Definitions

  • the invention relates according to the preambles of claim 1 an extracting device, in particular for an oven.
  • Such a pull-out device of a baking oven is known.
  • the guide rail is fastened to a support grid which is detachably attached to a side wall of the cooking chamber for cleaning.
  • the cooperating locking means are otherwise connected to each other via several components or guided to each other. These comprise lying outside the extractor larger components of the oven with relatively large dimensional tolerances, such as the support grid and / or the wall of the cooking chamber and their releasable connection means. Furthermore, not insignificant thermal expansions occur during operation on these components. These influences require to compensate for a relatively large locking device with large spring travel in order to achieve a safe, not too different strong detents.
  • the invention has for its object to provide a pullout device according to the preamble of claim 1, which avoids or mitigates the disadvantages of the prior art and is particularly easy to use and reliable in operation with low production costs.
  • This object is achieved by the combination of features of claim 1.
  • This solution has the advantage that adjacent to the fixation of the pull-out, with tight tolerances to each other guided components are fixed together. This allows structurally small, simple, cost-effective fixing devices that can be protected against contamination and favorable in terms of form design view, concealed under or inside of rails of the pull-out device can be arranged. Also, the influence of thermal expansion during operation is low. Furthermore, it is advantageous that the fixing device directly forms part of the extraction device and is arranged on or in this, since the extraction device usually from another production, usually one on the production of WälzSystem installeden in larger series specialized supplier company which is geared to high precision and can deliver this cost-effectively.
  • the fixing function prevents uncontrolled running away of the running rail, whereby the placement of the object to be supported, e.g. a food support and its loading and unloading easier and thus safer.
  • the extraction device is preferably installed in a housing space. When used in an oven, the risk of burns for the user is considerably reduced.
  • pulse-out device is here generally meant a displacement device, which is not intended only for a housing installation and which can also be driven in various ways for displacement. It can, as also explained in more detail below, have more than two rails and two or more roller body holders for a larger extension length.
  • the Wälzoasahalter is preferably a cage with fixed therein windows, in each of which a rolling element is guided, which can cooperate with two mutually rolling rails.
  • the rails usually roll together when displaced.
  • the fixing device is expediently designed so that the driving force to be released in the direction of travel is less than that required for the sliding displacement of the rails relative to one another at, for example, by a pollution blocked rolling elements.
  • the releasable fixation can be achieved by a form-locking connection such as a latching connection and / or by frictional engagement in at least one position, e.g. in the end positions, fully extended and / or retracted and possibly in any position.
  • the fixing device has a latching device, which locks the Wälz manipulatehalter with the rail, including the rail and the Wälzianuhalter preferably cooperating locking means.
  • a latching device which locks the Wälz phenomenahalter with the rail, including the rail and the Wälzianuhalter preferably cooperating locking means.
  • an end edge of a rail or of the rolling body holder can also simply serve as a latching means.
  • one of the locking means is elastically yielding.
  • the WälzSystem and / or the rail may comprise an elastic material and the resilient locking means may be formed thereon in the form of a spring tongue.
  • the dimensional tolerance chain of the guide to each other of the latchable components or the latching means comprises only a few members, so that can not build in the production of very different fits of the locking devices with different strong detent. This allows a reliable detent even with small spring travel of a few tenths, for example three-tenths of a millimeter.
  • the rolling element holder has a tongue-shaped projection projecting in one of its directions of travel. This can form a start-up approach and be inclined toward its free end slightly away from the adjacent rail. Further, it may comprise the locking means of the rolling body holder, e.g. in the form of a latching lug, which can be designed to increase the elasticity of a spring tongue which is stamped free in this approach. The approach may be formed in one piece with the rest of WälzSystem particular of an elastic material such as spring steel.
  • the tongue-shaped projection may comprise an elastic material and on the rest of the rolling body holder e.g. be attached by a snap, plug, or Toxthetic. The rolling element holder can then be made of another, e.g. cost or sliding guide moderately cheaper material and / or be modified from a cheaper high-volume part.
  • the running rail has, according to a preferred embodiment, a stop element attached thereto for the object to be supported, for. B. as a limiting element of the support length.
  • This stop element may comprise the locking means of the running rail.
  • the stop element may extend through an opening of the track rail and on its side facing the WälzArchitecthalter page a mounting head, e.g. have a rivet head, which forms the locking means without additional effort.
  • the fixing device may also have a braking device in addition or as a single fixing means.
  • This can have a brake element entrained by the rolling body holder, for example a leaf spring.
  • the brake element can accumulate on a projecting into its orbit elevation ie a projecting track portion in a not cooperating with the rolling elements of the rail.
  • the braking device can grind defined in all extension positions on the rail and thus sufficiently fix the pull-out device in any positions of the pull-out path for a comfortable operation.
  • a sliding element is suitably arranged between the Wälz Eisenhalter and at least one of the rails, which cooperate with the rolling elements.
  • This serves as an additional guide means of the rolling element holder, which slides or floats during the process of extracting the device with play and displacements i. the play of WälzSystems transversely to its direction of travel is limited to a minimum, secures its centering and is supported during the fixation, acting transversely to the longitudinal direction forces and tilting moments.
  • the sliding element is preferably arranged on the rolling body holder, e.g. formed by embossing.
  • a plurality of sliding elements which may be arranged at least partially on the rolling body holder.
  • a movable intermediate rail can be arranged to expand the maximum displacement movement, which cooperates with the rolling elements of two Wälz redesignhalter, wherein by means of fixing each Wälz redesignhalter on one of the rails, with its rolling elements interact can be fixed.
  • FIGS. 1 to 4 show a household oven 12 with a device housing 13 with a front upper control panel 14 and a cooking chamber 16 arranged underneath. On the side walls of the cooking chamber, of which only the right side wall 18 can be seen, support grid 20 are detachably attached for cleaning purposes. At the in Fig.1 shown oven 12 is a fold-down front door omitted to give full insight into the cooking chamber 16.
  • the support grids 20 each have a front vertical post 22 and a rear vertical post 24. These are connected by a plurality of slightly curved inwardly into the cooking chamber 16 horizontal guide rods 26 with each other, can be pushed onto the food support, not shown, such as baking trays or gratings. In the middle height of the cooking chamber 16, the vertical posts 22 and 24 are connected by a horizontal pull-out device 28. In this and one, not shown, similar extraction device on the support grid on the other side wall, a food support, for example, a grate or a baking sheet can be placed and is carried on and retracted thereon.
  • the pull-out device 28 has, as in particular in cross section in FIG Fig.2 It can be seen a nest of three nested rails, namely an inner guide rail 30 with a guide head 38, a surrounding this, C-shaped, downwardly open outer rail 32 and a running therebetween, C-shaped, downwardly open Wälzoasahalter 34.
  • the guide rail 30 and the track 32 extend over most of the depth of the cooking chamber 16 and the Wälz stresseshalter 34 extends over about a quarter to a third of its length.
  • the guide rail 30 protrudes with a vertical web 31 out of the C-profiles down and is attached by an adjoining, to the side wall 18 of the cooking chamber 16 toward bent attachment strip 36 by spot welds 37 on the vertical columns 22 and 24 of the support grid 20.
  • the running rail 32 is guided on the guide head 38 of the guide rail 30 by three rows of rolling elements 40 running between them. These include in a row four upper cylindrical rollers 42 which roll on a top wall 59 of the guide head 38 and on the underside of the web of the C-profile forming top wall 44 of the track 32, and four inner balls 46 and four outer balls 48 each in a series that roll in ball grooves at the bottom of the head 38 and lower end legs 50 and 52 of the track rail 32. All rolling elements 40 are in a known manner rollable in openings or windows of Wälzèves 34, which may also be referred to as a cage, supported or guided at intervals from each other.
  • the Wälzeniahalter 34 has a top wall 54 at the spaced apart, by expression up two sliding elements 56 for sliding interaction with play with the underside of the top wall 44 of the track rail 32 and by downwards two sliding elements 58 for cooperation with play with the top wall 59th of the guide head 38 are formed. These sliding elements 56 and 58 serve to secure the centering of the Wälz moments 34 and can be supported on the rails when latching on these forces acting or tilting moments.
  • the rolling element holder 34 is made of spring steel. His, the web of the C-profile performing top wall 54 is extended to form a fixing device in the form of a latching device 59 to the rear with a slightly backwards, down angled tongue-shaped approach lug 60, as in the Figures 3 and 4 you can see.
  • a forwardly projecting spring tongue 64 is punched free by a U-shaped cutout 62.
  • a roof-shaped upwardly projecting locking lug 66 pronounced to form an elastically resilient latching means of Wälzèves 34.
  • Near the rear end of the rail 32 has this in its top wall 44 has an opening 67.
  • Stop element 68 in the form of a cylindrical bolt as a rear stop for a food support, not shown, such as a baking tray or a grid is inserted with a reduced lower end portion 70 through the opening 67 and 44 at the bottom of the top wall by a tumbled, about attached spherical cap-shaped rivet head 72. This forms a locking means of the track.
  • the WälzConsequentlyhalter 34 moves at shifts half as fast as the slide rail 32.
  • fully extended position has the locking means in the form of the rivet head 72 when extending the latch nose 66 sliding under elastic deflection of the spring tongue 64, to the right in Figure 3 , run over and is engaged in front of this to secure this position of the slide rail 32.
  • the rivet head 72 pushes the latching nose 66 back down and passes over them again, whereby the latching is released and the running rail 32 can be moved freely rolling with the food support carried by it.
  • a locking means of a latching device at the front end portion of the WälzSystems cooperate with a locking means at the front end portion of the guide rail, for example in the form of an expression or a rivet head.
  • a stamping on the place of the rivet head expression may also be slightly longer, so that no longer engages the formation of a braking device resiliently resilient element of the fixing but runs up on this elevated rail area and clamped to fix it with friction.
  • the guide rail 82 is connected by means of mounting brackets 36 by spot welding fixed to the vertical columns 22 and 24 and except for these mounting bracket 86 and the missing pin 68 structurally identical to the rail 32.
  • the lower WälzSystem 84 is also latched in the fully extended position of the pullout and Although by means of a locking device, not shown, with the lower guide rail 82.
  • the latching device can in the following on the basis of Fig. 5 correspond, wherein an opening serving as a locking means is then formed in the lower guide rail 82.
  • Fig. 5 shows a modified extension device 528 with a modified locking device 559.
  • a rolling on a guide rail 530 running rail 532 has a latching means in its top wall 544 an opening 572.
  • a transverse, roof-like unfolded leaf spring 564 is inserted between the guide rail 530 and a rolling element below 534 , Their rooftop acts as a detent 566 latching with the aperture 572 together and forms a locking means of the rolling element 534 in the central region of the longitudinal extent thereof.
  • the leaf spring 564 engages with a downwardly angled foot 565 permanently in an opening of the Wälz emotionshalters to be in driving engagement therewith.
  • This latching device 559 brakes in the unlocked state by a slight grinding of the locking lug 566 on the running rail 532 slightly the movements of the Auzugs worn regardless of the load, which is worn rolling. This can be advantageous to avoid too light, unwanted shifts in intermediate positions.
  • the running rail of the embodiment according to Fig. 5 a cooperating with the latching nose 566 opening or embossing have appropriate location.
  • a spring tongue free-punched in a top wall of a rolling element carrier of elastic material can also be used.
  • WälzSystem can also be dispensed with an opening of the rail and a permanently grinding on the rail, defined slightly braking spring on Wälzoasamate be arranged and give sufficient for a comfortable operation fixation in any position of the pull-out path.
