In the second pivoted position P2, the laboratory bench 20 protrudes at a right angle from the cupboard 10.

(25) The cupboard 10 in each case has an internal cupboard space (see in this respect reference sign 11 in FIGS. 3b, 6b, 9b) which is enclosed by a front side 12, a rear side 13, an upper side 14, side walls 15, 16 and a base side 17. It is seen by way of the overall height of the cupboard 10 in relation to the working chairs 70, 71, 72, 73, 74, 75 and working tables 50, 51, 52, 53, 54 that said cupboard is designed in each case as a side board. The height is approximately 1.1 meters. Alternatively, the cupboard may also be designed as a high board, for example with a height of over 2 meters.

(26) The laboratory bench 20 is mounted on the cupboard so as to be pivotable via an axis of rotation A (concealed by structures on the laboratory bench 20 in FIGS. 1 and 3) in such a manner that it can be positioned in the cupboard space in a first pivoted position about the axis of rotation A, and is arranged outside the cupboard space 11 in the second shown pivoted position P2 about the axis of rotation A. For this purpose, the axis of rotation A is oriented geodetically vertically.

(27) It is seen that the laboratory bench 20 has a supporting means 21, namely rollers 22, 23, for supporting on the base (floor) B. In the second pivoted position P2, the rollers 22, 23 are arranged outside the cupboard space 11 because they are arranged at the end of the laboratory bench 20 that is opposite the axis of rotation A.

(28) It is furthermore seen that the cupboard 10 has a cupboard door 60. The cupboard door 60 consists of two door elements 61, 62 (the first door element 61 is concealed in FIGS. 1, 5 and 8, but is indicated in FIGS. 2, 3a, 3b, 4b, 4c, 6a, 6b, 7b, 7c, 9a, 9b, 10b, 10c). The first door element 61 is fastened to the second door element 61 via an inwardly opening hinge with a vertical axis of rotation. The second door element 62 in turn is fastened to the first side wall 15 via an outwardly opening hinge S with a vertical axis of rotation. It is clear that the axis of rotation A of the laboratory bench 20 and the hinge S of the cupboard door 60 are arranged on opposite sides on the side walls 15, 16 of the cupboard 10.

(29) In the second shown pivoted position P2 of the laboratory bench 20, the cupboard door 60 closes the cupboard 10 with the second door element 62 except for the laboratory bench 20. The remaining region of the front side 12 of the cupboard is closed by the laboratory bench 20. For this purpose, the laboratory bench 20 has an upwardly protruding panel 26. The panel 26 preferably ends, as shown, at the same height as the cupboard door 60.

(30) A storage space 24 which is closable with doors is provided within the laboratory bench 20. The higher structures 32, 33, 34, 36, 37, 38 on the laboratory bench 20, in particular those which protrude over the height of the cupboard, are designed in such a manner that they are designed such that they can be folded over flat in order to store the laboratory bench 20 in the cupboard 10.

(31) In FIG. 1, the laboratory bench 20 has a working surface 30, power connections 31, a water connection with a water tap 32, a basin 34 with a liquid outlet 33, a gas connection with a gas tap 35, and a working lamp 36.

(32) The laboratory bench 20 has a rim 25, against which a working table 50 and a working chair 70 are placed in the second pivoted position P2 shown. A laboratory device 1 fitted in such a manner is suitable, for example, as a simple demonstration laboratory surface for a teacher.

(33) According to FIG. 5, the laboratory bench 20 has a working surface 30, power connections 31, a water connection with a water tap 32, a basin 34 with a liquid outlet 33, a gas connection with a gas tap 35, a camera 37 and network connections 39.

(34) In the second pivoted position P2 shown, six working tables 50, 51, 52, 53, 54 and six working chairs 70, 71, 72, 73, 74, 75 are placed in a rectangular table formation against a rim 25 of the laboratory bench 20. A laboratory device 1 equipped in such a manner is suitable, for example, as a group work station for up to six learners.

(35) FIG. 8 shows a laboratory bench 20 which has a working surface 30, power connections 31, a water connection with a water tap 32, a basin 34 with a liquid outlet 33, a gas connection with a gas tap 35, a camera 37, a screen 38 and network connections 39.
