Definitions
- the invention relates to a cabinet or frame body, in particular for receiving drawers or drawers, comprising a plurality of flat wall elements arranged opposite one another and at least one cross member that crosses the space between two wall elements and connects these wall elements to one another in a positive or non-positive manner at least one surface side of each wall element, at least one locking connection is provided for the cross member.
- the invention further relates to a set of components for cabinet or frame bodies, in particular for receiving drawers or drawers.
- a cabinet body of the type mentioned is known from CH-PS .474235. There are opposite. Side walls of the cabinet body. Connected to one another by floor and ceiling parts and intermediate floors, these plate-shaped transverse elements being positively supported on the latter in the direction parallel to the plane of the side walls. Although this results in a sufficient load-bearing capacity against vertically acting loads, the side walls are not secured against tipping and thus against a parallelogram-like deformation of the entire cabinet body.
- rather special corner connections are provided, which encompass the front and rear edges of the side walls of the plate-shaped transverse elements in the corner regions of their joints with clamping members. This not only requires special manufacturing effort for the comparatively complicated shaped corner connecting elements, but also makes it necessary to adapt and shape the side walls and transverse elements if the generally desired, recessed and smooth surface arrangement of the connecting elements is to be achieved.
- the object of the invention is therefore to create a cabinet body and a corresponding set of components ; in which a simple construction and comparatively little installation effort and a positive locking against deformation of the cabinet body can be achieved transversely to the wall elements.
- the solution to this problem according to the invention is characterized in terms of the cabinet body and the component set by the features of claims 1 and 24, respectively.
- the latching exclusion provided thereafter enables the wall elements to be supported against one another in a rigid manner, the convex latching elements being formed, for example, on the wall element and acting as cantilever arms which in turn are rigidly connected to the associated cross members.
- the wings of the latching elements are arranged at least approximately at right angles to the plane of a wall element and in pairs opposite to one another. This results in a rigid locking connection, the elements of which can be easily inserted into the cross-sectional height of the cross member. This improves the proportion of usable space.
- a plurality of cross members are provided on a wall element, each with a latching connection at both ends.
- cross beams with a larger cross-sectional width can also be considered, for example plate-shaped, rigid cross beams which overlap a larger part of the width of the wall elements on both sides and are each provided with a plurality of snap-in connections on both side edges.
- plate-shaped, rigid cross members can be used in particular as storage compartments without drawers. In this way, frame bodies of simple construction can be obtained despite the large number of compartments.
- At least two cross members with corresponding locking elements are arranged on the wall elements on a line running parallel to a drawer or drawer level and can optionally serve directly as a drawer support and guide. It is generally advantageous to arrange the wings of the convex and concave locking elements at least approximately parallel to the drawer or drawer level. This measure results in a comparatively small height dimension of the connecting elements and a reduction in the unused cabinet interior.
- the convex latching elements are designed as sections of a strip-shaped supporting web extending parallel to the drawer or drawer level. This not only simplifies the shape and thus the manufacture of the supporting webs, but also enables a large number of cross members to be attached to such a supporting web without any particular effort, without separate latching elements having to be formed for the individual connection points.
- the anchoring of the cross beams on the wall elements against tensile forces in the longitudinal direction of the beams can in principle be non-positive, i.e. can be achieved by sufficient clamping and static friction between the wings of the convex and concave locking elements.
- an acute-angled arrangement of the oppositely oriented wings of the complementary locking elements is recommended, forming a self-locking wedge connection within each locking connection.
- Such a connection can be assembled in a simple manner by pressing it together, generally by hand without special tools.
- the cabinet body it is particularly advantageous for the cabinet body to be positively anchored to the cross members on the wall elements for greater stresses.
- a further development of the invention provides that at least one of the convex latching elements has an undercut for the attack of a form-locking locking element formed on the associated cross member at right angles to the wall plane. Assembling is particularly easy here because the clamping force and thus that of Assembling the snap-in connection resistance to be overcome can be kept low due to correspondingly weak dimensioning of the wedge effect. If necessary, the oppositely oriented wings of the latching elements can be arranged in parallel and thus be executed without wedging in the interest of particularly easy assembly.
- An essential development of the invention is aimed at accommodating drawers or drawers of comparatively low height within the cabinet body.
- Such low push elements which are also provided in large numbers one above the other, for example in the form of plate-shaped drawers without side borders, for example with receptacles for small parts, would require a comparatively large overall cross-section when stored on rigid cross members of comparatively large cross-section and thus result in an undesirable loss of usable cabinet space.
- the development of the invention therefore provides - in general in addition to at least one rigid cross-member - at least one cross member, which is designed to be elastic and flexible in its central region and is connected at two opposite end sections by snap-in connections to the wall elements of the cabinet body on both sides Formation enables a very low cross-sectional height and thus a small additional space requirement, whereby the storage and support of the drawers takes place directly at the end sections of the cross members connected to the wall elements by snap connections.
- the softness of the transverse links does not have a disturbing effect on the weight of the drawer.
- the corresponding relief of the central section and thus of the entire cross member from bending moments due to the load absorption results automatically from the interaction of the vertically rigid locking connections with the vertical flexibility of the central cross member section.
- the elastic-flexible design of the cross members enables the cross members to be mounted in an already assembled cabinet body in a particularly advantageous manner.
- a cross member is bent out of its flat shape by hand and thus shortened in its transverse dimension, so that it can be easily inserted into the width of the cabinet interior.
- the end sections of the cross member can then be easily inserted into the associated wall element recesses of the latching connections, whereupon the engagement into the recesses of the opposite wall element takes place by releasing the elastic deformation and returning to the flat shape of the cross member.
- the corresponding flexural softness can be achieved particularly simply by reducing the load-bearing cross-sectional length in the central region of the plate body of such a cross member.
- a cabinet or frame body of the present type at least one receiving compartment which is open in two opposite directions and which is formed by at least one rigid cross member and / or at least one elastic-flexible cross member in connection with wall elements on both sides.
- a receiving compartment which is open in opposite directions, or a plurality of such compartments enable the cabinet or frame to be used and operated in any manner from both opposite end faces.
- These compartments can be used for storage accessible from both sides or for passing objects, such as documents, between the front sides of the cabinet or frame.
- Such use proves to be particularly useful in the case of extensive cupboard or frame arrangements, for example of cupboard or frame walls, between two mutually opposite workplaces.
- such a storage compartment which is open on both sides, can optionally also be used for inserting half-drawers oriented in opposite directions.
- the design of the cabinet or frame body which is symmetrical with respect to the opposite end faces, provides an arbitrary thrust Shelf use with operation from one side or the other enables.
- the different requirements for cupboard or rack space at two workplaces located opposite one another can be flexibly taken into account. Overall, this results in a significant expansion of the area of application and an improvement in adaptability with regard to different operating conditions.
- the set of components for cabinet bodies belonging to the subject of the invention due to its identification features, consists only of flat bodies of comparatively small cross-sectional height, namely the flat wall elements and the same cross members and cross members. This offers the particular advantage of collapsibility and packaging with a small footprint in the form of a compact flat body.
- the cabinet body consists of wall elements WE on both sides with cross members QT, which ver at their ends with support webs TS of the wall elements by snap connections RS are covenants.
- the cross members are arranged in the manner shown in FIG. 2 at the same height with respect to the drawer levels EE and parallel to one another and at a mutual distance within the interior of the cabinet, so that there is a rigid and high-strength support of the two wall elements against one another.
- a receiving compartment FC for a drawer is formed between the pairs of crossbeams on top of each other and on the top of the top pair of crossbeams. These compartments are open on the mutually oppositely oriented end faces ST and have the same clear cross-sectional height throughout. The drawers can therefore be inserted from either side.
- the cabinet body is also symmetrical with respect to the opposite end faces ST, so that there are no restrictions with regard to the arrangement of the operating side of the drawers. It is also possible to use half-drawers oriented in opposite directions, which is not shown in the drawings.
- the receiving compartments FC can be provided with closed bottom surfaces. This results in storage compartments that can also be used for small items, which can optionally also be used for the use of drawers.
- FIGS. 1 and 2 a drawer S with a height corresponding to the distance one above the other - crossmembers and supporting webs lying one above the other, which is supported on the supporting webs TS with their side edges projecting downward over the bottom of the drawer, is schematically indicated in FIGS. This results in a safe guidance of the drawer even in a relatively extended position.
- the lower end of the cabinet body is formed solely by the cross member, while the top is closed by an adjacent, mounted cabinet body (only partially indicated in Fig. -1 to 3).
- a support web AS projecting transversely to the wall level and to the inside of the cabinet body is integrally formed on the upper edge OK of the wall elements and provided with a strip-shaped, upwardly projecting first stop element ASO for securing the position of the stacked cabinet body against one another.
- a complementary second stop element ASU is provided on the underside of the upper cabinet body and, as a result of the matching design, also at the corresponding point on the lower cabinet body, in a simple manner as an inner surface section of the supporting web TS in question.
- a pair of such first and second stop elements each form, in the manner shown in FIGS. 1 and 2, a positive stop connection in two horizontal directions that are perpendicular to one another, so that the two cabinet bodies secure the position on all sides exhibit.
- a suitable end plate for example, provided with stop elements AS U
- stop elements AS U for the top of the cabinet body can be provided for the individual installation of a cabinet body (not shown).
- a corresponding connection option and mutual securing of position also results for cabinet bodies which are arranged laterally adjacent.
- groove-shaped recesses NT are formed on the surface of the wall elements WE opposite the support webs TS in the region of the individual support webs. The latter extend within the cross-sectional height and the length of the supporting webs, so that the latter represent U-shaped hollow bodies with a corresponding cross-sectional height and great bending strength in their connection with the plate body of the wall element.
- Position securing elements LS are inserted into the groove-shaped recesses NT, as shown in FIG. 4, which engage in corresponding recesses — the neighboring cabinet body.
- the recesses NT are provided with distributed crosspieces QS in the interest of the rigidity of the wall element plate body.
- the recesses also have the advantage when producing the wall elements as plastic pressed parts or molded parts that material accumulations with the risk of corresponding cooling shrinkage and surface impairment are eliminated.
- the support webs TS have one of the following as a result of the U-shaped profiling mentioned.
- the entire length of this plate-shaped section is suitable for puncturing a convex locking element for connecting cross beams.
- only the end portions of the plate-shaped web portion PL on both sides are provided as convex locking elements REX for engaging corresponding concave locking elements REV on the cross beam ends.
- FIG. 5 shows the possibility of providing a wall element WE 1 on both opposite surface sides with strip-shaped support webs TS.
- the partial front view shown shows an area of the wall element with supporting webs arranged at the same height and oriented opposite to one another, the cross-sectional shape of which is simplified compared to the supporting webs TS of the previously described embodiment and is essentially formed only by a plate-shaped web section PL.
- convex locking elements REX are in turn molded as in the previous embodiment.
- stiffening ribs QV are on the wall body on the one hand and on the web section PL molded on the other.
- the supporting web TS1 is designed as a comparatively narrow and thin strip, in order to keep material accumulations to a minimum, which in itself has a certain bending strength.
- a comparatively narrow strip attachment P can also be provided as a support and guide for the drawers in the area between the cross members QT.
- the cross beams are formed in the manner shown in FIGS. 6 and 7 as a U-profile body with stiffening transverse ribs V, which increases the bending strength and bending stiffness.
- the end sections of the profile interiors form the cross members in the manner shown in FIG. 4 with their open profile sides pressed toward the cabinet interior onto the convex locking elements REX.
- the latching elements have a self-locking effect, thereby creating a secure wedge connection between the cross members and the wall elements.
- the wing pairs each converge at an acute angle opposite to the direction of arrival of the crossbeams, that is to say with respect to FIG. 4 in the direction from the interior of the cabinet to the outside and parallel to the plane of the wall elements WE.
- the locking elements REX are arranged on a line X-X running parallel to the drawer plane E-E, so that the cross members are also arranged at the same height with respect to the drawer plane and therefore fit into the entire wing for supporting the associated drawer.
- the use of sections of the plate-shaped section PL of each support web TS as locking elements has the consequence that the latter are also arranged parallel to the drawer plane and can therefore have a comparatively large width. Despite the comparatively small cross-sectional height of the REX locking elements, this results in sufficient bending strength and bending stiffness.
- undercuts HS are formed on the convex locking elements REX, into which form-locking locking elements VR engage at the ends of the cross members.
- These locking elements are simply designed as end walls of the U-profile of the cross member and therefore do not cause any additional shaping effort.
- FIGS. 7 shows a simple way of setting the suitable bending softness, namely by reducing the cross-sectional length (measured in the direction of insertion) in the central region of the plate body compared to the edge sections.
- a corresponding recess can optionally be used.
- the constriction of the depth dimension of the plate body in the region of its central axis YY indicated in the example gives the essential advantage that, as a result of the sections of the front edge VK which run obliquely to the axis YY or the direction of movement of the drawer, the drawer does not hit an approximately upward side and the above transverse edge of the plate body can occur. If there is any tension in the cabinet body, the panel body must be flexible due to the flexibility of the panel. U. and a slight deflection may be expected and that could cause such a nudge.
- the present contour then, however, forms slightly rising inclined edges that are easily overcome when inserting transverse edges on the underside of the drawer.

Abstract
Description
Die Erfindung bezieht sich auf einen Schrank- oder Gestellkörper, insbesondere zur Aufnahme von Schubladen oder Schubfächern, umfassend eine Mehrzahl von einander gegenüberliegend angeordneten, flächenhaften Wandelementen sowie mindestens ein den Zwischenraum zweier Wandelemente übergreifendes und diese Wandelemente miteinander form- oder kraftschlüssig verbindendes Querglied, wobei an mindestens einer Flächenseite jeweils eines Wandelementes wenigstens ein Rastanschluss für das Querglied vorgesehen ist. Die Erfindung bezieht sich ferner auf einen Bauteilsatz für Schrank- oder Gestellkörper, insbesondere zur Aufnahme von Schubladen oder Schubfächern.The invention relates to a cabinet or frame body, in particular for receiving drawers or drawers, comprising a plurality of flat wall elements arranged opposite one another and at least one cross member that crosses the space between two wall elements and connects these wall elements to one another in a positive or non-positive manner at least one surface side of each wall element, at least one locking connection is provided for the cross member. The invention further relates to a set of components for cabinet or frame bodies, in particular for receiving drawers or drawers.
Ein Schrankköper der eingangs erwähnten Art ist bekannt aus der CH-PS .474235. Dort sind einander gegenüberliegende.Seitenwände des Schrankkörpers.durch Boden- und Deckenteile sowie Zwischenböden miteinander verbunden, wobei diese plattenförmigen Querelemente in Richtung parallel zur Ebene der Seitenwände formschlüssig an letzteren abgestützt sind. Damit ergibt sich zwar eine ausreichende Tragfähigkeit gegen vertikal wirkende Belastungen, jedoch keine Sicherung der Seitenwände gegen Kippen und damit gegen eine parallelogrammartige Verformung des gesamten Schrankkörpers. Hierfür sind bei der bekannten Konstruktion vielmehr besondere Eckverbindungen vorgesehen, welche die Vorder- und Hinterkanten der Seitenwände der plattenförmigen Querelemente in den Eckbereichen ihrer Stossstellen mit Klemmgliedern umgreifen. Dies bedingt nicht nur besonderen Herstellungsaufwand für die vergleichsweise kompliziert geformten Eckverbindungselemente, sondern macht auch eine Anpassung und besondere Formgebung der Seitenwände und Querelemente notwendig, wenn die allgemein gewünschte, versenkte und glattflächige Anordnung der Verbindungselemente erreicht werden soll.A cabinet body of the type mentioned is known from CH-PS .474235. There are opposite. Side walls of the cabinet body. Connected to one another by floor and ceiling parts and intermediate floors, these plate-shaped transverse elements being positively supported on the latter in the direction parallel to the plane of the side walls. Although this results in a sufficient load-bearing capacity against vertically acting loads, the side walls are not secured against tipping and thus against a parallelogram-like deformation of the entire cabinet body. For this are at the known construction rather special corner connections are provided, which encompass the front and rear edges of the side walls of the plate-shaped transverse elements in the corner regions of their joints with clamping members. This not only requires special manufacturing effort for the comparatively complicated shaped corner connecting elements, but also makes it necessary to adapt and shape the side walls and transverse elements if the generally desired, recessed and smooth surface arrangement of the connecting elements is to be achieved.
Aufgabe der Erfindung ist daher die Schaffung eines Schrankkörpers und eines entsprechenden Bauteilsatzes; bei denen eine einfache Konstruktion sowie vergleichsweise geringer Montageaufwand und eine formschlüssige Sicherung gegen Verformung des Schrankkörpers quer zu den Wandelementen erreichbar ist. Die erfindungsgemässe Lösung dieser Aufgabe kennzeichnet sich hinsichtlich des Schrankkörpers und des Bauteilsatzes durch die Merkmale der Ansprüche 1 bzw.24.The object of the invention is therefore to create a cabinet body and a corresponding set of components ; in which a simple construction and comparatively little installation effort and a positive locking against deformation of the cabinet body can be achieved transversely to the wall elements. The solution to this problem according to the invention is characterized in terms of the cabinet body and the component set by the features of claims 1 and 24, respectively.
Der danach vorgesehene Rastausschluss ermöglicht eine biegesteife Abstützung der Wandelemente gegeneinander, wobei die konvexen Rastelemente beispielsweise am Wandelement angeformt sind und als Kragarme wirken, die ihrerseits biegesteif mit den zugehörigen Querträgern verbunden sind. Mit besonderem Vorteil werden die Tragflächen der Rastelemente wenigstens annähernd rechtwinklig zur Ebene eines Wandelementes sowie zueinander paarweise entgegengesetzt orientiert angeordnet. Dadurch ergibt sich ein biegesteifer Rastanschluss, dessen Elemente sich leicht in die Querschnittshöhe des.Querträgers einfügen lassen. Damit wird der Nutzraumanteil verbessert. Vorzugsweise werden an einem Wandelement mehrere Querträger mit je einem Rastanschluss an beiden Enden vorgesehen. Grundsätzlich kommen jedoch auch Querträger grösserer Querschnittbreite in Betracht, z.B. plattenförmige, biegesteife Querträger, die einen grösseren Teil der Breite der beiderseitigen Wandelemente übergreifen und je mit mehreren Rastanschlüssen an beiden Seitenkanten versehen sind. Solche plattenförmigen, biegesteifen Querträger können insbesondere als Ablagefächer ohne Schubladen verwendet werden. Damit können Gestellkörper von einfachem Aufbau trotz grosser Fachzahl erhalten werden.The latching exclusion provided thereafter enables the wall elements to be supported against one another in a rigid manner, the convex latching elements being formed, for example, on the wall element and acting as cantilever arms which in turn are rigidly connected to the associated cross members. With particular advantage, the wings of the latching elements are arranged at least approximately at right angles to the plane of a wall element and in pairs opposite to one another. This results in a rigid locking connection, the elements of which can be easily inserted into the cross-sectional height of the cross member. This improves the proportion of usable space. Preferably, a plurality of cross members are provided on a wall element, each with a latching connection at both ends. Basically, however, cross beams with a larger cross-sectional width can also be considered, for example plate-shaped, rigid cross beams which overlap a larger part of the width of the wall elements on both sides and are each provided with a plurality of snap-in connections on both side edges. Such plate-shaped, rigid cross members can be used in particular as storage compartments without drawers. In this way, frame bodies of simple construction can be obtained despite the large number of compartments.
Von den jeweils einer Seitenkante eines solchen plattenförmigen Querträgers zugeordneten Rastanschlüssen braucht grundsätzlich nur einer biegesteif zu sein, und zwar gegebendenfalls sogar nur für eine der Seitenkanten, während die übrigen Rastanschlüsse nur als Verankerung des Querträgers gegen Zug- und Scherkrafte in bezug auf die Wandelemente wirken. Optimale Festigkeit und Formbeständigkeit des Schrankkörpers ergibt sich jedoch bei biegesteifer Ausbildung aller Rastanschlüsse.In principle, only one of the latching connections assigned to one side edge of such a plate-shaped crossmember needs to be rigid, and possibly even only for one of the side edges, while the other latching connections only act as anchoring of the crossmember against tensile and shear forces in relation to the wall elements. Optimal strength and dimensional stability of the cabinet body results from a rigid construction of all locking connections.
Nach einer Weiterbildung der Erfindung sind jeweils mindestens zwei Querträger mit entsprechnden Rastelementen an den Wandelementen auf einer parallel zu einer Schubladen- oder Schubfachebene verlaufenden Linie angeordnet und können gegebenenfalls unmittelbar als Schubladenauflage und -führung dienen. Dabei ist es allgemein von Vorteil, die Tragflächen der konvexen und konkaven Rastelemente wenigstens annähernd parallel zu der Schubladen- oder Schubfachebene anzuordnen. Durch diese Massnahme ergibt sich eine vergleichsweise geringe Höhenabmessung der Verbindungselemente und eine Verminderung des ungenutzten Schrankinnenraumes.According to a further development of the invention, at least two cross members with corresponding locking elements are arranged on the wall elements on a line running parallel to a drawer or drawer level and can optionally serve directly as a drawer support and guide. It is generally advantageous to arrange the wings of the convex and concave locking elements at least approximately parallel to the drawer or drawer level. This measure results in a comparatively small height dimension of the connecting elements and a reduction in the unused cabinet interior.
Eine wesentliche Weiterbildung des erfindungsgemässen Schrankkörpers kennzeichnet sich dadurch, dass die konvexen Rastelemente als Abschnitte eines sich parallel zur Schubladen- oder Schubfachebene erstreckenden, leistenförmigen Tragsteges ausgebildet sind. Dies vereinfacht nicht nur die Formgebung und damit die Herstellung der Tragstege, sondern ermöglicht auch ohne besonderen Aufwand das Ansetzen einer grösseren Anzahl von Querträgern an jeweils einem solchen Tragsteg, ohne dass für die einzelnen Anschlussstellen gesonderte Rastelemente zu bilden wären. Insbesondere empfiehlt sich in diesem Zusammenhang eine einstückige Anformung solcher als Versteifungsrippen ausgebildeten Tragstege an ein Wandelement, wobei sich der Tragsteg im Interesse der Versteifungswirkung und eines ausreichenden Abstandes der Anschlussstellen für die Querträger zweckmässig wenigstens über den überwiegenden Teil der Wandelementbreite erstreckt.An essential development of the cabinet body according to the invention is characterized in that the convex latching elements are designed as sections of a strip-shaped supporting web extending parallel to the drawer or drawer level. This not only simplifies the shape and thus the manufacture of the supporting webs, but also enables a large number of cross members to be attached to such a supporting web without any particular effort, without separate latching elements having to be formed for the individual connection points. In this context, it is particularly advisable to integrally form such support webs, which are designed as stiffening ribs, on a wall element, the support web being in the interest of the reinforcement effect and a sufficient distance between the connection points for the cross members expediently extends at least over the major part of the wall element width.
Die Verankerung der Querträger an den Wandelementen gegen Zugkräfte in Längsrichtung der Träger kann grundsätzlich kraftschlüssig, d.h. durch ausreichende Klemmung und Haftreibung zwischen den Tragflächen der konvexen und konkaven Rastelemente erreicht werden. Hierfür empfiehlt sich eine spitzwinklige Anordnung der jeweils zueinander entgegengesetzt orientierten Tragflächen der komplementären Rastelemente unter Bildung einer selbsthemmenden Keilverbindung innerhalb einer jeden Rastverbindung. Das Zusammensetzen einer solchen Verbindung kann auf einfache Weise durch Zusammenpressen vorgenommen werden, im allgemeinen von Hand ohne besondere Werkzeuge.The anchoring of the cross beams on the wall elements against tensile forces in the longitudinal direction of the beams can in principle be non-positive, i.e. can be achieved by sufficient clamping and static friction between the wings of the convex and concave locking elements. For this purpose, an acute-angled arrangement of the oppositely oriented wings of the complementary locking elements is recommended, forming a self-locking wedge connection within each locking connection. Such a connection can be assembled in a simple manner by pressing it together, generally by hand without special tools.
Andererseits kommt mit besonderem Vorteil für stärkere Beanspruchungen des Schrankkörpers eine formschlüssige Verankerung der Querträger an den Wandelementen in Betracht. Hierfür sieht eine Weiterbildung der Erfindung vor, dass wenigstens eines der konvexen Rastelemente eine Hinterschneidung für den quer zur Wandebene gerichteten Angriff eines am zugehörigen Querträger gebildeten Formschluss-Verriegelungselementes aufweist. Das Zusammensetzen gestaltet sich hierbei besonders einfach, weil die Klemmkraft und damit der beim Zusammensetzen der Rastverbindung zu überwindende Widerstand infolge entsprechend schwacher Bemessung der Keilwirkung gering gehalten werden kann. Gegebenenfalls können die zueinander entgegengesetzt orientierten Tragflächen der Rastelemente parallel angeordnet und damit im Interesse einer besonders leichten Montage ohne Keilwirkung ausgeführt werden.On the other hand, it is particularly advantageous for the cabinet body to be positively anchored to the cross members on the wall elements for greater stresses. For this purpose, a further development of the invention provides that at least one of the convex latching elements has an undercut for the attack of a form-locking locking element formed on the associated cross member at right angles to the wall plane. Assembling is particularly easy here because the clamping force and thus that of Assembling the snap-in connection resistance to be overcome can be kept low due to correspondingly weak dimensioning of the wedge effect. If necessary, the oppositely oriented wings of the latching elements can be arranged in parallel and thus be executed without wedging in the interest of particularly easy assembly.
Eine wesentliche Weiterbildung der Erfindung richtet sich auf die Unterbringung von Schubladen oder Schubfächern vergleichsweise geringer"Höhe innerhalb des Schrankkörpers. Solche niedrigen Schubelemente, die auch beispielsweise in Form von plattenförmigen Schubfächern ohne Seitenumrandung, etwa mit Aufnahmen für Kleinteile, in grösserer Anzahl übereinander vorgesehen werden, würden bei der Lagerung auf biegesteif ausgebildeten Querträgern vergleichsweise grossen Querschnitts einen vergleichsweise grossen Gesamtquerschnitt beänsprucht. und damit einen unerwünschten Verlust an nutzbarem Schrankraum mit sich bringen. Die Weiterbildung der Erfindung sieht daher - im allgemeinen zusätzlich zu mindestens einem biegesteifen Querträger - wenigstens ein Querglied vor, das in seinem Mittelbereich elastisch-biegeweich ausgebildet und an zwei zueinander entgegengesetzten Endabschnitten durch Rastanschlüsse mit den beiderseitigen Wandelementen des Schrankkörpers verbunden ist. Diese biegeweiche Ausbildung ermöglicht eine sehr geringe Querschnittshöhe und damit einen geringen zusätzlichen Platzbedarf, wobei die Lagerung und Abstützung der Schubfächer unmittelbar an den durch Rastanschlüsse mit den Wandelementen verbundenen Endabschnitten der Querglieder erfolgt. Hier macht sich die Biegeweichheit der Querglieder für die Aufnahme des Schubfachgewichtes nicht störend bemerkbar. Die entsprechende Entlastung des Mittelabschnittes und damit des gesamten Quergliedes von Biegemomenten durch die Lastaufnahme ergibt sich selbsttätig durch das Zusammenwirken der in Vertikalrichtung steifen Rastanschlüsse mit der vertikalen Nachgiebigkeit des mittleren Quergliedabschnittes. Die elastisch-biegeweiche Ausbildung der Querglieder ermöglicht in besonders vorteilhafter Weise die Montage der Querglieder in einem bereits zusammengesetzten Schrankkörper. Hierzu wird ein Querglied von Hand aus seiner ebenen Form ausgebogen und damit in seiner Querabmessung verkürzt, so dass es bequem in die Breit des Schrankinnern eingeführt werden kann. Auf einer Seite lassen sich dann die Endabschnitte des Quergliedes leicht in die zugehörigen Wandelementausnehmungen der Rastanschlüsse einführen, worauf das Einrasten in die Ausnehmungen des gegenüberliegenden Wandelementes durch Freigabe der elastischen Verformung und Rückkehr in die ebene Form des Quergliedes erfolgt. Die entsprechende Biegeweichheit lässt sich besonders einfach durch Verminderung der tragenden Querschnittslänge im Mittelbereich des Plattenkörpers eines solchen Quergliedes erreichen. Im übrigen ist im allgemeinen für diese Montageart eine Biegeweichheit bzw. Nachgiebigkeit gegen Querkräfte ausreichend, die durchaus mit einer Tragfunktion für die Aufnahme leichterer, abzulegender Gegenstände vereinbar ist. Die erwähnten Querglieder können also gegebenenfalls selbst als Aufnahmefächer ohne eingesetzte Schubladen oder Schubfächer ausgebildet werden.An essential development of the invention is aimed at accommodating drawers or drawers of comparatively low height within the cabinet body. Such low push elements, which are also provided in large numbers one above the other, for example in the form of plate-shaped drawers without side borders, for example with receptacles for small parts, would require a comparatively large overall cross-section when stored on rigid cross members of comparatively large cross-section and thus result in an undesirable loss of usable cabinet space. The development of the invention therefore provides - in general in addition to at least one rigid cross-member - at least one cross member, which is designed to be elastic and flexible in its central region and is connected at two opposite end sections by snap-in connections to the wall elements of the cabinet body on both sides Formation enables a very low cross-sectional height and thus a small additional space requirement, whereby the storage and support of the drawers takes place directly at the end sections of the cross members connected to the wall elements by snap connections. Here, the softness of the transverse links does not have a disturbing effect on the weight of the drawer. The corresponding relief of the central section and thus of the entire cross member from bending moments due to the load absorption results automatically from the interaction of the vertically rigid locking connections with the vertical flexibility of the central cross member section. The elastic-flexible design of the cross members enables the cross members to be mounted in an already assembled cabinet body in a particularly advantageous manner. For this purpose, a cross member is bent out of its flat shape by hand and thus shortened in its transverse dimension, so that it can be easily inserted into the width of the cabinet interior. On one side, the end sections of the cross member can then be easily inserted into the associated wall element recesses of the latching connections, whereupon the engagement into the recesses of the opposite wall element takes place by releasing the elastic deformation and returning to the flat shape of the cross member. The corresponding flexural softness can be achieved particularly simply by reducing the load-bearing cross-sectional length in the central region of the plate body of such a cross member. For the rest, a softness or flexibility against transverse forces is generally sufficient for this type of installation, which is quite compatible with a carrying function for the inclusion of lighter objects to be put down. The cross members mentioned can thus, if appropriate, be designed as receiving compartments without inserted drawers or drawers.
Eine andere wesentliche Weiterbildung der Erfindung sieht bei einem Schrank- oder Gestellkörper der vorliegenden Art wenigstens ein in zwei zueinander entgegengesetzten Richtungen offenes Aufnahmefach vor, welches durch mindestens einen biegesteifen Querträger und/oder mindestens ein elastisch-biegeweiches Querglied in Verbindung mit beiderseitigen Wandelementen gebildet ist. Ein solches, in entgegengesetzten Richtungen offenes Aufnahmefach bzw. mehrere solcher Fächer ermöglichen eine beliebige Benutzung und Bedienung des Schrankes oder Gestells von beiden entgegengesetzten Stirnseiten aus. Dabei können diese Fächer für eine beiderseits zugängliche Ablage oder für das Durchreichen von Gegenständen, etwa Schriftstücken, zwischen den Stirnseiten des Schrankes oder Gestells ausgenutzt werden. Eine solche Verwendung erweist sich insbesondere bei umfangreichen Schrank- oder Gestellanordnungen, etwa von Schrank- oder Gestellwänden, zwischen zwei einander gegenüberliegenden Arbeitsplätzen als nützlich. Im übrigen kann ein solches, beiderseits offenes Aufnahmefach wahlweise auch für das Einsetzen von zueinander entgegengesetzt orientierten Halbschubladen verwendet werden. Ebenso besteht ein wesentlicher Vorteil darin, dass die bezüglich der entgegengesetzten Stirnseiten symmetrische Ausbildung des Schrank- oder Gestellkörpers einen beliebigen Schubladeneinsatz mit Bedienung von der einen oder anderen Seite ermöglicht. Beispielsweise kann also der unterschiedliche Bedarf an Schrank- oder Gestellraum an zwei einander gegenüberliegend angeordneten Arbeitsplätzen flexibel berücksichtigt werden. Insgesamt ergibt sich also eine wesentliche Erweiterung des Anwendungsbereiches und eine Verbesserung der Anpassungsfähigkeit hinsichtlich unterschiedlicher Einsatzbedingungen.Another essential further development of the invention provides for a cabinet or frame body of the present type at least one receiving compartment which is open in two opposite directions and which is formed by at least one rigid cross member and / or at least one elastic-flexible cross member in connection with wall elements on both sides. Such a receiving compartment, which is open in opposite directions, or a plurality of such compartments enable the cabinet or frame to be used and operated in any manner from both opposite end faces. These compartments can be used for storage accessible from both sides or for passing objects, such as documents, between the front sides of the cabinet or frame. Such use proves to be particularly useful in the case of extensive cupboard or frame arrangements, for example of cupboard or frame walls, between two mutually opposite workplaces. Moreover, such a storage compartment, which is open on both sides, can optionally also be used for inserting half-drawers oriented in opposite directions. There is also a significant advantage in that the design of the cabinet or frame body, which is symmetrical with respect to the opposite end faces, provides an arbitrary thrust Shelf use with operation from one side or the other enables. For example, the different requirements for cupboard or rack space at two workplaces located opposite one another can be flexibly taken into account. Overall, this results in a significant expansion of the area of application and an improvement in adaptability with regard to different operating conditions.
Der zum Erfindungsgegenstand gehörende Bauteilsatz für Schrankkörper besteht infolge seiner Kennzeichnungsmerkmale nur aus Flachkörpern von vergleichsweise geringer Querschnittshöhe, nämlich den flächenhaften Wandelementen sowie ebensolchen Quergliedern und Querträgern. Dies bietet den besonderen Vorteil einer Zusammenlegbarkeit und Verpackung mit geringem Platzbedarf in Form eines kompakten Flachkörpers.The set of components for cabinet bodies belonging to the subject of the invention, due to its identification features, consists only of flat bodies of comparatively small cross-sectional height, namely the flat wall elements and the same cross members and cross members. This offers the particular advantage of collapsibility and packaging with a small footprint in the form of a compact flat body.

Nach Fig. 1 und 2 besteht der Schrankkörper aus beiderseitigen Wandelementen WE mit Querträgern QT, die an ihren Enden mit Tragstegen TS der Wandelemente durch Rastanschlüsse RS verbünden sind. Im Beispielsfall sind die Querträger in der aus Fig. 2 ersichtlichen Weise auf gleicher Höhe bezüglich der Schubladenebenen E-E sowei zueinander parallel und mit gegenseitigem Abstand innerhalb des Schrankinnenraumes angeordnet, so dass sich ein steife und hochfeste Abstützung der beiden Wandelemente gegeneinander ergibt.1 and 2, the cabinet body consists of wall elements WE on both sides with cross members QT, which ver at their ends with support webs TS of the wall elements by snap connections RS are covenants. In the case of the example, the cross members are arranged in the manner shown in FIG. 2 at the same height with respect to the drawer levels EE and parallel to one another and at a mutual distance within the interior of the cabinet, so that there is a rigid and high-strength support of the two wall elements against one another.
Zwischen den übereinanderliegenden Querträgerpaaren sowie an der Oberseite des obersten Querträgerpaares ist je ein Aufnahmefach FC für eine Schublade gebildet. Diese Aufnahmefächer sind an den zueinander entgegengesetzt orientierten Stirnseiten ST offen ausgebildet und weisen durchgehend die gleiche lichte Querschnittshöhe auf. Die Schubladen können also beliebig von beiden Seiten eingeführt werden. Insgesamt ist der Schrankkörper darüberhinaus bezüglich der entgegengesetzten Stirnseiten ST symmetrisch ausgebildet, so dass keine Einschränkung hinsichtlich der Anordnung der Bedienungsseite der Schubladen bestehen. Ebenso ist der Einsatz von zueinander entgegengesetzt orientierten Halbschubladen möglich, was in den Zeichnungen nicht näher dargestellt ist. Mit Hilfe noch zu erläuternder, plattenförmiger Querglieder oder auch mit Hilfe der bereits erwähnten, plattenförmigen und biegesteif ausgebildeten Querträger können die Aufnahmefächer FC mit geschlossenen Bodenflächen versehen werden. Damit ergeben sich insbesondere auch für Kleingegenstände brauchbare Ablagefächer, die wahlweise ebenso für den Einsatz von Schubladen verwendbar sind.A receiving compartment FC for a drawer is formed between the pairs of crossbeams on top of each other and on the top of the top pair of crossbeams. These compartments are open on the mutually oppositely oriented end faces ST and have the same clear cross-sectional height throughout. The drawers can therefore be inserted from either side. Overall, the cabinet body is also symmetrical with respect to the opposite end faces ST, so that there are no restrictions with regard to the arrangement of the operating side of the drawers. It is also possible to use half-drawers oriented in opposite directions, which is not shown in the drawings. With the help of plate-shaped cross members to be explained or with the aid of the plate-shaped and rigid cross beams mentioned above, the receiving compartments FC can be provided with closed bottom surfaces. This results in storage compartments that can also be used for small items, which can optionally also be used for the use of drawers.
Auf der untersten Querträgerebene ist in Fig. 1 und 2 schematisch eine Schublade S mit einer Höhe entsprechend dem Abstand über- - einanderliegender Querträger und Tragstege angedeutet, die sich mit ihren nach unten über den Schubladenboden vorstehenden Seitenkanten auf den Tragstegen TS abstützt. Damit ergibt sich eine sichere Führung der Schublade auch in vergleichsweise weit ausgezogener Lage.1 and 2, a drawer S with a height corresponding to the distance one above the other - crossmembers and supporting webs lying one above the other, which is supported on the supporting webs TS with their side edges projecting downward over the bottom of the drawer, is schematically indicated in FIGS. This results in a safe guidance of the drawer even in a relatively extended position.
Der untere Abschluss des Schrankkörpers ist allein durch die Querträger gebildet, während die Oberseite durch einen benachbarten, aufgesetzten Schrankkörper (in Fig. -1 bis 3 nur teilweise angedeutet) abgeschlossen ist. Hierzu ist an der Oberkante OK der Wandelemente ein quer zur Wandebene und zur Innenseite des Schrankkörpers hinauskragender Auflagesteg AS einstückig angeformt und mit einem leistenförmigen, nach oben vorstehenden ersten Anschlagelement ASO für die Lagesicherung der aufeinander gesetzten Schrankkörper gegeneinander versehen. An der Unterseite des oberen Schrankkörpers und infolge der übereinstimmenden Ausbildung auch an der entsprechenden Stelle des unteren Schrankkörpers ist ein komplementäres zweites Anschlagelement ASU vorgesehen, und zwar in einfacher Weise als Innenflächenabschnitt des betreffenden Tragsteges TS. Je ein Paar solcher ersten und zweiten Anschlagelemente bildet in der aus Fig. 1 und 2 ersichtlichen Weise eine in zwei zueinander rechtwinkligen Horizontalrichtungen formschlüssige Anschlagverbindung, so dass die beiden Schrankkörper eine allseitige Lagesicherung aufweisen. Es versteht sich, dass für Einzelaufstellung eines Schrankkörpers eine geeignete, etwa mit Anschlagelementen ASU versehene Abschlussplatte für die Oberseite des Schrankkörpers vorgesehen werden kann (nicht dargestellt).The lower end of the cabinet body is formed solely by the cross member, while the top is closed by an adjacent, mounted cabinet body (only partially indicated in Fig. -1 to 3). For this purpose, a support web AS projecting transversely to the wall level and to the inside of the cabinet body is integrally formed on the upper edge OK of the wall elements and provided with a strip-shaped, upwardly projecting first stop element ASO for securing the position of the stacked cabinet body against one another. A complementary second stop element ASU is provided on the underside of the upper cabinet body and, as a result of the matching design, also at the corresponding point on the lower cabinet body, in a simple manner as an inner surface section of the supporting web TS in question. A pair of such first and second stop elements each form, in the manner shown in FIGS. 1 and 2, a positive stop connection in two horizontal directions that are perpendicular to one another, so that the two cabinet bodies secure the position on all sides exhibit. It goes without saying that a suitable end plate (for example, provided with stop elements AS U) for the top of the cabinet body can be provided for the individual installation of a cabinet body (not shown).
Eine entsprechende Anschlussmöglichkeit und gegenseitige Lagesicherung ergibt sich auch für seitlich benachbart angeordnete Schrankkörper. Hierzu sind nach Fig. 1 an der zu den Tragstegen TS entgegengesetzten Oberfläche der Wandelemente WE jeweils im Bereich der einzelnen Tragstege nutenförmige Ausnehmungen NT eingeformt. Letztere erstrecken sich innerhalb der Querschnittshöhe und der Längenausdehnung der Tragstege, so dass letztere U-profilartige Hohlkörper mit entsprechender Querschnittshöhe und grosser Biegefestigkeit in ihrer Verbindung mit dem Plattenkörper des Wandelementes darstellen. In die nutenförmigen Ausnehmungen NT sind in der aus Fig. 4 ersichtlichen Weise Lagesicherungselemente LS eingesetzt, die in entsprechende Ausnehmungen-der Nachbar-Schrankkörper eingreifen. Die Ausnehmungen NT sind im Interesse der Steifheit des Wandelement-Plattenkörpers mit verteilt angeordneten Querstegen QS versehen. Die Ausnehmungen haben im übricen bei einer Herstellung der Wandelemente als Kunststoff-Pressteile oder -Spritzteile den Vorteil, dass Materialanhäufungen mit der Gefahr entsprechender Erkaltungsschrumpfung und Oberflächenbeeinträchtigung entfallen.A corresponding connection option and mutual securing of position also results for cabinet bodies which are arranged laterally adjacent. For this purpose, according to FIG. 1, groove-shaped recesses NT are formed on the surface of the wall elements WE opposite the support webs TS in the region of the individual support webs. The latter extend within the cross-sectional height and the length of the supporting webs, so that the latter represent U-shaped hollow bodies with a corresponding cross-sectional height and great bending strength in their connection with the plate body of the wall element. Position securing elements LS are inserted into the groove-shaped recesses NT, as shown in FIG. 4, which engage in corresponding recesses — the neighboring cabinet body. The recesses NT are provided with distributed crosspieces QS in the interest of the rigidity of the wall element plate body. The recesses also have the advantage when producing the wall elements as plastic pressed parts or molded parts that material accumulations with the risk of corresponding cooling shrinkage and surface impairment are eliminated.
Wie aus Fig. 1 und 3 ersichtlich ist, haben die Tragstege TS infolge der erwähnten, U-förmigen Profilierung einen-von der. Oberfläche des zugehörigen Wandelementes nach aussen, d.h. zum Schrankinnenraum hin, abnehmende Querschnittshöhe und bilden im Bereich der auskragenden Längskante einen plattenförmigen Abschnitt PL, der sich über den überwiegenden Teil der Steglänge erstreckt (siehe auch Fig. 4). Dieser plattenförmige Abschnitt eignet sich ohne weiteres auf seiner gesamten Länge für die Punktion eines konvexen Rastelementes für den Anschluss von Querträgern. Im Beispielfall sind nur die beiderseitigen Endabschnitte des plattenförmigen Stegabschnitts PL als konvexe Rastelemente REX für den Eingriff in entsprechende konkave Rastelemente REV an den Querträgerenden vorgesehen.As can be seen from FIGS. 1 and 3, the support webs TS have one of the following as a result of the U-shaped profiling mentioned. Surface of the associated wall element to the outside, i.e. towards the interior of the cabinet, decreasing cross-sectional height and form a plate-shaped section PL in the region of the projecting longitudinal edge, which extends over the major part of the web length (see also FIG. 4). The entire length of this plate-shaped section is suitable for puncturing a convex locking element for connecting cross beams. In the example, only the end portions of the plate-shaped web portion PL on both sides are provided as convex locking elements REX for engaging corresponding concave locking elements REV on the cross beam ends.
Fig. 5 zeigt die Möglichkeit, ein Wandelement WE1 an beiden zueinander entgegengesetzten Flächenseiten mit leistenförmigen Tragstegen TS zu versehen. Die wiedergegebene Teil-Vorderansicht zeigt einen Bereich des Wandelementes mit auf gleicher Höhe angeordneten, zueinander entgegengesetz orientierten Tragstegen, deren Querschnittsform im Vergleich zu den Tragstegen TS der vorangehend beschriebenen Ausführungsform vereinfacht ist und im wesentlichen nur durch einen plattenförmigen Stegabschnitt PL gebildet ist. Am vorderen und hinteren Ende dieses Stegabschnittes sind wiederum konvexe Rastelemente REX wie bei der vorangehenden Ausführung angeformt. In beiden Ausführungen sind im Bereich der konvexen Rastelemente REX Versteifungsrippen QV an den Wandkörper einerseits und an den Stegabschnitt PL andererseits angeformt. Hierdurch ergibt sich eine erhöhte Biegefestigkeit des Stegabschnitts PL und der Rastelemente REX. Dies ist besonders für die Ausführungen nach Fig.5 wesentlich, weil der Tragsteg TS1 zwecks Geringhaltung von Materialanhäufungen als vergleichsweise schmale und dünne Leiste ausgebildet ist, die an sich gewisse Biegefestigkeit hat. Als Auflage und Führung für die Schubladen im Bereich zwischen den Querträgern QT kann auch noch ein vergleichsweise schmaler Leistenansatz P vorgesehen werden. Mit den beiderseitigen Tragstegen an einem Wandelement lassen sich batterieförmige Mehrfach-Schrankkörper auf einfache Weise zusammensetzen.FIG. 5 shows the possibility of providing a wall element WE 1 on both opposite surface sides with strip-shaped support webs TS. The partial front view shown shows an area of the wall element with supporting webs arranged at the same height and oriented opposite to one another, the cross-sectional shape of which is simplified compared to the supporting webs TS of the previously described embodiment and is essentially formed only by a plate-shaped web section PL. At the front and rear end of this web section, convex locking elements REX are in turn molded as in the previous embodiment. In both versions, in the area of the convex locking elements REX, stiffening ribs QV are on the wall body on the one hand and on the web section PL molded on the other. This results in an increased bending strength of the web section PL and the locking elements REX. This is particularly important for the designs according to FIG. 5, because the supporting web TS1 is designed as a comparatively narrow and thin strip, in order to keep material accumulations to a minimum, which in itself has a certain bending strength. A comparatively narrow strip attachment P can also be provided as a support and guide for the drawers in the area between the cross members QT. With the double-sided supporting bars on a wall element, battery-shaped multiple cabinet bodies can be easily assembled.
Die Querträger sind in der aus Fig. 6 und 7 ersichtlichen Weise als U-Profilkörper mit Versteifungs-Querrippen V ausgebildet, wodurch die Biegefestigkeit und Biegesteifheit erhöht wird. Die Endabschnitte der Profilinnenräume bilden die Querträger in der aus Fig. 4 ersichtlichen Weise mit ihren offenen Profilseiten zum Schrankinnenraum hin auf die konvexen Rastelemente REX aufgedrückt. Infolge einer (nicht zeichnerisch dargestellten) spitzwinkligen Anordnung der zueinander entgegengesetzten orientierten Tragflächen TRX bzw. TRV der Rastelemente REX bzw. REV ergibt sich eine selbsthemmende Klemmwirkung der Rastelemente, wodurch eine sichere Keilverbindung zwischen den Querträgern und den Wandelementen geschaffen ist. Es versteht sich, dass die Tragflächenpaare jeweils entgegengesetzt zur Eintreffrichtung der Querträger spitzwinklig zusammenlaufen, in bezug auf Fig. 4 also jeweils in Richtung vom Schrankinnenraum nach aussen und parallel zur Ebene der Wandelemente WE.The cross beams are formed in the manner shown in FIGS. 6 and 7 as a U-profile body with stiffening transverse ribs V, which increases the bending strength and bending stiffness. The end sections of the profile interiors form the cross members in the manner shown in FIG. 4 with their open profile sides pressed toward the cabinet interior onto the convex locking elements REX. As a result of an acute-angled arrangement (not shown in the drawing) of the oppositely oriented wing surfaces TRX and TRV of the latching elements REX and REV, the latching elements have a self-locking effect, thereby creating a secure wedge connection between the cross members and the wall elements. It goes without saying that the wing pairs each converge at an acute angle opposite to the direction of arrival of the crossbeams, that is to say with respect to FIG. 4 in the direction from the interior of the cabinet to the outside and parallel to the plane of the wall elements WE.
Die Rastelemente REX sind dabei gemäss Fig. 2 auf einer parallel zur Schubladenebene E-E verlaufenden Linie X-X angeordnet, so dass die Querträger ebenfalls auf gleicher Höhe bezüglich der Schubladenebene angeordnet sind und sich daher in die gesamte Tragfläche für die Abstützung der zugehörigen Schublade einfügen. Die Verwendung von Abschnitten des plattenförmigen Abschnitts PL eines jeden Tragsteges TS als Rastelemente hat zur Folge, dass letztere ebenfalls parallel zur Schubladenebene angeordnet sind und daher eine vergleichsweise grosse Breitenausdehnung haben können. Dadurch ergibt sich trotz vergleichsweise geringer Querschnitthöhe der Rastelemente REX eine ausreichende Biegefestigkeit und Biegesteifheit.2, the locking elements REX are arranged on a line X-X running parallel to the drawer plane E-E, so that the cross members are also arranged at the same height with respect to the drawer plane and therefore fit into the entire wing for supporting the associated drawer. The use of sections of the plate-shaped section PL of each support web TS as locking elements has the consequence that the latter are also arranged parallel to the drawer plane and can therefore have a comparatively large width. Despite the comparatively small cross-sectional height of the REX locking elements, this results in sufficient bending strength and bending stiffness.
In der Beispielsausführung ist darüberhinaus eine formschlüssige Verankerung der Querträger an den Wandelementen in bezug auf Kräfte längs zur Trägerachse vorgesehen. Hierzu sind an den konvexen Rastelementen REX Hinterschneidungen HS gebildet, in die Formschluss-Verriegelungselemente VR an den Enden der Querträger eingreifen. Diese Verriegelungselemente sind einfach als Abschlusswände des U-Profils der Querträger ausgebildet und rufen daher keinen zusätzlichen Formgebungsaufwand hervor.In the example embodiment, there is also a positive anchoring of the cross members on the wall elements with respect to forces along the support axis. For this purpose, undercuts HS are formed on the convex locking elements REX, into which form-locking locking elements VR engage at the ends of the cross members. These locking elements are simply designed as end walls of the U-profile of the cross member and therefore do not cause any additional shaping effort.
In den Fig. lbis3 ist die Anordnung eines Zwischenfaches ZF innerhalb des Höhenabstandes zweier Querträger QT mit zugehörigen Tragstegen TS in Form eines vergleichsweise dünnwandigen, plattenförmigen Quergliedes QR angedeutet. Für die Verbindung dieser Querglieder mit den Wandelementen sind Rastanschlüsse RA vorgesehen, die aus abschnittsweise vorspringenden-Kantenabschnitten KT-des Quergliedes einerseits und entsprechenden Ausnehmungen AN an der Innenseite der Wandelemente andererseits bestehen. Die Montage eines solchen biegeweichen Zwischenbodens in dem zusammengesetzten Schrankkörper ist bereits einleitend erläutert worden. Fig. 7 zeigt eine einfache Möglichkeit zur Einstellung der geeigneten Biegeweichheit, indem nämlich die Querschnittslänge (in Einschubrichtung gemessen) im mittleren Bereich des Plattenkörpers gegenüber den Kantenabschnitten vermindert ist. Anstelle der vorliegenden Kontureinschnürung kann gegebenenfalls eine entsprechende Aussparung treten. Die im Beispiel angedeutete Einschnürung der Tiefenabmessung des Plattenkörper im Bereich seiner Mittelachse Y-Y ergibt jedoch den wesentlichen Vorteil, dass infolge der hierdurch gebildeten, zur Achse Y-Y bzw. zur Schubladen-Bewegungsrichtung schräg verlaufenden Abschnitte der Vorderkante VK kein Anstossen der Schublade an einer etwa nach oben und unten vorstehenden Querkante des Plattenkörpers auftreten kann. Bei etwa vorkommender Verspannung des Schrankkörpers muss wegen der Biegeweichheit des Plattenkörpers u. U. mit einer geringfügigen Durchbiegung nach oben und und gerechnet werden, die ein solches Anstossen hervorrufen könnte. Die vorliegende Kontur bildet dann jedoch schwach ansteigend geneigte Auflaufkanten, die beim Einschieben auch von Querkanten an der Schubladenunterseite ohne weiteres überwunden werden. Entsprechendes gilt für die Hinterkante HK in Bezug auf die Ausziehbewegung der Schublade sowie auch für die Einschiebebewegung im Fall von in ein Aufnahmefach zueinander gegenseitig eingesetzten Halbschubladen.The arrangement of an intermediate compartment ZF within the vertical distance between two cross members QT with associated supporting webs TS in the form of a comparatively thin-walled, plate-shaped cross member QR is indicated in FIGS. For the Connection of these cross members to the wall elements are provided with locking connections RA, which consist of section-projecting edge sections KT-of the cross member on the one hand and corresponding recesses AN on the inside of the wall elements on the other hand. The assembly of such a flexible intermediate floor in the assembled cabinet body has already been explained in the introduction. FIG. 7 shows a simple way of setting the suitable bending softness, namely by reducing the cross-sectional length (measured in the direction of insertion) in the central region of the plate body compared to the edge sections. Instead of the existing constriction of the contours, a corresponding recess can optionally be used. The constriction of the depth dimension of the plate body in the region of its central axis YY indicated in the example, however, gives the essential advantage that, as a result of the sections of the front edge VK which run obliquely to the axis YY or the direction of movement of the drawer, the drawer does not hit an approximately upward side and the above transverse edge of the plate body can occur. If there is any tension in the cabinet body, the panel body must be flexible due to the flexibility of the panel. U. and a slight deflection may be expected and that could cause such a nudge. The present contour then, however, forms slightly rising inclined edges that are easily overcome when inserting transverse edges on the underside of the drawer. The same applies to the rear edge HK with respect to the pull-out movement of the drawer and also for the insertion movement in the case of half-drawers mutually inserted in a storage compartment.
