It is a well-known drawback that the work surface of a desk can move very quickly through documents lying on it, but especially through an existing one Essay is limited. The latter is mostly used to accommodate forms and Writing implements, so that it comes into use only temporarily. It is therefore expedient and advantageous, the essay retractable and at the same time the whole desk to set up lockable. In order to use the entire work surface of the Table and, if necessary, also the essay with its contents for use as well Even when the table is not in use, all desk compartments can be locked in the simplest possible way This desk is created to be able to work from just one place been. This desk is characterized by a retractable attachment with its movement and locking device, also with a simple one Overall design, due to the omission of the roll-up cover and the required Sidewalls is achieved.

Due to the inherent

like design is simultaneous with the; Sinking the attachment automatically locks of the drawers in the desk. Only the middle drawer has to be still to be specially completed, since the same, as explained below is, at the same time serves to free the attachment and the drawer from their locked position.

ίο The attachment is sunk held in place by a locking spring that automatically snaps into place during its downward movement. The same is so on a double-armed, with the middle drawer in connection standing lever connected so that when the drawer is pushed inwards, it opens the attachment releases. This results in the essay as a result of weights acting on it in Position of use. The simultaneous locking of the drawers when lowering the attachment is achieved by the fact that the latter a shift from inside the desk when going down located locking bars caused, which by angle hooks located on them enter eyelets located on the back walls of the drawers, causing the drawers are locked.

In the drawing, the desk is shown in an exemplary embodiment, and although shows

Fig. Ι a cross section along the line AB of Fig. 4 with a sunk attachment, while

Fig. 2 shows the same cross-section with the attachment in the position of use and

Fig. 3 is a cross-section along line CD of fig. the

FIG. 4 illustrates a longitudinal section along line DF in FIG. 1.
The essay α is retractable in the desk and is connected to weights d by means of cords c running over rollers b , the dimensions of which are held in such a way that the essence α is held in the position of use by the weights d pulled upwards.

When countersinking the attachment α , the weights d must be overpressed. The attachment is held in its sunk position by the locking spring e , which automatically snaps into place, in that the spring is equipped at its upper end with a nose-like projection / "which is placed in an eyelet g at a suitable point on the attachment. The spring is on the base plate h Attached to the upper end of the spring e is a double-armed lever k rotatably mounted at i , the upper free end of which lies against the rear wall of the middle drawer I.

If the middle drawer I is pushed inwards (Fig. 3), the lever k goes into deflection and lifts the nose-like attachment f out of the eye g . In this way, the attachment is free and automatically moves into the position of use.

When the attachment is depressed, it also causes the double-armed lever m protruding into its path to deflect, in that the bottom of the attachment α rests on the free end of the lever. The latter thereby displaces a locking bar η connected to it upwards, as a result of which angle hooks 0 provided on it penetrate into eyelets q provided on the rear walls of the drawers ft , so that the drawers ft are locked by the lowering of the attachment.

If the attachment α moves upwards by pushing the middle drawer I inwards, the locking rods η are pulled back into their initial position by the spring r influencing them, so that the angle hooks 0 emerge from the eyelets q and the drawers are unlocked.
