7.70 all wzom t may' concern:

'Be it known that I, MICHAEL KorUN, a citizen of @Zeche-Slovakia, residing at New Geneva, in the county of Fayette and State of Pennsylvania, have invented certain' new and useful Improvements in Collapsible Tables and. Chairs, of which the following is a specification.

The present invention consists of a coll0 lapsible table and chairV and is designed as an improvement` over my United States Letters Patent Numberv 1,380,153 patented May 31, 1921. l

A Objects of the present invention are to provide a combined table and chair, or series of chairs, all of which may be conveniently folded so as to adapt the same for use by automobiliste, campers or the like;

to provide -a collapsible table and chairl which may be quickly set up for use and expeditiously collapsed at the option of the user; to provide a collapsible table and chair characterized by a maximum rigidity; to provide a relatively rigid table top; and to provide av device o-f this character which may be manufactured at a relatively small cost. i v

The above andlother objects of this invention will be more fully understood from nection with the accompanying drawings where1n2- y y Fig, 1 1s a verticalsectional view of a de- .vention showing the table and chair set up; Fig. 2 is a fragmentary plan view of. a

table top constructed in accordance with thisv l conguration.

the following description of the present pref ferred form of the invention taken in con` vice constructed in accordance with this in- Fig. 3 lis a vertical sectional view of the taining section showing its supportingrng associated. therewith.

The device Aof this invention `consists of a main or outer supporting section S preferably made `of metal vand of' cylindrical i One end of this section is closed, as indicated at 9, and thel opposite end open. The open end is equipped with a cap or closure l10 which may'also be used in the capacity of `a drinking cup or cooking utensil. The section 8 has a slot 11 formed 65 ytherein and extending. vertically therethrough.` The lower end of, this slot tery minatesshort of thev closed 'end 9 of this section while the other end terminates approximately midway the ends of the section in right vangled slot 12. Y, .p l y y Telescopically mounted within the main section S'isan auxiliary section 13 which.

.serves in theA capacity of "a table top containing tube and is preferably of cylindrical conti gurationyaud relatively smaller than the main section 8 so that tlhe outer` periphery of the auxiliarysection 'will be spaced' from the inner periphery of'the `main section 8. One? end of the auxiliary section` is closed as indicated -at 14;, i, while the opposite end is open. The lower closed end of said yauxiliary sectionxhas an eye 15 formed thereon inv which a split" holding" ring 16 is mounted..v One .terminal of 85 this ring is turned outwardly at right angles tof provide a linger piece 1.7. `This is used vfor elevating the auxiliary section 13y in the main section 8 andis engageable in the rig-ht angledy portion 12 of the slot 11 in order to 90 support-the Vauxiliary-section in thev desired position of elevation in the main section.

A. coil spring 18 is mounted on the closed p lend 14 of the auxiliary section 13 and'has superimposed `thereon acore 19. This core is preferably of tubular coniiguration` and y is equipped with an insertable lock QQ'wlnch carries plurality of pivotally mounted arms 21 which constitute supporting members forv a flexible table top per se 22. 4Flach 100` olf said arms 2l is preferably Vlornied l'roin a inet-al sheet having one end thereoiE pivotally engaged with the insert 20. Upon roterence to Fig. l ot the drawings. it will be noted that the bloclr 20 is arranged beneath theclosed upper end ot the core 19, openines being provided through which said arms extend. Each arm the lateral marereovf bent inwardly at right anfrles to provide z Q4 as .shown to advan in 4, rThis way in each ariu is equipped with a sprin` The outer terminal oi each arm is bent at i" it angles as indicated at 26. and is engaged in any suitable manner wi'h the table top per se 22, the margin ot the latter preterably depending below the tree margins et the right angled portions 526, as shown in Fig. l..

Slidably mounted on 'the auxiliary section i3 is a collar 27 which has rislA upwardly therefrom hinged struts 28 the outer end oit each ot which latter has right angled i. vatv pinth Q9 `termed thereon. rlhe pintles ot each arm are reciproc-ally mounted in the Away 24 ot one ot the arms and is normally urged o Atwardlv toward the right angled end 26 of its arin by the spring 25. These `struts will augment retention of the table top in an open or set up position.

ln order to add to the rigidity of the table top' suitable supporting ribs 30 are provided. These ribs have the'. ends thereof pivotally connected to the arms 21. A pair ot these ribs is arranged between each pair ot arms and has the proximate ends thereof pivotally "connected as indicated at 3l. li/lcvement of these ribs is limited by an extension 32 formed on one ot the ribs and overlapping the proximate endy ot the ad- Iiacent -rib at the pivot point 3l. thereof. These ribs, when set up torce' the arms apart with obvious results. When it is desired to set up the table the cap l0 is removed and the auxiliary section 1 elevated through the instrumen- -tality ot' the tinger piece l? in .a manner heretofore described. After said section hasbeen elevatedvin this manner, a hasp which is rarried by one ot the arms?v and engaged with openings 33 inthe section 13, ,is disengaged. This permits the spring 18, "which has been heretofore under compression, to expand with the result that the core 19 is projected upwardly in the auxiliary section i3. Upward movement ofthe core is limited in view of lugs 34 which are harmed by bending portions ot the upper lterminal of the auxiliary section inwardly at right angles to overhang the core 19.

4in. annulus 35 is slidaloly mounted on the outer periphery ot the main section 8 and has pivotally mounted. thereon one end of each of a series ci' supporting legs 36. The

opposite ends of these legs are bent at right angles to provide feet 3? for engagement inet-oso with the ground or other supporting body. lt desired each ot said legs may be provided with aloop, such as the loop 37 shown on one ci the legs in Fig. l, through which a seat supporting standard 38 is slidably mounted. The lower end ot the standard is preferably pivotally mounted adjacent the closed end et the main section 8 while the opposite end terminates in liurcations Si). These furcations are joined by a cross bar l40 which is pivotally mounted beneath a plate 4l. The plate 4l has a run way 42 termed therein in which one end ot a pedestal 43 is slidably mounted. The opposite end ot said pedestal isengageable with the ground or other supporting object. The pedestal 43 extends between the furcations 39 and are pivotally connected thereto. A

seat 44 is carried by the plate 41 and may indicated at 47, and engaged in the vertex ot the turcations 39.

The seat structure may be collapsed b y first disengaging the retaining rod 45 from the turcajtions 39 following which the annulus 35 is moved upwardly on the section 8 and the upper end ot the pedestal 43 perinitted to slide Voutwardly to the endet the run way 42 after which the seat'44 gravitates downwardly. rlhe entire seat structure may in this way be l'olded iiat against the outer periphery of the mainsection 8.

./z-ilthough l have above described what new seems to be the preferred Jform of my ii'm-.intion it is nevertheless to be understood that various changes may be made the-rein especially in the details of construction,`

proportion and arrangement of parts within the scopev ott the claims hereto appended. By preference. hoivei'cr7 the device is made relatively small and ot cylindrical conliguration so as to permit storage of same beneath an automobile seat or in any other relatively small compartment.

lWhat is claimed is l. A device as speciiied including a main supporting section equipped with a telescopic table top containing section, a hasp carried near the margin ot `the table top and engaged with its containing section, near the upper terminal ot the latter, to normally hold the table top within said containing section and means to automatically elevate the table top when said hasp is released. l

2. El device as speeilied including a main supporting section equipped with a teleu scopic table top containing section, means to f said table top section to limit upward move-` ment of said table top.

A device of the character described iii-- cluding telescoping cylindrical sections one of which is equipped With a spring pressed table top, armscarried by ysaid table top and equipped with springs, and struts pvotally carried by one of said sections and movable in said arms under influence of the springs to hold said table top inv a rigid position. y' f y In testimony whereof I aiiix my name.

MICHAEL KOTUN.
