Door handle for cookers

The present innovation relates to a door handle, in particular to one in a door front for the rest position Retractable door handle for cookers, preferably for built-in ovens, the door handle extending essentially over the Backoi'en door width extends and in the door construction over Door handle arms arranged on both sides is supported.

From design, manufacturing and For functional reasons, door handles are \ ielche across the entire width or / ifKer the entire width of the roof oven door, widespread, over both

These door handles are in the Door construction either firmly anchored or stored in such a way that it optionally protrudes from the door front Working position or can be adjusted into a rest position that can be lowered into a recess in the door front. Not least for optical reasons, the elongated door handles are designed to be as flat and narrow as possible. This can lead to the fact that with vigorous and jerky operation bending can occur, which also affect the Door handle arms and the overall door construction have a detrimental effect. In addition, such door handle constructions to consider that often in the side areas of the door handle ventilation openings in the door or the front of the device are arranged, via which the cooling air for the control electronics and / or the vase outlet is led.

The task of the innovation is now to provide a door handle, which is advantageous in terms of functionality and operation compared to the known State of the art stands out and which at the same time also has manufacturing and, in particular, design engineering Concerns taken into account.

A door handle that meets these requirements in particular corresponds to pronounced dimensions, according to the innovation characterized in that the door handle is reinforced in the central area in cross section.

This measure, taken according to the innovation, has various advantages. Due to the cross-sectional reinforcement in the middle

TZP 8 ^ / 705

In the area of the door handle, the moment of resistance directed against a bending moment is applied at the usual actuation point of the door handle increased significantly, so that the door handle through the reinforcement only in this area becomes much more stable. In addition, the reinforced design of the door handle in the central area leads to that operators are informed of this area purely optically and are thereby caused to touch the door handle preferentially in this area as well. That’s a symmetrical actuation of the entire door construction given, so that twisting by the actuation does not occur are feared. Since the operator is encouraged by the shape of the door handle, the door handle in the middle To actuate the area, the risk of them entering the area / possibly laterally from outlet openings is also reduced warmed or heated cooling air or fume extractor escaping from the door and / or device front. Through the narrower one Training of the door handle in the outside area is also the attack surface of the door handle for warming by the Cooling air or vapor extraction is greatly reduced. The overall door handle is heated to an uncomfortable level thereby prevented. By designing the door handle as a plastic part, heat will spread into the actual Grip area additionally counteracted.

According to a preferred embodiment, one is in the door front retractable door handle according to the invention characterized in that that the door handle in the central area in cross section in the direction of the door front is reinforced is. The door handle, which is sunk into a recess in the front of the door in the rest position, thus faces the viewer directed uniform and parallel to the bulge

directional appearance, as the reinforcement of the cross-section is ^{only designed} in the direction of the door front. In addition, this measure offers the possibility of providing outlet openings for cooling air and vapor extraction in the side areas of the hollow, for which a flow cross-section that is still tolerable when the door handle is pushed in is created. In baking operation, however, the door handle should be in the working position. If the door handle is folded forward by a swivel mechanism and at an angle downwards, the flattened areas in the outer areas of the door handle of the cooling air and the fume extraction through the door handle hardly offer any, but at least a greatly reduced attack surface.

The door handle according to the invention is particularly favorable and advantageous in that the reinforced cross section of the door handle has a shape similar to an equilateral triangle with rounded corners. One through

f these corners running edge, especially that of the door front

in the rest position of the door handle facing edge is in

ι; the outer areas then flattened further.

An embodiment designed according to the features of the present innovation is based on the drawing explained in more detail below. Show it:

Fig. 1 is a partial view of a door structure in the handle area from the side and

Fig. 2 is a longitudinal view of one in the recess the door front of the indented door handle.

TZP 84/705

In an oven door 1, the door handle 2 is mounted pivotably about a pivot axis k by means of door handle arms 3 arranged on the side, so that the door handle 2 can assume the working position shown in FIG. 1 or, in the position shown in FIG. In the middle area, the door handle 2 - as can be seen in particular from FIG. 2 - is designed to be reinforced in relation to the itand areas. The respective cross sections of the door handle 2 can again be seen in FIG. 1, the cross section of the central area being shown hatched and surrounded by a continuous contour line 6, while the flattened contour of the door handle cross section in the outer door handle areas is shown in dashed lines.

It can be seen in particular from FIG. 2 that in the outer areas of the door handle recess 5 ventilation slots 8, 9 are incorporated, through which cooling air flows from the control electronics and / or fume extractor, the flattening of the Outside areas of the door handle 2 prevents these ventilation slots 8, 9 from being pushed into the rest position Door handle 2 are unnecessarily covered by this. Rather, there can be enough air in this area flow through to a large extent. It can thus be seen that in addition to the function of the reinforced central area of the Door handle as a reinforcement measure and as a reference measure on the preferred area of attack, according to the innovation Training the door handle also has a positive effect on the exhaust air outlet.
