This is of great importance when it is desired to mount for instance a shelf 1 3 for newspapers between the legs of the table, as is shown in Fig. l, for if the legs 2 in such a construction have to be moved a considerable distance towards or away from each other for compensating the drying of the wood, it would be impossible or at any rate very difiilcult to fasten the newspaper shelf IS in such a way as to permit the necessary displacement of the legs without the shelf being loosely secured to the legs in some adjusted position.

The inventive idea defined by the claims can be realized in many ways other than that shown in Figs. 1 to 3. Three different alternatives are shown byway of example in Figs. 4 to 7.

The embodiment according to Fig. 4 substantially corresponds to that according to Figs. 1 to 3, and Fig. 4 merely serves the purpose of illustrating how it is possible to provide a sufficiently large stop face 28 to bear against the underneath side of the border member 29 and also the corner block 30 when the legs 3! are slender and consequently the tenon 32 provided with inclined surfaces for co-operation with the corner block 38 has to be made approximately as thick as the legs for reasons of solidity. In the embodiment according to Fig. 4 the stop face 28 is formed on a loose plate 33 passed over the tenon 32 and bears against a small shoulder 34 on the leg 3|, from which the tenon 32 projects approximately centrally.

In the embodiments according to Figs. 1 to 4 the hole 35 for the rod [4 and 25, respectively, in the corner block 4 or 30 and in the angle piece 26, respectively, is oblong or formed with a sufiiciently large diameter in order that the rod l4 and 25, respectively, may participate in the movement of the leg 2, l1 and 3|, respectively, when said leg is lifted towards the table-top on fastening it to the same.

It should be pointed out especially that it is not absolutely necessary to letthe stop face 6 i3 and 28, respectively, surround the tenon '1, l9 and 32, respectively, on all sides, as shown in the embodiments according to Figs. 1 to 4.

, Fig. 5 illustrates an embodiment wherein the stop face 36 of the leg 31 is to be foundonly beneath the border member 39 of a table-top 38, which member is provided in this embodiment with inclined surfaces which in vertical section are of a toothed appearance, for co-operation with corresponding surfaces on the tenon 40 of the leg 37, Fig. 5 also shows a fastening means other than a threaded spindle. This fastening means consists of a wedge 4i driven in between the side of the leg 31 remote from the border member 33 and block 42 secured to the underneath side of the table-top 38. The wedge 4! is retained in drivenin position by means of a screw 43 passing freely through an oblong hole 44 in the wedge 4|, so that after loosening of the screw 43 the wedge can be driven in a further amount for compensating a possible drying out of the wood.

In Figs. 6 and 7 the invention is applied to a table comprising a tabletop 45, two plate-shaped legs 46 and a transverse member 4'! connecting the legs 46. This embodiment shows by way of example that the upper ends of the legs do not need to beintroduced in. recesses for attaching them, a'sis the case in thej other embodiments shown in the drawings. The upper end of each leg 46 is formed in the same manner as that of the leg shown in Fig. 5, for cooperation with a securing member 48 fixed to the underneath side of the table-top 45. The leg 46 is pressed against the member 48 bya screw device corresponding in principle tothat shown in Fig. 2.

As is evident, the invention may be realized in various ways, for which reason it must not be considered as limited solely to the embodiments shown and described. It should be observed especially that the invention may be applied to other pieces of furniture with legs than tables, e.'g. chairs, sofas'and cupboards. Instead of fastening each leg individually, it is naturally possible to connect the legs in pairs to a unit or subassembly that is fastened in accordance with the invention. Therefore, the expression leg means is used throughout this specification and. the appended claims to refer to both single legs; and such 'subassemblies consisting of two (ormore) legs connected to a unit. Itshould be, pointed out also that the stop faces 6, 28 and 35,, respectively, forming angles with the inclined co-- operating surfaces of the body portion of the piece.- of furniture and arranged on the respective leg orpair of legs can be arranged in a manner otherthan that shown. For instance, they can be ar-- arranged on the end of the respective leg for bearing againste. g. the underneath side of the: table-top or the like.
