Definitions

• the invention relates to a rail pull-out or a telescopic pull-out for the horizontal or vertical pull-out of an extendable element, in particular a food support for a cooking appliance.
• An object of the invention is to improve the stability of a known rail extension or telescopic extension.
• the U-shaped additional rails are inserted inside or outside of existing sheet metal profiles by mutually displaceable outer or slide rails and connected to them.
• the outer dimensions of the rail or telescopic pull-out remain the same, but the stability of the rails is significantly increased.
• the additional rails can be welded, riveted, screwed or glued to the base rails. These connection points can either be punctiform (e.g. welding or adhesive points) or linear.
• the rails are typically made of bent sheet steel.
• the inner additional rail can in particular be designed as a U-profile or as a hollow profile, for example as a D-profile or the like.
• a telescopic pull-out is formed from at least two identical rail pull-outs, which are joined together with the backs of their additional rails.
• FIG. 1 shows a cooking appliance with a horizontal rail extension according to the invention
• FIGS. 2 and 3 each show a cooking appliance with a vertical rail extension
• FIGS. 4 and 5 each show a schematic detailed view of two alternative variants of the rail extension according to the invention
• FIG. 6 shows a schematic detailed view of a telescopic extension according to the invention
• Figure 7 is a schematic diagram of an extendable element of a telescopic pull-out.
• Figure 1 shows a cooking device 2 in a conventional design with a front door 23 in the form of a flap that can be opened downwards.
• Rail extensions 4 are provided on the side walls of a cooking chamber 22, which allow horizontal extension of an extendable element 26, preferably a food support 28 or the like.
• the rail pull-outs 4 are each designed as a so-called partial pull-out, in which a short section of the food support 28 remains within the cooking space 22.
• a longer extension path of the food support can be achieved by means of a so-called full extension, which has telescopic extensions instead of simply pull-out rail extensions. This variant of an extract is described in more detail with reference to FIGS. 6 and 7.
• FIGS. 2 and 3 each show an alternative embodiment of a cooking appliance 2, which has a door 23 on an underside 24 of an oven housing 21, which can be displaced vertically downwards and thus makes access to a support 28 accessible for food to be cooked (see FIG. 3 ).
• the downwardly extendable element 26 can also be designed to be extendable by means of a telescopic extension, as is described in more detail in FIGS. 6 and 7.
• FIG. 4 shows a top view of a first variant of a rail pull-out 4 according to the invention in a schematic detailed view.
• a U-shaped outer rail 41 is fastened to a side wall or another fastening point of a furnace housing 21.
• the outer rail 41 is with a base 42 of its U-profile by means of screw, adhesive, rivet and / or welded connection to the furnace housing 21.
• the legs 43 of the U-profile of the outer rail 41 are designed as running surfaces for rolling elements or balls 48 of a rolling bearing 47. They therefore have a slightly curved contour.
• an additional outer rail 49 is provided within its U profile, the legs 51 of which are connected to the inner sides of the legs 43 of the outer rail 41, and the base 50 of which is connected to the base 42 of the outer rail 41.
• These connections can optionally be designed as welded, adhesive, riveted and / or screwed connections.
• An increased torsional stiffness can be achieved in that a number of connection points are provided in cross section and not only, for example, on the base 42 of the outer rail 41 between the base 50 of the additional outer rail 49.
• roller bodies 48 of the roller bearing 47 are supported on the inside on the legs 43 of the outer rail 41, they guide a slide rail 44 on the outside, the two legs 46 of which are each slightly curved inwards and in this way for fixing the balls 48 to their intended ones careers.
• a base 45 of the slide rail 44 is connected to a base 53 of an additional rail 52, the legs 54 of which abut or are connected to the legs 46 of the slide rail.
• These connections can also be configured as welded, adhesive, riveted and / or screwed connections.
• the additional rail 52 stiffens the slide rail 44 and prevents it from twisting when the rail pull-out 4 is pulled out.
• the additional outer rail 49 stiffens and stabilizes the outer rail 41.
• the balls or rolling elements 48 are preferably guided in a cage 55, which ensures that the balls are evenly spaced from one another.
• the roller deposit can have grease lubrication that is resistant to the temperatures in the cooking space. If the stove is also operated temporarily in a pyrolysis mode, such grease lubrication is unsuitable because it cannot withstand the typical pyrolysis temperatures of approx. 500 ° C.
• rolling elements and / or raceways made of ceramic or with a ceramic coating can be used.
• FIG. 5 shows a second variant of the rail pull-out 4 according to the invention in a schematic detailed view.
• the outer rail 4 is connected to a rear side 56 of its D-profile by means of screw, adhesive, rivet and / or welded connections to the furnace housing 21.
• the legs 43 of the D-profile of the outer rail 41 are designed as running surfaces for balls 48 of the roller bearing 47, as in the first variant, and therefore have a slightly concave profile.
• the outer rail 41 is very stiff against torsion and bending due to its closed profile.
• the closed profile is achieved by a base 50 connecting the legs 43, which in this variant corresponds to the additional outer rail 49 according to the first variant.
• FIG. 6 shows a detailed view of a telescopic extension 6, which is essentially constructed from two interconnected rail extensions 4 according to FIG. 4.
• two additional rails 52 are connected to one another with the rear sides of their bases 53, so that the slide rails 44 can be moved longitudinally over the left part of the telescopic pull-out 56 relative to the furnace housing 21 and the right part of the telescopic pull-out 6 with the extendable element 26 can be moved longitudinally with respect to the two slide rails 44 ,
• the rest of the structure corresponds to that of the rail extension 4 according to FIG. 4.
• a telescopic extension with combined rail extensions according to the second variant (FIG. 5) can be implemented.
• a combination of both variants in a telescopic extension can also be useful.
• FIG. 7 illustrates in a perspective schematic representation an extended telescopic extension 6, in which the outer rail 41 is fastened to the furnace housing 21.
• the additional rails 52 which are shifted downward relative to the outer rail 41, in turn hold the additional outer rail 49 fastened thereon, to which the extendable element 26 is fastened.
• the two arrows show this load.
• a single telescopic pull-out or rail pull-out can be provided to support and move a food support.
• two parallel pull-outs are often provided, which are arranged on both sides of the door and ensure better guidance.
