Definitions

  • the present invention relates to a cooling device comprising a movable carrier.
  • cooling devices have a freezing compartment for freezing and storing foodstuffs or beverages, and a fresh food compartment for storing foodstuffs or beverages at low temperatures.
  • the fresh food compartment and the freezing compartment may have shelves, drawers, baskets and similar carriers arranged to store foodstuffs therein.
  • Various foodstuffs to be stored by cooling or freezing are conveniently stored in a shelf, drawer, basket, etc. in the fresh food compartment and freezing compartment.
  • Drawers, shelves and baskets can be arranged in a variety of ways in the fresh food and freezing compartments so as to store foodstuffs in different sizes, requiring different storage conditions.
  • the shelves, drawers and similar carriers most used by the user are usually those located at eye level of the user. Therefore, the carriers above this level are used less frequently, which reduces the usage efficiency of the storage volume of the cooling device.
  • the cooling devices where the freezing compartment is located at the top, the user stacks the products and encounters difficulties especially in reaching the products at the rear. Since the products remaining behind are out of sight, said products may be forgotten, which leads to spoilage of foodstuffs. It is even more difficult for a short user to organize the freezing compartment and reach the products at the rear.
  • a cooling device comprising a shelf mechanism wherein in order to increase the usage efficiency, the level of the shelf located on the upper level of the storage volume is shifted to a level that the user can access more easily.
  • a cooling device comprising a shelf which can be moved to a position easily accessible by the user by changing the height thereof by means of a simple mechanism.
  • the aim of the present invention is the realization of a cooling device comprising a carrier which can be moved to a level easily accessible by the user, thus increasing the usage efficiency of the storage volume.
  • 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 a carrier which has a first part and a second part arranged one behind the other in the same horizontal plane; a rail mechanism which enables the carrier to move in the horizontal axis when the latter is pulled forwards in the horizontal axis; and a movement mechanism which, after the first part is detached from the rail mechanism, enables the first part to move to a level under the level of the second part in the vertical axis.
  • both the first and second parts which constitute the carrier are horizontally positioned at the same level in the horizontal axis in the cooling device such that the first part is in the front and the second part is at the back.
  • the first and second parts move together in the horizontal axis to a position at the front side of the cooling device. This horizontal movement continues until the first part is detached from the rail mechanism. In this case, the first part is completely detached from the rail mechanism while the second part bears against the end of the rail mechanism and is moved to a position at the front side of the cooling device.
  • the first part moves down in the vertical axis as connected to the movement mechanism to be positioned at a level below the level of the second part.
  • the rail mechanism is composed of two rails placed in parallel, in the horizontal direction, on the two side walls of the cooling device, extending from the back to the front.
  • the rail mechanism comprises a stopper at each end of both rails. While allowing the first part of the carrier to be detached, said stopper prevents the second part from being detached from the rail.
  • the carrier comprises at least two wheels on both sides of the first and second parts, which engage with the rail in the rail mechanism, preferably five wheels in the first part and four each in the second part.
  • the diameter of the wheels in the second part is larger than the diameter of the wheels in the first part.
  • the movement mechanism has two parallel guides located on the side wall of the second part, and slides fixed on the side wall of the first part, extending to the guides in the second part and entering the guides so as to move in the guides.
  • the guides are inclined from back to front, from top to bottom. By means of this inclination, the first part moves forward and downward.
  • the balancing mechanism comprises a main gear on the second slide which engages with the second guide, a pulley parallel to the second guide, that said main gear contacts, and at least two pulley gears disposed in the pulley.
  • the lowermost two pulley gears are connected to each other by means of a balancing rod.
  • the cooling device further comprises a spring mechanism with one end connected to the side wall of the first part and the other end connected to the side wall of the second part at the same level while the first and second parts are aligned.
  • the spring mechanism comprises a spring and a piston integrated with the spring.
  • the carrier is brought to a level easily accessible by the user such that the storage volume is used efficiently.
  • the problems encountered in loading and unloading products on the carriers in the freezing compartment located at the top of the cooling device are eliminated by means of the present invention. While it becomes easier for the user to load products on the carrier, it is ensured that the products at the rear section of the carrier can be easily accessed.
  • the cooling device (1) comprises at least one compartment (2) wherein products are stored; a door which provides access into the compartment (2); a carrier (4) which is disposed into the compartment (2) and which has a first part (5) and a second part (6) arranged one behind the other in the same horizontal plane; a rail mechanism (9) which is disposed on the side walls of the compartment (2) and which enables the carrier (4) to move in the horizontal axis when the latter is pulled forwards in the horizontal axis; and a movement mechanism (12) which, after the first part (5) is detached from the rail mechanism (9), enables the first part (5) to move to a level under the level of the second part (6) in the vertical axis.
  • both the first and second parts (5 and 6) which constitute the carrier (4) are horizontally positioned at the same level in the horizontal axis in the compartment (2) such that the first part (5) is in the front and the second part (6) is at the back ( Figure 1 and Figure 5 ).
  • the first and second parts (5 and 6) move together in the horizontal axis to a position at the front side of the cooling device (1).
  • This horizontal movement continues until the first part (5) is detached from the rail mechanism (9).
  • the first part (5) is completely detached from the rail mechanism (9) while the second part (6) bears against the end of the rail mechanism (9) and is moved to a position at the front side of the cooling device (1) ( Figure 2 ).
  • the first part and the second part (5 and 6) comprise two parallel side walls (7) and one rear wall (8) each which joins said two side walls (7).
  • the rail mechanism (9) comprises two rails (10) placed in parallel, in the horizontal direction, on the two opposite side walls (3) of the compartment (2), extending from the back to the front.
  • the rail mechanism (9) comprises a stopper (11) at each end of both rails (10). While allowing the first part (5) of the carrier (4) to be detached from the rail (10), said stopper (11) prevents the second part (6) from being detached from the rail (10) ( Figure 4 ).
  • the carrier (4) comprises at least two wheels on both sides of the first and second parts (5 and 6), which engage with the rail (10) in the rail mechanism (9), preferably five wheels in the first part (5) and four each in the second part (6).
  • the diameter of the wheels in the second part (6) is larger than the diameter of the wheels in the first part (5).
  • the movement mechanism (12) comprises a first guide (13) and a second guide (14) which are located parallel to each other on both side walls (7) of the second part (6); a connection member (26) which fixed to both side walls (7) of the first part (5) and which extends until the first and second guides (13 and 14) on the second part (6); and a first and second slide (15 and 16) which enter the first and second guides (13 and 14) on the connection member (26) so as to move in the first and second guides (13 and 14), with one entering the first guide (13) and the other entering the second guide (14).
  • the first and second guides (13 and 14) are inclined from back to front and from top to bottom. By means of this inclination, the first part (5) moves forward and downward.
  • the first and second guides (13 and 14) are a slit.
  • the balancing mechanism (17) comprises a main gear (18) on the second slide (16) which engages with the second guide (14), a pulley (19) parallel to the second guide (14) that said main gear (18) contacts, and at least two pulley gears (20) disposed in the pulley (19).
  • the lowermost two pulley gears (20) are connected to each other by means of a balancing rod (21).
  • the pulley (19) is a geared pulley.
  • both sides of the first part (5) move an equal distance at equal speed such that the first part (5) moves in a balanced way, eliminating the problems which may arise due to unbalanced loading.
  • the cooling device (1) further comprises a spring mechanism (22) with one end connected to the side wall (7) of the first part (5) and the other end connected to the side wall (7) of the second part (6) at the same level while the first and second parts (5 and 6) are aligned.
  • the spring mechanism (22) comprises a spring (23) and a piston (24) integrated with the spring (23).
  • the cooling device (1) comprises a handle (25) which is disposed on the front side of the first part (5) in front of the carrier (4) and which enables the user to grip and pull the carrier (4).
