Description

The present invention relates to a new rail system for food carriers in an oven.

For the purposes of this invention, the term “food support” refers to all inserts that are customary used in ovens, such as baking trays, racks, baking dishes, drip pans, etc. Furthermore, the term “food support” is understood to mean brackets for the aforementioned Oven trays, such as B. frame in which such inserts can be used or on which they can be placed. A food support in the sense of the invention therefore does not have to necessarily have a support surface for the actual food itself, but can also only for fastening or holding such a support surface, such as a baking sheet.

The terms "front" and "rear" as used herein refer to the oven, the food support or telescopic guides are used to designate an area that points towards the oven the oven opening (front) or towards the back of the oven. A common one The oven consists of a housing with outer walls of the oven and one arranged therein Muffle with muffle side walls, upper and lower muffle walls and a muffle rear wall, the interior of the muffle represents the actual cooking space of the oven.

Pull-out systems for food carriers in an oven are known in a variety of forms and are constantly developed and improved. In simple known ovens, the food support is in Grooves performed, which are formed at different heights or levels in the muffle side wall. The sliding behavior of the food support in such grooves depends on the surface quality of the sliding surfaces and the load on the food support and is comparative bad. In other systems, instead of the grooves on the muffle side walls, there are grids with horizontal ones Fixed bars on which the food carriers are guided. Because of the lesser The contact surface is slightly improved here compared to grooves. Both systems have the disadvantage that the food support is only pulled out of the oven to a certain width can be without it tipping down or having to be supported at the front. The top Groove boundaries or further horizontal provided at a short distance above the food support Lattice bars can prevent the food carrier from tipping up to a certain extent support and thus enable a somewhat longer extension path, a full pull-out of the food support up to the muffle without the food support being held by one person must be, however, is not possible with such arrangements.

In improved ovens there are telescopic guides on the muffle side wall or on a grid each with a stationary and one or more movable rails that run in the longitudinal direction are slidably mounted relative to the stationary rail and out of the furnace. On The food support can be placed on the movable rails so that the food support can be pulled out the telescopic guides can be pulled out of the oven. It is also a system known with telescopic guides, in which the lying on the movable telescopic guide rail After the movable rail has been completely pulled out, the food support is still to the stop slide a further distance on the rail until you reach the oven muffle can. This allows the use of telescopic guides with only two rails, which is what Costs is advantageous. Unfortunately, with this system it is imperative that the Telescopic rails in the inner hot area of the oven muffle are attached to the side wall, so that the food support can be placed on the movable rail of the telescopic guide. Due to this storage of the telescopic guides in the oven muffle, they are easy to get through Cooking food, splashing or evaporating fat or other liquids are dirty. This pollution are not only reflected on the outside of the telescopic rails, but also even in their inaccessible interior. Cleaning the telescopic guides inside, in particular, cleaning the bearings is practically impossible or only by inserting the whole Telescopic guides in a cleaning liquid or by pyrolytic cleaning at very high temperatures. In this case, however, lubrication or Lubricant also removed, so that the telescopic guides after repeated cleaning this way they lose their good sliding properties.

A general advantage of telescopic guides over the storage of the food support in grooves or on wires of a frame is their smoothness and stability and security against one Tilt the food support in the extended position.

The object of the present invention was to provide an improved rail system for food carriers To provide in an oven, the construction of the food support is inexpensive to manufacture and pulling the food carrier out of the oven or even stable up to the oven, allowed to slide easily and without tilting the food support and with the telescopic rails largely protected against contamination from food to be cooked and splashing or evaporating Fat or other liquids can be arranged.

The solution to the problem consists in a rail system for food carriers in an oven a food support, which has brackets on both sides, in the front section of the food support via an essentially U-shaped connecting section are connected to the food support and are essentially parallel to the respective side edges of the food support, and with telescopic rails, each one inside or outside the side wall of the oven muffle fixed stationary rail and one relative to the stationary Have rail slide out of the oven inner rail, being on the inner rail a forming essentially over the length of the inner rail and with this one unit Recording tube is provided, which is open in the direction of the oven opening and for recording of the bracket is designed by insertion, the bracket and the receiving tube a hook and a catch for releasably engaging the bracket and the receiving tube have against slipping out of the bracket from the receiving tube.

As already stated above, the food support according to the invention can be a baking sheet, a baking rack, be a baking pan, etc., on which the bracket via a U-shaped connecting portion fastened in the front section of the food support facing the oven opening are. Attach the actual support for the food and the two to the side of the food support Brackets then form a solid unit. Alternatively, the food support can also be a frame element be on which the two brackets are attached laterally. The frame element is designed that an insert, such as a baking sheet, a baking pan, a grid, etc., can be inserted into the frame and is held by it.

The back from the front section of the food support parallel to its side edges extending bracket are advantageously designed as rods, wires or dimensionally stable sheets. The Connecting sections between the brackets and the food support are substantially U-shaped formed, the U-legs each of a bracket and an associated Side edge of the food support are formed. The section connecting the U-legs is advantageous a section bent substantially perpendicular to the direction of extension of the holding bracket of the bracket, which is advantageous at the front side corner of the food support, in the the front edge and the side edge of the food support meet, ends. In a preferred embodiment of the food support according to the invention are the two holding brackets, the connecting sections to the food support and the front edge of the food support from one piece, preferably a stable wire. The food support, be it the frame element or the actual support surface itself, in this preferred embodiment, the retaining bracket is in one piece on this connecting section z. B. attached by welding and extends in one plane with the two brackets to the rear.

In a preferred embodiment, the telescopic rails of the invention Systems around conventional partial or full extension rails with a stationary rail and a movable inner rail for attaching the food support. Between the stationary Rail and the inner rail can be provided to one or more middle rails to increase the extension length of the entire telescopic rail and / or its load capacity or stability. Such telescopic rails are well known to those skilled in the art in a variety of forms. The Single rails of such telescopic guides are by cage-mounted balls, rollers, or rollers simple plain bearings slidably mounted against each other and have pull-out limiters that a Prevent the rails from completely sliding apart and separating.

According to the invention, a receiving tube is attached to the movable inner rail, into which the two Holding bracket of the food support when inserting the food support into the oven from the front be inserted. The receiving tube can be designed as part of the inner rail profile. To conventional rail elements commercially available for the system according to the invention However, to be able to use it is advantageous if the receiving tube is retrofitted to the inner rail is fixed or releasably attached. A firm connection can be achieved by welding, riveting or something similar. Examples of a detachable connection are screw connections, hook-in connectors Terminal connections. The receiving tube can be made of a metal tube or a bent one Made of sheet metal. In a particularly preferred embodiment of the invention, the receiving tube formed by a substantially U-shaped, elongated sheet profile in cross section, at which the ends of the U-legs are attached to the inner rail by welding. Especially It is advantageous if the U-shaped profile is rectangular or square in cross section.

In the system according to the invention are a hook and a catch on the bracket and the Receiving tube provided, through which the bracket and the receiving tube prevent it from being pulled out of the bracket from the receiving tube releasably engage with each other. at a preferred embodiment of the invention is the hook on the bracket and the latch in Formed a recess or opening on the receiving tube. The recess or Opening on the receiving tube is on the downward side of the receiving tube, and the hook on the bracket is also directed downwards and designed so that it when the food carrier is fully inserted and when the holding bracket is on due to gravity rest on the lower inner wall of the receiving tube, engages in this recess or opening. If the z. B. loaded with food to be cooked food holder horizontally from hooked bracket Pulled out the oven, the engagement of the hook and catch ensures that not the bracket pulled out of the receiving tube again, but the sliding out of the food support from the oven via the telescopic rails by taking the inner rail (and if necessary one or more middle rails). This is how the food carrier becomes for an assessment and processing of the food partially or completely pulled out of the oven muffle, and the food carrier sits stably and without being able to tip over on the telescopic rails. If the food support is to be completely removed from the oven, the engagement between The hook and catch on the holding bracket and receiving tube are released by slightly lifting the food support and pulled the retaining bracket out of the receiving tube. The system is simple and special in relation to the food support with the brackets very inexpensive to produce.

In a preferred embodiment of the invention the hook is a multi-curved one Section of the otherwise substantially straight bracket is formed. alternative the hook can also be welded to the bracket or in any other for the specialist simple way.

In a further alternative embodiment, the catch consists in an upward direction Bend on the bracket and the hook is as a protrusion at the bottom lying inner wall of the receiving tube. When inserting the food support the holding brackets are guided over the elevation in the receiving tube and lowered for engagement, as soon as the inflection on the bracket is above the elevation in the receiving tube.

In a particularly preferred embodiment of the rail system according to the invention the telescopic rails and the receiving tube outside the oven muffle, expediently arranged between the muffle side walls and the oven outer walls. This has several Benefits. The entire rail system is arranged outside the oven muffle and thus separated from the cooking space by the mold side walls. Contamination of the telescopic rails and also the receiving tube due to food, splashing or evaporating fat or others Liquids are essentially completely avoided. In addition, there is the rail system in an area of the oven that heats up considerably less during operation than that actual cooking space in the muffle. In addition, there can be between the rail system and the mold side walls thermal insulation may also be provided. This has the advantage that the bracket of the food support heat up much less than the food support itself and therefore when the food carrier is removed from the oven immediately or after a considerably shorter time Cooling time can be touched. In addition, there are lubricants and lubricants in the telescopic rails heated considerably less than if the telescopic rails inside the oven muffle would be ordered. This allows the use of lubricants or lubricants other than they would be required for higher temperatures, such as those prevailing in the oven cavity. This increases the choice of lubricants or lubricants that can be used, and these agents can be used before Background of cost, food safety, toxicity, etc. can be selected. At higher temperatures Resistant lubricants or lubricants that are also related to use are suitable and permissible with the preparation of food, only stand in fewer Choices are available and are often very expensive.

In an alternative embodiment of the invention, the rail system is in the muffle interior attached to the mold side walls. In this case it is useful if the telescopic rails and the receiving tube against contamination and / or excessive heating the rest of the cooking space are covered. Such a cover can e.g. B. formed as a sheet be from the muffle side wall over the telescopic rails and the receiving tube again extends to the muffle side wall. In the muffle there can also be one in front of the muffle side wall and the partition system arranged intermediate wall can be provided, which extends from the upper Muffle wall extends to the lower muffle wall in order to simultaneously have several superimposed To protect rail systems on the inner wall of the muffle.

It is particularly expedient according to the invention if the front opening of the receiving tube is around is a sufficient amount larger than the diameter of the bracket to insert the ends the bracket in the two openings of the two receiving tubes in an oven level if possible easy to design. In the case of a receiving tube, which is expedient for manufacturing reasons has the same cross section throughout, the bracket has due to its smaller Diameter in the receiving tube game and can wobble and rattle. To that To counteract, the receiving tube in a particularly preferred embodiment of the Invention in the rear area facing the back of the oven into the interior of the receiving tube extending tab or a projection on the game of the bracket inside of the recording tube is reduced. With a receiving tube designed as a bent sheet metal or profile this can be realized particularly advantageously and inexpensively by z. B. on the upper wall of the receiving tube makes a substantially U-shaped incision and the bends through the incision to the interior of the receiving tube. in this connection the free end of the tab should be aligned with the back of the oven, so that the bent Tab on the inside of the tube a slide or guide surface for the bracket when inserting the same offers. Instead of a tab, one can also protrude into the interior of the receiving tube Imprint or a z. B. welded elevation on the inner wall surface of the recording tube to reduce the game.

In an alternative embodiment, the game also has the bracket within the receiving tube reduced, the cross-section of the receiving tube tapers from the front area, in the opening for inserting the retaining bracket is towards the rear area in the direction the back of the oven.

In a further preferred embodiment of the invention there is a latch on the receiving tube provided, which prevents lifting of the food support when the bracket is in the receiving tube inserted and the hook and the catch on the bracket and receiving tube together are engaged. Such a lock prevents the food support or the Retaining bracket on it from the receiving tubes accidentally when the food carrier is inadvertently lifted be pulled out when the food support is actually only over the telescopic rails should be pulled in front of the oven muffle. Such a locking mechanism can be in one simply lock on the wall of the receiving tube latch, the advantageous locking positions in open and / or closed, d. H. locked position.

Figure 1 shows an oven in which the rail system according to the invention between the muffle side walls 11 and the oven outer walls 12 in three superimposed levels is. The rail system is thus completely separated from the actual cooking space in the muffle and protected against pollution and excessive heating. Furthermore, in FIG. 1 Two food carriers 1 are shown, of which the upper one is inserted into the oven and the lower one has moved out. The food support from Figure 1, that in the upper illustration of Figure 2 again reproduced, consist of a wire shelf as the actual food support, laterally parallel to the side edges 1a of the food support bracket 2, which is U-shaped trained connecting sections 3 in the front portion of the food support connected to this are. The food carriers are with hooks pointing downwards for engaging with a Provide rest of the rail system.

The lower illustration in FIG. 2 shows an alternative embodiment of the invention Food support 1, which differs from the embodiment shown in FIG. 2 above in that that the food support 1 has a holding frame 9 with side edges 1a, in one Baking pan 10 can be used appropriately.

FIG. 3 shows a detailed view of the rail system for food carriers according to the invention. shown is a telescopic rail 4 for mounting the system on the left side of an oven, if you look at the oven from the front. The telescopic rail 4 consists of two rail elements, a stationary rail 4a and a slidable relative to the stationary rail 4a Rail 4b. The stationary rail 4a is on the muffle side wall or between the muffle side wall and oven outer wall, as shown in Figure 1, by screwing, hooking or attached any other known way. On the movable rail 4b is in the direction attached to the interior of the oven a receiving tube 5. The receiving tube exists with this Embodiment made of a sheet metal profile with a square, substantially U-shaped cross section. The free ends of the U-legs of the profile are slidable on the outside of the C-shaped Rail 4b attached. The attachment can be by welding, screwing or any other appropriate method. Alternatively, a square or rectangular cross section can also be used and four-sided profile are used, with one side on the back of the sliding Rail 4b abuts and serves as a mounting surface.

The receiving tube 5 has a latch formed in the lower wall surface as an opening for the Engage with the hook 6 of the bracket 2 on the food support. In Figure 3 is the headband 2 of the food support is shown broken off. The bracket 2 is a straight wire or Rod formed, the hook 6 a deflection of the wire or rod in a downward direction pointing direction.

The receiving tube 5 has in the vicinity of the rear end facing the rear of the oven a tab 8 attached in the upper wall. The tab 8 is by cutting the Wall material and turning in the direction of the interior of the receiving tube 5. The free end of the tab 8 points towards the back of the oven, so that the tab 8 on the one hand the play of the bracket 2 in the receiving tube 5 in this area is reduced or substantially completely prevented and on the other hand also forms a guide surface on which the bracket can slide along when inserted into the receiving tube 5. The tab can be used as Element with a certain spring force advantageously so far into the interior of the receiving tube protrude so that the inserted bracket under spring tension against the inner wall of the receiving tube presses and thus a game of the bracket in this section of the Recording tube completely prevented.

When placing the food support in the oven, d. H. the insertion of the bracket 2 in the Receiving tube 5, the hook 6 on the bracket 2 occurs when lowering or setting down the food support into the opening or rest 7. If the food support is then in the horizontal direction from the When the oven is pulled out, the food support slides over the telescopic rail 4. by moving the movable rail 4b due to the locking of the holding bracket 2 and the receiving tube 5 is carried by hook 6 and rest 7.

FIG. 4 shows the receiving tube 5 from FIG. 3 with the holding bracket 2 inserted in cross section. The Tab 8 on the receiving tube 5 is bent down so far that the bracket 2 is little Has play in the receiving tube 5.

On the receiving tube according to FIGS. 3 and 4, the catch 7 and the hook 6 can still be used a locking device (not shown) may be provided which holds the bracket 2 in the area of the hook 6 or in front of or behind it in a locked position down, so that the locking of the bracket 2 and receiving tube 5 in the horizontal direction is not by lifting of the bracket 2 can be solved.
