BACKGROUND OF THE INVENTION

1. Technical Field The present invention relates to designs of cabinets, and more particularly to a steel-wood composite board and a filing cabinet made thereof.

2. Description of Related Art

Filing cabinets are extensively used in offices, archives, storage rooms, and study rooms for storing office supplies, document files, and the like.

Currently, mid-to high-end filing cabinets on the market are mainly full-wood products and full-metal products. Existing full-wood filing cabinets have some defects. First, they require high transportation costs due to bulkiness and tend to have breakage during transportation. Secondly, their assembly needs numerous screws of various specifications, and is quite challenging to consumers. Thirdly, after long use, an assembled full-wood filing cabinet can become less steady when screws loose, leading to inconvenience and even danger, as testified by user comments across leading online shopping sites. Full-metal filing cabinets also have their shortcomings. For example, the relatively complicated manufacturing process means high costs and in turn high selling prices. Besides, metal plates of such cabinets are in high risks of dents and deformation, bringing about problems in terms of assembly and use.

In view of these, the inventor has devised the present invention.

Further, the steel frame has a bottom provided with a base, and the base comprises casters or wood legs or steel legs.

The present invention has the following advantages. By using the novel steel-framed wood boards as the lateral plates of the filing cabinet instead of conventional full-wood boards or full-metal boards, the present invention not only significantly reduces costs for both material and transportation by eliminating material loss during transportation, reduces the overall weight of the resulting product, and increases the overall robustness of the resulting product as compared to conventional full-wood lateral plates of the same size, but also simplifies production, reduces manufacturing costs, and eliminates the risk of board deformation during transportation as compared to conventional full-metal lateral plates of the same size. Moreover, the wood board and the steel frame of the lateral plate are factory-assembled, and the slides of the drawers are fixed to the lining plates and the steel frame through screws or rivets. As compared to the conventional products that need users to assemble lateral plates using screws, the present invention significantly improves user experience by saving users from the troublesome assembling process.

DETAILED DESCRIPTION OF THE INVENTION

The following description, in conjunction with the accompanying drawings and preferred embodiments, is set forth as below to illustrate the present invention in detail. It is to be noted that spatial descriptions, such as “up,” “down,” “front,” “back,” “left,” “right,” “top,” “bottom,” “inside,” “outside” and so forth, are indicated with respect to the orientation shown in the figures unless otherwise specified. It should be understood that the spatial descriptions used herein are for purposes of illustration only, and that practical implementations of the structures described herein can be spatially arranged in any orientation or manner, provided that the merits of embodiments of this disclosure are not deviated by such arrangement.

The present embodiment provides a filing cabinet as shown inFIG.1. Different from the existing full-wood or dull-metal products, the disclosed filing cabinet has steel-wood composite lateral plates2, wherein the lateral plates2are steel-wood composite boards. As shown inFIG.2andFIG.3, the steel-wood composite lateral plate2comprises a rectangular steel frame201and a lining plate202. The steel frame201centrally defines an enclosure for the lining plate202inlaid therein to be positioned with respect to the steel frame201. The steel frame201further comprises two steel-made vertical reinforcing pillars203. The reinforcing pillars203closely fit and are anchored to the lining plate202by rivets. Two ends of each of the reinforcing pillars203are fixed to the steel frame201through welding. Preferably, the steel frame201is made of steel tubes each having a section sized 15 mm*15 mm, and the reinforcing pillars203are made of steel tubes each having a section sized 20*10 mm. The lining plate202is made of a wood board having a thickness of 2 mm-5 mm, preferably 3 mm. As compared to the lateral plate of the conventional full-wood cabinet that has a thickness of 12 mm or 15 mm, the steel-wood composite lateral plate2used in the present embodiment is significantly strengthened.

The steel-wood composite boards are factory-assembled. As compared to the conventional full-wood cabinets or full-metal cabinets that need users to assemble lateral plates using screws, the present invention significantly improves user experience by saving users from the troublesome assembling process. Meanwhile, by using the novel steel-framed wood boards as the lateral plates2of the filing cabinet instead of conventional full-wood boards or full-metal boards, the present invention not only significantly reduces costs for both material and transportation by eliminating material loss during transportation, reduces the overall weight of the resulting product, and increases the overall robustness of the resulting product as compared to conventional full-wood lateral plates of the same size, but also simplifies production, reduces manufacturing costs, and eliminates the risk of board deformation during transportation as compared to conventional full-metal lateral plates of the same size.

Depending on the configurations and installation requirements of the cabinet in practical applications, the reinforcing pillars203may be alternatively designed as one or more of cross bars, posts, inclined rods, and arched bars. Even the steel frame201may be shaped differently.

In addition to the lateral plates2, the filing cabinet comprises a top plate1, a back plate (not shown), bottom connecting members3, and drawers4. The top plate1, the back plate, and the bottom connecting members3are all made of wood. Each of the drawers4is made of wood boards and has linear slides fixed to two sides thereof. As shown inFIG.4throughFIG.6, the rectangular steel frame201has two fastening tongues204welded thereon at sites where the top plate1to be attached to. Each of the fastening tongues204is provided with a threaded hole. Two sides of the top plate1are connected to the fastening tongues204through screws205, so that the top plate1is fixed to the two lateral plates2. In the steel frame201, the cross bars, the posts, and the reinforcing pillars203are all provided with threaded holes. Two sides of the back plate and two sides of the bottom connecting members3are all fixed to the steel frames201through screws, thereby completing installation of the back plate and the bottom connecting member. Alternatively, steel rods (not shown) are used, and both the steel rods and the steel frames201are provided with threaded holes, so that the steel rods connect the two steel frames201using screws. Then the top plate1and/or the back plate and/or the bottom connecting members3can all be fixed to the steel rods through screws. At last, the slides (not shown) of the drawers4are fixed to the vertical reinforcing pillars203through screws, thereby completing installation of the drawers4. For a drawer4equipped with a lock cylinder, a beam (not shown) may be added between the steel frames201of the two lateral plates2, so that a lock baffle can be installed on the beam to work with the lock cylinder.

Preferably, the steel frame201of the disclosed filing cabinet further has its bottom provided with casters5. Of course, these casters5may be replaced by an immovable base composed of wood legs or steel legs according to practical needs.
