4 claims. (C1. .4s-1013.) Y

Round or oval tables of a known kind which can be enlarged on all sides are of a very complicated construction so that they have not been generally adopted. This applies more particularly to known tables of the kind in which hingedtogether segment-shaped enlarging parts are provided, which when not in use are folded one over the other to form a pile and are housed in the space below the table top.v For enabling the segment-shaped enlarging pieces to be spread out it has been proposed to divide the top part of the frame into sections and to' make these sections capable of being hinged downwards. The subdivision of the top part of the frame into a number of parts and the fact that the said parts of the frame must be unlocked and locked again both renders the manipulation of the table dimcult and renders the structure insecure. For this reason in the known tables each section of the top part of the frame is provided with a hinged sub-section, which serves as a supporting rail i'or the enlarging pieces. Furthermore as the xed table top covers the enlarging mechanism the difliculties in operating the table are considerably increased.

The same applies to table constructionsy of the above kind in which both the table top and the top part of the frame are xed. In such constructions complicated bow-shaped arrangements are provided, which enable the enlarging segments to be passed round the upper part of the frame. Y

All these disadvantages are overcome by the present invention through the table top being :arranged to move upwards for enabling the enlarging segments to be removed from the space within the top part of the frame to the outside and vice versa. The top part of the frame itseli'll remains stationary and can provide very elllcient support for the enlarging segments.

. The invention can be embodied in various constructional forms. Thus the table top maybe composed of two halves hinged together and the pile of segments belonging to one half of the jtable top may be hinged to the top part of the frame in such a manner that on the half of the table top being hinged up, the pile of segments can be hinged out of the inoperative to the operative position and vice versa. This arrangement l has the further advantage that the hinging out'- wards of the enlarging elements may take place as it were automatically. For this it is only necessary to provide between the half of the table top and the pile of segments belonging to it a exible. pivotal or other connection, which makes the movement'of the half table top and the pile of segments interdependent.

The invention is clearly illustrated in the accompanying drawing, in which:

Fig. 1 is a plan view of a table with a twopart table top,

Fig. 2 is aside view of the upper part of the table according to Fig. 1. partly in section.

In the table according to Figs. 1 and 2, the table top is divided into two halves;` a and b which are hinged together. The enlarging parts are in the form of segments c, three segments being in each case combined to form a unit, so that one group of segments is composed of the segments c1, c, c and the other group of the segments C4, c, c". The segments of a group are connected together by hinges d and e so that in each case three segments can be superposed to form a pile (Fig. 2). Each pile of segments is supported by two supporting arms f which are connected to the top part h of the table frame by a hinge joint g. In this connection it is to be noted that the inner edge of the frame h is constructed in stepped formation the hinges g being connected to the free edges of the intermediate step so that when the arms f are in inoperative position they are supported on, the lower step and when in an operative position are supported on the intermediate step passing through a groove in the upper edge of the frame. This arrangement permits the sections a and b to also engage the upper edge of the frame when the arms are arranged in an opposite position. Fig. 2 shows how the pile of segments is brought from the. inoperative into the operative position and vice versa. The table top half a is raised. By means of a exible connection i, for instance a piece of girthing, the pile of segments is also raised. Only a small amount of pressure is then required for hinging over the pile of segments to the outside, the half a of the table top returning into its normal position. The pile of segments is then spread out, so that the segments rest closely against the periphery of the half a of the table top as shown in full lines in Fig. 1. The broken lines in Fig. 1 indicate how the pile of segments is housed inthe space within the top part of the frame. A bar :i is preferably provided in the top part of the table frame, for supporting the pile of segments. Suitable locking devices may of course be provided between the two groups of segments for obtaining a closed rigid enlarged Dart.

It is believed in view of the foregoing that a further detailed description of the operation of the invention is unnecessary. Likewise it is believed that the advantages of the invention will be readily apparent.

What I claim is:

1. A table including an open supporting frame, a top on the frame including a pair of sections hinged with respect to each other and each adapted for vertical swinging movement relative 2. A table as claimed in claim 1, wherein lex.

ible connection means are providedbetween each top section and the outermost enlarging me1riber onthe adjacent supporting arm for the purpose of causing an upward swinging motion and partial raising of said arm With the pile of enlarging members thereon upon the raising of each top section.

3. A table as claimed in claim 1, wherein the inner edge of the frame at the point Where the arms are pivoted are constructed in stepped formation, the lower and intermediate steps acting to support the arms when they are respectively in an inoperative and operative position.

4. A table as claimed in claim 1, wherein supporting bars are arranged across the table frame near the lower edge for supporting the top enlarging members when the latter are in inoperative position to ensure of their remaining in pile formation when in such position.
