DESCRIPTION OF A PREFERRED EMBODIMENT Referring to FIGS. l-9, a foldable table and seating structure 10 is shown. The table structure 12 thereof comprises a pair of top plate members 14 and 1S rectangular in plan in longitudinally spaced relation with each of said plate members having disposed thereunder opposed pairs of rails 18 and 20 adjacent either side edge portion thereof and extending lengthwise thereof. The adjacent ends of said rails are hingedly connected as at 22 and 24 here shown as overlapping extended porting members are cross bars 40, 41 and 42. Consequently said bars -41 and said bars 41-42 respectively are linking bars 45 and 46 rotatably connected at their respective ends to said cross bars.
In the particular embodiment here described, bar members 49 and 50 respectively underlie the members 30-31 and 36-37 and extend outwardly of said table 12 at each side thereof. Said bar 49'is shown having unstanding tubular members 52 and 53 at the ends thereof and integral therewith, said members 52 and 53 having suitable supporting castors 54. The bar 501has upstanding terminal supporting tubular members 56 and 57 suitably supported by castors 54. Carried at the upper ends of said supporting members 52, 53, 56 and 57 respectively are cross bar or arm members 61-64.
The supporting members 33 and 34 are self-standing as indicated in Fig. 4 having end caps or glides 58. Extending outwardly of said members 33 and 34 are simply formed brackets 68 and 69 as illustrated and having at each outer end thereof ground supported upstanding tubular members 71 and 72 and extending outwardly thereof are handle members 77.
Said tubular members 71 and 72 have inner tubular members 73 and 74 which have free upward movement and said members 73 and 74 carry upper cross members 75 and 76 and said cross members carry double plate hinges 78 and 79.
The seating structure at one side of said table 12 is indicated generally by 80 and is a mirror image of the seating structure 81 at the other side thereof which is.
described hereafter in further detail.
The seating structure 81 comprises a pair of elongated substantial rectangular plate like members 85 and 86.
Said seat members 85 and 86 as shown in FIGS. 1 and 2 have-at their remote end portions brackets 90 and 93 which will be suitably secured thereto and said brackets have downwardly angled oppositely extending open ended slotted plate portions 91 and 94 to slidingly receive therein the cross bars 62 and 64 as indicated in FIG. 2. r
A pair of depending link members 97 and 98 have their upper ends pivoted to conventional bifurcated bracket members 96 suitably secured to the under side of said seating members 85 and 86 as illustrated and the lower ends thereof are pivotally removably secured as by thumb screws 100 to the bifurcated ears 101 projecting oppositely from the lower portion of said tubuiar member 72.
With reference to FIGS. 10 and an alternative means is shown for the structure of the brackets 90 and 93 wherein an open ended channel member such as channel member 105 receives the cross bar 62. Said channel member 105 comprises a pair of spaced angled members 106 and 107 having retaining flanges as shown to receive and support therebetween said cross bars such as cross bar 62.
OPERATION The table and seating structure is shown in FIG. 1 in horizontal position for use. To be folded for storage purposes, the handle 77 is grasped by hand and raised. The torsion bars operate to have but little force required to raise the table upwardly centrally to the positions as shown in FIGS. 5, 8 and 9. The links 97 and 98 r are of such length that the seat members 85 and 86 are moved upwardly to reach the same height as that of the folded table with said seat members sliding upwardly of their supporting cross members as permitted by the brackets 90 and 93 whereby in fully folded position the seating structure is. co-extensive in height with the height of said table 12 and the inner tubular member 74 is raised upwardly relative to said outer tubular member 72. The thickness of the folded seat structure is confined to and corresponds to the thickness of the table in folded condition. By removing the thumb screws 100 from the ears 101, the seat members 85 and 86 may be lifted clear of the supporting seat structure for separate storage if desired or for ready replacement of said seat members.
MODIFICATION Referring to FIGS. 12-19, a modification of the above described structure is shown and elements of structure therein identical to those above described will be referred to or incorporated by reference in being indicated by like reference numerals.
The table structure 12 is here shown having a modified leg structure and in lieu of the leg members 30-31 and 36-37 which are supported by the cross members 49 and 50, said table structure 12 in the embodiment here presented hasself-standing legs of which leg member 111 and its attendant structure is representative and which leg member is shown supported by castor 115.
Extending outwardly of said leg member 111 as at tendant structure is a bracket member 117.
Said bracket 117 comprises anarcuate or half round channel member 120 of some length disposed in mating engagement with the outer surface portion of the leg member 111 and is secured thereto by a nutted bolt 121. Said channel member has a plurality of apertures 122 therethrough and said leg member has a single aperture therethrough not here shown for alignment of apertures 122 therewith to receive said bolt 121 for vertical adjustment of said channel member relative to said leg member for height adjustment of the table. A
' cross member 124 shown asa straight tubular member extends outwardly off said channel member 120 and has at its extended end an upstanding tubular support or leg member 126 which has threaded upwardly into its lower end a height adjusting means 127 shown here as a leveling screw.
Said leg member 126 hasan inner tubular member 129 slidable therein with a plurality of apertures 130 extending through each of said members adapted to receive a nutted bolt 121 therethrough for relative height adjustment of said inner member 129. Said member l29c'arries cross bar 62 which isslidably receivable into the bracket member 90.
In connection with said castor 115, reference is had to FIGS. 15-17 wherein the stem portion 115A of said castor is shown carrying a pair of spacing collars 115B and 115C whereby the leg 111 may be supported by said castor in connection with said spacing collars at variousheights relative thereto as shown.
Referringto FIG. 14, extending outwardly of leg member which is representative of leg members modifying leg members 33 and 34 is an adjustable bracket 132 shown in lieu of the brackets 68 and 69. This bracket comprises a unitary cross member 134 which is like cross member 69 but which at its inner end is integral with a semi-round channel member 136 which mates with the outer side of the leg member 135 and is secured thereto through accommodating apertures by a nutted bolt 121 which may be disposed selectively through apertures 140 of said channel member to position said bracket at various heights relative to said leg 135. Said leg member is shown having a height adjusting screw 127 in connection therewith.
Said cross member 132 at its outer end has integral therewith a support or leg member 143 having a slidable inner tubular member 144 as shown at FIG. 14 and the same is like the member 72 but has a height adjusting screw 127 for adjustable support.
MODIFICATION Referring now to FIGS. 20-22, a modification is shown of the bracket structure 132 by the bracket structure 149 in which a curved channel member 150 is shown secured to the leg member 135 through accommodating apertures by nutted bolt 138. Additionally vertically spaced apertures 152 are provided in channel member 150 for height adjustment thereof relative to said leg 135. A tubular cross member 154 extends outwardly to an upstanding tubular supporting or leg member 155 integral therewith. Said tubular member 155 has an inner tubular member 156 slidably disposed therethrough carrying at its upper end cross bar 75 which forms a hinge pin for hinges 78 and at its lower end it has a height adjusting screw 127. Extending outwardly of said member 155 at the level of said cross member 154 is a handle 77. I
A collar 158 is disposed over said member 155 slidably thereof having a thumb type set screw threaded thereinto as shown in FIG. 22, the member 155 has an aperture 157 therethrough as has the inner tubular member 156 and when said tubular members are positioned as in FIG. 20, said apertures are in register. Said set screw 160 may be threaded inwardly to engage only the member 155 or it may be threaded'inwardly further to also engage the member 156 to hold the member 155 and member 156 in interlocked position. Said collar 158 has apertured ears 158A to have the link member 97 and 98 thereto as by rivets 151.
Thus when it is desired to remove the seats 85 and 86 the set screw 160 is withdrawn sufficiently to permit the removal of the collar 158 from the member 155 and the member 156 is fully withdrawn from said member 155. For folding the table and seating structure, the set screw is merely withdrawn from engagement with the member 156 to permit the relative sliding movement thereof as shown in FIG. 5.
MODIFICATION Referring now to FIGS. 23-27, a further modification is shown of the bracket structure 132 by the bracket structure in which a curved channel member 171 is mated with the outer side portion of the leg member 135 to be secured thereto by nutted bolt 121 disposed through an accommodating pair of apertures. A plurality of apertures 173 are provided in the channel member 171 for vertical adjustment of the channel member relative to said leg 135.
Extending outwardly of said channel member 171'are a pair of horizontal vertically spaced tubular members 175 which have secured to their extended ends an elongated plate member 178. Slidably disposed over said member 178 to be normally positioned at the bottom thereof is a channel shaped collar 180 as illustrated in FIG. 27 having apertured ears 181 projectng from the ends thereof as shown and a small rectangular boss 183 projecting forwardly thereof and said collar and-boss are tapped to receive a set screw 185. The links 97 and 98 are pivoted to said ears 181. An angled support bracket 190 is provided having an upstanding wall 191 slotted to receive said boss 183 and having a lower body portion 192 extended to underlie said collar 180. Said wall 191 is apertured to receive said set screw and leveling screw 127 is threaded into and supports said bracket 190.
Slidably disposed over said plate member 178 to rest upon said collar 180 is channel sliding member 192 having a handle 77 extending outwardly thereof and having an upward ear like projection 194 apertured to have disposed therethrough the hinge bar 75.
Thus in raising the table seating structure into folded position, the set screw will be threaded into holding engagement with the plate member 178 and as the handle 79 is raised the same folding action is present as shown in FIG. 5.-
When it is desired to remove the seats from the table structure, the set screwis withdrawn from the plate member 178 and the collar 180. The bracket is then free for removal and the member 192 and the collar 180 slide free of the member 178 for removal which in effect is as what is shown in FIG. 22.
The detachable bracket members such as 117, 132, 149 and 170 are readily removed by removal of the bolt 121 and the table structure is usable free of any projecting members.
There have been provided a simple, efficient and effective seating structure in connection with a centrally upwardly foldable table structure.
