Description

[Detailed Description of the Invention] [Industrial field of application] This invention proposes a large number of nails that can be continuously driven using a nailing tape, more specifically, a nailing machine utilizing air pressure or the like. The present invention relates to a tape that holds nails arranged side by side at regular intervals.

[Prior Art] The connecting nail used in the above-mentioned nailing machine has a structure in which a large number of nails 7 are held in parallel with a long tape 1 as shown in FIG.

As shown in FIG. 1, the conventional tape 1 is made of a synthetic resin thin plate, and the upper wall 3 and the lower wall 4 are bent to face each other above and below the strip-shaped side wall 2 to form a U-shaped cross section. And notches 5 and 6 for supporting the body portion 8 of the nail 7 at opposite positions of the lower wall 4 and the upper wall 3
And a structure provided at regular intervals in the length direction so that the side wall of the lower wall 4 opens.

The nail 7 is inserted into the notch 5 of the upper wall 3 by inserting the nail 7 into the notch 5 of the upper wall 3 and the notch 6 of the lower wall 4 by inserting the nail 7 from the slightly narrowed opening. Will be retained.

[Problems to be solved by the device]

By the way, since the conventional tape 1 is formed by bending a synthetic resin band-shaped thin plate into a U-shaped cross section, the upper wall 3 and the lower wall 4 are in a state in which they can be freely expanded, and during the transportation and work of the connecting nails. When external pressure is applied to the side wall 2 side of the nail 7 held by the tape 1, the upper wall 3 and the lower wall 4 are pushed open.

As described above, when the external pressure is applied to the nail 7, since the head 9 is in contact with the upper wall 3, the escape of the upper wall 3 in the expanding direction is prevented, and the body 8 by the upper wall 3 is prevented. Is maintained.

On the other hand, since the lower wall 4 holds the body portion only by the thickness of the thin plate, the amount of holding the body portion is small, so that the lower wall 4 is free to escape in the expanding direction, and the lower wall 4 is pressed by the external pressure applied to the nail 7. Slips and tilts toward the tip side of the body portion 8, the cut 6 separates from the body portion 8 and the tip side of the body portion 8 falls off,
There is a problem that nailing by a nailer becomes impossible.

Further, as a means for preventing the body part from falling off from the lower wall 4, a method of bonding the lower wall 4 and the body part 8 with an adhesive after inserting the nail 7 is conceivable, but it is troublesome to apply the adhesive. It is not economical because it takes time and the coating cost is high.

Therefore, an object of the present invention is to provide a tape for connecting nails capable of reliably preventing falling of nails without causing tilting due to slip of the lower wall even when external pressure is applied to the nails, in order to solve the above problems. To do.

[Means for Solving the Problems]

In order to solve the above problems, the present invention provides an upper wall and a lower wall, which project upward and downward on the same plane side of a side wall, in an opposed manner.
A cutback for holding the torso head side of the nail of the upper wall is provided so as to open at the side edge of the upper wall, and the folded wall facing the side edge of the lower wall by bending to the lower surface side of the lower wall. In this configuration, the lower wall and the folded wall are provided with notches for holding the body of the nail so that the folded edges of the both communicate with each other.

[Action]

The nail inserted into the tape is held by the notch of the upper wall on the head side of the body and by the notch of the lower wall and the folded wall on the tip side of the body.

Since the folding wall is located on the lower surface side of the lower part and holds the body part, the holding of the tip end side with respect to the body part becomes two places at the top and bottom to increase the holding force, and external force is applied to the side wall side to the nail. In addition, the lower wall and the folded wall can maintain the body holding state, and the nails can be reliably prevented from falling off.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2 of the accompanying drawings.

As shown in the figure, the tape 11 is made of a synthetic resin thin plate, and the upper wall 13 and the lower wall 14 of the strip-shaped side wall 12 are bent toward the same plane so as to face each other, and the lower wall 14 of the lower wall 14 is bent. The side wall has a cross-sectional shape in which folding walls 15 that are bent toward the lower surface of the lower wall 14 and are opposed to each other are connected.

The upper wall 13 has a body portion 8 of the nail 7 at regular intervals in the length direction.
A notch 16 for holding the head 9 side is provided so as to open at a side edge of the upper wall 13, and a notch 17 extending from the side edge to the side wall 12 is provided at a position between the notches 16.

The lower wall 14 and the folded wall 15 are provided with notches 18 and 19 for holding the tip side position of the body portion 8 of the nail 7 at a position facing the notches 16 of the upper wall 13 at regular intervals in the longitudinal direction. The lower wall 14 and the folded wall 15 are provided so as to communicate with each other at the folding edge so as to communicate with each other, and further, a notch 20 extending from the folded edge toward the side wall 12 is provided at a position between the notches 18 and 19 so as to communicate with each other.

Notch wall 1 provided in upper wall 13, lower wall 14 and folded wall 15
Reference numerals 6, 18, and 19 denote examples formed by combining a circular hole in which the body portion 8 is elastically fitted and an introduction notch which is continuous from the circular hole and expands outward, while being opposed to each other in the vertical direction. . The cuts 16, 18, and 19 may be arranged so as to hold the nail 7 in an inclined shape.

The tape of the present invention has the above-described structure, and as shown in FIGS. 1 and 2, the head 9 side of the nail 8 is covered with the upper wall 13 of the body 8.
The nail 7 is inserted into the notches 16 and the notches 18 and 19 of the lower wall 14 and the folded wall 15 to hold the nails 7 with the tape 11 at a constant interval to form connecting nails.

When the nail 7 is held by the tape 11 and an external pressure acts on the nail 7 toward the side wall 12, the upper wall 13 and the lower wall 14 that receive the external pressure try to expand.

At this time, the upper wall 13 is prevented from tilting in the expanding direction by contact with the head 9.

Further, on the lower wall 14 side, since the folded wall 15 connected to the lower wall 14 and the upper and lower two places of the body portion 8 are held by the lower wall 14, the holding force is excellent and the folded wall 15 is held. The lower wall 14 is prevented from slipping to the tip side of the body portion 8 by the force.

Therefore, the lower wall 14 and the folded wall 15 can maintain the holding state of the body portion 8, and the nail 7 does not drop off from the tape 11 and continuous nailing is possible.

〔effect〕

As described above, according to the present invention, the upper wall is provided with the notch for holding the torso head side of the nail, the side wall of the lower wall is formed with the folded wall that bends to the lower surface side, and the folded wall is folded with the lower wall. Since the wall has a notch that holds the tip of the body of the nail, the tip of the body of the nail can be held in two places, the lower wall and the folded wall, and the holding force on the tip of the body is greatly improved. Even if external pressure is applied to the shaft, it is possible to reliably prevent the dropout, and it is possible to drive nails continuously by a nailing machine.
