Description
The present invention refers to a cabinet or rack body construc-tion adapted to receive a pl~rality of drawers or trays. Particu~
larly the invention concerns cabinets or rack body structures either to be used singly as an individ~al piece of furniture to accomodate a number of drawers or trays within one furniture unit, or to be used in multiplicity, a plurality of single units being combined to a furniture arrangement to accomodate a still greater number of drawers or trays.
Such cabinet or rack body structures of the type mentioned above and known in the prior art comprise at least two essentially flat wall elements, which are horizontally arranged in parallel, spaced relationship, said wall elements forming the side walls of the cabinet or rack body structure. In order to ensure a certain stability in such a structure, at least one essentially hori~on~
talr rigid transverse beam member connected to said at least two opposite side wall elements is provided.
A cabinet body structure of the type mentioned above is described in Swiss Patent Specification No. 474,235. Such cabine~ comprises opposing lateral walls which are interconnected by means of top, bottom and intermediate plate members. These transversly extending plate-like elements are positively supported by the lateral walls in a direction parallel with the plane thereofO Although this arrangement may provide adeq~ate support against vertical loadinq, there is nothing to prevent the lateral walls from tilting, lea-ding to a parallelogram-like deformation of the whole cabinet body. In order to avoid this undesirable effect, the known con-struction according to the Swiss Patent Specification makes use of separate corner joint members adapted to engage with the front and rear edges. These corner joint members may have the form of clamps placed in the corner areas of the above mentioned plate-like elements. This not only involves the substantial costs of separa-tely producing such relatively complex corner joint members, but also means that the side walls as well as the transverse plate-like elements m~st be specially shaped and adapted, if the gene-rally desired countersunk, smooth arrangement of the connecting elements is to be achieved.
It is a major object of the present invention to provide a cabinet or rack body structure of the kind mentioned above which is of a very simple design and requires only a comparatively small amount of time to be assembled. A further object of the invention is to provide a cabinet or rack body structure of extremely rigid con-str~ction avoiding the danger of any deformation of the cabinet or rack body at right angles to the wall elements. A still further object of the invention is to provide a cabinet or rack body structure consisting of a plurality of sinyle cabinet or rack body units adapted to be combined to a furniture arrangement~ either in horizontal and~or in vertical alignment to each other, in a very simple and straight forward manner.
The present invention provides a cabinet or rack body ~tructure adapted to receive a plurality of drawers or trays~ The structure comprises at least two essentially flat wall elements, which are horizontally arranged in parallel~ spaced relationship, the wall elements forming the side walls of the cabinet or rack body struc-~..
. . .
ture. Further it comprises at least one essentially horizontal,rigid transverse beam member connected to the t~o OppGsite side wall elements.
In order to provide the desired stability of the structure, it comprises first locking connection means adapted to connect the free ends of the transverse beam member to the two side wall mem-bers, said first locking connection means including first locking members incorporating two rigid, essentially convexly shaped locking surfaces and second locking members incorporating two rigid, essentially concavely shaped locking surfaces adapted to positively engage said locking surfaces of said first locking members.
One of the first or second locking members is mounted on the inner surface of the side wall elements and the other one of the first or second locking members is mounted on the free ends of the transverse beam member.
In 2 preferred embodiment the locking surfaces of the first and second locking members are arranged essentially at right angles to the inner surface of the side wall elements. Thereby it may be advantageous that the two convexly shaped locking s~rfaces and the two concavely shaped locking surfaces are arranged essentially along a line running parallel with the plane of a drawer or a tray to be inserted into the cabinet or rack body structure.
The above mentioned preferred embodiment may be further characte-rized in that the side wall elements comprise at least one elon gate, strip-shaped supporting web mounted at the inner surface thereof and extending essentially along the whole width of the wall element.
The convexly shaped locking surfaces are constituted by opposite surfaces of the two end regions of the supporting web, and i may include a panel-like portion protruding from the web to the inte-rior of the structure and ex~end essentially along the major part of the web, said convexly shaped locking surfaces being constitu-ted by end portions of said panel-like portion.
In order to interconnect a plurality of cabinet or rack body units side by side in horizontal alignment, the surface sf each wall element opposite to the supporting web may comprise a grooved recess extending within the cross-sectional height and the length of said supporting web.
To further improve the rigidity of the structure, the side wall elements may comprise at least one transverse stiffening rib in the region of the supporting web.
A still further improved rigid structure may be achieved when the two end portions of the panel-like portion forming said convexly shaped locking surfaces comprise an undercut adapted to receive a locking element provided at the free ends of the transverse beam member.
In order to form a simple, reliable self-lockiny wedge connection, the convexly shaped locking surfaces of the first locking mem-bers as well as the concavely shaped locking surfaces of the se-cond locking members are inclined in an acute angle.
It may be desired to arrange a plurality of cabinet or rack body units one superimposed on the other one to form a larger furni-ture arrangement for accommodating a greater number of drawers or trays. In order to favour such arrangement, the side wall elements may urther comprise a second supporting web arranged along the upper edge and protruding inwardly from the inner surface thereof to receive and support such a superimposed cabinet or rack body structure.
Of course it must be assured that all the cabinet or rack body units placed one on the top of another one are securely fixed relative to each other to avoid any unintended displacement~ For this reason the side wall elements may comprise at least one first stop member arranged on the top surface of the second supporting web and with a certain distance to the outer surface of the side wall element, and at least one second stop member arranged in the region of the lower edge of the side wall element. The first stop member of a firs~ rack body structure is adapted to cooperate with the second stop member of a second, superimposed rack body struc-ture to positively position said second rack body struct~re in relation to said first rack body structure. Preferably at least one of said first and sec~nd stop members is a part of one of the first supporting webs.
In a further preferred embodiment of the cabinet or rack body structure, there is provided at least one transverse member in-cluding a central, resiliently flexible area, which i6 mounted at two opposite end portions to the corresponding side wall ele-ments by means of second locking connection means. These include a plurality of recesses arranged on the inner surface of the side wall elements as well as a plurality of correspondingly shaped protrusions provided at the free ends of ~he transverse member.
Preferably the transverse member is in the form of a flat plate element with a resiliently flexible central area adapted to support a drawer or a tray.
The central area of the transverse member may have a smaller cross-sectional width than the two end portions, whereby at least a part of the front and/or rear edge of the transverse member extends obliquely to the direction of displacement of a drawer or tray. This may be realized if the front and/or rear edge of the transverse member includes sloping portions converging rom both sides towards the central area thereof.
A cabinet or rack body structure having one or more storage com-partments which are open in two opposite directions may be formed by a corresponding number of rigid transverse beam members and/or by a corresponding number of resiliently flexible tr~nsverse mem-bers and by two side wall elements.
An especially preferred embodiment of the invention may be seen in a rack body structure which includes two or more rack body units adapted to receive a plurality of drawers or trays and which are (~ ., ":
~ 3~
placed side by side in horizontal alignment or one above the other one in vertical alignment. Thereby each rack body unit comprises two essentially flat wall elements, which are horizontally arran-ged in parallel, spaced relationship, said wall elements forming the side walls of the rack body structure. At least one essential-ly horizontalr rigid transverse beam member connected to said two opposite side wall elements ensures the desired stability of the structure. There are provided first locking connection means adapted to connect the free ends of the transverse beam member to the two side wall members, said first locking connection means including first locking members incorporating two rigid, essen-tially convexly shaped locking s~rfaces and second locking members incorporating two rigid, essentially concavely shaped loclcing surfaces adapted to positively engage said locking surfaces of said first locking members.
One of the first or second locking members is mounted on the inner s~rface of said side wall elements and the other one of the first or second locking members is mounted on the free ends of the transverse beam member. Each of said side wall elements comprises at least one elongate~ strip-shaped supporting web mounted at the inner surface thereof and extending essentially along the whole width of the wall element~ wherein the surface of the wall element opposite to said supporting web comprises a grooved recess ex-tending within the crosssectional height and the length of said supporting web. The grooved recess is in the form or a concavely shaped locking member adapted to receive and positively engage with a convexly shaped locking member to interconnect the side wall elements of two adjacen~ rack body units.

As can be seen from Fig~ 19 3 and 4 the rack body structure comprises two side wall elements 1 arranged in spaced relationship parallel to each other. The side wall elements 1 are rigidly in-terconnected by means of a n~mber of transverse beam members 2, the ends thereof being connected to supporting webs 3 mounted on the inner surface of the side wall elements 1 and preferably being integral therewith. The connection between supporting web 3 and transverse beam member 2 is realized by means of locking connec-tions, generally designated with reference numeral 4. In the embo-diment shown in Fig. 4 the transverse beam members 2 are arranged on both side wall elements 1 pairwise at the same level with rela-tion to the planes E-E of the drawers to be inserted, parallel with each other and in spaced relationship to each other. Thereby a rigid and extremely strong support for ~he two side wall ele~
ments 1 is provided.
A compartment 5 for receiving a drawer or a tray is formed between two superimposed pairs of transverse beam members 2 and also on the top surfaces of the uppermost pair of transverse beam members

ture. Further it comprises at least one essentially horizontal,rigid transverse beam member connected to the t~o OppGsite side wall elements.
In order to provide the desired stability of the structure, it comprises first locking connection means adapted to connect the free ends of the transverse beam member to the two side wall mem-bers, said first locking connection means including first locking members incorporating two rigid, essentially convexly shaped locking surfaces and second locking members incorporating two rigid, essentially concavely shaped locking surfaces adapted to positively engage said locking surfaces of said first locking members.
One of the first or second locking members is mounted on the inner surface of the side wall elements and the other one of the first or second locking members is mounted on the free ends of the transverse beam member.
In 2 preferred embodiment the locking surfaces of the first and second locking members are arranged essentially at right angles to the inner surface of the side wall elements. Thereby it may be advantageous that the two convexly shaped locking s~rfaces and the two concavely shaped locking surfaces are arranged essentially along a line running parallel with the plane of a drawer or a tray to be inserted into the cabinet or rack body structure.

resiliently flexible transverse member~
As can be seen from Fig~ 19 3 and 4 the rack body structure comprises two side wall elements 1 arranged in spaced relationship parallel to each other. The side wall elements 1 are rigidly in-terconnected by means of a n~mber of transverse beam members 2, the ends thereof being connected to supporting webs 3 mounted on the inner surface of the side wall elements 1 and preferably being integral therewith. The connection between supporting web 3 and transverse beam member 2 is realized by means of locking connec-tions, generally designated with reference numeral 4. In the embo-diment shown in Fig. 4 the transverse beam members 2 are arranged on both side wall elements 1 pairwise at the same level with rela-tion to the planes E-E of the drawers to be inserted, parallel with each other and in spaced relationship to each other. Thereby a rigid and extremely strong support for ~he two side wall ele~
ments 1 is provided.
A compartment 5 for receiving a drawer or a tray is formed between two superimposed pairs of transverse beam members 2 and also on the top surfaces of the uppermost pair of transverse beam members
2. These compartments are open at the end-faces 6 arranged to face each other and provide a continuous cross-sec~ional height ~o throughout. The drawers or trays may thus be introduced into the compartment at will from either side. ~6 a whole, the cabinet body is also symmetrically designed in relation ~o the opposi~g end faces 6, so that there is no restriction as to the location of the side from which the drawers or trays are operated. Furthermore it is possible to use drawers having only half depths, facing each other and being inserted each from opposing end-faces 6; al~hough ~his emb~diment is not explicitely shown in the drawings.
Compartments 5 may also be provided with closed bottom surfaces by means of panel-like transverse members~ to be further explained hereinafter, or by means of panel-likel rigid transverse beam members, similar to the members 2 mentioned hereinbefore Such arrangement provides ~torage compartments 5 particularly for small objects; if desired these compartmen~s may also be equipped with a drawer or a tray.
In Fig. 3 and 4 a drawer is diagrammatically shown in the plane of the lowermost transverse beam members 2, the height of the drawer corresponding to the distance between the superimposed transverse beam members 2 and supporting webs 3, the lateral edges of the drawer projecting downwardly beyond the bottom wall thereof resting upon the supporting webs 3. This provides reliable gui-dance for the drawer, even if it is pulled out relatively far.
The bottom of the rack body structure is not closed, but termina-ted only by the transverse beam members 2, whereas the top of the rack body structure is terminated by a superimposed rack body structure (only partly shown in Fig. 3 to 5). In order to positi-vely support a superimposed rack body struct~re, there is provided a second supporting web 7, projecting at right angle to the side wall element 1 towards the interior of the rack body structure.
Preferably such supporting web 7 is arranged integrally with the upper edge 8 of the side wall elements 1 and is equipped with the upwardly projecting first stop element 9 which is adapted to posi-tion superimposed rack body structures in relation to each other. A second stop element 10 of complementary design with re-gard to the first stop element 9 is provided in the region of ~he bottom surface of each side wall element 1 and may simply be in the form of a section of the integral surface of the relevant supporting web 3O As shown in Fig. 3 and 4, each pair of such first and second stop elements 9 and 10 respectively forms a posi-tive stop connection in two horizontal directions at right angles to each other in such a manner that two s~perimposed rack body structures are securely fixed and positioned in any direction.
Obviously if only one rack body structure is to be set up, a suitable terminating panel incorporating second stop elements 10 may be provided to close the top surface of the said single rack body structure (not shown in the drawings).
As similar locking arrangement with mutual positioning ~ay also be provided for rack body structures located side by side in horizontal alignment. To this end~ as shown in Fig. 3, the side wall elements 1 are equipped with recessed grooves 11 on their outer surface, i.e. the surface opposite to the supporting webs
Compartments 5 may also be provided with closed bottom surfaces by means of panel-like transverse members~ to be further explained hereinafter, or by means of panel-likel rigid transverse beam members, similar to the members 2 mentioned hereinbefore Such arrangement provides ~torage compartments 5 particularly for small objects; if desired these compartmen~s may also be equipped with a drawer or a tray.
In Fig. 3 and 4 a drawer is diagrammatically shown in the plane of the lowermost transverse beam members 2, the height of the drawer corresponding to the distance between the superimposed transverse beam members 2 and supporting webs 3, the lateral edges of the drawer projecting downwardly beyond the bottom wall thereof resting upon the supporting webs 3. This provides reliable gui-dance for the drawer, even if it is pulled out relatively far.
The bottom of the rack body structure is not closed, but termina-ted only by the transverse beam members 2, whereas the top of the rack body structure is terminated by a superimposed rack body structure (only partly shown in Fig. 3 to 5). In order to positi-vely support a superimposed rack body struct~re, there is provided a second supporting web 7, projecting at right angle to the side wall element 1 towards the interior of the rack body structure.
Preferably such supporting web 7 is arranged integrally with the upper edge 8 of the side wall elements 1 and is equipped with the upwardly projecting first stop element 9 which is adapted to posi-tion superimposed rack body structures in relation to each other. A second stop element 10 of complementary design with re-gard to the first stop element 9 is provided in the region of ~he bottom surface of each side wall element 1 and may simply be in the form of a section of the integral surface of the relevant supporting web 3O As shown in Fig. 3 and 4, each pair of such first and second stop elements 9 and 10 respectively forms a posi-tive stop connection in two horizontal directions at right angles to each other in such a manner that two s~perimposed rack body structures are securely fixed and positioned in any direction.
Obviously if only one rack body structure is to be set up, a suitable terminating panel incorporating second stop elements 10 may be provided to close the top surface of the said single rack body structure (not shown in the drawings).
As similar locking arrangement with mutual positioning ~ay also be provided for rack body structures located side by side in horizontal alignment. To this end~ as shown in Fig. 3, the side wall elements 1 are equipped with recessed grooves 11 on their outer surface, i.e. the surface opposite to the supporting webs
3 extending within the cross-sectional height and the length of the supporting web 3. The recessed grooves 11 are therefore in the form of U-shaped hollow bodies of corresponding cross-sectional height and providing connections of considerable flexural strength with the panels of the wall elements 1. As can be seen from Fig. 6, -the groove 11 receives positioning elemen-ts 12, the free protruding ends thereof engaging in corresponding recessed grooves in an adjacent rack body structure. In order to provide an increased stiffness to the side wall elements 1, transverse ribs 13 are arranged along the recessed groove 11. Furthermore, if the wall elements 1 are in the form of moulded or injection-moulded panels of synthetic material, the recessed grooves 11 offer the advantage of eliminating accumulations of material with the attendant danger of cold shrinkage and surface impairment.
As may be seen from Figs.2, ~ and 5, the supporting webs 3 have a decreasing cross-sectional height with a wider portion adjacent to the surface of the corresponding side wall elements 1 and a narrower portion towards the interior of the rack body structure. The longitudinal edge of the narrower portion of the supporting webs 3 incorporates a panel-like section 14 which extends over a major part of the length of said webs 3 (see also Fig. 6). Basically, the whole length of this panel-like section 14 might be used as a convexly shaped locking member for the attachment of the transverse beam members 2.
However, in the present embodiment, only the two end portions of the panel-like web sections 14 are used as conve~ly shaped locking members 15 engaging with corresponding concavely shaped locking members 16 at the free ends of the transverse beam members 2, as can be clearly seen from the exploded view shown in Fig. 2~
Fig. 7 shows the possibility to provide a side wall element 1' on opposite surfaces with supporting webs 3'. The partial front elevation illustrated in Fig. 7 shows a portion of the wall ele-ment 1' having a pair of supporting webs 3' arranged at the same height level and protruding in opposite directions from the cor-responding wall element surface. As compared with the supporting webs 3 of the previously discussed design, the cross-sectional shape of the webs 3' in Fig. 7 is simplified and consists merely of a plate-like web section 1~'. However, as in the previous design, convexly shaped locking members 15 are formed on the front and rear ends of the section 14' as well. In both designs stif~
fening ribs 17 are provided in the region of the convexly shaped locking members 15, on the one hand on the wall element 1 and 1', respectively, and on the other hand on the panel-like section 14 and 14' respectively. This arrangement increases the flexural strength of the said web sections and locking members. Especially in the design according Fig. 7 such an arrangement is essential because the supporting web 3' is comparatively narrow and thin in order to reduce accumulations of material and possesses per se a certain amount of flexural strength.
comparatively narrow strip 18 may be provided in an area between transverse beam members 2 as a support and guide member for the drawers 19. With supporting webs 3' on both sides of a wall ele-ment 1' it is a simple matter to assemble battery-like multiple rack body structures.
As can be seen from Fig. 8 and 9 the transverse beam members 2 are designed as U-shaped profiled elements incorporating transverse stiffening ribs 20 in order to increase the flexural strength and rigidity of the transverse beam members 2. The end sections of the interior of the U-profile shaped transverse beam members 2 serve as the previously mentioned concavely shaped locking members 16.
As can be seen from Fig. 6, these end sections are pressed onto the end sections of the panel-like sections 14, which in turn serve as convexly shaped locking members 15~ As a result of the acute angled arrangement Inot shown) of opposing locking surfaces 21 and 22 of corresponding locking members 15 and 16, the locking connection means thereby formed provides a self-locking clamping action, thus providing a reliable, rigid wedge connection between the transverse beam members 2 and the wall elements lo It is to be understood that the pairs of locking surfaces 21 and 22~ respecti-vely, converge at an acute angle in a direction opposite to the direction of engagement of the transverse beam members 2, i.e~
with reference to Fig. 6, outwardly in the direction from the interior of the rack body structure and parallel with a plane of the wall elements 1~
As can be seen from Fig~ 4 the convexly shaped locking web members 15 are arranged upon a line X-X running parallel with a plane E-E
of the drawers 19, so that the transverse beam members 2 are also arranged at the same height in relation to the plane of the drawers 19 and are therefore included in the entire surface ser-ving to support the relevant drawer. As a result of the use of the end portions of the panel-like section 14 of each supporting web 3 as locking members, the later are also arranged in parallel align-ment with a plane of the drawers 19 and may therefore be relative-ly long. This assures adequate flexural strength and rigidity inspite of the comparatively small cross-sectional height of the locking members 15.
Furthermore the embodiment as described hereinbefore provides a positive anchoring of the transverse beam members 2 to the wall elements 1 with respect to forces acting along the axes of the transverse beam members 2. To this end the convexly shaped locking members 15 are provided with undercuts 23 in which form locking elements 24 at the ends of the transverse be~m members 2 engage.
These locking elements 24 are designed merely as terminating walls of the ~-shaped profile of the transverse beam members 2 and therefore req~ire no additional shaping thereofe FigO 3 to 5 show the arrangement of an intermediate compartment 25 within the height distance of two transverse beam members 2 with relevant sup~orting webs 3 in the form of a comparatively thin-walledl plate-like transverse member 26~ In order ~o connect these transverse members 26 to the wall elements 1 there are provided locking connections 27 consisting of sectionally projecting edge portions 28 at the free ends of the transverse members 26, on one hand, and corresponding openings 29 at the inner surface of the wall elements 1 on the other handO These transverse members 26 have a resiliently flexible central Area and therefore may be easily inserted into an assembled rack body structure by bending them in order to insert the edge portions 28 into the openings 290 Fig. 10 shows a simple way to realize the desired fle~ibility of the transverse member 26, namely by reducing the cross-sectio~al width (as mesured in the direction of insertion) along the central portion of the body of the transverse member 26 in relation to the edge portions thereof. This reduction of the contour may be rea-lized, if desired, by a suitable opening in the central portion of the transverse member 26 (not shown). However, the reduction of the width of the body of the transverse member 26 in the region of its central axis Y-Y according to the embodiment shown in Fig. 10 provides the substantial advantage that it i5 impossible for the drawer to strike against a possibly upwardly or downwardly projec-ting transverse edge of the member 26s because such edges run at acertain angle to the central axis Y-Y as well as to the direction of displacement of the drawer.
In the event of any deformation of the rack body structure, a slight upward and/or downward sagging must be expected because of the flexibility of the body of the transverse member 26 under certain circumstances, and this might produce such an impact. The proposed shaping of the transverse member 26 than forms run-up edges which show slightly upwardly and which are easily passed over during insertion of the drawer by the transverse edyes on the bottom surface thereof. The same applies to the rear edye 30 when the drawer is pulled out, and also when half-size drawers are inserted and/or pulled out from opposite sides of the rack body ~tructure.
.
As may be seen from Figs.2, ~ and 5, the supporting webs 3 have a decreasing cross-sectional height with a wider portion adjacent to the surface of the corresponding side wall elements 1 and a narrower portion towards the interior of the rack body structure. The longitudinal edge of the narrower portion of the supporting webs 3 incorporates a panel-like section 14 which extends over a major part of the length of said webs 3 (see also Fig. 6). Basically, the whole length of this panel-like section 14 might be used as a convexly shaped locking member for the attachment of the transverse beam members 2.
However, in the present embodiment, only the two end portions of the panel-like web sections 14 are used as conve~ly shaped locking members 15 engaging with corresponding concavely shaped locking members 16 at the free ends of the transverse beam members 2, as can be clearly seen from the exploded view shown in Fig. 2~
Fig. 7 shows the possibility to provide a side wall element 1' on opposite surfaces with supporting webs 3'. The partial front elevation illustrated in Fig. 7 shows a portion of the wall ele-ment 1' having a pair of supporting webs 3' arranged at the same height level and protruding in opposite directions from the cor-responding wall element surface. As compared with the supporting webs 3 of the previously discussed design, the cross-sectional shape of the webs 3' in Fig. 7 is simplified and consists merely of a plate-like web section 1~'. However, as in the previous design, convexly shaped locking members 15 are formed on the front and rear ends of the section 14' as well. In both designs stif~
fening ribs 17 are provided in the region of the convexly shaped locking members 15, on the one hand on the wall element 1 and 1', respectively, and on the other hand on the panel-like section 14 and 14' respectively. This arrangement increases the flexural strength of the said web sections and locking members. Especially in the design according Fig. 7 such an arrangement is essential because the supporting web 3' is comparatively narrow and thin in order to reduce accumulations of material and possesses per se a certain amount of flexural strength.
comparatively narrow strip 18 may be provided in an area between transverse beam members 2 as a support and guide member for the drawers 19. With supporting webs 3' on both sides of a wall ele-ment 1' it is a simple matter to assemble battery-like multiple rack body structures.
As can be seen from Fig. 8 and 9 the transverse beam members 2 are designed as U-shaped profiled elements incorporating transverse stiffening ribs 20 in order to increase the flexural strength and rigidity of the transverse beam members 2. The end sections of the interior of the U-profile shaped transverse beam members 2 serve as the previously mentioned concavely shaped locking members 16.
As can be seen from Fig. 6, these end sections are pressed onto the end sections of the panel-like sections 14, which in turn serve as convexly shaped locking members 15~ As a result of the acute angled arrangement Inot shown) of opposing locking surfaces 21 and 22 of corresponding locking members 15 and 16, the locking connection means thereby formed provides a self-locking clamping action, thus providing a reliable, rigid wedge connection between the transverse beam members 2 and the wall elements lo It is to be understood that the pairs of locking surfaces 21 and 22~ respecti-vely, converge at an acute angle in a direction opposite to the direction of engagement of the transverse beam members 2, i.e~
with reference to Fig. 6, outwardly in the direction from the interior of the rack body structure and parallel with a plane of the wall elements 1~
As can be seen from Fig~ 4 the convexly shaped locking web members 15 are arranged upon a line X-X running parallel with a plane E-E
of the drawers 19, so that the transverse beam members 2 are also arranged at the same height in relation to the plane of the drawers 19 and are therefore included in the entire surface ser-ving to support the relevant drawer. As a result of the use of the end portions of the panel-like section 14 of each supporting web 3 as locking members, the later are also arranged in parallel align-ment with a plane of the drawers 19 and may therefore be relative-ly long.

Furthermore the embodiment as described hereinbefore provides a positive anchoring of the transverse beam members 2 to the wall elements 1 with respect to forces acting along the axes of the transverse beam members 2. To this end the convexly shaped locking members 15 are provided with undercuts 23 in which form locking elements 24 at the ends of the transverse be~m members 2 engage.
