Description

The invention relates to a self-supporting position card serving as a carrier for a smart SIM card usable in one type of telecommunications and other devices and falls within the field of data storage media with at least one part thereof for recording and reading digital symbols.

BACKGROUND OF THE INVENTION

Nowadays, electronic and especially telecommunication devices using SIM cards are increasingly used. These electronic devices are fitted with small size SIM cards, where the chip surface is comparable to the SIM card carrier surface. However, there are also electronic devices fitted with such SIM cards in which the chip surface is substantially smaller than the carrier surface of the SIM card chip itself. Then, without further jig or adapter, it is not possible to use a chip SIM card from the first electronic device in the second electronic device. Thus, there has been a requirement that a chip SIM card of one carrier structure can also be used in an electronic device with a different SIM card carrier structure. Thus, a position card has been developed for this purpose. A position card according to European patent application EP 0 749 095 A2 is known from the prior art. It consists of a plastic flat support, in which a rectangular through hole with a bevelled corner is placed asymmetrically, with slits in the corners. A smart SIM card is inserted into this slot. It is fixed only by touching the peripheral edges of the rectangular hole. However, by frequently inserting and removing the smart SIM card from the position card, the edges of the smart SIM card wear out, and the smart SIM card is no longer firmly fixed and falls out of the position card. It is unpleasant for the user to handle it. The disadvantage of the prior art is that, after multiple removal and insertion of the smart SIM card from and into the position card, the protrusions on the edges of the smart SIM card that are formed after it has been removed from the production carrier are rapidly worn. In fact, these protrusions are the chip SIM card fixed in the rectangular through hole of the position card, but only for a short period of use.

SUMMARY OF THE INVENTION

The above-mentioned drawbacks are substantially eliminated by a self-supporting positioning card consisting of a plastic carrier and a symmetrically or asymmetrically positioned recess, according to the present invention, which is based on the recess being recessed and at least one of two adjacent or non-adjacent sides of the recessed recess being recessed. or continuous spring arrangements, the spring contact surfaces of which extend into the recessed recess.

Another essential feature of the present invention is the design of the spring arrangement. In one alternative embodiment, the recessed spring arrangements are formed by a set of recessed circular openings. The tangent of these holes parallel to the recessed edge is at or near the recessed edge. As a result, spring bridges in the form of a part of the ring are formed between the spring contact pads and the recessed circular holes.

In a second alternative embodiment, the recessed spring arrangements are formed by a wavy recess whose apexes are at or near the edge of the recessed recess. As a result, spring bridges in the form of a part of the ring are formed between the spring contact pads and the wavy recess.

In a third alternative embodiment, the recessed spring arrangements are formed by a convex recess whose apex is at or near the edge of the recessed recess. Thereby, a spring bridge in the form of a part of the ring is formed between the spring contact pad and the convex recess.

The present invention is particularly useful for self-supporting position cards with recessed rectangular or square-shaped recesses with one corner.

In order to achieve the desired fixation of the inserted SIM card, the depth of the recessed spring arrangement, which is at least equal to the depth of the recessed recess, is important.

By another design it is possible to achieve even more pronounced spring properties of the recessed spring arrangement. This is achieved in that the spring bridges are relieved from the other side of the plastic carrier by a shallow recess.

Finally, as an alternative, it is possible to achieve similar properties when at least one edge of the recessed recess is chamfered so that the lower dimension of the recess is larger than the upper.

The advantages of the self-supporting position card according to the present invention lie in particular in that they extend the possibilities of using a plurality of smart SIM cards adapted to the devices by serving as an adapter and a position device for other ways of fitting SIM cards in such devices.

Compared to similar prior art position cards which comprise a rectangular continuous recess, the substantial and obvious advantage of the self-supporting position card according to the present invention lies in the precise securing of the desired position and the reliable fixation of the installed SIM card. Accurate assurance of the required position of the SIM card and its reliable fixation in the self-supporting position card is also maintained by long-term use of the SIM card. The term long-term use of the SIM card in this case is to be understood as frequent and very often repeatedly inserting and removing the SIM card into and from a self-supporting positioning card in order to activate one of a plurality of devices adapted to a chip SIM card.

Finally, the advantage of the self-supporting position card is its easy and reliable handling with it and the chip SIM card. Advantageous features of the self-supporting position card are achieved by a special solution with a flexible arrangement without using for example a fixation tape. The spring arrangement does not comprise any additional elements, it is formed directly on the plastic card carrier. The spring bridges formed in the region of at least two edges of the recessed recess sufficiently press the chip SIM card against the opposite edges of the recessed recess and thus firmly fix the chip SIM card in the horizontal plane. The recessed bottom, in turn, fixes the smart SIM card in a vertical plane so that it cannot fall onto the other side of the self-supporting position card, as is possible with some types of prior art cards. In addition, the spring arrangement itself can be used for various chip card shapes. Rectangular types are used for telecommunication purposes. Square types are equally applicable. In principle, however, the given suspension system can also be applied to generally polygonal card types, although this is not used.

DETAILED DESCRIPTION OF THE INVENTION

Example 1

In this embodiment, FIG. 1 shows a self-supporting position card according to the invention with a recessed spring arrangement 2 formed by a set of circular openings 4. The self-supporting position card is made of a flat plastic carrier. It comprises an asymmetrically positioned recessed rectangular recess 1 with one bevelled corner 8. Two sides of the rectangular recessed recess 1 are provided with a recessed spring arrangement.

2. The recessed spring arrangement 2 is formed by a set of recessed circular openings 4 as shown in FIGS. 2 and 3. The centers of these openings are arranged in a single line so that their tangents T parallel to the edge H of the recessed recess 1 are in near this edge. In this case, the depth 10 of the recessed circular holes 4 of the recessed spring arrangement 2 is equal to the depth 9 of the recessed recess 1. The assembly The circular openings 4 consist of five circular openings 4 on the deeper side of the rectangular recess laz of three circular openings 4 on its shorter side.

In another variant arrangement, it is possible to vary the distance between the tangent T of the recessed circular holes 4 and the edge H of the recessed recess 1, as shown in Fig. 4. Thereby, the spring bridge 5 is advanced towards the recessed recess

1. Thus, for the spring contact pad 3 and the spring bridge 5 itself, other spring characteristics occur.

Example 2

The self-supporting position card according to this example is shown in Fig. 5 and represents a first alternative solution of the recessed spring arrangement 2, which are also located on two adjacent sides of the recessed recess 1. The recessed spring arrangement 2 is formed by the recessed bellows recess 6 as shown. 6 and 7. Its vertices V are at the edge level H of the recessed recess 1. Thus, at each apex V of the recessed bellows recess 6, spring bridges 5 are formed. Each spring bridge 5 has the shape of a part of the ring with vertical spring pads 2. in this case, the depth 10 of the recessed corrugated recess 6 is greater than the depth 9 of the recessed recess 1 but is less than the thickness 11 of the plastic carrier, as shown in Fig. 7. FIG. 8 shows a detail of one spring bridge 5 of a recessed spring arrangement 2.

Example 3

Fig. 9 shows a self-supporting position card according to the present invention in a second alternative embodiment. The recessed spring arrangement 2 is realized by a convex recess 7, one of which peak Z is at the level H of the recessed recess as shown in FIG. Thereby, a spring bridge 5 is formed between the apex Z and the spring plate 3. Also this alternative embodiment is the same depth 10 of the recessed recess with the depth 9 of the recessed recess 1 as shown in Fig. 11. Fig. 12 shows a detail of the spring bridge 5.

Example 4

In this example, a further alternative solution of the self-supporting position card is presented, in which, in order to improve the spring properties of the spring bridge 5, it is lightened from the other side of the plastic carrier by a shallow recess 12 as shown in FIG. 13 and 14. This makes the spring arrangement 2 continuous. The shallow recess 12 is of a depth such that it extends beyond the bottom of the recessed recess 1 and its diameter is greater than the diameter of the part of the spring bridge ring 5. This relief can advantageously be realized on circular openings

4. spring arrangement 2.

Example 5

Finally, there is another embodiment of the self-supporting position card shown in FIG. The principle is that the two edges H of the recessed recess 1 are chamfered so that the lower dimension of the recessed recess 1 is larger than its upper dimension. Thus, those sides of the recessed recess 1 are provided on which the spring arrangements 2 are located. Then, after insertion of the chip SIM card into the recessed recess 1 of the self-supporting position card, the resilient bridge 5 is tilted with its upper side towards e.g. into the circular opening 4 as shown in Fig. 16. Thereby, the chip SIM card is pressed by the spring pad 3 of the spring bridge 5 to the opposite side of the recessed recess 1 and is thus firmly fixed.

The function of the self-supporting position card according to the present invention is as follows. The chip SIM card used in one user's electronic device is removed from the device based on the user's needs and is inserted into the other electronic with a different size of the chip SIM card carrier by means of a self-supporting position card.

devices

The placement of the small-sized smart SIM card in the self-supporting position card is performed by orienting the smart SIM card with its bevelled corner with the bevelled corner 8 of the recessed recess of the 1 self-supporting position card. Thus oriented, it is then inserted into the recessed recess 1 at the same time with a slight pressure on the spring contact surfaces 2 of the spring bridges 5 at the two edges H of the recessed recess 1 to which the spring arrangements 2 extend. In the application of the slight pressure described above, the spring bridges 5 reversibly deform by their resilient contact pads 2 in contact with an embedded chip SIM card, which is so elastically clamped between the straight adjacent sides of the recessed recess 1 and its opposing adjacent sides. with spring arrangements 2.

The spring properties of the spring arrangement 2 depend on the thickness of the spring bridges 5, the depth 10 of the recessed spring arrangement 2 or the number of circular openings 4. The softness of the spring can be increased by a shallow relief 12 under the spring bridges 5.

By virtue of the fact that, in most embodiments, one side of the self-supporting position card is intact, any motif, such as an advertisement, can be displayed thereon by a suitable printing technique.

Industrial usability

The self-supporting position card according to the present invention is usable not only as a carrier of smart SIM cards for telecommunication devices, especially mobile phones, but also as a carrier of other smart cards for other electronic devices adapted for this purpose. In addition, the design of the spring arrangements can also be applied to other chip card shapes.
