Abstract
A print wheel mounting assembly for a daisy type print element comprising a generally circular disc section coupled to the hub of the print element, a generally cylindrical section, an end cap section pivotally coupled to the cylindrical section and having a shaft portion extending at right angles therefrom and back toward the hub of the print element and a coil spring positioned around the generally cylindrical section with the end portions positioned such that when the shaft portion of the end cap is inserted therebetween, the coil spring is tightened around the generally cylindrical portion to clamp the print element firmly to the shaft of the print element motor.
Claims4
In a daisy wheel print element having a plurality of spokes extending radially outward from a central section, character slugs having a print surface and an impact surface and coupled to the ends of the spokes, said central section having an opening centered therein for mounting the print element on a shaft of a print wheel motor;
- an improved print element mounting assembly comprising:
- a generally circular disc section having a central opening and being coupled to the central sectin and positioned coaxially with the opening in the central section,
- a generally cylindrical section having a central opening and being coupled at one end to the generally circular disc section and positioned coaxially with the opening in the central section,
- a coil spring having at least one turn positioned around the periphery of the generally cylindrical section, and coil spring having two end portions which extend radially from the generally cylindrical section and are spaced apart a predetermined distance,
- means for tightening the spring around the generally cylindrical section, said tightening means having an end cap section pivotally coupled to one edge portion of the end of the generally cylindrical section which is positioned furthest from the central section in an axial direction, said end cap section having a portion which extends in a radial direction beyond the outer periphery of the generally cylindrical section, said extended portion having a shaft extending at right angles therefrom back toward the central section of the print wheel, said shaft having a cylindrical section coupled to a tapered section increasing in peripheral distance which is coupled to a tapered section decreasing in peripheral distance, said end cap section being positioned such that the shaft is capable of being inserted between the two end portions of the coil spring to spread the end portions apart,
- whereby the print wheel is clamped to the shaft of the print wheel motor.
