Collapsing blade
View Patent ↗A collapsing blade comprising an upper and lower handle section joined at the rear by pivotal means; a set of arms pivoted upon the lower handle section, a rear blade pivoted on the upper handle section by means of an embracing body; a front blade comprising a hollow portion and an edged portion pivotally attached to said arms and rear blade; wherein by angular rotation of handle sections the blade assembly is arranged from collapsed to extended configurations.
1. A collapsible blade comprising:
a frame construction, said frame construction comprising two handle sections joined at their respect rears by a pivot;
a forward blade and rear blade pivotally connected to each other;
a set of arms pivoted on a lower of the two handle sections, wherein said arms are capable of occupying folded and extended positions; wherein when the arms are in their folded positions they are confined within the handle sections;
wherein the forward blade is pivotally connected to the arms;
wherein when the collapsible blade is in a fully folded configuration, the forward blade is located internally between the two handle sections and movement of the frame away from the forward blade extends said arms and creates a quadrilateral configuration of the two handle sections, the arms and the rear blade; and
wherein continued movement of the two handle sections pivotally towards each other after reaching the quadrilateral configuration causes the collapsible blade to have a fully extended and lockable position.
2. The collapsible blade of claim 1 , wherein each handle section has two respective halves and confinement of the arms within the handle section includes placement of the arms in between the two halves.
