STANDARD FOR SHELF ASSEMBLY Filed Sept; 9, 1965 INVEN R.

Attorney United States Patent 3,339,751 STANDARD FOR SHELF ASSEMBLY Martin Bard, 953 45th St., Brooklyn, NY. 11219 Filed Sept. 9, 1965, Ser. No. 486,033 7 Claims. or. 211-176) ABSTRACT OF THE DISCLOSURE Wall-mounted shelf standard having an upright channel-shaped bar with means for attaching shelf brackets thereto and a vertical sheath receiving the bar and having a pair of lateral vertical strips flanking the forward face of this bar with a width and a depth substantially equal to the width of the forward strips, a fastening bolt, screw or the like passing through mounting holes in the bar and a bridge portion interconnecting the strips, the strips having generally a triangular profile and forming oblique side faces including obtuse angles with the forward space.

My present invention relates to a wall-mounted standard of the type used to support bookshelves, display cabinets and similar projecting structures adapted to rest on brackets anchored to such standards.

A standard of this description generally consists of an elongated upright mernber, usually a metal bar, provided with a plurality of vertically spaced mounting holes for the passage of screws or the like along with other formations, such as short vertical slots, designed for engagement by mating formations on the shelf-supporting brackets to be secured thereto.

These uprights are sometimes regarded as unsightly attachments to their supporting wall and, by presenting lateral surfaces which include 90 angles with that wall, form dust collectors which cannot be conveniently cleaned by, say, a wall-dusting nozzle of a vacuum cleaner.

It is, therefore, an object of my invention to provide a standard of this description which blends more closely with the adjoining wall surface, not only for est-hetic reasons but also to facilitate cleaning.

When books or other heavy articles are shifted along shel-ves carried on such standards, they may strike the projecting side of the standard and, by the resulting impact, may loosen the screws by which the standard is held onto the wall. Thus, another object of my invention is to provide means for protecting the bracket-carrying member of such standards from lateral impacts of this nature.

Frequently a lamp, clock or other electrical appliance is placed on the uppermost shelf and must be connected by suitable wiring to an outlet near the base of the assembly. A further object of my invention, therefore, is to provide a standard of the character described which readily accommodates such wires in its interior, thus not only hiding them from view but also shielding them mechanically as well as electrically.

A standard embodying my invention comprises an elongated upright member which has a flat forward face forming a vertical land with the usual mounting holes and bracket-engaging formations and which further has a pair of lateral wings flanking this forward face, the wings defining a wall-contacting rear surface and being advantageously each of a width and a depth substantially equal to the width of the forward face.

The upright member may be a unitary body, eg of extruded resin or laminated sheet material, or may comprise a conventional perforated metal bar enveloped by a protective sheet which forms the aforedescribed lateral wings. These wings, in any case, will serve as a cushion for the bracket-carrying land and will absorb lateral impacts; they also may be made hollow so as to form upright channels in which electrical wiring or the like may be disposed. Particularly if these wings are of generally triangular profile so as to form oblique side faces which include an obtuse angle with the central forward face of the upright, dust collection is minimized and the exposed surface of the upright can be easily cleaned by Wiping or suction. Also, these oblique surfaces will tend to deflect oncoming objects for further protection against lateral shocks.

The invention will be described in greater detail with reference to the appended drawing in which:

FIG. 1 is an isometric view of a shelf assembly including a pair of standards according to the invention;

FIG. 2 is an enlarged fragmentary front-elevational view of one of the standards shown in FIG. 1;

FIG. 3 is a cross-sectional view taken on the line IIIIII of FIG. 2;

FIG. 3A shows, in a sectional view similar to that of FIG. 3 but drawn to a greatly enlarged scale, a small part of the structure shown in FIGS. 2 and 3; and

FIGS. 4-10 are views similar to FIG. 3, showing various modifications of the structure.

The shelf assembly 10 shown in FIG. 1 comprises a pair of

identical standards

11, 11 having brackets 12, 12' removably fitted thereon for the support of shelves 13. As more clearly shown in FIG. 3 for the member 11, each of these standards comprises an upright metal bar 14 with mounting holes 15 for screws 16 (FIG. 3) which are threaded into an adjoining wall 17 for firmly securing the upright 11 thereto. Bar 14 also has vertical slots 18 which are selectively engageable, in a manner known per se, by mating projections (not shown) of brackets 12 to hold the latter at a chosen level.

In accordance with an important feature of my invention, I surround the bar 14 with a protective sheath 20 having a pair of

lateral wings

21, 22 whose oblique surfaces define the sides of the generally trapezoidal proaccommodateelectrical wiring, eg as indicated at '19.

It will be noted that the depth and width of each

wing

21, 22 is substantially equal to the width of the perforated front face or land of bar 14 so that the entire standard 11 has a width equal to about three times the width of that face.

The wings 2 1, 22 are shown formed as rearwardly open strips of sheet material, of uniform transverse crosssection, interconnected by a bridge piece 25 integral therewith, the screws 16 passing through the bridge piece 25 which may be preperforated for that purpose or may be pierced in situ.

As illustrated more clearly in FIG. 3A, the body of sheath 20 is a laminate composed of an inner metal foil 26 and front and rear

outer layers

27, 28 of plastic material which may be suitably colored or transparent; in addition, a decorative covering layer 29 may extend over the front face of each

wing

21, 22 to simulate, for example, a body of grained Wood.

In FIG. 4 I have shown a modified standard 11a with a protective sheath 20a whose wings 21a, 22a, flanking the metal bar 14a, are of substantially square profile while still retaining the depth and width relationship de- 3 The same technique is used for the upright 11d of FIG. 7 where bar .14d is enveloped by an extruded plastic sheath 20d whose wings, however, have a partly convex rather than triangular cross-section.

In FIG. 8 I show an upright 11e wherein the bar 14e is enveloped by a laminated sheath 20e which differs from sheath 20 of FIG. 3 only by the fact that the wings 212, 22a terminate in integral extensions 21s, 22s overlying the forward land of bar 14e except for a central zone containing the slots and holes 15 and 18 (FIG. 2) thereof.

FIG. 9 illustrates a further modification in the form of a standard 11 made in a single piece, its laminated body of sheet material forming both a land 14f and oblique wing portions 21 22 including an obtuse angle with the land 14).

In FIG. 10, finally I show a standard 11g whose bar 14g has the flanges of its channel profile engaged by separate wing members 21g, 22g, again defining a generally trapezoidal profile with member 14g.

In those cases where the wings adjoining the perforated land of the standard include therewith an obtuse angle, preferably of about 135 (as in FIGS. 3, 6, 8 and 10) or slightly greater (as in FIG. 9), the oblique front surfaces of these wings will serve to deflect laterally oncoming objects so as to protect the mounting screws 15 against excessive impact. A certain degree of protection will, however also be afforded by the Wings of the other embodiments which, by virtue of their inherent elasticity, act as cushions against such lateral shocks. Except in the cases of FIGS. 6 and 7, ample space is provided Within the Wings for wires as shown at 19 in FIGS. 2 and 3; in the embodiments of FIGS. 35, 840, moreover, these Wires are kept away from the central region of the standard by transverse portions of the sheath so that there is no danger of contact with screws 16 or other fastening means.

It will be apparent that the profile of either the

solid sheaths

20c, 20d in FIGS. 6 and 7 or the unitary body 11 in FIG. 9 could be modified, e.g. along the lines of FIGS. 4 and 5, or that the sheaths of FIGS. 4, and 8 could be subdivided into separate wing members as illustrated in FIG. similarly, front extensions as illustrated at 21s, 22c of FIG. 8 could also be used on the sheaths of FIGS. 4-7 and 10. These and other modifications, readily apparent to persons skilled in the art, are intended to be embraced within the spirit and scope of my invention except as otherwise defined in the appended claims.
