BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a footrest for furniture such as a sink, and more particularly, to a sink leg which can be easily and easily mounted on furniture such as a sink, and can prevent a sink from being damaged in a mounting process.

BACKGROUND ART [0002] Generally, a base for supporting various kitchen appliances such as a sink or a cupboard is mounted on a bottom surface of a floor of the installation site for ventilation and installation convenience.

Such a foot bridge can easily adjust the horizontal level during the installation of the furniture by adopting a structure that freely adjusts the height of the support leg, and the height of the installation of the furniture can be arbitrarily changed according to the needs and height of the user. can do.

However, since the upper surface of a conventional furniture support leg is attached to the bottom of the furniture when it is mounted on the furniture, it is rotated in various directions while tightening the screws one by one so that the assembling and mounting work is very troublesome and inconvenient. There is a problem that furniture is damaged because a plurality of holes formed by screws are perforated on the base plate of furniture.

Accordingly, in recent years, various types of support legs have been proposed which 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. As shown in Figs. 1 and 2, semicircular split pieces 3 and 4 are formed on both sides of a center tube 2 of a fastening socket 1 to which legs 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 furniture base 2 and the upper end portion 9 of the cone wedge rod 7 is united by the stopper 11 in a protruded state, When the lower end of the fastening socket 1 is hammered upward while the center tube 2 and the wedge rod 7 are inserted into the wedge rod 7, the wedge rod 7 spreads the split pieces 3 and 4 to both sides And is stuck to the groove portion 10.

Here, the base 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 its upper surface 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 10 are loosened, and when the external force is received, the engaged state thereof is easily released, and the legs are shaken, or they are dislodged from 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.

Hereinafter, embodiments according to the present invention will be described more specifically with reference to the accompanying drawings.

Prior to this, the following terms are defined in consideration of the functions of the present invention, and they are to be construed to mean concepts that are consistent with the technical idea of the present invention and interpretations that are commonly or commonly understood in the technical field of the present invention.

In the following description, well-known functions or constructions are not described in detail to avoid obscuring the subject matter of the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

In addition, when a part includes an element, it does not exclude other elements unless specifically stated otherwise, but may include other elements.

3 to 7, a sink leg according to an embodiment of the present invention is mounted and fixed to a sink through a mounting hole G formed in a bottom plate F of a sink, A supporting portion 200 formed at a lower surface of the support portion 100 and having a predetermined height and a predetermined length and a support portion 200 screwed to the lower portion of the support portion 200, And a height adjustment unit 300 for adjusting the height of the up / down movement of the support unit 200 with respect to the support unit 200 according to the height of the support unit 200.

In order to secure a stable contact area with the base plate F of the sink, the receiving portion 100 has a predetermined width and is formed flat on the upper surface, and a dowel hole 105 communicating with the upper and lower portions is formed on at least one side.

A hollow fitting pipe 110 is formed on the upper surface of the outer periphery of the hub hole 105 so as to be inserted into a mounting hole G formed in the bottom plate F of the sink.

The fitting pipe 110 is integrally formed on one upper surface of the receiving portion 100 so that the hollow thereof communicates with the dowel hole 105 by a body divided by a plurality of cut-out grooves 111.

In other words, the fitting pipe 110 has a hollow cylindrical shape and has a flexible and resilient deformation and expansion due to a pressing force generated when the multi-wall pin 120 is press-fitted into the hollow from below. A plurality of cutting grooves 111 are formed at regular intervals.

A plurality of latching protrusions 112 are formed around the outer surface of the fitting pipe 110 at regular intervals in the longitudinal direction or the transverse direction to increase the fixation force that firmly fits the mounting hole G of the sink.

Since the cutout groove 111 is formed to completely penetrate the upper and lower surfaces of the receiving portion 100, the wall pin 120 can be more easily inserted into the hollow of the fitting pipe 110, It can be made more effective.

In addition, the locking protrusion 112 may be formed to have a predetermined length in the longitudinal direction of the fitting pipe 110, that is, the up-and-down height direction, at a certain distance radially from the center of the fitting pipe 110.

The locking protrusions 112 may be formed with a plurality of protrusions 112 at regular intervals in the up-and-down direction. The protrusions 112 may have a pointed shape gradually toward the free ends of the protrusions 112, F formed in the mounting hole G.

In the meantime, since the circumference of the hollow inner surface of the fitting pipe 110 is tapered so as to be gradually narrowed toward the upper side, the wall pins 120 are pressed into the hollow of the fitting pipe 110 in an interference fit manner The insertion tube 110 can be more naturally and easily extended by the incision groove 111 and the state in which the fitting tube 110 is more firmly and stably fixed to the mounting hole G formed in the bottom plate F of the sink .

The fitting tube 110 is pushed upward from the lower side into the hollow of the fitting pipe 110 through the dowel hole 105 at the lower portion of the receiving portion 100 corresponding to the fitting pipe 110, A plurality of wall pins 120 are integrally formed so as to maintain a state of being embedded in the mounting hole G of the sink.

That is, the dowel pin 120 is disposed such that its central axis is located on the same line as the center axis of the fitting pipe 110.

The outer diameter of the diaphragm 120 is slightly larger than the inner diameter of the diaphragm 110. The end of the diaphragm 120 facing the diaphragm 105 is smoothly inserted into the hollow of the fitting tube 110, The outer diameter is gradually narrowed toward the hub hole 105 so as to be easily inserted into the hub hole 105. As shown in Fig.

In order to form the dowel pin 120 at a certain distance from the dowel hole 105 and to form the outer diameter of the dowel pin 120 larger than the inner diameter of the fitting tube 110, A molding space 130 for guiding the slide core of the mold to open and close is formed at a predetermined height so as to surround the dowel pins 120.

That is, since the molding space 130 is naturally formed by the space for guiding the slide cores of the mold for injection molding to freely move in three directions (both sides and the lower surface of the receiving portion 100) The outer diameter of the inner tube 120 may be larger than the inner diameter of the fitting tube 110 while being spaced apart from the hub bore 105 by a predetermined distance.

The molding space 130 surrounds the wall pin 120 so as to prevent the stopper 140 from being easily broken when the multi-wall pin 120 receives an external force due to contact with the outside or carelessness. As shown in FIG.

If the molding space 130 is not provided, the wall pins 120 are spaced apart from the dowel holes 105 by a predetermined distance, and the outer diameter of the wall pins 120 is larger than the inner diameter of the fitting tube 110, It is necessary to form the dowel pin 120 into a shape connected to the dowel hole 105 as a result of the conventional method. As a result, the dowel pin 120 is inadvertently inserted into the dowel hole 105 during handling such as transportation and storage, Can not be easily prevented from being deformed and broken (separated).

When the wall pins 120 are inserted into the hollow of the fitting pipe 110, they are broken and cause contact interference with the receiving portion 100 around the fixing holes 105. When the wall pins 120 are inserted into the mounting hole G, The stopper 140 is integrally formed so as to connect a part of both sides of the outer surface of the wall pin 120 and the inner wall of the molding space part 130 to each other.

In order to prevent the dowel pin 120 from entering the hollow of the fitting tube 110 beyond a certain range due to contact interference between the stopper 140 and the receiving portion 100, The length from the end facing the hole 105 to the stopper 140 is slightly longer or equal to the length of the fitting tube 110.

A portion of the stopper 140 connected to the inner wall of the molding space 130 is formed to have a relatively small thickness so as to be easily broken, and a portion connected to the multi-wall pin 120 is formed to have a predetermined thickness have.

That is, a part of the outer circumferential face of the dowel pin 120 and the inner wall of the molding space part 130 are connected to each other by a thin and thin notched cutout part 141, And is separated from the inner wall of the molding space part 130 while being naturally broken when impacted or hit (priced).

In other words, both sides of the wall pin 120 are integrally connected to at least one stopper 140 and a part of the inner wall of the molding space part 130 opposite to the stopper 140. When the stopper 140 receives an impact due to an external force The upper end of the wall pin 120 is press-fitted into the hollow of the fitting pipe 110 through the dowel hole 105. At the same time, the upper end of the wall pipe 120 is inserted into the fitting pipe 110, So that it is pressed firmly into the mounting hole G formed in the base plate F of the sink.

7, when the dowel pin 120 is press-fitted into the hollow of the fitting pipe 110, the portion of the stopper 140 connected to the dowel pin 120 is inserted into the hollow of the fitting pipe 110, In order to prevent direct contact with the mounting hole G formed in the mounting hole.

When the free end of the stopper 140 is cut off by cutting the cutout portion 141 of the stopper 140, the free end of the stopper 140 can be easily bent and easily deformed as it is in the vertical direction. Therefore, It is preferable that the stopper 120 and the stopper 140 are integrally formed by a reinforcing member 142 that increases strength and rigidity as shown in Fig.

At least one nail hole 150 is formed at the other side of the receiving portion 100 so that the fixing nail 160 can be stuck to the bottom plate F of the sink through the nail hole 150 .

That is, the supporting part 200 is integrally formed at the center of the lower surface of the receiving part 100, and the fitting pipe 110 and the nail hole 150 are formed with the supporting part 200 interposed therebetween.

Here, the fixing nails 160 may have a sharp end and a plurality of inverted tine-like protrusions on the outer periphery, and may adopt a length longer than the length of the nail hole 150 for stable and easy operation and operation .

The supporting part 200 is formed in a hollow cylindrical shape having a predetermined height so as to be positioned in a state where the receiving part 100 is spaced apart from the bottom surface by a predetermined height and is integrally formed on the lower surface of the receiving part 100.

That is, the support portion 200 is formed in a cylindrical shape having a width and a diameter smaller than the vertical and horizontal widths of the receiving portion 100 when viewed on a plane.

A thread 210 is formed around the lower inner surface of the support part 200 so that the height adjusting part 300 can move up and down with respect to the support part 200 and adjust the height of the support part 200 in a screw- have.

The height adjuster 300 adjusts the installation height of the sink with respect to the floor by varying the length thereof with respect to the support 200. The height adjuster 300 can elevate and lower the support 200 in accordance with the rotation operation about the support 200 To the threads 210 of the support 200 in a threaded manner.

That is, the height adjustment part 300 is formed in a hollow cylindrical shape, and the male thread 310 is formed around the outer surface of the height adjustment part 300 so as to be threadedly engaged with the female thread 210 formed around the inner surface of the support part 200 And a plurality of projections and depressions are formed radially around the outer surface of the lower portion to prevent slippage during gripping according to the height adjustment.

In the above description and accompanying drawings, male and female threads are formed around the inner surface of the support part 200 and the outer surface of the corresponding height adjustment part 300, A male screw thread may be formed around the side surface and the inner surface of the elevation adjusting portion 300 facing the side surface so that the height adjusting portion 300 may be screwed to the lower portion of the supporting portion 200 while being engaged with each other Of course it is.

The thread 210 of the support part 200 and the thread 310 of the height adjusting part 300 are easily worn out like the isosceles trapezoid or the like so that the shape of the cross section can be easily rotated while stably supporting the load of the furniture It is preferable to form it in a non-shape.

In addition, a pivot projection 320 is provided at the center of the bottom surface of the height adjuster 300 to minimize the contact with the floor surface in the state of being installed on the furniture, and to allow the turning operation for adjusting the height to be smooth and smooth desirable.

The sink leg according to the embodiment of the present invention can be formed by injecting thermoplastic plastic into a metal mold. At this time, unnecessarily thick portions are formed by weight reduction and rib shaping so as to be lightweight and to maintain a constant strength, thereby reducing costs and lightening the parts.

The sink leg according to the embodiment of the present invention having such a structure is inserted into the mounting hole G formed in the bottom plate F of the sink so that the upper surface of the receiving unit 100 is inserted into the bottom plate F of the sink, When the bottom surface of the dowel pin 120 is strongly hammered by a tool such as a hammer or the like in a state in which the dowel pin 120 is in close contact with the outer surface of the dowel pin 120 and the part of the dowel 140, The upper end of the multi-wall pin 120 is press-fitted into the hollow of the fitting pipe 110.

7, the fitting pipe 110 is extended outwardly by the contact force and the pressure input of the wall pins 120, so that the locking projections 112 are pinched around the inner surface of the mounting hole G So that it can be maintained in a state of being fixed primarily to the base plate F of the sink.
