Portable handheld powered envelope opener with grip handle

A portable, handheld envelope opening device comprising:

• a housing having a head portion and a handle portion;
• said head portion including a slot defined by a pair of opposing walls and a base plate, said walls being spaced so as to guide the passage of an envelope therebetween;
• a pair of rotary discs disposed within said head portion adjacent said base plate and intersecting in partially overlapping fashion along a centerline of said slot spaced from and proximate to said base plate;
• said first disc including a cutting edge, and said second disc is adapted urge the envelope into engagement with the first cutting disc adjacent an edge of the envelope to sever a marginal edge of the envelope to expose the contents therein;
• a motor disposed within said handle portion;
• a gearbox assembly coupled to said discs for transferring power from the motor, said gearbox assembly also comprising a plurality of step gears arranged coaxially along at least two axes to simultaneously drive said pair of discs at a reduced speed relative to said motor;
• a compartment for containing one or more batteries to energize said motor;
• and
• a switch disposed on the outside of said handle portion for electrically coupling the drive means to said one or more batteries to energize said drive means.

A portable, handheld envelope opening device comprising:

• a housing having a head portion and a handle portion;
• said head portion including a slot defined by a pair of opposing walls and a base plate, said walls being spaced so as to guide the passage of an envelope therebetween;
• at least a portion of one or more of said pair of opposing walls is angled slightly from parallel to the centerline of said slot to form a tapered insertion opening for guiding an envelope into the slot more easily;
• a pair of rotary discs disposed within said head portion adjacent said base plate and intersecting in partially overlapping fashion along a centerline of said slot spaced from and proximate to said base plate;
• said first disc including a cutting edge, and said second disc having a serrated edge to urge the envelope into engagement with the first cutting disc adjacent an edge of the envelope to sever a marginal edge of the envelope to expose the contents therein;
• said pair of discs each slightly tilted in planes intersecting at an oblique angle with said base plate so as to urge the envelope into contact with said base plate;
• a motor disposed within said handle portion;
• a gearbox assembly coupled to said discs for transferring power from the motor, said gearbox assembly also comprising a plurality of step gears arranged coaxially along at least two axes to simultaneously drive said pair of discs at a reduced speed relative to said motor;
• one or more batteries to energize said motor;
• a switch disposed on the outside of said handle portion for electrically coupling the drive means to said one or more batteries to energize said drive means;
• and
• wherein said first disc having an undulating peripheral edge causing the margin edge of the envelope to have a wave profile after cutting the envelope by passing it through the slot.
