Description
- This application claims priority to Brazilian Application No. PI0803841-4, filed Jul. 7, 2008, the entire disclosure of which is incorporated herein by reference.
- The present invention relates to a system for moving a set of shelves of refrigeration appliance. More particularly, the present invention relates to a system able to provide a displacement over three stable stages of a set of shelves of a refrigeration appliance so as to allow better usage of the internal space of its cabinet in accordance to the user's needs.
- The present invention also relates to a refrigeration appliance able to provide better usage of the internal space of its cabinet in accordance to the user's needs, by a system that allows the moving of a set of shelves within the said cabinet over three stages.
- Usually, the arrangement of the shelves of a refrigeration appliance is predefined at the factory, that is, the usability of the refrigerator is limited by a previously established configuration by the manufacturer. In many domestic refrigerators and/or freezers, the removal of shelves is permitted in order to allow the placement of foods or items of larger dimensions.
- The said limitation prevents the optimization of the internal space of the said cabinet, in such a manner that the user is prevented from placing a desired quantity of items inside the refrigerator or he/she is forced to put them in a disorganized manner, often stacking them randomly.
- Keeping in view the abovementioned problems, various devices have been developed so as to allow the moving/placing of shelves inside the refrigerator's cabinet in such a manner as to provide greater flexibility and usability.
- For example, the Korean document KR 100756887 relates to a set of two shelves, being that one of them is the main shelf (back) and the other one is an assistant shelf (front) which are associated to a “U” shaped frame. This frame is set up horizontally inside the refrigeration cabinet, and it comprises a flange that is able to hold (accommodate) the main shelf, which comprises an internal guide that, in association with a frame rail that is specially designed for this purpose, allows the sliding of the assistant shelf In its first stage, the main shelf and the assistant shelf remain exposed to the user, allowing the placement of foods and other items. At a second stage, the assistant shelf remains positioned internally on the main shelf, being that the last mentioned one remains exposed to the user. At a third stage, the unit made up of the main shelf and the assistant shelf is positioned orthogonally in relation to the horizontal position, by the angular rotational movement of this unit, starting from an initial horizontal position to the final vertical position.
- The Japanese document JP 8035765A discloses a set of two shelves (back and front) in refrigerators that may also be configured in three stages (stable positions). In its first stage, both shelves are accessible to accommodate foods and items to be refrigerated placed on them. In the second stage, only the back shelf is accessible for accommodating items to be placed on it (the front shelf is slid into the back shelf by means of a specially designed and constructed side rail for this purpose). In the third stage, the unit with both shelves is stabilized in a vertical position by being rotated from its horizontal position (second stage).
- In the abovementioned documents when both shelves are configured to simultaneously hold foods and items for refrigeration, they become out of alignment as the sliding mechanism is configured in such a manner so that the front shelf slides into the back shelf. This disarray may cause the foods and items for refrigeration that are on these shelves to become unbalanced, thus limiting the usage of the refrigerator as the user is prevented from placing items of larger dimensions on the shelves, due to the risk of falls or undesirable falling over.
- Beside this, the solutions presented in these documents require specially designed side rails in order to allow the movement of the set of shelves between the three stable stages, thus, the said solutions do not present a modular capacity, that is, the side rails can only be used in this specific application.
- Additionally, the need for the design and manufacturing of a specific rail for this application adds difficulty for it to be manufactured and implemented and consequently involves a higher final cost.
- Therefore, there is no known satisfactory and efficient solution which allows the optimization of the interior space of a refrigeration appliance's cabinet by a moving/dislocating system of a set of shelves between three stable stages, which will combine low cost, usability and flexibility.
- The first objective of the present invention consists of providing a low cost system that is able to allow movement/displacement of a set of shelves inside a refrigeration appliance's cabinet between three stable stages, by a solution that will allow the secure placement of foods and items of various dimensions, and which will still present usability and modularity.
- The second objective of the present invention consists of providing a refrigeration appliance that is able to allow the better usage of the internal space of its cabinet according to the user's needs, by a system that provides movement/displacement of a set of shelves between three stable stages.
- The first objective of the present invention is achieved by providing a system to move a set of shelves in a refrigeration appliance. The said refrigeration appliance comprises at least one refrigeration cabinet. The said set of shelves has at least one front shelf and one back shelf associated to each other. The said set of shelves are associable to the refrigeration cabinet by means of at least one side bar provided with at least one first accommodating portion and one second accommodating portion that are substantially flat. The mentioned front shelf is supportable on the first accommodating portion and the rear shelf is supportable by the second accommodating portion. The said first accommodating portion has a height difference in relation to the height of the second accommodating portion so as to allow a horizontal juxtaposition aligned between the front shelf and the back shelf. The mentioned front shelf is dissociable from the first accommodating portion and is able to superimpose (overlap) in relation to the rear shelf that is supportable by the second accommodating portion. The mentioned rear shelf has a end provided with a pivoting element associated in an articulated manner to the second accommodating portion of the side bar. The said pivoting element is able to allow the angular movement of the superimposed (overlapped) set of shelves from an initial horizontal position to a final substantially vertical position.
- The second objective of the present invention is achieved by providing a refrigeration appliance that comprises at least one refrigeratable cabinet that provided with at least one set of shelves. The said set of shelves comprises at least one front shelf and one rear shelf associable to each other. The said set of shelves is associable to the refrigeratable cabinet by means of a side bar provided with a first accommodating portion as well as a second accommodating portion that are substantially flat. The said front shelf is supportable by the first accommodating portion and the rear shelf is supportable by the second accommodating portion. The first accommodating portion has a height difference in relation to the second accommodating portion as to allow a horizontally aligned juxtaposition between the front and rear shelf. The mentioned front shelf is dissociable from the first accommodating portion and is able to be superimposed (overlapped) in relation to the rear shelf supportable by the second accommodating portion. The mentioned rear shelf has a first end provided with a pivoting element associated articulately to the second accommodating portion of the side bar. The said pivoting element is able to allow the angular movement of the set of the superimposed (overlapped) shelves from an initial horizontal position to a final substantially vertical position.

FIG. 16 shows a view of a detail ofFIG. 4 . -
FIGS. 5 to 10 show the side views in perspective of a shelf movement system of arefrigeration appliance 1, according to a preferred embodiment of the present invention. The saidrefrigeration appliance 1, as shown inFIG. 11 , preferably but not obligatorily, consists of a domestic/commercial refrigerator or freezer that comprises at least onerefrigeratable cabinet 2, provided with at least twoside walls 14 substantially parallel to each other and associated substantially perpendicularly to abase 15. - As shown by
FIGS. 1 to 4 , the set of shelves comprises at least onefront shelf 3 and onerear shelf 4 associable to each other. Optionally, a larger number of shelves may be used, according to the desired application. - The set of shelves that is associated to the
refrigeratable cabinet 2 by means of at least oneside bar 5 preferably being oblong and substantially parallel to thebase 15. Still in a preferential, but not mandatory manner, theside bar 5 is made from polystyrene plastic and is thermoformed, which affords lower costs in relation to injected parts. - The
side bar 5 is provided with a firstaccommodating portion 6 that is substantially flat and is able to accommodate thefront shelf 3. Theside bar 5 is also provided with a secondaccommodating portion 7 that is substantially flat and is able to accommodate therear shelf 4. In other words, thefront shelf 3 is supportable by the firstaccommodating portion 6 and therear shelf 4 is supportable by the secondaccommodating portion 7. - In the present invention, the first
accommodating portion 6 has a height difference in relation to the height of the secondaccommodating portion 7 so as to allow the horizontal juxtaposition between thefront shelf 3 and therear shelf 4. Particularly, the firstaccommodating portion 6 has a greater height in relation to the secondaccommodating portion 7, which allows the top surfaces of thefront shelves 3 and therear shelves 4 to be on the same horizontal plane, substantially parallel to thebase 15. This configuration defines the stable first stage of the set of shelves, as shown inFIGS. 2 , 5, 8 and 13. - Thus, contrary to the documents of the state of the technique, the Korean KR 100756887 and the Japanese JP 8035765A, foods and items to be refrigerated with larger dimensions may be placed on the
front 3 and rear 4 shelves simultaneously in a safe manner as they do not become misaligned. In this manner, the surface of the set of shelves is substantially continuous, without the presence of a step, providing better usability as to the first stage. - The
front shelf 3 is dissociable from the firstaccommodating portion 6 to be superimposed in relation to therear shelf 4.
