Fastener

The invention relates to a fastening element with a thread on which "along its length at least a head enlarged in the transverse direction is present, and at one end portion of which a body piece is arranged is, which has a plug-in base forming through opening through which the Thread is to be passed through, the head is to be kept in engagement with the plug-in base.

The invention also relates to an arrangement of several fastening elements of the above type.

Many types of commercial activity require a tag or label on one to attach items to be sold. This is especially the case with retail sales, with the article for viewing and "selection issued by the customer be, and where numerous refer to the article

409834/0316

related information, particularly the price to which the item must be attached. In many cases, especially in the case of large and heavy articles or articles made of a material which cannot be penetrated, tags or labels are attached to such articles by means of a wire or a string attached. The work required to get the wire or string through a hole in the pendant or label through and then attach the combination to the article by tying or otherwise Attaching the ends of the wire or string to the article is very time consuming and therefore represents a notable cost factor. In addition, in particular self-service processes, in which products of various types of Hand picked up by the customer and then taken to a central location for these items is paid, the very serious problem of confusing tags or labels with yourself. Because an unscrupulous customer often takes a tag or a label from an item with a low price Price, in order to then attach it to a more expensive article and the wrongly labeled in this way Item then presented to the cashier, leaving only the incorrect low price will be paid.

There is therefore a great need in the commercial industry for an arrangement or a system which not just the respective application of the applicable label baw. Trailer to the various too objects to be sold, but which one

409834/0316

it is also impossible, or at least difficult makes for an unscrupulous customer to swap the tags or labels. Such arrangements and Training courses have already become known.

Such a design is shown in U.S. Patent 3,402,435 issued September 24, 1968 to Merser called "Tag Attaching or Bundle Fastening Device", which is a Reissue US patent 27 357 on May 9, 1972 to the assignee of the present Patent application has been reissued. In that patent is a fastener discloses which is suitable for attachment to a trailer to a trailer-fastening element combination to build. The fastening element has a thread and a base for receiving the thread on, the thread being suitable due to an enlarged end portion, through a suitable portion of the article to be labeled, provided with the tag and then in the base of the Fastening means to be guided in order to be held there reliably and permanently in position. The specific design of the thread and the base can be of various types. Another shape is Merser's "Connector For Holding Articles Together" issued August 26, 1969; This patent is shown on June 20, 1972 as reissue US Patent 27,391 assigned to the assignee of the present Patent application has been reissued.

Other shapes and designs of fasteners are also known.

409834/031 6

A feature of the fasteners according to the two aforementioned patents is that the head of the thread is practically not detached from the base can be, if it has been used in these. Accordingly, the only way to release the tag-fastener combination is of the article to which the combination is attached, therein, the portion of thread break through the fastener. This of course prevents an installed Label or a tag attached in this way is used in connection with another ^ incorrect sales item.

However, the fasteners described in those patents suffer from several disadvantages. So can the known fasteners only on objects which have pre-existing holes such as eyes, buttonholes or the like. One Penetration of clothing, towels and the like is difficult and due to the large size of the Hole, which results when inserting or threading the enlarged end that the introduction of the Allowing thread into the base, undesirable. Such a requirement limits the field of application such fasteners significantly by reducing their application to numerous articles, clothing and the like which do not have such openings. An even more significant disadvantage consists in the fact that these fasteners must be attached by hand, i.e. the Thread must be hand through the article and the socket

409834/0316

_ 5 -

be threaded. Although these fastening elements are completely different from wire or cord connections represent a considerable improvement, are the costs and costs resulting from the manual application Time factors still represent a considerable reduction in their efficiency. Another related one The disadvantage is that the construction of these known fasteners does not follow any arrangement Kind of a magazine consisting of a plurality of fasteners allowed with a Fastening gun, such as one in U.S. patent issued September 17, 1963, could be used 3 103 666 (Bone) is described, in this way quickly and effectively the fastening elements to be able to attach to a considerable variety of objects. Furthermore, the known Fastening elements do not have anchoring means which allow the fastening elements, for example to be attached to a perforated plate for holding purposes, for example. However, this represents at least then a useful feature when using the fasteners as a means of bundling wire or the like can be used.

The invention is based on the object of avoiding the fastening means of the type described above to improve their disadvantages, and to create such a fastening element, which with mechanical means is to be attached to suitable objects, webei the construction of the individual fastening elements should be such that they are to be connected to a magazine or an arrangement of several fasteners, which in a simple manner

409834/0316

To be used in conjunction with an automatic fastening device. A new one is supposed to be Fastening element can be created which does not rely on a preformed opening in the object to which it is to be attached. Finally, the fastener should have an anchoring be provided with means that allow it to be connected to perforated plates or other holding devices, despite these considerable advantages over the known fastening elements manufacturing and arrangement should be possible through simple and cheap machine operations.

As a solution to this problem is provided according to the invention that at the other end portion of the thread is provided which extends essentially transversely to the longitudinal axis of the thread, which in im substantially parallel alignment to the thread through the passage opening of the fuselage piece is.

The fastening element according to the invention is therefore as in the known constructions with one here referred to as the fuselage, with a plug-in or Equipped through opening provided body from which the thread extends. The thread has generally not just one but a plurality of heads extending along its length, wherein the heads are designed so that they are received by the base of the fuselage section or by this can be moved through. The base is in each case with the or one of the distributed over the length of the thread arranged heads so engaged that he

409834/0316

reliably holds the thread back in the socket once the head in question has been placed in it is. The entire fastening element is preferably made of a suitable plastic, for example can be processed in considerable numbers by casting at relatively low cost.

The present fastening element therefore differs essentially from known constructions by a normally transversely extending element, which is referred to here as a crosspiece, and which is attached to the end portion of the suture opposite the body piece. The presence this pin-shaped crosspiece allows the fastening element according to the invention in areas of application To find uses on which the known fasteners could not be used, because it can be made in a magazine-like arrangement with mechanical fasteners can be processed and used in objects that do not already have have pre-existing openings. The presence of the - essentially transverse to the longitudinal axis of the thread extending pin-shaped crosspiece allows the individual fastener to be integral with a Holding rod connected and to be lined up to several along the holding rod, the cross pieces with are connected to the holding rod via a fracture pin. The fasteners are in this way resulting magazine-shaped arrangement can be efficiently and quickly by means of an automatic fastening device attached to objects, where

Λ09834 / 03 1 6

such a fastening device each .ein Fastening element separates from the magazine-like arrangement, the crosspiece and the thread through the plug-in base of the fuselage piece and brings the cross piece through the desired object to in this way to keep the object on the thread or the thread in the object.

As noted above, one such fastener is in U.S. Patent '666 (Bone). Accordingly, such a device has feeding or advancing means to a to process essentially consisting of fastening elements magazine in such a way that the cross pieces adjacent fasteners sequentially brought into alignment with the base of a hollow hub will. A fastening element arranged in this way is then replaced by the magazine-like one at its fracture pin Separated arrangement. A piston-like component then drives the crosspiece of the fastener through the needle, the thread laterally protrudes from a slot. If "the needle before has been passed through an object, the crosspiece is therefore also passed through this. The thin thread is bent onto the rear portion of the crosspiece when it hits the item happened. The needle is then withdrawn and the pin-shaped crosspiece is then effective to hold the object threaded on the thread.

The fastening element according to the invention contrasts

£ 09834/0316

over the known constructions also thereby a Improvement is that it has an anchoring. The anchoring is preferably in the manner of a slotted one Fingers formed and has barb-shaped lugs that extend across the finger extend outwardly, with the finger extending laterally from the base body and in a suitable manner Way is designed to be passed through an opening in a plate or other holding part be and with this bzxir. this engaged to be able to. In this way, the fastening element as a whole can be anchored to such a holding means are and therefore ensures an assembly or. Holding option, which is particularly useful when when the fasteners are to be used for bundling purposes.

The invention and preferred embodiments of the invention are further explained below using exemplary embodiments with reference to a drawing. It shows:

Figures 1 and 2 show a preferred embodiment of a fastening element according to the invention. As shown there, "the fastener; 10 an elongated thread 12, a normally transverse and therefore readjusting piece as a cross "designated pin-shaped part 14 at one end of the Thread 12, hereinafter referred to as a body piece " Part 16 at the other end of the thread 12 and a number of heads 18 which are spaced apart are arranged along the length of the thread 12.

The crosspiece 14 is shown as a relatively thin cylinder, which is at its center on the thread 12 is attached and extends substantially at right angles to the thread 12 so that it is with the thread 12 forms a substantially T-shaped arrangement. The cross piece 14 shown in Figure 1 has a circular Cross-section .. However, numerous other shapes are also suitable for this. At a The cross-piece 14 is operated in the manner described in greater detail below inserted into an object or passed through it along its axial direction, the Object adjacent to the cross piece 14 is threaded onto the thread 12 and the cross piece 14 thereafter serves to hold the object on the thread 12. Accordingly, the crosspiece 14 must be a sufficient maximum Have length-to-width ratio in order to effectively prevent the object again from the thread 12 slides down or that the thread slides out of the object. In addition, the crosspiece 14 must be sufficient small effective cross-section on v / iron to

409834/0316

to enable it to pass through the object, i.e. to be threaded, without a larger or considerable hole is generated in this, and it must also be possible, the cross piece through the base.

The part referred to here as the fuselage piece 16, which is located at the end of the thread 12 opposite the crosspiece 14, has a through opening 20, which forms the plug-in base 22. The base 22 is preferably circular in cross section and the Heads 18 are conical. The heads 18 are slightly larger than those leading through the base 22 Through-opening 20 so that they sit on the mouth of the base 22, as. this is shown in FIG and must be forced through the base 22. This will be based on the existing Resilience compresses the heads 18 slightly as the base 22 expands. If so desired is, the sides of the base 22 can be slotted, as indicated at 23, in order to thus the Possibility of temporarily spreading the base 22 when the heads 18 through it be squeezed through. Accordingly, when the desired number of heads 18 has passed through the base 22 and thereby forming a loop of the thread 12 of the desired circumferential length, the thread 12 cannot reverse be withdrawn from the base 22, as can be seen due to the conical shape of the heads 18 and the engagement the back of one of the heads 18 with the tip of the base 22 results.

409834/0316

As shown in Figure 1, there are a plurality of fasteners 10 together, i.e. in one piece to form an arrangement of several fastening elements formed, wherein the individual fastening elements are fastened with pins 26 on a holding rod 24. Accordingly, the transversely oriented crosspiece 14 of each fastener 10 is by means of a fracture pin 26 fastened to the holding rod 24, the pin 26 in each case when the fastening element is attached 10 can be separated in a simple manner. In particular, this construction is extremely good suitable for use together with a fastening device such as those under the designation "Bone '666" is known as the fastener disconnected in a simple manner by means of this device on the basis of a single actuation, the thread is inserted, the desired number of heads passed through the base and the crosspiece as well as the thread can be passed through the object.

The fasteners are preferably made of a thermoplastic material such as nylon in one Shaped in the manner described in detail in U.S. Patent 3,444,597 (Bone). This US patent issued on May 20, 1969 and assigned to the assignee of the present application. In a typical embodiment, the thread 12 extends approximately for a length of 10 cm (4 inches), the length of the crosspiece 14 being approximately 1 cm (13/32 inch) and its diameter being approximately 1.15 mm (0.045 inch).

409834/0316

It should be noted, however, that these dimensions can be varied considerably and from the respective fastening element and its special Application depend.

The type of use and the mode of operation of the fastening elements described here results from the comments below. The arrangement according to Figure 1 is in an automatic "device for Tag fasteners of the type introduced in the aforesaid patent by Bone and the crosspieces 14 are sequentially aligned with the base of the hollow needle. The needle pierces the object O and is then passed through the base 22. Should also If a label or tag T is attached, the needle will be inserted through the socket 22 passed through the label or the hanger. When the fastening device is activated, the fastening element 10, which has been brought into position in this way, is separated from the arrangement at its pin 26 and the cross piece 14- is driven by a piston through the needle and accordingly through the object 0 and the base 22 passed through, wherein the thread 12 extends laterally out of the axially extending slot of the needle. When the cross piece 14 extends beyond article 0 and base 22, thread 12 is drawn inwardly towards the needle and accordingly essentially bent by 90 to the rear part of the crosspiece 14-. It can be seen that not only the size of the hole produced in this way in the object, which is generally made of fabric

409834/0316

on the size of the needle but also on the effective cross-section size of the thread 12 and its Flexibility depends. When the crosspiece 14 leaves the needle it jumps into the T-shape with respect to the Thread 12 back. The needle is then withdrawn from article O and socket 12 and left behind the object O with an effectively fastened thread 12. The loop that is made when inserting the Thread 12 is formed by the base 22, can have any circumferential length and depends on the Number of heads 18, which have been passed through the base 22. The loop serves accordingly to hold an article or a tag on it or it serves as a means of attachment for mutual Attachment of objects.

In an embodiment of the invention, the fastening element 10 can be provided with an anchor 28, to attach the fastener 10 to any conventional perforated support to be able to. The anchorage 28 is formed in one piece with the fuselage piece 16. She has a finger-shaped Part 30, which extends laterally from the base 22 to the outside. The finger 30 has a slotted portion 32 and tabs 34 and 36 extending from the finger 30 in FIG extend its plane. As shown in Figure 3, the finger 30 has a perforated plate 38 or another carrier or holding means in engagement by being passed through the opening or perforation is, with the barbs 37? 36 the edges touch the opening or perforation and a

409834/0316

Prevent finger 30 from being removed. The width of the opening in the plate 38 is expediently narrower than the distance between the outer extreme points of the lugs ⁷ J \ and 36 »In this way, due to the flexibility of the finger 30 and its inward flexibility due to the slot 32, the lugs 3 ^ »36 can be compressed for insertion into or through the smaller opening and then expand again to their normal dimensions when they are free of the perforation or opening again. The fastening element 10 is securely fastened to the plate 38 in this way, the lugs 34-, 36 serving as stops when they come into contact with the corresponding outside of the plate 38, preventing the fastening element 10 from becoming detached from the plate 38 . Correspondingly, the base 22 limits the movement of the finger 30 through the opening by acting as a stop when it comes to rest against the corresponding front side of the plate 38.

FIG. 4 shows the application of the invention Fastening element for binding and supporting wire bundles. In operation, the thread 12 is around wire strands W passed around and then through the base by any suitable means already described above 22 led. The thread 12 is then pulled tightly around the wire strands W and through the base 22 until none further heads 18 are to be pulled more through the base 22. The loop formed in this way binds the wires W together as a unit, the fact that it is necessary for the thread 12 due to the

09834/0316

conical shape of the heads 18 and the engagement of the Top of the base 22 with the back of the last head 18 is impossible to be withdrawn from the base 22 to become any untying of the tied bundle prevented. The length of the thread 12 that has been pulled through the base 22 can be traced afterwards be separated from the arrangement. As has already been stated above, anchorages 28 make it possible attaching or holding the bound bundle by holding the anchors 28 with a perforated retaining plate 38 are engaged in the manner described to secure the bundle in a fixed position on the Hold plate 38. Depending on the particular type of bundling system, the attachment to the plate 38 either before or after the binding operation.

Due to the construction according to the present invention, fasteners can be made with the same Possibilities and in the same relatively cheap way as this one is the case with comparable fasteners on the market. The present fastener however, has the particular advantage that there is a substantially transversely extending, has a web referred to above as a crosspiece, which allows it to be guided into or through objects v / grounds that do not have preformed openings, with the new fastener in arrays. To produce magazines that have a plurality of fasteners and in this way allow their quick and effective attachment by means of mechanical devices. The construction

409834/0316

also includes anchoring means which allow attachment of such fastening means to perforated retaining means "or carriers.

As already mentioned above, the fastening means according to the invention can be used for to attach labels, tags or the like to articles, to connect two or more articles to one another connect in order to bundle a number of articles or to simultaneously several of these mentioned punctures perform.

It can be seen that numerous deviations from the design described are possible without the Is left within the scope of the invention.
