Furniture frame leg structure according to an embodiment of the present invention consists of a leg frame 10, the horizontal support 20 and the coupling bracket 30.

The leg frame 10 is a metal frame formed of a square tube. Preferably, the cross section of the leg frame 10 is formed in a rectangle having a vertical width longer than a horizontal width. Referring to FIG. 3, one leg frame 10 is formed of a straight material having a length corresponding to a width between both legs and legs. In the straight leg frame 10, the V-cutting is performed at the position where the legs are bent, respectively. 3, the cutting portion 11 of the leg frame 10 is shown. Cutting portion 11 is formed in the shape of a right angle isosceles triangle with a point corresponding to the thickness length of the upper surface of the leg frame 10 from the top surface.

After cutting the leg frame 10 is bent so that the cutting surface of the cutting portion 11 abuts to form a leg '' 'shaped.

The cutting surface of the leg frame 10 is bent and abuts. At this time, welding may be made to the lower ends 11a and 11b of the cut and abutted surface. Since this part is not a part that appears in appearance in a combined state, welding may be performed and the leg frame 10 serves to support the opening.

Coupling holes 12a and 15a to which coupling brackets 30 to be described later are fastened are formed at left and right sides of the cutting part 11 of the leg frame 10.

It is to support one side of the upper plate 50 with the leg frame 10 formed as above, and to set up one leg frame 10 on each of the lower both sides of the upper plate 50.

The horizontal support 20 is a metal frame formed of a square tube. Preferably, the cross section of the horizontal support 20 is formed in a square, the length of one side is formed to be equal to the length of the short side of the rectangular side of the cross section of the leg frame (10). A plurality of fixing holes for supporting the upper plate 50 are formed in the middle portion of the horizontal support 20.

Horizontal support 20 is a support that is placed between the two leg frame (10). Commonly used as a method for connecting the horizontal support to the leg frame is a welded or screwed. However, it is not easy to align vertically when welding to join one member vertically to the side of another member. In addition, even when screwed using a separate bracket was not designed to make a smooth connection. In the example according to an embodiment of the present invention, a cross bracket is easily assembled at right angles by a coupling bracket 30 which will be described later, and a welded portion is firmly formed without being exposed, and a screw coupling is reduced.

Coupling bracket 30 is a component that is coupled to the leg frame 10 and serves to support the horizontal support 20.

Coupling bracket 30 is composed of a horizontal plane 31 and a vertical plane 32 having a predetermined width and formed in a 'b' shape. The center portion of the horizontal surface 31 is opened with the same width as the width of the horizontal support 20, and the opening portion is formed with the same width and depth as the width of the horizontal support 20 in the center portion of the vertical surface 32.

Coupling holes 31a and 32a are formed in the left and right sides of the center portion of the horizontal surface 31 and the left and right sides of the center portion of the vertical surface 32, respectively. The coupling hole 32a of the coupling bracket 30 is positioned and screwed into the coupling hole 12a of the leg frame 10. In this case, the position of the upper surface of the horizontal surface 31 is preferably such that a slight gap is formed with respect to the position of the lower surface of the upper plate 50. By doing so, when the upper plate 50 and the horizontal support 20 are fastened with screws, a minute gap can be maintained so as not to be released. Alternatively, a spacer may be inserted between the upper plate 50 and the horizontal support 20.

The horizontal support 20 is placed on and supported by the opening 33 of the coupling bracket 30. Since the cross section of the horizontal support 20 is square and the opening part 33 also forms a right angled surface, the end of the horizontal support 20 needs only to be placed on the opening part 33 of the coupling bracket 30 so that the assembly is excellent. Do. The side surface 33a of the opening part 33 is a part which abuts on the side surface of the horizontal support 20, and this part is joined by welding. Since the surface to be joined by welding is formed in three dimensions, compared to the conventional method of welding the circumference of the 'ㅁ' shape on the plane by attaching the coupling member to one side of the member to be joined, it is much better.

Preferably, referring to FIG. 5 as another embodiment of the coupling bracket 30, the wing piece 34 is bent and extended to the lower end of the coupling bracket 30 of the above-described embodiment is shown. The wing piece 34 is formed at a right angle with respect to the vertical surface 32 as a part that is coupled to the lower end of the leg frame 10, and thus is precisely fastened to the leg frame 10, so that the assembly is good and, if necessary, the wing piece A screw hole may be formed in the 34 to be fastened to the bottom surface of the leg frame 10 using a screw or the like to reinforce the supporting force.

Preferably, a support bracket for joining around the cutting portion may be additionally installed to reinforce the cutting surface of the leg frame 10, and this object may be achieved by forming the coupling bracket 30 by deformation. It may be.

An extension surface 35 may be formed on one side or both sides of the vertical surface 32 of the coupling bracket 30. The extended surface 35 is located at the corner formed by the leg frame 10 is bent and screwed (15a, 35a) to support the cutting portion 11 of the leg frame (10).
