Mobile media supply device

A mobile media supply device (1) for the accessible selective supply of at least one workstation, in particular a school or laboratory workstation, with at least one technical medium, including:

• (i) a body (10) mounted on wheels (18), which defines a cavity (11), in which at least one media store (40, 60) for a technical medium is received,
• (ii) at least one media withdrawal connection (21, 22), which is connected to the media store (40, 60),
• (iii) a media blocking device (72, 74), which is arranged between the media store (40, 60) and the media withdrawal connection (21, 22) and in a first state enables the withdrawal of the technical medium from the media withdrawal connection (21, 22) and in a second state prevents the withdrawal of the technical medium from the media withdrawal connection (21, 22),
• (iv) a mobility blocking device (120) for blocking the mobility of the media supply device (1), and
• (v) a control device (100), which is arranged to change the state of the media blocking device (72, 74) and further to block the mobility of media supply device (1) by means of the mobility blocking device (120),
• characterised in that at least one release device (90a, 90b, 90c) to be actuated by a person is provided, which is connected to the control device (100), and in that, when the release device (90a, 90b, 90c) is actuated, the control device (100) is arranged such that the control device (100) is prompted to block the mobility of the media supply device (1) by means of the mobility blocking device (120) depending on the state of the media blocking device (72, 74) automatically and without the aid of the person.
