The invention draws on a magazine-like arrangement such fasteners, which the possible uses of such fasteners and their Attachment to the objects enlarged or improved.

Fasteners of the general type discussed here are disclosed in commonly assigned US Pat. Nos. 3 W-597 and 3,380,122 known. These known fastening elements each have a penetration section at one end section on, from which an elongated, thread-like section extends. Part of the other end section of the thread-like section is enlarged relative to the thickness or the diameter of the thread-like section educated. The penetration section is intended to be inserted through a hole in the object, i.e. to be threaded to which the fastener is to be connected, with this hole already present or can be made in the course of the fastening operation. The penetration section then remains on the other side of the article while the elongate portion extends through the hole. The enlarged section remains on the front of the article. The penetration section can be passed through the hole with its end first. After he has passed through this, he takes however, returns to its normal position which is substantially perpendicular to the elongate section and thereby preventing the fastening element from slipping out of the object in question again in one direction. Slipping out of the fastening element in the other direction is made possible by the enlarged section prevented.

As noted in the patents referenced above, these are known fasteners in general formed in a magazine-like arrangement, the one

409844/0689

BOEHMERT & BOEHIVRRT

Comprises a plurality of such fasteners. For example, a typical magazine contains 25 or more such fasteners *.

A fastening device or "gun" can be used to make the hole in the object, as described in applicant's US Pat. No. 3,103,666. By means of this device, a individual fastening element separated from the magazine-like arrangement and its penetration section is brought through the hole in the object and onto its other side.

Such fastening elements are used in particular in connection with the fastening device according to US Pat 3 103 666 to a considerable extent in the industry not only for the attachment of tags, labels and the like used on items to be sold in the trade, where the fasteners in particular also ensure that unscrupulous buyers followers, for example Price tags, swap and the price tag of a higher priced item with a price tag replace an item with a lower price, with only the lower price for the item is paid for. But they also serve to secure a group of Objects. The fastening elements in question here can in particular; if they are in connection be used with fasteners of the type described above, even by the relatively untrained Personnel can be handled extremely quickly, reducing the cost of labeling etc. or the costs for the mutual connection of several objects can be reduced considerably can. In fact they have been in many commercial fields

Such fasteners largely displaced and replaced all other fastening methods.

It should be noted, however, that certain difficulties are encountered when using the known fastening elements have revealed. For example, if it is desired to attach two objects, such as this in the In the case of matching pieces of a clothing set, it was due to the single penetration section required to pass the needle of the fastening device through both objects at the same time. However, the thickness of the relevant objects limits the application possibilities, namely when the combined thickness au is large in order to penetrate the needle and thus the subsequent attachment of a fastening element to allow. Furthermore, the pressure often to be applied calls for "inserting the needle into or through." Both objects often cause an undesirable stretching of the material of the objects, especially in the area out which immediately surround the penetration portion.

Although the known fasteners in a variety of applications for attaching labels, tags and the like have been extremely useful, they are not for a variety of other applications been. For example, they are not at the same time suitable as a hanging device for objects, which are to be arranged in a hanging position, such as this for example with scarves, handkerchiefs and this is often the case. In the same way, they are not suitable for use around loops like hanging eggs for garments or the like to form on a single item or for certain sewing processes as To serve as a substitute for sewing threads.

The invention is based on the object of the known

To improve arrangements and methods of the type described above while avoiding their disadvantages, and a such a magazine-like arrangement of fasteners to create the individual fasteners of which can be used in a simple manner to two or more To connect objects, in particular of a substantially combined thickness. The individual Fasteners can be attached with automated fasteners. Farther the individual fasteners should be connected to each other in such a way that they can be easily can be inserted into or attached to the same item or different items by only two successive actuations of the fastening device are required .. Furthermore, according to the task, the arrangement according to the invention should allow that their individual fasteners can be attached to objects in a manner that facilitates formation of loops of different lengths results. The arrangement according to the invention should continue to be inexpensive and be made with simple, effective automatic machine operations.

As a solution to this problem, the invention provides that one at each of the two end portions of the thread Fastening element each one when attaching the fastening element to at least one object Object penetrating penetration portion provided is; that a holding element is provided to which the fastening elements are connected via separable connecting webs which are located between the penetration sections and extend the retaining element; and that both ends of the fastening elements, with the shark ' testab are connected.

The presence of two penetration sections opens up a huge new field of application for this type of fastener. For example, the attachment of two objects does not take longer due to simultaneous Penetration of both objects by their combined thickness. Rather, it is now possible to have two objects to combine with each other by the first penetration portion through a first object and threading the second penetration portion through a second object. The two items are thereby effectively attached to one another without the difficulties that otherwise arise with larger combined thickness are present, and which are due the application of considerable pressure to penetrate this thickness.

Similarly, the penetration portions of a single fastener by a single Object, either through the same or through different openings. A Such an attachment method forms the thread-like section into a loop which can be used for a plurality of Applications, for example as a shirt or blouse hanger, as a hanger for coats, for decoration and fittings, as fastening hooks for objects that are displayed in a hanging position and the like. The penetration both ends of the fastener still allows their use for sewing purposes, for example textiles, in order to produce the long, loose stitches required when basting, for example to attach solid objects to fix exhibition objects made of cardboard or to take on similar tasks that self-evident for the practitioner.

Furthermore, the type of combination of the fastening

Advantages. Thus, each penetration section of the individual fastening elements is each integral with a rod-shaped connecting web via a separable connecting web
Holding element connected, the fastening elements being arranged in a row on this magazine rod
are. The penetration sections of each individual fastening element are fastened via adjacent, neck-shaped connecting webs. In this way it is achieved that a first actuation of the fastening device applies the first penetration section to an object, while the thread fastened to the first penetration section is still attached to the second
Penetration section remains connected, which in turn is still part of the integral arrangement. Only with the next actuation of the fastening device
the second penetration portion is separated from the assembly and completes the separation process and the attachment process, either the needle remains in the same place or is previously withdrawn and inserted in a different location. The arrangement according to the invention results in both a greater fastening speed and greater possibilities for automation for commercial applications and a minimization of the possibility of mutual entanglement. In addition, when the fastening elements are attached by means of the known fastening gun, it is possible to attach both penetration sections present at both ends of the fastening element by means of the gun.

to be able to be without a hole "of considerable size in the Object to produce.

The magazine-like arrangement of fasteners 8 comprises a plurality of interconnected fastening elements 10, each via a thin separable connecting web 20 are arranged along a holding or running rod 18, the following for the sake of simplicity is referred to as a "magazine stick".

Each of the transverse webs 12, 14 is in each case through a connecting web 20 formed or connected in one piece with the magazine rod 18, the transverse webs 12, 14 of each individual Fastening element 10 are arranged adjacent to the magazine rod 18 by means of the connecting webs 20. In the arrangement of fasteners obtained in this way the thread 16 of the individual fastening elements 10 is each designed in the form of a loop and extends between adjacent transverse webs 12, 14, which in turn by the adjacent, separable Connecting webs 20 are connected to the magazine rod 18. This construction is particularly good for suitable for use by means of a fastening device as described in US Pat. No. 3,103,666, there are two successive actuations of the device a fastener 10 can be quickly separated from the assembly in two steps and attached to one or more objects can attach.

The arrangement and its individual fastening elements 10 are preferably made in one piece from a thermoplastic Cast material such as nylon. In a typical formation of a single fastener 10, the suture 16 extends about 10 cm (4 inches) in length while the transverse webs 12, 14 extend about 1 cm (13/32 inch) are long and about 1.1 mm in diameter

(θ, 04-5 inches). It is understood, however, that these dimensions mentioned above can experience considerable deviations and from the relevant fastening element as well as the application in question.

For the use and puncture method of the arrangement of fastening elements 10 will be discussed with reference to U.S. Patent No. 3,103,666 and FIGS. 1-4 below. As can be clearly seen therefrom, the fastening device, also referred to below as a "pistol" for the sake of simplicity, has a fastening device 22 a needle 2A, with which the object to which a fastening element 10 is to be attached is to be penetrated. The needle 24 has on one Side a slot which is in communication with a slot 28 of the gun 22. The magazine can go into the pistol .22 are used in such a way that the magazine rod 18 penetrates through the pistol 22 with its penetrating the object Cross webs 12, 14 moved through, while the thread 16 each moves through a slot 30 that is present on the side of the gun 22 until the crosspiece 14 of the The respective fastening element 10 is aligned with the slotted needle 24-. Then a handle 22 the gun 22 is printed, a plunger comes with one end portion of the crosspiece 12 of the foremost fastening element 10 in engagement and acts on the transverse web 12 in such a way that it is relative to the associated Connecting web 20 is moved to him by the latter to separate. The ram then pushes the transverse web 12 out through the needle 24-, the corresponding thread 16 moved along the slots 26 and 28.

To attach a fastener 10 to an object 34 or to connect with several objects, the person who operates the pistol 22 pushes after insertion of a magazine into the gun 22, the needle 24 · through the

4/0689

BOEHMEKT & BOEHMERT

Object 34 so that the needle 24 has a hole in the object 34 trains. An actuation of the handle 32 then separates the transverse web 12 of the foremost fastening element 10 from the rest of the magazine and pushes it Part of the fastener 10 through, the needle 24 and finally out of the tip of the needle 24-. If the Crosspiece 12 moved to the back of the object 34- is, the thread 16 is drawn inward to the needle 24- and bent towards the front part of the crosspiece 12, so that a threading through the object 34- with the transverse web 12 takes place. It can therefore be seen that the size of the hole formed in the object 34- is not alone on the size of the needle 24, but also on the size of the effective cross-sectional area of the thread 16 depends. When the transverse web 12 leaves the needle 24-, it assumes a substantially perpendicular position to the surface of the Object 34- and in this way prevents the fastening element 10 from separating itself from the Item 34- triggers when pistol 22 is withdrawn, by pulling the needle 24- out of the object 34- again. At this point, the crosspiece 12 is on Object 34- attached, while the thread 16 is still attached to the crosspiece 14- which is still part of the one-piece magazine-like arrangement has remained, which is located in the pistol 22.

Then the needle 24- can be in the same opening of the object 34- and through another section of the object 34- or through a second Item 38 be struck. If the handle 32 is then actuated, the transverse web 14- becomes the foremost Fastening element 10 separated from the rest of the magazine-like arrangement and through the needle 24 as well as from the Tip of the needle 24 pushed. At this point the fastener is completely separated from the magazine.

If the crosspiece 14 leaves the needle 24, it is with the Thread 16 is threaded on article 38 and occupies a substantially perpendicular position to the surface of the object 38, thereby preventing the fastener 10 from separating itself from the object 38 to solve. The attached fastening element 10 now either connects two different objects 34, 38 with each other (see Fig. 6) or it is in one loop-shaped arrangement attached to a single object 34 (see Fig. 5).

Fig. 5 shows an arrangement in which the transverse webs 12 and 14 ^for through the same opening 36 of the object 3 l · have been implicated. It can be seen that for this purpose it is necessary to leave the needle 24 in the opening 36 and to actuate the pistol 22 a second time in the manner described when the transverse web 12 has been attached to the object 34. The second actuation then separates the transverse web 14, which is still attached to the magazine, and pushes it through the needle 24. When the transverse web 14 leaves the needle 24, it also assumes a substantially perpendicular position to the surface of the object 34. It can be seen that after the needle 24 has been removed from the object 34, the thread 16 has a loop-like shape which can be used for the most varied of applications which have been enumerated above.

6 shows the attachment of the transverse webs 12 and 14 two different objects 34 and 38. After attaching the transverse web 12 to the object as described above 34 · the needle 24 is moved back and into an object 38 inserted or stabbed through it. Subsequent actuation of the gun 22 disconnects Transverse web 14 and brings it in the manner described above on the object 38, where it is a substantially

right-angled position to the outside of the object 38 assumes. After removing the needle 24- are the objects 34 and 38 connected to one another by the thread 16.

Another possibility of attachment consists in attaching a fastening element, which is not shown 10 through two different holes in a single object. Here, after attaching the first transverse web 12 to the object in question in the above-described Way, the needle 24 · moved back and pushed through a second opening in the same object. A severing and attaching the second transverse web 14 results in either a loop-shaped attachment or a stitch attachment in the manner of a stapling, the type of attachment being dependent on the length of the fastening element and the Distance between the openings in question depends. You therefore have the option of long-loose stitches or staples to form that allow the fastening elements to be used for a stitching process, with a stitching like a Hem or the like temporarily quickly and effectively by attaching the fastening elements instead of pinning or sewing can be formed in the manner described at successive points along the stitching seam, wherein the distance between the attachment points is slightly less than or substantially equal to the length of the Thread 16 can be.

The fastening elements 10 according to the invention or the magazines can be applied to the same simple and proportionate cheap way to be manufactured, as is the case with comparable fasteners currently on are in the market. The present magazines, however, have the remarkable advantage that they contain fasteners, which have two transverse webs for the penetration of objects, wherein they are designed such that both crossbars quickly and consecutively from that

Separate magazine and attach to one or more objects are to be attached. The construction according to the invention of the magazine-like arrangement of fastening elements prevents In addition, mutual interlocking of the individual elongate fastening elements, since "both end sections the fastening elements are each fastened to the magazine rod and the fastening elements in this way and manner in proper orientation while they are Are part of the magazine. This orientation is also maintained during the application process, because due to the attachment of the first transverse web 12 the respective fastening element is securely held on the first object (z. B. 34) and on the other hand still on the magazine located in the pistol 22, while the necessary preparation for attaching the second Cross web 14 is hit.

As already indicated above, the fastening elements 10 can be used to connect two objects together. They can also be used to provide loop fasteners to items that are both "conventional" fasteners as well as assembly or connecting means can be used. The fastening elements according to the invention can also be used as a thread replacement in numerous sewing processes and the like.

The enlargements or thickenings 40, which connect the free end sections of adjacent threads 16, are provided to aid in the stretching of the threads 16 when they are made of nylon, they are their Increase tensile strength. These thickenings 40 serve to the two connected to the fastening element 10 Keep items 34 and 38 separate. If so desired is, the thickenings 40 can also be provided if they are not required for stretching the threads 16
