Dual operating mode plastic fastener dispensing handtool
View Patent ↗A dual operating mode hand tool for dispensing plastic fasteners and a method for transitioning the hand tool from a first operating mode to a second operating mode is provided. The hand tool tagging gun can be used both to dispense a plastic fastener to attach labels, price tags or other items to articles, and also to dispense a plastic fastener to maintain certain articles of clothing in a folded condition. The hand tool has a gun shaped casing, a hollow needle, a needle assembly, a trigger, a locking switch, a safety button, and a hinged anvil. In the first operating mode the hand tool is best adapted to dispense plastic fasteners to maintain an article of clothing in a folded condition. In the second operating mode the hand tool is best adapted to dispense plastic fasteners to attach labels, price tags, or other items to an article of clothing.

8. The dual operating mode hand tool for dispensing plastic fasteners as defined in claim 6 , wherein the dynamic portion is biased by a coil spring.
9. The dual operating mode hand tool for dispensing plastic fasteners as defined of claim 6 , wherein the dynamic portion is biased by a resilient plastic tab.
10. The dual operating mode hand tool for dispensing plastic fasteners of claim 6 , wherein the static portion and the dynamic portion each have a ramp for guiding fabric into a fabric slot.
11. The dual operating mode hand tool for dispensing plastic fasteners as defined in claim 5 , wherein the needle guard has a needle access door.
12. The dual operating mode hand tool for dispensing plastic fasteners of claim 1 , wherein at least one plastic fastener is provided for use with the hand tool.
13. A dual operating mode hand tool for dispensing plastic fasteners, comprising:
a casing, said casing being provided with a needle assembly opening;
a hollow needle;
a needle assembly, said needle assembly being slidably movable back and forth between a retracted position disposed substantially within said casing and an extended position disposed substantially out of said casing through an opening in said casing, a needle disposed on one end of said needle assembly; and
an anvil, said anvil having a front portion and a rear portion, said rear portion being secured to said casing, said front portion being rotatably attached to said rear portion, said front portion being capable of being rotated to extend in front of said opening in said needle assembly.
14. The dual operating mode hand tool for dispensing plastic fasteners as defined in claim 13 , wherein said hand tool further has a locking switch, said locking switch being capable of selectively locking said needle assembly in the extended position.
15. The dual operating mode hand tool for dispensing plastic fasteners as defined in claim 14 , wherein said hand tool further has a safety button, said safety button being capable of preventing said needle assembly from moving from the retracted position.
16. The dual operating mode hand tool for dispensing plastic fasteners as defined in claim 15 , wherein said casing has a barrel portion, a handle portion, and a channel portion.
