The refrigerator (1) comprises a cabinet (2) wherein the foodstuffs to be cooled are placed, a door (5) that provides access into the cabinet (2), having an inner wall (3) and an outer wall (4) between which heat insulating material is injected and at least one handle (6) that provides the door (5) to be opened/closed.
The refrigerator (1) of the present invention comprises two cut-outs (7) situated on the outer wall (4) such that a distance remains therebetween.
The refrigerator (1) of the present invention furthermore comprises a fixing element (15) having

a body (8) disposed between the handle (6) and the outer wall (4),
two locking elements (11), each having a leg (9) disposed in the body (8), connected to the body (8) so as to rotate around the point to which it is connected and a foot (10) disposed at the end of the leg (9) and which extends towards between the outer wall (4) and the inner wall (3) by passing through the cut-out (7),
a channel (12) disposed on at least one leg (9) and which extends in the same direction with the legs (9),
a locking housing (13) disposed on at least one leg (9), connected to the channel (12) and which extends almost vertically to the channel (12) and
a latch (14) situated on the body (8) so as to remain between the legs (9) and rotate around its own axis, having a free position wherein it is seated into the channel (12) and which allows the two opposite edges of the legs (9) to overlap and a locking position wherein it is seated into the locking housing (13) by being rotated and which provides the legs (9) to be opened by rotating around the point they are connected and each foot (10) to bear against the edge of the cut-out (7) through which it passes.

By means of the fixing element (15), the handle (6) is fastened on the outer wall (4). During the assembly of the handle (6) on the outer wall (4), the fixing element (15) is first fastened on the handle (6) and then the fixing element (15) is fixed on the outer wall (4).
When the latch (14) is in the free position, the feet (10) are passed through the cut-outs (7). The width of the cut-outs (7) is greater than the width of the feet (10). When the latch (14) is in the free position, the edges of the legs (9), which oppositely face each other, contact each other. The latch (14) is almost rectangular shaped and when in the free position, the long edge of the latch (14) extends parallel to the channel (12). The latch (14) is brought from the free position to the locking position by being rotated clockwise or counterclockwise around its own axis almost 90 degrees. The latch (14), which is seated into the channel (12) in the free position, is seated into the locking housing (13) when brought to the locking position. While the latch (14) is brought from the free position to the locking position, the walls of the latch (14) that contact the legs (9) push the legs (9). Since the legs (9) are situated so as to rotate around the point they are connected on the body (8), the legs (9) also move with the movement of the latch (14). With the rotation movement of the latch (14), the legs (9) move away from each other and the feet (10) bear against the edge of the cut-outs (7) by moving inside the cut-outs (7). When the latch (14) changes to the locking position, the short edge of the latch (14) bears against the legs (9).
Since the latch (14) is situated between the legs (9), the legs (9) move in the opposite directions to each other with the movement of the latch (14). Thus the feet (10) move away from each other and the distance therebetween is widened. The movement of the feet (10) ends by the feet (10) bearing against the edge of the cut-outs (7). When changed to the locking position, the latch (14) is compressed by being seated into the locking housing (13). The feet (10) also bear against the edge of the cut-outs (7) and remain motionless between the outer wall (4) and the inner wall (3). Thus, the handle (6) is provided to be fastened on the door (5) by means of the fixing element (15). Thus, since the assembly of the handle (6) on the door (5) is realized without requiring any additional tool such as screw etc., labor is facilitated and cost advantage is provided.
In an embodiment of the present invention, the fixing elements (11) are situated on the body (8) such that the feet (10) face opposite directions to each other. When the latch (14) is brought from the free position to the locking position, the feet (10) move in the opposite directions to each other.
In another embodiment of the present invention, the cut-outs (7) are situated on the outer wall (4) so as to be one over the other and such that a distance remains therebetween in the vertical axis. When the latch (14) is in the free position, one of the feet (10) is passed through the cut-out (7) situated below and the other foot (10) through the cut-out (7) situated above. While the latch (14) is brought to the locking position, the foot (10) that is situated into the cut-out (7) situated below moves downwards and the foot (10) that is situated into the cut-out (7) situated above moves upwards.
In another embodiment of the present invention, the refrigerator (1) comprises a support (16) which is fastened on the inner surface of the outer wall (4) and on which at least some portion of the feet (10) bear when the latch (14) is brought to the locking position. The support (16) is fastened to the inner surface of the outer wall (4) before heat insulating material is injected between the inner wall (3) and the outer wall (4). Thus, a suitable volume is created wherein the feet (10) can extend between the inner wall (3) and the outer wall (4) by being passed through the cut-outs (7). On the other hand, the heat insulating material is prevented from protruding from the cut-outs (7) while being injected between inner wall (3) and the outer wall (4). Moreover, by means of the support (16) produced preferably from a metal material, the surface against which the feet (10) bear in the heat insulating material is strengthened. When the latch (14) is brought to the locking position, the feet (10) bear against the support (16).
In another embodiment of the present invention, the refrigerator (1) comprises at least one hole (17) which provides the body (8) to be fastened to the handle (6). The body (8) is fixed on the handle (6) by passing a fixing means such as screw etc. through the hole (17).
In another embodiment of the present invention, the refrigerator (1) comprises a pin (18) which provides each locking element (11) to be fastened on the body (8). While the latch (14) is brought from the free position to the locking position, the legs (9) rotate around the pins (18).
By means of the present invention, the handle (6) is easily assembled on the door (5) and labor and cost advantages are provided.
It is to be understood that the present invention is not limited by the embodiments disclosed above and a person skilled in the art can easily introduce different embodiments. These should be considered within the scope of the protection postulated by the claims of the present invention.
