Plastic drawer

The sample relates to a plastic drawer with a upper, preferably laterally outwardly protruding edge and rails for drawer guides are formed.

Such plastic drawers are intended for different drawer guides be suitable, as these are often left to the choice of the buyer for reasons of cost. The following 4 construction principles of drawer runners are currently common:

a) a simple sliding guide that is built for a thin and completely straight continuous running rail on the drawer,

b) a simple roller guide, with which a 4/5 pull-out is possible,

c) a telescopic roller guide that allows full extension when on Drawer, however, a rear stop limiting the pull-out movement must be present, which is usually in the form of a curved bend of the the rear end of the running rail of the drawer is formed,

α, cine on the side wall of the drawer by means of noses, retaining claws , DJoaln, screws or the like. Telescopic Stanlkulissen-, Nojcifuhrung to be attached, with which an over-extension is possible, but which because of their easy running also as 4/5 or full extension and is increasingly preferred by customers.

It is known in plastic drawers, which are probably optionally available for the three first-class Guides a), b) and c) can be used, but not at the same time door hurry guide d), since this has a lot of space in height next to the long side wall claimed. The frequency of use is approximately as follows: guidance a) around 15%, guidance b) around 70%, guidance c) around 15%. The load possibilities should be something like this: Leadership a) about 10 kg, guide b) 10 - 15 kg, guide c) about 40 kg and guide d) about 40 kg.

As for the sliding guide according to a) a completely straight running rail throughout is required, but a running rail for the telescopic roller guide according to c) with the rear end bent as a pull-out flange, known plastic drawers provided for optional use of the guide a), b) and c) have each long side wall two superimposed molded running rails, of which z. B. the one in the upper area of the longitudinal side wall and as Running rail for the guides a) and b) is used, while the other is arranged in the lower region of the longitudinal side wall near the plane of the floor and serves as a running rail for the telescopic roller guide c). As a consequence, that at the height of the space for arranging a telescopic steel link ball guide according to d) is not sufficient. A further disadvantage is that when using the upper running rail, that is to say the guides a) and b), the longitudinal side walls of the plastic drawer be pressed inwards when loading. One therefore has an additional rib support for the upper running rail in a known embodiment intended. This requires a number of thin mold pins on the injection mold, which are difficult to cool. The lower runner for the one

You have already been given an implementation option in which to reduce the Herstei! I, nrscw. ^: wc. "X3s cm bottom of the plastic drawer a metal rail a; a Lcwfschiene befosrj ^ t if a telescopic roller guide according to c) is desired. In addition, cn the upper edge of the longitudinal side walls is a running rail for the guides according to c) and b) integrally formed, i.e. in a zone of low stability, so that in about 30 to 35 % of applications there is a risk that the longitudinal side turn will be pressed inwards when the load is applied and the drawer slide will not work properly as a result To omit the upper molded plastic running rail and to provide de unrere metal rail for all types of guidance would not be affordable for reasons of cost.

In this situation, the pattern is based on the task of creating a plastic Schw -.- ccsten of the type mentioned above, which can be used for all 4 types of management _. to d) can be used and has a high stability with regard to the agitation structure, with the least possible ribbing and a correspondingly simple injection mold with as little bad as possible

E per se known MetalIsd'iene is set, the self in a load-bearing manner with the side wall and / or the floor of the plastic drawer is connected. The MetaKichiene is expediently placed under the plastic Lcufschie.ο and is supported preferably from this.

In a preferred embodiment, the metal rail has, in a manner known per se, a double and opposite angular shape, with the upper leg under the plastic running rail, the middle section on the long side wall and the lower leg under the bottom of the drawer attached. If the plastic running rail in the pattern according to the metal! Rail

additionally supports, know it ccnüceri when the metal rail; cn the Plastic drawer is only fixed to the fixed part. A friend Stop for the pull-out cb &wcgurc; egg ":". · ^ skc. ^ - pipe routing is preferred arranged on the metal rail. The cn ^ .-- fr—. right plastic guardrail go * straight through.

The rnusiercjernc.ie solution is: ir. Jecerr. io: eir.car.gs mentioned problematic points in handing over white berried-rand. It is: possible to use 4 guides in a hurry. The Metciischler.e is only used when the telescopic roller guide according to c) is desired. The drawer is correspondingly cheaper than the other operators. By arranging the single angeiormten plastic running rail in the lower area, in the vicinity of the plane of the Schubkcsrenbodens results in a high Stcbiiirct so cc3 these plastic running rail provided for their only up etv / c 15 kg Belcstung rührur.gscrren a) and b) does without ribs. This results in a correspondingly lower material production cost, a simpler production form with significantly fewer mold pins that are difficult to cool, and a correspondingly shorter production time. By eliminating a Stützverrippung for the plastic running track is saved in the widthwise space or the longitudinal side Wend of Schubkcsiens and the engaging guide need together in the width less space, so dc3 the inust ^ rgemäße drawer can be built for the same clear outer Elnbcumcj jreiter as the well-known embodiment described at the outset.

Compared to the earlier embodiment described in the second place the advantage that not only is there a much larger C. ^ Üitat available, but also the upper section of the Lür.jjjoircnwcr.de is available a strong upper, laterally towards the cusclet. the edge, z. 3. in the form of a Double bar with intermediate ribbing, trainee on, through which the

7033693 io.iz70

Drawer along the upper edge <- 'i {is stiffened, namely a such a double skirting board still have a certain height, without the pretty high telescopic steel backdrop spherical guide to take up the necessary space. In the sense of the aforementioned earlier execution arrest one such thing <-> dismiss beren It would not be possible to use the edge as a running rail, as the well-known handicrafts are common Guides according to a) and b) are built for a thin running rail.

In addition, it is essential that the plastic running rail arranged according to the pattern, when using a telescopic roller guide according to c), supports the load of up to 40 kg, so that the metal rail can be made correspondingly weaker or its door connection with the drawer can be correspondingly easier , e.g. B. only in the form of a clamp or snap connection. Even if z. B. by means of a screw connection or the like. Such a firm support connection of the metal rail with the drawer is provided that the plastic running rail does not initially carry it, but there is the advantage that it is available as a backup in the event that the support vp 'breaks. hindered as a result of overloading the drawer. The drawer then does not break down right away, but first rests on the plastic running rail.

Further details and advantages of the pattern emerge from the following Description of an exemplary embodiment shown schematically in the drawing, In the drawing each show in a partial cross section through the Lüngsseitenwand a plastic drawer

Fig. 1 shows a known embodiment with the 3 types of guides a), b) and c) and Fig. 2 shows an embodiment according to the model with the 4 types of guidance a) to d).

From the known drawer according to FIG. I and the drawer according to the model According to Fig. 2, a longitudinal side wall 1 and the bottom 2 are seen in the drawing-

lich. The yon ze drawer body is molded in one piece from plastic. Is in the upper-'i area aer Lcngsseiter.wcnd 1 a seirlich outwardly cbstehencier Rar .. ^ ij ebÜdet. This consists of a cngeformien double bar 4, 5 with de v. , .ιliegender VsrrippuT.g 6th Dcr.eber. is, as the drawing shows * ', - a line of notches 7 formed.

In the well-known embodiment, fig. 1, a piece far below the protruding edge 3, a piece of Lc; jfichiene 8 is formed in the upper area, which is for the sliding guide a) and the simple roller guide b) In order to increase the stability in this upper area of the longitudinal side wall 1, the running rail 8, as the drawing shows, is about half of its width by a verri / ^ ung 9 upwards abc, .- i: ützi For the telescopic roller guide c) a second running rail 10 is formed in the lower area of the longitudinal side wall 1, which consists of a double bar 11, 12 with ribs 13 in between. Between the running rails 8 and 10 there is also a narrow rib 14 thus there are four ribs 6, 9, 13 and 14. The production mold is correspondingly complicated with numerous mold pins that are difficult to cool.

In the exemplary embodiment according to FIG. 2, 1 is on the longitudinal side wall a single running rail 15 in the lower area, near the level of the drawer bottom 2 molded. It consists of a simple bar, similar to the running rail 8 in Fig. 1, but is due to the arrangement in the lower area, in Additional ribbing is not necessary near the bottom of the drawer to increase stability. The running rail 15 is arranged approximately where the lower bar 12 of the running rail 10 of the known type according to Fig.l is. she serves as a running rail for the sliding guide a) and for the simple roller guide b). The fact that, compared to the known design according to FIG. 1, the

7033693 10.1170

drew running rail 8 with the ribbing 9 and the bar 11 and the Ribs 13 are omitted, there is a height distance H to the underside of the Laterally outwardly protruding edge 3 is available for recording both over the top of the running rail 15 Hegenden respective parts of the sliding guide according to a) or the simple roller guide according to bj or the telescopic roller guide according to c) as well as the ar of the longitudinal side wall 1 by means of not shown in detail Noses, retaining claws, dowels, screws ο. Like. Telescopic Starkuiisser · -Kuge! guide to be attached according to d) is sufficient. The narrow ribbing 14 is maintained and extends along the entire height distance Jj_.

Using the telescopic roller guide according to c), a metal rail 16 is placed under the molded plastic running rail 15 with direct contact on this, which in the exemplary embodiment has a J-shape that is angled twice and in opposite directions, the upper Se ' . * ¹ .!;?! 7 under the running rail 15, the middle section 18 rests against the side wall 1 and the lower leg 19 under the floor 2 or a Verrippong (not shown) attached there. This Mercllschiene 16 is kept relatively thin due to the supporting function of the plastic running rail 15 and clamped in a manner not shown in the cavities formed by the ribs running under the bottom 2, not shown. At the end of the metal rail 16, a stop for c "ϊ extension movement of the telescopic roller guide is arranged in a known manner, not shown.

As can be seen from the comparison of FIGS. 1 and 2, the pattern is in accordance with the pattern Plastic drawer is much simpler and still has the for functional advantages of more secure stability and the possibility of arrangement the guidance according to d). It can also be seen that the necessary width B «for the L.-ngsseitewand 1 and the built-in guide in the multi-purpose drawer according to Fig. 2 is less than the width B. in the known solution of Fig. 1.-

7033693 io.i2.7O

There are still certain possibilities for modification within the framework of the Mustor-compliant teaching. The upper edge 3 does not necessarily have to be opposite the longitudinal side wall 1 stick out sideways. Furthermore, a metal rail according to the pattern can also be placed over the Plastic running rail 15 can be arranged. In terms of wear and tear through however, the most heavily loaded lower support rollers and the simpler connection of the metal rail with the drawer is the version shown more advantageous.
