Abstract
A saw guide for attachment to a portable, mechanical saw handle. The saw guide includes a substantially-rigid housing having a central cavity, expandably adjustable along at least one guide bar adapted to accommodate the handle. The housing defines a peripheral track channel. An elongate boom having a length is slidably mounted within the peripheral track channel, longitudinally extending outwardly from the track channel. A substantially-rigid finger member includes a base and is rotatably and slidably affixed about the boom. The finger member has a finger extending laterally from the boom beyond an extant of the housing. The finger member is selectively securable to the boom at a position along the length of the boom.
Claims17
A saw guide for attachment to a portable, mechanical saw handle, said guide comprising:
- a housing having a circular central cavity, the housing including a substantially rectangular first portion and a substantially rectangular second portion that expandably adjust relative to each other via two fasteners to accommodate the handle, the first portion defining a peripheral track channel extending therethrough along a width of said housing, and the first portion having a hollow central portion and an axial housing compressor extending within said first portion perpendicularly to said track channel;
- an elongate cylindrical boom having a length and slidably mounted within said peripheral track channel longitudinally extending outwardly from said track channel, wherein said boom has an adjustable state wherein said boom is positionally adjustable relative to the housing, and a fixed state wherein the position of the boom relative to said housing is fixed upon actuation of the housing compressor without the need for tools;
- and
- an L-shaped finger member having a base including a through-hole rotatably and slidably affixed about said boom, said finger member having a finger extension extending laterally from said base and said boom beyond an extant of said housing, and said finger extension is configured to engage an object to be cut, and said finger member having a finger compressor configured to selectively secure said finger member to said boom without the need for tools at a predetermined lateral position along the length of said boom and at an angular position about the boom;
- wherein the circular central cavity is defined by a semicircular recess in the first portion and a semicircular recess in the second portion that form a complete circle when the first and second portions are put together;
- wherein said track channel extends along the width of said housing through at least three quarters of the width of said housing to permit adjustment of said boom within;
- wherein the housing compressor and finger compressor are threaded fasteners having knurled knobs for facilitating gripping by a hand of a user;
- and
- wherein said finger extension includes a flat interior surface facing the housing and an opposed flat exterior surface, and said finger extension terminates in a rounded terminus surface.
6 more elements
A cutting system comprising:
- a portable, mechanical saw having radially actuating teeth about a guide blade, extending into a saw casing, having a length and height, said casing having a handle;
- and
- a saw guide comprising:
- a housing having a circular central cavity, the housing including a substantially rectangular first portion and a substantially rectangular second portion that expandably adjust adjustable along at least one guide bar relative to each other via two fasteners adapted to accommodate the handle, the first portion defining a peripheral track channel extending therethrough along a width of said housing, and the first portion having a hollow central portion and an axial housing compressor extending within said first portion perpendicularly to said channel;
- an elongate cylindrical boom having a length and slidably mounted within said peripheral track channel longitudinally extending outwardly from said track channel, wherein said boom has an adjustable state wherein said boom is positionally adjustable relative to the housing, and a fixed state wherein the position of the boom relative to said housing is fixed upon actuation of the housing compressor without the need for tools;
- and
- an L-shaped finger member having a base including a through-hole rotatably and slidably affixed about said boom, the finger member having a finger extension extending laterally from said base and said boom beyond an extant of said housing, and said finger extension is configured to engage an object to be cut, and said finger member having a finger compressor configured to selectively secure said finger member to said boom without the need for tools at a predetermined lateral position along the length of said boom and at an angular position about the boom, the finger extension having a first and a second flat opposed surfaces extending to a distal end of the finger extension, the first surface facing the housing and the second surface facing away from the housing;
- wherein the circular central cavity is defined by a semicircular recess in the first portion and a semicircular recess in the second portion that form a complete circle when the first and second portions are put together;
- wherein said track channel extends through at least three quarters of the width of said housing to permit adjustment of said boom within, and along a width direction of said housing;
- wherein the housing compressor and finger compressor are threaded fasteners having knurled knobs for facilitating gripping by a hand of a user;
- and
- wherein said finger extension includes a flat interior surface facing the housing and an opposed flat exterior surface, and said finger extension terminates in a rounded terminus surface.
