A leg support for furniture is disclosed. The leg support for furniture has a base body and a plurality of rods, characterized in that the base body is provided with a plate body having a top face for locking to the furniture, the bottom face of the plate body is provided with a plurality of sleeves for mounting with the rods such that the sleeves and the rods are formed into a structure having a strong resistance to torque; the top end of the rod is provided with a screw hole such that the rod can be urged to the sleeve by means of the upward pull of an urging bolt, thereby the leg support which can be easily assembled and dissembled is obtained.
Description




BACKGROUND OF THE INVENTION




(a) Technical Field of the Invention




The present invention relates to a leg support, and in particular, to leg support for furniture which can be assembled and dissembled easily.




(b) Description of the Prior Art




As shown in

FIGS. 1 and 2

, there is shown a conventional steel tubular seat comprising a leg support


10


and a seat pad


20


, and the leg support


10


is a bottom face of a securing plate


11


welded with four outwardly extended elongated rod


15


and the leg support


10


is locked from the bottom to the top by screw bolt


12


to the seat pad


20


.




The drawbacks of the conventional leg support are that:




1. The leg supports cannot be dissembled and therefore, it is not convenient in packaging and shipping.




2. Welding process and electroplating to the leg support are not convenient and the cost of the leg support is thus increased.




3. The leg support cannot be formed by DIY (do-it-yourself).




4. The leg support


10


will produce a torque force when a load is applied to the support. Therefore, the stress of the load will concentrate on the welded region, and therefore, the welded region is easily broken.




Therefore, it is an object of the present invention to provide an improved leg support for furniture which can obviate and mitigate the above-mentioned drawbacks.




SUMMARY OF THE INVENTION




Accordingly, it is an object of the present invention to provide a leg support for furniture having a base body and a plurality of rods, characterized in that the base body is provided with a plate body having a top face for locking to the furniture, the bottom face of the plate body is provided with a plurality of sleeves for mounting with the rods such that the sleeves and the rods are formed into a structure having a strong resistance to torque; the top end of the rod is provided with a screw hole such that the rod can be urged to the sleeve by means of the upward pull of an urging bolt, thereby the leg support which can be easily assembled and dissembled is obtained.




Yet a further object of the present invention to provide a leg support for furniture having a base body and a plurality of rods, wherein the plate body of the seat body is formed into a row of through holes for mounting to the furniture from bottom to the top thereof with bolts




A further object of the present invention to provide a leg support for furniture having a base body and a plurality of rods wherein the furniture is a chair seat or a table top.




The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.




Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments ray be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.




Referring to

FIG. 3

, there is shown a leg support


50


for furniture having a base body


51


and a plurality of rods


60


. The base body


51


is provided with a plate body


52


having a top face for locking to the furniture, such as a seat pad


70


. The bottom face of the plate body


52


is provided with a plurality of sleeves


55


for mounting with the rods


60


such that the sleeves


55


and the rods


60


are formed into a structure having a strong resistance to torque. The top end of the rod


60


is provided with a screw hole


62


such that the rod


60


can be urged to the sleeve


55


by means of the upward pull of an urging bolt


54


, thereby the leg support


50


which can be easily assembled and dissembled is obtained.




As shown in

FIGS. 3 and 5

, The top face of the plate body


52


corresponding to the center of the sleeve


55


is formed into a sunken hole


57


for locking of the rod


60


by means of a screw bolt


58


.




The rod


60


is provided with a tapered section


61


appropriately corresponded to the tapered hole


56


of the sleeve


55


and at the same time the center of the tapered section


61


is formed into a screw hole


62


. The screw hole


62


is corresponds to the sunken hole


57


of the plate body


52


such that the rod


60


can be pushed upward to the sleeve by the urging screw bolt


58


, as shown in FIG.


5


. The middle section of the rod


60


is positioned across with a limiting ring


65


and the limiting ring


65


is secured to the middle section of the rod


60


by means of screw rod


66


. This can prevent rod


60


from extended outward or displacement Thus, this structure can be assembled and disassembled easily. As shown in

FIG. 4

, there is shown a perspective view of the structure of the present invention.





FIG. 6

shows the application of the present invention on a table top. A table top


80


is directly locked to the leg support


50


and the individual rods


60


of the leg support


50


are locked by means of a linking rod


67


.




In accordance with the present invention, the advantages of the leg support are as follows:




(1) The volume of the leg support is reduced. As the rod


60


is located within the sleeves, and an urging screw bolt


58


is used for locking the rod


60


. Therefore, the structure can be dissembled in the course of shipping.




(2) Fabrication process is simple. As the parts constituted the structure can be dissembled, the individual parts can be fabricated or undergone treatment such as electroplating, without using a large electroplating tank




(3) The leg support allows variation to furniture. The rod


60


can be unloaded from the entire structure, and therefore, the rod


60


can be applied to furniture so as to provide an aesthetic appearance to fulfill an individual need.




(4) The longevity of the leg support is increased. As the joining of rod


60


to the sleeve of the seat body


51


is by means of tapered hole


56


and a tapered section


61


, the torque of the joint will be distributed to entire contact face. The longevity of the leg support is improved.




It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.




While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications and substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
