June 9, 1964 ADJUSTABLE SHELVING Filed Oct. 24, 1962 E. J. VON ARB ETAL 2 Sheets-Sheet l INVENTORS- EDWARD J. VON ARB LOWELL W. DUNBAR BY JACK M. CLEMENT Moan United States Patent F This invention relates to adjustable shelving apparatus in general and, in particular, to adjustable shelving apparatus having shelves which may be disposed in any one of three positions.

The rapidly increasing need for store fixtures in the ever expanding commercial system of the United States,

particularly with reference to drug and grocery stores which are expanding not only in size but in the variety and quantities of products carried in open display, has brought a demand for shelving that is easily disassembled, reassembled, and adjustable as to inclination for displaying the goods. It is particularly important that these shelves when reassembled be as sturdy and solid as shelves of the older types which were connected at all joints with nuts and bolts in order to carry the weight of the items displayed thereon and to be able to stand steadily by themselves when they are utilized away from the support of a side wall. Many types of shelving have been advanced to solve this problem with each of the shelvings thus far advanced still having difficulties in overcoming one or more of the problems of instability, easy and quick disassembly, quick reassembly, etc.

It is, accordingly, an object of this invention to provide an improved adjustable shelving apparatus.

It is a further object of this invention to provide improved adjustable shelving apparatus which may be quickly assembled and disassembled, is stable, and has means for adjusting each of the shelves to any one of three positions with no more effort than the assembly of the shelves.

In accordance with the above objects, the invention features adjustable shelving apparatus comprising a pair of upright standards. Each of the standards includes a first upwardly extending plate, a second upwardly extending plate, and means for joining said upwardly extending plates to form an upwardly extending corner post. The first plates of the standards extend toward each other in preferably substantially the same plane. A shelf extends between the second plates. At least one of the second plates has a vertical row of brackets extending inwardly toward the shelf, each bracket having an inwardly facing surface and an upwardly facing surface. The first plate associated with the one second plate having the vertical row of brackets has formed therein a vertical row of pairs of vertically displaced slots, there being one pair of slots associated with each bracket formed in the second plate. A downwardly extending flange adapted to support and secure the end of the shelf is attached to of integral with the shelf. A projection extends from the rear of the shelf. The flange has a first downwardly opening recess with a downwardly facing and an outwardly facing surface, the outwardly facing surface being inclined downwardly and inwardly'toward the first plate. The projection is received by an upper one of a pair of slots to bear against upper and lower limits of the slot while the surfaces of the recess and the surfaces of the associated bracket cooperate to maintain the shelf in a substantially horizontal position. The projection also is receivable by a lower one of the pair of slots to bear against upper and lower limits of the slot while the surfaces of the recess and the surfaces of the associated bracket cooperate to maintain a' shelf in an upwardly slanting position.

Patented June 9, 1964 In this embodiment any one of a number of other means may be utilized for supporting the other end of the shelf on the other standard. The flange also has formed therein a second downwardly opening recess spaced forward from the first recess and also having a downwardly facing surface and an outwardly facing surface. A second projection extends from the rear of the shelf and is displaced vertically below the first mentioned projection. The second projection is receivable by a lower one of a next pair of slots above the first-mentioned pair of slots to bear against upper and lower limits of the slot while surfaces of the second recess and surfaces of the bracket associated with the first-mentioned pair of slots cooperate to maintain the shelf in a downwardly inclined position. It is preferable in this modification that each recess be spaced from the rear of the'shelf and the projections thereon to provide a wedging action by the engagement of the outwardly facing surface of the recesses against the bracket to insure the projection hearing against the upper and lower limits of the slot in which it is inserted.

The inventionherein further discloses a pair of upright standards wherein each of the standards includes first and second plates joined at substantially right angles. The first plates of each standard extend toward each other. A shelf extends between the second plates. Each of the second plates has a vertical row of uniformly spaced pocket means attached thereto or integral therewith and extending inwardly toward the shelf. Each of the first plates has formed therein a vertical row of pairs of vertically displaced slots, there being a pair of slots formed in each first plate for each pocket means of the respective second plate jo'med thereto.

Each shelf end has a downwardly extending tongue adapted to be inserted in the pocket means. A projection is formed on the rear of the shelf at each end thereof, each projection being receivable by an upper one of a .pair of slots to bear against upper and lower limits of said slot while each of said tongues is inserted into an associated pocket means to maintain the shelf in a horizontal position. Each of the said projections is also receivable by a lower one of said pair of slots to bear against upper and lower limits of the slot while each of the tongues is still inserted into the associated pocket means to maintain the shelf in an upwardly inclined position.

A second projection is provided on the rear of each end of the shelf displaced vertically below each of the first-mentioned projections. Each end of the shelf has a second downwardly extending tongue spaced forward from the first mentioned tongue. Each of the second projections is receivable by a lower one of a next pair of slots above the first-mentioned pair of slots to bear against upper and lower limits of the slots while the second tongue is inserted into the first-mentioned associated pocket means to maintain the shelf in a downwardly inclined position. It is preferable that each of the tongues has an outwardly facing surface which is inclined downwardly and back toward the first plates whereby the outwardly facing surfaces engage the front of the pocket means in each of the above defined positions of the shelf to provide a wedging action to seat the projections in the slot in question for each position of the shelf and insure the stability, rigidity, and strength of the easily assembled shelves.

Other objects, advantages and features of this invention will become apparent when the following description is taken into conjunction with the accompanying drawings, in which:

.FIG. 1 is a-view in perspective taken from below to more clearly show the features of the invention;

FIG. 2 is an enlarged plan view of the pocket or bracket means with a cross section taken at the top of the pocket;

FIG. 3 is a cross sectional view of FIG. 1 taken along the lines 33 of FIG. 1 that shows the operation of the features of this invention with the shelf in horizontal position;

FIG. 4 shows the upwardly inclined position of the shelf; and 7 FIG. shows the downwardly inclined position of the shelf.

Referring now to the drawings the invention will be discussed with respect to the preferred embodiment.

There is shown a pair of upright standards 20. Each of the standards includes a first upwardly extending plate 21, a second upwardly extending plate 22 and means for joining the upwardly extending plates to form an upwardly extending corner post (shown as integral in the drawing, but any other suitable means will be satisfactory). The first plates 21 of the standards 20 extend toward each other and are preferably in substantially the same plane. A shelf 30 extends between the second plates 22. At least one of the second plates 22 has a vertical row of brackets 40 extending inwardly toward the shelf 30, each bracket 40 having an inwardly facing surface 41 and an upwardly facing surface42. The first plate 21 associated with the second plate 22, having the brackets 40 formed therein, also has formed therein a vertical row of pairs 50 of vertically displaced slots 51, 52, there being one pair of slots 50 associated with each bracket 49 on the second plate.

The shelf 30 has a downwardly extending flange 31 which is adapted to support and secure the end of the shelf 30 adjacent the second plate 22. The flange 31 may be formed integral with the shelf 30 as shown in FIGS. 3, 4 and 5, or may be a separate angle iron which is suitably attached to the shelf as shown in FIG. 1. All longitudinal and depth bracing that normally are associated with the bottom of the shelf 30 have been omitted from the drawings in order to simplify and clarify the presentation of the invention. The rear of the shelf has a first projection 95 extending therefrom. The flange 31 has a first downwardly opening recess 80 with an outwardly facing surface 82 and a downwardly facing surface 81. The outwardly facing surface 82 is inclined downwardly and inwardly toward the first plate 21. The projection 95 is receivable by the upper one 51 of the pair 50 of slots to bear against both the upper and lower limits of the slot 51 (as best seen in FIG. 3) while the surfaces of the recess 81 and 82 and the surfaces 41, 42 of the associated bracket cooperate to maintain the shelf 30 in a substantially horizontal position. The projection 95 is also receivable by the lower one 52 of the pair 50 of slots to again bear against upper and lower limits of the slot 52 while the surfaces 81, 82 of the recess and the surfaces 41, 42 of the associated bracket cooperate to maintain the shelf 30 in an upwardly slanting position (best seen in FIG. 4).

Flange 31 has formed therein a second downwardly opening recess 90 spaced forwardly from the first recess 80 and also having a downwardly facing surface 91 and an outwardly facing surface 92. A second projection 96 extends from the rear of the shelf and is displaced vertically below the projection 95. The second projection 96 is receivable by a lower one 52 of a next pair of slots above the first mentioned pair (best seen in FIG. 5) to again bear against upper and lower limits of the slot while the surfaces 91, 92 of the second recess 90 and the surfaces 41, 42 of the bracket 40 associated with the previously utilized pair of slots cooperate to maintain the shelf 30 in a downwardly inclined position.

It is to be noted that each recess is spaced from the rear of the shelf and the projections thereon to provide a wedging action by the engagement of their inclined surfaces against the rearwardly facing surface of the bracket means. This insures that the projection will fully be inserted in the appropriate slot and bear against the upper and lower limits of the slot.

It is to be noted that the invention has been described with reference to utilizing the adjusting means at only one end of a shelf apparatus. While it is most preferable to use the same adjusting apparatus for both ends of the shelf it is possible to utilize other means of positioning the far end of the shelf since the connections made in the adjustable apparatus shown are so rigid and stable that the shelf may be properly held in position without repeating the apparatus at the other end. For example, a simple dowel extension from either the shelf flange or the plate 22 into an aperture formed in the other would be sufiicient to support the shelf to hold merchandise properly displayed. It is to be further noted that when the adjustable arrangement is utilized only on one end, then means should be provided to maintain the pair of standards in an upright position and properly space one from another. For example, back support or base support means could be added in the manner well known to those skilled in the art as shown in United States Patent No. 3,044,631. However, if the adjustable apparatus as shown and described herein is utilized for both ends of the shelf and for both standards, a shelving unit is obtained which is sufficiently rigid, stable, and strong to stand by itself without the use of a back or an enlarged base. Obviously, a base or a back may be utilized for decorative purposes even in such instances. However, they are not necessary for the purposes of strength and stability.

To be more specific in the description, the first plate 21 and the second plate 22 is shown joined at a substantially right angle. Each of the second plates 22 has a vertical row of uniformly spaced pocket means 40 attached thereto or formed integral therewith and extending inwardly toward the shelf 30. Each end of the shelf 30 has a downwardly extending tongue 60 adapted to be inserted in a pocket means 40. The projection 95 is receivable by an upper one 51 of a pair of slots 50 to bear against the upper and lower limits of the slot while each of the tongues 60 are inserted into associated pocket means 40 to maintain the shelf in a horizontal position (best shown in FIG. 3). Each of the projections 95 at the end of the shelf is also receivable by a lower one of 52 of said pair of slots to bear against upper and lower limits of said slot 52 while the tongue 60 is inserted into the associated pocket means 40 to maintain the shelf in an upwardly inclined position (best shown in FIG. 4).

Each end of the shelf 30 has a second downwardly extending tongue spaced forward from the first tongue 60. This tongue is utilized when second projections 96 at each end of the shelf are inserted into the lower one of the next pair of slots above the pair utilized for the previous two positions. Then the second tongue 70 is inserted into the same pocket means 40 to maintain the shelf 30 in a downwardly inclined position. It is to be noted that each of the tongues 60 and 70 has an outwardly facing surface 82, 92 which is inclined downwardly and back toward the first plates 21 whereby the outwardly facing surfaces 82, 92 engage the front 41 of the pocket means 40 in each of the above-defined positions of the shelf 30 to provide the wedging action to insure that the projections are seated in the slot in question for each of the positions of the shelf.

There has thus been disclosed and described a preferred embodiment of the invention which enables the use of a positive locking action in each of the positions of the adjustable shelf thereby insuring a stable, steady load-bearing along with the requisite case of assembly and disassembly. That the positive locking is an advance over the art is evidenced in that only the upright standards are needed for supporting the shelf structure without depending on additional back and base means.

In conclusion it is to be noted that the embodiments disclosed and described herein are meant to be illustrative only and not limiting in any sense. The embodiments described serve merely to illustrate the spirit and scope of the invention.
