Abstract
A power hand tool foot assembly includes a platform having an arch portion. A swivel lock is within the arch portion, with a mount connecting the swivel lock to the tool housing. A lever is pivotally mounted on the mount. When the lever is in a locked position, the swivel lock and platform are locked in place. When the lever is in an open position, the longitudinal and angular position of the platform and swivel lock may be adjusted.

A foot assembly for a power hand tool of the type that has a housing with a greater lengthwise dimension than its width, the foot assembly comprising:
- a platform with a bottom planar surface around a substantial part of its outer periphery and a curved arch portion, said arch portion having at least one opening for use in attaching said platform to the housing;
- a swivel lock at least partially within said arch portion, said swivel lock having a pair of sidewalls, at least one opening and being moveable in a longitudinal direction relative to the housing;
- a mount passing through said arch portion opening and said swivel lock opening and connected to the tool housing;
- and,
- a lever pivotally held on said mount, said lever having a cam defined between two lever sidewalls, said cam lever sidewalls configured to be pivotally held within said swivel lock pair of sidewalls, said lever configured to lock said platform and said swivel lock in place when said lever is pivoted in a direction towards said platform to cause said cam to engage said swivel lock to thereby sandwich said swivel lock and said arch portion in place between the tool housing and said lever cam.
A tiltable portable jigsaw foot for a jigsaw of the type that has a housing with a lengthwise direction greater than its width and a reciprocating blade, the foot assembly comprising:
- a platform movable along the longitudinal direction of the jigsaw and tiltable relative to the housing, said platform having a generally curved arch portion, first and second openings extending through said arch portion;
- a swivel lock at least partially within said arch portion and having an opening therethrough, said swivel lock having a rear edge and a restraining arm engaging said arch portion upper wall second opening;
- a threaded bolt passing through said swivel lock opening and through said arch portion first opening, said threaded bolt removably attached to the jigsaw;
- a yoke removably held on said threaded bolt;
- and,
- a lever pivotally held on said yoke and having an eccentric cam, said lever operable to cause said eccentric cam to hold said swivel lock in place, said lever having at least one locking formation for abutting said swivel lock rear edge.
A portable electric jigsaw comprising:
- a housing containing a motor;
- a reciprocating blade linked to said motor;
- and,
- a foot assembly connected to said housing and having:
- a platform with a bottom planar surface around a substantial part of its outer periphery and a curved arch portion, said arch portion having a first opening configured to provide longitudinal travel of said arch portion and said platform relative to said housing and tilting of said platform relative to said housing, said arch portion having a second opening;
- a swivel lock at least partially within said arch portion, said swivel lock having a slot, said swivel lock having a locking arm engaging said arch portion second opening;
- a mount passing through said arch portion first opening and said swivel lock slot and adjustably connected to the tool housing;
- and
- a lever pivotally held on said mount, said lever configured to lock said platform in place.
A foot assembly for a power hand tool of the type that has a housing with a greater lengthwise dimension than its width, the foot assembly comprising:
- a platform with a bottom planar surface around a substantial part of its outer periphery and a curved arch portion, said arch portion having a front edge and at least one opening for use in attaching said platform to the housing;
- a swivel lock at least partially within said arch portion, said swivel lock having at least one opening and having a restraining arm configured to engage said arch portion front edge;
- a mount passing through said arch portion opening and said swivel lock opening and connected to the tool housing;
- and,
- a lever pivotally held on said mount, said lever configured to lock said platform in place.
A foot assembly for a power hand tool of the type that has a housing with a greater lengthwise dimension than its width, the foot assembly comprising:
- a platform with a bottom planar surface around a substantial part of its outer periphery and a curved arch portion with a generally semi-cylindrical shape and first and second openings, said first opening having a transverse cross portion and a longitudinal stem portion, said second opening comprising a slot extending along a portion of the perimeter of said arched portion;
- a swivel lock at least partially within said arch portion, said swivel lock having at least one opening and having a restraining arm engaging said slot;
- a mount passing through said arch portion first opening and said swivel lock opening and connected to the tool housing;
- and,
- a lever pivotally held on said mount, said lever configured to lock said platform in place.
