Definitions

• the present invention relates to a cooling device comprising a height adjustable shelf.
• a refrigerator having a stepped channel formed by inclined steps, a guide that can move in the channel and that is mounted on the shelf in an angular way, and a shelf the position of which in the body is changed by moving the guide up and down in the channel
• a refrigerator which comprises two shelf supporting members formed at both side walls of the body, at least two housings disposed curvedly to each other on the shelf supporting member, at least one inclined fixing member disposed on the shelf and provides the shelf to be mounted on the shelf supporting member by being seated in the housings.
• the position of the shelf inside the body is changed by changing the position of the fixing members.
• the aim of the present invention is the realization of a cooling device which comprises a shelf disposed on the door and the position of which can be changed by being moved in the vertical direction.
• the cooling device realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises two flanges situated at two sides of the door, extending towards inside the body, a channel disposed on the flange, at least two parallelogram shaped guides, disposed at the outer surfaces of the shelf side walls, borne inside the channel, providing the position of the shelf to be changed in the vertical plane by moving inside the channel and at least one locking element providing the shelf to be fixed at the position it is changed to in the vertical plane by locking.
• the guide remains in the channel both in the carrying position of the shelf wherein foodstuffs are loaded thereon to be carried and in the movable position wherein the shelf is moved by being slid in the vertical plane.
• the position of the shelf in the vertical plane is changed by sliding the guide upwards/downwards in the channel.
• the shelf In the movable position, the shelf is provided to move freely in the channel and to remain immovable in the carrying position as the guide gets stuck in the channel by means of the guide configuration.
• the configuration of the guide limits rotation amount of the shelf in the movable position, providing the movement of the shelf to be more controllable.
• the diamond shaped guide is preferably produced with the inner angles not being equal to each other.
• the shelf remains in the carrying position when the two diagonal sides of the guide bear against inner side walls of the channel In the movable position wherein the position of the shelf is changed in the vertical plane by being rotated, one side of the guide at the most bears against one inner wall of the channel.
• the guide which rotates together with the shelf, is provided to rotate inside the channel by rotating the shelf towards inside the door plane in the carrying position.
• the guide is provided to get stuck inside the channel and the shelf to remain immovable since the sides of the guide exert pressure on both inner walls of the channel in the carrying position.
• the length of the diagonal that connects the sides of the guide bearing against inner walls of the channel is almost equal to the width of the channel. In this position, the guide gets stuck inside the channel and prevents the shelf from moving in the vertical plane.
• the shelf is changed to the movable position, at least one end of the diagonal does not contact the inner side walls of the channel and the guide can move inside the channel since the guide shifts to the inclined position.
• the shelf While the shelf is changed from the carrying position to the horizontal position, the shelf rotates in the vertical axis as much as the inner acute angle of the guide at the most.
• the acute inner angle of the guide is determined as the smallest angle possible that provides the foodstuffs in the shelf not to overturn or spill when the shelf is turned for changing position.
• the position of the shelf can be changed easily when loaded without the objects therein overturning.
• the length of the diagonal connecting sides of the guide not contacting the inner walls of the channel is determined so as to provide both sides of the shelf to move simultaneously and parallel to each other when the shelf is changed to the movable position. Consequently, the shelf is provided to be moved upwards/downwards in a balanced manner without tilting with respect to the plane of the door.
• the locking element comprises more than one housing disposed at the front of the channel so as to be parallel to the channel and arranged one on top of the other and at least two pins, disposed on opposite sides of the shelf, providing the shelf to be fixed in the vertical position that it is changed to by being seated into one of the housings.
• the pin is seated in the housing at a certain height in the carrying position of the shelf and moves freely together with the shelf by dislodging from the housing in the movable position of the shelf.
• the pin is provided to dislodge from the housing into which it is seated and provided to be seated into another housing at a different height.
• the guide is prevented from sliding in the channel due to the effect of the weight of the foodstuffs placed into the shelf in the carrying position of the shelf and the foodstuffs in the shelf are carried safely.
• the horizontal distance between the guide and the pin is determined to ensure that the pin is dislodged from the housing when the shelf changes from the carrying position to the movable position. Meanwhile, since the guide changes to the inclined position by rotating in the channel, the pin also is dislodged from the housing and becomes free to move outside the housing. Thus, the pin moves outside the housing, not preventing movement of the shelf while the shelf is in the movable position.
• springs are disposed between the housing and the flange.
• the springs prevent the shelf from moving in the horizontal plane by stretching during movements of the pin inside the housing.
• the cooling device comprises more than one sliding surface, disposed between each two consecutive housings, whereon the pin moves by sliding when the shelf is in the movable position.
• the sliding surfaces are configured to be angled. The pin slides by brushing the sliding surface while the shelf moves.
