Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a connected nail, and more specifically, to a connected nail used in a nail gun that drives nails continuously using air pressure or the like.

[Conventional technology]

The connecting nails used in the nailing machine described above have a structure in which a large number of nails are held in parallel at regular intervals.

Conventional connecting nails are known to use holders made of thin sheets of synthetic resin to hold the nails at regular intervals.

A conventional connecting nail using the above-mentioned holder will be explained with reference to FIG.

The holder 1 has opposing walls 3 and 4 provided at regular intervals in the length direction of the substrate 2 on both sides of a strip-shaped substrate 2 made of a synthetic resin thin plate such as polypropylene or polyethylene. It has a structure in which depressions 5, 5 are opened.

The nail 6 has its body 7 inserted into the recesses 5, 5 of the opposing walls 3, 4.
By pushing and inserting it through the slightly narrowed opening on the distal end side, the distal end side and the head side of the body section 7 are held by the holder 1.

[The problem that the idea attempts to solve]

By the way, the above-mentioned conventional connecting nail has a body part 7 of the nail 6.
Since the recesses 5, 5 that hold the nail are open at the tip side, the holding force for the nail is extremely weak, and for this reason, if the nail is subjected to vibration when loaded into the nail gun, the nail 6 will fall off from the holder 1. There is a problem in that the nail driving operation becomes impossible.

In addition, in order to prevent the nail 6 from falling off from the holder 1 due to vibration, the entire circumference of the fitting part between the recess 5 of the holder 1 and the body 7 of the nail 6 is A connecting nail has been proposed in which the holder 1 and the nail 6 are fixed by being filled with a curable resin throughout the holder 1 and the nail 6 by the bonding force of the curable resin.

However, if the curable resin is applied to the recess and the entire circumferential surface of the body, the adhesion between the holder and the nail becomes too strong, and there is a problem in that the holder and nail cannot be separated during nailing.

Therefore, the problem of this invention is to solve the above problems by temporarily fixing the nail and the holder to prevent the nail from falling off, and also to ensure that the nail is removed from the holder when driving the nail. Our goal is to provide connecting nails.

[Means to solve the problem]

In order to solve the above-mentioned problems, this invention closes the opening of the recess provided in the opposite wall of the holder, which holds the leading end of the body of the nail on the opposite wall. A temporary fixing member for temporarily fixing the body portion is provided along the length direction of the holder.

[Effect]

A temporary fixing member that closes the opening of the recess is provided on the distal end side of the opposing wall that holds the tip of the body of the nail on the opposite wall of the holder. Nails do not fall off from the holder due to vibration.

In addition, because the temporary fixing is done along the length of the holder on the tip side of the body, the nail is fixed to the holder with appropriate temporary fixing strength, and the nail can be reliably separated from the holder when nailing. I can do it.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in the figure, the holder 1 is made of a thin synthetic resin plate, as described above, and has opposing walls 3 and 4 on both sides of a strip-shaped substrate 2, and depressions 5 and 5 that open at the ends of the opposing walls 3 and 4. The nail 6 is held in the holder 1 by inserting the body 7 into the recesses 5, 5.

In the holder 1, one opposing wall 3 that holds the distal end of the body 7 is provided with a temporary fixing member 11 that temporarily fastens the distal end of the opposing wall 3 and the body 7.

The temporary fastening member 11 is made of a soft, easily destructible material, such as a heat-meltable synthetic resin, and is continuously applied to the end of the opposing wall 3 in the lengthwise direction of the holder 1 so as to close the opening of the recess 5 .

In the illustrated case, the temporary fixing member 11 is continuously applied in a U-shaped cross section so as to cover the tip of the opposing wall 3, but it may be applied independently to each opposing wall 3, or in a linear cross-sectional shape, for example. You can do it like this.

The connecting nail of this invention has the above structure,
The nails 6 attached to the holder 1 are temporarily fixed by a temporary fixing member 11 attached to the tip side of one of the opposing walls 3, and the nails 6 are removed from the holder 1 by the vibration when loading the nailer. There is no chance of the nails falling off, and continuous nailing is possible.

During nail driving, the temporary fixing member 11 peels off from the opposing wall 3 and the body 7 due to the impact applied to the nail 6, and is ejected from the nose of the nailer. It will not cause any trouble.

By the way, when the head side of the body part 7 and the other opposing wall 4 are temporarily fastened with the temporary fastening member 11, the temporary fastening member will adhere to the back side of the head of the nail 6, and even if the nail is driven in, the temporary fastening member will not peel off. This is undesirable because it may cause the nail to be driven in together with the nail, or the detached portion may remain inside the nail gun, clogging the nose portion and making it impossible to drive a nail.

〔effect〕

As described above, according to this invention, the body of the nail is inserted into the recess provided on the opposite wall of the holder, the nail is held by the holder, and the tip side of the body is held, while the body is placed opposite the opposite wall. Since the nails are temporarily fixed using a temporary fixing member provided on the tip side of the wall, there is no possibility that the nails will fall out of the holder due to the vibration of the nail gun, and continuous nailing becomes possible.

In addition, since the temporary fixing is done on the tip side of the body, the temporary fixing material that comes off during nailing can be reliably discharged from the nose of the nailer, preventing the temporary fixing material from interfering with nail driving. Never.

Furthermore, since the temporary fixing member is provided along the length of the holder at the tip of the opposing wall, the application of the temporary fixing member to the holder can be performed continuously along the length of the holder, making the coating work more efficient. In addition to being able to temporarily fasten the opposing wall and the body with appropriate strength, the nail can be removed from the opposing wall without any problem during nailing, and the temporary fastening portion does not cause any inconvenience during nailing. There is no.
