Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for driving wooden nails that are used for fixing wooden members together.

[Conventional technology]

Traditionally, when making wooden furniture such as chests of drawers and desks, where soft wood is used, if you use regular metal nails, the nails may fall out over a long period of time, so wooden nails or bone nails are used. are using.

Conventional wooden nails and bone nails are made by cutting wood into a nail shape and heating it to harden it until it becomes charred.

[Problem that the invention attempts to solve]

However, conventional wooden nails have a wedge shape or a round bar shape with a pointed tip, and because they are made of a piece of wood strong enough to withstand driving, one surface is relatively smooth, and there is often a problem that they fall out after driving. ,! Ta. Another problem with gold is that it is difficult to implant the metal if the surface is not smooth to prevent it from coming off.

[Means for solving problems]

The present invention is intended to solve all of the above-mentioned conventional problems, and the object is to provide a complete method for driving a wooden nail that is easy to drive and does not easily fall off after driving.

In other words, in the present invention, a hole for discharging adhesive is opened in the wooden nail driving machine near the hole through which the wooden nail to be driven is injected, and the adhesive is completely applied to the wooden nail when driving the wooden nail. Did you do that? Features.

The wooden nail driving machine used in the present invention can be used by completely improving the machine that has been conventionally used for this type of application. For example, it may be a method using a compressed blank sheet, or a manual method such as a large stapler.

As the wooden nails, conventionally used wooden nails can be used as is, such as model nails or round sticks with sharp tips.

As an adhesive, it is applied to wooden nails during driving, so
It is preferable to use a liquid adhesive at the time of application, and for example, vinyl resin adhesives such as vinyl chloride-vinyl acetate copolymer, water-soluble urea resins, etc. can also be used. In addition, the hot melt adhesive may be completely melted and applied by providing a heating device to the driving machine.

[For production]

According to the method of the present invention, an adhesive is applied to the surface of the wooden nail during driving, so depending on the adhesive, there is no lubricant effect at all, making driving easier.

After driving, it acts as an adhesive and completely prevents the wooden nail from coming out. Therefore, conventionally, a hole is sometimes drilled at the place where the wooden nail is driven, but even if this hole is a little too large considering the thickness of the wooden nail, there is no problem and both parts that should be joined with the wooden nail can be completely fixed. .

〔Example〕

EXAMPLES The present invention will be explained below with reference to examples, but the present invention is not limited to these examples.

FIG. 1 is a perspective view showing an example of a wooden nail driving machine, in which 1 is the main body of the wooden nail driving machine, 2 is an adhesive discharge pipe, 3 is a wooden nail, 4 is a trigger, and 5 is a grip metal.

In FIG. 1, the wooden nail 3 is inserted from the rear (right side in the figure) of the main body 1 and ejected forward (to the left side in the figure). In this case, the adhesive discharged from the tip of the adhesive discharge tube 2 is attached to the wooden nail 3 and driven into the target object.

FIG. 2 is a sectional view of the driving machine main body 11 to show another embodiment of the present invention, in which an adhesive holding chamber 12 provided in the main body 11 is filled with an adhesive 21, and a wooden nail is 3 is applied by the adhesive 21 discharged from the discharge port 22 provided just before the adhesive is injected. In the case of the driving machine shown in FIG. 2, it is preferable to use an adhesive at room temperature.

Fig. 3 shows an example of a nine driving machine equipped with a heater 6 in the main body 11.
1, and is melted by the heater 6 in the main body 11 and applied.

FIG. 4 is a sectional view showing a state in which the wooden nail 3 is driven to join the timbers 7 and 8, and shows a state in which the adhesive 21 is present around the wooden nail 3.

〔Effect of the invention〕

In the present invention, since an adhesive is applied to the outer periphery of the wooden nail during the above-described driving, conventional wooden nails can be used without using any special wooden nails. There is no need to apply adhesive to the wooden nail in advance, so you can choose from a wide range of adhesives, and some adhesives can act as a lubricant during driving, improving driving efficiency. It also has the effect of being able to Of course, since the wood is coated with adhesive, the wooden nails will not come out easily.

[Brief explanation of drawings]

Figure 1 is a perspective view showing an example of a driving machine, Figures 2 and 3 are cross-sectional views of the main parts of the driving machine to explain other examples of the driving machine, and Figure 4 shows how to drive a wooden nail.
