Y invention flrelates to `a LEposting 1 stand and particulalrlyl 4'-to anffadjustable stand that may bekeptat any Idesired' height.

- Although 'the fstand "of "the present inventionisl'lcapable of general"`utility,`VV it iis' `'partici-ila'rly designedY to supporta lposting 'tray inconvenient positionfforeiicientI use -byfa clerk using :the-

tray. f Posting lentriesv =on: ledger f sheets `is generally dene by a clerksittingat a billing machine ortypewriter;r but a. person using a frposting "tray forireference often remains in standing position.y

Accordingly/it is `sometimes desirableto position the -trayfat a comparatively vlow-level, While at other-'times it must loefv positioned vat 'a higher levelifdrreflicient use'.I

It '-is"-an"ooje`ct of lvthisinvention 'to provide a posting fstand that may Akie-easily'adjusted to any desirable height and will supportthefload for which-itA isdesignedfiri'- any-'such position; It is another object 'of the invention to provide spring meansftocompensate for 'the-load supported on the -stand4 to facilitate the movement ofthe load supporting jpla'tform' in 'either'vertical direction. Another object 5is to provide an'operatiifig handle Withflatchmeanseiective to Ihold the stand at any *desired-height; and fmeans 'for 'quickly releasing-the-'handle lfor'"movenieritin either direction.; Other Solojects -of the invention will he come `apparent upon reading-thefollowing description-'taken in conjunction with'the accompanyingfdraW-ings, vin 'Which'r Figure l1 isaiside' *elevational view cra-posting stand "embodying 'the invention;

Therlatehing means fior holdingirtheplatfernr i4 at, any-.desired height; as showni ina Figure .25; comprises asplaten:slidablyzsecured tosthe.-` ban by means of a stud 3i which fits in an aperture 3i' provided in the bar 25 for that purpose. One end of the plate 39 is bent at right angies, to extend over the end of the adjacent sleeve 26, as indicated at 32. A stud 33 secured adjacent the end of portion 32 projects through apertures 34 and provided in the sleeve 29. The angular member 21 is also provided with an aperture 3B whichl is in registration with the apertures 34 and 35. The angular member 5, adjacent the latching means, is provided with a series of vertically spaced apertures 31 positioned at any desired height so that when the platform i4 is positioned at any desired height the stud 33 will be aligned with one of the apertures 31. A resilient strip 38, secured to the sleeve 25 by the pin 29, and one or more similar pins 38, has one end constantly pressing against the portion 32 to urge the stud 33 into latching engagement with the angular member 5. Thumb pressure exerted laterally against the button 3l holds the stud 33 outwardly of the angular member 5 so that the handle may be freely moved about its pivot 20. A stop member is provided on the upper edge of the angular member 5 to limit the upward movement of the operating handle.

The springs I8 exert a constant force urging the load supporting platform i4 upwardly, but the weight of the posting tray, for which the stand is designed, exerts a slightly greater force tending to compress the springs, with the result that the top section of the stand is generally in substantial equilibrium. Accordingly, when the handle is moved in either direction only a slight force is required, and when the latching means is in latching position the stud 33 is subjected to comparatively little strain. For this reason the stand requires latching means on only one side.

Although I have described a preferred embodiment of my invention in considerable detail, it will be understood that the description thereof is intended to be illustrative, rather than restrictive, as many details may be modified or changed without departing from the spirit or scope of my invention. Accordingly, I do not desire to be restricted to the exact structure disclosed, except as limited by the appended claims.

I claim:

1. A stand comprising a rectangular base member having an angular member projecting upwardly from each rear corner, an angular member projecting upwardly from each front corner, and a tubular post projecting upwardly adjacent each opposite edge of said base member at a point substantially centrally disposed relative to the length of said base member, a top section having a load supporting platform, angular members depending from said platform and slidably engaged with each of said front and rear angular members, tubular posts depending from said platform and telescopically engaged with each of said iirst mentioned tubular posts, a, compression spring positioned within each pair of said telescopically arranged posts, said spring exerting a constant force urging said load supporting platform upwardly, an operating handle pivotally secured to the rear two of said first mentioned angular members, said handle including a bar extending transversely in front of said front angular members, a plate mounted on said bar and slidable transversely relative thereto, said plate including an angular extension projecting rearwardly and spaced outwardly from one of said front angular members, said last mentioned front angular member having a plurality of vertically spaced apertures, and a stud projecting transversely from said extension, said stud being selectively engageable with said apertures to retain said load supporting platform in a plurality of predetermined positions of different heights.

2. A stand comprising a base member having an angular member projecting upwardly from each corner and a tubular post projecting upwardly adjacent each opposite edge of said base member at a point substantially centrally disposed relative to the length of said base member, a top section having a load supporting platform, a plurality of depending angular members slidably engaged with said first mentioned angular members, and a tubular post telescopically engaged with each of said iirst mentioned tubular posts, a compression spring positioned within each pair of said telescopically arranged posts, said spring exerting a constant force urging said load supporting platform upwardly, an operating handle including a pair oi levers each pivotally secured to a rear one of said rst mentioned angular members and a transverse bar slidably secured to the free end of each of said levers, means to maintain said transverse bar closely adjacent the front edge of said stand throughout all pivotal movement of said operating handle, and a latch mounted on said transverse bar, said latch being engageable with a front angular member to retain said load supporting platform in a plurality of different predetermined positions.

3. A stand comprising a base member having an angular member projecting upwardly from each corner and a tubular post projecting upwardly adjacent each opposite edge of said base member at a point substantially centrally disposed relative to the length of said base member, a top section having a load supporting platform, a plurality of depending angular members slidably engaged with said first mentioned angular members, and a tubular post telescopically engaged with each of said iirst mentioned tubular posts, a compression spring positioned within each pair of said telescopically arranged posts, said spring exerting a constant force urging said load supporting platform upwardly, an operating handle including a pair of levers each pivotally secured to a rear one of said rst mentioned angular members and slidably secured relative to one of said posts, and a transverse bar having its opposite end portions bent into sleeve formation to slidably receive the ends of said levers, and an angular strap slidably mounted on each of the front of the first mentioned angular members, said transverse bar being rigidly secured to each of said angular straps whereby the closely adjacent relationship between said transverse bar and the front edge of said stand is maintained throughout the pivotal movement of said levers.
