Description

State of the art

Hollow chamber frames for drawers serve to form a drawer side wall and usually consist of a bent sheet metal part. Such Hohlkammerzargen have frequently or depending on the model of the associated drawer furniture on a corresponding appearance and differ z. B. in the color.

Often an individual adaptation of the hollow chamber frame is desired, for example, elements of glass or rail-like struts are added to the hollow chamber frame. The DE 20 2005 008 286 U1 relates to a drawer with two side frames, wherein at least one functional profile strip is fixed.

Purpose and advantages of the invention

Object of the present invention is to improve a hollow chamber frame for a drawer, a drawer and a corresponding furniture with drawer in terms of a desired design.

This object is solved by the independent claims. The dependent claims relate to advantageous and expedient variants of the invention.

The invention is based on a hollow chamber frame for a drawer, wherein the hollow chamber frame has a frame body, which forms a side wall of the finished drawer in the use state, wherein the frame body has an outer wall and an outer wall opposite to the inner wall spaced apart, and the outer wall and the inner wall via one on the Zargenkörper upper side existing web are connected to each other, wherein an optionally attachable to the Zargenkörper decorative element of the Hohlkammerzarge on the outer wall and / or inner wall of the Zargenkörpers is arranged so that at least a portion of a surface of the Zargenkörpers is covered by the decorative element to an appearance of To influence hollow chamber frame. The inner wall, the web and the outer wall are preferably designed in one piece, in particular from a sheet metal material or a plastic material. This is advantageous in terms of manufacturing and shaping.

The decorative element has a surface element, an abutment portion and a gripping portion, wherein the gripping portion engages around a lower edge portion of the outer wall from below and the abutment portion is located at the top of the frame body in the region of the web of the Zargenkörpers in abutting contact for attachment of the Zargenkörper attached decorative element. Also, the decorative element is in particular integrally formed, for example, from a sheet metal material or other material.

According to the invention, a shoulder is formed between the part of the contact section, which bears against the web of the frame body, and an inner side of the contact section, which is upwardly spaced from the web. Thus, the attachment of the decorative element on the frame body is facilitated and the Defined connection point of the contact section defined on the web. With the paragraph, in particular a small air gap between the top of the web and the inside of the decorative element, which adjoins the contact section realized.

The frame body preferably has a ready-to-use surface, which is for example painted or powder-coated. With its surface element, the decorative element preferably covers the entire visible height of the outer wall and / or the entire visible height of the inner wall of the frame body. This is preferably a complete cover or strip-shaped partial cover of the Zargenkörpers reached. The decorative element preferably extends over more than 20%, in particular more than 30% in particular more than 90% over the length of the Zargenkörpers based on the total length between a back and a front side of the drawer whose distance bridges the Zargenkörper.

The inner wall of the Zargenkörpers limited laterally an interior of the fully assembled drawer. The Zargenkörper preferably integrally constructed, if necessary, on a bottom receiving portion is in particular a downwardly open U-profile, which is bent twice angularly to form the web. The frame body is in particular tuned so that no receiving volume for a drawer guide system is present. The drawer slide is present or mounted in the drawer mounted on a furniture body preferably outside the volume of the Zargenkörpers, for example, a drawer rail at the bottom of the drawer bottom and a carcass rail attached to a furniture carcass inner wall. On the Zargenkörper a receiving portion for supporting the underside of a bottom of the drawer bottom is present, in particular in the manner of a laterally open U-profile or an angle plate.

The gripping portion closes along a lower end of the surface element and the abutment portion adjoins it along a lower end opposite upper end of the surface element thereto. About the gripping and contact section is the simple but secure releasable attachment of the decorative element on the frame body, with the gripping and the abutment portion at the bottom and top of the frame body pressing a clamping or optionally a locking connection is provided.

With the attached decorative element, the spatial shape of the Zargenkörpers is preferably maintained, apart from a comparatively small increase in the wall thickness of the hollow chamber frame by the outside of the outer wall, the web and / or the inner wall of the Zargenkörpers attached decorative element. The decorative element is designed so that the decorative element preferably bears snugly on the outer contour of the Zargenkörpers. The wall thickness of the decorative element is preferably more than 0.1 millimeters, for example more than 0.2 millimeters to, for example, 1 or 2 millimeters to about 5 millimeters.

A separate decorative element is to be understood in particular as a cover element to be distinguished from the frame body, which differs from the remaining surface of the frame body, in order to allow a variant differing only in design. In particular, the Zargenkörper is also formed without an existing decorative element for the finished state of use of the drawer, so constructed fully functional to form without decorative element, the side wall of the drawer. The hollow chamber frame without or with decorative element forms a finished side wall of a drawer. The drawer side wall with the Zargenkörper alone is completely finished in terms of their mechanical and technical functionality. In other words, the decorative element is not necessarily necessary for the function or the provision of the function-ready hollow chamber frame.

The decorative element can completely cover the visible surface of the frame body, ie web, outer and inner wall, or only in regions, then in particular strip-shaped over a partial length in the longitudinal direction of the Zargenkörpers considered. Preferably, the outer wall and the web is covered by the decorative element or the inner wall and the web. In an overlap of the outer and the inner wall together with the web attachment preferably takes place at a lower edge of the outer or inner wall and by the abutment contact of the contact section on the web. The attachment of the decorative element is optionally carried out by placing it from above and lowering on the Zargenkörper.

As an alternative to surface-closed training, the Decorative element openings or passages or holes z. B. have a perforated pattern, so that within an edge profile of the decorative element under the decorative element existing corresponding areas of the surface of the frame body are visible.

It is also conceivable that the decorative element is transparent or partially transparent.

The decorative element is preferably mounted in the immediate vicinity of the surface of the Zargenkörpers. Particularly preferably, the decorative element is subsequently detachably attachable to the frame body. Preferably, the attachment of the decorative element by hand or manually possible, in particular without aids such. B. a tool.

Preferably, the decorative element has an outer surface that is flat and smooth or even. Alternatively, the surface of the outside of the decorative element may have a structure for design reasons.

The inner side of the contact section is designed to fit above in the region of the Zargenkörper web preferably tuned for it.

Preferably, the contact portion and the gripping portion are slightly elastically deflected relative to the surface element of the decorative element.

Further, it is advantageous that the decorative element and the frame body are matched to one another such that the contact section along the longitudinal extent of the web is in contact with the web on the web. Thus, a stable support of the decorative element can be achieved over the covered by the decorative element length of the Zargenkörpers. Preferably, the contact portion comes at several points or over the entire length of the cover in abutting contact with the web. For this purpose, the inside of the contact section and / or the web are matched accordingly formed or shaped.

Further, it is advantageous that the abutment portion in the region of a longitudinal edge of the web of the Zargenkörpers abuts the top of the Zargenkörper particular presses. The longitudinal edge of the web of the Zargenkörpers may be an inside or outside outer edge of the z. B. strip-shaped web. The inside longitudinal edge may be formed by a bend of the web at the transition to the inner wall of the Zargenkörpers or the outer longitudinal edge may be formed by the deflection of the web at the transition to the outer wall of the Zargenkörpers. The longitudinal edge preferably has a curved outer shape, but may also include a sharp edge or line edge.

To the region of the longitudinal edge in particular includes a flat portion which extends into a subsequent to the web top edge contour z. B. extends according to a bending radius.

A longitudinal edge of the web can also be formed on the upper side of the web between the outside and the inside longitudinal edge, for example by a profiling of the web as a groove or a plurality of notches, recesses, depressions and / or protrusions arranged in a line over the length of the web ,

Another advantage is that a surface element facing away from the free end of the abutment portion is formed flush with a surface of the inner wall. The contact section ends with its inner longitudinal edge, which forms the free end, in the region of a vertical or vertical plane in which the surface of the inner wall is located. Advantageously, it can not hook on removal of an object from the drawer this at the investment section. This avoids that the decorative element attached to the frame body is inadvertently released or lifted off the frame body.

It is also advantageous that the decorative element of the bridge the Zargenkörpers covered upwards. In particular, the web is covered by the contact section or a decorative element top. Preferably, the bridge is completely covered over the corresponding length of the decorative element. Thus, the upper-side appearance of the hollow chamber frame is not determined by the Zargenkörper, but by the decorative element.

An advantageous variant of the invention is characterized in that the gripping portion has a spring portion for resilient engagement with the lower edge portion of the outer wall. In this way, in particular in the attachment of the decorative element of the U-shaped portion at the bottom of the outer wall of the Zargenkörpers resiliently come into abutment, whereby the assembly or threading of the decorative element is facilitated. In addition, a resilient pressing force is provided in the attached decorative element by the spring portion at the bottom of the outer wall. Thus, the holding function for holding the decorative element on the outer wall is improved.

Further, it is advantageous that the gripping portion has a section U-shaped section. The U-shaped portion is preferably resilient, for example on a multiply bent lower edge of the surface element. At the free end of the bent edge of the U-shaped portion may be formed, for example, as a notch. The bent-over edge may have an obliquely upward resilient arm on which the U-shaped section is present.

For example, if the U-shaped portion is configured as a double right angle bent edge on the surface element or not resilient, an elastic element, for example an elongate elastomer insert, may be inserted into the groove formed by the U-shaped section, so that the elasticity the deformable insert such. B. an O-ring cord, when the lower edge of the outer wall of the frame body is seated from above, provides height compensation. A height compensation is in practice advantageous or necessary because due to z. B. manufacturing tolerances, the height of the outer wall of the Zargenkörpers may vary slightly.

A further advantageous embodiment of the subject invention is characterized in that the abutment portion has a protruding shape on its inner side facing the web. The supernatant is accordingly downwardly relative to an inner side of the abutment portion. By means of the above form, the abutment section defined in contact with the bridge.

In addition, it is advantageous that the abutment section has a contact surface, the shape of which is formed such that the abutment surface conforms to the frame body in the region of the web, in particular in the region of the longitudinal edge of the web. The contact surface may have a flat, angled and / or a curved contour, which conforms to a corresponding flat, angled or curved counter contour in the region of the web or the longitudinal edge of the web. This achieves surface contact over the length of the web. In this way, comparatively large holding forces for holding the decorative element at the top of the frame body can be provided.

According to a preferred modification of the invention, the contact section has a bent contact surface.

In particular, the shaped abutment surface is designed in accordance with a bending radius or a line edge of the relevant longitudinal edge of the web.

Preferably, a concavely curved contact surface snugly fits on the inside of the contact section of the decorative element to a convexly curved contour of the longitudinal edge of the web. The longitudinal edge of the web which is in contact with the contact surface is preferably an inner longitudinal edge of the web. The inside edge of the web lies on the longitudinal side of the web, which faces away from the surface element or with respect to a longitudinal edge of the web, which adjoins the surface element. The part of the decorative element or the abutment section which is aligned at an angle to the surface element at the top is slightly elastically deflectable about a point in the region of the curved transition between the planar element and the abutment section, which facilitates the assembly of the decorative element. The abutting fitting abutment portion is therefore biased slightly with the decorative element usually something, the abutment portion presses against the web or the longitudinal edge of the web from above.

Preferably, the contact portion is located at the top of the web at exactly one longitudinal edge of the web of the Zargenkörpers or the contact portion is spaced from a further longitudinal edge of the web. This avoids overdetermined storage of the decorative element on the web.

It is also advantageous if an abutment structure projecting in the direction of the surface of the outer wall of the frame body is formed on an inner side of the surface element of the decorative element. This avoids unwanted vibration and / or bending of the surface element inwards. The abutment structure may be formed, for example, in the manner of a continuous or interrupted web or a rib. The investment structure may be parallel, transverse or oblique to an outer edge of the decorative element. In the attached state of the decorative element is a free Surface of the investment structure on the surface of the outer wall at preferably distributed over the surface of the outer wall at several or different locations, for. B. linear. On the inside of the decorative element, which is not visible in the attached state, esp. For technical reasons, the investment structure may be present. For example, an inner side of the surface element has a protruding structure with shoulders or, preferably, a rib-like structure, which in particular is uniform. Thus, the stability of the decorative element and a desired concern to the Zargenkörper can be specified.

An additional advantage of a modification of the invention is the fact that the decorative element over at least a part of the length of the frame body covers a surface of the outer wall and / or a surface of the inner wall and a surface of the web. The decorative element can thus determine an outer appearance of the hollow chamber frame or the drawer side wall completely or in part, which is done with the cover of the outer wall and the web of the Zargenkörpers, and / or determine the appearance of the inside of the drawer side wall, which with the Cover the inner wall and the web of the Zargenkörpers is possible. When designed as a bottom open U-shaped decorative element, this can overlapping the complete Zargenkörper is present.

Preferably, the decorative element covers with its cover width, which results between preferably parallel vertical side edges of the decorative element, a strip-shaped region of the Zargenkörpers or the total length of the Zargenkörpers.

Finally, it is advantageous that the attached decorative element does not completely cover the surface of the frame body which is visible without the decorative element. Accordingly, the decorative element covers only a partial length of the Zargenkörpers, is therefore shorter than the Zargenkörper and / or the decorative element has recesses or openings, for example, a hole pattern, so that when attached decorative element, the underlying surface of the Zargenkörpers is partially visible or, conversely, only partial areas are covered by the decorative element. This allows different design variants of the drawer side wall set up variable. For a variety of different design variants of decorative elements can be made suitable matched to a Zargenkörper available, of which in each case a desired is attached to the Zargenkörper. Also, a change of the drawer design is possible at any time and uncomplicated by replacing or removing a decorative element.

The invention also extends to a drawer with a hollow chamber frame, which is designed according to one of the above training variants.

Finally, the invention relates to a piece of furniture with a drawer designed as mentioned above with a hollow chamber frame according to the invention which has a decorative element.

For themselves corresponding elements of the different embodiments, the same reference numerals are partly used below.

FIG. 1 shows highly schematically an inventive furniture 1 in a use state with a hollow cuboid furniture body 2 and a displaceable in the furniture body 2 3. The furniture body 2 comprises two opposite vertical side walls 4 and 5, between which the drawer 3 via telescopic guide means or a first rail partial or full extension 6 and a second rail partial or full extension 7 from a inside the Furniture body 2 accommodated state in the horizontal direction from the furniture body 2 according to P1 can be pulled out and pushed in the opposite direction according to P2.

The screwed on the inside of the side wall 4 full rail extension 6 is opposite to the same vertical height to the screwed to the side wall 5 in FIG. 1 concealed rail partial or full extension 7, which is indicated by dashed lines.

In the furniture body 2 is above the drawer 3 another on rails-full extensions 8 and 9 correspondingly guided drawer accommodated in FIG. 1 not shown.

The drawer 3 has opposite drawer side walls 10, 11, which in each case comprises a hollow chamber frame constructed according to the invention with a decorative element 15 or 16. In addition, the drawer 3 comprises a front element 12, a rear wall 13 opposite thereto in the horizontal direction, and a horizontally extending drawer bottom 14 which extends toward or is connected to the drawer side walls 10, 11, the front element 12 and the rear wall 13.

In the FIGS. 2 to 7 is a first embodiment of a hollow chamber frame 17 according to the invention for a drawer such. B. the drawer 3 shown in more detail. In this case, a decorative element 19 in the Figures 2 and 3 only over a partial length of the hollow chamber frame 17 and in the FIGS. 4 to 7 formed over the entire length of the hollow chamber frame 17.

The hollow chamber frame 17 has a preferably constructed of a sheet material hollow frame body 18, on which the decorative element 19 is releasably attached. At the hollow chamber frame 17 is according to the Figures 2 . 3 and 5 a drawer bottom 20 and a drawer rear wall 21 of the associated drawer are present, the drawer bottom 20 and the drawer rear wall 21 are shown only partially or in section.

The frame body 18 is made of a multiply bent sheet metal section and has an aligned parallel to an outer wall 22 of the Zargenkörpers 18 inner wall 23, which is spaced over a thickness D of the Zargenkörpers 18 of the outer wall 22. Over the entire length L of the Zargenkörpers 18, the outer wall 22 and the inner wall 23 are connected at the top via a narrow strip-shaped web 24 in the useful state of the drawer preferably horizontal top. On the frame body 18 four in the lower region inwardly open angle sections 25 for receiving and supporting a longitudinal edge portion of the drawer bottom 20 are mounted or arranged. Furthermore, an attachment flange 26 for attaching the rear wall 21 is provided on the rear end side of the hollow frame body 18 (see FIG Fig. 4 ).

The decorative element 19 is preferably made of metal or as multiply bent sheet metal material and comprises a surface element 27 for covering the outer wall 22, a gripping portion 28 at the lower edge of the surface element 27 and a contact portion 29 at the upper edge of the surface element 27. The gripping portion 28 and the Anlageabschnitt 29 are preferably formed continuously over the length of the decorative element 19. The surface element 27 has in the illustrated embodiment, a closed planar outer and inner surface, and is rectangular in plan with parallel opposite vertical edges. A z. B. provided with regular or similar recesses surface element 27 is alternatively possible.

The surface element 27, the gripping portion 28 and the abutment portion 29 are preferably in one piece. In particular, the gripping portion 28 and the abutment portion 29 at the edge of the surface element 27 by bends 39 are present.

The connection of the decorative element 19 on the frame body 18 is shown in detail from the enlarged view FIGS. 6 and 7 seen. Accordingly, the gripping portion 28 surrounds a lower edge 30 of the outer wall 22 of the Zargenkörpers 18. The gripping portion 28 is formed on the surface element 27 inwardly projecting by two right-angled bends, so that a flat top open groove 31 is present, in which the lower edge 30 of engages above and is supported on a flat groove bottom 31a. The edge 30 of the outer wall 22 is configured in the illustrated embodiment by a bent over by 180 degrees material region and thus has a curved shape. The gripping portion 28 and the groove 31 are tuned so that the respective present edge design of the edge 30 of the outer wall 22 suitable for receiving in the groove 31 and thus a secure clasping and thus attachment of the decorative element 19 is ensured below the outer wall 22. The width of the groove 31 is designed in the embodiment shown so that a comparatively small horizontal play or a play parallel to the plane of the groove bottom 31 a between the edge 30 and the gripping portion 28 is possible. This serves in particular for tolerance compensation or for easier attachment of the decorative element 19 on the frame body 18 or on the lower frame body edge 30.

When the inner surface of the surface element 27 is flat, it is preferably at a minimum distance from the outside surface of the outer wall 22 or lies flat against it.

The groove 31 is preferably formed along the decorative element 19 throughout to accommodate the corresponding total or partial length of the lower edge 30, depending on whether the decorative element 19 covers the frame body 18 over the entire length or not.

The decorative element 19 is designed in such a way that all production tolerances of the frame body 18 that are relevant in practice can be tolerated, so that the decorative element 19 can always be fastened to the frame body 18 in a suitable manner and with sufficiently high connection quality. In addition to the shape of the decorative element 19 also contributes that the decorative element 19 has a comparatively small wall thickness and thus shows a certain elastic behavior, which in particular relates to the contact section 29, which also facilitates the manual attachment of the decorative element 19 on the frame body 18. In particular, the abutment portion 29 standing at an angle to the surface element 27 can bend slightly upwards and downwards around a connection region 38 to the surface element 27 or can pivot elastically in a slightly recoverable manner, which is shown in FIG FIG. 7 indicated by the double arrow P3. Is in the attachment of the decorative element 19 on the frame body 18, which is explained below, the contact portion 29 z. B. slightly bent up to come in the region of the web 24 in abutment, thus acts a bias by the elastic restoring behavior of the contact portion 29, which presses against the web 24 and thus substantially contributes to the attachment of the decorative element 19 on the frame body 18.

To attach the decorative element 19 on the frame body 18, the decorative element 19, wherein the gripping portion 28 is parallel to the edge 30 of the Zargenkörpers 18, slightly inclined, so that the plane of the surface element 27 relative to a z. B. vertical orientation of the outer wall 22 of the Zargenkörpers is inclined, wherein the abutment portion 29 is further away to the outer wall 22 as the lower gripping portion 28th

By manual movement of the decorative element 19 and the gripping portion 28 to the lower edge 30 of the Zargenkörpers 18, the groove 31 can now be threaded on the edge 30 and get in contact with this from below. The oblique orientation of the threaded at the edge 30 of the Zargenkörpers 18 Decorative element 19 is in FIG. 2 indicated, wherein the outline of the obliquely oriented decorative element 19 is dashed. With the contact of the groove bottom 31a at the edge 30, a pivot axis is generated about which the decorative element 19 in the next assembly step in the direction P4 (s. FIG. 2 ) is pivoted to the outer wall 22 while the contact portion 29 comes into abutment with the web 24 of the Zargenkörper 18. The contact section 29 can optionally click in at a slight bend upwards on the web 24 or snap it in automatically. The decorative element 19 is securely fixed at the bottom and top of the frame body 18 in the mounting position on the frame body 18, which is the FIGS. 6 and 7 demonstrate.

In contrast to the embodiment according to the FIGS. 8 to 10 the inside of the surface element 27 is flat over its entire surface and at least nearly parallel with the mounting position at a small distance b from the surface of the outer wall 22 of the frame body 18 (see FIG. FIG. 7 ). Even a flat concern of the inside of the surface element 27 on the outside surface of the outer wall 22 is not excluded, but this occurs only in exceptional cases or only in the rare case of limit at corresponding maximum tolerance values.

The details of the abutment contact of the abutment portion 29 in the region of the web 24 or in the embodiment shown in the region of an inner longitudinal edge 24a of the web 24, shows FIG. 7 , One of the inner side longitudinal edge 24a of the web 29 opposite parallel outside longitudinal edge 24b is to avoid jamming of the decorative element 19 on the web 24 without contact or without contact on the inside of the decorative element 19 and the abutment portion 29th

The contact section 29 has an inner side 33, which is planar over its substantial extent, wherein a narrow gap 32 is formed between the inner side 33 and the likewise flat outer surface of the web 24. The gap 32 has in the illustrated Embodiment in which a convex or inwardly bent abutment surface 34 of the abutment portion 29 in the region of the inside longitudinal edge 24a in abutment, a constant gap width. The partly straight and partly concave shape or contour of the contact surface 34 is suitably matched to the partially straight and partially convex shape or contour in the region of the longitudinal edge 24a, so that the contact surface 34 comes as far as possible in the region of the longitudinal edge 24a into abutment.

For spacing the abutment surface 34 from the inside 33, a shoulder 36 is formed on the underside on the abutment portion 29 between the abutment surface 34 and the inside 33.

An end face 37 of the abutment portion 29 facing away from a longitudinal edge of the abutment portion 29 or at the end facing away from the surface element 27 is preferably flat and flush or at least only comparatively very slightly protruding in the tenth of a millimeter range according to the dimension a in FIG FIG. 7 to the surface of the inner wall 23.

In abutting contact of the abutment portion 29 on the frame body 18 or on the web 24, a nose-like lower edge 37a of the end face 37 extends with its free end slightly in the downward direction, so that the free end of the edge 37a slightly or for example in the tenth of a millimeter range or by the measure c (s. FIG. 7 ) is lower than an upper side of the web 24. The nose-like edge 37a forms one end of the contact surface 34 and thus also contributes to the holding of the decorative element 19 on the web 24 of the Zargenkörpers 18 at.

With the edge 37 a hooking or a rear or encompassing of the contact portion 29 in the region of the longitudinal edge 24 a is realized. The engagement direction is based on the top of the web inward or downward. Alternatively, a suitable shaping or, for example, notches in the web 24 for engagement with matching in the form bearing surfaces 34 is not excluded.

With the pressing contact surface 34, a holding force for holding the decorative element 19 is provided against a force acting on the decorative element 19 tensile force, which is effective on the contact surface towards the surface element 27 out, which the fuse against pulling away the decorative element 19 perpendicular to the outer wall 22 of Zargenkörpers 18 and / or opposite to the pivoting direction P4 is used.

In practice, a to in FIG. 7 shown slightly different picture. Accordingly, the gap 32 can also be uniformly variable in its width over the extension between the outside longitudinal edge 24b and the inside longitudinal edge 24a, or the contact section 29 can be slightly inclined to the top side of the web 24. When the height H of the frame body 18 (see FIG. FIG. 2 ) or the height H between the edge 30 and the web 24 is only slightly larger than in FIG. 7 is based, then with attached decorative element 19 of the contact portion 29 is slightly elastically deflected upward, in abutting contact of the contact surface 34 in the region of the longitudinal edge 24a. Thus, the gap 32 tapers slightly from the abutment surface 34 in the direction of the longitudinal edge 24b. In this case, the flat inner side 33 of the abutment portion 29 optionally in the area of the outer longitudinal edge 24 b on the upper side come into contact with the web 24th

The Figures 6a and 6b show very schematically from the side of the lower part of the decorative element 19 in the cutout, each with a variant of the gripping portion 28th

According to FIG. 6a is an elastic O-ring cord 43 inserted into the groove 30 for height compensation.

To FIG. 6b a resilient arm 44 bent back towards the inside of the surface element is formed, which has the groove 30 at its front end.
