Background of the Invention
Various types of display rack clips have been proposed such as shown in U.S. Pat. Nos. 3,967,346, issued July 6, 1976; 3,498,469, issued Mar. 3, 1970; 3,310,179, issued Mar. 21, 1967; 3,223,095, issued Dec. 14, 1965; 2,677,468, issued May 4, 1954 and 2,532,021, issued Nov. 28, 1950. All of these prior art devices however utilize clips which are separately formed from the support, are costly to manufacture, must be individually assembled and are subject to malfunction and loss of the individual parts.
Summary of the Invention
The present invention provides an integrally formed spring clip support having an elongated steel support member from which resilient clips are partially punched and thus integrally formed therewith. The clips include an intermediate arcuate portion integrally attached to the steel support and which act as a pivot point for the clip and resiliently urge the clip into article contacting position. The clip is formed simply by the stamping or punching operation, need not be assembled separately on the support and cannot malfunction due to improper assembly or looseness of the clip. Another aspect of the invention relates to an integral spring clip support assembly including a pair of channel cross-sectional shaped, elongated steel support members arranged together to form a rectangle in cross-section support having the above-mentioned integral spring clips formed along opposite sides and along its length. A still more limited aspect of the invention relates to such a support assembly having means for firmly holding the vertical support in a base member. The invention furthermore contemplates the use of a connector between the two channel shaped members whereby the latter can be easily snapped and held together in assembled relationship.
This and other objects and advantages of the present invention will appear hereinafter as this disclosure progresses, reference being had to the accompanying drawings.

Description of a Preferred Embodiment
Referring to FIG. 1, the spring clip support assembly includes a base 1 preferably made of plastic and of generally rectangular form in plan. Along opposite sides of the base are male and female inter-engaging members 3 and 4, respectively, which are clearly shown in FIGS. 3, 6 and 7. Member 3 is comprised of an outwardly extending projection of dovetailed shape while member 4 is a complimentary shaped recess in which a male member 3 of an adjoining base can be slidingly engaged. Thus a series of bases can be firmly attached to one another to form a series of support assemblies.
The assembly shown in FIG. 1 also includes a pair of upwardly extending, elongated steel support members 5 and 6 which are each of channel cross-sectional shape and each having pairs of longitudinal edges 5A and 6A, respectively, (FIG. 2) which abut against one another to thereby form a rectangle in cross-section support member indicated generally by the numeral 7. This rectangle in cross-section support member is insertable into a central opening 10 (FIGS. 1, 2, 5, 6) of rectangular shape in the base 1, as will more fully appear in detail later.
A series of integrally formed spring clips 11 are formed along the length of the support members 5 and 6 and are spaced apart from one another as shown for individually releasably supporting article A to be displayed, such as, for example, bags of potato chips. The chips 11 are partially punched from the substantially flat side 12 of the support members. The clips have a lower article engaging end 13 and an upper, finger-operated end 14. The clip also includes an intermediate arcuate portion 15, one on each side, and which are integrally attached at 15A to the support member. It will also be noted that the clip 11 has a raised portion 11A stamped along its length to thereby make it more rigid. The clip is formed by punching from the support member as mentioned, and the lower article engaging end 13 is normally in an inner position adjacent the flat wall 12 to thereby grasp the edge of the article A between end 13 and the substantially flat side on the support member 5. As indicated in FIG. 10, when the upper, finger-operated end 14 is pushed inwardly towards the support member as indicated by the arrow, the lower end of the clip is opened to receive the article A. When the end 14 is released, the spring portion 15 acts to return the clip to the engaged or closed position. It will be noted in FIGS. 8, 9 and 10 that a pair of projections 18 are also punched from the flat side 12 and which act, the combination of the clip end 13, to hold the article firmly in place and prevent its accidental withdrawal.
For the purpose of firmly holding the support member 7 in the opening 10, a U-shaped plug 19, also preferably formed of plastic, is inserted into the opening 10. This plug has a pair of spaced apart, upwardly extending free legs 16 and 17 over which the rectangular support member 7 is slipped when being inserted into the opening 10. The channel shaped supports 5 and 6 can be separately inserted into the opening 10, for example, support member 5 can be inserted first and then a tapered wedge 20 (FIGS. 2 and 5) can be inserted tightly between the legs, urging them apart. The other support member 6 can then be inserted in the opening and the combined support member 7 is thus tightly and frictionally held in the opening.
For the purpose of holding the supports 5 and 6 tightly together along the length, a connector 25 (FIGS. 3 and 4) is inserted between the members 5 and 6 and the protruding dowels 26 of the connector 25 are inserted in aligned holes 27 of support members 5 and 6. Thus the members 5 and 6 are snapped over the dowels 26 and are frictionally held together by the connector 25 snugly engaged therebetween.
As shown in FIGS. 11 and 12, a double stack arrangement is shown wherein two pairs of channel shaped support members or posts are mounted one on top of another by means of an extending connector or plug indicated generally at 35. The plug 35 is actually a pair of plugs 19 shown in the other figures but which have been glued together along their adjacent surfaces or glue line 37. In this manner the capacity of the assembly can be doubled without utilizing any additional floor or shelf space.
Referring to FIGS. 13 through 16, a hanger type support assembly is shown wherein the support post or member is hangingly suspended rather than utilizing the base 1. The support member is suspended by means of the L-shaped hook 40 which has an upper double dowel 41 which is engageable in corresponding holes 27 in the upper end of the support member. A sign 43 can also be secured on the dowel member 41 as indicated. The hook also has a hole 45 by means of which it can be suspended on a nail or other projection (not shown).
