Definitions

• the invention relates to a refrigerator, such as a refrigerator, a fridge-freezer or the like, with a heat-insulating housing, within which a cooling space with at least one drawer-like storage compartment is provided, which has a door and which on its two long sides on the basis of at least approximately rollers arranged opposite each other in pairs are movably supported, rollers arranged on the storage compartment leading in the direction of insertion of the storage compartment and stationary at least approximately in the vicinity of the access opening to the cooling space, each of which is supported in a rolling manner on a correspondingly assigned guideway.
• a refrigerator such as a refrigerator, a fridge-freezer or the like
• a heat-insulating housing within which a cooling space with at least one drawer-like storage compartment is provided, which has a door and which on its two long sides on the basis of at least approximately rollers arranged opposite each other in pairs are movably supported, rollers arranged on the storage compartment leading in the direction of insertion of the storage compartment and stationary at least approximately in the vicinity of the access opening
• the invention has for its object to avoid the disadvantages of the prior art in a refrigerator according to the preamble of claim 1 with simple design measures.
• At least one of the guideways has two adjoining inclined planes of different lengths, which form a vertex at the connection point, with respect to the of the top of the inclined plane exerts a driving force on the storage compartment to the refrigerator.
• the inventive design of at least one of the guideways divides the extension path of the storage compartment that is determined by it into two differently long path sections formed by ramp-like inclines, of which a defined automatic opening into its end position with a defined and shortened position is only overcome after the longer path section has been overcome Acceleration distance is effected. Due to the deliberately created opening of the storage compartment up to its end stop, an at least substantially predeterminable final speed occurs for the storage compartment, which, owing to the shortening of the path, is significantly lower than the final speed which occurs in drawer-like storage compartments which are made according to the prior art.
• the different length dimensions of the inclined planes mean that the storage compartment is automatically moved back into its closed position in the majority of opening cases and is therefore energy-efficient for the refrigeration appliance, the closing speed of the storage compartment being particularly simple due to the inclined position of the longer one Guideway and its length can be influenced.
• the crest-like, reversing connection of the two inclined planes means that the operator of the storage compartment is relatively clearly signaled that the vertex serving as the reversal point has been exceeded, and the operator thus receives clear information as to which opening position of the storage compartment either resets it in its Closed position or is forced into its open position.
• a refrigeration device with guideways provided on the side walls of the cooling space, which are provided with a toothed rod-like toothing are provided, in which two at least approximately rigidly coupled, at least axially opposite, with an external toothing of the same pitch circle diameter are provided, which are formed by the leading rollers, it is provided that the two inclined planes are arranged on the side of the storage compartment Guideways are provided.
• the arrangement of the guideways on the storage compartment means that they are particularly simple and targeted to match the respective storage compartment with regard to its extension path and its capacity, both in terms of the length and the inclination of the inclined planes.
• the guideways composed of different lengths of inclined planes are particularly easy to manufacture if, according to a further advantageous embodiment of the object of the invention, it is provided that the guideways with different lengths of inclined planes on the storage compartment on the longitudinal sides thereof, on the underside of spar-like supporting elements are arranged.
• the movement of the storage compartment caused by the inclined planes is particularly uniform if, according to a next preferred embodiment of the object of the invention, it is provided that the inclined planes have at least essentially the same angle of attack with respect to a horizontal.
• the shorter, oblique plane is followed by an at least approximately horizontally arranged guide section.
• the length of the inclined planes is particularly expedient if, according to a further preferred embodiment of the object of the invention, it is provided that the adjoining inclined planes and the horizontal guide section at least essentially define the extension path of the storage compartment.
• the longer inclined plane has a length in the range between 50% to 90% but preferably 80% of the extension path of the storage compartment.
• Such a division of length between the shorter inclined plane and the longer inclined plane ensures, on the one hand, in the predominant cases of operating the storage compartment according to the invention that it is automatically moved into its closed position after an opening operation.
• the unequal division of length between the shorter and longer oblique plane in favor of the latter has the advantage that an operator supports the closing movement by the longer oblique when moving the storage compartment from its open and closed positions after overcoming the shorter, shorter oblique plane Experience level when closing the storage compartment.
• the drawer-like storage compartment is held particularly securely within the horizontal guide section defining the open position of the storage compartment if, according to a last preferred embodiment of the object of the invention, it is provided that a catch is provided at the transition between the shorter inclined plane and the horizontal guide section.

If the user remains in his pull-out movement in the pull-out direction of the storage compartment 22 in front of the apex 37, the storage compartment 22 is automatically brought into its rest position in the cooling space 14 by the inclined plane 36.
