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.

[Conventional technology]

The connecting nail used in the above-mentioned nail driver is, as shown in FIG.
A long tape 1 holds a large number of nails 7 in parallel at regular intervals.

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. The holding portions 5 and 6 for supporting the body portion 8 of the nail 7 are provided at opposing positions of the lower wall 4 and the lower wall 4 at regular intervals in the length direction so as to open at the side edges of the upper wall 3 and the lower wall 4. It is structured.

The nail 7 is inserted by pushing the head portion 9 side of the body portion 8 into the holding portion 5 of the upper wall 3 and the tip end side into the holding portion 6 of the lower wall 4 from a slightly narrowed opening. Will be held at.

[Problems to be Solved by the Invention] 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 can be expanded freely. When the external pressure is applied to the side wall 2 side of the nail 7 held by the tape 1 during the transportation and the operation of the connecting nail, the upper wall 3 and the lower wall 4 are pushed open.

As described above, when the external pressure is applied to the side wall 2 side of the nail 7, the head 9 is in contact with the upper wall 3, so that the escape of the upper wall 3 in the expanding direction is prevented, and the upper wall 3 is prevented. The holding of the body portion 8 by 3 is maintained.

On the other hand, the lower wall 4 is free to escape in the expansion direction,
Due to the external pressure applied to the nail 7, the lower wall 4 slips and tilts toward the tip side of the body portion 8, the holding portion 6 separates from the body portion 8, and the tip side of the body portion 8 falls off the tape 1, There is a problem that nailing with a hammer is impossible.

Further, as a means for preventing the body portion 8 from falling off from the lower wall 4, it is conceivable to insert the nail 7 into the holding portion 6 and then bond the lower wall 4 and the body portion 8 with an adhesive. It is uneconomical because it takes time and labor to apply the agent, and the application cost is high.

Therefore, an object of the present invention is to solve the problems as described above by providing a tape of a connecting nail capable of reliably preventing the nail from falling off without causing tilting due to slip of the lower wall even when external pressure is applied to the nail. To provide.

[Means for Solving the Problems]

In order to solve the above problems, the present invention provides an upper wall and a lower wall that project in the same plane side above and below a side wall, and a nail holding portion is provided on each of the upper wall and the lower wall. The structure is provided so as to open at the side edge, and the thickness of the lower wall is partially thickened to the upper surface side at least at the position on the inner end side of the nail holding portion.

In this invention, it is possible to adopt a configuration in which the thickened portion of the lower wall is formed by a protrusion provided on the upper surface of the lower wall.

[Action]

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

As for the thickness of the lower wall, the inner end side of the holding part is thicker on the upper surface side, so the part that supports the nail on which the external pressure is applied to the side wall becomes vertically longer, and the supporting part is more than the upper surface of the lower wall. When the nail is extended upwards and therefore the lower wall is pressed by the external pressure applied to the nail on the side wall side, the nail is also subjected to pressing force at a position higher than the bending fulcrum of the lower wall and the side wall. As a result, a force is generated that pushes up the lower wall, which prevents the lower wall from tilting downward, and the holding part of the lower wall can maintain the state of holding the tip of the body part, making sure that the nail does not come off. Can be prevented.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4 of the accompanying drawings.

As shown in the figure, the tape 11 is made of a synthetic resin thin plate, and is bent toward the same side so that the upper wall 13 and the lower edge of the strip-shaped side wall 12 are opposed to each other at the upper and lower sides, respectively. A holding portion 15 for holding the head 9 side by the body portion 8 of the nail 7 is provided at a constant interval in the length direction so as to open at the side edge of the upper wall 13, and further between the holding portions 15. A notch 16 extending from the side edge to the side wall 12 is provided at the position.

The lower wall 14 is provided with a holding portion 17 for holding the tip side position of the body portion 8 of the nail 7 at a position facing each holding portion 15 of the upper wall 13 at regular intervals in the longitudinal direction. Notches 18 are provided so as to open at the side edges, and notches 18 extending from the side edges toward the side wall 12 are provided at positions between the holding portions 17.

The holding portions 15 and 17 provided on the upper wall 13 and the lower wall 14 are vertically opposed to each other, and have a circular hole into which the body portion 8 is elastically fitted, and an introduction notch extending from the circular hole to the outside. The example formed by the combination of is shown.

In the lower wall 14 of the tape 11, the thickness of the lower wall 14 is partially thickened toward the upper surface side at least at the position on the inner end side of the holding portion 17.

Specifically, by integrally providing a projection 23 along the width direction of the lower wall 14 at a position closer to the inner end of the holding portion 17 on the upper surface of the lower wall 14, the thickness of the lower wall 14 is partially moved to the upper surface side. It is thick.

The projection 23 is provided such that the front part surrounds the periphery of the holding part 17 and the rear end secures a gap between the side wall 12 and the lower wall 14 at a position closer to the side wall 12 by this gap. A thin portion 14a having a thickness of 14 is produced.

Although not shown, as a means for partially increasing the thickness of the lower wall 14 to the upper surface side, a separate narrow member is adhered to the lower wall 14 or the wall is formed so as to surround the holding portion. Means such as forming the thickness partially thick can be adopted, and in any case, the structure and the shape are shown as long as the inner end side portion of the holding portion 17 on the lower wall 14 projects to the upper surface side. It is not limited to.

The tape of the present invention has the above-mentioned structure, and as shown in FIG. 2, the head 8 side of the nail 7 is held by the body 8 of the nail 7.
The nail 7 is inserted into the holding portion 17 of the lower wall 14 while being inserted into the holding portion 15, and the nail 7 is held by the tape 11 at a constant interval to form a connecting nail.

As shown by the arrow A in FIG. 2, the side wall 12 is attached to the nail 7 held by the tape 11.
When an external pressure is applied to the upper wall 13 and the lower wall 14, the upper wall 13 and the lower wall 14 support the upper wall 13 and the lower wall 14.

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

Further, in the lower wall 14, the body portion 8 pushed by the external pressure is supported by the inner end side of the holding portion 17, but at this time, the body portion 8 is also supported by the portion of the projection 23 having a thickened upper surface side. As a result, the support range of the body portion 8 is extended above the upper surface of the lower wall 14.

As described above, when the lower wall 14 supports the nail 7 to which the external pressure is applied toward the side wall 12, the lower wall 14 tries to rotate downward with the bending point a with the side wall 12 as a fulcrum.

However, if a protrusion 23 for supporting the body portion 8 is provided on the upper surface of the lower wall 14 by increasing the thickness of the lower wall 14, the supporting portion by this protrusion 23 is a bending point a with the side wall 12 of the lower wall 14. Since it is located above the lower wall, as shown by arrow B in FIG.
The action to rotate 14 upward occurs.

Therefore, the force of expanding the lower wall 14 and the force of rotating the lower wall 14 are balanced and the lower wall 14
Does not slip on the tip side of the body portion 8.

Therefore, the lower wall 14 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 becomes possible.

[Effects] As described above, according to the present invention, since the nail holding portions of the upper wall and the lower wall are provided and the thickness of the lower wall is increased at least at the inner end side of the holding portion to the upper surface side, the nail Even if external pressure is applied to the side wall of the nail while it is being held, the thickened portion can prevent slipping of the lower wall toward the tip of the body, preventing the nail from falling and preventing the nail from falling. It enables continuous nailing.
