Material mechanical fastener
View Patent ↗A fastener suitable for temporarily or permanently connecting one object to another, for example a form to concrete. The fastener includes a nail having a guide wire bonded thereto, with the guide wire including a segment that extends outwardly past the tip of the nail, which facilitates insertion into a hole predrilled in the objects. The bond between the nail and wire is adapted to be broken in at least one area of connection when the fastener is driven into the predrilled hole.
1. A fastener for temporarily or permanently connecting objects to each other, the fastener comprising:
a nail comprising a shaft having a longitudinal axis, a head at a first end of the shaft that is wider than the shaft and a tip at a second end of the shaft; and,
a guide wire bonded to the nail in at least one location along the shaft, wherein the guide wire has a longitudinal length that extends a distance past the tip of the nail, wherein a bonding agent bonds the guide wire to the nail, wherein the bonding agent is one of more of solder, glue, adhesive and welding agent,
wherein the bond between the nail and the guide wire is adapted to be broken when the fastener is driven into a predrilled surface in the objects, whereby the nail and the guide wire independently remain whole.
2. The fastener according to claim 1 , wherein guide wire extends out past the tip a distance of at least 20% of the length of the nail, measured along the longitudinal axis.
3. The fastener according to claim 1 , wherein the guide wire has a hardness less than the Rockwell hardness of the nail as measured according to ASTM-E18-20.
4. The fastener according to claim 1 , wherein the guide wire is cylindrical, wherein the shaft is cylindrical, and wherein the guide wire has a diameter that is less than 48% of a diameter of the shaft.
5. The fastener according to claim 1 , wherein the head extends outwardly in a direction perpendicular to the longitudinal axis a distance greater than the guide wire, measured at one location where the guide wire is bonded to the shaft.
6. The fastener according to claim 1 , wherein the nail head is a duplex head.
7. The fastener according to claim 1 , wherein the guide wire runs parallel with the shaft along the length of the shaft.
8. The fastener according to claim 7 , wherein guide wire extends out past the tip a distance of at least 25% of the length of the nail, measured along the longitudinal axis.
9. The fastener according to claim 8 , wherein the guide wire is cylindrical, wherein the shaft is cylindrical, and wherein the guide wire has a diameter that is less than 37% of a diameter of the shaft.
10. A fastener for temporarily or permanently connecting objects to each other, the fastener comprising:
a nail comprising a shaft having a longitudinal axis, a head at a first end of the shaft that is wider than the shaft, and a tip at a second end of the shaft; and
a guide wire bonded to the nail in at least two locations along the shaft, wherein the guide wire has a longitudinal length that extends a distance past the tip of the nail,
wherein the bond between the guide wire and the nail is formed a) a tie and b) a connection of the guide wire to the nail without a bonding agent,
wherein the guide wire comprises a loop formed at one end of the guide wire, wherein the loop bonds the guide wire to the nail, forming the connection of the guide wire to the nail without a bonding agent,
wherein the loop is disposed adjacent the head at the first end of the shaft, and
wherein the tie is located closer to the second end of the shaft as compared to the loop.
11. The fastener according to claim 10 , wherein the tie is one or more of a clip, band and washer.
12. The fastener according to claim 11 , wherein the tie extends around the outside of both the guide wire and the nail to form the bond therebetween.
13. A method for temporarily or permanently fastening an object to concrete with the fastener according to claim 1 , comprising the steps of:
obtaining the fastener according to claim 1 ;
drilling a hole through the object and into the concrete, wherein the hole is sized to establish an interference fit with the fastener;
inserting the fastener into the hole with the guide wire entering the hole first;
driving the fastener into the hole and securing the object to the concrete as the fastener is driven into the hole.
14. The method according to claim 13 , wherein at least a portion of the guide wire is separated from the nail during the driving step.
15. The method according to claim 14 , further including the step of removing the fastener from the hole thereby leaving a portion of the guide wire within the hole.
16. The method according to claim 15 , wherein the object is a piece of wood, metal or plastic.
