FOLDABLE PICNIC TABLE Filed Dec. 1, 1964 2 Sheets-Sheet 2 a2 LUA L26 IO/ 32 H G 7 INVENTOR Joseph Giumbalvo ATTORNEY United States Patent 3,256,037 FOLDABLE PICNIC TABLE Joseph Giambalvo, 1118 Willoughby Ave., Brooklyn, N.'Y.

Filed Dec. 1, 1964, Ser. No. 415,033 6 Claims. (Cl. 297159) This invention relates generally to collapsible table and seat assemblies and more particularly to a unitary structure which can be conveniently folded into relatively small and very compact form for storage or transportation purposes and which may be readily unfolded into operational position without the need of tools, tightening or adjustthe opened operational position. The minimal leg length requirement of devices constructed according to the instant disclosure renders such devices extraordinarily practicable especially insofar as automobile luggage compartments can usually accommodate them with room to spare.

Accordingly and consonant with the foregoing, the primary object of this invention resides in the provision of a foldable picnic table which when in the unfolded operative position will be of conventional height and when folded will occupy an unexpectedly small amount of space relative to the operational size of the table.

Another object of the present invention is to provide a unitary device which affords free movement of associated elements from a folded to an unfolded operative position and which maintains such elements in erected position and permits ready movement of the elements into the folded storable position.

A further object of the instant invention resides in the provision of a foldable picnic table which includes novel support and brace elements and which, therefore, is exceptionally strong and lightweight in view thereof and still .compactly foldable for storage and carrying purposes.

Another object of the present invention is to provide a device of the foregoing character which may be fabricated of wood, metal, or other suitable material.

Another general object of the present'invention is to provide a foldable picnic table which will be simple in structure, economical of manufacture, easily and quickly erected and highly effective in use.

Patented June 14, 1966 FIGURE 7 is a fragmentary view of the table leaf sections in edge abutting relation, the cleat and tiebar being illustrated therein.

Referring now in detail to the present preferred embodiment of the invention illustrated in the accompanying drawings, FIGURE 1 shows the foldable picnic table designated generally by numeral 1 and shown therein in the unfolded operative position.

As more specifically disclosed in the drawings taken collectively, the table will be seen to comprise spaced pairs of legs 2 and 4, legs 6, 8 and :10, 12 of each respective pair having inner edges 14 and outer edges 16, said outer edges each having an elongate recess 18 of generally rectangular-configuration whereby a square corner 20 is formed at the upper end of each said recess, the inner edges 14 of respective pairs of legs, e.g., 6, 8 being mitered approximately 45 at the upper end 22 thereof as illustrated in detail in FIGURE 3. Thus, when in the un-. folded position said legs will assume an approximately 90 angle as shown in FIGURE 4 by dint of the mutual abutment at 24 of the aforesaid 45 mitered inner edges 14.

Main beam member 26 extends between said pairs of legs and is disposed between the upper ends thereof as shown in FIGURE 5 of the drawings. Said beam is connected at either end to respective pairs of legs by a pivot member 28, hinge sections 30 and 32 being rotatable about said pivot member and each section is respectively secured to a respective leg as specifically shown in 'FIG URE 4. Nut 34 retains said legs and beam member in the pivotal arrangement shown and described. When the respective pairs of legs are folded whereby parallelism of said legs is etfectuated as shown in FIGURE 3, hinge sections 30 and 32 similarly assume respectively parallel positions. Accordingly, it will be appreciated that said legs are movable between a folded position,

' wherein said legs are substantially parallel, and an unfolded position, wherein said legs are arranged at an approximately 90 angle.

' In addition to the aforedescribed main beam member 26, beams 36 and 38 are provided to rigidly connect the lower ends of .opposed legs 6, 10 and 8, 12, respectively,

Other objects and advantages of the instant foldable picnic table will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice of the invention, the same being realized and attained by means of the structure defined and pointed out in the appended claims.

The accompanying drawings referred to herein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

FIGURE 1 is a perspective view of the instant picnic table in the unfolded operative position;

- FIGURE 2 is an end elevational view of the unfolded table shown in FIGURE 1;

FIGURE 3 is an end elevational view of the picnic table in the folded inoperative position;

FIGURE 4 is an end view of the picnic table in the partially unfolded position;

FIGURE 5 is a fragmentary side elevational view of the present apparatus taken along line 55 of FIGURE 4, parts thereof being shown in cross-section;

FIGURE 6 is a fragmentary end elevational view of folded and unfolded position; and

of said spaced pairs of tlegs 2 and 4. Beam 36, only an end of which is shown, is identical in kind and relative position to beam 38, the latter being more clearly seen in FIGURE 1. Thus it will be understood that while beams 36 and 38 move with the pairs of legs as they are folded and unfolded, main beam 26 remains stationary with respect to said legs and remains centrally disposed intermediate said legs as shown in FIGURE 3 and opening 40 provided therein serves as a carrying handle to facilitate manual transportation of the device.

Table leaf sections 42 and 44 as shown, have upper and lower surfaces 46 and 48, respectively, and a tongued longitudinal edge 50 and a grooved longitudinal edge 52. Leaf support members 54 are each provided to occasion the support of said table leaf sections, an end 56 of each support member being pivotally connected to a leg with individual connector plates 58 being the pivotal connection therebetween. Such pivotal connections are, as shown, accomplished within the upper ends of said elongate recesses 18 and adjacent the square corners 20, the other end 60 'of each leaf support member being pivotally connected to the lower surface 48 a respective leaf section. As will be observed in FIGURES 2 and 4, e.g., brace members 62 are fixedly positioned with respect to said table leaf sections and support members 54 are connected to said leaf sections via said brace members, pins 64 providing the pivotal linkage therebetween. The aforesaid square corners 20 so provided at the upper end of said leg recesses, perform as stop means by functioning to restrain said leaf support members in perpendicular relation with respect to the respective leg to which they are connected. As shown in the drawings, the leaf support members when arranged perpendicularly as described, extend substantially above the upper ends of said legs when the latter are in the unfolded 90 position. The table leaf sections being held above the upper ends of the legs, may be arranged in tongue-in-groove edge abutting relation as shown in FIGURES l and 2, parting line 66 lying centrally and longitudinally of the continuous table surface which is formed, said table surface being disposed in an horizontal plane spaced substantially above the upper ends of said legs. That is to say, the space D in the construction shown is equal to approximately onethird the height H of the unfolded legs. The import of the foregoing resides essentially in the provision of a construction whereby the height of table surface may be relatively high in comparison to the height of the unfolded legs and still render a relatively compact and short folded assembly. It will be understood that the magnitude of space D may vary depending upon the length of support members 54, the length of the latter being limited by the length of the legs and therecess capable of being formed therein. As shown in FIGURE 7 of the drawings, cleat 68 and tie-bar 70 attached to the lower surfaces 48 of respective leaf sections, are mutually engage-able to retain said leaf sections in edge abutting relation.

With reference now to FIGURES 4 and 5, upright members 72 will be observed, said members being pivotally connected to beam 26 within the spaced recesses simi larly designated by numeral 74, hinge elements 76 being thee pivoting instrumentalities. As shown, said upright members are movable between a vertical position wherein the free ends thereof are receivable within respective transverse notches 78 which extend across parting line 66 and thus provide support for said edge abutting leaf sections, and a folded position wherein they lie flush within said recesses 74 of said main beam.

With further reference to the drawings, the foldable picnic table will be seen to include a pair of seat sections 80 and 82. When the seats are in the horizontal operative position illustrated in FIGURES l and 2, seat support members 84 partially support said seat sections, one end of each seat support member 84 being pivotally connected to a respective leg by a respective pin 86, and the other end theerof being fixedly secured to a respective seat section as shown. As will be noted, the pivotal connections at pins 86 are provided intermediate the upper and lower ends of said legs, such arrangement thus enabling said seat sections to be folded coextensively with respect to the length of the legs as shown in FIGURE 6. Seat support members 88, pivotally connected at one end by pin 90 to seat support members 84, respectively, are removably securable upon a respective beam 36 and 38 at the other ends thereof by reason of the concavity 92 provided within said other ends. Accordingly, by dint of said supporting arrangement, members 84 and 88 cooperatively and fully support said seat sections in a plane substantially parallel with said table surface when said legs are in the unfolded position. Also, as shown in FIG- URE 3, respective pairs of leaf and seat sections 42, 80 and 44, 82 are disposed in the same planes when said legs are in the folded position.

It will be appreciated that the angular relationships between the foldable elements of the foldable picnic table assembly may be varied and still provide an operative structure, the angular relationships herein described being preferred and exemplary.

The instant structure may, it will be understood, be constructed of any suitable materials such as wood, steel, aluminum, or plastic, lightness and durability factors being considerations in the choice of materials. Also, it will be obvious that the table may be used indoors and outdoors, and for purposes other than picnic occasions.

Although the preferred embodiment of the foldable picnic table has been described, it will be understood that within the purview of this invention various changes may be made in the forms, details, proportion and arrangement of parts, the combination thereof and mode of operation, which generally stated consists in a device capable of carrying out the objects set forth as disclosed and defined in the appended claims.
