Description

{KICKSTAND OF SINK}

The present invention relates to a footrest for furniture, and more particularly, it can be easily and easily mounted on a sink, and a height and a height for adjusting the installation height and level of a sink are made much easier and easier, The present invention relates to a height adjustable sink base leg which can be raised.

BACKGROUND ART [0002] Generally, a base for supporting and supporting furniture in a state of being spaced apart from a floor surface for ventilation and installation convenience is attached to the bottom of various kitchen furniture such as a sink or a cupboard.

Such a support leg can be horizontally adjusted at the time of installation of the furniture by adopting a structure that easily adjusts the height by turning it to the left and right by the screw fastening method in general and the height of the installation of the furniture can be arbitrarily changed by the user. Convenience can be secured.

However, when the furniture legs are mounted on a furniture, the upper surface of the furniture is closely attached to the underside of the furniture, and the furniture is rotated in various directions. Since screws and screws are tightened one by one, the assembling and mounting operations are very troublesome and inconvenient In the course of the process, several holes formed by screws are drilled on the base of the furniture, thereby damaging the furniture.

Accordingly, various types of support legs have been proposed that can be quickly mounted on furniture without using screws or the like.

For example, a bridge for a sink is disclosed in Korean Utility Model Application 2001-0002131. 1 to 3, semicircular split pieces 3 and 4 are formed on both sides of the center tube 2 of the fastening socket 1 in which the legs 20 are coupled in a threaded manner, The lower end portion 8 of the conical wedge rod 7 is fitted into the inclined hole 5 of the center tube 2 and the upper end portion 9 of the cone wedge rod 7 is united by the stopper 11 in a projected state, When the lower end of the fastening socket 1 is struck upwardly with the core tube 2 and the wedge rod 7 inserted into the groove 10, the wedge rod 7 moves the split pieces 3 and 4 to both sides And is inserted into the recessed portion 10 while being opened.

Accordingly, since the fastening socket 1 is moved up and down according to the operation of the user to rotate the legs 20, the height and the horizontal of the furniture can be easily adjusted.

However, the bottom plate of the sink is generally made of a so-called particle board which is not densely structured and has weak strength and rigidity, and has a thickness (about 3 mm) from the upper surface thereof to the bottom of the recessed portion 10 is relatively thin, The wedge rod 7 of the leg is inserted into the recessed portion 10 and the upper surface of the socket 1 is brought into close contact with the wedge rod 7 and the lower portion of the socket 1 is strongly hit with a tool such as a hammer, ) Is pierced through the recessed groove (10).

In the state in which only the wedge rod 7 and part of the split pieces 3 and 4 are fitted in the recessed groove 10 of the bottom plate, the split pieces 3 and 4 are spread on both sides by the wedge rod 7 The split pieces 3 and 4 are forced to be inserted while damaging the circumference of the inner surface of the recessed portion 10 of the furniture base so that the split pieces 3 and 4 And the recessed groove portion 10 are loosened, and when the external force is received, the coupling state easily loosens, and there is a problem such that it is shaken or gets out of the sink.

In addition, since the upper end portion 9 of the wedge rod 7 protrudes above the split pieces 3 and 4, only a part thereof is formed integrally with the split pieces 3 and 4 by the stopper 11, In case of receiving external force due to impact due to carelessness during the storage process, there is a structural limitation that separation force is easily deteriorated due to deterioration and breakage.

In addition, since the bottom surface of the leg 20 is in contact with the bottom surface and is raised and lowered with respect to the fastening socket 1, and the height of the furniture is changed by raising the fastening socket 1 in this process, The load is concentrated in the center of the lower surface of the leg 20 in a state where the height of the furniture is adjusted.

Herein, the background art or the prior art described above is only intended to help understand the technical significance of the present invention as information acquired by the present inventor or derived from the present invention, It does not mean that it is widely known in the field.
