Abstract
The present invention relates to a media cutting tool for use with a template. The apparatus of the present invention maintains proper alignment with a template through the use of a novel offset, rotating, cutting blade and guards against skipping along the cut as the apparatus is drawn around a template through the use of a novel guide mechanism which engages the template being traced. The present invention also employs a transparent handle for an improved view of the cutting area.
Claims9
A template tracing cutter that is configured to cut a thin medium, said cutter comprising:
- a blade having a cutting edge for cutting said medium, wherein said blade is coupled to a guide shaft having a first centroidal axis, and wherein said guide shaft is coupled to a stem having a second centroidal axis, said first centroidal axis being offset from and parallel to said second centroidal axis, and wherein said first centroidal axis and said second centroidal axis extend through a handle of said template tracing cutter;
- and
- a guide mechanism coupled to said blade, said guide mechanism comprising:
- said stem pivotably coupled to said handle, wherein said stem pivots on an axis of rotation that is coaxial to said second centroidal axis to rotate a trailing edge of said blade about said second centroidal axis;
- and
- said guide shaft having an axis of rotation coaxial with said second centroidal axis such that rotation of said guide shaft causes said trailing edge of said blade to swivel relative to said second centroidal axis in response to a friction force created within said thin medium during cutting to automatically align said blade in a direction that is parallel with a template.
A template tracing cutter that is configured to cut a thin medium, said cutter comprising:
- an automatically aligning blade with a cutting edge for cutting said thin medium;
- a guide mechanism coupled to the blade, wherein the guide mechanism includes a stem and guide shaft for following a template while cutting said thin medium, said guide shaft having a first centroidal axis and said stem having a second centroidal axis, wherein said first centroidal axis is offset from and parallel to said second centroidal axis, and wherein said first and second centroidal axes extend through said stem, said guide shaft, and through a handle coupled to said guide mechanism, and wherein said cutting edge includes a cutting point that is offset from and capable of rotating about the second centroidal axis;
- and
- a double offset configuration defined by said offset of said cutting point and said second centroidal axis to cause said blade to continuously align in a direction parallel to said template during cutting.
A template tracing cutter that is configured to cut a thin medium, said cutter comprising:
- a blade having a cutting edge for cutting said medium, wherein said blade is coupled to a guide shaft having a first centroidal axis, wherein said guide shaft is coupled to a stem having a second centroidal axis, and wherein said first and said second centroidal axes extend through said stem, said guide shaft, and through a handle of said template tracing cutter;
- and
- a guide mechanism coupled to said blade, said guide mechanism comprising:
- said stem coupled to said handle;
- and
- said guide shaft pivotably coupled to said handle, wherein said guide shaft pivots outside of said handle on an axis of rotation that is coaxial to said second centroidal axis to rotate a trailing edge of said blade about said second centroidal axis and cause said trailing edge to swivel relative to said second centroidal axis in response to a friction force created within said thin medium during cutting to automatically align said blade in a direction that is parallel with a template.
