Abstract
A snap-on handle structure for attachment to an operating shaft having detent notches and cam members including a handle with an internal recess, and a generally U-shaped spring member in the handle recess with a pair of spaced-apart arms with free ends extending toward an open end of the recess. Each of the arms has a generally V-shaped hook portion intermediate the central base of the spring member and the free ends of said legs with a pair of inclined legs to coact with the cam members on placement of the handle on the operating shaft and coaction with the detent notches for retention of the handle on the shaft.
Claims5
A snap-on handle structure including a handle with an internal recess and an operating shaft with a series of raised splines each having a sloped end to form a cam surface and a detent notch intermediate the ends thereof, a generally U-shaped spring member secured to the handle and positioned in said recess with a pair of spaced-apart arms with outwardly diverging free ends extending toward an open end of the recess, each of said arms having a generally V-shaped hook portion spaced from said free ends to define a pair of inclined legs engageable in a pair of said detent notches, one of said legs of each pair acting to hold said handle on the shaft against removal and the other leg of each pair engaging said cam surface on a spline to deflect said hook portion as the handle is placed on the shaft.
A snap-on handle structure including a handle with an internal recess having a wall, an operating shaft with detent notches and a sloped cam surface with the latter disposed adjacent an end of the operating shaft, and a generally U-shaped spring member secured to said handle and positioned in said recess with a pair of spaced-apart arms with outwardly diverging free ends extending toward an open end of the recess and engaging said wall, each of said arms having a generally V-shaped hook portion spaced from said free ends and spaced from said recess wall to define a pair of inclined legs engageable in a pair of said detent notches, one of said legs engaging said cam surface to deflect said arms and the hook portions outwardly toward said wall as the handle is placed on the shaft and the other of said legs engaging the detent notch to hold the handle on the shaft against removal and with said free ends still outwardly diverging after handle placement on the shaft.
