July 21, 1964 o. DOMPIERI COLLAPSIBLE DRAWING TABLE 2 Sheets-Sheet 1 Filed Jan. 22, 1962 I-NVENTOR 0 7-7-0 DoMP/EE/ ATTORNEY July 21, 1964 o. DOMPIERI COLLAPSIBLE DRAWING TABLE 2 Sheets-Sheet 2 Filed Jan. 22, 1962 INVENTOR Orro DOMP/Ei/ BY Z/ ATTORNEY United States Patent 3,141,260 COLLAPSIBLE DRAWING TABLE Otto Dompieri, 92 Belmont Ave, North Piaintield, NJ. Filed Jan. 22, 1962, Ser. No. 167,779 4 Claims. (Cl. 45131) The present invention relates to a collapsible drawing table which can be adjusted readily to support the drawing surface in different inclined positions.

The principal object of the present invention is to provide a convenient, light and portable drawing table or stand which when not in use, can be easily folded to occupy a minimum of space for storage or transportation.

Further objects of the present invention are to provide a folding table having relatively few parts thereby enabling same to be inexpensively manufactured, which is sturdy in construction and which can be folded or set up with a minimum of effort.

Further objects and advantages of the present invention will be readily apparent from the following detailed description taken in conjunction with the accompanying drawings wherein:

FIGURE 1 is a perspective view of the folding table in operative position.

FIGURE 2 is a perspective rear view of the table shown in FIGURE 1;

FIGURE 3 is a perspective view of the table in folded or collapsed position;

FIGURE 4 is a sectional view taken on line 4-4 of FIGURE 2, and

FIGURE 5 is a sectional view taken on line 55 of FIGURE 2.

Referring to the drawings wherein like reference numerals refer to like parts throughout the several views, numeral denotes the table top and numeral 11 the side rails suitably secured to the undersurface of the top. The front edge of the table is provided with a conventional pencil or instrument retaining ledge 12.

The leg structure comprises the leg members 13 and 14 rigidly secured to each other by cross bars 15 and 16. The upper ends of the leg members 13 and 14 are pivotally secured to the front ends of the rails 11 by bolts 17. Pivotally secured to the underside of leg members 13 and 14 as viewed in FIGURES 1 and 2 by means of hinge brackets 18 is a second set of short leg members 19 and 20 braced by a cross brace 21. As seen in FIG- URE 5, the hinge bracket 18 includes a U-shaped member 22, the legs of which embrace the upper end of the short leg member and pivotally secured thereto by a bolt 23. Each U-shaped member is secured to leg members 13 and 14 by a screw 24. The upper end of each of the short leg members 13 and 14 is rounded on one edge as shown at to permit the pair of short legs to swing inwardly against the long legs when the table is collapsed. The edge opposite to rounded edge 25 is left square thus limiting outer swinging of the short legs when the table is being used.

A brace 26 which may be made of heavy wire as shown in the drawings is generally U-shaped with the free ends of the brace bent outwardly at 27 to form pivot pins which are receivable in openings 28 formed in the side rails 11. At the lower ends of the legs of the brace extension pins 29 are provided, said pins being receivable in either of a plurality of holes 30 formed in the leg members 13 and 14. It will be apparent that the inclination of the table 10 may be adjusted to any desired degree by inserting the pins 29 into selected openings 30.

In order to collapse the table for purpose of storage, the table is tilted to bring the legs 13 and 14 to a vertical position, causing short legs 19 and 20 to collapse against legs 13 and 14 as shown in FIGURE 3. The table top is raised slightly to disengage the brace 26 from openings 30 and then allowed to drop against the legs 13 and 14 as seen in FIGURE 3. Since both the short legs and the table top collapse against the long legs, the folded table occupies a minimum amount of space.

It will thus be apparent that the table shown and described is well adapted to produce the objects and advantages set forth. It will be understood that minor changes may be made in the details of construction without departing from the spirit of the invention except as may be required by the scope of the appended claims.

Having thus described the invention, what is claimed is:

1. An adjustable, collapsible drawing board stand comprising a drawing board, a pair of legs pivotally attached adjacent a front edge of said board, said legs having a plurality of complementary openings along the inner surfaces thereof, a second pair of legs pivoted to said first pair of legs intermediate the length of said first pair of legs, and a brace member pivotally secured to said board intermediate the front and rear edges of said board, said brace member having projections receivable in a selected pair of complementary openings to provide inclined adjustment of the drawing board.

2. A drawing board as defined in claim 1, said brace member being detachably connected to said drawing board and being of U-shaped configuration.

3. A drawing board as defined in claim 1, said drawing board having opposed depending rails and openings midway thereof, said brace member having outwardly directed projections receivable in said rail openings to provide pivotal movement between said brace member and said drawing board.

4. A drawing board as defined in claim 3, said brace member being of U-shaped configuration, and being detachable from said drawing board.
