The invention is based on the object of providing an improved hollow profile element for use as a transverse railing and / or longitudinal railing of a piece of furniture, in particular a hollow profile element which enables an improved attachment of lighting means to a drawer frame and / or an improved lighting of the drawer frame.

This object is achieved by the features of claim 1, claim 10 and claim 11.

Advantageous and expedient developments of the invention are mentioned in the dependent claims.

The invention relates to a hollow profile element for use as a transverse and / or longitudinal railing of a piece of furniture, the hollow profile element having a cavity, the cavity extending in a longitudinal extension of the hollow profile element, the hollow profile element having openings on opposite and spaced-apart end faces, the Openings of the end faces are present as openings of the cavity, the cavity being enclosed by a lower, an upper and two side wall elements of the hollow profile element, the lower, the upper and the two side wall elements extending in the longitudinal extension of the hollow profile element, the hollow profile element has a recess on the lower wall element, the recess, in particular the lower wall element, being formed from opposing and spaced-apart side elements and a support element, the side elements and the support element i Extending the longitudinal extension of the hollow profile element, the support element connecting the side elements to one another, the support element is present recessed on the hollow profile element, wherein the support element has light-permeable light-permeable elements, so that starting from the cavity of the hollow-profile element, in particular visible light can exit the hollow-profile element through the light-permeable elements. The hollow profile element according to the invention enables lighting means to be attached to a drawer frame and / or improved lighting of the drawer frame.

The hollow profile element preferably comprises a single cavity. The side wall elements are advantageously spaced from one another and formed opposite one another. The upper wall element and the lower wall element are also spaced apart from one another and are present opposite one another. The side wall element connects, for example, the upper wall element with the lower wall element.

The recess is, for example, U-shaped, for example in the form of a U-shaped groove. For example, the lower wall element is completely formed by the recess. The hollow profile element advantageously comprises a single recess. The recess preferably extends, in particular the side element and the support element of the recess, extend over more than half of a length of the hollow profile element in the longitudinal extension of the hollow profile element. The recess advantageously extends over at least 50%, at least 75%, at least 80%, at least 90% or at least 95% of the length of the hollow profile element in the longitudinal extension of the hollow profile element. For example, the recess extends, in particular the side element and the support element, extend over an entire length of the hollow profile element in the longitudinal extension of the hollow profile element. The recess is designed for this purpose, for example, in the arranged state of the hollow profile element a drawer frame, in particular on a drawer, to arrange a frame wall of the drawer frame, for example to be accommodated between the side elements. For example, in the arranged state of the hollow profile element on the frame wall, the support element is present in contact with the frame wall, in particular on an upper side of the frame wall.

Advantageously, the length of the hollow profile element extends between 200mm and 1400mm, e.g. between 220mm and 1300mm, in particular between 250mm and 1150mm. The hollow profile element is, for example, 200mm, 220mm, 250mm, 300mm, 400mm, 1000mm, 1150mm, 1200mm, 1300mm or 1400mm long, viewed in the longitudinal direction.

The hollow profile element is, for example, between 6mm and 20mm, between 6mm and 18mm, between 6mm and 16mm, between 6mm and 12mm or between 6mm and 10mm wide. The width of the hollow profile element is, for example, 6mm, 6.5mm, 7mm, 7.5mm, 8.5mm, 9mm, 9.5mm, 10mm, 11mm, 12mm, 16mm, 18mm or 20mm, in particular 8mm. The width of the hollow profile element advantageously extends from an outside of a first lateral wall element to an outside of the further lateral wall element. The outer sides of the side wall elements are present on the side wall element facing away from the cavity, for example. The side wall elements include, for example, inner sides which each form a delimitation of the cavity. The inside of a wall element is advantageously spaced apart from and opposite to the outside of the wall element. The inside and the outside of the wall element are preferably spaced apart from one another over a wall thickness of the wall element.

The hollow profile element is for example between 5mm and 30mm, between 10mm and 25mm, between 12mm and 25mm, between 12mm and 20mm, between 14mm and 20mm or between 16mm and 18mm high. The height of the hollow profile element is, for example, 5mm, 10mm, 11mm, 12mm, 14mm, 18mm, 20mm, 25mm or 30mm, in particular 16mm.

A wall thickness of the upper wall element, a side wall element, the lower wall element, the side elements and / or the support element is between 0.3 mm and 3 mm, for example. The wall thickness is, for example, between 0.5mm and 2.5mm, between 0.6mm and 2mm, between 0.8mm and 1.5mm. The upper wall element, a side wall element, the lower wall element, the side element and / or the support element has, for example, a wall thickness of 0.3mm, 0.4mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.2mm, 1.4mm, 1.6mm, 2mm, especially 0.5mm.

A length of the cavity advantageously extends over a complete length of the hollow profile element. The length of the cavity corresponds, for example, to 50%, 60%, 70%, 80% or 90% of the length of the hollow profile element. The cavity extends, for example, over a width between 5 mm and 19 mm, between 5 mm and 14 mm, between 5 mm and 12 mm or between 5 mm and 10 mm. The width of the cavity is, for example, 5mm, 5.5mm, 6mm, 6.5mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, 12mm, 14mm or 19mm, in particular 7mm. The cavity extends, for example, over a height between 6 mm and 25 mm, between 6 mm and 20 mm or between 8 mm and 14 mm. The height of the cavity is, for example, 6mm, 7mm, 8mm, 9mm, 10mm, 12mm, 13mm, 14mm, 20mm or 25mm, in particular 11mm. A ratio of height to width of the cavity is, for example, in a range between 2 to 1.2, between 1.8 to 1.2, between 1.8 to 1.3, between 1.8 to 1.4 or between 1.7 to 1.4, in particular between 1.6 to 1.5. The ratio of height to width of the cavity is for example 1.2, 1.3, 1.4, 1.5, 1.55, 1.56, 1.58, 1.6, 1.7, 1.8 or 2, especially 1.57.

It is also proposed that a light strip is present in the cavity. The light strip is available, for example, as a light band. For example, the light bar is designed as an LED light bar, e.g. as an LED strip. The frame wall and / or a drawer interior can be illuminated by the light strip, in particular in the case of a light-conducting frame wall.

It also proves to be advantageous that assembly elements for attaching the light strip are formed in the cavity. For example, a mounting element is designed like a rail or clamp, so that the light strip can be pushed into the mounting element. For example, the mounting element is designed as a rail or bracket. For example, the mounting element is designed in such a way that the light strip can be clamped or clipped onto the mounting element. It is also conceivable that the mounting element comprises an adhesive member so that the light strip can be glued to the mounting element. It is also conceivable that the mounting element is present in a thermally conductive manner. For example, the mounting element is made of metal, for example copper, sheet metal or aluminum. As a result, in the arranged state of the light strip on the hollow profile element, heat dissipation from the light strip is improved.

The cavity is advantageously present free of material except for the mounting elements and / or the light strip, e.g. as a material-free hollow volume.

It is also proposed that the hollow profile element is designed as a continuously cast element. In particular in this case it is advantageous that the side element of the recess as a component of a side wall element is present. For example, in this case in particular, a side element and a wall element are formed in one piece. As a result, the hollow profile element can be produced comparatively inexpensively.

The hollow profile element is preferably present over at least 20%, at least 50% or at least 60% of its length along a circumference around the longitudinal extent, in particular completely closed.

In an advantageous embodiment, the hollow profile element is designed as a folded and / or folded element. The hollow profile element is advantageously formed from a single bent and / or folded piece of metal, for example sheet metal, in particular strip steel. The hollow profile element is preferably brought into the final shape during production from a coherent flat material by forming such as cold forming. As a result, the hollow profile element can be produced comparatively inexpensively. Ends of the flat material formed as a hollow profile element are, for example, connected to one another. The ends of the reshaped flat material are, for example, welded, glued or riveted or toxed to one another.

For example, a side element of the recess is connected to a side wall element via a bent section. For example, the side wall element merges into the side element via the bent section. For example, the side element of the recess is bent or edged so far over the bent portion towards the side wall element that the side element and the side wall element are present running approximately parallel to one another.

According to the invention are the upper wall element, the side Wall elements, the side elements and the support element are integrally formed. For example, a side element and a side wall element enclose a bending angle in a range between 45 angular degrees and 180 angular degrees.

In addition, it is advantageous that the hollow profile element is made of plastic and / or metal.

It also proves to be advantageous that the light transmission elements are present as passage openings. For example, the light transmission elements are designed as cylindrical, oval, rectangular and / or round holes. For example, the light transmission elements are punched out of the remaining material of the hollow profile element.

It is also conceivable that there are through openings on the support element, e.g. in the form of cylindrical, oval, rectangular and / or round holes and that light transmission elements are inserted into the holes. For example, the light transmission elements are designed in the form of color filters, e.g. as colored elements, e.g. as colored glass or plastic elements. As a result, the frame wall and / or the interior of the drawer can be illuminated in different colors, in particular in sections, when the hollow profile element is in the arranged state.

In addition, it is advantageous that the support element of the cutout is present exclusively in sections so as to be transparent to, in particular, visible light due to the light transmission elements. It is also conceivable that the support element of the recess is present continuously through the light-permeable elements in the longitudinal extent of the hollow profile element and is transparent to, in particular, visible light.

For example, the light transmission elements are connected to one another.

In an advantageous variant of the hollow profile element, the light transmission elements are provided on the support element at a distance from one another. The light transmission elements are preferably spaced apart from one another over a distance between 10 mm and 30 mm. A distance between the light transmission elements, especially seen in the direction of the longitudinal extension of the hollow profile element, is, for example, 10mm, 15mm, 25mm or 30mm, in particular 20mm.

An advantageous modification of the invention forms a railing of a drawer comprising a hollow profile element according to one of the preceding variants.

Another advantageous embodiment of the invention is a piece of furniture with a railing as described above, the hollow profile element of the railing with the lower wall element being placed on a frame wall of a frame of the piece of furniture, in particular a drawer.

The hollow profile element of the railing is advantageously clamped and / or clipped onto the frame wall.

For example, the support element and / or the side elements are in direct contact with the frame wall when placed on the frame wall. The side elements of the hollow profile element preferably encompass the frame wall in the arranged state. In the arranged state, the hollow profile element advantageously encloses the upper side of the frame wall, in particular completely. For example, in the arranged state, the hollow profile element encloses the upper side of the frame wall with the side elements and the support element.

The frame wall is, for example, made transparent, for example made of glass or plastic. It is also conceivable that the frame wall is designed to be light-guiding in sections.

The hollow profile element 1 is preferably formed from a folded or bent flat material 16. End sections 17, 18 of the flat material 16 are advantageously connected to one another in a non-detachable manner. For example, the end sections 17, 18 are welded along a contact area 19 at which the end sections 17, 18, for example, rest against one another. For example, have the upper wall element 2, the side wall elements 3, 4, the Side elements 11, 12 and / or the support element 13 have the same wall thickness d.

The cavity 14 has a height h and a width b. The width b of the cavity 14 extends, for example, between inner surfaces 20, 21 of the side wall elements 3, 4. The height h of the cavity 14 extends, for example, from an inner surface 22 of the upper wall element 2 to an inner surface 23 of the support element 13.
