(CI. 45-11) This invention relates to convertible bed tables. It is an object of my invention to provide a convertible table, of a sort which may be used by a person in bed; said table being adapted to be used either in a horizontal position, to hold dishes, or in an inclined position, to hold a book for reading, or as a writing desk, etc.

Another object is to provide means whereby my table may be interchangeably used as described above.

Other objects will appear as the description proceeds.

My invention will best be understood by referring to the following description, taken in conjunction with the accompanying drawings, in

which like reference characters denote like elements throughout, and in which:

Fig. 1 is a bottom plan view of the table;

Fig. 2 is a side elevation of the table when being used flat;

Fig. 3 is a side elevation of the table being used as a writing desk;

Fig. 4 is an enlarged detail view of the locking mechanism for the feet, to be used when the table is flat;

Fig. 5 is an enlarged bottom plan view, partly in section, of the locking mechanism for the feet when folded;

Fig. 6 shows a longitudinal section of one of the extensible legs permitting the use of the table as a writing desk;

Fig. 7 is a section on line A-A of Fig. 1, showing the ledge in position to hold a book or other object;

Fig. 8 is a section on line A-A of Fig. 1, showing the ledge in position adapted to be used as a writing desk;

Fig. 9 is a similar view showing the ledge'in its inoperative position.

According to the embodiment of my invention shown in the drawings, the table 1, which may be preferably of wood, in order that it might be light, is of generally rectangular shape, being of greater width than length, and is supplied on its under side with two groups of legs. The first group comprises four legs 2, of equal length, being preferably of wood and located one at each of the four corners. The second group-comprises two legs 3 placed at the two corners on one long side. The

legs

2 and 3 are all hinged at 4 permitting them to be folded inwardly against the bottom of the table.

On the longitudinal side opposite legs 3, the

- table 1 has an indentation or cut-away portion forming thus two prolongations 5-5. These prolongations serve first, as arm rests when the table is horizontal, the four legs 2 being opened and legs 3 folded, as is represented in Fig. 2; and serve secondly, as legs when the table is used as a writing desk, the two legs 3 opened and legs 2 folded, as shown in Fig. 3.

In order to give the table a variable inclination when it is used as a writing desk, the legs 3 are extensible. To this end, they are formed, as shown in Fig. 6, of two telescopic tubes 3a and. 3b of wood or metal of rectangular, round or other convenient cross section. A locking mechanism comprising a spur or pin 6, fixed within the interior of tube 31) by means of a spring 7, which tends to push it externally thru a hole in the wall of tube 3b, permits the immobilization of the two tubes, to produce any given length, by entering into one of the spaced holes 8, pierced in external tube 3a.

The four legs 2, of fixed length, as well as the two extensible legs 3, are provided with a mechanism for locking them in the folded position. As shown in Fig. 5, the locking of each leg in the folded position is secured by means of apin 9, mounted on a fiat spring 10,-lodged in a cavity 11 in a block of wood 12 (Figs. 1 and 5 the said cavity 11 being closed laterally by a metal plate 13, which is pierced with a hole permitting the pin to extend outwardly. This pin is adapted to lodge in a cavity formed by a I spherical metal cap mounted in a plate 14 on the adjacent side of leg 2, or in tube 3a of leg 3.

In Fig. 4 is represented one form of means for immobilizing legs 2 in the open position; the same mechanism being shown on a slightly smaller scale in Figs. 1, 2 and-3. As shown, an arm 15 is pivotally mounted at 16 on the side of the leg. This arm bears a longitudinal slot 17 in which slides a pin 18, carried on an angle iron 19, fixed on the bottom of the table, A spring 20, fixed on the arm and bearing against pin 18, pushesthe latter against the upper edge 21 of the groove 17. This edge has, at its extremity farthest from the leg a notch 22 in which, under the action of spring 20, pin 18 lodges when the leg is opened, thuslocking the leg in open position.

The table is provided with a ledge disposed at the edge of the indentation and projecting above the upper face of the table in a manner to maintain upon the table, when used as a writing desk, an object such as a book, writing paper, etc.

As shown in Figs. 1, 7, 8, and 9, this ledge comprises an L-shaped piece 23, preferably of metal, fixed by two fiat springs 24'and 25 to a rod 26,

which slides in

grooves

27 and 28 formed in

cleats

29 and 30. These cleats may be made as long as the table in order to reinforce it, as well as to serve as guides for bar 26.

Ledge 23 bears on its interior a projection 31 of a sort that the ledge can occupy three different positions to be indicated later; the projection can be made flush with the table (Fig 7) the ledge then has a height corresponding to the lateral face of element 23, and can be used to hold a book, for

example. In Fig. 8, projection 31 rests upon the' bottom of the table, and the height of the ledge is diminished with respect to Fig. '7 by its thickness. The ledge is then in a suitable position for Writing, etc. Finally, in Fig. 9, the ledge is moved completely out of the way.

These three positions are possible due to the elasticity of the

fiat springs

24 and 25, and the sliding of bar 26 in

grooves

27 and 28.

Clips

32 and 33, rotatable about the same axis 34,'are' me tallic plates and serve to immobilize or in other words hold the ledge in the three indicated positions. Of course, these clips could be replaced by any desired mechanism; in the same manner the ledge mightbe merely a projection, without the extra projection or step 31. V

In order to hold the object supported by the ledge, especially in the case of a book, one or preferably two bands 35 (Figs. 1 and '7) pass thru slots 36 and 3'7 cut into ledge 23 and projection 31, pass across the table and may be made to pass, for example, over the first and the last page of the book, which is in this manner held perfectly, while permitting the reading of all the pages.

While I have, in describing an embodiment of my invention, shown and described certain details of' construction, it is to be understood that these are not to be considered as limiting, but are illustrative only.
