Abstract
Abstract of the Disclosure A drawer incorporates wall panels having cavities in their ends and connecting members connect the wall panels to adjacent wall panels. Each of the connecting members have projecting spigots for engagement in the cavities of the associated wall panels. The connecting members are provided with interference projections positioned and dimensioned to prevent complete engagement of the connecting members with the panels other than in the correct position.
Description
S~ Z
The inventi~n relate~ t~ c~rnpon~nts for use in the construction of c~ wers.
Drawer constructioni are kn~wn in ;~hich at Least th~-si~ nd back ~alls of the d~aw~r ore formed from extruded pl~lstic ~ nels of hollow prof.ile int~r~onnecte~ t ri~ht ~n(lles to one ~nother ~y c~rner pi.e~:~s h~vinl~ sF).i(3ot portions wtlich project theref~orn i.n two dil~ctiorls ~It r:i(3ht ang.l~s ond enl~agt within the hollow open ~nds o~ the p~:~n~ls. The sF)igots rnay l~e r~tained ;.n position in the ~n~s of the panels by menrls of c~dhesive or by pro,jectin~ detents ~/h.ich sn~p into holes formed acljacent to the ends of the pa~els In drawer constructi.ons of this kind it frequently h~ perls that the corr~r pieces ~lre capable of bein~ inserted or partially inserted in-l;o the encls of the panels in arl incorlect position resull:in~ in incorrect asse~nbly of the drclwer, and it is an obj~ct of the present :i.nv~ntion to provicle means whereby inc,orrect ass~mbly. of this ki,nd rnay be avoided, The invention provides a drawer including at least a back wall and side walls which comprise wall panels having cavities in their ends and connected to adjacent wall panels by connecting members ha~ring projecting spigots for engagement in said cavities, the cor,necting members being provided with interference proj~ctions positioned and ~imensioned to prevent complete engagement of the connecting members with the panels othe.r than in the correct. position~
~ t least one of saic. interference projections may be located on said corner pi.ece in a position to in-terfere with ~`
. -11'75~9~
one or more internal webs ex-tending across the panels at intervals to strengthen same.
At least one of said interference projections may extend laterally from vne of sa;id spigots at OI' adjacent the free end thereof whereby to lncrease the width of the spigo-t and prevent it from being inserted into the end of the associateà
panel in an invertecl position. Such interference projection may be provided at or adjacent the ou-ter end of the spigot only, but preferably extencls alona the full length of the spigot.
An embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings, in which:-Fia. I is a perspective view of a drawer side wallpanel with e~ corner connector adjacent -thereto; and Figs. 2 and 3 are perspective views of a front connector for use in connecting the drawer side wall panel to a clrawer front.
The drawer components shown in the drawings form drawers of so called "knock-down" construction, the sides and back comprising identical extruclecl hollow panels interconnected-at right angles to one another by corner pieces~ The forward ends of the side panels are connected to th~ drawer front by means of front connectors, and inwardly directed slots are provided adjacent the lower edges of the panels to receive the eclges o~ a drawer bot.tom.

.
Referring to Fig. l there :is shown a coçner connector which comprises a~corner post 5 of square shape in plan From which two series of ~hree spigots ~A, 6B, bC and 7A, 7B, 7C project at ~rlght Qn9les to one anothe~. Each spigot is of generally U-form in cross~secti~on ancl the outer surface of the base 8 oF the U carries~an outwardly projectina detent 10. The post comprises upper~and lower portions 5A, SB intercannected by CJ li~nk member~SC of reduced section, the position of the link mem~er coinciding with the posit.ions in the drawer back ancd sides o~ longltudinal re-cesses whlch, in the case of the drawer sides receive. the runners on wh.ich the drawer isrnounted in use.
Fig. 1~also shows a drawel panel IS o-~ extruded plastlcs construction comprising two hollow sections, the larger one 15A of ~hich receives the twc, spigots 7~, 7B carried by the upper portion 5A of the corner pos-t 5 and .i5 divlded interrlal].y by a transverse web 16. The small~er hollow section 15B
receives the third spigot 7C ancl is separated from the larger section hy~a web member 17 defining a longitudlnal rece~ss 18A in the panel which, in the case of the~drawer side pane.Ls, engages wlth~the drawer runner. The~smaller sec~ion 1~5B
also incorporates an inwardly dlrected 10ngit~lclinal recess or slot 18B which receîves and retains an edge. o~ the drawsr bottom (not shQwn). Three holes 1~ are provided adjacent the end of the panel ~5 and receive the detents lO car~ied on the respective spigots to retain the spicJots in posi-tion in the ends of the panels. By depressing these deterlts after assembly ~ 7$ ~ ~ ~
it is possible to separate the eomponen-ts and this is assisted, particularly in the case of the spigots carried on the lower portion of the corner post, by charnfering the outer corners of the side walls of each spigot as shown at 20~
; In order to prevent the corner piece from being fitted t.o the panel in an inverted positiGn, in which event the link member 5C would not be positioned in alignment with the runr1er recesses 18A in the panel, the base 8 of each of the upper spigots 6A and 7A is extended beyond the lower side wall 8A
to form a projecting flange 21 which renders I:he overall width of the spigot greater than that of the cavity 15B in which the lower spi~ot 7C is intended to fit. Thus, if the corner piece is presented to the panel in an inverted cond.ition it cannot be inserted since neither ~t` the upper spigots 6A or 7A (whi.ch are then in the lo~ermost position) will fit .into the lower cavity 15B of the panel. The user must therefore invert the corner piece and, since the spi(3ot 6C will not fit into the : cavity 15B due to interrerence wi.th the sJ.ot 18B, .is thus preven-ted from fitting the corner piece :incorrectly.
It will. be appreciated that in order to uch.;eve its ~unction the pro3ection 21 need only be present at or adjacent the outer end of the spi~30t, but it is preferred For reasons of strength and simplicity in moulding tha-t the projection should extend along the entire len(3th oF the spiaot.
In order to prevent the wrong series oF spigots 6A, 6B, 6C or 7A, 7B, 7C being inserted in the ends of the wall panels when the corner piece is in its correct upright pos.ition~
~ ~..75~9Z
flan~3e-like extensions 23 ure providecl at the upper and central spi~ot ~ernbers of the corner pieces 3. These extensions interfere with the lnternal webs 7 of the wall panels S if the corner piec~s are offered -to the waLl panels in a reversed but not inverted position. Incorrect assembly is also prevented in appropriate cases by interferer1ce bet~Jeen the spigot ~embers and the recesses 1~3 in -the panels.
The side wall panels are connected to the drawer front by front connectina members 4 one of which is shown in Figs.

The side wall panels are connected to the drawer front by front connectina members 4 one of which is shown in Figs.

A raised rim 40A is providec! round the peripheral edge o-f the face plate 40. This provicles a slicJht clearance between the surface of the face plate and the surface o-f the draweI
front to which it is attached so that the face plale contacts the drawer front at all pOil1ts on its per:iphery clespite any slight surface irregulc~ities on the cdrawer fron-t. The .

Various modifica tîons moy be made wi thout departing from the inventionO For example the number and construction of the spigots may vary considerably as may the cavities in -the wall panels into wllich they require to fit. The nature and number of projections requlred to prevent incorrect fitting will therefore vary dependent on the na-ture of the component.
Moreover while in the embocliment described the spigots are retained in the ends of the panel members by means of deten.ts engaging in holes in the panels, -the spi~Jots could be retained in sorrle other manner, fo.r example by means of adhesive.
