Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector for a synthetic resin luggage band.

When packaging a product in a cardboard box, the cardboard box is further tied with string from the top. In particular, when packaging for transportation, synthetic resin bands have recently been used to tighten the bag instead of the traditional rice strings5. A band used for such purposes is a packing band made of synthetic resin. This band is made of polyolefin or synthetic polypropylene and is often used as a band, and is usually called a polyglo band.

This band has a width of approximately /θ-2θ and a thickness of 0. / The size below is often used. This band has a regular uneven pattern on both the front and back sides to prevent it from slipping when packing. Although the band can be bent, it is generally rigid and elastic and therefore cannot be tied like a string. To connect the bands together when packing, either overlap the bands and caulk the overlapped part with a metal band from the outside, or melt the overlapped part with heat to make it one piece. That was done.

However, both 9, which is caulked with a metal band, and K, which is heat-sealed, require special tools.

Therefore, there was a drawback that band connection could not be easily performed. Therefore, it was necessary to further improve this point.

The inventor focused on the fact that synthetic resin packing bands have irregularities on both the front and back sides to make them difficult to slip, and set out to create a connector that can be fixed simply by passing the packing band through.

This is how the connector according to the present invention was born.

The present invention uses a connecting device consisting of at least seven plate-like bodies. The plate-like body has two slits at at least one end, into which a synthetic resin packing band is folded and bent. In addition, when the band is folded back and bent, the front and back sides of the folded portion are overlapped and brought into close contact, and the uneven pattern of the band prevents the band from slipping. The main idea is to provide a groove and add uneven protrusions here to make the band more slippery.

Gold with a slit to insert the tape as a fastener for cloth tape, etc.! J4 products are already known. Metal ones were made by punching slits into an iron plate such as tin. However, this type of fastener was not satisfactory because if a synthetic resin packing band was inserted into the gap and tightened strongly, the band would crack vertically.

This invention consists of a plate-shaped body having at least one end thereof an insertion part for a synthetic resin packing band, and the insertion part has at least two parts.
At least 7 of the slits are parallel to each other, overlapping each other, and the wall surfaces located on one side of at least 7 of the slits are parallel to the plate surface. This invention relates to a connector for a synthetic resin packing band, characterized in that the ridgeline of an acute angle formed by the intersection of a wall surface and a board surface is provided with irregularities.

The present invention will be explained as follows based on the drawings. FIG. 1 is a partially cutaway exploded perspective view of a synthetic resin packing band connector according to Jin's invention. FIG. 2 is a partially cutaway perspective view of another connector according to the invention. FIG. 3 is a partially cutaway exploded perspective view of still another connection related to this generator 151.

FIG. 7 is a perspective view showing the state in which the connector according to the present invention is used.

In the first factor, the synthetic resin packing strap connection according to the invention is made of two elements & and b. The element a is provided with two locking pieces/and 2, and the locking pieces/and 2 can be inserted into the empty fIJ of the element. In the process of inserting the locking piece/and into the cavity 3, the protrusion/
/ and /2 are pushed from both sides and advance with the interval narrowed.

At the end of the insertion, the VCI/i, the protrusion // and 7.2 are restored, fit into the side holes of the element, and are locked in the side holes.

In this way, the element & is fixed within the element.

With element a fixed in the element case, when side rods j and g located on both sides of the element case are pulled toward each other, element a easily comes out of the element case. That is, when the side bars 5 and Ik are pulled together, the suppressing pieces j/ and 1/-! which are protruding from the inside of the side bars j and g! tE, the sides of protrusions // and /2 of element a are pushed and the locking pieces / and /2 are drawn together, so that protrusions // and /2 escape from the side holes. In this state, the pressing pieces j/ and 2/ further press the tapered side surfaces of the protrusions // and /j, so that the protrusions // and /2
The tapered slope of the side surface allows element a#i to escape from the element.

Elements a and b are both made of plate-shaped bodies, and each element a and b is made detachable by the mechanism described above. The seven elements a are constructed so that, when connected to each other, they have approximately the same thickness K as a whole. Roughly speaking, the thickness is several cods, specifically #i, 2Il @ or /Q
It is within the range of defeat cod.

Thereon, there are provided one each of elements a and bFi, and an insertion part for a synthetic resin packing band at the end opposite to the above-mentioned attachment/detachment part.

The passage of the packing band includes at least two slots 2/22. Slits 2/ and 2.2 are provided close to each other, overlapping and parallel to each other, and extend approximately perpendicular to the direction of movement during attachment and detachment of elements a and b. Wall surfaces 2 located on one side of at least seven gaps 21 among the gaps
Also, Fil/ is inclined with respect to the plate surface p. Furthermore, the ridgeline portion 2j or Fi? of the acute angle formed by the wall surfaces 23 and 2da intersect with the plate surface p? 1K unevenness is attached so that the band can be locked on the edge. However, in the example shown in FIG. 1, all of the acute-angled ridgeline portions are provided with concavities and convexities to ensure secure locking.

The connector shown in FIG. 1 is used with pressure as follows.

First, the synthetic resin packing band T is wound inside the narrow B12/2.2 as shown in the first factor. That is, seven bands are sharply bent and bent at the uneven ridgeline parts 2j and 2g, the band ends are at least partially overlapped and protrude from the element, and the uneven band surfaces overlap. such that the portion extends over at least the convergence of the band, preferably more than twice the width of the band,
attached to each element a and b. Then, the band T and elements a and bf are positioned so that the electrical part of the band surface comes into close contact with the surface of the item to be packaged. Next, by inserting the locking piece/2 into the cavity J and connecting the elements a and seven, the band TFi is securely fixed to each element a and b.

Connector C in Figure 2 is not made of two elements;
It differs greatly from the one shown in FIG. 7 in that it is made of only one element. In other respects, it is almost the same as the connector shown in Fig. 1 of Company C. That is, the connector C is made up of seven plate-shaped bodies, and is provided with insertion portions for synthetic resin packing bands at both ends.

The insertion part includes two slots 11j7/ and 2.2, and each slot 2/ and 7.2#-1 are provided in parallel so as to approach each other and overlap. Among the slits 2/ and 2.2, the wall surface 2J or 2d where at least one piece of at least seven of the slits is located at wa is inclined with respect to the plate surface p, and the wall surface 23 or 2d is located at the plate surface Acute angle ridgeline part 2 created by intersecting with p
Irregularities are attached to j and 2g. In addition, the acute angle edge line portions 22 and 7J' are also provided with irregularities.

The fitting of FIG. 3 is made up of two elements d and e. If element d is provided with two locking pieces/and 2, then 7 is the same as element false in FIG. 1, but in addition, element a#
It is equipped with an i-induction rod F. In addition, the locking piece/and 2 are
The protrusions // and 7.2 are fitted into the side holes in the cavity 3 of the element d.
The mechanism for preventing the element e from escaping is the same as that in FIG. It is guided by the above-mentioned guiding rod Z#'i, a protrusion provided on the inner wall of the cavity J, and facilitates the insertion of the element d into the element e.

To remove the element d inserted into the element e, push the protrusions // and / from the outside to bring them closer to each other. In other words, when the protrusions // and / are pushed closer together, the protrusions // and /, 2 can escape from the side holes, and since the sides of the protrusions // and / are tapered, , element d tries to escape along the slope, and eventually element d is separated from element e.

The fact that elements d and e are provided with an insertion portion at the other end means that
It is the same as that in Figure 1. In addition, the insertion portions of elements d and e include two slits 2/ and 2, and each slit 2/ and 2
2 are provided in parallel so as to approach each other and overlap each other, which is the same as in FIG. Furthermore, slit 2/
and 2.2, the wall surfaces 23 or 2G located on at least one side of at least seven gaps are inclined with respect to the plate surface p, and the wall surfaces 2J and 2J are located on at least one side of the plate surface p. It is also the same as that in FIG. 1 that the acute angle ridgeline portions 2j and 2g formed by intersecting each other are provided with concavities and convexities.

The connectors shown in Figures 1 to 3 are made by molding rather than by punching a plate. The material may be metal, but it is preferable to use fc molded material made of hard synthetic resin.

The connector C shown in FIG. 2 is used in the following manner. First, the synthetic resin packing band T is bent and passed through the gaps 2/ and 7.2. At this time, press T.
It is arranged so that it can be sharply bent at the acute angle edge portions 2.5 and 2g. The overlapping part of the band T is made to have a length several times the width of the band T, and is brought into direct contact with the surface of the article to be packaged. Similarly, connect the other end of band T to another slot 2/ and 2-? of connector C. Pass through the
Similarly, an overlapping portion is formed. In this way, as shown in FIG. 2, the article to be packaged is tightened with the mf band T.

At this time, if the band TK is loosened, the connecting tool af is lifted up and the band end T1 located above is moved in the direction of the arrow X to reduce the loosening.

In the connector of this invention, the band T is bent and passed through the narrow gaps 2/ and 2.2, the acute angles are sharply bent at the ridge lines 2j and 2g, and the band T is attached to the front and back surfaces of the band T. Since the concavo-convex pattern is in contact with the concavo-convex pattern attached to the ridgeline portions 2j and 2z, it is firmly fixed to the band T//i connector. When the folded portion of the band T is placed on top of that, the band TFi becomes difficult to slip against each other, so that the band T is more firmly fixed to the connector. Also,
With this connector, the band T and the connector can be connected by simply passing the band T through the gaps 2 and 2, so it can be easily connected at any location without the need for any special tools. can. Furthermore, since these fittings must be made by molding, they are different from metal fittings made by punching metal.
Since it does not damage the synthetic resin band, additional tightening is easy. The connector of the present invention thus provides several advantages.
