Abstract

PURPOSE:To provide a nail puller having extremely high commercial value which can be a product usable also as a driver without increasing the cost by an easy means in a large-sized nail puller which should manufactured by bending the top end part of a steel bar on one side. CONSTITUTION:In a nail puller in which the top end part of a steel bar 1 is bent toward one side, and a nail puller part 3 is formed on the top end part of the bent part 2, a swollen part 4 is formed in the protruded state on or near the bent part 2 formed on the bar 1 top end side, and a nail driving surface 5 is formed on the top end side opposite to the nail puller part 3 of the swollen part 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to nail pulling, which is also called a burl.

[0002]

2. Description of the Related Art Conventional nail pullers are generally formed by forging. Therefore, for example, as shown in FIG. 4, it is possible to form the nail punching portion 10 on one side of the tip and to form the metal punch 11 on the side opposite to the nail pulling portion 10 because of the integral molding by forging. However, for nailing up to about 30 cm in length, forging can be performed as described above, but for nailing larger than that, for example, for lengthing 40 cm or more, forging is difficult with current general processing machines. Therefore, for such large-scale nail pulling, a steel rod-shaped body is once drawn and formed, the tip of this straight rod-shaped body is bent, and the bent tip is cut or grooved. I had no choice but to form a nailed portion.

[0003] Therefore, in the large-scale nail cutting that involves such a bending process, there is no one having a hammer part which can be used as a conventional hammer.

In view of the above situation, the present invention provides a very large nail puller that can be used as a hammer even though it is a large nail puller that does not require forging.

[0005]

The gist of the present invention will be described with reference to the accompanying drawings.

In the nail pulling in which the tip end of the steel rod 1 is bent toward one side and the nail pulling portion 3 is formed at the tip of the bent portion 2, the tip formed on the tip end side of the rod 1 A build-up portion 4 is additionally formed in a bent state at or near the bent portion 2, and a nailing surface 5 is formed on the tip end surface of the build-up portion 4 opposite to the nail pull-out portion 3 side. The present invention relates to nail pulling.

[0007]

When used as a hammer, a nail or the like is hit with the nail pulling surface 5.

[0008]

EXAMPLE In the present example, the present invention is applied to a large nail puller having a length of about 45 cm.

[0009] When such a large nail is removed, it is extremely difficult to integrally form it by forging, and the cost is very high because there is no forging device that enables it.

Therefore, as in the conventional method, a linear bar 1 is formed by drawing a steel material, the tip of the bar 1 is bent toward one side, and the tip of the bent part 2 is cut. Processing and grooving processing to form the nail pulling portion 3 having a V-shaped groove,
The burl portion 6 is formed at the base end of the rod 1.

A built-up portion 4 is attached to the bent portion 2 or the vicinity of the bent portion 2 formed on the tip end side of the rod 1 in a bulging state, and the built-up portion 4 and the nail pulling portion 3 side. Has a nailing surface 5 on the opposite end surface.

FIG. 1 shows a first embodiment, in which a fitting member 7 made of steel of the same quality is fitted in a predetermined range from the bent portion 2 toward the base end side and fixed by welding. A bulging portion 4 protruding in a bulging state is formed on the opposite side of the bent portion 2 from the nail pulling portion 3, and a nailing surface 5 with an anti-slip line is formed on the outer surface of the bulging portion 4. There is.

Further, as a finish, the entire bar 1 including the fitted member 7 is painted so that the boundary with the fitted member 7 cannot be seen visually.

FIG. 2 shows a second embodiment, in which a block-shaped build-up portion 4 is welded and fixed to the outer surface of the bent portion 2 and a nail-pulling surface 5 is formed on the outer surface of the build-up portion 4. ing. Similarly, it has been painted.

FIG. 3 shows a third embodiment, in which a pair of connecting cylinders 8 each having a cylindrical built-up portion 4 formed by butting are joined to a bar 1 near the bending portion 2. The material 1 is bonded so as to be held by both sides and fixed by welding, and the coupling cylinder 8 is also fixed to the bar material 1 in an intersecting state to form the build-up portion 4, and the build-up portion 4 is formed. A nailing surface 5 is formed on the outer surface of the portion 4 opposite to the nail pulling portion 3.

In this embodiment as well, a non-slip strip is similarly formed on the paint finish or nailing surface 5.

[0017]

INDUSTRIAL APPLICABILITY The present invention can be used as a hammer with a simple means without cost in a large-scale nail pulling process in which the tip of a steel bar must be bent toward one side to be manufactured. It can be a product, and it has a very high commercial value.
