Definitions

  • the invention relates to a drawer with metallic drawer frames as side boundaries of the drawer, which are preferably provided at the top with guide rails forming part of a pull-out guide and at the bottom have an angled support flange for supporting a base plate of the drawer, holding flaps being punched out and bent out of the support flange for the engagement in a groove provided in the overlap area of the base plate and the support flange is provided in the base plate and engage with the material of the base plate with at least one claw-like attachment from the groove flank.
  • Such a drawer is known from AT-PS 388 651 and DE-0S 38 05 669.
  • the drawer frame is given a multiple function by the preferred attachment of the guide rail and by the supporting flange with the holding tabs, whereby no other fastening means are necessary for the attachment of the base plate, the base plate because of the attachment of the grooves only with regard to the edge spacing of these grooves and not, as in the case of individual recesses to accommodate holding means must also be adjusted with regard to the longitudinal division to the attachment location of the holding tabs and can simply be cut to length from running plate material of appropriate width and finally an engagement of holding elements of the holding tabs in the groove flank is possible at a distance from the groove opening edge, the material of the base plate between the area of engagement of the holding elements and the Nutrand remains undamaged and therefore fully sustainable.
  • a disadvantage of the known design is an elaborate shape of the retaining tabs and also an elaborate type of attachment.
  • these retaining tabs are punched free from the free flange edge according to cutting lines running transversely to the flange longitudinal direction, tapered in the area of the free end and bent into a claw.
  • the retaining tabs are bent up so far that the inner edge of the bending point forms a support for the edge of the frame on the frame side and the retaining tab with the claw can be inserted into the groove of the attached base plate.
  • a pliers-like tool or a spreading tool with counter-support on the frame is used to re-bend the retaining tab into a position parallel to the groove flank, possibly resting on the groove flank, the claw being pressed into the material of the groove flank.
  • This bending process is difficult to automate. During the re-bending it can damage the flaps and especially if the frames z. B. for rust protection with a surface coating, such as a powder coating, damage to this surface coating and thus come to undesirable rust spots during use. It is also not possible to stack the frames for shipping in such formed retaining tabs, so that there is a large space requirement for shipping. It is also necessary to adhere to very narrow manufacturing tolerances for the edge spacing of the grooves.
  • the holding tabs and claws prevent longitudinal and transverse displacements of the base plate with respect to the side frames and also a lifting of the base plate from the supporting flanges of the side frames.
  • Other known constructions only partially meet these conditions, in particular separate ones Holding means must be provided to prevent the base plate from lifting off the flanges or this possible lifting is even accepted. It is known, for example, from EP-A-0 322 545 to bend holding flaps upwards according to bending edges running at an acute angle to the flange longitudinal direction, so that the flaps are aligned obliquely to the groove and cut into the groove flanks with their longitudinal edge edges when the base plate is pressed on.
  • assembly is possible simply by pressing on, but the edges of the retaining tabs cut straight grooves into the groove flanks, so that open insertion beads are created towards the edge of the groove and lifting of the base plate from the flanges is possible, at least in the course of using a corresponding drawer.
  • the object of the invention is to provide a drawer of the type mentioned, in which, while maintaining the basic advantages, simple fastening and using simple tools enables the base plate to be securely fastened to the frame.
  • the retaining tabs are punched free in the longitudinal direction of the flange, bent transversely to the longitudinal direction of the flange and the groove, and at a distance from a foot part at the bending point are provided with lateral projections which form claw-like projections and which press into at least one groove flank when the base plate is put on , wherein the bottom plate in a position offset in the longitudinal direction with its groove can be placed on the tabs and after being placed in the longitudinal direction of the flap is displaceable into its end position, so that the press-in traces generated by the projections in the groove flank produce one during placement, from the groove into the inside of the groove and show a subsequent leg running approximately parallel to the groove edge.
  • the retaining tabs can in the end position on the support flange, whereby there is no risk of damage to any surface coating when mounting the base plate.
  • the assembly is carried out by a simple installation process, which is followed by an equally simple displacement process, which is why automation of the assembly is possible.
  • the press-in tracks generated are at an angle to one another, there is no danger that the base plate will lift off the flange.
  • the arrangement can be such that the base plate is secured against displacement in the end position, for example by a front plate or rear wall of the drawer. In normal cases, however, the claws are clamped in the press-in tracks for proper attachment.
  • the special shape of the claw-like attachments can depend on the respective circumstances and above all on the production material of the frames and the thickness of this material.
  • larger and, in the case of more difficultly deformable material smaller claw-like approaches can be used which, in the case of more easily deformable material, can even bend somewhat at least during the displacement of the base plate with respect to the flange and then form barb-like counterholders.
  • Arrowhead or sawtooth shapes are particularly suitable for the design of the claw-like approaches.
  • One or more claw-like approaches can also be provided one above the other for each groove flank.
  • a further embodiment is characterized in that the lobes have a width which is equal to or less than the groove width over the greater part of their length and are provided at the ends with opposite projections intended for engagement in the groove flanks. It is mainly these claw-like projections in this embodiment generate the press marks in the groove flanks.
  • the projections with oblique flanks merge into the adjoining flap bodies, these oblique flanks also generating corresponding oblique flanks in the press-in tracks and forming wedge surfaces interacting therewith, so that the pressing of the upper side of the flange onto the underside of the plate is ensured.
  • a particularly secure fit of the base plate on the frame is ensured if, according to a further development, the distance of the long side of the flaps facing the frame from the frame is kept equal to the desired distance of the outer groove flank from the edge of the base plate, the foot part on this side having an arcuate shape the groove pressing into the transition flange passes over.
  • One of the groove edges is slightly deformed here, which further improves the tensioning of the claw-like attachments in relation to the flange.
  • a drawer has two opposite side frames 1 and a base plate 2 made of wood-based material.
  • the drawer frames 1 serve as a side boundary or side walls of the drawer. Front and end plates and a drawer slide were not shown.
  • the drawer frame can have a molded guide rail on top and it can on the frame 1 also rollers of a corresponding pull-out guide can be stored.
  • an angled support flange 3 is formed with a transition piece forming an exemption 4.
  • Holding flaps 5 are punched out essentially in the longitudinal direction of the flange at two or more points spaced apart from one another and bent approximately perpendicularly to this longitudinal direction of the flange.
  • the holding tabs as can be seen in FIG. 1, have the same or a slightly smaller width in their central region than a groove 6 provided in the bottom plate 2 parallel to the edge 6.
  • claw-like projections 7 are provided, which are for engagement in the Groove flanks 8, 9 are determined and which merge with oblique flanks 10 into the subsequent flap body.
  • the distance of the long side of the flaps 5 facing the frame 1 from the frame is in the central region and in relation to the inner side of the frame 1 above the clearance 4 is equal to the desired distance of the outer groove flank 9 from the bottom plate edge 11.
  • the base part of the flaps 5 containing the bending point 12 goes from the central region in the arcuate transition 13 into the flange 3.
  • the frame 1 with the flange 3 is placed on a holding tool 14 which has support spikes or holding heads 16 which engage in the openings 15 formed by the bending of the tabs 5 and which can also be extended into the groove 6 and then the tab 5 support within the groove.
  • the base plate 2 is placed in a position offset with respect to the end position, so that the projections 7 in the groove flanks 9 and 10 initially produce press-in traces which run inwards from the outer groove edge and are located under the flap 5 in FIG. 2.
  • the frame 1 is displaced relative to the plate 2 in the direction of arrow 17, so that press-in tracks 18 running parallel to the groove edges are created.
  • Fig. 2 there was a shift the frame 1 shown relative to the plate 2 to the right.
