:ATTORNEY Units fiarss "Qiics Claims. (Cl. 243-120 This invention, relates in general to pallettiering frames.

and, more particularly, to frames of such character with uprights located outside the 'load-bearing'area of the pallets. This application is a continuation-in-part of our co-pending applications Serial Nos. 420,948, filed April 5, 1954, nowvPatent No. 2,828,932, dated April 1, 1958, and Serial No. 548,097, filed November 21, 1955, both being entitled Pallet TieringFrames, now Patent No. 2,828,933, dated April 1, 51958.

It'is an object of this invention to provide a pallet tiering frame comprised of a pair of identical sections having means for readily detachable, snap-fitting engagement upon the stringers of a pallet, whereby the uprights will be disposed beyond the periphery of the pallet, so that said pallet tiering frame may be engaged upon a pallet after the same has been fully loaded.

Another object of this invention is to provide a pallet tiering frame of the type stated which may be readily adapted to present the uprights either adjacent the sides or the ends of the pallet in order to selectedly permit unobstructed load-handling along the sides or the ends of the pallet.

, It is an additional object of the present invention to provide pallet tiering frames of the type stated having.

normally inwardly biased uprights whereby the same in operative position will be stressed for stabilizing engagement upon a pallet..

. It is a further object of the present invention to provide pallet tiering frames which incorporate novel means for transmitting the load imposed upon one frame to the up rights .of the underlying frame or frames in the particular tier.

It is a stillfurther object of the present invention to provide pallet tiering frames which may be adapted for use with any size or type palletrwhich may be fabricated most economically; and which are durable and reliable in usage. I

,Other objects and details of the invention will be apparent from the following descriptiomwhen read in connection with the accompanying drawings wherein:

Figure 9 is a perspective view of a pallet tiering frame unit inunmounted or detached condition.

Figure 10 is a plan view of a pallet tiering frame of the present invention having another form of interlocking means.

In the drawings, 1 designates a conventional storage pallet having parallel side or outer stringers 2, 2' and a central or inner stringer 3, and upper and lower decks or platforms comprised of spaced, parallel boards 4, 5 respectively, in axially normal relationship to

stringers

2,2, 3, and being suitably secured thereto, as by nails. It is to be pointed out that pallet 1 is not considered a part of the present invention, but is. merely representative of storage pallets in general, and although being illustrated as of the double-deck, flush stringer type, may, if.

desired, be of single-deck design, as well as having either flush or inset stringers.

Provided for detachable installation upon pallet 1 a tiering frame, indicated A, comprising a pair of identical component units 6. Each unit 6 includesapair of posts or uprights 7 for disposition proximate adjacentcorners of pallet 1; there being at the lower end portion of each post 7 a stringer-engaging foot member 8.

Secured to the upper end of each post 7 is the outer end" portion of a leg 9 of a generally U-shaped top member 10 being fabricated preferably of pipe stock and disposed in planar-parallel relation to pallet 1. At their ,outer ends, each leg projects a short distance beyond the point of securement to the associated upright 7 to provide a bearing extension 11, and at their inner ends, each leg 9 is continuous with an intermediate connecting section 12 having fixed therein a relatively long pin 13 projecting toward the opposite side of pallet 1 to that upon which the'related unit 6 is mounted, that is, in substantially axially parallel relationship to deckboards 4, 5. Provided adjacent each pin 13 is an axially parallel aperture .14

of comparable diameter to pin13 for snugly receiving the pin of the opposite unit. Since the component units 6 of frame A are identical, the pin 13 of one unit will be aligned with the aperture 13' of the other unit when said units are mounted on pallet 1, whereby the same may be interengaged in their top members 10 with abutment between the respective connecting sections 12' for mutual reinforcement to complete formation of frame A and firmly establish same for load support.

The foot member 8 at the lower end of .each post 7 constitutes a generally U-shaped bracket, fabricated of suitable sheet stock, comprising

parallel side plates

14, 15 and an interconnecting Web 16 in planar perpendicular The foot members 8 of the posts of each unit open toward each other for embracing the opposite end portions of the

intervningside stringer

2, 2, as the case may be. In engaged position on a stringer 2 or 2', the web 16 of a foot member}; will abut on its inner face against the end face of the stringer, with

side plates

14, 15 presented respectively adjacent the outer and inner side faces of the related stringer. The distance between

side plates

14, 15 should desirably be such as to abut against the confronting portions ofthe stringer, but contact is not requisite to provide stability of the units 6 laterally of the associated stringer. The height of foot members 8 is less than the space between the upper face of the lower deckboards 5 and theunder 7 face of the upper deckboards 4 to permit vertical slid-' ability with respect to the related stringer for'purpose's- 'to' form a stable, unitary support system. 7

As illustrated in Figures and-"8, the bearing memberby the posts 7 of the two units 6' will be aligned with the; adjacent ends of the side stringers 2, 2' and hence'dis-' posed beyond the end margins of'pallet 1, whereby the sides of pallet I are unobstructed, being open their entire length, for unimpeded. movement thereacross of loads to and from pallet 1. Furthermore, with posts 7 being presented beyond, or outwardly vof, the periphery of pallet 1, the full surface area thereof is available for loadreceiving purposes, being undiminshed by any portion of pallet tiering frame A. a

'With respect to the form of the present invention illustrated' in'FigureS-S and 6, it will, be' seen that posts 7 may, ifidesired; be secured to the outer face of side plate 14 of the relatedfoot member 8' whereby posts 7 will be presented beyond the outer side face of the associated stringers so as to present the end margins of pallet 1 in unrestricted fashion for end loading and load-removal. Posts Tof'each unit are resilient about their point of securement to their respective top member 10 forIrelative movabil'ity in a substantially horizontal direction and arebi'ased toward each other or inwardly of the end edges of the pallet, as may best be seen in Figure 8. Thus, to mount a tiering frame unit 6'. upon a pallet it is necessary to applytoutwardly. directed pressure against 7 theposts'7 to force same away from each other, beyond the pallet end edges in order to present their foot members Sfor engagement upon the ends of'the side stringers bottom edges of its bearing members 17 will rest upon such support'surface; thusthebottom edges-of the said bearing members 17 and the bottom face of the lowermost pallet will be coplanar, with the respective foot members 8 embracing the ends'of the adjacent stringers at po t relatively l vated. above those at which the foot members 8 of the upper'pallet tiering frames engage h p -strin er It is'inanit stthar the height of 2," 2'; with foot members being; snapped, or sprung, into 7 engagement upon the stringers upon release-of, the outwardly'di'rected' pressure on posts 7. Said posts are hence, stressed when in operative position whereby a snug,

surface-abutting contact is established between the web 16 of foot members 8 and the end faces of the side stringers, rendering component units 6 sturdy and. re: sistant to displacement. I

Each post 7' at its lower extremity, spacedly below its respective foot member 8, carries a short, downwardly opening, concave bearing member 17, which is axially perpendicular to its related post 7 and axially parallel- 10,: and substantially coextensive with, the bearingextensiqn ll'adjacent the upper end of 'said post 7. Each bearing member 17"is formed. on a slightly greater radius than that ofjthe' pipe stock from which bearing extensions 11' and, hence," top members 10 are fabricated.

Referring to Figure 8, it will'be noted that when p'aljlets 1," are 'tieredby use of the present invention, the

bearing member 17 of an upper pallet tiering frame will seat upon the proximate bearing extension 11' of 'the' pallet tiering frame immediately therebeneath, with the slightly increased radius of bearing member 17 assuring the formation of a firm joint.
