Nail with a reinforcement section

Abstract

A nail includes a head and a shank which extends from an underside of the head and includes a reinforcement section a shank body. A tip portion is formed on a distal end of the shank body and the reinforcement section is connected between the head and the shank body. A diameter of the reinforcement section is larger than a diameter of the shank body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 3, the nail 3 of the present invention comprises a head 30 and a shank 31 which extends from an underside of the head 30. The shank 31 includes a reinforcement section 310 a shank body 311. A cone-shaped tip portion 32 is formed on a distal end of the shank body 310 and the reinforcement section 310 is connected between the head 30 and the shank body 311. A diameter of the reinforcement section 310 is larger than a diameter of the shank body 311, and a diameter of the reinforcement section 310 is smaller than a diameter of the head 30. The tip portion 310 can also be different shapes such as wedge-shaped tip portion or rhombic cone tip portion.

As shown in FIGS. 4 and 5, the nails 3 are sent into the nose of the pneumatic nailer one by one and the nail 3 aims the hole 40 in the metal board 4 which is located on a wood block 5. The nail 3 is pushed by the piston rod 6 when the user pulls the trigger of the nailer. As shown in FIG. 5, the nail 3 nails into the wood block 5 via the hole 40. It is noted that the reinforcement section 310 fills the hole 40 so that even if the metal board 4 shifts, the reinforcement section 310 is strong enough to bear the shear force. Besides, only a small gap is formed between the reinforcement section 310 and the inner periphery of the hole 40 so that the metal board 4 only shifts a little bit and the shear force is much less than the shear force applied to the conventional nail 1 as described in FIGS. 1 and 2.

While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.

Claims

1. A nail 3 comprising: a head 30 and a shank 31 which extends from an underside of the head 30, the shank 31 including a reinforcement section 310 a shank body 311, a tip portion 32 formed on a distal end of the shank body 310 and the reinforcement section 310 connected between the head 30 and the shank body 311, a diameter of the reinforcement section 310 being larger than a diameter of the shank body 311.

2. The nail as claimed in claim 1, wherein the tip portion 32 is a cone-shaped portion 32.

3. The nail as claimed in claim 1, wherein a diameter of the reinforcement section 310 is smaller than a diameter of the head 30.
