Description

Gargutträgerauszugsystem

The invention relates to a Gargutträgerauszugsystem for an oven with two mounted on the side walls of the baking muffle rail carriers, wherein in at least one plane of the oven, preferably in several levels, rail members for a trained with an outer rail, an inner rail and optionally one or more middle rails telescopic rail are firmly or detachably mounted

There are known Gargutträgerauszugsysteme for ovens, in which on the side walls of the oven muffle rail support elements are provided which have in several of the levels of the oven telescopic rails with an inner rail, an outer rail and optionally one or more middle rails. Furthermore, ovens are known in which the telescopic rails are removed from the oven and can be used again in another level of the oven or assemble.

From DE-A-3 628 763, for example, an oven is known which has on the side walls of the oven muffle a holding grid with ball-bearing telescopic rails in each level of the oven. The telescopic rails are partial extension rails, each with a stationary, mounted on the holding rail rail and a movable rail, which are slidably mounted on cage-mounted balls against each other. Food carriers are placed on the movable rail and moved together with this out of the oven or in this. Since the telescopic rails are partial extracts, the movable rails can not be pulled up to their full length from the oven muffle in front of the oven. In order to still be able to pull the food support completely up to the oven, the movable rails and the food support are designed so that the food support is slidably pulled out at a complete excursion of the movable rail for a further distance on the movable rail. This excerpt about the additional distance is limited by stops on the rail elements and counter stops on the food support.

Ball-bearing telescopic rails have the advantage that they are particularly smooth and quiet and oppose the extract a very low initial friction resistance. However, ball-bearing telescopic rails are material and costly and can be difficult to clean. The ball bearings require the use of grease for easy and quiet running, which requires additional material and operations in manufacture. In addition, the grease over time consumes and collects dirt from the oven. Greasing the ball bearings of telescopic rails in ovens is usually practical not performed and not offered by the manufacturer. The running properties of the ball-bearing telescopic rails therefore worsen after prolonged operation. Another problem arises at high temperatures at about 500 ° C, as z. B. be used in self-cleaning pyrolysis. There are no longer greases that can withstand the high temperatures and at the same time are permitted in the food industry. Suitable greases are relatively expensive.

Another disadvantage of ball-bearing telescopic rails is that the rail elements can not be easily separated from each other, as they are connected to each other via the cage-mounted balls substantially inseparable. Concealed areas of the telescopic rails, in particular those areas between the rail elements, are therefore difficult or impossible to access for cleaning.

Another disadvantage of known Gargutträgerauszugsysteme is that in each level of the oven a pair of telescopic rails is provided so that in each level a food support is used. The high number of telescopic rails thus increases the cost of the entire system.

Compared with known systems, the present invention has the object to provide a Gargutträgerauszugsystem that is cheaper, more flexible and easier to clean.

This object is achieved by a Gargutträgerauszugsystem of the aforementioned type, wherein the rail members mounted on the outer rail elements have a substantially U-shaped profile and are designed for the insertion of a food support, if no further rail elements are mounted on these Oßenschienenelementen, and the Außenschienen- elements for the detachable mounting of inner rail elements and possibly middle rail elements are designed, wherein the inner rail elements have on the upper surface bearing surfaces for the placement of a food support.

The term "outer rail" herein refers to the rail element of a telescopic rail which faces the oven wall and is fastened to the rail support, irrespective of whether this rail element engages around another rail element or is encompassed by another rail element. The outer rail in the sense of this application is thus the stationary rail element. The term "inner rail" herein refers to the rail element of a telescopic rail, which faces away from the oven wall and faces the oven interior. In the inner rail in the sense of this application is thus the movable rail element. As a "middle rail" another movable rail element is referred to, which is mounted between the outer rail and inner rail and slidably mounted relative to both the outer rail and the inner rail. The term Gargutträger in the context of this application includes all trays commonly used in ovens, such as baking trays, baking grates, drip pans, etc.

A very particular advantage of the product support pull-out system according to the invention is that the outer rails fixedly or detachably mounted on the rail support fulfill a dual function not previously described. First, together with an inner rail element and, if appropriate, a middle rail element, they can form a telescopic rail for the sliding or displaceable mounting of a food support. The telescopic rails may be formed as a partial extension, consisting of an inner rail and an outer rail, or as a full extension, consisting of an inner rail, a middle rail and an outer rail. Second, the outer rail is also designed so that it alone, d. H. if no inner and middle rail elements are mounted on the outer rail, used as a receptacle for a food support. In this latter case, the food support is inserted into the stationary, substantially U-shaped outer rail from the front, as is known from simple ovens, which have in the muffle side wall guide grooves for receiving food supports.

This double function of the outer rail allows a flexible design and equipment of the oven with Gargutträgereinschüben. The two variants can be converted into one another by simple assembly or disassembly of inner and optionally middle rail elements on the stationary outer rail. The system is also very flexible in that either only an inner rail element or an inner rail element and a middle rail element can be mounted on the outer rail. Thus, telescopic rails can be realized either as a partial or full extension.

For the entire oven, initially only two complete telescopic rails, which are designed either as a partial or full extension, required. These telescopic rails are mounted in a preferred plane of the oven. In all other levels of the oven, the outer rail elements attached to the rail carriers can serve as inserts for the insertion and storage of food carriers. If the preferred level in the oven changes, the movable elements of the telescopic rail can be removed from the outer rail element fastened to the rail support and mounted in the new plane on the rail elements fastened to the rail support. Thus, a Gargutträgerauszugsystem is provided, which is very variable and requires only a few components. The fact that all parts can be separated from each other, the food product tray system according to the invention is also extremely easy to clean.

The product support pull-out system according to the invention can be realized both with roller-mounted or roller-mounted telescopic rails and with slide rails. Ball-bearing telescopic rails, however, are unsuitable because mounting and dismounting of ball-bearing telescopic rails, ie Separation of inner, outer and possibly middle rail elements are considerably more expensive than sliding rails or roller or roller-mounted telescopic rails. Particularly preferably, the telescopic rails of the present invention are designed as slide rails. They manage without additional ball cages with the balls guided in them and are easy to assemble and clean. In addition, they require little or no grease. Roller or roller-mounted telescopic rails are also suitable. Since the rollers or rollers are mounted on rail elements, they are also easy to assemble and disassemble.

The Gargutträgerauszugsystem invention has a high variability to the effect that the individual levels of the oven can be configured individually by the user. Each level can with telescopic rail as Vollauszugschiene, with telescopic rail as Teilauszugschiene or as a simple slot without telescopic rail, z. B. as an auxiliary level for holding a drip pan or for storage of unused food supports, be configured. The system has few components and therefore offers easy handling, is very robust, easy to clean and offers high safety. When using sliding rails, it can not come to an autonomous moving apart of the rail elements, even if the oven is placed slightly inclined forward since the initial resistance of slides is higher than, for example, with ball-bearing telescopic rails.

Furthermore, the system according to the invention with slide rails or roller-mounted or roller-mounted telescopic rails also has advantages in terms of its production. It is easy to manufacture, allows greater tolerances than ball-bearing telescopic slides and quick, easy installation.

The rail supports of the system according to the invention are designed so that they each hold a pair of outer rail elements in a plane of the oven on opposite side walls of the oven muffle in a horizontal position. The outer rails can either solid, d. H. insoluble, such. B. welded or soldered to be connected to the rail carriers. Or, according to a preferred embodiment of the invention, they can be removed detachably, i. H. detachable, be mounted on the rail supports. The removable mounting can be realized by hooking, screwing or any other suitable fastening means.

The rail supports of the system according to the invention can - for one side wall of the oven - be formed in one piece or in several parts. The embodiment is advantageous as a one-piece grid or as a grid-like construction of solid wire or steel tube with fastening means for the outer rails. Or the outer rails can also be connected directly insoluble with the grid. Alternatively, the rail support may advantageously be designed in several parts, z. B. as two vertical rails or profiles with fasteners for the horizontal mounting of the outer rails or with already horizontally fixed and permanently attached outer rail elements. Such rail supports are also referred to as "verticals".

In a further alternative embodiment, the outer rails may advantageously also be directly fixed, but expediently rather detachably connected to the muffle side walls, without an additional grid or another structure being present. In this case, the muffle side wall acts as a rail carrier in the sense of this invention.

It is particularly advantageous if the rail supports are detachably connected to the side walls of the baking muffle. This way, they can be taken out of the oven and especially easily cleaned outside the oven. In addition, so the outer rails, if they are designed releasable from the rail carrier, removed and cleaned outside of the oven from the rail support or even remounted in another plane.

In a preferred embodiment of the removable rail support, the rail supports on the sides, which each face the muffle side wall, perpendicular or substantially diagonally downwardly projecting pins or hooks, which engage in the side walls of the oven muffle. The rail supports can be easily mounted by inserting into corresponding openings in the side wall of the oven muffle. During installation, no screws or clamps need to be loosened, and the rail supports are nevertheless reliably anchored in the oven since their main load is from above, thereby preventing the rail supports from being removed. Alternatively, however, any other type of releasable attachment is suitable, such. B. an attachment by means of screws or clamps,

The Garguträgerauszugsystem invention is designed so that when mounted in a plane telescopic rails with outer, inner and optionally middle rails, the food support is placed on top of the inner rail. Suitable fasteners, which will be described below, fix the food support against a move on the inner rail, so that the food support is movable together with the inner rail element and can be inserted into the oven or pulled out of this. The width and shape of the edge regions of the food support are chosen so that they come to rest on the corresponding bearing surfaces of the inner rails and provide sufficient contact surface for secure support. At the same time, the width of the food support and the shape of the outer rails are selected so that the edge of the food support in alternative use of the outer rails, namely as a pure insert without mounted inner and possibly middle rail elements, sufficiently deep into the U-shaped profile of the outer rail protrudes, so that a secure holder is guaranteed here. It is expedient if the telescopic rails have on the side of the oven opening Auszugsanschläge which prevent the movable rail elements (inner rails and possibly middle rails) can be pulled so far out of the stationary rail elements when pulling out of resting on the inner rail elements Gargutträgers that they from each other be disconnected and fall out. According to a preferred embodiment, the extension stops are formed as beads in the inner rail elements and possibly also the middle rail elements. These can be easily produced by punching and pressing in the rail elements. In an alternative embodiment, the extension stops are designed as tabs on the upper side, the lower side or the vertical wall of a rail element. The layers are inflected substantially perpendicular to the longitudinal axis of the rail elements. The tabs are advantageously formed by cutting a tab shape into the rail metal and bending the tab towards the rail interior or rail exterior.

According to a further preferred embodiment of the invention, the extension stops of the telescopic rails are designed as rotatably mounted, unlockable hooks or pawls on the inner and / or middle rails. If the unlocking is actuated, then the movable rail elements can be deducted from the rail elements fastened to the rail supports and removed forwards from the oven. They can then be pushed onto the outer rail elements mounted there in another plane. Conveniently, the hook or pawl is rotatably mounted on the rail member such that the hook or pawl falls into the locked position by gravity and the unlocking must occur by flipping the hook or pawl. Thus, the locked state sets itself, and the risk of accidental Entriegeins is reduced.

In a further preferred embodiment, in the front, the furnace opening facing region of the upper leg of the U-shaped profile of the outer rails to the rail interior protruding beads or tabs are provided. These also prevent tilting of the food support when the outer rails are used as inserts without inner and with eleschienenelemente in the oven.

According to a further preferred embodiment of the invention Eiπschubbegrenzer for the food support are provided on the rail elements. These prevent the food support, either by telescopic rail or inserted into the outer rail, is inserted too far into the oven and thereby abut the food support or rail elements to the inner oven back wall. As a slide-in limiter expediently suitable in the rear region of the furnace on the outer rail mounted bolt to which the food support or the inner and / or middle rail elements strike in the inserted state. Instead of a bolt, the insertion limiter can also be designed as a bent tab. In an alternative embodiment, the telescopic rails have no insertion limiter on the side facing away from the furnace opening side. On this page, the stop of the food support or the rail elements is then formed by the baking muffle back itself. To cushion or damp the rear stop silicone rubber elements may be provided at corresponding locations in this case.

Rail support and rail elements of the telescopic rails are conveniently made of stainless steel, as this withstands high temperatures, it can be easily cleaned and maintains a high quality appearance even after prolonged use.

According to a further preferred embodiment, the inner rail elements of the telescopic rails on which the food support can be placed on mandrels, which engage in correspondingly placed recesses in the food support. Thus, the food support is fixed in the direction of insertion on the inner rail and guided stable during insertion and removal and can not fall off the rails. Sufficient is in each case such a mandrel on each Inneπschiene, but it can also be provided two or more mandrels per rail.

The Gargutträgerauszugsystem invention is particularly suitable for installation in ovens, but there are also other applications conceivable that should be covered by the scope of the patent claims marriage, such. B. appropriate pullout systems in refrigerators or freezers, dishwashers and in electronic cabinets.

Further advantages, features and applications of the present invention will become apparent from the following description of preferred embodiments and the accompanying figures.

Figure 1 shows a broken view of a first embodiment of the invention from the front.

Figure 2 shows a side view of the first embodiment of the invention. Figure 3 shows a broken view of a second embodiment of the invention from the front.

FIG. 4 shows a broken-off detailed view of the rail lock according to the second embodiment of the invention.

Figure 5 shows a roller or roller-mounted telescopic rail of another embodiment of the invention from the front and the inner rail in a broken view from the side.

FIG. 6 shows a combined telescopic rail with roll-bearing or roller-mounted inner rail and middle rail designed as a slide rail element according to a further embodiment of the invention from the front. FIG. 1 shows a first embodiment of the product support pull-out system according to the invention with the rail carrier 1, which has fastening elements 3 in the heights of the respective planes of the oven, on which the outer rails 2 of the telescopic rails 11 designed as slide rails are fastened. The rail carrier 1 has downwardly angled hooks 4, which are inserted or attached to fasten the rail carrier in the oven in openings on the muffle side wall. This connection is stable and safe, since the main load of the rail carrier 1 is made from above, but at the same time allows removal of the rail carrier from the oven without loosening screws or clamps.

On the fasteners 3 outer rails 2 are fixed with a substantially U-shaped profile of the telescopic rails 11. These are not removable in the embodiment shown, but firmly connected to the rail carrier 1. On the outer rails 2 inner rails 6 or middle rails 5 can be postponed. In the uppermost level of the oven shown in Figure 1, an embodiment is shown in which on the outer rails 2 both a middle rail 5 and above an inner rail 6 is pushed. The three rails form a telescopic rail 11 for the full extension, which in the embodiment shown as a slide, d. H. without ball bearing, is executed. In the second level in Figure 1, a trained as a partial extension telescopic rail 11 is shown, which consists only of the permanently connected to the rail support 1 outer rail 2 and an inner rail 6. In this version as a partial extension of the food support can not be fully pulled out to the oven muffle.

The upper side of the inner rail 6 has a support surface for a food support 7. From the bearing surface of the inner rail 6 is a mandrel or pin 8 upwards, which engages through the application of the food support 7 through a corresponding opening in the food support and fixes the food support against displacement on the inner rail 6. In the illustrated in Figure 1 above, designed as a full extension telescopic rail 11 is provided on the inner rail 6 a down to the middle rail 5 projecting tab 9. The tab 9 serves as a driver for the middle rail 5 when retracting the telescopic rail 11. Without the trained as a driver tab 9 is when retracting the telescopic rail 11 the risk that the middle rail 5 stops and the inner rail 6 is guided past the center rail 5. A corresponding tab 9 is also provided on the inner rails 6 and 6 "of the telescopic rails shown in Figure 3 above or in Figure 5 as a full extension.

A bolt 10 passing through openings in the outer rail 2 in the rear region of the oven serves as a slide-in limiter. The inner rail 6 and the possibly existing center rail 5 can only be pushed into the oven until it is connected to the bolt 10. In this way it is prevented that the food support or the rail elements abut when pushed against the furnace rear wall and / or are pushed too far into the oven. The bolt 10 may be detachably screwed or plugged in so that it is removable from the outer rail. After removal of the bolt 10, the inner rail and, if present, the middle rail can be pulled off to the rear with the rail support removed. In this way, the rail elements can be separated for cleaning or for moving to another level of the oven.

The trained in Figure 1 above as a full extension telescopic rail 11 has on the inner rail 6 at the rear end, d. H. the end, which faces the muffle back, a bent in the direction of the middle rail 5 tab 18. The middle rail 5 has at the front end region a bent in the direction of the inner rail 6 tab 17. The tabs 18 and 17 represent stop and counter stop and serve as Auszugsbegrenzer, the deduction of the inner rail 6 of the middle rail 5 when pulling the food support from the oven to prevent. Similarly, the middle rail at the rear end portion on a bent in the direction of the outer rail 2 tab 19, and the outer rail has a stop 20 at the front end portion. Lug 19 and stop 20 thus form an excerpt limit for the middle rail 5 and the outer rail. 2

The partial extension rail 11 shown in Figure 1 in the middle level has on the inner rail 6 a the tabs 18 and 19 corresponding bent tab 19 ', which comes to rest on the limit stop on the stop 20 of the outer rail 2, when the maximum allowable Auszugsweg reached is.

The lowest level shown in Figure 1 shows the outer rail 2 without the inner rail 6 and middle rail 5, so that no telescopic rail 11 is formed in this plane. A food support 7 can now be inserted directly, as shown in Figure 1, in the U-shaped profile of the outer rail 2 or optionally also placed on the outer rail 2. If the lowest plane shown is also to be used with a telescopic rail, then an inner rail 6 and, if appropriate, a middle rail 5 are pushed onto the outer rail 2.

FIG. 3 shows a second embodiment of the invention with an extension limit for the middle rail 5 '(upper illustration in FIG. 3) or the inner rail 6' (lower illustration in FIG. 3), which is designed as a latch 12. The telescopic rail 11 shown in Figure 3 above is designed as a full extension and the telescopic rail 11 shown below as a partial extract. Like parts, as already described with reference to Figure 1, I have the same reference numerals. FIG. 4 shows a detailed view of the center rail 5 'from FIG. 3 in the section in which the bolt 12 is provided for the extension limit. As shown in Figure 4 from the side and from the top, in this alternative embodiment of the invention, the Auszugsbegrenzer on the center rail 5 'of the telescopic rail 11 shown in Figure 3 above as a rotatably mounted latch 12 is formed with a stop surface 14. The latch is mounted near the end of the rail which faces the back of the oven. The latch 12 is rotatably mounted about an axis 13. In Figure 4, the latch 12 is shown simultaneously in two different positions, namely an unlocked position ("E", thin lines, horizontal latch position) and a locked position ("V", thick lines, tilted latch position.) In the lower part of Figure 4 the latch 12 is also shown in plan view, in the locked position (V) the abutment surface 14 of the latch 12 is within the U-shaped profile of the outer rail 2 in a higher (off-center) position than in the unlocked position (E) which is the latch 12 in a substantially horizontal and the stopper 14 in a central position, based on the U-shaped profile of the outer rail 2. If the latch 12 in the locked position (V), the stop 14 strikes the extract The middle rail 5 'is stopped at the stop 15 of the outer rail 2 shown in Figure 3, and the rail extension is stopped m extract the inner rail 6 passed under the stop 15 of the outer rail 2 and the rail elements are separated from each other. In the embodiment of the telescopic rail 11 shown in Figure 3 above, the center rail 5 'is deducted together with the inner rail 6 of the outer rail 2, when the bolt 12 is unlocked at the middle rail 5'. In the embodiment of the partial extension telescopic rail 11 shown in Figure 3 below, the bolt 12 is provided in a corresponding manner on the inner rail 6 '. An advantage of the pull-out limiter designed as a detachable latch 12 is that the rail support 1 does not have to be removed from the oven side wall and removed from the oven for separating the inner rail elements 6 and the middle rail elements 5 'from the outer rails 2. After loosening the bolt 12, the associated rail element can be easily pulled forward from the oven out. The provided in Figure 1 as a slot limiter releasable bolt 10 may be provided in the embodiment of Figure 3 with releasable latch 1 as a fixed Einschubbegrenzerelement, z. B. as a bent solid tab oa

Preferably, the latch 12 and its rotatable attachment to the axis of rotation 13 are designed so that the latch 12 moves by gravity even in the locked position. In the embodiment shown in FIG. 4, this means that the rotatable mounting is smooth and the left lever arm of the bolt 12 seen in FIG. 4 from the pivot point 13 is heavier than the right lever arm.

FIG. 5 shows a roller-mounted or roller-mounted telescopic rail 11 'which is suitable for the food product tray system according to the invention and which is designed as a Voilauszug. In the same way as the slide rails according to FIGS. 1 to 4, the roller-mounted or roller-mounted telescopic slide ne 11 'according to Figure 5 also form a partial extract without middle rail. Elements of the telescopic rail 11 'of Figure 5, which correspond to the same elements of the telescopic rails of Figures 1 to 4, are designated by like reference numerals. 5, the telescopic rail 11 'has an outer slide 2 with a stop 20 as an extension limit for the middle rail 5 ". Furthermore, the middle rail 5 "has a lug 17 bent in the direction of the inner rail 6" and the inner rail 6 "has a lug 18 bent in the direction of the middle rail 5" for the pullout limitation in the manner described above.

On the middle rail 5 "rollers or rollers 30 are provided with axes of rotation 31 at the opposite sides in profile rollers, which roll when moving the middle rail 5" on the corresponding outer surfaces of the outer rail 2. A plurality of rollers or rollers 30 are distributed over the length of the middle rail element 5 "in the same way. Rollers or rollers 32 rotatably mounted about axes 33 are provided in the same way on the inner rail 6". The bottom view in Figure 5 shows the inner rail 6 "broken off from the side which the middle rail 5" faces. A plurality of rollers are equally spaced along the length of the inner rail 6 "distributed to ensure a uniform rolling relative to the center rail 5". 5, the axes of rotation 33 of the rollers 32 are supported, on the one hand, in corresponding bores on the side of the rail facing away from the middle rail 5. On the opposite side of the rail, ie the bent-over end portions of the rail C-shaped profile, recesses for the insertion and insertion of the axes of rotation 33 of the rollers 32 are provided.

When separating the inner rail 6 "and the middle rail 5" of the outer rail 2, the rollers or rollers remain fixed to the rail elements and do not fall out of the rail elements, which would be the case with conventional cage-mounted balls. Roller or roller-mounted telescopic rails offer a good running behavior and ease of movement of the telescopic rails, but do not require compared to ball-bearing telescopic rails the tight manufacturing tolerances.

6 shows a combined telescopic rail with a roller or roller bearing inner rail 6 "and a middle rail 5 designed as a sliding rail element according to a further embodiment of the invention The inner rail 6" is designed essentially like the inner rail shown in FIG. 1, and the middle rail 5 is essentially like the middle rail shown in Figure 5, which is why these rail elements have the same reference numerals as in Figures 1 and 5 respectively. The telescopic rail in Figure 6 is for illustrative purposes without excerpt limiter, insertion limiters, etc. shown. It goes without saying, however, that the rail according to FIG. 6 may also be suitably equipped with the same additional elements as the rails of FIGS. 1 to 5.
