Abstract
A taping knife which includes a blade with an elongated handle secured to the blade. The plastic handle includes a durable inner member and a grippable outer core. The hollow inner member is formed from adjoining member halves which have an inner structural support network of ribs. The handle component parts sealably interlock and are secured together upon formation of the outer grippable core whose material flows into certain ribbed network compartments and secures the interlocking parts together.
Claims21
A tapping knife, comprising:
- a blade member having a working blade region and a blade securement region;
- an elongated handle secured to said blade member in said securement region and extending distally from said blade member along the line of gripping, said handle including,
- (i) an inner member formed from a first plastic material, said inner member having distal and proximal ends;
- and
- (ii) an outer grip member formed of a second plastic material which surrounds a portion of said inner member to form a grippable area,
- said securement region including a backing plate secured to said blade and said handle being secured to said backing plate.
A taping knife, comprising:
- a blade member having a working blade area and a blade securement region;
- an elongated handle secured to said blade member in said securement region and extending distally from said blade member along the line of gripping, said handle having distal and proximal ends and further including,
- (i) a hollow inner member formed from a first plastic material, said inner member having distal and proximal ends and including two adjoining halves, each said half having an inside surface, an outside surface, and an outside wall;
- and
- (ii) a structural rib network on said inside surfaces of said inner member halves;
- and
- (iii) a hammering head formed from a hard, strong material having distal and proximal ends, said hammering head including a distal headcap and a tongue, said tongue extending proximally forward and including at least a pair of notches;
- and
- (iv) a slot in said distal end of said inner member for receiving said hammering head tongue;
- and
- (v) an outer grip member formed of a second thermoplastic rubber material which surrounds the grippable portion of said inner member;
- and
- (vi) at least one compartment formed by said structural ribs in said handle's distal end, said compartment including at least one access hole through said inner member halves, wherein
- (a) said tongue and said tongue notches extend proximally forward into said compartment;
- and
- (b) said outer grip material flows into and is forced through said compartment access holes, said material filling said inner member compartment and securely surrounding said hammering head tongue and said tongue notches.
