Definitions

  • the shelving devices of the specified U. S. Patents require that the support tubing be provided with grooves at predetermined intervals in order to be engaged by a projection extending from a support member. Such scoring is somewhat costly in the case of round tubing and most likely prohibitive in the case of square tubing. Furthermore, the shelving systems of U. S. Pat. Nos. 3,424,111 and 3,523,508 can be located only as allowed by the grooves in the support posts. Also, an unscored piece of tubing is believed to present a much more satisfactory appearance than a tubing with spaced notches. Furthermore, scored tubing is weaker mechanically than unscored tubing, and the shelving itself provides a collection area for unwanted dirt and grime.
  • adjustable shelving which combines the advantages of a wedging support, and yet also includes the simplicity of the set screw support.
  • Yet another object of the present invention is to provide adjustable shelving wherein the weight of the shelf and any articles placed thereon serves to strengthen the securement of the shelving to the uprights, but wherein such shelving can be moved upwardly by a single tap.
  • Still another object of the present invention is to provide adjustable shelving that can be quickly assembled, using a small number of parts, and wherein the position of each shelf can be quickly changed in a relatively simple manner.
  • Yet another object of the present invention is to provide adjustable shelving that can be manufactured at a relatively low price, and yet will support a considerable load.
  • each piece of shelving including shelf collars at the corners thereof.
  • Each upright is provided with a shelf support that is secured to the upright by a tightening screw with the outer surface of a shelf support tapering outwardly downwardly.
  • the shelf collar has an interior surface that also tapers outwardly downwardly with the shelf collar being fitted upon the shelf support and held in place by the shelf support.
  • FIG. I is a perspective view of adjustable shelving constituting a first embodiment ofthe invention.
  • FIG. 2 is a greatly enlarged view taken along the lines 2-2 of FIG. 1;
  • FIG. 3 is a sectional view taken along the lines 3-3 of FIG. 2'.
  • FIG. 4 is a sectional view taken along the lines 4-4 of FIG. 3;
  • FIG. 5 is an elevational view of a shelf support used in the practice of the adjustabh shelving of FIG. 1;
  • FIGS. 6 and 7 are vie'ws taken along the lines 6-6 and 7-7 of FIG. 5;
  • FIG. 8 is a sectional view taken along the lines 8-8 of FIG.
  • FIG. 9 is an elevational view showing a second embodiment of the present invention.
  • FIG. 10 is a sectional view taken along the lines Ill-I0 of FIG. 9;
  • FIG. I1 is a sectional view taken along the lines II-Il of FIG. I0;
  • FIG. 12 is a perspective view showing a shelf support that is used in connection with the second embodiment of the invention.
  • FIG. 13 is a rear elevational view of the shelf support of FIG. I2;
  • FIG. 14 is an elevational view showing a third embodiment of the invention.
  • FIG. I5 is a sectional view taken along the lines 15-15 of FIG. I4;
  • FIG. 16 is a sectional view taken along the lines 16-16 of FIG. 15;
  • FIG. I7 is a plan view showing the shelf support used in connection with the third embodiment of the invention.
  • FIGS. 18 and I9 are sectional views taken respectively along the lines 18-18 and 19-19 ofFIG. 17.
  • the adjustable shelving I0 includes ground engaging uprights 12 which possess adjustable feet 14. Closure caps are inserted at the open upper ends of the uprights I2.
  • the uprights l2 serve to support two shelves I6, although the number of shelves used in connection with the present invention has no theoretical limit.
  • each of the shelves I6 includes at each corner a generally circular shelf collar 18 that defines a circular opening I9 that is actually conical in shape with the interior surface of the shelf collar 18 tapering outwardly downwardly for a purpose that will be discussed hereinafter.
  • Each of the uprights I2 of FIG. I may be standard metal tubing, the outer surface of which is not scored or grooved in any way.
  • the other components usable in connection with the adjustable shelving of the invention are of a metallic material.
  • metals or plastics which will occur to fliose skilled in the art.
  • the metal will be rust resistant or will contain a rust resistant coat ing.
  • the uprights I2 are preferably made from tubing that is hollow in order to save weight and expense, although there is no reason why solid tubing cannot be used.
  • shelf supports 20 In order to secure the shelving 16 to the uprights I2, it is necessary to use shelf supports 20 as shown in FIG. 5. It will be seen that the outer surface of the shelf support 20 tapers outwardly downwardly in order to receive a shelf support I8, the interior surface of which also tapers outwardly downwardly. It will be appreciated that when the shelf collar 18 is positioned about the shelf support 20 that the shelf collar I8 will tend to contact the shelf support 20 in a wedging manner in order to make a tight joint. However, such joint can be easily dismantled by a simple upward tap on the shelving 16.
  • each shelf 16 is composed of side frames 22 that are joined to end frames 24.
  • Cross-rods 26 extend between the frames 22 and long rods 28 extend between the end frames 24 in order to provide a load bearing surface.
  • the shelves may also be made of sheet metal or other standard forms.
  • the shelf support 20 includes fingers 30 that extend upwardly from the flange 32.
  • the fingers 30 are defined by a slit 34 which grows wider as the flange 32 is approached.
  • a tightening screw 36 passes through the flange 32.
  • the slits may be of constant width or grow narrower as flange 32 is approached.
  • the shelf 16 will still be held by the support 20 by virtue of the wedging action of the shelf collar 18 upon the shelf support 20 which creates an inward pressure upon the upright 12 by virtue of the resiliency of the fingers 30.
  • FIGS. 9 to 13 A second embodiment of the invention is shown in FIGS. 9 to 13 wherein square tubing is utilized for the upright IZ-A.
  • the shelf collar 18-A is also square.
  • the interior surface of the shelf collar l8-A is tapered outwardly downwardly.
  • the shelf support 20-A(FlG. includes two walls 38 surface extend upwardly from flange 40 with a hole 42 (FIG. 13) being provided to allow the passage of tightening screw 42.
  • FIGS. 15 to 19 A third embodiment of the present invention is shown in FIGS. 15 to 19 wherein the shelf support has four upstanding fingers 38-B instead of the two walls of FIG. 12. It is noted that the upright 12-3 is of square tubing and that the shelf support is simply slipped over the upright lZ-B. The outer surface of each of the upstanding fingers 38-8 of the shelf support is tapered downwardly outwardly in the same way as the outer surface of the two walls 38 of the shelf support 20-A of FIG. 12.
  • shelf support Once the shelf support has been secured upon the upright l2-B by tightening of the screw 42-8 that passes through flange 40-8, the shelf is simply lowered upon the shelf support so that each shelf collar lS-B is seated upon a shelf support.
  • the interior surface of the shelf collar l8-B is tapered outwardly downwardly so that the shelf collar will seat in a very snug way upon the shelf support.
  • the shelf support included resilient fingers so that the wedging action of the shelf collar against the shelf support serves to urge the fingers into frictional contact with the outer surface of the uprights.
  • both the interior surface of the shelf collar and the exterior surface of the shelf support were tapered to a Morse taper of about H6.
  • Morse tapers are widely used in machine shops and provide not only accurate alignment between the parts but also considerable frictional resistance.
  • each shelf collar about a shelf support in view of the outwardly downwardly taper of both the interior shelf collar surface and the exterior shelf support surface. It is preferred that the slope of both of the aforementioned surfaces be essentially the same so that the shelf collar will be received in a snug fit.
  • Adjustable shelving comprising a plurality of shelves supported on ground engaging uprights having a continuous, unscored outer surface, each shelf including shelf collars, each upright being provided with a unitary shelf support that is secured to the upright by engagement of a tightening screw which is in firm contact with the unscored surface of said uprights until at least the time said shelf collar is fitted upon said shelf support, the outer surface of the shelf support tapering outwardly downwardly, the interior surface of each shelf collar also tapering outwardly downwardly with said shelf collar being fitted upon said shelf support and held in place by said shelf support.
  • each shelf support includes upstanding resilient fingers that are urged into contact with said upright by the inward pressure created by said shelf collar when seated upon said shelf support.
