Claims16
A sharpener system for pencils having a core, said system comprising two or more component sharpeners, each component sharpener comprising a separate housing having top and bottom walls and a fitting means that is disposed on at least one side of each housing, and a complementary fitting means that is disposed on a side of each housing that is opposite to the side having said fitting means, said fitting means and said complementary fitting means for interconnecting with each other, said top and bottom walls and the two sides defining a pencil channel, wherein two or more component sharpeners are selectively attachable by engaging the respective fitting means and complementary fitting means on the sides of each separate housing.
In combination, at least two sharpeners for use with pencils that encase a core, each sharpener comprising an essentially cuboid sharpener housing having a front wall with a pencil entry opening, a rear wall with an outlet, top and bottom walls and a pair of longitudinal lateral walls (6, 7) which define a pair of side walls for the sharpener housing (1), said top and bottom walls and said side walls defining a pencil channel, wherein said side walls are provided with complementary protrusion and recess means which enable interconnecting said side wall for one sharpener housing with at least one side wall of a sharpener housing of another sharpener, characterized in that said pair of longitudinal lateral walls (6, 7) are provided with said protrusion and recess means comprising longitudinal or cross ribs and intermediate grooves, wherein the shape and thickness of respective longitudinal or cross ribs (8, 8', 8", 8'") on one side wall corresponds to the shape and thickness of respective intermediate grooves (9, 9', 9", 9'") on the opposite side wall.
In combination, at least two sharpeners for use with pencils that encase a core, each sharpener comprising an essentially cuboid sharpener housing having a front wall with a pencil entry opening, a rear wall with an outlet, top and bottom walls and a pair of longitudinal lateral walls (6, 7) which define a pair of side walls for the sharpener housing (1), said top and bottom walls and said side walls defining a pencil channel, wherein said side walls are provided with complementary protrusion and recess means which enable interconnecting said side wall for one sharpener housing with at least one side wall of a sharpener housing of another sharpener, characterized by said protrusion and recess means comprising knobs (8"") provided on one of said side walls (6), and receiving sleeves (9"") provided on another of said side walls (7).
In combination, at least two sharpeners for pencils which encase a core, each sharpener comprising:
- a housing comprising laterally opposed side walls and top and bottom walls, said side walls and top and bottom walls defining a pencil channel;
- and
- a fitting means disposed on at least one side wall of said housing that is capable of mating with a complementary fitting means that is disposed on at least one side wall of another sharpener housing, said fitting means and said complementary fitting means for interconnecting said housing and said another sharpener housing;
- wherein each sharpener housing is substantially cuboidal and said fitting means comprises at least one of longitudinally extending ribs and grooves.
In combination, at least two sharpeners for pencils which encase a core, each sharpener comprising:
- a housing comprising laterally opposed side walls and top and bottom walls, said side walls and top and bottom walls defining a pencil channel;
- and
- a fitting means disposed on at least one side wall of said housing that is capable of mating with a complementary fitting means that is disposed on at least one side wall of another sharpener housing, said fitting means and said complementary fitting means for interconnecting said housing and said another sharpener housing;
- wherein each sharpener housing is substantially cuboidal and said fitting means comprises at least one of laterally extending ribs and grooves.
In combination, at least two sharpeners for pencils which encase a core, each sharpener comprising:
- a housing comprising laterally opposed side walls and top and bottom walls, said side walls and top and bottom walls defining a pencil channel;
- and
- a fitting means disposed on at least one side wall of said housing that is capable of mating with a complementary fitting means that is disposed on at least one side wall of another sharpener housing, said fitting means and said complementary fitting means for interconnecting said housing and said another sharpener housing;
- wherein said sharpener housing is substantially cuboidal and said fitting means comprises one or more protruding buttons and said complementary fitting means comprises one or more sleeves for receiving said buttons.
