PCT No. PCT/CH97/00027 Sec. 371 Date Aug. 19, 1998 Sec. 102(e) Date Aug. 19, 1998 PCT Filed Jan. 29, 1997 PCT Pub. No. WO97/31170 PCT Pub. Date Aug. 28, 1997An apparatus and method for using a permanent magnet with a high coercive force and a permanent pole-reversible magnet with a low coercive force used in securing members in cooperation with wedging members. The apparatus also includes a release device, with a securing member inserted, and a combined control and feed device and a verification device, in the form of a till. The entire release device can therefore be, for example, directly linked to invoicing for a paid sum. The control and feed device controls and feeds the electromagnet coil of the magnetizing device. To release a securing member, the magnetizing device is activated, thereby reversing the poles of the permanent pole-reversible magnet. Both permanent magnets in the securing member subsequently repel, the wedge is released and the pin can be withdrawn from the locking section. |
