Abstract

PURPOSE: To provide a connecting fastener capable of being made at low cost and not only performing driving work safely but also processing simply without polluting the working enviroment. CONSTITUTION: An adhesive is applied on the surface of a connecting material 1 formed in a string by stranding a paper sheet and adhering a fastener 2 on the adhesive in the longitudinal direction of the connecting material 1 in equal intervals, while the adhesive strength of the fastener 2 is set weaker than the strength required to repture the connecting material 1 when the fastener 2 is driven through it.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting fastener in which a plurality of fasteners are bonded and connected to a thread-like connecting member.

[0002]

2. Description of the Related Art This type of connecting fastener is generally classified into one in which the fasteners are connected via wires, one in which they are connected via a plastic sheet, and one in which they are connected via a paper material.

The connecting fastener by wire connection is a method in which the fastener is spot-welded and connected to the wire, and thus the cost is low. However, since the connecting wire is broken when the fastener is driven, the connecting wire is broken. When it is driven into the material to be driven while being fixed to the fastener, the debris protrudes from the head of the fastener, so that the trace of the debris being driven remains in the driven portion, which is not preferable in terms of quality. If debris comes off the fastener when driving, it may fly around and damage your arm, etc.
There was a problem in work safety. In particular, a wood-based prefabricated manufacturer uses tens of thousands of nails and screws per day in a factory, and therefore it is desired that safety measures be perfect.

A connecting fastener using a plastic sheet is formed by bending a plastic sheet so as to have a rectangular cross section to form a connecting band, and passing each fastener from the upper piece to the lower piece of the connecting band for holding and connecting. Although there is no fear that the debris will scatter when the fastener is driven, there is a problem that the manufacturing cost is high, and a special incinerator is required when incinerating the connecting strip after use, so that the processing cost is also high.

Further, in the case where the paper material is used as the connecting material, the portion connecting the next fastener with the fastener is torn when the fastener is driven, and the hot melt is scattered. There was a drawback that the hot melt was scattered and the surroundings became dirty.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a connecting fastener which solves the above-mentioned drawbacks, is low in cost, can be driven in safely, can be processed easily without polluting the working environment. That is the purpose.

[0007]

In order to achieve the above-mentioned object, a connecting fastener according to the present invention has an adhesive applied on the surface of a connecting material formed by twisting papers into a string shape, and the adhesive is applied on the adhesive. The fastener is bonded at equal intervals in the longitudinal direction of the connecting material, and the adhesive force of the fastener is set to be smaller than the force required to break the connecting material when the fastener is driven.

[0008]

When the fastener is driven, the adhesive force of the fastener is set to be smaller than the force required to break the connecting member, so that only the fastener is driven and the connecting member is not broken.

[0009]

1 shows a connecting fastener according to the present invention, which is formed by adhering a plurality of fasteners 2 (nails) to a connecting member 1 at equal intervals.

The connecting member 1 is a cord-like body 1a formed by twisting paper.
Are arranged in six rows and adhered so as to form a strip shape. As shown in FIG. 2, the hot melt 3 is applied to one surface of the connecting material 1. The connecting member 1 has a high strength because it is composed of twisted paper.

Since the hot melt 3 is solid at room temperature, the layer of the hot melt 3 enhances the rigidity of the entire connecting material 1. Further, since the groove 4 between the two adjacent string-shaped bodies 1a serves as a glue reservoir for the hot melt 3, a thick layer of the hot melt 3 is formed in this portion as compared with the other portions.

The adhesive force of the fastener 2 is set to be smaller than the force required to break the connecting member 1 when the fastener 2 is driven. That is, the fastener 2 is set so as to be detached from the hot melt 3 without breaking the connecting material 1 when the fastener 2 is hit in the axial direction.

In the above-mentioned connecting fastener, the connecting material and the fasteners aligned at a constant interval are gradually moved closer to each other while moving at the same speed, and the fastener is applied to the connecting material 1 and heated and melted on the surface of the hot melt. It may be manufactured by a process in which the hot melt is cooled and solidified and the fasteners are instantly adhered after the contact with each other. Since such a bonding method is almost the same as the case where the fastener is spot-welded to the wire in the connection fastener of the wire connection method, it can be performed by the same method as the conventional wire connection.

Next, the connecting fastener having the above construction may be loaded into a nailing machine (not shown) and used in the same manner as the conventional wire connecting fastener. As shown in FIG. 3, when the driver 5 driven by the striking mechanism of the nailing machine strikes the frontmost fastener 2a of the connecting fastener to drive it into the driven material, the connecting material 1 is a twisted paper. Therefore, the strength is high and the fastener 2a and the hot melt 3 are set so as to be detached from each other before the connecting material 1 is broken. Therefore, the fastener 2 is detached from the connecting material 1 and is ejected. The connecting material 1 is sent in the feed direction of the connecting fastener as in the case of the connecting fastener using the conventional plastic sheet, and is collected after the connecting fastener is consumed.

The structure of the connecting member 1 is not limited to the above example. For example, as shown in FIG. 4, three cord-like bodies 1a formed by twisting paper into a cord shape are arranged and adhered to form a connecting member 1, and the connecting members 1 are arranged in parallel to each other to form a fastener. The two shaft portions may be connected and held at two places. If the diameter of the string-shaped body is made large, one string-shaped body may be used as the connecting material.

The fastener is not limited to the nail as in the above example. It may be a screw.

Similarly, the adhesive for the fastener is not limited to hot melt. Other adhesives may be used as long as they have the same adhesive strength.

[0018]

[Effect] As described above, according to the present invention, although the connecting material is made by twisting paper, since the adhesive is applied to the surface, the overall rigidity is high and the fastener is sufficiently retained. can do.

Further, since the connecting material is not broken when the fastener is driven, fragments are not scattered, the fastener can be driven safely, and the working environment is not polluted. Then, only the fastener is driven into the material to be driven, and no trace other than the fastener remains on the driven portion of the material to be driven, so that the finish is good.

Further, since the connecting member is made by twisting papers, the manufacturing cost is low, and the inexpensive connecting fastener can be provided.

Although only the connecting material remains after the connecting fastener is used, it is sufficient to incinerate it, and since it is paper, it is not necessary to use a special incinerator.
