March 9, 1965 A. J. HAVLIS DISPLAY RACK Filed Nov. 30, 1962 ATT INVENTOR ADOLPH J. HAVLIS United States Patent 3,172,376 DESPLAY RACK Adolph l Havlis, Williams Bay, Wis. Filed Nov. 31), 1%2, Ser. No. 241,404 6 Claims. (Cl. Hid-59) This invention relates to a new and improved display rack, and has for its principal object the provision of simpler and more economical, andyet far better, shelf supports than have been obtainable, the rack of my invention having coaXially aligned inturned end portions on the opposite ends of a plurality of horizontal rods which are easily insertable for pivotal mounting in vertically spaced holes provided in but not extending through the downwardly diverging legs of the tubular side frame embers of the rack, the legs being sprung toward each other to permit entry of these inturned ends in these holes and then spread apart to retain the same in said holes, a single bottom rod of generally similar form but having the coaxially aligned inturned ends somewhat longer than the first mentioned ones and threaded and extending all the way through the legs and having nuts threaded thereon to draw the legs together and complete the assembly. The advantages of this construction, aside from the simplicity and economy of construction already mentioned, are:
(1) There is no damage to the bright galvanized and lacquered finish of the tubing used in the side frame members as would follow from a welding operation, for example, and, therefore, the cost of an extra plating and polishing operation is saved, and a better looking display rack is the result since the tubing retains its original finish and luster;
(2) Whatever amount of projection of the shelves both from the front and from the rear of the rack is desired is easily provided for by corresponding elongation of the end portions including these inturned ends, merchandisers being eager to have the articles displayed as conspicuously on the shelves as possible, and this objective being so easily and nicely achieved with the present construction, and
(3) The present construction is sturdy enuoght so that no diagonally extending braces are required on either side nor even on the back of the rack, thereby leaving the merchandise on all of the shelves more easily accessible from all sides of the rack.
The invention is illustrated in the accompanying drawing, in which:
FIG. 1 is a perspective view of a display rack made in accordance with my invention;
FIG. 2 is an enlarged perspective showing a typical slip-in pivotal connection for both of the inturned ends of the shelf supporting rods for all but the bottom shelf; and
FIG. 3 is a similar perspective showing the related form of connection used for both ends of the rods for the bottom shelf.
The same reference numerals are applied to corresponding parts in these three views.
Referring to the drawing, the reference numeral 4 designates the display rack of my invention generally, the same comprising inverted generally U-shaped tubular side frame members 5 and 6 that are interconnected near the top and bottom at the back by a pair of horizontal tubular cross-pieces 7 and 8 having downwardly bent ends 9 secured to the inner side of the rear legs 10 of the side frame members by means of screws 11 entered through registering holes in the abutting parts and having wing nuts 12 threaded on their inner end portions. The frame thus provided serves to support a plurality of horizontal shelves 13-16 disposed in vertically spaced rela- "ice tion between the side frame members. Each of these shelves, which are all preferably made of sheet metal with upwardly bent front, back and side walls, as indicated at 17-19, respectively, has downwardly bent flanges 20 on the upper edges of the side walls 19 for support of the shelf at the opposite ends, the shelves being mounted on pairs of horizontal rods 21-24 carried on the side frame members 5 and 6. The rods 21-23 are all substantially alike, each having the opposite ends thereof bent to U-shape, as indicated at 25, so as to provide coaxially aligned inturned end portions 26, the extremities of which are pivotally entered in coaxially aligned holes 27 punched in the front wall of the front leg 28 of each side frame member and in the rear wall of the rear leg 11 the rods being all of the same length measured between their U-bends 25 but the inturned end portions 26 on the uppermost rod 21 being the longest, while the inturned end portions 26 on the next lower pair of rods 22 are cut slightly shorter, and the inturned end portions 26 on the next lower pair of rods 23 are cut still shorter, whereby to conform in dimensions between the cut off extremities to the diiferent spacing of the downwardly diverging legs 19 and 28 at the different levels and permit pivotally securing the three pairs of rods 21, 22 and 23 by means of the end portions 26 against endwise displacement when assembled for pivotal movement in the holes 27. The legs 10 and 28 of each of the side frame members 5 and 6 are sprung toward each other to permit assembling the inturned ends 26 in the holes 27, and these legs are thereafter spread apart to prevent endwise displacement of the inturned ends 26 from the holes 27, this being accomplished in accordance with my invention by punching coaxially aligned holes 27' all the way through the legs 10 and 28 so that the inturned end portions 26 on the lowermost rods 24 can be passed through the holes 27 and have acorn nuts 29 threaded thereon, these end portions 26' being threaded, as indicated at 311, for this purpose. Once the nuts 2% have been applied and tight ened so as to cause the legs 10 and 23 to be drawn together to a predetermined extent the rods 24 are, of course, fastened thereby quite securely and there is no possibility thereafter of either of the other rods 21, 22 or 23 becoming disconnected from the frame, even though there is a certain amount of freedom for both pivotal and endwise movement in all of these last mentioned rods.
in operation, despite the downward divergence of the legs 1!; and 252 of the side frame members 5 and 6, all of the rods 21-24 can be and are all of substantially the same length between the U-bends 25, and the shelves 13-16 can be and are all alike and adapted to be used interchangeably. The shelves are supported in vertical alignment to one another, the uppermost shelf 13 projecting to an appreciable extent both rearwardly and forwardly from the frame, and shelves 14 and 15 also projecting at the front and rear of the rack but to lesser degrees, as clearly illustrated in FIG. 1, while only the bottom shelf 15 has its front and rear ends disposed substantially flush with the front and rear of the rack. This projection of the shelves 13-15 is considered to be of great benefit in merchandising from the standpoint that the articles on display on the shelves, if placed as far forward as possible, are more conspicuous and hence more apt to attract the attention of the prospective purchaser and thereby increase the likelihood of sales. With the present construction, sales are further promoted because the articles on the shelves are readily accessible from all sides of the rack, there being no need in the present construction for any diagonally extending brace members on either of the side members 5 and 6 nor even between these members at the rear, Where the cross members 7 and 8 are provided in such close relationship to the bottoms of shelves 13 and 15, respectively, that they cannot interfere with the freedom of access to articles on shelves 1 5 and 16 therebeneath. The nice appearance of the tubing used in the side members 5 and 6 is in no Way marred by the punching of the holes 27 and 27', and all of the rods 2l24 can be assembled on these side frame members without any harm to the bright galvanized and lacquered finish by virtue of the novel construction and method of assembly described. With other constructions requiring Welding operations this of course is not possible, where the only way the damage to finish can be rectified is 'by an additional costly plating and polishing operation, the cost of which is saved with the present invention.
It is believed the foregoing description conveys a good understanding of the objects and advantages of my invention. The-appended claims have been drawn to cover all legitimate modifications and adaptations.
