Description
This invention relates to drawers for desks, tables or the like and to a method of making such drawers.
Desk drawers, for example, are often of relatively complex construction and are difficult to assemble. A
modern desk drawer may be made mainly of sheet metal parts bolted or welded together and fitted with a wooden front. Although the metal parts themselves can be manufactured rapidly by machine on a mass production basis, the time required to assemble the parts is relatively high, which makes for a high labour cost factor. Similar problems apply with other t~pes of conventional drawers.
An object of the present invention is to provide a drawer which can be assembled substantially more quickly and easily than conventional drawers. A further object is to provide a method of making such a drawer.
The back and sides of the drawer according to the invention are formed from a single extruded panel bent transversely along tw~ lines spaced longitudinally of the panel so as to define two side sections and a back section arranged at appropriate mutual angular orientations. The front of the drawer is secured to the outer ends of the side sections. Each said section is formed along its lower margin with an inwardly-directed channel receiving the -side and rear marginal portions of the bottom of the drawer.
Each side section is also formed with at least one out- -wardly directed rib extending parallel to said channel in ., the section and defining a runner for use in slidably locating the drawer in use.
The invention also provides a method of making a drawer. The first step is to form a single extruded panel of a length equal to the sum of the lengths of the back and sides of the drawer to be made and of a width equal to the required height of the said back and sides.
Along one longitudinal margin, the panel has a continuous i channel facing to one side of the panel. At least one ~
continuous rib extends parallel to said channel at the opposite - side of the panel to define a runner for slidably locating the drawer in use. The said rib and the back ~f the channel ', are cut through at said opposite side of the panel along ' ; 10 two rectilinear parallel lines disposed normal to the longitudinal edges of the panel so as to divide the panel into three sections disposed end to end and intended to ~;, form respectively one side, the back, and the outer side of the drawer. The side sections of the panel are then bent inwardly about said lines to positions in which the side sections are disposed at the required angular orientations with respect to the said back section with the portions of the said channel on the side sections -facing one another. A bottom panel is then engaged in -' 20 the portions of the said channel on the side and back section and finally a front panel is secured to the outer ~-~ ends of the side sections.
Preferred embodiments of the invention will now be described with reference to the accompanying drawings in which:-Fig. 1 is a perspective view from one end of partof an extruded panel used in making a drawer according to the invention;
Fig. 2 is a perspective view from one side and - 30 above of the complete panel, and indicates how the panel is to be bent to form the sides and back of the drawer;

Fig. 3 is an exploded perspective view of the drawer, showing how the extruded panel is fitted with a bottom panel and a front panel.
Fig. 4 is a detailed view of part of Fig. 3 and illustrates how the front panel is secured to the extruded panel;
- Fig. 5 is a view similar to Fig. 4 and illustrates an alternative method of securing the front panel to the ~'~ extruded panel; and, Fig. 6 is a detail view of one end of the front :
f, panel and illustrates an alternative method of securing -~ the bottom panel of the drawer to the front panel.
Reference will first be made to Fig. 1 which shows one end of an extruded aluminum panel 20 used to form the sides and back of a drawer. Fig. 2 shows the complete i panel at a subsequent step in the sequence of operations involved in making a drawer. As can be seen from Fig. 2, 'I
the panel 20 is of relatively narrow elongate form. The length of the panel is substantially equal to the sum of ~ 20 the required lengths of the sides and back of the drawer. -,` The width of the panel is equal to the required height ~- of the said sides and back.
- Referring back to ~ig. 1, the panel 20 includes a back wall 22 formed along one longitudinal margin with a - channel generally designated 24 which faces to one side of the panel 20. An angle-section formation 26 extends along the opposite longitudinal margin of wall 22 at the opposite side of the panel. A pair of continuous parallel ribs 28 extena along the panel intermediate the channel 24 - 30 and the formation 26 at the same side of the back wall 22 as the formation 26. As will be described, when the panel is in use, it is positioned so that the ribs 28 are external to the drawer and the channel 24 faces ~nwardly. In the assembled drawer, the ribs 28 serve as runners for slidably locating the drawer in a desk or the like in use. The channel 24 is of generally square shape and defines a slot 30 of a width to receive a bottom panel of the drawer. Formation 26 includes a wall portion 32 which, when the drawer is assembled, forms the visible upper edge of the sides and back of the drawer. This gives the sides of the drawer an appearance of greater width than would be the case in the , .
absence of the formation. The ribs 28 are provided for ~ the purpose of slidably locating the drawer in a desk, ¦ table or the like in use.
:
Assuming the panel 20 has been cut to the required ~- length, the next step is to cut through the ribs 28 and ~- the base 31 of the channel 24 down to the level of the back wall 22, along two rectilinear parallel lines 34, 36.
These lines are disposed normal to the longitudinal edges of the panel at distances from the respective ends of the panel equal to the required lengths of the respective . ( sides of the drawer. In other words, the lines 34, 36 ~,~ in effect divide the panel into three sections 38, 40 and 42 which are disposed end to end and which will respectively form one side, the back and the other side ., .
of the drawer. In addition to the cuts, a small portion is cut off each end of the channel 24, each of the ribs 28, and the formation 26 so as to leave plain portions ~: .
44 of the wall 22 exposed at each end of the panel.
'~ Each of the portions 44 is formed with two rectan-,~- gular tabs 46 which are bent upwardly at right angles to the back wall 22 of the panel in Fig. 2. Before bending, r~,'.. ~ each tab is formed with a transverse slot 48 to receive a screw for securing the panel to a front panel of the drawer as will ,,~ .: .
. .
.
"
be described. Portions 22a of the back wall 22 remain after the slotted tabs 46 have been bent up (see Fig. 3).
~` The rib 28 nearest the formation 26 includes, in each section 38, 42 of the panel, two small rectangular ; tabs 49a, 49b. Each tab 49a, 49b is formed by cutting ! through the rib and then bending towards the formation ~- 26 a portion of the rib adjacent the cut. The purpose ' of these tabs will be described later.
The side sections 38 and 42 of the panel are now bent downwardly in the directions of the arrows in Fig. 2 to the ghost outline positions 38' and 42' respectively.
; ; In these positions, the side sections 38 and 42 are disposed -~ at right angles to the back section 40. The cuts along lines 34 and 36 through the channel 24, the ribs 28 and , the formation 26 ensure accurately-positioned and well-defined bends. Further, the channel, ribs and formation 1 1 stiffen the sections of the panel and prevent them bending ~ other than at the correct locations.
::,, ~ Fig. 3 shows the panel 20 in its bent configura-~. .
~-~ 20 tion ready to be fitted with a bottom panel 50 and a front ~' panel 52. The bottom panel 50 is engaged with the panel 20 by engaging the side margins of the bottom panel in the ,:
s ~ portions of the slot 30 of channel 24 along the lower margins of the side sections 38 and 42 and sliding the panel along the : .
i slot portions. When the bottom panel is in its fully engaged ~ position, the rear end margin thereof engages in the portion .,. :. , of slot 30 along the lower edge of the back section 40 of - panel 20. Finally, the front panel 52 is fitted to the outer - ends of the side sections 38 and 42 of the panel 20. The front ; 30 panel 52 is made of wood and is formed with a horizontal groove 53 to receive the front margin of panel 50 and with two parallel vertical grooves 54 at positions to receive the :i - plain end portions 44 of the wall 22 of panel 20.

Finally, the front panel 52 is secured to the panel 20 by screws 56 (Fig. 4) passing through the slots 48 in the tabs 46 in the plain end portions 44 of panel 20 and screwed into the rear face of the front panel 52. The provision of slots in the tabs 46 as opposed to holes has the advantage of allowing adjustment of the positions of the screws.
Referring back to Fig. 3, the tabs 49a, 49b referred to above project upwardly from the rib 28 which is uppermost in the assembled drawer. The tabs 49a nearest the front of the drawer are provided for co-operation with a lock mechanism in the desk or the like in which the drawer is used. Tabs 49a are provided at both sides of the drawer so that the drawer can be used as a right hand or left hand drawer, although the lock mechanism will co-operate with one of the tabs only.
The rearmost tabs 49b serve as drawer stops for co-operation with latch members in the desk or other article of furniture in which the finished drawer is used. In Fig. 3, one of these latch members is indicated in chain lines at 58. A similar member will be provided for co-operation with the tab 496 at the other side of the drawer, although this tab is not visible in Fig. 3. When the drawer is inserted into the desk or the like, the tabs 49b deflect the latch members 58 and the latch members fall down behind the tabs, which act as stops preventing the drawer being completely withdrawn from the desk or the like.
Fig. 5 shows an alternative method of securing the front panel 52 to each of the side sections 38 and 42 of panel 20.
Primed reference numerals have been used in Fig. 5 to denote ... .. .
parts corresponding to parts of the previous figures. In the - Fig. S embodiment, the end portions 44' of the side sections of the panel 20' are plain li~e-~ the folded tabs 36 of the previous -~ embodiment are omitted), and the portions are formed with pre-punched holes 60 to receive staples 62 driven into the ends of the front panel 52' and positioned so as to penetrate - the holes 60. Accurate positioning of the staples can be :, : - 7 -' .'~' , . .
~3~
~ffected using a simple jig to position the front panel with respect to a staple gun. Pre-drilled holes such ; as those indicated at 64 may be provided in the front panel to receive the staples.
Fig. 6 illustrates an alternative method of securing !
; the bottom panel of the drawer to the front panel. Double primed reference numerals have been used in Fig. 6 to i~ denote parts which correspond with previous figures. In this embodiment, the front panel 52" has no transverse ~'~ 10 slot to receive the front edge of the bottom panel 50".
Further, panel 50" is dimensioned such that its front edge abuts the rear face of the panel when the drawer is assembled. In this case, the front marginal portion of the bottom panel 50" is supported on a fillet 66 which ~` is secured to the rear face of the front panel 52" and ~` to the bottom panel 50". The fillet 66 is secured to the i panels by adhesive. One or more staples may additionally be driven through the fillet into the front panel. This method of securing the bottom panel 50" to the front panel , 52" has the advantage that it allows adjustment of the position of the front panel during final assembly.
~ , .
It is finally to be noted that the preceding description refers to specific embodiments of the invention only and that many modifications are possible ~: ~
within the broad scope of the invention. For example, .
~; the materials used for the various parts of the drawer - may vary. In the example described, the panel 20 is made of aluminum, although other suitable soft metals ~4!,,,, may be used in other cases. Further, materials other ~,.
~; 30 than wood may be usea for the bottom panel 50 and the ; front panel 52.
,., Within the braad scope of the invention, it is not essential to form cuts in the extruded panel ~` to facilitate bending thereof. In some situtions, it may be more convenient to bend the panel using available bending equipment.
i~i `~' Methods other than those specifically described ?~i may be used for attaching the front panel 52 to the side section~ of the panel 20. For example, a suitable adhesive could be employed. Also, it is, of course, to be understood that the dimensions of the panel 20 may vary. In the case of, say, a deep drawer intended to contain files, panel 20 might be of ten inches in width. At the other extreme, a shallow drawer might require a panel of only two inches in width.
Apart from the question of width, the length of the ~- various sections will, of course, vary, depending on ~ 1- the size of drawer required.
7i-~
. .
The shapes of the channel, the formation 26 and the ribs 28 can also vary. For example, in another 20 embodiment, it may be desirable to provide a rounded ;i ,.
i; upper edge on the side sections of the drawer, in which case formation 26 will be of rounded configuration.

A drawer as claimed in Claim 2, wherein the end portions of the channel, the rib and the said angled formation are cut away at opposite ends of the panel, leaving plain end wall portions on the panel, and wherein the front of the drawer is formed on its inner face with slots receiving said plain end wall portions, said portions being retained in the slots to secure the front to the said panel.
5. A drawer as claimed in Claim 4, wherein each of said plain end wall portions is retained in the associated slot by a plurality of tabs cut into said portion and bent laterally with respect to the panel, each tab being secured to the inner face of the front of the drawer by a screw passing through said tab and screwed into the front.
6. A drawer as claimed in Claim 4, wherein each of said plain end wall portions is retained in the associated slot in the front by a plurality of staples driven into the adjacent end of the front of the drawer and through pre-punched holes in said plain end wall portion.
7. A drawer as claimed in Claim 2, wherein the said panel is in the form of an aluminum extrusion having a pair of parallel ribs on the same side of the panel as said angled formation.
8. A drawer as claimed in Claim 7, wherein the rib which is uppermost in the assembled drawer is formed with upstanding tabs at respectively opposite sides of the drawer, which tabs serve as drawer stops when the drawer is in use.
9. A method of making a drawer having a front, a back, two opposite sides and a bottom, the method comprising the steps of:
forming a single extruded panel of a length equal to the sum of the required lengths of the said back and sides of the drawer and of a width equal to the required height of said back and sides, the panel being formed along one longitudinal margin with a continuous channel which faces to one side of said panel and which is of a width to receive the bottom of the drawer, and the panel being formed at its side opposite to said one side with at least one continuous rib extending parallel to said channel to define a runner for slidably locating the completed drawer in use;
bending the panel along two rectilinear parallel lines disposed normal to the longitudinal edges of the panel so as to define three sections disposed end to end intended to form respectively one side, the back and the other side of the drawer, said side sections being inwardly displaced to positions in which they are disposed at the required angular orientations with respect to the said back section, with the portions of said channel on said side sections facing one another;
engaging a bottom panel in the portions of said channel on said side and back sections; and, securing a front panel to the outer ends of said side sections.
forming a single extruded panel of a length equal to the sum of the required lengths of the said back and sides of the drawer and of a width equal to the required height of said back and sides, the panel being formed along one longitudinal margin with a continuous channel which faces to one side of said panel and which is of a width to receive the bottom of the drawer, and the panel being formed at its side opposite to said one side with at least one continuous rib extending parallel to said channel to define a runner for slidably locating the completed drawer in use;

engaging a bottom panel in the portions of said channel on said side and back sections; and, securing a front panel to the outer ends of said side sections.
10. A method as claimed in Claim 9 further comprising, before said step of bending the panel, the additional step of:
cutting through the said rib and the channel at said opposite side of the panel along said rectilinear parallel lines.
cutting through the said rib and the channel at said opposite side of the panel along said rectilinear parallel lines.
11. A method 15 claimed in Claim 9, wherein said step of securing a front panel to the outer ends of the side sections is effected by cutting away the end portions of the said channel and the rib at opposite ends of the panel to leave plain end wall portions on the panel, forming on the inner face of said front panel, parallel slots to receive said plain end wall portions of the panel, and retaining said portions in the slots to secure the front panel to the outer ends of the side sections.
12. A method as claimed in Claim 10, wherein the said plain end wall portions of the panel are retained in the slots in the front panel by forming laterally deflected tabs along each of said plain end wall portions, and securing said tabs to the inner face of the front panel by screws.
13. A method as claimed in Claim 10, wherein each of said plain end wall portions of the panel is retained in the front panel by driving staples into the adjacent end of the front of-the drawer and through pre-punched holes in said wall portions.
