The invention relates to a system unit for a computer, said system unit being provided on one wall with a swivel-mounted front flap and with a cover which is locked when the front flap is closed and unlocked when the front flap is open.
A system unit of the aforesaid kind is known from the Siemens ST PC Catalog, Edition 2006, pages 2/4 and 2/5. An operator input unit, e.g. an operator input unit in the form of a keyboard and/or a mouse, as well as at least one image reproducing device and other hardware units can be connected to said system unit in the form of a rack PC. Moreover, the rack PC is provided with further hardware means that are suitable for operation of the computer, with interfaces as well as floppy disk and/or hard disk drives being disposed in a recess which can be closed by means of a swivel-mounted front flap. Additionally provided on the front side is a swivel-mounted fan cover which is locked when the front flap is closed and unlocked when the front flap is open. For that purpose a swivel-mounted edge region of the front flap is embodied in such a way that it completely covers an edge region of the fan cover when the front flap is closed and consequently the fan cover is not locked.
An object of the present invention is to provide a system unit of the type cited in the introduction by means of which locking the cover is simplified.
This object is achieved in that a rotatably mounted lock is provided, into the bearing of which engages a hinge pin by means of which the front flap is swivelably mounted, and in that when the front flap is closed it presses on a driver of the lock, as a result of which the lock rotates such that a catch of the lock locks the cover.
In one embodiment of the invention the hinge pin and the lock are disposed in a frame, wherein the catch and the driver each project from a cutout in the frame. As a result of this arrangement no additional space is required for installing the lock.
In a further embodiment of the invention the lock has a return spring. When the front flap is opened, said spring rotates the lock in such a way that the cover is unlocked automatically.
A further advantageous embodiment of the invention will emerge from the further dependent claims.
The invention, its embodiments and advantages are explained in more detail below with reference to the drawing, in which an exemplary embodiment of the invention is illustrated.

In the present exemplary embodiment the floppy disk or hard disk drives 2, 3 and a USB stick 4 are disposed in a recess 5 which can be covered by means of a swivel-mounted front flap 6 and closed by means of a key 7 having a suitable locking mechanism. On the front side the system unit 1 is additionally provided with a fan cover 8 whose first frame region 9 hooks into the system unit 1 and whose second frame region 10 latches by means of a snap fit into the system unit 1.
In order to prevent the possibility of the snap-in connection being released with the front flap 6 closed and the fan cover 8 being removed from the system unit 1, there is disposed in a frame 11 of the system unit 1 a rotatable lock 12 into the bearing 13 (
