Claims17
A miter box comprising front and rear opposing surfaces, two opposing lateral surfaces, and an upper surface, wherein one lateral surface includes in a first direction, a through opening having a closed contour and a shape adapted to the cross-section of an element to be cut, the miter box further comprising a slot defining a cut line entirely crossing the opening,
- characterized in that a rear surface of the miter box comprises a first slot opening and a protruding rib, approximately vertical, for aiding positioning of the box for angle cuts, wherein the slot follows a plane forming a non-perpendicular angle with the first direction, and wherein the protruding rib is arranged offset from the first slot opening and in a middle of a projection of the slot on the rear surface.
A miter box comprising front and rear opposing surfaces, two opposing lateral surfaces, and an upper surface, wherein one lateral surface includes, in a first direction, a through opening having a shape adapted to the cross-section of an element to be cut, the miter box further comprising a first slot following a plane perpendicular to the first direction, and a second, angled slot following a plane forming a respective angle of either plus 45 degrees or minus 45 degrees with the first direction, wherein rear surface of the miter box comprises a first slot opening, an angled slot opening, and a protruding rib, approximately vertical, for aiding positioning of the box for angle cuts, and wherein the protruding rib is arranged offset from the first slot opening and in a middle of a projection of the angled slot on the surface between the first slot opening and the angled slot opening.
A miter box comprising:
- front and rear opposing surfaces, two opposing lateral surfaces, and an upper surface;
- a through opening having a closed contour and a shape adapted to the cross-section of an element to be cut, the through opening accessible on the lateral surfaces and having a lower, rectangular portion and an upper portion adjacent the upper surface having a rounded shape;
- and
- three cut slots each defining a cut line entirely crossing the through opening, the three slots including a first slot following a plane perpendicular to the first direction, second slot following a plane forming a respective angle of plus 45 degrees with the first direction, and a third slot following a plane forming a respective angle of minus 45 degrees with the first direction,
- wherein the slots emerge onto at least the upper, front and rear surfaces.
