Description

Dish drying rack assembly structure of the dish drying rack}

The present invention relates to a hanger-type dish drying rack installed at the bottom of the sink closet to store and dry various dishes such as washed dishes, cups, and plates. More specifically, the dish drying rack and the front and rear frames of the dish drying rack. Quick connection with the left and right side plates assembled on both sides, firm connection between the front and rear frames and the horizontal and vertical bars of the dish drying rack, and quick assembly between the left and right side plates and the left and right hanger members. This relates to the assembly structure of the side plate and dish drying rack of a dish drying rack that maximizes productivity by ensuring workability, and the dish drying rack of a dish drying rack that improves the assembly of the side plate and hanger member.

Dish drying racks, commonly known as kitchen appliances, are installed on the sink and are used to wash and store dishes such as plates and rice bowls while letting the water wet in the dishes fall freely and dry naturally.

It is well known that such a dish drying rack is formed of a rod made of metal (stainless steel) and is used by placing it on the top of a sink near the faucet and sink bowl.

However, these dish drying racks occupy a lot of space due to the use of the sink, causing great inconvenience in securing work space for washing. Accordingly, when the dish drying rack is not in use, it is placed aside and used and returned to the sink when needed again. It was inconvenient to use it by placing it on the ball.

Therefore, in recent years, dish drying racks have been manufactured by welding a number of stainless steel rods in various shapes so that plates, bowls, bowls, etc. can be supported or placed on them, and a dish drying rack that is connected to the four sides of the rack to maintain the shape of the frame. A hanger-type dish drying rack, which consists of a rear frame and left and right side plates that secure the front and rear frames, and is installed at the bottom of the sink closet to improve space utilization, has been disclosed in a number of technologies.

As an example, Patent Document 1 and Patent Document 2 can be cited as examples of the applicant's first-source technology.

In Patent Document 1, a pair of grooves for frame fixing are formed on the inside of the front and rear ends, a groove for a hanger fixture and a steel rod groove are formed on the inside, and the left and right fixing plates are arranged oppositely on the left and right sides, and are molded to fit the frame fixing grooves. A dish drying rack consisting of front and rear frames assembled at both ends, four hanger fixtures each assembled in grooves for hanger fixtures, and a dish drying rack disposed between the left and right fixing plates and the front and rear frames. has begun.

In Patent Document 2, the hanger fixture composed of side plates on both sides arranged and assembled oppositely on the left and right sides of the dish drying rack has support plates on both sides with fixing grooves opening from the bottom to the top, spaced at a certain distance, and having support grooves. The hanger member, which is formed as a pair on the rear inner side and is bent in a "∩" shape with vertical supports bent on both sides of the horizontal support span, forms opposing axial protrusions at the ends of the vertical supports on both sides and is attached to the fixing groove of the support plate. The outer surfaces of both sides of the vertical support rod are accommodated and fitted from the bottom to the top to enable axial rotation with the outer peripheral surface accommodated in each support groove, and the hanger member is integrally molded as a fixture across the vertical supports on both sides so that it stands upright upon assembly. A structure of a dish drying rack has been disclosed that is configured to keep the fixture in close contact with the upper surface of the side plate when rotated and maintained in a locked state.

In this sailing technology, Patent Document 1 shows that four separately molded hanger fixtures are assembled to the left and right fixing plates by screw assembly so that the hanger member can rotate about its axis by screw assembly, and the dish drying rack is installed on the outside of the left and right fixing plates. By assembling both ends of the front and rear frames by tightening screws, there was a disadvantage in that productivity and cost increased due to the complexity of the assembly work by constructing the dish drying rack by using a plurality of constituent members and screw assembly between each constituent member.

In addition, Patent Document 2 also has the disadvantage of poor assembling as the front and rear frames of the dish drying rack are fastened with screws, and the material for molding between the shaft protrusions and fixings on both hanger members is provided with synthetic resin, so it is not suitable for injection molding. In addition to increased cost, the disadvantage is that it is deformed and broken due to deformation of the screw hole as it is fixed with screws at the bottom of the sink closet between horizontal supports due to long-term use, and is supported by shaft protrusions protruding from both sides of the end of the side plate fixing grooves on both sides. Lifespan was not guaranteed due to deformation or breakage.

In other words, the above-mentioned Patent Documents 1 and 2 have complex assembly structures of the hanger members disposed on both sides and the side frames (side plates) on both left and right sides that support the dish drying rack, and require a large number of constituent members, resulting in low manufacturing costs. There was a disadvantage in that it was difficult to maintain the assembled state for a long time because the assembly part with the sink and closet was easily damaged due to the factors that increased the pressure and the lack of a solid binding structure between the side plate and the hanger member.
