SCHOOL DESK Ernest J. Kump, J r., San Francisco, Calif.

Application May 2, 1949, Serial No. 90,866

12 Claims. (Cl. 312-249) This invention relates generally to school furniture and more specificially to school desks.

At the present time the trend is to provide school furniture that is readily movable about the school room or from one room to another with each pupil having a desk and seat independently of the others and which desk is instantly movable to any desired location independently of the other desks and seats. Such a structure also facilities cleaning the school rooms. inasmuch as the desks can be moved about the room as desired.

I-ieretofore, most of the efforts directed toward providing structure of the above character, have been relatively crude, and the desks have been so designed that their assembly is a factory job instead of providing desks that have been so designed that they can be compactly packaged and then assembled at the final site or at least in the school shop, and without requiring skilled labor.

Also, most of the school desks heretofore designed are relatively heavy, therefore difficult to move around, and the means for securing them in assembled relationship is complicated and readily becomes loosened. Furthermore, at least some of the parts are usually of cast metal that is easily broken, and in others there are pedestals that interfere with the comfort of the pupils and that provide relatively insecure supports at the best, unless so massive as to be impractical and highly cumbersome.

Heretoiore, no desks of which I am aware prowide structure in which the desks may be nested one above the other, without disturbing the contents of the desks. In this connection, the term desks as just used refers to the desks for pupils and each of which has a receptacle for books and tablets and the like below which receptacle the legs of the pupil. extend when the pupil is seated. 'I do not refer to the storage cabinets or desks of the office type.

One of the objects of this invention is the provision of a very simple and economical made school desk that is adapted to be easily moved from place to place, and that is very stable and :solid, yet relatively light and easy to carry.

Another object of the invention is the provision of aschool desk that has several compartments for books and the like, one being a forward upwardly opening compartment for holding such books as are not in immediate use, and the other being a laterally opening compartment having a working top, and which desk is adapted to be supported on the floor by simple, strong means that is easily assembled and by unskilled labor 2 at the site where the desk is to be used or wherever desired, and which means is easily and economically made.

A still further object of the invention is the provision of school desks that can easily be nested one over the other without disturbing the contents, and which desk includes a laterally outwardly opening compartment having a bottom wall on which school books, and the like are supported, and which bottom wall is provided with means for preventing the articles supported thereon from sliding out of the compartment when the desk is shifted from place to place.

An additional object of the invention is the provision of a school desk having two pairs of generally U-shaped, tubular, metal members providing the four legs of the desk, and which members are connected adjacent their upper ends by means on which a receptacle for books and the like are adapted to be supported with such receptacle between said upper ends.

Another object of the invention is the provision of simple, easily adjustable means for varying the height of the desk, and a still further object is the provision of a simple desk structure that may easily and quickly be assembled and disassembled without requiring special or unusual tools.

Other objects and advantages will appear in the description and in the drawings.

In the drawings,

Fig. 1 is a vertical sectional view taken centrally through the desk.

Fig. 2 is a side elevational view of the upper portions of several desks in nested relationship. The lower ends of the legs are broken oil in this view.

Fig. 3 is a fragmentary front elevational view of the desk of Fig. l, centrally broken out to accommodate the view to the sheet. The lower ends of the legs are broken away.

Fig. 4 is an enlarged fragmentary sectional view more clearly showing one of the elements for releasably securing the top portion of the desk to the legs.

Fig. 5 is a sectional view, slightly reduced relative to the scale of Fig. 4, showing the preferred means for holding the leg extensions in place.

Fig. 6 is a vertical sectional view similar to that of Fig. 1 but with the legs broken away, showing a structure that is slightly modified from that of Fig. 1.

In detail, the invention herein illustrated comprises a receptacle for books and the like, generally designated l, which is divided by a vertically extending wall 2 into a first compartment 3 and a second compartment 4. There are two opposed side walls 5, 6 to compartment 3 that may be extended at 1, 8 to provide two corresponding side walls for compartment 4.

Compartment 3 has a bottom wall 9 and a top wall I6, with the top wall slightly slanted downwardly from the upper edge of the dividing wall 2 providing a working surface.

The rear side of compartmentt, which is the side that is adapted to be adjacent a pupil when the latter is seated at the desk, opens laterally and rearwardly, and the marginal portion of the bottom wall 9 along said open side is turned up slightly, as at H to prevent articles on bottom 9 from sliding out of said open side when the desk is shifted about, and the free edges of said marginal portion are rounded. Also the juncture between said marginal portion and the bottom wall is preferably curved.

The dividing wall 2 at the forward end of compartment 3 extends downwardly past the forward edge of bottom wall 9 a substantial distance, and at a slight forward incline from its top to its bottom edge. This downward extension is indicated at i3.

The compartment 4 has a bottom wall i l at the lower end of wall l3 and the side walls 7!, 8 extend to said bottom wall. A forward wall [5 is preferably parallel with the dividing wall 2 and spaced forwardly therefrom, it being understood that wall 2 has the same incline from top to bottom as the extension It.

The upper end of compartment i opens upwardly so that books or the like may be inserted generally Vertically therein, and a cover i7 is hingedly secured at E8 to the upper edge of the front wall [6 for closing the upper end of said compartment 4.

An upwardly opening horizontally extending recess is partially formed in the upper edge of wall 2 and in a horizontal strip 20 in compartment 5 along said upper edge for holding pencils, pens and the like, and a lip 2! along the rear edge of closure or cover I! is adapted to extend over said recess when the cover is closed, and when the pencils and pens are in said recess. The ends of said recess are adjacent side walls 5, 6 and are closed by the latter. Thus, when the desks are shifted about, the pencils etc. are securely held in them from accidentally falling out.

At any desired point in compartment 4 at its upper end there may be a block 22 apertured for holding an ink well 23 therein. The cover I? preferably lies close across the top of said ink well and covers the same when the cover is in closed position. In Fig. 1 the block 22 is in a right hand corner alongside the dividing wall 2 and alongside side wall 8.

The means for supporting the receptacle i comprises a pair of inverted generally U-shaped, tubular members each being generally designated 25. These members are spaced apart the distance between the oppositely outwardly facing surfaces of the lateral sides 5, 6 of compartment 3, and they are preferably identical in contour and size, each being formed from a length of square metal tubing, preferably such as aluminum or an aluminum alloy.

By the above structure, four legs are provided. there being a pair of front legs 26, these being one from each U-shaped member, and a pair of rear legs 21, which are the other legs of said members. The word rear refers to the legs nearest the side of the desk at wh ch. he p pi is to sit, and the word front refers to the legs that are nearest compartment 4 or that are most remote from the side at which the pupil would be seated.

Preferably the legs 26, 21 extend divergently downwardly, and a curved inverted U-bend 28 connects them at their upper ends. The degree of inclination of legs 25 is the same as the inclination of the dividing wall 2.

A rear cross bar 30 connects legs 2'5 adjacent their upper ends, but spaced from the top of bend 28 and a similar front cross bar 3| connects the upper ends of legs 26 at the same level.

These cross bars are preferably of the same material as the legs 26, 2'! and of the same contour, but are slightly tilted about their longitudinal axes so that one of their corners is the uppermost part of each bar.

Bottom 9 is recessed at 32 in its under side to receive these corners, and the bars are so spaced below the uppermost sides of bends 28 that the said sides will be almost even with the top l8 when the bottom 9 is supported on said bars with the latter in recesses 32. The recesses will, of themselves, tend to hold the receptacle i from shifting horizontally in a plane parallel with those in which the members 25 are positioned.

The tubes from which the members 25 are formed each have one of their flat sides at their upper ends substantially against the outer surface of one of the side walls 5, E, thus the compartment will tend to be held against shifting transversely of the members 25, and at the same time the receptacle will function as a brace for the legs since the latter cannot sway transversely of the planes in which the members 25 are respectively positioned when the receptacle is between their upper ends.

Supported on cross bar 381 is a spring urged pin 35 that slidably extends through said cross bar. A spring 36 around said pin functions to yieldably urge the pin longitudinally thereof for re" leasably holding one end 36' thereof in a recess 31 formed in a block 38 that is secured to bottom 9 of receptacle 1. This pin extends generally horizontally, hence when it is in position with the end 36 in recess 3'! (Fig. 4) the receptacle cannot be lifted off the cross bar 3i The dividing wall 2 is formed with a horizontally extending recess or slot 39 in which cross bar 3| is adapted to extend the rear edges of the downward extensions I, 8 of the side walls being recessed to receive said cross bar adjacent the ends of the latter. This structure prevents the receptacle from being lifted from the cross bar 3| until the pin 35 is withdrawn from the recess 31.

The pin 35 has a head 48 on the same for grasping by the fingers to release the same from recess 31.

If desired, the U-bends 28 may be apertured transversely for screws 4|, but usually these are not essential, particularly where the receptacle snugly fits between said bends.

It is also desirable that the desk be adjustable to different heights, and in the present instance the means for accomplishing this result comprises the provision of extension legs 42 having an external cross sectional contour the same as the inside cross sectional contour of legs 25, 21. These extensions telescopically fit within the lower ends of legs 26, 21 and are transversely apertured at 44 for a pin 45 (Fig. 5) that may be threaded adjacent its head for threaded engagement with a threaded section of each opening 44-. These may be Phillips screws so as to prevent unauthorized tampering therewith by the pupils.

' The desired adjustment may be had by removing the screw in each leg and sliding the extension to the desired height; then replacing the screw in the new opening.

The lower end of each extension 42 is provided with a rubber foot 46 to prevent marring the floor as well as providing a friction surface, and cushion.

In the desk shown in Fig. 6, the receptacle, generally designated 50, has a rear compartment below top 52, and this compartment is practically the same as compartment 3, except that the top is shown as being level. Obviously, said top could be inclined the same as top It.

In the invention as shown in Fig. 6, the bottom 65 of compartment 5| is continued forwardly as at 53 to form the bottom of the forward compartment 54. Thus, the vertical depth of compartment 54 is not as great as that of compartment 5.

The cover of compartment 54, which is indicated at 55, is hinged at 56 to the front wall 5'5 of said compartment.

A dividing wall 58 is the partition between compartments 5| and 54.

Recesses 59 in the bottom wall 52 receive the cross bars [ill of the inverted U-shaped members. These members and cross bars are identical with those already described, except that both are provided with the spring urged pins El and a block 62 is recessed the same as block 38 of Fig. 1 to receive the pins.

'The tops ll (Fig. 1) and 55 (Fig. 6) may be formed with upwardly opening grooves 53 for holding pens or pencils.

The desks of both forms of the invention may be stacked in the manner shown in Fig. 2. The invention as shown in Fig. 6 permits greater ease in stacking. and more desks can be stacked. However, the capacity of the desk of Fig. 6 is less in that it will'not take as large books as the form shown in Fig. l and at the same time permit the top 55 to close. This is unimportant in those classes where smaller books are used.

The desks of either form are quite light in weight, yet are very rugged and are more durable than the conventional desks that employ many bolts or screws to hold them together.

With the present invention, no screws are required in most instances, and amaximum of only several are used in those instances where they may be desired. No great amount of skill is required in setting up the desks, hence they can be shipped directly to the site, disassembled and quickly assembled on said site by such labor as may be available.
