Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a method for driving wooden nail materials.

(Conventional technology) For the drawers of high-quality furniture, wooden nails are used in the old-fashioned way to join wooden boards together, but this work is done exclusively by using wooden boards such as cypress and cypress, which are made by hand by craftsmen. The nail is hammered into a small hole that has been previously drilled with a drill.

In contrast to the existing manual hammering method, there has recently been a proposal to use a nail gun that is the power source for an air compressor.

(Problems to be Solved by the Invention) The nailing machine 1 according to the above proposal is as shown in FIG. 1, and an air plug 1b at the rear end of the main body 1a is connected to a hose 2 from an air compressor (not shown). At the same time, by holding the main body 1a in your hand and pulling up the lever 1a with your fingertip (usually your index finger), you can sequentially feed out the plastic nails stored in the magazine 3 and press the pusher inside the main body 1a. It is moved so that the nail can be driven.

At this time, the plastic nails 4 are articulated nails as shown in FIG. 2, and the individual nails 4', 4'', 4''... are composed of a cylindrical body 4a and a head body 4b whose upper part is flat. In addition, adjacent nails are connected with joints 4c as appropriate. The piston of the nail gun is pressed to a lower position within the magazine 3 by the elastic force of the spring, and when the lever 1c is actuated, the piston moves each nail 4', 4'', 4... to the cylindrical body 4a. and a head body 4b whose upper part is flat-shaped, and adjacent nails are connected with joints 4c as appropriate.Then, within the magazine 3, the repulsive force of the spring moves the nailer's piston to the lower position. When the lever 1c is actuated, the piston moves the individual nails 4',
4'', 4... are ejected from the magazine 3 by hitting the head body 4b.

By the way, although driving plastic nails using the above-mentioned nailing machine improves work efficiency compared to manual driving, it still inevitably results in a negative image when used on high-end furniture.

(Means for Solving the Problems) The present invention aims to solve the above problems, and its characteristics include the production of specially shaped wooden nails in place of plastic nails, and the use of specially shaped wooden nails in place of plastic nails. A magazine with a special shape is created to suit the needs of the nailer, and by using these magazines, it is possible to efficiently drive nails into high-quality furniture by simply operating a lever on the nailer.

Specific features of the invention are illustrated by the following examples.

(Example) FIG. 3 shows a wooden nail 5 used in the present invention, in which A is a front view and B is a side view cut along the line X-X.

Here, the wooden nail 5 is formed into a thin rectangular plate whose straight grain is approximately perpendicular from the upper side to the lower side in the length direction, and the upper side is slightly thicker than the lower side. By forming the nail thickly, the cross section becomes wedge-shaped, and by leaving a certain dimension on the upper side, slits 6 are bored at certain width intervals, so that the connecting nail connects the head m and the contact part n. It has a continuous comb-like structure.

The dimensions of each part of the wooden nail 5 can be arbitrarily designed depending on the capacity and dimensions of the nailing machine 1 and magazine used, but as an example, the working air pressure is 5 kg/cm ²
(regulator gauge pressure) horizontal dimension l =
120mm, vertical dimension l' = 20mm, upper side wall thickness S = 3mm,
The lower side wall thickness S' = 2 mm, the head length g = 2 mm, the slit width e = 1 mm, and the individual nail width f = 2 mm.

FIG. 4 is a usage state diagram. In the use of the present invention, the magazine 7 has a sliding groove 8 formed to have a wedge-like cross section similar to the shape of the wooden nail in order to store the wooden nail 5 having the above-mentioned structure, and the wooden nail 5 can be driven by a metal hammer. The head 10a of the pusher 10, which is resiliently repulsed by the spring 9, is pressed horizontally to the lower part of the piston 1 of the wooden nail 5. This is done by pressing against the back. At the tip of the magazine 7, there is a driver guide 1 which also serves as a groove for receiving the repulsive force of the pusher 10 and for driving the wooden nail 5 downward by the operation of the piston.
1 are provided in a pair (11c, 11b) facing each other, and at least one of these driver guides (11a in the illustrated example) is provided with a notch 12 into which the joint m between the wooden nail heads n can be inserted. When driving a wooden nail, the seam m between the adjacent wooden nail heads is the above-mentioned notch 1.
It is designed to be carried out in a state where it is fitted in This is because the straight grain of the board is in the same direction as the piston's operating direction, so the joint m part will easily break with the head n of the wooden nail as the piston works, and the broken part Since the side surface of the notch 12 of the contact m portion is in an open state, the liquid is naturally discharged through the notch 12 to the open side.

(Effects of the Invention) The present invention creates wooden nails with a special shape as described above, and also creates a separate magazine for storing wooden nails suitable for the wooden nails, and by using these, the magazine can be loaded by simply operating a lever using a nail gun. It is possible to drive wooden nails continuously and efficiently.

According to the present invention, since the nails are driven using wooden nails, there is no sense of incongruity with the board material that has been driven.
Since it is made by hand by craftsmen, it does not tarnish the image of high-quality furniture.

Claims (1)

[Scope of Claims] 1. A thin plate made of a board material such as a roof or Japanese cypress, which has a wedge-shaped cross section in which the upper side in the longitudinal direction is thicker than the lower side, and the straight grain runs from the upper side to the lower side. None, by leaving a certain dimension on the upper side of the thin plate as a contact area with the head body, a large number of slits are bored at constant width intervals in the length direction to create a wooden nail with a comb-like shape as a whole. A method for driving a wooden nail, comprising: storing the wooden nail in a magazine of a nailing machine using an air compressor, and driving the wooden nail into wooden furniture. 2. Remove the part corresponding to the head of the wooden nail in the driver guide, which receives the wooden nail pressed against the magazine end via a spring and guides the driving of the wooden nail by the action of the piston of the nailer. 2. A magazine for a nailing machine according to claim 1, wherein the magazine is formed in a notch that is open toward the front, into which a joint portion between adjacent wooden nail heads is inserted when driving a wooden nail.
