Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an improvement in a sealing device used for connecting multiple items together, for example, attaching price tags to products, or connecting slippers, shoes, etc. of footwear. More specifically, it relates to a locking mechanism for a sealing device.

[Prior Art] Recently, synthetic resin sealing tools have been used to connect slippers and sandals, which are exemplified as a plurality of products as described above, or products and price tags, labels, etc., or to bundle bar-shaped materials. has come to be used. This is thought to be due to the fact that it can be integrally molded with synthetic resin and has excellent productivity, as well as its workability is superior to the long-known sealing using thread or string.

The sealing device has a connecting portion and a head into which the connecting portion is inserted at both ends of a filament of a certain length, and after inserting a plurality of articles to be connected to the filament, the connecting portion is inserted into the head. The plurality of articles were connected by inserting the articles in such a way that they could not be separated.

Due to the above-mentioned connection, it is not possible to separate the connected state without destroying the connection mechanism, so focusing on the effect of preventing the connected items from being unreasonably separated, it is possible to attach product displays, signs, etc., or separate the pair. It has been used for a variety of purposes, including preventing the accidental dispersion of objects and their loss.

As such a sealing tool, for example,
Publication No. 8473 (sealing device), Publication Utility Model Publication No. 55-26306 (synthetic resin sealing device), or Publication No. 18209 of Utility Model Publication No. 8473 (sealing device)
Publication No. (synthetic resin sealing device), and also Jikko 57
It is known through Publication No. 4617 (sealing device).

[Problems to be solved by the invention] However, these sealing tools are inevitably formed to be extremely thick compared to the filament in order to provide a locking function at all of the connecting parts (the tip of the filament). There is.

Among the conventional examples mentioned above,
If I were to explain the idea described in the publication as a representative example,
As shown in FIG. 8, a stopper 6 is provided to prevent the connecting portion 3 from jumping out in the insertion direction of the head 1 when the connecting portion 3 is inserted into the head 1 by manual labor. ing.

Further, the connecting portion 3 is formed to have a larger diameter than the neck portion 3a, and the stopper 6
is formed with an even larger diameter.

The diameter of the connecting portion 3 must withstand a predetermined loop tensile strength when the sealing device is formed into a loop, and since these sealing devices are made of synthetic resin such as nylon or polypropylene, the diameter of the connecting portion 3 is not large enough. If the filament is too small, it will easily collapse when external force is applied to it, so the diameter of the stopper 6 is usually about 3.5 to 4.5 times the thickness of the filament, and therefore the diameter of the stopper 6 is also made larger. There is.

In addition, since this type of sealing device is joined by hand, in order to make it easier to insert the joining part 3 into the head 1, an enlarged holding part 6b is formed that is large enough to be pinched by hand, and the joining work is done by hand. The connecting portion from the portion 3 to the enlarged holding portion 6b, that is, the neck portions 3a and 6a, is provided with rigidity so as to withstand the bonding force between the connecting portion 3 and the head 1. That is, the conventional sealing device has a large connecting portion, and therefore, it is difficult to use it for products that do not have a hole suitable for inserting the connecting portion in advance, such as slippers or shoes. Or, since the rigidity between the joint part 3 and the enlarged holding part 6b is large, when a load is applied from the direction of the enlarged holding part 6b toward the joint part 3 side, the joint part 3 will move away from the head 1 along the imaginary line. As shown, it slips out, so in reality,
Since the stopper 6 and the enlarged holding portion 6b cannot be removed, this device can only be used for joining articles with holes.

Therefore, in the present invention, the part corresponding to the connecting part is thin until it is inserted into the head, and it can be made thicker when it is connected to the back of the head. By making it possible to use a guide needle, even if the object to be attached is non-perforated, the purpose of use can be satisfactorily achieved by making a hole with this guide needle. It is an object of the present invention to provide a sealing device that can obtain sufficient strength in a bonded state.

[Means for Solving the Problem] The present invention to achieve this object provides a storage hole and an introduction hole smaller than the storage hole in the head, extends the filament from the head, and A horizontal bar is disposed at the other end substantially perpendicular thereto, and a cross-sectional area of the horizontal bar near the intersection with the filament is formed to be smaller than a cross-sectional area of other parts of the horizontal bar; The sealing device is characterized in that the widthwise dimension of the storage hole is formed to a dimension that allows the horizontal bar to be press-fitted in a folded state with a pressing force stronger than the buckling force of the filament.

[Operation] The present invention uses the above-mentioned means, for example, attaching a label such as a quality indication to the cuff of clothes, and inserting and pushing one end of the horizontal bar using an appropriate means, such as a guide needle. As a result, the side end protruding toward the opposing surface is guided and pushed through the introduction hole of the head to the storage hole.

Once the horizontal bar is exposed to the outside of the storage hole, when the horizontal bar is pulled in the opposite direction through the filament, it is folded in half and press-fitted into the storage hole in a folded state. That is, the insertion work can be carried out with the connecting portion in the conventional example in a thin state until it is inserted into the head, and after the head is inserted, the connecting portion can be in the same state as the thick one.

Therefore, it is greatly different from conventional sealing tools of this type in that it can be installed when the object to be installed is non-porous, and even if the filament is pressed and swung back and forth and left and right by applying external force, Since the storage is maintained in a tightly inserted state, the filament is only bent, and the horizontal bar is not released from the storage hole, and the desired connection state can be maintained for a long time while obtaining the desired strength. It is something.

[Example] Hereinafter, a preferred embodiment of the present invention will be described in more detail based on the drawings.

Fig. 1 shows an example of the sealing device; Fig. 1a shows a partially cutaway side view, Fig. 2b shows a front view, and Fig. 2 shows a state in which a plurality of sealing devices are successively implanted on a connecting rod. Fig. 3 is a side view of Fig. 2, Fig. 4 is an explanatory drawing showing the state of the sealing operation, Fig. 5 is an explanatory drawing showing the state of the head in the sealing state, Fig. 6 is a cloth umbrella Fig. 7 is an explanatory diagram showing how the side end of the horizontal bar protruding through the fabric seam allowance is being inserted into the head of the umbrella, which is located across the ribs of the umbrella. , FIG. 8 is an explanatory diagram showing a conventional sealing device.

The illustrated sealing device consists of a head 1, a filament 2, and a horizontal bar 3. The cylindrical head 1 has a storage hole 11 at one end thereof, and a hole 11 smaller than the storage hole 11 at the other end. Introductory holes 12 are formed and communicated with each other.

Preferably, the introduction hole 12 has a cone-shaped tapered surface suitable for facilitating insertion of the horizontal bar 3.
In order to make the horizontal bar 3 foldable, for example, a notch 31 as shown in the figure is provided so that the cross-sectional area of the bent portion of the horizontal bar 3 is larger than the cross-sectional area of the other portion of the horizontal bar 3. Make it smaller and easier to fold. Note that the sealing device S formed in this way is preferably made of soft metal, synthetic resin, or synthetic rubber from the viewpoint of material, and from the viewpoint of shape,
The shape of the head 1 and the horizontal bar 3 when viewed from the front is preferably cylindrical or polygonal.

Further, it is necessary to form the maximum dimension of the horizontal bar 3 in a folded state through the notch 31 to be slightly larger than that of the storage hole 11. this is,
This is to press-fit the horizontal bar 3, which is folded in half, into the storage hole 11. However, it is good to be able to obtain a pressure contact force that is stronger than the minimum compressive force at which this phenomenon occurs.

The horizontal bar 3 is arranged parallel to the axial direction of the storage hole 11. The head 1 and the horizontal bar 3 arranged in this manner are connected by a filament 2 to form a sealing device S.

From the viewpoint of efficiency, it is preferable that a plurality of sealing devices S be installed in a series on the connecting rod 4 and then installed in a mounting machine, which will be described later, to carry out the mounting work. In this case, a suitable configuration is such that the horizontal bar 3 is disposed perpendicular to the connecting rod 4, and if the horizontal bar 3 has a notch 31, the filament 2 is connected to the connecting portion near the edge of the notch. A plurality of sealing device groups S ₁ , S ₂ ...Sn are connected to the connecting rod 4 by connecting portions 5 extending in parallel and opposite directions
be planted in

Sealing device groups S ₁ , S ₂ ...Sn installed on the connecting rod 4
The number of connecting rods is usually 10 to 50 or more in one connecting rod, and they are preferably integrally molded from nylon or other synthetic resin.

The connecting part 5 is formed to have a narrow cross-sectional area near the connecting end 5a with the horizontal bar 3, so that it can be easily separated from the mounting machine as described later.

The shape of the connecting part 5 in FIG. 2 is not limited to the illustrated example, and is omitted from illustration.
The connecting end 5a has a truncated cone shape, for example, a truncated cone,
It can be shaped into a truncated triangular pyramid, a truncated square pyramid, or a truncated hexagonal pyramid.

In Figures 4 and 5, P is a push rod and Q is a guide needle.
31697 (see Publication No. 31697), the horizontal bar 3 is guided into the guide needle Q by the push bar P, and is made to penetrate the article, for example, the cuff Y of clothes and the label L indicating the quality.

That is, for example, the sealing device group S ₁ shown in FIG.
S ₂ ...When the horizontal bar 3 is pushed into the guide needle Q while being separated by the push bar P at the position shown by the solid line in Fig. 4 from Sn, the horizontal bar 3 passes through the clothes cuff Y and the label L. As shown by the line, filament 2
moves while bending parallel to the horizontal bar 3 and passes through the clothes cuff Y and the label L.

Note that, prior to this, if the head 1 is positioned at the illustrated position with a finger or a mechanically actuated lever (not shown), the horizontal bar that has passed through the guide needle Q will be
It passes through the introduction hole and the storage hole 11 in the head, and once comes out and restores itself, forming a T-shape as shown by the imaginary line. That is, the horizontal bar 3 remains in a thin state until it exits from the storage hole 11 of the head 1. Next, when pulling out the guide needle Q from the clothes cuff Y and label L, if the filament 2 is pulled in the opposite direction to the insertion direction of the horizontal bar 3 by a mechanism not shown, then T
The character-shaped horizontal bar 3 gradually becomes Y-shaped, folds in half, and is press-fitted into the storage hole 11, and then the fifth
The state shown in the figure will be reached.

As described above, this press-fit state is a press-fit state that is stronger than the buckling force of the filament 2, and since the horizontal bar 3 is folded in half, a force is applied to the filament 2 in the direction of pulling the horizontal bar 3. In this case, there are two engaging parts of the horizontal bar 3 that engage with the stepped parts of the storage hole 11 and the introduction hole 12, so the force supported by the engaging part of the horizontal bar 3 at one location is equal to the pulling force. 1/
2, it has an engagement strength comparable to that of a thick horizontal bar 3 that is folded in half and made into one solid piece.

In addition, when the sealing tool S does not use the above-mentioned installation machine, it is also possible to perform the installation work manually as a single item.

6 and 7 show other examples of use, where U shows a cloth umbrella, B shows the ribs of the umbrella, C shows the fabric of the umbrella, and N shows the seam allowance of the fabric C.

To explain this usage example, the conventional umbrella is
The bone B and the fabric C are fastened together with a thread, but in order to prevent the fabric C from shifting, it is necessary to loosely fasten the thread to the bone, which requires skill and requires a lot of time.

If the sealing tool of the present invention is adopted, the sealing tool S located at the position shown by the imaginary line in FIG.
By attaching it in the same manner as shown in the figure, slack can be given to the filament 2.

That is, by press-fitting and storing the horizontal bar 3 in the storage hole 11, the ring of the filament 2 can be made slightly larger, so even if the operator is inexperienced, the bone will not be tightened, and this work can be done in a short time. I can do it.

Furthermore, in another embodiment of the present invention, the connecting rod 4 and the connecting part 5 can be omitted.

In this case, a connecting member (not shown) may be provided to sequentially connect the central portions of the horizontal bars 3 in the right angle direction. Regarding the specific structure of the connecting member, for example, see Japanese Patent Application Laid-open No. 57-683 (Binding material aggregate).
Those shown in are preferred.

In the above embodiment, since the horizontal bar 3 is folded through the notch 31, the horizontal bar 3 is always folded in half in a well-balanced state, and the side end of the horizontal bar 3 is placed outside the storage hole 11 that is tightly inserted. Not only does it have a good appearance without exposing the material, but there is no risk of fabric fraying or abrasions when used as a sealant for labels, price tags, etc. on delicate and easily damaged clothing. .

Further, since the head 1 itself can be formed into a small size, there is no risk of the same problem as described above occurring when it is attached to clothing, and the molding operation is easy and simple.
It is highly economical and advantageous in terms of material cost.

Furthermore, from the viewpoint of sealing work, the operating procedure is simple, so it can be used efficiently and conveniently in any work environment, and can be carried out without requiring special skill.

Furthermore, if a known attachment machine is used, the horizontal bar can be inserted and pushed into the objects to be connected efficiently and reliably using the push bar of the machine.

The application of the present sealing device is not limited to the apparel industry, but can also be applied to a wide range of fields, including the connection between the fabric and bones of the cloth umbrella shown in the example, as well as the livestock and fishery fields. It is.

[Effects of the invention] The sealing device of the present invention, when connecting a plurality of articles to each other, allows the horizontal bar to be exposed outside the storage hole through the introduction hole in the head, and then to be pulled in the opposite direction. Therefore, the horizontal bar is folded and press-fitted into the storage hole, resulting in a tightly inserted state.In other words, the horizontal bar corresponding to the connecting portion is in a thin state until it is inserted into the head. In addition, in the combined state, the horizontal bar can be folded in half to make it thicker, so a guide needle can be used when passing the horizontal bar through the object to be attached and the head, and the object to be attached is free. Not only can the holes be used satisfactorily, but also the strength can be improved in the bonded state.
