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]

As shown in FIG. 6, the connecting nail used in the above-mentioned nail driver is
A long tape 1 has a structure in which a large number of nails 7 are held in parallel at regular intervals.

As shown in the same figure, the conventional tape 1 uses a thin plate made of synthetic resin, and an upper wall 3 and a lower wall 4 for holding above and below the strip-shaped side wall 2.
Are bent to face each other and are formed in a U-shape in cross section, and holding portions 5 and 6 for supporting the body portion 8 of the nail 7 at a position where the upper wall 3 and the lower wall 4 face each other.
Are provided 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. The holding portions 5 and 6 are formed by straight circular holes penetrating in the vertical direction.

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 portion to insert the tape 1. Will be held at.

[Problems to be Solved by the Invention] Since the conventional tape 1 is formed into a U-shaped cross section by bending a thin strip of synthetic resin, the upper wall 3 and the lower wall 4 can be expanded freely. Since the habit of the opening direction remains, when the external pressure is applied to the nail 7 held by the tape 1 toward the side wall 2 side during the transportation and the operation of the connecting nail, the upper wall 3 and the lower wall 4 are pushed open. It will be.

As described above, when external pressure is applied to the side wall 2 side of 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 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,
As shown in FIG. 7, external pressure applied to the nail 7 causes the lower wall 4 to move to the body portion 8.
There is a problem in that the holder 6 slips toward the tip side of the tape and tilts, the holding section 6 separates from the moving section 8, the tip side of the moving section 8 falls off the tape 1, and nailing with a nailing machine becomes 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 it requires expensive equipment and application cost.

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. Adopting a structure in which the nail is provided so as to open at the side edge, and at least the position of the inner end portion of the inner peripheral edge of the nail holding portion provided on the lower wall is inclined in the direction away from the nail from the upper surface to the lower surface. Is.

[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.

Since at least the inner end of the holding portion of the lower wall is inclined, the portion supporting the nail to which the external pressure is applied to the side wall is biased toward the upper surface side of the lower wall, and therefore the external pressure to the side wall side is applied to the nail. When the lower wall is added and pressed, a pressing force is applied at a position above the bending fulcrum of the lower wall and the side wall, and therefore a force in the direction of pushing up the lower wall is generated. It is possible to prevent downward tilting, maintain the state of holding the front end of the body portion by the holding portion of the lower wall, and reliably prevent the nail from falling off.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5 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 are bent toward the upper surface of the strip-shaped side wall 12 and the lower wall 14 so as to face each other in the same direction.
A holding portion 15 for holding the head 9 side with 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 between the holding portions 15 further. A notch 16 extending from the side edge toward the side wall 12 is provided at the position.

The lower wall 14 has a holding portion 17 for holding the tip side position of the body portion 8 of the nail 7 at a position corresponding to each holding portion 15 of the upper wall 13 at regular intervals in the longitudinal direction. A notch 18 is provided so as to open at the side edge, and a notch 18 extending from the side edge toward the side wall 12 is provided at a position between the holding portions 17.

The holding portions 15 and 17 provided on the upper wall 13 and the lower wall 14 are opposed to each other in the vertical direction, and as shown in FIG. 4, a circular hole 19 into which the body portion 8 is elastically fitted and a continuous circular hole 19 are formed. The example formed by the combination with the introduction notch 20 which expands outside is shown.

In the lower wall 14 of the tape 11, the circular hole 19 of the holding portion 17 provided in the lower wall 14 is such that the position of at least the inner end of the circular hole 19 in the inner peripheral edge of the circular hole 19 is away from the nail 7 from the upper surface to the lower surface. It has an inclined surface 21.

Due to this inclined surface 21, the lower wall 14 is biased to a position where the support contact of the nail 7 which receives external pressure in the inward pushing direction is equal to the upper surface of the lower wall 14.

In the case of FIG. 4, the inclined surface 21 is shown as being formed on the inner peripheral surface of the circular hole 19 over substantially the half circumference on the inner end side, but by punching the circular hole 19 in an inclined manner, the entire inner peripheral surface is formed. You may make it have a slope.

Further, as shown in FIG. 5, the holding portion 1 provided on the upper wall 13
Similarly to the holding portion 17 of the lower wall 14, the inclined surface 21 may be formed at the position of the inner end of the lower portion 5.

The tape of the present invention has the above-described structure. As shown in FIG. 2, the head 9 side of the nail 7 is pushed into the holding portion 15 of the upper wall 13 by the body portion 8 of the nail 7 and the tip end side is inserted. The tape 11 is pushed by being inserted into the holding portion 17 of the lower wall 14.
Then, the nails 7 are held at a constant interval to form a connecting nail.

When an external pressure acts on the nail 7 held by the tape 11 toward the side wall 12 as shown by an arrow A in FIG. 2, the upper wall 13 and the lower wall 14
Will support this.

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 pressed by the external pressure is supported by the inner end portion of the holding portion 17.
The position of the inner end on the inner peripheral edge of the nail 7 is from the upper surface to the lower surface.
Since it is the inclined surface 2 in the direction away from, the contact point of the nail 7 is evenly offset to the upper surface of the lower wall 14.

By the way, the lower wall 1 which supports the nail 7 pushed by the external pressure
4 indicates that when the contact point of the nail 7 is offset to the upper end portion of the vertical thickness by the inclined surface 21, the vertical direction of the inclined surface 21 tries to move along the length direction of the nail 7, which means that 14
There is an action of trying to rotate upward with the bending point a as a fulcrum.

Therefore, the force to expand the lower wall 14 below,
The forces that try to rotate the lower wall 14 upward are balanced, and the lower wall 14 will not slip to 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.

〔effect〕

As described above, according to the present invention, the nail holding portions are provided on the upper wall and the lower wall, and the position of the inner end portion of the holding portion on the lower wall is inclined from the upper surface to the lower surface in the direction away from the nail. Therefore, even if external pressure is applied to the side wall of the nail while the nail is being held, slip movement toward the tip of the lower wall can be prevented at the top contact point of the inclined surface, and the nail does not fall off. It is possible to prevent nails from being continuously nailed.
