Description

The invention relates to a cabinet drawer, in particular a high cabinet drawer, with a arranged in an interior of a cabinet body, movable extension frame with a substantially vertically oriented support column which is connected to a lower frame frame, which is guided in the course of cabinet removal movement in a cabinet body guide and movable at the at least one tray or the like. Cabinet furnishings can be supported.

Conventional cabinet drawer have a substantially rectangular frame forming extension frame with two spaced apart vertical columns, wherein on the front vertical column to secure a furniture front and the rear vertical support column is provided with such a distance to the front support column, so that the depth of a cabinet for on the vertical columns to be fastened trays or the like. Cabinet items is available. In their foot areas and their head areas, the vertical support columns are interconnected by cross beams, which are guided in upper and lower cabinet body guides. This rollers can be used, but also telescopic elements. For attaching trays, for example, hooks are provided at intervals to each other on the vertical support columns.

The disadvantage is that for holding the shelves or the like. Cabinet furniture items are each provided two vertical support columns. In addition, the rear vertical column affects the maximum possible utilization of a cabinet depth. The upper cross bar, which connects the vertical column with each other and provides the upper guide of the extension frame, hinders beyond the useable room height of a cabinet and also affects the overall visual impression of the cabinet drawer.

From the DE 197 15 066 C2 is a cabinet drawer for tall cabinets of the aforementioned type, in which a vertical single column supports trays. To attach the trays to the vertical single column mounting rods are provided which are to be inserted into corresponding holes in the vertical single column, after which the mounting rods pass through the single vertical column and protrude on both sides for the purpose of supporting the trays out of this. This type of attachment of the trays on the vertical single column is relatively expensive and requires an accurate insertion of the mounting rods in the hole recesses. In addition, the hole recesses pierce the vertical single column, so that their capacity limits are set. In addition, shelves can only be provided according to the grid dimension of the hole recesses on the vertical column. A disadvantage, moreover, is that the vertical recess column is not only weakened by the hole recesses in total stress. Rather, such a vertical single column tends despite their advantages of being able to optimally utilize the cabinet depth with the shelves, they tend to lean under weight loads. If such a vertical column still carries a furniture front, this generally leads to the fact that when closing the cabinet drawer, the upper part of the furniture front to the cabinet body and thus restricts the cabinet drawer closing movement, although the lower portion of the furniture front is not yet applied to the cabinet body, which There is an unsightly gap formation due to the not completely closed cabinet drawer.

From the DE 198 4B 778 A1 is a pull-out for high cabinets with a fixed furniture rail with a U-shaped cross-sectional configuration is known, in which the upper longitudinal edges of the lateral, interconnected by a web cheeks are directed against the vertical longitudinal center plane of the extension guide to form raceways. In the front region of the furniture rail and on the inner sides of the cheeks pairs of support rollers are freely rotatably mounted, the upper support point is above the serving as raceways longitudinal edges of the furniture rail. Furthermore, a drawer rail with a U-shaped cross-sectional shape is provided with outwardly directed flanges and rear, paired rollers whose diameter corresponds to the inner height between the web and serving as raceways edges of the furniture rail. The upper support point of the support rollers for the flanges is higher by a small amount than the rear, located in the region of the rollers section of the flange of the slide rail. When the pull-out guide is retracted, the flange has a rearward inclination in its longitudinal direction, with the result that the in the operation of the puller leading pull-out rail is raised, the extent of this increase is predetermined by the size of the height difference and adjustable. This has the consequence that regardless of the load of the puller, the inclination is always performed during a pull-out movement, which can lead to heavy load this device in the closed state also has a gap, since the individually different load can not be adjusted currently ,

It is therefore an object of the present invention to improve a cabinet drawer of the type mentioned that even with the provision of only a vertical single column with loaded shelves or the like. Furnishings the cabinet drawer is close.

To solve this problem, the cabinet drawer of the type mentioned is characterized by the features specified in claim 1.

This is a cabinet drawer created in which even with loaded trays or the like. Cupboard furniture even with a slightly under this weight load, but otherwise substantially vertically aligned Einzelvertikalsäule a closing movement with the adapted to the support column furniture front or the like. Without a lower gap safely accomplish by this gap can be compensated automatically by the positional adjustment of the extension frame profile depending on the inclination of the support column. This ensures that an upper and a lower area of the furniture front during the closing process at the front edges of a cabinet body come into concern, although the individual vertical support column is not aligned 100% vertically due to the corresponding weight loads.

For automatic position adjustment of the substantially vertically oriented single support column, a resilient element is provided, which exerts a reaction force on the lower region of the support column in order to counteract the weight force such a reaction force - and aligned with the cabinet body during the closing movement - to compensate for any inclination of the single support column due to a weight load to the cabinet body inside out by compliance of the elastic element. For this purpose, as an elastic element, e.g. a leaf spring or a coil spring may be provided, but also a rubber element or the like. Elastic element, which are capable of a compliance and thus to an automatic position adjustment. It is preferably provided that the extension frame profile is placed within the cabinet body guide in an inclined position to perform the appropriate positional adjustment.

Preferred dimensions, the trays or the like. Cabinet items height-adjustable supported on the support column and lockable via a connection connector in different height positions on the support column. This allows the user to individually customize the appropriate shelves for the storage requirements required. The shelves are aligned to the cabinet body interior and on the front vertical single support column, which in turn also still wearing the furniture front, supported. For this purpose, the support column may be provided with a slot-shaped guide, in which the tray or the like. Barrier device object engages with the connection connector. As a result, the tray or the cabinet unit object is to be locked or clamped by the connection connector with the support column, in order to fix the tray exactly in position in a final assembly position. Special fasteners that are introduced, for example, as in the prior art in special hole recesses are thus unnecessary and thus can no longer weaken the support column in the areas where the corresponding weight moments are to take. Rather, the tray can be attached directly to the support column by means of the connection connector via a clamping, clamping or latching part.

Thus, a cabinet drawer is provided in which the cabinet item is locked by the terminal connector to the support column, e.g. is clamped so as to determine the tray exactly in a final assembly position. Special fasteners, which are to be introduced, for example, as in the prior art in particular hole recesses are therefore unnecessary. Rather, the tray can be attached directly to the support column by means of the connection connector via a clamping, clamping or latching part.

Particularly preferred is a cabinet drawer, which has a single support column, wherein the single support column has a guide in turn, in which the tray is slidably guided. The tray can be fixed in height to the single support column via the connection connector by eg clamping at any point become. For this purpose, the connection connector may be formed as a clamping part or have a corresponding clamping or clamping part, for example, equipped with a lever eccentric. A clamping part, which is clamped, for example, to undercuts of a slot-shaped guide in the single support column, can be solved by loosening the clamping element. Thereafter, a tray or the like can be moved along the guide. If the tray is brought to the desired location, the connection connector, for example by means of the eccentric lever, can be clamped to the single support column, after which the tray is held immovably and securely on the single support column. Thus, in a very simple manner and without tools from the end user, the tray or the like furnishings in height desired by him be attached to the single support column.

A guide can be designed so that heavy-duty shelves and the like engage in the support column. Particularly preferred is when interlocking parts, such as those of the slot guide and those of the connection connector are designed such that the tray so suspended from the single support column that it is supported under its own weight in a pre-assembly of the support column, if it is not easily raised , After gently lifting it can be moved up and down along the guide.

The single support column is preferably arranged in the front region of the cabinet drawer, so that the guide has in the single support column to the cabinet body interior or to the rear wall of the cabinet body. Thus, without the provision of a rear vertical support column, the shelves and the like cabinet furnishings are mounted, so that the cabinet space is optimally exploited by the cabinet depth. At the front, a furniture front can be attached to the single support column, so that the drawer, including the furniture front, can be pulled out of the cabinet, eg translatorily. The single support column is guided in cabinet carcass guides, it being preferred that an upper cabinet carcass guide relative to the cabinet height is offset so far down a connection provided on the support column that the cabinet drawer in its storage position within the cabinet body designed free of extension rack parts upper rack space Has. This not only has a positive effect on the appearance of the cabinet drawer, but also creates a sufficient unimpaired upper control room.

It is preferred that attack on the terminal parts that engage in upper cabinet guide parts, which are supported on the side wall, on the rear wall or a false floor within the cabinet body. Preferred dimensions of the connection is formed below a shelf, which thus forms a Führungsstablar. For this purpose, the single support column can also be shorter than e.g. held on this furniture front, after which a management tray or a provided without the terminal tray is placed on the head of the single support column.

In the drawing, matching parts are provided with corresponding reference numerals.

1, in the exemplary embodiments shown, a cabinet body is numbered, in which the extractable rack, generally numbered 2, is arranged. In Fig. 1 the drawer frame 2 is shown in an extended position. In its storage position the pull-out frame is located in the cabinet body interior, according to which in the embodiment Fig. 1 the cabinet body 1 through the furniture front 3, which is held on the vertical front single support column 4 is closed. This vertical single support column 4 of the extension frame 2 is in the embodiment according to Fig. 3 located in the rear (rear) portion of the extension frame 2, wherein the cabinet body is closed, for example, by swing doors, in the embodiment according to Fig. 3 the sake of clarity are not shown.

The extension frame 2 comprises the already mentioned vertical single support column 4, to which a lower transverse bar 5 (extension frame profile) engages, which is movably guided in a lower cabinet body guide 6. The parts 5 and 6 together with the telescopic element 6.1 a total of a lower telescopic extension.

In the upper region of the vertical support column 4, a connection 7 is provided for the cabinet body guide 8, which also has a telescopic element 8.1, so that in the upper area also a telescopic extension is formed. The upper cabinet body guide 8 is formed on an intermediate floor, which extends to the side walls 1.1 and to the rear wall 1.2. On the vertical single support column 4, a connection 7 is provided in such a way that an upper crossbar and thus an upper head region 1.3 of the cabinet body 1 to be provided upper cabinet body guide is realized, so that this connection 7 is provided with such Höhenabstandsmaß to the inner head portion 1.3 of the cabinet body 1 is that in the storage position of the extension frame 2, a parking space or storage space 10 remains without affecting this cabinet drawer parts.

This creates a cabinet drawer that also pleases the overall visual impression.

In the embodiments shown, shelves 9 are provided as cabinet furnishings. For this purpose, the vertical single support column 4 has a slot-like guide 11 with undercuts 11.1 in which a connection connector 13 of a tray 9 can engage.

The slot-like guide 11 thus forms a guide on the single support column 4, in which the tray 9 or other furnishing can be slidably guided, so that without having to dismantle the tray 9, the user himself can adjust a tray 9 on the single support column 4 , By a suitable design of the connection connector 13 this can be done without tools.

How closer Fig. 6 to 8 shows, in the tray 9, a recess is provided which is bounded by an upstanding collar 14. As in the insertion position in Fig. 7 shown, the collar 14 surrounds the vertical single support column 4, wherein the abutment 15 in its vertical position ( Fig. 6 ) can be inserted into the opening of the slot-like guide 11 and after twisting ( Fig. 7 ) is in a horizontal position. By means of the eccentric clamping means 16, it can then be braced with the undercuts 11.1, after which the tray 9 is clamped to the single support column 4 ( Fig. 8 ).

In the embodiment shown in the Fig. 1 and 2 the vertical Einzeltragsäule 4 has a lower high extent than the interior of the cabinet body 1 in total and contributes as the upper end of the upper shelf 9, which is formed in the embodiment shown there as Führungsstablar by a connection 7 for the upper cabinet body guide 8 is attached to its underside , This guide is therefore less disturbing for the overall visual impression of the extension frame 2 than prior art designs of cabinet extensions, yet ensures a movement free movement of the cabinet drawer 1 total. In otherwise substantially identical structure is in the illustrated embodiment according to Fig. 3 the vertical single support column 4 of the extension frame 2 provided in the rear (rear) area. As well as in the embodiment of the Fig. 1 and 2 It is possible to form the vertical single support column 4 L-shaped and thus one-piece.

As in the embodiments of the Fig. 1 and 2 the upper portion of the extension frame 2 is formed free of cabinet body guides and the closure 7 laid in an area having such a height distance measure to the inner head portion of the cabinet body 1, that a storage space 10 remains, which is no longer by Auszuggestellteile or cabinet body guide parts is impaired. Again, the upper tray 9 forms a Führungsstablar again. In this embodiment eliminates a front furniture front. Rather, the cabinet body can be closed by swing doors, blind elements and the like. It is also possible that the extension frame 2 is not translational alone Moves performs, but also a pivoting movement or a translational movement combined with a gift movement.

How closer Fig. 5 It can be seen that the single support column 4 forming profile may be formed in two parts with one of the slot-like guide 11 opposite recess 16, in which a furniture front is to introduce their fastening parts. By introducing the second part 17 special strength properties in individual cases can be taken into account, for example, by a different choice of material or by different wall thicknesses. In addition, as in Fig. 5 indicated, even a frictional engagement element 18 are introduced, for example, to hold the tray 9 in a no longer shifted but not yet strained position due to its own weight in the slot guide 11.

The side walls 4.1 are in the embodiment according to Fig. 5 slightly oblique to the recess 16 is designed to widen, which also serves to keep the tray 9 with his collar after a shift safely on the single support column 4.

As in the FIGS. 9 and 10 indicated, a bus bar 18 may be provided within the slot-like guide 11, are also to be applied to the sliding sliding electrical conductors 19, for example, to provide lighting 20, which are mounted on the underside of a tray 9, with power.

In Fig. 11 a cabinet body 1 with the extension frame 2 of a vertical single support column 4 and shelves 9 is shown with the extension frame profile (cross bar) 5 and the lower cabinet body guide 6, in which the vertical single support column and thus the front panel 3 due to the weight load of the trays 9 a slight inclination to the vertical have taken so that would result in a gap S without a position adjustment.

How closer Fig. 12 As can be seen, this gap dimension S in the lower region of the front panel 3 is compensated by an automatic positional adjustment by compensating there for a positional adjustment dimension M by means of the force element 21 designed as a spring element. Thus, the lower and upper portions of the front panel 3 are equal to the cabinet body 1, in which the extension frame profile 5 has taken a likewise inclined position to the horizontal by the elastic member 21.

As in detail even closer Fig. 13 shows, the vertical single support column 4 is provided with a connection profile 5.1, which is hineinsteckbar in the extension frame profile 5 and move out together with this from the guide 6. Below the vertical single support column 4, the resilient element is attached to the connection profile 5.1, which is arranged in the guide 6. About a locking element 5.2, the connection profile 5.1 is connected to the extension frame profile 5. In this case, the locking element 5.2 is provided such that at this the connection profile 5.1 is brought to the position adjustment in relative positions by there is a pivot or pivot point is formed. When weight is the Spring element 21 according to, wherein the front region, that is, the region which is aligned to the vertical single support column 4, resiliently held in the guide 6, wherein in the front region, in the region facing away from the support column 4, the front end 5.1 in the extension frame profile 5 raises what the locking profile 5.2. allows. If the vertical single support column 4 is not loaded as high, it is held by the resilient element 21 due to the prevailing reaction forces in its vertical position.
