Abstract
A refrigerator has a basic structure and a door which encloses an interior. At least one refrigerated-article support which is arranged in a displaceable manner in the intrior is assigned a drive device for driving a displacement movement.
Description
- The present invention relates to a refrigerator with extendable refrigerated article supports according to the preamble of
claim 1. Such a refrigerator is known from DE 199 07 050 A1. - In the case of the known refrigerator, the article supports are guided in a displaceable manner in rails which are formed in the side walls of the inner container of the refrigerator. In these rails, the article supports can be advanced out of a rest position, in which they are fully integrated in the basic structure of the refrigerator and the door of the refrigerator can be closed, into a position in which they partially project out of the basic structure and thus facilitate access to articles which are placed in a rear region of the article support.
- The article supports have to be manually drawn out of the basic structure and pushed into the same. There is a risk here, if an article support sticks, of a user pulling the article support with too great a force in order to move it, with the result that articles set down thereon fall over.
- The object of the present invention is to improve the ease of use and the operational reliability of such a refrigerator.
- The object is achieved by a refrigerator having the features of
claim 1. - The drive device relieves the user of at least one displacement movement of the article support. The acceleration of the article support which can be produced by the drive device is limited and can easily be coordinated by the manufacturer such that there is no risk of articles tilting over during a displacement movement driven by the drive device.
- As a result of the straightforward configuration of the invention, the drive device has a spring element as the power source.
- This spring element is preferably subjected to more pronounced stressing in a position in which the article support is retracted in the interior than in a position in which it is extended out of the interior, with the result that the spring element drives a movement of the article support into the extended position. The drive power for moving the article support back into the retracted position has to be applied by the user, the spring being subjected to stressing again at the same time.
- In order to prevent unintentional extension, a catch is expediently provided for the purpose of locking the article support in the retracted position.
- An actuating element for releasing the catch is expediently fitted in an easily accessible manner for a user on an edge of the article support which is in the vicinity of the door.
- In the case of a configuration of the invention which involves higher outlay, it is also possible to provide a motor as the drive device. This motor can drive the displacement movement of the article support in both directions.
- In order for it not to take up any space in the interior of the refrigerator, the drive device is preferably incorporated in a wall of the interior.
- Further features and advantages of the invention can be gathered from the following description of exemplary embodiments with reference to the attached figures, in which:
-
FIG. 1 shows a schematic partial section through a refrigerator according to the invention with an article support in the retracted position; -
FIG. 2 shows a partial section analogous to that ofFIG. 1 with the article support in the extended position; -
FIG. 3 shows an example of a catch mechanism for locking the article support in the retracted position; -
FIG. 4 shows a schematic illustration of a first configuration of a drive device; and -
FIG. 5 shows a schematic illustration of a second configuration of a drive device. -
FIG. 1 shows a schematic section through the top region of a refrigerator having abasic structure 1 and adoor 2 which are designed as a hollow body filled with an insulating foam material and enclose aninterior 3 which is accessible via an access opening in thebasic structure 1, it being possible for the access opening to be covered by thedoor 2. Theinterior 3 contains at least one refrigerated-article support 4, which can be displaced ongrooves 5 formed in opposite side walls of theinterior 3. Adrive device 6 assigned to thearticle support 4 is illustrated schematically in arear wall 7 of thebasic structure 1. Abutton 8 on a front edge of thearticle support 4, this edge being directed toward thedoor 2, serves for releasing a catch which retains thearticle support 4 in the position illustrated. - If the
door 2 is opened and a user pushes thebutton 8 in order to release the catch, thedrive device 6 becomes active and pushes thearticle support 4 into the extended position, which is illustrated inFIG. 2 . - An example of a design of the locking mechanism is shown in
FIG. 3 in a schematic horizontal section through the front region of thearticle support 4, this region being in the vicinity of the door. The front region of thearticle support 4 has achannel 10 which is open in the direction of theside walls 9 of thebasic structure 1 and in which twocatches 11 are guided such that they can be displaced in the longitudinal direction of the channel. In the rest state, they are forced outward by springs (not illustrated), with the result that they engage inlatching recesses 12 of theside walls 9. In this state, thearticle support 4 is arrested in its retracted position. - The
button 8 engages in thechannel 10 from the front edge of the article support 4 through an opening 13. It is guided in arail 14, illustrated by dashed lines, such that it can be displaced in the direction of the arrow P. It has two flanks which each butt againstoblique surfaces 15 of thecatches 11, with the result that, when thebutton 8 is pushed in, these catches move out of thelatching recesses 12 and free the article support 4. -
FIG. 4 shows a first configuration of adrive device 6 in a horizontal section level with thearticle support 4 driven by it. Of the article support 4, only a small lateral peripheral region with a slidingblock 16 is shown, this sliding block meshing with aworm 17 which is fitted in a rotatable manner in thegroove 5, which also supports thearticle support 4. Theworm 17 is coupled, viagearwheels helical spring 20 which is accommodated in arecess 21 in therear wall 7 of thebasic structure 1. In the retracted position of thearticle support 4, thehelical spring 20 is subjected to pronounced stressing. When thearticle support 4 is unlocked, it drives a rotation of theworm 17, by means of which thearticle support 4 is advanced slowly and uniformly into the extended position. -
FIG. 5 shows a second configuration of a drive device which likewise uses ahelical spring 20, although in this case ahousing 22, which accommodates the helical spring, is incorporated in a depression of eachside wall 9 such that it crosses over thegroove 5. Agearwheel 19 coupled to thehelical spring 20 engages in thegroove 5 from beneath, through a cut-out of thehousing 22, and meshes there with alinear toothing formation 23 which is formed on an underside of thearticle support 4. The extended position of thearticle support 4 here is secured by aprotrusion 24 at the end of thetoothing formation 23, this protrusion, when it comes into contact with thegearwheel 19, blocking any further rotation thereof.
