FRAME FOR A DRAWER

The invention relates to a frame for a drawer according to the preamble of claim 1.

A frame of the generic type is known from DE 10 2010 060 722 A1. The frame disclosed here has a connecting fitting as a functional device which with a base section is mounted to or formed on a frame adapter of a drawer frame. A release lever that can be operated manually is hinged to a locking lever and to the base section and extends into a free space in the frame adapter so that it can be operated manually by a user in the free space. The frame has proven itself well in practice, but requires a relatively large construction width.

For the realization of a frame with a narrower design, a structure with an inner shell and an outer shell is useful. The invention therefore has the object of further developing this frame with a view to a structure that offers the simple possibility of realizing a large number of visually and/or functionally different frame variants.

The invention solves this object by the subject matter of claim 1 and also creates a drawer for a piece of furniture with one or more frames according to one of the claims referring thereto. Advantageous embodiments of the invention can be found in the subclaims.

According to claim 1, the following subject matter is created: A frame for a drawer with a bottom and at least one such frame, wherein the frame comprises an inner shell and an outer shell attached to the inner shell, characterized in that a vertically upper contact region or a gap between the outer shell and the inner shell is covered by a cover strip. In the same way as a decorative strip or function strip, this cover strip offers the advantage that it can be used to easily provide other optical and functional variants of the frame or on frames without having to fundamentally change the structure of the frame. Thus, different colored and/or differently shaped cover strips can be provided in order to be able to change the design of the frame upwards in a simple way to suit the individual customer and/or in order to be able to realize attachments or the like on the frame in a simple way. The decorative strip complements the inner shell and the outer shell to form a shell that can also be designated as a three-part shell.

According to one variant, it may be optically and haptically advantageous for the cover strip to cover the edges of the outer shell and the inner shell vertically upwards.

Then, it can be provided according to an advantageous further development that

- the outer shell and the inner shell are slidably guided relative to each other by one or two sliding guides, and
- the one or at least one of said at least two sliding guides comprises one or more guide element(s) disposed between said outer shell and said inner shell.

The cover strips of claim 1 are particularly suitable—but not only—for such a construction. Furthermore, the one of the sliding guides can be constructed as an upper sliding guide and the at least one other of the sliding guides can be constructed as at least one lower sliding guide between the inner shell and the outer shell, and at least the upper sliding guide and/or the at least one lower sliding guide can have one or more guide elements arranged between the outer shell and the inner shell. This makes it possible to easily design sliding guides between an inner shell and an outer shell that are adapted to the respective design conditions. For example, on inner and outer steel shells, sliding guides cannot be formed directly between the inner and outer shells, or only with great design effort. This problem is easily solved by the guide elements provided on the respective sliding guide. It is advantageous for this purpose to attach the guide elements to the inner shell or the outer shell, preferably releasably, so that the corresponding component outer shell or inner shell can slide along them. The frame shall preferably have a type of elongated shell-type housing at least with an outer shell and an inner shell, between which a cavity is formed which is thus easily accessible.

The term “sliding guide” means that a first element is slidably guided on a second element and slides directly or indirectly on said second element. The sliding guide can, for example, be formed by a web of an element which slides on two or three sides, for example in a corner area or in a guide groove of a corresponding element.

The guide groove can be formed directly in the inner or outer shell or in another guide element attached to it.

The design is particularly simple and favorable if one or more of the upper guide elements is/are integrally formed with the cover strip. In this way, two functions—cover and sliding guide—are advantageously integrated into one component. However, another variant may also provide for the cover strip to be arranged on or fastened to one or more of the upper guide elements, in particular to be arranged in a slidable manner. This means that the cover strip and one or more of the guide elements are designed in one piece as an integral unit or assembled to form one unit.

It is simple and cost-effective if the cover strip is designed as a one-piece element. On the other hand, a particularly large number of variants is particularly easy to realize if the cover strip is made up of several pieces.

According to one variant, the cover strip is T-shaped in cross-section and has a horizontal leg and a vertical leg. In this way, the functions of fastening—e.g. by locking the longitudinal leg to another element of the frame—and covering—through the transverse leg—are very easy to combine. However, it can also be provided that the cover strip is F-shaped in cross-section and has one horizontal leg and two vertical legs. The second transverse leg can then function as a lateral cover. Otherwise, the function is preferably the same as for the explained T-shape. It is in any case practical and advantageous if the horizontal leg of the cover strip is designed as a cover leg which covers not only a gap or contact region but also a receiving channel of the frame in the upwards direction.

It may also be expediently provided that the one vertical leg of the cover strip is designed as a cover leg which covers the receiving channel of the frame on one side.

For the realization of a wide range of cover strip variants, it may also be provided that the cover strip has a strip base for attachment to the frame, which is provided with an upper mounting leg on which a cover strip or a function strip or a function element is mounted. Embodiments of these features are explained below with reference to the figures.

According to a preferred—but not mandatory—variant, the at least two sliding guides merely provide a linearly limited displaceability of the outer shell relative to the inner shell, as this is usually sufficient to advantageously ensure sufficient access to the interior space between the inner shell and the outer shell.

In the following, advantageous embodiments of frames for which the cover strips are particularly suitable are explained.

First of all, in another variant, it is useful and advantageous—although not mandatory

- if the outer shell and/or the inner shell are formed from one or more steel elements, in particular steel sheets. However, the invention is not limited to this but is also suitable for inner and outer shells made of other materials, such as light metal, especially aluminum. Unlike extruded profiles, webs or grooves cannot be easily formed on steel sheets. The guide elements are therefore particularly advantageous here.

In order to achieve good sliding properties and to provide the guide elements with a suitable geometry and shape in a simple way, it is advantageous if the guide elements are made of plastic.

It is advantageous constructively if the one of the sliding guides is designed as an upper sliding guide and the at least one other of the sliding guides is designed as at least one lower sliding guide between the inner shell and the outer shell, and that at least the upper sliding guide and/or the at least one lower sliding guides each have one or more guide elements arranged between the outer shell and the inner shell. The terms “upper” and “lower” refer to a vertical direction in an installation position of the frame on a drawer to an installation position closer—lower—relative to the drawer bottom and to an upper installation position further away from this drawer bottom.

It is advantageous if the guide elements are each arranged in a receiving channel formed between the inner shell and the outer shell. Preferably the receiving channel is formed by at least three or four walls, wherein at least one wall projects above the guide elements in its height. Two walls extending almost parallel to each other in vertical alignment with the drawer bottom are particularly preferred to have the same height. In this way, the guide elements are well protected and are visually concealed (with regard to the position of use of the drawer with a frame on a piece of furniture according to the invention) from the outer shell and the inner shell in the respective receiving channel. This channel is preferably completely or essentially completely covered by the cover strip.

It is advisable—although not mandatory—if two of the walls of the at least one receiving channel are formed by the inner shell and if one of the walls of the receiving channel is formed by the outer shell. It is advisable to attach the upper guide elements to the inner shell so that the outer shell is guided by the upper guide elements.

It is further advantageous if the guide elements are each fastened to the inner shell or to the outer shell and if the respectively corresponding element—the outer shell or the inner shell—has a guide groove formed correspondingly to the guide element and in the area of which the outer shell or the inner shell is slidably guided on the guide element or elements.

It is provided according to a further variant of the invention that the frame has two different lower sliding guides between the inner shell and the outer shell and that both of the lower sliding guides each have one or more of the guide elements arranged between the outer shell and the inner shell. In this way, limited mobility can be achieved in the lower area between the inner shell and the outer shell, which is sufficient to allow access to functional elements in the interior between the inner shell and the outer shell. In addition, it is thus possible to position the outer shell and the inner shell very precisely relative to each other.

It is conceivable that the guide elements of the sliding guides are each fastened to the inner shell and/or to the outer shell.

It is simple and advantageous in design if the guide elements engage displaceably in a guide groove of the corresponding element of the outer shell or inner shell.

It is provided according to a further variant that one or more sliding and/or positioning means are formed on one or more of the upper guide elements for fastening and/or positioning the top element “cover strip”. In this way, at least one upper guide element advantageously assumes a multiple function.

It is particularly advantageous in this respect if, within the framework of the realization of the multiple function, sliding guide means are provided on one or more of the upper guide elements, on which the cover strip is slidably guided with corresponding sliding guide means. The upper guide elements are thus used in an advantageous way both for the function of the sliding guide between the inner and outer shell and for the realization of other frame variants with the cover strip, with which, for example, other colors or shapes can be realized on the frame.

It is also advantageous and practical if sliding guide means are provided on the upper guide elements on which the cover strip is slidably guided with corresponding sliding guide means. In this way, two sliding guides are formed simultaneously on the upper guide rails. On the one hand this is the sliding guide between the inner and outer shell and on the other hand it is a sliding guide for the cover strip relative to one of the elements inner and outer shell.

It is constructively simple if the corresponding sliding guide means form a tongueand-groove sliding guide in their interaction.

It is structurally expedient and advantageous if the one type of lower guide element is fixed to the inner shell and slidably guided directly or indirectly on the outer shell and if the other type of lower guide element is fixed to the outer shell and slidably guided directly or indirectly on the inner shell.

With regard to the assembly of the guide elements, it is also advantageous if at least some of the lower and/or upper guide elements are fixed to the inner shell or the outer shell in a latching manner.

The upper and lower guide elements can be identical or different in design. It is then advantageous if the upper and/or lower guide elements as a whole are attached to the inner shell or outer shell. However, there are also advantageous embodiments conceivable in which some of the guide elements are fixed to the inner shell and some of the guide elements are fixed to the outer shell.

In particular, frames can be produced in which the inner and/or outer shell, preferably made of sheet steel, together form a body being essentially rectangular in cross-section with a maximum width B₃of less than 15 mm.

Further advantageous embodiments of the invention can be found in the subclaims.

FIG. 23 shows a variant of the drawer from FIG. 22;

FIGS. 24, 25 each show a side view of a section of further drawers with a frame with a structure with inner shell, outer shell and a cover strip.

FIG. 1 shows a piece of furniture designed as cabinet furniture 2. The cabinet furniture 2 has a furniture body 3. Three drawers 4, 5 are inserted here in furniture body 3 by way of example. The drawers 4, 5 are slidably guided in the furniture body 3 so that each of the drawers 4, 5 can be pulled out of the furniture body 3 into an open position and pushed back again into a closed position.

The drawer 5 illustrated in FIGS. 2a and b has a front panel 6a, which in this case is designed as a relatively high front panel 6a as an example. Drawer 5 also has two side frames—hereinafter also referred to as frames 1. The frames 1 are preferably constructed with two shells. The frame has a kind of elongated shell-like housing with an outer shell 11 and an inner shell 10.

The outer shell 11 is held on the inner shell 10 and can be moved relative to it. Preferably, the outer shell is held on the inner shell so that it can be moved to a limited extent. The inner shell 10 has a narrow cavity in each case with the outer shell 11.

The term “inner shell 10” and “outer shell 11” does not mean that they have to be constructed in one piece. The inner shell 10 and the outer shell 11 can in turn be composed of several elements such as metal strips, so that these metal strips interact to form the inner shell and the outer shell 10, 11.

Drawer 5 also has a rear panel 12a and a drawer bottom 12b. Preferably—but not necessarily—the outer shell 11 and the inner shell 10 are made of sheet metal, especially sheet steel. However, they can also consist of other materials. Preferably, the inner shell 10 and the outer shell 11 are each manufactured in one piece or in several pieces from one or more sheet(s), in particular from steel, which have been bent over to form sections and on which, if necessary, recesses and the like are formed by punching, cutting or the like.

It is also preferred if the outer shell 11 and the inner shell 10 form a frame with a relatively small, i.e. “narrow”, construction width, which (perpendicular to FIG. 3a) is preferably less than 15 mm, in particular narrower than 12 mm. The invention can be used advantageously especially with such narrow frames 1.

FIG. 2b does not show the outer shell 11 of the frame 1 of drawer 5 which is on the left as seen by the operator of drawer 5 and the inner shell 10 of the frame 1 which is on the right as seen by the operator of drawer 5.

Several functional devices are arranged on each of the frames 1, which are essentially arranged in the installation space between the outer shell 11 and the inner shell 10. These functional devices include, for example, one or more locking devices and one or more fastening elements. The drawer in the area of each of the two frames 1 has at least one, here two connecting fittings 7a, 7b, with each of which the front panel 6a can be attached to the frame.

For this purpose, the front panel 6a of each connecting fitting 7a, 7b can be connected or is connected in the assembled state to a corresponding locking device 9a, 9b on the corresponding frame 1 on the left or right via a carrying device 8.

Drawer 4 with low front panel 6b has the same design as drawer 5 with high front panel 6a. Differences between the two drawers 4, 5 exist in particular in the height of the front panel 6a or 6b (and possibly the rear panel) and thus in the height of the frames 1, which are correspondingly lower in the case of drawer 4 with a low front panel 6b. As a result, the frames 1 of the drawer 4 with low front panel 6b have only one locking device 9a or 9b.

In order to provide access to the functional element(s) located wholly or partially in the intermediate space between the inner shell 10 and the outer shell 11, it is advantageous if the inner shell 10 is displaceable relative to the outer shell 11, preferably with limited displacement (for illustration see for example FIG. 16).

According to a preferred embodiment, the outer shell 11 is designed in one piece. The outer shell 11 also has an outer wall section 13, which essentially or completely forms the visible outer wall of the frame 10 on the outer wall/side facing away from the drawer bottom 12b. Towards the rear wall 12a, the inner shell 11 here is shorter by its width B than the outer shell 11.

Preferably a lower edge 14 of this outer wall section 13 is bent 180° towards the inner shell 10. A channel-like lower guide groove 15 is formed on the outer shell 11 (FIG. 3b).

Furthermore, an upper edge 16 of this outer wall section 13 is preferably bent by a total of approx. 180° towards the inner shell 10, so that also a channel-like upper guide groove 17 is formed.

The upper edge 16 also preferably forms a resiliently acting angulation 19 which extends downwards from the cover strip section 18. Thus the upper edge 16, together with the cover strip section 18 and the angulation 19, jointly forms the upper channel-like guide groove 17 on the outer shell 11. According to a preferred embodiment, the inner shell 10 is designed in two pieces. However, it can also be integral or consist of more than two metal sheets (not shown here). Here the inner shell 10 has an inner wall section 20 and a container rail 21 attached to the inner wall section 20 with one or more attachment points, wherein these points can be produced by joining methods such as riveting, clinching or welding.

One or more of the functional elements described above is/are defined on the container rail 21. It increases the stability of the respective frame 1 and simplifies assembly.

The inner wall section 20 serves, among other things, to optically cover frame 1 towards the inside—i.e. towards the drawer bottom 12b.

The upper edge 22 of the inner wall section 20 (and here also that of the container rail)—see FIG. 3b—is bent outwards or towards the outer shell 11 in such a way that it lies below the upper guide groove 17 and forms a carrying leg 23 there in the manner of a cross beam. Between the carrying leg 23 and the inner and outer shells 10, 11, an upper receiving channel K1 is thus formed towards the upper edge area.

The carrying leg 23 is used here to fasten one or more first—upper—guide elements 24. These are arranged in the upper receiving channel K1 and are well protected and optically concealed there. The outer shell 11 glides on them. They therefore form a first, upper sliding guide S1 with the outer shell 11 (see FIG. 3b).

Preferably several of the upper guide elements 24 are distributed in a row at a distance from each other on the carrying leg 23 of the inner shell 10. The carrying leg 23 and an adjoining wall area of the inner shell 10 form two of the walls of the upper receiving channel K1. Two other walls of this receiving channel K1 form the outer shell 11. The upper receiving channel K1 is thus closed all around. The upper guide elements 24 are therefore not visible from the outside in their installation position on a drawer.

The guide elements 24 can be fixed in a stationary manner in the receiving channel K1, for example, with screws or rivets and/or locking means or the like. Preferred—because simple and uncomplicated—is a fastening with at least one detent hook 40 or more detent hooks, which engages/engage into a detent recess 41 of the carrying leg 23 and/or the container rail 21 (FIGS. 3b and 3c).

The upper (and also the further) guide elements 24 each form sliding elements, wherein according to FIG. 3b the upper guide elements engage directly into the upper guide groove 17 of the movable outer shell 11. In this case, the resilient leg rests resiliently on the side of the guide elements 24. In this way, the outer shell 11 is guided in a simple way in the upper area on the guide elements 24 of the inner shell 10 so that it can be moved easily and safely. The first—upper—sliding guide S1 is formed between the outer shell 11 and the inner shell 10.

Since the angulation 19 is preferably designed as a resilient leg, which laterally engages resiliently in a lateral recess 24a of the upper guide elements 24, a particularly good fit of the outer shell 11 in this area is achieved on the guide elements 24. In this way, a lift-off safety device for the outer shell 11 from the inner shell 10 can be easily implemented.

The lift-off safety device can also be implemented in other constructive ways.

This one or more upper guide elements 24, 24″ (and 50) preferably consist of a plastic. The latter also applies to further guide elements 25a, 25b to be explained below.

In addition, the outer shell 11 is also displaceably guided further down—here at the lower edge—towards the inner shell 10 with further guide elements 25a, b relative to the inner shell 10.

In this area further down, at least one further sliding guide S2 is formed between the inner shell 10 and the outer shell 11. Preferably even two further lower sliding guides S2 and S3 are provided (FIG. 3b and FIG. 5a).

It is conceivable to provide only one type of lower guide element. According to the figures shown, on the other hand, two different types of lower guide elements are provided which are designated 25a and 25b in the drawings and which are optimally adaptable to the tasks and geometries in the area of the two lower sliding guides S2, S3.

The first lower guide elements 25a are preferably fixed on the outer shell 11 to the lower guide groove 15 using a forming process, preferably in such a way that the joining process leaves no visible traces from the outside. They serve as combined guide and fixing elements and also serve to hold the outer shell 11 on the inner shell 10. The lower middle guide elements 25a engage advantageously with a vertically aligned guide leg 26b fixedly and immovably in the lower groove 15 of the outer shell 11.

According to FIG. 3c, four of these first lower guide elements 25a are provided as examples. They preferably have a T-shape in section (see FIGS. 10 and 11). The preassembled guide elements 25a on the outer shell 11 carry a horizontally aligned cross beam 27 of the inner shell 10 with a horizontally aligned leg 26a after the inner shell 10 has been placed on it. This cross beam 27 limits a lower receiving channel K2 for the lower guide elements 25a, b upwards. The one other wall of this receiving channel K2 is formed by the outer shell 11 and the other by the inner shell 10. Since the middle lower guide elements 25a are attached to the outer shell 11, the actual sliding guide S2 is formed on these guide elements 25a towards the inner shell 10, here on the container rail 21.

The lower middle guide elements 25a are thus advantageously positioned between the inner shell 10 and the outer shell 11, where they are concealed and well protected.

At least one of the central (first lower) guide elements 25a secured to the outer shell has a spring element 30—adapted to engage a window or the like of the inner shell upon displacement of the outer shell 11 relative to the inner shell to releasably secure the outer shell 11 relative to the inner shell 10 in a final assembly position which can only be released in a special case such as a maintenance case. Here the spring element 30, in particular a leaf spring, has a detent lug 31, which engages in a latching manner in a window of the inner shell when the outer shell 11 is moved (see FIGS. 10 to 12).

There are also two outer guide elements 25b—see FIGS. 4 to 8—which are each provided in the end area (i.e. towards the front panel and towards the rear panel) of frame 1.

These outer guide elements 25b stabilize in particular the outer end areas of the frame in the end area of the inner shell 10 and the outer shell 11. They are also arranged in the lower receiving channel K2. However, they are fixed to the inner shell 10 and the outer shell 11 is movable relative to them or on them.

The outer guide elements 25b each preferably have a detent means such as a detent hook 28, which is/are attached to a corresponding detent means—for example to a window 29 of the inner shell 10.

Also the two outer lower guide elements 25a, b are preferably formed in a T-shaped manner in section, so that three legs 26a, b, c are formed on them.

The horizontal leg 26a has the detent hook 28 and is fixed to the inner shell 10, namely in a receptacle 47 which is U-shaped in section and formed in the end area of the inner shell 10. The lower vertical leg 26b, on the other hand, engages in the guide groove 15 of the outer shell 11, which is open vertically upwards, and is slidably guided there.

(Short) vertical webs 32 of the guide elements 25b engage in slots 33 of the cross beam 27 of the inner shell 10 and thus additionally secure the edge area of the frame against pulling apart the outer shell 11 and the inner shell 10 (see in particular also FIG. 5b).

The lower vertical leg 26b of these outer guide elements 25b, which form a second type of lower guide elements, engages in the lower guide groove 15 of the outer shell 11. In this way, the third lower sliding guide S3 is easily formed.

The two sliding guides S2 and S3 thus allow only limited displaceability corresponding to the distance between the two guide elements 25a, b of different type. However, this is sufficient to provide access to the functional devices described above in the interior between the inner shell 10 and the outer shell 11 (see again FIG. 16).

In total, with the two types of lower guide elements 25a and 25b, two different lower sliding guides S2, S3 are formed between the outer shell 11 and the inner shell 10, which allow at least a limited displacement until the guide elements 25a, b abut each other.

The first guide elements 25a are preferably fixed to the outer shell 11 at its guide groove by a forming process, preferably in such a way that the joining process leaves no visible traces on the opposite side of the outer shell “on the outside”.

According to FIG. 3c, four of the middle guide elements 25a of the first type are provided as examples. In addition, two of the outer guide elements 25b of the second type are provided, which are each provided in the end area (i.e. towards the front panel and towards the rear panel) of frame 1. These outer guide elements 25b in particular stabilize the outer end regions between the inner shell 10 and the outer shell 11. The outer guide elements 25b preferably each have a detent means such as a detent hook 28, which is/are fastened to a corresponding detent means—for example to a window 29 here on the (continuously or sectionally provided) guide groove 15 of the outer shell 10.

All lower guide elements 25a, b are preferably approximately T-shaped in section, so that three legs 26a, b, c are formed on them, which can engage in corresponding grooves of the outer shell 11 and or the inner shell 10.

According to one variant—see FIG. 13ff—a further component is provided on the shell of frame 1. This component is a cover strip 35-A.

When mounted, this cover strip 35-A optically closes off the inner shell 10 from the outer shell 11 and thus replaces the upper horizontal web 18 of the outer shell 11. The cover strip has a recess towards the rear wall 12a (with the width B of the rear wall 12a).

The cover strip 35-A, like a decorative strip, offers the advantage that it can easily be used to provide further optical and functional variants of the frame or frames without having to fundamentally change the structure of the frame. This means that cover strips 35-A in different colors and/or shapes can be provided in order to be able to easily modify the design of the frame upwards to suit the customer's individual requirements and/or to be able to easily realize attachments or the like on the frame. The decorative strip complements the inner shell 10 and the outer shell 11 in comparison with FIG. 3 (two-part shell) to form a shell that can also be described as a three-part shell.

In this case it can be provided that the upper edge 16 of the outer shell 11 may still be converted into a kind of guide groove 17, but into a narrower upper guide groove 17, in which the first upper guide webs 36 of the upper guide elements 24′ engage.

Further guide webs 37a, b on the upper guide elements 24′ can be formed on the upper guide elements 24′, in which one or more webs 39 of the cover strip 35-A can engage, so that this is also slidably guided on the inner shell 10. The guide webs 37a, b can also be formed to be spring-loaded so that when the web 39 is pushed vertically to the drawer bottom, they move out of the way. The guide webs can also form a type of dovetail guide groove 38 and the web 39 can be formed in a dovetaillike manner. The guide elements 24′ thus have the advantage of performing a double function for guiding both the outer shell 11 relative to the inner shell 10 and for guiding the cover strip 35-A on the outer shell 11 or on the inner shell 10.

The guide elements 24 and 24′ each have a base on which one or more of the guide webs (36, 37a, 37b) are formed.

It is advantageous if the inner shell 10, with the exception of the guide elements 24′, is constructed identically to the embodiment variant of FIGS. 1 to 12, so that further variants of frames can be provided or converted to such by virtually simply exchanging the upper guide elements 24 for the other guide elements 24′ and providing the other outer shell 11 and the cover strip 35.

Also according to the variant of FIG. 19, a cover strip 35-B is provided on the shell of frame 1. According to this (in deviation from FIG. 13), one or more upper guide elements 24 together with the cover strip 35-B are designed in one piece.

For this purpose, the cover strip 35-B has a cover leg 50 which covers the receiving channel K1. The cover strip 35-B also has a foot 51 connected to the cover leg 50. This foot 51 here is U-shaped and has two longitudinal legs 52, 53 and one transverse leg 54. The one of the longitudinal legs 52 is connected to the cover leg 50 and the other longitudinal leg 52 engages in the groove 17 as the upper sliding guide.

The cover strip 35-B—as well as the other cover strip variants described in this document—can be manufactured in various ways. They can be designed as an injection molded part or as a cast part or as a cut-to-length piece of an extruded profile. They can also be made of a wide variety of materials, in particular plastic or light metal.

The solution of FIG. 19 is more cost-effective than that of FIG. 13, which, however, allows an even greater variety of designs.

FIGS. 20
a-d also show another variant of a cover strip 35-C. This cover strip 35-C is similar to the cover strip 35-A of FIG. 13 with regard to the way it is fitted.

When mounted, the cover strip 35-C also optically closes off the inner shell 10 from the outer shell 11, thus replacing here at least the upper horizontal web 18 of the outer shell 11. The cover strip has a recess towards the rear wall 12a (with the width B of the rear wall 12a).

The cover strip 35-C also has the advantage of being a decorative strip in the same way that it can be used to easily provide other optical and functional variants of the frame or on frames without having to fundamentally change the structure of the frame.

Between the cover strip 35-C and guide elements 24 there is again a fastening. This can be designed as a dovetail guide, which enables displacement in the longitudinal direction of the frame and/or clipping in vertically to the longitudinal direction of the frame of the cover strip 35-C on the guide elements 24.

The cover strip 35-C itself is designed in several parts. According to FIG. 2, a strip base 60 is provided for attachment to the guide elements 24. The strip base 60 here is T-shaped in cross-section and has a lower, here vertical, fastening foot 61 and an upper, here horizontal, mounting leg 62. The mounting leg 62 is designed in such a way that a cover strip 63 can be placed on it. This cover strip 63 is the element that is actually visible from the outside. The cover strip 63 can in turn be coated with a cover foil 64 (FIG. 20c), e.g. with a self-adhesive cover foil 64. An attachment is formed between the cover strip 63 and the horizontal mounting leg 62. This attachment may have an adhesive film 65, preferably a double-sided adhesive strip 65, which is placed between the receiving leg 62 and the cover strip 63. In this way, the cover strip 63 can be easily and compactly attached to the horizontal mounting leg 62.

However, it is conceivable to also provide other ways of fastening the cover strip 63 to the horizontal mounting leg 62, such as detent connections or the like.

The multi-part design of this selected structure ensures that there are a large number of possibilities for using simple means to provide a wide variety of cover strips 35-C in order to give the respective frame a preferred appearance. The strip base 60 is not changed for this purpose. The various variants can be implemented by preselecting or, if necessary, changing the cover strip 63.

Thus the cover strip 63 can be rectangular in cross-section as shown. However, it also can have a large variety of other cross-sections, thus a cross-section which is upwardly rounded off (not shown). In addition, the cover strip 63 can also be made of a wide variety of materials, particularly those that would be less suitable for direct attachment to the frame, but which offer a particularly attractive appearance. According to one variant, the cover strip 63 then consists of a wood-based material or a wood substitute material. But it can also be made of plastic or metal, or it can be made of ceramics, for example.

Further variants of cover strips 35 are characterized in that the respective cover strip 35 is used to implement one or more further functions. Variants of this embodiment are shown in FIGS. 21 to 23.

The first of the variants is illustrated by FIG. 21a-g.

According to FIG. 21a-g (see in particular FIG. 21c) it is intended to provide a cover strip 35-D with a first guide means 70, on which a top strip 71 with a corresponding second guide means 72 can be placed. The cover strip 35-D here is basically similar to the cover strip 35 from FIG. 13 and is arranged analogously on the frame. But it has the first guide means 70.

The first guide means 70 may be configured as a groove or web in the main extension direction of strips 35-D and 71 and the corresponding second guide means 72 on the top strip 71 may be configured as a web or groove corresponding to the first guide means 70. Together these two guide means form a sliding guide.

A functional element can be attached to the top strip or it can be molded directly onto it.

According to FIG. 21, the functional element is placed on the top strip 71. As further illustrated in FIG. 21, the functional element can be designed as a top drawer 73. The top drawer is then preferably connected to two side frames 100, each with one of the base strips 71, which can each be attached to one of the two side frames of a drawer. If the frame length of the top drawer is smaller than that of the frame on which it is mounted, it can be moved to a limited extent on these two frames.

The top drawer can be designed in a simple integral design with the base strips and can be made of plastic, for example. This embodiment is not shown here. It can, however, also be made up of several parts and be constructed like the drawer on which it is mounted, especially with regard to the frames. It is then shorter than the bottom drawer only in its direction of movement or insertion. These variants are shown in FIG. 21a) to g). In this way, the top drawer 73 is optically well matched to the drawer on which it is mounted.

It can also be advantageously provided in this case that the top strip 71 engages at the bottom in the frame 100 of the top drawer 73, for example it is clamped and/or engaged. The top drawer has two side frames 100 which are fitted in this way to the lower frames of the lower “main drawer” 4. It may also preferably have a base 101, a rear panel 102 and a front panel 103 (FIG. 21e).

FIG. 22
a) also shows a side view of a section of a drawer with a frame with a configuration with inner shell, outer shell and a cover strip 35-E, on which an internal drawer insert 74 is designed as a functional element. The cover strip is essentially designed as in FIG. 13 and can be mounted to the frame as in this case. The internal drawer insert 74 laterally adjoins the cover strip 35-E. It can be integrally molded onto said strip. Preferably, one of the cover strips 35-E is formed on each side of the internal drawer insert. The two cover strips 35-E can be designed in one piece with the internal drawer insert 74. The internal drawer insert 74 can be designed to be placed in the drawer in a vertical positioning movement. However, it can also be provided that it can then be pivoted together with one into its end position. FIG. 23 shows such an embodiment.

The internal drawer insert 74 is thus easy to assemble. It may contain one or more interior partitioning means, e.g. it can have one or more walls 75 that divide it into compartments 76.

According to FIG. 24 the cover strip 35-F has an F-shape with two vertical legs 85, 86 and one horizontal leg 87. The horizontal leg 87 forms the actual optical end of the frame towards the top. The one vertical leg 86 is used for fixing to one of the several guide elements 24, as described for example in FIG. 13. As already discussed, the cover strip 35-A shown in FIG. 13 has a T-shape. In the embodiment example of FIG. 24, this T-shape is supplemented by the second vertical leg 86. The further vertical leg 86 of the cover strip 35-F directly replaces an upper section of the inner wall, in particular the inner shell 10 of the frame, so that an upper receiving channel K1 is formed with this vertical leg again in a simple manner, which is essentially closed around the circumference except for the gap.

According to FIG. 25, the cover strip 35-G is again F-shaped. Its two vertical legs 88, 89 are arranged on the frame. An upper sliding guide is not provided or is implemented completely independently of the cover strip 35-G with guide elements not shown here.

The cover strip 35-G can be attached to the frame 1 in different ways—e.g. adhesive or latching. It forms an attractive upper optical finish of frame 1. It has an F-shape with two vertical legs 88, 89 and the horizontal leg 87, wherein the two vertical legs 88, 89 are directed downwards towards the frame and can rest on it.
