'K-NocicoowN TABLE.

Specification of Letters Patent. Patented J fi 27 1916 Animation filed March 28, 1914. Serial No. 827,802.

'To all whom it may concern; Be it known that I, DAVID BLocK, a citizen of the United States,.residing at Chi-- cago, in the county of Cook and. State of Illinois, have invented certain new and useful Improvements in Knockdown Tables, of

which the following is a specification.

' This invention relates to shdet metaltables,

and more particularly to tables of this class in which the several parts which consti.

'tute thetable can be easily and readily dismembered so that the entire table'may be encompassed in a small compact space.

A further object of the invention is to provide detachable legs which are releasably locked to the table top.

For the attainment of-these ends and the accomplishment of other new and useful objects, as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts generally shown in the accompanying drawings and describedin the specification, but more particularly pointed out in. the appended claims.

In the drawings, Figure 1 is a perspective of a table constructed in accordance with the principles of my invention; Fig. 2 is a detail view of the le locking device taken on the line '2'2 of F g. 8; Fig. 3 is a detail viewofthe leg locking device taken on the line 3-3 of Fig. 2 ;,Fig. 4 is a sectional view showing the shelf fastening taken on, the line 44 of Fig. 5-; Fig. 5 is a sectional view of the same taken on the line 5+5 of Fig. 4, and Fig.6 is a perspective 'ofone of the spring locking clips.

This invention relates to a collapsible tabi? Referring more particularly to the drawings, the top comprises. sheet'metal sides 2 and. ends 3 with the edges 4 and 5, respec- I tively, bent inwardly atthe lower edge, overlap ed and secured together as by means. of

' a rivet 6, the sides and ends'being connected in any suitable manner, as for example,

by a connection 7 (see Fig. 3) at the junction corners thereof. The surface for the table top is preferably formed from a single sheet of material 8 with an upwardly extending ridge 9 about the edges which is folded over and secured to the sides and ends 2 and 3 by pressing the folded edges 9 .firmly against the sides and ends, or any other suitable manner, leaving a projection 10 on the outside of the sides and ends. This is the preferred construction of the top although, of course, other constructions may be'employed. It will be seen that the upper surface is recessed, forming a kind of a pan, and that the top is open from the bot tom forming a considerable recess for containing the legs when the table is in knockdown position.

Each leg comprises an angular member 11 formed at the top with hooks 12 which are adapted to engage over the folded edges 9 at thecorner where they abut. vThe extremi ties of the sidesof the angularmember 11 are formed with a ridge 12", as shown more clearly in Figs. 3 and 4, which terminates below the hooks 12 which is adapted to en-' gage belowlthe projection 10 formed by the folded edges 9 of the top. 'For a distance from the top of each leg equal to the height I of the sides and ends there is no reinforcement other than the ridge 12, as shown more clearly in Fig. 3, but commencing immediately below the side and end is a reinforce 13 the edges of which are clamped in the ridges This reinforce is preferably in two pieces in each leg, ears 14 being bent in wardly therefrom at their junction point which are perforated to form a support for a a shelf 15. The extremity of each leg is formed with a" bottom bend 16 to form a bearing surface and with-a bend 17 at'the inner corners. =gthereof which serve to' hold the lower force-mdre securely in position and alsdprevent corners at these points.

In order to lock each leg in .connection with the table top a spring clip 18 (see'Fig. 6) is provided with: the extremities 19 and 20 bent substantially parallel to each other and at an angle toj'an intermediate portion between them; one extremity 19 being sub.-

stantially less in-length than the other extremity 20. Inlocking each leg in position the shorter extremity 19 of thelocking clip is placed in engagement with. the upper edge of the reinforce 13, the hooks 12 are placed in engagement Wlth the bent edges 9 at the junction corner, the leg being inclined outwardly so that the clip 18 is free time being beneath the bent-in edges 4 and of the side and end 2 and 3 but out of en- I gagement therewith. The clip is then moved into engagement with the bent edges 4 and 5, the extremity 20 of the clip engaging each bent edge at an angle thereto, as shown more clearly in Fig. 3, and the angle of the extremity 20 being such that this extremitymust be pressed resiliently over the edges 4 and 5 thereby forcing the table top up wardly so that the hooks '12 engage the upper ridge firmly, the extremities of the ridges 12 engage beneath the projections and the upper edge of the reinforce 13 supports the table top by the engagement of the body-of the clip 18 with both the over-lapped turned-in edges 4 and 5 of the side and end members and the upper extremity of the reinforce.

The shelf 15 is preferably formed with bearing edges 21 turned inwardly at the bottom and the corners are cut ofi at an angle corresponding to the size of the legs so that the shelf will be contained in the space inside of the legs, the shelf being provided with perforations corresponding with the ears 14 through which 'a fastening device 22 is inserted to hold the shelf firmly in place,'thus aiding in reinforcing the table, in properly spacing the legs apart and forman additional surface or shelf.

Tn collapsing the table the assembling operations are reversed and the legs are of the size to be contained in the space which opens fromthe lower side of the top, preferably being of such a length that they must be disposed diagonally therein whereupon they are retained in position by the inwardly bent edges 4 and 5. The shelf 15 being slightly smaller than the table top is adapted to be received in therecesse d upper surface.

With this construction the entire table, including the legs, is composed of sheet metal which makes the structure light and strong, the strength being increased in the case'of the legs by the reinforce and the strength being added to all the parts by bending the edges thereof. The edges are also bent for the purpose of obviating the shar out edges of the metal. I
