Abstract

(57) [Summary] [PROBLEMS] To easily remove a board or the like even when a nail head cannot be pinched by a nail pulling part. SOLUTION: A handle portion 1, a bent portion 3 formed at the tip of the handle portion, and a nail removal portion 4 formed with the bent portion having a forked tip.
A pillar-shaped pillow portion 5 which is orthogonal to the long axis of the handle portion and protrudes on both sides of the nail pulling portion and serves as a fulcrum of the handle portion is fixed to the outside of the bent portion. For example, when the board 13 is nailed to the rafter 11 with the nail 12 and the head of the nail sinks and cannot be pinched by the nailed portion, the pillow is hit against the rafter to support the crowbar,
When the handle is rotated with the nail pulling portion applied to the back surface of the board, the board can be easily peeled from the rafter.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to the improvement of crowbars used for dismantling buildings and wooden boxes.

[0002]

[Prior art]

 A conventional crowbar has a handle portion, an insertion portion formed by gradually reducing the rear end of the handle portion, a bent portion formed by making the tip of the handle portion U-shaped or hook-shaped, and a tip portion of the bent portion. And a nail puller formed in a forked shape. Then, for example, when peeling the board struck against the rafter, if the insertion portion is inserted between the rafter and the board and the handle is rotated, the board can be peeled from the rafter. When pulling out the nail, the nail can be easily pulled out by sandwiching the head of the nail between the nail pulling parts and applying the principle of leverage and rotating the handle with the bent part as a fulcrum. However, there is also a case in which the insertion portion is not formed.

[0003]

[Problems to be solved by the invention]

 However, when the nail had been driven into the board and the head had sunk into the board, the nail could not be easily pulled out unless the nail head was pinched by the nail puller. The problem to be solved by the present invention is to make it easy to peel off the board even when the nail head is sinking.

[0004]

[Means for Solving the Problems]

 This invention consists of a handle, a bent portion formed at the tip of the handle, and a nailed portion formed by making the tip of the bent portion bifurcated, and the long axis of the handle is provided outside the bent portion. A pillar-shaped pillow portion, which is orthogonal to the bending portion and protrudes to both sides of the bent portion and serves as a pivot of the handle portion, is fixed.

[0005]

[Embodiment of the invention]

 Reference numeral 1 denotes a handle portion, and 2 denotes an insertion portion, which is formed by gradually thinning the rear end of the handle portion. Reference numeral 3 denotes a bent portion formed by making the tip of a handle portion into a U-shape, and 4 denotes a nail-pulling portion, which is formed by making the tip of this bent portion a forked shape. The handle portion 1, the insertion portion 2, the bent portion 3, and the nail removal portion 4 are integrally formed of steel.

Reference numeral 5 denotes a pillow portion according to the present invention, which is formed in a triangular prism shape, and is fixed to the outside of the bent portion 3, that is, on the side opposite to the opening side, by welding perpendicular to the long axis of the handle portion. , Protruding on both sides of the bend. The attachment position of the bent portion 3 of the pillow portion 5 is, as shown in the figure, at the bending end point of the bent portion, that is, near the end of bending at the nail pulling portion 4 side. When the handle 1 is turned in the direction of the arrow in FIG.

Although the pillow portion 5 can be formed in a columnar shape, the pillow portion 5 has a triangular shape so that it is less slippery and can be easily fixed to a bent portion. Further, it is preferable that the pillow portion is provided with irregularities so that the pillow portion is less likely to slip when the handle portion 1 is turned with force.

From the above configuration, as shown in the drawing, for example, when peeling the board 13 hit against the rafter 11 from the rafter, the pillow portion 5 is applied to the rafter to support the bar, and the nail puller 4 is connected to the rafter. Apply to the back. When the handle 1 is rotated in the direction of the arrow in FIG. 1, the crowbar 5 against the rafter stabilizes the crowbar, and the pillow serves as a fulcrum to easily peel off the board from the rafter. Can be. Also, when the nail head is floating from a board, rafter, pillar or the like and can be sandwiched by the nail puller 4, if the handle is rotated with the pillow as a fulcrum, the nail can be easily pulled by the principle of leverage. Can be pulled out.

Although the burl having the bent portion formed in the U shape has been described above, the same operation and effect as described above can be obtained even when the tip of the handle portion is formed in a hook shape, that is, bent at a right angle. Can be raised.

[0010]

[Effect of the invention]

 By providing a pillow, the burl can be stably supported by the pillow, and when the handle is rotated, the fixed board or rafter can be easily peeled off using the pillow as a fulcrum by the principle of leverage. be able to.
