- Application November s, 1938, Serial NQJIZ39A8Q' Y 11 Claims. (cram-90) This invention relates to shelves and particularly to a shelf which is made hollow and in two parts, each part being formed of sheet metal, these parts being adapted to be' joined together either in alinement or at right angles to each other. 1

' The invention consists in a shelf centrally divided into two parts, each part being closed at one end and opened at the opposite end, the opened ends extending transversely of the shelf parts at an angle of 45 degrees. a

The invention further consists in providing one part of the shelf with a" tubular extension preferably formed integral therewith, this extension projecting, from its open end and being adapted for insertion into the open end of the other part. The invention further consists in providing each shelf part with a wall bracket which may be connected quickly to either shelf part in difierent positions, said bracket having upwardly extending ears for insertion into elongated openings in eitherv the upper or lower walls of the twoparts of the shelf. I I The invention further consists in providing the vertical portion of each wall bracket with a keyhole slot by which the bracket may be locked in position upon a headed pin extending from a Vertical wall of a building. I

' The object of the'invention is to provide a demountab-le shelf in two parts which may be assembled to accommodate it to various conditions when securing it to a wall, as for instance against a fiat wall, into a recess of a walLoor around a iprojecting' corner of a wall;

This object is attained by the mechanism illustrated in the accompanying drawing. For the purpose of illustrating the invention, one preferred form thereof is illustrated in the drawing, this form. having been found to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention consistscan be variously arranged and organized, and the invention is not limited to the precise arrangement and organiza- Figure 2 represents a verticalsection thereof 1m 1m 2, 2 on Fig. 1;

Figure 3 represents a vertical section thereof on line3, 3 on Fig. 1.

"'Figur'e 4rep'resents a vertical section of the ,shelf and one of its supporting brackets, the

cuttingplane being on line 4, 4 on Fig. 1.

Figure'5 represents a plan of said shelf with its two partsjassembled at right angles to each other, I

Figu'reb represents a side elevation of said shelf.

- Similar characters indicate likeparts throughout the several figures .of the drawing.

In the drawinglis shown a shelf formed in two parts Ill and 'll",' eac'h.part being made up of sheet metal closedat' oneend l2 and opened at the other end l3. I

.The ends l3 of the two parts 10, Hare at an angle of 45' degreesto the side walls of the shelf. Th two parts III, II are hollow with an upper wall l4 and a lower wall Hi.

The part Ill has extending from its open end a tubular extension iii, the upper and lower walls I1, 18 of which are integral with the upper and lower walls 14, I5 and are slightly depressed therefrom, as shownat [6st, soas to fit within the open end of the part H and contact with the inner faces of] the upper and lower walls Mr, l5'x thereof.

The upper and lower walls ll, l8 of the extension IG each have parallel slots 19 formed therein perpendicular to the open end l3 of the partlll. I

In the part II the upper and lower walls Mr, l 5.1:jhave' struck therefrom ears 20. extending inwardly into alinernent with the slots I9 in the upper and lower walls I! and [8 of the tubular extension I6. I I Whentheftwo parts I0, II as shown in Fig. 1 are moved toward each other to lock the two parts together to form a straight shelf, the cars 20 will enter the slots l9 and prevent any lateral movement of one part III or II relatively to the other. v

, :Whenzthetwoparts Iii; I l. have been locked together in the "manner just described, the shelf is very' rigid owing'to the tubular character of the extension l6. 1 1 I a I Near the outer ends of the parts l0, 1 l l, the upper and lower "walls M, l5 have extending transversely therethrough near, the side edges thereof elongated slots 2|, and these slots are adapted to receive the upwardly extending ears 22 formed upon'the supporting brackets 23.

" These brackets 23 are made of spring metal and the body portion 24 of which is wider than the narrow ears 22.

Owing to this construction shoulders 25 are formed on the opposite sides of the ears 22 on which shoulders the shelf is adapted to rest.

The rear vertical portion 23:1: of the bracket 23 has a forward bend 26 therein on which the rear end of the shelf is adapted to rest when the ear 22 is inserted into one of the rear slots 2 I.

This rear vertical portion 23a: of each bracket has a keyhole slot 21 formed therein to coact with a headed pin 28 inserted into a vertical wall 29.

When it is desired to remove the bracket "23 from the shelf the forward curved portion of the bracket 23 may be sprung rearwardly until the It is believed that the many advantages of a shelf thus constructed will be fully apparent without further description.

Having thus described my invention, I claim:

1. A sectional shelf centrally divided at an angle of 45 degrees into two parts both formed rectangular in cross section of sheet metal, one part having integral therewith at its angular end an extension provided with a plurality of parallel slots, and the other part being open and provided with inwardly projecting ears integral therewith adapted for insertion into certain of said slots when the two parts of the shelf :are telescoped together.

forward ear 22 is removed from theslotZl in the forward portion of the shelf. 1

This having been done it is easy to disengage the shelf from the rear ear 22.

When the shelf is mounted upon the bracket .23 the spring tension of the metal will retain it in position and prevent accidental displacement thereof, the front ear being inclined outwardly. 7

When it is desired to mount the shelf on a corner walLthe part II may be inverted and then when inverted connected to the part Hi.

When this is accomplished the two parts l0,

. II will be in the position shown in Fig. 5 of the verted and then the brackets 23 secured to the lower walls thereof with the ears 22 extending into the elongated openings 2|.

The side walls of the shelf are'formed by flanges 30, 3| formed on the upper and lower walls [4, 15, these flanges overlapping and being secured together by spotwelding, as shown in l igs. 2, 3, andd. The upper and lower walls l1, I8 of the tubular extension I6 have flanges 32, 33 overlapping and spotwelded together asshown in Fig.2 of

the drawing, thus giving great rigidity to the extension l6;

It is obvious that the outer walls of the two parts H], II should have the same finish so that the walls of the two parts will conform to eachother regardless of which part II] or H' is inverted relatively to the other.

This makes a very convenient form of shelf, the brackets 23 thereof being removable quickly from the parts [0, II and capableof being secured to either the upper or lower wall of the parts 10, ll according to whether the two parts of the shelf are to be secured to a wall in alinement or whether these two parts II], II are to be disposed at right angles to each other to form a corner shelf in a recess or form a corner shelf surrounding a projecting corner wall.

A shelf thus constructed made up oftwo parts I0, H with removable brackets 23 therefor which may be secured to the shelf in various'positions is a great convenience as the various parts may be assembled to form shelves to suit various conditions.

The shelves may be cheaply constructed at little expense and being made of sheet metal they are very rigid and can support considerable weight.

2. A sectional shelf centrally divided at an "angle of45 degrees into two parts both formed sion provided with a plurality of parallel slots in whichthe walls of said slotted extension are depressed from the upper and lower walls of said shelf part; the other part being openat the angular end to receive said extension; and inwardly projecting ears integral with the upper and lower walls of the other part and adapted for insertion into certain of said slots when the two parts of the shelf are telescoped together.

3. A sectional shelf centrally divided at an angle of 45 degrees into two parts both formed rectangular of sheet metal, one part having integral therewith at its angular end an extension provided with a plurality of parallel slots in the upper and lower walls thereof, said slotted extension being tubular with its side walls secured together; the other part being open at the angular end to receive said extension; and inwardly projecting ears integral with theiother' part adapted for insertion into certain of said slots when the two parts of the shelf are telescoped together.

4. A hollow sectional shelf, made in two parts each part being rectangular in cross section and formed of sheet metal with wide parallel upper and lower walls and narrow front and rear walls, said parts having integral therewith means for positioning said parts in alinement or at right angles to each other when the two parts of the shelf are telescoped together. f

5. A shelf as set forth in claim 4 in which the upper and lower walls of each part between the front and rear walls thereof have a pair of equally spaced elongated slots therein parallel to the front and rear walls thereof, said slotspro'viding means whereby the upward extensions ofa bracket are insertable in the slots of either of said walls. I I

6. A shelf as set forth in claim 4 in which the upper and lower walls of each shelf part has two slots equidistant from and parallel with the front and rear walls thereof, a V-shaped supporting bracket of spring metal for each part, said brackets having at their upper ends narrow ears insertable into a selected pair of said slots in either the upper or lower wall of said parts, and'the rear portion'of each bracket having a horizontal portion on which the rear part of said shelf may rest.

'7. A hollow sectional shelf formed in two parts rectangular in cross section of sheet metal and having formed integral therewith means for positioning said parts in alinement or. perpendicular to each other and each part being provided with a pair of widely separated slots parallel to the front wall of said part and extending through each of the upper and lower walls, a Vrshaped bracket for each part, said bracket being formed of spring metal with narrow upwardly extend-e ing ears at the upper end insertable into a selected pair of said slots in either the upper or lower wall of each part of said shelf.

8. A shelf. as set forth in claim 7 in which the V-shaped supporting brackets are formed of flat spring metal and are removable freely from said parts, each of said brackets having at their upper ends narrow ears insertable into a selected pair of said slots in either the upper or lower wall of either part with its rear vertical portion alined with either the front or rear wall of said part.

9. A sectional shelf centrally divided at an angle of 45 degrees into two hollow parts each part being rectangular in cross section with wide parallel upper and lower walls and narrower side walls, one part having its upper and lower walls each provided with an offset member having two parallel open ended slots therein and extending outwardly from and perpendicular to the angular edge thereof and the other part being open and provided with inwardly extending integral projections extending into the slots of said members to properly position the two parts relatively to each other when the two parts of the shelf are telescoped together.

10. A shelf as set forth in claim 9 in which the two hollow parts thereof are formed with over: lapping flanges on the upper and lower walls forming closed front and rear Walls.

11. A shelf as set forth in claim 9 in which the two hollow parts thereof are formed of sheet metal with the ofiset members integral with and extending from one part narrower than the open end of the other part.
