Abstract: The invention relates to a device with a magnet arrangement having at least one permanent magnet, where the device displays a magnetically active, first contact surface for fixing it in place in a contact position on a magnetisable base. To extend the possible uses of the device, it is proposed that a signal-emitting functional device (6) having a functional element (6.1) be provided that can be actuated automatically to trigger the signal when the first contact surface (5) of the device (V) contacts the base (U), either by the dead weight of the device (V) or parts thereof and/or by the force of magnetic attraction acting between the first contact surface (5) and the base (U).

Abstract: A hinge is described for use along each side of a refrigerator or on furniture to permit safe opening of the door or lid from either side. The hinge is uncomplicated in design, and is comprised of only a few component parts. Each hinge includes a hinge rod forming a swivel axis for the door, said rod held in an axle take-up receiver. At least one and preferably two interlocks are located at or near the top and bottom of each hinge rod. The interlocks comprise a hinge pick-up axially aligned with the swivel axis of the hinge and a hinge element which becomes mechanically coupled to the pick-up when the door is opened in the other direction. Details of the embodiments of the hinge are disclosed. Preferably, magnetic means are used to keep the hinge rod engaged with the swivel axis and to form the airtight seal between the door and the cabinet.
