Definitions

• the present invention relates to a cooling device comprising a shelf the height of which can be adjusted.
• channels or rails that extend parallel to each other are disposed on the two opposite side walls of the body so that the height of the shelf can be changed.
• the user changes the height of the shelf by taking it out from the channels at one level and placing at another pair of channels at the desired level.
• the user has to first pull the shelf towards the outside of the body and push back towards the body rear wall after placing it in the channel pair at the desired height level. In order to perform this operation safely, at least some of the objects on the shelf have to be taken out and placed on the shelf again after the operation is completed.
• shelf mechanisms are used in cooling devices that allow the height of the shelf to be changed without entirely taking the shelf out of the body by means of different channel structures on the side wall. Making operations on the side wall of the cooling device is difficult and costly.

Although the horizontal position of the pin (8) changes during its movement along the guiding member (12), the shelf (5) does not move in the horizontal direction by means of the rotational movement of the connection member (7) whereto the pin (8) is connected, and moves only in the vertical direction. When aligned with the upper housing (111), the pin (8) is freed from the guiding member (12) and is seated into the upper housing (111) with the shelf (5) being pushed lightly by the user. Thus, the shelf (5) is brought to the high position (P2) and fixed in this position.
• the shelf (5) When the shelf (5) is desired to be changed from the high position (P2) to the low position (P1), the user moves the shelf (5) in the upward direction.
