spring assembly having a spring integrally formed with the spring assembly;
- a body assembly having a first end with a manually graspable portion and a second end with a cavity formed to hold the spring assembly and the cavity having a first detent and a second detent to provide a positive indication of handle positioning relative to the window operator;
- and
- a pivot coupling the spring assembly and the body assembly in pivotal relation to each other,
- wherein the spring engaging the first detent, releasably secures the handle in the first position and the spring engaging the second detent, releasably secures the handle in the second position.
A handle for a window operator, the handle securable to a window operator drive shaft, the handle moveable from a first position to a second position, the handle comprising:
- a spring assembly having a bore extending partially through the spring assembly, the bore configured to accept the window operator drive shaft and the spring assembly having a spring integrally formed with the spring assembly, the spring being a flexible cantilevered member with an engagement end;
- a body assembly having a first end with a manually graspable portion and a second end with a cavity formed to hold the spring assembly and the cavity having a first detent and a second detent to provide a positive indication of handle positioning relative to the window operator, the first and second detent configured to engage with the engagement end of the spring;
- and
- a pivot pin, coupling the spring assembly and the body assembly in pivotal relation to each other,
- wherein the engagement end of the spring engaging the first detent, releasably secures the handle in the first position and the engagement end of the spring engaging the second detent releasably secures the handle in the second position, and the first and second detents providing a positive tactile indication that the handle is in the respective position.
