HAND BENDABLE METAL DISK WITH CORE AREA AND RING AREA

Abstract

The invention relates to a metal disk (2) comprising a circular core region (4) and a circular annular region (5), wherein the core region and the annular region are integrally formed and embossed, the core region is provided in the interior of the annular region, the annular region comprises a plurality of uniform segment portions (3), the core region is delimited from the annular region on an upper side of the metal disk by means of a peripheral closed peripheral groove (7) and each segment portion in the annular region is delimited from each adjacent fan-shaped segment portion by a radial groove (8) which ends at the closed peripheral groove, the direction of each radial groove extends on a straight line from a center point (M) of the metal disk to an outer edge of the annular region of the disk, and the segment portions can be manually bent around the peripheral groove relative to the core region in one direction.

Claims

1. Metal disk having a circular core region and a circular ring region, the core region and the ring region being formed and embossed in one piece, the core region being present inside the ring region, the ring region comprising a plurality of uniform segment sections, the core region of the ring region being on one top of the metal disk by means of a circumferential, closed circumferential groove and each segment section in the ring area is delimited from each adjacent fan-shaped segment section by a radial groove which ends at the closed circumferential groove, the direction of each radial groove on a straight line from a center point of the metal disk to an outer edge of the ring area of the disk runs, the segment sections being able to be bent manually in one direction relative to the core area around the circumferential groove.

2. Metal disk according to claim 1, wherein all elements of the metal disk can be broken off from one another manually along their grooves.

3. Metal disk according to claim 1 or 2, wherein the metal disk on the underside has a circumferential groove and radial grooves which correspond to the circumferential groove and the radial grooves of the top.

4. Metal disk according to one of the preceding claims, wherein the metal disk is made of a noble metal alloy.

5. Metal disk according to one of the preceding claims, wherein the metal disk is a coin or a medal.

6. Metal disk according to one of the preceding claims, wherein each element of the metal disk has an indication of the noble metal, the fine weight and the fineness.

7. Metal disk according to one of the preceding claims, wherein the relief results in a defined volume for each element defined laterally by grooves from its neighbors, in that predetermined relief projections are compensated for by relief depressions and vice versa.

8. Embossing stamp for producing a metal disk according to one of the preceding claims.

Description

[0019] The invention will be explained in more detail using the example of figures. It shows

[0020] FIG. 1 State of the art in the form of a daylight lamp with reflective shielding flaps in five perspective views;

[0021] FIG. 2 is a photograph of a metal disk according to the invention with grooves embossed on both sides

[0022] FIG. 3 is a drawing for a stamp template

[0023] FIG. 4 is a drawing for the top for a stamp template

[0024] The daylight lamp 1 shown in FIG. 1 in several perspectives is only used for illustration of the principle of bundled light reflection achievable with the metal disk according to the invention.

[0025] Bundling takes place in the case of the metal disk 2 (FIG. 2) by bending the six segment sections 3 in the direction of the viewer. It goes without saying that the groove flanks on the outer edge of the metal disk 2 abut one another from a certain bending angle and thus prevent further bending in this direction. Incidentally, the thickness of the metal disk shown is approximately 2.2 mm, so that the segment sections 3 and the core area 4 cannot be bent manually. The metal disk has a diameter of approximately 40 mm and weighs approximately 31 g (one ounce). The metal disk is made of fine silver.

[0026] The metal disk 2 shown in FIG. 1 in the form of a coin blank has a circular core area 4 with a quarter ounce fine weight. A circular ring area 5 of three-quarters of an ounce is formed around the core area 4, the core area 4 and the ring area 5 being embossed in one piece, that is to say from a piece of silver. The ring area 5 has six fan-shaped segment sections 3 of one-eighth ounce each (FIG. 4). The core area 4 is delimited from the ring area S on an upper side 6 of the metal disk 2 by means of a circumferential, closed circular circumferential groove 7. Each of the six segment sections 3 in the ring area 5 is further delimited from each adjacent segment section by a radial groove 8. Each radial groove 8 ends at the closed circumferential groove 7, the direction of each radial groove running on a straight line from a center point M of the metal disk to an outer edge of the ring region 5 of the metal disk, the segment sections 3 being manually bendable relative to the core region 4 around the circumferential groove 7 in one direction. In the case of repeated bending back and forth, breaking can be achieved and the metal disk 2 can be broken down into seven individual parts.

[0027] FIG. 3 shows an underside of a metal disk with exemplary information on the fine weight, the fineness and the material of the metal disk in the form of a medal. FIG. 4 shows the top of this medal. Both sides are created by the medalist Erich Ott.
