BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a storage cabinet, and in particular to a cabinet assembly and assembly unit thereof.

2. Description of the Prior Arts

Cabinet assemblies are used in modern society for a wide variety of storage applications. Conventional cabinet assemblies have a set appearance, monotonous design and lack variation and taste so can not satisfy various decorative needs. On the other hand, most conventional cabinet assemblies are usually composed of multiple rectangular boards and multiple regular partitions, which are connected by fasteners, such as screws, and form multiple juxtaposing rectangular rooms. The boards and partitions of a conventional cabinet assembly need to be assembled with the fasteners one by one. Therefore, assemble of the conventional cabinet assemblies is awkward and complicated.

To overcome the shortcomings, the present invention provides a cabinet assembly and assembly unit thereof to mitigate or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

The main objective of the invention is to provide an assembly unit and cabinet assembly comprising thereof that has a design for easy manufacture and convenient assembly.

An assembly unit in accordance with the present invention comprises a tapered shell and a mounting frame.

The tapered shell is hollow and has a first end, a second end, multiple sidewalls, a polygonal collar and multiple first fastener sets. The first end has a diameter. The second end has a diameter. The diameter of the second end is smaller than the diameter of the first end. The sidewalls define a cavity. Each sidewall extend from the first end to the second end, has two borders and at least one mounting slot. The two borders are respectively connected to two adjacent sidewalls. The mounting slot is formed on the sidewall near the second end. The polygonal collar is attached to the sidewalls, extends from the first end toward the second end and has multiple outer surfaces. Each outer surface is opposite to a corresponding sidewall. Each first fastener set is formed on a corresponding outer surface of the polygonal collar.

The mounting frame is hollow, is mounted around the second end of the tapered shell and has multiple attaching surfaces, multiple exterior surfaces and multiple second fastener sets. The attaching surfaces define an opening for accommodating the second end of the tapered shell. Each attaching surface has at least one mounting projection. The mounting projection corresponds to and engages with a corresponding mounting slot to connect the mounting frame and the tapered shell. Each exterior surface aligns with a corresponding outer surface of the polygonal collar of the tapered shell in a plane. Each second fastener set is formed on a corresponding exterior surface.

A cabinet assembly in accordance with the present invention comprises at least one assembly unit as described above and multiple cover plates. The cover plates are detachably attached to the tapered shell and the mounting frame. Each cover plate has a body and multiple third fastener sets. The body has a front side, a rear side, a flat top surface and a bottom surface. The third fastener sets are respectively formed on the bottom surface at the front side and the rear side of the body. Each third fastener set at the front side of the body engages with a corresponding first fastener set of the polygonal collar; and each third fastener set at the rear side of the body engages with a corresponding second fastener set of the mounting frame.

The tapered shell is suitable for manufacture by injection molding and can be easily removed from a mold. The difference between the diameter of the first end and second end of the tapered shell is filled by the mounting frame. Therefore, each outer surface of the polygonal collar of the tapered shell aligns with a corresponding exterior surface of the mounting frame in a plane, so the assembly units can be assembled parallelly.

Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
