The present invention relates to a furniture leg, and in particular, a socket part provided with a coupling piece at the bottom of a cabinet inner bottom plate such as kitchen furniture, and a cap and leg body part, a support part, etc., which are coupled thereto, are installed in sequence, thereby reducing productivity and cost. It relates to a furniture leg to improve the durability while achieving this. In the configuration of the legs that can adjust the height of the kitchen furniture, which is widely known in general, as shown in FIGS. 1 to 3, the legs 3 on the inner bottom plate 2 of the cabinet-like kitchen furniture 1 ) Is provided with a circular hole 4 for fixing the top, a male screw 5 is formed on the lower side thereof, and a cap (8) on the upper side of the socket portion 8 on the hollow 7 provided with a stepped portion 6 on the upper side thereof. 9) is inserted into the circular hole (4), as well as by the mutual screw with the cylindrical leg body portion 11 formed with a female screw 10 in the center below the socket portion (8). In the drawing, the male screw 13 is installed on the support 12 which is the lower side of the kitchen furniture, which is configured to be combined with the female screw 14 formed as the inner hole of the leg body part 11. (12) Using a tool such as a screwdriver on the upper side of the leg main body 11 and supporting It is a + -shaped groove to adjust the height of the branch 12.

In the conventional kitchen furniture legs having the above-described configuration, the cap 9 is coupled to the upper portion of the socket 8 to be inserted into the circular hole 4 formed on the bottom plate 2 of the kitchen furniture 1. In this case, the cap 9 coupled to the stepped portion 6 and the hollow 7 above the socket portion 8 is caught, and the socket portion 8 protruding to the bottom of the base plate 2. The lower male screw portion 5 is coupled to the female screw 10 formed in the center and the leg body portion 11 is fixed.

On the other hand, the leg portion (3) bottom of the kitchen furniture (1) is to be screwed with the male screw 13 on the support portion 12 by forming a female screw 14 therein to be fixed to the leg body portion (11).

At this time, the stepped portion 6 above the socket portion 8 protruding from the circular hole 4 and the upper portion of the cap 9 coupled to the upper side of the cabinet-like kitchen furniture 1 inner bottom plate 2 protrude. Due to the relationship is caught in the protrusions, such as a container to be stored in the interior of the container that is stored in multiple layers to fall or break the food or spilled to appear as a main factor that dirty the inside of the kitchen furniture (1), of course, 9) and the gap between the step (6) and the bottom plate (2) is caught in the appearance and look unpleasant, there was a disadvantage that you have to keep the bowl inside the kitchen furniture dirty.

In addition, in the case of adjusting the height of the leg portion 3 according to taste, the kitchen furniture 1 is lifted up, the socket portion 8 and the leg body portion 11 are disassembled, and then a support portion is used by using a screwdriver or the like. (12) After the + magnetic grooves 15 formed on the upper side were properly turned, there was a need to assemble the socket portion 8 and the leg main portion 11 again.

In addition, the leg portion 3 consisting of the socket portion 8, the leg body portion 11 and the support portion 12 is each kitchen furniture (1) which is in contact with water and resin due to the relationship is assembled by screws The leg part 3) is not easily rusted because the internal screw easily rusts, and each component such as the socket part 8, the leg body part 11, and the support part 12 is manufactured by injection molding. There is a lot of problems, such as a cumbersome process to be screwed after, and the screw coupled to each other in the external impact, such as easy to loosen, often occurs when the leg (3) is broken.

The present invention is to improve the disadvantages and problems of the legs of the kitchen furniture as described above, the object is the socket portion and the cap coupled to the bottom portion of the cabinet inner bottom plate such as kitchen furniture and By installing the leg body part and leg support part in order so that protrusions do not protrude from the upper side of the bottom plate at all, the entire interior space is used in a sanitary state without sanitary breakage or soiling. It is to provide furniture legs for safe storage of dishes.

Another object of the present invention, the coupling of the leg portion is formed by an injection molding, not by a screw method, and the cap is coupled to the wedge shape, and the fitting wing piece is coupled to the fitting wing piece because it is securely coupled and secure.
