DRAWING BOARD Filed Aug. 13, 1949 m1]. RE


BY @WM W A 7 7019/1/1 KS Patented Aug. 7, 1 951 Andrej Novy, Brunn, Czechoslovakia Application August 13, 1949, Serial No. 110,118 In Czechoslovakia November 10, 1947 2 Claims.

This invention relates to a drawing board assembly.

It is an object of this invention to provide a drawing board assembly which permits supporting a drawing board in an adjustably inclined position and which, at the same time, allows pivoting of the drawing board to an angular position in the plane of the board so that the draftsman is enabled to rotate the board to an angular position most suitable for the work he is performing.

In the drawings:

Figure l is a plan view of the rear face of the base member of my drawing board assembly.

Figure 2 is an end view of the base.

Figure 3 is a plan view of the rear face of the drawing board.

Figure 4 is an end view of the drawing board.

Figure 5 is a top view of the base member with the drawing board positioned thereon.

Figure 6 is an end view of the drawing board assembly showing the manner in which it may be inounted on a supporting surface such as a table Referring to the drawings, and particularly to Figure 1, there is shown a base member I on which the drawing board is adapted to be supported. Base I is preferably a flat rectangular wood panel having reinforcing cleats 2 on the rear face thereof extending parallel to and adjacent the side edges of the panel. Base I is also reinforced by a cleat 3 on its rear face which extends longitudinally of the base adjacent the upper edge thereof. Base I is adapted to be supported on a surface such as a table top I5 shown in Figure 6 by means of a pair of telescoping arms 5 and 6. Arm 5 is pivotly attached at one end to a bracket 4 which is fixedly mounted to the rear face of base I adjacent the upper edge thereof. Arm 6 is tubular in shape and adapted slida'bly to receive the free end of arm 5. The arms are arranged to be secured together in an extended position of adjustment by means of a pin 9 passing through arm 6 and through one of a plurality of longitudinally spaced holes II) in arm 5. At its lower end, arm 6 is pivoted to a C-clamp 8 which is arranged to be fixedly secured to the edge of top I5 by means of a wing screw I which is threaded into one 1eg of clamp 8. Arm 6 is attached to clamp 8 by means of a bolt and wing nut assembly I6 which when tightened holds arm 6 in the desired inclined position relative to table top I5.

At its central portion, base I is provided with a rectangular aperture II. Within aperture II,

there are mounted a plurality of parallel spaced rods I2. Rods I2 extend in a horizontal direction, that is, in a direction longitudinally of base I, and are secured at each end to the base. Rods I2 are spaced apart to receive, therebetween, a stud member I4 which projects from the rear face of the drawing board I3. Stud I4 is preferably secured to drawing board at its center.

When it is desired to arrange the drawing board assembly for use, base I is arranged on the supporting surface I5 in an inclined position. The extent of inclination may be adjusted by extending 0r shortening the combined length of arms 5 and B. These arms are locked in the adjusted extended position by pin 9 which passes through. arm 6 and one of the holes II! in arm 5. After the arms are adjusted to the desired extended position, the wing nut and bolt assembly It is tightened to hold arm 6 in the desired inclined position relative to top i5, screw I having been previously tightened to secure clamp 8 to the edge of the table top. When base I is secured to a table top in this manner, the drawing board I3 is mounted on the base by simply inserting stud I 3 on the rear face of the drawing board between an adjacent pair of rods I2.

Board I3 may be shifted to a position closer to or further from the draftsman by simply inserting stud I l between a lower or higher pair of rods I2. With board I3 mounted on base I in this manner, it will be appreciated that the drawing board is capable of being shifted longitudinally of base I and also of being pivoted to an angular position such as is shown in broken lines in Figure 5. It will be noted that the drawing board is supported entirely by base I and need not be additionally supported by the draftsmans chest in order to maintain it in either an inclined position or an angular position relative to base I. The friction between the top face of base I and the lower face of board I3 is sufilcient to hold the board in the position in which it is set.

It will thus be seen that I have provided a very simply constructed drawing board assembly which serves to support the drawing board in most any desired position. The assembly, furthermore, enables the position of the drawing board to be readily changed with a minimum of effort. The rods I2, it will be noted, form supports on which the drawing board may be shifted longitudinally on base I or pivoted to a desired angular position.
