Abstract

(57) [Abstract] [Purpose] To provide a nail pulling device capable of pulling straight out without bending the nail. A vertical nail pulling device 10 includes a hook 12 that is vertically movably supported by a frame 11 and is engaged with a head H of a nail N.
And a handle lever 13 which is supported by the frame 11 so as to be tiltable in the vertical direction and whose one end 27 is rotatably connected to the hook 12. When a worker pushes down the other end 30 of the handle lever 13 with the nail N hooked on the hook 12, one end 27 of the handle lever 13 tilts upward and pulls the hook 12 upward. Nail N is
Hook 12 guided by frame 11 and rising straightly
Because it is pulled out from board B by
It is pulled straight out.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a nail pulling device for pulling a nail vertically (that is, perpendicular to a driven surface, in other words, along the longitudinal direction of the nail).

[0002]

[Prior art]

 BACKGROUND ART Conventionally, when pulling out nails in a packaging box or a concrete frame at a construction site, a bar-shaped nail puller with an L-shaped tip is used.

[0003]

[Problems to be solved by the device]

 However, in such a burl-shaped nail puller, the nail is often pulled out while bending the nail with the bent portion as a fulcrum. For this reason, the nail that has been pulled out has a problem that it cannot be used again until it is hit with a hammer to straighten it.

[0004]

[Means for Solving the Problems]

 The present invention comprises a hook that is vertically movably supported on a frame and that engages with the head of a nail, and a handle lever that is vertically tiltably supported on the frame and has one end rotatably connected to the hook. The above-mentioned problems were solved by the vertical nail pulling device equipped with.

[0005]

[Action]

 When a worker pushes down the other end of the handle lever with the nail hooked on the hook, one end of the handle lever tilts upward and pulls the hook upward. The nail is pulled out of the board by the hook. At this time, the hook is pulled straight up within the frame, and the nail is pulled straight out without bending.

[0006]

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. A vertical nail pulling device (hereinafter referred to as “nail pulling device”) 10 includes a frame 11, a hook 12, and a handle lever 13. The frame 11 is a portion installed on the plate B, and has a shape in which two plates are spaced apart from each other and are integrated by the beam 23 and the hit portion 21. The hit part 21 is firmly formed on the lower part of the frame 11 so as to project.

The frame 11 is formed with elongated holes 22 and 22 which are elongated in the vertical direction. A pair of pins 24, 25 for guiding the hook 12 to move up and down are engaged with the elongated holes 22, 22. A handle lever 13 is supported on the frame 11 by a shaft 26 so as to be vertically movable.

A hook 12 is connected to one end 27 of the handle lever 13 by a pin 24 and an elongated hole 28. The long hole 28 is formed in the longitudinal direction of the handle lever 13. A tension spring 29 is provided between one end 27 of the handle lever 13 and the frame 11. A grip 31 is provided on the other end 30 of the handle lever 13.

The distance between the pin 24 and the shaft 26 is set shorter than the distance between the shaft 26 and the grip 31. This is to allow the nail N to come off with a slight force by the lever principle. The hook 12 has a pair of claws 32, 32 formed in a bifurcated shape so as to engage with the head H of the nail N.

Next, how to use the nail pulling device 10 will be described. First, the right end (right side in FIG. 1) of the frame 11 is separated from the plate B, the lower surface 41 of the hook 12 is brought into close contact with the plate B, and the entire end of the nail puller 10 is tilted in the counterclockwise direction. 1 is hit with a hammer to the left in FIG. 1, and the claws 32, 32 of the hook 12 are made to bite under the head H of the nail N. Next, the other end 30 of the handle lever 13 is pushed down in the direction of arrow C in FIG. Then, the nail N is pulled out to such an extent that the head H of the nail N that has been bitten into the plate B is separated from the plate B, the lower surface 42 of the frame 11 is brought into close contact with the plate B, and the nail N and the nail pulling device 10 are shown in FIG. It becomes the state of 1.

Subsequently, when the handle lever 13 is pushed down in the direction of arrow C, the handle lever 13 is rotated rightward in FIG. 1 about the shaft 26 to pull up the hook 12. The hook 12 is pulled straight by the guide of the pins 24 and 25 and the long hole 22. Therefore, the nail N is pulled out straight from the plate B. At this time, the nail N is pulled out with a slight force by the lever principle of the handle lever 13. That is, the shaft 26 serves as a fulcrum, the grip 31 serves as a force point, and the hook 12 serves as an action point.

In this way, the nail N is pulled straight out of the plate B with a slight force, and can be reused as it is. If a nail N1 having a special collar H1 with which the hook 12 of the nail removing device 10 is engaged is used for the nail, as shown in FIGS. Since it is easy to insert, the work of pulling out the nail N1 using the nail pulling device 10 of the present invention becomes easier.

[0013]

[Effect of device]

 According to the nail pulling device of the present invention, since the nail can be pulled straight, the pulled nail can be reused as it is.
