Abstract
A jigsaw is provided including a housing and a drive mechanism disposed within the housing. The drive mechanism is provided with a mechanical connection for selectively imparting a reciprocating, scrolling and/or orbital motion to a drive shaft of the jigsaw and/or to a saw blade attached to the drive shaft of the jigsaw during use thereof. The jigsaw includes a support member for selective engagement with a part of the saw blade to provide support to the blade during the reciprocal, scrolling and/or orbital motion.
Claims47
A jigsaw, said jigsaw including a housing and a drive mechanism disposed within said housing, said drive mechanism being provided with a mechanical connection for selectively imparting a reciprocating, scrolling and/or orbital motion to a drive shaft of the jigsaw and/or a saw blade attached to the drive shaft of the jigsaw during use thereof, and wherein said jigsaw includes a support member for selective engagement with a part of said saw blade to provide support to said blade during said reciprocal, scrolling and/or orbital motion.
A reciprocating cutting tool configured for orbital cutting, comprising:
- a housing;
- a power source disposed in said housing;
- a main linkage connected to said power source and to a blade for driving the blade in a vertically reciprocating motion;
- a foot plate connected to said housing and including a portion in operational proximity to the blade;
- and
- a swivel bracket connected to said foot plate and disposed to exert a force to a rear edge of the blade.
An electric jigsaw, comprising:
- a housing;
- a power source disposed within said housing;
- a main linkage disposed within said housing and connected to said power source;
- a plunger secured within said housing and connected to said linkage for reciprocating, pivotal and rotational movement, and having an end configured for receiving a blade;
- and
- a selector mechanism for selecting between said pivotal and said rotational movement of said plunger, and including a swivel bracket mechanism selectively positioned to exert a force to a rear edge of the blade and cause said plunger to exhibit pivotal movement;
- wherein said pivotal movement relates to orbital blade motion, and said rotational movement relates to scrolling blade motion.
An electric jigsaw, comprising:
- a housing;
- a power source disposed within said housing;
- a main linkage disposed within said housing and connected to said power source;
- a plunger located within said housing and having an end configured for receiving a blade, said plunger being connected to said linkage and being capable of generally vertical reciprocating movement, rotational scrolling movement and orbital movement;
- and
- a selector mechanism for alternatively selecting scrolling and orbital movement, said selector mechanism having a rocker member selectively positioned to exert a force to a rear edge of the blade.
An electric jigsaw having scrolling and orbital operational capability, comprising:
- a housing;
- a motor in said housing;
- a generally vertical elongated reciprocating plunger to which a blade can be attached at its lower end;
- a drive mechanism interconnecting said motor and said plunger and supporting said plunger to facilitate reciprocating, scrolling and orbital movement, said mechanism being configured to exert a force to an attached blade during orbital operation;
- and
- a selector mechanism for alternatively selecting scrolling and orbital operation.
