8 Claims. (Cl; 211-135) The presentinventionrelates to an improved tab'le constructionand more particularly, to a laboratory table unit having compact and closely fitting partswhich may be adjusted with respect to each other and readily used in an interfitting relationship with other similar units in order to rneet vari'ous or changing needs;
In arableand" particularly in awork-table; it is desirable to have a simple construction that involvesrelatively few p'arts and yet is practical, sturdy, and pleasing in appearancep in a work table, such as achemistry laboratory table, it is desirable to avoid above-table surface obstructionsand to minimize joints or gaps between the parts inwhich dirt, reagents, etc., may collect or through which they may leak. The last desideratum-is especially difficultto" achieve in-a work table having adjustable and interchangeableparts,since these features ordinarily entail'obstructions, additional seams, gaps, and the like.-
Ourtable satisfiestheforegoing desiderata by providing a unit or apparatus of simple a'n'd rugged construction in Whiohsurfa'c'e gaps, and theli-kei are substantially eliminated and searns are minimized, madeleak proof and tight; although the unit is adjustableas to. height and positioning of its parts and may be readily interfitted With' other'units to form a-lon'ger' or extended construction;

A table unit 10 of our invention employs amain or primary table top surface member or panel 13, a hacker apron surface member or panel12, and a smaller service tabletop or secondary surface member or panel 11 above and surmounting the apron-panel 12; these panels may be of a suitable corrosion-resistant material such asstainless steel.
We position support structure for the table 10 behind the apron surface 12, Where it may be secured to support all three surfaces in an assembled relationship; We avoid dirt, liquid, and chemical collectingseams, etc., by providing the secondary panel 11 with an upwardly projecting back flange 11b, by having the secondary surface 11 overhang theapron surface panel 12, by having the apron panel 12 overlap or overhang the primarypanel 13, by providing an improved side end or edgewise interfitting relationship between adjacent table units, by
providing an improved side edging, trim or cap construction for the prim'aryniember 13, and by providing the primary panel 13 with an underturned front edge or drip flange portion 13a.
The table unit 10 of our constructionis flexible, in that its parts are adjustably and interchangeably positioned to meet diverse requirements. Table leg, stanchio'nor support member assemblies provide a support structure that may be varied as to its length or vertical extent. The secondary panel 11 may be varied as to its horizontal positioning on the support structure (see arrow 11 of Figure 3) and the apronpanel 12 may bevaried as to its Vertical positioning, see arrow'b'ofth'e' same figure. Itwill be noted-thatthe apron panel 12 may be. vertically adjusted with respect to the primary panel lfiwvithout spoiling the lap-seal therebetween. The secondary panel 11 may also be'positioned forwardly and baclcwardly with respect to the panel 13* without breaking it's seating engagement with the apron panel12; The side edges or ends of the main table surface or primary panel 1-3 of the unit aredesigned to'interchangeably interfit end-to-end with tablesurface panels 13 of other similar adjacent units (see Figures 5 and6) or withtrim or'cap members 25 (see Figure 7);
Inthe formshown, our tablelt) makesuse of'end supportassemblies of loop shape, each'of which-has apair of spaced-apart vertical front and backlegs; posts or stanchions-14 -and'1'4. U-shaped'connectors 15 and 15 join-the upper and-lower ends-of the stanchions: Each connector 15'or 15 is adj'usta-bly mounted along its side portions to extend'itstransverse bight portion-a variable distance beyond the ends of the stanchions'and thereby alter their effective lengths.
The secondary or service pane-111 extends-between the bight portions of at leasta'pair of the connectors 15 at upper ends of the stanchions Maud-14'- and is-adjustably fixed to such portions for movement in the direction of its width, see Figure 3. The apron surface panel 12 has: a backwardly' projecting topflange portion 12a that seats or abuts against the flanged-f anunderlying front or for Ward portion lla of the service panel11= tol-ie substantially' flush therewith. The apron surface panel 12 is adjustablyfixed to front or inner. supporting 'stanchions 14 in order to be'moved in a-vertical direction to compensate for adjustments in the U-shaped. connectors 15 that join-the upper ends of the stanchions 14 and 14". y y
The primary or maintable surface panel lfi-issliown in "vertically-adjustable abutment'with the front'st'anchions 14" that carry the apronsurface' panel 12 to project out wardly therefrom. To avoid a back-splash seam or gap and to permit adjusting the apron surface panel 12 with respect to the primary panel 13 and vice versa, we pro vide a ship-lap type of sliding fit between an upwardlyprojecting back flange 13b and a downwardly-projecting forwardly-offset front flange 12b.
The main table surface panel 13 of each unit it) has channel-shaped connectors 23 at each side edge or'end to mate with similar connectors of a companion panel 13 of an adjacent unit. The connectors 23 extend transversely along the ends of the main table surface panel 13 or 13, see Figure 5. One connector 23 (of an adjacent pair) is spaced inwardly from the end of its panel, see panel '13 and extension portion 130 of Figures 3 and 5 and panel 13 and extension portion 130 of Figure 7A, and the other connector 23, see panel 13 of Figures 5, 6 and 7, projects outwardly from an adjacent or opposed .end of its panel.
Each back end support assembly for the unit (two are shown in Figure 1) comprises a pair of opposed stanchions or legs 14 and 14', the open or slotted sides of whose channel shapes face each other. Inturued flange feet 14a of each stanchion define a longitudinal or vertical slot along which the connector brackets 15 are adjustably clamped by bolt and plate amemblies 16. Each U-shaped connector bracket 15 has a pair of spaced-apart leg portions 15a and a connecting bight portion 15b to join upper ends of the stanchions. As shown in Figure 3, the plate of each assembly 16 is placed within the hollow portion of stanchion-s 14 or 14 and the bolts of the same assembly pass between the slots of the flanges 14a to draw the leg portion 15b into tight frictional engagement upon the flanges.
As shown in Figures 1 and 2, similar connector brackets 15' connect lower ends of the inner and outer stanchions 14 and 14'. The bight portions 15b of the lower connector brackets 15 may rest upon a support floor, while the bight portions of the upper connectors 15 carry the service panel 11 therebetween.
The service panel 11 has a forward portion 11a folded down and back towards itself to form a rearwardlydirected flange. At each end, the service panel 11 may be adjustably fixed to one half of the projecting bight portions 1512 by speed nut assemblies 17 which project through elongated adjustment slots 150 in such portions to cooperate with single or double plate washers (see Figures 4 and 8), so that the service panel 11 may be adjusted transversely in a substantially horizontal plane. If the panel 11 is an end panel, it may be secured through an outer set of slots 150; if it is to be used with the panel of an adjacent unit or with a trim member, it may be secured (as shown in Figure 3) to an inner set of slots 15c.
The apron surface panel 12 extends downwardly from the service panel 11 and is shown adjustably fixed to the front stanchions 14' by speed nut assemblies 19 (similar to 17) and a common vertical washer strip (not shown) that cooperates with vertically-elongated slots 14b in the stanchions 14'. The assemblies 19 are thus adjustable in a vertical direction. Like the panel 11, the panel 12 may be secured through the first or second group of aligned slots (1411), depending on whether or not an apron panel of an adjacent unit is to be used. As shown in Figure 3, the apron panel 12 has an effective edge sealing-off relationship with the panels 11 and 13 by reason of its top, backwardly-projecting flange 12a and its lower, offset lap-slide flange 12b.
The primary or main table surface panel 13 comprises a continuous sheet member which extends forwardly from the front stanchions 14' and from the apron panel 12 to terminate in the downwardly and inwardly-turned drip flange or front edge portion 13a, see Figure 1. A centrally-disposed and upwardly-open channel 20, a backwardly-disposed and forwardly-open channel 21, and a forwardlydisposed and upwardly-open channel 22 extend longitudinally in a transversely spaced-apart relationship with each other to support and reinforce the underside of the panel 13. As shown in Figures 1 and 5, end or connector channels 23 are mounted within the back side channel 21 to abut end portions of central or mid channel 20 and front side channel 22. The end channels 23 serve as connectors and at their inner ends abut stanchions 14'.
Although bolt and nut assemblies (corresponding to the assembly 29 of Figure 8) may be employed to secure back channels 21 to the stanchions 14 through verticallyelongated slots in the latter, I have shown the main panel 13 and its support members as a separate unit from the back structure and as having a vertically-adjustable interfi-tting relation with the back structure. Thus, as shown in Figure 2, leveling screws 30a of such an understand or cabinet as 30 of this figure may be adjusted by a screw driver from within the stand or cabinet to raise or lower each corner of the table panel 13 until it is fully level. Also, the panel 13 and its support members 20, 21 and 22 may be tilted upwardly from the front to lift the assembly away from the back structure, including panels 11 and 12 As shown in Figures 1, 5, 6, 7 and 7A, one end connector 23 of one panel 13 is secured forwardly of its end or side edge portion to either receive a projecting edge of an adjacent panel 13' or to receive top and bottom edges of a trim or cap member 25 (see Figure 7). The other end connector 23 of the same panel 13 (see Figure 7A) is secured behind the panel edge to receive a modified trim or cap assembly, comprising filler channel piece or member 25a and cap member 25. Each connector channel 23 (see Figure 5) has a series of elongated slots 23a along its side web or bight and a series of elongated slots 23b across its bottom or under flange. The former serve for mounting adjacent connectors 23 (see Figure 6) or a trim or cap member 25, see bolt, washer and nut assemblies 27 and 28, respectively.
As illustrated in Figure 8, bolt and nut assemblies 29 (speed type shown) may cooperate with slots 23b to secure the members 23 to a stand or cabinet 30 or as indicated by the dot and dash lines of Figure l, to the bight portion 15b of a front support leg or stanchion assembly that corresponds in construction to the back assemblies shown, but is of shorter length.
Whether a trim member 25 or an adjacent table top panel 13' is assembled with ends of the panel 13, a con struction is assured in which flush and edge-to-edge coplanar mounting is employed.
Referring particularly to Figure 2 of the drawings, we have illustrated an arrangement for bringing in plumbing, such as adjacent cold and 'hot water piping 31, to the apron panel 12. As shown, the piping 31 may extend out of the building wall 32, between stanchion or leg assemblies, upwardly along the thickness or depth spacing defined between the fore and rear stanchions 14 and 14, and then transversely out through a slot or hole in the panel 12, so that suitable fixtures may be mounted on threaded end portions 31a. Although the depth spacing between the wall 32 and the rear stanchions 14 may vary from nothing (close abutment caused by shortening the width of the back portion of panel 11) to a spaced relationship, such as shown in Figure 2, the spacing between the stanchions 14 and 14 is always available and sufiicient to provide service spacing for plumbing, electric wiring and other utility connections. Thus, the back member 12 may serve as an outlet panel for water, gas, electricity, etc.
The service or secondary panel 11 is ordinarily used for storing bottles of liquid reagents and the like. It is emphasized that throughout all adjustments of the panel 11, the flange 11a seats against the flange 12a and, as shown in Figure 1, provides a drip edge that may be readily washed or wiped 011. When there is spillage of liquid reagents on the service panel, the liquid (for exmeans am le, acid) will run or drip off the panel 11 upon the panels-12 and 13, thus protecting the joint between the portions Ila-and 12a.
When it is desired to lengthen the table or unit 10, :anothersimilar table unit may be readily interfitted with the first, as illustrated. It will be noted that the stanchions 14 and 14' and connectors 15 of one so-calledservice or support island may alsoserve for mounting adjacent panels such as 11, 12 and 13 of the added unit in-a flush, edge-to-edge and substantially coplanar relationship with corresponding panels of the other adjacent-unit. Ordinary bolts and nuts, self-tapping screws or bolts, or speed nuts, all'of which are known in the art, may be used. Any seams between adjacent units may be filled with 'solder or a water-tight inorganic cement to provide fully continuous surfaces.
If it is contemplated that only a single section or table surface u-nit is needed, then the end connectors 23 for the unit may be mounted to project outwardly (as shown to theleft of Figure 1) from opposite ends of the mainor lower surface panel 13. However, we-prefer to have one end connector 23 mounted to project outwardly (see-Figure 7)v and the opposite end connector 23 mountedina depressed or inwardly offset or spaced relation (see figure 7A) to make the unit of panel 13 more readily adaptable for combining with additional units. It is apparent that the cap members 25' may be used toenclose both ends of each unit, but that oneor both of the cap members may be removed if it later appears advisable to add one or more adjacent units to one or both ends of the existing unit. A companion unit of similar construction may thus be mounted in position in such a manner that the projecting connector of one unit cooperates with the inwardly spaced or ofiset connector of another unit to provide a fiush, hair-line seam between end-to-end positioned main surface panels 13 and 13 of the units.
It is thus apparent that table units 10 of our construction are highly adaptable to meet requirements as they may arise. The connectors 23 and the other channel or support members 20, 21 and 22 may be soldered or spotbrazed in position on the underside of the panels 13 or 13' to provide a unitary main panel or table top construction. The desideratum is to provide transversely-extending connectors 23 for the panels 13 and 13' of adjacent units 10 which may be secured together by bolt means 27 of Figure 6 and which will provide single-surfaceplane, edge-to-edge, and effective sealing seams between the edges of adjacent panels 13 and 13', as well as a support for the projecting portion 13c of the one panel 13' on the upper flanges of both of a pair of adjacent or abutting connectors 23.
