Description

Countertop for combined drawing and desk -------------------------------- According to the current state of technology, it has not previously been possible to convert a writing or drawing table into a drawing table by simply turning the worktop, or vice versa.

The present innovation relates to this worktop, which by operating a lever and turning it by hand to almost any angle can be adjusted via a grid plate.

The development of the innovation is essentially characterized by that the combined drawing and writing desk without changing the exterior Turn shape into a drawing or desk by rotating the countertop leaves.

The innovation can be used as school furniture or office furniture.

The combined drawing and desk with the new work surface is shown in the drawing as an example.

There are: Fig. 1) Side view of the combined drawing and writing desk in the angular position as a desk inclination angle here 6 Fig. 2) Side view of the worktop in the angular position as a drawing table, Angle of inclination here, 20 400.

Fig. 3) Front view of the combined character-uhd desk in the position as a desk.

Fig. 4) Kinematic schematic diagram of the worktop adjustment device in the horizontal, opposite the chairman.

Individual parts: Part 1) Worktop "2) Stand" 3) Lever 4) Grid plate "5) Spring Part 6) Pastern Cam Rod 7) drawing board 8) desk board "9) Storage groove In the exemplary embodiment, the worktop 1) rests rotatably independently of the adjustment device 4) in two stands 2).

The angular positions of the worktop have been optimally points of view for the respective activity to be performed. By inserting additional grids in the grid plate 4), additional re any working positions for the worktop 1) achieved will.

The drawing board 7) is made of wood and can be replaced by a conventional detachable connection can be removed for any rework that may become necessary. The desk board 8) is covered with a plastic plate.

The drawing board 7) was used to store drawing pens with a Provide storage groove 9).

By pressing down the lever 3) the grid connection is through the grid cam rods 6) of the grid plate 4) released, so that the worktop 1) can be brought into the next desired angular position by turning it by hand can. The pressure of the spring 5) moves the grid plate over the grid cam rods 6) 4), which is firmly connected to the worktop 1), set again.

The shape of the worktop 1) was carried out so that at the position Sufficient knee-free height for the person sitting in front is guaranteed as a desk.

Also in the position as a drawing table for the chairman thanks to the shape of the worktop 1), adequate knee freedom is guaranteed.

The 00 position of the drawing table was chosen for the usual working position of construction technicians and the 20 ° and 40 ° positions for the usual working position of mechanical engineers.

The innovation is in the execution not on the drawn and described Example limited. There may be several discrepancies in the details and in the Form can be made that need not be discussed in detail here.
