Claims.

My invention relates to a knock-down table which may be separated into its component elements for the purpose of packing such elements into a compact unit for facility of transportation and to be reassembled at the place of its intended use with a minimum of effort and mechanical ingenuity required of the user.

A particular object of the invention is to provide a table of the knock-down type with component elements of simple construction, light in weight and of low cost to manufacture. A more particular object of the invention is to provide a table having two frame elements to which are pivotally secured the leg portions of the table and to which frame elements the member designed to serve as the top of the table when the latter is erected may be securely and easily fastened.

A still further object of the .invention is to provide a knock-down table with a top having a. plurality of slats supporting a flexible material which is to comprise the table surface and to have such top structure positioned upon the frame construction rigidly when the table is erected.

A novel feature of my invention consists in the provision of a novel means of securing the table top structure to the frame elements of the table to each of which are pivotally secured two legs of the table. A further novel feature of my invention consists in providing each of the two side frames of the table with a pair of leg members pivotally secured thereto and which may be folded into position so as to be contained within the peripheral confines of the side frame so that the entire table structure, with the two side frames collapsed and the top structure in rolled-up condition may form a compact package to facilitate the transportation of the structure.

In the accompanying drawings illustrating a specific embodiment of my invention, Fig. l is a perspective view of my novel knock-down table with a portion of the top covering broken away; Fig. 2 shows the entire structure rolled into a compact package for transportation; Fig. 3 is a bottom view of the assembled table structure; Fig. 4 is a bottom plan view of the table top showing the bracing elements thereof which are adapted to secure the top structure in rigid position to the frame elements; Fig. 5 is a reverse plan view of one side of the top structure showing one of the channel bars secured thereto and adapted to cooperatively engage the side frames of the table; Fig. 6 is a bottom view of one of the frame elements with the two table legs pivoted thereon folded against the same; Fig. 7 is aside view, part- 1y broken away, of one of the frame elements; Fig. 8 is a fragmentary plan view of the top structure with portions thereof broken away so as to show the means for efiecting the cooperative engagement of said top structure with the side frame 5 elements of the table; and Fig. 9 is a side view of the top structure in section.

Referring more particularly to the drawings, in which similar reference characters identify similar parts in the several views, ii! designates 10 the table as erected and ready for use-and including a pair of frame elements ll illustrated in enlarged detail in Figs. 6 and 7. Each of such frame elements comprises a channelled bar I2, preferably made of sheet metal, at each end of which is secured an elbow l3, one leg of which straddles the frame element [2, being secured thereto by rivet M, the other leg of such elbow having a channelled configuration such as clear- 1y illustrated in Fig. 6, the channel being U- shaped, having a main slot I5 and slots l6--l6 disposed at right angles to said main slot and forming continuations thereof. Within the channel of the side frame element [2, contiguous with the end thereof upon which is mounted one of the elbows l 3 is a block I1, with two sides of which a bent strip [8 contacts, the free end of such strip being reversed to form a U with one of the portions thereof in contact with the block l1, so as to have pass therethrough the rivet l4. Pivotally secured upon the rivet I4 is a preferably hollow metal bar I9 which, when pivoted about the rivet l4, serves as one of the legs of the table.

.The other end of the frame element is similarly constructed, having leg 2|] pivoted thereon. As will be noted from Fig. 6, the rivets l4 and therefore the pivotal points of the two legs l9 and 20 are oifset from each other so that when such legs are folded upon the frame section they will occupy positions within the confines thereof contiguous to each other so that in the course of erecting the table first the leg portion l9 may be turned about the pivot in the direction of the arrow A and after such leg has been brought to a position at right angles to the frame element, the leg 20 may be pivoted about its pivot point, in the direction of the arrow B, until such leg portion is at right angles to the frame element.

Provided upon the side of the frame section is a plate 2! against which the leg 20 is adapted to abut and which serves to retain such leg within the confines of the peripheral area of such frame section.

Secured to blocks 2222 within the channels of the frame elements, one of such blocks being positions at right angles to the side frame sections of the table.

The top structure for my novelknock-down table comprises a plurality of slats 36,'preferably made of wood and disposed in parallel relation to each other, to which is secured by any suitable fastening means 3| a flexible surface material 32. such as leather or cloth. For supporting the,

edges of the surface material, I find it advisable to connect the end surfaces of the slats 30 with a cord 33 secured to the two endslats by tacks 34'. The edges of the flexible material parallel to the slats 30 are turned over so as to secure within such ends a bar 34, the material being secured to such bar by any suitable fastening means 35, such fastening means also serving to secure the bar 34 to a channel strip 36 having its ends 31 extending beyond the limits of the bar 34. Preferably the ends 31 are chamfered as shown at 38 in Fig. 8. v

Within'the channelled bar 36 and at approximately one-third of the length thereof, is positioned ablock 39 upon the portions of which disposed in the lower half of the channel (Fig. 5)

. is pivotally secured by means of rivet 40 the brace element 4 I. A similar block 42 is positioned within the channel at a point about two-thirds of its length upon the portion of which disposed in the, upper half of the channel is pivotally mounted by means of rivet d3 the brace element 34. Each of the

brace elements

41 and 44 is provided near its end with a slot 45. and a sleeve 46 adapted to ride overthe'brace element so as to override the slot 45 when the latter has engaged pin 41 extending from theleg of the table with which the brace element is adapted to 00- operate. As shown in Fig. 6, a slot 48 is provided in the side of the leg I9to: accommodate the pin 41 when such leg is in position upon the frame element I2. 7 V

As will be noted froman-examination of Fig. 4, the structure just described-is also provided. upon the other side of the table top;

In assembling my novel table into the erected condition thereof, one ofthe side frames II, I2 is brought to the horizontal position, the legs I9 and 20 being pivoted therefrom. untilthey extend approximately in vertical position,.the bracing elements 23, 21 andi24, 28 being brought'to their lineal positions so;as to secure the legs rigidly in a position in which they depend from other channel bar 36 ofthe'top structure is simi-- larly brought into cooperative engagement; with the elbow I3 on the other'end oftheframe element, when the second frame element is erected and brought into approximate.- relationship: with the top section so that the, remaining ends of the bars 36 may be made to telescopically engage the elbows I3 on said second frame element.

For completing the rigid mounting of the table, the brace members 4|, 44 are swung outwardly from the channel elements 36 of the top section, the ends thereof being made to engage the legs is and 26 by means of the slots 45 cooperating with the pins 41 extending from the legs. In order to secure such bracing members, the sleeves 46 are slid along such brace members it) until they cover the slots 45 with the pins extending from the legs passing through the slotted openings within such sleeves.

v The table when thus erected is rigid and has a smooth surface which, however, is sufficiently 15 rigid to retain any object placed upon the table top and. is sufliciently resilient to provide the desirable. surface for playing a card game for which my novel table is particularly suited.

In disassembling the table the operations here- 9 inabove described for erecting the-same are carried out in reverse order, the table top being capable of being rolled up into the condition illustrated in 'Fig. 2' with the two frame elements contained within the rolled up top. The 25 entire structure may be thus easily fastened together by any suitable means such as pieces of cord, and may thus be shipped or transported in an automobile or similar conveyance.
