Abstract:
A pair of replaceable scissors blades without handles, secured together with a pivot structure for attachment and removal as a unit with respect to a support and a blade actuator, comprising:a first blade with a cutting portion, a mounting portion and a first pivot-receiving aperture in the mounting portion, a second blade with a cutting portion, an actuating portion and a second pivot-receiving aperture between the two portions of the second blade, a pivot structure connecting the first and second blades through said pivot-receiving apertures, said pivot structure having a first element that is wider than said first pivot-receiving aperture and engages an outer surface of said first blade and has a clamping surface facing away from said first blade, said pivot structure having a second element that is wider than said second pivot-receiving aperture and engages an outer surface of said second blade, said elements being interconnected, such that said first and second blades are secured together by said pivot structure for relative pivoting about the pivot structure independently of any support structure and independently of any actuating structure, said pivot structure defining an aperture extending through said first and second elements and being surrounded by the clamping surface and through which said blades may be secured to a support by way of the pivot structure, said actuating portion of the second blade having a slot extending at an obtuse angle with respect to a general extent of the cutting portion of the second blade, and said mounting portion of the first blade having two locating apertures at approximately diametrically opposed locations relative to the first pivot-receiving aperture and spaced from each other in a direction transverse to a general extent of the first blade and a distance greater than the maximum width of the cutting portion of the first blade.
