Description

July 18, 1961 J. HUFF FOLDING RACK Filed Sept. 50. 1960 IN VEN TOR.

United States Patent 2,992,745 FOLDING RACK John Huff, 4243 W. Roosevelt Road, Chicago 24, 11]. Filed Sept. 30, 1960, Ser. No. 59,674 11 Claims. (Cl. 211-178) This invention relates to racks for holding records, files and the like and more specifically to an improved structure over the device in my US. Patent 2,892,548.

My improved folding rack is designed to minimize tooling and to provide an arrangement comprising separators extending between and pivoted to holders located at opposite sides of the rack, the connections between the holders and dividers being easily disconnectible so that various spacings between the separators may be obtained by removing or adding separators to the holders.

A further object of the invention is to provide novel connections between the holders and separators, the connections including lugs on the ends of U-shaped wire separators which are reversely angled to the plane of the separator and which enter into longitudinal grooves in the holders between a pair of opposed vertically spaced webs thereof to retain the separators and holders against relative vertical displacement, the lugs also serving as stops abuttable against vertical webs interconnecting the spaced webs to hold the rack squared.

A still further object of the invention is to provide a novel rack wherein the lugs on the ends of the separator wires are caused to swing out of the grooves of the respective holders and project toward the other holder as the rack is skewed and folded so that the lugs at one side of the rack enter the groove in the holder at the other side of the rack to releasably hold the parts in folded position.

The construction comprehends the provision of a plurality of inverted U-shaped dividers having dovrmwardly extending legs at opposite ends which enter vertical slots open at their upper and lower ends through upper and lower horizontal webs of channel shaped holders, the slots being open through the back side of the channel in a vertical web thereof so that the legs are entered and withdrawn transversely of the holder, the legs being held against withdrawal by retaining strips which enter behind the legs between the same and the vertical web and extend across the slots.

In extension of the previous object, the invention contemplates the provision of locking lugs at the lower ends of the legs which in the squared position of the rack swing under the lower web into a longitudinal groove developed between the lower web and a longitudinal flange reversely bent from the free edge of the lower web and projecting therebeneath and yieldably embracing the respective lugs for holding the rack in position.

These and other objects inherent in and encompassed by the invention, will become more readily apparent from the specification and the drawings, wherein:

FIGURE 1 is a plan view of my novel rack in use position, portions being broken away and shown in section;

FIGURE 2 is an end elevational view of the structure as shown in FIGURE 1; partially in section,

FIGURE 3 is an enlarged sectional view taken substantially on line 3-3 of FIGURE 1;

FIGURE 4 is a fragmentary top elevation of the rack in folded position; and

FIGURE 5 is an enlarged sectional view taken substan tially on line 5-5 of FIGURE 4.

Description of the invention Describing the invention in detail and having particular reference to the drawings, there is shown an upper divider or separator portion 2 and a bottom or basal tray portion 3 to which the separator portion 2 is mounted.

The upper portion comprises a plurality of inverted ice generally V-shaped spring wire dividers or partitions 4, each of which is preferably a round rod of steel or other resilient material and comprises an apex. 5 with downwardly diverging diagonal leg portions 6 6 which terminate in vertical end portions 7, 7', the lower ends of which are formed with reversely angled locking and holding lugs 8, 8'.

The end portions 7, 7', are entered through vertical slots 9, 9' in

upright walls

10, 10 into vertically aligned

notches

11, 12 and 11', 12 in the

inner edges

13 and 14 and 13, 14' of the top and bottom generally

horizontal flanges

15 and 16 and 15, 16 of the channel shaped holders generally designated 17, 17, the flanges and 16 projecting from the top and bottom edges of the vertical wall 10 and flanges 15', 16 projecting outwardly from web 10' respectively forming pockets 18, 18' therewith for reception of associated side elements 19, 19' of the base structure 3 whichmay include

transverse rods

20, 20 interconnecting the side elements 19, 19'. It will be understood that the

pockets

18, 18 preferably open outwardly and that the resiliency of the separators tends to maintain the holders yieldably against the respective side members. However, the holders if desired, may be assembled with the dividers in such manner that the pockets face inwardly.

The

lugs

8, 8 are disposed respectively beneath the

bottom flanges

16, 16 of the holders 17, 17', said

holders having webs

21, 21 respectively depending from the free edges of the

lower flanges

16, 16 and respectively merging into flanges 22, 22' which extend beneath the bottom webs 16, 16' of

holders

17, 17 and form longitudinal slots 23, 23' which respectively receive the

lugs

8, 8 therein in the functional or operative position of the rack.

Preferably the

flanges

22, 22 respectively pinch the

lugs

8, 8 with the

flanges

16, 16 to releasably hold the rack in open or operating position either partially skewed or squared particularly when the rack is being used as a file holder Without a base at which time the rack seats upon the bottom sides 25, 25' of

flanges

22, 22 which respectively are preferably spaced a distance from

flanges

16, 16 slightly less than the diameters of the lugs 8, 8'. The weight of the files between the separators when such files rest upon the holders further augments the holding action of flanges 22 and 22' against the

flanges

16, 16 by loading the holders so that the

slots

23, 23 tend to close.

The holders are retained in assembly with the separators by means of flat, substantially ribbon-like preferably sheet steel retainer strips 26, 26- which fit behind the

end portions

8, 8 against the

internal sides

27, 27 of webs 10, 10' and close the vertical entry ways or slots 9, 9' blocking escape of the

end portions

7, 7 therefrom.

In the construction of the lugs 8, 8' and their placement within the holders, the device features a novel arrangement for holding the rack squared in that lugs 8 abut the web 21 on its interior side 28 and lugs 8 simultaneously engage the interior side 28 of web 21 in the fully open position of the rack.

The lugs 8, 8-and

slots

23, 23 serve a further function in that as the rack is skewed as shown in FIGURE 4 the reverse relative rotation of the end portions 7, 7' swings the

lugs

8, 8 out of the slots 23, 23' and in the folded position the

lugs

8, 8 project endwise toward the holder 17' and likewise

lugs

8, 8, project toward the holder 17. In such position the bringing together of the

holders

17, 17 back to back enters lugs 8 into slot 23' and lugs 8 into slot 23 in the overlapped portions of the holders. The remaining lugs on the portions of the holders which are longitudinally displaced from one another project outwardly from the respective holders and lugs 8 align transversely lengthwise of holder 17 and lugs 8 similarly align with holder 17. This folding and ingenious arrangement of the lugs so that they align as aforesaid greatly facilitates packaging in a small flat carton and the structure is maintained rattle-free in shipment.

Thus a novel and eflicient device has been disclosed which can be modified various ways as will be well known to those skilled in the art and it is intended that such arrangements are to be understood as definitions of that specifically shown and described within the purview of the appended claims.
