Abstract

The oven of the invention comprises a rack ledge (1) which is provided on each of the opposing side walls of the oven cavity, which extends from the front end (3) towards the rear end (4), which comprises multiple horizontal wires (5) thereon, which has, between two neighboring horizontal wires (5), a gap (10) into which the side bar (9) of the oven rack is seated; at least one oven rack (2) which is slidable towards the rear end (4) and back end (3) on said rack ledge (1) and on which the food stuff to be cooked are placed. The oven is also provided with at least one vertical support rod (7) which interconnects at least two horizontal wires (5).

Description

Technical Field

Present invention relates to rack ledges in the ovens used for cooking food.

Prior Art

As is known, among the cooking devices, ovens are commonly used ones which perform cooking in a closed cavity. Slide racks in the form of wire grid or tray are usually employed for placing the food to be cooked in this cavity. On both of the opposing side walls of the oven cavity are provided ledges between which the side bars of the racks are suitably seated in order to slide the racks forwardly / backwardly within the cavity.
Published patent application No WO2004020908 can set an example for such ledges. This patent application discloses rack ledges which are formed on side walls of the oven and are integral with said wall. This application also presents rack ledges which are designed to be mounted to side walls and are which are composed of horizontal wires, between the gaps of which the racks are seated. However, said horizontal wires advance through the oven cavity without being supported, which result in bending of these horizontal wires due to the loads of the rack. Owing to this bending, there is a risk that the racks (particularly the extended ones) may be angled and the contents of the rack may drop.

Brief Description of the Invention

The oven of the present invention comprises a rack ledge, which is provided on each of the opposing side walls of the oven cavity, extending from the front end towards the rear end, comprising multiple horizontal wires thereon, having, between two neighboring horizontal wires, a gap into which the side bar of the oven rack is seated; at least one oven rack which is slidable back and forth on said rack ledge and on which the food stuff to be cooked are placed.
When the rack is extended, the rack (assuming an angled position) applies pressure on the two above and below horizontal wires due to the weight of the rack and of the load (food to be cooked) on the rack. In this case, at least one vertical rod, which interconnects at least two horizontal wires, is employed, preferably near the front end of the rack ledge, in order to prevent the rack from bending the wires further. Vertical rods support the horizontal wires, preventing their further bending. In addition, at least one horizontal wire has a downward flexion near the front end of the rack ledge. When the rack is extended, the back of the rack leans onto this flexion. Thus, over extension of the rack and inadvertent dislocation thereof is prevented, ensuring the safety of the user.

Objective of the Invention

The aim of the invention is to provide durable rack ledges for ovens which are used for cooking food stuff.
Another aim of the invention is to prevent said rack ledges from being further bent due to the loads on the rack.
Another aim of the invention is to ensure safety of the user by preventing over extension of the rack and inadvertent dislocation thereof when the rack on the ledge is extended.
Another aim of the invention is to provide rack ledges having said properties, which are simple and cheap to manufacture.

Description of the Drawings

An example of the rack ledge of the invention and rack is illustrated in the annexed figures wherein:

Figure 1 is the perspective view of the rack ledge and rack.
Figure 2 is the side view of the rack ledge.
Figure 3 is the side sectional view of the rack ledge and the rack.
Figure 4 is the view of the detail "D" in Figure 3.

The parts in the figures are individually enumerated and corresponding terms of these reference numbers are as follows:

Rack ledge: (1)
Rack: (2)
Front end: (3)
Rear end: (4)
Horizontal wire: (5)
Flexion: (6)
Vertical support rod: (7)
Back of the rack: (8)
Side bars of the rack: (9)
Space: (10)

Disclosure of the Invention

Figure 1-4 illustrates a rack ledge (1) used in the cavity of the oven (the oven and the cavity are not shown) and the rack (2) which is mounted to this ledge (1). The rack ledge (1) is a component which is provided on each of the opposing side walls of the oven cavity.
Multiple horizontal wires (5) are located on the rack ledge (1); these wires (5) are positioned such that they extend from the front end (3) towards the rear end (4). The gap (10) between the two neighboring wires (5) receives the side bar (9) of the rack (2).
The figures show the rack (2), by way of example, as a wire grid; however racks in the form of tray are also used. The rack is slidable back and forth (between the front and rear ends (3, 4)) within the gap (10) between the two horizontal wires (5). As the rack (2) is extended towards the front end (3), the back of the rack (8) leans onto the above horizontal wire (5) and becomes angled to some extent.
The manufacturers tolerate this angled position by to a certain degree. At this position, the rack (2) applies pressure on the two above and below horizontal wires (5) due to the weight of the rack (2) and of the load (food to be cooked) thereon. In this case, at least one vertical rod (7), which interconnects at least two horizontal wires (5), is employed, preferably near the front end (3) of the rack ledge (2), in order to prevent the rack (2) from bending the wires (5) further and to prevent the rack (2) from becoming angled more. Vertical rods (7) support the horizontal wires (5), preventing bending of the wires (5).
In addition, at least one horizontal wire (5) has a downward flexion (6) near the front end (3) of the rack ledge (1). When the rack (2) is extended towards the front end (3), the back of the rack (8) leans onto this flexion (6) at this extended position. (Front end of the rack (2) is lifted up for removing the rack (2) from the ledge (1)). When the rack (2) is at this position, sliding of the rack (2) towards the front is prevented since the front end of the rack (2) is angled downwards at a certain degree. Furthermore, the vertical support rods (7) are preferably located near the flexion (6) at this position of the rack (2), wherein the rack (2) applies the most pressure on the two horizontal wires (5). The figures, for instance, show the support rods (7) along the both sides of the flexions (6). Easy reproducibility of the rack ledge (2) structure formed by the present invention is another advantage offered by the embodiment of the invention.

Claims
