Description

Height adjustable sink leg rest {height adjustable sink leg rest}

The present invention relates to a height-adjustable sink leg support, and more particularly, to an elevating unit in which a fixing member of a hollow pipe formed to penetrate a rotating tool inside the sink is inserted into the lower surface of the sink or the fixing member is formed to adjust the height of the sink. It relates to a height-adjustable sink leg support that can be installed in a way suitable for the installation site by the constructor who installs the sink.

If furniture such as a locker or sink is not installed horizontally, deformation due to twisting or shaking occurs, reducing durability. Even when installed horizontally, it is easy to be leveled due to external shocks such as changes in storage form or repeated opening and closing.

Typically, furniture is installed on a generally flat floor surface. Furniture made of a flexible material such as wood has a problem of being crooked or tilted during use if the height of the floor is not constant. As such, it is an unavoidable fact that the bottom surface is usually bumpy even on a generally flat floor surface, so furniture installers generally use rubber, paper, and plastic materials as a medium for smoothness to keep the height of furniture constant. will do the work.

However, the flattening work using rubber or paper as a medium causes the inconvenience of placing the rubber or paper between the lower part of the furniture and the floor with a considerable height by folding the rubber or paper several times when the floor surface has severe curvature, and the difficulty of precise height control. Difficulties follow.

Therefore, height control feet or control devices for furniture are used to level the furniture when it is installed or when furniture is distorted during use, and various height control devices have been proposed in relation to their structure, function, and ease of use.

In a conventional height adjusting device for furniture, when an adjusting ring is turned while the upper body is fixed to the furniture, the upper body moves up and down by a screw coupling structure between the upper body and the adjusting ring, so that the height and overall level of the furniture can be adjusted.

However, since it is a structure that goes up and down by turning the control ring, the inside of the furniture, that is, the control foot in contact with the wall is not exposed so that it can be turned by hand. However, there is a disadvantage in that it is impossible to adjust the height of the rear height adjusting device during use with objects stored inside.

In particular, when the furniture is installed in the corner, it is inconvenient to adjust the rear legs at the corner while turning, and when the furniture is sandwiched between the furniture, the rear legs cannot be easily turned because the furniture is placed on both sides. If it is not level, it is very inconvenient to level the furniture while repeating the work of removing the furniture, turning the rear legs, and then putting it back in, so related prior arts have been proposed.

The proposed prior art furniture height adjusting device (Korean Patent Registration No. 10-1513267) relates to a furniture height adjusting device installed under the fingerboard of the furniture, and is fixed to the lower body supported on the floor and the fingerboard. An upper body portion that is threaded with the lower body portion and raised and lowered by the rotation of the lower body portion, a rotating portion rotatably installed in the upper body portion to provide rotational force to the lower body portion, and a rotating portion installed in the lower body portion and fitted to receive the rotational force of the rotating portion Characterized in that it includes a fitting portion. Therefore, the present invention has the effect that the height of the furniture can be adjusted at any time by the rotation of the rotating part by combining the upper body with the lower body and combining the rotating part with the fitting part formed in the lower body to rotate the lower body and raise and lower the upper body. provides

In the case of the prior art, since a device applied with one method among several methods for adjusting the height is used, when installing fixed furniture such as a sink, a different method is applied in order for the constructor to change the height adjustment method in consideration of the installation site conditions. There is a problem that requires the purchase of additional products.

Triangular, hexagonal, and octagonal plate shapes are also applicable. do. And a plurality of coupling holes 133 are formed so that bolts or pieces (screws) to be coupled with the lower portion of the sink 10 pass through.

The fixing member 132 is a cylindrical hollow tube protruding a predetermined length from the support part 131 so that it can be introduced into the lower surface of the sink 10 or into the inlet groove 124, and the rotary tool ( A through hole 134 is formed so that 30) passes therethrough.

At this time, the support portion 131 includes the fixing member 132 to be coupled with the support portion 131 and the second body 123 when the fixing member 132 is inserted into the lower portion of the sink 10 ( 132) is formed on the other side where the fixing groove 134 is drawn to a predetermined depth in the direction in which the fixing member 132 is formed.

The above-described sink height adjustment method according to the present invention is described in more detail as follows.

As shown in FIG. 4, when the fixing member 132 is installed to be inserted into the inlet groove 124, the user's hand passes through the space formed between the lower part of the sink 10 and the bottom surface 20. Alternatively, when a rotational force is transmitted to the gripping part 126 using a spanner, the first body 121 connected to the gripping part 126 rotates while the supporting part 131 connected to the upper end of the first body 121 ) by raising and lowering to adjust the height of the sink (10).

And referring to Figure 3, when the fixing member 132 is installed to be retracted into the lower portion of the sink 10, the user's hand or spanner through the space formed between the lower portion of the sink 10 and the bottom surface 20 Although the first body 121 may be rotated by transmitting rotational force to the gripping part 126 by using the tool, the rotary tool 30 inside the sink 10 penetrates the through hole 135 and the tool The height of the sink 10 may be adjusted by combining with the groove 125 to transmit rotational force to the first body 121 to raise and lower the supporting portion 131 connected to the top of the first body 121. .

In one embodiment of the present invention described above, the height-adjustable sink leg support 100 is to be inserted into the lower surface of the sink 10 or the inlet groove 124 to fix the hollow tube protruding from the support portion 131 for a predetermined length Since it is provided with a member 132, it is advantageous to selectively install a height adjustment method suitable for the place where the sink is installed as one part.

On the other hand, Figure 5 shows another embodiment of the height-adjustable sink leg support 200.

Elements that perform the same functions as in the previously shown drawings are denoted by the same reference numerals.

In the height-adjustable sink leg support 200 according to the present invention, when the fixing member 132 enters the lower part of the sink 10 or the inlet groove 124, the lifting unit 120 moves the support unit 130 A bearing unit 210 formed to reduce friction when rotating with respect to is further provided.

The bearing unit 210 is formed on the second body 123 and the fixing groove 134 and the corresponding surface when the fixing member 132 is inserted into the lower portion of the sink 20 to reduce rotational frictional force. When the formed first bearing 211 and the fixing member 132 are inserted into the inlet groove 124, they are formed on the corresponding surfaces of the inlet groove 124 and the fixing member 132 to generate rotational frictional force. It has a second bearing 212 formed to reduce.
