I (Cl. 211-90) 8 Claims.

. IV This invention relates to shelves and more particularly to an improved shelf for relatively small articles, which shelf is adapted to be installed or attached to a wall or a swinging door of a closure such as a kitchen cupboard or a bathroom medicine cabinet.

One of the objects of the present invention is to provide'an improved shelf for a closure, such as a kitchen cupboard, in which shelf disadvantages of prior constructions are overcome and largely eliminated.

Another object of the invention is to provide an improved shelf adapted to be attached to the door of a cupboard at the inner surface or side thereof and to clear the shelves inside the cupboard by a sufficient distance, when closed, and

when so installed to provide a convenient support for small items, such as spice cans and boxes, which often become covered by larger articles, and while occupying space, are often very difiicult to find unless some of such larger articles are first taken out of the cupboard.

concealed by the shelf, but such articles and their labels remain in full view of the observer.

A still further object of the invention is to provide an improved shelf of the character specified in the precedingparagraph and satisfying fully the object stated therein without the use of glass shelving common in medicine cabadditional cost -or the necessity of painting,

lacquering and the like.

A still further object of the invention is to provide an improved shelf of the foregoing character which is of such a construction that corners and other similar places accumulating crumbs, dust, and dirt are entirely eliminated; and, the

shelf may be easily taken off, disassembled in a very simple manner, wiped clean, reassembled and remounted in a similarly simple manner.

A still further object of the invention is to provide an improved shelf of the character specified in the preceding paragraph, which is very light and yet is of sturdy construction and possesses requisite rigidity and strength, both when operatively mounted and as a self-sustaining structure.

A still further object of the invention is to provide a shelf of the foregoing character, on

, which shelf individualized ornamentations, such inets; it is appreciated that the use of glass 2 would make a shelf of this general character prohibitively thick, heavy, undesirably large, present the danger of breakage, and would require molding of special glass section, which isan cost.

A still further object of the present invention is to provide an improved shelf for small articles, which can be easily attached to a wall or the A still further object of the invention is to provide an improved shelfof the character specified in the preceding paragraph, which shelf consists 'onlyof a few parts "and can becomexpedient of very high and often prohibitive as monograms and trademarks embossed in gold or color may be easily and inexpensively provided,

which operation is difficult and more costly, if metal or glass are used as the material for the i ornament receiving portions of the shelf.

A still further object of the present invention is to provide an improved shelf of the foregoing character which is exceedingly simple in con-- struction, safe and dependable in use, is inexpensive to manufacture, and may be made in any number of lengths without any special tooling up .or having a larger number of special models. 45"

Other objects of this invention will appear in the following description and appended claims,

reference being had to the accompanying drawings forming a part of this specification, wherein like reference characters designate corresponding parts in the several views.

Fig. l is a perspective view showing a shelf embodying the present invention operatively mount- -'ed on the door of a cupboard.

Fig. 3 is a front view of the shelf shown in Fig,

it is to be understood that the phraseology or ter minology employed herein is for the-purpose of:

description and not of limitation.

Referring to the drawing, there is shown by way of example a shelf embodying the present.

invention. The shelf illustrated in the drawing is shown attached .to the door of a cupboard and it has the dimensions and proportions making it particularly adapted for such an application. It will be understood however that the same shelf may be attached to a wall of a living room to hold ornamental articles such as small statuettes and the like, or be secured to a drawing board or a wall to hold ink, paint bottles or similar articles. It Will also be understood that the shelf may be made of different sizes and proportions and adapted to support such articlesasflower pots and the like.

The shelf illustrated in the'drawings comprises generally an angular member lii'and brackets II,

II mountable on the member llland adapted to be attached to a .wall, a doorof a cupboard or a similar shelf-supportingstructure. The member ID is preferably made of a uniform angular or L-shaped cross section from a transparent and relatively flexible plastic material, such as acrylic resin, cellulose acetate, various polyvinyl chlorideacetate compounds, and the like. Such materials possess sufiicient strength, are relatively flexible, i. e. possess flexibility permitting their bending and twisting, without cracking, in the degree very likely to be encountered in their intended uses; they are not readily inflammable, and are relatively inexpensive. Acrylic resins, in particular,

are stable dimensionally, do not warp, and are available in a great variety of exceedingly pleasing colors. Transparency of the'material is important in order that labelsor' other designations or indications of. the contents of small cans and bottles contained in the shelf do not become consisting of a horizontal leg or bar [la and a vertical leg or bar Ill). The terms such as horizontal, vertica upper, lower and the like are used herein for the purposes of description only, to designate portions of the construction herein disclosed which occupy, are disposed or extend, in the position of the construction shown in the drawing, in a manner described by such terms. The angular portion of each bracket is adapted to underlie and to support the angular shelf member NJ as shown in the drawing. At the upper end of the bar llb there is provided a suspension or supporting bar Ilc bent rearwardly to bring its extremity substantially into the vertical plane passing through the end Ila of the angular portion. The extremities of the supporting bar of each bracket is adapted to be connected to the wall or other shelf-supporting structure in any suitable manner, such as by the provision of holes I2 for the passageof screws or of hooks such as shown at l3. Use of hooks permits taking the shelf off without the use'of' screw drivers or similar tools. It is preferable to impart to the portion Hc downwardly directed curvature in order to form a side barrier for the articles contained in the shelf, which barrier does not extend upwardly for such a distance as to interfere with grasping the top of an article standing against the bracket.

Means are provided to retain the brackets H, H yieldingly in a desired position on the shelf member II). In the present embodiment of the invention said means are integral with the brackets II, II and are exemplified by curled portions provided on the ends of the horizontal bars Ila of the angular portions of the brackets. It is preferable to have such curled portion to include a, straight portion l5 extending for a sufficient distance to provide a flat portion bearing against the wall and merging into a curved, preferably spiral, or similar portion l6 bent to contact the shelf member ID at one' or more places. In the embodiment shown, the curled portion contacts the member ID at two places I! and I8. The brackets H are made of a material possessing some resiliency, and are of integral construction. It is preferable to make them from metal,

such as polished spring steel, brass, copper and the like, although brackets molded of plasticmaterials may also be used with success.

The curvature imparted to the coil or spiral i6 is preferably such that before the brackets cealed requiring takingseveral cans or bottles out 7 before the one desired is thus'found. It is also preferable to make the'memb'er' ll! ofintegral construction, rather than from two separate angularly disposed members, thereby preventing separation of the parts, decrease in rigidity and similar disadvantages. I prefer to make the member it by'bending a flat sheet of material, heating the sheet either bodily or only along the line of bending. However, the use of molded or extruded angular sections may also be of -advantage, particularly if the same are already "avail able as standard sections for cutting into any desired lengths. The term L-shaped cross section is used herein to designate bothany angular cross section, or a cross section resembling the letter L, i. e. having a low vertical bar at the end of the Each of saidbrackets ll comprises an angular portion con- II are put on theshelf member llLthere is some clearance at places where the spiral i6 is to contact the member l0 but such clearance, is

somewhat less than the thickness orthe member [0. By such an expedient, assembling the shelf member ID and brackets II is made easier, and when the shelf is assembled, the spiral I6 exerts on the 'shelf member a certain yielding pressure sufficient to retain the brackets and the shelf member-in their relative positions.

The manner in which each bracket may be assembled to the shelf member ID is illustrated in Fig. 5. After taking hold of the bracket, as shown, or in any other suitable manner, the bracket is spread and simply slipped. on. the member I0, from either-end thereof, into its intended position. Scratching of the member Hlis thus prevented. r 1 I It will now be clear in view of the lforegoing that by virtue of the'construction disclosed above my improved shelf possesses a number of important advantages both inits manufacture and inits use. -Its construction is reduced to extreme simplicity. In its operative position it has, in effect, all the advantages of an open box and has article retaining walls from all sides except the top. Yet all items contained therein are in full view from the very bottom t the top, and can be easily distinguished, removed for use and returned to their respective places. The shelf is strong and rigid both in its operative position and when taken off, with no parts falling out. It is adapted to be individualized by embossing in gold or in any color of various monograms and similar ornamentations, as illustrated in Figs. 3 and 4. Embossed with a trade-mark of a product, my shelf forms an excellent premium or advertising gift item. v

The proportions of the angle bars of the member I0 and brackets may be varied as desired, to provide a wide shelf with a low front wall, or vice versa, or to incorporate any desired relationship between the length and the width. More than one of my shelves may be used in one cupboard or on a wall, thus providing more useful or adequate facilities or particularly attractive ensembles. The plastic materials such as disclosed are easily broken along a scratched line, and therefore, should a user wish to reduce the length of the shelf member, all that is necessary is to move the bracket to the place desired, scratch the member with a sharp or pointed tool along the edge of the bracket and break off the portion of the member I 0, thus bringing such member to the desired length. By shifting brackets on the member In, the shelf may be adapted for a great variety of suspension conditions and be connected to the wall at practically any desired location.

For some applications it may be desirable to effect a very tight attachment of the shelf to the wall or other supporting structure. For such a requirement the use of screws instead of hooks such as I3 is desirable. With such or similar means of attachment, the head of the screw draws the upper end of the bracket very tightly against the wall, consuming the clearance resulting from the fact that the shape of the portion He is such that in the free suspension of the shelf such as on hooks, it is only the very tip or end of the portion He that touches the wall, as is shown at M in Fig. 4. Therefore, tightening of the screws or similar connectors, draws the 0 upper ends of the portions H0 at holes against the wall, which in turn causes the portions I5 of the brackets to bear with certain pressure against the wall, thereby ensuring tight and yet resilient attachment of the shelf.

My improved shelf may be used in a great variety of applications, as a spice shelf in a cupboard, as a shelf for a bathroom medicine cabinet; a shelf used on the side of a drawing table or on the adjacent wall as an ink or paint bottle holder, and in many other useful applications.

By virtue of the construction described above the objects of the invention listed above and numerous additional advantages are attained.
