Description

[Detailed description of the invention] "Industrial application field" This invention is equipped with a nail storage chute and a feeding function that can store a large number of nails and allow the stored nails to be reliably and easily fed out with a single touch operation. This invention relates to a nail holder.

``Conventional technology'' Conventionally, when manually driving nails continuously, there are two methods: a mechanical method using a nail driving tool, and a method in which the nails are picked up and held one by one by hand, and then driven in with a hammer, etc. This method can be roughly divided into the hand-held method by striking the tool.

At that time, when holding the nail,
In the mechanical method, a nail storage casing capable of storing a large number of nails is equipped, the nails are aligned in this nail storage casing, and the first nail is fed out to a nail striking position where it is driven. At the same time, once the nail has been driven, the next nail is fed out.

On the other hand, with the handheld method, you take out each nail one by one and hold the nail while driving. By repeating this operation, the nails are driven in one after another. As a result, the work is complicated, and work efficiency is extremely low, especially when working in cold seasons or nailing work in narrow spaces. Also, it is not possible to do nailing work in an orderly manner, which causes some problems.

Therefore, regarding these improvements, especially improvements in the hand-held method, there are the following technical documents.

First, there is a nail driving device disclosed in Japanese Utility Model Application Publication No. 57-63677, the gist of which is that a vertical groove for biting the nail is provided vertically on the nail gripping stand, and this vertical groove grips the nail in a vertical position. This vertical groove is opened and closed using a handle.

There is also a nail holder for nail driving disclosed in Japanese Utility Model Application Publication No. 63-44784, which consists of an elastic holding plate and a handle, and the elastic holding plate has a slit that reaches its outer peripheral end surface. This is a configuration in which a holding hole is provided.

``Problems to be Solved by the Invention'' The mechanical method described in detail above has the advantage that a large number of nails can certainly be stored in the nail storage casing, and the nails can be automatically and continuously supplied.

However, this nail accommodating casing is integrated into the device, and cannot be used alone, and other usage methods are completely unthinkable. As described above, the usage of nail storage casings is limited.

Furthermore, although the above-mentioned technical literature has the advantage of gripping the nail and maintaining this grip until the time of driving, it has the advantage of being able to grip the nail and maintain this grip until the time of driving. It is done manually one by one, which is very complicated, and it is not possible to do it automatically and continuously.
The nail cannot be fed or drawn out, which is considered to be a major problem.

``Means for Solving the Problems'' In view of the above, the present invention has developed a chute installed in the main body case that can store a large number of nails, in order to create a structure that allows nails to be automatically and continuously fed out with one touch and reliably. a rotary cylinder provided on the delivery side of the chute and provided with a nail storage groove capable of storing several nails and rotated via a pivot; an operation plate for controlling the rotation of the rotary cylinder at a constant pitch; After the operation plate rotates a certain pitch, the rotation distance of this constant pitch is maintained (so-called retraction of the operation plate,
Prevents the rotating cylinder from returning after rotating at a certain pitch. )
A regulation plate, a supply cylinder having a feeding hole in which the foremost nail located in a nail storage groove provided on the feeding side of the rotary cylinder is moved and stored through the magnetic force of a magnet; It consists of an extruded rod that is slidably installed in the feeding hole.

Also, the rotation of the rotating tube and rotation regulation (rotation stop)
In order to ensure that the nails The structure is such that the rotary cylinder is conveyed sequentially through this rotation, and the rotation of the rotary cylinder, which has advanced by a certain pitch of rotation, in the return direction is restricted through the control of a restriction plate.

Further, in order to reliably feed the first nail located in the nail storage groove on the feeding side of the rotary tube to the feeding hole of the feeding tube, a magnet is provided on the feeding tube.

"Operation" The operation of the present invention will be explained below. When a large number of nails are sequentially inserted through the opening made in the case lid of the main case, a large number of nails are filled into the nail storage groove of the chute of the main case. , and the foremost nail is located in the supply side opening of the bottomed cylinder and the nail storage groove of the rotating cylinder.

The so-called first nail is in the extended position.

In this state, the claw piece of the operation plate is engaged in the nail storage groove in front of the nail storage groove in which the first nail is stored, and the claw piece of the regulation plate is engaged in the nail storage groove in front of the nail storage groove further in front of the nail storage groove. It is stuck in the groove.

Therefore, if you hold the main body case in your left hand (or even your right hand),
Yes. ), place one of your fingertips on the operation plate, and slide your fingertips forward. Through the forward movement of the claws on the operation plate, the rotary cylinder is pressed by the claws on the regulation plate. Try to win the game,
As it rotates in the forward direction as shown by the arrow in Figure 2, the regulating plate is disengaged from the nail storage groove, and its claws are repelled so as to follow the circumferential surface of the rotating tube, and the circumference of the moving rotating tube. It remains in the pressed position until it reaches the next nail storage groove (the nail storage groove located before the nail storage groove filled with the first nail). At the same time, the empty nail storage groove becomes in a positional relationship that matches the nail storage groove portion of the chute. The forward rotation of the rotary cylinder at a constant pitch ends when the operating plate stops sliding.

When this forward rotation at a certain pitch stops, the operation plate returns to its original position via a tensioning means such as a spring, and the claws of the regulation plate move into the nail storage groove of the rotating tube (the first nail mentioned above is filled in). (The nail storage groove is located in front of the nail storage groove located in front of the nail storage groove.) and prevents the rotary cylinder from rotating in the return direction (so-called reverse rotation).

In this example, by repeating the above operation again, the nail storage groove in which the first nail is stored will be in a position that matches the opening on the feeding side of the bottomed cylinder, and the supply cylinder will It communicates with the nail feeding hole through a guide hole provided in the hole.

The first nail stored in the so-called nail storage groove of the rotary cylinder is in the extended position.

Therefore, in principle, the first nail can freely move from the opening on the feeding side of the bottomed cylinder to the guide hole of the supply cylinder and then to the feeding hole of the supply cylinder. As a result, the first nail at the feeding position is forcibly attracted along the route and guided into the feeding hole through the magnetic force of the magnet.

In this way, the first nail guided into the feeding hole is in a state where it can be easily pushed out in the vertical direction by the pushing rod sliding within the feeding hole.

Therefore, this supply tube is placed at the nail driving position, and the head of the extrusion rod is lightly tapped with a hammer. Then, the extrusion rod moves downward, and along with this downward movement, the nail reaches the outside through the feeding hole of the supply cylinder and is driven into the surface to be nailed (such as a board surface).

Therefore, the nail is set upright on the surface to be driven, so move this device away from this area, drive the upright nail, and then move the device to the next nailing location and repeat the process described above. The next nail is driven in the same way as in the previous nail.

"Embodiment" An embodiment of the present invention will be specifically described below with reference to the drawings.
