Int. Cl. A m 57/08 US. Cl. 108-64 7 Claims ABSTRACT OF THE DISCLOSURE Demountable shelving having vertical columns with horizontal shelves and clips engaged in recessed portions of the columns and beneath the shelves.

BACKGROUND OF THE INVENTION Field of the invention This invention pertains to shelving, and more particularly, to shelving of the type adapted for assembly and disassembly to provide variant horizontal and vertical combinations of elements.

Description of the prior art SUMMARY OF THE INVENTION The present invention provides shelving of the type described above which is adapted for ornamentation to provide an assembly of visually pleasing effect as required for use in ofiices, homes, and other non-industrial areas.

A basic objective of the present invention is to provide shelving characterized by stability of connection and adapted for rapid assembly and disassembly.

A further objective is to provide shelving of this type which is of simple outline and wherein the connection elements are so arranged as to be substantially hidden in use and wherein diagonal reinforcing elements are made unnecessary.

A further objective resides in supplying shelving of the type indicated wherein ornamental facing members may be joined to the vertical supporting columns following installation of the shelving.

Still another object is to provide shelving of the type indicated wherein the shelving may be connected in series and wherein the vertical spacing of the horizontal shelves is variable.

Related to the objective of increased stability in use, is the concept of supplying a shelving connector which embodies a spring tension connection between the assembled elements.

Other and further objects and advantages of the invention will become apparent to those skilled in the art from a consideration of the following specification when read in conjunction with the annexed drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings in greater detail, in FIG- URE 7 a completed assembly A comprising a typical embodiment of the present invention is shown. The assembly A includes a plurality of upright columns 1 supporting substantially rectangular, horizontal shelves or trays 16. The arrangement of components is such that the shelf 16 may be positioned at a number of different locations on the columns, and the units may be connected in a longitudinal series, as appears in more detail hereinafter.

The columns 1 best shown in detail in FIGURE 1, are preferably formed of metal and include opposing, flat side walls 5 and 6 with inwardly projecting forward walls 5a and 6a extending toward one another therefrom to define an elongated, vertical opening 2 of substantial width. Opposite the forward walls and opening is a multi-part inner wall including a U-shaped central portion with a bight section 3, and arms 3a and 3b. Flanges 3c and 3d connect the arms and the side walls 5 and 6.

The bight section 3 has a continuous series of substantially equi-distantly spaced apertures 4 formed therein and arranged in transverse alignment with the opening 2. The provision of the openings 2 permits access to the interior of the column which is necessary for effective tightening of changeable fasteners (described below) in the mounting of the columns and shelves, and additionally permits the connection of exterior finish panels (not shown) which are connected thereon at the walls 5a and 6a by any one of a number of known means.

In FIGURES 1 and 2, a first form of mounting member M is shown. The mounting member includes a pair of substantially right angularly related, horizontal arms 7 and 8 of rectangular form, and an attachment clip. The clip has a leg member 9, a step member 11, and a vertical arm 11a, and in FIGURE 2 it is seen that the arm 7 is arranged to deviate at an angle of approximately 2 to 5 degrees from the horizontal with respect to a line normal to the vertical axis of the leg 9, for a purpose appearing below. The leg 9 and the horizontal arm 8 each have an internally threaded opening 10 formed therein, and these openings are spaced coequally with the spacing of the apertures 4 in the column 1.

FIGURES l and 5 show the manner of securing the mounting member M on the column 1. A selected height is first chosen for the shelf 16 to be mounted, and the openings 10 of the mounting member are aligned with the selected pair of apertures 4 on the column. A bolt 10a of selected length or other changeable fastener is then extended through the aligned apertures and engaged in the threaded openings 10access being had through the open space 2. It is to be observed that the width of the legs 9 is such that the leg is encased between the arms 3a and 3b of the bight portion. Further, the spring effect of the tightening of the fasteners 10a against the inclination of the arms 7 when connected with a shelf as described below maintains a constant pressure on the clip resulting in additional rigidity of connection.

It will be understood that the mounting members M which form the corner supports in the connection of shelves 16 on the columns 1, are provided in opposite hand orientations, right hand and left hand, respectively, for each end of the shelving.

FIGURES 3 and 6 disclose a modified form of the mounting means herein designated M-l employed as an intermediate connection where a series of shelves are employed in side-by-side relation. Here, two pairs of horizontal arms 12, 13, the arms 13 being arranged at shallow upward inclinations, are provided and are supported by a clip having a depending leg 14 of greater length than the leg 9, and having a pair of openings 14a therein for alignment with the apertures 4. The clip further includes a step member 15, and a bifurcated vertical arm 15a for connection of the horizontal arms 12 and 13. The mounting member M-l is secured to the column 1 by changeable fasteners which may, optionally, include bolts 10a and nuts (not shown).

The shelves 16 hereof may be either plain or suitably ornamented and have flat top sections with depending front and rear walls 17 and side walls 18. The walls 17 have inward horizontal flanges 17a which terminate at a location spaced from the end walls 18, and the walls 17 have a hole 17b therein alignable with the uppermost one of a pair of openings and apertures in the mounting mem bers and columns. Thus, with the components assembled as shown in FIGURE or FIGURE 6, a fastener may extend additionally through the shelf for added security of connection. It will be additionally seen in those figures of the drawing that the flange 17a underlies the arm 8 or 12, thus ensuring the shelves against inadvertent displacement vertically.

Having described and illustrated the invention in some detail, it will be understood that these descriptions and illustrations have been offered only by way of example.
