FOLDING DESK AND SEAT Filed Feb. 15, 1946 Leb fRo ca l.

V QMZW Patented Nov. 21, 1950 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to collapsible furniture and more particularly to a seat combined with a desk or table in a unitary manner, the entire structure being capable of :being quickly opened to an upright position for use as a desk or table and being adapted to be readily folded into a compact package for storing when not in use.

One of the objects of the present invention is to provide a novel unitary seat and desk construction which is so constituted that it may be quickly folded into a, compact unit which occupies very little space.

Another object of the invention comprehends a folding seat and desk construction which is so arranged as to be capable of being opened in a simple manner and without the necessity of resorting to the manipulation of auxiliary locking devices.

A further object includes the provision of a novel and unitary construction of the above character which embodies a plurality of parts which are pivotally connected together in such fashion that the arrangement may be quickly opened or folded by the application of a minimum of effort.

A still further object resides in providing a relatively simple construction of the above type which includes front and rear supports, a seat and a table or desk top, these parts being arranged so that when folded, one of the supports is received within the plane of the other While the top and seat are folded against opposite sides of the nested supports.

Still another object includes a novel arrangement of parts in a construction of the above type which is capable of being manufactured at a relatively low cost and which is highly efficient in operation.

Other objects and novel features of the invention will appear more fully hereinafter from a consideration of the following detailed description when taken in connection with the accompanying drawing wherein one embodiment of the invention is illustrated. It is to be expressly understood, however, that the drawing is utilized for purposes of illustration only and is not designed as a definition of the limits of the invention, reference being had for this latter purpose to the claims appended hereto.

Referring to the drawing, wherein similar reference characters refer to similar parts throughout the several views;

Fig. 1 is a perspective view of a folding seat and desk construction embodying the principles of the present invention Fig. 2 is a sectional view of the construction of Fig. 1 taken along line 22 of the latter;

Fig. 3 is a side view of the construction of Fig. l in folded position;

Fig. 4 is a perspective view of the plate attached to the under side of the desk top and illustrates the manner of adjusting the position of said to and Fig. 5 is a, perspective View of one of the angle brackets with which the forward portion of the seat cooperates.

Referring more particularly to Fig. l, a uni tary folding seat and desk construction embodying the principles of the present invention is illustrated therein in open position for use, and includes front and rear supports Ill and I2 respectively, a seat l4 and a table or desk top IS, the latter being capable of being adjusted to various angles, as will appear more fully hereinafter.

In order to provide an unusually compact construction when the apparatus is folded, the front support I!) comprises a pair of

spacedapart legs

18 and 20, to which

rear legs

22 and 24 are respectively pivoted as by means of suitable pivot pins or

bolts

26 and 28. It will be noted that the pivotal connections between the rear and front legs are spaced a slight distance below the upper ends of the front legs, this distance being preferable such as to permit the top 16 to be adjusted to a substantially vertical position so that the device may be used in the nature of a black board or easel, if desired. It will also be noted that the

rear legs

22 and 24 are pivoted to the inner sides of the forward legs l8 and 20, this construction permitting the rear legs to be arranged in the plane of the front legs when the device is folded, as illustrated in Fig. 3. This latter construction also allows the rear legs to be positioned relatively close together so as not to interfere with the legs of the user when seated on the seat l4 facing the top l6, while still maintaining the desired degree of stability. However, it will be appreciated that the invention is not limited to this construction, since the

rear legs

22 and 24 may be pivoted to the outer faces of the legs I8 and 20, if desired. As shown, the front legs l8 and 20 are secured together adjacent their lower ends by a support member 30, while a rod or other suitable member 32 secures the lower portions of the rear legs 22 and 24' together.

' A novel arrangement is employed by the present invention for associating the seat M with the parts heretofore described, in such a manner as to materially facilitate opening of the apparatus and to present an unusually compact structure when folded. In the form of the invention illustrated, such arrangement includes a pivot member or block 34 to which the seat 14 is secured, as by means of screws 35, the said block being provided with suitable bearing pins 38 which are rotatably mounted within openings provided in the

legs

22 and 24. In order to lock the seat in the open position shown in Fig. l and to guide the same during the folding operation, the front portion of the seat is provided with a pair of screws or headed pins 49, disposed on opposite sides of the seat and received and guided within generally vertically extending

slots

42, 44 of the respective brackets 45 and 48. These latter are mounted at their upper portions on the

respective pivot pins

26 and 28 and each bracket is provided with a laterally projecting flange 50 which is secured to the front face of each of the front legs i8 and 23 as by means of screws, not shown. Referring more particularly to Figs. 2 and the lower ends of the slots 42 and 4'4 in the respective brackets 45 and 48 are formed to provide latching parts which are directed forwardly and upwardly. As shown particularly i Fig. 5, the upper ends of the lower extremities of each slot are directed upwardly at 52 in order to form a locking lug or tongue 54. By such an arrangement, when the apparatus is assembled, as illustrated in Fig. 1, the screws 4e are locked in the portions 52 against accidental displacement and possible collapse of the apparatus when the latter is in use. It will be observed from Figs. 1 and 5 that the flanges 5t and the main body portions of the brackets and 4B are so constructed that when the rear legs are folded within the front legs, each of the rear legs is disposed between an adjacent front leg and the main body portion of the bracket secured to such adjacent front leg.

In order to adjustably mount the top I6 on the front support H], a novel bracket construction 56, secured to the under side of the top as by means of screws 58, is provided the same including a pair of downwardly extending ears 6i! and 62 which are respectively connected to the upper ends of the legs l8 and by pivot pins or

bolts

64 and 66. For the purpose of locking the top It in any desired position of adjustment, the ear B2 is enlarged, see Fig. 4, to provide an arcuate slot 68 for receiving a locking bolt 74. A wing nut 72 cooperates with the bolt 70 to secure the top in position after the desired angularity of the latter has been secured.

With the device set up as illustrated in Fig. 1, it will be apparent that the top may be readily adjusted to any position desired by the user seated upon the seat M. For example, the top may be arranged horizontally for use as a card or utility table, or may be tilted at any convenient angle. Since the top i6 is preferably constructed of wood, it may be used as a drawing board and the drawing paper afiixed thereto by the usual thumb tacks. In a position approaching the vertical, the top may be used as an easel or in the manner of a black board. It will be observed that the weight of the user maintains the screws 48 within the upper portions 52 of the slots and thus the entire construction is rigidly braced against folding or collapse.

In folding the device, the wing nut 12 should be first loosened in order to fold the top l6 against the forward legs, and thereafter tightened to ma n ain the top firml position. Thereaf er.

it is only necessary to grasp the upper portion of the top I6 in one hand and move the seat upwardly with the other hand to bring the screws 49 to the lower extremities of the

slots

42 and 44, and then press downwardly on the seat in order to pivot the latter about the pivot pins 38. During this latter movement, the screws 4!] will travel upwardly in the

slots

42 and 44, and the parts will finally assume the compact folded position shown in Fig. 3, where the rear support 24 is nested within the front support ID and the seat I4 is parallel to and folded against these parts.

When it is desired to open the device for use, the seat I4 and top H; are grasped as heretofore, and the seat lifted in order to pivot the latter about the pivot pins 38 and move the screws 40 to the lower ends of the

slots

42 and 44. Thereafter the device is tilted upwardly about the front legs I8 and 2!] whereupon the screws 45) will automatically move into the portions 52 of the slots and be locked therein. The top i6 may then be adjusted to the desired position and locked therein by the wing nut construction heretofore described.

There has thus been provided by the present invention a novel unitary foldable seat and desk construction which is susceptible of a wide variety of uses, and which may be readily set up and folded with a minimum of effort. When in folded condition, the device is exceedingly compact and only occupies about the same space as the conventional folding card table. The unit is especially adaptable for use by children, but it is to be understood that the same may be constructed in various sizes for a considerable number of purposes.

While one form of the invention has been shown and described herein with considerable particularity, it will be readily understood by those skilled in the art, that various changes and rearrangements of the constituent parts thereof may be resorted to without departing from the spirit of the invention. Reference will therefore be had to the appended claims for a definition of the limits of the invention.
