The invention proceeds from a household appliance as claimed in the preamble of claim 1.
A telescoping pull-out device of a pull-out system for an oven with a first telescoping rail supported to allow it to move between a retracted and an extended position is known from EP 1 014 004 B1.
The underlying object of the invention is especially to provide a generic telescoping pull-out device in which an uncontrolled and/or undesired automatic extension of the first telescoping rail can be avoided.
The object is achieved in accordance with the invention by the features of claim 1, while advantageous embodiments and developments of the invention can be taken from the subclaims.
The basis for the invention is a telescoping pull-out device for household appliances and furniture, especially a pull-out system for an oven, with at least one telescoping rail supported to allow it to move between a retracted and an extended position.
It is proposed that the telescoping pull-out device includes at least one catch element for latching the first telescoping rail in the retracted position. This enables the undesirable situation to be avoided in which the first telescoping rail moves out of its retracted position and causes an obstruction. This makes for added convenience, especially with telescoping pull-out devices which are not installed precisely horizontally and during cleaning of the telescoping pull-out devices. Damage to the projecting first telescoping rail can also be avoided.
In a development of the invention it is proposed that the first telescoping rail be provided to allow it to be released from a household appliance. The advantages able to be obtained by avoiding unintentional automatic extension are particularly apparent in this case. A controllable behavior of the telescoping pull-out device or of the system can be achieved especially in a releasable system with a plurality of telescoping devices and in telescoping devices with a plurality of movable first telescoping rails.
An advantageous functional integration at maximum extension length is able to be achieved if the catch element is formed on a closure part of the first telescoping rail.
Savings in components can be achieved if a further catch element corresponding to the catch element is formed onto a carrier element.
If the catch element is provided to stabilize the first telescoping rail in the retracted position in a direction running perpendicular to a longitudinal direction of the first telescoping rail, rattling during transport and an unsightly tilting of the first telescoping rail in a non-loaded state can be avoided. In an especially simple construction the catch element can be embodied as a latching lug.
A stable latching with little force applied to establish the latching connection is achievable if the telescoping pull-out device comprises at least one catch element with an inclined surface. The inclined surface can be joined to both the first, movable telescoping rail and also to the second telescoping rail or can be formed onto the telescoping rail.
A homogeneous visual impression and a low susceptibility to contamination can be achieved if the catch element is covered at least in the retracted position of the first telescoping rail.
A telescoping pull-out device able to be pulled out beyond the length of the first telescoping rail can be achieved if the telescoping pull-out device features at least one second telescoping rail movable in relation to a carrier element, which is arranged between the carrier element and the first telescoping rail.
The result able to be achieved in this way is that the second telescoping rail in the retracted position is securely fixed between the first telescoping rail and the carrier element, if the catch element makes a direct latching connection between the first telescoping rail and the carrier element.
Furthermore the invention relates to a cooking appliance with at least one inventive telescoping device. Since there are often a plurality of non-loaded telescoping devices with pull-out telescoping mechanisms in cooking appliances with telescoping devices, an especially marked improvement in convenience can be achieved here. Furthermore the benefits with regard to the cleaning characteristics are especially significant in cooking appliances. The term cooking appliances in this context covers ovens, grills, microwave ovens, steamers and cooking appliances with combined and/or further functions.
Further advantages emerge from the description of the drawing given below. The drawing shows an exemplary embodiment of the invention. The drawing, the description and the claims contain numerous features in combination. The person skilled in the art would expediently also consider the features individually and combine them into further sensible combinations.
The figures show:
Attached to each of the carriers 28, 28′ are three parallel telescoping pull-out devices, with two forming a pair in each case on different carriers 28, 28′ and being arranged at the same height. The carriers 28, 28′ can be attached via keyhole openings in the cooking compartment of the household appliance 10 or released from this to enable the system consisting of the respective carrier 28′ and the telescoping pull-out devices connected to it (
The carrier element 20 and the first telescoping rail 12 each have an essentially U-shaped profile. The two profiles are open in relation to each other and join together to form a rectangular overall profile of the telescoping pull-out device (
Punched or formed into the front end area of the carrier element 20 is a catch element 16 embodied as a latching lug which engages with a knob-shaped catch element 14 which is formed on the closure part 18. The catch element 16 has an inclined or a sawtooth shape and features an inclined surface 30 sloping towards the end of the carrier element 20. When the first telescoping rail 12 is pushed in the catch element 14 comes into contact with the inclined surface 30 of the catch element 16 and slides over this to the end of the ramp surface 30. When it reaches the retracted position the catch element 14 latches over an end edge 32 of the inclined surface 30 of the catch element 16, so that the first telescoping rail 12 is latched via the catch elements 14, 16 in the retracted position. The catch elements 14, 16 establish a direct latching connection between the first telescoping rail 12 and the carrier element 20 (
The surface of the telescoping pull-out device is formed in the retracted position completely by the outer sides of the telescoping rail 12, of the carrier element 20 and of the closure part 18, so that the catch elements 14, 16 are covered in the retracted configuration by the first telescoping rail 12 and are protected from contamination.
Formed on an upper surface of the closure part 18 is a projection 34 protruding against the longitudinal direction 22 transverse onto a cooking area of the household appliance. In the area of a rear end of the telescoping rail 12 this features a pin 36. A cooking item carrier can be inserted between the projection 34 and the pin 36 which is connected by the pin 36 and the projection 34 in the longitudinal direction 22 with the first telescoping rail 12, so that the first telescoping rail 12 moves when the cooking item carrier is pulled out and/or pushed in together with the first telescoping rail 12.
