Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape for connecting nails, and more specifically, it holds a large number of nails arranged at regular intervals so that the nails can be continuously driven using a nailing machine utilizing air pressure or the like. Regarding tape.

[0002]

2. Description of the Related Art A connecting nail used in a conventional nail driver is shown in FIG.
As shown in (A) and (B), a long tape 1 is used to hold a large number of nails 2 in parallel at regular intervals.

A conventional tape uses a synthetic resin thin plate,
Nail-holding wings 4 and 5 that are bent upside down on the strip-shaped side wall 3 so as to face each other.
Is formed in a U-shaped cross section, and the upper nail holding blade 4 and the lower nail holding blade 5 are opposed to each other and open at the side edges of the respective holding blades. 6,
6'is provided at a constant interval in the length direction.

The nail 2 is inserted by pushing the head side of the body portion 7 into the notch 6 of the upper nail holding wing 4 and the tip side into the notch 6'of the lower nail holding wing 5 from a slightly narrowed opening. Immediately after insertion, it is held by the contact friction between the opening and the peripheral wall of the notch which is restored to the original state by the elasticity of the synthetic resin.

[0005]

By the way, the conventional tape is formed by bending a thin strip of synthetic resin, and cuts 6 and 6'having slightly narrow openings in the upper and lower nail holding wings 4 and 5, respectively. Is provided to support the body portion 7 of the nail 2, and when inserting the nail, the body portion of the nail is inserted by expanding the narrowed opening.

Therefore, as shown in FIG. 7, when the body portion 7 of the nail 2 is considerably thicker than the cuts 6 and 6 ', the nail 2 cannot be inserted or can be inserted with a large pressing force. However, there is a problem that the opening which is expanded and deformed beyond the elastic limit cannot be restored in the insertion process and the holding force cannot be obtained.

SUMMARY OF THE INVENTION An object of the present invention is to provide a tape for connecting nails, which improves the expansion elasticity of the nail holding blades and provides a reliable holding force for the nails even in the forcible insertion process.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a nail-holding wing having a notch, which is formed by bending the side wall up and down so as to face each other. In addition, a structure in which a thin and thick portion is provided so as to reach the cut is adopted.

In the present invention, the thin-walled thick portion is formed by a groove formed on at least one surface side of the nail-holding wing, or an independent hole or kerf is provided between the notch and the side wall of the nail-holding wing to form the notch. It is also possible to provide a thin wall thick portion between the holes or kerfs.

[0010]

When the nail having a considerably thick body is inserted, the opening is first widened. At this time, the notch and the thin-walled thick portion that is continuous with the notch extend due to its elasticity. Due to the flexible stretchability obtained by the thin wall portion, when the thin wall portion extends slightly within the elastic limit range, the opening located on the terminal side of the deformation operation opens further, and the elastic limit is set in the opening portion. Nail insertion is performed without excessive deformation. Immediately after the nail body is inserted, the opening restores to the original position by the elastic restoring operation of the thin-walled thick portion and holds the nail body, so that sufficient nail holding force is obtained.
