Definitions

  • the invention relates to a securing nail for connecting and / or closing a merchandise security label on a product, in particular a textile, comprising a pin with a shaft for engaging in the pin holder of a goods security label and with a pin head and comprising a plastic head enclosing the pin head.
  • Goods security labels are used to secure goods against theft.
  • Such goods security labels are attached to the goods and, depending on the design of the goods security system, have, for example, a transponder. If such a transponder is passed through a transceiver device typically arranged in the area of the entrance of a department store as a control device, an alarm signal is generated. Goods from which the goods security label has been removed in the course of payment of the same, can be readily brought out by the transceiver. Therefore, the goods security label mainly serve to detect thefts. Depending on the conception of such a merchandise security label, these can also be used to record a flow of goods.
  • Such a merchandise security label must, in order to fulfill the function of an anti-theft protection, be connected to the merchandise in a manner such that, on the one hand, the merchandise can not be damaged by it and, on the other hand, can not readily be removed therefrom.
  • Such goods security labels usually have a plastic body in which encapsulated the required electronics or the required components or components are included.
  • Such merchandise security labels can be constructed in two parts, wherein each part of the label is located on each side of the goods. The two parts of such a goods security label can be connected to each other by a film hinge. In addition to these two-part merchandise security labels, one-piece security etiquettes are also used.
  • Retaining nails are used to hold together the two individual parts of a two-part merchandise security label and to attach a one-piece merchandise security label to the merchandise.
  • a safety nail consists of a metal pin, which in turn has a shaft.
  • the shaft of the pin is used to engage in a corresponding pin receptacle of the merchandise in which the shaft is typically held locked.
  • a clip may be provided, which can be brought into its unlocked position, for example by means of a sufficiently strong magnet, so that then the safety nail from the goods security label to release the merchandise security label can be pulled out of the pin receptacle of the goods.
  • the shaft of the safety nail may have circumferential grooves, in which engages the example formed as a spring clip closure element for locking the safety nail in the pin accommodating the goods security label.
  • the metal pin of the safety nail has a head. Connected to the head of the pin is a contact surface of the safety nail on the goods magnifying plastic head.
  • the plastic head of such a safety nail may have different shapes. Widely used are domed plastic heads.
  • To connect the pin head with the plastic head has according to a previously known embodiment of the plastic head on a recessed pin receptacle in which the metal pin is hammered, so that the pin head sunk within the plastic head is arranged and the shaft protrudes from the bottom of the pin head. In order to meet the desired pull-out forces of the pin head from the plastic head, sufficient plastic material must be present between the underside of the pin head and the contact surface of the plastic head.
  • plastic head has a certain minimum height.
  • the mouth of the pin holder is sometimes closed by a cap.
  • plastic heads are made with a uniform material thickness, especially after the molding injection molding of the plastic head cools evenly and, without having to take any additional measures, a sufficient surface quality is given requirements.
  • a two-part design of such a plastic head it is attached to the safety pin a disc on the outer edge of which the actual head forming plastic body is clipped as a cap.
  • Retail security labels are used to a great extent for securing textiles.
  • plastic heads of the above-described safety nails they must have a certain height, as already described in one-piece safety nails.
  • a certain height of the plastic head is necessary to make a proper connection of the plastic cap with the disc.
  • safety nails can not be used with plastic heads due to their height, as they impress due to their relatively high height for these concerns in the textile and thus cause bumps.
  • Another disadvantage of the known safety nails is that they do not have a smooth, continuous underside due to the necessity of having constant wall thicknesses, but rather radial ribs. When subjected to pressure, these too are pressed into the textile.
  • the object of the invention is therefore to propose a securing nail which is improved, in particular, for use in attaching consumer protection labels to textiles.
  • the plastic head is connected by injection molding or other similar plastic molding process to the pin including the Stiftkopfveriererungs institutes total or at least to the extent of his or her the surface of the underside of the pin head magnifying sections.
  • This safety nail has a pin head enlargement element. This serves to increase the underside of the pin head, which typically only slightly protrudes over the shaft, toward the shaft of the pin.
  • the Stiftkopfveriererungselement serves to provide an enlarged attack surface for the molded around the pin head or the Stiftkopfverieselement by means of an injection molding plastic head. Due to the provided by the pin head enlargement, with respect to the underside of the pin head much larger area, the thickness of the overmoulded plastic head in the direction of the shaft of the pin need not be particularly large to hold the required extraction forces of the pin from the plastic head stand. This allows the formation of a plastic head, which is kept very flat with respect to its height.
  • the provision of the arranged within the plastic head pin head enlargement element has, at the same time with a relatively flat configuration of the plastic head, the fact that the thickness of the pin head or his Stiftkopfveriererungselement enclosing plastic shell over the cross-sectional area of the plastic head seen can be made relatively homogeneous and thereby a uniform cooling of the plastic head is guaranteed after the process of injection molding to achieve high quality plastic head surfaces.
  • the pin head enlarging element can be designed as a disk in the manner of a washer.
  • the pin head overhangs the opening of the disc, which is penetrated by the shaft.
  • the Stiftkopfveriererungselement bounded form-fitting manner alone in the extension direction of the pin head of the pen.
  • the pin head enlarging element is designed as a blank, whereby the pin head is completely enclosed by the blank.
  • the blank not only enlarges the underside of the pin head but also its upper side. ßert.
  • the top of the pin head is supported on the inner wall of the blank.
  • Such a blank is typically made of metal, preferably steel. In such an embodiment, there is no danger that upon insertion of the shaft into the pin holder of a security label when a higher force is applied, the pin head is pushed out of the plastic head.
  • the pin head enlarging element encloses the pin head and thereby forms a cavity with respect to the overmolded plastic head
  • the pin head can be moved within such a pin head securing element by a certain amount in an articulated manner and / or in the axial direction of the shank is.
  • the possibility of tilting the pin relative to the plastic head with such a safety nail allows to attach a goods security label also on goods in which the surfaces on which the underside of the plastic head on the one hand and the investment side of the merchandise security label on the other hand not parallel to each other.
  • such a pin head enlarging element simultaneously provides a bearing sleeve for an articulation of the pin head, which is articulated in the manner of a articulated joint, to the plastic head.
  • the pin head enlarging element is preferably formed tapered on its side facing the shaft of the pin to the lateral surface thereof. This allows a head to be encapsulated to create the plastic head itself provided seal so that in the course of the injection molding process no plastic flows out of the outer surface of the shaft outside of the plastic head to be created.
  • the pin is held in a plastic injection molding tool in a corresponding shank receptacle, the mouth of which is sealed into the injection molding cavity of the tool by the tapered, abutting the mouth of the shank receiving end of the Stiftkopfverieresettis.
  • the plastic head is created by molding the Stiftkopfveriererungsele- mentes and this process over the underside of the pin head many times larger underside of the pin head - magnifying element is plastic covered, this allows the formation of a smooth over the entire bottom, flat design of the Plastic head. Due to the larger contact surface of such a safety nail with the bottom of his plastic head on, for example, a textile is a formation of prints of the safety nail on the goods, especially a textile minimized. Due to the size of the provided contact surface, it is readily possible to arrange the sprue on the underside of the plastic head. This is preferably deepened.
  • the invention is described below with reference to an embodiment with reference to the accompanying figure.
  • the securing nail 1 comprises in the illustrated embodiment, a pin 2 made of stainless steel.
  • the pin 2 has a shaft 3, which tapers in the direction of the foot of the pin 2 in a tip 4.
  • the tip 4 is rounded at its free end 5.
  • a pin head 6 Formed on the shaft 3 is a pin head 6.
  • a stainless steel pin 2 as provided in the illustrated embodiment, this may also be a steel pin with a surface treatment, for example applied by way of a galvanic coating act.
