Description

The invention relates to a support structure element for support frames of table furniture and similar pieces of furniture, consisting of a support frame and possibly inside the Support frame trellis-shaped lattice bars or ribs. The invention further relates to a method ren for the production of such support structure elements.

The supports of table furniture include u. a. Leg bag zen, support columns and side walls as well as cross beams, cross cantilevers and trusses, the task of Tragla most to be recorded and transferred to the ground. To one to achieve a construction that is as light and transparent as possible, has already been proposed supporting structure elements this type of gray cast iron and die-cast aluminum len. One finds such supporting structure elements for example wise at support points of old sewing machines. The Her Position of castings is very material and time consuming and therefore for the mass production of Racks unsuitable for table furniture. Except there of the known supporting structure elements the same profile shape without oversizing Adapt individual load requirements.

Proceeding from this, the object of the invention grunde, a supporting structure element for supporting frames from To develop table furniture and similar pieces of furniture, which is a lightweight construction and yet a high load  ability and torsional stiffness. A another task is the development of a ge suitable method for producing the fiction moderate structural elements.

To solve this problem, the in the patent say 1 or 32 features proposed. Further advantageous refinements and developments gene of the invention result from the dependent on sayings.

The invention is based on the idea that above all relatively large volume in the aluminum extrusion process and versatile hollow section rails can be produced are that with simple means in short open cell disc-like sections of high strength and twist stiffness can be sawn, which follows which are called profile washers. Accordingly proposed according to the invention, the support structure ment as an open-cell profile disc that from one with axially parallel profile and Hollow chamber profile rail provided is separated transversely to its longitudinal axis, the outer profile wall of the profile plate, the support frame and the inner hollow chamber walls the lattice webs of the support form structural element. The hollow section rail is useful as an extruded aluminum profile educated.

In order to easily assemble the supporting structure elements  enable is in the field of profile and / or hollow Chamber walls of the profile disc at least one axially going insert or screw channel formed can already be preformed in the extrusion process. There may be another improvement in this regard be achieved by that on the profile wall of the profile rail at least one protruding outside preferably a larger wall thickness than the profile wall having, trained as a mounting or support element The profile approach is formed, with a group pe of several parallel to each other, by one each edge-open gap separated profile approaches can be provided. Profile approaches of this type are for example as a base for the adjustment feet or as mounting structures for stable fastening frame structures used.

A further easing of assembly is achieved by that the profile disc on the outside at least a profile wall section as a surface toothing has formed axial groove grid, wherein purpose moderately at least one on the side of the surface toothing tion rib-like protruding guide wall is provided can be used to target and accommodate a two ten, with a complementary surface serration seen component is used.

It can further facilitate assembly in the profile plate be an edge in the area of the profile wall towards the outside open cylindrical cavity be molded while  at the free end of one over the profile wall of another protruding rib into the part cylindrical hollow chamber insertable and with this by means of a tensioning device, preferably edge-open expansion sleeve can be formed. This measure take allow a simple yet effective full non-positive and positive connection, free of play between two profile washers.

A high variability when assembling different Profile disks to a support frame can be achieved be that the profiled washers essentially one triangular outline with two an acute angle other including long triangular sides and one have a short triangle side. The short triangular sides serve primarily for mutual connection of the profile washers, while the long triangular sides serve primarily for load support and power transmission.

The profile disks of a first group, above all are suitable for leg supports, have the outline shape an acute isosceles triangle. The hollow chamber walls expediently run parallel there to the short side of the triangle and thus delimit from the common triangle tip seen from similar triangles. At the top of the triangle is a useful as a base Profile designed to accommodate an adjustable foot molded on approach.

The profile disks of another group have a purpose  moderately the shape of a right triangle on, with the cavity walls perpendicular to the hypotenuse of the triangle. These profile washers are useful as cross brackets or cross beams a support frame to accommodate a load forms. The surface gearing is expedient the outside of the short side of the triangle in this area a connection to a white teres structural element, for example on a traverse, to accomplish.

Another variant provides that the profile disc the shape of an elongated rectangle points and thus for example as a support column or as Cross member of a support frame comes into consideration.

The profile disk, which is preferably triangular in outline useful as a horizontal cell leg support for a Table frame trained. The term "horizontal cell" means here that the disc axis, that of the longitudinal axis of the original hollow section rail speaks, with the table frame standing on the floor is aligned horizontally.

Another variant provides that the profile disc as a horizontal or vertical cell cross-arm or Cross member to accommodate a preferably as a table plate-shaped load capacity is formed. "Verti limestone "here means that the profile disks axis in the intended arrangement of the trolley  stells is aligned vertically.

Another application variant provides that the Pro Fil disc as a horizontal cell support column or sides cheek, preferably designed for a table frame is. Finally, the profile disc can also be used as a hori zontal- or vertical cell foot extension preferably be designed for a table frame with L-foot.

The thickness of those to be separated from the hollow profile rail Profile washer should be selected at least so that benen dimensions of the profile and hollow chamber walls sufficient strength for the application and Stiffness is guaranteed. The bigger the forces to be absorbed, the greater the thickness the profile disc to choose. With table furniture it has turned out to be particularly advantageous if the profile washer is designed in its wall thicknesses so that their axial thickness less than a third, preferably less less than a tenth of the largest profile disc knife is.

The profile disc, primarily made of aluminum can be provided with a surface coating, preferably anodized, painted or powder-coated, whereby to achieve a special decorative effect ts the cut edges after the surface coating sanded while exposing the base material can. Next, the profile disc can at least one of their open cell broadsides with one  decorative and protective cover.

To manufacture the support frame, two, preference show the shape of an isosceles triangle showing leg pointing downwards support in pairs, including a downward open an acute angle or (already in the course of Manufacture of the hollow section rail) in one piece be connected to each other.

It is also possible that one of the triangular legs support and / or the rectangular support column on the one hand and one of the cross beams or cross arms on the other hand detachable or (already in the course of the manufacture of the hollow chamber profile rail) connected in one piece will. To achieve a particularly favorable Abla The hollow chamber walls become power or power transmission of the cross-arm, triangular in outline, expediently parallel lel to the adjacent long triangle side of the legrest and / or the hollow walls of the leg support in parallel to the adjacent long triangular side of the cross-arm aligned.

Furthermore, it has as the assembly of the support frame Proven useful when two cross-arms or cross carriers in pairs in mirror-inverted alignment with narrow sides facing each other and / or are connected to the leg supports. Are there at least two spaced apart from each other arranged and aligned parallel to each other  ger or cross boom pairs by means of a preferably trained as an elongated hollow section bar Traverse connected together. To make one the crossbar has a positive connection at least one outer surface one for interlocking the surface adjacent profile disc complementary, as grooves grid formed surface gearing.

With the side surface serrations on the crossbar can a simple height adjustment of a table top on the table frame through the additional use of preferably designed as open-cell profile disks supporting structure elements for the table top be light that on a profile outer surface one for Surface toothing of the crossmember complementary, as grooves raster trained surface gearing as well as a cross to the elongated slot for the penetration a fastening screw and the height adjustable Have attachment to the traverse.

The method according to the invention for the production of support sees structural elements of the type mentioned before that in an extrusion or extrusion process drive manufactured hollow section rail under Bil the support structure elements transverse to their longitudinal axis divided into individual open cell profiles, ins special sawn or cut. The axial Thickness of the pro to be separated from the hollow profile rail fil disc can be made according to the requirements of her forces or loads.  

The profile disks can be coated with a surface tion, preferably anodized, painted or be powder-coated and, if necessary, on their cutting channel then be sanded decoratively. The Profile washers are designed so that under Bil Extension of a support frame in pairs with each other and / or connected to other profile disks, preferably ver can be screwed or clamped.
