Claims18
A writing instrument comprising a writing member disposed in a housing wherein said housing includes a top part configured to define a laterally open cavity with axially parallel cavity side walls, said cavity extending from an upper side portion to a top portion of said top part;
- said top part further being configured to define a clip recess extending axially along a side portion thereof from said cavity toward a bottom portion of said top part;
- a movable clip member mounted in said top part comprising an enlarged clip head with axially parallel clip head side walls received in said cavity and an elongated clip portion extending substantially parallel to the axis of said writing instrument, and
- guide means comprising inter-engaging elongated ribs and grooves arranged on said cavity side walls and on said clip head side walls at an acute angle to the axis of said writing instrument for guiding said movable clip member along an oblique path between a retracted position in which said clip portion is received in said clip recess and an extend position in which said clip portion is spaced away from said top part, whereby said clip member is prevented from pivoting and said clip portion remains at all times substantially parallel to the axis of said writing instrument.
A writing instrument comprising a writing member disposed in a housing wherein said housing includes a top part configured to define a laterally open cavity with axially parallel cavity side walls, said cavity extending from an upper side portion to a top portion of said top part;
- said top part further being configured to define a clip recess extending axially along a side portion thereof from said cavity toward a bottom portion of said top part;
- a movable clip member mounted in said top part comprising an enlarged clip head with axially parallel clip head side walls received in said cavity and an elongated clip portion extending substantially parallel to the axis of said writing instrument;
- guide means arranged on said cavity side walls and on said clip head side walls at an acute angle to the axis of said writing instrument for guiding said movable clip member along an oblique path between a retracted position in which said clip portion is received in said clip recess and an extended position in which said clip portion is spaced away from said top part, and
- an end piece insertable into said laterally open cavity through its lateral opening and secured in said cavity to said top part, said end piece including a stop portion which engages said movable clip member when said clip member is moved toward said extended position to limit the travel of said movable clip member in the direction of said extended position and retain said clip head in said cavity.
