FOLDING AUXILIARY TABLE Filed Oct. 8, 1962 3 Sheets-Sheet 5 5g INVENTOR 444: MrMs United States Patent 3,152,149 FQLDING AUXHJIARY TABLE James G. Hansen, Deerpath Road, Batavia, Ill. Filed Get. 8, 1962, Ser. No. 228,806 7 Uairns. (ill. NSF-7%) The invention relates to an auxiliary table of the folding type and has reference in particular to such a table having two similar sections pivotally secured together and wherein each section provides a table of semi-circular area, triangular area or other geometrical shape.
An object of the invention resides in the provision of an auxiliary folding table which when completely erected will be round in area or two pivotally connected tables can be formed each semi-circular in area, and said auxiliary folding table when partially erected providing one table of semi-circular area.
A more specific object is to provide a folding type of table which may have a top surface of round area or which may be square or other geometrical shape and a table which when completely folded will provide a handle for carrying the folding table and which will be flat on both sides for convenient stacking.
A further object is to provide a folding table essentially consisting of two sections pivotally secured to each other and where in each section is in turn pivotally secured to a semi-circular table top along a flanged edge extending diametrically of the table top or if the top is triangular then the flanged edge will comprise the hypotenuse.
Another object of the invention is to provide a folding type of table wherein the supporting structure and table top includes two similar sections pivotally secured to each other and wherein each section comprises a twolegged unit having a third leg pivoted thereto.
With these and various other objects in view, the
invention may consist of certain novel features of construction and operation, as will be more fully described and particularly poined out in the specification, drawings and claims appended thereto.
In the drawings which illustrate an embodiment of the device and wherein like reference characters are used to designate like parts FIGURE 1 is a top plan view of the folding table of the invention showing the same completely erected to provide a round table area;
FIGURE 2 is a top plan view showing the folding table -of FIGURE 1 in complete folded condition;
FIGURE 3 is an elevational view of the table as shown in FIGURE 1;
FIGURE 4 is an elevational view showing the table as it appears in the completely folded condition of FIG- URE 2;

3,l62,l49 Patented Dec. 22, 1954 'ice to each other and wherein each unit has a pivotal connection with a third leg member 14 and 15. Each of the units It and 12 include a horizontal bar 16 and a pair of legs 17 and 18 for unit 10 and a horizontal bar 20 and the legs 21 and 22 for unit 12. The third leg member 14 consists of the horizontal bar 23 and leg 24 with the said bar 23 being pivotally connected at 25 to the horizontal bar 16 of unit 16. In a similar manner the third leg member 15 consists of a horizontal bar 26 and a leg 27, said bar 26 being pivotally secured at 28 to the horizontal bar 20 of unit 12. The legs 17 and 21 are pivotally connected to each other by hinges Sil, FIGURES 3 and 4, and thus the units 10 and 12 can be spread apart or the units can be folded into contact with each other and secured in such folded relation by removable screws, mechanical fasteners, or other devices to hold the units 1th and 12 secured to one another.
The units It) and 12 and the-thirdleg members 14 and 15 may be formed of aluminum, steel or other suitable material and the material may be solid or tubular. As regards both the units and the third leg members, the same are so shaped as to provide the upstand portions 32, with each portion being integral with and forming an extension of its leg and the horizontal bars being also integral with or being suitably welded or mechanically fastened to their respective structure. I
Referring to FIGURES 3 and 5 it will be clearly understood that the top sections of the table can be described as located within the confines of the portions 32. The said top sections 33 and 34 are shown as semi-circular but their specific shape is not limiting in any sense in that square, triangular, hexagonal or other shapes may be employed. Each top section includes the surfacing material 35 which may consist of a plastic, leather, cloth or other material suitable for a table top and which is backed by the layer of wood, metal, plastic, or any .other suitable reinforcing material, such as 36. Here,
also, for this table a plastic material or metal could be substituted for the wood. The peripheral edge of each semi-circular top section is provided with a depending flange 37-and the same may be reinforced and strength ened by reinforcing material of wood, metal, plastic or any other suitable material at position 40 or the depending flange may be non-existent, or may be an integral part of or non-separable from reinforcement 40.
The top section 33 is hinged to the horizontal bar 16 of the unit 19 and top section 34 is hinged in a similar manner to the horizontal bar 20 of the unit 12. For the diametrical edge of each semi-circular top section is provided with an angle member having a horizontal flange 41 and 42 for the sections 33 and 34 respectively, and a depending flange which is designated by the numerals 43 and 424, all as shown in FIGURE 5. The rivets 45 secure the horimodified form of pivotal connection for the table sections;
The supporting structure of the present folding table is best shown in FIGURES 4- and 8 wherein it will be observed that the units It and 12 are pivotally secured zontal flanges to their particular top section and each depending flange has a hinge such as 46 and 47 suitably secured thereto with the axis of the hinge coinciding with the bottom edge of the depending flange. For the top section 33 the hinge 46 is in turn fixed to the horizontal bar 16 and for the top section 34 the hinge 47 is secured to the horizontal bar 20. The diametrical edge of each top section overhangs its depending flange to an extent such as to provide a shallow recess for accommodating the handles 50 and 51. The said handles are thus completely enclosed when the top sections are horizontally disposed. However, the handles are con venien'tly accessible. to the operator when the table is in v a completely folded relation.
It is relatively easy to erect the folding table either to provide the full circular table of FIGURE 1' or the two half sections as shown in FIGURE 7. The third leg members 14 and 15 are revolved into a right angled ,units can be spread apart relation, with their respective horizontal bar either 16 or 20, and the spring clips 52 which depend from each top section will engage the horizontal bar 23 or 26 to yielding hold the third leg members in extended relation. In addition to the full round table of FIGURE 1 and the two half sections of FIGURE 7, the auxiliary table of the invention can be partially erected to form a single half section. In such case the third leg member either 14 or 15 is released from its spring clip 52 and folded in against its particularhorizontal bar to which it is pivotally secured. This will drop the semi-circular top section of the particular third leg member and the table is thus only half erected and half folded. 'When completedfolded the handles 50 and 51 are exposed to facilitate the carrying of the folded table. It Will also be observed that the table when completely folded is fiat on both sides to enable a stacking of the tables on top of each other for shipment or for the other purposes.
The hinges 46 and 47 can be replaced by a hinge structure such as shown in FIGURE 10. IA plate 54 is suitably secured to the undersurface of each table section by the rivets 55, and said plate provides a depending flange 56. A bracket 57 providing portions at right angles to each other is suitably fixed to each of the bars 16 and 20, and a pivot pin 58 connects each flange 56 to its bracket 57. v r
The invention is not to be limited to or by details of construction of the particlar embodiment thereof illustrated by the drawings, as various other forms of the device, Will be course be apparent to those skilled in the art Without departing from the spirit of the invention or thescope of the claims.
