Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device which is normally inserted into an article to fix two articles together, and more specifically, a tag such as a tag or a label is a commodity such as clothes. The present invention relates to an assembly of locking members made of synthetic resin for easily fixing to a fastener.

[0002]

2. Description of the Related Art A locking tool made of synthetic resin is, for example, 1963.
U.S. Pat. No. 3,103,66, issued September 16, 2016
No. 6 proposed, many inventions and inventions have been made in relation to this locking tool, and many have come to be used. Since the fastener itself is extremely small, it is substantially inconvenient to manufacture it and attach it to the product.
It is necessary to manufacture 5, 50, and in some cases 75 to 100 as a fastener assembly and handle it.
Many inventions and ideas have been made in this connection.

As an example of improving the locking tool assembly disclosed in the above-mentioned US patent, for example, FIG. 6 (Japanese Patent Publication No. 52-202).
No. 40), a head portion 11, a filament portion 12 extending from the center of the head portion 11, and a horizontal bar portion fixed to one end of the filament portion 12 and arranged in parallel with the head portion 11. The locking tool configured in this way, which is composed of 13, is connected to the connecting rod 15 via the connecting piece 14, and the heads 11 are cutably connected by the fixing member 16 to provide a locking tool assembly. By constructing the body, entanglement of the fasteners is prevented.

Now, as described in Japanese Patent Publication No. 52-20240, the conventional fastener assembly must be constructed by connecting the fastener to the connecting rod 15 via the connecting piece 14. Therefore, the connecting piece 14 and the connecting rod 15 are indispensable in the conventional fastener assembly. Further, the connecting piece 14 not only serves to connect the locking tool to the connecting rod 15, but also acts as a feeding member when supplying the locking tool assembly to the gun. It was a necessary member as long as

As described above, the connecting rod 15 has a function of arranging a large number of fasteners in a comb shape. This serves as the spine as an assembly and also as a runner in the molding process. It fulfills its function. For example, the weight of the fastener assembly in which 35 nylon fasteners are connected to the connecting rod via the fastener is 1.3 g. The weight is 0.14 to 0.20 g, and after all, 11 to 15% of the total weight of the fastener assembly is the weight of the connecting rod and the connecting piece.

On the other hand, the connecting rod and the connecting piece are members that are discarded when the locking tool is attached to the product along with the label and the tag, and are wasteful parts. Therefore, it is preferable that the connecting rod and the connecting piece are not provided at least from the viewpoint of using the locking tool. Further, this connecting rod gradually protrudes from below the guide groove provided in the gun as the locking tool is driven by the gun, but this connecting rod has a connecting piece after the locking tool is cut off by a blade. It will protrude in a comb shape. This connecting piece is sharply pointed, and it will gradually project downward of the front of the gun as the locking tool is driven, and there is a risk that this will get caught in the product and damage the product, operating the gun. There was a problem that we had to be careful when doing.

As another known example, a large number of fasteners themselves are arranged, and the head and the edge of the horizontal bar having a square cross section are adhered by an adhesive to gather them in the shape of a stapler needle. Although a body has been proposed, it is substantially difficult to bond the fastener with an adhesive that is a material other than the synthetic resin that constitutes the fastener in this way, and the productivity is remarkably inferior. It is often difficult to implement due to various factors such as the degree of adhesion of the adhesive, the adhesive strength and the drying speed.

As another known example, JP-A-57-510
According to the publication No. 13, locking devices are arranged densely, and the center of the horizontal bar portion is arranged.

[0013]

A locking tool assembly according to the present invention has a horizontal bar portion which has a thickest central portion and is tapered toward both ends, and extends from the central portion of the horizontal rod portion. It is an assembly in which a plurality of H-shaped fasteners each including a formed filament portion and a head portion fixed to the end portion of the filament portion so as to face the horizontal bar portion are assembled, and the entire assembly is made of a thermoplastic material. resin is molded integrally with, the connecting the head comrades adjacent at one point on the extension destination of the filament portion, the laterally adjacent connecting the transverse bar portion adjacent at the central part Form a sharp triangular gap between the bars,
The thin plate-shaped connecting member extending in the central part or al both endwise of the horizontal bar portion to the small gap provided, the connecting member is characterized by having a strength in which the transverse bar portion can hold the position to each other .

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a locking tool assembly according to an embodiment of the present invention, FIG. 2 is a side view, and FIG. 3 is a plan view showing a connecting body. A locking tool t is a head i and a filament portion 2 is shown. And a horizontal bar 3 whose central portion is thickest and which is gradually narrowed toward both ends, is arranged in an "H-shape".
Is a set of a plurality of the locking tools t.

The locking tool assembly T is wholly integrally formed of a thermoplastic resin such as nylon or polypropylene. The head portion 1 is projected from the edge portion toward the center portion, and the vertexes 5 facing each other are connected to each other at one point of the extension portion of the filament portion 2. It is important in the present invention, as specifically shown in FIG. 3, are connected at one point 3a of thickest center part lateral bar portions 3, 3 of adjacent tapered, thus between the transverse bars 3 and 3 This is to form two triangular small gaps that are sharp in plan view, and to provide a thin plate-shaped, for example, film-shaped connecting body 4 in the small gaps. Horizontal bar part 3, 3. ... are connected as if they were one sheet .

Note that FIG. 3 is for facilitating the understanding of the connecting body 4, and since the horizontal bar portion 3 is drawn in an extremely tapered shape, the area of the connecting body 4 looks large, but in reality, In this locking tool assembly, the connecting body 4 is constituted by a triangular small area, and therefore, after the connecting body 4 is cut as described later, the connecting body 4 is attached to the side surface of the horizontal bar portion 3. left to those of the degree to substantially problem is not even.

The function of this connecting body 4 is to make it a kind of flow path of the molten thermoplastic resin when molding the horizontal bar portion 3 and to make the locking tool assembly T compactly assembled at the time of packing and handling.
It is intended to summarize Te, but are not cut in the production process and packaging process, are easily cut when that implanted fastener t to product, connector 4 has remained more on the side surface of the horizontal bar portion 3 Even in such a case, it is necessary that the item is minute and does not damage the product. Further, the horizontal bar portion 3 in a state where the locking member t is set are arranged in a sheet shape via the connecting member 4, and the intensity of the degree the connecting body 4, the transverse bar portion 3 can hold its position to each other It is necessary to have

The length of the connecting member 4 is a best to form the entire length of the horizontal bar portion 3 as shown in FIGS. 2 and 3, this
The original function of the coupling member 4 of, such that the lateral bar portion 3 does not wobble while a large number of locking tool constructed aggregates collectively, central or found both ends of the horizontal bar portion 3 It extends in a direction
It suffices to form it , and therefore, 1/2, 1/3 of the horizontal bar portion 3,
Various lengths such as 2/3, 3/4 ... can be selected,
It is preferably 1/3 or more. In any case, a large number of locking tools are well assembled, and are easily cut when the locking tools are driven, and it is necessary to prevent the remaining portion of the horizontal bar portion 4 from being cut as much as possible. By forming the end surface of the connecting body 4 into a U-shape 4a as shown in FIG. 3, as will be described later, insertion and cutting of a blade at the time of cutting become easy.

[0019] The thickness of the connecting body 4 is substantially constant as shown in FIG. Incidentally, if Okere to form an inclined surface 6 to the end of the horizontal bar portion 3, for insertion between the crossbar unit 3, 3 of two adjacent member (blade) for cutting the continuous body 4 There is an advantage to guide us. Above As mentioned, a number of horizontal bars 3 in the locking tool assembly of the present invention is distribution <br/> column substantially close contact state, these horizontal bars 3 central one point 3a Connected by
In addition, the sheet is further connected in a sheet-like manner (like a stapler needle) so that it can be cut by the connecting body 4.

The connecting body 4 can be cut by pressing the horizontal rod portion 3 into a hollow needle provided at the tip of the gun by pressing it against a knife (knife) or the like provided at its inlet portion. . Further, as a completely new cutting machine groove, for example, FIG.
, The horizontal rod portion A, B, C, ... Is connected by the connecting body 4 to move in the guide groove 6 of the gun in the direction indicated by the arrow X, and the leftmost horizontal rod portion A is driven into the hollow needle 7. when it is, before piston which is operated by the lever of the gun the lateral bar portion a by positioning the center of the push-up Gaité opening of the hollow needle 7 as shown by an arrow Y
It is pushed into the hollow needle 7, but in this series of operations, since the horizontal rod portions B, C ... Following the horizontal rod portion A are located in the guide groove 6, the horizontal rod portions A and B are The connecting body 4A connecting between and is cut when the horizontal bar portion A is pushed up in the direction of the arrow Y.

As a result, according to the present invention, adjacent head portions are connected to each other substantially at one point, and adjacent horizontal bar portions are arranged at the center thereof.
In part, because they are connected to each other by a connecting member while being connected, that by external force acts on the locking tool assembly in the manufacturing process and packaging process, to prevent the aggregates to decompose apart it can. Even coupling head each other are destroyed the example connected, by connecting member and the connecting of the lateral bar portion mutually
Concatenation horizontal bar portion comrades can hold its position to each other, it can be sufficiently used as a fastener assembly.

Therefore, when the fastener assembly of the present invention is loaded into the gun, the assembly is loaded into the gun in a compact state.
And is held stable. While driving the lock
If the assembly loaded in the container swings, it will be a major obstacle to the operation of continuously striking a large number of products, etc.
Work efficiency is significantly reduced. Further, the mutual positions of the horizontal bar portions are not held constant, and for example, if they are twisted, it becomes impossible to sequentially feed the fastener assembly to the gun as the fastener is driven into the product, At the twisted portion, the connecting body is cut, and the aggregate is broken. Only
However , according to the present invention, such a trouble can be eliminated.

Further, since the connecting body has a length and a width, it is easy to manufacture the mold, and the pressure in the mold during molding is equalized.
It is possible to prevent the damage of the mold by playing the role of the flow path . Further, unlike the conventional assembly, since the horizontal bar portion is not connected to the connecting rod via the connecting piece, the resin required for these connecting pieces and the connecting rod can be saved.

Furthermore, when attaching a locking piece to a product or the like,
Sharpness and connecting rod after the fastener has been driven in the conventional assembly
There is a drawback that the connecting piece having a good tip remains, and these members project from the lower portion of the tip of the gun to damage the product or the like. However, since the assembly of the present invention does not require a connecting piece or a connecting rod, such a drawback can be eliminated.

Further, since a connecting piece and a connecting rod, which are required in the conventional assembly, are not required, and the head and the horizontal bar portion adjacent to each other are connected, the assembly becomes compact and the molten resin at the time of molding is formed. The flow becomes good, and the generation of defective products due to poor resin flow can be prevented.
