H. l. COHEN NESTING TABLE March v27, 1956 Filed Nov. 18, 1954 EYSI United States Patent Off NESTING TABLE Henry I. Cohen, New York, N. Y.
Application November 18, 1954, Serial No. 469,866
3 Claims. (Cl. S11-16.5)
(Granted under Title 3S, U. S. Code (1952), sec. 266) The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the pay ment of any royalties thereon or therefor.
This invention concerns nesting tables.
An object of the invention is to provide a nesting type table which collapses into a small compact area when not m use.
A further object of the invention is to provide support for a table top which is stronger and yet more readily collapsible than in prior types of nesting tables.
Still a further object of this invention is to provide a nesting type table utilizing a structure which is foldable upon application of upward pressure only, and which, when in support position for the table, may not be collapsed by the application of downward pressure on the table top. j
Other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
Fig. 1 is a side elevation of a nesting table, or the like, embodying my invention.
Fig. 2 is a front View of a nesting table embodying my invention.
In Fig. l, the numeral 1 denotes the table top which is aiiixed to a table top support 2 which is joined to a cabinet 1S by a pivot 9. The table top 1 is adjustable in elevation by the elevator and clamp arrangement 3, which may be of any type known in the art, and which is not of essence in this invention. Aiiixed to the underportion of the table top supporting member 2, is a pivot juncture 1i) to which is attached arm 4; the other end of arm 4 is pivotally affixed to the member which, in support position, rests upon the same surface as the cabinet 15. The member 5 is of straight beam configuration for about three quarters of its length; it then bends at a very slight angle with its former position to continue for the remaining quarter of its length as a straight beam. Pivot juncture 11 is a common junction point for arms 4, 5 and 7. Arms 4 and 7 form a knee joint, at the pivot point 11, ,which breaks downward. Arm 7 and the upper quarter of arm 5 form the adjacent sides of a parallelogram composed in its entirety of arms 5, 6, 7, and the vertical side portion of the cabinet 15. The other end of arm 7 is attached by pivot 14 to the cabinet 15. The arm 6 is joined at one end by pivot 13 to the cabinet 15 and at its other end by pivot 12 to the upper quarter of arm 5. The battle stop 8 acts to seat the table top 1 in position when folded in the cabinet; it prevents injury to the elevator and clamp arrangement 3 which would result if the tabletop were to strike the back of the cabinet. Baflle stop 8 is hinged; it is hooked in the position shown.
The operation of the nesting table is as follows:
In its vertical position, the arm 5 acts to support the table top directly through the arms 4 and 2; Figs. 1 and 2 2,739,859 Patented Mar. 27, 195.6
indicating this supported position. To nest the table, how ever, pressure must be applied in an upward direction t0 any of the arms 4, 6 or 7, or at the pivot points 11 or 12. The application of any downward pressure at any of the pivot points by the ordinary use of the table top 1 will not of arm S in vertical position without slippage of any kind.
Upon the application of an upward force (which is usually manually applied) to either the pivot point 11 or 12 the arms 6 and 7 will move in an upward arcuate direction toward the cabinet 15, as will the arm 5; the arm 4 moving toward the table top in an upward arcuate direction about its pivot point 10 and the arm 5 moving toward the cabinet 15 in an upward arcuate direction about the pivot points 13 and 14. 'Ihe arm 5 is supported by the arms 6 and 7 in this upward movement; the function of the arm 7 being primarily to position the arm 5, and the function of the arm 6 being primarily to hold `the arm 5 in position for table top support. As the arms 4, 5, 6.and
7 are moved into their folded positions, the table top 1 and the tabletop support 2 move arcuatelyk downward to nest in vertical position in the cabinet 15 when the under portion of the table top 1 comes to rest against the stop 8.
The nested table thus presents a compact cabinet structure which may, agairnbe opened to operative position by i moving the table top 1 in arcuate direction upwards and outwards away from the vertical area of the cabinet 15.
This movement acts to extend the arms 6 and 7 away: from the cabinet 15, thus extending arms 4 and 5 intoV their support positions, as shown in the figures.
Obviously many moditications and variations of the present invention are possible in the light of the above teachings. It is therefore to'be understood that within thev scope of the appended claims the invention may be practiced otherwise than as specifically described.
I claim: l. A nesting table comprising, a support, a table top pendulously attached to the top of said support for movement about a horizontal axis, means pivotally attached to the lower half of said isupport and forming with the portion of said support to which it is attached an articulated parallelogram, said means being swingable vertically relative to said support, support means integral with and extending vertically downward from the side of said articulated parallelogram opposite said support, said support means being of such length that when its free end is supported at the same level as the bottom of said support said first-mentioned means slopes upwardly from said support, an arm pivotally attached at one end to said table top remote from it-s pivotal attachment to said support and pivotally attached at its other end to said parallelogram along the side thereof remote from said support, whereby it defines an upwardly opening obtuse angle with the slope of said parallelogram when said end of said support means is supported at the same level as the bottom of said support.
2. A nesting table comprising, a support adapted to rest on a iioor, a first pivot secured to the top of said support and dening a first horizontal axis, a second pivot and a third pivot secured to the lower half of said support and defining a second horizontal axis and a third horizontal axis, respectively, both of which are parallel to the first horizontal axis, the third horizontal axis being closer to the bottom of said support, a table top pendulously attached to said first pivot, a rst arm attached at one end thereof to said second pivot, a second arm of equal length to said iirst arm secured at one end thereof to said third pivot, a supporting member, one end of said supporting hierber being piiotally' attached to the other end of said rst arm,` the other end of saidy second arm being pivotally attached to said supporting member intermediate the ends thereof, whereby said first and second armsare in parallel relationship at aillv pivotal positions thereof, and the por'- tio'n of said supporting member between itspivotaljattachnientA fo said secor'id arrii arid the other end thereof is vrtic`a-l for all pivotal positions of said arti-is, the' length of the last-mentioned portion of said supporting member' being' greater than the height of said third pivot above= the bottoni of said? support, a thirdarm pivotally att-achedl at one end thereof to said table top remote from said first pivdtand pivotaliy attachedk at the other end thereof to` said other' end of said second ar'n, the length of said third arihbeing such that it deiines an obtuse angle with said s'ecciiid-` arr'n when said other end of said supporting member is at the saine level as the botto'm of said support, whereby the pivotal attachment between saidl second arm, said thirdari,` and said supporting member needY only be raised slightly to' pass through straight line relationship with said third pivot and the pivotal attachment between said third arh and saidtable top topermit said table top to drop peiidul'ously to substantialiy vertical position and whereby said table top'is returned Ato substantially horizon# tal position by swinging said table top far enough about saidL hist pivotv to permit the' freel end of said supporting rr'ie'rber to drop t'o the' same level as the' bottom of said supportv to be" supported thereat for retaining said table top iii a' substantially Horizontal position.
