516, wl., H. L. SCHRGEDER 29%@9274 ADJUSTABLE SHELF Filed Jan. 19, 1939 Patented Dec. 16, 1941 UNITED STATES PATENT OFFICE 11 Claims.

My invention relates to adjustable shelves adapted for-use in closets and other closed places. It is also adapted to be used as a temporary shelf which maybe closed up and stored when not wanted.

One object is to provide an adjustable metal shelf which may be purchased in hardware or department stores, and which the purchaser may himself put in place.

A second object is to make part of the adjusting means serve as clothes hooks located under and supported by the shelf.

A third object is to provide metal brackets which may be conveniently attached to opposite walls of a closet and will serve to support the shelf.

Other objects will appearfrom the description to follow.

In the accompanying drawing Fig. 1 is a front elevation of the shelf supported on brackets secured to the walls;

Fig. 2 is aplan;

Fig. 3 is an enlarged partial section on lin 3-3 of Fig. 1;

Fig. 4 is a similar enlarged section on line 4 4 of Fig. 2; and

Fig. 5 is an enlarged perspective view of one of the clothes hanger units. A

A On the Walls I and II are secured metal brackets which are in the form of sheet metal channels I2, each having the outer part of the upper'ange bent downward and inward at an angle of about 45 degrees. At two or more places in the acute angle formed by each bend are holes thru which, and other holes in the webs of channels, may be driven nails I3 to secure the brackets to walls I0 and II.

The shelf consists of fiat metal plates I4 and I having their longitudinal parallel edges turned downwardly and inwardly as shown at the left in Fig. 3. As thus made, the plates I4 and I5 are telescopically adjustable with respect to each other.

In the lower plate are two parallel rows of holes I 6, which may be spaced conveniently at onequarter of an inch from veach other. In the upper plate are superimposed rows of holes I1 in which the spacing between holes is two or three times the spacing in the lower plate.

With the plates constructed as described, the smaller one is telescopiccally fitted into the larger one, and they are pushed together until the length over all is a few inches shorter than the distance between walls I0 and I I. Then the end of one of the plates is mounted upon the lower ange of the adjacent bracket I2, and the other plate is moved with -respect to the first -plate until it is similarly mounted on the other bracket.

With the plates in this position, any pin which in the lower plate will act to prevent the shelf from displacement, provided that the pin has a head which will prevent it from falling out.` A common nail will serve the purpose.

I prefer, however, to utilize the securing means to accomplish a second result. In doing this I? lprovide a bar I8 (Fig. 5), which has in it two screw threaded holes I9 which are spaced from each other some multiple of the spacing of the holes I1, and then use screws 20 to clamp the bar I8 against the lower face of the lower plate I5. On the ends of the bar I8 are hooks 2| which serve as clothes hooks.

As there are numerous holes adjacent to both front and rear sides of the shelf, I may use as many of these pairs of clothes hooks as may be desired. Also, they may be placed near the :front edge of the shelf, or near the rear wall of the shelf as may serve convenience.

When making one plate adjustable with respect to another, it is common practice to cut a flong slot in one or both of the plates, and: then clamp them together by a. screw which passes thru both plates. Unless the plates are of heavy stock, such slots materially weaken the plates. As it is desirable to have a shelf of this kind of light material, and also -capable of carrying heavy loads, I use a series of holes in each plate because such holes weaken a plate much less than does a long slot. As it is desirable to have small adjustments in the overall length of the shelf, I make closely spaced holes in the inner and protected element I5 of the telescopic arrangement, and wider spacing in the outer and protecting element. Then, instead of making each hook ZI as a nut for each screw 20, I connect two hooks together by a bar I8 which serves as av brace under those parts of the shelf which carry thefgreatest load.

Figs. l and 2 illustrate theclothes hooks 2l distributed irregularly., This is simply for the purpose of illustrating the fact that they may be put at any convenient places where holes I6 and I1 are available. Assume that four bars I3 should be placed in a rectangle at about the middle of the shelf I4--I5, and a distance apart equal to about one-fourth of one-third of the distance between walls I0 and II. The re1ation` ship of those hooks to each other would be that e shown at A in Fig. 1, but' with a. greater distance between. Assume a second adjustable shelf of a width shown in Fig. 2, but of one-fourth or onethird of its length, and with larger holes near the ends and in line with the holes I6 and I'I. 'Ihe location of these larger holes would be at about the point B of Fig. 4. This shorter adjustable shelf may be hung on the hooks 2|, `which have the relationship shown at A, but more widely separated..

Thus, a single pair of brackets on opposite walls may be made to support two shelves and many clothes hooks, some of which may be under the lower shelf. By making the hooks 2i which are used to support the second shelf longer than their companion hooks on the same bars i8, the lower shelf may be at any desired distance below the upper one. By turning the lower shelf up side down, and having its telescopic connection wide enough to come adjacent to the similar connection shown in Fig. 3, the lower shelf will have the outside appearance of being a box, but will really be a shelf open at its ends. Such a shelf will be a convenient cubby-hole for storing articles of more use than beauty.

What I claim is:

1. In a metallic shelf construction, a pair of extensible overlapping plates, each having longitudinally extending marginal anges contacting for the overlapped portions of the plates, supports for the outer ends of the plates and means for clampingly connecting the plates together at a plurality of longitudinally spaced points to restrain the plates from relative sliding movements when under load.
