Description

Leg of sink

The present invention relates to a new structure of a sink leg capable of easily adjusting a height and a horizontal position of a sink.

Generally, in the case of a sink used in a kitchen in the home, a plurality of legs are provided on the lower side circumference.

At this time, the legs can be adjusted in length in the vertical direction, and the height or the horizontal of the sink can be adjusted by adjusting the length of the legs.

FIG. 1 shows a general example of such a sink leg, and includes a support member 3 extending upward and downward and having an upper end fixedly coupled to a lower surface of the bottom plate 1 of the sink, And an elevating member 4 screwed to an outer lower portion of the elevating member 4

Accordingly, when the user rotates the elevating member 4 in the forward and reverse directions, the lifting member 4 is lifted and lowered by screwing, and the entire length of the leg is expanded and contracted. As a result, And the horizontal can be adjusted.

However, in order to adjust the length of the sink leg, the elevator member 4 must be rotated by inserting the hand into the lower portion of the sink so that the operation is very troublesome.

Therefore, there is a need for a new method to solve such a problem.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 to 5 show a leg for a sink according to the present invention. The legs are fixed to the bottom surface of the bottom plate 1 of the sink to support the sink.

According to the present invention, the bottom plate (1) of the sink has a through hole (2) passing through the upper and lower surfaces thereof.

The legs are formed in a cylindrical shape extending in the up and down direction and have a lower end opened and a communicating hole 11 formed at the center of the upper surface and a through hole 21 passing through the upper and lower surfaces at a central portion, A fixing bolt 20 coupled from the upper side of the bottom plate 1 to the communication hole 11 through the through hole 2 to fix the supporting member 10 to the lower side of the bottom plate 1, An elevating member 30 which is formed to extend in the vertical direction and has an upper circumferential portion screwed into the inside of the supporting member 10 so as to be raised and lowered according to the rotation and having an engaging hole 31 extending upwardly and downwardly, And a rotary shaft 40 coupled to the coupling hole 31 at the lower end.

In detail, the support member 10 extends in the vertical direction and a circular engagement portion 12 having a lower end is formed therein.

At this time, a thread 11a to which the fixing bolt 20 is coupled is formed on the inner circumferential surface of the communication hole 11. [

The fixing bolt 20 is configured to have a hexagonal bolt head 23 and a screw shaft 24 extending downward from the bolt head 23 and screwed to the communication hole 11, 21 is formed to extend from the center of the upper surface of the bolt head 23 to the lower end of the screw shaft 24. [

At this time, the screw shaft 24 is configured such that a circumferential surface thereof is screwed to the communication hole 11, and the diameter of the bolt head 23 is larger than that of the through hole 2.

4, the support member 10 is disposed below the bottom plate 1 of the sink, and as shown in Fig. 5, the support member 10 is disposed above the bottom plate 1, When the bolt head 23 is inserted into the through hole 2 and the bolt head 23 is coupled to the communication hole 11 of the support member 10 using the wrench or the wrench, Is fixed to the bottom surface of the bottom plate 1 of the sink.

The elevating member 30 is formed in a cylindrical shape extending in the vertical direction, and the upper peripheral portion thereof is screwed into the engaging portion 12 of the supporting member 10.

Therefore, when the elevating member 30 coupled to the supporting member 10 is rotated in the lateral direction, the elevating member 30 is elevated and lowered by the action of the screw between the elevating member 30 and the engaging portion 12.

The coupling hole 31 is formed in the shape of a hole having a hexagonal cross-sectional shape at the center of the upper surface of the elevating member 30. [

At this time, the diameter of the coupling hole 31 is smaller than that of the through hole 21 of the fixing bolt 20.

The rotary shaft 40 is formed in a cylindrical shape having a diameter corresponding to the through hole 21 and a head portion 41 is formed at an upper end of the rotary shaft 40 so as to be engaged with an upper end portion of the fixing bolt 20, The lower end of the rotation shaft 40 is formed with a fixing groove 41a and a lower end of the rotation shaft 40 is formed with a cross section corresponding to the coupling hole 31, A portion 42 is formed.

Therefore, when the rotary shaft 40 is inserted into the through hole 21, the inserting portion 42 is engaged with the engaging hole 31 of the elevating member 30.

The bridge for a sink constructed as described above allows the user to connect the driver to the fixing groove 41a formed on the upper surface of the rotary shaft 40 from above the sink bottom plate 1 and then rotate the rotary shaft 40 using a screwdriver When the elevation member 30 is rotated, the elevation member 30 is elevated and lowered while being rotated in the forward and reverse directions to adjust the length of the leg.

The coupling hole 31 and the insertion portion 42 of the rotation shaft 40 are configured to have a hexagonal sectional shape. However, the coupling hole 31 and the insertion portion 42 of the rotation shaft 40 ) Can be configured in various forms such as a square or a triangle.

In the embodiment, the bolt head 23 is formed in a hexagonal shape. When the supporting member 10 is fixed to the bottom surface of the bottom plate 1 of the sink using the fixing bolts 20, It is also possible to connect the adapter 22 to the bolt head 23 so as to tighten the fixing bolt 20 using a screwdriver Do.

At this time, the adapter 50 is formed with a coupling groove 51 corresponding to the shape of the bolt head 23 on the lower side and a fixing groove 52 for coupling the driver to the upper side, The fixing bolt 20 is rotated together when the adapter is coupled to the fixing groove 52 and the adapter 50 is rotated after the bolt head 23 is coupled to the upper side of the bolt head 23.

Although the fixing bolt 20 and the rotary shaft 40 are separately configured as described above, the rotary shaft 40 may be rotatably coupled to the through hole 21 of the fixing bolt 20.

A ring shaped concave groove 22 is formed on the inner circumferential surface of the through hole 21 of the fixing bolt 20 and a circumferential surface of the rotary shaft 40 and a coupling protrusion 43 fitted to the concave groove 22, And the rotating shaft 40 is rotatably coupled to the inside of the through hole 21 of the fixing bolt 20. [

When the rotary shaft 40 is rotatably coupled to the through hole 21 of the fixing bolt 20 as described above, when the fixing bolt 20 is coupled to the communication hole 11, The rotation shaft 40 does not need to be separately engaged by being automatically coupled to the coupling hole 31 of the support member 10, which is advantageous in that the operation is more convenient.
