Miter box
A miter box includes, in a first direction, a through opening having a shape adapted to the cross-section of an element to be cut.
1. 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.
2. The miter box of claim 1 , wherein the miter box has a generally rectangular parallelepiped shape.
3. The miter box of claim 1 wherein the opening emerges onto both lateral surfaces.
4. The miter box of claim 1 , comprising a second slot following a plane perpendicular to the first direction, and a third slot following a plane forming a non-perpendicular angle with the first direction, wherein the first and third slots follow planes forming respective angles of plus 45 degrees and minus 45 degrees with the first direction.
5. The miter box of claim 4 , wherein the planes do not intersect each other within a volume of the miter box.
6. The box of claim 1 , wherein the slot emerges onto at least the upper, front and rear surfaces.
7. The box of claim 1 , further comprising a base in which the slot or slots stops.
8. The miter box of claim 1 , wherein the opening has a non-convex shape.
9. The miter box of claim 1 , wherein the opening has a lower, rectangular portion and an upper portion having a rounded shape, the upper portion adjacent the upper surface of box.
10. The miter box of claim 1 , comprising a second slot following a plane perpendicular to the first direction and having a second slot opening on the rear surface wherein the rib is positioned on the rear surface between the second slot opening and first slot opening.
11. 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.
12. The miter box of claim 11 , and further comprising a third, angled slot following a plane forming a respective angle of plus 45 degrees with the first direction, wherein the second slots follows a plane forming a respective angle of minus 45 degrees with the first direction.
13. The miter box of claim 12 , wherein the planes do not intersect each other within a volume of the miter box.
14. The miter box of claim 11 , wherein the through opening has a closed contour.
15. The miter box of claim 14 , wherein the through opening has a lower, rectangular portion and an upper portion having a rounded shape.
16. The miter box of claim 11 , wherein the slots emerge onto at least the upper, front and rear surfaces.
17. 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.
