Having Penetrating Portion Retractable Or Of Changeable Length Patents (Class 24/710.4)
  • Safety tack
    Patent number: 9162517
    Abstract: A safety tack has a pin that is extended from a head of the tack in one state and retracted into the head in another state. The pin retracts and extends into and from the head by using a turning mechanism similar to the mechanism that allows a bolt to turn into and out of a complementary component (e.g. a nut). By having the retracted state, the tack can be handled without injury; and by having the extended configuration, the tack can be used to tack one object to another.
