Definitions

  • the invention relates to connecting devices for interconnecting components at right angles to one another and is especially, but not exclusively applicable to components for use in construction of articles of furniture including drawers.
  • Drawers constructed in this manner can be packed in relatively flat form since the wall panels, base and facia all consist basically of flat boards.
  • the connecting members which are used to interconnect the wall panels at right angles to one another have spigots or similar projections extending from them in two directions at right angles and cannot therefore be packed flat.
  • a connecting device for interconnecting two components at right angles to one another, the device incorporating projections extending at right angles to one another and adapted to engage with the ends of the components to be interconnected, the respective projections which engage with such components being carried on separate parts of the connecting device, which said separate parts may be interengaged such that the respective projections extend at right angles to one another, and each said separate part of the connecting device being dimensioned such that when engaged with respective components, the said separate part does not project laterally beyond the outer surface of the respective component.
  • the connecting device may be supplied to the customer in separable parts which can be packed flat, the parts being interengaged during assembly of the article such that the projections and the components engaged therewith extend at right angles to one another.
  • one of said separate parts in- dudes a corner piece on which the associated projection is carried, the corner piece being hollow and being adapted to receive a portion of said other separate part, means being provided for engaging the said portion in the corner piece.
  • the connected device may be provided with a single projection for engagement with each of the components to be interconnected or with a plurality of projections for each component. Said portion of the separate part which engages with the hollow corner piece may extend into the corner piece from the side from which the projection or projections will extend after assembly or the separate part which engages with the corner piece may be arranged to pass through the corner piece from the opposite side so that from which the projection will extend after assembly.
  • the separate parts which form the connecting device are interengaged by means of internal projections in the hollow corner piece which co-operates with apertures or recesses in the portion of the other separate part which engages with the corner piece.
  • the projections may be engaged with the components to be interconnected in any suitable manner, for example by means of adhesive.
  • the projections are preferably provided with releasable locking means for engagement with the wall panels.
  • the wall panels are of hollow extruded plastics form the projections may be adapted to engaged within the open ends of the panels, the locking means comprising projecting detents on the projections which engage with apertures adjacent the end of the panel.
  • a corner connector for interconnecting two drawer wall panels at right angles to one another.
  • the connector is intended for use with wall panels of extruded plastics form and is provided with a first projection 5 and a second projection 6, extending at right angles to one another from a corner piece 7.
  • Each of the projections 5, 6 is of generally U-shaped form in cross-section and carries a projecting detent 9 which engages with a complementary hole in the side wall of the associated panel. In this way the panel may be disengaged from the corner connector subsequent to assembly if desired.
  • the corner connector is constructed from two separable parts which are shown in their separated condition in Figs. 1 and 2.
  • the corner piece 7 is hollow and carries the spigot or projection 6.
  • the other spigot or projection 5 is provided with an extension 10 which is adapted to be inserted within the hollow interior of the corner piece 7 to an extent limited by abutment of projections 11 with the upper and lower ends of the corner piece.
  • the extension 10 is provided with apertures 12 which engage with detents 13 (Fig. 1) formed within the hollow body portion of the corner piece 7. In this way the two parts can be locked together to form the assembled corner connector as shown in Figs. 3 and 4.
  • two of the male components incorporating the extensions 10 are inserted in each end of the drawer back as shown in Fig. 5 and retained in position by engagement of the detents 9 with the holes in the panel.
  • the extensions 10 therefore project from each end of the rear wall panel but are disposed in the same general plane as the panel.
  • Two of the female components incorporating the corner pieces 7 are inserted in the rear end of each of the drawer side wall panels and are retained in position by engagement of the detents 9 with the holes in the associated panels.
  • Each corner piece 7 projects beyond the end of the associated side wall panel but is again disposed in the same general plane.
  • the components may therefore be packed flat without any parts projecting at right angles to the general plane of the wall panels to which they are fitted.
  • the extensions 10 When it is desired to assemble the drawer the extensions 10 are pushed into the corner pieces 7 of the associated female components as indicated by the arrows in Fig. 5 and engage with the detents 13 thereby locking the two parts of the connecting device together with the spigots 5, 6 and hence the panels with which they are engaged, extending at right angles to one another. If it is desired to disassemble the drawer the walls can be disengaged from the corner connector by releasing the detents 9 from the complementary holes in the panels.
  • the drawer is completed by a drawer bottom which engages with grooves (not visible in Fig. 5) formed in the inner faces of the side and back wall panels, and a drawer front attached to the forward ends of the side wall panels.
  • the projections 11 form extensions of the upper and lower faces of the corner pieces 7 such that they are of rectangular shape in plan. This results in the side and back wall panels overlapping one another at the inside of the corner which avoids the appearance of unsightly gaps due to variations in manufacturing tolerances.
  • a corner connector for interconnecting two drawer wall panels at right angles to one another.
  • the connector is intended for use with wall panels of extruded plastics form and is provided with a first series of three projections 15 and a second series of three projections 16, the respective series extending at right angles to one another from a corner piece 17.
  • the corner piece 17 is in upper and lower sections separated by a recess 18 which, when the corner connector and panels are assembled, is aligned with a rebate or groove in the side wall panel by means of which the drawer is mounted on a runner, a similar runner being provided at the opposite side.
  • Each of the spigots is of generally U-shaped form in cross-section and carries a projecting detent 19 which engages with a complementary hole in the side wall of the associated panel. In this way the panel may be disengaged from the corner connector subsequent to assembly if desired.
  • the corner connector is constructed from two separable parts which are shown in their separated condition in Figs. 7 and 8.
  • the corner piece 17 is hollow and carries the series of spigots 16.
  • the other series of spigots 15 are carried by a face plate 20 which is also provided on its opposite side with projecting lugs 21 adapted to engage within the hollow interior of the corner piece 17.
  • the lugs 21 are provided with apertures 22 which engage with detents 23 (Fig. 8) formed within the hollow body portion of the corner piece 17. In this way the two parts can be locked together to form the assembled corner connector as shown in Fig. 6.
  • the face plate 20 is provided with a cutout 24 for alignment with the recess 18 in the corner piece 17 to accommodate the drawer runner.
  • a similar cutout is provided adjacent the other end of the plate 20 and serves a similar purpose when the component is reversed as is necessary when forming the other corner of the drawer.
  • Left and right hand versions of the female component incorporating the corner piece 17 are required.
  • one of the male components incorporating the lugs 21 is inserted in each end of the drawer back and retained in position by engagement of the detents 19 with the holes in the panel.
  • the lugs 21 therefore project from each end of the rear wall panel but are disposed in the same general plane as the panel.
  • One of the female components incorporating the corner piece 17 is inserted in the rear end of each of the drawer side wall panels and is retained in position by engagement of the detents 19 with the holes in the associated panels.
  • the corner piece 17 projects beyond the end of the associated side wall panel but is again disposed in the same general plane.
  • the components may therefore be packed flat without any parts projecting at right angles to the general plane of the wall panels to which they are fitted.
  • lugs 21 When it is desired to assemble the drawer the lugs 21 are pushed into the corner pieces 17 of the associated female components and engage with the detents 23 thereby locking the two parts of the connecting member together with the series of spigots 15, 16 and hence the panels with which they are engaged, extending at right angles to one another. If it is desired to disassemble the drawer the walls can be disengaged from the corner connector by releasing the detents 19 from the complementary holes in the panels. It will be noted that a slot 25 is formed adjacent the lower end of the corner piece 17 and a complementary slot 26 adjacent the lower end of the face plate 20. These slots serve to accommodate the corner of the drawer bottom which engages with grooves formed in the inner faces of the side and back wall panels.
  • Fig. 9 shows an assembled corner connector and is generally similar to that shown in Fig. 6. In this case however the manner of interconnecting the two parts differs from that of the arrangement shown in Figs. 6 to 8.
  • the female components incorporates a corner piece 37 which is in the form of a collar or sleeve which is open at opposite ends so that the male component may be inserted completely through the female component from one end.
  • the female component incorporates one set of spigots 36 carrying detents 39 in the manner of the equivalent component in the embodiment shown in Figs. 6 to 8.
  • the other set of spigots 35 are carried on back plates 40A and 40B and are of such a length that the spigots may be inserted completely through the corner piece 37 to project at the opposite side by the desired final distance.
  • the two upper spigots are carried by the plate 40A and the lower spigot by a separate plate 40B.
  • the female components are engaged in the rear ends of the side panels of the drawer and the male components are supplied in loose form.
  • the male components are inserted through the hollow corner pieces 37 of the female components and into the open ends of the drawer back until the detents 39 engage with the complementary apertures in the back panel.
  • the series of spigots 35, 36 and the panels with which they engage therefore extend at right angles to one another. If it is desired to dismantle the drawer the panels can be released from the corner connectors by disengaging the detents 39 from the associated apertures in the wall panels.
  • the embodiments described enable a drawer construction consisting of wall panels interconnected at right angles to be packed in a substantially flat form without parts of the corner connectors projecting out of the general plane of the associated components. This enables savings in space to be effected and reduces the likelihood of damage due to breakage of projecting parts. After unpacking the components can be quickly and easily erected to form a drawer construction while still preserving the facility for dismantling the drawer if required.
  • any desired number, size and arrangement of spigots may be provided for engagement with the respective wall panels.
  • Other means of releasably interconrecting the spigots and the associated wall panels may also be utilised and if dismantling is not required a more permanent form of connection, such as by use of adhesive, may be adopted.
  • the components described are particularly suitable for use in constructing drawers having hollow extruded wall panels but the invention may also be applied to drawers having walls formed from moulded or solid panels and to connectors for interconnecting a wide variety of components other than drawer panels.
