It is thus evident that the table and 4 In the initial setting up of the table and, while the bench assemblies are still nested, it is possible to extend the supporting legs 28 and 33 `and otherwise fully prepare the benches for positionment on the door, ground or other surface as the case may be. When this method of erection of the benches is followed, it is a simple act to withdraw them from slideways 3T and swing the same under direction of arms 4G ateachend tonal position. The fact that the benches can be 'moved into and out of the slideways 31, whether or not the the convenience of handling the table, as will now be appreciated.

assemblies may be completelyfolded up and the -notch ,3,11 forniecliiil the inwardly rdirected face toreceive the end lips pf each of the seat planks.

Aswill presently appear, thev notches. 31 act as `slide-ways to permit lateral sliding movement of the, benchassemblies (Figures 6) when the same are movedbetween extended and nested positions.

An limportantfeature of the present constructionis disclosedv inther means for movably and foldably attaching each'of' the bench assemblies to the table. This means is found in the "arm members 40, one ysuch armbeing operably positioned at each endof each of the bench assemblies 24 and 2 5, and each further being vconnected to anadjacenttable leg-lzfina lost motion relation. In Figures 4, 5 and.6,' itcan be seen that the arms 40 are swingably and pivotally connected by a double-acting hinge `4`l1fto the outerv end of the bench cleats `2'Land extenddownwardly and Darallel to the adjacent table legs l5. Near the lower-end, of eachsuch arm 40, a longitudinal vslot 42 is 4providedto receive in loose fitting relation the shank portionof a guide `and support pin=43iixed in the table leg. lIt isimportant to note that the hinge member 4l for .each arm v4l! provides for hinging action thereof .in a direction to allow it to move witlrthe.- table'legs `as they fold and unfold (Figures Zand 4). In addition, each, =of the arms-is free to swing in, a lateral direction or parallel tothe benchcleat to which it isA attached (Figure-9).

ysome lateral-movement of the bench assemblies blies each comprise a ,wheel 46 carried on a bracket 41', which, in turn, is provided with a sleevevtype body 4B to, telescope over thelower end portion of the table leg i5. The sleeve body is preferably cylindrical, to match with' the shape of the leg p I5. Since y each wheel 46v of the assemblies extends belowthe4 `bracket 4.1'ffor groundclearance it is necessary to shorten'ithe leg' `length of that pair of legs with j which they are associated. Moreover, each of these wheel assembliesv is'arranged for limited swiveling movement, so that it can be folded in to retracted position, as inFigure 3, for completing the compact folded arrangement desired. Positional control ofjthe swivelingyassembliesis accomplished ,by means .of a laterally or circumferentially formed slot 5U near the upper end of .each cylindrical .body 48. Each slot 50 extends circumferentially over approximately degrees of arc `of the bodyv sleeve and terminates in a locking slot 5l directed at `90 degrees thereto. A cooperating pin 52 secured in the table leg rides in the slot and restricts the swiveling moveyment of' the. body.48. Preferably,i the slot 50 and locking slots 5i at each end thereof are l0- cated such that the wheel assembly may be secured infolded position (Figure 3,) with pin 52 in the appropriate locking slot 5|. When it is desired to `extend the Wheel assembly, the body sleeve 43 must be, moved longitudinallyoutwardly of the table. leg until pin 52 lcan slide in the lateral slot 5l, whereupon the assembly can be rotated 30l degrees, pin 52 then being received inthe opposite locking slot 5i lby .longitudinal inward movement ofl the sleeve 48. In this lat ter position, the weight of the table on wheel 46 will retain pin 52 in slot 5|. ,A study of the lseveraLviews of the drawing will be sufi'icient forunderstanding ofI the above described wheel assembly. l 4 j It should now be clearthat the presentlyv 'preferred wheel assembly arrangement will provide the means forrendering thev table easily portable either while` it is completedly folded, Aas inIFigzurec, orlwhen .1in various stagesof erection. viitl'rthe tableand ,side bench assemblies fully set up, Yas in Figure', it is possible to transport .the same.` on Wheels 4.6 by iirst moving the bench assemblies to nested positions' in slideways 3'1. Other. and furtherdetails .ofconstruction and assembly of the several parts and'co'inponent assemblies herein above described will become evident upon inspection of the drawing; While thepresent ldisclosure is a presently` preferred one, .it yshould be clearly understood that cerf tainQmQdiiiCatiOnsand minorfchanges in structure and disposition o'f parts may be made without departing'from tlierspiritand *full intended scope of the invention, thesame being-:defined in 'and'by-thefsubjoinedclaims. 1.11.
