Abstract

The present invention relates to a cooling device ( 1 ) comprising a body ( 2 ) wherein the objects to be cooled are placed, at least one door ( 3 ) providing access into the body ( 2 ) and a door opening mechanism ( 4 ) situated on each door ( 3 ), having a handle ( 5 ) that rotates around the axis parallel to the short side of the door ( 3 ) and that the user moves to open the door ( 3 ), an extension ( 8 ) with at least some portion in geared form, extending from the handle ( 5 ) towards the body ( 2 ) parallel to the side wall of the door ( 3 ) and moving together with the handle ( 5 ), a latch ( 6 ) actuated by the movement of the handle ( 5 ) having a pusher ( 7 ) disposed at the end portion, providing the door ( 3 ) to separate from the body ( 2 ) and a transmission member ( 9 ) that transmits the movement of the extension ( 8 ) to the latch ( 6 ), and wherein the door ( 3 ) thereof can be easily opened and closed.

First claim

The invention claimed is:

1. A cooling device ( 1 ) comprising a body ( 2 ), at least one door ( 3 ) providing access into the body ( 2 ) and a door opening mechanism ( 4 ) disposed on the door ( 3 ), having
a handle ( 5 ) that rotates around an axis parallel to a short side of the door ( 3 ) and that a user moves to open the door ( 3 ),
an extension ( 8 ) with at least some portion defining a geared part, extending from the handle ( 5 ) towards the body ( 2 ) parallel to a side wall of the door ( 3 ) and moving together with the handle ( 5 ) and
a latch ( 6 ) actuated by the movement of the handle ( 5 ), having a pusher ( 7 ) disposed at an end portion, providing the door ( 3 ) to separate from the body ( 2 ), and a transmission member ( 9 ) disposed rotatably between the extension ( 8 ) and the latch ( 6 ), transmitting the movement of the extension ( 8 ) to the latch ( 6 ), having a geared surface ( 11 ) that contacts with the geared part of the extension ( 8 ) and a cam surface ( 12 ) that rotates the latch ( 6 ) by sliding on the latch ( 6 ).

2. The cooling device ( 1 ) as in claim 1 , wherein the geared surface ( 11 ) includes a gear diameter of which is smaller than a gear diameter of the extension ( 8 ).

3. The cooling device ( 1 ) as in claim 2 , wherein the transmission member ( 9 ) comprises a R1 distance between a rotation point thereof and an endpoint of the geared surface ( 11 ) that is smaller than a R2 distance between a rotation point and an endpoint of the cam surface ( 12 ).

4. The cooling device ( 1 ) as in claim 3 , wherein the latch ( 6 ) includes a surface contacting the cam surface ( 12 ) which is curved so as to extend from the rotation point towards the transmission member ( 9 ).

5. The cooling device ( 1 ) as in claim 4 , wherein the transmission member ( 9 ) includes a rotation point of which is almost at a lower end level of the handle ( 5 ), the latch ( 6 ), the rotation point of which is almost at a upper end level of the handle ( 5 ) and the cam surface ( 12 ) that extends between approximately the rotation point of the transmission member ( 9 ) and the rotation point of the latch ( 6 ).

6. The cooling device ( 1 ) as in claim 5 , wherein the door opening mechanism ( 4 ) comprises a support member ( 10 ), disposed on the side wall of the door ( 3 ), and whereon the extension ( 8 ), the transmission member ( 9 ) and the latch ( 6 ) are situated.

7. The cooling device ( 1 ) as in claim 6 , wherein the at least one door is two doors ( 3 ) which remain side by side when closed and one door opening mechanism ( 4 ) being situated on each of the two doors.

8. The cooling device ( 1 ) as in claim 7 , wherein the door opening mechanisms ( 4 ) are identical and disposed reverse-symmetrically on the two doors ( 3 ).

9. The cooling device ( 1 ) as in claim 8 , wherein the support member ( 10 ), the extension ( 8 ), the transmission member ( 9 ) and the latch ( 6 ) are not seen from the outside while the door opening mechanisms ( 4 ) are not used.

10. The cooling device ( 1 ) as in claim 9 , wherein the handle is plate shaped and the door opening mechanism ( 4 ) is placed on the door ( 3 ) such that the handle ( 5 ) and the door ( 3 ) are coplanar.

11. The cooling device ( 1 ) as in claim 1 , wherein the transmission member ( 9 ) comprises a R1 distance between a rotation point thereof and an endpoint of the geared surface ( 11 ) that is smaller than a R2 distance between a rotation point and an endpoint of the cam surface ( 12 ).

12. The cooling device ( 1 ) as in claim 1 , wherein the latch ( 6 ) includes a surface contacting the cam surface ( 12 ) which is curved so as to extend from the rotation point towards the transmission member ( 9 ).

13. The cooling device ( 1 ) as in claim 1 , wherein the transmission member ( 9 ) includes a rotation point of which is almost at a lower end level of the handle ( 5 ), the latch ( 6 ), the rotation point of which is almost at a upper end level of the handle ( 5 ) and the cam surface ( 12 ) that extends between approximately the rotation point of the transmission member ( 9 ) and the rotation point of the latch ( 6 ).

14. The cooling device ( 1 ) as in claim 1 , wherein the door opening mechanism ( 4 ) comprises a support member ( 10 ), disposed on the side wall of the door ( 3 ), and whereon the extension ( 8 ), the transmission member ( 9 ) and the latch ( 6 ) are situated.

15. The cooling device ( 1 ) as in claim 1 , wherein the at least one door is two doors ( 3 ) which remain side by side when closed and one door opening mechanism ( 4 ) being situated on each of the two doors.

16. The cooling device ( 1 ) as in claim 15 , wherein the door opening mechanisms ( 4 ) are identical and disposed reverse-symmetrically on the two doors ( 3 ).

17. The cooling device ( 1 ) as in claim 1 , further comprising a support member and wherein the support member ( 10 ), the extension ( 8 ), the transmission member ( 9 ) and the latch ( 6 ) are not seen from the outside while the door opening mechanisms ( 4 ) are not used.

18. The cooling device ( 1 ) as in claim 1 , wherein the handle is plate shaped and the door opening mechanism ( 4 ) is placed on the door ( 3 ) such that the handle ( 5 ) and the door ( 3 ) are coplanar.
