Description

IMPROVED HANDLE ASSEMBLY FOR REFRIGERATION APPLIANCE DOOR
The present invention relates to a handle-assembly for use in a door, in particular a reversible door of a refrigeration appliance such as a domestic refrigerator in which the door can be selectively mounted by a user for left-hand swing or right-hand swing. The present invention also relates to a process of manufacturing the door by using the handle-assembly.
It is common practice to provide a refrigeration appliance such as a domestic refrigerator with a reversible hinge system and a reversible handle which together allow a customer to selectively mount the pivotable door to a main body of the appliance for either left-hand or right-hand swing. When a customer purchases a domestic refrigerator, the swing direction of the door thereof may not always conform to the customer’s kitchen layout. Nevertheless, the customer may change by virtue of the reversible hinge system and the reversible handle, the swing direction of the door prior to installing the refrigerator at its designated location in the kitchen such that the door opens and closes in conformity with the kitchen layout.
In such domestic refrigerators, elements like the hinges, the handle, the plugs, the covers, the washers, and the spacers are all rendered transferrable from one side of the main body to an opposite side of the main body when reversing the swing direction of the door. Thereby, the customer is enabled to easily reverse a swing direction of the door without the need of extra elements.
The customer generally removes any plugs which conceal the demountable elements of the hinge system in order to change the swing direction of the door. Subsequently, the customer demounts the reversible handle, the reversible hinges including any washers and spacers from their current position on the main body and re-mounts the same to an opposite position on the main body.
EP 1 153 557 A1 discloses a handle for a refrigerator appliance. This handle has a couple of through-holes for mounting it to the door of the refrigeration appliance by utilizing a couple of corresponding bolts.
A drawback of this type of a handle is that the screws increase the manufacturing costs including the costs for material and labor.
An objective of the present invention is to provide a handle-assembly and a door having the same which overcomes the aforementioned drawbacks of the prior art and which enables a quick and reliable installation of the handle. Another objective of the present invention is to provide a process for manufacturing the door by using the handle-assembly.
This objective have been achieved by the handle-assembly as defined in claim 1, the door as defined in claim 9, the refrigeration appliance as defined in claim 13, and the manufacturing process as defined in claim 14. Further achievements have been attained by the subject-matters respectively defined in the dependent claims.
In the handle-assembly of the present invention, the handle has a connector which has a snap-fit portion which protrudes through a through-hole in a cover pate of the door and snap-fittingly engages with a counterpart snap-fit portion of a counterpart connector arranged inside the door. The connector and counterpart connector are provided separately from each other. In the handle-assembly of the present invention the counterpart snap-fit portion is formed in a cavity of the counterpart connector which has an opening that is arranged to face the through-hole.
The present invention also provides a process of manufacturing the door by using the handle-assembly. In the manufacturing process of the present invention the counterpart connector is immobilized relative to the cover plate by injecting foam into inner space of the door such that in the cured state of the foam the opening of the cavity faces the through-hole.
In an embodiment, the handle-assembly has a pair of connectors and a pair of counterpart connectors. The connectors are integrally provided with the opposing arms of the handle, and the counterpart connectors are arranged on one of a lateral side of the door. In a version of the embodiment, the door is rendered reversible and has an additional pair of counterpart connectors which is arranged on the other lateral side of the door. Thus, the user can selectively mount the handle to one of the lateral sides. In another version this embodiment, the unused through-holes are closed by removable plugs.
In another embodiment, the cavity has a clearance. In this embodiment, in a state where the snap-fit portion is received by the cavity, the snap-fit portion and the counterpart snap-fit portion get engaged or disengaged by manually moving the handle downwards or upwards respectively.
By the present invention, a handle-assembly has been provided which can be easily installed by using foam material. Thereby, the use of screws has been obviated and the costs for material and labor have been reduced. Due to the simplified installation of the handle, the refrigeration appliance can transported to its designated location in a state where the handle is temporally stored in a refrigeration appliance. Thus, the handle can be taken out of the refrigeration compartment and quickly mounted by a service person to the door. Thereby, the transportation becomes easier. In addition, the handle can be easily mounted on a desired lateral side of the door so as to either enable left-hand swing or right hand swing without the burden of unscrewing/screwing bolts or the like. In the door of the present invention, the counterpart connector does not protrude out of the through-hole of the cover plate, thus, a risk of damaging the same in a state where the handle is taken off during transportation has been eliminated.
