Abstract
A blade guide for a hair clipper bladeset, the guide configured for slidable engagement in a transverse track of a stationary blade, and including a blade guide body having a first edge and a second edge being generally parallel to and spaced from the first edge, each of the edges having a pair of opposed free ends. At least one arched load beam connects a corresponding opposed pair of the free ends of the first and second edges for exerting a torsion-resisting biasing force between the edges.
Claims18
A blade guide for a hair clipper bladeset having stationary and moving blades, said guide comprising:
- a blade guide body having a first edge and a second edge being generally parallel to and spaced from said first edge, each of said edges having a pair of opposed free ends, said body defining a longitudinal axis extending parallel to, and between said first and second edges;
- and
- at least one arched load beam connecting a corresponding opposed pair of said free ends of said first and second edges, said beam being arched in a plane defined by said guide body, defining a space between said beam and said body along said longitudinal axis and being configured for exerting a laterally directed, torsion-resisting biasing force between said edges, said force exerted by said beams being directed in said plane and against opposing inside surfaces of said free ends;
- wherein said guide is a separate, detachable component from both the moving blade and the stationary blade and is configured for slidable engagement relative to the stationary blade in a recessed track of the stationary blade.
A blade guide for a hair clipper bladeset having stationary and moving blades, the stationary blade having a recessed track with spaced vertical edges, said guide comprising:
- a blade guide body having a first edge and a second edge being generally parallel to and spaced from said first edge, each of said edges provided with at least one contact pad for following a corresponding edge of the track, said body defining a longitudinal axis extending parallel to, and between said first and second edges;
- and
- at least one arched load beam spaced from said blade guide body along said longitudinal axis of said body, and connecting opposing contact pads of said first and second edges to resiliently bias said pads away from each other to resist torsional misalignment of a moving blade attached to said body as said body reciprocates in the recessed track relative to the stationary blade;
- wherein said guide is a detachable, separate component from both said moving blade and said stationary blade, is free of teeth and is configured for slidable engagement in the track of the stationary blade.
A hair clipper bladeset, comprising:
- a stationary blade having a toothed edge and an upper surface defining a recessed transverse track having opposed edges;
- a moving blade with a toothed edge and an underside defining a guide recess;
- a blade guide provided with a blade guide body having a first edge and a second edge being generally parallel to and spaced from said first edge, said body defining a longitudinal axis extending parallel to, and between said first and second edges, each said blade guide edge having a pair of opposed free ends, each of said blade guide edges configured for slidably engaging said opposed edges of said recessed track in said stationary blade;
- and
- at least one arched load beam spaced from said blade guide body along said longitudinal axis of said body, connecting opposed inside surfaces of a corresponding opposed pair of said free ends of said first and second blade guide edges and being constructed and arranged for exerting a compression-resisting biasing force between said blade guide edges such that said edges are biased against corresponding edges of said transverse track once said blade guide is slidably engaged in said track for maintaining proper alignment of said moving blade relative to said stationary blade during operational reciprocation of said moving blade relative to said stationary blade.
