Claims.

This invention relates to tables. In rooms where space is restricted it is very desirable that a table in such room may be operated so as to take up a relatively small amount of space whenr Y ju;n serve the purpose of a corner stand or desk.

My invention is concerned with producing a Vtable of the character described which can be readily changed from one condition to the other and which, when serving either as a table or a "corner desk, will be strong and sturdy and fully capable of sustaining the service to which it *isv subjected. A further object of the invention is to provide a novel construction for the purposes stated, which is practical for economical and commercial production. v

The invention may be understood from the following description of a preferred embodiment thereof, taken in connection with the accompanying drawings, in which: Fig. 1 is a perspective View showing the'structure when it has been retracted to its smaller space occupying position and in which it may be located at a corner of a room.

, Fig. 2 is a plan view of the construction shown in Fig. 1 at the time of the completion of the first steps in converting the structure into a table having a horizontal circular top.

Fig. 3 is an under plan view. of the structure when it has been completelyA converted into a table. v Fig. 4 is a fragmentary Vertical section taken on a vertical plane substantially midway between the sides of Fig. 1. p

Fig. 5 is a fragmentary somewhat enlarged elevation at the rear of the left hand side of Fig. l.

Fig. 6 is a fragmentary detail in elevation illustrating the hinged connection of bars to which sectors of the table top are hingedly connected.

' Fig. '7 is a fragmentary vertical section substan-l tially 0n a plane corresponding to line lof Fig. 1, and

Fig. 8 is a fragmentary vertical section substantially on' the plane of line 8-8 of Fig. 3.

Like reference characters refer to like parts in the different gures of the drawings.

In the construction shown are three vertical supporting legs I, 2 and 3. The legs l and '2,` which may be termed outer legs, are connected adjacent their upper ends by a curved rail or apron il. Bars 5 extend between each of the legs I and '2 and the inner leg 3 a short distance below the upper ends of said legs. A flat bar 6 extends from the inner leg 3 outwardly to substantially the middle point of the curved apron 4 (Fig. 8). The legs l, 24 and 3, the

bars

5 and 6 and the apron fl, are rigidly secured together, making a rigid frame.

' A horizontal sector l of a top is located over s the upper ends of the legs I, 2 and 3 and over the upper edge of the apron d, and is permanently secured thereto. Such sector 1 supplies onequarter of the complete table top. Two sectors il, each one-half the width of the sector l, are hingedly connected at their outer edges to the outer edgesl of sector 'I and are adapted to be folded overto lie upon the'part 1, as shown in Fig. 1. The hingesindicated at 8a in Figs. 2 and 7 are of a concealed type which do not show from above when the parts 8 are folded outwardly through an arc oivlbf" to lie in the same plane with the part 1. When thus outwardly unfolded, one-half of the table top is provided.

Two horizontal bars `9 and l0 are hingedly connected at adjacent ends by a hinge I I, which has a vertical hinge pintle IIa extended downwardly (Figs. 4 and (5) below the hinge. The hinge I I is located at the rear of the center leg 3, which at its upper end is recessed as at I2, to provide space for entrance of the hinge when the parts of the table are drawn together, as will hereafter ap-A pear. A board I3 of the shape best shown in Fig. 3, is connected to the bar 9 and extends forwardly therefrom and has an outer curved edge with whlch'is connected a curved rail Ill. Similarly, a board I5 is secured to the bar IIJ and extends forwardly therefrom, has a curved edge and a o curved rail ifi connected therewith. The radius ofthe rail i6 is less than that of the rail Ill and the board I5 is located in a higher plane than the board I3, whereby the two bars El and Ill may be swung inwardly toward each other about the axis .of the hinge pintle` I Ia, so as to bring said bars 9 and I0 into substantial parallelism with the l frame bars 5', and as shown in Fig. 4, with the parts I5 and IB located over the part I3 and with the 5 curved rail I6 within the curved rail I4. Rollers ll mounted upon suitable brackets are connected to the front outer end portions of the rails I4 and. IS, (Fig. 8) and are adapted 'to bear against the under side of the top sector l.r When swung out- 55 wardly, so as to bring the bars 9 and l0 in horizontal alinement, as in Figs. 2 and 3, the bracketsv lia and passes forwardly through a horizontal.

opening in the leg 3. Its front end has pivotal connection to a rod 2i! which extends in a forward direction underneath the bar d, and at its front end is connected to'- aI hand lever 2i pivotally mounted at one end on a bracket 22 secured to the under side of the` bar i5 (Fig. 3). The connection or" the rod 2d to the hand lever 2l is at a short distance from the pivot of the hand lever. Swinging the hand lever in a clockwise direction thereupon causes the rod 2li and bar igto be moved longitudinally and thus moves the hinge lV l', the connected bar l t and the members i3, iii, i5 and i6 secured thereto forwardly. In this movement it willv be noted that the brackets carrying the rollers l?, engaging against the inner sides of the stops f8, may be moved directly forward, the sides of the stops i3 being' parallel to each other and parallel to the forward direction of movement imparted tothe bar hinge H and associated' and connected parts.

A top sector or quadrant 23 is hingedly connected by hinges 24 to andat the rear of the bar l?.A Similarly, a like top sector 25 is hingedly connected by hinges 2li to the rear portion of the bar lil. The two quadrants 23 and at their meeting edges are hingedly connected by hinges shown at Elia in Fig. 5. When the bars S andY lli have been moved outwardly into horizontal alinement with each other, as in Fig. 2, the two

topsectors

23 and 25 are in the same plane and may then both'together be lowered to a horizontal position, as in Fig. 2.

Each of the

top sectors

23 and 25 is designed to. be supportedby a vertical leg 2S pivotally mounted at its upper end on a bracket 2l, secured to the under side and toward the outer curved edge of its associated top sector. The legs are releasably retained in vertical position or in folded The movement position by spring members 2B.

' of the two

top sectors

23 and 25 to horizontal position is with the hand lever 2 lreleased, whereby ample space is provided so that the parts 8 may afterward be turned outwardly. Then the table top is closed by swinging the hand lever 2| in a clockwise direction, drawing the parts snugly together. It will be observed that the rod 20 will pass from one side to the other ofY the center ofthe pivot about which the hand lever 2l turns, and thus there is provided a secure lock against separation of the parts of the table top.

Cooperating interengaging spring catches 29 and 3Q on the bars 9 and lll and', shown in Fig. 3', are provided so that when the bars 9 and l@ are swung forwardly the catches 2S thereon will engage with the cooperating catch members 30 on the bars 5, to hold the bars 9 and l2 against accidental rearward movement.

When the construction is in its retracted and folded form as in Fig. l, the top sections 8' are folded over and lie upon the underneath section 1', the

top sectors

23 and 25 are in vertical position and have been turned, through their hinge 'connections at 2da, to lieY at right angles to each other. The bars 9 and iii' have been swung forwardly so that the interengaging catches 29 and 313 are in operative engagement. The legs 26 are folded against the rearsides of the

top members

23 and 25, as in Fig. 5. ln such position the structure is adapted to be placed in a corner of a room where it will occupy small space and the horizontal top provided by the two members 2,

may be readily used as a desk top or thelike.

When the structure is toI be converted into a J A, l

table, the rst operation after the` structure has been brought out into the middle part of the A room, is to swing the ytwo top sectors 23 and 2h This will disinto alinement with each other. engage the catchesy 29 and 3Q and move the bar-s 9. and l. into alineinent with each other. Such movement is stepped when the brackets carryin'g the. rollers il come against the stops i8. The

two hinged together

sectors

23 and 25 are thenV turned downwardly to horizontal position, ther supporting legs 26 having first been turned so as to take a verticalA position to support the sectors.

when they reach horizontal position. The'parts 8' are then turned outwardly. 'been done; between the adjacent edges of the parts 8 and the forward edges of the sectors'Y When this has` and' 25' there will' be a gap or space which is closed v by grasping the handle 2l and moving it counterclockwise to the position in Fig. 3. Said gap is closed' and the parts drawn together with cooperating pins or pegs shown best in Figs. 2' entering turn to the position shown in Fig. l is by reversal of these movements, iirst releasing the lock by turning the handle member 2l counterclockwise,

.30. the corresponding sockets or recesses to receiveI them in the adjacent parts of the top. The re# then swinging the parts. 3T over onto the under-I l neath top section l, after which the two sectors 2E' and' Z5 are turned to` verticalposition, and

then swung to the position shown in Fig.fl at I right angles to each other, with an automatic interengagement of the catches 29 and 33 astliey Of course the sup-.

reach their 'nal positions. porting legs 26' are folded, as in Fig. 5, against the adjacent sides of their associated top mem-`

bers

23 and 25.

The construction described is very zr'ractical and useful', is readily manufactured. and assembled and is very easily converted to occupy' the small space shown i'n Fig. 1,01'. the larger.

space where it 'is a table with a. horizontal top, as in Fig. 2. While the disclosure shows a table of circular outline with. the several parts i, 8,23 and 25 as sectors of a circl'e it is to be understood Athat sai'd parts l', 8, 23 and 25 are notnecessaril'y v restricted to outer curved edges inA the arc of a circle, but may be of a different shape and. outline than shown. For example, the sections of the table topI may be designed. so that. the coni-A pleted table top will be 'rectangular or square in outline. scalloped' or other and different departing from the invention.
