Description

  • The present invention relates to a refrigerator comprising a door which can be locked.
  • Doors are used to provide or block access into the body of the refrigerator. Doors having locking mechanisms are used to prevent the door from being opened by children. In the state of the art refrigerators, the locking mechanism which locks the door disrupts the aesthetic appearance of the refrigerators from outside. Furthermore, in refrigerators which can be locked and unlocked by means of a key, the user has difficulty with opening the locked door when the key is lost.
  • In the state of the art Korean Patent Application No. KR20010048304 , a refrigerator comprising a door having a child lock is disclosed.
  • In the state of the art Korean Patent Application No. KR20070093288 , a refrigerator comprising a door having a child lock is disclosed. Other refrigerator door lock solutions are disclosed in WO2008/080936 and in KR19990074446 .
  • The aim of the present invention is the realization of a refrigerator wherein the locking of the door is facilitated.
  • The refrigerator realized in order to attain the aim of the present invention, is explicated in claim 1.
  • In a preferred version of the present invention, the movement member comprises a ramp. As the movement member is slid when the pin is on the ramp of the movement member, the pin is pushed out of the housing plane or moved so as to be inserted into the housing. Thereby, most of the locking mechanism is concealed on the door. Furthermore, the locking mechanism is positioned so as not to be easily reached by children. The user can easily lock the door or unlock a locked door.
  • In an embodiment of the present invention, the refrigerator comprises two doors placed one above the other, a cavity provided on the upper door and a tongue which is positioned on the body between the two doors. As the movement member is slid when the door is in the closed position, the pin passes through the locking mechanism on the tongue and fits into the cavity on the upper door. Thus, both of the doors are locked in the closed position by sliding a single movement member.
  • In another embodiment of the present invention, the housing is provided on the upper section of the door. Thus, the housing is enabled to be positioned so as not to be reached by small children.
  • In another embodiment of the present invention, the housing is provided on the lower section of the door. Thus, the user can slide the movement mechanism easily using his/her foot.
  • In another embodiment of the present invention, the movement member has a handle. By means of the handle, the movement member can be easily moved by the user.
  • By means of the present invention, a refrigerator is realized, wherein the locking of the door is facilitated and the locking mechanism is concealed to a great extent.
  • The refrigerator realized in order to attain the aim of the present invention is illustrated in the attached figures, where:
    • Figure 1 - is the schematic view of the refrigerator related to an embodiment of the present invention.

  • The refrigerator (1) comprises a body (2); a door (3) provided on the body (2) and having an open position wherein access into the body (2) is allowed and a closed position wherein access into the body (2) is prevented, and a locking mechanism (4) which enables the door (3) to be fixed to the body (2) and locked in the closed position.
  • The refrigerator (1) of the present invention comprises the locking mechanism (4) having a tongue (6) which is disposed on the body (2) and whereon a locking housing (5) is provided, a housing (7) disposed on the door (3), a movement member (8) provided in the housing (7) and suitable to be slidably moved by the user in the horizontal plane parallel to the door, and a pin (9) which is disposed in the housing (7) and which is suitable to be moved by means of the movement member (8) and which has a released position wherein the pin (9) is almost completely in the housing (7) and a locking position wherein the pin (9) is pushed out of the housing (7) by the movement mechanism (4) so as to fit into the locking housing (5). The housing (6) is in the form of a cavity which is formed in the door (3). The movement member (8) is slid in the housing (7) parallel to the door (3). At least a part of the movement member (8) is in the form of a ramp. The pin (9) is disposed on the movement member (8). The pin (9) moves in a vertical plane perpendicular to the door (3) when the movement member (8) is moved in the horizontal plane parallel to the door (3). The pin (9) is almost completely in the housing (7) in the released position. As the movement member (8) is slid in the released position, the pin (9) is pushed by the movement member (8) from the housing (7) towards the tongue (6). The pin (9) has a locking position wherein the pin (9) fits into the locking housing (5) by being pushed by the movement member (8) when the door (3) is in the closed position. The locking housing (5) is disposed on the tongue (6) which is fixed onto the body (2). As the pin (9) extends from the housing (7) and fits into the locking housing (5), the door (3) is enabled to be fixed and locked on the body (2) in the closed position. When the movement member (8) is slid in a direction opposite to the direction wherein the pin (9) is moved from the released position to the locking position when the pin (9) is in the locking position, the pin (9) moves out of the locking housing (5) and reaches the released position.
  • In another embodiment of the present invention, the refrigerator (1) comprises two doors (3) disposed on the body (2) one above the other, the tongue (6) provided between the two doors (3), a housing (7) which is provided on one of the doors (3), a cavity (10) which is provided on the other door (3) so as to be aligned with the housing (7), and the pin (9) which fits into the cavity (10) by passing through the locking housing (5) when in the locked position and thus, enabling both of the doors (3) to be locked in the closed position. The tongue (6) is disposed onto the body (2) so as to be positioned between two doors (3). The cavity (10) is positioned on the lower section of the upper door (3) so as to be aligned with the locking housing (5). As the movement member (8) is slid when the doors (3) are in the closed position and the movement member (8) is the released position, the pin (9) passes through the locking housing (5) and fits into the cavity (10) . Thus, the two doors (3) are enabled to be locked in the closed position.
  • In an embodiment of the present invention, the refrigerator (1) comprises the housing (7) which is provided on the upper section of the door (3). In the refrigerator (1) comprising two doors (3) which are positioned one above the other, the housing (7) is provided on the upper section of the lower door (3). The movement mechanism (8) is concealed in the housing (7). A locking mechanism (4) is provided for the user, which can easily be reached by hand when he/she wants to lock the door (3) or to unlock the door (3) which is locked.
  • In another embodiment of the present invention, the refrigerator (1) comprises the housing (7) which is provided on the lower section of the door (3). Thus, the user can slide the movement member (8) easily with his/her foot. Thus, the locking of the door (3) by the user is facilitated.
  • In another embodiment of the present invention, the refrigerator (1) comprises the movement member (8) having a handle (11). The user is enabled to easily slide the movement member (8) by hand or foot by means of the handle (11). In a preferred version of the present invention, the handle (11) is in the form of a protrusion extending outwards from the housing (7).
  • By means of the present invention, a refrigerator (1) is realized, comprising the locking mechanism (4) having the housing (7) disposed on the door (3), the movement member (8) which is disposed in the housing (7) and which is moved by being slid and a pin (9) which fits into the locking housing (5) provided on the tongue (6) by being pushed by the movement member (8) when the door (3) is in the closed position and enables the door (3) to be locked in the closed position, wherein the locking of the door (3) is facilitated and the locking mechanism (4) is significantly concealed on the door (3).
