Abstract
A writing instrument having a casing with an axially-extending bore seating a cantilevered arm of a pocket clip which protrudes through the casing bore when the instrument is in an "off" position. The pocket clip has guide tabs which fit into guide channels in the instrument's casing. The guide channels, with spring fingers which bias the pocket clip in the direction of the bore, are capable of releasably locking the clip in plural positions. In the "off" position the pocket clip arm protrudes through the casing aperture but the writing members housed within the casing are retracted. Moving the pocket clip to a "write" position causes a writing member to project from either the front or back of the housing and the pocket clip arm to be retracted into the casing.
Claims15
A writing instrument comprsing,
- at least one writing member,
- a tubular casing housing said writing member, said casing having a casing axis and an axially-extending lateral slot and having a front end and a back end, said front end having an opening,
- a slidable pocket clip having a cantilevered arm retractably extending from said lateral slot parallel to said casing axis, said writing member being in contact with said pocket clip, said pocket clip having a plurality of guide tabs , said cantilevered arm extending from a first side of said pocket clip and said guide tabs extending from at least one side of said pocket clip perpendicular to said first side,
- structure having recesses defining recessed guide channels associated with said casing, said guide channels disposed to slidably accept said guide tabs whereby motion of said pocket clip moves said writing member in an axial direction, said guide channels having a configuration to secure said socket clip in at least two positions including a first write position wherein said cantilevered arm is retracted into said lateral slot and a first writing member extends from said opening of said front end, and
- a biasing means for urging said pocket clip in a direction substantially perpendicular to said casing axis to releasably lock said pocket clip in said positions.
A writing instrument comprising,
- a first writing member,
- a tubular casing movably housing said first writing member, said casing having a lengthwise axis and having a front portion and a rear portion, said front portion having an opening at a tip, said casing having a lateral slot extending parallel to said axis,
- a slidable pocket clip having a cantilevered arm retractably extending from said lateral slot parallel to said axis, said first writing member being axially movable in said front portion of the casing and having an extremity in contact with said pocket clip, said pocket clip having a plurality of guide tabs, said cantilevered arm extending from a first side of said pocket clip and said guide tabs extending from at least one side of said pocket clip perpendicular to said first side,
- a plurality of recessed guide channels associated with said casing, said guide channels disposed to accept said guide tabs of the pocket clip whereby motion of said pocket clip moves said first writing member in an axial direction,
- biasing means for urging said pocket clip in a direction substantially perpendicular to said casing axis, and
- a means for releasably locking said pocket clip in at least two positions, said pocket clip having a first write position wherein said cantilevered arm is retracted into said lateral slot and said first writing member has a head extending from said opening of the casing front portion, said pocket clip having an off position wherein said cantilevered arm extends from said casing and said first writing member is retracted into said casing, said means for releasably locking said pocket clip including a first write position stop in at least one guide channel.
