Description

The invention relates to a guide support for a

  extractable wire basket placed in a cabinet.

  As in practice, the cabinets intended to take up extractable wire baskets vary in width within a certain range, for example up to 10 mm, the guide rails of the wire baskets must be adjusted in width on the wire baskets, and Intermediate parts must therefore be installed between the walls of the cabinet and the guides when fixing.

  which has unfavorable effects on the assembly.

  The object of the invention is to provide a guide support for wire basket, which is simple to assemble, inexpensive to manufacture and easy to handle, and allows suitable continuous adjustment. and progressive to the different widths of cabinets, and thus does not require any particular prior measure to

wire basket extraction.

  This object is according to the invention achieved in that, on the two longitudinal sides of the wire basket is disposed an adjustment rail, and in that the two adjustment rails each hang with adjustable spacing the longitudinal end of the bar transverse carrier front and rear of the wire basket, for adjustment to

different cabinet widths.

  According to another characteristic of the invention, each adjustment rail has at each of its longitudinal ends a hollow head and projecting in the direction of the wire basket, head in which is inserted a longitudinal end of a transverse bar, this longitudinal end being received in displacement in the longitudinal direction of the transverse bar, by the head, when adjusting the spacing of the adjustment rails. According to another characteristic of the invention, the hollow cup-shaped head of the adjustment rail has in its front wall, adjacent to the wire basket and projecting from the adjustment rail, an insertion hole for the longitudinal end of the transverse bar, and to this insertion hole of the head is connected an enlarged hollow space open towards the opposite longitudinal side

of the adjustment rail.

  According to another characteristic of the invention, the depth of the hollow space of the head, extending in the longitudinal direction of the transverse bar, between the front wall and the opposite longitudinal side of the rail, provides clearance for the modification of spacing of the adjustment rails. According to another characteristic of the invention, each longitudinal end of the transverse bar is folded to form a hook fitting into the hollow space of the head. According to another characteristic of the invention, each adjustment rail has on its outer longitudinal side, opposite the end head, an insertion notch for the longitudinal bar carrying the wire basket, which ends at each of its longitudinal ends spaced from the two longitudinal bars

and without being connected to them.

  According to another characteristic of the invention, below the insertion notch, on the external longitudinal side of each adjustment rail are provided projections for the passage of the bars of the wire basket.

  protruding down from the longitudinal bars.

  According to another characteristic of the invention, the adjustment rail is molded in one piece from synthetic material. According to another characteristic of the invention, the adjustment rail is fixed, and is preferably riveted, by its longitudinal side outside to a guide rail, of C section, of a sliding and / or rolling guide. covering by fixing the longitudinal bar arranged

in the insertion notch.

  The wire basket guide support according to the invention is formed by an adjustment tab which is installed on the two longitudinal sides of the wire basket and which is connected to a rail on which the

  wire basket removal device.

  The front and rear carrier transverse bars of the wire basket are inserted into the two ends of the opposite adjustment tabs and hook into the tabs with the resulting play in the longitudinal direction of the bars. For different cabinet widths, it is then possible to make an adjustment within a certain range, by pushing or bringing the two adjustment tabs closer to the ends of the transverse bars, so that the width of the wire basket can be adjusted according to the width of the cabinet and guides installed there The longitudinal bars carrying the wire basket are not connected to the transverse load-bearing bars in the vicinity of the corners of the basket, so that flexibility is obtained in the wire basket at the corners, and that when adjusting the spacing of the adjustment tabs, the longitudinal bars of the wire basket which are fixed to them, can be moved acés both outward and inward, the basket wires from the longitudinal bars thus easily bending, which is possible in itself and has no effect on the whole

wire basket.

  This adjustment of the mutual spacing of the adjustment tabs allows, for the same basket dimension,

  to accommodate the difference in width of the cabinets, with little manipulation and without any additional measure35 for extraction.

  The adjustment tabs are made in one piece of synthetic material and take up both the transverse bars and the longitudinal bars of the wire basket in a stable position, and guarantee stable guidance of the basket support. Only one tab model is required for the two longitudinal sides of the wire basket The adjustment tab is easy to install, can be manufactured at low cost and can be fixed to the longitudinal sides of the wire basket with a small number of manipulations ,

  while being able to be connected to the lateral guide rails.

  The idea underlying the invention extends on the one hand to the wire basket with its two adjustment tabs and on the other hand to the adjustment tabs considered as independent parts which can be installed afterwards in furniture. existing, i.e. when new baskets have to be fitted or when the guides have to be modified, or when the existing intermediate parts of the guides have to be removed

extraction.

  An embodiment of the invention is explained in more detail below with the aid of the drawings in which: FIG. 1 is a plan view of a wire basket mounted movably on a rolling guide, with adjustment rails 2 shows a side view from the outside of a longitudinal part of an adjustment rail with a longitudinal bar suspended from a wire basket, and a transverse bar from a wire basket inserted into one end of rail, Figure 3 shows a longitudinal section through the longitudinal part of the adjustment rail of Figure 2, along line II, Figure 4 shows a cross section through an end head of the adjustment rail in which a transverse bar of wire basket is inserted, along line II-II of FIG. 1, FIG. 5 represents a cross section through the adjustment rail in which is inserted a longitudinal bar of the wire basket, along line III-III of Figure 1, Figure 6 shows a side view from the outside of the adjustment rail, Figure 7 shows a plan view, in partial longitudinal section, of the adjustment rail, Figure 8 represents a longitudinal section of the end head of the rail, according to section "A" of FIG. 7, FIG. 9 represents a cross section through the adjustment rail, along line IV-IV of the

figure 6.

  The guide support of a wire basket 2 installed in a removable manner in a cabinet 1 has on the two longitudinal sides of the wire basket 2 an adjustment rail 3, the two adjustment rails 3 each taking a longitudinal end 4 a of the transverse carrier bar 4 front and rear of the wire basket 2; for adjustment to different widths of cabinets, the two adjustment rails 3 hook the longitudinal ends 4 a in a mobile manner and with adjustable spacing. Each adjustment rail 3 has at its two longitudinal ends a hollow head 5 (cup-shaped) and projecting in the direction of the wire basket 2, head 5 into which a longitudinal end 4 a of a transverse bar is inserted, this end being taken up in an adjustable manner by the head 5 when adjusting the spacing of the adjustment rails 3 in the

  longitudinal direction of the transverse bar.

  The hollow head 5 of the adjustment rails 3 has in its front wall 5a adjacent to the wire basket 2 and opposite the adjustment rail 3, an insertion hole 6 of the longitudinal end 4a of the transverse bar; to this insertion hole 6, there is connected a hollow space 7 of the head 5, enlarged and open towards the opposite longitudinal side

adjustment rail 3.

  The depth X of the hollow space 7 of the head 5, in the longitudinal direction of the transverse bar, between the front wall Sa and the longitudinal side 3 a of the opposite rail, forms the clearance for the modification of the spacing of the rails of adjustment 3; in other words, each of the adjustment rails 3; can be moved within this range of

  depth X with respect to the transverse bar 4.

  Each of the longitudinal ends 4 a of the transverse bar is bent into a hook 4 b fitting into

the hollow space 7 of the head 5.

  Each adjustment rail 3 has on its longitudinal side 3 a exterior, opposite the head 5 located at the end a notch 8 for the insertion of the longitudinal bar 9 carrying the wire basket 2, and the longitudinal bar 9 ends at each of its longitudinal ends 9 a at a distance from the two

  longitudinal bars 4, and without being connected to them.

  Below the insertion notches 8, on the outer longitudinal sides of each adjustment rail 3a, there are projections 10 for the passage of the bars 11 of the wire basket projecting below the longitudinal bars 9 Each pair of projections 10 frames a bar 11 projecting downwards The adjustment rail 3 is made in a single piece of synthetic material, of

preferably by injection.

  The adjustment rail 3 extends over the entire length (depth) of the wire basket 2 and is fixed by its external longitudinal sides 3 a to a guide rail 12 with a C section, of a sliding guide 13 and / or bearing, and is preferably riveted thereto, so that the wire basket 2 is fixed inwardly and outwardly displaced to the two adjustment rails 3 and to the two guide rails 12, on rollers 13 or skates of

  guide guide 13 (Figures 1, 4 and 5).

  In Figure 1, only two rollers 13a are drawn on each side, but other rollers 13a are arranged between

  these first for the extraction of the wire basket.

  In FIG. 4, the head 5 is clearly recognized with the adjustment clearance X, and the transverse bar 4 is inserted by its end hooks (4 a, 4 b) into the hollow head 5. The insertion hole 6 has a diameter of dimension such that the transverse bar 4 can be inserted through the hole 6 in the hollow space 7, by its hook 4 b The transverse bar 4 carrying then rests on the lower edge of the hole, and the hook 4 by forms a security preventing extraction, because during an exaggerated increase in the spacing of the two adjustment rails 3 it abuts in front of the front wall a of the head. We recognize in FIG. 5 the longitudinal bar 9 inserted in the insertion notch 8, with a bar 11 of

basket overflowing down.

  This insertion notch 8 is open on the outer side 3a of the adjustment rail 3 and is closed after the insertion of the longitudinal bar 9, by the guide rail 12 riveted on the adjustment rail 3, so that the longitudinal bar 9 is fixed and held in the rail

adjustment 3.

  The two transverse bars 4, with their basket bar 14 projecting downward, are not connected in the vicinity of the four corners of the wire basket 2 to the longitudinal bars 9 and to their basket bar 11 projecting downwards, so that 'in the vicinity of the corners there is a certain flexibility; according to the mutual spacing of the guides 13, which depends on the particular width of the cabinet and the locations where the guides 13 are fixed, the adjustment rails 3 are adjusted to more or less wide spacing, in the longitudinal direction of the bars , relative to the ends of the transverse bars 4 a, this

  which allows you to adjust the width.

  Thanks to the flexibility of the basket in the vicinity of the corners, it is possible to move the longitudinal bars 9 with their bars 11 which protrude downwards towards the outside or inside, as a function of the mutual spacing of the adjustment rails. 3, what

  there is a slight bending of the basket bars 11.

  This modification of the spacing of the longitudinal bars 9 makes it possible to automatically adjust the adjustment rails 3, since these necessarily take up the longitudinal bars 9 fixed in the notches 8 and thus necessarily effect the deformation of the bars 11 of the basket The deformation of the basket bars 11 projecting from the longitudinal bars 9 takes place in the direction of their height, and has no influence or any negative effect on the connection and crossing locations 18 of the bars 11 and 14 at the bottom

from the basket.

  Figures 6 to 9 clearly show the one-piece structure of the adjustment rails 3 with their end heads, the insertion notches 8 which are molded therein, the projections 10 produced by injection, forming between them a slot. 1 Oa passage for a basket bar 11, projecting downwards, molded connecting projections 15, with holes 16, intended for connection to the guide rail 12, and a stiffening cross member

molded 17.

  Supporting and guiding the wire basket is easy to operate when using forced roller guidance on the right and left; in other words, the automatic adjustment is essentially carried out thanks to the fact that the flexible structure of the wire basket allows it to move in the forced guide rails of the basket,

  with a width tolerance of + / 4 mm.

  This holding and this guidance are suitable for roller guides with longitudinal development with automatic stop, with short longitudinal development as well as

  for standard executions without automatic stop.

  The rails 3 are used in lengths of 300 mm, 350 mm, 400 mm, 450 mm, 500 mm and 550 mm.
