Definitions
- a retractable ball point pen includes a barrel which houses a replaceable ball point cartridge which is slidably protractable and retractable and spring biased to a retracted position.
- a follower bears on the cartridge inner end and a clip member includes a bracket projecting through an upper slot in the barrel and having opposing inclined slots slidably and swingably engaging pivot projections on the upper faces of the follower.
- the lower end of the clip member includes a cam surface which engages the follower so that inward pressure on the follower lowers it to protract and latch the cartridge and the clip is provided with an arm projecting above the bracket and pressure on the arm swings the cam outwardly to release the follower and cartridge to their retracted positions.
- the present invention relates generally to improvements in writing implements and it relates more particularly to an improved retractable, replaceable cartridge ball point pen in which the advance and retraction of the writing element is effected by the simple manipulation of a clip member carried by the writing implement.
- propel-repel mechanisms employed and proposed for use in the protraction and retraction of the writing element in ball point pens but these have been generally of a complex nature or difficult and inconvenient to operate and frequently unreliable.
- propel-repel mechanisms which have heretofore been available or proposed is a type in which the advance of the writing element to its extended position is effected by the radial inward depression of a clip member carried by the pen. While such an arrangement is highly convenient, the associated mechanism possesses numerous drawbacks and disadvantages. It is generally complex, inconvenient to employ, or little reliability and commonly subject to malfunctioning and damage and otherwise leaving much to be desired.
- Another object of the present invention is to provide an improved replaceable cartridge ball point pen of the cartridge propel-repel type, in which the point is inherently withdrawn before the pen can be clipped in a pocket.
- a still further object of the present invention is to provide an improved protractable retractable ball point pen in which the advance end retraction of the writing element is effected by manipulation of a clip member carried by the pen.
- Yet another object of the present invention is to provide a device of the above nature characterized by its reliability, ruggedness, ease and convenience of operation, simplicity and low cost and high versatility and adaptability.
- a retractable writing implement comprising a barrel member, an elongated writing element disposed in the barrel member and longitudinally movable between a retracted position and an advanced position projecting through an opening at the bottom of the barrel, a spring urging and writing element to its retracted position, a follower longitudinally slidably disposed in the upper part of the barrel and in engagement with the upper part of the writing element, the barrel member having an opening registering with the follower and a clip mounted on the upper part of the barrel for swinging about a transverse axis between the top and bottom of the clip, the clip including upper and lower arms extending above and below the transverse axis, the lower arm having a cam at its lower end registering with the barrel opening and provided with an inwardly upwardly inclined downwardly facing cam face engaging an upwardly facing portion of the follower whereby inward swinging of the lower arm effects the downward movement of the follower and writing element and the outward swinging of the upper arm to an outward
- the follower is provided at its upper part with laterally axially aligned opposite pivot projections provided with outwardly converging end faces and a depending transversely offset pair of parallel transversely spaced arms joined by a bottom ledge projecting transversely toward the barrel opening.
- the clip includes a pair of laterally spaced bracket plates having inclined longitudinal slots slidably swingably engaging the pivot elements and the cam engages the upper face of the follower bottom ledge.
- the writing element extends longitudinally inclined to the vertical, between the follower spaced arms and into engagement with a downwardly facing surface at the upper part of the follower.
