Description

Door Handle Assembly

The present invention relates to a door handle assembly, and more particularly to a door handle assembly configured to be coupled to the outer surface of the door simply and quickly to reduce the number of parts.

In general, a large-sized refrigerator for homes is made of a side-by-side type in which a refrigerating compartment and a freezing compartment are arranged in a left and right direction of a cabinet by arranging a middle partition in a longitudinal direction inside a cabinet forming an exterior. Therefore, the refrigerating compartment door and the freezing compartment door that open and close the refrigerating compartment and the freezing compartment, respectively, are arranged side by side in the left and right directions in front of the refrigerating compartment and the freezing compartment, respectively, and rotate about both ends of the cabinet.

The refrigerating compartment door and the freezing compartment door installed in such a large refrigerator are large in size, so that they are heavy. Therefore, in order to open the refrigerating compartment door and the freezing compartment door smoothly, the outer surfaces of the free end sides of the refrigerating compartment door and the freezing compartment door are respectively long in the longitudinal direction. The door handle assembly to be disposed is firmly coupled. Accordingly, when the door handle assemblies are pulled out, the refrigerating compartment door and the freezing compartment door are rotated around the hinge end to open the refrigerating compartment and the freezing compartment.

Conventional door handle assembly includes a door handle member disposed in the middle portion of the door, an upper support member disposed to extend from the top of the door handle member to the top of the door, and extend from the bottom of the door handle member to the bottom of the door. It has a lower support member disposed.

On the other hand, the door handle assembly should be made of a solid structure to smoothly rotate the heavy refrigerating compartment door and the freezer compartment door, but the door handle member and the upper and lower support members according to the prior art are made by a general injection molding method, and the structural strength thereof is increased. It becomes vulnerable, and even a slight force causes distortion.

Accordingly, the conventional door handle assembly has a structure in which a separate reinforcement member for reinforcing their strength is coupled to the front surface of the door handle member and the upper and lower support members so that the strength is reinforced. As the number of assembly parts increases, there is a disadvantage in that production cost and assembly cost increase.

In addition, the conventional door handle assembly has both ends of the door handle member and the lower end of the upper support member, and the upper end of the lower support member, respectively, to couple both ends of the door handle member with the lower end of the upper support member and the upper end of the lower support member. Couplings are provided, which are thinner when they are made in a general injection molding method, so that these couplings have separate jaws to prevent lateral flow from occurring. It is provided to have a structure to be firmly fixed to each other.

Therefore, the conventional door handle assembly is inevitably coupled to the door handle member and the upper and lower support members are made of a complex structure, it takes a lot of assembly time, there is a disadvantage that the assembly cost is further increased.

The present invention is to solve the above-mentioned problems of the prior art, an object of the present invention is to provide a door handle assembly that can be easily and quickly coupled to the door made of a simple structure.
