Definitions

• the present invention relates to a refrigeration appliance, in particular a domestic refrigeration appliance such as a refrigerator or a freezer, according to the preamble of claim 1.
• Such refrigerators have a cooling space which is bounded by side walls and a rear wall, and at least one shelf, which is mounted extendable on at least one protruding from a side wall in the refrigerator space rib or rail or bar.
• a slide cam is provided on the shelf, and on the at least one rib a stop cam is provided. The arrangement is such that when pulling out of the shelf from the refrigerator out of the slide cam comes into contact with the stop cam and thus represents a limitation of the extract or the pull-out of the shelf. To remove the shelf is raised, and the cams on the side are disengaged. The removal of the shelf can thus not be achieved in a movement sequence with the withdrawal, but there are two separate movements (pulling and lifting) necessary.
• the back of the shelf is also encapsulated, because at this back an upstanding portion is to be provided, which ensures that the refrigerated goods located on the shelf of the rear wall of the refrigerator does not come too close and could freeze to it thus already mini- at least three sides of the shelf to be provided with an encapsulation. This adds complexity to the cost of the manufacturing process of each shelf.
• the present invention has for its object to provide a refrigerator with extendable shelf, in which the aforementioned disadvantages do not exist and can be made easily and inexpensively.
• the arrangement is such that a hook is provided on the shelf, which can embrace the at least one rib in the vertical direction - at least substantially - positively and, if desired, can be disengaged from the at least one rib.
• the sliding cam and the hook are arranged in the region of the rear side of the compartment floor. That it only needs the back to be designed so that the hook and the sliding cam can be arranged on it. This is true even if the shelf is to be provided on both its left and on its right side with a hook and a sliding cams.
• the arrangement is such that the hook can be brought out of engagement with the rib by a tilting movement of the front side of the shelf - and thus counter to the effect of gravity of optionally deposited refrigerated goods.
• the shelf can not tip away unintentionally when pulling out, but must be raised by a user aware to be able to be completely removed from the refrigerator can.
• the Gleitnocken and the hook are integrated into a bar which is attached to the back of the shelf.
• the bar also comprises an upwardly projecting portion, with the help of which it can be prevented that placed on the shelf refrigerated goods come too close to the rear wall of the refrigerator, which depending on the design of the refrigerator attached by one of these adjacent Refrigeration device is particularly cold.
• stop cam is formed as a projection which projects from the top of the rib down
• slide cam is formed as a projection which projects from the bottom of the shelf down
• the hook is offset relative to the slide cam to the rear.
• the hook has moved as far as possible out of the field of view of a viewer.
• the hook has a portion which protrudes from the shelf down and thus can grip the rib well in the vertical direction.
• this section also protrudes to the rear, so that the attacking Point of force, which is optionally exerted in the vertical direction when pulling out of the shelf from the refrigerator, as far back.
• the rib in this area - ie in the region of the stop cam - has on its underside a portion which recedes upward, that is, has a smaller height. This can be realized for example in the form of a gradation or flattening.
• the rib in the region of the stop cam - ie on its underside - has a height tapering from rear to front first portion which thus forms an oblique surface on its underside, ie the rib has the smallest height at its foremost end and becomes higher and higher in the course of the inclined surface towards the rear.
• the arrangement is made such that the sliding cam of the shelf, which has come in contact with the stop cam of the rib in the course of pulling out of the shelf, lifted over the stop cam away upwards and brought over this in the vertical and horizontal direction away to the outside can, after the front end of the extracted shelf has been pivoted upwards and thus the hook is moved in this area of the inclined surface during this pivoting operation and thus enough "air” was created that the slide cam can be lifted over the stop cam.
• the shelf can be carried out by means of a flowing and only deliberately made by a user movement of the top-pivoting the front of the shelf and lifting the back of the shelf with the slide cam on the stop cam away.
• the rib - viewed from the front - does not have a rectangular or square cross-section, but seen from bottom to top protrudes further and further into the cold room.
• that on the underside of the rib is formed in its width from top to bottom tapering second portion which forms a second inclined surface on its underside.
• the underside of the kens is then accordingly designed so that it has an engagement portion there whose top is substantially parallel to the second inclined surface.
• the stability of the support of the shelf in the course of pulling out of the refrigerator can be improved if one of the first rib horizontally spaced, further located at the door of the refrigerator second rib is provided on the side wall on which the shelf rests.
• the top of the second rib must be substantially flush with the top of the first rib.
• the shelf and also the respective design or contouring of the respective side walls with respect to the slide cams, stop cams and hooks are symmetrical to a center plane of the refrigeration device parallel to the side walls. That in other words, that the respective shelf at its rear side is configured identically on both sides, whereby it is guided better and more stable and held on the respective ribs.
• a particularly simple design and handling results from the fact that the rib on each upper side has a sliding surface on which the underside of the Gleitnockens can be slidably moved.
• the hook does not completely surround the rib in the vertical direction and rests against the underside of the rib with a hook, but engages from the side - ie horizontally - into the rib.
• the rib has a horizontally extending from the front to the rear portion in which a horizontally extending from front to rear groove is provided.
• the hook is arranged and engages as in the horizontal direction of the Gleitnocken projecting projection in the horizontal direction in the groove.
• the hook and the slide cam are formed as a single piece.
• the underside of this single piece forms the sliding cam which rests on the rib and slides thereon, and at the same time this underside also forms the hook which is in the Groove of the rib engages.
• the groove is substantially closed in the vertical direction, so that the hook can not be moved upwards.
• the groove Only in the region of the stop cam, the groove has an upwardly open opening through which the hook can be moved upwards.
• This opening is designed so that the hook can be moved out of this only by means of a pivoting movement of the front side of the shelf upwards and not by, for example, a pivoting movement of the shelf down (which otherwise could occur unintentionally).
• a corresponding projection and a corresponding bevel are provided at the top of the opening, which allow only a removal of the hook from the opening by the above-described pivoting movement.
• the slide cam and the hook are made of PU (polyurethane), PE (polyethylenes), PET (polyethylene terephthalate) and / or POM (polyoxymethylene), in particular attachment by injection molding onto the shelf being preferred.
