1. Field of the Invention
The present invention relates to a table furniture assembling structure, more particularly to a table furniture which enables significant reduction of bulk volume of table and enables simplified assembling and disassembling of the table to facilitate transportation and storage.
2. Brief Description of Prior Art
Table is the most commonly used furniture facility in daily life. In addition to indoor use, table is also an indispensable equipment for outdoor barbeque, display of goods or booth furnishing. With respect to generally rectangular or square table, a table plate is mainly provided and four table legs are respectively provided to extend downwardly from the bottom end corners of the table plate. In order that the table legs can support the table plate in stable manner, additional reinforcement rods are provided to connect between the table legs and welding method is usually adopted to fix the table plate, the table legs and the reinforcement rods together. However, the table with welding for fixing is quite troublesome in transportation, and the table often occupies a lot of space when in unused condition.
In view of the negative affection on transportation and storage from undetachable structure of the conventional table, the relevant industries have proposed many improved table with collapsible legs. This table structure frequently seen in the market has its legs designed in cross intersection type with the intersection points as the pivot centers, so that the intersected legs can be either unfolded to become use state or folded to become storage state. However, as the legs after folding are overlain onto the underside of the table plate, the bottom face of the table becomes irregular so that the tables cannot be garnered in stack manner. In addition, as the legs after folding are not fastened in place, it is easy for the legs to become loosened and unfolded during transportation. This is the disadvantage frequently seen in practical implementation.
In view of the above facts, the inventor of the present invention proposes an improved table furniture according to his abundant experience in product development and manufacturing in relevant field. The object of the invention is to provide a table furniture which enables significant reduction of bulk volume of table furniture and enables simplified assembling and disassembling of the table to facilitate transportation and storage.
In order to achieve the above object, the table furniture comprises a table plate, four leg units, two couplers in a cubic shape, and a central beam. The four leg units are respectively mounted at four end corners of a table plate, and each leg unit has a leg rod and a side bracket connected with the leg rod, an engaging portion being provided at its free end. The coupler has at least three insertion slots with shrunk openings, in which two opposing insertion slots are for engagement with the engaging portions of both adjacent leg units. The central beam has an engaging portion provided at each end for engagement with one insertion slot of the couplers adjacent to the two opposing insertion slots. In this manner, by engaging/disengaging the engaging portions of the side brackets and the central beam with/from the insertion slots having shrunk openings, the assembly/disassembly of the leg units and the table plate can be achieved. In disassembled state, the table plate, the leg units and the central beam can be separately stored so that there are no such disadvantages of irregular bottom face of the table plate as happened in conventional structure. In addition, this invention can effectively reduce overall cost of transportation and storage of the table.
Furthermore, as the central beam of the present invention has engaging portions provided at both ends thereof, not only prompt assembly/disassembly of the central beam with the couplers can be achieved but also the engagement of the engaging portions of the central beam with the insertion slots of the couplers can increase the stability of the leg units.
The objects, the technical contents and the expected effect of the present invention will become more apparent from the detailed description of the preferred embodiment in conjunction with the accompanying drawings.
Firstly referring to
a table plate (1);
four leg units (2) mounted respectively at four end corners of a table plate (1), each leg unit (2) having a leg rod (21) and a side bracket (22) connected with the leg rod (21), an engaging portion (3) being provided at its free end;
two couplers (4), each having at least three insertion slots (41) with shrunk openings (411) among which two opposing insertion slots (41) are for engagement with the engaging portions (3) of both adjacent leg units (2). In this embodiment, the coupler (4) has a cubic shape;
a central beam (5) having an engaging portion (3) provided at each end thereof for engagement with one insertion slot (41) of the couplers (4) adjacent to the two opposing insertion slots (41).
Moreover, in this embodiment, each engaging portion (3) has a tapped hole (31) provided at its bottom face and the coupler (4) has a through hole (42) provided at the place corresponding to the tapped hole (31) so that the coupler (4) can be fastened to each engaging portion (3) by a fastening member (6) screwed through the through hole (42) into the corresponding tapped hole (31). Furthermore, a support plate (7) having a plurality of bores (71) provided thereon is fixed on the top end of each leg rod (21) and each leg rod (21) can be fastened to the bottom face of the table plate (1) by fastening members (6) screwed through the bores (71).
When assembling the table furniture according to the present invention, as shown in
Similarly, when the table furniture is to be disassembled for garnering, the procedure can be conducted in a direction reverse to the assembly procedure as stated above, so that the table plate (1), the four leg units (2) and the central beam (5) can be separately garnered up, and the table plate (1) can be stacked in good order. Hence, irregularity happened on the surface of the table plate after folding of the leg units as prior art is diminished in the table furniture of this invention which enables significant reduction of bulk volume of table and enables simplified assembling and disassembling of the table to facilitate transportation and storage.
Based on foregoing, the table furniture of the present invention has the following advantages when comparing with prior art.
1. As the leg units are assembled to the table plate by means of the engagement of the engaging portions with the insertion slots of couplers, assembly/disassembly of the leg units on the table plate becomes very easy and convenient and the table plate, the leg units and the central beam can be separately stored so that there is no such disadvantages of irregular bottom face of the table as happened in conventional structure. In addition, the overall cost of transportation and storage of the table can be effectively reduced.
2. As the central beam of the present invention also has engaging portions provided at both ends thereof, not only prompt assembly/disassembly of the central beam with the couplers can be achieved but also the engagement of the engaging portions thereof with the insertion slots of the couplers can increase the stability of the leg units.
The above description and illustration is merely a preferred embodiment of the present invention, not intended to limit the scope of the present invention. Variations and modifications conducted by those who are skilled in the art without departing from the spirit and scope of the present invention are still regarded to be within the scope of the invention.
