7 Claims. (CL 190-111) This invention relates to a .table'case in which the case may be employed for carrying articles and, when desired, the case may be folded into .tableforming ,position. The invention is particularlyuseful asapicnictable, and when in case position, may be employed for carrying foldable stools, cutlery, and other articles.

The main difficulty with foldingtable structures heretofore employed is the lack'of rigidity in thestructure when moved to table-forming position, and further the .labor and time involved in settingup .the table. A problem has also been involved in the folding .and storing of the legs when the structure is converted into a case.

An object of the present invention is to provide a table structure in which the legs may be stored in nested relation to occupy a minimum of space .within the case, while, when the structure is formed'into a table, permitting the legs to be locked into the corners of the table-in an extremely sturdy arrangement. A further object is to provide in such a structure means forilockingtheadjacent hinged sides of the case into horizontal alignment .lfOI' forminga rigidtable. A still further -.object is ito;provide a-table and case structurein whichthe legs may be readily removed and folded in :nested relation when sthey are to :be carried within a case while at .thetsame time tpermitting them {to be rigidly grasped within 'theeorners -.0f :the table when the case is converted -to a :ta'ble. gOther tspecific objects and advantages will :appearas the specification proceeds.

The invention is shown, in an tillustratiue embodiment, bythe accompanyingdrawing,zinuwhich Figure 1 is a perspective view of lartable case;emb,odying my invention, the structurerbeingzshowniinrrase:position; Fig. 2, ..a perspective zview .of the rstructuredn ztable position; Fig. 3, a top plan view of the case with one portion of the case in horizontal position and the other portion in vertical zposition; Fig. :4, fan=enlarged 'broken sectional view, the section being taken as indicated :at line 4-4 of Fig. 3; Fig. 5, a broken perspective view of the retaining means employed forsecuring the "leg to .the .table; Fig. 6,'a front view in-elevation of the "latch mean-semployed for securing "the twoadjacent h'inged sides -,of;the table together-throughthe rotation of the latching .member;'and-Fig. 7,-a broken-sectional view,;the sectioniibeing taken as indicated at'line '77-of Fig. 6.

In the illustration "given, designates .one side'o'flhe caseand l-1 designates the "other-side of the case. Each side of the case is provided with a flat top portion 12 which, when brought together, as shown in Fig. 2, form a horizontal table. The case 10 is provided with depending side walls 100, and the case portion 11 is provided with depending side walls 11a. The adjacent side walls 11a of the two structures are connected by hinges 13. The case portions at their front sides may be provided with complementary catches 14 and 15, as shown more clearly in Fig. 3, conventional catches being employed, if desired. The case may be provided with a handle 16.

In order to latch the table portions 10 and 11 in the table posit-ion shown in Fig. 2, I prefer to employ a device such as the rotary latch bar shown in Figs. '6 and 7 of the drawing. The latch bar 17 is pivotally secured by pivot pin 18 upon the case wall 10a, as shown more clearly in ,Fig. 7. The latch .bar 17 is secured upon the pin 18 and is provided-with a-pair of spring-latching teeth 19 which are adapted, upon rotation ,of the latch bar 17, to pass through aligned openings 20 and 21 through the walls 16:1 and i'la so-as to latch the two walls together. The latch bar 17 is preferably provided with a thumb flange 22 to facilitate rotation of the latch bar. The teeth 19 .are preferably spring-like in character and are bent slightly in a direction to cause them to enter'the recesses 20 and 21 as the latch bar 17 is rotated clockwise :to bring the teeth into securing position, as illustrated in Fig. .6.

' Rotation of the latch bar 17 is acounterclockwise direction causes the teeth 19 topas-s throughthe slots 20-and21and to lie against the inner sidewall 10a only.

In the construction shown, I prefer to employ steel, plastic, or other suitable material for the forming of the case, and with suchthin-walled structure, the rotarylatch bar 17 is particularly-effective. The wide flangeof the latch bar 17 cooperating with the teeth 19 provide an extremely sturdy latch =which grips the side walls Illa and 11a of the case to'unite them firmly when the structure is in table-forming=position It is not necessary for the user tounscrew any parts or apply any specific devices for uniting the table sections; instead, it is merely necessary to rotate the latch bar device '17 for the locking or unlocking of the casing parts. I preferto .employ .a pair of latch bars 17 for securing'theinneradjacent walls of the case, butit will be understoodthat anydesired number may be used.

I prefer to equip .the central portion of-the case 10 on the interior thereof With a Wing nut 23 engageable with a threaded stud 24 for the purpose of securing within the case-of the fouiutable legs 25 when they arelaid therein in nested,position. If desired, a clamp may-be employed with the nut .23 forengaging'the-nested legs 25 and securing them in. position.

Each of the legs .25 is preferably formed of .an angle piece having the twofianges thereof formingsubstantially a V .in cross section. -I prefertohave-the anglestapering slightly,:as indicated moreclearly-inFigs. 4 and 5. Also, I prefer to provide.the=legs attheir innertends with notches 26, as shown more clearlyinEigJS. Near 'the'upper end of each leg 25 Iprovide an indentation ,2-7 .to-eooperate withthelocking screw.28, as will be later'described.

.In ;the t.op portionof thetabletnearteach corner, I provideaplatformorbracket 29 having arecesstherein for receiving the upper portiontofzthe leg .25. Thenotchzportion.26 .of .the-legbears against a 'portion of theplatform 2 9,asindicatedat 30in Fig. 4. iThelplatform 29 is .provided with vflanges Miami :32, which are preferably secured by spotwelding to the table :top section 12 thereabove.

Spaeedalong the side wall 1.0a ,or 1510 below the'panel 12, is a triangular support 133;,as shown more clearly in Fig. .5, theqopening 34in the piece33being such asto engage the-flanges ofthe-legand-to.brace-the same. A standard '35 ,extends through -,th,e platform and thence upwardly and is provided with a right angle flange 36, which may be spotwelded to the triangular piece 33.

Secured to the standard 36 is a nut 37 receiving the screw 28, which is provided with a wing handle 38.

In the operation of the table case, the legs 25 may be brought with their V portions in nested relation and secured by the wing nut 23 along one side of the case. Stools or other articles may be folded within the case and carried to the desired destination. The case may then be opened and the articles removed, the nested legs 25 being released also. The table top portions 10 and 11 may be placed upon the ground in open position and latched in this position by rotating the latch bars to the positions shown in Figs. 6 and 7. The legs may be separately placed in position by inserting the ends thereof into the table corners, as illustrated in Fig. 4. The upper notched end of each leg fits within the recess of the platform 29, and the screw 28 is then advanced to bring the point thereof into engagement with the indentation 27 of the leg 25. By this means, each leg is securely and rigidly anchored within the table corner. The indentation 27 prevents outer movement of the leg and each leg is confined between the angles of the parts 34 and 29. When the table is secured as described in the position shown in Fig. 2, it is found that an extremely rigid structure is provided. At the same time, the table may be lifted or handled as a single rigid unit. When it is desired to form a case again, the screws 28 are loosened and the legs removed, placed in nested position, and secured Within the narrow area, as illustrated in Fig. 3, with the wing nut anchoring the nested legs against one side of the case. The folding stools may then be collapsed and placed within the case, together with cutlery or other material to be carried, and the case locked in the position illustrated in Fig. 1.

While I prefer to employ legs having angular sides, it will be understood that legs of other shapes may be efiectively employed; further, instead of the wing screw and nut structure, fastening means such as toggle clamps and other similar devices may be employed.

If desired, rubber tips 39 may be provided for the ends of the legs 25. The rubber tips are preferably triangular in cross section and form sleeves receiving the outer ends of the metal legs 25 for frictional engagement therewith.

While, in the foregoing specification, I have shown a specific structure in considerable detail for the purpose of illustrating the invention, it will be understood that such details of structure may be varied Widely by those skilled in the art without departing from the spirit of my invention.
